Humans cannot digest cellulose due to the lack of the enzyme cellulase, which is necessary to break down this complex carbohydrate found in plant cell walls. However, cellulose is important in our diet as dietary fiber, which aids in digestion and helps maintain a healthy gut environment. While we can't absorb its nutrients, fiber is essential for boosting digestion, preventing constipation, and may aid in weight management. Incorporating whole grains, vegetables, and fruits into your diet can increase your fiber intake.
