Question: 1 / 415

Which carbohydrate is recognized for retarding the entry of glucose into the bloodstream?

Complex Carbohydrate

Fiber

Soluble Fiber

The best answer highlights the role of soluble fiber in managing blood glucose levels. Soluble fiber dissolves in water to form a gel-like substance in the digestive tract. This process slows down the digestion and absorption of carbohydrates, which in turn helps to delay the entry of glucose into the bloodstream. By doing this, soluble fiber can help prevent spikes in blood sugar levels, contributing to better overall blood glucose control, which is particularly beneficial for individuals with diabetes or those managing their blood sugar.

While complex carbohydrates also play a role in moderating glucose release due to their more intricate structure compared to simple carbohydrates, it is the soluble fiber specifically that has a more pronounced effect on slowing glucose absorption. Simple carbohydrates, on the other hand, are usually quickly digested and absorbed, leading to rapid increases in blood sugar levels. Fiber, as a broader category, includes both soluble and insoluble types, but it is the soluble fiber that is directly responsible for retarding glucose entry into the bloodstream in this context.
