Why does consuming Jerusalem artichokes not typically cause sharp spikes in blood glucose levels?
Answer
Inulin passes through the stomach and small intestine largely intact.
The low glycemic impact of the Jerusalem artichoke is directly attributable to the nature of its primary carbohydrate, inulin. Since inulin is structurally a fructan and is not broken down into absorbable simple sugars by the time it traverses the stomach and the small intestine, it does not contribute to the rapid influx of glucose into the bloodstream that is characteristic of starchy foods. This allows for stable energy release. Furthermore, this soluble fiber assists in modulating the absorption rate of other carbohydrates consumed concurrently, contributing to overall smoother blood sugar regulation.
