The evidence is compelling that red wine can be very beneficial to your health. In scientific tests on fungi, fish and mice, the compound resveratrol, which is found in red wine, has been shown to improve overall health and substantially prolong life.Resveratrol is a phytoalexin found in high concentrations in the skin of red grapes, which helps fight infections by fungi and certain bacteria. The molecule is thought to be an antioxidant, helping to prevent cell damage from powerful oxidants produced during normal metabolism. Although it is already touted as an “antiaging” drug, the mechanism by which it prolongs life in animals is unknown.
