What I learned today (that I wish I could unlearn): pre-Columbian pozole was sometimes prepared with human meat.
What is wrong with that, the Catholics, in particular have been practicing their version of anthropophagy, well a pseudo version at least, for nearly 2,000 years now.
Anthropophagy has existed throughout time and cultures. This article is interesting [stufftheydontwantyoutoknow.com]
I would consider eating the placenta after birth to fall into the category of anthropophagy.
No different that munching on any corpse whatever species.
