Regulate metabolism, maintain normal growth and cell function. Fat soluble (a, d, e, k) or water soluble (b1 thiamine, b2 riboflavin, b3 niacin, B5 pantothenic acid, b6 pyridoxine, b7 biotin, b9 folic acid, b12 cobalamin, c ascorbic acid) Components of muscles, tissues, bones, life supporting systems (oxygen transport, enzymes, dna structure) Need large amounts (calcium, phosphorus, magnesium, sodium, potassium, sulfur and chloride) Need small amounts (iron, zinc, iodine, copper, manganese) Trace chemicals in foods that are not fiver, macronutrients, or micronutrients. Sufficient energy to keep weight in a desirable range. Proper types and balance of macronutrients, micronutrients, water, and phytochemicals. Nutrient composition in food relative to energy content.
