“…The process of mapping analytical concentrations to consumed foods was conducted using the same method as for Australian total diet studies 35,36 . Mapping can consist of direct mapping of concentrations to foods, direct mapping with factors applied or assigning a recipe.…”

“…Methods of data derivation were recorded together with details, such as label data source, where appropriate. The direct mapping with factors method allows the mapping of a food's analytical concentration to other relevant foods with an additional adjustment factor applied to account for food manufacturing or preparation practices such as dehydration or cooking in water 35 . For example, a conversion factor would be applied to the analytical value for powdered infant formula to derive a value for ready‐to‐drink infant formula 35 .…”

Background: Nearly one in four Australian adults is vitamin D deficient (serum 25-hydroxyvitamin D concentrations [25(OH)D] < 50 nmol L -1 ) and current vitamin D intakes in the Australian population are unknown. Internationally, vitamin D intakes are commonly below recommendations, although estimates generally rely on food composition data that do not include 25(OH)D. We aimed to estimate usual vitamin D intakes in the Australian population. Methods: Nationally representative food consumption data were collected for Australians aged ≥ 2 years (n = 12,153) as part of the cross-sectional 2011-2013 Australian Health Survey (AHS). New analytical vitamin D food composition data for vitamin D 3 , 25(OH)D 3 , vitamin D 2 and 25(OH)D 2 were mapped to foods and beverages that were commonly consumed by AHS participants.Usual vitamin D intakes (µg day -1 ) by sex and age group were estimated using the National Cancer Institute method. Results: Assuming a 25(OH)D bioactivity factor of 1, mean daily intakes of vitamin D ranged between 1.84 and 3.25 µg day -1 . Compared to the estimated average requirement of 10 µg day -1 recommended by the Institute of Medicine, more than 95% of people had inadequate vitamin D intakes. We estimated that no participant exceeded the Institute of Medicine's Upper Level of Intake (63-100 µg day -1 , depending on age group). Conclusions: Usual vitamin D intakes in Australia are low. This evidence, paired with the high prevalence of vitamin D deficiency in Australia, suggests that data-driven nutrition policy is required to safely increase dietary intakes of vitamin D and improve vitamin D status at the population level.

“…Habitat of plants and aquatic living organisms also was taken into consideration in mapping in order to minimize the possible differences in the heavy metal content that would result from different living and/or cultivating environments (80) . In the subsequent total diet studies using mapping method reflecting hydration and raw equivalence factors (82) based on the water content and macronutrient content of foods, the authors found 10~50% increase in exposure estimates depending on the chemicals (ubiquitous in foods or not) and the comprehensiveness of the TDS food list (39 , 80) .…”

Total Diet Study: For a Closer-to-real Estimate of Dietary Exposure to Chemical Substances

Recent amendment on the Food Sanitation Act in Korea mandated the Minister of Food & Drug Safety to secure the scientific basis for management and reevaluation of standards and specifications of foods. Especially because the current food safety control is limited within the scope of ‘Farm to Market’ covering from production to retail in Korea, safety control at the plane of true ‘Farm to Fork’ scope is urgently needed and should include ‘total diet’ of population instead of individual food items. Therefore, ‘Total Diet Study (TDS)’ which provides ‘closer-to-real’ estimates of exposure to hazardous materials through analysis on table-ready (cooked) samples of foods would be the solution to more comprehensive food safety management, as suggested by World Health Organization and Food and Agriculture Organization of the United Nations. Although the protection of diets from hazards must be considered as one of the most essential public health functions of any country, we may need to revisit the value of foods which has been too much underrated by the meaningless amount of some hazardous materials in Korea. Considering the primary value of foods lies on sustaining life, growth, development, and health promotion of human being, food safety control should be handled not only by the presence or absence of hazardous materials but also by maximizing the value of foods via balancing with the preservation of beneficial components in foods embracing total diet. In this regard, this article aims to provide an overview on TDS by describing procedures involved except chemical analysis which is beyond our scope. Also, details on the ongoing TDS in Korea are provided as an example. Although TDS itself might not be of keen interest for most readers, it is the main user of the safety reference values resulted from toxicological research in the public health perspective.

The core-food (CF) approach, first adopted in the United States in the 1980s, has been widely used by many countries to assess the exposure to dietary hazards at a population level. However, the reliability of exposure estimates (C × CR) depends critically on sampling methods designed for the detected chemical concentrations (C) of each CF to match with the corresponding consumption rate (CR) estimated from the surveyed intake data. In order to reduce the uncertainty of food matching, this study presents a sampling design scheme, namely the subsample method, for the 2016 Taiwan total diet study (TDS) on veterinary drugs. We first combined the four sets of national dietary recall data that covered the entire age strata (1-65+ years), and aggregated them into 307 CFs by their similarity in nutritional values, manufacturing and cooking methods. The 40 CFs pertinent to veterinary drug residues were selected for this study, and 16 subsamples for each CF were designed by weighing their quantities in CR, product brands, manufacturing, processing and cooking methods. The calculated food matching rates of each CF from this study were 84.3-97.3%, which were higher than those obtained from many previous studies using the representative food (RF) method (53.1-57.8%). The subsample method not only considers the variety of food processing and cooking methods, but also it provides better food matching and reduces the uncertainty of exposure assessment.
