What is the key compound in Jerusalem artichoke linked to metabolic benefits and liver support?

Inulin

Inulin is identified as the central component responsible for the observed metabolic advantages of the Jerusalem artichoke. This substance is classified as a prebiotic fiber, meaning it resists digestion in the upper gastrointestinal tract. Once it reaches the large intestine, it acts as a selective fuel source for beneficial gut bacteria. The fermentation process carried out by these bacteria yields vital signaling molecules known as short-chain fatty acids (SCFAs), such as butyrate, propionate, and acetate. These SCFAs then enter the bloodstream, where they play a crucial role in influencing systemic processes like glucose metabolism and the regulation of lipids, thereby indirectly supporting liver function by mitigating fat accumulation markers seen in models of metabolic distress.
