[Superman] What if superman were to eat huge quantities of food.

So I assume superman could handle ingesting large quantities of food with ease relative to a human. Say for example if he let someone force-feed him massive amounts of food. So what happens to the food? Would he expand and stretch out like a ball or would he keep his shape and crush the food down into a tiny space inside him? Does superman poop? What would happen as the super dense material left his body, would it suddenly expand? That'd not be a nice bathroom to go into...

What if whilst it was inside him he was exposed to kryptonite? Would his powers being turned off cause the huge amount of food to expand and suddenly cause superman to explode in a mess of body parts and food? What the hell would Lex think had just happened if that occurred?

I wonder if you fed enough food to a constipated superman, would the food get so dense that it creates a black hole in his digestive track?  

**OR**

It's likely that Superman's anatomy can process foods better than we can. It's likely that he utilizes close to 100% of the food as a form of nutrition eliminating the need to poop.
