Sometimes, yes, it is. Real cheese is in a way a creation of a new food item as one raw ingredient (milk) is used by microorganisms to create another food product. Skimmed milk though can be considered a processed food item as it is a "waste" by-product of extracting cream from it. Cooking is also "processing" raw ingredients. But we know that "processing" by cooking raw ingredients to prepare dishes is beneficial for us despite the slight loss of nutrition (it allows our body to digest food more easily, and thus absorb nutritions better). We also know over-cooking (burning) food makes them carcinogenic. Factory "processing" of food essentially tends to strip off nutrition from food, in favour of taste (and sometimes digestibility). Ultra processed food tends to do this to an extreme. (For example, fruit juice seem more tastier because when we eat fruit the fibres slow down the release of sugar to our body. Fruit juice essentially strips of this fibre allowing our body to absorb sugar faster.)
