[Oxidative stress, diseases and antioxidant treatment].
Oxidation is a biochemical process of loss of electrons associated with another of reception called reduction. This process is capital for life, because it takes part in the production of cellular energy. Oxidative stress appears when oxidation is excessive. This reality is complex in all biological levels, and cannot be measured or defined by a single parameter. A great number of diseases have been related to oxidative stress and generation of free radicals. For this reason, antioxidant therapies and diets (such as mediterranean diet) rich or enriched with antioxidants seem to prevent or at least to attenuate the organic deterioration originated by an excessive oxidative stress.
