What key digestive component in endive is classified as a prebiotic fiber?

Answer

Inulin

Inulin is highly concentrated in endive and is uniquely classified as a prebiotic fiber. Unlike general dietary fiber which mainly supports regularity, inulin is resistant to digestion by human enzymes. It successfully passes through the upper digestive tract intact until it reaches the large intestine. Once there, inulin acts as a specific food source, actively nourishing and promoting the growth of beneficial gut bacteria. This nourishment of the healthy microbial populations is crucial for maintaining balanced gut flora, which subsequently impacts overall digestive health and potentially immune function.
