A diet for treating mild or acute cases of diverticulosis often starts with a liquid diet followed by a diet of low-fiber foods, according to Mayo Clinic. The purpose of the diet plan is to give the digestive system a period of rest in order to recover properly.
The first few days of a diverticulosis diet plan may consist of only broth, fruit juice, ice chips or ice pops, gelatin, and coffee or tea without any cream or sugar, according to Mayo Clinic. Patients are also encouraged to drink plenty of water. As the patient begins to feel better, he may start to reintroduce low-fiber foods such as eggs, yogurt, white rice, canned or cooked vegetables, and low-fiber cereals.
High-fiber foods are included in the diet once the patient is feeling better, according to WebMD. Dietary fiber helps to add bulk to stool, reducing pressure in the digestive tract and making it easier to pass through the colon. A diet rich in fiber helps prevent the onset of diverticulitis and controls symptoms. People should strive for 25 to 35 grams of fiber per day by eating foods such as beans, fresh fruits, vegetables, and whole-grain cereals, pastas and breads. Patients who have a difficult time getting enough fiber through food sources should consult their doctor about supplements.
