Why do zombies crave living flesh? And where does the preference for human meat come from? A zombie will devour any animal it can get its hands on: rats, stray dogs, birds. One meat beats all however: a zombie will stop mid bite if feasting on other species in order to chase after a human. Often their victim can escape with some scratches or chunks missing, these wounds fester and the victim becomes a carrier, destined to eventually turn. The brain seems to hold some sort of allure for the zombie and it prefers to feast on that organ first once it has made a kill. The brain is soft and chewy; the fluids surrounding it give it a tangy kick and piquancy. In short, to a zombie, the brain is the ultimate snack food.
