For men over 45, there is a correlation between milk and BPH (enlarged prostate and difficulty in urination). Farmers inject hormones (and other things), and the animal produces its own. All of these excrete into the milk causing irritation to the prostate and the resulting enlargement causes difficulty in urination. Same problem with whey protein powders and cheese. BUT! If the item is cooked, then there does not seem to be an effect. [1]
