DETERMINATION OF DAILY INTAKE OF COPPER AND ZINC THROUGH FOOD BY TWO METHODS
DETERMINATION OF DAILY INTAKE OF COPPER AND ZINC THROUGH FOOD BY TWO METHODS

Summary/Abstract: The quantities of the essential elements copper and zinc through food were determined by two methods: 1. examination of 54 food products from the groups in one “consumer basket”, and calculation according to their representation in a meal; and 2. examination of a full-day meal. No difference has been observed in the determined daily intake for copper 1.388 (1.352) mg Cu/day, in relation to the recommended 1.3 mg Cu/day, and an insignificant difference has been observed in relation to a reduced daily intake for zinc 9.496 (10.248) mg Zn/day regarding the recommended 10.0-11.0 mg Zn/day; however, all this was within the limits of the reference data. The results obtained with the two methods for determining the daily intake of the elements of interest thorough food in the Army of the Republic of North Macedonia are equal. Hence, the choice of a method for determining the daily intake could be reduced to the selection of the second method (analysis of duplicate meals from a full-day meal) as a cheaper and faster method in contrast to the first method, which is very detailed, but takes a long time and is incomparably more expensive because it examines each food represented in the recipe for preparing all meals during the examination.
