However, since bacteria that degrade insoluble dietary fiber, such as cellulose, also exist in humans, as described above, insoluble dietary fiber is slightly degraded by fermentation in the intestinal tract of humans. The caloric content of cellulose was reported to be 4.16 kcal/g. In the human body, cellulose cannot be digested due to a lack of appropriate enzymes to break the beta-acetal linkages. The human body does not have the digestive mechanism to break the monosaccharide bonds of cellulose. Cellulose is a long chain of linked sugar molecules that gives wood remarkable strength. It is the main component of plant cell walls and the basic building block for many textiles and paper. Another way of breaking down the cellulose of a long-cooked vegetable is sauteing. Vegetables high in cellulose and low in water content–such as broccoli, cauliflower, and carrots–should be blanched (boiled quickly until barely tender) before sauteing. Don't blanch softer vegetables like zucchini or eggplant. This medication is used to treat constipation. It increases the bulk in your stool, an effect that helps to cause movement of the intestines. It also works by increasing the water in the stool, making it softer and easier to pass. It is now an EU and FDA-approved food additive and is considered non-toxic to humans. Methylcellulose is a derivative of cellulose that is easier to use for tissue engineering applications as it has better biocompatibility. Although methylcellulose comes from the cellulose of plants and vegetables, its development process isn't entirely natural; it's a synthetically made compound with a complex and refined method. Like regular cellulose, methylcellulose isn't digestible because we lack cellulase, the necessary enzyme.
