Increased blood calcium and vitamin D

Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

Heart health consultation with Dr. Joe D. Goldstrich

Cardiologist, nutritionist, and lipidologist, Dr. Joe D. Goldstrich, is a frequent contributor to the Track Your Plaque Forum, where we discuss the full range of issues relevant to coronary health and coronary plaque reversal.

I have come to value Dr. Goldstrich's unique insights, especially in nutrition. Formerly National Director of Education and Community Programs for the American Heart Association and a physician at the Pritikin Center, his dietary philosophy has evolved away from low-fat and towards a low-carbohydrate focus, much as we use in Track Your Plaque. Like TYP, Dr. Goldstrich is always searching for better answers to gain control over coronary health. His unique blend of ideas and background has helped us craft new ideas and strategies. Dr. Goldstrich has proven especially adept at understanding how to incorporate new findings from clinical studies in our framework of coronary atherosclerotic plaque management strategies.

Dr. Goldstrich is offering to share his expertise with our online community. If you would like a one-on-one phone consultation with Dr. Goldstrich, you can arrange to speak with him at his HealthyHeartConsultant.com website.

Wheat aftermath

Following my 4 oz whole wheat misadventure that yielded the sky-high blood sugar of 167 mg/dl, compared to einkorn wheat's 110 mg/dl, I suffered through a 36-hour period of misery.

After I obtained the blood sugar of 167 mg/dl, I biked hard for one hour. This yielded a blood sugar back down in the 80s. I felt spacey in the ensuing few hours, as well as a little queasy. However, about 12 hours later, I awoke with overwhelming nausea along with that hypersalivating thing that happens just prior to vomiting. It did not come to that, but persisted all through the following day.

The next morning, I could barely concentrate. Trying to read a study (admittedly on the complex topic of agricultural genetics), I had to read each paragraph 4 or 5 times. Abdominal cramps and a bloated feeling also developed, though I was able to eat.

The 2nd night was filled with incredibly vivid dreams and intermittent sleeplessless. I awoke about 5 times through the night, but periods of sleep were filled with detailed, colorful dreams. I dreamt that a large corporation was secretly trying to gain control over the world's water supply, and I snuck onto a complex underwater vessel that was exploring and mapping the coastline of the Great Lakes in preparation. Weird.

I recognized these odd feelings as various facets of wheat intolerance, since they were all reminiscent of feelings I used to experience before I removed wheat from my diet. They were amplified and compressed, likely because I had been wheat-free for so long.

The odd thing is that, despite the modest blood sugar effect of my einkorn experience, none of the gastrointestinal or neurologic effects of wheat developed. So far, two other people with acute gastrointestinal wheat sensitivities have consumed our einkorn bread, also without reproduction of their usual symptoms.

Einkorn contains gluten, though the structure of the many gluten proteins of einkorn differs from that of the wheat bread I consumed, an example of modern Triticum aestivum. 14-chromosome einkorn carries what biologists call the "A" genome, while Triticum aestivum has the combines genomes of 3 plants, the combination of the A, B, and D genomes. It is the D genome that contains the genes coding for the most obnoxious, immunogenic forms of gluten.

So einkorn may not be entirely benign, but it is a good deal less obnoxious than modern Triticum aestivum.

I am awaiting the reports from a few other people on their experiences.

In search of wheat: Einkorn and blood sugar

There are three basic aspects of wheat's adverse health effects: immune activation (e.g., celiac disease), neurologic implications (e.g., schizophrenia and ADHD), and blood sugar effects.

Among the questions I'd like answered is whether ancient wheat, such as the einkorn grain I obtained from Eli Rogosa, triggers blood sugar like modern wheat.

So I conducted a simple experiment on myself. On an empty stomach, I ate 4 oz of einkorn bread. On another occasion I ate 4 oz of bread that dietitian, Margaret Pfeiffer, made with whole wheat flour bought at the grocery store. Both flours were finely ground and nothing was added beyond water, yeast, olive oil, and a touch of salt.

Here's what happened:

Einkorn wheat bread:

Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 110 mg/dl

Conventional wheat bread
Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 167 mg/dl

The difference shocked me. I expected a difference between the two, but not that much.

After the conventional wheat, I also felt weird: a little queasy, some acid in the back of my throat, a little spacey. I biked for an hour solid to reduce my blood sugar back to its starting level.

I'm awaiting the experiences of others, but I'm tantalized by the possibility that, while einkorn is still a source of carbohydrates, perhaps it is one of an entirely different variety than modern Triticum aestivum wheat. The striking difference in blood sugar effects make me wonder if einkorn eaten in small quantities can keep us below the Advanced Glycation End-Product threshold.
 

In search of wheat: We bake einkorn bread

With the assistance of dietitian and health educator, Margaret Pfeiffer,MS RD CD, author of Smart 4 Your Heart and very capable chef and breadmaker (previously, before she gave up wheat), we made a loaf of bread using Eli Rogosa's einkorn wheat. Recall that einkorn wheat is the primordial 14-chromosome wheat similar to the wild wheat harvested by Neolithic humans and eaten as porridge.

The essential question: Has wheat always been bad for humans or have the thousands of hybridization experiments of the last 50 years changed the structure of gluten and other proteins in Triticum aestivum and turned the "staff of life" into poison? I turn to einkorn wheat, the "original" wheat unaltered by human manipulations, to figure this out. While einkorn wheat is still a source of carbohydrates, is it something we might indulge in once in a while without triggering the adverse phenomena associated with modern wheat?   

Here's what we did:

This is the einkorn grain as we received it from Eli's farm. This was enough to make one loaf (approximately 3 cups).











The einkorn grain is a dark golden color. I tried chewing them. They taste slightly nutty. They soften as they sit in your mouth.





Here's Margaret putting the einkorn grain into the electric grinder.









We tried to grind the grain by hand with mortar and pestle, but this proved far more laborious than I anticipated. After about 15 minutes of grinding, this is what I got:



Barely 2 tablespoons. That's when Margaret fired up the electric grinder. (I can't imagine having to grind up enough flour by hand for an entire family. Perhaps that's why ancient cultures were thin despite eating wheat. They were just exhausted!)

We added water, salt, and yeast, then put the mix into an electric breadmaker to knead the dough and keep it warm.

We let the dough rise for 90 minutes, much longer than conventional dough. The einkorn dough "rose" very little. Margaret tells me that most dough made with conventional flour rises to double its size. The einkorn dough increased no more than 20-30%.

The einkorn dough also distinctly smelled like peanut butter.





After rising, we baked the dough at 350 degrees F for 30 minutes. This is the final product.

Because I want to gauge health effects, not taste, the bread we made had no added sugar or anything else to modify taste or physiologic effect.

On first tasting, the einkorn bread is mildly nutty and heavy. It had an unusual sour or astringent taste at the end, but overall tasted quite good.

Next: What happens when we eat it? I'm going to give the einkorn bread (I've got to make some more) to people who experience acute reactions to conventional wheat and see if the einkorn does the same. I will also assess blood sugar effects since, after all, hybridizations or no, it is still a carbohydrate.



Margaret Pfeiffer's book is available on Amazon:

Ezekiel said what?

Some people are reluctant to give up wheat because it is talked about in the Bible. But the wheat of the Bible is not the same as the wheat of today. (See In search of wheat and Emmer, einkorn and agribusiness.) Comparing einkorn to modern wheat, for example, means a difference of chromosome number (14 chromosomes in einkorn vs. 42 chromosomes in modern strains of Triticum aestivum), thousands of genes, and differing gluten content and structure.

How about Ezekiel bread, the sprouted wheat bread that is purported to be based on a "recipe" articulated in the Bible?

Despite the claims of lower glycemic index, we've had bad experiences with this product, with triggering of high blood sugars, small LDL, and triglycerides not much different from conventional bread.

David Rostollan of Health for Life sent me this interesting perspective on Ezekiel bread from an article he wrote about wheat and the Bible. David argues that the entire concept of Ezekiel bread is based on a flawed interpretation.

"I Want to Eat the Food in the Bible."


Are you sure about that?

Some people, still wanting to be faithful to the Bible, will discard the "no grain/wheat" message on the basis of biblical example. After all, God told Ezekiel to make bread, he gave the Israelites "bread from heaven," and then Jesus (who is called the "Bread of Life"!) multiplied bread, and even instituted the New Covenant with what? Bread and wine! If you're going to live the Bible, it seems that bread and/or wheat is going to play a part.

But this is unnecessary. Sure, the Bible can and does tell us how to live, but this doesn't mean that everything in the Bible is meant to be copied verbatim. Applying the Bible to our lives requires wisdom, not a Xerox machine.

The Bible was written in a historical context, and the setting happened to be an agricultural one. Because of this, the language used to describe blessing spoke of things like fields full of grain, or barns overflowing with wheat. Had the Bible been written in the context of a hunter-gatherer culture, the language describing blessing probably would have been about the abundance of wild game, or baskets full of vegetables. Whatever is most valuable in your time and in your culture is a blessing. God accommodated His message to the culture as it existed at the time. This is done throughout Scripture.

There is a danger, then, in merely copying what the Bible says, instead of extracting the principles by which to live. Take the above example of Ezekiel, for instance. There's a whole product line in health food stores called "Ezekiel Bread" that supposedly copies the recipe given in Ezekiel 4:9. This is from the website:

"Inspired by the Holy Scripture verse Ezekiel 4:9., 'Take also unto thee Wheat, and Barley, and beans, and lentils, and millet, and Spelt, and put them in one vessel, and make bread of it...'"

Believing that this "recipe" has some kind of special power just because it's in the Bible is ridiculous. How ridiculous is it? I'll tell you in a moment, but first let me say that this is why it's so important not to confuse descriptives with prescriptives. Is the Bible telling a story, or is it telling us to do something? We would be well-advised not to confuse the two.

In the case of the Ezekiel Bread, what is going on in the passage? There's a siege going on, with impending famine, and Ezekiel is consigned to eating what was considered back then to be some of the worst possible food. It was basically animal chow. But that's not the worst thing going on in this passage. Apparently, when the makers of Ezekiel Bread were gleaning their inspiration for the perfect recipe, they stopped short
of verse 12:

"And thou shalt eat it as barley cakes, and thou shalt bake it with dung that cometh out of man, in their sight."

Um...what? Well, there was a good reason for this. God was judging His people, and by polluting this really bad bread with dung (which was a violation of Mosaic law; Lev. 5:3), He was saying that they were no different from the unclean Gentiles.

So why would we take this story and extrapolate a bread recipe from it? Beats me. If you were going to be consistent, though, here's what you'd have to end up with:



Let that be a lesson to you. We don't just go and do everything that we see in the Bible.

Low-carb gynecologist

I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March.

Dr. Fox is quiet and unassuming, but had incredible things to say about his experience with carbohydrate restriction in female infertility and pregnancy. While readers of The Heart Scan Blog already know that I advocate a diet free of wheat, cornstarch, and sugar for heart health and correction of multiple lipoprotein abnormalities, it was fascinating to hear how a similar approach seems to yield extraordinary benefits in this entirely unrelated area of female health. Obviously, female infertility and pregnancy are unrelated to heart health, but the extraordinary benefits witnessed by Dr. Fox in this area suggest that some fundamental lessons in human physiology can be learned. The results are so incredible that we are all sure to hear more about this approach as experience grows.

So I tracked Dr. Fox down in his busy Jacksonville, Florida practice to fill us in on some details.

WD: Dr. Fox, could you tell us something about yourself and what led you to use carbohydrate restriction in your female patients?

MF: I have been in practice as a reproductive endocrinologist for 15 years. During that time, I have seen our specialty move from a broad based practice of reproductive endocrinology to a narrow IVF [in vitro fertilization] focus, with patients being pushed through IVF in a cookie-cutter fashion without any emphasis on non-medical therapy.

Our focus has been to remain as a broad practice where we individualize care and attempt in every case to achieve pregnancy short of IVF. Five years ago, this continued quest for better care led us into the insulin resistance, low-carbohydrate metabolic world that has transformed our practice, although our practice offers all aspects of reproductive endocrinology including sub-specialized minimally invasive surgery, and all available infertility options.


WD: I have been intrigued by your comments about improved fertility with the low-carb diet. Could you elaborate on this?

MF: Yes, five years ago, as more information regarding Polycystic Ovarian Disease or Syndrome (PCOD/S) and its relationship to insulin resistance (high insulin levels) was emerging, we had a simple realization. As we've known for some time, insulin stimulates excess male hormone levels in the ovary, which disrupts ovulation and fertility. Then our job was to lower or virtually eliminate high insulin levels. Again, in simple fashion, we looked at physiology and realized that insulin is released only in response to dietary carbohydrates. Thus, elimination of carbohydrates should resolve the problem. This, in fact, is the effect that we have seen.

In our previous approaches to PCOD, we utilized oral ovulation medicines generating pregnancy rates in the 40% range overall. Now, with the nutritional approach, for those patients that follow our recommendations, our pregnancy rates are over 90%! This has dramatically reduced the need for in vitro fertilization in these patients.

To extend this idea further, we first started with relative low-carbohydrate diets, such as the South Beach diet, but quickly realized this didn't produce a metabolic effect. Over time, it has borne out that only the very low-carbohydrate diet (VLCD) approach produces significant metabolic change. Our impression then was that the current U.S. nutritional exposure probably increases insulin levels and that this has a detrimental effect on fertility.

To counter this effect, we now recommend the VLCD to all fertility patients and their spouses. The pregnancy rates do seem much better overall, as well as seeing a reduction in miscarriage rates. For the first time at our national meeting last year, there were three articles that showed improved pregnancy rates in patients without PCOD or insulin resistance in IVF when Glucophage was used. This drug decreases insulin. This supports the idea that our entire population is subjected to fertility-reducing high-carbohydrate diet.

WD: Do you see any other changes in these patients on the diet?

MF: Yes. All metabolic parameters, as well as many common complaints, improve. Cholesterol and triglyceride levels improve, while "good" HDL cholesterol levels increase. Weight drops at a pace of 12 lbs per month very steadily and we have many many patients who have experienced 50lb wt loss. Blood pressure decreases steadily in these patients and we are often able to get them off of cholesterol and blood pressure medicines. Common symptoms such as anxiety, sleep disturbances, decreased energy, migraine headaches and depression all dramatically improve. Again we can often get patients off depression and migraine suppression medications. So this approach helps in a multitude of areas.



WD: I was also interested in hearing more about your experience with morning sickness and the effects of a low-carb diet. Could you tell us more about this? Also, any thoughts on why this happens?

MF: As we continued to expand our thoughts about VLCD and fertility/pregnancy, we began to extend the nutritional approach into pregnancy. We know that pregnancy hormones dramatically worsen insulin resistance that is responsible for the condition, gestational diabetes. If insulin resistance is worsened, then reactive hypoglycemia is worsened. One of the biggest symptoms of hypoglycemia is nausea. So, in response to this, we have counseled our patients on the diet in pregnancy and have found a dramatic reduction in nausea. We recommend snacking every two hours in pregnancy.

The other "traditional" issue in pregnancy are cravings. These also likely stem from hypoglycemia. I have had many husbands tell us later that their wives, in contrast to friends etc, were calm and not moody or anxious during their pregnancies. Hypoglycemia probably is a serious issue for the fetus as well and may be the "signal" that turns on the insulin-resistant gene. Many theorists feel this might be an activated gene during the pregnancy.


WD: Do you use any unique approaches to the low-carbohydrate approach, e.g., inclusion of dairy, meal frequency, "induction" strategies (i.e., induction to the diet, not of labor!), etc.?

MF: Yes. As I'm sure everyone who works in the VLCD world does, we also have some tricks to make this work better. My biggest push, although hard to get patients to agree, is to see a counselor along with our follow-up in order to deal with "addictive behaviors" and "stress eating" that so many of our patients relate to us. Good stress management and cognitive behavioral therapy go a long way in helping this become a permanent change.

We also really push frequent calorie intake or "snacking." I think again that hypoglycemia produces an inborn drive to "cure" or "fix" starvation and leads to dramatic overeating. We have a short list of snacks that we recommend. The concept of hunger is offered as a failure of the program. We aim to eliminate hunger, as it represents hypoglycemia. The analogy I use is, if you drove your car until you ran out of gas before you ever sought to find gas, your life would be miserable. So it is the same with your metabolic engine: If you let it run out, the measures your system takes to fix it are very detrimental to life and certainly to nutritional health.

Our other big push is fat. People can wrap themselves around protein and vegetables, but they totally miss the high-fat (animal fat) part of the conversation. We have to really push that aspect. In regards to dairy, we allow for non-processed cheeses and minimal milk. An alternative is to mix about 4 oz whole milk with 4 oz of heavy whipping and 4 oz of water to create a "milk" with less sugar. Similarly, shakes and smoothies can be made with heavy whipping cream with pure whey protein powder added to create a liquid meal for those who "don't have time" to cook.


WD: Thanks, Dr. Fox. We look forward to hearing more about your approach in future.

Track Your Plaque reduces healthcare costs 35%

Allow me to wear my Track Your Plaque hat for this post.

Mr. Richard Rawle is CEO of Utah company, Tosh, Inc. Mr. Rawle has been an avid follower of the Track Your Plaque program and has introduced the program to company employees. Here's what he has to say about the experience:

“Our company has been utilizing the principles of TYP [Track Your Plaque] for over a year and has experienced great results that have positively impacted the lives of our employees and our health care costs.

Since we began our wellness program, we have presented the TYP diet and lifestyle guidelines to all of our employees and their families. Although the overwhelming majority of our employees do not have cardiovascular issues, the preventative nature of TYP is too important not to be utilized. The TYP principles along with our increased focus on healthy living have already changed our group’s blood chemistry. HDL levels in particular have increased significantly and resulted in a large percentage of our employees having HDL levels of 60 or higher. Vitamin D levels have substantially increased and LDL levels have significantly decreased in the majority of our employees. Subsequently, in the 12 months just ended, our health care costs are some 35% less than other groups of comparable size and age.

I believe the TYP program has been an integral part of the success of our company's vast improvement in employee health/wellness, resulting in significant health care cost reductions."

Richard Rawle
CEO Tosh Inc.


Track Your Plaque saves lives. Track Your Plaque also saves money . . . lots of it. Despite the upfront costs of some additional blood testing and a heart scan, the dramatic reduction in need for medications, reduced heart attack, diabetes, and many other chronic conditions add up to a huge cost savings, much as Tosh, Inc. employees have enjoyed.

The Federal government has been looking towards large hospital systems to lead the way in healthcare delivery, systems that employ their physicians and possess economies of scale. But I say the answer to reducing healthcare costs will NEVER be found in hospital systems. Healthcare cost savings will be realized by delivering truly effective health solutions directly to people themselves, much as we do in Track Your Plaque.

In search of wheat

Many people ask: "How can wheat be bad if it's in the Bible?"

Wheat is indeed mentioned many times in the Bible, sometimes literally as bread, sometimes metaphorically for times of plenty or freedom from starvation. Moses declared the Promised Land "a land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey" (Deuteronomy 8:8).

Wheat is a fixture of religious ceremony: sacramental bread in the Eucharist of the Christian church, the host of the Holy Communion in the Catholic church, matzoh for Jewish Passover, barbari and sangak are often part of Muslim ritual. Wheat products have played such roles for millenia.

So how can wheat be bad?

What we call wheat today is quite different from the wheat of Biblical times. Emmer and einkorn wheat were the original grains harvested from wild growths, then cultivated. Triticum aestivum, the natural hybrid of emmer and goatgrass, also entered the picture, gradually replacing emmer and einkorn.

The 25,000+ wheat strains now populating the farmlands of the world are considerably different from the bread wheat of Egyptians, different in gluten content, different in gluten structure, different in dozens of other non-gluten proteins, different in carbohydrate content. Modern wheat has been hybridized, introgressed, and back-bred to increase yield, make a shorter stalk in order to hold up to greater seed yield, along with many other characteristics. Much of the genetic work to create modern wheat strains are well-intended to feed the world, as well as to provide patent-protected seeds for agribusiness.

What is not clear to me is whether original emmer, einkorn, and Triticum aestivum share the adverse health effects of modern wheat.

Make no mistake about it: Modern wheat underlies an incredible range of modern illnesses. But do these primitive wheats, especially the granddaddy of them all, einkorn, also share these effects or is it a safe alternative--if you can get it?

I've ordered 2 lb of einkorn grain, unground, from Massachusetts organic farmer, Eli Rogosa, who obtained einkorn seed from the Golan Heights in the Middle East. We will be hand-grinding the wheat and making einkorn bread. We will eat it and see what happens.

Super-carbohydrate

Wheat starches are composed of polymers (repeating chains) of the sugar, glucose. 75% of wheat carbohydrate is the chain of branching glucose units, amylopectin, and 25% is the linear chain of glucose units, amylose.

Both amylopectin and amylose are digested by the salivary and stomach enzyme, amylase, in the human gastrointestinal tract. Amylopectin is more efficiently digested to glucose, while amylose is less efficiently digested, some of it making its way to the colon undigested.

Amylopectin is therefore the “complex carbohydrate” in wheat that is most closely linked to its blood sugar-increasing effect. But not all amylopectin is created equal. The structure of amylopectin varies depending on its source, differing in its branching structure and thereby efficiency of amylase accessibility.

Legumes like kidney beans contain amylopectin C, the least digestible—hence the gas characteristic of beans, since undigested amylopectin fragments make their way to the colon, whereupon colonic bacteria feast on the undigested starches and generate gas, making the sugars unavailable for you to absorb.

Amylopectin B is the form found in bananas and potatoes and, while more digestible than bean amylopectin C, still resists digestion to some degree.

The most digestible is amylopectin A, the form found in wheat. Because it is the most readily digested by amylase, it is the form that most enthusiastically increases blood sugar. This explains why, gram for gram, wheat increases blood sugar to a much greater degree than, say, chickpeas.

The amylopectin A of wheat products, “complex” or no, might be regarded as a super-carbohydrate, a form of highly digestible carbohydrate that is more efficiently converted to blood sugar than nearly all other carbohydrate foods.

More Vitamin D and HDL

I’m seeing more and more of it and I am convinced that there is a relationship: significant boosts in HDL cholesterol from vitamin D supplementation.

To my knowledge this remains an undescribed and uncharacterized phenomenon. There have been several observers over the last two decades who have noticed that total cholesterol shows a seasonal fluctuation: cholesterol goes up in fall and winter, down in spring and summer; year in, year out. This phenomenon was unexplained but makes perfect sense if you factor in vitamin D fluctuations from sun exposure.

I have come across no other substantiating evidence about fluctuations of HDL. But I am convinced that I am seeing it. Replace vitamin D to a blood level of 50 ng/ml, and HDL goes up if it is low to begin with. If HDL is high to begin with, say, 63 mg/dl, it doesn’t seem to change.

But, say, starting HDL is 36 mg/dl. You take niacin, 1000 mg; reduce high-glycemic index foods like breakfast cereals, breads, cookies, bagels, and other processed carbohydrate foods; exercise four days a week; add a glass of red wine a day; even add 2 oz of dark chocolate. You shed 15 lbs towards your ideal weight. After 6 months, HDL: 46 mg/dl. Better but hardly great.

Add vitamin D at a dose of, say, 4000-6000 units per day (oil-based gelcap, of course!), and re-check HDL two or three months later: 65 mg/dl.

I’ve seen it happen over and over. It doens't occur in everybody but occurs with such frequency that it’s hard to ignore or attribute to something else. What I’m not clear about is whether this effect only occurs in the presence of the other strategies we use to raise HDL, a “facilitating” effect, or whether this is an independent benefit of HDL that would occur regardless of whatever else you do. Time will help clarify.

We are tracking our experience to see if it holds up, how, and to what degree on a more formal basis. Until then, a rising HDL is yet another reason—-among many!-—to be absolutely certain your 25-OH-vitamin D3 level is at 50 ng/ml or greater.

How high is an ideal vitamin D blood level? If 50 ng is good, is 60 or 70 ng even better? Probably not, but there are no data. We have to wait and see. Unlike a drug that enjoys plentiful “dose-response” data, there are no such observations for vitamin D into this higher, though still “physiologic,” range.

Thin ice

How long can an industry built on ignorance and deception continue its practices in the new Information Age?

I don’t think it can for long. I talk to hospital administrators who believe that their source of competition is the hospital across town, battling for the same patients. I speak to my colleagues, the cardiologists, who believe that the current model is sustainable—take every willing body to the catheterization laboratory or operating room for heart procedures, the revenue-generating engine of income and expanding heart programs.

I speak to primary care physicians, who are dumbfounded and perplexed and have no idea which way things are going. They are trapped in a peculiar position: most have signed contracts and are employees of the hospital. They are legally bound to support the cardiologists who take anybody possible to the catheterization laboratory or direct patients to other profit-making procedures.

Much of this system depends on the willingness of the participant, meaning you and the health care seeking public. What happens when the truth comes out and disseminates widely through the thinking populace? What happens to hospitals and physicians and the vast structures they’ve built when the bottom drops out for 50% of their “market?

The proverbial cow manure will hit the fan. Upheavals in the medical industry will rival the changes that the automobile or telephone brought early in the last century. Cardiologists, immense hospital heart programs, and the vast economic infrastructure they spawned will go the way of stage coach manufacturers and the telegraph.

What form will the broad exposure of detailed information in health take? I’m not sure, but it will certainly come. The collaborative efforts that created the Linux operating system and have challenged the monopoly of Microsoft Windows, or the emergence of the extraordinary Wikipedia as a repository of human knowledge that dwarfs the venerated Encylopedia Brittanica, will eventually overtake the American medical system, the heart disease industry in particular.

If you base your future on the welfare of your local hospital or the manufacturers of stents, operating room equipment for heart bypass, or similar industries, watch out. The ice is thin. And as the spring warms the air around you, it gets thinner.

The Track Your Plaque program is our first step in broadcasting the message of self-empowerment in heart health care and an attempt to wrestle control away from the profit-seeking forces that dominate. As we grow, we not only hope to broadcast the message more widely, but expand the message to other areas of health. I predict that the collaborative, let’s-all-pitch-in-and-help spirit of the Information Age, “version 2.0,” will spark the change.

Vitamin D and cancer

Although this is a Blog about heart scans and heart disease, I came across a helpful video from Dr. Joseph Mercola about vitamin D and cancer that's worth viewing. Though I do not agree with many of Dr. Mercola's on-the-edge views, he does come up with some good thoughts and, in this instance, a useful educational tool about vitamin D.

You can view his video (which he claims crashed his server, due to the excessive demand for downloads) by cutting and pasting the address into your URL bar (above):

http://v.mercola.com/blogs/public_blog/How-to-Reduce-Your-Risk-of-Cancer-By-50--8790.aspx

Also, for my many patients who I've directed to look in my Blog for Dr. Reinhold Vieth's webcast presentation on vitamin D, here's the address:

http://tinyurl.com/f93vl

Perhaps I carry on too much about vitamin D. But I've come to respect this "nutrient" as among the most powerful strategies I've seen for dramatically improving control over coronary plaque growth as well as other aspects of health, as Drs. Mercola and Vieth eloquently detail.

Lipoprotein(a), menopause, and andropause

Lipoprotein(a) is a curious lipoprotein. Not only is it a genetic pattern with numerous variations, it is also one that shows a predictable age-dependent rise.

Women in particular are prone to this effect, men to a lesser degree. As we age, many hormones recede, particularly growth hormone, testosterone, the estrogens (estradiol, estriol, estrone), progesterone, and DHEA, among others. This is not a disease but the process of senescence, or aging.

When we're young, estrogens, testosterone, and DHEA all exert suppressive effects to keep lipoprotein(a), Lp(a), at bay. But as a woman proceeds through her pre-menopausal and menopausal years, and as a male passes through his fourth decade, there is an accelerated decline of these hormones. As a result, Lp(a) crawls out of its cave and starts to sniff around.

Typically, a woman might have a Lp(a) of 75 nmol/l (approximately 30 mg/dl) at age 38. Ten years later, at age 48, her Lp(a) might be 125 nmol/l (app. 50 mg/dl), all due to the decline of estrogens and DHEA. A parallel situation develops in males due to the drop in testosterone. For this reason, it may be necessary to re-check Lp(a) once after the fourth decade of life if you've had a level checked in your younger years.

This opens up some interesting therapeutic possibilities. If receding hormones are responsible for unleashing Lp(a), hormones can be replenished to reduce it. In males, this is relatively straightforward: supplement human testosterone and Lp(a) drops about 25%.

In women, however, it's a bit murkier, thanks to the negative experince reported using horse estrogens (AKA Premarin) in the HERS Trial and Women's Health Initiative. You'll recall that women who take horse estrogens and progestins (synthetic progesterone) do not experience less heart attack and develop a slightly increased risk of endometrial and breast cancer. There was, however, a poorly-publicized sub-study that showed that women with Lp(a) experience up to 50% fewer heart attacks on the horse/synthetic combination.

Wouldn't it be nice to have a large trial examining the safety/advisability of human estrogens and progesterone? To my knowledge, no such confident study in a significant number of women exists, since there's so little money to be made with human hormonal preparations.

For these reasons, we use lots of DHEA, generally at doses of 25 to 50 mg per day. It makes most people feel good, boosts energy modestly, increases muscle, and reduces Lp(a) up to 18% in women, a lesser quantity in men.

"I have never seen regression"

At a presentation at the American College of Cardiology meetings in New Orleans yesterday (March 27, 2007), Dr. Arthur Agatston declared "I have been doing CT for many years, and I have never seen regression."

Whooooaaaa. Wait a minute here. I have great respect for the work Dr. Agatston has done over the years. He is, after the originator of the scoring algorithm that allows us to score CT heart scans (though a more accurate measure, the volumetric score, is the one we often use behind closed doors because of modestly increased accuracy and reproducibility). His diet program, the South Beach Diet, has achieved enormous success and is indeed an effective approach for both weight loss and correction of many weight-related causes of heart disease.

But he has never seen regression? Why would this be when we see it all the time? When we see heart scan scores drop 30%, it's hard to believe that with some savvy he has never seen regression (drop in score).

I can only attribute the difference to the more intensive endpoints we advocate (e.g., 60-60-60 for lipid values); the incorporation of adjuncts like fish oil, vitamin D, l-arginine; attention to non-cholesterol issues and intensified treatments for each. I doubt that the populations we see differ substantially.

As much as I admire Dr. Agatston's accomplishments, I believe that he is behind the times on this issue. No regression is so starkly different from the Track Your Plaque experience. I believe that relying only on statin drugs and diet will slow but will not stop plaque growth. It will also rarely, if ever, drop your score.

Attention to detail and a little insight into better preventive strategies really pays off. While not everyone in the Track Your Plaque experience will drop their score, a substantial number do. Many more slow plaque growth dramatically. And, as time goes on, our track record gets stronger and stronger.

COURAGE to do better

The results of the long-awaited COURAGE Trial were announced today at the American College of Cardiology meetings in New Orleans.

In this trial, 2200 participants with stable coronary disease (i.e., not unstable, in which heart attack or death is imminent) were randomly assigned ("randomized") to either angioplassty/stent or "maximal medical therapy." Medical therapy means such things as aspirin, beta blocker drugs, and statin cholesterol drugs. There was virtually no difference between the groups in rate of heart attack and death from heart disease over a period of up to 7 years.

These results have caused a stir in the media and my colleagues, trying to sort out of the implications. However, I think there's one observation in particular worth making for those of us who tend to scoff at the conventional approach to coronary disease. That is, 1 of 5 people had a heart attack or died from heart disease in both groups. That's a lot. Even more ended up with a procedure (angioplasty, stent, or bypass). In other words, the "maximal medical therapy" instituted in participants was hardly a success. Though angioplasty and stenting failed to prove superiority, both really stunk. Both permitted a lot of catastrophes to occur.

"Maximal medical therapy," in other words, is a laughable concept. It doesn't include raising HDL, suppressing small LDL, reducing Lipoprotein(a), addressing inflammatory issues. It does not include omega-3 fatty acids from fish oil, nor does it address the severe degrees of vitamin D deficiency that are proving, in the Track Your Plaque experience, to be among the most potent causes of atherosclerotic plaque known. It includes a sad attempt at diet, as advocated by the American Heart Association, a diet that, in my view, causes heart disease and is distorted by the powerful political and financial influence of food manufacturers.

If the trial were to be done again, I'd like to see the "maximal medical therapy" arm be represented by a more effective program like the Track Your Plaque approach.

Value of a zero heart scan score

Margaret is 73. She's a very good 73. She loves children and works full-time in a daycare. She manages her own household, goes to dinner at least once each week with one or more of her adult children. She is slender and has never been in the hospital--until she developed an abnormal heart rhythm called atrial fibrillation.

Most people who develop atrial fibrillation do so with no immediate identifiable cause. However, Margaret has been a widow since her husband died 15 years ago of a heart attack. She was therefore especially frightened of any heart issues in her own health. Her doctor also raised the question of whether atrial fibrillation might represent the first hint of future heart attack.

So we advised a CT heart scan. Score: zero, or no detectable plaque whatsoever. This put Margaret's risk for heart attack as close to zero as humanly possible. (Nobody is truly at zero risk for heart attack for a number of reasons. One reason is that people do irrational things like take cocaine or amphetamines, or they take too much decongestant medication, all of which can trigger heart attack.)

The heart scan settled it. Margaret has the sort of atrial fibrillation which likely simply develops as a result of "wear and tear" on the heart's electrical impulse conducting system and it has nothing to do with coronary heart disease or heart attack.

As that MasterCard commercial goes: Cost of a heart scan: About $200. Peace of mind: priceless.

You're at the cutting edge

If you're a participant in the Track Your Plaque program for atherosclerotic plaque regression, you are at the cutting edge of health.

Few physicians give this issue any thought. Chances are, for instance, that if you were to bring up the subject of reversal of heart disease to your primary care physician, you'd get a dismissive "it's not possible," or " Yeah, it's possible but it's rare."

Ask a cardiologist and you might make a little more progress. He/she might tell you that Lipitor 80 mg per day or Crestor 40 mg per day might achieve a halt in plaque growth or a modest reduction of up to 5-6%. If they've tried this strategy, they would likely also tell you that hardly anybody can tolerate these doses for long due to muscle aches. I'd estimate that 1 of 10 of my colleagues would even be aware of these studies.

Both groups are, however, reasonably adept at diagnosing chest pain, an everyday occurrence in hospitals and offices. Chest pain, for them, is a whole lot more interesting. It holds the promise of acute catastrophe and all its excitement. It also holds the key to lots of hospital revenues. Did you know that 80% of all internal medicine physicians are now employees of hospitals? They're also commonly paid on an incentive basis. More revenues, more money.

Ask Drs. Dean Ornish or Caldwell Esselstyn about reversal of heart disease and they will tell you that a very low-fat diet (<10% of calories)can do it. That's true if you use a flawed test of coronary disease like heart catheterization (angiograms) or nuclear stress tests (Ornish calls them "SPECT"). It would be like judging the health of the plumbing in your house by the volume of water flowing out the spigot. It flows even when the pipes are loaded with rust.

In the Track Your Plaque experience, extreme low-fat diets (i.e., high wheat, corn, and rice diets) grotesquely exagerrate the small LDL particle size pattern, among the most potent triggers for coronary plaque growth. This approach also makes your abdomen get fatter and fatter and inches you closer to diabetes. Triglycerides go up, inflammation increases.

If you were able to measure the rust in the pipes, that would be a superior test. You can measure the "rust" in your "pipes," the atherosclerotic plaque in your coronary arteries, using two methods: CT heart scans or intracoronary ultrasound. Take your pick. I'd choose a heart scan. It's safe, accurate, inexpensive. I've performed many intracoronary ultrasounds for people in the midst of heart attacks or some other reason to go to the catheterization laboratory. But for well people, without symptoms, who are interested in identifying and tracking plaque? That's the place for heart scans.

In our program, 18-30% reductions in heart scan scores are common.

A stent--just in case

Burt came to me last week. He'd received a stent a few months earlier. He'd been feeling fine except for some fatigue. A nuclear stress test proved equivocal, with the question of an abnormal area of blood flow in the bottom (inferior wall) of the heart.

"The doctor said I had a 50% blockage. Even though it wasn't really severe, he said I'd be better off with a stent, just in case."

Just in case what? What justification could there be for implanting a stent "just in case"? (The artery that was stented did not correspond to the area of questionable poor blood flow on the nuclear stress test.)

Just in case of heart attack? If that's the case, what about the several 20 and 30% blockages Burt showed in other arteries? The cardiologist was apparently trying to prevent the plaque "rupture" that results in heart attack by covering it with a stent. Why stent just one when there were at least 7 other plaques with potential for rupture?

That's the problem. And that's why stents do not prevent heart attack (unless the stent is implanted in the midst of heart attack, when the rupturing plaque declares itself.) Of course, when no plaque is in the midst of rupturing, as with Burt, there's no way to predict which plaque will do so in future. Since only one plaque was stented, there is a 7 out of 8 chance (87.5%) that the wrong plaque was chosen. And that's assuming that there aren't plaques not detected by catheterization angiogram; there commonly are. The odds that the right plaque was chosen would be even lower.

In other words, stenting one blockage that is slightly more "severely blocked" in the hopes of preventing heart attack is folly. If it's not resulting in symptoms and blood flow is not clearly reduced, a stent can not be used to prevent plaque rupture. A stent is not a device to be used prophylactically. It is especially silly when an approach like ours is followed, since plague progession is a stoppable process.

Note: This issue is distinct from the one in which symptoms and/or an abnormal stress test show clearly reduced blood flow and flow is restored by implantation of a stent. While some controversies exist here, as well, a stent implanted under these circumstances may indeed provide some benefit.

How will you know your score dropped?

This issue came up twice this week.

Bill is a busy accountant. Two years ago, just after the tumult of the 2005 tax season was over, he got a CT heart scan. His score: 398. At age 53, this was a significant score. His internist did the usual: prescribed a statin (Zocor), told him to cut the fat in his diet, and be sure to exercise. (Yawn.)

Since then, Bill quit preparing tax returns and migrated to a less harried job in corporate accounting. It took two years since his heart scan for Bill to start thinking that perhaps his doctor's advice wasn't enough. If it was, he realized, everyone on a statin drug who made these minimal lifestyle changes would be cured of heart attack risk. Clearly not the case.

So Bill enrolled in the Track Your Plaque program. Our first step: Get another heart scan.

Bill was surprised. "Why another scan? I already had one!"

I explained to Bill that atherosclerotic plaque is like money: it grows in percentages, just like money in a bank account or in a mutual fund. If, for instance, you deposit $500 in a mutual fund and it yields 5% return, then after one year you will have $550. One year later, you will have 5% x $550, or $605. Another year: $665. In other words, growth is not 10% of the original amount you deposited. Growth is compounded, year over year. That's why money, when compounded, can grow so quickly.

Atherosclerotic plaque and your CT heart scan score do the same thing: they grow by a percentage of the current plaque quantity. In fact, we use the compound interest equation to calculate the annualized rate of plaque growth. But plaque grows at the extraordinary rate of 30% per year, on average. Imagine that was the rate of return on your money. You'd be the richest man or woman on earth.

Back to Bill. Now Bill, in his defense, was on a statin drug and did make modest efforts towards a (mis-guided) low-fat diet and walking four days per week. If, on a second CT heart scan, his score was:

398--No change. That's a success, since the expected rate of increase of 30% has been stopped. However, on his current program, this is highly unlikely. (I've seen it happen just once ever out of about 2000 people.)

250--Pop the cork on your champagne, because Bill needs to celebrate. He has substantially reversed his plaque. Highly unlikely on the current effort.

525 --The score is higher by 30%, so it has slowed, but it surely hasn't stopped. This is the most typical result on the sort of program Bill is following.

The message: Don't delay after your first heart scan score. It plaque grows like money with a huge return, there's no time like the present to take the steps to regain control.

Fish oil makes you happy: Psychological distress and omega-3 index

For another perspective on omega-3 blood levels, here's an interesting study in northern Quebec Inuits.

Traditionally, Inuits consumed large quantities of omega-3-rich seal, fish, caribou, and whale, even eating the fat. However, like the rest of the world, modern Inuits have increased consumption of store-bought foods, largely processed carbohydrates. Along with this trend has emerged more heart disease, diabetes, and depression.

A group from Laval University and University of Guelph, both in Canada, examined the relationship of plasma EPA + DHA levels and measures of psychological distress. This group had previously shown that Inuits older than 50 years had twice the plasma omega-3 levels (11.5%) compared to those younger than 50 years (6.5%), reflecting the shift away from the traditional diet.

Psychological distress was measured with The Psychological Distress Index Santé-Québec Survey (PDISQS-14): the higher the score, the greater the psychological distress. (In the graphs, tertile 1 is least distressed; tertile 5 is most distressed. Sorry about the small chart graphic--click on the graphic to make it bigger.)


From Lucas M et al 2009 (http://www.nutrasource.ca/NDI/Assets/Articles/Plasma%20omega-3%20and%20psychological%20distress%20among%20Nunavik%20Inuit.pdf)

"Our main finding was that women in the second and third tertiles of EPA+DHA concentrations in plasma PLs [phospholipids] had a 3 times lower risk of having a high-level PD [psychological distress] score than women in the lowest tertile."

While the relationship is stronger for women, you can see that, the higher the EPA + DHA plasma level, the lower the likelihood of psychological distress. Interestingly, the tertile with the greatest distress and lowest EPA + DHA levels had a plasma level of 7.0-7.5%--far higher than average Americans.

(Plasma levels of EPA + DHA were used in this study, which tend to reflect more recent omega-3 intake than the more stable and slower-to-change RBC Omega-3 Index that we use. Plasma levels also tend to run about 10-20% lower than RBC levels.)

Of course, there's more to psychological distress than omega-3 blood levels. After all, eating fish or taking fish oil capsules won't make money worries go away or heal an unhappy marriage. But it is one variable that can be easily and safely remedied.

Hospitals are a hell of a place to get sick

I answered a page from a hospital nurse recently one evening while having dinner with the family.

RN: "This is Lonnie. I'm a nurse at _____ Hospital. I've got one of your patients here, Mrs. Carole Simpson. She's here for a knee replacement with Dr. Johnson. She says she's taking 12,000 units of vitamin D every day. That can't be right! So I'm calling to verify."

WD: "That's right. We gauge patients' vitamin D needs by blood levels of vitamin D. Carole has had perfect levels of vitamin D on that dose."

RN: "The pharmacist says he can replace it with a 50,000 unit tablet."

WD: "Well, go ahead while Carole's in the hospital. I'll just put her back on the real stuff when she leaves."

RN: "But the pharmacist says this is better and she won't have to take so many capsules. She takes six 2,000 unit capsules a day."

WD: "The 50,000 units you and the pharmacist are talking about is vitamin D2, or ergocalciferol, a non-human form. Carole is taking vitamin D3, or cholecalciferol, the human form. The last time I checked, Carole was human."

RN: (Long pause.) Can we just give her the 50,000 unit tablet?

WD: "Yes, you can. But you actually don't need to. In fact, it probably won't hurt anything to just hold the vitamin D altogether for the 3 days she's in the hospital, since the half-life of vitamin D is about 8 weeks. Her blood level will barely change by just holding it for 3 days, then resuming when she's discharged."

RN: (Another long pause.) Uh, okay. Can we just give her the 50,000 units?"

WD: "Yes, you can. No harm will be done. It's simply a less effective form. To be honest, once Carole leaves the hospital, I will just put her back on the vitamin D that she was taking."

RN: "Dr. Johnson was worried that it might make her bleed during surgery. Shouldn't we just stop it?"

WD: "No. Vitamin D has no effect on blood coagulation. So there's no concern about perioperative bleeding."

RN: "The pharmacist said the 50,000 unit tablet was better, also, because it's the prescription form, not an over-the-counter form."

WD: "I can only tell you that Carole has had perfect blood levels on the over-the-counter preparation she was taking. It works just fine."

RN: "Okay. I guess we''ll just give her the 50,000 unit tablet."


From the alarm it raises trying to administer nutritional supplements in a hospital, you'd think that Osama Bin Laden had been spotted on the premises.

I laugh about this every time it happens: A patient gets hospitalized for whatever reason and the hospital staff see the supplement list with vitamin D, fish oil at high doses, iodine, etc. and they panic. They tell the patient about bleeding, cancer, and death, issue stern warnings about how unreliable and dangerous nutritional supplements can be.

My view is the exact opposite: Nutritional supplements are a wonderful, incredibly varied, and effective array of substances that, when used properly, can provide all manner of benefits. While there are selected instances in which nutritional supplements do, indeed, have interactions with treatments provided in hospitals (e.g., Valerian root and general anesthesia), the vast majority of supplements have none.

Does fish oil cause blood thinning?

Omega-3 fatty acids from fish oil have the capacity to "thin the blood." In reality, omega-3s exert a mild platelet-blocking effect (platelet activation and "clumping" are part of clot formation), while also inhibiting arachidonic acid formation and thromboxane.

But can fish oil cause excessive bleeding?

This question comes up frequently in the office, particularly when my colleagues see the doses of fish oil we use for cardiovascular protection. "Why so much fish oil? That's too much blood thinning!"

The most recent addition to the conversation comes from a Philadelphia experience reported in the American Journal of Cardiology:

Comparison of bleeding complications with omega-3 fatty acids + aspirin + clopidogrel--versus--aspirin + clopidogrel in patients with cardiovascular disease.(Watson et al; Am J Cardiol 2009 Oct 15;104(8):1052-4).

All 364 subjects in the study took aspirin and Plavix (a platelet-inhibiting drug), mostly for coronary disease. Mean dose aspirin = 161 mg/day; mean dose Plavix = 75 mg/day. 182 of the subjects were also taking fish oil, mean dose 3000 mg with unspecified omega-3 content.

During nearly 3 years of observation, there was no excess of bleeding events in the group taking fish oil. (In fact, the group not taking fish oil had more bleeding events, though the difference fell short of achieving statistical significance.) Thus, 3000 mg per day of fish oil appeared to exert no observable increase in risk for bleeding. This is consistent with several other studies, including that including Coumadin (warfarin), with no increased bleeding risk when fish oil is added.

Rather than causing blood thinning, I prefer to think that omega-3 fatty acids from fish oil restore protection from abnormal clotting. Taking omega-3 fatty acids from fish oil simply restores a normal level of omega-3 fatty acids in the blood sufficient to strike a healthy balance between blood "thinning" and healthy blood clotting.

Heart Scan Blog readers take impressive doses of omega-3s

Here are the results from the latest Heart Scan Blog poll:

What is your dose of omega-3 fatty acids, EPA + DHA, from fish oil? (Add up the total content of EPA + DHA per capsules; multiply times number of capsules.)

The 479 respondents answered:

Less than 1000 mg per day
65 (13%)

1000-1999 mg per day
145 (30%)

2000-2999 mg per day
98 (20%)

3000-3999 mg per day
79 (16%)

4000-4999 mg per day
33 (6%)

5000-5999 mg per day
14 (2%)

6000 mg per day or more
45 (9%)


The poll did not discriminate between who has heart disease, who does not; who is taking omega-3 fatty acids for high triglycerides or for reduction of lipoprotein(a) (which requires high doses), or other indications. So variation is to be expected.

We can say that nearly all respondents are likely receiving sufficient omega-3s to impact cardiovascular risk, since the benefits begin just by consuming fish twice per month. I am especially impressed at the proportion of respondents (53%) who take at least 2000 mg per day of EPA + DHA. It's clear that people are really embracing the notion that omega-3 fatty acids pack a real wallop of health benefits.

Because different people in different situations and lipid/lipoprotein patterns have different omega-3 needs, there is really no "right" or "wrong" dose of omega-3 fatty acids.

However, there are several factors that enter into knowing your ideal omega-3 intake:

--Higher triglycerides require higher doses
--Lipoprotein(a) can respond to higher doses
--Having coronary or carotid plaque means you desire a "therapeutic" dose of omega-3s, not just a "preventive" dose

Time is a factor, also: The longer you take omega-3s, the higher your blood levels go. You can accelerate the replacement of non-omega-3s with higher doses of omega-3s.

But too much is not good either. Some participants in Track Your Plaque, for instance, have experimented with very high doses of EPA + DHA in the 9000-10,000 per day range and witnessed dramatic increases in LDL.

Much of the uncertainty about dosing will also be cleared up as we get more experience with the Omega-3 RBC Index, i.e, the proportion of fatty acids in red blood cells that are omega-3s. We are currently aiming for an Omega-3 Index of 10%, given the heart attack reductions observed at this level.

How old are you?

George walks into my office. I ask him his age.

"I'm 21 years old," he declares.

Yet I look at George. He's got gray thinning hair, his posture is slumped forward rather than erect, the flesh on his upper arms hangs loosely, he's got wrinkles on his hands and face, brown spots on the back of his hands and arms. He looks more like 70 years old to me. "I don't think you're 21 years old. I think you're 70."

"Prove it," he says.

Okay. What now? Minus any formal identification like a driver's license, how do I prove that George is really 70-something and not 20-something? Not an easy thing, when you think about it. If George were a tree, I'd cut him down and count his rings. Is there such a phenomenon in humans?

This is actually a fascinating area of research, looking for reliable biomarkers of aging.

Among the most quantitative markers of aging is telomere length. Telomeres were once dismissed as nonsense sequences in DNA. However, more recent thought among geneticists is that telomeres shorten with aging and provide the body's cells a timeline of aging. This way, George's cells act like they are 70, not 13, and don't start producing gobs of growth hormone and testosterone in preparation for puberty.

What can slow or stall the shortening of telomere length? There are two I'm aware of:

1) Caloric deprivation--i.e., taking in fewer calories. This was among the theories explored by Dr. Roy Walford during his Biosphere2 experience, based on his work in mice that showed that caloric deprivation nearly doubled lifespan.

2) Vitamin D--Richards et al (2007) found that, the higher the vitamin D, the longer the telomere length. The highest vitamin D levels conferred a 5-year effective difference in telomere length.

So, if I could look inside George's cells and count his telomeres, I could judge with confidence whether he was 21 or 70. Or, he could take vitamin D sufficient to increase blood levels to a healthy range and be more like 65.

No high blood pressure

Primitive cultures that were, until recently, unexposed to the modern world, reveal some important insights into blood pressure.

The Yanomamo of South American, the Xingu Indians of Brazil, rural Kenyans, and the natives of Papua, New Guinea have average blood pressures of 103/63 mmHg. Even more incredibly, while 90% of modern Americans will develop high blood pressure as they age, the members of these primitive cultures do not develop age-related hypertension.

What's the secret? Perhaps the full "secret" of their remarkably low blood pressure has not been fully unraveled, but several observations have emerged:

--They are not exposed to modern processed foods like pretzels, crackers, and breakfast cereals.
--Low-carbohydrate foods. Carbohydrates are largely the product of the food industry, convenience foods bought in stores. No such thing in the jungle.
--Living outdoors, having to forage and hunt, walk to your destination, not drive or wait in line for food.
--Outdoor lives, wearing little more than a few strands of clothing, exposes you to plentiful vitamin D activation from sunlight exposure.
--Consuming wild game, rich in omega-3 fatty acids, enhances endothelial health and reduces blood pressure.
--Wild plants, roots, and berries, as well as wild game, along the coast, are richer in iodine.

The studies examining the habits of the Yanomamo and other primitive cultures focused principally on sodium intake. Indeed, the very low sodium intake of primitive cultures was associated with lower blood pressure--up to 6 mmHg reduction. But there's clearly more to learn than "cut your salt."

Name that food

What common food can:

• Cause destructive intestinal damage that, if unrecognized, can lead to disability and death?
• Increase blood sugar higher and faster than table sugar?
• Trigger an autoimmune inflammatory condition in the thyroid (Hashimoto’s thyroiditis)?
• Create intestinal bloating, cramps, and alternating diarrhea and constipation, often labeled irritable bowel syndrome?
• Trigger schizophrenia in susceptible individuals?
• Cause behavioral outbursts in children with autism?
• Cause various inflammatory diseases such as rheumatoid arthritis, ulcerative colitis, dermatitis herpetiformis, systemic lupus, pancreatic destruction, and increase measures of inflammation like c-reactive protein?
• Cause unexplained anemia, mood swings, fatigue, fibromyalgia, eczema, and osteoporosis?


The food is wheat. Yes, the ubiquitous grain we are urged to eat more and more of by the USDA (8-11 servings per day, according to the USDA food pyramid), American Heart Association, American Dietetic Association, and the American Diabetes Association. Wheat is among the most destructive ingredients in the modern diet, worse than sugar, worse than high-fructose corn syrup, worse than any fat.

What other common food can result in such an extensive list of diseases, even death?

Celiac disease alone, a severe intestinal inflammatory condition from wheat gluten, affects an estimated 3 million Americans (Celiac Disease Foundation). The medical literature is filled with case reports of deaths from this disease, often after many years of struggle with incapacitating intestinal dysfunction and the sufferer's last days plagued by encephalopathy (brain inflammation).

What happens when you remove wheat from the diet?

The majority of people quickly shed 20-30 lbs in the first few weeks, selectively lost from the abdomen (what I call “wheat belly”); blood sugar plummets; triglycerides drop up to several hundred milligrams, HDL increases, LDL drops (yes, wheat elimination is a means of achieving marked reduction in LDL cholesterol, especially the small, heart disease-causing variety); c-reactive protein plummets. In addition to this, intestinal complaints improve or disappear, rashes improve, inflammatory conditions like rheumatoid arthritis improve, diabetes can improve or be cured, and behavioral disorders and mood improve.

Along with the ill-fated low-fat dietary advice of the last 40 years, the advice to eat plenty of "healthy whole grains" is responsible for untold disease and suffering. Yes, if you start with a fast food and junk diet and replace some of the calories with whole grains, you will be better off. (That was the logic--the Nutritional Syllogism--of the studies that established the benefits of whole grains over processed, "white" grains.)

But eliminate wheat grains and health takes a huge leap forward. And, no, there is no such thing as wheat deficiency--B vitamins, insoluble fiber, some protein--can easily be replaced by other foods.

Heart Defects Simplified



For as long as I've known him, echocardiography technologist, Ken Heiden, has had a deep fascination with congenital heart disease. Ken has just written a wonderful book on congenital heart disease called Heart Defects Simplified.

While this is a bit off-topic for the Heart Scan Blog, I know that there is a serious lack of helpful information for people with congenital heart disease and parents of children with congenital heart defects. So I asked Ken to tell us something about his book.



WD: I've reviewed your book and have been thoroughly impressed with the clarity and detail with which you handle a complicated topic. You somehow manage to make it easy to grasp, far more than any other resource I've used in past. Do you feel that your book serves a previously unmet need?

KH: This book serves an unmet need in that it presents the complex subject of congenital heart defects in a simplified manner. Most books on this subject are anywhere from 300-1700 pages in length and tend to be written for doctors. Further, most of these books have very few diagrams, and they rely upon their explanations to describe these defects.

Heart Defects Simplified is 104 pages in length, describes the most common defects, including surgical repairs, in a two-page format with full-color diagrams on the left and complete descriptions on the right of each chapter. The book is particularly written for sonographers, nurses and parents, but it is valuable for anyone interested in this subject. It is particularly useful in clinical situations because it is convenient to lay out at your side with a coil-bound format and durable pages. Further, there are appendixes which include "Surgical Procedures in Alphabetical Order," "Prevalence of Congenital Heart Disease," "Scanning Protocols for Echocardiographers," "Imaging Tips," a glossary and a worksheet for echocardiographers.


WD: I know that many people with loved ones who have congenital heart defects, particularly parents of children with such conditions, are often kept in the dark about the details of the condition. Is your book suitable for the non-technical reader, such as parents?

KH: This book is an excellent resource for parents. It is written in language that is understandable by parents as well as technologists and nurses. The full-color diagrams provide invaluable insight into this very complex world. Most importantly, this book attempts to make the subject of congenital heart defects accessible to anyone who wishes to comprehend this subject.


WD: I understand that people with congenital heart defects and parents are active participants in online discussion groups. Will your book serve as a resource for people who participate in these groups?

KH: This book is not only a resource for sonographers and parents, but the book is accompanied by a blog (HeartDefectsforEveryone.blogspot.com) that attempts to address many of the concerns commonly encountered with congenital heart defects. This blog is a work in progress, but I hope to provide a forum for parents, healthcare personnel, and others to share their questions and concerns about congenital heart disease.

My experience with the omega-3 index

I just got back my own results from the Gene Smart laboratory reporting my omega-3 index and omega-6:omega-3 ratio.

My results:

Omega-3 index: 8.2%

Omega-6:omega-3 index: 3.2 to 1

Not too bad, but not as good as I'd expected. Hmmm.

Although the omega-3 index of 8.2% puts me in the lower risk category for sudden cardiac death, I was hoping for a level of 10% or slightly greater, the level that I believe is more likely to be related to plaque inactivation or reversal. I obtained this level of omega-3 averaging an intake of EPA and DHA of about 2500 mg per day.

I was somewhat disappointed by the omega-6:omega-3 index. Although it's clearly better than the American average range of 20:1, it is short of the ideal of 2:1 or even 1:1. Since I purposely avoid omega-6-rich sources like corn oil, vegetable oils, sunflower or safflower oils, I wonder if I've overdone the nuts. The two ways to improve the omega-6:omega-3 ratio are to 1) decrease omega-6, or 2) increase omega-3. I'm going to do both.

So I thought I was doing pretty well. But there's clearly room for improvement.

Remember: If just reduction of cardiovascular risk is your interest, then a lackadaisical attitude towards these issues might work. But if your interest is elimination of risk and reversal of atherosclerotic plaque, then it pays to go the extra mile. In this case, knowing your omega-3 index and omega-6:omega-3 ratio might tighten up your program.

The Omega-3 Index: The higher, the better?

So you take a few fish oil capsules every day and eat fish once or twice a week. What is the blood and tissue level of omega-3 fatty acids generated by your habits?

A number of variables enter into the equation. For instance, if you take fish oil capsules, what is the concentration of omega-3 fatty acids? How well are they absorbed? After absorption, how effectively are omega-3 fatty acids incorporated into cell membranes?

Even if you take fish oil supplements, it is hard to know just how much you’ve increased blood levels. It is now possible to measure the amount of omega-3 fatty acids in your bloodstream, a value called the omega-3 index. Too little and you might still be at high risk for cardiovascular events.


The Omega-3 index and sudden cardiac death

Two large studies have demonstrated that higher omega-3 blood (the level in red blood cells, or RBCs) levels were associated with reduced likelihood of sudden cardiac death. The risk for sudden cardiac death was 10-fold higher for the lowest omega-3 RBC levels compared to the highest.



Harris WS 2008; adapted from Siscovick DS et al 1995 and Albert CM et al 2002
(The omega-3 Index was derived from whole blood omega-3 levels, which correlate with RBC omega-3 levels, and are thus “estimated.”)



What’s the average omega-3 RBC level for Americans? Most Americans have omega-3 RBC levels in the 2.5-4.0% range, consistent with the tallest bars at the left and associated with greatest risk for sudden cardiac death. People with heart disease can have levels less than 1%. Some authorities propose that this new measure be called the omega-3 index.

Subsequent studies have shown that the omega-3 index has greater power to discriminate who will have a heart attack or die from sudden cardiac death better than any other common laboratory measure of coronary risk, including LDL cholesterol, HDL cholesterol, triglycerides, total cholesterol to HDL ratio, homocysteine, and c-reactive protein.

Just as hemoglobin A1c offers a 3-month look into blood glucose levels, the omega-3 index reflects your long-term omega-3 intake. The quantity of RBC omega-3s also closely parallels the quantity of omega-3s in heart tissues.


What is an ideal omega-3 index?


The above studies relating RBC omega-3 levels and sudden cardiac death suggest that a level of 6.3-7.3% is associated with far fewer fatal events?but events are not eliminated at this level. Is there even greater benefit with levels higher than 6.3-7.3%?

A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks. This suggests that even higher levels are necessary to prevent non-fatal events.

Should we target 10%? 12%? Maybe higher? Any higher and we are toeing the level achieved by the Inuits, the “Eskimoes” of Greenland, northern Canada and Alaska who have been observed to have a low rate of heart disease.


What’s your omega-3 index?

The appreciation of the importance of omega-3 fatty acids marks one of the greatest health revelations of the last 50 years. We can now measure it.

The ability to measure the proportion of omega-3 fatty acids in red blood cells may provide yet another means for all of us to further reduce risk for cardiovascular events.
