Got Milk?

Most of us in the US grew up drinking milk, unless your mom figured out you were lactose intolerant from some allergic reaction.  Milk, in its raw, organic, unpasteurized, nonhomogenized state from grass-fed cows are full of nutrients and fat that we need to stay healthy.  However, what is typically sold in the grocery store is nothing close.  This is what I want to talk about.

Conventional milk typically has tons of antibiotics, steroids and hormones because of the way they "factory" the cows by putting them in areas, where they almost touch, stand still, row after row, many times in the dark, and milk the cows on unnatural schedules in order to maximize the milk production.  This maximization causes the dairy cows' udders to become very painful, heavy and infected.  In response, producers have to put these poor animals on more drugs to lessen the pain, reduce disease, and keep that milk production going around the clock.

This terrible cycle causes large doses of antibiotics and hormones in the milk and meat.  On top of that, they typically pasteurize and homogenize.  Both procedures destroy vitally important health-giving compounds in the milk, destroying enzymes, vitamins, vitamins B12 and B6, and promote pathogens.  However, unpasteurized milk may harbor harmful bacteria (thanks friends for point this out!), as the FDA states, so certain processes may be necessary. 

There also has been talk about a link between milk and cancer, including ovarian cancer.  According to research published in November 2004 in the American Journal of Clinical Nutrition, some Swedish researchers concluded that "our data indicate that high intakes of lactose and dairy products, particularly milk, are associated with an increased risk of serious ovarian cancer, but not of other subtypes of ovarian cancer."  Although we really don't know what kind of milk they were drinking or have multiple, multiple studies, but it should cause us to think about it (especially for those who drink conventional milk with cereal for like every meal--I was one of those in college).

The other thing to really question is why kids hit puberty SO MUCH earlier than people 50+ years ago.  Girls are wearing their first bra at younger ages.  My theory, and personal opinion, is that this abnormality could be very seriously linked to the impact of all the hormones and antibiotics industry uses.  Kids are fed milk from a very young age.  I am sure multiple factors, but this might be one (and potentially big one).

It is vital to know where your food is coming from.  I do drink milk every day for the most part, although I have learned that I can get calcium from many other foods such as kale and other vegetables.  Remember cheese also comes from the cow, so this same practice also impacts the nutritional value of it (to learn more: Is That Really Cheese?).  I drink Organic Valley milk.  From my research, Organic Valley is a co-op of farmers who really care about pasturing their cows and don't use hormones.  In addition, I have switched to whole milk; I was fat free for years.  Since my diet has changed, I now use milk to get some of my saturated fat.

I was actually just talking to my brother's fiancee about milk last night (she's a veterinarian) - she was saying that unpasteurized milk can be pretty dangerous, because many infections, diseases, etc. that the cow has will be passed along in the milk and have the potential to cause serious problems in humans. Her take was that if you were going to drink raw milk, you should make sure that you know both the farmer and the cow personally and can make sure that the animal is completely healthy - it's not worth the risk otherwise.

But I'm totally in agreement with you about the issues with factory farming cows - the amount of antibiotics we give them is ridiculous, and it's a major contributor to the rise of antibiotic resistant forms of bacteria (if I remember correctly, antibiotic use in agribusiness is far, far higher than its use in hospitals or households). And while I suspect that early puberty is more linked to the artificial hormones that are pervasive in our environment at large (food can linings, plastics, baby bottles, receipt paper, etc. - BPA is more prevalent and more dangerous) rather than primarily localized to dairy, I agree that rBGH is a problem.

On the plus side, organic milk is actually supposed to have more nutrients.

Dawn! Thanks for the great comments. I agree with your commentary, actually I think the milk topic could take multiple posts at the very least, since it has many sides to discuss.

Unpasteurized milk is not available in grocery stores for the reason you give, which is why Organic Valley is pasteurized.

On other artificial hormones in the environment, sure, I agree, and it is pretty hard to measure the exposure people have versus the impact it has on the body. I just think for those who grow up in the US, kids consume quite a bit of milk and cheese (milk in school, pizza, etc.), and kids' puberty is earlier than many non GMO countries (anecdotally speaking at least). I am sure other factors are involved as you mentioned, but just think hormones in animals is something we all need to think about...

Thanks for the comments!

Interesting post! Here's a great article from the FDA about the importance of pasteurization. http://www.fda.gov/Food/ResourcesForYou/consumers/ucm079516.htm
At least in medical school, we learn that pasteurization has had a huge impact on infectious diseases. And it's very dangerous to drink raw milk.

In regards to girls reaching puberty earlier, some part of this is the childhood obesity epidemic. Fat secretes estrogen and other hormones.. which can contribute to earlier puberty.

Hi Jeanie! Thanks for the article, I will add it into my post as a source, thanks!
