I don’t think there’s anything wrong with processing by itself, it’s what goes in the food that is problematic. I think just saying processing is harmful is like saying baking is harmful. They should be focused on what the food actually is, not how it is made.
“Ultra-processed foods typically contain things like artificial sweeteners, synthetic colors, flavors, emulsifiers, and other ingredients that people don’t cook with at home, Nestle said.”
So maybe focus on the harmful ingredients, not the way it is made.
