Yacon syrup is high in prebiotics, such as inulin and fructooligosaccharides (FOS). The concentration of FOS, which are sugars found naturally in many plants, is particularly high in yacon syrup. FOS resist breakdown by enzymes in the human digestive system and reach the colon without being digested. This means that yacon syrup is very low in calories (about 20 calories per tablespoon). FOS also acts as a soluble fiber, which increases stool bulk to help prevent and control constipation.
