Fermented formula has the potential to reduce some , albeit not well-defined , digestive symptoms .
Current evidence does not support the use of fermented formula for preventing cow ’s milk allergy .
Conclusion : Limited available evidence suggests that the use of fermented infant formula , compared with the use of st and ard infant formula , does not offer clear additional benefits , although some benefit on gastrointestinal symptoms can not be excluded .

Abstract Fermented formulas , i.e. , those fermented with lactic acid-producing bacteria during the production process and not containing significant amounts of viable bacteria in the final product , are widely available in many countries .
Our aim was to systematic ally review published evidence related to the safety and health effects of the administration of fermented infant formulas compared with st and ard infant formulas .
[Intake of fermented milk containing Lactobacillus casei DN-114 001 and its effect on gut flora].
OBJECTIVE To study the gut flora in infants who received fermented milk containing Lactobacillus casei and Streptococcus termophilus  and its effect on secretory immunoglobulin levels . MATERIAL AND METHODS An experimental , r and omized , prospect i ve , parallel group study was carried out . Thirty-five infants were included ( 18 in the treatment group and 17 in the control group ) with a mean age of 2 years ( SD : 0.6 years ; range : 1 - 3 years ) . The experimental group received both fermented milk ( 0.5 l/day ) containing L. casei and S. termophilus for 6 weeks and st and ard cow 's milk for the following 6 weeks . The control group received st and ard cow 's milk ( 0.5 l/day ) for 12 weeks . Secretory IgA levels in saliva were evaluated in the experimental group at the start of the study ( baseline levels ) and 6 weeks later . In both groups , stools were collected to study gut flora at 0 , 6 and 12 week . RESULTS Secretory IgA levels significantly increased ( p = 0.0063 ) from a mean baseline value of 2.5 mg/dl to a mean of 3.4 mg/dl at 6 weeks . Gram-negative aerobic flora were decreased in the experimental group after 6 weeks compared with the control group ( p = 0.0203 ) . The number of infants with Lactobacillus spp in their gut flora was greater in the experimental group than in the control group at week 6 and this difference was statistically significant ( p = 0.028 ) at week 12 . Conclusion The present study provides evidence of L. casei survival in the gastrointestinal tract and of its effect of increasing secretory
