We have nice bread in the US. Sometimes people outside the US don't realize the massive amount of choice we have here. There are like 50 different kinds of bread in the supermarket I go to. Unbleached organic flour is also readily available if you'd like to make your own bread. There's 10s-100s of types of fresh vegetables probably. There are organic variations of almost every available vegetable and herb as well. We have pretty good regulations around food labelling, so you can find healthy things. You just have to be vigilant. It isn't that hard to eat a diverse, healthy diet, once you know what to avoid. Bad things to eat do exist here though, and they're quite addictive. I think our car centric culture lends to eating fast, processed things. You can eat a full diet of rice, beans, vegetables, and meats very cheaply in the US. It gets about 2x more expensive when you go for organic foods, though. It's still significantly cheaper to eat a healthy diet of all unprocessed organic foods than it is to regularly eat at restaurants.

Before I had an interest in researching a healthy diet I made poor dietary choices. I don't think the good choices are always immediately obvious. I also spent about 3x my normal time in the supermarket when I first started eating healthy. If you live somewhere with few grocery options you may have to drive pretty far. When I was a kid we commuted 40-50 miles (1hr drive) to go to a better, cheaper grocery store.

There are bakeries in the US, you know.

In both Australia and the US, mass market/supermarket bread is crap. Of course there's plenty of decent sourdough etc to be found (Sonoma etc), but you have to look for it and it will cost you a pretty penny.

I, like many, made sourdough during the pandemic, and vastly prefer it to our native 'sugar cake.' I'll be on the lookout.
