Which carbohydrate serves as a source of dietary fiber?

Cellulose serves as a source of dietary fiber because it is a complex carbohydrate that forms the structural component of plant cell walls. Unlike simple sugars or other carbohydrates that are easily digested and absorbed in the small intestine, cellulose is not broken down by human digestive enzymes. Instead, it passes through the gastrointestinal tract largely intact and contributes to dietary fiber intake, aiding in the maintenance of healthy digestive function by promoting regular bowel movements and helping to prevent constipation.

In addition to supporting digestive health, dietary fiber from cellulose can have beneficial effects on overall health, including helping to regulate blood sugar levels and reducing the risk of chronic diseases. It is found in high amounts in fruits, vegetables, whole grains, and legumes, which are important components of a balanced diet.
