Understanding what's in breast milk and how it affects babies

The Multi-Omic Milk (MuMi) Study: Leveraging the IMiC Platform and the CHILD Cohort to study human milk as a biological system and understand its composition, determinants and impacts on child health

NIH-funded research University of Manitoba · NIH-11139437

Researchers are looking at many parts of breast milk from mothers and infants to see how milk ingredients relate to babies' growth, immunity, and allergy risk.

What this research studies

This project combines the International Milk Composition (IMiC) network and the Canadian CHILD birth cohort to treat breast milk as a complex biological system. Scientists will analyze milk from about 1,600 mother–baby pairs for sugars, fats, proteins, bacteria, and thousands of metabolites using modern multi-omic methods. They will link those milk measurements to child health records such as growth, allergy, and development outcomes. Advanced data science and AI tools will be used to understand how maternal, infant, and environmental factors shape milk and child health.

Who could benefit from this research

Good fit: Ideal candidates are breastfeeding mothers and their infants or young children who can provide milk samples and health information, especially families enrolled in or near the CHILD cohort.

Not a fit: Families who do not breastfeed or who seek immediate clinical treatment rather than contributing to research findings may not receive direct benefit from participation.

Why it matters

Potential benefit: If successful, this work could identify milk components that support healthy growth and lower allergy risk, helping to improve breastfeeding guidance and future nutrition strategies.

How similar studies have performed: Smaller studies have linked specific milk sugars, fats, and microbes to infant outcomes, but this large multi-omic, 1,600-pair approach is more comprehensive and partly novel.
