I don't care about hard plaque!

25. September 2006 William Davis (10)

I ran into a cardiology colleague this weekend. He was aware of my interest in CT heart scanning and plaque reversal.

Out of the blue, he declared "I don't care about hard plaque! I only care about soft plaque." He then proceeded to describe to me how everyone--EVERYONE--needs a CT coronary angiogram to identify "soft plaque".

Is there any truth to this view? Are we only identifying "hard plaques" by focusing on calcium and calcium scores on simple CT heart scans?

Several issues deserve clarification. First of all, CT heart scans don't identify hard plaque. They identify total plaque. Because calcium is a component of the majority of atherosclerotic plaque, comprising approximately 20% of its volume, a calcium "score" can be used to indirectly quantify total plaque, both "hard" and "soft".

Anyone cardiologist who performs a lot of the procedure, intracoronary ultrasound, knows that most human plaque is also not purely soft or hard, it is mixture of both. (I've been performing this procedure since 1995.) Quantifying only soft or only hard plaque is therefore only possible in theory, not in practice.

I believe my colleague does have a valid point in one regard, however. There is indeed a small percentage of people, probably around 5% of all people who have CT heart scans, who have scores of zero yet have a modest quantity of pure "soft" plaque. These people may be misled by having a zero score. How can these people benefit from better information?

Several ways. First, people like this tend to have very high LDL cholesterols, generally 180 mg/dl or greater. They may have a very worrisome family history, e.g., father with heart attack in his 30s or 40s. This small proportion of people with zero heart scan scores may benefit from receiving X-ray dye with their heart scan, i.e., a CT coronary angiogram. Keep in mind that we're assuming everyone is without symptoms, also. If symptoms are part of the picture, everything changes.

But should everybody get a CT coronary angiogram? I don't believe so. A CT coronary angiogram involves far more radiation exposure, greater expense (usually $1800 to $4000), and, with present day technology, does not yield quantitative (measurable) information that is useful for longitudinal use for repeated scans. You don't want to undergo yearly CT coronary angiograms, for instance.

Stay tuned for more on this issue. In the meantime, I continue to try and inform my colleagues about what is right, what is wrong, what is preferable for patient safety and yields truly empowering information, and try to impress on them that the practice of cardiology is not just about enriching their retirement accounts.

Try an experiment in a wheat-free diet

23. September 2006 William Davis (1)

Years back, I'd heard some people argue that wheat-based products were detrimental to health. At the time, I thought they were nuts. After all, wheat is the principal ingredient in a huge number of American staples like breakfast cereals and bread.

What changed my mind was the low-fat movement of the 1980s and 1990s. Proponents of low-fat diets claim that heart disease is caused by excess fat in the diet. A diet that is severely restricted in fat therefore might cure or reverse heart disease.

But low-fat diets evolve into high-carbohydrate diets. This nearly always means an over-reliance on wheat products. People will say to me "I had a healthy breakfast: shredded wheat cereal in skim milk and two slices of whole wheat toast." Yes, it is low-fat, but is it healthy?

Absolutely not. Followers of the Track Your Plaque program know that low-fat diets ignite the formation of small LDL particles (a VERY potent trigger of coronary plaque growth), drops HDL, raises triglycerides, causes resistance to insulin and thereby diabetes, raises blood pressure. They also make you fat, with preferential accumulation of abdominal visceral (intestinal lining) fat.

Look at people with gluten enteropathy, a marked intolerance to wheat products that results in violent bowel problems, arthritis, etc. if unrecognized. These people, if the diagnosis is made early, are strikingly slender and commonly unusually healthy otherwise. There's a message here.

If you need convincing, try an experiment. Eliminate--not reduce, but eliminate wheat products from your diet, whether or not the fancy label on the package says it's healthy, high in fiber, a "healthy low-fat snack", etc. This means no bread, pasta, crackers, cookies, breads, chips, breading on chicken, rolls, bagels, cakes, breakfast cereal...Whew!

You won't be hungry if you replace the lost calories with plentiful raw almonds, walnuts, pecans, sunflower and pumpkin seeds; more liberal use of healthy olive oil, canola oil and flaxseed oil; adding ground flaxseed and oat bran to yogurt, cottage cheese, etc.; and more lean proteins like lean beef, chicken, turkey, and fish.

I predict that, not only will you lose weight, sometimes dramatically, but you will feel better: more energy, more alertness, sleep better, less moody. Time and again, people who try this will tell me that the daytime grogginess they've suffered and lived with for years, and would treat with loads of caffeine, is suddenly gone. They cruise through their day with extra energy.

Success at this can yield great advantage for your heart scan score control and reversal efforts. It will give you greater control over small LDL and pre-diabetic patterns, in particular.

Bigger, faster plaque reversal

22. September 2006 William Davis (0)

Perhaps it's too early to tell whether it's true, but believe that we're seeing coronary plaque reversal--i.e., reduction of CT heart scan score--that is BIGGER and FASTER than ever before. We are now witnessing 20-30% reductions in score, even in the first year.

Early in our experience, I was thrilled with a slowing of plaque growth. Recall that coronary plaque grows at the rate of 30% per year. We would often seen slowing to 10-15% per year in the first year, then a levelling off to little or no increase in the 2nd or 3rd year. Regression, or reduction of score, was less common.

Now, with some further tweaking of our program, we are seeing these large magnitudes of coronary plaque reversal routinely. Not in everybody, of course. There are exceptions that mostly includes people who are less motivated and occasional people with more difficult to control lipoprotein patterns.

I believe that part, or perhaps most, of our recent success is from normalizing blood levels of 25-OH-vitamin D3 levels to 50-70 ng/ml. I'm unable to tell you why this occurs, but I am convinced that it has added huge advantage. Raising blood vitamin D levels to normal carries enormous implication: reduction of colon and prostate cancer risk, reduction of blood pressure, sensitization to insulin, prevention of arthritis and multiple sclerosis, and--I believe--control over coronary plaque calcification and growth.

Watch for a profile of one of our latest success stories, a physician who was experiencing 20% per year plaque growth three years in a row until he followed the Track Your Plaque approach and promptly experienced an 18% reduction in heart scan score.

I need to do more procedures!

22. September 2006 William Davis (0)

I sat next to a cardiology colleague of mine last evening at a dinner. He was lamenting the fact that, because of changes in hospital affiliations of his several-member cardiology group, he'd seen a drop in the volume of heart catheterizations he was performing.

"I'm used to doing 5 cases a day! Now I'm down to 3 or 4 a day." He went on to tell me how he's working to increase his volume. "I'm branching out into doing carotid stents and anything I can find in the legs." He also described how he was cultivating referring physicians to send him more procedural patients.

Now, this colleague, I believe, is a hard-working, conscientious physician. But his attitude reflects the perverse logic of many physicians: I need to do more procedures, not because it benefits patients, but because that's what I want to do--to be busy, make more money, acquire more experience, build my ego, etc.

Doing more procedures has nothing to do with an altruistic goal of doing more good for society. It is purely for selfish reasons. Beware of this shockingly common, pervasive attitude. There's a proper time and place for heart procedures, or any procedure, for that matter. But feeding your doctor's ambitions is not a good reason.

Fast food and quick plaques

20. September 2006 William Davis (0)

Such was the title of Dr. William Roberts' editorial back in 1987 discussing the health effects of fast foods.

If you need a graphic illustration of the extraordinarily damaging health effects of fast foods, take a look at trends in mainland China. A recent editorial in the American Journal of Cardiology written by Dr. Tsung Cheng of George Washington University makes several points:

--The popularity of fast food in China is booming, with Chinese now more likely than Americans to eat in a fast food restaurant. Each week, 41% of Chinese eat in a fast food restaurant at least once, compared to 35% in the U.S.

--Average total cholesterol levels have skyrocketed from 150 mg/dl in 1958 to 230 mg/dl in 2003.

--50% of Chinese with normal blood pressure in 1992 are now hypertensive.

--Hospitalization for heart disease rose from the 5th most common diagnosis to #1, now constituting nearly 50% of all hospital admissions.

McDonald's and KFC dominate the fast food landscape in China, but up and coming competitors are growing at exponential rates. A media conversation that will surely be reported in the near future is the boom in obesity and diabetes in China as these trends express themselves in weight gain, as it has in the U.S.

I hope you've all seen the entertaining but frightening documentary, Supersize Me chronicling the travails of 30-something Morgan Spurlock as he eats all his meals for one month at McDonald's restaurants in 20 cities. Though focusing on McDonald's, the movie is about a lot more than that. It paints a picture of how fast food as well as food manufacturers in general have changed--distorted--our eating habits.

If you haven't yet seen it, I would urge you to do so and watch it with the rest of the family. My kids (ages 8, 12, and 14) were shocked (and entertained) and they haven't set food in a fast food restaurant since.

But fish oil is too drastic!

20. September 2006 William Davis (0)

Ted is a 74-year old physician, still conducting a busy practice. He came to me because of some vague fatigue and breathlessness. He also got himself a CT heart scan. His score: 1277.

When he came to my office, he clearly became breathless with just minimal effort. A stress test confirmed an area of much reduced blood flow to the front of his heart muscle. A heart catheterization identified a severe blockage of 95% in the left anterior descending artery and a stent was inserted. This resulted in relief of Ted's symptoms.

When Ted returned to the office after his discharge from the hospital, I advised him that some major changes in his prevention program were overdue. "After all, Ted, you were lucky this time. You were provided some warning. It doesn't always work that way." So I advised Ted to make a number of changes in his diet (he was following an old-fashioned, and quite self-destructive, low-fat diet), have lipoproteins assessed to identify hidden causes of coronary plaque, and take fish oil.

"Fish oil? I don't think so. That's pretty drastic!" he exclaimed. He felt that all the nutrition he needed was contained in the food he ate. Even after several lipoprotein abnormalities were uncovered like small LDL and excessive after-eating (post-prandial) patterns, he still resisted any changes. "I'm going to just wait and see how I feel. But I will take aspirin."

Such is the state of mind of the older physician: procedures are okay, low-fat diets prevent heart disease, and the Beatles are touring America. But fish oil? No way!

Unfortunately, Ted's attitude encapsulates the attitudes of many of my medical colleagues who don't share the excuse of age. They still practice the woefully outdated ways of physicians like Ted, clinging to notions of "balanced diets", nitroglycerin representing a rational treatment for coronary disease, and adequate rest being curative for heart conditions.

The world is changing. We're entering an exciting age of self-empowerment. The ridiculous notions of health practiced in the last half of the 20th century are withering and dying. Poor Ted. He must view the current healthcare landscape as increasingly incomprehensible to a guy who started out delivering babies at home. Perhaps, in some respects his world was better. But, in coronary disease prevention, attitudes like this need to go the way of steam engines and racial segregation--good riddens!

A curious case of coronary plaque regression and progression

18. September 2006 William Davis (0)

John received a coronary stent in 2003 following a small heart attack. The artery causing the heart attack was a diagonal artery, a branch of the important left anterior descending coronary artery (in the front of the heart). His cardiologist at the time advised him, "Take Lipitor and we'll do stress tests every year. Come back if you have any more chest pain." That was the full extent of John's preventive care.

He came to me for a second opinion and, naturally, we enrolled him in our program. We began by obtaining a CT heart scan score, though we had to exclude the stented diagonal artery. His score: 471. At age 51 and physically active, John had 7 additional abnormal lipoprotein patterns identified. We counseled John on better approaches to food choices, his weight target, fish oil, and correction of all lipoprotein patterns.

Two years later, John's repeat heart scan score: 511 . John was initially disappointed with the increase. But a closer look yielded something entirely different: the right coronary artery and circumflex (no stents) showed 20-30% reduction in their scores. The increase in total score was entirely due to substantial increase in score just outside the stent, in the left anterior descending artery. In other words, all of the increase in score was due to growth of a plaque at the mouth of the stent in the diagonal artery.

This is curious: profound regression of plaque with a big drop in score in the "un-instrumented" arteries, but tremendous growth of plaque and an increase in score in the "instrumented", or stented, artery, all in the same person's heart.

I don't know how controllable this specific situation in the left anterior descending and stented diagonal will be, and I'm unaware of any specific strategies to impact on this situation. The whole world of tissue growth within or around stents is littered with high hopes followed by failures. The drug-coated stents have been the only partial solution to this problem, though that's precisely the sort of stent John received.

Is there a message here? The message I take from this is that you and I should work like mad to keep from receiving a stent. Once they're implanted, we have less control over our coronary future. We can indeed regress ("reverse") coronary plaque. But we may not be able to regress the sort of tissue that grows in response to a stent implantation.

When is a heart scan score of 400 better than 200?

13. September 2006 William Davis (0)

Imagine two people.

Tom is a 50-year old man. Tom's initial heart scan score is 500--a bad score that carries a 5% or more risk for heart attack per year.

Harry is also 50 years old. His heart scan score is 100--also a concerning score but not with the same dangers of Tom's much higher score.

Tom follows a powerful heart disease prevention program like the Track Your Plaque program. He achieves the 60:60:60 lipid targets; chooses healthy foods; takes fish oil; raises his blood vitamin D level to >50 ng/ml, etc. One year later, Tom's heart scan score is 400, a 20% reduction from his starting score.

Harry, on the other hand, doesn't understand the implications of his score. Neither does his doctor. He's casually provided a prescription for a cholesterol drug by his doctor but nothing else. One year later, Harry's heart scan score is 200, a doubling (100% increase) of the original score.

At this point, we're left with Tom having a score of 400, Harry with a score of 200. That is, Tom has twice the score, or 200 points higher, compared to Harry. Who's better off?

Tom is better off. Even though he has a significantly higher score, Tom's plaque is regressing. It is therefore quiescent with its components being extracted, inflammation subsiding, the artery is in a more relaxed state, etc.

Harry's plaque, in contrast, is active and growing: inflammatory cells are abundant and producing enzymes that degrade supportive tissue, excessive constrictive factors are constantly causing the artery to pinch partially closed, fatty materials are accumulating and triggering a cascade of abnormal responses.

This is therefore a peculiar situation in which a higher score is actually better than a lower score. It reflects the power of adhering to a preventive program. It also demonstrates how two scans are better than one because they show the rate of increase given a particular preventive approach.

Warning: Your cardiologist may be dangerous to your health!

12. September 2006 William Davis (1)

Warren had a moderately high LDL cholesterol for years and took a statin drug sporadically over the past 7 years. Finally retired from a successful real estate investment business, he had a CT heart scan to assess his heart disease status.

Warren's score: 49. At age 59, this put him in the lowest 25%, with an estimated heart attack risk of 1% per year or less--a relatively low risk. At this heart scan score, the likelihood of an abnormal stress test was less than 3%, or a 97% likelihood of a normal stress test. Most would argue that a stress test would be unproductive, given its low probability of yielding useful information. In other words, there would be a 97% probability of normal blood flow through Warren's coronary plaque, and less than 3% likelihood that a stent or bypass surgery would be necessary.

Warren was also without symptoms. He hiked and biked without any chest discomfort or breathlessness. A prevention program like Track Your Plaque to gain control over future coronary plaque growth was all that was necessary and Warren had high hopes for a life free of heart attack and major heart procedures.

Then why did he go through a heart catheterization?

Warren did indeed undergo a heart catheterization on the advice of his cardiologist. When I met Warren for another opinion, it became immediately obvious that the heart catheterization was completely unnecessary. Then why was this invasive procedure done? There can only be a few reasons:

--The cardiologist didn't truly understand the meaning of the heart scan score. "We need to do a 'real' test."

--The cardiologist was terrified of malpractice risk for underdiagnosing or undertreating any condition, no matter how mild.

--The cardiologist wanted to make more money. Talking about heart disease prevention is a money-saving, not a money-making, approach.

Regardless of which of the three motivations was at work here, they're all inexcusable. A disservice was done to this man: he had an unnecessary procedure, incurred some risk of complication in the process, and gained nothing.

An ignorant or profit-seeking cardiologist is worse than the unscrupulous car mechanic who, when presented with an unknowing car repair customer, proceeds to replace the carburetor and rebuild the engine when a simple 5-minute adjustment would have taken care of the problem.

I estimate that no more than 10% of my colleagues follow such practices, but it's often hard to know who is in that 10%. Ask pointed questions: Why is the catheterization necessary? What is the likelihood of finding information useful to my health? What are the alternatives? (By the way, the emerging CT coronary angiograms can be a useful alternative in some situations like this.)

Track Your Plaque is your source for credible information. Be well armed.

I don’t have high blood pressure!

12. September 2006 William Davis (0)

Art undeniably had high blood pressure.

At age 53, he had all the “footprints” of high blood pressure that’d been present for at least several years: abnormal patterns by EKG, abnormally thick heart muscle, and an enlarged aorta by an echocardiogram. These sorts of changes require many years to develop. Art’s blood pressure was 140/85 sitting quietly in the office.

“That’s about what my primary care doc gets, too. Whenever it’s high, he takes it again after a few minutes and it always comes down.”

Art tried to persuade me that his blood pressure was high today only because of the traffic on the way into the office. When I dismissed this as a cause, he insisted that stress he’d been suffering because of his teenage son was the cause. “I just know I don’t have high blood pressure!”

Who’s right here? Well, Art is not here to defend himself. But one fact is crystal clear: you cannot develop complications of high blood pressure unless you truly have high blood pressure!

In other words, Art’s abnormal changes in heart structure (thickened heart muscle and enlarged aorta) are serious changes that develop only with years and years of sustained blood pressure at least as high as the one in the office. His blood pressure almost certainly ranged much higher at other times, particularly during stressful situations like waiting in the check-out line at the grocery store, watching a suspenseful TV show, petty irritations at his job, and on and on.

Blood pressure does not have to be high all the time to generate complications of high blood pressure. It can be sporadic, variable, even occasional. Clearly, sustained high blood pressure is the worst situation that creates adverse consequences more quickly. But blood pressure that wavers from low to high only some of the time can still, given sufficient time, cause the very same unwanted effects.

Control of blood pressure is crucial to your coronary plaque control program. Blood pressure may be boring: not as exotic, say, as lipoproteins, and not as fun as talking about nutritional supplements. But neglect blood pressure issues and you will not gain full control over coronary plaque growth—-your heart scan score will increase.

Watch for an upcoming Special Report on the Track Your Plaque Membership website, a full detailed discussion of how to recognize when blood pressure is an important issue, along with a full discussion of nutritional methods to reduce it, often sufficient to minimize or eliminate the need for medication.

Throw away total cholesterol!

17. May 2006 William Davis (1)

Richard's total cholesterol without treatment was 186 mg/dl. "That's great!" his doctor declared, referring to the conventional dictum that total cholesterols less than 200 carry low risk. Several fingersticks in a mall kiosk set up by a local hospital to check total cholesterols confirmed Richard's low number.

But after Richard's unexpected hospitalization and two stents for severe coronary blockages, he demanded better answers.

Tragically, the answer was there all along: Despite a "favorable" total cholesterol, his HDL ("good") cholesterol was a miserable 32 mg (ideal >60 mg).

Total cholesterol is actually the sum total of HDL cholesterol, LDL cholesterol, with a contribution from triglycerides. That's why a low total cholesterol can conceal a low HDL.

This situation is quite common. And low HDL is accompanied by a constellation of other undesirable causes of heart disease, most notably small LDL.

Don't accept total cholesterol as your sole measure of risk. It's nearly worthless. If you live in Bangladesh or a third world country, well perhaps that's the best you can get. But if you live in the U.S. or developed world, it's absurd to rely on total cholesterol.

Smart Start not so smart

15. May 2006 William Davis (2)

Kellogg's has crafted a campaign to support the American Heart Association featuring acress Sela Ward. Her attractive face, familiar to many TV and movie viewers, does add a comforting face to their efforts.

What's in this cereal made by the manufacturers of Pop-Tarts, Cheez-It, Rice Krispies, and Chips Deluxe cookies?

There are, indeed, some healthy ingredients: oat bran, potassium; you can even get a version made with soy protein. But there's sugar listed as the second ingredient. High-fructose corn syrup is also listed prominently. (Remember this issue? High-fructose corn syrup causes overwhelming sugar cravings, causes your triglycerides to skyrocket, and is probably among the principal food ingredients that make you obese.)

Upon detailed questioning of my patients struggling to lose weight, this and products like it are often among the "healthy" foods they've gravitated towards. We spend a great deal of time dissuading them of this idea.

A one-cup serving of Smart Start is low in fat (1 gram) but contains 43 grams of carbohydates, of which there are 14 grams of sugar. There are a meager 3 grams of fiber. To me, this sounds like a cupcake.

The Kellogg's people are exceptionally clever marketers. Partner with the American Heart Association and movie stars? Brilliant!

You should trust food manufacturer advertising about as much as you trust drug manufacturer advertising, which is to say not at all.

Kellogg's sold $10 billion dollars of food products last year. They are the world's leading producer of breakfast cereals. They are a leading producer of convenience foods: cookies, crackers, cereal bars, and frozen waffles under the brands Keebler, Pop-Tarts, Eggo, Cheez-It, Nutri-Grain, Rice Krispies, Famous Amos, and Kashi.

Can they cash in on healthy trends? They'll certainly try.

Does anybody have a normal vitamin D level?

15. May 2006 William Davis (0)

We now routinely check everyone's vitamin D blood level at the start of the program. (The measure to obtain is 25-OH-Vitamin D3. This is not to be confused with 1,25-OH2-vitamin D3, which is a kidney function measure.)

Of the 10 people with levels drawn today, none were even close to normal levels (which we define as 50 ng/ml)--not a single one.

The majority were in the range of severe deficiency (<20 ng/ml). Only two had levels in the 30s. None had higher. (Remember: I'm talking about people in Wisconsin, a terribly sunlight-deprived area much of the year. This might not apply quite as vigorously to Florida residents or others in sun-exposed regions.)

Curiously, I've also seen several people this week who had extraordinary quantities of coronary plaque on their heart scans (scores >1000), all of whom had extremely low vitamin D levels. One of these people had fairly unimpressive lipoproteins, with very minimal abnormalities identified. (This is quite unusual, by the way.) It makes you wonder if a profound deficiency of vitamin D is sufficient to act on its own as an instigator of coronary plaque.

The more we examine the issue of vitamin D deficiency, the more fascinating it gets. I suspect we've just scratched the surface and there's a lot more to learn about this tremendously interesting nutrient. Nonetheless, with what we're seeing in our experience, I'm urging everyone to get a blood vitamin D level.

Don't believe your LDL cholesterol!

14. May 2006 William Davis (0)

Harry's case is typical. For years, his doctor told him his LDL cholesterol of 123 mg was okay. But a heart scan score of 490 (90th percentile at age 52) made him question just where his coronary plaque came from.

Lipoprotein analysis told a very different story: His LDL particle number was 2400 nmol, meaning his trueLDL was more like 240 mg, nearly double the value of LDL obtained through his doctor. Harry had other sources of risk, too, but the LDL particle number was a clear stand-out.

Why does this happen? How can LDL cholesterol be so terribly inaccurate?

LDL cholesterols obtained in virtually all labs are not measured, they're calculated. The calculation was developed in the 1960s by Dr. Friedewald at the National Institutes of Health and therefore goes by his name (the Friedewald calculation). Dr. Friedewald derived this simple calculation to permit doctors across the U.S. to obtain LDL cholesterols, which were technically difficult to measure in those days by using measured HDL, total cholesterol and triglycerides.

Doctors were told that the only time that the Friedewald calculated LDL was inaccurate was when triglycerides exceeded 400 mg. So most family practitioners and internists still believe that calculated LDL's are, for the most part, quite accurate.

Nothing could be further from the truth. When LDL's are actually meaured, you find that LDL is rarely accurate. In fact, in our experience, inaccuracy of 30-50% is the rule, sometimes 100%. The one telltale hint that calculated LDL is wrong is when HDL is <50 mg--that's nearly everybody.

So what's your LDL? You won't really know unless it's measured. Our preferred method is NMR (LipoScience) LDL particle number, probably the most accurate of all. Second best: apoprotein B, direct measured LDL, and non-HDL. (We'll cover this issue much more extensively in an upcoming report on the www.cureality.com website in an extensive Special Report.)

Are you the exception?

14. May 2006 William Davis (0)

I read about 40 heart scans this morning. In the stack was a 41-year old man with a heart scan score of 841.

That's terribly high for anyone, let alone a 41-year old person. He's lucky to find out about this before catastrophe strikes.

People like this worry me. In general, we advise men to consider a heart scan age 40 and older; women 50 and older. If there's anything exceptional about your family history or your own history, then you might notch these numbers down another 5-10 years. For instance, if your Dad had a heart attack at age 43, you might consider a scan at age 35. Or, if you've had diabetes for several years and you're a 42-year old woman, you might think about a scan. (Men tend to develop measurable plaque by heart scans 10 years before women.)

There are no hard and fast rules. It's unusual for a male to have a score >0 before age 40. Likewise, it's very uncommon for a woman to have a score >0 before age 50. But there are occasional exceptions--but they can be very important exceptions.

Our 41-year old man with the score of 841, for instance, probably had a high score since his mid-30s. I've seen several women without any obvious risk factors with scores in the several hundred range in their early 40s.

My rule: When in doubt, opt for safety. Every day, I still read about people in their 30s, 40s, and 50s dying of heart attacks. It shouldn't happen.

When in doubt, get the heart scan. The most you'll lose is the cost of the scan and a modest exposure to radiation. If your score is zero, you know you're safe for the next 5 or more years. But if you have an exceptional score at a young age, take preventive action.

Self-empowerment in health: The new wave in health care

12. May 2006 William Davis (0)

Track Your Plaque is just one facet of the broad and powerful emerging wave of self-empowerment in health.

Hospitals, drug and device manufacturers, and the medical establishment don't like this idea. People managing their own health? That's ridiculous! Dangerous! But mostly unprofitable.

Self-empowerment means having easy access to simple, safe, and inexpensive diagnostic tests like heart scans, carotid scans, bone densitometry (for osteoporosis), cholesterol tests, abdominal ultrasound, even brain scans (e.g., CT or MRI) for people with a family history of brain aneurysm.

Opponents of this idea worry about the "false-positives" that come about with broad testing, i.e, detection of abnormalities that are artifactual. Our experience is that false-positives are only an occasional problem with any test. Instead, we find that most people have many true-positives. In CT heart scanning, for example, we find many unsuspected enlarged aortas (potential future aneurysms), valve disorders, and aortic calcium. These are all important in a preventive program. Unfortunately, your doctor's definition of false-positive often means that no corrective procedure or operation is required.

Other evidence that self-empowerment in health is growing:

--The nutritional supplement movement. What better example of power in managing your own health is there than the fabulous array of nutritional supplements available?

--Medications moving to over-the-counter status. Gradually, more and more medications are trickling into availability for you to obtain without a doctor's prescription.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The rapidity and depth of information available on the Internet today is mind-boggling. It will fuel the self-empowerment movement by providing sophisticated information to the health care consumer previously available only through your physician.

--High-deductible health insurance plans. If health care consumers will bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention to minimize long-term costs.

There are more. But the movement is powerful and broad--and unstoppable. Let the establishment with vested interests in preserving the status quo fuss and complain, just like horse and buggy manufacturers did in the early 1900's when the autmobile came along.

Vitamin D deficiency is rampant

12. May 2006 William Davis (0)

Today alone I've seen several people with severe deficiencies of vitamin D.

We're now checking everyone's blood vitamin D level at the start of the program. The measure that most accurately reflects your vitamin D status is 25-OH-vitamin D3. This is very confusing to many physicians, who traditionally have thought of 1,25-di-Hydroxy vitamin D3 as the standard test to measure. What they're failing to recognize is that this second measure is a kidney product, not a reflection of vitamin D status.

Using 25-OH-vitamin D3, several people today alone had levels of <10 ng/ml, clearly in the category of severe deficiency (generally regarded as <20ng/ml).

The majority of people we see in the office are Wisconsin residents. It's no wonder they're deficient. Although it's mid-May, we've seen the sun only a handful of days this year. And most of the days have been too chilly to wear short sleeves and shorts to permit sufficient surface area for UV exposure.

Living in a sunny climate, however, is no guarantee that you have sufficient blood vitamin D levels. Two recent studies have shown that 30-50% of the residents of sunny southern Florida and Hawaii are also deficient. (Why, I'm not sure.)

Although our experience thus far is anecdotal in several hundred people, my impression is that people who have normal blood levels of vitamin D (we regard normal as 45-50 ng/ml) have a far easier time of halting or regressing coronary plaque.

Vitamin D is among the most exciting nutritional tools we've come across in a long time. The conversation is making the media, which impresses me tremendously, given the fact that nobody stands to profit financially to any significant degree through vitamin D supplementation.

For a wonderful collection of discussions on vitamin D, go to Dr. John Cannell's website, www.vitaminDcouncil.com. You'll find a huge quantity of scientific background and conversation on the whole idea. I believe you will be thoroughly impressed with just how powerful the argument in favor of vitamin D has become.

What if wheat products were illegal?

11. May 2006 William Davis (3)

Imagine if anything made of wheat were illegal: bread, bagels, crackers, pasta, pretzels, donuts, Shredded Wheat cereal, Raisin Bran, pastry, cookies, cakes, cupcakes. . . Your grocery store would then be unable to carry any of these products.

How empty would the grocery store shelves be?

There would be very little. The stores would be filled instead with vegetables and fruits, meats, and dairy products. But aisle after aisle would be empty. There'd be no cereal aisle. There'd be no snack chip aisle. The ordinarily overcrowded bread shelves wouldn't be there.

Bakery? Nope, not there either. Pasta and noodles? Empty. How about cakes and pastries? Also gone.

Getting the picture? American groceries are dominated by wheat products. What would happen to your health and the health of your family if wheat were abruptly removed from your choices? Would you be less healthy?

No. In fact, your health would be hugely improved. You'd lose a significant quantity of weight. Extraordinary numbers of people would lose diabetic or pre-diabetic tendencies. Feelings of sluggishness, sleepiness, and moodiness would dissolve. Blood pressure would be reduced. The incidence of cancer, skin disease, and inflammatory diseases would plumet.

From a plaque control perspective, your HDL cholesterol would rise, triglycerides drop. Small LDL would improve dramatically.

The message: Slash wheat products from your diet. Yes, you'll miss the smell and taste of freshly baked bread. But you'll do it for many more healthy years. And you may do it without a 14 inch scar in your chest.

The sobering tale of small LDL

10. May 2006 William Davis (0)

Every day, I learn to respect small LDL more and more.

Small LDL particles, and its evil partner, low HDL, is among the most common reasons why someone fails to fully gain control of coronary plaque and heart disease risk.

Just yesterday, I saw a slender businessman (6 feet 1 inch in height, 186 lb.) whose small pattern persisted despite niacin, fish oil, oat bran, and raw almonds. We generally think of small LDL as an overweight person's pattern, but in some people the genetics are quite powerful and it can be expressed even in slender people.

The solution: More physical activity and exercise; cut back on processed carbohydrates, particularly wheat products like breads, pasta, crackers, breakfast cereals; think about magnesium (see our two recent reports on magnesium on the www.cureality.com membership website, the latest report to be posted this week); be sure sleep is adequate (gauge this by whether you're energetic during the day and don't fall asleep watching TV or movies). Lack of sufficient physical activity in people with sedentary jobs is probably among the most common reason the small LDL pattern persists.

Ignore small LDL and it can be like a hidden cancer in your body, growing and metastasizing (not literally, of course), fueling coronary plaque growth. Be sure your doctor assesses whether you have small LDL if you hope to gain control of your coronary risk.

Burn off the fat

9. May 2006 William Davis (0)

If you've ever wondered just how many calories you're burning with various activities like yard work, driving, climbing stairs, etc. go to this great website that will calculate it for you: http://www.caloriecontrol.org/exercalc.html.

Here are some examples:

Dancing for 30 minutes(fast, e.g., tango): 193 calories
Yoga for 30 minutes: 204 calories
Washing the car for 30 minutes: 173 calories
Vacuuming for 30 minutes: 88 calories

(All are for a 170 lb person.)

As you see, physical activity does not necessarily have to consist of exercise. It doesn't require fancy equipment or expensive outfits. But it does require you to keep moving. Sedentary work is among the most common reasons I see in my patients for failing to control weight and its associated lipoprotein patterns, like low HDL and small LDL.

If your work is sedentary, then a minimum of 60 minutes of physical activity per day is necessary to begin to correct weight-related patterns. If you gauge by calories burned, then a useful goal is 500 calories per day in physical activity--at a minimum.

Do heart scans cause cancer?

14. July 2009 William Davis (3)

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

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

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

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

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

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

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

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

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

CT heart scans and radiation: The real story

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

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

Richard C. Semelka, MD

Professor and Vice Chairman, Department of Radiology

University of North Carolina–Chapel Hill

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

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

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

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

Just how much does medical radiation add to our exposure?

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

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

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

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

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

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

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

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

The media frenzy

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

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

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

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

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

Typical effective radiation dose values for common tests

Computed Tomography

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

Non-CT

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

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

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

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

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

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

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

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

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

Heart scans, CT coronary angiograms and the future

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

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

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

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

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

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

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

Goodbye, fructose

12. July 2009 William Davis (35)

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

The study is published in its entirety here.

Compared to glucose, fructose induced:

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

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

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

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

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

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

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

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

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

The statin-free life

8. July 2009 William Davis (20)

Matt came to me because his doctor couldn't reduce his LDL cholesterol.

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

We started out by characterizing his lipoprotein patterns:

--LDL 155 mg/dl

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

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

--No lipoprotein(a)

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

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

I therefore asked Matt to:

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

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

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

--HDL 52 mg/dl a 24% increase

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

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

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

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

Creatine: Not just for muscle heads

5. July 2009 William Davis (29)

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

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

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

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

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

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

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

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

Having healthy muscle mass doesn't make you bulge like a bodybuilder. With modest efforts at strength training, ain diameter and a few centimeters in length, is like a house of cards: It's bound to topple sooner or later, and the bigger it gets, the less stable it becomes.

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

Back to basics: Coronary calcium

30. January 2012 William Davis (42)

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

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

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

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

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

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

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

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

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

But it's the best we've got.

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

Myocardial infraction

15. January 2012 William Davis (45)

I've seen a few heart attacks this past year . . . but none in the people who follow this program.

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

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

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

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

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

Diet is superior to drugs

7. January 2012 William Davis (27)

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

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

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

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

Isn't that great? Spectacular job, Might!

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

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

Low-carb is heart healthy

4. January 2012 William Davis (88)

Anybody following the discussions in these pages know that: Limiting carbohydrate intake reduces risk for coronary heart disease and heart attack.

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

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

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

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

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

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

Mocha Walnut Brownies

1. January 2012 William Davis (11)

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

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

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

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

Preheat oven to 350º F.

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

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

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

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

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

Are you hungry?

6. December 2011 William Davis (43)

Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

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

The wheatless report that:

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

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

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

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

Chocolate . . . for adults only

30. November 2011 William Davis (22)

If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.

I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

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

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

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

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

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

"Friday is my bad day"

19. November 2011 William Davis (29)

At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

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

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

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

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

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

"What happens on Friday?" I asked.

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

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

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

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

HDL 80 mg/dl

14. November 2011 William Davis (73)

More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

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

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

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

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

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