How Grok Got Milk

Dairy, as I’ve discussed, is a somewhat hazy matter in the Primal Blueprint. With adequate reasons from solid thinkers both for and against, I’ve relegated dairy to the provisional, the peripheral, the speculative even as I choose to modestly indulge in it. As with most Primal gray areas, some forms appear less controversial than others. Raw, fermented, full fat dairy offers much more health benefit with fewer reservations than processed, low fat renderings. (Isn’t that always the case?) From a Primal perspective, however, dairy still remains somewhat of an enigma. Hardly one of the original, universal foods in human evolution, milk entered the scene at a surprisingly late date – only some 9,000 years ago with the advent of animal domestication. Researchers have long traced the “progression” of Grok‘s dairy intake from the Middle East into Europe, where milk actually became an unusually significant dietary staple. New research into the dairy “drift” now offers more details than ever surrounding this relatively isolated, albeit dramatic, evolutionary event.

Dairy herding, experts believe, took off some 9,000 years ago in present day Iran as a natural extension of the unfolding Agricultural Revolution. The first dairy farmers apparently used goats’ milk before they took on the hefty job of domesticating the rather large wild cattle in the region. (Probably not a bad idea.) Recently, however, archeologists have stumbled upon discoveries that illustrate a fuller and unexpected picture of these first farmers. Excavations around Anatolia (part of modern day Turkey) suggest that these early farmers truly settled more long-term than previously thought. For nearly 2,000 years, this population stayed put rather than migrated further into new territory. (Talk about home bodies.) Not even the coastal areas around Anatolia reveal any evidence of the farmers’ relocation during this period. The spread of dairy herding was apparently a slower and more selective process than previously thought.

Researchers have also been surprised by another new discovery based on Neolithic bones from Turkey. Despite the long-time establishment of dairy herding, the recovered bones of this Mesopotamian farm population didn’t indicate lactose tolerance. (Yes, do the double take.) Apparently, they didn’t like the milk itself but used it to make fermented, no-lactose products like yogurt, kefir and cheese. Their consumption pattern differs dramatically from that of Europeans after dairy herding spread throughout Northern regions.

The question of when and how dairy consumption (as well as lactose tolerance) later developed in Europe has been less than clear, but recent research is overturning old assumptions. Experts have known that farmers from the Middle East region eventually moved northward. As a result of their immigration/influence, herding caught on throughout much of Europe and added a novel and key component to the Northern European diet. Prevailing thought has centered on the notion of peaceful collaboration between the new herding settlers and existing hunter-gatherer inhabitants. The Stone Age hunter-gatherers, many experts agreed, must have learned dairy farming from the immigrant groups.

Newer interpretations, however, illustrate a less collaborative, more contentious series of events. Although the early farmers made their way in fits and starts through Southeastern Europe, their spread eventually (between 7000 and 5500 BC) took on a surprisingly swift, more massive and definitive nature. The movement seemed to have turned on an evolutionary dime. This time frame, significantly, coincided with the advent of true milk consumption– initially in the region of modern-day Austria and Hungary and then gradually throughout Northern Europe. The new farming population and its migration was – in this time period, in this new land – shaped by the milk mutation often called lactase persistence, the genetic “mistake” in which early life lactase production never shuts off.

In the Northern reaches of Europe, the new ability to drink milk introduced a whole new food supply that could sustain humans throughout the long hard winters and through the unpredictable famines. It also offered an additional key source of vitamin D. The colder temperatures in the Northern regions allowed for better storage conditions, a circumstance that likely encouraged consumption. Those who had the mutation won out in the immigrant farmer group because they and their children had a better chance of survival.

Previous theory suggested the gradual interbreeding of the immigrant group with existing hunter-gatherers. Not so, say researchers now. In addition to the grisly discovery of a Neolithic Age mass grave (the remains in which indicate violent beating and bludgeoning), bones from the period reveal two distinct genetic lines, one lactose tolerant (the farmer immigrants) and the other not (existing hunter-gatherers that had come to Europe some 46,000 years prior). Archeological remains confirm that modern day Northern Europeans are descended from that immigrant farming group. With evidence of a wholly different culture, religion and language, the settlers apparently resisted rather than absorbed the original population, and their genetic line as well as agricultural practices, eventually won out. Today, the genetic pattern lingers. Lactose tolerance levels increase in a northwesterly progression across Northern and Western Europe and into the Northwest tip of Africa, where lactose tolerance hits a peak 80%.

Fascinating stuff, eh? So, do the tales of dietary-based segregation and mass graves change my stance on dairy? No. The truth is, I just love the history. Evolutionary drama floats my boat, and I know a few of you out there dig it, too. As for the PB, these recent insights simply offer more confirmation that dairy tolerance follows some vast genetic patterns but ultimately comes down to very personal factors.

Although many populations throughout the world have eaten small amounts of fermented dairy for millennia, the hub of overall dairy consumption – both fermented and nonfermented – was, generally speaking, Europe – and mostly Northern Europe at that. Yes, if your ancestors hail from these regions, you have a greater probability of being lactose tolerant, but 80% is still 80%. That residual 20% is nothing to shake a stick at. (And speaks nothing of casein tolerance.) That means plenty of people as thoroughly Norwegian as can be, for example, will find themselves making frequent restroom trips after a double scoop ice cream cone (not the only reason to skip the ice cream, of course). As for the vast majority of the world’s population, pockets of 0% lactose tolerance certainly exist, but there are plenty of exceptions to the “rule.” It’s yet another reason to gravitate toward fermented dairy (as well as raw and grass-fed whenever possible). Finally, it’s also compelling reason to formally examine your dairy tolerance with an experimental period of abstinence or – on the flip-side – a cautious sample of pastured cream or aged cheese if you’re really inclined.

The world, the modern world in particular, is a big and complex place. Geography doesn’t tell the whole story. As for the researchers’ map, it illustrates impressive waves of migratory patterns and population-based gradations, but it’s hardly a measure or prediction of individual experience. Nonetheless, our respective ancestors live somewhere in the shadows of that cartographic tale, as sweeping and suggestive it is of the tumult those groups lived through. Evolutionary happenstance makes for an intriguing design – from a safe distance.

  4. I tried Greek yogurt for the first time this week, and noticed I was running to the bathroom not an hour later. Maybe I’m lactose intolerant, and did not realize it?

    • Greek yogurt has twice the protein, does it also have twice the lactose, which is a carb?

      Joan wrote on October 26th, 2010
      • Greek yogurt has lower lactose levels than regular yogurt. (and yogurt in general has lower lactose than unfermented milk.)

        Also, the theory goes that some of the probiotics in yogurt make digestion of lactose easier. (And for unpasteurized milk, the lactose-digesting enzymes right there in the milk can help you out.)

        Jenny wrote on October 26th, 2010
    • Yogurt bacteria digest the lactose, producing lactic acid instead – hence the sharp taste. A good yogurt contains live bacteria, meaning that they were added after pasteurization of the milk. Unless the carton says “live cultures” in so many words, the product may be a yogurt-flavoured milk dessert. Greek yogurt has a more fat, because extra cream is added to the milk Some people just don’t handle dairy fats well, others are intolerant of dairy proteins. You may be one of them.

  5. Back in the day, pre-primal I used to consume 3-6 8 oz. glasses of milk per day. I LOVED milk. I always had an ENOURMOUS glass with dinner and lunch and poured it on my cereal for breakfast in the morning. It was pasteurized 1/2% or skim milk.

    I also had acne at this time. I suffered with acne for almost 6 years. I read over and over again abou a strong link between dairy and acne.

    I decided to completely stop drinking milk cold turkey. I consumed very little cheese and basically cut out ice cream as well. Over the next few months my acne improved DRAMATICALLY.

    I then went primal in April of this year and within 1-2 months my acne completely evaporated. I once in a while get a teeny tiny whitehead or pimple that goes away within a day or 2. This happens when I eat non primal food.

    Anyone who has a acne and consumes dairy should stop IMMEDIATELY and see what happens over a 30 to 60 day period. There are a lot of factors that go into acne but milk is a HUGE one.

    I enjoy cheese in moderation – sometimes raw and sometimes pasteurized. I still have ice cream once in a great while – I refuse to go the rest of my life without ice cream.

    • Same thing here. I’ve never been a milk drinker but I love everything else that is dairy. In my early 20’s I started getting mild/med acne, I also developed tinea versicolor (white/pink spots on skin). Both healed when I went raw vegan but then I started noticing other problems which led me to paleo/primal. I find that what works best for me is goat milk dairy products, they never give me any problems and also staying away from coffee, tea and chocolate.

I also started taking flaxseed oil every day (in addition to fish oil) to get my omega3:6 ration in check and I noticed a significant change with that too. Sometimes acne can be just a manifestation of inflammation in a diet too high in omega 6

      • For me it’s eczema. I used to get very little dairy but I had a bit of acne and eczema flared up often on the insides of my elbows and backs of my knees. When I went paleo and cut out the gluten, it disappeared. Then I added in more dairy to make up for the carb calories I wasn’t getting (I need a LOT of calories) and the eczema came back. I’m not sure if it’s a casein or lactose issue, but I’m suspecting lactose since I was still eating plenty of low-lactose hard cheeses when the eczema originally disappeared.

Haven’t noticed any issues. Btw, I’ve spent long periods drinking milk substitutes such as almond milk. Didn’t really notice any changes with regards to skin or respiratory-related issues. I am back to dairy again but the lower fat versions as saturated fat raises my cholesterol.

  6. I drink raw goat milk. Get it from a local producer. I also get from him Kefir and Yogurt. I’m going to try my hand at making my own cheese this weekend.
    Goat milk has very little casein. So if there is a problem with that, you pretty much avoid it with goat milk.

  7. A few comments relating this article to grains.

    During my gluten research, I came across sources that said often gluten issues can mask as lactose intolerance. Stop the grains, and after a healing period lactose is no longer a problem for some. I believe I am one of those people. My heritage is mostly Belgian, with many ancestors being dairy farmers.

    My second comment relates to what seems like a flaw in the paleo argument. Let me say up front I am paleo + dairy, completely grain-free. The flaw to me is the argument that humans have not had time to evolve to eat grains, when clearly humans did evolve to eat dairy in a very short time. The paleo grain argument also says agriculture removed natural selection from the equation, so essentially stopped evolution, because from a genetic standpoint, who cares if you have middle-aged grain-related health problems — you’ve already reproduced. But this dairy evidence appears to show agriculture did not stop evolution, in fact it sped evolution in this case.

    Paul C wrote on October 26th, 2010
    • Don’t forget that we are also mammals and have a certain biological affinity for “dairy” type chemicals in the first place. While cow milk is obviously not human milk, there is still much more of an evolutionary link.

      Neil wrote on October 26th, 2010
      • Neil I believe you are likely right. A mutation to continue using lactose past infancy is of course more simple than recreating an entire digestive system, which is probably what it would take to digest grains properly.

        Paul C wrote on October 26th, 2010
        • I also am not convinced at the natural selection and evolution coming to a halt theory.

          for one thing, who has kids at a young age these days? it does happen but the age people reproduce these days seems to be getting higher due to career goals among other things. by the time most people have kids any symptoms would have arrisen and thereby effect natural selection.

          you can’t tell me that someone with all kinds of health problems (caused by grains) is going to get chosen for a mate over someone who eats grains and is uneffected and appears in good health. not from a biological point of view anyway.

          I can tell you right now, people who can tollerate anything they consume are more attractive. it’s just the way it is.

          i’ve never heard anyone ever comment on how sexy someones food intolerances are! but conversely people are intuitively attracted to people with no intolerances.

          who’s to say that the person with the health problems will actually find a mate and reproduce? is it not likely that they don’t ever reproduce, thereby allowing evolution to favor the ones who are better able to tolerate grains and eventually eliminate everyone else?

          I think it is. I think you can’t stop evolution.

          anyone else have any thoughts on this? or any opposing views or reasons why this could be wrong?

          Michael wrote on November 26th, 2010
    • Grains also have toxins to keep from being eaten – milk doesn’t (although if you’re lactose-intolerant I suppose you might think that toxic enough).

      jade wrote on October 29th, 2010
    • Neoteny is a trait where-in Juvenal characteristics are retained into adulthood and beyond, it accounts for the development of our brains and the angle of our heads to our necks. As infants and children our bodies INNATELY have the ability to digest milk since WAY back in the day. However grains were never part of the picture. So our “rapid” evolutionary ability to retain a characteristic of youth is much easier/possible on an evolutionary scale than adding in a completely foreign body to our diet.

  9. Great post.

    I have to honestly say that once I cut dairy, bread, and refined sugars out of my diet. I was able to lose 70lbs in 4 months.

    So I say NO to dairy.


    My 90 Day Fitness Journey wrote on October 26th, 2010
    • But how do you know cutting dairy had a part to play in your weight loss? I’m not for or against dairy, but I think all variables have to be in treated isolation to come to a conclusion for oneself.

      The same kind of conclusions are often made by vegan people who cut meat, sugar and processed food, start feeling better and attribute it to the fact that they cut meat. They would just have to try to ad meat to their veggie diet and they would see pretty fast that meat isn’t a problem.

      I’m not saying though that cutting dairy didn’t help in your case, just to test it out on its own.

      For myself, for example, going a little overboard on the homemade goat yogurt made me discover that I’m lacking magnesium because some digestive symptoms became worst, but didn’t come back to normal after stopping the yogurt. I also started to experience spasms in my gut, very uncomfortable let me tell you.

      I made 1 and 1 together. Problems with electrolyte balance, especially magnesium, can lead to spasms and yogurt is full of calcium, which is antagonist to magnesium. Surely, when I took care of getting more magnesium, the spasms went away.

        I’m at normal weight 5’10” 145 american lbs…I’m not gaining weight either.

        But when I don’t have access to raw milk for 2-3 days I am less lethargic, feel thinner and drop about 2-4 lbs.
        The weight loss is because I eat the same amount of foods, but calories from milk has been stopped. After about the 3rd day of still not having milk my food consumption goes up…and weight goes back to the same.

    • You also cut out bread and refined sugar – so there’s no way to attribute your original 70lb of overweight to dairy. The only way to be sure it was dairy products to blame would be if you now eat bread and refined sugar in greater amounts than before you changed your diet – greater amounts because you have to make up for the calories that you used to get from dairy foods – and are able to maintain your low weight or continue to lose weight.

  11. “Previous theory suggested the gradual interbreeding of the immigrant group with existing hunter-gatherers. Not so, say researchers now.”

    Actually, even the link you give doesn’t make such a sweeping claim. It says:

    “We conclude that this difference in frequency could not have arisen by genetic drift and is either due to selection or, more likely, replacement of hunter-gatherer populations by sedentary agriculturalists.”

    So they conclude replacement is “more likely” – not such a strong conclusion as you said. In addition, that paper is claiming this _solely_ on the basis of an allele “associated with lactase persistence”. That’s hardly a very full consideration of the genetic evidence.

    Three maternal gene groups from the Near East are thought to represent people arriving in Neolithic times- J, T1, and U3. They amount to around 20% of the European mitochondrial DNA pool. That’s a fair bit but hardly evidence for replacement. And some LBK pottery finds and so on can only take us so far.

        • A fair question, Lynn:) In my case, it was pretty easy to tell – I live on disability for depression, anxiety, and OCD. I haven’t taken pharmaceuticals of any kind for years, so they’re not part of the equation. I had added sharp cheddar cheese to my meals for added fat. Over months I began to suspect my symptoms were worsening, and finally I decided to stop the cheese and see. Within a week my increased irritability, fatigue, and obsessiveness lifted, it was an incredible difference. To my knowledge, lactose doesn’t affect mental state, but casein is known to be very problematic in this way. So why did I add it for fat when I had some idea of this? Well, we all do stupid things sometimes:) Could I still be lactose intolerant as well, and never knew it? Sure. As a matter of fact, another thing that went away was a heavy feeling in my stomach after meals, and some gas during the day that hadn’t been there before. So it’s certainly possible, even though cheddar is a low lactose cheese, and even though it wasn’t a really violent reaction as some people experience. But, as you see, the bigger problem for me would seem to be the casein. ‘Hope that answers your question:)

Most self proclaimed lactose intolerant can drink raw dairy easily. Also, it’s pasturized dairy that causes the mucus, not raw. Mucus is a sign on intolerance after eating any kind of food your body doesn’t really recognize.

    And let me just mention the wonders of RAW cream. Like heaven on earth!

    • Mindi, raw milk post-workout doesn’t do much. It’s mostly casein and a bit of whey and the fat slows down absorption even more. It would be a few hours before your body even breaks it down to amino acids. You could try a good whey isolate or branched chain amino acids.

  18. Love reading the history too – thanks for the post. It’s fascinating that we can study genes to discover who our ancestors really were. For instance, the black Irish – mythological descendants from an Iberian king. Turns out the Irish, especially those from the west coast, are genetically related to people in Northwest Spain and Portugal, descendants of celtic people who migrated there over 4000 years ago. Dairy farmers, I wonder?

    Joan wrote on October 26th, 2010
    • My understanding was that the Black Irish are descended from Spanish sailors shipwrecked when the Armada was defeated by the English in 1588. However, the earlier migration makes sense, too.
      When the Vikings invaded Ireland they left behind their Scandinavian genes, including those for the light-colored hair (the “light foreigners”) and I’m betting they brought lactose tolerance, too. The dairy products in Ireland were to die for, whether it was milk, butter, or ice cream; thinking that such wonderfulness would have not been developed in a largely lactose-intolerant population.

No more lactose tablets. It’s amazing. Lost 44 lbs on PB using whole milk in my whey protein drink and having cremefresh every single night on my berries. But, if I have ice cream or non raw or melted cheese, yes trouble. Try finding that milk milk and see if your life doesn’t change. Sometimes called cream top milk.

  22. Sheep Milk > Goats Milk > Cow Milk

    I truly believe that almost no one can say that they can’t digest milk when they haven’t tried raw, grass fed, hand milked, glass bottled sheeps milk. The nutrition profile is ridiculous. Almost 15 grams of fat per 8 ounce glass! Cow milk has 8!

    Try it groks! It tastes unbelievable.

  24. I love butter and cream. I have a mixed heritageand besides milk most dairy does not give me problems. I have thought of going off dairy for a while to see if this will help with weight loss but have yet to make up my mind. The reason some may find it hard to get their raw dairy now is that the USDA is on the war path again and has it in for raw dairy. They are terrorizing these small farms out of existance. If this happens I will not be eating any dairy as the only dairy I will eat now is grass feed pastured raw dairy.

  25. I eat dairy everyday. Sometimes grass-fed heavy whipping cream in my coffee, most times not from grass-fed sources (Organic Valley). Definitely cheese and a glass of wine most nights of the week and ALWAYS some form of cheese with my eggs in the morning or a salad at lunch. I’ve taken dairy out of my diet before for a rather lengthy period of time and never noticed a difference. I’ll be keeping it in. Good article!

  27. I noticed long ago that I felt best in my last years of high school, in which, in addition to being young and full of energy, I was singing competitively and competing in track (field/jumping events & no more than 300m sprints, so no chronic cardio). To keep my voice in tip-top shape I had to eliminate dairy and, sadly, chocolate and caffeine. To stay in track form and make weight for pole vault, I had to cut out the calorie-laden grains and focus on veg and meat, with fruit right before practice for quick energy. I guess my body figured out what was best for it before I read all the literature!

  28. I recall reading this article that many cultures don’t understand the US consumption of milk. I remember distinctly it saying that besides breastfeeding, milk should not be consumed for health or nutrition beyond that.
    As far as the animals that do produce milk, shouldn’t that be to nurse their young?

  29. Mark,in Spencer Wells’ book “Pandora’s Seed” he states that Europeans are now 90% lactose tolerant.I would also surmise that lactose tolerance may accompany some adaption to casein.The ancient dairy cows produced,I believe,A2 beta casein,which is what dairy tolerant people grew accustomed.Today,much of the dairy is produced by Holstein and freistan cows which produce more milk but the A1 beta casein,which we have not developed a tolerance.So,if milk used to be your friend but that is no longer the case,try switching to milk produced by Jersey,Guernsey,or Brown Swiss cows.It may take some investigating.
    Thanks for your intellectual curosity Mark,and for providing good discussions.Not all Paleo boards are receptive to open discussions.I am Paleo but maintain an open mind.

    • I thought I was lactose intolerant until I came across A2 milk, which is now sold in all major outlets in Western Australia.

      I swear by it. I used to get an upset tummy everytime I drank milk but with A2 that’s disappeared. Absolute lifesaver – it might be twice as expensive as regular milk but I don’t care.

      I heard the other milk producers are trying to bully them out of the market. It’s never about what’s best for people isn’t it?

  30. Pasteurization of milk was one of the biggest mistakes in the dairy industry, along with feeding cows corn/grains.

    |True| milk comes from healthy, organic grass-eating cows that get access to sunlight. Studies have shown that corn-eating cows produce milk high in omega-6 to 3 ratio while grass-fed cows showed the opposite, and contained high amounts of CLA (Conjugated Linoleic Acid).

    Everyone can digest raw, grass-fed milk as it contains the beneficial bacteria and enzymes necessary to digest lactose, the sugar in milk; these enzymes are destroyed by pasteurization, thus leading to intolerance.

    Also many people are afraid of the saturated fats in dairy. You should not be afraid of fats from grass-fed cows as 1)they are very high in omega-3 (boosts metabolism), and
    2)the fats are sent directly to the liver as energy use rather than fat storage
    3)a documentary showed that a morbidly obese man who started consuming dairy from grass-fed cows lost over 100 pounds due to the high metabolism rate acquired from eating high amounts of omega-3 fatty acids from butter (milk fat). He actually consumed just over 2,000 calories just from butter a day. Just from butter. And yes, he did eat meat (grass-fed) and vegetables, etc.

    Raw milk is the way to go.

  31. This has probably been touched on by smarter folks than me, so if this is redundant, forgive me. But it seems that a hunter would kill a nursing female animal from time to time and maybe end up eating everything, including the udder and its contents. Maybe this was infrequent, or maybe not as nursing mothers and their young may have been easier targets.

    Whether it was frequent enough to create lactose tolerance, I don’t know. But it always comes to mind when the milk debate comes up.

    Patrick wrote on October 26th, 2010
    • There have been wonderful stories of people with lactose intolerance having success with raw milk because it retains the enzymes needed to digest lactose otherwise destroyed by pasteurization! 😀

    • Also:

      Most of the people that are a rare blood type (B-, A- and AB-) have 2 extra small ribs at the bottom of the rib cage not fully attached to the rib cage yet.
      I know so because my entire family has them, we are all a rare blood type on both sides of the family and we all produce our own lactose enzyme.
      (Had blood test done).

      My believe is that the extra intake of calcium coming from drinking animals milk for thousands of years (before the ‘true’ agriculture era was recorded) made it possible for some of us to grow additional bones.

      People had pet dogs (oldest recorded 35000 years ago, grave found in Belgium, center of an old village) thousands of years ago before actual farming practices were recorded…now why would we have dogs but not capture the prey, especially when the mother was killed and the little one would stand there in shock. We had prey as pets WAAAAY before agriculture.

  32. This is my first post on this website so let me know if I’m out of line on this one. “Are we not the only mammal on the planet that drinks another mammals milk?” The answer to this question leads me too believe that dairy should be used very sparingly if not at all after you have received the nutrients needed from our mother.

  33. (I accidentally posted this on your other milk post, meant to post this here)

    My wife is purebred Norwegian and absolutely loves milk, she drinks an organic lightly pasteurized un-homogenized glass bottled milk; about half a liter+ a day especially at dinner time.

    I think being un-homogenized is most important besides being organic. Before I married I dated several black women from Haiti and Kenya and all of them boiled their milk before they drank it, both in preparing it with tea and at night mixed with wild honey. They thought it was strange to drink “cold” milk.

    I myself prefer Kefir. My wife and I have been living in Europe since 2006, I don’t really drink “cold” milk but when I lived in the States I couldn’t tolerate the milk there at all, over here dairy is a different story as far as quality and while the lactose doesn’t bother me the least bit I can always feel the insulin spike which is why I usually only drink organic Kefir and warm milk w/ no problems.

    I would like to clear one thing up though, there is a rumor that EU countries have great access to raw milk, that’s not the case it’s just like in the States; you have to goto a certified farmer or the private store the farmer owns. You can definitely get un-homogenized milk though and also cheeses and butters made from raw unpasteurized milk but not actual milk. Every single person I’ve asked about unpasteurized milk here has given me your an idiot look.

    My great grandmother from Okinawa is 104 and her daughter (my grandma) is 81 or 2 and they drink warm milk.

  34. Great discussion, Groks.
    For the milk / acne connection look at and
    Many will note that many of us can consume as much dairy as they wish with no acne. Lucky genes.
    But if you have the genes to make acne, dairy is not your dish.

    wikiderm wrote on October 27th, 2010
  35. I loved your article, Mark. Most interesting!

    I fall somewhere in the camp of “I dunno”. We have a raw milk share from a farmer that only pastures his beef and dairy cattle. The milk/cream/butter/cheese we get from him is divine. But, like a lot of other people on this board, I had horrible acne from pasteurized milk when I was a teenager and I seem to be sensitive to even raw milk now.

    That said, the milk we get is transformed into kefir and different types of yoghurts. I do make a warm milk drink for my kids that has whole milk with raw butter, cardamom pods, cinnamon, and nutmeg stirred into it and is then warmed in a pot. They drink this “butter tea” on cool evenings or post- hockey.

    Before we got our milk share, I tried our kids on pasteurized, non-homogenized, organic milk. All of them reacted to it (the teenagers got acne and the little one got sniffly). If we don’t have pastured, raw, we just avoid it entirely.

  36. The ‘no other animal consumes milk beyond infancy so neither should we’ argument always comes up. I think there’s another way to look at it – milk is the only substance that is specifically designed and intended to be consumed (except maybe fruits). OK, maybe it’s intended to be consumed by infants, but that’s still consumption. Pretty much anything else DOESN’T want to be consumed, and evolves strategies to avoid it. Would mammals have evolved a way of making their milk simultaneously nourishing to their own young but toxic to any other animal? Anything is possible, I suppose, but it’s surely a lot more tricky than outright toxicity.

  37. What a great post. I love the discussion and added facts, so interesting. I cut back on milk for thirty days but did not notice a decrease in my acne, which has gotten worse in the last two years (have not found a pattern as to why yet). I am attempting some personal studies on myself to see if I can lessen it. For now i am trying a three month period where I stick to the 80/20 Primal lifestyle which does include half and half in my coffee, occasional ice cream, and cheese. I am starting to track in November to see how it goes.

    • We have tendency to look at things very narrow when give data sets of information on different foods. For instant coffee has a lot of reported benefit with or without the caffeine because of that we have a tendency to exclude it from the health puzzle as a whole. I think perhaps caffeine might just be your personal Kryptonite unless of course you drink “decaf”. I’ll give you some things to think about. Firstly, we know caffeine affects your metabolism, any time that happens there is a possibility that you’ll be more prone to acne. This can certainly explain the reported fact when you decreased your milk intake–if, your caffeine intake stayed the same–then you might have stumbled across a correlation. My wife, when she drinks a lot of milks she has good skin but extra coffee/caffeine equals breakout for her. Same with me, I drink lots of black tea maybe 2-3 cups a day, but coffee for me equals small breakout or weak looking skin but extra milk no breakout. You see? Black tea has caffeine but maybe not so much to disrupt normal cycles, but balance varies from person to person. While the literature doesn’t point to a direct link between caffeine and acne we know because of the effects on the metabolic systems that there is at least a indirect correlation. And so now maybe you can explore this possible link between caffeine and your acne and maybe can be one step closer to a “perfect” solution.

      M. O. Samurai wrote on October 27th, 2010
      • Interesting, I’ve explored this possible link and for me decaf or not it still results in a breakout. Chocolate and to a lesser degree tea also produce the same results. I figured it must be something like tannins or something I don’t really know but if I stay away from those my skin is clear. I’ve also noticed that when I started consuming fermented goat products my skin improved so much. If I consume any dairy from cow’s milk (organic or not) however, I get terrible acne so I stay away.

    • You have to cut it out completely. I’ve read it takes at least two weeks to stop having an effect. Try a 30 day challenge, then re-introduce slowly. That should tell you if it’s the milk. It was for me.
