Cancer Soy Controversy
Transcription from Lecture, Fight Cancer with your Fork:
“To soy or not to soy, that is the question. If we had three more weeks, we could probably get to the bottom of it. I’m gonna go over it in 30 seconds. Soybeans contain weak plant sources of estrogen called phytoestrogens and what they do is they compete with and crowd out the more dangerous type of estrogen that promotes breast cancer. They actually hop onto the receptor sites and don’t give the other ones a chance to get on.
The key class of chemicals in the soybeans is Isoflavones and one particular Isoflavone is called genestein and that’s an angiogenesis inhibitor. Angiogenesis the process by which a cancer tumor develops its own blood supply to feed it the sugar and fat we keep sending its way. We don’t want angiogenesis, so the genestein in the soybeans can help inhibit that process.
There’s a ton of controversy about soy. Some doctors will restrict their patients from consuming all soy products because of those weak plant estrogens. However, most of the controversy about the soy seems to exist because the form and the quality of the soy have never been defined in the research studies. Most western forms of soy are of little value or possibly harmful but Asian soy is highly fermented and therefore very valuable.
So if you’re getting soy, make sure that it’s organic, non GMO, that it’s loaded with enzymes through fermenting or sprouting, and it must be minimally processed. One of my favorite forms of soy is miso, which is a fermented soybean paste that we get from Asia.”
