The editorial couldn’t be clearer, with the title “Enough Is Enough: Stop Wasting Money on Vitamin and Mineral Supplements.” It was published in the prestigious journal Annals of Internal Medicine.
With respect to multivitamins, the studies published in this issue and previous trials indicate no substantial health benefit…Beta-carotene, vitamin E, and possibly high doses of vitamin A supplements are harmful,… Other antioxidants, folic acid and B vitamins, and multivitamin and mineral supplements are ineffective for preventing mortality or morbidity due to major chronic diseases.
Unfortunately, despite the growing evidence that most vitamins and supplements aren’t worth the money, the use of them continues to grow.
Despite sobering evidence of no benefit or possible harm, use of multivitamin supplements increased among U.S. adults…Sales of multivitamins and other supplements have not been affected by major studies with null results, and the U.S. supplement industry continues to grow, reaching $28 billion in annual sales in 2010.
In his book Whole: Rethinking the Science of Nutrition, Dr. Colin Campbell makes the case for why vitamins and supplements won’t give you the nutritional value of eating whole foods. He explains that your body breaks down whole foods and uses the nutrients it needs in their natural state, not when certain parts are separated from the whole. The complexity of the digestive system – which Campbell believes we will never fully understand – makes it imperative that in order to have good health you need to eat whole foods.
