- An antioxidant is a molecule capable of retarding or preventing the oxidation of other molecules . Oxidation reactions can produce free radicals that start chain reactions that damage cells. Antioxidants end these reactions by removing free radical intermediates and inhibit other oxidation reactions by oxidizing themselves.
- Antioxidants block the damaging effect of free radicals . Respiration in the presence of oxygen is essential in the cellular life of our organism, but as a consequence of it these free radicals are produced, which cause negative health effects throughout life through their ability to alter DNA (genes), proteins and lipids or fats.
- There are situations that increase the production of free radicals such as intense physical exercise, environmental pollution, smoking, infections, stress, diets rich in fat and overexposure to the sun.
- Antioxidants are found in foods such as vegetables, fruits, grain cereals, legumes, nuts and tea .
