Those of you who pay attention to anti-aging research may have noticed that the free radical theory has been under fire lately.  Now a new study on free radicals in worms is landing yet another blow on the already beleaguered theory.

“These findings challenge our understanding of how free radicals are involved in the aging process,” Hekimi said. “The current theory is very neat and logical, but these findings suggest a different framework for why oxidative stress is associated with aging.” The genetically modified worms demonstrated that the production of free radicals can help to trigger the body’s general protective and repair mechanisms. In other words, at certain stages in life, free radicals may be a key part of our well-being, despite their toxicity.

It should be said that free radicals are indeed toxic but in this case it seems to be an example of the dose making the poison.
