Antioxidants do not increase a person’s risk for developing melanoma, according to research conducted by Kaiser Permanente Northern California. The findings are contrary to the French study Supplementation in Vitamins and Mineral Antioxidants (SUVIMAX), which found that taking antioxidant supplements could increase the risk of developing skin cancer, especially in women.
The latest study, led by Kaiser’s Maryam Asgari, MD, looked at more than 60,000 men and women who reported their use of vitamin C, vitamin E, beta-carotene, selenium and zinc in the 10 years before the research began. The participants were also asked about risk factors for melanoma, including their family medical history and the frequency of sunburns.
After six years of similar dosage levels to the SUVIMAX study, 461 people had developed melanoma. The researchers found no association between taking supplements and the occurrence of melanoma among men or women. Asgari concluded that “antioxidants taken in nutritional doses do not seem to increase melanoma risk.”
Researchers working on the project indicated that there may have been flaws in the SUVIMAX methodology, which led them to inaccurately conclude that antioxidants may increase a person’s risk of developing melanoma. This begs a question that Nutrition Business Journal explored in our recently published 2009 U.S. Nutrition Industry Overview issue: Is some current dietary supplement research doing more harm than good?
