I find the assumption that Europeans eat better, that they have access to fresh, local produce is pretty funny, at least as it applies to Brits. Tiny little island, homogeonized climate /= year-round access to huge varieties of fresh, local produce. My DH and I don't buy a lot of prepared food (we like to cook, have lots of free time, and if we don't feel like making dinner and are low on left-overs we can afford to go out), but it's not from a lack of available processed food. Nine months out of the year, the "fresh" produce is from Chile or Argentina - the same places my out-of season fruits and veg were coming from when I lived in California.
Part of the problem with the "foodie" and "eat local" movements is that it's elitist - there are few places in the world where you can get fresh, local produce, and even when you can it's much more expensive to eat that way than it is to buy a frozen dinner, or a box of Hamburger Helper, or take the whole family to McDonalds.
For the record, I was raised on peanutbutter that came out of grinder (ironically, all the green things that are so popular with the yuppies today were things we did 30 years ago because we had absolutely no money) and I think Skippy creamy peanutbutter is the most amazingly delicious thing ever.
