An article at Scientific American suggests that excess salt is not particularly dangerous to human health:
This week 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.Reading such articles makes me think there’s no point in reading such articles: it seems that everything one knows turns out to be, at some point, wrong. (Smoke: good!) But what I know is that once one gets some distance from processed foods, they taste too dang salty.
