The myth of small LDL

28. June 2006 William Davis (1)

Annie's doctor was puzzled.

Despite an HDL cholesterol of 76 mg (spectacular!) and LDL of 82 mg, her CT heart scan showed a score of 135. At age 51, this placed her in the 90th percentile.

Not as bad, perhaps, as her Dad might have had, since he died at age 54 of a heart attack.

So we submitted blood for lipoprotein testing. Surprise! over 90% of all her LDL particles were small. (By NMR, they're called "small". By gel electropheresis, or the Berkeley Lab test, or VAP (Atherotech) technique, they're called "HDL3".)

What gives? Traditional teaching in the lipid world is that if HDL equals or exceeds 40 mg/dl, then small LDL will simply not be present.

Well, as you can see from Annie's experience, this is plain wrong. Yes, there is a graded, population-based effect--the lower your HDL, the greater the likelihood of small LDL. But small LDL is remarkably persistent and prevalent--regardless of your HDL.

We've seen small LDL even with HDLs in the 90's! I call small LDL the "cockroach" of lipids. If you think you have it, you probably do. Getting rid of small LDL requires a specific bug killer. (Track Your Plaque Members: Read Dr. Tara Dall's interview on small LDL.)

Don't let anybody blow off your request for lipoprotein testing just because your HDL is high. That's just not acceptable. Loads can be wrong even with a favorable HDL.

My stress test was normal. I don't need a heart scan!

28. June 2006 William Davis (0)

Katy had undergone a stress test while being seen in an emergency room, where she'd gone one weekend because of a dull pain on the right side of her chest. After her stress test proved normal, she was diagnosed (I believe correctly) with esophageal reflux, or regurgitation of stomach acid up the esophagus. She was prescrbed an acid-suppressing medication with complete relief.

But Katy also had coronary plaque. Three years ago, her CT heart scan score was 157. She'd made efforts to correct the multiple causes, though she still struggled with keeping weight down to gain full control over her small LDL particle pattern.

I felt it was time for a reassessment: another heart scan. After three years, without any preventive efforts, Katy's score would be expected to have reached 345! (That's 30% per year plaque growth.) It's a good idea to get feedback on just how much slowing you've accomplished.

But Katy declared, "But I didn't think another heart scan was necessary. My stress test was normal!"

What Katy was struggling to understand was that even at the time of her first scan, a stress test would have been normal. Plaque can be present with a normal stress test.

Plaque can even show explosive growth all while stress tests remain normal. Just ask former President, Bill Clinton, how much he should have relied on stress tests. (Mr. Clinton underwent annual stress nuclear tests. All were normal and he had no symptoms--all the way up 'til the time he needed urgent bypass surgery!)

Of course, at some point even a crude stress test will reveal abnormal results. But that's years into your disease and a lot closer to needing procedures and experiencing heart attack.

So, yes, Katy would benefit from another heart scan despite her normal stress test.

The message: Don't rely on stress tests to gauge whether or not plaque has grown, stabilized, or reversed. Stress tests can be used to gauge the safety of exercise, blood pressure response, and the potential for abnormal heart rhythms. Stress tests can be used as a method to determine whether blood flow in your coronary arteries is normal through an area with plaque.

But a stress test cannot be used to gauge whether plaque has grown. It's as simple as that. Gauging plaque growth requires a heart scan.

Patient-napping: Yet another reason to stay clear of hospitals!

26. June 2006 William Davis (1)

When I started practicing medicine around 20 years ago, it was common practice to alert a physician when their patient was seen in an emergency room.

If John Smith, for example, went to the emergency room with chest pain, the physician who had an established relationship with the patient--knew their history, had managed their health and illnesses, etc.--was notified, even if the hospital ER had no relationship with the physician. It was not uncommon for the patient to then be transferred to the hospital where their own doctor practiced.

Though cumbersome at times, it preserved the relationship of the patient with their doctor.

Over the past few years, this practice has crumbled. Nowadays, hospitals and their employed physicians (and other unscrupulous physicians acting in the name of profit) "fail" to notify the physician with an established relationship.

Guess what happens? The patient all too often ends up being put through the gamut of testing and procedures.

Why? For hospital profit, of course. If failure to notify a doctor who's had a 10-year long relationship with the patient is "overlooked" or, even more commonly, it's "unsafe" to transfer the patient because the patient is too "unstable" to be transferred, then this patient becomes ripe for picking--heart catheterization, stents, bypass surgery, etc. Ten's, if not hundreds, of thousands of dollars can be reaped by this deception. I call it "patient-napping".

I see this at least several times every month. As hospitals are becoming increasingly competitive, and as they put pressure on their physicians to churn patients for revenues, you're going to see more and more of this.

As always, what is your protection from this expanding influence of hospitals and the doctors too meek to stand up to them? Education and information. Arm yourself with an understanding of what is accomplished in hospitals, when you truly need them, and when you don't.

Take it one step further. At least from a heart disease standpoint--the #1 profit-maker for hospitals--aim to 1)identify your coronary plaque, then 2) seize control over your coronary plaque and reduce your risk for heart attack and heart procedures as much as humanly possible. That's the goal of the Track Your Plaque program.

Don't believe the negative press on fish oil

25. June 2006 William Davis (0)

A British Medical Journal study released in March, 2006 has prompted a media flurry of reports on the worthlessness of fish oil. (Hooper L, Thompson RL, Harrison RA et al. Risks and benefits of omega 3 fats for mortality, cardiovascular disease, and cancer: a systematic review. BMJ March,2006)

Don't believe it for a second.

First of all, the study was a re-analysis of the existing published scientific literature. It was not a new study. It included a wild conglomeration of different clinical observations, as the studies examining fish oil over the years have been extraordinarily heterogeneous--in populations examined, omega-3 supplement (e.g., fish vs. capsule), period of observation, endpoints measured.

The results were skewed by inclusion of a moderate-sized British study by Burr et al in men with angina. In this study, no benefit was demonstrated and, in fact, a negative effect--more heart attack and death--was observed with fish oil. This was not news, since the study was published in 2003. It's results have been a mystery to everyone, since its unexpected negative result for fish oil was so starkly different from virtually every other study that preceded it (suggesting a study flaw or statistical fluke).

Nonetheless, the Burr study served to throw off the overall analysis. It diluted the dramatic and persuasive outcome of the GISSI-Prevenzione Study of 11,000 people in which a 28% reduction in heart attack and 45% reduction in cardiovascular death was observed. Note that the substantial numbers of the GISSI make the study's outcome nearly unassailable.

Another important fact: fish oil is among the most powerful tools available to correct elevated triglycerides. Drops of 50% are common. Recall that triglycerides are a necessary ingredient to create the nasty LDL, as well as VLDL, Intermediate-density lipoprotein, and an undesirable shift from large to ineffective small HDL. Reducing triglycerides is therefore crucial for your plaque control program.

This re-analysis serves to prove nothing. Such analyses can only pose questions for further study in a real study like GISSI: a randomized (random participant assignment), controlled (treatment vs. placebo or other treatment) study.

The weight of evidence remains heavily in favor of fish oil, not only as helpful, but fabulously beneficial, particularly for anyone aiming to reduce coronary plaque.

How important is high blood pressure?

24. June 2006 William Davis (0)

Control of blood pressure is crucial for coronary plaque control and stopping your heart scan score from increasing.

Dr. Mehmet Oz (of Oprah fame and a cardiac transplant surgeon at Columbia University) made graphic point of this on the ABC TV news show, 20/20, last evening on an episode called "Our Bodies: Myths, Lies, and Straight Talk". (See a summary on the ABC News 20/20 website at http://abcnews.go.com/2020/story?id=2109291&page=1)

Although I believe he somewhat overstated the case for hypertension (proclaiming "If you're going to remember one number, if you're going to focus and fixate on one number in your entire health profile, it better be your blood pressure"), he made the point that a blood pressure of 115/75 is what you should have for optimal health.

I couldn't agree more. Unfortunately, the old advice that desirable blood is 140/90 or less is absolutely wrong. At this level, we see flagrant increases in heart scan scores. We also progressive enlargement of the thoracic aorta, the large vessel that leaves the heart and branches to provide the major arteries of the body. Growth of the aorta to an aneurysm is also common at these formerly acceptable blood pressure. (The diameter of your aorta in the chest is an easily obtainable measure on your CT heart scan.)

The blood pressure you need for halting and reversing plaque growth on your heart scan is indeed 115/75 or less. (Not so low, however, that you're lightheaded.) This is the blood pressure that you were meant to have evolutionarily. It's also the blood pressure that helps tremendously in keeping your aorta from enlarging.

Is your doctor in cahoots with the hospital?

21. June 2006 William Davis (0)

I got a call from a doctor about a patient we've seen in past.

"I've got Tricia in the office. She's been having some kind of chest and abdominal pain. I think it's esophageal reflux, but just to be safe I'm sending her to the hospital."

I advised this physician that, given Tricia's low heart scan score, she was unlikely to be having a coronary "event" like heart attack or unstable symptoms. It wasn't impossible, but just highly unlikely.

As the patient was without symptoms at the moment and had driven herself to his office, I offered to perform a stress test immediately. (Though stress tests are of limited usefulness in people without symptoms, they can be useful provocative maneuvers in people with symptoms of uncertain significance.)

The doctor declined. Tricia was, after all, in his office and he was responsible for any decisions despite any objections I voiced. Well, Tricia was directed by her doctor to go to a local hospital, though one with an especially notorious reputation for putting virtually anyone they can get their hands on through as many procedures as possible.

As you might guess, this doctor was closely associated with this hospital. He and his colleagues obtain incentives (or are penalized) if they do not generate revenue-producing procedures for the hospital.

So, guess what? Tricia ended up with several procedures, all of which yielded nothing--except $30,000 in revenues from Tricia's insurance company.

I harp on this deplorable state of affairs because it is utterly, painfully, and shamefully TRUE. Just look at the hospital and you'd better brace yourself for a series of tests that could cost you the equivalent of a nice 3 bedroom home. If they were truly necessary after the failure of preventive and other simple efforts, fine. But, all too often, they are driven by profit motives.

Could I have stopped this somehow from occurring? After all, Tricia was reasonably aware of the way we do things around here. I fear that even this failed to serve Tricia well. But I remain hopeful that, as we build broader awareness of these issues, that more and more people and physicians will stand up and refuse to tolerate the status quo.

Where is the Track Your Plaque program going?

21. June 2006 William Davis (1)

I spend a lot of time worrying about how people can be helped to navigate through this program.

Take, for instance, the man in rural Texas who, while traveling in Dallas, got a heart scan on a whim. His score was 990. When he took the report back to his doctor, he got a smirk--and that's all. When he came to the Track Your Plaque program, he lacked a physician advocate to help him.

Or the woman from Florida who sought opinions from two reputable cardiologists for her heart scan score of 377. Both advised her that she needed a heart catheterization--despite her lack of symptoms, her 5-day-a-week exercise program, and normal stress test. She also lacks a physician advocate who acts on her behalf, helping her achieve success, rather than just churning her for money from hospital procedures.

For people like this and for others, I see the Track Your Plaque program evolving in several directions:

1) An online clinic--You enter and we take your "hand" and lead you step by step through the process, not only at the beginning, but over the months and years. This would help clear up some of the confusion and zigzags that some people experience trying to navigate through the program.

2) Develop physician and non-physician partners--The woman in Florida, for instance, could be referred to a doctor nearby who understands the program and is able to assist her. At present, this is virtually impossible because of the bias towards heart procedures, drugs as the sole treatment for heart disease risk, and the superficial physician-patient relationship. The majority of practicing physicians just don't understand the program despite the fact that it is based on sound clinical and experimental data. But it will in time.

Looking back, we've come a long way. I remember first having patients undergo heart scans 10 years ago. My colleagues laughed or called it "silly". The general public didn't know what they meant.

Now we're talking about how to broadcast the most powerful heart disease prevention program available in the world to a larger audience, but making it easier and more accessible. Mass media like Oprah's two hour-long spots helped, but we need to make the next leap. Not just identifying hidden heart disease to feed the hungry cardiovascular hospital procedure monster, but to educate/inform/empower the public on what to do with the scan once they've had it.

Who cares about triglycerides?

19. June 2006 William Davis (0)

Walter's triglycerides were 231 mg. His LDL cholesterol was "favorable" at 111 mg, HDL likewise at 49 mg.

"Everything looks good," his doctor declared.

"Do you think the triglycerides are okay, too?" Walter asked.

"Well, the guidelines do say that triglycerides should be less than 150, but I believe you're close enough. Anyway, triglycerides don't really cause heart disease."

When I met Walter, I made several comments. First of all, in light of his heart scan score of 713, none of his numbers--HDL, LDL, or triglycerides-- were acceptable. But the triglycerides were glaringly and terribly too high.

Why? What exactly are triglycerides?

Triglycerides are a basic fat particle that, though they do not cause heart disease directly, trigger the formation of an array of abnormal lipoprotein particles in the blood that are among the most potent causes of heart disease known.

These abnormal lipoprotein particles include small LDL, VLDL, and IDL (intermediate-density lipoprotein--a really bad pattern). Excess triglycerides also cause HDL to drop. They also cause a distortion of HDL structure, causing the particles to become abnormally small. Small HDL is also useless HDL, unable to provide the protection that HDL is designed to do.

So Walter's elevated triglycerides are, in reality, a substantial red flag for an entire panel of abnormal particles that contribute to the growth of his coronary plaque.

So, if you get this kind of commentary on your triglycerides, ask for another opinion. (Track Your Plaque Members: Also see Triglycerides: Mother of meddlesome particles at http://www.cureality.com/library/fl_dp002triglycerides.asp.)

Total cholesterol and heart scans

19. June 2006 William Davis (0)

Andy was fearful of heart disease in his life. At age 52, he'd already had four CT heart scans--one each year on or near his birthday.

Yet, when I looked at Andy's scans, his scores had been increasing 20-24% per year. Each and every score was greater by 20% or more over the previous.

So I asked Andy what steps he had taken to stop this relentless progression. "Well, I've always been real health conscious. But ever since my first scan, I really started sticking to a healthy diet, exercising nearly every day, and I take a bunch of supplements."

"What did your doctor advise?" I asked.

"Well, Dr. ---- said that nothing needed to be done, since my total cholesterol was always below 200."

Men's Health magazine's fabulous story about the folly of using total cholesterol to gauge heart disease risk.

Aaaauuuggghhh!! Wrong!

This man was, in fact, at rapidly escalating risk for heart attack. This rate of growth simply can't continue forever without igniting this bomb.

A total cholesterol below 200 is meaningless, as Andy's increasing coronary plaque proved. For instance, you can have a total cholesterol of 165 mg but with an HDL cholesterol of 27 mg. This would constitute very high risk for heart disease despite the low total cholesterol. The low HDL pattern is among the most common reasons for a misleading total cholesterol. Small LDL, high triglycerides, and lipoprotein (a) are other frequent reasons.

Andy, run the other way! Do not heed this doctor's advice! You need a solid answer to the question: Why exactly do I have coronary plaque in the first place?

Then, agree on a treatment program that corrects your specific causes.

Cardiologists out of touch

17. June 2006 William Davis (0)

This weekend, I'm fulfilling some responsiblities I have every so often to some of the local hospitals. It gives me a chance to interact with many of my colleagues who are likewise "on call" for the weekend.

I tried to strike up several conversations with colleagues about how they were managing heart disease prevention. I received blank stares, puzzled looks, indifference. One colleague declared that 80 mg of Lipitor is all you need to know.

These same colleagues are the ones scrambling for the heart attack patients in the emergency room, climbing over one another for consultation in the hospital for patients with chest pain and heart failure. They're consumed with expanding the range of procedures they can perform.

Carotid stenting is hot. So is stenting of the leg arteries. Defibrillators have been a financial bonanza. Opportunities abound on how to add these procedures to a cardiologist's abilities.

But heart disease prevention? How about heart disease reversal?

Frankly, I'm embarassed by my colleagues' lack of interest. Imagine we had a cure for breast cancer--not a palliative therapy that just slows the disease down or prolongs life, but actually cures it once and for all. I would hope that all physicians and oncologists would learn how to accomplish this. What if instead they focused on learning new ways to remove breasts, administer new toxic chemotherapies, etc. but ignored the whole idea of cure?

This is what is happening with coronary plaque reversal. The answer is right in front of them, but the vast majority (99%) of cardiologists choose to ignore it. After all, prevention and reversal simply don't pay the bills.

That means that, in 2006, you simply cannot rely on your cardiologist to counsel you on how to achieve regression or reversal of coronary plaque. How about your internist, family physician, or primary care doctor? Well, they're busy doing pneumovax injections, Pap smears, managing knee and hip arthritis, low back pain, diarrhea, headaches, sinus infections and . . yes, dabbling in heart disease prevention.

And, for the most part, doing a miserable job of it. What you generally get echoes the drug manufacturers pitch: Take a statin drug, cut the fat in your diet.

Until the majority of doctors catch on, you're going to have to rely on sources like the Track Your Plaque program for better information.

In search of wheat: We bake einkorn bread

12. June 2010 William Davis (6)

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?

10. June 2010 William Davis (24)

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

6. June 2010 William Davis (36)

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%

29. May 2010 William Davis (12)

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

26. May 2010 William Davis (43)

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

22. May 2010 William Davis (18)

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.

Emmer, einkorn, and agribusiness

21. May 2010 William Davis (32)

10,000 years ago, Neolithic humans did not obtain wheat products from the bagel shop, grocery store, or Krispy Kreme. They obtained wheat by locating a nearby wild-growing field of wild emmer or einkorn wheat grass, then harvesting it with their stone sickles.

Neolithic humans, such as the Natufians of the Fertile Crescent, carried their freshly-cut wheat home, then ground it by hand using homemade mortar and pestle. As yeast-raised bread was still some 5000 years in the future, emmer and einkorn wheat was not used to bake bread, but was consumed as a porridge in bowls. Einkorn has the simplest genetic code of 14 chromosomes, while emmer has 28 chromosomes.

A third variety of wheat appeared on the scene around 9000 years ago, a natural hybridization between emmer and goat grass, yielding the 42-chromosome Triticum aestivum species. Egyptians learned how to cause wheat to rise around 3000 BC, yielding bread, rather than the unleavened flatbreads of their predecessors.

From the original three basic varieties of wheat available to Neolithic man, over the past 30 years wheat has exploded to over 25,000 varieties. Where did the other 24,997+ strains come from?

In the 1980s, thousands of new wheat strains arose from hybridization experiments, many of them conducted in Mexico. Then, in the late 1980s, genetic engineering quietly got underway in which geneticists inserted or deleted single genes, mostly designed to generate specific characteristics, such as height, yield per acre, drought resistance, but especially resistance to various pesticides and weed killers. The fruits of these efforts were introduced into the market in 1994. Most of the genetically modified foods were thought to be only minor modifications of the unmodified original and thus no safety testing in animals or humans was conducted.

We now have many thousands of wheat strains that are different in important ways from original emmer, einkorn, and Triticum aestivum wheat. Interestingly, it has been suggested that einkorn wheat fails to provoke the same immune response characteristic of celiac disease provoked by modern wheat gluten, suggesting a different amino acid structure in gluten proteins. Another difference: Emmer wheat is up to 40% protein, compared to around 12% protein for modern wheat.

In other words, the wheat of earlier agricultural humans, including the wheat of Biblical times, is NOT the wheat of 2010. Modern wheat is quite a different thing with differing numbers of chromosomes, different genes due to human manipulation, varying gluten protein composition, perhaps other differences.

Somewhere in the shuffle and genetic sleight-of-hand that has occurred over the last 30 years, wheat changed. What might have been the "staff of life" has now become the cause of an incredible array of diseases of "wheat" intolerance.

Near-death experience with nattokinase

16. May 2010 William Davis (22)

This is a true story that I personally witnessed.

A 60-some year old man heard that nattokinase "thinned the blood." So he had been taking it for the past 6 months.

One week before he came to see me, he abruptly became quite breathless. He was unable to walk more than 20 feet or bend over to tie his shoes due to the breathlessness.

He came to see me in the office. I was alarmed by how breathless he was without signs of heart failure or other obvious explanation. I sent him for an immediate CT pulmonary angiogram. Within 30 minutes, we had the diagnosis: a large "saddle" pulmonary embolus, meaning a large blood clot that straddled the right and left main pulmonary arteries. One wrong move and . . . bang! He would have been dead within a couple of minutes, since a large clot can completely occlude the large arteries feeding the lung, essentially corking any blood circuiting through the lungs and back to the left side of the heart. (Causing, incidentally, electromechanical dissociation, in which the heart keeps beating for a few minutes but no blood is being pumped. CPR can keep you alive for a few minutes, then it's over.)

When I advised the patient of the diagnosis (after initiating the REAL anticoagulants), he said, "But I was taking nattokinase!"

Exactly. Blood clots are no laughing matter. They are potentially fatal events. Betting your life on some company's advertisement is nothing short of foolish.

Anyone who reads The Heart Scan Blog knows that I am an avid supporter of nutritional supplements. I even write articles and consult for the supplement industry. But I truly despise hearing unfounded marketing claims that some supplement companies will make in the pursuit of a fast buck.

There is no doubt that we need better, safer methods to deal with dangerous blood clots, whether in the lung, pelvis, or other areas. But, before anyone takes a leap based on the extravagant marketing claims made by a supplement manufacturer, you want to be damn sure there are real data--not marketing claims, REAL data--before you use something like nattokinase in place of a proven therapy.

Don't confuse the very interesting, though unpalatable, natto with nattokinase. Natto contains vitamin K2 and some other interesting compounds, including nattokinase.

Blame the gluten?

14. May 2010 William Davis (17)

Wheat is among the most destructive components of the human diet, a food that is responsible for inflammatory disease, diabetes, heart disease, several forms of intestinal diseases, schizophrenia, bipolar illness, ADHD, behavioral outbursts in autistic children . . . just to name a few.

But why?

Wheat is mostly carbohydrate. That explains its capacity to cause blood sugar to increase after eating, say, a turkey sandwich on whole wheat bread. The rapid release of sugars likely underlies its capacity to create visceral fat, what I call "wheat belly."

But neither the carbohydrate nor the other components, like bran and B vitamins, can explain all the other adverse health phenomena of wheat. So what is it in wheat that, for instance, worsens auditory hallucinations in paranoid schizophrenics? Is it the gluten?

First of all, what is gluten?

Gluten protein is the focus of most wheat research conducted by food manufacturers and food scientists, since it is the component of wheat that confers the unique properties of dough, allowing a pizza maker to roll and toss pizza crust in the air and mold it into shape. The distinctive “doughy” quality of the simple mix of wheat flour and water, unlike cornstarch or rice starch, for instance, properties that food scientists call “viscoelasticity” and “cohesiveness,” are due to the gluten. Wheat is mostly carbohydrate, but the 10-15% protein content is approximately 80% gluten. Wheat without gluten would lose its unique qualities that make it desirable to bakers and pizza makers. Gluten is also the component of wheat most confidently linked to immune diseases like celiac.

The structure of gluten proteins has proven frustratingly elusive to characterize, as it changes over time and varies from strain to strain. But an understanding of gluten structure may be part, perhaps most, of the answer to the question of why wheat provokes negative effects in humans.

The term “gluten” encompasses two primary families of proteins, the gliadins and the glutenens. The gliadins, one of the protein groups that trigger the immune response in celiac disease, has three subtypes: a/ß-gliadins, ?-gliadins, and ?-gliadins. The glutenins are repeating structures, or polymers, of more basic protein structures.

Beyond gluten, the other 20% or so of non-gluten proteins in wheat include albumins, prolamins, and globulins, each of which can also vary from strain to strain. In total, there are over 1000 other proteins that serve functions from protection of the grain from pathogens, to water resistance, to reproductive functions. There are agglutinins, peroxidases, a-amylases, serpins, and acyl CoA oxidases, not to mention five forms of glycerinaldehyde-3-phosphate dehydrogenases. I shouldn’t neglect to mention the globulins, ß-purothionin, puroindolines a and b, tritin, and starch synthases.

As if this protein/enzyme smorgasbord weren’t enough, food processors have also turned to fungal enzymes, such as cellulases, glucoamylases, xylanases, and ß-xylosidases to enhance leavening and texture. Many bakers also add soy flour to enhance mixing and whiteness, which introduces yet another collection of proteins and enzymes.

In short, wheat is not just a simple gluten protein with some starch and bran. It is a complex collection of biological material that varies according to its genetic code.

While wheat is primarily carbohydrate, it is also a mix of gluten protein which can vary in structure from strain to strain, as well as a highly variable mix of non-gluten proteins. Wheat has evolved naturally to only a modest degree, but it has changed dramatically under the influence of agricultural scientists. With human intervention, wheat strains are bred and genetically manipulated to obtain desirable characteristics, such as height (ranging from 18 inches to over 4 feet tall), “clinginess” of the seeds, yield per acre, and baking or viscoelastic properties of the dough. Various chemicals are also administered to fight off potential pathogens, such as fungi, and to activate the expression of protective enzymes within the wheat itself to “inoculate” itself against invading organisms.

From the original two strains of wheat consumed by Neolithic humans in the Fertile Crescent 9000 years ago (Emmer and Einkorn), we now have over 200,000 strains of wheat virtually all of which are the product of genetic manipulations that have modified the protein structure of wheat. The extraordinary complexity of wheat proteins have therefore created a huge black box of uncertainty in pinpointing which protein causes what.

But there's an easy cure for the uncertainty: Don't eat it.

Glycemic gobbledygook

13. May 2010 William Davis (14)

The concept of glycemic index is meant to help determine what foods raise blood sugar a lot vs. what foods raise blood sugar a little. Dr. Jennie Brand-Miller's searchable database can be found here.

I have to admit that glycemic index provided me with a sense of false assurance for some years. It screwed up my health until I came to understand the issues a lot better.

For those of you just starting out in nutritional conversations, glycemic index (GI) represents a comparison of the blood glucose area-under-the-curve (AUC) over 2 hours after consuming 50 grams of the food in question compared to the AUC of glucose or white bread. Volunteers involved in developing these values are healthy people who are generally of normal weight.

Glucose, by definition, has a GI of 100. An equal quantity of sucrose (50% glucose, 50% fructose) has a GI of 60, lower than glucose. An equal quantity of whole wheat bread has a GI of 68-77 (Yes: The GI of whole wheat is higher than sucrose). Non-carbohydrate foods, such as eggs or avocado, have no GI since they do not impact on blood glucose.

Because the GI is also sensitive to how much carbohydrate is contained, the concept of Glycemic Load (GL) was introduced:

GL = (GI x amount of carbohydrate) / 100

GL is therefore the GI that incorporates the glycemic potential of the food of interest. GI does not vary with portion size; GL varies with portion size.

Let's take whole wheat pasta, a food regarded by most people as a healthy choice. Whole wheat pasta has a GI of 55--fairly low--and a GL of 29. A serving of 180 g (approximately 6 oz cooked) provides 50 g carbohydrates.

People who advocate that low-glycemic index foods would say that this is a desirable profile and should therefore replace high-glycemic index foods.

I say WRONG. First of all, most of us are not slender 20-somethings. We will therefore not show the same response as a young, slender person (like the GI volunteers), but will show exagerrated blood sugar responses. So this much low-glyemic index whole wheat pasta will typically yield a blood sugar of 120-200 mg/dl in non-diabetic people, high enough to trigger glycation. Sure, a high-glycemic index food, such as white flour birthday cake with plenty of sugary icing, might trigger a blood sugar of 140-250 mg/dl, much worse. But that doesn't make the lower blood sugar following pasta any less bad--it's still terrible.

Another issue: GI is assessed over a 2-hour timeline. What if blood sugar remains high in a sustained way, say, over 6 hours? That's precisely what whole wheat pasta will do: Keep blood sugar high for an extended period.

So not only does a low-glycemic index food like pasta increase blood sugar in most of us extravagantly, it does so in a sustained way.

Lastly, low-glycemic index pasta still triggers small LDL particles to an extreme degree, as I discussed in the previous Heart Scan Blog post, Small LDL: Complex vs. simple carbohydrates.

Don't be false reassured by the notion of low GI or GL. In fact, I'd go so far as to say that NO glycemic index is a GOOD glycemic index (or load). The foods we want to dominate our diet are the foods that aren't even listed in the GI database.
