You're missing that from the conversation, where myself and others have stated it repeatedly, not from the wikipedia page.
> How is the food unhealthy? By having lots of fats?
Yes.
> Or high salt?
Yes, that too.
> Or high sugar?
Yes, very much this.
> Is it perhaps the ingredients that make it unhealthy?
Also true. For example: while preservatives like sodium benzoate are not used in unhealthy quantities in any individual item of food, a diet high in ultraprocessed foods can consume unsafe levels.
Sure my point is that what we’re actually talking about is the ingredients themselves, not how they’re processed. Except it’s through this roundabout way; if your worry is sodium benzoate, it doesn’t matter if the food was extruded, deep fried, or emulsified, all that matters is if it has sodium benzoate.
And we don’t need a proxy for that. We need proper labelling of ingredients.
