This doesn't mean that rodents were fed a malnutrition diet. But one fact of the experiment caught my eye. Rats only live about two years. But since monkeys live up to 40 years, that's a long time to wait for the results. Dr. Richard Weindruch at the University of Wisconsin is an eminent authority on animal aging.
Free radicals are the waste products of metabolism.
The theory is to get rid of as many free radicals as possible. The Affymetrix chip has helped to support the aging concept about free radicals. And with less energy there's less waste product and fewer harmful free radicals that trigger aging. In the meantime, we should all follow Weindruch's example. I'm eating less food.
