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. 14 Nojiri K, Kobayashi S, Higurashi S, et al. We conducted 2 trials of r-hPRL treatment. Further research will include breast milk macronutrient composition in relation to infant growth trajectories in the larger SKP2 sample, which will include a greater number of formula-fed infants.

Different studies determined the associations and effects of some maternal dietary intake of micro and macronutrients and its reflection in human milk. Carbohydrates are mainly lactose; several lactose-based oligosaccharides have been identified as minor components. 1, we found that the most common bias was related to random sequence generation and blinding. Up to the fifteenth day after childbirth. Its composition and inherent quality to protect the baby from various conditions makes it a clear winner.
