Can Milk Consumption Trigger Early Puberty? No, Says Chinese Study.
You may have heard the rumor - growth hormones supplied to dairy cows wind up in little Johnny's milk, setting him on a fast track to puberty. Scientific fact or urban legend? A new study from China digs for the truth.
"These findings suggest that breast-feeding or cow's milk consumption does not play a major role in pubertal timing," among children in non-Western countries, the researchers said.
The new study addresses some potential misconceptions held by the public, said Dr. Andrew Bremer, a pediatric endocrinology at Vanderbilt University School of Medicine, who was not involved in the study. "To my knowledge, there's no definitive evidence that exposure to milk causes precious puberty," Bremer said.
