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 .
Lower Calcium Absorption in Infants Fed Casein Hydrolysate- and Soy Protein-Based Infant Formulas Containing Palm Olein Versus Formulas without Palm Olein
Objective : Quantitative balance studies were performed to compare fat and calcium absorption in healthy , full term infants fed casein hydrolysate-based ( CHF ) and soy protein-based ( SPF ) infant formulas with or without palm olein ( PO ) .  Previous studies have reported that PO significantly reduced absorption of both fat and calcium in cow ’s milk-based formulas in which most of the calcium is inherent in the milk protein . In both SPF and CHF virtually all calcium is added as calcium salts . Methods : Two r and omized , blinded , crossover balance studies were conducted in normal term infants using a three-day home balance method . One study evaluated 10 infants fed commercially available CHF with or without PO , and the other study evaluated 12 infants fed commercially available SPF with or without PO .  Fat and calcium absorption were determined based on the weight of formula intake , weight of stools , and measured calcium and fat in formula and stools . Results : Fat and calcium intake did not differ between the groups fed CHF . However , infant ’s calcium and fat absorption was less , 41 ± 6 % ( Mean ± SEM ) and 92.0 ± 0.8 % , respectively , when fed CHF with PO compared to 66 ± 5 % and 96.6 ± 1.1 % , respectively , when fed CHF without PO , ( p < 0.01 ) . For infants fed SPF , fat and calcium intake did not differ between the feeding groups . Mean calcium absorption was also significantly less when infants were fed SPF with PO , 22 ± 3 % , than when fed SPF with no PO , 37 ± 4 % ( p < 0.05 ) . Fat absorption did not differ between the two SPFs . Conclusion : This study demonstrates that PO , as the predominant fat , is associated with significantly lower absorption of calcium from infant formulas in which calcium salts are the source of calcium . These findings corroborate previous reports of this negative effect of PO in cow milk-based infant formulas in which most of the calcium is a component of the cow milk protein source
