Cows are kept pregnant all year round. They give birth and within six weeks they are forcibly impregnated again. As a result of this almost constant pregnancy, their sex hormones including oestrogen are sky high. These hormones go into the milk, their maternal milk, and therefore the dairy products we consume are laden with sex hormones. Cows milk is specifically designed with enough fat and protein to make a baby calf reach adulthood in 18 months. No wonder we are seeing our children reaching puberty at younger and younger ages.
