Résumé
Food and drugs from nature place a quite significant role in public healthcare system throughout the world. Nutraceuticals have evolved from the recognition of the link between food and health. Nutraceuticals contain health-promoting ingredients or natural components that have a potential health benefit for the body. Consumer interest in the relationship between diet and health has increased the demand for information on nutraceuticals. Rapid advances in science and technology, increasing health care costs, an aging population and rising interest in attaining wellness through diet are among the factors fueling interest in nutraceuticals. Nutraceuticals currently on the market represent a small fraction of the possible products. The vast potential for functional foods will not be achieved without extensive scientific research to ensure the safety and efficacy of these products.
