  • Most mainstream dietary advice recommends low-fat or non-fat dairy. But a growing number of experts argue that it’s far healthier to eat and drink whole, full-fat dairy products
  • Recent research found that those who ate eight portions of full-fat dairy products a day cut their risk of diabetes by nearly 25 percent, compared to those who ate fewer portions
  • A previous study proposed that it’s the palmitoleic acid, which occurs naturally in full-fat dairy products, that protects against insulin resistance and diabetes
  • Previous studies have also shown that consuming full-fat dairy may help reduce your risk of cancer, weight gain, and heart disease
  • Research also backs up the suggestion that butter is a health food. Fat levels in your blood are actually lower after eating a meal rich in butter than after eating one rich in olive oil, canola oil, or flaxseed oil

Most mainstream dietary advice recommends low-fat or non-fat dairy. But a growing number of experts argue that it’s far healthier to eat and drink whole dairy products, with all the fat left in.
Dairy foods contain roughly 50 to 60 percent saturated fat, and conventional thinking is that saturated fat is bad for your heart. This idea has been thoroughly refuted as false. It’s a mistaken interpretation of the science. In a 2010 analysis,1 scientists said:
“...There is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of [coronary heart disease or cardiovascular disease].”
More recently, research presented at the European Association for the Study of Diabetes (EASD) in Vienna, Austria, found that eating full-fat dairy products such as whole milk, cream, cheese, and butter, reduces your risk of developing diabetes.

Full-Fat Dairy Associated with Lower Risk of Diabetes

The study included nearly 27,000 people between the ages of 45-74 who were followed for 14 years.
As reported in The Telegraph,2 those who ate eight portions of full-fat dairy products a day cut their risk of diabetes by nearly 25 percent, compared to those who ate fewer portions. One serving counted as:
  • 200 milliliters (ml) of milk or yogurt
  • 20 grams (g) of cheese
  • 25 grams of cream
  • 7 grams of butter
Also, consuming 30 ml of cream or 180 ml of high-fat yoghurt daily reduced the risk of diabetes by 15 percent and 20 percent respectively, compared to those who ate none. According to lead author Dr. Ulrika Ericson of the Lund University Diabetes Center in Malmö, Sweden:3
“Our observations may contribute to clarifying previous findings regarding dietary fats and their food sources in relation to type 2 diabetes. 
The decreased risk at high intakes of high-fat dairy products, but not of low-fat dairy products, indicate that dairy fat, at least partly, explains observed protective associations between dairy intake and type 2 diabetes...
Our findings suggest, that in contrast to animal fats in general, fats specific to dairy products may have a role in prevention of type 2 diabetes.”
In 2010, a study published in the Annals of Internal Medicine4 proposed that it’s the palmitoleic acid, which occurs naturally in full-fat dairy products, that protects against insulin resistance and diabetes. People who consumed full-fat dairy had higher levels of trans-palmitoleate in their blood, and this translated to a two-thirds lower risk of developing type 2 diabetes compared to people with lower levels.

Other Research Showing Full-Fat Dairy Is Good for You

As I’ll discuss below, I firmly believe that pasteurized dairy products are best avoided. Unfortunately, research on raw dairy—which is always full-fat—are few and far between, so I’m going to refer to studies using pasteurized dairy for the sake of showing that the full-fat versions are the better choice.
Besides lowering your risk for diabetes, previous studies have also shown that consuming full-fat dairy may help reduce your risk of:
  • Cancer: Conjugated linoleic acid (CLA), a type of fat found naturally in cow's milk, significantly lowers the risk of cancer. In one study,5 those who ate at least four servings of high-fat dairy foods each day had a 41 percent lower risk of bowel cancer than those who ate less than one. Each increment of two servings of dairy products reduced a woman’s colon cancer risk by 13 percent.
  • Weight: Women who ate at least one serving of full-fat dairy a day gained 30 percent less weight over a nine-year period than women who ate only low-fat (or no) dairy products.6
  • Heart Disease: People who ate the most full-fat dairy were less likely to die from cardiovascular disease, according to a 16-year study7 of Australian adults.

More People Starting to Recognize That Butter Is Better

More and more people are starting to realize the fallacy of the low-fat myth. As noted by NPR,8 in 1992, 44 percent of household cooks surveyed reported being “concerned about the amount of cholesterol in their food.” Today, that number has dropped down to 27 percent.
Other countries have also switched over from margarine to butter in ever-increasing numbers. According to dairy economist Brian Gould, American butter export has grown from zero to just over 10 percent of the market since the early 2000s.
Keep in mind that butter’s nutritional value depends on how the cows are raised, as the fatty acid composition of butterfat varies according to the animal's diet. The very best-quality butter is raw (unpasteurized) from grass-pastured cows, preferably certified organic. (One option is to make your own butter9 from raw milk.)
The next best is pasteurized butter from grass-fed or pastured organic cows, followed by regular pasteurized butter common in supermarkets. Even the latter two are healthier choices by orders of magnitude than margarines or spreads. Avoid “Monsanto Butter,” made from cows fed almost entirely genetically engineered grains.7 This includes Land O’Lakes and Alta Dena.

The Many Health Benefits of Grass-Fed Butter

Other research backs up the suggestion that butter is a health food that offers both short-term and long-term benefits for your health. One study10 found that fat levels in your blood are actually lower after eating a meal rich in butter than after eating one rich in olive oil, canola oil, or flaxseed oil.
The scientists’ main explanation is that about 20 percent of butterfat consists of short- and medium-chain fatty acids, which are used right away for quick energy and therefore don’t contribute to fat levels in your blood. Other oils (canola, flax, etc.) contain only long-chain fatty acids, which are more readily stored as fat.
What this means is that a significant portion of the butter you consume is used immediately for energy—similar to a carbohydrate. But, unlike a carbohydrate, it doesn’t adversely affect your insulin and leptin levels. The primary nutrients found in butter are outlined in the table below. For more information on the health benefits of butter, take a look at this classic article by the Weston A. Price Foundation.11
Nutrients in Organic, Grass-Fed Butter
*Vitamin A in the most absorbable formLauric acidLecithin (necessary for cholesterol metabolism and nerve health)
Antioxidants*Vitamin EVitamin K2
Wulzen factor: hormone-like substance known to prevent arthritis and joint stiffness (destroyed by pasteurization)*Fatty acids, especially short- and medium-chain in the perfect omega-3 to omega-6 balance*CLA (Conjugated Linoleic Acid): anti-cancer agent, muscle builder, and immunity booster
Vitamin DMinerals, including selenium, manganese, chromium, zinc, and copperIodine in a highly absorbable form
CholesterolArachidonic Acid (AA): brain function and healthy cell membranesGlycospingolipids: fatty acids that protect against GI infections
*The highest amounts of CLA and omega-3 fats come from cows raised on grass pastures. Their butter is also 50 percent higher in vitamins A and E, and 400 percent higher in beta-carotene, giving grass-fed butter its deeper yellow color.

Raw Dairy Is Preferable Over Pasteurized

While the featured research focused on the fat content of the dairy, I also want to point out that the issue of pasteurization is another important consideration. Raw milk from organically raised grass-fed cows is far superior in terms of health benefits compared to pasteurized milk. Pasteurization destroys enzymes, diminishes vitamins, denatures milk proteins, destroys vitamin B12 and vitamin B6, kills beneficial bacteria, and actually promotes the growth of pathogens. Many of the enzymes that are destroyed in this process are needed for digestion. As a result, drinking pasteurized milk can tax your pancreas and promote disease—particularly allergies.
A number of studies have also demonstrated the superior safety of raw milk compared to pasteurized. Contrary to popular belief, the vast majority of foodborne illnesses in the US are actually linked to factory farmed and highly processed foods, not raw foods. For example, late last year Chobani Greek yoghurt was recalled following reports of gastrointestinal illness.12 The yogurt, which is pasteurized and not raw, was found to be contaminated with a fungus called Murcor circinelloides.
Unfortunately, despite overwhelming evidence of safety and health benefits, several US states have outright banned the sale of raw milk for fear of contamination. That’s in sharp contrast to Europe, where some nations even sell it in vending machines13... But there’s really no need to fret about the safety of raw milk, provided it comes from organically raised, pastured cows. Research by Dr. Ted Beals,14 MD, featured in the summer 2011 issue of Wise Traditions, shows that you are actually about 35,000 times more likely to get sick from other foods (most of which are processed) than you are from raw milk.
You can easily ascertain the quality of grass-fed milk, butter, and yoghurt by its color. The carotenoids in the plants cows eat on pasture gives grass-fed products a more yellow-orange cast. When cows are raised on dried grass or hay, opposed to fresh-growing grass, you end up with a whiter product, which is an indication of reduced carotenoid and antioxidant content. Raw milk yogurt is also very thick and creamy, compared to pasteurized commercial varieties. The same goes for pastured eggs, which can be ascertained by their deep orange yolk. CAFO chickens, which never go outdoors, and are fed grains rather than bugs and insects, produce eggs with pale yellow yolks.

Documented Raw Milk Health Benefits

Just like raw organic butter, raw milk from grass-fed cows has a number of health benefits you simply will not obtain from drinking pasteurized and homogenized CAFO milk. For example, raw milk is:
Loaded with healthy bacteria that are good for your gastrointestinal tractHigh in omega-3 and low omega-6, which is the beneficial ratio between these two essential fats
Full of more than 60 digestive enzymes, growth factors, and immunoglobulins (antibodies). These enzymes are destroyed during pasteurization, making pasteurized milk much harder to digestLoaded with vitamins (A, B, C, D, E, and K) in highly bioavailable forms, and a very balanced blend of minerals (calcium, magnesium, phosphorus, and iron) whose absorption is enhanced by liveLactobacilli
Rich in conjugated linoleic acid (CLA), which fights cancer and boosts metabolismRich in healthy unoxidized cholesterol
Rich in beneficial raw fats, amino acids, and proteins in a highly bioavailable form, all 100 percent digestibleIt also contains phosphatase, an enzyme that aids and assists in the absorption of calcium in your bones, and lipase enzyme, which helps to hydrolyze and absorb fats

Where to Find Raw Milk

There are several resources out there to help you locate raw milk and other dairy products, and the Farm to Consumer Legal Defense Fund provides a state-by-state review of raw milk laws, in case you don’t already know what your state’s rules are.
In many states, you can make a private agreement with a dairy farmer, called a herdshare, which entitle you to the benefits of owning a “share” of a cow, such as a certain amount of milk each week. If you simply cannot obtain raw milk, for whatever reason, you have a couple of options that are likely to be better than drinking conventional pasteurized and homogenized milk from confined animal feeding operations (CAFOs).
Some food US stores have started selling lightly pasteurized and non-homogenized organic milk. If your local store doesn’t carry it yet, you can ask them to do so. As a last resort, you could opt for organic pasteurized milk. At least, you’ll avoid many of the detriments of CAFO dairy that way—including antibiotics, recombinant bovine growth hormone (rBGH), and other drugs. You’ll also avoid a source of genetically engineered organisms (GMOs) and glyphosate, as CAFO cattle are typically fed genetically engineered grains.

New Raw Milk Bills Could Allow More Food Freedom

Raw milk is the only food banned in interstate commerce. This makes it challenging (though not impossible) for small farmers to share their raw milk products with people living across state lines. Such nonsensical bans have resulted in an increasing number of violent crack-downs on peaceful dairy farmers who want nothing more than to provide their customers with high-quality food.
Fortunately, there are signs of progress and glimmers of hope. A bipartisan coalition of 20 lawmakers is planning to introduce a series of “food freedom” bills this year. The first two to be released could be a major step forward in the raw milk movement. According to Congressman Thomas Massie of Kentucky, these bills are intended to improve consumer food choices while protecting local farmers from federal interference:
  • The Milk Freedom Act of 2014 (HR 4307): The bill would prohibit the federal government from interfering with the interstate traffic of raw milk products, offering relief for small farmers who have been harassed, fined, or prosecuted for distributing raw milk.
  • The Interstate Milk Freedom Act of 2014 (HR 4308): This bill would prevent the federal government from interfering with trade of unpasteurized natural milk or milk products between states where distribution or sale of such products is already legal.
To protect food freedom and freedom of choice for all Americans, I urge you to contact your government representatives, and ask them to vote YES on both HB 4307 and HB 4308. The Farm-to-Consumer Defense Fund has created a one-click form letter for this purpose. Please take a moment to sign the petition right now.

The Right Kind of Milk Can Do Your Body Good

While both the US Food and Drug Administration (FDA) and the CDC warn that raw milk can carry disease-causing bacteria, they completely overlook the fact that these bacteria are the result of industrial farming practices that lead to diseased animals, which may then in turn produce contaminated milk.
This is a key issue, as raw milk from a confined animal feeding operation (CAFO) IS dangerous and must be pasteurized in order to be fit to drink, whereas raw milk from cows raised on pasture IS NOT dangerous and does not need pasteurization. It’s really critical to understand that it is the source of the milk makes all the difference when it comes to raw milk. So, to summarize, there are two primary considerations to take into account when deciding on dairy:
  1. Full-fat versus low-fat or non-fat. The former is definitely a better choice, regardless of whether you opt for raw, organic lightly pasteurized, or organic pasteurized. Pasteurized and homogenized low fat dairy products and skim milk have little to no redeeming nutritional value, as all the good stuff has been processed into oblivion or taken out altogether
  2. Raw versus pasteurized. Pasteurization damages and denatures the milk, rendering it a source of allergies and digestive problems. Many who are lactose intolerant and cannot eat or drink dairy find that they do not have these problems with raw grass-fed dairy products.
