Soy Milk Is Safe! That Is What the Formula Industry Says
August 25, 2001
Critics suggest that soy formula, because it contains a chemical
similar to the female hormone, estrogen, might disrupt normal hormone
levels and impair development
In a recent study, a 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.
The study relied on the memory of study participants, which may
bias their answers.
Infants fed soy-based formula have long-term
health outcomes similar to those who are fed cow milk-based formula,
the researchers say.
