Azido linoleiko konjokatua: obesitatearen aurkako irtenbidea ala mehatxua?

Obesitatea etengabe nagusitzen doa, bereziki mendebaldeko gizarteetan, eta oraindik ez da aurkitu gaixotasun horren aurkako tratamendu arrakastatsurik. Aukera posibleen artean, azpimagarria da elikagai funtzionalek azken urteotan hartu duten indarra. Elikagai horien osagaietako bat Azido Linoleiko Konjokatua (CLA) da, animalia hausnarkarien haragian eta esne eta esnekietan naturalki dagoen gantz azidoa. 80. hamarkadatik gaur arte ugari izan dira lipido horren inguruan egindako ikerketak eta berari esleitutako efektu onuragarriak. Horrela, frogatu da gantz horrek gorputz-pisua eta gantz-masa erregula ditzakeela, minbizi-sormena ekidin dezakeela eta gaixotasun kardiobaskularren arriskua ere jaitsi dezakeela. In vitro zein esperimentazio-animalietan in vivo eginiko hainbat ikerketak agerian utzi dute CLAk gantz-ehunaren pisua murriz dezakeela gantz-pilaketa inhibituz eta gantzaren oxidazioa suspertuz. Gizakietan lorturiko datuak, ordea, askoz urriagoak dira, ez dira horren erabakiorrak eta emaitz gehiagoren beharra dago. Molekula horren segurtasunaren ildoan ere, emaitza kontrajarriak plazaratu dira eta beraz, ez da oraindik efektu desiragaitz zehatzik azpimarratzen. Dena den, merkaturatu den molekula funtzional baten aurrean egoteak zuhurtasuna eskatzen du, are gehiago oraindik gizakietan aski frogatu diren zenbait efektu egotzi zaizkiolarik eta bere albo ondorioei buruzko datu nahikorik ere ez dagoelarik

Celiac Male’s Gluten-Free Diet Profile: Comparison to that of the Control Population and Celiac Women

The aim of the present work was to analyze the body composition and dietary profile of Spanish celiac men and to compare them to control men and celiac women from our previous studies. Forty-two celiac men (31.5 +/- 11.9 years) were recruited and anthropometric measurements were taken. Analysis of energy consumption, macro-and micronutrient intake and food frequency consumption was carried out. Celiac men were more overweight and obese than celiac women, but less than the control population, reporting the same energy intake and macronutrient distribution. Most micronutrient deficiencies in celiac men were not directly related to a gluten free diet; these were also observed for the entire population. The least adherence to Dietary Reference Intakes in women was reported for iron, iodine, potassium and selenium, whereas magnesium intake was higher than in men. Among celiac participants (both genders), cereal, vegetable and legume consumption was poor and meat intake was contrastingly excessive. In conclusion, the dietary profile of celiac men is as unbalanced as that of control men but slightly more than that of celiac women. General nutritional education should be given to both general and celiac populations, and specific advices to celiac men, in order to decrease the risk of celiac disease-related pathologies.Idoia Larretxi is a fellowship of the University of the Basque Country, UPV/EHU (Euskararen eta Etengabeko Prestakuntzaren arloko Errektoreordetza).

Uncovering the Concerns and Needs of Individuals with Celiac Disease: A Cross-Sectional Study

The treatment for celiac disease (CD) involves a strict gluten-free diet, which can be challenging and lead to questions for patients. Pinpointing these uncertainties can enable the creation of efficient educational resources. In this study, a questionnaire was specifically designed to gain insights into the knowledge, concerns, and needs of individuals with CD and their supporters. The questionnaire was distributed through the Instagram social network and received adequate responses from 300 participants, 258 (86%) being female and 152 (50.7%) falling in the age range of 25–44 years. The concerns of individuals with celiac disease and celiac supporters were rated on a 1–4 scale, with a mean score of 3.5 indicating significant concern. A total of 255 (85%) of all participants expressed that their principal concern was the social limitations they faced, such as difficulties in eating out and sharing food with others. Every participant evaluated their overall disease knowledge, averaging at 2.92 out of 4, indicating a reasonable level of awareness. When asked if they believed that improving general knowledge about CD in the general population would enhance their quality of life, the vast majority responded affirmatively. This finding underscores the importance of not only educating individuals with CD but also reaching out to the wider population, especially those who have a direct impact on the daily lives of individuals with CD, such as family members, friends, and food service providers.Maialen Vázquez-Polo and Gesala Perez-Junkera are fellowships of the University of the Basque Country, UPV/EHU, and the Basque Government, respectively.

Gluten and FODMAPs Relationship with Mental Disorders: Systematic Review

Nowadays, gluten and FODMAP food components (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) are increasingly studied due to their possible relation with extraintestinal-associated conditions. In recent years, gluten-free diets (GFD) and low-FODMAP diets (LFD) are becoming more popular not only in order to avoid the food components that cause intolerances or allergies in some people, but also due to the direct influence of marketing movements or diet trends on feeding habits. Likewise, neurological and psychiatric diseases are currently of increasing importance in developed countries. For this reason, a bibliographic systematic review has been carried out to analyse whether there is a pathophysiological relationship between the dietary intake of gluten or FODMAPs with mental disorders. This review collects 13 clinical and randomized controlled trials, based on the PRISMA statement, which have been published in the last ten years. Based on these results, limiting or ruling out gluten or FODMAPs in the diet might be beneficial for symptoms such as depression, anxiety (7 out of 7 articles found any positive effect), or cognition deficiency (improvements in several cognition test measurements in one trial), and to a lesser extent for schizophrenia and the autism spectrum. Nevertheless, further studies are needed to obtain completely reliable conclusions.Silvia Matias is IKASIKER fellowships of the Education Department of the Basque Government.

New Software for Gluten-Free Diet Evaluation and Nutritional Education

Following a gluten-free diet (GFD) is the only treatment for celiac disease. This diet must ensure the absence of gluten but also needs to be nutritionally balanced. Dietitians working in this field cannot properly evaluate energy and nutrient intake of celiac people because dietary programs available on the market do not contain the nutritional composition of gluten-free products (GFP). Here we present a new GFD evaluation software that contains more than 700 gluten-free rendered foodstuffs and their macronutrient composition. Apart from diet evaluation and design, the software represents a tool for nutritional education as well, since it shows diet appropriacy and indicates how to promote balanced self-care. Moreover, anthropometric and biochemical data or symptoms presence and diet adherence can be recorded and evaluated. This open free software, can be downloaded in its app format for mobiles and tablets. Software evaluation indicated its correct functionality and the importance of assessing a GFD with GFP instead of with their gluten-containing analogues. Thus, this software represents an essential e-Health tool, not only for proper GFD evaluation, but also for improving life quality of celiac and gluten sensitive people.This research was supported by two grants from the University of the Basque Country, Vitoria-Gasteiz, Spain (UPV/EHU) (University-Society US15/06 and US18/15)

Gluten Assessment in Beers: Comparison by Different Commercial ELISA Kits and Evaluation of NIR Analysis as a Complementary Technique

Traditionally, beers are made with gluten-containing cereals. It is crucial to have rapid analytical methodologies that allow gluten content control of the beers for celiac consumers. We assess the content of gluten in 65 conventional and 41 gluten-free labeled beers commercialized in Europe and compare the results in a subgroup of 71 beers with three ELISA kits. This research allows gathering information on the potential complementary utility of NIR analysis applied to gluten analysis of gluten-free beers in terms of time saving. Results obtained with the ELISA technique identified competitive R5 to be the most sensitive in detecting the prolamins, by eliciting a higher number of beers containing gluten above 20 mg/kg. The gluten content in conventional beers tested increased with the presence of wheat as raw material and with the use of ale-type yeasts. By using competitive R5, 3 out of the 41 gluten-free labeled beers appeared to contain gluten above 20 mg/kg, and conversely, 15 out of 65 of the conventional beers showed a gluten content below this threshold. According to our approaches, NIR did not achieve a suitable correlation with ELISA results, neither for gluten quantification nor for discrimination, and therefore, it cannot be proposed as a complementary technique.This research was funded by the Associació SMAP—Celíacs Catalunya.

Micronutrient Analysis of Gluten-Free Products: Their Low Content Is Not Involved in Gluten-Free Diet Imbalance in a Cohort of Celiac Children and Adolescent

Data about the nutritional composition of gluten-free products (GFP) are still limited. Most studies are based on ingredient and nutrition information described on the food label. However, analytical determination is considered the gold standard for compositional analysis of food. Micronutrient analytical content differences were observed in a selection of GF breads, flakes and pasta, when compared with their respective gluten-containing counterparts. In general terms, lower iron, piridoxin, riboflavin, thiamin, niacin, folate, manganese and vitamin B5 can be underlined. Variations in biotin and vitamin E content differed among groups. In order to clarify the potential contribution of the GFP to the gluten-free diet's (GFD) micronutrient shortages, analytical data were used to evaluate GFD in a cohort of celiac children and adolescent. Participants did not reach recommendations for vitamin A, vitamin E, folic acid, vitamin D, biotin, iodine, and copper. It does not seem that the lower micronutrient content of the analyzed GFP groups contributed to the micronutrient deficits detected in GFD in this cohort, whose diet was not balanced. Nevertheless, GFP fortification for folate and biotin is proposed to prevent the deficiencies observed in GFD, at least in the case of pediatric celiac disease.Idoia Larretxi is a fellowship of the University of the Basque Country, UPV/EHU.

FODMAP Intake in Spanish Population: Open Approach for Risk Assessment

Fermentable oligo-, di- and monosaccharides and polyols’ (FODMAP) were related with intestinal complications. The present study aimed to determine the FODMAP consumption of Spanish children, adolescents and adults, analyzing the real FODMAP risk of foods, and to set an open methodology for the measurement of this intake in other regions as well as nutrient intake assurance. Total fructan analysis was performed analytically in eighty-seven food samples. Daily intake of FODMAPs, fiber and micronutrients was calculated by combining the food composition for selected fermentable carbohydrates with the national food consumption stratified by age in an open software. Spanish child and adolescent total FODMAP consumption was settled as 33.4 ± 92.4 and 27.3 ± 69.0 g/day, respectively. Both intakes were higher than that of the adult population (21.4 ± 56.7 g/day). The most important food sources of lactose, excess of fructose and total fructan, considering their content and dietary intake were different between age groups. The contribution of these foods to dietary calcium and fiber and the consequent risk of deficiency if they are withdrawn was highlighted. We demonstrated the relevance of stratifying the total FODMAP intake by age. An open approach for FODMAP intake quantification and nutrient control was provided.Maialen Vazquez-Polo and Gesala Perez-Junkera are IKASIKER fellowships of the Education Department of the Basque Government.
