To stay healthy and avoid dehydration, people with ulcerative colitis need to eat a balanced diet and drink plenty of fluids. While a specific diet is not believed to cause ulcerative colitis, some individuals with inflammatory bowel disease (IBD) might need to make temporary dietary changes after surgery or to manage symptoms during a flare-up.
Knowing which foods are best when you have ulcerative colitis can be challenging. Research shows that diet can affect the development and course of IBD, as well as the management of symptoms and nutritional status.
Everyone’s experience with UC is different, and it may take some trial and error to figure out which foods work best for you. Doctors know that certain foods can trigger symptoms, but what affects one person may not affect another. By paying attention to what you eat and how your body reacts, you can identify which foods to avoid and find a diet that helps manage your UC symptoms.
Understanding Ulcerative Colitis and Diet
Ulcerative Colitis (UC) is a type of Inflammatory Bowel Disease (IBD) that causes inflammation in the large bowel, affecting the rectum, part of, or the entire colon. While food doesn’t cause UC, certain foods can trigger flare-ups.
It’s important to consider your diet as part of your treatment for ulcerative colitis. Changing what you eat can help keep you nourished and minimise symptoms during flare-ups. The advice about what to eat depends on whether your condition is active (during a flare).
There’s no specific UC diet, but you might need to make short-term changes to support your nutrition and improve your symptoms. It’s essential to understand that while dietary changes can help ease symptoms, they won’t reduce inflammation in your bowel.
Tips to Help Manage Your UC Symptoms Through Food
Here are some tips for handling ulcerative colitis (UC) symptoms through dietary choices. By following these useful suggestions, meal planning can become more manageable:
- Drink plenty of water throughout the day to avoid dehydration, especially when experiencing diarrhoea.
- Prepare meals in advance and keep easy-to-make foods on hand when you’re not ready to cook.
- Stock your kitchen with foods that don’t trigger flare-ups.
- Avoid fried foods and opt for broiling, grilling, steaming, baking, or poaching instead.
- Keep a food journal to track what you eat and any digestive symptoms you experience. This can help you identify personal trigger foods to avoid.
By following these tips, you can better manage your UC symptoms and find a diet that works for you. Remember, everyone’s triggers are different, so it’s essential to find what works best for your body.
What are the Beneficial Foods for Ulcerative Colitis?

While there’s no single diet that works for everyone with UC, eating certain foods can help prolong remission and reduce flare-ups. Since UC affects people differently, it’s essential to find the foods that work best for you. Consider including these anti-inflammatory foods in your diet:
- Fruits like bananas, raspberries, and applesauce
- Cooked vegetables such as squash, carrots, and green beans
- Starchy veggies like potatoes and rice (cooked, cooled, then reheated)
- Fatty fish like salmon, tuna, and mackerel (rich in omega-3 fats)
- Other omega-3 sources like chia seeds, walnut butter, and flaxseed oil
- Leafy greens like spinach and kale (try chopping or blending them into smoothies)
- Probiotic foods like yoghurt, buttermilk, cottage cheese and kefir
Remember, everyone’s triggers are different, so it’s crucial to track how your body reacts to these foods and adjust your colitis diet accordingly.
What are the Worst Foods for Ulcerative Colitis?

Trigger foods can cause unpleasant symptoms, but don’t necessarily harm your body. Everyone’s trigger foods are different, but here is a common list of foods to avoid with ulcerative colitis:
- High-fibre foods like raw kale, Brussels sprouts, and asparagus
- High-lactose foods like cow’s milk and ice cream
- Sugar alcohols and artificial sweeteners like sorbitol and sucralose
- Sugary foods like cookies and pastries
- High-fat foods like butter and fried foods
- Spicy foods like sriracha and chilli powder
- Alcohol and caffeinated drinks
- Sugar-sweetened beverages like soda and sweetened coffee drinks
- Whole grain bread, rice, and pasta
- High-fibre cereals like Bran Flakes
- Certain vegetables like sweetcorn, mushrooms, and broccoli
- Skins of fruits and vegetables like jacket potato skins and cherry skins
- Nuts, seeds, and popcorn
These foods can be hard to digest or irritate your stomach, worsening UC symptoms in females and males. Keeping track of your trigger foods can help you manage your symptoms and find foods that work for you.
Supplements for Ulcerative Colitis

When you have Ulcerative Colitis (UC), getting all your essential vitamins and minerals from a balanced diet is best. However, during flares, you may need to avoid certain nutritious foods. In that case, your doctor might recommend dietary supplements to fill the nutrient gaps. Common supplements for UC patients include:
- Calcium
- Folic acid
- Iron
- Vitamin B12
- Vitamin D
- Vitamins A, E, and K
- Zinc
When choosing a supplement, always read the label carefully to ensure it doesn’t contain ingredients that could trigger a flare, such as lactose or sugar alcohol. This way, you can safely get the nutrients you need to manage your UC.
Final Thoughts
Having ulcerative colitis (UC) means having a long-term illness that can cause inflammation and problems with digestion in your intestines. Some foods might worsen your UC symptoms, so changing what you eat could help you feel better and even reduce your symptoms.
But figuring out the best UC colitis diet isn’t the same for everyone. Your dietary needs and the foods that may worsen your ulcerative colitis (UC) can change over time. Different foods can affect each person in different ways. If you need to change your diet, talking to a healthcare provider is important. They can work with you to create the right plan for you.
Frequently Asked Questions
1. How can ulcerative colitis be treated?
Ulcerative colitis can often be managed with medications. If medication is ineffective, the colon can be surgically removed, which can cure the condition. Viral, bacterial, and parasitic colitis can be treated with appropriate medicines. Pseudomembranous colitis can usually be treated with the right antibiotics.
2. Can ulcerative colitis be cured?
While there is currently no cure for ulcerative colitis, effective treatments such as drug therapy or surgery are widely available. Your doctor can help you find ways to relieve your symptoms and, in some cases, achieve long-term relief.
3. What is the main cause of ulcerative colitis?
The cause of colitis is typically not known. However, it can be caused by infections from viruses or parasites, as well as food poisoning from bacteria.
4. Is colitis very serious?
Colitis can be short-lived and easy to treat, such as when it’s caused by a bacterial infection from food poisoning. However, other types of colitis, known as inflammatory bowel diseases, are more long-lasting and harder to treat. If colitis doesn’t go away, it can cause serious damage to your colon over time.5.
5. Can people with ulcerative colitis live a normal life?
Even when the symptoms are gone, it’s important to keep taking medicine and seeing your doctor regularly. However, people with UC usually live as long as people without UC. Most people with ulcerative colitis lead a full, happy, and productive life.
6. Can ulcerative colitis cure itself?
No, there is currently no cure for ulcerative colitis. However, treatments can help lessen the number of flare-ups and make them less severe. Newer treatments may reduce inflammation.
7. Is ulcerative colitis cancerous?
Over time, the inflammation and constant cell replacement in the colon can lead to a mutation that results in cancer. The more extensive your colitis and the longer you have it, the greater your risk of colorectal cancer.
