“…This value is in good agreement with reports on mean percentage contributions of trans FAs to the FA composition of human milk in Europe [3,10,19,20,33,[39][40][41]. The mean values of trans FAs in mature milk reported for Poland (2.7%), Italy (Rome) (2.7%), Czech Republic (2.1%), France (2%) and Germany (2.4%) were all close to the value seen in our study.…”

The aim of this study was to determine the fatty acid composition and trans fatty acid and fatty acid contents of breast milk in Turkish women and to find the effect of breastfeeding mothers' diet on trans fatty acid and fatty acid composition. Mature milk samples obtained from 50 Turkish nursing women were analyzed. Total milk lipids extracts were transmethylated and analyzed by using gas liquid chromatography to determine fatty acids contents. A questionnaire was applied to observe eating habits and 3 days dietary records from mothers were obtained. Daily dietary intake of total energy and nutrients were estimated by using nutrient database. The mean total trans fatty acids contents was 2.13 +/- 1.03%. The major sources of trans fatty acids in mothers' diets were margarines-butter (37.0%), bakery products and confectionery (29.6%). Mothers who had high level of trans isomers in their milk consumed significantly higher amounts of these products. Saturated fatty acids, polyunsaturated fatty acids and monounsaturated fatty acids of human milk constituted 40.7 +/- 4.7%, 26.9 +/- 4.2% and 30.8 +/- 0.6% of the total fatty acids, respectively. The levels of fatty acids in human milk may reflect the current diet of the mother as well as the diet consumed early in pregnancy. Margarines, bakery products and confectionery are a major source of trans fatty acids in maternal diet in Turkey.

“…For example, in a Czech study, Roma women had significantly higher mean C18:1 t levels in their HM than the average Czech population (2.73 ± 1.88 vs. 2.09 ± 1.24; w/w%, mean ± SD). The difference was explained by the higher consumption of foods with higher TFA content among Roma women, including buns, biscuits, butter, hamburgers, potato chips, and other fried food ( 96 ). This was also corroborated in an Asian study, where Chinese women on a Western-style diet had significantly higher TFA levels in their HM compared to lactating women on a traditional Chinese diet ( 92 , 100 ).…”

It is well known that long chain polyunsaturated fatty acids (LCPUFAs) play an important role in neurodevelopment in the perinatal life. The most important source of these fatty acids is the diet, however, they can also be formed in the human body from their shorter chain precursors, the essential fatty acids. Since the WHO recommends exclusive breastfeeding for the first six months after birth, the exclusive source of these fatty acids for breastfed infants is human milk, which can be influenced by the mother’s diet. Unsaturated fatty acids can have either cis or trans configuration double bond in their chain with distinct physiological effects. Cis isomeric unsaturated fatty acids have several beneficial effects, while trans isomers are mostly detrimental, because of their similar structure to saturated fatty acids. Trans fatty acids (TFAs) can be further subdivided into industrial (iTFA) and ruminant-derived trans fatty acids (rTFA). However, the physiological effects of these two TFA subgroups may differ. In adults, dietary intake of iTFA has been linked to atherosclerosis, insulin resistance, obesity, chronic inflammation, and increased development of certain cancers, among other diseases. However, iTFAs can have a negative impact on health not only in adulthood but in childhood too. Results from previous studies have shown that iTFAs have a significant negative effect on LCPUFA levels in the blood of newborns and infants. In addition, iTFAs can affect the growth and development of infants, and animal studies suggest that they might even have lasting negative effects later in life. Since the only source of TFAs in the human body is the diet, the TFA content of breast milk may determine the TFA supply of breastfed infants and thus affect the levels of LCPUFAs important for neurodevelopment and the health of infants. In this review, we aim to provide an overview of the TFA content in human milk available in the literature and their potential effects on infant health and development.

“…Analýza 69 vzorků zralého MM ukázala, že obsah TFA v tuku (v našem případě se jedná o sumu 50 esterů MK, ale ve skutečnosti jich lze analyzovat mnohem více 32 ) MM se v průměru pohyboval kolem 0,9 ± 0,3 %, což je 3 -4x méně, než bylo naměřeno v českých studiích z let 2002 a 2007 (Dlouhý et al) 10,11 , kdy obsah TFA v tuku MM českých žen tvořilo v průměru 4,2 ± 1,9 a 3,13 ± 1,26 vs. 3,78 ± 1,88 hmotnostních procent.…”

“…Základním cílem národní studie byla analýza zralého mateřského mléka z pohledu obsahu a zastoupení jednotlivých typů mastných kyselin, se zaměřením na TFA, jejichž množství v dietě by mělo být minimalizováno. Ke stanovení minimálního počtu vzorků byl použit statistický výpočet (vzorec dle Hulley a kol., 2001) 26 , do něhož byly vloženy hodnoty z obdobné české studie stanovující TFA v MM českých žen(Marhol, Dlouhý a kol., 2007) 11 . Aby výsledky byly statisticky signifikantní na 5% hladině významnosti (zjištění průkazného rozdílu mezi koncentracemi ve starší a nové studii), bylo nutné získat minimálně 43 vzorků MM.Vzorky MM byly analyzovány na obsah 50 chemických individuí (viz příloha 1), tedy esterů mastných kyselin, v laboratoři plynové chromatografie SZÚ -CZVP v Brně.…”

The objective of the study was the analysis of mature breast milk (BM) of 69 participants in order to describe the content and composition of trans-fatty acids (TFA) in BM fat. Estimated dietary exposure to TFA in currently breastfeeding women and their children, or rather in the Czech population, is 3−4 times lower than more than a decade ago. While in 2002 and 2007 TFA measured in BM reached 4.2 and 3.1−3.8% out of the total BM fat content, respectively, nowadays it is only 0.9% on average. It was found that the WHO limits for trans-fatty acids (i.e. max. 1% of daily energy intake) were met in all participants. Average TFA intake in participants reached 0.3% of daily energy intake.
