The need to study human milk as a biological system.

Area of Science:

• Human milk biology
• Systems biology
• Lactation science

Background:

• Human milk's complexity extends beyond nutritive components, involving interactions with maternal and environmental factors.
• Current research often analyzes single components, failing to capture the holistic biological function of human milk.
• Understanding human milk's systems biology is vital for infant development and maternal health, yet remains an unsettled science.

Purpose of the Study:

• To highlight the need for a paradigm shift in human milk research, moving towards a systems biology approach.
• To emphasize the critical importance of chronobiology and the milk matrix in understanding human milk's function.
• To advocate for research that unveils the multifunctionality of human milk components for maternal and child health.

Main Methods:

• The study proposes a conceptual framework for future research strategies.
• It calls for integrating technological advancements to study human milk's biological signaling pathways.
• Focus on a systems biology approach to analyze the interactions between milk components and infant development.

Main Results:

• Current analytical approaches are insufficient for understanding the full biological impact of human milk.
• A systems biology perspective is essential to grasp the interplay of factors influencing human milk's role in health.
• Advancements are needed to address the complex biological functions of human milk.

Conclusions:

• A shift to systems biology is critical for advancing human milk research and improving lactation and infant feeding practices.
• This approach will enhance strategies for maternal and child health, especially in undernourished and infectious environments.
• The proposed research agenda aims to transform the field of human milk biology with global policy implications.
