To Be Taken With a Grain of Salt
“…a meta-analysis of seven studies involving a total of 6,250 subjects in the American Journal of Hypertension found no strong evidence that cutting salt intake reduces the risk for heart attacks, strokes or death in people with normal or high blood pressure. In May, European researchers publishing in the Journal of the American Medical Association reported that the less sodium that study subjects excreted in their urine—an excellent measure of prior consumption—the greater their risk was of dying from heart disease. These findings call into question the common wisdom that excess salt is bad for you, but the evidence linking salt to heart disease has always been tenuous.”
At the same time, however, this critical article does NOT cite any more convincing research to support the sodium argument.
Such a research project could take decades to deliver a meaningful result such as the ones from the Framingham Heart Study which, by the way, never attempted to study the impact of sodium chloride on high blood pressure and therefore heart disease. It’s probably too late now to retroactively study the data from the FHS to make a clear-cut determination about the real risks of salt intake…but that would have been very interesting.
This proves the point that ALL scientific research – and, in fact, all pubic statements of fact – need to be taken along with a suitably large helping of salt.
