Which carbohydrate is not digestible and provides fiber in your diet?

The carbohydrate that is not digestible and provides fiber in your diet is cellulose. Cellulose is a type of insoluble fiber found in plant cell walls and contributes to digestive health by promoting regular bowel movements. Since humans lack the enzymes necessary to break it down, it passes through the digestive system intact, supporting gut health and aiding in the prevention of constipation.
