Gluten intolerance

Gluten-related disorders, including celiac disease, wheat allergy, and non-celiac gluten sensitivity, have emerged as a significant phenomenon affecting people worldwide, with an estimated prevalence of nearly 5% globally. The only currently available treatment for this disease involves the exclusion of gluten from the diet, which is particularly challenging in the case of bakery products. Gluten-free bread (GFB) presents certain disadvantages when compared to traditional wheat bread, including inferior sensory attributes, technological characteristics, and lower protein and fiber content...

Most adverse reactions to food are patient self-reported and not based on validated tests but nevertheless lead to dietary restrictions, with patients believing that these restrictions will improve their symptoms and quality of life. We aimed to clarify the myths and reality of common food intolerances, giving clinicians a guide on diagnosing and treating these cases. We performed a narrative review of the latest evidence on the widespread food intolerances reported by our patients, giving indications on the clinical presentations, possible tests, and dietary suggestions, and underlining the myths and reality...

The consumption of out-of-home meals is increasing. This study is aimed at assessing the effect of an intervention on healthy offerings and the management of food allergies and intolerances. Ten (control group) and eight restaurants (intervention group) were randomized in a 12-month parallel controlled trial. The outcomes were changes regarding adherence to the Mediterranean diet (AMed) and gluten management (SMAP) criteria, the traffic light rating category, nutrients, and gluten- and allergen-free content of dishes...

BACKGROUND AND AIM: Low-fermentable oligo-, di-, and monosaccharides and polyol (FODMAP) diets have been recommended for individuals with food intolerance and irritable bowel syndrome (IBS). Individual food intolerances may, however, not correspond to the FODMAP content alone. METHODS: We conducted a survey on self-reported intolerance to articles of food commonly identified as high FODMAP in 400 healthy Indian subjects (median age 40 years; 69% men) and 204 consecutive consenting patients with IBS (median age 36 years; 58% men)...

Quinoa ( Chenopodium quinoa Willd.) is a pseudocereal with rich nutritional composition, gluten free, and organoleptic. The primary aim of this study was to elucidate the possible protective roles of quinoa in glucose homeostasis in a model of cafeteria diet-induced obesity. Male Wistar rats (3 weeks of age) were randomly allocated to be fed by; control chow (CON; n  = 6), quinoa (QUI; n  = 6), cafeteria (CAF; n  = 6), or quinoa and cafeteria (CAFQ; n  = 6) for 15 weeks...

The popularity of "free-from" food products (FFFPs), which exclude several ingredients such as lactose, gluten, or sugar, is increasing globally. However, experts agree that avoiding these ingredients without medical reasons can lead to nutritional deficiencies. A representative consumer survey was conducted in Hungary ( n = 1002); it focused on behaviors related to FFFPs, particularly lactose- and gluten-free products. This study revealed that consumers often consider "free-from" claims during shopping. Lactose- and gluten-free foods were popular, even among those without specific dietary needs...

Celiac disease (CD) is a chronic inflammation of the small intestine triggered by gluten ingestion in genetically predisposed people. Recent literature studies highlight the possible role of the gut microbiota in the pathogenesis of this disease. The gut microbiota is a complex community of microorganisms that can interact with the innate and adaptative immune systems. A condition of dysbiosis, which refers to an alteration in the composition and function of the human gut microbiota, can lead to a dysregulated immune response...

BACKGROUND: Wheat sensitivity is a collective term for several, especially gastrointestinal, diseases that occur as part of a hypersensitivity reaction after wheat consumption. The symptoms, which are mostly similar to those of irritable bowel syndrome, are often accompanied by skin lesions. In addition to celiac disease and dermatitis herpetiformis, the cutaneous manifestation of celiac disease, wheat sensitivity also includes nonceliac gluten sensitivity (NCGS), allergic nickel contact mucositis, wheat allergy, amylase-trypsin inhibitor intolerance, and fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) intolerance...

Celiac disease, non-celiac gluten sensitivity, and wheat allergy comprise 3 of the main conditions with wheat- and gluten-containing foods as the symptom trigger. Distinguishing between these entities can be daunting. In this review, we compare and contrast celiac disease, non-celiac gluten sensitivity, and wheat allergy to allow clinicians to determine which diagnosis fits their patient to facilitate high-quality management and longitudinal care.

Celiac disease or gluten-sensitive enteropathy is a relevant health concern in today's world. Three prerequisites need to be met to trigger the disease, namely a genetic predisposition, gluten consumption, and environmental factors. Retrospective studies conducted across all age groups have ruled out the possibility that improved diagnostic methods were behind the increased prevalence. Since the genetic predisposition is more or less constant in the population, it is assumed that external factors may play a major role in this increase...

Gluten sensitivity is defined as a chronic intolerance to gluten ingestion in genetically predisposed individuals. The etiology is thought to be immune-mediated and has a variable dermatologic presentation. Celiac disease (CD) is one of the most common forms of gluten intolerance and encompasses a wide range of extra-intestinal pathology, including cutaneous, endocrine, nervous, and hematologic systems. Psoriasis, another long-term inflammatory skin condition, has been linked to significant symptomatic improvement with a gluten-free diet (GFD)...

Clinicians are faced with evaluating real and alleged reactions to foods that may be allergic or nonallergic. Pathogenesis, diagnosis, and treatment of various non-IgE-mediated diseases are discussed in this review. These food-related conditions range from mild to severe. Referral for an allergy workup may be pursued despite the lack of IgE-mediated symptoms. Diagnostic testing is available for defined non-IgE-mediated food diseases that are either immunologic or nonimmunologic. These include celiac disease and related disorders, carbohydrate maldigestion, pancreatic insufficiency, and histamine intolerance...

Symptoms of the disorders across the irritable bowel syndrome (IBS) spectrum include several different, usually postprandial, abdominal complaints. Up to date, dietary treatments of the IBS have neither been personalized nor diagnosed with sufficient scientific evidence. They have mostly been treated using 'one-size-fits-all' approaches. Such include exclusion diets, a low fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet, and gluten-free diets, lactose-free diets, a diet recommended by the UK National Institute for Health and Care Excellence, and a wheat-free diet...

PURPOSE: Gluten-free diets have gained popularity worldwide. However, little information is available regarding the knowledge of, and behaviors toward, this diet among adults in KSA. This study was aimed at addressing this knowledge gap. METHODS: A cross-sectional survey was conducted in 352 women at a health sciences university in KSA. RESULTS: Eleven percent of participants had followed a gluten-free diet at least once, 70% of whom had voluntarily tried this diet without a confirmed medical diagnosis...

One of the challenges of the food industry is detecting the potential of novel non-dairy food matrices to deliver probiotic bacteria to humans as cholesterol-free products, suitable for people with lactose intolerance and sensitivity to dairy proteins. In this study, the possibility of adding sprouted quinoa milk (SQM) at 0%, 50%, and 100% levels in probiotic non-dairy dessert containing native Lactobacillus plantarum isolated from camel milk was investigated. Physicochemical, functional, microbiological, color, texture, and organoleptic characteristics of probiotic dessert samples were evaluated during 1, 7, and 14 days of storage at 4°C...

Gluten is the main fraction of wheat proteins. It is widely used in the food industry because of the properties that are generated in the dough, but it is also able to trigger diseases like allergies, autoimmunity processes (such as celiac disease), and intolerances in sensitized persons. The most effective therapy for these diseases is the total avoidance of gluten in the diet because it not only prevents damage but also enhances tissue healing. To ensure the absence of gluten in food products labeled as gluten-free, accurate detection systems, like immunoassays, are required...

UNLABELLED: Cardiac conduction disorder may have a wide range of aetiology and can manifest with symptomatic bradycardia and syncope. Celiac disease is a malabsorptive long-term autoimmune disorder where the small intestine is the primarily affected organ due to gluten intolerance in genetically predisposed individuals. The associations between celiac disease and cardiac pathology are uncommon. We report a case of a 50-year-old woman with a known case of celiac disease who presented with a symptomatic cardiac conduction abnormality that improved with a gluten-free diet...

Gluten, a group of ethanol-soluble proteins present in the endosperm of cereals, is extensively used in the food industry due to its ability to improve dough properties. However, gluten is also associated with a range of gluten-related diseases (GRDs), such as wheat allergies, celiac disease, and gluten intolerance. The recommended treatment for GRDs patients is a gluten-free diet. To monitor adherence to this diet, it is necessary to develop gluten-detection systems in food products. Among the available methods, immunodetection systems are the most popular due to their simplicity, reproducibility, and accuracy...

INTRODUCTION: Laryngopharyngeal reflux (LPR) is one of the most common conditions encountered in otolaryngology. Gluten sensitivity may mimic the signs and symptoms of LPR or act as an aggravating cofactor with LPR. Gluten sensitivity and food intolerance also have been implicated as conditions that may be associated specifically with LPR symptoms and signs resistant to traditional medical treatment. Medical management of LPR may be insufficient to control symptoms and laryngeal signs of reflux, constituting resistant LPR...

Celiac disease (CD) is a complex immune disorder of the intestine that developes in genetically susceptible individuals. CD develops as an intolerance to ingested gluten proteins (gliadins, secalins, hordeins and avenins), being gliadin one of the most immunogenic. Here we present a protocol for the preparation of digested gliadin for laboratory use, a fundamental axis for in vitro and in vivo stimulation studies related to celiac disease research. The importance of a scrupulous handling of materials, products and laboratory instruments to achieve a lipopolysaccharide free gliadin is explained and emphasized...
