Forty-eight people with hypertension entered a controlled study to observe the effect of sodium (NaCl) restriction on blood pressure. In people with mild hypertension (diastolic blood pressure 90-105 mmHg), sodium restriction reduced blood pressure compared with a control group and 75% obtained a diastolic blood pressure of less than 90 mmHg. In people with more severe hypertension (diastolic blood pressure 4105 mmHg), sodium restriction achieved the same level of control as chlorothiazide (500 mg a day). Restriction of sodium intake is an effective method of reducing blood pressure and should be the first form of therapy in people with mild hypertension.
48名高血压患者进入一项对照研究，以观察限制钠（氯化钠）摄入对血压的影响。在轻度高血压患者（舒张压90 - 105 mmHg）中，与对照组相比，限制钠摄入可降低血压，75%的患者舒张压降至90 mmHg以下。在重度高血压患者（舒张压＞105 mmHg）中，限制钠摄入与氯噻嗪（每日500 mg）达到相同的控制水平。限制钠摄入是降低血压的有效方法，应作为轻度高血压患者的首选治疗方式。
