However, one of soy’s isoflavones – genistein – is believed to have toxicity issues, though more research is needed as various studies report conflicting results (see Fact Sheet: Phytoestrogen Genistein, from Breast Cancer and Environment Research Centers, or BCERC (1). Genistein is present in other foods, including mothers’ milk, but in much lesser quantities than in soy.
