They support SIF 's  efficacy in the management of cow 's milk allergy and infant 's digestive tolerance , as well as its low cross allergy compared to cow 's milk and other formulas .
There is also evidence that demonstrates that SIFs have important advantages in terms of cost-benefit , palatability and effects on the intestinal microbiota , compared to other formulas .
Conclusions Although evidence to recommend its use in functional digestive disorders is limited , SIFs have an adequate safety profile and are still a valid option for infant feeding
Background Soy infant formulas ( SIF ) have long been used as an alternative for infants with special nutritional requirements .
However , the medical indications for their use , their allergenicity , safety and efficacy are still controversial .
Objective To present recommendations for the use of SIF based on the existing literature .
Decreased Regurgitation with a Soy Formula Containing Added Soy Fiber
The objective of this r and omized study was to determine if fiber-supplemented soy formula reduced regurgitation in young infants . We compared regurgitation in 179 infants r and omly assigned cow ’s milk-based ( CM , 90 ) formula or soy formula with fiber ( SF , 89 ) .  Initial daily incidence was similar ( CM , 3.6 ; SF , 3.9 episodes ) , but significantly lower after 7 days on SF ( CM , 3.4 ; SF , 2.3 ; p = 0.001 ) . Less frequent regurgitation after 7 days on SF was sustained after 28 days ( CM , 48 % ; SF , 31 % of feedings ; p = 0.001 ) . Feeding SF effectively managed regurgitation while providing balanced nutrition without altering caloric distribution as occurs with adding rice cereal to formula
