Total diet studies: a recipe for safer food

Total diet studies (TDS) are the primary sources of information on the levels of various chemical contaminants and nutrients in the diet. They can provide general assurance that the food supply is safe from certain chemical hazards and to develop priorities for possible risk management intervention. In addition, TDS results can be an indicator of environmental contamination by chemicals. TDS can also be used to assess the effectiveness of measures to reduce exposure of the population to chemical hazards. This brochure has been prepared by WHO to promote awareness of risk managers to the benefits of TDS.
