Krill oil: Do the math

21. May 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. May 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. November 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. November 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. October 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. Add onion powder, garlic powder, salt, and pepper and simmer over low heat for 5 minutes. Add additional salt and pepper to taste. Remove from heat and set aside.

To make biscuits:
Preheat oven to 325° F.

In food chopper or processor, pulse shredded cheese to finer, granular consistency.

Pour cheese into large bowl, then add almond meal, coconut flour, baking soda, and salt and mix thoroughly. Add the eggs and butter or oil and mix thoroughly to yield thick dough.

Spoon out dough into 10 or so ¾-inch thick mounds onto a parchment paper-lined baking pan. Bake for 20 minutes or until lightly browned and toothpick withdraws dry.

Ladle gravy onto biscuits just before serving.

The Perfect Carnivore

2. October 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. September 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. September 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. August 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. August 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.

Addictive Foods

25. June 2007 William Davis (3)
Kraft Foods, Inc. is manufacturer of Kool Aid, Oscar Mayer, Kraft Macaroni and Cheese, Velveeta, Honey Maid Grahams, and hundreds of other processed food products. Post cereals also falls under the umbrella of Kraft with products like Raisin Bran, Post Toasties, and Fruity Pebbles. Annual revenues in 2006 for Kraft: $34.4 billion. A big operation with enormous influence over our eating habits.

Nabisco is manufacturer of Oreos, Ritz Crackers, Chips Ahoy and many others. Like Kraft/Post, it is also a big player.

While Nabisco was owned for several years by tobacco giant RJ Reynolds, in 2000 it was acquired by Philip Morris, another big tobacco manufacturer.

More recently in Spring, 2007, Philip Morris (now called Altria--you'd change your name, too, if it was synonymous with dirt) spun off its Kraft subsidiary for a big profit. However, the management structures remain intertwined.

In other words, despite the shuffling of shares, the two industries, big tobacco and big food, are in many respects one and the same.

Is it any surprise that the same industry that made billions of dollars pushing addictive nicotine products responsible for the deaths of hundreds of thousands of people is now intimately involved with addictive products produced and marketed by the processed food industry?

If you believe that food manufacturers are innocently and honestly conducting their businesses, simply think back to the testimony provided in front of Congress during the tobacco industry hearings. Broad deception, concealed truths, and outright lies were commonplace. There was no conscience involved. This was about money--and lots of it.

Why should the processed food industry, intimate with the tobacco industry, be any different?

If you want control over heart disease and your heart scan score, buy produce and buy local. Spend your time in the produce aisle, not the cereal or chip aisle. Unprocessed food, unadorned by bright labels, cartoon animals, American Heart Association endorsements, that's what we should seek.

Heart Scan Curiosities #7

25. June 2007 William Davis (1)



Here's a situation that crops up once in a while, occurring in perhaps 2% of heart scans.

The white within the circled area represents calcium, and thereby atherosclerotic plaque, situated immediately at the "mouth", or opening, of the the right coronary artery. What is somewhat unusual is that this plaque is not principally coronary, but aortic. That is, the plaque is mostly situated in the large vessel called the aorta. The three coronary arteries arise from the aorta.

In this instance, the aortic plaque involves the mouth of the right coronary artery. (In views not shown, the plaque also extends into the artery as well.) I call this a "double whammy" because the same plaque can post risk for heart attack and stroke.

Generally, aortic plaques pose risk for stroke. When aortic plaque fragments, little bits and pieces can travel upward to the brain and block an artery, thus a stroke.

In the coronaries, disrupted ("ruptured") plaques don't generally shower debris, but permit blood clot formation, resulting in heart attack.

This plaque, however, poses the theoretical risk of both heart attack and stroke because of its strategic location.

Should a plaque like this be handled any differently? I don't think so. But it does provide another reason to take atherosclerotic plaque in any artery seriously.

The nutrition counterculture

23. June 2007 William Davis (2)
When we look back over our American nutritional history over the last 50 years, it's hard not to come to the conclusion that much of the innovation in nutrition did not come from official agencies like the Food and Nutrition Board of the Institute of Medicine, the National Academy of Sciences, the FDA, the USDA, or the AMA.

Instead, it came from the popular culture. It came from bold, extravagant claims made by maverick figures like Ancel Keys, Nathan Pritikin, Dean Ornish, and Robert Atkins. Of course, some ideas have now fallen by the wayside, dismissed in a broad American "experiment" as ineffective, impractical, or kooky. But it permitted experimentation on an extraordinary scale with millions of people following a particular strategy at a time.

The advice of the official agencies tended to be reactionary. When nutritional deficiencies (remember those?) of the early 1900s were prevalent, they issued advice on food choices to help alleviate deficiencies. When deficiency transformed into excess after World War II, "smart" food choices from food groups and "sensible eating" became the theme.

Unfortunately, the advice was always adulterated by the enormous influence of various special interests, anxious to protect their national franchise. Powerful groups like the meat industry, wheat producers, and the dairy industry all made sure they had a big hand in crafting and influencing what was told to the American people.

The result: the advice offered by official groups has always represented the compromise of what some agency wished to convey to the people and the very powerful input of industry. What if the government decided to advise us what automobile to buy? Imagine the uproar in the auto industry when Washington tells us to buy Toyota for fuel economy and reliability. How long would that advice last?

That's why almost no knowledgeable adult follows the advice of the USDA, the National Academy of Sciences, or the Food Pyramid. I believe that we all intuitively recognize that the advice is watered-down, sometimes silly, sometimes downright unhealthy.

Nonetheless, the national experiment in diet that has taken place since 1950 has led to a collective wisdom of what is good and what is bad. The most productive conversations on nutrition therefore take place outside of the USDA and Washington. It occurs, instead, in places like bookstores, websites, and the media. Of course, there's lots of misinformation and profiteering in these sectors, as well. But like the enormous force unleashed by the collective wisdom of those contributing to the Wikipedia phemonenon, we've zig-zagged to something closer to the truth than ever uttered by an official agency.

Prescription vitamin D

23. June 2007 William Davis (32)
Niacin:

Over-the-counter: $2-5 per month
Prescription: $120 per month


Fish oil:

Over-the-counter: $3-6 per month
Prescription: $120 per month


Vitamin D:

Over-the-counter: $2 per month
Prescription: $70 per month



With vitamin D in particular, the prescription form is vastly inferior to the over-the-counter preparation. This is because the prescription form is ergocalciferol, or vitamin D2, not the effective human form, vitamin D3 or cholecalciferol.

When you're exposed to sun, what form of vitamin D is activated in the skin? It's all vitamin D3, no vitamin D2 whatsoever. Vitamin D3 is also far more effective than D2. People taking D3 (as long as it's oil-based) easily obtain healthy levels of vitamin D in the blood. People taking 50,000 units per day of D2 (the recommended quantity) remain miserably deficient, with minor increases in vitamin D blood levels. In short, D2 barely works at all. D3 works easily and effectively.

Moreover, D2 is the plant-based form. It is a form not found naturally in humans. D3 is the mammalian form, the same found in humans that exerts all its biologic benefits.

Then why is the prescription form of vitamin D2 (brand names Driscol and Calciferol) more expensive?

It's the same old pharmaceutical industry scam: Look for something patent protectable, regardless of whether it's superior to the non-patent protectable product, then sell it for exagerated profits. Though it is inferior and the science and clinical experience prove that it's inferior, you can still fool lots of people, including prescribing physicians. So what if you only make $50 or $100 million?

Don't fall for it. Prescription doesn't necessarily mean superior. In fact, the prescription form may be significantly inferior, as with vitamin D2. But the pharmaceutical industry carries such power and persuasion, who's going to know?

Nutrition activist Mike Adams

20. June 2007 William Davis (1)












I borrowed the above comic from the website of nutritionist, more properly nutrition activist and author, Mike Adams. His website, www.newstarget.com, was a pleasant surprise.

I was actually looking for some thoughts on pharmaceutical advertising and its pervasive and destructive effects and came across one of Adam's reports, Pharmaceutical television advertising is a grand hoax at http://www.newstarget.com/021526.html. The piece is a rant against the pharmaceutical industry's constant bombardment of the media, who have also been co-opted into their service, enticed by the enormous advertising revenues the drug industry brings.

But I was surprised to find an insightful, informative website on health issues, particularly healthy eating that rejects the manufactured food industry's intensive effort to persuade us to eat their products. While I don't agree with everything Adams has to say, his website provides some great food for thought. He also provides lots of downloadable information.

There's also some great laughs at his poke at the pharmaceutical industry with his Disease Mongering Engine at http://www.newstarget.com/disease-mongering-engine.asp, in which you get to create your own diseases. I got a real kick out of this.

CT scans and radiation exposure

19. June 2007 William Davis (8)


The NY Times ran an article called

With Rise in Radiation Exposure, Experts Urge Caution on Tests at

http://www.nytimes.com/2007/06/19/health/19cons.html?_r=1&adxnnl=1&oref=slogin&adxnnlx=1182254102-vQpytpx6W/Z9gvAaNPDZvA



“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.”


Where do CT heart scans fall?

Let's first take a look at exposure measured for different sorts of tests:



Typical effective radiation dose values

Computed tomography Milliseverts (mSv)

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 Milliseverts (mSv)

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


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.

A heart scan on a 16- or 64-slice multidetector device, your exposure is 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 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 legimate medical questions. They are not screening tests to be applied broadly and used year after year.

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.



Detail on radiation exposure with CT coronary angiograms on multidetector devices can be found at Hausleiter J, Meyer T, Hadamitzyky M et al. Radiation Dose Estimates From Cardiac Multislice Computed Tomography in Daily Practice: Impact of Different Scanning Protocols on Effective Dose Estimates. Circulation 2006;113:1305-1310, one of several studies on this issue.

Mediterranean diet vs. American Heart Association Diet

18. June 2007 William Davis (4)
In 1994, the Lyon Heart Study demonstrated a 50-70% reduction in coronary events in participants who followed a diet rich in vegetables, olive oil, fish, nuts, red wine, and enjoyed meals as a family activity. Various other studies have documented similar phenomena with less metabolic syndrome, better lipid patterns, less obesity with the Mediterranean lifestyle.

There are two fundamental differences between the Mediterranean diet and the diet advocated by the American Heart Association (AHA) for people with heart disease: the Mediterranean diet uses olive oil more liberally, such that fat calories can reach 40% of total; and, unlike the AHA diet, processed foods are not a part of the Mediterranean diet. Greeks, for instance, are far less likely to eat Count Chocula cereal for breakfast, or snack on Healthy Choice Premium Caramel Swirl Sandwich (ice cream sandwiches) or Malt-O-Meal Honey Nut Scooters. All three of these foods on listed on the AHA Heart-Check Mark heart-healthy program.

In other words, remove all the processed foods, and the AHA diet pretty closely resembles the Mediterranean diet. There are differences but they tend to be relatively small. If the only major difference is the presence of processed foods, wouldn't you therefore expect the AHA to embrace the Mediterranean diet?

Here's what their official stand on the Mediterranean diet states:

Does a Mediterranean-style diet follow American Heart Association dietary recommendations?

Mediterranean-style diets are often close to our dietary recommendations, but they don’t follow them exactly. In general, the diets of Mediterranean peoples contain a relatively high percentage of calories from fat. This is thought to contribute to the increasing obesity in these countries, which is becoming a concern.



The AHA is actually lukewarm towards the diet that was the first to show a dramatic decrease in heart attack and death. Why?

The answer is obvious, once cast in this light. To wholeheartedly endorse the Mediterranean diet might be seen as an indirect rejection of American processed foods. You know, the foods that have caused an extraordinary and unprecedented epidemic of obesity in the U.S., the foods that are manufactured by ConAgra, General Mills, Kelloggs--all also major financial contributors to the AHA, according to the AHA Annual Report.

I tell my patients: If you want heart disease, follow the American Heart Association diet. In my view, it is a diet founded on politics and money, not on health. How else could Cocoa Puffs be regarded as heart healthy?

Track Your Plaque in 50,000 BC

16. June 2007 William Davis (3)
Imagine we could send you back in a time machine to 50,000 BC.

However, our agreement: no modern tools or equipment. Just your brain, hands, and legs. And your landing spot will be tropical or semi-tropical, the same climate that humans spent much of their evolutionary time in.

Not only might you rub elbows with contemporaries like homo erectus and neanderthalensis, you'd also have to fend for your life and survival.

To eat, you will have to chase and kill wild game, all with your bare hands or crude tools crafted from sticks and stones. You will have to learn what wild berries, roots, and plants are edible and distingusih them from those that make you retch, make your bowels run, or kill you. You won't be able to cultivate grain, at least for a good long time, since you don't have a community that makes such an undertaking easier.

Instead, you are constantly on the run, from the moment you awake until you finally settle back as the sun sets, hopefully with a full stomach, but often empty and growling, anticipating the hunt and forage of tomorrow.

You are outdoors all day, except for the period when you hide in your cave or self-made shelter. You wear what little clothing you can make yourself from your kills, a skin or two. Your skin becomes a dark brown, a 5 foot 10 inch male will weigh 140 lbs, a 5 foot 5 inch woman 95 lbs. There are obvious downsides: your teeth will rot, you will be prone to infections, and predators view you as fair game.

But the result will be that many chronic diseases of modern life will no longer be worries for you. Heart disease? Highly unlikely. Do you need vitamin D? No, because you are outdoors virtually all day with most of your body surface area exposed to sun. Omega-3 fatty acids? You get those from the wild game you eat, since they have higher omega-3 content feeding in the wild, not eating corn like modern livestock. Since your body fat is minimal, just enough for survival, you don't need niacin.

In other words, many of the strategies of the Track Your Plaque program are modern necessities, responses to the "deficiencies" of modern life. Of course, I don't really have a time machine. I also doubt that you wish to hunt wild game every day, forage for plants and roots, run nearly-naked in the sun. You probably also have become accustomed to brushing your teeth and not viewing every animal as a potential threat to your life.

Nonetheless, I find this an interesting exercise for understanding the role of all the tools we use in the Track Your Plaque program for plaque control.

When pessimism wins

15. June 2007 William Davis (3)
When I first met Hank, I immediately sensed it: anger, hostility, fear. His heart scan score of 685 just made it worse.


He didn't want to be there talking to me. His wife was giving him a hard time. Work was a constant source of irritation. The receptionist at the front desk screwed up his paperwork. Our office charges were too much.


In short, Hank was a pessimist. A bad one.


All the nutrition information out there is bunk. Only he knew how he should eat right. It's stupid to take a lot of fish oil. "You want me to grow gills?"


Among the parameters we use in the Track Your Plaque program is blood pressure during exercise, which provides a surrogate measure of blood pressure during emotional stress, anxiety, etc. "No, I don't need that. I already exercise." No amount of justification could change his mind. "A guy at work had a stress test. They said everything was fine, then Bang! He drops dead. What good is that?"


Hank did go along with a few pieces of advice.


A repeat heart scan 12 months after the first: 870, a 27% per year rate of increase. That's about what would happen if Hank had done nothing, had taken no action to try and stop or reduce his heart scan score.


I don't know if Hank will ever succeed in dropping his score. In fact, I suspect that he will fail, meaning that plaque will grow and he will eventually, perhaps in a year, two or three, require several stents, heart bypass, or have a heart attack. In other words, Hank's pessimism is a self-fulfilling phenomenon: If he believes he will fail, he will. If he believes the world is a rotten place, it is.


Is it possible to "cure" someone like Hank of his deeply-rooted pessimistic attitudes? I don't know of any easy solutions for someone with attitudes as deeply-ingrained as Hank's. (See my prior post, "Cure for pessimism?" at http://heartscanblog.blogspot.com/2007_05_01_archive.html.)

I believe it does help to make someone aware of their attitudes and that it does indeed exert ill health-effects--if they will believe it. But this is a very tough nut to crack.

Bad news on CoQ10?

13. June 2007 William Davis (8)
A review of the effects of Coenzyme Q10 (CoQ10) on the muscle aches and weakness (myopathy) of statin drug therapy was just published in the Journal of the American College of Cardiology.

(Marcoff L, Thompson PD. The role of coenzyme Q10 in statin-associated myopathy. J Amer Coll Cardiol 2007;49(23):2231-2237.)

This is not a study, but a review of the existing scientific and clinical data available on this topic. The study authors conclude with a lukewarm statement:

". . .there is insufficient evidence to prove the etiologic [causal] role of CoQ10 deficiency in statin-associated myopathy and that large, well-designed clinical trials are required to address this issue. The routine use of CoQ10 cannot be recommended in statin-treated patients. Nevertheless, there are no known risks to this supplement and there is some anecdotal and preliminary trial evidence of its effectiveness. Consequently, CoQ10 can be tested in patients requiring statin treatment, who develop statin myalgia, and who cannot besatisfactorily treated with other agents. Some patients may respond, if only via placebo effect."

Should the media get hold of this report, be prepared for the usual "Nutritional supplement no help for drug toxicity" headlines, or "Yet another nutritional supplement shows no benefit" with parallels drawn to vitamin C or E.

There are several issue that need to be factored into the discussion:

1) This is not a study, just a review. Thus, any biases of the authors are more likely to exert themselves.

2) The understanding of CoQ10 absorption among different preparations may be an issue. I just received a mailing from Life Extension that made extravagant claims about the superior absorption of ubiquinol, to be distinguished from ubiquinone, the more common form. They claim that eight-fold increased absorption and blood levels of CoQ10 are achievable with ubiquinol. Unfortunately, virtually all the supportive data are unpublished, proprietary observations, i.e., generated by companies who make or sell it. This is as reliable as drug manufacturers who publish glowing reports on their own drugs--perhaps it's true, but it requires unbiased corroboration.

3) Despite the lack of a large, well-funded clinical trial (all are small), the issue continues to live and breathe because of the powerful anecdotal experience.

In our experience, CoQ10 does work. It doesn't work all of the time, perhaps just 80-90% of the time. It does generally require higher doses (100 mg per day, occasionally more). It very clearly must be an oil-based gelcap (just like vitamin D) to work; capsules containing powder do not work.

It's difficult to doubt when someone starts a statin drug, develops the muscle aches and weakness, begins CoQ10 and obtains distinct relief, stops CoQ10 and aches and weakness return, then only to go away again with resumption of CoQ10 . I've seen this countless times.

We do need better information on CoQ10. There's no doubt about it. For people who obtain benefit from statin therapy, I think CoQ10 remains a useful solution. A better solution would be to get rid of the offending drug. But that's not always possible--e.g., LDL cholesterol 190 mg/dl despite the best diet and "adjunctive" food effort. Then CoQ10 can be very useful.

I had a heart attack--and I don't know why!

25. October 2006 William Davis (0)
Kevin came to my office for another opinion.

A husband and father of two teenagers, Kevin had his first heart attack at age 39. Kevin received two stents to his right coronary artery. The entire process took place in a flurry with little explanation over 48 hours, start to finish.

He smoked a pack of cigarettes a day, but the only history of heart disease in his family was his father, who, also a smoker, had his heart disease uncovered in his late 70s.

His internist subsequently prescribed Zocor even though Kevin's LDL cholesterol was a relatively unimpressive 128 mg/dl.

Kevin subsequently asked his cardiologist, "Where did I get the heart disease from?"

"Cigarettes. And genetics. You can quit the first. There's nothing you can do about the second." End of explanation.

This left Kevin frightened and demoralized. If much of the cause of his heart disease couldn't be identified, why bother quitting smoking? Why not enjoy what time he had left?

Kevin was understandably shocked when I told him that genetic causes were 1)identifiable, 2)quantifiable, and 3) correctable.

Kevin's full lipoprotein analysis subsequently showed the most dire combination that commonly accounts for coronary disease in young people: Lp(a) with small LDL particles. This, along with smoking, fully accounted for this young father of two's heart disease.

Along with starting Kevin on a new program for correction of his patterns, I also persuaded him to get a heart scan. What usefulness is a heart scan after the fact? Plenty. Even though Kevin's right coronary was no longer "scorable" because the steel in the stent obscured our measurements, the two remaining unstented arteries would still yield a score. This provides a baseline for future comparison. Even after a stent, Kevin could "track his plaque".

Butter basics

24. October 2006 William Davis (3)
There’s lot of confusion about butter, margarines, and their substitutes. Butter/margarine substitutes that avoid the negative aspects and provide modest health benefits are available, but I find that people confuse what's what. So here’s a brief primer.


Butter--Avoid it. Plain and simple. Butter is a rich source of saturated fat. Of 11.5 grams total fat per tablespoon, 7.3 grams are saturated. It is not better than margarine, contrary to simple-minded reports from some media sources. Butter raises LDL cholesterol, raises blood pressure, and has been related to various cancers.

Margarine--Not better than butter, arguably worse. Some argue that the trans-fatty acids, or hydrogenated oils, used to solidify vegetable oils to make margarine solid are worse than butter. In addition to the ill-effects of butter, margarine reduces HDL and raises cancer risk, perhaps even more than saturated fats. Hydrogenation yields a very unnatural structure that modifies cellular behavior of the sort that may promote the appearance of cancer cells. More recently, however, some of the major manufacturers, like Blue Bonnet, have produced soft spread products without hydrogenation. These are reasonable substitutes when used sparingly.

Smart Balance--This is a product made with canola oil, a source of monounsaturates (the best oil source after omega-3s), but manufactured without hydrogenation and therefore has no trans-fats. It does have, in my view, a bit too much saturated fat (1.5 gm per tbsp. in the 37% Light Spread; 2.5 gm per tbsp in the 67% regular spread). This is a reasonable product to use in small quantities.

There is also a Smart Balance Omega PLUS product that contains added flaxseed oil and sterol esters. I do not recommend this product because of the sterol content (see below). I also object to the manufacturers who label their products “rich in omega-3s” when they mean linolenic acid (in flaxseed), which is converted to a trivial quantity of omega-3s. Linolenic acid may pose unique benefits of its own, but it should not be listed as an omega-3 source.

Benecol--This is a butter substitute that contains stanol esters, a substance that reduces total and LDL cholesterol. Two tablespoons a day reduces LDL around 20 mg/dl, more or less depending on your starting cholesterol.
There’s a light and regular spread. The light contains 20 calories less per tablespoon but somewhat less monounsaturates, but the same LDL-reducing stanol esters. The manufacturer does hydrogenate the oils, yielding 0.5 mg trans-fats per tablespoon--a small drawback.

Take Control--Similar to Benecol, but made with sterol esters. Take Control also reduces LDL cholesterol. However, data from several high-quality studies from Finland suggest that sterol esters may, in some people, be absorbed into the blood. This is potentially concerning. There is a rare disease called sitosterolemia that results in coronary disease in teenagers and young adults in their 20s from increased absorption of sterol esters. While you can’t acquire this genetic disease, some people have the capacity to absorb sterol esters from their intestines very efficiently. I find it very disturbing and I suggest that you stay away this product and other sterol-containing products like HeartWise orange juice and Smart Balance Omega PLUS until the issue is clarified and safety assured.

Brummel and Brown--A blend of vegetable oils (soybean and partially hydrogenated soybean) with calories and fats reduced by blending in yogurt. This is an okay product. The hydrogenation yields trans-fats below the FDA required declaration limit of 1.0 mg.
There’s also 1.0 mg each of saturated and monounsaturated fats. The calories are relatively low as a consequence of the added yogurt, only 45 calories per tablespoon. This makes the Brummel and Brown a reasonable choice.


Other products are making their way out to supermarkets. Look for the type of oil used. Canola, olive, and flaxseed are the best. Also look for trans-fats and saturated fat content; both should be low, preferably <1.0 mg per tablespoon, ideally none.

The best choice among the above products in my view is Benecol, though it’s also the most expensive. It will yield substantial drops in LDL cholesterol. All the products in our informal tastings taste a lot like butter, or at least as well as we can remember what butter tasted like! The key with all of these products is use in moderation, since they all provide between 45?80 calories per tablespoon.

Let Dr. Friedewald rest in peace

24. October 2006 William Davis (1)
In the 1960s, doctors struggled with the concept of cholesterol and its relationship to heart disease. It was becoming clear that higher levels of cholesterol were predictive of heart disease. It was also becoming clear that the low-density fraction of cholesterol, or LDL, was somewhat better than total cholesterol in predicting heart attack.

Cholesterol was easily measurable in the 1960s. LDL was not. So, Dr. Friedewald, a noted lipid researcher at the National Institutes of Health, proposed an easy method to calculate LDL cholesterol from total choleseterol, HDL, and triglycerides:

LDL cholesterol = Total cholesterol – HDL cholesterol – triglycerides/5

This simple manipulation would put LDL cholesterols into the hands of the practicing physician and the American public. Dr. Friedewald recognized that this calculation only represented an approximation of LDL cholesterol and that it was thrown off, sometimes substantially, by any abnormal rise in triglycerides or reduction in HDL. But it served its purpose at an age when most doctors hadn’t even heard of cholesterol and the public was still sold on whole milk and “farm-fresh” butter, and Chesterfields were the cigarette choice of most doctors.



The world has since changed. Most doctors have heard about cholesterol and, along with the public, have been drowned in drug company marketing for cholesterol-reducing drugs. Most people with some level of common sense and health awareness no longer use butter or whole milk, and no longer believe that the brand of cigarette you choose can be healthy. But we’re still using Dr. Friedewald’s original calculation for LDL cholesterol. When you get an LDL cholesterol from your clinic, doctor, or hospital, >99% of the time it is obtained using Dr. Friedewald’s calculation.

Is it because there’s nothing better available? No, it’s not. There’s two reasons why your neighborhood primary care physician or cardiologist is still using this dinosaur of testing called LDL:

1) The lag in science to practice is 20 years. Accept that most primary care doctors are 20 years behind the times on many issues, LDL cholesterol included.

2) Insurance companies vigorously discourage testing beyond conventional lipids. The array of objections we get from insurance companies is mind-boggling. It would be funny if human life and finances weren’t at stake. These “new” tests are “experimental”, “unproven”, not endorsed by standard guidelines, not approved by some internal committee, or simply “We don’t know what this test is” ?we’ve heard them all.

What are the tests that are superior to Dr. Friendewald’s calculated LDL? There are several, listed here in order of best to worst:

1) LDL particle number--the value generated by NMR lipoprotein testing. This is the gold standard, most reliable test available, and the one I recommend.

2) Apoprotein B--More widely available even from conventional laboratories in hospitals. Not as accurate as NMR LDL particle number, but a pretty good choice. Apo B is the principal protein in LDL, VLDL, and IDL particles, and so it’s a better reflector of risk from all of these lipoprotein fractions, not just LDL.

3) “Direct” LDL--This is LDL that is actually measured. Unfortunately, it ignores the issues of LDL size and has some other pitfalls, but it’s still better than calculated LDL

4) Non-HDL cholesterol--So-called because it incorporates all undesirable cholesterol-containing lipids except good HDL, thus “non-HDL”. This is another calculation, though better than LDL (because it sums up the risk from other apoprotein B-containing lipoproteins). Non-HDL is calculated from Total cholesterol – HDL. It’s therefore available from any standard lipid panel. It’s little used in everyday practice, however, because most people and their physicians find it confusing.

5) Friedewald calculated LDL--You can see that calculated LDL is last on a list of choices. Yet this is the measure that doctors use day in, day out. It’s the measure that drug companies base billions of dollars of revenue and profits on.

It’s an everyday occurrence in my office that calculated LDL is 89 mg/dl, but the real value is somewhere between 160 and 200 mg/dl. That’s a big difference. Imagine your realtor tells you your house’s estimated value is $200,000 and that’s what you sell it for to an eager buyer. After closing, you find out your house was really worth $300,000. You’d be upset. But that’s what you’re often getting with LDL cholesterol?a bum deal.

It’s part of the reason people will say, “My doctor said my cholesterol was fine and that no cause for my heart disease can be found. He said it was genetic.” In reality, they could have sky-high LDL cholesterol revealed by LDL particle number or apoprotein B.

Use LDL cholesterol in a pinch when you’ve got nothing else. It’s also helpful to gauge any treatment effect of diet, functional foods, drugs, etc. But it is a seriously flawed tool to diagnose your initial level of risk.

The key to losing weight

23. October 2006 William Davis (0)
I saw three people this past week, all of whom set off on an effort to lose substantial quantities of weight. And all seriously needed to.

All three started with at least 70 lbs. excess weight; all showed substantial weight-sensitive lipoprotein patterns like low HDL, small LDL, high triglycerides, VLDL, and pre-diabetic levels of blood sugar. They also all shared high blood pressure.

All three also had high heart scan scores. Kate’s score was just over 1200. Tom, a 58-year old real estate developer, had a score of nearly 600. Susan, the youngest of the three at 52, had a heart scan score of 377¾99th percentile at this age. Losing weight was an absolute requirement for their plaque control program. Because their lipoprotein abnormalities and pre-diabetic patterns were triggered by weight, weight loss would provide powerful correction. Each and every one of them would need to lose much of their excess weight¾at least 50 lbs¾if they hoped to halt the relentless progression of their heart scan scores.

All three of them returned after 6-8 weeks, and all had lost between 17-24 lbs: spectacular results.

There’s no secret to weight loss. Each of them achieved their weight loss in slightly different ways. But they also shared several critical ingredients in their weight-loss efforts:

1) All three dramatically slashed their intake of wheat flour-containing foods and other processed carbohydrates and did so consistently. All also avoided the usual high-fat, high caloric-density foods like butter, margarine, fried foods, greasy foods, nuts roasted in oil, etc. They concentrated on vegetables, salads, raw nuts, lean proteins (inc. turkey, chicken, fish, lean red meats, low-fat cottage cheese and yogurt).

2) They stopped using food as a reward or as a consolation tool.

3) Exercise for one hour a day at least 5 days a week. The exercise in 2 of 3 of these people was just walking. It wasn’t strenuous, it wasn’t expensive. The women both liked walking with friends or their spouse. Tom followed a more common male path of more strenuous work on his treadmill, elliptical, and biking at the fitness club. But they all did it religiously and missed rare sessions.

4) They refrained from any and all alcoholic beverages. Yes, there are some advantages to 1-2 glasses of wine per day, but it stalls weight loss efforts.

5) They didn’t allow themselves any major indiscretions. There were no binges, major pig-outs at weddings, barbecues, or all-you-can-eat buffets. They did allow themselves an occasional “treat” but did so in small portions.

That’s it. But for most people, that’s simply too much. Adhering to an effort to lose dramatic weight requires day-after-day consistency. Nobody can lose the equivalent of 70,000 calories (20 lbs.) just by skipping a meal, a 20-minute walk, skipping the mashed potatoes at dinner.

It can be done. You’ve just got to be consistent about it.

How can I get my lipoproteins tested?

20. October 2006 William Davis (0)
This question came up on our recent online chat session and comes up frequently in phone calls and e-mails.

If lipoprotein testing is the best way to uncover hidden causes of coronary heart disease, but your doctor is unable, unknowledgeable, or unwilling to help you, then what can you do?

There are several options:

1) Get the names of physicians who will obtain and interpret the test for you. Go to the websites for the three labs that actually perform the lipoprotein tests: www.liposcience.com (NMR); www.berkeleyheartlab.com (electropheresis or GGE); www.atherotech.com (VAP or centrifugation). None of them will provide you with the names of actual physicians. They will provide you with the name of a local representative who will know who the doctors in your area who are well-acquainted with their technology. I prefer this route to just having a representative identify a laboratory in your area where the blood sample can be drawn, because you will still need a physician to interpret the results¾this is crucial. The test is of no use to you unless someone interprets it intelligently and understands the range of treatment possibilities available. Don’t be persuaded by your doctor if he/she agrees to have the blood drawn but has never seen the test before. This will be a waste of your time. That’s like hoping the kid next door can fix your car just because he says he fixed his Mom’s car once. Interpretation of lipoproteins takes time, education, and experience.
2) Seek out a lipidologist. Lipidologists are the new breed of physician who has sought out additional training and certification in lipid and lipoprotein disorders. Sometimes they’re listed in the yellow pages, or you can search online in your area.
3) Contact us. I frankly don’t like doing this because I feel that I can only provide limited information through this method. I provide a written discussion of the implications and choices for treatment with the caveat to discuss them with your doctor, since I can’t provide medical advice without a formal medical relationship. We also charge $75 for the interpretation. But it’s a lot better than nothing.
4) Make do with basic testing. Basic lipids along with a lipoprotein(a), C-reactive protein, fibrinogen, and homocysteine would provide a reasonable facsimile of lipoprotein testing. You’ll still lack small LDL and postprandial (after-eating) information, but you can still do reasonably well if you try to achieve the Track Your Plaque targets of 60-60-60.

In 20 years, this will be a lot easier. But for now, you can still obtain reasonably good results choosing one of the above alternatives.

What do you think about those heart scans?

20. October 2006 William Davis (1)
52-year old Jerry came in for a stress test. He displayed the usual apprehension: fidgeting while he sat on the bed, examining his surroundings, asking lots of questions.

“Your doctor asked you have have a stress test?” I asked.

“All the males in my family have had heart attacks by age 56, so my doctor suggested I have a stress test,” Jerry explained.

Jerry went on to tell me that he had exercised vigorously this morning for 45 minutes without symptoms. He had, in fact, gone surfing just several weeks earlier and described how aerobically challenging it was keeping up with the 20 year olds. “But I did it!” he proudly declared.

As he neared the end of his brisk walk on the treadmill, Jerry asked, “What do you think about those heart scans?”

Jerry had asked his primary care physician the same question. His doctor had apparently told him that they were just a gimmick. “We’ll get you a real test.”

Of course, Jerry’s stress test proved entirely normal. The likelihood of an abnormal stress test with his history of vigorous exercise was <2%. I explained to Jerry that not getting heart scan would be a mistake. In fact, a heart scan was the only easily obtainable test that would uncover hidden heart disease. In truth, the stress test was a waste of time—and an unneeded exposure to radiation.

If Jerry’s heart scan score turned out to be zero, great! He was probably spared the genes from the other males in his family, and his risk of heart attack in the next decade was nearly zero.

If his heart scan turned out be 1000, then an urgent scramble to uncover the causes and correct them to create a truly effective prevention program would be crucial for his long term health. Or, perhaps his score lies somewhere in between, but Jerry would then know how far along he stood on his way to heart disease.

Don’t be a victim of the ignorance of your doctor. Despite all the attention heart scans have received, the majority of doctors remain miserably, inexcusably in the dark. I say inexcusable because CT heart scans can uncover the number one killer of Americans, the number one cause of all deaths in any primary care physician’s practices, and it’s laughably easy. How can a physician not advise patients on the value of heart scans?

If given a choice and you’re without symptoms, a heart scan is far and away the superior test.

Olive oil for gourmets

19. October 2006 William Davis (0)
"The finest extra-virgin olive oils should not be used as a medium for hot cooking, but rather as a condiment or a finisher on top of your favorite savory foods. They are expensive, but if stored properly they will last for up to a year..."

You all know that olive oil is among the preferred oils to use: rich in monounsaturates, low in saturates, high in polyphenols.




For a fascinating perspective for the olive oil gourmet, go to www.npr.org, the website for National Public Radio. (Scroll down to the article or enter olive oil into their site search.) Their article, "Like fine wines, fine olive oils boast subtle joys" provides an insightful discussion on squeezing maximum enjoyment out of this wonderful "functional food".

As we emerge from the mis-directed low-fat craze of the past 20 years, we're re-discovering the joys of healthy oils. You'll find some great thoughts here

Vitamin D must be oil-based

18. October 2006 William Davis (10)
As part of the Track Your Plaque coronary plaque reversal program, we advocate vitamin D supplementation. Vitamin D has been shown to reduce blood sugar and reduce pre-diabetic tendencies, reduce blood pressure (it's a renin antagonist, a blood pressure hormone), it's far more important for bone health than calcium, and it may help prevent colon cancer, prostate cancer, and multiple sclerosis.

And, oh yes, it may facilitate coronary plaque regression.

One lesson I've learned is that vitamin D MUST be taken as a oil-based capsule or gelcap. You'll recognize it as a transparent or translucent, sometimes opaque, capsule. The list of ingredients may say something like "cholecalciferol [vitamin D] in a base of soybean oil", indicating that the active ingredient is oil-based. Oil-based vitamin D3 skyrockets blood levels of 25-OH-vitamin D3 in to the normal range reliably and easily.


Tablets are a different story. These are generally white powdery tablets. The rise in blood levels of vitamin D3 are minimal, sometimes none. Women will often say "I get vitamin D with my calcium tablets."


People taking this form almost always have blood levels of vitamin D that are low, as if they were taking nothing.
If you're going to take vitamin D, the oil-based tablets are the way to go. They're not necessarily any more expensive. We've had good experiences with the Nature's Life 2000 unit capsule, as well as preparations from Life Extension. We have had negative experiences with the preparations from GNC, Sam's Club, and Walgreen's, all tablets and non-oil-based.

When is LDL cholesterol NOT LDL cholesterol?

18. October 2006 William Davis (0)
Darlene had a high LDL cholesterol, at times as high as 200 mg/dl. Her primary care doctor first tried Mevacor, then Pravachol, then Zocor, then Lipitor. Every statin drug failed to reduce Darlene's LDL below 160 mg/dl, even when maximum doses were used. The higher doses also resulted in nearly intolerable muscle aches and weakness.

When we sent Darlene's blood sample off for lipoprotein analysis, a surprise came back: she had a high lipoprotein(a), or Lp(a). This explained a lot.

LDL cholesterol is not always just LDL cholesterol. One of the particles that can masquerade as LDL is Lp(a). Darlene's story is typical of many people who've had high cholesterol levels poorly responsive to the statin drugs. That's because their LDL conceals Lp(a), which does not respond to these agents. LDL cholesterol does drop some because there's also some real LDL mixed in.

A poor response to statin agents or to nutritional strategies to reduce LDL is a tip-off that Lp(a) may be hidden. The answer: just measure Lp(a)! If you and your doctor don't measure it, you won't know whether or not you have it. Rather than a statin drug, we put Darlen on niacin. Not only did her Lp(a) drop, but her LDL also plummeted.

What is a desirable triglyceride level?

17. October 2006 William Davis (0)

Though well-intended, the National Cholesterol Education Panel's Adult Treatment Panel, or ATP-III, (whew!) guidelines for cholesterol have been responsible for loads of misinformation.

The intention was to educate the internist or family doctor who treats sore throats, performs Pap smears, administers pneumovax vaccine, treats arthritic knees---and dabbles in heart disease prevention. The ATP-III guidelines are the "Cholesterol for Dummies" approach.

What standard guidelines definitely do not represent are the ideal values to achieve. They do not ensure protection from heart disease. This is particularly true of the ATP-III advice to keep triglycerides at or below the "desirable" level of 150 mg/dl.

In the Track Your Plaque program, we ask "What is necessary to tip the odds in favor of coronary plaque regresion or reduction of heart scan score?" This is not achieved with a triglyceride of 150. In fact, triglycerides at this level are associated with flagrant abnormalities of lipoprotein patterns. It usually means that processed carbohydrates, particularly wheat products, are occupying too prominent a role in your food choices. It could mean that you're making excessive use of processed foods containining high-fructose corn syrup. It will not respond to a low-fat diet. It will, however, respond vigorously to fish oil.

Triglycerides are a crucial aspect of your plaque control program. We aim for 60 mg/dl or less. The ideal level is actually 45 mg/dl. At this level, all abnormal triglyceride-containing lipoproteins finally go away.

"Get regressive"

6. May 2009 William Davis (0)
This caught my eye:



Niaspan, prescription niacin, now sold by Abbott Laboratories, is now promoting its advantages in regressing coronary plaque:



In patients with a history of coronary artery disease (CAD) and hypercholesetgerolemia, Niaspan (niacin), in combination with a bile acid-binding resin, is indicated to slow progression or promote regression of atherosclerotic disease.



And the new slogan: "Get regressive."



Interestingly, the new marketing campaign is based on relatively old data. They base this new claim on 3 studies:



1) Cholesterol-Lowering Atherosclerosis Study (CLAS)--a 1987

CRP House of Cards

4. May 2009 William Davis (15)
Lew has coronary plaque with a heart scan score of 393. At age 53, that's in the 90th percentile (higher score than 90% of men in his age group).

On our search for causes of his coronary plaque, we identify low HDL of 41 mg/dl, high triglycerides of 202 mg/dl, small LDL (83% of total), calculated LDL of 133 mg/dl, and severe vitamin D deficiency with a starting blood level of 25-hydroxy vitamin D of 19 ng/ml.

His c-reactive protein: 4.1 mg/dl--above the cut-off of 2.0 mg/dl that the pharmaceutical industry is targeting as a mandate for statin therapy, particularly given the JUPITER data.

Lew instead eliminates wheat and other small LDL-provoking foods and, as a result, loses 28 lbs in 3 months; adds omega-3 fatty acids from fish oil; supplements vitamin D sufficient to increase his blood level to 70 ng/ml.

Along with dramatic correction of his starting abnormalities, his c-reactive protein: 0.4 mg/dl--no statin drug.

In my view, increased CRP is nothing more than a surrogate for the inflammatory phenomena that arise from high-carbohydrate diets, overweight, and small LDL. Correct those and CRP drops off a cliff. In fact, it is exceptionally rare for CRP to not drop to very low levels following this formula.

I believe that CRP is one more item on the list of reasons--the house of cards--the pharmaceutical industry is building to persuade us to take more and more statin drugs. LDL not low enough? Take more statin. Diabetic with low cholesterol? Take a statin. Inflammation? Take a statin.

Enough already.

At-home blood tests

2. May 2009 William Davis (6)
Our at-home blood tests are proving a hit.

So far, vitamin D is the number one most popular test, no surprise.

Second--to my surprise--is DHEA. I would have predicted it would have been thyroid testing.

Our male and female hormone panels are also proving popular.

I've personally been using the thyroid and vitamin D testing to monitor my levels. I increased my Armour thyroid based on a low free T3 value, while my vitamin D was perfect at 77 ng/ml on 8000 units vitamin D3 (cholecalciferol) per day.

The process of performing the blood spots is straightforward. The finger pricks are virtually painless using the automatic spring-loaded finger stick devices:





The number of blots to make depends on how many tests you'd like. Just a vitamin D test requires 2 blots. If 6 or more tests are ordered at a time, then all 12 blots should be made. (Two spring-loaded lancets are provided in each kit.)





If you are interested in any of our at-home blood tests, go here.

Our own Heart Hawk has posted an editorial on about blood spot testing on Health Central:

Simple, affordable home blood testing is a real game-changer in the arena of informed, self-directed healthcare. For the first time broad access to home blood testing, on a scale similar to that enjoyed by persons who routinely test their blood sugar, is available to virtually everyone and it removes doctors as the gatekeepers of these tests. Even private insurance companies and Medicare are beginning to understand the potential for improving healthcare and decreasing costs and are slowly beginning to expand coverage of home blood testing much as they do for diabetics or persons taking anti-coagulants.

"Help keep your family goiter free"

1. May 2009 William Davis (10)
People ask, "If I need iodine, should I go back to iodized salt?"

First of all, how did this notion of iodized salt originate?

In 1924, J. Edgar Hoover was appointed head of the FBI, Marlon Brando and Doris Day were born, and Calvin Coolidge was elected President of the United States. Half of American households had a car, while 1 in 4 Americans were illiterate.



In the 1920s, cities were a fraction of their current size and a third of the U.S. population, or 36 million people, lived in small rural communities.

Goiters were also wildly prevalent in 1924. Up to a third of the population in some areas of the country, particularly the Midwest, suffered from goiters, thyroid glands that enlarged due to lack of iodine.

Goiters were not only unsightly, but sometimes grotesque, causing a visible bulge in the front of the neck. Occasionally, they would grow so big that it compressed adjacent structures, like the trachea, and would have to be surgically removed. Goiters were commonly associated with thyroid dysfunction, especially low thyoid or hypothyroidism, that resulted in low IQ's in schoolchildren, debilitation in adults. Women of childbearing age delivered retarded children.

So iodine deficiency in early 20th century America was a big problem. How to solve this enormous public health problem in a large nation without television, few radios, no internet, with a largely rural and often illiterate population?

Thus was iodized salt born, a simple, technologically available solution that could be implemented on a large scale nationwide at low cost. The FDA chose this route in 1924, figuring that it was the best way to ensure that most Americans could obtain sufficient iodine through liberal use of iodized salt. Public health officials urged Americans to use salt. Morton's salt label proudly bore the slogan "Help keep your family goiter free!"

It worked. Goiters largely became a thing of the past.

How about today? The American Heart Association recommends limiting salt, recently announcing that they would like to limit intake to 1500 mg per day. The American Medical Association has been lobbying the FDA to set lower salt limit guidelines. The FDA has been clamping down on food manufacturers to reduce the quantity of salt in processed foods.

Why limit salt? The concern is that there are segments of the population (not all) that are salt sensitive, particularly African Americans, people with certain genetic forms of high blood pressure, conditions that cause water retention, and any degree of heart or kidney failure. Salt in these peoplem, in fact, can be disastrous.
So adding iodine to salt was the solution to epidemic goiter. And it worked.

But salt is not a perfect solution, just one that served its purpose back in 1924. What we need is a 21st century solution.
You will find that in the various iodine supplements at your health food store. My favorite is kelp--inexpensive, available, and a form that mimics the way Japanese people obtain iodine (though by eating seaweed, rather than with tablets).

Thumb your nose at swine flu

29. April 2009 William Davis (35)
Judging from what we know about vitamin D, it is highly probable that it confers substantial protection from viral infections, including swine flu.

Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) first connected the dots, identifying the possibility of an influence of vitamin D on incidence of flu.

In 2006, Dr. Cannell reports noticing that the patients in his psychiatric ward in northern California were completely spared from the influenza epidemic of that year, while plenty of patients in adjacent wards were coming down with flu. Dr. Cannell proposed that the apparent immunity to flu in his patients may have been due to the modest dose of 2000 units vitamin D per day he had prescribed that the patients in other wards had not been given. (Since the hospital was run by the state of California, Dr. Cannell apparently had only so much leeway with vitamin D dosing.) While it’s not proof, it’s nonetheless a fascinating and compelling observation.

A similar conclusion was reached in a recent analysis of the National Health and Nutrition Examination Survey demonstrating that the higher the vitamin D blood level, the less likely respiratory infections were.

Personally, I used to suffer through 2 or 3 episodes of a runny nose, sore throat, hacking cough, fevers and feeling crumby every winter. Over the last 3 years since I’ve supplemented vitamin D, I haven’t been sick even once. The past two years I didn’t bother with the flu vaccine, since I suspected that my immunity had been heightened: no flu either winter.

And so it has been with the majority of my patients. Since I began having patients supplement vitamin D to achieve normal blood levels (we aim for 60-70 ng/ml), viral and bacterial infections have become rare.

New research is uncovering myriad new ways that vitamin D enhances natural immune responses to numerous infections, including tuberculosis, bacteria such as those causing periodontal disease and lung infections, and viruses like the influenza virus. Enhanced immunity against cancer is also an intensive area of research on vitamin D.

Will vitamin D supplementation sufficient to achieve desirable blood levels confer sufficient immunity to swine flu should it come to your door? From what we know and what we’ve seen in the few years of vitamin D experience, I think it will in the majority. But I do believe that we should still heed public health warnings to avoid contact with others, minimize exposure to crowds, avoid travel to affected areas, etc.

Will the real LDL please stand up?

26. April 2009 William Davis (13)
The results of the latest Heart Scan Blog poll are in.

The question: How has your LDL been measured? The 187 responses broke down as:


I have only had a conventional calculated value
108 (57%)

NMR LDL particle number
35 (18%)

Apoprotein B
21 (11%)

Direct LDL cholesterol
21 (11%)

Non-HDL cholesterol
8 (4%)

I don't know what you're talking about
23 (12%)


Remember the TV game show, To Tell the Truth? Celebrities would have to guess which of three guests represented the real person, such as the notorious con man, Frank Abagnale, Jr., or Mad Magazine publisher, William M. Gaines (who stumped celebrity Kitty Carlisle, heard to exclaim, "I never figured it was him. I mean look at the way he's dressed. I was looking for someone who ran a very successful magazine, so I thought it couldn't be him!")

The celebrities playing the game were permitted to ask the three guests a series of questions, hoping to discern who was the real person vs. the two impostors. At the end, each celebrity had to guess who was truly the person of interest. "Will the real Frank Abagnale, Jr. please stand up!"

If we were to act as the celebrities in our LDL game, we quickly discover some telling facts:

--Conventional LDL cholesterol (the only value 57% of our poll respondents have had) is calculated, not measured. LDL is calculated using the 40-year old Friedewald calculation.

--Directly measured LDL cholesterol (the value 11% of respondents had) is just that: directly measured. It eliminates some of the uncertainties of calculated LDL.

--Apoprotein B-Every LDL and VLDL particle produced by the liver contains one apoprotein B molecule. ApoB therefore provides a crude particle count measure of LDL and VLDL particles. Of course, it includes VLDL and is not completely the same as just an LDL measure. Some lipid authorities Like Dr. Peter Kwiterovich have advocated that apoB replace calculated LDL, and that calculated LDL essentially be discarded.

--Non-HDL cholesterol--I mention this more for completeness. Hardly anybody uses this crude value in practice--Indeed, only 4% of our poll respondents had this measure/calculation. Non-HDL is simply total cholesterol minus HDL cholesterol = Non-HDL cholesterol. It is thus a combination of cholesterol in LDL and VLDL (triglycerides), similar to apoprotein B. While, like apoB, it is a bit different in that it includes VLDL, it has proven a superior measure of risk.

--LDL particle number--In my view, this is the gold standard for LDL and risk measurement, obtained by only 18% of our poll respondents. LDL particle number is proving superior for discriminating who is truly at risk for a cardiovascular event, particularly when metabolic syndrome or diabetes is part of the picture, i.e., when HDL and triglycerides are considerably distorted, leading to substantial corruption of calculated LDL.


While 18% is a minority, it still represents growth in recognition that conventional calculated LDL cholesterol is an unreliable, inaccurate, and outdated value. If the real LDL were to stand up, I believe that it is LDL particle number that would spring to its feet.

Vitamin D and inflammation

25. April 2009 William Davis (9)
We already know that vitamin D reduces inflammatory processes, since several markers, including c-reactive protein and IL-6 have previously been shown to drop substantially with vitamin D. Inflammation underlies coronary atherosclerotic plaque growth, as well as plaque rupture that triggers heart attack.

A German group has now shown that the important inflammatory marker, tumor necrosis factor (TNF), is also reduced by vitamin D supplementation. Many studies have implicated increased TNF levels in promoting cancer.

In this study, a modest vitamin D dose of 3320 units (83 micrograms) was given vs. placebo. The 25-hydroxy D level reached in the treated group was 34.2 ng/ml (85.5 nmol/L), which resulted in a 26.5% reduction in TNF compared with 18.7% reduction (?) in the placebo group.


Vitamin D supplementation enhances the beneficial effects of weight loss on cardiovascular disease risk markers.

Zitterman A, Frisch S et al.

BACKGROUND: High blood concentrations of parathyroid hormone and low concentrations of the vitamin D metabolites 25-hydroxyvitamin D [25(OH)D] and calcitriol are considered new cardiovascular disease risk markers. However, there is also evidence that calcitriol increases lipogenesis and decreases lipolysis.
OBJECTIVE: We investigated the effect of vitamin D on weight loss and traditional and nontraditional cardiovascular disease risk markers in overweight subjects.
DESIGN: Healthy overweight subjects (n = 200) with mean 25(OH)D concentrations of 30 nmol/L (12 ng/mL) received vitamin D (83 microg/d) or placebo in a double-blind manner for 12 mo while participating in a weight-reduction program.
RESULTS: Weight loss was not affected significantly by vitamin D supplementation (-5.7 +/- 5.8 kg) or placebo (-6.4 +/- 5.6 kg). However, mean 25(OH)D and calcitriol concentrations increased by 55.5 nmol/L and 40.0 pmol/L, respectively, in the vitamin D group but by only 11.8 nmol/L and 9.3 pmol/L, respectively, in the placebo group.


(Calcitriol = 1,25-dihydroxy vitamin D.)


Knowing your vitamin D blood level is crucial, as individual need for vitamin D varies widely from one person to the next. You can get your vitamin D tested at home by going to Grassroots Health or the Track Your Plaque Marketplace.

Even monkeys do it

24. April 2009 William Davis (6)

It all started back in the 1960s, when ape-watching anthropologists, Drs. Jane Goodall and Richard Wrangham, observed chimps foraging for a specific variety of leaf, which they consumed whole while wrinkling their noses in presumed disgust. Subsequent study showed that the leaves contained a powerful anti-parasitic compound.

A similar observation followed in 1987 by Dr. Michael Huffman from the University of Kyoto. During his year of living in the jungles of Tanzania, he observed chimpanzees in their native habitat. On one unexpected morning, he observed a female chimp, Chausiku:

“Chausiku goes directly to and sits down in front of a shrub and pulls down several new growth branches about the diameter of my little finger. She places them all on her lap and removes the bark and leaves of the first branch to expose the succulent inner pith. She then bites off small portions and chews on each for several seconds at a time. By doing this, she makes a conspicuous sucking sound as she extracts and swallows the juice, spitting out most of the remaining fiber. This continues for 17 minutes, with short breaks as she consumes the pith of each branch in the same manner.”

Dr. Michael Huffman’s description of Chausiku documents a fascinating example of animal self-medication what some call "zoopharmacognosy."
In this instance, the chimpanzee, weak, clutching her back in pain, and listless, was ingesting the leaves of the plant, Vernonia amygdalina, to purge an intestinal parasite. She recovered by the next morning.

Vernonia leaves have since been found to contain over a dozen potential anti-parasitic compounds. Chimps in this region commonly suffer infestations of parasites like Strongyloides fuelleborni (thread worm), Trichuris trichiura (whip worm), and Oesophagostomum stephanostomum (nodular worm). They have somehow stumbled onto a treatment that they administer themselves.

Chimpanzees have inhabited earth for over 6 million years. Who knows how long they and other primates have practiced some form of self-medication.

If chimpanzees can do it, I believe that we, as human primates, can also practice a similar form of self-directed health--homopharmacognosy?

Cath lab energy costs

22. April 2009 William Davis (6)
In honor of Earth Day, I thought I'd highlight the unexpectedly high carbon costs of activities in hospitals, specifically the cardiac catheterization laboratory.

A patient enters the cath lab. The groin is shaved using a plastic disposable razor, the site cleaned with a plastic sponge, then the site draped with an 8 ft by 5 ft composite paper and plastic material (to replace the old-fashioned, reusable cloth drapes). A multitude of plastic supplies are loaded onto the utility table, including plastic sheaths to insert into the femoral artery (which comes equipped with a plastic inner cannula and plastic stopcock), a multi-stopcock manifold that allows selective entry or removal of fluids through the sheath, a plastic syringe to inject x-ray dye, plastic tubing to connect all the devices (total of about 5 feet), and multiple plastic catheters (3 for a standard diagnostic catheterization, more if unusual arterial anatomy is encountered).

All these various pieces come packed in elaborate plastic (polyethylene terephthalate or other polymers) containers, which also come encased in cardboard packaging.

Should angioplasty, stenting, or similar procedure be undertaken, then more catheters are required, such as the plastic "guide" catheters that contain a larger internal lumen to allow passage of angioplasty equipment. An additional quantity of tubing is added to the manifold and stopcock apparatus, as well as a plastic Tuohy-Borst valve to permit rapid entry and exit of various devices into the sheath.

Several new packages of cardboard and plastic are opened which contain the angioplasty balloon, packaging which is usually about 4 feet in length. The stent likewise comes packaged in an 18-inch or so long package with its own elaborate cardboard and plastic housing.

At the conclusion of the procedure, another cardboard/plastic package is opened, this one containing the closure device consisting of several pieces of plastic tubes and tabs.

If the procedure is complicated, the number of catheters and devices used can quickly multiply several-fold.

By the conclusion of the procedure, there are usually two large, industrial-sized trash bins packed full of cardboard, plastic packaging, and discarded tubing and catheters. The trash is so plentiful that it is emptied following each and every procedure. None of it is recycled, given the contamination with human body fluids.

That's just one procedure. The amount of trash generated by these procedures is staggering, much of it plastic. I don't know how much of the U.S.'s annual plastic trash burden of 62 billion pounds (source: EPA) originates from the the cath lab, but I suspect it is a big number in total.

So if you are truly interested in reducing your carbon footprint and doing your part to be "green," avoid a trip (or many) to the cath lab.

Wag the Dog

20. April 2009 William Davis (7)
What if the system to provide heart care has already gotten as big as it should be?

Worse (for hospitals), what if it’s already far larger than it needs to be? Can the system continue to increase revenues if they’ve already attained titanic proportions and outgrown demand? After all, darn it, there are only so many sick people around.

Hospital administrators might have to face an unpleasant choice: downsize to strip excess capacity and suffer the consequences in a competitive market, or . . . fabricate demand for their services.

Like the Dustin Hoffman and Robert DeNiro characters in the movie, Wag the Dog, about how two media-manipulators divert public attention away from a Presidential sex scandal by fabricating a war, spin is everything. It’s enough to sidetrack public attention from a scandal, obscure a truth, send us on a useless detour.

If healthcare for the heart isn’t driven by need, but many still desire to reap the benefits of the procedure-focused system, why not increase the perceived need?

That’s precisely the course that many hospital systems have chosen to follow. If the market you serve has been tapped to its full potential, then grow the market.

Imagine if a company like General Motors were to operate this way. In 2006, for instance, GM sold 9.1 million automobiles. If GM executives were to decide that they’d like to outstrip Toyota by boosting sales by 10% to 10 million, how would they do it? They would first have to determine whether it was feasible to grow demand for their product. If deemed possible, the company would need to ramp up manufacturing capacity to anticipate increased demand. If they miscalculate, GM could be stuck with a costly surplus and have to swallow the costs, maybe selling leftovers at a loss. (We don’t mean to pick specifically on GM; they’re a fine company as far as we’re concerned. This is just a hypothetical illustration.)

But what if a company could concoct some sort of scheme to persuade the car-buying public that they just had to have their cars or trucks? In other words, they could, in effect, create demand for their products.

As perverse as it sounds, that is exactly what occurs in healthcare for heart disease. The system long ago exceeded the necessary level of infrastructure to maintain a high-quality level of care accessible to most Americans. Instead, it continues to grow through a distortion of perception, delivering more services of increasing complexity to larger and larger numbers of people.

The size of the market is therefore a manipulable thing, something that can be massaged and cultivated. There are a variety of clever ways to exaggerate the need for heart procedures.

Why not raise the alarm for heart disease every chance you get? When a local sports figure survived a heart attack here in Milwaukee, St. _____ marketing department was right there, broadcasting the process in TV ads after his recovery. What could be more American than baseball, apple pie . . . and St. _____ Hospital? After his hospital discharge, the 57-year old local icon was shown on the sidelines with his team, back on the job, and at home with family, all beaming, just three months after a bypass operation. “I received only the very best care at St. _____ Hospital. They treated me like family. St. _____ doctors and nurses are the best!” Predictably, a two-month long spike in hospital testing followed filled with people worried whether they, too, might be in imminent danger. Several local cardiologists boasted of the many sports figures who came through the stress testing and heart catheterization labs, though virtually all checked out to be fine.

Though it can serve a legitimate purpose in some situations, stress tests are the ultimate example of a heart scam built on the perception of danger. Pull people in with promises of reassuring them whether or not they have heart disease, only to provide murky results that usually do no such thing. The pitfalls of the test are turned to advantage. The all too common equivocal or mildly abnormal result can be converted into a hospital procedure. (Imagine you could perform such alchemy on the uncertain calculations on your income taxes.)

With millions of stress tests performed every year and the push to perform more and more screening tests, the market has, in effect, been expanded—even though no increase in the disease itself has actually occurred.

Beware: As the scramble for heart patients intensifies, you are going to feel like you are being pulled closer and closer into the jaws of this hungry monster called the American cardiovascular healthcare machine.
