Experts See Way To Cut Wheat Gluten

Scott,

Maybe you have the full story and I missed it. Our paper didnt have too much to say----

Experts see way to cut wheat gluten [Honolulu Star-Advertiser, 4 December 2012]

A team of scientists has concluded that it is possible to develop gluten-free wheat plants, according to a study published in the journal PNAS, the Proceedings of the National Academy of Sciences.

People with serious gluten allergies such as celiac disease now have only one tried-and-true option and that is to swear off all foods containing wheat, barley and rye. Only then can they avoid the damage that gluten exposure wreaks, such as abdominal pain, nutritional deficiencies and a progressive flattening of the tiny hairlike villi in the gut that are needed for the proper digestion of food.

Avoiding gluten isn’t easy, and those with the discipline to succeed deal with a host of diet restrictions.

Gluten is a complicated mix of proteins that are stored in seeds of wheat, barley and rye, and only some of these proteins trigger the allergic reactions.

Scientists have experimented with sifting through varieties of wheat and barley lines that lack or make a lot less of key gluten proteins in their grains.

But though they have found varieties that lack some of the important allergenic proteins, “None of the tested materials was completely nontoxic for celiac patients and thus could not be recommended for general consumption,” note the study’s authors.

Those authors, Shanshan Wen of Washington State University in Pullman and colleagues, tried a different approach. It hinged on a key enzyme, one that helps activate a whole set of genes that make the most problematic gluten proteins. Using a genetic engineering trick, they knocked out that enzyme. As a result, the seeds of the wheat they studied had sharply reduced levels of this set of problem proteins.

The authors say it will take more tinkering before they can create a line that eliminates the problem proteins entirely while keeping other non-problem ones in the seeds. But they write that they have a good chance of doing it and that the resulting wheat still should make decent bread for baking.

Next will come testing — in cell cultures, mice and gluten-sensitive apes.

This isn’t the only approach to new dietary solutions for celiac disease. Some scientists, for example, think it might be possible to develop oral enzyme therapies. These would digest away the bits of gluten that cause allergic reactions because they aren’t properly digested by natural digestive enzymes.

Others think it might be possible to desensitize celiac patients by feeding them tiny amounts of gluten and slowly increasing the dose, an approach that’s been successful in some clinical trials in treating allergies to peanuts or milk.

I would've title it "Misguided dreamers see way to reduce one type of harmful protein sequence as academic/scientific exercise while admitting "None of the tested materials was completely nontoxic for celiac patients"."

Personally, I find the idea on par w/ the last graf's "desensitizing" celiac away, as if it's an allergy, which should, imho, be a ridiculous notion.

We need to stop them from putting this GMO garbage "modified sorta kinda like don't look too closely not toxic to celiacs gluten" wheat genetic material into RICE, to create what they pretend is a safe, drought - tolerant version of it. Talk about nightmare scenarios, and that is certainly where this could be heading, because of the vicious fight they waged against GMO labeling in California during the last election, a rice growing state. I am certainly amazed at the deliberate, ongoing, organized misinformation campaign against gluten free food safety the usual Forces of Evil are waging in the social media over this.

Well said Takala, Hell I blame gmo and the additives for our diseases and my food allergies, including celiac.

Genetic manipulation is - IMO - what has caused the alarming increase in Celiac Disease, NCGI along with all AIs -- I don't want a safe wheat - I want safe foods - period.

SO true Lisa-- just real food would be nice..

      Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy: and this recent study recommends 4-6 slices of wheat bread per day:

      Yes, you are right. Indeed, I’ve been feeling anemic since the beginning of this week, and today I felt horrible during a lecture at the university, I was trembling a lot and felt all my body incredibly heavy, so I had to come back home. I’ll do a blood test tomorrow, but I’m just worried about the possibility of it coming back negative. I’ve been eating two cookies in the morning as my only source of gluten over the past two weeks—could that affect the final result?

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.
