To be honest I don't have actual data, although such probably exists. But Mils is milk - a product designed for the youngest and most vulnerable individuals. And my logic is, that cow's milk is best for little cows (I can't remember the word), and human milk is best for human babies. So, if we drink milk even as grown up - better it be human milk, after all it was "designed" over thousands of generations to help little humans grow big and strong
