May 16, 2008 — Contrary to long-held assumptions, high-salt diets may not increase the risk of death, according to investigators from the Albert Einstein College of Medicine of Yeshiva University. They reached their conclusion after examining dietary intake among a nationally representative sample of adults in the U.S.
The Einstein researchers actually observed a significantly increased risk of death from cardiovascular disease (CVD) associated with lower sodium diets. They report their findings in the advance online edition of the Journal of General Internal Medicine.
The researchers analyzed data from the Third National Health and Nutrition Examination Survey (NHANES III), which was conducted by the federal government among a nationally representative sample of U.S. adults. These data were then compared against death records that had been collected by the government through the year 2000.
The sample of approximately 8,700 represented American adults who were over 30 years of age.
