*shaking uncontrollably* that's the truth folks!

Don't pack a lunch just yet... It's not safe

Not true. Any mammal that eats its own type of flesh is at an extremely high risk of prion disease. That’s how Mad Cow Disease started: cows being fed cow meat. When humans eat other humans the same thing happens to them. Prion disease: you don’t want it.

Mostly correct

FUN FACT: Human tissue is so toxic from all the crap we eat that it wouldn't pass USDA inspection if it was any other species of animal.

FREE BONUS: Bodies found from people who had drowned out in the ocean show slower rates of decay than they did a century ago because of all the preservatives consumed via the food we eat.

There's a fruit of cycad tree out in some Pacific island somewhere (I forgot which) that the islanders consume, but it requires a complicated multi-step preparation because the food is highly toxic. Boiling... drying... grinding into a flour... boiling again...

Despite this extensive preparation, the people who eat it fairly regularly for years display the same kind of shaking and other neural damage as do those who have absorbed prions from eating human flesh.
