Wheat-free and still fat

Readers of The Heart Scan Blog know that I preach a diet that contains foods with low glycemic index to control weight, raise HDL, and reduce triglycerides, blood sugar, and small LDL.

A crucial aspect of a low glycemic index approach is to sharply reduce, preferably eliminate, wheat products.

I pick on wheat specifically because it has come to dominate the American diet. Look at the shelves in the supermarket: aisle after aisle of processed wheat products. The bread shelves alone in some of the grocery stores in my neighborhood are 40 feet long, six shelves high. There's also breakfast cereals, granola products, cookies, cakes, baking products, pretzels, crackers, pasta, and on and on.

Wheat products like these are tasty and they're addicting--literally. Test animals given processed wheat will eat more and gain more weight. Wheat fails to trigger satiety. So laboratory mice--and you and I--eat and eat, because eating wheat stimulates appetite, creates a hunger for more wheat, and a vicious cycle ensues. Eliminating wheat, on the other hand, results in dramatic drop in appetite, substantial weight loss, followed by correction of the metabolic disruptions it created.


A quick Google search for "gluten-free" turns up a startling array of wheat-free, gluten-free, yet high glycemic index products. The breakfast cereal pictured, for instance, can do as much damage as most wheat containing products--though it won't cause gluten enteropathy (also known as "celiac disease").




The product shown contains:

Brown rice flakes, rice bran, evaporated cane juice, brown rice syrup, raisins, cinnamon, gum arabic, vanilla, molasses, ground flaxseed, rosemary extract.

A 1/2-cup serving contains:
Total Carbohydrate 31g
Dietary Fiber 5g
Sugars 8g


And I'll bet that most people eat a lot more than a half-cup serving.

But you and I are not laboratory mice. If deprived of wheat, many people will then seek out processed rice products (rice cakes, Rice Krispies), processed cornstarch or cornmeal products (tacos, cornbread, many processed foods using these products for texture or thickness), or other products labeled "gluten-free."

Going wheat-free for our purposes is not about avoiding the gluten in wheat. It is about seizing control of appetite, eliminating a food that disrupts insulin responses, reduces HDL, raises triglycerides, and creates small LDL particles. But this applies to processed corn, rice, and other high glycemic index foods, as well.

So, occasionally, someone will declare, "I've eliminated wheat! Now I only eat rice, corn, and I've discovered all the gluten-free alternatives!"

Unfortunately, they've traded one evil for another. So it's not just about wheat. It's really about reducing or minimizing foods that mess up metabolic responses and lead to coronary plaque growth. Wheat is the biggest culprit and so I focus on it. However, you could easily transfer far less popular rice and corn products into center stage and allow them to wreak all the health damage of wheat.

Going wheat-free for our atherosclerotic plaque-control purposes is not the same as going gluten-free. So be careful of the distinction.

Heart disease is reversible

In a previous post, Take this survey: I double-dare you, I posed a challenge:

Ask your doctor: Is heart disease reversible? Their answer:

1) No. Heart disease is definitely not reversible.

2) Yes, in rare instances, like lightning striking twice.

3) Yes, of course it is! Let's talk about how to do it!

I predicted that few readers of this blog would respond. I also predicted that the few who did would respond with the first answer, Heart disease is definitely not reversible. After all, in nearly all medical practices, the only parameters routinely followed to track risk for heart disease are LDL cholesterol and blood pressure. A measure of the disease itself (i.e., coronary atherosclerotic plaque) is not followed. So how can your doctor actually tell whether heart disease is reversed or not? When I engage in this conversation with colleagues, it goes no farther than rolled eyes or a snort. In my experience, talking about reversal of heart disease is a wasted effort.

To my great surprise, this simple survey received a total of 177 responses. Even more surprising, 122 (69%) of respondents chose number 3, claiming that their doctor said that heart disease is reversible.

Overall results:

1--31 responses (17.5%)

2--24 responses (13.5%)

3--122 responses (69%)


Now wait a minute: Where is the disconnect? Why are doctors saying that heart disease is reversible, yet not following this concept in practice? Contrary to the survey results, I have yet to meet a patient who said their doctor was trying to reverse their heart disease. Of course, this may be a skewed population, but I find it hard to believe that the prevailing view is that heart disease is reversible.

Anyway, this simple survey cannot settle the why or how, nor can it suggest just how prevalent this opinion is.

I am encouraged by these results. If true, it means that the message that heart disease is a reversible process is spreading. It may be make-believe heart disease reversal as preached by Dr. Dean Ornish or claimed by statin drug manufacturers. It may be the hocus-pocus of practices like chelation, or scams like nattokinase. But perhaps the seed of this notion has been planted in the minds of the medical community.

I'd be interested in hearing from the respondents who reported that their doctor said heart disease is reversible. How exactly are they going about achieving reversal?

Looking for health in all the wrong places

The American public now has unprecedented freedom to explore new directions in health.

Never before have we had the enormous resources now available to add to our health experience: nutritional supplements, endless books on health and diet, the internet, online discussion groups, insurance products to permit spending on self-directed health services like medical savings accounts and flex-spending. The Track Your Plaque program is just one facet of this emerging and exciting area of self-empowerment in health. Compare what you can achieve with such a program with the situation of just 25 years ago, when the most you might get to reduce your risk for heart disease was to take the (largely ineffective) drug cholestyramine, probucol, and a low-cholesterol, low-fat diet.

Unfortunately, it also means that people have unrestrained potential to be tripped up, to be misled down some dead end of health that fails to accomplish desired goals, maybe even dangerous. The more freedom we have, the greater the choices, the more room we have to screw up.

Among the unproductive strategies I've witnessed recently:

--Nattokinase--The staying power of this scam continues to shock me. There is no rational basis for its use. A woman today declared that she would like to stop the warfarin that she was taking to prevent stroke from atrial fibrillation by taking nattokinase. This would be a mistake that could cost her a major and disabling, even fatal, stroke. Though warfarin is far from perfect, it at least achieves its goal of reducing stroke risk. Nattokinase does not. Nattokinase does nothing but make money for the people who sell it.

--Poly-nutritional supplements. You've heard of polypharmacy, the phenomenon of taking numerous medications with overlapping effects and side-effects, usually because of multiple doctors, each prescribing drugs without knowledge or interest in what colleagues are prescribing. I'm seeing the same phenomenon with supplements: 20,30, or more supplements per day, all in the hopes of heightening health. A focused few supplements is, in my view, superior to a shotgun approach of trying to improve health by taking hawthorne, silymarin, chrysin, calcium, Chinese herbs, and 25 other supplements.

--Chelation--Based on the notion that heavy metal toxicity causes heart disease; removal of heavy metals cures it. I've read some of the books on chelation, in addition to the slim scientific data, to decide whether there was anything to it. In my view, it is a complete and utter scam. It does make money for its practitioners, however. That's not to say that heavy-metal chelation doesn't have a role in health--it does. But it serves no purpose in coronary disease prevention and control.

--Colonic purges--Achieved by a number of routes, some oral, others via enema. Promotions for purging are often accompanied by a pile of scum that apparently lined somebody's intestinal tract. Purges purportedly, well, purge it from the intestine. This is also plain nonsense. There is no such toxic scum lining anybody's intestinal tract. However, if calorie restriction or a fast results inadvertently from the effort, perhaps some good comes from it.

--Statin drug alternatives--The unprecedented $27 billion dollar a year success of the statin drug industry, accompanied by the enormous marketing push by their manufacturers, has spawned an entire industry of statin alternatives. They range from red yeast rice, to guggulipid, to various concoctions of sterol esters, Chinese herbs, chitosan, and a variety of others. Some actually do reduce cholesterol a few points. Preparations like red yeast rice even pose a side-effect profile not too different from the prescription statin agents. Unfortunately, even among those agents that work, the effects tend to be small to trivial. While I am no lover of statin drugs nor the statin drug industry, I find these preparations to be anemic imitators. You'd be better off with raw nuts and ground flaxseed than wasting your money on these cheap imitations.

--Worries about liver toxicity--A day doesn't go by that I don't have at least several questions about suffering toxic liver effects from niacin, vitamin D, statin drugs, etc. I have treated thousands of patients for heart disease in its various stages and forms and have used many different strategies. How many times have I seen serious liver toxicity? A handful of times and usually from either mis-use of the agent or drug, or in a person with several other coexisting diseases. (Other serious health conditions, like kidney failure, raise the toxicity of drugs and supplements.) Liver toxicity in the vast majority of otherwise healthy people is close to being a non-concern.


Readers of The Heart Scan Blog and of the Track Your Plaque website know that I celebrate expansion of knowledge and information access to the public. However, I am concerned that the flip side of this growing self-empowerment is expanding potential for mistakes. It reminds me of an attorney friend, who, when diagnosed with prostate cancer, explored all manner of alternative treatments, from laetrile to heavy metal chelation to high-dose lycopene tablets. At the initial stage of diagnosis, his cancer was readily treatable. He now has widely metastatic cancer.

Maintain an open mind, but think before you commit to some crazed claim of cure, some "secret" to health, somebody's brazen but concealed attempt at steering profits in their direction.

With freedom comes responsibility. Otherwise, you might be looking for love . . .oops, I mean health . . . in all the wrong places.

Track Your Plaque APB

I'm posting this intriguing comment from the Track Your Plaque Member Forum because I would like to speak to the Member who posted it.

The Member said:

I tested at 965 last year, and while I have followed the TYP diet and nutraceutical recommendations, I was totally unprepared for my first repeat scan (at the same lab/machine) on January 29, 2008. My result was 4.0, and at first I assumed the rating scale had been changed.

I then noted that 3 of the big four arteries received scores of 0, which means the same in any scale, and that four nodules had disappeared from the scan field.



Wow!!

If this is true, it would represent the biggest success in the Track Your Plaque program--ever! It would be an incredible story to tell, to convince the public and medical community that it is indeed possible, and a cause for popping a bottle of champagne! It would also represent what I would regard as essentially a cure for coronary atherosclerosis, a virtual elimination.

While we have plenty of success in stopping the progression or reducing heart scan scores, we do not have 100% success. I wish we did. The Track Your Plaque program is, to some degree, a work in progress. We learn from experiences, continually adjust to obtain the results we desire. Even as it stands today, the Track Your Plaque program is superior to any program of heart disease prevention known--by a long stretch. But it's not infallible, it's not foolproof.

That's all the more reason I would like to communicate with the Track Your Plaque Member who posted this comment. I would also like permission to view the heart scans themselves. (I can't obtain them nor view them without the individual's permission.) While we often have difficulty judging reversal just by looking at heart scans, presumed reversal to this profound degree should be obvious, even to the naked eye.

I would like to know--in detail--precisely what steps were taken and whether there was anything unique about this person's medical history or in the program they followed. This is all in an effort to learn and help others do the same.

If you are the Member who posted this comment, I would like to hear more. Please post your further thoughts on the Track Your Plaque Member Forum, or privately through our Contact page . Or e-mail us at contact@cureality.com.

Vitamin D toxicity

It is the craziest thing.

The notion of vitamin D being easily and readily toxic has grabbed hold of many people, including my colleagues who were taught that vitamin D was toxic in medical school based on the skimpiest (and often misinterpreted) observations in a handful of unusual cases.

In my practice and in the Track Your Plaque program, we routinely use doses of 2000-10,000 units per day, occasionally more. We are guided by blood levels of 25(OH) vitamin D3. I have personally never witnessed vitamin D toxicity.

Here's an interesting graph from Dr. Reinhold Vieth. Those of you familiar with the vitamin D argument know that Dr. Vieth is among the few genuine gurus in the vitamin D world.



















From Vieth R. Vitamin D supplementation, 25-hydroxyvitamin D concentrations, and safety. Am J Clin Nutr 1999;69:842-856. (Full text is available without charge.)

In the graph, the X's represent toxicity; circles fall within the non-toxic range. (Toxicity is generally defined as a level sufficient to raise blood calcium levels, "hypercalcemia.") Note that the 25(OH) vitamin D3 levels are given in nmol/L; to convert to ng/ml units that are customary in the U.S., divide the nmol/L value by a factor of 2.5.

You will notice that toxicity is virtually unheard of until the dose exceeds 10,000 units per day. Beyond 10,000 units per day, the curve heads upward sharply and toxicity does become a possibility, though not an absolute (since there are circles above 10,000 units).

You may also notice that the curve is relatively flat from vitamin D doses between 200 units and 10,000 units (log scale on x axis; arithmetic scale on y), the range of most common doses for vitamin D supplementation.

Another perspective on vitamin D blood levels is to examine the blood levels of people who are young and obtain plentiful sun exposure. Lifeguards, for instance, have blood levels of 84 ng/ml (210 nmol/L) without ill-effect. (Sun exposure cannot generate vitamin D toxicity, because of a feedback safety mechanism in skin.) While this may not represent an ideal level since they represent an extreme, it does provide reassurance that such levels are non-toxic. I also point out these levels occur in the youthful since most people lose 75% or more of vitamin D activating capacity in the skin by their 70s. Most of us over 40 are kidding ourselves if we think that a suntan provides sufficient vitamin D.

Keep in mind that it is not necessarily the dose of vitamin D that is toxic, but the blood level it generates. I take 10,000 units of vitamin D as a gelcap per day to maintain my blood level between 50-60 ng/ml (125-150 nmol/L). This strategy helps me keep my HDL in the 70-80 mg/dl range, my blood sugar around 90 mg/dl, my blood pressure <120/80, and I no longer experience colds nor winter "blues."

Turning plaque into profit

For reasons unknown to me, I received a solicitation to invest in a company called Prescient Medical, with a slogan that caught my eye:


Detect and treat heart attacks before they occur.


The glossy brochure details their technology development strategy:

Predict(TM) Optical Catheter System--A catheter introduced into the coronary artery during a catheterization procedure to determine whether a specific plaque or vessel area is "vulnerable," i.e., prone to rupture in future.

Protect(TM) Luminal Shield--A stent-like metal device deployed into the coronary artery at the region of vulnerable plaque to prevent future plaque rupture.

The company anticipates FDA approval for their systems by 2009 and sales to begin by 2010. They predict sales of $7 billion.

Let's stop and think about this for a moment. It seems to me that, rather than pursuing the market of another stent for a "severe blockage," this company is going after the untapped procedural market of vulnerable plaque. In other words, their technology (an optical sensor technology that emits and analyzes light wavelengths to map specific plaque characteristics) identifies plaque that may rupture in months or years, followed by implantation of stent(s) that presumably prevent plaque rupture.

Thus, conceivably, many 20%, 30%, 40% etc. "blockages", atherosclerotic plaques that do not block flow and thereby pose no need for a conventional stent, will end up with this new type of stent. One patient could therefore receive multiple "Luminal Shields" in a single procedure.

When would these devices be employed? One pathway I could conceive of that my colleagues will be sure to exploit is 1) identify plaque by CT angiography, then 2) bring patient to the catheterization laboratory and perform this procedure for whatever hot, vulnerable plaques are identified. In other words, symptoms are no longer necessary. Reduced blood flow is no longer necessary. An abnormal stress test is no longer necessary. All that is required is that you have plaque. If the plaque is then determined to be vulnerable, then it is stented.

What bothers me about all this is the emerging effort to exploit this untapped market--a big one--of early heart disease as identified by coronary atherosclerotic plaque. As heart scans have demonstrated, there is an enormous amount of hidden heart disease in this world. This company has discovered a way to turn plaque into a profit opportunity, much as the statin drug industry found a way to "turn cholesterol into money."

The conventional stent market has plateaued and now has been, to some degree, battered by the drug-coated stent argument. Prescient has found a new and significant market for procedures and stents.

Is this really necessary? Why does plaque have to become a procedural disease? Doesn't it make more sense that, if vulnerable plaque is identified, that clinical trials are then designed to develop treatment strategies that modify vulnerable characteristics? Shockingly, this has not been done to any significant extent. Instead, the easiest path to a profit opportunity is to implant a "Luminal Shield."

You and I are able to inactivate, disempower, and essentially shut down plaque, while others are working furiously to convert it into a procedural profit opportunity. I personally find this so distasteful that I would sooner endorse a high-dose statin strategy than this approach.

You can view a video of my colleague, Dr. Martin Leon, on the Prescient Medical website, (or click here to go directly to the video), talking about how this technology will "change the treatment paradigm of the interventionalist from reactive to proactive." Scary stuff. Dr. Leon has made millions of dollars (probably more like tens of millions of dollars) from his support of technology companies for the interventional coronary device market.

My hope is that word of the sorts of techniques we use in the Track Your Plaque program disseminate before this sort of luminal coating idiocy gets off the ground.

(In actuality, a different version of this approach has been available for years using intravascular ultrasound (IVUS), another procedure that involves threading a catheter down each coronary artery during a catheterization procedure. IVUS can also cross-sectionally map a plaque's anatomy and identify "vulnerable" features, like a thin cap overlying a collection of semi-liquid fat ("lipid pool"). There has been some discussion of using this approach to identify vulnerable plaque followed by stent implantation, but it has never gotten off the ground and has certainly not found validation in any clinical study. By the way, any stent prevents plaque rupture, since by their very nature, the plaque contents are compressed, modified, and excluded to the exterior of the stent. Plaque rupture within a stent is very rare in its few millimeters of length. It may therefore not require some new technology to prevent plaque rupture.)

Statin mono-failure

Evan's first heart scan score in November, 2006 yielded a high score for a 56-year old male: 542.

So he put up little fuss when his doctor prescribed simvastatin at a high dose.

Evan's LDL cholesterol before simvastatin: 158 mg/dl

Evan's LDL cholesterol on simvastatin: 72 mg/dl.

By conventional standards, Evan has had an excellent response. The rest of his lipid (cholesterol) panel was unrevealing: HDL 62 mg/dl, triglycerides 78 mg/dl. Evan doesn't smoke, has a normal blood pressure, and he is not diabetic. That should do it, right?

So his doctor thought. So Evan asked if another heart scan was in order. In December, 2007, after one year of simvastatin, his second heart scan score: 705--a 30% increase over one year.

Recall that, with no effort at prevention whatsoever, the natural progression of heart scan scores is a 30% per year increase. Did simvastatin do nothing?

This is quite typical of people who do nothing more than take a statin drug. While some people do slow plaque growth (we say "decelerate") modestly on a statin drug, Evan's experience is not unusual: plaque continues to grow despite high-dose statin drug and an apparently favorable cholesterol panel.

In fact, I can count the number of people who reduced their heart scan scores taking a statin drug alone on one finger.

Statins do not represent a cure for heart disease. They cannot be used as sole therapy to reduce risk for heart attack. In fact, given sufficient time, the majority of people who do nothing more than follow this standard line of treatment (along with the equally lame low-fat diet, etc.) will have done nothing more than postpone their heart attack. Elimination of risk? Nope.

This is among the reasons we developed the Track Your Plaque approach. While not foolproof, I know of no better approach to seize control over plaque growth.

Additional conversations on clinical studies which, as with Evan's experience, demonstrated how statin drugs fail to slow plaque growth can be found in previous Heart Scan Blog posts:

Don't be satisfied with "deceleration"

Triglyceride traps

Triglycerides are a potent trigger for coronary plaque growth.

Triglycerides in and of themselves probably do not cause plaque growth. Instead, triglycerides contribute to the formation of abnormal lipoproteins in the blood that, in turn, trigger coronary plaque, like VLDL, intermediate-density lipoprotein (IDL), and small LDL. Excess triglycerides also modify HDL structure and cause you to lose HDL in the urine.

I see plenty of people who begin with triglycerides of 200 mg/dl, 300, 700, even over 1000 mg/dl. It doesn't take long before you learn what works, what doesn't to reduce triglycerides. This is especially true in the Track Your Plaque approach, in which our target for triglycerides is 60 mg/dl or less.

Here's a list of things to consider if you are trying to gain control of your triglycerides:

--Fish oil--A mainstay of treatment. The omega-3 fatty acids from fish oil are the number one most potent treatment for high triglycerides.

--Reduction of high-glycemic index foods--Most notably wheat. Everybody knows that we shouldn't eat Snickers bars or bags of licorice. But many people eat plenty of wheat-containing breads, pastas, pretzels, crackers, breakfast cereals, etc., all in the name of increasing whole grains and fiber. In reality, they are causing triglycerides to skyrocket, dropping HDL, forming small LDL, increaaing blood sugar and blood pressure, and increasing obesity.

--Eliminating fructose and high-fructose corn syrup--This ubiquitous sweetener is now consumed in enormous quantities by the average American, nearly 80 lbs per year per person. You'll find it in soft drinks, ketchup, beer, breads, breakfast cereals, and many other processed foods. You'll find none in green peppers, cucumbers, and raw nuts. Fructose causes large rises in triglycerides, as well as diabetic patterns. Don't let "fat-free" claims fool you. Take a look at the ingredients in Kraft Fat-Free Caesar Italian salad dressing, for instance:

Kraft Fat-Free Caesar Italian

Ingredients:
Water, Vinegar, High Fructose Corn Syrup, Corn Syrup, Salt, Parmesan Cheese, Part-Skim Milk, Cheese Culture, Salt, Enzymes, Contains less than 2% of Garlic, Whey, Onion Juice, Autolyzed Yeast Extract, Phosphoric Acid, Worcestershire Sauce, Vinegar, Molasses, Corn Syrup, Water, Salt, Caramel Color, Dried Garlic, Sugar ,Spices, Tamarind, Natural Flavors, Hydrolyzed Soy Protein, Xanthan Gum, Potassium Sorbate and Calcium Disodium EDTA as Preservatives, Dried Garlic, Buttermilk, Spice, Dried Parsley, Caramel Color, Sodium Phosphate, Oleoresin Paprika.



--Alcohol--While a couple of drinks a day raises HDL, exerts anti-inflammatory effects, and reduces blood pressure, more than this begins to raise triglycerides. Although I've come across no formal studies on this question, my gut sense is that beer, in particular, raises triglycerides more than wine or other alcoholic beverages. Could it be the wheat source of beer? Or its high-fructose corn syrup? I don't know, but beer is the least desirable form of alcohol of the choices we have.


Following these simple steps, it is unusual in my experience that you cannot achieve a triglyceride level <60 mg/dl. Rarely do we need to add fibrate drugs or other prescription agents to reduce triglycerides.

High-dose fish oil for Lp(a)

Lipoprotein(a), or Lp(a), is a problem area in coronary plaque reversal.

While our current Track Your Plaque record holder for largest percentage reduction in heart scan score has Lp(a), it remains among the more troublesome lipoprotein patterns.

One unique treatment for Lp(a) is high-dose omega-3 fatty acids from fish oil. While the data are relatively meager, there is one solid study from Lp(a) expert, Dr. Santica Marcovina of the University of Washington, called "The Lugalawa Study."

In this unique set of observations, 1300 members of a Bantu tribe living in Tanzania were studied. What made this population unusual is the fact that two groups of Bantus lived under different circumstances. One group lived on Nyasa Lake (3rd largest lake in Africa and reputed to have the greatest number of species of fish of any lake in the world) and ate large quantities of freshwater fish providing up to 500 mg of omega-3s, EPA and DHA, per day. Another Bantu group lived away from the lake as farmers, eating a pure vegetarian diet without fish.

Nyasa Lake












This situation among genetically similar stock provided a unique learning opportunity, a chance to assess whether different diets influenced Lp(a) levels.

The results: The fish-eating Bantus had an average Lp(a) level of 14.0 mg/dl. The farming, non-fish eating Bantus had an average Lp(a) of 27.0--a 48% difference. Curiously, a comparison of the apo(a) component of Lp(a) between the groups also showed that the fisherman expressed fewer dangerous small apo(a) forms, despite equal potential to express both.

The Lugalawa Study opens the question of whether similar results can be obtained not by moving to Tanzania and fishing Nyasa Lake, but by mimicking their experience by supplementing high doses of omega-3 fatty acids.

It's an intriguing question. In the Track Your Plaque program, we have no specific experience with this strategy, but it is certainly worth exploring further.

Watch for two upcoming Special Reports on the Track Your Plaque website in which we will be detailing 1)unique strategies for Lp(a) reduction, and 2) the usefulness of high-dose fish oil for coronary plaque reversal.

Interesting enough for a Virtual Clinical Trial?

The many faces of LDL

Pam has an LDL cholesterol of 144 mg/dl.

To most people, this means that she has a mildly elevated LDL value. Many people would respond by cutting the saturated fat in their diet. Most physicians would concur and talk about prescribing a statin drug.

Let me tell you what an LDL cholesterol of 144 mg/dl means to me:

1) It could mean an LDL of all large particles (which is good) or an LDL of all small particles (which is very bad). Or, perhaps it's some combination of big and small. I can't tell which just by knowing that LDL is 144.

Small LDL responds to a diet reduced in processed carbohydrates and wheat flour; large LDL does not. Small LDL responds in an exagerrated way to niacin; large LDL does not. It makes a difference.

2) It could mean that, hidden within LDL, is lipoprotein(a), or Lp(a). Recall that Lp(a) is a high-risk genetic pattern that can provide the false appearance of high LDL cholesterol. If Pam were prescribed a statin drug, it would have little effect and little benefit. (See Red flags for Lipoprotein(a).)

Knowing that Pam has Lp(a) can point us in an entirely different direction than just LDL cholesterol. It might mean high-dose fish oil, a more serious approach to niacin, hormonal treatments like DHEA or testosterone. It might mean more attention to warning your children about the possibility that they, too, might share this genetic trait.

3) It could mean both small LDL and Lp(a) are present simultaneously, an especially dangerous combined pattern that is among the highest risks for heart disease known.

4) Because Pam's LDL of 144 mg/dl was not measured, but calculated, it means that it is subject to tremendous inaccuracy.

In my office, calculated LDL cholesterols can be inaccurate by 50 or 100 mg/dl--commonly. So Pam's LDL of 144 mg/dl could really be 70 mg/dl, or it could be 244 mg/dl. Once again, it's a big difference.


Just like The Three Faces of Eve, the 1957 film in which Joanne Woodward played the three wildly different sides of Eve's personality--the daytime Eve White, the fun-loving and daring Eve Black, and Jane--so can LDL assume several different faces, all with different personalities, different implications.

Accepting LDL cholesterol as LDL cholesterol is a fool's game. It is only a starting point, nothing more. Accepting a statin drug based on LDL is, likewise, a trap fraught with uncertainty, the potential for limited or ineffective results, the price being your heart and health.

Track Your Plaque data abstract

An extraordinary thing happened about 2 1/2 years ago.

While we have been following the Track Your Plaque program for coronary plaque regression for nearly 10 years, about 2 1/2 years ago we witnessed an extraordinary surge in success--bigger, faster, and more frequent drops in heart scan scores.

Up until then, we did witness significant reversal of coronary plaque by heart scan scores. We were planning to publish the data to validate this approach, but then . . .

Heart scan scores starting dropping not just 2%, or 8% . . . but 24%, 30%, 50% and more. Why? I attribute the surge in success to the addition of vitamin D.

Unfortunately, it also meant that the preceding 8 or so years of data lacked experience with supplementing vitamin D. The hundreds of participants in the Track Your Plaque program had not, until then, included vitamin D in their program.

So I decided to start from scratch (from the standpoint of data collection, not for the participants). That also meant that the preceding years of experience went unreported, though even that data far exceeded the results of what is achieved in conventional heart disease prevention.

Thus, the data I presented at the Experimental Biology Proceedings (FASEB 2008) in San Diego this week included only experiences in the group of participants that included vitamin D in their program, with data collected until mid-2007. The number of experiences is therefore modest.

However, the Track Your Plaque experience, as reported, far exceeds any prior experience in coronary plaque regression.

The full abstract will be published in the Track Your Plaque website.

Small fish oil capsules

Many people complain about the size of fish oil capsules. Let's face it: They're usually big and kind of smelly.

Women in particular struggle with big capsules. This becomes a real problem when somebody requires high-dose fish oil for treatment of post-prandial (after-eating) abnormalities, high triglycerides, or lipoprotein(a), when 6 or more--occasionally up to the equivalent of 20--standard fish oil capsules are required.

I came across a small capsule alternative for people who struggle with the big capsules. It's a product called Learn from PharmaOmega, a source of super purified fish oil.

The Learn product is actually made for children, since omega-3 fatty acid supplementation has been linked with improved intellectual performance. But the small capsule size is convenient for women and other people who would like to avoid the big standard-sized capsules.

Each capsule is about 60% of the size of a standard fish oil capsule (the smaller capsule in the photo, next to a standard size fish oil capsule), yet contains 375 mg EPA + DHA per capsule, 25% more than standard capsules (which contain 300 mg per capsule). The ratio of of EPA:DHA is a little more heavily weighted towards EPA with a 5:2 ration, compared to 3:1 of standard capsules. The capsules are also faintly orange flavored and non-fishy.

Low-carb eating for diabetes

Jenny provided permission to reprint her very excellent introduction to low-carbohydrate eating for people with diabetes. You can also view the original version on her Diabetes 101 website.

Jenny is a stickler for monitoring the effects of blood sugar. We might take some lessons from her experiences for improving management of people with metabolic syndrome or borderline blood sugars. In other words, monitoring the blood sugar-raising effects of various foods and food portions can provide great feedback on what foods are preferable, what undesirable, given your physiology.

Even if you are not a diabetic, Jenny's discussion is must reading to gain a better understanding of food choices, particularly carbohydrates. Along with seizing control of health, she has also gained deep wisdom in how to best manage this disease and its physiology.


Introduction to low-carb nutrition for diabetics

It's carbohydrates that raise blood sugar.

Sugars and starches, not the fats that dietitians have been warning you about for so long. If you've been testing your blood sugar after meals, you've probably noticed that already and you are starting to understand why a healthy diabetes diet will have to be one that limits carbohydrates to an amount that doesn't push your blood sugar up over the level where you are damaging your body.

But if your previous experience with restricting carbohydrates involved doing a weight loss diet like Atkins or Protein Power, which worked well for you until you crashed off it entirely and gained back all the weight you'd lost, you may be hesitant to embark on another course of dieting that requires some carb restriction.

I've been there myself. I've done the extremely low carb diet Dr. Richard Bernstein recommends for months on end. I did Protein Power for 3 years. And I've gone on the "Eat all the carbs you didn't eat over the past three years all at once" diet, too. The following observations grew out of my 8 years of experience with learning how to make carb restriction work long-term.

Unlike much of what you've read before, there are no scholarly references for this section. It's based entirely on my own observations and the experience of many dozens of people who have participated in online discussion groups devoted to low carb dieting and diabetes.


Weight Loss Diets Usually Fail but Diabetes Diets Can't Afford To Fail

People who adopt a low carb diet to lose weight tend to start out with great enthusiasm, adapt extreme dieting strategies, swear they will never eat another piece of bread or french fry for the rest of their lives, lose some weight, stall out, burn out, and slink back to their old diets, where they gain back all the weight they lost and more.

This is not a surprise. People on any diet, including low calorie and low fat, do the same thing. The body is very resistant to weight loss and deeply buried instincts in our brains do everything they can to maintain our weights, no matter how unhealthy they might be.

But while this pattern of dieting may be tolerable for those who are dieting to shed a few pounds before their class reunion, it spells disaster for those who must change their diet in order to prevent the high blood sugars that result in amputation, blindness, kidney failure and heart attack death.

Low carbing for diabetes means low carbing for life, long after the thrill has worn off of eating that runny brie and steak. Despite the hype in the diet books, it is not easy, simple, and fun. I know only a handful of people who have been able to sustain a low carb lifestyle for more than five years. And that is after years of online participation in low carb groups.

What you'll find below is what I've found works for me. I used a low carb diet to control my blood sugar for more than five years and have gone through the whole cycle, from enthusiasm, to boredom, to burnout, to saying "To hell with it, we've all got to die some time!" to starting all over again determined to avoid the mistakes that sent me round the bend the first time.


How Many Grams of Carbs to Eat? As Many as Allow You to Reach Your Blood Sugar Targets

When people think about adopting a lower carb diet, their first question is almost always, "How many grams of carbs can I eat at each meal?" Most of the diet books will answer that question with a hard and fast number. Atkins, for example, tells you to start out with 20 grams a day. Protein Power starts you at 30 grams. And Dr. Bernstein suggests 6 grams for breakfast and snacks and 12 grams at lunch and dinner.

Adopting these very low carbohydrate limits will control your blood sugar very nicely. But over time, many people find that sticking to a diet this low in carbohydrate becomes impossible. That's why I'm going to ask you to throw away all those diet books and try a new approach to restricting carbs.

What you will do is to try the strategy used by the people from the alt.support-diabetes newsgroup who informally call themselves "The 5% Club" because their A1c test results fall in the 5% range which doctors consider normal: use your blood sugar meter after each meal to determine how many grams of carbs you can eat and still meet a healthy blood sugar target.

You will start out by measuring your blood sugar one and two hours after each meal. Write down what you ate and observe what it did to your blood sugar. If a meal allows you to reach your blood sugar targets, try eating it again on a different day and test it test again, possibly at a later time, to make sure that your good numbers weren't just a result of slow digestion.

If you end up too high after a meal, the next time you eat it, cut back on the portion size of the carbohydrate elements in the meal and test again. Do this until you can hit your targets, or flag the carbohydrate-containing foods in that meal as ones your body can't handle.

What you're doing here is creating what newsgroup activist Alan S. calls, "a low spike diet" rather than a low carb diet. He can achieve normal post meal blood sugars by eating as many as 30 or 40 grams of carbohydrates at a meal. Others will find that they need to eat a lot less than that amount to hit safe post-meal blood sugar targets.

Usually how much carbohydrate you can manage has something to do with your body size. The more you weigh, the less each gram of carbohydrate you eat will raise your blood sugar. Those of us whose weight is less than 150 lbs often find that we can eat between 12 and 20 grams of carbohydrate and still reach normal blood sugar targets without the help of medications, and that we can add perhaps another 10 or 20 grams more, with medications. People who are much heavier can often eat 30 or 40 grams per meal and still reach their blood sugar targets. In general, men can eat more carbohydrates and still reach their targets than can women, again, because of their larger body size.


How to Learn How Much Carbohydrate is in Your Food

To make this system work, it helps if you start to learn how many grams of carbohydrate are in the foods you eat. That way you won't have to test hundreds of foods once you've learned how a representative sample affect you.

The best way to learn how many grams of carbohydrates are in the different foods you eat is to read food labels carefully, invest in a nutritional guide like one of Connie Netzer's books of nutritional information, download nutrition software like LifeForm (http://www.lifeform.com) or use online calculators like Fit Day (http://www.fitday.com). Software and online sites will compute the amount of carbohydrates and other nutrients in your meal for you as long as you know the portion size.


Learn about Portion Sizes!
This brings up an important point: When you estimate how many grams of carbohydrate there are in a portion of food, it is very important to find out if the amount of food on your plate corresponds to the amount in the "one serving" listed on a label, in a book, or in your software.

The best way to do this is to invest in an electronic food scale and to weigh your foods for a few weeks until you get the hang of estimating portion size. You can get a good food scale at a gourmet kitchen shop for $25 to $40 dollars. This food scale may be the best nutritional investment you'll ever make.

Once you start using your scale, you will find that the muffin you bought at the coffee shop weighs 8 ounces, which is fully four times the 2 ounces that most food databases give as "one serving" of a muffin. When you read that a mythical 2 ounce portion of muffin contains 27 grams of carbohydrate you will realize why that 8 ounce coffee shop muffin with its 108 grams of carbohydrates sends your blood sugar into the psycho zone!

With ice cream, when you weigh your ice cream on a food scale, you'll quickly see that the "one portion" listed on the package turns out to be only a few teaspoons' worth. That bowl you've been considering as one portion of ice cream weighs in as four servings or 72 grams of carbohydrate and 600 calories, which may explain its damaging effect on both your blood sugar and your waistline.

This may sound like a lot of work, and when you first start, it is. But after you do it for a few weeks you'll find you have memorized the carbohydrate gram counts and the portion sizes for the foods you usually eat, and once you have tested your blood after eating these portion sizes, you won't have to test every time you eat a favorite meal, because you will know what it is going to do to your blood sugar.


Eating Away from Home

The biggest challenge you'll encounter as you start learning what you can eat will be eating away from home. You aren't going to be able to weigh restaurant foods nor can you look up the nutritional values of many restaurant offerings--though many of the common fast food outlets do provide nutritional information online--though often without listing portion sizes.

That makes it a very good idea to avoid starchy or sugary restaurant foods or, if you do eat them, to eat only a small portion of what you are offered. Measure your blood sugar an hour or two hours after eating if you aren't sure about how a restaurant food will affect you.


Fat and Carbs Eaten Together will Digest Slowly

Foods with a lot of fat in them take longer to digest than those without a lot of fat. This is why pizza and ice cream often give deceptively good readings on your meter. If you test a meal and see a reading that is too good to be true, be sure you test at 3 or four hours after eating.


The Truth About Pasta

Pasta was long recommended to people with diabetes as a food that would not raise blood sugar and you will still see it starring in many cookbooks and magazines intended for people with diabetes.

However, if you test pasta 4 or 5 hours after eating, you may get an unpleasant surprise. This is true with the so-called "low carb" pastas, too. These foods give you excellent readings at one and two hours because they are resistant to digestion so they don't turn into glucose right away. But five hours later, they do break down into glucose and when they do, the 52 grams of carbohydrates found in each 2 ounce serving of pasta will hit your blood stream with a nasty wallop. (Not to mention that you almost need a microscope to see a 2 ounce portion of pasta. Most people's idea of a portion of pasta is closer to 6 ounces--and 156 grams of carbohydrate!)

If you have pasta for dinner and don't see a peak 3 hours later, be sure to check your fasting blood sugar the next morning. You may see the blood sugar rise there, too.


Sugar Alcohol and "Sugar Free" Foods

The sugar alcohol used in so-called "sugar free" foods can also show up in your blood sugar an hour or two after you'd expect to see them, especially the maltitol used in "sugar-free" candy. At least half of the sugar in Maltitol does turn into glucose in your blood stream and it can raise your blood sugar, but the rise is delayed so you may miss it on testing. So if a "sugar free" food seems to be kind to your blood sugar, try testing it an hour or two after your first tests. Erythritol is the one sugar alcohol that usually does not show up in your blood sugar.


Dealing with Limited Blood Testing Supplies

In in ideal world, we'd all have all the testing supplies we needed to control our blood sugar, but in real life blood sugar test strips are very expensive and many insurers sharply limit the number of strips people with Type 2 diabetes can get each month.

Here are some strategies that can help you if your access to strips is limited.

If you only have 50 strips to get you through a month, plan out what you are going to test ahead of time. Pick one of your favorite meals, and test at 1 hour after eating the first time you eat it and 2 hours after eating the second. Do this with a couple different meals and see if there's a pattern as to when you see the highest reading--whether it is at one hour or two. Then choose another meal and test it at the time when you saw the highest reading in the earlier meal. If you ever get a surprisingly low reading, try testing an hour later or earlier, to make sure you aren't missing the peak.

Make the goal of your testing be learning how many grams of carbs you can tolerate in one meal. If you learn that 30 grams is your upper limit, use software and your scale to find portions of other foods that will also clock in at 30 grams or less. Test one or two of these, and if you see the result you expect, you don't have to test every time you eat these foods again.

Wal-mart sells a cheap and effective blood sugar meter with strips that cost one half as much as other vendors. Some drug stores also sell store brand meters with cheaper strips. If you need more strips, consider the $50 you pay for another 100 strips an investment in your health. It's far better to spend that $50 now, than to spend it on expensive doctor bills caused by complications you don't need to develop!


Keep the focus on Achieving your Blood Sugar Goals

By testing after meals, you'll learn how many grams of carbohydrate your own, unique, body can handle. And more importantly, you'll also be able to decide if you are going to be able to control through diet alone, of whether it is time to talk to your doctor about supplementing dietary control with drugs.

Many people are so excited to learn that they can achieve normal blood sugars by cutting way back on carbohydrates that they become zealots for low carb dieting. I've been there and I've done that. But it's important not to get too carried away with a "Carbs are Evil" mentality which makes it a matter of religious zeal never to let evil carbs cross your lips again. Like all conversions this one tends to fade out in time. And as we said at the start of this chapter, your ultimate goal is to maintain your blood sugar targets for the rest of your life. So the safest approach is to get the most blood sugar benefit you can out of restricting carbohydrates, but restrict them to a level you can maintain year in and year out.

Most importantly, I have learned it is best to treat carb restriction as a strategy, one of many, which used in combination with other strategies including medications if needed, can give you normal blood sugars, rather than the One and Only True Way. If you can be flexible and find more than one tool to help you meet your blood sugar targets, you are more likely to be able to maintain those excellent blood sugars for years to come.


Eliminate "Habit Carbs" and Concentrate on "Value Carbs"
When people think about restricting their carb intake they assume this means never eating any of their favorite foods again.

But for many of us, this doesn't have to be true. Why? Because a quick look at your daily carb intake will often reveal that the bulk of the carbohydrates you are eating are what I call "habit carbs." These are the carbs you eat without a second thought because they are there. Not because they taste good. Not because you couldn't live without them. Just because you're in the habit of eating them.

Here is a list of some prime "habit carbs."

Steam table mashed potatoes

Limp french fries

Squashy hamburger buns

Cardboard toast

Cold home fries

Stale boxed cookies


How many of these flavorless, starchy foods are you consuming everyday just because they're there? Probably more than you realize. So before you lift that fork-full to your mouth, ask yourself, "Is this food thrilling me?" If not, put it down. This should go a long way towards getting your carb intake down.

What I'd call "value carbs" are those carb-rich foods that really do mean something to you. I'm not going to lie to you. You are not going to be able to make them the mainstays of your diabetes diet. But by using the strategies describe below, you should be able to eat enough of these foods to keep yourself from feeling deprived--without destroying your health.


Don't Create "Forbidden Foods!"

If you are one of those people who could live happily on Purina People Chow, you can skip what follows. But if food has been important to you, and if you have hitherto had a long and emotionally satisfying relationship with food, or if, like me, baking from scratch was one of your favorite ways to show love and express creativity, restricting your carbohydrate input will mean that a whole lot of what you've been eating (and baking) up until now is suddenly, completely, off limits. I can't eat cake and get a healthy blood sugar level. Even with two different diabetes drugs in my system. I can't eat cake even with an insulin shot before I eat it. I love cake but there is no way I can eat more than a bite or two without seeing very high blood sugars and there is no way I can eat two bites of cake and be happy. The same goes for french fries and Thai noodles.

During the first enthusiastic weeks of exploring carb restriction most people deal with this kind of discovery by coming up with new recipes and finding new, delicious and healthy things they can substitute for old, high carb standards. They appreciate the way cutting way back on carbohydrates curbs their hunger and makes food much more manageable. This is good and it is why long term low carbing is possible. But our old favorite foods do not go away that easily.

If you decide that some food you have been eating and enjoying all your life will never again cross your lips, it is almost 100% guaranteed that you'll end up pigging out on that very same food at some time in the future, hating yourself, and even beginning a binge that can throw you completely off your diet for months.

It might not happen the first month you are restricting your carb intake or even the first year. It took me three years of low carbing to get to where I crashed off my stringent low carb diet. But eventually it happens, and because after almost a decade of counting my carbs I've learned that I will never lose my love for certain foods that don't love me, I've put a lot of time into finding a way of restricting my carbohydrate intake in a way that avoids the buildup those feelings of deprivation that eventually lead to long periods of unwise eating.

The key, for me, is to build safety valves into my diet. I don't call them "cheats" or "bad foods" for reasons I'll get into later. I call them "off plan" foods because they are not food I can make an ongoing part of my daily food plan. Because my goal is life-long blood sugar control, I accept that I will occasional eat "off plan" and that this is okay as long as I am meeting my blood sugar targets most of the time. "Good enough" control that I can adhere to year in and year out beats a few months of perfection followed by crashing off the diet entirely and ruining my health. Here is one way to approach doing this:

Do the Diet Straight for a Month or Two Before You Try Off-Plan Goodies

As you learn what foods raise your blood sugar and what foods don't, you will almost certainly find that there are a lot of foods you used to love that don't work for you anymore. Waffles for breakfast, coffee cake at coffee break, three slices of pizza with crust, a burger with a bun and a side of fries are just a few of the foods that it is almost certain will not allow you to meet your post-meal blood sugar targets.

As you keep using your meter to test what you eat, if you are like most people with diabetes you'll also learn that some of the so-called "low glycemic" foods and the supposedly "healthy" whole grains that nutritionists recommend for people with diabetes won't work either. Oatmeal and whole wheat bagels raise my blood sugar far too high, so does cracked whole wheat, whole wheat bread, and brown rice.

If the dietician tells you a food is good for you, but your meter tells you it is raising your blood sugar to a level that is high enough to cause complications, you will have to listen to your meter. Your meter will tell you what is safe to eat and for the first couple of months while you are learning how to get your blood sugar under control and how bring those high blood sugars down to normal levels you will have to accept that you can only eat those foods that don't cause spikes.

If you attempt to add in off-plan foods before you are solidly on-plan you may never really get into the swing of eating a diet that controls your blood sugars and you may not get to where your body learns to enjoy the lower carb foods that don't give you blood sugar swings.

But after you've gotten your blood sugar under control, nothing horrible will happen if you make room for a small portion of some high carb treat every now and then.


How to Add Off-Plan Foods to the Plan

If you've avoided bread for a couple months, the humble roll in that restaurant bread basket may start to call out to you with an irresistible siren song. If you give in and eat it, with each bite you may find yourself feeling as if you are doing something incredibly sinful--the way you might have felt if you had eaten a whole box of chocolates in the past.

That feeling is the sign that you're heading for trouble. You've created a "forbidden fruit" and sooner or later that forbidden fruit is going to get you. You may find yourself thinking about that roll, craving another, sneaking off to eat one where nobody knows you, or, alternatively, you may declare that you will never again eat a roll ever--and then ruin your Thanksgiving holiday when you go to Aunt Glenda's and refuse to eat even a single one of those wonderful rolls of hers you've eaten every year of your life which say, "This is the family Thanksgiving" to you.

It is far better to make a bit of room in your diet for high carb treats so that they don't build up a charge. If you do this, you'll find that they almost never taste as good as you remembered, and you'll be able to leave them behind without turning them into an object of obsession.

Just knowing that you can eat some specific off-plan food at some future time, when it is scheduled, makes it that much easier to say, "No thanks" to it, and maintain your healthy blood sugar the rest of the time.


How Often Can You Eat Off-Plan?
How often you have an off-plan food depends a lot on your dietary goals, how high your blood sugar is before you eat carbs, and whether you are willing to exercise after eating. It also depends greatly on what medications you are taking for your diabetes. Whatever I eat, I try to keep my blood sugar below 120 mg/dl (6.7 mmol/l) at 2 hours after any meal.

Forty minutes of cardiovascular exercise will burn off a lot of extra carbs, so if you exercise regularly, try to eat your high carb treat before you head for the gym.

If you're trying to lose weight, you may have to keep off plan treats few and far between. When I was actively losing weight on a low carb diet without medications I ate one off-plan meal about once every two weeks.

Once I reached my weight loss goal I loosened up a bit but I found it best to cycle between weeks of eating a strict very low carb diet, and then a week of eating slightly more carbs--but I tried very hard not to ever anything that would cause my blood sugar to be over 120 mg/dl (6.7 mmol/L) at 2 hours after a meal because doing so makes me feel rotten.


Throw Away the Vocabulary of Self-Destructive Dieting

When you eat something with carbs in it, don't think of it as a "cheat." Cheating is what you do when faced with an authority figure--your 9th grade math teacher or the IRS. But you are the one in control of what you eat. So when you eat something that is off-plan, you should stop thinking of it as "getting away with something" and treat it instead as something you've decided to do--for a reason that should be clear to you while you do it.

If you keep eating things that were not what you had intended, rather than beating yourself up, it's time to reconsider your food plan and figure out why it isn't working. Are you having trouble finding foods in restaurants that don't raise your blood sugar? Maybe it's time to bring your lunch along to work for a while, or to find new place to dine.

Are you bored with what you have been eating? Google for good low carb recipes you can try at home. There are thousands of them. If you use the Google Groups search and look for messages in alt.support.diet.low-carb that start with "REC" you'll find a treasure trove of ideas to try.

Keep the vocabulary of sin and guilt for the confessional. You're going to eat a lot of things in the years to come that will mess up your blood sugar. But if you are kind to yourself and dust yourself off after you mess up and keep on going, doing the best you can to hit your blood sugar targets, you may very well end up healthier than many people who do not have diabetes. The important thing is to keep at it, doing the best you can and forgiving yourself when the best you can do isn't as good as you wish it was.


Know Your Limits
I've learned the hard way I can't eat half a blueberry muffin, so I don't even try portion control for that particular food. I know blueberry muffins are trouble and I also know that I will eventually eat one. That's just how it is, so every blue moon or so I eat a blueberry muffin, experience the miserable high blood sugars that follow, and then remember why I don't eat muffins every day any more. What I don't do is fool myself that I can buy a muffin and only eat half. Everyone has a few foods that fall into this category. Treat them with caution!


Eat Off-Plan Foods Out of the House
I've learned the hard way that if a big box of something full of carbs is in the fridge, bad things are going to happen. So I try to eat my off-plan foods away from home. I eat my muffins or cookies at a coffee house. I have a slice of pizza at a pizzeria. I don't buy a box of muffins or a whole pizza and bring them home.

Getting this strategy to work requires that your whole family understand what's at stake. It took me a couple years of harping on what "complications" means, but by now, my family understands that if my blood sugar is too high, I'm damaging my body. They want to keep me around for a while, so they understand that there are some foods that shouldn't be brought into the house--ever.

When other family members want to have treats at home, they are kind enough to buy things I don't like. For example, if someone wants Ben & Jerry's they buy the Chunky Monkey flavor that I find revolting, not the New York Fudge. By the same token, when my kids lived at home, I didn't buy them the brands of cookies I can't resist. There are plenty of others cookies they liked that don't tempt me at all, and those were the ones in the cupboard.

Over the years the nondiabetic members of my family learned that no one is doing themselves a favor scarfing down 300 grams of fast acting carbohydrate every day--particularly not people with a family history of diabetes and heart disease!


Medications Can Help

I'm not a big fan of medications because I've learned the hard way that drug companies lie about side effects and some of these side effects are permanent and can ruin your life. But I learned the hard way, too, that some of us (like, say me) can't get normal blood sugars no matter how low our carb intake. For us, adding a diabetic drug or two to our daily regimen may be the only way we can get normal blood sugars without a life of tormenting self-denial.

Drugs I have found useful over the years include metformin, precose, and post-meal insulin shots. The new incretin drugs, Januvia and Byetta help some people make dramatic improvements in their blood sugar, but the way that they work makes it necessary to eat a slightly higher amount of carbohydrates with them because they only work when your blood sugar rises over a certain threshold. Even with these drugs (including Januvia) I've never been able to eat more than 120 grams of carbohydrates a day, but after many years of eating an extremely low carb diet--which was the only diet that would control my blood sugars--120 grams of carbs a day feels like a completely normal diet!


Be Aware of Rising Insulin Resistance

Some people may find that eating a low carb diet is not enough to control their blood sugar because they are very insulin resistant. Perhaps they have been diagnosed with PCOS, or have to take a drug, like Prednisone that increases insulin resistance. The book, Dr. Bernstein's Diabetes Solution by Dr. Richard K. Bernstein, the distinguished diabetes doctor, recommends Metformin as an appropriate drug for patients on a low carb diet whose blood sugars are still not completely controlled. It isn't a cure by any means, just one more tool you can use to keep blood sugars under control, and if you limit your insulin resistance you may solve both weight and hunger problems that otherwise can derail your diet.

You can read more about the different drugs available to help control blood sugars HERE. Just remember that all these diabetes drugs work best when you combine them with some level of carbohydrate restriction. How much restriction? Test your meals one and two hours after eating, and your blood sugar meter will tell you exactly how much.


Top Medical Journal Publishes Landmark Study Showing Very Low Carb Diet Most Effective and Safest for Lipids etc.

In case you are still being given out-of-date medical or nutritional advice by people who tell you that a low carb/high fat diet will give you a heart attack, take a look at this recently published study, which appeared in the Journal of the American Medical Association.

This study found that an Atkins style low carb diet not only caused double the weight loss of the low fat diet at the end of one year, but it did not adversely affect cholesterol levels.

This finding, added to the Women's Health Initiative finding (after $40 million dollars of research) that low fat dieting does NOT prevent heart disease, should lay to rest any last fears you might have about the impact of cutting carbs on your health.

The findings of this study, are not news to anyone who has tried a low carb diet and stuck with it for any period of time, but they appear to amaze the entire medical community who continue to cling to their to the "Fat is Bad" religious belief long no matter what evidenced-based medical studies might come up with.

Bottom line: You can cut your carbs way down, replace carbs with fat, and await the better health this kind of eating will provide.

To Get More Help with Making a Low Carbohydrate Diet Work

My "Low Carb Facts and Figures" site, which now shares this server, has more information I collected back in the days when I used a low carb diet for both weight loss and blood sugar control.

You'll find articles there that address a few of the issues people run into while eating a very low carb diet,which are not answered in a completely honest fashion by the people who sell diet books promising you can lose weight easily while gorging on all your favorite foods--which, sadly, is 99% of all authors writing diet books.

Interview with an outspoken advocate of truth in diabetes

I stumbled onto Jenny Ruhl's Diabetes Update blog after I received several very insightful comments to this blog whenever I posted a discussion on diabetes or pre-diabetes/metabolic syndrome.

Who the heck was this commenter who clearly had deep insight into diabetic issues?

It turned out to be Jenny Ruhl, a woman who learned her lessons the hard way: by receiving a belated diagnosis of (an unusual form of) diabetes, then receiving plenty of mis-guided advice from physicians on diet and treatment. Reading her many blog posts and websites, you get the clear sense of how hard this individual worked to gain the depth of knowledge she's acquired, on a par or superior to most diabetes specialists.

And she minces no words in expressing her heartfelt and carefully considered opinions. But that's what I look for: people who are unafraid to voice opinions that may not be consistent with the flow of conventional thought, but ring true and prove effective.


Dr. Davis: From your blog and websites on diabetes, it is clear that you exceptionally knowledgeable in the world of diabetes, metabolic syndrome, and related disorders. Can you give us a little background on how you came to this quest?

Jenny: Though I was told I was a "classic type 2" [diabetic] by my doctors, nothing I read about diabetes corresponded to my own experience. I knew my diabetes had not been caused by obesity because I'd been a normal weight all my life until my blood sugars went out of control at which point I developed ravenous hunger and gained a lot of weight very quickly.

I also wondered at the huge gap between what Dr. Bernstein said was a normal blood sugar and what my doctors told me was a safe blood sugar for a person with diabetes. The people I met who followed Bernstein's very low carb diet had much better blood sugars and far fewer complications, but my doctors dismissed this as irrelevant. So I decided to do some research to find out who to believe. I plunged into the medical journal articles that had recently been made available on the web to see if I could answer two questions: What causes diabetes? and "What does science actually know about what blood sugar levels damage organs?"

The result was the information that became the basis for the Blood Sugar 101 site. Initially, I attempted to sell it as a book, but editors told me that though what I'd learned was "fascinating" it would be "over the head" of the typical health book buyer who wanted simple explanations and if possible, a simplistic slant towards "cure." Fortunately, the very strong response and high traffic volume to the web site proved that, as I had thought, there are a lot of people who do want more than an oversimplified overview and who, given the information they needed, were able to make huge positive changes in their health.


Dr. Davis: What do you think your life would be like if you hadn't pursued this unique course?

Jenny: Possibly a lot shorter.

People in my family die of heart attacks in their 50s, probably from undiagnosed high blood sugars. The pattern of the type of diabetes I have is to have a normal fasting blood sugar and an extremely high post-meal blood sugar after consuming very few grams of carbohydrate. When doctors diagnose using only the fasting blood test, they miss those highs, which research is now finding to be a primary cause of heart disease.

I also would have been a lot fatter. My doctors told me that I was packing on 20 lbs a year due to "normal menopausal changes" and that there was nothing I could do about it. Lowering my carbs significantly dropped all the weight I had gained and I still weigh a lot less now than I did in 1998.


Dr. Davis: You've been a keen observer of the diabetes scene for some years. Have you discerned any important trends in both the public's perception of diabetes as well as how diabetes is managed in the conventional world?

Jenny: The huge difference I see is that, over the last decade, the online diabetes community has learned the value of cutting back on carbohydrates and shooting for truly normal blood sugar levels. So people who put some time into researching diabetes online and talking with those of us who have succeeded in avoiding complications will learn that they do not have to settle for very high blood sugars and deterioration their doctors think inevitable.

Unfortunately, the media have put most of their energy into promoting the discredited idea that diabetes is caused by gluttony and sloth and to promoting the equally discredited idea that people with diabetes should eat a high carbohydrate diet and avoid fat.

So for now there is a huge divide in the quality of life of those people with diabetes who educated enough to go out on the web and educate themselves and those who get their diabetes information from doctors. Sadly most doctors still encourage patients to eat low fat/ high carb diets, and counter the very high blood sugars this diet produces with oral drugs of questionable efficacy, while assuring patients they will be safe if they maintain blood sugar levels that meet the American Diabetes Association's recommendations, though a mass of research shows these are high enough to produce every single diabetic complication possible.


Dr. Davis: I understand that you've released a new book, Blood Sugar 101. How is your book unique in the world of diabetes books? Who should read Blood Sugar 101?

Jenny: Blood Sugar 101: What They Don't Tell You About Diabetes differs from other books in that it gives the reader a much deeper understanding of what is really going on in their bodies as their blood sugar control breaks down and what sciences knows about how abnormal blood sugars cause complications. Then it gives the reader the tools they need to find what diet and/or drug regimen will brings their own, unique, blood sugars down to a truly safe level.

Unlike some books, this one does not present a one-size-fits-all solution, but recognizes that Type 2 diabetes is really a catch-all diagnosis that covers a lot of disorders that behave quite differently. That is why what works for one person with diabetes may not work for another.

Because this book provides details available nowhere else about the physiology of diabetes and the drugs available to treat it, readers will find the information they need to work with their doctors to craft a regimen that brings their blood sugar into the range that preserves and improves their health.


Dr. Davis: Before we close, tell us a little about yourself outside of your diabetes advocate role.

Jenny: I live in rural New England and am a passionate gardener. I've been online since 1980 when I was part of the team at IBM that developed the first commercial email program, PROFS. I got involved in online discussion groups in 1987 and have been messaging on bulletin boards ever since.

I was a professional singer/songwriter in Nashville in my youth and spent my middle years as a bestselling author of books about consulting. Right now a lot of my energy goes into managing the financial and software side of a family business that makes hand made pocket tools for collectors.


Dr. Davis: Thank you for your great insights, Jenny!

The Marshall Protocol and other fairy tales

True to form, Dr. John Cannell has published yet another wonderfully insightful Vitamin D Newsletter.

One item caught my eye, a response to a question about the Marshall Protocol. I, like Dr. Cannell, was inundated with questions about this so-called protocol, which amounts to little more than the unfounded speculations of a non-physician, actually someone not even involved in health care.

In all honesty, I blew the whole issue off after I read Dr. Marshall's rants. They smack of pure quackery, though from somebody who clearly has a command of scientific lingo. To Dr. Cannell's credit, he took the time and effort to construct a rational response in the latest issue of the newsletter. I reproduce his response here:



Dear Dr. Cannell:

I understand Dr. Marshall conducted a study and found vitamin D is bad for you. What kind of study did he do?

Mary, Minneapolis, Minnesota


Dear Mary:

I have been inundated with letters asking about Professor Marshall's recent "discovery." Some have written that to say they have stopped their vitamin D and are going to avoid the sun in order to begin the "Marshall protocol." The immediate cause of this angst is two publications, a press article in Science Daily about Professor Marshall's "study" (which is no study but simply an opinion) in BioEssays. Dr. Trevor Marshall has two degrees, both in electrical engineering. Before I begin, I want to again remind you that I am a psychiatrist who works at a state mental hospital. In my duty to full disclosure, I must say that I have known a lot of psychiatrists in my life and a few electrical engineers. If I knew nothing else of a disagreement between two people but their professions, I would believe the electrical engineer, not the psychiatrist.

In reading his two articles, Dr. Marshall's main hypotheses are simple. (1) Vitamin D from sunlight is different than vitamin D from supplements. (2) Vitamin D is immunosuppressive and the low blood levels of vitamin D found in many chronic diseases are the result of the disease and not the cause. (3) Taking vitamin D will harm you, that is, vitamin D will make many diseases worse, not better. If you read his blog, you discover that the essence of the Marshall protocol is: "An angiotensin II receptor blocker medication, Benicar, is taken, and sunlight, bright lights and foods and supplements with vitamin D are diligently avoided. This enables the body's immune system, with the help of small doses of antibiotics, to destroy the intracellular bacteria. It can take approximately one to three years to destroy all the bacteria." That is, Dr. Marshall has his "patients" become very vitamin D deficient.

Again, Dr. Marshall conducted no experiment and published no study. He wrote an essay. He presented no evidence for his first hypothesis (sunlight's vitamin D is different than supplements). From all that we know, cholecalciferol is cholecalciferol, regardless if it is made in the skin or put in the mouth. His second hypothesis is certainly possible and that is why all scientists who do association studies warn readers that they don't know what is causing what. Certainly, when low levels of vitamin D are found in certain disease states, it is possible that the low levels are the result, and not the cause, of the disease. Take patients with severe dementia bedridden in a nursing home. At least some of their low 25(OH)D levels are likely the result of confinement and lack of outdoor activity. However, did dementia cause the low vitamin D levels or did low 25 (OH)D contribute to the dementia? One way to look at that question is to look at early dementia, before the patient is placed in a nursing home. On the first day an older patient walks into a neurology clinic, before being confined to a nursing home, what is the relationship between vitamin D levels and dementia? The answer is clear, the lower your 25(OH)D levels the worse your cognition.

Wilkins CH, Sheline YI, Roe CM, Birge SJ, Morris JC. Vitamin D deficiency is associated with low mood and worse cognitive performance in older adults. Am J Geriatr Psychiatry. 2006 Dec;14(12):1032-40.

Przybelski RJ, Binkley NC. Is vitamin D important for preserving cognition? A positive correlation of serum 25-hydroxyvitamin D concentration with cognitive function. Arch Biochem Biophys. 2007 Apr 15;460(2):202-5. Epub 2007 Jan 8.


These studies suggest that the low 25(OH)D levels are contributing to the dementia but do not prove it. Only a randomized controlled trial will definitively answer the question, a trial that has not been done. So you will have to decide if vitamin D is good for your brain or not. Dr. Marshall seems to be saying demented patients should lower their 25(OH)D levels. Keep in mind, an entire chapter in Feldman's textbook is devoted to the ill effects low vitamin D levels have on brain function.

Brachet P, et al. Vitamin D, a neuroactive hormone: from brain development to pathological disorders. In Feldman D., Pike JW, Glorieux FH, eds. Vitamin D. San Diego : Elsevier, 2005.

It is true that in some diseases, high doses of vitamin D may be harmful. For example, in the early part of last century, the AMA specifically excluded pulmonary TB from the list of TB infections that ultraviolet light helps. They did so because many of the early pioneers of solariums reported that acutely high doses of sunlight caused some patients with severe pulmonary TB to bleed to death. Thus, these pioneers developed very conservative sun exposure regimes for pulmonary TB patients in which small areas of the skin were progressively exposed to longer and longer periods of sunlight. Using this method, sunlight helped pulmonary TB, often to the point of a cure. Furthermore, it is well known that sunlight can cause high blood calcium in patients with sarcoidosis. In fact, sarcoidosis is one of several granulomatous diseases with vitamin D hypersensitivity where the body loses its ability to regulate activated vitamin D production, causing hypercalcemia.

Cronin CC, et al. Precipitation of hypercalcaemia in sarcoidosis by foreign sun holidays: report of four cases. Postgrad Med J. 1990 Apr;66(774):307-9.

Furthermore, although medical science is not yet convinced, some common autoimmune diseases may have an infectious etiology. I recently spoke at length with a rheumatologist who suffers from swollen and painful joints whenever he sunbathes or takes high doses of vitamin D. As long as he limits his vitamin D input his joints are better. To the extent vitamin D upregulates naturally occurring antibiotics of innate immunity, sunlight or vitamin D supplements may cause the battlefield (the joints) to become hot spots. I know of no evidence this is the case but it is certainly possible.

However, If Dr. Marshall's principal hypothesis is correct, that low vitamin D levels are the result of disease, then he is saying that cancer causes low vitamin D levels, not the other way around. The problem is that Professor Joanne Lappe directly disproved that theory in a randomized controlled trial when she found that baseline vitamin D levels were strong and independent predictors of who would get cancer in the future. The lower your levels, the higher the risk. Furthermore, increasing baseline levels from 31 to 38 ng/ml reduced incident cancers by more than 60% over a four year period. Therefore, advising patients to become vitamin D deficient, as the Marshall protocol clearly does, will cause some patients to die from cancer.

Lappe JM, Travers-Gustafson D, Davies KM, Recker RR, Heaney RP. Vitamin D and calcium supplementation reduces cancer risk: results of a randomized trial. Am J Clin Nutr. 2007 Jun;85(6):1586-91.

I will not write again about Dr. Marshall's theories. No one in the vitamin D field takes him seriously. Personally, I admire anyone willing to swim against the tide and raise alternative theories. I have done the same with influenza and autism. However, I agree with the New York Times, An Oldie Vies for Nutrient of the Decade and Jane Brody's conclusion, "In the end, you will have to decide for yourself how much of this vital nutrient to consume each and every day and how to obtain it." I agree. You will have to decide for yourself.

Breaking news from the American College of Cardiology meetings

The American Heart Association (AHA) was kind enough to send me an e-mail headlining the breaking news from the American College of Cardiology (ACC) meetings underway in Chicago:


ISAR-REACT 3
A Randomized, Double-Blind, Active-Controlled, Multi-Center Trial (ISAR-REACT 3) of Bivalirudin Versus Unfractionated Heparin in Troponin-Negative Patients Undergoing Percutaneous Coronary Interventions After Pre-Treatment With 600 mg of Clopidogrel

TRITON - TIMI 38 Stent Analysis
Prasugrel Compared to Clopidogrel in Patients With Acute Coronary Syndromes Undergoing PCI With Stenting: The TRITON - TIMI 38 Stent Analysis

Percutaneous Coronary Interventions in Facilities without On-Site Cardiac Surgery (NCDR)

(And four other similar reports)


Let's meld the ACC headlines with the financial headlines:

July 2, 2007
The Medicines Company announces reacquisition of all marketing rights to bivalirudin, anticoagulant growing in use for coronary angioplasty and related procedures. 2008 sales anticipated to be in the $15-20 million range, to grow to $90-110 million, a growth rate of 50% per year.


November 20, 2007
Drug manufacturing giant, Eli Lilly, vies for a portion of the $5 billion (annual revenues) oral anti-platelet market, now occupied by Plavix, with its newer, but questionably better, agent, prasugrel.


Growth of the coronary angioplasty (percutaneous coronary intervention, or PCI) doesn't ordinarily make headlines, but the performance of specific companies within the industry does. Angioplasty and cardiac device maker (inc. the drug-coated stent, Taxus), Boston Scientific, for instance, announced record sales of $8.537 billion for 2007, an increase of $536 million. How to grow this market? We could always hope for more people with heart attacks or other unstable symptoms. Or, we could . . . increase the number of hospitals capable of PCI! Brilliant.


The money behind this push for procedures is staggering. It drives enormous marketing efforts, pays Washington lobbyists, pays for many nice dinners and trips for doctors who engage in the system, and pays for very costly research.

And the AHA and ACC are kind enough to let us know about these great pieces of news.

Why health care costs are ballooning

Have you ever wondered to what degree health care is driven by a profit motive?

A doctor advises you to undergo a procedure. Is that advice motivated solely by concern for your health and welfare? Or, does the generous financial compensation peculiar to procedures bias your doctor’s decision?

The billboard on the highway advertises a hospital heart program. Is it meant to raise awareness of lifesaving services? Or, is it the same as an ad for a casino or hotel chain, a marketing tool for generating business?

At one time or another, we’ve probably all shared a suspicion that healthcare is occasionally motivated by money: over-priced prescription drugs, hospitals charging higher prices to the uninsured, the three-minute doctor’s visit for $200.

Direct-to-consumer drug advertising has brought aggressive drug sales tactics front and center to the public’s attention. “Ask your doctor about . . .” is the mantra of countless 30-second spots appearing several times an hour on national television. Direct-to-consumer drug advertising has provided the American public with a $4.5 billion reminder that there’s money to be made in the world of prescription drugs (U.S. Government Accountability Office). And there’s certainly a load of money to be made. A 2003 Harvard and Massachusetts Institute of Technology study showed that, of every dollar spent on consumer drug advertising, $4.20 was recovered through increased sales (Impact of Direct-to-Consumer Advertising on Prescription Drug Spending; Henry J Kaiser Family Foundation). A $53,000 ad run three times during the Oprah Winfrey Show is money well invested for a drug manufacturer.

The knotty issue of medical errors has recently captured attention. Unintentional medical errors—-nurses administering the wrong medication, doctor misdiagnoses or amputating the wrong leg, unrecognized medication interactions—-are an estimated $29 billion headache. Former Secretary of Health and Human Services, Tommy Thompson, reported that up to 98,000 lives are lost every year as a result of errors in healthcare delivery.

No doubt, these are all enormous problems that plague our healthcare system.

But I am going to make the case for a much larger problem. The magnitude of this problem dwarfs that of medical errors. It’s not an issue of neglect, nor is it committed in error. It is built on intentionally committed acts, systematically conducted on a massive scale, and sustained by the participation of many. It is a plague of unprecedented proportions on the health care system. It requires the willing participation of parties at multiple levels, from lone medical practitioners, to hospitals, to multi-billion dollar medical device and drug manufacturers, even to institutions like the FDA and American Heart Association.

The problem is the bizarre situation that has evolved in health care for the heart. I specify health care for the heart, not heart disease, because actual disease is not always part of the equation. Astonishingly, much of the inflated cost of heart care is based on the feared specter of heart disease, the implied threat of heart disease, the possibility, sometimes vanishingly remote, of heart disease based on some harbinger of risk. Sometimes the disease itself is nowhere in sight.

The system thrives on a culture of fear, an open ticket to over-testing and profligate spending. Ads cleverly admonish you to “Do it for your family”. Nuclear stress testing alone generates $18 billion of costs. Yet this test is normal in 80% of people tested. Worse, the 20% of “abnormal” stress test results are not always indicative of genuine disease, they are “false positive,” and are a big part of the reason that 30% of heart catheterizations fail to show disease. “My arteries checked out okay!” relieved patients will declare?-but there may have been no reason to have pursued a costly test like catheterization in the first place. But the system makes far better sense when you understand that nuclear stress tests and heart catheterizations are the bread and butter of cardiologists and hospitals, and the ticket to more financially rewarding procedures.

This approach evolved in the 1960s, when coronary heart disease itself was impossibly difficult to diagnose until a catastrophe like heart attack declared itself. But in the 21st century, coronary heart disease is easily, inexpensively, and safely detectable, decades before heart attack risk looms over your life. Yet murky, risk-based tests like stress tests and cholesterol testing continue to dominate the practice of “heart disease detection” in real-life practice.

Make no mistake: This problem is huge. The cardiovascular health care system has mushroomed into a gargantuan profit-generating mechanism, far larger than is required to deliver essential heart care. In 2003, over $431.8 billion was spent in the U.S. on cardiovascular health care, $151.6 of this on coronary disease alone (American Heart Association, Heart Disease and Stroke Statistics—2007 Update). The U.S. Department of Health and Human Services projects that total health care spending will double to $3.6 trillion by 2014, consuming 18.7 percent of the nation's economy, much of the increase due to expanding cardiovascular costs.

Most tragically, the system has grown through the exploitation of trust. The faith we have in doctors, hospitals, and the institutions and people associated with healthcare has been subverted into the service of profit. Many practitioners and institutions have chosen to operate under the guise of doing good but instead capitalize on the public’s willingness to accept as fact the need for a major heart procedure and all its associated costly trappings.

Heart scans know no race

The New England Journal of Medicine just published a new analysis of the Multi-Ethnic Study of Atherosclerosis (MESA) database authored by Dr. Robert Detrano of University of California-Irvine.

As we would expect, the study confirmed the ability of heart scans and coronary calcium scoring to predict heart attack. This study is unique, hovever, in including Hispanics, Chinese Americans, and African Americans in its 6722 participants.

The analysis confirmed that coronary calcium scores yielded similar information, regardless of race. It confirmed that people with a zero heart scan score had a nearly zero risk of cardiovascular events; it also confirmed that higher scores (e.g., >300) yielded much greater risk over the 4 years of observation: 7.73-fold greater risk for people with scores 101-300; 9.67-fold greater for scores >300.

One of the media reports on the study can be viewed on HeartWire

Bill Sardi's Knowledge of Health website and blog also has an insightful commentary.

To those of us who have used heart scans in thousands of people, the MESA results come as no surprise, having seen these phenomena played out every day in real life. Although similar results have been previously shown in a number of other smaller studies, Detrano's analysis of MESA does serve to further validate these concepts. It also serves to deliver the message more broadly into the mainstream media message.

No surprise whatsoever: Coronary calcium scores obtained through heart scans represent a measure of the disease--coronary atherosclerosis--itself. It is not a risk factor that may or may not be associated with development of coronary atherosclerosis. Thus, when heart scan scores are held up in comparison the cholesterol, LDL cholesterol, c-reactive protein, or any other risk measure, heart scan scores outshine all these measures by enormous margins as predictors of your future.

Want to know what your uncorrected heart disease future could be? Consult your heart scan score. Not your cholesterol panel.

Heart Scan Frustration

Ideally, you get a heart scan and your doctor sits down with you and provides a rational, insightful discussion on what the results mean.

Is heart attack in your future? If so, when? Are blockages present? What is the role of other tests like stress tests and heart catheterizations? Do CT coronary angiograms add any important information? What is the role of cholesterol? Can diet or nutritional supplements impact on heart scan score?

But what happens if you are unable to get the answers you desire? What if you get brusque responses, or your doctor just doesn't know? Or what if there is a clear conflict of interest or the possibility of financially-tainted advice? ("You need a heart catheterization right away or you'll die of a heart attack!")

One example of this process was posted by a frustrated Member of Track Your Plaque who found that answers were virtually unobtainable from his/her doctors:

I underwent a heart scan a few weeks ago, based on a recommendation from a doctor. I assumed that, since I was paying for it, and I requested it, the results would be fully explained to me.

Late on a Friday afternoon, the radiologist who intrepreted it called me and said I would be receiving a report, and so would the doctor. I asked that she explain them to me. She said their policy was to give the report to the doctor and let him explain them. She did say I was in the 90th percentile for my age--and that 10% had a worse score. I asked where do we go from here, and she said, if you're not having symptoms, maybe lifestyle changes, but YOUR DOCTOR will let you know. I asked for a copy of the films and reports, and was told YOUR DOCTOR can request them. I called back a little later and she was gone. It was starting to sink in that I must have a terrible score. In the meantime, I did what I should have done before I went for the scan---looked up information on the internet, and read about calcium scoring. This website [Track Your Plaque] hadn't showed up in my Google search, so a lot of the information was useless.

I did manage to get the score of 186, with the breakdown per artery from someone at the clinic, but only after I insisted I paid for the test, I have a right to the information. 'Course having a score per artery didn't really help---what did it mean? ie: if a 72, how did that correlate to any blockages? Was it a big lump...or spread along the wall throughout the artery.

I had an appt. the following Tuesday with THE DOCTOR---a very busy doctor. After an hour and 1/2 wait in a crowded waiting room, I got to see him. We discussed briefly another issue, and he started walking out. I followed him out and said I wanted my full l5 minutes of time allotted in their scheduling, which seemed to irritate him.

I followed him into his office and said, WHAT ABOUT THE HEART SCAN? What do the numbers mean? He responded that he didn't know, he'd have to see the films, but don't worry--you're probably ok, and I should get a thallium stress test anyway. He said he couldn't intrepret the numbers, or give an opinion on where the plaque was or how it was configured.

I then went to the interventional cardiologist that afternoon and the thallium stress test was scheduled. I asked about the HEART SCAN, and again, no acknowledgment. I asked if he would get the films and explain the results, and again no acknowledment as he was walking out the door.

After this lengthy saga.....MY QUESTION IS....since this is a test you can order yourself (literature at center made mention of the tests you can get without a doctors request)......WHO IS THEIR FIDUCIARY RESPONSIBILITY TO WHEN IT COMES TO EXPLAINING THE RESULTS?

I learned more on this website [Track Your Plaque], and the emailed book then I did dealing with two doctors and the center itself. Thinking back, there was nothing but a brochure on the test at the center. No "Track your Plaque" stuff.




Day 2
I called the scanning center and relayed my dilemma. I was put in touch with another radiologist--a very informative one, who appeared passionate about heart scans as a preventive test. He compared them to mammograms. He hadn't heard about the "Track Your Plaque" program but was going to check it out. He said people varied in their responses to the test results, as well as doctors/cardiologists as to the next step. (ie: lifestyle changes..the next test, etc). He seemed to feel blockages of more than 50% for many cardiologists would indicated angioplasty and stenting.

I'm going back to review the films with him later this week. He wasn't that concerned with the 101 reading on the right artery. The 72 on the left he had concerns with and indicated the CAT test [CT angiography] would offer more as far as how much was there, and approx. blockage, and could be a baseline to compare to in the future. He said some cardiologists would go right to angioplasty...some to a CAT which is more conservative...some might watch and encourage lifestyle changes. He said the Heart Scan doesn't show soft plaque. He also said the internist who referred me was one of only a few in the city that felt strongly about the heart scan---and probably used it to take further action via a referral, and just didn't have time to discuss it, with the way medicine is run these days.



This Member's frustrated post pretty much sums it up:

1) Doctors don't seem to have the time nor motivation to be bothered about offering advice that leads to prevention of disease.

2) The tendency is to always ask, "Are heart procedures necessary?", not "How did this happen?" or "What can we do about this to keep it from getting worse?" How about diet, supplements, and other tools to use at home?

The obvious uneasiness of the radiologist, the last physician this Member spoke with, can just as easily lead to boneheaded advice: Maybe getting a stent isn't such a bad idea. Maybe a CT angiogram is an absolute necessity.

I hear comments like this every day. It is the reason why I continue to plug away at this program and try to set things straight.

By the way, subscribers to our Track Your Plaque Newsletter just heard about our latest success story, Roy, who dropped his heart scan score over 500 points. If you are yet not a newsletter subscriber, click here.

Dr. Nieca Goldberg and heart healthy


In January, 2007, $11.6 billion (2006 net sales) cereal manufacturing giant General Mills rolled out three million boxes of Wheat Chex and Multi-Bran Chex, each boasting a picture of cardiologist, Dr. Nieca Goldberg's face on the box.

Dr. Goldberg has been a frequent national spokeswoman for the American Heart Association (AHA). In a media interview, American Heart Association President, Dr. Alice Jacobs, stated that she supports Dr. Goldberg's work with the General Mills’ products. "The AHA is always in favor of educating the public on how to make heart-healthy lifestyle choices." Dr. Jacobs added that the AHA doesn't consider Goldberg's appearance on the cereal boxes ‘an endorsement’ of the products. "The content on the box is basic heart health information," she said.

Putting images of someone like Dr. Goldberg on cereal boxes appeals to a certain audience, mothers worried about health in this instance. Manufacturers recognize that the perceptions of their food need to be created and nurtured.

Eerily reminiscent of tobacco company tactics of the 20th century? Recall the Brown and Williamson claim that Kool cigarettes keep the head clear and provide extra protection against colds? Lucky Strike, Chesterfield, and Camels all promoted the health benefits of cigarettes, including prominent endorsements by physicians.

How about Philip Morris’ ads for Virginia Slims cigarettes: "You've come a long way, baby"? Interestingly, food manufacturing behemoths Kraft and Nabisco were both majority-owned by Philip Morris, now renamed Altria.

Take a look at the composition of these two "heart healthy" breakfast cereals endorsed by Dr. Nieca Goldberg and the American Heart Association:



























Products like this:

--Make people fat--abdominal fat (wheat belly)
--Reduce HDL cholesterol
--Raise triglycerides
--Dramatically increase small LDL
--Increase inflammatory responses
--Increase blood pressure
--Increase likelihood of diabetes

These products are sugar and sugar-equivalents with a little fiber thrown in and a lot of marketing propaganda, aided and abetted by the misguided antics of the American Heart Association and Dr. Goldberg. It's hard to believe that Dr. Goldberg would sell her soul on something so knuckleheaded for a moment of notoriety.

As I've often said, if a product bears the AHA Check Mark of approval, be sure not to buy it.
