Existing differences between available lists of FODMAP-containing foods.

BACKGROUND AND AIM: reduced intake of fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs) is useful to treat functional gastrointestinal disorders. However, there is no consensus on which foods should be included in the FODMAP list as FODMAP profile characterization is lacking for many different foods. This study aimed to emphasize the need for a unified FODMAP list to prevent patient confusion. We hypothesized that FODMAP lists do not include all products that may contain high levels of FODMAPs. METHODS: PubMed, ScienceDirect, Scielo, and Cochrane were searched to identify food composition tables, reviews, food analysis publications, laboratory analyses, and clinical trials containing FODMAP lists. RESULTS: of 1,308 articles identified, 10 were selected; 22.6 % of the 204 foods listed were classified differently among studies. This included almonds, avocados, banana, broccoli, soft cheese, eggplant, and walnuts. Nutritional guidance may be taken from existing FODMAP-related literature, but the information given is not always consistent. CONCLUSION: Unvarying lists of low FODMAP foods should be compiled to provide patients with accurate information on FODMAP dieting.

Lifestyle factors, diet and attention-deficit/hyperactivity disorder in Spanish children - an observational study.

Background: The aetiology of Attention Deficit Hyperactivity Disorder (ADHD) continues to be debated, although several contributing factors have been acknowledged.Objective: Assess the association between weight, birth attributes, exercise and sleep habits, dietary intake and adherence to a Mediterranean diet, and impulsive behaviour on Spanish ADHD children. Establish whether specific food groups (not just adherence to the Mediterranean diet) associate with impulsive behaviour.Methods: This observational cross-sectional study included 57 ADHD children from Madrid (Spain). Demographic, clinical data, sleep, exercise and technology-use habits were obtained. Anthropometric measurements included height and weight. Adherence to the Mediterranean diet was assessed using the KIDMED test. Barratt Impulsivity Scale version-11c was used to assess impulsivity. Subjects were divided into three groups for analysis, according to their age (6-10 years, children; 11-13 years, pre-adolescents; 14-16 years, adolescents).Results: There were clear associations between those who had higher BIS scores and who slept less at weekends (49.4 ± 10.16 vs. 43.8 ± 12.51), who adhered poorly to the Mediterranean diet (49.9 ± 11.72 vs. 41.6 ± 16.52), who used internet and technological devices for >3 h/day (45.5 ± 13.6 vs. 44.7 ± 12.11), who were born with >2.5 kg (46.1 ± 11.61 vs. 42.9 ± 15.29), who were delivered by caesarean (45.1 ± 12.78 vs. 44.7 ± 12.5) and who were not breastfed (45.0 ± 13.38 vs. 44.8 ± 12.39). Subjects exercising more than 3 days a week also scored slightly higher (45.4±14.02 vs. 44.6±11.85) in the BIS.Conclusion: There is a need to follow up the link between ADHD and sleep onset difficulties, dietary patterns, technological habits, perinatal factors, breastfeeding and birth delivery mode.

Nutritional and environmental factors in attention-deficit hyperactivity disorder (ADHD): A cross-sectional study.

OBJECTIVES: Attention-deficit hyperactivity disorder (ADHD) has been related to nutrient deficiencies and 'unhealthy' diets, and to date there is only one study that examined the relationship between the Mediterranean diet and ADHD. The aim was to determine the association between those environmental, nutritional, and body composition factors that may affect the pathogenesis and symptomatology of patients with ADHD in Spain. METHODS: A total of 89 children and adolescents (41 with diagnosed ADHD and 48 controls) were studied in an observation case-control study. Anthropometry, nutritional status, adherence to a Mediterranean diet, sedentary behaviour, and sleep were measured. RESULTS: Lower adherence to a Mediterranean diet was associated with ADHD diagnosis. Individuals with ADHD more often missed having a second serving of vegetables daily and showed reduced intakes of fish, pulses, and pasta or rice almost every day when compared with controls. Statistically significant differences (P < 0.05) were found for fish, cereal, no breakfast and commercially baked goods consumption. There were also statistically significant differences between ADHD individuals and controls when analysing sedentary behaviours and BMI (P < 0.05). CONCLUSION: Low adherence to a Mediterranean diet might play a role in ADHD development. Not only specific nutrients but also the whole diet should be considered in ADHD. No clear association was found for anthropometry and sedentary behaviours.

Effects of Gluten on Gut Microbiota in Patients with Gastrointestinal Disorders, Migraine, and Dermatitis.

As gluten may trigger gastrointestinal disorders (GIDs), its presence or absence in the diet can change the diversity and proportion of gut microbiota. The effects of gluten after six weeks of a double-blind, placebo-controlled intervention with a gluten-free diet (GFD) were studied in participants with GIDs suffering from migraines and atopic dermatitis (n = 46). Clinical biomarkers, digestive symptoms, stool, the Migraine Disability Assessment questionnaire, and zonulin levels were analyzed. Next-generation sequencing was used to amplify the 16S rRNA gene of bacteria and the internal transcribed spacer (ITS) regions of fungi. The GFD increased Chao1 fungal diversity after the intervention, while the fungal composition showed no changes. Bacterial diversity and composition remained stable, but a positive association between bacterial and fungal Chao1 diversity and a negative association between Dothideomycetes and Akkermansia were observed. GIDs decreased in both groups and migraines improved in the placebo group. Our findings may aid the development of GID treatment strategies.

Effect of MetioNac® in patients with metabolic syndrome who are at risk of metabolic dysfunction associated fatty liver disease: a randomized controlled trial.

Introduction: Introduction: metabolic syndrome comprises a combination of diabetes, high blood pressure, and obesity, and metabolic associated fatty liver disease (MAFLD) is associated with it. Objective: to evaluate the effect of supplementation with S-adenosyl-L-methionine + N-acetylcysteine + thioctic acid + vitamin B6 (MetioNac®) for 3 months on lipidic and biochemical parameters in subjects with metabolic syndrome and at risk of MAFLD. The reduction in body weight and the oxidative stress markers malondialdehyde (MDA) and superoxide dismutase (SOD) were also evaluated. Methods: patients with metabolic syndrome, at risk of MAFLD (FIB-4 < 1.30), and with an indication for weight reduction were recruited (n = 15). Control group followed a semipersonalized Mediterranean diet (MD) for weight reduction, according to the recommendations of the Spanish Society for the Study of Obesity (SEEDO). Experimental group, in addition to the MD, took three capsules of MetioNac® supplement per day. Results: compared with the control group, subjects taking MetioNac® showed significant (p < 0.05) reductions in the levels of TG and VLDL-c, as well as in total cholesterol, LDL-c, and glucose levels. They also showed increased levels of HDL-c. Levels of AST and ALT decreased after the intervention with MetioNac®, but this decrease did not reach statistical significance. Weight loss was observed in both groups. Conclusion: supplementation with MetioNac® may be protective against hyperlipidemia, insulin resistance, and overweight among metabolic syndrome patients. Further studies on this issue are needed in a larger population.

Introducción: Introducción: el síndrome metabólico se define como una combinación de diabetes, hipertensión arterial y obesidad, que se asocia con la enfermedad del hígado graso asociada a disfunción metabólica. Objetivo: evaluar el efecto de la suplementación con S-adenosil-L-metionina + N-acetilcisteína + ácido tióctico + vitamina B6 (MetioNac®) durante 3 meses sobre parámetros lipídicos y bioquímicos en sujetos con síndrome metabólico y en riesgo de enfermedad del hígado graso asociada a disfunción metabólica. También se evaluaron la reducción del peso corporal y los marcadores de estrés oxidativo malondialdehído (MDA) y superóxido dismutasa (SOD). Métodos: se reclutaron pacientes con síndrome metabólico, riesgo de enfermedad del hígado graso asociada a disfunción metabólica (FIB-4 < 1,30) y con indicación de reducción de peso (n = 15). El grupo control siguió una dieta mediterránea (DM) semipersonalizada para la reducción de peso, de acuerdo con las recomendaciones de la Sociedad Española para el Estudio de la Obesidad (SEEDO). El grupo intervención, además de la DM, tomó tres cápsulas diarias de MetioNac®. Resultados: en comparación con el grupo de control, los sujetos que tomaron MetioNac® mostraron reducciones significativas (p < 0.05) en los niveles de TG y VLDL-c, así como en los niveles de colesterol total, LDL-c y glucosa. También mostraron niveles elevados de HDL-c. Los niveles de AST y ALT disminuyeron después de la intervención con MetioNac®, pero esta disminución no fue estadísticamente significativa. También se observó una pérdida de peso en ambos grupos. Conclusión: la suplementación con MetioNac® puede proteger contra la hiperlipidemia, la insulinorresistencia y el sobrepeso en pacientes con síndrome metabólico. Sin embargo, es necesario realizar más estudios y seleccionar un mayor número de participantes.

Knowledge and attitudes towards baby-led-weaning by health professionals and parents: A cross-sectional study.

OBJECTIVE: Baby-led-weaning (BLW) is a novel model of complementary feeding. Although there is little scientific evidence to support the suitability or superiority of this complementary feeding model, BLW is followed by many families today. The aim was to evaluate the knowledge and attitudes of a group of parents and health professionals regarding BLW in Spain. METHODS: This research was designed as a cross-sectional study in a sample of 502 parents and 364 health professionals. Two questionnaires generated and disseminated through Google forms were used. The differences between groups of professionals were analyzed using the Chi-Square test. RESULTS: 92.3% of professionals and 93.4% of parents knew about BLW. They recommend BLW "always" in 39.8% and 69.3% of the cases, and "sometimes" in 49.7% and 24.9%, respectively. Of the health professionals, 80.5% recommended starting complementary feeding as of six months, 36% of them using BLW, 24% followed traditional weaning, 3.3% bottle feeding and the remaining 36% did not indicate. Eighty-three percent recommended chewing as soon as the child showed interest. CONCLUSION: Both health professionals and parents recommend BLW and consider it helps promote the developmental milestones of the baby. Providing nurses with an adequate number of resources to guide parents on complementary feeding will continue to improve childcare.

Bioavailability of magnesium food supplements: A systematic review.

OBJECTIVES: The market for food supplements is booming thanks to their increased consumption. European regulations include different ways in which vitamins and minerals are administered, without making it clear to the consumer whether one formulation has advantages over the other. The aim of this review was to compare the bioavailability of different forms of magnesium and analyze the differences between them. METHODS: Based on a PICO (population, intervention, comparison, outcome) research question, a search strategy was established for magnesium bioavailability studies comparing different forms in the PubMed, Cochrane, Web of Science, and Scopus databases. We found 433 studies, out of which 14 were finally selected. RESULTS: Inorganic formulations appear to be less bioavailable than organic ones, and the percentage of absorption is dose dependent. CONCLUSIONS: All magnesium dietary supplements can maintain physiological levels in healthy people without prior deficit, although this cannot be assured in older people or those with illnesses or previous subphysiological levels.

Effectiveness of an intermittent fasting diet versus continuous energy restriction on anthropometric measurements, body composition and lipid profile in overweight and obese adults: a meta-analysis.

The effects of an intermittent fasting (IF) diet in the overweight or obese adult population are still controversial. This study aimed to evaluate the effectiveness of an IF diet to reduce anthropometric parameters (body mass index, body weight, and waist circumference), change body composition (fat mass, lean body mass and muscle mass) and lipid profile (total cholesterol, HDL-c, LDL-c and triglycerides), and to adhere to the diet in comparison to continuous energy restriction (CER) in overweight or obese adults. A research question PICO (patients, intervention, comparison, outcome) was established. PubMed, Scopus, Web of Science, Cochrane, and Scielo databases were searched to identify randomized clinical trials that compared an IF diet with a CER diet or a regular diet. DeCS and MeSH descriptors and Boolean operators (AND and OR) were used. From 859 studies identified through the literature search, 18 articles were finally selected. Overall, IF diets were associated with higher weight loss in four studies and similar reduction in waist circumference in one study, compared with a CER regimen. Fat mass tended to decrease more in the IF groups in five studies. However, the lean and muscle mass loss was similar in both groups. Only three studies observed significant differences in lipid profile variables, mostly in the IF groups. Adherence to the diet was inconclusive. An IF diet may provide a benefit by improving anthropometry, body composition, and lipid profile in overweight or obese adult population, likewise a CER diet.

Successful Implementation of a Mediterranean Weight Loss Program to Prevent Overweight and Obesity in the Workplace.

OBJECTIVE: Reducing obesity is a priority for employers seeking to lower the incidence and severity of chronic illness and associated health services. The aim was to identify if a workplace-based dietary intervention monitored by health professionals is effective at reducing obesity, as part of an obesity-control-program at work. METHODS: A 12-week dietary intervention was designed for 102 overweight/obese Spanish employees in Madrid. Dietary and anthropometric (height, weight, body mass index [BMI], fat mass, and waist circumference) assessment was conducted at baseline, follow-up, and final. Six 20-minute counseling sessions were undertaken by participants. RESULTS: Significant post-intervention reductions were observed in all anthropometric measures. 77.5% of the participants were considered respondents to the intervention, while 22.5% remaining were not. A higher proportion of women responded positively to the treatment compared with men. However, higher decrease in anthropometric measures were observed in men. CONCLUSION: The workplace is deemed to be effective for providing guided dietary intervention and behavioral support based on the proximity of health professionals to the employee.

Modulation of plasma triglycerides concentration by sterol-based treatment in children carrying different genes.

BACKGROUND: Dyslipidemias have increased during the last decades in children. AIM: The objective of this study was to analyze the influence of different polymorphisms in plasma triglyceride levels of children following a dietary treatment with plant sterols. DESIGN: A randomized, double-blind, crossover, controlled clinical trial was carried out in 26 children (16 women). MATERIALS AND METHODS: Commercial milk, with 2.24 g sterols, was ingested daily during 3 weeks , and the same amount of kimmed milk without sterols, during the 3 week placebo phase. Both phases were separated by a washout period of 2 weeks. At the beginning and end of each phase, blood draws were performed. RESULTS: Apolipoprotein A5 Ser19Trp (P = 0.002), peroxisome proliferator-activated receptor-alpha L162V (P = 0.003), APOE APOE2/3/4 (P = 0.012), and APOE APOE2,3,4 (P = 0.025) show statistically significant differences between their haplotypes in plasma triglyceride levels. Other genes did not show statistically significant differences. CONCLUSIONS: Further studies are needed to establish which genotype combinations would be the most protective against hypertriglyceridemia.

Hydration Status: Influence of Exercise and Diet Quality.

Physical activity, adherence to a healthy diet, and healthy beverage pattern are considered essential components of a healthy lifestyle. We aimed to evaluate the associations between physical exercise, diet quality, and total fluid intake, along with fluid recommendations compliance in a sample of adults. Data on fluid intake from different types of beverages were collected in a cross-sectional study, in 1161 men and women between 18 and 65 years of age, using a fluid-specific diary. Exercise was evaluated with a self-reported questionnaire, and quality of diet was assessed using the Healthy Eating Index-2010 (HEI). Mean volume of water consumed was 1497.5 mL for men, 1309.5 mL for women. A total of 37.4% did not follow the recommendations of the European Food Safety Agency for total water intake. There was a statistically significant difference (P = .002) between total water intake and follow-up of recommendations, as well as for sex (P < .001). Mean HEI-2010 score was 65.21. There were no statistically significant differences (P = .301) in HEI index among better or worse hydration. Sport variables had influence on milliliters of water consumed (P < .001). Participants who engaged in more physical exercise exhibit a healthier pattern of fluid intake. Healthy individuals with the highest scores for HEI-2010 did not present the healthiest beverage patterns.

Gene Influence in the Effectiveness of Plant Sterols Treatment in Children: Pilot Interventional Study.

Cardiovascular disease is linked to high serum low density lipoprotein (LDL)-cholesterol levels. Cardiovascular risk may be indirectly influenced by genetic load. Serum LDL-cholesterol levels may be reduced by the consumption of food enriched with plant sterols (PS). The aim was to test a plant sterol treatment on cholesterol levels according to different genetic polymorphisms. A pilot interventional trial was performed in 26 children (n = 16 girls, n = 10 boys). Seven hundred milliliters/day of commercial skimmed milk with added plant sterols delivering 2.2 g plant sterols were ingested for three weeks. Blood draws were performed at the baseline and end of the study. Significant modifications of non-high density lipoprotein (HDL)-cholesterol (p = 0.010; p = 0.013) and LDL-cholesterol (p = 0.004; p = 0.013) levels appeared in the genes LIPC C-514T and PPAR-α L162V carriers. No statistically significant differences were observed for other genes. LIPC C-514T and PPAR-alpha L162V carriers could benefit from a plant sterol supplement to ameliorate hypercholesterolemia.

Genomic Influence in the Prevention of Cardiovascular Diseases with a Sterol-Based Treatment.

Raised serum cholesterol concentration is a well-established risk factor in cardiovascular disease. In addition, genetic load may have an indirect influence on cardiovascular risk. Plant-based sterol-supplemented foods are recommended to help reduce the serum low-density lipoprotein cholesterol level. The objective was to analyse the influence of different polymorphisms in hypercholesterolemia patients following a dietary treatment with plant sterols. A randomised double-blind cross-over controlled clinical trial was carried out in 45 people (25 women). Commercial milk, containing 2.24 g of sterols, was ingested daily during a 3-week period, and then the same amount of skim milk, without sterols, was consumed daily during the 3-week placebo phase. Both phases were separated by a washout period of 2 weeks. At the beginning and end of each phase, blood draws were performed. Genes LIPC C-514T and APOA5 C56G are Ser19Trp carriers and greatly benefit from sterol intake in the diet. LIPC C-514T TT homozygous carriers had lower low-density lipoprotein cholesterol (LDL-c) levels than CC homozygote and CT heterozygote carriers after the ingestion of plant sterols (p = 0.001). These two genes also showed statistically significant changes in total cholesterol levels (p = 0.025; p = 0.005), and no significant changes in high-density lipoprotein (HDL) cholesterol levels (p = 0.032; p = 0.003), respectively. No statistically significant differences were observed for other genes. Further studies are needed to establish which genotype combinations would be the most protective against hypercholesterolemia.

[Not Available]. / Aspectos nutricionales, antropométricos y psicológicos en gimnasia rítmica.

Introducción: existen alteraciones frecuentes en la alimentación de la población infantil femenina, y especialmente en atletas de deportes estéticos por la presión ejercida para mantener un cuerpo.Objetivos: evaluar los aspectos nutricionales, antropométricos y la percepción del peso de niñas que realizan gimnasia rítmica frente a un grupo control.Métodos: estudio descriptivo comparativo. Se compararon 25 niñas gimnastas con 25 niñas no gimnastas (control). Se realizó una valoración antropométrica, mediante protocolo ISAK, y nutricional, mediante un registro dietético de siete días; así como una valoración cuantitativa y cualitativa de la ingesta alimentaria, mediante el software DIAL. Se rellenó un cuestionario de hábitos y sobre la percepción de su peso corporal.Resultados: los datos antropométricos no presentaron diferencias significativas entre ambos grupos, excepto en los pliegues cutáneos y el porcentaje de grasa, el cual era estadísticamente inferior en gimnastas. La ingesta energética (1.413 ± 283 Kcal/día) de las gimnastas era inferior a la recomendada por la Food and Nutrition Board de acuerdo a su edad. La distribución de los macronutrientes cumplía con los valores normales establecidos (10-30% proteínas, 45-65% hidratos, 20-35% grasas). El 32% de las gimnastas y el 36,4% de las niñas control consideraron que les gustaría pesar menos.Conclusión: teniendo en cuenta la intensa actividad de las gimnastas, sus requerimientos energéticos deberían ajustarse a ello, ya que esto contribuirá a su desarrollo y crecimiento y a una mejor ejecución del ejercicio. En la muestra estudiada, el consumo de alimentos de las gimnastas se aleja de una alimentación equilibrada. No se observaron comportamientos diferentes en la percepción del peso entre ambos grupos.

[Not Available]. / Doble efecto en hombres frente a mujeres de la ingesta de antibióticos y la obesidad: una muestra de 29.904 sujetos españoles.

Introducción: recientemente ha surgido el interés por el posible papel de la microbiota intestinal como agente potenciador del rápido aumento que se está observando en el aumento de la prevalencia de obesidad en todo el mundo.Objetivos: relacionar las modificaciones que puede ocasionar el consumo de antibióticos en la microflora intestinal con la obesidad.Métodos: se extrajeron, de las Encuestas Nacionales de Salud de España, entre los años 2001 y 2011, las cifras de ingesta de antibióticos y la prevalencia (%) de obesidad en el mismo rango de edad, género y año. La media total de encuestados fue de 29.904 participantes.Resultados: se encontraron correlaciones significativas (p=0,09) en la asociación de la prevalencia de obesidad y la ingesta de antibióticos. Además, se objetivó que en el sexo masculino esta influencia es el doble que en el femenino.Conclusiones: los descubrimientos recientes en el campo de la microbiota intestinal y su relación con el huésped abren nuevos caminos en la comprensión de ciertas enfermedades inflamatorias y metabólicas, como la obesidad.

[Not Available]. / Programación nutricional del gusto y la tolerancia al picante.

Introducción: la tradición de la comida picante desempeña un papel muy importante en el gusto por este tipo de comida y su tolerancia. Las preferencias alimentarias muestran influencia genética y ambiental.Objetivos: estudiar la tolerancia y el gusto por el picante de tres poblaciones, y la influencia hereditaria y del ambiente.Métodos:se realizó una encuesta a 522 sujetos, de tres continentes (Asia, Europa y Latinoamérica) en tres idiomas (español, inglés y chino) a través de Internet. Se realizaron preguntas acerca de la tolerancia al picante, el gusto por los alimentos picantes, su uso, la edad de comienzo de consumo, el gusto del padre y de la madre y si ella lo consumía durante el embarazo y/o lactancia.Resultados: existe diferencia entre el gusto por el picante del hijo y el sexo (p < 0,001), la tolerancia (p < 0,001) y, solo en el sexo femenino, el gusto de la madre por el picante (p < 0,001), su consumo durante el embarazo (p < 0,001) y la lactancia (p = 0,005) y el gusto del padre por el picante (p = 0,003). Existe correlación entre el continente de residencia (p = 0,007) y de nacimiento (p = 0,012) y la tolerancia a los alimentos picantes.Conclusión: la influencia de los progenitores, el género y la composición corporal se relacionaron con gustos y tolerancias diferentes.

[Bad results obtained from the current public health policies and recommendations of hydration].

INTRODUCTION: Achieving an adequate intake of water is crucial within a balanced diet. For that purpose, dietary guidelines for healthy eating and drinking are an important consideration and need to be updated and disseminated to the population. AIM: We aimed to evaluate the liquid intake habits of a Mediterranean and Latin American population (Spain-Portugal and Mexico-Uruguay) and if they support the current recommendations of hydration by the EFSA. METHODS: A record of fluid intake was obtained from 1168 participants from 4 countries above; and then compared with current consensus about hydration 1600 mL/day (female) and 2000 mL/day (male). RESULTS: The average fluid intake slightly surpassed the recommended: mean of 2049 mL/day (2,223 mL in males, 1,938 mL in females). Portugal stood out due to its lower intake (mean of 1,365 mL/day). Water contributed the largest part to total fluid intake (37%) in all countries (mean of 1365 mL/day). Hot beverages (18%) and milk and derivates (17%) follow water in highest consumption. The 20% of males and only 0.3% of females knew recommendations of hydration, while 63.3% of males and 62% of females followed them. Only 8.4% of people who follow the recommendations know them. CONCLUSION: The people studied surpassed the recommendation, although majority they didn´t know it. Future research should examine actual beverage consumption patterns and evaluate if the current consensuses are correctly adapted to the population needs. Hydration's policies should be transmitted to the population for their knowledge and adequate compliance.

[Not Available]. / Efecto de esteroles vegetales en la reducción del colesterol plasmático: ensayo clínico, controlado, aleatorizado, cruzado y doble ciego.

Introducción: la hipercolesterolemia es uno de los principales factores de riesgo en la enfermedad cardiovascular. Los esteroles vegetales se han postulado como agentes reguladores y beneficiosos para el control de esta.Objetivo: analizar el efecto de los esteroles vegetales añadidos en una leche en la reducción del colesterol plasmático en adultos jóvenes.Métodos: ensayo clínico, controlado, aleatorizado, doble ciego y cruzado. Los esteroles (2,24 g diarios) fueron administrados en dos tomas de 350 ml de una leche comercial desnatada, durante dos periodos de 3 semanas, separados por una "fase de lavado" de 2 semanas, en el grupo experimental. Al grupo control se le administró la misma cantidad de leche desnatada, sin esteroles. Tanto al inicio como al final de cadaperiodo de intervención se extrajeron muestras sanguíneas. Se analizaron la composición corporal, hábitos de salud y los siguientes marcadores sanguíneos: perfil lipídico, hematológico, inflamación, etc.Resultados: se incluyeron 54 personas en el estudio con una edad media de 38,8 ± 7,3 años. La diferencia porcentual entre los marcadores basales y finales para el colesterol total, colesterol-LDL, colesterol-HDL, triglicéridos y colesterol no-HDL fueron del 9,73%, 12,5%, 1,9%, 3,15% y 13,2%, respectivamente. Se obtuvieron diferencias estadísticamente significativas entre el grupo experimental y el grupo control, para todos los marcadores analizados excepto para los triglicéridos.Conclusión: los esteroles vegetales suministrados en un alimento de consumo habitual, como la leche, pueden ser una estrategia terapéutica no farmacológica para el control de la hipercolesterolemia de alto interés sanitario.

[Chromium supplementation in patients with type 2 diabetes and high risk of type 2 diabetes: a meta-analysis of randomized controlled trials].

INTRODUCTION: Chromium is an essential trace mineral for carbohydrate and lipid metabolism, which is currently prescribed to control diabetes mellitus. Results of previous systematic reviews and meta-analyses of chromium supplementation and metabolic profiles in diabetes have been inconsistent. AIM: The objective of this meta-analysis was to assess the effects on metabolic profiles and safety of chromium supplementation in type 2 diabetes mellitus and cholesterol. METHODS: Literature searches in PubMed, Scopus and Web of Science were made by use of related terms-keywords and randomized clinical trials during the period of 2000-2014. RESULTS: Thirteen trials fulfilled the inclusion criteria and were included in this systematic review. Total doses of Cr supplementation and brewer's yeast ranged from 42 to 1,000 µg/day, and duration of supplementation ranged from 30 to 120 days. The analysis indicated that there was a significant effect of chromium supplementation in diabetics on fasting plasma glucose with a weighted average effect size of -29.26 mg/dL, p = 0.01, CI 95% = -52.4 to -6.09; and on total cholesterol with a weighted average effect size of -6.7 mg/dL, p = 0.01, CI 95% = -11.88 to -1.53. CONCLUSIONS: The available evidence suggests favourable effects of chromium supplementation on glycaemic control in patients with diabetes.
