What is the primary role of hemicellulose in the diet?

Hemicellulose plays a significant role in the diet primarily through its function in providing structure and flexibility within plant cell walls. As a type of polysaccharide, hemicellulose complements cellulose and contributes to the rigidity and strength of plant materials. By integrating with cellulose, it enhances the overall stability and texture of plant-based foods, which is important for digestion and the form of various food products.

While it does not serve as a major energy source like carbohydrates such as starch or sugars, hemicellulose is still a source of dietary fiber, promoting gut health and aiding in digestion. Unlike simple sugars or proteins, which have distinct roles in metabolism and energy generation, hemicellulose's primary contribution lies in its structural attributes.
