Understanding the benefits of red wine.

The study cited applies only, at this point, to yeast and to worms and flies, but resveratrol (a polyphenol found in red wine) seems to act to extend life span. Long term studies are underway in primates -- stay tuned. And in the meantime, make sure your diet and supplements include polyphenols!

"Scientists have suggested that resveratrol acts as an anti-oxidant, mopping up harmful free radicals that damage the cell. But Sinclair found the compound does not have strong antioxidant effects in yeast. 'The lifespan enhancing properties seem to depend more on SIR2 activation,' he says. Sinclair also believes this process is responsible for the human health benefits of drinking red wine."
