[Comparative analysis of certain nutritional parameters of fat in food rations of various population groups. II. Composition of fatty acids]

Daily food rations showed a high content of saturated fatty acids, especially in males and females employed in white collar work. The content of monounsaturated acids was lower, and the per cent of energy from these acids complied with the present nutritional suggestions. The per cent of energy from polyunsaturated acids was below these suggestions. The studied food rations contained high amounts of fatty acids with properties favouring hyper-cholesterolaemia and platelet aggregation, while those causing hypocholesterolemia (unsaturated acids) were present in insufficient amounts. This was noted particularly in the food rations of working people and retired workers. The variance analysis showed statistical. Significance of the differences between the mean values of the studied parameters of fats of various population groups.
