Also, milk/dairy products in general are chocked-full of cow hormones that cause acne, baldness and prostrate cancer in men. It's best to not consume it.
The first link is a study that found a correlation between skim milk consumption and acne in teenage boys. It by no means conclusively shows causation. Perhaps teenage boys who have a hormone condition which leads to acne also have taste preferences which cause them to enjoy skim milk more, or perhaps skim milk really causes acne to teenage boys. The point is, we don't know.
The second and third links talk about a study for a prostate cancer drug and a human androgen hormone. The word "milk" does not appear on either of those pages.
Please make an effort to be more careful in your citations. When one adopts the tone and form of authority, by citing links to official looking urls, people sometimes take the advice offered without fact checking. And in this case, it could cause people to stop consuming dairy and start consuming something else, with unknown effects.
edit:
The P-Value for skim milk was the only one lower than the .05 significance level. So even in the cited study, there does not appear to be a correlation between whole, 2%, or 1% milk with acne.
Not sure why I'm being down-voted, there have been several major research studies and they all support this. Ask any dermatologist and they will tell you the same thing. Or read some more of the research papers (a dermatologist operates this website):
"The site is a work in progress and will contain the history of the link between milk and acne, links to scientific articles both published and unpublished, thoughts on the mechanisms involved in the production of acne, and treatment protocols I have used with success in managing thousands of acne patients in over thirty years of dermatology consulting practice."
You are drinking lots of pregnant female cow hormones when you drink milk, eat cheese or butter (which is even worse than plain milk as the DHT is already converted). You're just jacking up your DHT levels and that's like turning on an oil spigot. It is a major player in acne and baldness in men.
Not that it's necessary to pile on more here, but just the quote "It's best to not consume it." is an overreaction.
Assuming that the cited articles actually showed causation, it would have to be a pretty significant risk to say not consuming it would be the best choice. It's a cheap and widely available source of protein and fat. Not everyone has readily available access to food, not to mention the cost of preparing and cooking it. It is, however, annoying that the price has gone up by about 22% in the last 10 years. (http://data.bls.gov/cgi-bin/surveymost?ap)
Dairy is not really a cheap source of protein. Most vegetable sources are cheaper - pulses and whole grains.
>It is, however, annoying that the price has gone up by about 22% in the last 10 years.
No, it's really not that annoying. Many of the other foods on that list have undergone similar increases and that 22% hasn't even kept up with inflation. This is also despite the fact that the dairy industry is pretty heavily subsidized. I'm far more annoyed that the price hasn't gone up more to reflect the true cost of dairy.
"We observed a 2-fold higher risk of the serous ovarian cancer subtype among those in the highest category of lactose consumption compared to the lowest
"For each 11-gram increase in lactose consumption (the approximate amount in one glass of milk), we observed a 20% increase in risk of serous cancers
"Women who consumed one or more servings of skim or low-fat milk daily had a 32% higher risk of any ovarian cancer and a 69% higher risk of serous ovarian cancer compared to women consuming 3 or less servings monthly
"Our findings provide some support for the hypothesis that lactose intake increases risk of epithelial ovarian cancer."
"Women who drank two or more glasses of milk per day had relative risks of 1.45 for hip fracture and 1.05 for forearm fracture when compared with women consuming one glass or less per week."
