The Worst Foods For IBS


Understanding Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome, or IBS, is a gastrointestinal condition affecting the large intestines. Those suffering from IBS experience painful stomach irritation, cramps, and overall discomfort. Symptoms may include constipation, diarrhea, or both, depending on the type of IBS. The exact cause of IBS is unknown, and there is no specific test for diagnosis. Typically, tests are conducted to rule out other conditions to ensure nothing more serious is affecting you. Since the cause is unknown, there is no definitive treatment for alleviating symptoms. However, reducing stress, monitoring exercise, and adjusting your diet can help manage the symptoms.

Foods to Avoid with IBS

Beans and Legumes

Beans, often touted for their high fiber content, contain indigestible saccharides that can trigger IBS symptoms such as cramping, bloating, and excess gas. Baked beans, lentils, chickpeas, kidney beans, pinto beans, and even peas can exacerbate symptoms. The excess gas these foods cause can lead to a painful digestive process. If you must eat these foods, try mashing them to make them easier to digest. Keeping a food diary can help identify specific triggers.

Fried Foods

Fried foods, especially those from fast food restaurants, are high in fat and can worsen IBS symptoms. Fried chicken, French fries, and burgers may cause bloating, stomach irritation, and diarrhea. Opt for baking or grilling instead. Reducing fatty food intake is crucial for managing IBS, so explore recipes that support a low-fat diet.

Cruciferous Vegetables

While vegetables are generally healthy, those high in fiber, such as broccoli, cabbage, cauliflower, onions, peppers, kale, Brussels sprouts, shallots, leeks, and asparagus, can irritate the digestive system in IBS patients. These vegetables contain raffinose, an indigestible sugar that can cause significant gas and discomfort, especially when eaten raw. Smarter vegetable choices include beets, celery, carrots, sweet potatoes, and squash.

Sugar Substitutes and Sweeteners

Sugar substitutes such as polyol, sorbitol, xylitol, mannitol, and others can cause bloating and irritation in IBS sufferers. These sweeteners, found in sugar-free products, contain sugar alcohol that is difficult to digest. Opt for natural sweeteners like raw sugar, honey, and maple syrup instead.


Pitted Fruits

Fruits high in fructose, such as peaches, plums, apples, pears, mangoes, and cherries, can cause bloating, stomach pain, and irregular bowel movements in IBS patients. Lower-fructose fruits like watermelon, grapes, and berries are better options. Citrus fruits, blueberries, bananas, cantaloupes, strawberries, and kiwis are also good choices, though citrus fruits can sometimes cause digestive issues due to their acidity.


Many IBS sufferers also struggle with lactose intolerance. Dairy products, high in lactose, can cause bloating, discomfort, and diarrhea. Consider lactose-free milk, almond milk, and rice milk as alternatives. Some cheeses are lower in lactose and may be tolerable in small amounts.


Caffeine, found in coffee, tea, and some sodas, can stimulate the intestines and cause diarrhea or runny stool. Coffee specifically contains a GI irritant that can cause intense pain and spasms. Decaffeinated tea, particularly peppermint tea, can be a soothing alternative.

Soda and Carbonated Beverages

Caffeinated soda can irritate the intestines, and regular sodas contain high fructose corn syrup, while diet sodas have artificial sweeteners. Both options can cause gas, cramping, and bloating. Carbonation itself can stimulate the digestive system and cause spasms. Avoid soda and other carbonated beverages to prevent discomfort.


Many IBS sufferers are also gluten intolerant. Foods containing gluten, such as wheat, barley, and rye, can exacerbate symptoms. A gluten-free diet may help reduce symptoms. Gluten-free flour and other alternatives can allow you to enjoy your favorite foods without discomfort.

Spicy Food

Spicy foods can irritate the stomach lining and cause pain and discomfort. They can also lead to heartburn and indigestion. If you enjoy spicy food, limit it to small, occasional amounts.


Corn is difficult to digest and can worsen IBS symptoms due to its high fiber and sugar content. Avoid corn and popcorn, as the salt, fat, and butter in popcorn can also trigger symptoms.

Managing IBS Through Lifestyle and Diet

Lifestyle and dietary changes offer the best relief for IBS. Identify and avoid foods that trigger discomfort. A low FODMAP diet, which limits carb intake, may be recommended. Keeping a food diary can help pinpoint problem foods. Hopefully, this guide has helped you identify foods to avoid to better manage your IBS symptoms.
