Sumary of Are There Certain Foods to Avoid With Ulcerative Colitis?:
- Although high-fiber diets may affect some people with ulcerative colitis during a flare-up, experts generally recommend making sure to get enough fiber during remission.
- One 2017 review of studies found that it may help prolong periods without inflammation—except for in people who have strictures, or a narrowing of the intestine4. “In those patients, we do advise less fiber, because fibers can clump up and cause an obstruction or blockage,” Dr. Hong says.
- Experts commonly recommend a low-FODMAP plan to treat irritable bowel syndrome (IBS), a term that describes a collection of symptoms including abdominal pain, bloating, gas, and diarrhea or constipation.
- However, ulcerative colitis and IBS share some common symptoms5, so your doctor may recommend trying a low-FODMAP diet if you have ulcerative colitis, Dr. Hong says.
- Researchers are studying whether low-FODMAP diets can relieve ulcerative colitis flare-ups, but so far studies have been small.
- A 2016 retrospective study in the journal Inflammatory Bowel Diseases found that a low-FODMAP diet reduced symptoms in 38 ulcerative colitis patients6. More research studying larger numbers of people is necessary to determine whether FODMAPs are a critical factor in ulcerative colitis symptoms.
- However, anecdotally, some people with ulcerative colitis report that curbing their FODMAP intake seems to help their gut symptoms7.Initially, the low-FODMAP diet is very restrictive: The idea is to cut out all FODMAPs before slowly reintroducing some to determine which you can tolerate.
- 3. Cheese, milk, and dairy productsDairy is tricky, Dr. Hong says, because lactose intolerance—or even a full-blown dairy allergy—can sometimes be mistaken for an ulcerative colitis flare-up.
