Antioxidants and Their Benefits

Antioxidants are useful in maintaining cell integrity. They bind to free radicals produced from oxidative reactions going on inside the body. The release of free radicals can have useful and harmful effects to the cells. Cells must undergo many important proceses in order to function properly. In most of these cellular reactions, release of free radicals often occur.  Although free radicals are useful in the defense of the body toward infection, their presence in large numbers inside the body can create changes in cells which are not in accordance to normal growth. Some affected cells can die or age prematurely, while others can develop changes that can result to cancer formation.

Antioxidants are agents that can neutralize the effects of free radicals inside the body, thus leading to healthy cell functioning. It acts by stopping the reactions that can lead to the production of free radicals. When the level of antioxidant is low in the body, oxidative stress often occur, leading to the production of many free radicals and eventually harmful cellular changes.
