Molecular effects of genistein on estrogen receptor mediated pathways - PubMed

Genistein, a component of soy products, may play a role in the prevention of breast and prostate cancer. However, little is known about the molecular mechanisms involved. In the present study, we examined the effects of genistein on the estrogen receptor positive human breast cancer cell line...

Main takeaways from this study, “We also found that genistein, though estrogenic, can interfere with the effects of estradiol. In addition, prolonged exposure to genistein resulted in a decrease in estrogen receptor mRNA level as well as a decreased response to stimulation by estradiol.”
genistein (soy phytoestrogen) decreases estradiol, a much more potent estrogen

Estrogenic effect of yam ingestion in healthy postmenopausal women - PubMed

Although the exact mechanism is not clear, replacing two thirds of staple food with yam for 30 days improves the status of sex hormones, lipids, and antioxidants. These effects might reduce the risk of breast cancer and cardiovascular diseases in postmenopausal women.

pubmed.ncbi.nlm.nih.gov

Main takeaways: diosgenine (sweet potato/yam phytoestrogen) “increases in serum concentrations of estrone (26%), sex hormone binding globulin (SHBG) (9.5%), and near significant increase in estradiol (27%)”
Some phytoestrogens are expectedly bad, increasing strong estrogens.

Summary: soy surprisingly decreases stronger estrogens, yams seem to be far more estrogenic plants.

admittedly the soy study is in vitro, but what are your thoughts on soy after reading this? Anecdotally many people feel soy does the opposite, so i would like to know what you guys think
