Interesting thread.
Made me laugh.
I cringe at some of the "cuisine items" too, but I know from friends around the globe, they cringe at some of our habits as well!
Cheese, for some!
Go figure!
I have done quite a few survival courses here in the NW of America. Two were very strenuous, and yup, I had to eat grubs and worms.
Imo, it's all mental folks.
It's not much more than getting over the idea that eating sushi is eating "raw" fish....(btw, I love sushi, although many years ago, I didn't).
I've had some interesting items in my diet over the years, including bear, rattlesnake, goat, squirrel, crayfish, et cetera....
I'm still alive! lolol...
And YUP, I still cringe at most bugs!
But to survive? You bet I'd have no problem.
jmo.
