Ulcerative Colitis Facts At A Glance

Ulcerative colitis

  • Ulcerative colitis is a chronic inflammatory bowel disease (IBD) that causes inflammation and ulceration of the innermost lining of the colon and rectum (1).

A study conducted on 88,015 Australians found the prevalence rate of ulcerative colitis to be 148 cases per 100,000 population. It was further seen that the prevalence rate in males above 45 years was 83 participants (52%) and the most frequent type of colitis was left-sided colitis (39%).

  • 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 steroidsi  XHuman-made compounds that boost the immune system, reduce inflammation and provide additional strength. 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).
  • According to recent research, a plant-based diet can significantly reduce the risk or relapse in ulcerative colitis patients (7). You can have chicory, garlic, leeks, onion, asparagus, and jerusalem artichokes. These mentioned foods are also considered as prebiotic foods.

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 phytonutrientsi  XNatural chemicals found in plants that are considered useful for human health due to their antioxidant properties. 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

Like 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

The 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. Follow a low FODMAP diet, which includes less sugar intake and will help with intestinal distress.

5. Tea And Coffee

Tea and coffee both contain caffeine, which acts as a stimulant. Stimulantsi  XA substance that makes the mind and body more active or efficient by enhancing or increasing activity of the central nervous system. 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

For 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

Mushroom 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

Prunes 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

Seeds 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

Refined 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

Keep away from a high-fiber diet as they take longer to digest. 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. People with frequent flare-ups should follow an ulcerative colitis flare-up diet.

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

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.

11. Vitamin D

As per one research, Vitamin D can reduce disease activity in UC patients (8). Inculcate vitamin-D-rich foods in your diet such as salmon, swordfish, tuna fish.

The ulcerative colitis diet plays a major role in alleviating this health concern. Consume anti-inflammatory foods for ulcerative colitis that are easy on the colon’s lining and have anti-inflammatory properties to soothe intestinal distress. Remember, foods rich in fiber take time to digest and cause inflammation of the colon, thus exacerbating the condition. Chocolate, sugar, alcohol, smoking, and caffeinated drinks must also be avoided while embracing foods like white rice (low in fiber), fruit juices, eggs, sweet potato, and peeled potato. You can complement this diet with a few yoga poses and a stress-free lifestyle for effective results.
