Environmental toxin exposure and gut health in inflammatory bowel disease

Researchers are investigating whether a naturally occurring toxin called deoxynivalenol (DON)—found in some grains and foods—might be an environmental trigger for inflammatory bowel disease, particularly Crohn's disease. The study will analyze tissue samples from people with Crohn's disease and from people undergoing intestinal surgery for other reasons (like cancer or polyps) to understand how the body processes this toxin and how it affects the gut bacteria and immune system. By comparing these two groups, researchers hope to uncover whether DON exposure plays a role in disease development.

Inflammatory bowel disease develops from a complex combination of genetics, gut bacteria, and environmental factors that scientists still don't fully understand. This study aims to identify whether everyday environmental exposures—specifically this food-related toxin—may be a missing piece of the puzzle, which could eventually lead to new ways to prevent or treat the disease.
