Thank you for attempting to answer the question. I'm having trouble understanding the N.O.V.A. criteria in a consistent way.
Nova classification Grup I includes "milk" as "unprocessed food." That sounds to me like unpasteurized or "raw" milk, and that is not as safe to eat. Later it says some processing is allowed while still calling is "unprocessed." It mentions pasta as "unprocessed" and brother, grains have to be rendered unrecognizable multiple ways before it becomes pasta.
Grup II claims "pressing" is a threshold of processing, yet "grinding" is still Grup I. Pasteurizing is still Grup I but bringing anything other than milk to a boil is Grup III. I find it confusing.
