A cow is in a sense a factory producing various proteins, fats, and carbs from grass. Does putting it into something "natural" reset it? I would imagine that red meat isn't a UPF by definition as it's only been through one process, but would argue that the inconsistency with fake meat clearly feeling processed is definitely interesting. Also interesting is perhaps that red meat is presumably not UPF but is carcinogenic.

In that sense a plant is as much a factory as an animal, and all foods are processed before they are harvested.

If this is an argument that "processing" isn't really a useful concept, I'll disagree, because it's clear that post-harvest processing has a very significant effect.
