To Soy or Not To Soy... That is the Question

It seems the more I read about food, the less inclined I am to be waving any sort of banner in anyone's face about what we should or should not be eating.  Why?  As hinted at in previous posts, I am coming around to the notion that what we choose to put in our bodies is a highly personal decision. And that what we eat varies greatly depending on geography, demographics, religious beliefs, nutritional beliefs, and perhaps above all, food availability (or scarcity). 

That being said, I believe that we should educate ourselves with as much information (conflicting though it may seem) so that we can make the best possible decisions for our health and for the well-being of the plants and animals we share the planet with.   It would be great if we could actually trust our food suppliers and believe that what is marketed to us as "healthy" or "good for us" actually is.  Which brings me to the topic of veggie burgers.  They are quite often offered up as a meat-free "healthier" alternative to conventional burgers.  But are they really?
