Resveratrol is a phytochemical found in a variety of plants, fruits and associated fruit products, including grapes, mulberries and blueberries. It has been linked to anti-aging, antioxidant and cardio protective benefits. Some scientists have hypothesized that it may be partially responsible for the "French Paradox," the seemingly low rate of cardiovascular disease among the French. A study conducted in 2008 found that resveratrol consumption similar to the amounts found in a pattern of normal wine consumption may have a positive outcome on ischemic cardiovascular disease. For 15 days, 20 healthy volunteers consumed 300mg of either red or white wine. There was evidence of inhibition of Reactive Oxygen Species (ROS) production and platelet formation, leading researchers to conclude that resveratrol may contribute the positive effects observed with wine consumption. Further research on the potential benefits and risks of resveratrol is warranted.
