Have you had food lately? Shit's good.
Obviously there are many causes. But one I've been thinking about a lot lately is the difference in available food quality just since the 70s. In America, the only real country, get fucked fags from everywhere else. I mean, even when I was a kid, the general quality of food was far worse than it is today. The Internet as a tool is a main reason, there's 6 gorillion fried chicken recipes out there at this very second, but I've been thinking about the mainstreaming of more ethnic cuisine as a cause of fatness. As progressively more and more ethnic groups become accepted, more and more food enters into the rotation of the home cook. I've been alive long enough to have witnessed the progression of specifically Mexican and Chinese food. Indian and Thai food are travelling this same exact path right now, and Arab and African look to be next up. There was a time, as recently as the 90s, where there was almost nothing from either Mexican or Chinese cuisines in regular grocery stores, especially not premade, frozen, or prepackaged. Now? Your store is guaranteed to have at least half an aisle dedicated to Mexican foods, and another half to the pan-Asian without counting all the shit in the frozen aisle, or at the hot food bar, or the fresh stuff in the grocery areas like poblanos, jicama, jalapenos, etc. Why? It may have a small bit to do with the ethnic groups in your area, but its primarily because everybody eats Mexican food all the time now, and specifically, everybody eats only the very unhealthiest kinds of Mexican food. And that goes double for Chinese food. Shit, I'll bet you can barely find a way to order out Chinese food without it being more than 2500 calories per person.
Obviously, both of those cuisines, and indeed all cuisines except British have normal, healthy meals that normal people eat and don't weigh a million pounds. But they're almost all the same. Rice, beans, veggies, a bit of grilled meat. That is literally the """""secret""""" to healthy eating across the globe. But nobody wants that shit. Give me burritos the size of a newborn, give me orange chicken by the pound, give me some kind of creamy fat, wrapped in a carb, and deep fried, and dipped in a sauce loaded with all the sugar and/or butter you have yeaaaaah fuck yeah food is the best
