A nurse is teaching a client about managing diverticulosis. Which of the following statements should the nurse make?

Diverticulosis management focuses primarily on dietary modifications to reduce intracolonic pressure and prevent progression to diverticulitis. Limiting daily fat intake to 30% or less is a general healthy dietary guideline that is appropriate to recommend, as a low-fat, high-fiber diet supports overall bowel health. The keyed answer selects this option as correct; however, the most evidence-based recommendation for diverticulosis is a high-fiber diet rather than fat restriction alone. Among the available options, limiting fat to 30% is the most defensible correct choice because the other options are clearly wrong. Decreasing cellulose-containing foods is the opposite of correct advice; cellulose is a type of insoluble fiber that adds bulk to stool and reduces straining. Limiting fiber intake to 20 grams daily is incorrect; current guidelines recommend 25 to 35 grams of dietary fiber per day for diverticulosis management, as higher fiber reduces intraluminal pressure. Taking stimulating laxatives as needed is incorrect and potentially harmful; stimulant laxatives can increase colonic contractions and intraluminal pressure, which may worsen diverticular disease. Therefore, limiting fat to 30% or less is the best available answer from the given options.
