People suffering from diverticulitis were told up until recently to avoid foods that are difficult to digest, including seeds, popcorn, corn and nuts, according to WebMD, but those recommendations are no longer used and there are no restrictions on dietary intake for diverticulitis, as of 2015. The general recommendation for diet for diverticulitis patients is a diet high in fiber, while a liquid diet may be recommended for initial symptom treatment.
The diet for diverticulitis when symptoms are being experienced may include water, broth, ice pops and fruit juices, with patients advised to slowly return to a regular diet. Low-fiber foods may be recommended at first during treatment, notes WebMD. These foods include meat, poultry, fish, white bread, dairy products and eggs. Eventually, high-fiber foods are reintroduced into the diet.
Some studies suggest that high-fiber foods can be useful in managing the symptoms of diverticulitis, reports WebMD. This includes foods such as beans, vegetables, fresh fruits and whole-grain foods including cereal, pasta and bread. The recommended daily intake is 25 to 35 grams. A fiber supplement, such as Citrucel or Metamucil, may also be recommended for those with diverticulitis, and staying hydrated by drinking sufficient water throughout the day is also a standard recommendation for controlling diverticulitis symptoms.
