No need to avoid soy - new research

Janet Plant gives a succinct overview of the research on soy and breast cancer in her book "Your Life in Your Hands". She concludes that soy consumption is beneficial.
However, her main recommendation is to eliminate all forms of dairy since these contain harmful growth factors. This argument is contrary to what most hospital dieticians recommend....but having read her book and the evidence that backs it up - references to over 450 research studies - I'm clear about where to put my trust!
