Inulin is a plant-derived substance that increases food fiber content and stimulates the growth of beneficial bacteria like Bifidobacteria. It helps control appetite by increasing feelings of fullness. To use inulin, gradually add it to your diet, reducing sugar content in recipes like cookies, brownies, cakes, tarts, and pies. Use chicory root inulin powder instead of sugar in yeast rolls and buns. Experiment with adding more or less inulin to your baked goods, avoiding adding more than 1½ to 2 teaspoons per serving to avoid stomach upset. Inulin can also be added to yogurt, applesauce, pudding, and coffee or tea. It may take trial and error to determine the right amount of inulin for your needs.
