Eating a diet centered around ultra-processed foods may fuel the development of irritable bowel syndrome (IBS).

This study evaluated the relationship between the frequency of ultra-processed food consumption and the chances of developing functional gastrontestinal disorders, such as irritable bowel syndrome (IBS). The eating habits and rate of occurrence of functional gastrointestinal disorders among 33,343 French men and women were ascertained through dietary questionnaires and hospital records.
