Dealing with ulcerative colitis can be tough. But, the right diet can help you ease your symptoms. This article will show you what foods to eat. It aims to help you feel better and improve your health.

Table of Contents

The first step is understanding what causes ulcerative colitis. Things like where you live, what you eat, and your genes play a big part. These factors are tied to this ongoing gut condition.

Unfortunately, there’s no one-size-fits-all diet for everyone with ulcerative colitis. Yet, cutting out foods that bother you can make a big difference. Still, being careful with what you eat might lead to missing out on some nutrients.

Understanding Ulcerative Colitis and Diet

What is Ulcerative Colitis?

Ulcerative colitis is a long-term disease that causes inflammation in the gut. It mainly affects the large intestine and the rectum. This disease makes the lining of the colon swollen and develop sores. Its main symptoms are diarrhea, stomach pain, bleeding from the bottom, and urgent needs to go to the bathroom.

People with ulcerative colitis have periods where the symptoms get very bad (flare-ups). These are followed by times when they feel better or have almost no symptoms (remission).

The Role of Diet in Managing Symptoms

What we eat is key in controlling the disease. Some foods can start off or make symptoms worse during bad times. But some foods can ease the pain and speed up healing when symptoms are less.

Choosing the right food and managing how you eat can help a lot. It can make the condition easier to deal with and improve life quality.

Diet Recommendations During Flare-ups

When you’re in the middle of an ulcerative colitis flare-up, a low residue diet can help. This diet focuses on low fiber, easy-to-digest foods. For example, you can eat bananas, white rice, and cooked vegetables. This helps take the load off your digestive system, giving it time to heal.

Avoiding Trigger Foods

It’s key to stay away from foods that make your ulcerative colitis worse. During a flare-up, steer clear of high-fiber items, processed meats, and dairy. Also, avoid sugar alcohols, acidic fruits, and high-fat foods. A food journal can help you find out what affects you personally. This way, you can choose what to eat more wisely.

Increasing Omega-3 Intake

Getting more omega-3s in your diet might help fight inflammation and reduce symptoms. You can find omega-3s in fatty fish like salmon, mackerel, herring, and sardines. Including these foods in your diet can be good for your ulcerative colitis.

Diet Recommendations for Remission

As your symptoms calm and you move into remission, start adding foods slowly. Begin with clear liquids and soft foods, then move to a wider variety carefully. Watch how your body reacts. Doing this can show you what foods are safe and what could bring back your symptoms.

Reintroducing Foods Gradually

Moving into remission means you need to be careful with what you eat. Start with easy-to-digest foods like broths and soft fruits. Then gradually include more variety to see how your body handles them. This method helps you know exactly which foods might still bother you.

Increasing Fiber Intake

Once you’re in remission, slowly up your fiber by eating more soft-cooked veggies and fruits. You can also add whole-grain starches. This change can make your gut healthier and keep your bowel movements regular. But remember, do it all slowly to make sure your body is okay with these new foods.

Maintaining a Balanced Diet

Being in remission means eating a mix of fruits, veggies, grains, proteins, and dairy. This varied diet gives you the nutrients you need for good health. Always pay attention to how your body feels. Make any changes necessary to keep your digestion working well.

Specific Foods to Eat with Ulcerative Colitis

Low-Fiber Fruits

When managing ulcerative colitis, eat fruits that are low in fiber. Good choices include bananas, honeydew melon, and mango. These fruits go easy on your stomach and are less likely to cause problems.

Non-Cruciferous Vegetables

Stay away from veggies like broccoli and cabbage. Instead, choose non-cruciferous ones. For example, try potatoes, sweet potatoes, cucumbers, and carrots. They’re easier on the digestive system for people with ulcerative colitis.

Refined Grains

Go for refined grains like white pasta and white rice. Also, enjoy oatmeal and certain breads. These are simpler to digest than whole grains. They’re lower in fiber, which your body might handle better.

Omega-3 Rich Foods

Add more omega-3 fatty acids to your diet. Foods like salmon, mackerel, walnuts, and chia seeds can help fight inflammation. Thus, these foods might aid in managing your symptoms.

Lean Proteins

Lean proteins are key for those with ulcerative colitis. Choose fish, chicken, turkey, and eggs. They are not only well-tolerated but also essential for your health.

Foods to Avoid with Ulcerative Colitis

If you have ulcerative colitis (UC), it’s important to watch what you eat. Knowing what foods to avoid can help you manage your symptoms better. This reduces any pain or discomfort you might feel.

High-Fiber Foods

Stay away from high-fiber foods like raw fruits and veggies, nuts, seeds, and whole grains. They can make symptoms worse, especially when your UC flares up.

Processed Meats

Processed meats are also not a good idea. This includes deli meats, bacon, and sausages. They are often high in fat and could increase inflammation.

Dairy Products

If you find that dairy bothers you, it might be wise to cut back. This means reducing or skipping milk, cheese, and ice cream.

Sugar Alcohols

Watch out for sugar alcohols found in sugar-free products. Examples include sorbitol, mannitol, and xylitol. They can upset your stomach.

Acidic Fruits

Fruits like citrus, tomatoes, and other acidic types can be tough on your gut. It’s best to eat them less, especially when you’re not feeling well.

High-Fat Foods

High-fat foods are another group to avoid. This includes fried foods, butter, creams, and processed snacks. They might be hard for your body to handle.

Dietary Approaches for Ulcerative Colitis

When dealing with ulcerative colitis, choosing the right foods can really make a difference. Several diets have been researched and found to help reduce symptoms and even put the disease into remission.


The low FODMAP diet is all about cutting back on certain carbs. These carbs can cause trouble for the gut, leading to issues like bloating and gas. A study from 2020 showed this diet can lower the severity of IBD symptoms and ease gut problems.

Paleo Diet

The paleo diet is focused on eating natural, unprocessed foods. It avoids grains, dairy, and processed items. Some studies have suggested it could lower inflammation and make symptoms better for those with ulcerative colitis.

A 2017 study found that an autoimmune protocol diet, which is like a strict version of the paleo diet, helped 11 of 15 people achieve remission by the sixth week of the study.

Mediterranean Diet

The Mediterranean diet is packed with fish, olive oil, fruits, and veggies. It also includes whole grains. This diet has shown promise in lowering disease activity and helping people with ulcerative colitis go into remission.

Research from 2021 supports the idea that a Mediterranean diet could lower disease activity in IBD, including ulcerative colitis.

Food Preparation and Meal Planning

For those with ulcerative colitis, carefully preparing and planning your meals is key. Being proactive means you’ll have easy-to-digest options, packed with nutrients, especially during flare-ups. These times can make cooking tough, but being prepared helps a lot.

Staying Hydrated

Drinking enough fluids each day is a must. Water, broth, and rehydration solutions are great choices to replace lost fluids from diarrhea and avoid dehydration. This simple step helps reduce some of the discomforts that come with ulcerative colitis.

Meal Prepping

Getting meals ready ahead of time can truly change the game. With a range of easy-to-make meals and snacks at your fingertips, cooking during flare-ups becomes way less stressful. You’ll also be sure you’re eating the right foods to fuel your body.

Easy Meal Ideas

Some meal ideas that are simple to make and easy on the stomach include smoothies, oatmeal, baked potatoes, and grilled chicken or fish. These dishes are gentle on your gut, giving you the nutrients you need during all your ulcerative colitis phases.

Cooking Methods

Choose cooking styles that are kind to your food and your stomach, like boiling, grilling, roasting, steaming, and poaching. These methods lock in nutrients and make meals easier to digest. This is extra important when you’re in the middle of a flare-up.

Following these cooking and meal planning tips each day helps you take control of your ulcerative colitis. It’s a step to feeling better, and improving your life’s quality overall.

Cultural and Traditional Foods

Many folks with ulcerative colitis find it hard to eat their cultural foods. These meals can soothe but also stir up health issues. With some creativity and care, it’s possible to savor your heritage dishes safely.

Adapting Recipes

When some of your favorite foods cause issues, tweak the recipes. Swap out ingredients that bother your stomach. For instance, replace beef with chicken or fish. Cut back on spicy seasonings too.

Portion Control

If you can’t avoid problematic foods completely, enjoy them in small amounts. Watch how your body reacts. Eat less if it doesn’t feel right.

Nutritional Supplements for Ulcerative Colitis

Living with ulcerative colitis may cause you to lack some nutrients. Your doctor might suggest certain supplements to help. These supplements aim to fill nutritional gaps or boost your health.

Start with a standard multivitamin for a good mix of vitamins and minerals. You could also need specific supplements. For example:

  1. Omega-3 fatty acids: Studies show fish oil’s omega-3s can lessen symptoms and lower ulcerative colitis’s chance of coming back.
  2. Calcium: You might need extra calcium to keep your bones strong. Aim for 1,000 to 1,200 milligrams each day.
  3. Iron: Iron supplements could be needed if colon bleeding is causing anemia.
  4. Folate or folic acid: These nutrients can help, especially if you can’t get enough from your diet.

Some research hints that probiotics and aloe vera might help too. But, we need more studies to be sure.

Always talk to your doctor before adding supplements. They can guide you on what’s right for you, considering your health and history.

Medications and Nutritional Side Effects

Some medicines for ulcerative colitis might lead to problems with nutrition. They could make it harder for your body to take in important vitamins and minerals. It’s important to watch your diet closely and work with your doctor to avoid any shortages.

Corticosteroids, a type of drug, can cause the body to break down protein faster. This could mean you need more protein. With these drugs, it’s smart to get plenty of calcium to keep your bones strong. Another medicine, cholestyramine, might make it tough for your body to use vitamins A, D, E, and K. It also hinders the absorption of some important nutrients such as folate, vitamin B-12, calcium, and iron.

Then, there’s sulfasalazine. It can stop your body from soaking up enough folate. If you take it, you might need to add a folate supplement of 1 milligram daily. Keeping an eye on your nutrition levels and fixing any shortfalls with your doctor’s help is key.

The Impact of Surgery on Nutrition

Surgery might be needed for those with bad ulcerative colitis. This could mean removing the colon or changing how the small intestine ends. These operations can change how the body absorbs nutrients, leading to possible shortages.

After surgery, working with a dietitian is key. Malnutrition is a big risk for these patients. Managing nutrition well is crucial for anyone who has had surgery for this condition.

The surgery’s effect on nutrient absorption can differ. This can lead to a lack of important vitamins, minerals, and macronutrients. A tailored nutrition plan, regular checks, and perhaps supplements can make a big difference in the patient’s health and recovery.

A dietitian’s help is important post-surgery. They ensure patients get the right nutrients for good health. This teamwork is essential for those recovering from ulcerative colitis surgery.

Foods to Eat with Ulcerative Colitis

Important foods for those with ulcerative colitis are low-fiber fruits and vegetables without seeds. Also, eat refined grains, omega-3 foods, and lean meats. Remember to stay away from foods that can trigger symptoms. These include high-fiber items, processed meats, and sugary foods. During flare-ups, avoid dairy, acidic fruits, and high-fat choices.

With the right diet and advice from your healthcare team, you can control your ulcerative colitis. A personalized nutrition plan is key to managing this chronic disease.


Managing ulcerative colitis through diet can be tricky and very personal. Knowing how food affects your symptoms is key. Plus, finding the right foods and planning your meals well can be a big step in feeling better.

Talk to your doctors and nutrition experts to make a plan that’s just for you. With their help and the right foods, living well with ulcerative colitis is more than possible.

Keep learning, trying new foods, and talking to your medical team. This kind of open communication is important in figuring out what diet helps you the most. Putting your nutrition first helps you take control and enjoy your life more.
