There's also ways to avoid US poisons, such as avoiding fast food trends or buying alternative brands of things that prep it differently.
With enough planning you can avoid a lot of the problems, you don't even need to drink out of the tap if you're that kind of worrier.
Its more than just food. Water comes in ~plastic bottles~ fuxking everything on the market has fragrance in it and when you look into those 90% cause cancer.
You could opt for water purifiers and a well, that's how my family has it. This has meant having to deal with Limestone and some other minerals but that's only really annoying for washing my hair.
Even for food prep, I've begun to worry more about how they make Salt and Sugar here (and in some other countries with similar practices) since my trip to Japan. Their version somehow was able to do the job without feeling as supersaturated or something, it didn't have the same kick while still providing for the body. I was able to eat candy without it sating the sugar addiction, like biting into a piece of fruit, and while that was disturbing it was also a wakeup call over my diet.
There are ways around every thing you don't want to have to deal with by planning around it, someone else out there cares and likely provides a service for a niche audience, especially with the growing concerns in the US overall when it comes to desires of self-sufficiency as safety.
Edit: That being said, there are some good things about the supersaturated-like practices here. For example, US recreational drugs are actually pretty good over having them be about having a loopy good time, while my time traveling and even talking to people from other countries had me find and hear about them reducing the potency of things like marijuana (if their country even has a scene in it) so that it can be more like a relaxed buzz, while the US is becoming really into Terpenes and Potency, more into it for the party mindset by comparison.
