Why can’t we digest corn?

It is safe to say that we can partly digest corn. For this, you must understand corn anatomy. Three of the most important parts in corn anatomy are the endosperm, germ, and pericarp. The endosperm contains about 95-98% of the corn starch, the germ is the embryo and the pericarp is the outer husk that protects the corn kernel.

Our body can easily digest the starchy part i.e the endosperm but it is unable to break down the pericarp because it lacks the necessary enzymes and gut bacteria to do the job. The pericarp is made up of cellulose. The enzyme that breaks down the pericarp is called xylanase and is present in herbivores, birds, and other living beings.
