Bioavailability of cadmium from linseed and cocoa

A LOUS follow-up project


In Denmark and EU the exposure of cadmium from food is at a level that is relatively close to the Tolerable Daily Intake (TDI). This report describes an investigation of the bioavailability of cadmium in selected food items known to contain high levels of cadmium. The purpose was to provide data which can be used to further qualify the estimated exposure of the population to cadmium via food. The background for carrying out this investigation was the results from a survey of cadmium and cadmium compounds (Environmental Project no. 1471) conducted by the Danish EPA under the LOUS-review.

 The investigation was conducted as a feeding study in rats in combination with in-vitro studies simulating the conditions in the stomach of both rats and humans. The results of the investigation do, however, not provide a basis for changing the current advice to the public neither regarding the intake of whole or crushed linseed nor the intake of cocoa and chocolate.
