Fructans may not be well tolerated by some subjects and its malabsorption may result in gastrointestinal (GI) symptoms such as heartburn, belching, abdominal pain, diarrhea, gas, and bloating; and this is especially true when higher doses are ingested. Unlike glucose, fructans are not efficiently digested or absorbed by the small intestine. The mechanism for malabsorption is related to the inability to hydrolyze glycosidic linkages in the complex polysaccharide, resulting in the delivery of malabsorbed fructans to the large bowel1. In the colon, the malabsorbed fructans are rapidly fermented, and byproducts of this fermentation include H2, CH4, and other gases that may contribute to bowel symptoms. Furthermore, the small molecular nature of fructans results in an osmotic effect which draws more water into the small intestine and causes bloating and diarrhea.
