Social Media for Nutrition Education-A Randomized Controlled Trial to Promote Fruit and Vegetable Intake in a University Setting: "The University of Valladolid Community Eats Healthy" Study.

Social media- and internet-based interventions are nowadays widely used tools in health interventions. Although evidence of their effectiveness is still low, their applications could be very promising due to their affordability and wide reach. The current paper aims to evaluate the effectiveness of an intervention program, "The University of Valladolid Community Eats Healthy" (UVEH), to increase fruit and vegetable (FV) intake in adults from the University of Valladolid (U.

A survival study was conducted on 157 patients (46.

Food Safety through Natural Antimicrobials.

Microbial pathogens are the cause of many foodborne diseases after the ingestion of contaminated food. Several preservation methods have been developed to assure microbial food safety, as well as nutritional values and sensory characteristics of food. However, the demand for natural antimicrobial agents is increasing due to consumers' concern on health issues.

Bioelectrical impedance vector values in a Spanish healthy newborn population for nutritional assessment.

Bioelectrical impedance vector analysis in obese and overweight children.

Introduction: BMI is the most commonly used indicator to evaluate overweight and obesity, but it cannot distinguish changes in body composition. Over recent years, it has been demonstrated that bioelectrical impedance analysis (BIA) is a more accurate method for analyzing body composition. Bioelectrical impedance vector analysis (BIVA) has revealed its effectiveness as an indicator of nutritional status and hydration.

Introducción: la alimentación de los jóvenes universitarios se aleja cada vez más de la dieta mediterránea (DM). El binomio alimentación-actividad física es fundamental para mantener un adecuado estado de salud.Objetivo: comparar la ingesta en un grupo de estudiantes universitarios deportistas frente a otro que no realiza deporte habitualmente.

[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.

[PROPOSAL FOR A NEW FORMULA FOR ESTIMATING RESTING ENERGY EXPENDITURE FOR HEALTHY SPANISH POPULATION].

Introduction: although there are precise and accurate techniques for estimating resting energy expenditure, like the indirect calorimetry (IC), daily practice needs faster, easier and cheaper methods as the predictive equations.

Objective: the aim of the study was to develop a new predictive equation for estimating resting energy expenditure (REE) for healthy Spanish population. Méthods: the REE of 95 healthy normal weighted volunteers was determined by indirect calorimetry (IC).

[Nutritional status assessment in Geriatrics: Consensus declaration by the Spanish Society of Geriatrics and Gerontology NutritionWork Group].

Ongoing population ageing is one of the factors influencing the increase in the prevalence of undernutrition, as elderly people are a vulnerable group due to their biological, psychological and social characteristics. Despite its high prevalence, undernutrition is underdiagnosed in the geriatric sphere. For this reason, the aim of this consensus document is to devise a protocol for geriatric nutritional assessment.

Body mass index and waist circumference are not good surrogate indicators of adiposity in psychogeriatric patients.

Objective: to assess the utility of body mass index (BMI) and waist circumference (WC) as surrogate indicators of adiposity with respect to the total body fat estimated with bioimpedance analysis in psychogeriatric patients.

Methods: Anthropometric and hand-to-foot bioimpedance measurements were performed according to standard procedures in a sample of 128 psychogeriatric patients (87 males, 41 females). WC cutoffs proposed by the International Diabetes Federation were used to define abdominal obesity.

Bioimpedance vector analysis and conventional bioimpedance to assess body composition in older adults with dementia.

Objective: Although dementia and nutritional status have been shown to be strongly associated, differences in body composition (BC) among older people with dementia have not yet been firmly established. The aim of this study was to assess BC through conventional and vector bioimpedance analysis (BIA and BIVA, respectively) in a sample of institutionalized older men with and without dementia, in order to detect dementia-related BC changes.

Methods: Forty-one institutionalized men ages ≥ 65 y (23 without dementia [CG] and 18 with dementia [DG]) were measured with BIA and interpreted with BIVA and predictive equations.

Background: A new analytical variation of bioelectrical impedance vector analysis (BIVA), called specific BIVA, has shown to be more accurate in detecting changes in fat mass than classic BIVA.

Objective: To compare classic and specific BIVA in order to identify which is more strongly associated with psycho-functional and nutritional indicators in a group of institutionalised elderly patients with dementia.

Subjects And Methods: Cross-sectional study.

Is an integral nutritional approach to eating disorders feasible in primary care?

Patients with eating disorders (ED) show alterations in both their behaviour and their intake of food, frequently presenting nutritional and somatic affectations. Besides the classical forms such as anorexia or bulimia nervosa, there has recently been an increase in atypical or incomplete forms of ED, such as binge eating. Primary care (PC) services form the central and closest nucleus of health care for the individual and the family, where ED occur and leave their mark.
