That said, I think I value food that has fewer steps in preparation as being "more real" so I'd prefer something like a meat and onion skillet to beef wellington or a clumped cream chicken pot pie.
I think the title is terrible for choosing that specific word - I'd much prefer a title like "How Crisco Made Americans Believers in Artificial Food". And in actuality it's more of an issue of the government not preventing wholly unhealthy food from finding the wide markets they have.
What if I make them at my house and take them to someone else's home?
You can only be sure that sausages are "real food", if you make it yourself at home using the raw ingredients. Otherwise, no idea.
Edit: I see that you're a former lawyer. I'm going to assume it's a semantic word-play thing
But if you want to talk about curing meats, that's a fun topic. The ones my fam makes are way tastier than Jimmy Dean's
IMO any processed food that hasn't been around for a couple of generations should be treated with some suspicion.
If you want to define "processing" a loosey-goosey definition might be "anything that can't be done in the average kitchen using ingredients commonly found at a grocery store". By this definition, maybe breakfast cereals aren't processed - you could make Grape Nuts in your kitchen if you were sufficiently determined and masochistic. But it's a decent heuristic otherwise.
