Milk...does a body bad

"Mongolian physician Ganmaa Davaasambuu has linked increased tumor formation and growth in laboratory animals with chemically induced cancer to high levels of hormones in commercial milk. Seasonal milking practices among Mongolian nomads ensure that cows produce milk only during the first three months of a new pregnancy, when hormone levels are low. Because modern dairies, on the other hand, milk cows well into their next pregnancy, commercial milk often contains much higher levels of biologically active hormones."

Not all bad: Of the milks they tested, "Levels of hormones and growth factors were low in both American skim milk (hormones are carried in the milk fat) and Mongolian milk."  They also found that Mongolian children started growing faster when they drank American milk.

It's a drink for children.

That's from a recent article in Harvard Magazine.
