To be fair, a lot of this is attributed to your gut microbiome being adapted to the bacteria in your usual diet. Some food may not sit well with you — not necessarily because the food is “bad” but because your system isn’t used to the new bacteria. That’s why locals are fine but tourists aren’t in most cases. On a funny side note, when I was in Nepal we did get some food at a pretty popular restaurant. Everyone had horrific food poisoning later that night, except me since I didn’t touch the cheese!
