Resumen de Food restriction and the experience of social isolation

• Across 7 studies, food restrictions increased loneliness by limiting the ability to bond with others through similar food consumption. We first found that food restrictions predict loneliness using observer- and self-reports among children and adults (Studies 1–3). Next, we found mediation by the experience of worry and moderation by eating similar food as others. When restricted individuals were unable to bond over a meal (i.e., they ate different vs. the same food as others), they worried. These “food worries” mediated the effect of restrictions on loneliness (Studies 4 and 5). Moving to controlled experiments, manipulating the presence of a food restriction for unrestricted individuals increased reported loneliness (Study 6). This effect replicated in an experiment that capitalized on a naturally occurring food restriction—the holiday of Passover—where Jewish observers were restricted from eating chametz (leavened food; Study 7). Overall, while both food restrictions and loneliness are on the rise; this research found they may be related epidemics. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
