Diets High in Sugar and Butter Lead to Changes in Gut Microbiome Linked to Excessive Alcohol Intake in Mice

Mice that switched from a high sugar/butter diet to a standard diet developed a strong preference for alcohol over water, in a study exploring the connection between gastrointestinal microorganisms and alcohol use disorder (AUD). The findings may help lead to new treatments for AUD. Gut microbiota help maintain health, contributing to essential processes including immunity and metabolism. Gut microbiota maintain bidirectional communication with the brain via the gut-brain axis, such that a disturbance in one is linked to changes in the other. Studies involving animals and humans point to a highly complex relationship between microbiota disruption, metabolism, and alcohol use.
