The second reason is that while both the US and EU have farming subsidies, the way these subsidies are structured means that in the US they tend to incentivize the use of high fructose corn syrup

Yes, but that is actually not solely subsidies- but also overregulation. Sugar imports are taxed. Though, it would be better for people’s health to try to transition away from caloric sugars to substitutes like aspartame.

the production of highly processed foods

Source?

highly processed foods tend to be more expensive and “whole foods” tend to be cheaper.

This is just the blog of a guy selling a book.

As a result people in the EU tend to eat less processed food as a percentage of their caloric intake:

So we were talking about supply, not consumption. But regardless, yes americans choose to eat processed foods more on average. So? The predominant cheap form of calories/proteins in Europe are cereals and tubers, those aren’t exactly lacking in the US. (Btw, its just because they’re cheap everywhere,

Though its not like either Americans or Europeans are significantly different in food group consumption for the most part The other differences being a much higher preference for meat in the US, also supported by the US actually getting majority of its protein from meat sources

Americans can afford raw potatoes too, they choose not to buy it. In fact, despite buying meat something supposedly 25% of Europeans cannot afford to eat every second day(though I don’t believe that statistic to be honest)- Americans spend significantly less of their budget on food.

And to preempt a possible argument, American antiobiotic use in livestock is on par with some of Europe and much lower than some of Europe
