Know & Control Cholesterol In a different Perspective |
High total
serum cholesterol and LDL cholesterol are significant risk factors of
cardiovascular disease. 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.
Developed countries have shown a decrease in dietary
fat and cholesterol consumption in recent years. This is largely the result
of on-going massive public health campaign advocating a low fat, high
carbohydrate diet as ideal to bring down blood cholesterol level to prevent
arthrosclerosis. Despite this effort, the
number of people with elevated blood cholesterol continues to increase.
Obviously there are other causative factors
that have not being addressed. In America alone, over 40 million
prescription was written yearly for cholesterol lowering medications.
After decades of research, nutritionists are still debated on the etiology of
high cholesterol and the best way to bring it down. Let us take a closer look.
Cholesterol Basics
Cholesterol is a waxy substance consisting of
fats (lipids) and proteins. It is one of the macro-nutrients necessary for
life. Cholesterol is made in the liver and is carried in the blood on carrier
molecules called lipoproteins. The main lipoproteins categories are
very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and
high-density-lipoprotein (HDL). Once bound to the carrier HDL, the cholesterol
is known as HDL cholesterol. HDL in effect transports fat from the cell to the
liver. When the HDL cholesterol level is high, it is more cardio protective.
Therefore, HDL cholesterol is considered "good " cholesterol. LDL is the
carrier of oxidized cholesterol as LDL cholesterol from the liver to cell.
Elevated LDL cholesterol is directly correlated with increased cardiovascular
risk. LDL cholesterol is therefore called the "bad" cholesterol.
Cholesterol, when unoxidized, is an
antioxidant and free radical scavenger in its naturally occurring state.
In fact, unoxidized cholesterol guards the cell membranes' phospholipids from
free radical damage and protect it against atherosclerosis, cancer, and other
free radical attack. Also, cholesterol is a predecessor to many steroid hormones
and vitamin D. It is produced at the liver at the rate of 3,000 to 4,000 mg a
day.
Cholesterol and
Free Radical Activity
While the exact mechanism of how cholesterol affects our body is
still under intense investigation, it is clear that the unified theory of free
radical damage caused by unhealthy foods such as processed fat and oxidized
cholesterol is the most likely mechanism. Free Radical damage to our blood
vessels is one of the primary causes of atherosclerosis.
The most important cause of free radical
pathology is the excessive dietary fat consisting of processed
poly-unsaturated fatty acid (PUFA) and
trans fat (frequently used in fried foods, margarine, cooking oil, and
oxidized cholesterol from commercially prepared foods). In the event
that dietary fat and oil is retrieved from fresh, whole, and unprocessed foods,
no lipid peroxidation will take place and the cell membrane will remain healthy
in a normal cis-configuration without any free radical damage.
One theory advanced by the late Nobel laureate Dr. Linus Pauling, together with
his research cohort Dr. Matthias Rath, is that the total serum cholesterol is
really an indicator of the amount of free radical damage in the body. Our body
maintains an optimum level of total cholesterol level as well as a delicate
balance among its subcomponents. A negative feedback mechanism exists within the
body that decreases the rate of endogenous synthesis when the dietary intake
exceeds what is needed. The total circulating cholesterol remains relatively
constant between 170-200 mg/dl for the normal adult.
The higher the free radical level, the higher the
body needs to produce cholesterol internally from the liver to act as an
antioxidant and free radical scavenger. Cholesterol level is
therefore an indicator of free radical activities in the body.
Free radicals are not all bad. Some of them are definitely necessary to
protect us against cancer cells and infections. In fact, a low total cholesterol
level (below 150 mg/dl) has been linked with an increased risk of cancer and
stroke. Too many free radicals, on the other hand, is detrimental to our health.
Cholesterol in its natural state is therefore
actually good for us. During commercialization, lipid (including fat
and cholesterol) peroxidation takes place as soon as fats and oils are extracted
from the foods in which they naturally occur. This commercialization process is
sped up by metallic ions, particularly iron and copper. Extensive lipid
peroxidation can occur without an apparent stale or flavor, like in peanut
butter, the making of salad and cooking oil, and also in so-called cold-pressed
oils. During the processing of PUFAs to make
cooking oil, rapid peroxidation can take place and free radicals are released.
This process is accelerated by heat, atmospheric oxygen, light, and trace
amounts of unbound metallic elements.
Oxidized cholesterol is a free radical
generator. It is attached
particularly to low-density lipoproteins as LDL cholesterol as it goes from the
liver to the cell. Hamburgers and other cooked and processed foods
contain animal fats that are usually high in oxidized cholesterol when cooked.
Foods cooked in animal fat and fried in processed PUFA (such as corn oil) also
have high oxidized-cholesterol content. As a result, the higher the LDL
cholesterol level, the higher the risk of cardiovascular disease. 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.
One of the most important causes of free radical pathology is the excessive
dietary fat consisting of processed PUFA or trans fat frequently used in
fried foods, margarine, and cooking oil. In the event that dietary fat and oil
is retrieved from fresh, whole, and unprocessed food, no peroxidation will take
place and cell membrane will remain healthy in a normal cis-configuration
without any free radical damage. Studies have
shown that 20% of dietary calories as commercially available fat will not
surpass the control threshold of endogenous free radical protection.
Unfortunately, the current contribution from such commercially processed fat to
our diet exceeds 40 percent.
Lipoprotein(a)
Some of the natural cholesterol produced by the liver in response to free
radical damage is converted into LDL cholesterol and its relative lipoprotein
(a) (Lp (a)). 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 an additional adhesive protein. Lp(a) is also made in
the liver and transported to the cell. Studies have 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. Lp(a) level should be part of a routine blood
screening test for cardiovascular disease risk.
Lp(a), according to Drs. Pauling and Rath, is the body's way of repairing its
damaged vessel wall that has micro leakages caused at least in part by free
radical damage and vitamin deficiencies (more specifically vitamin C)
Humans do not make any endogenous vitamin C
and have no self-repair mechanism of the vascular system. Lp(a) is used by the
body as a surrogate vitamin C, so to say. Lp(a), unfortunately, has a sticky
characteristic and adheres to each other, forming an atherosclerotic plaque over
time. The body, at the interim, is unaware. As long as the damage persists due
to free radical presence (either from improper diet, aging, pollution, lack of
vitamins, or toxins), the body responds by making more cholesterol endogenously
in the liver, feeding a viscous cycle of ever increasing Lp(a).
Cholesterol and
Cardiovascular Disease
The notion that total blood cholesterol level alone is the key determinant of
cardiovascular heath should be dispelled.
Polar bears, for example, maintain total blood cholesterol of over 400 mg/dl and
they seldom develop heart attacks. There is obviously a lot more to
learn about cholesterol and its link to cardiovascular disease that we currently
know.
It is proven that single focused dietary
strategy of lowering dietary cholesterol does not reduce coronary heart disease
risks. To make matters worse, "low-fat,
high carbohydrate" diets are often high in the wrong type of carbohydrate.
Instead of taking in complex, paleo type carbohydrates such as green leafy
vegetables of low glycemic index, the ignorant consumer often ends up consuming
carbohydrates of high glycemic index such as pasta, soda, processed foods, and
fast foods. These types of food are rich in sugar and starch (carbohydrate).
They actually lower the important "good" HDL cholesterol. A low HDL cholesterol
level is inversely proportional to the cardiovascular disease risk. It
should be remembered that cholesterol and fat are concentrated sources of
calories and can lead to obesity if too much is consumed.
In the Framingham study for example, men and women consumed an average
cholesterol intake of 700 mg and 500 mg per day respectively were studied (one
egg provides 200 mg). The average serum concentration of cholesterol for men and
women with higher than average cholesterol intake were found to be 237 and 245
mg/dl respectively. Subjects with lower than average intakes were found to be
237 and 241 mg/dl. The difference is statistically insignificant. Statistically,
studies have shown that people who consume 4
eggs per week (one egg provides 200mg cholesterol) actually have average serum
cholesterol (193 mg/dl) same than 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.
What is
"Normal" Cholesterol Level?
A low total serum cholesterol level (under 150
mg/dl) is undesirable for the healthy person. It is very difficult to
lower cholesterol only without other types of fats because they are often found
intermingled with each other in food. While saturated fatty acid (SFA) from
animal and dairy products is not subject to lipid peroxidation, all animal fats
contain some PUFA and cholesterol, both of which undergo auto-oxidation. Those
who are serious in reducing total serum cholesterol level should refrain from
intake of lipid peroxide-containing fats (trans fat such as margarine) with
resulting reduction of free radical pathology. Like trans fat, oxidized
cholesterol should be limited as much as possible.
A low fat diet may actually bring harm to health.
The correct way is to discern the right type of
fat and cholesterol to take and those to avoid.
The overall fat intake as a percentage of dietary calories should not fall below
25-30%. One should have plenty of "good"
mono-unsaturated fatty acids (MUFA) like olive oil, seeds, nuts, and
cold-water fish that have high
omega-3 fatty acid (N3) content.
Saturated fat is necessary for good health. It should come from free-range
poultry or beef, and organic eggs. It is very important to avoid "bad" trans
fat, like margarine and fried foods. Moreover, the use of processed PUFA such as
corn, safflower or sunflower oil should be restricted.
The optimum level of blood cholesterol should
be at the upper end of normal around 200 mg/dl.
Cholesterol Lowering Drugs
A class of drugs used to aggressively treat elevated LDL levels is 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. These are among the most potent
lipid-lowering agents available. To compensate for the resulting reduction of
cholesterol production, the liver increases absorption of LDL cholesterol,
further contributing to an overall reduction of LDL cholesterol levels.
While statin drugs are effective in lowering
LDL cholesterol, they have serious side effects. For years, the
public was led to believe that the wonders of statin drugs not only in lowered
cholesterol but possessed other health benefits as well. Millions of statin
prescriptions are written yearly in the United States alone.
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.
There are other statin drugs on the market, such as Lipitor (the best seller).
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 rhabdomyolysis -- a complete breakdown of muscle
cells that can lead to kidney failure and death. Some experts believe that
pravastatin (Pravachol) and fluvastatin (Lescol) may have less potential for
this deadly drug interactions. The data at this time are not sufficient to
declare one statin drug safer or more dangerous than the others.
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 compromised, such as those with congestive
heart failure or cardiomyopathy.
Furthermore, statin drugs have been linked to various forms of cancer in
laboratory animals. It will be years before we know the full side effects of
statin drugs.
Using statin drugs on a short-term basis to
normalize blood cholesterol is a reasonable alternative if a drug-free approach
fails. Anyone on long term statin type cholesterol lowering drug would be wise
to get regular checkups, especially on liver function.
Diet Cholesterol
and Blood Cholesterol
The trend to reduce serum total and LDL cholesterol started in the past two
decades when studies linked high dietary saturated fat intake to increased serum
cholesterol level. Furthermore, studies have convincing shown that a high LDL
cholesterol level is a definite risk factor and increases chances of
cardiovascular disease. Furthermore, cholesterol lowering statin drugs such as
Lipitor is effective to reduce LDL cholesterol. The solution therefore appears
simple - reduce dietary cholesterol on the presumption that high dietary
cholesterol leads to high LDL cholesterol. If that fails, prescribe
cholesterol-lowering medication.
The reality is that studies have shown that a
diet high in cholesterol will not
lead to high blood cholesterol if the subject is healthy. Blood
cholesterol level only increases by 3 mg/dl after ingestion of one egg day for a
continuous period of 6 weeks (one egg contains about 230 mg of cholesterol) in
repeated studies. Clearly, dietary
cholesterol is not the main culprit.
Sugar and
Cholesterol
Sugar consumption has been increasing for the past 100 years and this upward
trend remains unabated. Increased rates of
cardiovascular disease have a direct correlation to the increase in sugar intake
and not fat and cholesterol intake.
Sugar includes grains such as wheat and rice. Also included are starchy
underground vegetables such as potato, yam and carrot that convert quickly into
sugar once inside the body.
High sugar intake is linked to an increased risk of heart disease.
Simple sugars are the primary source of high
triglycerides, a type of blood fat, and very low-density lipoproteins (LDL),
which are an independent risk factor for atherosclerosis. Sugar
lowers good HDL cholesterol and raises bad LDL cholesterol and blood pressure
levels. It is estimated that a high sugar intake may account for as many as
150,000 premature deaths from heart disease in the US each year.
Sugar increases triglyceride storage and
cellular oxidative damage. This assaults the vascular wall, leading
to micro-leakages in the endothelial wall of blood vessels, leading to the
self-repair mechanism of cholesterol and lipoprotein (a) production described
above. Sugar is therefore a significant contributory factor of oxidative stress.
Simple logic dictates that reduction of sugar
intake will reduce oxidative stress. This in turn will reduce cholesterol
production from the liver.
Studies have been conducted to support this. In one research trial, 18 male
subjects received normal food followed by a rigorously specified diet in which
protein and carbohydrate requirements were met by amino acids, essential fat,
and glucose. The average concentration of cholesterol in the initial period, on
normal food, was 227 mg/dl. After two weeks on the restricted glucose diet, it
had dropped to 173. Two weeks later, the level was at 160. When the diet was
altered by replacing 25 percent of the glucose with sucrose (while all other
dietary constituents kept constant), the average cholesterol level rose from 160
to 178 within one week and to 208 within two weeks. The researchers carried the
study one step further. The sucrose was replaced with glucose again. With this
change, the cholesterol concentration dropped back to 175 within one week and
the decline continued. It finally leveled off at 150 mg/dl, which was 77 mg/dl
less than the initial value. This research finding links the consumption of
sucrose (table sugar) directly to increased cholesterol. The exact mechanism
is still under research.
In addition to glucose, fructose from fruits
also raises blood triglyceride level. In a clinical trial conducted
at the University of Minnesota, researchers followed 24 healthy adults who
received one of 2 diets assigned randomly for a period of 6 weeks and then
switched back to the other diet for 6 weeks. One diet provided 17% of energy as
fructose and the other diet was sweetened with glucose and was absent of
fructose. Both diets contain common foods and contained nearly identical amounts
of the macronutrients. The researchers found that in men, the fructose diet
raised plasma triglyceride levels by 32%, although there was no effect seen
with the women being studied.
Elevated triglyceride blood level of in itself is a strong and independent risk
factor for heart attack among middle-aged and elderly men. In fact, studies have
shown that blood triglyceride level was a stronger risk factor than total
cholesterol alone. It is not known why women appear to be immune to this
other than postulations that the high level of estrogen acts as a protective
factor. The exact mechanism is still under investigation.
High
Cholesterol - a Symptom and NOT a Disease
Elevated
cholesterol is a symptom and not a disease.
The real problem is
oxidative damage from excessive free radical damage caused by excessive
metabolism of oxygen and sugar. Humans lack the endogenous capacity to produce
vitamin C, a natural anti-oxidant. Instead, the body produces cholesterol as a
surrogate. If you understand this concept, it is easy to appreciate that high
cholesterol and a host of other age-
related
diseases such as arthrosclerosis is nothing more than a series of symptoms
reflective of the body's response to imbalanced oxygen and sugar metabolism.
The first and most important step
to
normalizing cholesterol level permanently is, in addition to exercise, proper
control of your oxygen load (through reduction of oxidative stress by taking
anti-oxidants) and
sugar load
(by avoiding foods that are high in sugar and concentrate on low glycemic index
food).
Unless you have high cholesterol due to familial factors,
lowering plasma LDL cholesterol can be achieved effectively by eliminating the
two key causative factors - excessive oxidation and sugar overload. This is best
done through a combination of nutritional supplementation, diet, and lifestyle
modifications.
Steps 1,2, and 3, when taken concurrently, will lower your cholesterol within 30 to 60 days. These three steps can be continued on an on-going basis.
Step 4
contains specific natural cholesterol
lowering agents that can be used for the short term reduction of cholesterol if
you desire a more potent action.
It can be added if steps 1,2, and 3 fail. This is not a mandatory step but an
option. Long term use of this step should be supervised by a knowledgeable
health professional.
1. Nutritional Supplements
A. Coenzyme Q10 (CoQ10) is a
foundation formula which enhances mitochondrial function.
CoQ10 supports
healthy HDL and prevents the excess oxidation of LDL. Statin drugs reduce the
level of CoQ10 in the body. Dosage: 30-90 mg daily.
B. L-carnitine, works
synergistically with CoQ10 to support healthy cholesterol and improves
transportation of nutrients from the extra-cellular space to the intra-cellular
space. Dosage: 250 -1,000 mg daily.
C. Garlic reduces triglycerides and
LDL cholesterol. In addition to using fresh garlic in your cooking (best to let
it sit for 20 minutes in open air before eating), you can also take a
therapeutic dose of garlic in supplement form. Dosage: varies, depending on
the product. Look for garlic supplements standardized to 12,000-ppm allicin
potential, and aim for at least 6,000 mcg of allicin per day. This is
equivalent to about 4 cloves a day. Garlic has a blood-thinning effect, and
should not be taken in large amounts if you are on blood thinners.
D. Digestive
Enzymes including lipase and amylase help breakdown food and aid
in digestion. Bowel transit time is also reduced, resulting in less stasis and
absorption of fat.
E.
Probiotics or "friendly bacteria" such as
L. Acidophilus help promote healthy cholesterol by converting it into a less
absorbable form and sending it down the gastro-intestinal tract for emptying. It
also increase enzyme production such as proteases that digest proteins and
lipases that digest fats. Dosage: 1- 2 capsules a day, between meals.
F. Milk Thistle (Silybum marianum) known as silymarin, is a group of flavonoid compounds. Silymarin prevents damage to the liver by acting as an antioxidant. It is much more effective than vitamin E and vitamin C. Liver is the major detoxification center of the body, and silymarin protects this organ against these toxins. Silymarin also works by preventing the depletion of glutathione. The higher the glutathione content, the greater the liver's capacity to detoxify harmful chemicals. In human studies, silymarin has been shown to exhibit positive effects in treating liver diseases of various kinds including cirrhosis, chronic hepatitis, fatty infiltration of the liver, and inflammation of the bile duct. Dosage: 70 to 200 mg one to three times a day.
G. Herb Tea. Enhanced intestinal motility is a key factor to optimum digestive health. Herbal ingredients and commonly used ingredients that enhance intestinal motility include: senna leaf, peppermint leaf, stevia leaf, buckthorn bark, damiana leaf, RED peel, chamomile flower, and uva ursi leaf. As a routine practice, it is always good to fortify your regular meals with digestive enzymes (to enhance the breakdown of food in the gastro intestinal tract). After your evening meal, you can begin drinking tea. Start slowly. You should begin by steeping the tea 2 minutes (in 1-2 cups of water) for the first 3-5 days. As your system adjusts, you may increase steeping to 5 minutes. Most individuals will experience increased bowel movements, or slight cramping, during the first few days. This is due to the initial cleansing of the body system and is normal.
H.
Pantethine and pantothenic acid, 400 to 900 mg each per day.
The use of pantethine to reduce total cholesterol, LDL cholesterol, and
triglyceride level, while raising the good HDL cholesterol at the same time,
is well documented. Bertolini et al
treated a series of 65 adults suffering from hypercholesterolemia alone or
associated with hypertriglyceridemia (types IIa and IIb of Fredrickson's
classification). Pantethine 1200 mg daily for adults was used for 3 years. In
adult population with type IIa hyperlipoproteinemia, the study showed a 25%
decrease in total cholesterol, a 39% decrease in LDL-cholesterol, a 34% decrease
in Apo-B, and a modest increase in HDL-cholesterol were observed. In adult
patients with type IIb hyperlipoproteinemia, total cholesterol was reduced by
19.8%, LDL-cholesterol by 37%, triglycerides by 31%, and Apo-B by 6%. In this
subgroup, a 23% increase of HDL-cholesterol and a 15% increase in apolipoprotein
A-I were also observed. In another
double-blind placebo-controlled study, 29 people with high cholesterol
and triglycerides were followed for 8 weeks. The dosage used was 300 mg 3 times
daily, for a total daily dose of 900 mg. In this study, subjects taking
pantethine experienced a 30% reduction in blood triglycerides, a 13.5% reduction
in LDL ("bad") cholesterol, and a 10% rise in HDL ("good") cholesterol.
Typically, a daily dose of 900 mg pantethine has
been shown to reduce triglyceride by 20-30%, total cholesterol by 10-20%, LDL
cholesterol by 10-20%, and a rise in HDL cholesterol by 10-20% in many studies.
I.
Polycosinol 5-10 mg a day. Policosanol is a
complex mixture of compounds usually extracted from sugar cane - but sometimes
from beeswax - that reduces blood cholesterol levels.
The purified extract from these two are slightly different. The active
ingredient is called octacosanol, and it is more abundant in the extract form
sugar cane. Studies since 1993 have
consistently shown policosanol effectiveness as a cholesterol-lowering agent. In
one of the earlier trials, 10 mg of policosanol administered once a day for 24
weeks caused total cholesterol levels to decrease by 22.1%.
2.
Modified Mediterranean Diet
The surest
way to reduce cholesterol is by reducing
sugar intake and not reducing dietary
cholesterol alone.
While we cannot live without sugar, excessive sugar leads to increased oxidative
stress, triglyceride formation and rising cortisol level. In addition to
causing an increased cholesterol production from the liver; these are all
pro-aging factors as well.
The anti-aging pyramid is a simple graphic format, based on the modified
Mediterranean Diet. It will reduce blood cholesterol levels by reducing
unnecessary sugar intake while supplying optimum nutrition. This food choice
program consists of 50-55% complex carbohydrates of
low glycemic index
type food (such as legumes, nuts, whole-wheat, and whole fruits), 20-25%
protein (preferably from plant sources), 25-30% fat, and 5% sweets, candies and
dessert. This is in sharp contrast to the typical American diet where 46%
comes from
simple carbohydrate such as white bread and pasta, and 43% of calories come
from fat (most saturated and trans-fat)

There are
three major layers to the Anti-Aging Food Pyramid. They are divided
into daily intake layers, 2-3 times a week, and once a week layers. Imagine a
pyramid with three groups of layers, each layer getting much narrower as it gets
closer to the top.
The broad base layers of the
pyramid start with 10 glasses of pure filtered water a day and complex
carbohydrates supplying up to 55% of the calories. These carbohydrates are low
glycemic index type - barley, cereal, legumes, and above ground green leafy
vegetables.
A limited amount of nuts, which is a fatty
food, is also included in this first base layer. Three servings of
vegetables should be taken daily. High glycemic index complex carbohydrates such
as wheat, rice, and corn should be restricted. A moderate amount is acceptable
if it is mixed with fat and protein.
Egg forms also part of the base layers. It is a good protein source. One
egg per day is acceptable (including those used in cooking and baking). Organic
eggs are the best.
Olive oil and fats from fish; nuts are part of this daily layer. 25-30%
of the calories in your comes from fats. The fats in the diet should come mainly
from olive oil, which is high in monounsaturated fats and also a good source of
antioxidant. Some come from the fish, poultry and meat consumed.
The second group of layers is a
much smaller layer contains protein food from fish and poultry. You should eat
from this group 2-3 times a week. Fish should be those that live in deep and
cold water, such as salmon and tuna. Poultry should preferably come from
free-range chicken.
The third group of layers, which is
very small, contains foods that one should eat 1 time a week. These include
sweets, red meat (lean).
Diet Tips for Lowering Cholesterol
a. Reduce
overall fat, especially trans-fat commonly found in fried foods and
margarine. Use oil or food that are high in Omega-3 fatty acid, such as olive,
rapeseed oil, flaxseed and flaxseed oil. Omega-3 fatty acid increase serum HDL
Cholesterol. Avoid polyunsaturated and saturated oil, as they increase the
cholesterol and triglycerides levels. Stay with mono-unsaturated fat such as
olive oil for all cooking needs.
b. Eliminate refined carbohydrates and sugar
from your diet and substitute complex carbohydrates that have lots of
fiber. Fruit should be the major source of sweetness in your diet. Fruits are
filled with pectin and fiber, which work wonders in lower serum cholesterol.
c. Foods that have been shown to lower LDL
cholesterol include oat bran, oatmeal, and dry beans out of a can.
Oat bran has been shown to reduce LDL cholesterol by up to 20%. Grapefruit -
segments and membranes, not the juice - drives down cholesterol. Also fresh
oranges, apples, garlic, onions, barley, ginger, and shitake mushrooms.
d. Eat lots
of raw onion - at least half a medium onion a day. This has been
shown to raise the good HDL cholesterol by up to 30%. Oat bran has also been
shown to increase HDL cholesterol by up to 20%.
If you want a step by step dietary approach,
Detox Diet Protocol will help you
to lower your cholesterol gradually.

3. Exercise
No diabetes program is complete without a
well-balanced
exercise program. While most people think
of exercise as a way to reduce body weight , exercise does much more, including
reducing insulin resistance and impotence.
A well-balanced exercise must include three components:
a. Flexibility training
b. Cardiovascular training.
c. Strength training.
Ideally, about
2000 calories
should be burned per week. Working out with 30 minutes of aerobics exercise at
moderate intensity 5 times a week plus 15-20 minutes of strength training 3
times a week will accomplish this goal.
4. Natural Lower Cholesterol Agents
A. Soluble
Fiber. Psyllium (Metamucil), a natural, water-soluble, gel-reducing
fiber, which is extracted from the husks of blond psyllium seeds (plantago ovata),
is a member of a class of soluble fibers referred to as mucilage.
Psyllium's total dietary content - 86 percent - is made up of 71 percent soluble
fiber and 15 percent insoluble fiber. This compares to 15 percent total fiber
and only five percent soluble fiber for oat bran. The soluble fiber in one
tablespoon of psyllium is equal to 14 tablespoons of oat bran, another soluble
fiber. For this reason, in contrast to oats, psyllium is added in relatively
small quantities to other cereal grains to make food products.
Numerous studies have found that patients with
mild to moderately elevated cholesterol levels can achieve a sustained reduction
of about 10% in cholesterol level by consuming psyllium twice a day
and adhering to the American Heart Association's (AHA) Diet.
Numerous landmark studies have been conducted to validate this. One is cited in
the December 1, 1996 issue of the publication OBGYN News. This study was led by
Dr. James Anderson, professor of medicine at the University of Kentucky College
of Medicine in Lexington. For six months, Dr. Anderson followed 248 patients who
were all instructed to follow the AHA diet. Some patients were given Psyllium
while others were given a placebo. The average cholesterol level for the study
population was 229 mg/dl, with an LDL cholesterol of 154 mg/dl. After six
months, members of the Psyllium plus diet group lowered their total
cholesterol by 8.6% and their LDL cholesterol by 11.1%, versus those in the
diet group who showed only a 4% reduction in both these levels. The researchers
further note that the Psyllium worked best for those people with the highest
cholesterol levels, with reductions of up to 25%.
Another well-designed controlled study, followed more than 100 adults with high
blood cholesterol (levels greater than 220 mg/dl). The study followed men and
women who ate a high-fat diet (40 percent or more of total calories) in
comparison to those who ate a low-fat diet (no more than 25 percent of total
calories). Researchers then compared the effects of adding 1 1/2 packets of
Psyllium (Metamucil) twice a day on blood cholesterol levels with the effects of
not taking the soluble fiber supplement.
After eight weeks, supplementation with Psyllium showed a small but significant
decrease in total cholesterol and LDL cholesterol levels, regardless of the type
of diet. Total cholesterol levels dropped a weighted average of 4.7 percent; LDL
cholesterol levels showed a 6.6 percent decrease.
Soluble fiber
causes loose bowel movements and may reduce gastro-intestinal motility on
chronic use.
Long term use should be directed under the supervision of a physician.
Dosage: 2 times a day.
B. Niacin is very effective normalizing cholesterol and Lp(a), the relative of LDL cholesterol and another independent and proven risk factor for heart disease. Since therapeutic levels of niacin is high and can cause an unpleasant flushing sensation and headache, gradually increase your dosage over several weeks or use the flush-free form of niacin, inositol hexaniacinate. Dosage: 100 mg twice daily, increasing to 500 mg daily. More may be needed under the supervision of a physician.
C.
Fish oil lowers blood triglyceride levels, may elevate HDL, and helps
support heart health. Most research studies are based on a high dosage of 3,000
mg. daily. At this dose, most people developed a harmless
fishy burp after consumption of fish oil
pills. If you take at least 12 ounces of fish a week, fish
oils are not needed. Dosage: 2,000- 3,000 mg
Laboratory Standard
From a laboratory test perspective of controlling cholesterol, the following
parameters should be considered optimum:
· Maintain a healthy total cholesterol level
at the upper limit of normal at around 200 mg/dl.
· High HDL level (more than 50 mg/dl) and a low LDL level (less than 130 mg/dl).
· Total cholesterol /HDL cholesterol ratio of less then 4.
· LDL/HDL cholesterol ratio of less then 2.5.
· Triglyceride level of under 150 mg/dl.
The best way to succeed is to limit the amount of simple refined
carbohydrates (sugar), processed polyunsaturated fats (corn oil), and trans fats
(donuts and fast foods), while maintaining a balanced diet of complex
carbohydrates of low glycemic index type (green leafy vegetables that are grown
above the ground), saturated fat from free-range animals (as in meat and
butter), and moderate amount of cholesterol (in meat and eggs)
Summary:
Elevated blood cholesterol is a symptom of rising oxidative stress and sugar
overload. Normalization of cholesterol level to the upper end of normal range
around 200 mg/dl should be the goal. Too low (below 150 mg/dl) a cholesterol
level is undesirable.
A three pronged concurrent approach is best,
consisting of specific nutritional supplementation, a modified Mediterranean
diet focused on low glycemic index foods, and a well-rounded anti-aging exercise
program. Additional natural agents such as niacin, fiber, and fish
oil in high dose can be added as an adjunct for short term use.
