Eat zombies? Much better to drink them.
Interestingly, I once read a short story that involved this very situation—it was set in a Romero-rules style (everyone-who-dies-comes-back-as-a-zombie-if-they-have-an-intact-brain, headshots-kill) world, and one character basically found himself in a survivor’s camp manned by (former) hobos. They’d go out “hunting” for food frequently, but since the zombies had already pretty much killed and eaten all the wildlife, the main character realizes what they were bringing home to eat was zombies.
After some angry assertions that this didn’t make them cannibals, they note that no one’s had any ill-effects from the zombie diet, but there was one odd side effect: anyone who’d been eating the zombies and then died (for whatever reason) didn’t rise as a zombie themselves. Some of the characters (IIRC) were wondering if this was some biological process, or something “spiritual.”
