How does the soluble fiber component within blackberries contribute uniquely to managing post-meal glucose levels?

By dissolving in water to form a gel-like substance that slows the rate at which carbohydrates are absorbed into the bloodstream

Blackberries contain both soluble and insoluble dietary fiber, each serving distinct digestive roles. While insoluble fiber adds bulk and aids in regularity, soluble fiber performs a critical function related to blood sugar management. Soluble fiber absorbs water within the digestive tract and transforms into a thick, gel-like substance. This gel matrix physically impedes the rate at which carbohydrates from the meal are broken down and subsequently absorbed into the bloodstream. This slowed absorption process is key to preventing the sharp, undesirable spikes in glucose levels that typically occur immediately following the consumption of high-carbohydrate foods.
