Inulin is among the strongest and most widely available compounds with prebiotic effects. Chicory root is a coffee-flavored plant that is incredibly rich in inulin. In fact, chicory root contains so much of the dietary fiber that it is the main source of extraction for commercially produced inulin.
Chicory root is also a perfect source of antioxidant, anticancer, anti-inflammatory, and antiparasitic compounds. However, unlike many of the other inulin-rich foods, chicory root is not a common staple. Some people roast and grind the plant to brew a coffee substitute. Others simply add it to drinks or desserts for a strong, coffee-like flavor.
