"Corn Gluten" is an abuse of the term "gluten" since corn doesn't contain gluten. Yes! Good news! I am eating popcorn tonight! (with coconut oil, not butter)

I am not celiac. I don't know to what I'm actually allergic. I have sensitivities which I attribute to a leaky gut attributable to years of abuse (Standard typical "healthier" American diet) and finally a candida yeast overload. I'm still diagnosing and treating myself. I've been eating corn chips on occaision.

Issues with corn could be:
-allergy to corn because it's added to so many processed foods in so many different forms
-reaction to toxic chemicals (could try "Organic" products which will also help you avoid Genetically Modified Organisms)
-reaction to GMO's (could try "Organic" or better products)
-molds can be typical for dried corn products
