Risks for coronary disease 2008

31. December 2007 William Davis (27)

According to conventional thinking, there are identifiable risks for coronary disease and heart attack. These risk factors are:

* smoking
* high blood pressure
* high blood cholesterol and excessive saturated fat intake
* diabetes
* being overweight or obese
* physical inactivity

I'd agree with all the factors listed (though I would argue about the importance of high blood cholesterol and saturated fat; they are not as important as commonly made to be.)

Is the list complete?

From the unique perspectives gained in the Track Your Plaque program, I'd offer a significantly different list. Trying to stop or reduce coronary atherosclerotic plaque and heart scan scores makes you a whole lot smarter about what works and what doesn't work.

So, in addition to the risk factors listed above, I would add:

* Small LDL particles--Lots of small LDL particles is MORE important than high LDL.
* High blood pressure with exercise
* Excessive wheat intake and other processed carbohydrates--An issue of explosive importance today. Wheat creates large numbers of small LDL particles, among other adverse effects.
* Vitamin D deficiency--Among the most powerful risks I know of. It belongs at the top of the list.
* Vitamin K2 deficiency
* Low HDL cholesterol
* Blood sugar >100 mg/dl
* High triglycerides--While some argue about whether triglycerides are a risk that behaves independently of patterns like low HDL, they are neglecting the potent force of this risk. Sure, it occurs in tandem with low HDL (usually, though not always), but it is a factor that can leave you with risk even when HDL is raised to healthy levels.
* Lipoprotein(a)--It is eminently, positively crystal clear that lipoprotein(a) is a powerful risk for heart disease. The lack of a profitable treatment keeps it hidden in the shadows.
* Pessimism--Be happy, do better. Be a constantly angry, frustrated, complaining sourpuss and you are more likely to succumb to heart disease, cancer, or other undesirable fate.

These are the risk factors that we address through the Track Your Plaque program, a list that yields a far more powerful and comprehensive approach to control over coronary plaque/atherosclerosis, sufficient to achieve reversal in many (though not in all) instances.

I view the list of conventional risk factors as a "no brainer" list. Sure, smoking is a risk factor. But there are virtually no smokers in the Track Your Plaque program. If you smoke, you clearly don't care enough to engage in a high-intensity prevention program like this.

Saturated fat? Perhaps, but the battlefield of heart disease is riddled with the bodies of those who employed this as their sole strategy and failed catastrophically.

Diabetes, hypertension, and overweight all represent a continuum of risk; the solutions offered in the conventional scheme (i.e., low-fat diet, etc.) make these patterns worse, not better.

The conventional response to heart disease risk is trapped somewhere in 1973 and has not changed in over 30 years. Heart disease continues to be a growth industry for hospitals and the pharmaceutical and medical device industries. The "official" organizations continue to deliver an antiquated, outdated message.

If you want heart disease, follow the American Heart Association diet. If you want established heart disease to get worse, follow the American Heart Association diet. If you want diabetes or, if you already have diabetes or pre-diabetes, if you want it to worsen and develop organ damage (eyes, kidneys, nervous system, etc.), then follow the American Diabetes Association diet. USDA food pyramid? Loosen your belt!

The list of conventional risk factors for heart disease is woefully inadequate. If that is as far as your prevention program takes you, heart disease will not be controlled or prevented. At best, it might be slowed; at worst--and more likely--it might be accelerated.

Food sources of vitamin K2

27. December 2007 William Davis (46)

Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

The ideal source of K2 is natto, the unpalatable, gooey, slimy mass of fermented soybeans that Japanese eat and has been held responsible for substantial decreases in osteoporosis and bone fractures of aging. Natto has an ammonia-like bouquet, in addition to its phlegmy consistency that makes it virtually inedible to anyone but native Japanese.

I say that the conversation on vitamin K2 is emerging because of a number of uncertainties: What form of vitamin K2 is best (so-called MK-4 vs. MK7 vs. MK-9, all of which vary in structure and duration of action in human blood)? What dose is required for bone benefits vs. other benefits outside of bone health? Why would humans have developed a need for a nutrient that is created through fermentation with only small quantities in meats and other non-fermented foods?

Much of the developing research on vit K2 is coming from the laboratories of Drs. Vermeer, Geleijnse, and Schurgers at the University of Maastricht in the Netherlands, along with several laboratories in Japan, the champions of K2.

MK-7 and MK-8,9,10 come from bacterial fermentation, whether in natto, cheese, or in your intestinal tract; MK-4 is naturally synthesized by animals from vitamin K1. While natto is the richest source of the MK-7 form, egg yolks and fermented cheeses are the richest sources of the MK-4 form.

Chicken contains about 8 mcg MK-4 per 3 1/2 oz serving; beef contains about 1 mcg. Egg yolks contain 31 mcg MK-4 per 3 1/2 oz serving (app. 6 raw yolks). Hard cheeses contain about 5 mcg MK-4 per 3 1/2 oz serving, about 70 mcg of MK-8,9; soft cheeses contain about 30% less. Natto contains about 1000 mcg of MK-7, 84 mcg MK-8, and no MK-4 per 3 1/2 oz serving.

Feta cheese

Thanks to the research efforts of the Dutch and Japanese groups, several phenomena surrounding vitamin K2 are clear, even well-established fact:

--Vitamin K2 supplementation (via frequent natto consumption or pharmaceutical doses of K2) substantially improves bone health. While K2 by itself exerts significant bone density/strength increasing properties in dozens of studies, when combined with other bone health-promoting agents (e.g., vitamin D3, prescription drugs like Fosamax and calcitonin), an exaggerated synergy of bone health-promoting effects develop.

--The MK-4 form of vitamin K2 is short-lived, lasting only 3-4 hours in the body. The MK-7 form, in contrast, the form in natto, lasts several days. MK-7 and MK-8-10 are extremely well absorbed, virtually complete.

--Bone health benefits have been shown for both the MK-7 and MK-4 forms.

--Coumadin (warfarin) blocks all forms of vitamin K.

Interestingly, farm-raised meats and eggs do not differ from factory farm-raised foods in K2 content. (But please do not regard this as an endorsement of factory farm foods.)

Another interesting fact: Since mammals synthesize a small quantity of Vit K2 forms from vitamin K1, then eating lots of green vegetables should provide substrate for some quantity of K2 conversion. However, work by Schurgers et al have shown that K1 absorption is poor, no more than 10%, but increases significantly when vegetables are eaten in the presence of oils. (Thus arguing that oils are meant to be part of the human diet. Does your olive oil or oil-based salad dressing represent fulfillment of some subconscious biologic imperative?)

If we believe the data of the Rotterdam Heart Study, then a threshold of 32.7 micrograms of K2 from cheese yields the reduction in cardiovascular events and aortic calcification.

It's all very, very interesting. My prediction is that abnormal (pathologic) calcium deposition will prove to be a basic process that parallels atherosclerotic plaque growth, and that manipulation of phenomena that impact on calcium depostion also impact on atherosclerotic plaque growth. Vitamins D3 and K2 provide potential potent means of at least partially normalizing these processes.

As the data matures, I am going to enjoy my gouda, Emmenthaler, Gruyere, and feta cheeses, along with a few egg yolks. I'm going to be certain to include healthy oils like olive and canola with my vegetables.

Track Your Plaque: Naughty or nice?

24. December 2007 William Davis (6)

Among the many wonderful surprises we've had at Track Your Plaque this holiday season was a letter from Santa Claus himself!

It seems that Santa, like the rest of us, has been busy surfing the web for useful health information the last few months. He was struck with this curious discussion we've been having about "wheat belly" and all the unhealthy consequences of wheat products in our diet.

He writes:

"I wouldn't have believed it myself, except that my waist size has grown four inches in as many years. Sure, I'm known for my healthy girth, but now even Mrs. Claus calls me fat!

"I was open to new ideas when I came across this crazy discussion about eliminating wheat from your diet. So I said, "What have I got to lose?" Well, four weeks later and 12 lbs lighter, I'm convinced. Now comes the tough part: I've got to deliver all the toys and resist all those cookies the children put out for me. I wonder if wheat makes reindeer fat, too?

"Anyway, thanks to your program I'm back to my old weight again. Doc says my blood sugar and blood pressure are also back down to normal. Thanks, Track Your Plaque! (You'll find something extra special under the tree this year.)"

And so it goes. I'm tempted to put Santa's testimonial on our homepage, but I think that may be tooting our own horn a bit too much.

Have a wonderful holiday!

Vitamin D: Treatment for metabolic syndrome?

21. December 2007 William Davis (44)

Metabolic syndrome is that increasingly common collection of low HDL cholesterol, high triglycerides, high blood sugar, and high pressure that now afflicts nearly 1 in 4 adults, rapidly gaining ground to 1 in 3. Beyond these surface factors, metabolic syndrome also creates small LDL particles, VLDL, intermediate-density lipoproteins (IDL), increased imperceptible inflammation measured as higher c-reactive protein, and greater blood clotting tendencies. Metabolic syndrome is usually, though not always, associated with a big tummy ("beer belly," though I call it "wheat belly").

In short, metabolic syndrome creates a metabolic mess that leads to dramatic increases in heart disease, vascular disease and stroke, and cancer. The medical community has been paying increasingly greater attention to this condition because of its booming prevalence and because of the big bucks invested in "education" by the manufacturers of the diabetes and pre-diabetes drugs, particularly makers of Actos and Avandia.

But here's a curious observation:

Replacement of vitamin D to healthy levels (we aim for 50-60 ng/ml, or 125-150 nmol/l) yields:

--Higher HDL
--Lower triglycerides
--Lower blood sugar
--Reduced c-reactive protein
--Reduced blood pressure
--Reduced small LDL
--Enhanced sensitivity to insulin

(Whether blood clotting and effects on IDL should be added to this list is uncertain.)

It's obvious: Vitamin D is proving to be a very important and powerful corrective influence on many of the facets of the metabolic syndrome. In fact, I would go as far as saying that, side by side, vitamin D yields nearly the same effect as prescription drugs Actos and Avandia--without the extravagant cost (nearly $200 per month), leg swelling, congestive heart failure and heightened heart attack risk (with Avandia), and average 8 lb weight gain. Of course, vitamin D also provides benefits beyond metabolic syndrome like facilitation of coronary plaque regression, increased bone density, reduced arthritis, and reduced risk of several cancers.

You'd think that agencies like the American Diabetes Association (ADA) would be all over vitamin D like white on rice. Yet they remain curiously quiet about the entire issue. (That should come as no surprise to anyone familiar with the behavior and politics of this organization, the same outfit that has widely propagated the ADA diet, a program that accelerates diabetes and its complications. In my view, the ADA is an embarassment.)

For a really great story and video on vitamin D that includes a terrific interview with vitamin D guru and Track Your Plaque friend, California psychiatrist Dr. John Cannell, go to What's the Real Story on Vitamin D?. While the video will yield little new to readers of The Heart Scan Blog or Track Your Plaque members, it just feels really good to see a well-made, high-class video production echoing many of the things we've been talking about these past two years.

Appetite stimulants

20. December 2007 William Davis (17)

Ever have days when you just can't seem to get enough to eat, your stomach gnawing just a hour after a meal? We all get them, some more than others. Other days, you can be content with a few simple foods and hunger is subdued, temptation easy to control.

Why such contrasts on different days?

A major part of the reason can be the presence of appetite stimulants, factors that trigger appetite beyond rational control. The list of common appetite stimulants includes:

--Sleep deprivation--A very important factor. Lack of sleep drives tremendous appetite, and often for the wrong foods (processed carbohydrates). I personally have experienced my most shamefully indulgent days when sleep-deprived. The solution is obvious: Sleep. Another factor that is based purely on personal observation is that of waking mid-phase. In other words, waking up while you're still enjoying the deeper phases of sleep (e.g., phase 3,4, or REM). This can oddly disrupt your day and your impulse control. I usually try and time sleep to increments of 90 minutes to coincide with the average duration of the full cycle of sleep. For example, 7 1/2 hours is better than 8 hours, since the extra half hour puts your square into a deeper sleep cycle.

--Excessive caffeine--Caffeine stimulates stomach acid. This triggers the impulse to eat . . . and eat and eat.

Image courtesy Wikipedia

--Aspirin and other anti-inflammatory agents--If you take aspirin (as many of our Track Your Plaquers do), then beware of the gastritis that can develop. Like excessive caffeine, it also triggers the impulse to eat, likely a protective mechanism, since food sops up excess acid. I ask patients to take periodic breaks from aspirin, e.g., a week off every two or three months, to allow the stomach to heal. Alternatively, an occasional dose of acid-suppressing medication is a safe practice, e.g., Pepcid AC 10-20 mg; Prilosec 10-20 mg.

--Wheat-containing foods--Followers of The Heart Scan Blog know my feelings on this. Wheat is a potent appetite stimulant: Eat something containing wheat like a pretzel or whole wheat bagel, and you want more. You may want more immediately, or a little later when your blood sugar plunges after the wheat-driven insulin surge. Solution: Dump the wheat, one of the most unhealthy food groups around.

--Alcohol--Though perhaps not a direct appetite-stimulating effect, the loss of impulse-control with alcoholic drinks can lead to overindulgence, often in the worst foods. Just beware.

--Hanging around with heavy people. Remember peer pressure? It can be subliminal. People with poor eating habits provide the silent message that it's okay to yield to impulse, overeat, overindulge, and choose the wrong foods.

--Stress--Whether through cortisol stimulation or other means, stress triggers appetite in some people. If you experience this and must give in, reach for raw nuts or nuts, rather than wheat snacks or chips. The effect will be minimal, perhaps even beneficial, rather than the bloating, appetite-stimulating, fattening effect of crackers, chips, or pretzels. This may be the same phenomenon as taking prescription steroids like prednisone.

--Short dark days, long nights--In other words, winter. Though just an anecdotal observation, I am convinced that vitamin D supplementation is an effective antidote to this effect. The short, dark days just don't bother you as much, perhaps not at all, and there's no impulse for comfort foods.

How about appetite suppressants? In this list I would include 1) raw nuts--especially almonds, walnuts, pecans, and pistachios, the sort with a fibrous covering and rich in monounsaturates, 2) other sources of plentiful healthy oils, e.g, use more olive oil in your salad or add it to hummus for your veggie dip, 3) space-occupying fibers such as glucomannan, inulin (such as in Fiber Choice), and psyllium seed products. Counteracting the above appetite stimulants like sleep deprivation is, of course, important.

The coming wheat frenzy, otherwise known as the holidays, is an especially important time to be aware of these effects. Eat, drink, and be merry--but with rational impulse control not driven by subconscious appetite stimulants.

"Heart scans are experimental"

18. December 2007 William Davis (25)

Let me warn you: This is a rant.

It is prompted by a 44-year old woman. She has a very serious lipoprotein disorder. Her family experiences heart attacks in their 40s and 50s. I asked for a heart scan. Her insurance companied denied it.

This is nothing new: heart scans, like mammograms, have not enjoyed reimbursement from most insurers despite the wealth of data and growing acceptance of this "mammogram" of the heart.

However, 10 minutes on the phone, and the "physician" (what well-meaning physician can do this kind of work for an insurance company is beyond me) advised me that, while CT heart scans for coronary calcium scoring are not covered, CT coronary angiograms are.

Now, I've been witnessing this trend ever since the big players in CT got involved in the game, namely Philips, Siemens, Toshiba, and GE. These are enormous companies with hundreds of billions of dollars in combined annual revenues. They, along with the lobbying power of cardiology organizations like the American College of Cardiology, have gotten behind CT coronary angiograms. This is most likely the explanation of why CT coronary angiograms have rather handily obtaining insurance reimbursement. Interestingly, the insurance company I was speaking to is known (notorious?) for very poor reimbursement practices.

A CT heart scan, when properly used, generates little revenue, a few hundred dollars to a scan center, barely enough to pay for a device that costs up to $2 million. However, CT coronary angiograms, in contrast, yield around $2000 per test. More importantly, they yield downstream revenues, since CT angiograms are performed as preludes to conventional heart catheterizations, angioplasty, stents, bypass surgery, etc. Now we're talking tens or hundreds of thousands of dollars revenue per test.

What puzzles me is that much of that increased cost comes out of the insurance company. Why would they support such tests if it exposes them to more costs? I'm not certain. It could be the greater pressures exerted by the big CT companies and powerful physician organizations. I seriously doubt that the insurance companies truly believe that heart scans for coronary calcium scoring are "experimental" while CT coronary angiograms are "proven." If all we did was compare the number of clinical studies that validate both tests, we'd find that the number of studies validating heart scans eclipses that of coronary angiograms several fold. Experimental? Hardly.

The smell of money by physicians eager to jump on the bandwagon of a new revenue-producing procedure is probably enough to have them lobby insurers successfully. In contrast, plain old heart scans just never garnered the kind of vigorous and vocal support, since nobody gets rich off of them.

If CT coronary angiograms are sufficiently revenue producing that my colleagues and the CT scanner manufacturers have managed to successfully lobby the health insurers, even one as financially "tight" as the one I spoke to today, well then I take that as testimony that money drives testing, as it does the behavior of hospitals, many of my colleagues, and can even force the hand of insurers.

When meat is not just meat

18. December 2007 William Davis (7)

The edgy nutrition advocate, Mike Adams, over at NewsTarget.com came up with this scary photo tour of a processed meat product from Oscar Mayer: Mystery Meat Macrophotography: A NewsTarget PhotoTour by Mike Adams

Along with increasingly close-up photographs of this meat-product, Adams lists the ingredients in Oscar Mayer's Cotto Salami:

Beef hearts
Pork
Water
Corn syrup
Beef

Contains less than 2% of:
Salt
Sodium lactate
Flavor
Sodium phosphates
Sodium diacetate
Sodium erythorbate
Dextrose
Sodium nitrite
Soy lecithin
Potassium phosphate
Potassium chloride
Sugar

As I reconsider the role of saturated fat in diet, given the startlingly insightful discussion by Gary Taubes of Good Calories, Bad Calories, I am reminded that not all meat is meat, not all saturated fat sources are equal.

I am concerned in particular about sodium nitrite content, a color-fixer added to cured meats that caused a stir in the 1970s when data suggesting a carcinogenic effect surfaced. The public's effort to remove sodium nitrite from the food supply was vigorously opposed by the meat council and it remains in cured meats like sausage, hot dogs, and processed meats like Cotto Salami. A 2006 meta-analysis (combined analysis of studies) of 63 studies did indeed suggest that sodium nitrite was related to increased risk of gastric cancer. This argument is plausible from animal models of cancer risk, as 40 animal models have likewise suggested the same carcinogenic association.

Also, fructose? This is most likely added for sweetness. Recall that fructose heightens appetite and raises triglycerides substantially.

I personally have a natural aversion to meat. I don't like the taste, the look, smell, and the thought of what the animal went through to make it to the supermarket. But, considered from the cold, carnivorous viewpoint of the question, "Is meat okay to eat?", among the issues to consider is whether the meat has been cured or processed, and does that process include addition of sodium nitrite.

Cotto Salami and similar products are not, of course, what carnivorous humans in the wild ate. This is a processed, modified product created from factory farm animals raised in cramped conditions and fed corn and other cheap, available foods. It is not created from free-ranging animals wandering their pastures Cureality | Real People Seeking Real Cures

What Mr. Clinton did NOT do

12. February 2010 William Davis (36)

You've likely already heard that former President Bill Clinton underwent a heart catheterization today during which one of the bypass grafts to his coronary arteries was found to be occluded. The original coronary artery was therefore stented.

Dr. Alan Schwartz, Mr. Clinton's cardiologist, announced to the gathered press that Mr. Clinton had followed a good diet, had adopted a regular exercise program, but that his condition is a "chronic disease" like hypertension that is not cured by these efforts.

Needing a stent just 6 years after four bypass grafts are inserted is awfully soon. I would propose that it has less to do with having a "chronic disease" and more to do with all the things that Mr. Clinton likely is NOT doing. (In addition to all the other things that Mr. Clinton did not do.) In other words, in the Track Your Plaque world, procedures are a rarity, heart attacks virtually unheard of. I would wager that Mr. Clinton has been doing none of the following:

--Taking fish oil. Or, if his doctor was "advanced" enough to have advised him to take fish oil, not taking enough.
--Vitamin D--Followers of the Heart Scan Blog already know that vitamin D is the most incredible health find of the last 50 years, including its effects on reducing heart disease risk. Unless Mr. Clinton runs naked in a tropical sun, he is vitamin D deficient. A typical dose for a man his size is 8000 units per day (gelcap only!).
--Eating a true heart healthy diet. I'll bet Mr. Clinton's doctor, trying to do the "right" thing, follows the prudent course of advising a "balanced diet" that is low in fat--you know, the diet that causes heart disease. Judging by Mr. Clinton's body shape (central body fat), it is a virtual certainty that he conceals a severe small LDL pattern, the sort that is worsened by grains, improved with their elimination.
--Making sure that hidden causes are addressed--In addition to the "hidden" small LDL, lipoprotein(a) is another biggie. Lp(a) tends to be the province of people with greater than average intelligence. I believe Mr. Clinton qualifies in this regard. I would not be at all surprised if Mr. Clinton conceals a substantial lipoprotein(a) pattern, worsened in the presence of small LDL.
--Controlling after-meal blood sugars--Postprandial (after-eating) blood sugars are a major trigger for atherosclerotic plaque growth. There are easy-to-follow methods to blunt the after-meal rise of blood sugar. (This will be the subject of an in-depth upcoming Track Your Plaque Special Report.)
--Thyroid normalization--It might be as simple as taking iodine; it might involve a little more effort, such as supplemental T3. Regardless, thyroid normalization is an easy means to substantially reduce coronary risk and slow or stop coronary plaque growth.

It's not that tough to take a few steps to avoid bypass surgery in the first place. Or, if you've already had a procedure, a few additional steps (of the sort your doctor will likely not tell you about) and you can make your first bypass your only bypass.

Magnesium and arrhythmia

11. February 2010 William Davis (35)

Because magnesium is removed during municipal water treatment and is absent from most bottled water, deficiency of this crucial mineral is a growing problem.

Magnesium deficiency can manifest itself in a wide variety of ways, from muscle cramps (usually calves, toes, and fingers), erratic blood sugars, higher blood pressure, to heart rhythm problems. The abnormal heart rhythms that can arise due to magnesium deficiency include premature atrial contractions, premature ventricular contractions, multifocal atrial tachycardia, atrial fibrillation, and even ventricular tachycardia, fibrillation, and Torsade de Pointes (all potentially fatal). Magnesium is important!

Magnesium supplementation is therefore necessary for just about everybody to maintain normal tissue levels. (The exception is people with kidney disorders, who should not take magnesium without supervision, since they retain magnesium.)

Here is a Heart Scan Blog reader's dramatic rhythm-correcting response to magnesium supplementation:

Dr. Davis,

A few months ago, I contacted you inquiring if you had written any articles on arrhythmia. You were generous enough to answer and guide me to an LEF article you'd written in which you stressed fish oil and magnesium. I had been suffering with bad PVCs [premature ventricular contractions] for over 20 years, and they had gotten so bad recently that I was told my next options were ablation or pacemaker!

I was already on fish oil and had not seen any difference, and so I researched the magnesium you suggested more thoroughly and found a huge body of studies supportng its effect on arrhythmia. I also read many posts on heart forums with people having success with it. After getting advice from various bloggers, I tried magnesium taurate in the morning and Natural Calm (an ionized form of mag citrate) in the afternoon and evening. Within three days the PVCs were quite diminished and by 2 weeks totally gone! As long as I keep taking it, they never return---not even one irregular blip---even when I drink strong coffee! The magnesium also cleared up my restless leg syndrome, my eye twitching, and insomnia. (Apparently, I was the poster-girl for magnesium deficiency.)

I am so angry that after all these years of suffering, trying various medications, and seeing at least 4 different cardiologists that NOT ONE ever even mentioned trying magnesium. The generosity of the few minutes you took to answer my email and steer me in a helpful direction brought me total relief.

Thank you SO MUCH!

Warmly,
Catherine C.

Should you exercise? Lengthen you workout? Push the plate away, deny yourself seconds, use a smaller plate?

Of all the weight loss strategies I've tried in patients, there's only one that stands out as a means of obtaining immediate--meaning within 3 days--weight reduction.

Wheat elimination.

Omega-3 Index: 10% or greater?

9. February 2010 William Davis (19)

We've previously considered the question:

What is an ideal level of omega-3 fatty acids in the blood?

Recall that omega-3 levels in red blood cells (RBCs), a measure called the "omega-3 index," have been associated with risk for sudden cardiac death:

In a recent analysis, 265 people experiencing sudden death during a heart attack (ventricular fibrillation, successfully resuscitated) showed an omega-3 index of 4.88%, while 185 people not experiencing sudden death during a heart attack showed an omega-3 index of 6.08%.

We have more ambitious goals than just avoiding sudden death, of course! How about the omega-3 index associated with reduced risk for heart attack? A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks, suggesting that even higher levels are necessary to prevent non-fatal events.

Most recently, another study comparing 50 people after heart attack with 50 controls showed that people with heart attack had an omega-3 index of 9.57% vs 11.81% in controls--even higher. (This study was in a Korean population with higher fish consumption. There was also a powerful contribution to risk from trans fat RBC levels.) The investigators concluded: "The area under the receiver operating characteristic curve of fatty acid profiles was larger than that for traditional risk factors, suggesting that fatty acid profiles make a higher contribution to the discrimination of MI cases from controls compared with modified Framingham risk factors."

The data suggest that, while an omega-3 index of 7.3% is associated with reduced risk for sudden cardiac death, a higher level of 10% or greater is associated with less risk for heart attack. Surprisingly, fish consumption and fish oil intake account for only 47% of the variation in omega-3 index.

I believe the emerging data are becoming increasingly clear: If you desire maximal control over heart health, know your omega-3 index and keep it 10% or higher.

Let's soak 'em with fish oil

8. February 2010 William Davis (12)

If you don't think that charging drug prices for fish oil is wrong, take a look at a letter from an angry Heart Scan Blog reader:

Hello Dr. Davis,

My 44 year old brother had an MI [myocardial infarction, or heart attack] in June. He got pushed around due to "bad government insurance," a state-run program for the "uninsured": government pays 1/3, job pays 1/3, and individual pays 1/3.

What they didn't tell him is that there is no major medical coverage and little to no prescription coverage. We fought for 4 months to get him open heart surgery that the insurance was not going to pay for.

Now, with no assistance, terrible insurance, and no disability he has little to no income. He is a heavy equipment mechanic and is trying to be the "good American"-- take care of his bills, not file bankruptcy, etc.

Anyway, the doctors never seem to pay attention to what they prescribe. Lipitor was not working for him, due to side effects. Now they want to give him Zetia and Lovaza....Zetia at $114, and Lovoza is $169.85! Wow! For dead fish???? I think this is a little fishy! I looked up Lovaza, gee how nice, they will give you a $20 coupon....

Forget it, he can't afford this stuff. So I am enrolling in the Zetia program for him. And trying to get him OTC [over-the-counter] fish oil. The most prevalent fish oil around here (that I take myself is) Omega 3 Fish Oil that has EPA 410mg, DHA 274.

Thanks for your blog. It made me feel better that I wasn't the only one outraged by this stuff. I 've been a nurse for 20 years and it just never seems to get better. Thank you for your wisdom.

Sincerely JP, Tennessee

Had this reader not been aware that her brother could take fish oil as a nutritional supplement, he likely would have been denied the benefit of omega-3 fatty acids in slashing the risk for recurrent cardiovascular events. You and I can buy wonderfully safe and effective fish oil as a nutritional supplement, but there won't be a sexy drug representative to sell it, nor an expensive dinner and payment for a trip to Orlando to hear about it.

Heart scan gone wrong

Those of you reading the Heart Scan Blog, I hope, have come to appreciate the power in measuring atherosclerotic plaque, the stuff of coronary artery disease, and not relying on indirect potential "risk factors," especially the fictitious LDL cholesterol.

However, like all things, even a great thing like heart scans can be misused. Here's a story of how a heart scan should NOT be used, submitted by a reader.

Dr. Davis,

First of all, let me start out by commending you on all of the work you are doing with your website, blogs, etc. You are truly a breath of fresh air at a time when conventional medicine is no longer making any sense. In the last 3 years or so, I have spent a lot of time using the internet to try and find answers . . . and just about every time, when I find things that make "sense," it coincides which the recommendations you provide. Thank You!!

I am 56 years old, and roughly 5 years ago I bought your book, Track Your Plaque, primarily because I had asked my then Internal Medicine physician about why we weren't more "proactive" about determining the state of our cardiovascular health...since the means to do so existed (scans). He was trying to get me to go on a statin because my cholesterol #'s were a little high and at the time I smoked. Other than that, I was in perfectly good health with no side effects or issues. The following year at my annual physical, we again discussed this and he gave me a few options and I ended up having a calcium score done, which showed some blockage, but again, I never had any pains, sweats, or any other symptoms whatsoever, and I am a very active former athlete. This is when I bought your book to try and set a course of plan that wouldn't just include pharmaceuticals.

At the same time, my father was in his last months of life dealing with prostate cancer and the multiple radiation and chemo treatments, so I was making many trips from my home to be with him . . . a 4 hour drive, and very disruptive to family, as I still have 3 kids at home. At what I thought was going to be my last visit with him, I stopped at the cemetery he had planned on being buried to confirm details and such and then started home.

As I was driving, a symptom hit me which I was unfamiliar with (pretty sure it was an anxiety attack now) and I stopped at a friend's house in Chicago, as I didn't want this to be a heart attack while I was driving. This is when I began thinking about the heart scan and the blockage, and ended up driving back later that night and went right to the ER....not because I had any chest pains, but thought it best to be checked out because I did not want to go before my dad did. I ended up staying the night. In the morning the cardiologist PA [physician's assistant] came in with a copy of my calcium scoring and said it was best to have a heart cath...which I was in total agreement with since it would definitively tell me the current condition of my coronary vessels. As I was getting ready to be wheeled into the cath lab, they approached me with a form that would allow them to treat (stent). This is where I became very uncomfortable, in that I had never even met the cardiologist . . . and I didn't like this. No one ever had asked if I was experiencing pains or anything else . . . but I buckled and signed the form.

Before you knew it, I was awake watching my heart being cathed and the cardiologist angry because they did not have all the right sizes of stents, so he had to use a couple extra and I ended up w/5 total . . . and my life changed forever! In looking back, I can't necessarily argue the need for intervention, but in hindsight, it would have been nice to have tried an alternative method of reversing my plaque, especially since I had never experienced any symptoms and didn't appear to be in any imminent danger.

Upon release from the hospital I was put on a cocktail of drugs that typically follow and I then began to search and research. No one talked to me about lifestyle changes other that smoking....but nothing on diet or other means of cholesterol control, etc....in fact, when I had to pick out my meals in the hospital, they wouldn't let me have cheese....but the rice crispy treat was fine....how stupid! They originally told me the Plavix had to last 6 months....and then 12....and then 2 years....I stayed on it for 1-1/2 years and it was the only thing other than a baby aspirin. I went to another cardiologist out of town and he wanted me back on 5 or 6 medications and said that now I had the stents....I would have to be on these for life.....and he was the expert that talked at several main conferences.....my last trip to him.

Now, fast forward to about 6 months ago: I was participating in a father-son soccer scrimmage and was playing goalie. It was wet out and I couldn't catch very well. So being the competitive person I am, I resorted to using my chest on several of the saves and also took a direct blow to my eye ( I wear glasses) and the eye started swelling up pretty good. We then finished and went inside to have pizza and everyone was concerned about my eye. About 30 minutes later I excused myself as i felt some pretty significant sweats and subsequently a pretty severe pain directly in the middle of my chest....I was having a heart attack! Called 911 and went to hospital (2-1/2 years since original stents) and my local cardiologist removed the blockage that was at the anterior portion of my 1st stent causing the blockage. The huge disappointment to me is that I had taken many steps to improve my overall health. But now that I have foreign bodies in my vessels, the chance of further clotting is something that i will most likely always have to live with.

BU, Michigan

This is an example of how heart scans should NOT be used. They should NEVER be used to justify a procedure, no matter how high the score or where the plaque is located. The "need" for procedures is determined by symptoms (BU's symptoms were hardly representative of heart disease), blood findings, EKG, stress testing, and perhaps CT coronary angiography. "Need" for procedures can never be justified simply on the basis of the presence of plaque by a heart scan calcium score.

Unnecessary procedures like the one BU underwent are not entirely benign, as his experience at the soccer game demonstrated.

Heart scans are truly helpful things. But, like many good things, they are subject to misuse in the hands of the uncaring or greedy.

Blood sugar: Fasting vs. postprandial

5. February 2010 William Davis (23)

Peter's fasting blood glucose: 89 mg/dl--perfect.

After one whole wheat bagel, apple, black coffee: 157 mg/dl--diabetic-range.

How common is this: Normal fasting blood sugar with diabetic range postprandial (after-eating) blood sugar?

It is shockingly common.

The endocrinologists have known this for some years, since a number of studies using oral glucose tolerance testing (OGTT) have demonstrated that fasting glucose is not a good method of screening people for diabetes or pre-diabetes, nor does it predict the magnitude of postprandial glucose. (In an OGTT, you usually drink 75 grams of glucose as a cola drink, followed by blood sugar checks. The conventional cut off for "impaired glucose tolerance" is 140-200 mg/dl; diabetes is 200 mg/dl or greater.) People with glucose levels during OGTT as high as 200 mg/dl may have normal fasting values below 100 mg/dl.

High postprandial glucose values are a coronary risk factor. While conventional guidelines say that a postprandial glucose (i.e., during OGTT) of 140 mg/dl or greater is a concern, coronary risk starts well below this. Risk is increased approximately 50% at 126 mg/dl. Risk may begin with postprandial glucoses as low as 100 mg/dl.

For this reason, postprandial (not OGTT) glucose checks are becoming an integral part of the Track Your Plaque program. We encourage postprandial blood glucose checks, followed by efforts to reduce postprandial glucose if they are high. More on this in future.

Diabetes from fruit

2. February 2010 William Davis (38)

Mitch sat in my office, looking much the same as he had on prior visits.

At 5 ft 7 inches, he weighed a comfortable 159 lb, though he did have a small visible "paunch" above his beltline.

I had been seeing Mitch for his heart scan score of 1157 caused by low HDL of 38 mg/dl, severe small LDL (87% of total LDL), and lipoprotein (a).

Part of Mitch's therapeutic program was elimination of wheat, cornstarch, and sugars, the three most flagrant triggers of small LDL particles, and weighing his diet in favor of oils and fats to reduce Lp(a). However, Mitch somehow failed to follow our restriction on fruit, which we limit to no more than two 4 oz servings per day, preferably berries. He thought we said "Eat all the fruit you want." And so he did.

Mitch had a banana, orange, and blueberries for breakfast. For lunch, along with some tuna or soup, he'd typically have half a melon, a pear, and red grapes. For snacks, he'd have an apple or nectarine. After dinner, it wasn't unusual for Mitch to have another piece of fruit for dessert.

Up until Mitch's last visit, he'd had blood glucose levels of 100-112 mg/dl, above normal and reflecting mild insulin resistance and pre-diabetes. Today, on his unlimited fruit diet, his blood sugar: 166 mg/dl--well into diabetes territory.

I helped Mitch understand the principles of our diet better and advised him to reduce his fruit intake to no more than the 2 small servings per day, as well as sticking to our "no wheat, no cornstarch, no sugar" principles.

While fruit is certainly better than, say, a half-cup of gummy bears (84.06 g carbohydrates, 50.12 g sugars), fruit is unavoidably high in carbohydrates and sugars.

Take a look at the carbohydrate content of some common fruits:

Apple, 1 medium (2-3/4" dia)
19.06 g carbohydrate (14.34 g sugar)

Banana, 1 medium (7" to 7-7/8" long)
26.95 g carbohydrate (14.43 g sugar)

Grapes, 1 cup
27.33 g carbohydrate (23.37 g sugar)

Pear, 1 medium
25.66 g carbohydrate (16.27 g sugar)

Source: USDA Food and Nutrient Database

Fruit has many healthy components, of course, such as fiber, flavonoids, and vitamin C. But it also comes with plenty of sugar. This is especially true of modern fruit, the sort that has been cultivated, hybridized, fertilized, gassed, etc. for size and sugar content.

When you hear such conventional advice like "eat plenty of fruits and vegetables," you should hear instead: "eat plenty of vegetables. Eat a small quantity of fruit."

The sniff test

It is well established that omega-3 fatty acids from fish oil are free of mercury, PCBs, furans, and other pesticide residues. Several independent analyses have all agreed: little to none are contained in fish oil. In the Consumer Lab series of assessments, for example, no fish oil supplement failed because of any heavy metal or pesticide residue.

However, oxidative byproducts are a problem. Just as fish that sits on the store shelf or your refrigerator too long starts to smell "fishy," so will fish oil. When fish or fish oil becomes rancid, smelling like rotten fish at its worst, it means that
