Researchers compared the breast milk of mothers with babies born between 28, 37, 38 and after 38 weeks, they examined whether there were differences in the composition of the breast milks' microRNAs, snippets of RNA that affect gene expression and can be passed to the infant.
They discovered that there are differences in these microRNA profiles, and that the majority of the altered microRNAs influence metabolism, giving the microRNAs to babies could potentially impact how the newborn processes energy and nutrients.
Prematurely babies are at risk of different problems like failure to thrive and neurodevelopmental delays. They also tend to be born at a lower weight than term infants, premature babies have different nutritional needs than babies born at term.
The breast milk of mothers with premature babies has different amounts of microRNA than that of mothers with babies born at term, this improves growth and development in premature babies. Presently, there is no infant formula that have the special variations in microRNA profile for premature babies, breast milk is recommended for them because of their special needs.
