I've read that non-organic meat and dairy contains Bovine Growth Hormone which doesnt lose it's effectiveness after boilng, pastuerization, etc.
I notice I lost weight when eliminating beef and non organic milk from my diet.
If I have goat's milk or hormone free cows milk or yogurt- I am okay.
Fish is no problem either. It seems its just the stupid growth hormones they insist on giving their livestock that is causing the problems for everyone.
Hormones not only effect you sexually- but they also affect your thyroid and metabolism.
When it comes down to it-- GREED is the underlying cause --because if the entire farming industry was content in normal sized cows or chickens, there would be no insistence on them using growth hormones -- Livestock Growth hormones should be outlawed as far as I'm concerned.
