钠盐在血压调节中起重要作用,它是高血压发病的一个危险因素。近年流行病学提示摄盐量和高血压发病率呈正相关,如果减少盐的摄入量,可使血压下降。过多钠盐的摄入,使细胞外液扩张,通过中枢及周围循环调节机制而致血压增高,一般认为24小时尿钠排量低于120毫克当量,不易得高血压。 Sodium salt plays an important role in the regulation of blood pressure and is a risk factor for the development of hypertension. In recent years, epidemiological evidence of salt intake and hypertension incidence was positively correlated, if reduced salt intake, blood pressure can be reduced. Too much sodium intake, the expansion of extracellular fluid through the central and peripheral circulation regulation mechanism caused by increased blood pressure, generally considered 24-hour urinary sodium output lower than 120 milligrams equivalent, not easy to get high blood pressure.
