[Protein deficiency in hospital food. Possibilities of using protein preparations]

During a twenty days period, the daily supply of protein with the normal diet was investigated for thirty patients of an emergency station. The system of food distribution allowed precise weighing of each patient's portion. According to the calculation by the "kleine Nährwerttabelle" an average daily protein allowance of 12.4 kcal% at an average daily energy allowance of 2100 kcal with an average worth of material of 20 öS was found. The nitrogen loss accounted in the literature for different stress situations enables to calculate a far higher protein need. The use of protein preparations is discussed for satisfying the need. The possibility to use milk-protein for food preparations was tested. In a trial was found that 46.2% of the patients accepted the given protein-enriched soup. Thus the share of protein in total daily calories should be lifted from 12.4 kcal% to 14.6 kcal% spending only 4.44 öS more than before. Elevating the protein portion with normal food is possible only by spending multiple costs.
