Which specific type of fiber found in blackcurrants is noted for its ability to slow the entry of glucose into the bloodstream, promoting stable energy release?

Soluble fiber

Blackcurrants contribute valuable dietary fiber, presenting both soluble and insoluble types. While the insoluble fiber plays the established role of promoting digestive regularity and contributing to satiety (feeling full), the soluble fiber serves a more nuanced function related to metabolic stability. Soluble fiber has the unique characteristic of creating a gel-like substance in the digestive tract which intentionally slows down the rate at which nutrients are absorbed. Critically, this moderates the speed at which glucose, or blood sugar, enters the general circulation, thus facilitating a more steady and sustained energy release throughout the body rather than a sharp spike and subsequent crash.
