The use of the word "processing" is ambiguous.

There are 3 kinds of processing, with very different effects. One kind is separating a product into its components. Another is mixing various ingredients. The third is applying some treatment to the product that modifies its structure, heating being the most frequent method.

I consider only mixing ingredients and applying various treatments as belonging to "ultraprocessing", because these processing methods remove the control of the end consumer about what is being eaten, as they are normally irreversible.

On the other hand, any separation method cannot have a harmful effect by itself and separation of the edible components is absolutely necessarily for human food, because we have reduced digestive systems, which are unable to extract as efficiently the nutrients from food as those of most other non-carnivorous mammals.

The only harmful effects of well-separated food ingredients, like seed flour, oils or protein powders, happen when the end consumers choose to mix them in unhealthy proportions, like when adding too much sugar or too much fat to some dish, but then they can blame only themselves for this.

With food that has passed through the other kinds of processing, nothing that the end consumers do with it can make it healthy, when it has not originally been so, which happens frequently because for its producers it is more beneficial to try to make it addictive instead of healthy.

In your definition what is the difference between "ultraprocessing" and "processing"?
