| Description | Zinc is an essential trace mineral that has functions as part of about 300 different enzymes. As such, zinc plays a role in virtually all biochemical pathways and physiological processes (TALBOTT, 2003). Zinc associates with the hormone insulin in the pancreas, although it does not appear to play a direct role in insulin´s action. (LINDER, 1991;WHITNEY and ROLFES, 1993). Oysters are the richest source of zinc. Other foods high in zinc include red meat, poultry, shellfish, fortified breakfast cereals, whole grains, legumes, cooked greens, brewer´s yeast, and nuts (COLLINS, 2003). The evaluation of the 13 chosen sets of courses has been done in this research work. Sets have been taken from Military University of Ground Forces dinning hall in Vyškov. The trace elements were determined by chemical analysis (JUŘÍKOVÁ et al., 2004). In this paper is present only zinc content in these food. 1. Baked pork, dumpling and sauerkraut contain 3.0 mg of zinc. 2. Boiled beef boiled potatoes and mixed vegetables contain 4.6 mg of zinc. 3. Meat balls, potato purée and cucumber contain 2.2 mg of zinc. 4. Roasted pork, potato salad and tomato contain 2.8 mg of zinc. 5. Mince, boiled potatoes and sauerkraut contain 5.3 mg of zinc. 6.
