A new study indicates that few nutritional supplements appear to be effective in protecting people from developing or dying from cardiovascular disease. Researchers examined data from 277 trials with a total of almost 1 million participants to evaluate the effects of 16 different nutritional supplements and 8 dietary interventions related to heart problems and strokes. The majority of the diets, supplements, vitamins, and minerals failed to protect against heart attack or stroke or reduce the risk of death from heart-related causes, researchers report in the Annals of Internal Medicine. The researchers noted that roughly one-half of U.S. adults take some type of supplement despite a lack of evidence proving a clear benefit. "People should focus on healthy diet from nutritional food sources, not vitamins or supplements, in combination with healthy lifestyle which includes regular physical activity and not smoking," said Safi Khan, MD, lead study author and a researcher at West Virginia University School of Medicine in Morgantown.
