Sounds like you're defining processed food, whereas this is about ultra processed food. For me, processed food might include something like unsweetened peanut butter where while the only ingredient is peanuts, it's still been through a process of grinding so that it's no longer in its natural form. At the other end of the spectrum an example of ultra processed food would be a factory packaged item with a long list of ingredients which includes ones you don't recognise e.g. chemical names or E numbers.
