AntioxidantsWednesday, May 05, 2010
Antioxidants are substances or nutrients in our foods which can prevent or slow damage to our body. Researchers believe they enhance immune defense and therefore lower the risk of cancer and infection. Dr. Edward Hill discusses antioxidants in todays 60 Second Housecall.
Antioxidants protect the body from damage caused by harmful molecules called free radicals. Many experts believe free radicals are a factor in the development of heart disease, stroke and cancer.
Free radical production is actually a normal part of life. The bodys natural defense systems neutralize free radicals, rendering them harmless.
Exposure to ultraviolet radiation, or pollutants and alcohol can overpower the bodys ability to neutralize free radicals, allowing them to damage the bodys cells.
Antioxidants include vitamins such as C and E; minerals, such as selenium; caratenoids such as beta-carotene; and flavonoids, found in fruits, red wine and some teas. You can also buy antioxidant supplements, but the best sources of antioxidants are natural fruits and vegetables.
Consuming more antioxidants helps provide the body with tools to neutralize harmful free radicals. A balanced diet rich in colorful fruits and vegetables can provide you with immediate health and energy benefits and help fight the effects of aging for years to come.
