This is all the same bogus information by the Weston Price Foundation that has been debunked so many times. They have an agenda to bash soy since soy is the biggest competitor of their largest financial supporters, the beef and dairy industries.
For example, this statement: "New data indicate that environmental estrogens such as PCBs and DDE (a breakdown product of DDT) may cause early sexual| development in girls". This has absolutely nothing to do with soy other than the fact that soy will protect the body from the dangerous effects of PCBs and DDT. Soy also protects people from the strong estrogens found in meats and dairy that are the real link between foods and early sexua| development of children.
