A lifelong high-fiber diet for those with asymptomatic diverticular disease may reduce the incidence of diverticulitis and its complications. The 2015 American Gastroenterological Association (AGA) guidelines suggest a fiber-rich diet or fiber supplementation in individuals with a history of acute diverticulitis. [5] However, the guidelines are against routinely advising these patients to avoid the consumption of popcorn and nuts.

According to a large study in the United Kingdom, a high-fiber diet and a vegetarian diet were each significantly associated with a lower risk of diverticular disease-related hospital admission or death. [49]
