“Depending on whom you ask, “healthy eating” may take many forms. It seems that everyone, including healthcare professionals, wellness influencers, coworkers, and family members, has an opinion on the healthiest way to eat. Plus, nutrition articles that you read online can be downright confusing with their contradictory — and often unfounded — suggestions and rules. This doesn’t make it easy if you simply want to eat in a healthy way that works for you.”

Author Jillian Kubala is a registered dietitian and holds a master’s degree in nutrition and an undergraduate degree in nutrition science. In her essay, she says that healthy eating doesn’t have to be complicated and explains how it can nourish your body while enjoying the foods you love. Check out these essays about health .

“Eating provides your body with the nourishment it needs to survive. A healthy diet supplies nutrients (such as protein, vitamins and minerals, fiber, and carbohydrates), which are important for your body’s growth, development, and maintenance. However, not all foods are equal when it comes to the nutrition they provide. Some foods, such as fruits and vegetables, are rich in vitamins and minerals; others, such as cookies and soda pop, provide few if any nutrients. Your diet can influence everything from your energy level and intellectual performance to your risk for certain diseases.”

Author Jaime Padilla talks about the importance of a healthy diet in your body’s growth, development, and maintenance. He also mentioned that having a poor diet can lead to some health problems. Check out these essays about food .

“Eating healthy is about balance and making sure that your body is getting the necessary nutrients it needs to function properly. Healthy eating habits require that people eat fruits, vegetables, whole grains, fats, proteins, and starches. Keep in mind that healthy eating requires that you’re mindful of what you eat and drink, but also how you prepare it. For best results, individuals should avoid fried or processed foods, as well as foods high in added sugars and salts.”

Author Maggie Smith believes there’s a fine line between healthy eating and dieting. In her essay, she mentioned five benefits of eating healthy foods – weight loss, heart health, strong bones and teeth, better mood and energy levels, and improved memory and brain health – and explained them in detail.

“From old generation to the new generation young people are dying out quicker than their own parents due to obesity-related diseases every day. In the mid-1970s, there were no health issues relevant to obesity-related diseases but over time it began to be a problem when fast food industries started growing at a rapid pace. Energy is naturally created in the body when the nutrients are absorbed from the food that is consumed. When living a healthy lifestyle, these horrible health problems don’t appear, and the chances of prolonging life and enjoying life increase.”

In her essay, author Audrey Rodriguez says that having self-control is very important to achieving a healthy lifestyle, especially now that we’re exposed to all these unhealthy yet tempting foods that all these fast-food restaurants offer. She believes that back in the early 1970s, when fast-food companies had not yet existed and home-cooked meals were the only food people had to eat every day, trying to live a healthy life was never a problem.

“A healthful diet typically includes nutrient-dense foods from all major food groups, including lean proteins, whole grains, healthful fats, and fruits and vegetables of many colors. Healthful eating also means replacing foods that contain trans fats, added salt, and sugar with more nutritious options. Following a healthful diet has many health benefits, including building strong bones, protecting the heart, preventing disease, and boosting mood.”

In her essay, Author Cathleen Crichton-Stuart explains the top 10 benefits of eating healthy foods – all of which are medically reviewed by Adrienne Seitz, a registered and licensed dietitian nutritionist. She also gives her readers some quick tips for a healthful diet.

“In today’s generation, healthy and unhealthy food plays a big role in youths and adults. Many people don’t really understand the difference between healthy and unhealthy foods, many don’t actually know what the result of eating too many unhealthy foods can do to the body. There are big differences between eating healthy food, unhealthy food and what the result of excessively eating them can do to the body. In the ongoing battle of “healthy vs. unhealthy foods”, unhealthy foods have their own advantage.”

Author Jaime Padilla compares the difference between healthy food and junk food so that the readers would understand what the result of eating a lot of unhealthy foods can do to the body. He also said that homemade meals are healthier and cheaper than the unhealthy and pricey meals that you order in your local fast food restaurant, which would probably cost you twice as much.

“The Covid-19 pandemic has sparked both an increased clinical and public interest in the role of nutrition and health, particularly in supporting immunity. During this time, when people may be highly vulnerable to misinformation, there have been a plethora of media stories against authoritative scientific opinion, suggesting that certain food components and supplements are capable of ‘boosting’ the immune system. It is important to provide evidence-based advice and to ensure that the use of non-evidence-based approaches to ‘boost’ immunity is not considered as an effective alternative to vaccination or other recognized measures.”

Authors Ayela Spiro, a nutrition science manager, and Helena Gibson-Moore, a nutrition scientist, enlighten their readers on the misinformation spreading in this pandemic about specific food components and supplements. They say that there’s no single food or supplement, or magic diet that can boost the immune system alone. However, eating healthy foods (along with the right dietary supplements), being physically active, and getting enough sleep can help boost your immunity.

If you’re writing an essay about eating healthy foods, you have to define what healthy food is. Food is considered healthy if it provides you with the essential nutrients to sustain your body’s well-being and retain energy. Carbohydrates, proteins, fats, vitamins, minerals, and water are the essential nutrients that compose a healthy, balanced diet.

Eating healthy foods is essential for having good health and nutrition – it protects you against many chronic non-communicable diseases, including heart disease, diabetes, and cancer. If you’re writing an essay about eating healthy foods, show your readers the importance of healthy food, and encourage them to start a healthy diet.

Eating healthy foods means eating a variety of food that give you the nutrients that your body needs to function correctly. These nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water. In your essay about eating healthy foods, you can discuss this topic in more detail so that your readers will know why these nutrients are essential.

Eating healthy foods includes consuming the essential nutrients your body requires to function correctly (such as carbohydrates, proteins, fats, vitamins, minerals, and water) while minimizing processed foods, saturated fats, and alcohol. In your essay, let your readers know that eating healthy foods can help maintain the body’s everyday functions, promote optimal body weight, and prevent diseases.

Eating healthy foods comes with many health benefits – from keeping a healthy weight to preventing long-term diseases such as heart disease, stroke, diabetes, and cancer. So if you’re looking for a topic idea for your essay, you can consider the benefits of eating healthy foods to give your readers some useful information, especially for those thinking of starting a healthy diet.

Ever since we were a kid, we have all been told that eating vegetables are good for our health, but why? The answer is pretty simple – vegetables are loaded with the essential nutrients, vitamins, and minerals that our body needs. So, if you’re writing an essay about eating healthy foods, this is an excellent topic to get you started.

Of course, you definitely can! Fresh fruits and vegetables are typically the cheapest options for starting a healthy diet. In your essay about eating healthy foods, you can include some other cheap food options for a healthy diet – this will be very helpful, especially for readers looking to start a healthy diet but only have a limited amount of budget set for their daily food.

Junk food vs Healthy Food

If we look at the scenario today, we see how the fast-food market is increasing at a rapid rate. With the onset of food delivery apps and more, people now like having junk food more. In addition, junk food is also tastier and easier to prepare.

However, just to satisfy our taste buds we are risking our health. You may feel more satisfied after having junk food but that is just the feeling of fullness and nothing else. Consumption of junk food leads to poor concentration. Moreover, you may also get digestive problems as junk food does not have fiber which helps indigestion.

The definition of what constitutes a healthy diet is continually shifting to reflect the evolving understanding of the roles that different foods, essential nutrients, and other food components play in health and disease. A large and growing body of evidence supports that intake of certain types of nutrients, specific food groups, or overarching dietary patterns positively influences health and promotes the prevention of common non-communicable diseases (NCDs). Greater consumption of health-promoting foods and limited intake of unhealthier options are intrinsic to the eating habits of certain regional diets such as the Mediterranean diet or have been constructed as part of dietary patterns designed to reduce disease risk, such as the Dietary Approaches to Stop Hypertension (DASH) or Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets. In comparison with a more traditional Western diet, these healthier alternatives are higher in plant-based foods, including fresh fruits and vegetables, whole grains, legumes, seeds, and nuts and lower in animal-based foods, particularly fatty and processed meats. To better understand the current concept of a “healthy diet,” this review describes the features and supporting clinical and epidemiologic data for diets that have been shown to prevent disease and/or positively influence health. In total, evidence from epidemiological studies and clinical trials indicates that these types of dietary patterns reduce risks of NCDs including cardiovascular disease and cancer.

1. Introduction

Non-communicable diseases (NCDs) such as cardiovascular disease, cancer, chronic respiratory diseases, diabetes, obesity, and cognitive impairment are among the leading causes of death and disability throughout the world, affecting populations in developed as well as developing countries [ 1 ]. Although there are established genetic and environmental contributors to NCD risk, modifiable lifestyle-related factors play a large role at the individual level [ 2 , 3 , 4 ]. Dietary choices, for example, contribute to the risk for developing hypertension, hypercholesterolemia, overweight/obesity, and inflammation, which in turn increase the risk for diseases that are associated with significant morbidity and mortality, including cardiovascular disease, diabetes, and cancer [ 5 ]. Indeed, the marked rise in chronic NCDs has a causal link to global dietary patterns that are becoming increasingly Westernized [ 6 ], being characterized by high levels of fatty and processed meats, saturated fats, refined grains, salt, and sugars but lacking in fresh fruits and vegetables.

In recognition of the importance of the diet as a determinant of disease risk, the World Health Organization (WHO) Global Action Plan for the Prevention and Control of Noncommunicable Diseases includes strategies for addressing unhealthy diet patterns among its initiatives directed at reducing behavioral risk factors; the other components comprise physical inactivity, tobacco use, and harmful alcohol use [ 1 ]. Dietary changes recommended by WHO include balancing energy intake, limiting saturated and trans fats and shifting toward consumption of unsaturated fats, increasing intake of fruits and vegetables, and limiting the intake of sugar and salt. Many of these dietary targets naturally occur in regional diets such as the Mediterranean diet [ 7 ] or are included as part of evidence-based diets designed to reduce disease risk, such as the Dietary Approaches to Stop Hypertension (DASH) [ 8 ] or Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) [ 9 ] diets. To better understand the current concept of a “healthy diet”, this narrative review describes the features and supporting clinical and epidemiologic data for diets that align with the general WHO guidance and have been shown to prevent disease and/or positively influence health.

2. Components of a Healthy Diet and Their Benefits

A healthy diet is one in which macronutrients are consumed in appropriate proportions to support energetic and physiologic needs without excess intake while also providing sufficient micronutrients and hydration to meet the physiologic needs of the body [ 10 ]. Macronutrients (i.e., carbohydrates, proteins, and fats) provide the energy necessary for the cellular processes required for daily functioning [ 11 ]. Micronutrients (i.e., vitamins and minerals) are required in comparatively small amounts for normal growth, development, metabolism, and physiologic functioning [ 12 , 13 ].

Carbohydrates are the primary source of energy in the diet and are found in the greatest abundance in grains, fruits, legumes, and vegetables [ 14 ]. In terms of deriving a health benefit, whole grains are preferred over processed grains, the latter having been stripped of germ and bran during the milling process, resulting in lower amounts of fiber and micronutrients [ 15 ]. Meta-analyses of prospective cohort studies have linked increased whole-grain intake to a reduced risk of coronary heart disease, stroke, cardiovascular disease, and cancer, as well as to the decreased risk of mortality due to any cause, cardiovascular disease, cancer, respiratory disease, diabetes, and infectious disease [ 15 , 16 , 17 ]. Fresh fruits and vegetables supply energy as well as dietary fiber, which promotes the feeling of satiety and has positive effects on gastrointestinal function, cholesterol levels, and glycemic control [ 18 ]. In addition, fresh fruits and vegetables are key sources of phytochemicals (e.g., polyphenols, phytosterols, carotenoids), which are bioactive compounds believed to confer many of the health benefits associated with fruit and vegetable consumption [ 19 ]. The mechanistic effects of these various phytochemicals are unclear but include their antioxidative properties, as well as their role in regulating nuclear transcription factors, fat metabolism, and inflammatory mediators. For example, flavonoids have been shown to increase insulin secretion and reduce insulin resistance, suggesting that these phytochemicals provide some benefits in obesity and diabetes [ 20 ]. Additionally, polyphenols interact with gastrointestinal microbiota in a bi-directional manner by enhancing gut bacteria and being metabolized by these bacteria to form more bioactive compounds [ 20 ]. Fruit and vegetable intake has been shown to inversely correlate with the risk of NCDs, including hypertension [ 21 ], cardiovascular disease [ 22 , 23 ], chronic obstructive pulmonary disease [ 24 ], lung cancer [ 25 ], and metabolic syndrome [ 26 ].

Dietary proteins provide a source of energy as well as amino acids, including those that the human body requires but cannot produce on its own (i.e., essential amino acids). Dietary proteins are derived from both animal (meat, dairy, fish, and eggs) and plant (legumes, soya products, grains, nuts, and seeds) sources, with the former considered a richer source due to the array of amino acids, high digestibility, and greater bioavailability [ 27 ]. However, animal-based sources of protein contain saturated fatty acids, which have been linked to cardiovascular disease, dyslipidemia, and certain cancers. Although the mechanisms are unclear, red meat, and processed meat in particular, have been associated with an increased risk of colorectal cancer [ 28 , 29 ]. Animal-derived proteins also increase the dietary acid load, tipping the body’s acid-base balance toward acidosis [ 30 , 31 ]. The increased metabolic acid load has been linked to insulin resistance, impaired glucose homeostasis, and the development of urinary calcium stones [ 30 , 31 ].

Adequate dietary protein intake is important for maintaining lean body mass throughout the life span. In older adults, protein plays an important role in preventing age-related loss of skeletal muscle mass [ 32 ], preserving bone mass, and reducing fracture risk [ 33 ]. For older individuals not obtaining adequate protein from their diets, supplementation with amino acids can improve strength and functional status [ 34 ].

Fats (or lipids) are the primary structural components of cellular membranes and are also sources of cellular energy [ 35 ]. Dietary fats fall into 4 categories: monounsaturated fats, polyunsaturated fats, saturated fats, and trans fats. The fat content of food is generally an admixture of these different types [ 35 ]. Unsaturated fats are found in a variety of foods, including fish, many plant-derived oils, nuts, and seeds, whereas animal products (and some plant-derived oils) contribute a larger proportion of saturated fats [ 35 , 36 ]. Trans fats found in foods are predominantly the result of processing vegetable oils but are also present in small quantities in animal products (i.e., ruminant trans fats from cows, sheep, and goats) [ 35 , 36 ]. Among the types of dietary fats, unsaturated fats are associated with reduced cardiovascular and mortality risks, whereas trans fats and, to a lesser degree, saturated fats are associated with negative impacts on health, including increased mortality risk [ 36 , 37 ]. Two families of polyunsaturated fatty acids, omega-3 and omega-6, are described as essential fatty acids, because they are required for normal growth and reproduction but are not produced by the body and, therefore, must be obtained from dietary sources [ 10 ]. Omega-3 fatty acids, in particular, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), have been widely studied for their potential health benefits, with evidence suggesting positive effects including cardioprotection, preventing cognitive decline, reducing inflammation, sustaining muscle mass, and improving systemic insulin resistance [ 38 , 39 , 40 ]. Seafood, especially oily fish, provides EPA and DHA, and supplements are widely available for those not meeting recommended intakes with diet alone [ 41 , 42 ]. Nuts and some seeds and plant oils provide alpha-linolenic acid, the major plant omega-3 fatty acid [ 43 ].

Although required in trace amounts compared with macronutrients, micronutrients are necessary for normal growth, metabolism, physiologic functioning, and cellular integrity [ 12 , 13 ]. The shift from whole foods to processed, refined foods has reduced the micronutrient quality of the modern Western diet [ 44 ]. Vitamin and mineral inadequacies have been implicated in cellular aging and late-onset disease, as scarcity drives chronic metabolic disruption. Keeping with these observations, adequate dietary intake of, or supplementation with, micronutrients that have antioxidant properties (e.g., vitamins A, C, and E, copper, zinc, and selenium) has been suggested as a means to reduce the risk for and progression of age-related diseases [ 45 ].

Water is the principal component of the body, constituting the majority of lean body mass and total body weight [ 13 ]. Water not only provides hydration but also carries micronutrients, including trace elements and electrolytes [ 46 , 47 ]. Drinking water may supply as much as 20% of the daily recommended intake of calcium and magnesium [ 47 ]. Our understanding of water requirements and water’s effect on health and disease is limited, although the global increase in intake of high-calorie beverages has refocused attention on the importance of water for maintaining health and preventing disease [ 46 ].

3. Common Health-Promoting Dietary Patterns

Based on our understanding of nutritional requirements and their likely health impacts as described above, healthy dietary patterns can be generally described as those that are rich in health-promoting foods, including plant-based foods, fresh fruits and vegetables, antioxidants, soya, nuts, and sources of omega-3 fatty acids, and low in saturated fats and trans fats, animal-derived proteins, and added/refined sugars [ 48 ]. Patterns such as these are naturally occurring in certain regions of the world and rooted in local/regional tradition and food sources, as is the case for the traditional Mediterranean and Asian diets. Healthy dietary patterns have also been developed based on studies of nutrient intake and subsequent health measures or outcomes (e.g., the DASH [ 8 ] and MIND [ 9 ] diets) that share some common characteristics ( Figure 1 ).

3.1. Mediterranean Diet

The Mediterranean diet is based on components of the traditional dietary patterns of Euro-Mediterranean countries and encompasses not only the types of foods consumed and their relative contributions to daily nutrient intake, but also an approach to eating that is cognizant of how foods are sourced (e.g., sustainability and eco-friendliness), cooked, and eaten, as well as lifestyle considerations such as engaging in regular physical activity, getting adequate rest, and participating in fellowship when preparing and sharing meals [ 7 ]. Within the core framework of the Mediterranean diet, variations based on geography and culture are reflected in the emphasis on the inclusion of traditional and local food products. The primary basis of daily meals in the Mediterranean diet is cereals such as whole-grain bread, pastas, couscous, and other unrefined grains that are rich in fiber and a variety of fruits and vegetables of different colors and textures that are high in micronutrients, fiber, and phytochemicals ( Table 1 ) [ 7 , 9 , 49 , 50 , 51 , 52 ]. Dairy products, preferably low-fat yogurt, cheese, or other fermented dairy products, are recommended daily in moderation as a source of calcium, which is needed for bone and heart health. Olive oil serves as the primary source of dietary lipids and is supplemented with olives, nuts, and seeds. Water (1.5–2.0 L/day or ~8 glasses) is recommended as the main source of hydration, whereas wine and other fermented alcoholic beverages are generally permitted in moderation, to be consumed with meals. Fish, white meat, and eggs are the primary sources of protein; red meat and processed meats are consumed less frequently and in smaller portions. Legumes are also a preferred source of plant-based proteins [ 7 ].

Comparison of nutritional/lifestyle components among different healthy diet options.

a Recommendations shown here are based on a 2000 calorie per day eating plan. b Contribution of total fat and quality of fat from cheese to stay within the recommended daily intake.

The health benefits of the Mediterranean diet were first described in 1975 by Ancel Keys, who observed a reduction in cardiovascular disease risk among populations whose nutritional model was consistent with practices of peoples from the Mediterranean Basin [ 53 ]. Since that time, research has revealed beneficial effects of the Mediterranean diet on a number of NCDs and related health measures, including cardiovascular and cerebrovascular disease [ 54 ], cancer [ 55 ], glycemic control [ 56 ], and cognitive function [ 57 , 58 ]. Although publication of a key intervention study (Prevención con Dieta Mediterránea; PREDIMED) conducted at multiple sites across Spain and evaluating the Mediterranean diet for the primary prevention of cardiovascular disease was retracted due to irregularities in randomization [ 59 ], a subsequent analysis adjusting for these issues reported a consistent positive effect of adhering to a Mediterranean diet supplemented with olive oil or nuts compared with a reduced-fat diet [ 59 ]. Substudies of PREDIMED have also shown that, compared with a low-fat control diet, the Mediterranean diet supplemented with olive oil or nuts is associated with a 30% reduced risk of major cardiovascular risk events [ 59 ] and reductions in systolic blood pressure (SBP) and diastolic blood pressure (DBP) of 5.8–7.3 mmHg and 3.3–3.4 mmHg, respectively [ 60 ]. In addition, cardiovascular factors such as mean internal carotid artery intima-media thickness (−0.084 mm; p < 0.05) and maximum plaque height (−0.091 mm; p < 0.05) are improved with the Mediterranean diet supplemented with nuts [ 61 ]. Greater intake of polyphenols (phytochemicals found in fruits, vegetables, tea, olive oil, and wine) correlated with a 36% reduced risk of hypertension ( p = 0.015) [ 62 ] and improvements in inflammatory biomarkers related to atherosclerosis (i.e., interleukin [IL]-6, tumor necrosis factor-alpha, soluble intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and monocyte chemotactic protein-1; p < 0.05 for each), as well as in high-density lipoprotein cholesterol (HDL-C; p = 0.004) [ 62 , 63 ].

3.2. Dietary Approaches to Stop Hypertension (DASH)

The DASH diet derives its name from the Dietary Approaches to Stop Hypertension study, which evaluated the influence of dietary patterns on blood pressure [ 8 ]. Patients who consumed a diet that was rich in fruits, vegetables, and low-fat dairy and that included a reduced amount of saturated and total fat and cholesterol experienced significantly greater reductions in blood pressure than patients who consumed a control diet that was similar in composition to a typical American diet (difference in SBP/DBP, −5.5/−3.0 mmHg; p < 0.001) or a diet rich in fruits and vegetables with a reduced amount of snacks and sweets (−2.7/−1.9 mmHg; p ≤ 0.002). All 3 diets had a sodium content of 3 g per day. A subsequent study (DASH-Sodium) that explored the DASH diet or a control diet in combination with varying levels of sodium intake (high, intermediate, and low) found that the DASH diet significantly reduced SBP during the high, intermediate, and low sodium intake phases of both diets (high: −5.9 mmHg; p < 0.001; intermediate: −5.0 mmHg; p < 0.001; low: −2.2 mmHg; p < 0.05) [ 64 ]. The DASH diet also significantly reduced DBP versus the control diet during the high (−2.9 mmHg; p < 0.001) and intermediate (−2.5 mmHg; p < 0.01) sodium intake phases but not during the low intake phase (−1.0 mmHg). Although reducing sodium intake also significantly reduced blood pressure in the control diet group ( p < 0.05), the low sodium phase of the DASH diet elicited significant decreases in SBP/DBP of −8.9/−4.5 mmHg ( p < 0.001 for each) compared with high sodium intake phase of the control diet.

Subsequent controlled trials, as a whole, support the results of the DASH and DASH-Sodium studies in terms of blood pressure reduction. Moreover, these studies expanded the positive impacts of the DASH diet to include improvements in other cardiovascular risk factors or comorbidities (e.g., low-density lipoprotein cholesterol [LDL-C], total cholesterol, overweight/obesity, and insulin sensitivity) [ 65 , 66 , 67 , 68 ] and reductions in adverse outcomes such as development of cardiovascular disease, coronary heart disease, stroke, heart failure, metabolic syndrome, and diabetes (including improved pregnancy outcomes in women with gestational diabetes) [ 68 , 69 , 70 , 71 , 72 ]. Meta-analyses of studies using the DASH diet have demonstrated that LDL-C is significantly reduced by −0.1 mmol/L ( p = 0.03) [ 65 , 68 ], total cholesterol by −0.2 mmol/L ( p < 0.001) [ 65 , 68 ], body weight by −1.42 kg ( p < 0.001) [ 66 , 68 ], and fasting insulin by −0.15 μU/mL ( p < 0.001) [ 65 , 66 , 67 , 68 ]. With the DASH diet, the risk of cardiovascular disease is reduced by 20%, stroke by 19%, and heart failure by 29% ( p < 0.001 for each) [ 69 , 71 ]. The overall risk of diabetes is reduced by 18% [ 68 ], and children and adolescents with higher DASH scores (i.e., those whose diets included the highest intakes of fruits, vegetables, nuts, legumes, low-fat dairy, and whole grains) were at 64% lower risk of developing metabolic syndrome than those with the lowest DASH scores ( p = 0.023) [ 71 ]. Furthermore, rates of cesarean section decreased by 47% [ 72 ], incidence of macrosomia (birth weight > 4000 g) decreased from 39% to 4% ( p = 0.002) [ 70 ], and significantly fewer women experienced gestational diabetes that required insulin therapy on the DASH diet (23%) compared with the control diet (73%; p < 0.0001) [ 70 ].

The dietary pattern derived from the DASH study emphasizes the consumption of an array of vegetables (including colorful varieties, legumes, and starchy vegetables), fruits, fat-free or low-fat dairy products, whole grains, and various protein sources (e.g., seafood, lean meats, eggs, legumes, nuts, seeds, and soya) ( Table 1 ) [ 49 ]. Limited consumption of added sugars (< 10% of calories per day), saturated fats (< 10% of calories per day), sodium (< 2300 mg/day), and alcohol (≤ 1 drink per day for women and ≤ 2 drinks per day for men) is suggested. In addition, further reductions in blood pressure may be achievable by further reducing sodium intake, although practical challenges may limit the ability to achieve sodium intake of 1200 mg or less per day [ 49 ].

3.3. Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND)

The MIND diet combines elements of the Mediterranean and DASH diets with the goal of sustaining cognitive health throughout older age [ 9 ]. Both the Mediterranean and DASH diets have been individually linked to positive cognitive outcomes, including the prevention of cognitive decline or impairment and better cognitive performance [ 73 , 74 , 75 ]. Two high-quality cohort studies have reported associations between adherence to the MIND diet and a 53% lower risk for developing Alzheimer’s disease ( p = 0.002 for linear trend) [ 50 ] and slower declines in cognitive functioning, both overall and within specific cognitive domains (e.g., episodic, semantic, and working memory and perceptual speed and organization), such that the highest adherence rates to the MIND diet were associated with cognitive function equivalent to being 7.5 years younger [ 50 , 76 ]. Interestingly, even modest adherence to the MIND diet was associated with a 35% risk reduction for Alzheimer’s disease versus the lowest adherence group ( p = 0.002 for linear trend), whereas high adherence was needed to demonstrate 54% and 39% risk reductions with the Mediterranean and DASH diets, respectively; high adherence to the Mediterranean and DASH diet showed a statistically significant benefit [ 50 ].

The MIND diet focuses on increasing the intake of fresh fruits and vegetables and emphasizes brain-healthy foods such as green leafy vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil, and wine in moderation ( Table 1 ) [ 9 , 50 ]. Additionally, foods that are thought to be unhealthy for the brain, such as red meats, butter/margarine, cheese, pastries, sweets, and fried or fast food, are limited [ 9 ]. The specificity regarding the types of foods on the healthy and unhealthy lists differentiates MIND from the Mediterranean or DASH diets [ 50 ].

3.4. Nordic Diet

Iterations of a Nordic diet (e.g., the healthy Nordic diet, New Nordic Diet) arose from the desire to translate the Mediterranean, DASH, and other health-promoting diets into a regionally tailored dietary pattern that uses traditional, local Nordic foods and would be attractive to the public, sustainable, and eco-friendly [ 77 , 78 ]. Overarching tenets of the New Nordic Diet are to consume more (1) calories from plant sources and fewer from animal sources, (2) foods from seas and lakes, and (3) foods from the wild countryside [ 78 , 79 ]. A generalized Nordic dietary pattern would include green leafy vegetables, other vegetables, fruits, fish and seafood, potatoes, berries, whole grains (e.g., wheat, rye, oats, barley), nuts, low-fat dairy products, rapeseed, sunflower, and/or soya oils and limited intake of fresh red meat and sugar [ 78 , 80 ]. Specific dietary recommendations based on the NORDIET clinical trial are presented in Table 1 [ 51 ].

The randomized, controlled NORDIET study compared a healthy Nordic diet with a control diet (the participant’s usual Western diet) [ 77 ]. Over 6 weeks, the Nordic diet improved the lipid profile (including a 0.98 mmol/L reduction in total cholesterol [ p < 0.0001] and a 0.83 mmol/L reduction in LDL-C [ p < 0.001]), lowered SBP by 6.6 mmHg ( p = 0.008), and improved insulin sensitivity (homeostatic model assessment-insulin resistance decreased 0.11; p = 0.01) compared with the control diet. Those on the Nordic diet also experienced a 3.0 kg decrease in body weight ( p < 0.001) despite food being available ad libitum.

Results from subsequent studies conducted using Nordic diet variations are consistent with those from studies with the NORDIET study, demonstrating improvements relative to the control diet in blood lipid profile (LDL-C/HDL-C ratio, −0.15; p = 0.046) [ 81 ], inflammation (IL-1 receptor antagonist, −84 ng/L; p < 0.001) [ 81 ], blood pressure (DBP, −4.4 mmHg ( p = 0.001), and mean arterial pressure (−4.2 mmHg; p = 0.006) among patients with metabolic syndrome [ 82 ] and weight loss (−3.22 kg; p < 0.001) [ 83 ] and blood pressure reduction (SBP/DBP, −5.13/−3.24 mmHg; p < 0.05) in individuals with obesity [ 83 ]. Compared with baseline values, one study demonstrated blood pressure reductions of −6.9 mmHg (SBP) and −3.2 mmHg (DBP; p < 0.01) [ 83 , 84 ]. Additionally, a study conducted in children reported an improvement in omega-3 fatty acid status with the Nordic diet that was associated with improvements in school performance ( p < 0.05) [ 85 ]. A systematic review parsing the individual components of the Nordic diet found that evidence supported the protective effects of eating whole grains on type 2 diabetes and cardiovascular disease risk, but that there was insufficient evidence for other foods in the Nordic diet [ 86 ].

3.5. Traditional Asian Diets

Although there is substantial evidence supporting the Mediterranean and other European-based diets, traditional regional dietary patterns from other parts of the world that follow similar principles have less–well-established links to positive health outcomes. A full description of the breadth of regional diets and the associated evidence bases is beyond the scope of this publication, but we consider some Asian-based diets to be particularly relevant to this discussion.

The traditional Korean diet is composed of rice and other whole grains, fermented food, indigenous land and sea vegetables, proteins primarily from legumes and fish as opposed to red meat, medicinal herbs (e.g., garlic, green onions, ginger), and sesame and perilla oils [ 87 ]. Meals typically consist of multiple small-portion dishes are often derived from seasonal food sources and are home-cooked. Unlike the Western diet, the traditional Korean diet does not include many fried foods [ 87 ]. Epidemiologic data suggest a reduced risk of metabolic syndrome (odds ratio [OR]: 0.77; 95% CI: 0.60–0.99), obesity (OR: 0.72; 95% CI: 0.55–0.95), hypertension (OR: 0.74; 95% CI: 0.57–0.98), and hypertriglyceridemia (OR: 0.76; 95% CI: 0.59–0.99) among individuals who follow traditional Korean dietary patterns [ 88 ]. These findings are consistent with a controlled clinical trial that explored the effects of a traditional Korean diet compared with a control diet (“eat as usual”) on cardiovascular risk factors in patients with diabetes and hypertension. In that study, adherence to a traditional Korean diet favorably influenced body composition (body weight, −2.3 kg; body mass index [BMI], −0.83 kg/m 2 ; body fat, −2.2%; p < 0.01), heart rate (−7.1 bpm; p = 0.002), and glycemic control (HbA1c, −0.72%; p = 0.003) [ 89 ].

The traditional Chinese diet features rice or noodles, soups, vegetables, steamed breads or dumplings, fruits and vegetables, soy, seafood, and meat [ 90 , 91 ]. Although higher in carbohydrates and lower in fat compared with a Western diet, the traditional Chinese diet does not appear to promote weight gain in healthy, normal-weight Chinese, suggesting that carbohydrate restriction may not be a universally applicable intervention to combat obesity and cardiometabolic risk [ 92 ]. One 6-week controlled trial demonstrated that 52% of non-Chinese individuals with overweight or obesity who adhered to a traditional Chinese diet had a reduction in BMI while preserving lean body mass compared with 28% of those who followed a Western diet at the 1-year follow-up assessment [ 93 ]. In another trial, BMI decreased by 0.37 kg/m 2 and lean mass by 0.21 kg among subjects who adhered to a traditional Chinese diet for 6 weeks, whereas those who followed a Western diet had 0.26 kg/m 2 and 0.49 kg reductions in BMI and lean body mass, respectively [ 94 ]. Notably, both of these studies restricted caloric intake to 1,200 Kcal for the test and control diet groups.

Similar to the Korean diet, the traditional Japanese diet (known as Washoku) is characterized by small portions of multiple components, primarily including rice, fish (often eaten raw), soups, and pickles [ 95 ]. Fermented soybean paste (dashi) serves as the base of many of the soups that are central to the traditional Japanese diet; other ingredients include seaweed, fruits and vegetables, and mushrooms. The use of chopsticks, alternating between dishes of small portion size throughout a meal, and the base flavor of Japanese food (umami) enhance satiety and help to prevent overeating. Adherence to a traditional Japanese dietary pattern has been associated with favorable effects on blood pressure among apparently healthy Japanese adults [ 96 ]. This is consistent with data from the 2012 Japan National Health and Nutrition Survey demonstrating that adherence to a traditional Japanese diet compared with a Western diet or a meat- and fat-based dietary pattern was associated with a lower prevalence of hypertension in men [ 97 ]. However, in the same study, a traditional Japanese diet was associated with higher DBP in women, as well as higher waist circumference and BMI in men. Further study is needed to elucidate the health impacts of traditional Japanese and other Asian dietary patterns.

4. Additional Factors

While the evidence reviewed here suggests that the described dietary patterns positively influence measures of health and disease risk and outcome because they encourage the intake of foods that individually have beneficial effects and the avoidance of unhealthy options, additional factors combine to create a lifestyle that promotes health. For example, healthy diets include adequate hydration, typically in the form of water or tea/herbal infusions [ 7 , 49 , 51 , 52 ]. In addition to the dietary components, a healthy lifestyle is one that incorporates regular exercise, socialization, and adequate sleep [ 7 , 52 ], and minimizes elements that have a negative effect on health such as tobacco use, excessive alcohol consumption, physical inactivity, large amounts of screen time, and stress.

The importance of non-dietary factors is reflected in their inclusion in modern food pyramids. Built on a base of positive lifestyle factors, the lower tiers indicate daily consumption of adequate hydration and nutrient-rich, plant-based foods, with animal-derived products (meat, fish, and dairy) and sweets comprising higher tiers of the pyramid (i.e., less frequently or infrequently consumed items).

Whereas the goal may be to achieve nutrient requirements through food and water intake alone, there are situations in which food-derived nutrient intake might be inadequate due to increased need, selective eating, or food insecurity/limited access to more nutritious foods [ 98 , 99 , 100 ]. Therefore, for some individuals, dietary supplements may be required, particularly at certain life phases. For example, later in life, the recommended intake of calcium increases to sustain bone mineral density [ 101 ]; hence, supplementation with calcium may be necessary to meet recommended intake levels in older adults. Before initiating supplementation, dietary intake levels should be considered to avoid exceeding the upper tolerability limits and causing adverse events.

There are a number of other traditional regional diets that likely have similar benefits to those that we describe here. However, we made the decision to narrow our focus to those diets with evidence from randomized, controlled trials demonstrating their health benefits. For example, the African Heritage Diet focuses on traditional ingredients that may be beneficial to African American populations who experience disproportionately higher risks for chronic diseases related to their diets [ 102 ]. Future research is warranted to evaluate the impact of the African Heritage Diet and other regional dietary patterns on health.

5. Conclusions

Healthy diets, arising either by tradition or design, share many common features and generally align with the WHO Global Action Plan for the Prevention and Control of Noncommunicable Diseases. In comparison with a Western diet, these healthier alternatives are higher in plant-based foods, including fresh fruits and vegetables, whole grains, legumes, seeds, and nuts and lower in animal-based foods, particularly fatty and processed meats. Evidence from epidemiologic studies and clinical trials indicates that these types of dietary patterns reduce risks of NCDs ranging from cardiovascular disease to cancer. Further endeavors are needed to integrate these healthy dietary and lifestyle choices into daily living in communities throughout the world and to make healthy eating accessible, achievable, and sustainable.

Introduction

In this argumentative research essay for a first-year composition class, student Lily Tran creates a solid, focused argument and supports it with researched evidence. Throughout the essay, she uses this evidence to support cause-and-effect and problem-solution reasoning, make strong appeals, and develop her ethos on the topic.

Living by Their Own Words

Food as change.

public domain text For the human race to have a sustainable future, massive changes in the way food is produced, processed, and distributed are necessary on a global scale. end public domain text

annotated text Purpose. Lily Tran refers to what she sees as the general purpose for writing this paper: the problem of current global practices in food production, processing, and distribution. By presenting the “problem,” she immediately prepares readers for her proposed solution. end annotated text

public domain text The required changes will affect nearly all aspects of life, including not only world hunger but also health and welfare, land use and habitats, water quality and availability, energy use and production, greenhouse gas emissions and climate change, economics, and even cultural and social values. These changes may not be popular, but they are imperative. The human race must turn to sustainable food systems that provide healthy diets with minimal environmental impact—and starting now. end public domain text

annotated text Thesis. Leading up to this clear, declarative thesis statement are key points on which Tran will expand later. In doing this, she presents some foundational evidence that connects the problem to the proposed solution. end annotated text

THE COMING FOOD CRISIS

public domain text The world population has been rising exponentially in modern history. From 1 billion in 1804, it doubled to approximately 2 billion by 1927, then doubled again to approximately 4 billion in 1974. By 2019, it had nearly doubled again, rising to 7.7 billion (“World Population by Year”). It has been projected to reach nearly 10 billion by 2050 (Berners-Lee et al.). At the same time, the average life span also has been increasing. These situations have led to severe stress on the environment, particularly in the demands for food. It has been estimated, for example, that by 2050, milk production will increase 58 percent and meat production 73 percent (Chai et al.). end public domain text

annotated text Evidence. In this first supporting paragraph, Tran uses numerical evidence from several sources. This numerical data as evidence helps establish the projection of population growth. By beginning with such evidence, Tran underscores the severity of the situation. end annotated text

public domain text Theoretically, the planet can produce enough food for everyone, but human activities have endangered this capability through unsustainable practices. Currently, agriculture produces 10–23 percent of global greenhouse gas emissions. Greenhouse gases—the most common being carbon dioxide, methane, nitrous oxide, and water vapor— trap heat in the atmosphere, reradiate it, and send it back to Earth again. Heat trapped in the atmosphere is a problem because it causes unnatural global warming as well as air pollution, extreme weather conditions, and respiratory diseases. end public domain text

annotated text Audience. With her audience in mind, Tran briefly explains the problem of greenhouse gases and global warming. end annotated text

public domain text It has been estimated that global greenhouse gas emissions will increase by as much as 150 percent by 2030 (Chai et al.). Transportation also has a negative effect on the environment when foods are shipped around the world. As Joseph Poore of the University of Oxford commented, “It’s essential to be mindful about everything we consume: air-transported fruit and veg can create more greenhouse gas emissions per kilogram than poultry meat, for example” (qtd. in Gray). end public domain text

annotated text Transition. By beginning this paragraph with her own transition of ideas, Tran establishes control over the organization and development of ideas. Thus, she retains her sources as supports and does not allow them to dominate her essay. end annotated text

public domain text Current practices have affected the nutritional value of foods. Concentrated animal-feeding operations, intended to increase production, have had the side effect of decreasing nutritional content in animal protein and increasing saturated fat. One study found that an intensively raised chicken in 2017 contained only one-sixth of the amount of omega-3 fatty acid, an essential nutrient, that was in a chicken in 1970. Today the majority of calories in chicken come from fat rather than protein (World Wildlife Fund). end public domain text

annotated text Example. By focusing on an example (chicken), Tran uses specific research data to develop the nuance of the argument. end annotated text

public domain text Current policies such as government subsidies that divert food to biofuels are counterproductive to the goal of achieving adequate global nutrition. Some trade policies allow “dumping” of below-cost, subsidized foods on developing countries that should instead be enabled to protect their farmers and meet their own nutritional needs (Sierra Club). Too often, agriculture’s objectives are geared toward maximizing quantities produced per acre rather than optimizing output of critical nutritional needs and protection of the environment. end public domain text

AREAS OF CONCERN

Hunger and nutrition.

annotated text Headings and Subheadings. Throughout the essay, Tran has created headings and subheadings to help organize her argument and clarify it for readers. end annotated text

public domain text More than 820 million people around the world do not have enough to eat. At the same time, about a third of all grains and almost two-thirds of all soybeans, maize, and barley crops are fed to animals (Barnard). According to the World Health Organization, 462 million adults are underweight, 47 million children under 5 years of age are underweight for their height, 14.3 million are severely underweight for their height, and 144 million are stunted (“Malnutrition”). About 45 percent of mortality among children under 5 is linked to undernutrition. These deaths occur mainly in low- and middle-income countries where, in stark contrast, the rate of childhood obesity is rising. Globally, 1.9 billion adults and 38.3 million children are overweight or obese (“Obesity”). Undernutrition and obesity can be found in the same household, largely a result of eating energy-dense foods that are high in fat and sugars. The global impact of malnutrition, which includes both undernutrition and obesity, has lasting developmental, economic, social, and medical consequences. end public domain text

public domain text In 2019, Berners-Lee et al. published the results of their quantitative analysis of global and regional food supply. They determined that significant changes are needed on four fronts: end public domain text

Food production must be sufficient, in quantity and quality, to feed the global population without unacceptable environmental impacts. Food distribution must be sufficiently efficient so that a diverse range of foods containing adequate nutrition is available to all, again without unacceptable environmental impacts. Socio-economic conditions must be sufficiently equitable so that all consumers can access the quantity and range of foods needed for a healthy diet. Consumers need to be able to make informed and rational choices so that they consume a healthy and environmentally sustainable diet (10).

annotated text Block Quote. The writer has chosen to present important evidence as a direct quotation, using the correct format for direct quotations longer than four lines. See Section Editing Focus: Integrating Sources and Quotations for more information about block quotes. end annotated text

public domain text Among their findings, they singled out, in particular, the practice of using human-edible crops to produce meat, dairy, and fish for the human table. Currently 34 percent of human-edible crops are fed to animals, a practice that reduces calorie and protein supplies. They state in their report, “If society continues on a ‘business-as-usual’ dietary trajectory, a 119% increase in edible crops grown will be required by 2050” (1). Future food production and distribution must be transformed into systems that are nutritionally adequate, environmentally sound, and economically affordable. end public domain text

Land and Water Use

public domain text Agriculture occupies 40 percent of Earth’s ice-free land mass (Barnard). While the net area used for producing food has been fairly constant since the mid-20th century, the locations have shifted significantly. Temperate regions of North America, Europe, and Russia have lost agricultural land to other uses, while in the tropics, agricultural land has expanded, mainly as a result of clearing forests and burning biomass (Willett et al.). Seventy percent of the rainforest that has been cut down is being used to graze livestock (Münter). Agricultural use of water is of critical concern both quantitatively and qualitatively. Agriculture accounts for about 70 percent of freshwater use, making it “the world’s largest water-consuming sector” (Barnard). Meat, dairy, and egg production causes water pollution, as liquid wastes flow into rivers and to the ocean (World Wildlife Fund and Knorr Foods). According to the Hertwich et al., “the impacts related to these activities are unlikely to be reduced, but rather enhanced, in a business-as-usual scenario for the future” (13). end public domain text

annotated text Statistical Data. To develop her points related to land and water use, Tran presents specific statistical data throughout this section. Notice that she has chosen only the needed words of these key points to ensure that she controls the development of the supporting point and does not overuse borrowed source material. end annotated text

annotated text Defining Terms. Aware of her audience, Tran defines monocropping , a term that may be unfamiliar. end annotated text

public domain text Earth’s resources and ability to absorb pollution are limited, and many current agricultural practices undermine these capacities. Among these unsustainable practices are monocropping [growing a single crop year after year on the same land], concentrated animal-feeding operations, and overdependence on manufactured pesticides and fertilizers (Hamilton). Such practices deplete the soil, dramatically increase energy use, reduce pollinator populations, and lead to the collapse of resource supplies. One study found that producing one gram of beef for human consumption requires 42 times more land, 2 times more water, and 4 times more nitrogen than staple crops. It also creates 3 times more greenhouse gas emissions (Chai et al.). The EAT– Lancet Commission calls for “halting expansion of new agricultural land at the expense of natural ecosystems . . . strict protections on intact ecosystems, suspending concessions for logging in protected areas, or conversion of remaining intact ecosystems, particularly peatlands and forest areas” (Willett et al. 481). The Commission also calls for land-use zoning, regulations prohibiting land clearing, and incentives for protecting natural areas, including forests. end public domain text

annotated text Synthesis. The paragraphs above and below this comment show how Tran has synthesized content from several sources to help establish and reinforce key supports of her essay . end annotated text

Greenhouse Gas and Climate Change

public domain text Climate change is heavily affected by two factors: greenhouse gas emissions and carbon sequestration. In nature, the two remain in balance; for example, most animals exhale carbon dioxide, and most plants capture carbon dioxide. Carbon is also captured, or sequestered, by soil and water, especially oceans, in what are called “sinks.” Human activities have skewed this balance over the past two centuries. The shift in land use, which exploits land, water, and fossil energy, has caused increased greenhouse-gas emissions, which in turn accelerate climate change. end public domain text

public domain text Global food systems are threatened by climate change because farmers depend on relatively stable climate systems to plan for production and harvest. Yet food production is responsible for up to 30 percent of greenhouse gas emissions (Barnard). While soil can be a highly effective means of carbon sequestration, agricultural soils have lost much of their effectiveness from overgrazing, erosion, overuse of chemical fertilizer, and excess tilling. Hamilton reports that the world’s cultivated and grazed soils have lost 50 to 70 percent of their ability to accumulate and store carbon. As a result, “billions of tons of carbon have been released into the atmosphere.” end public domain text

annotated text Direct Quotation and Paraphrase. While Tran has paraphrased some content of this source borrowing, because of the specificity and impact of the number— “billions of tons of carbon”—she has chosen to use the author’s original words. As she has done elsewhere in the essay, she has indicated these as directly borrowed words by placing them within quotation marks. See Section 12.5 for more about paraphrasing. end annotated text

public domain text While carbon sequestration has been falling, greenhouse gas emissions have been increasing as a result of the production, transport, processing, storage, waste disposal, and other life stages of food production. Agriculture alone is responsible for fully 10 to 12 percent of global emissions, and that figure is estimated to rise by up to 150 percent of current levels by 2030 (Chai et al.). Münter reports that “more greenhouse gas emissions are produced by growing livestock for meat than all the planes, trains, ships, cars, trucks, and all forms of fossil fuel-based transportation combined” (5). Additional greenhouse gases, methane and nitrous oxide, are produced by the decomposition of organic wastes. Methane has 25 times and nitrous oxide has nearly 300 times the global warming potential of carbon dioxide (Curnow). Agricultural and food production systems must be reformed to shift agriculture from greenhouse gas source to sink. end public domain text

Social and Cultural Values

public domain text As the Sierra Club has pointed out, agriculture is inherently cultural: all systems of food production have “the capacity to generate . . . economic benefits and ecological capital” as well as “a sense of meaning and connection to natural resources.” Yet this connection is more evident in some cultures and less so in others. Wealthy countries built on a consumer culture emphasize excess consumption. One result of this attitude is that in 2014, Americans discarded the equivalent of $165 billion worth of food. Much of this waste ended up rotting in landfills, comprised the single largest component of U.S. municipal solid waste, and contributed a substantial portion of U.S. methane emissions (Sierra Club). In low- and middle-income countries, food waste tends to occur in early production stages because of poor scheduling of harvests, improper handling of produce, or lack of market access (Willett et al.). The recent “America First” philosophy has encouraged prioritizing the economic welfare of one nation to the detriment of global welfare and sustainability. end public domain text

annotated text Synthesis and Response to Claims. Here, as in subsequent sections, while still relying heavily on facts and content from borrowed sources, Tran provides her synthesized understanding of the information by responding to key points. end annotated text

public domain text In response to claims that a vegetarian diet is a necessary component of sustainable food production and consumption, Lusk and Norwood determined the importance of meat in a consumer’s diet. Their study indicated that meat is the most valuable food category to consumers, and “humans derive great pleasure from consuming beef, pork, and poultry” (120). Currently only 4 percent of Americans are vegetarians, and it would be difficult to convince consumers to change their eating habits. Purdy adds “there’s the issue of philosophy. A lot of vegans aren’t in the business of avoiding animal products for the sake of land sustainability. Many would prefer to just leave animal husbandry out of food altogether.” end public domain text

public domain text At the same time, consumers expect ready availability of the foods they desire, regardless of health implications or sustainability of sources. Unhealthy and unsustainable foods are heavily marketed. Out-of-season produce is imported year-round, increasing carbon emissions from air transportation. Highly processed and packaged convenience foods are nutritionally inferior and waste both energy and packaging materials. Serving sizes are larger than necessary, contributing to overconsumption and obesity. Snack food vending machines are ubiquitous in schools and public buildings. What is needed is a widespread attitude shift toward reducing waste, choosing local fruits and vegetables that are in season, and paying attention to how foods are grown and transported. end public domain text

annotated text Thesis Restated. Restating her thesis, Tran ends this section by advocating for a change in attitude to bring about sustainability. end annotated text

DISSENTING OPINIONS

annotated text Counterclaims . Tran uses equally strong research to present the counterargument. Presenting both sides by addressing objections is important in constructing a clear, well-reasoned argument. Writers should use as much rigor in finding research-based evidence to counter the opposition as they do to develop their argument. end annotated text

public domain text Transformation of the food production system faces resistance for a number of reasons, most of which dispute the need for plant-based diets. Historically, meat has been considered integral to athletes’ diets and thus has caused many consumers to believe meat is necessary for a healthy diet. Lynch et al. examined the impact of plant-based diets on human physical health, environmental sustainability, and exercise performance capacity. The results show “it is unlikely that plant-based diets provide advantages, but do not suffer from disadvantages, compared to omnivorous diets for strength, anaerobic, or aerobic exercise performance” (1). end public domain text

public domain text A second objection addresses the claim that land use for animal-based food production contributes to pollution and greenhouse gas emissions and is inefficient in terms of nutrient delivery. Berners-Lee et al. point out that animal nutrition from grass, pasture, and silage comes partially from land that cannot be used for other purposes, such as producing food directly edible by humans or for other ecosystem services such as biofuel production. Consequently, nutritional losses from such land use do not fully translate into losses of human-available nutrients (3). end public domain text

annotated text Paraphrase. Tran has paraphrased the information as support. Though she still cites the source, she has changed the words to her own, most likely to condense a larger amount of original text or to make it more accessible. end annotated text

public domain text While this objection may be correct, it does not address the fact that natural carbon sinks are being destroyed to increase agricultural land and, therefore, increase greenhouse gas emissions into the atmosphere. end public domain text

public domain text Another significant dissenting opinion is that transforming food production will place hardships on farmers and others employed in the food industry. Farmers and ranchers make a major investment in their own operations. At the same time, they support jobs in related industries, as consumers of farm machinery, customers at local businesses, and suppliers for other industries such as food processing (Schulz). Sparks reports that “livestock farmers are being unfairly ‘demonized’ by vegans and environmental advocates” and argues that while farming includes both costs and benefits, the costs receive much more attention than the benefits. end public domain text

FUTURE GENERATIONS

public domain text The EAT– Lancet Commission calls for a transformation in the global food system, implementing different core processes and feedback. This transformation will not happen unless there is “widespread, multi-sector, multilevel action to change what food is eaten, how it is produced, and its effects on the environment and health, while providing healthy diets for the global population” (Willett et al. 476). System changes will require global efforts coordinated across all levels and will require governments, the private sector, and civil society to share a common vision and goals. Scientific modeling indicates 10 billion people could indeed be fed a healthy and sustainable diet. end public domain text

annotated text Conclusion. While still using research-based sources as evidence in the concluding section, Tran finishes with her own words, restating her thesis. end annotated text

public domain text For the human race to have a sustainable future, massive changes in the way food is produced, processed, and distributed are necessary on a global scale. The required changes will affect nearly all aspects of life, including not only world hunger but also health and welfare, land use and habitats, water quality and availability, energy use and production, greenhouse gas emissions and climate change, economics, and even cultural and social values. These changes may not be popular, but they are imperative. They are also achievable. The human race must turn to sustainable food systems that provide healthy diets with minimal environmental impact, starting now. end public domain text

annotated text Sources. Note two important aspects of the sources chosen: 1) They represent a range of perspectives, and 2) They are all quite current. When exploring a contemporary topic, it is important to avoid research that is out of date. end annotated text

Dietary Consumption: Strategies for Healthy Eating Essay (Speech)

General Goal: To persuade.

Specific Goal: At the end of my speech, the audience will be able to differentiate between healthy and unhealthy eating.

Central Idea: People should incorporate healthy eating in their diets contrary to which it increases the risk of developing various diseases.

Introduction

A report by the Centers for Disease Control and Prevention (CDC) indicate that, while eating nutritious food is essential for enhancing your health, most people consume an unhealthy diet thus increasing the risk of contracting various diseases such as cancer, reduced brain functioning, type 2 diabetes, stroke, heart disease, or being generally obese or overweight (CDC, 2021a). Most people fall into this category, not because they lack the knowledge about healthy eating, but because they chose to ignore the recommended nutritious consumption.

Reveal Your Topic

Today, I will highlight some strategies of healthy eating against which failure to follow them would be detrimental to your health.

Motivate the Audience to Listen

Probably, you are thinking that you have been eating unhealthy food and nothing has happened to you. Yet, you may not have experienced some of the risks of poor diet, I am here to illustrate to you why you should always have healthy nutrition to boost your health and avoid common diseases that you could develop in the span of your life.

Credibility Statement

While I am not a qualified doctor or nutritionist, I have conducted ample and elaborate research on the strategies for healthy eating.

Today, I will explore three strategies of healthy eating, their benefits, and consequences if not properly followed.

I will first talk about vegetables and fruits
Then, I will talk about proteins and carbohydrates
Finally, I will discuss saturated fats and sugar

Now that I have given you an overview of my topic today, let’s explore my first major point.

It is recommended that we consume vegetables and fruits regularly to stay healthy.

Consumption of vegetables is integral to the health of our bodies:

The Dietary Guidelines for Americans states that people should eat more vegetables to boost their health and prevent themselves from chronic diseases (DietaryGuidelines.gov., 2020).
Surprisingly, only 9% of the people consumed the recommended portions of vegetables in their diet (CDC, 2021b).
In their book, Vegetables: Importance of Quality Vegetables to Human Health , Asaduzzaman and Asao (2018) illustrate that failure to consume the recommended amounts of vegetables in daily meals is associated with increased risk of cancer and stroke.
Moreover, Asaduzzaman and Asao (2018) expound that lack of proper intake of vegetables causes vitamin deficiency diseases such as scurvy (lack of vitamin C) and Sclerosis (lack of vitamin A).

Consumption of fruits is highly encouraged as one of the major eating habits that all people should embrace.

In its 2019 publication, World Health Organization (WHO) explains that fruit intake is associated with disease prevention as it enhances the immunity of our bodies.
Furthermore, WHO (2019) highlights that fruits reduce the risk of adiposity in adolescents and young children.
As its publication shows, failure to take appropriate amounts of fruits leads to increased risk for various diseases such as myocardial infarction.
WHO emphasizes that lack of adequate fruit servings in the meals could cause different types of cancer.
While fruits are crucial in our nutritious feeding, only 12% of Americans eat the recommended amount of fruits (CDC, 2021b).

TRANSITION: Now that we have talked about vegetables and fruits, let us delve into proteins and carbohydrates.

Proteins and carbohydrates are essential for our bodies

While some people could be vegetarians, the need for proteins in dietary consumption is crucial.

The Dietary Guidelines for Americans, 2020-2025 indicate that proteins could be obtained from animals such as poultry, meat, seafood, and dairy or plant sources for vegetarians (DietayGuidelines.gov., 2020).
Nutrition scholars, Shan et al. (2019) state that proteins are essential to repair body cells besides promoting growth and development in pregnant women, children, and teenagers.
Failure to consume the recommended amounts of protein causes various diseases.
As Shan et al. (2019) explain, insufficient protein in the body leads to impaired mental health, muscle-tissue shrinkage, weak immune system, marasmus, and ultimately, total organ failure.

Carbohydrates

In their article, nutritionists, Shan et al. (2019) note that carbohydrates are needed in the body as a source of the energy we use to perform daily activities.
Therefore, it is important to consume the required portions of carbohydrates for our muscles, brain, and other body parts to function normally.
According to Shan et al. (2019), failure to meet the recommended carbohydrate intake leads to low blood sugar causing hypoglycemia.
Furthermore, Shan et al. (2019) present that carbohydrates deficiency results in ketosis, characterized by bad breath, mental fatigue, joint pains, headache, and nausea.

TRANSITION: Let us now talk about the last major point in my speech, saturated fats, and sugars

It is imperative to avoid saturated fats and sugars

The Dietary Guidelines for Americans, 2020-2025 recommend that people should limit the consumption of saturated fats to live healthy lives.

The food we consume must stay within one’s calorie needs for our bodies to operate normally.
People are not supposed to eat excess calories beyond the levels recommended in the Dietary Guidelines.
The Dietary Guidelines call upon Americans to consume foods with the least amounts of saturated fats (less than 10% of the total calories consumed per day, DietaryGuidelines.gov, 2020).
CDC (2021a) reports that excessive saturated fats cause higher levels of blood cholesterol eventually leading to heart diseases or stroke.

Besides, the Dietary Guidelines recommend that Americans’ choice of beverages and single food should be nutrient-dense but, with no added processed sugars.

A healthy dietary habit limits the amount of processed sugars to fewer than 10% of the total calories consumed daily (DietaryGuidelines.gov, 2020).
CDC (2021a) posits that consumption of sugar is the root cause of type 2 diabetes, well as increased risk of heart disease and obesity among Americans.

TRANSITION TO CLOSE: As I conclude my speech today, I would like to remind you that the principal capital asset in our lives in good health.

Re-State Central Idea

Incorporating healthy eating in our diets is critical but, lack of it increases the risk of developing the various disease.

Today we have talked about strategies of healthy eating, their benefits, and consequences if not properly followed.

First, we talked about vegetables and fruits
Then, we explored proteins and carbohydrates
Finally, we discussed about saturated fats and sugar

Tie Back to Audience

I hope as you leave this place today, you have appropriate information that would encourage you to observe healthy eating habits.

Closure Statement

While most people have the necessary information we need about dietary consumption; nutrition-related diseases are on the rise. From today, everyone must take full responsibility for their eating habits.

Permissions Icon Permissions

A systematic review was conducted to examine the barriers to, and facilitators of, healthy eating among young people (11–16 years). The review focused on the wider determinants of health, examining community- and society-level interventions. Seven outcome evaluations and eight studies of young people's views were included. The effectiveness of the interventions was mixed, with improvements in knowledge and increases in healthy eating but differences according to gender. Barriers to healthy eating included poor school meal provision and ease of access to, relative cheapness of and personal taste preferences for fast food. Facilitators included support from family, wider availability of healthy foods, desire to look after one's appearance and will-power. Friends and teachers were generally not a common source of information. Some of the barriers and facilitators identified by young people had been addressed by soundly evaluated effective interventions, but significant gaps were identified where no evaluated interventions appear to have been published (e.g. better labelling of food products), or where there were no methodologically sound evaluations. Rigorous evaluation is required particularly to assess the effectiveness of increasing the availability of affordable healthy food in the public and private spaces occupied by young people.

Healthy eating contributes to an overall sense of well-being, and is a cornerstone in the prevention of a number of conditions, including heart disease, diabetes, high blood pressure, stroke, cancer, dental caries and asthma. For children and young people, healthy eating is particularly important for healthy growth and cognitive development. Eating behaviours adopted during this period are likely to be maintained into adulthood, underscoring the importance of encouraging healthy eating as early as possible [ 1 ]. Guidelines recommend consumption of at least five portions of fruit and vegetables a day, reduced intakes of saturated fat and salt and increased consumption of complex carbohydrates [ 2, 3 ]. Yet average consumption of fruit and vegetables in the UK is only about three portions a day [ 4 ]. A survey of young people aged 11–16 years found that nearly one in five did not eat breakfast before going to school [ 5 ]. Recent figures also show alarming numbers of obese and overweight children and young people [ 6 ]. Discussion about how to tackle the ‘epidemic’ of obesity is currently high on the health policy agenda [ 7 ], and effective health promotion remains a key strategy [ 8–10 ].

Evidence for the effectiveness of interventions is therefore needed to support policy and practice. The aim of this paper is to report a systematic review of the literature on young people and healthy eating. The objectives were

(i) to undertake a ‘systematic mapping’ of research on the barriers to, and facilitators of, healthy eating among young people, especially those from socially excluded groups (e.g. low-income, ethnic minority—in accordance with government health policy);

(ii) to prioritize a subset of studies to systematically review ‘in-depth’;

(iii) to ‘synthesize’ what is known from these studies about the barriers to, and facilitators of, healthy eating with young people, and how these can be addressed and

(iv) to identify gaps in existing research evidence.

General approach

This study followed standard procedures for a systematic review [ 11, 12 ]. It also sought to develop a novel approach in three key areas.

First, it adopted a conceptual framework of ‘barriers’ to and ‘facilitators’ of health. Research findings about the barriers to, and facilitators of, healthy eating among young people can help in the development of potentially effective intervention strategies. Interventions can aim to modify or remove barriers and use or build upon existing facilitators. This framework has been successfully applied in other related systematic reviews in the area of healthy eating in children [ 13 ], physical activity with children [ 14 ] and young people [ 15 ] and mental health with young people [16; S. Oliver, A. Harden, R. Rees, J. Shepherd, G. Brunton and A. Oakley, manuscript in preparation].

Second, the review was carried out in two stages: a systematic search for, and mapping of, literature on healthy eating with young people, followed by an in-depth systematic review of the quality and findings of a subset of these studies. The rationale for a two-stage review to ensure the review was as relevant as possible to users. By mapping a broad area of evidence, the key characteristics of the extant literature can be identified and discussed with review users, with the aim of prioritizing the most relevant research areas for systematic in-depth analysis [ 17, 18 ].

Third, the review utilized a ‘mixed methods’ triangulatory approach. Data from effectiveness studies (‘outcome evaluations’, primarily quantitative data) were combined with data from studies which described young people's views of factors influencing their healthy eating in negative or positive ways (‘views’ studies, primarily qualitative). We also sought data on young people's perceptions of interventions when these had been collected alongside outcomes data in outcome evaluations. However, the main source of young people's views was surveys or interview-based studies that were conducted independently of intervention evaluation (‘non-intervention’ research). The purpose was to enable us to ascertain not just whether interventions are effective, but whether they address issues important to young people, using their views as a marker of appropriateness. Few systematic reviews have attempted to synthesize evidence from both intervention and non-intervention research: most have been restricted to outcome evaluations. This study therefore represents one of the few attempts that have been made to date to integrate different study designs into systematic reviews of effectiveness [ 19–22 ].

Literature searching

A highly sensitive search strategy was developed to locate potentially relevant studies. A wide range of terms for healthy eating (e.g. nutrition, food preferences, feeding behaviour, diets and health food) were combined with health promotion terms or general or specific terms for determinants of health or ill-health (e.g. health promotion, behaviour modification, at-risk-populations, sociocultural factors and poverty) and with terms for young people (e.g. adolescent, teenager, young adult and youth). A number of electronic bibliographic databases were searched, including Medline, EMBASE, The Cochrane Library, PsycINFO, ERIC, Social Science Citation Index, CINAHL, BiblioMap and HealthPromis. The searches covered the full range of publication years available in each database up to 2001 (when the review was completed).

Full reports of potentially relevant studies identified from the literature search were obtained and classified (e.g. in terms of specific topic area, context, characteristics of young people, research design and methodological attributes).

Inclusion screening

Inclusion criteria were developed and applied to each study. The first round of screening was to identify studies to populate the map. To be included, a study had to (i) focus on healthy eating; (ii) include young people aged 11–16 years; (iii) be about the promotion of healthy eating, and/or the barriers to, or facilitators of, healthy eating; (iv) be a relevant study type: (a) an outcome evaluation or (b) a non-intervention study (e.g. cohort or case control studies, or interview studies) conducted in the UK only (to maximize relevance to UK policy and practice) and (v) be published in the English language.

The results of the map, which are reported in greater detail elsewhere [ 23 ], were used to prioritize a subset of policy relevant studies for the in-depth systematic review.

A second round of inclusion screening was performed. As before, all studies had to have healthy eating as their main focus and include young people aged 11–16 years. In addition, outcome evaluations had toFor a non-intervention study to be included it had to

(i) use a comparison or control group; report pre- and post-intervention data and, if a non-randomized trial, equivalent on sociodemographic characteristics and pre-intervention outcome variables (demonstrating their ‘potential soundness’ in advance of further quality assessment);

(ii) report an intervention that aims to make a change at the community or society level and

(iii) measure behavioural and/or physical health status outcomes.

(i) examine young people's attitudes, opinions, beliefs, feelings, understanding or experiences about healthy eating (rather than solely examine health status, behaviour or factual knowledge);

(ii) access views about one or more of the following: young people's definitions of and/or ideas about healthy eating, factors influencing their own or other young people's healthy eating and whether and how young people think healthy eating can be promoted and

(iii) privilege young people's views—presenting views directly as data that are valuable and interesting in themselves, rather than only as a route to generating variables to be tested in a predictive or causal model.

Non-intervention studies published before 1990 were excluded in order to maximize the relevance of the review findings to current policy issues.

Data extraction and quality assessment

All studies meeting inclusion criteria underwent data extraction and quality assessment, using a standardized framework [ 24 ]. Data for each study were entered independently by two researchers into a specialized computer database [ 25 ] (the full and final data extraction and quality assessment judgement for each study in the in-depth systematic review can be viewed on the Internet by visiting http://eppi.ioe.ac.uk ).

Outcome evaluations were considered methodologically ‘sound’ if they reported:Only studies meeting these criteria were used to draw conclusions about effectiveness. The results of the studies which did not meet these quality criteria were judged unclear.

(i) a control or comparison group equivalent to the intervention group on sociodemographic characteristics and pre-intervention outcome variables.

(ii) pre-intervention data for all individuals or groups recruited into the evaluation;

(iii) post-intervention data for all individuals or groups recruited into the evaluation and

(iv) on all outcomes, as described in the aims of the intervention.

Non-intervention studies were assessed according to a total of seven criteria (common to sets of criteria proposed by four research groups for qualitative research [ 26–29 ]):

(i) an explicit account of theoretical framework and/or the inclusion of a literature review which outlined a rationale for the intervention;

(ii) clearly stated aims and objectives;

(iii) a clear description of context which includes detail on factors important for interpreting the results;

(iv) a clear description of the sample;

(v) a clear description of methodology, including systematic data collection methods;

(vi) analysis of the data by more than one researcher and

(vii) the inclusion of sufficient original data to mediate between data and interpretation.

Data synthesis

Three types of analyses were performed: (i) narrative synthesis of outcome evaluations, (ii) narrative synthesis of non-intervention studies and (iii) synthesis of intervention and non-intervention studies together.

For the last of these a matrix was constructed which laid out the barriers and facilitators identified by young people alongside descriptions of the interventions included in the in-depth systematic review of outcome evaluations. The matrix was stratified by four analytical themes to characterize the levels at which the barriers and facilitators appeared to be operating: the school, family and friends, the self and practical and material resources. This methodology is described further elsewhere [ 20, 22, 30 ].

From the matrix it is possible to see:

(i) where barriers have been modified and/or facilitators built upon by soundly evaluated interventions, and ‘promising’ interventions which need further, more rigorous, evaluation (matches) and

(ii) where barriers have not been modified and facilitators not built upon by any evaluated intervention, necessitating the development and rigorous evaluation of new interventions (gaps).

Figure 1 outlines the number of studies included at various stages of the review. Of the total of 7048 reports identified, 135 reports (describing 116 studies) met the first round of screening and were included in the descriptive map. The results of the map are reported in detail in a separate publication—see Shepherd et al. [ 23 ] (the report can be downloaded free of charge via http://eppi.ioe.ac.uk ). A subset of 22 outcome evaluations and 8 studies of young people's views met the criteria for the in-depth systematic review.

The review process.

Outcome evaluations

Of the 22 outcome evaluations, most were conducted in the United States ( n = 16) [ 31–45 ], two in Finland [ 46, 47 ], and one each in the UK [ 48 ], Norway [ 49 ], Denmark [ 50 ] and Australia [ 51 ]. In addition to the main focus on promoting healthy eating, they also addressed other related issues including cardiovascular disease in general, tobacco use, accidents, obesity, alcohol and illicit drug use. Most were based in primary or secondary school settings and were delivered by teachers. Interventions varied considerably in content. While many involved some form of information provision, over half ( n = 13) involved attempts to make structural changes to young people's physical environments; half ( n = 11) trained parents in or about nutrition, seven developed health-screening resources, five provided feedback to young people on biological measures and their behavioural risk status and three aimed to provide social support systems for young people or others in the community. Social learning theory was the most common theoretical framework used to develop these interventions. Only a minority of studies included young people who could be considered socially excluded ( n = 6), primarily young people from ethnic minorities (e.g. African Americans and Hispanics).

Following detailed data extraction and critical appraisal, only seven of the 22 outcome evaluations were judged to be methodologically sound. For the remainder of this section we only report the results of these seven. Four of the seven were from the United States, with one each from the UK, Norway and Finland. The studies varied in the comprehensiveness of their reporting of the characteristics of the young people (e.g. sociodemographic/economic status). Most were White, living in middle class urban areas. All attended secondary schools. Table I details the interventions in these sound studies. Generally, they were multicomponent interventions in which classroom activities were complemented with school-wide initiatives and activities in the home. All but one of the seven sound evaluations included and an integral evaluation of the intervention processes. Some studies report results according to demographic characteristics such as age and gender.

Soundly evaluated outcome evaluations: study characteristics (n = 7)

RCT = Randomized Controlled Trial; CT = controlled trial (no randomization); PE = process evaluation.

Separate evaluations of the same intervention in two populations in New York (the Bronx and Westchester County).

The UK-based intervention was an award scheme (the ‘Wessex Healthy Schools Award’) that sought to make health-promoting changes in school ethos, organizational functioning and curriculum [ 48 ]. Changes made in schools included the introduction of health education curricula, as well as the setting of targets in key health promotion areas (including healthy eating). Knowledge levels, which were high at baseline, changed little over the course of the intervention. Intervention schools performed better in terms of healthy food choices (on audit scores). The impact on measures of healthy eating such as choosing healthy snacks varied according to age and sex. The intervention only appeared possibly to be effective for young women in Year 11 (aged 15–16 years) on these measures (statistical significance not reported).

The ‘Know Your Body’ intervention, a cardiovascular risk reduction programme, was evaluated in two separate studies in two demographically different areas of New York (the Bronx and Westchester County) [ 45 ]. Lasting for 5 years it comprised teacher-led classroom education, parental involvement activities and risk factor examination in elementary and junior high schools. In the Bronx evaluation, statistically significant increases in knowledge were reported, but favourable changes in cholesterol levels and dietary fat were not significant. In the Westchester County evaluation, we judged the effects to be unclear due to shortcomings in methods reported.

A second US-based study, the 3-year ‘Gimme 5’ programme [ 40 ], focused on increasing consumption of fruits and vegetables through a school-wide media campaign, complemented by classroom activities, parental involvement and changes to nutritional content of school meals. The intervention was effective at increasing knowledge (particularly among young women). Effects were measured in terms of changes in knowledge scores between baseline and two follow-up periods. Differences between the intervention and comparison group were significant at both follow-ups. There was a significant increase in consumption of fruit and vegetables in the intervention group, although this was not sustained.

In the third US study, the ‘Slice of Life’ intervention, peer leaders taught 10 sessions covering the benefits of fitness, healthy diets and issues concerning weight control [ 41 ]. School functioning was also addressed by student recommendations to school administrators. For young women, there were statistically significant differences between intervention and comparison groups on healthy eating scores, salt consumption scores, making healthy food choices, knowledge of healthy food, reading food labels for salt and fat content and awareness of healthy eating. However, among young men differences were only significant for salt and knowledge scores. The process evaluation suggested that having peers deliver training was acceptable to students and the peer-trainers themselves.

A Norwegian study evaluated a similar intervention to the ‘Slice of Life’ programme, employing peer educators to lead classroom activities and small group discussions on nutrition [ 49 ]. Students also analysed the availability of healthy food in their social and home environment and used a computer program to analyse the nutritional status of foods. There were significant intervention effects for reported healthy eating behaviour (but not maintained by young men) and for knowledge (not young women).

The second ‘North Karelia Youth Study’ in Finland featured classroom educational activities, a community media campaign, health-screening activities, changes to school meals and a health education initiative in the parents' workplace [ 47 ]. It was judged to be effective for healthy eating behaviour, reducing systolic blood pressure and modifying fat content of school meals, but less so for reducing cholesterol levels and diastolic blood pressure.

The evidence from the well-designed evaluations of the effectiveness of healthy eating initiatives is therefore mixed. Interventions tend to be more effective among young women than young men.

Young people's views

Table II describes the key characteristics of the eight studies of young people's views. The most consistently reported characteristics of the young people were age, gender and social class. Socioeconomic status was mixed, and in the two studies reporting ethnicity, the young people participating were predominantly White. Most studies collected data in mainstream schools and may therefore not be applicable to young people who infrequently or never attend school.

Characteristics of young people's views studies (n = 8)

All eight studies asked young people about their perceptions of, or attitudes towards, healthy eating, while none explicitly asked them what prevents them from eating healthily. Only two studies asked them what they think helps them to eat healthy foods, and only one asked for their ideas about what could or should be done to promote nutrition.

Young people tended to talk about food in terms of what they liked and disliked, rather than what was healthy/unhealthy. Healthy foods were predominantly associated with parents/adults and the home, while ‘fast food’ was associated with pleasure, friendship and social environments. Links were also made between food and appearance, with fast food perceived as having negative consequences on weight and facial appearance (and therefore a rationale for eating healthier foods). Attitudes towards healthy eating were generally positive, and the importance of a healthy diet was acknowledged. However, personal preferences for fast foods on grounds of taste tended to dominate food choice. Young people particularly valued the ability to choose what they eat.

Despite not being explicitly asked about barriers, young people discussed factors inhibiting their ability to eat healthily. These included poor availability of healthy meals at school, healthy foods sometimes being expensive and wide availability of, and personal preferences for, fast foods. Things that young people thought should be done to facilitate healthy eating included reducing the price of healthy snacks and better availability of healthy foods at school, at take-aways and in vending machines. Will-power and encouragement from the family were commonly mentioned support mechanisms for healthy eating, while teachers and peers were the least commonly cited sources of information on nutrition. Ideas for promoting healthy eating included the provision of information on nutritional content of school meals (mentioned by young women particularly) and better food labelling in general.

Table III shows the synthesis matrix which juxtaposes barriers and facilitators alongside results of outcome evaluations. There were some matches but also significant gaps between, on the one hand, what young people say are barriers to healthy eating, what helps them and what could or should be done and, on the other, soundly evaluated interventions that address these issues.

Synthesis matrix

Key to young people's views studies: Y1 , Dennison and Shepherd [ 56 ]; Y2 , Harris [ 57 ]; Y3 , McDougall [ 58 ]; Y4 , Miles and Eid [ 59 ]; Y5 , Roberts et al. [ 60 ]; Y6 , Ross [ 61 ]; Y7 , Watt and Sheiham [ 62 ]; Y8 , Watt and Sheiham [ 63 ]. Key to intervention studies: OE1 , Baranowski et al. [ 31 ]; OE2 , Bush et al. [ 32 ]; OE3 , Coates et al. [ 33 ]; OE4 , Ellison et al. [ 34 ]; OE5 , Flores [ 36 ]; OE6 , Fitzgibbon et al. [ 35 ]; OE7 , Hopper et al. [ 64 ]; OE8 , Holund [ 50 ]; OE9 , Kelder et al. [ 38 ]; OE10 , Klepp and Wilhelmsen [ 49 ]; OE11 , Moon et al. [ 48 ]; OE12 , Nader et al. [ 39 ]; OE13 , Nicklas et al. [ 40 ]; OE14 , Perry et al. [ 41 ]; OE15 , Petchers et al. [ 42 ]; OE16 , Schinke et al. [ 43 ]; OE17 , Wagner et al. [ 44 ]; OE18 , Vandongen et al. [ 51 ]; OE19 , Vartiainen et al. [ 46 ]; OE20 , Vartiainen et al. [ 47 ]; OE21 , Walter I [ 45 ]; OE22 , Walter II [ 45 ]. OE10, OE11, OE13, OE14, OE20, OE21 and OE22 denote a sound outcome evaluation. OE21 and OE22 are separate evaluations of the same intervention. Due to methodological limitations, we have judged the effects of OE22 to be unclear. Y1 and Y2 do not appear in the synthesis matrix as they did not explicitly report barriers or facilitators, and it was not possible for us to infer potential barriers or facilitators. However, these two studies did report what young people understood by healthy eating, their perceptions, and their views and opinions on the importance of eating a healthy diet. OE2, OE12, OE16 and OE17 do not appear in the synthesis matrix as they did not address any of the barriers or facilitators.

In terms of the school environment, most of the barriers identified by young people appear to have been addressed. At least two sound outcome evaluations demonstrated the effectiveness of increasing the availability of healthy foods in the school canteen [ 40, 47 ]. Furthermore, despite the low status of teachers and peers as sources of nutritional information, several soundly evaluated studies showed that they can be employed effectively to deliver nutrition interventions.

Young people associated parents and the home environment with healthy eating, and half of the sound outcome evaluations involved parents in the education of young people about nutrition. However, problems were sometimes experienced in securing parental attendance at intervention activities (e.g. seminar evenings). Why friends were not a common source of information about good nutrition is not clear. However, if peer pressure to eat unhealthy foods is a likely explanation, then it has been addressed by the peer-led interventions in three sound outcome evaluations (generally effectively) [ 41, 47, 49 ] and two outcome evaluations which did not meet the quality criteria (effectiveness unclear) [ 33, 50 ].

The fact that young people choose fast foods on grounds of taste has generally not been addressed by interventions, apart from one soundly evaluated effective intervention which included taste testings of fruit and vegetables [ 40 ]. Young people's concern over their appearance (which could be interpreted as both a barrier and a facilitator) has only been addressed in one of the sound outcome evaluations (which revealed an effective intervention) [ 41 ]. Will-power to eat healthy foods has only been examined in one outcome evaluation in the in-depth systematic review (judged to be sound and effective) (Walter I—Bronx evaluation) [ 45 ]. The need for information on nutrition was addressed by the majority of interventions in the in-depth systematic review. However, no studies were found which evaluated attempts to increase the nutritional content of school meals.

Barriers and facilitators relating to young people's practical and material resources were generally not addressed by interventions, soundly evaluated or otherwise. No studies were found which examined the effectiveness of interventions to lower the price of healthy foods. However, one soundly evaluated intervention was partially effective in increasing the availability of healthy snacks in community youth groups (Walter I—Bronx evaluation) [ 45 ]. At best, interventions have attempted to raise young people's awareness of environmental constraints on eating healthily, or encouraged them to lobby for increased availability of nutritious foods (in the case of the latter without reporting whether any changes have been effected as a result).

This review has systematically identified some of the barriers to, and facilitators of, healthy eating with young people, and illustrated to what extent they have been addressed by soundly evaluated effective interventions.

The evidence for effectiveness is mixed. Increases in knowledge of nutrition (measured in all but one study) were not consistent across studies, and changes in clinical risk factors (measured in two studies) varied, with one study detecting reductions in cholesterol and another detecting no change. Increases in reported healthy eating behaviour were observed, but mostly among young women revealing a distinct gender pattern in the findings. This was the case in four of the seven outcome evaluations (in which analysis was stratified by gender). The authors of one of the studies suggest that emphasis of the intervention on healthy weight management was more likely to appeal to young women. It was proposed that interventions directed at young men should stress the benefits of nutrition on strength, physical endurance and physical activity, particularly to appeal to those who exercise and play sports. Furthermore, age was a significant factor in determining effectiveness in one study [ 48 ]. Impact was greatest on young people in the 15- to 16-year age range (particularly for young women) in comparison with those aged 12–13 years, suggesting that dietary influences may vary with age. Tailoring the intervention to take account of age and gender is therefore crucial to ensure that interventions are as relevant and meaningful as possible.

Other systematic reviews of interventions to promote healthy eating (which included some of the studies with young people fitting the age range of this review) also show mixed results [ 52–55 ]. The findings of these reviews, while not being directly comparable in terms of conceptual framework, methods and age group, seem to offer some support for the findings of this review. The main message is that while there is some evidence to suggest effectiveness, the evidence base is limited. We have identified no comparable systematic reviews in this area.

Unlike other reviews, however, this study adopted a wider perspective through inclusion of studies of young people's views as well as effectiveness studies. A number of barriers to healthy eating were identified, including poor availability of healthy foods at school and in young people's social spaces, teachers and friends not always being a source of information/support for healthy eating, personal preferences for fast foods and healthy foods generally being expensive. Facilitating factors included information about nutritional content of foods/better labelling, parents and family members being supportive; healthy eating to improve or maintain one's personal appearance, will-power and better availability/lower pricing of healthy snacks.

Juxtaposing barriers and facilitators alongside effectiveness studies allowed us to examine the extent to which the needs of young people had been adequately addressed by evaluated interventions. To some extent they had. Most of the barriers and facilitators that related to the school and relationships with family and friends appear to have been taken into account by soundly evaluated interventions, although, as mentioned, their effectiveness varied. Many of the gaps tended to be in relation to young people as individuals (although our prioritization of interventions at the level of the community and society may have resulted in the exclusion of some of these interventions) and the wider determinants of health (‘practical and material resources’). Despite a wide search, we found few evaluations of strategies to improve nutritional labelling on foods particularly in schools or to increase the availability of affordable healthy foods particularly in settings where young people socialize. A number of initiatives are currently in place which may fill these gaps, but their effectiveness does not appear to have been reported yet. It is therefore crucial for any such schemes to be thoroughly evaluated and disseminated, at which point an updated systematic review would be timely.

This review is also constrained by the fact that its conclusions can only be supported by a relatively small proportion of the extant literature. Only seven of the 22 outcome evaluations identified were considered to be methodologically sound. As illustrated in Table III , a number of the remaining 15 interventions appear to modify barriers/build on facilitators but their results can only be judged unclear until more rigorous evaluation of these ‘promising’ interventions has been reported.

Finally, it is important to acknowledge that the majority of the outcome evaluations were conducted in the United States, and by virtue of the inclusion criteria, all the young people's views studies were UK based. The literature therefore might not be generalizable to other countries, where sociocultural values and socioeconomic circumstances may be quite different. Further evidence synthesis is needed on barriers to, and facilitators of, healthy eating and nutrition worldwide, particularly in developing countries.

The aim of this study was to survey what is known about the barriers to, and facilitators of, healthy eating among young people with a view to drawing out the implications for policy and practice. The review has mapped and quality screened the extant research in this area, and brought together the findings from evaluations of interventions aiming to promote healthy eating and studies which have elicited young people's views.

There has been much research activity in this area, yet it is disappointing that so few evaluation studies were methodologically strong enough to enable us to draw conclusions about effectiveness. There is some evidence to suggest that multicomponent school-based interventions can be effective, although effects tended to vary according to age and gender. Tailoring intervention messages accordingly is a promising approach which should therefore be evaluated. A key theme was the value young people place on choice and autonomy in relation to food. Increasing the provision and range of healthy, affordable snacks and meals in schools and social spaces will enable them to exercise their choice of healthier, tasty options.

We have identified that several barriers to, and facilitators of, healthy eating in young people have received little attention in evaluation research. Further work is needed to develop and evaluate interventions which modify or remove these barriers, and build on these facilitators. Further qualitative studies are also needed so that we can continue to listen to the views of young people. This is crucial if we are to develop and test meaningful, appropriate and effective health promotion strategies.

We would like to thank Chris Bonell and Dina Kiwan for undertaking data extraction. We would also like to acknowledge the invaluable help of Amanda Nicholas, James Thomas, Elaine Hogan, Sue Bowdler and Salma Master for support and helpful advice.

Healthy Food Essay

500+ words essay on healthy food.

Before starting your daily activity, you must have food. Food is essential for our body besides water. Eating healthy food gives you the required nutrients you need to maintain a healthy lifestyle. Your daily food should have carbohydrates, proteins, water, vitamins, fat and minerals. To keep ourselves fit, we need healthy food.

When we talk about our health, healthy food plays a crucial role. It helps preserve our health, and some nutrients renew the health of various organs. Besides, healthy food is always delicious and mouthwatering. Kids, nowadays, should eat healthy food more than ever. We must encourage kids to eat healthy food so that our future generations become healthy and fit.

We should speak more often about the harmful effects of unhealthy food and the positive impact of healthy food. In this way, we can teach our kids about eating healthy foods from an early age.

To keep our internal organs healthy, we should make a habit of eating healthy food. Unhealthy food welcomes life-threatening diseases like heart attack, high or low blood pressure, increased or decreased glucose level, etc. In today’s scenario, with so many changes around the world in terms of climate, pollution, etc., eating healthy food should be on our priority list.

Advantages of Eating Healthy Food

We get a solid and fit body by eating healthy and nutritious food.
Healthy food also gives the body physical strength; that way, one can go about their duties comfortably.
Eating healthy food gives good health, saving you from wasting time, money and resources seeking medical assistance and solutions.
By eating nutritious food, we can protect our bodies from getting serious diseases like diabetes, hypertension, elevated cholesterol, and so forth.
It also helps maintain our weight, and unhealthy food leads to obesity.
Likewise, healthy sustenance gives us a fit and fine body and smooth skin.
We never feel lazy in the wake of eating light and solid nourishment; instead, we feel dynamic and energetic.
Eating healthy food helps build the body and its immunity levels, enhancing the living standards one gets to enjoy.
It is one of the ways individuals enjoy life as they get to spend good time with friends and family.
Healthy food is, therefore, a principal requirement for the body.

Junk Food vs Healthy Food

In today’s scenario, consumption of junk food is increasing rapidly, due to which the fast-food market is also growing fast. Junk foods are easier to prepare and delicious. It became more accessible after the arrival of the food delivery apps. People can now sit at their homes and order junk food as per their choice.

But, unknowingly, we are compromising our health by having junk food. After eating it, you will feel more satisfied. Junk food leads to poor concentration and creates digestive problems as it contains less fibre, which causes indigestion.

Junk food also results in varying blood sugar levels because it contains less protein and carbohydrates. Consumption of junk food also increases levels of triglyceride and cholesterol.

When we talk about healthy food, it contains a plethora of nutrients. It keeps our bodies physically and mentally fit. It enhances our immune system and develops our brain functionality. If we are worried about our health, we should not consume processed food.

We know that junk food seems to be more appealing and tempting, but it comes at a very high price. Therefore, we should eat healthy food to live a longer and healthier life.

Conclusion of Healthy Food Essay

We can end the essay by stating that eating healthy food is our primary need. Eating healthy food is a simple way to increase the ease of the body and the happiness of the mind. Eating junk food will make our bodies weaker and have low immunity. So, it is essential to consume healthy food to maintain good health.

Healthy Eating Habits

Introduction, nutrition and healthy eating, healthy living strategies, works cited.

Proper nutrition and physical activity are important aspects of healthy livings as their contribution to reducing the rates of chronic diseases is a well-established fact. On the other hand, unhealthy eating habits and lack of physical exercise lead to diseases such as diabetes, obesity, stroke, heart diseases, and osteoporosis, which can sometimes be fatal.

The findings of a study conducted in 1990 established that 14% of all deaths in the U.S. could be attributed to poor eating habits and physical inactivity with sedentary lifestyles, a contributor to 23% of disease-related deaths[1]. Healthy eating habits involve the inclusion of fruits, vegetables, and important minerals in the diet and the reduction of saturated fat intake.

Regular physical activity is essential for healthy living as it reduces the chances of developing coronary heart disease. The reduced physical activity and the changes in eating and dieting habits have long-lasting health consequences on the general health of the public, particularly the children and adolescents.

Developing good eating habits for children and adolescents is important for their long-term nutritional well-being. Proper nutrition, together with regular physical activity, enhances proper physical growth, promotes positive self-esteem, and promotes the children’s capacity to learn. In addition, good nutrition and physical activity also prevent diseases such as obesity.

According to the Center for Disease Control and Prevention, there has been a rapid increase in the rate of children becoming overweight over the past twenty years, attributed to poor nutrition and exercise habits[2]. Proper nutrition and physical exercise habits are important in maintaining a healthy living, and this can be started at an early age.

The parents eating habits influence the children’s feeding practices, and therefore, teaching children healthy eating habits in schools would make them practice healthy behaviors throughout their lives[3]. Increased consumption of vegetables and fruits with a reduction in fat intake coupled with physical activity are among the healthy habits to curb the overweight problems in children.

The consequences of physical inactivity and poor dietary habits in children and adults alike are obesity, which is defined as having a body mass index (BMI) of more than 30k/m2.

The prevalence of obesity increased among the population between 1991 and 2000, affecting all the segments of the population in the U.S[4]. Obesity is the major cause of health complications, including diabetes (type II), hypertension, heart diseases, stroke, osteoarthritis, respiratory complications, and some cancers.

The socio-economic consequences of obesity, now an epidemic, are overwhelming. The intervention strategies usually focus on promoting good eating habits, including a reduction in calorie intake and helping people increase their physical activity. In children, breastfeeding prevents excessive weight gain and obesity in early childhood and adolescence and, thus, a good strategy of reducing childhood obesity[5].

For adults and young people, poor dietary habits and lack of physical activity increase the risk of developing health-related complications. These segments of the population have an increased risk for chronic diseases such as high blood pressure and elevated cholesterol levels.

By establishing healthier eating habits combined with physical activity, the onset of these diseases would be prevented[6]. Additionally, active lifestyles and healthy eating behaviors help people with chronic diseases to cope with or control the effects of the diseases and prevent deterioration of their physical condition.

In order to promote healthy living and prevent complications arising from poor eating habits such as obesity, various healthy living strategies involving behavior change are important[7]. To reduce health-related complications in the elderly, regular physical exercises and sporting, including jogging and regular visits to the gym, can be very helpful.

Given the immense benefits of physical exercises, social support is one way of motivating people to remain physically fit and live healthy lifestyles. This can be achieved by providing programs that help people incorporate exercises into their daily routines.

Furthermore, increasing community-based programs and facilities would encourage people to exercise and in the process, live healthy lifestyles. Increased consumption of vegetables and fruits with lower calorie intake lowers the incidences of diseases, including cardiovascular diseases and some cancers[8].

Excessive intake of saturated fats is the major cause of cardiovascular diseases and cancers[9]. Therefore, to achieve healthy living, the diet should constitute plenty of fruits and vegetables and less saturated fat. Daily consumption of at least two servings of fruit and three servings of vegetables is recommended for healthy living; however, less than 25% of the U.S. population consumes this[10].

For young children and adolescents, school-based physical education (PE) enables students to engage in physical activities to promote their physical well-being and learning. Prolonged television watching among children and adolescents increases overweight incidences among children[11].

This may be because television watching leads to a decline in calorie-burning physical activity and reduces the children’s metabolic rate. Furthermore, television watching may influence the children’s eating habits contributing to an increased risk of obesity.

Physical inactivity and poor eating habits cause health-related complications such as obesity and heart diseases. The intervention methods usually focus on promoting physical exercises and healthier eating habits. Given the current increase in health-related diseases, it is evident that reduced physical activity and unhealthy eating habits have adverse impacts on the general health of the public, more especially the young people.

Essay on Eating Healthy Food (869 Words)

March 1, 2018 by Study Mentor Leave a Comment

We all have heard the common phrase which says “ Health is wealth ”. This teaches us that our health is the wealth we have.

It does not matter whether we are rich or poor, if we have a good health we have the wealth. Health is more important than wealth.

This does not mean we cannot have any wealth with us. It means that we should focus more on our health than the wealth.

We will have a lot of wealth someday but that will go the other day. If we have a good health today and we maintain our health, it will not go away from us like the wealth. It will stay with us.

If we don’t have wealth we can still survive by working. But if we lose our health, the available wealth will also be of no use to us. So, we should always remain healthy.

In order to lead a healthy life, we should eat healthy. If we eat food which is healthy for us, we will always have a good and healthy life. It is necessary to eat the right food in our diet.

It is important to eat healthy food to have a proper life free from sickness. But in today’s world, everything has advanced so much that we get food items readymade.

People these days consume more of these readymade foods which are most of the time unhealthy and junk foods.

Yes, they are delicious and tempting to eat but they are the cause of deterioration of our health. Due to busy schedule people don’t have the time to make healthy food.

This is the reason why people choose to eat the readymade food. But people should know that it is important for one to eat healthy and nutritious food. One should know which food is healthy and which is not.

Table of Contents

Why should we eat healthy?

But the type of food people eats these days, those type of food don’t give us the essential nutrients that is needed for the daily functioning of our body.

We should eat the right food for these essential nutrients. Eating healthy is very important for us. It will help us to be productive in our work.

We can do all our work with the energy that we get from eating healthy food.

Just like when a vehicle does not have the right amount of fuel, it does not work properly. It moves and then again stops. It seems like the driver is continuously applying the brakes.

In the similar manner, when we don’t have enough food in our body, we will not be able to function properly in our daily life.

If we don’t have the essential nutrients in our body, our condition will become like the vehicle without enough fuel.

If we eat the right food and get the essential nutrients, we will be happy because our brain gets affected by the food we consume.

When we don’t eat food properly, we tend to become stressed and be in anger. So, the right food and right nutrients will help us to be happy and not get stressed.

Eating healthy food will help in the proper development of our body. The fast foods and junk foods will be replaced if we eat healthy foods.

So, there is no chance of gaining extra weight or losing weight. This is because the healthy foods help us to control our weight. Healthy food is always good in quality.

So, we don’t have to buy them in large quantity and we can save our money. But if we consume more of fast foods we tend to spend a lot of money. Yes, even it tastes better but the quality is not better than the healthy food.

So, we tend to buy more of these food. Everyone is conscious about their body. If we eat healthy, it will have a positive impact on our body on its own.

We don’t have to waste our money for buying products to make our body better. If we don’t eat healthy food, we will be suffering from various sickness or diseases.

We will remain healthy if we eat healthy food. We will be free from diseases by eating healthy. We will be fit and fine.

As we will be free from any sort of disease, we will live longer. We will not be getting sick, so there will not be any extra expenditure for the health treatment.

What are the eating healthy habits?

People consume more of ready made food or fast foods instead of home food.

But are these really healthy habits? No, they are not. People cut short on their food thinking if they eat less, they will be fit and will not gain weight.

But that is more harmful. Eating less will not give the body the necessary nutrients it need for the daily functioning.

Instead, the person has to face other serious problems. We need to follow various eating healthy habits which will ultimately benefit us for our own betterment.

The most important is a person should drink water regularly. We should not drink water only when we are thirsty.

Water helps in proper digestion of food, eliminates waste and maintains our body temperature. We should prefer eating such food which will give us more nutrients.

Instead of eating readymade food, we should cook healthy food at home. Whatever food we cook, we must wash before we start cooking them.

And most important cleanliness should be maintained everywhere which will directly affect our way of eating healthy.

We should not be encouraged by the advertisements of food that is shown by different companies for the sale of their food items.

Most of these advertisements will only tempt us to eat them. We don’t know whether these food items are healthy for us or not.

We should know what type of food is healthy for us. Some of the healthy foods are whole grain food items, milk, fish, rice, fruits, eggs etc.

We should eat the items which give are rich in carbohydrates, proteins, vitamins, fats and minerals. These will help in the overall processing of our body.

We should never skip any of the meals. We should eat all the meals on time and in the right quantity.

Like the breakfast should be eaten like king because if the breakfast is proper we will be energetic to work the entire day.

Dinner should be eaten less because after that we don’t have to any work which requires energy.

If we see delicious food at some place, we should not eat them in such a manner like we eating after a long time. This will spoil our health.

What are the consequences of not eating healthy?

We should always eat healthy. We should not be encouraged from the advertisements shown to us. We should know what we are eating.

Eating unhealthy food will directly affect our health. Eating healthy food will help us to be free from diseases.

If we consume junk foods and ignore healthy food we will be prone to many serious diseases. We will become sick physically and mentally both.

Our health will start deteriorating and body will become weak. Eating unhealthy will not cause problems only for a shorter period of time but it will last for longer.

If we change our eating habits then there is a chance that our health will improve. We will not be able to do any work if we don’t eat healthy food, our life will be totally disturbed.

We will not be happy. We will always be angry and stressed. We will not be able to concentrate anywhere.

In order to lead a long and healthy life, it is important for us to eat healthy and follow good eating habits.

Eating healthy will help not only to our body but in other areas as well. As our brain is directly affected by the food we eat, our behaviour changes if we don’t eat healthy food.

If we want to live longer, we should eat healthy. We cannot lose our life because of our decision to eat foods which are not good for us.

Healthy Food Essay

Essay on Healthy Food

Food is essential for our body for a number of reasons. It gives us the energy needed for working, playing and doing day-to-day activities. It helps us to grow, makes our bones and muscles stronger, repairs damaged body cells and boosts our immunity against external harmful elements like pathogens. Besides, food also gives us a kind of satisfaction that is integral to our mental wellbeing, but there are some foods that are not healthy. Only those food items that contain nutrients in a balanced proportion are generally considered as healthy. People of all ages must be aware of the benefits of eating healthy food because it ensures a reasonably disease-free, fit life for many years.

Switching to a healthy diet doesn't have to be a one-size-fits-all approach. You don't have to be perfect, you don't have to eliminate all of your favourite foods and you don't have to make any drastic changes all at once—doing so frequently leads to straying or abandoning your new eating plan.

Making a few tiny modifications at a time is a recommended approach. Maintaining modest goals will help you achieve more in the long run without feeling deprived or overwhelmed by a very drastic diet change. Consider a healthy diet as a series of tiny, accessible actions such as including a salad in your diet once a day. You can slowly add additional healthy options as your minor modifications become habitual.

Cultivating a positive relationship with food is also crucial. Rather than focusing on what you should avoid, consider what you may include on your plate that will benefit your health such as nuts for heart-healthy, predominant fat that reduces low-density lipoprotein levels called monounsaturated fatty acids(raspberries) for fibre and especially the substances that inhibit oxidation which we call antioxidants.

Why is Healthy Food Important?

Living a healthy lifestyle has immense payback. Over time, making smart eating choices lowers your risk of cardiovascular disease, certain malignancies, type 2 diabetes, obesity, and even anxiety and depression. Daily, you will have more energy, feel better and possibly even be in a better mood.

It all boils down to how long and how good your life is. According to several surveys, A healthy diet consists of whole grains, vegetables, fruits, nuts, and fish. A higher diet of red or processed meats on the other hand doubled the chance of dying young.

Types of Healthy Food:

Following are the various types of healthy foods and their respective nutritional value:

Cereals,potatoes,bread and other root vegetables- These are the main sources of carbohydrates. The calories obtained from them enable us to do work.

Pulses, milk and milk products, eggs, bird meat, animal meat in limited quantities - these are great sources of protein. They build muscles and repair the damaged cells of our body, i.e., they are important for our immunity.

Ghee, butter, nuts and dry fruits, edible oil used in restrained quantities- These are rich sources of good fat. They provide more energy to our body than carbohydrates but should be consumed in a smaller amount.

Fresh fruits, vegetables and leafy vegetables, fish, egg, milk-these are good sources of vitamins, minerals and antioxidants are essential for normal functioning of the body. Though they are needed in small amounts, nowadays, nutrition experts prescribe their higher consumption as they help to fight lifestyle diseases like diabetes, obesity and even cancer.

Different types of healthy food when included in our daily diet in the right proportions along with water and roughage comprise a balanced diet. However, a balanced diet is not the same for all individuals considering many factors. It depends on a person’s age, gender, condition of the body-healthy or suffering from any disease and the type of work or physical activity a human does.

Benefits of Eating Healthy

Healthy food intake nourishes both our physical and mental health and helps us stay active for many years. One who break downs this broad benefit into micro-benefits will see that eating healthy:

Helps us in weight management

Makes us agile and increases our productivity

Decreases the risk of heart diseases, stroke, diabetes mellitus, poor bone density, and some cancers, etc.

Helps in uplifting mood

Improves memory

Improves digestion and appetite

Improves sleep cycle

Healthy food habits are inculcated in children by their parents early on. These habits along with the right education and physical exercise lead to an overall development of an individual which ultimately becomes the greatest resource of a country.

What is Unhealthy Food or Junk Food?

To fully understand the prominence of healthy food in our diet, we must also be aware of unhealthy food, that is, the food that we must avoid eating. These are mainly junk food items which are low in nutritional value and contain an excessive amount of salt, sugar and fats which is not healthy for a human body.

Junk food is one of the unhealthy intakes in the present day scenario. It makes us more unfit than ever before. It is high time that one realised this and adopted a healthy food habit for a sustainable lifestyle.

Steps to improve Eating Habits:

Make a detailed plan; break down the timings; kind of food to be included in each meal and keep the plan weekly and avoid making the process dull and repetitive.

Cook your food, minimise eating from outside. It helps keep the ingredients, quality and measurements in check as well as saves money.

Stock your kitchen with healthy snacks for your cravings rather than processed food so that your options are reduced to consuming unhealthy food.

Take the process slowly. You do not have to have a strict plan; ease yourself into a healthy mindset. Your mind and body will adjust gradually. Consistency is important.

Track your eating habits to understand the intake of food, items, portions etc. This motivates you to see the progress over time and make changes according to your needs.

Myths About Healthy Food:

Carrots affect eyesight: According to historic times, during World War II, there was a popular belief that eating a lot of veggies would assist maintain the pilot's eyes in good repair. In actuality, the fighter pilot's eyesight was aided by advanced technology. However, the myth has persisted since then and many parents still use this narrative to get their children to eat more veggies. Carrots are high in vitamin A and make a terrific supplement to any healthy diet, but they don't usually help you see better.

Fat-Free Food : Health foods continue to dominate grocery store shelves but it's always a good idea to look beyond the label before buying. This is especially true when it comes to "fat-free," "low-fat," and "non-fat" foods. It's generally true that anything with less fat is preferable for some dairy and meat items.

Lower fat alternatives in packaged and processed foods contain other dangerous additives as fat substitutes. Manufacturers compensate for the loss of fat in packaged cookies, for example, by adding other undesirable elements like sugar.

Protein shakes: Pre-made smoothie beverages and protein powder mixes which typically claim to contain less sugar than milkshakes, slushies and diet sodas are likely to be the popular choice among customers because of the above mentioned reason. They both have the same amount of sugar and artificial sweeteners.

However, this is not true of all pre-made protein shakes and smoothies. Many of them, particularly the plant-based mixtures, are still nutritious additions to a balanced diet. Check the nutrition label to be sure there are no added sugars or artificially sweetened mixtures.

Organic food is better: Foods that are grown organically are better for you. Nutritionists labelling a product as organic doesn't mean it's superior to non-organic foods. It's a popular misperception that organic produce is nutritionally superior to non-organic produce. Organic produce has the same caloric and nutritional value as non-organic produce since it is grown and prepared according to federal rules.

FAQs on Healthy Food Essay

1) Is sugar unhealthy?

Sugar is considered to be harmful for a healthy diet. Since it tastes so good in many foods, humans tend to increase it’s intake. It is also hidden in foods you wouldn't expect. It makes body organs fat, depresses well-being and also leads to heart diseases. However, to maintain a healthy diet, it is necessary to distinguish between natural and added sugars. Sugars are carbs that provide an essential source of energy and nourishment, nevertheless, sugar is often added to many popular dishes, which is when sugar becomes unhealthy. Natural sugars found in fruits and vegetables are regarded as healthy when consumed in moderation. Still added sugars give little nutritional benefit and contribute considerably to weight gain, compromising your healthy diet. As a result, it's critical to double-check the label.

2) What is Omega 3?

Omega-3 is the superfood of the fat group, which is particularly useful for various conditions, since the term "superfood" was coined. Omega-3 fatty acid is a medicine used in treating nutritional deficiencies. It is one of the essential nutrients with good antioxidant properties. Depression, memory loss, heart problems, joint and skin disorders and general improvement of physical and mental health and wellness are among them. Omega-3 which is abundant in fish-based diets is considered a necessary fatty acid for good health.

Food is essential for survival as it provides us with energy to carry out daily activities like walking, running, working, and socializing. Healthy eating and a healthy diet promote a healthy lifestyle. On the contrary, unhealthy food that includes junk food results in many diseases.

Essay On Importance Of Eating Healthy Food – 700 Word Long Essay

Food is a basic necessity of life as it helps us to survive. Food provides us the energy to carry out our daily tasks that include working, walking, and socializing. The food we eat represents our personality, culture, and traditions. A healthy diet leads to healthy habits and regularly eating unhealthy foods leads to many diseases that negatively impact your physical and mental wellbeing. In this essay, I will discuss the benefits of healthy food and how it impacts our daily lives.

Eating vegetables and fruits in large quantities helps to reduce the risk of developing chronic diseases such as diabetes and reduces the risk of a heart attack. Vegetables provide many healthy nutrients that are needed to maintain good health. However, eating just vegetables and no meant content is not a very good practice. Being a vegetarian is good for health but there are some nutrients that you can only get from meat and not plants. Research has shown that some essential nutrients like vitamin B12 and vitamin D13 along with many other nutrients are only present in meat and other animal-sourced foods. Therefore, everyone should look to adopt a balanced diet that contains a little bit of everything in an adequate amount.

Obesity is one of the most common health problems being faced by the modern generation. Junk food is one of the key causes of obesity because junk food contains high-calorie, high fat, high sugar, and high salt content. Health experts identify high fats, sugar, and raw salt as key contributors that cause heart diseases, kidney failure, and other health problems.

Healthy foods have many health-related benefits. Healthy foods can improve a person’s mood and enhance their mental status. When a person’s body is under stress, protein is often broken down into amino acids which aid the body to deal with stress. Protein-rich diets such as dairy products can help to enhance the protein level in the body. Moreover, diets rich in omega-3 fats such as nuts, as well as vitamin-rich and mineral-rich diets including fruits and vegetables help maintain stable blood sugar levels. Healthy foods such as beetroot, apricots, and radishes also improve the overall body appearance. Sugary items have been linked to dry skin and early aging. These are the reasons why one should always eat healthy food.

Unhealthy foods have many disadvantages as they are the main reason for many diseases. Consuming processed food, junk food, and all types of fast foods can have very bad effects on the body. These problems lead to weight gain, excess body fat, increase the risk of heart disease, cause high blood pressure, and even early death in some cases. Artificial sweeteners

High calories have been shown to increase blood pressure and increase the chances of an early death occurring. However, vegetables, fruits, exercise, and overall calorie reduction enable the body to work efficiently. Junk food does not have vital micronutrients such as minerals and vitamins. Consequently, the consumer misses the vital nutrients needed to boost the body’s well being hence his risk of early death is enhanced.

In conclusion, everyone should make a healthier choice by eating healthy foods and developing healthy eating habits. The human body can be kept perfectly healthy by eating healthy food and maintaining a healthy diet. Always make a wiser choice because your body deserves better!

Eating Healthy Food Leads To A Healthy Life Essay In 200 WordsShort Essay

https://www.pexels.com/photo/colorful-bottles-with-smoothies-beside-carrots-ginger-leaves-and-berries-4443492/

Food is one of three basic necessities in life, the other two being air and water. Food is essential to survival. Our food choices reflect many things about our life and personality. In today’s world, we mostly see only two kinds: the ones who live to eat and those who eat to live. Both of them are food extremists and people should move towards a balanced diet that comprises everything in adequate amounts. Healthy foods lead to a healthy body and a healthy weight. On the contrary unhealthy foods destroy our digestive system and damage the whole body. In this essay on healthy food, I will discuss how and why healthy food leads to a healthy lifestyle.

Eating healthy food and pursuing a healthy diet is an essential way to add important nutrients to your food intake. Nutritionists encourage eating more vegetables to make digestion easier. They also suggest that we should avoid eating more calories than what is required by not eating meat every day. A person who only relies on junk food, fast food, and processed food becomes obese in no time. Obese people cannot live a healthy life because they are unable to do more physical activities. Lying on the bed all day and eating junk only leads to more troubles like diabetes, high blood pressure, and problems with the digestive system.

Some common healthy food easily includes whole grains, dairy products, green vegetables, eggs, and lean meat. However, always making a healthy food choice is not easy. Nowadays the world is becoming fast, busy, and demanding; there is a limited time to do everything. The same goes with food as most people don’t have enough time to prepare healthy food so they opt for fast food instead. Processed foods, energy drinks, deep-fried snacks, and sodas are also among the most unhealthy foods.

In conclusion, healthier choices enhance our health by making our lives healthy and happy. On the contrary, unhealthy food choices lead to chronic diseases, malnutrition, high cholesterol, and obesity. Given the high rate of deaths in the U.S. caused by factors related to poor diet, lack of physical exercise, and high consumption of junk foods, people need to consider consuming healthy food.

A nutritionist shares her simple diet for optimal health—'I'm not trying to be the most creative person on Earth'

The impact of what you eat daily on your overall health cannot be overstated, and we can all look to the diets of experts like nutritionists for guidance.

Carissa Galloway has 10 years of experience as a registered dietitian nutritionist and is a nutrition consultant and personal trainer for Premier Protein.

Prior to her career as a nutritionist, Galloway was a sideline sports reporter. A realization about her own eating habits and their effects on her health led her to an interest in nutrition, which not only changed her day job but also how she approached her diet.

"I found that as I was traveling, I wasn't eating healthy. I wasn't feeling energetic, I was sluggish," Galloway tells CNBC Make It.

Here's the diet that Galloway follows now for better health.

How this nutritionist eats for optimal health

When it comes to Galloway's diet, she aims to get three types of foods in every meal:

Protein is "hugely important for muscle growth and repair," Galloway says.

"For weight management, protein foods help you feel full and satisfied," she adds. "So when you have a protein in every meal and snack, you're helping support steady blood glucose levels, and you're watching out for that blood sugar roller coaster."

The kinds of protein that Galloway reaches for are:

Protein shakes
Seafood high in omega-3's

"If you're using meat in your meals, you want the amount of protein to be about the size of your palm," she says.

"I want a fruit or a vegetable anytime that I eat anything. And I want to make sure that I vary my colors," she says.

"Because when you're varying your different colors, that means you're varying your different antioxidants and vitamins that are in them."

Her family's favorite fruits to start their mornings with are berries, and she's a huge fan of dark leafy greens like spinach, kale and arugula.

"But also the broccoli, the cauliflower. There's research that shows they have anti-cancer fighting properties, " Galloway adds.

3. Fiber-rich foods

Adults ages 50 and under are recommended by the U.S. Department of Agriculture to get 25 and 38 grams of fiber a day, for women and men respectively.

Yet, on average, U.S. adults are only getting around 10 to 15 grams of total fiber daily, according to Harvard Health Publishing .

This is why Galloway aims to eat fiber-rich foods in every meal. Some foods that have high fiber content include leafy greens, avocados, raw almonds, apples and seeds like chia seeds.

A nutritionist's typical breakfast, lunch and dinner

This is what Galloway made for breakfast, lunch and dinner for her and her kids on the day that she spoke with CNBC Make It.

Breakfast: Overnight oats, made with plant-based milk, cinnamon and protein powder, topped with nuts and berries
Mid-morning snack: Premier Protein high-protein shakes

Healthy Eating tips

I've given several presentations lately on "food as medicine" — meaning, eating for health. We all know the statistics. More than 74% of adults in the U.S. are obese or overweight. Another 1.6% are underweight. Both can negatively affect your health.

People who are underweight have a higher risk of malnutrition, decreased immune function and anemia. Those who are overweight have an increased risk for high blood pressure, heart disease, diabetes and sleep disorders.

This spring — as you tackle spring cleaning — do a spring assessment on what you're eating. Are you cooking at home? Do you include a vegetable and fruit at each meal? Are you eating from all the food groups — whole grains, fruits, vegetables, lean meat and low-fat dairy — to get all the nutrients you need? It's a great season to make a commitment to healthier eating to feel better, look better and be healthier.

Here are some tips to help you get started.

No. 1: Eat whole foods. Rather than fixing something from a box, plan your meals with lean protein, fruits, vegetables and whole grains. That's where the nutrients are. And those nutrients, vitamins and minerals will provide energy throughout the day and help you maintain a healthy weight. Choose less of the processed foods like deli or sausage meat, cookies, crackers and box mixes (which can be high in sodium).

No. 2: Start slow. Take your favorite lasagna recipe and swap half the pasta for zucchini ribbons, or add finely chopped carrots to your spaghetti sauce. Mix half mashed cauliflower with mashed potatoes. Try a whole-grain version of your favorite pasta. Try replacing potato chips at lunch with crunchy baby carrot sticks.

No. 3: One of the best changes you can make for healthier eating is to cut back on your salt and sugar. The Dietary Guidelines recommend no more than 2,300 milligrams of sodium per day, about the amount in 1 teaspoon of salt. But it's the salt shaker that adds up the sodium for most people. It's also in hidden sources like chips, pickles, bacon, sausage, deli meats and condiments such as soy sauce. As for added sugars, the recommendation is less than 10% of total calories.

No. 4: Add healthy fats. Saturated fats such as butter can increase cholesterol. Instead, choose monounsaturated fats such as olive, peanut or canola oil. Saute your chicken or fish in olive oil instead of butter. Omega-3 fats, found in avocados, nuts, salmon, tuna, sardines, flax seed and chia, are heart-healthy.

No. 5: Switch to whole grains. Choose brown rice over white, or try quinoa. Add barley to a soup. Start your day with oatmeal.

These are all great starts to a healthier you, and the end result will be a healthy weight for you.

Q: Can changing your diet really slow brain aging?

A: Research shows it can — by as much as 7 1/2 years. The foods that make a difference include broccoli, fatty fish, avocados, beans, eggs, dark chocolate, walnuts, berries and coffee. In fact, more fruits and vegetables of all types are helpful. The Cleveland Clinic recommends adding apples, tomatoes and onions to your diet, along with barley, brown rice, chia, flaxseed, tea and turmeric. Think whole foods, foods rich in fiber, antioxidants and omega-3s. Choose less added sugars, saturated fat and foods with refined flour. If you're still not sure, stick with a healthy eating pattern based on the U.S. Department of Agriculture's MyPlate.

I typically have basil growing in my garden. When I find a recipe that uses it, I like to give it a try. Here's a recipe for Ginger-Basil Chicken and Broccoli Stir-Fry that includes not only fresh basil but also plenty of fresh vegetables. It's from Eating Well magazine.

GINGER-BASIL CHICKEN AND BROCCOLI STIR-FRY

Servings: 4 (1 1/3 cups each)

5 tablespoons low sodium soy sauce, divided

4 tablespoons rice vinegar, divided

4 teaspoons cornstarch, divided

1 pound chicken cutlets, thinly sliced

4 teaspoons honey

2 tablespoons canola oil, divided

6 cloves garlic, minced

4 teaspoons grated fresh ginger

2 scallions, sliced

4 cups broccoli florets

2 tablespoons water

2 cups snow peas

1/2 cup packed fresh basil leaves, coarsely chopped or torn

Combine 2 tablespoons soy sauce, 1 tablespoons vinegar and 2 teaspoons cornstarch in a shallow dish. Stir in chicken, and set aside. Mix the remaining 3 tablespoons soy sauce, 3 tablespoons vinegar, 2 teaspoons cornstarch and honey in small bowl, and set near the stove. Heat 1 tablespoon oil in a large flat-bottom wok or cast-iron skillet over high heat until shimmering. Add the chicken in a single layer, and cook until golden on one side, 1 to 2 minutes. Flip and cook for 1 minute more. Transfer chicken to a plate. Add the remaining 1 tablespoon oil to the pan. Add garlic, ginger and scallions, and cook, stirring for 30 seconds. Stir in broccoli and water. Quickly cover, and steam for 2 minutes. Add snow peas, and return the chicken and any accumulated juices. Stir the reserved sauce, and add to the pan. Cook, stirring frequently and scraping up any browned bits, until the sauce is thickened, 2 to 3 minutes. Remove from heat, and stir in basil.

Per serving: 300 calories; 31 grams protein; 19 grams carbohydrates; 10 grams fat; 83 milligrams cholesterol; 4 grams fiber; 9 grams total sugars (6 grams added); 686 milligrams sodium.
