To say that this makes processed foods bad for you however is kinda ridiculous imo. Might as well tell people to only eat raw things because it has the least calories / most filling.
Bad food is bad for you, eating junk food is known to be a giant waste of calories and how it's prepared doesn't make it better or worse.
Outside of increased calories I have not seen any evidence that food being more "processed" is actually bad for you.
I'm not sure when this movement against junk food became a movement against processed foods but it's moving in the wrong direction. Plenty of shitty junk foods can have very little processing involved. And I'm convinced it's exactly those "low processed" junk food providers that are pushing all this bullshit.
