Antioxidants For People's Health
Antioxidants are substances that may protect your cells against the effects of free radicals. Free radicals are molecules produced when your body breaks down food, or by environmental exposures like tobacco smoke and radiation. Free radicals can damage cells, and may play a role in heart disease, cancer and other diseases. We've known for years that antioxidants can help prevent heart disease and cancer, reduce blood pressure and slow the effects of aging. These naturally occurring compounds protect the body from harmful, excess free radicals, sweeping them up before they can cause damage.
Antioxidant substances include：
- Beta-carotene
- Lutein
- Lycopene
- Selenium
- Vitamin A
- Vitamin C
- Vitamin E
Antioxidants are found in many foods. These include fruits and vegetables, nuts, grains, and some meats, poultry and fish. And the best way to lay an antioxidant-rich foundation that's inhospitable to toxins and free radicals is through a combination of whole foods.
