The book discusses the legal rules on foodstuffs and medicines, and particularly on functional foods. Legal systems investigated are the EU and China. The study uses three Chinese berries as case examples of how product development faces regulation in practice. Consumer products with health-enhancing functions might legally be classified either as foodstuffs or medicines. The classification will depend on functions and presentation of the product. Safety of both foodstuffs and medicines is strictly regulated. Newly developed foods are called novel foods, and are specifically regulated. As regards marketing, foods are allowed to bear health claims, whereas medicines bear medicinal claims.
