Resveratrol is a phytoalexin (antibiotics produced by plants that are under attack) found in the skin of red grapes and as a constituent of red wine. Resveratrol and other grape compounds have been positively linked to fighting cancer, heart disease, degenerative nerve disease, and other ailments. Red wine typically has health benefits not found in white wine (with some exceptions) because many of these compounds are found in the skins of the grapes and only red wine is fermented with the skins.
