Here's the thing... don't give a fuck about UNESCO... but if we're faaaaaaaair... Italian Cuisine and most of European Cuisine wouldn't be what it is today if it wasn't for Mesoamerica's reources. That's one.
Secondly: Mexican Food has been human heritage for years, and most of y'all don't realize that Mexican food hasn't changed that much since prehispanic times.
With the exception of human meat, pork meat, cow meat, we are still cooking and eating pretty much like ancient civilizations did.
Europeans ate like trash, after taking our resources, they're still eating like trash.
Some, are above it, but they be eating like world war planes still be flying over their roofs.
