The heavy metal content of a typical Canadian diet.

Abstract

A program has been initiated at the Food and Drug Directorate to determine the heavy metal content of the typical Canadian diet. Data are presented showing the total daily intakes of the following elements: Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb and Zn. The present survey did not reveal the presence of any significant amounts of toxic elements and showed the adequacy of the diet to satisfy daily essential nutrient requirements.
