Modulation of in vitro digestibility and physical characteristics of protein enriched gluten free breads by defining hydration

Publication date: January 2020Source: LWT, Volume 117Author(s): Marta Sahagún, Yaiza Benavent-Gil, Cristina M. Rosell, Manuel GómezAbstractThe association of diabetes on celiac disease together with the high glycemic index of gluten-free breads makes necessary the pursuit of a solution to reduce this glycemic response. Protein enrichment and changes on hydration level may be tools to get it. Thus, the aim of this study was to analyze the effect of two proteins (pea and egg white) on the digestibility and physical characteristics of gluten-free breads, with either the same hydration or specific volume. Protein enriched breads were made blending starch and proteins (70:30). Breads prepared at constant hydration presented lower specific volume and weight loss during baking, and higher hardness than control. However, when the specific volume was matched, the breads with egg white protein presented lower weight loss and higher hardness, while the ones with pea protein were the less hard. Protein enriched breads showed higher SDS and lower RDS values than control with constant hydration, but lower SDS values and glucose release with constant specific volume. Therefore, the bread volume influenced not only the physical properties but also the bread digestibility.

AbstractAimPatients with celiac disease (CeD) are prone to develop other autoimmune diseases such as autoimmune thyroid disease and type 1 diabetes. While 7.5% of first-degree relatives (FDRs) of patients with CeD develop CeD, it is not clear whether FDRs of patients with CeD are at higher risk of developing autoimmune thyroid disease.MethodsIn this prospective case-control study, we recruited 194 FDRs (males 53.1%) of 91 patients with CeD and 140 age-matched healthy controls (males 76.4%). They were screened for CeD using anti-tissue transglutaminase antibodies (anti-tTG Ab) and thyroid disease using a symptom questionnai...

Conclusion: Patients with type 1 DM should be examined for thyroid diseases, and patients with suspected thyroid disease should be evaluated with a thyroid ultrasound. Type 1 DM and PTC coexistence albeit very rare; It should be known that type 1 diabetes can be seen together with thyroid cancer. PMID: 31686641 [PubMed - as supplied by publisher]

More recently, the NF-κB signaling was also reported to be regulated by several long non-coding RNAs (lncRNAs) that constitute the major portion of the noncoding component of the human genome.

Conclusion: This study is the largest to date analyzing the potential influence of neighborhood deprivation on ADs. Our results indicate that neighborhood deprivation may affect risk of ADs, independent of individual level sociodemographic characteristics. For health care policies, both individual and neighborhood level approaches seem to be of importance.

Abstract Trials of antigen-specific tolerance have been undertaken in the clinic for over fifty years and the results of these antigen-specific clinical trials are described in this review. Antigen-specific tolerization of the immune system in protein replacement therapy for hemophilia A is an accepted treatment. Clinical trials are ongoing for autoimmune conditions such as type 1 diabetes, multiple sclerosis, neuromyelitis optica, and rheumatoid arthritis with various antigen-specific strategies. Trials for tolerization in celiac disease aim for antigen specific tolerance to gluten, an environmental trigger, whic...

Abstract Celiac disease is a complex autoimmune enteropathy of the small intestine that commonly occurs in genetically predisposed individuals due to intake of gluten and related proteins. Gluten consumption, duration of breast-feeding, various infections, especially frequent intestine infections, vaccinations and use of antibiotics can be linked to celiac disease. It is predicted that it affects 1% of the global population and its incidence rate is increasing. Celiac disease is closely related to Turner's syndrome, type I diabetes mellitus, Down's syndrome, and other autoimmune conditions and most people with the...

M. Yassine For a long time, viruses have been shown to modify the clinical picture of several autoimmune diseases, including type 1 diabetes (T1D), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjögren’s syndrome (SS), herpetic stromal keratitis (HSK), celiac disease (CD), and multiple sclerosis (MS). Best examples of viral infections that have been proposed to modulate the induction and development of autoimmune diseases are the infections with enteric viruses such as Coxsackie B virus (CVB) and rotavirus, as well as influenza A viruses (IAV), and herpesviruses. Other viruses that ...

(CNN) — Bad news for lovers of bread, pasta and baked goods: Eating lots of gluten-heavy foods from a young age could eventually lead to gluten intolerance. A study published Tuesday in the journal JAMA suggests that eating higher-than-normal levels of gluten during the first five years of life can increase a child’s likelihood of developing celiac disease, a digestive disorder that damages the small intestine. Higher gluten intake was associated with a 6.1% increased risk of celiac disease autoimmunity, an immunological response to gluten, and a 7.2% increased risk of celiac disease per each additional gram or...
