Mindful Eating: A Path to a Healthy Body Class 6 Case-Based Questions

Question 1.
We all know that each eatable dish is usually made up of one or more ingredients, which we get from plants or animals. These ingredients contain some components that are must for our body. These components are termed as nutrients. The major nutrients in our food are proteins, carbohydrates, vitamins, fats and minerals. In addition to them, food contains dietary fibres and water too which are eQuestion ually needed by our body. There are many types of carbohydrates. The main carbohydrates found in our food are starch and sugars.
With the help of some simple methods we can test whether cooked food or a raw ingredient contains one or more of these nutrients. For conducting these tests, we will need solutions of iodine, copper sulphate and caustic soda. We can try these tests on cooked food items as well as raw materials.
I. Name the two carbohydrates mainly present in our food.
II. Write the names of three reagents reQuestion uired to test the presence of nutrients in food.
III. What are nutrients? Give one example.
IV. Name all the components present in our food.
Answer:
I. Starch and Sugars.
II. (a) Caustic soda solution
(b) Copper sulphate solution
(c) Iodine solution
III. 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.
IV. The major nutrients in our food are carbohydrates, fats, proteins, vitamins and minerals. Food also contains dietary fibres and water.

Question 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 Question quantity v 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 Question uantity of a food item for testing. If the food you want to test is a solid, you first need to make a paste or powder of it. Grind or mash a small Question uantity 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 2 drops of solution of copper sulphate and 10 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 colour indicates presence of proteins in the food item.

For fats, take a small Question uantity 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 observe it carefully. If you see an oily patch on paper, then it shows that the food item contains fat. Absence of oily patch shows that the food item does not contain any 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. .
I. Which colour indicates the presence of proteins in the food items?
II. What we use to test the presence of starch?
III. How can we test the presence of fats in food items?
IV. Solutions of copper sulphate and caustic soda are used to test the presence of which nutrient?
Answer:
I. Violet.
II. We put drops of dilute Iodine solution to test the presence of starch.
III. Wrap the food item in a piece of paper and crush it. Next, straighten the paper and observe it carefully. If you see an oily patch on paper, then it shows that the food item contains fat.
IV. Both are used to detect the presence of proteins in food items.

Question 3.
Foods containing fats and carbohydrates are also called ‘energy-giving foods’. Proteins are needed for the growth and repair of our body. Foods rich in proteins are often called ‘body-building foods’. Vitamins help in protecting our body against diseases. Vitamins are of different kinds. Our body needs all types of vitamins in small Quantities. Vitamin A keeps our skin and eyes healthy. Vitamin C helps our body to fight against 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” 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, pulses, potatoes, fresh fruits and vegetables are main sources of roughage.
