80年前,Ambard等证明,限钠可降血压,另一些作者证实,摄入低盐(约10mmol/日)可明显降低绝大多数恶性高血压,Watins等指出,若重度高血压患者、每天盐摄入量由10mmo1/日增加至25—35mmol/日,则其血压高于治疗前水平。近年一些报告证实,适当的限盐可使轻至中度高血压患者降压。但是这些研究缺 Eighty years ago, Ambard et al. Demonstrated that sodium restriction can lower blood pressure. Other authors confirm that low salt (about 10 mmol / day) can significantly reduce the vast majority of malignant hypertension, Watins et al. Indicate that in patients with severe hypertension, daily Salt intake from 10mmo1 / day increased to 25-35mmol / day, then its blood pressure higher than the pre-treatment levels. In recent years, some reports confirm that proper salt restriction can reduce blood pressure in patients with mild to moderate hypertension. But these studies are missing
