The research community has long established that antioxidants are essential in maintaining a healthy body. These compounds help protect the body from the harmful effects of free radicals. Free radicals are unstable body molecules that lack electrons. These molecules steal electrons from the nearest healthy cell, which in turn makes the cell sick and prompts a chain reaction within the body. Free radical formation can be caused by exposure to toxins and pollution, smoking, and other environmental factors.
An article in the GlobalHealingCenter.com likens this process to cleaning a fish a tank. The fish tank resembles the body, while the gunk and grime that form in it at are the free radicals. Antioxidants act as bottom-feeder fishes that suck up all the dirt in the tank. In the same manner, antioxidants scavenge the body for free radicals and eliminate them by slowing down or inhibiting the body's oxidation process. High antioxidant levels in the body may help keep certain diseases in check such as cancer and cardiovascular diseases. Antioxidants were also associated with improved eye health, immune system and slower aging process.
