We age because our cells are oxidized. It is a natural process but we can have influence it through our diet. EVOO is one of the best allies to combat that oxidation.
An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation is a natural and necessary process of life, however, antioxidants help us to combat oxidative stress, which occurs when in the oxidation there is an imbalance between pro-oxidant (free radical) and antioxidants .
Many ingredients that are part of our diets have both of them, and when trying to find that balance is where the richness in polyphenols and tocopherols (vitamin E) that EVOO has, can help us.
Aging is explained, among other theories, as the result of depletion of protective systems of the organism against free radical pro-oxidants. That is why in aging related diseases such as dementia (AD), Parkinson, rheumatoid arthritis, etc., a diet high in antioxidants can help prevent and delay their onset and effects.
