Diverticulitis is a disease found in the colon and develops from a condition known as diverticulosis, according to Medline Plus. Diverticulosis involves the formation of pouches known as diverticula on the outside of the colon. Diverticulitis results if one of these diverticula becomes infected and inflamed. Patients with diverticulitis experience fever, nausea and severe abdominal pain. Diverticulitis diet gives the colon time to recover from inflammation.
Clear Liquid Diet
During an active diverticulitis attack, patients are often advised by the doctor to stick to a clear liquid diet for two or three days, according to MayoClinic.com. Clear liquid diet prevents further inflammation of the colon. Examples of clear liquid foods include fruit juice without pulp, broth, clear soda, plain gelatin, tea or coffee without cream and ice pops without bits of fruits or fruit pulp. Continuing clear liquid diet for more than three days can lead to extreme weakness. Patients should transition to a low-fiber diet after three days on clear liquid diet.
Patients should slowly introduce a low-fiber diet as they recover from diverticulitis, according to MayoClinic.com. Low-fiber foods include fruit juice with little or no pulp, eggs, enriched white bread, canned fruits, desserts without seeds or nuts, low-fiber cereals, milk, yogurt or cheese without seeds or nuts, smooth peanut butter, tender meat, white rice, plain pasta and well-cooked vegetables without seeds or skins.
After the acute infection has improved, eating high-fiber foods and using bulk additives such as psyllium may help reduce the risk of diverticulitis, according to MayoClinic.com. High fiber should slowly be increased to avoid excessive gas. High-fiber foods include fruits, vegetables, whole-grain breads such as whole wheat, rye and bran, legumes such as lentils and dried beans, whole-grain cereals, wild rice and brown rice. Patients should ensure that they drink plenty of liquids while on a high-fiber diet. Fiber works by absorbing water and increasing soft and bulky stool in the colon. Patients who fail to drink plenty of fluids may develop constipation.
