By Dr. Priyom Bose, Ph.D.Apr 30 2023Reviewed by Benedette Cuffari, M.Sc. Human milk is the ideal source of nutrition for infants, as it consists of bioactive factors and essential nutrients that support the growth, development, and health of the baby. Human milk oligosaccharides , a complex group of glycans, are abundantly found in human milk and have health-promoting factors.
It is important to understand how the variability in HMO profiles in pregnant women, along with other maternal factors, affect infant development. Several studies have shown that maternal genetic factors, particularly polymorphisms of the secretor and Lewis genes, are responsible for HMO profile variation. Other factors that cause these variations are lactation stage, environmental factors such as seasonality and geographic location, and maternal nutritional status.
