Is it mainstream or alternative?

24. May 2006 William Davis (0)
A question I get about once a week: "Is your program a kind of alternative medicine?"

Our program for control and reversal of coronary plaque using CT heart scans applies an eclectic panel of tools to achieve its goals. We use high-tech methods like lipoprotein analysis and CT heart scans; nutritional supplements like fish oil, vitamin D, and l-arginine; diet strategies and "functional foods" (using foods as a therapeutic tool); and conventional medication.

I don't consider this approach "alternative" in the sense that it uses unmeasurable or spiritual strategies. But I don't consider it mainstream, either, since current mainstream practice of heart disease prevention is far less rigorous with far less satisfactory results.

I think I can sum up the Track Your Plaque approach by saying that we use tools that work. Our measure of success is whether or not your heart scan score is stopped or reduced--that's hard to fudge. You can call it what you will, but I call it the best program for heart disease prevention I know of, alternative or mainstream.

Want to see someone turn diabetic?

24. May 2006 William Davis (0)
If you want to witness the transformation of someone into a pre-diabetic or diabetic, put them on a low fat diet.

Dr. Dean Ornish's program, detailed in his books, Dr. Dean Ornish's Program for Reversal of Heart Disease and Eat More, Weigh Less , are woefully outdated in 2006. Yet the low fat notion continues to show up in the consciousness of people I talk to about heart disease reversal.

"I'm already on a low fat diet. Do you think my heart scan score has reversed?"

Highly unlikely. What Dr. Ornish (as a non-cardiologist, by the way) failed to recognize is that what he did manage to reverse in a small number of people is something called "endothelial dysfunction", but he did not reverse or shrink coronary plaque.

Given the limitations of technology when the Ornish concept got its start, it appeared as if reversal was obtained. In reality, all his approach accomplished was a relaxation in tone of abnormally constricted arteries, thus giving the appearance of reversal. Increased artery tone, or endothelial dysfunction, is extremely common when atherosclerotic plaque is present.

Any cardiologist will tell you that there are many ways to reverse endothelial dysfunction: exercise, weight loss, cholesterol drugs, drugs for high blood pressure, fish oil, hormonal therapy, vitamin C, l-arginine, etc. There is nothing special about a low fat diet.

In fact, Track Your Plaque followers will recognize that a low fat diet is, in fact, potentially harmful, particularly when low HDL or small LDL is part of your pattern.

Let's bury the outdated ideas of the Ornish low fat diet once and for all. It doesn't work. All it may do is confuse you and set you back from your real coronary plaque reversal program.

Inulin: A fiber for weight loss

23. May 2006 William Davis (10)
Here's an interesting product that seems to be gaining some popularity for weight loss: Inulin.

Not to be confused with "insulin", with which it is completely unrelated, inulin is a naturally-occurring plant fiber. It's found in broccoli, asparagus, celery, etc. Like beta-glucan from oats or pectin, inulin is a so-called soluble fiber, a fiber that assumes a gel-like consistency when exposed to water.

Inulin has the effect of increasing satiety, or the sensation of fullness. This cuts your craving for foods. I've tried it recently and I prefer it over glucomannan, another soluble fiber for satiety.

The people at Stonyfield Farms have been adding inulin to their yogurts from some time. The nutritionist at the company tells me that there's 2-3 grams of inulin per 6 ounce container of their yogurt.

You can also find inulin as a supplement that you can add to foods, available from some health food stores and online supplement companies. I came across a neat product called Fiber Choice that's now being distributed widely throughout the U.S. I tried their Weight Management version. It was a delicous strawberry taste. The label says take two chewable tablets twice a day, but I found that two tablets three times a day somewhat better. It's best taken around 30-60 minutes prior to each meal and it causes you to be fuller with less food. One caution: It'll cause loads of gas, especially in the beginning. For that reason, you might try starting with a smaller dose, or start on the weekends when you have the option of some privacy!

More info on the Fiber Choice product can be found at their website, http://www.fiberchoice.com.

Disclaimer: I have no relationship with the manufacturer of this product. I'm simply passing on some thoughts on my experience with this interesting possibility for weight loss.

Will you recognize the truth when you see it?

23. May 2006 William Davis (0)
Do you ever wonder that, if the truth were given to you, that you'd recognize it as such? Or would you dismiss it as just another bunch of nonsense?

After all, you and I live in the Information Age. It means that we have access to mountains of information like never before in human history. But it also means that the truth is often drowned out by an avalanche of mis-truths, sales pitches and marketing, and just plain nonsense.

This struck me the other day when I was talking to a patient.

64 years old with a high heart scan score placing her at significant risk, she looked confused. I'd just described the multitude of causes of coronary plaque that we'd uncovered. The heart scan alone had been a shocker.

"I don't understand. My doctor told me that I had nothing to worry about. I've known him for years and he knows me really well. He did a stress test. That was fine. I don't get all this other stuff you're telling me--lipoprotein whatever..."

Despite my efforts to help her gain an understanding of our intensive approach, she just became increasingly more frustrated. "I just don't think I can do this."

That's the last I've heard from her. As far as I know, she's returned to the comfort of her family doctor who has reassured her over the years. And perhaps there's some good in that. But I do fear for the day when, unexpectedly, she suffers some catastrophe that we told her was coming sooner or later unless real preventive efforts were started.

You could say that she failed to recognize the truth when it was given to her-- boldly, unadorned, and with far greater scientific certainty than the casual reassurances she was accustomed to. But, unfortunately, that's all that some people want.

Don't neglect the basics in your heart disease reversal program

23. May 2006 William Davis (0)
Carl loved new ideas and novel approaches. You could tell by the sheer number of nutritional supplements he took. His list had grown to 18 different supplements over the past two years.

Carl came to me for coronary plaque regression. Lipoprotein analysis did uncover several previously unsuspected abnormalties, most notably small LDL particles and lipoprotein(a). In addition, Carl's LDL cholesterol ranged between 111 mg-156 mg and he was clearly hypertensive, with systolic blood pressures consistently around 150-160. (Recall that people with Lp(a) are more prone to hypertension.)

Carl was more than willing to have his lipoprotein(a) reduced. We did so with niacin and testosterone and the level dropped to near zero. Likewise, we corrected his small LDL pattern with niacin, fish oil, and a reduction in processed carbohydrates.

But Carl really resisted doing much about his LDL cholesterol and high blood pressure. I got the sense that these "boring" issues simply didn't interest him. After all, LDL cholesterol and blood pressure were the stuff of TV commercials and the popular conversation propagated by drug companies.

Carl's follow-up heart scan, however, finally persuaded him: a 24% increase in one year, likely due to the neglect of the basic issues.

I liken Carl's case to being like the teenager with a new car who polishes the paint to a bright finish, puts new wheels and tires on it, spruces up the interior with various doodads--but then fails to change the oil. Sometimes it's the most basic issues that can diminish your success.

Issues like LDL cholesterol and high blood pressure aren't the most glamorous, but they do count in your coronary plaque control program.

Is your doctor a hospital employee?

21. May 2006 William Davis (0)
There's a disturbing trend that's growing--silently but rapidly.

In Milwaukee, three hospital systems compete for the local health care dollar. To gain more control over revenues and the routing of patients, the hospitals are aggressively hiring physicians to work for them. I've witnessed many of my cardiology colleagues, primary care doctors, and a substantial number of procedural specialists enticed by the offers made by hospital employers.

This phenomenon is not unique to Milwaukee but is being used in many, perhaps most, major cities in the U.S.

This means that physicians are employees of the hospital. That way, employee-physicians are obliged to use only the hospital system that employs them. In the old days, your doctor could use any hospital he/she desired, depending on the quality, location, facilities, etc. Now, many physician-employees are given no choice but to use the hospital that pays their salary.

That by itself is not necessarily bad. But combine salary with incentives for bringing in patients for hospitalization and procedures--that the rub. In other words, physician-employees are incentivized to generate more revenue for the system, just as employees in many other industries.

If you're a salesman for an insurance company, your job is to bring in more business. If you're a worker on an auto production line, you're expected to meet certain quotas. These same principles are now being applied to many physicians.

How does this affect you? Well, if your physician--especially procedure-driven specialists like cardiologists, general surgeons, orthopedists, etc.--is a hospital employee, BEWARE! Do you really need that procedure, or is your doctor suggesting you have a procedure because it will add to his track record?

Prevention? In this model of health care, why bother? It certainly doesn't pay for a hospital to keep you well. Then why should your physician-employee?

Be careful who you're dealing with. If your physician is a hospital-employee, don't bet on getting preventive care. It's more likely you're that just a future source of revenue when it's time for your bypass operation, hip replacement, carotid endarterectomy, etc.

What more powerful argument is there for increased self-empowerment and information for health care consumers?

Take a walking vacation

20. May 2006 William Davis (1)
If you're planning a vacation, why not consider a walking vacation?

The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htm

Lengthier walks may require some advance planning and toting some supplies. Don't forget the water!

From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless.

There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.

Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking!

"Expanded indications for implantable defibrillators"

19. May 2006 William Davis (0)
So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.

It goes on to say: "In January 2005, indications for implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."

Ka-ching!!! Hear the money piling up in the bank?

The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation.

Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack.

Get a heart scan--but then don't delay taking action!

19. May 2006 William Davis (2)
I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week.

Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period.

Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet.

This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future.

Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow.

What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.

The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan.

Feel that nudge in your back?

17. May 2006 William Davis (0)
You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business.

Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"

In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."

Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them.

No BS weight loss

13. April 2009 William Davis (18)
If there's something out there on the market for weight loss, we've tried it. By we, I mean myself along with many people and patients around me willing to try various new strategies.

Maybe you say: "Well that's not a clinical trial. How can we know that there aren't small effects?"

Who cares about small effects? If a weight loss strategy causes you to lose 1.2 lbs over 3 months--who cares? Sure, it may count towards a slight measure of health in a 230 lb 5 ft 3 inch woman. But it is insufficient to engage that person's interest and keep them on track. That little result, in fact, will discourage interest in weight loss and cause someone to return to previous behaviors.

What I'm talking about is BIG weight loss--20 lbs the first month, 40 lbs over 4 months, 50-60 lbs over 6 months.

Right now, there are only three things that I know of that yield such enormous effects:

1) Elimination of wheat, cornstarch, and sugars

2) Thyroid normalization (I don't mean following what the laboratory says is "normal")

3) Intermittent fasting


Combine all three in various ways and the results are accelerated even more.

Self-directed health is ALREADY here

12. April 2009 William Davis (12)
It can't happen.

People are too stupid/ignorant/lazy or simply don't care.

It is irresponsible. People will misuse, abuse, misdiagnose, fail to recognize all manner of medical conditions.


It's all true. Most of the medical establishment believes it. And it is self-fulfulling: If you believe it, it will happen.

But it's not true for everybody. If readers of this blog, for instance, were to view the conversations we have in our Track Your Plaque Forum, you would immediately recognize that we have a following that is more sophisticated and knowledgeable about coronary heart disease than 90% of cardiologists. That is really something. Perhaps they can't put in a stent or defibrillator, but they understand an enormous amount about this disease we are all trying to control and reverse, sufficient to seize control over much of their own healthcare for this process and related conditons.

Anyway, self-directed health is already here. And it's happening on an incredible scale.

Witness:

--Nutritional supplements--Now a $21 billion (annual revenues) phenomenon, booming sales of nutritional supplements are a powerful testimonial to the enthuasiasm of the public for self-directed health treatments. Sure, there are plenty of junk supplements out there, but there are also many spectacularly effective products. Information, not marketing, will help tell the difference. Over the long-run, the truth will win out.

The 1994 Dietary Supplement Health and Education Act has allowed the definition of “nutritional supplement” to be stretched to the limit. "Nutritional supplements" includes obviously non-nutritional (though still potentially interesting) products like the hormones pregnenolone, dehydroepiandrosterone (DHEA), and melatonin to be sold on the same shelf as vitamin C. There are also amino acids, polysaccharides, minerals and trace minerals, herbal preparations, flavonoids, carotenoids, antioxidants, phytonutrients.

In fact, I believe that the nutritional supplement pipeline is likely to yield far more exciting and effective products than the drug research pipeline! And you will have access to all of it--without your doctor's involvement.

--Self-ordered laboratory testing--In every state except New York and California, an individual can obtain his or her own laboratory testing. New services are appearing to service this consumer segment. As more people become frustrated with the silly gatekeeping function of their primary care physician and as more people gain more control over some of their healthcare dollars through medical savings accounts, flex-spending, and high-deductible health insurance, more are shopping for cost-saving, self-ordered lab testing. Even at-home lab tests are becoming available, such as ZRT Lab tests we make available through Track Your Plaque.

(In California, a doctor's order, or an order from a health professional allowed to prescribe, is still required which, for most people, is just a formality. Just ask your doctor to sign the form with the tests you'd like. Only the most cretinous of physicians will refuse, in which case you should say goodbye. New York is the only state in the U.S. that still dunks women to see if they float, divines the entrails of sacrificial cows, and prohibits lab self-testing.)

--Self-ordered medical imaging--Heart scans, full body scans; ultrasound screening for abdominal aneurysms, carotid disease, osteoporosis such as that offered by LifeLine Screening (who does a great job). There's plenty of room here for entrepreneurial types to develop new services, though there will also be battles to fight with hospitals, radiologists, and others invested in the status quo. But it is happening and it will grow.

(By the way, since I've previously been accused of making bundles of money from medical imaging: I have never--NEVER--owned and do not currently own any medical imaging facility.)


So the question is not "will it happen?" It is already happening. The question is how fast will it grow to include a larger segment of the public? How much more of conventional healthcare can it include? How can we develop better unbiased information sources, untainted by marketing, that guide people through the maze of choices?

Fire your stockbroker, fire your doctor

11. April 2009 William Davis (10)
Is it yet time to fire your doctor?

I advocate a model of self-directed health, a style of healthcare in which individuals have the right to direct his or her own healthcare with only the occasional assistance of a physician or healthcare provider.

Healthcare would not be the first industry that converted to such a self-directed model. Remember travel agents? Only 15 years ago, making travel plans meant calling your travel agent to book your arrangements. This was a flawed system, because they worked on commission, thereby impairing incentive to search for the best prices. You were, in effect, at their mercy.

The investment industry is another such example, though on a larger scale.

Up until the 1980s, individual investment was managed by a stockbroker or other money manager. Stockbrokers, analysts, and investment houses commanded the flow of investment in stocks, options, futures, commodities, etc. Individuals lacked access to the methods and knowledge that allowed them to manage their own portfolios. Individuals had no choice but to engage the services of a professional investor. This was also a flawed system. Like travel agents, stockbrokers worked on commission. We've all heard horror stories in which stockbrokers churned accounts, making thousands of dollars in commissions while their clients' portfolios shrunk.

That has all changed.

Today, the process has largely converted to discount brokers and online services used by individuals trading and managing their own portfolios. Stockbrokers and investment houses continue, of course, but are competing for a shrinking piece of the individual investment market. Independent investors now have access to investment tools that didn’t even exist 20 years ago. Companies like E-Trade and Ameritrade now command annual revenues of approximately $2 billion each.

Travel agents, stockbrokers . . . is healthcare next? Can we convert from the paternalistic, “I’m-the-doctor, you’re the patient” relationship to what in which you self-direct your own healthcare and turn to the healthcare system only in unique situations?

I believe that the same revolution that shook the investment industry in the 1980s will seize healthcare in the future. In fact, the transition to self-directed health will dwarf its investing counterpart. It will ripple more broadly through the fabric of American life. Health is a more complicated “product,” with more complex modes of delivery, and more varied levels of need than the investment industry.

I predict that the emergence of health directed by the individual, just as the emergence of self-directed investment, will dominate in the coming years.

While I hope you've already fired your stockbroker, and I doubt that anyone on the internet still uses a travel agent, I wouldn't yet fire your doctor altogether. But I believe that we are approaching a time in which you should begin to take control over your own health and begin to reduce reliance on doctors, drugs, and hospitals.

Blast small LDL to oblivion

4. April 2009 William Davis (21)
Here's a graphic demonstration of the power of wheat elimination to reduce small LDL particles, now the number one cause for heart disease in the U.S.

Lee had suffered a stroke due to an atherosclerotic plaque in a brain artery. She also had plenty of coronary plaque with a heart scan score of 322.

Lee began with an LDL particle number (the "gold standard" for measuring LDL, far superior to conventional calculated LDL) of 2234 nmol/L. This is exceptionally high, the equivalent of an LDL cholesterol of 223 mg/dl (drop the last digit). Of this 2234 nmol/L, 90% were abnormally small, with 1998 nmol/L of small LDL particles.

Lee eliminated wheat products from her diet, as well as cutting out sugars and cornstarch. Six months later, her results:

LDL particle number: 1082 nmol/L--a 52% reduction from the starting value and equivalent to an LDL of 108 mg/dl. Small LDL: zero--yes, zero.

In other words, 100% of Lee's LDL particles had shifted to the more benign large LDL simply with elimination of these foods---NO statin drug. (In addition to wheat elimination, she was also taking vitamin D and omega-3 fatty acids at our recommended doses.)

While not everybody responds quite so vigorously due to genetic variation, nor does everyone try as hard as Lee did to eliminate the foods that trigger small LDL, her case provides a great illustration of the power of this strategy.

Buy local, get a goiter

3. April 2009 William Davis (19)
The notion of buying food locally--"buy local"--i.e., food produced in your area, state, or region, is catching on.

And for good reason: Not only do you support your local economy, buying locally saves energy, since food doesn't have to be transported from South America or other faraway locations.

But what about those of us in the Midwest, particularly around the Great Lakes basin, i.e., the region previously known as the "goiter belt"? In the early 20th century, up to a third of the residents of this region had enlarged thyroid glands, or goiters, due to iodine deficiency. Lack of iodine causes the thyroid to enlarge, or "hypertrophy," in an effort to more efficiently extract any available iodine in the blood.

Well, there's been a resurgence of iodine deficiency nationwide with 11.3% of the population severely deficient, representing a four-fold increase since the 1970s.

Why an iodine deficiency? Because more people are avoiding iodized salt, the principal source of iodine for Americans since the FDA introduced its voluntary program for iodization of table salt back in 1924. Approximately 90% of the patients I ask now declare that they use very little iodized table salt. While a few take multimineral or multivitamin supplements that contain iodine, the majority do not. The globalization of the food supply--eat global--however, has softened the blow, since we eat tomatoes from Mexico, blueberries from Argentina, lettuce from the Salinas Valley of California.

Now, we have the growing trend to eat local. In the Midwest, it means that the vegetables, fruits, and meats grown locally will also be iodine depleted, since the soil is also iodine-poor, being so far from the sea.

Ironically, two healthy trends--avoiding salt and eating local--will be accounting for a surge in unsightly neck bulges in the Midwest, as well as an increase in thyroid disease.

The lesson: Avoid salt, eat local, but mind your iodine.

Self-directed thyroid management

2. April 2009 William Davis (9)
Is there an at-home test you can do to gauge thyroid status?

Yes. Measure your temperature.

Unlike a snake or alligator that relies on the sun or its surroundings to regulate body temperature, you and I can internally regulate temperature. The hypothalamus-pituitary-thyroid glands are the organs involved in thermoregulation, body temperature regulation. While the system can break down anywhere in the sequence, as well as in other organs (e.g., adrenal), the thyroid is the weak link in the chain.

Thus, temperature assessment can serve as a useful gauge of thyroid adequacy. Unfortunately, temperature measurement as a reflection of thyroid function has not been well explored in clinical studies. It has also been subject to a good deal of unscientific discussions.

How should temperature be measured? The temperature you really desire is between 3 am and 6 am, while still asleep. However, this is difficult to do, since it would require your bed partner to surreptitiously insert a thermometer into some body orifice without disturbing you. A practical solution is to measure temperature first upon arising in the morning, before drinking water, coffee, making the bed, etc.--immediately.

While traditionalists (followers of Dr. Broda Barnes, who first suggested that temperature reflects thyroid function) still advocate axillary (armpit) temperatures, in 2009 it is clear that axillary temperatures are unreliable. Axillary temperatures are inconsistent, vary substantially with the clothing you wear, vary from right to left armpit, ambient temperature, sweat or lack of sweat, and other factors. It also can commonly be 2-3 degrees Fahrenheit below internal ("core") temperature and does not track with internal temperatures through the circadian rhythms of the day (high temperature early evening, lowest temperature 3-6 am).

Rectal, urine, esophageal, tympanic membrane (ear), and forehead are other means to measure body temperature, but are either inconvenient (rectal) or require correction factors to track internal temperature (e.g., forehead and ear). For these reasons, we use oral temperatures. Oral temperatures (on either side of the underside of the tongue) are convenient, track reasonably well with internal temperatures, and are familiar to most people.

Though there are scant data on the distribution of oral temperatures correlated to thyroid function, we find that the often-suggested cutoff of 97.6 degrees Fahrenheit, or 36.4 C, seems to track well with symptoms and thyroid laboratory evaluation (TSH, free T3, and free T4). In other words, oral temp <97.6 F correlates well with symptoms of fatigue, cold hands and feet, mental fogginess, along with high LDL cholesterol, all corrected or improved with thyroid replacement and return of temperature to 97.6 F.

But be careful: There are many factors that can influence oral temperature, including clothing, season, level of fitness, "morningness" (morning people) vs. "nightness" (night owls), relation to menstrual cycle, concurrent medical conditions.

Also, be sure that your thermometer can detect low temperatures. Just because it shows low temperatures of, say 94.0 degrees F, doesn't mean that it can really measure that low. If in doubt, dip your thermometer in cold water for one minute. If an improbable temperature is registered, say, 97.0 F, then you know that your device is incapable of detecting low temps.

A full in-depth Special Report on thermoregulation will be coming soon on the Track Your Plaque website.

Self-directed health: At-home lab testing

29. March 2009 William Davis (20)
I have a prediction.

I predict that more and more healthcare can and will be obtained directly by the individual--without doctors, without hospitals, without the corrupt profit-at-any-costs modus operandi of the pharmaceutical industry. I predict that, given the right tools, Joe or Jane Q. Public will have the choice to manage his or her own health using tools that are directly accessible, tools that include direct-to-consumer medical imaging (CT scans, ultrasound, MRI, etc.), nutritional supplements (a loosely-defined term, to our advantage), and direct-to-consumer laboratory testing.

Done responsibly, self-directed healthcare is superior to healthcare from your doctor. While no one expects you to remove your own gallbladder, you can manage cholesterol, blood sugar issues, vitamin D, low thyroid, and others--better than your doctor.

As everyone becomes more comfortable with the notion of self-directed health, you will see new services appear that help individuals manage their health. You will see prices for direct-to-consumer medical imaging and lab testing drop due to competition, something that doesn't happen in current insurance-based healthcare delivery. People are being exposed to larger deductibles and/or draw money from a medical savings account and will seek more cost advantages. Such direct-to-consumer competitive pricing will meet those needs. Overall, the presently unsustainable cost of healthcare will decline.

To help accelerate the shift of human healthcare away from conventional paths and divert it towards the individual, we have launched a panel of direct-to-consumer at-home laboratory tests that we are making available on the Track Your Plaque website.

On your own (except in California, which requires a doctor's order or prescription; and NY, the only state in the nation that prohibits entirely), you can now test, in the comfort of your own home with no laboratory blood draw required, parameters including:

--Thyroid tests--Free T3, free T4, TSH
--Lipids
--C-reactive protein
--Vitamin D
--Testosterone
--Progesterone

and others.

As the technology improves, more tests will become available for testing at home. (Lipoproteins are not yet available, but will probably be available within the next few years. That would be an enormous boon to those of us interested in supercharged heart disease prevention and reversal.)

Anyone interested in our at-home testing can just go to the Track Your Plaque lab test Marketplace.

When I first began the Track Your Plaque program around 8 years ago, I saw it as a way for people to learn how to control or reverse coronary atherosclerotic plaque, and I'd hoped that physicians would begin to see the light and become patient advocates in this process. But I have lost hope that most of my colleagues are interested in becoming your advocate in health. They are too locked into the "call me when you hurt" mentality. I now see Track Your Plaque as a way for people to seize control over coronary plaque with minimal assistance from their doctors. Indeed, some of our Members have achieved reduction of their plaque in spite of their doctors.

This is just the tip of the iceberg of what's to come. Brace yourself for a cataclysmic shift in returning health to you and away from those who would profit from your misfortune.

Vitamin D for Peter, Paul, and Mary

27. March 2009 William Davis (15)
Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D.

It means that vitamin D deficiency sustained over many years in:

Peter yields prostate cancer

Paul yields coronary heart disease and diabetes

Mary yields osteoporosis and knee arthritis.


Same deficiency, different diseases.

VDR genotype-determined susceptibility to numerous conditions have been identified, including Graves' thyroiditis, osteoporosis and related bone demineralization diseases, prostate cancer (Fok1 ffI genotype), ovarian cancer, rheumatoid arthritis, breast cancer (Fok1 ff), birth weight of newborns, melanoma and non-melanoma skin cancers, insulin resistance and metabolic syndrome, susceptibility to type I diabetes, Crohn's disease, and neurological or musculoskeletal deterioration with aging that leads to falls, respiratory infections, kidney cancer, even periodontal disease.


Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.

Should we all run out and get our VDR genotypes assessed? So far the data have not progressed far enough to tell us. If, for instance, you prove to have the high-risk Fok1 ff genotype, would you do anything different? Would vitamin D supplementation be conducted any differently? I don't believe so.

Virtually all of us should be supplementing vitamin D at a dose that generates healthy blood levels, regardless of VDR genotype. For those of us following the Track Your Plaque program for coronary plaque control and reversal, that means maintaining serum 25-hydroxy vitamin D levels between 60-70 ng/ml.

As the fascinating research behind VDR genotype susceptibility to disease unfolds, perhaps it will suggest that specific genotypes be somehow managed differently. Until then, take your vitamin D.

Blowup at Milwaukee Heart Scan

26. March 2009 William Davis (20)
A local TV investigative news report just ran a critical report of the goings-on at Milwaukee Heart Scan:

Andy Smith went to Milwaukee Heart Scan. "It passed the smell test like a road kill skunk. I mean it was bad," Smith explained.

Our hidden cameras went inside the high pressure sales pitch. "On a good day I sell eight, nine, 10 people. On a bad day probably three," sales manager Angelo Callegari told us.


What the heck happened?

Let me tell you a story.

Back in 1996, I learned of a new technology called UltraFast CT scanning, or electron-beam tomography (EBT), a variation on the standard CT technology that permitted very rapid scanning, sufficiently rapid to allow visualization of the coronary arteries. Back then, only a few dozen devices had been established nationwide.

But the technology was so promising and the initial data so powerful that I lobbied several hospital systems in town to consider purchasing one of the $1.8 million devices. I was interested in applying this exciting technology for early detection of coronary heart disease in Milwaukee. While administrators from several hospitals listened, they quickly lost interest when they figured out that the scanner was primarily a tool for prevention, and would not be directly useful to increase revenue-generating hospital procedures.

I floundered about for a year, trying to drum up support for obtaining a scanner. The manufacturer of the device, Imatron, put me in touch with a couple from Indiana who were also interested in setting up a scanner and had actually obtained the investment capital to do it. We met and, over the next year, got Milwaukee Heart Scan up and running. I served as Medical Director (but never an investor or owner).

Milwaukee Heart Scan was busy from day one, performing EBT heart scans, as well as CT coronary angiograms as long ago as the late 1990s, virtual colonoscopies, and other imaging tests. We all spent a great deal of time educating the public and physicians on what this technology meant for detection and prevention of disease.

Despite the public's perception that the owners, Nancy and Steve Burlingame, were making a bundle of money, in reality they could barely pay their expenses. As price competition heated up in Milwaukee with the lower-cost competing multidetector scanners cropping up, the Burlingames often did not pay themselves.

My interest was to keep this device afloat. I therefore told the Burlingames that they should pay their bills first--their staff, overhead, the scanner costs, and pay themselves--and not worry about reimbursing me for the (very modest) heart scan interpretation fees. For several years, I read thousands of scans without any compensation. But that was okay with me--I just wanted to be sure this device remained available.

But in 2008, some business people from Chicago contacted Steve Burlingame with prospects of applying a contract model of long-term scanning to patients,i.e.,getting people to sign a several-year contract for discounted imaging. They proposed that Milwaukee Heart Scan offer heart scans for free to get people in the door.

What was peculiar about all this is that none of the four physicians on staff at Milwaukee Heart Scan had any knowledge of these discussions at all, including myself. Personally, I figured something was afoot when I came in to read scans in the summer of 2008. While, ordinarily, there is a single stack of scans to read from the preceding few days, this time there were numerous stacks of scans, hundreds of scans in all. Not a word had been said to me or my colleagues. I quickly figured out (thanks to the staff filling me in) that they had been offering scans for free. Not surprisingly, many people took them up on the offer.

Up until then, I had been readily willing to read heart scans without compensation, provided I could perform scan readings in a modest time commitment every week on the weeks it was my responsibility. But work several hours every day for free? Impossible.

My colleagues and I were deeply upset and concerned and insisted on a meeting with all the people involved, including the Burlingames, who had engineered this new sales program. We expressed serious reservations about what they were doing and insisted that they dramatically scale back the promises being made to people. I personally asked that they fire several of the people they had hired as sales people, given what we thought was unprofessional appearance and behavior.

The Burlingames and their new business partners essentially thumbed their noses at the physicians and ignored our advice. So, of the four physicians (one radiologist, three cardiologists), three of us resigned. (The one remaining cardiologist, I believe, didn't really understand what was going on.)

Apparently, after we left, the hard sales tactics continued. The news media got hold of the story through some understandably disgruntled people, and you know the rest.

The tragedy in all this is that, as wonderful as heart scans are, they don't make money for the people who invest in the technology. In the sad case of Milwaukee Heart Scan, it meant that my former friends, the Burlingames, turned to questionable tactics to make this technology pay.

Make no mistake: Heart scans remain a wonderful medical imaging modality. EBT, in particular, remains a fabulous technology that would--even today--remain the pre-eminent means to image coronary arteries, except that GE (who acquired Imatron some years ago) decided that a more direct path to bigger revenues was to purchase Imatron, then promptly scrap the entire operation, choosing to focus on multidetector technology exclusively.

Don't let the spotty past and petty ambitions cloud the fact that heart scans remain the best way to identify and track coronary plaque. Just don't get tempted by the offer of any free scans "without obligation."

Do you work for the pharmaceutical industry?

24. March 2009 William Davis (30)
In response to my post, Lovaza Rip-off, I received this angry comment:


Very high triglycerides, as you all know, is a very serious and life-threatening condition. Therefore, it is very important that any medication you take for treatment must be FDA proven and scientifically backed. This is true for a few reasons. First, there have been zero studies done to show the effects of Costco brand fish oil pills on patients with high triglycerides. So, you cannot assume, simply because the pills you are taking "claim" to have a certain amount of Omega 3 in the them, that they actually do (supplement labeling is self-submitted by the company, and not regulated by any external or 3rd party agency).

Secondly, the other components in fish oil, and maybe in Costco brand (no one knows because it isn't on the label) can actually inhibit the bioavailablity of Omega 3, most notably, Omega 6. And, nowhere on the Costco label does it tell you how much Omega 6 is in it. We also cannot underestimate the importance of purity with these compounds: a top selling brand of fish oil found stores like CVS was recently recalled because it was found to have large amounts of fire retardant in it! These supplements are NOT regulated by the FDA.

Thirdly, be careful when you compare costs. The cost of hospitalization due to acute pancreatitis (a risk of very high triglycerides) far outweighs the cost of taking Lovaza for even several years. If you have a real disease, you need a real drug. And, until Costco does a prospective long-term clinical trial to show that it lowers triglycerides, it should not be used in place of Lovaza.

Finally, I am a living example of how taking a high-potency supplement form of Omega 3 barely lowered my triglycerides, yet within 2 weeks of being on Lovaza there was a significant difference. I am now at my goal. So, before you knock a company, that, in my opinion, has saved my life, please do your research and do not mislead people into thinking that an Omega 3 is an Omega 3 is an Omega 3. If your insurance covers the most potent, the most pure, and the ONLY proven Omega 3 pill on the market, you should be thankful.


The comment was posted anonymously, so I don't know who it came from. But I can tell who I think it is: Someone who works for the drug industry.

This is a common phenomenon: Large corporations are fearful of the comments that are generated on internet conversations and other media. On the internet, there are actually people whose job it is to do "damage control." I suspect this came from one of them.

Why bother? Surely there are better things to do? Well, that's easy. There are billions of dollars at stake. Lovaza, in particular, is sold on the perception that it is somehow superior. If word gets out that maybe you can achieve the same results at a fraction of the cost . . .

Perhaps the "commenter" should also question whether omega-3 fatty acids can come from eating fish.

As part of my cardiology practice, I provide consultation on complex hyperlipidemias, or unusual lipid abnormalities. I have many patients with something called familial hypertriglyceridemia, a genetic condition that permits triglyceride levels of 500, 1000, even many thousands of mg/dl, levels that, as the anonymous commenter points out, can be dangerous.

I virtually never prescribe Lovaza for these people. In their treatment program, I use simple fish oil supplements, such as that from Costco, Sam's Club, or other retailers. I have not witnessed a single failure in treating these people and reducing triglycerides. People with lesser triglyceride abnormalities likewise respond very nicely to inexpensive fish oil that we can buy at the health food store. (I do rely on useful services like Consumer Reports and www.consumerlab.com to reassure us that no pesticide residues, mercury, or other contaminants are in the brands we use.) Excellent, high-quality fish oil supplements are sold by Carlson, Life Extension, Barlean's, even the Members' Mark brand from Sam's Club.

So, the notion that only prescription fish oil is capable of reducing triglycerides is, in a word, nonsense.

Take that back to your CEO.

Go the distance!

How long should it take to stop or reverse coronary plaque growth? How long will it require to stop your heart scan score of, say, 350, from increasing at the expected rate of 30% per year, slow it down (we say "decelerate") to less than 30%, or stop it altogether? Or, actually reduce your score?

It can vary widely. Several simple patterns do seem to emerge, however. Our experience is that lower scores, particularly less than 100 at the start, are easier to gain control over. Scores of 50 or less, in fact, commonly can return to zero.

Higher scores, particularly those >1000, are more difficult to slow or reduce, though we've done it many times. You'll generally have to try harder and it may take longer. It's not uncommon to not stop plaque growth with a starting score this high until your 2nd or 3rd year of effort.

Sometimes it may take even longer. An occasional person requires four or five years to gain control. And there are, unfortunately, some people who never really gain complete control. They slow plaque growth compared to what it would have been with conventional efforts, but never completely halt growth. Why? Sometimes it's a matter of less than full commitment. Other times, we just don't know. Thankfully, these especially difficult cases are few and the majority enjoy substantial slowing or reversal.

Since, in some people, success may take time, you've got to stick it out. Have you ever gotten lost in a strange city only to find out later that the place you were looking for was right around the corner? It can be the same way with stopping coronary plaque growth. If you start with a score of 1000 and, after two years of effort, you've only slowed growth to 11% per year and then give up in frustration, you may have missed the opportunity to have stopped growth entirely in your third year.

All we can do is tip the scales heavily in your favor. We provide you with the best tools known. You've got to provide the commitment, the consistent effort of taking your supplements or medication, making the lifestyle changes, choosing the right foods and avoiding the wrong ones. But you've got to go the distance and not give up too easily.

What you need is an expert in health!

5. May 2006 William Davis (0)
Where can you find an expert in health?

In my experience, they're hard--very hard--to find.

Your hospital? Certainly not the hospitals I know. The hospitals I know are experts in disease, but not in health. Hospitals are helpful when you're sick. But if you're well and would like to stay that way, there's no reason to hang around a hospital. Prevent cancer, prevent heart disease, stay well? There's no place for this conversation in a hospital.

In fact, hospital staff are among the most unhealthy people I come across. Obesity is a nationwide problem affecting millions of Americans. But it's especially a problem among people who work in hospitals. I shudder in horror when I go to a hospital cafeteria and witness the sorts of food they serve in hospitals and see what the staff eat. Should they be regarded as experts in health?

How about doctors? If you associate with physicians like the ones I know, most have lots of knowledge about disease, but little understanding of health. A rare one has insight and interest in health.

I went to a recent meeting with my cardiology colleagues. Food served: pizza, Coca-Cola, spaghetti, fried onion rings, white bread with butter. They all dug in without hesitation. Over half were miserably overweight. Several were, in fact, diabetic; several more, pre-diabetic. I know that at least several are smokers. Experts in health?

Drug companies? Well, they're interested in health only as far as it provides profits. But health for its own sake? Ask anybody from a drug manufacturer about their views on the nutritional supplement movement and watch them sneer.

Food manufacturers? You mean like Coca-Cola, Pepsi-Cola, Nabisco, and General Mills? How about fast-food operations like McDonald's, Pizza Hut, and KFC?

The message: Know where to look for genuine information on health. You won't get it from hospitals. You won't get it from drug company marketing. For the most part, you can't even get it from your physician.

Instead, you're going to witness a broad movement towards self-empowerment in health, fueled by the internet and services like ours (Track Your Plaque). These are information resources that are not driven by profit, intent on providing truth, and not afraid to reject prevailing views.

It does not mean that hospitals are unnecessary, or that food manufacturers are evil, or that fast food should be legislated out of existence. We live in a capitalistic society, driven by supply and demand. Hopefully, demand is borne from educated choices from informed consumers. That's where information that's reliable, credible, and not profit driven come in.

Lipoprotein(a) and small LDL

4. May 2006 William Davis (1)
It's been my suspicion for some time that the combination of lipoprotein(a), or Lp(a), in combination with small LDL particles is a really bad risk for heart disease. People with this combination seem to have much higher heart scan scores for age than others. This seems to be a pattern that we'll see in the occasional woman less than 50 years old who already has a high heaert scan score. (It's unusual for women to have detectable coronary plaque before age 50.)

Very little data exists to support this idea and we are in the process of performing a small study to see whether it's true or not. My gut sense: it's among the most potent causes of coronary plaque around.

Case in point: Even though I spend a great deal of my time and energy advocating heart disease prevention, I still maintain my hospital privileges and skills. I had to cover one of the emergency rooms in town this past weekend (a requirement to maintain my hospital privileges).

One of the patients I saw was a 40-year old man--we'll call him Roland-- suffering a very large heart attack, a so-called "anterior myocardial infarction", or a heart attack involving the most important front portion of the heart. Thankfully, he came to the ER within 45 minutes after his chest pain started. The situation was immediately obvious and I was called to the ER. We quickly took him to the cardiac catheterization laboratory and put a stent in the left anterior descending artery and flow was restored. His chest pain dissipated over the next few minutes.

Nonetheless, Roland was left with a large area of reduced contraction of his heart muscle. Only time will tell how much recovery he'll have.

Roland was extremely lucky. The majority of people with closure of the artery that he'd experienced die within minutes. He did, in fact, "arrest" briefly, i.e., his heart became electrically unstable, though he recovered promptly.

Along with the multiple tubes of blood we required to run tests for his heart attack management, we had Roland's lipids and other measures sent off, as well. Wouldn't you know: Lp(a) and small LDL. This may have accounted for a heart attack at age 40.

Keep a lookout for this when you have lipoprotein testing. Conveniently, niacin can be used to treat both patterns, though higher doses are generally required for the Lp(a) part of the pattern. It's also my belief that the sort of Lp(a) measurement performed by the Liposcience laboratory (www.liposcience.com) is superior. They use a particle number based measure, not a weight-based measure. It is therefore independent of particle size, which can vary. Further work will, I believe, reveal some very important insights into the dreaded Lp(a).

"Please don't tell my doctor I had a heart scan!"

30. April 2006 William Davis (1)
I overheard this recent conversation between a CT technologist and a 53-year old woman (who I'll call Joan) who just had a scan at a heart scan center:


CT Tech: It appears to me that you have a moderate quantity of coronary plaque. But you should know that this is a lot of plaque for a woman in your age group. A cardiologist will review your scan after it's been put through a software program that allows us to score your images.

Joan: (Sighing) I guess now I know. I've always suspected that I would have some plaque because of my mother. I just don't want to go through what she had to.

CT Tech: Then it's really important that you discuss these results with your doctor. If you wrote your doctor's name on the information sheet, we'll send him the results.

Joan: Oh, no! Don't send my doctor the results! I already asked him if I should get a scan and he said there was no reason to. He said he already knew that my cholesterol was kind of high and that was everything he needed to know. He actually got kind of irritated when I asked. So I think it's best that he doesn't get involved.


This is a conversation that I've overheard many times. (I'm not intentionally an eavesdropper; the physician reading station at the scan center where I interpret scans--Milwaukee Heart Scan--is situated so that I easily overhear conversations between the technologists and patients as they review images immediately after undergoing a scan.)

If Joan feels uncomfortable discussing her heart scan results with her doctor, where can she turn? Get another opinion? Rely on family and friends? Keep it a secret? Read up about heart disease on the internet? Ignore her heart scan?

I've seen people do all of these things. Ideally, people like Joan would simply tell their doctor about their scan and review the results. He/she would then 1) Discuss the implications of the scan, 2) Identify all concealed causes of plaque, and then 3) Help construct an effective program to gain control of plaque to halt or reverse its growth. Well, in my experience, fat chance. 98% of the time it won't happen.

I think it will happen in 10-20 years as public dissatisfaction with the limited answers provided through conventional routes grows and compels physicians to sit up and take notice that people are dying around them every day because of ignorance, misinformation, and greed.

But in 2006, if you're in a situation like Joan--your doctor is giving you lame answers to your questions or dismissing your concerns as neurotic--then PLEASE, PLEASE, PLEASE take advantage of the universe of tools in the Track Your Plaque program.

People tell me sometimes that our program is not that easy--it requires reading, thinking, follow-through, and often asking (persuading?) your doctor that some extra steps (like blood work) need to be performed. The alternative? Take Lipitor and keep your mouth shut? Just accept your fate, grin and bear it, hoping luck will hold out? To me, there's no rational choice here.

Doctor, why do I have heart disease?

30. April 2006 William Davis (0)
I see a great many people in my practice who come for a 2nd opinion regarding their coronary disease.

When I ask patients whether they ever asked their primary doctor or cardiologist why they have heart disease in the first place, I get one of several responses:

1) My doctor said it from high cholesterol.

2) My doctor said it was "genetic" or "part of your family history" and so unidentifiable and uncorrectable. Tough luck.

3) I didn't ask and they didn't tell me.


Let's talk about each of these.

Can heart disease be only from high cholesterol and, if so, can taking a statin cholesterol drug be a "cure"? In the vast majority of cases, in my experience, cholesterol by itself is rarely the only identifiable cause of coronary disease.

Most people have a multitude of causes (e.g., small LDL, low HDL, vitamin D deficiency, concealed pre-diabetic patterns, etc.). This explains why many people with high LDL don't have heart disease and why others with low HDL do have heart disease. High LDL cholesterol is only part of the cause.

Does "genetic" or being part of your family's history also mean unidentifiable and uncorrectable? Absolutely not.

What your doctor is really saying is "I don't know enough to diagnose the causes because I haven't kept up with the scientific literature", or "I don't want to be bothered with this because it takes a lot of time and pays me very little money; I'd rather wait until you need a stent ", or "The drug representatives haven't told me about any new drugs". This is ignorance and laziness at best, greed and profiteering at worst. Don't fall for it. I hope that by now you recognize that the great majority of causes of heart disease are identifiable and correctable.

If you didn't think to ask, now you know that you should. If you and your doctor don't think about why you have coronary plaque in the first place, how can you develop a program to control it?

You need to ask. And you need to get confident answers. "I don't know" or "It's genetic" and the like are unacceptable.

Pill pushers

28. April 2006 William Davis (1)
Have you read the latest cover story from Forbes magazine? It's entitled "Pill Pushers: How the drug industry abandoned science for salesmanship".

It's great reading. (A condensed version is available at the www.forbes.com website: http://www.forbes.com/business/forbes/2006/0508/094a.html. They require you to provide your e-mail address though it's free.)

Drug industry advertising has raised consciousness of all the prescription therapies available for us--that's good. However, they've gone so far overboard trying to squeeze more and more revenues out of drugs that they've cost this country a huge amount in increased health care costs and even lost lives. (Forbes does a great job of summarizing some of these instances.)

Drugs like Lipitor, Crestor, Zocor; diabetes agents; anti-hypertensive agents, etc., that is, medications taken chronically, a huge financial bonanzas for drug companies. Not only do they get $100-200 per month, but they get it month after month after month. That's per drug.

Now not all medications are bad or unnecessary. There are times when they can be truly necessary and beneficial. But don't rely on drug company advertising to tell us when.

Heart disease reversal is getting easier and easier

28. April 2006 William Davis (0)
I've recently observed that more and more of our patients on the Track Your Plaque program seem to be stopping or reducing their heart scan scores. And they're doing it faster, in less time, and with larger drops in score.

I'm not entirely sure why the sudden surge in success. However, I do wonder if adding therapeutic levels of vitamin D--at least in our generally sun-deprived Wisconsin participants--is responsible. However, we've also gotten a lot smarter on how to correct the parameters that seems to have outsized effects on plaque growth, especially small LDL.

Yesterday alone, we had two people we added to our list of successes. One, an attorney, stopped his score in one year, with no change (compared to the expected increase of 30%). Another, a woman from the northeast, dropped her score 10% in one year. Her story is remarkable for beginning at a score >1000. In general, the higher your starting score, the longer it takes to stop or reduce it.

These are just two examples. It seems to be happening at an accelerating pace.

I can only hope that our surge in success (not 100%--yet!) will continue. But, every week, we're adding more and more people to our list of success stories.

A used car lot on every street corner

28. April 2006 William Davis (0)
Imagine that, every day, a parade of used-car salesmen knock on your front door to sell you a special "deal". Day in, day out they knock, expecting you to hear about their offers openly.

Is there any doubt about their intentions or motives? Of course not. They're just trying to profit from selling you a car.

That's how it is in a medical office nowadays. Drug representatives, 5, 6, or more each and every day, promoting drugs. Except that the profits from drugs are far greater than a used automobile, and there's a third party involved in the transaction: you.

Today, a pushy representative came to my office. My staff and I tried to tell him that I was not interested in speaking to him. But he proved such a nuisance that I finally came out to tell him that I objected to the idea of drug reps just hanging around trying to hawk their wares.

He blurted, "Doctor, do you have patients with angina? Our new drug, ranolazine, is perfect. Forget about nitroglycerin, beta blockers, and all that. Here's the latest study proving it's better." He tried to shove a reprint of the study at me.

Getting to the bottom line, I asked, "What does it cost the patient?"

"Well, the co-pay is between $40 and $60. We're not yet well covered by insurance, so it'll cost patients around $200 a month."

Need I say more? Here's a drug that does little more than help relieve anginal chest pains. It doesn't reverse coronary plaque. It won't avoid heart attack, death, or procedures. It just modestly cuts back on the frequency of chest pain. And all for the cost of a single heart scan--a heart scan that could have prevented the entire cascade of symptoms/procedures/medication/hospitalization etc.

Hospitals, drug companies, medical device manufacturers. They're all businesses that thrive on your doctor's failure to detect and control your coronary plaque. Sometimes, even your doctor is part of this conspiracy to squeeze dollars out of human disease. Don't fall for it.

Heart disease reversal at age 77

28. April 2006 William Davis (0)
I met Agnes 18 months ago after she underwent a heart scan that revealed a scary score of over 1100. Although in her mid-70s, this was still a very high score. (Recall that a score this high carries a risk for heart attack and death of 25% per year.) Poor Agnes was a wreck over this unexpected result. "I can't sleep, I can't stop thinking about it!"

She'd undergone the scan because her 44-year old son had a heart scan score of 2200! Unfortunately, he ended up with a bypass operation for very severe disease.

Despite having been seeing a cardiologist in Boston for the last 8 years for a murmur, we uncovered multiple hidden lipoprotein patterns, many of which she shared with her son. Her most notable abnormalities were a low HDL and small LDL. Nearly 100% of all LDL particles were, in fact, small. This pattern also caused her LDL cholesterol to be underestimated by over 40%.

18 months on the Track Your Plaque program and Agnes came into town to get a repeat scan. Her score was 10.2% lower. She'd learned to live with the idea that she had hidden heart disease missed by her doctor and cardiologist for many years. But knowledge of the substantial reversal she'd achieved in the 18 months on the program gave Agnes tremendous peace of mind.

Agnes left the office with a big smile.

If you need a reason to quit smoking...

26. April 2006 William Davis (0)
If you've read Track Your Plaque, you already know my feelings about smoking and coronary plaque. Smoke, and you will lose the battle for control over coronary plaque growth--it will grow and grow until catastrophe strikes.

Nonetheless, this is not sufficiently motivating for some people.

If you need more motivation to quit smoking, just take a look at your heart scan sometime, accompanied by either one of the doctors or technicians at the scan center you choose. After you've had an opportunity to look at your coronary arteries, take a look at the lungs. The heart is in the middle and the lungs are the two large black areas on either side of the heart. (They're not really black; that's just the way the images are color-coded.)

Smokers will see large cavities in their lungs--literally, half-inch to one-inch wide holes that contain only air. Many of them. These represent remnants of lung tissue, digested away and now useless from the damage incurred through smoking.

Non-smokers should see uniform lung tissue without such cavities.

What surprised me early on in my heart scan experience was how little smoking exposure was required to generate these cavities. A 40-year old, for instance, who smoked a half-pack per day for 10 years would have them. Heavier smokers, of course, showed far more extensive cavities.

Officially, these cavities are called "emphysematous blebs", meaning the scars of the lung disease, emphysema.

When I've pointed out these cavities or emphysematous blebs to patients, 9 out of 10 times they immediately become non-smokers. Commonly, they'd exclaim, "I had no idea I was really damaging my lungs!" Most admitted that they were awaiting some bona fide evidence that they were truly doing some harm to their bodies. Well, that's it.

Give it a try if you're struggling.

No flush = No effect

13. November 2006 William Davis (3)


"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan

11. November 2006 William Davis (1)

Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

10. November 2006 William Davis (1)
Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

8. November 2006 William Davis (0)
A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

7. November 2006 William Davis (0)
Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

6. November 2006 William Davis (0)
Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

The Track Your Plaque “Rule of 60”

6. November 2006 William Davis (0)
The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.


HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.


Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.


Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil

5. November 2006 William Davis (12)

The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

3. November 2006 William Davis (0)
Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

3. November 2006 William Davis (2)
Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.

Statin stupid

19. March 2010 William Davis (0)
If we followed the lead of the pharmaceutical industry and my cardiology colleagues, we would all subscribe to the "statins for all" philosophy. There is now $2 billion of clinical "research" to back up this "evidence-based" practice.

I do not endorse this "statins for all" philosophy. I believe it is a product of the raw profiteering of the pharmaceutical industry, who are adept at recruiting physicians to their cause.

But lost in the confusion of tainted studies and over-the-top media saturation is the fact that there are small groups of people who likely do obtain benefit from statin drugs. They would certainly benefit from better informed scrutiny of their lipoprotein and metabolic abnormalities. But treatment may involve statins.

This is entirely distinct from the "statins for all" argument, the simpleminded rule that primary care physicians and cardiologist are told to follow.

Groups who may indeed benefit from statin therapy include:

Homozygous or heterozygous familial hypercholesterolemia--Lacking a receptor for LDL particles, LDL piles up to very high levels in these people. LDLs of 300+ are common and lead to heart disease and stroke at relatively young ages.

Combined mixed hyperlipidemia--Among the one or more genetic defects underlying this condition involves excessive production of apoprotein B and VLDL particles. This leads to high risk for heart disease.

People unable to follow a diet to correct their lipid disorder--I have 80+-year old patients, for instance, who say, "I've eaten this way for 82 years. I'm not going to change now!" In the absence of diet and other efforts (e.g., omega-3 fatty acids from fish oil), drugs may be the answer.

In other words, of the $27 billion annual bill for statin drugs, perhaps a tiny fraction is truly necessary. The majority of people taking statin drugs would not really need them if they had the real answers. But don't let that confuse us: There are some people who do indeed benefit.

Butter and insulin

19. March 2010 William Davis (83)
In a previous post, Atkins Diet: Common Errors, I commented on butter's unusual ability to provoke insulin responses. I offer this as a possible reason why, after a period of effective weight loss on a low-carbohydrate program, inclusion of some foods, such as butter, will trigger weight gain or stall weight loss efforts.

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

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

López et al 2008


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

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

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

Vitamin D as a cardiovascular risk factor gains ground

18. March 2010 William Davis (0)
If you were reading The Heart Scan Blog back in 2007, or read my Life Extension article on vitamin D deficiency as a cardiovascular risk factor, you already knew that vitamin D deficiency is rampant and adds to cardiovascular risk.

Results of a study from the Intermountain Medical Center Heart Institute in Utah bolster the concept that vitamin D deficiency is a cardiovascular risk factor, vitamin D normalization/supplementation reduces cardiovascular risk.

Science Daily reported:

For the first study, researchers followed two groups of patients for an average of one year each. In the first study group, over 9,400 patients, mostly female, reported low initial vitamin D levels, and had at least one follow up exam during that time period. Researchers found that 47 percent of the patients who increased their levels of vitamin D between the two visits showed a reduced risk for cardiovascular disease.


In the second study, researchers placed over 31,000 patients into three categories based on their levels of vitamin D. The patients in each category who increased their vitamin D levels to 43 nanograms per milliliter of blood or higher had lower rates of death, diabetes, cardiovascular disease, myocardial infarction, heart failure, high blood pressure, depression, and kidney failure. Currently, a level of 30 nanograms per milliliter is considered "normal."


Over the past 4 years, people in our program have been enjoying the extravagant benefits of vitamin D restoration. Cardiovascular benefits are becoming better documented and the bone health, cancer-preventing, insulin-normalizing, mood-adjusting, and anti-inflammatory effects likewise.

Atkins Diet: Common errors

18. March 2010 William Davis (74)
No doubt: The diet approach advocated by the late Dr. Robert Atkins was a heck of a lot closer to an ideal diet than the knuckleheaded advice emitting from the USDA, American Heart Association, American Diabetes Association, and the Surgeon General's office.

But having just spent a week with Atkins low-carbers, here are some common errors that I see many make, errors that I believe have long-term health consequences, including impairment of weight loss.

Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods.

Consumption of cured meats--Cured, processed meats, such as sausage, hot dogs, salami, bologna, and bacon, have a color fixative called sodium nitrite, an additive that has been confidently linked to gastrointestinal cancers. Risk is likely dose-dependent: The more you ingest, the greater the long-term risk.

Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

Too many calories--While I agree that "a calorie is a calorie" and "calories in, calories out" are faulty concepts, I have anecdotally observed that long-time low-carbers often trend towards unlimited consumption of food, a phenomenon that seems to result in weight gain, especially in the sedentary. I wonder if this is a reflection of the insulinotropic action of dairy products and other proteins, compounded by the poor insulin responsiveness that develops with lack of physical activity. Factor into this conversation that lower calorie intake extends life, probably substantially (Sirt-2 activation and related phenomena, a la resveratrol). If lower calorie intake extends life, unlimited calorie intake likely shortens life.

Please don't hear this as low-carb bashing--it is not. It is a call to improve diets and not stumble into common traps that can impair heart health, weight loss, and longevity.

Fat Head: Tom Naughton's manifesto for low-carb eating

12. March 2010 William Davis (16)
I just got back from Jimmy Moore's low-carb cruise to the Bahamas.

Among the many interesting people I met on the cruise was the creator of the documentary film, Fat Head, Tom Naughton.

Tom brings both creative insights into low-carbohydrate eating as well as humor. Low-carb eating can be a pretty contentious issue, but Tom made it fun. He will make you laugh about many of the odd notions we have about diet.

Among the best parts of Fat Head is Tom's portrayal of the effects of carbohydrates on insulin and fat metabolism:






Fat Head joins the ranks of films like Food, Inc, that make nutrition information entertaining. For anyone interested in a unvarnished look at diet, weight loss, along with a few laughs along the way, Tom Naughton's Fat Head is worth viewing.

Oatmeal: Good or bad?

11. March 2010 William Davis (67)

You've heard it before: oatmeal reduces cholesterol. Oatmeal producers have obtained permission from the FDA to use a cholesterol-reducing claim. The American Heart Association provides a (paid) endorsement of Quaker Oats.

I've lost count of the times I've asked someone whether they ate a healthy breakfast and the answer was "Sure. I had oatmeal."

Is this true? Is oatmeal heart healthy because it reduces LDL cholesterol?

I don't think so. Try this: Have a serving of slow-cooked (e.g., steel-cut, Irish, etc.) oatmeal. Most people will consume oatmeal with skim or 1% milk and some dried or fresh fruit. Wait an hour, then check your blood sugar.

If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high. If you have mildly increased fasting blood sugars between 100 and 126 mg/dl, postprandial (after-eating) blood sugars will easily exceed 180 mg/dl. If you have diabetes, hold onto your hat because, even if you take medications, blood sugar one hour after oatmeal will usually be between 200 and 300 mg/dl.

This is because oatmeal is converted rapidly to sugar, and a lot of it. Even if you were to repeat the experiment with no dried or fresh fruit, you will still witness high blood sugars in these ranges. Do like some people and pile on the raisins, dried cranberries, or brown sugar, and you will see blood sugars go even higher.

Blood sugars this high, experienced repetitively, will damage the delicate insulin-producing beta cells of your pancreas (glucose toxicity). It also glycates proteins of the eyes and vascular walls. The blood glucose effects of oatmeal really don't differ much from a large Snickers bar or bowl of jelly beans.

If you are like most people, you too will show high blood sugars after oatmeal. It's easy to find out . . . check your postprandial blood sugar.

In past, I recommended oat products, specifically oat bran, to reduce LDL, especially small LDL. I've changed my mind: I now no longer recommend any oat product due to its blood sugar-increasing effects.

Better choices: eggs, ground flaxseed as a hot cereal, cheese (the one dairy product that does not excessively trigger insulin), raw nuts, salads, leftovers from last evening's dinner.

Mustard: Super health food?

6. March 2010 William Davis (32)
Could mustard--yes, the yellow condiment you smear on hot dogs--be a super heart healthy food in disguise?

Consider that mustard contains:

Vinegar

Turmeric

No appreciable sugar


The vinegar slows gastric emptying, resulting in slower absorption of any carbohydrates and a reduced glucose area-under-the-curve. Of the little fats contained (about 3 grams per 1/4 cup), most are desirable monounsaturates. Mustards are relatively rich in selenium, with 20 mcg per 1/4 cup, helpful for protection against cancer and thyroid disease, and magnesium, 31 mg per 1/4 cup.

Turmeric is added to most mustards. One of the constituents of turmeric, curcumin, the substance that confers the bright yellow color, has been a focus of interest for its anti-inflammatory effects. Curcumin has been documented to reduce activity of the inflammatory enzymes cyclooxygenase-2 (COX-2), lipoxygenase, and reduce activity of inflammatory signal molecules, tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1,2,6,8, and 12, and monocyte chemoattractant protein (MCP). Curcumin also has been shown to reduce LDL oxidation, a potentially important step in atherosclerotic plaque formation. Turmeric is used as a tea by Okinawans. (Hmmmm . . . )

Turmeric content of mustard can vary, of course. Likewise, sugar content. Look for mustards that are not sweetened, so avoid honey mustard in particular. Look for hot, brown, horseradish, Dijon, etc. If there is a downside to mustard, it's sodium content, though the 709 mg per 1/4 cup should only be a problem for those who are sodium-sensitive (African Americans, in particular).

So perhaps mustard isn't exactly a super health food. But it may have some bona fide health effects and should be used generously especially if you are concerned about blood sugar and inflammatory phenomena.

Exercise and blood sugar

5. March 2010 William Davis (30)
There is no doubt that exercise yields benefits across a spectrum of health: reduced blood pressure,  reduced inflammation, reduced blood coagulation, better weight control, stronger bones, less depression, reduced risk for heart attack.

Exercise also influences blood sugar. Diabetics understand this best: Exercise reduces blood sugar 20, 30, 50 or more milligrams. A starting blood sugar, for instance, of 160 mg/dl can be reduced to 80 mg/dl by jogging or riding a bicycle. (I recently had brunch at an Indian restaurant with my family. Blood sugar one-hour postprandial: 134 mg/dl. I was sleepy and foggy. I got on my stationary bike and pedalled at a moderate clip for 60 minutes. Blood sugar: 90 mg/dl.)

Could the reduction of blood sugar with exercise be THE reason that exercise and physical activity provide such substantial benefits?

Think about it. Reduced blood sugar:

1) Reduces risk for future cardiovascular events.
2) Reduces glycation of proteins, i.e., reduced glucose binding to proteins like the ones in artery walls and the lenses of your eyes.
3) Reduces blood coagulation
4) Reduces endothelial dysfunction (abnormal artery constriction that leads to atherosclerosis)

This might explain why it doesn't require high levels of aerobic activity to derive benefit from exercise, since even modest efforts (e.g., a 15-minute walk after eating) reduce blood sugar substantially.

The incredible 33-year, 18,000-participant Whitehall study tells us that a postprandial (after-eating) blood sugar of an impossibly-difficult 83 mg/dl is required to erase the excess cardiovascular risk of blood sugar. Could this simply be telling us that physical activity or exercise is required to suppress blood sugars to these low levels?

It makes me wonder if an index of the adequacy of exercise is your post-exercise blood glucose.

Jogging does NOT cause heart disease

14. June 2009 William Davis (20)

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

12. June 2009 William Davis (24)
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

5. June 2009 William Davis (27)
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?

4. June 2009 William Davis (21)
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

2. June 2009 William Davis (5)
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?"

31. May 2009 William Davis (18)
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"

30. May 2009 William Davis (20)
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

26. May 2009 William Davis (17)
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

25. May 2009 William Davis (17)
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

22. May 2009 William Davis (7)
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).
