Few things are more uncomfortable than realizing your lunch is giving you a bad case of gas. But if this comes as any comfort, the amount of gas most of us experience is normal and to be expected. "Everyone has gas in their colon, and everyone passes gas every day," says Jennifer Katz, M.D., a gastroenterologist at Montefiore Medical Center. "Most people who complain about excess gas don't necessarily have more than everyone else. They're more sensitive to it."

But, depending on the foods you eat and whether you suffer from certain medical conditions, you may find yourself on the higher end of the spectrum and letting one loose more often. Here's how your digestive process works and a list of 10 foods that give you the worst gas — plus tips to enjoy your favorites without cutting them out of your diet.
