Association between long-term ambient air pollution and incident inflammatory bowel disease across levels of adherence to a plant-based diet: a prospective cohort study in the UK Biobank

If true, the study suggests that long-term air pollution exposure may raise the risk of developing IBD and that greater adherence to a plant-based diet could be linked with a lower pollution-related risk. That may be...
