One polyphenol that seems to have hogged the limelight is resveratrol, a compound found in a variety of foods such as the skin of red grapes, blueberries, peanuts and cocoa. Although few studies have examined the health benefits of resveratrol on humans, lab and animal studies have demonstrated that in high enough quantities, it can have anti-cancer and anti-inflammatory properties. Furthermore, it may bestow cardiovascular benefits because it has been shown to help prevent damage to blood vessels, reduce the amount of “bad” cholesterol in the body and prevent blood clots.
