Babies consuming increased amounts of breastmilk containing one particular micro-RNA molecule enjoyed a lower risk of skin, food, and respiratory allergies.  Penn State pediatricians studied 163 mothers who planned to breastfeed 4 months or more.  Samples of their breastmilk were collected over that time period and analysed for microRNA.

 

The analysis showed that the concentration of one particular microRNA, miR-375, was associated with significantly less allergy development in the babies.  No other microRNA measured showed such an association.  Levels of miR-375 increased the longer lactation continued and were notably higher in mothers with lower body masses.  

 

The takeaway from this for expectant mothers: if you want your baby to be allergy-free, keep your weight under control during pregnancy and plan on breastfeeding for as long as possible.
