They're processed, yes. The corn is milled, pressed into triangles, coated with preservative-heavy flavor powder and cooked in one order or another, possibly repeatedly.
What makes it ULTRA processed?
Frickin... most raw potatoes are "processed" because they're typically not covered in topsoil when they get put in 5lb plastic bags.
A grass-fed organic, antibiotic free, roaming free-range massaged poterhouse steak is "processed" because it's not still attached to the cow.
I'm trying to understand the definition, here. Almost everything is processed to some degree or another.
Is white flour ultra processed because they bleach and de-hull the wheat berries? Or only when it's made into cake flour? Or do both of those count as "processed" and only "cake MIX" counts as "ultra processed"?
