Resveratrol, an antioxidant compound found abundantly in red wine and red grapes, exerts beneficial effects on the body’s circulatory function. Peter Howe, from University of South Australia (Australia), and colleagues studied a group of 28 obese men and women with mild hypertension (high blood pressure), who were given a daily supplement of 75mg resveratrol. After six weeks, the researchers observed that vasodilator functions, as measured by flow-mediated dilatation (FMD), improved by 23%. The study authors explain that FMD is an accepted parameter for the risk of cardiovascular disease and cognitive decline.
