HMOs are complex sugars found in breast milk, but infants do not digest them directly. Instead, HMOs serve as prebiotics by influencing the composition of the gut microbiome.
Previous studies have found that HMOs may also protect infants from disease-causing microbes. Approximately 150 types of HMOs are known, and mothers have unique combinations and concentrations of them in their breast milk, influenced in part by genetics and the types of HMO-processing enzymes they have.
The research team evaluated approximately 800 pairs of mothers and children in a Finnish study of child development. The researchers analyzed the content of HMOs in breast milk samples (collected when the children were 3 months old), among them two HMOs that are now added to some commercial infant formulas: 2'-fucosyllactose (2'FL) and lacto-N-neo-tetraose (LNnT).
Breast milk from mothers of taller and heavier infants and children tended to have less diverse HMO composition, higher concentrations of 2'FL and lower concentrations of LNnT. Breast milk from overweight and obese mothers also tended to have less diverse HMO composition, higher concentrations of 2'FL and lower concentrations of LNnT.
The authors noted that, although their study linked HMO composition with early childhood growth, it couldn't prove that variations in HMO patterns cause differences in children's growth. If additional studies confirm their findings, specific HMOs might one day provide a treatment for early childhood growth problems and obesity.
