ObjectiveEating is often a social activity that can be influenced by others, particularly in close relationships when dietary preferences reflect underlying value differences. We sought to examine the personality traits of meat‐eating couples who differ in their preferences for meat.MethodWe recruited Swiss romantic couples in which one partner typically consumed more meat than the other (N = 272, couples = 136). At baseline, participants completed survey measures of self‐ and informant‐rated personality traits at the domain (e.g., agreeableness) and aspect level (e.g., compassion) and meat consumption. Participants then completed 28 daily meal surveys about their meat consumption.ResultsAmong high‐meat eating partners, those higher in openness/intellect and compassion ate less meat. Additionally, higher intellect among low‐meat eating partners predicted lower meat consumption among high‐meat eating partners.ConclusionsThese findings replicate evidence that personality plays an important role in meat‐eating and extend this evidence to meat consumption in a relational context.

恋爱伴侣在日常生活中的性格与肉类消费


目标饮食通常是一种可以受到他人影响的社交活动，尤其是在饮食偏好反映潜在价值观差异的亲密关系中。我们试图检查对肉类偏好不同的肉食夫妇的性格特征。方法我们招募了瑞士浪漫情侣，其中一方通常比另一方吃更多的肉 （N = 272，情侣 = 136）。在基线时，参与者在领域（例如宜人性）和方面层面（例如同情心）和肉类消费完成了自我和知情者评价的人格特征的调查测量。然后，参与者完成了 28 项关于他们肉类消费的每日膳食调查。结果在高肉食的伙伴中，那些开放性/智力和同情心较高的人吃肉较少。此外，低肉食伙伴的智力较高预示着高肉食伙伴的肉消费量较低。结论这些发现复制了人格在吃肉中起重要作用的证据，并将这一证据扩展到关系背景下的肉类消费。
