> Humans have no tradition of eating them

Bugs are very common food in Asian, African and South American cultures.

Edit: I also remember seeing some ant stuff in Mexico. And I’ve read about indigenous cultures in Australia and North America also having insects as part of their food. I’m sure if I look for it, I’ll find something on European cultures as well. Modern food is just a representation of food that got commercialized, but in reality human diet used to be much more varied than we are used to seeing now.
