Trace element intake (zinc, manganese, copper, molybdenum, iodine and nickel) of humans in Thuringia and Brandenburg of the Fed. Rep. of Germany

Abstract

The daily dry matter intake of 56 test persons between 20 and 60 years of age from four geographic groups (Wusterhausen and Vetschau in Brandenburg; Jena and Bad Langensalza in Thuringia) was registered on 7 consecutive days by means of the duplicate method. The Zn, Mn, Cu, Mo, I and Ni content of food and beverage dry matter and the daily intake of these trace elements were determined. During the test period, the ration contained 24-29 mg zinc, 6.8-9.2 mg manganese, 1.9-2.6 mg copper, 0.17-0.22 mg molybdenum, 0.10-0.18 mg iodine and 0.36-0.68 mg nickel per kg dry matter. The adults consumed 6.7-11.0 mg zinc, 2.0-3.8 mg manganese, 0.54-0.92 mg copper, 47-89 micrograms molybdenum, 30-67 micrograms iodine and 111-256 micrograms nickel per day. The living area had an effect on the Mn, I and Ni intake. The higher dry matter intake resulted in a better trace element supply of male test persons. The copper, molybdenum and iodine requirement recommended by the WHO was not met.
