Is it mainstream or alternative?

A question I get about once a week: "Is your program a kind of alternative medicine?"

Our program for control and reversal of coronary plaque using CT heart scans applies an eclectic panel of tools to achieve its goals. We use high-tech methods like lipoprotein analysis and CT heart scans; nutritional supplements like fish oil, vitamin D, and l-arginine; diet strategies and "functional foods" (using foods as a therapeutic tool); and conventional medication.

I don't consider this approach "alternative" in the sense that it uses unmeasurable or spiritual strategies. But I don't consider it mainstream, either, since current mainstream practice of heart disease prevention is far less rigorous with far less satisfactory results.

I think I can sum up the Track Your Plaque approach by saying that we use tools that work. Our measure of success is whether or not your heart scan score is stopped or reduced--that's hard to fudge. You can call it what you will, but I call it the best program for heart disease prevention I know of, alternative or mainstream.

Want to see someone turn diabetic?

If you want to witness the transformation of someone into a pre-diabetic or diabetic, put them on a low fat diet.

Dr. Dean Ornish's program, detailed in his books, Dr. Dean Ornish's Program for Reversal of Heart Disease and Eat More, Weigh Less , are woefully outdated in 2006. Yet the low fat notion continues to show up in the consciousness of people I talk to about heart disease reversal.

"I'm already on a low fat diet. Do you think my heart scan score has reversed?"

Highly unlikely. What Dr. Ornish (as a non-cardiologist, by the way) failed to recognize is that what he did manage to reverse in a small number of people is something called "endothelial dysfunction", but he did not reverse or shrink coronary plaque.

Given the limitations of technology when the Ornish concept got its start, it appeared as if reversal was obtained. In reality, all his approach accomplished was a relaxation in tone of abnormally constricted arteries, thus giving the appearance of reversal. Increased artery tone, or endothelial dysfunction, is extremely common when atherosclerotic plaque is present.

Any cardiologist will tell you that there are many ways to reverse endothelial dysfunction: exercise, weight loss, cholesterol drugs, drugs for high blood pressure, fish oil, hormonal therapy, vitamin C, l-arginine, etc. There is nothing special about a low fat diet.

In fact, Track Your Plaque followers will recognize that a low fat diet is, in fact, potentially harmful, particularly when low HDL or small LDL is part of your pattern.

Let's bury the outdated ideas of the Ornish low fat diet once and for all. It doesn't work. All it may do is confuse you and set you back from your real coronary plaque reversal program.

Inulin: A fiber for weight loss

Here's an interesting product that seems to be gaining some popularity for weight loss: Inulin.

Not to be confused with "insulin", with which it is completely unrelated, inulin is a naturally-occurring plant fiber. It's found in broccoli, asparagus, celery, etc. Like beta-glucan from oats or pectin, inulin is a so-called soluble fiber, a fiber that assumes a gel-like consistency when exposed to water.

Inulin has the effect of increasing satiety, or the sensation of fullness. This cuts your craving for foods. I've tried it recently and I prefer it over glucomannan, another soluble fiber for satiety.

The people at Stonyfield Farms have been adding inulin to their yogurts from some time. The nutritionist at the company tells me that there's 2-3 grams of inulin per 6 ounce container of their yogurt.

You can also find inulin as a supplement that you can add to foods, available from some health food stores and online supplement companies. I came across a neat product called Fiber Choice that's now being distributed widely throughout the U.S. I tried their Weight Management version. It was a delicous strawberry taste. The label says take two chewable tablets twice a day, but I found that two tablets three times a day somewhat better. It's best taken around 30-60 minutes prior to each meal and it causes you to be fuller with less food. One caution: It'll cause loads of gas, especially in the beginning. For that reason, you might try starting with a smaller dose, or start on the weekends when you have the option of some privacy!

More info on the Fiber Choice product can be found at their website, http://www.fiberchoice.com.

Disclaimer: I have no relationship with the manufacturer of this product. I'm simply passing on some thoughts on my experience with this interesting possibility for weight loss.

Will you recognize the truth when you see it?

Do you ever wonder that, if the truth were given to you, that you'd recognize it as such? Or would you dismiss it as just another bunch of nonsense?

After all, you and I live in the Information Age. It means that we have access to mountains of information like never before in human history. But it also means that the truth is often drowned out by an avalanche of mis-truths, sales pitches and marketing, and just plain nonsense.

This struck me the other day when I was talking to a patient.

64 years old with a high heart scan score placing her at significant risk, she looked confused. I'd just described the multitude of causes of coronary plaque that we'd uncovered. The heart scan alone had been a shocker.

"I don't understand. My doctor told me that I had nothing to worry about. I've known him for years and he knows me really well. He did a stress test. That was fine. I don't get all this other stuff you're telling me--lipoprotein whatever..."

Despite my efforts to help her gain an understanding of our intensive approach, she just became increasingly more frustrated. "I just don't think I can do this."

That's the last I've heard from her. As far as I know, she's returned to the comfort of her family doctor who has reassured her over the years. And perhaps there's some good in that. But I do fear for the day when, unexpectedly, she suffers some catastrophe that we told her was coming sooner or later unless real preventive efforts were started.

You could say that she failed to recognize the truth when it was given to her-- boldly, unadorned, and with far greater scientific certainty than the casual reassurances she was accustomed to. But, unfortunately, that's all that some people want.

Don't neglect the basics in your heart disease reversal program

Carl loved new ideas and novel approaches. You could tell by the sheer number of nutritional supplements he took. His list had grown to 18 different supplements over the past two years.

Carl came to me for coronary plaque regression. Lipoprotein analysis did uncover several previously unsuspected abnormalties, most notably small LDL particles and lipoprotein(a). In addition, Carl's LDL cholesterol ranged between 111 mg-156 mg and he was clearly hypertensive, with systolic blood pressures consistently around 150-160. (Recall that people with Lp(a) are more prone to hypertension.)

Carl was more than willing to have his lipoprotein(a) reduced. We did so with niacin and testosterone and the level dropped to near zero. Likewise, we corrected his small LDL pattern with niacin, fish oil, and a reduction in processed carbohydrates.

But Carl really resisted doing much about his LDL cholesterol and high blood pressure. I got the sense that these "boring" issues simply didn't interest him. After all, LDL cholesterol and blood pressure were the stuff of TV commercials and the popular conversation propagated by drug companies.

Carl's follow-up heart scan, however, finally persuaded him: a 24% increase in one year, likely due to the neglect of the basic issues.

I liken Carl's case to being like the teenager with a new car who polishes the paint to a bright finish, puts new wheels and tires on it, spruces up the interior with various doodads--but then fails to change the oil. Sometimes it's the most basic issues that can diminish your success.

Issues like LDL cholesterol and high blood pressure aren't the most glamorous, but they do count in your coronary plaque control program.

Is your doctor a hospital employee?

There's a disturbing trend that's growing--silently but rapidly.

In Milwaukee, three hospital systems compete for the local health care dollar. To gain more control over revenues and the routing of patients, the hospitals are aggressively hiring physicians to work for them. I've witnessed many of my cardiology colleagues, primary care doctors, and a substantial number of procedural specialists enticed by the offers made by hospital employers.

This phenomenon is not unique to Milwaukee but is being used in many, perhaps most, major cities in the U.S.

This means that physicians are employees of the hospital. That way, employee-physicians are obliged to use only the hospital system that employs them. In the old days, your doctor could use any hospital he/she desired, depending on the quality, location, facilities, etc. Now, many physician-employees are given no choice but to use the hospital that pays their salary.

That by itself is not necessarily bad. But combine salary with incentives for bringing in patients for hospitalization and procedures--that the rub. In other words, physician-employees are incentivized to generate more revenue for the system, just as employees in many other industries.

If you're a salesman for an insurance company, your job is to bring in more business. If you're a worker on an auto production line, you're expected to meet certain quotas. These same principles are now being applied to many physicians.

How does this affect you? Well, if your physician--especially procedure-driven specialists like cardiologists, general surgeons, orthopedists, etc.--is a hospital employee, BEWARE! Do you really need that procedure, or is your doctor suggesting you have a procedure because it will add to his track record?

Prevention? In this model of health care, why bother? It certainly doesn't pay for a hospital to keep you well. Then why should your physician-employee?

Be careful who you're dealing with. If your physician is a hospital-employee, don't bet on getting preventive care. It's more likely you're that just a future source of revenue when it's time for your bypass operation, hip replacement, carotid endarterectomy, etc.

What more powerful argument is there for increased self-empowerment and information for health care consumers?

Take a walking vacation

If you're planning a vacation, why not consider a walking vacation?

The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htm

Lengthier walks may require some advance planning and toting some supplies. Don't forget the water!

From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless.

There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.

Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking!

"Expanded indications for implantable defibrillators"

So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.

It goes on to say: "In January 2005, indications for implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."

Ka-ching!!! Hear the money piling up in the bank?

The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation.

Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack.

Get a heart scan--but then don't delay taking action!

I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week.

Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period.

Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet.

This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future.

Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow.

What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.

The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan.

Feel that nudge in your back?

You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business.

Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"

In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."

Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them.

Are endogenous nutritional supplements better?

Just a muse.

Endogenous substances are those that are already contained within our bodies. They are part of basic human equipment.

Exogenous substances are those that come from outside of our bodies. This includes various substances in foods, drugs (most, though not all), and pesticides.


I often mull over all of the tools we use in the Track Your Plaque program to achieve control over this thing called coronary plaque. It struck me that just about all the supplements we use that seem to provide outsized benefits are all endogenous substances themselves:

--Omega-3 fatty acids from fish oil
--Vitamin D
--l-arginine
--Niacin (vitamin B3)

Many of the other substances, though not directly relevant to our plaque-control efforts, but are among the most effective nutritional supplements, also supplement endogenous levels: calcium pyruvate, creatine, acetylcarnitine, DHEA, testosterone, progesterone, growth hormone, pregnenolone, phenylalanine, tyrosine, melatonin, etc.

Curiously, most drugs are not meant to directly supplement endogenous levels, but are designed either to enhance or block an enzyme (e.g., acetylcholinesterase inhibitors that block breakdown of acetylcholine; HMG CoA reductase inhibitors to block cholesterol synthesis; angiotensin converting enzyme inhibitors to reduce blood pressure), to exert toxic effects on an organism (antibiotics, antivirals), or to exert an entirely unique effect that does not ordinarily occur in the human body (some anti-cancer drugs, for instance). (This is an admitted, vast over-simplification.)

That's not to say that any endogenous substance is desirable or safe when supplemented. Cortisol, thyroid hormone, and estrogens are three examples of endogenous substances that have downsides when administered at slightly more than physiologic concentrations.

Nonetheless, it makes me wonder if the world of endogenous substance supplementation has not been fully explored. Are there other endogenous substances that are as potent and wonderful, for instance, as vitamin D but not yet fully appreciated? I'm sure there are.

Vitamin D Newsletter reprinted

Reprinted here is the unfailingly informative Vitamin D Newsletter from Dr. John Cannell. Although there's little here specifically about heart disease, there's so much great information about vitamin D that I thought most would still appreciate it.



The Vitamin D Newsletter

May, 2008

Yesterday's Washington Post article, Too-Good-To-Be-True Nutrient?, sums up the April 9th vitamin D symposium at UCSD in San Diego, which was nothing short of spectacular. Carole Baggerly outdid herself organizing it and explaining how she got involved. Make no mistake; Carole is both serious and energetic. She told about her efforts to introduce resolutions at upcoming meetings of various professional groups. Then she introduced the volunteers from the San Diego Black Nurses Association who made sure the conference went off without a hitch. Then Carole introduced the four speakers. The slides of each speaker are available at Grassroots Health.

Before I tell you the highlights of the conference, I'd like to tell you about another conference, this one in Germany, this May 17th and 18th. It is the Third International Symposium on Vitamin D Analogs in Cancer Prevention and Therapy. Readers know how I feel about giving analogs to vitamin D deficient patients instead of vitamin D but speakers include Michael Holick, Reinhold Veith, Bill Grant, Tai Chen, Heidi Cross, David Feldman, and Roger Bouillon, all of whom know the importance of the nutrient. Most of this conference is for scientists, not lay people. However, Michael Holick is the first speaker and if you have not heard his latest talk about vitamin D, it might be worth a trip to Germany.

The first San Diego speaker was Dr. William Grant. Since leaving NASA to begin a full-time career as a vitamin D researcher, Bill has published dozens of studies and has another dozen in the works. Using ecological studies (from Greek oikos, house + German -logie, study or studying your own house) of UVB irradiance and cancer, Bill reported that 15 cancers (colon, esophageal, gallbladder, gastric, pancreatic, rectal, small intestinal, bladder, kidney, prostate, breast, endometrial, ovarian, Hodgkin's lymphoma, and non-Hodgkin's lymphoma) are associated with lower UVB light. He concluded that 257,000 cancer deaths in 2007 in the USA were accounted for by inadequate vitamin D levels. Of course the problem with ecological studies is that it easy to be vitamin D deficient in Miami, all you have to do is listen to your doctor's advice and stay out of the sun. Recently, a group from the Arizona Cancer Center found almost 80% of Arizonians had levels below 30 ng/ml. So much for sunny spots.

Jacobs ET, et al. Vitamin D insufficiency in southern Arizona. Am J Clin Nutr. 2008 Mar;87(3):608-13.


The next speaker was Professor Cedric Garland. I found myself wondering how he did it. I became convinced that vitamin D prevents cancer five years ago. Cedric and his brother Frank and his colleague Ed Gorham knew it 30 years ago! I know what it is like to tell someone that vitamin D prevents cancer and see them think, "Here we go again, another miracle vitamin." I know what it is like to try and explain and watch people die unnecessarily. But I've only had that experience for five years. Cedric has dealt with that frustration for thirty years. Almost thirty years ago, Cedric and Frank Garland published evidence that vitamin D prevents cancer. In fact, it was Cedric's first publication. Thankfully, the paper was recently recognized as being so important that it was republished in 2006 by the International Journal of Epidemiology. You can read the entire paper for free by clicking on the second link below and then clicking on "free final text", courtesy of Oxford Journals.

Garland CF, Garland FC. Do sunlight and vitamin D reduce the likelihood of colon cancer? Int J Epidemiol. 2006 Apr;35(2):217-20.


Cedric began by showing the incidence of type-1 diabetes and multiple sclerosis by latitude. I had no idea that the latitudinal data was so strong for type 1 diabetes in children. This disease is almost nonexistent around the equator. Type-1 diabetes is but one of the three modern childhood epidemics caused by the sunlight-hating dermatologists, the other two, I think, are autism and asthma. Next he showed latitude and 25(OH)D levels, which reminded me to be suspicious of high levels, unless they use accurate methods of detecting 25(OH)D. Some methods used, even in this country, are over detecting vitamin D and telling patients their levels are above 50 ng/ml when they are, in reality, much lower. Cedric's data showed Thailand had mean levels of 70 ng/ml, which I doubt and suspect were due to inaccurate 25(OH)D tests. He then reviewed evidence of the 25(OH)D levels needed to prevent numerous cancers. The safest levels are somewhere above 50 ng/ml. Cedric spent most of his time presenting an entirely new theory of carcinogenesis, one dependent on vitamin D maintaining cellular junctions. I suspect this paper will also be reprinted in 20 years. The only disagreement I have is with his recommendation for cancer patients to start at fairly low doses. For reasons I recently explained, the risk benefit analysis indicates cancer patients should take 5,000 to 10,000 IU per day and they may have no time to lose. Why worry about the phantom of vitamin D toxicity if you may be dying of cancer? Just have your calcium checked along with frequent 25(OH)D levels. Get your levels up to 70-90 ng/ml if you have cancer.



Does vitamin D treat cancer?

The next speaker was Professor Bruce Hollis. He reviewed basic physiology of vitamin D and emphasized that the entire system is designed to deal with an excess not with an insufficiency of vitamin D. Numerous mechanisms are available in your body to prevent vitamin D toxicity but few are available to deal with insufficiency. Then he briefly mentioned one of the most important discoveries about vitamin D in the last few years, one where Professor Neil Binkley of the University of Wisconsin was senior author. (In the last four years, Professor Binkley has become a prolific vitamin D expert and I hope Carol Baggerly is able to get him to speak at some of the upcoming conferences she hopes to sponsor.) As I have pointed out before, Hollis and Binkley's crucial discovery was that the body doesn't start storing the parent compound, cholecalciferol, until 25(OH)D levels reach about 50 ng/ml. They showed, using basic steroid pharmacology, that 50 ng/ml should be considered the lower limit of adequate 25(OH)D levels.

Hollis BW, Wagner CL, Drezner MK, Binkley NC. Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-4.


Bruce kept the audience enthralled with a review of all the disease states that indicate 25(OH)D levels need to be much higher than they are now, that is, the multiple biomarkers that suggest the lower limit of 25(OH)D levels should be above 40 ng/ml and closer to 50 ng/ml. Then Professor Hollis spoke of his ongoing study in pregnant women and how he got approval to use 4,000 IU of vitamin D per day back in 2003, quite an accomplishment. He also reviewed another one of his research projects, one that answered an age old question, why is breast milk a poor source of vitamin D? How were prehistoric infants supposed to get their vitamin D, by lying out in the sun where saber tooth tigers would eat them? No, they were hidden in caves and had to have another source or the human race would have died out long ago because rickets destroys a woman's and infant's chance to live through childbirth due to rachitic deformations of the mother's pelvis. Carol Wagner and Bruce Hollis, together with their colleagues, answered that age old question, human breast milk is a poor vitamin D source because virtually all modern mothers are vitamin D deficient. That is, when pregnant women keep their levels where we think prehistoric human levels were, about 50 ng/ml, breast milk becomes a rich source of vitamin D. First Carol and Bruce gave 2,000 IU per day, then 4,000 IU per day and finally 6400 IU of D3 per day to lactating women. Only at 6400 of D3/day did the women maintain both their own 25(OH)D levels and the levels of their breast feeding babies above 50 ng/ml. On 6400 IU/day, the vitamin D activity of the breast milk went from about 80 to 800 IU/L. Quite a discovery, and another reason for all of us to keep our levels above 50 ng/ml.

Professor Robert Heaney went last, discussing 74 slides. So much of what we know about vitamin D today is due to Robert's unceasing dedication to vitamin D, the most recent example being his and Joanne Lappe's randomized controlled trial showing that increasing baseline levels from 29 to 38 ng/ml reduced the risk of getting cancer by around 70%. He again pointed out that the body does not begin to consistently store much vitamin D until your levels get to around 50 ng/ml. He also went through multiple biomarkers of vitamin D. That is, what level or intakes do you have to have to reduce the incidence of multiple diseases? He covered calcium absorption, osteoporosis, risk of falling, muscle function, death and disability of the aged, TB, influenza, cardiovascular disease, hypertension, diabetes, cancer, multiple sclerosis, and gum disease. How can one vitamin be involved in so many diseases? Simple said Dr. Heaney, "vitamin D is the key that unlocks the DNA library." He then reviewed toxicity and concluded there is no evidence that it occurs at levels below 200 ng/ml or with intakes (total) below 30,000 IU per day. Of course, we have no reason to think anyone needs 30,000 IU per day or levels of 200 ng/ml, which would be irresponsible. But someone with a serious cancer should consider getting their level up to 70-90 ng/ml and that may take 10,000 IU per day or even more in some people. As a rule of thumb, 1,000 IU will raise 25(OH)D levels by about 10 ng/ml.

Then Professor Heaney addressed a public health question. How much would we have to give all Americans to get 98% of people above 32 ng/ml without causing toxicity in anybody? The answer: 2,000 IU per day. Of course 32 ng/ml is not adequate but it would be a great first step. Furthermore, of the people left out, a high percentage would be African Americans. In fact, Dr. Talwar recently reported that 40% of African American women fail to achieve a level of 30 ng/ml even after taking 2,000 IU/day for a year.

Talwar SA, Aloia JF, Pollack S, Yeh JK. Dose response to vitamin D supplementation among postmenopausal African American women. Am J Clin Nutr. 2007 Dec;86(6):1657-62.


He also discussed his recent study giving healthy adults 100,000 IU as a single dose. If you start with a baseline level of 28 ng/ml and take 100,000 IU as a single dose, mean levels will remain above 32 ng/ml for two months. If you rely on such stoss doses, but you start with a lower level, or want your levels above 50 ng/ml, how often do you need to take 100,000 IU? We don't know the answer to the last question but we know that Grey et al gave 50,000 IU per week for four weeks then 50,000 per month for a year to 21 patients with hyperparathyroidism. Blood levels rose from a mean of 11 ng/ml at baseline to 30 ng/ml at one year and levels did not continue to rise after six months. Remember, that means half the patients had levels lower than 30 ng/ml at the end of the year. Also remember that the metabolic clearance (how quickly you use it up) might be higher in certain disease states.

Grey A, et al. Vitamin D repletion in patients with primary hyperparathyroidism and coexistent vitamin D insufficiency. J Clin Endocrinol Metab. 2005 Apr;90(4):2122-6.


That last point, metabolic clearance, is only one of a number of reasons that patients vary in their response to vitamin D. Remember, a surprising number of patients will tell their physician they are taking vitamin D when they are not, some will be taking preparations that have less in it than the label says, some will not absorb it, and some people weigh more than others. As Dr. Heaney points out, even if you know patients took 100,000 IU, great variably exists in individual response. At the end of two months some will have shown a minimal response and other much more. This is a field where little is known. Do different disease states use up vitamin D quickly? The answer is probably yes. Furthermore, variability also exists in how one metabolizes and catabolizes (breaks down) vitamin D. Also, what is the interactive effect of drugs that use the same liver enzymes for catabolism? We just don't know and that is why vitamin D blood testing is crucial. Remember, the only test to have is a 25-hydroxy-vitamin D. Do not let anyone get a 1,25-dihydroxy-vitamin D; it will not tell you if you are vitamin D deficient and is usually only indicated in evaluating high blood calcium.

As far as 25(OH)D levels go, many of you have written complaining about the high cost of a 25(OH)D levels at some labs. I've got some good news. For the next month, Life Extension Foundation is having a sale on their 25(OH)D blood tests, only $32.25, including the fee for drawing the blood. (No, we don't get funding from Life Extension, I wish we did.) Life Extension uses LabCorp, which, in turn, uses an accurate method to determine 25(OH)D levels, the DiaSorin Laiason method. The only problem is that DiaSorin, LabCorp, and Life Extension all say that 30 ng/ml is acceptable. It is not. Take enough vitamin D or get enough UVB radiation to get your levels above 50 ng/ml. To order the test, call Life Extension at 800 208-3444. Unfortunately, this offer is not available in New York, New Jersey or Rhode Island.

Also, Dr. James Dowd has written a fine book about vitamin D, The Vitamin D Cure. Get this, he is board certified in internal medicine, adult rheumatology, and pediatric rheumatology, an associate professor at Michigan State University, and runs his own Arthritis Institute and the Michigan Arthritis Research Center. He gives a formula for how much vitamin D you need but stresses the importance of testing to know for sure. He uses the formula of 2000 IU for every 100 pounds of body weight, which is as accurate an estimation as one can make without knowing baseline levels. Of course it depends on so many things, as Dr. Dowd points out, such as percentage body fat, latitude, skin type, sun exposure and age. He gives case after case examples of how vitamin D not just prevents disease, but seems to have a treatment effect. He also stresses three other things I've written about before, acid base balance, magnesium and potassium. If you can't get eat enough fruits and green leafy vegetables to obtain your potassium and magnesium and to get rid of low-grade chronic metabolic acidosis, then you should consider magnesium supplements and potassium bicarbonate supplements.

With these four experts and with this month's vitamin D news articles about breast cancer, brain function, artery blockage in the legs, soft skulls in babies, peripheral neuropathy in diabetics, childhood type-1 diabetes, colon cancer, and stress fractures and with the increasing number of scientists around the world jumping on the vitamin D express, why doesn't the government do something? What will it take? Like Carole says it will take a grassroots effort.

The first thing to do is tell your family and friends about vitamin D. Tell your doctor. Get your family's 25(OH)D tested, including your children. Once people begin to see it works, they will get their family and friends to take it. They will feel better and then the word will spread. All the government can do is make vitamin D illegal or limit the amount in each pill. The first is unlikely but not the second. With 5,000 IU capsules widely available, many people give no thought to taking one a day. But if the government limits the sale of anything over 400 IU and people had to take 12 of the 400 IU tablets, instead of one of the 5,000 IU, they might balk at so many pills. Before our officials in Washington take such a step, let's hope they read the Washington Post.

Biggest bang for your nutritional buck

Judging by the conversations here, in the Track Your Plaque Forums, and elsewhere, it's clear that many people are searching for the perfect diet.

Should we reconsider the role of saturated fat? Are there fractions of fatty acids in saturated fat that are more or less harmful? How about the role of fats on cancer risk? How about the role of proteins like casein on cancer risk? Are there flavonoid sources, or combinations of flavonoids, that yield outsized health benefits? Is there a ceiling for omega-3 fatty acid supplementation? Is there a role for linolenic acid sources in cardiovascular disease prevention? And on and on.

All important issues, to be sure, ones that we've all zig-zagged through over the past 30 years.

I also see patients every day, however, who are not interested in micro-managing their diet. Their goals are less ambitious: lose 20 lbs, feel good, raise HDL, reduce triglycerides and small LDL, all while meeting all the other responsibilities in their lives, like children, spouses, maintaining a household and jobs.

So, if your interest is not to consider whether we should distinguish myristic acid sources from palmitic, or if epigallocatechin is better when combined with quercetin, then the biggest bang from your nutritional buck can come from one single strategy:

Eliminate wheat flour products

Secondarily, avoiding corn starch products and "goodies" (candy, fruit juices, fruit drinks, cookies, potato chips, etc.--you know what they are) is important, as well.

It means weighing your diet more heavily in favor of vegetables and fruits; lean meats; healthy oils; and raw nuts and seeds, all in unlimited quantities. Dairy products should be limited, however, because of sugar effects.

Of course, this advice clearly contradicts the pronouncements of the USDA Food Pyramid (6-8 servings of grains per day), the American Heart Association, and the diabetes-causing American Diabetes Association diabetic diets.

But, follow this approach, a diet strategy that appears too simple to be effective, and the majority of people lose dramatic amounts of weight, raise HDL, reduce triglycerides, reduce small LDL, reduce C-reactive protein and other inflammatory measures, reduce blood pressure, and raise self-esteem.

It's also a lot easier than it sounds (after habits are broken) because the appetite stimulating effect of wheat is removed. Many, if not most, people also experience increased energy, including elimination of the afternoon "slump," improved sleep, less mood swings, less intestinal problems.

It may not be perfect, but if your interest is to get the most with a modest amount of effort, it works like a charm for the majority of people.

Can skinny be fat?

You're going to hate this.

Dr. Romero-Corral and colleagues from the Mayo Clinic presented an analysis of the National Institutes of Health-funded National Health and Nutrition Examination Survey (NHANES-3) at the recent American College of Cardiology meetings. (Science Daily also has some coverage on this report.)

Their analysis identified 2127 adults from the NHANES database who had normal body-mass indexes (BMI) between 18.5 and 24.9 units), average age 41 years old. When broken down by percent body fat (measured with bioimpedance, meaning a small electrical current is passed through the body, much like what the store-bought Tanita devices do), with normal-weight obesity defined as >20% body fat in males, >30% body fat in females, 55% of participants met criteria for designation as normal-weight obesity.

Compared to people with similar BMI's but who fell below these body fat percentage cut-offs, the normal-weight obese men had increased ratios of Apo B to Apo A1; were much more likely to have increased blood sugars or be diabetic; have higher C-reactive protein (CRP); were several-fold more likely to meet other criteria for diagnosis of metabolic syndrome; had lower HDL cholesterols; and had higher blood pressure. Women with normal-weight obesity were four-fold more likely to have coronary disease.

While preliminary, this suggests that a substantial number of people with apparently favorable body weights and BMIs are, in actuality, overweight when judged by metabolic parameters. This then probably leads to increased risk for heart disease. We can then fairly readily extrapolate the argument that a reduction in weight to even lower BMIs likely reduces or corrects these patterns.

This argument is similar to that proposed by several others, arguing that BMI is a flawed measure, since it does not incorporate muscle mass or skeletal factors ("big- or small-boned"). Instead, they have argued that waist circumference is preferable.

The normal-weight obesity syndrome was originally identified by Dr. Antonio de Lorenzo and colleagues at the University of Tor Vergata, Rome, Italy, and reported in Normal weight obese (NWO) women: an evaluation of a candidate new syndrome. Their studies of women with this "syndrome" have suggested that heightened measures of inflammation are present despite apparently normal body weight and BMIs. One such report, Normal-weight obese syndrome: early inflammation?, is available in full-text.

Is there a lesson to be learned for the Track Your Plaque program? I believe there is. I believe it means that, if you have any weight-sensitive parameter, such as low HDL, small LDL, high triglycerides, high CRP, high blood sugar, high blood pressure, etc., then further weight loss might be considered, even if BMI is around 25. Obviously, there is a rational limit to how far you can push this concept. (Anorexia is not good for you either.)

I find this a useful concept. It provides yet another potential strategy to pursue when the above patterns are encountered. Perhaps it's also a way to cap reliance on niacin, whose effects closely mimic that of weight loss.

Now that's a lot more preferable to more and more statin drug, isn't it?

Fatal underdose

Since vitamin D has been the topic of a fair amount of media coverage, I've received many questions about this fascinating "nutrient." A day doesn't go by without several nurses, friends, even fellow physicians stopping me to ask about vitamin D.

When I inform them that the average dose for females in this region (upper Midwest) is 4000-5000 units per day, 5000-6000 units per day for males, they are all surprised. "Then why did they say just take your multivitamin every day, or just drink your milk on the news?"

Many people are even more surprised, sometimes completely turned off, when they hear that, to be truly confident of adequate vitamin D dosing, a blood level of 25(OH) vitamin D3 needs to be checked. Now we're talking real hassle!

But there is no other way to do it. In order to obtain the full potential benefits of vitamin D, such as reduction in blood sugar and sensitization to insulin, reduction in cancer risk (especially prostate, colon, and breast), reductions in blood pressure, increased bone density, not to mention markedly increasing the likelihood of stopping or reducing your heart scan score, then achieving a desirable blood level of 25(OH) vitamin D is necessary.

Checking a blood level of vitamin D is no more difficult than having a cholesterol test, unless, of course, your doctor balks at the idea. (Time for a new doctor if that occurs.)

All too often, someone will be convinced they are taking a sufficient dose of vitamin D of, say 2000 units per day, only to discover that their blood level of 25(OH) vitamin D is something like 17 ng/ml--severe deficiency, sufficient to leave them exposed to all the undesirable consequences of vitamin D deficiency. Even though 2000 units per day represents 500% of the Institute of Medicine's recommended Adequate Intake for adults, to those familiar with the Track Your Plaque program it likely sounds like a child's dose.

Many variables enter into the equation in your body that determines your need for vitamin D: body size (heavier or larger people need more, with obese people often requiring enormous doses); sex (men need more than women); age (aging results in dramatic loss of ability to activate vitamin D in the skin); race; skin color (darker skinned people require more). Trying to guess your need is a fool's game. It's also a game that can seriously compromise your health and your hopes of ever stopping or reducing your heart scan score.



The message is clear: You cannot guess what your vitamin D need is. You cannot properly judge your vitamin D requirement by your age, body size, sex, or any other characteristic. Having a tan or a lack of a tan is a lousy indicator, as well. A simple blood level of 25(OH) vitamin D is an absolute necessity to gauge your vitamin D status, both before starting and while on your supplement.

Is direct-to-consumer drug marketing a failure?

According to the poll just completed by 80 participants on The Heart Scan Blog, 50% of respondents said they were less likely to take a drug after viewing an advertisement for it. A whopping 3 (4%) said that they would be more likely to take the drug after viewing an advertisement.

I find that interesting. If half the people responding are less likely to become customers of a drug company, then how does the drug industry justify running around-the-clock, every-few-minute ads? Spending by the drug industry for direct-to-consumer (DTC) advertising has ballooned over the past few years, and is now well over $30 billion dollars per year.

Unfortunately, despite the views of the highly-educated, curious, think-for-yourself, health information-seeking sorts of people who read this blog, drug companies still come out on top by DTC advertising. Estimates vary, with a 2006 U.S. Government Accountability Office study reporting that, for every $1 DTC advertising, sales are increased by $2.20. A 2000 Harvard study showed a higher return of $4.40 for every advertising dollar spent.

I'm sure the drug companies themselves have a very tight accounting handle on their own set of figures. We may not be terribly fond of these people and their often suspect tactics, but they're not stupid. They are certainly not stupid when it comes to making money.

Interestingly, 80% of the funds spent on DTC advertising focus on the 20 or so most popular drugs, all of which are used for treatment of chronic conditions like high cholesterol and high blood pressure, markets that are large and long-term. It pays very little to advertise drugs that may serve small markets for a short period. The implicit message is that this is not at all about informing the public. It is about advertising to grow revenues and profits--pure and simple.

It makes me wonder what the results of our poll would have been had we conducted it in 2000 before many people hadn't yet been brought to the brink of vomiting from the endless onslaught of commercial after commercial, complete with smarmy spokespeople (a la Lipitor's Dr. Robert Jarvik). What will it show in two years? Will the broader public join the more informed people who read this blog and become increasingly inured to the hard sell tactics?

For further discussion of this topic, click here for a reprint of an August, 2007 New England Journal of Medicine study, A Decade of Direct-to-Consumer Advertising of Prescription Drugs provides background, along with commentary on the impact of DTC drug marketing since the FDA allowed it 10 years ago. (Because it is a study and not an editorial, the editors fall short of making any recommendations for improvement or calling for a moratorium.)

Cheerios and heart health



Anna responded to the Heart Scan Blog post, Can you say "sugar"? with the following wonderfully telling comment:

A measured bowl of Cheerios and a bit of milk (whole, because it's what I had), equal to 75 grams of carbohydrate, gave me the highest ever blood glucose reading from a food (not counting glucose solution from a Glucose Tolerance Test). I was attempting a "homemade" version of a 3 hr GTT before going to my doctor with my concerns about my BG.

My BG started to rise very fast within 15 minutes after eating the cereal, peaked at about 250 mg/dL at 45 minutes, then slowly dropped. By about 60-75 minutes, I experienced strong hunger and carb cravings as the BG began to slowly drop, and by about 2.5 hours after eating, my BG had suddenly dropped quite low (in the low 70s) and I had developed a nasty hypoglycemic feeling (shaky, irritable, craving sugary foods, headache, etc.).

It's hard for me to see "heart healthy" Cheerios (or any other highly processed breakfast cereal) as anything other than a bowl of pre-digested sugar that contributes to roller coaster blood glucose and insulin levels, which a great way to start anyone's day. Certainly, I don't do well with Cheerios because I clearly have a damaged glucose regulatory system (probably a diminished or absent first phase insulin response, but I can't imagine that it is doing any good for people with healthy glucose regulation, either.

I banned prepared cold cereals from our house. If my 9 yr old son gets cereal at all at home, it's whole groats (not even rolled or steel cut because those aren't truly "whole grain" anymore), soaked overnight in some water and a tsp of plain yogurt (soaking neutralizes phytates and reduces cooking time), then cooked about 8-10 minutes (water added as necessary). Sometimes I add a bit of quinoa or almond meal prior to soaking to boost the protein content a bit. I garnish with a pat of butter, some heavy cream, and a dusting of cinnamon. If I'm feeling *really* indulgent, I drizzle about 1 tsp of Grade B maple syrup on top (Grade B is stronger in flavor and so less can be used). I don't eat this cereal myself, and truthfully, I'd rather my son not, either, but he sometimes wants cereal. It's the least damaging compromise I can come up with that we can both live with.



I have also seen diabetic effects from Cheerios: rises in blood sugar, exagerration of small LDL, drops in HDL, rises in triglycerides. Yes, it may reduce LDL a small quantity, but so what?

The Cheerios "heart healthy" claim is based on a piece of research apparently performed by Dr. Donald Hunninghake at the University of Minnesota and reported in 1998:

A study conducted at the University of Minnesota Heart Disease Prevention Clinic and published as "Cholesterol-Lowering Benefits of a Whole Grain Oat Ready-to-Eat Cereal" in the May issue of the Nutrition in Clinical Care journal in 1998, showed that people can lower their blood cholesterol by an average of 3.8% over six weeks by enjoying 3 cups of cold cereal made with 100% whole grain oats everyday as part of the meals and snacks in a healthy lower-fat diet.

(Unfortunately, I could not locate the actual publication. It doesn't mean it doesn't exist; I just couldn't locate it. Perhaps it's in a small journal not entered into the online publication database.)

The purported effects of Cheerios should not be confused with that of actual, intact oat bran, as suggested by studies such as those of Brenda Davy et al, High-fiber oat cereal compared with wheat cereal consumption favorably alters LDL-cholesterol subclass and particle numbers in middle-aged and older men, in which significant reductions in LDL particle number and small LDL (NMR) were obtained. (This study was also supported by Quaker Oats.) Several studies have shown that oat bran does indeed reduce LDL cholesterol, sometimes as much as 30-50 mg/dl. Cheerios can not even come close to this.

If Cheerios were nothing more than finely pulverized oats, then perhaps it wouldn't be so bad. But add corn starch and sugar, and you have ingredients that have potential to distort LDL particle size and yield blood sugar-escalating effects like those described by Anna.

The gravity of perpetuating these myths is brought home by a testimonial posted on the website for Cheerios:

“I had unexpected open heart surgery a year ago. As I adopted heart health habits during my recovery, I realized that I should have been eating the Cheerios cereal I carried around in a plastic baggie so many years for my kids!”

The IF Life: Intermittent fasting

There's a wonderful blog called The IF Life: Intermittent Fasting and Instant Freedom. It is written by personal trainer (and apparently former corporate bigshot), Mike O'Donnell.

Mike has a great take on brief, intermittent fasting that I found helpful and I believe you will also.






Intermitent Fasting 101: How to Start, Part I

The biggest question people have is how to effectively use IF (intermittent fasting) to achieve their goals and maximum results. These results and goals can vary by each person with fat loss, muscle gain, better health, improved performance in your sport of choice and more. With that comes the individuality of what is a person’s insulin resistance, current body composition (bodyfat%), daily lifestyle, eating habits, macronutrient ratios (carbs/protein/fat), type of exercise program, frequency and volume of training, recovery demands, and so forth. You are unlikely to find 2 people with the same set of parameters and same exact responses to an IF protocol. What does this mean? Well just that we need to start with a basic IF program, and then learn how to monitor results and adjust as we go. Even down the road things will change as you will improve health, lower insulin resistance and maybe change performance and recovery needs. So nothing is ever just one set way. Life is dynamic (always changing and evolving) and so should be the way we see our own journey for health and fitness.

What is IF?

For those that may not be familiar to the term, intermittent fasting is just taking times of fast (no food) and working them into your lifestyle. This can be either daily or a couple times a week (will get into that more below). Benefits include improving insulin resistance (which you will hear alot about as being the #1 key marker in so many health factors including weight loss, muscle gain, performance, recovery, anti-ageing and disease prevention) and giving the body a chance to do some internal cleaning (or housework), which can lead to improved immune function and overall health. If you want to see studies of all the benefits of IF/CR, please the resources page.


How do I begin to IF?

Is there only one set way in which to do IF? No. I could easily come up with 10 different IF protocols based on 10 people’s individual’s needs, lifestyle, exercise, goal, macronutrient ratios, and so forth. We will keep it simple and give the 2 most frequent and basic options.

Daily Fasting: Typically done every day and only giving the person a smaller eating window in which to get their calories. (for example, a 18hr daily fast would mean someone would only eat every day between the hours of Noon and 6pm). You will see varying times from 15-19 hours for daily fasting.
Fasting 1-3x a week: This could also be called alternate day fasting/calorie restriction (for those doing it every other day). This is just fasting of usually longer periods 18-24 hours but only 1-3x a week. Many variations to play with here.
“But which one is better and how to I do it now if I want…….”. Whoa, slow down. I know many have questions but let’s still try to keep this simple for now and expand into more specifics later. So far many people have experimented with both types of IF and have seen great results. But you also have to take into account all the other variables such as what is the person eating in that window? Is is junk food? Is it low carb? How many times a week are they doing it? Are they overweight and wanting just fat loss? Are they lower bodyfat but looking for improved performance and health? How many times a week are they exercising? What kind are they doing and what intensity? The list can go on and on, but let’s start to analyze the 2 types of IF and let you decide which one best suits your lifestyle.

Daily Fasting (15-19 hours):

The Advantages are:

--simple eating strategies for every day
--even people that may not eat 100% clean foods can see weight loss due to the smaller window and lower calorie total per day


The Disadvantages are:

--Can possibly lower metabolism if calories are too low for too long (not what you want if your #1 goal is weight loss)
--Not getting enough food in the smaller window may also lead to muscle loss for more active people (not good)
Fasting 1-3x a week:


The advantages are:

--Allows a person to make sure they are getting enough calories on the non-fasting days, and then just keeps to a simple small feed window (if any) on the IF days.
--Simple thinking for people who do not have experience in how to eat clean to eat one day, and then eat in a smaller window the following day (alternate day fasting/CR). This can achieve fat loss for people who are mostly overweight and may not be too active. (of course don’t get me wrong, that eating healthy is our main goal but this can be a good step for some people to start their weight loss jounrey and learn how to make better choices as they go)


Disadvantages:

--Doesn’t force a person to make better choices with their food (as one could probably eat junk one day, and then fast the next and still lose weight). Not something we want long term because this is not going to improve your other health markers (diseases prevention, insulin resistance) like a good IF program on healthy foods.


Again I can’t say it enough, as there are so many variables to play with in an IF program. Some people may say “well it didn’t work for me” or “I didn’t gain any muscle”. Well unless I know everything about what you do for exercise daily, your total calories, when you eat and your macronutrient ratios (protein/carbs/fats), I can’t even begin to help. IF is a simple tool to start with, but you have to take full responsibility for your own health and progress and learn when it is not working and when to change things up! Like I said, if it is NOT working then stop IF and rethink your attack plan (or get a professional to coach you on it).

So to sum up, here are some examples of what you can play with:

Daily Fasting of 15-19 hours. I would highly suggest that if you do this make sure you are recovering from your exercise and start only Mon-Fri and give yourself the weekends to eat all day (hopefully with healthy choices of course)


Fast 1-2x a week to start if you have never done any fasting or do not know how to eat healthy and control your macronutrients. Start with 1-2 days a week with fasts of 18-20 hours (I wouldn’t start with 24 hr fasts to begin as most people can not handle the hunger cravings and in turn will just end up eating all the wrong foods when they do eat) and say eat only from say 1pm-6pm for example. Drink lots of water (add lemon, your liver will appreciate it! and it will help with the hunger). For example, fast Wed and Sun (or whatever days fit into your schedule)

Or you can do a mixed approach and fast every other day for a small eating window. For example eat all day Mon, only 12-6pm on Tues, all day Wed, 12-6pm on Thurs, etc. Start with bigger eating windows and make them smaller as you get used to fasting. This approach may work for people who have alot of weight to lose and can not (I should really say “will not” as everything is a choice!) eat 100% healthy for the moment. This approach may not work for more advanced people who have a high activity level unless you are getting a ton of health calories in that fasting window.
“So What Do I Eat on the Fasting Days?”

That’s the best part, you should be able to eat unlimited healthy foods (healthy proteins, fats, veggies, fruit, nuts…see Paleo Diet in the resources page). If you are eating more processed foods, breads and other high calorie intakes then you may have to monitor and control portions. Please know this is NOT about chronic calorie restriction or starving yourself. When I do weeks of eating 1-7pm, I am eating a ton of protein and veggies (complex carbs pwo also). I am hardly starving myself. I am not taking in 4000 cal a day however, so my daily average of say 2200-2500 cal is still low compared to the alternative. If you want to lose weight of course you will need a calorie deficit to pull the “stored energy” out of fat cells. That is the advantage to eating “Paleo”, you can’t over eat on protein, healthy fats, fruits (in moderation) and veggies. If you are making bad choices or starving yourself on IF, you may lose the effectiveness or slow progress. All goes back to the fact that if it is not working, then change something up! (there is always something that can be changed…and food choices is the #1 place to start!) I don’t count calories, and by eating natural foods that have been around for 100s of years….I don’t need to! (eating healthy natural foods will not only help you lose weight but also improve your health and lower your risks of diseases….so eating for health should always be the #1 goal in any program)

Hopefully this will give a good overview while trying to keep it simple. Remember it’s your journey to take, measure progress and adjust things that are not working. Start with one approach, and modify it. Who knows, your approach may change every couple months and that is ok. Life is always changing and so should your approach to health and fitness (as the body always responds better to change than sticking with the same eating/exercise approach for a long period of time).

Warfarin is scary stuff

Gilbert is a 58-year old high school science teacher.

When I first met Gil, he'd been having bouts of atrial fibrillation and had required various medications to suppress recurrences of the rhythm. However, because his rhythm proved somewhat difficult to control, his electrophysiologist (heart rhythm specialist) prescribed warfarin to reduce the risk of stroke. With atrial fibrillation, because of blood stagnation (in the left atrial appendage) in the heart, there is a stroke risk of approximately 8% per year. Warfarin reduces this risk substantially, to about 2%.

I met Gil because he had a cholesterol disorder. In my practice, the first step in gauging the implications of a lipid or lipoprotein disorder is to obtain a heart scan. If the heart scan score is zero, great. It means that we have plenty of time to treat the disorder since risk for cardiovascular events is near zero also; it means less intensive efforts less intensive efforts are necessary. But if the heart scan score is, say, 1200, then an aggressive approach in short order is required, since the risk for heart attack may as high as 20-25% per year, even in the absence of symptoms.

Gil's heart scan score: 787--high and posing a risk for heart attack of about 5-10% per year without preventive efforts. Gil did indeed prove to have a complex lipoprotein disorder, as well as high blood pressure, vitamin D deficiency, and several other potential contributors to coronary plaque.

Gil did just about everything right: He exercised, followed the recommended diet, achieved better than the Track Your Plaque 60-60-60, lost 18 lbs of abdominal fat.

Gil's rhythm stabilized for several months, only to have atrial fibrillation break through again. So Gil's electrophysiologist re-prescribed warfarin.

18 months later, Gil's 2nd heart scan score: 1410--a near doubling. Unsettling to Gil and to us, to say the least.

How can this happen in the face of perfect lipids/lipoproteins, correction of hidden causes like lipoprotein(a) and inflammation, along with a vigorous lifestyle effort?

I fear that the culprit might be warfarin.

Warfarin, better known by its brand name, Coumadin, may have some effects that intersect with the Track Your Plaque mission of reducing coronary plaque.

It is no secret that, beyond the obvious risk of bleeding from blood thinning, warfarin also may:

--Accelerate aortic valve calcification
--Accelerate calcification of the framework of the mitral valve (the mitral "anulus")
--Accelerate osteoporosis
--Induce an artificial situation of vitamins K1 and K2 deficiency.

The vitamin K1 deficiency is the route by which blood thinning is achieved. However, the K2 deficiency may have undesirable consequences, among which are the above list of various pathologic calcifications.

I therefore wonder if warfarin dramatically accelerated the coronary calcium that we track to gauge the progression of coronary atherosclerosis. One experience is hardly sufficient reason to sound the alarm. It is also difficult to pinpoint the cause of the explosive growth in Gil's coronary calcium specifically on warfarin.

That all said, I am quite certain it was the warfarin.

Unfortunately, some people are unavoidably committed to warfarin, such as those with specific genetic blood clotting disorders, prosthetic valves, prior deep vein thromboses and pulmonary emboli, etc.--serious reasons. Until an alternative emerges, warfarin remains a necessity for some people. (No, nattokinase is NOT an alternative, at least not one that would permit survival.)

My personal policy is that warfarin be used only when absolutely necessary and the gains markedly outweight the risks--including that of possible accelerated calcification of multiple sites.

Whether we will be able to get Gil off warfarin and potentially gain control over his coronary disease/plaque/calcium remains to be seen. I sure hope so.

With a heart scan score of 1222, Leslie could be in deep trouble in short order.

At 64 years old, Leslie had gained nearly 40 lbs since she'd given up a lot of her activities caring for a husband who'd developed psychological difficulties and stopped contributing to the household duties. A tall woman at 5 ft 9 inches, she held her 202 lbs well, but her lipoprotein patterns were a disaster:

--LDL particle number 2482 nmol/l--an equivalent LDL cholesterol of 248 mg/dl (drop the last digit)
--HDL 38 mg/dl
--Triglycerides 241 mg/dl
--90% of LDL particles were small
--Lipoprotein(a) 240 nmol/l

Blood sugar was in the pre-diabetic range at 112 mg/dl, C-reactive protein was high at 3.0 mg/l, blood pressure was somewhat high at 140/84.

Now, with the exception of lipoprotein(a), these patterns are exquisitely weight-sensitive. A reduction in weight would yield effects superior to any medication I could give her.

Processed wheat products were a big problem for Leslie: whole wheat bread, pretzels for snacks, whole wheat pasta. Yes, they sound healthy, even endorsed by the American Heart Association, often bearing "heart healthy" labels on the packages. Don't you believe it.

In particular, Leslie had the number one cause for heart disease in America: small LDL particles, a pattern that is magnified 30-70% by wheat products. Endorsed by the Heart Association? (As I often tell people, if you want heart disease, follow the diet advocated by the American Heart Association.)

Leslie was skeptical, worried that she would be hungry all the time and would have virtually nothing left to eat. Instead, when she returned to the office three months later, she reported that eating was easy, finding healthy foods not containing wheat was easier than she thought, she felt great, finding more energy than she'd had in years.

She'd also shed 30 lbs.

Leslie's lipoprotein patterns also reflected the weight loss. She achieved her 60:60:60 Track Your Plaque lipid targets, small LDL shrunk dramatically, blood sugar and blood pressure were back in normal ranges.

I see results like Leslie's several times every week. For those of us with patterns like Leslie's, or just obesity that accumulates in the abdomen, going wheat-free is among the most powerful single strategies I know of.

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, pancakes, waffles, breading on chicken, rolls, bagels, cakes, breakfast cereal. I find elimination of wheat easier than just cutting back. I believe this is because wheat is powerfully addictive. It's very similar to telling an alcoholic that a drink now and then is okay--it just doesn't work. They need to be alcohol-free. Most of us need to be wheat-free, not just cut back.

You won't be hungry if you replace the lost calories with plenty of 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, fish, and eggs.

The majority of people who go wheat-free lose weight, sometimes dramatically. Most people also feel better: more energy, more alert, better sleep, less mood swings. 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.

Even without weight loss, going wheat-free usually raises HDL, reduces the dreaded small LDL dramtically. It also reduces triglycerides, blood sugar, C-reactive protein, blood pressure. Blood sugar control in diabetics is far easier, with less fluctuations and sharp rises in blood sugar.

Success at this also yields great advantage for your heart scan score control and reversal efforts.

Collective wisdom


As public consciousness and knowledge about health issues grows, thanks to the internet and other media, I predict that:

1) Hospitals will recede into a role of acute and catastrophic care ONLY, dropping the charade of providing health, which they do NOT.

2) Doctors and other health professionals will begin to see themselves as providers of acute and catastrophic care, also. They will stop providing day to day care, such as treating high blood pressure, cholesterol, breast exams, and other preventive maintenance.

3) Instead, preventive care will be self-provided. The public will have acquired sufficient savvy and know-how to manage issues like blood pressure themselves. They will need the assistance of helpful information resources, web-based for the most part. Much preventive care can, in fact, be algorithm-driven, just like following a simple recipe.

All the worries about runaway health care costs will be much reduced, since excessive testing driven by liability worries will disappear, repeated office visits for day-to-day issues will go away. Yes, you will need a doctor and hospital for a broken leg, car accident, unexpected cancer, or non-compliance or neglect of prevention.

But osteoporosis, high blood pressure, nutrition, weight loss, hormone management, cholesterol issues, minor complaints will all be managed by people themselves with the assistance of web-based knowledge systems.

I already sense this sort of phenomeonon developing, though in its infancy, in venues like the Track Your Plaque Forum and other health portals, places where the information being discussed exceeds the quality of information you can obtain from your doctor. Over and over again, for instance, the sophistication and knowledge demonstrated by our Track Your Plaque Forum discussions shows that the public is capable of far more understanding of health issues than many previously believed. Most of our members could carry on a credible conversation with trained lipid experts. The knowledge base of our members exceeds that of 98% of most of my colleagues when it comes to heart scans, lipoproteins, and nutrition.

I am in awe of Wikipedia, the popular online encyclopedia. Five 20- and 30-somethings have created a knowledge base that has now eclipsed Encyclopedia Britannica in size and scope, with equivalent accuracy, and relatively little cost. I'd like to see the same phenomenon occur in health care information, helping to usurp the current paternalistic "I'll tell you what to do" model.

Success--Slow but sure

John is a gentleman.

At age 76, he continues to teach at a local college. He's a delight to talk to, having written several scholarly books on religious topics. He's a fountain of knowledge on religious history and the roots of faith.

John is one of those incurably optimistic people, always greeting me with a smile and a warm handshake. I can't help but linger for a hour or so to talk with John, unfortunately disrupting my office schedule miserably.

John is another Track Your Plaque success story. Though he didn't set any records in reduction of his heart scan score, he did it simply by adhering to the program over a period of two years, succeeding slowly but surely.

John's first heart scan score: 1190, a score that carries as much as a 25% annual risk for heart attack. Among the list of causes was an LDL cholesterol in the 170 mg/dl range, along with an LDL particle number that verified the accuracy of LDL.

Among John's suggested treatments was a statin drug, since I was not confident he could reduce LDL with diet and nutritional modifications sufficiently to safely reduce both LDL and his risk for heart attack. But he proved terribly intolerant to any dose of any statin, with incapacitating and strange side-effects, like head-to-toe itching, abdominal cramps and diarrhea. It was clear: John needed to do the program without benefit of a statin drug.

I therefore asked John to maximize all efforts that reduce LDL, 70% of which were small LDL paricles despite his very slender build. He used oat bran and ground flaxseed daily, raw nuts, a soy protein smoothie every morning, and eliminated wheat and other high-glycemic index foods (including the Oreos he loved to snack on). Because the mis-adventures with statin drugs wasted nearly a year, I asked John to undergo another heart scan. Score 2: 1383, a 16% increase.

I asked John to keep on going. Thankfully, he did manage to tolerate fish oil, niacin (though it required over a year just to get to a 1000 mg per day dose), and vitamin D. With all these efforts, he did reduce LDL to the 80-90 mg/dl range. Of course, John's unflagging optimism was crucial. He did express his occasional anxiety over his heart scan score, but dealt with it in a logical, philosophical way. He understood that there was no role for prophylactic stents or bypass, and he accepted that much of his program rested on his ability to adhere to the strategies we advised.

Another year later, a 3rd heart scan: 1210, a 12% reduction.

I'm very proud of John and his success. When you think about it, he succeeded in conquering heart disease with some very simple tools, minus statin drugs. It can be done, but requires consistency and patience--and an optimistic outlook.

Vitamin D and octagenarians

Roger practically bounced in his chair vibrating with energy.

"It must be the vitamin D! I haven't felt like this in years. I can work around the yard all day and still have energy left over."

At age 84, Roger started out with pretty good health, despite a prosthetic valve and bypass surgery 5 years earlier. He looked 74, perhaps younger.

I've seen this effect now in about 20 octagenarians. A Track Your Plaque Member mentioned this same effect in his father-in-law in a discussion in our Forum. Most are taking around 6000-8000 units per day (gelcap, of course). The average dose of vitamin D tends to be higher in this age group, since by age 80, you've essentially lost the capacity to convert 7-hydrocholesterol to active vitamin D3 in the skin. Most octagenarians start with 25-OH-vitamin D3 levels of 10 ng/ml or less--profound deficiency.

I believe the effect is real, having now witnessed it multiple times. Unfortunately, my observations are too informal to qualify as a study. (I wouldn't even know how to quantify this. I suppose some sort of muscle and coordination testing might yield quantifiable measures.) However, there are some data emerging that show less fractures, falls, improved coordination, and perhaps improved memory and mentation with vitamin D supplementation, though doses often used in studies tend to be lower than what we are using in practice.

I haven't been so excited about the effects of a nutritional supplement in a long time. Vitamin D continues to yield surprises every day in its array of positive and powerful effects.

Could we say that vitamin D restores youthfulness?
