I've spent 5 weeks all over Europe now and I gotta say most of your average daily diets are awful, at least from the places I see as a traveler. The irony is that they eat like shit and stay skinny (dat walking culture though).
It's not fair that Americans are the fat ones (our food is spiked with HFCS so of course we're all fat no matter what we do).
French people eat so much fucking bread and sweets and chocolate it's absurd. Every hostel and hotel breakfast I've had served included rolls with chocolate chips. Every breakfast cafe sells CAKE AND PIE for breakfast. Fucking crepes man, they're just carbs folded upon Nutella and store bought fruit jam. You guys just munch on sweets until lunch time, when it's time for more bread, and maybe around dinner time you'll eat something green that is not an onion with some wine.
Germans? Pretty much the same. You guys graze on pastries and beer like its oxygen. It's very hard to find something open for breakfast that cells, I don't know, something that isn't sausage or bread. Your biergartens are just an excuse to guzzle liters of beer with fattening foods.
Czechs drink 150L of beer A YEAR. Men drink 500L of beer a year. Yet Prague had less fat people than any of my cities back in Texas.
Spaniards at least have some variety with tapas. The first country I visited where I felt like I had a choice in how I would die from fried foods.
The worst is many restaurants are not open between 3-6 pm.
As far as being a traveller goes, it's actually way easier for me to eat healthy in America. Not only are there tons of 24 hour food options available, most sell several different types of food at once. And different food groups. Not just sausage and cheese and bread and sauerkraut. I can get a salad for less than 8 euro in America.
That, and the fact that water is not a free natural resource in your socialist haven (seriously, why do you care so much about free access to basic human needs but you nickle and dime people to use the toilet and charge more for water than beer) means that I am encourage to order beer, tea or soda almost every time I go out instead of water (which is usually more expensive because it's fancy tiny bottled stuff).
I have a newfound appreciation for my food options in America. Yeah our cheese and chocolate sucks, but I feel like I can find healthy options more easily.
Edit: yes I am being hyperbolic and generalizing. Don't take this too seriously. After discussing in this thread it dawned on me that maybe Europeans don't eat the same at restaurants as they do at home (which is different than America, I think, where we basically eat the same kinds of food at both, we just go out to eat for either convenience or higher quality). So yeah, maybe it's not the average daily diet. But it's what I frequently observed locals eating.
