An anonymous reader writes: Researchers at McGill University in Montreal have uncovered strong new evidence that that wildy-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.
