Irritable Bowel Syndrome Message Boards

Wheat and some other foods (e.g. artichokes, asparagus, garlic, onions) contain fructans that are indigestible. Inulin which is sold as a soluble fiber supplement is a fructan derived from chicory or Jerusalem artichokes. Heather suggests being very careful of using soluble fiber supplements containing inulin. Fructans are composed of long chains of fructose molecules. The human body does not make enzymes capable of breaking down fructans so they pass through to the colon where the colonic bacteria rapidly ferment them to produce gas and other byproducts. Some individuals with IBS experience an increase in symptoms when they eat foods containing high amounts of fructans such as wheat products. It is possible that Ezekiel bread contains less fructans than regular bread. Individuals who have trouble with fructans don't necessarily have to remove wheat from their diet but rather just reduce the amount they consume.
