Allergies and reactions to foods are frequent and may be associated with foods including adapted forms of cow’s milk. Formulas based on protein hydrolysates are used to treat children with an allergy or food intolerance. However, their interest in the prevention of allergy and food intolerance in infants with no manifestation of allergy or intolerance is not clear..

Compare, for infants and children, the effect of the use of hydrolysed formula with that of cow’s milk adapts or breast milk on the occurrence of allergy and food intolerance. If efficiency formulas hydrolysates, determine what type of hydrolysed formula is most effective among partially or extensively hydrolyzed formulas. To determine which infants may have a benefit based on risk vis-?“? -vis the allergy (high or low) and mode of administration of the formula (Early, short or long term).

The standard search strategy of the Group of the Cochrane Neonatal Review was used. The journal has been updated with searches of Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2006), MEDLINE (1966 – March 2006), EMBASE (1980 – March 2006) and CINAHL (1982 – March 2006) and previous reviews including cross references.
