Before we come to a final conclusion on this, we need to reexamine the NOVA food classification system. It holds some rather baffling contradictions. For instance, if you buy a deep fryer and a mandolin slicer to make your own potato chips at home, they're classified as processed foods. But if you buy a bag of plain potato chips (ingredients: potatoes, oil, salt) they're classified as ultra-processed.
