    Celiac.com 09/29/2004 - Those lightweight, polystyrene containers that some restaurants give you for carrying home leftovers or take-out meals are known in the foodservice industry as clamshells. Their hinged-lid construction indeed resembles the architecture nature uses for clams, oysters, and other familiar bivalves.

    Every year, billions of these clamshells and other foodservice containers made from petroleum-based foams end up in already overstuffed landfills. Slow to decompose, they become yet another environmental burden.

    But the containers, along with other disposable foodservice items such as plates, bowls, and cups, can also be manufactured with biodegradable ingredients.

    ARS plant physiologist Gregory M. Glenn is working with EarthShell Corp., the California-based innovators of potato-starch-based foam products such as burger boxes, to create environmentally friendly disposables made with starch from wheat, the worlds most widely planted grain. His wheat-starch-based prototypes are sturdy, attractive, convenient to use, and just as leakproof as their polystyrene counterparts. Glenn is with the Bioproduct Chemistry and Engineering Research Unit at ARSs Western Regional Research Center in Albany, California.

    Why use wheat starch in packaging? Because it offers manufacturers of foodservice products another choice among starches when theyre buying raw materials. That purchasing flexibility can help keep their prices competitive with the polystyrene products. Another important cost savings: The machinery already used to make EarthShells potato-starch-based containers is suitable for the wheat-starch products as well. That sidesteps the need for costly retooling at manufacturing plants.

    The machines are presses or molds that work something like giant waffle irons, explains Glenn. First, a wheat-starch batter is poured onto the heated mold, which is then closed and locked. Moisture in the batter generates steam that, in turn, causes the batter to foam, expand, and fill the mold. The steam is vented and, when the baking is finished, the mold is opened, the product is removed, and the cycle starts again. This whole process takes less than a minute.

    A water-resistant coating, added later, helps the container keep its strength and shape when its filled with a hot, juicy cheeseburger or creamy pasta alfredo leftovers, for example. But once the container hits the backyard compost pile or municipal landfill, it biodegrades in only a few weeks.

    Perhaps having our ready-to-eat meal packed for us in a guilt-free throwaway container, such as a wheat-starch-based clamshell, will make eating those foods even more enjoyable.—By Marcia Wood, Agricultural Research Service Information Staff.

    This research is part of Quality and Utilization of Agricultural Products, an ARS National Program (#306) described on the World Wide Web at www.nps.ars.usda.gov.

    Wheat—A New Option for Carry-Out Containers was published in the September 2004 issue of Agricultural Research magazine.

    Additional comments by USDA Plant Physiologist Gregory Glenn on 9/20/2004:
    Due to a current market shortage of wheat starch, the containers will be made of corn starch. However, you bring up a very valid concern and at some point the containers may be made of wheat starch. We are very sensitive to the concerns that Celiac sufferers have regarding wheat-based products. I spoke with Dr. Bassi of MGP Ingredients. MGP is a major supplier of wheat starch. Dr. Bassi is very aware of the concerns about Celiac disease and serves on an international committee that addresses this concern. Dr. Bassi can be reached at MGP Ingredients at 800-255-0302. Let me summarize our conversation. Wheat allergens are comprised of protein or wheat gluten. The starch component itself is safe and would only be a risk if contaminated by gluten. Dr. Bassi explained that current food regulations specify that gluten levels below 200 ppm can be labeled gluten free and are deemed safe for consumption by the general public. Wheat starch produced by MGP has a protein level of 5 to 30 ppm which is well below the required 200 ppm level. Our wheat starch containers are only about 50% wheat starch and they have a film or coating on the container that provides moisture resistance.

    It would also act as a barrier between the food product and the wheat starch. Thus, a food product would not come into direct contact with the wheat starch. As I mentioned earlier, the containers are currently being made of corn starch. However, the containers would be safe, even for those with wheat allergens, if the containers were made of wheat starch.

    Thank you. This is really interesting. Who would have imagined that containers could be a possible issue?

    Thank you.

    To be labeled gluten free, it must be 20 ppm not 200 ppm and some of us cannot even tolerate that.

    Celiac.com 01/03/2009 - Recently on a gluten-free forum, I found a post asking for advice on what to do after a woman had accidentally consumed a large amount of gluten.  After unknowingly eating from her daughter’s takeout box, the woman had realized her mistake and was simply devastated to have broken her diet and subjected herself to the old, too-familiar symptoms that were on their way.
    It was interesting reading the various responses, which resulted in a debate over whether or not to induce vomiting, drink pineapple juice, take enzymes or engage in a certain illegal activity.  In all the debate, the woman eventually disappeared off the forum, which probably meant that she took some action or another, though I never heard the final result.
    This whole subject inspired some research on my part.  I first consulted my extensive gluten-free library, which led me to one solitary, repetitive answer: do not eat gluten.  In a world where doctors and authors alike are so concerned that their advice on the subject will lead people with gluten sensitivities to forgo a gluten-free diet in favor of a “band aid” of sorts, that finding a documented recommendation is near impossible.
    These experts are right to reinforce the importance of maintaining a gluten free lifestyle, and the fact that there is no “cure” for gluten intolerance and celiac disease (other than complete avoidance of gluten from wheat, barley and rye).  But mistakes do happen, and from time to time people do get "glutened,” and when they do, which action is best?
    No matter what the size is of the offending dose of gluten, all experts agree, inducing vomiting is too dangerous and disruptive to the body to be considered.  But there is one option that at least two noted experts in field of celiac research agree upon: enzymes.
    When I contacted the renowned Dr. Kenneth Fine of EnteroLab, and asked him if perhaps a dose of enzymes that are designed to break down gluten might help, he had this to say: “The good news is that everyone will survive and recover from the gluten exposure.  The enzymes you mention might help, but not completely, unless they consumed at the same time (as the gluten) for best results.”  And like all good doctors, he did go on to warn, “Avoidance is still the best policy.”
    Shari Lieberman, PhD, CNS, FACN and author of The Gluten Connection very humbly admits that “gluten slips happen.”  She also devotes a couple of pages in her book to research conducted using digestive enzymes to help manage those occasions when gluten does make its way into your diet, citing a research example in which “The study demonstrates that enzyme therapy can substantially minimize symptoms in people with celiac disease who are exposed to gluten.” 
    The enzyme used in this study does not seem to be currently available, but other gluten enzymes are at your local health food store.  I contacted one company in regard to their product, which according to them helps to reduce inflammation caused by the introduction of gluten in an individual with celiac disease or gluten intolerance.  According to them their enzymes will not prevent all damage, but may reduce some inflammation and help the body to better digest the protein.
    Ultimately, gluten sensitive individuals should recover from one accidental “gluten slip” here and there, and keeping some digestive enzymes handy to help cope with such an accident is not a bad idea.  But do keep in mind that repeated offenses, even the most minute, will damage your body and prevent it from healing.  Enzymes help treat the symptoms, but only complete avoidance of gluten can treat the disease.

    Celiac.com 05/10/2010 - Celiac is a genetic autoimmune disease which affects 1 in 100 people worldwide, making it one of the most common food intolerance's in the world. Celiac disease is triggered by the ingestion of gluten proteins, and for those sensitive to gluten, digestion of gluten grains results in an immunological response in the small intestine, destroying mature absorptive epithelial cells on the surface of the small intestine, and creating side effects ranging from severe illnesses, to no obvious symptoms what-so-ever. Regardless of your symptoms, if left untreated, celiac disease can be life-threatening.
    There is no medication to cure or alleviate celiac disease, and the only cure is complete gluten abstinence for life. Avoiding gluten, means avoiding wheat, rye and barley; which when entirely avoided can lead to recovery from celiac disease symptoms, and result in significant improvement of the intestinal mucosa and its absorptive functions.
    There is great controversy among most people who are gluten sensitive over the current market  for gluten-free products, especially breads and cereals. Most people who avoid gluten agree that gluten-free bread leaves much to be desired. Most gluten-free breads are dry, bland, and can only be tolerated when toasted and covered with lots of jam. However, Healthgrain, a European Union project  is working hard to strengthen the scientific formulas for a new generation of cereals and breads for those looking for healthy, tasty gluten-free options.
    New methods are being created  by Healthgrain, and conducted by the research team of Professor Elke Arendt, University College Cork, Ireland and the team of Professor Jan Delcour, KU Leuven, Belgium, to improve the overall quality of gluten-free products. One new method Healthgrain is exploring is the use of special Lactic acid bacteria. Lactic acid bacteria has innate properties such as anti fungal activity, which  has been shown to improve the quality and shelf-life of gluten-free breads.
    Texture is another big complaint most gluten-free people have when it comes to gluten-free products. Healthgrain has been experimenting with the effect different enzymes such as transglutaminase, glucose oxidase and protease play on the texture of gluten-free cereals. The enzymes showed that they in fact have an essential role in improving the construction of gluten-free bread, although the enzymes also showed varying reactions to the array of different gluten-free breads.
    Another technique introduced to improve  gluten-free products is something called, 'high pressure processing' (HP).  The impact of HP on the major polymers found in gluten-free flours, were also investigated by Healthgrain. The results of the impact of HP on gluten-free grains reveled that starch gelatinisation and protein network formation occurred at pressures greater than 350 MPa. However a weakening of protein structures  was discovered at lower pressures. Adding HP treated gluten-free batters to bread showed an improvement in volume and decreased staling with pressure less than 200 MPa.
    We live in a great time to be gluten-free and the scientific studies of the Healthgrain project offers more hope to gluten-free folks looking for more gluten-free products that don't taste gluten-free.

    New Improved Gluten-Free Foods Developed for Patients with Celiac Disease  


    Jefferson Adams
    Celiac.com 06/12/2014 - Here are five things people with celiac disease need regular folks to know about celiac disease:
    We are NOT on a Fad Diet—Celiac disease is not some vague, make-believe condition. Celiac disease is a potentially serious immune disorder that, if left untreated, can lead to a very deadly types of stomach, intestinal, and other cancers. Just because a bunch of people seem to think that gluten is the new high fructose corn syrup, doesn’t mean that I’m one of them. Remember, for people with celiac disease, gluten is no joke, and avoiding gluten is the only way to stay healthy. We Won’t Be Getting Over It—Currently, there is no cure for celiac disease, and the only treatment is a gluten-free diet. That’s the only way to avoid the gut damage, lower risks for other types of auto-immune conditions, and minimize the risk of various types of cancer associated with celiac disease. Celiac Disease is a Serious Condition—Since the effects of untreated celiac disease unfold slowly over time, it’s tempting for some people to look at celiac disease as a minor inconvenience. However, it’s important to understand that celiac disease is a potentially serious autoimmune disorder that, if left untreated, can leave people susceptible to other autoimmune conditions, and to deadly types of stomach, intestinal, and other cancers.  A ‘Little Gluten’ Might Hurt Me—There’s no such thing as ‘a little gluten’ to people with celiac disease. Gut damage happens with as little as 20 parts of gluten per million. That is a microscopic amount. A 'gluten-free' diet means no gluten. Period. When in Doubt, Ask—If you’re not sure if I can safely eat a certain ingredient, or a certain food, just ask. Figuring out what is or is not gluten-free can be tricky, even for me. So, it's best to ask if you're not positive. Can you think of others?

    Celiac.com 04/24/2018 - Did you know in 2017 alone, the United States had OVER TENS OF THOUSANDS of people evacuate their homes due to natural disasters such as fires, floods, hurricanes, tornadoes and tsunamis? Most evacuation sites are not equipped to feed your family the safe gluten free foods that are required to stay healthy.  Are you prepared in case of an emergency? Do you have your Gluten Free Emergency Food Bag ready to grab and go?  
    I have already lived through two natural disasters. Neither of which I ever want to experience again, but they taught me a very valuable lesson, which is why I created a Gluten Free Emergency Food Bag (see link below). Here’s my story. If you’ve ever lived in or visited the Los Angeles area, you’re probably familiar with the Santa Ana winds and how bitter sweet they are. Sweet for cleaning the air and leaving the skies a brilliant crystal blue, and bitter for the power outages and potential brush fires that might ensue.  It was one of those bitter nights where the Santa Ana winds were howling, and we had subsequently lost our power. We had to drive over an hour just to find a restaurant so we could eat dinner. I remember vividly seeing the glow of a brush fire on the upper hillside of the San Gabriel Mountains, a good distance from our neighborhood. I really didn’t think much of it, given that it seemed so far from where we lived, and I was hungry! After we ate, we headed back home to a very dark house and called it a night. 
    That’s where the story takes a dangerous turn….about 3:15am. I awoke to the TV blaring loudly, along with the lights shining brightly. Our power was back on! I proceeded to walk throughout the house turning everything off at exactly the same time our neighbor, who was told to evacuate our street, saw me through our window, assuming I knew that our hillside was ablaze with flames. Flames that were shooting 50 feet into the air. I went back to bed and fell fast asleep. The fire department was assured we had left because our house was dark and quiet again. Two hours had passed.  I suddenly awoke to screams coming from a family member yelling, “fire, fire, fire”! Flames were shooting straight up into the sky, just blocks from our house. We lived on a private drive with only one way in and one way out.  The entrance to our street was full of smoke and the fire fighters were doing their best to save our neighbors homes. We literally had enough time to grab our dogs, pile into the car, and speed to safety. As we were coming down our street, fire trucks passed us with sirens blaring, and I wondered if I would ever see my house and our possessions ever again. Where do we go? Who do we turn to? Are shelters a safe option? 
    When our daughter was almost three years old, we left the West Coast and relocated to Northern Illinois. A place where severe weather is a common occurrence. Since the age of two, I noticed that my daughter appeared gaunt, had an incredibly distended belly, along with gas, stomach pain, low weight, slow growth, unusual looking stool, and a dislike for pizza, hotdog buns, crackers, Toast, etc. The phone call from our doctor overwhelmed me.  She was diagnosed with Celiac Disease. I broke down into tears sobbing. What am I going to feed my child? Gluten is everywhere.
    After being scoped at Children's Hospital of Chicago, and my daughters Celiac Disease officially confirmed, I worried about her getting all the nutrients her under nourished body so desperately needed. I already knew she had a peanut allergy from blood tests, but just assumed she would be safe with other nuts. I was so horribly wrong. After feeding her a small bite of a pistachio, which she immediately spit out, nuts would become her enemy. Her anaphylactic reaction came within minutes of taking a bite of that pistachio. She was complaining of horrible stomach cramps when the vomiting set in. She then went limp and starting welting. We called 911.
    Now we never leave home without our Epipens and our gluten free food supplies. We analyze every food label. We are hyper vigilant about cross contamination. We are constantly looking for welts and praying for no stomach pain. We are always prepared and on guard. It's just what we do now. Anything to protect our child, our love...like so many other parents out there have to do every moment of ever day!  
    Then, my second brush with a natural disaster happened, without any notice, leaving us once again scrambling to find a safe place to shelter. It was a warm and muggy summer morning, and my husband was away on a business trip leaving my young daughter and me to enjoy our summer day. Our Severe Weather Alert Radio was going off, again, as I continued getting our daughter ready for gymnastics.  Having gotten used to the (what seemed to be daily) “Severe Thunderstorm warning,” I didn’t pay much attention to it. I continued downstairs with my daughter and our dog, when I caught a glimpse out the window of an incredibly black looking cloud. By the time I got downstairs, I saw the cover to our grill literally shoot straight up into the air. Because we didn’t have a fenced in yard, I quickly ran outside and chased the cover, when subsequently, I saw my neighbor’s lawn furniture blow pass me. I quickly realized I made a big mistake going outside. As I ran back inside, I heard debris hitting the front of our home.  Our dog was the first one to the basement door! As we sat huddled in the dark corner of our basement, I was once again thinking where are we going to go if our house is destroyed. I was not prepared, and I should have been. I should have learned my lesson the first time. Once the storm passed, we quickly realized we were without power and most of our trees were destroyed. We were lucky that our house had minimal damage, but that wasn’t true for most of the area surrounding us.  We were without power for five days. We lost most of our food - our gluten free food.
    That is when I knew we had to be prepared. No more winging it. We couldn’t take a chance like that ever again. We were “lucky” one too many times. We were very fortunate that we did not lose our home to the Los Angeles wildfire, and only had minimal damage from the severe storm which hit our home in Illinois.
      
    In 2017 alone, FEMA (Federal Emergency Management Agency) had 137 natural disasters declared within the United States. According to FEMA, around 50% of the United States population isn’t prepared for a natural disaster. These disasters can happen anywhere, anytime and some without notice. It’s hard enough being a parent, let alone being a parent of a gluten free family member. Now, add a natural disaster on top of that. Are you prepared?

    Celiac.com 04/23/2018 - A team of researchers recently set out to learn whether celiac disease patients commonly suffer cognitive impairment at the time they are diagnosed, and to compare their cognitive performance with non-celiac subjects with similar chronic symptoms and to a group of healthy control subjects.
    The research team included G Longarini, P Richly, MP Temprano, AF Costa, H Vázquez, ML Moreno, S Niveloni, P López, E Smecuol, R Mazure, A González, E Mauriño, and JC Bai. They are variously associated with the Small Bowel Section, Department of Medicine, Dr. C. Bonorino Udaondo Gastroenterology Hospital; Neurocience Cognitive and Traslational Institute (INECO), Favaloro Fundation, CONICET, Buenos Aires; the Brain Health Center (CESAL), Quilmes, Argentina; the Research Council, MSAL, CABA; and with the Research Institute, School of Medicine, Universidad del Salvador.
    The team enrolled fifty adults with symptoms and indications of celiac disease in a prospective cohort without regard to the final diagnosis.  At baseline, all individuals underwent cognitive functional and psychological evaluation. The team then compared celiac disease patients with subjects without celiac disease, and with healthy controls matched by sex, age, and education.
    Celiac disease patients had similar cognitive performance and anxiety, but no significant differences in depression scores compared with disease controls.
    A total of thirty-three subjects were diagnosed with celiac disease. Compared with the 26 healthy control subjects, the 17 celiac disease subjects, and the 17 disease control subjects, who mostly had irritable bowel syndrome, showed impaired cognitive performance (P=0.02 and P=0.04, respectively), functional impairment (P<0.01), and higher depression (P<0.01). 
    From their data, the team noted that any abnormal cognitive functions they saw in adults with newly diagnosed celiac disease did not seem not to be a result of the disease itself. 
    Their results indicate that cognitive dysfunction in celiac patients could be related to long-term symptoms from chronic disease, in general.

    Celiac.com 04/21/2018 - Dear Friends and Readers,
    I have been writing articles for Scott Adams since the 2002 Summer Issue of the Scott-Free Press. The Scott-Free Press evolved into the Journal of Gluten Sensitivity. I felt honored when Scott asked me ten years ago to contribute to his quarterly journal and it's been a privilege to write articles for his publication ever since.
    Due to personal health reasons and restrictions, I find that I need to retire. My husband and I can no longer travel the country speaking at conferences and to support groups (which we dearly loved to do) nor can I commit to writing more books, articles, or menus. Consequently, I will no longer be contributing articles to the Journal of Gluten Sensitivity. 
    My following books will still be available at Amazon.com:
    Gluten-free Cooking for Dummies Student's Vegetarian Cookbook for Dummies Wheat-free Gluten-free Dessert Cookbook Wheat-free Gluten-free Reduced Calorie Cookbook Wheat-free Gluten-free Cookbook for Kids and Busy Adults (revised version) My first book was published in 1996. My journey since then has been incredible. I have met so many in the celiac community and I feel blessed to be able to call you friends. Many of you have told me that I helped to change your life – let me assure you that your kind words, your phone calls, your thoughtful notes, and your feedback throughout the years have had a vital impact on my life, too. Thank you for all of your support through these years.

    Celiac.com 04/20/2018 - A digital media company and a label data company are teaming up to help major manufacturers target, reach and convert their desired shoppers based on dietary needs, such as gluten-free diet. The deal could bring synergy in emerging markets such as the gluten-free and allergen-free markets, which represent major growth sectors in the global food industry. 
    Under the deal, personalized digital media company Catalina will be joining forces with Label Insight. Catalina uses consumer purchases data to target shoppers on a personal base, while Label Insight works with major companies like Kellogg, Betty Crocker, and Pepsi to provide insight on food label data to government, retailers, manufacturers and app developers.
    "Brands with very specific product benefits, gluten-free for example, require precise targeting to efficiently reach and convert their desired shoppers,” says Todd Morris, President of Catalina's Go-to-Market organization, adding that “Catalina offers the only purchase-based targeting solution with this capability.” 
    Label Insight’s clients include food and beverage giants such as Unilever, Ben & Jerry's, Lipton and Hellman’s. Label Insight technology has helped the Food and Drug Administration (FDA) build the sector’s very first scientifically accurate database of food ingredients, health attributes and claims.
    Morris says the joint partnership will allow Catalina to “enhance our dataset and further increase our ability to target shoppers who are currently buying - or have shown intent to buy - in these emerging categories,” including gluten-free, allergen-free, and other free-from foods.
    The deal will likely make for easier, more precise targeting of goods to consumers, and thus provide benefits for manufacturers and retailers looking to better serve their retail food customers, especially in specialty areas like gluten-free and allergen-free foods.

    Celiac.com 04/19/2018 - Previous genome and linkage studies indicate the existence of a new disease triggering mechanism that involves amino acid metabolism and nutrient sensing signaling pathways. In an effort to determine if amino acids might play a role in the development of celiac disease, a team of researchers recently set out to investigate if plasma amino acid levels differed among children with celiac disease compared with a control group.
     
    The research team included Åsa Torinsson Naluai, Ladan Saadat Vafa, Audur H. Gudjonsdottir, Henrik Arnell, Lars Browaldh, and Daniel Agardh. They are variously affiliated with the Institute of Biomedicine, Department of Microbiology & Immunology, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; the Institute of Clinical Sciences, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden; the Department of Pediatric Gastroenterology, Hepatology and Nutrition, Karolinska University Hospital and Division of Pediatrics, CLINTEC, Karolinska Institute, Stockholm, Sweden; the Department of Clinical Science and Education, Karolinska Institute, Sodersjukhuset, Stockholm, Sweden; the Department of Mathematical Sciences, Chalmers University of Technology, Gothenburg, Sweden; the Diabetes & Celiac Disease Unit, Department of Clinical Sciences, Lund University, Malmö, Sweden; and with the Nathan S Kline Institute in the U.S.A.
    First, the team used liquid chromatography-tandem mass spectrometry (LC/MS) to analyze amino acid levels in fasting plasma samples from 141 children with celiac disease and 129 non-celiac disease controls. They then crafted a general linear model using age and experimental effects as covariates to compare amino acid levels between children with celiac disease and non-celiac control subjects.
    Compared with the control group, seven out of twenty-three children with celiac disease showed elevated levels of the the following amino acids: tryptophan; taurine; glutamic acid; proline; ornithine; alanine; and methionine.
    The significance of the individual amino acids do not survive multiple correction, however, multivariate analyses of the amino acid profile showed significantly altered amino acid levels in children with celiac disease overall and after correction for age, sex and experimental effects.
    This study shows that amino acids can influence inflammation and may play a role in the development of celiac disease.
