Dietary exposure assessment of substances in foods. The BfR MEAL study - the first German total diet study

The dietary exposure of a population to chemical substances is estimated based on representative consumption data and data on the occurrence of substances in foods. Consumption data in Germany for different age groups are provided by the National Nutrition Survey ll, VELS, EsKiMo and the ongoing KiESEL study. The data for the levels of substances in foods is currently obtained from the German food monitoring programme (Lebensmittel-Monitoring) and the German Food Composition Table (Bundeslebensmittelschlussel) and is not sufficient for a comprehensive evaluation of dietary exposure in Germany. More data is needed and, in particular, the range of analysed substances should be broadened to reduce the uncertainties of the exposure assessment. A representative data basis for concentrations of substances in foods will be established with the first German total diet study, called the BfR MEAL study. The study will markedly reduce major uncertainties in the dietary exposure assessment through its wide coverage of substances in food groups, the inclusion of prepared foods, the orientation on low measurement limits as well as the analysis of substances without a reliable data basis.
