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.

Butter and insulin

Butter and insulin

In a previous post, Atkins Diet: Common Errors, I commented on butter's unusual ability to provoke insulin responses. I offer this as a possible reason why, after a period of effective weight loss on a low-carbohydrate program, inclusion of some foods, such as butter, will trigger weight gain or stall weight loss efforts.

This develops because of butter's insulin-triggering effect, doubling or tripling insulin responses (postprandial area-under-the-curve). If insulin is triggered, fat gain follows.

Here's one such study documenting this effect: Distinctive postprandial modulation of ß cell function and insulin sensitivity by dietary fats: monounsaturated compared with saturated fatty acids

López et al 2008


From Lopez et al 2008. Mean (± SD) plasma glucose, insulin, triglyceride, and free fatty acid (FFA) concentrations during glucose and triglyceride tolerance test meal (GTTTM) with no fat (control), enriched in monounsaturated fatty acids (MUFAs) from refined olive oil (ROO meal), with added butter, with a mixture of vegetable and fish oils (VEFO) or with high-palmitic sunflower oil (HPSO). N = 14.

The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

Fat, in general, does not make you fat. But butter makes you fat.

    I wander if the effect is due to the milk solids or the type of fatty acids. If it is the milk solids making ghee will solve the problem.

    So the low fat control meal of pasta and bread gives the LEAST amount of insulin response!

    So, to avoid insulin spikes you must minimize all types of fats.

    Fat+Pasta seem to trigger the insulin.  The glucose response does not seem to matter all that much.

    Thanks for the great info as always.

    Is it correct to say, in view of the graphs, that this type of dairy-induced insulin elevation is not mirrored by blood glucose readings, so we couldn't check for it at home with a glucose meter?

    butyric acid causes an insulin response, as does casein...interestingly, although i can't find it, i saw a paper that showed the insulin response to white bread was actually less when combined with butter...

  • daniel the smith

    3/19/2010 6:06:21 PM |

    What if you eat it without any carbs (e.g., like I do with my eggs in the morning)? If there's nothing to trigger the insulin in the first place, butter can't make it worse, right? Or am I wrong?

  • Lucy

    3/19/2010 6:16:20 PM |

    That's an interesting study indeed.  It seems to indicate that eating no fat at all (the control meal) provided better results in every category except glucose rise, and then it was only with the rest of a fairly tight pack.  Adding any fat at all spiked the insulin significantly higher.   This is consistent with the charts in your post "The Timing of Blood Sugars".  Yet you concluded there that carbohydrates should never be consumed without fat.  Based on these studies, it sure looks like a person is trading a little glucose rise for a larger insulin spike when consuming fat.  Which begs the question, which is worse?  Does insulin cause more problems than glucose?   You did say it was the insulin that triggered weight gain...

    I remain unconvinced that I should rush out and follow Ornish.

    Interesting post -- and my experience confirms it.  Here's something that I recently posted to the OEvolve e-mail list:

    As folks might know, I've been struggling with my weight due to my hypothyroidism.  Even though many of my symptoms have improved, I continued to gain weight at the very consistent rate of 3 pounds per month.  Sometimes, mostly due to a bit of fasting, I'd be down a pound or two, but then I'd suddenly gain back all that weight plus more within a day or two, so that I'd be on that steady upward slope again.  

    In late February, I was up to just over 150 pounds; that was my pre-paleo weight.  That's not so terrible in and of itself -- although I hated it -- but the continued upward progression was really alarming.  Plus, I'd outgrown almost all my pants!

    After listening to Robb Wolf talk about the growth-promoting, insulin-spiking effects of dairy, I realized that I'd been eating a huge amount of dairy lately -- far more than ever before.  I've been buying those huge blocks of cheese from Costco, not to mention those delectable half gallons of cream.  So instead of eating meat-and-veggie leftovers for lunch, I was usually eating some high-fat dairy.  And for breakfast, I would eat cheese rather than meat with my eggs.  

    A few weeks ago, I decided to cut my dairy down dramatically -- to basically just one serving per day at most.  So I'll have a cup of raw milk kefir or cheese on meatza, but not much more than that.  That was really hard for me to do for the first week, as I really was used to eating it as a staple.  I'm also not eating nuts, absent some "must have food as I run out the door" emergency, as I know they can hamper weight loss for me.

    The results have been good so far.  I've not gained any more weight in the last two weeks.  Instead, I've lost four pounds.  Given what I had been experiencing, that's pretty remarkable.

    I'm not sure how much more weight I'll lose just due to cutting back the dairy.  I definitely think my metabolism isn't quite up to speed yet due to the hypothyroidism. However, my experience suggests that eating boatloads of dairy -- even good-quality, high-fat dairy -- is an excellent way to gain weight.

    That being said, I don't think that it's necessary to cut out all dairy to lose weight.  I'm still eating some dairy, and I'm losing weight.  Plus, I lost my original 18 pounds with my 1.5 shares of raw milk -- that's 1.5 gallons per week.  (I'm now down to just 1/2 shares, meaning 1/2 gallon per week.)  I just think dairy is something to consider reducing if you're not meeting your weight loss goals.

    ***

    I've not lost much more weight since writing that, but I'm definitely not gaining any weight.  That's huge: I was petrified that I'd be 200 pounds by next summer.  

    I've probably stalled in that weight loss because my metabolism is still screwy due to my not-yet-fully-managed hypothyroidism.  Plus, I'm not seriously trying to lose weight right now: I don't want to stress my already over-stressed body.  But perhaps cutting out dairy entirely would make a difference.

    Anyway, thanks for putting some science behind my experience, Dr. Davis!  I'll definitely add a link to it in the discussion of dairy on the principles page of Modern Paleo.

    Could butter still make you fat if you're eating below BMR?  It seems to me that if you were eating 1000 calories per day consisting of only butter, and your BMR was 1800, you would still lose weight.  Is there anything that scientifically proves this to be false?

  • Nostril Damus

    Dear Dr Williams, I find this topic very interesting, but being a lay person would like to know a bit more. What would the "meal" they talk about be? Would that be grains? Is the resuls they got from combining grains with cream or butter? Would butter or dairy products have the same effect in the absence of grains?

  • Donald Duck

    3/19/2010 9:35:38 PM |

    Doesn't this study mainly show that butter is a bad idea when eaten together with lots of carbs?

    Is it really likely you would get the same insulin response if the butter was eaten without all that carbs?

  • Mark

    After removing dairy, grains, and anything else processed. I'd imagine it would be hard to eat too many calories when all you're left is meat, veggies, and fruit but not too much. Just curious, is that all we have to choose from?

  • K Walt

    3/19/2010 10:26:25 PM |

    Interesting.

    But the meals were carb-heavy, too.

    "The subjects then ingested, within 15 min, a fat-rich meal consisting of dietary fat [50 g/m2 body surface area of butter, refined olive oil (ROO), high-palmitic sunflower oil (HPSO) or a mixture of vegetable and fish oils (VEFO) along with a portion of plain pasta (30 g/m2 body surface area), one slice of brown bread, and one container of skim yogurt.

    I wonder if the same effect would be noted if were JUST butter, or oil.

    Is it the butter? Or the wheat pasta, brown wheat bread and lactosey yogurt?

    3/19/2010 10:26:26 PM |

    Interesting. Here are the numbers from the study for insulin AUC:

    19960 +- 2766 control
    27970 +- 2107 VEFO
    29619 +- 4975 MUFA
    34749 +- 1167 HPSO
    37582 +- 4364 SFA (butter!)

    Unless I've misread the study, the "control" meal has no fat at all, and is not isocaloric with the test meals. "the macronutrient profile was as follows: 72% fat, 22% carbohydrate, and 6% protein (see Table S1 under "Supplemental data" in the online issue). The subjects also consumed the same test meal containing no fat as a control meal". So the butter test meal has nearly 4x as many calories as the control meal. The AUC for insulin between the two is about double for the butter, but that seems like a useless measure.

    Comparing like-for-like, the spread between average insulin AUC for butter meal and the isocaloric alternate fat meals  shows the butter to be about 34% higher than VEFO and only 8% higher than HPSO. (I have to be pedantic here and point out the spread between averages is not as good as would be the average spread, but I can't get that unless I have the raw data from the study.)

    If you want to claim that butter has some unique ability to raise insulin vs. other fats, this is not strong support.

    You say "butter's insulin-triggering effect, doubling or tripling insulin responses", and "butter makes you fat". I don't see support for either claim when I read that study.

  • Beth@WeightMaven

    3/19/2010 10:58:06 PM |

    I'm not an MD nor a research scientist. But decades ago, I was a math major. If I read the study and do my math right, the subjects ate an 800 kcal meal of which 72% was fat, for 576 kcals worth of fat (the other control meal components were pasta, bread, and skim milk yogurt).

    576 kcals worth is nearly 6T of butter -- or 3/4 of a stick! To me, that is important additional context for the increased AUC for both the insulin and the triglycerides.

    Considering my typical use (~1T/meal) and considering the potential downside of replacing carb calories with more PUFAs (and omega 6s -- even 1T of EVOO has over 1g of omega 6), I'm not ready to throw out my ghee just yet.

    This study is not meant to stand on its own, but taken in the context of other studies.

    I think that you should eat butter . . . in small quantities and occasionally. I do not believe that the data argue for liberal use every day, or else you chance triggering insulin. Remember: It's the interpretation of the data in the context of the broader experience that leads you to practical conclusions.

    So let me get this straight: Ingesting carbohydrates including the bad guy wheat does not do much to blood glucose levels and insulin response. But adding fat to the mix at least doubles, or, in the case of butter, quadruples the peak insulin response? That seems like the best refutation of all the low carb/paleo/primal/ef approaches I've ever seen. So where is the catch?

    If you eat fat, ASP levels will rise, which will make you gain fat. ASP levels increase in response to an oral fat load, and ASP is one of the most potent stimulant of triglyceride synthesis.

    So, if you eat carbs, insulin secretes and you store it as fat, if you eat fat, ASP levels rise and you store it as fat. Why is it only the insulin's fault?

    "Fat, in general, does not make you fat. But butter makes you fat."

    This seems wrong. When I eat more butter, I lose fat/weight. Eat more carbs, gain fat/weight. Been noticing this for years. Sure, put a load of butter on noodles or rice, and you'll gain plenty, but just keep the carbs low and there's no problem. This seems like a case of being blinded by science. Maybe the science isn't exactly wrong, but just incomplete or misapplied.

    After reading your post and the hyperlipid post I'm left with a few questions.

    1.The big one, why is butter raising insulin so much? I had previously thought it was only high GI carbs that did that. Hyperlipid seems to think it was the small amounts of casein.

    2.Is it right to say that since the control carb meal only contained 174 calories compared to the butter meal which contained 800 this study is fairly useless? It raises some interesting questions but you can't conclude anything until you have a proper control containing the same amount of calories.

    3. Are there any studies which measure insulin secretion after a pure butter meal with no carbs?

    Even though the study is inconclusive, I'm lowering my butter consumption until I'm sure it isn't causing an agrovated insulin response. Even though butter causes much higher levels of FFA's which mean more of the fat is being burned, insulin levels that high can't be healthy

    All this information hurts my brain...ugh. All I know is when I eat low carb... I lose weight... feel better and more energetic. Sometimes there's just too much analysis and information about what constitutes a healthy diet. It's all opinion and based on research. Then other research refutes that idea.

    Dr. Davis,

    I'm not too sure this is right.  I don't have the time to hunt down the links right now, but there was a study on Swedish children recently that showed those eating full-fat dairy (butter fat) were leaner than those who ate low-fat dairy.  Also, butter contains a lot of CLA, which is now being sold as a fat-loss supplement.  I can't parse this study on its own merits like Peter or Pyker (though I thank them for doing so), but I remain unconvinced.  

    I also agree with other posters about the in-vivo, long-term evidence of dairy-reliant cultures and their longevity.  

    Again, with so many cautions of what not to eat, I'd love to see a Dr. Davis-approved diet plan.  If I were just following all the Don'ts, I'd go crazy (and hungry).

    The palmitic acid content of the butter would probably trigger  insulin when there is an abundant source of glucose in a meal.  But, if you look at this post by Stephan you will see that the body stores dietary fats when there is a glucose source of energy available.  

    http://wholehealthsource.blogspot.com/search/label/fats

    As the glucose is depleted the fat is released to be used as energy.  The graph in Stephan's post clearly shows the cycling that occurs in normal metabolism.


    The information Dr. Davis presented showed an insulin spike, not continual high levels of insulin that would inhibit the release of FA as an energy source.
    I believe it was Dr. Eades who recently posted about the constant exchange of fats in and out of storage, and the implication is that storage is only a problem when cells remain saturated with glucose.  The fat never comes out because it isn't needed.  In this scenario insulin resistance and fat storage is protective.

    http://high-fat-nutrition.blogspot.com/2010/03/getting-fat-is-good-official.html

    My understanding of this subject is, by limiting carbs, especially the sugar surrogates that are refined grain products, you can keep the normal cycling of energy sources going.

    When everything is working right, your body signals hunger and satiety appropriately, and the body runs at an equilibrium level of energy intake and energy expenditure.

    I suspect that the FA composition of butter makes it available as an energy source sooner than the other FA's tested in the study.  Hence the higher insulin level.


    I don't see where a moderate amount of butter, when there is a limited or low availability of glucose sources will make you fat, expecially if you are VLC or on a ketogenic diet.  I can see where it could be a problem if you were eating 150 or more grams of carbs per day and have metabolic syndrome.  Then high levels of insulin would spike even higher prompting the liver to pump out more glucose, and the fat just has no where to go except into storage.

    Take your vitamin D3 to get your adiponectin levels up.  Take fish oil while limiting Omega-6's to normalize inflammatory responses. Limit carbs, and get the glucose-FA cycle working for you.

    Eating carbs with butter produces a big insulin response because butter induces temporary insulin resistance (IR) which means that more insulin has to be secreted to get the same net effect. Looking at the blood glucose response, the net effect is the same. So stop panicking. The temporary IR lasts for only a few hours.

    "Fat, in general, does not make you fat. But butter makes you fat."

    If you based your conclusion on the graph in this study, all fats make you fat.

    Protein also stimulates insulin, so protein makes you fat.

    Carbs stimulate insulin, so carbs make you fat.

    Conclusion: Food makes you fat.

    It's known that fatty acids acutely stimulate insulin synthesis. With chronic exposure to fatty acids (as occurs in obesity), insulin synthesis is blunted.

    I've never understood the body's rationale for this, unless a sudden infusion of fat makes it think it had better store the fat for the future, but with chronic stimulation it figures it has enough.

    I don't know how ingested fat is related to fatty acids in the blood, whether or not this is linear.

    Whatever, it doesn't look to me as if butter is much different from the other fats, and as others have pointed out, the amounts used in this study (on top of about 44 g of carb, which I wouldn't call a low-carb meal) were enormous.

    The other odd thing is that usually fats slow down a carb-stimulated blood sugar peak, and they didn't in this study.

    This is what is considered 'butter' in the study you refer to above Dr Davis and ultimately what this study uses to prove its point:

    "The subjects then ingested, within 15 min, a fat-rich meal consisting of dietary fat [50 g/m2 body surface area of butter, refined olive oil (ROO), high-palmitic sunflower oil (HPSO) or a mixture of vegetable and fish oils (VEFO) along with a portion of plain pasta (30 g/m2 body surface area), one slice of brown bread, and one container of skim yogurt]."

    Yep, that would be my definition of 'butter' as well!

    If that pile of c**p didn't raise your insulin levels what would?

    In addition: "The average total energy provided by the meals was 800 kcal (10 kcal/kg), and the macronutrient profile was as follows: 72% fat, 22% carbohydrate, and 6% protein"

    Only 22% carbohydrate, no chance of that increasing insulin levels either I suppose!

    It has to be the 'butter'

    @Helen: I found the study you are referring to I believe.

    "BMI correlated strongly to fat mass and leptin was the best marker of overweight and fat mass in 8-year-olds. Food choice was similar to that at 4 years of age. An intake of fat fish once a week was associated with higher serum concentrations of n-3 fatty acids. The intake of saturated fat and full fat milk were inversely associated with BMI."

    The study was made at the University of Gothenburg.

  • Mike

    Looking at insulin alone can be very misleading. If glucagon is released along with the insulin ,as happens when eating protein, then the fat storing effects of insulin are negated.

    For low carbers, the study is meaningless as it was done with lots of carbs. I will continue to eat butter and cheese until I see a meaningful study that shows that they cause a real problem.

    I saw it, and was hoping to discuss it in the pro-D blogosphere.

    I have two ideas why this might be the case.

    (1)  Because people of African descent are adapted to live nearer the equator, where the sun is all you need for enough vitamin D, they may not be as adapted as Europeans to use dietary vitamin D (supplements being an analogue), which Europeans probably relied on during winter months.  Thus, too much supplemental vitamin D may be harmful to African Americans, at least in the case of arterial calcification.  (I hedge, because I've also read recently that African American children with low D status have higher rates of asthma. http://www.sciencedaily.com/releases/2010/03/100317112055.htm)

    (2) There is also the possibility that somewhat different dietary patterns between European Americans and African Americans may offer some explanation.  I can't imagine what this might be, but maybe something having to do with vitamin K2, which helps prevent calcium deposits in the arteries?  There are two possibilities here:

    (a) Maybe African Americans consume (or produce in the gut - from eating greens, a traditional part of the African American diet) more K2 than European Americans, and this is why they have less arterial calcification with lower D status - they don't need the D as much for arterial health, and more dietary D just upsets the balance.

    (b) Maybe they eat less K2 than European Americans (maybe eat less hard cheeses?), and thus vitamin D supplementation, which may require a certain level of K2 to be beneficial, might be harmful instead.

    This sentence leads me to believe it's more likely to be (a):  "Despite these lower vitamin D levels and dietary calcium ingestion, blacks naturally experience lower rates of osteoporosis and have far less calcium in their arteries."  The strong bones and clear arteries make me think African Americans may have better K2 status.  

    It's possible that vitamin A status also plays a role.

  • Helen

    3/21/2010 8:56:30 PM |

    Another thought on the question of African Americans and vitamin D - perhaps *because* they consumed less calcium their vitamin D requirements were lower, so the supplemented amounts were excessive.

  • Dr. William Davis

    3/21/2010 9:55:55 PM |

    The point is not whether glucagon is stimulated. That is, in my view, immaterial.

    The point is that your poor, tired pancreas, likely operating at a fraction of its original beta cell capacity from the years of the beating it took while you ate Cheerios and Cocoa puffs, ate sandwiches, and drank Coca Cola with your pizza, is being stimulated to produce more insulin.

  • Nigel Kinbrum

    3/22/2010 9:05:25 AM |

    Regarding calcification, I think that Helen has hit the nail well & truly on the head regarding Vitamin K2. "If it calcifies, think K2" is what I always say (along with "If it spasms, think Magnesium").

    Taking large amounts of Vitamin D3 and nothing else probably exposes deficiencies in the other fat-soluble vitamins A, E & K2.

    Having cured Lumbar osteoporosis in three years using Ca, Mg, D3 & K2 (and no Alendronate), I will never stop taking Ca, Mg, D3 & K2.

    Why eat carbs together with fat?
    They ate 44 g glucose which means the P-glucose could reach >48 mM without insulin i 70 kg person. Of course the disaster hormone insulin increases to block all lipolysis as well as proteinolysis to try to burn off all the totally unnecessary carbohydrates they added.
    If contol diet (gluose) did not change glucose and thus insulin level it must be fake.

    Just another totally stupid study.

    Ingesting air is the only thing that will not make me fat.

    When I'm low-carbing, a favorite meal is a tenderloin cooked medium-rare, sliced thin, and dipped in butter.

    I lose weight anyway.

    Also, what kind of butter was used in the study?  Was it regular grocery-store butter, or was it organic and/or grass-fed butter?  The FDA claims there's no difference between dairy produced with rBGH and dairy produced without, but I'm given to understand that rBGH-produced dairy has higher levels of IGF-1.  What would be the effect on insulin of all that exposure to insulinlike growth factor?

    And I'll second Miki's question of whether the milk solids wouldn't make a difference.

    And to the person who mentioned "all that lactose-y yogurt"--if you make yogurt correctly, it should have hardly any lactose in it at all.

    I suspect that the FA composition of butter makes it available as an energy source sooner than the other FA's tested in the study. Hence the higher insulin level.

    Fatty acids by themselves don't prompt insulin release.  Protein does (but the insulin is balanced out by glucagon), and of course carbs do, but there's nothing inherently dangerous in a fatty acid that would prompt the body to store it away immediately.

    It seems like no one has a handle on how the metabolic parts fit together to make the whole. My experience from converting from whole grains and no-fat dairy to full-fat dairy has been weight loss and increased energy, particularly after eating a selection of artisan cheese. I often get up, have a bowl of full-fat yoghurt or kefir with 100% chocolate nibs and fresh-roasted nuts, then sample several artisan cheeses, and go cycling 44 km before getting back to make everyone else breakfast. My body seems geared to fat as fuel and I never get blood sugar lows. If this is raising my insulin, it apparently does not affect my blood sugar.

    Usually, I learn all I need to from Dr. Davis' posts.  My thanks to the other contributors today for illustrating that context is everything.  We have reason to believe that dairy from the industrial food chain would not be as good a food as if we could get true grass fed dairy cow products - but this seems out of context with other info I've seen which shows only moderate insulin response to dairy fats.  Bottom line: measure the markers which indicate insulin levels over time as a gauge of whether your diet does/doesn't work (unless you are losing weight - in which case, you know it is working).

  • Anna Delin

    It seems that whatever butter does to my insulin levels, this does not curb the very positive effects I experience from eating butter. When I cut carbs and replaced them with generous amounts of cream and butter (organic preferably) I lost 14 kg. Moreover, when in "carb country", i.e. airports, airplanes, trains and the like, I can keep my energy up by eating the small amounts of butter and cheese available. Butter also has a way of keeping me feeling full for a very long time. This implies that the fat is not stored away in my fat cells but instead made available for burning. Perhaps other people are more sensitive.

    I still prefer coconut oil for fat loss used in a no-carb diet. I'll find that ghee, which I've also tried, isn't so effective for weight-loss perhaps because it's not so fatty. But it does have to be in a no-carb diet, not a low-carb one. Everyone's got a switch which is triggered by carbs, but no-one knows where it is, not exactly. So unless a study is rabidly no-carbs, none at all, I don't really see what can be learned.

    Dr William
    your response to the commentors seems to indicate that butter will make you fat IF you have abused your body with carbohydrates because of a compromised pancreas.  I am willing to suppose this could be true, but what about people who his ave not abused their bodies, what about children being raised low carb from the start, would butter be fattening for them?  Your response would lead me to believe your answer will be no.  I really appreciate your blog and recommend it to all, but please clarify this issue.  Maybe a whole new blog on this would be a good idea, since the entire low carb community is talking about it.

    To everyone else I have to say there is nothing like testing something for yourself.  If you have an insulin tester, have some butter and test yourself and make a chart.  See how YOU are affected.

    The work was funded by the Fundación Centro de Excelencia en Investigación sobre Aceite de Oliva y Salud (“Center of excellence for research on olive oil and health”).

    Notice that they end up concluding that olive oil raised glucose and insulin less than butter. Had this study been done by French researchers and not Spanish researchers, it would have found that butter is better for you than olive oil!

    The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

    Um... Sorry... I see the data differently.
    In the fat meals in the study, the amount of fat intake was the same, yet butter delivers higher serum FFAs, indicating that fat might stimulate lipolysis, even though it appears to induce a short term insulin spike.
    Carbohydrate might promote a lower insulin response, but it blocks lipolysis.
    Finally, there's a lot more going on here than just insulin.  To take it out of context is meaningless.

    There is another problem with that study - people do not keto adapt in 8 hours - it takes 4- 6 weeks to fully adapt to a low carb diet.

    Once adapted, low-carbers are BETTER able to clear FA as the liver revs up it's fat metabolic capabilities.  Low carbers also tend to eat less frequently - reducing the exposure to both BG and FA - only when both are elevated do we see the pronounced toxic effects of the fats.
