In Europe you don’t expect your bread to have added sugar, for instance. That tasted disgustingly.
You also don’t normally expect sweeteners in your meat. Those sauces are also disgusting. Good beef meat (and in the USA there’s very good meat), needs only salt and maybe a bit of pepper. Not those weird sugary sauces they put in the USA.
Seriously, for someone from Europe, some food in the USA is just disgusting (and it’s not due the quality of the ingredients, as those are usually very good) but due to the stuff they add on top.
Take bread for example. Sure there will be some crappy sliced white bread on the shelf. But there will also be organic sprouted 7-grain high fiber next to it. In fact, there will probably be more healthy varieties available than just about any other country.
There are far too many products that try to position themselves as "healthy", but are closer to the rest of the crap on the shelves than actual "healthy" food. Even more frustrating is the insane amount of food now using sugar replacements to masquerade as a healthy option.
I personally, find it exhausting to shop at new stores because it can take looking at 2 to 5 items to find one that's actually made healthy.
