I say "whatever" and eat rice pasta and gluten-free Udi's white bread instead.
There are some excellent tasting gluten-free rice pastas available at Whole Foods and probably some other groceries as well.
Udi's gluten-free bread gives me trouble probably because it contains other junk that I cannot tolerate besides gluten. I am lucky to live where bread from DeLand bakery is available. They cannot officially say their bread is gluten-free because it is baked in ovens that also produce wheat and gluten foods.
If their bread does contain any trace gluten then it must be in such small amounts that it doesn't affect me at all, unlike ordinary wheat bread and pizza which drives my gut crazy. Check out the ingredients, you cannot get anymore 'clean' than that.https://www.delandbakery.com/p/004an.html
