I think the "processed food" guidance is widely misunderstood.

From what I gather you shouldn't consider that as a strict rule. It's more a rule of tendencies. Less processed food tends to have more fiber, less sugar, less calorie density. There are exceptions, and obviously it's sometimes debatable what counts as "more processed".

But despite these inaccuracies, it's probably a good simple guidance in a field where there's a lot of uncertainty.
