vitamin-d-sourcesFew people are aware of the relationship between vitamin d and cholesterol, but it’s an important one and it shouldn’t be ignored. Although it’s called a vitamin, it’s actually a hormone and a deficiency of it can be life threatening!

It’s Actually a Hormone

Vitamin d refers to a number of is a fat soluble steroid molecules that are involved in the absorption of important minerals in your intestinal tract.

The two most important factors are:
vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol)

It’s also called the “sunshine vitamin” because it can be bio synthesized in your body when your skin is exposed to natural sunlight. This is especially important to people of African ancestry that live in temperate climates that have long winters.

Since their darker skin pigmentation filters out some of the suns rays, they are at increased risk of deficiency because of their skin filtering out natural sunlight (especially during long winters.)

For black people, supplements are a MUST! It appears that pretty much every disease that people of African descent suffer from disproportionately is linked with vitamin d deficiency. This is not widely known, but can still cause lots of health problems that could be avoided with wise use of supplementation.

The Cholesterol Connection

The human body is amazingly resourceful at bio synthesizing what it needs from what we put into our bodies. Thus when we have a deficiency of vitamin d the body will make it from cholesterol. This can cause your cholesterol levels to rise, because your body needs the extra cholesterol in order to synthesize this vitamin/hormone.

You have read in this blog that lowering cholesterol is not necessarily needed to prevent heart disease because it has been found not to be a direct causative factor. However if your cholesterol levels are elevated because of a lack of vitamin d then you need to take steps to supply your body with this nutrient by getting more sun exposure and taking supplements when you can’t get enough sun, such as in the winter.

Elevated cholesterol levels can indicate other problems in your body that you need to address. This is another reason why statin use can be problematic. It can mask the symptom (elevated cholesterol) that is being caused by another problem (like vitamin d deficiency).

Effects of Vitamin D Deficiency

  • increased risk of heart attack and stroke
  • depression
  • Parkinson’s Disease
  • increased risk of cancer
  • increased risk of infection
  • increased risk of multiple sclerosis

Some Food Sources of Vitamin D

  • Cod liver oil
  • Butter from grass fed cows
  • Beef or Calves liver
  • Egg yolks
  • Cheese
  • Water packed tuna
  • Oil packed sardines

Supplementing Vitamin D

Supplementary forms of this vitamin can be found in any health food store. My favorite is Jarrow Formulas D3. I opt for 5,000 units per day in the winter and half that dosage in the summer. It is difficult to overdose on this vitamin, as long as you are not using a synthetic version of it.

The ideal situation is that you get your levels tested by a doctor and do follow ups until the levels are where they are supposed to be. This is a fat soluble vitamin and so should be taken with a meal that contains healthy fats.

Vitamin k2 should be taken with vitamin d as those two nutrients work togegher to ewnsure that your body handles calcium properly. One of the top experts on vitamin K2 Dr. Rheaume Bleue suggests a ratio of 100-200 micrograms of K2 for every 1,000 IUs of vitamin d.   Again I would go with Jarrow Formulas MK-7, combined with their D3 product.

Sun Expose is Healthy

It’s been said before, but bears repeating…sun exposure is HEALTHY! Human beings evolved on the surface of the Earth. We NEED sun exposure in order for out bodies to function properly. Don’t avoid getting sunlight, because if you do, you are undermining your health in a critical way.

sunshine vitamin

sunshine helps your body synthesize vitamin D

Use common sense of course. Don’t overdo it, as too much of anything can be a problem, but remember that getting out in the sun and fresh air has benefits that go far beyond making you feel good and improving your mood.

How Much Sun Exposure?

This depends on how dark your skin is. Light skinned people should avoid prolonged exposure such as beyond 10-15 minutes in the sun. Darker skinned people of course can tolerate longer exposure, but you should be conservative with your time in the sun and gradually build a tolerance to sun exposure over time as you get more tanned.

Wearing a wide brim hat, proper sunglasses, and long sleeve clothing can help protect you as well. Remember also that you can get burned even on a hazy day because enough of the suns rays still get through and you may not be aware of how long you have been exposed.

Remember also that sunblock will prevent your body from making the vitamin d it needs from sun exposure, so If you are using sun screens on your skin you are defeating the purpose of getting sunlight.

cholesterol lowering foods

 

Cholesterol lowering foods have a lot more benefits than just promoting good cholesterol levels. Foods to lower cholesterol often have antioxidant and anti inflammatory benefits as well. These foods will help you lower cholesterol naturally, maintain a stable weight, fight disease, and add healthy years to your life!

Some of these foods you will be familiar with, and some may be knew to you, but the point is that you will have a wide variety of tasty foods to choose from, and they will result in better cholesterol numbers as well as reduced risk of heart disease, cancer, stroke, and diabetes.

Good cholesterol levels can be promoted in many ways, and your diet is a huge factor in what your cholesterol profile looks like. Focusing on cholesterol lowering foods is a great strategy because the reductions in cholesterol numbers will happen automatically just by eating certain foods.

Cholesterol lowering foods:

Foods to lower cholesterol work in several ways:

  • Foods with high fiber
    • Fruits like apples, pears, coconut, guava, grapefruit, berries, figs, apricots
    • Vegetables like greens, sprouts, squash, eggplant, green beans, and peppers
    • Whole oats, beans, legumes, lentils, peanuts
    • Nuts and seeds of all kinds
  • Foods that provide beneficial fats
    • Chicken, turkey
    • Free range grass fed meat, salmon and cold water fish
    • Avacados, olives
    • Nuts, nut butters, seeds, seed butters
  • Foods that provide antioxidant protection
    • Spices like curcumin (curry), cloves, cinnamon, oregano, nutmeg, chilli powder
    • Nuts such as peanuts, hazelnuts, pecans, walnuts, sunflower and pumpkin seeds
    • Onions, garlic, chilli peppers
    • Dark skinned vegetables, fruits like grapes and berries

These are ALL cholesterol lowering foods, and they work in different ways. They all contribute to better nutrition, digestion, and antioxidant status. These are healthy ways to achieve good cholesterol levels, rather than depending on toxic medication that often have severe side effects.

The foods listed above help lower blood sugar, which in turn lowers insulin (a very important aspect of heart health). some cholesterol lowering foods bind with bile acids containing cholesterol and help flush it from the body. They protect blood vessels from the effects of inflammation due to the antioxidants they contain.

This is the most important relationship between cholesterol and diet, not just how much cholesterol is contained in the foods you eat. Blood glucose levels affect your cholesterol profile, so any foods which lower blood sugar are beneficial in promoting good cholesterol levels.

Some of these cholesterol lowering foods also raise HDL! This is especially important because it is the HDL/LDL ratio that determines your risk of heart disease. So raising HDL is critical to protecting your cardiovascular system from the effects of inflammation.

When we talk about foods to lower cholesterol, these are ideally foods in their raw and natural state. Some foods do have to be cooked for safety, but when you can eat foods raw and unprocessed, so much the better.

Good cholesterol levels are generally defined as total cholesterol between 160mg/dl and 180mg/dl, with an HDL level of over 45mg/dl. Cholesterol CAN be TOO low, which is dangerous as well because it is associated with increased risk of serious illness, even heart disease!

The point of all this is that using cholesterol lowering foods to reduce cholesterol levels will allow you to do it naturally, so that your body will optimize it’s cholesterol production rather than using drugs to artificially lower it.

To sum up one again the 3 benefits of cholesterol lowering foods:

  • Foods that provide fiber to bind cholesterol and eliminate it from your body
  • Foods that provide beneficial fats to balance hormones and inflammatory pathways
  • Foods that provide antioxidants benefits to protect against free radicals and oxidative stress

The relationship between cholesterol and diet really depends on the above three factors. A diet that fails to do those things, is associated with high cholesterol levels, because your body is not functioning optimally.

Cholesterol lowering foods can do all of these things and more. They will promote longevity and good health, allowing you to avoid the devastating effects of cardiovascular disease, cancer, stroke, and diabetes. Yes foods to lower cholesterol can do all that, so enjoy them in good health.

HDL cholesterol level is the most important factor in your cholesterol profile. The cholesterol hdl ratio is used to determine your risk of a heart attack or stroke. Low hdl means greater risk, and I will explain the reasons why.

hdl cholesterol levelThe effect of cholesterol on your heart health has been distorted by bad information over the years. This is because pharmaceutical companies want to sell statin drugs, so they influenced doctors to set up guidelines that call for proscribing these drugs for lowering cholesterol levels.

The drugs do not lower cholesterol naturally, they do it by interfering with your body’s natural production of lipids, which is unhealthy and dangerous. What makes cholesterol a problem in your arteries is inflammation and free radicals which oxidize the cholesterol and turn it into hard plaques. Hdl cholesterol prevents this process, and protects you against heart disease.

How to raise increase good cholesterol

We know that HDL cholesterol functions as an antioxidant in the body. This means that it will help prevent LDL cholesterol from turning into dangerous plaques inside your arteries. This is why the cholesterol HDL ratio can predict your risk of heart disease. The higher the HDL cholesterol levels, the lower your risk.

So just how do we increase good cholesterol? We do it by diet, exercise, and using certain nutritional supplements that help boost HDL  levels.

Let’s start with diet! Below are some foods that can help increase good cholesterol:

  • Fatty fish such as salmon, tuna, mackerel, sardines
  • Raw nuts and seeds like walnuts, pecans, almonds, and flaxseeds
  • Whole eggs (yes that’s right…they must be WHOLE eggs)
  • Onions
  • Fresh raw low glycemic vegetables – especially dark leafy greens
  • Oat bran
  • Alcohol – 1 or 2 drinks per day maximum

These foods work in a natural way by giving your body the raw materials such as essential fatty acids it needs to raise  HDL!

Nutritional Supplements

Nutritional supplements can also help you increase good cholesterol

  • Fish oil
  • Pantothenic acid (vitamin B-5)
  • niacin – (vitamin B-3)
  • Gugulipid
  • Coenzyme Q-10
  • Carnitine
  • Vitamin-C
  • Vitamin-D
  • Magnesium
  • Polycosanol
  • Vitamin E-complex
  • Alpha Lipoic Acid
  • N-Acetyl-Cysteine
  • CLA – conjugated linoleic acid

All of these supplements help increase HDL levels, however niacin (B-3) and calcium pantothenate (B-5) are the most effective, so you should focus on them first, and add others if needed.

Exercise to raise your HDL cholesterol level

The best form of exercise is some kind of internal training. This might be circuit weight training, kettlebells, bodyweight exercises, ect. The main principle is the workouts should be brief, intense, and make your heart and lungs work hard.

Naturally, if you are older, or not on good health, you should get clearance from your doctor before engaging in strenuous exercise. You should also work into an exercise program gradually so that your body gets used to it. Never jump right into an intense exercise program. Take time to build up your exercise capacity so that you don’t overdo it.

The PACE program by Dr. Al Sears is an excellent exercise system for this!

Just what are good HDL cholesterol levels?

Remember that the cholesterol HDL ratio is very important. That determines your risk of heart attack. The table below reflects the Amercian Heart Association guidelines:

American Heart Association Guidelines

Desirable Borderline Risk
High Risk
HDL
60 or higher
40 to 59
40 or less (men)
HDL
60 or higher
50 to 59
50 or less (women)

Action steps to raise for your HDL cholesterol level:

  • Get your cholesterol HDL ratio tested so you know what they are to start
  • Work in 3 15 minute sessions of circuit or interval training per week
  • Avoid refined foods if possible – stick to raw fruits and vegetables
  • Get plenty of healthy fats in your daily diet
  • Supplement with niacin (B-3) and calcium pantothenate (B-5) to raise HDL

Your HDL cholesterol level is one of the best predictive markers for heart disease that we know of. HDL cholesterol protects you against heart disease, stroke, cancer, and Alzheimer’s disease. Make it a point to get your HDL cholesterol levels checked, get them into the healthy range and keep them there. Your heart will thank you!

The MTHFR gene is a hidden culprit in heart disease and explains much in the reasons why cholesterol numbers don’t tell you what your real risk for heart disease is. Understanding how this gene defect affects your good cholesterol levels and how to treat it is essential to protecting yourself from heart attacks.

MTHFR geneWhat is the MTHFR Gene?

This gene is responsible for operating what are called “methylation pathways” that involve your body’s ability to convert certain substances into their reduced or active form. If this gene is defective in your body, these vitally important methylation processes cannot be completed properly, and certain substances (vitamins and amino acids) can’t be absorbed by your body and you develop deficiencies.

Some of these substances are:

  • vitamin b-12
  • folic acid
  • cystiene

In the case of b-12 and folic acid, these substances are converted to their active forms of methylfolate and methylcobalamin. These active forms are what your body can actually use, and so if you can’t convert them properly, you end up with a deficiency.

Cystiene is converted to the toxic amino acid homocysteine and then to methionine. If your methylation pathways are not working properly due to the MTHFR gene defect, then you end up with an accumulation of homocystiene which is highly inflammatory and causes damage to your arteries.

How is Your Good Cholesterol Level Affected?

HDL-C also called the “good cholesterol,” can be effectively lowered by a certain type of MTHFR gene defect called: C677T polymorphism.  Since HDL is protective and lowers your risk of heart disease, this gene defect can raise your risk by lowering your good cholesterol level.

There are several variants of this gene defect, and they affect cardiovascular risk in different ways, but it’s important to be aware of their impact so that you can protect yourself. Remember that 50% of heart attacks occur in people who have what’s considered normal cholesterol levels.

The affect of the MTHFR gene is seen by many researchers as the missing piece of the puzzle in trying to determine why this is so. With this information you can go about protecting yourself by applying this new knowledge and lowering your risk not only for heart disease, but also for other chronic diseases that are caused by inflammation.

What Other Problems Can This Lead To?

A defect in the MTHFR gene can also result in increase risk for the following diseases:

  • Cancer
  • Stroke
  • Fibromyalgia
  • Polyneuropathy

How Do You Know if You Have it?

This is a very important question, because once you detect this, then you can guard against it’s effects. The most simple test you can do is to eat asparagus and note if your urine has a strong odor in the hours following your meal.

If this odor is present when you urinate, (you can’t miss it), then you can be sure that you do in fact have a defect (called a polymorphism) in the way your MTHFR gene operates. There are also lab tests that your doctor can do to detect this problem.
It may be necessary to have formal lab tests done so that this problem can be medically verified. It’s also important because your doctor has to order it for your insurance to cover it. The best and most responsible advice I can give you is to go through your doctor and get tested for this.

Fortunately there are ways to treat this problem, that will work and help to protect your health, but of course the first step is to determine whether you have it or not, and your doctor can order the tests to confirm it.

What Can I Do?

A defect in the MTHFR gene results in failure to operate certain methylation pathways and convert amino acids properly. However, forms of critical b-vitamins, vitamin B-12, and Folic acid, in their “active” forms, which means they do not have to be converted or methylated, CAN be absorbed by your body and help ensure these critical chemical reactions happen as they are supposed to.

Thus instead of taking folic acid, you would take “methyl-folate.” Instead of taking vitamin B-12 (cyanocobalamin) you would take “methylcobalamin.”

There are other substances that can help. They are called “methyl donors” because they donate or provide what’s called a “methyl group” to help the chemical reaction complete properly. There are foods that contain “methyl donors,” such as garlic, onions, avocadoes, ect.

There are also nutritional supplements such as trimethylglycine, and SAMe, as well as special formulations that contain combinations of these methyl donors to help provide what your body needs to do these conversions properly.

None of these substances are drugs, nor are they prohibitively expensive. However, most mainstream doctors do not know about them, nor about defects in the MTHFR gene, and so you may have to search for a physician that is up on the latest genetic research, that can help you safely manage this problem.

The website I recommend is:

http://mthfr.net/

which is a website run by Dr. Benjamin Lynch. There is a wealth of information on this website regarding methylation issues and the MTHFR gene. If you have this gene defect, I would highly recommend that you visit this website and educate yourself.

You can also click on this video:

to learn more about this topic, and start arming yourself with powerful information that will allow you to protect yourself against heart disease, cancer, strokes, Alzheimers, and other effects of methylation problems.

My reasons for delving into this topic is that it fills in the missing information that cholesterol numbers leave out. The effects of this gene defect on your good cholesterol level is probably one of the main reasons for the increased risk of heart disease.

Defects in the MTHFR gene are one of the most significant drivers of chronic disease, and by knowing if you carry this defect, you can takes very strong steps to protect your health and to live better and longer.

The PLAC test is a cutting edge medical screening test that identifies arterial The PLAC Testplaque that is in danger of rupturing. This test, used in conjunction with other cholesterol screening tests can pinpoint your risk of a sudden heart attack with a much greater degree of certainty.

The test actually measures levels of an enzyme in your blood known as lipoprotein phospholipase A2. This enzyme is responsible for a process that can cause damage to your endothelial layer and set the stage for atherosclerotic plaques which can rupture and trigger a heart attack.

When your levels of Lp-PLA2 are elevated, it indicates that you have plaque that can rupture and create a blood clot that results in a heart attack or stroke.

The most current information we have tells us that using cholesterol levels to determine your risk of heart attack is not very accurate. However medical science has identified a process where LDLs (low density lipoproteins) and Lp-PLA2 particles undergo oxidation by free radicals.

These oxidized particles then attack the blood vessel wall causing damage and making the plaque deposits hard and brittle. This oxidized brittle plaque can then break off and cause life threatening problems such as a heart attack or stroke.

Lp-PLA2 is actually created in atherosclerotic plaques and thus can serve as a marker for inflammation in the artery wall. People who have heart disease show high levels of this marker (Lp-PLA2) which not only indicates they have plaque buildup, but also that the plaque is oxidized and can cause severe cardiovascular events.

Autopsies on patients who died suddenly of heart attacks showed ruptured plaques and high levels of Lp-PLA2 in their arteries.

This has also been see in patients who undergo surgery for carotid artery atherosclerosis. They show the same high levels of Lp-PLA2 that indicates a danger of rupturing plaque.

Those people who showed atherosclerosis of the carotid artery but did not show symptoms had much lower levels of Lp_PLA2. It’s clear from this evidence that this is a very significant and useful marker for predicting sudden cardiovascular events.

Studies done at the May Clinic also found that Lp-PLA2 was a specific indicator of dangerous plaques even in the absence of other risk factors. This indicates that it is inflammation and not merely cholesterol levels that create the risk of sudden heart attacks and stokes, so it is inflammation that we should address in our efforts to prevent heart disease.

Advantages of the PLAC test:

  • The test more accurately predicts the risk of sudden heart attack or stroke than other lipid screening tests.
  • The test directly measure lipoprotein phospholipase levels, a very accurate inflammation marker.
  • The PLAC test is the only medical screening approved by the FDA that indicates both heart attack and stroke risk in patients.
  • The test is relatively inexpensive and convenient.
  • The test can also be used to monitor a patients response to treatment and lifestyle changes.
  • The test is covered by Medicare and private insurance companies.
  • The test does not have to be taken in a fasting state.
  • The test can be used in patients that are currently using Pravachol, Benadryl, and Tylenol

Who should get the PLAC test and when?

Experts recommend a formula for determining who should get the test based on other risk factors and their estimate risk of sudden heart attack within a ten year period. This makes no sense to me at all. We have a test that can specifically identify people who are a high risk for a heart attack or stroke, before this actually happens and give them a chance to lower their risk.

I believe the PLAC test should be used as a standard cardiovascular screen test, because it targets the process that is actually dangerous, rather than cholesterol levels which don’t really give an accurate measure of your risk. Once the test has been done, all that’s left is to determine how to go about lowering the risk, by reducing the inflammation in your arteries.

As to who should have it done, it makes sense to me that anyone approaching middle age would be a candidate for it. Autopsies of US soldiers killed during the Korean War showed atherosclerotic plaques in the arteries of young men in their 20’s. Based on this it seems reasonable that the test could even be done on people in their early 20’s as a way of identifying people who may be at risk and giving them plenty of time to make the lifestyle changes needed to protect themselves.

People with metabolic syndrome which consists of the following:

  • obesity
  • abnormal blood lipid profile
  • elevated blood sugar
  • high blood pressure

are prime candidates for the PLAC test, as it is known that metabolic syndrome involves inflammation and thus raises the risk of heart disease.

The test can be done at followup intervals to verify the success of lifestyle changes and other interventions in terms of lowering the patient’s risk. While I claim no medical expertise, common sense suggests that this test be done early and the person then adapt their lifestyle, nutritional and exercise habits to mitigate this risk. That approach makes the most sense.

How to interpret the test results:

Even though the Lp-PLA2 test is much different than cholesterol screening tests, the levels are somewhat similar:

The 3 risk levels are:

Low:   under 200 ng/mL

Borderline:  200 to 235 ng/mL

High:  over 235 ng/mL.

Lp-PLA2 levels over 200 to 220 ng/mL indicate a very high risk of endothelial damage which in turn presents a very high risk of atherosclerosis.

Medical Interventions:

The PLAC test can be used to identify the magnitude of risk and also to determine how well the treatments used to combat it are working. This is why followup tests are important.

Statin drugs are said to provide a 20-30% reduction in Lp-PLA2 levels. The risk to benefit ration of statins is something you will have to discuss with your doctor.

Niacin used in combination with statins is reported to provide an additional 5 to 20% further reduction of the Lp-PLA2 enzyme.

Angiotensin-converting enzyme (ACE) inhibitors are also reported to lower Lp-PLA2 levels, and medical scientists have speculated that the effectiveness of all cardiovascular drugs may actually depend on their ability to successfully lower Lp-PLA2 levels

Niacin and omega 3 fatty acids (fish oil) also show an ability to reduce levels of Lp-PLA2.

Tumeric spice (also called circumin) has been found to reduce a form of phospholipase in animals, and thus may be of value to humans in reducing Lp-PLA2 levels, but the study results are not in on this yet. My guess is however that turmeric is most probably of value in human as well.

Conclusion:

Since heart disease is the nation’s number one killer, preventing it is vitally important to a long and health life. Medical screening tests such as blood pressure and cholesterol are not enough to accurately predict who is a risk for a heart attack or stroke.

The PLAC test is relatively inexpensive, non invasive, and very accurate in predicting who is at high risk for a sudden cardiac event like a heart attack or stroke. It really represents a cutting edge approach to identifying people at high risk and helping them make the changes that can save their lives.

Carotid ultrasound  is a non-surgical and painless test that is used to determine the amount of blockage of your carotid arteries. This is done by using ultrasound to create an image of the inside of the arteries.

carotid ultrasound
This allows the physician to assess the blood flow though your arteries and detect blockages caused by plaque buildup inside the carotid arteries that could put you at risk for a stroke.

This narrowing of the arteries is called “stenosis,” and is considered to be a big risk factor for strokes. There are two such arteries, one on either side of the neck. These arteries carry blood to the brain, and if this blood flow is interrupted, it can result in a stroke.

An ultrasound imaging of your carotid arteries is one of a number of tests that can be done to determine the extent of blockage or stenosis. There are several types of ultrasounds used. If you need this screening procedure, you should discuss with your doctor which version is appropriate for you.

Types of Carotid Ultrasound

There are two main types of tests that are used to image the carotid arteries.

  • Doppler ultrasound: This test actually creates images of the blow flow though the arteries.
  • Standard ultrasound: This test creates an image of the actual structure of the inside of the arteries.

Why are these tests performed?

The doctor may order a carotid ultrasound because he or she suspects there may be blockages or other types of damage to the artery wall that can prevent blood from getting to the brain, causing what is called an ischemic stroke, which is life threatening.

The problem may be a blood clot, or something called an artery dissection which is a damaging split in the artery wall. This condition can impede blood flow, or seriously weaken the artery wall, possibly leading to a stroke.

Another problem can be a narrowing of the artery because of plaque buildup involving bad cholesterol levels, which is called stenosis. This can be indicated by something called a bruit, which is a sound the doctor hears when using a stethoscope to externally examine your carotid arteries.

These abnormal sounds can indicate stenosis, so the doctor uses the carotid ultrasound to further determine just what is happening inside the arteries. There are other things that might cause the doctor to suspect artery disease such as:

  • High blood pressure
  • Advanced age
  • Diabetes
  • Bad cholesterol levels
  • Birth defects that affect the carotid arteries
  • Strokes
  • TIA’s (transient ischemic attacks)
  • Tumors (very rare)

Who would perform the test?

This test is performed by a medical professional called a radiological technician. This is a person trained in both the procedure and preparation for medical imaging scans. The test will sometimes be performed by a doctor called a radiologist. These physicians are experts on performing and analyzing the results of medical imaging scans.

The radiologist will analyze the carotid ultrasound results and give your doctor a diagnosis based on the imaging scans of your carotid arteries.

How carotid ultrasound works

The equipment operated by the radiological technician generates high frequency sound waves that are projected into your body by a hand-held instrument called a transducer. When these sound waves strike your tissue and are reflected back to the transducer, it creates an image of the shape and structure of the tissues being scanned.

The biggest advantage of carotid ultrasound is that it is non-invasive, meaning that no piercing or cutting of the skin surface is necessary, and that the scanning technology uses sound waves which are much safer than other imaging technologies that use ionizing radiation which can damage tissue.

How is this test performed?

This test is usually performed in a hospital or sometimes in an outpatient clinic. It takes about an hour and usually involves the following steps:

1) You dress in a standard patient exam gown sometimes called a Johnny. You can also wear your own clothing as long as the neck area is open and there is no jewelery around your neck.

2) You lie on the exam table, on your back, and the radiological technician applies a gel to your neck that helps the equipment make proper contact with your skin.

3) The tech will then place something called an ultrasound transducer on your skin. This is a hand held instrument that sends the sound waves into your body. As the tech moves it around on your neck it produces an image of your carotid artery and surrounding area. This process is completely painless.

4) When the ultrasound is finished the gel gets wiped off. You will have to wait a few minutes until the tech or radiologist makes sure that the scan is complete, and then they will send you home.

5) Your doctor will then contact you with the results of your scan and the diagnosis he has been given by the radiologist.

The carotid ultrasound is a very valuable test because it allows your doctor to see exactly how much plaque buildup there is in your carotid arteries and then create a treatment protocol based on this precise information. This test could warn you in time to prevent a stroke or other serious medical problem, which makes it one of the most effective tests for prevention there is.

Soluble fiber for cholesterol is another safe and healthy way to lower cholesterol naturally, which lowers your risk of heart disease. Using fiber to lower cholesterol is a safer alternative to toxic drugs, besides which foods high in fiber have many other health benefits.

soluble fiber for cholesterFoods high in fiber have an important function in your body, and help to lower your risk of several chronic health conditions. Such fiber rich foods should be included in your diet on a daily basis.

Soluble means that your body can break them down, as opposed to insoluble which means that they pass through your digestive system without being broken down.

What foods contain soluble fiber for cholesterol?

Here is a short list of foods high in fiber.

  •     Psyllium husks
  •     Peas, beans, lentils
  •     Oats, oat bran, wheat bran,
  •     Broccoli, carrots, squash, potatoes, Zucchini
  •     Apples, oranges, tangerines, plums, strawberries, blackberries, apricots

There are more comprehensive lists of foods high in fiber online, but the above list gives you an idea of common foods that you can include in your diet to lower cholesterol naturally.

How do foods high in fiber work?

Research studies have established a positive correlation between dietary fiber and lowered cholesterol levels. There are 3 mechanisms that possibly explain this lowering effect:

  • Preventing cholesterol to be re-absorbed from bile sales and causing more of it to be excreted by elimination (feces)
  • Lowered glycemic response and reduced stimulation of cholesterol synthesis in the liver
  • Fermentation effects of soluble fiber affect bile salts and cut down on re-absorption in a way that is not well understood by science

Excess cholesterol that is not used by the body to synthesize hormones or other important functions is combined with bile acids in your large intestine, is recycled through your liver, and ends up back in your bloodstream.

Foods high in fiber can bind with the cholesterol and help transport it out of your body when you move your bowels. This is part of the way that foods high in fiber can lower cholesterol naturally, rather than using statin drugs that have dangerous side effects.

Remember as well that these sources of fiber only work optimally when you are well hydrated. Water is essential to getting the maximum benefits from fiber on your diet, so make a point to consume plenty of clean pure water throughout the day.

Using fiber to lower cholesterol does work and has been shown to be effective in well conducted studies. The role of soluble fiber for cholesterol has been known for years, but the public has only recently been made aware of it’s benefits.

You could say that using soluble fiber for cholesterol is the most natural way to optimize your cholesterol levels and fiber has other health benefits as well as it’s effect on blood lipids. Better function of your gastrointestinal system (gut) improves health across the board, and fiber has been shown to be beneficial to improving levels of pro-biotic bacteria in the colon.

Daily Recommended Amounts

The USDA recommends 14 grams of fiber for every 1,000 calories consumed for healthy adults. This works out to about 25-30 grams of fiber per day. The average for adults in the United States is approximately 15 grams.

Increased intake of fiber to lower cholesterol has also been associated with a lower risk of cancer, stroke, Alzheimer’s disease, and diabetes, as well as heart disease. Foods high in fiber thus have many benefits beyond helping to optimize cholesterol levels.
