You can protect yourself against both heart disease and cancer by getting more of the powerhouse vitamins E and C and the nutrient beta-carotene. All three can reduce your levels of free radicals, damaged molecules that cause harmful changes in the body. One theory holds that the aging process itself is the cumulative result of wear and tear form free radicals.
Unlike many other nutrients, vitamins E and C and beta-carotene are safe to take in amounts higher than the Recommended Dietary Allowance. “Since the risk is nil, it’s safe to take more,” says Jeffrey Blumberg, Ph.D., professor of nutrition at Tufts University. He suggests that optimal intakes for antioxidants may be in the range of 100 to 400 international units of vitamin E, 500 to 1,000 milligrams of vitamin C and 15 to 25 milligrams of beta-carotene every day.
