Because the term "unprocessed" carries its own ambiguities. Is cooking a steak a form of processing? I would say so. What about the mashing of potatoes? Ultimately, processed and clean are largely subjective.

Meh, the degree of processing can be hard to measure. Yes, I agree. But it's far more useful than clean and unclean. Because these are fantasy.

People just call clean, whatever they like/think is beneficial. Everything they deem harmful is unclean.
