evidence: Recent research published in the Journal of the American Medical Association (JAMA) found that people following a low-salt diet for just one week may experience a significant reduction in blood pressure compared to a high-salt diet. [...] The link between low salt intake and improved blood pressure is well documented. This study showed that the link remains even for those on blood pressure-lowering medications. [...] Cutting down on salt is one of the best changes you can make to your diet to reduce your risk of high blood pressure. It is encouraging to see that blood pressure can improve when people start cutting back on salt.
