A new study says that few nutritional supplements can protect people from developing or dying from heart disease. The researchers say there is little evidence supporting the use of nutritional supplements. Yet about half of U.S. adults take at least one supplement to improve their health.
The researchers did find evidence that reduced use of salt was linked to a lower risk of dying from all causes among people with normal blood pressure. Some supplements also appeared to have a good effect on human health. Omega-3 fatty acids appeared to lower the risk of heart attack and heart disease in adults. Also, folic acid, a kind of vitamin B, appeared to lower the risk of strokes: blockages of blood flow that can damage the brain or cause death.
_______, the study suggested that combining calcium and vitamin D might increase the risk of stroke. The researchers said there was enough evidence to suggest that people should not start taking supplements if they want to prevent heart problems.
Eric Topol is an official with Scripps Research in La Jolla, California. He told the Reuters news agency that he agreed with the findings. “There are no convincing data that any vitamin or supplement reduces heart attacks,” he said. The lead author of the report was Safi Khan of the University School of Medicine in Morgantown, West Virginia. “People should focus on a healthy diet from nutritional food sources, not vitamins or supplements, in combination with healthy lifestyle which includes regular physical activities and not smoking,” he wrote.
