That's one advantage to being gluten sensitive - I don't bother buying those kinds of things now and generally just cook from simpler ingredients.
It is annoying to go out to a fancy restaurant and find that they use wheat based tortillas rather than authentic corn - you'd expect them to be making things themselves rather than just buying them from a shop.
Just thought of another one - Thai-style fishcakes (e.g. in restaurants). Why are they covered in breadcrumbs when Thai food hardly ever uses wheat?
These kind of foods should be home made. Wheat is lesser issue with them.
Even simpler foods like garlic-paste, if bought ready-made in store it contains lot's of unnecessary ingredients.
People buy junk food (pre-made meal) and blame wheat.
