Corn Intolerance But Not Allergy?

Hello,

I tested negative for corn allergies by my allergy specialist. The test was the type where I laid on my stomach and they proceeded to jab sharp objects into parts of my back. Within a few minutes, they could look at the reactions on my back to see if I had a specific allergy.

Wheat and corn were among the allergins I was tested for, and only did I test positive for dust mites. You can see from my signature, that I have a gluten intolerance.

I've been gluten-free since July 3rd, and during that time, I've noticed that my stomach hurts alot after eating a LOT of corn products. I sat down and ate 2 ears of corn on the cob and within an hour or more, my stomach hurt a lot, but it was shortly after going gluten-free, and my body may still have been reacting to the gluten I had on July 2nd.

The same thing happened to me when I ate an entire bag of Tings (they are gluten-free, but they have other products that contain Gluten in them). So there could be cross contamination there. The company says that: "All of our snacks except for Stealth Chips, CHAOS, Honey Wheat Pretzels and Pirate's Pretzels are Gluten Free (There is a Gluten and Wheat free version of the Chaos). Since gluten is used on other snacks at the plant, we do not put it [gluten free] on our bags. They run our snacks first, thoroughly clean the machines between runs, and train all the employees on allergen control to reduce the possibility of cross contamination. However, we cannot 100% guarantee that there can never be a cross-contamination."

I plan to challenge myself this week to see if I get the same symptoms.

I now know that it's possible to have a gluten sensitivity and have it not appear in a skin test, but I wasn't sure it was possible with corn.

Any thoughts from anyone on this topic?

Hi Scott-- The skin tests you had were for true allergies. What you are describing with the corn is an intolerance. I have the same situation in that I have Celiac Disease--but I am not allergic to any foods I've been skin tested for, including wheat. However, I am intollerant to a number of foods causing GI upset and other symptoms. It is not uncommon for a Celiac or someone who is gluten intolerant to have other intolerances--most common are soy, dairy and corn (which is also a grain). I hope that helps :)

Allergies (like the ones tested for my the skin test you had), are IgE mediated reactions. Intolerances are IgG (and IgA) mediated reactions. The skin tests do not show intolerances; they are different beasts all together, and you can have either one or both or neither.

Thank you, that's very informative.

Do you know if there is a test for corn intolerance similar to what I did for Wheat at Enterolab? I didn't see any tests on their website for corn.

      Yes, I, too, have osteoporosis from years of malabsorption, too.  Thiamine and magnesium are what keep the calcium in place in the bones.  If one is low in magnesium, boron, selenium, zinc, copper, and other trace minerals, ones bone heath can suffer.  We need more than just calcium and Vitamin D for strong bones.  Riboflavin B 2, Folate B 9 and Pyridoxine B 6 also contribute to bone formation and strength.   Have you had your thyroid checked?  The thyroid is important to bone health as well.  The thyroid uses lots of thiamine, so a poorly functioning thyroid will affect bone heath.

      That sounds so very likely in my case! I will absolutely ask my doctor on my next bone check coming up in March... Thanks a lot!

      Calcium levels as measured in the blood can be quite deceiving as the body will rob calcium from the bones to meet demands for it by other bodily functions. Also, supplementing with calcium can be counterproductive as it tends to raise gut pH and decrease absorption. More often than not, the problem is poor absorption to begin with rather than deficiency of intake amounts in the diet. Calcium needs an acidic environment to be absorbed. This is why so many people on PPIs develop osteoporosis. The PPIs raise gut pH. And some people have high gut PH for other reasons. Low pH equates to a more acidic environment whereas high pH equates to a more basic (less acidic) environment.

      Kind thanks for all this valuable information! Since my Folate was/is low and also my Calcium, there IS a chance I am low in B vitamins... My doctor only measured the first two, oh and Zinc as I has twisted her arm and guess what, that was mega low too. So who knows, until I get myself tested properly, what else I am deficient in... I did a hair mineral test recently and it said to avoid All sources of Calcium. But this is confusing for me as my Ca is so low and I have osteoporosis because of this. It is my Adjusted Ca that is on the higher side and shouldn't be. So am not sure why the mineral test showed high Ca (well, it was medium in the test but relative to my lowish Magnesium, also via hair sample, it was high I was told). But anyway, thanks again for the VitB download, I will look into this most certainly!

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By ElisaAllergiesgluten · Posted

      Hello good afternoon, I was wondering if anyone has ever brought their anti-allergy pills? I have been wanting to use their Cetirizine HCI 10mg. They are called HealthA2Z and distributed by Allegiant Health.I’m also Asthmatic and these allergies are terrible for me but I also want to be sure they don’t have any sort of gluten compound.    I have tried calling them but to no avail. Has anyone ever used them? If so, did you had any problems or no problems at all?    thank you
