But the reasons can be very different. East Europe had severe food shortages until the fall of communism. The result? People eating too much after the fall of communism, which become a cultural thing ("you don't have huge meals => you are poor / is like during communism"). Add to that car ownership ("public transport => only poor use it") and you get what happened probably in USA due more to lobbying and industry.
One good thing in my opinion is that is much easier in EU to at least choose. I was amazed in USA how badly marked are the components (in EU you have at least on each thing sugar/100g, fat, salt, etc.) and how unavailable are fresher things (even if they would be expensive). So while in EU I would say "repeat more to people to eat varied and not abuse salt/fat/sugar", that would not work as well in the USA (or, you need to teach them math and unit conversion as well :-p)
