What is the main role of dietary fiber in the human body?

The main role of dietary fiber in the human body is to improve digestion. Fiber is essential for maintaining a healthy digestive system. It adds bulk to the stool, which helps promote regular bowel movements and prevents constipation. Moreover, fiber can improve gut health by serving as a source of food for beneficial gut bacteria, contributing to a balanced microbiome.

Additionally, fiber can slow down the absorption of sugars, which helps regulate blood sugar levels and can prevent spikes that are typically associated with digestive discomfort. It also has a role in enhancing feelings of fullness, which can aid in weight management. Thus, the multifaceted benefits of dietary fiber are critical for maintaining optimal digestive health and overall well-being.
