Only BIRDS can process insect food

Anteaters, aardvarks, opossums, frogs, lizards, echidnas, armadillos, bats, bears, monkeys, chimpanzees, hedgehogs and moles say cease your bullshit.

Humans have eaten insects forever. Even in the soft, privileged west, it is impossible to avoid insects from getting into our food and being eaten. Especially in mass produced processed food. The ancient Greeks and Romans loved to eat cicadas and beetle larvae. Saint John the Baptist lived on locusts and honey when when he lived in the desert, and the early Christians ate locusts, beetles, and grasshoppers.

Every culture has, or still does, eaten insects. US military survival manuals teach troops to survive on bugs and insects.

As for chitin, if you've eaten mushrooms or shrimp, you've probably eaten chitin. It is non-toxic and safe to eat.
