确认的成年素食者（98人）与生活在相同城市环境的匹配组非素食者进行对比，以评估动脉高血压的患病率。素食者的平均血压为126/77，对照组为147/88 （P < 0.05）。每10岁的人血压都明显降低。只有2%的素食者有高血压（血压160/95），而非素食者有26%的高血压。当比较相对体重相同的个体时，血压的差异也保持不变。两组高血压家族史相似。对饮用咖啡和吸烟等因素的分析显示，素食者的血压并没有降低。钠和钾的摄入量根据其与单个尿液样本中肌酐的比值进行评估。两组的钠排泄量相同，而素食者的钾排泄量明显更高。鉴于越来越多的证据表明钾在调节血压中起着重要作用，因此可以得出结论，素食中的保护性抗高血压因素是大量钾的存在。
Confirmed adult vegetarians (98) were examined against a matched group of nonvegetarians living in the same urban environment in order to evaluate the prevalence of arterial hypertension. The average blood pressure was 126/77 for the vegetarians and 147/88 for the control group (P < 0.05). Significantly lower blood pressure was found in every decade of age. Only 2% of the vegetarians had hypertension (> 160/95) as compared to 26% hypertensives in the nonvegetarians. These differences in blood pressure were maintained also when individuals with the same relative weight were compared. Family history of hypertension was similar in both groups. Analysis of factors such as coffee drinking and smoking did not favor reduced blood pressure among the vegetarian groups. Na and K intake were evaluated from their ratios to creatinine in a single urine sample. Both groups excreted the same amounts of Na, while K excretion was significantly higher in the vegetarians. In view of the increasing evidence that K plays an important role in the regulation of blood pressure it is concluded that the protective antihypertensive factor in the vegetarian diet is the presence of high amounts of K.
