Jeremy Piven says he has stopped drinking soy milk because he started to grow breasts. Usmagazine.com quotes the actor as having said, "I was the guy that dabbled in soy milk, but now I've found out soy milk has enough estrogen for me to grow breasts; I had to put the soy milk down. It was a very confusing time."

ThatsFit.com did some research into the matter after hearing of Piven's claim, and Jill Hamilton-Reeves, assistant professor of family, consumer and nutritional sciences at St. Catherine University in Minnesota determined, "Soy has been studied extensively for 20 years, we haven't found man boobs yet."
