Communal eating, whether in feasts or everyday meals with family or friends, is a human universal, yet it has attracted surprisingly little evolutionary attention. I use data from a UK national stratified survey to test the hypothesis that eating with others provides both social and individual benefits. I show that those who eat socially more often feel happier and are more satisfied with life, are more trusting of others, are more engaged with their local communities, and have more friends they can depend on for support. Evening meals that result in respondents feeling closer to those with whom they eat involve more people, more laughter and reminiscing, as well as alcohol. A path analysis suggests that the causal direction runs from eating together to bondedness rather than the other way around. I suggest that social eating may have evolved as a mechanism for facilitating social bonding.
无论是在盛宴上还是与家人或朋友共进日常餐食,群体聚餐都是人类共有的行为,但令人惊讶的是,它在进化方面很少受到关注。我利用英国一项全国分层调查的数据来检验这样一个假设:与他人一起用餐能带来社会和个人层面的益处。我发现,那些更频繁参与社交聚餐的人感觉更幸福,对生活更满意,更信任他人,更融入当地社区,并且有更多可以依靠获得支持的朋友。导致受访者感觉与一起用餐的人关系更亲密的晚餐,参与人数更多,笑声和回忆更多,还会饮酒。路径分析表明,因果方向是从一起用餐到建立亲密关系,而不是相反。我认为社交性用餐可能是作为一种促进社会联系的机制而进化出来的。
