Abstract

Purpose of review

To assess the role of dietary pattern on the occurrence of colonic diverticulosis, diverticular disease and acute diverticulitis.

Recent findings

High-fiber diet does not prevent diverticulosis occurrence, and results about prevention/treatment of diverticular disease and acute diverticulitis are still conflicting.

Recent findings

No association was seen between nut, corn or popcorn consumption and occurrence of diverticulosis, diverticular disease and acute diverticulitis.

Recent findings

It seems to be a mild association between high alcohol intake and diverticulosis occurrence, whereas alcohol dependence seems to show lower risk of in-hospital mortality due to acute diverticulitis.

Recent findings

Higher red-meat consumption shows mild increased risk of acute diverticulitis, especially when consumed as unprocessed red meat (defined as consumption of ‘beef or lamb as main dish’, ‘pork as main dish’, ‘hamburger’ and ‘beef, pork or lamb as a sandwich or mixed dish’); higher consumption of poultry (viz. white meat) was not associated with risk of acute diverticulitis.

Recent findings

Finally, higher fish intake was associated with reduced risk of diverticulitis in age-adjusted model, but not after further adjustment for other potential confounders.

Summary

Current literature data about the role of dietary pattern on the occurrence of colonic diverticulosis, diverticular disease and acute diverticulitis are still too conflicting.
