Hi DDK, Gluten remains in white flour.
This may cause issues whether you are celiac or not...
Here you can read about the evil Lord Zonulin:
Leaky Gut Syndrome - Is Gluten at the Root? | Gluten-Free Society
DDK, have you tried replacing white flour with potatoes for a few weeks?
I don't believe in any of the anti-wheat/gluten propaganda, I have only seen benefits from white flour. However, I have seen tremendous damage in myself and others from whole grains. Yes, gluten remains in white flour, but you said anti-nutrients in your first post; most of those substances lie in the bran.
Yes, I do fine with both potatoes and white flour. I have eaten just potatoes as my only starch as well as white flour, I tolerate both fine; at the moment I am eating both. White flour however is more versatile (Bread, Pancakes, Pasta, Pizza, Cookies, Cake Donuts, Brownies, Waffles, etc...) I make all of this homemade with good ingredients BTW.
