Are there any alternatives to niacin?

10. September 2006 William Davis (0)

In the Track Your Plaque program, we tend to rely a great deal on niacin. When used properly, 90-95% of people will do just fine and achieve their lipid and lipoprotein goals with the help of niacin, along with their other efforts.

Unfortunately, around 5% of people simply can't take niacin without intolerable "hot flush" effects, or occasionally excessive skin sensitivity--itching, burning, etc.

Why does this happen? These 5% tend to be "rapid metabolizers" of niacin, i.e. they convert niacin (nicotinic acid, or vitamin B3) into a metabolite called nicotinuric acid. Nicotinuric acid is the compound responsible for the skin flush. Most people can slow or reduce the effects of nicotinuric acid by:

--Taking niacin with dinner, so that food slow tablet dissolution.

--Taking with plenty of water. Two 8-12 oz glasses usually eliminates the flush entirely in most people.

--Taking with an uncoated 325 mg tablet of aspirin in the first few weeks or months. Eventually, you will need to revert back to a better stomach tolerated dose of 81 mg, preferably enteric coated. But a full 325 mg uncoated can really help in the beginning, or when you have any niacin dose increases, e.g., 500 mg to 1000 mg.

But even with these very effective strategies, some people still struggle. That's when the question arises: Are there any alternatives to niacin?

Well, it depends on why niacin is being used. If you and your doctor are using niacin for:

Raising HDL--Then weight loss to your ideal weight; reduction of processed carbohydrates, especially wheat products; avoidance of hydrogenated ("trans") fats; a glass or two of red wine per day; dark chocolates (make sure first ingredient is chocolate or cocoa, not sugar), 40 gm per day; fish oil; exercise; other prescription agents (fibrates like Tricor; TZD agents for diabetes; cilostazol (Pletal)). Niacin is by far the most effective agent of all, but, if you're intolerant, raising HDL is still possible through a multi-faceted effort.

Reduction of small LDL--The list of effective strategies is the same as for raising HDL, but add raw almonds (1/4-1/2 cup per day), oat bran and other beta-glucan rich foods like oatmeal. Reduction of processed carbohydrates is especially important to reduce small LDL.

Reduction of Lipoprotein(a)--This is a tricky one. For men, testosterone and DHEA are effective alternatives; for women, estrogen and perhaps DHEA. Hormonal preparations of testosterone and estrogen are stricly prescription; DHEA is OTC. I have not seen the outsized benefits on lipoprotein(a) claimed by Rath et al by using high-dose vitamin C, lysine, and profile, unfortunately. We are clearly in need of better alternatives to treat this difficult and high-risk disorder.

Reduction of triglycerides/VLDL/IDL--I lump these three together since they all respond together. If you're niacin intolerant, maximixing your fish oil can be crucial for reduction of these patterns using doses above the usual starting 4000 mg per day (providing 1200 mg EPA+DHA). Reduction of processed carbohydrates, eimination of processed foods that contain high-fructose corn syrup, and weight loss to ideal weight are also very effective. "Soft" strategies with modest effects include green tea (>6 cups per day) or theaflavin 600-900 mg/day; raw nuts like almonds, walnuts, and pecans; exercise; soy protein.

Reduction of LDL--Lots of alternatives here including oat bran (3 tbsp per day), ground flaxseed (3 tbsp per day), soy protein (25 grams per day), Benecol butter substitute (for stanol esters), soluble fibers like pectin, psyllium, glucomannan; raw nuts like almonds, walnuts, and pecans.

In future, should torcetrapib become available (by prescription), this will add to our available tools for these areas when niacin can't be used. Until now, the alternatives to niacin depend on what you and your doctor are trying to achieve. In the vast majority of cases, HDL, small LDL, triglyceride, etc. goals for heart scan score control can be achieved, even when niacin is not well tolerated.

Is flaxseed oil a substitute for fish oil?

9. September 2006 William Davis (3)

This question comes up so frequently that it's worth going over.

Flaxseed oil is a wonderful oil rich in linolenic acid, which may provide health benefits all by itself. Some authorities have speculated that the substantial reduction in heart attack seen in the Lyon Heart Study, the study that demonstrated the healthy power of the Mediterranean diet, is due to linolenic acid.

Flaxseed oil is also rich in monounsaturates and low in saturates, both desirable qualities. Of course, I'm talking here about flaxseed oil, to be distinguished from flaxseed , which are the intact seeds. The seeds themselves also contain the same oils, but contain other components, specifically lignan, a plant fiber with suspected health benefits like reduction in cancer risk.

Despite all flaxseed oil's wonderful properties, it is definitely not a substitute for fish oil. Why do we use fish oil for our coronary plaque control program (trying to reduce your heart scan score)? Several reasons. Fish oil:

--Dramatically reduces triglycerides, usually by 50% or more.
--Dramatically reduces specific lipoprotein classes like VLDL
--Dramatatically reduces, often eliminates, abnormal postprandial (after-eating) lipoprotein patterns, like IDL (intermediate-density lipoprotein)
--Has been conclusively shown to reduce risk of heart attack and death from heart attack (GISSI Prevenzione Trial).
--Has been shwon to reduce risk of stroke.
--Modifies blood clotting parameters, particularly a 20% reduction in fibrinogen.

Flaxseed oil, or linolenic acid concentrate for that matter, do not accomplish any of these effects, all crucial if you are to gain control over your coronary plaque.

Flaxseed oil and flaxseed remain wonderful nutritional agents for their own reasons. But they will not substitute for fish oil in your program. Only fish oil--the real thing--does the job.

If you have coronary artery disease . . . do you know why?

9. September 2006 William Davis (0)

This conversation is aimed primarily at non-followers of the Track Your Plaque program, because if you were a follower, you’d already know the answer!

I saw a woman in the hospital today. She’d just survived her second heart attack one week earlier. At 51 years old, she was understandably shaken, perhaps terrified. She felt that her future was uncertain and, in fact, had discussed with her husband what he should do to prepare for a future without her.

One week earlier, she’d received three stents that successfully aborted her heart attack. But, as is always the case, the modest delays of ambulance transport, the emergency room preliminaries, then of mobilizing an available cardiologist and catheterization laboratory team, totaled nearly two hours before her stent procedure. Inevitably, a moderate amount of damage had been done to her heart.

Her first “event” had been very similar: very little warning, then 911 and the flurry of activity. Both times, the cardiologists (two different physicians) complimented the patient on her prompt action. Both also called her heart attacks “close calls”.

She defied the odds with two near-death events. So, when I met her a week after her last heart attack, I asked an obvious question: “Has anyone told you why you’re having these heart attacks?”

She looked completely puzzled at first. She then said, “No, not really. I just assumed it was genetic. My mother went through the same thing when she was my age. But she didn’t get as far as I have, since they didn’t have these procedures back then.”

To me, this seems inexcusable: This woman had experienced two brushes with death and no doctor had established a cause. Could this woman’s belief be true, that it’s just genetic?

While there are, indeed, genetic causes for heart disease, the vast majority of these genetic causes are 1) identifiable, and 2) correctable. Genetic does not necessarily mean hopeless. It just means that the usual equation of heart disease risk management (heart disease = LDL cholesterol = need for Lipitor) has limited value. It would be like giving penicillin to people for any and all infections. It will work occasionally, but it will fail miserably in a great many cases. Treating LDL cholesterol with statin drugs is just like that.

Perhaps this woman has lipoprotein(a), a serious genetic trait that predicts heart disease at a young age and is largely unaffected by statin drugs. Or, she may have a severe excess of small LDL, only partially suppressed by statins. If she has the combined pattern of lipoprotein(a) and small LDL, that means she has two statin-unresponsive and significant genetic traits. But they respond to niacin, specific nutritional strategies, and several other agents.

The message: If you have coronary disease, you need to insist on knowing why. “It’s genetic” is not an acceptable answer. “There’s no proof of any heart disease causes beyond cholesterol” is also nonsense. “Everyone gets heart disease, or “hardening of the arteries”, eventually. You just got it a little before everyone else” is also patently ridiculous.

Identifying the causes of your coronary disease (or coronary plaque if you’ve had a CT heart scan) is the first step in developing a program of treatment that provides you with control over this disease.

Have you tried inulin yet?

8. September 2006 William Davis (0)

If you haven't yet tried it to facilitate weight loss, it's really worth giving the new inulin-containing product, Fiber Choice "Weight Management", a try.

Recall (from a prior Heart Scan Blog) that inulin is a vegetable-based fiber found in celery, green peppers, etc. that, when exposed to water, expands to many times original volume. This simple phenomenon yields satiety--a feeling of fullness.

The manufacturer of the product has also added green tea, which has been shown in two small clinical studies to enhance weight loss, though by a different route.

We've been advising patients to chew two of the strawberry flavored tablets one hour before every meal (or with breakfast if you eat immediately in the morning). You'll be satisfied with less food and you'll experience less intense food cravings.

Though no one so far has achieved a huge drop in weight, it does seem to enhance a slow, gradual weight loss larger than achieved by diet and exercise alone. And it's very safe and inexpensive. If you give it a try to help you lose weight, let us know what kind of results you've obtained.

More on Vitamin D

6. September 2006 William Davis (0)

If you haven't done so already, you should subscribe to Dr. John Cannell's free newsletter on vitamin D issues. His newest issue is available at:

http://www.vitamindcouncil.com/newsletter/2006-aug.shtml

A sign-up to subscribe is available on the same page.

I continue to be shocked and amazed at the prevalence and magnitude of vitamin D deficiency in the people I see every day. It's been a beautiful summer with very little rain. Most days have been in the 70-80 degree range--very comfortable to be outdoors in the sun and getting skin expoxure to activate vitamin D in the skin.

Yet, in the vast majority of people I see, summer blood levels of vitamin D are virtually indistinguishable from winter levels. Both hover around the 30 ng/ml range. Summer levels in Wisconsin people seem to be no more than 10 ng/ml higher than winter levels. This remains true even in people who spend a lot of their day outdoors gardening, walking, etc. wearing shorts and a short-sleeved shirt, i.e. with plenty of skin surface area exposed.

I'm at a loss to explain precisely why. Yes, it is Wisconsin. But a direct sun overhead, 75 degree day should be providing plenty of sun. My suspicious is that a combination of factors are at work: people are not spending as much time outdoors as they claim; they often seek shade; use sunscreen; and they're overweight. (Excess weight decreases vitamin D blood levels dramatically, yet another reason not to get fat!)

Why not just get "perfect" lipids and call it a day?

5. September 2006 William Davis (0)

What if you achieved the Track Your Plaque lipid targets: LDL cholesterol 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl?

After all, these are pretty stringent standards. Compared to national guidelines (the ATP-III Guidelines of the National Cholesterol Educational Panel), the Track Your Plaque 60-60-60 goals are laughably ambitious. There's a lot of wisdom hidden in those numbers. The triglyceride level of 60, for instance, is a level at which triglycerides become essentially unavailable for formation of triglyceride-containing lipoprotein particles such as small LDL and VLDL.

If you get to the 60-60-60 target, isn't that good enough? What if you just held your values there and went about your business? Will coronary plaque stop growing and will your CT heart scan score stop increasing?

Sometimes it will. But, unfortunately, many times it will not. The experience generated through clinical trials bear this out. Studies like the St. Francis Heart Study and the BELLES Trial both showed that just reducing LDL cholesterol is insufficient to stop plaque growth. Beyond the Track Your Plaque experience, there's no clinical trial experience that shows whether the 60-60-60 approach does any better.

In our experience, achieving 60-60-60 is indeed better than just reducing LDL. That makes sense. Just raising HDL from the average of 42 mg/dl for a male, 52 mg/dl for a woman adds advantage. Compound this with triglyceride reduction from the plaque-creating equation, and you've doubled success.

But there's even more. What if you had hidden patterns not revealed by conventional lipids? How about lipoprotein(a)? Small LDL? Postprandial (after-eating) abnormalities? Hypertensive effects (more common than you think)!

In 2006, stopping the increase in your heart scan score is, for most of us, not just a matter of taking Lipitor or its equivalent and sitting back. For nearly all of us, stopping the progression of your score is a multi-faceted effort.

Hospitals: Then and Now

2. September 2006 William Davis (0)

It's 1920. The hospital in your city is a facility run by nuns or the church. It's a place for the very ill, often without hope of meaningful treatment, but nonetheless a place where surgeries take place, babies are born, the injured and chronically ill can find care. No one has health insurance and there's no Medicare. Everyone pays what they can. The hospital is accustomed to doling out plenty of care without compensation. For that reason, they welcome donations and sometimes will build new additions or other facilities in honor of a major donor.

Volunteeers are common, since the wards are understaffed and generally suffering from a shortage of trained nurses and personnel associated with the church. Drugs, such as they are, are often prepared from basic ingredients in the hospital pharmacy. Product representatives hawking medicines and devices are virtually unheard of.

Though their therapeutic tools are limited, the physicians are a proud group, dedicating their careers to healing. The majority of the medical staff volunteer large portions of their time to care for the poor who come to the hospital with very advanced stages of disease: metastatic tumors, advanced heart failure, debilitating strokes, overwhelming septicemia, etc.

Hospitals are usually governed by a board of clergy and physicians who make decisions on how to apply their limited resources and continually seek charitable donations.

Fast forward to present day: Hospitals are high-tech, professional facilities with lots of skilled people, complicated equipment,and capable of complex procedures. While they still house people with advanced illnesses, the floors are also filled with people with much earlier phases of disease. In general, they do a good job, with quality issues scrutinized by a number of official agencies to police practices, incidence of hospital-related infections, medication errors, care protocols, etc.

The hospital of 2006 is a more more effective place than the hospital of 1920. But its aims and operations are different, also. Though some churches are still involved in hospitals, more and more are owned by publicly-traded companies that answer to shareholders--shareholders who want share value to increase. Though donations are still sought, much of the revenues are obtained by concentrating on profitable, large-ticket procedures. More procedures are often generated by advertising.

Because they operate to generate profits, several hospitals in a single city or region compete with one another. The 21st century has therefore witnessed the phenomenon of hospital-owned physicians: more and more practicing physicians are employees of their hospital. That way, the physician brings all his patients and procedures to his hospital, not to a competitor. The top of the funnel is the primary care physician, who tends to see all disease when it first occurs. The primary care physician then sends the patient to the specialist, who is obliged (by contract) to perform his/her procedure in the hsopital paying their salary.

Representatives from companies manufacturing and selling expensive hospital equipment and drugs are everywhere, falling over themselves to gain attention of the physicians using their equipment and the hospital buyers who make purchasing decisions. Millions of dollars can be transacted with just one sale.

The number of volunteers has dwindled. The poor and uninsured are commonly diverted elsewhere, often to a government-funded, and often second-rate, institution. Hospitals measure success by comparing annual revenues and numbers of major procedures.

The hospital of 2006 is a vastly different place than 1920. If you're expecting charitable treatment, compassion, and selfless care, you're in the wrong century. In 2006, the hospital is a business. You don't expect charitable treatment at Wal-Mart or from your car dealer. Don't expect it from your hospital. They are businesses and you are a customer. Recognize this fact, lose the nostalgia for the hospitals of yesterday, and a lot more will become clear to you.

The dreaded small LDL particle

1. September 2006 William Davis (0)

Brian is a 59-year old landscape architect whose starting CT heart scan score was 276.

Brian's food choices at the start were deplorable: a pound of sausage per week, sometimes more; butter on anything and everything; up to two pounds of cheese per week; hot dogs; etc. His lipoproteins were accordingly just as miserable: low HDL, high triglycerides, excessive (postprandial, or after-eating) IDL. Small LDL was a particularly stand-out pattern, with 95% of all LDL particles in the small category.

Brian made a dramatic turnaround in lifestyle and corrected all of his patterns--except for small LDL. After one year, small LDL still occupied 95% of all LDL particles, even though the quantity of LDL had been reduced. In order to help convince Brian that correction of his small LDL was going to be necessary to achieve control oover coronary plaque, I suggested that he undergo another heart scan. His score: 435, or a 57% increase.

Each day that passes, I gain more and more respect for small LDL as a cause for coronary plaque growth. Conventional thought among lipid experts is that small LDL should no longer be a factor if total LDL (e.g., LDL particle number) is reduced. But our experience suggests otherwise: when small LDL persists, we tend to see continued, sometimes frightening, plaque growth.

I therefore asked Brian to intensify his efforts: additional weight loss off his somewhat prominent abdomen (since visceral fat increases small LDL), further reduce wheat products and processed carbohydrates, increase niacin (to 1500 mg per day), and use more raw almonds and oat bran.

Don't let small LDL get the best of you. It is a nasty, sometimes persistent abnormality that has impressive effects on plaque growth.

Winning Through Intimidation

31. August 2006 William Davis (0)

Do you remember the book, Winning Through Intimidation by author Robert J. Ringer?

In his 1984 bestseller, author Ringer details how to succeed in business by overwhelming clients and competition by appearing hugely successful and powerful. Rather than a business card, he'd hand out an elegant book to represent himself. He'd show up in a limousine to a meeting, even when he could barely afford it. He used these tactics, even when he was a small-fry, in commercial real estate and built a successful business following such techniques.

This reminds me a lot of what happens in conventional medical practice: The large and successful hospitals, filled with trained staff and technology, exude legitimacy and success. How can they possibly be wrong? Such overwhelming know-how and multiple levels of expertise mustbe right!

Let's be grateful that we do have access to such high-tech, capable care. Unfortunately, just as Mr. Ringer used deceptive practices to appear something he wasn't, this is also true in hospitals. Not all physicians have your best interests in mind. Their principal concern is how profitable your care can be for them--can you be persuaded to have your stent, bypass, etc.. After all, look around you: Aren't all this equipment and personnel impressive? Aren't you intimidated?

The patient that most recently drove home this issue for me recently was a smart and capable executive who came in for consultation. He had been told by his internist that a surgery (to replace his aorta, a HUGE procedure) was probably necessary. In my view, it was not--his process was simply not that far progressed. The risks for danger over the next several years was virtually nil. Unfortunately, this man, now confused and worried, sought an opinion from the chief of thoracic surgery (in the usual white coat and with professorial demeanor, I'm sure) in a major metropolitan hospital (in Chicago), who promptly rushed him off to the operating room.

The pathology report, cleverly not mentioned in any other of the hospital documentation, showed what I had suspected: this man had mild disease that wasn't even close to requiring surgery. But, with all that technology, $100,000 or so of costs, chief of surgery who looked the part, etc.--they must be right!

Robert Ringer's concepts only ring too true for hospitals and some of the unscrupulous physicians in practice. Don't allow yourself to be intimidated.

Krill oil: Do the math

21. Maiu 2013 William Davis (0)

The manufacturers of krill oil claim that the phospholipid form of omega-3 fatty acids, EPA and DHA, enhance their absorption. There are indeed some data to that effect:

Here are some representative krill oil preparations available on the market:

MegaRed Krill Oil:
EPA 50 mg
DHA 24 mg
Total omega-3s (EPA + DHA + other forms) 90 mg
Price: $28.99 for 60 softgels

Source Naturals (a fine company otherwise, by the way):

EPA 150 mg
DHA 90 mg
Total omega-3 fatty acids 300 mg
Price: $24.99 for 60 softgels

Alright, let's do some simple math:

Average volume of blood in the human body (all components): 5000 cc
Percentage of red blood cells (RBCs) by volume: 45%
Total volume RBCs: 2250 cc
Percentage of total volume RBCs occupied by fatty acids:

What tests are MORE important than cholesterol?

12. Maiu 2013 William Davis (8)

In the conventional practice of early heart disease prevention, cholesterol testing takes center stage. Rarely does it go any further, aside from questions about family history and obvious sources of modifiable risk such as smoking and sedentary lifestyle.

So standard practice is to usually look at your LDL cholesterol, the value that is calculated, not measured, then--almost without fail--prescribe a statin drug. While there are indeed useful values in the standard cholesterol panel--HDL cholesterol and triglycerides--they are typically ignored or prompt no specific action.

But a genuine effort at heart disease prevention should go farther than an assessment of calculated LDL cholesterol, as there are many ways that humans develop coronary atherosclerosis. Among the tests to consider in order to craft a truly effect heart disease prevention program are:

--Lipoprotein testing--Rather than using the amount of cholesterol in the various fractions of blood as a crude surrogate for lipoproteins in the bloodstream, why not measure lipoproteins themselves? These techniques have been around for over 20 years, but are simply not part of standard practice.

Lipoprotein testing especially allows you to understand what proportion of LDL particles are the truly unhealthy small LDL particles (that are oxidation- and glycation-prone). It also identifies whether or not you have lipoprotein(a), the heritable factor that confers superior survival capacity in a wild environment ("The Perfect Carnivore"), but makes the holder of this genetic pattern the least tolerant to the modern diet dominated by grains and sugars, devoid of fat and organ meats.

--25-hydroxy vitamin D--The data documenting the health power of vitamin D restoration continue to grow, with benefits on blood sugar and insulin, blood pressure, bone density, protection from winter "blues" (seasonal affective disorder), decrease in falls and fractures, decrease in cancer, decrease in cardiovascular events. I aim to keep 25-hydroxy vitamin D at a level of 60 to 70 ng/ml. This generally requires 4000-8000 units per day in gelcap form, at least for the first 3 or so years, after which there is a decrease in need. Daily supplementation is better than weekly, monthly, or other less-frequent regimens. The D3 (cholecalciferol) form is superior to the non-human D2 (ergocalciferol) form.

--Hemoglobin A1c (HbA1c)--HbA1c represents glycated hemoglobin, i.e., hemoglobin molecules within red blood cells that are irreversibly modified by glucose, or blood sugar. It therefore provides an index of endogenous glycation of all proteins of the body: proteins in the lenses of the eyes that lead to cataracts; proteins in the cartilage of the knees and hips that lead to brittle cartilage and arthritis; proteins in kidney tissue leading to kidney dysfunction.

HbA1c provides an incredibly clear snapshot of health: It reflects the amount of glycation you have been exposed to over the past 90 or so days. We therefore aim for an ideal level: 5.0% or less, the amount of "ambient" glycation that occurs just with living life. We reject the notion that a HbA1c level of 6.0% is acceptable just because you don't "need" diabetes medication, the thinking that drives conventional medical practice.

--RBC Omega-3 Index--The average American consumes very little omega-3 fatty acids, EPA and DHA, such that a typical omega-3 RBC Index, i.e., the proportion of fatty acids in the red blood cell occupied by omega-3 fatty acids, is around 2-3%, a level associated with increased potential for sudden cardiac death (death!). Levels of 6% or greater are associated with reduced potential for sudden cardiac death; 10% or greater are associated with reduced other cardiovascular events.

Evidence therefore suggests that an RBC Omega-3 Index of 10% or greater is desirable, a level generally achieved by obtaining 3000-3600 mg EPA + DHA per day (more or less, depending on the form consumed, an issue for future discussion).

--Thyroid testing (TSH, free T3, free T4)--Even subtle degrees of thyroid dysfunction can double, triple, even quadruple cardiovascular risk. TSH values, for instance, within the previously presumed "normal" range, pose increased risk for cardiovascular death; a TSH level of 4.0 mIU, for instance, is associated with more than double the relative risk of a level of 1.0.

Sad fact: the endocrinology community, not keeping abreast of the concerning issues coming from the toxicological community regarding perchlorates, polyfluorooctanoic acid and other fluorinated hydrocarbons, polybrominated diphenyl ethers (PDBEs), and other thyroid-toxic compounds, tend to ignore these issues, while the public is increasingly exposed to the increased cardiovascular risk of even modest degrees of thyroid dysfunction. Don't commit the same crime of ignorance: Thyroid dysfunction in this age of endocrine disruption can be crucial to cardiovascular and overall health.

All in all, there are a number of common blood tests that are relevant--no, crucial--for achieving heart health. Last on the list: standard cholesterol testing.

Cranberry Sauce

21. Nuvenbru 2012 William Davis (3)

Happy Thanksgiving 2012, everyone, from all the staff at Track Your Plaque!

Here’s a zesty version of traditional cranberry sauce, minus the sugar. The orange, cinnamon, and other spices, along with the crunch of walnuts, make this one of my favorite holiday side dishes.

There are 31.5 grams total “net” carbohydrates in this entire recipe, or 5.25 grams per serving (serves 6). To further reduce carbs, you can leave out the orange juice and, optionally, use more zest.

1 cup water
12 ounces fresh whole cranberries
Sweetener equivalent to 1 cup sugar (I used 6 tablespoons Truvía)
1 tablespoon orange zest + juice of half an orange
½ cup chopped walnuts
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
¼ teaspoon ground cloves

In small to medium saucepan, bring water to boil. Turn heat down and add cranberries. Cover and cook at low-heat for 10 minutes or until all cranberries have popped. Stir in sweetener. Remove from heat.

Stir in orange zest and juice, walnuts, cinnamon, nutmeg, and cloves.

Transfer mixture to bowl, cool, and serve.

Apple Cranberry Crumble

18. Nuvenbru 2012 William Davis (0)

Apple, cranberry, and cinnamon: the perfect combination of tastes and scents for winter holidays!

I took a bit of carbohydrate liberties with this recipe. The entire recipe yields a delicious cheesecake-like crumble with 59 “net” grams carbohydrates (total carbs – fiber); divided among 10 slices, that’s 5.9 grams net carbs per serving, a quantity most tolerate just fine. (To reduce carbohydrates, the molasses in the crumble is optional, reducing total carbohydrate by 11 grams.)

Other good choices for sweeteners include liquid stevia, stevia glycerite, powdered stevia (pure or inulin-based, not maltodextrin-based), Truvía, Swerve, and erythritol. And always taste your batter to test sweetness, since sweeteners vary in sweetness from brand to brand and your individual sensitivity to sweetness depends on how long you’ve been wheat-free. (The longer you’ve been wheat-free, the less sweetness you desire.)

Crust and crumble topping
3 cups almond meal
1 stick (8 tablespoons) butter, softened
1 cup xylitol (or other sweetener equivalent to 1 cup sugar)
1½ teaspoons ground cinnamon
1 tablespoon molasses
1½ teaspoons vanilla extract
Dash sea salt

Filling
16 ounces cream cheese, softened
2 large eggs
½ cup xylitol (or other sweetener equivalent to ½ cup sugar)
1 Granny Smith apple (or other variety)
1 teaspoon ground cinnamon
1 cup fresh cranberries

Preheat oven to 350° F.

In large bowl, combine almond meal, butter, sweetener, cinnamon, molasses, vanilla, and salt and mix.

Grease a 9½-inch tart or pie pan. Using approximately 1 cup of the almond meal mixture, form a thin bottom crust with your hands or spoon.

In another bowl, combine cream cheese, eggs, and sweetener and mix with spoon or mixer at low-speed. Pour into tart or pie pan.

Core apple and slice into very thin sections. Arrange in circles around the edge of the cream cheese mixture, working inwards. Distribute cranberries over top, then sprinkle cinnamon over entire mixture.

Gently layer remaining almond meal crumble evenly over top. Bake for 30 minutes or until topping lightly browned.

Biscuits and Gravy

19. Otubru 2012 William Davis (5)

Biscuits and gravy: the ultimate comfort food . . . one you thought you’d never have again!

The familiar dish of breakfast and holiday meals is recreated here with a delicious gravy that you can pour over piping hot biscuits. Because it contains no wheat or other unhealthy thickeners like cornstarch made with “junk” carbohydrates, there should be no blood sugar or insulin problems with this dish, nor joint pain, edema, acid reflux, mind “fog,” or dandruff—life is good without wheat!

While the gravy is also dairy-free for those with dairy intolerances, the biscuits are not, as there are cheese and butter in the biscuits, both of which are optional, e.g., leave out the cheese and replace butter with coconut or other oil.

Makes 10 biscuits

Gravy:
2 tablespoons extra-virgin olive oil
1 pound loose sausage meat
2½ cups beef broth
¼ cup coconut flour
½ cup coconut milk (canned variety)
1 tablespoon onion powder
1 teaspoon garlic powder
½ teaspoon sea salt
Dash ground black pepper

Biscuits:
1 cup shredded cheddar (or other) cheese
2 cups almond meal/flour
¼ cup coconut flour
¾ teaspoon baking soda
½ teaspoon sea salt
2 large eggs
4 ounces butter, melted (or other oil, e.g., extra-light olive, coconut, walnut)

To make gravy:
In large skillet, heat oil over medium heat. Sauté sausage, breaking up as it browns. Cook until thoroughly cooked and no longer pink.

Turn heat up to medium to high and pour in beef broth. Heat just short of boiling, then turn down to low heat. Stir in coconut flour, little by little, over 3-5 minutes; stop adding when gravy obtains desired thickness. Pour in coconut milk and stir in well.

The Perfect Carnivore

2. Otubru 2012 William Davis (19)

People who carry the gene for lipoprotein(a), Lp(a), tend to be:

--Intelligent--The bell curve of IQ is shifted rightward by a substantial margin.
--Athletic--With unusual capacity for long-endurance effort, thus the many marathoners, triathletes, and long-distance bikers with Lp(a).
--Tolerant to dehydration
--Tolerant to starvation
--Resistant to tropical infections

In other words, people with Lp(a) have an evolutionary survival advantage. More than other people, they make clever, capable hunters who can run for hours to chase down prey, not requiring food or water, and less likely to succumb to the infections of the wild. In a primitive setting, people with Lp(a) are survivors. Evolution has likely served to select Lp(a) people for their superior survival characteristics.

But wait a minute: Isn't Lp(a) a risk for heart attack and stroke? Don't we call Lp(a) "the most aggressive known cause for heart disease and stroke that nobody gives a damn about"?

Yes. So what allows this evolutionary advantage for survival to become a survival disadvantage?

Carbohydrates, especially those from grains and sugars. Let me explain.

More so than other people, Lp(a) people express the small LDL pattern readily when they consume carbohydrates such as those from "healthy whole grains." Recall that the gene for Lp(a) is really the gene for apoprotein(a), the protein that, once produced by the liver and released into the bloodstream, binds to an available LDL particle to create the combination Lp(a) molecule. If the LDL particle component of Lp(a) is small, it confers greater atherogenicity (greater plaque-causing potential). Thus, carbohydrate consumption makes Lp(a) a more aggressive cause for atherosclerotic plaque. The situation can be made worse by exposure to vegetable oils, such as those from sunflower or corn, which increases production of apo(a).

Also, more than other people, Lp(a) people tend to show diabetic tendencies with consumption of carbohydrates. Eat "healthy whole grains," for instance, or if a marathoner carb-loads, he/she will show diabetic-range blood sugars. I have seen long-distance runners or triathletes, for instance, have a 6 ounce container of sugary yogurt and have blood sugars of 200 mg/dl or higher. The extreme exercise provides no protection from the diabetic potential.

Because carbohydrates are so destructive to the Lp(a) type, it means that people with this pattern do best by 1) absolutely minimizing exposure to carbohydrates and vegetable oils, ideally grain-free and sugar-free, and 2) rely on a diet rich in fats and proteins.

The perfect diet for the Lp(a) type? It would be a diet of feasting on the spoils of the hunt, devouring the wild boar captured and slaughtered and eating the snout, hindquarters, spleen, kidneys, heart, and bone marrow, then eating mushrooms, leaves, nuts, coconut, berries, small rodents, reptiles, fish, birds, and insects when the hunt is unproductive.

Capable hunter, survivor, consumer of muscle and organ meats: I call people with Lp(a) "The Perfect Carnivores."

Track Your Plaque in the news

19. Setenbru 2012 William Davis (6)

The NPR Health Blog contacted me, as they were interested in learning more about health strategies and tools that are being used by individuals without their doctors. The Track Your Plaque website and program came up in their quest, as it is the only program available for self-empowerment in heart disease.

Several Track Your Plaque Members spoke up to add their insights. The full text of the article can be viewed here.

How's Your Cholesterol? The Crowd Wants To Know
Mainstream medicine isn't in favor of self-analysis, or seeking advice from non-professionals, of course. And anyone who does so is running a risk.

But there are folks who want to change the course of their heart health with a combination of professional and peer support. Some are bent on tackling the plaque that forms in arteries that can lead to heart disease. They gather online at Track Your Plaque, or "TYP" to the initiates.

"We test, test, test ... and basically experiment on ourselves and have through trial and error came up with the TYP program, which is tailored to the individual," Patrick Theut, a veteran of the site who tells Shots he has watched his plaque slow, stop and regress.

The site was created in 2004 by Bill Davis, a preventive cardiologist in Milwaukee, Wisc. Davis is also the author of Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health, which argues that wheat is addictive and bad for most people's health. Davis recommends eliminating wheat from the diet to most new members of Track Your Plaque.

"The heart is one of the hardest things to self-manage but when you let people take the reins of control, you get far better results and far fewer catastrophes like heart attacks," Davis tells Shots.

Doctors typically give patients diagnosed with heart disease two options: take cholesterol-lowering statin drugs, or make lifestyle changes, like diet. It's usually far easier for both parties — the doctor and the patient — to go with the drugs than manage the much more difficult lifestyle changes, Davis says.

"Doctors say take the Lipitor, cut the fat and call me if you have chest pain," he explains. "But that's an awful way to manage care."

TYP has members submit their scores from heart CT scans, cholesterol values, lipoproteins and other heart health factors to a panel of doctors, nutritionists and exercise specialists. Then they receive advice in the form of an individualized plaque-control program. But the online forum, where users share their results with other members and exchange tips, is where most of the TYP action happens.

The community currently has about 2,400 members who pay $39.95 for a quarterly membership, or $89.75 for a yearly membership. Davis says all proceeds go towards maintaining the website.

Ilaine Upton is a 60-year-old bankruptcy lawyer from Fairfax, Va., and a TYP member. At a friend's suggestion, Upton decided to get a heart CT scan in July. Her score was higher than it should have been (22 instead of 0), so she decided to get her blood lipids and cholesterol tested, too, and sent a sample off to MyMedLabs.com.

She learned that her LDL particle count was over 2,000 ("crazy high," she says), and she posted her results on TYP. Davis advised her that a low-carb diet would reduce it, so she decided to try it.

Since July, she says she has had "excellent results" with the program, and her LDL counts are coming down.

"It would be nice to have a [personal] physician involved in this, but [my insurer] Blue Cross won't pay if you are not symptomatic, and I am trying to prevent becoming symptomatic," says Upton. "I feel very empowered by this knowledge and the ability to take better control of my health by getting feedback on the decisions I make."

Pecan Streusel Coffee Cake

5. Setenbru 2012 William Davis (1)

This is about as decadent as it gets around here!

Here’s a recreation of an old-fashioned coffee cake, a version with a delicious chewy-crunchy streusel topping.

I’ve specified xylitol as the sweetener in the topping, as it is the most compatible sweetener for the streusel “crumb” effect and browning.

Variations are easy. For example, for an apple pecan coffee cake, add a layer of finely-chopped or sliced apples to the cake batter and topping.

Additional potential carbohydrate exposure comes from the garbanzo bean flour and molasses. However, distributed into 10 slices, each slice provides 7.2 grams “net” carbs (total carbs minus fiber), a perfectly tolerable amount. Be careful not to exceed two slices!

Yield 10 slices

Cake:
2½ cups almond flour
½ cup garbanzo bean flour
1 tablespoon ground cinnamon
1 teaspoon baking soda
Sweetener equivalent to ¾ cup sugar
Dash sea salt

3 eggs separated
3/8 teaspoon cream of tartar
1 tablespoon vanilla extract
4 ounces butter, melted
Juice of ½ lemon

Topping:
½ cup almond flour
¼ cup pecans, finely chopped
1 tablespoon ground cinnamon
½ cup xylitol
1 tablespoon molasses
6 ounces butter, cut into ½-inch widths, at room temperature

Preheat oven to 325º F. Grease bread pan.

In bowl, combine almond flour, garbanzo flour, cinnamon, baking soda, sweetener, salt, and mix.

In small bowl, whip egg whites and cream of tartar until stiff peaks form. At low speed, blend in egg yolks, vanilla, melted butter, and lemon juice.

Pour liquid mixture into almond mixture and mix thoroughly. Pour into microwave-safe bread pan and microwave on high for 3 minutes. Remove and set aside.

To make topping, combine almond flour, pecans, cinnamon, xylitol, and molasses in small bowl and mix. Mix in butter

Spread topping on cake. Bake for 20 minutes or until toothpick withdraws dry.

Recipe: Peanut Butter and Jelly Macaroons

16. Agostu 2012 William Davis (3)

If you miss peanut butter and jelly sandwiches, you’re going to absolutely love these peanut butter and jelly macaroons!

Not everybody loves the taste or texture of coconut. This issue is solved by the first step: toasting shredded coconut, then reducing them down to a granular consistency. This yields a macaroon consistency without the dominant coconut taste, replaced instead with the flavors of PB & J.

I’ve specified liquid stevia as the sweetener, but this is easily replaced by your choice of sweetener. Note that, regardless of which sweetener used, they vary in sweetness from brand to brand and the quantity required to equal the ½ cup of sugar equivalent can vary. It always helps to taste your batter and adjust sweetness.

Also, I used Swerve in this recipe, the erythritol-inulin mix that enhances texture, but its use is optional.

As written, each macaroon contains just over 3 grams “net” carbohydrates (total carbs minus fiber), meaning you can have several before doing any damage!

Makes 24 macaroons

3 cups shredded unsweetened coconut
2 tablespoons vanilla extract
1 teaspoon almond extract
¼ cup coconut flour
¼ cup dried unsweetened cherries (or other unsweetened berries)
2 tablespoons coconut oil
¼ cup natural peanut butter, room temperature
2 egg whites
½ teaspoon liquid stevia or sweetener equivalent to ½ cup sugar
2 tablespoons Swerve

Preheat oven to 300° F.

In large bowl, combine coconut, vanilla and almond extracts, and mix.

Spread mixture on baking sheet and bake for 10 minutes, stirring occasionally, until very lightly browned. Be careful not to burn. Remove and cool. (Leave oven at 300° F.)

When cooled, using food chopper, food processor, or coffee grinder, pulse coconut mixture until coconut reduced to consistency of coffee grounds. Pour back into bowl. Stir in coconut flour.

Place cherries or other berries in food chopper, food processor, or coffee grinder and pulse until reduced to small granules or paste. Remove with spatula and add to coconut mixture. Set aside.

Place egg whites in bowl and whip until frothy and stiff peaks form.

In small microwave-safe bowl, combine coconut oil and peanut butter and microwave in 10-second increments until warm (not hot) liquid. Stir in egg whites, followed by stevia and Swerve, and blend thoroughly.

Dispense dough onto a parchment paper-lined baking sheet using a 1 ½-inch cookie scooper or spoons.

Bake for 15 minutes or until lightly browned.

I Wish I Had Lipoprotein(a)!

8. Agostu 2012 William Davis (33)

Why would I say such a thing? Well, a number of reasons. People with lipoprotein(a), or Lp(a), are, with only occasional exceptions:

--Very intelligent. I know many people with this genetic pattern with IQs of 130, 140, even 160+.
--Good at math--This is true more for the male expression of the pattern, only occasionally female. It means that men with Lp(a) gravitate towards careers in math, accounting, financial analysis, physics, and engineering.
--Athletic--Many are marathon runners, triathletes, long-distance bicyclists, and other endurance athletes. I tell my patients that, if they want to meet other people with Lp(a), go to a triathlon.
--Poor at hydrating. People with Lp(a) have a defective thirst mechanism and often go for many hours without drinking water. This is why many Lp(a) people experience the pain of kidney stones: Prolonged and repeated dehydration causes crystals to form in the kidneys, leading to stone formation over time.
--Tolerant to dehydration--Related to the previous item, people with Lp(a) can go for extended periods without even thinking about water.
--Tolerant to periods of food deprivation or starvation--More so than other people, those with Lp(a) are uncommonly tolerant to days without food, as would occur in a wild setting.

In short, people with Lp(a) are intelligent, athletic, with many other favorable characteristics that provide a survival advantage . . . in a primitive world.

So when did Lp(a) become a problem? When an individual with Lp(a) is exposed to carbohydrates, especially those from grains. When an evolutionarily-advantaged Lp(a) individual is exposed to carbohydrates, more than other people they develop:

--Excess quantities of small LDL particles--Recall that Lp(a) is a two-part molecule. One part: an apo(a) made by the liver. 2nd part: an LDL particle. When the LDL particle within the Lp(a) molecule is small, its overall behavior is worse or more atherogenic (plaque-causing).
--Hyperglycemia/hyperinsulinemia--which then leads to diabetes. Unlike non-Lp(a) people, these phenomena can develop with far less visceral fat. A Lp(a) male, for instance, standing 5 ft 10 inches tall and weighing 150 pounds, can have as much insulin resistance/hyperglycemia as a non-Lp(a) male of similar height weighing 50+ pounds more.

Key to gaining control over Lp(a) is strict carbohydrate limitation. Another way to look at this is to say that Lp(a) people do best with unlimited fat and protein intake.

Thyroid: Be a perfectionist

27. Julhu 2009 William Davis (18)

If you'd like to reduce LDL cholesterol with nearly as much power as a statin drug, think thyroid.

When thyroid is corrected to ideal levels, LDL cholesterol drops 20, 30, 40 mg/dl or more, depending on how poor thyroid function and how high LDL are at the start. The poorer the thyroid function (the higher the TSH or the lower the T3 and T4) and the higher the LDL cholesterol, the more LDL drops with thyroid correction.

(For those of you minding LDL particle size, such as Track Your Plaque Members, the "dominant" LDL species will drop: If you are genetic small LDL, small LDL will drop. If you have mostly large LDL because of being wheat-free and sugar-free, then large LDL will drop.)

One of the problems is that many healthcare providers blindly follow what the laboratory says is "normal" or the "reference range," which is usually nothing more than a population average (actually the mean +/- 2 standard deviations, a common method of developing references ranges). In other words, a substantial degree of low thyroid function, or hypothyroidism, can be present when your doctor adheres to the reference range provided by the laboratory.

What does it mean to achieve ideal thyroid status? My list includes:

--Normal oral temperature of 97.3 F first upon arising. (The thyroid is the body's thermoregulatory organ.)
--TSH 1.0 mIU/L or less
--Free T3 upper half "normal" range
--Free T4 upper half "normal" range
--You feel good: mental clarity, energy, upbeat mood. You lose weight when you try.

Iodine replacement should be part of any thyroid health effort. Iodine is not an optional trace mineral, no more than vitamin C is optional (else your teeth fall out). The only dangers to iodine replacement are to those who have been starved of iodine for many years; increase iodine and the thyroid can over-respond. I've seen this happen in 2 of the last 300 people who have supplemented iodine.

In my view, neglecting T3 replacement is absurd. While it is not clear to me why many otherwise healthy people have low T3 at the low range of "normal" or even in the below-normal range, people feel better and have better health--faster weight loss, reduced LDL, reduced triglycerides, they are happier and enjoy more energy--when T3 is increased to the upper half of the reference range. (Crucial question: Why is the 5'-deiodinase enzyme that converts T4 to T3 inhibited, resulting in reduced free T3? What is in our diets or environment that is exerting this effect? I don't have answer, but we sorely need one.)

It pays to be a perfectionist when it comes to thyroid. Not only do you feel better, but LDL cholesterol can drop with a statin-like magnitude, but with none of the adverse effects.

If interested, Track Your Plaque offers fingerstick blood spot testing that you can perform in your own home. Each test kit will test for: TSH, free T3, free T4, along with a thyroid peroxidase antibody (a marker for Hashimoto's thyroiditis, an autoimmune inflammatory condition of the thyroid).

Nutrition Syllogism

21. Julhu 2009 William Davis (21)

What do you think of these chains of logic?

Cyanide is a potent lethal poison; carbon monoxide is a less lethal poison.
Therefore: plenty of carbon monoxide is good.

Having uterine cancer is a bad thing. Having uterine fibroids is a less bad thing.
Therefore: plenty of uterine fibroids are good.

These are obvious examples of seriously flawed logic. Students of logic and philosophy will recognize the above erroneous sequences as examples of the twisted arguments often used to persuade an argumentative opponent of the logic of a premise. As long ago as 335 B.C., Greek philosopher, Aristotle, recognized the pitfalls of thinking in such arguments. You think we’d know better by now.

Try this one:

White enriched flour is a bad for health; whole grains are less bad for health.
Therefore: plenty of whole grains are good for health.

Ouch!

In the 1960s, we all ate hot dogs on white buns, white flour Wonder Bread® sandwiches, Mom made cookies and cupcakes with white flour. Then, during the 1970s and 1980s, clinical studies were performed demonstrating that whole wheat and whole grains reduced colon cancer, high blood pressure, diabetes, and heart disease compared to white flour. In other words, add back fiber and B vitamins and health benefits develop: No argument here.

Therefore: whole grains must be good for health. Further, lots of whole grains?unlimited quantities of whole grains many times per day, every day?must be even better. Even the USDA says so on their nutrition pyramid, with 8-11 servings of grains per day, 4 of which should be whole grains, at the widest portion of the pyramid.

But what happens when you follow this logic through and fill your diet with whole grains?

Look around you and it’s easy to see: Appetite increases, people become obese, blood sugar increases, diabetes develops, HDL cholesterol plummets, triglycerides skyrocket, inflammatory patterns (e.g., c-reactive protein, or CRP) increase, small LDL (the number one cause for heart disease in the obese U.S.!) shoots through the roof.

I would no more fill my diet with “healthy whole grains” than I would close my garage door with the car running.

Is pomegranate juice healthy?

19. Julhu 2009 William Davis (20)

Pomegranate juice, 8 oz:

Sugars, total 31.50 g

Sucrose 0.00 g

Glucose (dextrose) 15.64 g

Fructose 15.86 g

In your quest to increase the flavonoids in your diet, do you overexpose yourself to fructose?

Remember: Fructose increases LDL cholesterol, apoprotein B, small LDL, triglycerides, and substantially increases deposition of visceral fat (fructose belly?). How about a slice of whole grain bread with that glass of pomegranate juice? The Heart Association says it's all low-fat!

(Coming on the Track Your Plaque website: A full in-depth Special Report on fructose in all its glorious forms and whether this is truly an issue for your health. Fructose tables and the scientific data to establish a safe "threshold" value will be included.)

Honeydew melon

18. Julhu 2009 William Davis (4)

Honeydew melon:

Sugars, total 51.97 g

Sucrose 15.87 g

Glucose 17.15 g

Fructose 18.94 g

Because sucrose is half fructose (the other half is glucose), there are approximately 26 grams of fructose per one-half honeydew melon.

Apple, 1 medium: Fructose 10.74 g

Honey: Fructose 17.19 grams per 2 tablespoons

Barbecue Sauce: HFCS number 1 ingredient

Do heart scans cause cancer?

14. Julhu 2009 William Davis (3)

Another in a series of data extrapolations that attempt to predict long-term cancer risk from medical radiation exposure was published in the July 13, 2009 Archives of Internal Medicine, viewable here.

Over the years, I've fussed about the radiation dose used by some centers for CT heart scans. (Note: I'm talking about CT heart scans, not CT coronary angiograms, an entirely different test with different radiation exposure.) In the "old" days, when electron-beam devices (EBT) were the best on the block, the old single-slice CT scanners (the predecessor of the current 64-slice MDCT scanners) exposed patients to ungodly quantities of radiation, while the EBT devices required very small quantities (0.5 mSv or about the equivalent of 4 standard chest x-rays or one mammogram).

But CT technology has advanced considerably. While EBT has been phased out (although it was an exceptional technology, GE acquired the small California manufacturer, then promptly scrapped the operation; you can guess why), multi-detector CT (MDCT) technology has improved in speed, image quality, and radiation exposure.

While it has improved, radiation exposure still remains an issue. The authors of the study applied the scanning protocols used at three hospitals and those in several CT heart scan studies, then calculated radiation exposure. They found a more than ten-fold range of exposure, from 0.8 mSv to 10.5 mSv. (All scanners were MDCT, none EBT.)

That's precisely what I've been worrying about: In the rapid rush to develop new devices, radiation exposure has often been a neglected issue. While some scan centers do an excellent job and take steps to minimize exposure, others barely lift a finger and consequently expose their patients to unnecessary radiation.

However, it's not as bad as it sounds. For one, the study included 16-slice MDCT scanners, a scanner type that I warned people to not use because of radiation. On the current most popular 64-slice devices, much lower radiation exposure is possible, on the order of 0.8-1.2 mSv routinely--if the center takes the effort.

This study, while eye-opening, will achieve some good: CT heart scans are here to stay. But the day-to-day practice of heart scanning should be:

1) standardized
2) conducted with radiation exposure as low as possible, preferably <0.8 mSv

To read more about this issue, below I've reprinted a 2007 full Track Your Plaque Special Report, CT Heart Scans and Radiation: The Real Story.

CT heart scans and radiation: The real story

“My personal opinion is that many patients today who are receiving multiple CT scans may well be getting at least comparable doses to subjects that have now developed malignancies from x-ray radiation received in the 1930s and '40s. And, similar to those days when the doses were unknown, the dose that patients receive today over a course of years of multiple CT scans is also completely unknown . . .

“I recommend that all healthcare providers become familiar with the concept that 1 in 1000 CT studies of the chest, abdomen, or pelvis may result in cancer.”

Richard C. Semelka, MD

Professor and Vice Chairman, Department of Radiology

University of North Carolina–Chapel Hill

Is this just hype to generate headlines? Or is the truth buried in the enormous marketing clout of the medical device industry, among which the imaging device manufacturers reign supreme?

It’s been over 110 years since radiation was first used for medical imaging. Over those years, it has had its share of misadventures.

In the 1930s and 1940s, before the dangers of radiation were recognized, shoe shoppers had shoes fitted using an x-ray device of the foot to assess fit. High doses of radiation were used to shrink enlarged tonsils and extinguish overactive thyroid glands. Attitudes towards radiation were so lax that doctors commonly permitted themselves to be exposed without protection day after day, year after year, until an unexpected rise in blood cancers like leukemia was observed. As recently as the 1970s and 1980s, cancers like Hodgkins’ disease were treated with high doses of radiation, also leading to radiation-induced diseases decades later.

Not all radiation is bad. Radiation can also be used as a therapeutic tool and even today remains a useful and reasonably effective method to reduce the size, sometimes eliminate, certain types of cancer. Forty percent of people with cancer now receive some form of radiation as part of their treatment (Ron E 2003).

Just how much does medical radiation add to our exposure?

Estimates vary, but most experts estimate that medical imaging provides approximately 15% of total lifetime exposure. In other words, radiation exposure from medical imaging is simply a small portion of total exposure that develops over the years of life. Exposure can be much higher, however, in a specific individual who undergoes repeated radiation imaging or treatment of one sort or another.

For all of us, exposure to medical radiation is part of lifetime exposure from multiple sources, added to the radiation we receive from the world around us. Just by living on earth, we are exposed to radiation from space and naturally-occurring radioactive compounds, and receive somewhere around 3.0 mSv per year (U.S. Nuclear Regulatory Commission). (Doses for radiation exposure are commonly expressed in milliSieverts, mSv, a measure that reflects whole-body radiation exposure.) People living in high-altitude locales like Colorado get exposed to an additional 30–50% ambient radiation (1.0–1.5 mSv more per year).

Much of the information on radiation exposure comes from studies like the Life Span Study that, since 1961, has tracked 120,000 Japanese exposed to radiation from the atomic bombs dropped in 1945 (Preston DL et al 2003). Although regarded as a high-dose exposure study for obvious reasons, there are actually thousands of people in this study who were exposed to lesser quantities of radiation (because of distance from the bomb sites) who still display a “dose-response” increased risk for cancer many years later in life. Radiation exposures of as little as 5–20 mSv showed a slight increase in lifetime risk.

Occupational and excessive medical exposure to radiation also provides a “laboratory” to examine radiation risk. Miners exposed to radon gas; patients exposed to the imaging agent, Thorotrast, containing radioactive isotope thorium dioxide and used as an x-ray contrast agent in the 1930s and 1940s and possesses the curious property of lingering in the body for over 30 years after administration; radium injections administered between 1945 and 1955 to treat diseases like ankylosing spondylitis and tuberculosis, all provide researchers an opportunity to study the long-term effects of various types of radiation exposure over many years (Harrison JD et al 2003).

The excess exposure of workers and several hundred thousand nearby residents to the Mayak nuclear plant in Russia has also revealed a “dose-response” relationship, with increasing exposure leading to more cancers, including leukemia and solid cancers of the bone, liver, and lung (Shilnikova NS et al 2003). Nuclear waste released into the Techa river between 1948 and 1956 contaminated drinking water used by over 100,000 Russians. A plant explosion in 1957 also released an excess of radiation into the atmosphere, yielding exposure via inhalation. Some sources estimate that at least 272,000 people have been affected by radiation from the Mayak plant. This unfortunate situation has, however, yielded plenty of data on radiation exposure and its long-term effects.

It’s also been known for several decades that people who receive therapeutic radiation for treatment of cancer, even with the reduced doses now employed, are subject to increased risk of a second cancer consequent to the radiation treatment.

From experiences like this, radiation experts estimate that an exposure of 10 mSv increases a population’s risk for cancer by 1 in 1000 (Semelka RC et al 2007).

This question was recently thrust into the spotlight with publication of a study from Columbia University in New York suggesting that a 20-year old woman would be exposed to a lifetime risk of cancer as high as 1 in 143 consequent to the radiation received during a CT coronary angiogram. (Important note: This was estimated risk from a CT coronary angiogram, not a simple heart scan that we advocate for the Track Your Plaque program.) The risk at the low end of the spectrum would be in an 80-year old man (because of the shorter period of time to develop cancer), with a risk of 1 in 5017. If “gating” to the EKG is added (which many scan centers do indeed perform nowadays), risk for a 60-year old woman is estimated at 1 in 715; risk for a 60-year old male, 1 in 1911 (Einstein AJ et al 2007). This study generated some criticism, since it did not directly involve human subjects, but used “phantoms” or x-ray dummies to simulate x-ray exposure. Nonetheless, the point was made: CT coronary angiograms in current practice do indeed expose the patient to substantial quantities of radiation, sufficient to pose a lifetime risk of cancer.

The media frenzy

The NY Times ran an article called With Rise in Radiation Exposure, Experts Urge Caution on Tests in which they stated:

"According to a new study, the per-capita dose of ionizing radiation from clinical imaging exams in the United States increased almost 600 percent from 1980 to 2006. In the past, natural background radiation was the leading source of human exposure; that has been displaced by diagnostic imaging procedures, the authors said."

“This is an absolutely sentinel event, a wake-up call,” said Dr. Fred A. Mettler Jr., principal investigator for the study, by the National Council on Radiation Protection. “Medical exposure now dwarfs that of all other sources.”

Radiation is a widely used imaging tool in medicine. Although CT scans of the brain, bones, chest, abdomen, and pelvis account for only 5% of all medical radiation procedures, they are responsible for nearly 50% of medical radiation used. It’s been known for years that increasing radiation exposure increases cancer risk over many years, but the boom of newer, faster devices that provide more detailed images has opened the floodgates to expanded use of CT scanners.

But before we join in the hysteria, let's first take a look at exposure measured for different sorts of tests:

Typical effective radiation dose values for common tests

Computed Tomography

Head CT 1 – 2 mSv
Pelvis CT 3 – 4 mSv
Chest CT 5 – 7 mSv
Abdomen CT 5 – 7 mSv
Abdomen/pelvis CT 8 – 11 mSv
Coronary CT angiography 5 – 12 mSv

Non-CT

Hand radiograph Less than 0.1 mSv
Chest radiograph Less than 0.1 mSv
Mammogram 0.3 – 0.6 mSv
Barium enema exam 3 – 6 mSv
Coronary angiogram 5 – 10 mSv
Sestamibi myocardial perfusion (per injection) 6 – 9 mSv
Thallium myocardial perfusion (per injection) 26 – 35 mSv

Source: Cynthia H. McCullough, Ph.D., Mayo Clinic, Rochester, MN

A plain, everyday chest x-ray, providing less than 0.1 mSv exposure, provides about the same quantity of radiation exposure as flying in an airplane for four hours, or the same amount of radiation from exposure to our surroundings for 11–12 days. Similar exposure arises from dental x-rays.

If you have a heart scan on an EBT device, then your exposure is 0.5-0.6 mSv, roughly the same as a mammogram or several standard chest x-rays.

With a heart scan on a 16- or 64-slice multidetector device, exposure is ideally around 1.0-2.0 mSv, about the same as 2-3 mammograms, though dose can vary with this technology depending on how it is performed (gated to the EKG, device settings, etc.)

CT coronary angiography presents a different story. This is where radiation really escalates and puts the radiation exposure issue in the spotlight. As Dr. Cynthia McCullough's chart shows above, the radiation exposure with CT coronary angiograms is 5-12 mSv, the equivalent of 100 or more chest x-rays or 20 mammograms. Now, that's a problem.

The exposure is about the same for a pelvic or abdominal CT. The problem is that some centers are using CT coronary angiograms as screening procedures and even advocating their use annually. This is where the alarm needs to be sounded. These tests, as wonderful as the information and image quality can be, are not screening tests. Just like a pelvic CT, they are diagnostic tests done for legitimate medical questions. They are not screening tests to be applied broadly and used year after year.

It’s also worth giving second thought to any full body scan you might be considering. These screening studies include scans of the chest, abdomen, and pelvis. These scans, performed for screening, expose the recipient to approximately 10 mSv of radiation (Radiological Society of North American, 2007). Debate continues on whether the radiation exposure is justified, given the generally asymptomatic people who generally undergo these tests.

Always be mindful of your radiation exposure, as the NY Times article rightly advises. However, don't be so frightened that you are kept from obtaining truly useful information from, for instance, a CT heart scan (not angiography) at a modest radiation cost.

Heart scans, CT coronary angiograms and the future

Unfortunately, practicing physicians and those involved in providing CT scans are generally unconcerned with radiation exposure. The majority, in fact, are entirely unaware of the dose of radiation required for most CT scan studies and unaware of the cancer risk involved. It is therefore up to the individual to insist on a discussion of the type of scanner being used, the radiation dose delivered (at least in general terms), the necessity of the test, alternative methods to obtain the same diagnostic information, all in the context of lifetime radiation exposure.

Our concerns about radiation exposure all boil down to concern over lifetime risk for cancer, a disease that strikes approximately 20% of all Americans. Many factors contribute to cancer risk, including obesity, excessive saturated fat intake, low fiber intake, lack of vitamin D, repeated sunburns, excessive alcohol use, smoking, exposure to pesticides and other organochemicals, asbestos and other industrial exposures, electromagnetic wave exposure, and genetics. Radiation is just one source of risk, though to some degree a controllable one.

Some people, on hearing this somewhat disturbing discussion, refuse to ever have another medical test requiring radiation. That’s the wrong attitude. It makes no more sense than wearing lead shielding on your body 24 hours a day to reduce exposure from the atmosphere. Taken in the larger context of life, radiation exposure is just one item on a list of potentially harmful factors.

It is, however, worth some effort to minimize radiation exposure over your lifetime, particularly before age 60, and by submitting to high-dose testing only when truly necessary, or when the potential benefits outweigh the risks. Thus, with heart scans and CT coronary angiography, some thought to the potential benefits of knowing your score or the information gained from the CT angiogram need to be considered before undergoing the test. Often the practical difficulty, of course, is that your risk for heart disease simply cannot be known until after the test.

In our view, in the vast majority of instances a simple CT heart scan can serve the simple but crucial role of quantifying risk for heart attack and atherosclerotic plaque. CT heart scans yield this information with less than a tenth of the radiation exposure of a CT coronary angiogram. In people without symptoms and a normal stress test, there is rarely a need for CT coronary angiography with present day levels of radiation exposure. Perhaps as technology advances and the radiation required to generate images is reduced, then we should reconsider.

Early experiences are suggesting that the newest 256-slice scanners, now being developed but not yet available, will cut the dose exposure of 64-slice CT angiograms in half (from 27.8 mSv to 14.1 mSv in a recent Japanese study). The 256-slice scanners will allow scanning that is faster over a larger area in a given period of time.

Thankfully, the scanner manufacturers are increasingly sensitive to the radiation issue and have been working on methods to reduce radiation exposure. However, it still remains substantial.

Goodbye, fructose

12. Julhu 2009 William Davis (35)

A carefully-conducted study by a collaborative research group at University of California-Berkeley has finally closed the lid on the fuss over fructose vs. glucose and its purported adverse effects.

The study is published in its entirety here.

Compared to glucose, fructose induced:

1) Four-fold greater intra-abdominal fat accumulation--3% increased intra-abdominal fat with glucose; 14.4% with fructose. (Intraabdominal fat is the variety that blocks insulin responses and causes diabetes and inflammation.)

2) 13.9% increase in LDL cholesterol but double the increase for Apoprotein B (an index of the number of LDL particles, similar to NMR LDL particle number).

3) 44.9% increase in small LDL, compared to 13.3% with glucose.

4) While glucose (curiously) reduced the net postprandial (after-eating) triglyceride response (area under the curve, AUC), fructose increased postprandial triglycerides 99.2%.

The authors propose that fructose specifically increases liver VLDL production, the lipoprotein particle that yields abnormal after-eating particles, increased LDL, and provides building blocks to manufacture small LDL particles. The authors also persuasively propose that fructose metabolism, unlike glucose, is not inhibited (via feedback loop) by energy intake, i.e., it's as if you are always starving.

Add to this the data that show that fructose increases uric acid (that causes gout and may act as a coronary risk factor), induces leptin resistance, causes metabolic syndrome (pre-diabetes), and increases appetite, and it is clear that fructose is yet another common food additive that, along with wheat, is likely a big part of the reason Americans are fat and diabetic.

Fructose is concentrated, of course, in high-fructose corn syrup, comprising anywhere from 42-90% of total weight. Fructose also composes 50% of sucrose (table sugar). Fructose also figures prominently in many fruits; among the worst culprits are raisins (30% fructose) and honey (41% fructose).

Also, beware of low-fat or non-fat salad dressings (rich with high-fructose corn syrup), ketchup, beer, fruit drinks, fruit juices, all of which are rich sources of this exceptionally fattening, metabolism-bypassing, LDL cholesterol/small LDL/ApoB increasing compound. Ironically, this means that many low-fat foods meant to reduce cholesterol actually increase it when they contain fructose in any form.

When you hear or say "fructose," run the other way, regardless of what the Corn Refiners Association says.

The statin-free life

8. Julhu 2009 William Davis (20)

Matt came to me because his doctor couldn't reduce his LDL cholesterol.

His doctor had prescribed Zocor (simvastatin), Lipitor, Crestor, even pravastatin, all of which resulted in incapacitating muscle aches and weakness within a week of starting. No surprise, Matt had a jaundiced view of statin drugs.

We started out by characterizing his lipoprotein patterns:

--LDL 155 mg/dl

--72% of LDL was small LDL, a moderately severe pattern. (This means that small LDL comprised 112 mg/dl of the total 155 mg/dl LDL; large LDL comprised 43 mg/dl--small LDL was the problem.)

--HDL 42 mg/dl --Triglycerides 133 mg/dl

--No lipoprotein(a)

Beyond lipoproteins, Matt proved severely deficient in vitamin D with a starting level of 18 ng/ml.

Matt's doctor had advised that he avoid salt, as his blood pressure had been borderline high. His thyroid assessment disclosed a TSH of 3.89 mIU/ml with thyroid hormones free T3 and free T4 in the lower half of the normal range.

I therefore asked Matt to:

--Eliminate wheat, cornstarch, and sugars to reduce small LDL
--Add iodine
--Supplement 6000 units of an oil-based vitamin D preparation
--Take fish oil to provide at least 1800 mg EPA + DHA per day
--Take Armour Thyroid 1 grain per day

Several months later on this program, Matt had a repeat basic lipid panel:

--LDL 82 mg/dl--a 47% reduction

--HDL 52 mg/dl a 24% increase

--Triglycerides 60 mg/dl--a 55% decrease

In addition, vitamin D was 66 ng/ml, TSH was <1.0 mIU/ml with free T3 and free T4 in the upper half of the "reference range." Matt also felt great.

While the numbers could be slightly better, Matt had made tremendous progress towards achieving perfect values.

There you have it: Marked correction of cholesterol values, no statin drugs involved.

Creatine: Not just for muscle heads

5. Julhu 2009 William Davis (29)

Even if you’re not interested in building big muscles like a bodybuilder, there are health benefits to increasing muscle mass: increased bone density, better balance, and fewer injuries. Greater muscle mass means higher metabolic rate, improved insulin responsiveness, lower blood sugar. The inevitable loss of muscle mass of aging can lead to frailty, an increasingly common situation for the elderly. Muscle loss be reversed, health improved as a result.

Since its introduction in 1994, creatine has exploded in popularity, particularly among bodybuilders and athletes interested in gaining muscle mass and strength. But creatine is not just for young weight lifters. If you are just interested in increasing muscle mass for its health benefits, then creatine is something to consider.

A study of creatine supplementation in men, average age 70 years, demonstrated that, when creatine was combined with strength training, it increased muscle mass 250% better than placebo (7.26 lb muscle vs 2.86 lb muscle), along with improved leg strength and endurance. The same group also demonstrated 3.2% increased bone density (measured using dual energy X-ray absorptiometry) after 12 weeks in participants taking creatine with strength training, while the control (no strength training, no creatine) group decreased by 1.0%.

Benefits are not confined to men. Similar results were observed in another study that included women (age 65 and older), with outcomes in females comparable to males. This is especially important for females, given the common development of osteopenia and osteoporosis in postmenopausal females.

Other studies have shown that benefits are maintained after stopping creatine supplementation.

The most popular form of creatine is the monohydrate, generally taken as a “loading” phase of 15-20 grams per day (generally split into 3-4 doses of 5 grams) for 5-7 days, followed by weeks to months of 2-5 grams per day.

An alternative form, polyethylene glycosylated creatine (PEG-creatine) provides similar effects at one-fourth to one-half the dose of creatine, i.e., 1.25-2.5 grams per day.

Despite previous concerns about kidney toxicity with prolonged use, another study showed that athletes taking creatine for up to 21 months have shown no adverse effects on kidney function, lipid (cholesterol) values, or other basic health measures.

Having healthy muscle mass doesn't make you bulge like a bodybuilder. With modest efforts at strength training, augmented with creatine supplementation, you have a wonderful tool to feel better, reduce injury, increase bone density, and combat abnormal insulin resistance, not to mention accelerate weight loss, since lean muscle mass consumes energy.

The ultimate “bioidentical” hormone

2. Julhu 2009 William Davis (19)

There has been a lot of debate over whether or not “bio-identical” hormones, i.e., hormones identical to the human form, are superior to non-human forms dispensed by the drug industry.

The FDA is currently taking steps to clamp down on availability of bioidentical hormones and their claims of superiority, despite a groundswell of grassroot support for them. The argument has pitted anti-aging practitioners and the public, as well as the likes of Oprah and Suzanne Somers, against Big Pharma and the FDA, the two forces trying to squash the bioidentical hormone movement.

Regardless of what heavy-handed approach the FDA takes, we already have access to hormones identical to the original human form. It requires no prescription and yields downstream hormones that the human body recognizes as human.

That "bioidentical" hormone is pregnenolone.

Pregnenolone is the first biochemical step in the conversion of dietary cholesterol (yes-cholesterol!) to numerous other hormones. Pregnenolone is the source of the hormones that lie at the center of the bioidentical hormone controversy: estrogens, progesterone, and testosterone. We therefore already have our own over-the-counter, non-prescription form of bioidentical hormones.

Supplemental pregnenolone increases estrogens (mildly), progesterone, and testosterone. Prenenonlone supplementation simply provide more of the basic substrate for hormone production. The increase in hormones is usually modest, not as vigorous as direct hormone replacement like, say, testosterone or progesterone topical creams. But pregnenolone can be useful when small to moderate increases are desired, such as for reduction of Lp(a). A theoretical downside is that pregnenonlone can also convert to cortisol, the adrenal gland hormone that regulates fluid and blood pressure. However, I've not seen any measurable increase in cortisol with low doses of pregnenonlone and limited data suggest that it does not. Pregnenolone also converts to the other adrenal gland hormone, DHEA; I call DHEA "the hormone of assertiveness," since some people who take too much pregnenolone (or direct DHEA) acquire excessive assertiveness.

The key to pregnenolone supplementation is to proceed gradually and begin with a small dose, e.g., 5 mg every morning. Hormonal assessment is best conducted periodically to assess the effects and to determine whether a dose adjustment is in order.

Roger's near-miss CT angiogram experience

27. Junhu 2009 William Davis (13)

Heart Scan Blog reader, Roger, described his near-miss experience with CT coronary angiograms.

Hoping to obtain just a simple CT heart scan, he was bullied to get a CT coronary angiogram instead. Roger held strong and just asked for the test that we all should be having, a CT heart scan.

I posted yesterday that I was about to have my first CT heart scan...well, it was an interesting experience for reasons I coudn't possibly have anticipated. Dr. Davis has commented in the past on the confusion in the media about the difference between a CT calcium score scan, and a CT angiography, the latter requiring a far higher dose of radiation. I assumed this was a source of confusion only among patients and lay folks, but, lo and behold, I discovered today that doctors--or at least their helpers--can be just as confused.

Here's my story:

After checking in, I asked the receptionist to see if she had any information on whether my medical insurance was covering the scan. She called someone, and I heard her say over the phone, "He's here for a CT angiogram." At that point my ears perked up. I explained I wasn't here for a CT angiogram, only a regular CT scan. "Well, do you want to call your doctor and talk about this?" she asked. No, I said, I would like to ask one of their folks to verify exactly what test my doctor had ordered. As luck would have it, the technician was walking by at that point. "Is this a CT angiogram?" the receptionist asked. "No, it's just a CT calcium score scan" was the reply. But apparently the technician had been unclear herself, and had called my doctor just to verify. In other words, the "default" procedure they were accustomed to doing at this august Houston vascular clinic was a CT angiogram.

In fact, my appointment was even listed on their calendar as a "CT angiogram." For all I know, my insurance will be billed for the same. Later, during the procedure, the technician acted surprised I wasn't doing the "full test." I explained I had minimal risk factors (actually only one, an HDL of 34 a couple of years ago, which has since been raised to 50 partly as a result of taking advice from this site), but that my doctor was progressive (he is an MD for the Houston Astros) and thought it was a good idea since there is heart disease in my immediate family. My doctor did indeed prescribe only a CT calcium score scan, but it seems to have been an order that this clinic, at least, wasn't all that used to seeing.

So, I guess the message is: we have a lot of educating to do. Had I not been a faithful reader of these pages, I certainly wouldn't have known what kind of test I was about to get, or what questions to ask!

As for the heart scan itself, a piece of cake. If you can hold your breath, you can take this test. Just be sure it is the right one!

Why the "push" towards CT coronary angiograms and not "just" a CT heart scan? Well, I know it's shocking but it's . . . money!

CT coronary angiograms yield around $1800-$4000 per test. CT heart scans yield somewhere around $200. Though the scan center support staff might not care too much about the money themselves, their administrators likely make the cost distinctions clear to them.

Another reason: Most scan center staff, ironically, don't understand what a heart scan means, nor do they understand how it might serve to launch a program of prevention. They do understand that severe blockage by CT angiogram "needs" to be stented or bypassed. So they push patients towards things they understand.

Nobody makes money from CT heart scans, just as nobody makes money from a mammogram. Heart scans also don't lead to heroic, "lifesaving" procedures. They just lead to this sleepy, unexciting, inexpensive thing called prevention.

The Myth of Prevention: Letter to the Wall Street Journal

25. Junhu 2009 William Davis (20)

The June 20-21, 2009 Wall Street Journal Weekend Journal featured a provocative front page article written by physician, Dr. Abraham Verghese:

The Myth of Prevention

While eloquently written, I took issue with a few crucial points. Here is the letter I sent to the Editor at Wall Street Journal:

Dear Wall Street Journal Editor,

Re: Dr. Abraham Verghese’s article, The Myth of Prevention in the June 20-21, 2009 Weekend Journal.

I believe a more suitable title for Dr. Verghese’s article would be: “The Myth of What Passes as Prevention.”

As a practicing cardiologist, I, too, have witnessed firsthand the systemic “corruption” described by Dr. Verghese, the doing things “to” people rather than “for” them. Heart care, in particular, is rife with this form of profit-driven health delivery.

There is a fundamental flaw in Dr. Verghese’s otherwise admirable analysis: He assumes that what is called “prevention” in mainstream medicine is truly preventive.

Dr. Verghese makes issue of the apparent minor differences between preventing a condition and just allowing a condition to run its course. Prostate cancer screening is one example: Men subjected to repeated screenings have little length-of-life advantage over men who just allow their prostate to suffer the expected course of disease.

What if, instead, “prevention” as practiced today is nothing more than a solution that has been adopted in mainstream practice to suit yet another doing “to” strategy than doing “for”? In the prostate cancer example, PSA and prostate exam screenings often serve as little more than a means of harvesting procedures for the local urologist.

That’s not prevention. It is a prototypical example of “prevention” being subverted into the cause of revenue-generating procedures.

I submit that Dr. Verghese has fallen victim to the very same system he criticizes. His views have unwittingly been corrupted by the corrupt profit-driven system he describes.

What if, instead, prevention were just that: prevention or elimination of the condition. What if “prevention” of prostate cancer eliminated prostate cancer? What if heart disease “prevention” prevented all heart disease? What if this all proceeded without regard for profit or revenue-generating procedures, but just on results?

Dr. Verghese specifically targets heart scans or coronary calcium scoring, a test he likens to “miracle glow-in-the-dark minnow lures,” calling them “moneymakers.” Yes, when subverted into a corrupt algorithm of stress test, heart catheterization, stent, or bypass, heart scans are indeed a test used wrongly to “prevent” heart disease.

But what if the risk insights provided by heart scans prompt the start of a benign yet effective “prevention” program that inexpensively, safely, and assuredly prevents--in the true sense of the word--or eliminates heart disease? Then I believe the differences in mortality, quality of life, and costs would be substantial. Such strategies exist, yet do not necessarily include prescription drugs and certainly do not include the aftermath of heart catheterization and bypass surgery. Yet such programs fail to seize the limelight of media attention with no new high-tech lifesaving headline nor a big marketing budget to broadcast its message.

The problem in medicine is not prevention and its failure to yield cost- and life-saving results. It is the pervasively profit-driven mindset that keeps true preventive strategies from entering mainstream conversation. It is a repeat of Dr. Ignaz Semmelweis’ late 19th-century pleads for physicians to wash their hands before delivering babies to reduce puerperal sepsis, ignominious advice that earned him life and death in an asylum. We are essentially continuing to deliver children with unwashed hands because there is no revenue-generating procedure to clean them.

No, Dr. Verghese, the economic and medical failings of preventive strategies are not at fault. The failure of the medical system, in which everyone is bent on seizing a piece of the financial action for himself, has resulted in the failure to support the propagation of true preventive strategies that could genuinely save money and lives.

President Obama’s goal of cultivating preventive practices in medicine can work, but only if the profit-motive for “prevention” does not serve as the primary determinant of practice. Results-driven practices that are applied without regard to profit have the potential to yield the sorts of cost-saving and life-saving results that can reduce healthcare costs.

A victory for SHAPE, CT heart scans, and doing what is RIGHT

24. Junhu 2009 William Davis (7)

The efforts of Texas House of Representatives Rep. Rene Oliveira and the SHAPE Guidelines committee have paid off: The Texas legislature passed a bill that requires health insurers to cover CT heart scans.

(NOTE: Don't make the same mistake that the media often makes and confuse CT heart scans with CT coronary angiography: two different tests, two different results, two different levels of radiation exposure. The difference is discussed here.)

Track Your Plaque previously reported the release of the SHAPE Guidelines, an ambitious effort to open CT heart scanning to people who would benefit from a simple screening test for coronary disease. Rep. Rene Oliveira initially introduced the bill in 2006, after having a heart scan uncovered extensive coronary plaque that resulted in coronary bypass surgery.

The bill requires that health-benefit providers cover the cost of CT heart scans (and carotid ultrasound) in men between the ages of 45-76, women 55-76, as well as anyone with diabetes or at "intermediate-risk" or higher for coronary disease by Framingham risk score.

The usual panel of cardiology knuckleheads stepped to the media podium, expressing their incredulity that something as "unvalidated" as heart scans could gain the backing of legislative mandate. Heartwire carried this comment:

"Contacted by heartwire, Dr Amit Khera (University of Texas Southwestern Medical Center, Dallas) confirmed there are still no comprehensive, adequately powered studies showing that these screening tests lead to better outcomes. In a phone interview, Khera said he has major concerns about how physicians will use these tests, particularly primary-care physicians. "I gave a talk last week to primary-care doctors, and there were probably 250 people in the room, and when I asked how many people had ordered a calcium scan, just one person raised a hand. . . . Most people don't even know what to do with the Framingham risk score, so they're going to follow an algorithm that they don't know how to follow to order a test result that they don't know what to do with."

It's the same criticisms hurled at heart scans over the years despite literally thousands of studies validating their application.

Studies have conclusively shown that:

--Coronary calcium scores generated by a CT heart scan outperform any other risk measure for coronary disease, including LDL cholesterol, c-reactive protein, total cholesterol, HDL cholesterol, blood pressure.
--Coronary calcium scores yield a graded, trackable index of coronary risk. Scores that increase correlate with increased risk of cardiovascular events; scores that remain unchanged correlate with much reduced risk.
--A coronary calcium score of zero--no detectable calcium--correlates with extremely low 5-year risk for cardiovascular events.
--Coronary calcium scores correlate with other measures of coronary disease. Heart scans correlate with coronary angiography, quantitative coronary angiography, carotid ultrasound (intimal-medial thickness and plaque severity), ankle-brachial index, and stress tests, including radionuclide (nuclear) perfusion imaging.

The reluctance of my colleagues to embrace heart scans stems from two issues, for the most part:

1) No study has yet been performed showing that knowing what the score is vs. not knowing what the score is changes prognosis. That's true. But it is also true of the great majority of practices in medicine. While many wrongs don't make a right, the miserable and widespread failure of other coronary risk measures, like LDL cholesterol or c-reactive protein, to readily and reliably detect hidden coronary disease creates a gaping void for improved efforts at early detection. If your LDL cholesterol is 140 mg/dl, do you or don't you have coronary disease? If your doctor's response is "Just take a statin drug anyway" you've been done a great disservice. (If and when this sort of study gets done, its huge cost--outcome studies have to be large and last many years--it will likely be a statin study. It is unlikely it will include such Track Your Plaque strategies that help reduce heart scan scores, like vitamin D and correction of small LDL particles.)

2) Fears over overuse of hospital procedures triggered by heart scans. This is a legitimate concern--if the information provided by a heart scan is misused. Heart scans should never--NEVER--lead directly to heart catheterization, stents, bypass surgery. Heart scans do not change the indications for performing revascularization (angioplasty, stents, bypass). Just because 20% of my cardiology colleagues are more concerned with profit rather than patient welfare does not invalidate the value of the test. Just because the mechanic at the local garage gouged you by replacing a carburetor for $800 when all you need was a new spark plug does not mean that we should outlaw all auto mechanics. Abuse is the fault of the abuser, not of the tool used to exercise the abuse.

All in all, while I am not a fan of legislating behavior in healthcare, the blatant and extreme ignorance of this simple tool for uncovering hidden heart disease makes the Texas action a huge success for heart disease prevention. I hope that this success will raise awareness, not just in Texas, but in other states and cities in which similar systemic neglect is the rule.

Remember: CT heart scans are tools for prevention, not to uncover "need" for procedures. They serve as a starting point to decide whether or not an intensive program of prevention is in order, and I don't mean statin vs. no statin.

Though not a multi-million dollar statin drug study, I have NEVER seen a heart attack or "need" for procedure in any person who has stopped progression or reduced their heart scan score. A small cohort from my practice was reported:

Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.

Davis W, Rockway S, Kwasny M.

The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides /=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.

Sleep: A to Zzzzzzzzzz

23. Junhu 2009 William Davis (5)

Take a look at the results from the Heart Scan Blog's most recent reader poll (399 respondents):

How many hours do you sleep per night (on average)?

9 or more hours per night
15 (3.7%)

8-9 hours per night
72 (18%)

7-8 hours per night
152 (38.1%)

6-7 hours per night
111 (27.8%)

5-6 hours per night
38 (9.5%)

Less than 5 hours per night
11 (2.8%)

Like many issues in health, too much or too little of a good thing can present undesirable consequences.

Too much sleep: While psychologists and sleep researchers advise us that at least 9 hours are required to fully eliminate sleep "debt" and achieve optimal vigilance and mental performance, epidemiologic studies have shown increased mortality with this quantity of sleep.

Too little sleep: Getting less than 7 hours habituallly increases blood sugar, appetite, inflammatory measures, and encourages weight gain. Mortality is also increased, just as with sleeping too much. It is also associated with increased likelihood of a positive heart scan score.

7-8 hours per night from a health viewpoint is that Goldlilocks "just right" value: just enough to not erode mental performance substantially, but not so little that inflammatory, insulin-disrupting, and appetite-increasing effects develop.

Of our 399 respondents in the poll, 56.1% (38% + 18%) slept what appears to be an optimal amount for health. While only 3.7% slept too much (9 hours or more), the remaining 40.1% slept too little.

Our informal poll confirms what most of us observe in everyday life: The majority of people shortchange sleep in order to meet the demands of their high-pressure, squeeze-as-much-as-possible-into-every-day lives. But not paying off your sleep "debt" is like not paying the mortgage for a couple of months. You wouldn't expect your friendly neighborhood bank to say, "Oh, you forgot to pay your mortgage? Forget about it. Just pay next month's." Sure, fat chance. But if you don't pay off your sleep "debt," you will pay it back with health.

Beating the Heart Association diet is child's play

21. Junhu 2009 William Davis (19)

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

20. Junhu 2009 William Davis (14)

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"

18. Junhu 2009 William Davis (16)

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

17. Junhu 2009 William Davis (8)

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

16. Junhu 2009 William Davis (24)

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.

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.

It doesn't matter what I eat!

9. July 2006 William Davis (0)

"How are your food choices?" I asked.

"What does it matter, doc? I take Lipitor. Doesn't that take care of it? I eat what I want!"

So declared Matthew. What he "wanted" was pretty much the diet of a teenager: pizza, cheeseburgers, soft drinks, snacks. His "beer belly" (visceral fat) gave it away. So did his blood work that showed flagrant lipoprotein abnormalities--small LDL, an HDL of 37 mg, and a severe after-eating flood of fat represented by increased "intermediate-density lipoprotein" (IDL).

Like many people, Matthew had been persuaded (or chose to believe) that LDL cholesterol was the sole cause for heart disease. Lipitor was therefore was all he needed. It must be great--how else could they afford all those slick TV commercials?

Well, it is definitely not true. In fact, with the persistence of Matthew's abnormal lipoprotein patterns, we should expect his heart scan score to continue to grow by 30%--the very same rate of increase as if he were taking nothing.

Specifically, Lipitor and drugs like it do not:

--Raise HDL.

--Correct or reduce the proportion of small LDL.

--Block after-eating flood of fat, nor do they accelerate clearance of unhealthy fats persisting in the bloodstream after eating.

Yes, what you eat does have real consequences, even if you take a statin drugs. In fact, the foods you ingest have a remarkably rapid and dramatic effect on what your blood contains. Any diabetic who checks his/her blood sugar knows this. They eat a slice of whole wheat toast and watch their blood sugar skyrocket.

Mind what you eat. Make it enjoyable, of course. But drugs do not provide impunity.

People with higher scores need to try harder

8. July 2006 William Davis (0)

Sam is a 69-year retired physician. He was thoroughly enjoying retirement: golf, travelling, going out to dinner two or three times a week, spending weekends with his grandchildren. His lifestyle tended towards overindulgence, but he managed to stay fit and trim. At 6 ft 1 inch, he weighed 194 lbs and could still run 3 miles without too much difficulty. Not as good as his marathon-running days, but still not too bad for 69.

Sam's heart scan score in 2003 was a concerning 1983--extensive plaque. His doctor wasn't much help in interpreting the scan and so Sam simply chose to ignore it.

A chance conversation with a physician friend 18 months later made Sam think that perhaps this shouldn't be ignored. That's when he came to my office.

I find that sometimes the best way to motivate someone to take action is to demonstrate just how fast plaque grows if action isn't taken. So I advised Sam to get another scan first, since 18 months had passed. His score: 2441, or a 23% increase.

Sam was now starting to catch on. We made several changes in his prevention program (starting from virtually nothing). He did undergo a stress nuclear (thallium type) of test, which he passed without difficulty--normal blood flow in all heart territories despite the extensive plaque.

But, for some reason, Sam simply allowed himself to drift back to old habits: poor choices in food, overindulging in hard liquor, missing his fish oil and other supplements, and his medication, sometimes up to several days a week.

Sam started having unusual feelings in his chest. He described a sort of nervousness along with skipped heart beats. So we repeated a stress test. This time, a large area of reduced blood flow in the front of his heart ("anterior left ventricle") was detected. Sam ended up receiving three stents in a difficult procedure.

The moral: If you're starting out with a lower heart scan score of, say, 100 or 200, maybe you'll get by without trying too hard--maybe. But if your score is higher, say, several hundred or in the thousands, you got to try harder.

You're starting later in the process. Your disease will allow you very little slack. Let your guard down and it will get you. Control over your plaque is, indeed, very possible--we do it all the time. Score reduction is also possible. But your effort must be more serious and consistent.

Money can't buy health

6. July 2006 William Davis (1)

Fallen Enron CEO, Kenneth Lay, was pronounced dead early this a.m. after suffering a heart attack.

Mr. Lay apparently had no history of heart disease and there's been no indication that symptoms provided any warning. His death was therefore classified as "sudden cardiac death".

Yet here's a man previously worth hundreds of millions of dollars with access to any test or medical system he desired--many times over. Even more recently, with his wealth reduced following his legal troubles, he and his wife managed to put away $4 million dollars to ensure an income from the interest through annuities, untouchable by the courts.

Detecting Mr. Lay's heart disease would have cost him around a few hundred dollars or whatever it costs for a CT heart scan in his city. This would have alerted his (hopefully knowledgeable) doctor that he was a time-bomb. Pile on all the stress he'd been suffering, whether deserved or no, and the diagnosis would have required little thought.

Instead, Mr. Lay has joined the thousands of Americans who will die this year because of failing to get a simple, 30-second test that costs one-tenth the cost of a stress test. Mr. Lay wasn't as lucky as former President Bill Clinton, whose doctors likewise blundered their way through and missed obvious levels of heart disease.

All Mr. Lay needed was better information: get a heart scan, then follow a program of prevention like the Track Your Plaque program. You may not have hundreds of millions of dollars, but you have the information on how to not follow in Ken Lay's footsteps. Track Your Plaque--and stay alive.

What's important, what's not in your plaque-control program

6. July 2006 William Davis (0)

Sometimes it's hard to know what is really important in your plaque-control or plaque-reducing efforts.

There are, indeed, crucial make-it-or-break-it factors that are necessary to gain control over plaque. If you hope to stack the odds of reducing your heart scan score as much as possible in your favor, then fish oil, vitamin D, 60-60-60 in the way of standard lipids, elimination of small LDL, etc. -- all the elements of the Track Your Plaque program--are necessary.

But there's lots of things that sidetrack people. I spend much of my day fielding questions from patients about all the things that either provide very little benefit for plaque control, or provide none at all.

Among the things that we have found to be too weak or useless for plaque control, or are "non-issues", include:

--Caffeine--Go ahead and enjoy a couple cups a day (though not a pot). The effect is too trivial to make much difference.

--Hawthorne--Yes, it may dilate coronary arteries modestly, but not enough to make any difference.

--Garlic--with the possible exception of a specific preparation called Aged Garlic Extract (an acqueous, non-oil-based, extract from Kyolic), garlic's effects are too tiny to help, e.g., drop in blood pressure 1-2 points. Use it, but don't expect much. Aged Garlic Extract may be an exception, in that a single study from UCLA suggested specific effects on slowing coronary plaque growth. We await more info on this.

--Anti-oxidants--There is no shortage of extravagant claims about the benefits of anti-oxidants. Unfortunately, there's very little human exerience with pine bark extract, pycnogenol, grapeseed extract, and so on. Is the purported benefit from anti-oxidation or through some other means, e.g., enhancement of nitric oxide synthase? No data.

--Policosanol--If you've followed the Track Your Plaque Special Reports, you already know what a disappointment this agent has been, despite the too-good-to-be-true clinical data. It doesn't work.

--"No-flush niacin"--Unfortunately, no flush, no effect. This high-priced supplement is still sold widely in the U.S. despite its complete lack of efficacy. It does not work in humans. (It works great in rats!)

Track Your Plaque continues to try to be the arbiter of truth in what works, what doesn't in truly stopping or reversing your coronary plaque. The proof positive? Stopping or dropping your heart scan score.

Protecting the right to use bio-identical hormones in your heart disease prevention program

4. July 2006 William Davis (0)

If you've been following the Track Your Plaque program, you know that we are advocates of "bio-identical hormones", i.e., hormone replacement using forms that are identical to the naturally-occuring human form.

In other words, we find it criminal that pharmaceutical manufacturers continue to promote use of non-identical hormones despite a probable increased side-effect and complication profile (a la Premarin). This unhappy situation persists because bio-identical hormones cannot be patent protected, meaning profits cannot be protected. Synthetic hormones can be patented and profits protected, thus their popularity among drug companies.

If that's not bad enough, Wyeth Pharmaceuticals--maker of synthetic hormone preparations, Premarin and Prempro--has filed an FDA petition to disallow the use of bio-identical hormones as prepared and dispensed by "compounding pharmacies". These are specialty pharmacies that mix and dispense hormones like estrogens (human estradiol, estriol, and estrione) and testosterone. They do so only with a doctor's prescription. Most are members of the Professional Compounding Centers of America (www.pccarx.com), a professional organization devoted to promoting quality-control over compounding practices.

Compounding pharmacies are occasionally guilty of compounding some suspect preparations. Witness the Fentanyl lollipops of 2002 in which the pain medication, Fentanyl, was put into lollipops for patients with chronic pain. This posed obvious dangers to any children who unsuspectingly ate the lollipops.

But the majority of compounding pharmacies are not guilty of such exotic practices. Most are simply pharmacies who might, for instance, mix a specific dermatologic preparation according to the orders of a dermatologist. Likewise with bio-identical hormones.

We have extensive experience with such a pharmacy in Madison, Wisconsin, the Women's International Pharmacy. They have filled hundreds of hormone prescription for us. They are responsible in their dispensing practices, in our experience. In fact, they have been at least as good, if not better, than other pharmacies we've dealt with.

We believe in protecting our rights to prescribe and you to use the choice of hormone preparations you and your doctor desire. This should include bio-identical hormones. The transparent profit motive from Wyeth should raise the hairs on your neck.

If you would like to post your comment to the FDA, there's a little time left. The folks at Womens' International Pharmacy have made it easy by posting links on their website. Go to http://www.womensinternational.com and just follow the instructions.

Here's a sample of some of the objections citizens have raised to Wyeth's petition:

I have been taking bioidentical hormones for two years. Bioidentical Hormones have been a great relief to me without the risk. I consult with my Physician who prescribes bio-identical hormones specifically for me, and my pharmacist prepares them. Without this medication and I would not be able to sleep; I would not be able to work due to the constant hot flashes. Without this medication, I find that I have less tolerance and I am considerably disagreeable. I also have problem with my memory without them. I want the bioidentcial hormones for the health benefits they provide. I urge you to not be swayed by Wyeth's petition. The product Premarin made by Wyeth, is made from pregnant horses not natural sources. Wyeth's hormones have been shown to cause cancer. I would not expect my government and its officials to submit to the highly funded petitioning of a pharmaceutical company who product is threatened by bioidentcial hormones. I do not expect my government to approved Wyeth's petition and leave me no choice of bioidentcial hormones and only the choice of Wyeth's cancer causing drugs Preamrin and Prempro. I ask that the FDA reject Wyeth's petition Docket #2005P-0411.

Another petitioner writes:

As a woman I take exception to Wyeth accusing the Compounding Pharmacy industry of unsafe practices. As a citizen of the United States I expect the FDA to stand up for my rights and the rights of all women who have found or in the future may seek consistent, safe and effective treatment with bioidentical hormones. Eliminating options by bowing to a large pharmaceutical company like Wyeth is not in the public interest and would deprive hundreds of thousands of American women from access to bioidentical hormones. Synthetic hormone replacement has been proven unequivocally unsafe in a government sponsored study and should not be forced as the sole treatment option for women. I hereby request the FDA rule against Wyeth's request. The FDA should not close down the bioidentical option of healthcare. I welcome studies of bioidentical hormones even though they are already FDA-approved and have been working effectively for decades. We already have the proof - hundreds of thousands of women, who over the past two decades have chosen bioidentical hormones based on their physicians' assessments. They are living proof that bioidentical hormones are safer and more effective and reliable than synthetic hormone drugs.

A physician and user of bio-identical hormones writes:

Wyeth, the filer of this complaint, is trying to prevent women from being able to choose less expensive compounded options for hormone replacement. There is medical evidence that in modifying the structure of their drugs (such as Premarin and Prempro) so that they could be patented, they may have introduced factors that cause the health risks identified in the Women's Health Initiative. This complaint appears to be filed for commercial purposes because of the market share that has shifted from Wyeth's products to bio-identical products from compounding pharmacies. If the complaint were upheld, patients and their doctors would not have a choice in hormone treatments. Wythe's commercial strategy of trying to eliminate the 'competition' from compounding pharmacies is against the public interest and in the interest of its own corporate profits. Women and their doctors should be able to choose between patented formulations such as those offered by Wyeth, bioidentical formulas available from compounding pharmacies, and no hormone treatment. I have been taking bio-identical hormones for several years and have had excellent results in improving my symptoms. I have been unable to take other synthetic hormones in the past, and am very concerned that my best treatment option will be taken away.

If you get a 64-slice CT coronary angiogram

3. July 2006 William Davis (0)

With new 64-slice CT scanners popping up everywhere nowadays, be sure to get your heart scan with it.

The new scanners do indeed provide wonderful images of the coronary arteries. But, say you have a 20% blockage in one artery by a coronary angiogram generated on one of these devices. What will you do in 1, 2, or 3 years when you want to know if you have progressed? Should you have the CT angiogram repeated?

Well, if you did you'll be exposed to a large dose of radiation--appropriate for a diagnostic test, but not for a screening test. The radiation exposure is not that different from undergoing a full conventional cardiac catheterization, or up to 100 chest x-rays.

"20% blockage" is also, contrary to popular opinion, not a quantitative measure. It is just an estimate of the diameter reduction at one spot. That number says nothing about the lengthwise extent of plaque. It also says nothing about the potential for "remodeling", the phenomenon of artery enlargement that occurs as plaque grows. In other words, if you had another CT coronary angiogram a year later and was told that your blockag was still 20%, in reality you could have had substantial plaque growth but it would not be reflected in that value.

People will come to me after having a CT angiogram for an opinion. Unfortunately, I send them back to their scan center to get a simple coronary calcium score. That measure is easy, quantitative, precise, and can be repeated yearly if necessary to track progression. (Track Your Plaque--I hope most of you get this by now.) Some physicians poke fun at the heart scan, or calcium, score--it's old, boring, only a measure of hard plaque. None of that's true. The coronary calcium score is a measure of total plaque (hard and soft). And when you are empowered to learn how to control and reduce your score, then it's the most exciting number in your entire health program!

Don't fall for the hype. If you go to a scan center and they insist on a 64-slice CT scanner, or if your doctor orders one, you should insist on getting a calcium score out of the test. Just ask. If they refuse, go somewhere else. Centers that refuse to generate a score have one thing on their mind: identifying people with severe blockages sufficient to obtain the downstream financial bonanza--angioplasty, stents, and bypass surgery.

If you have hypertension, think Lp(a)

2. July 2006 William Davis (0)

Clair has coronary disease.

Clair first came to attention at age 57 when she suffered a large heart attack involving the front of her heart (the "anterior wall") two years ago. Her cardiologist implanted a drug-coated stent. Her doctors advised her to "cut the fat" in her diet, exercise, and take Lipitor.

One year later, she required a stent to another artery (circumflex). At this point, Clair was thoroughly demoralized and terrified for her future. Her first heart attack left her heart muscle with only 50% of normal strength.

She came to my office for another opinion. Of course, one of the first things we did was to identify all causes of her heart disease. No surprise, Clair had 7 new causes not previously identified, including low HDL (37 mg/dl), a severe small LDL particle pattern (75% of all particles were small), and Lp(a).

Her blood pressure was also 190/88, despite her relatively slender build and 3 medications that reduced blood pressure. That's a Lp(a) effect: Exagerrated coronary risk along with unexpected hypertension that often seems inappropriate.

In fact, I saw several patients just this week with lipoprotein(a), Lp(a), and exagerrated high blood pressure (hypertension). It's not that uncommon.

Though it has not been described in the medical literature, our experience is that hypertension is a prominent part of the entire Lp(a) "syndrome".

Lp(a) is responsible for much-increased potential for coronary disease (coronary plaque). It increases in importance as estrogen recedes in a woman (pre-menopause and menopause) and testosterone in a man, since both hormones powerful suppress Lp(a) expression (though why and how nobody knows).

I believe that Lp(a) is also responsible for hypertension that most commonly develops in a persons mid-50s and onwards, often with a vengeance. 3 or 4 anti-hypertensive medications and still not controlled.

Role of l-arginine

L-arginine may be more helpful in this situation than others. L-arginine, recall, is the supply for your body's nitric oxide, a powerful dilator of the body's arteries and thereby reduces blood pressure. We use 6000 mg twice a day, a large dose that requires use of powder preparations rather than capsules.

More reading about l-arginine and nitric oxide is available through Nobel laureate, Dr. Louis Ignarro's book, NO More Heart Disease : How Nitric Oxide Can Prevent--Even Reverse--Heart Disease and Stroke, available at Amazon.com ( http://www.amazon.com/gp/product/0312335814/104-1247258-6443909?v=glance&n=283155).

Will l-arginine truly reverse heart disease on its own? No, I don't believe so. Contrary to Dr. Ignarro's extravagant claims, I find l-arginine a facilitator of plaque regression, i.e, it helps other strategies achieve regression, but it does not achieve regression or reversal by itself. (Note that Dr. Ignarro is a lab researcher who studies rats and has never treated a human being.)

But l-arginine may have special application in the person with lp(a), particularly if hypertension is part of the syndrome.

Note: As always, please note that I talk frankly about l-arginine and other supplements and medications but have no hidden agenda: I am not selling anything, nor am I affiliated with any source/website/store etc. that sells these products. If I advocate something, I do so because I truly believe it, not because I'm trying to sell something. I make this point because so much nonsense is propagated in the media because of profit-motive. That's not true here.

Dr. Ornish: Get with the program!

30. June 2006 William Davis (2)

In the era up until the 1980s, most Americans indulged in excessive quantities of saturated fats: fried chickem, spare ribs, French fries, gravy, bacon, Crisco, butter, etc.

Along came people like Nathan Pritikin and Dr. Dean Ornish, both of whom were vocal advocates of a low-fat nutritional approach. In their programs, fat composed no more than 10% of calories. This represented a dramatic improvement--at the time.

In 2006, a low-fat diet is a perversion of health. It means over-reliance on breads, breakfast cereals, pasta, crackers, cookies, pretzels, etc., the foods that pack supermarket shelves and that now constitute 70-80% of most Americans' diet.

Dr. Ornish still carries great name recognition. As a result, his outdated concepts still gain media attention. The June, 2006 issue of Reader's Digest, in their RDHealth column, carried an interview with Dr. Ornish in which he reiterates his fat-phobia.

However, on this occasion he takes a different tack. This time he rails against the "dangers" of fish oil and omega-3 fatty acids. "I've recently learned that omega-3s are a double-edged sword...In some cases, omega-3s could be fatal."

He goes on to say that, while he believes that fish oil may prevent heart attacks, it has fatal effect if you already have heart disease.

Does this make sense to you?

He's basing his views on a single, obscure study published in 2003 conducted in rural England that showed an increase in death and heart attack on fish oil. Most authorities have not taken these findings seriously, since they are wildly contrary to all other observations and because the study had some design flaws.

Despite the fact that this isolated study runs counter to all other, better-conducted studies seems not to matter to Dr. Ornish.

Clinging to the low-fat concept is like hoping 8-track tapes will make a comeback. It's not going to happen. We enjoyed the benefits while they lasted, appropriate for the era. But now, they're woefully outdated.

The overwhelming evidence is that fish oil provides tremendous benefits with little or no downside. In the Track Your Plaque program, fish oil remains a crucial supplement to gain control over your coronary plaque and stop or reduce your heart scan score. Ignore the doomsday preachings of Dr. Ornish.

(Watch for an article I wrote updating the benefits of fish oil for Life Extension magazine.)

The cholesterol fallacy

29. June 2006 William Davis (0)

Evan spotted the kiosk set up in the middle of the local mall. "Free cholesterol screenings. Know your heart health!" the sign declared.

It was a free cholesterol screening being offered by a local hospital.

The friendly nurse behind the kiosk had Evan fill out a form, then pricked his finger. Five minutes later, she reported to him with a smile, "Sir, your cholesterol is 177--your heart's fine! We get concerned when cholesterol is over 200. So you're in a safe range."

What the nurse failed to recognize is that Evan's HDL was 30 mg, a low value that actually places him at high risk for heart disease. Low HDL also signifies high likelihood of the small LDL particle pattern, a marked predisposition towards pre-diabetes and diabetes, a probable over-reliance on processed carbohydrates in his diet, a dramatically increased probability of hidden inflammation (e.g., elevated C-reactive protein), increased tendency for high blood pressure. . .

In other words, Evan's "favorable" total cholesterol is, in truth, nonsense. It's misleading, falsely reassuring, and provided none of the insight that a real effort might have yielded. Like hippies, tie-dye, other relics of the 1960s, total cholesterol needs to be put to rest. It has served many people poorly and been responsible for countless deaths.

When you see a kiosk or other service like this, even if it's free, run the other way.

"Heart disease a growth business"

29. June 2006 William Davis (0)

So announced a Boston newspaper recently, featuring a story about new heart program at a local hospital.

They were announcing how a hospital had entered the cardiovasculare procedure game and how it would boost their bottom line. The article discussed how the hospital administration was anticipating "a surge in patients from the baby boom generation."

To justify this new program, the article quoted an administrator from another hospital: "Cardiovascular issues is [sic] the number one cause people sought treatment at our hospital."

The hospital featured in the story had spent $13.5 million dollars to develop their program.

Do you think they'll make it back?

You bet they will--many times over. Hospitals are businesses, complete with a bottom line, an expectation of profit and an eye towards growth.

The hospitals in the city where I live (Milwaukee, Wisconsin) are, as in Boston and elsewhere, very aggressive--expanding into new territories, hiring new "salesmen" (physicians), all to capture more marketshare and produce more "product" (your coronary angioplasty, stent, bypass surgery, defibrillator, etc.).

The equation for hospital profits is tried and true. Ignore your heart disese risk and you can help your local hospital grow its business. Neglect to get your heart scan and you can help your hospital pay down its debt. Get a heart scan, then do nothing about it, and you may even justify a pay raise for the hospital administrators for record revenue growth and profit.

Hospitals are a growth business because of the failure of most people and their doctors to 1) identify hidden coronary disease (CT heart scan to obtain your heart scan score), then 2) seize control over it (the Track Your Plaque program or, at least, your doctor's guidance along with your efforts at prevention).

Unless you do so, you are highly likely to help your hospital boost its annual goal for procedures.
