ABSTRACT

A total diet study (TDS) provides representative and realistic data for assessing the dietary intake of chemicals, such as contaminants and residues, and nutrients, at a population level. Reproducing the diet through collection of customarily consumed foods and their preparation as habitually eaten is crucial to ensure representativeness, i.e., all relevant foods are included and all potential dietary sources of the substances investigated are captured. Having this in mind, a conceptual framework for building a relevant food-shopping list was developed as a research task in the European Union's 7th Framework Program project, 'Total Diet Study Exposure' (TDS-Exposure), aimed at standardising methods for food sampling, analyses, exposure assessment calculations and modelling, priority foods, and selection of chemical contaminants. A stepwise approach following the knowledge translation (KT) model for concept analysis is proposed to set up a general protocol for the collection of food products in a TDS in terms of steps (characterisation of the food list, development of the food-shopping list, food products collection) and pillars (background documentation, procedures, and tools). A simple model for structuring the information in a way to support the implementation of the process, by presenting relevant datasets, forms to store inherent information, and folders to record the results is also proposed. Reproducibility of the process and possibility to exploit the gathered information are two main features of such a system for future applications.

ABSTRACT

Introducción: 'Globesity' es el término que la Organización Mundial de la Salud (OMS) emplea para denominar el progresivo aumento de la obesidad experimentado desde los últimos 40 años en los países desarrollados y cuyo contagio a los países en vías de desarrollo ha sido inevitable. Esta situación ha llevado a los gobiernos y organizaciones internacionales de todo el mundo a plantear estrategias destinadas a frenar dicha epidemia. Objetivo: Recopilar los conocimientos más actuales que se tienen de la relación entre los macronutrientes (en especial de la grasa y los sistemas de liberación de lípidos) y la secreción de péptidos gastrointestinales relacionados con la saciedad y saciación. Metodología: Se realizó una búsqueda bibliográfica basada en la combinación de términos MeSH en Medline (vía PubMed) y en LILACs mediante DeCS, así como una selección de otros artículos relacionados con la temática de la revisión. Resultados y discusión: Actualmente, numerosos laboratorios públicos y privados se encuentran investigando diversos ingredientes bioactivos relacionados con la regulación del apetito. Destacan los relacionados con la grasa ingerida y la forma en que esta puede ser tratada físicamente, sobre todo emulsiones y estructuras parecidas y su influencia sobre la saciedad y/o disminución de la sensación de hambre. Conclusiones: Estos ingredientes alimentarios se plantean como el futuro de los alimentos funcionales enfocados a la prevención de la ganancia de peso y ayuda a otras estrategias contra la obesidad (alimentarias, conductuales, etc...)

Introduction: 'Globesity' is the term that the World Health Organization (WHO) employs to define the growth of obesity in the world from the last 40 years which started in the developed countries and has been inevitably propagated to the developing ones. Governments and international organizations are aware of the problem and they are trying to implement measures to fight it. Aim: To analyze the current evidence in terms of studies about the relationship between macronutrients (especially fat and lipid release systems) and the secretion of gastrointestinal peptides that are involved with satiety and satiation. Methods: The search was conducted in Medline (via Pubmed) using different combinations of MeSH terms and in the database LILACs using 'DeCS'. A selection of another articles relevant to the review topic was also examined. Results and discussion: At present, there are several laboratories and industries developing novel bioactive ingredients aimed at the regulation of food intake, with emphasis on those related with fat intake and the different ways in which fat can be technologically processed in order to create structures able to enhance satiety and/or diminish hunger. Conclusion: These ingredients will be the future of functional foods focused on the prevention of weight gain and the support of other strategies against obesity (dietary, behavioral, etc…) (AU)

ABSTRACT

INTRODUCTION: "Globesity" is the term that the World Health Organization (WHO) employs to define the growth of obesity in the world from the last 40 years which started in the developed countries and has been inevitably propagated to the developing ones. Governments and international organizations are aware of the problem and they are trying to implement measures to fight it. AIM: To analyze the current evidence in terms of studies about the relationship between macronutrients (especially fat and lipid release systems) and the secretion of gastrointestinal peptides that are involved with satiety and satiation. METHODS: The search was conducted in Medline (via Pubmed) using different combinations of MeSH terms and in the database LILACs using "DeCS". A selection of another articles relevant to the review topic was also examined. RESULTS AND DISCUSSION: At present, there are several laboratories and industries developing novel bioactive ingredients aimed at the regulation of food intake, with emphasis on those related with fat intake and the different ways in which fat can be technologically processed in order to create structures able to enhance satiety and/ or diminish hunger.
