Guest guest Report post Posted March 17, 2010 It's a matter of personal choice, and I choose to avoid soy whenever I can. Putting " soy toxins " into Google is eye-opening. It is certainly controversial, with the massive soy industry touting soy as manna from heaven and others suggesting it is straight from hell.

If you buy packaged/canned foods you pretty much cannot avoid soy completely, as it is in so many products; often without being listed of the label. TVP is made from soy, for example. IMHO the soy industry has taken a waste product always considered unfit for human consumption that contains numerous toxins and has converted it to a " health food " . While some of the toxins can be removed not all of them are. IMHO it was one of the most successful propaganda/advertisement campaigns of all time. Regards, .. .. > > Posted by: " pilarave2@...

Among other things, soy carries metals into your body. Barbara Lochner Quote Share this post Link to post Share on other sites
