Beans, chickpeas, and other legumes, as well as cabbage, cabbages, peas, and onions, produce a lot of gas during digestion. The reason for this undesirable physiological phenomenon is because these foods contain sugars known as oligosaccharides . These are huge molecules that cannot be absorbed by the small intestine.
In this way, the oligosaccharides pass intact to the large intestine, where they constitute an excellent medium for bacterial fermentation. We must not forget that in our large intestine live at least 200 different colonies of bacteria that form the so-called intestinal flora. These, by breaking down sugars, produce gases that are expelled through the rectum along with volatile chemicals with a foul odor.
