View Full Version : Soy protein (and products) good or bad?

I am questioning very much if soy protein and soy products are things that I want to ingest.

After reading articles on T-nation and a few other web sites, I'm leaning towards NOT taking in products that are primarily (or major percentage thereof) made with soybeans. The only soy product that seems safe is soy sauce because it is fermented. The fermentation process seems to remove the toxins and other bad properties of soy.

Information on this can be found here:

What do you think?

Yep, fermented is fine. This means natto and miso are safe, too.

I'm quite fond of miso. Natto scares me though. Maybe Maki has a word to say about this sticky stuff...

natto and miso? Don't know what that is. Elaborate?

I'm kinda bummed that soy sources seem to be not so good for people. I started using organic soy milk about 7+ months ago thinking that it was better than the regular cheap cow's milk. Also liked that it came in the vanilla flavor. It cost a little more, but thought I was doing myself a favor—guess not. Organic cow's milk is soooo expensive. I don't want to buy it at $8.00 a gallon versus $3.00 to $3.25 a gallon for the non-organic cow's milk. The processed non-organic cow milk probably isn't all that good for a person either.

Eating/drinking clean food can sure be expensive.

There is another thread on this very subject right now.

I didn't see that other thread, sorry. Also, it seems targeted to the problem of estrogen (which is a problem for men). While estrogen is a concern, I'm also wondering about the toxins and other problems of soy products.

[following excerpts quoted from this page (http://www.soyonlineservice.co.nz/03toxins.htm)]

Protease Inhibitors
...inhibit the action of proteases (including trypsin) which are enzymes that are involved in the process of dismantling proteins for use by the body. ... (the page also hints at the idea that the inhibitors might contribute to cancer).

Phytates
... Soybeans contain very high levels of phytate and their are numerous reports of reduced bioavailablity of various metals from foods containing soy ... (seems to reduce the amount of needed metals in food by binding to metal ions such as calcium, copper, iron, manganese and zinc)

There is more to read on that page that may or may not apply to everyone.

Don't apologize, I wanted to make sure you saw it, as it might apply to your questions.

Thanks for letting me know. Here is a short news video (http://webserve.kml.co.nz/soyonlineservice/downloads/Soy_&_Cancer_Prime_TV_14Jan07.wmv) if anyone is interested in seeing it.
