An exercise in optimism

Followers of the Track Your Plaque program already know that maintaining an optimistic viewpoint is important in gaining control over coronary plaque.

In fact, I believe that, in many cases, a sense of optimism may make or break your CT heart scan score-reducing efforts. Pessimists rarely drop their score, while optimists do so all the time.

This week posed a challenge to my optimism. I spent the last week on jury duty hearing the details of a murder case. For four days, I listened to blow-by-blow testimony about the totally pointless, unprovoked death of a young man by a drug-dealing thug. Much of the witness testimony was from people who shared the hopeless, violent world of the defendant.

I was, however, completely impressed by the dedication of the prosecuting attorney, a 50-some year old man who was clearly deeply dedicated to his mission and didn't once provide any indication that he was grandstanding or looking for some personal glory. He was doing his job and trying to obtain justice for the fallen victim. I was equally impressed by the judge, who seemed unfazed by the events but carefully explained why the system worked the way it did. After the trial, he provided some further insights to us jury members and I saw him as a human being who, like the prosecutor, was trying to make a small contribution to making the world better.

Though many of the witnesses who testified against the defendant shared his world, I was impressed with their courage in coming forward. They face the threat of reprisals, I'm sure, for coming forward to the law and testifying against a known career criminal. Several of them said that they were not after any reward, but simply wished to do the right thing and provide testimony that proved damning against the defendant.

I acted as the jury foreman and I was proud of how the jury members listened carefully, asked intelligent and probing questions, and then helped us render a confident and expeditious sentence: guilty.

If anything, despite the tragic circumstances, I was much heartened at how all the participants in this process played their part and justice (at least in the legal sense) was served.

Let optimism prevail, even in dire circumstances.

No need to re-invent the wheel

I seem to be repeating myself lately, but I think this does bear repeating:

There's no need to re-invent the wheel when it comes to gaining control over your heart scan score.

The Track Your Plaque program is the most powerful approach known to help you gain control over your coronary atherosclerotic plaque and CT heart scan score, bar none. While 100% of people do not drop their score, more and more people every week are doing so. (One of the admitted weaknesses of the Track Your Plaque website is our failure to list more success stories; we're working on it.)

The basic program is quite simple:

--The Rule of 60 for lipids (LDL 60 mg/dl; HDL 60 mg/dl or greater; triglycerides 60 mg/dl or less)

--Identify hidden causes of plaque, esp. small LDL, Lp(a), and IDL, followed by specific corrective action

--Fish oil--minimum 1200 mg per day of EPA + DHA

--Normal vitamin D3 blood levels (We aim for 25-OH-vitamin D3 of 50-60 ng/ml)

--Normal blood sugar (<100 mg/dl)

--Normal blood pressure (<130/80)

--An optimistic attitude



Much of the other stuff--vitamin K, matrix metalloproteinase reducing strategies, flavonoid strategies, exercise-induced hypertension, etc.--are, for the majority, fluff. Their real role is in people who may have failed in stopping the rise of their heart scan score just doing the basics of the program.

If you neglect the basics, hoping to find some magic potion, I'm afraid the overwhelming likelihood is that you will fail. I've seen it happen time and again. Someone will come to my office with an extraordinary list of supplements--hawthorne, dozens of anti-oxidants, EDTA, concentrated flavonoid preparations, and on and on. Not only is it shockingly expensive to do this, it's also unnecessary and foolhardy. This kind of unfocused, hocus-pocus in the hopes of getting it right fail time after time.

The Track Your Plaque program, while not foolproof, is the best I know of. Stick to the basics and wander off when the basics fail. But there's extraordinary power in just achieving the basics.

Are we a front for drug companies?

I was shocked recently when someone accused me and the Track Your Plaque website of being nothing more than a front for the drug industry, that we are promoting concepts with the hidden pharmacuetical agenda behind us.

Don't make me laugh. How in the world that kind of impression could be gotten from either the Heart Scan Blog or the Track Your Plaque website is beyond me.

But I occasionally do need to state explicity: We do not promote drugs, neither this Blog nor the Track Your Plaque website has ever sought nor been backed by pharmaceutical money. The only money that supports this website is our own and that from paying Track Your Plaque members.

In fact, I am quite proud of the unbiased content and commentary on both venues. I challenge anyone to point out how and where there is any suggested relationship to a hidden source of commercial backing. I assure you, there is none.

If I say a drug is worth you and your doctor considering, then I say so with a true belief in it, not because somebody or some company paid me to say so. If I say a drug stinks, I believe that too. If we use a specific supplement in the program, it's because we believe it truly adds value to a plaque-reversal program. We receive no money from drug, supplement, or other commercial interests to promote their products. Period.

What is "normal"?

When it comes to laboratory values and medical testing, a common dilemma is knowing what is "normal." Let me explain.

First of all, when you receive a laboratory result for a test, a "reference range" or "normal range" is usually provided. Where did that range come from?

It varies from test to test. For instance, a low potassium is easy, because low potassium levels can lead to life threatening consequences, e.g., dangerous heart rhythms. High potassium likewise, because dangerous phenomena develop when potassium generally exceeds 5.5 mg/dl or so.

But what about something like HDL or LDL. Here's where confusion reigns. Often, "normal" is obtained by taking the average and saying that any value plus or minus two standard deviations (remember that painful class?) represents normal or reference range.

If that were true, what if we applied that principle to body weight. If we weighed several thousand adult women, the average would be in the neighborhood of 172 lbs (no kidding). Does that mean that 172 lbs plus or minus two standard deviations is normal? No, of course not.

There is therefore a distinction between "normal" and "desirable". For HDL cholesterol, your laboratory report might say that an HDL cholesterol of 40-60 mg/dl is normal. But is it desirable? I don't think so. The most frequent HDL level for a male with a heart attack is 42 mg/dl--hardly desirable.

Let's take triglycerides. The average triglyceride level in the U.S. is somewhere around 140 mg/dl. For those of us who do a lot of lipoprotein testing, we can tell you that triglycerides at this level, though generally regarded as being within the normal range, are associated with flagrant and obvious excesses of several abnormal lipoprotein particles that contribute to coronary plaque growth (VLDL and often IDL; small LDL; drop in HDL and shift towards small HDL).

So, always take the so-called "normal" or "reference" values on a lab report as crude guidelines that often have little or nothing to do with health or desirability. Unfortunately, many physicians are not aware of this and will declare any value within the normal or reference range as okay. An HDL of 40 mg is not okay. A triglyceride level of 140 mg is also not okay.

What is okay? What is desirable? That depends on the parameter being examined. From a basic lipid standpoint, of course, we regard desirable as 60-60-60. Desirability from a lipoprotein standpoint we will cover in a more thorough Track Your Plaque Special Report in future.

The wisdom of the masses

My sister sent me these quotes:



"We don't like their sound, and guitar music is on the way out."

Decca Recording Co. rejecting the Beatles, 1962


"Stocks have reached what looks like a permanently high plateau."

Irving Fisher, Professor of Economics, Yale University, 1929


"Airplanes are interesting toys but of no military value."

Marechal Ferdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, France


"Everything that can be invented has been invented."

Charles H. Duell, Commissioner, US Office of Patents, 1899



No doubt, conventional wisdom can often be laughably (tragically?) wrong. The problem is that, as absurd as all the above sentiments seem to us now and in retrospect, they represented the view of many people years ago. These views were held by many, including many people in positions of power and decision-making responsibility.

A more relevant but nonetheless laughable and widely held belief in 2007: coronary heart disease should be treated with hospital procedures.

Why is a disease that requires 30 years to develop treated only at the final moments with a procedure? Do you only change your car's oil when the engine is on its last legs? Or, do periodic, relatively effortless oil changes during the life of the car make better sense?

I witness just how brainwashed the public has become with this crazed notion when I meet someone socially at, say a fundraiser or cocktail party. When they ask what I do, I tell them I'm a cardiologist. The invariable response: "Oh, what hospital do you work out of?"

I tell them I don't, that I take care of the majority of heart disease right from the office. 99% of the time I get a puzzled look. If we had comic bubbles above our heads revealing our internal thoughts, it would read "Yeah, right. What a kook."

The notion that coronary heart disease is something that is manageable with simple tools for the majority of us in the early stages is entirely foreign to almost everybody. The hospitals and the medical industry have so succeeded in dazzling the public with images of staff in scrubs, rushing from emergency to emergency, lights flashing, scalpels flying. . . how can you possibly accomplish this at home or anywhere outside of the high-tech world of the hospital?

Well, I'm a cardiologist and I do it every day. We all need a figurative dose of electroshock therapy to shake ourselves of this crazy notion.

How important is l-arginine?

Perhaps more than any other supplement, l-arginine causes frustration and confusion. It’s difficult to find, sometimes quite expensive, and some preparations cause loose stools.

Just how necessary is it?

L-arginine, you’ll recall, is a source of nitric oxide, or NO. Though it’s the same stuff as in car exhaust, NO provides a critical signaling role in your body’s cells that regulate a multitude of functions. Among the important roles of NO is to powerfully dilate, or relax, arteries. A constant flow of NO is required for health, particularly since each molecule persists only a few seconds.

L-arginine is the body’s source of nitric oxide. In addition, a peculiar but very effective blocker of l-arginine called asymmetric dimethylarginine, or ASDM, has recently been discovered to prevent the production of NO. Varied conditions like hypertension, diabetes, high cholesterol, excessive saturated fat or processed carbohydrate intake all lead to heightened levels of ASDM, often several-fold greater levels, and thereby effectively blocking NO production.

The “Arginine Paradox” is the name that some researchers in this field have given to the unusual property of l-arginine supplementation to “overpower” the blocking effects of ASDM. This is somewhat unusual in biologic systems in that an agent that blocks a receptor cannot usually be outmuscled by providing excess material for a reaction. Kind of like hoping that your car runs faster simply by topping up the gas tank.

Concrete observable benefits have been made for l-arginine in clinical trials, such as arterial relaxation that results in arterial enlargement (which can actually be seen in the cath lab); anti-inflammatory effects; reduction of blood pressure; enhancement of insulin responses, etc. All of these effects can be connected to beneficial properties that may facilitate atherosclerotic plaque regression and, indeed, there are limited data to document that this is true.

Drug companies may be greedy, but they’re not stupid. They’ve been vigorously pursuing this line of research for some years, a research path that led inadvertently to the erectile dysfunction agent, sildenafil (Viagra), and all its subsequent competitors. (Erectile dysfunction is another expression of endothelial dysfunction, since male erections are driven by the ability to dilate penile arteries.) The wonderful properties of NO enhancement continue to occupy research labs around the world.

Wow. So what’s the reluctance? In the early years of the Track Your Plaque program (meaning just a short 7-8 years ago), I was thoroughly convinced that l-arginine was a crucial, necessary part of a plaque regression program. Without it, you would rarely succeed. With it, the odds were tipped in your favor.

However, something curious has emerged recently. I’ve seen more and more people dropping their heart scan scores. Not just a little bit, but a huge amount. Witness our most recent record holder, Neal, who dropped his score 51% in 15 months. Just five years ago, this magnitude of reversal was unimaginable. Granted, Neal is our record holder, but others are obtaining 10, 18, 24, 30% drops in scores all the time. Many have done it without l-arginine.

Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score.

My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time.

There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden.

Track Your Plaque and non-commercialism

If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site.

We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent.

That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products.

Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info?

Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage.

I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation.

I'd welcome any feedback either through this Blog or through the contact@cureality.com.

The nattokinase scam

A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase.

The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification.

Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts.

Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase.

Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."

Don't you believe it. This is patent nonsense. There are several problems with this rationale:

--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right.

--Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them.

The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?

Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.

Blood pressure with exercise

Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.

Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.

We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.

Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)

I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).

Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.

Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.

The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.

Vitamin D2 vs. vitamin D3

An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.

Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.

The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.

However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.

Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.

D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness.

25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.

Jogging does NOT cause heart disease


Periodically, I'll come across a knuckleheaded report like this one from Minneapolis:

Marathon Man’s Heart Damaged by Running?


Of course, the obligatory story about how a cardiologist came to the rescue and "saved his life" with a stent follows. In other words, a stent purportedly saved the life of this vigorous man with no symptoms and high capacity for exercise.

Does vigorous exercise, whether it's marathon running, long-distance biking, or triathlons, cause coronary disease? Should all vigorous athletes run to their doctor to see if they, too, need their lives to be "saved."

Let me tell you what's really going on here. People with the genetic pattern lipoprotein(a), or Lp(a), tend to be slender, intelligent and athletic. For genetic reasons, these people gravitate towards endurance sports like long-distance running. Lp(a) is a high-risk factor for coronary disease. It is the abnormality present in the majority of slender, healthy people who are shocked when they receive a high heart scan score or have a heart attack or receive a stent. (I call Lp(a) "the most aggressive known coronary risk factor that nobody's heard about.")

The association between endurance exercise and heart disease is just that: an association. It does not mean that exercise is causal. Having seen coronary plaque detected with heart scans in many runners, virtually all of whom demonstrated increased Lp(a), I believe that Lp(a) is causal.

Unfortunately, the man in the Minneapolis story, now that his life is "saved," will likely be advised to take a statin drug and follow a low-fat diet . . . you know, the diet that increases Lp(a).

Warning: Your pharmacist may be hazardous to your health

Pharmacists can be very helpful resources when it comes to questions about prescription drugs.

The operant word here is drugs.

What they are most definitely not expert on are nutritional supplements. In fact, a day doesn't pass by without having to dispell one falsehood or another conveyed to a patient about a nutritional supplement by a pharmacist.

Among the more common falsehoods told to patients by pharmacists:

"You have to take Niaspan. Sloniacin doesn't work."

Patent nonsense. A few years back, I was the largest prescriber of Niaspan in Wisconsin. Although I am embarassed to admit it, I also spoke for the company, educating fellow physicians on the value of niacin for correction of lipid disorders.

Then I shifted to Sloniacin due to cost--it costs 1/20th the cost of prescription Niaspan. I examined the pharmacokinetic data (pattern of release in the body), the published literature (e.g., the famous HATS Trial), and have used Sloniacin over 1000 times in patients. In my experience, there is no difference: no difference in efficacy, no difference in safety, no difference in side-effects. There is a BIG difference in price.

Unfortunately, most pharmacists get their information on niacin from the Niaspan representative.


"You shouldn't be taking vitamin D supplements. I have prescription vitamin D here."

What the pharmacist means is that you should replace your vitamin D3, or cholecalciferol--the form recognized as vitamin D by the human body--with the plant form of vitamin D, vitamin D2 or ergocalciferol.

Since when is a plant form of a hormone (vitamin D is a potent hormone, not a vitamin; it was misnamed) better than the human form?

I've previously talked about this issue in a blog post called Vitamin D for the pharmaceutically challenged.

The notion that D2 is somehow superior to the real thing, D3, is absurd. I use D3 only in my practice and have checked blood levels thousands of times. As long as the D3 comes as a gelcap, drops, or powder in a capsule, it works great, yielding predictable and substantial increases in blood levels of 25-hydroxy vitamin D. If it comes as prescription D2 (or over-the-counter D2), I have seen many failures: no increase in blood levels of vitamin D or meager increases.

Prescription status is no guarantee of effectiveness.


"Why do you need iodine? You already get enough from food."

The NHANES data over the last 25 years argue otherwise: Iodine deficiency is growing, particularly as people are avoiding iodized salt and the iodine content of processed foods is diminishing. The explosion in goiters in my office also suggest this is no longer a settled issue.

On the positive side, it is exceptionally easy to remedy with an inexpensive iodine supplement. That is, until the pharmacist intervenes and injects his bit of nutritional mis-information.


I'm not bashing pharmacists. In fact, Track Your Plaque's own Dr. BG has a pharmacy background, and she is an absolute genius with nutritonal supplements. But she is a rare exception to the rule: Most pharmacists know virtually nothing about nutritional supplements. You might as well ask your hairdresser.

"Healthy" people are the most iodine deficient

Ironically, the healthiest people are the most likely to be deficient in iodine.

Why?

Healthy people tend to:

--Avoid iodized salt because of public health advice to limit sodium
--Use sea salt to obtain minerals like magnesium--but sea salt contains little iodine
--Limit meat--Carnivores obtain more iodine than vegetarians or vegans. In one study, up to 80% of vegans were iodine-deficient (Krajcovicova-Kudlackova M et al 2003).
--Exercise--Substantial amounts of iodine are lost through sweating. In a study of high school soccer players, 38.5% were severely iodine deficient, compared to 2% of sedentary students (Mao IF et al 2001).


That is indeed what I am seeing in my office, as well: The healthiest, most attentive to healthy eating, and most physically active are the ones showing up with small goiters (enlarged thyroid glands) and increased TSH and low free T4 levels.

Why am I checking thyroid and talking about iodine? Because even the smallest degree of thyroid dysfunction can double, triple, or quadruple your risk for cardiovascular events. See the posts Is normal TSH too high? and Thyroid perspective update.

What kind of iodine do you take?

The results of the latest Heart Scan Blog poll are in.

204 respondents answered the question:


Do you take an iodine supplement?

The responses:

Yes, I take Iodoral, Lugol's, or SSKI
26 (12%)

Yes, I take potassium or sodium iodide
19 (9%)

Yes, I take kelp tablets or powder
64 (31%)

No, I rely on generous use of iodized salt
23 (11%)

No, I don't supplement iodine at all
66 (32%)

Isn't iodine something you put on cuts and scratches?
6 (2%)


I am heartened by the number of respondents taking iodine in some form. After all, iodine is an essential trace mineral. Without it and health suffers, often dramatically.

However, I am concerned by the percentage of people who don't supplement iodine at all: 32%. Interestingly, this is approximately the proportion of people who come to my office who also do not supplement iodine who are now showing goiters, or enlarged thyroid glands due to iodine deficiency. Goiters lead to hypothyroidism (low thyroid hormone levels), followed by hyperactive nodules, not to mention undesirable effects like weight gain, fatigue, hair loss, constipation, intolerance to cold, higher LDL cholesterol and triglycerides, and heart disease.

11% of respondents report using lots of iodized salt. This may or may not be sufficient to provide enough iodine to prevent goiter and allow normal thyroid function. The success of this strategy depends to a great extent on how often salt is purchased. Salt that sits on the shelf for more than a month is devoid of iodine, given iodine's volatility.

I am also favorably impressed by the number of people who take "serious" iodine supplements like Lugol's solution, Iodoral, or SSKI. Of course, people who read The Heart Scan Blog tend to be an unusually informed, healthy population. The 12% of people in the poll who take these forms of iodine does clearly not mean that 12% of the general population also takes them. But 12% is more than I would have predicted.

On the Track Your Plaque website, we are awaiting an interview with iodine expert, Dr. Lyn Patrick. I'm hoping for some juicy insights.

And you thought gasoline was expensive

In 1995, the Palmaz coronary stent was introduced, the brainchild of Drs. Julio Palmaz and Richard Schatz. Medical device manufacturer, Johnson & Johnson, priced the device at $2500 per stent.

Let's put this into perspective: At just 0.05 grams per 15 millimeter stent, that put the price of the common stainless steel used to manufacture the stent at $22,650,000 per pound.

Only after several competing stents finally made it to market did J&J reduce its price to its bargain price of $1200, or $10,872,000 per pound. And to think that most of us were shocked to find out that the U.S. military paid $200 for a hammer.

Since 1995, a competitive market for stents has developed, pushing prices down. Now, you can purchase a brand-new coronary stent for as little as $4,000,000 per pound.

Medical device manufacturers have been guilty of a degree of greed that would make many Wall Street bankers blush. That's why I call medical devices "the industry of infinite markups."

"Hey buddy, wanna buy some exorphins?"

Dr. Christine Zioudrou and colleagues at the National Institutes of Mental Health got this conversation going back in 1979 with their paper, Opioid peptides derived from food proteins: The exorphins.

Exorphins are exogenously-derived peptides (i.e., short amino acid sequences obtained from outside the body) that exert morphine-like properties. Mimicking the digestive process that occurs in the gastrointestinal tract using the gastric enzyme, pepsin, and hydrochloric acid (stomach acid), Zioudrou et al isolated peptides from wheat gluten with morphine-like activity. They followed this research path because of the apparent association of wheat and mental illness.

In the bioassays used, wheat-derived exorphins competed successfully with the endogenous opiate, met-enkephalin. Interestingly, casein-derived (i.e., casein milk protein) exorphins were also identified that also displayed opiate-binding activity, though less powerfully. The morphine-like activity was also blocked by the drug, naloxone (the same stuff given to people exposed to morphine overdose).

Among the many devastating effects of celiac disease , the immune disease that develops from wheat gluten exposure, are mental and emotional effects, such as anxiety, fatigue, mental "fog," depression, bipolar illness, and schizophrenia, that disappear with removal of gluten. Many parents of autistic children also advocate wheat-free diets for similar reasons.

Among the many wonderful comments posted on the last Heart Scan Blog post, "I can't do it," was Anne's:

I am not the Anne in your post, but I was addicted to wheat. It was my favorite food. I lived on and for breads. Then I discovered I was gluten sensitive and I did go through a withdrawal of about 4 days. After 4 days I noticed my health problems were disappearing. Depression, brain fog and joint pain are 3 of the many symptoms that disappeared. That was 6 yrs ago.

Tell Anne that I had dreams about bread in the beginning - they will pass. Now the donuts, breads, cookies and cakes in the stores and at work don't even look good. In fact, I don't like the smell of bread anymore. It takes time, but the cravings do pass.



Combine wheat"s exorphin-driven addictive potential with its flagrant blood sugar-increasing properties, and you have a formula that:

1) makes you fat
2) increases likelihood of diabetes, and
3) makes you want to keep on doing it.

Reminds me of nicotine.

My personal view: I have absolutely no remaining doubt that wheat products have no place in the human diet. Not only does the research provide a plausible basis for its adverse health effects, but having asked hundreds of people to remove it from their habits has yielded consistent and remarkable health benefits. Just read the reader comments here and here.

"I can't do it"

Anne sat across from me, bent over and sobbing.

"I can't do it. I just can't do it! I cut out the breads and pasta for two days, then I start dreaming about it!

"And my husband is no help. He knows I'm trying to get off the wheat. But then he brings home a bunch of Danish or something. He knows I can't help myself!"

Having asked hundreds of people to completely remove wheat from their diet, I witness 30% of them go through such emotional and physical turmoil, not uncommonly to the point of tears. For about 10-20% of people who try, it is as hard as quitting cigarettes.

Make no mistake about it: For many people, wheat is addictive. It meets all the criteria for an addictive product: People crave it, consuming it creates a desire for more, lacking it triggers a withdrawal phenomenon. If wheat were illegal, there would surely be an active underground trafficking illicit bagels and pretzels.

Withdrawal consists of fatigue and mental fogginess that usually lasts 5-7 days. Just like quitting smoking, wheat withdrawal is harmless but no less profound in severity.

People who lack an addictive relationship with wheat usually have no idea what I'm talking about. To them, wheat is simply a grain, no different than oats.

But wheat addicts immediately know who they are. They are the ones who can't resist the warm dinner rolls served at the Italian restaurant, need to include something made of wheat at every meal, and crave it every 2 hours (matching the cycle of blood sugar peaks and valleys, the "valley" triggering the craving). When they stop the flow of immediately-released glucose that comes from wheat (with blood sugar peaks that occur higher and faster than table sugar), irresistible cravings kick in. Then watch out: They'll bite your hand off if you reach for that roll before they do.

Break the cycle and the body is confused: Where's the sugar? The body is accustomed to receiving a constant flow of easily-digested sugars.

Once the constant influx of sugars ceases, it takes 5-7 days for metabolism to shift towards fat mobilization as a source of energy. But along with fat mobilization comes a shrinking tummy, reducing the characteristic wheat belly.

If you try to quit smoking, you've got "crutches" like nicotine patches and gum, Zyban, Chantix, hypnosis, and group therapy sessions. If you try and quit wheat, what have you got? Nothing, to my knowledge. Nothing but sheer will power to divorce yourself from this enormously destructive, diabetes-causing, small LDL-increasing, inflammation-provoking, and addictive substance.

Spontaneous combustion, vampires, and goitrogens

What do the following have in common:

Lima beans
Flaxseed
Broccoli
Cabbage
Kale
Soy
Millet
Sorghum?

They are all classified as goitrogens, or foods that have been shown to trigger goiter, or thyroid gland enlargement. Most of them do this either by blocking iodine uptake in the thyroid gland or by blocking the enzyme, thyroid peroxidase. This effect can lead to reduction in thyroid hormone output by the thyroid gland, which then triggers increased thyroid stimulating hormone (TSH) by the pituitary; increased TSH acts as a growth factor on the thyroid, thus goiter.

Add to this list of goitrogens the flavonoid, quercertin, found in abundance in red wine, grapes, apples, capers, tomatoes, cherries, raspberries, teas, and onions. Most of us obtain around 30 mg per day from our diet. Quercetin, often touted as a healthy flavonoid alongside resveratrol (e.g., Yang JY et al 2008), has been shown to be associated with reduced risk for heart disease and cancer. Many people even take quercetin as a nutritional supplement.

Quercetin has also been identified as a goitrogen (Giuliani C et al 2008).

What to make of all this?

Most of these observations have been made in in vitro ("test tube") preparations or in mice. Rabbits who consume a cabbage-only diet can develop goiter.

How about humans? The few trials conducted in humans have shown little or no effect. In most instances, the adverse effects of goitrogens have been eliminated with supplemental iodine. In other words, goitrogens seem to exert their ill thyroid effects when iodine deficiency is present. Restore iodine . . . no more goitrogens (with rare exceptions).

Should we as humans adopt a diet that avoids apples, grapes, tomatoes, red wine, tea, onions, soy etc. on the small chance that we will develop goiter?

I believe that we should avoid these common food-sourced goitrogens with as much enthusiasm as we should be worried about spontaneous combustion of humans or the appearance of vampires on our front porches. We are as likely to suffer low thyroid activity from quercetin or other "goitrogens" as we are to experience the "mitochondrial explosions" that are purported to set innocent people afire.

Magnesium and you-Part II

Blood magnesium levels are a poor barometer for true body (intracellular) magnesium.

Only 1% of the body’s magnesium is in the blood, the remaining 99% stored in various body tissues, particularly bone and muscle. If blood magnesium is low, cellular magnesium levels are indeed low—very low.

If blood magnesium is normal, cellular or tissue levels of magnesium may still be low. Unfortunately, tissue magnesium levels are not easy to obtain in living, breathing humans. In all practicality, a blood magnesium test only helps if it’s low, while normal levels don’t necessarily mean anything and may provide false reassurance.

Short of performing a biopsy to measure tissue magnesium levels, several signs provide a tip-off that magnesium may be low:

• Heart arrhythmias—Having any sort of heart rhythm disorder should cause you to question whether magnesium levels in your body are adequate, since low magnesium levels trigger abnormal heart rhythms. In fact, in the hospital we give intravenous magnesium to quiet down abnormal rhythms.
• Low potassium— Low magnesium commonly accompanies low potassium. Potassium is another electrolyte depleted by diuretic use and is commonly deficient in many conditions (e.g., excessive alcohol use, hypertension, loss from malabsorption or diarrhea). Like magnesium, potassium may not be fully replenished by modern diets.
• Muscle cramps— Magnesium regulates muscle contraction. Leg cramps, or “charlie-horses”, painful vise-like cramps in calves, fingers, or other muscles, are a common symptom of magnesium deficiency. (Leg cramps that occur with physical activity, such as walking, are usually due to atherosclerotic blockages in the leg or abdominal arteries, not low magnesium.)
• Migraine headaches—Reflective of magnesium’s role in regulating blood vessel tone, low magnesium can trigger vascular spasm in the blood vessels of the brain. In some emergency rooms, they will actually administer intravenous magnesium to break a migraine.
• Metabolic syndrome—Magnesium plays a fundamental role in regulating insulin responses. Metabolic syndrome (low HDL, high triglycerides, small LDL, high blood pressure, increased blood sugar, excessive abdominal fat, etc.) is triggered by insulin responses gone awry and is clearly linked to low magnesium levels.

The absence of any of these tell-tale signs does not necessarily mean that tissue levels of magnesium are normal.

Then how do you really know? There really is no easy, available method to gauge body magnesium. As a practical solution, we therefore have aimed for maintaining serum levels of >2.1 mg/dl or RBC magnesium (a surrogate for tissue levels) of >6.0 mg/dl. (Going too high is not good either, so occasional monitoring really helps. However, I've only seen this once in a psychotic woman who drank ungodly amounts of magnesium-containing antacids for no apparent reason; she almost ended up on a respirator due to respiratory suppression by the magnesium level of 11 mg/dl!)

In all practicality, because of magnesium’s crucial role in health, its widespread deficiency in Americans, and the growing depletion of magnesium in water, supplemental magnesium is necessary for nearly everyone to ensure healthy levels.

More on magnesium to come.

Lethal Lipids II

I call the combination of low HDL, small LDL, and lipoprotein(a) "lethal lipids," since the trio is an exceptionally potent predictor for heart disease. Uncorrected, the combination is a virtual guarantee of heart disease.

Ed is a perfect example of someone who came to my office recently with this pattern. His starting values:

HDL: 34 mg/dl

Small LDL: 78% of total LDL
NMR: Small LDL 1655 nmol/L; total LDL particle number 2122 nmol/L)

Lipoprotein(a): 205 nmol/L



The atherogenicity, or plaque-causing potential, of this pattern was reflected in Ed's heart scan score of 2133.

You can readily see that, of this combination, only HDL cholesterol would be adequately identified through conventional lipid testing. Small LDL and lipoprotein(a) need to be specifically measured via lipoprotein testing.

And, contrary to the drug industry's "statin drugs for everybody" motto, this pattern, while improved with statin therapy, is not shut off.

Specific correction of each abnormality is required. For instance, niacin addresses all three: increases HDL, reduces small LDL, and (usually) reduces lipoprotein(a). A standard low-fat diet makes this pattern worse by reducing HDL, increasing small LDL, and (usually) increasing lipoprotein(a).
