> which is not super desirable as human food without significant processing I see this repeated all the time. Is making cornmeal or cornflour really that much more involved than wheat flour, semolina, or rolled oats?
It's really not about that, corn products are simply bad for health - too much sugar, to little more valuable nutrients.

Now corn products are now a key component of his diet.
