Dan had the usual collection of metabolic syndrome lipoprotein abnormalities:

low HDL of 28 mg/dl, triglycerides 280 mg/dl, 90% of his LDL particles were small.

Along with elimination of wheat and junk foods, exercise, and fish oil, I asked Dan to add niacin. I usually ask people to buy SloNiacin and begin at 500 mg per day with dinner, increased to 1000 mg per day at dinner after 4 weeks.

Dan came back several months later. His lab results:

HDL 40 mg/dl, triglycerides 76 mg/dl.

(We didn't repeat the full lipoprotein analysis, so no small LDL value was available.) Better, though still some room for improvement. I urged Dan to stick to his program, lose some more weight off his 260 lb frame, exercise, be strict about the wheat products.

Dan returned another few months later. Lab results:

HDL 29 mg/dl, triglycerides 130 mg/dl.

Dan had lost another 8 lbs and was reasonably compliant with his diet.

What's going on here? Why would he backtrack on HDL and triglycerides despite sticking to his program?

I asked Dan where he purchased his niacin. "I got it from Sam's Club. The pharmacist said to try this 'no-flush' kind so the hot flush wouldn't bother me."

Aha! It's no wonder. "No-flush" niacin, or inositol hexaniacinate, is an outright scam. It has virtually no effect on lipids or lipoproteins in humans. It's therefore no surprise that, by replacing real niacin with the no-flush variety, Dan's blood patterns began to revert back to their original state.

Let me be straight on this: No-flush niacin is a scam. It does not work: it does not raise HDL, reduce triglycerides, nor reduce small LDL. It's expensive, too, far more expensive than the real thing. It has no business being sold by stores like Sam's Club or your health food store.

SloNiacin (Upsher Smith) has become our preferred preparation. (I obtain no compensation of any sort for saying so.) We buy it at Walgreen's.

We've been engaging in a conversation on the Track Your Plaque Forum on whether niacin raises blood sugar.

Yes, it does. In the vast majority of instances, however, the rise is trivial and without consequence. Typically, someone will start with a borderline elevated blood sugar of, say, 108 mg/dl. Niacin, 1000 mg per day, then raises blood sugar to 112 mg/dl. This small increase does not oblige any specific action, nor does it pose any excess risk.

Blood sugars in the normal range of <100 mg/dl tend not to show this effect. Higher blood sugars, e.g., 130 mg/dl, may show a more exagerrated effect but it is also rarely of great consequence. People who take medications for adult type II diabetes, or people with childhood-onset, type I diabetes will also experience rises in blood sugar. This is a somewhat larger issue in these people.

Niacin is best undertaken with a change in diet, specifically a reduction in processed carbohydrate foods, particularly evil and ubiquitous wheat products.This will often compensate for the blood sugar effect.

Niacin also shares many of the benefits of weight loss: rise in HDL, drop in triglycerides and small LDL.

Keep it all in perspective: If HDL is low, e.g., 30 mg/dl, or there is a significant small LDL pattern, or you have Lp(a), using niacin--vitamin B3--is quite safe and the most effective treatment we have. It's also a vitamin. Also recall the famous HATS Trial of simvastatin and niacin: simvastatin (Zocor) reduced heart attack risk 30%; adding niacin reduced heart attack risk an astounding 90%.

Very few strategies can yield the enormous benefits, both as a stand-alone treatment or in combination with others, that niacin can, whether or not blood sugar creeps up a few milligrams.

I am continually impressed at how few of my colleagues take advantage of a wonderful nutritional supplement, Coenzyme Q10 (CoQ10).

Despite some of the recent backlash against statin agents, I do believe that they serve a role. I take issue with the pharmaceutical industry's endless advertising and force-feeding of drugs to the public and to physicians. Nonetheless, statin agents do serve a purpose.

If you go to your doctor with a fever of 103 degrees, coughing up thick yellow sputum, and you are struggling to breathe, would you refuse an antibiotic for pneumonia? Probably not. But an antibiotic for a sore throat may be a different matter.

So it goes with the statin drugs, too. An otherwise healthy 50-year-old woman with an LDL cholesterol of 140 mg/dl probably does not need a statin drug. A 35-year-old man with heterozygous hypercholesterolemia with an LDL cholesterol of 280 mg/dl, who will develop his first heart attack within the next 2 or 3 years, does need these drugs. The rub, of course, is deciding who in between also needs them.

Let's just accept that some people do indeed need a statin drug for one reason or another. How common are the muscle aches?

In my experience, muscle aches are inevitable. The longer you take a statin drug, the more likely you will develop them. The higher the dose, the more likely.

Thankfully, for most people muscle aches are more of a nuisance than a real danger. Usually, a reduced dose of the drug, periodic breaks from the drug (we often advise one or two weeks off every three months), or a change to another agent helps.

However, in my view, coenzyme Q10 provides a virtual antidote to most of the muscle aches and weakness. A recent review was published in the Journal of the American College of Cardiologist that concluded that there was insufficient evidence to support the use of CoQ10 for this purpose. Obviously, the authors do not use CoQ10 in everyday practice. If they did, they would have no doubt whatsoever that CoQ10 provides the majority of people with complete relief of the muscle complaints.

Time and time again, I have witnessed complete relief from muscle aches and muscle weakness from statin drugs using CoQ10. However, in our experience, a dose of at least 100 mg per day needs to be maintained. Occasionally, a higher dose will be necessary, e.g., 300 mg per day. The preparation also must--MUST--be an oil-based gelcap to work (just like vitamin D). The capsules that contain powder are so poorly absorbed that they usually fail to yield the needed effects.

Pictured is the Sam's Club (Members' Mark brand) that has served us well, providing reliable effects at a reasonable price. (CoQ10 is expensive, no matter where you buy it. That's the only drawback I'm aware of.) GNC has a great preparation, as does Life Extension. Just be sure it is a gelcap, not a capsule filled with powder.

There's more to CoQ10 than relief of statin muscle aches. More about that in future.

I can't help but quote a few more passages from Andy Kessler's irreverent but nonetheless insightful book, The End of Medicine. I find his quotes irresistible because I believe that he is (unintentionally) describing precisely what we are doing in the Track Your Plaque program:

"Maybe the jig is up on the cholesterol conspiracy. Any real scientist running studies on cholesterol drugs would not just check to see if participants in the study had a heart attack. You would scan, check for plaque, provide drugs, scan again, see if the plaque increased or decreased, repeat. Instead, we have a multibillion-dollar statin business based on vagaries and deception."

Kessler cuts to the chase on that one. Except we do it with a lot of things beyond drugs.

"256-slice scanners, faster than your heartbeat, just might be the magic pill of diagnosis. It's as if doctors will be saying I was blind before i could see. . . Six blind doctors feeling around an elephant and describing a wall, spear, snake, tree, fan and a rope. Looking for clues in all the wrong places. Measuring cholesterol and blood pressure is like reading the outside temperature and humidity from inside your house and guessing if it's raining. Open the window, stick your goddamn hand outside and know for sure.

How much do these scans have to cost to become widespread? $500? $100? $20? It almost doesn't matter. The savings come over time. Spread the R&D over millions and you get scale. It works.

. . . what if the spending was on detection instead of intervention? With some breakthrough, the economic consequences can be staggering. if medicine as we know it is replaced by health monitoring, hmmmm . . ."

Get beyond his humor and you see that Kessler shares our appreciation of the futility of cholesterol testing for predicting your heart's future. He advocates early detection, no surprise.

And lastly:

"I go to conferences about wikis and Wi-Fis, podcasts and blogs, and I always leave with an empty feeling, bored to tears. It's all great stuff, but technology somehow seems gripped with incrementalism. It's all really neat and cool and wow, but somehow predictable. Gee, in five years we'll have cheap terabyte drives so that we can, what, watch Simpsons reruns and shop more efficiently?

Forget that. It's all about taking control. One by one, industries are being democratized. Power is shifting from producers and service providers to users. . . Power to the people--everywhere except medicine . . . With the right tools, we'll all take control."

Amen. He's right. Taking control of health care out of the hands of the doctors and putting it in your own hands. But you are going to need better tools, more information, and guidance.

I couldn't have said it any better.

"It's not about staying young--it's about staying healthy. They say 60 is the new 50. If you stay healthy, got a good ticker lay off tobacco, are lucky enough to avoid some weird cancer, you can kick up your heels, keep running your company, or better yet, travel the world, hike a mountain, ski Zermatt--heck, Tony Randall even started a new family.

But that's a big if. We pump ourselves with cholesterol-lowering drugs as if that was the magic elixir. Not so simple.

Instead, our skin is getting peeled back for a quick look inside. This is the end of medicine as we know it. Don't guess that I might have hardening of the arteries. Open me up and take a look. Don't guess that I don't have cancer because I'm not spitting up blood or growing a tumor the size of a grapefruit out my side."

If you can get beyond some of the frat-boy joking in the book, you will see that the author, Andy Kessler, actually acquires some pretty canny insights into the future of medicine in his book, The End of Medicine.

It's a book not about the end of medicine, but about the end of medicine as we know it today: the doctor by the bedside, the treating-when-symptoms-appear approach that characterizes current practice.

Instead, Kessler predicts that new technology will supplant the role of doctor-as-gatekeeper and decision-maker. Early detection is key. He picked up on that right away, as his quote above shows.

Despite the sophomoric humor, I was impressed that much of the Track Your Plaque approach--online, self-empowered, based on the concept of early detection followed by practical and effective tools for correction, involving your doctor only peripherally--is what Kessler is trying to articulate.

In actuality, I would not necessarily recommend his book, unless you need a light moment and some fodder for thinking about our health future. But he does have some startling insights for a guy who just invests money and has no real health background.

Another excerpt:

CT Anxiety

I always feel a certain anxiety when I walk into the Hyatt Regency at the bottom of California Avenue in San Francisco. The cutsie Trolley car outside, the Embarcadero tile pattern on the sidewalk — they are all part of the package. But as I've done every time I've been there, I head straight into the lobby, tilt my head back and scan the Escher-like floors, starting at the top and then down and outwards to the bottom until I start feeling dizzy. I thank Mel Brooks for this.

This guy was zooming through someone's brain like it was a Sunday drive. More like a Sunday afternoon video game.

With my head spinning from this "High Anxiety" flashback, I stroll into the conference, half expecting to be given a barium enema by a cross between Nurse Diesel from Mel Brooks' flick and Nurse Ratched from One Flew Over The Cuckoo's Nest. I really gotta switch to decaf on days like this.

The 7th International Multi-Detector Row Computed Tomography Symposium sounded innocuous enough. I assumed it would be a bunch of technical papers on the future of scanning, where I would read the paper in the darkened hall until lunchtime and then head off for some hot Hunan and home.

Instead, the place was like a carnival for cardiologists.

Kessler has, in Silicon Valley style, left a wide wake of electronic content to get a better view of his ideas. There is a podcast located on the InstaPundit site that you can listen to at: http://podcasts.instapundit.com/AndyKessler.mp3, that provides some more of this irreverent but out-of-the-box thinker's thoughts.

For anyone looking for a discussion about the emerging role of vitamin D as a cause for coronary disease, see my recent article, Vitamin D’s Crucial Role in Cardiovascular Protection, in Life Extension Magazine, now posted online at:

http://www.lef.org/magazine/mag2007/sep2007_report_vitamind_01.htm.

Vitamin D has assumed an absolutely critical role in the Track Your Plaque program for coronary plaque reversal and dropping CT heart scan scores. Since adding vitamin D and aiming for blood levels of 50-60 ng/ml, our success rate has skyrocketed. In fact, I wonder just how well our two most recent record holders--51% and 63% drops in heart scan scores--would have fared without it. (They probably would have dropped, but no where near as much.)

Also, a full-length booklet that contains just about everything you want to know about vitamin D (or at least a right-this-moment summary of what is known about it) will be available to Track Your Plaque Members for free before the end of the year.

If you haven't done so already, DO THE D!!

Brian Wansink, author of Mindless Eating: Why we eat more than we think (see yesterday's Heart Scan Blog post), also has a Blog. Despite the bland advice offered on much of the Prevention Magazine and website, Wansink's Food Think Blog is a winner.

In a recent post, Wansink quotes a report from Science Daily that described a study he recently published in the Journal of Consumer Research. Wansink's study describes how just applying the label "healthy" to fast food choices increased consumers' calorie intake:

"When we see a fast-food restaurant like Subway advertising its low-calorie sandwiches, we think, 'It's OK: I can eat a sandwich there and then have a high-calorie dessert,' when, in fact, some Subway sandwiches contain more calories than a Big Mac."

In one study, Chandon and Wansink had consumers guess how many calories are in sandwiches from two restaurants. They estimated that sandwiches contain 35% fewer calories when they come from restaurants claiming to be healthy than when they are from restaurants not making this claim.

The result of this calorie underestimation? Consumers then chose beverages, side dishes, and desserts containing up to 131% more calories when the main course was positioned as "healthy" compared to when it was not--even though, in the study, the "healthy" main course already contained 50% more calories than the "unhealthy" one.

"These studies help explain why the success of fast-food restaurants serving lower-calorie foods has not led to the expected reduction in total calorie intake and in obesity rates," the authors write.

Interesting. In fact, I've had many patients say that they eat at Subway or similar chains and choose the "healthy" options. "That's got to be better than a cheeseburger and fries!" Perhaps not. (Of course, you can't leave Subway or other fast food operation feasting on wheat products.)

Wansink can be counted on for some truly fascinating observations into many behaviors that are subconscious but explain at least part of the reason why we're so fat. Though his Blog has a relatively short history of posts, there's lots of great commentary.

Pierre Chandon and Brian Wansink. "The Biasing Health Halos of Fast Food Restaurant Health Claims: Lower Calorie Estimates and Higher Side-Dish Consumption Intentions" Journal of Consumer Research, October 2007.

"Everyone--every single one of us--eats how much we eat largely because of what's around us. We overeat not because of hunger but because of family and friends, packages and plates, names and numbers, labels and lights, colors and candles, shapes and smells, distractions and distances, cupboards and containers. This list is almost as endless as it's invisible.

Invisible?

Most of us are blissfully unaware of what influences how much we eat . . . We all think we're too smart to be tricked by packages, lighting, or plates. We might acknowledge that others could be tricked, but not us. That is what makes mindless eating so dangerous. We are almost never aware that it is happening to us."

So opens Brian Wansink's book, Mindless Eating: Why we eat more than we think.

Wansink studies consumer behavior at Cornell University. He's the guy who scrutinizes in excruciating detail why we eat what we do, what factors determine what we eat like food color and smell, the company we keep, product packaging. He works without food industry funding, though there are plenty of researchers who do this sort of research funded by the likes of Kraft, Nabisco, and Kellogg's.

His book is packed full of the conclusions he and his team have come to over the years studying our buying and eating habits. While this information could (and is) be easily used by the food industry to coerce us to eat more and more, understanding many of the concepts Wansink talks about can also open your eyes to their clever tactics.

He especially details how our internal satiety signals fail us when external cues are present that easily trip us up. He talks about one experiment he ran in which soup bowls were rigged with concealed rubber tubes in the bottom that continually replenished the soup as the person consumed it. Thus, with the bowl continually refilled, the eater had no idea how much he or she had consumed. When the quantity of soup eaten from the endless bowl was compared to people eating from standard bowls, there was as much as a three-fold increase in the quantity and calories eaten.

Just be aware that, while Wansink is an expert in consumer eating behavior, he is not necessarily an expert in nutrition. Just as a card shark can show you lots of clever tricks to hoodwink your opponent, he might not be the best person to teach you how to play bridge.

For a great hint at some of the interesting and all-too-human observations Wansink makes, the online Prevention Magazine posted a brief video:

http://link.brightcove.com/services/link/bcpid1155399889/bclid1171884988/bctid1113465050

We might not be able to stop Big Food from selling garbage foods, but we can at least be armed with insight into how we are subconsciously coerced into eating more.

Read the story online at http://www.courant.com/news/health/hc-luckydoc.artsep10,0,7572510.story?coll=hc_features_promo

I personally hate these stories, the ones that turn heart scans into drama by describing how someone had a heart scan, then turned out to have so much coronary plaque that they had to have bypass surgery.

But I point this one out because the story is related in an interesting way. It highlights the utter ignorance that operates in heart disease detection.

The story highlights how a 50-year-old, 5 ft 8, 150 lb slender, exercising neurologist underwent a CT coronary angiogram in a newly installed device in a Hartford, Connecticut hospital (not a heart scan) that detected entirely unsuspected severe and diffuse coronary disease. You know the rest: abnormal stress test, heart catheterization, bypass surgery of the hapless doctor-now-patient, followed by grateful patient saying things like "This machine saved my life."

It probably is true. You've seen these stories before. I've witnessed these sorts of headline-makers for the past decade. I remain surprised that it still happens.

The doctor is not some ignorant, uninformed man who can't even fill out his income tax forms. Yet how does a man like this walk around with life-threatening disease and not know it? Why does it still make headlines?

Anyway, despite all my jawing about heart scans and early heart disease detection, many physicians and the public remain in the stone age of heart disease. Even though this neurologist's story made headlines, the many other people who 1) identified their heart disease earlier with a simple heart scan, then 2) took action to put a stop to it, do not make headlines. But that's the way to go.

Why isn't the rest of the story being told? Why was this man's heart disease uncovered only in its late phases? Hartford, Connecticut is not some backwater. I've been there. It's a major city with large hospitals and a University Medical Center. But a professional with presumed knowledge of health and his doctor(s) allowed this to happen?

In other words, this is not a story of success, but of failure--failure to identify coronary disease years earlier when preventive action would have prevented bypass. But that's not such a compelling headline, is it?

As an aside, I'll bet you that this man has lipoprotein(a), a severe small LDL pattern, and severe deficiency of vitamin D. Correct these and it's unlikely he'll need bypass again. But that's kind of boring, isn't it?

I'd forgotten what a powerful report Peter Jennings and ABC News produced about the enormous deception perpetrated by the food industry and its effects on health until Dr. Joe Mercola posted the YouTube clips from the report on Mercola.com.

(This is not meant to be an endorsement of everything Dr. Mercola has to say. He says lots of things; I agree with only a fraction of it. But this is a gem.)

Although made in 2004, the report remains every bit as relevant today as it was then. It concerns me deeply that, despite reports like this being broadcast to Americans, the obesity epidemic continues unabated. In fact, it's worse just in the short three years since then.

Be aware of what the food industry is up to. They intensively market high profit margin foods to us--and especially our children--to increase sales. As Jennings points out, the U.S. government (USDA) is, for a variety of reasons both good and bad, complicit with this massive deception. While many media reports continue to focus on lack of exercise as the root cause for the obesity epidemic, it is really the active and purposeful selling of processed junk foods to Americans that is principally to blame.

By the way, how many of these foods proudly boast the American Heart Association Check Mark of approval?

There's a $22 billion industry based on treating LDL cholesterol, a fictitious number.

LDL cholesterol is calculated from the following equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

So when your doctor tells you that your LDL cholesterol is X, 99% of the time it has been calculated. This is based on the empiric calculation developed by Dr. Friedwald in the 1960s. Back then, it was a reasonable solution, just like bacon and eggs was a reasonable breakfast and a '62 Rambler was a reasonable automobile.

One of the problems with Dr. Friedewald's calculation is that the lower HDL cholesterol, the less accurate LDL cholesterol becomes. If it were just a few points, so what? But what if it were commonly 50 to 100 mg/dl inaccurate? In other words, your doctor tells you that your LDL is 120 mg/dl, but the real number is somewhere between 170 and 220 mg/dl. Does this happen?

You bet it does. In my experience, it is an everyday event. In fact, I'm actually surprised when the Friedewald calculated LDL closely approximates true LDL--it's the exception.

Dr. Friedewald would likely have explained that, when applied to a large population of, say, 10,000 people, calculated LDL is a good representation of true LDL. However, just like saying that the average weight for an American woman is 176 lbs (that's true, by the way), does that mean if you weigh 125 lbs that you are "off" by 41 lbs? No, but it shows how you cannot apply the statistical observations made in large populations to a single individual.

The lower HDL goes, the more inaccurate LDL becomes. This would be acceptable if most HDLs still permitted reasonable estimation of LDL--but it does not. LDL begins to become significantly inaccurate with HDL below 60 mg/dl.

How to get around this antiquated formula? In order of most accurate to least accurate:

--LDL particle number (NMR)--the most accurate by far.

--Apoprotein B--available in most laboratories.

--"Direct" LDL

--Non-HDL--i.e., the calculation of total cholesterol minus HDL. But it's still a calculated with built-in flaws.

--LDL by Friedewald calculation.

My personal view: you need to get an NMR if you want to know what your LDL truly is. A month of Lipitor costs around $80-120. A basic NMR costs less than $90. It's a relative bargain.

Faye was clearly frustrated.

At age 52, she was having chest pains every day. A CT heart scan showed a score of zero. A CT coronary angiogram showed no plaque whatsoever.

"Everything went downhill when my menopause started. I gained weight, I started to have chest pains, my blood pressure went up, my cholesterol shot up."

She saw three physicians, none of whom shed much light on the situation. They ran through the predictable sequence of (horse, not human) estrogens, anti-depressants, suggestions for psychological counseling.

But we checked Faye for lipoprotein(a), which she proved to have at a high level of 182 nmol/l. This explained a lot.

A curious and predictable set of phenomenon occur to females with Lp(a) proceeding through the menopause. As estrogen recedes:

--Lp(a) levels rise dramatically.

--Blood pressure goes up, sometimes creating severe hypertension by mid- to late-50s.

--Chest pain can develop, presumably due to "endothelial dysfunction" or "microvascular angina", both representing abnormal coronary artery constriction facilitated by worsening expression of Lp(a).

All too often, these phenomena get dismissed as simply part of the menopausal package, when they are, in fact, important facets of this very important genetic pattern that confers high risk for heart disease.

If any of this rings familiar for you or a loved one, think Lp(a). Though Faye hadn't yet developed any measurable coronary plaque by her CT heart scan score, it was likely on its way, given the surge in Lp(a) expression as menopause unfolded--unless its recognized and appropriate preventive action taken.

I've talked about this before, but I need to periodically remind everybody:
Vitamin D must be an oil-based capsule, a gel-cap, not a tablet.

Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago.

However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day.

She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.)

In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations.

You may have to look, but if you want to enjoy the extraordinary benefits of vitamin D replacement, it must be an oil-based capsule. Carlson's and Vitamin Shoppe have excellent prepartions. They raise blood levels substantially and consistently, and they're inexpensive. We pay $5.99 for a bottle of 120 capsules.

What if vitamin D cost $200 rather than $2?

In other words, what if cholecalciferol, or vitamin D3, was a patent-protectable agent that would sell for an extravagant price, just like a drug?

Vitamin D would be the hot topic. There would be TV ads run during Oprah, slick magazine two-page spreads with experts touting its outsized benefits, insurance companies would battle over how much your copay should be.

The manufacturer would host large fancy symposia to educate physicians on how wonderful vitamin D is for treatment of numerous conditions, complete with dinner, a show, and gifts. They would hire expert speakers to speak, scientists to have articles ghost-written, give out knick knacks with the brand label inscribed--just like Lipitor, Actos, Vytorin, ReoPro, Plavix . . .

After all, what other "drug" substantially increases bone density (up to 20% in adult females), enhances insulin responses 30% (equivalent to the TZD drugs, Actos and Avandia), and slashes colon cancer risk?

But it's not a drug. That is both vitamin D's strength and its weakness. It's a strong point because it's natural, phenomenally helpful across a variety of conditions, and inexpensive. It is also a weakness because, at $2 a month, no one is raking in the $12 billion annually that Pfizer makes for Lipitor that allows it to fund an enormous marketing campaign.

Vitamin D is a "discovery" of huge importance for health, including making reductions of CT heart scan scores far more likely for more people. And it comes without a prescription.

Fanatic Cook has posted an excellent summary on the recent negative attention cast on garlic preparations, at least for LDL cholesterol reduction.

Go to http://fanaticcook.blogspot.com to view.

I think Fanatic Cook is right--despite the lack of LDL reducing effects, it doesn't necessarily mean no benefit whatsoever. Anti-coagulation and anti-inflammatory effects, in particular, are well proven.

I do think, however, that it argues more in favor of sticking to whole cloves, rather than supplements. The benefits are also likely small. I would view garlic as a soft advantage for your plaque control program. You can do fine without it. You might do slightly better with it.

Most hospitals maintain the "Saint _____" in their names, despite many having little or nothing to do with the church.

Out of 15 hospitals in my area, 13 are named after saints.

In my view, a more honest name would be something like "ABC Medical Enterprises, Inc." The profit motive, aggressive marketing tactics, and high CEO salaries would make better sense then. The trend to convert practicing physicians from professionals acting on behalf of patient welfare into paid employees would also be clearer.

Imagine Walmart were to change its name to "St. Mary's Emporium" Would it modify your perception of their business? I think it would. It would cause many people to believe that maybe their work was, at least in part, charitable and being done for the public welfare. But Walmart makes such pretense--they are in business for profit, just like all businesses.

It's time for the pretense to be dropped. Hospitals are cut-throat profit-seeking operations, operating under the guise of charitable, tax-free institutions. It's the farthest thing from the truth.

You can always count on Dr. John Cannell for unique perspectives on vitamin D. I reprint here his unfailingly entertaining and informative Vitamin D Newsletter on whether vitamin D replacement enhances physical performance.

The whole vitamin D "discovery" sometimes worries me. Vitamin D has proven to be an unbelievable, remarkable, dramatic boon to health, including facilitation in dropping CT heart scan scores. Yet the answer was always right in front of us. It worries me that you and I might have the answer to important questions right within our grasp all along--but don't know it. What if the same were true, say, for cancer? That is, a profound answer is right there, but our eyes just pass right over it.

Anyway, we should all keep our eyes open and perhaps you and I will continue to identify the most powerful tools available that return control over heart disease to us and take it away from the perverse, procedural hospital formula that still reigns.

If you haven't done so already, be sure to visit Dr. Cannell's website, www.vitamindcouncil.com.

Peak Athletic Performance and Vitamin D

"No way doc." I had just finished telling my patient about the benefits of vitamin D, telling him he should take 4,000 IU per day, using all the techniques I had learned in 30 years of medical practice to convince someone proper treatment is important. But, he knew the U.S. government said he only needed 200 IU per day, not 4,000. He also knew the official Upper Limit was 2,000 IU a day. "What are you trying to do doc, kill me?" I told him his 25(OH)-vitamin D blood test was low, only 13 ng/ml. He had read about that too, in a medical textbook, where it said normal levels are between 10 and 40 ng/ml. "I'm fine doc;" adding "Are you in the vitamin business?" I explained I was not; that the government used outdated values; that recent studies indicate ideal 25(OH)D levels are about 50 ng/ml; and that they indicated that he needed about 4,000 IU per day to get his level up to 50. "No thanks doc, I'm fine."

So I tried a different tact. I brought him copies of recent press articles. "Look," I said, "look at these." Science News called vitamin D the Antibiotic Vitamin. The Independent in England says vitamin D explains why people die from influenza in the winter, and not the summer. U.S. News and World Report says almost everyone needs more. Newsweek says it prevents cancer and helps fight infection. In four different recent reports, United Press International says that: it reduces falls in the elderly, many pregnant women are deficient , it reduces stress fractures, and that it helps heals wounds.

He glanced at the articles, showing a little interest in stress fractures. Then he told me what he was really thinking. "Look doc, all this stuff may be important to old guys like you. I'm 22. All I care about are girls and sports. When I get older, maybe I'll think about it. I'm too young to worry about it. I'm in great condition." I couldn't argue. He was in good health and a very good basketball player, playing several hours every day, always on indoor courts.

What could I do to open his eyes? As an African American, his risk of early death was very high, although the risk for blacks doesn't start to dramatically increase until their 40's and 50's. Like all young people, he saw himself as forever young. The U.S. government was no help, relying on a ten-year-old report from the Institute of Medicine that is full of misinformation.

I tired to tell him that the 200 IU per day the U.S. government recommends for 20-year-olds is to prevent bone disease, not to treat low vitamin D levels like his. I pointed out the U.S. government's official current Upper Limit of 2,000 IU/day is the same for a 300 pound adult as it is for a 25 pound toddler. That is, the government says it's safe for a one-year-old, 25-pound, child to take 2,000 IU per day but it's not safe for a 30-year old, 300-pound, adult to take 2,000 and one IU a day. I mean, whoever thought up these Upper Limits must have left their thinking caps at home. Nevertheless, nothing worked. My vitamin D deficient patient was not interested in taking any vitamin D.

What are young men interested in? I remembered that he had told me: "Sex and sports." Two years ago I had researched the medical literature looking for any evidence vitamin D enhanced sexual performance. Absolutely nothing. That would have been nice. Can you imagine the interest?

Then I remembered that several readers had written to ask me if vitamin D could possibly improve their athletic performance? They told me that after taking 2,000 to 5,000 IU per day for several months, they seemed just a little faster, a little stronger, maybe had a little better balance and timing. A pianist had written to tell me she even played a better piano, her fingers moved over the keys more effortlessly! Was vitamin D responsible for these subtle changes or was it a placebo effect? That is, did readers just think their athletic performance improved because they knew vitamin D was a steroid hormone precursor (hormone, from the Greek, meaning "to set in motion")?

The active form of vitamin D is a steroid (actually a seco-steroid) in the same way that testosterone is a steroid and vitamin D is a hormone in the same way that growth hormone is a hormone. Steroid hormones are substances made from cholesterol, which circulate in the body, and work at distant sites by "setting in motion" genetic protein transcription. That is, both vitamin D and testosterone regulate your genome, the stuff of life. While testosterone is a sex steroid hormone, vitamin D is a pleomorphic (multiple function) steroid hormone.

All of a sudden, it didn't seem so silly. Certainly steroids can improve athletic performance although they can be quite dangerous. In addition, few people are deficient in growth hormone or testosterone, so when athletes take sex steroids or growth hormone they are cheating, or doping. The case with vitamin D is quite different because natural vitamin D levels are about 50 ng/ml and, since almost no one has such levels, extra vitamin D is not doping, it's just good treatment. I decided to exhaustively research the medical literature on vitamin D and athletic performance. It took me over a year.

To my surprise, I discovered that there are five totally independent bodies of research that all converge on an inescapable conclusion: vitamin D will improve athletic performance in vitamin D deficient people (and that includes most people). Even more interesting is who published this literature, and when. Are you old enough to remember when the Germans and Russians won every Olympics in the 60's and 70's? Well, it turns out that the most convincing evidence that vitamin D improves athletic performance was published in old German and Russian medical literature.

With the help of my wife and mother-in-law, both of whom are Russian, and with the help of Marc Sorenson, whose book Solar Power is a must read, I finally was able to look at translations of much of the old Russian and German literature. When one combines that old literature with the modern English language literature on neuromuscular performance, the conclusion is inescapable. The readers who wrote me are right.

If you are vitamin D deficient, the medical literature indicates that the right amount of vitamin D will make you faster, stronger, improve your balance and timing, etc. How much it will improve your athletic ability depends on how deficient you are to begin with. How good an athlete you will be depends on your innate ability, training, and dedication. However, peak athletic performance also depends upon the neuromuscular cells in your body and brain having unfettered access to the steroid hormone, activated vitamin D. In addition, how much activated vitamin D is available to your brain, muscle, and nerves depends on having ideal levels of vitamin D in your blood - about 50 ng/ml, to be precise.

Why would I write about such a frivolous topic like peak athletic performance when cancer patients all across this land are dying vitamin D deficient? Like many vitamin D advocates, I have been disappointed that the medical profession and the public don't seem to care about vitamin D. Maybe people, like my young basketball player, will care if it makes better athletes. So, Hey! You jocks! Listen up! I'm talking speed, balance, choice reaction time, muscle mass, muscle strength, squats, reps, etc. Important stuff. Here's the Vitamin D Council's first ever sports quiz.

1. Vitamin D-producing UVB radiation improves athletic performance and may have been widely practiced by German and Russian Olympic athletes in the 1960's and 70's.

True. I found tantalizing evidence the Russians and especially the Germans were on to this during the 60's and 70's when those two nations took turns placing number one and number two in the Olympics every year?

For example, in 1938, Russian researchers reported that a course of ultraviolet irradiations improved speed in the 100-meter dash in college students compared to matched controls, both groups undergoing daily training. Average 100-meter dash times decreased from 13.51 seconds to 13.28 seconds in the non-irradiated controls, but from 13.63 seconds to 12.62 seconds in the irradiated students. Here we see training improved times but training and irradiation improved times much more. Obviously, irradiation or vitamin D would not render the same magnitude of improvements in world-class sprinters, but they would be happy with a few milliseconds.

Gorkin Z, Gorkin MJ, Teslenko NE. [The effect of ultraviolet irradiation upon training for 100m sprint.] The Journal of Physiology of the USSR [Fiziol, z. (RSSR)] 1938; 25: 695-701. (In Russian)

If you want to know what early German thinking was on this, read this summation of the German literature:

"It is a well-known fact that physical performance can be increased through ultra-violet irradiation. In 1927, a heated argument arose after the decision by the German Swimmers' Association to use the sunlamp as an artificial aid, constituting an athletic unfairness, doping, so to speak. In 1926, Rancken had already reported the improving effect of sunlamp irradiation on muscle work with the hand-dynamo-graph. Heib observed an improvement in swimming times after repeated irradiations. In thorough experiments, Backmund showed that a substantial increase in muscle activity happens after radiation of larger portions of the body with an artificial sunlamp; that this performance increase is not caused through local - direct or indirect - effects on the musculature, but through a general effect. This general effect, triggered by ultra-violet irradiation, is caused by a systemic effect on the nervous system." (p. 17)

In 1945, two Americans measured the cardiovascular fitness and muscular endurance of 11 male Illinois subjects undergoing training in an indoor physical education class, comparing them to 10 matched controls. Both groups underwent similar physical training. Treatment consisted of ultraviolet irradiation, given in the nude, up to two minutes per session, three times per week, for ten weeks in the late fall and winter. After ten weeks, the treatment group had a 19% standard score gain in cardiovascular fitness compare to a 2% improvement in the control students. To regular readers of this newsletter, it should come as no surprise that the un-irradiated control group reported twice as many viral respiratory infections as the treatment group.

Allen R, Cureton T. Effects of Ultraviolet Radiation on Physical Fitness. Arch Phys Med 1945: 10: 641-44.

In 1952, the German sports medicine researcher, Spellerberg, reported on the effects of wholesale irradiation of athletes studying and training at the Sports College of Cologne - including many elite athletes - with a "central sun lamp." He irradiated the athletes in their bathing suits, on both sides of their bodies, for up to ten minutes, twice a week, for 6 weeks. He reported a "convincing effect" on athletic performance and a 50% reduction in sports injuries. Results were particularly impressive for swimmers, soccer, handball, hockey, and tennis players, as well as for boxers and most track and field athletes. He reported that irradiation leading to burns, further irradiation of athletes having achieved peak performance, and irradiation within 24 hours of competition, all impaired athletic performance. Their results were so convincing, the Sports College of Cologne officially notified the "national German and International Olympic committee." (p. 570)

In 1952, Ronge exposed 120 German schoolchildren to UV lights installed in classrooms and compared them to 120 un-irradiated control children. Over a two-year period - excluding summer vacations - he tested both groups with a series of six cardiovascular fitness tests using a bike ergometer. Un-irradiated children showed a distinct seasonality in fitness, with the highest values right after summer break and the lowest values in the spring. Treated children showed no seasonal differences in physical performance. Differences in work performance between the irradiated and un-irradiated children were most conspicuous in the spring with 56% difference between the two groups. In a final experiment, he gave 30 children in the control classrooms 6.25 mg (250,000 IU) of vitamin D as a single dose in February and found their performance had "increased considerably," one month later but did not report the actual numbers. He concluded that vitamin D, either as a supplement or induced via UV irradiation, improved physical performance.

In 1954, another researcher, at the Max-Planck Institute for Industrial Physiology in Dortmund, Germany, administered three different wavelengths of UV light over 8 weeks to university students. He found that ultraviolet light in the vitamin D-producing UVB range was consistently effective in reducing resting pulse, lowering the basal metabolic rate, and increasing athletic performance. UVA had no effect; interestingly, artificial UVC irradiation (the atmosphere normally completely filters out UVC radiation and thus it's not naturally present on earth) also gave some positive results.

Lehmann G. [Significance of certain wave lengths for increased efficacy of ultraviolet irradiation.] Strahlentherapie. 1954 Nov;95(3):447-53. [In German]

In 1956, Hettinger and Seidel irradiated seven subjects in two different experiments: athletic performance on bike-ergometers and forearm muscle strength. They found that UV radiation induced a significant improvement in both muscle strength and athletic performance.

Hettinger T, Seidl E. [Ultraviolet irradiation and trainability of musculature.] Internationale Zeitschrift für angewandte Physiologie, einschliesslich Arbeitsphysiologie 1956; 16: 177-83. [In German]

Another German researcher, at the Institute for Medical Physics and Biophysics at the University of Gottiingen, studied reaction times (the time needed to recognize a light and switch it off) during October and November in a series of controlled experiments on 16 children and an unspecified number of adults. He first controlled for practice effects (getting better by practicing) and then administered nine full-body UV radiation treatments over three weeks to the two treatment groups, using placebo radiation in the two control groups. UV radiation improved choice reaction time by 25% in children and 20% in adults while reaction time worsened in controls. The improvements in the irradiated groups peaked at the end of the three weeks of UV treatments and reverted to baseline levels three weeks later. In the two control groups, he found distinctly improved reaction times in the sunnier months.

The next study threw me because it was very well conducted, meticulously designed, and completely negative. In 1963, Berven reported on the effects of ultraviolet irradiation and vitamin D supplementation in a group of 30 Stockholm schoolchildren, aged 10 -11, comparing them to appropriate controls. He found no seasonality of fitness in the control group and no effect from either irradiation or two different vitamin D supplementation protocols (1500 IU of cholecalciferol daily for two months and a single dose of 400,000 IU of ergocalciferol) on performance on a bike ergometer.

Berven H. The physical working capacity of healthy children; seasonal variations and effect of ultraviolet irradiation and vitamin-D supply. Acta paediatrica. Supplementum 1963; 148: 1-22.

However, two things were not right and got me thinking. One, Berven found no seasonality of physical fitness and was the only author who found no such seasonal variations in athletic performance. Second, he found no effect from irradiation, again, the only author. Then I realized he was working with Swedish children in the late 1950's. Supplementation of children with high doses of vitamin D - often as cod liver oil - was routine in Scandinavia in the past, particularly in children. For example, in neighboring Finland, the official recommended daily dose of vitamin D for children - including infants - was 4,000 IU per day until 1964, when authorities reduced it to 2,000 IU/day. (That's right, you read that correctly, 4,000 IU per day for infants, which is too much by the way.)

In 1975, Finnish authorities reduced it to 1,000 IU per day, and, in 1992, to 400 IU per day. I emailed Professor Elina Hypponen who confirmed that the Swedish recommendations were similar to the Finnish ones. Therefore, it seems highly unlikely that many of Berven's Swedish children, studied in 1958 and 1959, all from "families with a good standard of living," were vitamin D deficient. Therefore, this study showed that vitamin D will not improve athletic ability in vitamin D replete people. That's very important because it indicates more is not necessarily better. More is only better if you are not taking enough.

Hypponen E, et al. Intake of vitamin D and risk of type 1 diabetes: a birth-cohort study. Lancet. 2001 Nov 3;358(9292):1500-3.

In the 1960's, three American researchers conducted experiments with university students. Rosentswieg studied the effects of a single six-minute dose of UV light on each side of the trunk in 23 college women, recording changes in various tests of muscle strength at one and five hours. He found a trend towards significance after five hours in white but not African American students. In 1968, Cheatum found that a six-minute administration of UV light, on each side of the trunk, increased the speed of 15 college women in the 30-yard dash. In 1969, Rosentswieg found a six-minute dose of UV light, on each side of the trunk, finding improved performance on a bicycle ergometer in college women. However, unlike the Germans and Russians, I could find no evidence that any of these American findings interested any American professionals involved in the care or training of athletes.

2. Athletic performance peaks in the summer when vitamin D levels peak, and is at its lowest in the winter when vitamin D levels are at their lowest.

A. True
B. False

True. The studies below - all I could find in the literature - show tests of physical performance peak in the summer, when vitamin D levels peak, start to decline in early autumn, as vitamin D levels decline, and athletic performance reaches its lowest point in late winter, when vitamin D levels bottom out. However, it is reasonable to assume that any associations between athletic performance and summer season may be due to "reverse causation." That is, improved athletic performance in the summer might be secondary to increased outdoor physical and recreational activity in the warmer weather with an indoor sedentary lifestyle during the colder months. Maybe people have better athletic ability in the summer because they exercise more. If that is true - and using the same logic - athletic performance should not begin to decline until late autumn, because at most temperate latitudes early fall weather is ideal for outdoor physical activities.

However, some of the studies below controlled for seasonal variations in time spent exercising. Furthermore, besides a consistent positive association of summer season with improved athletic performance, the below studies found an abrupt - and unexplained - reduction in athletic performance beginning in the early fall - when vitamin D levels decline - but when the weather is ideal for outdoor activities.

For example, in 1956, German researchers found a distinct seasonal variation in the trainability of musculature, studying wrist flexor strength in 21 German subjects undergoing daily training. They found highly significant seasonal differences with peak performance during the later part of the summer, nadirs in the winter, and an unexplained sharp autumn decline beginning in October.

Hettinger T, Muller EA. Seasonal course of trainability of musculature. Int Z Angew Physiol. 1956;16(2):90-4.

A study of Polish pilots and crew found physical fitness and tolerance to hypoxia were highest in the late summer with an unexplained sharp decline starting in September. The authors hypothesized that seasonal variations in an unidentified hormone best explained their results.

Cumulative work ability among 1,835 mainly sedentary Norwegian men during bicycle exercise tests showed an August peak, a sharp decline starting in the autumn, and a wintertime nadir. There were no seasonal changes in body weights, as might be expected if more caloric-demanding recreational activity during the sunnier months explained their results.

Koch and Raschka reviewed the mostly German literature on the seasonality of physical performance, discussing studies indicating that muscle strength and stamina peak in the late summer. The authors then attempted to control for seasonal variations in the time spent exercising by instituting a controlled yearlong training regimen, beginning in December. The training regimen consisted of at least 20 push-ups per day and 2 or 3 long-distances races per week for the entire year. They found the both the number of push-ups and muscle strength peaked in late summer followed by a rapid decline in the fall, and a nadir in the winter, despite continued training. They concluded that seasonal variations in an unidentified hormone best explained their results. In addition, by now we all know that vitamin D is a seasonal hormone, and a steroid hormone precursor to boot.

3. Vitamin D has direct muscle-building (anabolic) effects.

A. True
B. False

True, but only in vitamin D deficient subjects. Both animal and human studies have found that vitamin D directly affects muscle. That is, vitamin D increases muscle mass.

For example, Birge and Haddad found that vitamin D caused new protein synthesis in rat muscle.

Birge SJ, Haddad JG. 25-hydroxycholecalciferol stimulation of muscle metabolism. J Clin Invest. 1975 Nov;56(5):1100-7.

What about humans? In 1981, Young performed muscle biopsies on 12 severely vitamin D deficient patients before and after vitamin D treatment. They found type-II (fast-twitch) muscle fibers were small before treatment and significantly enlarged after treatment. Sorensen performed muscle biopsies on eleven older patients with osteoporosis before and after treatment with vitamin D. The percentage and area of fast twitch fibers increased significantly after treatment, despite the lack of any physical training.

Sato reported that two years of treatment with 1,000 IU of vitamin D per day significantly increased muscle strength, doubled the mean diameter, and tripled the percentage of fast-twitch muscle fibers, in the functional limbs of 48 severely vitamin D deficient elderly stroke patients. The placebo control group suffered declines in muscle strength, and in the size and percentage of fast-twitch muscle fibers.

Sato Y, Iwamoto J, Kanoko T, Satoh K. Low-Dose Vitamin D Prevents Muscular Atrophy and Reduces Falls and Hip Fractures in Women after Stroke: A Randomized Controlled Trial. Cerebrovasc Dis. 2005 Jul 27;20(3):187-192 [Epub ahead of print]

These studies clearly show that vitamin D when administered to vitamin D deficient people stimulates the growth and number of those muscle fibers critical to athletic ability, type-2, or "fast twitch," muscle fibers.

4. Many studies have found direct associations between physical performance and vitamin D levels. That is, the higher your vitamin D level, the better your athletic performance.

A. True
B. False

True. I found 13 positive studies of associations between vitamin D levels and various parameters of neuromuscular performance. However, they were all in old people. Of course, old people can be athletes too. Furthermore, age differences in physiology and pharmacology are quantitative, not qualitative. That is, what is true in old people will be true in young people, although the magnitude might be different. Higher vitamin D levels are associated with a wide variety of athletic performance but appear to have the strongest associations with balance, timing, and timed tests of physical performance.

The three largest studies had more than 7,000 elderly subjects. All found evidence of a vitamin D threshold of between 30 - 50 ng/ml, above which further improvements in athletic performance were not seen. Wicherts and her colleagues found a linear correlation between vitamin D and neuromuscular performance; scores were 78% better for those with vitamin D levels greater than 30 ng/ml compared to those with levels less than10 ng/ml.

Wicherts IS, et al. Vitamin D status predicts physical performance and its decline in older persons. J Clin Endocrinol Metab. 2007 Mar 6; [Epub ahead of print]

Professor Heike Bischoff-Ferrari, now in Switzerland, did the largest study. She and her colleagues found a strong positive correlation and suggestion of a U-shaped curve with athletic performance on one test peaking with vitamin D levels of 50 ng/ml but deteriorating at higher levels. It is interesting to speculate that levels around 50 ng/ml may be optimal for athletic performance as such levels are common in humans living in a "natural" state of sun-exposure, such as lifeguards or tropical farmers.

Interestingly, all three studies that looked for an association between mental abilities and vitamin D levels found one. A fourth study, unrelated to athletic function, also found an association. The obvious explanation for these findings is that cognitively impaired patients do not go outdoors as often as higher functioning patients and thus have lower vitamin D levels. However, Dhesi found the association after excluding all but mildly demented patients, making such an explanation more difficult. Flicker and - more recently - Przybelski and Binkley, found the association after controlling for outdoor activities, raising the possibility that the association of vitamin D levels with cognitive abilities is casual. Both the vitamin D receptor and the enzyme necessary to activate vitamin D are present in a wide-variety of human brain tissue. If vitamin D deficiency impairs cognitive abilities, it is likely that such deficiencies will also impair the brain's ability to process the complex circuits needed for peak athletic performance.

There can be no doubt that higher vitamin D levels are associated with improved athletic performance in the elderly. From what we know of physiology and pharmacology, the same associations should hold true in young people, including young athletes.

5. Numerous studies have found that vitamin D improves physical performance.

A. True
B. False.

True, but, again, most all the studies are in old persons, not young ones, and none of the studies are in world-class athletes. However, there is no medical reason why vitamin D would improve the athletic performance of vitamin D deficient old people but not vitamin D deficient young ones. Eleven studies found vitamin D improved physical performance, mainly on measures of balance and reaction time. The one study of younger subjects showed dramatic physical performance effects in 55 severely vitamin D deficient women.

In summary, five converging - but totally separate - lines of scientific evidence leave little doubt that vitamin D improves athletic performance. (I actually left out a sixth line of evidence, something a little more complicated, studies of muscle strength and vitamin D receptor polymorphisms; the two studies I could find were both positive.) Anyway, the scientific evidence that UVB radiation, either from the sun or from sunbeds, will improve athletic performance is overwhelming and the mechanism is almost certainly vitamin D production. Peak athletic performance will probably occur with 25(OH)D levels of about 50 ng/ml, whether from sun, sunbeds, or supplements.

All that is missing is a big-time professional or college team identifying and then treating their elite athletes who are vitamin D deficient. Can you imagine what such performance-enhancing effects would do for basketball players, most of who are African American and who practice and play indoors all winter? Or gymnasts? Or weight lifters?

However, a word of caution. The above studies suggest that taking too much vitamin D (more than 5,000 IU per day) may actually worsen athletic performance. Take the right amount, not all you can swallow. Take enough to keep your 25(OH)D levels around 50 ng/ml, year round. Easier yet, regularly use the sun in the summer and sunbeds in the winter - with care not to burn. Once a week should be about right.

When you think about it, none of this should surprise anyone. Every body builder knows that steroid hormones can improve athletic performance, certainly increase muscle mass. Barry Bonds knows they increase timing and power. Moreover, activated vitamin D is as potent a steroid hormone as exists in the human body. However, unlike other steroids, levels of activated vitamin D in muscle and nerve tissue are primarily regulated by sun exposure. That's right, the rate-limiting step for the cellular function (autocrine) of activated vitamin D is under your control. It depends on how much you put in your both or go into the sun. It's ironic that many athletes now avoid the sun, organized baseball is even promoting sun avoidance and sunblocks. The ancient Greeks knew better; they had there elite athletes train on the beach and in the nude.

The medical literature indicates vitamin D levels of about 50 ng/ml are associated with peak athletic performance. Of course, recent studies show such levels are ideal for preventing cancer, diabetes, hypertension, influenza, multiple sclerosis, major depression, cognitive impairments, etc. But who cares about all that disease stuff old people get, we're talking about something really important: speed, balance, reaction time, muscle mass, muscle strength, squats, reps, etc. And guess who's now taking 4,000 IU/day? Yes he is, and he tells me his timing is better, he can jump a little higher, run a little faster, and the ball feels "sweeter," whatever that means.

The reason why I've been blogging lightly these past few days is because, as a favor, I'm covering the practice for some colleagues who I'm (very) loosely affiliated with. The time demands have been great.

Nonetheless, it is a good reminder to me just how far wrong conventional cardiology remains. Judging by what I see around me, there is a startling lack of restraint in proceeding to the catheterization laboratory. Curiously, the internists and family practitioners have been brainwashed into accepting this path. I suppose that all it takes is an occasional real "save" for these physicians to develop a fear of ever missing real disease.

What I'm seeing is just how many people presenting with chest pain or similar symptoms end up going to the cath lab. I would crudely estimate 80%. That is, once you make it past the emergency room, there's a four out of five chance that you'll end up with a heart catheterization to "be sure your heart is okay", "make certain you're not going to die of heart disease", "see if there's a ticking time bomb in your chest". You've heard all the clever, scary phrases that get tossed around to scare the pants off you and justify putting catheters in your groin.

Despite the fact that tools for heart disease prevention have improved dramatically, the volume of heart catheterizations continues to grow nationwide.

I find it shocking and unacceptable. We're currently working behind the scenes to help change this situation through education of the public. Persuade a $1 million a year cardiologist that he is overdoing procedures? Unlikely in my experience. Educate the public about the shocking over-reliance on high-revenue procedures? Perhaps more practical.

Garlic May Not Lower Cholesterol
Study Shows No Improvement in Cholesterol Levels From Raw Garlic or Garlic Supplements

Lots of reports continue to hit the press about a small study that hoped to determine whether garlic as whole cloves (4 to 6), an aqueous extract of garlic called Kyolic, or an oil extract called Garlicin (high in allicin), or placebo. No differences in lipid numbers including LDL cholesterol were observed.

(Full text at WebMD at http://www.webmd.com/cholesterol-management/news/20070226/garlic-may-not-lower-cholesterol?ecd=wnl_chl_030507. You may be required to log in or register.)

I believe that the researchers were sincere in their effort to follow an honest, scientfically sound clinical trial design. I'm personally not that surprised. The effect in prior studies has been modest, sometimes none. Does that mean that we should ignore the other studies that suggest there may be modest blood-thinning, anti-inflammatory, blood pressure-reducing, and cancer-preventing properties? No, it does not. Dr. Matt Budoff at UCLA even published a very small study in about 20 people that suggested a slowing of plaque growth by using Kyolic in persons tracked by CT heart scans.

Nonetheless, garlic is, at best, probably no more than a source of small benefits. The biggest fallout from this kind of report, however, is not the neutral results from garlic, but from the open door the drug companies sense when this happens.

If you read the WebMD report, you'll notice all sorts of advertisements from drug companies for statin cholesterol drugs ("Cholesterol health center"; "Understanding Cholesterol Numbers"; "There are two sources of cholesterol: food and family"), Niaspan (which I used to support but have been discouraged by the Kos companies excessively profiteering methods and recent big Wall Street sellout).

It doesn't follow. The failure of one nutritional strategy to reduce LDL does nothave to trigger a run to the drugs. Don't fall for it. Drugs have their place. So do supplements and food choices, which can be very powerful. Drug manufacturers and their marketing people salivate when something like this comes along, an open invitation to say, "If garlic doesn't work, _____ sure does."

Jason came to the office because of chest pain. At 34 years old, he works as manager of a (non-fast food) restaurant, but indulges in lots of the odds and ends. Among his indulgences: Diet Coke.

Every time he'd have a diet Coke, he'd have chest pain. Not drinking diet Coke--no chest pain. If Jason drank coffee, no chest pain. Other foods, no chest pain. Anyway, just eliminating the diet Coke seemed to do the trick. (Aspartame?)

Anyway, that's not why I tell you Jason's story. In the midst of his evaluation, an echocardiogram showed a mildly enlarged aorta, measuring 4.0 cm in diameter. So we obtained lipoproteins. Jason showed lipoprotein(a) and small LDL particles, the dreaded duo. We talked about how to correct this pattern. Among the strategies we discussed was niacin.

But what bothered me was that neither of Jason's parents had a diagnosis of heart disease. Jason had to have gotten Lp(a) from either his mother or father, since you obtain the gene from one or the other parent. You cannot acquire Lp(a). So one of Jason's parents was sitting on a genetic time bomb of unrecognized Lp(a) and hidden heart disease.

Because Jason's paternal grandfather had a heart attack at age 62, only Jason's Dad had the heart scan (though I urged both to get one). Score: 1483. Recall that heart scan scores >1000 carry a risk of death or heart attack of 25% per year if no preventive action is taken. Now, of course, we have to persuade Jason's Dad that a program of prevention--intensive prevention is in order, including a measure of Lp(a).

So that's the curious story of how Diet Coke probably saved Jason's Dad's life. The lesson is that if you or someone you know has Lp(a), think about their children as well as their parents, each of whom carry a 50% chance of having the pattern.

Kraft Foods, Inc. is manufacturer of Kool Aid, Oscar Mayer, Kraft Macaroni and Cheese, Velveeta, Honey Maid Grahams, and hundreds of other processed food products. Post cereals also falls under the umbrella of Kraft with products like Raisin Bran, Post Toasties, and Fruity Pebbles. Annual revenues in 2006 for Kraft: $34.4 billion. A big operation with enormous influence over our eating habits.

Nabisco is manufacturer of Oreos, Ritz Crackers, Chips Ahoy and many others. Like Kraft/Post, it is also a big player.

While Nabisco was owned for several years by tobacco giant RJ Reynolds, in 2000 it was acquired by Philip Morris, another big tobacco manufacturer.

More recently in Spring, 2007, Philip Morris (now called Altria--you'd change your name, too, if it was synonymous with dirt) spun off its Kraft subsidiary for a big profit. However, the management structures remain intertwined.

In other words, despite the shuffling of shares, the two industries, big tobacco and big food, are in many respects one and the same.

Is it any surprise that the same industry that made billions of dollars pushing addictive nicotine products responsible for the deaths of hundreds of thousands of people is now intimately involved with addictive products produced and marketed by the processed food industry?

If you believe that food manufacturers are innocently and honestly conducting their businesses, simply think back to the testimony provided in front of Congress during the tobacco industry hearings. Broad deception, concealed truths, and outright lies were commonplace. There was no conscience involved. This was about money--and lots of it.

Why should the processed food industry, intimate with the tobacco industry, be any different?

If you want control over heart disease and your heart scan score, buy produce and buy local. Spend your time in the produce aisle, not the cereal or chip aisle. Unprocessed food, unadorned by bright labels, cartoon animals, American Heart Association endorsements, that's what we should seek.

Here's a situation that crops up once in a while, occurring in perhaps 2% of heart scans.

The white within the circled area represents calcium, and thereby atherosclerotic plaque, situated immediately at the "mouth", or opening, of the the right coronary artery. What is somewhat unusual is that this plaque is not principally coronary, but aortic. That is, the plaque is mostly situated in the large vessel called the aorta. The three coronary arteries arise from the aorta.

In this instance, the aortic plaque involves the mouth of the right coronary artery. (In views not shown, the plaque also extends into the artery as well.) I call this a "double whammy" because the same plaque can post risk for heart attack and stroke.

Generally, aortic plaques pose risk for stroke. When aortic plaque fragments, little bits and pieces can travel upward to the brain and block an artery, thus a stroke.

In the coronaries, disrupted ("ruptured") plaques don't generally shower debris, but permit blood clot formation, resulting in heart attack.

This plaque, however, poses the theoretical risk of both heart attack and stroke because of its strategic location.

Should a plaque like this be handled any differently? I don't think so. But it does provide another reason to take atherosclerotic plaque in any artery seriously.

When we look back over our American nutritional history over the last 50 years, it's hard not to come to the conclusion that much of the innovation in nutrition did not come from official agencies like the Food and Nutrition Board of the Institute of Medicine, the National Academy of Sciences, the FDA, the USDA, or the AMA.

Instead, it came from the popular culture. It came from bold, extravagant claims made by maverick figures like Ancel Keys, Nathan Pritikin, Dean Ornish, and Robert Atkins. Of course, some ideas have now fallen by the wayside, dismissed in a broad American "experiment" as ineffective, impractical, or kooky. But it permitted experimentation on an extraordinary scale with millions of people following a particular strategy at a time.

The advice of the official agencies tended to be reactionary. When nutritional deficiencies (remember those?) of the early 1900s were prevalent, they issued advice on food choices to help alleviate deficiencies. When deficiency transformed into excess after World War II, "smart" food choices from food groups and "sensible eating" became the theme.

Unfortunately, the advice was always adulterated by the enormous influence of various special interests, anxious to protect their national franchise. Powerful groups like the meat industry, wheat producers, and the dairy industry all made sure they had a big hand in crafting and influencing what was told to the American people.

The result: the advice offered by official groups has always represented the compromise of what some agency wished to convey to the people and the very powerful input of industry. What if the government decided to advise us what automobile to buy? Imagine the uproar in the auto industry when Washington tells us to buy Toyota for fuel economy and reliability. How long would that advice last?

That's why almost no knowledgeable adult follows the advice of the USDA, the National Academy of Sciences, or the Food Pyramid. I believe that we all intuitively recognize that the advice is watered-down, sometimes silly, sometimes downright unhealthy.

Nonetheless, the national experiment in diet that has taken place since 1950 has led to a collective wisdom of what is good and what is bad. The most productive conversations on nutrition therefore take place outside of the USDA and Washington. It occurs, instead, in places like bookstores, websites, and the media. Of course, there's lots of misinformation and profiteering in these sectors, as well. But like the enormous force unleashed by the collective wisdom of those contributing to the Wikipedia phemonenon, we've zig-zagged to something closer to the truth than ever uttered by an official agency.

Niacin:

Over-the-counter: $2-5 per month
Prescription: $120 per month

Fish oil:

Over-the-counter: $3-6 per month
Prescription: $120 per month

Vitamin D:

Over-the-counter: $2 per month
Prescription: $70 per month

With vitamin D in particular, the prescription form is vastly inferior to the over-the-counter preparation. This is because the prescription form is ergocalciferol, or vitamin D2, not the effective human form, vitamin D3 or cholecalciferol.

When you're exposed to sun, what form of vitamin D is activated in the skin? It's all vitamin D3, no vitamin D2 whatsoever. Vitamin D3 is also far more effective than D2. People taking D3 (as long as it's oil-based) easily obtain healthy levels of vitamin D in the blood. People taking 50,000 units per day of D2 (the recommended quantity) remain miserably deficient, with minor increases in vitamin D blood levels. In short, D2 barely works at all. D3 works easily and effectively.

Moreover, D2 is the plant-based form. It is a form not found naturally in humans. D3 is the mammalian form, the same found in humans that exerts all its biologic benefits.

Then why is the prescription form of vitamin D2 (brand names Driscol and Calciferol) more expensive?

It's the same old pharmaceutical industry scam: Look for something patent protectable, regardless of whether it's superior to the non-patent protectable product, then sell it for exagerated profits. Though it is inferior and the science and clinical experience prove that it's inferior, you can still fool lots of people, including prescribing physicians. So what if you only make $50 or $100 million?

Don't fall for it. Prescription doesn't necessarily mean superior. In fact, the prescription form may be significantly inferior, as with vitamin D2. But the pharmaceutical industry carries such power and persuasion, who's going to know?

I borrowed the above comic from the website of nutritionist, more properly nutrition activist and author, Mike Adams. His website, www.newstarget.com, was a pleasant surprise.

I was actually looking for some thoughts on pharmaceutical advertising and its pervasive and destructive effects and came across one of Adam's reports, Pharmaceutical television advertising is a grand hoax at http://www.newstarget.com/021526.html. The piece is a rant against the pharmaceutical industry's constant bombardment of the media, who have also been co-opted into their service, enticed by the enormous advertising revenues the drug industry brings.

But I was surprised to find an insightful, informative website on health issues, particularly healthy eating that rejects the manufactured food industry's intensive effort to persuade us to eat their products. While I don't agree with everything Adams has to say, his website provides some great food for thought. He also provides lots of downloadable information.

There's also some great laughs at his poke at the pharmaceutical industry with his Disease Mongering Engine at http://www.newstarget.com/disease-mongering-engine.asp, in which you get to create your own diseases. I got a real kick out of this.

The NY Times ran an article called

With Rise in Radiation Exposure, Experts Urge Caution on Tests at

http://www.nytimes.com/2007/06/19/health/19cons.html?_r=1&adxnnl=1&oref=slogin&adxnnlx=1182254102-vQpytpx6W/Z9gvAaNPDZvA

“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.”

Where do CT heart scans fall?

Let's first take a look at exposure measured for different sorts of tests:

Typical effective radiation dose values

Computed tomography Milliseverts (mSv)

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 Milliseverts (mSv)

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

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.

A heart scan on a 16- or 64-slice multidetector device, your exposure is 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 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 legimate medical questions. They are not screening tests to be applied broadly and used year after year.

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.

Detail on radiation exposure with CT coronary angiograms on multidetector devices can be found at Hausleiter J, Meyer T, Hadamitzyky M et al. Radiation Dose Estimates From Cardiac Multislice Computed Tomography in Daily Practice: Impact of Different Scanning Protocols on Effective Dose Estimates. Circulation 2006;113:1305-1310, one of several studies on this issue.

In 1994, the Lyon Heart Study demonstrated a 50-70% reduction in coronary events in participants who followed a diet rich in vegetables, olive oil, fish, nuts, red wine, and enjoyed meals as a family activity. Various other studies have documented similar phenomena with less metabolic syndrome, better lipid patterns, less obesity with the Mediterranean lifestyle.

There are two fundamental differences between the Mediterranean diet and the diet advocated by the American Heart Association (AHA) for people with heart disease: the Mediterranean diet uses olive oil more liberally, such that fat calories can reach 40% of total; and, unlike the AHA diet, processed foods are not a part of the Mediterranean diet. Greeks, for instance, are far less likely to eat Count Chocula cereal for breakfast, or snack on Healthy Choice Premium Caramel Swirl Sandwich (ice cream sandwiches) or Malt-O-Meal Honey Nut Scooters. All three of these foods on listed on the AHA Heart-Check Mark heart-healthy program.

In other words, remove all the processed foods, and the AHA diet pretty closely resembles the Mediterranean diet. There are differences but they tend to be relatively small. If the only major difference is the presence of processed foods, wouldn't you therefore expect the AHA to embrace the Mediterranean diet?

Here's what their official stand on the Mediterranean diet states:

Does a Mediterranean-style diet follow American Heart Association dietary recommendations?

Mediterranean-style diets are often close to our dietary recommendations, but they don’t follow them exactly. In general, the diets of Mediterranean peoples contain a relatively high percentage of calories from fat. This is thought to contribute to the increasing obesity in these countries, which is becoming a concern.

The AHA is actually lukewarm towards the diet that was the first to show a dramatic decrease in heart attack and death. Why?

The answer is obvious, once cast in this light. To wholeheartedly endorse the Mediterranean diet might be seen as an indirect rejection of American processed foods. You know, the foods that have caused an extraordinary and unprecedented epidemic of obesity in the U.S., the foods that are manufactured by ConAgra, General Mills, Kelloggs--all also major financial contributors to the AHA, according to the AHA Annual Report.

I tell my patients: If you want heart disease, follow the American Heart Association diet. In my view, it is a diet founded on politics and money, not on health. How else could Cocoa Puffs be regarded as heart healthy?

Imagine we could send you back in a time machine to 50,000 BC.

However, our agreement: no modern tools or equipment. Just your brain, hands, and legs. And your landing spot will be tropical or semi-tropical, the same climate that humans spent much of their evolutionary time in.

Not only might you rub elbows with contemporaries like homo erectus and neanderthalensis, you'd also have to fend for your life and survival.

To eat, you will have to chase and kill wild game, all with your bare hands or crude tools crafted from sticks and stones. You will have to learn what wild berries, roots, and plants are edible and distingusih them from those that make you retch, make your bowels run, or kill you. You won't be able to cultivate grain, at least for a good long time, since you don't have a community that makes such an undertaking easier.

Instead, you are constantly on the run, from the moment you awake until you finally settle back as the sun sets, hopefully with a full stomach, but often empty and growling, anticipating the hunt and forage of tomorrow.

You are outdoors all day, except for the period when you hide in your cave or self-made shelter. You wear what little clothing you can make yourself from your kills, a skin or two. Your skin becomes a dark brown, a 5 foot 10 inch male will weigh 140 lbs, a 5 foot 5 inch woman 95 lbs. There are obvious downsides: your teeth will rot, you will be prone to infections, and predators view you as fair game.

But the result will be that many chronic diseases of modern life will no longer be worries for you. Heart disease? Highly unlikely. Do you need vitamin D? No, because you are outdoors virtually all day with most of your body surface area exposed to sun. Omega-3 fatty acids? You get those from the wild game you eat, since they have higher omega-3 content feeding in the wild, not eating corn like modern livestock. Since your body fat is minimal, just enough for survival, you don't need niacin.

In other words, many of the strategies of the Track Your Plaque program are modern necessities, responses to the "deficiencies" of modern life. Of course, I don't really have a time machine. I also doubt that you wish to hunt wild game every day, forage for plants and roots, run nearly-naked in the sun. You probably also have become accustomed to brushing your teeth and not viewing every animal as a potential threat to your life.

Nonetheless, I find this an interesting exercise for understanding the role of all the tools we use in the Track Your Plaque program for plaque control.

When I first met Hank, I immediately sensed it: anger, hostility, fear. His heart scan score of 685 just made it worse.

He didn't want to be there talking to me. His wife was giving him a hard time. Work was a constant source of irritation. The receptionist at the front desk screwed up his paperwork. Our office charges were too much.

In short, Hank was a pessimist. A bad one.

All the nutrition information out there is bunk. Only he knew how he should eat right. It's stupid to take a lot of fish oil. "You want me to grow gills?"

Among the parameters we use in the Track Your Plaque program is blood pressure during exercise, which provides a surrogate measure of blood pressure during emotional stress, anxiety, etc. "No, I don't need that. I already exercise." No amount of justification could change his mind. "A guy at work had a stress test. They said everything was fine, then Bang! He drops dead. What good is that?"

Hank did go along with a few pieces of advice.

A repeat heart scan 12 months after the first: 870, a 27% per year rate of increase. That's about what would happen if Hank had done nothing, had taken no action to try and stop or reduce his heart scan score.

I don't know if Hank will ever succeed in dropping his score. In fact, I suspect that he will fail, meaning that plaque will grow and he will eventually, perhaps in a year, two or three, require several stents, heart bypass, or have a heart attack. In other words, Hank's pessimism is a self-fulfilling phenomenon: If he believes he will fail, he will. If he believes the world is a rotten place, it is.

Is it possible to "cure" someone like Hank of his deeply-rooted pessimistic attitudes? I don't know of any easy solutions for someone with attitudes as deeply-ingrained as Hank's. (See my prior post, "Cure for pessimism?" at http://heartscanblog.blogspot.com/2007_05_01_archive.html.)

I believe it does help to make someone aware of their attitudes and that it does indeed exert ill health-effects--if they will believe it. But this is a very tough nut to crack.

A review of the effects of Coenzyme Q10 (CoQ10) on the muscle aches and weakness (myopathy) of statin drug therapy was just published in the Journal of the American College of Cardiology.

(Marcoff L, Thompson PD. The role of coenzyme Q10 in statin-associated myopathy. J Amer Coll Cardiol 2007;49(23):2231-2237.)

This is not a study, but a review of the existing scientific and clinical data available on this topic. The study authors conclude with a lukewarm statement:

". . .there is insufficient evidence to prove the etiologic [causal] role of CoQ10 deficiency in statin-associated myopathy and that large, well-designed clinical trials are required to address this issue. The routine use of CoQ10 cannot be recommended in statin-treated patients. Nevertheless, there are no known risks to this supplement and there is some anecdotal and preliminary trial evidence of its effectiveness. Consequently, CoQ10 can be tested in patients requiring statin treatment, who develop statin myalgia, and who cannot besatisfactorily treated with other agents. Some patients may respond, if only via placebo effect."

Should the media get hold of this report, be prepared for the usual "Nutritional supplement no help for drug toxicity" headlines, or "Yet another nutritional supplement shows no benefit" with parallels drawn to vitamin C or E.

There are several issue that need to be factored into the discussion:

1) This is not a study, just a review. Thus, any biases of the authors are more likely to exert themselves.

2) The understanding of CoQ10 absorption among different preparations may be an issue. I just received a mailing from Life Extension that made extravagant claims about the superior absorption of ubiquinol, to be distinguished from ubiquinone, the more common form. They claim that eight-fold increased absorption and blood levels of CoQ10 are achievable with ubiquinol. Unfortunately, virtually all the supportive data are unpublished, proprietary observations, i.e., generated by companies who make or sell it. This is as reliable as drug manufacturers who publish glowing reports on their own drugs--perhaps it's true, but it requires unbiased corroboration.

3) Despite the lack of a large, well-funded clinical trial (all are small), the issue continues to live and breathe because of the powerful anecdotal experience.

In our experience, CoQ10 does work. It doesn't work all of the time, perhaps just 80-90% of the time. It does generally require higher doses (100 mg per day, occasionally more). It very clearly must be an oil-based gelcap (just like vitamin D) to work; capsules containing powder do not work.

It's difficult to doubt when someone starts a statin drug, develops the muscle aches and weakness, begins CoQ10 and obtains distinct relief, stops CoQ10 and aches and weakness return, then only to go away again with resumption of CoQ10 . I've seen this countless times.

We do need better information on CoQ10. There's no doubt about it. For people who obtain benefit from statin therapy, I think CoQ10 remains a useful solution. A better solution would be to get rid of the offending drug. But that's not always possible--e.g., LDL cholesterol 190 mg/dl despite the best diet and "adjunctive" food effort. Then CoQ10 can be very useful.
