Maybe "processed foods" is a completely useless term.
I'm pretty sure it's a backformation from "heavily processed foods," which is a useful way to compare foods that have been picked and washed to foods that have been picked and washed and etc, and etc, and etc. Being meaningful makes is less useful for making grand purity pronouncements, though.
All food is processed, all of it is impure, it will make you dirty on the inside, and make you sick. The food that won't make you sick is the food that humans haven't sinned on between God's hand and your mouth.
