Enfamil NeuroPro Study

This study is a randomized, double-blind, parallel-group study comparing breast milk to Enfamil Infant and Enfamil NeuroPro formulas. The central hypothesis of the study is that the addition of milk fat globule membrane and2'-Fucosyllactose (2'-FL) to infant formula plays a role in shaping the microbiota in a manner similar to the microbiota of breastfed infants. To test this hypothesis, the investigators will explore longitudinal changes in the fecal microbiome from birth to 4 months of age in infants fed breast-milk, standard Enfamil Infant formula or Enfamil NeuroPro formula. Fecal samples will be collected at birth, and then monthly for 4 months. At the time of last collection one serum sample will be collected. The investigators will analyze basic growth parameters, fecal microbial community analysis by metagenomics, fecal metabolome by untargeted metabolomic analysis, and fecal and systemic indicators of inflammation and intestinal barrier function.
