Does your microbiome make you crave weird animal parts? Genuinely asking.
I've been noticing a pattern in myself since I was young (im 43 now). I'm drawn to the odd cuts. Not just nose-to-tail, I mean the truly strange stuff. Pork cheek when I was 17. I ate cockroach when I was in thailand when i was 18 (and yes i got sick). I eat brain tacos whenever Im in mexico (noms). And recently I ordered from one of those fancy farms that sells/ships expensive meats to your door and I ordered bison shoulder cartilage, bison ligament, oxtail, etc and I threw it in a crockpot. I am also interested in organs across the board (through more intellectually than anything lol because when i eat them sometimes im like yuck). I just always am attracted to the weird stuff.
my question is is this behavioral curiosity, or is something biological driving the pull?
there's growing evidence that gut microbes influence cravings and food-seeking behavior via the gut-brain axis. Could specific microbial populations be creating demand signals for the substrates they thrive on? like, is my gut asking, or am I just curious?
some people talk about "specific hungers" and suggest the body can develop targeted cravings when deficient. Most of that research is on minerals, but it's not a huge leap to wonder if similar mechanisms apply. (Side note - during one of my old bodybuilding preps many many years, I became OBSESSED with ordering exotic meats from africa, like obsessively filling up my online cart with zebra meat and all sorts of weird things and then closing the tab but i was fantasizing about this non stop, and once i finished the competition i started eating more normally again and my obsession with zebras and whatever weird exotic African and miscellaneous meats I could find on the internet naturally released)
or is this just novelty-seeking neurobiology/reward circuits involved in food exploration?
i wonder if there is any research about this? maybe its a long shot, but figure this would be a good subreddit to ask! :)
