Wait, bring it back! Short- and longer-term effects of using foods and food images to enhance positive mood.
The hypothesis that eating a small portion of food will sustain a positive mood increase after viewing foods/food images was tested. Mood was measured at baseline, 5-min, and 10-min while participants viewed a food or an image of a food. Results showed positive mood change in all groups at 5-min. For groups who viewed an actual food, only when participants were allowed to eat a small portion at 5-min did mood remain positive at 10-min.
