Sound, credible research is all over that dairy products are dangerous for our bodies. Yet, we see and hear everywhere “3-a-day.” The clencher is that the dairy industry funds that advertising. Thus, 3-a-day of dairy is not on every billboard in hopes of improving your health, but in hopes of making a few more bucks. Take time to do your research; it is important as it will influence the very quality of you and your family’s lives.
Here are a few of my favorite points from an article published by the Harvard University Gazette. The entire article can be reached through this link.
Hormones in milk can be dangerous

Ganmaa’s topic was lunch-appropriate: the suspected role of cow’s milk, cheese, and other dairy products in hormone-dependent cancers. (Those include cancers of the testes, prostate, and breast.)
“Among the routes of human exposure to estrogens, we are mostly concerned about cow’s milk, which contains considerable amounts of female sex hormones,” Ganmaa told her audience. Dairy, she added, accounts for 60 percent to 80 percent of estrogens consumed.
Milk from a cow in the late stage of pregnancy contains up to 33 times as much of a signature estrogen compound (estrone sulfate) than milk from a non-pregnant cow.
In a study of modern milk in Japan, Ganmaa found that it contained 10 times more progesterone, another hormone, than raw milk from Mongolia.
In traditional herding societies like Mongolia, cows are milked for human consumption only five months a year, said Ganmaa, and, if pregnant, only in the early stages. Consequently, levels of hormones in the milk are much lower.
“The milk we drink today is quite unlike the milk our ancestors were drinking” without apparent harm for 2,000 years, she said. “The milk we drink today may not be nature’s perfect food.”
Cancer rates linked to dairy can change quickly, said Ganmaa. In the past 50 years in Japan, she said, rising rates of dairy consumption are linked with rising death rates from prostate cancer – from near zero per 100,000 five decades ago to 7 per 100,000 today.
Butter, meat, eggs, milk, and cheese are implicated in higher rates of hormone-dependent cancers in general, she said. Breast cancer has been linked particularly to consumption of milk and cheese.
In another study, rats fed milk show a higher incidence of cancer and develop a higher number of tumors than those who drank water, said Ganmaa.”
“But steps can be taken now to reduce the amount of hormones in milk, said Ganmaa. Because hormones reside in milk fat, drinking skim milk is one option. Getting calcium from green leafy vegetables is another.”
