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.

    • Cross reactivity is a bit of a myth type thing, but we do get food sensitivities and intolerance issues that do creep up and they are always different for each person. A food diary and keeping track of what causes symptoms is what you need to do. Here is a true gluten avoidance list and a article on food sensitivities.

    • Me too. I still get transient lower back pain occasionally when my bladder or colon is full. It goes away immediately on voiding. Regardless of anything other diseases you may have, being wheat free gives you relief so even if not Celiac you are Non Celiac Wheat Sensitive. There are over 200 symptoms that are improved with GFD gluten free diet. Google it. It is an impressive list. In any case, while it is good to have a diagnosis, there is only one treatment, do not eat wheat and deal with the inevitable malnutrition damage.(think Biafra babies 1970.) Most will improve over time. Whatever doesn't improve should be investigated to be safe, but realize that recovery may take years. Wheat flour used should be limited to Paper Mache sculpture and library paste.  
    • Here is a partial list of what I no longer suffer from as a result of not eating wheat. Some like the sleep apnea and gerd and back pain and addiction to alcohol were almost immediate. The foot pain is improved to just numbness sometimes. My long term depression went away when I added vitamin D 10,000 iu a day for a year, but the improvement started almost immediately. Muscle tone and energy improved when I added iodine. one sheet sushi seaweed a day. My Fibromyalgia is controlled with 15 mg oral Prednisone a day. I remember as a kid waking up and having to pick the dried mucuos off the roof of my mouth. That is gone and for the first time in my life I am a nose breather. Drink lots of water to help with the mucous if it is thick. Some mornings mine is like rubber cement. I need to quit smoking now.  You can improve have faith, but healing takes time. Stay the course. A Romaine lettuce salad everyday helped the gut pain. Gerd shortness of breath sleep apnea back pain snoring prostrate hypertrophy contact lens protein buildup night vision improved cataracts reduced head hair growth foot pain sleeping no more than 2 hours at a stretch slow healing no energy. Pretty much bed ridden. 
    • Celiac Disease is damage to the nooks and crannies in our intestines leading to malnutrition, vitamin deficiencies with all the various symptoms that make it so hard to diagnose. Then you add years of the antacids, antibiotics, Tylenol, opioids, alcohol, etc., each with their own particular side effects and damage. Now you've got a toxic environment that kills off the beneficial bacteria increasing malnutrition. Theoretically you can eat anything except gluten. But wheat is so ubiquitous in our diet and economy there are unlimited opportunities for cross contamination. So read the label. Use common sense. If there isn't a label it doesn't have wheat so you can eat. Big Food likes to add wheat to everything because it is addictive and helps them ensure you can't eat just one. Why on earth else would Campbells Tomato Soup have wheat listed as an ingredient? Meantime your body is in distress from malnutrition so you need to be sure to replenish D3, and Iodine for starters and treat and support any other symptoms while you heal. Good nutrition without wheat is the only way to stop progression. And just like chewing paint chips made with lead is bad, so is food with wheat.   well said, doesn't need a label.
