Passing gas is a sign that your body is functioning normally. When we chew and swallow food, some air naturally gets trapped inside our stomachs. In addition, bacteria naturally living in the intestines emit gas as they break down certain foods. According to the National Institutes of Health, some of this gas is absorbed by the small intestines, where it travels to the lungs to be emitted as breath. The rest, however, finds different methods to exit the body. Flatulence and burping is our body's way of getting rid of this excess air. The average person farts about 10 times a day and burps even more often.

When an individual's gas becomes disruptive to their lives, it can be an indication of gastrointestinal problems. For example, excessive gas is often a sign of Crohn’s disease or even a food intolerance, such as lactose intolerance or a sensitivity to gluten, Women’s Health reported.

Some foods cause more gas than others, depending on how well an individual is able to digest particular compounds, such as carbohydrates, the NIH reported. Click "view slideshow" for a list of some of the most common gas-inducing food and drinks.
