Alone but together: Cloud‐based commensality benefits physical and mental health

Cloud-based commensality refers to an eating scenario in which people are eating and videoconferencing with remote co-diners. We report two experiments designed to investigate whether cloud-based commensality can exert a positive effect on individuals' physical and mental health. In Experiment 1, the participants were asked to rate their expectations concerning their feelings when eating in the context of cloud-based commensality or solitary eating and to make food choices in each eating scenario. In Experiment 2, romantic couples were recruited to have meals in different eating scenarios in the laboratory and were asked to rate their emotions and close relationships. The results of the two experiments revealed that when engaging in cloud-based commensality, participants reduced their intake of meat dishes but did not increase their choices of meat dishes compared to solitary eating. Moreover, the results suggest that cloud-based commensality can alleviate negative feelings and promote positive emotions during periods of quarantine or non-quarantine and enhance close relationships for romantic couples. These findings demonstrate that cloud-based commensality is beneficial for individuals' physical and mental health and provide practical implications for utilizing social eating to promote healthy eating.
