What is the purpose of dietary fiber?

The purpose of dietary fiber is primarily to aid in digestion and prevent constipation. Dietary fiber, found in fruits, vegetables, grains, and legumes, plays a crucial role in the digestive system. It adds bulk to the stool, which helps to facilitate smooth transit through the intestines, making bowel movements easier and more regular. Additionally, certain types of fiber can help manage blood sugar levels and lower cholesterol, further supporting overall digestive health.

Inadequate fiber intake can lead to digestive problems such as constipation, as the body can struggle to eliminate waste effectively without sufficient bulk. This highlights fiber's importance in a well-balanced diet focused on maintaining proper gastrointestinal health.
