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

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

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

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

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






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

Oatmeal: Good or bad?

11. March 2010 William Davis (67)

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

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

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

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

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

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

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

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

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

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

Mustard: Super health food?

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

Consider that mustard contains:

Vinegar

Turmeric

No appreciable sugar


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

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

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

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

Exercise and blood sugar

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

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

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

Think about it. Reduced blood sugar:

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

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

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

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

The most important weight loss tool

4. March 2010 William Davis (15)

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


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

A treadmill? 




A bicycle?






No. None of the above. 

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



Timing of blood sugars

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

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

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

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


From Juntunen et al 2002

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

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


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

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

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

Psssst . . . There's sugar in there

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

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

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

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

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

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

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


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

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

How low should blood sugar be?

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

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

Here's what they found:

Thyroid: Be a perfectionist

27. July 2009 William Davis (18)
If you'd like to reduce LDL cholesterol with nearly as much power as a statin drug, think thyroid.

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

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

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

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

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

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

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

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

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

Nutrition Syllogism

21. July 2009 William Davis (21)
What do you think of these chains of logic?

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



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


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

Try this one:

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


Ouch!

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

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

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

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

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

Is pomegranate juice healthy?

19. July 2009 William Davis (20)

Pomegranate juice, 8 oz:

Sugars, total 31.50 g

Sucrose 0.00 g

Glucose (dextrose) 15.64 g

Fructose 15.86 g




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

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


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

Honeydew melon:

Sugars, total 51.97 g

Sucrose 15.87 g

Glucose 17.15 g

Fructose 18.94 g

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

Do heart scans cause cancer?

14. July 2009 William Davis (3)
Another in a series of data extrapolations that attempt to predict long-term cancer risk from medical radiation exposure was published in the July 13, 2009 Archives of Internal Medicine, viewable here.

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

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

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

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

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

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

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


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




CT heart scans and radiation: The real story

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

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

Richard C. Semelka, MD
Professor and Vice Chairman, Department of Radiology
University of North Carolina–Chapel Hill



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

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

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

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


Just how much does medical radiation add to our exposure?

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

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

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

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

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

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

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

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


The media frenzy

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

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

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

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

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


Typical effective radiation dose values for common tests

Computed Tomography

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


Non-CT

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

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


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

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

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

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

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

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

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


Heart scans, CT coronary angiograms and the future

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

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

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

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

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

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

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

Goodbye, fructose

12. July 2009 William Davis (35)
A carefully-conducted study by a collaborative research group at University of California-Berkeley has finally closed the lid on the fuss over fructose vs. glucose and its purported adverse effects.

The study is published in its entirety here.

Compared to glucose, fructose induced:

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

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

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

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


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

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

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

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

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

The statin-free life

8. July 2009 William Davis (20)
Matt came to me because his doctor couldn't reduce his LDL cholesterol.

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

We started out by characterizing his lipoprotein patterns:

--LDL 155 mg/dl

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

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

--No lipoprotein(a)

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

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

I therefore asked Matt to:

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


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

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

--HDL 52 mg/dl a 24% increase

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

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

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

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

Creatine: Not just for muscle heads

5. July 2009 William Davis (29)
Even if you’re not interested in building big muscles like a bodybuilder, there are health benefits to increasing muscle mass: increased bone density, better balance, and fewer injuries. Greater muscle mass means higher metabolic rate, improved insulin responsiveness, lower blood sugar. The inevitable loss of muscle mass of aging can lead to frailty, an increasingly common situation for the elderly. Muscle loss be reversed, health improved as a result.

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

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

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

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

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

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

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

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

The ultimate “bioidentical” hormone

2. July 2009 William Davis (19)
There has been a lot of debate over whether or not “bio-identical” hormones, i.e., hormones identical to the human form, are superior to non-human forms dispensed by the drug industry.

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

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

That "bioidentical" hormone is pregnenolone.

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

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

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

Green coffee bean extract in AGF Factor I

7. June 2012 William Davis (16)
Track Your Plaque's new and proprietary formulation, AGF Factor I, is designed to to support a program to achieve low levels of endogenous glycation.

Endogenous glycation, discussed at length in a recent Track Your Plaque Special Report, makes LDL particles (especially small LDL particles) more prone to oxidation and thereby more atherogenic, i.e., more likely to contribute to atherosclerotic plaque. Endogenous glycation also exerts unhealthy effects on long-lived proteins in the body, such as the proteins in the lenses of your eyes (cataracts), the lining of arteries (hypertension), and the cartilage cells of joints (brittle cartilage and arthritis).

Endogenous glycation is reduced by slashing carbohydrates in the diet, especially the most offensive carbohydrates of all, the amylopectin A of wheat, sucrose, high-fructose corn syrup and other fructose sources. Endogenous glycation can also be blocked by using blockers of the glycation reaction, such as benfotiamine (lipid-soluble thiamine), pyridoxal-5'-phosphate (a form of vitamin B6 with greater glycation blocking effect), and chlorogenic acid from green coffee beans, all components of AGF Factor I, which also contains Portulaca oleracea (Portusana), or purslane, for reduction of glucose.

Green coffee bean extract, and thereby chlorogenic acid, is receiving increased attention, most recently due to a study demonstrating substantial weight loss with 750-1050 mg green coffee bean extract, providing approximately 325-500 mg chlorogenic acid per day. Participants lost 15.4 pounds over 8 weeks at the higher dose (500 mg chlorogenic acid per day), while participants lost 8.8 pounds over 8 weeks at the lower dose (325 mg chlorogenic acid per day).

AGF Factor I was not formulated for weight loss but, taken twice or three times per day, does indeed mimic the dose of chlorogenic acid from green coffee bean extract used in the weight loss study. If you wish to take advantage of this application of chlorogenic acid/green coffee bean extract, while also maximizing protection from endogenous glycation, our AGF Factor I is one excellent choice to do so.

Lessons learned from the 2012 Low-carb Cruise

14. May 2012 William Davis (13)
I just returned from Jimmy Moore's Low-carb Cruise, a 7-day excursion to Jamaica, Grand Cayman Island, and Cozumel aboard the Carnival Magic. During our 7 wonderful days, a number of authors and experts spoke, each offering their unique perspective on the low-carb world. The focus was the science, experience, and practical application of low-carbohydrate diets.

The event kicked off with a roast by Tom Naughton of Fat Head fame, who entertained with his insightful low-carb humor and predictions of my demise at the hands of Monsanto!

Among the most important lessons provided:

Dr. Andreas Eenfeldt of the Diet Doctor blog discussed how Sweden is leading the world as the nation with the most vigorous low-carbohydrate following, witnessing incredible weight loss and reversal of carbohydrate-related diseases way ahead of the U.S. experience. I spent several hours with Dr. Eenfeldt who, besides being an engaging speaker, is a new father and an all-around gentleman. At 6 ft, 7 inches, he also towered high above all of us.

Dr. Eric Westman of Duke University and author of The New Atkins for a New You, debunked low-carbohydrate myths, such as "low-carb diets are high-protein diets that make your kidneys explode."

Dr. John Briffa, creator of the popular blog, Dr. John Briffa: A Good Look at Good Health, and author of the wonderfully straightforward primer to low-carbohydrate eating, Escape the Diet Trap, stressed the importance of never allowing hunger to rule behavior. Dr. Briffa's serious writing tone conceals an incredible charm and wit that took me by surprise, having spent several thoroughly engaging hours over breakfast, lunch, and dinner with him over the week.

Fred Hahn, exercise expert, founder of Serious Strength and author of Slow Burn Fitness Revolution and Strong Kids, Healthy Kids, debunked a number of trendy exercise methods, boiling many of the purported benefits of exercise down to that of increased strength.

Dr. Chris Masterjohn of The Daily Lipid and supporter of the Weston A. Price Foundation program, provided a comprehensive overview of the data that fails to link saturated fat with heart disease. He also helped me understand the analytical techniques used in studies of advanced glycation end-products.

Denise Minger, brilliant young usurper of China Study dogma and blogger at Raw Foods SOS, proved an engaging speaker and a truly real person (since some critics of her analyses have actually questioned whether there was even such a person!). She also proved every bit as likable as she seems in her captivating blog discussions.

Dr. Jeff Volek, prolific researcher from University of Connecticut, author of over 200 studies validating low-carbohydrate diet effects, and author of the recently released book with Dr. Stephen Phinney, The Art and Science of Low Carbohydrate Living, debunked myths behind carbohydrate dependence and "loading" by athletes. He also talked about how assessing blood ketones may be the gold standard method to ensure low-grade ketosis on a long-term low-carb effort.

Over a bottle of wine, Jimmy Moore and I reminisced over how his modest start with no experience in blogging or media has now ballooned to an audience of over 100,000 readers/viewers.

All in all, Jimmy's Low-carb Cruise experience was worth every minute, with many wonderful lessons and memories!

Chili Sesame Crackers

3. May 2012 William Davis (0)
Looking for something hot and crunchy?

These chili sesame crackers are perfect for dipping into hummus or salsa. As written, the recipe yields a moderately spicy cracker that you can modify readily by increasing or decreasing quantities of cayenne pepper and Tabasco sauce.

This recipe uses sesame seeds as the "flour." Either brown sesame seeds or the lighter version work, though the lighter seeds yield a slightly less bitter flavor with the spices.

For ease of baking, a shallow baking pan measuring 11 x 17 inches works best, as it allows the batter to fill the pan and spread to a cracker thickness. With a smaller pan, you may have to bake in two batches.

Makes approximately 30 chips

2 cups raw sesame seeds
1 cup shredded Parmesan cheese
2 tablespoons extra-virgin olive oil
1 tablespoon chili powder
½ teaspoon cayenne pepper
2 teaspoons onion powder
1 teaspoon garlic powder
1 teaspoon dry mustard
1 teaspoon sea salt
1 teaspoon Tabasco sauce
1¼ cups water

Preheat oven to 350º F.

In food chopper or food processor, grind 1¼ cups sesame seeds to fine meal. Remove and place in large bowl.

Place shredded Parmesan cheese in food chopper or food processor and pulse briefly until reduced to granular consistency. Add to sesame seed meal and mix. Stir in olive oil.

Add remaining (unground) sesame seeds, chili powder, cayenne pepper, onion and garlic powder, mustard, sea salt and mix thoroughly. Add Tabasco sauce and water and mix. Add additional water, if necessary, one tablespoon at a time, to obtain a consistency similar to pancake batter.

Pour mixture into baking pan and smooth to fill pan and obtain a thickness of a cracker. If too thick, remove some batter and re-smooth. Optionally, roll a clean cylindrical glass or bottle over top to smooth and yield a consistent thickness.

Bake for 30 minutes or until edges browned and center firm. If a dry, extra crunchy cracker is designed, bake an additional 10-15 minutes at 250 degrees F.

Remove and allow to cool. Cut with pizza cutter to desired size.

Opiate of the masses

18. April 2012 William Davis (22)
Although it is a central premise of the whole Wheat Belly argument and the starting strategy in the New Track Your Plaque Diet, I fear that some people haven't fully gotten the message:

Modern wheat is an opiate.

And, of course, I don't mean that wheat is an opiate in the sense that you like it so much that you feel you are addicted. Wheat is truly addictive.

Wheat is addictive in the sense that it comes to dominate thoughts and behaviors. Wheat is addictive in the sense that, if you don't have any for several hours, you start to get nervous, foggy, tremulous, and start desperately seeking out another "hit" of crackers, bagels, or bread, even if it's the few stale 3-month old crackers at the bottom of the box. Wheat is addictive in the sense that there is a distinct withdrawal syndrome characterized by overwhelming fatigue, mental "fog," inability to exercise, even depression that lasts several days, occasionally several weeks. Wheat is addictive in the sense that the withdrawal process can be provoked by administering an opiate-blocking drug such as naloxone or naltrexone.

But the "high" of wheat is not like the high of heroine, morphine, or Oxycontin. This opiate, while it binds to the opiate receptors of the brain, doesn't make us high. It makes us hungry.

This is the effect exerted by gliadin, the protein in wheat that was inadvertently altered by geneticists in the 1970s during efforts to increase yield. Just a few shifts in amino acids and gliadin in modern high-yield, semi-dwarf wheat became a potent appetite stimulant.

Wheat stimulates appetite. Wheat stimulates calorie consumption: 440 more calories per day, 365 days per year, for every man, woman, and child. (440 calories per person per day is the average.) We experience this, sense the weight gain that is coming and we push our plate away, settle for smaller portions, increase exercise more and more . . . yet continue to gain, and gain, and gain. Ask your friends and neighbors who try to include more "healthy whole grains" in their diet. They exercise, eat a "well-balanced diet" . . . yet gained 10, 20, 30, 70 pounds over the past several years. Accuse your friends of drinking too much Coca Cola by the liter bottle, or being gluttonous at the all-you-can-eat buffet and you will likely receive a black eye. Many of these people are actually trying quite hard to control impulse, appetite, portion control, and weight, but are losing the battle with this appetite-stimulating opiate in wheat.

Ignorance of the gliadin effect of wheat is responsible for the idiocy that emits from the mouths of gastroenterologists like Dr. Peter Green of Columbia University who declares:

"We tell people we don't think a gluten-free diet is a very healthy diet . . . Gluten-free substitutes for food with gluten have added fat and sugar. Celiac patients often gain weight and their cholesterol levels go up. The bulk of the world is eating wheat. The bulk of people who are eating this are doing perfectly well unless they have celiac disease."

In the simple minded thinking of the gastroenterology and celiac world, if you don't have celiac disease, you should eat all the wheat you want . . . and never mind about the appetite-stimulating effects of gliadin, not to mention the intestinal disruption and leakiness generated by wheat lectins, or the high blood sugars and insulin of the amylopectin A of wheat, or the new allergies being generated by the new alpha amylases of modern wheat.

Jelly beans and ice cream

23. March 2012 William Davis (6)
What if I said: "Eliminate all wheat from your diet and replace it with all the jelly beans and ice cream you want."

That would be stupid, wouldn't it? Eliminate one rotten thing in diet--modern high-yield, semi-dwarf wheat products that stimulate appetite (via gliadin), send blood sugar through the roof (via amylopectin A), and disrupt the normal intestinal barriers to foreign substances (via the lectin, wheat germ agglutinin)--and replace it with something else that has its own set of problems, in this case sugary foods. How about a few other stupid replacements: Replace your drunken, foul-mouthed binges with wife beating? Replace cigarette smoking with excessive bourbon?

Sugary carbohydrate-rich foods like jelly beans and ice cream are not good for us because:

1) High blood sugar causes endogenous glycation, i.e, glucose modification of long-lived proteins in the body. Glycate the proteins in the lenses of your eyes, you get cataracts. Glycate cartilage proteins in the cartilage of your hips and knees, you get brittle cartilage that erodes and causes arthritis. Glycate structural proteins in your arteries and you get hypertension (stiff arteries) and atherosclerosis. Small LDL particles--the #1 cause of heart disease in the U.S. today--are both triggered by blood sugar rises and are 8-fold more prone to glycation (and thereby oxidation).

2) High blood sugar is inevitably accompanied by high blood insulin. Repetitive surges in insulin lead to <em>insulin resistance</em>, i.e., muscles, liver, and fat cells unresponsive to insulin. This forces your poor tired pancreas to produce even more insulin, which causes even more insulin resistance, and round and round in a vicious cycle. This leads to visceral fat accumulation (Jelly Bean Belly!), which is highly inflammatory, further worsening insulin resistance via various inflammatory mediators like tumor necrosis factor.

3) Sugary foods, i.e., sucrose- or high-fructose corn syrup-sweetened, are sources of fructose, a truly very, very bad sugar that is metabolized via a completely separate pathway from glucose. Fructose is 10-fold more likely to induce glycation of proteins than glucose. It also provokes a (delayed) rise in insulin resistance, accumulation of triglycerides, marked increase in formation of small LDL particles, and delayed postprandial (after-eating) clearance of the lipoprotein byproducts of meals, all of which leads to diabetes, hypertension, and atherosclerosis.

I think we can all agree that replacing wheat with jelly beans and ice cream is not a good solution. And, no, we shouldn't have drunken binges, wife beating, smoking or bourbon to excess. So why does the "gluten-free" community advocate replacing wheat with products made with:

rice starch, tapioca starch, potato starch, and cornstarch?

These powdered starches are among the few foods that increase blood sugar (and thereby provoke glycation and insulin) higher than even the amylopectin A of wheat! For instance, two slices of whole wheat bread typically increase blood sugar in a slender, non-diabetic person to around 170 mg/dl. Two slices of gluten-free, multigrain bread will increase blood sugar typically to 180-190 mg/dl.

The fatal flaw in thinking surrounding gluten-free junk carbohydrates is this: If a food lacks some undesirable ingredient, then it must be good. This is the same fatally flawed thinking that led people to believe, for instance, that Snack Well low-fat cookies were healthy: because they lacked fat. Or processed foods made with hydrogenated oils were healthy because they lacked saturated fat.

So gluten-free foods made with junk carbohydrates are good because they lack gluten? No. Gluten-free foods made with rice starch, tapioca starch, potato starch, and cornstarch are destructive foods that NOBODY should be eating.

This is why the recipes for muffins, cupcakes, cookies, etc. in this blog, the Track Your Plaque website, and the Track Your Plaque Cookbook are wheat- and gluten-free and free of gluten-free junk carbohydrates. And put that bottle of Jim Beam down!

Diet by LDL

7. March 2012 William Davis (0)
Conventional notions of heart healthy diets, such as that advocated by the American Heart Association, are largely based on observations of total and LDL cholesterol.

So, cut the saturated fat in the diet, cut the overall fat content, and replace them with polyunsaturated oils like safflower, corn, and vegetable oils and increase consumption of whole grains and total and LDL cholesterol show a modest downturn. Thus, diets like the American Heart Association Total Lifestyle Change approach advocate limiting total fat to no more 25 to 35% of calories and saturated fat to no more than 7% of calories.

Orange Cream Cookies

5. March 2012 William Davis (5)
If you loved Creamsicles as a kid, you'll love these Orange Cream Cookies. (Sorry, no photo: We ate them up before I realized we hadn't taken the photo. And, worse, we did it twice!)

Ingredients:
2 cups almond meal
2 tablespoons coconut flour
1 teaspoon baking soda
½ teaspoon sea salt
¼ cup golden raisins
½ cup chopped pecans
Sweetener equivalent to 1 cup sugar
2 tablespoons finely-grated orange rind
1 large egg
2 tablespoons coconut oil, melted
½ cup whipping cream (or coconut milk)
1 tablespoon vanilla extract

Preheat oven to 350º F.

Combine almond meal, coconut flour, baking soda, salt, raisins, pecans, sweetener and orange zest in bowl and mix.

In separate bowl, whisk egg, then add coconut oil, whipping cream, vanilla extract and mix together. Pour wet mix into dry and blend by hand thoroughly.

Spoon onto parchment paper-lined baking pan (or oiled pan) and flatten with spoon to ½-¾ inch thickness. Bake for 20-25 minutes or until toothpick withdraws dry.

Why are heart attacks still happening?

4. March 2012 William Davis (10)
I'm a cardiologist. I see patients with heart disease in the form of coronary artery disease every day.

These are people who have undergone bypass surgery, received one or more stents or undergone other forms of angioplasty, have survived heart attacks or sudden cardiac death, or have high heart scan scores. In short, I see patients every day who are at high-risk for heart attack and death from heart disease.

But I see virtually no heart attacks. And nobody is dying from heart disease. (I'm referring to the people who follow the strategies I advocate, not the guy who thinks that smoking a pack of cigarettes a day is still okay, or the woman who thinks the diet is unnecessary because she's slender.)

Two high-profile deaths from heart attacks occurred this week:

Davy Jones--The iconic singer from the 1960s pop group, the Monkees, suffered sudden cardiac death after a large heart attack, just hours after experiencing chest pain.

Andrew Breitbart--The conservative blogger and controversy-generating media personality suffered what was believed to be sudden cardiac death while walking.

It's a darn shame and it shouldn't happen. The tools to identify the potential for heart attack are available, inexpensive, and simple. The strategies to reduce, even eliminate, risk are likewise available, inexpensive, and cultivate overall health.

The followers of the Track Your Plaque program who

1) get a heart scan that yields a coronary calcium score (for long-term tracking purposes)
2) identify the causes such as small LDL particles, lipoprotein(a), vitamin D deficiency, and thyroid dysfunction
3) correct the causes

enjoy virtual elimination of risk.

My letter to the Wall Street Journal: It's NOT just about gluten

8. February 2012 William Davis (7)
The Wall Street Journal carried this report of a new proposed classification of the various forms of gluten sensitivity: New Guide to Who Really Shouldn't Eat Gluten

This represents progress. Progress in understanding of wheat-related illnesses, as well as progress in spreading the word that there is a lot more to wheat-intolerance than celiac disease. But, as I mention in the letter, it falls desperately short on several crucial issues.

Ms. Beck--

Thank you for writing the wonderful article on gluten sensitivity.

I'd like to bring several issues to your attention, as they are often neglected
in discussions of "gluten sensitivity":

1) The gliadin protein of wheat has been modified by geneticists through their
work to increase yield. This work, performed mostly in the 1970s, yielded a form
of gliadin that is several amino acids different, but increased the
appetite-stimulating properties of wheat. Modern wheat, a high-yield, semi-dwarf
strain (not the 4 1/2-foot tall "amber waves of grain" everyone thinks of) is
now, in effect, an appetite-stimulant that increases calorie intake 400 calories
per day. This form of gliadin is also the likely explanation for the surge in
behavioral struggles in children with autism and ADHD.
2) The amylopectin A of wheat is the underlying explanation for why two slices
of whole wheat bread raise blood sugar higher than 6 teaspoons of table sugar or
many candy bars. It is unique and highly digestible by the enzyme amylase.
Incredibly, the high glycemic index of whole wheat is simply ignored, despite
being listed at the top of all tables of glycemic index.
3) The lectins of wheat may underlie the increase in multiple autoimmune and
inflammatory diseases in Americans, especially rheumatoid arthritis and
inflammatory bowel diseases (ulcerative colitis, Crohn's).

In other words, if someone is not gluten-sensitive, they may still remain
sensitive to the many non-gluten aspects of modern high-yield semi-dwarf wheat,
such as appetite-stimulation and mental "fog," joint pains in the hands, leg
edema, or the many rashes and skin disorders. This represents one of the most
important examples of the widespread unintended effects of modern agricultural
genetics and agribusiness.

Why health care costs are ballooning

28. March 2008 William Davis (7)
Have you ever wondered to what degree health care is driven by a profit motive?

A doctor advises you to undergo a procedure. Is that advice motivated solely by concern for your health and welfare? Or, does the generous financial compensation peculiar to procedures bias your doctor’s decision?

The billboard on the highway advertises a hospital heart program. Is it meant to raise awareness of lifesaving services? Or, is it the same as an ad for a casino or hotel chain, a marketing tool for generating business?

At one time or another, we’ve probably all shared a suspicion that healthcare is occasionally motivated by money: over-priced prescription drugs, hospitals charging higher prices to the uninsured, the three-minute doctor’s visit for $200.

Direct-to-consumer drug advertising has brought aggressive drug sales tactics front and center to the public’s attention. “Ask your doctor about . . .” is the mantra of countless 30-second spots appearing several times an hour on national television. Direct-to-consumer drug advertising has provided the American public with a $4.5 billion reminder that there’s money to be made in the world of prescription drugs (U.S. Government Accountability Office). And there’s certainly a load of money to be made. A 2003 Harvard and Massachusetts Institute of Technology study showed that, of every dollar spent on consumer drug advertising, $4.20 was recovered through increased sales (Impact of Direct-to-Consumer Advertising on Prescription Drug Spending; Henry J Kaiser Family Foundation). A $53,000 ad run three times during the Oprah Winfrey Show is money well invested for a drug manufacturer.

The knotty issue of medical errors has recently captured attention. Unintentional medical errors—-nurses administering the wrong medication, doctor misdiagnoses or amputating the wrong leg, unrecognized medication interactions—-are an estimated $29 billion headache. Former Secretary of Health and Human Services, Tommy Thompson, reported that up to 98,000 lives are lost every year as a result of errors in healthcare delivery.

No doubt, these are all enormous problems that plague our healthcare system.

But I am going to make the case for a much larger problem. The magnitude of this problem dwarfs that of medical errors. It’s not an issue of neglect, nor is it committed in error. It is built on intentionally committed acts, systematically conducted on a massive scale, and sustained by the participation of many. It is a plague of unprecedented proportions on the health care system. It requires the willing participation of parties at multiple levels, from lone medical practitioners, to hospitals, to multi-billion dollar medical device and drug manufacturers, even to institutions like the FDA and American Heart Association.

The problem is the bizarre situation that has evolved in health care for the heart. I specify health care for the heart, not heart disease, because actual disease is not always part of the equation. Astonishingly, much of the inflated cost of heart care is based on the feared specter of heart disease, the implied threat of heart disease, the possibility, sometimes vanishingly remote, of heart disease based on some harbinger of risk. Sometimes the disease itself is nowhere in sight.

The system thrives on a culture of fear, an open ticket to over-testing and profligate spending. Ads cleverly admonish you to “Do it for your family”. Nuclear stress testing alone generates $18 billion of costs. Yet this test is normal in 80% of people tested. Worse, the 20% of “abnormal” stress test results are not always indicative of genuine disease, they are “false positive,” and are a big part of the reason that 30% of heart catheterizations fail to show disease. “My arteries checked out okay!” relieved patients will declare?-but there may have been no reason to have pursued a costly test like catheterization in the first place. But the system makes far better sense when you understand that nuclear stress tests and heart catheterizations are the bread and butter of cardiologists and hospitals, and the ticket to more financially rewarding procedures.

This approach evolved in the 1960s, when coronary heart disease itself was impossibly difficult to diagnose until a catastrophe like heart attack declared itself. But in the 21st century, coronary heart disease is easily, inexpensively, and safely detectable, decades before heart attack risk looms over your life. Yet murky, risk-based tests like stress tests and cholesterol testing continue to dominate the practice of “heart disease detection” in real-life practice.

Make no mistake: This problem is huge. The cardiovascular health care system has mushroomed into a gargantuan profit-generating mechanism, far larger than is required to deliver essential heart care. In 2003, over $431.8 billion was spent in the U.S. on cardiovascular health care, $151.6 of this on coronary disease alone (American Heart Association, Heart Disease and Stroke Statistics—2007 Update). The U.S. Department of Health and Human Services projects that total health care spending will double to $3.6 trillion by 2014, consuming 18.7 percent of the nation's economy, much of the increase due to expanding cardiovascular costs.

Most tragically, the system has grown through the exploitation of trust. The faith we have in doctors, hospitals, and the institutions and people associated with healthcare has been subverted into the service of profit. Many practitioners and institutions have chosen to operate under the guise of doing good but instead capitalize on the public’s willingness to accept as fact the need for a major heart procedure and all its associated costly trappings.

Heart scans know no race

27. March 2008 William Davis (0)
The New England Journal of Medicine just published a new analysis of the Multi-Ethnic Study of Atherosclerosis (MESA) database authored by Dr. Robert Detrano of University of California-Irvine.

As we would expect, the study confirmed the ability of heart scans and coronary calcium scoring to predict heart attack. This study is unique, hovever, in including Hispanics, Chinese Americans, and African Americans in its 6722 participants.

The analysis confirmed that coronary calcium scores yielded similar information, regardless of race. It confirmed that people with a zero heart scan score had a nearly zero risk of cardiovascular events; it also confirmed that higher scores (e.g., >300) yielded much greater risk over the 4 years of observation: 7.73-fold greater risk for people with scores 101-300; 9.67-fold greater for scores >300.

One of the media reports on the study can be viewed on HeartWire

Bill Sardi's Knowledge of Health website and blog also has an insightful commentary.

To those of us who have used heart scans in thousands of people, the MESA results come as no surprise, having seen these phenomena played out every day in real life. Although similar results have been previously shown in a number of other smaller studies, Detrano's analysis of MESA does serve to further validate these concepts. It also serves to deliver the message more broadly into the mainstream media message.

No surprise whatsoever: Coronary calcium scores obtained through heart scans represent a measure of the disease--coronary atherosclerosis--itself. It is not a risk factor that may or may not be associated with development of coronary atherosclerosis. Thus, when heart scan scores are held up in comparison the cholesterol, LDL cholesterol, c-reactive protein, or any other risk measure, heart scan scores outshine all these measures by enormous margins as predictors of your future.

Want to know what your uncorrected heart disease future could be? Consult your heart scan score. Not your cholesterol panel.

Heart Scan Frustration

27. March 2008 William Davis (4)
Ideally, you get a heart scan and your doctor sits down with you and provides a rational, insightful discussion on what the results mean.

Is heart attack in your future? If so, when? Are blockages present? What is the role of other tests like stress tests and heart catheterizations? Do CT coronary angiograms add any important information? What is the role of cholesterol? Can diet or nutritional supplements impact on heart scan score?

But what happens if you are unable to get the answers you desire? What if you get brusque responses, or your doctor just doesn't know? Or what if there is a clear conflict of interest or the possibility of financially-tainted advice? ("You need a heart catheterization right away or you'll die of a heart attack!")

One example of this process was posted by a frustrated Member of Track Your Plaque who found that answers were virtually unobtainable from his/her doctors:

I underwent a heart scan a few weeks ago, based on a recommendation from a doctor. I assumed that, since I was paying for it, and I requested it, the results would be fully explained to me.

Late on a Friday afternoon, the radiologist who intrepreted it called me and said I would be receiving a report, and so would the doctor. I asked that she explain them to me. She said their policy was to give the report to the doctor and let him explain them. She did say I was in the 90th percentile for my age--and that 10% had a worse score. I asked where do we go from here, and she said, if you're not having symptoms, maybe lifestyle changes, but YOUR DOCTOR will let you know. I asked for a copy of the films and reports, and was told YOUR DOCTOR can request them. I called back a little later and she was gone. It was starting to sink in that I must have a terrible score. In the meantime, I did what I should have done before I went for the scan---looked up information on the internet, and read about calcium scoring. This website [Track Your Plaque] hadn't showed up in my Google search, so a lot of the information was useless.

I did manage to get the score of 186, with the breakdown per artery from someone at the clinic, but only after I insisted I paid for the test, I have a right to the information. 'Course having a score per artery didn't really help---what did it mean? ie: if a 72, how did that correlate to any blockages? Was it a big lump...or spread along the wall throughout the artery.

I had an appt. the following Tuesday with THE DOCTOR---a very busy doctor. After an hour and 1/2 wait in a crowded waiting room, I got to see him. We discussed briefly another issue, and he started walking out. I followed him out and said I wanted my full l5 minutes of time allotted in their scheduling, which seemed to irritate him.

I followed him into his office and said, WHAT ABOUT THE HEART SCAN? What do the numbers mean? He responded that he didn't know, he'd have to see the films, but don't worry--you're probably ok, and I should get a thallium stress test anyway. He said he couldn't intrepret the numbers, or give an opinion on where the plaque was or how it was configured.

I then went to the interventional cardiologist that afternoon and the thallium stress test was scheduled. I asked about the HEART SCAN, and again, no acknowledgment. I asked if he would get the films and explain the results, and again no acknowledment as he was walking out the door.

After this lengthy saga.....MY QUESTION IS....since this is a test you can order yourself (literature at center made mention of the tests you can get without a doctors request)......WHO IS THEIR FIDUCIARY RESPONSIBILITY TO WHEN IT COMES TO EXPLAINING THE RESULTS?

I learned more on this website [Track Your Plaque], and the emailed book then I did dealing with two doctors and the center itself. Thinking back, there was nothing but a brochure on the test at the center. No "Track your Plaque" stuff.



Day 2
I called the scanning center and relayed my dilemma. I was put in touch with another radiologist--a very informative one, who appeared passionate about heart scans as a preventive test. He compared them to mammograms. He hadn't heard about the "Track Your Plaque" program but was going to check it out. He said people varied in their responses to the test results, as well as doctors/cardiologists as to the next step. (ie: lifestyle changes..the next test, etc). He seemed to feel blockages of more than 50% for many cardiologists would indicated angioplasty and stenting.

I'm going back to review the films with him later this week. He wasn't that concerned with the 101 reading on the right artery. The 72 on the left he had concerns with and indicated the CAT test [CT angiography] would offer more as far as how much was there, and approx. blockage, and could be a baseline to compare to in the future. He said some cardiologists would go right to angioplasty...some to a CAT which is more conservative...some might watch and encourage lifestyle changes. He said the Heart Scan doesn't show soft plaque. He also said the internist who referred me was one of only a few in the city that felt strongly about the heart scan---and probably used it to take further action via a referral, and just didn't have time to discuss it, with the way medicine is run these days.



This Member's frustrated post pretty much sums it up:

1) Doctors don't seem to have the time nor motivation to be bothered about offering advice that leads to prevention of disease.

2) The tendency is to always ask, "Are heart procedures necessary?", not "How did this happen?" or "What can we do about this to keep it from getting worse?" How about diet, supplements, and other tools to use at home?

The obvious uneasiness of the radiologist, the last physician this Member spoke with, can just as easily lead to boneheaded advice: Maybe getting a stent isn't such a bad idea. Maybe a CT angiogram is an absolute necessity.

I hear comments like this every day. It is the reason why I continue to plug away at this program and try to set things straight.

By the way, subscribers to our Track Your Plaque Newsletter just heard about our latest success story, Roy, who dropped his heart scan score over 500 points. If you are yet not a newsletter subscriber, click here.

Dr. Nieca Goldberg and heart healthy

23. March 2008 William Davis (1)

In January, 2007, $11.6 billion (2006 net sales) cereal manufacturing giant General Mills rolled out three million boxes of Wheat Chex and Multi-Bran Chex, each boasting a picture of cardiologist, Dr. Nieca Goldberg's face on the box.

Dr. Goldberg has been a frequent national spokeswoman for the American Heart Association (AHA). In a media interview, American Heart Association President, Dr. Alice Jacobs, stated that she supports Dr. Goldberg's work with the General Mills’ products. "The AHA is always in favor of educating the public on how to make heart-healthy lifestyle choices." Dr. Jacobs added that the AHA doesn't consider Goldberg's appearance on the cereal boxes ‘an endorsement’ of the products. "The content on the box is basic heart health information," she said.

Putting images of someone like Dr. Goldberg on cereal boxes appeals to a certain audience, mothers worried about health in this instance. Manufacturers recognize that the perceptions of their food need to be created and nurtured.

Eerily reminiscent of tobacco company tactics of the 20th century? Recall the Brown and Williamson claim that Kool cigarettes keep the head clear and provide extra protection against colds? Lucky Strike, Chesterfield, and Camels all promoted the health benefits of cigarettes, including prominent endorsements by physicians.

How about Philip Morris’ ads for Virginia Slims cigarettes: "You've come a long way, baby"? Interestingly, food manufacturing behemoths Kraft and Nabisco were both majority-owned by Philip Morris, now renamed Altria.

Take a look at the composition of these two "heart healthy" breakfast cereals endorsed by Dr. Nieca Goldberg and the American Heart Association:



























Products like this:

--Make people fat--abdominal fat (wheat belly)
--Reduce HDL cholesterol
--Raise triglycerides
--Dramatically increase small LDL
--Increase inflammatory responses
--Increase blood pressure
--Increase likelihood of diabetes

These products are sugar and sugar-equivalents with a little fiber thrown in and a lot of marketing propaganda, aided and abetted by the misguided antics of the American Heart Association and Dr. Goldberg. It's hard to believe that Dr. Goldberg would sell her soul on something so knuckleheaded for a moment of notoriety.

As I've often said, if a product bears the AHA Check Mark of approval, be sure not to buy it.

Bait and switch

23. March 2008 William Davis (5)
“When banks compete, you win.”

The TV ad opens with a 60-something man sitting in his living room, talking to a three-piece suit-clad, 30-something banker. The older man is explaining to the dismayed younger man why he’s going to use Lending Tree loan service for a home loan.

“But Dad, I’m you’re son!” the younger whines.

Many of Lending Tree’s clients have collaborated in filing a multi-million dollar class action suit against the company, claiming “bait and switch” tactics. They claim that home buyers are lured by low interest rates or low closing costs on a home loan. Once the buyer concludes the hassle of filling out numerous forms, the suit accuses Lending Tree of making a switch to a costlier loan.

Bait and switch is among the oldest con games around. If you’ve ever bought a car from a car dealer, chances are you’ve had your own little brush with this deception. The ad promises the SUV you’ve wanted for only $299 per month. Only, once you get there, the salesman informs you that only a limited number of special deals were available and they’ve run out. But he’s still got a really good deal right over here!

Most of us recognize that we’ve been hookwinked. Yet we still go along and buy a car from the dealer.

What if it’s not a sleazy salesman behind the pitch, but a physician. If it’s hard to resist the sales pitch at the car dealership, it can be near impossible to ignore the advice of your doctor. But the truth is often loud and clear: in many instances, it is a genuine, bona fide, and fully-certified scam.

Among the most common bait-and-switch heart scams: Your cholesterol is high. The sequence of subsequent testing is well-rehearsed. “Gee, Bob, I’m worried about your risk for heart disease. Let’s schedule you for a nuclear stress test.” The stress test, like 20% or more of them, is “falsely positive,” meaning abnormal even though there’s nothing wrong with you. Another 30% are equivocal, not clearly abnormal but also not clearly normal. Now up to 50% of people tested “need” a heart catheterization in the hospital to clarify this frightening uncertainty. You might end up with a stent or two, even bypass surgery. Your simple $20 cholesterol panel has metamorphosed into $100,000 in hospital procedures. That familiar sequence is followed thousands of times, seven days a week, 365 days a year.

There are times when these heart tests are valuable and provide meaningful answers. Then there's the other half of the time when they provide murky information that can be used for a practitioner's economic advantage.

A fictional tale of medical economics in heart disease

23. March 2008 William Davis (2)
Dr. Robert Connors is the hospital’s most prized cardiologist.

Practically a fixture in the cath lab, he generates more revenues for the hospital than any of his colleagues. Last year alone, he performed over 1500 procedures, bringing in $18 million dollars to the cath lab, $27 million to the hospital. Dr. Connors is very good at what he does: 55-years old, he has been involved in high-tech heart care since the “early days,” 25 years ago, when hospital procedures really began to take off.

Over his career, he has personally performed over 25,000 heart procedures and has built a reputation as a skilled operator of complex coronary procedures. Because of his skills, he enjoys a vigorous flow of referrals for procedures from dozens of primary care physicians. His skill has also earned him referrals from cardiologist colleagues who seek his abilities for difficult cases.

On any day, Dr. Connors typically schedules up to 12 procedures. His entire day is spent in the cath lab, usually from 7 am until 6 pm. He meets many patients for the first time on the catheterization laboratory table as staff shave their groin, preparing for the procedure. Much of the procedure itself is not even performed by Dr. Connors, but by one or another cardiologists-in-training, a “fellow,” or member of the fellowship the hospital proudly maintains as a clinical teaching institution. Nor will Dr. Connors talk to most patients at the close of the procedure. He leaves that to either the fellow or a nurse. Dr. Connors views himself as a procedural specialist, not someone who has to take care of patients. He gave up seeing patients in his office over 10 years ago.

Dr. Connors’ procedural enthusiasm gained him the attention of drug and medical device manufacturers. Because Dr. Connors lectures widely and advises colleagues, his comments can dramatically alter perceptions of the value of a technology. He has, on many occasions, catapulted an unpopular device to most-asked-for among colleagues, bringing millions of dollars in revenues to the manufacturer. One particularly lucrative arrangement he made around 10 years ago involved a “closure” device, a $400 single-use plug used to close the access site made during heart catheterizations. By swaying his colleagues at _______ Hospital, 50 orders per day (one per procedure) tallied $20,000 every day, $7.1 million dollars per year for the manufacturer. Although he’d used other devices on the market, the 5,000 shares of stock he was offered encouraged him to issue glowing comments to colleagues on the superiority of this specific brand of closure device. Now over 90% of all catheterizations at _______ Hospital conclude with the device manufactured by the company in which Dr. Connors maintains partial ownership.

Negative comments, on the other hand, topple other products when Dr. Connors sees fit to pan them. For this reason, device and drug manufacturers run straight to Dr. Connors to gain his good graces as soon as possible after a product is released into the market. Because the competition is just as likely to do the same, it has often come down to a bidding war, the company providing the most lucrative arrangement most likely to win.

Thus, Dr. Connors proudly boasts of how many times he has flown to Hawaii, Europe, and other exotic locations at industry expense. He also boasts of how, for $100,000 paid to him for a “consulting fee,” he can overturn the choice of products lining hospital shelves. As the hospital’s annual budget for coronary devices will top $84,000,000 this year, device manufacturers regard the sum paid Connors as a profitable investment.

Despite his lofty status in the hospital, Dr. Connors has long expressed a love-hate relationship with ________ Hospital. While he enjoys his work and has made a more than comfortable income, he has long felt that the hospital administration didn’t truly appreciate his contributions. Five years ago, he therefore demanded that he be made “Director of Research.” After all, he had hired a nurse to help him coordinate enrollment of patients into several device trials brought to him by medical device manufacturers. When he encountered an initial lukewarm response from hospital administrators, he threatened to take his “business” elsewhere to a competing hospital. Hospital administrators gave in. They provided him with the title he wanted, along with $100,000 annual “stipend.”

Just fiction? Make no bones about it: Cardiac care is business, big business. And there's money to be made, lots of it.

Disease engineering

21. March 2008 William Davis (10)
Imagine you catch pneumonia.

You have a fever of 103, you’re coughing up thick, yellow sputum. Breathing is getting difficult. You hobble to the doctor, who then fails to prescribe you antibiotics. You get some kind of explanation about unnecessary exposure to antibiotics to avoid creating resistant organisms, yadda yadda. So you make do with some Tylenol®, cough syrup, and resign yourself to a few lousy days of suffering.

Five days into your illness, you’ve not shown up for work, you’re having trouble breathing, and you’re getting delirious. An emergency trip to the hospital follows, where a bronchoscopy is performed (an imaging scope threaded down your airway) and organisms recovered for diagnosis. You’re put on a ventilator through a tube in your throat to support your breathing and treated with intravenous antibiotics. Delayed treatment permits infection to escape into the fluid around your lungs, creating an “empyema,” an extension of the infection that requires insertion of a tube into your chest through an incision to drain the infection. You require feeding through a tube in your nose, since the ventilator prevents you from eating through your mouth. After 10 days, several healing incisions, and a hospital bill totaling $75,000, you’re discharged only to be face eights weeks of rehabilitation because of the extreme toll your illness extracted. Your doctor also advises you that, given the damage incurred to your lungs and airways, you will be prone to more lung infections in the future, and similar situations could recur whenever a cold or virus comes long.

A disease treatable by taking a 10-day, $20 course of oral antibiotics at home was converted into a lengthy hospital stay that generated extravagant professional fees, testing, and costly supportive care. You’ve lost several weeks of income. You’re weak and demoralized, frightened that the next flu or virus could mean another trip to the hospital. You are susceptible to repeated bouts of such episodes in future.

Such a scenario would be unimaginable with a common infection like pneumonia, or it would be grounds for filing a malpractice lawsuit. But, as horrific as it sounds in another sphere of health care, it is, in effect, analogous to how heart disease is managed in current medical practice.

First, you’re permitted to develop the condition. It may require years of ignoring telltale signs, it may require your unwitting participation in unhealthy lifestyle practices, like low-fat diets, "eat more whole grains," and "know your numbers."

It then eventuates in some catastrophe like heart attack or similar unstable heart situation, at which point you no longer have a choice but to submit to major heart procedures. That’s when you receive your heart catheterization, coronary stents, bypass, defibrillators, etc.

Of course, none of these procedural treatments cures the disease, no more than a Band Aid® heals the gash in your leg. The conditions that were present that created heart disease continue, allowing a progressive disease to worsen. At some point, you will need to return to the hospital for yet more procedures when trouble recurs, which it inevitably does.

A coronary bypass operation costs, on average $67,823. That includes the cost for the heart catheterization performed by a cardiologist to provide the surgical roadmap of your coronary arteries, the surgeon’s fees, the hospital charges. If there are any complications of your procedure, then your hospital bill may total a substantially higher figure.

$67,823 is just the upfront financial pay-off. Over the long run, your life is actually worth far more to the cardiovascular health care system because no heart procedure yields a permanent fix. In fact, repeated reliance on the system is the rule.

In fact, over 90% of people who enter the American cardiovascular health care system do so through a revolving door of multiple procedures over several years. It is truly a rare person, for instance, who undergoes a coronary bypass operation, never to be seen again the wards of the hospital because he remains healthy and free of catastrophe. A much more familiar scenario is the man or woman who undergoes two or three heart catheterizations, receives 3,4, or 6 stents, followed a few years later by a heart bypass, pacemaker, defibrillator, as well as the tests performed for catastrophe management, such as nuclear stress test, echocardiogram, laboratory blood analysis, and consultation with several specialists. The total revenue opportunity is many-fold higher than the initial 60-some thousand dollars, but instead totals hundreds of thousands of dollars per person.

A heart attack alone is a $100,000 revenue opportunity (Agency for Healthcare Research and Quality, 2004).

Of all coronary bypass procedures performed, 25% are “re-do’s”, or bypasses in people who’ve had a previous one, two, or three bypass procedures.

Perhaps it's excessively cynical to label it "disease engineering." But, whether from benign neglect or purposeful failure to diagnose, the fact remains: Heart disease is, all too often by the standard path, undiagnosed and neglected for years until the procedural payoff strikes.

Free checking, auto shows, low-cost hotel rooms, and bypass surgery

20. March 2008 William Davis (3)
Of the three major highways that lace the city of Milwaukee, there are at least five, and sometimes as many as ten, billboards that prominently feature one hospital heart program or another.

The passing of former First Lady, Ladybird Johnson in July, 2007, reminds us that, just 30 years ago, billboards were a far more common feature (many called them eyesores), proliferating like a dense forest of trees competing for a sliver of sunlight. Ladybird Johnson played a pivotal role in helping to dramatically reduce the number of billboards permissible on the nation’s highways. Of the relative few that remain today, a premium must be paid to post an advertisement. It costs several thousands dollars every month to maintain these highway commercials. But it’s not just an expense; it’s an investment.

The tens of thousands of eyes that view these billboards every day are potential customers, insured Milwaukeeans who carry health insurance and represent a major heart procedure just waiting to happen. They “need” to be directed to the right place. The billboards don’t feature health and wellness, heart disease prevention, or nutritional advice. They feature surgeons proudly wearing scrubs and masks, nurses, and declarations of the advantages of each hospital program. In effect, they invite you to have your heart attack, heart catheterization, bypass surgery, or other major heart procedure at their hospital. High-tech, high-ticket hospital heart care has become the subject of mainstream marketing, the stuff of flyers, brochures, and billboards.

The excesses of “big heart disease” have created a system that makes procedural heart disease “repair” far more profitable than heart disease prevention. Unfortunately, “repair” has disastrous financial, physical, and emotional consequences for everyone save the “repairman.”

While great good has been achieved by the American health care system, this gargantuan and inefficient system has also cultivated a culture of excess that has made many of its participants—physicians, hospitals, drug and device manufacturers—rich. And at our expense.

This approach was, to a degree, justifiable at a time when nothing better was available. But that's no longer true.

No-flush niacin kills

20. March 2008 William Davis (18)
Gwen was miserable and defeated.

No wonder. After a bypass operation failed just 12 months earlier with closure of 3 out of 4 bypass grafts, she has since undergone 9 heart catheterization procedures and received umpteen stents. She presented to me for an opinion on why she had such aggressive coronary disease (despite Lipitor).

No surprise, several new causes of heart disease were identified, including a very severe small LDL pattern: 100% of LDL particles were small.

Given her stormy procedural history, I urged Gwen to immediately drop all processed carbohydrates from her diet, including any food made from wheat or corn starch. (She and her husband were shocked by this, by the way, since she'd been urged repeatedly to increase her whole grains by the hospital dietitians.) I also urged her to begin to lose the 30 lbs of weight that she'd gained following the hospital dietitians' advice. She also added fish oil at a higher-than-usual dose.

I asked her to add niacin, among our most effective agents for reduction of small LDL particles, not to mention reduction of the likelihood of future cardiovascular events.

Although I instructed Gwen on where and how to obtain niacin, she went to a health food store and bought "no-flush niacin," or inositol hexaniacinate. She was curious why she experienced none of the hot flush I told her about.

When she came back to the office some weeks later to review her treatment program, she told me that chest pains had returned. On questioning her about what she had changed specifically, the problem became clear: She'd been taking no-flush niacin, rather than the Slo-Niacin I had recommended.

What is no-flush niacin? It is inositol hexaniacinate, a molecule that indeed carries six niacin molecules attached to an inositol backbone. Unfortunately, it exerts virtually no effect in humans. It is a scam. Though I love nutritional supplements in general, it pains me to know that supplement distributors and health food stores persist in selling this outright scam product that not only fails to exert any of the benefits of real niacin, it also puts people like Gwen in real danger because of its failure to provide the effects she needed.

So, if niacin saves lives, no-flush niacin in effect could kill you. Avoid this scam like the plague.

No-flush niacin does not work. Period.


Disclosure: I have no financial or other relationship with Upsher Smith, the manufacturer of Slo-Niacin.

Breakfast comments

19. March 2008 William Davis (7)
I received some wonderful comments to the What's for breakfast blog post.

Even though comments are viewable by clicking on them, I wanted to be sure these were readily visible, since they were so helpful and augmented the few suggestions I made. I'm impressed with the variety of foods people are willing to introduce into breakfast, particularly foods not traditionally thought to be part of standard American breakfast choices.




I normally eat a handful of almonds, some raw cashews, and occasionally an orange for breakfast. I used to eat cheese with breakfast also, but found once I began eating cheese it was hard for me to stop at one or two pieces.

My favorite breakfast is often left over Thai curry. I omit the rice. I also like making a thai omelet which is simply 2 eggs and some fish sauce and water and serving it with Sirachi sauce or Thai peanut sauce. It is street vendor food in Thailand I hear. Here's a recipe.

I find left over dinners are quite wonderful for breakfast. You just have to get past this notion that you have to eat certain foods at certain times in the day. Where'd that idea come from anyway?

I’ve tried eating oatmeal throughout my life, really wanting to like it. Until now the mere taste or smell of it made my stomach queasy. The key for me was toasting the oatmeal. Here’s what I generally do:

For Steel-cut oatmeal with the taste and texture of rice pudding-

In a frypan:
Toss 1 TBS of butter or so into a hot pan.
Add 1 cup of steel-cut oatmeal until toasted.
--few minutes
In a saucepan:
Boil 2-1/2 cups water
Add 1 cinnamon stick (or equivalent)
Add toasted Steel-cut oatmeal and cook for 15-20 minutes or so

Add 1-1/2 cups of low-fat milk, yogurt, or some combination, etc…
-Optional- Wisk an egg yolk into the milk.
-Optional- Add ¼ tsp salt.
-Optional- 2 TBS honey or Brown sugar. I use one 1 TBS of each.
Add some lemon or orange zest

Return to a boil for 10-15 minutes and then chill before eating. The oatmeal will congeal, resembling rice pudding.
Sprinkle more cinnamon/sugar on top
Add what you like: raisins, nuts, etc...

Use the cinnamon stick if you can, it really makes the difference. I’m constantly refining this recipe.

Once I decided to give up my (former) love affair with breakfast cereals, I was in a quandary about what to do for breakfast. I don't have much time in the morning to get creative and don't have the inclination at that time of the day to do so either.

I've settled on a routine of 2 hard-boiled (organic free-range) eggs (I boil them up a week in advance and leave them, shells-on, in the fridge), and a home-made protein-berry smoothie (frozen organic unsweetened berries, water-based).

This 8 am combo is easy, fast and tasty (I vary the berries and sometimes add natural flavour extracts for variety). It keeps my blood sugar flat and me full until my 1pm lunchtime. And I don't miss the cereals one bit!

I met an out-of-town friend for breakfast the other morning at a French-style bakery cafe. I ordered the goat cheese and herb omelet, but said I didn't want the potatoes or bread with it. They offered extra fruit or a salad instead. I chose the salad, with olive oil and vinegar. My friend wondered how I could eat a salad so early. Why not?

At home I usually eat 2 or 3 eggs over easy cooked in butter for breakfast most mornings and I am comfortably hungry for lunch about 3-4 hours later. But after my nicely filling cheese omelet and generous romaine salad (with a tiny bit of fruit - I ate the berries/melon and left the super-sweet pineapple), I wasn't hungry again until very late in the afternoon so had a small snack (cheese and half an apple) to hold me off and ate my next meal at dinner time. And it was a slow-developing comfortable hunger, not the powerful, "gotta eat something, anything" hunger that follows carb-heavy food.

Breakfast food, indeed!

You are absolutely right - breakfast is the most difficult meal to change. When I gave up wheat, I started using brown rice or potatoes mixed with anything interesting - nuts or meat or veges. I have now learned that these carbs make my blood glucose skyrocket. I have dropped the rice and potatoes and my BG has dropped nicely.

My favorite breakfast is sauteed veggies with some leftover meat or even an omelette. Soups are great in the AM. Nuts are for the days I am in a hurry.

Would be a little easier if I were not dairy intolerant.

Here in South India,it is 'Idli' - steam-cooked Lentil-rice (predominantly lentil) droppings, and 'Dosa' - lentil-rice pancakes. We have altered it a bit by increasing lentil ratio and dropping the rice to a minimum. Tastes good and fills you nice, for 4-5 hours.

I have two or three eggs, usually scrambled, but sunny-side-up and over-easy get thrown in for variety. I cook them using butter made from grass-fed cows. I also make my scrambled eggs using whipping cream instead of the more typical water or milk. I'll put a spoonful of fresh-made salsa over the top for some zing, some sliced cheese on the side and a cup of whole, organic milk to drink.

I'm completely sold on the "high-fat, moderate-protein, low-carb" diet and especially the admonition to start the day with a strong breakfast. My overall energy levels are fantastic, running performance is as good as high-school, and my belly hasn't looked this tight in decades.
