AUTHORS ' CONCLUSIONS Feeding with a soy formula can not be recommended for prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance .
BACKGROUND Allergies and food reactions in infants and children are common and may be associated with a variety of foods including adapted cow 's milk formula .
Soy based formulas have been used to treat infants with allergy or food intolerance .
However , it is unclear whether they can help prevent allergy and food intolerance in infants without clinical evidence of allergy or food intolerance .
OBJECTIVES To determine the effect of feeding adapted soy formula compared to human milk , cow 's milk formula or a hydrolysed protein formula on preventing allergy or food intolerance in infants without clinical evidence of allergy or food intolerance .
Growth and protein status of term infants fed soy protein formulas differing in protein content.
OBJECTIVE The purpose of this study was to compare growth and protein status of healthy term infants from 2 to 112 days of age fed a commercially available soy-based formula ( IS ) and a similar formula ( EF )  containing less protein ( 2.91 vs 2.45 g/100 kcal ) . DESIGN A controlled , r and omized , blind parallel clinical trial was conducted in 32 male and 32 female infants . Infants were enrolled at 2 days of age , and their assigned formula was their only feeding to 112 days of age . At this time their weight , length , and head circumference were measured . Weight , length , and head circumference were measured and formula intake , formula intolerance and stool characteristics were recorded at 8 , 28 , 56 , and 112 days of age . Plasma urea nitrogen ( PUN ) , total protein , albumin , and transthyretin were determined at 56 and 112 days . RESULTS There were no statistically significant differences in weight , length , head circumference , or gains in these measures . PUN concentration was significantly lower in infants fed EF than IS at 56 and 112 days . Plasma total protein , albumin , and transthyretin concentrations were not different between the two feeding groups at the two testing periods . Tolerance to the two formulas was similar . Stool characteristics did not differ between the two groups . CONCLUSION A soy-based formula containing 2.45 g protein/100 kcal and approximately 640 mumol of total sulfur containing amino acids/100 kcal adequately meets the protein needs of term infants from 2 to 112 days of age
