Abstract

The World Health Organization (WHO) has been encouraging the Total Diet Study (TDS) since WHO considered this study to be the most adequate method to estimate the dietary intakes of contaminants and nutrients of countries or populations on a large-scale. TDS is normally based on the evaluation of food samples representing a Market Basket. Since 1961 several TDS have been performed in many countries, but Brazil has not yet presented official results of its TDS. In 2009 a TDS was performed for a PhD thesis at IPEN-CNEN/SP that presented a Market Basket using data from the POF 2002-2003 National Household Food Budget Survey of the Brazilian Institute for Geography and Statistics (IBGE). In this study the intake of essential and toxic elements in 30 food groups of a Market Basket of São Paulo State were evaluated. However there were some limitations to the development of the first TDS in Brazil. The Market Basket presented restricted number of the household consumed foods (about 72% of the total food), and did not inclued outside household consumed foods. Albeit these limitations, the TDS provided important information about the analyzed foods, which suggested the continuity of the study in Brazilian TDS. Therefore, this research project proposes to carry out an updated TDS based on the POF 2008-2009 data to evaluate essential and toxic element dietary intakes, concerning the Southeast Region of Brazil, applying the methodology developed in the previous study, with some improvements: a) to update food consumption based on POF 2008-2009; b) to increase the number of food (100% of consumed food); c) to add food consumed outside the household, d) to analyze other important nutritional and toxicological elements: copper, manganese, magnesium, mercury, lead and so on.
