随着越来越多的证据表明与植物性饮食相关的积极健康结果，该研究的目的是研究将青少年的食物选择转向植物性食物的潜力。使用学校食堂的真实的世界设置，在英格兰约克郡的一所中学中设计和部署了一组对选择架构的小变化。针对指定的食品项目（整个水果，水果沙拉，素食每日特色菜，三明治沙拉）的变化实施了六个星期。收集到的关于学生食物选择的数据（218 796次交易）使学生（980名学生）的选择得以审查。学生的食物选择在三个阶段进行比较：基线（29周）;干预（6周）;和干预后（3周）。与基线相比，干预期间和干预后期间指定食物的选择显著增加（基线，1.4%;干预3.0%;干预后，2.2%）（2）（2）= 68.1，p < 0.001。逻辑回归模型也揭示了干预的独立效果，与基线相比，学生在干预期间选择指定食物的可能性是2.5倍（p < 0.001）。这项研究的结果指出了选择架构在中学环境中的影响，以及它在改善青少年日常食物选择方面的潜在作用。
With growing evidence for the positive health outcomes associated with a plant-based diet, the study's purpose was to examine the potential of shifting adolescents' food choices towards plant-based foods. Using a real world setting of a school canteen, a set of small changes to the choice architecture was designed and deployed in a secondary school in Yorkshire, England. Focussing on designated food items (whole fruit, fruit salad, vegetarian daily specials, and sandwiches containing salad) the changes were implemented for six weeks. Data collected on students' food choice (218,796 transactions) enabled students' (980 students) selections to be examined. Students' food choice was compared for three periods: baseline (29 weeks); intervention (six weeks); and post-intervention (three weeks). Selection of designated food items significantly increased during the intervention and post-intervention periods, compared to baseline (baseline, 1.4%; intervention 3.0%; post-intervention, 2.2%) (2)(2) = 68.1, p < 0.001. Logistic regression modelling also revealed the independent effect of the intervention, with students 2.5 times as likely (p < 0.001) to select the designated food items during the intervention period, compared to baseline. The study's results point to the influence of choice architecture within secondary school settings, and its potential role in improving adolescents' daily food choices.
