Panel finds no benefit in sharply restricting sodium

NEW YORK — In a report that undercuts years of public health warnings, a prestigious group convened by the government said there is no good reason based on health outcomes for many Americans to drive their sodium consumption down to the very low levels recommended in national dietary guidelines.

Those levels, 1,500 milligrams of sodium a day, or a little more than half a teaspoon of salt, were supposed to prevent heart attacks and strokes in people at risk, including anyone older than 50, blacks, and people with high blood pressure, diabetes, or chronic kidney disease — a group that makes up more than half of the US population.
