Another cause of excessive flatulence is the consumption of large amounts of fruits that are high in soluble fiber, says Everyday Health. People cannot digest fiber, but the bacteria in the digestive tract can break it down. Some fruits contain sorbitol, a type of sugar alcohol that can lead to the production of gas. Fruits with high levels of sorbitol include blackberries, peaches, prunes and pears.

Cherries, lychees and avocado contain low amounts of sorbitol, according to Jillian Michaels. Fruits such as bananas, oranges, strawberries and blueberries do not contain significant amounts of sorbitol or carbohydrates, so they are less likely to produce gas when consumed. Slowly decreasing the intake of dietary fiber can gradually improve gaseous symptoms, but individual responses can vary. Some people are more prone to producing gas from eating high-fiber foods, so it may be necessary to try different types of fiber, claims the International Foundation for Functional Gastrointestinal Disorders.
