Functional foods can be defined as dietary items that, besides providing nutrients and energy, beneficially modulate one or more targeted functions in the body, by enhancing a certain physiological response and/or by reducing the risk of disease. Nutraceuticals are a group of products that are more than food but less than pharmaceuticals. Unfortunately, there is still no internationally accepted definition of these products therefore their judgment varies country by country. In most countries, nutraceuticals are taken as part of dietary supplements. The frequency of nutraceuticals use is 50%–70% in developed countries’ population and this number is increasing by age.
