Study: Infants don't need 'special' formula

June 23, 2009 The study, published online in The Nutrition Journal, compares infants' tolerance to standard formula and so-called hypoallergenic formulas.

The special formulas contain cow's milk proteins, like the others, but the difference is that the proteins are broken down making them less likely to trigger digestion trouble or allergic reactions.

But a study of more then 300 infants using both kinds of formula finds both groups had similar rates of intolerance, between 12 and 14 percent.
