What are the constituent elements that make up a bowel movement and why is our body unable to use so much of the food that we put into it?

Seems like a fairly inefficient system tbqh – is it because we’re eating the wrong stuff? or is it because living organisms create a fixed amount of waste no matter what? Poop is weird. I’d like to understand it better.

Poop is made of many things, mostly water. Like nearly every process in the human body, it needs water to keep things moving along properly. A good portion of the dry weight of poop is actually bacteria. Your intestines are full of trillions of bacteria, and a bunch of them get bound up in the stuff that moves through them. The rest of it is mostly fiber, which our bodies lack the enzymes to break down. Poop also contains cellular debris from your body’s normal processes of maintenance and upkeep.
