You'd probably put me in that crowd, but I think it is a very valid objection. "ultra-processed" is in my opinion a far too large and diverse group to yield good scientific results. It may be a reasonable starting point for investigations, but you really need to look at specific aspects individually to figure out how this works.

We're not going to convert everyone into only eating fresh and non-processed stuff, so you'll have to find out which specific ways of processing or which additions to processed food are problematic and address those.
