People suffering from diverticular disease should avoid eating high-fiber foods for a period of time in order to give the digestive system a chance to rest, according to Mayo Clinic. A doctor may treat a case of acute diverticulitis or diverticulosis with a liquid diet to start, including broth, gelatin, water, coffee and fruit juice with the pulp removed. Soft foods that are low in fiber are added back slowly.
A diverticular diet can't prevent or treat the condition, but rather it eases symptoms that cause discomfort, states Mayo Clinic. In mild cases antibiotics may be prescribed. As symptoms ease, a doctor makes recommendations about foods such as canned or cooked fruits and vegetables, eggs, refined white bread, noodles, and low-fiber cereals. Dairy products such as milk, cheese and yogurt may be reintroduced as well. Most diverticular patients start feeling better within a few days of proper diet and medications, and high-fiber foods can be added back to a normal diet plan.
Experts believe that low-fiber diets cause diverticular disease, according to WebMD. Fiber is essential to a healthy diet as it helps to soften stool, allowing it to pass through the colon and reducing pressure in the digestive tract. Individuals should strive for 25 to 35 grams of fiber per day by eating foods such as beans, whole grains, fresh fruits and vegetables.
