Functional Foods
Functional foods and nutraceuticals are broad terms that describe foods, food ingredients or dietary supplements that demonstrate specific health or medical benefits, including the prevention and treatment of disease, beyond basic nutritional functions. These products include whole foods, food additives, vitamin and mineral supplements, herbs, phytonutrients, and probiotics. Nutraceuticals can be derived from plant, animal, marine and microbial sources.
A functional food is similar in appearance to, or may be, a conventional food that is consumed as part of a usual diet, and is demonstrated to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, i.e. they contain bioactive compound.

A nutraceutical is a product isolated or purified from foods that is generally sold in medicinal forms not usually associated with foods. A nutraceutical is demonstrated to have a physiological benefit or provide protection against chronic disease.
