"Another example of how broadening the initial definition of a highly or ultra-processed food may create confusion is the use of terms that, in themselves, are not precisely defined. For bread, initially defined as such in the NOVA food classification, examples might be the use of terms such as sliced, mass-produced, or sweetened. Their exact interpretation is not self-evident. [...]" [1]

Again, there's no unambiguous definition here. The UN has drawn one line out of many potentially valid ones. My point here isn't to argue word semantics. I'm just saying look at what the average person would consider "ultra-processed", whatever their definition (or lack thereof) might be.

P.S. I'm not even sure what you consider "ultra-processed bread" is good for people in any case.

I mean the whole wheat bread I eat everyday is sliced, mass produced, and sweetened a little bit (as are almost all whole wheat breads, regardless of whether they’re mass produced) - I’m pretty sure it’s as good for me as any other whole grain.
