4 ingredients that would only make it processed

Kitchen staples like sugar, salt and oil. On their own they make a food processed, not ultra-processed.

  • Meals Products in the category "Meals" are at least group 3.
  • Preservative Preservatives slow spoilage by microbes.
  • Salt Salt, added for taste and preservation.
  • Cheese Cheese is milk preserved with salt, cultures and rennet.
