Free radicals are groups of charged atoms, which are characterized by having one or more unpaired electrons (e-) in its outer shell capable of mating, so they are very reactive and unstable and are usually oxygen; these are released when food is metabolized in our cells to produce energy. , The result of these reactions produces a disruption in the cell walls of the organism; this disorder is lethal to the cell. Free radicals are produced by most cells in the body through its own cellular metabolism and also by the action of toxic agents. In the presence of these, the body must neutralize, to avoid injury to the tissues, but the problem appears when the concentration of these free radicals is very high, affecting our state of health.

According to an article published on the internet "Biological life is free radical microseconds, but has the ability to react to everything around him causing great damage to molecules and cell membranes. Free radicals are not inherently bad. In fact, our own bodies are manufactured in moderate quantities to fight bacteria and viruses. Free radicals produced by the body to carry out certain functions are easily neutralized by our own system. To this end, our body produces enzymes (such as catalase, dismutase and the superoxide dismutase) that are responsible for neutralizing them. These enzymes have the ability to disarm free radicals without destabilizing their own state. The chemical reactions of free radicals are constant in the cells of our body and are necessary for health. But, the process must be controlled with proper antioxidant protection. Our body is fighting free radicals every moment of the day. Our health problem occurs when our body has to withstand excessive free radicals during years mostly produced by external contaminants enter our body pollution products. "

In short, to prevent disease and aging caused by excess free radicals our bodies, there to lead a healthy life, a good diet, avoiding cigarette consumed, exercise and avoid saturated fats, which produce increased cholesterol contributing to high dangerous disease of arteriosclerosis, have also been linked to many chronic free radical as Alzheimer's, hepatitis, hypertension, rheumatoid arthritis, lupus, diabetes mellitus, periodontal disease, chronic renal failure and many others, But there also keep in mind that adequate amounts have benefits, such as the fight against bacteria and viruses, regulate the function of proteins, control muscle tone, etc…
