Why corn intolerant after 4 mths gluten free?

I became gluten free about 4 mths ago. when I would eat gluten I’d have anxiety and my heart would race. I quit gluten and now corn seems to be an issue. Has anyone else have to to give up corn after going gluten free from having celiac disease?

This seems to be a common problem for us Celiacs, but a search on Pubmed does not seem to reveal that this problem is being researched or even acknowledged. I wonder if anyone here on the forums knows more about this.

Oh okay. It’s so hard especially being corn intolerant on top of celiac. So grain free it is I guess.

Sequences of proteins in corn resemble sequences of proteins in gluten.  Antigluten antibodies hone in on those sequences no matter the source.  Sometimes, we develop antibodies against other protein sequences in corn as well.

Wow. I am reading this for the first time. Fascinating. That second article you linked to calls out a prolamin, "zein," found in corn, and discusses a blood test for it, called IgA AZA (anti-zein-antibody).  This is the corn equivalent to the wheat anti-gliadin antibody IgA AGA blood test, found in the Celiac blood panel.

This would likely promote corn prolamins to the same status as gluten/gliadin, unless you only find AZA in a Celiac patient, but never in someone without Celiac.

I wonder if there are people who test positive for IgA AZA, but not IgA AGA. If so, would we call them Celiac? Would AZA be added to the Celiac blood panel?

Perhaps Celiac disease is not as special as was initially thought, in that an autoimmune reaction to gluten is unique/different/rare/special, and "no other foods are like that." I think many other foods are like that; this is my hypothesis.

Perhaps Celiac disease is not so much about our immune system reacting to one or more prolamins, but about how that reaction got started in the first place.

Hi Nicole,

It is good that you asked this question as the answers have given all of some helpful information. 

To answer your question I became corn intolerant at least 20 years before I learned I had Celiac Disease. I would buy 3 ears of corn at the Farmers Market and eat them over the next three days, The first day - no reaction. The 2nd day a slight reaction  but soon learned that if I ate corn the 3rd day the reaction was stronger and uncomfortable. 

At this time I had a 'leaky gut' problem. That meant that my small intestine had been damaged by the autoimmune reaction to gluten proteins that let other food antigens to be recognized as harmful invaders by my immune system. During that time I became intolerant of many foods so by the time I learned i had celiac disease I had a very limited diet. I am intolerant of the whole nightshade family (tomatoes, hot peppers, eggplant, etc.) as an example of other intolerances. 

 

There are two other things that I could mention, The first is that you have identified one food intolerance, corn. If you had damage to your small intestine you may have developed other food intolerances. And until you heal you may develop more reaction to other foods or other  substances in your environment. I started an elimination diet eating only lamb, gluten-free rice and zucchini from my garden. When that seemed to be OK I started adding other foods, mostly vegetables then grains or beans instead of rice then other foods and seasonings. Don't make assumptions about whether you can tolerate a food. My assumption about summer squash was ok but my assumption that I could eat small or tiny amounts of corn or hot peppers was very wrong. 

The 2nd thing is that Knitty Kitty and others often give information and links for dealing with inflammation. Take care Nicole.

      Working in a kitchen with gluten?

      By PixieSticks · Posted

      Hi yes! I was diagnosed 10 years ago through a biopsy. I’ve been gluten free ever since but no one I’m around is gluten free. I sometimes wore a surgical mask in the kitchen. but I believe particles were still getting through. I’ll definitely look into n95 instead. thanks for the reply.

      Skinesa

      Ya I used to react to iodine, but it doesn't bother me anymore after strict adherence to a gluten-free diet for many years now. I am happy to report that for the first time ever in my life, a probiotic formula is not making me break out, but actually seems to be helping. The strains in this formula have been specifically tested to help with skin issues. It is gluten and dairy free also.

      Feeling ill

      By knitty kitty · Posted

      @Whyz, I take a combination of Thiamin (Benfotiamin), B12 Cobalamine and Pyridoxine B6 for my pain and headaches.  Really works well without hurting the digestive tract.  Riboflavin B2 also helps with migraines.  Most newly diagnosed people have vitamin and mineral deficiencies.  Check with your doctor and nutritionist.   If you follow the updated gluten challenge guidelines, you can wait until two weeks (minimum) before your appointment, then eat lots of gluten, like six slices of gluten containing bread or "name your poison".   Here's the Updated Gluten Challenge Guidelines: Recommended intake of gluten should be increased to 10 grams of gluten per day for at least two weeks. Or longer. While three grams of gluten will begin the immune response, ten grams of gluten is needed to get antibody levels up to where they can be measured in antibody tests and changes can be seen in the small intestine.   Keep in mind that there are different amounts of gluten in different kinds of bread and gluten containing foods.  Pizza crust and breads that are thick and chewy contain more gluten than things like cake and cookies.   References: https://www.beyondceliac.org/celiac-disease/the-gluten-challenge/ And... Evaluating Responses to Gluten Challenge: A Randomized, Double-Blind, 2-Dose Gluten Challenge Trial https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7878429/?report=reader  "In our study, limited changes in Vh:celiac disease (villi height vs crypt depth - aka damage to the small intestine)  following 14-day challenge with 3 g of gluten were observed, in accordance with Sarna et al.  While the 3 g dose was sufficient to initiate an immune response, as detected by several biomarkers such as IL-2, the 10 g dose was required for enteropathy within the study time frame. Based on our data, we would suggest that gluten challenge should be conducted over longer durations and/or using doses of gluten of ≥ 3 g/day to ensure sufficient histological change can be induced." Keep us posted on your progress!

      Advantages vs. Disadvantages of having an official Celiac diagnosis

      By Scott Adams · Posted

      I don't believe that existing life insurance policies require such notifications--health checks are typically done before such policies are obtained. I believe it would primarily affect any new policy you get, and perhaps any policy renewal.

      You could go gluten-free now, and then start eating lots of gluten for at least 2 weeks before your endoscopy--just be sure to tell your doctor about this beforehand. If your symptoms go away on a gluten-free diet, it is further evidence of celiac disease and/or non-celiac gluten sensitivity.  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
