Ulcerative colitis (UC) is a chronic, inflammatory disease of the colon and rectum. It’s one of two main inflammatory bowel diseases, the other being Crohn’s disease.
When a person has UC, sores called ulcers develop inside the colon.
Whole grain breads, cereals, and pastas
Foods that contain a lot of fiber tend to be difficult for people with UC to digest. Whole grain flour is high in fiber because it hasn’t had the germ or bran removed.
You should avoid eating food made from any whole grain flour, such as:
breads
cereals
pastas
noodles
macaroni
During flare-ups, choose white breads and pastas made from enriched white flour, unless you have a gluten intolerance. Flour is “enriched” when nutrients lost during the germ and bran removal process are replaced. Cereals like puffed rice, corn flakes, oats, and cream of wheat are also lower in fiber.
Brown rice and other whole grain starches
Avoid the following whole grain foods:
brown rice
quinoa
buckwheat
oats
wild rice
