Foods with insoluble fibers, sugars, and Lactose can cause unpleasant ulcerative colitis symptoms. A person with ulcerative colitis can work with a doctor to identify which foods are best avoided.

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.

There are sores inside the colon when a person has UC.

Symptoms of the disease include:

Researchers believe UC may result from a number of factors, including dysregulated immune responses, genetic predisposition, genetic predisposition, microbial dysbiosis, epithelial barrier defects, and environmental factors.

A person’s diet and gut bacteria play a role in inflammatory bowel diseases (IBD), but much research into this area is still in its infancy. However, it is clear that a high fiber diet can have significant clinical benefits in people with IBD.

A person should only reduce fiber intake when experiencing acute symptoms like a flare-up or strictures.

During a flare-up of symptoms, a low fiber diet may be helpful in reducing material in the colon, thereby reducing symptoms and helping you recover more quickly.

“People with IBD respond differently to intervention. Some people can tolerate high fiber foods while others can’t.”

It’s best to work with a medical professional, such as a registered dietitian, to develop a diet that works best for managing symptoms and supporting overall health and that not everyone with IBD will do well on the same diet.

During a flare, a healthcare team typically suggests certain dietary modifications, which may include the following:

People with UC find it hard to digest foods that contain a lot of fiber.

Whole grain breads, cereals, and pastas

“Whole grain flour is high in fiber because it hasn’t had the germ or bran removed.”

It is important to avoid eating food made from whole grain flour.

  • breads
  • cereals
  • pastas
  • There are noodles.
  • macaroni

During flare-ups, choosing white breads and pastas made from enriched white flour are better options, unless you have a gluten intolerance.

When the germ and bran are removed, the flour is enriched. Corn flakes, puffed rice, and cream of wheat are cereals that are lower in fiber.

Brown rice and other whole grain starches

Try to avoid eating whole grain foods.

  • brown rice
  • There is a vegetable called quinoa.
  • The food is buckwheat.
  • oats
  • The rice is wild.

The endosperm, germ, and bran are still present in these grains, which can cause irritation to UC.

It is helpful to avoid eating other whole grains.

  • Plain wheat.
  • millet
  • wheat-berries
  • bulgur wheat is a type of wheat.
  • “It’s spelled spelt.”

White rice is a better option for those with UC.


If you have been prescribed a low fiber diet for UC, you should not eat nuts, cooked into other foods or made into flours. The nuts have a hard time being eaten.

  • The pine nuts are nuts.
  • The seeds are from sunflowers
  • Pumpkin seeds.

Dried peas, beans, and lentils

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 UC flare-up, you’ll want to pass on the following:

  • All beans, chickpeas and peas.
  • Adzuki beans are a vegetable.
  • Soy nuts include edamame and soybeans.

Fibrous fruits

Fruits have a lot of fiber, so they are not as healthy as you would think. Fruits are on the list of foods to avoid.

  • It was dried.
  • “Most berries have seeds that can’t be removed.”

If the fruit has been peeled and cooked, you can eat it. You can eat canned fruits, but they should be in their own juice or water to avoid excess sugar.

“The juice with the pulp removed is usually good to drink. It is high in fiber so don’t drink it.”

People with UC have a common food allergy. Lactose is found in most dairy products.

If you suspect dairy may be a symptom for you, you should remove all dairy products for at least 4 weeks.

Work closely with your doctor or dietitian to help you learn how to follow an elimination diet to help identify and remove foods that trigger or worsen your symptoms.

Sugary foods such as candies, high-sugar juices and sugary baked goods can all contribute to UC flares.

A high-sugar diet can also increase a person’s susceptibility to UC flares when they are in periods of remission.

Non-absorbable sugars

The body cannot digest sugar alcohols. Mannitol and sorbitol are nonabsorbable sugars.

Nonabsorbable foods include:

  • There is no sugar-free gum.
  • There are sugar-free drinks.
  • Fruits such as peaches, plums, and pear.

Eating a low fat diet can reduce a person’s risk of developing UC and reduce symptoms in those with the condition.

  • There are coconut and other oils.
  • It is margarine.

It is helpful to limit soft drinks in order to manage your condition.

The Crohn’s and Colitis Foundation states that spicy foods can worsen UC flares. However, research in this area is limited.

In fact, a 2019 review suggests that capsaicin, which is the active component in hot chilies that gives the feeling of spice, can actually reduce intestinal inflammation and IBD symptoms.

People with bicyle symptoms are more likely to have a food allergy to the wheat flour.
