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. |
