I know that the USA is by far the largest anglosphere country and so a lot of English-language discussion you see online is very American, but it's a pain in the arse seeing this sort of generalisation about a wildly diverse continent just because a few of the more vocal yanks think the EU sounds a bit like the USA. Does OP think a Finn, a Brit, and a Greek all have a similar diet? Or a similar government, for that matter?
Anecdotalish, but I'm not american. People I know work in the states for a period of time tend to mention they gain weight while in the states for a time, and then lose it when they get home, back to baseline, and they really can't quite put their finger on why. I figure corn syrup. It's like as subtle as the HP sauce, the stuff in England has a different recipe than the American, white vinegar, orange juice concentrate, corn syrup etc in the American one, basically cheaper ingedients, the English original has a subtler, less vinegar harsh, smokier flavour.
