Introduction
The Weston A. Price Foundation
The Weston A. Price Foundation is a nonprofit, tax-exempt charity founded in 1999 to disseminate the research of nutrition pioneer Dr. Weston Price, whose studies of isolated non-industrialized peoples established the parameters of human health and determined the optimum characteristics for the human diet.
The Foundation is dedicated to restoring nutrient-dense foods to the American diet through education, research and activism and supports a number of movements that contribute to this objective including the establishment of universal access to clean, certified raw milk throughA Campaign for Real Milk www.realmilk.com
An extensive system of local chapters helps consumers find healthy foods available in their communities. Find out more at www.WestonAPrice.org

History of Milk
History of Milk
Ancient Times
● 4000 BC - Scientists have discovered that Neolithic farmers in Britain and Northern Europe may have been among the first to begin milking cattle for human consumption.
● 3000 BC - Archaeological evidence shows that the Ancient Sumerians drank cow's milk and also made cow's milk into cheeses and butters.
● 1750 - 500 BC - The Vedic civilization that ruled Northern India relied heavily upon the cow and the dairy products that it provided.
● In the Bible - Ancient Hebrews held milk in high favor; the earliest Hebrew scriptures contain abundant evidence of the widespread use of milk from very early times. In all, the Bible contains some fifty references to milk and milk products.
History of Milk
Colonial Times in America
● 1525 - First cattle to arrive in the New World landed in Vera Cruz, Mexico. Soon afterword, some made their way across the Rio Grande to proliferate in the wild. They became known as “Texas Cattle.”
● 1610 - First cows were brought to Jamestown colony. From then on, cows were seen as a staple and sent over on almost every ship.
● 1679-1776 - Spanish missionaries introduced cattle to California and came to rely on their milk for sustenance...
– During a food shortage in 1772 - "Milk from the cows and some vegetables from the garden have been [our] chief subsistence." - Junipero Serra
● By 1790 America was exporting about 1 million pounds of butter and 100 thousand pounds of cheese each year.
History of Milk
Milk Maids and Smallpox
● In the 18th century it was common knowledge in Europe that milk maids seemed to be immune from the smallpox plagues when they swept through Europe.
– In 1796, English physician Edward Jenner developed a vaccine for smallpox based upon this.
– In the United States, compulsory smallpox vaccination was introduced on a state by state basis, beginning in the early 1800s.
History of Milk
What did all this milk have in common?
● Raw
● Grass Fed
● No Refrigeration
– Until the 1800s most milk was consumed in fermented form – clabber, yogurt, cheese, butter
– Fresh milk was only for children, farmers, and milk maids.
History of Milk
Industrial Revolution in America
● Many people left farms to settle in the cities.
● Poverty, poor sanitation, and inadequate nutrition rendered more women unable to breastfeed. Others could not breastfeed because they had to work long hours in factories.
● The population as a whole, not just children, began drinking milk as a cheap source of nutrition.
History of Milk
Swill Milk● The War of 1812 cut of America's whiskey supply from the British
West Indies and the alcohol distillery business in the United States began to grow.
● Large amounts of swill (spent-grains) were produced as a byproduct of whiskey and other alcohol production.
● Many distilleries opened dairies and began feeding their dairy cows with the waste swill.
● The low nutritional content of the swill lead to sickness in the cows and in the humans who drank their milk.
– "Confined to filthy, manure-filled pens, the unfortunate cows gave a pale, bluish milk so poor in quality, it couldn't even be used for making butter or cheese."
History of Milk
The Milk Problem● By the 1890's a growing number of influential people
throughout the country began to realize that American cities had a milk problem.
● The death rate of infants in US cities was around 50% and it was widely believed that this was due at least in part to the poor quality of milk available to the poorer people in the cities.
● No one knew what to do about it until Henry Coit and Nathan Straus came along. They each had their own suggestion as to how to fix the milk problem.
History of Milk
Certification or Pasteurization● Henry Coit, a medical doctor, was the founder of the first
Medical Milk Commission and the certified milk movement, which resulted in the availability of safe raw milk from regulated dairies for physicians, their patients and the public.
● Nathan Straus, a businessman, was the founder and subsidizer of New York City’s Milk Depots, outlets that provided pasteurized milk at low cost for the city’s poor.He became the chief advocate and spokesperson for the compulsory pasteurization of all milk.
History of Milk
Certification or Pasteurization
● Initially, from around 1890 to 1910, the movements for certified raw milk and pasteurization coexisted and in many ways even complemented one another.
● From about 1910 until the 1940s, an uneasy truce existed. Certified raw milk was available for those who wanted it, while the influence of Straus and his allies saw to it that most states and municipalities adopted regulations that required all milk other than certified milk to be pasteurized.
History of Milk
1910 New York Milk Committee Conference● Goal was to reach a consensus on how to handle the city’s dairy
products● Most participants were opposed to pasteurization and considered
certified raw milk superior.● But city officials did not think they could afford the necessary
inspection force to safeguard raw milk.● Result: the Committee endorsed pasteurization because “Private
companies, particularly larger companies, through their capital investment in pasteurizing technology, would enable the state to supply the guarantee of milk safety without imposing further public costs.
● Decision had nothing to do with science, only with fiscal expediency.
History of Milk
The Raw Milk Cure● 1929 - Dr. J.E. Crewe, MD, one of the founders of the
Mayo Clinic published an article entitledRaw Milk Cures Many Diseases
– “The patients are put at rest in bed and are given at half-hour intervals from five to ten quarts of milk a day.”
– “Very rich raw milk is used...”
– “The treatment is used in many chronic conditions but chiefly in tuberculosis, diseases of the nervous system, cardiovascular and renal conditions, hypertension, and in patients who are underweight, rundown, etc. Striking results are seen in diseases of the heart and kidneys and high blood pressure.”
History of Milk
An Era of Pasteurization● For the next several decades, outbreaks of illnesses were routinely
blamed on unpasteurized milk. How much of this was in fact caused by the milk we cannot know for sure.
● Pasteurization offered a quick fix to the problem.● Powerful commercial interests applied further pressure on politicians
and newspapers to extol the virtues of pasteurization and downplay the disadvantages.
● Other cities throughout America followed the lead of New York.– By 1917, pasteurization of all milk except that from cows proven
to be free of tuberculosis was either required or officially encouraged in 46 of the country's 52 largest cities.
– The proportion of milk pasteurized in these cities ranged from 10 percent to 97 percent; in most it was well over 50 percent.
Raw Milk Today
Nutrients inRaw Milk
Nutrients in Raw Milk
Proteins
There are several types of proteins in milk. The major milk proteins are unique to milk - not found in any other tissue
● Caseins: easily digested in the intestine and are a high quality source of amino acids. Perfect for growth and development of young mammals.
● Whey: includes a long list of enzymes, hormones, growth factors, nutrient transporters, disease resistance factors, and compounds needed for detoxification.
Nutrients in Raw Milk
Proteins● Proteins carry vitamins and minerals through the gut into the
blood stream
● They are three dimensional, like tinker toys, and very fragile.
– Pasteurization and ultra-pasteurization de-nature (flatten) the three-dimensional proteins, destroying their biological activity
– The body thinks they are foreign proteins and mounts an immune defense.
– Immune attacks lead to juvenile diabetes, asthma, allergies and other disorders later in life.
Nutrients in Raw Milk
Fats● Fats get a bad rap! New research is proving that fat is not the
enemy like we have been told for the past 20 years.
● Fats from animal sources, especially from grass-fed milk, provide a concentrated source of energy in the diet.
● Also provide the building blocks for cell membranes and a variety of hormones.
● Required for the conversion of carotene to vitamin A
● Needed for mineral absorption.
● Act as carriers for important fat-soluble vitamins A, D, E and K.
Nutrients in Raw Milk
Fats
● Conjugated Linoleic Acid (CLA) - a type of fat.
– Plays an important role in disease prevention.
– Recent studies have shown that CLA has strong anti-cancer effects and aids in weight loss.
– Milk from grass fed cows contains up to 5 times more CLA than milk from conventionally fed cows.
– Non-fat dairy products contain no CLA
Nutrients in Raw Milk
Cholesterol● Cholesterol in the cell membrane gives our cells necessary stiffness and
stability.
● Acts as a precursor to vital corticosteroids, hormones that help us deal with stress and protect against heart disease and cancer.
● Cholesterol is precursor to vitamin D, a vital fat-soluble vitamin needed for many systems in the body.
● Bile salts are made from cholesterol, vital for digestion and assimilation of dietary fats.
● Recent research shows that cholesterol acts as an antioxidant, protecting against free radical damage that leads to heart disease and cancer.
● Needed for proper function of serotonin receptors in the brain.
● Plays an important role in maintaining the health of the intestinal wall.
Nutrients in Raw Milk
Water Soluble Vitamins● Raw milk is a good source of
– thiamin (vitamin B1)
– riboflavin (vitamin B2)
– vitamin B12● Raw milk contains small amounts of
– Niacin (vitamin B3)
– pantothenic acid (vitamin B5)
– pyridoxine (vitamin B6)
– vitamin C
– folate
Nutrients in Raw Milk
Fat Soluble Vitamins● Most importantly, raw milk is an excellent source of the
fat- soluble vitamins:
– Vitamin A
– Vitamin D
– Vitamin E
– Vitamin K
– and Activator X (now believed to be vitamin K2)
● These were the nutrients Dr. Weston A. Price found to be lacking in modern society.
Nutrients in Raw Milk
Vitamin A● This all important vitamin is a catalyst on which innumerable
biochemical processes depend.● According to Dr. Price, neither protein, minerals nor water-soluble
vitamins can be utilized by the body without vitamin A.● Also acts as an antioxidant, protecting the body against pollutants and
free radicals.● Stimulates the secretion of gastric juices needed for protein digestion.● Plays a vital role in building strong bones and rich blood.● Preformed vitamin A only comes from animal sources.● Vegetables only provide a precursor to vitamin A. Many people,
particularly infants, children, diabetics, and people with poor thyroid function cannot make the conversion to useable vitamin A.
Nutrients in Raw Milk
Vitamin D● Needed for calcium and phosphorus absorption and thus is
essential for strong bones, healthy teeth and normal growth.
● Protects against cancer.
● Deficiency can cause rickets and myopia.
● Dr. Price found that healthy primitive diets were rich in vitamin D containing foods like butterfat, eggs, liver, organ meats, and seafood – 10 times more than modern foods.
● Synthetic D2 has been linked to hyperactivity, coronary heart disease and other allergic reactions.
Nutrients in Raw Milk
Vitamin E● Powerful antioxidant.
● Needed for circulation, tissue repair and healing.
● Works in concert with trace elements selenium and zinc to prevent cancer and cardiovascular disease.
Nutrients in Raw Milk
Vitamin K● Needed for blood clotting
● Plays an important role in bone formation.
● Often given to postmenopausal women to help preventbone loss.
Nutrients in Raw Milk
Activator X● Discovered by Dr. Weston A. Price
● A potent catalyst to mineral absorption.
● Only found in animal products from animals eating rapidly growing, green grass.
● Now believed to be Vitamin K2
Nutrients in Raw Milk
Enzymes● Lactase: breaks down lactose, a sugar found in milk
– Many people who do not digest pasteurized milk well are thought to be lactose intollerant. Raw milk is usually no problem for those people.
● Lactoferrin: plays many roles related to iron
– kills a wide range of iron-loving pathogens such as TB bacillus and Candida albicans
– Supports assimilation of iron in milk, thus preventing anemia.
– Strengthens the immune system and supports growth in children.
Nutrients in Raw Milk
Enzymes● Amylase: a starch splitting enzyme. All mammals secrete amylase from the salivary
glands and the pancreas, but when they consume raw milk, these glands are spared the need to do so.
● Catalase: found in almost all animal cells; converts hydrogen peroxide into water and oxygen, thus protecting the cells.
● Galactase: breaks down galactose, a sugar that plays a vital role in the development of the nervous system.
● Lactoperoxidase: derived from hemoglobin in the cows blood; acts as an antioxidant and can also destroy bad bacteria in milk.
● Lipase: a fat splitting enzyme secreted by the pancreas; when activated by the proper pH in the gut, it functions to split individual fatty acids away from triglyceride molecules.
● Phosphatase: The role of phosphatase in raw milk is unclear, but in the body it plays many roles.
Nutrients in Raw Milk
Enzymes● Pasteurization kills all enzymes.
● The test for successful pasteurization is the complete
destruction of the enzyme phosphatase.
Pasteurization
Pasteurization
• A process that slows microbial growth in food.
– It's not intended to kill all pathogenic micro-organisms in the food or liquid, but aims to reduce the number of viable pathogens so they are unlikely to cause disease.
• Three types of pasteurization used today:1. High Temperature/Short Time (HTST): 161o F for 15-20 seconds
2. Ultra-Heat Treated (UHT): 280o F for fraction of second
3. VAT Pasteurization: slowly heated to 161o F
• Both HTST and UHT involve rapid heating by forcing the milk between super heated stainless steel plates.

37
Pasteurization
Modern Milk Processing● Milk travels through miles of pipes and is transported in tankers.
Pasteurization
“I buy organic milk, isn't that better?”
● There is little difference between conventional pasteurized milk and pasteurized milk labeled “organic.”
● Unless the label says “Grass-Fed” or “Pasture Raised,” the cows are kept in confinement – tight spaces, mostly indoors,on a dirt or concrete floor.
● The cows are still fed grains, the grains are just grown organically. That may reduce pesticide levels but grains do not have all the nutrients that cows, and people, need.
● Organic dairy products are often Ultra Pasteurized forlonger shelf life.

Pasteurization - Lowered Nutrient Availability in Pasteurized Milk
Pasteurization
Increasing Health Problems in Children Linked toPasteurized Dairy
● Allergies● Asthma● Frequent Ear Infections● Gastro-Intestinal Problems● Diabetes● Auto-Immune Disease● Attention Deficit Disorder
● During a period of rapid population growth, the market for fluid pasteurized milk has declined at 1% per year for the past 20 years. Fewer and fewer consumers can tolerate pasteurized(and ultrapasteurized) milk.
Pasteurization
Pottenger's Cats● Studied hundreds of cats over the course of 10 years.
● Compared the effects of raw milk versus pasteurized milk.
● The raw milk group thrived with virtually no illness, producing generation after generation of healthy offspring.
● The other groups became diseased and eventually unable to reproduce.
– They were highly susceptible to infectious and chronic illnesses and exhibited degenerative skeletal changes.

Solution to the “Milk Problem”
The “Milk Problem” was solved by:• Outlawing inner city swill dairies• Improved hygiene• Improved water treatment• Replacement of the horse with the car• The Certified Raw Milk movement • Increased consumer access to refrigeration
…NOT by milk pasteurization laws
Pasteurization
45
Other Industrial Processes
● Milk is often thought of as a pure, whole food. What is sold in grocery stores today is actuallya heavily processed food product.
● Other industrial processes applied to milk include:
– Homogenization
– Standardization
– Vitamin Fortification
Pasteurization
46
Other Industrial Processes
● Homogenization
– The milk is forced through tiny holes to break apart the fat particles so they become more uniform and do not separate in the carton.
– Done for purely aesthetic reasons. Does not have anything to do with safety.
– These smaller, damaged fat particles oxidize faster and it is this rancid cholesterol that promotes heart disease.
Pasteurization
47
Other Industrial Processes
● Standardization
– All types of milk are processed through a centrifuge to separate it into skim milk and cream.
– The cream is then added back to the skim portion to yield the desired fat content for each product: whole milk (3.25% fat), 2%, 1%, or skim milk (< 0.1% fat).
Pasteurization
48
Other Industrial Processes
● Vitamin Fortification– Since pasteurization and standardization reduce the amount and
availability of fat soluble vitamins, the FDA requires pasteurized milk to be fortified.
– Synthetic vitamins are often used, many of which are not recognized by the human body and may even be harmful.
– These vitamins are added using a carrier consisting of any of the following: butter oil, corn oil, evaporated milk, non-fat dry milk, polysorbate 80, propylene glycol and glycerol monooleate.
– None of the carriers are required to be listed on the carton label.

Consider the calf, born in a muddy pasture, which then suckles on its mother’s often manure-covered teat. How can that calf, or any mammal survive?
Because raw milk contains multiple, natural, redundant systems of bioactive components that can reduce or eliminate populations of pathogenic bacteria.
Raw Milk Safety
Fivefold Protective System in Raw Milk
1. Destroys pathogens in the milk.
2. Stimulates the Immune system.
3. Builds healthy gut wall.
4. Prevents absorption of pathogens and toxins in the gut.
5. Ensures assimilation of all the nutrients.
51
Raw Milk Safety
Protective Components in Milk Fat
● Short and Medium Chain Fatty Acids: Disrupt cell walls of bad bacteria.
● Spingolipids: Bind to intestinal cells, prevent absorption of pathogens and toxins.
● Arachidonic acid: Helps build gut wall, skin and brain
● Fat-soluble vitamins A and D strengthen the immune system.

Built-In Protective Systems in Raw Milk: Lactoperoxidase
• Uses small amounts of H2O2 and free radicals to seek out and destroy bad bacteria1
• Found in all mammalian secretions—breast milk, tears, saliva, etc.1,2
• Other countries are looking into using lactoperoxidase instead of pasteurization to ensure safety of commercial milk as well as for preserving other foods1,2,3,4

• Plentiful in raw milk; effectiveness greatly reduced by pasteurization1
• Steals iron away from pathogens and carries it through the gut wall into the blood stream; has anti-inflammatory properties; stimulates the immune system1
• Kills wide range of pathogens including viruses; does not kill beneficial bacteria.2
• In a study involving mice bred to be susceptible to tuberculosis, treatment with lactoferrin significantly reduced the burden of tuberculosis organisms.3
• Mice injected with Candida albicans, another iron-loving organism, had increased survival time when treated with lactoferrin.4
• FDA approved for use in anti-microbial spray to combat E. coli O157:H7 contamination in meat industry!6

● Leukocytes: at all foreign bacteria, yeast and molds (phagocytosis). Destroyed at 56C and by pumping milk. Produce H2O2 to activate the lacto-peroxidase system. Produce anaerobic CO2 that blocks all aerobic microbes. Basis of immunity.
● B-lymphocytes: Kill foreign bacteria; call in other parts of the immune system1,2
● Macrophages: Engulf foreign proteins and bacteria2
● Neutrophils: Kill infected cells; mobilize other parts of the immune system1
● T-lymphocytes: Multiply if bad bacteria are present; produce immune-strengthening compounds1
● Immunoglobulins (IgM, IgA, IgG1, IgG2): Transfer of immunity from cow to calf/person in milk and especially colostrum; provides “passive immunization”2
● Antibodies: Bind to foreign microbes and prevent them from migrating outside the gut; initiate immune response.

● Organic Pastures: Since 1999, over 40 million servings of Organic Pastures raw milk, not one confirmed illness; in over 1,300 tests, not one proven illness and no pathogens found in the milk or milking area, or in any of the dairy cows being milked on the farm.
● Claravale: In Claravale Farm’s 80-year history, no consumers of their milk have ever gotten sick from milk-borne pathogens and no pathogens have ever been detected in the milk.
● Pasteurized Outbreaks: Since 1999, several pasteurized milk products recalled and one publicized outbreak of illness due to pasteurized milk during the same period, an outbreak of Campylobacter that sickened 1,300 inmates in 11 state prisons.

What should cows eat?
● The proper food for cows is green plants, especially the rapid growing green grasses in the spring and fall.
● If necessary, cows can be given dried hay in the winter when grasses are scarce.
● Some dairies give a little grain at milking time. That's ok, but should only represent a very small portion of their diet.
● AVOID large amounts of grains, especially soy and GMO

“Milk was designed by nature to be a perfect food – but in order for milk to be a perfect food, and a completely safe food, it should be produced and consumed as nature intended... from cows on pasture, with all the butterfat, and unpasteurized.”
