Understanding Inulin

Inulin is a prebiotic fiber found in a variety of plant sources, but it is most commonly extracted from chicory root. Structurally, Inulin is composed mainly of Fuctose units with a terminal glucose, classifying it as a type of dietary fiber known as a Fructan. Unlike other carbohydrates, Inulin is not digested by human enzymes. Instead, it passes through the digestive system to the colon, where it nourishes beneficial gut bacteria. Some key points about Inulin are:

• It is a prebiotic fiber
• It is found in a variety of plant sources, with chicory root being the most common
• It is composed of Fructose units with a terminal glucose
• It is classified as a Fructan
• It is not digested by human enzymes
• It nourishes beneficial gut bacteria in the colon

Historically, Inulin was a significant component of early human diets. Archaeological evidence suggests that ancient populations consumed around 135 grams of prebiotic Inulin-type Fructans daily. Today, modern diets contain far less Inulin, making supplements and Inulin-rich foods more important than ever for maintaining optimal health.

Naturally occurring in about 36,000 plant species, Inulin is found in a variety of inulin foods like:

• whole wheat
• onions
• bananas
• garlic
• asparagus
• Jerusalem artichokes

Chicory root, however, remains the richest commercial source of chicory Inulin. As we explore the health benefits and uses of Inulin, you’ll see why this fiber deserves a place in your daily diet.
