Several studies have come out touting the power of resveratrol in fighting various types of cancer in many different stages. Research from University of Leicester found that resveratrol intake equal to two glasses of red wine cut the rate of bowel tumors in half in laboratory models. "One of the reasons it helps prevent cancer is it reduces damage to DNA, which is the beginning of cancer," says Robinson. However, alcohol consumption has also been shown to increase the occurrence of certain cancers. This conundrum has prompted researchers to try and find alternative ways to take in resveratrol, such as eating fresh currants or grapes.
