RESUMO
BACKGROUND: Type 2 diabetes is one of the most prevalent and preventable diseases worldwide and impulsivity, a psychological trait characterized by making quick decisions without forethought, has been suggested as a key feature for health-related conditions. However, there have been no studies examining the relationships between impulsivity and the incidence of type 2 diabetes and our aim was to assess the prospective association between trait impulsivity and the risk of developing type 2 diabetes. METHODS: A prospective observational study design was conducted between May 2014 and February 2023 within the NutriNet-Santé cohort. A web-based platform was used to collect data from the French adult population, with voluntary enrollment and participation. Of the 157,591 adults (≥ 18 years old) participating in the NutriNet-Santé study when impulsivity was assessed, 109,214 participants were excluded due to prevalent type 1 or 2 diabetes or missing data for impulsivity or follow-up data for type 2 diabetes. Trait impulsivity, and the attention, motor, and non-planning subfactors, were assessed at baseline using the Barratt Impulsiveness Scale 11. Incident type 2 diabetes was ascertained through follow-up. Medical information was reviewed by NutriNet-Santé physician experts to ascertain incident diabetes cases based on the ICD-10. Cox regression models, using hazard ratios and 95% confidence intervals (HR [95% CI]), were performed to evaluate associations between impulsivity per 1 standard deviation increment and type 2 diabetes risk, adjusting by recognized confounders. RESULTS: Of the 48,377 individuals studied (women 77.6%; age at baseline = 50.6 year ± 14.5 years), 556 individuals developed type 2 diabetes over a median follow-up of 7.78 (IQR: 3.97-8.49) years. Baseline impulsivity was associated with an increased risk of type 2 diabetes incidence (HR = 1.10 [1.02, 1.20]). The motor impulsivity subfactor was positively associated with type 2 diabetes risk (HR = 1.14 [1.04, 1.24]), whereas no associations were found for attention and non-planning impulsivity subfactors. CONCLUSIONS: Trait impulsivity was associated with an increased type 2 diabetes risk, mainly driven by the motor impulsivity subfactor. If these results are replicated in other populations and settings, trait impulsivity may become an important psychological risk factor to be considered in the prevention of type 2 diabetes.

BACKGROUND: Legume consumption has been linked to a reduced risk of type 2 diabetes (T2D) and cardiovascular disease (CVD), while the potential association between plasma metabolites associated with legume consumption and the risk of cardiometabolic diseases has never been explored. Therefore, we aimed to identify a metabolite signature of legume consumption, and subsequently investigate its potential association with the incidence of T2D and CVD. METHODS: The current cross-sectional and longitudinal analysis was conducted in 1833 PREDIMED study participants (mean age 67 years, 57.6% women) with available baseline metabolomic data. A subset of these participants with 1-year follow-up metabolomics data (n = 1522) was used for internal validation. Plasma metabolites were assessed through liquid chromatography-tandem mass spectrometry. Cross-sectional associations between 382 different known metabolites and legume consumption were performed using elastic net regression. Associations between the identified metabolite profile and incident T2D and CVD were estimated using multivariable Cox regression models. RESULTS: Specific metabolic signatures of legume consumption were identified, these included amino acids, cortisol, and various classes of lipid metabolites including diacylglycerols, triacylglycerols, plasmalogens, sphingomyelins and other metabolites. Among these identified metabolites, 22 were negatively and 18 were positively associated with legume consumption. After adjustment for recognized risk factors and legume consumption, the identified legume metabolite profile was inversely associated with T2D incidence (hazard ratio (HR) per 1 SD: 0.75, 95% CI 0.61-0.94; p = 0.017), but not with CVD incidence risk (1.01, 95% CI 0.86-1.19; p = 0.817) over the follow-up period. CONCLUSIONS: This study identified a set of 40 metabolites associated with legume consumption and with a reduced risk of T2D development in a Mediterranean population at high risk of cardiovascular disease.

To assess the associations between the adherence to a composite score comprised of 6 healthy lifestyle behaviors and its individual components with several cardiometabolic risk factors in Spanish preschool children. Cross-sectional analyses were conducted in 938 participants included in the CORALS cohort aged 3-6 years. Six recognized healthy lifestyle behaviors (breastfeeding, sleep duration, physical activity, screentime, adherence to the Mediterranean diet, and eating speed) were assessed in a composite score. Multiple linear and logistic regression models were fitted to assess the associations with cardiometabolic risk factors (weight status, waist circumference, fat mass index, blood pressure, fasting plasma glucose, and lipid profile). In the adjusted multiple linear and logistic regression models, compared with the reference category of adherence to the healthy lifestyle behavior composite score, those participants in the category of the highest adherence showed significant decreased prevalence risk of overweight or obesity [OR (95% CI), 0.4 (0.2, 0.6)] as well as significant lower waist circumference, fat mass index (FMI), systolic blood pressure and fasting plasma glucose concentration [ß (95% CI), - 1.4 cm (- 2.5, - 0.4); - 0.3 kg/m2 (- 0.5, - 0.1); and - 3.0 mmHg (- 5.2, - 0.9); - 1.9 mg/dL (- 3.5, - 0.4), respectively]. Slow eating speed was individually associated with most of the cardiometabolic risk factors. Conclusions: Higher adherence to the healthy lifestyle behavior composite score was associated with lower waist circumference, FMI, other cardiometabolic risk factors, and risk of overweight or obesity in Spanish preschool children. Further studies are required to confirm these associations. What is Known: ⢠Lifestyle is a well-recognized etiologic factor of obesity and its comorbidities. ⢠Certain healthy behaviors such as adhering to a healthy diet, increasing physical activity, and decreasing screentime are strategies for prevention and treatment of childhood obesity. What is New: ⢠Higher adherence to the healthy lifestyle behavior composite score to 6 healthy behaviors (breastfeeding, sleep duration, physical activity, screentime, eating speed, and adherence to the Mediterranean diet) was associated with decreased adiposity, including prevalence risk of overweight or obesity, and cardiometabolic risk in preschool children. ⢠Slow eating and greater adherence to the Mediterranean diet were mainly associated to lower fasting plasma and serum triglycerides concentration, respectively.

This study aimed to investigate if the duration of breastfeeding and the method at initiation of complementary feeding affect eating behaviour in children aged 3-6 years. This is a cross-sectional analysis from the Childhood Obesity Risk Assessment Longitudinal Study project, an ongoing longitudinal cohort study that aims to identify childhood obesity risk factors in Spanish children. A total of 1215 children aged 3-6 years were included. Breastfeeding duration and the method of initiation of complementary feeding [baby-led weaning (BLW), traditional/spoon or mixed method] were evaluated. Eating behaviour at 3-6 years was assessed with the Child Eating Behaviour Questionnaire. Generalized linear models were fitted to assess the association between the aforementioned exposures and eating behaviour. Children breastfed for ≥4 months were less likely to be fussy eaters at 3-6 years compared to those breastfed for <1 month (OR: 0.86 95% CI: 0.76-0.98; p = 0.031). Compared to those children using the traditional/spoon-feeding method, those initiating complementary feeding through BLW or through a mixed approach were more likely to have higher scores on the enjoyment of food (EF) (OR, 95% CI: 1.33, 1.13-1.57; p = 0.001 and 1.17, 1.05-1.30; p = 0.002, respectively) and lower scores on food fussiness (FF) at 3-6 years (0.76, 0.62-0.91; p = 0.004 and 0.87, 0.78-0.98; p = 0.033, respectively). Breastfeeding for ≥4 months and initiation of complementary feeding with the BLW and a mixed approach were associated with greater EF and lower FF, which should endure practice.
RESUMO
AIMS: Chronic kidney disease (CKD) represents a global health concern, disproportionately affecting the elderly with heightened cardiovascular risk. The emerging focus on the gut microbiota's role in CKD pathophysiology represents a pivotal area in nephrology; however, the evidence on this topic is limited. This observational prospective study, in the framework of the PREDIMED-Plus trial, investigates associations between gut microbiota composition and the 1-year trajectory of CKD in 343 participants aged 55-75 years with high cardiovascular risk. MATERIALS AND METHODS: Kidney function was assessed at baseline and at 1-year of follow-up through the estimated glomerular filtration rate based on cystatin C (eGFR-CysC) and CKD defined by eGFR-CysC <60 mL/min/1.73 m2. Participants were grouped based on their 1-year CKD trajectory: Group 1 maintained normal status or improved from CKD to normal, while Group 2 maintained CKD or worsened from normal to CKD. Fecal microbiota composition was assessed through 16S sequencing. KEY FINDINGS: We observed differences in gut microbiota composition between CKD trajectory groups. Notably, the baseline relative abundance of Lachnoclostridium and Lachnospira, both butyrate-producing genera, was lower in participants maintaining or progressing to CKD. Longitudinally, a decrease in Lachnospira abundance was associated with CKD progression. The improved Chao1 index after 1-year follow-up suggests a link between enhanced microbial richness and stable/better kidney function. SIGNIFICANCE: The findings underscore the potential of gut microbiota analysis in non-invasively monitoring CKD, especially in older populations, and hint at future interventions targeting gut microbiota to manage CKD progression. Further research is needed for causal relationships and generalizability.

STUDY QUESTION: Is ultra-processed food (UPF) consumption associated with semen quality parameters? SUMMARY ANSWER: Higher UPF consumption was inversely associated with total sperm count, sperm concentration, and total motility in men of reproductive age. WHAT IS KNOWN ALREADY: The consumption of UPF, which has been rising during the last decades, has been demonstrated to be positively associated with several chronic diseases such as diabetes or cardiovascular diseases. However, the scientific evidence on its potential impact on semen quality remains notably limited. STUDY DESIGN SIZE DURATION: A cross-sectional analysis was conducted using data from 200 healthy men (mean age 28.4 ± 5.5 years) enrolled in the Led-Fertyl (Lifestyle and Environmental Determinants of Seminogram and Other Male Fertility-Related Parameters) study between February 2021 and April 2023. PARTICIPANTS/MATERIALS SETTING METHODS: UPF consumption (% of energy from UPF) was estimated according to the NOVA classification system using a validated 143-item semi-quantitative food frequency questionnaire. Total sperm count, sperm concentration, sperm vitality, total motility, progressive motility, and normal sperm forms were set as the main outcomes. Microscopic parameters were analyzed using a phase-contrast microscope and a computer-assisted sperm analysis (CASA) system. Semen samples were collected and tested according to World Health Organization 2010 standards. Multivariable linear regression models were fitted to estimate the associations between UPF tertile and semen quality parameters. MAIN RESULTS AND THE ROLE OF CHANCE: Sperm concentration (ß: -1.42 × 106 spz./ml; 95% CI: -2.72 to -0.12) and motility (ß: -7.83%; 95% CI: -15.16 to -0.51) were lower in participants in the highest tertile of UPF compared to the lowest. A similar association was observed for sperm count when UPF was analyzed per 10% increment of energy from UPF consumption (ß: -1.50 × 106 spz.; 95% CI: -2.83 to -0.17). Theoretically replacing 10% of energy from UPF consumption with 10% of energy from unprocessed or minimally processed food consumption was associated with a higher total sperm count, sperm concentration, total motility, progressive motility, and normal sperm forms. LIMITATIONS REASONS FOR CAUTION: Cross-sectional studies do not permit the drawing of causal inferences. Measurement errors and reporting bias cannot be entirely ruled out. WIDER IMPLICATIONS OF THE FINDINGS: This work suggests that consumption of UPF may have an impact on certain semen quality parameters. Furthermore, opting for unprocessed or minimally processed foods instead of UPFs could potentially benefit semen quality. If these results are replicated in future epidemiological studies with different long-term designs, these novel findings could provide valuable insights for updating or even designing preventive and interventional programs to address infertility among men of reproductive age.

RESUMO
Impulsivity has been proposed to have an impact on glycemic dysregulation. However, it remains uncertain whether an unfavorable glycemic status could also contribute to an increase in impulsivity levels. This study aims to analyze associations of baseline and time-varying glycemic status with 3-year time-varying impulsivity in older adults at high risk of cardiovascular disease. A 3-year prospective cohort design was conducted within the PREDIMED-Plus-Cognition substudy. The total population includes 487 participants (mean age = 65.2 years; female = 50.5%) with overweight or obesity and metabolic syndrome. Insulin resistance (HOMA-IR), glycated hemoglobin (HbA1c), presence of type 2 diabetes mellitus, and type 2 diabetes control were evaluated. Impulsivity was measured using the Impulsive Behavior Scale questionnaire and various cognitive measurements. Impulsivity z-scores were generated to obtain Global, Trait, and Behavioral Impulsivity domains. Linear mixed models were used to study the longitudinal associations across baseline, 1-year, and 3-year follow-up visits. HOMA-IR was not significantly related to impulsivity. Participants with higher HbA1c levels, type 2 diabetes, and poor control of diabetes showed positive associations with the Global Impulsivity domain over time, and those with higher HbA1c levels were further related to increases in the Trait and Behavioral Impulsivity domains over the follow-up visits. These results suggest a potential positive feedback loop between impulsivity and glycemic-related dysregulation.
RESUMO
Importance: High intake of ultraprocessed foods (UPFs) has been associated with higher cardiometabolic risk in adults; however, the evidence in children is limited. Objective: To investigate the association between UPF consumption and cardiometabolic risk factors in the Childhood Obesity Risk Assessment Longitudinal Study (CORALS). Design, Setting, and Participants: This baseline cross-sectional analysis was conducted using the data of CORALS participants recruited between March 22, 2019, and June 30, 2022. Preschool children (aged 3-6 years) were recruited from schools and centers in 7 cities in Spain. Inclusion criteria included informed consent signed by parents or caregivers and having a completed a set of questionnaires about the child's prenatal history at home. Exclusion criteria included low command of Spanish or unstable residence. Exposure: Energy-adjusted UPF consumption (in grams per day) from food frequency questionnaires and based on the NOVA food classification system. Main Outcomes and Measures: Age- and sex-specific z scores of adiposity parameters (body mass index [BMI], fat mass index, waist-to-height ratio, and waist circumference) and cardiometabolic parameters (diastolic and systolic blood pressure, fasting plasma glucose, homeostasis model assessment for insulin resistance, high-density and low-density lipoprotein cholesterol, and triglycerides) were estimated using linear regression models. Results: Of 1509 enrolled CORALS participants, 1426 (mean [SD] age, 5.8 [1.1] years; 698 boys [49.0%]) were included in this study. Mothers of children with high UPF consumption were younger, had a higher BMI, were more likely to have overweight or obesity, and had lower education levels and employment rates. Compared with participants in the lowest tertile of energy-adjusted UPF consumption, those in the highest tertile showed higher z scores of BMI (ß coefficient, 0.20; 95% CI, 0.05-0.35), waist circumference (ß coefficient, 0.20; 95% CI, 0.05-0.35), fat mass index (ß coefficient, 0.17; 95% CI, 0.00-0.32), and fasting plasma glucose (ß coefficient, 0.22; 95% CI, 0.06-0.37) and lower z scores for HDL cholesterol (ß coefficient, -0.19; 95% CI, -0.36 to -0.02). One-SD increments in energy-adjusted UPF consumption were associated with higher z scores for BMI (ß coefficient, 0.11; 95% CI, 0.05-0.17), waist circumference (ß coefficient, 0.09; 95% CI, 0.02-0.15), fat mass index (ß coefficient, 0.11; 95% CI, 0.04-1.18), and fasting plasma glucose (ß coefficient, 0.10; 95% CI, 0.03-0.17) and lower HDL cholesterol (ß coefficient, -0.07; 95% CI, -0.15 to -0.00). Substituting 100 g of UPFs with 100 g of unprocessed or minimally processed foods was associated with lower z scores of BMI (ß coefficient, -0.03; 95% CI, -0.06 to -0.01), fat mass index (ß coefficient, -0.03; 95% CI, -0.06 to 0.00), and fasting plasma glucose (ß coefficient, -0.04; 95% CI, -0.07 to -0.01). Conclusions and Relevance: These findings suggest that high UPF consumption in young children is associated with adiposity and other cardiometabolic risk factors, highlighting the need for public health initiatives to promote the replacement of UPFs with unprocessed or minimally processed foods.

BACKGROUND: The health benefits of the Mediterranean diet (MedDiet) have been linked to the presence of beneficial gut microbes and related metabolites. However, its impact on the fecal metabolome remains poorly understood. OBJECTIVES: Our goal was to investigate the weight-loss effects of a 1-y lifestyle intervention based on an energy-reduced MedDiet coupled with physical activity (intervention group), compared with an ad libitum MedDiet (control group), on fecal metabolites, fecal microbiota, and their potential association with cardiovascular disease risk factors. METHODS: A total of 400 participants (200 from each study group), aged 55-75 y, and at high cardiovascular disease risk, were included. Dietary and lifestyle information, anthropometric measurements, blood biochemical parameters, and stool samples were collected at baseline and after 1 y of follow-up. Liquid chromatography-tandem mass spectrometry was used to profile endogenous fecal metabolites, and 16S amplicon sequencing was employed to profile the fecal microbiota. RESULTS: Compared with the control group, the intervention group exhibited greater weight loss and improvement in various cardiovascular disease risk factors. We identified intervention effects on 4 stool metabolites and subnetworks primarily composed of bile acids, ceramides, and sphingosines, fatty acids, carnitines, nucleotides, and metabolites of purine and the Krebs cycle. Some of these were associated with changes in several cardiovascular disease risk factors. In addition, we observed a reduction in the abundance of the genera Eubacterium hallii group and Dorea, and an increase in alpha diversity in the intervention group after 1 y of follow-up. Changes in the intervention-related microbiota profiles were also associated with alterations in different fecal metabolite subnetworks and some cardiovascular disease risk factors. CONCLUSIONS: An intervention based on an energy-reduced MedDiet and physical activity promotion, compared with an ad libitum MedDiet, was associated with improvements in cardiometabolic risk factors, potentially through modulation of the fecal microbiota and metabolome. This trial was registered at https://www.isrctn.com/ as ISRCTN89898870 (https://doi.org/10.1186/ISRCTN89898870).

OBJECTIVES: The evidence on water intake in the prevention of kidney function decline is scarce at population level in well-being individuals at high cardiovascular risk. Therefore, we aimed to longitudinally evaluate the associations between total water intake and subtypes and kidney function, through estimated-Glomerular Filtration Rate (eGFR). METHODS: Three-year prospective analysis conducted in 1986 older adults (aged 55-75 year) with overweight/obesity and metabolic syndrome from the PREDIMED-Plus study. Water intake was assessed using validated beverage and food frequency questionnaires. Serum creatinine-based eGFR (SCr-based eGFR; ml/min/1.73 m2) was estimated using the CKD-EPI equation at baseline, one-year and 3-years of follow-up. Mixed-effects linear regression models were fitted to evaluate the associations between baseline total water intake and subtypes, and SCr-based eGFR over 3-years of follow-up. RESULTS: Participants in the highest baseline tertile of total water intake, plain water and water from all fluids showed a lower decrease in SCr-based eGFR after 3-years of follow-up, compared to those in the lowest tertile. Participants with the highest tap water consumption showed a lower SCr-based eGFR decline after 1-year and 3-years of follow-up, in comparerd to participants in the lowest intake category (T3 vs. T1: ß: 1.4 ml/min/1.73 m2; 95%CI: 0.5-2.3, ß: 1.0; 95%CI: 0.1-2.0, respectively). CONCLUSIONS: Plain water rather than other water sources, and especially tap water, was associated with lower kidney function decline assessed through eGFR over 3-years of follow-up, in older individuals at high cardiovascular risk. TRIAL REGISTRATION: ISRCTN89898870. Retrospectively registered on 24 July 2014.
RESUMO
BACKGROUND: Endocrine disruptors (EDs) have emerged as potential contributors to the development of type-2 diabetes. Perfluorooctane sulfonate (PFOS), is one of these EDs linked with chronic diseases and gathered attention due to its widespread in food. OBJECTIVE: To assess at baseline and after 1-year of follow-up associations between estimated dietary intake (DI) of PFOS, and glucose homeostasis parameters and body-mass-index (BMI) in a senior population of 4600 non-diabetic participants from the PREDIMED-plus study. METHODS: Multivariable linear regression models were conducted to assess associations between baseline PFOS-DI at lower bound (LB) and upper bound (UB) established by the EFSA, glucose homeostasis parameters and BMI. RESULTS: Compared to those in the lowest tertile, participants in the highest tertile of baseline PFOS-DI in LB and UB showed higher levels of HbA1c [ß-coefficient(CI)] [0.01 %(0.002 to 0.026), and [0.06 mg/dL(0.026 to 0.087), both p-trend ≤ 0.001], and fasting plasma glucose in the LB PFOS-DI [1.05 mg/dL(0.050 to 2.046),p-trend = 0.022]. Prospectively, a positive association between LB of PFOS-DI and BMI [0.06 kg/m2(0.014 to 0.106) per 1-SD increment of energy-adjusted PFOS-DI was shown. Participants in the top tertile showed an increase in HOMA-IR [0.06(0.016 to 0.097), p-trend = 0.005] compared to participants in the reference tertile after 1-year of follow-up. DISCUSSION: This is the first study to explore the association between DI of PFOS and glucose homeostasis. In this study, a high baseline DI of PFOS was associated with a higher levels of fasting plasma glucose and HbA1c and with an increase in HOMA-IR and BMI after 1-year of follow-up.

BACKGROUND: The COVID-19 lockdown represented an immense impact on human health, which was characterized by lifestyle and dietary changes, social distancing and isolation at home. Some evidence suggests that these consequences mainly affected women and altered relevant ongoing clinical trials. The aim of this study was to evaluate the status and changes in diet, physical activity (PA), sleep and self-reported health status (SRH) as perceived by older adult men and women with metabolic syndrome during the COVID-19 lockdown. METHODS: We analyzed data from 4681 Spanish adults with metabolic syndrome. We carried out a telephone survey during May and June 2020 to collect information on demographics, dietary habits, PA, sleep, SRH and anthropometric data. RESULTS: The mean age of participants was 64.9 years at recruitment, and 52% of participants were men. Most participants (64.1%) perceived a decrease in their PA during confinement. Regarding gender-specific differences, a higher proportion of women than men perceived a decrease in their PA (67.5% vs. 61.1%), Mediterranean diet adherence (20.9% vs. 16.8%), sleep hours (30.3% vs. 19.1%), sleep quality (31.6% vs. 18.2%) and SRH (25.9% vs. 11.9%) (all p < 0.001). CONCLUSIONS: The COVID-19 lockdown affected women more negatively, particularly their self-reported diet, PA, sleep and health status.

Cognitive decline has been reported as a short-term sequela in patients hospitalized for coronavirus disease-19 (COVID-19). Whether COVID-19 is associated with late cognitive impairment in older free-living individuals with high cardiovascular risk, a group at greater risk of cognitive decline, is unknown. We determined this association of COVID-19 through a longitudinal evaluation of post-COVID-19 cognitive performance and impairment as post hoc analysis in 5,179 older adults (48% female) with mean (SD) age 68.5 (5.0) years, body mass index 31.7 (3.7) kg/m2, harboring ≥ 3 criteria for metabolic syndrome (e.g., hypertension, hyperlipidemia, hyperglycemia etc.) enrolled in PREDIMED-Plus trial. Pre- and post-COVID-19 cognitive performance was ascertained from scheduled assessments conducted using a battery of neuropsychological tests, including 5 domains: Global Cognitive Function, General Cognitive Function, Execution Function, Verbal Fluency and Attention domains, which were standardized for the cohort. Cognitive impairment was defined as the bottom 10 percentile of the sample. Multivariable linear and logistic regression models assessed the association of COVID-19 with cognitive decline and impairment, respectively. After a mean 50-week follow-up, no significant associations were observed between COVID-19 status and post-COVID-19 scores of all tapped neuropsychological domains, except Global Cognitive Function (GCF). When fully adjusted, COVID-19 was marginally associated with higher (better) post-pandemic GCF score (ßadj (95% CI): 0.06 (0.00, 0.13) p=.05). However, the odds for post-COVID-19 cognitive impairment in GCF domain were not associated with the disease (ORadj (95% CI): 0.90 (0.53, 1.51) p=.68). In the PREDIMED-Plus cohort, COVID-19 status and cognitive impairment determined 50 weeks post-infection showed no association in older adults at high cardiovascular risk. This suggests that cognitive changes observed shortly after COVID-19 revert over time. However, cautious interpretation is warranted as these data were obtained within the framework of a clinical trial encouraging a healthy lifestyle.
RESUMO
El objetivo de este artículo es resumir de manera objetiva el informe del Comité Científico Europeo que acaba de actualizar el algoritmo en el que se basa el logotipo nutricional Nutri-Score. Se revisa la metodología utilizada, las prioridades establecidas y sus justificaciones, y los diferentes escenarios probados, las modificaciones propuestas y su impacto en los diferentes grupos de alimentos afectados.El Comité Científico consideró que el algoritmo actual funciona en general bien, pero ha introducido algunas mejoras. Las modificaciones recomendadas por el Comité permiten corregir algunas limitaciones identificadas: clasificación de los aceites, pescados grasos, productos integrales, frutos secos y quesos, así como la penalización superior de los alimentos muy azucarados o muy salados, productos lácteos azucarados, platos preparados y carnes rojas, entre otros, manteniendo al mismo tiempo la coherencia global del sistema y la clasificación general de los productos entre ellos. Con la actualización del algoritmo de Nutri-Score se observa globalmente una mejor alineación entre las clasificaciones obtenidas por Nutri-Score y las recomendaciones dietéticas en vigor en los diferentes países europeos que lo han adoptado.

The aim of this article is to objectively summarize the report of the European Scientific Committee in charge of updating the algorithm underlying the front-of-pack Nutritional label Nutri-Score. It described the methodology used and the priorities established, the scientific rational and the different scenarios tested, the proposed modifications and their impact on the different food groups concerned.The Scientific Committee considered that its current algorithm works globally well, but has introduced some improvements. Modifications recommended allow to correct some of its identified limits: classification of oils, fatty fish, whole grain products, nuts, cheeses, higher penalization of very sugary or very salty foods, sweet dairy products, composite products, red meat... while maintaining the overall consistency of the system and the classification of the products. The update of the Nutri-Score algorithm permits a better alignment between the Nutri-Score classifications and Nutritional recommendations disseminated in the different European countries that have adopted it.

Chronic diseases and aging are placing an ever increasing burden on healthcare services worldwide. Nutritional counselling is a priority for primary care because it has shown substantial cost savings. This review aims to evaluate the evidence of the cost-effectiveness of nutritional care in primary care provided by health professionals. A literature search was conducted using PubMed/MEDLINE between January 2000 and February 2019. The review included thirty-six randomized controlled trials (RCTs) and systematic reviews conducted in healthy people and people with obesity, type-2 diabetes mellitus, cardiovascular risk or malnutrition. All the RCTs and reviews showed that nutritional intervention led by dietitians-nutritionists in people with obesity or cardiovascular risk factors was cost-effective. Dietary interventions led by nurses were cost-effective in people who needed to lose weight but not in people at high cardiovascular risk. Some dietary changes led by a primary care team in people with diabetes were cost-effective. Incorporating dietitians-nutritionists into primary care settings, or increasing their presence, would give people access to the healthcare professionals who are best qualified to carry out nutritional treatment, and may be the most cost-effective intervention in terms of health expenditure. Notwithstanding the limitations described, this review suggests that incorporating dietitians-nutritionists into primary health care as part of the multidisciplinary team could be regarded as an investment in health. Even so, more research is required to confirm the conclusions
Las enfermedades crónicas y el envejecimiento suponen una carga cada vez mayor para los servicios de salud en todo el mundo. El asesoramiento nutricional es una prioridad para la atención primaria porque ha demostrado ahorros sustanciales de costes. Esta revisión tiene como objetivo evaluar la evidencia de la relación coste-efectividad de la atención nutricional en la atención primaria proporcionada por profesionales de la salud. Se realizó una búsqueda bibliográfica utilizando PubMed/MEDLINE entre enero de 2000 y febrero de 2019. La revisión incluyó 36 ensayos controlados aleatorios (ECA) y revisiones sistemáticas realizadas en personas sanas y personas con obesidad, diabetes mellitus de tipo 2, riesgo cardiovascular o desnutrición. Todos los ECA y las revisiones mostraron que la intervención nutricional dirigida por dietistas-nutricionistas en personas con obesidad o factores de riesgo cardiovascular fue coste-efectiva. Las intervenciones dietéticas dirigidas por enfermeras fueron coste-efectivas en personas que necesitaban perder peso pero no en personas con alto riesgo cardiovascular. Algunos de los cambios en la dieta dirigidos por un equipo de atención primaria en personas con diabetes también fueron coste-efectivos. La incorporación de dietistas-nutricionistas en entornos de atención primaria, o aumentar su presencia, daría a las personas acceso a los profesionales de la salud mejor calificados para llevar a cabo el tratamiento nutricional, y resultaría más rentable en términos de gasto en salud. A pesar de las limitaciones descritas, esta revisión sugiere que incorporar dietistas-nutricionistas en atención primaria como parte del equipo multidisciplinario podría considerarse una inversión en salud. Aun así, se requiere más investigación para confirmar las conclusiones

BACKGROUND: to date, gluten-free (GF) diet is the only treatment available for individuals with celiac disease. Both individual and collective food intake assessments are a challenge because a food composition database of GF products (GFPs) is lacking. OBJECTIVES: to describe the process of developing a food composition database of GFPs, and to compare the nutritional profile and price of some GFPs and non-GFPs. METHODS: initially, a total of 216 brands of GFPs marketed in Spain were recorded. Nutritional information was collected from nutritional labels and product fact sheets that had been provided by food companies or collected first-hand by researchers. Then, the nutritional profile and price of the cereal and cereal byproducts foodstuff groups, including 19 types of products, were compared. Statistical analyses were performed using the SPSS statistical program (22.0 edition; SPSS, Chicago, IL, USA). RESULTS: a total of 2,247 GFPs from 126 different foodstuff brands were included in the food composition database of GFPs (CELIAC-BASE). We classified these products into 14 foodstuff groups. The protein content of the GFPs studied was significantly lower, and the price was higher, than that of their non-GFP counterparts. Some, but not all, GFPs had a higher content of fat and sugar, and a lower content of dietary fiber as compared to their non-GFP counterparts. Some GFPs were up to 6 times more expensive than the corresponding non-GFPs. CONCLUSIONS: CELIAC-BASE is a pioneering tool for dietitians. Many GFPs have poor nutritional profiles and should be consumed only occasionally in a balanced GF diet
INTRODUCCIÓN: hasta la fecha, una dieta sin gluten (SG) es el único tratamiento para las personas con enfermedad celíaca. Tanto las evaluaciones de ingesta de alimentos individuales como las colectivas son un desafío debido a la falta de una base de datos de composición de productos SG (PSG). OBJETIVOS: describir el proceso de desarrollo de una base de datos de composición de PSG y comparar el perfil nutricional y el precio de algunos PSG y productos con gluten. MÉTODOS: inicialmente, se registraron un total de 216 marcas de PSG comercializadas en España. La información nutricional se recopiló de las etiquetas nutricionales y hojas informativas de los productos, que habían sido proporcionadas por las compañías de alimentos o recopiladas de primera mano por los investigadores. Luego, se compararon el perfil nutricional y el precio de los grupos de cereales y subproductos alimenticios, incluidos 19 tipos de productos. Los análisis estadísticos se realizaron utilizando el programa estadístico SPSS (edición 22.0; SPSS, Chicago, IL, EUA). RESULTADOS: se incluyeron un total de 2247 PSG de 126 marcas de alimentos diferentes en la base de datos de composición de PSG (CELIAC-BASE). Clasificamos estos productos en 14 grupos de alimentos. El contenido de proteínas de los PSG estudiados fue significativamente menor, y el precio de los mismos fue más alto, que el de sus homólogos con gluten. Algunos PSG, pero no todos, presentaron un mayor contenido de grasa y azúcar, y un menor contenido de fibra dietética, que sus homólogos con gluten. Algunos PSG eran hasta 6 veces más caros que sus homólogos con gluten. CONCLUSIONES: CELIAC-BASE es una herramienta pionera para dietistas-nutricionistas. Muchos PSG tienen perfiles nutricionales no saludables y deben consumirse solo ocasionalmente en una dieta equilibrada libre de gluten

INTRODUCCIÓN Y OBJETIVOS: La estrategia Life's Simple 7 de la American Heart Association propuso 7 métricas de salud cardiovascular ideal: índice de masa corporal (IMC)<25, no fumar, dieta saludable, actividad física moderada ≥ 150min a la semana, colesterol total <200mg/dl, presión arterial sistólica <120mmHg y diastólica <80mmHg y glucemia basal <100mg/dl. Resulta de gran interés valorar el efecto combinado de estas 7 metas. Se analizó prospectivamente el impacto de las métricas basales Life's Simple 7 en la incidencia de eventos cardiovasculares mayores en la cohorte PREDIMED (el 57,5% mujeres; media de edad inicial, 67 años). MÉTODOS: La métrica de dieta saludable se definió como alcanzar al menos 9 puntos en una escala validada de 14 puntos de adhesión a dieta mediterránea. Se definió evento cardiovascular mayor incidente como infarto de miocardio, ictus o muerte de causa cardiovascular. Se usó regresión de Cox para estimar hazard ratios (HR) ajustadas multivariables con intervalos de confianza del 95% (IC95%) para categorías sucesivas de métricas de salud cardiovascular. RESULTADOS: Tras seguir a 7.447 participantes durante una mediana de 4,8 años, se registraron 288 eventos. Respecto a los participantes con solo 0-1 métricas, tras ajustar por edad, sexo, centro y grupo de intervención, se observaron HR (IC95%) 0,73 (0,54-0,99), 0,57 (0,41-0,78) y 0,34 (0,21-0,53), para 2, 3 y 4 o más métricas respectivamente. CONCLUSIONES: En una población española con alto riesgo cardiovascular, la presencia de un mayor número de métricas se asoció progresivamente con una reducción sustancial en la tasa de eventos cardiovasculares mayores
INTRODUCTION AND OBJECTIVES: The Life's Simple 7 strategy of the American Heart Association proposes 7 metrics of ideal cardiovascular health: body mass index (BMI) <25mg/m2, not smoking, healthy diet, moderate physical activity ≥ 150min/wk, total blood cholesterol <200mg/dL, systolic and diastolic blood pressures <120 and <80mmHg, respectively, and fasting blood glucose <100mg/dL. It is important to assess the combined effect of these 7 metrics in the Spanish population. We prospectively analyzed the impact of baseline Life's Simple 7 metrics on the incidence of major cardiovascular events in the PREDIMED cohort (57.5% women, average baseline age, 67 years). METHODS: The healthy diet metric was defined as attaining ≥ 9 points on a validated 14-item Mediterranean diet adherence screener. An incident major cardiovascular event was defined as a composite of myocardial infarction, stroke, or cardiovascular death. Cox regression was used to calculate multivariable adjusted hazard ratios (HR) and their 95% confidence intervals (95%CI) for successive categories of health metrics. RESULTS: After a median follow-up of 4.8 years in 7447 participants, there were 288 major cardiovascular events. After adjustment for age, sex, center, and intervention group, HRs (95%CI) were 0.73 (0.54-0.99), 0.57 (0.41-0.78), and 0.34 (0.21-0.53) for participants with 2, 3, and ≥ 4 metrics, respectively, compared with participants with only 0 to 1 metrics. CONCLUSIONS: In an elderly Spanish population at high cardiovascular risk, better adherence to Life's Simple 7 metrics was progressively associated with a substantially lower rate of major cardiovascular events

El Ministerio de Sanidad de España, en noviembre de 2018, notificó oficialmente la adopción del etiquetado nutricional frontal Nutri-Score que permitirá a los consumidores juzgar fácilmente la calidad nutricional de los alimentos en el momento de la compra e incitar a los industriales a mejorar la composición nutricional de sus productos alimentarios. Este artículo sintetiza los trabajos científicos realizados que ponen en relieve la validación del perfil nutricional que subyace al cálculo de Nutri-Score, y los trabajos que demuestran su eficacia y superioridad con respecto a otros logotipos existentes o propuestos por agentes económicos. Asimismo, se hace un balance de su desarrollo en España y en el seno de la Unión Europea y se responde a las fake-news transmitidas por sus detractores. Se presenta también la Iniciativa Ciudadana Europea para que este etiquetado frontal sea obligatorio en Europa
The Spanish Ministry of Health, in November 2018, notified the officially adoption of the front-of-pack nutrition label Nutri-Score which will allow consumers to easily judge the nutritional quality of food at the time of purchase and to encourage industrialists to improve the nutritional composition of food. This article synthesizes the scientific work pertaining to the validation of the nutritional profile that underlies the computation of Nutri-Score and works that demonstrate its effectiveness and superiority in comparison to other existing logos or proposed by food companies. Likewise, it highlights its development in Spain and within the European Union and responds to the fake-news raised by its detractors. It also introduces the European Citizens' Initiative to make it compulsory in Europe

Introduction: metabolic syndrome (MS) components are independent risk factors for the development of cardiovascular disease and type 2 diabetes, major causes of mortality in the world. Objective: to evaluate the frequency of MS components and its association with sociodemographic variables and physical activity among young health professionals at the University of Guadalajara. Methods: a cross-sectional study entitled LATIN America METabolic Syndrome Mexico (LATINMETS-Mex) was conducted. Weight, height, waist circumference, blood pressure, triglycerides, glucose and HDL cholesterol were measured. Socio-demographic and physical activity data were surveyed. MS components were diagnosed based on the revised criteria of Alberti et al. (2009). Associations were assessed using logistic regression adjusted for age and sex. Results: a total of 316 volunteer subjects were analyzed (70.9% women, 83.8% ≤ 29 years). The frequency of MS was 7.0% and 55.5% of subjects presented one or more MS components (27.2% abdominal obesity, 26.6% low HDL cholesterol). After adjustment, abdominal obesity, high blood pressure and hypertriglyceridemia were positively associated with BMI ≥ 25 kg/m2. High blood pressure and hypertriglyceridemia were negatively associated with being female while low HDL cholesterol was positively associated with this gender after adjustment. Abdominal obesity was the only component negatively associated with physical activity (300 to 600 minutes per week) after adjusting for age and sex. No association between MS and sociodemographic variables or physical activity was found. Conclusions: half of the participants presented one or more metabolic syndrome components. Actions are required to reduce cardiometabolic risk in the study population considering the sociodemographic and lifestyle variables associated
Introducción: los componentes del síndrome metabólico (SM) son factores de riesgo independientes para desarrollar enfermedades cardiovasculares y metabólicas, principales causas de mortalidad en el mundo. Objetivo: evaluar la frecuencia de componentes del SM y su asociación con variables sociodemográficas y actividad física en profesionales de la salud jóvenes de la Universidad de Guadalajara. Métodos: diseño transversal derivado del estudio multicéntrico LATIN America METabolic Syndrome (LATINMETS). Se midieron peso, talla, cintura, presión arterial y concentración sanguínea de triglicéridos, glucosa y colesterol HDL. Se preguntaron datos sociodemográficos y actividad física. Los componentes del SM se diagnosticaron con los criterios de Alberti y cols. (2009). Las asociaciones se evaluaron con regresión logística ajustada por edad y sexo. Resultados: se analizaron 316 voluntarios (70,9% mujeres, 83,8% ≤ 29 años). La frecuencia de SM fue del 7,0% y el 55,5% presentó uno o más componentes (27,2% obesidad abdominal, 26,6% hipocolesterolemia HDL). Después del ajuste, la obesidad abdominal, la presión arterial elevada y la hipertrigliceridemia se asociaron positivamente con un IMC ≥ 25 kg/m2. Ser mujer se asoció negativamente con presión arterial elevada e hipertrigliceridemia y se asoció positivamente con hipocolesterolemia HDL después del ajuste. La obesidad abdominal se asoció negativamente con actividad física (300 a 600 minutos por semana) después de ajustar por edad y sexo. El SM no se asoció con variables sociodemográficas ni de actividad física. Conclusiones: la mitad de los participantes presentaron uno o más componentes del SM. Se requieren acciones para reducir el riesgo cardiometabólico en la población estudiada considerando las variables sociodemográficas y de estilo de vida asociadas

Las guías nutricionales incorporan los lácteos como parte de una dieta equilibrada y saludable. En la mayoría de las ocasiones se especifica que los productos lácteos sean preferentemente bajos en grasa o desnatados. La razón que subyace a esta limitación es el aporte de ácidos grasos saturados (AGS) inherente al consumo de grasa láctea. Recientemente se ha planteado que valorar los alimentos según el aporte de nutrientes que contienen de forma aislada conlleva a interpretar de forma limitante sus funciones y propiedades. El conocimiento de la matriz alimentaria permite valorar el efecto sobre la salud de los alimentos en su totalidad al considerar, todos los componentes que contiene, y la interacción tras su consumo. Los productos lácteos son un ejemplo para destacar la importancia de la matriz alimentaria como un determinante del efecto que pueden ejercer los nutrientes del alimento. Los efectos potencialmente nocivos de los AGS sobre la salud cardiometabólica parecen no ser tales cuando se consumen como parte de alimentos con matrices alimentarias ricas en nutrientes como son la leche, el yogur, el queso u otros productos lácteos. Estudios epidemiológicos de grandes cohortes poblacionales seguidas a largo plazo muestran que el consumo de productos lácteos, especialmente de yogur, no se asocia con un aumento del riesgo cardiovascular. Por tanto, no existen suficientes evidencias científicas para recomendar a la población general el consumo de productos lácteos bajos en grasa o desnatados de forma preferente, en lugar de su versión entera
The nutritional guidelines incorporate dairy products as part of a balanced and healthy diet. In almost all guidelines it is announced that dairy products have to preferably be consumed as non or low-fat version. The reason behind this recommendation is the intake of saturated fatty acids (SFA). Recently, it has been suggested that building nutritional recommendations according to the nutrient food content, leads to a limiting interpretation of the functions and properties of the consumed food. Lately, the research focus has been shifted towards the study of the food matrix, which allows assessing health effects considering all the components contained in the foods, and their impact in human health. Dairy products are the perfect example to highlight the importance of the food matrix as a determinant of the effects of nutrients on health. The potentially harmful effects of SFA on cardiometabolic health seem to be different when they are consumed within nutrient-rich foods such as yogurt, cheese or other dairy products. Epidemiological studies with large population cohorts and long term follow-up show that consumption of dairy products, especially yogurt, is not associated with an increased cardiovascular risk. Therefore, there is not enough scientific evidence to preferentially recommend the consumption of non-fat or low-fat dairy products to the general population, instead of its whole-fat version
