What is Virgin Coconut Oil (VCO)?
Virgin Coconut Oil is derived from the fresh
meat or kernel of a mature fruit of coconut rather than the sundried
coconut meat known as copra.
Virgin Coconut Oils are produced one of two
ways:
- Quick drying of fresh coconut meat, which is
then used to extract the oil by mechanical means.
- Wet-milling method. Coconut milk first is
extracted from fresh coconut meat by mechanical pressing. The oil is
then extracted from coconut milk by way of boiling, fermentation,
refrigeration, enzymes or mechanical centrifuge.
What are the differences between quick drying
and wet-milling method?
Quick drying method definitely involves
heating, whereas wet-milling method may or may not involve heating
depending on the oil extraction process from coconut milk. Both methods
produced Virgin Coconut Oils of nearly colourless, had slightly
detectable acid aroma, sweet and salty tastes, and perceptible nutty
aroma and flavor. Cooked coconut with sweet coconut aromas were
generally associated with Virgin Coconut Oil, which were heated.
Whereas rancid attributes describe the Virgin Coconut Oil, which were
none heated. Acid and rancid aromas were highly correlated. For
details, click “Descriptive sensory evaluation of virgin coconut oil
and refined, bleached and deodorized coconut oil.”
What are the differences between Virgin Coconut
Oil and Coconut Oil derived from copra?
Virgin Coconut Oil is water clear in colour,
has mild sweet coconut aroma. Virgin Coconut Oil is chemical and
additive free, and is the purest form of coconut oil. Whereas, coconut
oil derived from copra is known as copra oil. Copra oil is yellow in
colour, odourless, slightly salty and has no perceptible flavours. It
has to undergo chemical refining, bleaching and deodorization processes
before they can be fit for human consumption. Copra oil is yellow in
colour because of bacterial contamination of the copra before oil
extraction and due to high processing temperature. For details, click
here. Moreover, copra oil is often partially or fully hydrogenated
to increase its melting point. This may produce trans fats.

Aren’t coconut oils bad for health?
Virgin Coconut Oil is currently a hot topic
due its benefits to human consumption and the researchers’ challenge on
the dogma, which is the domination of diet-heart hypothesis in
atherosclerosis research.
Coconut oil is a fat consisting of about 90% saturated fat. Saturated
fat was widely “labeled” as unhealthy fats, which was once believed to
cause heart disease. Researchers since early 1950 have focused on a
single hypothesis or idea – the diet-heart idea,
sometimes called the lipid hypothesis, which proposes a sequence of
etiologic relations between the saturated fat content of the diet,
serum cholesterol concentrations, and the development of disease.
Until recently, most epidemiological and clinical investigations of
diet and Coronary Heart Disease (CHD) have been dominated by the
diet-heart hypothesis. However, the original hypothesis was overly simplistic because the effects of
diet on CHD can be mediated through multiple biological pathway other
than serum cholesterol or LDL.
The tropical oils are coconut oil and palm oil being the saturated fats
are the victims behind the over simplistic diet-heart hypothesis. The
conclusion of an analysis of the history behind the diet-heart
hypothesis was that after 50 years of research, there was no
evidence that a diet low in saturated fat prolongs life.
Fifty years later, researchers started to challenge the dogma of
diet-heart idea, the strong belief of saturated fat causes heart
disease has started to shake. And was later found that trans fats cause
the disease, not saturated fats. However, there is common misconception
of trans fat and saturated fats. The term “trans fat” and
“saturated fat” is interchanging.
Trans fats are formed during the process of hydrogenation. The process
of unsaturated fats is to imitate the physical properties of saturated
fats, in which, to become solid at room temperature. Thus, the
unnatural saturated fats are produced. Trans fats and saturated fat are
both solid at room temperature, their similarities end there. You can
find the differences between trans fat and saturated fat here.
All the research of the past 50-plus years proving saturated
fats to be "harmful” had failed to
differentiate between saturated fats and trans fats. Except
for the trans family, all fatty acids in particular the saturated ones
raise the good HDL cholesterol. And now, there is good
reason to believe that trans fats – not saturated fats – are
the true cause of heart disease, obesity and other degenerative disease.
“The full story about saturated fat and heart
disease is very complex and much of it remains a mystery.
…we don't know exactly what causes arterial blockages, or why some
people who eat large amounts of saturated fat have comparatively
healthy arteries.”

“For the past 50 years, saturated fats have
been taking the blame for problems caused by trans fats. It is time for
consumers to be enlightened.”

The Framingham Heart Study, started in 1948 and
still on-going, is one of the biggest research projects on heart
health. In 1992, study leader Dr William Castelli wrote in Archives of
Internal Medicine: “In Framingham, Massachusetts… the people who ate
the most cholesterol, ate the most saturated fat, ate the most
calories, weighed the least and were the most physically active.”

Internal Medicine, 1992 Jul; 152(7): 1371-1372

What are the Benefits of Virgin Coconut Oil?
The benefits of virgin coconut oil:
- Abundant in Medium Chain Triglycerides for
Boost of Metabolism and Loss Weight
- Abundant in Lauric acid and strengthening
of Immunity System.
- Can withstand wide heat ranges without
oxidation and free radical formation.
- Delicious coconut flavor and aroma.
Abundant in
Medium-Chain-Triglycerides (MCT) for Boost of Metabolism and Loss Weight
- Coconut oil was previously mistakenly
believed to be unhealthy because of high saturated fat content.
- Majority (Some 98 to 100%) of fats and oils
we consume whether saturated or unsaturated composed
of Long-Chain-Triglycerides (LCT). LCT
circulate in our blood stream. LCT are slow to metabolise and
readily deposit as body fat.
- Coconut oils has high percentage of Medium
Chain Fatty Acids (generally about 64%), or known as Medium-Chain-Triglycerides (MCT), which do
not circulate in blood stream and are therefore do
not block our blood vessels.
- MCT oils are sent directly to liver
for immediate convert into energy, and are fast to metabolise,
therefore, coconut oils increase the metabolism rate.
- Recent studies confirmed the potential
of MCT to reduce body weight and particularly body fat.
However, this effect was not transient. For details, please read "Medium-chain
triglycerides increase energy expenditure and decrease adiposity in
overweight men."
Abundant in Lauric Acid and
strengthening of Immunity System
- Virgin coconut oil is known as Lauric oil
due to high Lauric acid content (50%).
- Body converts Lauric acid into fatty acid
derivatives – monolaurin, which is the substance for anti-viral,
anti-bacterial or protozoal.
- Lauric
acid is naturally found in mother’s milk, which protects baby
against viral and bacterial infection.
Can withstand wide heat ranges
without oxidation and free-radical formation
- Coconut oil is not easily damaged by heat.
- It does not readily oxidise like unsaturated
oils do when heated, leading to free-radical formation.
- Nor does it turn into a trans-fat on heating.
Delicious coconut flavour and aroma
- Copra oil is bland in taste due to the
Refine-Bleach-Deodorise process. However, Virgin Coconut Oil has the
mild sweet coconut flavour and aroma.

Are there any bad things about
Virgin Coconut Oil?
Yes, there could be especially if your body is not accustomed
to high fat in the diet and if you are taking it for the first time.
The most common side reaction is diarrhea.
However, this type of diarrhea is not accompanied by stomach pain or
stomach spasms unlike the usual diarrhea that is caused by toxins or
food poisoning.
You will just have a liquid bowel movement which is in a way could be
considered as removing toxins from your intestines. So for first
timers, do not start with the full 3 tablespoons dose. Instead, start
with one tablespoon for a few days and gradually increase the intake as
your body becomes acclimatized to it until you reach the full dose. You
can also take it in divided doses at different times of the day instead
of taking at one time the full 3 ½ tablespoons full dose.
