What causes undigested food in feces?

Answer 1

By this I assume you mean why you can find pieces of undigested food in feces. Going with this assumption, the reason you find such pieces is because they are indigestible. Bits that are often found in feces include vegetable/fruit skins, seeds, bones, and perhaps even a small coin! Skins often contain a high amount of fiber, which humans cannot digest, and therefore simply pass it out. Seeds are already tough to chew in many cases, and often remain undigested as well. Humans can also not digest bones, and it is not recommended that you eat them because they can puncture the intestine.

Answer 2

Perhaps you mean "undigested" food? Undigested means it wasn't in there very long or it's something thaty doesn't digest well (corn kernels, for example.) With little kids (still indiapers, so you KNOW what the poop looks like) this is fairly common. And many times food coloring isn't well digested, producing fun rainbow shades in the diapers.

Answer 3

Food that contains undigestible components, for example bran or cellulose containing substances e.g. leaves.
