Summary
The UK Total Diet Study (TDS) Update, published by the Food Standards Agency (FSA), provides surveillance data on the levels of nutrients, contaminants, and potentially harmful substances in the UK food supply and their estimated dietary intakes across population groups. The TDS is a long-running monitoring programme in which retail food samples representing the average UK diet are purchased, prepared as consumed, and analysed chemically. This update extends or revises previous estimates and informs FSA risk management and policy decisions regarding food safety and nutritional adequacy.
UK applicability
This report is directly and exclusively applicable to the UK context, providing nationally representative dietary exposure data that underpins FSA regulatory decisions, public health guidance, and compliance monitoring across England, Wales, and Northern Ireland.
Key measures
Dietary exposure estimates (µg/kg body weight/day or mg/day); nutrient and contaminant concentrations in food samples; comparison against tolerable daily intakes (TDIs) and dietary reference values (DRVs)
Outcomes reported
The study reports updated estimates of dietary exposure to a range of nutrients, contaminants, and other substances in the UK population, based on food consumption data and analytical testing of representative food samples. It assesses whether exposure levels raise any public health concerns relative to established dietary reference values and safety thresholds.
