Abstract [en]

Scope Milk fat globule membrane (MFGM) is an important component of milk that has previously been removed in the manufacture of infant formulas, but has recently gained attention owing to its potential to improve immunological, cognitive, and metabolic health. The goal of this study is to determine whether supplementing MFGM in infant formula would drive desirable changes in metabolism and gut microbiota to elicit benefits observed in prior studies. Methods and Results The serum metabolome and fecal microbiota are analyzed using H-1 NMR spectroscopy and 16S rRNA gene sequencing respectively in a cohort of Chinese infants given a standard formula or a formula supplemented with an MFGM-enriched whey protein fraction. Supplementing MFGM suppressed protein degradation pathways and the levels of insulinogenic amino acids that are typically enhanced in formula-fed infants while facilitating fatty acid oxidation and ketogenesis, a feature that may favor brain development. MFGM supplementation did not induce significant compositional changes in the fecal microbiota but suppressed microbial diversity and altered microbiota-associated metabolites. Conclusion Supplementing MFGM in a formula reduced some metabolic gaps between formula-fed and breastfed infants.
