Is mined food processed food?
Every* food is processed food the amount of processing varies.
Sure, if you want to be asinine about it. The term 'processed' is probably too broad, same as calling food 'healthy' or 'unhealthy'.
Does that apply to to self-harvested apples and berries, too? Is washing them with water a process which changes their structure and composition of nutrients? Less proteins because of less bugs and worms?
They’re selectively bred for one thing, and they start changing the moment you pick them. Just sitting on your counter changes a piece of fruit. Touching a berry with your finger introduces millions of tiny bioreactors onto its surface, some will go to work breaking cell walls, fermenting, fighting with the local and antecedent microscopic flora, and so on.
Or cooking it, for that matter.
Plus there's the "processing" of an enormous mobile smelter-factory of nanomachines we call the human body. Chop and grind, add peptides, acid-bath, add neutralizing agent, churn with fermentation bacteria...
Yeah, I know, people usually implicitly mean "artificial" processing, but that's often more about who is doing the processing, rather than what kind of process is going on.
Mined food would likely be considered "processed" in some sense, because the raw materials would have to undergo some form of alteration
