Heterocyclic amines (HCAs) are contaminants in proteinaceous foods produced by cooking at high temperatures. This study was the first assessment of exposure to HCAs using the Korean total diet study. Twelve HCAs were analysed in 1,232 pooled samples using six isotope-labelled internal standards and ...

Based on the 6th China Total Diet Study (CTDS) conducted in 2016-2019, the occurrence of both legacy and novel brominated flame retardants (BFRs) was measured in animal-derived foods collected across China. Most BFRs could be frequently detected in food samples, indicating their ubiquity in the...

The aim of this study was to rank several chemical hazards present in one food item, namely infant formula. We first identified the substances potentially present in infant foods according to the results of the French infant Total Diet Study and to the available scientific literature. Second, we...

Human exposure to per- and polyfluoroalkyl substances (PFAS) through the US diet has not been well-characterized. Highly consumed foods are routinely monitored through FDA's Total Diet Study program. Portions of these samples were used to develop and validate a method for PFAS in a wide variety of...

Introduction: Mycotoxins are toxic metabolites produced by fungi that commonly contaminate foods. As recommended by the World Health Organization, total diet study (TDS) is the most efficient and effective way to estimate the dietary intakes of certain chemical substances for general populations....

Concentration levels of 26 polycyclic aromatic hydrocarbons and 20 trace elements were measured in dietary samples, in order to estimate the dietary intake and the potential exposure risk of the Greek population. Dietary samples were collected with the help of 30 volunteers inhabitants of Athens,...

Additional occurrence data are needed to better understand human exposure to per- and poly-fluoroalkyl substances (PFAS) from commercially available foods in the United States. The Food and Drug Administration's (FDA) Total Diet Study (TDS) collects foods that are both nationally and regionally...

As widespread contaminants, fumonisins (FBs) and ochratoxins (OTs) in food may cause public health threat. In this study, the dietary exposures to FBs and OTs in the Chinese general population were investigated by means of a total diet study (TDS) approach. A total of 672 composite dietary samples...

To estimate the mean dietary exposure to total As (tAs) and some arsenic species [inorganic arsenic (iAs), methylarsonic acid (MMAs) and dimethylarsinic acid (DMAs), and arsenobetaine (AsB)] across the entire Japanese population (≥1 year old), a national total diet study (TDS) based on composite...

Cancer cells acquire distinct metabolic preferences based on their tissue of origin, genetic alterations and degree of interaction with systemic hormones and metabolites. These adaptations support the increased nutrient demand required for increased growth and proliferation. Diet is the major...
