Well they actually can eat human food and they dont't need to poo or pee to flush away the food. The venom in their body will take place in burning the food. But human food cannot give them any nutrition, and blood can. No matter how hard or how many times they try to eat their food, they can never get any nutrition except by drinking blood of course
