From broccoli to berries to tea, you’ve probably heard about the benefits of antioxidants in foods. Scientists are studying how antioxidant-rich foods may help prevent heart disease, cancer and other conditions that occur as we age. 

What are antioxidants? Just for a moment, think of your body as a car. It can rust when metal in the car reacts with oxygen. If you cover it with a protective coating, it doesn't rust as quickly. For the body, antioxidants are that protective coating. They protect your body's cells from damage caused by pollutants, smoke, unhealthy diets and the normal aging process.
