Your pee is entirely blood byproducts (as the kidneys only filter your blood), your poop is mostly blood byproducts, as your digestive system is really good at absorbing almost everything that you eat. So there's also fibre in there along with anything that couldn't be broken down in time as it moved through (corn, nuts, etc…)

Whoa whoa whoa. The kidneys only filter blood?!

If corn and nuts can’t be broken down in time, does that mean that your body does not absorb the full caloric value of the thing?

can no corn be broken down ever? i always wonder why they appear in the toilet. why do ppl eat it then?
​
also, what % of maximum nutrients does the body absorb before it poops? is it like 99%? as a kid i always thought maybe there was an inefficiency and possibly reeating it (obv not a good idea) would help absorb the rest
