I am just curious. As a scientist (and I am not trying to be rude), how can you determine if hydrologized wheat protein from your husband’s shampoo was actually the culprit? If I recall at your diagnosis, you were seronegative, Marsh Stage I, gene positive, but your doctor still suspected celiac disease. You improved on a gluten diet. Other than observation, how do you really know? Could it not be something else that triggered your symptoms?
I firmly believe that even trace amounts of gluten (under 20 ppm), can impact sensitive celiacs. But traces of a protein within a shampoo from someone else’s hair that was rinsed?
I also can't have dairy but through a series of experiments and a lot of research I think I've pinpointed my problem. It may or may not be the same for you, but I thought I'd share.
There are two kinds of beta-casein protein A1 and A2. We'll call A1 "bad casein" and A2 "good casein". The two proteins differ only in a single amino acid, but this is enough to make it so that they are processed differently in your guy. Bad casein is actually broken down into a casomorphin, which is an opioid peptide. That does not mean that milk gets you high, or is as addictive as heroin, or anything like that, it just means that it can interact with opioid receptors (which the gut has a bunch of).
It's worth noting that opioids cause constipation due to their interaction with the opioid receptors in the gut, and that a lot of people feel like cheese and dairy slow things down, but any connection between the two is pure speculation on my part at this point.
Now here's where things get weird. The vast majority of milk cows in the western world are derived from Holstein-like breeds, meaning black and white cows. In a few select places, you'll see farms that use Jersey-type cows, or brown cows (Jersey cows produce less milk than Holsteins, but many connoisseurs feel it's a higher quality milk, particularly for cheese). Holstein-like cows have A1 and A2 casein (bad and good), however, Jersey-type cows only have A2 (good casein), unless their genetic line involved a Holstein somewhere in the past, which does happen.
A company in New Zealand figured out how to test their cows for these two genes, and selected their herd down to cows that specifically produce ONLY A2 (good) casein. You might have seen it in the store, it's called A2 milk. Some people have had a lot of luck with this milk, though it still doesn't solve the problem of cheese.
I have suspected, due to trial and error and a few accidental exposures, that I have a problem with A1 casein, but not A2. In line with this: I am able to eat sheep and goat dairy without any difficulty, so at least I can still enjoy those cheeses! I am also fortunate because I'm apparently not too sensitive, as I can still eat cow-milk butter. The process of making butter removes *most* (read: enough for me) of the casein.
However, if I eat cow cheese or a baked good with milk, I get really sick. It's a much faster reaction than if I get glutened. Within minutes I'm dizzy and tired and my limbs are heavy. I have to sleep for a couple of hours, and then, over the next couple of days, I'm vulnerable to moodiness and muscles spasms and stomach upset just as though I'd been glutened (though the brain fog isn't as bad).
I actually haven't tried A2 milk yet, mostly due to lack of availability (and motivation, I don't miss milk, I miss CHEESE). However, last year, when I was getting ready to go on a trip to Italy, I had a thought. Once, in the recent past, when I'd been testing dairy, I'd had a slice of parmesan cheese. Miracle of miracles, I was fine. I didn't feel a thing! I was so excited that I ran out and got some brie to eat as a snack. That did not go so well...
Turns out parmigiano reggiano is made from the milk of the Reggiana variety of cow which is, you guessed it, a brown cow (they say red). I did a little more research and found that dairies in Italy predominantly use brown cows. So I decided to try something.
As some of you may know, Italy is something of a haven for celiacs. It's one of the most gluten-free friendly places I've ever been. You can say "senza glutine" in the smallest little town and they don't even bat their eyelashes. You can buy gluten free foods in the pharmacy because they're considered a MEDICAL NECESSITY. If travelling-while-celiac freaks you out, go to Italy. Check out the website for the AIC (Italy's Celiac society), find some accredited restaurants, and GO NUTS.
While I was there, I decided to see if I could eat the dairy. I could.
Friends, I ate gelato Every. Single. Night. after that. It was amazing. Between the dairy being safe for me and the preponderance of gluten free options, it was almost like I didn't have dietary restrictions. It was heaven. I want to go back and never leave.
So that's my story. Almost too crazy to believe.
TL;DR: Black and white cows make me sick, brown cows are my friends.
I'm a scientist, and I did a little research into the study. Looks valid and it was published in a respected journal.
The science looks solid. As someone who didn't have a super clean cut diagnosis before going gluten free, I'd love to see something like this become available.
Then again, there's no doubt in my mind that I can't have gluten, so any additional testing would be purely academic. But like I said, I'm a scientist. I can't help myself.
Update: I have tried calling the company several times and have emailed twice. I have yet to talk to a person on the phone and no one has emailed me back.
I did a little research and they were are already involved with a class action lawsuit about being labeled as salt free and one of the first ingredients is sodium chloride.
I am done with this shampoo because this whole company seems a little shady now!
I've actually been glutened by shampoo with hydrolyzed wheat protein, and I wasn't even the one using it. It was my husbands!
I swear I don't go around eating my husbands hair.
I am pretty sensitive though, so it's entirely believable that the trace amounts in his hair were getting onto his and my hands and then making its way to my mouth, etc. etc.
It was a slow and steady low grade glutening that eventually built up to something that I was able to recognize as more definitively "a glutening". Once we ditched the shampoo and I recovered, I realized that I'd been feeling it for weeks.
It's going to depend on your level of sensitivity, but even if you don't feel it, it could still be doing damage.
I second that. Starch is a carbohydrate, protein is a protein (obviously), there is no simple process that would convert one into the other. Also, as gluten is a protein, converting starch to protein wouldn't be expected to do anything to gluten ANYWAY.
Speaking as a biologist here. I call poppycock.
