RESUMEN

INTRODUCTION: dysphagia involves a difficulty in the displacement of food or drink from the mouth to the stomach, which may consist of a delay or an impossibility of transit or an-error in the direction, with the consequent passage to the airway. Dysphagia increases the risk of malnutrition and dehydration in the patient. However, dehydration, although one of the most common complications of dysphagia and associated with significant risks, including hospitalization and mortality, has been little studied in terms of its relationship and associated risk factors. METHODS: a review of the scientific literature on the hydration of people with dysphagia and the dangers of inadequate hydration in them was carried out. RESULTS AND DISCUSSION: the dietary and nutritional approach in patients with dysphagia requires a multidisciplinary and personalized approach and is essential to improve the quality of life of patients with dysphagia. Dehydration is a frequent and serious complication in patients with dysphagia, which can lead to problems such as urinary tract infections, constipation, confusion, and worsening of chronic diseases. Therefore, it is crucial to carefully evaluate and monitor the fluid intake of these patients, and strategies to improve hydration include the use of thickened liquids, stimulating appetite, and adapting the texture and presentation of foods. Conclusión: adequate and protocolized management, from a dietary and nutritional point of view, can have a significant impact on the quality of life of patients, improving their well-being and preventing complications associated with this condition. The comprehensive approach to dysphagia, which includes adequate assessment and management of hydration, is essential to prevent serious complications.

RESUMEN

More and more functions related to vitamin D and more pathologies related to its deficiency are known. The deficiency that exists in vitamin D is known at all ages, sexes and throughout the world. But beyond the existing deficiencies in each population group, in this article we intend to analyze how the nutritional situation of this vitamin in pregnant women and during lactation can have influence on the future health of their offspring.

RESUMEN

Yogurt has been valued very positively for centuries, but the concern for food sustainability and the fact that it is a food of animal origin has raised doubts about the consumption that may be convenient. The objective of this work is to deepen the topic and establish recommendations for the population. From the nutritional point of view, yogurt is a valuable food, for its high content, quality and bioavailability of its nutrients, in a low energy content, its components together with probiotic microorganisms are provided in a matrix that helps achieve greater nutritional and health benefit. Regular consumption of yogurt has been linked to cardiovascular protection, against diabetes, excess weight, cancer, bone health. Thinking about environmental sustainability, yogurt production is not particularly dangerous, as the kg of CO2 eq (greenhouse gases) associated with their production are the lowest obtained compared to other animal foods and even lower than those associated with the production of some plant foods and the supply of nutrients per 1000 kcal, per 100 g, or per euro is one of the highest available. There is the possibility to further improve sustainability with improvements in animal feed, packaging, transport, etc. Considering this evidence, the daily consumption of yogurt / fermented milk should be included in the food guidelines, not only as one more milk option, but specifying a specific consumption such as a ration / day, this pattern can be useful from the nutritional point of view and for the improvement of public health.

RESUMEN

BACKGROUND: Childhood overweight and obesity is a global concern and has increased in Spain over the last decades. Combinations of lifestyle behaviors (i.e., diet, sleep, and sedentarism) are highly related to weight status. Therefore, this study aimed to identify lifestyle patterns among children from Madrid City, and analyze associations with the prevalence of overweight, obesity, and abdominal obesity, considering socio-economic factors. METHODS: A cross-sectional analysis was conducted on 4545 children from the ENPIMAD study with data on diet, sleep, anthropometric, and socio-economic variables. K-means cluster analysis was used to identify lifestyle clusters, and logistic regressions were used to examine the associations between socio-economic indicators and cluster membership, and between clusters and weight status. RESULTS: Findings show three lifestyle clusters (healthy, mixed, and unhealthy), with boys and older children more represented in the unhealthy cluster. Food insecurity and low socio-economic status were associated with unhealthier clusters in boys and girls. Children in unhealthier clusters were more likely to have obesity and abdominal obesity. However, these associations disappeared in girls after controlling for food insecurity. CONCLUSION: These results provide insight into the combination of behaviors and socio-economic factors associated with childhood obesity that may aid in the design of future interventions.

RESUMEN

Proteins are macronutrients with multiple health benefits, but excessive consumption can negatively affect health. This study aimed to evaluate the characteristics of a sample of high-protein processed foods (HPPFs), describe how their consumption affects dietary balance, and acquire knowledge of the consumption patterns of these products in a Spanish population. A sample of HPPFs available in supermarkets and on websites was collected. The contribution to recommended protein intakes was calculated using national and international references and considering the single consumption of the HPPFs and the product plus 150 g of meat. Furthermore, an online survey was conducted among a convenience sample. A total of 36 enriched protein products were evaluated. The percentage of proteins in these products ranges from 10 to 88%. The contribution of the protein recommended intake was within a range of 87.4-306.6% and 66.4-232.8% (women and men, respectively), only considering the additional proteins from 150 g of meat. One hundred thirty-nine participants completed the survey; 67.6% affirmed that they had consumed HPPFs, and half consumed them without following any consumption control. Since these products are accessible to everyone in supermarkets and protein intake is generally higher than the recommended limits, regulating the mass sale of HPPFs is essential to ensure they do not lead to protein overconsumption.

RESUMEN

Introduction: To meet the food and nutritional needs of a growing population and, at the same time, guarantee natural and productive resources, food systems must undergo changes in production models and consumption patterns, adopting more sustainable diets. The recommendations of different organizations and institutions are aimed at adopting a varied and balanced dietary pattern, with a greater predominance of plant-based food and a lower presence of animal food, to improve the state of health and well-being, while reducing the environmental impact. These types of diets have important health benefits, especially if diets are well planned and foods are properly combined. However, in some stages of life (schoolchildren, adolescents, elders) and in some special physiological situations (pregnancy, athletes), special attention should be paid to the increase of certain nutritional requirements that could compromise the health status if a correct dietary planning is not carried out. Therefore, well-designed strategies should be put in place to facilitate the transition to a sustainable diet, including nutrition education programs for consumers with specific instructions on the most appropriate food choices to increase the nutritional value of the diet. In addition, in specific physiological situations, where meeting nutritional requirements may be compromised, the consumption of fortified foods and/or supplementation could be considered.

Introducción: Para atender las necesidades alimentarias y nutricionales de una población creciente y garantizar los recursos naturales y productivos, los sistemas alimentarios deben experimentar cambios adoptando dietas más sostenibles. Diferentes organismos e instituciones recomiendan patrones de dieta variada y equilibrada, con predominio de alimentos de origen vegetal y menor presencia de alimentos de origen animal, para mejorar el estado de salud y bienestar y reducir el impacto medioambiental. Este tipo de dietas presentan beneficios en la salud, sobre todo si están bien planificadas y los alimentos se combinan adecuadamente. Sin embargo, en algunas etapas de la vida (escolares, adolescentes, ancianos) y en situaciones fisiológicas especiales (embarazadas, deportistas) se debe prestar atención a los requerimientos nutricionales, que podrían verse comprometidos en caso de no llevar a cabo una correcta planificación dietética, lo que podría derivar en problemas para la salud. Por ello, para facilitar la transición de los consumidores a una dieta sostenible, se deben promover estrategias bien diseñadas que incluyan programas de educación nutricional con instrucciones específicas acerca de las elecciones y combinaciones de alimentos más adecuadas para aumentar el valor nutricional de la dieta. Además, en situaciones fisiológicas específicas en las que alcanzar los requerimientos nutricionales pudiera estar comprometido, podría considerarse el consumo de alimentos enriquecidos y/o la administración de suplementos.

RESUMEN

Introduction: Introduction: in the last decades, a significant increase in the incidence of Alzheimer's disease (AD) has been observed. Currently, there are no effective pharmacological treatments available, which makes preventive measures particularly important. Objective: to analyze the available scientific evidence on nutritional and dietary factors and their association with AD prevention. Methods: a review of nutritional and dietary factors related to the prevention of AD was conducted. Results: several dietary components have been positively associated with AD prevention, including intake of complex carbohydrates, fiber, omega-3, plant-based proteins, vitamins (folates, choline, vitamin D, C, B6 and B9), zinc, some bioactive compounds such as flavonols and probiotics. Following the Mediterranean, Dietary Approaches to Stop Hypertension (DASH) y Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diets has been associated with a lower risk of developing the disease. Conclusion: nutrition may have a protective role against AD, although further studies are needed in this regard.

RESUMEN

Introduction: The number of people following plant-based diets to a greater or lesser degree is increasing, but the more restrictive a diet, the greater the risk of nutritional deficiencies. The childhood stage is a stage of great physical and maturational growth, therefore, nutritional deficiencies at this stage can have serious and sometimes permanent consequences. People who follow restrictive diets of any kind, such as plant-based diets, should receive support from specialized staff to ensure that their diets are varied and balanced, as is desirable in any case.

Introducción: Está aumentando el número de personas que siguen dietas basadas en vegetales en mayor o menor grado, pero cuanto más restrictiva es una dieta, más riesgos existen de presentar deficiencias nutricionales. La etapa infantil es una etapa de gran crecimiento físico y madurativo, por ello, las deficiencias nutricionales en esta etapa pueden acarrear consecuencias graves y, en ocasiones, permanentes. Las personas que siguen dietas restrictivas de cualquier tipo, como son las dietas basadas en vegetales, deben recibir apoyo de personal especializado para conseguir que sus dietas sean variadas y equilibradas, como es deseable en cualquier caso.

RESUMEN

Introduction: Introduction: dysphagia is classified under "symptoms and signs involving the digestive system and abdomen" in the International Classification of Diseases (ICD-10, code R13). It is defined as obstruction in the region of the pharynx, sternum or xiphoid because of obstruction of the passage of food from the mouth to the stomach or cardia, and has become one of the most important causes affecting the adequate intake of energy and nutrients. An optimal dietary and nutritional approach plays a crucial role in the management of dysphagia. The main goal of such an approach is to ensure safe and sufficient nutrition to prevent malnutrition and complications associated with dysphagia. Objectives: to establish an action protocol for an effective dietary and nutritional approach in patients with dysphagia based on the existing scientific evidence. Methods: a review of the scientific literature on the dietary-nutritional approach to dysphagia was carried out. Results: the dietary and nutritional approach in patients with dysphagia requires a multidisciplinary and personalized approach and is essential to improve the quality of life of patients with dysphagia. Through the implementation of an evidence-based action protocol, it is possible to guarantee preventing aspiration and ensuring safe swallowing and modification of textures of different foods (thus promoting adequate intake of nutrients and fluids to avoid malnutrition and dehydration). Conclusion: adequate and protocolized management, from a dietary and nutritional point of view, can have a significant impact on the quality of life of patients, improving their well-being and preventing complications associated with this condition.

Introducción: Introducción: la disfagia se clasifica dentro de los "síntomas y signos que involucran el sistema digestivo y el abdomen" en la Clasificación Internacional de Enfermedades (CIE-10, código R13). Dicho síntoma produce en la región de la faringe, el esternón o el xifoides como resultado de la obstrucción del paso de alimentos de la boca al estómago o al cardias, y se ha convertido en una de las causas más importantes que afecta a la ingesta adecuada de energía y nutrientes. Un abordaje dietético y nutricional óptimo desempeña un papel crucial en el manejo de la disfagia. El objetivo principal de dicho abordaje es garantizar una alimentación segura y suficiente para prevenir la desnutrición y las complicaciones asociadas a la disfagia. Objetivos: establecer un protocolo de actuación para realizar, de forma eficaz, el abordaje dietético y nutricional en pacientes con disfagia en base a la evidencia científica existente. Métodos: se llevó a cabo una revisión de la literatura científica sobre el abordaje dietético-nutricional de la disfagia. Resultados: el abordaje dietético y nutricional en pacientes con disfagia requiere un enfoque multidisciplinar y personalizado, y es fundamental para mejorar la calidad de vida de los pacientes con disfagia. A través de la implementación del protocolo de actuación basado en la evidencia, se puede garantizar: prevenir la aspiración y asegurar una deglución segura y, modificación de texturas de los diferentes alimentos (promoviendo de esta forma la ingesta adecuada de nutrientes y líquidos para evitar la desnutrición y la deshidratación). Conclusión: un manejo adecuado y protocolizado, desde el punto de vista dietético y nutricional, puede llegar a tener un impacto significativo en la calidad de vida de los pacientes, mejorando su bienestar y previniendo complicaciones asociadas a esta condición.

RESUMEN

Introduction: Being more active, being less sedentary, and sleeping enough are associated with adequate body weight and adiposity in children. However, few researchers have analyzed these different lifestyle behaviors and the adherence to 24 h movement guidelines with respect to insulin resistance (IR) at school age. Therefore, we aimed to analyse the association between the adherence to 24 h movement guidelines (physical activity, sedentary time, sleep) and IR in Spanish schoolchildren. Methods: A cross-sectional study of 839 children (8-13 years, 51.1% girls) were studied. Anthropometric, biochemical, and lifestyle behavioral data were collected. IR was defined as HOMA-IR>3.16. Compliance with the 24 h movement guidelines were defined as ≥60 min/day of moderate and/or vigorous physical activity, < 120 min/day of screen time, and 9-11 h/day of sleep time. Associations between adherence to the 24 h movement guidelines and IR were performed by multivariate logistic regression analyses. Results: The IR in our sample was 5.0%, being higher in girls. Compliance with physical activity or screen time, but not with sleep recommendations, was associated with lower fasting glucose, fasting insulin, and HOMA-IR values. A low adherence to 24 h movement guidelines was associated with a higher risk of IR (odds ratio (95% CI): 2.150 [1.089-4.247]), especially in girls (odds ratio (95% CI): 2.800 [1.180-6.645]). Conclusion: Higher physical activity levels and lower screen times were associated with a lower risk of IR in schoolchildren, underlining the importance of adhering to as many healthy lifestyle recommendations as possible.

RESUMEN

This study analyzes the quality and reliability of videos related to nutrition and cancer on YouTube. STUDY DESIGN: An observational, retrospective, cross-sectional, time-limited study analyzing activity on the social network YouTube was proposed. METHODS: The information from the videos was extracted through an API search tool, using the NodeXL software. The criteria to select the videos on YouTube were the keywords "real food", "realfood", and "cancer" and the hashtags #realfood and #cancer were present, videos in English and videos available on 1 December 2022. RESULTS: The DISCERN value in the total number of videos viewed was 2.25 (±0.88) points, indicating low reliability. The videos uploaded by HRU represented only 20.8%. Videos suggesting that the use of foods defined as "real food" could cure cancer without the intervention of any other treatment accounted for 12.5%. Videos that provided external links to scientific/technical evidence verifying the information represented only 13.89% of the total number of videos. Of these videos, 70% corresponded to HRU. The DISCERN value for videos from HRU users was 3.05 (0.88), a value that reflects a good reliability of videos from these users. CONCLUSIONS: This study provides information on the content and quality of the videos that we can find on YouTube. We found videos of non-health users who do not base their content on any scientific evidence, with the danger that this entails for the population, but it also highlights that the videos published by HRU have greater reliability and quality, being better perceived by the population, so it is important to encourage healthcare professionals and health institutions to share verified information on YouTube.

RESUMEN

BACKGROUND: The aims of this study were to analyse the effect of creatine supplementation on the performance improvement in a bench pressing (BP) strength test of muscle failure and to evaluate muscle fatigue and metabolic stress 20 min after the exercise. METHODS: Fifty young and healthy individuals were randomly assigned to a creatine group (n = 25) or a placebo group (n = 25). Three exercise sessions were carried out, with one week of rest between them. In the first week, a progressive load BP test was performed until the individuals reached the one repetition maximum (1RM) in order to for us obtain the load-to-velocity ratio of each participant. In the second week, the participants conducted a three-set BP exercise protocol against 70% 1RM, where they performed the maximum number of repetitions (MNR) until muscle failure occurred, with two minutes of rest between the sets. After one week, and following a supplementation period of 7 days, where half of the participants consumed 0.3 g·kg-1·day-1 of creatine monohydrate (CR) and the other half consumed 0.3 g·kg-1·day-1 of placebo (PLA, maltodextrin), the protocol from the second week was repeated. After each set, and up to 20 min after finishing the exercise, the blood lactate concentrations and mean propulsive velocity (MPV) at 1 m·s-1 were measured. RESULTS: The CR group performed a significantly higher number of repetitions in Set 1 (CR = 14.8 repetitions, PLA = 13.6 repetitions, p = 0.006) and Set 2 (CR = 8 repetitions, PLA = 6.7 repetitions, p = 0.006) after supplementation, whereas no significant differences were seen in Set 3 (CR = 5.3 repetitions, PLA = 4.7 repetitions, p = 0.176). However, there was a significant increase in blood lactate at minute 10 (p = 0.003), minute 15 (p = 0.020), and minute 20 (p = 0.015) after the exercise in the post-supplementation period. Similarly, a significant increase was observed in the MPV at 1 m·s-1 in the CR group with respect to the PLA group at 10, 15, and 20 min after the exercise. CONCLUSIONS: Although the creatine supplementation improved the performance in the strength test of muscle failure, the metabolic stress and muscle fatigue values were greater during the 20 min of recovery.

RESUMEN

Background: Breakfast has traditionally been considered one of the most important meals of the day; however, there is little evidence for the influence of breakfast quality and insulin resistance (IR). This study aimed to assess the quality of breakfast in a group of schoolchildren, and its association with IR. Methods: A cross-sectional study with 852 children (8−13 years) was carried out. Fasting plasma glucose, insulin and anthropometric parameters were measured. A three-day dietary record was used to assess their diet and to calculate the Breakfast Quality Index (BQI). The sample was divided into tertiles according to the BQI (tertile 3: better breakfast quality). The homeostatic model was used to assess insulin resistance (HOMA-IR), and IR was defined as HOMA-IR > 3.16. Results: The prevalence of IR was 5.2%. The mean BQI score was 4.50 ± 1.25, and boys had lower scores than girls. Children in the BQI tertile 3 had a better global diet quality. In boys, being in the BQI tertile 3 was associated with a lower risk of IR (OR [95% CI]: 0.10 [0.01−0.77], p < 0.05). Conclusions: A higher-quality breakfast was associated with better overall diet quality and a lower risk of IR, especially in boys.

RESUMEN

Throughout history a variety of therapeutic tools have been studied as possible enhancers of sports activities. This study proposes the use of Capacitive-Resistive Electric Transfer (CRET) as a performance booster to paralympic athletes, specifically those belonging to the Spanish Paralympic swimming committee. The study was a randomized, single-blind, and observer-blind, crossover clinical trial. Six athletes were randomly assigned to three groups: one treated with CRET (A); a placebo group (B) and a control group (C). The CRET group attended a twenty-minute session before being subjected to pool trials at distances of 50 and 100 m at maximum performance. Measurements were in two dimensions: time in seconds and the Borg scale for perceived exertion. Comparisons between groups were made with respect to distance and the main variables. In the case of perceived exertion, no significant changes were observed in any of the distances; however, in the case of the time variable, a significant difference was observed between Group A vs. Personal Record at 100 m distance (76.3 ± 6.8 vs. 68.4 ± 3.3). The proposed protocol and level of hyperthermia applied suggest refusal of CRET use for the 100-m distance a few minutes before sports practice. Our analysis suggests the need to modify the presented protocol. ClinicalTrials.gov identifier under NCT number: NCT04336007.

RESUMEN

Introduction: Childhood obesity is a growing concern, because the problem affects a high percentage of children and is the source of many diseases in the present and in the future, which can lead to a decrease in life expectancy and quality of life. In order to combat the problem, it is necessary to analyze the factors associated with excess weight in childhood in order to act on them and try to curb the trend observed in recent years. Various socio-demographic aspects, as well as inactivity and sedentary lifestyle in children are factors that are associated with an increased risk of obesity and central adiposity. With great prominence in this issue, we have to highlight that the consumption of food is improvable: decrease the consumption of sugar, fat and sodium, and above all increase the consumption of fruits, vegetables, whole grains, fish, dairy is associated with lower obesity and central obesity in children. There is no single responsible for the problem and the interaction between healthy behaviors increases the chances of success in the fight against childhood obesity, which should be considered when planning nutritional education campaigns. Many aspects of the diet and lifestyle of the child population must be improved, perhaps now more emphasis is being placed on restrictive guidelines. Of course, it is desirable to reduce the consumption of sweets and snacks, but messages aimed at increasing the consumption of vegetables, fruits, whole grains and approximating the diet to the theoretical ideal can be prioritized. Constructive guidelines should stand out from restrictive ones.

Introducción: La obesidad infantil es objeto de preocupación creciente, porque el problema afecta a un elevado porcentaje de niños y es el origen de numerosas enfermedades en el presente y en el futuro, pudiendo condicionar un descenso en la esperanza y calidad de vida. Para combatir el problema es necesario analizar los factores que se asocian con el exceso de peso en la infancia para actuar sobre ellos e intentar frenar la tendencia observada en los últimos años. Diversos aspectos sociodemográficos, así como la inactividad y el sedentarismo de los niños son factores que se asocian con mayor riesgo de padecimiento de obesidad y adiposidad central. Con gran protagonismo en este tema debe destacarse que el consumo de alimentos es mejorable: disminuir el consumo de azúcar, grasa y sodio, y sobre todo aumentar el consumo de frutas, verduras, cereales integrales, pescado, lácteos se asocia con menor padecimiento de obesidad y obesidad central en los niños. Pero no hay un único responsable del problema y la interacción entre conductas saludables aumenta las posibilidades de éxito en la lucha contra la obesidad infantil, lo que debe ser considerado al planificar campañas de educación nutricional. Se deben mejorar numerosos aspectos de la alimentación y estilo de vida de la población infantil, quizá en este momento se hace más hincapié en pautas restrictivas, aunque es muy conveniente reducir el consumo de dulces y snacks, resulta muy deseable y quizá prioritario el aumentar el consumo de verduras, hortalizas, frutas, cereales integrales y aproximar la dieta al ideal teórico. Las pautas constructivas deberían destacar respecto a las restrictivas.

RESUMEN

Introduction: Celiac disease is the most common chronic intestinal disease. It affects approximately 1 % of the world population, affects all age groups and has symptoms both digestive and extra-digestive. The treatment of celiac disease is based on the strict withdrawal of gluten from the diet. This treatment supposes the improvement of symptoms and histology and the reduction of long-term comorbidities. People with celiac disease often follow diets that are far from the theoretical ideal, so they must be supervised and guided to achieve gluten-free diets that are also varied and balanced. In these patients it is important to avoid gluten consumption, but also to achieve an adequate supply of nutrients. However, their health problems, together with the limitations they must introduce in the diet make it more difficult to achieve a correct diet, so the group deserves special nutritional monitoring and surveillance.

Introducción: La enfermedad celíaca es la enfermedad crónica intestinal más frecuente que existe. Afecta aproximadamente al 1 % de la población mundial, a todos los grupos de edad y tiene síntomas de presentación tanto digestivos como extradigestivos. El tratamiento de la enfermedad celíaca se basa en la retirada estricta del gluten de la dieta. Este tratamiento supone la mejora de los síntomas y de la histología y la disminución de comorbilidades a largo plazo. Las personas con enfermedad celíaca realizan con frecuencia dietas alejadas del ideal teórico, por lo que deben ser supervisadas y orientadas para lograr dietas sin gluten y también variadas y equilibradas. En estos pacientes es importante evitar el consumo de gluten, pero también lograr un aporte adecuado de nutrientes y su problemática sanitaria, junto con las limitaciones que deben introducir en la dieta, hacen más difícil lograr una alimentación correcta, por lo que el colectivo merece una vigilancia y un control nutricional especiales.
