Supplementation of milk formula with galacto-oligosaccharides improves intestinal micro-flora and fermentation in term infants.
BACKGROUND Oligosaccharides in human milk may protect infants by improving the intestinal micro-flora and fermentation . This study was to investigate effects of  infant formula milk consisting of galacto-oligosaccharide ( GOS ) on intestinal microbial population s and the fermentation characteristics in term infants in comparison with that of human milk . METHODS The test formula ( Frisolac H , Friesl and , Netherl and ) was supplemented with GOS at a concentration of 0.24 g/dl . Human milk and another formula without oligosaccharides ( Frisolac H , Friesl and , Netherl and ) were used as positive and negative control respectively . Growth , stool characteristics , and side effects of the recruited infants were recorded after 3 and 6 months ' follow-up , and the fecal species were collected for the analysis of intestinal micro-flora , short chain fatty acid ( SCFA ) and pH. RESULTS At the end of 3- and 6-month feeding period , intestinal Bifidobacteria and Lactobacilli were significantly increased in infants fed with GOS supplemented formula and human milk when compared with infants fed with negative control formula ; however , there was no statistically significant difference between GOS supplemented formula and human milk groups . Stool characteristics were influenced by the supplement and main fecal SCFA ( acetic ) , and stool frequency were significantly increased in infants fed with GOS supplemented formula and human milk , while the fecal pH was significantly decreased as compared with that of negative control ( P < 0.05 ) . Supplementation had no influence on incidence of side effects ( including crying , regurgitation and vomiting ) . CONCLUSIONS Supplementing infant formula with GOS at a concentration of 0.24 g/dl stimulates the growth of Bifidobacteria and Lactobacilli in the intestine and stool characteristics are similar to in term infants fed with human milk
