Free Radicals and Oxidative Stress
Free radicals are molecules that are missing one electron. They are produced by the body when exposed to toxins in the environment present in the air, water, and food. The missing electron causes these molecules to be unstable, and this instability causes damages to nearby cells. Antioxidants are known to neutralize free radicals, and research is underway to attempt to discover if certain vitamins could be helpful in preventing or slowing the development of cataracts.
