Heart scan book

20. April 2009 William Davis (0)


There are only two books on heart scans available.

One, of course, is Track Your Plaque.

The other is the basic book on heart scans, What Does My Heart Scan Show?

Lost in the navigation column to the left on this blog is the link to get the electronic version of the book. In case you didn't know, we make this available for free.

If you're interested, just go here. This book can provide many basic answers to the questions that often arise regarding heart scans, such as the expected rate of increase in score, how your score compares to other people, when should a stress test be considered. Many heart scan centers use this book for educational purposes to help patients understand the importance of their heart scan scores.

(The sign-up for the book requires that an e-mail address be entered.)

The hard copy of What Does My Heart Scan Show? is available from Amazon, also, for $12.99.

Lies, damned lies, and statistics

18. April 2009 William Davis (8)
In the last Heart Scan Blog post, I discussed the question of whether statin drugs provide incremental benefit when excellent lipid values are already achieved without drugs.

But I admit that I was guilty of oversimplification.

One peculiar phenomenon is that, when plaque-causing small LDL particles are reduced or eliminated and leave relatively benign large LDL particles in their place, conventional calculated LDL overestimates true LDL.

In other words, eliminate wheat from your diet, lose 25 lbs. Small LDL is reduced as a result, leaving large LDL. Now the LDL cholesterol from your doctor's office overestimates the true value.

Anne raised this issue in her comment on the discussion:

I eliminated wheat - and all grains - from my diet nearly three years ago (I eat low carb Paleo). My fish oils give me a total of 1680 mg EPA and DHA per day, and my vitamin D levels since last year have varied between 50 ng/ml and 80 ng/ml. However, my lipid profile is not like either John's or Sam's:

LDL cholesterol 154 mg/dl
HDL cholesterol 93 mg/dl
Triglycerides 36 mg/dl
Total cholesterol 255 mg/dl

My cardiologist and endocrinologist are happy with my profile because they say the ratios are good, no one is asking me to take a statin. My calcium score is 0.


However, if we were to measure LDL, not just calculate it from the miserably inaccurate Friedewald equation, we would likely discover that her true LDL is far lower, certainly <100 mg/dl. (My preferred method is the bull's eye accurate NMR LDL particle number; alternatives include apoprotein B, the main apoprotein on LDL.)

So Anne, don't despair. You are yet another victim of the misleading inaccuracy of standard LDL cholesterol determination, a number that I believe should no longer be used at all, but eliminated. Unfortunately, it would further confuse your poor primary care doctor or cardiologist, who--still believe in the sanctity of LDL cholesterol.

By the way, the so-called "ratios" (i.e., total cholesterol to HDL and the like) are absurd notions of risk. Take weak statistical predictors, manipulate them, and try to squeeze better predictive value out of them. This is no better than suggesting that, since you've installed new brakes on your car, you no longer are at risk for a car accident. It may reduce risk, but there are too many other variables that have nothing to do with your new brakes. Likewise cholesterol ratios.

Aspirin, Lipitor, and a low-fat diet

17. April 2009 William Davis (0)
Despite all the hoopla heart disease receives in the media, I continue to marvel at how many people I meet who still think that aspirin, Lipitor, and a low-fat diet constitute an effective heart attack prevention program.

It doesn't. No more than washing your hands prevents all human infections. It helps, but it is a sad substitute for a real prevention program.

Of course, aspirin, Lipitor, and a low-fat diet is the same recipe followed by the unfortunate Tim Russert and his doctors. You know how that turned out. Mr. Russert's experience is far from unique.

What is so magical about aspirin, Lipitor and a low-fat diet?

There is a simple rationale behind this approach. Aspirin doesn't reduce atherosclerotic plaque growth, but it inhibits the propagation of a blood clot on top of a coronary plaque that has "ruptured," thereby reducing likelihood of heart attack (which occurs when the clot fills the artery). So aspirin only provides benefit if and when a plaque ruptures.

Lipitor and other statin drugs reduce LDL cholesterol, promote a modest relaxation of constricted plaque-filled arteries (normalization of endothelial dysfunction), and exerts other effects, such as inflammation suppression.

A low-fat diet is intended to reduce saturated fat that triggers LDL cholesterol formation and to encourage intake of whole grains that reduce cardiovascular events and LDL cholesterol.

If that is the extent of your heart disease prevention program, you will have a heart attack, bypass surgery, or stent--period. It may not be tomorrow or next Friday, or even next month. Aspirin, Lipitor, and a low-fat diet may delay your heart attack or procedure for a few years, but it will not stop it.

Some flaws in the aspirin, Lipitor, low-fat program:

--Aspirin can only exert so much blood clot-blocking effect. It can be overwhelmed by many other factors, such as increased blood viscosity, increased fibrinogen (a blood clotting protein that also triggers plaque), and plaque inflammation.
--Lipitor reduces LDL, but does not discriminate between the relatively harmless large LDL and the truly plaque-triggering small LDL--it reduces all LDL, but small LDL can still persist, even at extravagant levels since neither aspirin nor Lipitor specifically reduces small LDL, while a low-fat diet increases small LDL.
--Low-fat diet--A diet reduced in fat and loaded with plenty of "healthy whole grains" will trigger increased small LDL (an enormous effect), c-reactive protein, high blood sugar, resistance to insulin, high blood pressure, and an expanding abdomen ("wheat belly").


Aspirin, Lipitor and a low-fat diet do not address:

--Vitamin D deficiency
--Omega-3 fatty acid deficiency and the eicosanoid path to inflammation
--High triglycerides
--Small LDL particles
--Distortions of HDL "architecture"
--Lipoprotein(a)--the worst coronary risk factor nobody's heard of
--Thyroid status

In other words, the simple-minded, though hugely financially successful, conventional model of heart disease prevention is woefully inadequate.

Don't fall for it.

Statin drugs for everybody?

17. April 2009 William Davis (10)
Who is better off?

John takes Crestor, 40 mg per day:

LDL cholesterol 60 mg/dl
HDL cholesterol 60 mg/dl
Triglycerides 60 mg/dl
Total cholesterol 132 mg/dl



Or Sam:

LDL cholesterol 60 mg/dl
HDL cholesterol 60 mg/dl
Triglycerides 60 mg/dl
Total cholesterol 132 mg/dl

who obtained these values through vitamin D normalization (to increase HDL); wheat elimination (to reduce triglycerides and LDL); and omega-3 fatty acids (to reduce triglycerides).


Believe the drug industry (motto: If some statin is good, more statin is better!), then John is clearly better off: He has obtained all the "benefits" of statin drugs. They refer to the "pleiotropic" effects of statin drugs, the presumed benefits that extend outside of cholesterol reduction. The most recent example are the JUPITER data that demonstrated 55% reduction in cardiovascular events in people with increased c-reactive protein (CRP). Media reports now unashamedly gush at the benefits of Crestor to reduce inflammation.

However, on Sam's program, elimination of wheat and vitamin D both exert anti-inflammatory effects on CRP, typically yielding drops of 70-90%--consistently, rapidly, and durably.

So which approach is really better?

In my experience, there is no comparison: Sam is far better off. While John will reduce his cardiovascular risk with a statin drug, he fails to obtain all the other benefits of Sam's broader, more natural program. John will not enjoy the same cancer protection, osteoporosis and arthritis protection, relief from depression and winter "blues," and increased mental and physical performance that Sam will.

If our goal is dramatic correction of cholesterol patterns and reduction of cardiovascular risk, for many, many people statin drugs are simply not necessary.

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.

Santa Claus is alive . . . and works for the drug industry

12. December 2008 William Davis (7)


Maybe your teenagers no longer believe in Santa Claus, but I assure you: Not only is he alive, I believe that we have evidence that he works for the drug industry!

Psshaww! you say. Yet another rant from that kook, Davis. Who can he pick on next? What other imagined "conspiracies" can he uncover?

Let me recount the evidence and I'll let you decide how damning it all is:

--Christmas is a culture of excess, overeating, celebration: Cookies, candy canes, pie, chocolate, egg nog, more cookies . . . A virtual wheat and sugar frenzy!

--Wheat and sugars make us diabetic!

--What does a diabetic look like? How about big protuberant abdomen, florid cheeks, baggy eyes (from sleep apnea)? The red outfit and beard is optional, of course. Could you think of a better representation of what happens to a person when they eat goodies all the time?


I therefore submit that Santa Claus is at the root of a campaign to cultivate diabetes! Diabetes: a growth industry that is raking in billions of dollars for the drug companies!

I'd bet that Mr. Claus would agree with the dietary advice dispensed by the folks at the American Diabetes Association website:

A place to start is at about 45-60 grams of carbohydrate at a meal. You may need more or less carbohydrate at meals depending on how you manage your diabetes.


Eat more carbohydrates, get fatter in the abdomen, require more medication to keep sugar low. Then start over: eat more carbohydrates, get fatter, more medicines. Kaching!

"You may need more?" Personally, I'd be rendered comatose and helpless if I indulged in such carbohydrate gluttony.

If Mr. Claus were, instead, interested in our health and keeping us non-diabetic, Christmas would be a time for pistachios, almonds, dark chocolates, and tea.

You want health advice? Don't ask Santa Claus!

Another case of aortic valve disease reduced with vitamin D

12. December 2008 William Davis (8)
I watched Seth's aortic valve deteriorate over a two year period.

I was first consulted in 2004 to offer an opinion on Seth's heart scan score of 779 and flagrantly abnormal cholesterol patterns, including triglycerides in the 400 mg/dl range. But I heard a murmur, as well, a murmur of a leaky aortic valve, "aortic valve insufficiency."

Over the next two years, I watched Seth's aortic valve worsen, going from mild leakiness to severe.

In 2006-2007, I tiptoed into vitamin D replacement and asked Seth to add some vitamin D. Time passed and Seth's aortic valve got progressively worse.

Over the past year, However, he's maintained a truly healthy level of vitamin D, with blood levels consistently in the 60-70 ng/ml range.

While Seth's last echocardiogram showed a severely leaky aortic valve, the most recent echo showed mild leakiness ("mild aortic insufficiency")--a dramatic reduction.

I continue to see this in many, though not all, patients with aortic valve disease. Though I've more frequently witnessed either stalled progression or reversal of aortic valve stenosis (stiffness), I've now seen a handful of people with aortic valve leakiness (insufficiency) also reverse.

I've posted about this peculiar phenomenon previously:

Aortic valve disease and vitamin D
More on aortic valve disease and vitamin D

Prior to vitamin D, I had NEVER witnessed any aortic valve disease stop or reverse.

A formal trial at some point would be invaluable.

Track Your Plaque Program Data Tracking Tools

7. December 2008 William Davis (3)
At last: After talking about the new Track Your Plaque community tools for the last year, our data tracking software is now available!



Track Your Plaque is, admittedly, somewhat data-intensive. The basic concept relies on the fact that we track heart scan scores, cholesterol values, lipoprotein values like percent small LDL and Lp(a), vitamin D blood levels, intake of omega-3 fatty acids, etc. Our new data tracking tools will help Members track their data over time.

Even more interesting, you can allow other Members (not required) to view your data for comments and feedback. You can also view the program data of other Members (if they choose to make their data "public") to learn how they are going about stopping and reversing their coronary plaque.

In other words, our graphic data tracking tools are yet another way we are using to acquire a collective wisdom on how to put a stop to coronary heart disease, heart attack, and perverse "let's make money with heart procedures" hospital solutions.

One of the aspects that helps make this work is the sharing of data. So far, the people who have begun to enter their data have all made their information "public." It's not truly "public," but viewable only by other Track Your Plaque Members. Also, Members can, in effect, anonymize their data simply by using a nickname, e.g., heartprotection or hearthawk.

The data tracking tools are in beta-test version, so there are bound to be a few glitches. But we're eager to hear from our Members' experiences on how to improve these tools. Report any problems or make your suggestions on the Track Your Plaque Member Forum--Technical Support.

Yet another reason to avoid fructose

6. December 2008 William Davis (5)
Have you seen the Corn Refiners Association commercial campaigns to educate the American public on the safety of fructose? If you haven't, you can view these interesting specimens on You Tube:

"Get the facts--You're in for a sweet surprise: Fructose is safe in moderation!"

Two Moms

Two lovers


Beyond the fact that fructose stimulates liver production of glycerol, which thereby increases liver VLDL production and raises blood levels of triglycerides; likely stimulates appetite; increases cholesterol levels; fructose has also been clearly implicated in increasing blood levels of uric acid.

Uric acid is the substance that, in some people, precipitates in joints and causes gout, the painful inflammatory arthritis that has been increasing in prevalence over the last four decades since the introduction of fructose in 1967. While blood levels of uric acid in the early part of the 20th century averaged 3.5 mg/dl, more recent population assessments have averaged 6.0 mg/dl or higher. (Non-human mammals who don't eat processed foods, drink fruit drinks or beer, and don't eat candy have uric acid levels of <2.0 mg/dl.)

Uric acid is looking like it may prove to be an important risk factor for coronary disease and atherosclerotic plaque. It is no news that people with higher blood levels of uric acid are more likely to experience adverse cardiovascular events like heart attack. People with features of the metabolic syndrome also have higher uric acid blood levels; the more characteristics they have, the higher the uric acid level. However, the prevailing view has been that uric acid is simply an accompaniment of these processes, but not causal.

However, more recent observations suggest that increased levels of uric acid may instead be a cause of metabolic syndrome and high blood pressure.

Increased blood levels of uric acid have been shown to:

--Increase blood pressure
--Induce kidney damage (even in the absence of uric acid kidney stones)
--Antagonize insulin responses

A diagnosis of gout is not required to experience all of the adverse phenomena associated with uric acid. (For not entirely clear reasons, some people, perhaps based on pH or other factors, are more prone to trigger crystallization of uric acid in joints, similar to the phenomena of sugar crystallization when making rock candy.)

Which brings us back to fructose, a sweetener that clearly substantially increases uric acid levels. I suppose that the mothers and lovers in the Corn Refiners' commercials are right to a degree: Our kids will survive, as will you and I, despite increases in triglycerides, enhanced diabetic tendencies, amplified appetites, and increased uric acid due to fructose in our diet. We will also likely survive despite being 100 lbs overweight, partly due to the effects of fructose.

But if long-term health is your desire for you and your family, fructose has no role whatsoever to play.

Interestingly, the obviously expensive and slick ad campaigns from the Corn Refiners' videos have triggered some helpful video counterarguments:

High-fructose corn syrup
Conspiracy for Fat America
High-fructose corn syrup truth


A full discussion of uric acid, the scientific data behind uric acid as a coronary risk factor, and the nutritional means to reduce uric acid will be the topic of a thorough discussion in an upcoming Special Report on the Track Your Plaque website.

Free the Animal

4. December 2008 William Davis (10)
Richard Nikoley from the Free the Animal Blog contributes this informative comment:



'Bout 18 months ago, I was at 230 (5'10) and looked awful. I was on Omeprezole for years for gastric reflux, a variety of prescription meds since early 20s for seasonal sinus allergies, culminating finally in the daily, year round squirts of Flonase-esque sprays (the best for control without noticeable side-effects), and finally, Levothroid for about the last 7 years or so, as I had elevated TSH (around 9ish).

My BP was regularly 145-160 / 95-110.

I decided to get busy. I modified diet somewhat, cutting lots of junk carbs, and began working out -- brief, intense, heavy twice per week. BP began coming down immediately, such that within only a couple of weeks I was borderline rather than full blown high. Then after about six months, a year ago, I went to full blown low-carb, high fat, cutting out all grains, sugar, veg oils, etc, and replacing with animal fats, coconut, olive oil. You know the drill. Then, first of the year I felt great and simply stopped all meds, including the thyroid. I also began intermittent fasting, twice per week, and for a twist, I always do my weight lifting in some degree of fast, even as much as 30 hours.

That's when the weight really started pouring off. Take a look:

http://www.freetheanimal.com/root/2008/09/periodic-photo-progress-update.html

http://www.freetheanimal.com/root/2008/08/faceoff.html

In July I figured it's about time for a physical. Here's the lipid panel, demonstrating am HDL of 106 and Try of 47, great ratios all around:

http://www.freetheanimal.com/root/2008/07/lipid-pannel.html

However, my TSH was even higher -- 16ish. It seems odd that I was able to lose 40-50 pounds of fat (10-15 pounds of lean gain for a 30 pound net loss at that time -- now an additional 10 pounds net loss).

One disclosure is that I was drinking too much, almost daily, and quite a bit (gotta save some vices...). Anyway, I'm at the point now where I want to drill down. I know I need to see an endocrinologist and have T3 and T4 looked at, but in advance, I wanted to see if the recent changes I've made could make a difference:

1. Stopped all alcohol.
2. Stopped most dairy, except ghee and heavy cream, and cheese is now used as a "spice," i.e., tiny quantities -- no more milk.
3. 6,000 IU Vit D per day.
4. 3 grams salmon oil, 2 grams cod liver oil.
5. Vit K2 Menatetrenone (MK-4) -- side story: getting off grains reversed gum disease for which I have had two surgeries, then supplementing the K2 DISSOLVED calculus on my teeth within days -- hygienist and dentist are dumbfounded. Stephan (Whole Health Source), who comments here, has an amazing series on K2.


If you view his photos, you'll appreciate just how far he has come.

Overall, Richard's program is wonderful and his pictures clearly display his success. However, Richard, thyroid function is indeed a problem, a problem that needs to be fixed ASAP. Remember, low thyroid function used to be diagnosed at autopsy at which time the coronary arteries and other arteries of the body were found to be packed solid with atherosclerotic plaque, even in young people.

I'd recommend:

1) Consider 200 mcg Iodine per day from kelp if you do not use iodized salt.

2) Seeing your doctor right away for thyroid replacement, hopefully with consideration of your T3 status.

3) A heart scan--Not to lead to procedures, but something for you to track over time as your program improves and thyroid function is restored.

Beyond this, keep up the great work. Great blog, too!

Low Thyroid and Plaque

3. December 2008 William Davis (12)
Having now tested the thyroid status of several hundred patients over the last few months, I have come to appreciate:

1) That thyroid dysfunction is rampant, affecting at least 25% of everyone I see.
2) It is an enormously effective means to reduce cardiovascular risk.


I'm not talking about flagrant low thyroid dysfunction, the sort that triggers weight gain of 30 lbs, gallons of water retention, baggy eyes, sleeping 14 hours a day. I'm talking about the opposite extreme: the earliest, subtle, and often asymptomatic degrees of thyroid dysfunction that raises LDL cholesterol, lipoprotein(a) (Lp(a), a huge effect!), and adds to coronary plaque growth.

Correcting the subtle levels of low thyroid:

1) Makes LDL reduction much easier

2) Facilitates weight loss

3) Reduces Lp(a)--best with inclusion of the T3 fraction of thyroid hormone.

Recall that, 100 years ago, the heart implications of low thyroid weren't appreciated until autopsy, when the unfortunate victim would be found to have coronary arteries packed solid with atherosclerotic plaque. It takes years of low thyroid function to do this. I advise you to not wait until you get to this point or anywhere near it.

I find it fascinating that many of the most potent strategies we are now employing in the Track Your Plaque process are hormonal: thyroid hormones, T3 and T4; vitamin D (the hormone cholecalciferol); testosterone; progesterone; DHEA, pregnenolone. Omega-3 fatty acids, while not hormones themselves, exert many of their beneficial effects via the eicosanoid hormone pathway. Elimination of wheat and cornstarch exert their benefits via a reduction in the hormone insulin's wide fluctuations.

We haven't yet had sufficient time to gauge an effect on coronary plaque and heart scan scores. In other words, will perfect thyroid function increase our success rate in stopping or reversing coronary plaque? I don't know for sure, but I predict that it will. In fact, I believe that we are filling a large "hole" in the program by adding this new aspect.

Fat and fiber composition of nuts

30. November 2008 William Davis (16)


From Mukuddem-Petersen J, Oosthuizen1 W, Jerling JC. J Nutr 2005.



If you haven't yet done so, adding raw nuts to your health program yields a broad panel of health benefits.

Contrary to conventional advice, nuts can be eaten in unlimited quantities. Provided they are raw--unroasted, unsalted (since salting only accompanies roasted nuts), not roasted in unhealthy oils like hydrogenated cottonseed or soybean (very common)--they do not make you fat, regardless of the quantity consumed. Beer nuts, honey-roasted nuts, mixed nuts roasted in unhealthy oils with salt added are either fattening or exert other unhealthy effects (e.g., hypertension, rise in Lp(a), and cancer from the hydrogenated fats).

Some notable observations from the chart:

--Hazelnuts and macadamians are the richest in monounsaturates
--Walnuts are the richest in the omega-6 linoleic acid, while also richest in the "omega-3" linolenic acid.
--From a fat composition standpoint, raw cashews and dry roasted peanuts aren't so bad.
--Pistachios figure pretty favorably in this analysis, rich in monounsaturates.
--Coconuts are unusually rich in saturated fat, though about half is lauric acid--an issue for future conversation.



Here's a listing of the fiber composition of nuts per 1 oz serving (about a handful):

Almonds (24 nuts) 3.5 g
Brazilnuts, dried (6-8 nuts) 2.1 g
Cashew nuts, dry roasted, with salt added (18 nuts) 0.9 g
Hazelnuts or filberts 2.7 g
Macadamia nuts, dry roasted, with salt added (10-12 nuts) 2.3 g
Mixed nuts, dry roasted, with peanuts, with salt added 2.6 g
Peanuts, all types, dry-roasted, without salt 2.3 g
Pecans (20 halves) 2.7 g
Pine nuts, dried 1.0 g
Pistachio nuts, dry roasted, with salt added (47 nuts) 2.9 g
Walnuts, English (14 halves) 1.9 g

Data courtesy USDA Nutrient Database


Note that almonds are the winners with 3.5 grams fiber per ounce, pistachios a close second. Pine nuts and cashews place last on the fiber content chart.

Not addressed by the charts is protein content of nuts, as well as the low sugar content, all additional beneficial aspects of nuts. Nuts are also a moderate source of magnesium (though seeds like pumpkin and sunflower shine in the magnesium content area).

Rather than micromanage the specific fat and fiber content of your diet, why not get a little of the good of everything on the list and just mix and match the nuts? (Mixed and matched on your own, of course, not a hydrogenated cottonseed oil nut mixture).

Flush-free niacin kills

29. November 2008 William Davis (12)
Here, I re-post a conversation I've posted before, that of the scam product, "no-flush" niacin, also known as "flush-free" niacin.

I find this issue particularly bothersome, since I have a patient or two each and every week who forgets the explicit advice I gave them to avoid these scam products altogether. Despite costing more than conventional niacin, they exert no effect, beneficial or otherwise. Niacin--the real thing--exerts real and substantial beneficial effects. No-flush or flush-free does nothing except drain your wallet. I continue to marvel at the fact that supplement manufacturers persist in selling this product. Ironically, it commands a significant premium over other niacin forms.

They are outright scams that should be avoided altogether.


My former post, No-flush niacin kills:

Gwen was miserable and defeated.

No wonder. After a bypass operation failed just 12 months earlier with closure of 3 out of 4 bypass grafts, she has since undergone 9 heart catheterization procedures and received umpteen stents. She presented to me for an opinion on why she had such aggressive coronary disease (despite Lipitor).

No surprise, several new causes of heart disease were identified, including a very severe small LDL pattern: 100% of LDL particles were small.

Given her stormy procedural history, I urged Gwen to immediately drop all processed carbohydrates from her diet, including any food made from wheat or corn starch. (She and her husband were shocked by this, by the way, since she'd been urged repeatedly to increase her whole grains by the hospital dietitians.) I also urged her to begin to lose the 30 lbs of weight that she'd gained following the hospital dietitians' advice. She also added fish oil at a higher-than-usual dose.

I asked her to add niacin, among our most effective agents for reduction of small LDL particles, not to mention reduction of the likelihood of future cardiovascular events.

Although I instructed Gwen on where and how to obtain niacin, she went to a health food store and bought "no-flush niacin," or inositol hexaniacinate. She was curious why she experienced none of the hot flush I told her about.

When she came back to the office some weeks later to review her treatment program, she told me that chest pains had returned. On questioning her about what she had changed specifically, the problem became clear: She'd been taking no-flush niacin, rather than the Slo-Niacin I had recommended.

What is no-flush niacin? It is inositol hexaniacinate, a molecule that indeed carries six niacin molecules attached to an inositol backbone. Unfortunately, it exerts virtually no effect in humans. It is a scam. Though I love nutritional supplements in general, it pains me to know that supplement distributors and health food stores persist in selling this outright scam product that not only fails to exert any of the benefits of real niacin, it also puts people like Gwen in real danger because of its failure to provide the effects she needed.

So, if niacin saves lives, no-flush niacin in effect could kill you. Avoid this scam like the plague.

No-flush niacin does not work. Period.


Disclosure: I have no financial or other relationship with Upsher Smith, the manufacturer of Slo-Niacin.

CT coronary angiography is NOT a screening procedure

28. November 2008 William Davis (3)
I've recently had several hospital employees tell me that their hospitals offered CT coronary angiograms without charge to their employees.

Among these hospital employees were several women in their 30s and 40s.

Why would young, asymptomatic, pre-menopausal women be subjected to the equivalent of 100 chest x-rays or 25 mammograms? Is there an imminent, life-threatening, symptomatic problem here?

All of these women were without symptoms, some were serious exercisers.

There is NO rational justification for performing CT coronary angiography, free or not.

What they really want is some low-risk, yet confident means of identifying risk for heart disease. Cholesterol, of course, is a miserable failure in this arena. Framingham risk scoring? Don't make me laugh.

Step in CT coronary angiography. But does CT coronary angiography provide the answers they are looking for?

Well, it provides some of the answers. It does serve to tell each woman whether she "needs" a heart procedure like heart catheterization, stent, or bypass surgery, since the intent of CT angiography is to identify "severe" blockages, sufficient to justify heart procedures.

Pitfalls: Because of the radiation exposure, CT angiography is not a procedure that can be repeated periodically to reassess the status of any abnormal findings. A CT angiogram every year? After just four years, the equivalent of 400 chest x-rays will have been performed, or 100 mammograms. Cancer becomes a very real risk at this point.

CT angiography is also not quantitative. Sure, it can provide a crude estimation of the percent blockage--the value your cardiologist seeks to "justify" a stent. But it does NOT provide a longitudinal (lengthwise) quantification of plaque volume, a measure of total plaque volume that can be tracked over time.

What's a woman to do? Simple: Get the test that, at least in 2008, provides the only means of gauging total lengthwise coronary plaque volume: a simple CT heart scan, a test performed with an equivalent of 4 - 10 chest x-rays, or 1 - 2.5 mammograms.

Perhaps, in future, software and engineering improvements will be made with CT coronary angiography that reduce radiation to tolerable levels and allows the lengthwise volume measurement of plaque. But that's not how it's done today.

The Wheat Deficiency Syndrome

26. November 2008 William Davis (21)
Beware the dreaded Wheat Deficiency Syndrome.

Like any other syndrome, you can recognize this condition by its many tell-tale signs:

--Flat abdomen
--Rapid weight loss
--High energy
--Less mood swings
--Better sleep
--Diminished appetite
--Reduced blood sugar
--Reduced blood pressure
--Reduced small LDL and total LDL
--Increased HDL
--Reduced triglycerides
--Reduced C-reactive protein and other inflammatory measures


Of course, you could choose to cure yourself of this syndrome simply by taking the antidote: foods made with wheat flour, like bread, breakfast cereals, pastas, pretzels, crackers, and muffins.

All the signs of the syndrome will then disappear and you can have back your protuberant abdomen, irrational mood swings, exagerrated appetite, higher blood sugar, etc.
