高血压患者若将其食盐量降到平均摄入量的四分之一,则其血压可以明显降低.这种戒盐的方法对降低血压来说与服药的效果相同.这些发现是通过对20名患有所谓原发性高血压的病人进行了一年的试验所得出的结果.这项研究工作是由伦敦南部圣乔治医院的内科医生格雷厄姆·麦克格雷戈等人做的.研究人员对病人不加治疗观察了两个月,其平均血压为160/100mmHg(第一个数字表示收缩压,即心脏完全收缩时的压力;第二个数字表示舒张压,即当心脏松弛时的血压).
Hypertensive patients whose blood pressure was reduced to a quarter of their average intake had significantly lower blood pressure, a salt-forcing method that had the same effect as taking medication for lowering blood pressure, A year-old trial of patients with so-called essential hypertension, conducted by Graham McGregor, a physician at St George’s Hospital in South London, Patients were treated for two months without treatment, with an average blood pressure of 160/100 mm Hg (the first number indicates systolic pressure, the pressure at which the heart is fully contracted; the second number indicates diastolic blood pressure, that is, blood pressure when the heart is relaxed ).
