[Aging and free radicals].
Several theories on aging are presented. All of them give important contributions but none explains all the aspects of the problem. Oxygen radicals produced during cellular combustion contribute to aging through multiple cumulative microlesions throughout life. The importance of glucose is emphasized; it forms early and late Maillard compounds. Other causes of aging are discussed.
