Oven fries we do make, unpeeled organic Russet potatoes in olive oil and salt. I’d file those under minimally processed. Not even as processed as the sourdough bread I make.
But the delicious fries fro McDonald’s that are so far removed from being a potato seem more processed.
Ultra -processed I thought was like a Twinkie or Pringles or a frozen packaged dinner. Those sort of foods I have maybe once a month if you count diet coke, but only ever that occasional diet coke and at Halloween my kids save me the mini Milky Way Midnight if they get any. So not none, but approaching none.
