Answer:
Food is essential for the survival of living organisms. It provides us with energy to carry out daily activities and develop, grow and repair our body parts in case of any damage. Therefore understanding the importance of consuming the right kind of food becomes a necessity.
Furthermore, most of the food items available today are adulterated in many possible ways. The food that we consume comes from numerable sources and the variety is huge. You can think of the last meal you had, and list down sources from which your food was obtained. This helps us understand how food varies in its sources and components.
What Do Different Food Items Contain?
Each dish we eat is prepared using more than one ingredient containing different nutrients along with dietary fibres and water. Some nutrients in our food are fats, minerals, vitamins, proteins and carbohydrates.
Carbohydrates are present in the form of starch and sugars in our food. The presence of carbs in our food can be tested using a dilute iodine solution, an indication of the presence of starch is shown by black-blue colouration.
Presence of protein in food is tested using a solution of copper sulphate and caustic soda. If the solution turns violet, proteins are present.
Presence of fat in food is indicated when food wrapped in paper turns oily after releasing its moisture content.
