What Foods to Avoid with Ibs

There are five main symptoms associated with irritable bowel syndrome (IBS), and almost all of them can be triggered by eating the wrong foods. Here is a list of foods that can trigger or acerbate some of the IBS symptoms. Use this handy guide to help you manage your condition.


Refined foods like cereals, chips, and cookies

High-protein diets

Dehydrating drinks like coffee and alcohol (especially red wine)



The best way to alleviate constipation is to eat more fiber, at least 15 grams per day. You may experience more gas and bloating when you increase your fiber intake, but that should wear off after a couple of weeks. Drinking more water and exercising on a regular basis can also get things moving.


Products containing caffeine like chocolate, tea, and coffee

Greasy, high-fat foods like pizza and sausage

Dairy products, particularly if you are lactose intolerant

If you are gluten intolerant, then wheat, rye, and barley will upset your intestines

Foods high in sugar

Artificial fats like Olestra

Excessive amounts of fiber

Fried foods

Strangely enough, eating more fiber will also alleviate diarrhea. Fiber adds bulk to bowel movements and prevents colon spasms. Eating smaller meals reduces the stress on the gastrointestinal system. You should also avoid gas-producing foods because they can worsen diarrhea.


Artificial sweeteners

Sugar-free products like gum and ice cream

Diet sodas containing artificial sweeteners

Avoid overeating, and eat slowly. Don’t consume foods that only add air to the stomach like sodas. Bloating is commonly caused by constipation, so treating that condition will often also alleviate bloating.


Vegetables: beans, cabbage, broccoli, Brussels sprouts, cauliflower, garlic, leeks, onions

Fruits: raisins, bananas, pears, peaches, apricots, melons


Artificial sweeteners

Sugar-free products like gum and ice cream

Carbonated drinks like sodas

Foods containing high-fructose corn syrup

Like bloating, gas often results from eating too fast which can cause excess air to get into the stomach. Take your time eating and avoid airy foods like carbonated drinks. Smoking can also contribute to gas forming, so you should consider quitting.

You can avoid IBS flare ups by eliminating trigger foods from your diet. If you find you are still suffering from irritable bowel syndrome symptoms, taking medication can help. We found several over-the-counter medications that can alleviate IBS symptoms without the unpleasant side effects associated with many prescription drugs.
