Antioxidant vitamins protect the body from damage caused by harmful chemicals called oxygen-derived free radicals. Oxygen-derived free radicals are produced by normal cell function (metabolism). However, at high levels they can damage cells, including those in the lenses of your eyes, possibly leading to the formation of cataracts.
Eating foods with vitamins C and E appears to decrease your risk of some cancers and heart disease. Some studies show a decreased risk of cataracts in people who have high levels of vitamin E (an antioxidant) in their blood. Three studies are in progress to evaluate the relationship between antioxidants and cataracts. While studies indicate that antioxidants may protect against cataracts, their benefits have not been proven. 1
Foods that contain vitamin C include:
- Fruits such as berries, citrus fruits, and cantaloupe.
- Vegetables such as broccoli, green peas, and peppers.
Foods that contain vitamin E include:
- Vegetables such as avocados, kale, and sweet potatoes.
- Other foods such as peanuts, sunflower seeds, vegetable oils, and wheat germ.
