Total Diet Studies in Catalonia, Spain

2013
The first total diet study (TDS) in Catalonia was contacted between 2000 and 2002 with the objective of estimating the mean dietary exposures for different population cohorts by age and gender to the main environmental contaminants, which included heavy metals and a number of persistent organic pollutants (POPs), such as dioxins and PCBs.

The study of iodine in Chinese total diets

Science of The Total Environment, 1997
In this work, China was divided into four area groups according to their geographical positions and dietary habits. All foods were divided into 12 types and the iodine contents in various diets were determined using epithermal neutron activation analysis (NAA). The intakes for China were evaluated.

Evolution of approaches in conducting total diet studies

Journal of Applied Toxicology, 2012
ABSTRACTOne of the main routes of human exposure to contaminants is through food. To assess the health impact, it is necessary to determine the levels of contaminants in foods and evaluate the exposure estimates. Many countries regularly conduct total diet studies as a method of assessing the exposure of the population to various contaminants present ...

Revision of the Total Diet Study food list and diets

Journal of the American Dietetic Association, 1983
The foods and diets of FDA's Total Diet Study have been revised according to current food consumption patterns. A representative subset of 234 foods, selected from aggregated NFCS and NHANES II data, is collected and analyzed by the Kansas City Field Office Laboratory for 11 essential minerals and more than 120 chemical contaminants.

Total Diet Studies—Examples from Sweden

Journal of Food Composition and Analysis, 2000
This paper gives a brief overview of market basket and duplicate portion studies carried out in Sweden during the last decades. Most of the studies have included mineral elements with an emphasis on the assessment of the dietary exposure of toxic elements such as lead and cadmium.

Total Diet Studies in the Indian Context

2013
The food safety concerns in India are different from other countries due to the fact that dietary habits are so different. The foremost food safety concern among Indians is food adulteration. The concern for contaminants like pesticide residues and toxic metals in food is a more recent phenomenon.

Sampling variability and uncertainty in total diet studies

The Analyst, 2011
Here, the uncertainty budget for a total diet study (TDS) was clarified by separating the total measurement uncertainty into the uncertainty arising from the compositional heterogeneity of food items between cities (referred to as inter-city variance), the heterogeneity of food items within cities (intra-city variance), and the chemical analysis of the

Total Diet Studies—United Kingdom’s Experience

2013
The Total Diet Study (TDS) is an important part of the United Kingdom (UK) Government surveillance programme for chemicals in food and has been carried out on a continuous basis since 1966. Results from the UK TDS are used, together with food consumption data from various surveys, including the UK National Dietary and Nutrition Survey, to estimate ...

New Zealand’s Experience in Total Diet Studies

2013
The New Zealand total diet study (NZTDS) is an important exposure assessment tool for New Zealand’s food regulatory authority, which can identify potential exposure concerns and monitor trends in dietary exposure. The NZTDS provides essential scientific inputs to regulatory activities that range from risk communication to setting specific food control ...
