    Frequently Asked QuestionsUC Diet & Nutrition

    What diet should I follow if I have ulcerative colitis?

    There’s no such thing as a one-size-fits-all “ulcerative colitis diet.” That said, most experts recommend a plant-based, Mediterranean diet, along with working with a registered dietitian to develop a meal plan that works for you. Your R.D. may also recommend a low-residue diet (one limits high-fiber foods) or a low-FODMAP diet, which involves avoiding foods with certain types of sugars, to help reduce your symptoms.

    What should I eat during an ulcerative colitis flare?

    It’s best to work with your doctor or registered dietitian to come up with a meal plan that tailors to your specific needs when you have active UC. Typically, however, foods prepared simply (e.g. grilled, steamed, or poached), low-fiber foods, lean proteins, and fully cooked, peeled, and seedless fruits and non-cruciferous veggies are well-tolerated.

    What foods should I avoid if I have ulcerative colitis?

    Trigger foods vary from person to person. However, some common foods that may worsen UC symptoms include fatty foods, sugary foods, alcohol and caffeine, cruciferous vegetables, and lactose.

    Can I treat ulcerative colitis with diet alone?

    UC can’t be managed with just diet—but it is often an important piece of the puzzle. You’ll likely use a combination of medical therapies along with diet changes to help manage your UC effectively.
