What is the primary dietary recommendation for patients diagnosed with diverticulosis?

Choice A reason: Increasing dietary fiber is the cornerstone of nutritional management for diverticulosis. Fiber adds bulk to the stool, promotes regular bowel movements, and reduces intraluminal pressure in the colon, which helps prevent the formation and inflammation of diverticula. Choice B reason: Increased sugar intake has no therapeutic benefit in diverticulosis and may contribute to poor overall dietary quality. It does not aid in bowel regulation or reduce diverticular complications. Choice C reason: Protein intake is not directly related to diverticulosis management. While balanced nutrition is important, reducing protein does not affect diverticular disease progression or symptoms. Choice D reason: Adequate water consumption is essential when increasing fiber intake to prevent constipation. Reducing water intake would counteract the benefits of fiber and increase the risk of bowel obstruction.
