New study questions salt-heart disease link
Rod S. Taylor of the University of Exeter in Britain and his colleagues conducted a systematic review of the scientific literature for the Cochrane Collaboration, an independent international organization of researchers that analyzes the evidence for medical questions.
A major new scientific analysis is raising questions about the link between salt consumption and heart disease.
In an article published in the American Journal of Hypertension , the researches identified seven studies involving about 6,257 adults with normal or high blood pressure who reduced the amount of salt in their diets. When they pooled the data to conduct a “meta-analysis”of the studies, the researchers found no clear evidence that cutting salt cut the chances of dying from heart disease or dying for any other reason, the researchers reported.
