Hi. There is some debate about toxins in soya. There are those who say soya is healthy, and those who say it is not because the way it is mass-produced doesn't allow a long enough fermentation process. Also, that in the traditional countries that use soy, they wouldn't use it in the quantities in western countries. I have a little soya - like soy based sausages a couple of times a week - but I now try to limit the amount of soy I have just to be on the safe side. They also have estrogenic properties, and mercury toxic women often have estrogen dominance already.
