Let’s Consider The Benefits Of Raw Milk

As reported this past week in the New York Times and elsewhere, more than half the states in the U.S. now allow the sale of raw milk. In some states, you can only buy raw milk at a farm, but in 14 states you can buy it in stores.

So why are some people excited about raw milk? Well, the implication is that if’ it’s less processed, it must be better, right? After all, we learned recently that ultra-processed foods are pretty bad for you. (There’s pretty good evidence for that.) And milk is one of those products that people associate with health. For the first few months of life, we humans live entirely on milk–but that’s milk from a woman’s breast.

Cow milk is a different matter. It’s not nearly so, shall we say, clean.

It only took a minute for me to find claims that raw milk has all kinds of benefits: supposedly it helps you digest food better, it has more vitamins and minerals, it boosts your immune system, and it’s better for people with lactose intolerance. (I won’t link to any of those claims because they’re all bogus, and I don’t want to give scammers any more web traffic.)

Before listing some of the special properties of raw milk, let’s consider how it’s processed. The main thing we do to milk is pasteurization: a very simple process where the milk is heated just enough to kill any bacteria in it. It’s not boiled, and the mild heating doesn’t destroy any of milk’s nutrients.

Pasteurization is named after the French scientist Louis Pasteur, who invented the process in the 1860s. Originally it was used to preserve wine, but people eventually discovered it worked just as well for milk and other foods. Back in the 1860s, people didn’t even know that bacteria caused disease, and Pasteur was one of the pioneers who figured that out.

So what does raw milk have in it? Well, it can carry a long list of delightful bacteria, including the ones that cause tuberculosis, brucellosis, scarlet fever, salmonella. And of course there is E. coli, including strains that can cause terrible diarrhea.

Bacteria just love milk, it turns out. Raw milk is teeming with them, and many of them are really not good for humans. Fortunately for most of us, pasteurization kills bacteria very effectively.

And there’s one more special thing you get in raw milk that you won’t get in pasteurized milk: cow poop. Funny thing, though: on the advertisements I found for the benefits of raw milk, none of them mentioned this.

So sure, get your raw milk and live like it’s 1850 again! Never mind that pasteurization has saved countless millions of lives. Seriously, folks: there’s no reason whatsoever to drink raw milk. And states that allow the sale of raw milk are endangering the health of their own people.
