irritable bowel syndrome

Many people who suffer with Irritable Bowel Syndrome (IBS) and/or Crohn’s disease, find that eating certain foods can leave them feeling bloated, with belly pain or cases of either constipation or diarrhea. 

Irritable bowel syndrome is a common disorder that affects the large intestine (colon). IBS is a chronic condition that you will need to manage long term. And, there are a variety of different factors that can trigger its symptoms, with diet being one of them.

Although there is no specific diet to follow, you can learn ways to manage your irritable bowel syndrome (IBS) by limiting or eliminating foods that may bring on symptoms. Specifically, diarrhea, gas, and bloating. 

While eliminating foods, be sure to consult with someone who specializes in diet to ensure that whatever foods you might be eliminating, that you are replacing with the right nutrients. 

Foods You Want to Avoid to Help Manage Irritable Bowel Syndrome

Many people find that their irritable bowel syndrome symptoms become worse after they eat. Sometimes certain foods, can make symptoms worse.

Foods most commonly listed as causing symptoms include:

  • Onions
  • Hot spices
  • Deep-fried and fried food
  • Coffee (caffeine) 
  • Cream
  • Smoked food

Other types of food that can make symptoms worse include (but not limited to);

  • Lactose. About 1 out of 10 people with IBS also have lactose intolerance. Other people with IBS may have worse symptoms when they eat dairy. 
  • A sugar found in sweet vegetables and fruit, called fructose. In people with IBS, fructose may not be digested as it should. This can cause diarrhea, gas, and bloating.
  • An artificial sweetener called sorbitol. If you have diarrhea, avoid sorbitol. It is found in sugar-free chewing gum, drinks, and other sugar-free sweets.
  • Caffeine. Caffeine can make the intestines move food along more quickly. However, the most common result of caffeine is acid reflux. 

Tips for an Irritable Bowel Syndrome Diet

The following are a few tips from the Intentional Foundation of Functional Gastrointestinal Disorders;


  • Try eating smaller meals. Eat them more often, spread throughout your day. Instead of three (3) meals, try five (5) or six (6) regularly scheduled smaller meals.
  • Slow down; don’t rush through meals. It’s not a race!
  • Avoid meals that over-stimulate your gut, like large meals or high fat foods. 

What is Crohn’s Disease?

Crohn’s disease is a type of inflammatory bowel disease. Crohn’s disease most commonly occurs in the small intestine and the colon. The disease can affect any part of your gastrointestinal (GI) tract, from your mouth to your anus. Similar to that of IBS, however IBS is not a disease but rather a disorder. 

Crohn’s is a disorder of uncertain etiology. It has often been thought of as an autoimmune disease. But research suggests that the chronic inflammation may not be due to the immune system attac,king the body itself, but rather a result of the immune system attacking harmless virus, bacteria or food in the gut causing inflammation that leads to bowel injury.

Crohn’s disease can cause other parts of the body to become inflamed; including the joints, eyes, mouth, and skin. In addition, gallstones and kidney stones may also develop as a result of Crohn’s disease. Sounding a lot more like a ripple effect of symptoms, causing the utmost importance of treating the root of the problem. 

Crohn’s Disease and Your Diet

While foods appear to play no primary role in causing Crohn’s disease, soft, bland foods may cause less discomfort than spicy or high-fiber foods when the disease is active. Now, I might also suggest that since there is some uncertainty to the cause and effect of inflammation and/or auto immune, that similar foods like the ones mentioned above (IBS list) would be beneficial. 

Foods Best to Consumer for IBS and Crohn’s Disease 

The following, is a list of foods recommended when eating to manage symptoms associated with both Irritable Bowel Syndrome and Crohn’s disease. 

  • Plenty of fruit and vegetables
  • Starchy carbohydrates
  • Some protein foods: meat, fish, eggs (for non vegan/vegetarian) and alternatives such as beans and pulses.
  • Limited amounts of foods high in fats and sugars.
  • Limit saturated fat that is found in animal products such as butter, ghee, cheese, meat, cakes, biscuits and pastries. Instead, replace these with unsaturated fats found in vegetable oils such as sunflower, rapeseed and olive oil, avocados, nuts and seeds.
  • Drink plenty of fluid. Such as; water and/or herbal teas.
