Cure8 research brief
Environmental exposures from agricultural chemicals may affect the gut microbiome and intestinal inflammation, which could be one factor influencing IBD risk or flares. Understanding these links could point to preventive strategies or new biomarkers in the future.
Patients with IBD, clinicians, environmental and microbiome researchers, and people interested in diet–environment impacts on gut health.
This review summarizes evidence linking agricultural chemicals (pesticides, heavy metals, endocrine-disrupting chemicals, mycotoxins, and fertilizer-related contaminants) to changes in the gut microbiota and processes central to IBD, such as barrier dysfunction, oxidative stress, and immune activation.
Most of the mechanistic data come from in vitro and animal studies showing reduced microbial diversity, loss of beneficial bacteria, impaired short-chain fatty acid production, and activation of pro-inflammatory pathways (e.g., NF-κB, MAPK).
The authors note emerging human studies suggesting associations but emphasize that causality in people is not established. The paper recommends more longitudinal human research, exposome approaches, and integrated multi-omics to identify biomarkers of exposure and guide preventive nutritional and environmental strategies.
Findings are primarily based on laboratory and animal studies; human evidence is emerging but not conclusive. The review calls for longitudinal, exposome-based, and multi-omics human studies to clarify causality and identify actionable biomarkers.

Environmental pollutants are increasingly linked to Crohn's disease risk, especially when exposures occur in early life. Understanding these links may help explain rising IBD rates and guide future prevention research.
FUT2 connects genetics, mucosal sugars, and the gut microbiome — pathways that could help explain why some people with IBD have different microbiomes or disease risk. If validated in trials, FUT2-targeted or...
This review spotlights non-bacterial members of the gut microbiota (viruses and fungi) that may contribute to IBD by altering barrier function, immune responses, and interactions with bacteria. For people with IBD, these...
