What type of fiber promotes efficient elimination and may reduce colon cancer risk?

Soluble Fiber
Insoluble Fiber
Fermentable Fiber
Functional Fiber

The correct answer is: Insoluble Fiber

Insoluble fiber is known for its ability to promote efficient elimination in the digestive system. This type of fiber adds bulk to the stool and aids in moving waste through the intestines, which can help prevent constipation and improve overall digestive health. The presence of insoluble fiber in the diet can encourage regular bowel movements and is thought to play a role in reducing the risk of colon cancer by decreasing the time that waste is in contact with the intestinal walls. While soluble fiber has benefits such as lowering cholesterol and aiding in blood sugar control, it does not have the same effects on promoting elimination as insoluble fiber does. Fermentable fiber is a subtype of soluble fiber that is utilized by gut bacteria, and while it has health benefits, it does not primarily focus on bulk formation for elimination. Functional fiber refers to isolated, non-digestible carbohydrates that have beneficial effects in humans but again does not specifically pertain to the elimination process like insoluble fiber does.
