Free Radicals May Not Be Cause of Aging

An anonymous reader writes "Researchers at McGill University in Montreal have uncovered strong new evidence that that wildly-accepted mitochondrial free radical theory of aging (MFRTA) is wrong. MFRTA suggests that free radicals cause oxidative damage, which in turn leads to the aging process. This new evidence shows that high levels of Reactive Oxidative species are rather a biological signal used to combat aging then the process itself. This goes against claims of major health benefits from consuming foods and particularly supplements that contain antioxidants."

Because natural stuff is coming from a system that evolved with humans since they populated the planet. Manufactured stuff isn't bad by default: but since artificial stuff is not tested for all the interactions with the substances that are already present in the environment to see long term effects, and it's produced in the name of profit (if you're less superficial in your view of society it's in the name of control), I'd go for natural stuff given the choice.

Of course natural stuff can be manufactured by the same people and with the same motivations as artificial stuff so the distinction is really between stuff made with love and stuff that screws people over but being natural is a factor not to overlook.
