p. 918. Functional foods, superfoods, and supplementslocked

  • David A. Bender

Abstract

When a vitamin or mineral deficiency is widespread in a population, a common approach is to enrich or fortify a staple food. ‘Functional foods, superfoods, and supplements’ defines functional foods as foods that contain one or more added ingredients to provide a positive health benefit, over and above the normal functions of food to provide nutrients and satisfy hunger. Superfoods are ordinary foods that are especially rich in nutrients or antioxidants and other potentially protective compounds, including polyunsaturated fatty acids and dietary fibre. ‘Nutritional supplements’ covers a wide range of preparations which are regarded as foods rather than medicines, and in most countries are regulated under food rather than under medicinal legislation.
