This paper assesses the extent to which consumers from the opposite poles of the socioeconomic distribution weigh three critical food attributes–healthiness, fillingness, and taste–, how they perceive the associations among them, and how differences in weights and associations influence food preferences. The results of a series of eight pre-registered studies in a highly unequal socioeconomic environment (Rio de Janeiro, Brazil) show that low (vs. high) socioeconomic status consumers are more likely to (a) choose unhealthy items even when supply-side factors (e.g., affordability and accessibility) are controlled by design, (b) trade healthiness for fillingness (but not taste), and (c) display stronger negative associations between the attributes (healthy = less filling; healthy = less tasty). These findings highlight the importance of a deeper understanding of the psychological differences in food preferences and perceptions and the use of such insights to design interventions aimed at mitigating nutritional inequality. In line with this rationale, the final set of studies shows that, albeit not being a trivial task, it is possible to increase healthy food choices among the disadvantaged by enhancing the fillingness of the healthy options available. Managerial and policy implications are discussed.

EXPRESS：社会经济地位如何影响食物偏好和观念


本文评估了来自社会经济分布两极的消费者对三个关键食品属性（健康、饱腹感和味道）的重视程度，他们如何看待它们之间的关联，以及权重和关联差异如何影响食物偏好。在高度不平等的社会经济环境（巴西里约热内卢）中进行的八项预先注册的系列研究结果表明，低（相对于高）社会经济地位的消费者更有可能 （a） 选择不健康的食物，即使供应侧因素（例如，可负担性和可及性）受到设计控制，（b） 用健康换取馅料（而不是味道），以及 （c） 在属性之间表现出更强的负关联（健康 = 较少填充;健康 = 不太好吃）。 这些发现强调了更深入地了解食物偏好和感知的心理差异的重要性，并利用这些见解来设计旨在缓解营养不平等的干预措施。根据这一基本原理，最后一组研究表明，尽管这不是一项简单的任务，但可以通过提高可用健康选择的填充性来增加弱势群体的健康食品选择。讨论了管理和政策影响。
