Male Speaker: You've mentioned soy formulas. Are there any advantages and disadvantages of using a Soy formula? Martin D. Fried: The main advantage of using soy formula is it might be the first formula you would switch if somebody had a milk protein, cow milk protein allergy. Or even a mother who is breast feeding and is taking milk products and the cow milk is passing into the baby and the baby is allergic to it, but 30% of all children who are allergic to cow's milk or allergic to soy. Male Speaker: So what would be the disadvantage of using a soy formula? Martin D. Fried: The disadvantage would be that they could still be allergic to what they could get a colitis, blood and... Male Speaker: A reasonable substitute but you shouldn't go to it as a good justification? Martin D. Fried: Right. Male Speaker: Okay, if the soy formula, is there anything that sort of matches breast milk or varies with breast milk or in terms with consistency? Martin D. Fried: Well soya is a different protein than whey and casein. It does curdle as much as far as its emptying properties go, it's, the casein has the slowest time because it curdles, soya will be the next slowest and then whey would be the fastest.
