Why do we need nutrients in our daily diet?

Carbohydrates, fat, protein, vitamins, and minerals are some important Nutrients that we have to involve in our diet because these nutrients help to build the body and furnish energy for doing work and for development. Through potato, rice, and sugar we get carbohydrates, through butter, cheese, and meat we get fat, through fish, egg, and milk we get protein and through green vegetables and fruits, we get vitamins and minerals.
