Cholesterol Concerns...?
As a result of
all of the misinformation which has been spread about coconut
oil over the past 30 years as well as the constant media
harping on the dangers of fat and cholesterol we are frequently
asked the following question: "Isn't coconut oil bad
for my cholesterol?"
Although this
question is discussed in the various references on our "coconut
info links" page, we have decided to address it here
specifically for those who don't want to dig through all of the
other references. For the answer to this question we quote the
book, Know Your Fats, by Mary Enig, Ph.D. " (Who is Mary Enig?)
"The
following is an exchange in 1999 with a European-based
journalist.
Question: Specifically, I
would like [a] comment on the veracity and accuracy of this
report, which I got off the Internet, from India's Health
Education Library for People (HELP) organization. In
particular, I would be interested in whether [you agree] that
the MCFA v. LCFA distinction gives coconut oil the advantages
in digestion that this article says it does and, if so, why
experiments have shown it to increase deposits of cholesterol.
THANKS...
Here is the
text: "Coconut oil is rich in saturated fat, which is why it is
bracketed with animal fat by many people. It should be noted
that coconut oil has no cholesterol, as the latter is a
component of animal fat only. However, intake of saturated fat
may result in the elevation of the blood cholesterol levels.
But all oils are not the same. Coconut oil is a good food, as
most of its saturated fatty acids are what we call medium-chain
fatty acids (MCFAs). They account for nearly 64% of the fatty
acids in coconut oil. It is only coconut oil and palm kernel
oil, among all of the edible oils, that contain these good
MCFAs.
All other
vegetable oils and the animal oils contain long chain fatty
acids (LCFAs).
The only
exception is butterfat, with 12% short chain fatty acids.
Unfortunately those who equate coconut oil with other
saturated fats do not know that there are different varieties
of saturated fats. Coconut oil is, therefore, different from
all other oils containing saturated fatty acids. Being a MCFA
oil, coconut oil has certain definite advantages over other
LCFAs. The digestion of coconut oils is faster and starts
almost in the mouth itself and undergoes complete digestion in
the stomach and upper intestine not requiring the pancreatic
juice lipase for its digestion. It also has better solubility
in biological fluids, getting absorbed directly into the portal
blood and carried to the liver directly to undergo rapid
oxidation to release energy. Other oils and animal fats
containing LCFAs need pancreatic lipase for their digestion and
do not easily mix with biological fluids, and so are absorbed
after being re-esterified inside the intestinal cells into
triglycerides. They are first incorporated into large insoluble
particles called chylomicrons by the intestinal cells. These
then go to the liver via the lymphatics and the circulatory
system, thereby going round all parts of the body before going
to the liver for final oxidation. They are, therefore, more
likely to get deposited as fats and also change the blood fat
content. Coconut oil, therefore, does not produce any
significant change in the circulating VLDL [very low density
lipoprotein], which is supposed to be bad for vessel
thickening. (Emphasis ours.)
