“…The higher content of α-linolenic acid in donor human milk found in our study as compared with DHA may be possibly explained by the profile of milk donors, mostly represented by mothers who had delivered infants at term [ 19 ]. This finding is in accordance to previous studies showing higher LC-PUFA proportion in preterm milk compared to term human milk [ 35 , 36 ]. In term infants, DHA can be synthesized from α-linolenic acid, which is in contrast to the immature enzyme systems of preterm neonates in whom DHA cannot be synthesized de novo in sufficient amounts through this enzymatic pathway and negligible stocks of them exist in their adipose tissue [ 37 ].…”

Inadequate Content of Docosahexaenoic Acid (DHA) of Donor Human Milk for Feeding Preterm Infants: A Comparison with Mother’s Own Milk at Different Stages of Lactation

et al. 2021

A cross-sectional single-center study was designed to compare the fatty acids profile, particularly docosahexaenoic acid (DHA) levels, between milk banking samples of donor human milk and mother’s own milk (MOM) for feeding preterm infants born before 32 weeks’ gestation. MOM samples from 118 mothers included colostrum (1–7 days after delivery), transitional milk (9–14 days), and mature milk (15–28 days and ≥29 days). In the n-3 polyunsaturated fatty acids (PUFAs) group, the levels of α-linolenic acid (C18:3 n3) and DHA (C22:6 n3) showed opposite trends, whereas α-linolenic acid was higher in donor human milk as compared with MOM, with increasing levels as stages of lactation progressed, DHA levels were significantly lower in donor human milk than in MOM samples, which, in turn, showed decreasing levels along stages of lactation. DHA levels in donor human milk were 53% lower than in colostrum. Therefore, in preterm infants born before 32 weeks’ gestation, the use of pasteurized donor human milk as exclusive feeding or combined with breastfeeding provides an inadequate supply of DHA. Nursing mothers should increase DHA intake through fish consumption or nutritional supplements with high-dose DHA while breastfeeding. Milk banking fortified with DHA would guarantee adequate DHA levels in donor human milk.

“…Furthermore, as reported by Csapo et al, C4:0 and C12:0 were less than 0.2% of FA. Compared to the FA profile of human colostrum, ,, which is mainly constituted by SFA, the swine colostrum showed a higher percentage of MUFA and PUFA. However, the proportion of the three major FA present in swine colostrum (including palmitic, oleic, and linoleic acids), as well as the levels of n -6 PUFA (26.03%) and n -3 PUFA (1.97%) and the n -6/ n- 3 ratio (13.45), showed a high similarity with the FA composition of human colostrum. , Indeed, Qi et al, who investigated the FA composition of human breast colostrum, found that oleic acid (∼ 33%) was the most representative FA, followed by palmitic (∼ 20%) and linoleic (∼ 19%) acids.…”

Porcine colostrum lipid classes and fatty acids (FA) were characterized in 6 pools (from 69 samples) from 3 sow breeds (Italian Large White, Italian Landrace, and Italian Duroc) and different parity orders (only Large White). Triacylglycerols (TAG; 94.44 expressed as g/100 g of fat) were the most abundant lipid class, followed by diacylglycerols (DAG; 3.36 g/100 g of fat), free fatty acids (FFA; 0.98 g/100 g of fat), and cholesterol (0.84 g/100 g of fat). The main FAs found in swine colostrum were palmitic (27.29%, expressed as g/100 g of total FA), oleic (28.81%), and linoleic (23.39%) acids. Both the breed of sow and parity order affected the FA and lipid composition. The results suggest that the FA composition of swine colostrum is similar to that of human colostrum and could represent a new source of nutrients for human infants, after further assessment of hygienic and quality aspects. The swine model could be an opportunity for a better understanding of colostrum effects on newborns.

“…This finding is in accordance to previous ones showing higher long-chain PUFA proportion in preterm milk compared to full-term milk. [ 17 , 45 ] Furthermore, the above observation is of value, because preterm infants have limited capacity for elongating and desaturating linoleic and alpha-linolenic acids to long-chain PUFA and negligible stocks of them exist in their adipose tissue. [ 46 ] This finding may demonstrate the different response of the organism in view of a risk factor, increasing the quality of colostrum fat to cover specific needs of preterm infants.…”

Factors affecting human colostrum fatty acid profile: A case study

et al. 2017

The role of maternal colostrum to infant development has been extensively studied and presented. Among the main factors which contribute to breast milk composition are maternal diet, age and body mass index, parity, duration of pregnancy and stage of lactation. This study aims to investigate the potential impact of several factors including demographic (i.e. maternal age and nationality) on the colostrum fatty acid profile. Colostrum was collected the third day postpartum in a Greek maternity hospital. Certain lipid quality indices and fatty acid ratios were estimated and results were statistically processed. The main identified fatty acids were palmitic (C16:0), oleic (C18:1ω-9), and linoleic (C18:2ω-6) acids. Among fatty acids, saturated fatty acids predominated (47.61%), followed by monounsaturated fatty acids (39.26%), while polyunsaturated fatty acids had the lowest proportion (13.13%). Values of lipid quality indices were within the reported in the literature ranges. Maternal body mass index, nationality, age, mode of delivery, gender and fetal weight percentile were studied in respect to their potential influence on the fatty acid profile of colostrum fat. Results suggest that colostrum fatty acid profile was mainly dependent on maternal nationality and age rather than mode of delivery and maternal BMI. Regarding the effect of maternal nationality, significant differences were found for saturated and monounsaturated fatty acids. Of the most interesting findings is that colostrum fat from older (≥35 years) mothers had less saturated fat and more appropriate LQIs values. Finally, a reversed correlation was observed between the customized centile of the infants and the colostrum fat content.
