Inulin Overview

Inulin is a soluble fiber naturally found in plants such as chicory root. It is classified as a carbohydrate but is not digested into glucose, resulting in very low or zero net carbs. Inulin is commonly used in low-carb and diabetic-friendly foods as a fiber booster and mild sweetener.
