> You get to problematic through hyperpalatability, which is another, different target of modern food engineering

I don't think even that is problematic by itself. You need to apply hyper palatable techniques to high calorie nutrient poor food for it to be a problem.

Getting people addicted to something that's mostly protein or fiber or water packed with important micro nutrients would not be a bad thing at all. That's not what the food companies are doing (because empty calories are cheaper) but it's a perfectly good strategy we need more of.
