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.

Throw away total cholesterol!

17. 五月 2006 William Davis (1)

Richard's total cholesterol without treatment was 186 mg/dl. "That's great!" his doctor declared, referring to the conventional dictum that total cholesterols less than 200 carry low risk. Several fingersticks in a mall kiosk set up by a local hospital to check total cholesterols confirmed Richard's low number.

But after Richard's unexpected hospitalization and two stents for severe coronary blockages, he demanded better answers.

Tragically, the answer was there all along: Despite a "favorable" total cholesterol, his HDL ("good") cholesterol was a miserable 32 mg (ideal >60 mg).

Total cholesterol is actually the sum total of HDL cholesterol, LDL cholesterol, with a contribution from triglycerides. That's why a low total cholesterol can conceal a low HDL.

This situation is quite common. And low HDL is accompanied by a constellation of other undesirable causes of heart disease, most notably small LDL.

Don't accept total cholesterol as your sole measure of risk. It's nearly worthless. If you live in Bangladesh or a third world country, well perhaps that's the best you can get. But if you live in the U.S. or developed world, it's absurd to rely on total cholesterol.

Smart Start not so smart

15. 五月 2006 William Davis (2)

Kellogg's has crafted a campaign to support the American Heart Association featuring acress Sela Ward. Her attractive face, familiar to many TV and movie viewers, does add a comforting face to their efforts.

What's in this cereal made by the manufacturers of Pop-Tarts, Cheez-It, Rice Krispies, and Chips Deluxe cookies?

There are, indeed, some healthy ingredients: oat bran, potassium; you can even get a version made with soy protein. But there's sugar listed as the second ingredient. High-fructose corn syrup is also listed prominently. (Remember this issue? High-fructose corn syrup causes overwhelming sugar cravings, causes your triglycerides to skyrocket, and is probably among the principal food ingredients that make you obese.)

Upon detailed questioning of my patients struggling to lose weight, this and products like it are often among the "healthy" foods they've gravitated towards. We spend a great deal of time dissuading them of this idea.

A one-cup serving of Smart Start is low in fat (1 gram) but contains 43 grams of carbohydates, of which there are 14 grams of sugar. There are a meager 3 grams of fiber. To me, this sounds like a cupcake.

The Kellogg's people are exceptionally clever marketers. Partner with the American Heart Association and movie stars? Brilliant!

You should trust food manufacturer advertising about as much as you trust drug manufacturer advertising, which is to say not at all.

Kellogg's sold $10 billion dollars of food products last year. They are the world's leading producer of breakfast cereals. They are a leading producer of convenience foods: cookies, crackers, cereal bars, and frozen waffles under the brands Keebler, Pop-Tarts, Eggo, Cheez-It, Nutri-Grain, Rice Krispies, Famous Amos, and Kashi.

Can they cash in on healthy trends? They'll certainly try.

Does anybody have a normal vitamin D level?

15. 五月 2006 William Davis (0)

We now routinely check everyone's vitamin D blood level at the start of the program. (The measure to obtain is 25-OH-Vitamin D3. This is not to be confused with 1,25-OH2-vitamin D3, which is a kidney function measure.)

Of the 10 people with levels drawn today, none were even close to normal levels (which we define as 50 ng/ml)--not a single one.

The majority were in the range of severe deficiency (<20 ng/ml). Only two had levels in the 30s. None had higher. (Remember: I'm talking about people in Wisconsin, a terribly sunlight-deprived area much of the year. This might not apply quite as vigorously to Florida residents or others in sun-exposed regions.)

Curiously, I've also seen several people this week who had extraordinary quantities of coronary plaque on their heart scans (scores >1000), all of whom had extremely low vitamin D levels. One of these people had fairly unimpressive lipoproteins, with very minimal abnormalities identified. (This is quite unusual, by the way.) It makes you wonder if a profound deficiency of vitamin D is sufficient to act on its own as an instigator of coronary plaque.

The more we examine the issue of vitamin D deficiency, the more fascinating it gets. I suspect we've just scratched the surface and there's a lot more to learn about this tremendously interesting nutrient. Nonetheless, with what we're seeing in our experience, I'm urging everyone to get a blood vitamin D level.

Don't believe your LDL cholesterol!

14. 五月 2006 William Davis (0)

Harry's case is typical. For years, his doctor told him his LDL cholesterol of 123 mg was okay. But a heart scan score of 490 (90th percentile at age 52) made him question just where his coronary plaque came from.

Lipoprotein analysis told a very different story: His LDL particle number was 2400 nmol, meaning his trueLDL was more like 240 mg, nearly double the value of LDL obtained through his doctor. Harry had other sources of risk, too, but the LDL particle number was a clear stand-out.

Why does this happen? How can LDL cholesterol be so terribly inaccurate?

LDL cholesterols obtained in virtually all labs are not measured, they're calculated. The calculation was developed in the 1960s by Dr. Friedewald at the National Institutes of Health and therefore goes by his name (the Friedewald calculation). Dr. Friedewald derived this simple calculation to permit doctors across the U.S. to obtain LDL cholesterols, which were technically difficult to measure in those days by using measured HDL, total cholesterol and triglycerides.

Doctors were told that the only time that the Friedewald calculated LDL was inaccurate was when triglycerides exceeded 400 mg. So most family practitioners and internists still believe that calculated LDL's are, for the most part, quite accurate.

Nothing could be further from the truth. When LDL's are actually meaured, you find that LDL is rarely accurate. In fact, in our experience, inaccuracy of 30-50% is the rule, sometimes 100%. The one telltale hint that calculated LDL is wrong is when HDL is <50 mg--that's nearly everybody.

So what's your LDL? You won't really know unless it's measured. Our preferred method is NMR (LipoScience) LDL particle number, probably the most accurate of all. Second best: apoprotein B, direct measured LDL, and non-HDL. (We'll cover this issue much more extensively in an upcoming report on the www.cureality.com website in an extensive Special Report.)

Are you the exception?

14. 五月 2006 William Davis (0)

I read about 40 heart scans this morning. In the stack was a 41-year old man with a heart scan score of 841.

That's terribly high for anyone, let alone a 41-year old person. He's lucky to find out about this before catastrophe strikes.

People like this worry me. In general, we advise men to consider a heart scan age 40 and older; women 50 and older. If there's anything exceptional about your family history or your own history, then you might notch these numbers down another 5-10 years. For instance, if your Dad had a heart attack at age 43, you might consider a scan at age 35. Or, if you've had diabetes for several years and you're a 42-year old woman, you might think about a scan. (Men tend to develop measurable plaque by heart scans 10 years before women.)

There are no hard and fast rules. It's unusual for a male to have a score >0 before age 40. Likewise, it's very uncommon for a woman to have a score >0 before age 50. But there are occasional exceptions--but they can be very important exceptions.

Our 41-year old man with the score of 841, for instance, probably had a high score since his mid-30s. I've seen several women without any obvious risk factors with scores in the several hundred range in their early 40s.

My rule: When in doubt, opt for safety. Every day, I still read about people in their 30s, 40s, and 50s dying of heart attacks. It shouldn't happen.

When in doubt, get the heart scan. The most you'll lose is the cost of the scan and a modest exposure to radiation. If your score is zero, you know you're safe for the next 5 or more years. But if you have an exceptional score at a young age, take preventive action.

Self-empowerment in health: The new wave in health care

12. 五月 2006 William Davis (0)

Track Your Plaque is just one facet of the broad and powerful emerging wave of self-empowerment in health.

Hospitals, drug and device manufacturers, and the medical establishment don't like this idea. People managing their own health? That's ridiculous! Dangerous! But mostly unprofitable.

Self-empowerment means having easy access to simple, safe, and inexpensive diagnostic tests like heart scans, carotid scans, bone densitometry (for osteoporosis), cholesterol tests, abdominal ultrasound, even brain scans (e.g., CT or MRI) for people with a family history of brain aneurysm.

Opponents of this idea worry about the "false-positives" that come about with broad testing, i.e, detection of abnormalities that are artifactual. Our experience is that false-positives are only an occasional problem with any test. Instead, we find that most people have many true-positives. In CT heart scanning, for example, we find many unsuspected enlarged aortas (potential future aneurysms), valve disorders, and aortic calcium. These are all important in a preventive program. Unfortunately, your doctor's definition of false-positive often means that no corrective procedure or operation is required.

Other evidence that self-empowerment in health is growing:

--The nutritional supplement movement. What better example of power in managing your own health is there than the fabulous array of nutritional supplements available?

--Medications moving to over-the-counter status. Gradually, more and more medications are trickling into availability for you to obtain without a doctor's prescription.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The rapidity and depth of information available on the Internet today is mind-boggling. It will fuel the self-empowerment movement by providing sophisticated information to the health care consumer previously available only through your physician.

--High-deductible health insurance plans. If health care consumers will bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention to minimize long-term costs.

There are more. But the movement is powerful and broad--and unstoppable. Let the establishment with vested interests in preserving the status quo fuss and complain, just like horse and buggy manufacturers did in the early 1900's when the autmobile came along.

Vitamin D deficiency is rampant

12. 五月 2006 William Davis (0)

Today alone I've seen several people with severe deficiencies of vitamin D.

We're now checking everyone's blood vitamin D level at the start of the program. The measure that most accurately reflects your vitamin D status is 25-OH-vitamin D3. This is very confusing to many physicians, who traditionally have thought of 1,25-di-Hydroxy vitamin D3 as the standard test to measure. What they're failing to recognize is that this second measure is a kidney product, not a reflection of vitamin D status.

Using 25-OH-vitamin D3, several people today alone had levels of <10 ng/ml, clearly in the category of severe deficiency (generally regarded as <20ng/ml).

The majority of people we see in the office are Wisconsin residents. It's no wonder they're deficient. Although it's mid-May, we've seen the sun only a handful of days this year. And most of the days have been too chilly to wear short sleeves and shorts to permit sufficient surface area for UV exposure.

Living in a sunny climate, however, is no guarantee that you have sufficient blood vitamin D levels. Two recent studies have shown that 30-50% of the residents of sunny southern Florida and Hawaii are also deficient. (Why, I'm not sure.)

Although our experience thus far is anecdotal in several hundred people, my impression is that people who have normal blood levels of vitamin D (we regard normal as 45-50 ng/ml) have a far easier time of halting or regressing coronary plaque.

Vitamin D is among the most exciting nutritional tools we've come across in a long time. The conversation is making the media, which impresses me tremendously, given the fact that nobody stands to profit financially to any significant degree through vitamin D supplementation.

For a wonderful collection of discussions on vitamin D, go to Dr. John Cannell's website, www.vitaminDcouncil.com. You'll find a huge quantity of scientific background and conversation on the whole idea. I believe you will be thoroughly impressed with just how powerful the argument in favor of vitamin D has become.

What if wheat products were illegal?

11. 五月 2006 William Davis (3)

Imagine if anything made of wheat were illegal: bread, bagels, crackers, pasta, pretzels, donuts, Shredded Wheat cereal, Raisin Bran, pastry, cookies, cakes, cupcakes. . . Your grocery store would then be unable to carry any of these products.

How empty would the grocery store shelves be?

There would be very little. The stores would be filled instead with vegetables and fruits, meats, and dairy products. But aisle after aisle would be empty. There'd be no cereal aisle. There'd be no snack chip aisle. The ordinarily overcrowded bread shelves wouldn't be there.

Bakery? Nope, not there either. Pasta and noodles? Empty. How about cakes and pastries? Also gone.

Getting the picture? American groceries are dominated by wheat products. What would happen to your health and the health of your family if wheat were abruptly removed from your choices? Would you be less healthy?

No. In fact, your health would be hugely improved. You'd lose a significant quantity of weight. Extraordinary numbers of people would lose diabetic or pre-diabetic tendencies. Feelings of sluggishness, sleepiness, and moodiness would dissolve. Blood pressure would be reduced. The incidence of cancer, skin disease, and inflammatory diseases would plumet.

From a plaque control perspective, your HDL cholesterol would rise, triglycerides drop. Small LDL would improve dramatically.

The message: Slash wheat products from your diet. Yes, you'll miss the smell and taste of freshly baked bread. But you'll do it for many more healthy years. And you may do it without a 14 inch scar in your chest.

The sobering tale of small LDL

10. 五月 2006 William Davis (0)

Every day, I learn to respect small LDL more and more.

Small LDL particles, and its evil partner, low HDL, is among the most common reasons why someone fails to fully gain control of coronary plaque and heart disease risk.

Just yesterday, I saw a slender businessman (6 feet 1 inch in height, 186 lb.) whose small pattern persisted despite niacin, fish oil, oat bran, and raw almonds. We generally think of small LDL as an overweight person's pattern, but in some people the genetics are quite powerful and it can be expressed even in slender people.

The solution: More physical activity and exercise; cut back on processed carbohydrates, particularly wheat products like breads, pasta, crackers, breakfast cereals; think about magnesium (see our two recent reports on magnesium on the www.cureality.com membership website, the latest report to be posted this week); be sure sleep is adequate (gauge this by whether you're energetic during the day and don't fall asleep watching TV or movies). Lack of sufficient physical activity in people with sedentary jobs is probably among the most common reason the small LDL pattern persists.

Ignore small LDL and it can be like a hidden cancer in your body, growing and metastasizing (not literally, of course), fueling coronary plaque growth. Be sure your doctor assesses whether you have small LDL if you hope to gain control of your coronary risk.

Burn off the fat

9. 五月 2006 William Davis (0)

If you've ever wondered just how many calories you're burning with various activities like yard work, driving, climbing stairs, etc. go to this great website that will calculate it for you: http://www.caloriecontrol.org/exercalc.html.

Here are some examples:

Dancing for 30 minutes(fast, e.g., tango): 193 calories
Yoga for 30 minutes: 204 calories
Washing the car for 30 minutes: 173 calories
Vacuuming for 30 minutes: 88 calories

(All are for a 170 lb person.)

As you see, physical activity does not necessarily have to consist of exercise. It doesn't require fancy equipment or expensive outfits. But it does require you to keep moving. Sedentary work is among the most common reasons I see in my patients for failing to control weight and its associated lipoprotein patterns, like low HDL and small LDL.

If your work is sedentary, then a minimum of 60 minutes of physical activity per day is necessary to begin to correct weight-related patterns. If you gauge by calories burned, then a useful goal is 500 calories per day in physical activity--at a minimum.

Can vitamin D be a SOLE risk factor?

18. January 2007 William Davis (6)

Here's a crazy question. It occurred to me as I was talking to Drew, a slender, active 54-year old dentist with no bad habits including no smoking.

Drew's heart scan score was 222. His lipoprotein analysis mostly revealed a lot of nothing, which is unusual. The only pattern that showed up was a modestly high LDL of 122 mg/dl with a very slight excess of small LDL. That's it. I would not be satisfied that these were sufficient cause for Drew's level of coronary plaque.

Drew's 25-OH-vitamin D3 level: 15 ng/ml--severe deficiency--despite the fact that his doctor had suggested that he take a vitamin D2 preparation. In other words, Drew had been profoundly deficient, probably for years.

Given the unimpressive cholesterol and lipoprotein values, could vitamin D serve as a trigger for coronary plaque all by itself?

I don't have an answer and know of nobody else who does. However, my opinion is that vitamin D is indeed a potent risk that can cause heart disease as a sole risk factor.

Perhaps it's another piece of circumstantial evidence suggesting that vitamin D has an enormous influence on health, including coronary plaque. Interestingly, the only other health problem Drew has had is prostate cancer, treated a few years ago with prostate removal and radiation. Good evidence suggests that vitamin D deficiency escalates risk of prostate cancer substantially.

By the way, I've seen people taking vitamin D2 preparations, called "ergocalciferol," who are every bit as deficient as those who take no vitamin D at all. Avoid D2 or ergocalciferol preparations: they're worthless.

I'm probably way off here, but vitamin D derivatives are mainstays of topical therapy for chronic plaque psoriasis; I have to wonder if coronary plaque can form if vitamin D is deficient since vitamin D is involved with insulin regulation and insulin and hyperglycemia is also implicated in heart disease; often those with diabetes are found deficient in vitamin D, and they're a population most at risk for heart disease? Makes you wonder, doesn't it?

Dr. Davis

You're absolutely right. There is solid evidence that vitamin D deficiency increases diabetic patterns, including higher blood sugar and insulin levels. Whether this is part of the reason why vitamin D might exert benefits on coronary plaque remains uncertain. I suspect that there are many reasons, this being a major one.

Dr. Prendergast has posted today an astonishing story of benefit from D3. The patient was switched to D2 in an effort to move to generic alternatives and he went rapidly downhill toward death. The mistake was discovered, the patient was switched back to D3 and he immediately recovered.
Here's the link to the short video:

Dr Davis!
   Sometime back I had posted a comment on your entry about wheat. And you had suggested that my Vitamin D3 levels might be low. Your diagnosis from 3000 miles away proved right! I had a 25-OH-D3 test and the value was less than 4ng/ml. I consulted my cardiologist and he brushed away the fact and asked me to drink more milk! I'm planning to switch doctors now.
   My copy of TYP reached me and I'm through cover to cover. The level of  details in the book is amazing and I've started correcting my lifestyle, food habits and medicines(of course, after discussing with the doctor).
   Many doctors here prefer a CT angiogram to a heart scan. My doctor was unable to give a good reason for why I should not have a heart scan but a CT angiogram. ("You are too young to have a heart scan"). So the situation here in India is no better.
  Many thanks!
