During
my university years, I used to frustrate my parents by throwing away egg yolks
and eating only the whites. No worries, I thought, as my parents just didn't know
enough to realize that I was reducing my risk of heart disease by avoiding cholesterol.
Looking back, I'm sure that my parents were wondering how I could so easily toss
away egg yolks that their families were able afford only a few times a year in
Korea in the 1940s.
Today,
I am grateful to have a better understanding of the relationship between cholesterol
and my health. How about you? Are you afraid of having high cholesterol? Are you
throwing away your egg yolks because you think it's good for your health? Are
you taking cholesterol-lowering medication or considering it?
If
you answered yes to any of these questions, I hope that you will consider the
work of Uffe Ravnskov, MD, PhD, author of The Cholesterol Myths : Exposing the
Fallacy that Saturated Fat and Cholesterol Cause Heart Disease. I consider Dr.
Ravnskov to be the world's leading expert on the relationship between cholesterol
and human health.
Here
are some facts from his book:
Cholesterol
is not a deadly poison, but a substance that is absolutely necessary for you to
be healthy. High cholesterol itself does not cause heart disease.
People who have low blood cholesterol have the same rates of heart disease as
people who have high blood cholesterol.
The
cholesterol found in your blood comes from two sources: cholesterol in food that
you eat and cholesterol that your liver makes from other nutrients. What's interesting
is that the amount of cholesterol that your liver produces varies according to
how much cholesterol you eat. The more cholesterol you eat, the less your liver
produces. And vice versa - the less cholesterol you eat, the more your liver produces.
This is why a low cholesterol diet does not decrease a person's blood cholesterol
by more than a few percent.
Drugs
that solely lower your cholesterol do not decrease your risk of dying from heart
disease, nor do they increase your lifespan. These drugs pose dangers to your
health and may decrease your lifespan.
The
newer cholesterol-lowering drugs - called statins - do reduce your risk of heart
disease, but through mechanisms that are not related to lower blood cholesterol.
Unfortunately, statins like lipitor, mevacor, zocor, pravachol, and lescol are
known to stimulate cancer in rodents.
Dr.
Ravnskov's book provides solid evidence that supports these and other facts that
have me convinced that many doctors don't have a clue about cholesterol and health.
Sadly, conventional guidelines that promote lowering your cholesterol for a healthy
heart are influenced in large part by large pharmaceutical companies that are
making billions of dollars with cholesterol-lowering medication.
Here
are my personal guidelines on cholesterol, based on my research and evaluating
the blood test results and health of hundreds of people I have worked with over
the past several years.
Blood
cholesterol of 150 (3.9 in Canada) or lower is not healthy for most people. Low
cholesterol over the long term can cause depression, increased risk of stroke,
and numerous problems related to hormonal imbalances. If you are not getting enough
vitamin D from your diet, having low cholesterol can lead to vitamin D deficiency,
as sunlight can only create vitamin D in your body by acting on cholesterol found
in your skin.
Your
HDL/total cholesterol ratio should be at least 25-30 percent. The higher this
ratio, the better. If this ratio is 10-15 percent or lower, there is a high risk
of eventually having a heart attack.
You
want to have your triglyceride/HDL ratio be lower than 2.0.
If
your HDL/total cholesterol and tryglyceride/HDL ratios are in the ranges listed
above, and you are eating mainly undamaged cholesterol, having a total cholesterol
of more than 200 (5.2 in Canada) is not a problem. In fact, even people whose
genetics cause them to have total cholesterol above 350 (9.0 in Canada) have been
shown to have no elevated risk of heart disease as long as their ratios are fine
and they stay away from eating damaged cholesterol.
If
you haven't already done so, be sure to check out our article
here that discusses damaged and undamaged cholesterol.
I
hope that you will join me in never throwing away another egg yolk.
Speaking
of eggs, so many of the guests who have visited our clinic have benefited from
our guidelines on eggs that I wrote them up in a separate article. You can read

Just a note to let you know how much I appreciate your
newsletter. As a fellow health care provider (optometrist) and medical researcher,
I find your distillation of the literature into lay terms to be accurate and very

Thanks for your excellent health newsletter. I look
forward to it every week. Thanks for providing the best online health resource
I have found. - Moorea Maguire
I'm sure as a doctor you hear
your share of complaints. I just thought you'd like to know that there's at least
one person in your "e-audience" that appreciates the time and effort you put into
sending the emails. I really look forward to them. - Linda H., Raleigh, North
Carolina
Many of my adult ESL students are Korean, and enjoy bits
and pieces from your newsletter that I have shared with them. In addition to your
logical approach to health, I enjoy sharing your newsletter because your English
is unfailingly correct as well as easily understood. Thank you for your beautiful
approach to life. - J. Zetterstrom
I thank you and your staff
for such a great website. I am former National Level Bodybuilder so I know a thing
or two about health and fitness. Your site is very valuable and I do my best to
pass it on to friends and people I train. It is also a helpful resource in my
career as a human service provider working with clients who need to recover from
substance abuse. I believe a major part of recovery is getting your body and mind
feeling healthy and strong. Thank you again! Great Website! - Michael Christopher,
