It is time to go on an anti-cholesterol crusade.
“What!?” you ask. “Half the people in the world have been marching
with the cholesterol crusade for decades; they don’t need any help
from me!”
I don’ mean a crusade against cholesterol or cholesterol-containing
foods, I mean…
A CRUSADE AGAINST THE CHOLESTEROL MYTH.
After reading last month’s Letter, you
should feel a sense of urgency in your obligation to help your
patients know the truth about cholesterol. You may be unique among
all the professionals your patients know in your grasp of the truth
that:
• Elevated serum cholesterol is not a cause of heart
attacks and strokes.
• Eating foods high in cholesterol is not a cause of
elevated serum cholesterol, and therefore…
• Eating high cholesterol foods is not a cause of heart
attacks and strokes, and in fact…
• It is the foods high in cholesterol and saturated fat (such as
eggs, meat, fish, and poultry) that will actually keep serum
cholesterol down to normal levels.
Do understand, however, that we are not saying high serum
cholesterol is good, or even that it is clinically insignificant.
Quite the contrary, high serum cholesterol definitely indicates the
presence of a metabolic imbalance. It is just that the high
cholesterol component of that metabolic imbalance has no specific
relation to the risk of cardiovascular disease (CVD). In other
words, your patients with high cholesterol have problems. The
elevated serum cholesterol may be an indicator of an anaerobic
imbalance, of a dysaerobic imbalance, of a thyroid insufficiency, of
an electrolyte stress imbalance, of a glucogenic imbalance, and so
on. High serum cholesterol definitely indicates a patient with an
imbalanced body chemistry or inefficient metabolism. But:
• The elevated serum cholesterol is the result of the
problem, not the cause of the problem.
• The metabolic imbalance that caused the high serum cholesterol
may, indeed, increase that patient’s risk for cardiovascular
disease, but if it does so it is not because of the presence of
elevated serum cholesterol per se, but because there will also be
found elevated triglycerides, and usually low HDL
cholesterol, elevated homocysteine, and elevated c-reactive protein
(see below).
If the presence of cholesterol in the serum has absolutely nothing
to do with the risk for heart attacks and strokes, just what is the
pathological process involved in cardiovascular disease? Consider
what you have read in past Letters about the association between
triglycerides and insulin resistance and cardiovascular disease,
then let’s take our discussion a step further. [By the way, a NUTRI-SPEC
Letter I’ve given to countless patients, is the one from November,
2000, entitled, “The Deadly Quartet.” Give it to all your patients
who have elevated triglycerides, or who test ketogenic. Ask for a
free copy with your next order. Your patients must understand
the relationship between dietary sugar, elevated triglycerides and
CVD. That letter tells the whole story.]
One of the most fundamental causes of atherosclerosis is not the
presence of cholesterol, but the oxidation of cholesterol
(particularly of LDL, the so-called “bad” cholesterol). Oxidized LDL
is dangerous; it promotes the destruction of blood vessels by
creating a chronic inflammatory response. Oxidized LDL can
also provoke the release of metalloproteinase enzymes. These enzymes
cause blood vessel destruction, partly by interfering with the HDL
(“good” cholesterol) protective effective.
Another component of atherosclerosis (in addition to oxidation and
inflammation) is the excess proliferation of cells on the inside
lining of arteries; this proliferation is in response to a
chronic inflammatory state. Healthy arteries are lined with a smooth
layer of cells, while diseased arteries become thick and overgrown
with cells.
The other component of the risk from atherosclerosis involves
platelet aggregation, or the thickening or clumping together of
blood cells (one important component of your Electrolyte Stress
imbalance). Thromboxane (from the Prostaglandin family) is the blood
vessel constricting agent that contributes to abnormal platelet
aggregation, and is a major contributor to heart attacks and
strokes.
We cannot make the point strongly enough that elevated serum
cholesterol is not a primary risk factor for cardiovascular
disease. As you’ve seen from the study showing that 40% of people
with heart attacks and strokes do not even have elevated
cholesterol, cholesterol is worthless as a predictor of
cardiovascular disease. Low HDL cholesterol is a valid
predictor but not nearly as reliable as elevated triglycerides and
elevated homocysteine.
More recently, another almost infallible indicator of the likelihood
of cardiovascular disease is none other than serum C-reactive
protein. C-reactive protein has, of course, always been one of
the serum tests recommended as important to compliment a Nutri-Spec
profile. Why? It is the best indicator of a chronic inflammatory
state.
It has now been shown that elevated C-reactive protein is one of the
best predictors of CVD risk. One series of studies shows that
between 25-35 million Americans have total cholesterol within normal
range, yet have above average risk of cardiovascular inflammation,
which has a significant impact on heart disease risk, and which is
perfectly well indicated by C-reactive protein. Those with the
highest levels of C-reactive protein have five times the risk of
developing cardiovascular disease, and seven times the risk of
having a heart attack or stroke compared to subjects with normal
levels. Furthermore, C-reactive protein predicts risk of
cardiovascular events even in women who have no other pertinent risk
factors.
Those of us who do Nutri-Spec and are ever on the alert for signs of
estrogen stress, will note that estrogen replacement therapy
has been clearly shown to increase the risk of heart attack; and now
it has been shown that estrogen causes C-reactive protein to rise.
The Framingham study showed a strong correlation between elevated
C-reactive protein and calcification of the coronary arteries.
[FLASH ALERT! Headline news --- Estrogen Is Convicted of Killing
Thousands of Unsuspecting Women!. In the biggest medical news
story in decades, the increased risk of cardiovascular disease
resulting from the use of estrogen replacement therapy has been
quantified. Remember, for years and years the medical/pharmaceutical
establishment had promoted estrogen as a protector of menopausal
women from heart attacks and strokes. Research (that was published
but never managed to be publicized) has shown for years (and you as
a NUTRI-SPEC practitioner have been aware of it) that just the
opposite is the case --- estrogen actually increases a woman’s
chance of suffering CVD. Two months ago we reported that even the
Journal of the American Medical Association had admitted that
hormone replacement therapy increases a woman’s chance not only of
cancer, but of heart disease (a 29% increase after only 5 years) and
stroke (a 41% increase) as well. This shows that the damage done by
estrogen is far worse than even I anticipated. A study done in
Denmark and published in the British Medical Journal in February of
this year, shows that the risk of having a heart attack among
diabetic women who have used estrogen replacement is an unbelievable
nine times higher than normal.]
Research on C-reactive protein confirms what many other studies have
shown over the last several decades, that cholesterol-filled plaques
in blood vessels may not pose any real danger unless
they are affected by inflammation, and unless there is oxidative
damage. Inflammation weakens plaques, making them more vulnerable to
bursting or pinching off a clot that can then block coronary
vessels.
One theory on the development of cardiovascular disease hypothesizes
that plaques are not the pathology, they are actually an attempt on
the part of the immune system to repair oxidative damage to blood
vessel walls.
Well-established cardiac risk factors such as obesity, smoking,
hypertension, and chronic periodontal disease all increase
inflammation and C-reactive protein. Interestingly, fat cells
produce tremendous quantities of C-reactive protein, which is one
additional reason why being overweight is such a cardiovascular
disease risk factor.
As we Nutri-Spec practitioners know, one of the key pro-inflammatory
substances with which modern Americans are almost universally
overwhelmed is the Omega 6 fatty acids from polyunsaturated
vegetable oils.
Some researchers have suggested that the Staten drugs for lowering
cholesterol show a slight, but statistically significant benefit in
preventing heart disease, but do so not because they lower
cholesterol, but because they have some anti-inflammatory activity
and lower C-reactive protein. Similarly, aspirin, which has been
credited with reducing the incidence of heart disease and strokes by
thinning the blood, may actually have its beneficial effect because
it is an anti-inflammatory that reduces C-reactive protein, rather
than due to its anti-platelet blood thinning effects. The same can
be said about vitamin E, which, while it does have some blood
thinning effect, has now been shown to decrease inflammation and
considerably lower C-reactive protein levels. Another factor that
helps lower C-reactive protein is a high protein, high saturated
fat, low carbohydrate diet.
Consider what you have now learned about the true nature of the
pathology underlying CVD. You can clearly understand that the most
direct and effective way to minimize our risk for CVD is to
accompany our Nutri-Spec Fundamental Diet with Taurine, and the
powerful antioxidants in Diphasic AM and Diphasic PM.
It has also been shown that not only is C-reactive protein an
inflammatory marker and predictor of cardiovascular disease, but it
also serves as a warning sign for the onset of Alzheimer’s Disease
and other forms of senile dementia associated with the presence of
vascular inflammation. One study showed that men with high
C-reactive protein have three times the risk of developing
dementias, and that that risk is predicted years before clinical
symptoms appear by elevated C-reactive protein. C-reactive protein
is also likely linked to the incidence of ischemic stroke and
transient ischemic attacks.
Now that you are developing a complete picture of the complexity of
vascular disease, you should also begin to appreciate that you, as a
Nutri-Spec practitioner, are uniquely in a position to actually do
something about it. In the discussion of C-reactive protein above,
we mentioned the use of your Taurine supplement as a way to minimize
CVD risk.
The amino acid (technically, it is actually a sulfonic acid) Taurine
that we have long promoted for its protective role on the heart and
blood vessels has had much additional research in the last few years
confirming its amazing clinical power. An Australian study published
in the Asia Pacific Journal of Clinical Nutrition 2001; 10(2):134-7,
showed that Taurine is one of the key properties in fish that
protects against cardiovascular disease.
A large-scale study in Japan drawing from 24 populations in 16
countries revealed a strong inverse association between Taurine
levels and ischemic heart disease. This was published in
Hypertension Research 2001 JUL; 24(4):453-7.
Researchers at the University of South Alabama found that congestive
heart failure responds favorably to Taurine therapy. Their study was
published in Amino Acids 2000; 18(4):305-18.
A study published in Clinical and Experimental Pharmacology and
Physiology, 2001 VOL 28, ISS 10, 809-815, described mice bred for
severe high cholesterol and atherosclerosis being fed Taurine for
three months. Even though their (genetically predetermined)
cholesterol levels were still significantly elevated after
treatment, Taurine reduced the area of arterial lipid accumulation
by an astounding 28%. There was also a decrease in the size of
lesions in the aorta. The blood levels of the oxidative stress
marker TBARS were significantly decreased by the Taurine as well.
Thus, while it has been long known that Taurine lowers elevated
cholesterol in humans, it is now seen that Taurine prevents the
formation of atherosclerotic lesions independently of blood
cholesterol levels.
Most impressive of all is the study published in the January 7, 2003
issue of Circulation showing that smokers initially have blood
vessel diameters much smaller than non-smokers. Yet, after taking
just 1.5 grams per day of Taurine for only five days, the smokers’
blood vessel diameters increased to equal that of non-smokers.
If you are getting the big idea from all these research studies we
are quoting, you now understand that it is not the presence of fats
in the arteries that leads to degenerative changes, but the
oxidation damage to blood vessel walls that leads to CVD.
Thromboxane (prostaglandins), homocysteine, deficient HDL
cholesterol protective effects, excessive oxidation of the LDL
cholesterol, the oxidative damage associated with advanced glycation
end products (AGEs) (associated with insulin resistance as indicated
by elevated triglycerides), and C-reactive protein, are all signs of
inflammation and oxidative damage.
