What is the role of dietary fiber in insulin response?

Dietary fiber plays a crucial role in managing blood glucose levels, making the choice that states it helps stabilize blood glucose levels the most accurate. When consumed, fiber slows down the digestion and absorption of carbohydrates in the body. This slower process prevents sudden spikes in blood sugar levels after meals, which is particularly important for individuals managing diabetes or those concerned about their insulin response.

There are two types of dietary fiber: soluble and insoluble. Soluble fiber, in particular, can help lower blood cholesterol and stabilize blood sugar levels by forming a gel-like substance in the digestive tract. This gel delays gastric emptying and can contribute to a more gradual release of glucose into the bloodstream, thus leading to more stable blood glucose levels over time.

The other choices suggest either negative impacts on blood sugar or a lack of significance, which does not align with the well-established understanding of how dietary fiber contributes positively to insulin response and overall glucose regulation.
