Class 6 Science chapter 1 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.

 

Deficiency Diseases

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 1

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 1 - 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 1 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 1 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.
