Oatmilk and oats

Hello, my son was recently diagnosed with celiac disease he is 6 and he loves oats and oat milk. I know that oats can be on the fence for cross contamination. What has been your experience? Any advice?

Welcome to the forum, @HannahF!

The problem with oats can not only be "cross contamination" but also "cross reaction". Cross contamination refers to the inadvertent inclusion of wheat, barley or rye in the oatmeal. Cross reactivity refers to the fact that the main protein in oats (avenin) is similar enough in structure to gluten such that it causes gluten type reaction in about 10% of celiacs. 

A statistically more concerning cross reaction issue in the celiac population is dairy. The protein casein in dairy is similar in structure to gluten and some small studies suggest that 50% of celiacs react to it like they do gluten. Many celiacs are also lactose intolerant, at least until there is substantial healing of the villous lining of the small bowel after going gluten free. Lactose is the sugar component of milk.

I agree with @trents--Oats naturally contain a protein called avenin, which is similar to the gluten proteins found in wheat, barley, and rye. While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure.

Your son may fall into this category, and eliminating them is the best way to figure this out. Some people substitute gluten-free quinoa flakes for oats if they want a hot cereal substitute.

If you are interested in summaries of scientific publications on the topic of oats and celiac disease, we have an entire category dedicated to it which is here:

      Hi @Karmmacalling I'm very sorry to hear you are feeling so unwell.  Can you tell us exactly what sort of pain you are experiencing and where the pain is?  Is it your lower abdomen, upper abdomen etc?  Do you have any other symptoms? Cristiana

      The NIH article you link actually supports what I have been trying to explain to you: "Celiac disease (celiac disease) is an autoimmune-mediated enteropathy triggered by dietary gluten in genetically prone individuals. The current treatment for celiac disease is a strict lifelong gluten-free diet. However, in some celiac disease patients following a strict gluten-free diet, the symptoms do not remit. These cases may be refractory celiac disease or due to gluten contamination; however, the lack of response could be related to other dietary ingredients, such as maize, which is one of the most common alternatives to wheat used in the gluten-free diet. In some celiac disease patients, as a rare event, peptides from maize prolamins could induce a celiac-like immune response by similar or alternative pathogenic mechanisms to those used by wheat gluten peptides. This is supported by several shared features between wheat and maize prolamins and by some experimental results. Given that gluten peptides induce an immune response of the intestinal mucosa both in vivo and in vitro, peptides from maize prolamins could also be tested to determine whether they also induce a cellular immune response. Hypothetically, maize prolamins could be harmful for a very limited subgroup of celiac disease patients, especially those that are non-responsive, and if it is confirmed, they should follow, in addition to a gluten-free, a maize-free diet." Notice that those for whom it is suggested to follow a maize-free diet are a "very limited subgroup of celiac disease patients". Please don't try to make your own experience normative for the entire celiac community.  Notice also that the last part of the concluding sentence in the paragraph does not equate a gluten-free diet with a maize-free diet, it actually puts them in juxtaposition to one another. In other words, they are different but for a "limited subgroup of celiac disease patients" they produce the same or a similar reaction. You refer to celiac reactions to cereal grain prolamins as "allergic" reactions and "food sensitivity". For instance, you say, "NIH sees all these grains as in opposition to celiacs, of which I am one and that is science, not any MD with a good memory who overprescribes medications that contain known food allergens in them, of which they have zero knowledge if the patient is in fact allergic to or not, since they failed to do simple 'food sensitivity' testing" and "IF a person wants to get well, they should be the one to determine what grains they are allergic to and what grains they want to leave out, not you. I need to remind you that celiac disease is not an allergy, it is an autoimmune disorder. Neither allergy testing nor food sensitivity testing can be used to diagnose celiac disease. Allergy testing and food sensitivity testing cannot detect the antibodies produced by celiac disease in reaction to gluten ingestion.  You say of me, "You must be one of those who are only gluten intolerant . . ." Gluten intolerance is synonymous with celiac disease. You must be referring to gluten sensitivity or NCGS (Non Celiac Gluten Sensitivity). Actually, I have been officially diagnosed with celiac disease both by blood antibody testing and by endoscopy/positive biopsy. Reacting to all cereal grain prolamins does not define celiac disease. If you are intent on teaching the truth, please get it straight first.

      Perhaps you would still like to answer the questions I posed on this topic, because that is all I asked. I am curious to know the answers to those questions, I do not care about the background of Dr. Osborne as I am more aware of the situation than you are, and he is also one of the best known authors out there on Celiac disease. But did you even bother to read the three Research Papers I posted by NIH? You must be one of those who are only gluten intolerant and not yet reacting to all glutens aka grains, but I AM one of those who react to ALL the glutens, and again, that is one of the two questions I originally posted on this matter. NIH sees all these grains as in opposition to celiacs, of which I am one and that is science, not any MD with a good memory who overprescribes medications that contain known food allergens in them, of which they have zero knowledge if the patient is in fact allergic to or not, since they failed to do simple 'food sensitivity' testing. I started with the failed FDA explanation of what Gluten Free is and I stayed sick and got even sicker. It wasn't until I came across NIH's papers and went off all grains that I realized that in fact, I am Celiac and reacting to all the glutens. IF a person wants to get well, they should be the one to determine what grains they are allergic to and what grains they want to leave out, not you. Those who are just getting started with learning about grains etc., can take it easy by just being "grain free' and eating a lot of meat, vegetables, etc. or whole foods as God has intended, without buying so called gluten free garbage out there that is making them sick and the whole reason they are not better. I tried the stupid gluten free garbage and it didn't work, and that will make anyone want to give up, it is better to teach the entire truth and let the patient decide, rather than give them misinformation and lies.
