Lower salt intake likely to have had key role in plummeting cardiovascular disease deaths in past decade

Posted: 14 Apr 2014 04:14 PM PDT

The 15 percent fall in dietary salt intake over the past decade in England is likely to have had a key role in the 40 percent drop in deaths from heart disease and stroke over the same period, concludes research. But average intake across the nation is still far too high, warn the authors. And much greater effort is needed to curb the salt content of the foods we eat, they insist. Dietary salt is known to increase blood pressure, which is itself a major risk factor for heart disease and stroke.
