[Nutritional composition and nutritional claims of Canary Islands banana]. / Composición nutricional y declaraciones nutricionales del plátano de Canarias.

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.

A standardized, integral nutritional intervention and physical activity program reduces body weight in women newly diagnosed with breast cancer.

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.

A Dairy Product to Reconstitute Enriched with Bioactive Nutrients Stops Bone Loss in High-Risk Menopausal Women without Pharmacological Treatment.

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.

Consumption of Goat Cheese Naturally Rich in Omega-3 and Conjugated Linoleic Acid Improves the Cardiovascular and Inflammatory Biomarkers of Overweight and Obese Subjects: A Randomized Controlled Trial.

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.

Milk and Dairy Product Consumption and Bladder Cancer Risk: A Systematic Review and Meta-Analysis of Observational Studies.

Some studies have reported that milk and dairy product consumption reduces bladder cancer incidence, whereas others have reported null or opposite findings. This meta-analysis of 26 cohort and case-control studies has been conducted to pool the risk of the association between milk and dairy products and bladder cancer. A systematic search in MEDLINE, EMBASE, and the Web of Science (from inception to 30 April 2018) was conducted. Random-effects models were used to compute pooled estimates of RR for high or medium compared with low consumption of milk and dairy. Sensitivity analyses were conducted. Subgroup analyses were performed based on type of dairy, gender, geographic location, and type of study design. Random-effects meta-regression was used to evaluate other confounding factors. Overall, medium compared with low consumption was associated with lower pooled risk of bladder cancer for total dairy products (RR = 0.90; 95% CI: 0.81, 0.98), milk (RR = 0.90; 95% CI: 0.82, 0.98), and fermented dairy products (RR = 0.87; 95% CI: 0.79, 0.96). The inverse association for milk consumption was stronger in Asians (RR = 0.79; 95% CI: 0.59, 0.98) and in cohort design studies (RR = 0.85; 95% CI: 0.71, 0.99). Moreover, high compared with low consumption was significantly associated with a lower pooled risk for milk (RR = 0.89; 95% CI: 0.81, 0.98) and fermented dairy products (RR = 0.78; 95% CI: 0.61, 0.94). However, high compared with low consumption of whole milk was significantly associated with a higher risk (RR = 1.21; 95% CI: 1.04, 1.38). The statistical heterogeneity was considerable. In conclusion, the present meta-analysis suggests a decreased risk of bladder cancer associated with medium consumption of total dairy products and with medium and high consumption of milk and fermented dairy products. An increased risk of bladder cancer was observed with high consumption of whole milk. Interpretations of the results should be made with caution.

Milk and Dairy Product Consumption and Prostate Cancer Risk and Mortality: An Overview of Systematic Reviews and Meta-analyses.

Milk and dairy product consumption has been associated with an increase in prostate cancer risk; however, discrepancies have been observed in the literature. This first overview of systematic reviews and meta-analyses was carried out with the main objective of compiling and discussing the evidence generated to date related to milk and dairy product consumption and prostate cancer risk and mortality. A systematic search in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and the Web of Science (from inception to 30 April 2018) was conducted. The inclusion criteria were as follows: adult men, meta-analyses of longitudinal studies, dairy product consumption, and risk of prostate cancer or related outcomes. The AMSTAR2 checklist was used to evaluate methodological quality. The synthesis methods included dairy product exposure (high compared with low consumption or dose-response), dairy product type (total dairy products, milk, cheese, yogurt, and others), and prostate cancer outcomes (total, nonadvanced, and advanced prostate cancer and mortality) displayed in forest plots. Six meta-analyses were identified. These studies reported on the analysis of the 2 to 32 cohorts (up to 848,395 subjects/38,107 cases; 4-28 y of follow-up) and 2 case-control meta-analyses (12,435 subjects). The meta-analysis quality was valued as mostly "good" according to the AMSTAR2 criteria. All RRs of high compared with low consumption (dose-response) for total prostate cancer ranged from 1.68 to 1.09 (1.07 per 400 g/d) for total dairy products, 1.50 to 0.92 (1.06 to 0.98 per 200 g/d) for milk (whole, low-fat, and skim milk considered separately), and 1.18 to 0.74 (1.10 per 50 g/d) for cheese. RRs have decreased since the first meta-analysis. Statistical heterogeneity generates uncertainty in the observed results (up to I2 = 77.1%). In conclusion, although there are some data indicating that higher consumption of dairy products could increase the risk of prostate cancer, the evidence is not consistent. This review was registered with PROSPERO as CRD42018094737.
