对健康女性低脂纯素饮食的可接受性进行定量评估，采用纯素饮食和无限制饮食的交叉设计，每一种饮食持续两个月经周期。在每个阶段进行为期三天的饮食记录和定量评估饮食可接受性和可感知的益处和不良影响的工具。研究对象是除了经期疼痛之外没有其他健康问题的女性，她们响应了一项基于社区的研究广告。在51名志愿者中，35人完成了这项研究。纯素饮食中大约10%的能量来自脂肪。参与者参加了每周的会议和烹饪示范。主要结局指标为营养摄入、饮食可接受性和可感知的益处或不良影响。统计分析包括对可接受性变量的Wilcoxon配对符号秩检验和对益处和不良影响的McNemar卡方检验。在素食阶段，能量、蛋白质、脂肪、胆固醇和钙的摄入量下降，而纤维摄入量上升。纯素饮食的可接受性与无限制饮食的可接受性在任何可接受性措施上都没有什么不同，除了需要付出的努力。在素食阶段，经常有体重减轻和能量增加的报道。低脂纯素饮食的好处促进了坚持。对许多人来说，饮食的可接受性并不是临床使用的障碍。
A quantitative assessment of the acceptability of a low-fat, vegan diet in healthy women was undertaken A crossover design using a vegan diet and an unrestricted diet, each lasting two menstrual cycles, was used. Three-day dietary records and a quantitative instrument rating diet acceptability and perceived benefits and adverse effects were administered in each phase. Subjects were women with no health problems other than menstrual pain who responded to an advertisement for a community-based study. Of 51 volunteers, 35 completed the study. The vegan diet derived approximately 10% of energy from fat. Participants attended weekly meetings and cooking demonstrations. The main outcome measures were nutrient intake, dietary acceptability, and perceived benefits or adverse effects. Statistical analyses consisted of a Wilcoxon matched-pairs signed-ranks test for acceptability variables and McNemar's chi-square for benefits and adverse effects. Energy, protein, fat, cholesterol, and calcium intake fell during the vegan phase, whereas fiber intake rose. The acceptability of the vegan diet was no different from that of the unrestricted diet on any acceptability measure, except for effort required. Perceived weight loss and increased energy were frequently reported during the vegan phase. Perceived benefits of a low-fat vegan diet facilitate adherence. For many individuals, diet acceptability is no barrier to its clinical use.
