Study Suggests Effects of Products in Soy-Based Formula on Thymus Size
"We have had generations of experience with soy and we have not seen a large population with adverse outcomes," Bakers says. "We haven't seen big swings in particular cancers or reproductive disorders that could be ascribed to a feeding pattern in infancy."
A 1998 statement by the American Academy of Pediatrics on the use of soy-based infant formula says that animal research on the effects of plant-derived estrogens in soy, like genistein, are not conclusive.
"In term infants whose nutritional needs are not being met from maternal breast milk or cow milk-based formulas, isolated soy protein-based formulas are safe and effective alternatives to provide appropriate nutrition for normal growth and development," the Academy says in its statement.
