This document discusses nutraceuticals and functional foods. It defines nutraceuticals as pharmaceutical-grade nutrients that are regulated by the FDA. Functional foods are designed to provide extra health benefits through enriched foods rather than supplements. They include foods fortified with added nutrients. Dietary supplements are concentrated nutrient products taken orally to supplement the diet, while functional foods are whole foods enriched with added nutrients. The document emphasizes the importance of nutrition in early life and a plant-based diet high in fruits and vegetables for reducing chronic disease risk.
