Critics suggest that soy formula, because it contains a chemical similar to the female hormone, estrogen, might disrupt normal hormone levels and impair development. But lead author Dr. Brian L. Strom of the University of Pennsylvania School of Medicine in Philadelphia said the study proves that these are ``unfounded accusations.'' ``(In) a large, long-term study, the products were remarkably safe,'' Strom told Reuters Health. The study, which was funded in part by the International Formula Council, a trade group that represents manufacturers of infant formula, appears in the August 15th issue of The Journal of the American Medical Association (news - web sites). In the study, the team of researchers conducted telephone interviews with 248 men and women aged 20 to 34 years who were fed soy-based formula as infants. Each of the participants answered questions that attempted to assess ``health in young adulthood, with an emphasis on reproductive health.'' The group that consumed soy formula was then compared with 563 similarly aged men and women who consumed cow milk-based formula during infancy and answered the same questions. The only difference between the groups was that women who had been fed soy-based formula reported menstrual bleeding that lasted an average of one third of a day per month longer compared with women in the cow milk-based formula group. But while calling the findings ``reassuring,'' Dr. Frank R. Greer, a professor of pediatric medicine at the University of Wisconsin-Madison, who was not involved in the study, said they were not definitive. For example, the study relied on the memory of study participants, which may bias their answers, Greer said. He suggested that a longer-term study was also needed.
