(TNS) – Texas University medical scientists have released a study that links breast tissue size to the growth hormones used in animal feed. “We are on the road to having conclusive proof” said Tim Watkins, a scientist in the TU Dermametrics lab, “that links animal growth hormone usage to an average size increase in female breast sizes seen in the last two decades.” The study, which was released Tuesday, followed the dietary patterns of 1,524 women from age 10 to 16 for 6 years. Half of the test subjects ate what would be considered a normal average diet for American women and half ate organic food products only. The normal diet survey group had no restrictions on the type of meats consumed and randomly had the meat tested for growth hormones which were found present more than 85% of the time.
