What is a common benefit of insoluble fibers?

Insoluble fibers play a significant role in digestive health, and one of their most important benefits is their ability to stabilize blood glucose levels. This type of fiber does not dissolve in water and adds bulk to the stool, which helps to promote regular bowel movements and prevent constipation. By facilitating a healthy digestive process, insoluble fibers can slow down the absorption of sugar, leading to more stable blood glucose levels. This is particularly beneficial for individuals managing diabetes, as it helps to prevent spikes in blood sugar after meals.

The other options do not accurately reflect the primary functions of insoluble fibers. For instance, increasing cholesterol levels is typically associated with soluble fibers, which can help lower cholesterol by binding to bile acids. Enhancing the flavor of food is not a characteristic of dietary fiber, as fibers are mainly tasteless. Additionally, while fibers contribute to the feeling of fullness and overall dietary satisfaction, they are not used for energy storage. Instead, they pass through the digestive system largely undigested, serving more to support digestive health than as an energy source.
