The Diet Dictocrats have succeeded in convincing Americans that butter
is dangerous, when in fact it is a valued component of many traditional
diets and a source of the following nutrients:
Fat-Soluble Vitamins: These include
true vitamin A or retinol, vitamin D, vitamin K and vitamin E as well
as all their naturally occurring cofactors needed to obtain maximum
effect. Butter is America's best source of these important nutrients.
In fact, vitamin A is more easily absorbed and utilized from butter
than from other sources.61 Fortunately, these fat-soluble vitamins
are relatively stable and survive the pasteurization process.
When Dr. Weston Price studied isolated traditional peoples around
the world, he found that butter was a staple in many native diets.
(He did not find any isolated peoples who consumed polyunsaturated
oils.) The groups he studied particularly valued the deep yellow butter
produced by cows feeding on rapidly growing green grass. Their natural
intuition told them that its life-giving qualities were especially
beneficial for children and expectant mothers.
When Dr. Price analyzed this deep yellow butter he found that it
was exceptionally high in all fat-soluble vitamins, particularly vitamin
A. He called these vitamins "catalysts" or "activators."
Without them, according to Dr. Price, we are not able to utilize the
minerals we ingest, no matter how abundant they may be in our diets.
He also believed the fat-soluble vitamins to be necessary for absorption
of the water-soluble vitamins.
Vitamins A and D are essential for growth, for healthy bones, for
proper development of the brain and nervous systems and for normal
sexual development. Many studies have shown the importance of butterfat
for reproduction; its absence results in "nutritional castration,"
the failure to bring out male and female sexual characteristics. As
butter consumption in America has declined, sterility rates and problems
with sexual development have increased. In calves, butter substitutes
are unable to promote growth or sustain reproduction.62
Not all the societies Dr. Price studied ate butter; but all the groups
he observed went to great lengths to obtain foods high in fat-soluble
vitamins-fish, shellfish, fish eggs, organ meats, blubber of sea animals
and insects. Without knowing the names of the vitamins contained in
these foods, isolated traditional societies recognized their importance
in the diet and liberally ate the animal products containing them.
They rightly believed such foods to be necessary for fertility and
the optimum development of children.
Dr. Price analyzed the nutrient content of native diets and found
that they consistently provided about ten times more fat-soluble vitamins
than the American diet of the 1930's. This ratio is probably more
extreme today as Americans have deliberately reduced animal fat consumption.
Dr. Price realized that these fat-soluble vitamins promoted the beautiful
bone structure, wide palate, flawless uncrowded teeth and handsome,
well-proportioned faces that characterized members of isolated traditional
groups.
American children in general do not eat fish or organ meats, at least
not to any great extent, and blubber and insects are not a part of
the western diet; many will not eat eggs. The only good source of
fat-soluble vitamins in the American diet, one sure to be eaten, is
butterfat. Butter added to vegetables and spread on bread, and cream
added to soups and sauces, ensure proper assimilation of the minerals
and water-soluble vitamins in vegetables, grains and meat.
The Wulzen Factor: Called the
"antistiffness" factor, this compound is present in raw
animal fat. Researcher Rosalind Wulzen discovered that this substance
protects humans and animals from calcification of the joints-degenerative
arthritis.
It also protects against hardening of the arteries, cataracts and
calcification of the pineal gland.63 Calves fed pasteurized milk or
skim milk develop joint stiffness and do not thrive. Their symptoms
are reversed when raw butterfat is added to the diet. Pasteurization
destroys the Wulzen factor-it is present only in raw butter, cream
and whole milk.
The Price Factor or Activator X:
Discovered by Dr. Price, Activator X is a powerful catalyst which,
like vitamins A and D, helps the body absorb and utilize minerals.
It is found in organ meats from grazing animals and some sea food.
Butter can be an especially rich source of Activator X when it comes
from cows eating rapidly growing grass in the spring and fall seasons.
It disappears in cows fed cottonseed meal or high protein soy-based
feeds.64 Fortunately, Activator X is not destroyed by pasteurization.
Arachidonic Acid: A 20-carbon
polyunsaturate containing four double bonds, found in small amounts
only in animal fats. Arachidonic acid (AA) plays a role in the function
of the brain, is a vital component of the cell membranes and is a
precursor to important prostaglandins. Some dietary gurus warn against
eating foods rich in AA, claiming that it contributes to the production
of "bad" prostaglandins, ones that cause inflammation. But
prostaglandins that counteract inflammation are also made from AA.
Short- and Medium-Chain Fatty Acids:
Butter contains about 12-15% short- and medium-chain fatty acids.
This type of saturated fat does not need to be emulsified by bile
salts but is absorbed directly from the small intestine to the liver,
where it is converted into quick energy. These fatty acids also have
antimicrobial, antitumor and immune-system-supporting properties,
especially 12-carbon lauric acid, a medium-chain fatty acid not found
in other animal fats.
Highly protective lauric acid should be called a conditionally essential
fatty acid because it is made only by the mammary gland and not in
the liver like other saturated fats.65 We must obtain it from one
of two dietary sources-small amounts in butterfat or large amounts
in coconut oil. Four-carbon butyric acid is all but unique to butter.
It has antifungal properties as well as antitumor effects.66
Omega-6 and Omega-3 Essential Fatty Acids:
These occur in butter in small but nearly equal amounts. This excellent
balance between linoleic and linolenic acid prevents the kind of problems
associated with overconsumption of omega-6 fatty acids.
Conjugated Linoleic Acid: Butter
from pasture-fed cows also contains a form of rearranged linoleic
acid called CLA, which has strong anticancer properties. It also encourages
the buildup of muscle and prevents weight gain. CLA disappears when
cows are fed dry hay or processed feed.67
Lecithin: Lecithin is a natural
component of butter that assists in the proper assimilation and metabolization
of cholesterol and other fat constituents.
Cholesterol: Mother's milk is
high in cholesterol because it is essential for growth and development.
Cholesterol is also needed to produce a variety of steroids that protect
against cancer, heart disease and mental illness.
Glycosphingolipids: This type
of fat protects against gastrointestinal infections, especially in
the very young and the elderly. For this reason, children who drink
skimmed milk have diarrhea at rates three to five times greater than
children who drink whole milk.68
Trace Minerals: Many trace minerals
are incorporated into the fat globule membrane of butterfat, including
manganese, zinc, chromium and iodine. In mountainous areas far from
the sea, iodine in butter protects against goiter. Butter is extremely
rich in selenium, a trace mineral with antioxidant properties, containing
more per gram than herring or wheat germ.
One frequently voiced objection to the consumption of butter and
other animal fats is that they tend to accumulate environmental poisons.
Fat-soluble poisons such as DDT do accumulate in fats; but water-soluble
poisons, such as antibiotics and growth hormones, accumulate in the
water fraction of milk and meats.
Vegetables and grains also accumulate poisons. The average plant
crop receives ten applications of pesticides-from planting to storage-while
cows generally graze on pasture that is unsprayed. Aflatoxin, a fungus
that grows on grain, is one of the most powerful carcinogens known.
It is correct to assume that all of our foods, whether of vegetable
or animal origin, may be contaminated. The solution to environmental
poisons is not to eliminate animal fats-so essential to growth, reproduction
and overall health-but to seek out organic meats and butter from pasture-fed
cows, as well as organic vegetables and grains. These are becoming
increasingly available in health food stores and supermarkets and
through mail order and cooperatives.
Composition Of Different Fats
Before leaving this complex but vital subject of fats, it is worthwhile
examining the composition of vegetable oils and other animal fats
in order to determine their usefulness and appropriateness in food
preparation:
Duck and Goose Fat are semisolid
at room temperature, containing about 35% saturated fat, 52% monounsaturated
fat (including small amounts of antimicrobial palmitoleic acid) and
about 13% polyunsaturated fat. The proportion of omega-6 to omega-3
fatty acids depends on what the birds have eaten. Duck and goose fat
are quite stable and are highly prized in Europe for frying potatoes.
Chicken Fat is about 31% saturated,
49% monounsaturated (including moderate amounts of antimicrobial palmitoleic
acid) and 20% polyunsaturated, most of which is omega-6 linoleic acid,
although the amount of omega-3 can be raised by feeding chickens flax
or fish meal, or allowing them to range free and eat insects. Although
widely used for frying in kosher kitchens, it is inferior to duck
and goose fat, which were traditionally preferred to chicken fat in
Jewish cooking.
Lard or pork fat is about 40%
saturated, 48% monounsaturated (including small amounts of antimicrobial
palmitoleic acid) and 12% polyunsaturated. Like the fat of birds,
the amount of omega-6 and omega-3 fatty acids will vary in lard according
to what has been fed to the pigs. In the tropics, lard may also be
a source of lauric acid if the pigs have eaten coconuts.
Like duck and goose fat, lard is stable and a preferred fat for frying.
It was widely used in America at the turn of the century. It is a
good source of vitamin D, especially in third-world countries where
other animal foods are likely to be expensive. Some researchers believe
that pork products should be avoided because they may contribute to
cancer. Others suggest that only pork meat presents a problem and
that pig fat in the form of lard is safe and healthy.
Beef and Mutton Tallows are 50-55%
saturated, about 40% monounsaturated and contain small amounts of
the polyunsaturates, usually less than 3%. Suet, which is the fat
from the cavity of the animal, is 70-80% saturated. Suet and tallow
are very stable fats and can be used for frying. Traditional cultures
valued these fats for their health benefits. They are a good source
of antimicrobial palmitoleic acid.
Olive Oil contains 75% oleic
acid, the stable monounsaturated fat, along with 13% saturated fat,
10% omega-6 linoleic acid and 2% omega-3 linolenic acid. The high
percentage of oleic acid makes olive oil ideal for salads and for
cooking at moderate temperatures. Extra virgin olive oil is also rich
in antioxidants.
It should be cloudy, indicating that it has not been filtered, and
have a golden yellow color, indicating that it is made from fully
ripened olives. Olive oil has withstood the test of time; it is the
safest vegetable oil you can use, but don't overdo. The longer chain
fatty acids found in olive oil are more likely to contribute to the
buildup of body fat than the short- and medium-chain fatty acids found
in butter, coconut oil or palm kernel oil.
Peanut Oil contains 48% oleic
acid, 18% saturated fat and 34% omega-6 linoleic acid. Like olive
oil, peanut oil is relatively stable and, therefore, appropriate for
stir-frys on occasion. But the high percentage of omega-6 presents
a potential danger, so use of peanut oil
should be strictly limited.
Sesame Oil contains 42% oleic
acid, 15% saturated fat, and 43% omega-6 linoleic acid. Sesame oil
is similar in composition to peanut oil. It can be used for frying
because it contains unique antioxidants that are not destroyed by
heat.
However, the high percentage of omega-6 militates against its use.
Safflower, Corn, Sunflower, Soybean and
Cottonseed Oils all contain over 50% omega-6 and, except
for soybean oil, only minimal amounts of
omega-3. Safflower oil contains almost 80% omega-6. Researchers
are just beginning to discover the dangers of excess omega-6 oils
in the diet, whether rancid or not. Use of
these oils should be strictly avoided.
They should never be consumed after they have been heated, as in
cooking, frying or baking. High oleic safflower and sunflower oils,
produced from hybrid plants, have a composition similar to olive oil,
namely, high amounts of oleic acid and only small amounts of polyunsaturated
fatty acids and, thus, are more stable than traditional varieties.
However, it is difficult to find truly cold-pressed versions of these
oils.
Note: The bolded blue are Dr. Mercola's edited version of the original.
Canola Oil contains 5% saturated
fat, 57% oleic acid, 23% omega-6 and 10%-15% omega-3. The newest oil
on the market, canola oil was developed from the rape seed, a member
of the mustard family. Rape seed is unsuited to human consumption
because it contains a very-long-chain fatty acid called erucic acid,
which under some circumstances is associated with fibrotic heart lesions.
Canola oil was bred to contain little if any erucic acid and has
drawn the attention of nutritionists because of its high oleic acid
content. But there are some indications that canola oil presents dangers
of its own.
It has a high sulphur content and goes rancid easily. Baked goods
made with canola oil develop mold very quickly. During the deodorizing
process, the omega-3 fatty acids of processed canola oil are transformed
into trans fatty acids, similar to those in margarine and possibly
more dangerous.69 A recent study indicates that "heart healthy"
canola oil actually creates a deficiency of vitamin E, a vitamin required
for a healthy cardiovascular system.70 Other studies indicate that
even low-erucic-acid canola oil causes heart lesions, particularly
when the diet is low in saturated fat.71
For further information please see Sally
and Dr. Enig's newer article on canola oil.
Flax Seed Oil contains 9% saturated
fatty acids, 18% oleic acid, 16% omega-6 and 57% omega-3. With its
extremely high omega-3 content, flax seed oil provides a remedy for
the omega-6/omega-3 imbalance so prevalent in America today. Not surprisingly,
Scandinavian folklore values flax seed oil as a health food.
New extraction and bottling methods have minimized rancidity problems.
It should always be kept refrigerated, never heated, and consumed
in small amounts in salad dressings and spreads. Tropical
Oils are more saturated than other vegetable oils. Palm
oil is about 50% saturated, with 41% oleic acid and about 9% linoleic
acid. Coconut oil is 92% saturated with over two-thirds of the saturated
fat in the form of medium-chain fatty acids (often called medium-chain
triglycerides).
Of particular interest is lauric acid, found in large quantities
in both coconut oil and in mother's milk. This fatty acid has strong
antifungal and antimicrobial properties.
Coconut oil protects tropical populations from bacteria and fungus
so prevalent in their food supply; as third-world nations in tropical
areas have switched to polyunsaturated vegetable oils, the incidence
of intestinal disorders and immune deficiency diseases has increased
dramatically. Because coconut oil contains lauric acid, it is often
used in baby formulas. Palm kernel oil, used primarily in candy coatings,
also contains high levels of lauric acid.
These oils are extremely stable and can be kept at room temperature
for many months without becoming rancid. Highly saturated tropical
oils do not contribute to heart disease but have nourished healthy
populations for millennia.72
It is a shame we do not use these oils for cooking and baking-the
bad rap they have received is the result of intense lobbying by the
domestic vegetable oil industry.73 Red palm oil has a strong taste
that most will find disagreeable-although it is used extensively throughout
Africa-but clarified palm oil, which is tasteless and white in color,
was formerly used as shortening and in the production of commercial
French fries, while coconut oil was used in cookies, crackers and
pastries. The saturated fat scare has forced manufacturers to abandon
these safe and healthy oils in favor of hydrogenated soybean, corn,
canola and cottonseed oils.
In summary, our choice of fats and oils is one of extreme importance.
Most people, especially infants and growing children, benefit from
more fat in the diet rather than less. But the fats we eat must be
chosen with care. Avoid all processed foods containing newfangled
hydrogenated fats and polyunsaturated oils.
Instead, use traditional vegetable oils like extra virgin olive oil
and small amounts of unrefined flax seed oil. Acquaint yourself with
the merits of coconut oil for baking and with animal fats for occasional
frying. Eat egg yolks and other animal fats with the proteins to which
they are attached. And, finally, use as much good quality butter as
you like, with the happy assurance that it is a wholesome-indeed,
an essential-food for you and your whole family.
Organic butter, extra virgin olive oil, and expeller-expressed flax
oil in opaque containers are available in health food stores and gourmet
markets. Edible coconut oil can be found in Indian or Caribbean markets.
