How effective is dietary salt reduction on mortality and cardiovascular morbidity?
The methods of achieving salt reduction in the trials included in the review, as in other systematic reviews, were relatively modest in their impact on sodium excretion and on blood pressure levels. Such generally requires considerable efforts to implement and would not be expected to have a major impact on the burden of CVD. There was no information on participants’ health-related quality of life.
Cardiovascular disease is a major cause of premature death and disability. Data from observational studies have indicated a high dietary intake of salt is an important risk factor for cardiovascular disease.1
