The recent info on corn.
In February of this year a new study was done on those people with Celiac and how corn affected them. The reason for this study was that some people who have Celiac are still not getting better. Why is this happening? It turns out that the gluten in corn is similar enough to the gluten in wheat, barley, and rye so create a reason in those celiac patients.
One of the reasons this missed is because of the way we test for Celiac. Since doctors measure blood for gluten reactions only certain reaction can be seen. The reaction to the gluten in Corn doesn't show up the same way.
Celiac can come in a variety of forms
Since we are still learning so much about this issue we have a long way to go. A good percentage of celiac patients are not getting better by eating a gluten free diet. That means that something in the diet is still causing issues. If this is the case I strongly suggest that you cut corn and all things containing corn or "Maze" from your diet. This can be really hard since corn is in just about everything. By trying to live Gluten and corn free this will very much narrow down what you can eat. However, if it makes you feel better than it is worth it. If cutting corn is not helping then you might need to go back to see your doctor to find out what is going on.
