I'm not thin albeit much less fat now than any time since I was a teenager. Once I started traveling more I really picked up on it. I've spent the most time in the Nordic countries and central Europe and unless you go to a massively tourist-focused area the biggest difference I notice is in sugar content. Even Canada has stuff like the Coffee Crisp (candy bar) that is just so much better because you can taste more than the sugar.

There's a serious problem with the mainstream processed food in the US that never even gets talked about. Don't think I'm perfect either, I still drink too much diet soda that's nothing but chemicals. I have cut my sugar intake a ton though, and it's crazy how that's changed my taste on desserts.
