Lipoprotein testing

This is an update of a post I made about a year ago. However, I'm reposting it since the question comes up so often.


How can I get my lipoproteins tested?
This question came up on our recent online chat session and comes up frequently phone calls and e-mails.

If lipoprotein testing is the best way to uncover hidden causes of coronary heart disease, but your doctor is unable, unknowledgeable, or unwilling to help you, then what can you do?

There are several options:

1) Get the names of physicians who will obtain and interpret the test for you. That’s the best way. However, it is also the most difficult. Lipoprotein testing, despite over a decade of considerable scientific exploration and validation in thousands of research publications, still remains a sophisticated tool that only specialists in lipids will use. But this provides you with the best information on you’re your lipoproteins mean.
2) If you don’t have a doctor who can provide lipoprotein testing and interpretation, go to the websites for the three labs that actually perform the lipoprotein tests: www.liposcience.com (NMR); www.berkeleyheartlab.com (electropheresis or GGE); www.atherotech.com (ultracentrifugation). None of them will provide you with the names of actual physicians. They can provide you with the name of a local representative who will know (should know) which doctors in your area are well-acquainted with their technology. I prefer this route to just having a representative identify a laboratory in your area where the blood sample can be drawn, because you will still need a physician to interpret the results¾this is crucial. The test is of no use to you unless someone interprets it intelligently and understands the range of treatment possibilities available. Don’t be persuaded by your doctor if he/she agrees to have the blood drawn but has never seen the test before. This will be a waste of your time. That’s like hoping the kid next door can fix your car just because he says he fixed his Mom’s car once. Interpretation of lipoproteins takes time, education, and experience.

3) Seek out a lipidologist. Lipidologists are the new breed of physician who has sought out additional training and certification in lipid and lipoprotein disorders. Sometimes they’re listed in the yellow pages, or you can search online in your area. One drawback: Most lipidologists have been heavily brainwashed by the statin industry and tend to be heavy drug users.

4) Contact us. I frankly don’t like doing this because I feel that I can only provide limited information through this method and, frankly, it is very time consuming. I provide a written discussion of the implications and choices for treatment with the caveat to discuss them with your doctor, since I can’t provide medical advice without a formal medical relationship. We also charge $75 for the interpretation. But it’s better than nothing.

5) Make do with basic testing. Basic lipids along with a lipoprotein(a), C-reactive protein, fibrinogen, and homocysteine would provide a reasonable facsimile of lipoprotein testing. You’ll still lack small LDL and postprandial (after-eating) information, but you can still do reasonably well if you try to achieve the Track Your Plaque targets of 60-60-60. It’s sometimes a necessary compromise.

Our discussions on the Track Your Plaque Forum have impressed me with the difficulty many people encounter in getting lipoproteins drawn and interpreted. Some of our Members have been very resourceful identifying blood draw laboratories around the country, such as Lab Safe, that will at least provide the blood draw service.

I wish it was easier and we are working on some ideas to facilitate this nationwide. It will take time.

In 20 years, this will be a lot easier when doctors more commonly use lipoprotein testing. But for now, you can still obtain reasonably good results choosing one of the above alternatives.

Is it exercise or diet?

Wayne, a 61-year old retired school superintendent, had been an exercise fanatic all his adult life. If not running long distances and occasional marathons, he'd bike up to 70 miles a day. He did this year-round. In cold weather, he set his bicycle up on an indoor device and also ran on a treadmill and added weight training.

That's why it was kind of surprising that he sported a large belly. At 5 ft 8 inch and 190 lbs, that put his Body Mass Index (BMI) also high at 28.8 (desirable <25). You'd think that vigorous, almost extreme, exercise like this would guarantee a slender build.

Wayne also had lipoproteins to match: triglycerides 205 mg/dl, LDL 176 mg/dl but LDL particle number much higher at 2403 nmol/l (an effective LDL of 240 mg/dl); 75% of LDL particles were small.

I asked Wayne about his diet. "I eat healthy. Cheerios for breakfast usually. Some days I'll skip breakfast. Lunch is almost always a sandwich: tuna, turkey, something like that on whole wheat bread or a whole wheat bagel. Chips, too, but I guess that's not too healthy. Dinners vary and we eat pretty healthy. Almost never pizza or junk like that."

"Pasta?" I asked.

"Oh. sure. Two or three tiems a week. Always whole wheat. With a salad."

Wayne was well aware of the conventional advice for whole grains and, indeed, had been trying to increase his intake, particularly since his basic cholesterol numbers had been high in past. To his surprise, the more he tried at diet, the more LDL seemed to go up, as did triglycerides.

I see this situation every day: The obsession with processed carbohydrate foods, worsened by the message perpetuated by the American Heart Association, the USDA Food Pyramid, Kraft, Kelloggs, Post, etc. Eat more fiber, eat whole grains.

NY Times columnist, Jane Brody, chronicles her (embarassing) mis-adventure following the same mis-guided advice in Cutting Cholesterol, an Uphill Battle.

According to the USDA Food Pyramid, Wayne is not getting enough grains and whole grains, particularly since he is highly physically active. Consistent with the message given by the food industry: "Eat more!"

The food industry-supported Whole Grain Council advises:

Whole Grains at Every Meal
The US Dietary Guidelines recommend meeting the daily requirement by eating three "ounce-equivalents" of breads, rolls, cereals or other grain foods made with 100% whole grains. A slice of bread or a serving of breakfast cereal usually weighs about an ounce.

Want an easier way to think about it? Just look at your plate at each meal, and make sure you've included some source of whole grains. That's why our slogan is "Whole Grains at Every Meal."



By this scheme, if you are overweight, it's because you lack fiber and you're too inactive. "Get up and go!" It's not the diet, they say, it's you!

See through this for what it is: Nonsense. Wayne was overweight, packing 20 extra pounds in his abdomen from his over-dependence on processsed carbohydrates--"whole grains"--not from inactivity.

Instant heart disease reversal


What if reversal of heart disease--regression of coronary atherosclerotic plaque--were achievable instantly? Just add water and--voila!!

To my knowledge, it is not--yet. But I sometimes play with this idea in my head. I could imagine that such a program would consist of a few essential elements:

--A fast or semi-fast, or at least a very spare diet, over a period like 10 days to promote net catabolism. It is also supremely anti-inflammatory to restrict calories.

--High-dose vitamin D, e.g., 20,000 units per day of D3 to fully replenish depleted stores and achieve all the metabolism-correcting effects of D3 restoration.

--EPA + DHA at a higher than usual dose with frequent throughout-the-day dosing to encourage replacement of cellular lipid constituents with the more stable omega-3 fraction of fatty acids.

Beyond this, I'm uncertain. What role l-arginine, statins, niacin . . . conjugated linoleic acid? ApoA1 Milano infusions?

This is simply whimsical at this point. I don't know if such an approach would work. But if it did, you might imagine that it would offer an opportunity--for the properly motivated--as an alternative treatment for angina, advanced coronary disease, a means to pull someone back from the brink.

With the insights gained from our slow-but-powerful Track Your Plaque approach, perhaps we will also gain insights into how to accelerate such a process of reversal so that it is achievable in days, rather than months or years.

The small LDL epidemic

Ten years ago, small LDL was fairly common, affecting approximately 50% of the patients I'd see. For instance, an LDL particle number of 1800 nmol/l would be 40-50% small LDL in about half the people.

But in the last few years, I've witnessed an explosion in the proportion of people with small LDL, which now exceeds 80-90% of people. The people who show small LDL also show more severe patterns. 80-90% small LDL is not uncommon.

Why the surge in the small LDL pattern? Two reasons: 1) The extraordinary surge in excess weight and obesity, both of which favor formation of small LDL particles, and 2) over-reliance on processed carbohydrates, especially wheat-based convenience foods.

The constant media din that parrots such nonsense as the report on CNN Health website, Healthful Breakfast Tips to Keep You Fueled All Day, helps perpetuate this misguided advice. The dietitian they quote states:

"If you don't like what you're eating, you won't stick with it. If your choices aren't the most nutritious, small tweaks can make them more healthful. For example, if you have a sweet tooth in the morning, try a piece of nutty whole-grain bread spread with a tablespoon each of almond butter (it's slightly sweeter than peanut butter) and fruit preserves instead of eating foods that offer sweetness but little nutritional benefit, like doughnuts or muffins. If you enjoy egg dishes but don't have time to prepare your favorite before work, try microwaving an egg while toasting two slices whole wheat or rye (whole-grain) bread. Add a slice of low-fat cheese for a healthful breakfast sandwich that's ready in minutes. And don't overlook leftovers. If you feel like cold pizza (which contains antioxidant-filled tomato sauce, calcium-rich cheese, and lots of veggies), have it. It's a good breakfast that's better than no breakfast at all."

It sure sounds healthy, but it's same worn advice that has resulted in a nation drowning in obesity. The food choices advocated by this dietitian keep us fat. It also perpetuates this epidemic of small LDL particles.

If you have small LDL and its good friend, low HDL, it's time for elimination of wheat products, not some politically-correct silliness about increasing fiber by eating whole grains. Whole grains create small LDL! Or, I should say, what passes as whole grains on the supermarket shelves.

For some helpful commentary on this issue, see Fanatic Cook's latest post, Playing with Grains.

Mini-dose CTA?

I caught this little news report in the online edition of Canyon News , an LA paper, under the title Cedars-Sinai Develops Test to Prevent Heart Attacks .

They report that Dr. Daniel S. Berman M.D., chief of Cardiac Imaging and Nuclear Cardiology at Cedars-Sinai, reports that a new method of performing CT coronary angiography, "mini-dose CTA," has been developed that allows both coronary calcium scoring as well as CT coronary angiography (CTA) at a dose as low as 10% of standard dose. No technical details were provided.

Now, that may be worth knowing more about. If this is true, then CTA may indeed be useful as a "screening" procedure. However, we are going to need to know more: What devices are capable of doing this, what settings on the devices were used, etc. It does indeed come from a reputable source in Dr. Dan Berman, who is well known in nuclear cardiology circles.

We will try and dig for info. Stay tuned.

Wheat-free and weight loss

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?

John Cannell on Vitamin D

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)


Parade GW, Otto H. Die beeinflussung der leistungsfahigkeit durch Hohensonnenbestrahlung. Zeitschrift fur Klinische Medizin (Z Klin Med),1940;137:17-21 [In German]


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.

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.

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.

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.


Kwarecki K, Golec L, Klossowski M, Zuzewicz K. Circannual rhythms of physical fitness and tolerance of hypoxic hypoxia. Acta Physiol Pol. 1981 Nov-Dec;32(6):629-36.


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.


Erikssen J, Rodahl K. Seasonal variation in work performance and heart rate response to exercise. A study of 1,835 middle-aged men. Eur J Appl Physiol Occup Physiol. 1979 Oct;42(2):133-40.


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.

Sorensen OH, Lund B, Saltin B, Lund B, Andersen RB, Hjorth L, Melsen F, Mosekilde L. Myopathy in bone loss of ageing: improvement by treatment with 1 alpha-hydroxycholecalciferol and calcium. Clin Sci (Lond). 1979 Feb;56(2):157-61.


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.

Przybelski RJ, Binkley NC. Is vitamin D important for preserving cognition? A positive correlation of serum 25-hydroxyvitamin D concentration with cognitive function. Arch Biochem Biophys. 2007 Jan 8;

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.

Watch your groin

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 and cholesterol--Does everyone now need Lipitor?

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."

Diet Coke saves father's life

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.

Beware the "false positive" stress test

There's a widely-known (among cardiologists) problem with nuclear stress tests. It's called the "false positive." (Nuclear stress tests are known as stress Cardiolites, stress thalliums, stress Myoviews, persantine stress tests, adenosine stress tests)

Stress tests, nuclear and otherwise, are helpful for identifying areas of poor blood flow. If an area of poor blood flow is detected and the area is substantial, then there may be greater risk of heart attack and other undesirable events in the relatively near future.

What "false positive" means is a stress test that shows an abnormality but it's not true--it is falsely abnormal. There are a number of reasons why this can happen. The problem is that this phenomenon is very common. Up to 20% of nuclear stress tests are false positives.

There are indeed situations where there may an abnormality and it is not clear whether it is true or false. This may lead to a justifiable heart catheterization or CT coronary angiogram. But, given the extraordinary number of false positives, there's a lot of gray in interpreting these tests. Hospital staff, in fact, call nuclear medicine "unclear" medicine. It's common knowledge that you can often see just about anything you want to see on a nuclear image of the heart. Abnormalities in the bottom of the heart, the "inferior" wall, are especially common due to the overlap of the diaphragm with the heart muscle, yielding the appearance of reduced blood flow. Defects in the front of the heart heart are common in females with large breasts for the same reasons.

The problem: The uncertainty inherent in nuclear stress tests opens the door to the unscrupulous or lazy practitioner. Any blip, tick, or imperfection on the nuclear images serve as carte blanche to drag you into the hospital for procedures.

This abusive practice is, in my experience, shockingly common for two reasons: 1) It pays better to do heart catheterizations, and 2) Defensive medicine.

What's the disincentive? Only doing the right thing and maintaining a clear conscience. Slim reasons for many of my colleagues--and a lot less money.

If you are without symptoms and feel fine, and a nuclear stress test is advised by your doctor, followed by a discussion of an abnormality, insist on a discussion of exactly what is abnormal, just how abnormal, and what the alternatives might be.

Magnesium is kind of boring. So most people don't pay too much attention to it.

Magnesium can be important, however. I saw an interesting phenomenon recently. A type I diabetic patient of mine (that is, an adult who developed diabetes as a child), Mitch, was experiencing wide swings in blood sugar: low low's and very high high's (300-400 mg/dl). Mitch's magnesium was only marginally low at 2.0 mEq/L. (Ranges for normal magnesium blood levels are usually 1.3–2.1 mEq/L or 0.65–1.05 mmol/L.) Note that Mitch's blood levels fall within "normal." I do not agree with these "normal" ranges. I shoot for 2.1 to 2.4 mEq/L, which I think is the truly normal range.

In addition to eating plenty of raw nuts and green vegetables, Mitch began supplementing magnesium with magnesium citrate, 200 mg twice a day (our preferred supplement form). He reported that the wide swings in blood sugar were nearly eliminated.

Mitch's dramatic benefit is just a great illustration of how magnesium can help control blood sugar metabolism. A type I diabetic is more sensitive to the effects, but anyone with type II (adult) diabetes, metabolic syndrome, or just a slightly high blood sugar could benefit from magnesium supplementation.

There's a number of ways to accomplish getting sufficient magnesium in your daily regimen. Track Your Plaque members, Be sure to read:

Third heart scan a charm

It struck me recently that, for many people, it's not the second but the third heart scan that more commonly shows a reduction in score.

I think this is because many people's reaction to their first heart scan is "This can't be. There's no way my arteries have that much plaque." They then follow a half-hearted program to correct their patterns.

When the second heart scan shows a significantly higher score, that really catches their attention. This is when they finally buckle down and give it their all.

Only the occasional person will, after the first heart scan, seize full control and take their program very seriously. These tend to be highly motivated people.

Don't feel too bad if your second heart scan score shows an increase. Look at it for what it represents: feedback on the adequacy of your program.

Metabolic syndrome--cured

Peter started out at age 59 at 248 lbs, standing 6 ft tall (BMI = 33.6!).

Along with his weight, Peter had the entire panel of phenemena of the so-called "metabolic syndrome", or pre-diabetes:

--Triglycerides 238 mg/dl and associated with extremes of excess VLDL and IDL
--High blood pressure
--Blood sugar 115 mg/dl
--High c-reactive protein
--Small LDL particles 99% of total LDL

Interestingly, Peter's HDL was a surprisingly favorable 58 mg/dl (HDL is usually low in this syndrome). However, when broken down by size, he had nearly zero large, healthy HDL (sometimes called HDL2b). Though total HDL was favorable, most of it was simply ineffective.

Peter eliminated snacks and processed foods, particularly bread; increased his reliance on healthy oils and lean proteins; incorporated soy protein; increased vegetables. He added 30 minutes of a rapid walk on a treadmill every day. He added vitamin D to achieve a blood level of 50 ng/dml. He added a magnesium supplement.

Peter has lost 31 lbs. in the last year. Weight 207 lbs., BMI 28.1 (desirable <25). Blood sugar: 96 mg/dl; triglycerides: 56 mg/dl; HDL 71 mg/dl with 35% in the large fraction; small LDL 45% of total. Not perfect, but a damn site better.

Control of metabolic syndrome is an achievable goal for over 90% of people, just with these simple efforts. We haven't yet had a chance to assess the effect on the progression or regression of Peter's heart scan score, but he has, at the very least, spared himself a future of diabetes and all its complications.

Heart Scan Curiosities #6
















This is a "slice" from a normal heart scan in a 58 year old woman. Heart scan score zero. Look at the lungs, the dark areas left and right of the heart in the center. The lungs are also normal. Black represents normal density, healthy lung tissue. The white streaking is just normal lung blood vessels. This person doesn't smoke.


















This woman smokes a pack of cigarettes a day and has done so for 45 years ("45 pack-years"). She had a surprisingly low heart scan score (at age 64) of only 71, despite the smoking. However, look at this woman's lungs. It's a little tough to make out, since the computer graphics loses some of the resolution. But you can see the near absence of lung tissue on both sides. This is an advanced phase of the destructive lung disease, emphysema, from smoking. Even if she quit smoking today, the destroyed lung tissue never grows back. She literally has huge gaps or holes in her lungs where lung tissue used to be.

Smoking is among the most destructive, terrible things you can do to your body, short of swallowing strychnine or jumping off a building. Stay as far the heck away from cigarettes as you possibly can. If you are exposed to "secondary" smoke, insist that the person never smoke in your presence. It's not the smell that destroys your lungs or causes coronary plaque (though it is indeed foul), it's the actual smoke.

Should you become a vegetarian?

Do you need to become a vegetarian in order to reduce your heart scan score?

No. Plain and simple. We’ve had many non-vegetarians drop their scores.

That said, are there still advantages to following a vegetarian diet, or some variation on the vegetarian theme?

Yes, there are. Let’s put aside the moral or religious arguments in favor of not eating animals—the need to eliminate killing animals for food, elimination of suffering common in modern livestock practices, Kosher considerations, etc. (Not that there aren’t real arguments here. Our focus for this conversation is not, however, the moral dilemma, but the health argument.)

Some of the most unhealthy people I’ve ever met, mostly males, are proud carnivores who boast of their prodigious capacities to eat meat. Unfortunately, it’s hard to tease out the ill-effects of excessive meat eating, since these same men also tend to be substantially overweight, smoke, drink excessively, and fail to get exercise unless their job is physically demanding. You know the type.

What advantages does a vegetarian obtain? A number of studies have suggested that the reduced saturated fat, reduced exposure to parasites, as well as reduced exposure to the antibiotics and hormones now used routinely in livestock-raising practices, do indeed provide benefits to the vegetarian. Thus, vegetarians tend to be substantially thinner, experience less bowel cancer, have less diabetes and heart disease, and live longer.

(If you are interested in reading or seeing more about just how inhumane modern livestock practices are, take a look at the video, "Meet Your Meat" at meat.org. Be sure not to view this after dinner.)

Of course, some of the disadvantages of eating animal products diminish when free-range livestock are eaten, i.e., livestock not raised in the inhumane cramped, filthy conditions of livestock factories, but in the open, grazing or rooting freely. These animals tend to have different fat compositions and taste different.

The advantages of vegetarianism, however, have blurred in recent years, since many so-called vegetarians have failed to maintain the distinction between naturally-occurring foods and processed foods. So, Ritz Crackers, Oreo cookies, whole wheat bread, and Raisin Bran fit into a vegetarian program, but they’re awful for your health. I’ll occasionally meet a self-proclaimed vegetarian who looks every bit as unhealthy as a conventionally eating American, that is, overweight, pre-diabetic person with a developing heart scan score.

So it is not necessary to be vegetarian to reduce your score. You might consider vegetarianism for other reasons, such as moral considerations, or to reduce your risk for cancer. But it is not necessary to drop your heart scan score. A non-processed food diet? Now that's is worth giving serious consideration.
