Ultraprocessed for me means "truly delicious and dopamine-inducing". Not that I don't find other food tasty, but something that feels engineered to please your tongue is usually ultraprocessed.
I wish they just showed a graph of "decline in cognition" vs "percentage of calories from processed foods" instead of making me try to parse the relevant information out of sentences like that. What 10% of my calories come from processed foods? I'm I completely safe or is the effect linear in percentage of calories or what?
That describes nearly all modern cultivars of fruits/vegetables.
