Free radicals

Atoms that, as a result of a normal oxygen-related phenomenon, end up with a “free” electron; once they have reached this state, the atoms in question “oxidize” other atoms, causing chain reactions. It is believed that when the proliferation of free radicals exceeds the body’s ability to neutralize them, they play an important role in the aging and development of many diseases. Many scientists support the (unproven) theory that free radicals can cause cancer to develop. Antioxidants are substances that can neutralize or reduce the damage caused by free radicals in the body. open next page to see More
