Exploring human breast milk composition by NMR-based metabolomics

The human breast milk is considered to be the perfect food for infants, specifically adapted to their needs. Changes in lifestyle and environment may impact on breast milk composition. This study was aimed at comparing the nutrients composition in breast milk in postpartum women in urban and sub-urban areas in Rivers State. The cross-sectional study was conducted among 59 postpartum subjects between 0 and 10days of child delivery in each group. Sampling was done through a simple random sampling method. Human breast milk was collected by means of a manual breast pump for the analysis of carbohydrate, protein and lipid using ClegAnthrone Method, Kjedahl Method and Soxhelt Extraction Method respectively. The results revealed that carbohydrate level was 6.1±0.5% in urban group and 5.0±0.1% in sub-urban group which was statistically significant (t-value=2.2; p-value=0.04). Protein level was 3.5±0.6% in urban group and 3.9±0.3% in sub-urban group which was statistically non-significant (t-value=0.6; p-value=0.57). Lipid level was 6.1±0.5% and 5.0±0.1% in urban and sub-urban groups respectively which was statistically non- significant (t-value=1.2; p-value=0.27). This study has revealed that differences in settlements (urban and sub-urban) have no impact on breast milk composition except in carbohydrate.

Mixed Model Analysis

AbstractThe variable content of human breast milk suggests that its routine fortification may result in sub-optimal nutritional intakes and growth. In a pragmatic trial, we randomised infants born below 30 weeks of gestation to either the intervention (Igp) of fortifying milk on measured composition according to birth weight criteria and postmenstrual age (PMA) or our routine practice (RPgp) of fortifying on assumed milk composition to target 3·8–4·4 g protein/kg per d and 545–629 kJ/kg per d. Milk composition was measured using the MIRIS® Human Milk Analyser. Percentage fat mass (%FM) was measured using PEA POD (COSMED). The effects of macronutrient intakes and clinical variables on growth were assessed using mixed model analysis. Mean measured protein content (1·6 g/100 ml) was higher than the assumed value (1·4 g/100 ml), often leading to lower amounts of fortifier added to the milk of intervention infants. At discharge (Igp v. RPgp), total protein (3·2 (sd 0·3) v. 3·4 (sd 0·4) g; P=0·067) and energy (456 (sd 39) v. 481 (sd 48) kJ; P=0·079) intakes from all nutrition sources, weight gain velocity (11·4 (sd 1·4) v. 12·1 (sd 1·6) g/kg per d; P=0·135) and %FM (13·7 (sd 3·6) v.13·6 (sd 3·5) %; P=0·984) did not significantly differ between groups. A protein intake >3·4 g/kg per d reduced %FM by 2 %. Nutrition and growth was not improved by targeting milk fortification according to birth weight criteria and PMA using measured milk composition, compared with routine practice. Targeting fortification on measured composition is labour intensive, requiring frequent milk sampling and precision measuring equipment, perhaps reasons for its limited practice. Guidance around safe upper levels of milk fortification is needed.

And Function

Human breast milk (HBM) is not only an indispensable source of nutrients for early human growth and development, supplying components that support infant growth and development, but also contains various essential immunologic components with anti-infectious activities and critical roles in the formation of immunity. It is also known that HBM contains its own unique microbiome, including beneficial, commensal, and potentially probiotic bacteria, that can contribute to infant gut colonization. In addition, HBM-derived extracellular vesicles, exosomes, and microRNA are attracting increasing interest for their potential to transfer to the infant and their role in infant development. In this article, we examine some of the various constituents in HBM and review the evidence supporting their associated health effects and their potential applications in human health.

Maternal Dietary Intake

Abstract Introduction: Human breast milk is the best source of nutrition in early life, particularly during the first six months. Nevertheless, human breast milk composition is variable and more insight in the exact factors contributing to this variability is warranted. In this review, we explored the impact of maternal dietary intake and nutritional status (e.g., anthropometric measures, body mass index, bioimpedance) on human milk macronutrient composition. Method: PubMed, Scopus and Cochrane were systematically searched till November 2019. Results: In total, 4946 publications underwent title-abstract screening; 101 publications underwent full-text screening. Eventually, 50 publications were included in this review, investigating either associations between maternal dietary intake (n=29) and/or maternal nutritional status (n=29), and macronutrient composition of human breast milk. Reported energy composition ranged from 51-72 kcal/dl, and 67% and 54% of the studies reported associations between with maternal nutritional intake and status, respectively. Protein content ranged from 0.8-3.3g/dl and four studies suggested a negative association with nutritional status. Fat content ranged from 2.1- 9.8g/dl, and 68% of the studies reported positive associations with nutritional status. Carbohydrate content ranged from 5.8-7.5g/dl, and 67% of the included studies did not report an association between intake or status. Conclusion: Literature investigating associations of maternal dietary intake and nutrition status with breast milk composition of macronutrients and energy content is diversified, both in terms of used methodology as well as results. Further studies using well defined and standard parameters are essential to aid the formulation of scientific recommendations.

Activation Pathway

Neonatal necrotizing enterocolitis (NEC), which is a disease with a poor prognosis, is considered to be caused by the coincidence of intestinal ischemia-reperfusion injury and systemic inflammation due to the colonization of pathogenic bacteria. Interleukin (IL)-8, a proinflammatory cytokine, plays an important role in the pathophysiology of NEC. It was recently reported that IL-1β activates the IL-8 gene by regulating the transcriptional nuclear factor κB (NF-κB) signaling pathways in intestinal cells. The protective role of maternal milk in NEC pathogenesis has been reported in both human and animal studies. In this study, we show that human breast milk dramatically suppressed the IL-1β-induced activation of the IL-8 gene promoter by inhibiting the activation pathway of NF-κB. Moreover, we also show that human breast milk induced the production of IκBα. These results suggest that human breast milk could be protective and therapeutic in neonates with NEC by inhibiting the activation pathway of NF-κB.

25 Hydroxyvitamin D

Background: Breast milk is considered the optimal source of nutrition during infancy. Although the vitamin D concentration in human breast milk is generally considered poor for infants, vitamin D in breast milk is an important source for exclusively breastfed infants. Increases in vitamin D insufficiency and deficiency in lactating mothers may reduce vitamin D concentrations in breast milk. This study aimed to compare vitamin D and 25-hydroxyvitamin D (25OHD) concentrations in breast milk collected in 1989 and 2016–2017 and simultaneously analyze them with liquid chromatography-tandem mass spectrometry (LC-MS/MS); the association between the lifestyle of recent lactating mothers (2016–2017) and vitamin D status in human breast milk was also evaluated. Method: Lactating mothers were recruited from three regions of Japan in 1989 (n = 72) and 2016–2017 (n = 90), and milk from 3–4 months was collected in summer and winter. The samples were strictly sealed and stored at −80℃ until measurement. Breast milk vitamin D and 25OHD concentrations were analyzed by LC-MS/MS. Vitamin D intake, sun exposure, and sunscreen use of the lactating mothers in 2016–2017 were assessed. Results: Both vitamin D and 25OHD concentrations in breast milk were higher in the summer regardless of the survey year. Significantly lower vitamin D and 25OHD concentrations were observed in 2016–2017 compared with 1989 in summer, but no survey year difference was observed in winter. The stepwise multiple regression analyses identified season, daily outdoor activity, and suntan in the last 12 months as independent factors associated with vitamin D3 concentrations. Conclusion: The results suggest that low vitamin D status in recent lactating mothers may have decreased vitamin D and 25OHD concentrations in breast milk compared with the 1980s. These results are helpful for developing public health strategies to improve vitamin D status in lactating mothers and infants.
