What characteristic explains why kidney beans result in a gradual, sustained rise in blood glucose?

Answer

Very low glycemic index (GI)

Kidney beans are distinguished by possessing a very low glycemic index (GI), a property indicating that the carbohydrates they supply are digested and absorbed slowly into the systemic circulation. Unlike foods that cause rapid spikes, this slow digestion rate results in a gradual, sustained elevation in blood glucose levels rather than a sharp surge. This metabolic benefit is strongly supported by the combination of the beans' high fiber content and substantial protein levels, both of which act to buffer the overall carbohydrate load entering the bloodstream. This pattern of slow energy release is highly advantageous for maintaining stable metabolic function, particularly supporting the pancreas by minimizing acute demands for insulin production.
