Foods high in fiber, such as vegetables, whole wheat products, pulp-free juices, and tea or coffee without cream, are recommended for those suffering with diverticulitis. Because diverticulitis can include flare-ups, it is important to know what foods to eat during each phase, according the University of California at San Francisco.
When intestines are not inflamed, foods high in fiber are best for a diverticulitis diet. Options include beans, legumes, brown rice, bran, apples, pears, bananas, broccoli, carrots, squash, fish, poultry, eggs, and whole wheat pastas, cereals and bread. These fibrous foods keep the intestinal tract from flaring up, according to Mayo Clinic. Seeds, nuts and popcorn can be part of the diet as long as they are tolerated.
When the intestines become inflamed, diets should avoid any foods that irritate the digestive tract. Options include broth, gelatin and clear juices, according to Mayo Clinic. When moving back to a regular diet, it is best to add yogurt, cheese, low-fiber cereal, tender meat, and pasta slowly to avoid any flare-ups. Water is an essential ingredient to a diverticulitis diet because fiber needs water to help the intestines work smoothly. Water and fiber work together to keep stools soft and prevent inflammation that can lead to a worsened condition.
