The objective of this study was to examine the relation between the content of pentadecanoic acid C15:0 (PA) and heptadecanoic acid C17:0 (HA) in human milk and the type of the mothers' diet and determine the content of these fatty acids in infant formulas and follow-up formulas available on the market. Thirty-four, healthy mothers, aged 24-33 y were take part in the study. Mothers were classified according to their diet status into one of two groups: diet low in dairy products (15) and standard diet (19). Analyzed 12 differences infant formulas, 6 infant formulas and 6 follow-on formulas. In the group of women whose diet was Iow in dairy products, the PA content of human milk fat reached on average 0.195 ±0.017% of total fatty acids, and the HA content - 0.202 ±0.012%. In the group of women eating a standard diet, a statistically significant increase was observed in the PA and HA content of milk fat which on average reached: PA - 0.406 ±0.019% and HA - 0.360 ±0.015% of total fatty acids. It was concluded that in respect of human milk, PA and HA could be regarded as biomarkers of milk fat consumption by lactating women. From among 12 investigated infant formulas (IF) and follow-up formulas (FF) which are available in retail, PA of 0.63 to 0.98% and HA of 0.37 to 0.60% of total fatty acids was found in only 4 formulas which contain bovine milk fat. In IFs which, according to the manufacturer's statement, do not contain milk fat, PA content was from 0.04 to 0.07% and HA - from 0.02 to 0.08% of total fatty acids.

Badano zależność pomiędzy występowaniem w mleku ludzkim kwasów pentadekanowego C15:0 (PA) i heptadekanowego C17:0 (HA) a rodzajem diety matek oraz oznaczono zawartość kwasów PA i HA w preparatach do początkowego i następnego żywienia niemowląt, dostępnych w sprzedaży. Badaniu poddano mleko ludzkie uzyskane od 34 zdrowych kobiet w wieku 24-33 lata. Matki podzielono na dwie grupy zgodnie ze spożywaną przez nie dietą: grupę kobiet z dietą ubogą w tłuszcz mleka krowiego (N = 15) i grupę kobiet odżywiających się przeciętnie (N = 19). W grupie kobiet spożywających dietę ubogą w produkty mleczne zawartość PA w tłuszczu mleka ludzkiego wynosiła średnio 0,195 ±0,017% ogólnego składu KT, natomiast HA osiągało średnio 0,202 ±0,012%. W grupie kobiet odżywiających się w przeciętny sposób zawartość PA i HA w tłuszczu mleka była statystycznie istotnie wyższa i wynosiła średnio: PA 0,406 ±0,019%,
