I am in no way affiliated with Whole Foods..
Now that that is out of the way.
Whole Foods has gone WAY out of their way to document all of their GF
(and many allergy free) products.
They have an extensive listing, by brand, of their products and whether
they're GF, Kosher, Peanut free, etc...

Again, I'm not affiliated with the company in any way..just really
impressed that they would go to this much trouble for us!
Check it out..

p.s. This URL is a listing of some of the products they carry that are
GF.
