Or you eat a lot of beans, cabbage, cauliflower, Brussels sprouts, or bran – all good-for-you foods that contain fibre, which keeps your digestive system moving, helps regulate blood sugar and cholesterol levels, and keeps your weight in check. The less-than-ideal, somewhat-embarrassing, but can’t-help-it side effect? You fart after eating, which is a perfectly normal and healthy thing to do. (If it makes you feel better, call it flatus – the medical term for fart.) That’s because the stomach and small intestine can’t absorb some of the carbohydrates – sugars, starches and fibre – in foods we eat. Notorious gas producers, like broccoli and beans, are high in a kind of carb called raffinose. “When indigestible sugars like raffinose reach the colon, the bacteria that inhabit that part of our digestive tract feeds on them and produce gas as a byproduct,” explains gastroenterologist Rebekah Gross, MD.
