Want to slow aging? New research suggests it takes more than antioxidants

Don't put down the red wine and vitamins just yet, but if you're taking antioxidants because you hope to live longer, consider this: a new study published in the June 2010 issue of the journal Genetics casts doubt on the theory that oxidative stress to our tissues shortens lifespan. That's because researchers from McGill University in Canada have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer. The results contradict the popular theory that production of toxic reactive oxygen species in tissues is responsible for aging.
