FODMAP is an acronym for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are different types of short-chained carbohydrates, which are not readily absorbed in the small intestines. Because of their poor absorption (which is completely normal), foods that are high in FODMAPs sit in the digestive system as they await excretion. These foods reach the colon, where the gut bacteria use them for fuel and produce hydrogen gas. Also, since they are carbohydrates, FODMAPs can draw liquid into the lumen of the intestine causing diarrhea. In people with FODMAP sensitivities (i.e. IBS), this can cause digestive tract issues like diarrhea, constipation, gas, cramping, and bloating.

1. What Is the FODMAP Diet?

The FODMAP diet consists of a selection of food items within a diet that aim to reduce the negative effects associated with poorly digested carbohydrates, otherwise called high FODMAP foods. This selection of foods includes food items that are low in the indigestible components, also known as low FODMAP foods. A low FODMAPs diet is indicated for people with specific digestive conditions, who can benefit from a reduction of symptoms caused by high FODMAP foods.
