SOY-BASED FORMULA 30 YEARS LATER

A report in the Journal of the American Medical Association shows that people fed soybean formula as infants are not harmed when they are older.

Soybeans are rich sources of chemicals called phytoestrogens that have many functions similar to the estrogen that a woman's body produces. The estrogen in soybeans has been shown to help prevent cancers of the colon, stomach, prostate, breast and lung. It can also act as a contraceptive in animals. Some doctors are concerned that high doses of female hormones in soybean milk may affect sexual development in both male and female infants. However, this study found no difference between soybean-fed and cow's milk-fed infants in allergies, use of recreational drugs, birth control pills, exercise, breast tenderness, breast size, pregnancy outcomes, education, marriage, diet, height or weight. The only differences were in amounts of menstrual bleeding and menstrual discomfort.
