This paper is a summary of the Spanish Federation of Nutrition, Food and Dietetics Associations (FESNAD) and the Spanish Association for the Study of Obesity (SEEDO) consensus document on the role of diet in prevention and treatment of overweight and obesity. To prepare this document, and in order to achieve the maximum evidence level possible, a systematic review was made of all medical literature published between January 1, 1996 and January 31, 2011 (15 years). The obtained findings were catalogued by evidence level following the Scottish Intercollegiate Guidelines Network system, and recommendations were produced based on data collected. As a result, 65 evidences and 31 recommendations applicable to obese adults without any other pathological process were produced. Evidences and resulting recommendations are provided, and the most significant findings are discussed. This consensus document is intended to provide healthcare professionals with a reference tool that may help them design dietary strategies for prevention and treatment of overweight and obesity. © 2012 SEEN.

The present study is a consensus document of two Spanish scientific associations, FESNAD (Spanish Federation of Societies of Nutrition, Food and Dietetics Associations) and SEEDO (Spanish Association for the Study of Obesity), about the role of the diet in the prevention and treatment of overweight and obesity in adults. In this part of the document the methodology and the classification of levels of evidence are described. In order to reach the strongest evidence possible, a systematic review of 543 medical studies dealing with these issues published in the last 15 years (from January 1st 1996 to January 31st 2011) has been conducted. In the executive summary, along with the obtained evidences, a set of degree-classified recommendations are established. These recommendations could constitute a useful tool to design food guides addressed to the nutritional counseling for obesity and overweight treatment. Source

This article is the adapted version of the publication standards of the Actividad Dietética journal in the Position Paper of the Scientific Committee " 5 a day" with respect to the Consumption of fruit juices in the framework of a healthy diet. The position was approved at the Vth Scientific Committee Meeting held in Madrid on April 4th, 2009. The controversy that arose on the criteria and parameters for assessing fruit and/or vegetable juices within the " 5 a day" Scientific Committee itself has prompted the creation of this position paper to assess, justify and reach a consensus on including juices in the recommendations for consuming fruits or vegetables fostered by the " 5 a day" Association, as well as the declarations allowed on consumption. © 2010 AEBM, AEFA y SEQC.

Introduction: Caffeine and catechins contained in green tea may have a thermogenic effect favoring weight and body fat loss. The aim of this study is to evaluate the magnitude of the effect of green tea or its extracts (caffeine and catechins) on body weight and body composition. Material and methods: A systematic review and metaanalysis was conducted to determine the magnitude of the effect of green tea or its extracts on body weight (kg), body mass index (BMI) (kg/m2), fat mass (%), and waist and hip circumference (cm). We included studies published between 2000 and 2013, retrieved from PubMed/Medline with the following characteristics: randomized controlled trials (RCTs) of parallel groups (intervention and placebo), randomized, double-blind, and a minimum 12-week follow-up, in healthy individuals of either gender, 18 years or older, with a BMI of 25-40 kg/m2. Quality and risk of bias was assessed for every included study, and the statistical analysis was performed with the Crochrane Collaboration RevMan 5.1.6 software, according to the random effects model with a confidence interval of 95% (95%). It was established that the effect was statistically significant at p < 0.05, and the homogeneity of the studies was assessed using the I2 index. Results: The search strategy retrieved 154 studies, of which only five could be included in the quantitative analysis. The analysis revealed a not statistically significant mean difference (MD) in weight loss in the analyzed sample and subgroups: Asian individuals -0.81 kg (95% CI: -2.76 to 1.13; P = 0.41; I2 = 0%, n = 210), Caucasians -0.73 kg (95% CI: -3.22 to 1.75; P = 0.45; I2 = 0%; n = 91), as well as in the sample as a whole: -0.78 kg (95% CI: -2.31 to 0.75; P = 0.32; I2 = 0%; n = 301). No statistically significant decrease was revealed in BMI in the analyzed sample and subgroups: Asian individuals -0.65 (95% CI: -1.85 to 0.54; P = 0.29; I2 = 0%; n = 71), -0.21 Caucasians (95% CI: -0.96 to 0.53; P = 0.58; I2 = 22%; n = 91), as well as in the sample as a whole: -0.31 kg (95% CI: -0.88 to 0.27; P = 0.30; I2 = 0%; n = 162), nor for the waist circumference 0.08 cm (95% CI: -0.39 to 0.55; P = 0.73; I2 = 3%; n = 301) or hip (95% CI: -1.14 to 0.93; P = 0.85; I2 = 0%; n = 210). In the evaluation of the effect on the percentage of fat mass (FM%), MD was found not statistically significant for population subgroups: Asian individuals -0.76 (95% CI: -1.59 to 0.08; P = 0.08; I2 = 0%; n = 169), Caucasians -0.76 (95% CI: -2.22 to 0.70; P = 0.31; I2 = 36%; n = 93), but a small, although statistically significant, decrease in the overall effect was found -0.76 (95% CI: -1.44 to -0.09; P = 0.03; I2 = 0%; n = 260). Discussion: The statistically significant effect of green tea on the FM% of the entire sample was not clinically relevant, a fact also highlighted in the results of other meta-analysis. Conclusion of the authors: Green tea or gree tea extracts intake or its extracts exerts no statistically significant effect on the weight of overweight or obese adults. There is a small effect on the decrease in the percentage of fat mass, but it is not clinically relevant. Source


In the face of the growing use of weight-losing strategies as an alternative to conventional methods, the Revision, Study and Positioning Group of the Spanish Association of Dieticians-Nutritionists (GREP-AEDN) has decided to analyse these methods and to provide information on the degree of efficacy, reliability and/ or risk involved in their use, specifically of the Food Sensitivity Tests. By means of this document, the GREP-AEDN advises against the use of these tests based on blood tests as diagnostic evidence for treating obesity, as well as for detecting possible allergies and/or food intolerances. This position is based on the fact that neither these tests nor the dietary treatments prescribed following their results have been validated by the scientific community. Furthermore, by revising the positions of the most important clinical societies in the field of allergology and immunology, as well as the scientific studies on the matter mentioned in this document, the GREP-AEDN considers that undergoing the dietary treatment resulting from the results of these tests (mainly characterised by the restriction of food items) not only means a waste of money, but it can entail health hazards. © 2010 AEBM, AEFA y SEQC.
