> "You can, however, find packaged sugarfree yogurt" That stuff is a miracle of modern chemistry. It has, however, only a passing resemblance to actual yoghurt. Nobody who grew up in Europe really wants sugar-free. It's "no sugar added" that matters. Nobody wants fat-free, either. And there are quite a few studies making the point that these "healthy" food actually contribute to weight gain.
"Starbucks is on every corner and sells plain vegetables, plain fruit, plain eggs"... if you're lucky. Usually, it's sold out fairly quickly.
In general, yes, getting healthy food in the US is much harder than it is in Europe. The vast majority of food here is processed to within an inch of its life, and the remainder is incredibly expensive, because it's treated as a luxury good.
I've spent a few decades in Europe, as well as a few in the US. I'm fairly confident I know which food I can get where in either place - and the US is severely broken. Trust me, I wish it weren't. But healthy food is difficult, and becomes extra-hard as you leave bigger cities with specialty stores behind.
