Overview

• Mice fed pork, beef or mutton daily for two weeks developed more severe DSS‑induced colitis than controls.
• Red meat diets reduced Akkermansia, Faecalibacterium, Streptococcus and Lactococcus and increased Clostridium and Mucispirillum in the gut.
• Colonic tissue showed greater infiltration of neutrophils and macrophages along with elevated pro‑inflammatory cytokines after red meat feeding.
• The peer‑reviewed research from Capital Medical University was published in Molecular Nutrition & Food Research.
• Authors caution that findings from a short, high‑exposure murine model may not translate directly to people and suggest reducing red meat intake pending human studies.
