The Health Benefits of Raw Milk
There's
little mention in the mainstream media
these days, of traditional foods having
healing properties. Sure, there's a ton
of hype touting unfermented soy
products, vegetable oils and supplements
as modern saviors, but in reality, these
items have risk-to-benefit ratios like
many drugs do.
Few people are aware that clean, raw
milk from grass-fed cows was actually
used as a medicine in the early part of
the last century. That's right. Milk
straight from the udder, the "stem cell"
of foods, was used as medicine to treat,
and frequently cure some serious
chronic diseases. From the time of
Hippocrates to until just after World
War II, this "white blood" nourished and
healed uncounted millions.
Clean raw milk from pastured cows is a
complete and properly balanced food. You
could live on it exclusively if you had
to. Indeed, published accounts exist of
people who have done just that. What's
in it that makes it so great? Let's look
at the ingredients to see what makes it
such a powerful food.
Proteins
Our bodies use amino acids as building
blocks for protein. Depending on who you
ask, we need 20-22 of them for this
task. Eight of them are considered
essential, in that we have to get
them from our food. The remaining 12-14
we can make from the first eight in the
chemical factories of our bodies.
Raw cow's milk has all 20 of the
standard amino acids, saving our bodies
the work of having to convert any into
usable form. About 80% of the proteins
in milk are caseins- reasonably heat
stable but easy to digest. The remaining
20% or so fall into the class of whey
proteins, many of which have important
physiological effects (bioactivity).
Also easy to digest, but very heat
sensitive, these include key enzymes
(specialized proteins) and enzyme
inhibitors, immunoglobulins
(antibodies), metal-binding proteins,
vitamin binding proteins and several
growth factors.
Current research is now focusing on
fragments of protein (peptide segments)
hidden in casein molecules that exhibit
anti-microbial activity.
Lactoferrin,
an iron-binding protein, has numerous
beneficial properties including (as you
might guess) improved absorption and
assimilation of iron, anti-cancer
properties and anti-microbial action
against several species of bacteria
responsible for dental cavities. Recent
studies also reveal that it has powerful
antiviral properties as well.
Two other players in raw milk's
antibiotic protein/enzyme arsenal are
lysozyme and
lactoperoxidase. Lysozyme can
actually break apart cell walls of
certain undesirable bacteria, while
lactoperoxidase teams up with other
substances to help knock out unwanted
microbes too.
The immunoglobulins, an extremely
complex class of milk proteins also
known as antibodies, provide
resistance to many viruses, bacteria and
bacterial toxins and may help reduce the
severity of asthma symptoms. Studies
have shown significant loss of these
important disease fighters when milk is
heated to normal processing
temperatures.
Carbohydrates
Lactose, or milk sugar, is the primary
carbohydrate in cow's milk. Made from
one molecule each of the simple sugars
glucose and galactose, it's known as a
disaccharide. People with lactose
intolerance for one reason or another
(age, genetics, etc.), no longer make
the enzyme lactase and so can't digest
milk sugar. This leads to some unsavory
symptoms, which, needless to say, the
victims find rather unpleasant at best.
Raw milk, with its lactose-digesting
Lactobacilli bacteria intact, may allow
people who traditionally have avoided
milk to give it another try.
The end-result of lactose digestion is
a substance called lactic acid
(responsible for the sour taste in
fermented dairy products). Besides
having known inhibitory effects on
harmful species of bacteria, lactic acid
boosts the absorption of calcium,
phosphorus and iron, and has been shown
to make milk proteins more digestible by
knocking them out of solution as fine
curd particles.
Fats
Approximately two thirds of the fat in
milk is saturated. Good or bad for you?
Saturated fats play a number of key
roles in our bodies: from construction
of cell membranes and key hormones to
providing energy storage and padding for
delicate organs, to serving as a vehicle
for important fat-soluble vitamins (see
below).
All fats cause our stomach lining to
secrete a hormone (CCK) which, aside
from boosting production and secretion
of digestive enzymes, let's us know
we've eaten enough. With that trigger
removed, non-fat dairy products and
other fat-free foods can potentially
help contribute to over-eating.
Consider that, for thousands of years
before the introduction of the
hydrogenation process (pumping hydrogen
gas through oils to make them solids)
and the use of canola oil (from
genetically modified rapeseed), corn,
cottonseed, safflower and soy oils,
dietary fats were largely saturated and
often animal based. Healthy cultures all
over the world thrived on the use of
butter, lard, tallows, poultry fats,
fish oils, tropical oils such as coconut
and palm, and cold pressed olive oil.
Now consider that prior to 1900, very
few people died from heart disease. The
introduction of hydrogenated cottonseed
oil in 1911 (as Crisco) helped begin the
move away from healthy animal fats, and
toward the slow, downward trend in
cardiovascular health from which
millions continue to suffer today.
CLA, short for conjugated
linoleic acid and abundant in milk
from grass-fed cows, is a heavily
studied, polyunsaturated Omega-6 fatty
acid with promising health benefits. It
certainly does wonders for rodents,
judging by the hundreds of journal
articles I've come across! There's
serious money behind CLA, so it's a sure
bet there's something to it.
Among
CLA's many potential benefits: it raises
metabolic rate, helps remove abdominal
fat, boosts muscle growth, reduces
resistance to insulin, strengthens the
immune system and lowers food allergy
reactions. As luck would have it,
grass-fed raw milk has from 3-5 times
the amount found in the milk from feed
lot cows.
See my
Fat Primer for a better
understanding of saturated fats and
fatty acids and their impact on our
health.
Vitamins
Volumes have been written about the two
groups of vitamins, water and fat
soluble, and their contribution to
health. Whole raw milk has them all, and
they're completely available for your
body to use. Whether regulating your
metabolism or helping the biochemical
reactions that free energy from the food
you eat, they're all present and ready
to go to work for you.
Just to repeat, nothing needs to be
added to raw milk, especially that from
grass-fed cows, to make it whole or
better. No vitamins. No minerals. No
enriching. It's a complete food. Heated
milk must have destroyed components
added back in- especially the important
fat soluble vitamins A and D.
Minerals
Our bodies, each with a biochemistry as
unique as our fingerprints, are
incredibly complex, so discussions of
minerals, or any nutrients for that
matter, must deal with ranges rather
than specific amounts. Raw milk contains
a broad selection of completely
available minerals ranging from the
familiar calcium and phosphorus on down
to trace elements, the function of some
as yet still rather unclear.
A sampling of the health benefits of
calcium, a 'macronutrient' abundant
in raw milk includes: reduction in
cancers, particularly of the colon;
higher bone mineral density in people of
every age, lower risk of osteoporosis
and fractures in older adults; lowered
risk of kidney stones; formation of
strong teeth and reduction of dental
cavities, to name a few.
An interesting feature of minerals as
nutrients is the delicate balance they
require with other minerals to function
properly. For instance, calcium needs a
proper ratio of two other
macronutrients, phosphorus and
magnesium, to be properly utilized by
our bodies. Guess what? Nature codes for
the entire array of minerals in raw milk
to be in proper balance to one another
thus optimizing their benefit to us.
Enzymes
The 60 plus (known) fully intact and
functional enzymes in raw milk have an
amazing array of tasks to perform, each
one of them essential for one key task
or another. Some of them are native to
milk, and others come from beneficial
bacteria growing in the milk. Just
keeping track of them would require a
post-doctoral degree!
To me, the most significant health
benefit derived from food enzymes is the
burden they take off our body. When we
eat a food that contains enzymes devoted
to its own digestion, it's that much
less work for our pancreas. Given the
choice, I'll bet that busy organ would
rather occupy itself with making
metabolic enzymes, letting food digest
itself.
The amylase, bacterially-produced
lactase, lipase and phosphatase in raw
milk, break down starch, lactose (milk
sugar), fat (triglycerides) and
phosphate compounds respectively, making
milk more digestible and freeing up key
minerals. Other enzymes, like catalase,
lysozyme and lactoperoxidase help to
protect milk from unwanted bacterial
infection, making it safer for us to
drink.
Cholesterol
Milk contains about 3mg of cholesterol
per gram - a decent amount. Our bodies
make most of what we need, that amount
fluctuating by what we get from our
food. Eat more, make less. Either way,
we need it. Why not let raw milk be one
source?
Cholesterol is a protective/repair
substance. A waxy plant steroid (often
lumped in with the fats), our body uses
it as a form of water-proofing, and as a
building block for a number of key
hormones.
It's natural, normal and essential to
find it in our brain, liver, nerves,
blood, bile, indeed, every cell
membrane. The best analogy I've heard
regarding cholesterol's supposed
causative effects on the clogging of our
arteries is that blaming it is like
blaming crime on the police because
they're always at the scene.
Seriously consider educating yourself
fully on this critical food issue. It
could, quite literally, save your life.
See my Cholesterol Primer (also still
under construction) to learn the truth.
Beneficial
Bacteria
Through the process of fermentation,
several strains of bacteria naturally
present or added later (Lactobacillus,
Leuconostoc and Pediococcus,
to name a few) can transform milk into
an even more digestible food.
With high levels of lactic acid,
numerous enzymes and increased vitamin
content, 'soured' or fermented dairy
products like yogurt and
kefir (made with bacteria and
yeast, actually) provide a plethora
of health benefits for the savvy people
who eat them. Being acid lovers, these
helpful little critters make it safely
through the stomach's acid environment
to reach the intestines where they
really begin to work their magic (Above
right, Lactobacillus casei).
Down there in the pitch black, some of
them make enzymes that help break
proteins apart- a real benefit for
people with weakened digestion whether
it be from age, pharmaceutical
side-effects or illness.
Other strains get to work on fats by
making lipases that chop triglycerides
into useable chunks. Still others take
on the milk sugar, lactose, and, using
fancy sounding enzymes like
beta-galactosidase, glycolase and lactic
dehydrogenase (take notes, there'll be a
quiz later!), make lactic acid out of
it.
As I mentioned way up yonder in the
Carbohydrate section, having lactic acid
working for you in your nether regions
can be a good thing. Remember? It boosts
absorption of calcium, iron and
phosphorus, breaks up casein into
smaller chunks and helps eliminate bad
bugs. (I told you there'd be a quiz!)
Raw milk is a living food with
remarkable self-protective properties,
but here's the kick: most foods tend to
go south as they age, raw milk just
keeps getting better.
Not to keep harping on this, but what
the heck: through helpful bacterial
fermentation, you can expect an increase
in enzymes, vitamins, mineral
availability and overall digestibility.
Not bad for old age!
A Word About Diet In General
Use common sense and stick with whole,
unprocessed foods, free from genetic
tweaking (there's still just too much
conflicting information out there on
that topic), and you'll likely be ahead
of the game.
Cook your foods minimally, and you'll
be even better off. Learn about
sprouting and fermentation. Question
everything before letting it past your
lips.
Explore what worked for countless
generations before ours, and put it to
work for yourself today. You can
achieve great health by diet alone. I've
done it, and so can you!
