Vitamin E 鈥榥o help against cancer, heart disease鈥
Print Edition
In yet another blow to the US$28 billion vitamin industry, a US task force on Monday urged against taking Vitamin E and beta-carotene to ward off heart disease or cancer.
The latest guidelines from the US Preventive Services Task Force update the 2003 edition by adding Vitamin E to beta-carotene, a supplement that was already known to be ineffective at preventing the two most fatal diseases in America.
The findings are based on a review of scientific studies which found that Vitamin E does not help — and that beta-carotene supplements could actually do more harm than good.
“Beta-carotene can be harmful as it increases the risk of lung cancer in people already at increased risk for the disease,” said Task Force co-chair Michael LeFevre.
With regards to other multivitamins, there was not enough evidence to say if they reduce or increase the chance of heart disease or cancer, the team said.
Despite numerous warnings about the unproven effects of vitamins, consumers continue to believe in them, with about half of US adults saying they take at least one dietary supplement and one-third reporting they take a multivitamin regularly.
Instead of taking supplements, the task force urged most people to simply eat a healthy diet rich in fruits, vegetables, whole grains, low-fat dairy and seafood.
“Cardiovascular disease and cancer have a significant health impact in America, and we all want to find ways to prevent these diseases,” said task force chair Virginia Moyer.
“However, we found that there is not enough evidence to determine whether taking single or paired nutrients or a multivitamin helps to prevent cardiovascular disease or cancer.”
The statement was published in the February 24 edition of “Annals of Internal Medicine.”
