Totzauer M, et al. - In this multicenter, double-blind European trial, the researchers examined the impact of lower protein (LP) vs higher protein (HP) content in infant formula on body composition from 3 months to 6 years. For this analysis, healthy infants were randomly assigned to different protein content formulas (upper [HP] and lower [LP] limits of the European Union regulations in 2001) during the first year. In addition, breastfed infants were enrolled for reference values. In children from 2 to 6 years, infant formula with HP levels induced greater fat mass. Healthier body composition in early childhood could be obtained by lowering the protein content of infant formula.
