April 1, 2021 Pureed soups are a great way to reap the nutritional benefits of vegetables without irritating your GI tract. Darren Muir/Stocksy For most people, the general advice on nutrition is pretty straightforward: Eat plenty of fruit and vegetables. For people with ulcerative colitis, however, the advice isn’t so simple. The high-fiber content found in nutrient-rich produce can create digestion problems for people with an inflammatory bowel disease (IBD) like ulcerative colitis, especially during a flare (when inflammation is present).
