60-year old man dies of high cholesterol

1. February 2012 William Davis (12)
Never saw a headline like this? Neither have I. That's because it doesn't happen.

Cholesterol doesn't harm, maim, or kill. It is simply used as a crude--very crude--marker. It is, in reality, a component of the body, of the cell wall, of lipoproteins (lipid-carrying proteins) in the bloodstream. It is used a an indirect gauge, a "dipstick," for lipoproteins in the blood to those who don't understand how to identify, characterize, and quantify actual lipoproteins in the blood.

Cholesterol itself never killed anybody, any more than a bad paint job on your car could cause a fatal car accident.

What kills people is rupture of atherosclerotic plaque in the coronary arteries. For all practical purposes, you must have atherosclerotic plaque in order for it to rupture (much like a volcano erupts and spews lava). It's not about cholesterol; it's about atherosclerotic plaque. Plaque might contain cholesterol, but cholesterol is not the thing itself that causes heart attack and death.

So why do most people obsess about cholesterol? Good question. It is, at best, a statistical marker for the possibility of having atherosclerotic plaque that ruptures. High cholesterol = higher risk for heart attack, low cholesterol = lower risk for heart attack. But the association is weak and flawed, such that people with high cholesterol can live a lifetime without heart attack, people with low cholesterol can die at age 43.The same holds true for LDL cholesterol, you know, the calculated value based on flawed assumptions about LDL's relationship to total cholesterol, HDL cholesterol, and VLDL cholesterol.

A crucial oversight in the world of cholesterol: There are many other factors that cause atherosclerotic plaque and its rupture, such as inflammatory phenomena, calcium deposition, artery spasm, hemorrhage within the plaque itself, degradative enzymes, etc., none of which are suggested by cholesterol measures.

But one observation has held up, time and again, over the past 40 years of observations on coronary disease: The greater the quantity of coronary atherosclerotic plaque, the greater the risk of atherosclerotic plaque rupture. An increasing burden of atherosclerotic plaque along the limited confines of coronary arteries, just a few millimeters in diameter and a few centimeters in length, is like a house of cards: It's bound to topple sooner or later, and the bigger it gets, the less stable it becomes.

If you are concerned about future potential for heart disease and heart attack, don't get a cholesterol panel. Get a measure of coronary atherosclerotic plaque.

Back to basics: Coronary calcium

30. January 2012 William Davis (42)
After having my attentions pulled a thousand different directions these past 6 months, with the release of Wheat Belly and all the wonderful media attention it has attracted, I've decided to pick up here with a series of discussions about the fundamental issues important to the Track Your Plaque program and prevention and reversal of coronary atherosclerotic plaque.

I fear the discussions at times have drifted off into the exotic. This is great because this is how we learn new lessons, but we can never lose sight of the basics, else we risk losing control over this disease.

Imagine you've got a beautiful new car. You wax it, gap the spark plugs, rotate the tires, etc. and it looks brand-new, just like it came off the dealer's lot. 50,000 miles pass, however, and you realize you've forgotten to change the oil. Ooops! In other words, no matter how meticulous the attention to transmission, tires, and paint job, neglect of the most basic responsibility can ruin the whole thing. We can't let that happen with heart health.

If we propose to reverse coronary atherosclerotic plaque, we've got to have something to measure. First, it tells us whether we have atherosclerotic plaque in the first place, the stuff that accumulates and blocks flow and causes anginal chest pains, and ruptures like a little volcano and causes heart attacks. Second, it gives us something to track over the years to know whether plaque has grown, stopped growing, or been reduced. Without such a measure, you will be driving without a speedometer or odometer, just guessing whether or not you've gotten to your destination.

Of course, the conventional approach to heart disease and heart attack is not to track atherosclerotic plaque in your coronary arteries, but to track some distant "risk factor" for atherosclerotic plaque, especially LDL cholesterol. But LDL cholesterol is flawed at several levels. First, it is calculated, not measured. The nearly 50-year old Friedewald equation used to calculate LDL cholesterol is based on several flawed assumptions, yielding a value that can be 20, 30, or 50% inaccurate as a rule, only occasionally generating a value close to the real value. (No point in publicizing this problem, of course: Why compromise a $27 billion annual cash cow?) It also ignores the effect of diet. (No, cutting fat does not reduce LDL for real, only the calculated value. Cutting carbohydrates, especially wheat--"healthy whole grains"--slashes measured LDL values like NMR LDL particle number and apoprotein B.)

But all risk factors are, at best, snapshots of the situation at that moment in time. They change from day to day, week to week, month to month, year to year. If you do something dramatic in health, like lose 50 pounds, you can substantially change your risk factors values, like LDL cholesterol and HDL cholesterol. But you may not modify the amount of atherosclerotic plaque in your heart's arteries.

Measuring the amount of atherosclerotic plaque in your heart's arteries is, in effect, a cumulative expression of the effects of risk factors up until the moment of measurement.

There are several stumbling blocks, however, in the concept of measuring coronary atherosclerotic plaque. We cannot measure all the unique components of plaque, such as fibrous tissue like collagen, or degradative enzymes like collagenases, or inflammatory proteins like matrix metalloproteinase, or the debris of hemorrhage and inflammation. We struggle to contemporaneously mix in measures of bloodborne inflammation, coagulation and viscosity, and physiological phenomena of the artery itself, like endothelial dysfunction, medial (muscle) tone, and adventitial fat.

So we are left with semi-static measures of total coronary atherosclerotic plaque like coronary calcium, obtainable via CT heart scans as a calcium "score." No, it is not perfect. It does not reflect that moment's blood viscosity, it does not reflect the inflammatory status of the one nasty plaque in the mid-left anterior descending, nor does it reflect the irritating sheer effects of a blood pressure of 150/95.

But it's the best we've got.

If anyone has something better, I invite you to speak up. Carotid ultrasound, c-reactive protein, ankle-brachial index, stress nuclear studies, myoglobin, skin cholesterol, KIF6 genotype . . . none of them approach the value, the insight, the trackability of actually measuring coronary atherosclerotic plaque. And the only method we've got to gauge coronary atherosclerotic plaque that is non-invasive and available in 2012? Yup, a good old CT heart scan calcium score.

Myocardial infraction

15. January 2012 William Davis (45)
I've seen a few heart attacks this past year . . . but none in the people who follow this program.

I saw a heart attack in a priest, a wonderful man who was unable to say "no" to his parishioners who insisted on bringing pies, cakes, and cookies every day.

I saw an impending heart attack in a 74-year old man, a football coach who thought the whole wheat-free, low-carb thing was some wacko trend. Four stents later, he's changed his mind.

A 69-year old woman had to be hospitalized for heart failure due to partial closure of an artery. She repeatedly told me that she simply could not follow the diet because it was "too restrictive."

There were a few others. Interestingly, all felt they were eating healthy, minimizing junk foods and avoiding fatty foods. None were wheat-free nor restricted carbohydrates.

In other words, in the people who follow the basic advice of the Track Your Plaque program to do such simple things as eliminate wheat, don't indulge in junk carbohydrates, normalize vitamin D status, supplement omega-3 fatty acids, supplement iodine and correct any thyroid dysfunction . . . well, they have no heart attacks.

Diet is superior to drugs

7. January 2012 William Davis (27)
Might-o’chondri-AL left this wonderful record of his lipoprotein experience in the comments to the last Heart Scan Blog post. It is a great example of what is achievable with diet and a few supplements . . . without drugs.


(A) Jan. 2011 1st ever NMR lipo-protein analysis was done after 4 months of consistent home food prep of pretty low fat (only olive oil and 1 tablespoon coconut oil daily) but plenty of whole wheat and half potatoes:
* LDL # of particles (P) = 1,676 in nmol/L————being a LDL cholesterol (C) reading of 139 mg/dL
* small LDL # P = 1,021 nmol/L —————yikes! you advise smLDL be less than 117 nmol/L
* HDL # of particles = 28.8 umol/L ————–being a HDL C reading of 45 mg/dL
* Triglycerides = 90 mg/dL ————– true, I never struggled with my weight

(B) May 2011 2nd NMR after another 4 months but added in more fat (1 teaspoon highly concentrated fish oil daily, 90% chocolate, handfulls of nuts, more olive oil and kept coconut oil at 1 tablespoon daily for a controlled experiment), added 500 mg Niacin 3 times a day (in stages up to1,500 mg. total daily), 6000 IU daily vitamin D, deliberately cut out all grains except for social politeness and substituted in daily Koji fermented brown rice (rustic Amazake):
** LDL # P……………= 976 nmol/L ——————————– being LDL C of 100 mg/dL
** small LDL # P …. = 96 nmol/L ——————————– nice surprise
** HDL # P ………… = 27.3 umol/L ——————————being an increase to HDL C of 64 mg/dL
** Triglycerides …… = 42 mg/dL ——————————– despite daily carbs over 150 gr. daily

(C) Dec. 2011 3rd NMR after another 7 more months thinking Doc’s advice is worthwhile I added in yet more fat (mainly daily 2 tablespoons of coconut oil, more 90% chocolate), bumped Niacin up to 1,000 mg twice a day (2,000 mg. total daily), cut out the Amazake, kept up the vitamin D adding daily vitamin K & daily ate main mid-day meal out as lunch on spicy Thai & Chinese fish/shrimp/soup/rice meals (my next control):
*** LDL # P ………. = 764 nmol/L ————— being LDL C of 107 mg/dL ( 2x coconut’s saturated fat)
***small LDL # P… = less than 90 nmol/L ——–surprised me NMR can’t count lower
***HDL # P ……… = 41.4 umol/L ——————– being an increase to HDL C of 88 mg/dL
*** Triglycerides ….= 43 mg/dL ——————- daily carbs below ~ 120 gr. & lost too much weight

Isn't that great? Spectacular job, Might!

MIght achieved values that are superior to that achievable with, say, a high-dose statin strategy. Statins only reduce total LDL particles, reducing small LDL in a non-selective way. And, of course, this diet does not cause muscle aches, memory loss, nor liver problems.

Something to consider: As the diet has become so effective, we can reduce our reliance on niacin. In fact, the benefits of niacin diminish substantially, as small LDL is reduced, HDL increased, triglycerides decreased, and postprandial lipoproteins subdued with the diet only.

Low-carb is heart healthy

4. January 2012 William Davis (88)
Anybody following the discussions in these pages know that: Limiting carbohydrate intake reduces risk for coronary heart disease and heart attack.

First of all, why do conventional diets advocate restricting saturated and total fat? From the standpoint of surrogate markers of cardiovascular risk, cutting saturated and total fat reduces total cholesterol; reduces calculated LDL cholesterol; and may reduce c-reactive protein modestly (an index of inflammation). It also increases blood sugar and HbA1c (reflecting the prior 60 days blood sugars), increases glycation of the proteins of the body leading to cataracts, arthritis, and hypertension.

Problem: Total cholesterol is a combination of HDL cholesterol, an estimate of VLDL cholesterol (triglycerides), and LDL cholesterol. It is a composite of both "good" things (HDL) and "bad" things (LDL and VLDL). Cutting saturated and total fat results in reduced HDL, increased VLDL/triglycerides, and a reduction in calculated LDL. Pretty weak stuff. The last item, i.e., reduction in calculated LDL, is not even a real phenomenon. In fact, the net effect in most genotypes (genetic types) may be negative: increased heart disease risk.

In contrast, what is the effect of reducing carbohydrate without restricting fat? (In the approach I use, we start with elimination of the most destructive of carbohydrates, wheat, followed by reducing exposure to other carbohydrates, especially cornstarch and corn products, sugar, and oats.) If, say, we cut carbohydrate intake into the range of a truly low-carbohydrate diet of 10-15 grams per meal ("net" carbs, or total carbohydrates minus fiber), then we witness a number of metabolic transformations:

Reduced fasting triglycerides and VLDL
Reduced postprandial (after-eating) triglycerides, chylomicrons, and chylomicron remnants
Increased HDL and shift towards large HDL particles (presumably more protective)
Reduced small LDL particles
Reduced glycation and oxidation of small LDL particles
Reduced hemoglobin A1c
Reduced c-reactive protein and other inflammatory markers
Reduced blood pressure

By slashing carbohydrates, we also witness weight loss from visceral fat, reversal of pre-diabetes and diabetes, and reduced phenomena of glycation. And, if the wheat-free part of low-carb is maintained, you can also see marked improvement in gastrointestinal health, relief from joint pains, relief from leg edema, relief from migraine headaches, improved behavior and ability to concentrate in children with impaired learning, ADHD, and autism, better mood, deeper sleep. You will see multiple inflammatory and autoimmune diseases improve or completely relieved, such as rheumatoid arthritis and ulcerative colitis.

Having personally gone down the diabetic path and back by cutting the fat in my diet, now maintaining a HbA1c of 4.8% with fasting glucose 84 mg/d; (without medications), there should be no remaining doubt: Low-carb diets, especially if wheat-free, dramatically reduce the factors leading to heart disease; low-fat diets worsen the factors leading to heart disease.

Mocha Walnut Brownies

1. January 2012 William Davis (11)
Richer than a cookie, heavier than a muffin, brownies are ordinarily an indulgence that leaves you ashamed of your lack of restraint. Have one . .  . or two or three, and you will surely pack on a pound of belly fat.

But these mocha walnut brownies, as with other recipes I provide, will not pack on the pounds. With no wheat to trigger appetite, nor any readily-digestible carbohydrate to generate blood sugar highs and lows, you can have a nice brownie or two or three and nothing bad happens: You don’t send blood sugar sky-high, don’t trigger formation of small LDL particles and triglycerides, you don’t trigger appetite, you don’t gain a pound of belly fat. You simply have your brownie(s) and enjoy them.

Serve these brownies plain or topped with cream cheese, natural peanut or almond butter, or dipped in coffee.


Ingredients:
8 ounces unsweetened baking chocolate (100% chocolate)
4 tablespoons coconut oil or butter, melted
2 large eggs, separated
½ cup coconut milk (or sour cream)
2 teaspoons vanilla extract
2 cups ground almonds
2 tablespoons coconut flour
1 cup chopped walnuts
¼ cup unsweetened cocoa powder
2 teaspoons instant espresso
Sweetener equivalent to 1 cup sugar or to taste (e.g., liquid stevia, Truvía, erythritol)


Preheat oven to 350º F.

Melt chocolate using double boiler method or in 15-second increments in microwave. Stir in melted coconut oil or butter.

In small bowl, beat egg whites until frothy. Add egg whites, egg yolks, coconut milk, and vanilla extract to chocolate mixture and mix thoroughly by hand.

In separate bowl, combine ground almonds, coconut flour, walnuts, cocoa powder, espresso, and sweetener. Mix thoroughly.

Add dry mix to chocolate mix and mix together thoroughly. If dough is too stiff, add additional coconut milk, one tablespoon at a time.

Place mixture in 9-inch baking pan and bake for 25 -30 minutes or until toothpick withdraws dry.

Are you hungry?

6. December 2011 William Davis (43)
Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

 

Chocolate . . . for adults only

30. November 2011 William Davis (22)
If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.
I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

19. November 2011 William Davis (29)
At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

14. November 2011 William Davis (73)
More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Blood sugar lessons from a Type I diabetic

23. July 2008 William Davis (15)
A friend of mine is a Type I, or childhood onset, diabetic. He's had it for nearly 50 years, since age 6. He's also in the health industry and is a good observer of detail.

He made the following interesting comments to me recently when talking about the effects of various foods on blood sugar:

"When I eat normally, like some vegetables or salad and meat, I dose up to 10 units of insulin to control my blood sugar.

"If I eat a turkey sandwich on two slices of whole wheat, I usually dose 15 units. The bread makes my blood sugar go to 300 if I don't.

"If I eat a Cousins's Sub [a local submarine sandwich chain], I dose 15 units. The bread really makes my blood sugar go up.

"I can only eat a Quarter Pound from McDonald's once a year, because it make my blood sugar go nuts. I dose 15-20 units before having it, and I feel like crap for two days afterwards.

"If I eat Mexican food, I have to dose 15-20 units. For some reason, it's gotten worse over the years, and I need to dose higher and higher.

"Chinese food is the absolute worst. I dose 20-25 units before eating Chinese. I'll often have to dose more afterwards, because my blood sugar goes so berserk."


Nothing beats the real-world observations on the impact of various foods on blood sugar than the observations of people with Type I diabetes. All the insulin they get is in a syringe. Dosing needs to match intake.

Personally, though I love the taste of Americanized Chinese food, I've always been suspicious of what exactly goes into these dishes. But I was unaware of the blood sugar implications.

The impact of Mexican I believe can be attributed to the cornstarch used in the tacos and tortillas, though I also wonder if there are other starches being snuck in, as well.

Lessons about omega-3s from Japan

23. July 2008 William Davis (7)

Japan provides a useful "laboratory" for studying the effect of a culture that relies heavily on eating fish.

The JELIS Trial, the topic of a previous Heart Scan Blog post, showed that supplementation with the single omega-3 fatty acid, EPA, 1800 mg per day (the equivalent of 10 capsules of 'standard' fish oil that contains 180 mg per day of EPA, 120 mg of DHA) significantly reduced heart attack in a Japanese population. Interestingly, this benefit was additive to the already substantial intake of omega-3 fatty acids among the general Japanese population, a population with a fraction of the heart attacks found in western populations like the U.S. (approximately 3% over 5 years in Japanese compared to several-fold higher in a comparable American group).

While there may be genetic and other cultural and lifestyle reasons behind the dramatically reduced cardiovascular risk in Japanese, it is undeniably at least partially due to the increased intake of omega-3 fatty acids from fish. Incidentally, the purported benefits of omega-3 fatty acids provide a vigorous counter-argument to the idea that all humans should be vegetarians.

Anyway, if we were to take some lessons from the Japanese and their greater habitual intake of omega-3 fatty acids from fish, they might include:

--Rural and coastal Japanese are the sub-populations with the highest reliance on fish, about a quarter-pound a day. (Gives new meaning to the idea of a "Quarter Pounder," doesn't it?) This is at least five-times greater than the intake of an average American.

--Likewise, the blood level of omega-3s in the blood of Japanese is 5-fold higher than in Americans.

--The average intake of omega-3s (EPA + DHA) among a broadly-selected population of Japanese is 850 mg per day (320 mg EPA; 520 mg DHA). Intake ranges from 300 mg per day all the way up to 3100 mg per day.

--Greater omega-3 intake (EPA + DHA) is associated with lesser carotid intimal-medial thickness, an index of body-wide atherosclerosis.

--Japanese have far less heart attack and stroke despite greater prevalence of smoking (nearly half of Japanese) and drinking.

--Total fat intake (percent of calories) is nearly identical between Americans and Japanese. It's the proportion of fat calories from omega-3 that is greater, the proportion of omega-6 that is less in Japanese.


The Japanese eat their fish in ways that we do not: As sashimi (raw, as with sushi in its various forms like Nigiri and Chirashi); fried in tempura; shaved, dried fish sprinkled on about anything you can imagine (it's not as bad as it sounds); as a snack, as in dried cuttlefish (which you can purchase in packages as a portable, sweetened fish that you eat on-the-run--I know it sounds awful, but don't poke fun at it until you've tried it); in "soups" with soba noodles. Fish is commonly consumed with rice and soy sauce, as well as other soy-based foods, such as tofu, miso (soy bean paste), or natto. 


I believe that there are some lessons to take from the Japanese and their fish-consuming habits:

1) An omega-3 fatty acid intake of at least 1000 mg per day yields measurable cardiovascular benefits. 

2) Despite the fears over mercury and pesticide residues in fish, this seems to not have played out to be a real-life effect in the Japanese, who consume five-fold greater quantities of fish. 

3) My mother was right after all when she encouraged us to eat more fish. 


DIRECT Study result: Low-carb, Mediterranean diets win weight-loss battle

19. July 2008 William Davis (14)
Drs. Iris Shai and colleagues released results of a new Israeli study, the Dietary Intervention Randomized Controlled Trial (DIRECT) Trial, that compared three different diet strategies. Of those tested, a low-carbohydrate diet was most successful at achieving weight loss.

You can find the full-text of the study on the New England Journal of Medicine website.

322 participants followed one of three diets over two year period. Compared head-to-head, the (mean) weight loss in each group was:

• 2.9 kg (6.4 lbs) for the low-fat group
• 4.4 kg (9.7 lbs) for the Mediterranean-diet group
• 4.7 kg (10.3 lbs) for the low-carbohydrate group

(Average age 52 years at start; average body-mass index, or BMI, 31.)

The conclusion was that the low-carb diet performed the best, with 60% greater weight loss, with the Mediterranean diet a close second.


The diets

The low-fat diet was based on the American Heart Association diet, with 30% of calories from fat (10% from saturated fat) and food choices weighted towards low-fat grains, vegetables, fruits, and legumes and limited additional fats, sweets, and high-fat snacks; calorie intake of 1500 kcal per day for women and 1800 kcal per day for men was encouraged.

The Mediterranean diet was a moderate-fat diet rich in vegetables, with reduced red meat, and poultry and fish replacing beef and lamb. Total calories from fat of 35% per day or less was the goal, with most fat calories from olive oil and a handful of nuts. Like the low-fat program, calories were limited to 1500 kcal per day for women, 1800 kcal per day for men.

The low-carbohydrate diet was patterned after the popular Atkins’ program, with 8% participants achieving the ketosis that Dr. Atkins’ advocated as evidence that a fat-burning metabolism was activated, rather than sugar-burning as fuel. For the 2-month “induction phase,” 20 grams of carbohydrates per day was set as the goal, followed by 120 grams per day once the weight goal was achieved. Unlike the other two diets, calories, protein and fat were unlimited.


Weight loss, lipids, inflammation

You can see from the weight loss graph that the low-carb approach exerted the most dramatic initial weight loss. Interestingly, much of the weight-loss benefit was lost as the carbohydrate intake increased, by study design, back to 120 mg per day. However, the other two diet approaches showed similar phenomena of “giving back” some of the initial weight loss.

The low-carbohydrate diet exerted the greatest change in cholesterol, or lipid, panels: increased HDL 8.4 mg/dl vs. 6.3 mg/dl on low-fat; the triglyceride response was the most dramatic, with a reduction of 23.7 mg/dl vs. 3.7 mg/dl on low-fat. Interestingly, the LDL cholesterol-reducing effect of all three diets was modest, with the most reduction achieved by the Mediteranean diet.

The inflammatory measure, C-reactive protein (CRP), was reduced most effectively by the low-carb and Mediterranean diets, least by the low-fat diet. HbA1c, a measure of long-term blood sugar, dropped significantly more on the low-carb diet.

When the final dietary composition was examined, interestingly, there really were only modest differences among the three diets, with 8% less calories from carbs, 8% greater calories from fat, comparing low-carb to low-fat, with Mediterranean intermediate.



Taken at face value, this useful exercise quite clearly shows that, from the perspective of weight loss and correction of metabolic parameters like triglycerides, HDL,CRP, and blood sugar, low-carbohydrate wins hands down, with Mediterranean diet a close second.

It also suggests that a return to a carbohydrate intake of 120 mg/day allows a partial return of initial weight lost, as well as deterioration of metabolic parameters after the initial positive changes.

Although the study has already received some criticism for such potential flaws as the modest number of Atkins’ followers achieving ketosis (8%), suggesting lax adherence, and the reintroduction of the 120 mg/day carbohydrate advice, I can suspect that these may have been compromises drawn to satisfy some Institutional Review Board. (Whenever a study is going to be conducted involving human subjects, a study needs to pass through the review of an Institutional Review Board, or IRB. IRB’s, while charged to protect human subjects from experimental abuses, also tend to be painfully conservative and will block a study or demand changes even if they are not dangerous, but just veer too far off the mainstream.)


However, several unanswered questions remain:

1) How would the diets have compared if the carbohydrate restriction were continued for a longer period, or even indefinitely? (The divergences would likely have been dramatic.)
2) Will low-carb exert the same cardiovascular event reduction that the Mediterranean approach has shown in the Lyon study and others?
3) Are there effects on health outside of the measures followed that differ among the three diets, such as cancer? (I doubt it, especially given the modest real differences over time. But this will be the objection raised by various "official" organizations.)


I would further propose that:

Low-fat diets are dead

The AHA will cling to their version of low-fat diet, based on difficulty in changing course for any large, consensus-driven organization, not to mention the substantial ($100’s of millions) revenues derived from endorsing low-fat manufactured products. The AHA will also point to the lack of difference in LDL cholesterol among the three, since they cannot get beyond the fact that there’s more to coronary risk—a lot more—than LDL.


Off-the-shelf diets achieve off-the-shelf results

If you just need a T-shirt, a medium might fit fine. But if you’d like a nicely fitting suit or dress, then tailoring to your individual proportions is needed. When aiming towards maximizing benefits on lipoproteins and coronary risk, none of these diets achieve the kinds of changes we often need for coronary plaque reversal, as in the Track Your Plaque program. That requires making dietary changes that exert maximal effects on lipoprotein patterns.

Do I sell heart scans?

18. July 2008 William Davis (12)
I came across a criticism of the Track Your Plaque program recently that suggested that it was nothing more than a program to sell CT heart scans.

Huh?

I suppose if you say that the Track Your Plaque program is nothing more than a way to sell heart disease prevention, omega-3 fatty acids from fish oil, vitamin D, better nutrition, and better identification of causes of heart disease . . . well, I believe that would be true.

But is the program a "front" to sell heart scans?

No, it is not, nor has it ever been.

I've heard about these peculiar suspicions about the program before. Though I've never taken them seriously, let me clear up any lingering uncertainty:


--I have no relationship with any heart scan center, scanning facility, or hospital other than to interpret heart scans.

I do not own a scanner, I have no financial interest in a scanner or scanning center, nor have I ever had any interest. I also have no plans to do so in the future. Let business people in the imaging business do that. I want no part of it. I have seen what these people go through and, frankly, I want no part of it, nor do I want the appearance that I am advocating scans to make money. I'm accused of trying to make money from scans even when I do not have any financial interest!


--I do not sell heart scans or imaging packages, nor have I ever done so.

You can't buy a scan through Track Your Plaque, The Heart Scan Blog, or through me. To me, heart scans are simply a measuring tool to identify the extent of coronary plaque, as well as a tracking tool to follow its course. Without it, there would be no Track Your Plaque. But there is also no alternative. The closest alternative would be carotid intimal-medial thickness, a technique, while useful, is a distant second choice to indirectly gauge coronary plaque by examining the thickness of the carotid lining (not carotid plaque). Perhaps in 10 years, a better measure to gauge and track coronary plaque will emerge that has superior aspects over CT heart scanning. If reasonable, safe, accessible, and quantitative, then Track Your Plaque may adopt that technology as its measuring tool.

Track Your Plaque is not about heart scanning; Track Your Plaque is about measuring and tracking plaque that, in 2008, is still best accomplished with CT heart scans.


--I make loads of money from heart scans and Track Your Plaque.

Yeah, right.

Track Your Plaque is a volunteer venture for my team; none of us get paid a penny for doing all we do, including me. We charge a membership fee on the website (somewhere around $6-7 a month) to pay our expenses, such as code writing for our proprietary software (much of it remains under development), printing costs, modest legal costs, the costs of doing business (e.g., accountant). Despite the fact that Track Your Plaque and the Heart Scan Blog occupies a substantial part of the day of the Track Your Plaque team, none of us are reimbursed for our time. I do believe, however, that this concept is so enormously powerful that it will, someday, pay us all enough to allow us to devote more time and effort to it.

Personally, I can't wait to devote more time and effort to this concept that is simple, logical, and effective. More research is needed, more development is needed, more discussion is needed. Right now, it is all accomplished outside of our busy schedules, including my full-time cardiology practice. I continue to have 7 am procedures, middle-of-the-night calls, weekend hospital rounds and emergencies (though virtually none of these are the patients involved in prevention, but the "other" people: atrial fibrillation, elderly heart failure patients, rhythm disorders, cardiomyopathies, pulmonary hypertension, peripheral vascular disease, the non-compliant).


--The book, Track Your Plaque, is a gimmick to sell you a heart scan.

No, it's a program that relies on this technology. But there's no special deal, no discounts, no steering to heart scan centers that I have a special arrangement with. No such thing exists, nor has there ever been such an arrangement.


I've heard it all. Early on, when I was helping my friend, Steve Burlingame and his wife, Nancy, set up Milwaukee Heart Scan, I helped by providing medical oversite, education of physicians and public, and interpreting heart scans. After all, in the "early days," nobody knew anything about heart scans. It was a long, hard climb against ignorance, habit, entrenched thinking, stubbornness, and stupidity. I've been paid next to nothing for all this. I told Steve long ago that, given the extraordinary expenses of maintaining an independent scanning center, that he should first pay his expenses, pay his technologists, receptionists, and nurse, pay himself, then pay me for reading scans if he had any money left over. Most of the time, Steve had nothing left over and I was paid nothing.

So, while some of my colleagues were assuming that I was rolling in money from "promoting" heart scans, the reality was that I was doing nearly everything for free. (It certainly wasn't the high life I was living; I don't drive a Mercedes, take fancy vacations, none of that. In fact, I work about 51 weeks a year.)

Why do I do this if it doesn't yield a big flow of money? Because I believe in it as a superior path to the conventional. If I were simply interested in making more money--I wouldn't do it. I would simply do what all my cardiology colleagues are doing: more heart catheterizations, more angioplasties and stents, learning how to do carotid stents, iliac stents, peripheral angioplasty, renal stents, acquiring the skills to put in defibrillators, new device insertion like umbrellas in the interatrial septum, etc. There's plenty more money in that. It's also not that hard. I know, because that is my background: high-risk cardiac interventions. That's what I was trained to do, that's what I did from a number years, until I started to see that this was nothing more than "putting out fires" in people who became increasingly ill and reliant on bail-out procedures. It makes lots of money, but it is also fundamentally wrong.

So, no, I do not sell heart scans, nor is the Track Your Plaque program or The Heart Scan Blog meant to promote heart scans except as a tool for tracking this disease.

That's it, pure and simple.

Plaque is the new cholesterol

17. July 2008 William Davis (3)
Which is more important: cholesterol or coronary plaque?

Ask what Dr. Michael Eades' calls "statinators," and you will likely receive a befuddled look. Or, you might receive comments like "Measuring plaque has never been shown to reduce mortality."

While risk factors for heart disease are important, no doubt (my office practice is about half lipid consultation and complex hyperlipidemia management), for many they have become an end in themselves. In other words, LDL cholesterol in particular dominates thinking so much that it has caused many to exclude the fact that plaque---coronary atherosclerotic plaque---is the disease itself.

Dozens of studies, from the St. Francis Heart Study to the 25,000-participant UCLA registry, to the recently-released MESA database (ethic differences, women, as well as superiority to carotid measures) have repeatedly shown that heart scan scores (coronary artery calcium scores) are superior to conventional risk factors (usually via the Framingham risk score) for predicting future heart attack and other events. And the differences are not minor incremental differences. The predictive power of plaque measurement via heart scanning is multiples better: 4 times, 10 times, 20 times or more in various subgroups.

Much of what we do in medicine is not based on long-term studies of outcome, pitting some diagnostic measure or treatment against placebo. It is already standard practice to measure plaque via heart catheterization, crudely via stress testing, and increasingly popular CT coronary angiography. None of these methods have been subjected to studies comparing testing vs. not testing in a large population, followed by some program of prevention to assess differences in mortality, heart attack, and other events.

Why should heart scan be held to such a standard?

Dr. Scott Grundy, lipid guru and one of the experts who sat on the Adult Treatment Panel-II for lipid management guidelines, recently stated [emphasis added]:

"Imaging has at least 3 virtues. It individualizes risk assessment beyond use of age, which is a less reliable surrogate for atherosclerosis burden; it provides an integrated assessment of the lifetime exposure to risk factors; and it identifies individuals who are susceptible to developing atherosclerosis beyond established risk factors. Also of importance, in the absence of detectable atherosclerosis, short-term risk appears to be very low."

Well said, and from a vocal statinator, to boot.

Sadly, Dr. Grundy goes on to say how plaque imaging can serve to better determine who will benefit from statin drug use.

Of course, you and I know that there is far more to reduction of cardiovascular risk applied to a framework of serial plaque quantification ("tracking plaque"!) than statin drugs. I doubt that a man as intelligent as Dr. Grundy truly believes this. I suspect that he is simply stating what he knows what will be published without resistance in the standard medical literature, trying to achieve a modest incremental success just by raising consciousness about heart scanning and plaque imaging: first things first.

Maybe next will be a plaque-tracking, or even a plaque-reducing, mainstream conversation, just like the one we've been conducting for the past four years.

Track Your Plaque success story blows it

17. July 2008 William Davis (3)
Joe was a Track Your Plaque Success Story. With a starting heart scan score of 278, he dropped it 12 months later to 264, a 5% reduction. Though not a huge reduction, Joe's risk for a heart attack or other coronary event was virtually zero. I was very proud of Joe.

Among the culprit lipoprotein patterns that caused Joe's plaque was lipoprotein(a), or Lp(a). Niacin was therefore crucial to his program. It was among the principal reasons he dropped his heart scan score and reduced his risk for heart attack so dramatically.

Since he retired, Joe has been freewheeling around the country, traveling and having a great time. He consequently stopped thinking about his heart disease and Lp(a). He also tired of the occasional hot flushes he'd experienced with niacin. Though the flushes were promptly aborted by drinking two glasses of water, he simply didn't want to be bothered.

So when Joe saw this interesting and tantalizing "flush-free niacin" on the store shelf, he grabbed it.

Joe came back to the office. His blood pressure was 190/94, so high that he was having occasional chest pains from it (which can happen when something called "left ventricular diastolic dysfunction" develops from hypertension). His lipoprotein patterns were terrible, including a big upward jump in Lp(a) and drop in HDL. So I asked him to have another heart scan right away: Score 371, a 40% increase. In other words, his program went down the toilet.

Why?

Simple: Flush-free niacin. I've said it before (No flush = No effect and No flush niacin kills) and I'll say it again:

Flush-free or No-flush niacin is a complete, unadulterated, completely ineffective SCAM.

Flush-free or no-flush niacin is not a substitute for niacin. Joe is yet another example of how dangerous this scam can be. It turned one of our great success stories into a failure.

Please, please, please do not fall for this misleading and potentially dangerous scam product. While the product itself is not intrinsically dangerous, it denies you the benefits of the real thing: niacin.

Thankfully, the mistake in Joe's program was caught before a heart attack or other catastrophe. He did manage to pass a stress test, though with a flagrantly out-of-control blood pressure response. We'll get him back on track--but with niacin, the real thing.

Dr. Cannell comments on vitamin D lab tests

14. July 2008 William Davis (9)
As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D.

Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here.

(I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.)


Does it matter what reference lab my doctor uses?

Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."

Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.

Demand for vitamin D tests soars as nutrient's potential benefits touted.

Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.



My doctor prescribed Drisdol, 50,000 IU per week. What is it?

Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.



What is the ideal level of 25(OH)D?

We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

I have advanced renal failure and I'm on dialysis, how much vitamin D should I take?

The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases.

When I asked my doctor for a 25(OH)D blood test, he just laughed and said it was all idiotic. What can I do?

Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.

Privileged information

12. July 2008 William Davis (9)
In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit.

Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights.

But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.

Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly.

Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.

And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies.

Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few.

Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled.

Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets.

I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people.

Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.

But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on.

Dr. Jeffrey Dach on the Track Your Plaque program

10. July 2008 William Davis (5)
Dr. Jeffrey Dach posted a great piece on his blog, Bioidentical Hormone Blog , about his perspective on the Track Your Plaque program.

It's worth reading even for those familiar with the program, just to see a slightly different perspective. He also included many great graphics to illustrate his points.

Vitamin D and programmed aging?

9. July 2008 William Davis (8)
As we age, we lose the capacity to activate vitamin D in the skin.

Studies suggest that, between ages 20 and 70, there is a 75% reduction in the ability to activate vitamin D. The capacity of conversion from 25 (OH) vitamin D to 1,25 di(OH) vitamin D also diminishes.

Holick M. Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease.



From Holick, M. 2006

This would explain why 70-year olds come to the office, just back from the Caribbean sporting dark brown tans, are still deficient, often severely, in blood levels of vitamin D (25(OH) vitamin D). A tan does not equal vitamin D.














Courtesy Ipanemic


A practical way of looking at it is that anyone 40 years old or older has lost the majority of ability for vitamin D activation.

This often makes me wonder if the loss of vitamin D activating potential is nature's way to get rid of us. After all, after 40, we've pretty much had our opportunity to recreate and make our contribution to the species (at least in a primitive world in which humans evolved): we've exhausted our reproductive usefulness to the species.

Is the programmed decline of vitamin D skin activation a way to ensure that we develop diseases of senescence (aging)? The list of potential consequences of vitamin D deficiency includes: osteoporosis, poor balance and coordination, falls and fractures; cancer of the breast, bladder, colon, prostate, and blood; reductions in HDL, increases in triglycerides; increased inflammation (C-reactive protein, CRP); declining memory and mentation; coronary heart disease.

Isn't that also pretty much a list that describes aging?

A fascinating argument in support of this idea came from study from St Thomas’ Hospital and the London School of Medicine:

Higher serum vitamin D concentrations are associated with longer leukocyte telomere length in women

Telomeres are the "tails" of DNA that were formerly thought to be mistakes, just coding for nonsense. But more recent thinking has proposed that telomeres may provide a counting mechanism that shortens with aging and accelerates with stress and illness. This study suggests that both vitamin D and inflammation (CRP) impact telomere length: the lower the vitamin D, the shorter the telomere length, particularly when inflammation is greater.
















Data supporting vitamin D's effects on preventing or treating cancer, osteoporosis, lipid abnormalities, inflammation, cardiovascular disease, etc., is developing rapidly.

Now the big question: If declining vitamin D is nature's way of ensuring our decline and death, does maintaining higher vitamin D also maintain youthfulness?

I don't have an answer, but it's a really intriguing idea.

Tell me your wheat elimination story and receive a copy of my new book, Wheat Belly

6. May 2011 William Davis (68)
I'm looking for interesting wheat-free experiences.

For the past year, I have been writing my new book, Wheat Belly . After many, many late nights and soccer games missed, it's now finished. The book will be out in fall, 2011, to be published by Rodale, the Prevention Magazine people.

Wheat Belly will provide, in excruciating detail, the discussion of how wheat was transformed from innocent wild grass to incredible genetically-altered Frankengrain and why it has become such a health nuisance.

I am looking for interesting stories of wheat elimination for the online and special editions of the book. If you have an interesting tale of wheat-elimination successes, woes, or drama, I'd like to hear about it. Even better, if you would agree to be interviewed by phone (not for live use, just for comments and detail), the editors at Rodale will help tell your story.

If we use your story, I will have a free copy of the new Wheat Belly sent to you when it becomes available.

Please post your story in the comments here. I will then need to obtain your contact info, which we will do privately.

 

Real men don't eat carbs

27. April 2011 William Davis (0)
Real men don't eat carbs. At least they don't eat them without eventually paying the price.

How do carbohydrates, especially those contained in "healthy whole grains," impair maleness? Several ways:

--Consume carbohydrates, especially the exceptional glucose-increasing amylopectin A from wheat, and visceral fat grows. Visceral fat increases estrogen levels; estrogen, in effect, opposes the masculinizing effects of testosterone. Overweight males typically have low testosterone and high estrogen, a cause for depression, emotionality, weight gain, and low libido.

--Sugar-provoking carbohydrates like wheat cause visceral fat to accumulate which, in turn, triggers prolactin to be released. Increased prolactin in a male causes growth of breasts: "man boobs,""man cans," "moobs," etc. This is why male breast reduction surgery is booming at double-digit growth rates. In cities like LA, you can see billboards advertising male breast reduction surgery.

--Carbohydrates increase visceral fat that sets the stage for postprandial abnormalities, i.e., markedly increased and persistent lipoproteins, like chylomicron remnants and VLDL particles, that impair endothelial function literally within minutes to hours of ingestion. Impaired endothelial function underlies erectile dysfunction. This is why Internet spammers so enthusiastically send you offers for discounted Viagra.

--Carbohydrates increase blood sugar which provokes the process of glycation, glucose modification of proteins, that also contributes to endothelial dysfunction followed by erectile dysfunction.

Real men therefore avoid carbs.

Overweight males typically have low testosterone, high estrogen, a cause for depressions, emotionality, and weight gain.

--Consume carbohydrates like wheat and visceral fat causes prolactin to be released. Increased prolactin in a male causes growth of breasts: "man boobs,""man cans," "moobs," etc. This is why male breast reduction surgery is booming at double-digit growth rates. In cities like LA, you can see billboards advertising male breast reduction surgery.

--Carbohydrates increase visceral fat that sets the stage for postprandial abnormalities, i.e., markedly increased and prolonged lipoproteins like chylomicron remnants and VLDL particles that impair endothelial function. Impaired endothelial function underlies erectile dysfunction. Eat a bagel, become impotent.

Why do the Japanese have less heart disease?

24. April 2011 William Davis (49)
We should look to the Japanese to teach us a few lessons about preventing heart disease. A Japanese male has only 65% of the risk of an American male (despite 40% of Japanese men being smokers), while a Japanese woman has 80% less risk than an American woman. While the U.S. is near the top of the list of nations with highest cardiovascular risk, Japan is the lowest.

What are they doing right?

There is no one explanation, but several. Genetics probably does not play a substantial role, by the way, as demonstrated by observations of Japanese people who emigrate to Western cultures. People of Japanese heritage living in Hawaii, for instance, develop the same cardiovascular risk as non-Japanese living in Hawaii. They also develop obesity and diabetes.

Among the factors that likely contribute to reduced risk in Japanese people:

--A style of eating that does not include a lot of sweet foods. No breakfast cereal or donuts for breakfast, for instance, but miso soup with tofu, fish, green onions, and daikon (as takuan, or pickled radish).
--Seaweed--It's probably a combination of the green phytonutrients and iodine. Typical daily iodine intake is in the neighborhood of 5000 mcg per day from nori, kombu, wakame, and other seaweed forms. (The average American obtains 125 mcg per day of iodine from diet.)
--Seafood--Fish in many forms not seen in the U.S. are popular.
--Green tea--Consumption of green tea has been confidently linked to reduced cardiovascular risk, probably via visceral fat-reducing, anti-oxidative, and anti-inflammatory effects. Although tea in Japan is often the less flavonoid-rich oolong tea, softer benefits from this form are likely.
--Soy--Tofu, miso, and soy sauce are staples. It's not clear to me whether soy is intrinsically beneficial or whether it is beneficial because it serves to replace unhealthy alternatives. (Genetic modification may change this effect.)
--Reduced exposure to cooked animal products (except seafood). This is not a saturated fat issue, but probably an advanced glycation end-product/lipoxidation issue that result from cooking.
--The lack of a "eat more healthy whole grain" mentality, the advice that has plunged the entire U.S. into the depths of a diabetes and obesity crisis (along with high-fructose corn syrup and sugar). Noodles like udon and ramen do have a place in their diet, as do some dessert foods. But the overall wheat exposure is less--no bagels, sandwiches, and breakfast cereals.
--Less overweight and obesity--The above eating style leads to less weight gain.

Japanese foods have a unique taste, consistency, and mouth-feel that go well with saltiness, thus the downside of their diet: salt consumption. On a broad scale, high salt consumption has been associated with hypertension and gastric cancer. But the tradeoff has, on the whole, been a favorable one.


One study trying to find some answers:

Dietary patterns and cardiovascular disease mortality in Japan: a prospective cohort study.

Shimazu T, Kuriyama S, Hozawa A et al.
Division of Epidemiology, Department of Public Health and Forensic Medicine, Tohoku University Graduate School of Medicine, Japan.


We prospectively assessed the association between dietary patterns among the Japanese and CVD mortality. Dietary information was collected from 40 547 Japanese men and women aged 40-79 years without a history of diabetes, stroke, myocardial infarction or cancer at the baseline in 1994.
During 7 years of follow-up, 801 participants died of CVD.

Factor analysis (principal component) based on a validated food frequency questionnaire identified three dietary patterns: (i) a Japanese dietary pattern highly correlated with soybean products, fish, seaweeds, vegetables, fruits and green tea, (ii) an 'animal food' dietary pattern and (iii) a high-dairy, high-fruit-and-vegetable, low-alcohol (DFA) dietary pattern. The Japanese dietary pattern was related to high sodium intake and high prevalence of hypertension. After adjustment for potential confounders, the Japanese dietary pattern score was associated with a lower risk of CVD mortality (hazard ratio of the highest quartile vs the lowest, 0.73; 95% confidence interval: 0.59-0.90; P for trend = 0.003). The 'animal food' dietary pattern was associated with an increased risk of CVD, but the DFA dietary pattern was not.

The Japanese dietary pattern was associated with a decreased risk of CVD mortality, despite its relation to sodium intake and hypertension.

Niacin: What forms are safe?

20. April 2011 William Davis (52)
Niacin, or vitamin B3, remains a confusing issue for many people. It shouldn't be.

It doesn't help that most physicians and many pharmacists also do not understand the basic issues surrounding niacin. The only reason why there is any level of prevailing knowledge about niacin is that Kos Pharmaceuticals managed to "pharmaceuticalize" a niacin preparation, prescription Niaspan, that provided the revenue to fund professional "education."

Niacin can be helpful to increase HDL, reduce small LDL particles and shift them towards the more benign large particles, reduce triglycerides, and reduce lipoprotein(a).

So here's a brief description of the various forms that you will find niacin:

Immediate-release niacin--Also called crystalline niacin or just niacin. This is the original niacin that releases within minutes of ingestion. Because it releases rapidly, it triggers the most intense "hot flush." While this form of niacin works wonderfully well, is the safest, and is dirt cheap, the majority of people are simply unable to tolerate the intense flush. It also works best taken twice a day, generating two intolerable flushes per day.

Slow-release niacin--These preparations were popular in the 1980s, since the slow 12 to 24 hour pattern of release minimized the annoying hot flush. But, with prolonged use, it also became apparent that an unnaceptable frequency of liver toxicity developed. Unfortunately, this means that any niacin preparation that trickles niacin out over an extended period, including many of the slow-release preparations now sold in health food stores and pharmacies, have potential for liver toxicity. These preparations should be avoided.

6-hour release niacin--Releasing niacin more slowly than immediate-release niacin but more rapidly than slow-release niacin, 6-hour release (or what the Niaspan people call "extended-release" niacin) is nearly as effective as immediate-release niacin with approximately the same low potential for liver toxicity. It is far less liver toxic than slow-release niacin. 6-hour release niacin therefore offers the best balance between effectiveness and safety. Preparations that show this pattern of release include Niaspan ($180 per month), the poorly-named Sloniacin (about $8 per month), and Enduracin (about $7 per month) for 1000 mg per day. (Some Track Your Plaque Members have also determined that several other over-the-counter preparations have been demonstrated to share a similar pattern of release.)

Then there are the scam products that have no useful effect at all:

Flush-free or no-flush niacin--Inositol hexaniacinate, or 6 niacin molecules bound to the sugar, inositol, has no effect in humans, at least not with the dozen or so preparations that I've seen used. Nor are there any data to document the effectiveness of flush-free niacin. It's also more expensive.

Nicotinamide--This niacin derivative likewise has no effect on the usual targets for niacin treatment.

While I used to prescribe Niaspan, the ridiculous pricing and aggressive marketing really turned me off. I now advise my patients and our online followers to use only Sloniacin or Enduracin, unless you can tolerate immediate-release niacin.

Introduction to the New Track Your Plaque book, version 2.0

18. April 2011 William Davis (0)

Out with the old,
in with the new  



“I believe that you are suffering from what is called a fatty degeneration of the heart.”

Dr. Tertius Lydgate to Mr. Casaubon on making a diagnosis with the new medical device, the stethoscope.

George Elliot
Middlemarch, 1871





Old notions in medicine have a peculiar way of lingering.

In 1882, Dr. Robert Koch discovered the tubercle bacillus in tissues of people with “consumption.” By connecting a bacterium with the disease, he usurped the long held notion that tuberculosis was a degenerative disease caused by lack of fresh air. But, for decades after Dr. Koch’s revelation, the “bad air” belief persisted. Surgical collapse of the lung, a painful and barbaric treatment for tuberculosis, persisted well into the 1960s, years after effective antibiotics were discovered in 1947.

The medical community of the 19th century viewed mental illness as the hereditary end-product of ancestral nervousness, alcoholism, prostitution and criminal behavior, a bias that remained widespread well into the mid-20th century. Nazi physicians invoked the theory of heritable “mental degeneration” to justify wholesale extermination of schizophrenics. Electro-convulsive therapy (ECT, or “electroshock therapy”) was widely applied to treat schizophrenia, depression, homosexuality, and criminal behavior for over 30 years, gradually abandoned (at least in its original form) after years of abusive application to subdue patients, demonized in the 1975 movie, “One Flew Over the Cuckoo’s Nest,” depicting the author’s real-life experience with ECT.

Long after a theory or practice has been discredited, it can persist, refusing to die. The new and improved may not be adopted into mainstream practice for years, even decades.

Back to the 21st century: What if you realized that, by quirks of human nature and the uneven adoption of health information, your doctor practiced medicine appropriate for 1985? 1975?

While digital information nowadays is transmitted at the speed of light, disseminating as fast as it takes the next juicy tidbit to be “virally” reproduced via social networking websites, it’s the human factor that still operates with the inertia of human behavior. Habits and attitudes slow the adoption of new information in time measured not in seconds, but in years or decades.

A century ago, 20 years were required for the new technology of blood pressure measurement to be adopted after its introduction in the U.S. in 1910, since physicians were long comfortable with the practice of “pulse palpation” (feeling the pulse). (The arcane language of pulse palpation persists to this day, terms like “pulsus parvus et tardus,” the slow rising pulse of a stiff aortic valve; and the "water-hammer" pulse of a leaking aortic valve.)

The discovery of new, health-changing information today in the 21st century disseminates through the ranks of modern healthcare providers at much the same pace as measuring blood pressure did in the early 20th century.

It’s also tempting to paint American medicine as a fiefdom intent on maintaining exclusive rein over health information. Look back over the hierarchical relationship of medicine over nursing in the past century: When blood pressure measurement was adopted on a broad scale in the 1930s, it was practiced only by physicians, since nurses were deemed incapable. (Modern-day nurses should surely have a hearty laugh over this.) Stethoscopes, around even longer than blood pressure cuffs, weren’t permitted to fall into the hands of nurses until the 1960s, since the medical community feared that nurses might command too much control over patient care. Even after nurses were permitted to have their own stethoscopes, great pains were taken to be certain the nurses’ version was readily distinguishable from the “real” tool wielded by physicians; nurses’ stethoscopes were therefore labeled “nurse-o-scopes,” or “assistoscopes,” and were required to be smaller and flimsier.

Old and ineffective doesn’t always give way to new and better at once; it is slowed by habit as well as an unwillingness to relinquish control.

Somehow technology marches on. But it does so unevenly, sweeping some along in its first wave, others in its wake, some never at all.

Just as effective antibiotics to cure tuberculosis were available for 20 years while surgeons continued to remove patients’ lungs, so better solutions to heart disease are already available but not yet employed by your neighborhood physician. The primary care physician may have heard about some of the newest means to prevent heart disease, but is too overwhelmed with the day-to-day of sore throats, diarrhea, and rashes. Cardiologists, intent on inserting the next best stent or defibrillator, have little but passing interest in strategies that might halt or reverse the heart disease that can be “managed,” no matter how imperfectly, with procedural solutions like angioplasty and bypass surgery. We should bear these flawed human tendencies in mind as we explore the world of heart disease prevention.

We need look no farther than the front page of the newspaper to find evidence of the failure of present-day heart disease detection and management. Over the past several years, headlines have carried the likes of Tim Russert, Bill Clinton, Larry King, Dick Cheney, David Letterman, Tommy Lasorda, Ed Bradley, Mike Ditka, Walter Cronkite, Alberto Salazar, all heart disease sufferers. Some, like talk show host David Letterman, survived their brush with heart catastrophe and underwent successful bypass surgery. Others, like marathoners Fixx and Salazar, raised none of the conventional red flags for heart disease. All received standard, “modern” medical care . . . all the way up to their heart attack, bypass surgery, or untimely death.

Like the sphygnomanometer (blood pressure) cuffs of 1910, Track Your Plaque represents an example of the new. But, unlike the simple practice of taking blood pressure in the early 20th century, Track Your Plaque represents an entirely new way to look at coronary heart disease: a new way to measure it, a new way to identify its causes, and a new way to seize control over it, often to the point of achieving reversal of the process. It also puts control over much of this process into your hands and away from hospitals, cardiologists, and heart procedures. 

I could speak of revealing “secrets,” but that’s not true. In Track Your Plaque, I simply convey information about heart disease that you were likely unaware existed, strategies that doctors fail to discuss. I assemble them into a “package” that, together, create an enormously empowering unique approach to prevent heart disease and heart attack.

Track Your Plaque also challenges the high-tech status quo, practices that occupy exalted places in the enormous cardiovascular healthcare machine that has dominated American healthcare for the past 40 years. I propose that high-tech hospital procedures should join the practice of ECT for homosexuality and insanity¾and become yet another relic of the past.

What are "normal" triglycerides?

12. April 2011 William Davis (67)
Among the most neglected yet enormously helpful values on any standard cholesterol panel is the triglyceride value.

Triglycerides traverse the bloodstream by hitching a ride on water (serum)-soluble lipoproteins, or lipid-carrying proteins. We measure triglycerides as an indirect index of triglyceride-containing lipoproteins.

Triglycerides are a basic currency of energy. While the average American ingests around 300 mg of cholesterol per day, he or she also ingests 60,000-120,000 mg (60-120 grams) of triglycerides, i.e., 200 to 400 times greater amounts, from fat intake. Zero triglycerides in the diet or in the bloodstream is not an option.

But what represents too much triglycerides in the bloodstream? There are several observations to help us make this determination:

1) When fasting triglycerides are 133 mg/dl or greater, 80% of people will show show at least some degree of small LDL particles.

2) When fasting triglycerides are 60 mg/dl or less, most (though not all, since genetic factors enter into the picture) people will show little to no small LDL particles.

3) When fasting triglycerides are 200 mg/dl or greater, small LDL particles will dominate and large LDL particles will be in the minority or be gone entirely.

4) When triglycerides are 88 mg/dl or greater after eating, then risk for heart attack is doubled. Non-fasting triglycerides in the 400+ mg/dl range are associated with 17-fold greater risk for heart attack.



From Austin et al 1990. "Phenotype A" means that large LDL particles dominate; "phenotype B" means that small LDL particles dominate.

Note that conventional "wisdom" (i.e., NCEP ATP-3 guidelines) is that triglycerides of up to 150 mg/dl are okay, a level that virtually guarantees expression of small LDL particles and increased cardiovascular risk.

Based on observations like these, in the Track Your Plaque program we aim for fasting triglycerides of no higher than 60 mg/dl and postprandial (after-meal) triglycerides of no more than 90 mg/dl.

Curiously, while fat intake (i.e., triglyceride intake) plays a role in determining postprandial triglyceride blood levels, it's carbohydrate intake that plays a much larger role. That will be an issue for another day.

1985: The Year of Whole Grains

9. April 2011 William Davis (30)
In 1985, the National Cholesterol Education Panel delivered its Adult Treatment Panel guidelines to Americans, advice to cut cholesterol intake, reduce saturated fat, and increase "healthy whole grains" to reduce the incidence of heart attack and other cardiovascular events.

Per capita wheat consumption increased accordingly. Wheat consumption today is 26 lbs per year greater than in 1970 and now totals 133 lbs per person per year. (Because infants and children are lumped together with adults, average adult consumption is likely greater than 200 lbs per year, or the equivalent of approximately 300 loaves of bread per year.) Another twist: The mid- and late-1980s also marks the widespread adoption of the genetically-altered dwarf variants of wheat to replace standard-height wheat.

In 1985, the Centers for Disease Control also began to track multiple health conditions, including diabetes. Here is the curve for diabetes:


Note that, from 1958 until 1985, the curve was climbing slowly. After 1985, the curve shifted sharply upward. (Not shown is the data point for 2010, an even steeper upward ascent.) Now diabetes is skyrocketing, projected to afflict 1 in 3 adults in the coming decades.

You think there's a relationship?

Have some more

7. April 2011 William Davis (37)
Wheat, via exorphin effects, is an appetite stimulant. Eat a whole wheat bagel or bran muffin, you want another. You also want more of other foods. You also want something to eat every two hours due to widely-swinging insulin-glucose responses: blood sugar high followed by a sharp downturn that triggers a powerful impulse to eat (thus the cravings for a snack at 9 and 11 a.m. after a 7 a.m. breakfast).

If wheat is a stimulant of appetite, then removing it should yield reduced appetite and reduced calorie intake. That is precisely what happens.

When wheat products are removed from the diet--without calorie restriction, without counting fat or carbohydrate grams, no exercise program, no cleansing regimen, no skipping meals . . . nothing--calorie intake drops 350 to 400 calories per day. This calorie figure remains curiously consistent across multiple studies in which wheat was eliminated.

400 calories per day results in 21 lbs lost over 6 months, based just on calories. (3500 calories per pound lost.) That is what happens in wheat elimination diets: 21-26 lbs lost over 6 months.

Wheat is the processed food industry's nicotine, a means of ensuring repeat food purchases. It's also low-cost (subsidized by the U.S. government), high-yield, an ingredient that even has its very own withdrawal syndrome should you miss a "hit."
