Cure8 news brief
The study links a common dietary compound (oxalate) to worsened intestinal inflammation in IBD and identifies reduced gut oxalate-transport gene activity and microbiome differences as possible mechanisms—findings that could influence future dietary guidance or microbiome therapies.
Adults with Crohn’s disease or ulcerative colitis; clinicians and dietitians managing IBD; researchers studying diet–microbiome interactions.
Researchers at UNC analyzed gene expression, stool oxalate, dietary patterns (including DNA metabarcoding), and performed mouse and cell experiments.
They observed lower levels of oxalate-transport proteins (SLC26A2 and SLC26A3) in intestinal tissue from people with Crohn’s disease and ulcerative colitis, and higher stool oxalate in some Crohn’s patients despite similar plant-food intake. In mice, an oxalate-enriched diet worsened colitis in susceptible models and reduced survival in one experiment.
The study does not say people with IBD must stop eating plant foods. Investigators note dietary management could focus on lower-oxalate plant choices and restoring oxalate-degrading gut bacteria as potential strategies. Larger human studies are needed before formal dietary guidelines change.
Findings combine human tissue and stool analyses with animal and cell experiments but do not by themselves establish that all people with IBD will worsen on higher-oxalate diets. Larger clinical studies are needed before changing standard dietary recommendations.

The study links a common plant compound (oxalate) to higher stool levels and worse inflammation in IBD, suggesting diet and gut handling of oxalate could affect disease activity and that microbiome-targeted strategies...
Vitamin D deficiency is common in people with IBD and may relate to disease activity, complications, and quality of life; understanding this link could influence monitoring and adjunctive care.
The study suggests a common plant compound (oxalate) may build up in the intestines of people with IBD because transporter proteins are reduced, potentially worsening inflammation. If confirmed, this could influence...
