Resveratrol, a powerful natural antioxidant, shows potential for increasing longevity and preventing heart disease, cancer and brain disease. Ancient teachings dating back nearly 5,000 years allude to the heart-fortifying effects of grapes and their juices. Today, science has linked grapes and other foods containing resveratrol to an amazing and varied list of health benefits. Resveratrol's incredible possible health benefits range from antioxidant, anti-inflammatory, antiviral and antibacterial properties. Many foods are rich, natural sources of resveratrol, including red wine, dark chocolate, red grapes, peanuts, pistachios and many berries. Resveratrol supplements are also widely available and promise to deliver the same health benefits as red wine.
