The natural disappearance of the milk-digesting enzyme lactase from the human system upon reaching maturity proves that adult humans have no more nutritional need for milk than adult tigers or chimpanzees.
Today, milk is made even more indigestible by the universal practice of pasteurization, which destroys its natural enzymes and alters its delicate proteins.

The argument against milk often heard is that humans are the only animals that drink it after infancy. That is because we are the only ones to have domesticated other animals. However other animals will drink it regularly if they retain the lactase gene, and milk is offered to them - think of domestic cats. In the case of humans, those populations who have not had domesticated sources of milk have lost the lactase gene, so they get the abdominal upset from milk products, and those who did have domesticated sources of milk have kept the enzyme and are able to digest milk products without problem (look up lactase deficiency in PubMed -
http://www.ncbi.nlm.nih.gov/pmc/arti...tool=pmcentrez is one article on point).
It is hard to isolate the elements of a diet that contribute to health. Dairy products are a part of the DASH diet and the Mediterranean diet. They include foods that are high in calcium and potassium, which contribute to lower blood pressure and denser bones, and those populations consuming those diets have increased longevity and lower cardiovascular disease. And milk has a highly desirable ratio of protein to carbohydrate.
I am unaware of any rigorous studies showing detrimental effects of pasteurization. One positive is that it does prevent scrofula, which I developed from unpasterized milk as a child. If you can be sure that your source of unpasteurized milk does not carry the tubercle bacillus, you can be safe from scrofula.
