Dear Lactnetters No answer to my question about anticanceral properties of genistein and daidzein found in human milk after maternal consumption of soy. Are they phytoestrogens ? Something other ? I am sure someone has ideas. References of the study (I have only an abstract) : Franke et al. Daidzein and genistein concentrations in human milk after soy consumption. Clin Chem 1996 ; 42(6) : 955-64. Thank you. Kind regards Françoise Railhet LLL France Medical Associates Program
