Stress is often associated with poor diet in young adulthood. However, very few studies have examined whether snacking on non-nutritious sweet or salty “comfort food” is directly linked with daily stress, a common intervention target. Further, trait mindfulness, a psychological resource that may be enhanced by psychological training and regular practice, has yet to be tested as a moderator of daily stress-eating linkages. This 11-day daily diary study examined multilevel linkages between daily stress appraisals and comfort food eating in undergraduates. Daily stress appraisals positively predicted comfort food eating at the between-, but not within-person, level. Mindfulness moderated these effects, such that only more mindful participants demonstrated a negative association between within-person stress and comfort food eating. Results illustrate that chronic stress exposure and acute stress reactivity relate differently to eating behavior. Mindfulness and chronic stress may be key intervention targets for non-clinical groups at risk for unhealthy eating.

正念减轻了日常压力并缓解了食品零食的联系：一个多层次的检查。

压力通常与成年后饮食不良有关。但是，很少有研究检查零食与非营养性甜味或咸味“舒适食品”是否与日常压力直接相关，而日常压力是常见的干预目标。此外，特质正念是一种心理资源，可以通过心理训练和常规练习得到加强，但尚未被作为日常饮食压力联系的调节者进行测试。这项为期11天的每日日记研究研究了大学生日常压力评估与舒适饮食之间的多层次联系。日常压力评估可以正面预测人与人之间（而不是人与人之间）饮食中的舒适食物。正念减轻了这些影响，因此只有更多的正念参与者表现出人际压力与舒适饮食之间的负相关关系。结果表明，慢性应激暴露和急性应激反应与进食行为不同。正念和慢性压力可能是面临饮食不健康风险的非临床人群的主要干预目标。
