Does
Coconut Oil Affect Cholesterol Levels?
I imagine everyone is different, but here's
my experience so far. In 2004 at age 61 I
had a mild heart attack and blocked artery.
My total cholesterol was 101 in the
hospital. A couple of months later it was
134, after taking my cardiologist's drug
store. I stopped all drugs after that,
realizing after researching them that they
were worthless. I then came across virgin
coconut oil. I have been taking between four
and six tablespoons per day with meals since
then. The results-
2004 HDL 45,LDL 73,TRIG 81,LDL/HDL Ratio
1.6, Total 134
2005 HDL 73,LDL 111,Trig 47 LDL/HDL Ratio
1.5, Total 193
2006 HDL 97,LDL 113,Trig 39,LDL/HDL Ratio
1.2, Total 218.
My next test will be in December. My 2005
results literally shocked my cardiologist.
He said HDL doesn't increase like that in
people my age. I also passed a nuclear
stress test last year. I saw my regular
doctor last week, and he said I'm beating
the odds on not having another attack. I
think the [Virgin Coconut] oil along with a
change of diet is the reason why.

Population Studies
Coconut
oil (and all saturated fats) has been blamed for many years as a cause
of increased cholesterol levels, which supposedly leads to heart
disease. But studies done on traditional tropical populations that
consume large amounts of coconut oil show just the opposite. One of the
best ways to study the affects of coconut oil on human nutrition is to
look at tropical populations that get most of their caloric intake from
the saturated fat of coconut oil. Logic would dictate that if the
saturated fat/cholesterol theory of heart disease and obesity were
correct, those populations with the highest consumption of saturated
fats would be the most overweight and have the highest rates of heart
disease. Such is not the case.
In a
study published in 1981, the populations of two South Pacific islands
were examined over a period of time starting in the 1960s, before
western foods were prevalent in the diets of either culture. The study
was designed to investigate the relative effects of saturated fat and
dietary cholesterol in determining serum cholesterol levels. Coconuts
were practically a staple in the diets, with up to 60% of their caloric
intake coming from the saturated fat of coconut oil. The study found
very healthy people who were relatively free from the modern diseases of
western cultures, including obesity and heart disease. Their conclusion:
"Vascular disease is uncommon in both populations and there is no
evidence of the high saturated fat intake having a harmful effect in
these populations."1
I had been taking Tropical Traditions Coconut
Oil for obvious health benefits when I realized one day that my knees
weren't hurting, so I stopped for a day or two and they hurt again. I
have one artificial knee, and one that isn't in very good shape, and
they used to hurt all the time. When I resume the oil, the pain goes
away, so that makes me very happy. Also, my cholesterol went from 242
to 218. I take about 2 teaspoon/day and haven't gained any weight,
although I eat anything I want, so it works for me. Darleen

Another
study was done on the Indian subcontinent comparing traditional cooking
oils with modern oils in relation to prevalence of atherosclerotic heart
disease and Type-II diabetes. Their conclusion: "In contrast to earlier
epidemiologic studies showing a low prevalence of atherosclerotic heart
disease (AHD) and Type-II dependent diabetes mellitus (Type-II DM) in
the Indian subcontinent, over the recent years, there has been an
alarming increase in the prevalence of these diseases in Indians--both
abroad and at home, attributable to increased dietary fat intake.
Replacing the traditional cooking fats condemned to be atherogenic, with
refined vegetable oils promoted as 'heart-friendly' because of their
polyunsaturated fatty acid (PUFA) content, unfortunately, has not been
able to curtail this trend. Current data on dietary fats indicate that
it is not just the presence of PUFA, but the type of PUFA that is
important--a high PUFA n-6 content and high n-6/n-3 ratio in dietary
fats being atherogenic and diabetogenic. The newer 'heart-friendly' oils
like sunflower or safflower oils possess this undesirable PUFA content
and there are numerous research data now available to indicate that the
sole use or excess intake of these newer vegetable oils are actually
detrimental to health and switching to a combination of different types
of fats, including the traditional cooking fats like ghee, coconut oil
and mustard oil, would actually reduce the risk of dyslipidaemias, AHD
and Type-II DM."2
When
measurements of serum cholesterol (cholesterol levels in the blood) were
first done, only the total of both HDL ("good cholesterol") and LDL
("bad cholesterol") were read. Now that testing has become more
sophisticated, researchers look more at the balance of these two types
of cholesterol. They note whether a substance raises cholesterol levels
of HDL or LDL levels. In some cases, certain foods lower total
cholesterol, but only by lowering good HDL cholesterol while at the same
time actually raising levels of the bad LDL cholesterol. Studies now
show that coconut oil actually increases the good HDL cholesterol, while
lowering LDL. So total cholesterol levels may actually increase, but in
a very favorable ratio.
I have
been on Virgin Coconut Oil (VCO) since early June (1T per day in oatmeal
and using it on my skin). I had a blood test performed at the end of
August. My total cholesterol did go up since last year from 168 mg/dL to
187 mg/dL currently as did my Triglycerides from 60 mg/dL to 72 mg/dL
(all within normal range). My HDL ("good" cholesterol) jumped from 60
mg/dL to 85 mg/dL! My LDL ("bad" cholesterol) dropped from 96 mg/dL to
87 mg/dL. My Cholesterol/HDL ratio dropped from 2.8 ratio units to 2.2
ratio units. I live in a dry climate, but my skin is soft and smooth
from using VCO. I find that the oil rids my face of wrinkles as others
on the list have experienced. When I have dinner with my son at the
restaurant where he works, his co-workers assume that I am a friend his
age. They don't believe him when he tells them that I am his mother. I
had gained 20 pounds from forced inactivity due to disc problems in my
back, but I have lost those and am now a size 4-6 again. I will
definitely keep using the VCO.

Faulty
Science
In a
lecture given in Viet Nam in 1996, Dr. Mary Enig stated that “The
problems for coconut oil started four decades ago when researchers fed
animals hydrogenated coconut oil that was purposely altered to make it
completely devoid of any essential fatty acids. The animals fed the
hydrogenated coconut oil (as the only fat source) naturally became
essential fatty acid deficient; their serum cholesterol increased. Diets
that cause an essential fatty acid deficiency always produce an increase
in serum cholesterol levels as well as in increase in the
atherosclerotic indices. The same effect has also been seen when other
highly hydrogenated oils such as cottonseed, soybean or corn oils have
been fed; so it is clearly a function of the hydrogenated products,
either because the oil is essential fatty acid (EFA) deficient or
because of transfatty acids.”3
What
about studies where animals were fed unprocessed coconut oil? Enig
wrote: "Hostmark et al (1980) compared the effects of diets containing
10% coconut oil and 10% sunflower oil on lipoprotein distribution in
male Wistar rats. Coconut oil feeding produced significantly lower
levels (p=0.05) of pre-beta lipoproteins (VLDL) and significantly higher
(p=<0.01) alpha-lipoproteins (HDL) relative to sunflower feeding.”4
She also cited a study by Awad (1981) on Wistar rats fed a diet of
either 14% (natural) coconut oil or 14% safflower oil. She stated:
“Total tissue cholesterol accumulation for animals on the safflower diet
was six times greater than for animals fed the [unhydrogenated] coconut
oil. A conclusion that can be drawn from some of the animal research is
that feeding hydrogenated coconut oil devoid of essential fatty acids (EFA)
potentate the formation of atherosclerosis markers. It is of note that
animals fed regular coconut oil have less cholesterol deposited in their
livers and other parts of their bodies.”5
Do
Saturated Fats Clog Arteries?
Saturated fats are probably the most maligned fats in the popular media
today. They are often blamed for "clogging arteries" and leading to
heart disease. However, an examination of the research and science
behind saturated fats leads one to a vastly different conclusion,
suggesting that the attacks against saturated fats have been primarily
political and economical, and not scientific. While we will provide a
brief summary of the science behind saturated fats here, we encourage
you to examine the research more closely yourself. Much of it is
documented at www.coconutoil.com.
First of
all, saturated fats are essential to our health. They comprise about 50%
of our cell membranes, and some proportion of saturated fats are found
in all fats and oils, whether plant based or animal based.
In
recent years some have made claims that too much saturated fats in our
diet can lead to higher cholesterol levels and clogged arteries, which
leads to heart disease. So an anti-saturated fat campaign was launched
in the U.S. in recent years. As a results, Americans have consumed less
saturated fats than any other nation, yet the U.S. is still a world
leader in deaths from heart disease. Obesity rates are also at an
all-time high. Many are now questioning the "wisdom" behind the low-fat
nutritional advice that has dominated the popular media (see Gary Taubes
article "The
Soft Science of Dietary Fat.")
Does
research support the claim that saturated fats like coconut oil raise
cholesterol levels and clog arteries? This "lipid theory" of heart
disease, which blames high cholesterol levels as causing heart disease,
is seriously being questioned by researchers and doctors. Malcom
Kendrick M.D., Dr. Mary Enig Ph.D., Uffe Ravnskov M.D., Ph.D (author of
The Cholesterol Myths), George Mann M.D., Sc.D, and many other top
researchers have written extensively on the flaws of the “cholesterol
theory” of heart disease.
As to
the research on "clogged arteries", a study was done at the Wynn
Institute for Metabolic Research, London, examining the composition of
human aortic plaques. This study found that the "artery clogging fats"
in those who died from heart disease were composed of 26% saturated fat:
the rest (74%) were polyunsaturated fatty acids, such as those found in
vegetable oils commonly consumed in today's modern societies. Their
conclusion: "No associations were found with saturated fatty acids.
These findings imply a direct influence of dietary polyunsaturated fatty
acids on aortic plaque formation and suggest that current trends
favoring increased intake of polyunsaturated fatty acids should be
reconsidered."6
My
doctor wanted me to start taking pravachol to lower my cholesterol,
which was 219. He said because you are diabetic, I don't want you to
have a heart attack once your blood sugars are under control. I told him
I wanted to see if I could bring my cholesterol down naturally with VCO
and eating right. I began taking VCO last spring when I read about it in
Woman's World Magazine. At the time I had a lot of problems with
hypothyroid, fibromyalgia, IBS, candida, super dry skin and skin rashes,
etc. I have stopped taking all meds for my gastrointestinal symptoms and
my skin is now silky soft and smooth. My blood work done on December 4,
2003 showed my cholesterol was down 31 points to 188 mg/dl.

Hi
I don't post often but felt I had to on this one. I just got back from
the Dr.'s office and my total cholesterol went [down]. My doc was SO
happy. I've been going to her for over 15 years and dreaded every time I
got the blood test. It was always the same thing - a lecture. I had
always used olive oil for years but started using coconut oil for most
of our cooking (olive oil occasionally). My cholesterol results after at
least 15 years of being high: triglycerides was 187...now 109.
Cholesterol, total was 260...now 185. Chol/hdlc ratio...5.41...now 4.1.
Glucose....105...now 94. My doctor was ecstatic. I believe I already
mentioned this, but I can now use these statistics for anyone that gives
me a hard time [about using Virgin Coconut Oil.] Sally Ann

Virgin Better than
Refined Coconut Oil
A
recent study done in India comparing refined coconut oil (CO) with
Virgin Coconut Oil (VCNO) found that VCNO obtained by wet process has a beneficial effect in
lowering lipid components compared to CO. It reduced total cholesterol,
triglycerides, phospholipids, LDL, and VLDL cholesterol levels and
increased HDL cholesterol in serum and tissues. The results demonstrated
the potential beneficiary effect of virgin coconut oil in lowering lipid
levels in serum and tissues and LDL oxidation by physiological oxidants.
This property of VCNO may be attributed to the biologically active
polyphenol components present in the oil.
I use virgin coconut
oil, olive oil, and butter in my cooking and
add extra virgin coconut oil to my
smoothies, and I also eat coconut oil just
by the tablespoon. My total cholesterol went
down over 100 points. HDL and LDL were
great! My coworkers could not believe I was
eating so much fat and watching my
cholesterol levels go down. I had to take a
fasting [blood] test to prove it to them. I
have lost 18 pounds in three months. I have
learned a new way of life and it’s easy. I’m
healthier for it, too. I will never count
calories again!
