Administration of Fiber as a Dietary Supplement to Improve the Management of Alcohol Withdrawal

The goal of this clinical trial is to demonstrate that a fiber-enriched diet (with a high proportion of inulin and pectin) combined with standard care can reduce intestinal permeability in patients with alcohol use disorder (AUD) aged between 19 and 65. The hypothesis of our study is that a diet rich in different dietary fibers (mainly inulin and pectin), by modifying the gut microbiota and its metabolites, will induce a decrease in intestinal permeability, restore the composition of the gut microbiota and its metabolites, and further improve abstinence, levels of craving and anxiety, inflammation, steatosis, and hepatic fibrosis in patients with alcohol use disorder. The study consists of two parallel groups (a group eating fiber-rich snacks every day for 28 days (in addition to their usual care) versus a group not eating any snacks). Participants will be required to provide stool, blood, and saliva samples, and complete questionnaires.
