Foods to Avoid With Ulcerative Colitis

Updated February 21, 2017

Ulcerative colitis is a painful condition in which the lining of the colon and sometimes rectum becomes severely inflamed. People who suffer from this inflammatory bowel disease experience cramping, abdominal pain and diarrhoea. Due to the diarrhoea and damage done to the colon, people who suffer from ulcerative colitis are at risk for malnutrition because nutrients may not absorb into the body properly. Avoiding certain foods can promote healing and may reduce the severity of flare-ups.

Common Irritants

Caffeine, alcohol and carbonated beverages are common irritants for a large number of gastrointestinal issues, including colitis. Avoiding these types of drinks may save you some pain.

Raw Produce

Some people who suffer from this inflammatory bowel disorder have trouble digesting raw fruits and vegetables, especially crisp varieties like apples. Baking or otherwise cooking produce may aid in digestion and prevent gas.


Dairy foods like cheese, milk and yoghurt can increase diarrhoea and stomach pain during a flare-up. Try reducing or eliminating altogether dairy foods and monitor how you feel.

Low-Fiber Foods

People with ulcerative colitis often show more symptoms when they consume large amounts of fibre. This is one instance in which a high-fibre diet is not recommended.

Spicy Foods

Spicy foods can heighten the discomfort you feel during a colitis attack and can contribute to diarrhoea as well. Eat a bland diet, avoiding tomato-based products such as sauces and salsas.
