Resveratrol clearly functions in the body as an antioxidant nutrient, and it also may have an important role to play as a phytoestrogen. Resveratrol is an exceptional phytonutrient that is found in grapes, cranberries, blueberries, peanuts, jackfruit, mulberries, bilberries, lingonberries, and a wide range of other non-food plants including flowers and trees.
Resveratrol is a phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Several experiments suggest that it triggers mechanisms that counteract aging-related effects in animals.
Resveratrol is present in a wide variety of edible plants, mainly in grapes and peanuts. The best way to increase intake of this antioxidant is to include red grapes, along with other resveratrol-containing foods, in your diet on a more regular basis.
Wine is the primary dietary source of resveratrol. Red wine contains much greater amounts than white wine, since resveratrol is concentrated in the grape skin and the manufacturing procedure of red wine includes extended contact with grape skins. Resveratrol is also available as a dietary supplement.
