Gut Inflammation Favors Adverse Food Reactions by Disrupting the Microbial Metabolism of Food Triggers.

Intestinal inflammation disrupts microbial food metabolism, promoting food sensitization and adverse reactions in mice and IBD patients.

• Why it matters: Understanding how gut inflammation influences food intolerance is crucial because it may explain the high prevalence of adverse food reactions in IBD patients and inform targeted therapies.
• What they did: Researchers used mouse models of intestinal inflammation and human fecal samples to analyze microbiota composition, food sensitization, and immune responses, including mast cell activity and microbial function.
• The result: Inflammation-driven depletion of food-metabolizing bacteria and disrupted microbial antigen metabolism are linked to increased food sensitization and adverse reactions, which can be mitigated by bacterial supplementation or mast cell stabilization.
