Processing food doesn't necessarily make food less healthy, but it does it so often that it should not be considered neutral.

  * it frequently removes the fiber and structure, making it faster to eat, and easier to over consume.
  * it frequently adds sugar, salt, etc., not just making it easier to over consume, but with a payload that itself does extra damage.
  * simply changing the form of food, without changing the contents, itself can have serious nutritional consequences [0].

For my own choices ultra processing is guilty until proven innocent. Believing that implies a radical change to how most people eat.
