Question

Why should our food contain cereals, pulses, fruits and vegetables?

Answer 1

Hint:- Food is the main source of energy for living organisms. The energy that is gained through food can help to do the daily activities. The food that we consume contains carbohydrates, proteins, fats and vitamins.

Complete Answer:-
Food will be rich with the nutrient contents that are essential for the body’s function such as breathing, digestion, keeping the body warm and for the growth of the body. Plants are autotrophs that can synthesize their own food by the process of photosynthesis using sunlight, water and carbon dioxide. Plants produce food in the form of glucose. The leaves are known as the kitchen of plants.
Animals cannot synthesize their own food and are called heterotrophs. They mainly depend on plants for their food that serves as the source of proteins, carbohydrates, vitamins, etc. The source of food may be vegetables, fruits, cereals, meat or milk.
Protein containing foods include almonds, milk, broccoli, etc. Carbohydrates containing foods include starchy food vegetables, fruits, milk, etc. Vitamins are present in food items such as fruits, vegetables, eggs, milk, etc.
The deficiency of proteins can cause Kwashiorkor, also referred to as malnutrition. Vitamin deficiency will occur when enough vitamins are not sufficiently available for utilization. The deficiency of vitamins can cause malabsorption.
In order to supply vitamins and proteins, proper food that is rich with these nutrients should be taken that includes cereals, pulses, fruits and vegetables.

Note:- Other than vegetables and pulses, even meat is rich with many nutrients such as Vitamin B, Vitamin E, iron, zinc and magnesium. They can be supplied to the body via meat, poultry and eggs.
