-
- Our bodies' homeostasis, its normal biochemical processes
and immune system functioning, have been disturbed by one particular culprit
that almost no one suspects, yet whom we may "break bread" with
every day. To most folks in this weight-conscious, image-conscious, youth-conscious
culture, the words FATS and OILS (oils being merely the liquid form of
fats) are literally four-letter words. Seldom is the concept considered
that certain types of these calorie-laden foods are not only healthful,
but absolutely mandatory, for a so-to-speak "well-oiled" and
properly running human machine. The truth is, if the consumption of all
truly bad fats was eliminated from our cuisine, we would invariably have
little or none of the obesity that now permeates at least half of the American
adult population (and epidemic among our offspring as well).
-
- Doctors and scientists such as Udo Erasmus, Dr. John
McDougall, and Dr. Neil Barnard are becoming increasingly more informed,
aware, and vocal about the detrimental and beneficial characteristics of
the different fats and oils. John Finnegan, a Naturopathic Practitioner,
Nutritional Counselor, and author of THE FACTS ABOUT FATS, spoke with me
about his many years of investigation into this subject at January's National
Health Federation's 1997 Natural Health Show at the Pasadena Center. His
comments and experience are central to this article, and I am most grateful.
-
- THE MANY FACES OF FATS
-
- First, let's first get a basic understanding of the various
forms of fats, which are neatly laid out in the McDOUGALL PROGRAM FOR A
HEALTHY HEART (1996). They can be divided into three main groups: 1) SATURATED:
Contained in animal foods and a few vegetables, these fat molecules are
completely stuffed or saturated with Hydrogen, which makes it more dense.
Butter and Lard are saturated fats, and therefore solid at room temperature.
Coconut and some tropical oils also fall into this category. 2) POLYUNSATURATED:
Found in vegetables, vegetable oils, and cold-water fish. Safflower, canola,
corn, and sesame are a few examples. 3) MONOUNSATURATED: Found mostly in
Olive Oil. The healthiest fat.
-
- Although Poly- and Mono- Unsaturated fats are composed
of the same elements--CARBON, OXYGEN, and HYDROGEN--they do not have as
many Hydrogen atoms packed into the molecules as Saturated fats, and consequently
are liquid at room temperature. Dr. John McDougall stresses that these
are safe to eat, "as long as you get them as part of the grains and
vegetables you eat. However, once these fats are separated from their food
sources and used as oils, they have many negative side effects." In
other words, when the processing begins, the problems begin. "Some
food manufacturers turn (polyunsaturated) oils into saturated fats by adding
more Hydrogen to the fat molecules. This is how they turn corn oil into
margarine."
-
- Oils can be adulterated through the application of other
modern refinement techniques as well: In preparing the seeds, extracting
the oil, bleaching and deodorizing it, irreversible damage is done. Ironically,
many natural substances important to human health are either destroyed
or transformed. Researcher John Finnegan is on a mission to educate people
about these detrimental changes: "The healthy fats (essential fatty
acids) in oils are converted by heat, light, oxygen, and chemical processing
into poisonous compounds called 'trans-fats.' There has been a substantial
amount of very reputable scientific and medical research showing that trans-fats
are a major cause of cancer, heart disease, immune system breakdown, Alzeheimer's,
obesity...Many of these diseases hardly existed, or didn't exist at all,
100 years ago, and there has been a direct correlation between their rise
in development and the increased consumption of refined oils."
-
- A CALL TO ACTION
-
- Times have changed, it's true, especially when you glance
over the medical landscape. One hundred years ago, heart disease was a
virtually non-existent condition, the first recorded case of coronary occlusion
appearing in the medical literature in 1910. Deaths from cardiovascular
diseases at that time accounted for only 15% of deaths from all causes.
Today, it kills 44% of the population, an increase of almost 300% in just
90 years, despite all of our amazing technological advances. In the year
1900, cancers killed a mere 3% of the population in Europe and the U.S.
Today, it kills 23% of us, afflicts 1 in 3 (up from 1 in 10, ten years
ago), and its incidence is rising. This is an increase of over 600% in
90 years. At the beginning of the century, Alzheimer's Disease was nowhere
to be found; today, it holds the title of fourth leading cause of death.
And diabetes at that time afflicted only one person in 100,000, while today
the figure is at 1 in 20...and growing. These are the greatest killers
in affluent nations, and it's obvious to everyone that they--along with
other epidemic conditions of fatty degeneration (multiple sclerosis, kidney
and liver malfunction, osteoporosis) have increased dramatically in recent
decades. These shocking and powerful statistics are a red flag that something
has gone seriously awry, and should act as our call to action to institute
major dietary and lifestyle changes. While virulent foodborne pathogens,
bacteria, and organisms (E.Coli, listeria, salmonella, and the prion causing
Mad Cow Disease) are experiencing a resurgence, the majority of fatal diseases
attacking modern man are the result of poor eating habits, as well as dangerous
agricultural and food processing practices.
-
- WHEN OIL WAS A PRESSING MATTER
-
- Gradual, almost imperceptible, changes in the our food
supply have crept upon us over the years since the industrial revolution,
resulting in major nutritional deficits that have waged war on our health.
Tradition- ally in Europe, oil pressing was a cottage industry and these
products were sold door to door like milk and eggs. People learned from
experience that the best cooking oils, unprotected from light and air,
turned bad within a few days. A staple in many homes, unrefined fresh oils
(such as flax) were delivered once a week in small quantities and used
quickly before they spoiled. Identifiable by their seed-specific characteristic
odors and flavors, they were light and easy to digest, and sustained health
due to the therapeutic value of the nutrients they contained. More than
half a century ago, without the benefit of scientific inquiry, it was well
known that the most easily destroyed oils were also the most valuable.
-
- John Finnegan looks grimly upon our changes in attitude.
"What has happened in this country is that people's basic gut experience
and understanding of food has become really deranged. If you look at native
cultures, there is a reverence for food, an understanding that it has life.
But Americans have gotten used to food that's no longer really food. We
see it as this lifeless substance, something to just cram into our bodies
while we're on the fly pursuing more interesting and exciting things. The
quicker it can be, the better: take it out of the freezer, pop it into
the microwave. There's something that has been forgotten." And then
there are some things that were never even dreamed of...till 'round the
turn of the century, that is, when the Industrial Revolution dropped on
us like a nuclear bomb, splattering the simplicity of our pre-Twentieth
Century lives and creating a still-accelerating shock wave that rolled
through the food industry.
-
- In the 1920's, the "bigger is better" philosophy
invaded the oil trade, and huge factories were constructed where monstrous
continuous-feed, screw-type (expeller), heat-producing presses were built
to replace the small, slow, cold temperature batch presses used prior to
that time. Running round the clock, automation made their operation highly
efficient and cut down on labor costs. Needless to say, mass production
lines and high-powered, cleverly deceptive mass media advertising campaigns
elbowed out any of the remaining small companies, which were unable to
compete. By the end of the second world war, the most highly nutritious
flax oils had virtually disappeared from the market, replaced by more stable,
nutritionally-inferior oils that could withstand transport and storage
without spoiling.
-
- THE BIGGER THE FRONT, THE BIGGER THE BACK
-
- This common Japanese saying is used often to explain
what may be hidden behind many an attractive, seemingly benevolent facade.
When it comes to commercial oil manufacturers, a whole lot of dirty business
lurks in the shadows, and for most consumers, a couple of American cliches
apply here: "Ignorance is bliss" (especially where decadently
delicious food is concerned) and "Out of sight, out of mind"
(too bad we don't wear our greasy, yellow, fat-laden arteries on the outside
of our bodies).
-
- Finnegan emphasizes, "The thing to understand is
that all the oils in the supermarket, except for 'extra virgin olive oil,'
are refined." What about all those new, healthier products now being
sold in natural food stores and co-ops?, I asked. Most health-conscious
people I know are using those instead. "Now this to me is the biggest
fraud in the health food industry. All these health food oils, except for
the ones made by Omega Nutrition and Flora and Arrowhead Mills, are refined...not
as bad as the oils in the supermarkets, but they are still refined. They
are processed by what is called 'expeller pressing.' They claim they don't
heat their oils, but the problem is that when the press grinds the seed
and extracts it, heat is generated by the press, and that heat has been
measured to be between 300-500 degrees Fahrenheit. There have been an enormous
number of research studies that have shown these oils are full of trans-fats.
These health food oils are seriously misrepresented." I inquired further
about those new-fangled margarines adorning the tables of some close friends.
"They say 'no hydrogenated oils' and that's true, but those health
food store margarines are made from refined oils, which are 25-40% trans-fats.
So when they claim on the label 'contains no trans-fats,' that is a total
lie. It is an enormous crime."
-
- THE GREAT MARGARINE EXPERIMENT
-
- Margarine: "A lifeless poison, packed with carcinogens,
fit only for lubricating the front wheel bearings of your car." (From
"FACTS ABOUT FATS".) Finnegan proceeded to tell me the story
about Fred Rohe and his infamous margarine experiment. Rohe was one of
the grandfathers of the natural foods industry and owned a couple of the
earliest health food stores in San Francisco and Palo Alto, California
between 1965 and 1973. After being informed by a food technologist that,
when observed under a microscope, a hydrogenated fat molecule looked similar
to a plastic molecule, Rohe pondered "Well, if it looks a lot like
plastic, isn't it, in fact, a lot like plastic?" "Yes,"
was the answer, "lipid chemists actually talk about plasticizing oils."
Suddenly, the entrepreneur questioned if it was an ethical practice to
sell margarine to his customers, who assumed it was a healthy option. And
so the experiment was initiated to determine the answer. He placed a cube
of margarine on a saucer and placed it on a windowsill at the back of his
store, where it remained for 2 years, without decay. "I reasoned that
if I made it readily available, and if it was real food, insects and microorganisms
would invite themselves to the feast...In all that time, nobody ever saw
an insect of any description go near it. Not one speck of mold ever grew
on it." Fred Rohe came to the conclusion that "margarine really
is not food, that it's really a form of 'edible plastic.'" Needless
to say, it was removed from his shelves. Finnegan kids, "Here we've
got the perfect food, just what the pharmaceutical industry is looking
for! The premiere anti-biotic, anti-
-
- fungal, anti-viral food. This stuff is impervious. If
nothing will utilize it, that says something."
-
- CANCER: A DISEASE OF CIVILIZATION
-
- This is the title of a book by William Stephenson, a
researcher who lived with Indians in Northern Canada and Eskimos for 30
years. Westin Price, as well, spent 2-3 decades at the beginning of this
century travel- ling and living with different cultures all over the world.
According to Finnegan, "These researchers found a zero incidence of
cancer in native populations that lived on healthy diets. As soon as the
white man came and introduced processed foods, they started developing
cancer. If they returned to the traditional tribal eating habits, the cancer
would go away." As a naturopath, he is faced with this disease on
a regular basis. "I have so many young women, young vegetarian ladies,
who come to me with cancer, breast cancer, so many. Where are they getting
it from? They're getting it for several reasons: One of them is that they
use all these health food oils. Another is that they are starving for good
quality protein and fat. And another is that the enormous amount of pesticides
and plastics that we consume or are exposed to in our water supply and
food and everything else are causing havoc."
-
- FILL 'ER UP...WITH TRANS-FATS
-
- In his book, he chronicles the twice-awarded Nobel prize-winning
Doctor Warburg, conducted a famous (and often duplicated) study in which
healthy human cells were demonstrated to turn cancerous simply by depriving
them of oxygen. "From one perspective, cancer cells are simply undeveloped
cells that use an anaerobic respiration process instead of an aerobic respiration
process." Apparently, this is triggered by an absence of essential
nutrients and other key ingredients used in the building of cell membranes.
Finnegan explains that "The average consumer uses four gallons a year
of refined oils, 25-50% of which are trans-fats. So you figure that you,
as a human being, are taking into your body 1-2 gallons a year of an extremely
toxic chemical. These trans-fats are plasticized by the processing so they
are chemically inert; they don't have the biological properties of healthy
fats. They don't transport oxygen. Fats are incorporated into the cellular
membranes, where their major function is to transport oxygen from the bloodstream
into the cell, and then to transport waste products out of the cell back
into the bloodstream. So it's like the walls of your cells are built from
these compounds that are dead, and your cells cannot get the oxygen. If
these fats, as part of your energy-producing cycles, are malfunctioning,
then all your (biochemical) processes are going to be deranged. There are
so many things that start to break down."
-
- So, it turns out, the key to abundant health may not
be a matter of transforming the population into a bunch of "Jack Sprats,
who ate no fat," but rather of educating ourselves to discriminate
between wholesome, life-supporting foods and those processed pseudo-foods
whose vital forces have been tampered with. Next month, Part 2 of this
article will further detail hydrogenation of oils, essential fatty acids
vs. trans-fatty acids, and how we can protect ourselves from unconsciously
devouring those insidious "fats from hell." In the meantime,

- Last month, Part One of this article discussed the history
of food oil processing, the varieties and properties of naturally-occurring
fats, and the false claims made about supposedly "healthy" margerines
and bottled cooking oils. In this sequel, Part Two delves deeper into the
details and technicalities of the nutritional depletion associated with
them, the differences between essential fatty acids vs. trans-fatty acids,
and the hazards of hydrogenation. Before continuing, however, and while
ignorance is still bliss, you may want to enjoy one last poignant look
within the bowels of your refrigerator or kitchen pantry, because the edible
inhabitants dwelling within may never again be viewed with quite the same
delicious fervor once the truth be known.

- FOOD: IS IT LIVE OR IS IT MEMOREX?
-
- The shelves of today's football field-sized supermarkets
are stocked (as a lake is with fish) not so much with food,
-
- FOOD: (fud) n 1. material taken into an organism and
used for growth, repair, and vital processes and as a source of energy;
2. something that nourishes, sustains, or supplies;
-
- (Merriam-Webster Dictionary)
-
- as with chemically-endowed, artifically colored and flavored,
manufactured concoctions that more resemble "soylent green" (flashback
to this sci-fi flick of the 1960's) than anything you'd imagine the Earth
would take pride in giving birth to. (I'm not insinuating that markets
don't often have extensive produce sections...but the majority of even
these raw, live foods are non-organic, minerally-depleted, and sprayed
with pesticides.) The reigning joke amongst whole food advocates is that
it just may be more nutritious to eat the paper boxes containing these
pseudo-foods than it is to eat the contents. High in fiber, low in fat
and calories, no cholesterol-hormones-steroids...after all, rats will munch
through any nice serving of cardboard, and what's good for rats is good
for us humans, right? (just ask any scientist performing vivisection experiments
in the name of medical research). However, if you happen to purchase packaged
convenience foods more for their ability to quench your appetite than to
furnish bedding material for your nest (this proves we differ from rats),
then you ought to at least be aware that most of these overprocessed laboratory
experiments just barely fall into the category of "FOOD" (per
above definition). At best, refined oils, sugars, and flours--the mainstay
ingredients of most factory-formed foodstuffs (factory-farmed animal products
are a whole other article)--may supply only a poor, inefficient energy
source, with little else merit except the decadent satisfaction of spreading
empty calories across one's tastebuds. Should any nutritive value manage
to slip through the excruciating manufacturing torture chamber (which no
decent vitamin, mineral, or protein should have to endure), it serves only
to counteract the damage done by the remainder of the product. HEALTH:
MORE THAN JUST NOT BEING SICK
-
- Now that we've officially chronicled the definition of
"food," let's get a handle on this thing called "health."
According to the World Health Organization (WHO), it is "a state of
complete physical, mental, and social well-being and not merely an absence
of disease or infirmity." In other words, just because we're devoid
of the sniffles, the flu, or the clap doesn't necessarily mean we're not
slowly sinking into some invisible pool of quicksand long before the clammy,
suffocating reality sets in. In his book "FATS THAT HEAL, FATS THAT
KILL" (1993, ALIVE BOOKS... absolutely recommended reading), renowned
nutritional expert Udo Erasmus remembers overhearing a conversation as
a teenager whereby it was proclaimed that cancer was incurable. Outraged
at the idea, he protested, "That's impossible. If you know what it
is, and you examine what you did to get it, and you know what health is,
then you should be able to reverse it by changing what you do!" Even
at that young age, he intuitively realized that "Self-healing is not
a difficult concept! Our body heals bruises, scratches, cuts, wounds, burns,
and broken bones quite masterfully." So why not cancer? And why not
heart disease, or diabetes, or even Aids? If lizards can regrow their tails,
and bees can fly even though it should be aerodynamically impossible for
them to do so, then why can't the intelligent homosapien spin a little
magic when it comes to repairing his own ailing torso? This river runs
deep; the questions lead us to the core of our belief systems about health
and illness, life and death, and the power and innate wisdom of the human
physical system. Whatever definitions and philosophies we may bat around,
there's no question anymore that a strong, resilient immune system is bolstered
and maintained by a well-balanced, nutritionally superior diet.
-
- GOOD AS GOLD: THE MIDAS TOUCH
-
- It's curious how the most innocent cliches ring true..."Living
off the fat of the land," can be taken literally. While petroleum
products may be referred to as "black gold" by those in a position
to profit, those liquid oils existing naturally in the bounty of our planet's
edible gifts to mankind--in grains, vegetables, nuts and seeds--should
be thought of as the common man's "amber or yellow gold." The
essential fatty acids (omega 3's and 6's) they abundantly provide are actually
one of the keys to vibrant health and a valuable preventative medicine
against dis-ease. So as you
-
- take that final glance across the crackers, snacks, cereals,
and soups standing erect in your cupboard, past the frozen dinners, prepared
desserts, sauces, and salad dressings adorning the inside of your icebox,
remember that a little interior redecorating in these areas of your home
just may save your life. After all, wasn't it Shakespeare who penned "To
thine own (health) be true?" Considering his origins as a grain merchant
in the little village of Stratford upon Avon, I'm sure he'd agree, oil's
well that ends well once you've got the real facts on fats.
-
- AS A MATTER OF FAT...
-
- In a nutshell, what's wrong with modern storebought oils?
-
- TASTELESS: Fresh, natural seed oils have the delicate
aromas and flavors of the seeds from which they are pressed. Bland, refined
oils have replaced their hearty relatives, and we have come to believe
that "tasteless" products are the norm. DE-VITALIZED: The new
widespread application of chemicals to seed crops increased yields, while
simultaneously introducing never-before-seen toxins and carcinogens to
people's diets. Edible oils have become contaminated with pesticide residues
that interfere with nerve functions and oxidation processes, consequently
lowering our vitality. What's more, the invention of chemical extraction
methods introduced gasoline-like solvents into our oils such as Hexane
and Heptane, which are lung irritants and nerve depressants. Even very
tiny (homeopathic) doses can have powerful detrimental effects on health,
or when accumulated in our tissues over a lifetime of use. TOXIC: The methods
used to refine oils produce dozens of potential toxins by random processes
unable to be controlled. Different batches contain widely varying, unpredictable
amounts and types of unnatural fat breakdown products. Trans-fatty acids,
polymers, cyclic compounds, aldehydes, ketones, epoxides, hydroperoxides,
and others still unidentified are just a few of the nasty invaders. Carotene,
vitamin E, lecithin and other naturally-occurring preservatives in the
oils were considered "impurities" and removed in the quest to
produce chemically "pure" (ie. sterile) oils. Synthetic antioxidants
were then developed to replace them, added artificially in order to restabilize
the strip-mined, nutrient-impoverished oils and extend their shelf life.
However, these chemicals interfere with our body's energy production, cell
metabolism, and respiration, as they fail to fit into the precise molecular
architecture of our enzyme systems and membranes. Over time, they may contribute
to a variety of degenerative diseases.
-
- STRIP MINING OUR OIL FIELDS
-
- Practically all of the complex, important, and healthful
molecules in refined oils have been removed, altered, or destroyed, including:
PHOSPHOLIPIDS: Such as Lecithin, which contributes significant fat- emulsifying
and membrane functions; PHYTOSTEROLS: Which block cholesterol absorption
from our intestine; ANTIOXIDANTS: Vitamin E complex, Carotene, and their
precursors, which protect oils against damage in storage, preventing the
rancidity that may contribute to the development of cancer. In addition,
they act as free radical scavengers in the human body and are indispensable
to our immune system's ability to fight off disease and infection; CHLOROPHYLL:
The green substance in plants, rich in magnesium and beneficial to the
digestive system; AROMATIC and VOLATILE COMPOUNDS; and MINERALS.
-
- As our diets have become deficient in these important
nutrients, many health-conscious consumers decide to purchase them separately
as bottled supplements off the shelves of supermarkets and natural food
stores, in effect having to "pay twice" for things that should
have been left in our foods in the first place. The refined "white
fats" and "white oils" are nutrionally equivalent to denatured
white sugar and flour in carbohydrate nutrition: protein-less, de-mineralized,
de-vitaminized, fiberless, empty calories. They cannot be properly digested
and metabolized, robbing our body of its stores of minerals and vitamins,
and leading to deficiency of essential nutrients and fatty acids.
-
- DROPPING ACIDS
-
- It's no hallucination that the inclusion of refined (and
exclusion of unrefined) oils in our diets has contributed to the dropping
of a pair of major league players from our culinary defense team. The key
components of fats that heal, and which we must obtain from foods in order
to be healthy, are the two Essential Fatty Acids (EFAs):
-
- a) LINOLEIC ACID ("LA" or cis-W6 polyunsaturated
fatty acids) abundant in safflower, sunflower, corn, sesame, and other
oils. Molecularly, it looks like a caterpillar bent in two places. The
minimum amount necessary is small and easily met by a starch-centered diet.
Approximately one-half of the fats found
-
- in vegetables are of this form; however, animal products
are low in it and can fail to satisfy the requirement.
-
- b) ALPHA-LINOLENIC ACID ("LNA" or cis-W3 superunsaturated
fatty acids), which looks like a caterpillar bent in three places. Flax
oil is the richest source, while hemp oil contains both w3 and w6 EFAs
in an ideal long-term ratio of 3:1. Although marijuana is illegal, both
hemp oil and the steamed unsproutable seeds are not.
-
- The distinction is important since, although they appear
quite similar, many of their physical effects are opposite in nature. As
our bodies cannot manufacture these, if either is missing or deficient
in the diet, cells deteriorate and, inevitably, deficiency symptoms will
gradually develop. Experts have recently begun to suggest that EFA deficiency
(especially w3) is far more widespread than previously believed. The symptoms
closely resemble those of diseases of fatty degeneration. Tissue or blood
levels of such disease victims are often low in w3 EFAs, and they respond
well to dietary increases in EFAs and essential minerals and vitamins required
for EFA metabolism. Flax oil is the quickest way to reverse a longstanding,
widespread w3 deficiency...a dozen 8.5 oz. bottles of good-quality flax
oil consumed over the course of a few months. However, its long-term exclusive
use may result in w6 deficiency symptoms, as it contains three times less
of these EFAs. It is highly unstable and spoils quickly, so must be processed
carefully. Linoleic and Linolenic fatty acids are extremely temperamental
and may be easily destroyed by light, air (oxygen), and heat. Nature packages
these oils in seeds that shut out these destructive agents and may even
protect them for years without spoiling. However, when the oil is extracted
from such seeds, special care must be taken in processing, packaging, and
storing EFA-rich oils from the time before pressing until the oil is consumed.
Such conditions are expensive and the necessary care is not usually taken.
-
- OIL FIRES: GETTING BURNED
-
- 1) LIGHT, the greatest enemy, produces free radicals
in oils and speeds up the reaction with oxygen by 1000 times, resulting
in rancidity. Light-induced free radical reactions can break EFAs down
into many different kinds of toxic and non-toxic components, and the vital
biological properties of EFAs are destroyed. 2) OXYGEN, even in the absence
of light, breaks down EFAs, resulting in rancid oils which emit a characteristic
unpleasant smell and bitter, fishy, or painty taste. Dozens of products
form, with toxic or unknown effects on our body's functions. 3) HEAT destroys
EFAs by twisting their molecules from a natural "cis" shape to
an unnatural "trans" shape, resulting in the formation of "trans-fatty
acids." Very high temperatures are applied in the
-
- deodorizing, hydrogenation, and deep-frying (commercially
or in- home) of processed or manufactured consumer food items. Believe
it or not, many heat-processed oils can still be sold as "cold-pressed,"
because there is no commonly accepted definition for this term. If no external
heat was applied while the oil was being pressed, it may qualify for this
description.
-
- Fresh EFA-rich oils should be pressed and packaged in
the dark, in the absence of oxygen, and with minimal heat, then stored
in opaque containers to prevent future exposure, and shelf-dated. Freezing
them solid does no damage and helps them remain unspoiled for a long time.
They ideally should be shipped directly by the manufacturer to retailers
or consumers without stops along the way. The more possibility for exposure
to the elements, the greater the chance of them becoming rancid and dangerous.
-
- A MANUFACTURER'S DREAM
-
- Hydrogenation, the most common yet detrimental process
by which to drastically change natural oils, was patented in 1903 and introduced
on a large scale in the 1930's. Its purpose is to provide inexpensive,
spreadable (plastic) products such as margerines and shortenings (cheaper
substitutes for butter and lard, respectively), as well as to increase
shelf stability--all at the expense of nutritional value. The first commercial
hydrogenated shortening--CRISCO by Procter & Gamble--went on sale in
1911. The term "Hydrogenation" describes an artifical saturation
of fully refined oils with hydrogen molecules in order to harden them into
spreadable products. Oils are reacted under pressure with hydrogen gas
at high temperature (248 to 410 degrees F) in the presence of a metal catalyst
for 6 to 8 hours. Although platinum or copper are sometimes used as the
catalyst, the most common added is "Raney's Nickel," containing
50% nickel and 50% aluminum. Remnants of both heavy metals remain in the
foods to be eaten by unwary consumers. The presence of aluminum is a definite
health hazard, now coming to be associated in the medical literature with
Alzheimer's Disease (mental senility), osteoporosis (softening of the boney
skeleton), and even as a facilitator in the development of cancer. A completely
hydrogenated oil takes the form of a very hard fat that has no essential
fatty acid (EFA) activity whatsoever. Essentially a dead substance, it
is unable to be spoiled or further damaged by additional cooking processes
(whether fried, baked, roasted, or boiled). The saturated fatty acids it
contains are stored by our bodies in triglycerides (molecules of fat or
oil) and membranes or used for energy. The human system has no need for
hydrogenated oils whatsoever, yet may be harmed in several ways. The unnatural
fatty acid fragments and other altered molecules (many toxic) supplied
are burdens on the body, in addition to the above-mentioned contamination
by a metal catalyst. While consumption of raw tropical products appear
to lower cholesterol levels, the same tropical oils when hydrogenated have
been shown to increase cholesterol. These saturated fatty acids (bad guys)
tend to crowd out essential fatty acids (good guys ingested from other
food sources) from our enzyme systems, resulting in EFA deficiency and
upsetting the delicate balance of prosta- glandins (fatty acids with hormone-like
functions that regulate cell activity). Tropical oils such as coconut or
palm kernel (which are between 80-90% saturated to begin with) have numerous
commercial applications when completely hydrogenated and, thereby, chemically
inert. They fit the bill for use in chocolate products which have the requirement
of remaining solid in the package yet being soft enough to melt in our
mouth. They can assist in extracting oil-soluble substances from other
plant tissues, such as the flavors of onion or garlic. Or they can be mixed
with natural liquid oils to make a margerine-like "vegetable spread"
that is virtually free of trans-fatty acids.
-
- BEING PARTIAL TO HYDROGENATION
-
- Manufacturers have the power to stop the hydrogenation
reaction at any point, when the desired degree of "hardening"
has been achieved, and this amount of control is a main seduction for industry
to use the process. It allows cheap oils to be manipulated into semi-liquid,
plastic, or solid fats with many variations in permeability, including
specific "mouth feel," texture, spreadability, and shelf life.
Margarines, shortenings, shortening oils, and partially hydrogenated vegetable
oils are the Frankensteins created in the frightening laboratories of the
modern day edible oil industry, and these bastard sons of originally healthful
ancestors can be located on the labels of almost every processed or packaged
food for sale today. When the hydrogenation process is not brought to completion
as such, these "partially hydrogenated oils" contain many dozens
of intermediate substances. So many altered compounds result that it staggers
the imagination...in fact, scientists have barely scratched the surface
in determining all the chemical changes that this process induces in fats.
Impossible to control or predict quantities or types of substances that
may be formed, each batch is literally a "witch's cauldron" of
mysterious, distorted fatty ingredients and toxins. Needless to say, the
industry is hesitant to fund systematic, thorough studies on this topic
or to publicize information that already exists in research journals--no
doubt aware of the detrimental health effects involved and afraid to substantiate
them further.

- YOUR TASTE BUDS OR YOUR LIFE
-
- Trans-fatty acids (TFAs), just one of the many altered
fat substances that result from this structural butchering of natural oils,
bring twice as many food additives into our diet as all other food additives
from all food sources combined. They interfere with our biochemical processes
in many ways: increasing cholesterol, decreasing beneficial high-density
lipo- protein (HDL), obstructing our liver's detoxification system, and
blocking the function of essential fatty acids (EFAs). Research studies
measuring the content of TFAs in commercial products have recorded margerine
samples as containing from 20- 60%, while the EFA content was virtually
non-existent (less than 5%). Considering that an average of 40 grams of
margerines and shortenings are ingested daily, it's not surprising, then,
that these products contribute the bulk of these dangerous compounds found
in the diet. The human body is so adversely affected by these substances
that the Dutch government decided to ban the public sale of all margerines
containing trans-fatty acids. (Incidentally, they enjoy the longest life
expectancy among industrialized nations, 5 years more than Americans.)
Additionally, a 1980 government committee in Canada expressed concern enough
to recommend that a minimum 5% Linoleic Acid (LA) be required in all margerine-like
products, since the presence of TFAs demands a higher content of this nutrient
in order to compensate for the inhibition of its functions. Herbert Dutton,
one of North America's oldest, most knowledgeable oil chemists, is convinced:
"If the hydrogenation process were discovered today, it probably could
not be adopted by the oil industry...The basis for such comment lies in
the recent awareness of our prior ignorance concerning the complexity of
isomers formed during hydrogenation and their metabolic and physiological
fate." (Isomers are altered chemical substances whose properties have
been changed.)
-
- ENDING OUR in-FAT-uation WITH FAT
-
- Approximately one-third of all edible oil is either partially
or fully hydrogenated: Frozen dinners, baked goods, confections (such as
ice cream, chocolate, candy), and snack foods (such as crackers and potato
chips) almost unanimously stowaway these oils, which help give a product
its crispy texture, creamy buttery texture, or make grains and cereals
more tender. As Udo Erasmus recommends in his book, FATS THAT HEAL, FATS
THAT KILL: "The market for limp potato chips is small, the health
cost for crunchy ones is high. Why not eat whole potatoes?" He suggests
adopting the custom of Mediterranean countries, where people dip their
bread in fresh, unrefined oils (virgin olive, flax, or hemp being the best)
instead of sloshing on a thick, hydrogenated paste. In DIET FOR A POISONED
PLANET, author David Steinman suggests becoming a responsible consumer:
"Any labels declaring that the oil used is hydrogenated should send
you a clear warning you are holding a product that serves no place in your
shopping cart...So when you see the word 'hydrogenated,' put the product
down!"

- More on the price of oil (in which we try to persuade
the true believers that the availability of oil and its price does have
an effect on our space age, cyber-economy)
-
- From an astute reader:
-
- "...(The) data quoted below starts with the year
1975. If you had started with 1972 it would have shown a very different
picture. The Arab oil embargo hit in the winter of '73-74 and prices rose
very sharply at that time. They have since declined but they remain higher
than the pre-1973 level...
-
- As your data shows, oil prices have been very unstable
over the past 25 years, which has little to do with technology or supply
and demand but much to do with politics and particularly with the ability
of OPEC to control the price. They lost control of the market somewhere
in the mid-1980s when non-OPEC states developed reserves that had been
discovered in the 1960s.
-
- However, the peak years for oil discovery were in the
1960s, not during the period of high prices. Extensive exploration during
the latter period failed to uncover extensive new reserves (unless you
believe the "political reserves" claimed by OPEC states). We
are now consuming oil at a rate roughly four times the discovery of new
oil. In a few years, OPEC will once again be in a position to control the
market, and they will begin raising prices..."
