Ulcerative colitis is painful, recurring, and stressful. If you are suffering from this disease, you should follow a customized diet plan. By avoiding foods that can aggravate the problem and consuming inflammation-fighting foods, you may be able to manage the disease symptoms to a great extent. In this article, you will find out which foods you should eat and avoid, an ulcerative colitis sample diet chart, and how you can heal using natural remedies. But first, let me tell you a few important facts about ulcerative colitis.

Ulcerative Colitis Facts At A Glance

  • Ulcerative colitis is a chronic inflammatory bowel disease (IBD) that causes  inflammation and ulceration of the innermost lining of the colon and rectum (1).
  • About 1.6 million Americans and 2.5 million Europeans are affected by this disease (2).
  • The root cause of this inflammatory disease is not confirmed, but scientists have hypothesized that it may be caused due to the presence of pathogenic bacteria or virus in the gut or an immune system attack on normal gut bacteria (3).
  • The most common symptoms are diarrhea, cramps, rectal bleeding, fever, loss of appetite, joint pain, liver disease, and eye problems.
  • Ulcerative colitis can be diagnosed by X-ray, CT-scan, white blood cell scan, complete blood count, liver function, inflammation markers like C-reactive protein, vitamin B-12 levels, colonoscopy, and antibody blood test (4).
  • It stays lifelong and can flare up from time to time.
  • It can affect anyone at any age and may lead to colon cancer if you have the disease for more than 10 years (5).
  • Medicinal treatments include steroids and medicines that help reduce inflammation, the overreaction of the immune system, and diarrhea.
  • Sometimes, the affected part of the colon is removed to reduce the risk of developing colon cancer (6).

Now that we have got the facts straight, let’s look at which foods you should avoid.

Ulcerative Colitis – Foods To Avoid

1. Broccoli

You are lucky if you are someone who hates eating broccoli. This high-fiber food, loaded with phytonutrients that help improve your health, is a big no-no for you. That’s because broccoli takes longer to digest and can also cause bloating. So, avoid consuming broccoli in any form, i.e., blanched, grilled, sauteed, boiled, or raw.

2. Legumes

Image: ShutterstockLike broccoli, legumes are also rich in fiber. Dietary fiber has many good qualities, but they are certainly not good for you. Fiber-rich foods take longer to digest and add bulk to stools, which might cause irritation to the colon lining, thereby leading to aggravation of the inflammation. Say goodbye to lentils, bean sprouts, kidney beans, lima beans, chickpeas, peas, etc. to help soothe the colon wall lining.

3. Alcohol

If you are suffering from ulcerative colitis, bid adieu to alcohol. Alcohol can highly irritate your colon lining and cause bloating, inflammation, and, in severe cases, rectal bleeding. So, toss your alcohol bottles into the bin and also stay away from drinking at social gatherings.

4. Aerated Drinks

Image: ShutterstockThe sugar loaded and aerated drinks that quench your thirst can cause serious damage to your colon. The colon lining, which is already ulcerated, can get more irritated by the bubbles in the drink. Moreover, the aerated drinks are loaded with sugar and caffeine, which can make you feel bloated.

5. Tea And Coffee

Tea and coffee both contain caffeine, which acts as a stimulant. Stimulants increase the transit time through the colon, thereby chafing the lining of the colon. So, it is best to avoid tea and coffee if you are suffering from ulcerative colitis.

6. Chocolate

Image: ShutterstockFor some of you, it’s bad news. Chocolate contains caffeine and sugar, both of which can highly irritate the innermost lining of the colon. Sugar aggravates diarrhea, and caffeine, as mentioned before, increases the transit time through the colon. Both these ingredients can aggravate the symptoms. So, avoid eating chocolates.

7. Creamy And Greasy Food

Creamy and greasy foods containing loads of mayonnaise, butter, cream cheese, margarine, animal fat, etc. can irritate the inner lining of the colon. This can worsen the ulcers and may cause rectal bleeding. Avoid creamy pasta, macaroni and cheese, and creamy cheese containing foods to pacify your colon.

8. Mushroom And Corn

Image: ShutterstockMushroom and corn are both tough to digest. Most corn kernels are not chewed properly and can cause inflammation. Mushrooms are also not completely digested, so you should steer clear of them.

9. Whole Spices And Herbs

Spices are good but not the whole ones. Do not add whole spices to your food because they will not get digested properly and can scrape the highly sensitive large intestinal walls. If you want to add flavor and aroma to your food, you can chop or grind the herbs and spices and use them. You can also put the spices in a muslin cloth and place it in your food to transfer the aroma.

10. Prunes

Image: ShutterstockPrunes are highly effective for those suffering from constipation since they reduce the transit time through the large intestine. They can be highly dangerous for you because the fast moving foods can scratch the colon walls, leading to inflammation and bleeding. Stay away from fresh and dried prunes and prune juice.

11. Gluten

Gluten is found in oats, wheat, flour, barley, rye, etc. and can worsen the ulcerative colitis in people who are gluten sensitive. So, if you are gluten sensitive, do not consume foods that contain gluten. Be extra careful when you eat out because gluten can be present in sauces and can cause pain and diarrhea.

12. Seeds And Nuts

Image: ShutterstockSeeds and nuts contain healthy fats, but they are also tough to digest. So, do not consume whole seeds and nuts. You can grind them into a fine powder to make a paste to add to your food and get the healthy fats that your body needs.

13. Fatty Meats

If you are suffering from ulcerative colitis, you should strictly avoid consuming fatty meats because they can cause chafing of the colon wall. Choose lean cuts of beef, pork, turkey, and chicken breast to get the protein.

14. Refined Sugar

Image: ShutterstockRefined sugar is also a big no-no for you. It pulls in water and reduces the transit time of the food, thereby making you more prone to diarrhea and scraping of the colon wall. You can substitute refined sugar with jaggery.

15. Cabbage, Celery, And Brussels Sprouts

Avoid eating cabbage, celery, and Brussels sprouts because they are high in fiber and potential colon lining irritants. Instead, have sweet potato, potato, carrots, and squash.

NOTE: Dairy is not mentioned in this list because a few people do not get ulcerative colitis flare-ups while others do. So, check with your doctor to find out if you can consume dairy products.

It may seem like you have run out of options to eat, but that’s not the case. Here is the list of foods that you can eat.

Ulcerative Colitis – Foods To Eat

1. Fruit Juices

Image: ShutterstockYou can drink fruit juices, but make sure you strain them before drinking. Peel the skin and remove the pith before you juice the fruits. Avoid drinking smoothies. Do not drink prune juice and papaya juice.

2. Omega-3 Fatty Acids

Omega-3 fatty acids are great for you as they have anti-inflammatory properties. You can have salmon, mackerel, sardines, flaxseed oil, ground almond, ground flax seeds, ground peanut, and smooth nut paste.

3. Squash

Image: ShutterstockThere are a variety of squashes you can consume – butternut squash, zucchini, summer squash, winter squash, and acorn squash. You can make a stew or blended soup with them for a mouthwatering and filling lunch or dinner.

4. White Rice

White rice has minimal amounts of fiber and is, therefore, easy to digest. Have well cooked white rice to reduce the inflammatory reaction in your colon.

5. Potato And Sweet Potato

6. Eggs

Eggs are a great source of fat-soluble vitamins, minerals, and omega-3-fatty acids. And the best thing about eggs is that they can be tolerated by people suffering from ulcerative colitis. Make scrambled or boiled eggs for a yummy and satisfying breakfast.

7. Avocado

Image: ShutterstockRich in healthy fats, this buttery and nutty fruit is perfect for you. It does not irritate your colon and goes easy on your digestion. Make an avocado smoothie or add avocado to your salad or burritos.

8. Unsweetened Applesauce

Prepare an ulcerative colitis-friendly applesauce by peeling the apples and removing the seeds. Then, boil the apple to make applesauce but do not add refined sugar. You can use a bit of jaggery. Unsweetened applesauce will not cause any flare-ups.

9.Lean Meat

Lean meats like lean cuts of beef, pork, turkey, and chicken breast are your best sources of protein. Protein is essential for your body and should not be avoided. Have lean meats to avoid irritating the walls of your large intestine.

10. Flattened Rice

Image: ShutterstockFlattened rice can be a good substitute for breakfast cereals, quinoa, muesli, and oatmeal. Flattened rice is white rice that is flattened into a flaky form. It can be consumed instantly by adding water, milk, or yogurt. Depending on whether or not you are sensitive to dairy, you can have flattened rice either with dairy or soak it in water for a minute and then add avocado and peeled apples for a filling and soothing breakfast.

These were the list of foods you can consume if you are suffering from ulcerative colitis. Keeping these foods in mind, I have created a sample diet chart for you. Take a look.
