NDNS biomonitoring for exposure to food additives

Description

This research project aims to make progress towards a better understanding of actual UK consumer exposure to food additives. The aim is investigation of an approach for estimating exposure to food additives through measurement of biomarkers in biological samples taken as part of the National Diet and Nutrition Survey (NDNS). The FSA is currently working with a research partner to measure concentrations of biomarkers of food additives (specifically non-sugar sweeteners) in NDNS urine samples, using analytical chemistry techniques. Following completion of the analytical measurements, the FSA is seeking to commission further research to analyse and interpret the results, to make estimates of relative exposure to non-sugar sweeteners and to estimate dietary intake of the relevant non-sugar sweeteners from the urinary excretion of the corresponding biomarkers
