Protein powder? Ensure / Boost? (important for people who can't chew food) Canned or similarly preserved foods? (important for people without access to reliable refrigeration) Even staple grains (wheat, rice, corn) are pretty highly processed. One can't exactly eat these raw, they need some machinery and sometimes chemistry to really get at the nutrients. I guess this all depends on your definition of "ultra-processed" and "good for people." But the processing of food is a discovery that allowed for the civilizations to appear. Feeding people on fresh meat and veg doesn't scale.
