Diverticulitis is an inflammation of small pouches (diverticula) in the intestinal wall. Dietary recommendations differ significantly depending on the phase: during an acute flare, a very gentle, low-fiber or liquid diet is recommended, while in the flare-free interval, a high-fiber diet is considered suitable for preventing new flares. Use the toggle to switch between both phases.
This list is based on a conservative evaluation model. Foods are only listed as 'allowed' if they are frequently described as unproblematic in dietary recommendations. When data is unclear, foods are precautionarily listed as 'forbidden'. This information does not replace medical advice.
With Diverticulitis, 107 foods are currently allowed and 161 foods are not recommended. Check all foods in the interactive tool above.
It strongly depends on the phase. During a flare (acute inflammation), a low-residue diet is recommended: clear broths, white bread, mashed potatoes, white rice, applesauce, and soft-cooked eggs. High-fiber, gas-producing, and raw foods should be avoided.
Outside of an inflammatory phase, a high-fiber diet is actually beneficial: whole-grain bread, legumes, vegetables, fruits, and nuts are considered favorable, as they support bowel transit and may help prevent future flares.
The old recommendation to avoid nuts and seeds is now considered outdated. Current guidelines see no restriction outside of flares. During an acute flare, however, all hard-to-digest foods should be avoided.
During an acute flare, gas-producing vegetables (cabbage, onions, legumes), high-fiber grains, raw fruits, meat, and fatty foods should be avoided. They can irritate the inflammation and delay healing.
During an acute flare, bland diet is recommended for about 7-14 days until the inflammation subsides. Then a gradual diet build-up with increasing fiber intake follows. Duration depends on the severity of inflammation.
After the inflammation subsides, 25-30g of fiber daily is recommended. Increase the amount slowly over several weeks to avoid bloating. Drink sufficient water (at least 1.5-2 liters) alongside.
