Fat Head: Tom Naughton's manifesto for low-carb eating

12. March 2010 William Davis (16)
I just got back from Jimmy Moore's low-carb cruise to the Bahamas.

Among the many interesting people I met on the cruise was the creator of the documentary film, Fat Head, Tom Naughton.

Tom brings both creative insights into low-carbohydrate eating as well as humor. Low-carb eating can be a pretty contentious issue, but Tom made it fun. He will make you laugh about many of the odd notions we have about diet.

Among the best parts of Fat Head is Tom's portrayal of the effects of carbohydrates on insulin and fat metabolism:






Fat Head joins the ranks of films like Food, Inc, that make nutrition information entertaining. For anyone interested in a unvarnished look at diet, weight loss, along with a few laughs along the way, Tom Naughton's Fat Head is worth viewing.

Oatmeal: Good or bad?

11. March 2010 William Davis (67)

You've heard it before: oatmeal reduces cholesterol. Oatmeal producers have obtained permission from the FDA to use a cholesterol-reducing claim. The American Heart Association provides a (paid) endorsement of Quaker Oats.

I've lost count of the times I've asked someone whether they ate a healthy breakfast and the answer was "Sure. I had oatmeal."

Is this true? Is oatmeal heart healthy because it reduces LDL cholesterol?

I don't think so. Try this: Have a serving of slow-cooked (e.g., steel-cut, Irish, etc.) oatmeal. Most people will consume oatmeal with skim or 1% milk and some dried or fresh fruit. Wait an hour, then check your blood sugar.

If you are not diabetic and have a fasting blood sugar in the "normal" range (<100 mg/dl), you will typically have a 1-hour blood glucose of 150-180 mg/dl--very high. If you have mildly increased fasting blood sugars between 100 and 126 mg/dl, postprandial (after-eating) blood sugars will easily exceed 180 mg/dl. If you have diabetes, hold onto your hat because, even if you take medications, blood sugar one hour after oatmeal will usually be between 200 and 300 mg/dl.

This is because oatmeal is converted rapidly to sugar, and a lot of it. Even if you were to repeat the experiment with no dried or fresh fruit, you will still witness high blood sugars in these ranges. Do like some people and pile on the raisins, dried cranberries, or brown sugar, and you will see blood sugars go even higher.

Blood sugars this high, experienced repetitively, will damage the delicate insulin-producing beta cells of your pancreas (glucose toxicity). It also glycates proteins of the eyes and vascular walls. The blood glucose effects of oatmeal really don't differ much from a large Snickers bar or bowl of jelly beans.

If you are like most people, you too will show high blood sugars after oatmeal. It's easy to find out . . . check your postprandial blood sugar.

In past, I recommended oat products, specifically oat bran, to reduce LDL, especially small LDL. I've changed my mind: I now no longer recommend any oat product due to its blood sugar-increasing effects.

Better choices: eggs, ground flaxseed as a hot cereal, cheese (the one dairy product that does not excessively trigger insulin), raw nuts, salads, leftovers from last evening's dinner.

Mustard: Super health food?

6. March 2010 William Davis (32)
Could mustard--yes, the yellow condiment you smear on hot dogs--be a super heart healthy food in disguise?

Consider that mustard contains:

Vinegar

Turmeric

No appreciable sugar


The vinegar slows gastric emptying, resulting in slower absorption of any carbohydrates and a reduced glucose area-under-the-curve. Of the little fats contained (about 3 grams per 1/4 cup), most are desirable monounsaturates. Mustards are relatively rich in selenium, with 20 mcg per 1/4 cup, helpful for protection against cancer and thyroid disease, and magnesium, 31 mg per 1/4 cup.

Turmeric is added to most mustards. One of the constituents of turmeric, curcumin, the substance that confers the bright yellow color, has been a focus of interest for its anti-inflammatory effects. Curcumin has been documented to reduce activity of the inflammatory enzymes cyclooxygenase-2 (COX-2), lipoxygenase, and reduce activity of inflammatory signal molecules, tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1,2,6,8, and 12, and monocyte chemoattractant protein (MCP). Curcumin also has been shown to reduce LDL oxidation, a potentially important step in atherosclerotic plaque formation. Turmeric is used as a tea by Okinawans. (Hmmmm . . . )

Turmeric content of mustard can vary, of course. Likewise, sugar content. Look for mustards that are not sweetened, so avoid honey mustard in particular. Look for hot, brown, horseradish, Dijon, etc. If there is a downside to mustard, it's sodium content, though the 709 mg per 1/4 cup should only be a problem for those who are sodium-sensitive (African Americans, in particular).

So perhaps mustard isn't exactly a super health food. But it may have some bona fide health effects and should be used generously especially if you are concerned about blood sugar and inflammatory phenomena.

Exercise and blood sugar

5. March 2010 William Davis (30)
There is no doubt that exercise yields benefits across a spectrum of health: reduced blood pressure,  reduced inflammation, reduced blood coagulation, better weight control, stronger bones, less depression, reduced risk for heart attack.

Exercise also influences blood sugar. Diabetics understand this best: Exercise reduces blood sugar 20, 30, 50 or more milligrams. A starting blood sugar, for instance, of 160 mg/dl can be reduced to 80 mg/dl by jogging or riding a bicycle. (I recently had brunch at an Indian restaurant with my family. Blood sugar one-hour postprandial: 134 mg/dl. I was sleepy and foggy. I got on my stationary bike and pedalled at a moderate clip for 60 minutes. Blood sugar: 90 mg/dl.)

Could the reduction of blood sugar with exercise be THE reason that exercise and physical activity provide such substantial benefits?

Think about it. Reduced blood sugar:

1) Reduces risk for future cardiovascular events.
2) Reduces glycation of proteins, i.e., reduced glucose binding to proteins like the ones in artery walls and the lenses of your eyes.
3) Reduces blood coagulation
4) Reduces endothelial dysfunction (abnormal artery constriction that leads to atherosclerosis)

This might explain why it doesn't require high levels of aerobic activity to derive benefit from exercise, since even modest efforts (e.g., a 15-minute walk after eating) reduce blood sugar substantially.

The incredible 33-year, 18,000-participant Whitehall study tells us that a postprandial (after-eating) blood sugar of an impossibly-difficult 83 mg/dl is required to erase the excess cardiovascular risk of blood sugar. Could this simply be telling us that physical activity or exercise is required to suppress blood sugars to these low levels?

It makes me wonder if an index of the adequacy of exercise is your post-exercise blood glucose.

The most important weight loss tool

4. March 2010 William Davis (15)

Question: What is the most effective tool available to help you lose weight? 


A pedometer (walk 10,000 steps, etc.)?

A treadmill? 




A bicycle?






No. None of the above. 

The most important tool you can use to achieve weight loss is your glucose monitor:



Timing of blood sugars

3. March 2010 William Davis (5)
Because different foods generate different blood sugar (glucose) responses, the timing of your blood sugar is an important factor to consider.

This question has come up a number of times. Commenters have asked whether the one-hour postprandial glucose is timed with the start of the meal or the conclusion of the meal.

In my view, if we simply ignored all aspects of meal composition, then blood glucose should be obtained one hour after the conclusion of a meal. This is because most mixed meals (i.e., mixed in composition among proteins, fats, and carbohydrates) yield peak blood glucose levels at 60-90 minutes after consumption. Timing blood glucose to 60 minutes after the conclusion of a meal puts the sample right about at the peak.

But this is an oversimplification. For instance, here is the blood glucose behavior after so-called "complex" carbohydrates wheat bread, rye bread, rye made with beta glucan, and whole wheat pasta (50 grams carbohydrates each) in slender, healthy volunteers, mean age 29 years:


From Juntunen et al 2002

Note that blood glucose peaks at 35 minutes postprandial. (To convert glucose in mmol/L to mg/dl, multiple by 18. Thus, whole wheat bread increased blood glucose from 94 mg/dl to 122 mg/dl. Also note the lower peak glucose for pasta, but sustained higher glucose levels hours later.)

In another study, older (mean age 64 years), overweight (BMI 27.9) females with diabetes were given 50 grams carbohydrate, 50 grams carbohydrate with olive oil, or 50 grams carbohydrate with butter:


From Thomsen et al 2003. Control meal of soup plus 50 g carbohydrates ({blacktriangledown}), the control meal plus 80 g olive oil ({circ}), and the control meal plus 100 g butter (•).

In this experience, note that postprandial glucose peaks 60-120 minutes after the meals (consumed within 10 minutes), delayed more when either oil is included. Blood glucose started at 144 mg/dl and peaked as high as 230 mg/dl with carbohydrates only; peaks were reduced (along with AUC) when oil was included. (Note the differential effect, olive oil vs. butter.)

These two sets of observations give you a range of blood glucose behavior. One side lesson: Carbohydrates should never consumed by themselves, else you will pay with a high blood sugar (not to mention the hypoglycemic response later for many).

Psssst . . . There's sugar in there

1. March 2010 William Davis (13)
You non-diabetics who check your postprandial blood sugars already know: There are hidden sources of sugar in so many foods.

By now, everybody should know that foods like breakfast cereals, breads, bagels, pretzels, and crackers cause blood sugar to skyrocket after you eat them. But sometimes you eat something you thought was safe only to find you're showing blood sugars of 120, 130, 150+ mg/dl.

Where can you find such "stealth" sources of sugars that can screw up your postprandial blood sugars, small LDL, inflammation, blood pressure, and cause you to grow visceral fat? Here's a few:

Balsamic vinaigrette
Many commercially-prepared balsamic vinaigrettes, especially the "light" varieties, have 3 or more grams carbohydrates per tablespoon. Generous use of a sugar-added vinaigrette can therefore provide 12+ grams carbs. (Some, like Emeril's and Wish Bone, also contain high-fructose corn syrup.)

Hamburgers
I learned this lesson the hard way by taking my blood sugar after having a hamburger, turkey burger, or vegetarian burger (without bun): blood sugar would go way up. The effect is due to bread crumbs added to the meat or soy.

Tomato soup
If it were just tomatoes, it would still be somewhat high in sugars. But commercially-prepared tomato soup often contains added high-fructose corn syrup, sucrose, and wheat flour, bringing sugar totals to 12 to 20+ grams per half-cup. A typical 2-cup bowl of tomato soup can have upwards of 80 grams of sugar.

Granola
Sure, granola contains a lot of fiber. But most granolas come packed with sugars in various forms. One cup of Kellogg's Low-fat Granola with Raisins contains an incredible 72 grams (net) carbohydrates, of which 25 grams are sugar.


Given modern appetites and serving sizes, you can see that it is very easy to get carried away and, before you know it, get exposed to extraordinary amounts of sugar and carbohydrates eating foods you thought were healthy.

And don't be fooled by claims of "natural" sugar. Sugar is sugar--Just check your blood sugar and you'll see. So raw cane sugar, beet sugar, and brown sugar have the same impact as white table sugar. Honey, maple syrup, and agave? They're worse (due to fructose).

How low should blood sugar be?

28. February 2010 William Davis (0)
What should your blood sugar (glucose) be after eating?

Take a look at the data from the Whitehall study reported in 2006. The Whitehall Study stands apart from other studies in that it was very large (over 18,000 participants) who were observed for an unusually long time (33 years). All participants were administered a 50 gram glucose "challenge" at the start with glucose levels checked after the glucose challenge.

Here's what they found:

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

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.

Take a niacin "vacation"

20. November 2006 William Davis (2)
I've been seeing a curious niacin phenomenon that has not, to my knowledge, been reported anywhere in the medical literature.

People with lipoprotein(a), or Lp(a), are best treated with niacin, particularly given the relative lack of other effective therapies. I now have seen approximately 10 people with great initial responses to niacin, only to observe Lp(a) levels slowly drift back up to the starting level over a period of 2-3 years.

In other words, if starting Lp(a) is 200 nmol/l (approximately 80 mg/dl), drops to 70 nmol/l on niacin. Then, over 2-3 years of treatment, it drifts back to 200 nmol/l. Very frustrating.

Somehow, your body's Lp(a) manufacturing mechanism circumvents the niacin, sort of like antibiotic resistance (without the bacteria, of course).

My response to this, though untested, is to have people take an occasional "niacin vacation". I don't mean take a trip to the Bahamas while on niacin. I mean take 2 weeks off from niacin every three months or so. My hope is that the occasional vacation from niacin will allow the body to continue to respond and suppress "resistance". When resuming niacin, you may have to escalate the dose gradually to avoid re-provoking the "flush".

The same "resistance" seems to develop to testosterone in males: an initial drop followed by a gradual increase. Curiously, I've not seen this in females with estrogens, which seems to generate a durable Lp(a) suppressing effect. For this reason, an occasional testosterone "vacation" might also be considered.

So far, I've advised several people to try this. The long-term success or failure, however, is uncertain. I know of no other solutions, however.

If you have Lp(a) and are on long-term niacin, you should consider talking about this issue with your physician. Like many aspects of Lp(a), while fascinating in its complexity, much remains uncertain. Stay tuned.

When LDL is more than meets the eye

18. November 2006 William Davis (0)
Jerry wanted to know what to do with his LDL cholesterol of 112 mg/dl. "My doctor said that it's not high but it could be better."

So I asked him what the other numbers on his lipid panel showed. He pulled out the results:

LDL cholesterol 112 mg/dl

HDL 32 mg/dl

Triglycerides 159 mg/dl


I pointed out to Jerry that, given the low HDL and high triglycerides, his calculated LDL of 112 was likely inaccurate. In fact, if measured, LDL was probably more like 140-180 mg/dl. LDL particles were also virtually guaranteed to be small, since low HDL and small LDL usually go hand-in-hand (though small LDL can still occur with a good HDL).

So Jerry's LDL is really much higher than it appears. To prove it, Jerry will require an additional test, preferably one in which LDL is measured, such as LDL particle number (NMR), apoprotein B, or "direct" LDL.

It's really quite simple. Jerry likely has a high number of LDL particles that are too small. This pattern confers a three- to six-fold increased risk for heart disease.

Treatment requires more than just reducing LDL. Small LDL--an important component of this pattern, responds, for instance, to a reduction in processed carbohydrates like wheat products (breads, breakfast cereals, pretzels, etc.), NOT to a low-fat diet. Weight loss to ideal weight, especially loss of abdominal fat, will yield huge improvements in these numbers. Niacin may be a necessary component of Jerry's treatment program, since it increases LDL size and raises HDL.

For more discussion on measures superior to LDL cholesterol, see my upcoming editorial, Let Dr. Friedewald Lie in Peace (an expansion of a previous Heart Scan Blog). It will be posted on the Cardiologist on Call column on the Track Your Plaque website within the next week.)

Oil-based vitamin D

14. November 2006 William Davis (2)

As time passes, I gain greater and greater respect for the power of restoring vitamin D blood levels to normal, i.e. 50-70 ng/ml. Just yesterday, I saw several people with blood levels of <10 ng/ml--severe deficiency.

Vitamin D deficiency this severe poses long-term risk for osteoporosis, arthritis, colon cancer, prostate cancer, inflammatory diseases, diabetes, and heart disease. Vitamin D appears to make coronary plaque reversal--reduction of your heart scan score--easier and faster.

But it is important that you take the right kind of vitamin D. Several of the people I saw yesterday with vitamin D levels of somebody living in total darkness were taking vitamin D, but they were taking tablets. Tablets are the wrong form. Powder-based tablets, in my experience, yield little or no rise in blood levels. Some preparations generate a small rise but the dose required is huge.

If you're going to take vitamin D, take a preparation that yields genuine and substantial rises in blood levels. This requires an oil-based capsule. I commonly see blood levels of 25-OH-vitamin D3 rise from, say, 10 ng/dl to 60 ng/ml when oil-based capsules are taken.

The most common dose I prescribe to patients is 2000 units per day to females, 3000-4000 units per day to males in non-sun exposed months. Ideally, your dose is adjusted to blood levels.

The Vitamin Shoppe preparation pictured here is one I've used successfully and generates bona fide rises in blood levels. And it costs around $5. Just be sure the preparation you buy is oil-based.

For rapid success, try the "fast" track

14. November 2006 William Davis (1)
Have you tried fasting?

Before your eyes glaze over, let me tell you what I mean. I don't mean a water-only fast for two weeks while you drool over all the temptations around you and you feel sorry for yourself.

I also don't mean the juice fasts that some people use that turn into fruit juice fasts of pure sugar.

Here's another way to do it. Usually, 48 hours of doing this will yield several benefits:

--Weight loss of 1 lb. You will likely experience an even greater weight loss of 2-4 lbs, but much of this will be water loss.

--If you're like me and share a heightened sensitivity to sugars and carbohydrates (like wheat), you may find out just how awful you feel when you eat certain foods. Many people tell me they feel absolutely wonderful when they fast--clearer thinking, increased energy, improved mood. Not the constant gnawing urge to eat they expected.

--After your fast is over, you look back and realize just what large portions of food you were eating. You'll be content with smaller quantities--and enjoy it more.


The "fast" I've used successfully includes two foods:

1) Vegetable juices--that you either juice yourself or purchase. V8 or its equivalent works pretty well. Though purchased V8 is not the best, it's better than nothing and does work reasonably well. If you juice your own vegetable juices, watch out for the diarrhea if you're unaccustomed to vegetable juices. Four 8 oz glasses per day works well.

2) Soy milk--for a source of protein and modest quantity of sugar and fat. I like the Light Silk Soymilk (Vanilla) which contains 80 calories, 2 g fat (0.5 g monounsaturated), 7 g sugar, 6 g protein per 8 oz glass. Four 8 oz glasses of soymilk also work well. In my neighborhood, 8th Continent is another good choice.


Sip both of these throughout the day. Of course, drink water in unrestricted amounts.

What can you expect in your coronary plaque control/heart scan score reversal program? When the fast is over, a rise in HDL, reduction in small LDL, reduction in triglycerides, reduction in blood sugar and insulin, and a smaller tummy. This strategy can be useful to kick-start weight loss efforts or as a periodic way to maintain control over weight and lipid/lipoprotein patterns.

No flush = No effect

13. November 2006 William Davis (3)


"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan

11. November 2006 William Davis (1)

Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

10. November 2006 William Davis (1)
Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

8. November 2006 William Davis (0)
A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

7. November 2006 William Davis (0)
Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

6. November 2006 William Davis (0)
Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

Are happy people more likely to reduce heart scan scores?

18. December 2006 William Davis (0)
I was talking to Darryl, a patient today: 71 years old with a heart scan score of 378, as well as an enlarged aorta (4.5 cm).

We had identified numerous lipoprotein abnormalities 12 months ago and advised him on a program for correction. His patterns included small LDL, high triglycerides, sky-high IDL (VERY important when you have an enlarged aorta), and lipoprotein(a). Blood pressure was also high, another crucial fact to correct when the aorta is enlarged.

Anyway, Darryl corrected lipoproteins to perfection: basic lipids were substantially better than 60-60-60; lipoprotein(a) was reduced well into the desirable range; IDL was eliminated; blood pressure was 108/64. Repeat heart scan score: 354.

There's nothing spectacular about Darryl's story, except that, despite these issues, Darryl was a happy man. He smiled throughout our conversation. He has told me on several occasions how grateful he is for the life he has.

Darryl is not wealthy. He retired around 4 years ago and fills his day with helping his wife, walking outdoors, helping out at his church, and contributing to the care of his grandchildren. Through all this Darryl is incurably, unfailingly, and irrepressibly happy.

It made me think back through all the other people who've also had great succes in their Track Your Plaque program. It struck me that, for the most part, they too were a happy bunch: generally optimistic, happy, not overly stressed nor prone to extremely stressful responses to stressful situations. All seem to also be grateful for the good in their lives, though most had no more money than the average person and had their share of difficulties in life. In fact, I can only recall one person who reversed coronary plaque who was an angry, pessimistic personality. Just one.

Could it be that happy, optimistic people are more likely to reverse coronary plaque? It would, after all, be consistent with all the other observations that type A personalities have more heart attack, etc.

Anyway, this is just an informal observation but one that seems very consistent. Track your plaque--and be happy!

Don't overdo the vitamin D

17. December 2006 William Davis (1)
As time passes and I advise more and more people to supplement vitamin D, I gain increasing respect for this powerful "vitamin". I am convinced that vitamin D replacement is the reason for a recent surge in our success rates in dropping CT heart scan scores. I believe it is also explains the larger drops we've been witnessing lately--20-30%.

But vitamin D can be overdone, too. Too much of a good thing . . .

Despite being labeled a "vitamin", cholecalciferol is actually a hormone. Vitamins are obtained from food and you can thereby develop deficiencies because of poor intake. Deficiency of vitamin C, for instance, arises from a lack of vegetables and fruits.

Vitamin D, on the other hand, is nearly absent from food. The only naturally-occuring source is oily fish like salmon and sardines. Milk usually has a little (100 units per 8 oz) because milk producers have been required by law to put it there to reduce the incidence of childhood rickets.

A woman came to me with a heart scan score of nearly 3800, the highest score I've every seen in a woman. (Record for a male >8,000!) She was taking vitamin D by prescription from her family doctor but at a dose of 150,000 units per week, or approximately 21,000 units per day. This had gone on for about 3-4 years. This may explain her excessive coronary calcium score. Interestingly, she had virtually no lipoprotein abnormalities identified, which by itself is curious, since most people have some degree of abnormality like small LDL. Obviously, I asked her to stop the vitamin D.

Should you be afraid of vitamin D? Of course not. If your neighbor is an alcoholic and has advanced cirrhosis, does that mean you shouldn't have a glass or two of Merlot for health and enjoyment? It's a matter of quantity. Too little vitamin D and you encourage coronary plaque growth. Too much vitamin D and you trigger "pathologic calcification", or the deposition of calcium in inappropriate places and sometimes to extreme degrees, as in this unfortunate woman.

Ideally, you should have your doctor check your 25-OH-vitamin D3 blood levels twice a year in summar and in winter. We aim for a level of 50 ng/ml, the level at which the phenemena of deficiency dissipate.

"It must have been the statin"

13. December 2006 William Davis (0)
After four years of trying, Randy finally reduced her heart scan score. It not only dropped, it plummeted. After four previous scans that showed 25% or more increases, she'd finally dropped her score 23%. (I Blogged about Randy's case a few weeks ago.)

Randy also works for a cardiologist. When she told him that she had reversed her coronary plaque and reduced her heart scan score by 23%, he said, "It must have been the statin agent."

Randy was indeed on a statin drug at a low dose. But she also had taken great efforts in exercise, food choices, fish oil, and vitamin D. In fact, her score had progressed dramatically while she was taking the drug. Put simply, it was not the statin.

But that is the mindset of the conventionally thinking cardiologist. Stent, bypass, or statin drug--what else is there? Even with crystal clear evidence for coronary plaque regression, they refuse to acknowledge that tools that are not in their everyday consciousness could have achieved so spectacular a result.

Given a choice, 9 out of 10 cardiologists would rather put a stent in and walk away $2000 richer for an hour of work. Don't allow them to have this choice. Take control now.

Statin Drugs May Help the Healthy:
Cholesterol-Lowering Statin Drugs May Benefit People Without Heart Disease

That's the headline on WebMD, reporting the findings of a recent study published in the Archives of Internal Medicine. In reality, it wasn't really a study at all, but a re-analysis of previously published data, a so-called meta-analysis.

Nonetheless, the University of Toronto group re-analyzed the results of several studies, pooling data on 28,000 people, none of whom had known coronary disease. The results were similar to the results of the studies that were reported individually: a 29% reduction in heart attack and other "events" in people taking statin drugs.

What's surprising to me is this notion that statins, or any other treatment for that matter, prevent heart attack in people without heart disease. This is idiotic. Of course they had coronary heart disease. You can't have a heart attack in the absence of coronary disease. (There are very rare exceptions, like cocaine users, who experience coronary spasm from the drug).

What the study shows is that people with unrecognized heart disease experienced a reduction in heart attack. What it also means is that many, many people truly without heart disease were unnecessarily treated. As you'd predict, the drug manufacturers love this sort of broad, untargeted use of their drugs. It's an approach that brings in billions of dollars of revenues. The article on WebMD, in fact, was accompanied by three ads for various cholesterol drugs on this single page story.

What if only people with heart disease, as identified by CT heart scan scores, were treated? You would indeed witness an even larger reduction in heart attack risk, because the group receiving treatment both has the disease and is thereby at greater risk. Treatment should yield even greater risk reduction than treating broad groups who superficially appear to not have heart disease.

Ignore this nonsense about statin drugs reducing heart attack risk in people without heart disease. If you don't look for it, you won't know you have it. Once again, you can be lots smarter than the media. Get a heart scan and find out if your risk is worth reducing.

Heart attack guaranteed

10. December 2006 William Davis (0)
What if you knew for a fact that your risk for heart attack was 100% by, say, age 58? This is indeed true for many people, though at age 60, 65, 70--or 45.

In other words, unless something were done about the causes of heart disease, you would inevitably suffer a heart attack at 58.

What sort of action could you take at age 45?

Obviously, not smoking is an absolute requirement. Continue and you may as well start getting your affairs together.

How about exercising and eating a generally healthy diet? Will your risk be reduced to zero? No. It might be reduced 20-30%, depending on genetic factors.

How about a statin drug? Watch TV ads during Oprah, and you might think it's a cure. But in reality, while it is a financial bonanza for the drug manufacturers, it will reduce risk for heart attack by 30%.

(Note that risk reduction by following multiple strategies is not necessarily additive. In other words, if you have a healthy lifestyle and take a statin agent, is risk reduced 60% (30 + 30)? No, because the effects may overlap.)

So, eating healthy, exercising, and taking a statin drug might reduce risk 35-40%, maybe 50% in the best case scenario. Would you be satisfied? Most would not.

Add fish oil at a truly therapeutic dose. Risk reduction by itself: 28%.

Add niacin or other strategies for correction of your individual, specific causes of heart disease: Now we're up to 90% reduction.

Throw in a tracking process to prove whether or not atherosclerotic plaque has progressed or reversed. Now we're approaching 100% if plaque reverses. The only way I know how to track plaque is through CT heart scans. What other test is readily available to you with low radiation exposure, yet is relatively inexpensive and precise? It certainly is not stress testing, heart catheterization, CT angiograms, or other techniques. Cholesterol won't tell you. Besides CT heart scans, there's nothing else I know of.

Let's fact it: For many people, uncorrected risk for heart attack is truly 100% at some age. Take action while you can.

That, in a nutshell, is the Track Your Plaque program.

Heart scan curiosities 3

This is a sample image from the heart scan of a 54-year old, 212 lb, 5 ft 2 inch woman. The heart is the whitish-gray in the center; lungs are the dark (air-filled) areas on either side of the heart. Note the massive amount of surrounding gray tissues that encircles the heart and lungs. This is fat. At this weight, the diameter of total fat exceeds the combined diameter of the heart and lungs. If we were to show the abdomen, there would be even more fat. (The image shows the body not well centered because the technologist centers the heart, since this is, after all, a heart scan.)





This is a 55-year old, 151 lb, 5 ft 4 inch woman. Note the contrast in the quantity of fat tissue surrounding the chest, a much more normal appearance. Note that this woman is still around 25 lb over ideal weight, but not to the extreme degree of the woman above.

Another curious observation: Note the more whitish streaking in the heavier woman's lungs. Heart scans are performed while holding a deep inspiration (a deep breath inwards), mostly to eliminate lung respiratory motion during image acquisition. Nonetheless, the heavier woman's lungs are not as fully expanded as the more slender woman. In other words, the heavier woman cannot inflate her lungs as effectively as the thinner woman. Ever notice how breathless heavy people are? Some of this effect is just being out of shape. But there's also the added effect of the abdominal fat exerting upwards compression on the lung tissues, and the constrictive effect of the encircling fat mass. At the beginning of inspiration, the chest fat exerts the resistance of inertia to inspiration that is absent, or less, in a slender person. With each breath, the heavy woman must move 50 lbs or so of surrounding fat mass just to inhale.

The heavier woman is, in effect, suffocating herself in fat.

The distortions to the human body incurred by extreme weight gain are both fascinating and shocking. I hope you're breathing easily.

The shameful "standard of care"

10. December 2006 William Davis (1)
John's initial heart scan four years ago showed a score of 329. His physician prescribed Zocor for a somewhat high LDL cholesterol.

One year later, John asked for another scan. His score: 385, a 17% increase. John exercised harder and cut his fat intake.

This past fall--3 years after his last scan--John had yet another heart scan. Score: 641, a 66% increase over the last scan, all the while on Zocor.

John sought an opinion from a reputable cardiologist. He concurred with the prescription of Zocor and advised annual stress tests. That's it.

Followers of the Track Your Plaque approach know that the expected uncorrected rate of increase in heart scan score is 30% per year. On Zocor or other cholesterol reducing statin agent, a common rate of growth is between 18-24% per year--better but not great. Plaque growth is certainly not stopped.

But that is the full extent of interest and responsibility of your cardiologist. Prescribe a statin drug, perform a stress test, and the full extent of his obligation has been fulfilled. In legal terms, your physician has met the prevailing
"standard of care". No more, no less.

In other words, the prevailing standard of care falls shamefully short of what is truly possible. For the majority of the motivated and interested, coronary plaque reversal--reduction of your heart scan score--should be the standard aimed for. It's not always achievable, but it is so vastly superior to the prescribe statin, wait for heart attack approach endorsed by most cardiologists.

Heart scan curiosities 2

9. December 2006 William Davis (2)


This is an example of a so-called "hiatal hernia", meaning the stomach has migrated through the diaphragmatic hiatus into the chest--the stomach is literally in the chest. This example is an unusually large one. Hiatal hernias can cause chest pain, indigestion, and a variety of other gastrointestinal complaints. Heart scans are reasonably useful to screen for this disorder, though very small ones could escape detection by this method.

Sometimes, you can actually hear the gurgling of stomach contents (the common "growling" stomach) by listening to the chest. Large ones like this actually crowd your heart (the gray structure above the circled hernia), irritating it and even causing abnormal rhythm disorders. The dense dark material within the hernia represents lunch.

I would not advocate CT heart scans as a principal method to make a diagnosis, but sometimes it just pops up during a heart scan and we pass it on to the person scanned.

Vitamin D: New Miracle Drug

6. December 2006 William Davis (0)
At the meetings of the American Society of Bone and Mineral Research, Dr. Bruce Troen of the University of Miami detailed his views on the extraordinary benefits of vitamin D replacement. He also talked about the enormous problem of unrecognized vitamin deficiency.

“There’s a huge epidemic of hypovitaminosis D, and the real key here is not just that it’ll benefit you from a bone and neuromuscular standpoint, but if you correct hypovitaminosis D and the corresponding secondary hyperparathyroidism, then you’re going to decrease prostate cancer, colon cancer—actually “up to 17 different cancers, breast cancer included.”

Unfortunately, Dr. Troen did not talk much about the heart benefits of vitamin D, likely since the data is scant, nearly non-existent. However, if the Track Your Plaque experience means anything, I predict that vitamin D replacement will become among the most powerful tools you can use to gain control over coronary plaque.

Read the text of a report from the Internal Medicine World Report to read more of Dr. Troen's comments.

Heart disease "reversal" by stress test

5. December 2006 William Davis (3)

Here's an interesting example of a 71-year old man who achieved "reversal" of an abnormality by a nuclear stress test.

This man underwent bypass surgery around 10 years ago, two stents three years ago. A nuclear stress test in April, 2005 showed an area of poor blood flow in the front of the heart. On the images, normal blood flow is shown by the yellow/orange areas. poor or absent blood flow is shown by the blue/purple areas within the white outline.

Now, I can tell you that this man is no paragon of health. He's only accepted limited changes in his otherwise conventional program--in other words, someone who I'd be shocked achieved true reversal of his heart disease. (I didn't have him undergo any CT heart scans because of the difficulties in scoring someone who has undergone bypass surgery and stents, and because of limited motivation. True plaque reversal is for the motivated.)This patient did, however, accept adding fish oil and niacin to his program.

Nonetheless, stress testing can be helpful as a "safety check". Here's the follow-up stress test:
You'll notice that the blue/purple areas of poor blood flow have just about disappeared. This occurred without procedures.

Does this represent "reversal"? No, it does not. It does represent reversal of this phenomenon of poor flow. It does not represent reversal of the plaque lining the artery wall. That's because improvement of flow, as in this man, can be achieved with relatively easy efforts, e.g., improvement in diet, statin drugs, blood pressure control, etc. True reversal or reduction of coronary plaque, however, is tougher.

If blood flow is improved, who cares whether plaque shrinks? Does it still matter? It does. That's because the "event" that gets us in trouble is not progressive reduction in blood flow, but "rupture" of a plaque. A reduction in plaque--genuine reversal--is what slashes risk of plaque rupture.
