[EMAIL PROTECTED] wrote: It is a growth hormone. The hormone increases milk production in cows. Some studies, however, indicate it may enter the bloodstream when people drink the milk and cause increased incidence of certain types of cancer. Some studies also indicate that it may cause health problems in the cows as well. BST has not been proven harmful. THe problem is that studies that show that it may be harmful have been overlooked or even suppressed as the documents show. More studies need to be done before we can be sure it is safe. As noted, you may already have BST in your bloodstream. Maybe you should go back to Poland, or come to Canada.
