Why Humans Drink (RAW) Milk

Why Did Ancient Humans Start Consuming Milk From Other Mammals?

10,000 years ago, early humans spent much of their time hunting, gathering, or fishing for food. Obtaining food was the dominant preoccupation of their lives. Imagine the reality for humans living prior to the advent of civilization. You can picture them living in crude shelters, wearing animal skins and using few tools. It was not like a 14-day survival challenge where they could call for a medic and be rescued. Eating and surviving were lifelong challenges.

You can hear the crying of babies and children that were hungry. Those cries are universal and have not changed over the millennia. The natural instinct to provide for the next generation was a compelling mandate which drove instinctual and natural innovation.

Early humans nursed their young, just as all mammals do. Nursing provided optimal nutrition for babies to survive and thrive. Breastmilk is a form of raw milk, serving as a complete food source that is perfectly designed to sustain life.

People observed animals in the wild nursing their young just as they nursed their own young. By capturing goats and aurochs (ancestral cow breeds), the people were able to collect their milk in pottery vessels. These humans would have learned quickly that milk from other animals was a complete, nutritious food. Being purposely designed to sustain life like no other food, this raw milk provided a steady source of readily available food for ancient humans.

Without refrigeration, any milk that wasn’t consumed quickly would naturally ferment into cheese curd and whey. The milk storage vessels likely contained bacteria cultures from previous milkings, and hence the culturing process was naturally reinforced with these bacteria.  The resultant curds could be stored and consumed over time. Curd contained a complete set of microbiome-friendly nutrients, and would be easy to digest due to its biodiversity. The humans could now bring along with them a portable supply of steady food. As long as they had sunshine, water, grass or shrubbery, and a mammal, they had food.  

Scientists have ample evidence that humans began drinking raw milk from animals at least 10,000 years ago. The evidence for the early use of animal milk is found in ancient clay pottery vessels, dental remains of Neolithic humans, and bone analysis of animal remains. Ancient baby bottles provide evidence that milk from animals was used to feed human infants at least 8,000 years ago.

These agriculture-based civilizations were so successful that they spread across the Mediterranean region, Europe, Asia, and the Middle East over the next few thousand years. Humanity continued to domesticate additional species of animals; throughout history, many species have been utilized for their milk including camels, cows, goats, sheep, donkeys, horses, water buffalo, reindeer, and other mammals.

Those who consumed milk had a competitive advantage over those that did not have a steady source of readily available food.  This steady supply of food allowed for settlements and communities to develop. People no longer had to spend most of their time acquiring food, and could instead use their brain power to drive the development of sophisticated structures and towns. Domesticated animals became high value assets. As civilization advanced, those that owned milking mammals became wealthy and became the source of food for communities.

Lactase and Genetic Adaptations for Milk

The domestication of mammals and consumption of their raw milk provided a source of biodiverse colonies of bacteria for the human gut. When people began drinking raw milk at least 10,000 years ago, these biodiverse bacteria began the genomic adaptation for lactase production and lactase persistence genes. Lactase is the enzyme responsible for breaking down lactose into digestible form. 

Humans who first began to consume milk from other mammals had not yet developed the lactase persistence gene. Nonetheless, they likely would have been able to readily digest raw milk because it facilitates the production of lactase enzyme in the intestinal tract. Archaeological evidence shows that humans were consuming raw milk for thousands of years before the widespread appearance of the lactase-persistence gene. This has led many researchers to the probably erroneous conclusion that Neolithic humans must have been fermenting or culturing milk to reduce or remove its lactose content.  

In reality, “lactose-intolerance” is primarily pasteurization intolerance.  Since raw milk facilitates the production of lactase, it is not likely that there were widespread issues with lactose intolerance in Neolithic populations. In all likelihood, these early populations would have been able to consume milk in its fresh form straight from the mammals, as well as in the lacto-fermented curds and whey which would form quickly without refrigeration.

The competitive advantage provided by raw milk is not to be understated. Raw milk allowed humans to thrive in conditions where survival would have been difficult. It allowed them to migrate and proliferate from region to region with a steady supply of food. Those populations that consumed milk further adapted by developing lactase-persistence genes. Scientists now believe that the lactase-persistence genes were spread through natural selection. This means that the reproductive capacity and/or survivability of ancient raw milk drinkers was substantially increased compared to non-milk-drinking populations. The lactase-persistence genes would have facilitated the easy digestion of milk in many forms, including boiled or cooked milk. There is current evidence of lactase persistence genes in people from regions of Africa, Europe, Asia, and the Middle East. However, even those without the lactase-persistent gene can generally digest raw milk because of the raw milk bacteria that create lactase for the human gut. 

Pasteurization: A Technological Solution to a Manmade Problem

A 19th century illustration of "swill milk" being produced: a sickly cow being milked while held up by ropes. (Frank Leslie’s Illustrated Weekly)

By the mid-1800’s in America, some raw milk production had shifted away from farms and into highly-populated cities. Big cities did not have pastures or clean water, and the cows in city dairies were kept in filthy conditions with poor nutrition and poor animal health. Many of these cows were fed byproducts from alcohol distilleries, leading to illness in the cows. Raw milk, which had been safely consumed by humans for nearly 10,000 years, had become a source of deadly diseases such as tuberculosis, typhoid, diphtheria, and scarlet fever. 

In the late 1800's, it was recognized that raw milk being produced in these conditions was dangerous, and two solutions were proposed.  Pasteurization was one of the solutions which was proposed to eliminate pathogenic bacteria in the milk coming from these filthy conditions. The other solution was to actually produce the milk in hygienic conditions with healthy animals.  

It was known that raw milk was a superior source of nutrition for infants and children, so the American Association of Medical Milk Commissions (AAMMC) was established in the late 1800's to ensure a safe supply of hygienic raw milk. The AAMMC was in operation for nearly a century, certifying medical raw milk for use in hospitals and for feeding infants and children.  

Pasteurization was ushered in to address filthy conditions and unhealthy cows in cities.  It answered the question of how to commercialize dirty milk, rather than spending the time and energy it would take to produce clean milk from healthy cows. Clearly, over time, the pasteurization movement gained traction and became the standard for ensuring "safe" milk, yet pasteurization is known to degrade and damage many of the nutrients in milk. 

Raw Milk’s Role in the 2020’s

Now in the 2020’s, we are in a time of widespread immune depression, comorbidities, and compromised health. For most Americans, the competitive advantage of raw milk consumption has never been a reality. Raw milk’s immune-building properties and microbiome friendly traits have been forgotten. 

Instead, we live in the age of immune-destructive pharmaceuticals and antibiotics. Although life-saving in certain applications, these drugs also depress and damage the immune system and gut microbiome. Antibiotic resistance is now responsible for the deaths of tens of thousands of people every year in the USA alone. Furthermore, pasteurized milk is now recognized as a top food allergen and difficult to digest.  

Raw milk is an innate part of our healthy immune history, and is largely missing in our sterile, sugar-laden, preservative-laced, antibiotic-abusing modern diets and medical culture.  Safe raw milk has been rediscovered by those who study history and know the role of raw milk as a nourishing whole food.  Raw milk that is carefully and intentionally produced for direct human consumption is wholly different from milk being produced for pasteurization.  

So, the next time that someone says, “milk is for cows and not for humans,” share with them the intricate link between civilization and raw milk, and the competitive advantage that raw milk provided to humanity for 10,000 years. Many of these misinformed humans are in dire need of gut microbiome rescue like never before. Reach out to them with love, compassion and humanity. They need our support, nourishment, and education.    

Antibiotic Resistant Genes in Raw Milk - What Does the Data Really Mean?

Government-Funded Study Finds ZERO Pathogens in Raw Milk Samples!

That’s what the headlines should have read.

Instead, the study was titled, “Reservoirs of antimicrobial resistance genes in retail raw milk” [1]. The study, funded by the National Institutes of Health (NIH) and the United States Department of Agriculture (USDA), was not able to find any pathogens in raw milk. So instead they focused on trying to create fear of antibiotic resistant genes which were found to proliferate when raw milk was allowed to sit at room temperature for hours.  

Antibiotic Resistant Genes are Ubiquitous

Antibiotic resistant genes are everywhere. They’ve been found in every environment, including pristine habitats that have been virtually untouched by humans such as Antarctica [2, 3].  They’re even found in the dust of buildings [4].

“Antibiotics are ancient, dating back hundreds of millions of years. Resistance is therefore equally ancient, and the number of genes in the resistome is a reflection of the continuous co-evolution of small molecules in natural environments and microbial genomes.”  

-Gerard Wright, Nature Reviews Microbiology 2007 [3]

Given that they are ubiquitous in the environment, it is no surprise that there are antibiotic resistant genes in many foods [5]. Breast milk, too, contains antibiotic resistant genes carried on bacteria found in the raw breast milk [6].

Breastmilk and Antibiotic Resistant Genes

Researchers in Helsinki found that, even though breast milk contains antibiotic resistant genes, babies who were breast fed actually have less antibiotic resistant genes in their guts than babies who weren’t breastfed or who terminated breastfeeding early [7].  Researchers attribute this benefit to the fact that breastmilk promotes the growth of beneficial bacteria such as bifidobacteria, which can then outcompete the bacteria carrying antibiotic resistant genes. Like breast milk, cow’s milk has also been shown to support the growth of bifidobacterial [8]. 

Potential Dangers of Antibiotic Resistant Genes

Antibiotic resistant genes can pose potential health threats in specific circumstances. When antibiotics are taken, the intestinal microbiome is disrupted as both beneficial and harmful bacteria are killed off. This weakens our immune systems overall [9]. If there are antibiotic resistant bacteria present in the gut, taking antibiotics actually allows these bacteria to proliferate in the absence of competing bacteria. There can then be infection or illness which is not able to be respond to antibiotics. Antibiotic resistance is now responsible for the deaths of tens of thousands of people every year in the USA alone [10].

For example, C. diff. colitis (clostridium difficile colitis) is infection of the colon that results from disruption of the healthy bacteria in the gut, usually as a result of taking antibiotics. C. diff. can cause diarrhea, abdominal pain, fever, bloody stools, kidney failure, and even death. One of the best treatment options for severe C. diff. infections is fecal transplant. Severely ill C. diff. patients have a 92% cure rate from fecal transplants, which provide a healthy flush of poop from a healthy human donor into the colon [11]. The fecal transplant recolonizes the gut with healthy bacteria.

Zero Pathogens in Raw Milk Samples

Coming back to the study funded by the NIH and USDA [1], researchers found that antibiotic resistant genes proliferated in raw milk that was allowed to sit at room temperature for hours.  Their research showed that raw milk which was kept refrigerated had low levels of antibiotic resistant genes.  What this actually demonstrates is that raw milk from around the country is being produced very cleanly, resulting in low bacteria counts.

Most of the potential beneficial bacteria to be found in milk is from either fecal or soil origin. Yes…dirt is very good for you and a little poop does not hurt either [12]. It has long been understood that living in a farm environment has substantial health benefits over living in urban environments [13]. However, in our modern world with immune-compromised consumers, the raw milk standards have had to change.

For raw milk to be legal for sale and safe for the general public (including immune-compromised people), it must be very hygienic. It can no longer have dirt or poop in it. So, all that is left is clean, delicious, safe raw milk from deep inside the cow’s or goat’s udder. The government-funded study tested retail raw milk samples and they found ZERO pathogens! This should be celebrated as true progress towards farm cleanliness and testing.

“[Raw] milk samples in the present study were screened for Listeria spp., Salmonella enterica, and E. coli O157:H7. None were detected.”

-Liu et al. Microbiome 2020 [1]

Fermenting Raw Milk

For thousands of years, people have known how to ferment or “clabber” raw milk by simply leaving it at room temperature instead of refrigerating it.  In the absence of refrigeration, traditional cultures often consumed raw milk in fermented form [14]. Such milk would have contained ample beneficial lactic acid bacteria from the small amounts of dirt or manure that would have been present on the udders and teats of the milk animals, and would therefore quickly ferment at room temperature. 

In modern times, people have largely lost their taste for spontaneously fermented, sour raw milk. Raw milk farmers and consumers aim to maintain the sweet flavor of fresh milk as long as possible. The farmers do this by thoroughly cleaning the udders and milking equipment to ensure the milk will have low bacteria counts [15], as well as by rapidly chilling the milk and keeping it cold.  Consumers, too, work to make sure their raw milk is kept cold, even during transport.  Keeping raw milk cold allows it to retain its sweet taste and gives it a longer shelf life.

One useful point of information from the government-funded study was the finding that “spontaneous fermentation does not grow beneficial lactic acid bacteria”. This means that the very clean, low-bacteria count raw milk which is currently available in the USA may not ferment very well in the traditional way. The flavor of spontaneously fermented raw milk is not generally palatable to the modern raw milk consumer. Thus, most raw milk consumers actually work to make sure that their raw milk does not ferment and stays fresh and sweet.

Generally, raw milk consumers who intentionally ferment their milk will do so by adding beneficial bacteria such as yogurt starter or kefir grains. Kefir, in particular, is associated with a wide number of health benefits including lower blood pressure, decreased insulin resistance, tumor suppression and prevention, and improved composition of the gut microbiota [16-19].

The Bottom Line

The NIH and USDA-funded study found no pathogens in raw milk. This is further confirmation of the findings published in the January 2020 Journal of Epidemiology and Infection which concluded that “raw milk can be produced with a high level of hygiene and safety” [20].

The government-funded study focused on antibiotic resistant genes which can proliferate in raw milk that is left at room temperature for hours. However, it is no surprise that raw milk, like breastmilk and many other foods, contains antibiotic resistant genes. The presence of antibiotic resistant genes is not an issue unless the balance of good bacteria in the gut gets disrupted. Both breastmilk and raw milk are known to promote the growth of beneficial bacteria such as bifidobacteria. The study completely ignored the growing body of evidence that has shown that children who drink raw milk have decreased rates of asthma, allergies, eczema, ear infections, fever, and respiratory infections [21-23].

The best way to beat antibiotic resistant bacteria is to protect and nourish the biodiverse bacteria in the gut. You can do this by avoiding antibiotics and processed foods, which damage the gut and immune system [24, 25]. Instead, eat plenty of whole foods such as raw milk, milk kefir, grassfed beef, eggs, and fresh or fermented vegetables and fruits to feed the beneficial bacteria in the gut and allow it to thrive [26].

Immunity, the Immune System, and Raw Milk

Four Variables for Pathogenic Illness

Masks, social distancing, handwashing, testing: in the last few months, America has awoken to a whole new reality with an awareness that a compromised immune system is risky and dangerous. We are now talking about immune systems and compromised immunity like never before.  Yet, we haven’t been talking about host immunity, and why people have compromised immune systems.

We are the HOST and we have an immune system that protects us if it is strong. Bacterial, fungal, and viral pathogens need a host to survive and thrive, yet pathogens do not cause illness in every host. Scientists and doctors agree that in order for a pathogen to cause illness, four variables must align:

• A pathogen must be present

• The pathogen must be virulent and capable of producing harmful effects

• The pathogen load must be high enough

• The HOST  must be susceptible to the pathogen

Misplaced Focus on Compromised Immune Systems

Health professionals and the news media have avoided  discussion of our host immune systems, which naturally protect us all the time from pathogenic threats. Instead, they talk about how people with compromised immune systems and comorbidities (such as high blood pressure, diabetes, heart disease, and obesity) are being disproportionally affected by COVID19. Our American lifestyle and diet has predisposed large swaths of our population to having compromised immune systems and comorbidities.

Masks and social distancing aim to reduce the pathogen load, yet this narrative neglects the superior aim of strengthening the host. We have little  control over the strength of the COVID19 pathogen, and we can’t live behind masks forever, as we attempt to reduce pathogen load by social distancing and mask wearing  But what we can do is strengthen the host, and that means strengthening our own immune systems.

The best way to immunity is through

strong immune systems.

It is rare that healthy people with strong immune systems are significantly sickened by COVID19. As more and more antibody testing is performed on broad sectors of our population, it is being found that huge numbers of people already have COVID19 antibodies, even though they had no idea that they’d been exposed.  COVID19 has already become part of their adaptive immune response. “Herd immunity” is building whether we stand six feet apart, wash our hands or wear a mask….it is happening whether we like it or not.  The bigger question is: Are Americans up to facing this HOST threat?

Immune System Primer

The immune system is our body’s defense system that protects us from foreign invaders such as pathogenic bacteria and viruses. Immunity is developed by the immune system, and provides protection against illness from specific pathogens. Immunity from specific illnesses is achieved through both the innate and adaptive immune systems.

Image from MicrobeNotes.com

The innate immune system is a rapid–response, whole body protective system that blocks, controls, neutralizes and eliminates pathogenic threats. Elements of the innate immune system include our skin, white blood cells, killer T cells, the gut microbiome, mucus producing cells, tear duct lactoferrin, mucus membranes, lymphocytes, phagocytes, MAST cells, and cytokines. Our innate immune systems  protect us all the time if they are strong and functioning well. The very last thing you would ever want to do is injure or disable this system. Yet, that is exactly what we do whenever we take symptom relief medications which block mucus production or other natural systems that protect us. Antibiotics have been abused so badly that we now have tens of thousands of people that die every year from antibiotic-resistant bacteria. Our first-world innate immune systems and microbiomes have been damaged and  can no longer protect us.

The adaptive immune system is a slow-response system that creates specific immunity after the innate immune system has been the first line of defense. The adaptive immune system creates a long-term memory of the invader, thereby producing specialized antibodies against each specific invader. Antibodies can be likened to battle-hardened, experienced warriors who are ready to quickly protect against any similar attack that may come your way in the future. 

Vaccines aim to trick the body by introducing dead or weakened pathogens in an attempt to trigger the adaptive immune system to produce antibodies. It is possible to create immunity to a pathogen through vaccination and allowing antibodies to be created by your body’s adaptive immune response. Sometimes this works and sometimes it does not.

Creating antibodies means you must go to battle. Going into battle with a weak immune system is a serious risk! Having a strong, adaptive and resilient immune system is a powerful barrier to protect against bacterial, viral, and other threats.

We Damage Our Immune Systems

At the foundation of the immune system is the gut microbiome, which houses 70-80% of the immune system. In America we have embraced all sorts of things that weaken the gut microbiome: antibiotics, preservatives, GMOs, Roundup residues, high sugar diets, highly processed foods….these are all destructive to the gut microbiome and therefore they compromise the immune system. For instance, antibiotics weaken the innate immune system by disrupting the gut microbiome such that neutrophils and white blood cells are no longer able to react properly when threats arise. Antibiotics also weaken the adaptive immune system by reducing immunity to subsequent infection. Food additives such as preservatives effect immune cells and the inflammatory response, thus contributing to the development of comorbidities. Over the longer life experience, exposure to these foods and threats often manifests as chronic disease including diabetes, obesity, arthritis, asthma, whole body inflammation, heart disease etc.

Raw Milk and Milk Kefir Strengthen the Immune System

Nutrition is of prime importance in strengthening the immune system. Raw milk plays a very important part in building and strengthening both the innate and adaptive immune systems. Studies performed in Europe have shown that children who drink raw milk have decreased rates of asthma, allergies, eczema, ear infections, fever, and respiratory infections. These benefits are likely related to the active immune factors, biodiversity, prebiotics, intact protective proteins and other elements found in raw milk. Pasteurized milk does not confer these protective properties because the beneficial raw proteins and enzyme-based elements are denatured and inactivated by heat. Raw milk also contains antibodies which can be beneficial for the immune system.

Raw milk kefir is packed full of biodiversity and contains immune factors from the raw milk. Raw milk kefir is a powerful immune-building food which has been shown to stimulate and modulate the immune system, have a beneficial effect on the composition of the gut microbiome, and reduce allergies. Fermented milk has also been shown to reduce the duration of respiratory infections and colds in the elderly.

Raw Milk Is Similar to Breastmilk

Researchers have likened the protective effects of raw milk to those of breastmilk. Breastmilk is raw milk! Many “agents with beneficial anti-microbial or immune-modulatory effects are shared in bovine and human milk, such as immunoglobulins, cytokines, growth factors, lactoferrin, oligosaccharides, and milk fat globule membranes.”

A recent study of breastmilk from mothers with COVID19 in New York found that the breastmilk contained antibodies to COVID19. This means that infants of mothers infected with COVID19 would receive immunity-building properties directly through breastmilk. Similar effects have been demonstrated with hyperimmune cow’s milk, which has been shown to contain specific antibodies that may boost the immune system. When cows are purposely exposed to pathogens during the dry period, their colostrum contains antibodies to those pathogens for their calves at birth. Research at UC Davis is now investigating whether hyper-immune milk can be produced to protect humans from COVID19.

Raw milk is the first food of life. Its role is not just nourishment; raw milk protects the baby by building the immune system and contributing to a powerful gut microbiome. Over thousands of years of evolution, raw milk has been tested and refined by the trials of successive generations which allow only the best to thrive. The numerous immune system factors present in raw milk intentionally strengthen the baby’s weak immune system, with elements needed for both the innate and adaptive immune systems.

Personal Responsibility for Our Immune Systems

Personal responsibility is critical in building strong immune systems. A strong gut microbiome should be the goal of anyone looking for long-term immune system strength and the subsequent immunity that this brings. Doctors cannot help us with this. We must take responsibility for our own health by purposely building and keeping our immune systems strong. We can care for our gut microbiomes by providing them with whole foods which nourish our biodiversity. Like breastmilk, raw milk and raw milk kefir are self-contained immune system building super foods. Four variables must align in order for a pathogen to make you sick. You have control over the HOST variable and perhaps can reduce the load variable. You are very much in charge of your health and your ability to adapt to all threats, today and into the future.  Drink up your delicious raw milk and thrive!
