I never can get anyone to give me a proper definition of processed food that doesn’t include obviously okay stuff like bread or yoghurt. As I wouldn’t call those foods prepared, 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
