Milk Isn’t Nearly As Good For You As You Think

“Thank you, pretty cow, that made / Pleasant milk to soak my bread.” —Anne Taylor, “The Cow”

In A Nutshell

We’ve always been told that drinking a lot of milk is crucial to developing strong bones and keeping conditions like osteoporosis at bay. While we do know that calcium is an important part of maintaining bone health and strength, it’s been found that milk and other dairy products aren’t necessarily the best ways to do it. In fact, too much milk has been tied to an increased risk of some types of cancers.

The Whole Bushel

We’ve been hearing it ever since we were kids: from our parents, from television commercials, from advertisements. Drink lots of milk and you’ll stay healthy, have strong bones, and keep health complications at bay down the road. But once institutions started revisiting the question of just how healthy milk is for us, they’ve found that the answer might be a little disturbing for those who swear by their morning glass of milk.

First, the good news. Calcium is absolutely necessary for a healthy body overall, and milk does contain a lot of calcium.

That’s about all there is for good news for milk lovers, though.

Milk also contains other things that aren’t so good for us, especially whole milks. Whole milk—and other dairy products—can be high in saturated fats; this isn’t just bad for maintaining a healthy weight, it can also be bad for bone structure, too.

The Harvard School of Public Health has been looking into the matter of just how effective milk is at keeping conditions like osteoporosis at bay. And they’ve found that there’s no real evidence of any positive correlation between the amount of dairy and milk a person consumes and how likely they are to prevent the development of osteoporosis. The study has been looking at 25 years’ worth of comprehensive data.

According to another study that looked at 72,000 women and how often they drank milk, those that drank two glasses a day were more likely to have suffered broken bones than those who drank it only occasionally.

There are also a few disturbing studies that have found a correlation between drinking milk and something else, however—cancer. A study published in the Journal of the National Cancer Institute found a correlation between a higher chance of surviving breast cancer found among women who don’t drink a lot of milk. The study wasn’t directly targeting milk, but the fats that are present in it. Other types of saturated fats had little to no effect on mortality rates, but only dairy fats showed any direct impact.

There have also been a number of studies linking milk consumption with the prevalence of prostate cancer. Men who drink less milk are statistically at a lower risk for developing prostate cancer and, similarly to the breast cancer studies, those that drink less milk have a higher chance of surviving. Similar to studies that have been performed with groups of women, it’s also been found that men’s milk consumption has little to do with the development of osteoporosis.

Those who stay away from milk and find their calcium elsewhere have also been found to statistically have lower cholesterol as well.

When looking at countries overall, those that are high on the scale of cow’s milk consumption also suffer the most instances of bone fractures.

So where should you be getting your calcium and other vitamins?

There are many green vegetables—like collard greens, broccoli and bok choy—that are high in calcium. The added benefits of turning to vegetables for calcium is that they’re usually also rich in other important vitamins, like D and K, and don’t have the high fat content that milk can have.

    Good to read when drinking a glass of milk!

    There is an alternative viewpoint for everything that we eat/drink. Damned if you do, damned if you don’t.

    Milk it does a body…no good? Well not really being a big milk drinker I’m not going to worry about it. Now if some great scientist could discover how beer can help you live a super healthy life that would be something.

    • percynjpn

      That’s interesting, because I’ve read studies that say beer actually helps strengthen bones.

        My bones must be like iron then.

    Is Debra Kelly the daughter of Morris M? I’m going to go buy a gallon of whole milk right now.

  • bowo

    The adverse effects mostly come from saturated fat content in milk. What about skimmed or low fat milk?
    Some vegetables indeed contain calcium but nowhere as much as dairy, you have to eat a shitload to fulfill your 1000mg/day RDI.

    I think that Milk is very good for strong Bone and make a good health .

    If you are in North Carolina, and possibly other US states, it doesn’t matter if you want healthy milk. Buying milk directly from a farmer, for human consumption, is illegal. It must be FDA approved. Which means bad for you. They remove the good stuff, put in artificial good stuff that is actually bad for you, and the cows are eating corn chock full of GMOs. Which means the milk is full of that crap too. I don’t even care much about this kind of thing, and even I think this is completely and utterly retarded for the state to do. Basically, you can’t legally buy the stuff that is actually good for you because the country can’t tax it, and can’t control it. Logical right?

      Exactly!! Before I came to the USA, I drank milk straight from the cow that was in a pasture all day eating grass, had No problems with milk. I come here and can’t touch anything with milk, I’m allergic. What??? Never before was I allergic. I thought the USA was going to baa a better life, but I learned the government has to control everything here too. It’s a shame.
