alt Hacker NewsYou are definitely right that there are places in the US with great produce e.g. rural cali - much better than Germany's - but I still feel that on average there is higher quality food in Germany, less ultra processed food and a healthier food culture in general.
Of course I haven't scoured the states (not even Germany for that matter), so.. :)
I don't know German produce but I'm pretty confident California, where I'm from, doesn't compare to Paris' farmers markets. The variety and quality there were way beyond all the farmers markets and produce stands I've been to over my life in California. That said, I certainly noticed a difference between California and Maryland, at least at the time. But, having experienced better I no longer consider California good. As one example, I have very bad luck trying to find a tomato with any flavor.
