You may be able to tolerate cooked, peeled, and soft vegetables during ulcerative colitis (UC) flare-ups. Cooked carrots, potatoes, and parsnips are examples of vegetables to eat.
Ulcerative colitis (UC) is a chronic type of inflammatory bowel disease (IBD).
Eating certain types of food may trigger symptom flare-ups, while eating others may help your body stay in remission.
Vegetables contain valuable nutrients and micronutrients, but some vegetables may worsen your UC symptoms.
Keep reading to learn more about which vegetables to eat and avoid if you have UC.
The following vegetables are recommended for people who are living with UC.
During a flare
The tendency during a flare-up is to cut down on vegetables to help relieve symptoms. But, while restricting some foods may help reduce symptoms, too much restriction may lead to deficiencies in nutrients
- iron
- folic acid
- magnesium
- vitamin B12
- vitamin D
- zinc
These deficiencies may put you at risk of complications such as nutrient malabsorption, weight loss, osteoporosis, and anemia.
The Crohn’s and Colitis Foundation (CCF) recommends that, during a flare-up, you eat vegetables that are:
- cooked or steamed until they’re soft
- canned
- peeled
- made into vegetable stock, juice, or soup
Cooked vegetables you may be able to eat during a UC flare-up include:
- carrots
- potatoes
- squash
- green beans
- parsnips
- rutabaga
- eggplant
- zucchini
- pumpkin
It’s important to avoid eating the skins of vegetables because they’re typically high in insoluble fiber. This is a type of dietary fiber that is
Raw vegetables are also harder to digest and can result in UC symptoms such as abdominal bloating and gas.

In this study, 71% of participants with IBD reported that diet affected their condition. Most healthcare professionals also reported that diet had a role in IBD.
However, 61% of the participants felt that their doctors didn’t acknowledge the role of diet in their condition. Only 26% of the participants reported receiving dietary advice.
The CCF recommends that you gradually add more vegetables to your diet during remission.

Until there are clear and consistent guidelines for a UC remission diet, it’s best to focus on maintaining a diverse and nutrient-rich diet.
Some vegetables are harder to digest and may irritate your gastrointestinal (GI) tract.

The CCF recommends eating vegetables that have been prepared in the following ways during a UC flare-up:
- Peeled or skinned: Vegetable peels and skins are high in insoluble fiber, which is hard to digest and may trigger UC symptoms.
- Cooked: The fiber in raw vegetables may be hard to break down and may cause symptoms. Grilling, steaming, or boiling vegetables until they’re soft may make them less likely to cause symptoms.
- Canned: Canned vegetables may be softer and easier to digest than raw vegetables. Make sure they’re canned in their own juice or water and have no added sugar.
What vegetables are good for ulcerative colitis?
Non-cruciferous vegetables such as carrots, potatoes, and rutabaga may be good to eat during a UC flare-up. However, avoid raw vegetables, especially their peels. Peeled, steamed, and cooked vegetables are soft and easier to digest.
Can you eat lettuce with ulcerative colitis?
Yes, people with UC generally tolerate lettuce well. But if you experience a symptom flare-up after eating lettuce, it’s best to avoid it from then on.
Are cooked vegetables good for ulcerative colitis?
People experiencing a UC flare-up often best tolerate cooked, grilled, or steamed vegetables. These preparation methods help break down the insoluble fiber, which is hard to digest in raw vegetables.
A balanced diet is important for everyone, but eating nutritious foods is especially critical when you have UC. The condition can affect how well your body absorbs vitamins and minerals.
Some vegetables are more likely to cause UC symptoms than others. The more colorful the vegetables you choose, the more nutrition you’ll get. Try different vegetables and cooking methods to see which ones worsen your symptoms and which ones you can tolerate.
