Objective : Recurrent episodes of binge eating are a cardinal symptom of both bulimia nervosa (BN) and binge eating disorder (BED). However, the type of food consumed during binge eating varies among individuals. We investigated what types of foods were preferred by women with recurrent binge eating episodes, and compared the differences between BN and BED.
Methods : We selected 30 photographs, which included four different types of food to stimulate appetite : 1) desserts/snacks, 2) meat, 3) fruits/vegetables, 4) rice/pasta, and 5) stationary objects as a control condition. Each type was composed of six different items. After six hours of fasting, 39 participants (15 BN, 12 BED, and12 healthy controls) were instructed to score their appetite using Likert scales from 1 to 7 for each photograph.
Results : The BN group reported stronger appetite response to photographs of desserts/snacks, while the BED group and healthy controls reported stronger appetite response to photographs of rice/pasta and meat. Statistical analysis showed that the mean appetite rank to desserts/snacks were significantly higher in BN group compared to BED group and healthy controls (Kruskal-Wallis test ; BN=26.4 ; BED=19.2 ; Control=15.5 ; p=0.047). The differences between groups for other types of food were not significant.
Conclusion : Women with BN showed a stronger preference for desserts/snacks, while women with BED demonstrated no difference with the healthy control group. They ranked photographs of meat (beef, pork and poultry) highest. This uggests that there are different trigger foods contributing to binge episodes between bulimia nervosa and binge eating disorder.
