As a European who moved to Canada and spends a fair amount of time in the States, one thing that really surprised me is how hard it is to find healthy food options compared to the unhealthy ones. Food was a bit of a concern before moving, but I didn't know just how frustrating it would be. Even something as simple as Yogurt is usually insanely sweet / sugary compared to European variants. Ingredients that are banned…
Bread is a bit of a shit show. Stick to something like sourdough for 0 adde sugars.
Hormones are banned for meat and poultry. I’m not sure how antibiotics are treated. Fwiw - with vegetarian food you also run the risk of pesticide contamination.
Either way, my point is that there’s a lot of options but do your research before you hit the store and in general try to limit highly processed food
