NY Times Jane Brody misses the mark



NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper:

"CT Scans of the Heart Come With Trade-Offs


In her report, she says:

Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.

I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.



She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent.

This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like:

--the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.

--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors.

--There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham.


Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness.

If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.

"There must be a mistake"

Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!)

You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to

http://www.cureality.com/library/fl_07-001nealt51.asp


Neal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results.

After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop."

The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment.

Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal.

I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal.

Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help."

Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them.

Should this happen to you, don't be surprised. Just bite your tongue, because you know better.

Jimmy Moore Interview: Is saturated fat the villain we thought?

Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore.

On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment."

Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer.

But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts.




TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program.

I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?





JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.

While we do agree on probably 99% of the basic tenets of what I describe as
"livin' la vida low-carb," the issue of saturated fat to me is one where we
indeed do not. It's not a deal breaker regarding my support for what you do
just as I'm sure you would say the same regarding your backing of what I do. If
we all agreed on everything, then what a boring world this would be!

My thinking on saturated fat has evolved since I started eating this way nearly
four years ago. Like most people, I was terrified to eat ANY fat at all because
of the abject fear that people like Dr. Dean Ornish and other so-called health
"experts" instilled in me about how dangerously unhealthy it is to consume it.
This fat phobia is arguably the single biggest contributor to the ongoing
obesity crisis our world faces today.

With that said, you and I both know fat consumption is a part of a healthy
lifestyle. There are just too many benefits to the body that come from the
consumption of fats and even saturated fats such as coconut oil, butter, lard,
nuts, seeds, and animal fat when it is combined with a restricted carbohydrate
intake.

An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.

Here are the actual numbers from the study:

- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%
- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%
- Eating 3X the saturated fat cut the amount in the blood in half

In an interview I conducted at my blog with Dr. Volek last year (here's the
link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html),
he said the conventional wisdom regarding fat, especially saturate fat, is dead
wrong while the significance of carbs is all but ignored by those who claim to
understand the metabolic response mechanism.

Here's what Dr. Volek said in my interview:

"Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."

Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.

Here's what she said:

"Eating fat (whatever kind) does not make you fat. It does not increase blood
stream saturated fat. Eating carbs does make you fat. Eating carbs does put
saturated fat in your blood stream."

To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.

And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.



TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc.

Have you encountered any phenomena of low-fiber on your approach?

JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html).

Fiber consumption is another one of those issues that not everyone who advocates
a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet.
Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).

As for consuming the highly-touted "healthy whole grain" cereals that you
mentioned, what a travesty that would be for people trying to manage their
weight and health. While the cereal manufacturers have had a heyday in their
marketing efforts promoting their whole grain content, it's all just a big fat
ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!

Many of these "healthy" cereals contain as many carbohydrates in a single bowl
without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.



TYP: 180 lbs of weight loss in your first year is absolutely astounding.

I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently?
How are your food choices today different from that first year?

JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!

It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).

There's a balance that people need to find for themselves and it's different for
all of us. I am one of the unlucky people who has to keep his carbohydrate
intake below 50g daily or I gain. It's just a fact of life that I've come to
grips with and realize is a necessity in order to manage my weight for the rest
of my life. But I wouldn't have it any other way!

Exercise was indeed a part of my low-carb weight loss success in 2004 as I
forced myself to do cardio every single day as a commitment to this journey. In
hindsight, that was probably not the best thing for me to do since the body has
a rather peculiar way of telling you it needs to wiggle and move spontaneously
on its own rather than forcing the issue. But I consider the exercise I did to
be such an integral part of my success that I dedicated an entire chapter of my
book to the subject.

Today, my daily cardio routine is out the window and I choose instead to engage
in activities outside the gym that let me burn calories and have some fun in the
process. I regularly play volleyball, basketball, and referee flag football at
my church which all give me quite a workout. I'm very physically active and fit
on my 6'3" body and just enjoy burning off all this excess energy that I have
been given since losing nearly have my weight! I do want to get into a little
more organized resistance training routine soon to try to shape and tone some
areas of my body that still show signs of that 410-pound man I used to be
(although the loose, hanging skin in my abdomen and inner thighs isn't going to
get any better with exercise since the elasticity has been ruined from being
stretched out so far). Here is a link to some posts and pictures I have written
about this subject:
http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.html

As for my food choices today compared to my weight loss year in 2004, they
haven't really changed a whole lot. This was a lifestyle change in every sense
of the phrase and I've learned to implement this way of eating into a permanent
and healthy diet that I can and will gladly live with forever and ever amen. I
probably eat more berries, melons, and nuts today than I did then, but otherwise
it's the identical diet.



TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years.

Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins?

JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone.

Nope, I sure don't!

Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.

Anyone interested in doing the low-carb lifestyle and needs help finding which
plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html).
It's the perfect overview of low-carb living with a comparison and recap of the
major plans.

THANK YOU again for allowing me to share my story with you and your readers, Dr.
Davis!

TYP: And thanks to you, Jimmy!

Mammogram of the heart

Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.

First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).


















Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)



Both are also meant to be repeated periodically when normal as a surveillance process.

Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.

Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).

Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.

Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography.

CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries.

One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency.


Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.

Dr. Susie Rockway on conjugated linoleic acid (CLA)

I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements.

A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives.

So I asked Dr. Rockway if she’d answer a few questions for us.






TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic?

Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!)

I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction!

Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health.

I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently.

So, how can you not be excited about this very bioactive molecule?




TYP: What are your specific areas of interest in nutrition and health?

Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health.

As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should.

Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there.

Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at.

Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research.



TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts?

Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.

When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood.

So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure.



TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years?

Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short!

We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!

One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education.

Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition.

See, it all comes back to CLA!


TYP: Thanks, Susie!

Which is better?

If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:




Lipitor or a combination of fish oil, vitamin D, and elimination of wheat?


Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.

Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%.



A combination of fish oil, vitamin D, and elimination of wheat:

Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events.



On this combination, however, you also:

--Lose weight, often substantially.

--Improve bone health, esp. osteoporosis and arthritis.

--Reduce cancer risk from the vit D supplementation.

--Reduce risk of stroke.

--Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.

--Reduce winter blues.

--Experience more energy.

--Obtain increased clarity of thought (from elimination of wheat).

--Reduce blood pressure.


Oh, and there's no muscle aches.

Heart health for stupid people

I'm kidding.

What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public.

A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:

Eat healthy--by eating a "balanced" diet low in saturated fat

Don't smoke

Exercise

Don't ignore chest pain symptoms or breathlessness

Know your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."


Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?

How about some real heart healthy advice:

Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.

If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).

Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.

Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.

Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.


That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice.

Money, money, money, money

I've been asked the question numerous times:

Why aren't heart scans more popular?

First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is:

Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice?

That's easy: There's no money in it.


Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans.

This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer.

Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan.

With heart scans, there simply is no big payoff.

We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area.

The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.

I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money.

I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007.

The many faces of LDL

Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.

As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:

LDL cholesterol: 96 mg/dl
This value puts Ginnie's LDL in the most favorable 25% in the country.


LDL particle number: 2140 nmol/l
This value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).

In addition, over 90% of Ginnie's LDL particles fell into the small class.

Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:

Apoprotein B somewhere in the 120 to 140 mg/dl range

Direct LDL 100-130 mg/dl range.


In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.

It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.

Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.

In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.

I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.

We will be working on some solutions in the coming months.

What does "Success" mean in the Track Your Plaque program?

Say you begin with a CT heart scan score of 400.

You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns.

One year later, you get another heart scan. What score would constitute "success"?

With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed?

For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack.

You can read about how we view the various forms of success in the program by reading our latest Track Your Plaque Special Report, Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.

Genetic vs. lifestyle small LDL

Genetic vs. lifestyle small LDL

Let me explain what I mean by "genetic small LDL." I think it helps to illustrate with two common examples.

Ollie is 50 years old, 5 ft 10 inches tall, and weighs 253 lbs. BMI = 36.4 (obese). Starting lipoproteins (NMR):

LDL particle number 2310 nmol/L
Small LDL: 1893 nmol/L
(1893/2310 = 81.9% of total, a severe small LDL pattern)


Stan is 50 years old, also, 5 ft 10 inches tall, and weighs 148 lbs. BMI = 21.3. Starting lipoproteins:

LDL particle number 1424 nmol/L
Small LDL 1288 nmol/L
(1288/1424 = 90.4% of total, also severe)


Both Ollie and Stan go on the New Track Your Plaque diet and eliminate wheat, cornstarch, and sugars, while increasing oils, meats and fish, unlimited raw nuts, and vegetables. They add fish oil and vitamin D and achieve perfect levels of both. Six months later, Ollie has lost 55 lbs, Stan has lost 4 lbs. A second round of lipoproteins:

Ollie:

LDL particle number 1810 nmol/L
Small LDL: 193 nmol/L
(193/1810 = 10.6% of total)


Stan:

LDL particle number 1113 nmol/L
Small LDL 729 nmool/L
(729/1113 = 65.4% of total)


Ollie has reduced, nearly eliminated, small LDL through elimination of wheat, cornstarch, and sugars, along with weight loss, fish oil, and vitamin D.

Stan, beginning at a much more favorable weight, reduced both total and small LDL with the same efforts, but retains a substantial proportion (65.4%) of small LDL.

Stan's pattern is what I call "genetic small LDL." Of course, this is a presumptive designation, since we've not identified the specific gene(s) that allow this (e.g., gene for variants of cholesteryl ester transfer protein, hepatic lipase, lipoprotein lipase, and others). But it is such a sharp distinction that I am convinced that people like Stan have this persistent pattern as a genetically-determined trait.

    Sounds like Stan is screwed. Of course, there may be other factors mitigating his lipid pattern because he avoids the neolithic agents. Stan would be more susceptible to heart disease than ollie on the SAD, but not when they both have good diets?

    So Ollie and Stan BOTH show substantial improvement on their LC diets.

    The difference between them may well be due to genetics, but where is the evidence that Stan needs to avoid saturated fat?

    Did you advise Stan to increase sat fat and then watch his sdLDL get worse?

    If they accomplished this with "oils" at the expense of saturated fats (oils are liquid due to the paucity of saturated fats in them), then it looks like they both have a saturated fat deficiency, and one could speculate that Stan is even more deficient than Ollie.

    Swap out the nasty oils for more butter and beef fat and coconut fat and maybe Ollie will have sdLDL of 0 (like I do on 35% of calories from sat fat) and Stan will improve even further.

    Hi Dr Davis,

    You describe a fascinating scenario.

    Ollie has clearly lost weight. He has lost 55 lb in 6 months. That is nearly 10 pounds of "lard-equivalents" each month. This has not evaporated. It is exactly what he has been running his metabolism on. Whatever nuts and vegetables he has eaten can have been nothing in comparison to the 4 times half pound blocks of lard he has "eaten" from his own adipose tissue, every week. Result: Metabolism runs on lard and sdLDL plummet.

    Stan has lost minimal weight so has run his metabolism on  his food alone. If this is low in lard he may well be running his metabolism on vegetable derived carbohydrate and nut derived omega 6 PUFA. It's possible he has NOT been eating 2lb of lard a week in his diet, because obviously this might raise his LDL. So he has NOT used lard to fuel his metabolism, he has used nuts and vegetables when Ollie has used lard from his adipose stores.

    Before I would blame genetics I would get rid of the nuts and unlimited vegetables from Stan's diet and replace them with exactly the same the adipose tissue derived fuel that Ollie was using. If Stan cannot spare it from his butt (he certainly cannot at BMI 21), it's going to have to go on his plate. Two pounds of lard a week.

    Then compare sdLDL values, when you have similar metabolic situations... Until then Stan just has nut and vegetable poisoning showing as sdLDL.

    There do not have to be any genetics involved. There might be, but let's keep it simple for the time being... Ollie is on lard while he is losing weight. Mimic that.

    I think it's somewhat telling that you advise your patients to eat "oils."  What kind of "oils" are they eating?  Why are your patients eating unlimited nuts?

    Until you get off the Omega-6-loaded "heatlhy" polyunstaturated fats bandwagon, it's hard to take your clinical observations on "fats" very seriously.

    Dr. Davis,

    Help me understand the part about not eliminating meats or fats.  First, here is my blood work 15 days apart.

    Total cholesterol 295 - 15 days later 156
    LDL 200 - 15 days later 102
    HDL   46 - 15 days later  32  (have added 1500mg of niacin since then)
    Triglycerides   242 - 15 days later 109
    VLDL  49 - 15 days later 22
    Vitamin D was 28 – 15 days later it’s 56 (using 10,000 of Carlson’s D3)

    FYI my heart scan was 899 (54 year old male)

    I started on all the main nutrients you recommend here plus a few.  I dropped dairy like a hot potato including 6 or more ounces of cheese a day.  During those 15 days I ate only plant based foods (have since added some salmon and egg whites)

    The only oil I use now (sparingly) is olive.  I have a couple of gallons of coconut oil I assumed would have to be tossed sooner or later.

    Guess you could say I became fat paranoid and downright phobic about any saturated fat.

    Am I understanding I could add back Grass-fed beef (omega-3) pastured chicken and Omega-3 whole eggs?  Coconut oil?   If so, is there some safe percentage of a person’s diet to include those proteins/fats?

    By the way, my doctor wouldn’t let me out of his office without a copy of your book.  He’s one in a million as are you!

  • Dr. William Davis

    2/19/2010 3:08:19 AM |

    I have indeed had many people with presumed "genetic small LDL" load their diets with oils and fats with only minor improvement. Loaded with saturated fat, however, and there seems to be deterioration.

    I know this flies in the face of the "saturated fat is great" dogma, but I don't make this stuff up. Just as I don't make up the deterioration of postprandial triglycerides and chylomicron remnant effect when saturated fats are loaded heavily in the diet.

    The persistence of small LDL is also long-term, i.e., it persists for years despite continuing efforts.

    But Dr. Davis, those all chock full of PUFAs

    Linseed oil (flax oil) is 71% LA and ALA

    Rapeseed oil (Canola oil) is 33%  LA and ALA

    Almond oil is about 25% PUFA

    Even olive oil can be up to 20% PUFA

    And all of these are mostly Linoleic acid.

    All best left as industrial lubricants and paint additives rather than eaten.

    2/19/2010 4:10:32 AM |

    So, you have a fat guy, who has been living on (his own) saturated animal fats, and he has improved a lot.

    Then you have a skinny guy, who has been living on "healthy vegetable fats" with surprisingly much LA in them, and he has not improved that much.

    So, it seems to tell that without saturated fats LDL improvement is much harder in LC, to say it kindly.

    And it sounds as if butter and saturated animal fats would be advantageous for the latter guy, too. Have they ever tried this, under your coucelling?

    Dr. Davis,

    While body composition certainly isn't a prerequisite for being part of a classic comedy team, I couldn't help but notice that Stan had the makings of a skinny-fat bean pole checking in at 5' 10" and only 148 pounds. Those stats make him sound like a diehard distance runner or a chain smoker.

    While it was clearly just for illustrative purposes, I couldn't help but think that, if "Stan" exercises at all, he must not be exerting himself very much. I'm not advocating that every older gentleman suddenly attempt to impersonate Mr. Olympia, but I have to wonder seeing such a lightweight. That's not to say that I think sufficiently intense exercise would remove the problem that is genetically-based small LDL, but it is enough to make me raise an eyebrow when I see that type of weight for a male listed as 5'10".

    Olive oil is monounsaturated but flaxseed oil, canola oil, avocado oil, almond oil, and oils from raw nuts are all polyunsaturated oils!  Yes, flax oil is omega 3 and canola has more omega 3 than omega 6, but both omega 3 and omega 6 are polyunsaturated.

    A yea ago, i went off niacin and zocor due to elevated liver enzymes.  Before I restarted niacin, an NMR lipoprotein analysis showed:
    LDL particle number - 2197
    Small LDL-P - 1614
    LDL Particle size - 20.3
    Saturated fat (% of calories) - 21%

    Six months later, after radically increasing the amount of coconut oil I consumed, the results were:
    LDL particle number - 896
    Small LDL-P - 466
    LDL Particle size - 21.6
    Saturated fat (% of calories) - 45%


    Five months after that:
    LDL particle number - 946
    Small LDL-P - 120
    LDL Particle size - 21.1
    Saturated fat (% of calories) - 52%

    Carbohydrate consumption has held fairly steady at 10% of calories.

    I agree 100% with these comments.  Not a drop of dogma in them; pure science.  Yes, omega-6 is evil; avoid foods with any of it. No nuts, no seeds. Soy -- dangerous.  Milk -- cavemen didn't drink it and it's possibly dangerous too.  Vegetables -- no, no, goodness no, they're mostly made of dreaded carbohydrates, have little fat, an fiber isn't important!  Saturated fat?  I don't know about you, but I'm too scared to go hog wild on it.

    I know, I know!  Let's not eat at all.  That would drive small LDL to 0!  That would end heart disease -- and everything else -- in a flash.

    Or, just maybe, we could be moderate and sensible.  Take some fish oil to balance whatever omega-6 you get in the olive & canola oils and in nuts.  Eat some, but not too much, animal protein, and mostly fish and lean meats at that, because saturated fat isn't out of the woods yet. (Just because saturated fat's risks have been over-hyped doesn't mean that we should eat all meat all the time, because the evidence is not in yet that saturated fat is a panacea.) Eat some, but not tons, of fruits, because they have antioxidants.  And for goodness sake, eat your vegatables -- lots of them, and all kinds of them -- because your mother was right to make sit at the table until you finished them.

    Lastly...I have a question for Dr. Davis:

    Dr. D., is this "genetic small LDL" the same as when you talked about people with ApoE4 in your November 17, 2008 post? If so, do you think it would be helpful to test ApoE before experimenting with diet??

    I'm going to steal a page from T. Colin Campbell here (yechh!)

    Dr Davis, you say that

    "I have indeed had many people with presumed "genetic small LDL" load their diets with oils and fats with only minor improvement. Loaded with saturated fat, however, and there seems to be deterioration."

    Campbell makes the contention that studies showing that low saturated fat intake is beneficial (never mind whether they actually exist or not, just for the sake of argument here) might actually have nothing to do with the type of fat in the diet, and everything to do with the protein which accompanies the fat; most animal fat in our culture comes attached to meat (protein.)

    Adding plant fats and oils to the diet, including nuts, would tend to increase total percentage fat in the diet at the expense of both carbohydrate and protein. Adding animal fat, attached to meat might increase total protein percentage even as it increases total saturated fat.

    Understand, I'm not saying "protein bad," I guess I'm just echoing Peter, really, Stan may be trying to live off of a protein/fat mix that's too rich in protein, entirely aside from the whole issue of saturation.

    Flax oil, canola oil, any nut oil (except macadamia nut oil), and all of those nuts -- these are all rich with polyunsaturated fats. I never eat these oils, and my Lp(a) is 2, as last measured a few months ago.

    I always recommend nuts as a very moderate snack because of their high PUFA content.  Macadamia nuts are the ONE exception, with a fatty acid profile similar to olive oil.  Basically, I never recommend any food with a PUFA content greater that 12 percent.  That means canola oil is right out!

    Dr. Davis, perhaps try putting a few of these presumed "genetic small LDL" people on a real low PUFA diet for a while (with more coconut oil and butter--but no nuts during this period) and see if there's improvement.

    I'd bet there is.  Nothing really to lose by giving this a shot.

    Some other features of the presumptive "genetic small LDL" pattern:

    1) It occurs in the minority of people with small LDL, likely less than 20% of people who start with substantial small LDL.

    2) It is associated with insulin resistance and a tendency towards diabetes

    3) It can occur independent of ApoE genotype. However, if it occurs with ApoE2, it means a very potent carb-sensitivity/diabetic tendency.

    4) The "floor" of 600 nmol/L can be broken. We've had success achieving really low body weight and inconsistently with several supplements, e.g., phosphatidylcholine.

    This area is fascinating, though very poorly explored. "Genetic small LDL" is truly one of the problem areas in gaining control over heart disease risk.

    I would like to add support to Dr. Harris' hypothesis. LDL (no NMR in our country) and TG both rise on low carb, high sat fat diet. No weight problem ever. No high protein no high PUFA for me. Pre-diabetic fasting glucose (110-120). Only complication is I had my gallbladder removed (but my brother didn't). Will increase coconut oil and olive oil on account of double cream. Feel so good on low carb it can't be wrong. Also wonder if under healthy low carb diet LDL and TG have atherogenic effect (My calcium score is low)
    In summary I think Dr. Davis is onto something but I would love to know if LDL status corresponded to increased calcium score in the said patients.

    Choline deficiency can lessen hyperglycemia in rodents with fatty livers. Maybe the inconsistent effects of phosphatidylcholine have something to do with that?

    To the person who mentioned the saturated-fat mafia; we have limited information going in here. Trying to guess at alternate explanations isn't the same as insisting that saturated fat is good in all situations for everybody, no matter what. Proper skepticism demands that we question even the most respected sources.

    Dr. Davis, this recent article seems congruent with some of your observations:

    To all these nutty omega-6 fatphobes - I eat lots of nuts of all sorts, probably 40% of calories, including... peanuts, which I am aware are a legume.  I have no small LDL, undetectable CRP, and lp(a) of 4, high hdl and low homocysteine, HbA1C of 5.2.

    Dr. Davis,
    You said "Some other features of the presumptive "genetic small LDL" pattern:

    1) It occurs in the minority of people with small LDL, likely less than 20% of people who start with substantial small LDL."


    So, based on a minority of people with small LDL, you are recommending the same diet to everyone?

    Please don't misunderstand: I am NOT saying that saturated fat increases small LDL in most people.

    What I am suggesting is that there is a genetic minority in which saturated fat increases small LDL. These people seem to be the unusually slender, high HDL, low triglycerides, yet diabetes-prone who show apparently intractable small LDL.

    I don't know for a fact why this happens, but I speculate that it is a genetically-determined trait.

    This pattern responds best to a high-protein, high-fat, very low-carbohydrate diet. But saturated fat is the exception in this group.

    Hello Dr Davis

    I am only persisting in this as the implications might be important.

    I asked, "Did you advise Stan to increase sat fat and then watch his sdLDL get worse?"

    You later said, "Loaded with saturated fat, however, and there seems to be deterioration."  and ..

    "What I am suggesting is that there is a genetic minority in which saturated fat increases small LDL."

    and...

    "This pattern responds best to a high-protein, high-fat, very low-carbohydrate diet. But saturated fat is the exception in this group."

    Can I assume when you say "seems to be deterioration" and "there is a suggestion that saturated fat increases small LDL" and "saturated fat is the exception" that this is based on the observation of  serially increased sdLDL NMR values after increasing only saturated fat intake in these 100 or so patients?

    If this is what you have, serial NMRs that show increased sdLDL with increased saturated fat intake, why not say so explicitly?

    Or is it just a reasoned (perhaps correct, perhaps not) guess of what would happen to sdLDL in those 100 or so who have this presumed genetic pattern of persistent sdLDL?

    Dr. Davis wrote:

    "I know this flies in the face of the 'saturated fat is great' dogma, but I don't make this stuff up."


    The way that Peter described the scenario you presented, it seems to support the health benefits of saturated fat rather than deride them

    Ollie is mainlining saturated fat from his gut.  Stan is not.  Ollie's sdLDL drops like a rock.  Stan's doesn't.  

    It seems like if this phenomenon of high sdLDL specifically affects low BMI people, their lack of saturated fat intake, whether through their mouths or from their love handles, could be the culprit.

    Dr. Harris,

    I'm a fan of your blog, but I can't help but notice that you have completely ignored Dr. Harris's questions in this entry as well as the other recent entry about saturdated fat and LDL.  I find his questions to be pertinent.

    I'm actually a little surprised no one's brought up this blog, that indicates polyunsaturate consumption over 4% of calories can be detrimental:

    http://wholehealthsource.blogspot.com/2009/05/eicosanoids-and-ischemic-heart-diseas.html

    Eh. Took me long enough to find. At any rate, 10-20% polyunsaturates, especially if they come from omega-6, is a huge amount for a human.

    Imma going to go away and let you argue now.

    My family has a history of high colestral and plaque build-up in the blood.  Should I stay on my Lipator and stay on a low-carb diet ?  Your article brings up some red flags for me.  Maybe I should talk to my Doctor, but my low-carb friends tell me the doctor will tell me to get off the diet !  I would like some advice.

    How did that happen? Is it possible? Different diet will work to Stan? I am curious about that. I will visit this blog again. I am hoping for an update.

    Obviously another great blog about eating and living right, but at some point we have to take a step back and live.  Food avoidance and constant stressing about food seems it could negate any benefits of just eating a sensible, well balanced, moderately low carb diet.  

    To me, all these nutrition blogs are fun to read at work. But have you ever noticed the incredible difference in opinion from one to the next?  I take all that with a large grain of salt, pun intended.

    Oh my god, I ate a walnut, surely I will be in the cath lab tomorrow getting my LAD stented;)

    You might not find yourself in the cath lab from eating the random 1/2 cup of oatmeal, but you might find yourself there from stressing about it too much.

    Read all the blogs, use all the information to help guide you.  But don't get in line with the zombies and wander off the deep end too far.

    Just a thought.

    Here's a stumper. I just had my VAP done and the results surprised me. Some background: I'm not on any medication and never have been. Never had a weight problem, body fat below 20%. I exercise regularly (CrossFit 4x/week). Never smoked. Rarely drink. I eat mostly a primal diet w/plenty of grass-fed/organic/cage-free/wild-caught meat/fish and lots of fresh veggies. Some dairy, but only hormone and antibiotic free. Hardly any grains or processed foods. Low fasting blood sugar (76 as of two weeks ago.) Here are my VAP results:

    Total cholesterol: 200
    HDL : 79
    LDL: 106
    VLDL: 14
    Lp(a): 7
    Triglycerides: 43

    With all that I'd expect to have Pattern A LDL. Yet the VAP test says I have Pattern B! I'm not aware of any history of heart disease on either side of my family. But if it's true that my LDL is small and dense, all I can figure is that it must be genetic. I'm not really sure what to make of it! Any ideas?

    Liz Stanley - while my HDL and LDL aren't as good as yours (63 and 185 respectively), I also just received VAP results that stumped me for a similar reason.  I exercise frequently, am not overweight, don't smoke or drink, eat low carb, etc., yet I have pattern B as well.  To add to the confusion, my cCRP is 0.7, which my doctor said was excellent and basically renders my test results a wash as I have zero other risk factors.  I don't know what to make of any of this when you put it all together, and I stumbled upon this post because I'm hoping to find some answers online.

    While body composition certainly isn't a prerequisite for being part of a classic comedy team, I couldn't help but notice that Stan had the makings of a skinny-fat bean pole checking in at 5' 10" and only 148 pounds. Those stats make him sound like a diehard distance runner or a chain smoker.
