In the 1990s, antioxidants became famous as the nutritional equivalent of the fountain of youth. Increasing your intake of vitamin C, vitamin E, beta-carotene, and selenium was promoted as an easy and painless way to prevent cancer, heart disease, vision problems, Alzheimer’s disease, arthritis, and many other illnesses.

Unfortunately, recent research has put a damper on this excitement. It now appears that antioxidant proponents had jumped the gun. In fact, these supplements may have little benefit for these purposes. Worse still, some may even increase the risk of cancer and heart disease.
