The contents of some elements in nuts and commercial dietary wheat brans were evaluated. In nuts and TDF residues, Ca, Mg, Zn, Fe and Cu were determined. In commercial bran-based foods produced for five years, toxic (Pb and Cd) and two nutritionally important (Cu and Zn) metals were determined. The percentage of elements in fiber varied significantly among fiber sources. The content of toxic metals in the dietary wheat bran-based products investigated is very low (0.074 mg/kg for Cd and 0.161 mg/kg for Pb). Regarding the samples of dietary wheat bran, a significant variation during the time is observed only for Cd content.

Abstract
The contents of some elements in nuts and commercial dietary wheat brans were evaluated. In nuts and TDF residues, Ca, Mg, Zn, Fe and Cu were determined. In commercial bran-based foods produced for five years, toxic (Pb and Cd) and two nutritionally important (Cu and Zn) metals were determined. The percentage of elements in fiber varied significantly among fiber sources. The content of toxic metals in the dietary wheat bran-based products investigated is very low (0.074 mg/kg for Cd and 0.161 mg/kg for Pb). Regarding the samples of dietary wheat bran, a significant variation during the time is observed only for Cd content.
