essential nutrient
essential nutrient Those nutrients that are required by the body and cannot be synthesized in the body in adequate amounts to meet requirements, so must be provided by the diet: includes the essential amino acids and fatty acids, vitamins, and minerals. Really a tautology, since by definition nutrients are essential dietary constituents.
