Abstract: Maladaptive eating is one of the greatest threats to health and well-being in the 21st century. Psychological factors that drive maladaptive eating are of interest as they may offer low-cost intervention targets. One such factor is negative affect. If negative affect does lead to maladaptive eating, interventions that reduce negative affect should lead to improved eating and food choice. One relevant class of techniques is affect regulation strategies. In the present research, we use survey data and a value-based decision-making task to demonstrate that negative affect is associated with maladaptive eating and food choice. We find that negative affect decreases the weight that participants place on the health benefits of food. We also show that teaching participants to use reappraisal to downregulate negative affect leads to healthier food choices. These findings indicate that reappraisal applied to incidental negative affect may be an effective method for improving eating and food choice.
