title: Bioactive polyphenols from grapes and wine emphasized with resveratrol.
abstract: Grape polyphenols are abundant. They play essential roles in the plant's life, particularly in defence mechanisms. Moreover, the grape, fresh or dried, is a widely consumed fruit by humans, as are its by-products, grape juice and wine. They also contain vast and highly varied quantities of polyphenols. Like other phytophenols, grape and wine resveratrol is considered a protective micronutrient. Resveratrol is a well known antioxidant, for example, a protector of low-density lipoproteins against oxidation. Its applications are therefore highly varied. Research supports the idea that wine consumed regularly, without excess, is a natural biological product possesses preventive properties, and not only well-known properties against vascular diseases (illustrated by the so-called French paradox). At least in experimental models so far, resveratrol prevents infections, inflammation, neurodegenerative diseases, and cancer. This review addresses whether the pro-longevity properties of resveratrol are preserved in the human species. If such is the case, it will be possible to imagine new ways of eating based on natural foods, with or without supplements, based on resveratrol. On the other hand, studies such as ours are investigating the synergies between resveratrol and some of the many polyphenols found in wine. These studies should fill in the gaps between the study of a molecule tested in isolation or in a binary system (e.g., with alcohol) and this same molecule in its biological context.
