The effect of an ovo-lacto-vegetarian (OLV) diet on blood pressure was assessed in a randomized, controlled, crossover trial in 58 mild untreated hypertensive subjects recruited from the Perth Centre for the 1983 NHF Risk Factor Prevalence Survey. Subjects were randomly allocated to one of three groups; the first maintained their usual diet throughout 12 weeks; the other two were given an OLV diet for either the first or second 6 weeks of the 12-week trial. Introduction of an OLV diet was associated with a significant fall in systolic blood pressure, on average of the order of 5 mmHg, which was unrelated to change in urinary sodium, potassium or body weight. It was concluded that a vegetarian diet may have an adjunctive role in control of mild hypertension, but that in view of likely problems with acceptability those dietary components responsible for the blood pressure differences need to be identified.
在一项随机、对照、交叉试验中，对从珀斯中心招募的58名未经治疗的轻度高血压受试者进行了评估，以研究蛋奶素食（OLV）饮食对血压的影响，这些受试者来自1983年的国家健康与福利风险因素患病率调查。受试者被随机分为三组；第一组在整个12周内保持其通常的饮食；另外两组在12周试验的前6周或后6周接受OLV饮食。采用OLV饮食与收缩压显著下降相关，平均下降幅度约为5 mmHg，这与尿钠、钾或体重的变化无关。得出的结论是，素食饮食可能在控制轻度高血压方面具有辅助作用，但鉴于可能存在的可接受性问题，需要确定导致血压差异的饮食成分。
