Which component of food does not provide any nutrients but is very important for the proper functioning of our body?
Roughage
Fibres are a kind of carbohydrate which are available in vegetarian food and cannot be digested by the body. They are mainly composed of cellulose. Though they provide no nutrients to the body, they help in the movement of undigested materials in the large intestine.
Raw fruits and vegetables are the best source of fibre, so salads can be made a part of everyday diet. Cereals containing bran, vegetables, and the stem and bud of the banana plant, etc., are also rich sources of fibre.
