FODMAPs are an acronym for a group of foods that are broken down into short chain carbohydrates that ferment and feed the bacteria in the large intestine. In sensitive individuals, FODMAP foods cause gas, bloating, and some other pretty unpleasant digestive disturbances. If you are going into healthcare, you will see people with IBS regularly, since about 1 in 7 people suffer from it at some point in their lives. It would be good to let them know about the Low FODMAP diet. This picture is my interpretation of bacteria feeding and fermenting some high FODMAP foods in the large intestine.
