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.”

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.

Roger's near-miss CT angiogram experience

27. June 2009 William Davis (13)
Heart Scan Blog reader, Roger, described his near-miss experience with CT coronary angiograms.

Hoping to obtain just a simple CT heart scan, he was bullied to get a CT coronary angiogram instead. Roger held strong and just asked for the test that we all should be having, a CT heart scan.


I posted yesterday that I was about to have my first CT heart scan...well, it was an interesting experience for reasons I coudn't possibly have anticipated. Dr. Davis has commented in the past on the confusion in the media about the difference between a CT calcium score scan, and a CT angiography, the latter requiring a far higher dose of radiation. I assumed this was a source of confusion only among patients and lay folks, but, lo and behold, I discovered today that doctors--or at least their helpers--can be just as confused.

Here's my story:

After checking in, I asked the receptionist to see if she had any information on whether my medical insurance was covering the scan. She called someone, and I heard her say over the phone, "He's here for a CT angiogram." At that point my ears perked up. I explained I wasn't here for a CT angiogram, only a regular CT scan. "Well, do you want to call your doctor and talk about this?" she asked. No, I said, I would like to ask one of their folks to verify exactly what test my doctor had ordered. As luck would have it, the technician was walking by at that point. "Is this a CT angiogram?" the receptionist asked. "No, it's just a CT calcium score scan" was the reply. But apparently the technician had been unclear herself, and had called my doctor just to verify. In other words, the "default" procedure they were accustomed to doing at this august Houston vascular clinic was a CT angiogram.

In fact, my appointment was even listed on their calendar as a "CT angiogram." For all I know, my insurance will be billed for the same. Later, during the procedure, the technician acted surprised I wasn't doing the "full test." I explained I had minimal risk factors (actually only one, an HDL of 34 a couple of years ago, which has since been raised to 50 partly as a result of taking advice from this site), but that my doctor was progressive (he is an MD for the Houston Astros) and thought it was a good idea since there is heart disease in my immediate family. My doctor did indeed prescribe only a CT calcium score scan, but it seems to have been an order that this clinic, at least, wasn't all that used to seeing.

So, I guess the message is: we have a lot of educating to do. Had I not been a faithful reader of these pages, I certainly wouldn't have known what kind of test I was about to get, or what questions to ask!

As for the heart scan itself, a piece of cake. If you can hold your breath, you can take this test. Just be sure it is the right one!


Why the "push" towards CT coronary angiograms and not "just" a CT heart scan? Well, I know it's shocking but it's . . . money!

CT coronary angiograms yield around $1800-$4000 per test. CT heart scans yield somewhere around $200. Though the scan center support staff might not care too much about the money themselves, their administrators likely make the cost distinctions clear to them.

Another reason: Most scan center staff, ironically, don't understand what a heart scan means, nor do they understand how it might serve to launch a program of prevention. They do understand that severe blockage by CT angiogram "needs" to be stented or bypassed. So they push patients towards things they understand.

Nobody makes money from CT heart scans, just as nobody makes money from a mammogram. Heart scans also don't lead to heroic, "lifesaving" procedures. They just lead to this sleepy, unexciting, inexpensive thing called prevention.

The Myth of Prevention: Letter to the Wall Street Journal

25. June 2009 William Davis (20)




The June 20-21, 2009 Wall Street Journal Weekend Journal featured a provocative front page article written by physician, Dr. Abraham Verghese:

The Myth of Prevention

While eloquently written, I took issue with a few crucial points. Here is the letter I sent to the Editor at Wall Street Journal:


Dear Wall Street Journal Editor,

Re: Dr. Abraham Verghese’s article, The Myth of Prevention in the June 20-21, 2009 Weekend Journal.


I believe a more suitable title for Dr. Verghese’s article would be: “The Myth of What Passes as Prevention.”

As a practicing cardiologist, I, too, have witnessed firsthand the systemic “corruption” described by Dr. Verghese, the doing things “to” people rather than “for” them. Heart care, in particular, is rife with this form of profit-driven health delivery.

There is a fundamental flaw in Dr. Verghese’s otherwise admirable analysis: He assumes that what is called “prevention” in mainstream medicine is truly preventive.

Dr. Verghese makes issue of the apparent minor differences between preventing a condition and just allowing a condition to run its course. Prostate cancer screening is one example: Men subjected to repeated screenings have little length-of-life advantage over men who just allow their prostate to suffer the expected course of disease.

What if, instead, “prevention” as practiced today is nothing more than a solution that has been adopted in mainstream practice to suit yet another doing “to” strategy than doing “for”? In the prostate cancer example, PSA and prostate exam screenings often serve as little more than a means of harvesting procedures for the local urologist.

That’s not prevention. It is a prototypical example of “prevention” being subverted into the cause of revenue-generating procedures.

I submit that Dr. Verghese has fallen victim to the very same system he criticizes. His views have unwittingly been corrupted by the corrupt profit-driven system he describes.

What if, instead, prevention were just that: prevention or elimination of the condition. What if “prevention” of prostate cancer eliminated prostate cancer? What if heart disease “prevention” prevented all heart disease? What if this all proceeded without regard for profit or revenue-generating procedures, but just on results?

Dr. Verghese specifically targets heart scans or coronary calcium scoring, a test he likens to “miracle glow-in-the-dark minnow lures,” calling them “moneymakers.” Yes, when subverted into a corrupt algorithm of stress test, heart catheterization, stent, or bypass, heart scans are indeed a test used wrongly to “prevent” heart disease.

But what if the risk insights provided by heart scans prompt the start of a benign yet effective “prevention” program that inexpensively, safely, and assuredly prevents--in the true sense of the word--or eliminates heart disease? Then I believe the differences in mortality, quality of life, and costs would be substantial. Such strategies exist, yet do not necessarily include prescription drugs and certainly do not include the aftermath of heart catheterization and bypass surgery. Yet such programs fail to seize the limelight of media attention with no new high-tech lifesaving headline nor a big marketing budget to broadcast its message.

The problem in medicine is not prevention and its failure to yield cost- and life-saving results. It is the pervasively profit-driven mindset that keeps true preventive strategies from entering mainstream conversation. It is a repeat of Dr. Ignaz Semmelweis’ late 19th-century pleads for physicians to wash their hands before delivering babies to reduce puerperal sepsis, ignominious advice that earned him life and death in an asylum. We are essentially continuing to deliver children with unwashed hands because there is no revenue-generating procedure to clean them.

No, Dr. Verghese, the economic and medical failings of preventive strategies are not at fault. The failure of the medical system, in which everyone is bent on seizing a piece of the financial action for himself, has resulted in the failure to support the propagation of true preventive strategies that could genuinely save money and lives.

President Obama’s goal of cultivating preventive practices in medicine can work, but only if the profit-motive for “prevention” does not serve as the primary determinant of practice. Results-driven practices that are applied without regard to profit have the potential to yield the sorts of cost-saving and life-saving results that can reduce healthcare costs.

A victory for SHAPE, CT heart scans, and doing what is RIGHT

24. June 2009 William Davis (7)
The efforts of Texas House of Representatives Rep. Rene Oliveira and the SHAPE Guidelines committee have paid off: The Texas legislature passed a bill that requires health insurers to cover CT heart scans.

(NOTE: Don't make the same mistake that the media often makes and confuse CT heart scans with CT coronary angiography: two different tests, two different results, two different levels of radiation exposure. The difference is discussed here.)

Track Your Plaque previously reported the release of the SHAPE Guidelines, an ambitious effort to open CT heart scanning to people who would benefit from a simple screening test for coronary disease. Rep. Rene Oliveira initially introduced the bill in 2006, after having a heart scan uncovered extensive coronary plaque that resulted in coronary bypass surgery.

The bill requires that health-benefit providers cover the cost of CT heart scans (and carotid ultrasound) in men between the ages of 45-76, women 55-76, as well as anyone with diabetes or at "intermediate-risk" or higher for coronary disease by Framingham risk score.

The usual panel of cardiology knuckleheads stepped to the media podium, expressing their incredulity that something as "unvalidated" as heart scans could gain the backing of legislative mandate. Heartwire carried this comment:

"Contacted by heartwire, Dr Amit Khera (University of Texas Southwestern Medical Center, Dallas) confirmed there are still no comprehensive, adequately powered studies showing that these screening tests lead to better outcomes. In a phone interview, Khera said he has major concerns about how physicians will use these tests, particularly primary-care physicians. "I gave a talk last week to primary-care doctors, and there were probably 250 people in the room, and when I asked how many people had ordered a calcium scan, just one person raised a hand. . . . Most people don't even know what to do with the Framingham risk score, so they're going to follow an algorithm that they don't know how to follow to order a test result that they don't know what to do with."

It's the same criticisms hurled at heart scans over the years despite literally thousands of studies validating their application.

Studies have conclusively shown that:

--Coronary calcium scores generated by a CT heart scan outperform any other risk measure for coronary disease, including LDL cholesterol, c-reactive protein, total cholesterol, HDL cholesterol, blood pressure.
--Coronary calcium scores yield a graded, trackable index of coronary risk. Scores that increase correlate with increased risk of cardiovascular events; scores that remain unchanged correlate with much reduced risk.
--A coronary calcium score of zero--no detectable calcium--correlates with extremely low 5-year risk for cardiovascular events.
--Coronary calcium scores correlate with other measures of coronary disease. Heart scans correlate with coronary angiography, quantitative coronary angiography, carotid ultrasound (intimal-medial thickness and plaque severity), ankle-brachial index, and stress tests, including radionuclide (nuclear) perfusion imaging.

The reluctance of my colleagues to embrace heart scans stems from two issues, for the most part:

1) No study has yet been performed showing that knowing what the score is vs. not knowing what the score is changes prognosis. That's true. But it is also true of the great majority of practices in medicine. While many wrongs don't make a right, the miserable and widespread failure of other coronary risk measures, like LDL cholesterol or c-reactive protein, to readily and reliably detect hidden coronary disease creates a gaping void for improved efforts at early detection. If your LDL cholesterol is 140 mg/dl, do you or don't you have coronary disease? If your doctor's response is "Just take a statin drug anyway" you've been done a great disservice. (If and when this sort of study gets done, its huge cost--outcome studies have to be large and last many years--it will likely be a statin study. It is unlikely it will include such Track Your Plaque strategies that help reduce heart scan scores, like vitamin D and correction of small LDL particles.)

2) Fears over overuse of hospital procedures triggered by heart scans. This is a legitimate concern--if the information provided by a heart scan is misused. Heart scans should never--NEVER--lead directly to heart catheterization, stents, bypass surgery. Heart scans do not change the indications for performing revascularization (angioplasty, stents, bypass). Just because 20% of my cardiology colleagues are more concerned with profit rather than patient welfare does not invalidate the value of the test. Just because the mechanic at the local garage gouged you by replacing a carburetor for $800 when all you need was a new spark plug does not mean that we should outlaw all auto mechanics. Abuse is the fault of the abuser, not of the tool used to exercise the abuse.


All in all, while I am not a fan of legislating behavior in healthcare, the blatant and extreme ignorance of this simple tool for uncovering hidden heart disease makes the Texas action a huge success for heart disease prevention. I hope that this success will raise awareness, not just in Texas, but in other states and cities in which similar systemic neglect is the rule.

Remember: CT heart scans are tools for prevention, not to uncover "need" for procedures. They serve as a starting point to decide whether or not an intensive program of prevention is in order, and I don't mean statin vs. no statin.

Though not a multi-million dollar statin drug study, I have NEVER seen a heart attack or "need" for procedure in any person who has stopped progression or reduced their heart scan score. A small cohort from my practice was reported:

Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.

Davis W, Rockway S, Kwasny M.

The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides /=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.

Sleep: A to Zzzzzzzzzz

23. June 2009 William Davis (5)
Take a look at the results from the Heart Scan Blog's most recent reader poll (399 respondents):

How many hours do you sleep per night (on average)?


9 or more hours per night
15 (3.7%)

8-9 hours per night
72 (18%)

7-8 hours per night
152 (38.1%)

6-7 hours per night
111 (27.8%)

5-6 hours per night
38 (9.5%)

Less than 5 hours per night
11 (2.8%)


Like many issues in health, too much or too little of a good thing can present undesirable consequences.

Too much sleep: While psychologists and sleep researchers advise us that at least 9 hours are required to fully eliminate sleep "debt" and achieve optimal vigilance and mental performance, epidemiologic studies have shown increased mortality with this quantity of sleep.

Too little sleep: Getting less than 7 hours habituallly increases blood sugar, appetite, inflammatory measures, and encourages weight gain. Mortality is also increased, just as with sleeping too much. It is also associated with increased likelihood of a positive heart scan score.

7-8 hours per night from a health viewpoint is that Goldlilocks "just right" value: just enough to not erode mental performance substantially, but not so little that inflammatory, insulin-disrupting, and appetite-increasing effects develop.

Of our 399 respondents in the poll, 56.1% (38% + 18%) slept what appears to be an optimal amount for health. While only 3.7% slept too much (9 hours or more), the remaining 40.1% slept too little.

Our informal poll confirms what most of us observe in everyday life: The majority of people shortchange sleep in order to meet the demands of their high-pressure, squeeze-as-much-as-possible-into-every-day lives. But not paying off your sleep "debt" is like not paying the mortgage for a couple of months. You wouldn't expect your friendly neighborhood bank to say, "Oh, you forgot to pay your mortgage? Forget about it. Just pay next month's." Sure, fat chance. But if you don't pay off your sleep "debt," you will pay it back with health.

Near-fatal brush with nattokinase

14. April 2010 William Davis (0)
Here is precisely why I have spoken out against nattokinase: People may put faith in this "supplement" when there are virtually no data to support its use in such dangerous conditions as pulmonary embolism.

Pulmonary embolism occurs when a large volume of blood clots in the veins of the pelvis, abdomen, and into the legs. A clot breaks off and lodges in the pulmonary arteries of the lungs. This can be fatal within minutes to hours, the victim struggling to breathe, since oxygen is not transferred to the blood and it causes terrible pain in the chest.

The treatments are fairly obnoxious: intravenous anticoagulants (blood thinners), followed by oral blood thinners like warfarin. While they carry risk of bleeding and other long-term risks, it's better than dying.

Would you bet that a "nutritional supplement" manufacturer's vague claims and lack of data are sufficient proof to treat a life-threatening condition? You're a fool if you are.

Anyone reading these pages knows that I am a vigorous supporter of nutritional supplements. I even consult for the nutritonal supplement industry. But I am also an advocate of TRUTH, not BS.

Here is a woman from England who inquired whether she should stop her husband's warfarin in favor of nattokinase. This is precisely the sort of thing that can happen because of the campaign of misinformation behind nattokinase.


Dr. Davis,

Thank you for your very interesting blogs, which I came across searching for natural alternative treatments to warfarin.

My husband has been following the low carb, high fat, real food regime over the past few years. He got off all the blood pressure and cholesterol drugs and never felt better. He even got his blood sugar down from a recorded high that we are aware of 13 nmol/L (234 mg/dol) to 6.1 nmol/L 109.8 mg/dl).

We were on holiday in the Caribbean. Just before our return home, we did a trip to a neighbouring island that included non-alcoholic fruit punches. They tasted great, but were very sweet. I broke my normal refusal to drink these things, but only had a couple of glasses. (After all, we were on holiday!) My husband believes he consumed around 1.5 litres of the stuff and now realises he was feeding his body a very toxic product – fructose. That night, he had an incredible toxic response and we only got him onto the plane with a visit to the hospital and a pain killer injection.

The symptoms of pulmonary embolism only showed 2 weeks later . . . and warfarin treatment was started. We would both like to use an alternative therapy if we can find someone with experience to provide the support.Do you know of any studies that support alternative options?

Do you know of any practitioners in the England who support a non-drug approach with an understanding of nutrition who we may be able to receive advice and support?

Glucophobia: The Novel

13. April 2010 William Davis (25)
Just kidding: No novel here. However, there is indeed a story to tell that should scare the pants off you.

If you haven't yet gathered that carbohydrates are a macronutrient nightmare, let me recount the list:


Carbohydrates increase small LDL particles
Or, in the cholesterol-speak most people understand, "carbohydrates increase cholesterol." It's counterintuitive, but carbohydrates increase LDL substantially, far more than any fat.


Carbohydrates increase blood sugar
Eggs don't increase blood sugar, nor do chicken, raw almonds, onions or green peppers. But a bowl of oatmeal will send your blood sugar skywards.


Carbohydrates make you fat
Carbohydrates, whether in the form of wheat flour in your whole wheat bread, sucrose in your ice cream, fructose in your "organic Agave nectar," or high-fructose corn syrup in your dill pickles. They all provoke de novo lipogenesis, or fat formation. They also stimulate insulin, the hormone of fat storage.


Carbohydrates cause glycation
High blood sugar, like the kind that develops after a bowl of oatmeal, triggers glycation, or modification of proteins by glucose (blood sugar). This is how cataracts, kidney disease, and atherosclerotic plaque develop. Small LDL is 8-fold more glycation prone than large LDL, providing a carbohydrate double-whammy.


Your glucose meter remains the single best tool to gauge the quality of your diet. Many people have horror stories of the shocking experiences they've had when they finally get around to checking their postprandial glucose.

Drama with the Dr. Oz Show

11. April 2010 William Davis (27)
A producer from the Dr. Oz show recently contacted my office. They asked whether we could supply them with a volunteer patient from either my practice or the Track Your Plaque program who would be willing to appear on the show and discuss heart disease prevention. They needed someone to commit within 24 hours.

Despite the short notice, we identified a volunteer. He flew to New York the following week where he was interviewed along with several other men and women, all of whom had heart disease (heart attacks, stents, etc.). However, as this young man is very slender and follows most of the Track Your Plaque principles (e.g., vitamin D and omega-3 fatty acid supplementation; no wheat, cornstarch, or sugars, no restriction of fat, etc.), he apparently received less attention than the overweight, I-know-nothing-about-diet interviewees.

Then there was an odd turn of events: Dr. Dean Ornish, apparently a friend of Dr. Oz, will be providing the dietary counseling. The producer had made no mention of Dr. Ornish.

Now that's an odd collision of philosophies: Our Track Your Plaque version of low-carb with the guru of low-fat, Dr. Ornish.

The following week, Dr. Ornish called me and graciously asked whether I was okay with this. I'm not sure just how much he knew about the philosophy I advocate, nor how much I have bashed his program as a destructive approach to diet, nor whether he knew that I gained 30 lbs on the Ornish diet, along with a drop in HDL to 27 mg/dl, increased triglycerides to 350 mg/dl, and type II diabetes that I've talked about on this blog and the Track Your Plaque book and website. I suspect he knew little to none of this.

Anyway, I tried to diplomatically explain that my patient's cause for coronary plaque was small LDL particles that he expressed despite his very slender build, likely from excessive carbohydrates, controlled with carbohydrate restriction. Dr. Ornish maintained his usual arguments: Grains are good, provided they are whole grains, heart disease is "reversed" with his diet program, etc. (I didn't want to challenge him in a phone call and tell him that he never actually reversed coronary plaque, but just reversed endothelial dysfunction. But, as Dr. Ornish is not a cardiologist, I wasn't sure how far his understanding of these issues went.)

We agreed to disagree. This leaves my poor patient in an odd position: Being asked by Dr. Ornish and the Dr. Oz show to follow a low-fat program for the sake of entertainment, or adhering to the advice we follow that has so far served him well, given his small LDL particle size tendencies.

We'll see where this little drama leads.

Response from Nature Made

10. April 2010 William Davis (31)
Here's the response from Nature Made when I emailed them about my concern that there appears to be no vitamin D in their vitamin D gelcaps.

It is the usually CYA corporate-speak that says nothing. The grammatical errors make it clear that this was a "canned" response.



Date: April 9, 2010
From: Marissa Reyes, Consumer Affairs Department
Subject: Reference #346236

Dear William Davis, MD:

We recently received your e-mail regarding Nature Made products. We regret to
hear that the quality standards of our company. [?]

Our company is called Pharmavite, and we manufacture Nature Made nutritional
supplements. We have been in business since 1971. We are committed to quality
control, and have very high quality standards. Our Quality Control personnel
sample and test all raw materials as they enter our plant, and again assay the
finished product, before final packaging.

Dietary Supplements are regulated under the FDA through DSHEA (Dietary
Supplement Health & Education Act of 1994). The United States Pharmacopoeia
(USP) establishes standards for the composition of drugs and nutritional
supplements. This voluntary non governmental organization was set up in 1820
and has officially been recognized by federal law since 1906. Standards
established by USP for products are legally enforceable by the FDA. At
Pharmavite we participate in the USP Dietary Supplement Verification Program
(DSVP). Many of our products have earned the DSVP seal and additional products
are currently being evaluated. Our DSVP certified products will have the DSVP
seal on the product label.

Our Nature Made Vitamin D 400 IU tablets have been reviewed by the USP and bears
the DSVP symbol on the label. Although the USP has not reviewed all of the
Nature Made Vitamin D supplements, all of our products go through the same
rigorous quality testing at Pharmavite. The products which have earned the seal
help us to demonstrate the high quality of our products.

We would like to look into the product(s) your patients have been using. If you
could provide the UPC and lot numbers of the product(s), we will be happy to

postage mailer.

We thank you for contacting us and hope that you will continue to use and enjoy
Nature Made products with complete confidence.

Sincerely,
Marissa Reyes
Consumer Affairs Coordinator
Pharmavite, LLC
MR:346236-10


Patients who come to the office do not provide me with the bottles nor lot numbers. In past, when I've gone to the trouble of doing this (with other companies, not Nature Made), it has come to nothing helpful. The information gets passed on to the company and we hear nothing and never learn if there was a problem, or receive some more corporate-speak letter saying everything was fine. This is obviously a liability-avoidance tactic: Admitting that something was wrong would open them up to legal risk. So, frankly, I can't be bothered.

So we are left with the unsatisfying experience of relying on street-level experiences.

For now, my advice: Avoid Nature Made vitamin D. Too many people have had blood tests demonstrating that they are not obtaining any vitamin D.

By the way, the Nature Made brand of fish oil is among the very few problem brands of fish oil we've encountered. Fish oil should be only mildly fish in smell and generally should not cause stomach upset and excessive belching if properly purified. Nature Made is excessively fishy when you smell it, suggesting oxidation. We've had repeated (dozens) of patients who have experienced difficulties with this brand. Rather than dealing with the frustrating gobbledy-gook of this company, just avoid their products.

What to Eat: The diet is defined by small LDL

9. April 2010 William Davis (15)
I approach diet from the perspective of small LDL particles.

Small LDL particles have exploded in frequency and severity in Americans. It is not at all uncommon to see 70% or more small LDL particles (i.e., 70% of total LDL particle number or Apo B) on lipoprotein testing. (I saw two people today who began with over 95% small LDL.)

Small LDL particles are:
--More likely to persist in the bloodstream longer than large LDL particles.
--More likely to adhere to components of atherosclerotic plaque.
--More likely to gain entry to plaque.
--More likely to be taken up by inflammatory white blood cells which, in turn, become the mast cells that fill coronary plaque.
--More likely to be oxidized.
--More likely to be glycated (8-fold more likely than large)

To add insult to injury, foods that trigger small LDL formation--i.e., carbohydrates--also cause high postprandial blood sugars. High postprandial blood sugars, in turn, glycate small LDL. That combination of events accelerates 1) plaque growth, 2) plaque instability, and 3) aging.

So carbohydrates trigger this sequence, carbohydrates of all stripes and colors. Not just "white" carbohydrates, but ALL carbohydrates. It's all a matter of degree and quantity. So, yes, even quinoa, bulghur, and sorghum trigger this process. I've only recently appreciated just how bad oats and oatmeal are in this regard--really bad.

Foods that trigger small LDL also trigger higher blood sugars; foods that trigger higher blood sugars also trigger small LDL. Small LDL and blood sugar are two different things, but they track each other very closely.

So, in the Track Your Plaque approach to diet, we craft diet based on these simple principles:

1) Eliminate wheat, cornstarch, and sugars--These are the most flagrant triggers of small LDL, blood sugar, and, therefore, LDL glycation.
2) The inclusion of other carbohydrates, such as oatmeal, quinoa, rye, etc. depends on individual sensitivity. Individual sensitivity is best gauged by assessing one-hour postprandial glucose.

Stay tuned for more in this series. Also, Track Your Plaque Members: We will be having an in-depth webinar detailing more on thees principles in the next couple of weeks.

Is it or isn't it vitamin D?

7. April 2010 William Davis (63)
Jackie takes 10,000 units of vitamin D(3) per day as a gelcap.

Her starting 25-hydroxy vitamin D blood level was 18.1 ng/ml. Severe deficiency, no surprise.

On her 10,000 units per day, Vitamin Shoppe brand, her 25-hydroxy vitamin D level was 76.2 ng/ml--perfect. It stayed in this range for about two years.

She then changed to the Nature Made brand gelcaps she picked up at Walgreen's. Repeat 25-hydroxy vitamin D level: 23 ng/ml.

This has now happened with five different people, all taking the Nature Made brand.

If you are taking this brand of vitamin D, please be on the alert. You might consider a 25-hydroxy vitamin D blood level to be sure it actually has the vitamin D it's supposed to have.

Or, change brands.

What to eat: Part I

6. April 2010 William Davis (0)
I've spent a good number of Heart Scan Blog posts detailing what foods to limit or avoid.

The list of unquestionably bad foods to avoid include foods made of wheat, cornstarch, and sugars. Fructose is proving to be an exceptionally bad form of sugar, worse than any other. I've issued warnings about levels of carbohydrates that can be determined by postprandial testing.

In response to several requests to clarify what foods to eat, this post begins a series discussing what foods are good to eat.

I believe that a strong case can be made for eating vegetables in nearly all its varied forms, from cucumbers to peppers to leafy vegetables to eggplant to alliums like onions. The only form we avoid are red and white potatoes due to the blood sugar-increasing effects.

While this seems obvious, I am impressed how many people who follow low-carb diets find themselves following a high-animal product diet with vegetables as the sideline. It should be the other way around: A high vegetable diet with animal products as the sideline.

Vegetables are your principal source of:

1) Flavonoids and polyphenols--e.g., anthocyanins and catechins. All the recently appreciated effects of flavonoids and polyphenols highlight the wonderful effects of compounds originating in plant foods. This includes the anthocyanins and resveratrol in red wine; the catechins and epicatechins cocoa and green tea; the hydroxytyrosol, phenolic acid, and flavonoids of olive oil.

2) Fiber--Fiber is essentially a plant phenomenon, since there is virtually none in chicken, fish, and beef. The benefits of fiber are, I believe, undisputed. Neglecting fiber can, at the very least, lead to a nasty case of hemorrhoids. At the worst, it is related to various cancers, especially colon cancer.

3) Vitamin C--While vitamin C may be old and boring in light of new, exciting discoveries like flavonoids, neglect leads to bad things.

Vegetables are generally classified as carbohydrate foods, since they are low in protein and fat. But this is the source of carbohydrates you do not want to sacrifice in a low-carbohydrate diet. There's just too much good from vegetables.

Notice that I didn't say "fruits and vegetables." This is a fundamental mistake made by many: Oveconsumption of fruits. I've even seen people who follow an otherwise good diet develop diabetes--just from too much fruit.

Vegetables should be the cornerstone of the human diet. But I'll bet you knew that already.

Carbohydrates and LDL

4. April 2010 William Davis (16)
There's a curious and powerful relationship between carbohydrates and LDL particles. Understanding this relationship is crucial to gaining control over heart disease risk.

(Note that I did not say "LDL cholesterol"--This is what confuses people, the notion that cholesterol is used as a surrogate marker to quantify various lipoproteins, including low-density lipoproteins, LDL. I'm NOT interested in the cholesterol; I'm interested in the behavior of the low-density lipoprotein particle. There's a difference.)

Carbohydrates:

1) Increase triglycerides and very low-density lipoprotein particles (VLDL)
2) Triglyceride-rich VLDL interact with LDL particles, making them smaller. (A process mediated by several enzymes, such as cholesteryl-ester transfer protein.)
3) Smaller LDL particles are more oxidizable--Oxidized LDL particles are the sort that are taken up by inflammatory white blood cells residing in the artery wall and atherosclerotic plaque.
4) Smaller LDL particles are more glycatable--Glycation of LDL is an important phenomenon that makes the LDL particle more atherogenic (plaque-causing). Glycated LDLs are not recognized by the LDL receptor, causing them to persist in the bloodstream longer than non-glcyated LDL. Glycated LDL is therefore taken up by inflammatory white blood cells in plaque.

Of course, carbohydrates also make you fat, further fueling the fire of this sequence.

The key is to break this chain: Cut out the carbohydrates. Cut carbohydrates and VLDL and triglycerides drop (dramatically), VLDL are unavailable to transform large LDL into small LDL, small LDL is no longer available to become oxidized and glycated, blood sugar is reduced to allow less glycation. Voila: Less atherosclerotic plaque growth.

Yet the USDA, American Heart Association, and the Surgeon General's office all advise you to eat more carbohydrates. The American Diabetes Association tells you to eat 70 grams or so carbohydrates per meal. (Yes: Diabetes, the condition that is MOST susceptible to these carbohydrate effects.) Follow their advice and you gain weight; triglycerides and VLDL go up; calculated (Friedewald) LDL may or may not go up, but true measured LDL (NMR LDL particle number or apoprotein B) goes way up; small LDL is triggered . . . You know the rest.

The dance between carbohydrates and LDL particles requires the participation of both. Allow one partner to drop out of the dance and LDL particles will sit this dance out.

Strange but true: Part II

4. April 2010 William Davis (0)
Here's the second part of the Heart Scan Blog post I wrote a couple of years back describing the wacky origins of this thing that has so changed the face of heart care in the U.S., the cardiac catheterization.

Heart catheterization: Strange, but true

3. April 2010 William Davis (1)
It's a couple of years old, but this post from March, 2008, remains relevant.

It details the curious origins of heart catheterization, the procedure that has saved some lives, but also been responsible for the proliferation of unnecessary heart procedures.



The modern era of heart disease care was born from an accident, quirky personalities, and even a little daring.

The notion of heart catheterization to visualize the human heart began rather ignominiously in 1929 at the Auguste-Viktoria Hospital in Eberswalde, Germany, a technological backwater of the day. Inspired by descriptions of a French physician who inserted a tube into the jugular vein of a horse and felt transmitted heart impulses outside the body, Dr. Werner Forssmann, an eager 25-year old physician-in-training, was intent on proving that access to the human heart could be safely gained through a surface blood vessel. No one knew if passing a catheter into the human heart would be safe, or whether it would become tangled in the heart’s chambers and cause it to stop beating. On voicing his intentions, Forssmann was ordered by superiors not to proceed. But he was determined to settle the question, especially since his ambitions captured the interest of nurse Gerda Ditzen, who willingly even offered to become the first human subject of his little experiment.

Secretly gathering the necessary supplies, he made his first attempt in private. After applying a local anesthetic, he used a scalpel to make an incision in his left elbow. He then inserted a hollow tube, a catheter intended for the bladder, into the vein exposed under the skin. After passing the catheter 14 inches into his arm, however, he experienced cold feet and pulled it out.



One week later, Forssman regained his resolve and repeated the process. Nurse Ditzen begged to be the subject, but Forssmann, in order to allow himself to be the first subject, tricked her into being strapped down and proceeded to work on himself while she helplessly watched. After stanching the oozing blood from the wound, he threaded the catheter slowly and painfully into the cephalic vein, up through the bicep, past the shoulder and subclavian vein, then down towards the heart. He knew that simply nudging the rubber catheter forward would be sufficient to direct it to the heart, since all veins of the body lead there. With the catheter buried 25 inches into his body, Forssmann untied the fuming Ditzen. Both then ran to the hospital’s basement x-ray department and injected x-ray dye into the catheter, yielding an image of the right side of his heart, the first made in a living human.

Thus, the very first catheterization of the heart was performed.

An x-ray image was made to document the accomplishment. Upon hearing of the experiment, Forssmann was promptly fired by superiors for his brazen act of self-experimentation. Deflated, Forssmann abandoned his experimentation and went on to practice urology. He became a member of the Nazi party in World War II Germany and served in the German army. Though condemned as crazy by some, physicians in Europe and the U.S., after hearing of his experience, furthered the effort and continued to explore the potential of the technique. Forssmann himself was never invited to speak of his experiences outside of Germany, as he had been labeled a Nazi.

Many years after his furtive experiments, the once intrepid Dr. Forssmann was living a quiet life practicing small town medicine. He received an unexpected phone call informing him that he was one of three physicians chosen to receive the 1956 Nobel Prize for Medicine for his pioneering work performing the world’s first heart catheterization, along with Drs. André Cournand and Dickinson W. Richards, both of whom had furthered Forssmann’s early work. Forssmann remarked to a reporter that he felt like a village pastor who was made a cardinal.

Strange, but true.

For the sake of convenience: Commercial sources of prebiotic fibers

3. May 2015 William Davis (0)
Our efforts to obtain prebiotic fibers/resistant starches, as discussed in the Cureality Digestive Health Track, to cultivate healthy bowel flora means recreating the eating behavior of primitive humans who dug in the dirt with sticks and bone fragments for underground roots and tubers, behaviors you can still observe in extant hunter-gatherer groups, such as the Hadza and Yanomamo. But, because this practice is inconvenient for us modern folk accustomed to sleek grocery stores, because many of us live in climates where the ground is frozen much of the year, and because we lack the wisdom passed from generation to generation that helps identify which roots and tubers are safe to eat and which are not, we rely on modern equivalents of primitive sources. Thus, green, unripe bananas, raw potatoes and other such fiber sources in the Cureality lifestyle.

There is therefore no need to purchase prebiotic fibers outside of your daily effort at including an unripe green banana, say, or inulin and fructooligosaccharides (FOS), or small servings of legumes as a means of cultivating healthy bowel flora. These are powerful strategies that change the number and species of bowel flora over time, thereby leading to beneficial health effects that include reduced blood sugar and blood pressure, reduction in triglycerides, reduced anxiety and improved sleep, and reduced colon cancer risk.

HOWEVER, convenience can be a struggle. Traveling by plane, for example, makes lugging around green bananas or raw potatoes inconvenient. Inulin and FOS already come as powders or capsules and they are among the options for a convenient, portable prebiotic fiber strategy. But there are others that can be purchased. This is a more costly way to get your prebiotic fibers and you do not need to purchase these products in order to succeed in your bowel flora management program. These products are therefore listed strictly as a strategy for convenience.

Most perspectives on the quality of human bowel flora composition suggest that diversity is an important feature, i.e., the greater the number of species, the better the health of the host. There may therefore be advantage in varying your prebiotic routine, e.g., green banana on Monday, inulin on Tuesday, PGX (below) on Wednesday, etc. Beyond providing convenience, these products may introduce an added level of diversity, as well.

Among the preparations available to us that can be used as prebiotic fibers:

PGX

While it is billed as a weight management and blood sugar-reducing product, the naturally occurring fiber--α-D-glucurono-α-D-manno-β-D-manno- β-D-gluco, α-L-gulurono-β-D mannurono, β-D-gluco-β- D-mannan--in PGX also exerts prebiotic effects (evidenced by increased fecal butyrate, the beneficial end-product of bacterial metabolism). PGX is available as capsules or granules. It also seems to exert prebiotic effects at lower doses than other prebiotic fibers. While I usually advise reaching 20 grams per day of fiber, PGX appears to exert substantial effects at a daily dose of half that quantity. As with all prebiotic fibers, it is best to build up slowly over weeks, e.g., start at 1.5 grams twice per day. It is also best taken in two or three divided doses. (Avoid the PGX bars, as they are too carb-rich for those of us trying to achieve ideal metaobolic health.)

Prebiotin

A combination of inulin and FOS available as powders and in portable Stick Pacs (2 gram and 4 gram packs). This preparation is quite costly, however, given the generally low cost of purchasing chicory inulin and FOS separately.

Acacia

Acacia fiber is another form of prebiotic fiber.  RenewLife and NOW are two reputable brands.

Isomalto-oligosaccharides

This fiber is used in Quest bars and in Paleo Protein Bars. With Quest bars, choose the flavors without sucralose, since it has been associated with undesirable changes in bowel flora.

There you go. It means that there are fewer and fewer reasons to not purposefully cultivate healthy bowel flora and obtain all the wonderful health benefits of doing so, from reduced blood pressure, to reduced triglycerides, to deeper sleep.

Disclaimer: I am not compensated in any way by discussing these products.

How Not To Have An Autoimmune Condition

20. April 2015 William Davis (0)

Autoimmune conditions are becoming increasingly common. Estimates vary, but it appears that at least 8-9% of the population in North America and Western Europe have one of these conditions, with The American Autoimmune Related Diseases Association estimating that it’s even higher at 14% of the population.

The 200 or so autoimmune diseases that afflict modern people are conditions that involve an abnormal immune response directed against one or more organs of the body. If the misguided attack is against the thyroid gland, it can result in Hashimoto’s thyroiditis. If it is directed against pancreatic beta cells that produce insulin, it can result in type 1 diabetes or latent autoimmune diabetes of adults (LADA). If it involves tissue encasing joints (synovium) like the fingers or wrists, it can result in rheumatoid arthritis. It if involves the liver, it can result in autoimmune hepatitis, and so on. Nearly every organ of the body can be the target of such a misguided immune response.

While it requires a genetic predisposition towards autoimmunity that we have no control over (e.g., the HLA-B27 gene for ankylosing spondylitis), there are numerous environmental triggers of these diseases that we can do something about. Identifying and correcting these factors stacks the odds in your favor of reducing autoimmune inflammation, swelling, pain, organ dysfunction, and can even reverse an autoimmune condition altogether.

Among the most important factors to correct in order to minimize or reverse autoimmunity are:

Wheat and grain elimination

If you are reading this, you likely already know that the gliadin protein of wheat and related proteins in other grains (especially the secalin of rye, the hordein of barley, zein of corn, perhaps the avenin of oats) initiate the intestinal “leakiness” that begins the autoimmune process, an effect that occurs in over 90% of people who consume wheat and grains. The flood of foreign peptides/proteins, bacterial lipopolysaccharide, and grain proteins themselves cause immune responses to be launched against these foreign factors. If, for instance, an autoimmune response is triggered against wheat gliadin, the same antibodies can be aimed at the synapsin protein of the central nervous system/brain, resulting in dementia or cerebellar ataxia (destruction of the cerebellum resulting in incoordination and loss of bladder and bowel control). Wheat and grain elimination is by far the most important item on this list to reverse autoimmunity.

Correct vitamin D deficiency

It is clear that, across a spectrum of autoimmune diseases, vitamin D deficiency serves a permissive, not necessarily causative, role in allowing an autoimmune process to proceed. It is clear, for instance, that autoimmune conditions such as type 1 diabetes in children, rheumatoid arthritis, and Hashimoto’s thyroiditis are more common in those with low vitamin D status, much less common in those with higher vitamin D levels. For this and other reasons, I aim to achieve a blood level of 25-hydroxy vitamin D level of 60-70 ng/ml, a level that usually requires around 4000-8000 units per day of D3 (cholecalciferol) in gelcap or liquid form (never tablet due to poor or erratic absorption). In view of the serious nature of autoimmune diseases, it is well worth tracking occasional blood levels.

Supplement omega-3 fatty acids

While omega-3 fatty acids, EPA and DHA, from fish oil have proven only modestly helpful by themselves, when cast onto the background of wheat/grain elimination and vitamin D, omega-3 fatty acids compound anti-inflammatory benefits, such as those exerted via cyclooxygenase-2. This requires a daily EPA + DHA dose of around 3600 mg per day, divided in two. Don’t confuse EPA and DHA omega-3s with linolenic acid, another form of omega-3 obtained from meats, flaxseed, chia, and walnuts that does not not yield the same benefits. Nor can you use krill oil with its relatively trivial content of omega-3s.

Eliminate dairy

This is true in North America and most of Western Europe, less true in New Zealand and Australia. Autoimmunity can be triggered by the casein beta A1 form of casein widely expressed in dairy products, but not by casein beta A2 and other forms. Because it is so prevalent in North America and Western Europe, the most confident way to avoid this immunogenic form of casein is to avoid dairy altogether. You might be able to consume cheese, given the fermentation process that alters proteins and sugar, but that has not been fully explored.

Cultivate healthy bowel flora

People with autoimmune conditions have massively screwed up bowel flora with reduced species diversity and dominance of unhealthy species. We restore a healthier anti-inflammatory panel of bacterial species by “seeding” the colon with high-potency probiotics, then nourishing them with prebiotic fibers/resistant starches, a collection of strategies summarized in the Cureality Digestive Health discussions. People sometimes view bowel flora management as optional, just “fluff”–it is anything but. Properly managing bowel flora can be a make-it-or-break-it advantage; don’t neglect it.

There you go: a basic list to get started on if your interest is to begin a process of unraveling the processes of autoimmunity. In some conditions, such as rheumatoid arthritis and polymyalgia rheumatica, full recovery is possible. In other conditions, such as Hashimoto’s thyroiditis and the pancreatic beta cell destruction leading to type 1 diabetes, reversing the autoimmune inflammation does not restore organ function: hypothyroidism results after thyroiditis quiets down and type 1 diabetes and need for insulin persists after pancreatic beta cell damage. But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery

Five Powerful Ways to Reduce Blood Sugar

4. April 2015 William Davis (0)
Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess.

If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics.

Among the most powerful and effective strategies to reduce blood sugar:

1) Eat no wheat nor grains

Recall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.

2) Add no sugars, avoid high-fructose corn syrup

This should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.

3) Vitamin D

Because vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.

4) Restore bowel flora

As cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)

5) Exercise

Blood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.

Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health. This is our core mission in Cureality. A nice side benefit: information from Cureality is not accompanied by advertisements from Merck, Pfizer, Kelloggs, Kraft, or Cadbury Schweppes.

Cureality App Review: Breathe Sync

7. March 2015 William Davis (0)


Biofeedback is a wonderful, natural way to gain control over multiple physiological phenomena, a means of tapping into your body’s internal resources. You can, for instance, use biofeedback to reduce anxiety, heart rate, and blood pressure, and achieve a sense of well-being that does not involve drugs, side-effects, or even much cost.

Biofeedback simply means that you are tracking some observable physiologic phenomenon—heart rate, skin temperature, blood pressure—and trying to consciously access control over it. One very successful method is that of bringing the beat-to-beat variation in heart rate into synchrony with the respiratory cycle. In day-to-day life, the heart beat is usually completely out of sync with respiration. Bring it into synchrony and interesting things happen: you experience a feeling of peace and calm, while many healthy phenomena develop.

A company called HeartMath has applied this principle through their personal computer-driven device that plugs into the USB port of your computer and monitors your heart rate with a device clipped on your earlobe. You then regulate breathing and follow the instructions provided and feedback is obtained on whether you are achieving synchrony, or what they call “coherence.” As the user becomes more effective in achieving coherence over time, positive physiological and emotional effects develop. HeartMath has been shown, for instance, to reduce systolic and diastolic blood pressure, morning cortisol levels (a stress hormone), and helps people deal with chronic pain. Downside of the HeartMath process: a $249 price tag for the earlobe-USB device.

But this is the age of emerging smartphone apps, including those applied to health. Smartphone apps are perfect for health monitoring. They are especially changing how we engage in biofeedback. An app called Breathe Sync is available that tracks heart rate using the camera’s flash on the phone. By tracking heart rate and providing visual instruction on breathing pattern, the program generates a Wellness Quotient, WQ, similar to HeartMath’s coherence scoring system. Difference: Breathe Sync is portable and a heck of a lot less costly. I paid $9.99, more than I’ve paid for any other mainstream smartphone application, but a bargain compared to the HeartMath device cost.

One glitch is that you need to not be running any other programs in the background, such as your GPS, else you will have pauses in the Breathe Sync program, negating the value of your WQ. Beyond this, the app functions reliably and can help you achieve the health goals of biofeedback with so much less hassle and greater effectiveness than the older methods.

If you are looking for a biofeedback system that provides advantage in gaining control over metabolic health, while also providing a wonderful method of relaxation, Breathe Sync, I believe, is the go-to app right now.

Amber’s Top 35 Health and Fitness Tips

7. November 2014 Amber B (0)
This year I joined the 35 club!  And in honor of being fabulous and 35, I want to share 35 health and fitness tips with you! 

1.  Foam rolling is for everyone and should be done daily. 
2.  Cold showers are the best way to wake up and burn more body fat. 
3.  Stop locking your knees.  This will lead to lower back pain. 
4.  Avoid eating gluten at all costs. 
5.  Breath deep so that you can feel the sides or your lower back expand. 
6.  Swing a kettlebell for a stronger and great looking backside. 
7.  Fat is where it’s at!  Enjoy butter, ghee, coconut oil, palm oil, duck fat and many other fabulous saturated fats. 
8.  Don’t let your grip strength fade with age.  Farmer carries, kettlebells and hanging from a bar will help with that. 
9.  Runners, keep your long runs slow and easy and keep your interval runs hard.  Don’t fall in the chronic cardio range. 
10.  Drink high quality spring or reverse osmosis water. 
11.  Use high quality sea salt season food and as a mineral supplement. 
12.  Work your squat so that your butt can get down to the ground.  Can you sit in this position? How long?
13.  Lift heavy weights!  We were made for manual work,.   Simulate heavy labor in the weight room. 
14.  Meditate daily.  If you don’t go within, you will go with out.  We need quiet restorative time to balance the stress in our life. 
15.  Stand up and move for 10 minutes for every hour your sit at your computer. 
16. Eat a variety of whole, real foods. 
17.  Sleep 7 to 9 hours every night. 
18.  Pull ups are my favorite exercise.  Get a home pull up bar to practice. 
19.  Get out and spend a few minutes in nature.  Appreciate the world around you while taking in fresh air and natural beauty. 
20.  We all need to pull more in our workouts.  Add more pulling movements horizontally and vertically. 
21. Surround yourself with health minded people. 
22. Keep your room dark for deep sound sleep.  A sleep mask is great for that! 
23. Use chemical free cosmetics.  Your skin is the largest organ of your body and all chemicals will absorb into your blood stream. 
24. Unilateral movements will help improve symmetrical strength. 
25. Become more playful.  We take life too seriously, becoming stress and overwhelmed.  How can you play, smile and laugh more often?
26.  Choose foods that have one ingredient.  Keep your diet simple and clean. 
27.  Keep your joints mobile as you age.  Do exercises that take joints through a full range of motion. 
28. Go to sleep no later than 10:30pm.  This allows your body and brain to repair through the night. 
29. Take care of your health and needs before others.  This allows you to be the best spouse, parent, coworker, and person on the planet. 
30.  Always start your daily with a high fat, high protein meal.  This will encourage less sugar cravings later in the day. 
31. Approach the day with positive thinking!  Stinkin’ thinkin’ only leads to more stress and frustration. 
32. You are never “too old” to do something.  Stay young at heart and keep fitness a priority as the years go by. 
33. Dream big and go for it. 
34.  Lift weights 2 to 4 times every week.  Strong is the new sexy. 
35.  Love.  Love yourself unconditionally.  Love your life and live it to the fullest.  Love others compassionately.

To Change, You Need to Get Uncomfortable

25. September 2014 Amber B (0)
Sitting on the couch is comfortable.  Going through the drive thru to pick up dinner is comfortable.  But when you notice that you’re out-of-shape, tired, sick and your clothes no longer fit, you realize that what makes you comfortable is not in align with what would make you happy.   

You want to see something different when you look in the mirror.  You want to fit into a certain size of jeans or just experience your day with more energy and excitement.  The current condition of your life causes you pain, be it physical, mental or emotional.  To escape the pain you are feeling, you know that you need to make changes to your habits that keep you stuck in your current state.  But why is it so hard to make the changes you know that will help you achieve what you want?  

I want to lose weight but….

I want a six pack but…

I want more energy but….

The statement that follows the “but” is often a situation or habit you are comfortable with.  You want to lose weight but don’t have time to cook healthy meals.  So it’s much more comfortable to go through the drive thru instead of trying some new recipes.   New habits often require a learning curve and a bit of extra time in the beginning.  It also takes courage and energy to establish new routines or seek out help.  

Setting out to achieve your goals requires change.  Making changes to establish new habits that support your goals and dreams can be uncomfortable.  Life, as you know it, will be different.  Knowing that fact can be scary, but so can staying in your current condition.  So I’m asking you to take a risk and get uncomfortable so that you can achieve your goals.  

Realize that it takes 21 days to develop a new habit.  I believe it takes triple that amount of time to really make a new habit stick for the long haul.  So for 21 days, you’ll experience some discomfort while you make changes to your old routine and habits.  Depending on what you are changing, discomfort could mean feeling tired, moody, or even withdrawal symptoms.  However, the longer you stick to your new habits the less uncomfortable you start to feel.  The first week is always the worst, but then it gets easier.

Making it through the uncomfortable times requires staying focused on your goals and not caving to your immediate feelings or desires.  I encourage clients to focus on why their goals important to them.  This reason or burning desire to change will help when old habits, cravings, or situations call you back to your old ways.
Use a tracking and a reward system to stay on track.  Grab a calendar, journal or index card to check off or note your daily successes.  Shoot for consistency and not perfection when trying to make changes.  I encourage my clients to use the 90/10 principle of change and apply that to their goal tracking system.  New clothes, a massage, or a day me-retreat are just a few examples of rewards you can use to sticking to your tracking system.  Pick something that really gets you excited.  

Getting support system in place can help you feel more comfortable with being uncomfortable.  Hiring a coach, joining an online support group, or recruiting family and friends can be very helpful when making big changes.  With a support system in place you are not alone in your discomfort.  You’re network is there for you to reach out for help, knowledge, accountability or camaraderie when you feel frustrated and isolated.  

I’ve helped hundreds of people change their bodies, health and lives of the eleven years I’ve worked as a trainer and coach.  I know it’s hard, but I also know that if they can do it, so can you.  You just need to step outside of your comfort zone and take a risk. Don’t let fear create uncomfortable feelings that keep you stuck in your old ways.  Take that first step and enjoy the journey of reaching your goals and dreams.

The 3 Best Grain Free Food Swaps to Boost Fat Burning

25. September 2014 Lisa G (0)
You can join others enjoying substantial improvements in their health, energy and pant size by making a few key, delicious substitutions to your eating habits.  This is possible with the Cureality nutrition approach, which rejects the idea that grains should form the cornerstone of the human diet.  

Grain products, which are seeds of grasses, are incompatible with human digestion.  Contrary to what we have been told for years, eating healthy whole grain is not the answer to whittle away our waists.  Consumption of all grain-based carbohydrates results in increased production of the fat storage hormone insulin.  Increased insulin levels create the perfect recipe for weight gain. By swapping out high carbohydrate grain foods that cause spikes in insulin with much lower carbohydrate foods, insulin release is subdued and allows the body to release fat.

1. Swap wheat-based flour with almond flour/meal

  • One of the most dubious grain offenders is modern wheat. Replace wheat flour with naturally wheat-free, lower carbohydrate almond flour.  
  • Almond flour contains a mere 12 net carbs per cup (carbohydrate minus the fiber) with 50% more filling protein than all-purpose flour.
  • Almond flour and almond meal also offer vitamin E, an important antioxidant to support immune function.

2. Swap potatoes and rice for cauliflower

  • Replace high carb potatoes and pasta with vitamin C packed cauliflower, which has an inconsequential 3 carbs per cup.  
  • Try this food swap: blend raw cauliflower in food processor to make “rice”. (A hand held grater can also be used).  Sautee the “riced” cauliflower in olive or coconut oil for 5 minutes with seasoning to taste.
  • Another food swap: enjoy mashed cauliflower in place of potatoes.  Cook cauliflower. Place in food processor with ½ a stick organic, grass-fed butter, ½ a package full-fat cream cheese and blend until smooth. Add optional minced garlic, chives or other herbs such as rosemary.
3. Swap pasta for shirataki noodles and zucchini

  • Swap out carb-rich white pasta containing 43 carbs per cup with Shirataki noodles that contain a few carbs per package. Shirataki noodles are made from konjac or yam root and are found in refrigerated section of supermarkets.
  • Another swap: zucchini contains about 4 carbs per cup. Make your own grain free, low-carb noodles from zucchini using a julienne peeler, mandolin or one of the various noodle tools on the market.

Not so fast. Don’t make this mistake when going gluten free!

25. September 2014 Lisa G (0)
Beginning last month, the Food and Drug Administration began implementing its definition of “gluten-free” on packaged food labels.  The FDA determined that packaged food labeled gluten free (or similar claims such as "free of gluten") cannot contain more than 20 parts per million of gluten.

It has been years in the making for the FDA to define what “gluten free” means and hold food manufactures accountable, with respect to food labeling.  However, the story does not end there.

Yes, finding gluten-free food, that is now properly labeled, has become easier. So much so the market for gluten-free foods tops $6 billion last year.   However, finding truly healthy, commercially prepared, grain-free foods is still challenging.

A very common mistake made when jumping into the gluten-free lifestyle is piling everything labeled gluten-free in the shopping cart.  We don’t want to replace a problem: wheat, with another problem: gluten free products.

Typically gluten free products are made with rice flour (and brown rice flour), tapioca starch, cornstarch, and potato flour.  Of the few foods that raise blood sugar higher than wheat, these dried, powdered starches top the list.

 They provide a large surface area for digestion, thereby leading to sky-high blood sugar and all the consequences such as diabetes, hypertension, cataracts, arthritis, and heart disease. These products should be consumed very rarely consumed, if at all.  As Dr. Davis has stated, “100% gluten-free usually means 100% awful!”

There is an ugly side to the gluten-free boom taking place.  The Cureality approach to wellness recommends selecting gluten-free products wisely.  Do not making this misguided mistake and instead aim for elimination of ALL grains, as all seeds of grasses are related to wheat and therefore overlap in many effects.

3 Foods to Add to Your Next Grocery List

25. September 2014 Lisa G (0)
Looking for some new foods to add to your diet? Look no further. Reach for these three mealtime superstars to encourage a leaner, healthier body.

Microgreens

Microgreens are simply the shoots of salad greens and herbs that are harvested just after the first leaves have developed, or in about 2 weeks.  Microgreen are not sprouts. Sprouts are germinated, in other words, sprouted seeds produced entirely in water. Microgreens are grown in soil, thereby absorbing the nutrients from the soil.

The nutritional profile of each microgreen depends greatly on the type of microgreen you are eating. Researchers found red cabbage microgreens had 40 times more vitamin E and six times more vitamin C than mature red cabbage. Cilantro microgreens had three times more beta-carotene than mature cilantro.

A few popular varieties of microgreens are arugula, kale, radish, pea, and watercress. Flavor can vary from mild to a more intense or spicy mix depending on the microgreens.  They can be added to salads, soup, omelets, stir fry and in place of lettuce.  

Cacao Powder

Cocoa and cacao are close enough in flavor not to make any difference. However, raw cacao powder has 3.6 times the antioxidant activity of roasted cocoa powder.  In short, raw cacao powder is definitely the healthiest, most beneficial of the powders, followed by 100% unsweetened cocoa.

Cacao has more antioxidant flavonoids than blueberries, red wine and black and green teas.  Cacao is one of the highest sources of magnesium, a great source of iron and vitamin C, as well as a good source of fiber for healthy bowel function.
Add cacao powder to milk for chocolate milk or real hot chocolate.  Consider adding to coffee for a little mocha magic or sprinkle on berries and yogurt.




Shallots

Shallots have a better nutrition profile than onions. On a weight per weight basis, they have more anti-oxidants, minerals, and vitamins than onions. Shallots have a milder, less pungent taste than onions, so people who do not care for onions may enjoy shallots.

Like onions, sulfur compounds in shallot are necessary for liver detoxification pathways.  The sulfur compound, allicin has been shown to be beneficial in reducing cholesterol.  Allicin is also noted to have anti-bacterial, anti-viral, and anti-fungal activities.

Diced then up and add to salads, on top of a bun less hamburger, soups, stews, or sauces.  Toss in an omelet or sauté to enhance a piece of chicken or steak, really the possibilities are endless.

3 Band Exercises for Great Glutes

15. August 2014 Amber B (0)
Bands and buns are a great combination.  (When I talk about glutes or a butt, I use the word buns)  When it comes to sculpting better buns, grab a band.   Bands are great for home workouts, at gym or when you travel.  Check out these 3 amazing exercises that will have your buns burning. 

Band Step Out

Grab a band and place it under the arch of each foot.  Then cross the band and rest your hands in your hip sockets.  The exercise starts with your feet hip width apart and weight in the heels.  Slightly bend the knees and step your right foot out to the side.  Step back in so that your foot is back in the starting position.  With each step, make sure your toes point straight ahead.  The tighter you pull the band, the more resistance you will have.    You will feel this exercise on the outside of your hips. 

Start with one set of 15 repetitions with each foot.  Work on increasing to 25 repetitions on each side and doing two to three sets.



Band Kick Back

This exercise is performed in the quadruped position with your knees under hips and hands under your shoulders.    Take the loop end of the band and put it around your right foot and place the two handles or ends of the band under your hands.  Without moving your body, kick your right leg straight back.  Return to the starting quadruped position.  Adjust the tension of the band to increase or decrease the difficulty of this exercise. 

Start with one set of 10 repetitions with each foot.  Work on increasing to 20 repetitions on each side and doing two to three sets. 



Band Resisted Hip Bridge

Start lying on your back with feet hip distance apart and knees bent at about a 45-degree angle.  Adjust your hips to a neutral position to alleviate any arching in your lower back.  Place the band across your hipbones.  Hold the band down with hands along the sides of your body.  Contract your abs and squeeze your glutes to lift your hips up off the ground.  Stop when your thighs, hips and stomach are in a straight line.  Lower you hips back down to the ground. 

Start with one set of 15 repetitions.  Work on increasing to 25 repetitions and doing two to three.  Another variation of this exercise is to hold the hip bridge position.  Start with a 30 second hold and work up to holding for 60 seconds.

Wheat belly

23. July 2007 William Davis (31)
You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

If health won't motivate them, maybe money will

As part of our ongoing effort to educate everyone about the value of heart scans and how they can serve to start a program of heart disease prevention (or elimination), we occasionally distribute press releases on one facet of this discussion or another.

Here's the one we released on our Cost Calculator, the one we developed that showed that $20 billion would be saved annually just by applying the program to men, ages 40-59.




Accurate Detection and Prevention of Heart Disease Can Reduce Healthcare Costs, According to New Cost Analysis

A new cost analysis developed by cardiologist Dr. William Davis and his colleagues suggests that healthcare costs can be reduced by billions of dollars with the application of a simple program for heart disease detection and prevention.

Milwaukee, WI (PRWEB) July 23, 2007 -- Billions of dollars in healthcare could be saved every year by applying a simple program of heart disease detection and prevention on a wide scale in the U.S., suggests a new cost analysis developed by cardiologist Dr. William Davis and colleagues. Davis and his colleagues are the developers of the Track Your Plaque program for heart disease detection and prevention.

In the next 24 hours, 10,000 major heart procedures will be performed in hospitals across the U.S. The tab for this bill will top $400 billion in 2007 alone, nearly twice the sum spent on the war on cancer.

As costs escalate at an alarming rate, tools for prevention of disease are also advancing. While drugs like Lipitor® make headlines and dominate direct-to-consumer TV ads, a quiet revolution is taking place among physicians and the public eager to find better answers, some of which also pose opportunities for stretching the healthcare dollar.

“We’re essentially throwing away billions of dollars each and every year by ignoring the savings power of preventive strategies for heart disease,” proclaims Davis, a Milwaukee cardiologist. Davis is author of several books on heart disease detection and prevention, has been a vocal advocate for preventive strategies and is founder of www.cureality.com.

Davis and his colleagues developed a cost model to predict how much money could be saved by the adoption of new preventive strategies on a broad scale in the U.S. “The cost savings are startling. If males in the 40–59-year-old age group, for instance, were to undergo a simple CT heart scan for early detection of coronary heart disease, followed by a purposeful yet focused program of prevention using widely available tools, our cost model shows that we would save the American public over $20 billion annually. Extending this calculation to the broader population would multiply savings several-fold.”

Heart care is already the single largest healthcare category in the U.S. As costs go up by double-digit percentages, fewer people can afford healthcare. Those who can afford it spend an increasingly greater portion of their disposable income to maintain it. The Agency for Healthcare Research and Quality predicts that, at the current rate of growth, healthcare costs will balloon to absorb 20 percent of American Gross Domestic Product (GDP), about $4 trillion, in the next 10 years.

Davis points out that reducing the annual U.S. expenditure for heart disease by 20 to 30 percent could save between $80 and $120 billion each year. That marginal savings exceeds the sum the U.S. spends on the domestic war on terror.

Davis and his group have dubbed the conventional procedure-based approach to heart disease management the “crash and repair model” because of its focus on urgent procedural intervention that takes place in hospitals.

The crash and repair model is costly. According to the American Heart Association, a heart catheterization (performed 3,553 times per day, seven days a week) costs an average of $24,893; a coronary bypass operation (performed 1,170 times every day, seven days a week) costs an average of $67,823 (hospital costs, 2004, the latest year for which data are available). These figures don’t incorporate long-term costs incurred in the years following the procedure or time lost from work.

The relatively high payment to physicians and hospitals for performing high-tech heart procedures provides a disincentive to redirect patients to a less costly prevention model. The exceptional costs of high-tech, high-ticket heart procedures would become increasingly unnecessary if better heart disease preventive practices were delivered on a broad scale. “Like seatbelts, preventive measures for heart disease are more cost effective and extract a far lower toll in human suffering than the ‘crash and repair’ approach. Our cost calculations bear out the enormous savings possible. In fact, all of the tools necessary to deliver a method of early heart disease detection and prevention are already available throughout the U.S. We’ve just got to encourage physicians and the public to take advantage of them.”

Track Your Plaque is an informational and educational Web site devoted to showing people how CT heart scans can be used as a starting point for a program of heart disease prevention and reversal.

What role calcium supplements?

22. July 2007 William Davis (8)
A frequent question in the Track Your Plaque program is whether taking calcium supplements to reduce risk for osteoporosis adds to calcium in arteries and raises CT heart scan scores.

No, calcium supplementation does not add to coronary calcium. Thankfully, there is some wisdom to calcium metabolism. Calcium deposition or resorption is under independent local control in bone, as it is in the artery wall. Taking calcium has no effect on calcium deposition in your coronary arteries.

However, there's a lot more to it. Taking calcium has only a modest effect on bone health. Most women can only hope to slow or stop calcium loss from bone by taking calcium supplements. Calcium supplements do not increase bone calcium. The reason why calcium supplementation works at all is, when calcium is absorbed into the blood, it provides a feedback signal to the parathyroid gland to shut down parathyroid hormone production, the hormone responsible for extracting calcium from bone. But the calcium itself does not end up deposited in bone.

Likewise, calcium supplements have essentially no effect on the artery wall. But vitamin D controls calcium absorption and, curiously, appears to exert a dramatic effect on calcium depostion in coronary arteries. In fact, I would credit vitamin D as among the most important factors in regulating arterial health that I've encountered in a long time.

Thus, bone health and arterial health do indeed intersect via calcium, but not through calcium supplements. Instead, the control exerted by vitamin D connects the seemingly unconnected processes.

Vitamin K2 provides another unexpected juxtaposition of the two processes. Deficiency of K2, which is proving to be a lot more common than previously thought, permits an enzyme in bone to exert unrestrained calcium extraction. Deficiency of K2 in artery walls allow another enzyme to deposit calcium and grow plaque without restraint. Yet another intersection between bone health and coronary health that involves calcium, but as a passive participant.

Stay tuned for a comprehensive Track Your Plaque Special Report on these topics coming in the next couple of weeks. I'm very excited about the emerging appreciation of calcium as an active ingredient in plaque, not a dumb, passive marker as previously thought. Vitamins D3 and K2 are among the keys to this phenomenon.

"Heart scans" are not always heart scans

18. July 2007 William Davis (6)
Beware of the media reports now being issued that warn that "CT heart scans" pose a risk for cancer.

One report can be viewed at
http://www.webmd.com/cancer/news/20070717/ct-heart-scan-radiation-cancer-risk.

This was triggered by a Columbia University study of risk for cancer based on the dose of radiation used in CT coronary angiograms. Theoretically, exposure to the radiation dose of CT coronary angiography can raise risk for cancer by 1 in 143 women if radiated in their 20s just from that single exposure.

If you've been following the Track Your Plaque discussion, as well as my diatribes in the Heart Scan Blog, you know that the media got it all wrong. The "heart scans" they are referring to are not the same as the heart scans that we discuss for the Track Your Plaque program.

A conventional heart scan (of the sort we refer to) exposes the recipient to 4 chest x-rays of radiation if an EBT device is used, around 8-10 chest x-rays of radiation if a 64-slice CT scanner is used. For the quality of information we obtain from these screening heart scans, we feel that it's an acceptable exposure.

The "heart scan" this study and subsequent reports refer to is not truly a screening heart scan, but a CT coronary angiogram, or CTA. CTAs are performed on the same CT or EBT devices, but involve far more radiation. CTA exposes the recipient to about 100 chest x-rays of radiation on a 64-slice device (more or less, depending on the way it is performed.) Just a couple of years ago, some centers were performing CTA on 16-slice devices, a practice I and the Track Your Plaque program vocally opposed, since up to 400 chest-rays of radiation were required! I even called a number of centers advising them that they were putting the public in jeopardy. CTAs also require injection of x-ray dye, just like any conventional angiogram.

CTA on 64-slice CT scanners require the same radiation exposure as a conventional heart catheterization, an issue glossed over in most conversations. In other words, the test that many of my colleageus so casually recommend poses a similar risk.

The message: the test I advocate for screening for coronary heart disease is a CT or EBT heart scan, not a CT coronary angiogram. CTA is a useful test and will get better and better as the engineers discover ways to reduce radiation exposure. But, in 2007, CTA is a diagnostic device, not a screening device. If you require an abdominal CT scan because your doctor suspects pancreatic cancer, or a CT scan of the brain because you might have a life-threatening aneurysm causing double-vision or seizures, it would be silly to not undergo the scan because of long-term and theoretical cancer risk.

But undergoing a CT coronary angiogram for screening purposes is ridiculous with present technology. I've said it before and I will say it--shout it--again:

CT coronary angiograms are not screening procedures; they are diagnostic procedures that should be taken seriously and do indeed pose measurable risk for cancer, a risk that is presently unacceptable for a screening test.

You wouldn't undergo a mammogram to screen for breast cancer if it exposed you to 100 chest x-rays of radiation, would you? Screening tests should be safe, reliable, accurate, and inexpensive. CT coronary angiography is none of these things. Genuine heart scans--the kind the Track Your Plaque program talks about and relies on--is all of those things.

Heavy traffic and heart scans

17. July 2007 William Davis (4)
A German study just reported in Circulation showed a graded response of EBT heart scan scores and proximity to traffic.

Living 50 meters (around 150 feet) from traffic increased the likelihood of a higher coronary calcium score by 63% compared to those living 200 meters (around 600 feet or two football fields) away from traffic.

A sample news story can be found at http://healthday.com/Article.asp?AID=606431.

The German investigators speculated that either the heightened exposure to exhaust fumes and/or the increased stress triggered by the constant noise might be the culprits behind the phenomenon.

I think the study is interesting in a number of ways from the Track Your Plaque viewpoint:

--Sometimes, there are factors that extend beyond lipoproteins, vitamin D restoration, optimism vs. pessimism, etc. that influence heart scan scoring. Are these factors powerful enough to overcome the adverse effects of traffic or other environmental effects? Can your proximity to traffic make or break your heart scan score-controlling efforts? This remains to be established.

--How much of a role does the stress issue play? Is this just a variation of the optimism vs. pessimism theme? I know when I'm in traffic in a car or on a bicycle, it often feels like I am at the mercy of hordes of people in a hurry, the soccer Moms on cell phones, applying makeup and eating, the hormonal teenager, the occasional drunk. Living in the midst of it must be demoralizing, a sense that you are lost in a sea of uncaring humanity stripped of individuality. When I look outside my den window right now, I see the lawn that I cut and water and the flowers and evergreen trees I've planted over the years. It provides a sense of life, belonging, and earth. What if instead I saw anonymous cars buzzing by, dozens of unfamiliar faces every minute, none of which plays any palpable role in my life?

--This simple observation will add to the healthy-consciousness and Green movements, since it is just one more piece of evidence that congestion and urbanization do indeed take their toll. In an obtuse way, I think this is one step closer to increasing disillusionment over the "over-processing" of human experience: processed foods, depersonalization and alienation in neighborhoods and homes, the dissolution of the American family.

Lastly, notice how the conversation about CT (in this case, EBT) heart scanning has seamlessly worked its way into conversation? Just ten years ago, a long-winded explanation would have been required in press reports on just what CT heart scanning was. Now, the information is presented and--well, we all know what heart scanning is, right?

A small study but one that comes at an important time. Good things will come from this one study. It will work its way into discussions about where to locate schools, how to situate homes in relation to heavy traffic, it will help "legitimize" this wonderful tool called heart scanning. How many medical tests beyond blood work can be easily performed in 4500 study participants?

I always like to take some simple observation and see how it fits into developing trends. Few studies or other human-generated experiences by themselves change the world. Instead, it happens in little incremental bits and pieces.

Digging for the truth

15. July 2007 William Davis (9)
I remain continually amazed how difficult it can be to gain an understanding of what is true and what is not true. I am particularly worried about the messages provided by agencies that stand to make enormous gains by persuading us to believe their version of the "truth".

For a moment, let's strip away the charitable covers of some financially-motivated organizations and see what they really look like:


Hospitals: The dream of hospitals is to shift the proportion of patients towards those with the most profitable diseases in well-insured patients. Heart disease is among the best paying diseases. HOSPITALS WANT YOU TO HAVE HEART DISEASE.

Doctors: Many (though not all) want to deal with diseases that pay well. Implanting a stent can pay several thousand dollars. Putting in a defibrillator can likewise pay handsomely, even better than stents. DOCTORS WANT TO STEER YOU TOWARDS PROCEDURES THAT REIMBURSE GENEROUSLY. Talk is cheap and pays poorly. Heart scans? Useless, since they're cheap. CT angiography? Now we're talking! $1800 dollars is a lot more interesting than $200 or so for a simple heart scan. CT angiograms also lead to catheterization, stents, hospitalizations.

Drug manufacturers: The holy grail for drug manufacturers is a chronic condition that is present in large numbers of people. An antibiotic, for instance, is a drug manufacturers waste of time: Short courses of treatment in relatively few people. Cholesterol drugs, blood pressure drugs, drugs to modify personality or some aspect of behavior--these you take for years, decades, or a lifetime, and millions are persuaded they need them. DRUG COMPANIES WANT CHRONIC CONDITIONS (WHETHER OR NOT THEY'RE DISEASES) IN PEOPLE WHO SURVIVE FOR A LONG TIME, NOT SICK PEOPLE.

Supplement manufacturers: What don't we need in the eyes of sellers of nutritional supplement? While a program like Track Your Plaque makes liberal use of supplements in a focused and, I believe, rational way, supplement sellers want you to take dozens or preparations of dubious value: milk thistle, hawthorne, ribose, hoodia, silymarin, hydroxycitric acid . . . Unlike the larger ambitions and bigger money of the pharmaceutical industry, the supplement industry is often driven by the momentary craze and the quick payoff. THE SUPPLEMENT INDUSTRY IS LOOKING FOR SUCKERS.

Food manufacturers: The holy grail for the food industry are foods that have high markups, are convenient (e.g., eaten right out of the box or package), and are purchased repeatedly. Even better, if a health claim can be added, it can ride the current wave of the public's health consciousness. Thus, Cocoa Puffs can be labeled "Heart Healthy". How about foods that have addictive potential and virtually ensure repeat sales? Eat some and you want more within 2-4 hours! As nutritionist Marion Nestle says, the mantra of the foods industry is "Eat More". It is my firm conviction that the epidemic of obesity in the U.S. is not due to laziness, video games, and computers. It is the fault of food manufacturers. FOOD MANUFACTURERS WANT US FAT AND HUNGRY AND WANT US TO STAY THAT WAY. What pays better, a 110 lb vegetarian woman who shops at the farmer's market and buys locally produced foods, or the 260 lb glutenous and always-hungry woman who fills her supermarket shopping cart with 15 cents worth of flour and sugar priced at $4.59 (cleverly disguised as a healthy breakfast cereal), instant mixes, convenient meals, energy bars, and chips?

Government agencies: User fees for the FDA paid by drug companies have caused the FDA to be beholden to drug company pressures. The USDA, charged with crafting the food pyramid, was created to support the farm industry and distributors of their products, not to disseminate public health. The food pyramid is the watered down end result of food industry lobbying and threats, not the scientific advice of nutritionists. GOVERNMENT AGENCIES SERVE INDUSTRY FIRST, THE PUBLIC SECOND.

Health websites: Read popular websites like WebMD for information and the conversation quickly steers towards drugs. "Natural treatments for cholesterol" talks about reducing saturated fat and then gushes about the wonders of statin drugs. Guess where 80% of WebMD's revenues come from? Yup, the drug industry. The same goes for many magazines, TV shows, and other media. MEDIA IS OFTEN THE TOOL OF BIG INDUSTRY.



I'm sounding like a conspiracy theorist. I don't believe that I am, but I am skeptical of the messages we often receive from the media, advertisements, news reports, websites, etc. It's left to you and me to use our judgment and decide what is truth and what is someone's version of a message crafted towards their hidden agenda.

I am hoping that the real truth will grow through a wiki-like phenomena driven and supervised by a collective knowledge that we all contribute towards. That will happen, most likely, on the internet. Just as Wikipedia overtook the revered Encylopedia Britannica in the blink of an eye at far less cost yet with greater depth and equivalent accuracy, so will it happen in health information. I'm uncertain of the eventual form this health-wiki will take, but it will shatter many smug and deeply-entrenched powers that at present continue to profit from mis-information.

A new Track Your Plaque record: 63% reduction

14. July 2007 William Davis (3)
Stress can booby-trap the best efforts at reducing your CT heart scan score.

But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction.

Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record.

I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!

Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!)

The Ornish diet made me fat

13. July 2007 William Davis (16)
I got that kind of question today that tempts me to roll my eyes and say, "Not again!"

"If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease.

I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices.

What happened?

I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day.

Hundreds of my patients suffered similar phenomena.

Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.

So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.

Keep your eyes open for the New Track Your Plaque Diet.

Do lower heart scan scores grow faster?

11. July 2007 William Davis (0)
If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score.

If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points.

This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year.

In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)

If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score.

Mr. Salazar: Check your Lp(a)

9. July 2007 William Davis (8)
Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.

At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending.

Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye.

But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.

I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).

It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.

I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why?

The answer is almost certain to be Lp(a).
