Aren't chips blown to smithereens and then reconstructed with the help of all those random ingredients? I think this is what "ultra-processed" means and what differentiates these foods from getting your bag of potatoes and frying them at home.

I don't know about Pringles / Lays &c, but I've never seen two potatoes of the same size and shape in a bag, so there must be some way they manage to get all their chips to look the same.
