They took bacteria from patients with anorexia and gave them to mice. The animals changed behavior

Research from the Czech Academy of Sciences reveals that gut microorganisms significantly influence the development and recovery from anorexia. Transferring microbiomes from patients to mice resulted in altered feeding behaviors, indicating a link between gut health and mental disorders. The study highlights the importance of restoring a healthy gut microbiome as part of anorexia treatment, suggesting that changes in gut bacteria may contribute to symptoms rather than being the primary cause of the disease. The findings emphasize the need for a holistic approach to recovery, addressing both psychological and biological factors.
