Summary
14 million Americans
have heart disease and more than 2,600 die daily from heart attacks in the
United States alone. 15% of adults in their late 30s to 40s are afflicted
by cardiovascular disease, about 50% of 55 to 64 year-olds, and 65% of those
will be afflicted in the next decade.
After 20 years of aggressive drug therapy and promotion of low-fat diet,
the tide on cardiovascular disease has not reversed. Obviously, this elusive
condition is far more complicated that we had ever imagined. It is clear
that there are other factors that have not being addressed
Cause
of Cardiovasular Disease
For decades, the public at large has been taught that the key culprit to
heart disease is high cholesterol in our blood that comes from a diet that
is high in cholesterol. This notion must be downgraded.
Consider the following:
· Polar bears, for example, maintain total blood cholesterol of over 400
mg/dl and they seldom develop heart attacks.
· Eskimos are relatively free of heart disease. They eat animal fats from
fish and marine animals liberally.
· The Okinawans are the longest living population group in the world. The
average life span for Okinawan women is 84 years. Their diet? An intake
of fish 2-3 times a week and high intake of vegetables. Their cholesterol
intake on the whole is more than most.
· People in North India consume 17 times more animal fat but have 7 times
fewer incidences of heart disease compared to people in southern India.
In the Framingham study for example, men and women consumed an average cholesterol
intake of 700 mg and 500 mg per day respectively (one egg provides 200 mg).
The average serum concentration of cholesterol for men and women with higher
than average cholesterol intake was found to be 237 and 245 mg/dl respectively.
Subjects with lower than average intakes has an average serum concentration
of 237mg/dl for men and 241 mg/dl for women. The difference is statistically
insignificant. Statistically, studies have shown that
people who consume 4 eggs per week
actually have average serum cholesterol (193 mg/dl) same as those who reported
consuming only 1 egg per week (197 mg/dl). Clearly dietary cholesterol in
and of itself is not the critical link to heart disease risks as we once
thought.
Today, few experts deny that the low-fat
message of the past three decades is radically oversimplified.
If nothing else, it effectively ignores the fact that mono-unsaturated fats
like olive oil is full of omega-3 fatty acid, which is good for health and
must be consumed in large amounts. Bad fats such as overcooked saturated
fats from meat or trans-fat from processed food should be avoided.
While a diet high in unhealthy fat can promote heart disease, it is only
one of many factors that increase cardiovascular risk. Science is telling
us that in fact, it is only a minor reason. Other than the familiar hypercholesteremia,
the main reason for high blood cholesterol
is excessive metabolism of oxygen and sugar in our blood stream due
to the polluted environment, and a diet high in refined carbohydrate, trans-fat,
and stressful lifestyle. This leads to free radical generation that in turn
damages the endothelial wall of the blood vessel. The body has an intrinsic
repair mechanism to overcome the damage, but it needs the proper nutrients
to get the job done. Some nutrients are made internally, while others need
to be supplied externally. In the case of blood vessel repair, the key is
ascorbic acid. It cannot be made endogenously and has to be taken in externally
from food sources.
Sad to say, but the food we take in today is far different from that our
grandparents ate. They simply cannot provide all the nutrients needed by
the body to repair the damaged endothelium. Our soils are depleted of nutrients,
the amount of chemicals and preservatives are at an unprecedented high level,
and the way we cook our food with high heat is nothing short of extreme.
The wholesome meal that our grandparents ate is now replaced by frozen and
processed food when we are not able to go to a fast food restaurant. Even
the 65 mg of Vitamin C in one orange gets only fractionally delivered to
our body by the time it makes the journey from the orchard to our kitchen.
Our body was never designed to take in large quantity of glucose from breakdown
of pasta, bread, French fries, cookies, and soda over years. It simply does
not have the ability process them properly without residual damaging effect.
Lacking the specific nutrients in order to carry out the repair process
properly, the body puts its emergency repair team into action. It instructs
the liver to produce cholesterol (a sticky and waxy substance) as a surrogate
in its attempt to repair damaged artery by covering the damaged areas. Cholesterol
so produced travels from the liver to the damaged areas as LDL cholesterol.
It is further converted into oxidized LDL cholesterol and sets off a cascading
inflammatory reaction. This eventually leads to a thrombus formation, reduction
of nitric oxide synthesis, high blood pressure, and ultimately blockage
of blood vessels resulting in heart attacks or strokes.
A high cholesterol blood level can therefore be viewed as a sign of underlying
vascular wall dysfunction at the endothelium and defect in our insulin’s
activity against glucose. Unfortunately, this has gone unrecognized. Instead,
the cholesterol myth has lead researchers to focus on stopping the production
of cholesterol from the liver by the use of drugs.
Advanced
Markers of Cardiovascular Disease
The all out assault on lowering cholesterol
has failed to reduce the incidence of heart disease because the root cause
of heart disease does not lie in cholesterol alone. To use total
cholesterol and LDL as a surrogate end point in measurement of cardiovascular
disease risk is rudimentary at best given the amount of scientific research
available.
Are there any alternative markers that
help us formulate a more complete picture of heart health from multiple
angles? Indeed there are, they have been known for years. However,
most of these markers have been ignored because there are no drugs available
to “normalize” them. No doubt as drugs are developed, these markers will
take on significant commercial value, and that is when their importance
will be publicized. At the mean time, as most medical students were taught:
Never order a test when you know ahead of time you’re not going to know
what to do with the results.
It is far better to incorporate the following sensitive and easily
obtainable indicators when assessing cardiovascular risk. They are listed
in decreasing order of importance (the most important and sensitive listed
first), as follows:
1. Lipoprotein (a) – indicator of
endothelial wall integrity
2. Homocysteine – indicator of free
radical activity
3. Fibrinogen – indicator of
thrombus formation and blood viscosity
4. Arterial Stiffness
–indicator of wall flexibility and blood pressure health
5. Cellular Energy Generation
– indicator of mitochondrial function
6. C Reactive Protein – indicator
of inflammatory response
7. Triglyceride – leading cause
of metabolic syndrome
8. Total cholesterol / HDL cholesterol
ratio –key indicator in lipid metabolism
9. LDL cholesterol – indicator
of the level of “bad” cholesterol
10. Total Cholesterol – overall
indicator of total cholesterol in blood.
As we can see, cholesterol is near the
bottom in terms of sensitivity and predictability of cardiac accidents when
compared to others.
This paper will examine each of these markers in more detail and suggest
conventional and nutritional therapeutics that can normalize each of these
indicators.
While none of these key indicators are
in and of themselves and an absolute prognosticator of impending heart attack
or stroke, there is little doubt that taken as a group, the overall predictive
value of these indicators are overwhelming significant and have strong predictive
value. They offer the best that science can offer today, short
of scans and invasive procedures.
1.The
Lp(a)
Autopsy studies of heart attack victims have shown that many have clean
vessels and normal cholesterol levels. It is obvious that there are other
causes for heart disease. Indeed, researchers with the Framingham Heart
Study (the decades-long study that brought us the term "risk factor")
identified a relative of LDL-cholesterol called lipoprotein
(a) [Lp(a)], which is now recognized as major independent risk factor for
heart disease. While LDL cholesterol maybe known as the "bad"
cholesterol, Lp (a) is even worse. Lp(a) is a plasma lipoprotein that structurally
resembles LDL, but with additional adhesive properties. Some of the natural
cholesterol produced by the liver in response to free radical damage is
converted into LDL cholesterol and its relative Lp (a). Lp(a) fosters cholesterol
deposition by enhancing oxidation of LDL-cholesterol. It is the oxidized
form of cholesterol that penetrates the endothelium, leading to the build
up of plaque and vascular disease. It
should be noted that artery blockage (plaque) is composed mainly of Lp(a)
and not of ordinary cholesterol
Oxidized cholesterol is a free radical generator. Research has shown that
rabbits that consumed a small amount of oxidized cholesterol for merely
12 weeks had atherosclerosis plaques that were two times as big as the control
population. Studies reveal that heart attack risk falls 2% for every 1%
drop in LDL cholesterol level.
Studies have also shown that Lp(a) holds fast to damaged blood vessel, attracting
other Lp(a) molecules, and finally constituting the atherosclerotic plaques.
In fact, a high Lp (a) level (more than 30 mg/dl) has been revealed to carry
a 10 times greater risks for heart disease than LDL cholesterol level.
Linus Pauling, two-time Nobel Laureate, postulated that Lp(a) may be the
surrogate for ascorbate in the human. Low dietary intake of ascorbate leads
to weaken blood vessels because ascorbate is required for the synthesis
of collagen and elastin, which strengthen the blood vessel wall. In the
absence of ascorbate, Lp(a) is mobilized to repair these structural defects
in arterial walls by being deposited to strengthen the tissue. However,
if the plasma concentration of Lp(a) is too high, the process goes too far.
Too much Lp(a) gets deposited in the arterial wall, and plaque formation
is initiated.
Chronic depletion of these essential nutrients such as vitamin C, lysine,
and proline in the endothelial and vascular smooth muscle cells impairs
their ability to function properly. Guinea pigs fed a diet low in ascorbate
rapidly developed atherosclerotic plaques, similar to those found in humans.
When large amounts of supplementary ascorbate were given to these guinea
pigs, there was a regression in plaque formation.
Because humans, other primates, and guinea pigs do not produce ascorbate
endogenously, they have to be supplemented from external source. Dr. Pauling
concluded that the optimum intake of Vitamin C is perhaps 100 times more
than the RDA (RDA is 85 mg ). During the last 25 years of his life (he died
at age 93 from cancer), Dr Pauling increased his own intake of Vitamin C
many times, taking 3,000 mg to 18,000 mg per day. This amount is consistent
with the amount of ascorbate in animals that are capable of producing their
own on a daily basis. Dr. Pauling believed that cardiovascular disease is
the general result of ascorbate deficiency.
Lp(a) is a simple blood laboratory test
to perform. The optimum laboratory level should be under 20 mg/dl and preferably
under 14 mg/dl. Currently, there is
no medicine or drugs that effectively lowers Lp(a) to this level.
A high Lp(a) is genetically linked. The
most effective and natural way to normalize it is a nutritional cocktail
consisting of high dose Vitamin C ( 4-6 grams), L-lysine (2-4 grams), and
L-proline ( 1-2 grams). Other synergistic amino acids such as glutamine,
ornithine, and pine bark extract should also be included. Because high dose
vitamin C can lead to diarrhea, it is very important to incorporate the
fat-soluble form called ascobyl palmitate. Being fat soluble, this
form of vitamin C stays in the body much longer than regular vitamin C and
in effect extends the efficacy of vitamin C in the body while at the same
time reduces the amount of vitamin C needed.
This mega vitamin cocktail therapy will increase blood concentrations of
important substances and focuses on:
· Strengthening and healing damaged blood vessels
· Lowering LP(a) blood levels
· Inhibiting the binding of LP(a) molecules on the walls of blood vessels
This concept of endothelial repair advanced by Dr Pauling to lower Lp(a)
is simple and logical. Once the endothelium
is healed, the body will not send a signal to the liver to produce cholesterol
and its related products such as LDL and Lp(a). The
key is to focus on the endothelium and not focus on the liver.
Many conventionally trained physician uses niacin or statin drugs to
reduce Lp(a). This works to a limited extent. Statin drugs have some
Lp(a) lowering effects by suppressing its production in the liver, but this
is a band-aid approach and comes with side effects. Niacin also reduces
the production of Lp(a) in the liver, and helps to reduce its blood level
. However, this approach has its limitations because until the endothelial
wall is optimized and cleared, the Lp(a) level will not be reduced significantly.
The effects of niacin or statin drug therapy usually hit a plateau after
9-12 months of therapy. The Lp(a) level seldom goes below 30mg/dl because
until the endothelium is healed, the body will always instruct the liver
to make cholesterol.
On the other hand, with the proper nutritional cocktail focusing on endothelial
repair, drastic improvements on Lp(a) level can usually be seen within the
same time frame for the majority of the people. The higher the starting
value, the more significant is the reduction.
It is not unusual for the Lp(a) level to be slightly elevated from its baseline
level in the early months of therapy ( as it is cleared from the arterial
wall into the lumen) before normalizing. This is normal and is not a cause
for alarm. A follow up Lp(a) test should be done 9-12 months after starting
the nutritional program. While the majority responds favorably, some people
are particularly resistant, and may take up to 1 year to effect a minor
change. In a very small group or people, no change at all can be expected
after an extended period. The good news is that there are no negative side
effects. All people with high Lp(a) should be started on a nutritional cocktail
program. Even if repeated blood tests do not show any improvement, vascular
integrity is enhanced. There is nothing to loose and everything to gain.
2.
Homocysteine
Homocysteine is an amino acid by-product of food metabolism. It contributes
to atherosclerosis, reduces the flexibility of blood vessels, and increases
clotting by making platelets stickier and slows blood flow. Studies show
a direct positive correlation between high serum homocysteine levels and
the risk of heart attack and stroke.
A high homocysteine level is also associated with Alzheimer's disease, as
well as depression, multiple sclerosis, menopausal symptoms, and rheumatoid
arthritis.
Homocysteine is formed naturally when protein is broken down. Too
much of it causes oxidative damage to the endothelium. Oxidative
damage is caused by free radicals--byproducts of the body's normal processes
that can damage body tissues. In fact, the risk for heart disease triples
when the homocysteine blood level exceeds 15.8 umol/L - a reading still
considered by many to be within the "normal” range (The optimum target
should be under 8 umol/L). Worse yet, the odds of heart disease are directly
proportional to the homocysteine concentration. The higher the blood homocysteine
level, the higher the risk of cardiac disease.
This direct correlation has been well researched, including a study conducted
at the University of Bergen of 2127 men and 2639 women aged 65 to 67 years
between 1992 and 1993. By February 1997, 162 men and 97 women had died;
121 from cardiovascular causes (including stroke), 103 from cancer, and
33 from other causes. Using a baseline homocysteine level of 9.0 umol/L
the researchers found that for every 5.0 umol/L increment increase in homocysteine
levels, all-cause mortality increased by 49%, cardiovascular mortality by
50%, cancer mortality by 26%, and deaths from other causes (respiratory,
gastrointestinal and central nervous system diseases) by 104%.
Looking at it another way, dropping the
homocysteine level by 5 points can reduce heart disease risk by 50%.
These percentages refer to values obtained after adjusting for a variety
of lifestyle factors including cholesterol level, blood pressure, smoking,
body mass index, physical activity, age, sex, and baseline cardiovascular
disease risk. About 78% of this study group had homocysteine levels at or
above 9.0 umol/L and 12% had levels exceeding 15 umol/L. It is interesting
to note that Smoking and drinking coffee were associated with higher homocysteine
levels while taking vitamins and exercising were associated with lower levels.
The result is clear – for optimum heart health, lower the homocysteine level.
In another study published in the Journal of the American College of Cardiology
(June 1, 2001;37:1858-1863), researchers found that heart disease patients
who took 5 milligrams (mg) of folic acid daily ( not microgram or mcg) for
12 weeks had slightly better functioning of their arterial inner lining,
or endothelium, and a greater ability to widen their arteries appropriately,
than those who took an inactive placebo.
Sad to say, but only 11 percent of all Americans get enough folic acid
from its main sources - liver, kidney, broccoli, beef, kale, turnip
greens, and beats. Cooking destroys as much as 90 percent of a food's folic
acid content. The average American over 50 years old only takes in 130 mcg
of folic acid per day. The RDA is 400 mcg a day. Its level is also depleted
by chronic alcohol consumption and medications such as anticonvulsant. In
fact, studies have shown that eating 400 mcg of folic acid from food alone
does not raise the serum folic acid concentration anywhere close to that
obtained by simple folic acid supplementation. You need more than what food
can provide.
Drugs easily deplete folic acid as well. The NSAID anti-inflammatory drugs,
including aspirin and ibuprofen, deplete folic acid. The popular class of
anti-ulcer drugs known as the H-2 receptor antagonists [Zantac, Tagamet,
Pepcid, etc.] also depletes folic acid.
Instead of encouraging simple folic acid supplementation, the US Food and
Drug Administration implemented a policy of mandating that certain food
be "enriched" with folic acid in 1998. Since that time, folic
acid has been added to certain grain products including cereals, breads,
pasta and flour. This has resulted in higher folic acid levels in adult
Americans. Unfortunately, the amount of enrichment, while enough to protect
the pregnant women and the fetus from neural tube defect, is hardly enough
for optimum health. Only 636 mcg is present per pound of such "enriched
food”. While some of these foods are good, the majorities fall in to the
category of "junk food" because of its high grain and refined
sugar content. Clearly, eating such “junk food” as a method to supplement
folic acid is not the best way to optimize health.
There are no medications or drugs that can effectively reduce homocysteine level.
How much folic acid do you need?
RDA: 400 mcg a day
For heart heath: 400 mcg 800 mcg a day
To lower serum homocysteine level: 3-20 mg a day
3.
Fibrinogen
Fibrinogen is a key indicator in heart disease risk. In one study of 116
men, it was found that people who have high LDL (bad) cholesterol but low
fibrinogen level had only 1/6 the heart attack risk of men with high LDL
level and high fibrinogen levels. High fibrinogen levels promote the spontaneous
formation of fibrin clots and increase the risk of heart disease. Reducing
the level of fibrinogen is therefore an important part of a heart disease
prevention program.
A clot is also known as a thrombus. It is formed when platelets and red
blood cells come together. It is formed at the sight of the clot from soluble
circulating protein called fibrinogen. This protein binds the clots together,
and is naturally formed in the blood after injury or trauma. The injury
could be severe, as when a blood vessel breaks. The injury could also be
very minor from shear forces and stress of the blood flowing in the blood
vessel to free radical attack on the endothelial wall caused by pollutants
and sugar. During the aging process, when the collagen structure of the
blood vessel wall is weakened, clots may also form. Fibrin also increases
the blood viscosity, blood pressure, and impairs blood flow. Complete blockage
results in heart attack or strokes.
Laboratory testing of fibrinogen is simple
and easy. However, its use has not gained widespread acceptance though,
because there are no direct drug based treatments for elevated levels available.
Normal range = Males 180-340 mg/dl, Females 190-420 mg/dl.
Plasmin
While there are over 3000 enzymes in the body and there are more than 20
enzymes involved in the coagulation cascade that creates blood clots, there
is only one enzyme that Mother Nature has provided to the human body that
can dissolve the fibrin and break up blood clots. This enzyme is called
plasmin. Unfortunately, the body's production of this decline with age.
In addition to its decreased production with age, fibrinogen levels also
rises 25mg/dl per decade in healthy people. In other words, as we age, our
plasmin level reduces while our fibrinogen level rises. The resulting risk
of cardiac accidents goes up.
Plasmin is called a thrombolytic (clot-dissolving) enzyme and is made from
plasminogens through the action of the enzyme called Tissue Plasminogen
Activator (TPA). Acting on the same principal, a class of drug has been
developed that mimic this activity. For example, Urokinase is a drug that
belongs to a class of medication called Tissue Plasminogen Activities. It
is administered within a few hours after admission in to a hospital after
an acute onset of thrombus formation and is delivered intravenously. It
is also very expensive.
Are there natural compounds that have similar thrombolytic activities? Yes.
Let us take a closer look.
Natto
In 1980, after
studying physiological chemistry at the University of Chicago Medical School,
Japanese researcher Dr. Hiroyuki Humi discovered that a traditional Japanese
food called natto derived from fermented soy had the ability to dissolve
clots. Specifically, he was able to identify and purify the specific enzyme
in the fermented soy cheese that he called nattokinase. Natto has been
widely consumed in Japan as a condiment for over 1000 years.
Extensive studies have been conducted worldwide on this compound. In one
study, 12 volunteers, 6 men and 6 women, were fed 200g (7oz.) of natto and
had their thrombinolytic activities measured. Researchers found that the
time needed to completely dissolve a clot was cut in half in those taking
natto as compared to those who did not take it. In 1995, researchers did
a study wherein the corona arteries of rats were injured to induce thrombus
formation. The arteries were then completely blocked and blood flow to the
brain was stopped. Three enzymes-elastase, plasmin, nattokinase, were then
tested on different rats and the researchers found that nattokinase
was successful in restoring circulation by 62%, while plasmin was
able to restored it by 16% and elastase produced no reopening. Since natto
is a natural compound, its potency has to be standardized in order to have
relevancy to the studies. In Dr. Sumi's original nattokinase research paper,
it was reported that natto has an average of 40 fibrinolytic units (FU).
In human research, 50-200 gram is the typical daily food dose used to supply
nattokinase. This is equivalent to 2,000-8,000FUs. The nattokinase currently
available in dietary supplementation supplies about 20,000 FU/g. This can
be compared with serrpeptase, an enzyme from the silk worm that has fribrinolytic
properties with an equivalent of 60,000 FU/g.
Natto is a fermented cheese like food and it use as a folk remedy for
heart and cardio vascular disease has been well established. It is produced
using a fermentation process by adding a beneficial bacterium known as bacillus-natto
to boiled soybeans. The resulting nattokinase enzyme is then produced when
the bacillus natto acts on the soybean.
While soy food does contain a variety of enzymes, it is only in the natto
preparation that contains the specific nattokinase enzyme. Unfermented
soy products such as tofu or soymilk do not contain nattokinase.
Nattokinase produces a prolonged action in two ways: it prevents the coagulation
of blood and dissolves existing thrombus. Both the efficacy and the prolonged
action of nattokinase can be determined by measuring the levels of EFA (euglobulin
fibrinolytic activity) and FDP( fibrin degradation product) which will become
elevated as fibrin is dissolved. It has been shown that by measuring EFA
and FDP levels, that nattokinase activity can last from 8-12 hours.
Nattokinase has been subjected to 17 studies including 2 small human trials.
Nattokinase has also been used to lower blood pressure in Japan. In 1995,
researchers from Miyazaki Medical College and Kurashiki University of Science
and Arts in Japan studied the effects of nattokinase on blood pressure in
both human and animal subjects. With a single administration of 400-450g
of nattokinase infused into the peritoneal, there was a 12.7% drop in systolic
blood pressure within 2 hours of administration. When the same natto extract
was tested on human volunteers, it was shown that when 30g of lyophilized
extract, equivalent to 200g of natto food, were given, 4 out of 5 volunteers
had their systolic blood pressure reduced by 10.9% and their diastolic blood
pressure also reduced by 7%.
To guard against thrombus formation and to dissolve existing clots,
take 25 mg to 100 mg of nattokinase in the
form of nutritional supplements if you do not like to consume natto bean.
Make sure the FU value is more than 20,000 Fu/g .
4.
Arterial Stiffness
One of the hallmarks of aging is the loss of collagen supporting structure
throughout the body. Collagen reduction is visible and presents itself in
the form of wrinkles on our face and skin surfaces during the aging process.
Our blood vessel is also structurally supported by collagen. As
this collagen structure deteriorates, stiffening of the arteries occurs.
Indeed, the fact that arteries stiffen with age, and that such
changes are associated with an increased incidence of major cardiovascular
events and increase in blood pressure, is now established beyond doubt.
Measuring the stiffness of arteries would logically provide a better insight
into blood vessel health, in addition to the traditional blood pressure
measurement. Scientists have machines, with a reproducible parameter termed
'stiffness index' by measuring the time delay between direct and reflected
waves in the digital volume pulse. There are several apparatus commercially
available to physicians. Unfortunately, its use is not widespread because
there is no drug based treatment program to reduce the stiffness once discovered
As collagen is lost and elasticity reduced,
stiffening of the arterial wall lead to increase in systolic and diastolic
pressure. In particular, the systolic pressure will be disproportionately
higher, registering a reading of 140-160 mmHg or higher. There is often
a wide systolic to diastolic gap (normal is 40 mmHg), often up to 60-70
mg Hg, with a typical blood pressure reading of 160/100 mmHg without medication,
and 140/90 at best with medication.
Postural hypotension is also common. With reduced elasticity to normalize
blood pressure, it can drop quickly as a one goes from a sitting to a standing
position. Anyone over age 45 can practically assume that arterial stiffening
is already in a progressive state. Unless active steps are taken, the stiffening
will continue. Those who have elevated blood pressure should be specially
concerned as it may indicate arterial stiffening. Unfortunately, there are
no medications that can reduce the arterial stiffness at this time.
Nitric Oxide (NO)
In 1998, a trio of scientist’s was awarded the Nobel Prize for discovering
the enormous role that Nitric Oxide (NO) plays in our body. NO is the first
gas discovered to have signaling properties. It is produced by one cell
and is able to penetrate through the membrane and regulate the function
of another cell. The discovery of this pathway opens up an entirely new
principle of signaling and communications in the biological system.
Mention nitric oxide and most think of it as the toxic gas produced and
given off by a car engine. It is a poison that up until now is thought to
exist outside the body and does nothing more than cause trouble. NO was
not expected to be important in higher animals such as humans. This is now
proven wrong. NO in fact is produced inside most if not all tissues by the
body and plays a very important role in the cardio vascular, immune, and
nervous systems.
Nitrous oxide is known as the laughing gas, the anesthetic that is used
commonly by dentists. This should not to be confused with Nitric Oxide.
NO and the Cardiovascular System
NO is produced by the inner most layer of the arteries called the endothelium.
Once produced, it rapidly spreads through the cell membrane to the underlying
muscle cells, causing them to relax from its default-constricted state.
This results in the dilation and widening of the artery lumen. Blood pressure
drops as a result. Because NO is short lived, a constant supply of it is
generated by the endothelial cells in response to the sheer stress of the
blood flow on the artery walls. In arthrosclerosis, the endothelium has
been damaged by free radical attacks as well as plaque formation and inflammatory
response. The capacity to produce NO is reduced, and the vascular musculature
constricts and blood pressure can be elevated.
It is now known that normal cardio vascular contraction state is biased
in one direction, which is towards vessel constriction. This is the
body’s way of maintaining the blood pressure at a slightly constricted state
in order to channel adequate blood supply and oxygen delivery to the brain
continuously. With the constant NO production by the endothelium, vessel
dilation is sustained, and blood pressure is maintained at a normal systolic
rate of around 120 mm Hg and a diastolic rate of around 80 mm Hg. Too
much NO can lead to excessive vasodilatation and a fall in the blood pressure,
while too little NO can lead to rise in blood pressure.
The vasodilatation effect of NO applies to all blood vessels. It can initiate
erection of the penis by dilating the blood vessels to the erectile bodies.
This knowledge has already led to the development of new drugs to treat
impotency such as Viagra.
Any interruption the production of NO interferes with the tone of the arterial
muscles and the blood vessels will return to its constricted state. From
this point of view, a rise in blood pressure may due to the constriction
caused by other factors such as the hormone epinephrine produced by the
adrenal glands.
In the case of heart disease, the tension
is focused on NO deficiency. Healthy blood vessels are pliable
and elastic by nature. They can alter their diameter instantly in response
to a greater or lesser out flow of blood from the heart. This continuous
change happens during exercise as well as when we are excited. This spontaneous
regulation of blood pressure goes on uninterrupted 24 hours a day. As we
age, the elasticity of our blood vessels declines due to collagen loss,
free radical damage, as well as plaque accumulation. Poor diet, lack of
exercise, cigarette smoking, and genetic predisposition all contribute to
a breakdown of collagen fibers that support the blood vessels. This results
in the lack of elasticity. Blood vessels then become passive and stiff pipe-like
structures which raises blood pressure, forcing the heart to work harder.
In addition to helping the blood vessels relax, NO also helps to prevent
the clogging of arteries in several ways. First, it prevents the white blood
cells from sticking to the arterial wall. It also helps to prevent damage
to the arterial wall by reducing the production of free radicals. In other
words, it acts like an antioxidant. NO also helps to prevent the thickening
of the middle (muscular) wall of the artery that can narrow the opening
where the blood flows.
Other Function of NO
NO gas, when inhaled by patients with pulmonary hypertension has been shown
to relieve lung congestion. In a treatment for newborn babies, breathing
problems can be helped by inhaling NO that relaxes constricted blood vessels
and dilates the lung’s blood vessels. NO is also produced in the brain in
neuronal form that acts as a chemical messenger at the synapses. This has
opened up a new approach to the studies of Alzheimer’s disease, Parkinson’s
disease, and other neurological disorders. NO also inhibits the loss of
bone, and the release of growth hormone may augment bone density.
Exercise and NO
Exercise alone has also been shown
to increase the production of NO in the body. This may
explain why exercises can reduce blood pressure.
The effect of adding the amino acid arginine and vitamin C and E to an exercise
program have been shown to synergistically increased NO production. In a
study conducted at UCLA, researcher Louis Ignarro studied 6 groups of 8-week-old
receptor deficient male mice with high cholesterol over 18 weeks. The mice
were randomly divided into 3 dietary groups called fat with high cholesterol
diet alone, fat with high cholesterol diet with antioxidant vitamin E and
C, and a fat with high cholesterol with the antioxidants arginine. It was
shown that the mice from all 3 groups were able to lose weight and had lower
cholesterol when they exercised. The atherosclerotic legions were significantly
reduced in the mice group that had arginine.
The explanation is that exercise will increase the amount of endothelial
nitric oxide synthetase (NOS) and enzymes that will then convert the arginine
into NO, which in turn lowers abnormally elevated blood pressure, prevent
unwanted blood clots, and early inflammation associated with coronary artery
disease. Nitric oxide production is stabilized when vitamins C and E are
added as these remove destructive oxidants from the blood stream.
Even without exercise, these supplements will work on their own to increase
NO. Studies have shown that mice that were sedentary and fed supplements
alone showed a 40% reduction in atherosclerotic legions compared to mice
that were on a regular, high cholesterol diet but did not exercise or take
supplements.
Exercise alone without supplementation also shows a 35% reduction in legions.
It can be concluded therefore that amino acid supplementation has an atherosclerotic
reduction effect similar to exercise. Doing both exercise and supplementing
with antioxidants concurrently will produce the best results.
Formation of NO
No is formed in varies places in the body. In the endothelium, NO is formed
by the enzymatic action of nitric oxide synthetase (NOS) on the amino acid
arginine and citrulline . This process is enhanced when antioxidants are
present, especially vitamin C. NO also forms in nerve cells, where it spreads
rapidly in all directions and affects all cells in the vicinity. NO is also
produced in the white blood cells such as macrophages and NO is toxic to
invading bacteria and parasites.
There are 3 forms of NOS enzymes. One is in the endothelium, one in the
immune system, and one in the brain. Genes responsible for encoding the
NOS are located in chromosomes 12, 7, and 17 respectively. The discovery
of NOS opens up another new class of drugs based on n-monomethyl-arginine
(l-nmma), an inhibitor of the NOS enzyme. Drugs are being used to explore
the possibility of blocking NO production in order to raise the blood pressure.
Experiments have been performed where volunteers were injected with l-nmma.
Blood flow was then compared from one arm to the other arm. As l-nmma was
infused, blood flow is observed to gradually decrease to half as compared
to that in the control arm. This has important ramifications, and drugs
are being developed to raise blood pressure. Clinical application of this
pathway is be particularly useful for those who have acute low blood pressure
as frequently experienced when in shock or trauma.
L-Arginine and NO
L-arginine is an essential amino acid
that is present in many foods and it is also a precursor of NO production.
Studies have shown that arginine, when
taken in proper amounts, can stimulate NO production. In a 1999
study, 30 impotent men were given 1500 mg of arginine each per day. It was
shown that is worked no better than the placebo in terms of vasodilatation
and sexual performance. However, when 21 men with mild to moderate impotence
were given 3,000mg a day of arginine, significant improvement in erection
as well as sexual satisfaction was reported. This study was published in
the December 1998 issue of Hawaii Medical Journal. It is obvious that the
use of arginine as a nitric oxide precursor is dose dependant, and a low
dose regiment will not be effective.
L-arginine supplementation has also been shown to significantly reduce systolic
and diastolic blood pressure. Reductions were evident in subjects when they
were rested as well as when they were not stressed. The reduction in blood
pressure was associated with increased cardiac output. These findings were
reported in the in the American Heart Association meeting in November 2003
where 16 hypercholestrolemic men with normal blood pressure were given 12
grams of oral arginine a day over a period of 3 weeks.
L-arginine has long been used in the enhancement of sports performance and
cardiac function. A double blind placebo control study of 22 subjects with
stable angina and supplementation with l-arginine at 1 gram twice a day
has been shown to significantly improve their exercise capacity. Arginine
supplementation has also been reported to result in 70% reduction in angina
attacks in another study.
L-arginine works by stimulating the production and release of NO. However,
L-arginine may have separate anti-atherogenic independent in of its role
in the enzymatic formation of NO. For example, l-arginine itself may have
antioxidant activity. It has been shown to inhibit the oxidation of unoxidized
low density lipoprotein (LDL) to oxidized LDL (oxl LDL). The oxidation of
LDL to oxl-LDL is believed to be a critical early step in the formation
of arthrosclerosis.
L-arginine may also independently have a scavenger effect in sweeping up
super oxide anions and hydrogen peroxide as well as reducing the peroxidation
of lipid. Furthermore, it has been shown to have immunomodulatory activities.
Supplementation of this amino acid in breast cancer has been shown to increase
the quantity and cytotoxicity of natural killer (NK) and Lymphokine-activated-killer
(LAK) cells. The exact mechanism is not clear and but it has been shown
however that l-arginine is a precursor in the synthesis of tetrapeptide
tuftsiin, which itself appears to have immunomodulartory activities.
Arginine is an excellent helper when it comes to wound repair. This may
be due to its precursor role in the formation of l-ornthine, and ultimately
l-proline. L-proline in conjunction with l-lysine and vitamin C are the
key elements in collagen biosynthesis. Collagen is the main ingredient in
tissue healing and scar tissue formation. Arginine participates in the maintenance
of muscle and lean tissue in the body.
Arginine, in high dose, promotes an increase in the body’s production of
insulin like growth factor (a measure of human growth hormone). Its use,
together with lysine, ornithine and glutamine, is one way to stimulate the
body’s release of growth hormone.
Interestingly, l-arginine has also been shown to increase sperm counts.
In one early study, 178 men with oligospermia were given 4g of l-arginine
daily. Severe oligospermia was diagnosed in 93 of these subjects and 100%
increased in sperm count was found in 42 cases, resulting in 15 pregnancies.
Studies have also shown that l-arginine is beneficial for people with kidney
diseases as well as interstitial cystitis. It improves kidney function in
diabetic animal models and it helps promote renal vasodilatation.
In summary, arginine is a very versatile amino acid. Many of its function
is just started to be explored. NO produced
in the body from the intake of arginine can play a major role in anti-atherogenic
activity. NO inhibits mononuclear cell adhesion, platelet aggregation,
proliferation of vascular smooth muscle, and production of some reactive
oxygen species, such as super oxide anions. It is a promoter of endothelium
dependant dilation and is able to normalize high blood pressure. In other
words, it relaxes the blood vessel and reduces the arterial stiffness. It
increases sperm count, boost immune function, and enhances male sexual disorders,
restores protein balance and speeds wound healing.
Arginine Dosage
Arginine is a non-toxic compound. Dosage
of up to 15 grams a day has been well tolerated. The most common
adverse reaction to high doses (15-30 grams a day) are nausea, abdominal
cramps, and diarrhea, and scaling back the dosage will eliminate the problem.
Because high dose and long term use of arginine can lead to an increase
in growth hormones, pregnant and nursing mothers should refrain from high
doses of arginine supplementation. The use of arginine in the cardio vascular
and erectile dysfunction setting has been very promising. While no supplementation
can work 100% of the time, most people do experience some improvement when
dosed properly. For cardio vascular health
doses, 2-15 grams a day should be used in divided doses. To help
sperm count, doses of 10-20 grams a day have been used. For erectile dysfunction,
daily doses of 5 grams a day have been used. For interstitial cystitis,
1 to 4 grams a day is commonly used.
To avoid arginine’s risk of promoting
free radical oxidation, supplementation should always be accompanied by
antioxidants including vitamin C, ascobyl palmitate, lysine, proline, small
amount of co-enzyme Q10, and lipoic acid and other antioxidants. This
is especially important for those with inflammatory problems such as arthritis
as excess NO can stimulate an inflammatory response. If the immune enhancing
properties of arginine are desired, always add proline and lysine. Because
some infectious pathogen may actually use arginine as a fuel, lysine should
be added to help neutralize any virus attack. Children under 18 should not
take arginine for any extended period of time.
Anyone concern with cardiovascular health, and especially with normalization
of blood pressure, should consider nutritional supplementation of arginine
in conjunction with other synergistic and pre-cautionary co-factors mentioned
above. Arginine dosage ranges from 2-5 grams a day. Those who have a
history of low blood pressure should be careful as NO may further lowers
the pressure.

Cellular Energy Metbaolism
Mitochondria are the energy factories of the cell. The energy currency they
produce is ATP. Generation of ATP is therefore vital to cellular process.
Coenzyme Q10, or ubiquinone, is a vital component in the ATP-generating
process. It acts as an electron acceptor/proton donor; hence its presence
in the body is fundamental to the support of cellular life. It is omnipresent
in body tissues.
With advance technology, the cellular metabolism rate can now be measured.
Unfortunately, its commercial use is not wide spread because laboratory
test are very expensive. Fortunately, there is already enough scientific
research that commands us to do all we can to enhance cellular energy generation
regardless. When more energy can be generated by the heart with the same
fuel, the heart does not have to work as hard. In laymen’s term, you don’t
need to get a fancy tune up for your car to know that regular use of better
grade gasoline can help to have a cleaner and more efficient engine.
The following are proven nutrients that promote cellular metabolism and
should be taken by everyone concerned with heart health.
Coenzyme Q10 (Ubiquinone)
The body's production of CoQ10 begins to decline after age 20 to just 50%
of levels by age 70. Because the function of the heart is so dependent on
the energy produced with the help of CoQ10, CoQ10 is extremely important
for heart health. It is also important as a powerful antioxidant and a membrane
stabilizer. The range of heart conditions for which research has found
CoQ10 beneficial include (1) congestive heart failure, (2) cardiomyopathies,
(3) arrhythmias, (4) angina, when there is a lack of oxygen, and (5) muscular
dystrophy.
Individuals with cardiac disorders have been identified as having abnormally
low levels of CoQ10. Numerous long-term studies have been conducted to ascertain
the efficacy of CoQ10. These studies indicate that there is a statistically
significant improvement in the condition of those patients with myocardial
dysfunctions such as ischemic cardio-myopathy or congestive heart failure
when they take CoQ10. In an 8-year study of 424 patients with cardiac dysfunction,
58% improved by one functional class, 28% by two classes, and 1.2% by three
classes. Further, overall medication requirements dropped, with 43% of the
patients discontinuing between one and three drugs. Only 6% were required
to add one drug. In another study on 40 patients undergoing elective coronary
artery bypass surgery, pretreatment with CoQ10 at 150mg/day for seven days
served as a protection against oxidative compounds.
CoQ10 also plays a vital role as an antioxidant in cellular membranes and
plasma lipoproteins. It is present in all plasma membranes and in LDL-cholesterols.
Studies illustrate CoQ10's protective action against the oxidative modification
that makes LDL-cholesterol atherogenic. In its reduced form, ubiquinol,
CoQ10 also functions as a chain-breaking antioxidant and is believed to
regenerate Vitamin E.
You can get CoQ10 from your diet, although the amount of food intake is
insubstantial. For example, one pound of sardines or 2.5 pounds of peanuts
provide 30 mg of CoQ10.
Working synergistically with CoQ10 are two endogenous antioxidants that
enhance mitochondrial function and reduce free radical damage - L-Carnitine
and Lipoic Acid.
L-Carnitine and Lipoic Acid
The ability of the cell to utilize fatty acids as a source of fuel is essential
for optimizing the production of ATP by mitochondria in cardiac cells to
keep the heart properly functioning. L-carnitine assists in this transportation
process by bringing fatty acids from the extra-cellular space into the mitochondria.
In one double blind trial, 500 mg per day of a modified form of carnitine
called propionyl-L-carnitine lead to a 26% increase in exercise capacity
after six months.
Lipoic Acid is both a water- and fat-soluble antioxidant. It neutralizes
free radicals in both the fatty and watery regions of cells, in contrast
to Vitamin C, which is water soluble, and Vitamin E, which is fat soluble.
Lipoic acid is therefore called the "universal antioxidant". It
has the ability to recycle both Vitamin C and E in our body. It helps break
down sugars so that energy can be produced from them through cellular respiration.
In addition to serving as the bulb of the body's antioxidant network, lipoic
acid is the only antioxidant that can boost the level of intracellular glutathione,
a cellular antioxidant of tremendous importance. Glutathione is a water-soluble
antioxidant and is essential for the optimum functioning of the immune system.
Nutritional Supplement Consideration:
Coenzyme Q10: 30 - 300 mg ( less is needed
if synergistic agents are added such as peperine extract that can enhance
CoQ10 activities by up to 25%)
L-Carnitine: 300 - 2,000 mg
Lipoic Acid: 75 - 300 mg
C-reactive protein (CRP) is a protein released into the bloodstream any
time there is active inflammation in the body, such as infections and arthritis.
CRP is conventionally regarded as the first-line of defense of the immune
system against invading pathogens by eliminating them through the inflammatory
response.
Recent studies have shown, however, that CRP is much more than that. In a study published in the New England Journal of Medicine, researchers analyzed over 20,000 blood samples taken from women enrolled in the Women's Health Study, a long-term study that enrolled and followed apparently healthy women for a number of years. It was found that an elevated blood level of CRP is strongly predictive of future cardiovascular events such as heart attack and stroke. In other words, CRP is an independent marker of cardiovascular risk, and may be a partial explanation for why some patients develop significant coronary artery disease despite normal cholesterol levels. In this study, women with low CRP and low cholesterol have the lowest risk, while those with high CRP and high cholesterol had very high risk. Women with either high CRP or high cholesterol also had elevated risk. Interestingly, those with high CRP but normal cholesterol apparently had a higher risk than those with normal CRP and high LDL cholesterol. CRP is a predictor of future atherosclerotic event.
CRP binds to LDL in the artery wall, creating an "oxidized LDL"
that is thought to be the cause of inflammation. The inflammation process
attracts macrophages. These macrophages then become "foam cells,"
initiating a cascade of events leading to the generation of atherosclerotic
plaques.
CRP therefore is tied into cardiovascular risk by at least two distinctive
pathways. The importance of CRP as an advance-screening tool of cardiovascular
risk cannot be ignored. In fact, it may be just as important as elevated
LDL cholesterol levels. Without measuring CRP level, many high-risk patients
would be "missed".
Fortunately, CRP is an easy and inexpensive
blood test to perform. The normal value is under 1 mg/dl.
There are no drugs or medication that can definitively
reduce CRP levels. There is suggestive evidence that both
aspirin and statin drugs can reduce CRP levels to a certain degree. However,
there are side effects accompanying the use of these drugs. Certain lifestyle
changes can also lead to a reduction in CRP levels, such as smoking, metabolic
syndrome (syndrome X), and periodontal disease (gum disease).
Fortunately, taking nutrients with anti-inflammatory
properties such as molecularly distilled fish oil high in omega 3 will help,
together with compounds such as bromalin, curcumin, cat’s claw, olive leaf,
and fibrin dissolving nutrients such as natto.
A. Omega-3 Fatty Acid
Omega-3 fatty acids provide a range of benefits and protection
for the heart and our body. In addition to reducing the risk of heart disease,
they also help prevent blood clotting, heart attacks and irregular heartbeats
that could lead to sudden cardiac death. They are anti-inflammatory, and
inflammation is a key initiator of the atherosclerotic cascade leading to
plaque formation and sudden death. Omega-3 also has anti-cancer functions,
as we shall see.
Omega-3 fatty
acids can be divided into 3 main categories -- Eicosapentaenoic Acids (EPA),
Docosahexaenoic Acids (DHA) and Alpha-Linolenic Acids; out of which EPA
and DHA have the most beneficial effects. EPA and DHA are found mainly in
fish oils while Alpha-Linolenic Acids are usually derived from plant sources
such as soybeans, canola, walnut and flaxseed.
Of all the fatty acids in the blood including saturated, monounsaturated,
and polyunsaturated, only the percentage of long chain omega-3 predicted
fewer sudden death. In a study of 11,323 recent survivors of heart attack,
1 gram of omega-3 or 300 mg of Vitamin E or both was given. The usual pharmacological
regiment and lifestyle recommendations were made. It was shown that omega-3
and not Vitamin E improved survival. After 3 months of remaining on regiment
of omega-3, patterns showed a 41% decrease in mortality, a 53% reduction
in sudden death after 4 months, and a 30% decrease in cardiovascular mortality
after 12 months. There was also a 5% decrease in triglyceride but not total
cholesterol, HDL, or LDL cholesterol.
Increasing the intake of EPA and DHA will lead to an increase of omega-3
fatty acids in tissue or cellular lipids and circulatory lipids. At the
same time, it will reduce the omega-6 fatty acids such as LA and Arachidonic
Acid (AA), which is not beneficial to our bodies.
The fatty acid shifts are particularly pronounced in the cell membrane-bound
phospholipid components. Cell membranes and their functioning, for example,
improved with reduced inflammatory response. There is also reduced platelet
aggregation and enhanced blood flow. The vasodilatory effect will increase
lumen size of vascular system. Studies have shown that fish oil concentrates
that provide EPA and DHA at intakes of up to 2-4grams a day, taken over
a few weeks, can lower various risk factors for heart disease. These effects
include an anti-thrombotic effect, lipid (triglyceride) lowering, reduced
blood and plasma viscosity, and improvements in endothelial dysfunction.
Omega-3 fatty acids accumulate to a considerable extent in various sites
including circulating blood platelets, the heart and serum phospholipid.
The accumulation of EPA and DHA in platelets leads to a decrease in platelet
adhesiveness, aggregation and an overall reduction in thrombogenicity. Antiatherogenic
effects of omega-3 fatty acids have also been shown in animal studies with
similar results. Eicosanoid formations are also influenced positively. The
eicosanoids formed via oxygenase enzymes acting on AA and EPA includes prostaglandins,
leukotrienes and thromboxanes. Both eicosanoid-dependent and eicosanoid-independent
processes mediate the benefits of omega-3 fatty acids on cardiovascular
disease. For example, the reduced blood platelet reactivity (antithrombotic
effect) with increased EPA and DHA intakes involve the reduced formation
of the proaggregatory eicosanoid known as thromboxane A2 (TxA2).
B. Curcumin
Curcumin comes from turmeric root and is an ancient
spice within the ginger family that is widely used in cooking. Its use dates
back to the time of Egyptian pharaohs more than 6,000 years ago. A tall,
stemless, perennial plant cultivated throughout the tropics, turmeric is
what gives curry its unique color and flavor.
In addition to its kitchen uses, curcumin has been used by traditional medicine
for wide variety of ailments including liver disease indigestion, urinary
tract diseases, inflamed joints, insect bites, and dermatological disorders
Although the chemical structure of curcumin was discovered in 1910, it was
only during the mid 1970s and that the potential uses of curcuminoids in
medicine began to be extensively studied. It has been shown that curcumin
has both strong anti-oxidant and anti-inflammatory properties. It’s anti-inflammatory
property help to bring curcumin into the forefront of heart disease prevention
supplements.
Inflammation results from a complex cascade of chemical
reactions in a series of actions triggered by the body's response to tissue
damage. This damage may be caused by physical traumas including various
diseases and surgery. It can also come from chronic minute free radical
damage to endothelial wall over time. Curcuminoids prevent the synthesis
of several inflammatory prostaglandins and leukotrienes. Curcuminoids inhibit
several enzymes that participate in the production of inflammatory metabolites
in the body. The natural anti-inflammatory
activity of curcuminoids is comparable in strength to steroidal drugs as
well as nonsteroidal anti-inflammatory drugs as indomethacin and phenylbutazone,
which have dangerous side effects.
In a double blind, controlled study, three groups of patients received curcumin
(400 mg), the anti-inflammatory prescription drug phenylbutazone (100 mg),
or a placebo three times daily for five consecutive days after surgery for
either a hernia condition or an accumulation of fluid in the scrotum. The
results show that curcumin was just as effective as phenylbutazone in reducing
post-operative inflammation.
Inflammation is known to be associated with increased levels of lipid peroxides
and free radicals, which are generated by the liver as well as by inflamed
tissues in the body. Animals fed curcumin showed decreased levels of lipid
peroxides and subsequent reduction in the processes of inflammation. In
one study, curcumin was shown to be eight times more powerful that vitamin
E in preventing lipid peroxidation. With decreasing oxidation of the endothelium,
more nitric oxide is produced and the arterial stiffness is lessened.
Curcumin has a similar anti-inflammatory action to aspirin. However, unlike
aspirin curcumin inhibits the production of inflammatory prostaglandins.
It does not affect the synthesis of prostacyclin, an important factor in
preventing vascular thrombosis. Compared to drugs, curcumin may therefore
be preferable for patients who are prone to vascular thrombosis and require
anti-inflammatory and/or anti-arthritic therapy.
Dosage: 50-200 mg. Since curcumin
also lowers cholesterol levels by increasing the flow of bile out of the
liver, those with biliary tract obstruction should not use curcumin.
Always take curcumin with food.
C. Bromalin
Discovered in 1957, bromelain is the name of a group of protein-digesting,
or proteolytic enzymes that are found in the pineapple plant. It is usually
distinguished either as the fruit bromelain or stem bromelain, depending
on the source. All commercially available bromelain comes from the stem.
Bromelain is a natural blood thinner and an anti-inflammatory agent. It
works by breaking down fibrin, a blood clotting protein that can prevent
healthy circulation and tissues from draining properly. Bromelain also blocks
the production of compounds that cause pain and swelling.
Bromelain, when taken orally, is absorbed through the gastro-intestinal
tract, with up to 40% absorption. Because it comes from a natural source,
a variety of destinations have been used to indicate the potency and activity
of this compound. Research studies vary in destinations utilized. The most
common unit includes RORER units (RU), gelatin dissolving units (GDU), and
milk clotting units (MCU). One gram of bromelain standardized to 2000MCU
is the equivalent of 1g of 200GDU of activity or 8g of 100,000RU of activity.
Bromelain’s cardio benefit properties were first discovered in 1972. It
was found that it has the ability to prevent aggregation of blood platelets.
In a study, bromelain was administered to 20 volunteers with a history of
heart attack or stroke and have a high platelet aggregation values. Bromelain
was shown to decrease blood aggregation in 17 of the subjects and normalize
values in 8 of the 9 subjects who previously had high aggregation values.
Bromelain is an effective fibrinolytic agent. In high doses, there is a
correspondent reduction in the serum fibrinogen level shown in rats, with
both prothrombin time (PT) and activated partial thromboplastin time (APTT)
markedly prolonged. With the presence of bromelain, the conversion of plasminogens
to plasma is enhanced. The spread of the coagulation process is limited
due to fibrin degradation. In addition to the platelet pathway, bromelain
also has direct as well as indirect action involving other enzyme systems
and exerts its anti-inflammatory effects. Experimental studies using bromelain
has shown its ability suppress inflammation is similar to that of prednisone.
This is due to its ability to selectively modulate the biosynthesis of thromboxanes
and prostacyclin. These 2 groups of prostaglandins with opposing actions
ultimately influence the activation of cyclic-3,5-adenosine (cAMP), an important
cell growth modulating compound.
Dosage: 1,000 to 6,000 mg with potency
of 3,000 GDU/gram.
Of the four commonly measured lipid markers (total cholesterol, HDL cholesterol,
LDL cholesterol, and triglyceride), triglyceride
is the most underappreciated and perhaps the most important.
Reason – we don’t know enough about triglyceride metabolism within the body.
Triglycerides are etherified fatty oils that form the core of chylomicrons
and VLDL cholesterol. Triglycerides and cholesterol both measure the total
amount of lipoproteins in the serum. The associated cardiovascular disease
risk prediction offered by triglycerides and cholesterol by themselves is
44%, but when coupled with low Vitamin A and E, looking at the ratio of
(cholesterol + triglycerides)/ (Vitamin A & E), the risk predictive
power goes to 85% accuracy.
A diet high in saturated fats, such as red meat and a diet high in simple
carbohydrates and starchy food (such as sugar, rice, and wheat respectively)
raise serum triglyceride drastically. Only 20% of the ingested sugar load
can be burned or stored as glycogen at any one meal. The remainder 80% will
be converted to triglyceride that can contribute to the buildup of acidity,
or stored as fat deposits.
Elevated blood levels of triglycerides, but not cholesterol, have been associated
with an impaired fibrinolytic system, leading to atherothrombotic stroke
and transient ischemic attacks. It is a powerful predictor of myocardial
infarction.
The role of triglyceride has is now only being studied in depth. It is clear
that triglyceride is in fact the key link that connects carbohydrates to
obesity, and not dietary fats or dietary cholesterol. The dominant cause
of high triglyceride is high carbohydrates and not fats. In other words,
a high triglyceride level is almost synonymous
to a high carbohydrate diet and not a high fatty diet.
Since triglyceride
elevation is almost universally related to dietary intake of sugar (including
grains), high triglycerides is one of the most easy and straightforward
problems to correct with proper diet alone. The decline is dramatic and
in a matter of weeks if the proper low glycemic, low grain anti-aging diet
is followed.
While a normal triglyceride level can be up to 160mg/dl, the appropriate
goal for anyone serious about optimum health should target the triglyceride
to be no higher than 100 mg/dl. A triglyceride count of 100 or more increased
the relative risk of a new cardiovascular event by 50% and reduced the chance
of surviving a subsequent heart attack.
Medications are available to lower triglyceride level, but this is seldom
necessary as long as a strict no grain diet is adhered to.
Start with eliminating all grain products from the evening meal.
This includes wheat, rye, barley, potato, bread, and rice. It is usually
difficult in the beginning and carbohydrate cravings may be experienced.
This is quite common because the body is already addicted after years of
taking in grains. If this happens, cut back by only 30 %for 60 days and
allow your body to have a transition. If you feel hungry 1-2 hours after
a meal, eat a handful of raw nuts such as almonds or walnut that has been
presoaked for at least 6 hours in room temperature water.
As the body slowly gets used to the reduced grains intake at dinner,
also reduce grains intake at lunch. Substitute with more above the ground
vegetables, eggs (raw is best, and try not to cook the yolk too well), and
unroasted nuts. Oils are acceptable as long they have not been exposed to
high heat. Use virgin olive oil for salads and light stir fry, butter for
high heat frying, and coconut oil for deep-frying (which should be kept
to a minimum). As usual, no desserts after dinner, and reduce snacks before
bedtime. All refined carbohydrates such as cookies, ice cream, and chips
should be avoided. Follow the above, and the triglycerides level will come
down drastically in a matter of weeks. As
the triglycerides normalize, the total cholesterol will reduce automatically,
and the total cholesterol to HDL cholesterol ratio will automatically improve.
For those unable to follow no grain diet, taking a natural compound called
panthethine at 600-1200 mg a day will effectively lower triglyceride as
well without any side effects. Other nutritional supplementation that can
help lowering triglyceride includes L-carnitine (500-3,000mg), chromium
polynicotinate (400 to 1,200 mcg), venadyl sulfate (15-30mg), EPA/DHA (500
–5,000 mg)
8.
Total cholesterol / HDL Cholesterol ratio.
Cholesterol is a key macronutrient the body cannot do without. It is a precursor
to all the steroid hormones in our body, including pregnenolone, DHEA, estrogen,
progesterone, testosterone, and cortisol. Too low a total cholesterol level
(under 150mg/dl) have been associated with cancer and brain function impairment.
The ideal total cholesterol level should be around 200 mg/dl.
HDL is the “good” cholesterol. It is a carrier of “bad” LDL and oxidized-LDL
cholesterol from the blood stream back to the liver. The higher the HDL
level, the better. It is best to have HDL level over 45 mg/dl. Anything
under 30 mg/dl is considered a risk factor by itself. Taking nutrients such
as fish oil can increase HDL. Exercise has shown to increase HDL as well.
It is not unusual for those in good health with HDL level of close to 100
mg/dl.
Total cholesterol in and of itself alone as rudimentary tool in cardiovascular
health predictive value, and HDL in and of itself is a reasonable marker.
Taken together as a ratio, their predictive
value increases significantly. In fact, total cholesterol of
over 200 mg/dl, as long as it is accompanied with high HDL cholesterol with
resulting low total cholesterol to HDL cholesterol ratio of less than 3.5,
requires no therapeutic intervention at all.
The ideal Total cholesterol / HDL cholesterol
ratio should be 3.5 or less, and preferably under 2.5.
9.LDL
cholesterol
Low-density lipoprotein (LDL) is the major cholesterol carrier in the blood.
If too much LDL cholesterol circulates in the blood, it can get oxidized.
It is the oxidized form of this that triggers a series of inflammatory reaction
in the blood stream, providing a trigger for heart attack and stroke. It
is therefore also called the “bad” cholesterol for a good reason. Oxidized
LDL slowly builds up in the walls of the arteries feeding the heart and
brain. Together with other substances it can form plaque.
A high level of LDL cholesterol (160 mg/dl
and above) reflects an increased risk of heart disease. If you have heart
disease, your LDL cholesterol should be less than 100 mg/dl.
One would think that its measurement in the blood should be highly complex.
In reality, LDL is not even measured in the traditional lipid panel blood
test. Out of the five tradition markers reported in the lipid panel,
LDL is the only marker that is a calculated
number and not a measured number.
Here is the formula:
LDL cholesterol = total cholesterol –
HDL cholesterol – (Triglyceride /5).
You can accurately decide the LDL cholesterol level as long as the total
cholesterol, HDL cholesterol and triglyceride level is available. However,
if the triglyceride level exceeds 350 mg/dl, the total LDL level will not
be accurate based on the calculation and therefore cannot be
relied upon. In this case, the actual measured LDL level should be obtained
from the laboratory.
The single focus on LDL lowering has been a pharmaceutical industry darling
for the past 20 years, and for good reasons. Worldwide sale of these drugs
continues to climb at a record pace. There is little doubt that drugs
can reduce LDL cholesterol aggressively. These drugs are the synthetically
derived HMG-CoA reductase inhibitors such as Iovastatin, pravastatin, and
simvastatin. They are collectively called "statin" drugs. By inhibiting
the production of HMG-CoA reductase, cholesterol production in the liver
is reduced. Based on the latest “scientific” recommendation to bring
down the blood LDL cholesterol level to 70 mg/dl, 40 million Americans will
qualify to enter this drug based cholesterol lowering program. In America
alone, over 40 million prescriptions were written yearly for cholesterol
lowering medications. It is estimated that in the coming years, 50% of American
adults will be on this serious drug.
While statin drugs are effective in lowering
LDL cholesterol, they have serious side effects. In August 2001,
however, German Pharmaceutical giant Bayer AG withdrew the cholesterol-lowering
statin drug Baycol from the market because it was linked to 31 deaths. Moreover,
deaths occurred at the manufacturer's recommended initial dose (0.4 mg/day)
as well as at the highest dose (0.8 mg/day). The majority of deaths occurred
in elderly patients and more often in women. Statin drugs can cause severe
muscle weakness and pain even at low doses. Using the proper dosage is clearly
an important if not critical part any drug based lipid-lowering program.
Recent studies have also shown that high
dose (80 mg) of a popular statin drug called Zocor does no better than low
dose (40mg) in the prevention of heart attack in high risk patients.
There are other statin drugs on the market, such as
Lipitor. Like Baycol, these drugs are linked to the same rare muscle weakness,
known as myositis, which occurs in about 1 in 1,000 statin users. Myositis
occasionally progresses to rhabdomyosis -- a complete breakdown of muscle
cells that can lead to kidney failure and death. Statin drugs also cause
cognitive impairment and memory loss. It has been well known that these
drugs routinely cause cancer in laboratory animals. Some experts
believe that pravastatin (Pravachol) and fluvastatin (Lescol) may have less
potential for these deadly drug interactions. The data at this time is not
sufficient to declare one statin drug safer or more dangerous than the others.
It will be years before we know the full side effects of statin drugs.
Statin drugs also inhibits the intrinsic biosynthesis of Coenzyme Q10 (CoQ10),
a central compound in the mitochondrial respiratory chain. CoQ10 is indispensable
for optimum cardiac function. Reduction of CoQ10 constitutes new risk of
cardiac disease, especially for those whose cardiac function is already
compromised, such as those with congestive heart failure or cardiomyopathy.
While cholesterol-lowering drugs may lead to fewer heart attacks, the mechanism
of action may not be related to a lowered blood cholesterol level only.
Statin drugs have been shown to reduce inflammatory response in the
endothelium. It may well be that reduction accounts for the cardiac benefit
effect. The suppression of cholesterol manufacturing in the liver leading
to cholesterol lowering levels may be a less important and a secondary benefit.
There is also a desirable effect of raising nitric oxide levels.
It is interesting to note that there are natural compounds that have anti-inflammatory
and raising nitric oxide level properties without side effects.
The optimum level of LDL is under 100 mg/dl, and over 160 mg/dl is considered
high. While
LDL does have predictive value in terms of cardiovascular disease risk,
it should, like others, be view as part of an overall picture and not a
stand-alone key indicator. This has not been the case, sad to say.
It is important to note that as the endothelium
heals, the LDL level will naturally normalized without the use of drugs.
Because endothelium healing takes some time, immediate drop in LDL level
will not and should not be expected. For those requiring immediate normalization
without drugs, the following should be considered: : panthethine (300-900
mg), panthothenic acid ( 600-1,500 mg), chromium polynicotinate (300 to
600 mcg), ascorbic acid (1000 to 3000 mg), guccolipid (50-200 mg) and polycosinol
( 5-20 mg).
10.Total
cholesterol
Thanks to mass-market commercialization, total cholesterol testing is now
easily and widely available. A simple pinprick and a drop of blood on a
test strip can offer almost instant results in a matter of minutes.
It is important to note that the total cholesterol is reported based on
the following formula in the laboratory:
Total cholesterol = HDL cholesterol +
LDL Cholesterol + (triglyceride / 5).
Looking at the formula, one can easily see that if LDL, HDL or triglyceride
is high, then the total cholesterol level has to be high.
If the total cholesterol is high
and is due to high HDL cholesterol, there is no cause for alarm.
Any attempt to lower total cholesterol in such case is in fact
unwarranted. HDL cholesterol should be as high as possible.
If the total cholesterol level is high primarily
due to a high LDL or triglyceride level, then a cholesterol-lowering program
should be considered. However, the therapeutic pathway to lowering LDL (with
statin drugs or nutritional supplementation) is different from that of triglyceride
lowering (by diet, drugs, and nutritional supplements). It is imperative
that a critical distinction be made to determine if the root cause of the
high cholesterol is due to high LDL or high triglyceride prior to initiation
to therapeutic measures.
Specifically, if the high total cholesterol is due to a high triglyceride
level, then a no grain dietary approach is best, and using drugs to normalize
triglyceride without dietary change is a band-aid approach. A no grain diet
will be able to universally lower triglyceride level unless it is a familial
condition. Many well intentioned but misguided
physicians embark on a program of cholesterol reduction only to find failure
at the end of the tunnel. Patients are subjected to ever-higher
doses of statin drugs unnecessarily when all it needs is simple dietary
change if the main cause of high cholesterol is due to triglyceride overload.
Traditionally, a total cholesterol value
of less than 200 mg/dl is considered desirable, while the value of over
240 mg/dl is considered high. By now it should be obvious that
simply looking at the total cholesterol
alone without considering HDL, LDL, or triglyceride will not give a true
picture and is obviously incomplete. In this respect, it can be seen that
the total cholesterol number on its own is of little significant clinical
value.
Summary
Modern science has ushered in a series of advanced markers of cardiovascular
health that only 20 years ago was not available. The traditional dependency
on cholesterol as the key marker needs to be downgraded. Far
more sensitive markers including Lp(a), homocysteine, C reactive protein,
arterial stiffness, and fibrinogen levels are easily obtained, and reference
ranges have been well established. Currently, there are no effective drug
base programs to normalize these markers, and the use of these markers is
therefore not widespread.
The use of natural nutritional supplementation
to normalize these markers have been well studied and their effectiveness
not in doubt. They should represent the first line defense for those who
are at risk or have damaged cardiovascular system. Optimization
with a complete nutritional program focused on the heart will not only reduce
risk, but in fact in many cases, can reverse existing damage without the
side effects often seen by medications.
For optimum heart disease prevention,
the following basic comprehensive nutritional cocktail should be considered
and taken on a daily basis. There is no one nutrient that is
more important than others, because each has a part to play and is important
is its own right. Do not simply pick and choose.
The
advantage of having a blended nutritional cocktail is that a much lower
dose of each nutrient is required due to their combined synergistic effect
without sacrificing therapeutic efficacy. At the same time,
all the key cardiovascular pathway markers are covered. Because endothelium
healing takes time, patience is required. While some people notice a
significant improvement in heart health in as little as a few weeks, expect
3 to 6 months for cellular nutrition to do its work is best. The
key is to take the entire cocktail blend in proper dosage for long enough
time to allow the body to heal itself. Because each person is
different and the degree of existing damage varies, be prepared to allow
up to 6 –12 months in selected cases. The key to apply the right dose, and
consulting a health care professional experienced in this area is highly
recommended.
Alpha Lipoic Acid –75 mg
Coenzyme Q10 –10 mg ( as long as enhancing agents such as peperine is included)
Curcumin – 20 mg
Folic Acid – 150 mcg
Fish Oil – 500 mg
Bromelain - 1000 mg (3,000 GDU /gram)
Citrus Bioflavonoids - 30 –100 mg
Nattokinase – 25 mg (20,000 FU/gram)
Magnesium - 90 mg
L-arginine - 600 mg
L- carnitine - 100 mg
L-lysine - 300 mg
L- proline -15 mg
Vitamin B5 (calcium pantothenate) - 70 mg
Vitamin C including ascobyl palmitate- 500 mg
Vitamin E - 75 I.U.
Other nutrients that can be helpful include hawthorne, n-acetyl cysteine,
pine bark extract, ornithine, glutamine, malic acid, citrus bioflavonoids,
peperine extract.
If there are significant cardiac health
challenges such as high blood pressure, calcium plaques, or arrhythmias
are present, the dosage should be increased substantially by up to
5 to 20 times of each nutrient, depending on the situation.
