RESUMEN
Taste disorders (TDs) are common among systemically treated cancer patients and negatively impact their nutritional status and quality of life. The novel food approved by the European Commission (EFSA), dried miracle berries (DMB), contains the natural taste-modifying protein miraculin. DMB, also available as a supplement, has emerged as a possible alternative treatment for TDs. The present study aimed to evaluate the efficacy and safety of habitual DMB consumption in malnourished cancer patients undergoing active treatment. An exploratory clinical trial was carried out in which 31 cancer patients were randomized into three arms [standard dose of DMB (150 mg DMB/tablet), high dose of DMB (300 mg DMB/tablet) or placebo (300 mg freeze-dried strawberry)] for three months. Patients consumed a DMB tablet or placebo daily before each main meal (breakfast, lunch, and dinner). Throughout the five main visits, electrochemical taste perception, nutritional status, dietary intake, quality of life and the fatty acid profile of erythrocytes were evaluated. Patients consuming a standard dose of DMB exhibited improved taste acuity over time (% change right/left side: -52.8 ± 38.5/-58.7 ± 69.2%) and salty taste perception (2.29 ± 1.25 vs. high dose: 2.17 ± 1.84 vs. placebo: 1.57 ± 1.51 points, p < 0.05). They also had higher energy intake (p = 0.075) and covered better energy expenditure (107 ± 19%). The quality of life evaluated by symptom scales improved in patients receiving the standard dose of DMB (constipation, p = 0.048). The levels of arachidonic (13.1 ± 1.8; 14.0 ± 2.8, 12.0 ± 2.0%; p = 0.004) and docosahexaenoic (4.4 ± 1.7; 4.1 ± 1.0; 3.9 ± 1.6%; p = 0.014) acids in erythrocytes increased over time after DMB intake. The standard dose of DMB increased fat-free mass vs. placebo (47.4 ± 9.3 vs. 44.1 ± 4.7 kg, p = 0.007). Importantly, habitual patients with DMB did not experience any adverse events, and metabolic parameters remained stable and within normal ranges. In conclusion, habitual consumption of a standard 150 mg dose of DMB improves electrochemical food perception, nutritional status (energy intake, fat quantity and quality, fat-free mass), and quality of life in malnourished cancer patients receiving antineoplastic treatment. Additionally, DMB consumption appears to be safe, with no changes in major biochemical parameters associated with health status. Clinical trial registered (NCT05486260).

Introduction: Breast cancer is the most prevalent tumor in women, ranking first in incidence and mortality in many countries. Although the causes of breast cancer are complex and multifactorial, nutritional factors and those related to nutritional status play an important role in the development of the disease. In this way, factors that increase breast cancer risk have been identified, such as weight gain, the amount of adipose tissue, waist circumference, alcohol consumption or the consumption of red meat and processed meat, while other factors have been identified that reduce the risk, such as eating fruits and vegetables. Nutritional factors or factors that depend on the state of nutrition are modifiable and preventable, so they must be considered when designing effective prevention programs.
Introducción: El cáncer de mama es el tumor más prevalente en las mujeres y ocupa el primer lugar en incidencia y en mortalidad en muchos países. Si bien las causas del cáncer de mama son complejas y multifactoriales, los factores nutricionales y aquellos relacionados con el estado nutricional juegan un papel importante en el desarrollo de la enfermedad. De esta forma, se han identificado algunos factores que aumentan su riesgo, como el aumento de peso, la cantidad de tejido adiposo, la circunferencia de cintura, el consumo de alcohol, etc., o bien, que lo reducen, como el consumo de frutas y verduras. Los factores nutricionales o que dependen del estado de nutrición son modificables y prevenibles, por lo que deben tenerse en cuenta al diseñar programas de prevención eficaces.

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.

Introduction: Anorexia nervosa (AN) is a psychiatric disease with a high prevalence and comorbidities, characterized by a low response rate to treatment. It is considered as a multifactorial disease. In recent years, the focus has been placed on the presence of intestinal dysbiosis and its possible involvement as a causal factor as well as an alternative treatment. The objective of this work has been to review the current state of knowledge of alterations in the intestinal microbiota identified in patients with AN and the possibility of using probiotics as a therapeutic alternative. Significant changes in the diversity of species associated with weight loss have been described that could favor the perpetuation of the disorder, and that would explain many of the nutritional, gastrointestinal, psychological, and cognitive alterations present in these patients. The use of probiotics, still little studied in patients with AN, sheds some light on this matter to improve the treatment response, always hand in hand with conventional treatments.
Introducción: La anorexia nerviosa (AN) es una enfermedad psiquiátrica, con elevada prevalencia y comorbilidades, caracterizada por una baja tasa de respuesta al tratamiento. Se considera una enfermedad multifactorial. En los últimos años se ha puesto el foco en la presencia de disbiosis intestinal y su posible implicación como factor causal, así como alternativa de tratamiento. El objetivo de este trabajo ha sido revisar el estado actual del conocimiento de las alteraciones en la microbiota intestinal identificadas en pacientes con AN y la posibilidad del uso de probióticos como alternativa terapéutica. Se han descrito importantes cambios en la diversidad de las especies asociadas a la pérdida de peso que podrían contribuir a perpetuar el trastorno y que explicarían muchas de las alteraciones nutricionales, gastrointestinales, psicológicas y cognitivas presentes en estos pacientes. El uso de probióticos, poco estudiado aún en pacientes con AN, abre una nueva ventana para mejorar la respuesta, siempre de la mano de los tratamientos convencionales.

Taste disorders are common among cancer patients undergoing chemotherapy, with a prevalence ranging from 20% to 86%, persisting throughout treatment. This condition leads to reduced food consumption, increasing the risk of malnutrition. Malnutrition is associated not only with worse treatment efficacy and poor disease prognosis but also with reduced functional status and quality of life. The fruit of Synsepalum dulcificum (Daniell), commonly known as miracle berry or miracle fruit, contains miraculin, a taste-modifying protein with profound effects on taste perception. The CLINMIR Protocol is a triple-blind, randomized, placebo-controlled clinical trial designed to evaluate the regular consumption of a food supplement containing a miraculin-based novel food, dried miracle berry (DMB), on the taste perception (measured through electrogustometry) and nutritional status (evaluated through the GLIM Criteria) of malnourished cancer patients under active antineoplastic treatment. To this end, a pilot study was designed with 30 randomized patients divided into three study arms (150 mg DMB + 150 mg freeze-dried strawberries, 300 mg DMB, or placebo) for three months. Throughout the five main visits, an exhaustive assessment of different parameters susceptible to improvement through regular consumption of the miraculin-based food supplement will be conducted, including electrical and chemical taste perception, smell perception, nutritional and morphofunctional assessment, diet, quality of life, the fatty acid profile of erythrocytes, levels of inflammatory and cancer-associated cytokines, oxidative stress, antioxidant defense system, plasma metabolomics, and saliva and stool microbiota. The primary anticipated result is that malnourished cancer patients with taste distortion who consume the miraculin-based food supplement will report an improvement in food taste perception. This improvement translates into increased food intake, thereby ameliorating their nutritional status and mitigating associated risks. Additionally, the study aims to pinpoint the optimal dosage that provides maximal benefits. The protocol adheres to the SPIRIT 2013 Statement, which provides evidence-based recommendations and is widely endorsed as an international standard for trial protocols. The clinical trial protocol has been registered at the platform for Clinical Trials (NCT05486260).

Introduction: Introduction: oral nutritional supplements (ONS) are nutritional therapies used to treat malnutrition in cancer patients, therefore, innovation in these treatments, from nutrients to sensory quality, is essential to ensure their consumption. Objectives: to evaluate the organoleptic characteristic of different prototypes of oral nutritional supplements specifically designed for cancer patients. Method: cross-sectional, randomized, double-blind pilot clinical study in patients with any type of cancer, with or without oncological treatment, who tasted five ONS prototypes with different flavors (brownie, tropical, pineapple, tomato and ham) and different sensory qualities in order to evaluate their organoleptic characteristics (color, smell, taste, residual taste, texture and density) through a specific questionnaire. Results: thirty patients aged 67.5 ± 11.2 years and body mass index (BMI) of 22.3 ± 3.52 kg/m2 were evaluated. The most prevalent tumors were head and neck (30 %), pancreas (20 %) and colon (17 %); 65 % of the patients had lost ≥ 10 % of their body weight in six months. The best rated supplements by the cancer population were those with brownie flavor (23.67 ± 3.91 points) and tropical (20.33 ± 3.37 points), while the least valued were tomato (16.33 ± 5.44 points) and ham flavor (13.97 ± 4.64 points). Conclusions: cancer patients value the organoleptic characteristics of ONS with sweet flavors, such as brownie, and fruity flavors, such as tropical, much more positively. Less appreciated by these patients are those with a salty taste, such as ham and tomato flavor.
Introducción: Introducción: los suplementos nutricionales orales (SNO) son una de las terapias nutricionales más utilizadas para tratar la desnutrición en los pacientes oncológicos. Por ello, es de gran importancia contar con la innovación en estos tratamientos, desde los nutrientes hasta la calidad sensorial, para asegurar su consumo. Objetivos: evaluar las características organolépticas de diferentes prototipos de SNO diseñados específicamente para pacientes oncológicos. Métodos: estudio clínico piloto transversal, aleatorizado, cruzado y doble ciego en pacientes con cualquier tipo de cáncer, con o sin tratamiento oncológico, a los que se les realizó una cata de cinco prototipos de SNO con distintos sabores (brownie, tropical, piña, tomate y jamón) y distintas cualidades sensoriales para evaluar sus características organolépticas (color, olor, sabor, gusto residual, textura y densidad) a través de un cuestionario específico. Resultados: treinta pacientes de 67,5 ± 11,2 años y con un índice de masa corporal (IMC) de 22,3 ± 3,52 kg/m2 fueron evaluados. Los tumores más prevalentes fueron cabeza y cuello (30 %), páncreas (20 %) y colorrectal (17 %). El 65 % de los pacientes había perdido ≥ 10 % del peso corporal en seis meses. Los SNO mejor valorados fueron los sabores brownie (23,67 ± 3,91 puntos) y tropical (20,33 ± 3,37 puntos) mientras que los menos valorados fueron los SNO con sabor tomate (16,33 ± 5,44 puntos) y jamón (13,97 ± 4,64 puntos). Conclusión: los pacientes oncológicos valoran de forma mucho más positiva las características organolépticas de los SNO con sabores dulces, como el brownie, y los sabores afrutados, como el tropical. Menos apreciados por este colectivo son aquellos con un sabor salado, como el sabor jamón y tomate.

Introduction: European Union represents a tenth of the world population, however, it has a quarter of the cancer cases in the world. Without strong action, it is estimated that by 2035 cancer cases will increase by almost 25 %, making this disease the main cause of death. Therefore, the aim of this study is to know the diet and lifestyle guidelines associated to cancer prevention. A literature review has been carried out on the diet and lifestyle guidelines related to a reduction in cancer risk. Strategies to reduce cancer risk include maintaining a healthy weight, being physically active, consuming a diet rich in whole grains, fruits, non-starchy vegetables, and legumes, limit processed and fast food, limit consumption of red meat and eat little, if any, processed meats, drink mostly water and limit the consumption of sugar sweetened drinks, finally reduce, or do not consume alcohol. Prevention is an effective tool to reduce cancer risk. Adequate diet and healthy lifestyle habits can reduce cancer risk as well as other non-communicable diseases and can even have environmental benefits.
Introducción: La Unión Europea representa una décima parte de la población mundial, pero tiene un cuarto de los casos de cáncer de todo el mundo. Sin una acción contundente, se estima que en 2035 los casos de cáncer aumentarán casi un 25 %, lo que convertirá a esta enfermedad en la principal causa de muerte. Por ello, el objetivo del presente estudio es conocer las pautas de alimentación y de estilo de vida que influyen en la prevención del cáncer. Para ello se ha realizado una revisión bibliográfica de las pautas de alimentación y de los principales estilos de vida que se relacionan con una reducción del riesgo de padecer cáncer. Entre las estrategias para reducir el riesgo de cáncer se encuentran el mantenimiento de un peso saludable a lo largo de toda la vida, ser físicamente activo, consumir una dieta rica en cereales integrales, frutas, verduras no almidonadas y legumbres, limitar el consumo de alimentos procesados y de comida rápida, limitar el consumo de carne roja y consumir poco o nada de carnes procesadas, consumir principalmente agua y limitar el consumo de bebidas azucaradas, y por último, reducir el consumo de alcohol o no consumirlo. La prevención es una herramienta eficaz para reducir el riesgo de padecer cáncer. Una adecuada alimentación y hábitos de vida saludables reducirán el riesgo de padecer cáncer en el futuro, así como otras enfermedades no transmisibles e, incluso, beneficios medioambientales.

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.

Hydroxytyrosol (HT) and punicalagin (PC) exert cardioprotective and antiatherosclerotic effects. This study evaluated the effect of an oral supplement containing HT and PC (SAx) on dyslipidemia in an adult population. A randomized, double-blind, controlled, crossover trial was conducted over a 20-week period. SAx significantly reduced the plasma levels of triglycerides (TG) in subjects with hypertriglyceridemia (≥150 mg/dL) (from 200.67 ± 51.38 to 155.33 ± 42.44 mg/dL; p < 0.05), while no such effects were observed in these subjects after the placebo. SAx also significantly decreased the plasma levels of low-density lipoprotein cholesterol (LDL-C) in subjects with high plasma levels of LDL-C (≥160 mg/dL) (from 179.13 ± 16.18 to 162.93 ± 27.05 mg/dL; p < 0.01), while no such positive effect was observed with the placebo. In addition, the placebo significantly reduced the plasma levels of high-density lipoprotein cholesterol (HDL-C) in the total population (from 64.49 ± 12.65 to 62.55 ± 11.57 mg/dL; p < 0.05), while SAx significantly increased the plasma levels of HDL-C in subjects with low plasma levels of HDL-C (<50 mg/dL) (from 44.25 ± 3.99 to 48.00 ± 7.27 mg/dL; p < 0.05). In conclusion, the supplement containing HT and PC exerted antiatherosclerotic and cardio-protective effects by considerably improving dyslipidemia in an adult population, without co-adjuvant treatment or adverse effects.

Introduction: Introduction: excess weight represents a public health problem due to its associated risk factors. A sedentary lifestyle, an inadequate diet or a decrease in the feeling of satiety are some of the causes. Objetives: to evaluate the satiating properties of the consumption of a functional Iberian broth enriched with phospho-fructooligosaccharides (FOS) in healthy people through the plasma concentration of hormones involved in appetite. Material and method: acute, crossover, randomized, double-blind and controlled nutritional clinical trial carried out in 18 randomized participants in two treatment sequences (functional broth (CF), composed of 5.6 g POS/100 g and control broth (CC), with 0.4 g of maltodextrin/100 g) with 14 days of washing in between. Satiety-related parameters (glucose, insulin, leptin, ghrelin, GLP-1, PYY) and visual analog scales (VAS) were measured. Results: the percentage of body fat decreased in those who took the CF (-0.15 ± 0.32 vs 0.09 ± 0.52) (p < 0.05). Leptin concentration was higher with CF (p < 0.001), which was shown at time points -30 (p < 0.001), 0 (p < 0.001), 30 (p = 0.026) and 120 (p = 0.049) when compared to CC. The areas under the curve (AUC) for GLP-1 (p = 0.0033) and PYY (p = 0.022) were higher for CF as compared to CC. Conclusions: consumption of an Iberian broth enriched with POS improves the plasma concentration of hormones involved in the control of satiety, and reduces the amount of body fat. This result could have beneficial effects for the prevention and treatment of overweight.
Introducción: Introducción: el exceso de peso representa un problema de salud pública debido a los factores de riesgo asociados. El sedentarismo, una alimentación inadecuada o una disminución de la sensación de saciedad son algunas de sus causas. Objetivos: evaluar las propiedades saciantes del consumo de un caldo ibérico funcional enriquecido con fosfofructooligosacáridos (FOS) en personas sanas a través de la concentración plasmática de las hormonas involucradas en el apetito. Material y métodos: ensayo clínico nutricional, agudo, cruzado, aleatorizado, doble ciego y controlado, llevado a cabo en 18 participantes aleatorizados en dos secuencias de tratamiento (caldo funcional (CF) compuesto de 5,6 g de FOS/100 g y caldo de control (CC), con 0,4 g de maltodextrina/100 g) con 14 días de lavado entre ellas. Se midieron parámetros relacionados con la saciedad (glucosa, insulina, leptina, ghrelina, GLP-1, PYY) y escalas analógicas visuales (EAV). Resultados: el porcentaje de grasa corporal disminuyó en los que tomaron el CF (-0,15 ± 0,32 vs. 0,09 ± 0,52) (p < 0,05). La concentración de leptina fue superior con el CF (p < 0,001), mostrándose dicho aumento en los tiempos -30 (p < 0,001), 0 (p < 0,001), 30 (p = 0,026) y 120 (p = 0,049) con respecto al CC. Las áreas bajo la curva (AUC) de GLP-1 (p = 0,0033) y PYY (p = 0,022) fueron superiores con el CF en comparación con el CC. Conclusión: el consumo de un caldo ibérico enriquecido con FOS mejora la concentración plasmática de las hormonas involucradas en el control de la saciedad y reduce la cantidad de grasa corporal. Dichos resultados podrían tener efectos beneficiosos para la prevención y el tratamiento del exceso de peso corporal.

INTRODUCTION: Objectives: Canary Islands bananas represent the only native cultivar of Musa spp. present in Spanish territory. Since 2013, it has the Protected Geographical Indication label, which confers an additional value to this fruit. Bananas from the Canary Islands have certain organoleptic properties that make them stand out from among other commonly consumed Musa spp. However, to date, no studies have been reported including an extended nutritional composition of this product. Methods: the present work shows the main nutritional components of bananas from the Canary Islands as determined by different analytical techniques (mainly liquid chromatography, spectroscopy, spectrophotometry, and polarimetry) when at their best in terms of ripeness (grade 6). Moreover, potential nutrition claims relating to their composition were proposed using the current legislation. Results: the fruit's remarkable content, edible portion, in vitamin B6 (0.52 g/100 g), dietary fiber (2.22 g/100 g), potassium (419.9 mg/100 g), and vitamin C (12.35 mg/100 g) should be highlighted. Additionally, these components could appear on nutritional labeling as claims, according to current European regulations. Conclusions: a daily consumption of one Canary Islands banana contributes to the recommended dietary intake of vitamin B6, vitamin C, potassium, and dietary fiber. The high nutritional value of this fruit enhances its presence in the Mediterranean eating pattern, being remarkable as a local product with excellent nutritional properties.
INTRODUCCIÓN: Objetivos: el plátano de Canarias es el único fruto del género Musa que se produce en territorio español. Desde el año 2013 se cataloga como un alimento con Indicación Geográfica Protegida (IGP). El plátano de Canarias presenta características propias a nivel organoléptico que lo diferencian de otros frutos de consumo del mismo género como la banana. Sin embargo, hasta la fecha no se habían realizado estudios detallados sobre su composición nutricional y las posibles declaraciones nutricionales derivadas de su composición. Métodos: en el presente trabajo se muestran los resultados del análisis bromatológico del plátano de Canarias, realizado a través de distintas técnicas (cromatografía liquida, espectroscopia, espectrofotometría y polarimetría) en un estado óptimo de maduración del fruto (estadio 6). Adicionalmente, se hizo uso de la legislación vigente concerniente a las declaraciones de la composición nutricional de alimentos (Reglamento N.º 1169/2011) para esclarecer aquellas atribuibles al plátano. Resultados: el plátano de Canarias es un alimento con alto contenido por porción comestible en vitamina B6 (0,52 g/100 g) y fuente de potasio (419,9 mg/100 g), fibra dietética total (2,22 g/100 g) y vitamina C (12,35 mg/100 g) de manera natural, de acuerdo con la legislación vigente en materia de etiquetado alimentario. Conclusiones: la ingesta diaria de un plátano de Canarias contribuye a alcanzar el consumo recomendado de tres piezas de fruta al día, aportando unos valores de referencia de nutrientes (VRN) óptimos de vitaminas (B6, C), minerales (potasio) y fibra dietética, con el consiguiente valor añadido a nivel nutricional que pone de manifiesto su importancia como alimento de producción local y su incorporación como tal en el contexto de una dieta saludable.

INTRODUCTION: Introduction: breast cancer is the most common invasive cancer among women in developed countries. At diagnosis, approximately 70 % of women are overweight, and the additional weight gain that can result from the ensuing treatments has been associated with cancer recurrence and progression. Objectives: the main objective was to compare the effect of only a nutritional intervention (CG) with a nutrition education program (nutritional intervention, nutrition education, and physical activity) (IG) for 1 year. Methods: a total of 65 women with breast cancer who had been evaluated at the Clinical Nutrition Department, La Paz University Hospital, Madrid, Spain were recruited into 2 groups: a control group (CG) and an intervention group (IG). Results: the IG showed a significant reduction in body weight (-1.87 ± 3.41 vs. 1.48 ± 2.01 kg, p < 0.05), BMI (-0.61 ± 1.40 vs. 0.65 ± 0.88 kg/m2, p < 0.05), total cholesterol (-32.92 ± 38.45 vs. -3.23 ± 39.73 mg/dl, p < 0.05), and low-density lipoprotein cholesterol (-35.29 ± 27.50 vs. 6.33 ± 40.70 mg/dl, p < 0.05). Both groups were shown to be more conscious of the importance of physical activity, with increased consumption of grains, fruits, oily fish, and dairy. Conclusions: dietary interventions and physical activity were shown to be important to achieving several physical and physiological benefits that could reduce some risk factors associated with breast cancer recurrence and progression.
INTRODUCCIÓN: Introducción: el cáncer de mama es el cáncer invasivo más común entre las mujeres de los países desarrollados. En el momento del diagnóstico, aproximadamente el 70 % de las mujeres tienen sobrepeso, y el aumento de peso adicional que puede resultar de los tratamientos subsiguientes se ha asociado con la recurrencia y progresión de la enfermedad. Objetivos: el objetivo principal del estudio fue comparar el efecto de solo una intervención nutricional (GC) con un programa integral de educación nutricional (intervención y educación nutricional y actividad física) (IG) durante 1 año. Métodos: un total de 65 mujeres con cáncer de mama previamente evaluadas en la Unidad de Nutrición Clínica y Dietética del Hospital Universitario La Paz, Madrid, España, fueron reclutadas y divididas en 2 grupos: grupo de control (GC) y grupo de intervención (GI). Resultados: el GI mostró una reducción significativa del peso corporal (-1,87 ± 3,41 vs. 1,48 ± 2,01 kg, p < 0,05), IMC (-0,61 ± 1,40 vs. 0,65 ± 0,88 kg/m2, p < 0,05), colesterol total (-32,92 ± 38,45 vs. -3,23 ± 39,73 mg/dl, p < 0,05) y colesterol unido a lipoproteínas de baja densidad (LDL) (-35,29 ± 27,50 vs. 6,33 ± 40,70 mg/dl, p < 0,05). Al finalizar el estudio, ambos grupos fueron más conscientes de la importancia de la actividad física y demostraron consumir una cantidad más elevada de cereales, frutas, pescado azul y lácteos. Conclusiones: las intervenciones dietéticas junto con la práctica de actividad física son importantes para lograr beneficios físicos y fisiológicos que podrían reducir algunos factores de riesgo asociados con la recurrencia y progresión del cáncer de mama.

PURPOSE: The aim of this study was to evaluate the hypocholesterolemic, immune- and microbiota-modulatory effect of a mushroom extract in hypercholesterolemic subjects. METHODS: A randomized, controlled, double-blind, and parallel clinical trial was carried out with subjects from 18 to 65 years old (n = 52) with untreated mild hypercholesterolemia. Volunteers consumed a ß-D-glucan-enriched (BGE) mixture (10.4 g/day) obtained from shiitake mushrooms (Lentinula edodes) ensuring a 3.5 g/day of fungal ß-D-glucans or a placebo incorporated in three different commercial creams. RESULTS: This mixture showed hypocholesterolemic activities in vitro and in animal studies. After eight weeks intervention, no significant differences in lipid- or cholesterol-related parameters were found compared to placebo subjects as well as before and after the BGE mixture administration. No inflammatory or immunomodulatory responses were noticed and no changes in IL-1ß, IL-6, TNF-α or oxLDL were recorded. However, consumption of the BGE mixture was safe and managed to achieve the dietary fibre intake recommended as cardiovascular protective diet. Moreover, the BGE mixture modulated the colonic microbiota differently compared to placebo. Microbial community composition varied from before to after the intervention with several genera being positively or negatively correlated with some biomarkers related to cholesterol metabolism. CONCLUSION: These results suggested a relation between cholesterol metabolism, microbiota and BGE administration. Nevertheless, the precise significance of this differential modulation was not fully elucidated and requires further studies.

INTRODUCTION: Introduction: disease-related malnutrition (DRM) is a specific type of malnutrition caused by the inflammatory response to the underlying disease. Its prevalence worldwide varies from 30 % to 50 %, being similar in Spanish hospitals. DRE is not commonly recognized but is usually misdiagnosed and generally not treated. It is associated with an increased risk of morbidity, mortality, and costs. Nutritional societies recommend that screening be performed within the first 24 to 48 hours after admission for the early detection of malnutrition. No screening tool is universally accepted. Objectives: to evaluate the predictive validity (hospital stay, complications, readmissions and mortality) of the CONUT method as compared to SGA and NSA. Material and method: a retrospective study included in a prospective observational study of 365 hospitalized patients from July to December 2012. Results: the most frequent admission services were Internal Medicine and Oncology (30.7 % and 29.3 %). Moderate and severe risk of malnutrition: CONUT, 42.2 % and 12.1 %, SGA 25.8 % and 10.1 %, and NSA 13.7 % and 14.5 %. Malnutrition evaluated using the CONUT method was significantly related to complications (p = 0.036), readmissions (p = 0.041) and mortality (p = 0.007). The ROC curves for mortality, for all the methods evaluated, showed that CONUT is the best tool. Conclusions: CONUT is an automatic detection tool that can be used as a first step in the diagnosis risk of malnutrition. CONUT offers the advantage of being a prognostic factor for complications, readmission, and mortality.
INTRODUCCIÓN: Introducción: la desnutrición relacionada con la enfermedad (DRE) es un tipo específico de desnutrición producida por la respuesta inflamatoria de la enfermedad de base. Su prevalencia en todo el mundo varía del 30 al 50 %, siendo similar en los hospitales españoles. La DRE no se reconoce comúnmente, se diagnostica inadecuadamente y generalmente no se trata. Se asocia a un mayor riesgo de morbilidad, mortalidad y costes. Las sociedades nutricionales recomiendan que el cribado se realice en las primeras 24 a 48 horas posteriores al ingreso para la detección temprana de la desnutrición. Ninguna herramienta de cribado se acepta universalmente. Objetivos: evaluar la validez predictiva (estancia hospitalaria, complicaciones, reingresos y mortalidad) del método CONUT en comparación con la VGS y el VEN. Material y método: estudio retrospectivo incluido en un prospectivo observacional de 365 pacientes hospitalizados de julio a diciembre de 2012. Resultados: los servicios de ingreso más frecuentes fueron Medicina Interna y Oncología (30,7 % y 29,3 %). Detección de los riesgos moderado y severo de desnutrición: CONUT, 42,2 y 12,1 %; VSG, 25,8 % y 10,1 %; VEN, 13,7 y 14,5 %. La desnutrición evaluada utilizando el método CONUT se relacionó significativamente con las complicaciones (p = 0,036), los reingresos (p = 0,041) y la mortalidad (p = 0,007). Las curvas ROC de la mortalidad, para todos los métodos evaluados, mostraron que CONUT es la mejor herramienta. Conclusiones: CONUT es una herramienta de detección automática que se puede utilizar como primer paso en el diagnóstico del riesgo de desnutrición. CONUT ofrece la ventaja de ser un factor pronóstico de complicaciones, reingreso y mortalidad.

Osteoporosis is a multifactorial disease characterized by the loss of bone mass and deterioration of the internal structure of the bone, increasing the risk of fractures, and is becoming an economic and social problem. The main treatment is pharmacological, however, the population demands other therapies, such as foods with nutrients beneficial to bone health. Seventy-eight healthy menopausal women at risk of osteoporosis or untreated osteopenia were recruited for a randomized, parallel, double-blind clinical trial with two intervention groups: one group consumed a serving a day of the experimental enriched product (experimental group (EG)) and the other group (control group (CG)) consumed the same product without enrichment. The main objective was to compare the effect of consuming a dairy preparation to reconstitute, similar to yogurt when prepared, enriched in calcium, vitamin D, vitamin K, vitamin C, zinc, magnesium, L-leucine and probiotic (Lactobacillus plantarum 3547) on bone metabolism markers for 24 weeks. The EG showed a significantly increased bone mass compared to the CG (0.01 ± 0.03 vs. -0.01 ± 0.03 kg; p < 0.05). In addition, the EG maintained their bone mineral density (BMD) compared to the CG, whose BMD significantly decreased at the end of the study. For biochemical markers, the EG significantly increased the serum levels of the N-terminal propeptide of type I collagen (P1NP) bone formation marker (13.19 ± 25.17 vs. -4.21 ± 15.62 ng/mL; p < 0.05), and decreased the carbo-terminal telopeptide of type I collagen (CTx) bone resorption marker compared to the CG (-0.05 ± 0.19 vs. 0.04 ± 0.14 ng/mL; p < 0.05). On the other hand, the EG exhibited a significantly decreased systolic and diastolic blood pressure compared to the start of the study. Finally, the EG significantly increased their dietary calcium and vitamin D intake compared to the CG. In conclusion, the regular consumption of a dairy product to reconstitute enriched with bioactive nutrients improves bone health markers in menopausal women at risk of osteoporosis without pharmacological treatment.

Obesity is a global public health problem. OBJECTIVE: To evaluate the effect of the regular consumption of the product Lipigo® on body weight and rebound effect on overweight/obese subjects undergoing a comprehensive weight loss program. METHODS: A randomized, parallel, double-blind, placebo-controlled clinical trial was conducted with male and female subjects presenting a BMI 25-39.9 kg/m2. All subjects underwent a comprehensive weight loss program (WLP) for 12 weeks, which included an individualized hypocaloric diet, physical activity recommendations, nutritional education seminars, and three times a day consumption of the product Lipigo® or Placebo. After-WLP, subjects continued the treatment for 9 months to assess rebound effect. Body weight (BW), BMI, and body composition were measured at the beginning and the end of the WLP, and in the follow-up. RESULTS: A total of 120 subjects (85% women) 49.0 ± 9.5 years old and with a BW of 81.57 ± 13.26 kg (BMI 31.19 ± 3.44 kg/m2) were randomized and 73 subjects finished the study. At the end of the WLP, there was a tendency toward reduced BW (p = 0.093), BMI (p = 0.063), and WC (p = 0.059) in the treated group. However, subjects with obesity type 1 (OB1) from the treated group significantly reduced body weight (-5.27 ± 2.75 vs. -3.08 ± 1.73 kg; p = 0.017) and BMI (-1.99 ± 1.08 vs. -1.09 ± 0.55 kg/m2; p = 0.01) compared with placebo. They also presented a minor rebound effect after 9 months with product consumption (-4.19 ± 3.61 vs. -1.44 ± 2.51 kg; p = 0.026), minor BMI (-1.61 ± 1.43 vs. -0.52 ± 0.96 kg/m2; p = 0.025) and tended to have less fat-mass (-3.44 ± 2.46 vs. -1.44 ± 3.29 kg; p = 0.080) compared with placebo. CONCLUSIONS: The regular consumption of the product Lipigo® promotes the reduction of body weight and reduces the rebound effect of obese people after 52 weeks (12 months), mainly in obesity type 1, who undergo a comprehensive weight loss program.

This study examines the value of a goat cheese naturally enriched in polyunsaturated fatty acids (PUFA) (n-3 PUFA and conjugated linolenic acid (CLA)) as means of improving cardiovascular and inflammatory health. Sixty-eight overweight and obese subjects (BMI ≥ 27 and <40 kg/m2), with at least two risk factors for cardiovascular disease (CVD) in a lipid panel blood tests, participated in a randomized, placebo-controlled, double-blind, parallel designed study. The subjects consumed for 12 weeks: (1) 60 g/d control goat cheese and (2) 60 g/d goat cheese naturally enriched in n-3 PUFA and CLA. Diet and physical activity were assessed. Anthropometric and dual-energy X-ray absorptiometry (DXA) tests were performed. Blood samples were collected at the beginning and at the end of the study period. Changes in health status, lifestyle and dietary habits, and daily compliance were recorded. The consumption of a PUFA-enriched goat cheese significantly increased plasma high-density lipoprotein (HDL)-cholesterol, as well as in apolipoprotein B, and it significantly decreased high-sensitivity C-reactive protein concentrations compared to the control goat cheese (p < 0.05). The significant improvement of the plasma lipid profile and inflammatory status of people with risk for CVD due to the consumption of PUFA-enriched cheese suggests a potential role of this dairy product as an alternative to develop high nutritional value food in a balanced diet comprising regular exercise.

Studies with overweight people are a priority in order to observe the effect of the timing of intervention on pre-obesity people. The aim was to compare different physical activity programs plus an individualized hypocaloric diet on body composition in overweight subjects. A randomized controlled clinical trial was carried out in overweight adults with no history of relevant illness. Primary outcome was total fat mass (TFM). Participants were allocated into four activity programs with equal intensity and volume of exercise for 22 weeks: strength training (S), endurance training (E), strength + endurance training (SE), and 'adhering to physical activity recommendations' (C). Participants followed a diet with 25% less energy (50%-55% carbohydrates, 30%-35% fat) measured by accelerometer. Variables were assessed at baseline and at the end of the intervention. Body composition was measured by dual-energy X-ray absorptiometry. One hundred nineteen from 205 subjects were randomized in the four exercise groups (S = 30/E = 30/SE = 30/C = 29) and 84 participants (36 men/48 women) ended the intervention (S = 19/E = 25/SE = 22/C = 18). At the end of the experiment, all groups except C increased their total physical activity (S = 1159 ± 1740; E = 1625 ± 1790; SE = 1699 ± 2516; C = 724 ± 1979 MET-min/week). Using an ANOVA-test, improvements were observed in body weight (S = -4.6 ± 4.5; E = -6.6 ± 4.6; SE = -8.5 ± 2.8; C = -6.1 ± 5.6 kg, p = 0.059) and TFM (S = -4.24 ± 2.02; E = -4.74 ± 2.96; SE = -6.74 ± 3.27; C = -3.94 ± 4.18%; p < 0.05). The main conclusion was that there were no adverse events. Strength and endurance training with a balanced, individualized hypocaloric diet was the most effective at reducing weight loss and fat mass in overweight subjects. Trial registration: NCT01116856.

The aim of this study was to examine whether a type of exercise favors better compliance with a prescribed diet, higher eating-related motivation, healthier diet composition or greater changes in body composition in overweight and obese subjects. One hundred and sixty-two (males n = 79), aged 18-50 years, were randomized into four intervention groups during 24 weeks: strength, endurance, combined strength + endurance and guideline-based physical activity; all in combination with a 25-30% caloric restriction diet. A food frequency questionnaire and a "3-day food and drink record" were applied pre- and post-intervention. Diet and exercise-related motivation levels were evaluated with a questionnaire developed for this study. Body composition was assessed by DXA and habitual physical activity was measured by accelerometry. Body weight, body mass index (BMI) and body fat percentage decreased and lean body mass increased after the intervention, without differences by groups. No interactions were observed between intervention groups and time; all showing a decreased in energy intake (p < 0.001). Carbohydrate and protein intakes increased, and fat intake decreased from pre- to post-intervention without significant interactions with intervention groups, BMI category or gender (p < 0.001). Diet-related motivation showed a tendency to increase from pre- to post-intervention (70.0 ± 0.5 vs 71.0 ± 0.6, p = 0.053), without significant interactions with intervention groups, BMI or gender. Regarding motivation for exercise, gender x time interactions were observed (F(1,146) = 7.452, p = 0.007): Women increased their motivation after the intervention (pre: 17.6 ± 0.3, post: 18.2 ± 0.3), while men maintained it. These findings suggest that there are no substantial effects of exercise type on energy intake, macronutrient selection or body composition changes. After a six-month weight loss program, individuals did not reduce their motivation related to diet or exercise, especially women. Individuals who initiate a long-term exercise program do not increase their energy intake in a compensatory fashion, if diet advices are included.

INTRODUCTION: Introduction: frailty and sarcopenia are prevalent conditions in older adults which diagnosis and treatment often overlap. Objective: to analyze the nutritional problematic related to frailty and sarcopenia in older adults. Methods: a literature review, about particularities of frailty and sarcopenia, diagnosis and nutritional treatment, has been carried out. Results: frailty is a geriatric syndrome that can be identified by at least three of the following criteria: weight loss, exhaustion, reduced physical activity, increased walk time, low grip strength. Sarcopenia is a muscular disease characterized by low muscle mass and reduced muscle strength as the main determinant. Both conditions can benefit from adequate protein intake (1-1.5 g/kg/day) and regular physical activity. Conclusion: identification, prevention, monitoring and nutritional treatment of frailty and sarcopenia in older adults is important because of its high prevalence. The main goal is to maintain the muscular integrity and minimize muscle loss in older adults. A healthy aging includes regular physical activity and the fulfillment of the protein requirements of this population.
INTRODUCCIÓN: Introducción: la fragilidad y la sarcopenia son dos condiciones altamente prevalentes en el adulto mayor que se solapan en diferentes vertientes del diagnóstico y del tratamiento. Objetivos: analizar la problemática nutricional relacionada con la fragilidad y la sarcopenia en personas de edad avanzada. Métodos: se ha realizado una revisión bibliográfica de las particularidades de la fragilidad y de la sarcopenia, así como del diagnóstico y del tratamiento nutricional. Resultados: la fragilidad es un síndrome geriátrico que puede identificarse si se tienen al menos tres de los siguientes criterios: pérdida de peso, fuerza de presión de la mano disminuida, velocidad de la marcha lenta, actividad física reducida y agotamiento. La sarcopenia es una enfermedad muscular que se caracteriza por una masa muscular baja y una fuerza muscular reducida como determinantes principales. Ambas condiciones pueden verse beneficiadas por un consumo adecuado de proteínas (1-1,5 g/kg/día) y una actividad física de resistencia regular. Conclusión: la identificación, prevención, seguimiento y tratamiento nutricional de la fragilidad y la sarcopenia en adultos mayores es de vital importancia dada su elevada prevalencia. El objetivo es mantener la integridad y minimizar la pérdida muscular en los adultos mayores. Un envejecimiento saludable incluye la realización de actividad física regular y el cumplimiento de los requerimientos proteicos de esta población.
