This is a bit disingenuous. When listed like that on food it's because all of those were added in individually to create an ultra processed amalgamation resembling food. Otherwise ingredients would just say bannana.
Processed foods have been clinically shown to be harmful to us. Bannanas seem to be okay
I wouldn't call bread or yoghurt prepared instead of processed personally though, they've been through multiple chemical and biological processes.
Ultra processes foods is something that tends to be more appropriate I think. That's stuff like chips or fast food. Though even that I consider fine to eat in moderation, and I, personally, do. Though I agree it would be better if I completely cut those out. I just tend to eat a lot of pre-made foods due to disability reasons (frozen pizzas, pastas, and the like)
But yeah, I do know that the US has some very lax food laws unfortunately. So maybe that is a big part of the difference
