Functional foods, also known, amongst other things, as FOSHU (foods for specific health use), pharmafoods, and nutraceuticals, are foods or beverages that provide medical or health benefits to the consumer. There are several high performance food ingredients that have been demonstrated to possess such health benefits including: Omega 3 for a healthier heart and circulatory system; folic acid which when taken during early pregnancy helps prevent neural tube defects in babies; and soya for both the cholesterol reducing properties of its proteins and the recently claimed anti-cancerous effects of its naturally occurring oestrogen, genistein.
