The results showed  that the only time levels of hormone changed in these mice was when they were given [a] massive overdose, containing 1000x more oestrogen than exists in cow’s milk – even pregnant cow’s milk.

There are some good reasons why you might not consume milk (including, but not limited to environmental and ethical reasons), and even some good reasons why some people might not consume it for their health.
