Does fiber prevent appendicitis and diverticulitis?

Fiber can help reduce the risk of diverticular disease and constipation, but it does not definitively prevent appendicitis or diverticulitis.

While consuming fiber can help keep your digestive system healthy and functioning properly, neither fiber nor diet can prevent appendicitis. Appendicitis is caused by an obstruction or inflammation of the appendix, typically by fecal matter or bacteria. Fiber-rich foods can promote regular bowel movements and alleviate constipation, which may reduce the risk of developing diverticulitis, but the relationship between fiber intake and prevention of diverticulitis is not conclusively established. Consulting with a healthcare professional for personalized dietary recommendations is always advisable.
