"Manbeef is an essential part of a nutritious low-carb diet."

Actually the accepted descriptive phrase used by Polynesians who consumed human flesh was "long pig". Omnivores such as us and swine apparently taste similar. Maybe we could get this confirmed by that German cannibal who was recently acquitted of murder after dining on his fellow man.

Everybody here needs to read "Farnham's Freehold", a Robert Heinlein novel, about a Libertarian (well, mostly, he's more balanced) who's family, in a 1960's style bomb shelter, get blasted into a far future where the Muslims won. (Or were at least the ones who emerged into power after East/West nuked a chunk of the planet.) Hugh (ha!) Farnham gets to be the Daniel-esque adviser to a younger prince of the Empire. Alcohol is punishable by death, but "Hapiness" (hash) is an entitlement to keep the slaves in line. Non-muslims are slaves...or worse...as late in the book the hero discovers exactly why pork, which the Koran forbids, seems to be a mainstay in the Royal House...(long pork, that is, son.) If you want to see how a planetwide Muslim empire would run, go find a copy of this book if you can...it his horribly politically incorrect for these times.

Most to all of the more common ET's do not have digestive systems.

Supposedly beef and evidently even human body parts are mixed in a slurry, paste and that is applied to the skin for nutrition. Strange.

But I do believe that the Grey's do not have a digestive system. Not sure what to think beyond that.
