    Gastroenterology. 2005 Feb;128(2):393-401.
    Celiac.com 02/09/2005 – Norwegian scientists have been mapping gluten T-cell epitopes in various wheat ancestors and have found several varieties that may be suitable for those with celiac disease. The trigger for celiac disease has been identified as the epitopes that cluster within a stable 33mer fragment of wheat chromosome 6D. The scientists extracted and screened gluten from a variety of modern wheat ancestors to look for any T-cell stimulatory gluten peptides. They found that the 33mer fragment is encoded by alpha-gliadin genes on wheat chromosome 6D, which does not exist in the gluten of diploid einkorn or in certain types of tetraploid pasta wheat.
    These findings indicate that there may be grains that have long since been considered unsafe for those with celiac disease, but which may actually be safe and not contain any harmful gluten proteins. The most encouraging thing about this research is that baking and pasta-quality wheat ancestors could one day be added to our Safe List, which would greatly increase the quality of gluten-free products.
    Note: We strongly advise against celiacs including these grains in their diet until more testing and research is done to verify their safety.

    Celiac.com 12/19/2012 - Can scientists create gluten-free wheat strains that are safe for people with celiac disease, and suitable for making bread? According to a team of researchers writing in the journal PNAS, the answer is 'yes.'
    Gluten is a complex mix of proteins stored in kernels of wheat, barley and rye. Some, but not all, of these proteins trigger the immune reactions seen in celiac disease and gluten sensitivity.
    Scientists have already experimented with another method that involves sifting through various kinds of wheat and barley in search of types that contain little or no offensive gluten proteins in their grains.
    So far, researchers have found wheat varieties that lack some of the important allergenic proteins, but they have yet to find a variety that is completely safe for people with celiac disease.
    That fact led the research team led by Shanshan Wen of Washington State University in Pullman and colleagues, to try a new approach that focused on a key enzyme that helps to trigger a group of genes that produce the most reactive gluten proteins.
    To do this, they used a genetic engineering trick that eliminated the key enzyme altogether. The resulting seeds wheat kernels showed sharply lower levels of these reactive gluten proteins.
    The research team predicts that, with more more tinkering, they will be able to create a line of wheat that completely eliminates the problem proteins, and keeps the non-problem proteins in the wheat.
    According to their write-up, they feel that they have good odds of creating wheat that is safe for people with celiac disease, and suitable for producing good bread and baked goods.
    If successful, they will then begin testing the results in cell cultures, mice and gluten-sensitive apes.

    Celiac.com 06/05/2013 - In the west, sorghum has traditionally been used to feed livestock. However, in Africa and India, it has long been used to feed people.
    Recently, U.S. farmers have begun producing sorghum hybrids that are white in color, known as "food-grade" sorghum. In an effort to determine if these new hybrids are safe for people with celiac disease, a team of researchers set out to make a detailed molecular study.
    The team included Paola Pontieri, Gianfranco Mamone, Salvatore De Caro, Mitch R. Tuinstra, Earl Roemer, Josephine Okot, Pasquale De Vita, Donatella B. M. Ficco, Pietro Alifano, Domenico Pignone, Domenica R. Massardo, and Luigi Del Giudice.
    They are variously affiliated with the Istituto di Genetica Vegetale (IGV), CNR−Portici, c/o Dipartimento di Biologia, Sezione di Igiene, Napoli 80134, Italy, the Istituto di Genetica e Biofisica “Adriano Buzzati-Traverso” (IGB-ABT), CNR, in Napoli, Italy, the Istituto di Scienze dell’Alimentazione (ISA), CNR, in Avellino, Italy, with the Consiglio per la Ricerca e la sperimentazione in Agricoltura, Centro di Ricerca per la Cerealicoltura (CRA-CER) in Foggia, Italy, the Dipartimento di Scienze e Tecnologie Biologiche e Ambientali at the Università degli Studi di Lecce, Italy, and the Istituto di Genetica Vegetale, CNR, in Bari, Italy, with the Department of Agronomy at Purdue University in West Lafayette, Indiana, the Nu Life Market in Healy, Kansas in the United States, with Victoria Seeds Ltd. in Kampala, Uganda.
    Their study, which includes molecular evidence that sorghum lacks the proteins toxic to people with celiac disease, appears in ACS' Journal of Agricultural and Food Chemistry.
    Paola Pontieri and colleagues explain that those gluten proteins, present in wheat and barley, trigger an immune reaction in people with celiac disease that can cause abdominal pain and discomfort, constipation, diarrhea and other symptoms.
    This strong new biochemical evidence shows that these sorghum hybrids are safe for people with celiac disease.
    The researchers describe evidence from an analysis of the recently published sorghum genome, the complete set of genes in the plant, and other sources, that verify the absence of gluten proteins. They also note that sorghum has provides high nutritional value.
    Their report concludes that "[f]ood-grade sorghums should be considered as an important option for all people, especially celiac patients."
    The authors acknowledge funding from the Regione Campania, the Istituto Banco di Napoli -- Fondazione and the Compagnia di San Paolo.

    Celiac.com 11/11/2014 - There have been claims that certain strains of wheat, especially ancient strains, such as einkorn, do not trigger adverse reactions in people with celiac disease, or that they trigger less severe reactions.
    Until now, researchers haven't been able to say for certain that celiac disease patients react adversely to all varieties of wheat, or whether there may be differences in reactions to certain strains.
    A research team recently evaluated the safety of ancient strains of wheat in celiac disease. The researchers included Tanja Šuligojemailemail, Armando Gregorinidemail, Mariastella Colombaeemail, H. Julia Elliscemail, and Paul J. Ciclitirac
    To get a better idea of the nature of celiac factions to wheat, the team studied seven Triticum accessions showing different origin (ancient/modern) and ploidy (di-, tetra- hexaploid).
    In all, they tested ancient Triticum monococcum precoce (AA genome) and Triticum speltoides (BB genome), accessions of Triticum turgidum durum (AABB genome) including two ancient (Graziella Ra and Kamut) and two modern (Senatore Cappelli and Svevo) durum strains of wheat and Triticum aestivum compactum (AABBDD genome).
    They evaluated small intestinal gluten-specific T-cell lines generated from 13 celiac patients with wheat accessions by proliferation assays. They found that all strains of wheat they tested triggered a range of adverse responses, independent of ploidy or ancient/modern origin.
    Based on these results, they suggest that all strains of wheat, even ancient strains previously suggested to be low or devoid of celiac toxicity, should be tested for immunogenicity using gluten-specific T-cell lines from multiple celiac patients rather than gluten-specific clones to assess their potential toxicity.
    They also emphasize the need for celiac patients to follow a strict gluten-free diet, including avoidance of ancient strains of wheat.

    Celiac.com 05/21/2018 - Just a year ago, Starbucks debuted their Canadian bacon, egg and cheddar cheese gluten-free sandwich. During that year, the company basked in praise from customers with celiac disease and gluten-sensitivity for their commitment to delivering a safe gluten-free alternative to it’s standard breakfast offerings.
    But that commitment came to an ignoble end recently as Starbucks admitted that their gluten-free sandwich was plagued by  “low sales,” and was simply not sustainable from a company perspective. The sandwich may not have sold well, but it was much-loved by those who came to rely on it.
    With the end of that sandwich came the complaints. Customers on social media were anything but quiet, as seen in numerous posts, tweets and comments pointing out the callous and tone-deaf nature of the announcement which took place in the middle of national Celiac Disease Awareness Month. More than a few posts threatened to dump Starbucks altogether.
    A few of the choice tweets include the following:  
    “If I’m going to get coffee and can’t eat anything might as well be DD. #celiac so your eggbites won’t work for me,” tweeted @NotPerryMason. “They’re discontinuing my @Starbucks gluten-free sandwich which is super sad, but will save me money because I won’t have a reason to go to Starbucks and drop $50 a week,” tweeted @nwillard229. Starbucks is not giving up on gluten-free entirely, though. The company will still offer several items for customers who prefer gluten-free foods, including Sous Vide Egg Bites, a Marshmallow Dream Bar and Siggi’s yogurt.
    Stay tuned to learn more about Starbucks gluten-free foods going forward.

    Celiac.com 05/18/2018 - Across the country, colleges and universities are rethinking the way they provide food services for students with food allergies and food intolerance. In some cases, that means major renovations. In other cases, it means creating completely new dining and food halls. To document both their commitment and execution of gluten-free and allergen-free dining, these new food halls are frequently turning to auditing and accreditation firms, such as Kitchens with Confidence.
    The latest major player to make the leap to allergen-free dining is Syracuse University. The university’s Food Services recently earned an official gluten-free certification from Kitchens with Confidence for four of the University’s dining centers, with the fifth soon to follow.
    To earn the gluten-free certification from Kitchens with Confidence, food services must pass a 41 point audit process that includes 200 control check points. The food service must also agree to get any new food item approved in advance, and to submit to monthly testing of prep surfaces, to furnish quarterly reports, and to provide information on any staffing changes, recalls or incident reports. Kitchens with Confidence representatives also conduct annual inspections of each dining center.
    Syracuse students and guests eating at Ernie Davis, Shaw, Graham and Sadler dining centers can now choose safe, reliable gluten-free food from a certified gluten-free food center. The fifth dining center, Brockway, is currently undergoing renovations scheduled for completion by fall, when Brockway will also receive its certification.
    Syracuse Food Services has offered a gluten-free foods in its dining centers for years. According to Jamie Cyr, director of Auxiliary Services, the university believes that the independent Gluten-Free Certification from Kitchens with Confidence will help ease the anxiety for parents and students.”
    Syracuse is understandably proud of their accomplishment. According to Mark Tewksbury, director of residence dining operations, “campus dining centers serve 11,000 meals per day and our food is made fresh daily. Making sure that it is nutritious, delicious and safe for all students is a top priority.”
    Look for more colleges and universities to follow in the footsteps of Syracuse and others that have made safe, reliable food available for their students with food allergies or sensitivities.

    Celiac.com 05/17/2018 - Celiac disease is not one of the most deadly diseases out there, but it can put you through a lot of misery. Also known as coeliac, celiac disease is an inherited immune disorder. What happens is that your body’s immune system overreacts to gluten and damages the small intestine. People who suffer from the disease cannot digest gluten, a protein found in grain such as rye, barley, and wheat. 
    While it may not sound like a severe complication at first, coeliac can be unpleasant to deal with. What’s worse is it would lower your body’s capacity to absorb minerals and vitamins. Naturally, the condition would cause nutritional deficiencies. The key problem that diagnosing celiac is difficult and takes take longer than usual. Surprisingly, the condition has over 200 identified symptoms.
    More than three million people suffer from the coeliac disease in the United States alone. Even though diagnosis is complicated, there are symptoms that can help you identify the condition during the early stages to minimize the damage. 
    Here is how you can recognize the main symptoms of celiac disease:
    Diarrhea
    In various studies conducted over years, the most prominent symptom of celiac disease is chronic diarrhea.
    People suffering from the condition would experience loose watery stools that can last for up to four weeks after they stop taking gluten. Diarrhea can also be a symptom of food poisoning and other conditions, which is why it makes it difficult to diagnose coeliac. In certain cases, celiac disease can take up to four years to establish a sound diagnosis.
    Vomiting
    Another prominent symptom is vomiting.  
    When accompanied by diarrhea, vomiting can be a painful experience that would leave you exhausted. It also results in malnutrition and the patient experiences weight loss (not in a good way though). If you experience uncontrolled vomiting, report the matter to a physician to manage the condition.
    Bloating
    Since coeliac disease damages the small intestine, bloating is another common system. This is due to inflammation of the digestive tract. In a study with more than a 1,000 participants, almost 73% of the people reported bloating after ingesting gluten. 
    Bloating can be managed by eliminating gluten from the diet which is why a gluten-free diet is necessary for people suffering from celiac disease.
    Fatigue
    Constant feeling of tiredness and low energy levels is another common symptom associated with celiac disease. If you experience a lack of energy after in taking gluten, then you need to consult a physician to diagnose the condition. Now fatigue can also result from inefficient thyroid function, infections, and depression (a symptom of the coeliac disease). However, almost 51% of celiac patients suffer from fatigue in a study.
    Itchy Rash
    Now the chances of getting a rash after eating gluten are slim, but the symptom has been associated with celiac disease in the past. The condition can cause dermatitis herpetiformis, which causes a blistering skin rash that occurs around the buttocks, knees, and elbows. 
    A study found out that almost 17% of patients suffering from celiac disease might develop dermatitis herpetiformis due to lack of right treatment. Make sure you schedule an online appointment with your dermatologist or visit the nearest healthcare facility to prevent worsening of symptoms.
    Even with such common symptoms, diagnosing the condition is imperative for a quick recovery and to mitigate the long-term risks associated with celiac disease.

    Celiac.com 05/16/2018 - Galectins are a family of animal lectins marked by their affinity for N-acetyllactosamine-enriched glycoconjugates. Galectins control several immune cell processes and influence both innate and adaptive immune responses. A team of researchers recently set out to assess the role of galectins, particularly galectin-1 (Gal-1), in the treatment of celiac disease.
    The research team included Victoria Sundblad, Amado A. Quintar, Luciano G. Morosi, Sonia I. Niveloni, Ana Cabanne, Edgardo Smecuol, Eduardo Mauriño, Karina V. Mariño, Julio C. Bai, Cristina A. Maldonado, and Gabriel A. Rabinovich.
    The researchers examined the role of galectins in intestinal inflammation, particularly in Crohn’s disease, ulcerative colitis, and celiac disease patients, as well as in murine models resembling these inflammatory conditions. 
    Maintaining the fine balance between host immunity and tolerance promotes gut homeostasis, and helps to prevent inflammation. To gain insight into the role of Gal-1 in celiac patients, the team demonstrated an increase in Gal-1 expression following a gluten-free diet along with an increase in the frequency of Foxp3+ cells. 
    The resolution of the inflammatory response may promote the recovery process, leading to a reversal of gut damage and a regeneration of villi. Among other things, the team’s findings support the use of Gal-1 agonists to treat severe mucosal inflammation. In addition, Gal-1 may serve as a potential biomarker to follow the progression of celiac disease treatment.
    Gut inflammation may be governed by a coordinated network of galectins and their glycosylated ligands, triggering either anti-inflammatory or pro-inflammatory responses. That network may influence the interplay between intestinal epithelial cells and the highly specialized gut immune system in physiologic and pathologic settings.
    The team’s results demonstrate that the anti-inflammatory and tolerogenic response associated with gluten-free diet in celiac patients is matched by a substantial up-regulation of Gal-1. This suggests a major role of this lectin in favoring resolution of inflammation and restoration of mucosal homeostasis. 
    This data highlights the regulated expression of galectin-1 (Gal-1), a proto-type member of the galectin family, during intestinal inflammation in untreated and treated celiac patients. Further study of this area could lead to better understanding of the mechanisms behind celiac disease, and potentially to a treatment of the disease.
