That isn't what you were saying. That doesn't say corn is bad, it says there might be a wheat, barley or rye addded to a corn product, so don't assume. Read ingredients.
Honestly, I don't know if we aren't explaining something well enough, we are all misunderstanding each other, or you are too upset to really read what people are trying to say. I don't think there is anything else I can do, tonight, to help you. Tomorrow is a new day.
I completely understand what you're saying. First of all you're blowing off 'the product guy's' research, which may or may not be accurate. Assuming it is not accurate, you're saying corn by itself is gluten free but can easily be contaminated because it is often manufactured in facilities that also manufacturer wheat products.
Great! I want to know that. And I want to learn it from the gluten free organization I choose to trust. When I read that corn is on the acceptable list, I want an asterisk next to it warning me of cross-contamination.
When I go to the mall to buy a product containing corn, I want a disclaimer next to the product again warning me that it may be contaminated.
Not every single food product falls into the 'iffy' category.
I expect to be advised about those that do.
My company sells products to pet owners. We have warnings everywhere to advise them of any possibility. Should I just let them find out by trial and error? I don't think so. Forewarned is forearmed.
I did not know about cross-contamination of corn products until today, yet I consumed a lot of corn because it's on the 'safe' list.
How much more can I explain my point of view? I don't mind that corn is on the safe list. I do mind that there was no warning about cross-contamination, since it seems to be more problematic than with other foods.
