Decades of dietary research have shown that foods rich in antioxidants—such as many vegetables and fruits—may help to protect against chronic diseases such as heart disease and cancer. These observations prompted researchers to conduct studies to test whether antioxidant supplements, including vitamin C, vitamin E, and beta-carotene supplements, could also help prevent these diseases.
These studies found that antioxidant supplements didn’t reduce the risk of heart disease or cancer. And there was evidence that the supplements might even increase disease risk in some instances. In particular, supplements containing beta-carotene were linked to an increased risk of lung cancer in smokers.
Some key points to remember: - Vegetables and fruits are healthful foods.
- High-dose antioxidant supplements might be harmful.
- Research on antioxidants and other substances in food that might have health benefits is continuing.
