New research\u00a0sheds light on\u00a0why red meat may worsen\u00a0inflammatory bowel disease\u00a0(IBD) – and how\u00a0other\u00a0protein\u00a0sources\u00a0could help protect the gut.\u00a0<\/p>\n
In a new study published to publish in\u00a0Cellular and Molecular Gastroenterology, researchers found that mice\u00a0fed\u00a0a beef-based diet developed the most severe intestinal inflammation<\/a>. At the same time,\u00a0those consuming pea protein showed only mild symptoms.\u00a0<\/p>\n IBD cases have risen in the U.S. and worldwide over recent decades, alongside increased consumption of animal protein, including red meat.\u00a0Previous\u00a0studies have linked red meat intake to a higher risk of developing or relapsing IBD, but the biological reasons have\u00a0remained\u00a0unclear.\u00a0<\/p>\n Alternatives\u00a0could help protect the gut. While evidence-based dietary guidance for IBD\u00a0remains\u00a0limited, scientists found that mice fed a beef-protein diet developed the most severe intestinal inflammation. In contrast,\u00a0those consuming pea protein\u00a0experienced only\u00a0mild symptoms.\u00a0<\/p>\n To better understand this link, researchers tested diets\u00a0containing\u00a0different protein sources – including beef,\u00a0eggs, dairy, soy,\u00a0and pea – across multiple\u00a0IBD\u00a0models. In each case, beef protein led to more severe inflammation, while pea protein resulted in the least\u00a0severe inflammation.\u00a0These findings were consistent across models and independent of sex.\u00a0<\/p>\n The study suggests that protein\u00a0source plays\u00a0a key role in shaping gut health.\u00a0Differences in inflammation appear to be driven by how gut microbes interact with the intestinal barrier and bile acids – processes that can either promote or reduce inflammation.\u00a0<\/p>\n These findings highlight the potential for\u00a0diet,\u00a0particularly choices\u00a0centered on\u00a0protein\u00a0source,\u00a0to help manage IBD.\u00a0They may also inform future dietary guidance aimed at reducing disease risk and severity.<\/p>\n Source:<\/p>\n American Gastroenterological Association<\/a><\/p>\n Journal reference:<\/p>\n
