The processed food battlefield

If you have any remaining doubts that the processed food industry is a cutthroat, go-for-the-jugular, organized effort to extract every possible penny from your pocket, even at the expense of health, take a gander at a quote from Marion Nestle's wonderful book, Food Politics.

In Nestle's description on how food conglomerate, Archer Daniels Midland (ADM), conspired to fix prices on some basic agricultural compounds, she quotes an ADM executive captured on videotape and presented in court:

"We have a saying at this company . . . our competitors are our friends and our customers are our enemies."

In other words, ADM's competitors help establish what prices should be charged for basic foodstuffs, while its customers are the ones to do battle with.

Food is a necessary commodity. You and I only need so much of it. So how does a 40 billion dollar food manufacturer extract greater and greater profits and grow their market? Motivate people to eat more. It's that simple.

Eat less? Are you kidding? Eat spinach, green peppers, beets, and other low-margin products? Get real.

Why not take 8 cents worth of wheat flour, add some sugar, food coloring, and some other enticing flavorings like high fructose corn syrup? Put it all in a cleverly illustrated package, maybe even develop an entire story line about the product, complete with clever slogans and songs and . . . ouila! You now have a food that sells for many, many times its intrinsic value.

How to make the health nuts happy? Easy: Add some fiber. Now it's healthy! And it's now part of a "balanced diet".

What if it's full of corn starch, wheat flour, and sugar of the sort that make HDL cholesterols plummet, fan the flames of small LDL, increase inflammatory measures like C-reactive protein, push people closer and closer to diabetes, and make them fat? Then be sure it's low in saturated fat! It might even qualify as "Heart Healthy" by the American Heart Association!

Processed foods have no role in the Track Your Plaque program. If you want to see your CT heart scan score skyrocket, go to your grocery store and stray into the aisles outside of the produce aisle.

But stick to the produce aisle and watch your wallet grow, your health improve, your appetite shrink, all while food processor profits plummet.

Heart Scan debate

A few years back when the book form of Track Your Plaque was first released, I did a bunch of radio and interviews to raise awareness of the book and of CT heart scanning in general.

I'd forgotten about this interview I did for National Public Radio (NPR), in which I debate Dr. Graboys from Harvard. Though I've had this debate countless other times, usually on a less formal basis, I didn't know what to expect at the start of the interview. After all, I knew of Dr. Graboys' reputation as a respected Harvard cardiologist. So I was expecting that at least he would argue that, being relatively new at the time, CT heart scanning was largely unproven in large clinical trials. (This was not entirely true then, however, as at least 1000 trials had already been performed, many of them involving thousands of participants. However, despite that much validation, the concept of CT heart scanning had still not entered the consciousness of most practicing physicians. After all, heart scanning is not part of the "crash and repair" equation that most have invested their career in.)

Heart Hawk re-discovered the debate, still on the NPR website. So here it is. When I re-listened to the debate, I was surprised at how little Dr. Graboys had to offer. He argues that examining left ventricular function should suffice as an important measure of mortality. In other words, if you have experienced a drop in the strength of heart muscle, that can be used to stratify your risk of death.

I tried to convey to the audience (NOT convince Dr. Graboys to believe, as most of my colleagues are stubbornly adherent to their way of thinking until someone tosses a big carrot in front of them) that CT heart scanning provides a means to detect coronary atherosclerosis years, even decades, before questions of mortality (death) became necessary. Heart scanning identifies disease in its early stages so that a program of prevention can be followed and tracked.

Dr. Graboys expressed concern that heart scanning devices could be mis-used to increase hospital procedures. He's absolutely right here. By that same line of thinking, say your crooked auto mechanic on the corner scams most of his customers by doing unnecessary car repairs. Does this mean that we should ban all auto mechanics from repairing cars? I hope not. I believe it does mean that we should all be educated on distinguishing scams from an honest businessman.

Same with heart scans. The key is not to ban heart scanning. We should try to educate the public and physicians to prevent these sorts of scams and decisions based on ignorance from occurring.

Nonetheless, make your own judgments.

Break the addiction

"But, doc, I can't lose my cereal! Pretzels--you've got to be kidding me! I eat 'em every night! I can't do it. I'll be hungry all the time!"

This is a discussion I have every day. The usual suspect: A 50-some year old with HDL in the 30s or 40s, small LDL, borderline high blood sugar approaching the pre-diabetic cut-off, highish blood pressure, excess tummy. They usually struggle with energy, feelings of sleepiness, use lots of caffeine to stay alert even in the middle of the day after a sufficient night's sleep.

Not as obvious as the tremulous, pinopint-pupil drug addict, but I recognize it nonetheless: The processed food addict.

Breaking this addiction can be as difficult for some people as breaking a smoking addiction. Instead of nicotine cravings, they get insatiable hunger. Just 3 or 4 hours without their processed food "fix," and they are ravenous to satiate their impulse. Most give in and go right back to the vicious cycle.

But break the cycle--eliminate processed foods like breakfast cereals, whole wheat crackers, pretzels, cookies, granola bars, fruit drinks, low-fat salad dressings, bran muffins . . .70+% of the foods in your supermarket---and you will make an interesting discovery:

You no longer crave these foods.

Just think about it: The addictive properties of processed foods are a food manufacturer's dream. What other product besides cigarettes has an addictive quality that ensures you come back for more... and more and more.

It it just too creepy that much of the processed food industry is, in reality, owned by the tobacco industry (Altria, previously known as Phillip Morris) and RJ Reynolds. Perhaps that is the modus operandi of these corporations: Identify products that have an edge, foods or other products that possess an addictive quality. This is not true of cucumbers, for instance. What a lousy investment a cucumber grower would make!

Be smarter than Phillip Morris. Outsmart the people looking to empty your pocket and corrupt your health. Break the addiction.

Hang around the produce aisle of your grocery and use the farmer's market or your local equivalent. Look for locally grown foods. Try to keep your food as unprocessed as possible.

You will be impressed with the results.

Are we done here?

Les' doctor consulted me because his CT heart scan score had increased 40% from 893 to 1259 over 18 months.

Judging by his appearance, Les was a 59-year old guy trapped somewhere in the 1980s. The only reason he'd undergone two heart scans was from the prompting of his wife, who was quite savvy.

Among the steps we took was to have Les undergo a stress test. I explained to Les and his wife that stress tests are effective tests of coronary blood flow, but not of plaque. Therefore, there was somewhere around a 25-35% likelihood of an abnormality that suggested poor flow in one or more portions of the heart.

Les passed his stress test easily. A bricklayer, Les was accustomed to heavy physical effort. "Are we done here, doc?" Les asked. Les' wife raised her eyebrows but, to her credit, kept quiet. She'd obviously been here before.

I explained to Les that having normal coronary blood flow was just one aspect of the issue.

"But I don't need a stent, right? I don't need a bypass. I already take Vytorin. So I need a cheeseburger once in a while. So what! Who doesn't? What else is there?"

I continued. "Les, with a normal stress test, there's no denying you still have lots of plaque in your heart's arteries. The risk to you is that one of these plaques will 'rupture,' sort of like a little volcano erupting. Of course, it's not lava that flies out, but the internal contents of plaque. When that happens and the contents of plaque get exposed to blood flowing by, a blood clot forms. That's a heart attack.

"With a 40% increase in your score over 18 months, you are, in fact, at substantial risk for such a plaque rupture. Unless you're fond of hospitals and the thought of heart procedures, then we need to address that part of the issue."

So it went. Step by step, with the quiet, strong support of Les' wife, we uncovered 7 additional causes of his heart disease. It wasn't the easiest process for us, but we did manage to educate Les on the simple steps he needed to take to 1) correct the causes of his coronary plaque, 2) how to use foods and stop fanning the flames of his plaque, and 3) how to live with this nasty specter hanging over him.

Now, if we could only transform Les into an optimist . . .

Wheat belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

If health won't motivate them, maybe money will

As part of our ongoing effort to educate everyone about the value of heart scans and how they can serve to start a program of heart disease prevention (or elimination), we occasionally distribute press releases on one facet of this discussion or another.

Here's the one we released on our Cost Calculator, the one we developed that showed that $20 billion would be saved annually just by applying the program to men, ages 40-59.




Accurate Detection and Prevention of Heart Disease Can Reduce Healthcare Costs, According to New Cost Analysis

A new cost analysis developed by cardiologist Dr. William Davis and his colleagues suggests that healthcare costs can be reduced by billions of dollars with the application of a simple program for heart disease detection and prevention.

Milwaukee, WI (PRWEB) July 23, 2007 -- Billions of dollars in healthcare could be saved every year by applying a simple program of heart disease detection and prevention on a wide scale in the U.S., suggests a new cost analysis developed by cardiologist Dr. William Davis and colleagues. Davis and his colleagues are the developers of the Track Your Plaque program for heart disease detection and prevention.

In the next 24 hours, 10,000 major heart procedures will be performed in hospitals across the U.S. The tab for this bill will top $400 billion in 2007 alone, nearly twice the sum spent on the war on cancer.

As costs escalate at an alarming rate, tools for prevention of disease are also advancing. While drugs like Lipitor® make headlines and dominate direct-to-consumer TV ads, a quiet revolution is taking place among physicians and the public eager to find better answers, some of which also pose opportunities for stretching the healthcare dollar.

“We’re essentially throwing away billions of dollars each and every year by ignoring the savings power of preventive strategies for heart disease,” proclaims Davis, a Milwaukee cardiologist. Davis is author of several books on heart disease detection and prevention, has been a vocal advocate for preventive strategies and is founder of www.cureality.com.

Davis and his colleagues developed a cost model to predict how much money could be saved by the adoption of new preventive strategies on a broad scale in the U.S. “The cost savings are startling. If males in the 40–59-year-old age group, for instance, were to undergo a simple CT heart scan for early detection of coronary heart disease, followed by a purposeful yet focused program of prevention using widely available tools, our cost model shows that we would save the American public over $20 billion annually. Extending this calculation to the broader population would multiply savings several-fold.”

Heart care is already the single largest healthcare category in the U.S. As costs go up by double-digit percentages, fewer people can afford healthcare. Those who can afford it spend an increasingly greater portion of their disposable income to maintain it. The Agency for Healthcare Research and Quality predicts that, at the current rate of growth, healthcare costs will balloon to absorb 20 percent of American Gross Domestic Product (GDP), about $4 trillion, in the next 10 years.

Davis points out that reducing the annual U.S. expenditure for heart disease by 20 to 30 percent could save between $80 and $120 billion each year. That marginal savings exceeds the sum the U.S. spends on the domestic war on terror.

Davis and his group have dubbed the conventional procedure-based approach to heart disease management the “crash and repair model” because of its focus on urgent procedural intervention that takes place in hospitals.

The crash and repair model is costly. According to the American Heart Association, a heart catheterization (performed 3,553 times per day, seven days a week) costs an average of $24,893; a coronary bypass operation (performed 1,170 times every day, seven days a week) costs an average of $67,823 (hospital costs, 2004, the latest year for which data are available). These figures don’t incorporate long-term costs incurred in the years following the procedure or time lost from work.

The relatively high payment to physicians and hospitals for performing high-tech heart procedures provides a disincentive to redirect patients to a less costly prevention model. The exceptional costs of high-tech, high-ticket heart procedures would become increasingly unnecessary if better heart disease preventive practices were delivered on a broad scale. “Like seatbelts, preventive measures for heart disease are more cost effective and extract a far lower toll in human suffering than the ‘crash and repair’ approach. Our cost calculations bear out the enormous savings possible. In fact, all of the tools necessary to deliver a method of early heart disease detection and prevention are already available throughout the U.S. We’ve just got to encourage physicians and the public to take advantage of them.”

Track Your Plaque is an informational and educational Web site devoted to showing people how CT heart scans can be used as a starting point for a program of heart disease prevention and reversal.

What role calcium supplements?

A frequent question in the Track Your Plaque program is whether taking calcium supplements to reduce risk for osteoporosis adds to calcium in arteries and raises CT heart scan scores.

No, calcium supplementation does not add to coronary calcium. Thankfully, there is some wisdom to calcium metabolism. Calcium deposition or resorption is under independent local control in bone, as it is in the artery wall. Taking calcium has no effect on calcium deposition in your coronary arteries.

However, there's a lot more to it. Taking calcium has only a modest effect on bone health. Most women can only hope to slow or stop calcium loss from bone by taking calcium supplements. Calcium supplements do not increase bone calcium. The reason why calcium supplementation works at all is, when calcium is absorbed into the blood, it provides a feedback signal to the parathyroid gland to shut down parathyroid hormone production, the hormone responsible for extracting calcium from bone. But the calcium itself does not end up deposited in bone.

Likewise, calcium supplements have essentially no effect on the artery wall. But vitamin D controls calcium absorption and, curiously, appears to exert a dramatic effect on calcium depostion in coronary arteries. In fact, I would credit vitamin D as among the most important factors in regulating arterial health that I've encountered in a long time.

Thus, bone health and arterial health do indeed intersect via calcium, but not through calcium supplements. Instead, the control exerted by vitamin D connects the seemingly unconnected processes.

Vitamin K2 provides another unexpected juxtaposition of the two processes. Deficiency of K2, which is proving to be a lot more common than previously thought, permits an enzyme in bone to exert unrestrained calcium extraction. Deficiency of K2 in artery walls allow another enzyme to deposit calcium and grow plaque without restraint. Yet another intersection between bone health and coronary health that involves calcium, but as a passive participant.

Stay tuned for a comprehensive Track Your Plaque Special Report on these topics coming in the next couple of weeks. I'm very excited about the emerging appreciation of calcium as an active ingredient in plaque, not a dumb, passive marker as previously thought. Vitamins D3 and K2 are among the keys to this phenomenon.

"Heart scans" are not always heart scans

Beware of the media reports now being issued that warn that "CT heart scans" pose a risk for cancer.

One report can be viewed at
http://www.webmd.com/cancer/news/20070717/ct-heart-scan-radiation-cancer-risk.

This was triggered by a Columbia University study of risk for cancer based on the dose of radiation used in CT coronary angiograms. Theoretically, exposure to the radiation dose of CT coronary angiography can raise risk for cancer by 1 in 143 women if radiated in their 20s just from that single exposure.

If you've been following the Track Your Plaque discussion, as well as my diatribes in the Heart Scan Blog, you know that the media got it all wrong. The "heart scans" they are referring to are not the same as the heart scans that we discuss for the Track Your Plaque program.

A conventional heart scan (of the sort we refer to) exposes the recipient to 4 chest x-rays of radiation if an EBT device is used, around 8-10 chest x-rays of radiation if a 64-slice CT scanner is used. For the quality of information we obtain from these screening heart scans, we feel that it's an acceptable exposure.

The "heart scan" this study and subsequent reports refer to is not truly a screening heart scan, but a CT coronary angiogram, or CTA. CTAs are performed on the same CT or EBT devices, but involve far more radiation. CTA exposes the recipient to about 100 chest x-rays of radiation on a 64-slice device (more or less, depending on the way it is performed.) Just a couple of years ago, some centers were performing CTA on 16-slice devices, a practice I and the Track Your Plaque program vocally opposed, since up to 400 chest-rays of radiation were required! I even called a number of centers advising them that they were putting the public in jeopardy. CTAs also require injection of x-ray dye, just like any conventional angiogram.

CTA on 64-slice CT scanners require the same radiation exposure as a conventional heart catheterization, an issue glossed over in most conversations. In other words, the test that many of my colleageus so casually recommend poses a similar risk.

The message: the test I advocate for screening for coronary heart disease is a CT or EBT heart scan, not a CT coronary angiogram. CTA is a useful test and will get better and better as the engineers discover ways to reduce radiation exposure. But, in 2007, CTA is a diagnostic device, not a screening device. If you require an abdominal CT scan because your doctor suspects pancreatic cancer, or a CT scan of the brain because you might have a life-threatening aneurysm causing double-vision or seizures, it would be silly to not undergo the scan because of long-term and theoretical cancer risk.

But undergoing a CT coronary angiogram for screening purposes is ridiculous with present technology. I've said it before and I will say it--shout it--again:

CT coronary angiograms are not screening procedures; they are diagnostic procedures that should be taken seriously and do indeed pose measurable risk for cancer, a risk that is presently unacceptable for a screening test.

You wouldn't undergo a mammogram to screen for breast cancer if it exposed you to 100 chest x-rays of radiation, would you? Screening tests should be safe, reliable, accurate, and inexpensive. CT coronary angiography is none of these things. Genuine heart scans--the kind the Track Your Plaque program talks about and relies on--is all of those things.

Heavy traffic and heart scans

A German study just reported in Circulation showed a graded response of EBT heart scan scores and proximity to traffic.

Living 50 meters (around 150 feet) from traffic increased the likelihood of a higher coronary calcium score by 63% compared to those living 200 meters (around 600 feet or two football fields) away from traffic.

A sample news story can be found at http://healthday.com/Article.asp?AID=606431.

The German investigators speculated that either the heightened exposure to exhaust fumes and/or the increased stress triggered by the constant noise might be the culprits behind the phenomenon.

I think the study is interesting in a number of ways from the Track Your Plaque viewpoint:

--Sometimes, there are factors that extend beyond lipoproteins, vitamin D restoration, optimism vs. pessimism, etc. that influence heart scan scoring. Are these factors powerful enough to overcome the adverse effects of traffic or other environmental effects? Can your proximity to traffic make or break your heart scan score-controlling efforts? This remains to be established.

--How much of a role does the stress issue play? Is this just a variation of the optimism vs. pessimism theme? I know when I'm in traffic in a car or on a bicycle, it often feels like I am at the mercy of hordes of people in a hurry, the soccer Moms on cell phones, applying makeup and eating, the hormonal teenager, the occasional drunk. Living in the midst of it must be demoralizing, a sense that you are lost in a sea of uncaring humanity stripped of individuality. When I look outside my den window right now, I see the lawn that I cut and water and the flowers and evergreen trees I've planted over the years. It provides a sense of life, belonging, and earth. What if instead I saw anonymous cars buzzing by, dozens of unfamiliar faces every minute, none of which plays any palpable role in my life?

--This simple observation will add to the healthy-consciousness and Green movements, since it is just one more piece of evidence that congestion and urbanization do indeed take their toll. In an obtuse way, I think this is one step closer to increasing disillusionment over the "over-processing" of human experience: processed foods, depersonalization and alienation in neighborhoods and homes, the dissolution of the American family.

Lastly, notice how the conversation about CT (in this case, EBT) heart scanning has seamlessly worked its way into conversation? Just ten years ago, a long-winded explanation would have been required in press reports on just what CT heart scanning was. Now, the information is presented and--well, we all know what heart scanning is, right?

A small study but one that comes at an important time. Good things will come from this one study. It will work its way into discussions about where to locate schools, how to situate homes in relation to heavy traffic, it will help "legitimize" this wonderful tool called heart scanning. How many medical tests beyond blood work can be easily performed in 4500 study participants?

I always like to take some simple observation and see how it fits into developing trends. Few studies or other human-generated experiences by themselves change the world. Instead, it happens in little incremental bits and pieces.

Digging for the truth

I remain continually amazed how difficult it can be to gain an understanding of what is true and what is not true. I am particularly worried about the messages provided by agencies that stand to make enormous gains by persuading us to believe their version of the "truth".

For a moment, let's strip away the charitable covers of some financially-motivated organizations and see what they really look like:


Hospitals: The dream of hospitals is to shift the proportion of patients towards those with the most profitable diseases in well-insured patients. Heart disease is among the best paying diseases. HOSPITALS WANT YOU TO HAVE HEART DISEASE.

Doctors: Many (though not all) want to deal with diseases that pay well. Implanting a stent can pay several thousand dollars. Putting in a defibrillator can likewise pay handsomely, even better than stents. DOCTORS WANT TO STEER YOU TOWARDS PROCEDURES THAT REIMBURSE GENEROUSLY. Talk is cheap and pays poorly. Heart scans? Useless, since they're cheap. CT angiography? Now we're talking! $1800 dollars is a lot more interesting than $200 or so for a simple heart scan. CT angiograms also lead to catheterization, stents, hospitalizations.

Drug manufacturers: The holy grail for drug manufacturers is a chronic condition that is present in large numbers of people. An antibiotic, for instance, is a drug manufacturers waste of time: Short courses of treatment in relatively few people. Cholesterol drugs, blood pressure drugs, drugs to modify personality or some aspect of behavior--these you take for years, decades, or a lifetime, and millions are persuaded they need them. DRUG COMPANIES WANT CHRONIC CONDITIONS (WHETHER OR NOT THEY'RE DISEASES) IN PEOPLE WHO SURVIVE FOR A LONG TIME, NOT SICK PEOPLE.

Supplement manufacturers: What don't we need in the eyes of sellers of nutritional supplement? While a program like Track Your Plaque makes liberal use of supplements in a focused and, I believe, rational way, supplement sellers want you to take dozens or preparations of dubious value: milk thistle, hawthorne, ribose, hoodia, silymarin, hydroxycitric acid . . . Unlike the larger ambitions and bigger money of the pharmaceutical industry, the supplement industry is often driven by the momentary craze and the quick payoff. THE SUPPLEMENT INDUSTRY IS LOOKING FOR SUCKERS.

Food manufacturers: The holy grail for the food industry are foods that have high markups, are convenient (e.g., eaten right out of the box or package), and are purchased repeatedly. Even better, if a health claim can be added, it can ride the current wave of the public's health consciousness. Thus, Cocoa Puffs can be labeled "Heart Healthy". How about foods that have addictive potential and virtually ensure repeat sales? Eat some and you want more within 2-4 hours! As nutritionist Marion Nestle says, the mantra of the foods industry is "Eat More". It is my firm conviction that the epidemic of obesity in the U.S. is not due to laziness, video games, and computers. It is the fault of food manufacturers. FOOD MANUFACTURERS WANT US FAT AND HUNGRY AND WANT US TO STAY THAT WAY. What pays better, a 110 lb vegetarian woman who shops at the farmer's market and buys locally produced foods, or the 260 lb glutenous and always-hungry woman who fills her supermarket shopping cart with 15 cents worth of flour and sugar priced at $4.59 (cleverly disguised as a healthy breakfast cereal), instant mixes, convenient meals, energy bars, and chips?

Government agencies: User fees for the FDA paid by drug companies have caused the FDA to be beholden to drug company pressures. The USDA, charged with crafting the food pyramid, was created to support the farm industry and distributors of their products, not to disseminate public health. The food pyramid is the watered down end result of food industry lobbying and threats, not the scientific advice of nutritionists. GOVERNMENT AGENCIES SERVE INDUSTRY FIRST, THE PUBLIC SECOND.

Health websites: Read popular websites like WebMD for information and the conversation quickly steers towards drugs. "Natural treatments for cholesterol" talks about reducing saturated fat and then gushes about the wonders of statin drugs. Guess where 80% of WebMD's revenues come from? Yup, the drug industry. The same goes for many magazines, TV shows, and other media. MEDIA IS OFTEN THE TOOL OF BIG INDUSTRY.



I'm sounding like a conspiracy theorist. I don't believe that I am, but I am skeptical of the messages we often receive from the media, advertisements, news reports, websites, etc. It's left to you and me to use our judgment and decide what is truth and what is someone's version of a message crafted towards their hidden agenda.

I am hoping that the real truth will grow through a wiki-like phenomena driven and supervised by a collective knowledge that we all contribute towards. That will happen, most likely, on the internet. Just as Wikipedia overtook the revered Encylopedia Britannica in the blink of an eye at far less cost yet with greater depth and equivalent accuracy, so will it happen in health information. I'm uncertain of the eventual form this health-wiki will take, but it will shatter many smug and deeply-entrenched powers that at present continue to profit from mis-information.

A new Track Your Plaque record: 63% reduction

Stress can booby-trap the best efforts at reducing your CT heart scan score.

But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction.

Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record.

I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!

Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!)

The Ornish diet made me fat

I got that kind of question today that tempts me to roll my eyes and say, "Not again!"

"If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease.

I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices.

What happened?

I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day.

Hundreds of my patients suffered similar phenomena.

Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.

So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.

Keep your eyes open for the New Track Your Plaque Diet.

Do lower heart scan scores grow faster?

If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score.

If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points.

This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year.

In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)

If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score.

Mr. Salazar: Check your Lp(a)

Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.

At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending.

Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye.

But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.

I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).

It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.

I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why?

The answer is almost certain to be Lp(a).

Heart Scan Curiosities #8: Fat heart

Here's a curious incidental finding on a heart scan: an unusual fat accumulation around the heart.



The arrows point to an unusually large accumulation of fat tissue on either side of the heart. This man was mildly but not excessively overweight at 5 ft 10 inches and 201 lbs.

I know of no specific implications of this curiosity. It makes me wonder if he was very obese at one time and has since lost the weight.

Chocolate and blood pressure

A recent very detailed and clean study on the effects of a small serving of dark chocolate on blood pressure was just published in the Journal of the American Medical Association.

I was going to do a little Blogging on this interesting study but I read the Fanatic Cook's wonderfully insightful comments. I'd direct you to her discussion, instead: A small daily dose of dark chocalate lowers blood pressure at http://fanaticcook.blogspot.com/. I couldn't have said it any better.

By the way, the authors of the study had no financial ties to the chocolate or cocoa industry. Refreshing.

Does prevention save money?

Prevention and reversal of heart disease are undoubtedly preferable to the current crash and repair model currently followed by doctors and hospital, the model that has created an enormous medical device industry to support it.

But does it save money? This debate often boils down to a metric of "lives saved per $100,000". Thus, the statin drugs (of course) have been subjected to such analyses and have been shown to be "cost-effective."

But how does a powerful heart disease prevention and reversal program like Track Your Plaque compare to the current crash and repair procedural approach to heart disease? This is a very difficult analysis, one that is subject to enormous variation, depending on the population studied and the prevalence of disease, the local practice habits (e.g., in the northwest Cleveland suburb of Lorain, virtually everybody going to the hospital for any heart problem gets one or several heart catheterizations), and other factors.

There's also the difficulty of what should constitute a prevention program. Is it like that used in the COURAGE Trial of "optimal medical therapy" that included nitroglycerin, aspirin, a beta blocker, and statin drug (which we regard as a laughably silly approach), or one like Track Your Plaque in which we try to correct the causes of heart disease, not just palliate (BandAid) them? Costs vary. The "optimal medical therapy" is very costly due to its reliance on medications to treat symptoms. Our program is somewhat costly because of the reliance on a CT heart scan and lipoprotein analysis (though, in the long perspective, our costs are modest).

We asked this question and came up with a lengthy analysis. Bottom line: Following the Track Your Plaque program saves enormous sums of money. Because of the complexity of the analysis, which is theoretical and not a real-world test, we confined our analysis to men in the 40-59 year old age group. If this group alone were to subscribe to a intensive but rational program of prevention like Track Your Plaque, over $20 billion dollars per year would be saved.

If the analysis were extended to women of all ages and men older than 59, the numbers would balloon to many more tens of billions of dollars. Such a savings wouldn't cure the healthcare system's growing financial crisis, but it sure would be a big help. Sort of like converting to a hydrid car--you don't eliminate the need for gas, but you'll save a lot in fuel costs.

The Track Your Plaque approach makes sense because it is, bar none, the most powerful approach to gaining hold of heart disease risk available. But it also makes sense from a financial standpoint. Now, if we can only convince the hospitals, the $30 million annual salary device manufacturer CEO, and my procedure-crazy colleagues that this way makes more sense.

Watch for our analysis on an upcoming Track Your Plaque Special Report.

Where should fiber come from?

Ray had the usual protuberant belly overhanging his beltline of someone who was over-reliant on processed starches, particularly wheat.

After all, he ran a sandwich bakery. He sheepishly admitted that he ate the products of his own production line every day while at work, even bringing a few sandwiches home.

At 5 ft 10 inches, 201 lbs, he wasn't terribly overweight, but all the excess was in his beltline. He had the lipoproteins to match: HDL 38 mg/dl, triglycerides 180 mg/dl, 83% of all LDL particles were small, excess VLDL and IDL. Blood pressure: 140/88. Blood sugar: 112 mg/dl.

With a CT heart scan score of 698, Ray had some work to do.

Among the strategies we discussed was a need to dramatically reduce, perhaps eliminate, wheat products and other high-glycemic index foods.

"You've got to be kidding me!" Besides the inconsistency with his business, he was puzzled on what foods were edible for his pattern. We discussed how he could easily replace his reliance on wheat and breads with more vegetables, more fruits, more lean proteins, and more healthy oils.

"But I won't get any fiber!" he declared. That was why he tried to choose whole wheat bread for his sandwiches.

This is a common concern when we discuss how grains, particuarly wheat, need to be sharply reduced. In the most recent edition of his Paleo Diet Newsletter, Dr. Loren Cordain has laid out a wonderful graph that beautifully illustrates the issue:




(From The Paleo Diet Newsletter at http://www.thepaleodiet.com/newsletter/back_issues.shtml)


In other words, reducing or eliminating "fiber-rich" grains and replacing their calories dramatically increases fiber content of your diet.

For Ray, whose livelihood depends on promoting and perpetuating the use of wheat breads, it will be tough to keep him on the right track. My prediction: the results he will see will be substantial and it will become difficult to return to eating his own products.

There's no doubt that this concept can be economically disruptive for many people, including Ray. It's a tough situation we've created: a huge industrial complex based on growing grains and wheat, processing it into breakfast cereals, bagels, pretzels, crackers, and sandwiches. But it has also contributed to the epidemic of obesity and the patterns that people like Ray have.

But the startling fact remains: If replaced with vegetables and fruits, reducing grains increases the fiber content of your diet, and not jsut a little bit, but enormously. If green peppers and spinach had brand names like "Fiber One" and "Smart Start" along with flashy boxes, then maybe it would be an easier concept to grasp.

The Detection Gap

You've heard of the Generation Gap, the Income Gap, the Technology Gap, the Gender Gap, and the Achievement Gap.

How about the Detection Gap?

Haven't heard of it? That's the gap between coronary heart disease detected by conventional methods widely practiced in the community and the real prevalence of the disease.

The standard approach to coronary heart disease detection is a relatively simple formula. One of three things are sought:

1) Symptoms of heart disease like chest pain or breathlessness.
2) An abnormal EKG or abnormal stress test.
3) A catastrophe like heart attack or sudden cardiac death.

By this equation, the American Heart Association (AHA) estimates that 36% of American men and women have coronary disease.

However, we say the number is more like 48%. That's the number we arrive at when we ask: How many men and women have CT heart scan scores above zero?

The difference is the Detection Gap. Though only around 12%, it amounts to millions of people. The problem is that, by the conventional approach to detection of heart disease, you often don't know you have it until you're lying on a hospital gurney being wheeled off to a major procedure. Or your friends, family or neighbors find your body.

If heart disease is detected by a CT heart scan, it tends to be early, before catastrophe strikes. You can use tools like niacin, vitamin D, flaxseed, etc., all the components of the Track Your Plaque approach.

If heart disease is detected by waiting for the appearance of symptoms, then a stress test (usually nuclear) is followed by a heart catheterization, stents, bypass, etc. So there's more than a Detection Gap. There's also a difference in the sorts of therapies chosen. There's certainly a difference in cost.

In my view, there is no rational reason not to close the Detection Gap. While CT heart scan scores aren't perfect, they're damn close. The Detection Gap could be closed to around 2%. We'd also save billions of dollars.

Apoprotein B on VAP

We've just received an announcement that, if your Vertical Auto Profile lipoprotein test (Atherotech) is provided through the national Quest laboratories (a large national laboratory company), they will include an apoprotein B.

This represents an improvement over the previous "direct LDL," a measured LDL cholesterol. Recall that standard lipid panels obtained in hospitals and doctors' offices is a calculated LDL, based on the 40-some year old Friedewald calculation. In my view, the Friedewald calculated LDL is a dinosaur that is virtually useless and needs to be retired.

Direct, or measured, LDL is a slight improvement. It removes some of the inaccuracy introduced by the assumptions built into the calculated value.

Apoprotein B (also called apoprotein B100) is yet another improvement. Apo B's have been available for years, but was not provided on the VAP. The Atherotech people have done a good job of making VAP more broadly available through "drawing stations" and proponents like Life Extension. Adding an ApoB is a favorable development, since it incorporates the risk of other ApoB-containing particles, like VLDL, IDL, and Lp(a). Several studies like the Quebec Cardiovascular Study have shown that ApoB is a superior predictor of heart disease compared to calculated LDL.

I still believe that the gold standard for assessing risk from an LDL standpoint is the LDL particle number along with the other measures provided by the NMR assay (Liposcience). However, the addition of the ApoB to VAP adds greater confidence to the measures provided by this technique. Those of you who rely on the VAP assay provided by Quest for your Track Your Plaque program for control of CT heart scan scores therefore have access to this improved panel.

Beating the Heart Association diet is child's play



In response to the Heart Scan Blog post, Post-Traumatic Grain Disorder, Anne commented:


While on the American Heart Association diet my lipids peaked in 2003. I even tried the Ornish diet for a short time, but found it impossible.

Total Cholesterol: 201
Triglycerides: 263
HDL: 62
LDL: 86

After I stopped eating gluten (I am very sensitive), my lipid panel improved slightly. This past year I started eating to keep my blood sugar under control by eliminating sugars and other grains. Now this is my most recent lab:

Total Cholesterol: 162
Triglycerides: 80
HDL: 71
LDL: 75


Isn't that great? This is precisely what I see in practice: Elimination of wheat and sugars yields dramatic effects on basic lipids, especially reductions in triglycerides of up to several hundred milligrams, increased HDL, reduced LDL.

Beneath the surface, the effects are even more dramatic: reductions or elimination of small LDL particles, reduction or elimination of triglyceride-containing lipoproteins, elimination of the marker for abnormal post-prandial (after-eating) lipoproteins, IDL, reduced c-reactive protein. Add weight loss from abdominal fat stores and reduced blood pressure.

In fact, I would go so far as to speculate that, if the entire nation were to follow Anne's lead and eliminate wheat and sugars, "need" for 30% of all prescription medications would disappear. The incidence of diabetes would be slashed, the U.S. would no longer lead the world in obesity.

Anne and I are not the first to make this observation. It has also been made in several studies, such as:

The Duke University study of low-carbohydrate diets in type II diabetics. In this study, 50% of low-carb participants became non-diabetic: They were cured.

One of the many studies conducted by University of Connecticut's Dr. Jeff Volek, demonstrating dramatic improvement in glucose, insulin (reduced 50%) and insulin responses, and lipids.

Dr. Ron Krauss' early studies that hinted at this effect, even though the "high-fat" diet wasn't really low-carbohydrate.

If wheat and sugar elimination has been shown to achieve all these fabulous benefits, why hasn't the American Heart Association spoken in favor of this dietary approach and other- low-carbohydrate diets ? Why does the American Heart Association maintain its "Check-Mark" stamp of approval on Cocoa Puffs and Count Chocula cereals?

Victim of Post-Traumatic Grain Disorder

Heart Scan Blog reader, Mike, shared his story with me. He was kind enough to allow me to reprint it here (edited slightly for brevity).



Dr. Davis,

I was much intrigued to stumble onto your blog. Heart disease, nutrition, and wellness are critically important to me, because I’m a type 2 diabetic. I’m 53 and was diagnosed as diabetic about 5 years ago, though I suspect I was either diabetic or pre-diabetic 5 years before that. Even in a metropolitan area it's next-to-impossible to find doctors sympathetic to any approach beyond the standard get-the-A1c-below 6.5, get LDL <100, get your weight and blood pressure normal, and take metformin and statins.

I’m about 5’10-and-a-half and when I was young I had to stuff myself to keep weight on; it was an effort to get to 150 pounds, and as a young man, 165 was the holy grail for me. I always felt I’d look better with an extra 10-15 pounds.
I ate whatever I wanted, mostly junk, I guess, in my younger years.

When I hit about age 35, I put on 30 pounds seemingly overnight. As I moved toward middle age I became concerned with the issue of heart health, and around that time Dr. Ornish came out with his stuff. I was impressed that he’d done a
study that supposedly showed measurable decrease in atherosclerotic plaque, and had published the results of his research in peer-reviewed journals. It looked to me as though he had the evidence; who could argue with that? I tried his plan on and off, but as so many people note, an almost-vegan diet is really tough. It was for me, and I could never do it for any length of time. But given that the “evidence” said that I should, I kept trying, and kept beating up on myself when I failed. And I kept gaining weight. I got to almost 200 pounds by the time I was 40 and have a strong suspicion that that’s what caused my blood sugar to go awry, but my doctor at the time never checked my blood sugar, and as a relatively young and healthy man, I never went in very often.

I’ve had bouts of PSVT [paroxysmal supraventricular tachycardia, a rapid heart rhythm] every now and again since I was 12 or so. I used to convert the rhythm with Valsalva, but as I moved into my forties, occasionally my blood pressure would be elevated and it made me nervous to do the procedure because it was my understanding that it spikes your blood pressure when you do it. So I began going to the ER to have the rhythm converted, which they do quite easily with adenosine. On one of my infrequent runs to the ER to get a bout of PSVT converted, they discovered my blood glucose was 500 mg/dL, and I’d never experienced any symptoms! They put me in the hospital and gave me a shot of insulin, got it town to 80 mg/dL easily,
diagnosed me as diabetic, and put me on 500 mg. metformin a day.

I was able to get my A1c down to 7, then down to 6.6, and about that time I read a number of Dr. Agatston’s books, and began following the diet, and pretty quickly got my A1c down to 6.2, and my weight down, easily, to 158. That was fine with my doctor; he acted as though I was in good shape with those numbers. Soon I ran into Dr. Bernstein’s material, and came face to face with a body of research that suggested I needed to get the A1c down to below 5! That was both discouraging and inspiring, and frankly it’s been difficult for me to eat as lo-carb as I appear to need to, so I swing back and forth between 6.2 and 6.6. I know I need to work harder, be more diligent in my carb control, and I see with my meter that if I eat low-carb I have great postprandial and fasting blood sugars, but since I don’t particularly get any support or encouragement from
either my doctor or my wife for being so “radical,” it’s hard to pass the carbs by.

One thing that always confused me was that though I saw on my meter that BG [blood glucose] readings were better with a lo-carb diet, and though I saw the preliminary research suggesting that lo-carb could be beneficial in controlling CVD, I didn’t understand why Ornish had peer-reviewed research demonstrating reversal of atherosclerosis on a very-lowfat diet. How could two opposing approaches both help? I wondered if it were possible that one diet is good for diabetes, and the
other good for heart health. That would mean diabetics are screwed, because they always seem to end up with heart disease.

From time to time I’d look for material that explained this seeming contradiction. I was determined to try to stay lo-carb, simply because I saw how much better my blood sugars are when I eat lo-carb; but it’s hard in the face of this or that website that tells you about all the dangers of a lo-carb diet and that touts the lo-fat approach. That tends to be the conventional wisdom anyway.

Finally in one of those searches I came across your material, and saw you offer what was at last an explanation of what Ornish had discovered--it wasn’t a reversal of atherosclerotic plaques he was seeing; it was that his diet was improving endothelial dysfunction in people who had had high fat intakes.

Odd as it may seem to you, that little factlet has been enough to allow me to discard entirely the lingering ghost of a suspicion that I ought to be eating very-lowfat. In fact, I was very excited to see your claim that your approach can reverse atherosclerotic plaque.

It would be nice to find a doctor who’d be supportive of your approach. My doctor isn’t much interested in diet or
nutrition. He just wants my weight in the acceptable range, my blood pressure good, and my LDL 100 or below (which I know isn’t low enough). He’s not particularly interested in getting a detailed lipid report. I hope I can talk him into ordering one so that it’s more likely I can get it covered by my insurance.

I very much appreciated the links you gave to Jenny’s diabetes websites, and I’ve resolved to get even better control of my BG by being more diligent with my diet. I’m planning on joining your site, reading your book, and following your advice. I just have this sort of deflating feeling that it would have been better if I’d stumbled upon this before I had diabetes. Still, it’s nice to have a site that offers to laypeople the best knowledge available concerning how to take care of their heart.



Mike is yet another "victim" of the "eat healthy whole grains" national insanity, the Post-Traumatic Grain Disorder, or PTGD. The low-fat dietary mistake has left many victims in its wake, having to deal with the aftermath of corrupt high-carbohydrate diets: diabetes, heart disease, and obesity.

We should all hope and pray that "low-fat, eat healthy whole grains" goes the way of Detroit gas guzzlers and sub-prime mortgages.

Drug industry "Deep Throat"

A Heart Scan Blog reader brought the following letter from a former pharmaceutical sales representative to congress to my attention.

Interesting excerpts:

As a former drug representative for Eli Lilly, I spent 20 months increasing the market share of my company’s drugs. I was recruited fresh from college with an eager desire to employ my degree in molecular biology and biochemistry. Shortly after my hiring, it became clearly apparent that a drug sale had much more to do with establishing personal relationships than it did with understanding the latest science. However, any doubts I held regarding the effectiveness of such methods were dispelled by the results of my persuasiveness and the financial rewards I received for my efforts. The latter also helped me rationalize the many ethically dubious situations I routinely encountered in my work. Upon my departure from the industry, I began working for the public’s health. Seven years later, as a result of my experiences and education I am more convinced than ever that the goals of the pharmaceutical industry often stand in direct conflict with the practice of ethical and responsible medicine. Nothing in my recent research causes me to believe that my experiences were anything but typical of the training and practice of the majority of drug reps plying their trade today.


“There’s a big bucket of money sitting in every [doctor’s] office.” – Michael Zubillaga, Astra Zeneca Regional Sales Director, Oncology


The majority of drug reps entering the work force today are young and attractive. The ranks of reps are replete with sexual icons: former cheerleaders, ex-military, models, athletes. Of course, as a sales job, the reps must be eloquent and convincing. Depending on the population, certain ethnicities are preferred either to make the rep distinct among other reps or to provide them with a cultural advantage in connecting with their clients. Noticeably lacking among most new reps is any significant scientific understanding. My personal case illustrates this point rather vividly: In my training class for Eli Lilly's elite neuroscience division, selling two products that constituted over 50% of the company's profits at the time, none of my 21 classmates nor our two trainers had any college level scientific education. In fact, that first day of training, I taught my class and my instructors the very basic but crucial process by which two nerve cells communicate with one another. It is very likely that the majority of my class couldn't explain the difference between a neuron and a neutron prior to sales school. While it's certainly a bonus to have a scientifically educated representative, it is far from a primary recruitment criterion. Youth is a much higher criterion for the sales position.

Sales representative trainers are almost always veteran sales representatives and consequently, much of the training they offer is implicit in the anecdotes they give. This informal training parallels the standard training offered by the industry and in many ways compliments it. It is tacitly accepted by management and perceived as the "real" training by many veteran sale representatives. Among the more dubious "unofficial" lessons a new rep learns are: how to manipulate an expense report to exceed the spending limit for important clients, how to use free samples to leverage sales, how to use friendship to foster an implied "quid pro quo" relationship, the importance of sexual tension, and how to maneuver yourself to becoming a necessity to an office or clinic.

The most troubling aspect of pharmaceutical sales is systematic befriending of our clients. In addition to the psychological profiling mentioned above, drug reps are taught to constantly be on the lookout for personal effects that will help us connect to our doctors. When entering an office for the first time, we nonchalantly survey it for clues to ingratiate ourselves with our client. Similarly, conversations are intentionally steered into the realm of personal details such as religion, family, or hobbies to acquire similar information. As a matter of training, we collect this data subtly. In the course of a conversation with clients, we may glean facts about their prescribing preferences, the dates of their children’s birthdays, where they were born, or what music they enjoy. Training encourages us to commit these details to memory just long enough to return to our cars and instantly type up a “call report” listing the details of our conversation. On a daily basis, we connect our computers to a central database that uploads the information we’ve acquired, allowing us to share it with our partner drug reps and company marketers. Subsequently, drug reps interweave pieces of conversation specifically tailored to appeal to their client drawn from personal information that wasn’t necessarily shared with them. For example, Dr. Jones will be nothing but grateful when I supply him with a cake celebrating his children’s birthday when, in fact, he told my partner (and not me) the birthdates several months prior in a personal conversation.


The writer's comments ring true: The relentless attention-grab of sales representatives, using clever tactics that include access to detailed records of physician prescribing habits, big smiles and eye-winking, are detailed perfectly.

There's nothing wrong with a business doing its job by marketing its products and services. What is so wrong about this picture is that one side is so well-equipped, heavily funded, with access to extraordinary resources that the other side (physicians) don't have. And the physicians aren't the victims--YOU are.

A middle-aged, receding hairline physician, faced with a 28-year old attractive woman asking all manner of ingratiating questions but knowing full well what she is doing, having strategized for weeks on how to manipulate the behavior of her "mark," is helpless.

Like the mortgage-backed security crisis, we've reached another phenomenon of crisis proportions. Direct-to-consumer drug advertising, drugs for non-conditions and well people, pinpoint marketing of drugs to physicians--it's all gone too far.

Personally, drug representatives are not welcome in my office. This generally prompts puzzled, followed by angry, looks from the representatives, often traveling with a district supervisor hoping to help polish their pitch. If patients didn't request free samples, the reps would not step foot in the office.

Triglyceride Buster-Update

In the last Heart Scan Blog post, I described Daniel's experience reducing his triglycerides from 3100 mg/dl to around 1100 mg/dl with use of omega-3 fatty acids from fish oil, along with modifications in his diet. This was accomplished in the space of around two weeks.

An update: Daniel has continued another 10 days on his fish oil, along with elimination of wheat, cornstarch, and sugars.

Repeat triglyceride: 202 mg/dl. That's 93.5% reduction in the space of three weeks--no drugs involved.

Daniel really did nothing extraordinary. He simply followed the simple advice I provided to take a moderate dose of EPA+DHA from over-the-counter fish oil supplements, along with elimination of the foods that are extravagant triggers of triglycerides.

He's got just a little further to go to achieve the biologically ideal level of less than 60 mg/dl. You can see that it is not really that difficult--provided someone didn't load you down with nonsense about "cutting your fat," or statin or fibrate drugs.

Triglyceride buster

Two weeks ago, Daniel started with a triglyceride level of 3100 mg/dl, a dangerous level that had potential to damage his pancreas. The inflammatory injury incurred could leave him with type I diabetes and inability to digest foods, since the insulin-producing capacity and the enzyme producing capacity of the pancreas are lost.

Daniel added 3600 mg of omega-3s per day. Within 10 days, his triglycerides dropped nearly 2000 mg to just over 1100 mg/dl--still too high, but an incredible start.

The power of omega-3 fatty acids from fish oil to reduce triglycerides is illustrated most graphically by people with a condition called "familial hypertriglyceridemia" that is responsible for triglyceride levels of 500, 1000, even several thousand milligrams. That's what Daniel has. Given appropriate doses of omega-3s, triglycerides drop hundreds, even thousands, of milligrams.

No question: Omega-3 fatty acids from fish oil are the best tool available for reduction of triglycerides. The effect is dose-dependent, i.e., the more you take, the greater the triglyceride reduction.

How omega-3s exerts this effect is unclear, though there is evidence to suggest that omega-3s suppress several nuclear receptors involved in triglyceride (VLDL) production and increase the expression or activity of the enzyme lipoprotein lipase, an enzyme that clears triglycerides from the blood.

I am continually surprised at the number of people with high triglycerides who are still treated with a fibrate drug, like Tricor, or a statin drug, when fish oil--widely available, essentially free of side-effects, with a proven cardiovascular risk-reducing track record--should clearly be the first choice by a long stretch.

Among its many benefits, omega-3 fatty acids from fish oil also:

Reduce matrix metalloproteinases (MMP)--Two fractions of MMPs, MMP-2 and MMP-9, are inflammatory enzymes present in atherosclerotic plaque that are suspected to trigger plaque "rupture." Omega-3s have been shown to reduce both forms of MMP.

Block uptake of lipids in the artery wall--Suggested by a study in mice.

Modify postprandial responses--In the first few hours after eating (the "postprandial" period), a flood of digestive byproducts of a meal are present in the bloodstream. While research exploring postprandial effects is still in its infancy, it is clear that omega-3 fatty acids have the capacity to favorably modify postprandial patterns. One common surrogate measure for postprandial abnormalities is intermediate-density lipoprotein, or IDL, that we obtain in fasting blood through lipoprotein panels like NMR and VAP. With sufficient omega-3s alone, IDL is completely eliminated.

Unfortunately, most of my colleagues, if they even think to use omega-3s, choose to use the prescription form, Lovaza. Indeed, several representatives from AstraZeneca, the pharmaceutical outfit now distributing this miserably overpriced product, frequently barge their way into my office poking fun at our use of nutritional supplements instead of the prescription Lovaza. "But insurance covers it in most cases!" they plead. "And your patients will know that they're getting the real product, not some fake. And they'll have to take fewer capsules!"

I never use Lovaza to reduce triglycerides, even in familial hypertriglyceridemia--the FDA-approved indication for Lovaza--and have not yet seen any failures, only successes.

Newsweek, Time, and other fronts for the drug industry

I used to believe that conventional print media--newspapers, magazines--were unbiased, untouchable flames of truth. Perhaps there was a time when this was true, when the young reporter, eager to change the world, uncovered the story that righted some huge wrong.

Those days are drawing to a close.

Today, the once powerful print media are collapsing due to the competition of the cheaper, broader reach of the internet.

Jogging does NOT cause heart disease


Periodically, I'll come across a knuckleheaded report like this one from Minneapolis:

Marathon Man’s Heart Damaged by Running?


Of course, the obligatory story about how a cardiologist came to the rescue and "saved his life" with a stent follows. In other words, a stent purportedly saved the life of this vigorous man with no symptoms and high capacity for exercise.

Does vigorous exercise, whether it's marathon running, long-distance biking, or triathlons, cause coronary disease? Should all vigorous athletes run to their doctor to see if they, too, need their lives to be "saved."

Let me tell you what's really going on here. People with the genetic pattern lipoprotein(a), or Lp(a), tend to be slender, intelligent and athletic. For genetic reasons, these people gravitate towards endurance sports like long-distance running. Lp(a) is a high-risk factor for coronary disease. It is the abnormality present in the majority of slender, healthy people who are shocked when they receive a high heart scan score or have a heart attack or receive a stent. (I call Lp(a) "the most aggressive known coronary risk factor that nobody's heard about.")

The association between endurance exercise and heart disease is just that: an association. It does not mean that exercise is causal. Having seen coronary plaque detected with heart scans in many runners, virtually all of whom demonstrated increased Lp(a), I believe that Lp(a) is causal.

Unfortunately, the man in the Minneapolis story, now that his life is "saved," will likely be advised to take a statin drug and follow a low-fat diet . . . you know, the diet that increases Lp(a).

Warning: Your pharmacist may be hazardous to your health

Pharmacists can be very helpful resources when it comes to questions about prescription drugs.

The operant word here is drugs.

What they are most definitely not expert on are nutritional supplements. In fact, a day doesn't pass by without having to dispell one falsehood or another conveyed to a patient about a nutritional supplement by a pharmacist.

Among the more common falsehoods told to patients by pharmacists:

"You have to take Niaspan. Sloniacin doesn't work."

Patent nonsense. A few years back, I was the largest prescriber of Niaspan in Wisconsin. Although I am embarassed to admit it, I also spoke for the company, educating fellow physicians on the value of niacin for correction of lipid disorders.

Then I shifted to Sloniacin due to cost--it costs 1/20th the cost of prescription Niaspan. I examined the pharmacokinetic data (pattern of release in the body), the published literature (e.g., the famous HATS Trial), and have used Sloniacin over 1000 times in patients. In my experience, there is no difference: no difference in efficacy, no difference in safety, no difference in side-effects. There is a BIG difference in price.

Unfortunately, most pharmacists get their information on niacin from the Niaspan representative.


"You shouldn't be taking vitamin D supplements. I have prescription vitamin D here."

What the pharmacist means is that you should replace your vitamin D3, or cholecalciferol--the form recognized as vitamin D by the human body--with the plant form of vitamin D, vitamin D2 or ergocalciferol.

Since when is a plant form of a hormone (vitamin D is a potent hormone, not a vitamin; it was misnamed) better than the human form?

I've previously talked about this issue in a blog post called Vitamin D for the pharmaceutically challenged.

The notion that D2 is somehow superior to the real thing, D3, is absurd. I use D3 only in my practice and have checked blood levels thousands of times. As long as the D3 comes as a gelcap, drops, or powder in a capsule, it works great, yielding predictable and substantial increases in blood levels of 25-hydroxy vitamin D. If it comes as prescription D2 (or over-the-counter D2), I have seen many failures: no increase in blood levels of vitamin D or meager increases.

Prescription status is no guarantee of effectiveness.


"Why do you need iodine? You already get enough from food."

The NHANES data over the last 25 years argue otherwise: Iodine deficiency is growing, particularly as people are avoiding iodized salt and the iodine content of processed foods is diminishing. The explosion in goiters in my office also suggest this is no longer a settled issue.

On the positive side, it is exceptionally easy to remedy with an inexpensive iodine supplement. That is, until the pharmacist intervenes and injects his bit of nutritional mis-information.


I'm not bashing pharmacists. In fact, Track Your Plaque's own Dr. BG has a pharmacy background, and she is an absolute genius with nutritonal supplements. But she is a rare exception to the rule: Most pharmacists know virtually nothing about nutritional supplements. You might as well ask your hairdresser.

"Healthy" people are the most iodine deficient

Ironically, the healthiest people are the most likely to be deficient in iodine.

Why?

Healthy people tend to:

--Avoid iodized salt because of public health advice to limit sodium
--Use sea salt to obtain minerals like magnesium--but sea salt contains little iodine
--Limit meat--Carnivores obtain more iodine than vegetarians or vegans. In one study, up to 80% of vegans were iodine-deficient (Krajcovicova-Kudlackova M et al 2003).
--Exercise--Substantial amounts of iodine are lost through sweating. In a study of high school soccer players, 38.5% were severely iodine deficient, compared to 2% of sedentary students (Mao IF et al 2001).


That is indeed what I am seeing in my office, as well: The healthiest, most attentive to healthy eating, and most physically active are the ones showing up with small goiters (enlarged thyroid glands) and increased TSH and low free T4 levels.

Why am I checking thyroid and talking about iodine? Because even the smallest degree of thyroid dysfunction can double, triple, or quadruple your risk for cardiovascular events. See the posts Is normal TSH too high? and Thyroid perspective update.

What kind of iodine do you take?

The results of the latest Heart Scan Blog poll are in.

204 respondents answered the question:


Do you take an iodine supplement?

The responses:

Yes, I take Iodoral, Lugol's, or SSKI
26 (12%)

Yes, I take potassium or sodium iodide
19 (9%)

Yes, I take kelp tablets or powder
64 (31%)

No, I rely on generous use of iodized salt
23 (11%)

No, I don't supplement iodine at all
66 (32%)

Isn't iodine something you put on cuts and scratches?
6 (2%)


I am heartened by the number of respondents taking iodine in some form. After all, iodine is an essential trace mineral. Without it and health suffers, often dramatically.

However, I am concerned by the percentage of people who don't supplement iodine at all: 32%. Interestingly, this is approximately the proportion of people who come to my office who also do not supplement iodine who are now showing goiters, or enlarged thyroid glands due to iodine deficiency. Goiters lead to hypothyroidism (low thyroid hormone levels), followed by hyperactive nodules, not to mention undesirable effects like weight gain, fatigue, hair loss, constipation, intolerance to cold, higher LDL cholesterol and triglycerides, and heart disease.

11% of respondents report using lots of iodized salt. This may or may not be sufficient to provide enough iodine to prevent goiter and allow normal thyroid function. The success of this strategy depends to a great extent on how often salt is purchased. Salt that sits on the shelf for more than a month is devoid of iodine, given iodine's volatility.

I am also favorably impressed by the number of people who take "serious" iodine supplements like Lugol's solution, Iodoral, or SSKI. Of course, people who read The Heart Scan Blog tend to be an unusually informed, healthy population. The 12% of people in the poll who take these forms of iodine does clearly not mean that 12% of the general population also takes them. But 12% is more than I would have predicted.

On the Track Your Plaque website, we are awaiting an interview with iodine expert, Dr. Lyn Patrick. I'm hoping for some juicy insights.

Identical twins and the explosive influence of weight

A Track Your Plaque member, Eugene, brought this fascinating story to my attention.

Eugene has two nephews, identical twins aged 35 years. Despite their similar personalities and appearances, somehow these two drifted apart in weight with Steve outweighing Alfred by 30 lbs.

Eugene explains:

These guy's are big not, but overly fat. Just big. One is about 30 lbs heaver than the other. They live 2 blocks apart, they ate the same (together) meal the night before the blood work. Their mother is a type 2 diabetic with a heart condition. Steve does not eat as well as his twin, junk food and a lot of processed starches.


Their results:



LDL-Particle number
Alfred 900
Steve 2256

Small LDL-P
Alfred 400
Steve 1639

HDL-C
Alfred 44
Steve 36

Triglycerides
Alfred 85
Steve 355

Metabolic Syn.
Alfred no
Steve yes


Glucose

Fasting
Alfred 93
Steve 112

1hour
Alfred 134
Steve 206

2 hour
Alfred 105
Steve 172


Identical twins begin with the very same genetic background. As these two graphically illustrate, weight can have a profound influence in the genetically susceptible.

LDL particle number alone is 250% greater in the heavier twin. The dreaded small LDL particle is over 400% worse! Look also at the dramatic differences in blood sugar.

If you ever had any doubts about the importance of excess weight and nutrition, just remind yourself of this fascinating illustration.

Thanks, Eugene.

Low-fat diets raise triglycerides

Martin, a hospital employee, knowing that I fuss a great deal with lipids and lipoproteins, showed me his lipid panel because the result triggered a "panic value" for triglycerides at 267 mg/dl. He asked if he should go on a serious low-fat diet.

I asked Martin what he had for breakfast: a whole wheat bagel with no-added-sugar jam. Lunch: a turkey sub on whole grain bread, no mayonnaise. Snacks: baked chips, pretzels ("a low-fat snack!").

In years past, if person developed high triglycerides levels, a very low-fat diet was prescribed. Someone would come to the hospital, for instance, with abdominal pain from pancreatitis (an inflamed pancreas)due to the damaging effects of triglyceride levels >1000 mg/dl. For this reason, many people still believe that all instances of elevated triglycerides should be treated with a reduction in fat intake.

This is absolutely wrong. While a fat restriction may reduce triglycerides in genetically-programmed responses when triglycerides are >1000 mg/dl, lesser levels of high triglycerides of, say 250 or 300 mg/dl, do not respond to dietary fat restrictions as a sole strategy.

Yes, a reduction in unhealthy fats (saturated, trans, polyunsaturated) helps. But a reduction in fats of all sorts is not necessary and can, in fact, worsen the problem. We learned this lesson years ago with the Ornish diet and similar ultra low-fat approaches. When you reduce fat intake significantly to <10% of calories, triglycerides go way up. In those days, it wasn't uncommon to see triglycerides skyrocket past 200 or 300 mg/dl on these diets.

Why are triglycerides important? Triglycerides are an ingredient in creating the lipoproteins VLDL, IDL, small LDL. Elevated triglycerides trigger a drop in HDL, a shift towards small, ineffective HDL, and contribute to heightened inflammation. Higher triglycerides also tend to go hand in hand with lipoproteins that persist for extended periods (12-24 hours or longer) in the blood after a meal.

Triglycerides respond very nicely to a dramatic reduction in processed carbohydrates, especially wheat and corn. Of course, wheat is the bulk of the problem, since it has grown to occupy an enormous role in many people's diet, not uncommonly eaten 3,4, or 5 times per day in various forms, as it has in Martin's diet. Eliminating all sources of high-fructose corn syrup is also helpful, since high-fructose corn syrup shoots triglycerides way up. (Recall that high-fructose corn syrup is everywhere: ketchup, beer, low-fat or non-fat salad dressings, breads, fruit drinks, sports drinks, breakfast cereals, etc.)

Curiously, it is a fat that also powerfully reduces triglycerides in the form of fish oil. In the Track Your Plaque program, fish oil, taken at truly effective doses of 4000 mg per day or more (to provide at least 1200 mg EPA+DHA), is our number one choice after reduction of processed carbohydrates for reduction of high triglycerides.

The dreaded niacin "flush"

As most anybody who takes niacin knows, it can cause a hot flushed feeling over the chest and face that is generally harmless, though quite annoying.

Many doctors are frightened by this response and will warn patients off from niacin. Some people who take niacin are so annoyed that they find it intolerable.

However, a very simple maneuver can relieve the hot flush in over 90% of instances: Drink water. Let me explain.

I usually instruct patients to take niacin at dinnertime. That way, food slows absorption modestly. I also ask them to drink water with dinner. If the flush occurs after dinner (usually 30-60 minutes later), then drinking two 8-12 oz glasses of water immediately breaks the flush within 3 minutes in the great majority of people. It's quite dramatic.

Doing this around dinner (lunch works just as well) allows sufficient time to clear the excess water from your body before bedtime and spare you the aggravation of disrupted sleep to urinate. Drinking plenty of water works most of the time. Only an occasional person will need to take a 325 mg uncoated aspirin to more fully break the flush. I generally suggest that patients keep the uncoated aspirin in reserve if the water doesn't provide relief within a few minutes.

Thankfully, the intensity of the niacin flush lessens, often disappears, with chronic use.

Why do some people develop the flush and other don't? It is believed that some people metabolize niacin more rapidly to a compound called nicotinuric acid, a niacin metabolite that causes dilation (relaxation) of skin capillaries--thus the flush. The rapidity of converting niacin to nicotinuric acid is determined genetically.

An occasional person really struggles with niacin to the point of intolerance. However, on the positive side, these people may also be "hyper-responders" to niacin, i.e., they show exagerated benefits in raising HDL, reducing small LDL, etc., from small doses such as 250 mg per day.

If you experience the hot flush of niacin, think water to put out the fire.

A cure for pessimism?

Followers of the Track Your Plaque program know that we place great value on having an optimistic outlook. Not only are you more likely to be happy and successful in life, you are also far more likely to drop your CT heart scan score. Virtually everyone who has succeeded in dropping their heart scan score dramatically has been an optimist, including our most recent record holder who dropped his score an astounding 51%.

But what if you are a pessimist, someone who gripes and complains about everything, sees the bad in other people, blames others for anything and everything that goes wrong--yet you still desire to drop your heart scan score? Are you a lost cause? Should you just give up?

I don't think so. I will admit that, of all the hurdles we encounter in trying to purposefully stop or reduce heart scan scores, overcoming a pessimistic attitude is probably the toughest. Tougher than being overweight, maybe tougher than even Lp(a).

Perhaps there's a solution in two years of psychotherapy sessions with a counselor, or exploring unresolved childhood conflicts with a psychologist, or an antidepressant drug. Pessimism is, after all, a deeply-ingrained pattern of behavior, something that can't be changed just by suggesting it or simple self-realization.

The closest thing I know of to a quick and relatively easy solution for converting a pessimist to an optimist is very simple:

Do good things for other people.

Something peculiar happens to the pessimist when he/she starts to help others. They are less threatened by other people (since much griping is really fear in disguise), begin to see others as vulnerable creatures who could use their help rather than sources of annoyance, and a kinship with others is acquired.

Doing good things can mean giving blood, donating money to the Sierra Club or other charity, volunteering with the Boy Scouts, tipping the hard working waitress trying to pay for college more generously, paying compliments to people around you, helping a neighbor carry the groceries when you see him struggling, showing a child how to make a paper airplane . . .

Good deeds can take a million different forms. But it must involve you personally. It can't mean delegating a helpful activity to your spouse. You must also do it frequently, not just once a year. It doesn't have to cost money, it doesn't have to involve a lot of time (though your personal bodily involvement does yield the greatest return in optimism). These are things anyone can do and help make the world around you a little better.

If taking these small steps towards an optimistic attitude are too much for you, then I would worry that you are destined to fail in dropping your heart scan score.

(Lack of ) Quality of nutritional supplements

In my last post, I blogged about how we must not confuse marketing with truth. They are often two different things.

A patient I saw today was absolutely convinced that his fish oil was the best available in the world: purer, uncontaminated by mercury or pesticides--"not like that other crap on the shelves." I asked him how he knew this. "They say so," he proudly declared.

Do you recognize this? He fell for the marketing. While there may be some truth in the manufacturer's claims, you can't believe it from the mouth of the manufacturer. True judgements about quality and purity have to come from an independent source like Consumer Reports, Consumer Lab, or the FDA.

But the FDA doesn't regulate the quality and purity of nutritional supplements. On the positive side, this has allowed supplement manufacturers to keep costs down, not having to navigate arcane and complex regulatory restrictions.

On the negative side, a fair number of supplement manufacturers get away with 1) producing supplements that fail to contain the stated amounts of ingredients, occasionally containing none of the essential ingredient(s), 2) contain contaminants like lead, and 3) make extravagant and often unfounded claims like "superior", "more effective", and "purer". (DHEA, for instance, is a particular landmine of poor quality. I recently suggested that a patient take DHEA; despite consistently taking 50 mg of a specific brand for several months, the blood level of DHEA-S didn't budge one bit--there was likely little or none in the capsule.)

The Fanatic Cook at http://fanaticcook.blogspot.com has posted some very insightful discussions on this issue and the proposed FDA regulations of supplements. They're worth perusing.

I really wish regulation weren't necessary and that the industry could have policed itself. But it clearly has failed and perhaps federal oversight is not such a bad thing, as long as the FDA regulations restrict themselves to oversight over quality and purity and not to efficacy. It's the efficacy regulation that could hogtie innovation in supplement development.

Marketing and truth are not the same

I often remind people: Don't confuse marketing with the truth.

Today, I spent a total of probably an hour and a half dissuading patients that some crazed piece of marketing trying to sell them something was not the same as truth.

I spent approximately 40 minutes alone with a woman who was absolutely convinced that:

--Nattokinase would cure her of all heart disease. It does not. Despite the promising health benefits of natto and vitamin K2 supplementation, nattokinase is a scam with no basis in science nor logic.

--Niacin destroys your liver and homeopathic remedies are superior. Quite simply, homeopathy = quackery. No rational thinking scientist endorses the utter nonsense practiced in this strange and outrageous set of practices that requires you to suspend all reason.

--Sufficient vitamin D is obtainable through a "potent" multivitamin. I know of no multivitamin preparation that even begins to provide the dose of vitamin D that is actually required by adults, nor is it absorbed since these D preparations are powder based.

--Fish oil will poison you with mercury. Accordingly, one brand of fish oil claims to be the only safe form. Those of you following these posts, or the reports of the USDA and FDA, as well as the reports of Consumer Reports and Consumer Lab (www.consumerlab.com) know that, unlike fish itself, there is no mercury in fish oil capsules.

--All coronary atherosclerotic heart disease is caused by heavy metal poisoning. Thus chelation with EDTA represents a cure for heart disease.


People are inundated with marketing that promise extravagant cures, remove need for any medication, make you smarter, sexier, thinner, and on and on.

If you see a TV ad for Ford that says they make the best cars in the U.S., do you immediately run out and put a For Sale sign on your GM car and buy a Ford? No, of course not. You recognize the ad for what it is: marketing. It may be true, but a TV commercial is not enough to convince you.

Then why would an ad promising extraordinary cures for cancer or heart disease convince you that this is true? It should not. Marketing ads should only serve to alert you to the possibility of value or benefit, but should never-- never--stand alone as proof. Take marketing for what it is: marketing of a product or service, not a scientific report, not a factual report, not news.

Marketing is advertising. Period.

More on erectile dysfunction

Several facts on erectile dysfunction and coronary plaque:


If you have erectile dysfunction, there's at least a 50% chance you also have coronary plaque.

If you have coronary plaque by a CT heart scan, there's a 50% chance you have erectile dysfunction.

If you have symptomatic coronary disease (chest pains, breathlessness, prior heart attack), there's a 90% chance you also have erectile dysfunction.


Coronary disease is characterized by a dysfunctional state of the "endothelium", or inner lining of the coronary arteries. Erectile dysfunction is characterized by dysfunction of the endothelium of the penile circulation. Same phenomenon, different territories. (There are other differences, of course, but the two conditions share this fundamental phenomenon.)


If you have any doubts about the physiologic effects of the supplement, l-arginine, just give it a try if you have erectile dysfunction. The erection enhancing effects alone should convince you that a genuine artery-dilating effect is exerted by this very powerful nutritional supplement.

If l-arginine fails by itself to restore full erectile capacity, there are additional strategies, both nutritional and medical, that you can consider.

Our newest Track Your Plaque Special Report on erectile dysfunction is coming out any day now.

High LDL cholesterol--only

As a sequel to my last post, just how often can we blame an isolated high LDL cholesterol as the cause of coronary plaque and a heart scan score?

In other words, how often does someone prove to have only LDL cholesterol as the cause of a heart scan score . . . and nothing else? No low HDL, small LDL, lipoprotein(a), a post-prandial (after-eating) intermediate-density lipoprotein, inflammatory responses, phospholipase A2, high triglycerides, vitamin D deficiency, etc.

Rarely. In fact, I can truly count the number of people who have only LDL cholesterol as their sole cause of coronary atherosclerotic plaque on one hand. It is really an infrequent situation.

Far more commonly, people have 5, 6, 7 or more reasons for coronary plaque.

Thus, the idea that a statin drug to reduce LDL will cure heart disease is completely folly. It does happen--but rarely. I think I've seen it happen twice. Much more commonly, a program that addresses all the causes of coronary plaque yields far superior benefits.

In my view, an effort to identify all the causes is relatively easy, makes far better sense, and provides you much greater assurance that you will succeed in conquering heart disease and removing its evil influence from your life.

Heart disease = statin deficiency

Judging from the conversations I hear from colleagues, what I hear from the media, and drug company advertising, you'd think that heart disease has one cause--a deficiency of statin drugs.

As their thinking goes, if you have coronary disease, you need a statin drug (Lipitor, Zocor, Crestor, pravachol, etc.). If you have progressive coronary disease, you need more statin drug. If you have a heart attack while on a statin drug, you need even more statin drug.

Some "experts" have even proposed that we do away with LDL cholesterol and we just give everybody a statin drug at high doses.

Does this make any sense to you?

Doesn't it make better sense that if someone has progressive heart disease or heart attack while on a statin drug, then target the other causes largely unaffected by a statin drug? Perhaps if LDL cholesterol remains high on the statin drug, then a higher dose is justified. But more often than not, it's not a high LDL on statin drugs that responsible, it's other causes. And there's many of them: low HDL, VLDL, IDL, Lp(a), deficiency of omega-3 fatty acids, inflammatory processes, vitamin D deficiency, among others. (An important exception to this is when the conventional calculated LDL substantially underestimates true LDL as measured by LDL particle number by NMR, apoprotein B, or 'direct' LDL.)

Imagine someone has pneumonia. After 2 weeks of antibiotics, they are only partly better. The solution: a higher dose of the same antibiotic--but never question if it was the right antibiotic in the first place. That's what is going on in heart disease.

The doctors have been brainwashed into believing this $22 billion dollar per year bit of propaganda. The drug companies actively try to recruit the public into believing the same. Don't fall for it.

The statin drugs do indeed have a role. But they are not the complete answer. More of the same when disease progresses makes no sense at all.

Fish oil and mercury

I often get questions about the mercury content in fish oil. I've even had patients come to the office saying their primary care doctor told them to stop fish oil to avoid mercury poisoning.

Manufacturers of fish oil also make claims that this product or that ("super-concentrated", "pharmaceutical grade", "purified", etc.) is purer or less contaminated than competitors' products. The manufacturers of the "drug" Omacor, or prescription fish oil, have added to the confusion by suggesting that their product is the most pure of all, since it is the most concentrated of any fish oil preparation (900 mg EPA+DHA per capsule). They claim that "OMACOR is naturally derived through a unique, patented process that creates a highly concentrated, highly purified prescription medicine. By prescribing OMACOR® (omega-3-acid ethyl esters), a prescription omega-3, your doctor is giving you a concentrated and reliable omega-3. Each OMACOR capsule contains 90% omega-3 acids (84% EPA/DHA*). Nonprescription omega-3 dietary supplements typically contain only 13%-63% EPA/DHA."

How much truth is there in these concerns?

Let's go to the data published by the USDA, FDA, and several independent studies. Let's add to that the independent (and therefore presumably unbiased) analyses provided by Consumer Reports and Consumer Labs (www.consumerlab.com). How much mercury has been found in fish oil supplements?

None.

This is different from the mercury content of whole fish that you eat. Predatory fish that are at the top of the food chain and consume other fish and thereby concentrate organic methyl mercury, the toxic form of mercury. Thus, shark, swordfish, and King mackerel are higher in mercury than sardines, herring, and salmon.

The mercury content of fish oil capsules have little to do with the method of processing and much more with the animal source of oil. Fish oil is generally obtained from sardines, salmon, and cod, all low in mercury. Fish oil capsules are not prepared from swordfish or shark.

Thus, concerns about mercury from fish oil--regardless of brand--are generally unfounded, according to the best information we have. Eating whole fish--now that's another story for another time. But you and I can take our fish oil to reduce triglycerides, VLDL, IDL, small LDL, and heart attack risk without worrying about mercury.

Heart Scan Blog Redux: Cheers to flavonoids

Because in Track Your Plaque we've been thinking a lot about anthocyanins, here's a rerun of a previous Heart Scan Blog post about red wine. (Anthocyanins are among the interesting flavonoids in red wine, along with resveratrol and quercetin.)


The case in favor of healthful flavonoids seems to grow bit by bit.

Flavonoids such as procyanadins in wine and chocolate, catechins in tea, and those in walnuts, pomegranates, and pycnogenol (pine bark extract) are suspected to block oxidation of LDL (preventing its entry into plaque), normalize abnormal endothelial constriction, and yield platelet-blocking effects (preventing blood clots).

Dr. Roger Corder is a prolific author of many scientific papers detailing his research into the flavonoids of foods, but wine in particular. He summarizes his findings in a recent book, The Red Wine Diet. Contrary to the obvious vying-for-prime-time title, Dr. Corder's compilation is probably the best mainstream discussion of flavonoids in foods and wines that I've come across. Although it would have been more entertaining if peppered with more wit and humans interest, given the topic, its straightfoward, semi-academic telling of the story makes his points effectively.

Among the important observations Corder makes is that regions of the world with the greatest longevity also correspond to regions with the highest procyanidin flavonoids in their wines.




Regarding the variable flavonoid content of wines, he states:

Although differences in the amount of procyanidins in red wine clearly occur because of the grape variety and the vineyard environment, the winemaker holds the key to what ends up in the bottle. The most important aspect of the winemaking process for ensuring high procyanidins in red wines is the contact time between the liquid and the grape seeds during fermentation when the alcohol concentration reaches about 6 percent. Depending on the fermentation temperature, it may be two to three days or more before this extraction process starts. Grape skins float and seeds sink, so the number of times they are pushed down and stirred into the fermenting wine also increases extraction of procyanidins. Even so, extraction is a slow process and, after fermentation is complete, many red wines are left to macerate with their seeds and skins for days or even weeks in order to extract all the color, flavor, and tannins. Wines that have a contact time of less than seven days will have a relatively low level of procyanidins. Wines with a contact time of ten to fourteen days have decent levels, and those with contact times of three weeks or more have the highest.

He points out that deeply-colored reds are more likely to be richer in procyanidins; mass-produced wines that are usually "house-grade" served at bars and restaurants tend to be low. Some are close to zero.

Wines rich in procyanidins provide several-fold more, such that a single glass can provide the same purported health benefit as several glasses of a procyanidin-poor wine.

So how do various wines stack up in procyanidin content? Here's an abbreviated list from his book:

Australian--tend to be low, except for Australian Cabernet Sauvignon which is moderate.

Chile--only Cabernet Sauvignon stands out, then only moderate in content.

France--Where to start? The French, of course, are the perennial masters of wine, and prolonged contact with skins and seeds is usually taken for granted in many varieties of wine. Each wine region (French wines are generally designated by region, not by variety of grape) can also vary widely in flavonoid content. Nonetheless, Bordeaux rate moderately; Burgundy low to moderate (except the village of Pommard); Languedoc-Roussillon moderate to high (and many great bargains in my experience, since these producers live in the shadow of its northern Bordeaux neighbors); Rhone (Cote du Rhone) moderate to high, though beware of their powerful "barnyard" character upon opening; decanting is wise.

Italy--Much red Italian wine is made from the Sangiovese grape and called variously Chianti, Valpolicella, and "super-Tuscan" when blended with other varietals. Corder rates the southern Italian wines from Sicily, Sardinia, and the mainland as high in procyanidins; most northern varieties are moderate.

Spain--Moderate in general.

United States--Though his comments are disappointingly scanty on the U.S., he points out that Cabernet Sauvignon is the standout for procyanidin content. He mentions only the Napa/Sonoma regions, unfortunately. (I'd like to know how the San Diego-Temecula and Virginian wines fare, for instance.)

The winner in procyanidin content is a variety grown in the Gers region of southwest France, a region with superior longevity of its residents. The wines here are made with the tannat grape within the Madiran appellation; wines labeled "Madiran" must contain 40% or more tannat to be so labeled (such is a quirk of French wine regulation). Among the producers Dr. Corder lists are Chateau de Sabazan, Chateau Saint-Go, Chateau du Bascou, Domaine Labranche Laffont, and Chateau d'Aydie. (A more complete list can be found in his book.)

How does this all figure into the Track Your Plaque program? Can you succeed without red wine? Of course you can. I doubt you could do it, however, without some attention to flavonoid-rich food sources, whether they come from spinach, tea, chocolate, beets, pomegranates, or red wine.

Though my wife and I love wine, I confess that I've never personally drank or even seen a French Madiran wine. Any wine afficionados with some advice?

Can wheat elimination cure ulcerative colitis?

Tammy is a 36-year old mother of three young children. Since age 20, she has suffered with the debilitating symptoms of ulcerative colitis: constant, gnawing abdominal pain; frequent diarrhea, often bloody.



Tammy has had to take several medications, some with significant side-effects, all of which provided only partial relief from the pain and diarrhea. Her gastroenterologist and surgeon were planning a colectomy (removal of the colon) with creation of an ileostomy (rerouting of the small intestine to the abdominal surface, which would require Tammy to wear an ileostomy bag under her clothes for the rest of her life).



Although Tammy had previously tested negative for celiac disease (an allergic sensitivity to the gluten in wheat products), I urged her to attempt a trial of a wheat-free diet. Having witnessed many people experience relief from irritable bowel syndrome, acid reflux, and other common gastrointestinal complaints, all while trying to reduce blood sugar and small LDL, I'd hoped that Tammy would obtain at least some small improvement in her terrible symptoms.



I therefore urged Tammy to try it. After all, what was there to lose? Tammy grudgingly agreed.



She returned 6 months later. Her report: She had lost 38 lbs, virtually all of it within the first 6-8 weeks. Her diarrhea and cramping were not better, but gone. She was down to a single medicine from her former list of drugs.



I am unsure what proportion of people with ulcerative colitis or other inflammatory bowel diseases like Crohn's will experience a result like Tammy's. Perhaps it's only a minority. But I take this another piece of evidence that this enormously destructive thing called wheat has no place in the human diet.



We have no facts or figures on the prevalence of various forms of wheat intolerance in the U.S. When I contacted the Celiac Disease Foundation, they had no figures on the number of fatalities per year in the U.S. from celiac disease. But if there are 2-3 million Americans with celiac disease, there are probably 100 times that many people with various forms of wheat intolerance.



Postprandial pile-up with fructose

Heart disease is likely caused in the after-eating, postprandial period. That's why the practice of grazing, eating many small meals throughout the day, can potentially increase heart disease risk. Eating often can lead to the phenomenon I call triglyceride and chylomicron "stacking," or the piling up of postprandial breakdown products in the blood stream.

Different fatty acid fractions generate different postprandial patterns. But so do different sugars. Fructose, in particular, is an especially potent agent that magnifies the postprandial patterns. (See Goodbye, fructose.)

The left graphs show the triglyceride effects of adding glucose-sweetened drinks (not sucrose) to the study participants' diets. The right graphs show the triglyceride effects of adding fructose-sweetened drinks.

Note that fructose causes enormous "stacking" of triglycerides, meaning that postprandial chylomicrons and VLDL particles are accumulating. (This study also showed a 4-fold greater increase in abdominal fat and 45% increase in small LDL particles with fructose.)

It means that low-fat salad dressings, sodas, ketchup, spaghetti sauce, and all the other foods made with high-fructose corn syrup not only make you fat, but also magnifies the severity of postprandial lipoprotein stacking, a phenomenon that leads to more atherosclerotic plaque.

Track Your Plaque: Safer at any score

Imagine two people.

Tom is a 50-year old man. Tom's initial heart scan score was 500--a concerning score that carries a 5% risk for heart attack per year.

Harry is also 50 years old. His heart scan score is 100--also a concerning score, but not to the same degree as Tom's much higher score.

Tom follows the Track Your Plaque program. He achieves the 60:60:60 lipid targets; chooses healthy foods, including elimination of wheat; takes fish oil at a therapeutic dose; increase his blood vitamin D level to 60-70 ng/ml, etc. One year later, Tom's heart scan score is 400, representing a 20% reduction from his starting score.

Harry, on the other hand, doesn't understand the implications of his score. Neither does his doctor. He's casually provided a prescription for a cholesterol drug by his doctor, a brief admonition to follow a low-fat diet, and little else. One year later, Harry's heart scan score is 200, a doubling (100% increase) of the original score.

At this point, we're left with Tom having a score of 400, Harry with a score of 200. That is, Tom has twice Harry's score, 200 points higher. Who's better off?

Tom with the score of 400 is better off. Even though he has a significantly higher score, Tom's plaque is regressing. Tom's plaque is therefore quiescent with active components being extracted, inflammation subsiding, the artery in a more relaxed state, etc.

Harry's plaque, in contrast, is active and growing: inflammatory cells are abundant and producing enzymes that degrade supportive tissue, constrictive factors are released that cause the artery to pinch partially closed, fatty materials accumulate and trigger a cascade of abnormal responses.

So it's not just the score--the quantity of atherosclerotic plaque present--but the state of activity of the plaque: Is it growing, is it being reduced? Is there escalating or subsiding inflammation? Is plaque filled with degradative enzymes or quiescent?

Following the Track Your Plaque program therefore leads us to the notion that it's not the score that's most important; the most important thing is what you're doing about it. We sometimes say that Track Your Plaque makes you safer at any score.

Triglyceride and chylomicron "stacking"

Continuing the comments started in Grazing is for cattle, here's an interesting study from the Oxford Center for Diabetes, Endocrinology and Metabolism.

Volunteers were fed a test meal breakfast of Rice Krispies, a banana, and a chocolate milkshake (76.4 grams carbohydrates, 51.9 grams fat, 12.2 grams protein). Lunch was served 5 hours later and consisted of a cheese sandwich and a second chocolate milkshake 43.4 grams carbohydrates, 49.6 grams fat, 24.0 grams protein). Frequent blood samples were then assessed over the day. (Don't try this at home: These are obviously very dangerous foods!)

Here's the pattern of triglycerides that was observed (1st dotted vertical line = breakfast, 2nd dotted vertical line = lunch):



Note that triglycerides only begin to decline 3-4 hours after breakfast, only to peak higher after lunch.


Here's the pattern observed for chylomicrons, the "granddaddy" of lipoproteins that derives from intestinal absorption of fatty acids:



Both graphs from Heath RB et al Am J Phyiol Endocrinol Metab 2006.


With chylomicrons, note a similar pattern to triglycerides: Chylomicrons begin to decline at 3-4 hours, only to peak higher after lunch.

This is the first study to examine the effect of sequential meals on such postprandial (after-eating) patterns. But it makes the graphic point that, if insufficient time is permitted between meals, both triglycerides and chylomicrons will "stack" themselves higher and higher. (Chylomicrons are subjected to processing by the enzyme, lipoprotein lipase, to form highly atherogenic, or plaque-causing, chylomicron remnants.)

While not examined in this study, my bet is that "grazing," i.e., eating small meals or snacks frequently, is an extreme instance of triglyceride, chylomicron, and chylomicron remnant stacking. That can only lead to one thing: accelerated heart and vascular plaque.

What is a healthy vitamin D blood level?

When measuring blood levels of vitamin D (as 25-hydroxy vitamin D), what constitutes a desirable level?

There's no study that directly examines this question, no study that enrolled thousands of people and assigned a placebo group and groups receiving escalating doses of vitamin D and/or achieved higher levels of vitamin D, then observed for development of cancer, diabetes, depression, heart disease, multiple sclerosis, osteoporosis, osteoarthritis, etc. Such a study would requires many thousands of participants (particularly to observe cancer and multiple sclerosis incidence), many years of observation, and many tens of millions of dollars. Nope, only a drug company could afford such costs.

So we have to piece together various observations and extrapolate what we believe to be the ideal level of vitamin D. Epidemiologic observations in several cancers (breast, colon, prostate, and bladder) suggest that a 25-hydroxy vitamin D level of 30 ng/ml or higher is desirable (with less cancer incidence above this level). Other data suggest a level of 52 ng/ml or greater is desirable. Unfortunately, much cancer research looked at intake of vitamin D from food and supplement sources, rather than actual blood levels. We also have to factor in the great individual variation in vitamin D metabolism, with a single dose yielding variable blood levels (as much as a 10-fold difference). There's also the variation introduced by vitamin D-receptor variation (genetic polymorphisms).

A new study using vitamin D administration helps chart the desirable levels of vitamin D.

Vitamin D supplementation reduces insulin resistance in South Asian women living in New Zealand who are insulin resistant and vitamin D deficient - a randomised, placebo-controlled trial.

In this New Zealand study, 42 women (23 to 68 years old) were given 4000 units vitamin D, 39 women given placebo. Median 25-hydroxy vitamin D levels increased from 21 nmol/L (8.4 ng/ml) to 75 nmol/L (30 ng/ml). Both HOMA (a measure of insulin sensitivity) and fasting insulin levels improved, with greatest improvement seen at 25-hydroxy vitamin D levels of 80-119 nmol/L (32-47.6 ng/ml) or greater.

We also know that a vacation on a Caribbean beach in a bathing suit will increase vitamin D blood levels to the 80-110 ng/ml range without ill-effect (at least in young people who maintain the capacity to activate vitamin D in the skin, a phenomenon that declines as we age).

So do we really know the truly ideal level of vitamin D to achieve? I believe that, given the above observations, it is reasonable to extrapolate that the ideal vitamin D blood level likely lies somewhere above 50 ng/ml. We also know that vitamin D toxicity (i.e., hypercalcemia) is virtually unheard of until vitamin D blood levels approach 150 ng/ml, and even then is inconsistent. The health benefits of vitamin D supplementation are so tremendous, that I am not willing to wait for the prospective data to explore this question fully. For now, I aim for a blood level of vitamin D of 60-70 ng/ml (150-175 nmol/L).

Grazing is for cattle

Many dietitians and nutritionists advise many people today to "graze," i.e., to eat small snacks every couple of hours. They argue that it blocks the drop in insulin and blood sugar that can trigger greater appetite and claim it can facilitate weight loss.



This is an absurd notion. Humans are not meant to graze. Humans are meant to find a wild boar or other animal, kill it, gorge on the meat, organs, and fat, then revert to berries, roots, leaves, and other foraged foods until the next kill. A human living in the wild does not have a cupboard or refrigerator full of ready-to-eat snacks to graze on.

The several hours after a meal is the most dangerous for creating coronary atherosclerotic plaque, i.e., the post-prandial period. In other words, eat dinner and, for the next 6-12 hours, your intestinal tract degrades the food; food byproducts are absorbed into the blood or lymph system. The blood is literally flooded with the byproducts of your meal.

Postprandial abnormalities are emerging to be a potent, and much underappreciated, means of causing heart disease and atherosclerosis in other vascular territories (especially carotid arteries and thoracic aorta).

Not eating--i.e., the fasting state--for extended periods is good for you. Encouraging people to graze amplifies atherosclerotic risk, since it creates an abnormal prolonged postprandial state.

The disastrous results of a low-fat diet

Rob was never that committed to following the program in the first place.

I met Rob because of a modest heart scan score and consultation for a cholesterol abnormality. Rob had been cycled through all the statin agents by his primary care physician, all of which resulted in terrible muscle aches that he found intolerable.

I started out, as usual, characterizing his cholesterol abnormality with lipoprotein testing (NMR):

LDL particle number 1489 nmol/L
LDL cholesterol (Friedewald calculation) 143 mg/dl
Small LDL 52% of total LDL
HDL 50 mg/dl
Triglycerides 82 mg/dl

(LDL particle number is the emerging gold standard for LDL quantification, superior to calculated or Friedewald LDL cholesterol for prediction of cardiovascular events.)

Rob is a busy guy. After only a couple of brief visits, life and work got in the way and Rob let his attentions drift away from heart health. Since the information I provided made little impact on his thinking, he reverted to the low-fat diet his primary care doctor had originally prescribed and that he read about in magazines and food packages. He also ran out of the basic supplements I had advised, including fish oil and vitamin D, and just never restarted them.

A couple of years passed and Rob decided that just poking around on his own might not cut it. So he came back to the office. We repeated his NMR lipoprotein analysis:

LDL particle number 2699 nmol/L
LDL cholesterol (Friedewald calculation) 229 mg/dl
Small LDL 81% of total LDL
HDL 53 mg/dl
Triglycerides 78 mg/dl


Two years of a low-fat diet had caused Rob's LDL particle number to skyrocket by 81%, nearly all due to an explosion of small LDL. Recall that small LDL is more susceptible to oxidation, more inflammation-provoking, more adhesive--the form of LDL particles most likely to cause heart disease.

Also, note that, despite the enormous increase in small LDL, HDL and triglycerides remained favorable. This counters the popular rule-of-thumb offered by some that small LDL is not present when HDL is "normal."

Low-fat diets as commonly practiced are enormously destructive. In Rob's case, a low-fat diet caused both calculated Friedewald LDL as well as LDL particle number to increase dramatically. In many other people, low-fat diets increase calculated Friedewald LDL modestly or not at all, but cause the more accurate LDL particle number to increase significantly, all due to small LDL.

I'm happy to say that, once Rob witnessed how far wrong he could go on the wrong program, he's back on Track. (Sorry, pun intended.) He has resumed his supplements and eliminated the food triggers of small LDL--wheat, cornstarch, and sugars.

Dr. David Grimes reminds us of vitamin D

In response to the Heart Scan Blog post, Fish oil makes you happy: Psychological distress and omega-3 index, Dr. David Grimes offered the following argument.

Dr. Grimes is a physician in northwest England at the Blackburn Royal Infirmary, Lancashire. He is author of the wonderfully cheeky 2006 Lancet editorial, Are statins analogues of vitamin D?, questioning whether the benefits of statin drugs simply work by way of increased vitamin D blood levels.


There is a fashionable interest in Omega-3 fatty acids, and these become equated with fish oil.

But fish oil is much more. Plankton synthesise the related squalene (shark oil) which, in turn, is converted into 7-dehydrocholesterol (7-DHC). The sun now comes into play and it converts 7-DHC into vitamin D (a physico-chemical process).

Small fish eat plankton, large fish eat small fish, and we eat large fish. So vitamin D passes through the food chain.

This has been a vital source of vitamin D for the the Inuits and also for the Scots and other dwellers of northwest Europe. (Edinburgh is on the same latitude as Hudson Bay and Alaska, further north than anywhere in China). In these locations there is not adequate sunlight energy to guarantee synthesis of adequate amounts of vitamin D, again by the action of sunlight on 7-DHC in the skin.

When the Scots moved from coastal fishing villages to industrial cities such as Glasgow, they became seriously deficient in vitamin D, and so the emergence of rickets. This was followed by a variety of other diseases resulting from vitamin D deficiency: tuberculosis, dental decay, coronary heart disease, and even multiple sclerosis and depression (the Glasgow syndrome).

And so it was with the Inuits. When their diet changed from fish for breakfast, fish for lunch, fish for dinner, they became deficient of vitamin D and they developed diseases characteristic of industrial cities, where there is indoor work for long hours, indoor activities, and atmospheric pollution.

It is the vitamin D component of fish and fish oils that is important.

I recently saw an elderly lady from Bangladesh living in northwest England. I would have expected her to have a very low blood level of vitamin D, as her exposure to the sun was minimal. However the blood level was 47ng/ml, not 4 as expected. She eats oily fish from Bangladesh every day, showing its value as a source of vitamin D with subsequent good health. I expect her blood levels of omega-3 fatty acids would also be high.

But it is unfashionable vitamin D that is important, not fashionable omega-3.

David Grimes
www.vitamindandcholesterol.com


Excellent point. The health effects of omega-3 and vitamin D are intimately intertwined when examining populations that consume fish.

In this study of Inuits, it is indeed impossible to dissect out how much psychological distress was due to reduced vitamin D, how much due to reduced omega-3s. My bet is that it's both. Thankfully, we also have data examining the use of pure omega-3 fatty acids in capsule (not intact fish) form, including studies like GISSI Prevenzione.

Nonetheless, Dr. Grimes reminds us that both vitamin D and omega-3 fatty acids from fish oil play crucial roles in mental health and other aspects of health, and that it's the combination that may account for the extravagant health effects previously ascribed only to omega-3s.

Why does fish oil reduce triglycerides?

Beyond its ability to slash risk for cardiovascular events, omega-3 fatty acids from fish oil also reduce triglycerides.

There's no remaining question that omega-3s do this quite effectively. After all, the FDA approved prescription fish oil, Lovaza, to treat a condition called familial hypertriglyceridemia, an inherited condition in which very high triglycerides in the 100s or 1000s of milligrams typically develop.

The omega-3 fraction of fatty acids are unique for their triglyceride-reducing property. No other fraction of fatty acids, such as omega-6 or saturated, can match the triglyceride-reducing effect of omega-3s.

But why does fish oil reduce triglycerides?

First of all, what are triglycerides? As their name suggests, triglycerides consist of three ("tri-") fatty acids lined up along a glycerol (sugar) "backbone." Triglycerides are the form in which most fatty acids occur in the bloodstream, liver, and other organs. (Fatty acids, like omega-3, omega-6, mono- or polyunsaturated, or saturated, rarely occur as free fatty acids unbound to glycerol.) In various lipoproteins in the blood, like LDL, VLDL, and HDL, fatty acids occur as triglycerides.

Of all lipoproteins, chylomicrons (the large particle formed through intestinal absorption of fatty acids and transported to the liver via the lymph system) and VLDL (very low-density lipoprotein, very low-density because they are mostly fat and little protein) particles are richest in triglycerides. Thus, we would expect that omega-3s exert their triglyceride-reducing effect via reductions in either chylomicrons or VLDL.

Indeed, that seems to be the case. The emerging evidence suggests that omega-3 fatty acids from fish oil reduce triglycerides through:

--Reduced VLDL production by the liver (Harris 1989)
--Accelerating chylomicron and VLDL elimination from the blood
--Activation of peroxisome proliferator-activated receptor gamma (PPAR-gamma)--Omega-3s ramp up the cellular equipment used to convert fatty acids to energy (oxidation) (Gani 2008)

Combine omega-3 fatty acids from fish oil with wheat elimination and you have an extremely potent means of reducing triglycerides. Read a previous Heart Scan Blog post here to read how a patient reduced triglycerides 93.5% from 3100 mg/dl to 210 mg/dl in just a few weeks using fish oil and wheat elimination.

Is there something fishy about fish oil?

To be sure, there's plenty of misinformation out there about fish oil. Take a look at the swill that passes for health information on Woman's Day: On Call with Dr. Sandy: Fish Oil and Mercury:



Reader Question: My doctor recommended that I take a fish oil supplement, but I'm concerned about mercury. Is there any way to tell which brands are lowest in mercury content?



On Call Response: When it comes to OTC supplements, the answer is no. Though most fish oil supplements sold by major brands are probably safe, there's really no way to tell what's in the bottle or how much mercury it might contain.




Perhaps Dr. Sandy should read the many independent analyses performed on nutritional supplement fish oil, including those at Consumer Lab and Consumer Report before she offers her blind criticisms.

Lovaza vs fish oil supplements?

Lovaza is the FDA-approved form of fish oil that is available only by prescription. It contains 842 mg of the omega-3 fatty acids, EPA and DHA, per capsule.

The FDA application for Lovaza is viewable here on the FDA website. Interestingly, while there is plenty of the usual regulatory gobbledy-gook about toxicology, dose escalation, and efficacy in the extensive documentation, there is little said about the issue of contamination.

In other words, critics of nutritional supplement fish oil harp on the possibility of contamination with mercury and pesticide residues, like dioxin and PCBs (polychlorinated biphenyls). Yet there is virtually nothing about these same issues in the FDA application for Lovaza.

Let's take a look at a sample over-the-counter fish oil product. Our friends at PharmaNutrients (a new Track Your Plaque partner for nutritional supplements) have a fish oil product called PharmaNutrients" Cardio. Here's an independent analysis of the Cardio product (per 1000 mg fish oil capsule):

EPA content: 566.1 mg
DHA content: 216.6 mg
(Total EPA + DHA 782.7 mg)

Cardio passed all tests for peroxides, PCBs, dioxin, furans, dioxin-like PCBs, and heavy metals (arsenic, cadmium, lead, mercury) using criteria at least 60% more stringent than European Commission (EC) standards (EC standard <2 picograms/gm for dioxins and furans, PharmaNutrients <1 picograms/gm; EC standard <10 picograms/gm for dioxin-like PCBs, PharmaNutrients <3 picograms/gm). PCBs levels in particular are less than 0.009 ppm, 90% below the industry-wide purity standard of 0.09 ppm. Likewise, mercury is >90% lower than European Commission standards.

In other words, this over-the-counter "pharmaceutical grade" fish oil has virtually nothing but omega-3 fatty acids.

Interestingly, the PharmaNutrients fish oil capsule also contains the third omega-3 fatty acid, docosapentaenoic acid (DPA), a neglected form that some authorities have proposed has superior cardiovascular protective properties over eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). If DPA is included in the analysis, PharmaNutrient's Cardio contains a total of 900 mg omega-3 fatty acids per capsule.

At some point, I'd like to see a head-to-head comparison not just on purity grounds, since I am convinced that high-quality products like Cardio can match or exceed the purity of prescription fish oil, but on efficacy in raising omega-3 blood levels, the omega-3 index. (The omega-3 index is a predictor of heart attack and sudden cardiac death--the higher, the better.) My prediction: High-quality fish oil supplements will match or exceed prescription fish oil.

More on blood sugar

Take any of the following foods:

One chicken breast
Quarter-pound ground beef
6 oz salmon steak
½ cup raw almonds
3 eggs scrambled in olive oil

How much is blood sugar increased by any item in the above list?

If you said virtually zero, you’re correct. Eat any of these foods, regardless of portion size, and blood sugar won’t change substantially. If you started with a blood sugar of, say, 90 mg/dl, 1-2 hours later it would be 90 mg/dl. It might go up or even down a few milligrams, but for all practical purposes it remains substantially unchanged.

How much is blood sugar increased by the foods in this list:

2 slices multigrain bread
1 whole wheat bagel
4 oz high-fiber breakfast cereal
2 whole grain pancakes, 2 oz maple syrup

The foods in this list are a different story from the first. Depending on your body weight, exercise habits, and other factors, a typical blood sugar response in an otherwise healthy non-diabetic person would be 120 mg/dl to 160 mg/dl. In someone with diabetes, it could easily exceed 200 mg/dl.

That isn’t good. Large blood sugar excursions to 140 mg/dl have been clearly associated with greater risk for heart attack, progression to diabetes, inflammatory responses, and other adverse health effects. In fact, blood sugars as low as 100 mg/dl after eating have been associated with increased cardiovascular risk.

Then why are the USDA, American Heart Association, the American Dietetic Association, and the American Diabetes Association telling us to eat more of the foods that shoot blood sugar up to such high levels? “Eat more healthy whole grains”?

To see how much the issue of exaggerated blood sugars after eating applies to you, a simple blood sugar check 1-2 hours after eating can show you. Either your doctor can have the test drawn or you can purchase your own inexpensive glucose meter (e.g., Walmart, Wagreens).

My prediction: You will be very surprised at blood sugar responses after common foods, including “healthy whole grains.” And, by the way, keeping blood sugar excursions to a minimum will facilitate weight loss.

To get low-carb right, you need to check blood sugars

Reducing your carbohydrate exposure, particularly to wheat, cornstarch, and sucrose (table sugar), helps with weight loss; reduction of triglycerides, small LDL, and c-reactive protein; increases HDL; reduces blood pressure. There should be no remaining doubt on these effects.

However, I am going to propose that you cannot truly get your low-carb diet right without checking blood sugars. Let me explain.

Carbohydrates are the dominant driver of blood sugar (glucose) after eating. But it's clear that we also obtain some wonderfully healthy nutrients from carbohydrate sources: Think anthocyanins from blueberries and pomegranates, vitamin C from citrus, and soluble fiber from beans. There are many good things in carbohydrate foods.

How do we weigh the need to reduce carbohydrates with their benefits?

Blood sugar after eating ("postprandial") is the best index of carbohydrate metabolism we have (not fasting blood sugar). It also provides an indirect gauge of small LDL. Checking your blood sugar (glucose) has become an easy and relatively inexpensive tool that just about anybody can incorporate into health habits. More often than not, it can also provide you with some unexpected insights about your response to diet.

If you’re not a diabetic, why bother checking blood sugar? New studies have documented the increased likelihood of cardiovascular events with increased postprandial blood sugars well below the ranges regarded as diabetic. A blood sugar level of 140 mg/dl after a meal carries 30-60% increased (relative) risk for heart attack and other events. The increase in risk begins at even lower levels, perhaps 110 mg/dl or lower after-eating.

We use a one-hour after eating blood sugar to gauge the effects of a meal. If, for instance, your dinner of baked chicken, asparagus brushed with olive oil, sauteed mushrooms, mashed potatoes, and a piece of Italian bread yields a one-hour blood sugar of 155 mg/dl, you know that something is wrong. (This is far more common than most people think.)

Doing this myself, I have been shocked at the times I've had an unexpectedly high blood sugar from seemingly "safe' foods, or when a store- or restaurant-bought meal had some concealed source of sugar or carbohydrate. (I recently had a restaurant meal of a turkey burger with cheese, mixed salad with balsamic vinegar dressing, along with a few bites of my wife's veggie omelet. Blood sugar one hour later: 127 mg/dl. I believe sugar added to the salad dressing was the culprit.)

You can now purchase your own blood glucose monitor at stores like Walmart and Walgreens for $10-20. You will also need to purchase the fingerstick lancets and test strips; the test strips are the most costly part of the picture, usually running $0.50 to $1.00 per test strip. But since people without diabetes check their blood sugar only occasionally, the cost of the test strips is, over time, modest. I've had several devices over the years, but my current favorite for ease-of-use is the LifeScan OneTouch UltraMini that cost me $18.99 at Walgreens.

Checking after-meal blood sugars is, in my view, a powerful means of managing diet when reducing carbohydrate exposure is your goal. It provides immediate feedback on the carbohydrate aspect of your diet, allowing you to adjust and tweak carbohydrate intake to your individual metabolism.

Food sources of vitamin K2: Reprint

For some reason, my December, 2007, Heart Scan Blog post, Food sources of vitamin K2, has been receiving a lot of traffic.

I therefore reprint the vitamin K2 post below.





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

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

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

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

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

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















Feta cheese

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

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



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

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

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





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

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

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

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

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

Family lessons

Lou was recovering from his 3rd bypass operation. This third go-round left him weaker, slower, less quick on the rebound. In fact, he was lucky to have survived.

At 71 years old, Lou went a good 15 years since his second bypass, another 10 years prior to his first bypass at age 46.

In the days immediately following Lou's bypass, I had a chance to talk to his son, who stayed at his Dad's bedside while Lou struggled through post-op recovery.

"Did your Dad tell you about why this has happened, what caused his heart disease?" I asked.

"Sort of. He just said I should get checked," Lou's son, Aaron, replied.

"Did he mention the lipoprotein(a) pattern he has?"

"No. He never mentioned anything like that. He just said to get checked."

That's how it gets played out more often than not: Mom or Dad has a heart attack, stents, or (3rd) bypass, the children are told to get checked. Getting "checked" assumes that the doctor knows what to check for.

In Lou's case, the reason why he was in the hospital getting his 3rd (and final) bypass was lipoprotein(a), along with genetically-determined small LDL particles, low HDL, a postprandial (after-eating) disorder, hypertension, and borderline diabetes, not to mention vitamin D deficiency, omega-3 fatty acid deficiency, and marginal thyroid function. (Lou, a retired city employee, had showed only marginal interest in correcting these patterns. While he accepted medications, he proved unwilling to engage in the diet and nutritional supplement strategies required to correct his patterns.)

So Lou's 3rd bypass operation provided a moment of reflection for Aaron to ask: "Could I share the fate of my Dad?" With Lou's combination of genetic patterns, there was at least a 75% likelihood that he did. Sadly, going to his doctor would likely yield little more than a cholesterol panel, a question about smoking, and a prescription for Lipitor.

Just getting "checked" would be, more than likely, a recipe for disaster for Aaron: heart disease in his 40s or 50s. That's why you need to take control over this sad state of affairs and ask--no, insist--that an effort be made to determine whether you might share your parents' fate.

Look like Jimmy Stewart


"This diet works great," Don declared. "But I think I've lost too much weight."

At 67 years old and 5 ft. 11 inches, Don began the program weighing 228 lbs (BMI 31.9). Because of high triglycerides, high blood sugar, high c-reactive protein, and excessive small LDL, I instructed Don to eliminate all wheat products from his diet, along with cornstarch and sweets. His intake of lean meats, eggs, vegetables, oils, raw nuts, etc. was unlimited.

Don now weighed 194 lbs, down 34 lbs over 6 months (BMI 27.1). Triglycerides, blood sugar, blood pressure, and well-being had improved dramatically; small LDL, however, had dropped only 30%--still room for improvement.

"My friends say I'm too skinny. They ask if I have cancer!"

I've heard this many times: Someone loses weight in a relatively short period of time and friends and family tell you you're too skinny. "It must be cancer. Nobody loses weight like that."

Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man. But Americans have put on so much weight that the prevailing view of what constitutes "normal" weight has been revised upward. Normal is closer to what we see in old movies from the 1940s and '50s with people like Jimmy Stewart and Donna Reed. That's what we are supposed to look like.

So Don actually remains mildly overweight but is judged as "too skinny," or even cancer-ridden, by friends and family.

Ignore such comments. As you lose pounds and approach a truly desirable weight, realize that you are returning to the normal state, not the vision of "normal" now held by most Americans.

Getting vitamin D right

Vitamin D is, without a doubt, the most incredible "vitamin"/prohormone/neurosteroid I have ever encountered. Frankly, I don't know how we got anything accomplished in health pre-D.

Unfortunately, people I meet rarely take their vitamin D in a way that accomplishes full restoration of vitamin D blood levels. It really isn't that tough.

Here's a list of common tripping points with vitamin D:

"I take vitamin D: 1000 units a day."
This is probably the most common mistake I see: Taking a dose that is unlikely to yield a desirable blood level. (We use 60-70 ng/ml of 25-hydroxy vitamin D as our target.) Most men and women require 6000 units per day to achieve this level. There is substantial individual variation, however, with an occasional person needing much more, a rare person requiring as little as 1000 units.


"I bought some vitamin D on sale. They were white tablets."
Time and again, patients in my office who initially have had successful vitamin D replacement, despite being reminded that only oil-based forms should be taken, switch to tablets. While they initially showed a 25-hydroxy vitamin D blood level, for instance, of 67 ng/ml on 8000 units per day with an oil-based capsule, they switch to a tablet form and the next blood level is 25 ng/ml. In other words, tablets are very poorly or erratically absorbed.

I have had people use tablets successfully, however, by taking their vitamin D tablets with a teaspoon of oil, e.g., olive oil. Oil is necessary for full absorption.


"I'm going to Florida. I'll stop my vitamin D because I'm going to lay in the sun."
Wrong. 90% of adults over 40 years old have lost the majority of their ability to activate vitamin D in the skin. A typical response might be an increase in blood level from 25 to 35 ng/ml--a 10 ng increase with a dark brown tan.

There is an occasional person who, with sun exposure, increases blood levels substantially. This can occur in both fair-skinned and dark-skinned people, though I've never seen it happen in an African-American person. The occasional person who maintains the ability to convert vitamin D with sun exposure, or young people, should seasonally adjust their vitamin D dose, e.g., 6000 units winter, 3000 units summer, or some other regimen that maintains desirable blood levels. You can see that monitoring blood levels (we check levels every 6 months for the first 2 years) is crucial: You cannot know what your vitamin D needs are unless you assess 25-hydroxy vitamin D levels.


"I drink plenty of milk. I don't think I need to take vitamin D."
Oh, boy. This is so wrong on so many levels.

First of all, no adult should be drinking plenty of cow's milk. (A discussion for another day.) Second of all, cow's milk averages 70 units of vitamin D, often the D2 form (ergocalciferol), per 8 oz. Even if the FDA-mandated 100 units per day were present, an average adult dose of 6000 units would require 60 glasses of milk per day. Can you say "diarrhea"?

Likewise, other food sources of vitamin D, such as fish (300-400 units per serving) and egg yolks (20 units per yolk), are inadequate. This makes sense: Humans are not meant to obtain vitamin D from food, but from sun exposure over a large body surface area. And this is a phenomenon that is meant to occur only in the youthful, ensuring that nature takes its course and us older folks get old and make way for the young (i.e., unless we intervene by taking vitamin D supplements).


"My doctor said that my vitamin D blood level was fine. It was 32 ng/ml."

Let's face it: By necessity, your overworked primary care physician, who manages gout, hip arthritis, migraine headaches, stomach aches, prostate enlargement, H1N1, depression, etc., is an amateur at nearly everything, expert in nothing. Nobody can do it all and get it right. Likewise vitamin D. The uncertain primary care physician will simply follow the dictates of the laboratory form that specifies "30-100 ng/ml" as the "normal" or "reference range." Unfortunately, the laboratory often quotes population distributions of a lab measure, not an ideal or desirable level.

To illustrate the folly of population distributions of a measure, imagine you and I want to know what women weigh. We go to a local mall and weigh several thousand women. We tally up the results and find that women weigh 172 lbs +/- 25 lbs (the mean +/- 2 standard deviations). (That's true, by the way.) Is that desirable? Of course it isn't. Population average or population distribution does not necessarily mean ideal or desirable.


"My husband's doctor said he should take 4000 units per day. So I just take the same dose."
That would be fine if all adults required the same dose. However, individual needs can vary enormously. A dose that is grossly insufficient for one person may be excessive for another. Once again, vitamin D dose needs can be individualized by assessing 25-hydroxy vitamin levels in the blood.


"I don't need to take vitamin D. I already take fish oil."
I suspect this mistaken belief occurs either because people confuse fish oil with cod liver oil, which does contain some vitamin D. (Cod liver oil is not the best source of vitamin D, mostly because of the vitamin A content; also a discussion for another time), or because they've heard that eating fish provides vitamin D. However, fish oil capsules do not contain vitamin D unless it is added, in which case it should be prominently and explicitly stated on the label.


"I don't have to take vitamin D. It's summer."

For most people I know, if it's a bright, sunny July day, where are they likely to be? In an office, store, or home--NOT lying in the sun with a large body surface area exposed. Also, most people expose no more than 5-10% of surface area in public. I doubt you cut the grass in a bathing suit. Because of modern indoor lifestyles and fashion, the majority of adults need vitamin D supplementation year-round.


I advise everyone that gelcap vitamin D is preferable. Some, though not all, liquid drop forms have also worked. Take a dose that yields desirable blood levels. And blood levels of 25-hydroxy vitamin D are ideally checked every 6 months: in summer and in winter to provide feedback on how much sun activation of D you obtain.

If your doctor is unwilling or unable to perform vitamin D testing, fingerstick vitamin D test kits can be obtained from Track Your Plaque.

Jimmy Moore's thyroid adventure

My friend, Jimmy Moore of Living La Vida Low Carb, describes his thyroid experience here.

As Jimmy points out, he was looking for a way to jump-start a 50-lb weight loss. In my experience, low thyroid hormone levels ("hypothyroidism") are an exceptionally common cause for weight gain. Correcting even marginal hypothyroidism can facilitate weight loss, often resulting in 10 or more pounds of weight loss within the first month.

Unfortunately, Jimmy's thyroid hormone panel proved normal: TSH 1.3, thyroid hormones free T3 and free T4 in the mid- to upper-half of the reference range.

I say "unfortunately" because it is really an easy, inexpensive, and benign solution for losing weight. (I don't, of course, wish that Jimmy or anyone else develops a thyroid condition. But it really can provide gratifying weight loss results when thyroid function is low.) Jimmy might consider taking his oral temperature first thing in the morning as another means of assessing the adequacy of thyroid function.

Perhaps you will be luckier than Jimmy and have thyroid dysfunction that can be corrected and jump-start your weight loss program. Fingerstick thyroid test kits like the one Jimmy used are available here from Track Your Plaque.
