The article not only offers the obvious explanation that Mexico is the U.S's next door neighbor and therefore very easily influenced, but also the fact that "during the 1990s Mexico joined NAFTA (North American Free Trade Agreement) and acquired US business practices, and perhaps also other behaviors, such as driving everywhere, living on TV dinners, and embracing fast food outlets."
Yes people. You know the famous fast food chain Taco Bell? If you think that it was founded by a happy Mexican family with Chihuahuas and Frida Kahlo paintings in their living room, think again. Taco Bell was founded by Glen Bell, a former U.S Marine soldier. Yes I know: Mexican people getting fat on fake Mexican food created by the Americans. The irony is not lost here.
The article on Medical News Today also states that Sweden is one of the slimmest countries in the world. Now, I'm not going to say this is due to the Swedish Ultra Healthy Diet (only click on the link if you're a Swede) because being Anorexic in Sweden is kind of like...okay. It's like having blond highlights in your hair. People will see, people will confirm, people will accept.
I don't know. Being a Swedish Latina makes me want to eat a vegan wholewheat taco and be creepily unpredictable. Just saying.
