Summary

Human milk plays an essential role in early life, yet its composition varies between mothers and even within the same mother, potentially influencing infant development. Maternal diet is one factor that may contribute to these differences. My PhD explored refined methods to better understand how maternal diet relates to human milk composition. Using detailed diet and milk analyses, I showed that dietary protein quality is reflected in specific milk proteins. I also found that several days of milk sampling are preferred to obtain a reliable average composition. Finally, I introduced a simple dried milk spot collection method that uses only a few drops of milk and is easy to store and transport. These advances will support more accurate and practical research on maternal diet and human milk, ultimately helping to build stronger scientific foundations for nutritional strategies that support healthy development in early life.
