They seem to be trying to not indict high carb foods that almost instantaneously vanish into the bloodstream as glucose.
It is just weird that they keep using a term that is never defined.
In my opinion, if I can make it in my kitchen without specialized equipment, it does not fall under "ultra-processed". Other people think that it means something else. Someone told me fried chicken is "ultra-processed" but for some reason fried fish was not and baked chicken was not.
I just would like the terms to be standardized and make sense.
