Americans who eat a diet high in sodium and low in potassium have a 50 percent increased risk of death from any cause, and about twice the risk of death from heart attacks, according to a study published today in the Archives of Internal Medicine. The study was conducted by researchers at the Centers for Disease Control and Prevention, Emory University and Harvard University.
This is the first study to examine, using a nationally representative sample, the association between mortality and people's usual intake of sodium and potassium. The study analyzed data from the National Health and Nutrition Examination Survey (NHANES), a survey designed to assess the health and nutritional status of adults in the United States. Usual intake of sodium and potassium is based on dietary recall.
