Confused About Casein

After being gluten free for nearly 6 years, it turns out that I'm still having problems absorbing vitamins and found out that I don't absorb zinc or folic acid, along with my malabsorption of B12. It caused a sluggish thyroid, among other problems. It might be that I have a problem with dairy. After a 3-month trip to China, my digestion improved ten-fold and I realized that I don't consume milk products there, aside from chocolate. So I cut most dairy from my diet and my digestion improved, though I'm not yet sure about the malabsorption. But I'm confused as to the root of the problem. My main symptom with dairy appears to be constipation- but I'm having severe fatigue issues as well (though that might be my battle with the thyroid.)

I suppose my main questions are:

1. Can casein cause a similar immunological reaction in the same way gluten would for Celiacs (meaning only needs to be absorbed into my bloodstream) or is it more like an intolerance and must go through my digestive tract?

2. My sublingual vitamins use lactose as a binder. Is it possible to separate lactose from casein?

I suppose I'm just confused about why Celiacs go on a casein-free diet to begin with if it doesn't cause a similar immune response. Is it merely an intolerance or is it something a little more sinister? I have several other food intolerances but they don't usually bother me unless I eat a lot of it. But I only need to lick an envelope with gluten on it to get sick.

I'm confused! Help!

From what I've read, the protein structure of casein is similar enough to gluten to cause an immune response in some people. Considering that individuals make unique antibodies and not everyone reacts as severely, not all Celiac sufferers have a problem with dairy. Unfortunately, it seems that I do. I'm new to the the world of Celiac's, but I have a degree in chemistry, a minor in bio, and I'm in graduate school for medicinal chemistry. It helps being able to understand the molecular biology aspect. Lactose is a milk sugar that can be refined and, yes, separated from the protein portion of milk. Lactose intolerance is common among Celiac patients b/c of the damage to the small intestines, where the enzyme lactase is made. Some people, like my son, regain the ability to drink milk after going gluten-free. For me, lactose free/gluten-free dair still produced gluten-like symptoms, albeit milder than those from wheat.

So, in creative lay-man's terms:

Your antibodies are skeleton keys that match to gluten. If you are unlucky, then your key may also fit casein, but maybe not as well.

Not all casein is the same either. (cow, sheep, goat, etc) I haven't tried goat's milk or cheese yet, but plan to. I rather hope it's okay, b/c I'm very fond of dairy.

I hope this helps.

      Outgrow celiac?

      By Wheatwacked · Posted

      @Riley., Welcome to the forum.   It was once believed that Celiac Disease was only a childhood disease and it can be outgrown.  That was before 1951, before gluten was discovered to be cause of Celiac Disease, also called Infantilism.  Back then Cileac Disease was thought to be only a gastro intestinal disease, once you  "outgrew" the colicky phase, you were cured. You were so lucky to be diagnosed at 5 years old so your developing years were normal.  Gluten can affect multiple systems.  The nervous system, your intellegence. The muscules, skeleton. It can cause neurological issues like brain fog, anxiety, and peripheral neuropathy.  It can cause joint pain, muscle weakness, and skin rashes. Epilepsy is 1.8 times more prevalent in patients with celiac disease, compared to the general population. Because through malabsorption and food avoidances, it causes vitamin D and numerouus other essential nutrient deficiencies, it allows allergies, infections, poor growth, stuffy sinuses and eustacian tubes. There is even a catagory of celiac disease called "Silent Celiac".  Any symptoms are explained away as this, that or the other thing. Gluten is one of the most addictive substances we consume.  Activating the Opiod receptors in our cells, it can numb us to the damage that it, and other foods are causing.  It has become socially acceptable to eat foods that make us feel sick.  "There's a pill for that".   It is generally accepted that n fact you are weird if you don't. The hardest part is that if you don't eat gluten you will feel great and think why not.  But slowly it will effect you, you'll be diagnosed with real diseases that you don't have. You'll be more susseptable to other autoimmune diseases.  As you read through the posts here, notice how many are finally dianosed, after years of suffering at older ages.  Is it worth it? I think not. Perhaps this book will help:  Here is a list of possible symptoms:

      Outgrow celiac?

      Hi! Im Riley, 18 years old and have been diagnosed for 13 years.. the testing started bc I stopped growing and didn’t gain any weight and was really small and thin for my age.  I got diagnosed when I was 5 and have been living gluten free since, in elementary and middle school it was hard for me and I kept contaminating myself bc I wanted to fit in with my friends so so badly. I ate gluten secretly at school and mostly regretted it 30 minutes later.  I’ve had symptoms like diarrhea, nausea, headaches, stomachaches, threw up a lot and was really emotional.  In 2022 I really started working on myself and tried to stay gluten free and if I did eat gluten I wouldn’t tell anyone and suffer in silence.  Last year in July I begged my mom to let me „cheat“ one day bc I just wanted to fit in… I ate a lot of different stuff, all the stuff I missed out on in my childhood like nuggets, pizza and all that.. I didn’t have symptoms that day and was doing really fine My mom and I wanted to test how far we can go and said we would test it for 12 weeks to get my blood taken after to see if I’m doing good or if symptoms start showing  As a now 18 year old girl who finally gained a normal weight and doesn’t get symptoms I’m to scared to get tested/my blood taken cuz I finally found comfort in food and it got so much easier for me and my family.  A year and 4 months later i still didn’t get any symptoms and have been eating gluten daily.  I’m scared to get tested/my blood taken cuz what if I’m actually not fine and have to go back to eating gluten free. Any tips to get over that fear and „suck it up“ cuz I know I could seriously damage my body… sorry if I seem like a idiot here… just don’t really know what to do :,)

      There is much helpful 'truth' posted on this forum. Truths about Celiac Disease are based on scientific research and people's experience. Celiac disease is inherited. There are 2 main Celiac 'genes' but they are variations of one gene called HLa - DQ What is inherited when a person inherits one or both of the DQ2 or the DQ8 is a predisposition to develop celiac disease after exposure to a environmental trigger. These 2 versions of the DQ gene are useful in diagnosing  celiac disease but there are about 25 other genes that are known to influence celiac disease so this food intolerance is a multigenic autoimmune disease. So with so many genes involved and each person inheriting a different array of these other genes one person's symptoms may be different than another's symptoms.  so many of these other genes.  I don't think that much research on these other genes as yet. So first I wrote something that seem to tie together celiac disease and migraines.  Then you posted that you had migraines and since you went gluten free they only come back when you are glutened. Then Scott showed an article that reported no connection between migraines and celiac disease, Then Trents wrote that it was possible that celiacs had more migraines  and some believed there was a causal effect. You are each telling the truth as you know it or experienced it.

      Aldi Pueblo Lindo Yellow Corn Tortillas

      By tiffanygosci · Posted

      Another annoying thing about trying to figure this Celiac life out is reading all of the labels and considering every choice. I shop at Aldi every week and have been for years. I was just officially diagnosed Celiac a couple weeks ago this October after my endoscopy. I've been encouraged by my local Aldi in that they have a lot of gluten free products and clearly labeled foods. I usually buy Milagro corn tortillas because they are cheap and are certified. However, I bought a package of Aldi's Pueblo Lindo Yellow Corn Tortillas without looking too closely (I was assuming they were fine... assuming never gets us anywhere good lol) it doesn't list any wheat products and doesn't say it was processed in a facility with wheat. It has a label that it's lactose free (hello, what?? When has dairy ever been in a tortilla?) Just, ugh. If they can add that label then why can't they just say something is gluten free or not? I did eat some of the tortillas and didn't notice any symptoms but I'm just not sure if it's safe. So I'll probably have to let my family eat them and stick with Milagro. There is way too much uncertainty with this but I guess you just have to stick with the clearly labeled products? I am still learning!

      Thank you all for sharing your experiences! And I am very thankful for that Thanksgiving article, Scott! I will look into it more as I plan my little dinner to bring with on the Holiday I'm also glad a lot of research has been done for Celiac. There's still a lot to learn and discover. And everyone has different symptoms. For me, I get a bad headache right away after eating gluten. Reoccurring migraines and visual disturbances were actually what got my PCP to order a Celiac Panel. I'm glad he did! I feel like when the inflammation hits my body it targets my head, gut, and lower back. I'm still figuring things out but that's what I've noticed after eating gluten! I have been eating gluten-free for almost two months now and haven't had such severe symptoms. I ate a couple accidents along the way but I'm doing a lot better
