Resveratrol is found in red grape skins and is attributed to preventing the accumulation of fat, reducing insulin resistance, and lowering your risk for diabetes. Some researchers also believe that resveratrol can prevent the development of blood vessels needed to feed a tumor, and even stop breast cancer cells from growing by blocking the growth effects of estrogen. However, there are recent studies that indicate the opposite, that the risk for women predisposed to breast cancer increases with their intake of alcohol. It is true that resveratrol, which is also sold as a supplement, has many health benefits. But if you drink, and especially if there is a history of any kind of cancer in your family, we strongly suggest you talk with your doctor about the connection between alcohol consumption and cancer.
