Never Eat These Foods With Ulcerative Colitis And Crohn’s Disease

whole grain breads, cereals, and pastas: Foods that contain a lot of fiber tend to be difficult for people with Ulcerative Colitis And Crohn’s Disease 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

These grains still have the fibrous endosperm, germ, and bran that can irritate Ulcerative Colitis And Crohn’s Disease  may trigger a flare-up.

Avoid these other whole grains:

  • plain barley
  • millet
  • wheat-berries
  • bulgur wheat
  • spelt

A better option for those with Ulcerative Colitis And Crohn’s Disease is well-cooked white rice.


Nuts, including those cooked into other foods or made into flours, should be on your do-not-eat list if you have been prescribed a low fiber diet for Ulcerative Colitis And Crohn’s Disease. The fiber in nuts can be very hard to digest.

It’s best to avoid the following nuts:

  • walnuts
  • hazelnuts
  • pecans
  • cashews
  • almonds
  • macadamia nuts
  • peanuts
  • pistachios

Like nuts, seeds can also aggravate symptoms. Seeds are a type of insoluble fiber, which can cause bloating, diarrhea, gas, and other irritating side effects.

Some seeds to avoid include:

  • sesame seeds
  • flax seeds
  • millet
  • pine nuts
  • sunflower seeds
  • pumpkin seeds
  • wild rice

Legumes, including beans, lentils, and peas, are high-fiber, high-protein foods. Because of the indigestible sugars in beans, they’re also notorious for causing gas. If you are experiencing a Ulcerative Colitis And Crohn’s Disease flare-up, you’ll want to pass on the following:

  • all beans, including chickpeas
  • adzuki beans
  • soy nuts, including soybeans and edamame
Fibrous fruits

While they are healthy for you, most fruits contain a lot of fiber. Fruits belong on the list of foods to avoid if they are:

  • raw
  • dried
  • have seeds that can’t be removed (like most berries)

You can eat fruit that’s been peeled and if the flesh has been cooked until very soft, such as applesauce. You can also eat canned fruits, but choose the type packed in water or in their own juice to avoid excess sugar. Most fruit juices are fine to drink, but only with the pulp removed. Skip prune juice since it’s very high in fiber.

Fibrous vegetables

Like fruits, vegetables are also full of fiber. Include them in your diet only if they are:

  • skinned or peeled
  • have no seeds
  • are cooked until soft

Avoid all raw or undercooked vegetables, including corn. It’s fine to consume canned vegetables and potatoes, as long as the skin has been discarded. Try pureed vegetable soups for an easy way to digest vegetables. Vegetables provide many important nutrients and it’s important to incorporate them in your diet.

Sulfate and sulfides

Sulfate is a required nutrient in the human diet that assists in many body processes, however, it can also feed certain bacteria that create H2S toxic gas in the Ulcerative Colitis And Crohn’s Disease patient.

Dairy products

A common food intolerance among those with Ulcerative Colitis And Crohn’s Disease is dairy. If you suspect dairy may be a symptom trigger for you, remove all types of dairy including butter, milk, yogurt, and cheese for at least four weeks.

Gluten-containing foods

A food intolerance that is becoming more common among those who suffer from digestive symptoms is gluten.
