Nutrition and Functional Foods
Nutrition is defined as a science concerned with the role of food and nutrients in the maintenance of health, growth and reproduction of an organism. It comprises biosynthesis, absorption, excretion and assimilation. A modified food that claims to develop health or well- being by offering benefits and lowers the risk of chronic disease beyond that of traditional nutrients it contains. Functional foods may comprise such items as breads and cereals that are reinvigorated with herbs, vitamins and nutraceuticals. The term may also relate to qualities purposely bred into existing edible plants, such as purple or gold potatoes which have enriched anthocyanin or carotenoid contents.
