nutraceuticals, mostly phytochemicals derived from dietary or medicinal plants such as soya bean, garlic, ginger, tea as well as propolis, honey and others, may have chemopreventive activities, as already suggested by epidemiologic and animal model studies. their ability to reduce cancer incidence in these studies is likely related to apoptosis.

Dr Stephen DeFelice coined the term "Nutraceutical" from "Nutrition" and "Pharmaceutical" in 1989. The term nutraceutical is being commonly used in marketing but has no proper definition. An attempt to redefine nutraceuticals and functional foods is made in this article. The proposed definitions can help distinguish between functional foods, nutraceuticals, and dietary supplements. The advantag...

Nutraceuticals are food components or active ingredients present in foods and used in therapy. This article analyzes the characteristics of the molecules with a lipid-lowering effect. The different nutraceuticals may have different mechanisms of action: inhibition of cholesterol synthesis primarily through action on the enzyme HMG-CoA reductase (policosanol, polyphenols, garlic and, above all, ...

Nutraceuticals are natural and commonly found in bioactive foods or whole plants to keep energy balance in the body and promise substantial therapeutic value in cardioprotection. Major cardioprotective bioactive foods and nutraceuticals are now part of nutrition supplements at nonprescription counters and their self-prescription is increased at large scale. The literature suggests the growing u...

Nutraceuticals are important natural bioactive compounds that confer health-promoting and medical benefits to humans. Globally growing demands for value-added nutraceuticals for prevention and treatment of human diseases have rendered nutraceuticals a multi-billion dollar market. However, supply limitations and extraction difficulties from natural sources such as plants, animals or fungi, restr...

Background Nowadays, growing attention was being given to the alternative ways to prevent or treat diseases. Nutraceuticals are used increasingly for this purpose. Many of these are being used as alternative therapy. Classic therapy with synthetic drugs, although very effective, has many side effects. The term "nutraceuticals" refers to the link between the nutritional and pharmaceutical domain...

Current and potential regulations of functional foods (nutraceuticals) will be discussed with emphasis on those features differentiating nutraceuticals from drugs. Current practices in nutraceutical development and limitations on their marketing and acceptance will be summarized. Comparisons between development and marketing strategies used for herbal and plant products and those used for nutra...

Nutraceuticals are natural and bioactive products with food value to keep energy balance in the body and promise substantial therapeutic value in several diseases. Major nutraceuticals are now part of nutrition supplements at nonprescription counters and their self-prescription is increased at large scale. The current literature suggests the nutraceutical use in most of cancer prevention and ma...

Currently, nutraceuticals do not have a specific definition distinct from those of other food-derived categories, such as food supplements, herbal products, pre- and probiotics, functional foods, and fortified foods. Many studies have led to an understanding of the potential mechanisms of action of pharmaceutically active components contained in food that may improve health and reduce the risk ...
