    Celiac.com 05/15/2018 - There is a good amount of anecdotal evidence that people with non-celiac gluten sensitivity can tolerate sourdough bread, but there is no good science to support such claims. To determine if sourdough bread help conquer wheat sensitivity, the Alberta Wheat Commission (AWC) is funding a team of researchers to see if the sourdough fermentation process can reduce or eliminate wheat components that trigger wheat sensitivity.

    The project will study the way the sourdough bread fermentation process breaks down proteins and carbohydrates in wheat flour.

    Chair of the AWC Research Committee, Terry Young, said new research suggests that wheat protein may not be the cause of gluten sensitivity in people without celiac disease. Longer fermentation, aka sourdough fermentation, is more common in Europe. Young says that reports indicate that “incidents of non-celiac sensitivity…are actually lower in Europe." He adds the current research will focus on the fermentation, but the future may include the development of wheat varieties for gluten sensitive individuals.

    The research will be led by food microbiologist at the University of Alberta, Dr. Michael Gänzle, who said the use of sourdough bread in industrial baking reduces ingredient costs and can improve the quality of bread as well.

    Dr. Gänzle wants to assess anecdotal claims that people with non-celiac wheat or gluten intolerance can tolerate sourdough bread. His team wants to “determine whether fermentation reduces or eliminates individual wheat components that are known or suspected to cause adverse effects.”

    The team readily admits that their project will not create products that are safe for people with celiac disease. They may, however, create products that are useful for people without celiac disease, but who are gluten sensitivity.

    The AWC is collaboratively funding the project with the Saskatchewan Wheat Development Commission, and the Minnesota Wheat Research Promotion Council, which will contribute $57,250, and $20,000, respectively. The research team will issue a report of its findings after the project is completed in 2021.

    Studies like this are important to shed light on the differences between celiac and non-celiac gluten sensitivity. Stay tuned for more developments in this exciting area of research.

    I find it disturbing that wheat interest groups are funding this.  What will they do with the resulting data? I fear it will be skewed in favor of wheat promotion.

    Appl Environ Microbiol. 2004 Feb;70(2):1088-1096 Celiac.com 02/26/2004 - Please note that the sourdough bread used in this study is not your garden-variety sourdough bread, and as far as I know it is not commercially available. Even though this study had very promising results, it was conducted on a relatively small number of people, and larger studies need to be carried out before reaching any conclusions about the long-term safety of celiacs consuming this type of sourdough bread. -Scott Adams
    Researchers in Europe conducted a novel study which utilized a highly specialized sourdough lactobacilli containing peptidases that have the ability to hydrolyze Pro-rich peptides, including the 33-mer peptide, which is the main culprit in the immune response associated with celiac disease. The sourdough bread in the study was made from a dough mixture that contained 30% wheat flour and other nontoxic flours including oat, millet, and buckwheat, which was then started with the specialized lactobacilli. After 24 hours of fermentation all 33-mer peptides and low-molecular-mass, alcohol-soluble polypeptides were almost totally hydrolyzed.
    For the next step in the study the researchers extracted proteins fro the sourdough and used them to produce a "peptic-tryptic digest" for in vitro agglutination tests on human K 562 subclone cell. The agglutinating activity of the sourdough proteins was found to be 250 times higher that that of normal bakers-yeast or lactobacilli started breads.
    A double blind test was then conducted in which 17 celiac disease patients were given 2 grams of gluten-containing bread started with bakers yeast or lactobacilli. Thirteen of them showed distinct, negative changes in their intestinal permeability after eating the bread, and 4 of them did not show any negative effects. The specially prepared sourdough bread was then given to all 17 patients and none of them had intestinal permeability reactions that differed from their normal baseline values.
    The researchers conclude: "These results showed that a bread biotechnology that uses selected lactobacilli, nontoxic flours, and a long fermentation time is a novel tool for decreasing the level of gluten intolerance in humans."

    Celiac.com 04/19/2012 - A team of researchers examined the effect of corn, rice and amaranth gluten-free sourdoughs on the release of nitric oxide (NO) and synthesis of pro-inflammatory cytokines by duodenal mucosa biopsies of eight celiac disease patients.
    The research team included Maria Calasso, Olimpia Vincentini, Francesco Valitutti, Cristina Felli, Marco Gobbetti and Raffaella Di Cagno.
    The team used select lactic acid bacteria as starters for making corn, rice and amaranth sourdoughs. From these gluten-free sourdough matrices, they made chemically acidified doughs, without bacterial starters, and doughs started with baker’s yeast alone.
    They produced pepsin-trypsin (PT) digests from all sourdoughs and doughs, and used the results to the measure the recovery of biopsy specimens from eight celiac disease patients at diagnosis. They also measured the release of NO and the synthesis of pro-inflammatory cytokines interferon-γ (IFN-γ).
    They found that lactic acid bacteria acidified and grew well (ca. log 9.0 CFU/g) during fermentation, showing strong proteolysis on all gluten-free samples.
    They also found that duodenal biopsy specimens still released NO and IFN-γ when subjected to treatments with basal medium (control), PT-digest from chemically acidified doughs and PT-digest from doughs fermented with baker’s yeast alone.
    In fact, in every case, biopsy specimens treated with PT-digests from all gluten-free matrices with sourdough fermentation substantially reduced NO release and IFN-γ synthesis.
    From their results, the team concludes that sourdough fermentation might offer an easy and effective way to speed recovery from intestinal inflammation of celiac patients beginning a gluten-free diet.

    Celiac.com 12/28/2012 - Sourdough bread is made by a long fermentation of dough using naturally occurring yeasts and lactobacilli. Compared with regular breads, sourdough usually has a sour taste due to the lactic acid produced by the lactobacilli.
    Sourdough fermentation helps improve bread quality by prolonging shelf life, increasing loaf volume, delaying staling, as well as by improving bread flavor and nutritional properties.
    However, sourdough isn't just good for making better bread. Recent studies show that sourdough fermentation can also speed gut healing in people with celiac disease at the start of a gluten-free diet.
    Over the past few years researchers have been experimenting with sourdough fermentation as a means for making traditional wheat bread safe for people with celiac disease. Recently, yet another study examined the safety of this process with great results.
    "While the study was small, it did show that individuals with celiac disease who ate specially prepared sourdough wheat bread over the course of 60 days experienced no ill effects." Obviously, larger and more detailed studies need to be carried out, but the early results are intriguing.
    In the meantime, sourdough bread made with gluten-free flours might be the best way for people with celiac disease and gluten-sensitivity to get the benefits of sourdough cultures, and to enjoy fresh, minimally processed bread.
    Of course, not everyone can bake their own sourdough bread. That's why I was happy to learn that more artisanal bread bakers are turning to baking their own delicious gluten-free sourdough to share with others.
    One of these small, artisanal bread makers is a local San Francisco baker named Sadie Scheffer, who runs a company called BreadSRSLY. Sadie bakes delicious long-fermented sourdough bread and other products, using gluten-free grains. She delivers most of her products by bicycle.
    Having sampled Sadie's bread, and I can say that it is some of the best sourdough bread I've tasted, gluten-free or not. It isdelicious, dense, and chewy sourdough bread that is perfect for toasting. The loaves are fermented for twelve hours before baking. Folks in San Francisco can find Sadie's delicious gluten-free sourdough bread at BiRite, Gluten Free Grocery and Other Avenues, and at breadsrsly.com.
    Until science establishes the safety of wheat-based sourdough for people with celiac disease, I think that long-fermented sourdough bread, made with gluten-free flour, represents the future of gluten-free bread for people with celiac disease and gluten-sensitivity.
    Here's a recipe for gluten-free sourdough starter.

    Celiac.com 12/27/2012 - Making sourdough 'starter' is the first step in the traditional fermentation process for sourdough bread. You begin the process by “growing” strains of lactobacillus bacteria and yeast together in what bakers call the 'starter.' When the 'starter' is added to flour, the organisms produce enzymes that break down the gluten protein in the flour in a process called 'hydrolysis.' Hydrolysis is the breakdown of larger particles into smaller ones, specifically amino acids.
    Some studies show that these amino acids are no longer toxic to individuals who are sensitive to gluten. Basically, these cultures partially digest the wheat or other grains; doing part of the stomach's job in advance part of the digestive process.
    When you add the gut healing benefits of lactobacillus, the result is bread that acts like medicine; delicious medicine, at that.
    Using sourdough starter to bake breads using gluten-free grains is an excellent way for people with celiac disease and gluten-intolerance to get the benefits of sourdough cultures and to enjoy delicious fresh bread.
    Here's a recipe for gluten-free sourdough starter that you can use to bake countless loaves of delicious gluten-free bread:
    Gluten-free Sourdough Starter
    Ingredients:
    1 cup water, 110 to 115 deg F
    2 1/4 teaspoons active dry yeast
    1 1/2 cups rice flour 
    Directions:
    Combine all ingredients in a 1-quart container. It will be thick.
    Cover loosely with plastic wrap or foil and let stand for one to three days in a warm place, stirring 2 or 3 times daily.
    The starter will rise and fall during the fermentation process.When it is ready to use, it will be bubbly and may have a layer of hooch, or liquid, on top of the starter, which can be stirred back in.
    Use the starter right away, or put it in refrigerator.
    You can easily replenish your starter by keeping at least one cup of finished aside. Add 1 cup water and 1 1/2 cup white rice flour. Cover loosely and let stand in a warm place for 12 hours, stirring once or twice. Use what you need, and refrigerate the rest. Replenish as needed.

    Can a Gluten-Free Diet Normalize Vitamin D Levels for Celiac Patients?
    Celiac.com 08/16/2018 - What is the significance of vitamin D serum levels in adult celiac patients? A pair of researchers recently set out to assess the value and significance of 25(OH) and 1,25(OH) vitamin D serum levels in adult celiac patients through a comprehensive review of medical literature.
    Researchers included F Zingone and C Ciacci are affiliated with the Gastroenterology Unit, Department of Surgery, Oncology and Gastroenterology, University of Padua, Padua, Italy; and the Celiac Center, AOU San Giovanni di Dio e Ruggi di Aragona, University of Salerno, Department of Medicine and Surgery, Salerno, Italy. 
    Within the wide spectrum of symptoms and alteration of systems that characterizes celiac disease, several studies indicate a low-level of vitamin D, therefore recent guidelines suggest its evaluation at the time of diagnosis. This review examines the data from existing studies in which vitamin D has been assessed in celiac patients. 
    Our review indicates that most of the studies on vitamin D in adult celiac disease report a 25 (OH) vitamin D deficiency at diagnosis that disappears when the patient goes on a gluten-free diet, independently of any supplementation. Instead, the researchers found that levels of calcitriol, the active 1,25 (OH) form of vitamin D, fell within the normal range at the time of celiac diagnosis. 
    Basically, their study strongly suggests that people with celiac disease can recover normal vitamin D levels through a gluten-free diet, without requiring any supplementation.

    Could Gluten-Free Food Be Hurting Your Dog?
    Celiac.com 08/15/2018 - Grain-free food has been linked to heart disease in dogs. A canine cardiovascular disease that has historically been seen in just a few breeds is becoming more common in other breeds, and one possible culprit is grain-free dog food. 
    The disease in question is called canine dilated cardiomyopathy (DCM), and often results in congestive heart failure. DCM is historically common in large dogs such as Great Danes, Newfoundlands, Irish Wolfhounds, Saint Bernards and Doberman Pinschers, though it is also affects some Cocker Spaniels.  Numerous cases of DCM have been reported in smaller dogs, whose primary source of nutrition was food containing peas, lentils, other legume seeds or potatoes as main ingredients. These reported atypical DCM cases included Golden and Labrador Retrievers, a Whippet, a Shih Tzu, a Bulldog and Miniature Schnauzers, as well as mixed breeds. 
    As a result, the U.S. Food and Drug Administration's Center for Veterinary Medicine, along with a group of veterinary diagnostic laboratories, is investigating the possible link between DCM and pet foods containing seeds or potatoes as main ingredients. The good news is that in cases where the dog suffers no genetic component, and the disease is caught early, simple veterinary treatment and dietary change may improve heart function.
    According to Nutritional Outlook, an industry publication for makers of dietary supplements and healthy foods and beverages, there is a growing market for “free from” foods for dogs, especially gluten-free and grain-free formulations. In 2017, about one in five dog foods launched was gluten-free. So, do dogs really need to eat grain-free or gluten-free food? Probably not, according to PetMD, which notes that many pet owners are simply projecting their own food biases when choosing dog food.
    Genetically, dogs are well adapted to easily digest grains and other carbohydrates. Also, beef and dairy remain the most common allergens for dogs, so even dogs with allergies are unlikely to need to need grain-free food. 
    So, the take away here seems to be that most dogs don’t need grain-free or gluten-free food, and that it might actually be bad for the dog, not good, as the owner might imagine.
    Stay tuned for more on the FDA’s investigation and any findings they make.

    Did You Miss the Gluten-Free Fireworks This Past Fourth of July?
    Celiac.com 08/14/2018 - Occasionally, Celiac.com learns of an amusing gluten-free story after the fact. Such is the case of the “Gluten-Free Fireworks.” 
    We recently learned about a funny little event that happened leading up to Fourth of July celebrations in the town of Springdale in Northwest Arkansas. It seems that a sign advertising "Gluten Free Fireworks" popped up near a fireworks stand on interstate 49 in Springdale. 
    In case you missed the recent dose of Fourth of July humor, in an effort to attract customers and provide a bit of holiday levity, Pinnacle Fireworks put up a sign advertising "gluten-free fireworks.” 
    The small company is owned by Adam Keeley and his father. "A lot of the people that come in want to crack a joke right along with you," Keeley said. "Every now and then, you will get someone that comes in and says so fireworks are supposed to be gluten-free right? Have I been buying fireworks that have gluten? So then I say no, no they are gluten-free. It's just a little fun."
    Keeley said that their stand saw a steady flow of customers in the week leading up to the Fourth. In addition to selling “gluten-free” fireworks, each fireworks package sold by Pinnacle features a QR code. The code can be scanned with a smartphone. The link leads to a video showing what the fireworks look like.
    We at Celiac.com hope you and your family had a safe, enjoyable, and, yes, gluten-free Fourth of July. Stay tuned for more on gluten-free fireworks and other zany, tongue-in-cheek stories.

    Stress-Related Disorders Associated with Higher Risk for Autoimmune Disease
    Celiac.com 08/13/2018 - It’s not uncommon for people to have psychiatric reactions to stressful life events, and these reactions may trigger some immune dysfunction. Researchers don’t yet know whether such reactions increase overall risk of autoimmune disease.
    Are psychiatric reactions induced by trauma or other life stressors associated with subsequent risk of autoimmune disease? Are stress-related disorders significantly associated with risk of subsequent autoimmune disease?
    A team of researchers recently set out to determine whether there is an association between stress-related disorders and subsequent autoimmune disease. The research team included Huan Song, MD, PhD; Fang Fang, MD, PhD; Gunnar Tomasson, MD, PhD; Filip K. Arnberg, PhD; David Mataix-Cols, PhD; Lorena Fernández de la Cruz, PhD; Catarina Almqvist, MD, PhD; Katja Fall, MD, PhD; Unnur A. Valdimarsdóttir, PhD.
    They are variously affiliated with the Center of Public Health Sciences, Faculty of Medicine, University of Iceland, Reykjavík, Iceland; the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden; the Department of Epidemiology and Biostatistics, Faculty of Medicine, University of Iceland, Reykjavík, Iceland; the Department of Rheumatology, University Hospital, Reykjavík, Iceland; the Centre for Rheumatology Research, University Hospital, Reykjavík, Iceland; the National Centre for Disaster Psychiatry, Department of Neuroscience, Psychiatry, Uppsala University, Uppsala, Sweden; the Stress Research Institute, Stockholm University, Stockholm, Sweden; the Centre for Psychiatry Research, Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden; the Stockholm Health Care Services, Stockholm County Council, Stockholm, Sweden; the Astrid Lindgren Children’s Hospital, Karolinska University Hospital, Stockholm, Sweden; the Clinical Epidemiology and Biostatistics, School of Medical Sciences, Örebro University, Örebro, Sweden; the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden; and the Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts.
    The team conducted a Swedish register-based retrospective cohort study that included 106, 464 patients with stress-related disorders, 1,064 ,640 matched unexposed individuals, and 126 ,652 full siblings to determine whether a clinical diagnosis of stress-related disorders was significantly associated with an increased risk of autoimmune disease.
    The team identified stress-related disorder and autoimmune diseases using the National Patient Register. They used Cox model to estimate hazard ratios (HRs) with 95% CIs of 41 autoimmune diseases beyond 1 year after the diagnosis of stress-related disorders, controlling for multiple risk factors.
    The data showed that being diagnosed with a stress-related disorder, such as post-traumatic stress disorder, acute stress reaction, adjustment disorder, and other stress reactions, was significantly associated with an increased risk of autoimmune disease, compared with matched unexposed individuals. The team is calling for further studies to better understand the associations and the underlying factors.
