Do partially hydrolyzed infant formulas prevent allergies in high risk infants?
Research from Murdoch Children's Research Institute in Melbourne has found that partially hydrolyzed whey infant formula (PHF) is no better at preventing the development of allergies in high risk infants than regular cows milk infant formula or soy formula. PHF is usually recommended for non breast fed infants with a family history of allergy.
The study enrolled 620 infants at high risk of allergies before birth and allocated them to receive either PHF, regular cows milk infant formula or soy infant formula when breastfeeding was discontinued. Allergic reactions to egg, milk, peanut, dust mite, rye grass and cat dander by skin prict test was measured at 6,12 and 24 months. Children were monitored up to age 7 years.
The study found no decreased risk of allergies in those children given the PHF compared to those given the regular cows milk or soy milk formula. The PHA formula made no difference to the development of hay fever, asthma or eczema although there was no increased risk of allergies in those using the PHF. For those families at high risk of allergies breast feeding is the preferred method of feeding.
