Individual triggers for IBS can be different, so you may find that some of the typical trigger foods are fine for you to consume, while others irritate your IBS.
Cut down on dairy. Yes, dairy can be a big trigger for IBS symptoms. Skip the milk, cottage cheese, and ice cream, and go for hard cheeses over soft ones, which tend to trigger symptoms because they are higher in lactose.
Try eliminating foods that are high in fructose. Some examples are apples, pears, and dried fruits. Instead, stick to fruits such as bananas, cantaloupe, strawberries, and blueberries.
Cruciferous veggies, such as broccoli, cauliflower, and Brussels sprouts can trigger IBS symptoms. Cut those out in favor of carrots, sweet potatoes, green beans, eggplant, and zucchini.
Limit consumption of beans and legumes, and instead get your fiber from things such as oat bran, fruits, and veggies.
Some IBS sufferers find that following a low FODMAP diet (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) is helpful. This diet cuts out specific types of carbohydrates that can be difficult to digest. A low FODMAP diet would cut way down on or eliminate all of the potential trigger foods listed above, plus wheat, rye, sugar, and polyols sweeteners, including honey, high-fructose corn syrup, and agave.
