| dc.description.abstract | The World Health Organization (WHO) and the European Food Safety Authority (EFSA) recognise Total Diet Studies (TDS) as an essential public health tool for assessing dietary exposure to beneficial and harmful substances through food. This study provides occurrence data for nine trace elements (As, Cd, Co, I, Mo, Pb, Se, Sn, and Sr) in representative foods consumed by the Portuguese population, using a harmonised TDS methodology. The study also fills previously missing data in the Portuguese Food Composition Database, strengthening its value for nutritional monitoring and exposure assessment. The results show that the lowest concentration of all trace elements were observed in the “Water and water-based beverages” group while the highest concentrations were found in “Fish, seafood, amphibians, reptiles, and invertebrates” (As, Cd, I, Pb, Se, Sr), “Sugar confectionery and water-based sweet desserts” (Co), “Legumes, nuts, oilseeds and spices” (Mo), and “Fruit and fruit products” (Sn). Importantly, all measured levels of trace elements were below the applicable legal limits, indicating that the analysed foods do not pose a risk for consumer health. Furthermore, the data can support risk assessment, regulatory decisions, and the development of public health policies related to trace element intake. These findings also facilitate comparisons with international TDS data, contributing to global understanding of dietary exposures. | eng |
