Mother's Own Milk Versus Donor Human Milk: What's the Difference?

Area of Science:

• Neonatal nutrition
• Infant immunology
• Microbiology of human milk

Background:

• Mother's own milk (MOM) is crucial for preterm infant health, reducing complications.
• Donor human milk (DHM) is recommended when MOM is unavailable for very low-birth weight infants.
• DHM's composition differs from MOM due to donor factors and processing.

Purpose of the Study:

• To review the differences between MOM and DHM.
• To explore the potential health outcome effects of these differences.
• To discuss clinical implications and future research directions.

Main Methods:

• Literature review of studies comparing MOM and DHM.
• Analysis of nutritional, immunologic, and microbial components.
• Synthesis of findings on health outcomes and clinical practice.

Main Results:

• DHM processing (pasteurization) and donor lactation stage alter its nutritional and bioactive components.
• These alterations may impact the immunologic and microbial benefits compared to MOM.
• Significant differences exist in key components affecting preterm infant development.

Conclusions:

• The differences between MOM and DHM have significant clinical implications for preterm infants.
• Further research is needed to optimize DHM utilization and mitigate potential negative effects.
• Clinical practice should consider these differences when feeding preterm infants.
