THE CONTENTS OF FREE AMINO ACIDS IN HUMAN MILK--A LONGITUDINAL STUDY / 营养学报

ABSTRACT

Free amino acids were analysed in 90 human milk samples during the first 6 weeks of lactation in Nanjin city. Glutatnic acid was the most and taurine was the second abundant component of the free amino acids in human milk. The free essential amino acids were highest in colostral milk and declined with advancing lactation. The possible roles of free amino acids in human milk for feeding infant in the first stage was discussed. The results of this study support that breast milk is beneficial for infants and suggest that the formulas should be supplemented with taurine.
