• Beans, nuts, wholegrains etc. are also good sources of fiber.

• Cellulose is a polysaccharide abundantly found on earth. Human body cannot digest cellulose because human digestive system does not release enzyme (cellulases) that digest the compact fibrous structure of cellulose, whereas starch can be digested by humans.

• On the other hand, herbivores and insects like termites can digest cellulose though they do not produce the particular enzyme by hire it from other sources to function.
