No statistically significant subgroup differences were found according to infant risk of allergy or type of infant feed .
There is some evidence that a prebiotic supplement added to infant feeds may prevent eczema .
It is unclear whether the use of prebiotic should be restricted to infants at high risk of allergy or may have an effect in low risk population s ; or whether it may have an effect on other allergic diseases including asthma
BACKGROUND Prebiotics ( commonly oligosaccharides ) added to infant feeds have the potential to prevent sensitisation of infants to dietary allergens .
OBJECTIVES To determine the effect of prebiotic given to infants for the prevention of allergy .
Galacto-oligosaccharides Are Bifidogenic and Safe at Weaning: A Double-blind Randomized Multicenter Study
Objectives : The primary objective of this study was to determine the bifidogenic effect of galacto-oligosaccharides ( GOS ) in a follow-on formula and the effects on other intestinal bacteria . Secondary objectives were the effects on stool characteristics , growth , and general well-being . Participants and Methods : In a multicenter , double-blind study , 159 healthy infants , formula-fed at enrollment ( at 4–6 months ) , were r and omized to an experimental follow-on formula supplemented with 5 g/L ( GOS ) ( 77 infants ) , or to a st and ard follow-on formula ( control , 82 infants ) . Infants were evaluated at enrollment ( study day 1 = sd1 ) , after 6 weeks ( study day 2 = sd2 ) , and after an additional 12 weeks ( study day 3 = sd3 ) . At each study day , a fresh stool sample for the bacterial counts was collected , and the growth parameters were measured . At sd2 , urinary specimens were collected for the evaluation of urinary osmolarity . Results : At sd2 and sd3 , the GOS group had a higher median number ( colony-forming units per gram of stool ) of bifidobacteria than did the control group ( sd2 GOS 9.2 × 109 vs control 4.4 × 109 , P = 0.012 ) ; ( sd3 GOS 7.2 × 109 vs control 2.4 × 109 , P = 0.027 ) . Other bacteria did not show any significant differences between the 2 groups at all study days . The GOS produced softer stools but had no effect on stool frequency . The urinary osmolarity ( mOsm/L ) at sd2 was comparable in both groups . Supplementation had no influence on the incidence of gastrointestinal side effects or on the growth of the infants . Conclusions : These data indicate that the addition of GOS ( 5 g/L ) to a follow-on formula positively influences the bifidobacteria flora and the stool consistency in infants during the supplementation period at weaning . No local or systemic side effects were recorded
No statistically significant subgroup differences were found according to infant risk of allergy or type of infant feed .
