What Do You Make of the Hormone Content of Dairy Products?

This study goes into it in pretty good detail: http://www.journalofdairyscience.org/article/S0022-0302%2810%2900256-0/fulltext

The conclusions that the researchers draw at the end regarding how small an increase in serum estrogens there is for, say, a woman drinking a glass of milk, are likely sound. I wonder though about a male (or even female) eating a high butter diet, such as the sort we see around these parts.

I don't really remember my voice getting higher (though my LDL certainly did) during my great butter misadventure, but it was enough of a quantity that I suspect that it would have made a difference hormonally. If I had eaten in that way for long enough, assuming that the LDL didn't become oxidized and lead to a heart attack, I don't think it's out of the realm of possibility that my prostate cancer risk would have been elevated. These fellows hypothesize that there is a link: http://www.sciencedirect.com/science/article/pii/S0306987703002950

This is the main reason I shy away from dairy products as a daily item- major exogenous estrogen load probably leads to some form of endocrine disruption.

Damn it. I like dairy products! Sometimes I think ignorance really is bliss.

Can you post a link that supports the idea that traditional cultures don't milk pregnant cows?

Yeah, that seems to be a large part of the problem and the reason why we can't compare this to milk consumed by the Maasai or early Europeans.

It would help if we were not drinking the milk from pregnant cows.

I personally think that the hormones in conventional milk can be a problem and can disrupt your own hormone production. I definitely think that most dairy should be avoided, especially for women dealing with PCOS or fertility issues.

This presentation by Pedro Bastos at the 1st Ancestral Health Symposium is very enlightning.

"Dairy, Hormones, and Human Health" by Pedro Bastos, MA, MS

Pastured milk may be slightly better, but more data is needed to be sure.

Anyone who claims the hormones in milk do anything negative doesn't understand hormones period. Most of these retards only mention the estrogen but don't mention the progesterone which is much higher in pregnant milk, the progesterone would negate any effect the estrogen has. Let's not even get into how small of an amount dairy products actually contain of these hormones. It's all just fear monger scare tactics, probably from seed milk manufacturers

Wikipedia on the Medical Hypotheses journal:

"The journal's lack of peer review[4] and publication of ideas that are considered clear pseudoscience,[5] particularly AIDS denialism,[6] attracted considerable criticism, including calls to remove it from PubMed, the prestigious United States National Library of Medicine online journal database."


So I'd be a bit skeptical about that paper.

(later edit)

I just checked with a dairy farming acquaintance, who replied: "in NZ, cows are dried off at the end of the season and don't get milked again until post-calving." So here in New Zealand, at least, I'm not going to worry about my modest intake.
