Red wine may help to curb the effects of aging, with as little as a glass a day found to halt age-related changes in heart genes.
Scientists believe the discovery of the effects of a compound in the skin of red grapes may explain the so-called "French paradox" - where people living in regions of France where food is soaked in saturated fat have astonishingly healthy hearts and arteries.
Plant chemicals in red wine, which often accompanies French meals, have been suggested as a possible explanation, and the new study highlights one compound, resveratrol, which is known to have anticancer and antiinflammatory properties.
Previous research has shown that reducing dietary calories by 20-30% can extend lifespan and prevent genetic changes linked to aging in a range of animals. The new study, which looked at the effects on mice, indicated that low doses of resveratrol mimic the effects of calorie restriction to combat aging.
A glass of red wine, or food supplements containing even small doses of resveratrol, were likely to represent a "robust intervention in the retardation of cardiac ageing," the scientists at the University of Wisconsin-Madison in the US wrote in the online journal PLoS ONE.
A five ounce glass of muscadine red wine can contain as much as six milligrams of resveratrol. Smaller amounts of resveratrol are also found in blueberries, bilberries, cranberries and peanuts.
"Scietific researches these days either complement each other or supplement each other or totally oppose each other, in such circumstances these researches become not to be trusted. I throw a challange to research fraternity to come out clean of whatever you declare/ submit in the media/press. The researchers must understand their responsibility towards humanity. Today they say something tomorrow the other opposes the same. They just befool the humanbeings. Not at all acceptable." - Ramadhar, India
