Nutrients and minerals are likewise needed in little amounts. Food gives energy and natural materials to develop and fix tissues. The water we take in assumes a significant part in metabolic cycles and forestalls the parchedness of the body. Our body can’t use bio-macromolecules in food in their unique structure.
