A researcher from Harvard University has discovered that there is a tremendous difference between raw, natural milk and the p asteurized milk from factory-farmed cows that is found in most groceries and supermarkets.
The researcher and her team found that pasteurized factory-farmed milk contains dangerously high levels of the hormone estrogen that has been linked to cancers of the testes, prostate, ovaries, uterus and breast.
Ganmaa Davaasambuu, M.D., Ph.D. and colleagues identified “milk from modern dairy farms” as being dangerous. Cows there are milked 300 days/year, including while they are pregnant and soon after giving birth. In her native Mongolia cows are still milked traditionally – not milked until six months after giving birth and not while 3 or more months pregnant.
Pasteurized factory milk was found to contain up to 33 times more estrogen than traditionally milked cows.
“The milk we drink today is quite unlike the milk our ancestors were drinking,” Dr. Davaasambuu said in the Harvard University Gazette. “When [cows] get pregnant, the estrogen levels in their blood, milk, and urine increase.. This made me wonder – since the cows are pregnant all the time, the hormone levels in their milk should be really high.” (6)
In contrast, raw milk from grass-fed cows milked at the proper times is linked to improving digestion, healing autoimmune disorders and boosting overall immunity, which can help prevent cancer.
