deep problems with food
As far as I know, there are some issues (which have become political) about permitted additives and what can and can't be imported. Also chlorinated chicken and some issues with beef.
you can eat well and healthily in the US
I've eaten nicely there, especially pizza in New York. As in Poland and probably the U.K. though, it isn't actually cheese on a lot of pizza; instead, they use 'non-dairy pizza topping'.
They have five times the sugar limit allowed in Ireland for bread!
Burger buns in McDonalds ar much the same.
There's a lot of product on Netflix and the other streaming services. In Britain at the start of the 90s they had to reduce the amount of American stuff on TV since it was harming quality (in part because of the footage from the cutting room floor they used to put back in due to differences in programme length and the adverts and in part because buying in is cheaper than making original content). This appears to have fallen by the wayside.
Unfortunately it's hard to avoid Microsoft completely (though I mostly do) and Apple (which is much better). There's always Deepseek rather than ChatGPT however that of course is Chinese.
