Milk in Mongolia is only gotten from cows five months out of the year, when estrogen is low.
If a cow is pregnant, milk is only collected early in pregnancy, when estrogen is lower.
These practices avoid the times when a potent growth-promoting estrogen (estrogen sulfate) is as much as 33 times higher in milk.
In the USA, mass production of dairy, including organic dairy, doesn't allow for this kind of reduced schedule.
Estrogen in dairy accounts for 60 to 80 percent of estrogen consumed in the United States.
Natural estrogens, like what is found in cow's milk are as much as 100,000 times more potent than their environmental counterparts, such as the estrogen-like compounds in plastics in their effects on the growth of cancers.
That's one of the main reasons that cancer rates in countries, like the USA, that consume a lot of dairy products are higher than countries that don't consumer much dairy.
The other two main reasons are that dairy stimulates production of Insulin-Like Growth Factor 1 (IGF-1) and insulin, two potent growth factors that can promote cancer growth.
