先前的研究表明，大约40%到50%的人会在压力大的情况下增加食物消费。普遍的观点是，为应对压力而进食是一种不适应的自我调节。过去的研究主要集中在社会压力对饮食的负面影响上。我们认为，积极的社会体验也可能会调整饮食行为。在本研究中，参与者被分配到社会排斥、中立和社会包容的条件下。在随后的虚假品尝测试中，测量了冰淇淋的摄入量和与压力有关的习惯性饮食。在被社会排斥后，习惯吃得更多以应对压力的人(压力吞噬症)比习惯吃得更少以应对压力的人(压力吞噬症)吃得更多。相反，在融入社会后，应激性吞噬过度者的进食量明显少于应激性低吞噬者。目前的研究结果为在积极和消极情况下对食物消费进行互补调整提供了第一个证据。讨论了这些发现对压力和体重关系的影响。
Previous research suggests that approximately 40% to 50% of the population increase food consumption under stressful conditions. The prevailing view is that eating in response to stress is a type of maladaptive self-regulation. Past research has concentrated mainly on the negative effects of social stress on eating. We propose that positive social experiences may also modulate eating behavior. In the present study, participants were assigned to social-exclusion, neutral, and social-inclusion conditions. In a subsequent bogus taste test, the amount of ice cream eaten and habitual stress-related eating were measured. After being socially excluded, people who habitually eat more in response to stress (stress hyperphagics) ate significantly more than people who habitually eat less in response to stress (stress hypophagics). Conversely, after being socially included, stress hyperphagics ate significantly less than stress hypophagics. The present findings provide the first evidence for complementary adjustments of food consumption across positive and negative situations. Implications of these findings for the relationship of stress and body weight are discussed.
