Cheers to Red Wine and Resveratrol

June 25, 2009

One of the biggest discoveries in nutritional science is the identification of resveratrol, the active ingredient in red wine. This compound has been shown to dramatically increase the rate at which cells metabolize fat. Resveratrol stimulates the SIRT1 gene to produce a protein called sirtuin-1 which blocks a receptor on fat cells. When this receptor is blocked, the breakdown of fat is increased and the formation of new fat is decreased.

Other studies have shown that the stimulation of this protein by resveratrol also activates the genes that promote a longer, healthier lifespan. Resveratrol comes from the skin of grapes but since it oxidizes quickly (losing its metabolic effect in the process) fresh grapes and white wine are less effective sources. Red wine is a unique source of resveratrol as it retains the same amount as was in the grape at the time of fermentation.

Doctors are excited about resveratrol as a substance that seems to mimic the life-lengthening effects of calorie restriction without dieting. So there will definitely be more research and news about the effects of resveratrol in the near future.
