The modifying effect of dietary index for gut microbiota on the association between urinary arsenic exposure and bladder cancer risk: a nationwide cohort study

Our findings suggest that a diet promoting a healthier gut microbiota, as indicated by a higher DIGM score, may attenuate the association between urinary arsenic exposure and bladder cancer risk. These results indicate that dietary intervention could be a strategic approach to mitigate urinary arsenic-related cancer risk, highlighting the importance of diet-gut-microbiome interactions in environmental carcinogenesis.
