We are testing out reducing the volume of processed or chemical additive foods he eats, but aren't trying to cut out wheat or milk. As you can tell from reading what he eats, that would be really hard. Wheat and diary are a HUGE part of his picky eater diet.
One common and noticeable feature of addiction is how it puts you off other things.
Specialists in food allergies/intolerance routinely suggest that if there is a food which you eat every day, which you eat more than any other, then it may well be the culprit in a host of other problems.
It is apparently like a flashing light to nutritionists experienced in food allergies/intolerance, the sign they look for above/before anything else; a narrow diet with preference for one or two things, and an avoidance of or indifference or even disgust for almost everything else.
It was certainly the case for me, pizza, burger, toasted sandwiches, etc. I ate almost nothing else.

You insist on always knocking me off guard, don't you, lol? But, you have a really good point, and I should definitely look into it.
