Free radicals are molecules naturally produced by your body when it's turning food into energy. Under normal circumstances, the body has the necessary mechanisms to control the activities of molecules. However, certain factors can lead to overproduction of free radicals., including:

Excess free radicals will attack the body, causing damage to important cellular molecules. Such damage can increase the risk of health problems like cancer, heart disease, arthritis, chronic fatigue syndrome, cataract formation and premature aging.

Antioxidants are very important because they can prevent free radicals from damaging the cells and tissues in our bodies. They help make us less susceptible to diseases and improve our overall health.

What Are Antioxidant Supplements?

If you're trying to get more antioxidants into your diet, antioxidant supplements may be an option. But the National Institutes of Health warns that some antioxidant supplements in high doses may be linked to health risks in some cases. For instance, beta carotene is an antioxidant supplement that may increase the risk of lung cancer in smokers. High doses of the antioxidant supplement Vitamin E may increase the risks of prostate cancer and one type of stroke.

What Are Antioxidant Food Sources?

When answering the question, 'What are antioxidants?', your doctor could simply answer: fruits and vegetables. There is good evidence that eating a diet that includes plenty of vegetables and fruits is healthy.
