But it certainly seems that there is a lot more going on behind the scenes when it comes to the truth about soy formulas. What has finally been revealed is quite shocking.
Something very troubling began to be noticed in Puerto Rico twenty years ago. In 1982 pediatric endocrinologists reported on an increase in the incidence of breast development in girls as young as two years old. In one study approximately 65 percent of the cases (85 out of 130) studied experienced the onset of sexual development before they were 18 months old.
Many causes were investigated and eventually the real culprit was found. Soy-based infant formulas! It was discovered that the phytestrogens in soy formulas were stimulating this early development.
A 1997 Lancet study showed that soy has glycosides of genistein and daidzein or plant-based chemicals that mimic estrogen. They display a wide range of hormonal and non-hormonal activities. The daily exposure of infants who consume soy formulas was six to eleven times higher than adults who are consuming soy foods. The blood concentration of these hormones was 13,000 to 22,000 times higher than estrogen in the blood. The authors of this article speculate that this concentration may be sufficient to exert biological effects, whereas the contribution from breast-milk or cow-milk is negligible.
