Antioxidants
Treatment Overview
Antioxidants are natural chemicals that protect the body from damage caused by harmful molecules called free radicals. Many experts believe that this damage is a factor in the development of cancer and other conditions.
You are exposed to free radicals:
- Through by-products of normal processes that take place in your body. Examples include burning sugars for energy and releasing digestive enzymes to break down food.
- When the body breaks down certain medicines.
- Through pollutants.
Antioxidants include some vitamins (such as vitamins C and E), some minerals (such as selenium), and flavonoids, which are found in plants. The best sources of antioxidants are fruits and vegetables. You can find flavonoids in fruits, red wine, and teas. You can also buy antioxidant supplements. But it's best to get antioxidants from a healthy diet.
