Immunological effects of alpha-lactalbumin-enriched low-protein infant formula: A randomized controlled trial.

ABSTRACT:

Objectives

Breast-fed (BF) have lower risk of infections during infancy compared to those formula-fed (FF). A higher content of alpha-lactalbumin (α-lac) in breast milk, which may promote a more favorable gut microbiota, could be one reason. In this study, we evaluated whether increased concentration of α-lac in low-protein infant formula affects the immune response and the incidence of infections during infancy.

Methods

In a double-blinded randomized controlled trial, healthy-term infants (n = 245) received low-protein infant formulas with α-lac-enriched whey (α-lac-EW; 1.75 g protein/100 kcal, 27% α-lac) or casein glycomacropeptide-reduced whey (CGMP-RW; 1.76 g protein/100 kcal, 14% α-lac), or standard formula (SF; 2.2 g protein/100 kcal, 10% α-lac) from 2 to 6 months.
