The effect on blood pressure of an ovo-lacto-vegetarian (OLV) diet was assessed in a randomized controlled crossover trial. Fifty-eight mild untreated hypertensive subjects recruited from the Perth Centre for the 1983 National Heart Foundation (NHF) Risk Factor Prevalence Survey 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. A significant fall in systolic blood pressure, on average of the order of 5 mmHg, was associated with eating an OLV diet. Blood pressure change was unrelated to change in urinary sodium, potassium or body weight, but was related to initial blood pressures. Although an OLV diet may have an adjunctive role in control of mild hypertension, in view of likely problems with acceptability the dietary components responsible for the blood pressure changes need to be identified.
在一项随机对照交叉试验中评估了蛋奶素食（OLV）饮食对血压的影响。从珀斯中心招募的58名未经治疗的轻度高血压受试者参与了1983年国家心脏基金会（NHF）风险因素患病率调查，他们被随机分为三组：第一组在12周内维持其日常饮食；另外两组在12周试验的前6周或后6周接受OLV饮食。食用OLV饮食与收缩压显著下降有关，平均下降幅度约为5 mmHg。血压变化与尿钠、钾或体重的变化无关，但与初始血压有关。尽管OLV饮食可能在轻度高血压的控制中起辅助作用，但鉴于其可接受性可能存在的问题，需要确定导致血压变化的饮食成分。
