Functional food

From Wikipedia, the free encyclopedia

Functional food or medicinal food is any fresh or processed food claimed to have a health-promoting or disease-preventing property beyond the basic function of supplying nutrients.^[1] The general category of functional foods includes processed food or foods fortified with health-promoting additives, like "vitamin-enriched" products. Fermented foods with live cultures are considered as functional foods with probiotic benefits.

Functional foods are an emerging field in food science due to their increasing popularity with health-conscious consumers.

The term was first used in Japan in the 1980s where there is a government approval process for functional foods called Foods for Specified Health Use (FOSHU).

[edit] Health claims

Functional food products typically include health claims on their label touting their benefits: for example: "Cereal is a significant source of fiber. Studies have shown that an increased amount of fiber in one's diet can decrease the risk of certain types of cancer in individuals."

Some countries, such as Canada, Sweden, and the United States, have specific laws concerning the labeling of such products. In the United States, the kinds of claims which are allowed are overseen and regulated by the Food and Drug Administration (FDA). However, some claims will fall outside of the purview of the FDA and be accompanied by the disclaimer: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease."

Such a disclaimer typically accompanies supplements rather than foods, but since the definition of functional food is still evolving and somewhat amorphous, a functional food may find itself bearing the warning.

[edit] Current Research

The Richardson Centre for Functional Foods and Nutraceuticals, which is part of the University of Manitoba, is the only centre of its kind, dedicated to the discussion, discovery, and development of functional foods and nutraceuticals, with a focus on the crops of the Canadian Prairies. Some current research projects examine: the effects of a diet rich in diaclyglycerol (DAG) oil on body weight, body composition, and blood lipid levels in women; the effect of Heart & Stroke Portfolio diet on lipid metabolism and weight loss in men; the effect of pulses and pulse fractions on indices of lipid, carbohydrate and energy metabolism, as well as oxidative status in overweight, hyperlipidemic individuals; the use of conjugated linoleic acid (CLA), an omega-3 fatty acid, as a nutraceutical for weight loss in humans; the evaluation of very long chain fatty acids/alcohol and plant sterols as functional food ingredients for cholesterol-lowering in hypercholesterolemic humans; the effects of dietary cholesterol with and without simvastatin on cholesterol absorption and synthesis and sterol profile in Smith Lemli Optiz syndrome (SLOS) patients; the effects of unique algal based polysaccharides on plasma lipid levels and energy metabolism in hamsters.

Dr. Peter Jones is a Canada Research Chair in Nutrition and Functional Foods and is the director of the centre. His research concerns itself with finding candidates for functional food ingredients and he does this by examining the efficacy of novel bioactive materials such as plant sterols -- natural components found in plants which can act as cholesterol-lowering agents.
