The Impact

Abstract An exclusive human milk diet (EHMD) has been shown to reduce health complications of prematurity in infants born weighing ≤1250 grams compared to cow milk-based diets. Accordingly, the number of available human milk (HM)-based nutritional products continues to increase. Newly available products, and those reportedly soon to enter the market include homogenized donor human milk (DHM) and homogenized HM–based fortifiers. Existing literature demonstrating the benefits of an EHMD, however, is limited to non-homogenized HM-based products. Herein, we summarize existing evidence on the impact of homogenization on HM, with a particular focus on changes to the macromolecular structure of the milk fat globule and its subsequent impact on digestion kinetics. We use these published data to create a conceptual framework for the potential implications of homogenized HM-based nutritional products on preterm infant health. Importantly, we underscore that the safety and efficacy of homogenized HM-based products warrant investigation.

The Impact

Abstract Background: Donor human milk (DHM) protects the health and development of premature infants but there has been little examination of the broader impact of an infant receiving it upon parental mental health. Breastfeeding and mental health are closely tied with women who experience breastfeeding difficulties or are unable to meet their own breastfeeding goals often experiencing feelings of guilt, sadness and anger, alongside an increased risk of postnatal depression. The aim of the current study was to explore how experience of receiving DHM for their baby affected the wellbeing of parents.Methods: UK parents of infants aged 0 – 12 months who had received screened DHM from a milk bank (typically on the neonatal unit or in some cases in the community) completed an online questionnaire exploring their experiences. The questionnaire included Likert scale items examining perceived impact upon infant health, own wellbeing and family functioning alongside open-ended questions exploring perceptions of how receiving DHM affected wellbeing.Results: Almost all of the 107 participants (women=102) agreed that receiving DHM had a positive impact upon infant health and development, their own mental and physical health, and their family’s wellbeing. Parents felt relieved that their infant was receiving DHM for health reasons but also due to the experience of being listened to, supported and having their infant feeding decisions facilitated. Receiving DHM helped mothers to process some of their emotions at not being able to breastfeed, in part because knowing their baby was being fed gave them the space to focus on recovery and bonding with their baby. Some parents did experience challenges, feeling guilty at receiving DHM, insecure that another woman was able to feed their baby when they could not, with some negative reactions from family. Although the impact of receiving DHM upon breastfeeding was not measured, some women who were working to build their own milk supply noted that it helped motivate them to continue.Conclusions: DHM may play an important role not only in protecting infant health and development but in supporting the mental health and wellbeing of mothers for whom their infant receiving human milk is important.

Feeding Tolerance

We aimed to evaluate if human milk-based fortifier (HMBF) affects human milk fat globule (MFG) size less than cow milk-based fortifier (CMBF), which may impact overall infant feeding tolerance. Measurements of donated human milk were performed before fortification as well as at 1 hour, 24 hours, and 48 hours after fortification with CMBF or HMBF. MFG size in each sample of fortified milk was measured by laser light scattering. MFG size in the fortified milks increased gradually over time. At 24 and 48 hours after fortification, MFG size in the milk with CMBF was larger than that in the milk with HMBF (4.8 ± 0.5 vs 4.3 ± 0.3 μm, p<0.01, 5.1 ± 0.7 vs 4.5 ± 0.4 μm, p = 0.03, respectively). HMBF is associated with less alteration of MFG size than CMBF. This may have an impact on feeding tolerance of very preterm infants.

Two individual glycoprotein components from human milk-fat-globule membranes (MFGM) has been purified by selectively extracting the membrane glycoproteins followed by lectin affinity chromatography and gel filtration on Sephadex G-200 in the presence of protein-disaggregating agents. The purified glycoprotein components, termed ‘epithelial-membrane glycoprotein’ (EMGP-155 and EMGP-39) have estimated molecular weights of 155 000 and 39 000 respectively, and yield a single band under reducing conditions on sodium dodecyl sulphate/polyacrylamide gel. EMGP-155 and EMGP-39 contain 21.0% and 7.0% carbohydrate by weight, with fucose (13.5%, 12.4%), mannose (3.7%, 6.2%), galactose (28.5%, 22.6%), N-acetylglucosamine (17.8%, 7.4%) and sialic acid (36.4%, 51.4%) of the carbohydrate moiety respectively. For both the glycoprotein components, aspartic and glutamic acid and serine are the major amino acid residues.

AbstractOne of main nutritional components in milk are fat. Fats are the main source of energy used by the body. The most important components are fatty acids (FA), which have important biological functions e.g. anti-inflammatory, anti-atherosclerotic, reducing blood pressure. What is more, milk fat in human diet shows health-promoting properties (1, 2). The aim of this study was to compare the fatty acids composition in selected mammals’ milk. A total of 84 milk samples of cow (Holstein-Frisian breed, n = 20), mare (Polish cold-blooded horse, n = 20); sheep (Kamieniecka breed, n = 12), goat (White goat breed, n = 12) were collected from small individual farms located in the north-eastern region of Poland. The samples of human milk (n = 20) were collected from women aged: 21–37, in the 2nd-4th month of lactation.The fatty acid composition was determined after the acids were transformed into methyl esters according to the IDF Standard method and gas chromatography using a Hewlett-Packard 6890 gas chromatograph with flame ionization detector. The average share of saturated FA (ΣSFA) in sheep, goat and cow milk fat were 77.5%, 75.5% and 67.7%, respectively, while in human and mare milk fat this value was about 47.0% ΣSFA. Human milk fat was characterized with the highest share of monounsaturated FA (ΣMUFA) 43.6%, while in the fat of other mammals this value was from 19.0 to 31.0%. The highest share of polyunsaturated FA (ΣPUFA; 22.0%) was found in mare milk. In human milk fat the value of ΣPUFA were higher (10%), than in milk of other mammals (3–5%). The lowest value of ΣSFA was observed in human and mare milk which could influence its health-promoting properties. The high share of other essential unsaturated FA indicates high dietary value of human milk. The share of fatty acids in mare milk similar to that in human milk makes it the most suitable in human nutrition.
