Quantity and proximate composition of breast milk from Burmese mothers of low socioeconomic group at three stages of lactation were studied. Protein content (total N X 6.38) of breast milk at 1 to 4 months of lactation was significantly higher than that of 7 to 12 months but there were no significant differences in milk fat, lactose, and energy among three stages of lactation. No significant differences in proximate composition of breast milk were observed between well-nourished and malnourished groups. Potential milk output of mothers belonging to well-nourished group was significantly higher than the corresponding values for milk intake of infants.

Zinc (Zn) is one of the most prevalent and essential micronutrients, found in 10% of all human proteins and involved in numerous cellular enzymatic pathways. Zn is important in the neonatal brain, due to its involvement in neurotransmission, synaptic plasticity, and neural signaling. It acts as a neuronal modulator and is highly concentrated in certain brain regions, such as the hippocampus, and the retina.

Background: During lactation, maternal requirements for many nutrients increase due to the physiological demands of breast milk production, reflected in dietary recommendations. BMI is negatively associated with dietary quality postpartum, and 40% of women in Norway have pre-pregnancy overweight and obesity. Currently, there is limited data on dietary intake among lactating women in Norway and whether they meet nutritional requirements.

Here, we report that small extracellular vesicles (sEVs) in milk mediate the communication between bacteria and animal kingdoms, increase the divergence of bacteria in the intestine, and alter metabolite production by bacteria. We show that bovine milk sEVs select approximately 55,000 genomic variants in 19 species of bacteria from the murine cecum . The genomic variants are transcribed into mRNA.
