REVIEW ER 'S CONCLUSIONS There is no evidence to support feeding with a hydrolysed formula for the prevention of allergy in preference to exclusive breast feeding .
In high risk infants who are unable to be completely breast fed , there is evidence that prolonged feeding with a hydrolysed compared to a cow 's milk formula reduces infant and childhood allergy and infant CMA .
BACKGROUND Allergies and food reactions are common and may be associated with foods including adapted cow 's milk formulas .
Formulas containing hydrolysed proteins have been used to treat infants with allergy or food intolerance , and have been advocated for prevention of allergy and food intolerance in infants .
OBJECTIVES To determine whether use of hydrolysed formulas for infant feeding prevents allergy and food intolerance .
If hydrolysed formulas are effective , to determine what type of hydrolysed formula is most effective including extensively and partially hydrolysed formulas .
To determine which infants benefit including infants at low or high risk of allergy and infants receiving early , short term or prolonged formula feeding .
The natural history of intolerance to soy and extensively hydrolyzed formula in infants with multiple food protein intolerance.
Infants ( n = 18 ) with intolerance to extensively hydrolyzed formulas and soy who responded to an L-amino acid-based elemental formula ( AAF ) were studied until 3 years of age . By 2 years of age most tolerated non-formula foods , and by 3 years only 3 required AAF .  Growth normalized during AAF feeding in 4 infants with failure to thrive
