Acute Effect of Eating Sweets on Alcohol Cravings in a Sample with At-Risk Drinking

BackgroundAlcohol craving, or the desire to drink alcohol, has been identified as a key experience preceding alcohol use. Alcoholics Anonymous has long claimed that individuals can allay alcohol cravings by eating sweets. Empirical tests of this strategy are limited to a few preclinical studies in rats, and there is no existing experiment testing the acute effect of eating sweets on alcohol cravings in humans.PurposeThe current study sought to experimentally test the acute effect of eating sweets on alcohol cravings in a sample with at-risk drinking.MethodsAfter being exposed to an alcohol cue, individuals with at-risk drinking (N = 150) were randomly assigned to eat sweets (n = 60), eat calorie-equivalent bland food (n = 60), or watch a video (n = 30). Caloric amounts were manipulated. Individuals with at-risk drinking were then exposed to a second alcohol cue. Changes in alcohol cravings from after the first to after the second alcohol cue were measured via visual analog scale and heart rate.ResultsThere were no significant between-group differences in changes in alcohol cravings. Caloric amounts did not modify effects.ConclusionsExperimental findings did not provide evidence to support the clinical lore that eating sweets can reduce alcohol cravings, albeit only acutely and for those with at-risk drinking. Other empirically supported strategies for managing alcohol cravings (e.g., pharmacotherapies, mindfulness) could instead be promoted
