9. Cherries
IBS sufferers are best to steer clear of cherries all together, but too many cherries can cause painful bloating and gas for anyone due to their combination of indigestible fiber, sugar alcohol, and high levels of fructose.
Some people may also get nausea and vomiting from eating cherries due to high concentration of the antioxidant quercetin. If you can tolerate them, cherries are a great source of iron, vitamins, and cancer-preventing antioxidants, but it’s best to stick to just a handful.
