How Good Is Your Diet for Ulcerative Colitis?

If you have ulcerative colitis (UC), you may not be able to eat everything you want, but your diet shouldn’t be strictly limited either. In fact, when you’re in remission, you should be able to eat most of the same foods as anyone else.
That said, some foods can trigger UC symptoms, particularly in people who are in the midst of a flare, according to the Crohn’s & Colitis Foundation. Even seemingly healthy foods, such as raw vegetables, can bring on painful symptoms, such as diarrhea.
Knowing what you can and can’t eat can take a bit of trial and error. “While one person’s way of eating may work for them, it may not work well for all people with ulcerative colitis,” says David Gardinier, RD, whose specialty is inflammatory bowel disease (IBD) at Cleveland Clinic’s Center for Human Nutrition. Take this quiz to gauge how your food choices are affecting symptoms.
This assessment is part of a series aimed at helping you check in on UC before your next checkup with your doctor. Take more assessments.
