If you've been afraid to eat soy because of the deluge of misinformation about its health effects, relax and enjoy some tofu. Big animal ag is trying to tell you that the phytoestrogen in soy (and in all plants, actually) will stick you full of estrogen and give you breast cancer. It won't. Phytoestrogen isn't estrogen. Meanwhile, these same folks are promoting cow's milk which is the milk of a mother who has recently given birth and thusly is full of actual estrogen. Meanwhile, this study found that soy actually helps protect your body against breast cancer and other cancers. So enjoy!
