Salt: How much less should we eat for health? Understanding the recent I0M report

摘要

The Institute of Medicine (IOM) released a report in May that reviewed the evidence on the effects of low sodium intake on health1. It supported a population-wide lowering of sodium from the current average of about 3400 mg/day; but it did not lend support to current dietary guidelines, which have been in place since 2005. These recommend lowering of sodium intake to less than 2300 overall but to 1500 mg/day among certain subgroups, including all those over 50 years of age, African Americans, and those with hypertension, diabetes, or chronic kidney disease. Not surprisingly, the IOM report has caused much consternation in the press.
