Nutrients from Food More Beneficial than Supplements, According to Study

A study led by researchers at Tufts University, published in Annals of Internal Medicine, revealed that adequate intake of nutrients from food is associated with a reduction in mortality, but there is no association between use of dietary supplements and a lower risk of death. The study evaluated the association between dietary supplement use and death from all causes, cardiovascular disease, and cancer in 27,000 U.S. adults. Researchers found that adequate intakes of Vitamin A and Vitamin K, as well as magnesium and zinc, from food were associated with lower risk of death, but the same did not hold true when these nutrients were sourced from supplements. Furthermore, excess calcium intake from supplements was associated with higher risk of death from cancer, although there was no association for calcium intake from foods.
