Researchers in the American Journal of Clinical Nutrition also found significant cell proliferation in breast tissue from soy supplementation in only 14 days. And a Japanese study at the Ishizuki Clinic found that just 35mg of isoflavones per day caused thyroid suppression in healthy individuals in just three months.
Sadly, most of the positive information we hear about soy is from companies marketing soy, or the governments controlled by them. It should never be treated as a meat or milk replacement, and selling it as an infant formula should be illegal.
In 1992, the Swiss Health Service estimated that two cups of soy milk per day provides the estrogenic equivalent of one birth control pill… and infants fed soy formula the equivalent of five birth control pills.
