What is the advantage of using plants high in cellulose like sorghum and switchgrass instead of corn?

Because cellulose is a complex polysaccharide which is essential in dietary functions. Since we don't have the enzymes that digest cellulose, it passes through our gut unchanged hence form an important roughage which aids in preventing constipation as well as smooth movements of our intestines.

Ithink its false. hope this : )
