Why do we get sweetcorn in our poop instead of fully digested?

Sweet corn may appear undigested in stool primarily because of its outer shell made of cellulose, which humans cannot break down. While the starchy interior is digested effectively, the tough outer layer often survives the digestive process and exits the body intact^[1][6].

Additionally, factors like not chewing the corn well or consuming it too quickly can result in undigested pieces appearing in stool. A high fiber diet, including sweet corn, can also lead to some food passing through the digestive system without complete breakdown^[2][5].
