What is the function of dietary fiber?

Dietary fiber plays a crucial role in promoting digestive health and regulating blood sugar levels, which is why the chosen answer is correct.

Fiber is classified into two main types: soluble and insoluble. Soluble fiber dissolves in water, forming a gel-like substance in the digestive tract, which can help to slow down the absorption of sugar into the bloodstream. This effect aids in regulating blood sugar levels, making it beneficial for individuals with diabetes or those looking to maintain steady energy levels. Additionally, soluble fiber can help lower cholesterol levels, further contributing to heart health.

Insoluble fiber, on the other hand, adds bulk to the stool and aids in moving food through the digestive system, preventing constipation and promoting regularity. This type of fiber is essential for maintaining a healthy gut, as it supports the growth of beneficial gut bacteria.

In summary, dietary fiber's varied benefits regarding digestion and blood sugar regulation highlight its importance in a balanced diet, making it indispensable for overall health.
