Are Low-Salt Diets Necessary (or Healthy) for Most People?

March 23, 2015

Researchers from the University of Copenhagen and myself recently analyzed 167 published trials that measured the effect on blood pressure from reduced sodium. We found that in the studies involving only subjects with normal blood pressure, sodium restriction had no significant impact. That means there is no scientific justification for a U.S. sodium policy directed at the entire population, because 65% to 70% of Americans have normal blood pressure and thus wouldn’t benefit from lowering their salt intake.
