Myths about cow’s milk busted

Concerns that oestrogen levels in cow’s milk have an effect on blood levels and reproductive hormones in humans have been found to be just that, concerns and not a fact! In order to gain a better understanding of the link between oestrogen in milk and blood oestrogen levels, a team of researchers from the University of Ljubljana in Slovenia looked at the effects that different levels of milk oestrogen had in adult mice. “The aim of our study was to evaluate whether the consumption of milk with known doses of oestrogen could affect blood hormone levels and reproductive organs in mice”, explained senior co-author Tomaz Snoj, DVM, PhD, Veterinary Faculty at the Institute of Preclinical Sciences, University of Ljubljana, Ljubljana, Slovenia.

“Our results suggest that oestrogen in milk, even when derived from cows in the third trimester of pregnancy, do not pose a risk to reproductive health”, concluded Dr Majdic. “Even oestrogen at concentrations 100 times higher than usually found in native milk did not cause any physiological effects in the present study.” This is indicative that naturally occurring hormones in milk are found in far too low concentrations to have any biological effect on consumers.
