Przeprowadzone badania wykazały niezadowalającą jakość żywieniową tłuszczu występującego w CRP pracowników niefizycznych. Zalecane normy dla zawartości tłuszczu były przekroczone o 50%. Ilość energii z tłuszczu w CRP z reguły była wyższa od 40% przy udziale energii z NNKT równym 1,9%.

Nutritional value of fats in a whole day's rations of persons of non-workmen's standing, was investigated. Fat content going beyond the recommended limit by more than 50%, and exceeding, as a rule, the fat energy portion by 40%, was found in rations under test. Predominant group was saturated and monounsaturated acids. Polyunsaturated acids content was low and amounted up 7% of total fatty acids sum. Saturated/mono- and polyunsaturated acids ratio was noted to depart considerably from that recommended at the P:S value = 0,13. The content of hypocholesteremic acids (essential fatty acids) was found to be several times lower than that of hypercholes- teremic-proaggregative acids which occurred in equivalent amounts. The lowest (from hitherto noted) energy portion from essential fatty acids (amounting to 1.9%) was observed in a whole day's rations of male subjects under investigation. Indices of fat nutritional value under test, were differentiated according to sex of subjects under investigation, and time od year on which experiments were carried out.
