I eat the joints of bones - further up they tend to splinter and taste more chalky, but the joints are delicious and satisfying once you get past the ick factor. I thought even the cartilage was gross as a kid, but at some point instincts kicked in and my body told me it was a great idea. I knew marrow was nutritious and some people ate it, but I still don’t find it that appealing - joint bones are one of the most satisfying things ever though, I highly recommend gnawing on the end of a chicken wing

Just because of your comment, I grabbed some tree bark to try… Cinnamon sticks. And holy shit, I just wanted to try it out, but I couldn’t stop. It just splinters at first, but once you start grinding the flavor kicks in and it just melts - 10/10, it’d be easy to eat enough to make yourself sick, but I’m going to be trying this again

And FWIW, I’ve never had a cavity. I brush my teeth every morning but otherwise only if I feel I need to. I slightly cracked a tooth once, but my dentist was great and told me to use fluoride toothpaste and hold off on a crown - it’s been a decade and it hasn’t bothered me in years

Trust your body. Yes, gnaw on bones and tree bark - not all of it, your body knows what is edible and what isn’t. If your instincts say “gnaw on this”, and it’s not made of plastic or metal, give it a try… If you take it slowly, what’s the worst that can happen? Probably a tummy ache
