CBSE Case Study Questions Class 6 Science Components of Food

Case study 1.

We know that each dish is usually made up of one or more ingredients, which we get from plants or animals. These ingredients contain some components that are needed by our body. These components are called nutrients. The major nutrients in our food are named carbohydrates, proteins, fats, vitamins and minerals. In addition, food contains dietary fibres and water which are also needed by our body.

With some simple methods we can test whether cooked food or a raw ingredient contains one or more of these nutrients. For carrying out these tests, you will need solutions of iodine, copper Sulphate and caustic soda. You will also need a few test tubes and a dropper. Try these tests on cooked food items as well as raw materials. If the required solutions are not available in readymade form, you can prepare them as given in the Table 1. There are many types of carbohydrates. The main carbohydrates found in our food are in the form of starch and sugars.

Que. 1) Starch and sugar are the forms of carbohydrates mainly present in our food?

Que. 2) To make the solution of caustic soda, we need to dissolve ………………………………………………………………………….…….. in 100ml of ……………………………………………………………….….. ?

(a) Iodine and water

(b) Salt and water

(c) Caustic soda and salt

(d) Caustic soda and water

Que. 3) Which of the following is NOT required to test the presence of nutrients in food?

(a) Vinegar solution

(b) Iodine solution

(c) Copper Sulphate

(d) Caustic soda solution

Que. 4) What are nutrients? Give one example?

Que. 5) Name all the components present in our food?

Que. 1) a)True

Que. 2) d) Caustic soda and water

Que. 3) a) Vinegar solution

Que. 4) Answer: Our food is made up of one or more ingredients. These ingredients contain components that are needed by our body. These components are called Nutrients. For example- Proteins

Que. 5) Answer: The major nutrients in our food are carbohydrates, proteins, fats, vitamins and minerals. Apart from nutrients, food also contains dietary fibres and water.

Case study 2

The tests for presence of carbohydrates, proteins and fats are simpler to do as compared to the tests for other nutrients. Let us begin by testing different food items to see if they contain carbohydrates. Take a small quantity of a food item or a raw ingredient. Put 2-3 drops of dilute Iodine solution on it. Observe if there is any change in the colour of the food item. A blue-black colour indicates that it contains starch.To test the presence of proteins in food we need to take a small quantity of a food item for testing. If the food you want to test is a solid, you first need to make a paste of it or powder it. Grind or mash a small quantity of the food item. Put some of this in a clean test tube, add 10 drops of water to it and shake the test tube. Now, using a dropper, add two drops of solution of copper sulphate and ten drops of solution of caustic soda to the test tube. Shake well and let the test tube stand for a few minutes. You will see that the contents of the test tube will turn violet. A violet colourindicates presence of proteins in thefood item.

For fats, take a small quantity of a food item.Wrap it in a piece of paper and crush it.Take care that the paper does not tear.Now, straighten the paper and observeit carefully. If you see an oily patch on paper,then it shows that the food item contains fat. The food items may sometimes contain a little water. Therefore, after you have rubbed an item on paper, let the paper dry for a while. If there were any water that may have come from food, it would dry up after some time. If no oily patch shows up after this, the food item does not contain any fat.

Que.1)Which colour indicates the presence of proteins in the food items?

d) Blue – black

Que.2) We put drops of dilute Iodine solution to test the presence of …………………………………………………………………………………………. ?

Que.3)If the colour of the food item turns blue- black, then it contains fat.

Que.4) How can we test the presence of fats in food items?

Que.5) Solutions of Copper sulphate and caustic soda are used to test the presence of which nutrient? Elaborate how its presence is detected?

Que.1. a)Violet

Que.2. b) Starch

Que.3. b) False

Que.4) Answer: The presence of fats in food items can be test by taking a small quantity of a food item. Wrapping it in a piece of paper and crushing it. Next, straightening the paper and observing it carefully. If you see an oily patch on paper, then it shows that the food item contains fat.

Que.5) Answer: Solutions of both the copper sulphate and caustic soda are used to test the presence of proteins in food items.

When the colour of the food item turns violet, it indicates the presence of proteins in the food item.

Case study 3

Foods containing fats and carbohydrates are also called ‘energy giving foods’. Proteins are needed for the growthand repair of our body. Foods proteins are often called ‘body building foods’. Vitamins help in protecting our body against diseases. Vitamins are of different kinds known by different names. Our body needs all types of vitamins in small quantities. Vitamin A keeps ourskin and eyes healthy. Vitamin C helpsbody to fight against many diseases.Vitamin D helps our body to use calcium for bones and teeth.

However, in a given raw material, one particular nutrient may be present in much larger quantity than in others. For example, rice has more carbohydrates than other nutrients. Thus, we say that rice is a “carbohydrate Rich” source of food.

Besides these nutrients, our body needs dietary fibres and water. Dietary fibres are also known as Roughage. Roughage is mainly provided by plant products in our foods. Whole grains and pulses, potatoes, fresh fruits and vegetables are main sources of roughage.

Que.1) …………………………..…………………..…………………… keeps our skin and eyes healthy?

a) Vitamin D

Que.1. a) Vitamin A

Que.2. b) False

Que.3. d) Proteins

Que.4) Answer: Dietary fibres are also known as Roughages. It is mainly provided by plant products in our foods. The main sources of roughages are whole grains and pulses, potatoes, fresh fruits and vegetables.

Que.5) Answer: Vitamins help in protecting our body against diseases. Vitamins are of different kinds known by different names. Our body needs all types of vitamins in small quantities. Vitamin A keeps our skin and eyes healthy. Vitamin C helps body to fight against many diseases. Vitamin D helps our body to use calcium for bones and teeth.

Case study 4

The food we normally eat in a day is our diet. For growth and maintenance of good health, our diet should have all the nutrients that our body needs, in right quantities. Not too much of one and not too little of the other. The diet should also contain a good amount of roughage and water. Such a diet is called a balanced diet.Pulses, groundnut, soyabean,Sprouted seeds (moong and BengalGram), fermented foods (South IndianFoods such as idlis), a combination ofFlours (missi roti, thepla made fromCereals and pulses), banana, spinach,Sattu, jaggery, available vegetables and other such foods provide many Nutrients.

Eating the right kind of food is not enough. It should also be cooked properly so that its nutrients are notlost. But there are some nutrients that get lost in the process of cooking and preparations. If the vegetables and fruits are washed after cutting or peeling them, it may result in the loss of some vitamins.

The skins of many vegetables and fruits contain vitamins and minerals. Similarly, repeated washing of rice and pulses may remove some vitamins and minerals present in them. We all know that cooking improves the taste of food and makes it easier to digest. At the same time, cooking also results in the loss of certain nutrients. Many useful proteins and considerable amounts of minerals are lost if excess water is used during cooking and is then thrown away. Vitamin C gets easily destroyed by heat during cooking.Also It can be very harmful for us to eat too much of fat rich foods and we may end up suffering from a condition called obesity.

Que.1) An example of fermented fooditem is ……………………………………………………………………………………. .

d) Sprouted seeds

Que.2) A considerable amount of …………………………………………………………………………..………….…….. And ……………………………………………………………….…..  are lost if we use water in excessive amount during cooking?

Que.4) What do you understand by the term “balanced diet?”

Que.5) Mention the disadvantages of cooking food?

Que.1. b)Idli

Que.2. c) Minerals and proteins

Que.3. a)True

Que.4) Answer: Our food should have all the necessary nutrients in right quantities, along with a good amount of roughage and water. Such a diet is known as a balanced diet.

Que.5) Answer: Cooking results in the loss of certain nutrients. Many useful proteins and considerable amounts of minerals are lost if excess water is used during cooking and is then thrown away. Vitamin C gets easily destroyed by heat during cooking.

Case Study 5

Our meals usually have at least one item made of some kind of grain. Other items could be a dal or a dish of meat and vegetables. It may also include items like curd, butter milk and pickles. Some examples of meals from different regions are given in table 1. Select food items you depicted on the map in Chapter 1. Add some more meals to this list and enter these in Table 1. Sometimes, we may not really have all this variety in our meals. If we are travelling, we may eat whatever is available on the way. It may not be possible for some of us, to eat such a variety of items, most of the time. There must be some reason though, why meals usually consist of such a distribution. Do you think that our body needs different kinds of food for some special purpose?

Q 1.) Name the grain most commonly eaten by the people of Punjab?

a) Makki roti

→ There are six main components present in food:

Carbohydrates, fats, proteins, vitamins, minerals and fibers.

→ These components fulfill the different needs of the body.

→ Carbohydrates are the compound which is made up of three elements:-

Carbon, Hydrogen and Oxygen

→ Carbohydrate provides energy to our body, which keeps it going throughout the day.

→ The main carbohydrates found in our food are in the form of sugars and starch. If food contains starch we can easily test it.

→ The sources of carbohydrates include cereals such as wheat, maize, rice, jawar, bajra, potatoes, bread etc.

→ We can test the presence of carbohydrates by iodine test.

Test for carbohydrates:

Step 1 : Take the food item in the test tube and add 2-3 drops of dilute iodine solution to it.

Step 2 : After some time if the colour changes to blue-black, it indicates the presence of starch in the food item.

→ Proteins are the complex compounds made up of carbon, hydrogen, oxygen, nitrogen and sulphur.

→ The sources of proteins are: cheese, egg, soya bean, pulses, meat etc.

→ Protein is known as body-building food.

Test for proteins:

Step 1 : Take food item in the test tube and Add 10 drops of water to it and mix well.

Step 2 : Now add 2 drops of copper sulphate and ten drops of caustic soda (sodium hydroxide) solution.

Step 3 : Mix it well and keep it undisturbed for some time.

Step 3 : After some time you observe the development of violet color in the test tube, it indicates the presence or the proteins.

→ Fat also provides energy to our body. Fat gives more energy as compared to carbohydrates.

→ Some sources of fat are oil, ghee, egg yolk, milk, butter etc.

Test for fats:

Step 1 : Take some food item in a paper and wrap it.

Step 2 : Then try to crush it taking care that the paper is not torn.

Step 3 : After that take out the food item and allow the paper to be dried for some time.

Step 4 : If you can find the oil spots on the paper it indicates the presence of fats in the food item.

→ Vitamins are a group of organic compound which is essential in small amounts for maintaining normal health and development.

→ Vitamins help in protecting our body against diseases. It helps in keeping our eyes, bones, teeth and gums healthy.

→ There are two types of vitamins some are fat soluble and some are water soluble.

→ Vitamins are of different types: - vitamin A, vitamin C, vitamin D, vitamin E, and vitamin K.

→ There are some other vitamins known as vitamin B complex which contain vitamin B 1 , vitamin B 2 , vitamin B 3 , vitamin B 5 , vitamin B 6 , vitamin B 7 , vitamin B 9  and vitamin B 12 .

→ Minerals perform important functions such as formation of bones, teeth and blood cell and also maintain the normal heartbeat.

→ Roughage is also called dietary fibers.

→ It consist of indigestible plant carbohydrates called cellulose.

→ The source of Roughage is fresh fruits, whole grains and pulses.

→ Our diet should have all the required nutrients in right proportions this should also contain some water and dietary fibers this kind of diet is called as Balanced diet.

→ Balance diet is important for growth and maintenance of good health,

→ It can be very harmful for us to eat too much of fat rich foods and we may end up suffering from a condition called  obesity.

→ Diseases that occur due to lack of nutrients over a long period are called as deficiency diseases.

→ If we do not take a particular nutrient over a long period of time, we suffer from its deficiency.

Important Questions for CBSE Class 6 Science Chapter 2 - Free PDF Download

Class 6 Science chapter 2 contains ample information regarding food components. Good hold on this chapter will help students to fetch good marks in exams. So solving some important questions in Class 6 is going to be helpful for the students. 

When we come across a topic called Components of Food, it is divided into two categories that are either derived from plants or derived from animals. Meat, fish, and egg are all examples of food products derived from animals, and grains, pulses, etc. are derived from animals. But these are just sources from which these foods are derived. 

We know our food components consist of various elements, including carbohydrates, proteins, vitamins, minerals, etc. To have a healthy lifestyle, it is essential to have a balanced diet, including all these and not any one of them in particular. Let us look at this chapter to understand in a little more detail.

Tests for Components of Food Class 6 Important Questions 

There are many tests to understand the presence and amount of individual food components. 

Iodine Test : Iodine test is done for testing the presence of carbohydrates in any food item. Few drops of dilute iodine solution are dropped to the food sample whose carbohydrate content is tested. If the colour of the solution changes from its brown colour to a dark blue-black colour, we can infer that they contain carbohydrates. If the colour does not vary and remains the same, there would be no carbohydrate content.

Protein Test : Copper sulfate and caustic soda solutions are extensively used to test whether the protein is present or not in any food sample. The food sample to be tested is made into a paste, and the above solutions are mixed with it. It would change to a purple colour if it has protein, and in case it is absent in protein content, it may appear to be bluish.

Test for Fats: Testing a food sample for its fat content is more straightforward than another test. It does not require any chemical solutions and can be done simply with a piece of paper itself. The food to be tested is taken in a paper piece and is just crushed. If it shows oily patches in the form, we can infer that they contain fat.

We know that it is essential to have a balanced diet that includes all the vital components. But lack of certain nutrients may cause issues to our health. Diseases caused due to lack of intake of certain nutrients are called deficiency diseases. The best method to treat deficiency diseases is to have a healthy balanced diet. Let us look at some of the common deficiency diseases and their symptoms.

Deficiency in vitamin A causes night blindness. Since vitamin A is essential for the proper maintenance of skin and eyes, vitamin A deficiency results in low vision. Vitamin B1 deficiency causes a disease called Beri-Beri, whose symptoms include weight loss and weak muscles. Lack in vitamin C causes scurvy whose primary symptoms appear as bleeding gums. 

Vitamin D's weakness causes rickets, resulting in soft and tender bones with high chances of getting broken. Vitamin E deficiency causes Crohn's disease, where pale skin and rapid ageing are common symptoms. Lack of vitamin K causes haemorrhage. There would be excessive bleeding in such a condition, and clotting would be delayed.

Rather than vitamins, deficiency of minerals can also cause diseases. Lack of calcium leads to osteoporosis and osteomalacia where our bones are affected. The deficiency of iron causes anaemia, which is very common in our society. The deficiency of iodine causes goitre, which results in the enlargement of the thyroid gland. 

There are many more deficiency diseases, and we have to eat food rich in whatever components we lack to cure deficiency diseases. When diagnosed with any deficiency disease, one must consume more rich food in that particular nutrient. Deficiency diseases can be cured easily through a proper food habit itself.

Summary of CBSE Class 6 Science Chapter 2

Our body requires a balanced diet, including all the significant food components for healthy living. Carbohydrates and fats together are known as energy-giving foods. Ghee, oil, etc. make the best examples of fats, and potatoes, rice, etc. include carbohydrates in lump sum amounts stored in them in the form of starch.

The next category of components is proteins, which are the bodybuilding component of food or more accurately is the body's building blocks. They help in the growth of the body. Some of the food items rich in proteins are pulses, soya bean (a prosperous source of protein ) and meat fish, etc. from plant and animal sources.

Vitamins or minerals are considered as protective food. They help us build a robust immune system, and once we have a full immune system, we have the resistance to fight various diseases. All the fruits and green leafy vegetables are rich sources of vitamins and minerals. Vitamins are classified into two types – Fat-soluble vitamins and water-soluble vitamins. Vitamins A, D, E, K are fat-soluble vitamins, and vitamins B and C are water-soluble vitamins.

Fibre that comes as roughage is essential for the body's normal functioning although the significant part is removed as undigested food from our body.

FAQs on Important Questions for CBSE Class 6 Science Chapter 2 - Components of Food

1. Why is it Essential to Have a Balanced Diet?

A balanced diet is a diet containing all the essential components of food required for our body's proper functioning in the appropriate amount. It includes proteins, vitamins, and minerals and in short, all the necessary nutrients. As said in the definition, a balanced diet is required for our body's proper functioning. We know that deficiency of any of the nutrients necessary may cause deficiency diseases that may have serious health issues and harm our healthy lifestyle. To maintain a healthy food habit and thereby a healthy lifestyle, it is always advised to take a balanced diet.

2. What are deficiency diseases? How can they be cured?

Deficiency diseases are diseases that arise due to the absence or low amount of required nutrients in our food necessary for the proper functioning of all parts of the body. When the nutrient performing a specific function is not available sufficiently, it affects that particular function. The best method to cure deficiency diseases is to have a balanced diet as it contains all the required nutrients in the required amount. One must consult a doctor before the deficiency diseases become severe. Specific vitamin or mineral supplements can suffice the need.

3. Is it Possible for Vegetarians to Have a Balanced Diet Since They Do Not Consume Fish and Meat Products?

Fish, meat and other animal products indeed have many required nutrients. But, it is not true that vegetarians cannot have a balanced diet as they do not consume these. There are various fruits and vegetables from where all the essential nutrients can be derived. Leafy vegetables are a vast storehouse of many nutrients that non-veg products may supply. Besides, vegetarians may consume milk that is highly rich in nutrients. So it is a false belief that vegetarians cannot have a balanced diet.

5. What does it mean to have a deficiency?

When an individual eats an adequate amount of food but that food intake lacks some particular nutrient, and if this continues for a long period of time, they might be said to have a deficiency of that particular nutrient. This deficiency can be of one or of more than one nutrients. If this continues, it may result in some serious illnesses.  For instance, if a person’s protein intake is less than required, they might have stunted growth, discolouration of hair, skin diseases or other such conditions.

6. What are the main components of food according to Chapter 2 of Class 6 Science?

Every food item that we eat has in them certain components that are necessary for our body and these are called nutrients. The main nutrients include -

CARBOHYDRATES - These are present in the form of sugar and starch and perform the function of providing energy to our body.

FATS - These also provide energy to our body. Both carbohydrates and fats together are called “energy-giving foods”.

PROTEINS - Proteins are essential because they help in the growth of the body. They also play a major role when it comes to repairing various tissues and organs and are thus called “bodybuilding foods”.

VITAMINS - There are different kinds of vitamins, like vitamin A, Vitamin B, Vitamin C etc, and each has a different and specific role to perform. 

MINERALS - These are necessary for the proper growth of the body, and are required in small amounts.

7. Why should we include vitamins in our food short answer according to Chapter 2 of Class 6 Science?

Vitamins play the role of protecting the body against various diseases and help in keeping our eyes, gums, bones, teeth etc in good health. These Vitamins are of various kinds, like Vitamin A, Vitamin B, Vitamin C, Vitamin D etc. Each of these has a very specific role to play. Vitamin A helps in keeping our skin and eyes healthy. Vitamin C builds our body to fight against various diseases. Vitamin D keeps our bones strong. Thus, the intake of each one of these is essential for the healthy function of our body.

8. Besides nutrients, what are the other components that are important for our body?

Besides the nutrients, dietary fibres and water also play a very prominent role in keeping our body fit and healthy.  Dietary fibres, also known as roughage, helps our body to get rid of undigested food. These are found in plant-based foods like fruits, potatoes, pulses etc. Water, on the other hand, plays a very important role in helping to absorb the nutrients from the food. It also helps in throwing out the waste in the form of urine or sweat.

11. Tasty food is not always nutritious, and nutritious food may not always be tasty to eat. Comment with examples. Solution:

Tasty food is not always nutritious like, burgers, pizzas, chats, potato chips etc. are very tasty but not nutritious. These foods contain refined flour (Maida), spices and a lot of oil which is not good for health.

On the other hand, nutritious food may not always be tasty to eat like, boiled vegetables, pulses, leafy vegetables etc., which are not always tasty but are very good for health. These foods contain important nutrients (proteins, vitamins, minerals etc.) which help us to maintain our body strong and healthy.

12. While using iodine in the laboratory, some drops of iodine fell on Paheli’s socks, and some fell on her teacher saree. The drops of iodine on the saree turned blue-black, while their colour did not change on the socks. What can be the possible reason? Solution:

The saree of Paheli’s teacher would have contained starch. When starch is exposed to iodine solution, starch turns into blue-black, so the saree also turned blue-black. Paheli’s socks would not have contained starch and thus did not show any colour change.

13. Paheli and Boojho peeled some potatoes and cut them into small pieces. They washed and boiled them in water. They threw away the excess water and fried them in oil adding salt and spices. Although the potato dish tasted very good, its nutrient value was less. Suggest a method of cooking potatoes that will not lower the nutrients in them. Solution:

Potatoes are nutritious vegetables that provide carbohydrates, vitamins (especially vitamin C), minerals and dietary fibre. Consuming potatoes along with their skin (peel) provides extra dietary fibre and nutrients.

A method of cooking potatoes that will not lower their nutrient value is:

Wash the potatoes and cut them into thin slices. Cook the potatoes with some water along with a little amount of oil and by adding salt and spices. Cover the cooking pot while cooking. This method helps to conserve the nutrients of potatoes.

14. Paheli avoids eating vegetables but likes to eat biscuits, noodles and white bread. She frequently complains of stomach ache and constipation. What are the food items that she should include in her diet to get rid of the problem? Give a reason for your answer. Solution:

Paheli should include whole grains, whole pulses, fresh fruits and vegetables in her diet to get rid of her problems. These food items contain roughage (dietary fiber) which is lacking in Paheli’s diet.

Paheli should avoid eating biscuits, noodles and white bread as they are made up of refined flour (Maida) which does not contain any roughage or fiber. Roughage prevents constipation.

15. (a) List all those components of food that provide nutrients. (b) Mention two components of food that do not provide nutrients. Solution:

(a) Components of food that provide nutrients are carbohydrates, fats, proteins, vitamins and minerals.
