What Not to Eat with Diverticulitis: 25 Important Tips

3. Cruciferous Vegetables

During an acute attack, diverticulitis patients should avoid cruciferous vegetables such as cauliflower, broccoli, Brussels sprouts, kale, and cabbage. Cruciferous vegetables, especially when eaten raw, produce gas in the intestines. During an episode of acute diverticulitis, these vegetables may severely tax the digestive system due to their high fiber content. Individuals with diverticulitis should choose alternatives such as cucumbers, celery, zucchini, squash, and peppers. Raw vegetables of any kind should be consumed sparingly to avoid irritating the colon during an active case of diverticulitis. However, high-fiber vegetables are beneficial for colon health and for preventing future diverticulitis attacks when symptoms are not present.
