273: Is soy actually good for us? Have we been lied to about soy and phytoestrogens?Today I’m sharing some shocking studies on the health benefits of soy and other foods containing phytoestrogens. Soy may not be for everyone—including me (I share why in this episode)—however, it may actually help several women (and men!) in different ways. Here’s what the science says…

PLUS… foods that contain phytoestrogens beyond soy.

STUDIES:

This PubMed study found that Asian-Americans who ate tofu had a reduced risk of developing breast cancer. The more tofu they ate, the lower their risk.

Here are 11 PubMed studies highlighting how soy benefits our bones:

It appears that just taking a daily pill containing the isoflavone genistein may be enough to reap some of soy's bone density benefits:http://www.ncbi.nlm.nih.gov/pubmed/17577003

People in Asia consume much, much, much more soy than those in the West:http://www.smart-publications.com/cancer/daidzein.php

Interestingly, men may benefit slightly more than women from eating foods rich in phytoestrogens. These compounds are linked to reduced risks of cancer, cardiovascular disease, cerebrovascular disease, and several other conditions:
