Chicory (Cichorium intybus) is a plant that is widely grown in northwestern Europe. Chicory roots are a rich source of a water-soluble fiber called inulin.

Chicory inulin is not digestible and can be used to replace dietary fat or sugar in some processed and functional foods. Using inulin instead of sugar or fat can result in a lower-calorie food.

Chicory root is also commonly used in the preparation of a bitter coffee substitute in France and Japan. Chicory root coffee is becoming more popular in certain areas of the U.S.
