The Salt Substitute and Stroke Study (SSaSS): a large-scale cluster randomised controlled trial to assess whether sodium reduction, achieved through salt substitution, prevents stroke.

过量的食盐会导致高血压，而高血压是中风的主要原因。已经清楚地表明，通过药物治疗降低血压水平可以降低中风的风险。另一种不用吃药就能降低血压的方法是少吃盐，但这是否也能预防中风还不确定。盐替代品和中风研究涉及20,996人，随访5年，将回答这个问题。

Excess dietary salt causes high blood pressure and high blood pressure is a major cause of stroke. It has been clearly showed that lowering blood pressure levels with drug therapies reduces stroke risk. Another way of lowering blood pressure without having to take drugs is to eat less salt, but whether this also prevents stroke is uncertain. The Salt Substitute and Stroke Study that involves 20,996 people followed for 5 years will answer this question.
