Restaurant eating: A fructose landmine

13. January 2011 William Davis (25)
There is no remaining question that fructose is among the worst possible things humans can consume.

Followers of the Heart Scan Blog already know this, from conversations like The LDL-Fructose Disconnect, Where do you find fructose?, and Goodbye, fructose.

But fructose, usually as either high-fructose corn syrup (44%, 55%, occasionally higher percentage fructose) or sucrose (50% fructose), is ubiquitous. I've seen it in the most improbable places, including cole slaw, mustard, and dill pickles.

It's reasonably straightforward to avoid or minimize fructose exposure while eating at home, provided you check labels and focus on foods that don't require labels (like green peppers, salmon, and olive oil, i.e., unprocessed foods). But when you choose to eat at a restaurant, then all hell can break loose and fructose exposure can explode.

So what are some common and unsuspected fructose sources when eating at a restaurant?

Salad dressings--Dressings in all stripes and flavors are now made with high-fructose corn syrup and/or sucrose. This is especially true of low-fat, non-fat, or "lite" dressings, meaning oils have been replaced by high-fructose corn syrup. It can also be true of traditional non-low-fat dressings, too, since high-fructose corn syrup is just plain cheap.

Olive oil and vinegar are still your safest bets. I will often use salsa as a dressing, which works well.

Sauces and gravies--Not only can sauces be thickened with cornstarch, many pre-mixed sauces are also made with high-fructose corn syrup or sweetened with sucrose. Barbecue sauce is a particular landmine, since it is now a rare barbecue sauce not made with high-fructose corn syrup as the first or second ingredient. Sauces for dipping are nearly always high-fructose corn syrup-based.

Ketchup--Yup. Good old ketchup even is now made with high-fructose corn syrup. In fact, you should be suspicious of any condiment.

Highball, Bloody Mary, Margarita, Daiquiri, beer--Even the before-dinner or dinner drink can have plenty of fructose, particularly if a mix is used to make it. While Blood Marys seem the most benign of all, adorned with celery, pickle, and olive, just take a look at the ingredient label on the mix used: high-fructose corn syrup.

Fructose is a stealth poison: It doesn't immediately increase blood sugar; it doesn't trigger any perceptible effect like increased energy or sleepiness. But it is responsible for an incredible amount of the health struggles in the U.S., from obesity, to diabetes, to hyperlipidemias and heart disease, to arthritis, to cataracts.

A glycation rock and a hard place

12. January 2011 William Davis (15)
Advanced Glycation End-products, or AGEs, the stuff of aging that mucks up brains, kidneys, and arteries, develop via two different routes: endogenous (from within the body) and exogenous (from outside the body).

Endogenous AGEs develop via glycation. Glycation of proteins in the body occurs when there are glucose excursions above normal. For instance, a blood glucose of 150 mg/dl after your bowl of stone-ground oatmeal causes glycation of proteins left and right, from the proteins in the lens of your eyes (cataracts), to the proteins in your kidneys (proteinuria and kidney dysfunction), to skin cells (wrinkles), to cartilage (brittle cartilage followed by arthritis), to LDL particles, especially small LDL particles (atherosclerosis).

At what blood sugar level does glycation occur? It occurs even at "normal" glucose levels below 100 mg/dl (with measurable long-term cardiovascular effects as low as 83 mg/dl). In other words, some level of glycation proceeds even at blood glucose levels regarded as normal.

There's nothing we can do about the low-level of glycation that occurs at low blood sugar levels of, say, 90 mg/dl or less. However, we can indeed do a lot to not allow glycation to proceed more rapidly, as it inevitably will at blood sugar levels higher than 90 mg/dl.

How do you keep blood sugars below 90 mg/dl to prevent excessive glycation? Avoid or minimize the foods that cause such rises in blood sugar: carbohydrates.

What food increases blood sugar higher than nearly all other known foods? Wheat.

Is einkorn the answer?

11. January 2011 William Davis (14)
People ask: "What if I would like a piece of bread or other baked product just once in a while? What is safe?"

Eli Rogosa, Director of The Heritage Wheat Conservancy, believes that a return to the wheat of our ancestors in the Fertile Crescent, circa 10,000 years ago, is the answer.

Former science teacher, now organic farmer, farm researcher, and advocate of sustainable agriculture, Eli has been reviving "heritage" crops farmed under organic conditions, some of her research USDA-funded.

In particular, Eli has been cultivating original 14-chromosome ("diploid") einkorn wheat. Although einkorn contains gluten (in lesser quantities despite the higher total protein content), the group of proteins that trigger the immune abnormalities of celiac disease and other immune phenomena, Eli tells me that she has witnessed many people with a variety of wheat intolerances, including celiac disease, tolerate foods made with einkorn wheat. (The variety of glutens in einkorn differ from the glutens of the dwarf mutant that now dominate supermarket shelves.)

Eli travels to Israel every year, returning with "heritage" seeds for wheat and other crops. She formerly worked in the Israel GenBank as Director of the Ancient Wheat Program. She has written a brochure that describes her einkorn wheat.

Eli sent me 2 lb of her einkorn grain that nutritionist, Margaret Pfeiffer, and I ground into bread. Our experience is detailed here. My subsequent blood sugar misadventure, comparing einkorn bread to conventional organic whole wheat bread is detailed here, followed by the odd neurologic effects I experienced here.

Anyone else wishing to try this little ancient wheat experiment with einkorn can also obtain either the unground grain or ground flour through Eli's website, www.growseed.org. Most recently, einkorn pasta is being retailed under the Jovial brand at Whole Foods Market.

If anyone else makes bread or any other food with Eli's einkorn wheat, please let me know:

1) Your blood sugar response (before and 1 hour after consumption)
2) Whether you experienced any evidence of wheat intolerance similar to what you experienced with conventional wheat, e.g., rash, acid reflux, gas and cramping, moodiness, asthma, etc.

But remember: Wheat effects or no, einkorn is still a grain. My belief is that humans do best with little or no grain. The einkorn experience is an effort to identify reasonable compromises so that you and I can have a piece of birthday cake once a year without getting sick.

Genetic incompatibility

10. January 2011 William Davis (29)
Peter has lipoprotein(a), or Lp(a), a genetic pattern shared by 11% of Americans.

It means that Peter inherited a gene that codes for a protein, called apoprotein(a), that attaches to LDL particles, forming the combined particle Lp(a). It also means that his overall pattern responds well to a high-fat, high-protein, low-carbohydrate diet: The small LDL particles that accompany Lp(a) over 90% of the time are reduced, Lp(a) itself is modestly reduced, other abnormalities like high triglycerides (that facilitate Lp(a)'s adverse effects) are corrected. Small LDL particles are, by the way, part of the genetic "package" of Lp(a) in most carriers.

Peter also has another gene for Apo E4, another genetically-determined pattern shared by 19% of Americans. (Another 2% of Americans have two "doses" of Apo E4, i.e., they are homozygotes for E4.) This means that the Apo E protein, normally responsible for liver uptake and disposal of lipoproteins (especially VLDL), is defective. In people with Apo E4, the higher the fat intake, the more LDL particles accumulate. (The explanation for this effect is not entirely clear, but it may represent excessive defective Apo E-enriched VLDL that competes with LDL for liver uptake.) People with Apo E4 therefore drop LDL (and LDL particle number and apoprotein B) with reductions in fat intake.

This is a genetic rock-and-a-hard-place, or what I call a genetic incompatibility. If Peter increases fat and reduces carbohydrates to reduce Lp(a)/small LDL, then LDL measures like LDL particle number, apoprotein B, and LDL cholesterol will increase. Paradoxically, sometimes small LDL particles will even increase in some genetically predisposed people.

If Peter decreases fat and increases carbohydrates, LDL particle number, apoprotein B, and LDL cholesterol will decrease, but the proportion of small LDL will increase and Lp(a) may increase.

Thankfully, such "genetic incompatibilities" are uncommon. In my large practice, for instance, I have about 5 such people.

The message: If you witness paradoxic responses that don't make sense or follow the usual pattern, e.g., reductions in LDL particle number, apoprotein B, and small LDL with reductions in their dietary triggers (i.e., carbohydrates, especially wheat), then consider a competing genetic trait such as Apo E4.

The folly of an RDA for vitamin D

9. January 2011 William Davis (26)
Tom is a 50-year old, 198-lb white male. At the start, his 25-hydroxy vitamin D level was 28.8 ng/ml in July. Tom supplements vitamin D, 2000 units per day, in gelcap form. Six months later in January (winter), Tom's 25-hydroxy vitamin D level: 67.4 ng/ml.

Jerry is another 50-year old white male with similar build and weight. Jerry's starting summer 25-hydroxy vitamin D level: 26.4 ng/ml. Jerry takes 12,000 units vitamin D per day, also in gelcap form. In winter, six months later, Jerry's 25-hydroxy vitamin D level: 63.2 ng/ml.

Two men, similar builds, similar body weight, both Caucasian, similar starting levels of 25-hydroxy vitamin D. Yet they have markedly different needs for vitamin D dose to achieve a similar level of 25-hydroxy vitamin D. Why?

It's unlikely to be due to variation in vitamin D supplement preparations, since I monitor vitamin D levels at least every 6 months and, even with changes in preparations, dose needs remain fairly constant.

The differences in this situation are likely genetically-determined. To my knowledge, however, the precise means by which genetic variation accounts for it has not been worked out.

This highlights the folly of specifying a one-size-fits-all Recommended Daily Allowance (RDA) for vitamin D. The variation in need can be incredible. While needs are partly determined by body size and proportion body fat (the bigger you are, the more you need), I've also seen 105 lb women require 14,000 units and 320-lb men require 1000 units to achieve the same level of 25-hydroxy vitamin D.

An RDA for everyone? Ridiculous. Vitamin D is an individual issue that must be addressed on a person-by-person basis.

Heart scan: Standard of care?

6. January 2011 William Davis (0)
If coronary disease is easy to detect by measuring coronary calcium, shouldn't this represent the standard of care?

In other words, if you've been seeing your doctor and he/she has been monitoring cholesterol levels and, inevitably, talks about statin drugs, then you have a heart attack, unstable angina, or die--yet never knew you had heart disease--isn't this negligence?

Coronary calcium, and thereby coronary atherosclerotic plaque, are markers for the disease itself. Unlike cholesterol, high blood pressure, etc., that represent risk factors for coronary atherosclerotic plaque, coronary calcium is a measure of total plaque: "soft" elements like lipid collections, necrotic tissue, fibrous tissue, as well as "hard" elements like calcium. Because calcium occupies 20% of total atherosclerotic plaque volume, it can be used as an indirect "dipstick" for total plaque.

So why isn't an unexpected heart attack, hospitalization for unstable heart symptions, emergency bypass, etc., not regarded as potential malpractice? These are not benign events, but potentially life-threatening.

The costs of doing drug business?

6. January 2011 William Davis (28)
Here's a telling situation.

Liz had been on prescription niacin, Niaspan, 1500 mg per day (3 x 500 mg tablets) for several years to treat her severe small LDL pattern and familial hypertriglyceridemia (triglycerides 500-1000 mg/dl). Because her health insurance had been paying for the "drug," she insisted on taking the prescription form.

A change in insurance, however, meant that the Niaspan was no longer covered. Her pharmacy wanted to charge $227 per month.

Liz came to the office in tears, worried that she was going to have to choke up $227 per month. I reminded her that, as I had told her several years ago, she could easily replace the Niaspan with over-the-counter Sloniacin or Enduracin. Both release niacin over approximately 6 hours, just like Niaspan.

Here are the prices I've seen with Sloniacin, 100 tablets of 500 mg:

Walgreens: $15.99
Walmart: $12.99
Costco: $8.99

So the most expensive source, Walgreens, would cost Liz just under $15.99 per month to take 1500 mg per day.

$15.99 versus $227.00 per month for preparations that are highly similar. Hmmmmmm.

I wonder what the $211.01 extra per month goes towards? Admittedly, Abbott Labs, the current company selling Niaspan (after Abbott acquired Kos), has invested in a few clinical trials, such as ARBITER-HALTS6. But does supporting research justify this much difference, a difference that amounts to $2532 over a year? If just 100,000 patients are prescribed Niaspan at this dose (a typical dose), this generates $253 million.

Is the cost of developing and marketing a supplement-turned-drug that great? Is this justifiable? Is it any wonder that our health insurance premiums continue to balloon?

I use Sloniacin and Enduracin almost exclusively.

Measurement

4. January 2011 William Davis (9)
A crucial component of self-empowerment in healthcare is to be able to measure various health parameters. More and more measurement tools are entering the direct-to-consumer arena.

Quantification of various phenomena is important in managing many aspects of health. Imagine a carpenter trying to build a house without the use of a tape measure, level, or other measuring tools. In health, as in building a house, measurement, adjustment, and correction are critical.

Among the most helpful health measurement tools:

Blood glucose meters--Blood glucose meters aren't just for diabetics. They are among the most powerful weight loss tools available.

Blood pressure cuffs--There's no better way to assess blood pressure than to assess it under all the varied conditions of life: When you're tired, when you're excited, when you're upset, when you're happy, hungry, stomach full, morning, night. This is a lot better than the one isolated measure in the doctor's office.

Digital thermometers--Your first a.m. oral temperature is a great way to assess thyroid status. We aim to maintain first a.m. oral temperature around 97.3 degrees F, the normal human temperature upon arising that reflects normal thyroid function. (No, Dr. Broda Barnes fans, axillary temperatures should NOT be used due to flagrant variation from right armpit to left armpit, modifying effects of clothing and ambient temperature, etc. Oral temperature tracks internal, "core," temperature fluctuations reliably, including circadian variation, far better than axillary temperatures.)

Fingerstick blood tests--An incredible number of blood tests are now available just by performing a simple fingerstick in your kitchen or bathroom. You can get 25-hydroxy vitamin D, lipids, thyroid measures (TSH, free T3, free T4), hormones (DHEA, testosterone, estrogens). And the list is growing rapidly. Salivary tests are also growing in number for many of the same measures.

A variation on fingerstick blood tests are devices like CardioChek that allow you to do a fingerstick, but also run the test on your own device at home. (The CardioChek device tests total cholesterol, triglycerides, and HDL.)

Urine pH--You can dipstick your own urine to assess the relative acidity or alkalinity of your lifestyle. Acid pH (7 or below) suggests that diet is weighed too heavily in favor of animal products and grains. An alkaline pH (above 7) suggests plentiful vegetables and fruits, not counteracted by animal products and grains.

There are many more, including the ZEO device to monitor sleep quality, RESPeRATE for reduction of blood pressure, HeartMath to manage stress and augment the parasympathatic (relaxation) response. We've come a long way compared to the health monitoring devices of just 25-30 years ago.

Anyway, that's a partial list. Given the rapid advances in technology that allow such home tests, I anticipate a much longer list in the coming few years.

For some perspective on how far these devices have come, here's a great graphic of an early sphygmomanometer, or blood pressure gauge.

I lost 37 lbs with a fingerstick

30. December 2010 William Davis (34)
Jack needed to lose weight.

At 5 ft 7 inches, he weighed in at 273 lbs, putting his BMI at a sobering 42.8. (A BMI of 30 or above is classified as "obese.") In addition to lipoprotein(a), Jack had an extravagant quantity of small LDL (the evil "partner" of lipoprotein(a)), high triglycerides, and blood sugars in the diabetic range. With a heart scan score of 1670, Jack had little room for compromises.

Try as he might, Jack could simply not stick to the diet I urged him to follow. Three days, for instance, of avoiding wheat was promptly interrupted by his wife's tempting him with a nice BLT sandwich. This triggered his appetite, with diet spiraling downward in short order.

So I taught Jack how to check his blood sugars using a fingerstick device, what I call the most important weight loss tool available. I asked Jack to check his pre-meal blood glucose and his one-hour after-meal blood glucose and not allow the after-meal blood glucose to rise any higher than the pre-meal. For example, if blood glucose pre-meal was 115 mg/dl, after-meal blood glucose should be no higher than 115 mg/dl.

If any food or combination of foods increase blood glucose more than the pre-meal value, then eliminate the culprit food or reduce the portion size. For example, if dinner consists of baked salmon, asparagus, and mashed potatoes, and pre-meal blood glucose is 115 mg/dl, post-meal 155 mg/dl, reduce or eliminate the mashed potatoes. If slow-cooked, stone ground oatmeal causes blood glucose to increase from 115 mg/dl to 185 mg/dl (a typical response to oatmeal), then eliminate it.

Having immediate feedback on the effects of various foods finally did it for Jack: It identified foods that were triggering excessive blood sugar rises (and thereby insulin) and foods that did not.

What Jack did not do is limit or restrict calories. In fact, I asked him to eat portion sizes that left him comfortable. There was no need to reduce calories, push the plate away, etc. Just don't allow blood sugars to rise.

Six months later, Jack came back 37 lbs lighter. And he got there without calorie-counting, without regulating portion sizes, without hunger.

The two kinds of small LDL

27. December 2010 William Davis (17)
You won't find this in any publication nor description (at least ones that I've come across) about the ubiquitous small LDL particles. It's an observation I've made having obtained thousands of advanced lipoprotein panels of the sort that break lipoproteins down by size. I've discussed this issue previously here. But small LDL is so ubiquitous, not addressed by conventional strategies like statin drugs or fat restriction (it is made worse, in fact, by reducing fat in the diet), that it is worth keeping at the top of everyone's consciousness.

(Because most of the lipoprotein analyses performed in my office are done via NMR, I will discuss in terms relevant to NMR. This does not necessarily mean that similar observations cannot be made with centrifugation, i.e, VAP from Atherotech, or gel electropheresis from Berkeley, Boston Heart Lab, Spectracell, and others).

There are two basic varieties of small LDL particles:

1) Genetically-programmed--e.g., via cholesteryl-ester transfer protein (CETP) activity
2) Acquired--via carbohydrate consumption


It means that people with acquired small LDL from carbohydrate consumption can reduce small LDL to zero with reduction of carbohydrates, especially the most small LDL-provoking foods of all: wheat, cornstarch, and sucrose.

It also means that people who have small LDL for genetically-determined reasons can only minimize, not eliminate, small LDL. By NMR, we struggle to keep small LDL in the 300-600 nmol/L range when genetically-determined. (People typically start with 1400-3000 nmol/L small LDL particles prior to diet changes and other efforts.) We can only presumptively identify genetically-determined small LDL when all the appropriate efforts have been made, including reduction in weight to ideal, yet small LDL persists.

Here is where we need better tools: when you've done everything possible, yet small LDL persists.

While we break LDL particles (NOT LDL cholesterol, the crude and misleading way of viewing atherosclerosis causation) down by size, it's really about all the undesirable characteristics that accompany small size:

--Distortion of Apo B conformation--i.e., the primary protein that directs LDL particle fate is distorted, making it less likely to be cleared by the liver but more likely to be taken up by inflammatory (macrophages) in the artery wall, creating plaque. It means that small LDL particles linger for a longer time than larger particles.

--Small LDLs are more oxidation-prone. Oxidized LDL are more avidly taken up by inflammatory macrophages.

--Small LDLs are more glycation-prone.

--Small LDLs are more adherent to structural tissues, e.g., glycosaminoglycans, that reside in the artery wall.

You and I cannot measure such phenomena, so we resort to distinguishing LDL particles by size.

The drug industry believes it may have a solution to small LDL in the form of CETP-inhibiting drugs, like anacetrapib. In the way of nutritional solutions beyond carbohydrate reduction, weight loss/exercise, niacin, vitamin D normalization, and omega-3 fatty acid supplementation, there are exciting but very preliminary data surrounding the possibility that anthocyanins may inhibit CETP activity. Having toyed with this concept for the past 6 months, I remain uncertain how meaningful the effect truly is, but it is harmless, since we obtain anthocyanins from foods colored purple or purplish, such as blackberries, blueberries, cherries, red leaf lettuce, red cabbage, etc.

I welcome any unique observations on this issue.

Almonds are the new wheat

29. September 2011 William Davis (31)
Once you eliminate this genetically-altered Frankengrain called modern wheat, the diet should center around vegetables, nuts, healthy oils like olive and coconut, fish, meats, cheese, olives, avocados and other real whole foods. This is, in fact, the diet that I have advocated in my heart disease prevention practice, as well as my online program for prevention and reversal of heart disease.

But what if you'd like a piece of cheesecake or a nice slice of dessert bread---but you don't want to gain two pounds, spend 48 hours in the bathroom suffering with diarrhea and cramps, 3 weeks of joint pains and leg swelling, wade through mental "fog," anxiety, and rage just because you had that momentary indulgence---as you would with wheat?

That's why I've been focusing on recipes that allow you to have something familiar, e.g., chocolate coconut bread or biscotti, but using ingredients that will not generate the metabolic contortions triggered by wheat.

On perusing these recipes, you will notice that there are recurring ingredient themes. Many of the same ingredients pop up time and again. Among the most frequent, versatile, user-friendly, and tasty: Almonds.

You can use almonds as ground whole almonds, ground blanched almonds for a finer texture, ground roasted almonds, almond butter (though, for maximum health benefits, I prefer the ground whole almonds). Ground almonds allow you to recreate muffins, breads, scones, pizza crust, pie crust, biscotti, and cookies with health benefits that exceed that of whole wheat---but with none of the downside: no weight gain, no high blood sugar, no triggering of small LDL particles (#1 cause of heart disease in the U.S.), no accumulation of visceral fat, no appetite stimulation.

In short, you just have your chocolate almond biscotti or mocha cupcake and enjoy it, no health price to pay. So I call almonds the new wheat, except better.

Being regular is dangerous to your health

25. September 2011 William Davis (21)
No, I'm not referring to your daily morning ritual in the bathroom. I'm talking about heart rate.

Counterintuitively, a perfectly regular heart rate is a marker of poor health. People with perfect regularity of heart rate have more heart attacks, for instance.

Regularity of heart rate occurs more commonly in people with hypertension and other metabolic derangements, and it signals increased risk for both heart attack and death. A perfectly regular heart rate, i.e., no variation in the time interval from beat to beat, suggests that the parasympathetic nervous system, the component of automatic ("autonomic") nervous system control that is associated with the relaxation response, feelings of well-being, quiet, and relaxation, is weak. It also means that the opposing sympathetic nervous sytem that regulates the "fight or flight," adrenaline-like response is allowed to be dominant. Dominance of the sympathetic over the parasympathetic system generates regularity of heart rate. Heart rate also tends to be faster, e.g., 85 beats per minutes rather than 55 or 60 beats per minute. So perfect regularity, as well as increased rate, is undesirable.

What we want is irregularity of heart rate. But not irregularity that occurs chaotically with no rhyme or reason. More precisely, we want variability in heart rate. And we want variability to occur in synchrony with breathing, i.e., the respiratory cycle.

The ideal response is:

1) increase in heart rate with inspiration

2) decrease in heart rate with expiration.

Heart rate in healthy people typically varies 15-20 beats per minute within the respiratory cycle, e.g., 60 bpm at end-exhalation, 80 bpm at end-inspiration.

Restoration of increased heart rate variability is associated with reduced blood pressure, reduced blood sugars (HbA1c), reduced inflammatory markers and cortisol (associated with stress), even an increase in DHEA levels. Feelings of well-being and calm also develop.

Among the strategies to consider to restore heightened heart rate variability and slowed heart rate include:

--Omega-3 fatty acid supplementation
--Exercise
--Weight loss
--Deep breathing exercises
--Meditation, prayer, and biofeedback

For our Track Your Plaque purposes, we are folding in the HeartMath strategies, i.e., use of a heart rate monitor that calculates heart rate variability in the context of respiratory cycle. If you've not already done so, take a look at the two Special Reports devoted to this topic on the Track Your Plaque website.

You mean weight loss is hazardous to your health?

23. September 2011 William Davis (11)
In my last Heart Scan Blog post, What is this wacky thing called weight loss?, I discussed how weight loss is associated with distortions in cholesterol and blood sugar values that can be very confusing, often leading your doctor to wrongly and unnecessarily prescribe drugs--since he/she likely rarely sees weight loss.

Blog reader, Donald K., posted his enlightening story:

I experienced this very thing.

After losing serious weight from the eliminating wheat, processed, and sugary foods (1 year in total) I lost 130 pounds. When I was nearly finished I went to see my doctor. He wanted to put me on statins. I explained to him how the data does not support application to me (no evidence of heart disease) and I got the mantra about standards of practice, etc, etc. I held my ground and decided I am much happier eating dairy, eggs, grass fed beef, wild caught fish, and as much raw foods (nuts, veggies, fruits) as my body desires to treat my health parameters.

Maintaining weight, it is easy. My BMI (23 down from 40) has remained constant for a few months now. You are right: metabolic processes definitely change. I no longer have sensations of glucose fluctuations or an uncontrolled appetite. I can only imagine the improved hormone regulation and metabolic communication going on inside my body.

The symptoms from obesity, all gone. Goodbye sleep apnea, hypertension, hemorrhoids, arrhythmias, gastroinestinal disruptions, smelly body, chaffing thighs, and others not mentioned. The positive effects are just as dramatic, but I don’t want to ramble on.

Weight loss? What is it? Getting your life back!

Brace yourself: If you are following the nutrition advice posted here and in the Track Your Plaque program, or the discussion I've initiated in Wheat Belly, then you may find yourself in the very same health predicament as Donald. Arm yourself to protect yourself against the drug-wielding ways of doctors. No, weight loss to achieve ideal weight is definitely not bad for health. But your doctor's misinterpretation of its effects can be!

What is this wacky thing called "weight loss"?

20. September 2011 William Davis (41)
I've discussed this before, but it has proven such an (encouragingly!) frequent issue that I thought it was worth discussing once again.

What happens when you lose weight?

The process of weight loss is characterized by multiple shifts in metabolic patterns that can be confusing. To the uninitiated eye, weight loss can look like a disastrous distortion in metabolism. The naive doctor on seeing your lab values, for instance, might insist you take a statin drug, a fibrate like Tricor (to reduce triglycerides or increase HDL), or simply berate you for your bad health habits--when it's actually a good thing you've accomplished.

So when you lose weight, say, 30 pounds in 3 months, what have you accomplished?

Energy stored as fat, especially from visceral fat stores, is mobilized into the bloodstream. It floods the bloodstream as fatty acids and triglycerides. These fatty acids and triglycerides don't occur in isolation, but interact with other particles and metabolic patterns. The resulting blood patterns include:

--Increased triglycerides--An increase in triglycerides, for instance, from 90 mg/dl to 200 mg/dl in the midst of weight loss is common.

--Reduced HDL--The flood of triglycerides leads to increased degradation of HDL, thus a drop. A drop in HDL from, say, 40 mg/dl to 27 mg/dl--very frightening to people--is exceptionally common.

--Increased blood sugar--The flood of fatty acids and triglycerides results in insulin resistance, leading to higher blood sugars. It is not uncommon for someone with pre-diabetes to develop diabetic-range blood sugars, or a non-diabetic to show pre-diabetic blood sugars.

--Increased small LDL particles--Though small LDL is highly variable during weight loss. When it does happen, it's probably from the interaction of VLDL (triglycerides) with LDL particles and the reaction that overloads LDL particles with triglycerides and conversion to small LDL particles.

So why don't doctors often recognize these patterns when a patient loses weight? Because they rarely see it. Most of my colleagues are accustomed to having patients come back with weight gain, getting heavier and heavier each time. Lose weight? Impossible! So they just don't recognize weight loss effects when they see it. As followers of The Heart Scan Blog know, a frequent conversation around here is "Am I too skinny?" or "How do I stop losing weight?"

The solution: Be patient. Be patient and wait about two months after a weight plateau has been achieved. That's when the numbers "settle down" and you see marked drops in triglycerides, increases in HDL, drops in blood sugar, reductions in small LDL.

As with many things, it's all about timing.

Why small LDL particles are the #1 cause of heart disease in the US

15. September 2011 William Davis (77)
Ask your doctor: What is the #1 cause of heart disease in the US?

Let's put aside smoking, since it is an eminently modifiable risk and none of those crazies read this blog anyway. What will your doctor say? Most like he or she will respond:

High cholesterol or high LDL cholesterol

Too much saturated fat

Obesity

Pfizer, Merck, AstraZeneca and their kind would be overjoyed to know that they can add your doctor to their eager following.

I'd tell you something different. I would tell you that small LDL particles are, by far and away, the #1 cause for heart disease. I base this claim on several observations:

--Having run over 10,000 lipoprotein panels (mostly NMR) over the past 15 years, it is a rare person who does not have a moderate, if not severe, excess of small LDL particles. 50%, 70%, even 90% or more small LDL particles are not rare. Over the course of a year, the only people who show no small LDL particles are slender, athletic, pre-menopausal females.

--In studies in which lipoproteins have been quantified in people with coronary disease, small LDL particles dominate, just as they do in my office. Here's a 2006 review.

--Small LDL is largely the province of people who consume carbohydrates, such as the American population instructed to "cut fat and eat more healthy whole grains." Conventional diet advice has therefore triggered an expllosion in small LDL particles.

--When fasting triglycerides exceed 60 mg/dl, small LDL particles increase as a proportion of total LDL particles. This includes the majority of the US population. (This ignores postprandial, or after-eating, triglycerides, which also contribute to small LDL formation.)

If you were to read the data, however, you might conclude that small LDL affects a minority of people. This is because in most studies small LDL categorize it as either "pattern B," meaning exceeding some arbitrary threshold of percentage of small LDL particles, versus "pattern A," meaning falling below that same arbitrary threshold.

Problem: There is no consensus on what percentage of small LDL particles should mark the cutoff between pattern A vs. pattern B. In many studies, for instance, people with 50% small LDL particles are called "pattern A."

If, instead, we were to set the bar lower to identify this highly atherogenic (atherosclerotic plaque-causing) particle at, say, 20-30% of total, then the number or percentage of people with "pattern B" small LDL particles would go much higher.

I see this play out in my office and in the online program, Track Your Plaque, every day: At the start eating a low-fat, grain-filled diet with lots of visceral fat ("wheat belly") to start, they add back fat and cut out all wheat and limit carbohydrates. Small LDL particles plummet

Even moore from Jimmy Moore

14. September 2011 William Davis (8)
The ubiquitous and irrepressible Jimmy Moore posted even more commentary about the Wheat Belly phenomenon here, what he calls "The Wheat Belly Bonanza."

Is low-carb really, at its core, little more than elimination of wheat? Sure, corn, rice, and sugar exert deleterious effects. But the dominant effect--by far--is the elimination of wheat. So is the low-carb movement really, at its core, a wheat-elimination movement?

Food (non-wheat-containing, of course) for thought.

Heart Scans: An Interview with Jimmy Moore

10. September 2011 William Davis (2)
My friend, Jimmy Moore, of The Livin' La Vida Low Carb Show, posted this video of an interview I did with him.

I provide some background on how heart scanning came about and how it led to the creation of the Track Your Plaque program.

It reminds me how far we've come over the 8 years since the program got started. From its modest start as just an information resource to help people understand their heart scan score, to a comprehensive program that helps followers gain incredible control over coronary plaque and coronary risk that has now expanded to over 30 countries. High-tech heart procedures still dominate public consciousness, but the tremendous power of real heart disease prevention efforts are gaining more and more attention as each day passes.

Interview with Jimmy Moore of Livin' La Vida Low-Carb

7. September 2011 William Davis (11)
Here's my podcast interview with Jimmy Moore, host of the Livin' La Vida Low-Carb Show. (If you want to fast forward to the interview, go to time marker 41:20 on the slidebar.)



In the podcast, I talk about how the Track Your Plaque program and its focus on lipoprotein testing, along with the need to reverse the incredible epidemic of diabetes and pre-diabetes, led to elimination of all wheat from the diet and the book, Wheat Belly.

An open letter to the Grain Foods Foundation

Readers: Please feel free to reproduce and disseminate this letter any way you see fit.

Ms. Ashley Reynolds

Ms. Reynolds:

I am writing in response to the press release from the Grain Foods Foundation that describes your effort to "discredit" the assertions made in my book, Wheat Belly: Lose the wheat, lose the weight and find your path back to health. I'd like to address several of the criticisms of the book made in the release:

" . . . the author relies on anecdotal observations rather than scientific studies."
While I do indeed have a large anecdotal experience removing wheat in thousands of people, witnessing incredible and unprecedented weight loss and health benefits, I also draw from the experiences already documented in clinical studies. Several hundred of these studies are cited in the book (of the thousands available) and listed in the Reference section over 16 pages. These are studies that document the neurologic impairment unique to wheat, including cerebellar ataxia and dementia; heart disease via provocation of the small LDL pattern; visceral fat accumulation and all its attendant health consequences; the process of glycation via amylopectin A of wheat that leads to cataracts, diabetes, and arthritis; among others. There are, in fact, a wealth of studies documenting the adverse, often crippling, effects of wheat consumption in humans and I draw from these published studies.


"Wheat elimination 'means missing out on a wealth of essential nutrients.'"
This is true--if the calories of wheat are replaced with candy, soft drinks, and fast food. But if lost wheat calories are replaced by healthy foods like vegetables, nuts, healthy oils, meats, eggs, cheese, avocados, and olives, then there is no nutrient deficiency that develops with elimination of wheat. There is no deficiency of any vitamin, including thiamine, folate, B12, iron, and B6; no mineral, including selenium, magnesium, and zinc; no polyphenol, flavonoid, or antioxidant; no lack of fiber. With regards to fiber, please note that the original studies documenting the health benefits of high fiber intake were fibers from vegetables, fruits, and nuts, not wheat or grains.

People with celiac disease do indeed experience deficiencies of multiple vitamins and minerals after they eliminate all wheat and gluten from the diet. But this is not due to a diet lacking valuable nutrients, but from the incomplete healing of the gastrointestinal tract (such as the lining of the duodenum and proximal jejunum). In these people, the destructive effects of wheat are so overpowering that, unfortunately, some people never heal completely. These people do indeed require vitamin and mineral supplementation, as well as probiotics and pancreatic enzyme supplementation.


I pose several questions to you and your organization:

Why is the high-glycemic index of wheat products ignored?
Due to the unique properties of amylopectin A, two slices of whole wheat bread increase blood sugar higher than many candy bars. High blood glucose leads to the process of glycation that, in turn, causes arthritis (cartilage glycation), cataracts (lens protein glycation), diabetes (glycotoxicity of pancreatic beta cells), hepatic de novo lipogenesis that increases triglycerides and, thereby, increases expression of atherogenic (heart disease-causing) small LDL particles, leading to heart attacks. Repetitive high blood sugars that develop from a grain-rich diet are, in my view, very destructive and lead to weight gain (specifically visceral fat), insulin resistance, leptin resistance (leading to obesity), and many of the health struggles Americans now experience.

How do you account for the psychologic and neurologic effects of the wheat protein, gliadin?
Wheat gliadin has been associated with cerebellar ataxia, peripheral neuropathy, gluten encephalopathy (dementia), behavioral outbursts in children with ADHD and autism, and paranoid delusions and auditory hallucinations in people with schizophrenia, severe and incapacitating effects for people suffering from these conditions.

How do you explain the quadrupling of celiac disease over the last 50 years and its doubling over the last 20 years?
I submit to you that, while this is indeed my speculation, it is the changes in genetic code and, thereby, antigenic profile, of the high-yield semi-dwarf wheat cultivars now on the market that account for the marked increase in celiac potential nationwide. As you know, "hybridization" techniques, including chemical mutagenesis to induce selective mutations, leads to development of unique strains that are not subject to animal or human safety testing--they are just brought to market and sold.

Why does the wheat industry continue to call chemical mutagenesis, gamma irradiation, and x-ray irradiation "traditional breeding techniques" that you distinguish from genetic engineering? Chemical mutagenesis using the toxic mutagen, sodium azide, of course, is the method used to generate BASF's Clearfield herbicide-resistant wheat strain. These methods are being used on a wide scale to generate unique genetic strains that are, without question from the FDA or USDA, assumed to be safe for human consumption.

In short, my view on the situation is that the U.S. government, with its repeated advice to "eat more healthy whole grains," transmitted via vehicles like the USDA Food Pyramid and Food Plate, coupled with the extensive genetic transformations of the wheat plant introduced by agricultural geneticists, underlie an incredible deterioration in American health. I propose that you and your organization, as well as the wheat industry and its supporters, are at risk for legal liability on a scale not seen since the tobacco industry was brought to task to pay for the countless millions who died at their product's hands.

I would be happy and willing to talk to you personally. I would also welcome the opportunity to debate you or any of your experts in a public forum.

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.

NY Times Jane Brody misses the mark

9. October 2007 William Davis (6)


NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper:

"CT Scans of the Heart Come With Trade-Offs


In her report, she says:

Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.

I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.


She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent.

This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like:

--the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.

--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors.

--There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham.


Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness.

If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.

"There must be a mistake"

9. October 2007 William Davis (2)
Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!)

You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to

http://www.cureality.com/library/fl_07-001nealt51.asp


Neal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results.

After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop."

The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment.

Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal.

I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal.

Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help."

Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them.

Should this happen to you, don't be surprised. Just bite your tongue, because you know better.

Jimmy Moore Interview: Is saturated fat the villain we thought?

7. October 2007 William Davis (45)
Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore.

On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment."

Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer.

But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts.




TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program.

I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?





JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.

While we do agree on probably 99% of the basic tenets of what I describe as
"livin' la vida low-carb," the issue of saturated fat to me is one where we
indeed do not. It's not a deal breaker regarding my support for what you do
just as I'm sure you would say the same regarding your backing of what I do. If
we all agreed on everything, then what a boring world this would be!

My thinking on saturated fat has evolved since I started eating this way nearly
four years ago. Like most people, I was terrified to eat ANY fat at all because
of the abject fear that people like Dr. Dean Ornish and other so-called health
"experts" instilled in me about how dangerously unhealthy it is to consume it.
This fat phobia is arguably the single biggest contributor to the ongoing
obesity crisis our world faces today.

With that said, you and I both know fat consumption is a part of a healthy
lifestyle. There are just too many benefits to the body that come from the
consumption of fats and even saturated fats such as coconut oil, butter, lard,
nuts, seeds, and animal fat when it is combined with a restricted carbohydrate
intake.

An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.

Here are the actual numbers from the study:

- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%
- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%
- Eating 3X the saturated fat cut the amount in the blood in half

In an interview I conducted at my blog with Dr. Volek last year (here's the
link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html),
he said the conventional wisdom regarding fat, especially saturate fat, is dead
wrong while the significance of carbs is all but ignored by those who claim to
understand the metabolic response mechanism.

Here's what Dr. Volek said in my interview:

"Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."

Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.

Here's what she said:

"Eating fat (whatever kind) does not make you fat. It does not increase blood
stream saturated fat. Eating carbs does make you fat. Eating carbs does put
saturated fat in your blood stream."

To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.

And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.



TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc.

Have you encountered any phenomena of low-fiber on your approach?

JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html).

Fiber consumption is another one of those issues that not everyone who advocates
a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet.
Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).

As for consuming the highly-touted "healthy whole grain" cereals that you
mentioned, what a travesty that would be for people trying to manage their
weight and health. While the cereal manufacturers have had a heyday in their
marketing efforts promoting their whole grain content, it's all just a big fat
ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!

Many of these "healthy" cereals contain as many carbohydrates in a single bowl
without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.



TYP: 180 lbs of weight loss in your first year is absolutely astounding.

I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently?
How are your food choices today different from that first year?

JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!

It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).

There's a balance that people need to find for themselves and it's different for
all of us. I am one of the unlucky people who has to keep his carbohydrate
intake below 50g daily or I gain. It's just a fact of life that I've come to
grips with and realize is a necessity in order to manage my weight for the rest
of my life. But I wouldn't have it any other way!

Exercise was indeed a part of my low-carb weight loss success in 2004 as I
forced myself to do cardio every single day as a commitment to this journey. In
hindsight, that was probably not the best thing for me to do since the body has
a rather peculiar way of telling you it needs to wiggle and move spontaneously
on its own rather than forcing the issue. But I consider the exercise I did to
be such an integral part of my success that I dedicated an entire chapter of my
book to the subject.

Today, my daily cardio routine is out the window and I choose instead to engage
in activities outside the gym that let me burn calories and have some fun in the
process. I regularly play volleyball, basketball, and referee flag football at
my church which all give me quite a workout. I'm very physically active and fit
on my 6'3" body and just enjoy burning off all this excess energy that I have
been given since losing nearly have my weight! I do want to get into a little
more organized resistance training routine soon to try to shape and tone some
areas of my body that still show signs of that 410-pound man I used to be
(although the loose, hanging skin in my abdomen and inner thighs isn't going to
get any better with exercise since the elasticity has been ruined from being
stretched out so far). Here is a link to some posts and pictures I have written
about this subject:
http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.html

As for my food choices today compared to my weight loss year in 2004, they
haven't really changed a whole lot. This was a lifestyle change in every sense
of the phrase and I've learned to implement this way of eating into a permanent
and healthy diet that I can and will gladly live with forever and ever amen. I
probably eat more berries, melons, and nuts today than I did then, but otherwise
it's the identical diet.



TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years.

Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins?

JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone.

Nope, I sure don't!

Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.

Anyone interested in doing the low-carb lifestyle and needs help finding which
plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html).
It's the perfect overview of low-carb living with a comparison and recap of the
major plans.

THANK YOU again for allowing me to share my story with you and your readers, Dr.
Davis!

TYP: And thanks to you, Jimmy!

Mammogram of the heart

6. October 2007 William Davis (3)
Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.

First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).


















Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)



Both are also meant to be repeated periodically when normal as a surveillance process.

Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.

Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).

Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.

Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography.

CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries.

One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency.


Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.

Dr. Susie Rockway on conjugated linoleic acid (CLA)

5. October 2007 William Davis (7)
I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements.

A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives.

So I asked Dr. Rockway if she’d answer a few questions for us.






TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic?

Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!)

I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction!

Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health.

I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently.

So, how can you not be excited about this very bioactive molecule?




TYP: What are your specific areas of interest in nutrition and health?

Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health.

As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should.

Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there.

Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at.

Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research.



TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts?

Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.

When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood.

So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure.



TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years?

Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short!

We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!

One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education.

Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition.

See, it all comes back to CLA!


TYP: Thanks, Susie!

Which is better?

4. October 2007 William Davis (12)
If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:




Lipitor or a combination of fish oil, vitamin D, and elimination of wheat?


Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.

Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%.



A combination of fish oil, vitamin D, and elimination of wheat:

Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events.



On this combination, however, you also:

--Lose weight, often substantially.

--Improve bone health, esp. osteoporosis and arthritis.

--Reduce cancer risk from the vit D supplementation.

--Reduce risk of stroke.

--Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.

--Reduce winter blues.

--Experience more energy.

--Obtain increased clarity of thought (from elimination of wheat).

--Reduce blood pressure.


Oh, and there's no muscle aches.

Heart health for stupid people

4. October 2007 William Davis (3)
I'm kidding.

What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public.

A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:

Eat healthy--by eating a "balanced" diet low in saturated fat

Don't smoke

Exercise

Don't ignore chest pain symptoms or breathlessness

Know your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."


Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?

How about some real heart healthy advice:

Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.

If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).

Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.

Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.

Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.


That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice.

Money, money, money, money

3. October 2007 William Davis (3)
I've been asked the question numerous times:

Why aren't heart scans more popular?

First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is:

Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice?

That's easy: There's no money in it.


Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans.

This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer.

Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan.

With heart scans, there simply is no big payoff.

We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area.

The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.

I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money.

I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007.

The many faces of LDL

3. October 2007 William Davis (13)
Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.

As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:

LDL cholesterol: 96 mg/dl
This value puts Ginnie's LDL in the most favorable 25% in the country.


LDL particle number: 2140 nmol/l
This value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).

In addition, over 90% of Ginnie's LDL particles fell into the small class.

Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:

Apoprotein B somewhere in the 120 to 140 mg/dl range

Direct LDL 100-130 mg/dl range.


In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.

It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.

Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.

In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.

I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.

We will be working on some solutions in the coming months.

What does "Success" mean in the Track Your Plaque program?

2. October 2007 William Davis (11)
Say you begin with a CT heart scan score of 400.

You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns.

One year later, you get another heart scan. What score would constitute "success"?

With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed?

For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack.

You can read about how we view the various forms of success in the program by reading our latest Track Your Plaque Special Report, Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.
