I was confused too, but it's going to depend on "How" processed it is. If the flour still has all the bran, germ, and fiber. I would say it's not very processed (Minimally processed). If it's bleached, I would say that treading in Ultra-Processed Foods territory.
Unprocessed or minimally processed foods: Think vegetables, grains, legumes, fruits, nuts, meats, seafood, herbs, spices, garlic, eggs and milk.
Processed foods: When ingredients such as oil, sugar or salt are added to foods and they are packaged, the result is processed foods. Examples are simple bread, cheese, tofu, and canned tuna or beans. These foods have been altered, but not in a way that’s detrimental to health.
Ultra-processed foods: These foods go through multiple processes (extrusion, molding, milling, etc.), contain many added ingredients and are highly manipulated. Examples are soft drinks, chips, chocolate, candy, ice-cream, sweetened breakfast cereals, packaged soups, chicken nuggets, hotdogs, fries and more.
I'm using classification system called [NOVA]<http://archive.wphna.org/wp-content/uploads/2016/01/WN-2016-...> that was developed by an international panel of food scientists and researchers. It splits foods into four categories:
Unprocessed or minimally processed foods: Think vegetables, grains, legumes, fruits, nuts, meats, seafood, herbs, spices, garlic, eggs and milk.
