Soy?! BAD for health?!

I guess the word Soy and unhealthly never came together in my mind before until my friend sent me this email about a girl getting all sorts of illnesses after consuming soy products like a drug addict... so i went to do a little research on soy and boy did i find out alot on the bads of soy ... for example it mimics some hormones in the female body and increases risk of booby cancer and it affects the thyriod glands and for men it affects metabolism rate making it difficult to lose weight!!! I'm not sure whether its really really as in REALLY true or not but it has definitely put me off soy... wonder if any of my dear friends(ESPECIALLY those who studied Food and Nutrition) can enlighten me a lil bout soy, as in whether is it really harmful... For the good of health!!! TATA!!!
