Jogging does NOT cause heart disease


Periodically, I'll come across a knuckleheaded report like this one from Minneapolis:

Marathon Man’s Heart Damaged by Running?


Of course, the obligatory story about how a cardiologist came to the rescue and "saved his life" with a stent follows. In other words, a stent purportedly saved the life of this vigorous man with no symptoms and high capacity for exercise.

Does vigorous exercise, whether it's marathon running, long-distance biking, or triathlons, cause coronary disease? Should all vigorous athletes run to their doctor to see if they, too, need their lives to be "saved."

Let me tell you what's really going on here. People with the genetic pattern lipoprotein(a), or Lp(a), tend to be slender, intelligent and athletic. For genetic reasons, these people gravitate towards endurance sports like long-distance running. Lp(a) is a high-risk factor for coronary disease. It is the abnormality present in the majority of slender, healthy people who are shocked when they receive a high heart scan score or have a heart attack or receive a stent. (I call Lp(a) "the most aggressive known coronary risk factor that nobody's heard about.")

The association between endurance exercise and heart disease is just that: an association. It does not mean that exercise is causal. Having seen coronary plaque detected with heart scans in many runners, virtually all of whom demonstrated increased Lp(a), I believe that Lp(a) is causal.

Unfortunately, the man in the Minneapolis story, now that his life is "saved," will likely be advised to take a statin drug and follow a low-fat diet . . . you know, the diet that increases Lp(a).

Warning: Your pharmacist may be hazardous to your health

Pharmacists can be very helpful resources when it comes to questions about prescription drugs.

The operant word here is drugs.

What they are most definitely not expert on are nutritional supplements. In fact, a day doesn't pass by without having to dispell one falsehood or another conveyed to a patient about a nutritional supplement by a pharmacist.

Among the more common falsehoods told to patients by pharmacists:

"You have to take Niaspan. Sloniacin doesn't work."

Patent nonsense. A few years back, I was the largest prescriber of Niaspan in Wisconsin. Although I am embarassed to admit it, I also spoke for the company, educating fellow physicians on the value of niacin for correction of lipid disorders.

Then I shifted to Sloniacin due to cost--it costs 1/20th the cost of prescription Niaspan. I examined the pharmacokinetic data (pattern of release in the body), the published literature (e.g., the famous HATS Trial), and have used Sloniacin over 1000 times in patients. In my experience, there is no difference: no difference in efficacy, no difference in safety, no difference in side-effects. There is a BIG difference in price.

Unfortunately, most pharmacists get their information on niacin from the Niaspan representative.


"You shouldn't be taking vitamin D supplements. I have prescription vitamin D here."

What the pharmacist means is that you should replace your vitamin D3, or cholecalciferol--the form recognized as vitamin D by the human body--with the plant form of vitamin D, vitamin D2 or ergocalciferol.

Since when is a plant form of a hormone (vitamin D is a potent hormone, not a vitamin; it was misnamed) better than the human form?

I've previously talked about this issue in a blog post called Vitamin D for the pharmaceutically challenged.

The notion that D2 is somehow superior to the real thing, D3, is absurd. I use D3 only in my practice and have checked blood levels thousands of times. As long as the D3 comes as a gelcap, drops, or powder in a capsule, it works great, yielding predictable and substantial increases in blood levels of 25-hydroxy vitamin D. If it comes as prescription D2 (or over-the-counter D2), I have seen many failures: no increase in blood levels of vitamin D or meager increases.

Prescription status is no guarantee of effectiveness.


"Why do you need iodine? You already get enough from food."

The NHANES data over the last 25 years argue otherwise: Iodine deficiency is growing, particularly as people are avoiding iodized salt and the iodine content of processed foods is diminishing. The explosion in goiters in my office also suggest this is no longer a settled issue.

On the positive side, it is exceptionally easy to remedy with an inexpensive iodine supplement. That is, until the pharmacist intervenes and injects his bit of nutritional mis-information.


I'm not bashing pharmacists. In fact, Track Your Plaque's own Dr. BG has a pharmacy background, and she is an absolute genius with nutritonal supplements. But she is a rare exception to the rule: Most pharmacists know virtually nothing about nutritional supplements. You might as well ask your hairdresser.

"Healthy" people are the most iodine deficient

Ironically, the healthiest people are the most likely to be deficient in iodine.

Why?

Healthy people tend to:

--Avoid iodized salt because of public health advice to limit sodium
--Use sea salt to obtain minerals like magnesium--but sea salt contains little iodine
--Limit meat--Carnivores obtain more iodine than vegetarians or vegans. In one study, up to 80% of vegans were iodine-deficient (Krajcovicova-Kudlackova M et al 2003).
--Exercise--Substantial amounts of iodine are lost through sweating. In a study of high school soccer players, 38.5% were severely iodine deficient, compared to 2% of sedentary students (Mao IF et al 2001).


That is indeed what I am seeing in my office, as well: The healthiest, most attentive to healthy eating, and most physically active are the ones showing up with small goiters (enlarged thyroid glands) and increased TSH and low free T4 levels.

Why am I checking thyroid and talking about iodine? Because even the smallest degree of thyroid dysfunction can double, triple, or quadruple your risk for cardiovascular events. See the posts Is normal TSH too high? and Thyroid perspective update.

What kind of iodine do you take?

The results of the latest Heart Scan Blog poll are in.

204 respondents answered the question:


Do you take an iodine supplement?

The responses:

Yes, I take Iodoral, Lugol's, or SSKI
26 (12%)

Yes, I take potassium or sodium iodide
19 (9%)

Yes, I take kelp tablets or powder
64 (31%)

No, I rely on generous use of iodized salt
23 (11%)

No, I don't supplement iodine at all
66 (32%)

Isn't iodine something you put on cuts and scratches?
6 (2%)


I am heartened by the number of respondents taking iodine in some form. After all, iodine is an essential trace mineral. Without it and health suffers, often dramatically.

However, I am concerned by the percentage of people who don't supplement iodine at all: 32%. Interestingly, this is approximately the proportion of people who come to my office who also do not supplement iodine who are now showing goiters, or enlarged thyroid glands due to iodine deficiency. Goiters lead to hypothyroidism (low thyroid hormone levels), followed by hyperactive nodules, not to mention undesirable effects like weight gain, fatigue, hair loss, constipation, intolerance to cold, higher LDL cholesterol and triglycerides, and heart disease.

11% of respondents report using lots of iodized salt. This may or may not be sufficient to provide enough iodine to prevent goiter and allow normal thyroid function. The success of this strategy depends to a great extent on how often salt is purchased. Salt that sits on the shelf for more than a month is devoid of iodine, given iodine's volatility.

I am also favorably impressed by the number of people who take "serious" iodine supplements like Lugol's solution, Iodoral, or SSKI. Of course, people who read The Heart Scan Blog tend to be an unusually informed, healthy population. The 12% of people in the poll who take these forms of iodine does clearly not mean that 12% of the general population also takes them. But 12% is more than I would have predicted.

On the Track Your Plaque website, we are awaiting an interview with iodine expert, Dr. Lyn Patrick. I'm hoping for some juicy insights.

And you thought gasoline was expensive

In 1995, the Palmaz coronary stent was introduced, the brainchild of Drs. Julio Palmaz and Richard Schatz. Medical device manufacturer, Johnson & Johnson, priced the device at $2500 per stent.

Let's put this into perspective: At just 0.05 grams per 15 millimeter stent, that put the price of the common stainless steel used to manufacture the stent at $22,650,000 per pound.

Only after several competing stents finally made it to market did J&J reduce its price to its bargain price of $1200, or $10,872,000 per pound. And to think that most of us were shocked to find out that the U.S. military paid $200 for a hammer.

Since 1995, a competitive market for stents has developed, pushing prices down. Now, you can purchase a brand-new coronary stent for as little as $4,000,000 per pound.

Medical device manufacturers have been guilty of a degree of greed that would make many Wall Street bankers blush. That's why I call medical devices "the industry of infinite markups."

"Hey buddy, wanna buy some exorphins?"

Dr. Christine Zioudrou and colleagues at the National Institutes of Mental Health got this conversation going back in 1979 with their paper, Opioid peptides derived from food proteins: The exorphins.

Exorphins are exogenously-derived peptides (i.e., short amino acid sequences obtained from outside the body) that exert morphine-like properties. Mimicking the digestive process that occurs in the gastrointestinal tract using the gastric enzyme, pepsin, and hydrochloric acid (stomach acid), Zioudrou et al isolated peptides from wheat gluten with morphine-like activity. They followed this research path because of the apparent association of wheat and mental illness.

In the bioassays used, wheat-derived exorphins competed successfully with the endogenous opiate, met-enkephalin. Interestingly, casein-derived (i.e., casein milk protein) exorphins were also identified that also displayed opiate-binding activity, though less powerfully. The morphine-like activity was also blocked by the drug, naloxone (the same stuff given to people exposed to morphine overdose).

Among the many devastating effects of celiac disease , the immune disease that develops from wheat gluten exposure, are mental and emotional effects, such as anxiety, fatigue, mental "fog," depression, bipolar illness, and schizophrenia, that disappear with removal of gluten. Many parents of autistic children also advocate wheat-free diets for similar reasons.

Among the many wonderful comments posted on the last Heart Scan Blog post, "I can't do it," was Anne's:

I am not the Anne in your post, but I was addicted to wheat. It was my favorite food. I lived on and for breads. Then I discovered I was gluten sensitive and I did go through a withdrawal of about 4 days. After 4 days I noticed my health problems were disappearing. Depression, brain fog and joint pain are 3 of the many symptoms that disappeared. That was 6 yrs ago.

Tell Anne that I had dreams about bread in the beginning - they will pass. Now the donuts, breads, cookies and cakes in the stores and at work don't even look good. In fact, I don't like the smell of bread anymore. It takes time, but the cravings do pass.



Combine wheat"s exorphin-driven addictive potential with its flagrant blood sugar-increasing properties, and you have a formula that:

1) makes you fat
2) increases likelihood of diabetes, and
3) makes you want to keep on doing it.

Reminds me of nicotine.

My personal view: I have absolutely no remaining doubt that wheat products have no place in the human diet. Not only does the research provide a plausible basis for its adverse health effects, but having asked hundreds of people to remove it from their habits has yielded consistent and remarkable health benefits. Just read the reader comments here and here.

"I can't do it"

Anne sat across from me, bent over and sobbing.

"I can't do it. I just can't do it! I cut out the breads and pasta for two days, then I start dreaming about it!

"And my husband is no help. He knows I'm trying to get off the wheat. But then he brings home a bunch of Danish or something. He knows I can't help myself!"

Having asked hundreds of people to completely remove wheat from their diet, I witness 30% of them go through such emotional and physical turmoil, not uncommonly to the point of tears. For about 10-20% of people who try, it is as hard as quitting cigarettes.

Make no mistake about it: For many people, wheat is addictive. It meets all the criteria for an addictive product: People crave it, consuming it creates a desire for more, lacking it triggers a withdrawal phenomenon. If wheat were illegal, there would surely be an active underground trafficking illicit bagels and pretzels.

Withdrawal consists of fatigue and mental fogginess that usually lasts 5-7 days. Just like quitting smoking, wheat withdrawal is harmless but no less profound in severity.

People who lack an addictive relationship with wheat usually have no idea what I'm talking about. To them, wheat is simply a grain, no different than oats.

But wheat addicts immediately know who they are. They are the ones who can't resist the warm dinner rolls served at the Italian restaurant, need to include something made of wheat at every meal, and crave it every 2 hours (matching the cycle of blood sugar peaks and valleys, the "valley" triggering the craving). When they stop the flow of immediately-released glucose that comes from wheat (with blood sugar peaks that occur higher and faster than table sugar), irresistible cravings kick in. Then watch out: They'll bite your hand off if you reach for that roll before they do.

Break the cycle and the body is confused: Where's the sugar? The body is accustomed to receiving a constant flow of easily-digested sugars.

Once the constant influx of sugars ceases, it takes 5-7 days for metabolism to shift towards fat mobilization as a source of energy. But along with fat mobilization comes a shrinking tummy, reducing the characteristic wheat belly.

If you try to quit smoking, you've got "crutches" like nicotine patches and gum, Zyban, Chantix, hypnosis, and group therapy sessions. If you try and quit wheat, what have you got? Nothing, to my knowledge. Nothing but sheer will power to divorce yourself from this enormously destructive, diabetes-causing, small LDL-increasing, inflammation-provoking, and addictive substance.

Spontaneous combustion, vampires, and goitrogens

What do the following have in common:

Lima beans
Flaxseed
Broccoli
Cabbage
Kale
Soy
Millet
Sorghum?

They are all classified as goitrogens, or foods that have been shown to trigger goiter, or thyroid gland enlargement. Most of them do this either by blocking iodine uptake in the thyroid gland or by blocking the enzyme, thyroid peroxidase. This effect can lead to reduction in thyroid hormone output by the thyroid gland, which then triggers increased thyroid stimulating hormone (TSH) by the pituitary; increased TSH acts as a growth factor on the thyroid, thus goiter.

Add to this list of goitrogens the flavonoid, quercertin, found in abundance in red wine, grapes, apples, capers, tomatoes, cherries, raspberries, teas, and onions. Most of us obtain around 30 mg per day from our diet. Quercetin, often touted as a healthy flavonoid alongside resveratrol (e.g., Yang JY et al 2008), has been shown to be associated with reduced risk for heart disease and cancer. Many people even take quercetin as a nutritional supplement.

Quercetin has also been identified as a goitrogen (Giuliani C et al 2008).

What to make of all this?

Most of these observations have been made in in vitro ("test tube") preparations or in mice. Rabbits who consume a cabbage-only diet can develop goiter.

How about humans? The few trials conducted in humans have shown little or no effect. In most instances, the adverse effects of goitrogens have been eliminated with supplemental iodine. In other words, goitrogens seem to exert their ill thyroid effects when iodine deficiency is present. Restore iodine . . . no more goitrogens (with rare exceptions).

Should we as humans adopt a diet that avoids apples, grapes, tomatoes, red wine, tea, onions, soy etc. on the small chance that we will develop goiter?

I believe that we should avoid these common food-sourced goitrogens with as much enthusiasm as we should be worried about spontaneous combustion of humans or the appearance of vampires on our front porches. We are as likely to suffer low thyroid activity from quercetin or other "goitrogens" as we are to experience the "mitochondrial explosions" that are purported to set innocent people afire.

Magnesium and you-Part II

Blood magnesium levels are a poor barometer for true body (intracellular) magnesium.

Only 1% of the body’s magnesium is in the blood, the remaining 99% stored in various body tissues, particularly bone and muscle. If blood magnesium is low, cellular magnesium levels are indeed low—very low.

If blood magnesium is normal, cellular or tissue levels of magnesium may still be low. Unfortunately, tissue magnesium levels are not easy to obtain in living, breathing humans. In all practicality, a blood magnesium test only helps if it’s low, while normal levels don’t necessarily mean anything and may provide false reassurance.

Short of performing a biopsy to measure tissue magnesium levels, several signs provide a tip-off that magnesium may be low:

• Heart arrhythmias—Having any sort of heart rhythm disorder should cause you to question whether magnesium levels in your body are adequate, since low magnesium levels trigger abnormal heart rhythms. In fact, in the hospital we give intravenous magnesium to quiet down abnormal rhythms.
• Low potassium— Low magnesium commonly accompanies low potassium. Potassium is another electrolyte depleted by diuretic use and is commonly deficient in many conditions (e.g., excessive alcohol use, hypertension, loss from malabsorption or diarrhea). Like magnesium, potassium may not be fully replenished by modern diets.
• Muscle cramps— Magnesium regulates muscle contraction. Leg cramps, or “charlie-horses”, painful vise-like cramps in calves, fingers, or other muscles, are a common symptom of magnesium deficiency. (Leg cramps that occur with physical activity, such as walking, are usually due to atherosclerotic blockages in the leg or abdominal arteries, not low magnesium.)
• Migraine headaches—Reflective of magnesium’s role in regulating blood vessel tone, low magnesium can trigger vascular spasm in the blood vessels of the brain. In some emergency rooms, they will actually administer intravenous magnesium to break a migraine.
• Metabolic syndrome—Magnesium plays a fundamental role in regulating insulin responses. Metabolic syndrome (low HDL, high triglycerides, small LDL, high blood pressure, increased blood sugar, excessive abdominal fat, etc.) is triggered by insulin responses gone awry and is clearly linked to low magnesium levels.

The absence of any of these tell-tale signs does not necessarily mean that tissue levels of magnesium are normal.

Then how do you really know? There really is no easy, available method to gauge body magnesium. As a practical solution, we therefore have aimed for maintaining serum levels of >2.1 mg/dl or RBC magnesium (a surrogate for tissue levels) of >6.0 mg/dl. (Going too high is not good either, so occasional monitoring really helps. However, I've only seen this once in a psychotic woman who drank ungodly amounts of magnesium-containing antacids for no apparent reason; she almost ended up on a respirator due to respiratory suppression by the magnesium level of 11 mg/dl!)

In all practicality, because of magnesium’s crucial role in health, its widespread deficiency in Americans, and the growing depletion of magnesium in water, supplemental magnesium is necessary for nearly everyone to ensure healthy levels.

More on magnesium to come.

Lethal Lipids II

I call the combination of low HDL, small LDL, and lipoprotein(a) "lethal lipids," since the trio is an exceptionally potent predictor for heart disease. Uncorrected, the combination is a virtual guarantee of heart disease.

Ed is a perfect example of someone who came to my office recently with this pattern. His starting values:

HDL: 34 mg/dl

Small LDL: 78% of total LDL
NMR: Small LDL 1655 nmol/L; total LDL particle number 2122 nmol/L)

Lipoprotein(a): 205 nmol/L



The atherogenicity, or plaque-causing potential, of this pattern was reflected in Ed's heart scan score of 2133.

You can readily see that, of this combination, only HDL cholesterol would be adequately identified through conventional lipid testing. Small LDL and lipoprotein(a) need to be specifically measured via lipoprotein testing.

And, contrary to the drug industry's "statin drugs for everybody" motto, this pattern, while improved with statin therapy, is not shut off.

Specific correction of each abnormality is required. For instance, niacin addresses all three: increases HDL, reduces small LDL, and (usually) reduces lipoprotein(a). A standard low-fat diet makes this pattern worse by reducing HDL, increasing small LDL, and (usually) increasing lipoprotein(a).

When meat is not just meat


The edgy nutrition advocate, Mike Adams, over at NewsTarget.com came up with this scary photo tour of a processed meat product from Oscar Mayer: Mystery Meat Macrophotography: A NewsTarget PhotoTour by Mike Adams







Along with increasingly close-up photographs of this meat-product, Adams lists the ingredients in Oscar Mayer's Cotto Salami:


Beef hearts
Pork
Water
Corn syrup
Beef

Contains less than 2% of:
Salt
Sodium lactate
Flavor
Sodium phosphates
Sodium diacetate
Sodium erythorbate
Dextrose
Sodium nitrite
Soy lecithin
Potassium phosphate
Potassium chloride
Sugar


As I reconsider the role of saturated fat in diet, given the startlingly insightful discussion by Gary Taubes of Good Calories, Bad Calories, I am reminded that not all meat is meat, not all saturated fat sources are equal.

I am concerned in particular about sodium nitrite content, a color-fixer added to cured meats that caused a stir in the 1970s when data suggesting a carcinogenic effect surfaced. The public's effort to remove sodium nitrite from the food supply was vigorously opposed by the meat council and it remains in cured meats like sausage, hot dogs, and processed meats like Cotto Salami. A 2006 meta-analysis (combined analysis of studies) of 63 studies did indeed suggest that sodium nitrite was related to increased risk of gastric cancer. This argument is plausible from animal models of cancer risk, as 40 animal models have likewise suggested the same carcinogenic association.

Also, fructose? This is most likely added for sweetness. Recall that fructose heightens appetite and raises triglycerides substantially.

I personally have a natural aversion to meat. I don't like the taste, the look, smell, and the thought of what the animal went through to make it to the supermarket. But, considered from the cold, carnivorous viewpoint of the question, "Is meat okay to eat?", among the issues to consider is whether the meat has been cured or processed, and does that process include addition of sodium nitrite.

Cotto Salami and similar products are not, of course, what carnivorous humans in the wild ate. This is a processed, modified product created from factory farm animals raised in cramped conditions and fed corn and other cheap, available foods. It is not created from free-ranging animals wandering their pastures or pens, eating diets nature intended. This results in modified fat composition, not to mention hormones and antibiotics added. These are not listed on the ingredients. Wild meat does not contain fructose or color-fixers, either.

So don't mistake "meat" in your grocery store for meat. It might look and smell the same--until you look a little closer.

Don't lament no OTC mevacor

After Merck's third go at FDA approval for over-the-counter (OTC) status for its statin cholesterol drug, Mevacor (lovastatin), the FDA advisory board suggested that its request be denied. They expressed concern that too many people would not understand how the drugs would be used and that misuse would be common.

Similar sentiments were echoed by Dr. Sidney Wolfe, director of the Health Research Group at Public Citizen; the American Medical Association (though the AMA always fights anything that threatens to erode physician control over health); and the de facto spokesman for cardiologists, Dr. Steven Nissen of the Cleveland Clinic.

Although I am a supporter for tools and legislation that yield greater self-empowerment in health care to the public, there is no need to lament the failed OTC status for Mevacor. For one, Merck had no plans to reduce the price on its OTC preparation. For many people, this would have meant an increase in cost, since health insurers would surely not cover a non-prescription agent.

Second, OTC status sends the implicit message that cholesterol is the most common cause of heart disease; it is not. (Small LDL particles are the number one cause, a pattern only partially addressed by any statin drug and a pattern largely responsible for the failure of statin drugs to "cure" heart disease despite pharmaceutical manufacturer's attempts to increase doses to take up any slack in effect.)

Thirdly, you can achieve the same effect--no, a superior effect--by incorporating several simple strategies into your life. These strategies are superior to Mevacor because they do more than just reduce LDL cholesterol. You can achieve similar LDL-reducing effect to Mevacor, 20 mg, just by adding:

--2 tablespoons oat bran or ground flaxseed per day (choose flaxseed if you have sugar problems or small LDL; flaxseed contains no digestible sugars, only protein and fiber)
--Raw almonds or walnuts--at least a handful, though more is fine and will not make you fat. (It's nuts like party mixes, mixed nuts roasted in unhealthy oils, and honey-roasted nuts that make us fat, not raw.)
--Soy protein sources--probably the weakest effect of all foods listed, but a contributor that can be obtained in a variety of forms, such as tofu, soy protein powders, and soy milk.
--Other foods that reduce LDL include pectin sources (e.g., citrus rind), flavonoids (e.g., green tea); stanol esters found in butter substitute Benecol (recall that sterol-containing products like Take Control and the flood of new products on the market like HeartWise orange juice might have potential for allowing sterol esters to enter the blood, so I do NOT recommend them); and, of course, niacin.

Many of these strategies also reduce small LDL, raise HDL, reduce triglycerides, and reduce blood sugar, effects that go beyond that achieved with Mevacor. Of course, a combination strategy is not as easy as popping one pill a day, it's better for you.

I will certainly not shed any tears for Merck and its relentless efforts to gain a stronger foothold in the "transform conditions into diseases" marketing strategy, the same strategy that classifies shyness, toe fungus, and sadness into medical conditions necessitating medication. While I do generally support efforts to increase public access to strategies that increase their health care power, this one was not necessarily all good.

Damage control

Medical device manufacturer, Cordis, is launching a new marketing program to promote its Cypher drug-coated stent. You can view the details at www.CypherUSA.com , including the slick TV commercial that HeartHawk posted a blog about.

The campaign opens with:

When you open up your heart, you open up your life.

Lives hampered by angina. By shortness of breath. By restricted blood flow. These lives are changing. Because of a state-of-the-art advancement. One that can have a huge impact on arteries around your heart. The CYPHER® Stent. It can open up your arteries. Increase flow of blood and oxygen. And change your restricted life. To an active life worth living. Your new life is...

Life Wide Open


Direct-to-consumer drug advertising has been around for a few years. While it has increased awareness of drugs and the "conditions" they are supposed to treat, it has also highlighted the aggressive profit-motive of the drug industry. This is not health care for the needy and sick, but health care for profit.

So now we're beginning to see the emergence of direct-to-consumer (DTC) advertising for medical devices. There was also a brief, though unsuccessful, foray into DTC advertising for implantable defibrillators, of all things, by Medtronic a couple of years ago, also.

What is the purpose of Cordis' marketing effort? Is it to educate and inform the public who might unknowingly receive non-drug coated stents and be deprived of the restenosis-inhibiting advantage of a drug-coated device? Is it meant to right a systematic wrong, a failure of cardiologists to insert the technologically, biologically, and ethically superior coated stents?

I find that doubtful. A more likely motive is damage control. With some of the (both deserved and undeserved) negative press the drug-coated stents have received lately, Cordis, eager to protect their $20 billion (annual revenues, 2006) medical device franchise, came up with this DTC strategy. After viewing the smiling faces of people , elated because of their "wide open" arteries and lives, Cordis hopes to see people going to their doctors insisting on the stent that is "opening millions of lives," since, "when your arteries narrow, so does your life."

Cool, trendy, liberating. That's the message they wish to deliver. Cool music, beautiful people, flashy high-tech images. Who wouldn't want a Cypher stent?

Beyond damage control, it's a familiar marketing theme: You're slender, glamorous, and sexy if you drink Coke, you're a caring mother if you feed your children Jif peanut butter, you're health conscious and smart if you eat Total cereal . . . you're cool and know what you want from life if you insist on a Cypher stent.

I don't object to advertising. It's part of the capitalistic economic system. It drives awareness and grows businesses. I do get concerned when advertising is so slick and effective that the people who are not properly armed with information can be duped into thinking that they need something that they don't really need.

Or, for which there are powerful, viable alternatives. Even hear about "prevent the disease in the first place?"

Low expectations

The Framingham Risk Calculator is a standard method used by many physicians to predict risk for heart attack or death from heart disease over a 10-year period. Low-risk is defined as <10% risk of heart attack or cardiac death over 10 years; high-risk is defined as 20% or more over 10 years; intermediate-risk is in between.

Let's put it to the test:

Amy is a 53-year old businesswoman. She is 5 ft 4 inches, weighs 150 lbs. Her father had a heart attack in his early 50s followed by the usual list of hospital procedures including bypass surgery at age 60.

What is Amy's risk for heart attack or death from heart disease over the next 10 years? If we enter her data into the Framingham risk calculator, the following result is returned:

Information about your risk score:
Age: 53
Gender: female
Total Cholesterol: 198 mg/dL
HDL Cholesterol: 74 mg/dL
Smoker: No
Systolic Blood Pressure: 120 mm/Hg
On medication for HBP: No
Risk Score: 1% Means 1 of 100 people with this level of risk will have a heart attack in the next 10 years.


So, according to the Framingham calculation, Amy has <1% risk for heart attack or death from heart disease over the next 10 years. Most primary care physicians would, at most, prescribe a statin drug and talk about a reduction in saturated fat.

Thankfully, Amy didn't fall for that bit of conventional mis-information. She instead got a CT heart scan, principally because of her father's history. Her score: 117. At age 53, this put her into 90th percentile, in the worst 10% of scores for women in her age group (50-55). By heart scan criteria, her risk for heart attack is probably more like 4-5% per year, or approximately 40-50% over the next 10 years.

Let's do just a bit more math. If Amy hadn't known about her heart scan score and no preventive action was taken, the expected progression of her heart scan scores would likely be:

Start: 117
Year 1: 152
Year 2: 198
Year 3: 257
Year 4: 335
Year 5: 436
Year 6: 567
Year 7: 737
Year 8: 958
Year 9: 1245
Year 10: 1618

In fact, given Amy's starting heart scan score of 117, it is highly unlikely that she survives the next 10 years without heart attack or a fatal heart event. Yet the Framingham risk calculator puts Amy's risk at less than 1%. Could anything be more wrong?

The folly of the Framingham calculator was highlighted by a recent publication from the large Multi-Ethnic Study of Atherosclerosis (MESA), in which 3600 women (45-84 years), all of whom fell into the "low-risk" category by the Framingham calculator--just like Amy--were tracked over approximately 3 3/4 years. This study generated several observations:

1) 30% of the "low-risk" women had positive heart scan scores.
2) 5% of the "low-risk" women had scores of 300 or greater (very significant for a woman). 8.6% of these women experienced a cardiovascular event like heart attack or death over the period. Women with a heart scan score of 300 or greater had a 22-fold greater event risk compared to women with zero heart scan scores.
3) Women with heart scan scores of 1 to 299 had a cardiovascular event risk of approximately 5-fold greater risk over the period.


Across the U.S., 90% of women younger than 70 years old fall into the Framingham "low-risk" category. Yet this fiction is accepted as the prevailing standard, along with LDL and total cholesterol, for determination of risk in women and men.

In my view, using the Framingham risk calculator is a misguided, misleading path, one that will mis-classify a substantial number of women who could otherwise be spared from heart attack and catastrophe.

By the way, Amy is also the Track Your Plaque program record holder (by percentage drop), with a 63% drop in heart scan score over a 15 month period.

Niacin vs. low-carb weight loss

Niacin:

--Raises HDL and shifts HDL towards the healthier large (HDL2b) subclass.
--Reduces total LDL.
--Reduces small LDL particles.
--Reduces triglycerides and triglyceride-containing particles like VLDL and IDL (intermediate-density lipoprotein).
--Reduces fibrinogen.
--Reduces inflammatory responses.


Weight loss achieved through a low-carbohydrate (read "wheat-free") diet:

--Raises HDL and shifts HDL towards the healthier large (HDL2b) subclass.
--Reduces total LDL.
--Reduces small LDL particles.
--Reduces triglycerides and triglyceride-containing particles like VLDL and IDL (intermediate-density lipoprotein).
--Reduces fibrinogen.
--Reduces inflammatory responses.


Curious, isn't it? Niacin achieves virtually the same effect as weight loss achieved through a low-carbohydrate diet, particularly if free of wheat products. The only major difference is that niacin also reduces lipoprotein(a), though even that distinction shrinks if monounsaturated fat sources like almonds are included in a low-carbohydrate program.

So which should you do first if you have any of the above patterns? Well, it's a question of 1) severity, 2) how carbohydrate-rich your starting diet is, 3) how much weight you could stand to lose, and 4) how urgent your program is (determined largely by your heart scan score).

Niacin can also be very helpful if you've taken full advantage of weight loss through a carbohydrate-restricted program, yet still retain some of the abnormal lipoprotein patterns that could continue to grow coronary plaque. For instance, if HDL cholesterol rises from 28 to 40 mg/dl by eliminating wheat and reducing carbohydrates and losing weight, niacin could raise HDL to 50 mg/dl or higher.

As much as I love and use niacin for its broad array of plaque-controlling effects, a low-carbohydrate, wheat-free diet can achieve many of the same effects. Use this strategy to full advantage.

Explosive plaque growth

Every once in a while, we will see someone experience more-than-expected rate of coronary plaque growth, a sudden jump in heart scan scores. I'm talking about increases in score of 50%, even 100%, sometimes despite favorable lipid and lipoprotein patterns.

It's not always easy to pin this phenomenon down, since we often detect it after a year or more on a repeat heart scan. It would be wonderfully insightful to perform heart scans more frequently and track plaque growth more precisely, but of course, radiation exposure is the most important limiting factor, as is cost.

So this list is, admittedly, speculative. It is based on observation, on presumptive associations between events and heart scan scores. But, judging from what we do confidently know about coronary atherosclerotic plaque, I think these observations make physiologic sense.

These are the sorts of increases in heart scan score that can scare the heck out of you, silent yet explosive growth of coronary atherosclerotic plaque that can grow with no warning whatsoever.

Factors which I have observed to possibly be responsible for explosive plaque growth include:

--Overwhelming tragedy such as death of a loved one, financial ruin, divorce. One of my early and catastrophic failures was a young man in his early 40s who, in the space of just a few months, suffered the loss of his mother, a brother, and his mother-in-law, while working a high-stress job. His heart scan score doubled from around 100 to 200 in one year, despite perfect lipoproteins. He had a heart attack shortly after the second score, despite a normal stress test just months earlier. (Pessimism is tragedy's weak cousin, but one that still holds power to corrupt our otherwise best efforts at plaque reversal.)

--Substantial weight gain. In the early years of the Track Your Plaque program, before it was even called "Track Your Plaque," I witnessed a man more than double his score from 1100 to 2400 in 18 months just by allowing himself to gain 40 lbs. (I don't know what became of him. His life apparently suffered other disasters, as well, and we lost track of him.)

--Poorly-controlled diabetes. High blood sugars out of control have yielded explosive growth.

--Kidney disease--However, I am uncertain of how much this overlaps with a deficiency of vitamin D's active form, 1,25-OH-vitamin D3, the form that is often deficient in people with dysfunctional kidneys.

--An inflammatory disease that is out of control, e.g., rheumatoid arthritis.

--This is very speculative, but I've witnessed explosive growth after vaccine administration that yielded strange viral-like symptoms. In this one instance, the man was getting heart scans (on his own) every three to six months and described a severe illness following a vaccine administered in preparation for travel out of the U.S.

--Unrecognized low thyroid function--i.e., hypothyroidism. This is easily corrected with thyroid hormone replacement.


These factors can also be relative and they can be overcome. Look at our current Track Your Plaque reversal record-holder: a 53-year old woman who dropped her heart scan score an amazing 63% despite the loss of a loved one during the 15 months of her program. Despite an overwhelming tragedy, she overcame the potential adverse effects and set a record, probably a record for the entire world.

Dr. Cannell on "How much vitamin D?"

In his most recent Vitamin D Council Newsletter (reprinted in its entirety below, minus clickable links, as Dr. Cannell apparently lost his webmaster and this issue of the newsletter is therefore not posted on the Vitamin D Council website; if you would like to either donate money to the Vitamin D Council or pitch in with help with his website, go to www.vitamindcouncil.com), Dr. John Cannell once again enlightens us with some new insights into vitamin D and its enormous role in health. In this issue, he discusses the role of vitamin D in people diagnosed with cancer (treatment, not prevention).

While cancer is not our focus on the Heart Scan Blog, Dr. Cannell's always insightful comments provide some helpful thoughts for our management of vitamin D doses and blood levels.

Dr. Cannell cites a recent study from vitamin D research expert, Dr. Bruce Hollis:

In the first study of its kind, Professor Bruce Hollis of the Medical University of South Carolina gave all of us something to think about. He asked and answered a simple question: How much vitamin D do you have to take to normalize the metabolism of vitamin D?

Remember, unlike other steroid hormones, vitamin D has very unusual metabolism in most modern humans, called first-order, mass action, kinetics. All this means is that the more vitamin D you take, the higher the 25(OH)D level in your blood, and the higher the 25(OH)D level in your blood, the higher the levels of activated vitamin D in your tissues. No other steroid hormone in the body behaves like this. Think about it: would you like your estrogen level to be dependent on how much cholesterol you ate? Or your cortisol level? (I'd ask the same about testosterone levels but I know men well enough not to ask.) No, the body must tightly regulate powerful steroid hormones through substrate inhibition, that is, if an enzyme turns A into B, when the body has enough B, B inhibits the enzyme and so limits its own production.

Not so with vitamin D, at least at modern human vitamin D levels. Professor Reinhold Vieth was the first to write about this and Vieth's Chapter 61 in Feldman, Pike, and Glorieux's wonderful textbook, Vitamin D (Elsevier, 2005, second edition), is a great reason to buy the textbook or have your library do so. (I'm glad to see Amazon is out of stock of the new ones (someone must be reading about vitamin D) but you can still buy used editions.)

Why would the kinetics of vitamin D be different from all other steroids? Maybe they are not, Hollis reasoned, like Vieth before him. Maybe vitamin D levels are so low in modern humans that its metabolic system is on full blast all the time in an attempt to give the body all the vitamin D metabolites it craves. So Hollis asked, Is vitamin D's metabolism different in populations in the upper end of 25(OH)D levels (a population of sun-exposed people and a group of women prescribed 7,000 IU per day)? Note, the Hollis study is free on Medline, you can download the entire paper on the right hand of the PubMed page below.

Hollis BW, et al. Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-634.

If you look at the two graphs, Figures 1 and 2 of Hollis' paper, you find vitamin D's kinetics can be normalized, made just like all other steroid hormones in the body, but you have to get enough sunshine or take enough vitamin D to get your 25(OH)D level above 50 ng/ml, and 60 ng/ml would be better. Then your body starts to store cholecalciferol in the body without much further increase in 25(OH)D levels. The reaction becomes saturable. This is a remarkable discovery and it implies levels of 30 and 40 ng/ml are usually not sufficient. It also implies actual vitamin D levels (cholecalciferol levels), not just 25(OH)D levels, may be useful in diagnosing and treating deficiency. Note, that not all of the sun-exposed individuals or women prescribed 7,000 IU/day achieved such levels. That's because the sun-exposed individuals were tested after an Hawaiian winter and because prescribing and taking are two different things.

In answer to the question, "How much vitamin D should someone with cancer take?," Dr. Cannell advises:
"Take enough to get your 25(OH)D level above 60 ng/ml, summer and winter." In doing so, you will have normalized the kinetics of vitamin D and stored the parent compound, cholecalciferol, in your tissues. In the absence of sunshine, you need to take about 1,000 IU/day per 30 pounds of body weight to do this. A 150 pound cancer patient may need to take 5,000 IU per day, a 210 pound cancer patient about 7,000 IU per day, all this in the absence of sunlight.

Dr. Cannell, no stranger to the resisitance among many practicing physicians unaware of the expanding and robust literature on vitamin D, advises people with cancer that:
In the end, if you have cancer and your physician won't do a risk/benefit analysis, do it yourself. The risk side of that equation is easy. Both Quest Diagnostics and Lab-Corp, the two largest reference labs in the USA, report the upper limit of 25(OH)D normal is 100 ng/ml and toxic is above 150 ng/ml, so 60 ng/ml is well below both. The reason levels up to 100 ng/ml are published normals is because there is no credible evidence in the literature that levels of 100 ng/ml do any harm and because sun worshipers often have such levels. (If you don't believe me, go to the beach in the summer for one month, sunbath every day for 30 minutes on each side in your bathing suit, and go home and have a 25(OH)D level.) By getting your level above 60 ng/ml, all you are doing is getting your levels into the mid to upper range of laboratory reference normals. Little or no risk.



For readers wishing to read the entire text of Dr. Cannell's newsletter, it is reprinted below:

The Vitamin D Newsletter
January, 2008


The January newsletter is coming early as I will be out of touch for awhile. If you remember, the last newsletter was on preventing cancer, not treating it. Below is a sampling of the tragic emails the last newsletter generated:


"Dr. Cannell, I was just diagnosed with breast cancer, how much vitamin D should I take?"

"My mother has colon cancer, how much vitamin D should she take?"

"I've had prostate cancer for four years, is there any reason to think vitamin D would help?"

"Dr. Cannell, my son has leukemia, should I give him vitamin D?"


It's one thing to talk about evidence vitamin D may prevent cancer but something quite different to discuss evidence vitamin D might help treat cancer. I used to think the answers to all the above questions were the same. Like anyone else, people with cancer should be screened for vitamin D deficiency and be treated if deficiency is present. Simple. However, it's not that simple. The real questions are, What are reasonable 25-hydroxy-vitamin D [25(OH)D] levels for someone with a life-threatening cancer? How much vitamin D do they need to take to obtain such levels? Is there any evidence, of any kind, that vitamin D will help treat cancer? The risk/benefit analysis of taking vitamin D is quite different if you are in perfect health than if your life, or your child's life, is on the line.

Remember, unlike cancer prevention, not one human randomized controlled trial exists showing vitamin D has a treatment effect on cancer. By treatment effect, I mean prolongs the lives of cancer patients. However, as I cited in my last newsletter, Dr. Philippe Autier of the International Agency for Research on Cancer, and Dr. Sara Gandini of the European Institute of Oncology, performed a meta-analysis of 14 randomized controlled trials showing even low doses of vitamin D extend life but they looked at all-cause mortality, not just cancer (Arch Intern Med. 2007;167(16):1730-1737). However, some epidemiological studies indirectly address the treatment issue and are quite remarkable. The first are a series of discoveries by Professor Johan Moan, Department of Physics at the University of Oslo, with Dr. Alina Porojnicu as the lead author on most of the papers.

Moan J, et al. Colon cancer: Prognosis for different latitudes, age groups and seasons in Norway. J Photochem Photobiol B. 2007 Sep 19

Porojnicu AC, et al. Changes in risk of death from breast cancer with season and latitude: sun exposure and breast cancer survival in Norway. Breast Cancer Res Treat. 2007 May;102(3):323-8.

Porojnicu A, et al. Season of diagnosis is a predictor of cancer survival. Sun-induced vitamin D may be involved: a possible role of sun-induced Vitamin D. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):675-8.

Porojnicu AC, et al. Seasonal and geographical variations in lung cancer prognosis in Norway. Does Vitamin D from the sun play a role? Lung Cancer. 2007 Mar;55(3):263-70.

What Professor Moan's group discovered, repeatedly, is quite simple, whether it be cancer of the breast, colon, prostate, lung, or a lymphoma. You live longer if your cancer is diagnosed in the summer. And it is not just Moan's group who has found this. A huge English study recently confirmed Moan's discovery.

Lim HS, et al. Cancer survival is dependent on season of diagnosis and sunlight exposure. Int J Cancer. 2006 Oct 1;119(7):1530-6.

What do these studies mean? Something about summer has a treatment effect on cancer. Whatever it is, you live longer if you are diagnosed in the summer but die sooner if you are diagnosed in the winter. What could it be about summer? Exercise? Fresh air? Melatonin? Sunlight? Pretty girls? Remember, these patients already had cancer. Whatever it is about summer, it is not a preventative effect that Professor Moan discovered, it is a treatment effect. Something about summer prolongs the life of cancer patients.

Dr. Ying Zhou, a research fellow, working with Professor David Christiani at the Harvard School of Public Health, went one step further. The stuffy Harvard researchers assumed summer worked its magic, not by pretty girls, but by summer sunlight making vitamin D. So they looked at total vitamin D input, from both sun and diet, to see if high vitamin D input improved the survival of cancer patients. Yes, indeed, remarkably. They found that early stage lung cancer patients with the highest vitamin D input (from summer season and high intake from diet) lived almost three times longer than patients with the lowest input (winter season and low intake from diet). Three times longer is a huge treatment effect, a treatment effect that most conventional cancer treatment methods would die for.

Zhou W, Vitamin D is associated with improved survival in early-stage non-small cell lung cancer patients. Cancer Epidemiol Biomarkers Prev. 2005 Oct;14(10):2303-9.

And that's not all, Marianne Berwick and her colleagues, at the New Mexico Cancer Institute, found malignant melanoma patients with evidence of continued sun exposure had a 60% mortality reduction compared to patients who did not. That implies a robust treatment effect from sunlight.

Berwick M, et al. Sun exposure and mortality from melanoma. J Natl Cancer Inst. 2005 Feb 2;97(3):195-9.

I will not list the thousands of animal studies that indicate vitamin D has a treatment effect on cancer as almost all of them studied activated vitamin D or its analogs, drugs that bypass normal regulatory mechanisms, cannot get autocrine quantities of the hormone into the cell, and that often cause hypercalcemia. However, Michael Holick's group found that simple vitamin D deficiency made cancers grow faster in mice. That is, vitamin D has a cancer treatment effect in vitamin D deficient mice. Professor Gary Schwartz, at Wake Forest, recently reviewed the reasons to think that vitamin D may have a treatment effect in cancer.

Tangpricha V, et al. Vitamin D deficiency enhances the growth of MC-26 colon cancer xenografts in Balb/c mice. J Nutr. 2005 Oct;135(10):2350-4.

Schwartz GG, Skinner HG. Vitamin D status and cancer: new insights. Curr Opin Clin Nutr Metab Care. 2007 Jan;10(1):6-11.

Finally, one human interventional study exists. In 2005, in an open trial, Professor Reinhold Vieth and his colleagues found just 2,000 IU of vitamin D per day had a positive effect on PSA levels in men with prostate cancer.

Woo TC, et al. Pilot study: potential role of vitamin D (Cholecalciferol) in patients with PSA relapse after definitive therapy. Nutr Cancer. 2005;51(1):32-6.

So we come back to the crucial question. If you have cancer, how much vitamin D should you take, or, more precisely, what 25(OH)D level should you maintain? We don't know. You can correctly say that definitive studies have not been done and, incorrectly, conclude physicians treating cancer patients should do nothing. I say incorrectly because standards of medical practice have always demanded that doctors make reasonable decisions based on what is currently known, doing a risk/benefit analysis along the way to decide what is best for their patients based on what is known today. If a patient has a potentially fatal cancer, the doctor cannot dismiss a relatively benign potential treatment modality just because definitive studies have not been done, and passively watch his patient die. Standards of care require doctors consider what is known now, using information currently available, perform a risk/benefit analysis, and then act in the best interest of their patient.

Luckily, such doctors recently obtained some guidance. In the first study of its kind, Professor Bruce Hollis of the Medical University of South Carolina gave all of us something to think about. He asked and answered a simple question: How much vitamin D do you have to take to normalize the metabolism of vitamin D?

Remember, unlike other steroid hormones, vitamin D has very unusual metabolism in most modern humans, called first-order, mass action, kinetics. All this means is that the more vitamin D you take, the higher the 25(OH)D level in your blood, and the higher the 25(OH)D level in your blood, the higher the levels of activated vitamin D in your tissues. No other steroid hormone in the body behaves like this. Think about it, would you like your estrogen level to be dependent on how much cholesterol you ate? Or your cortisol level? (I'd ask the same about testosterone levels but I know men well enough not to ask.) No, the body must tightly regulate powerful steroid hormones through substrate inhibition, that is, if an enzyme turns A into B, when the body has enough B, B inhibits the enzyme and so limits its own production.

Not so with vitamin D, at least at modern human vitamin D levels. Professor Reinhold Vieth was the first to write about this and Vieth's Chapter 61 in Feldman, Pike, and Glorieux's wonderful textbook, Vitamin D (Elsevier, 2005, second edition), is a great reason to buy the textbook or have your library do so. [ I'm glad to see Amazon is out of stock of the new ones (someone must be reading about vitamin D) but you can still buy used editions.)

Why would the kinetics of vitamin D be different from all other steroids? Maybe they are not, Hollis reasoned, like Vieth before him. Maybe vitamin D levels are so low in modern humans that its metabolic system is on full blast all the time in an attempt to give the body all the vitamin D metabolites it craves. So Hollis asked, Is vitamin D's metabolism different in populations in the upper end of 25(OH)D levels (a population of sun-exposed people and a group of women prescribed 7,000 IU per day)? Note, the Hollis study is free on Medline, you can download the entire paper on the right hand of the PubMed page below.

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

If you look at the two graphs, Figures 1 and 2 of Hollis' paper, you find vitamin D's kinetics can be normalized, made just like all other steroid hormones in the body, but you have to get enough sunshine or take enough vitamin D to get your 25(OH)D level above 50 ng/ml, and 60 ng/ml would be better. Then your body starts to store cholecalciferol in the body without much further increase in 25(OH)D levels. The reaction becomes saturable. This is a remarkable discovery and it implies levels of 30 and 40 ng/ml are usually not sufficient. It also implies actual vitamin D levels (cholecalciferol levels), not just 25(OH)D levels, may be useful in diagnosing and treating deficiency. Note, that not all of the sun-exposed individuals or women prescribed 7,000 IU/day achieved such levels. That's because the sun-exposed individuals were tested after an Hawaiian winter and because prescribing and taking are two different things.

So my answer to "How much should I take if I have cancer?" is "Take enough to get your 25(OH)D level above 60 ng/ml, summer and winter." In doing so, you will have normalized the kinetics of vitamin D and stored the parent compound, cholecalciferol, in your tissues. In the absence of sunshine, you need to take about 1,000 IU/day per 30 pounds of body weight to do this. A 150 pound cancer patient may need to take 5,000 IU per day, a 210 pound cancer patient about 7,000 IU per day, all this in the absence of sunlight. And this may not be enough; cancer patients may use it up faster (increased metabolic clearance) and children may do the same due to their young and vital enzymes. Or you may need less, because you get more sun than you think, more from your diet, or because you are taking a modern medicine that interferes with the metabolism of vitamin D. An even easier way to do it is go to a sun tanning booth every day and obtain and keep a dark, full-body, tan. Then you don't have to worry about blood levels but I'd get one anyway, just to be sure it was above 60 ng/ml.

Given what Hollis discovered, given the well-known potent anti-cancer properties of activated vitamin D, given epidemiological evidence that summer extends the life of cancer patients, given a meta-analysis of randomized controlled trials showed that vitamin D prolongs life, given animal data that simple vitamin D has a treatment effect on cancer, and given a patient with a life-threatening cancer, what would a reasonable physician do? Simply let their patient die while muttering something about the lack of randomized controlled trials?

No, they would simply check a 25(OH)D level every month and advise cancer patients to take enough vitamin D or frequent sun tanning parlors enough to keep their level above 60 ng/ml. Toxicity does not start until levels reach 150 ng/ml but if you take more than 2,000 IU per day have your doctor order a blood calcium every month or two along with the 25(OH)D. Both you and he will feel better and because if you have cancer, you are probably taking lots of other drugs and little is known about how modern drugs interact with vitamin D metabolism. By getting your level above 60 ng/ml, all you are doing is getting your level to where most lifeguards' levels are at the end of summer, to levels our ancestors had when they lived in the sun, to levels regular users of sun-tan parlors levels achieve, and most importantly, to levels where vitamin D's pharmacokinetics are normalized.

In the end, if you have cancer and your physician won't do a risk/benefit analysis, do it yourself. The risk side of that equation is easy. Both Quest Diagnostics and Lab-Corp, the two largest reference labs in the USA, report the upper limit of 25(OH)D normal is 100 ng/ml and toxic is above 150 ng/ml, so 60 ng/ml is well below both. The reason levels up to 100 ng/ml are published normals is because there is no credible evidence in the literature that levels of 100 ng/ml do any harm and because sun worshipers often have such levels. (If you don't believe me, go to the beach in the summer for one month, sunbath every day for 30 minutes on each side in your bathing suit, and go home and have a 25(OH)D level.) By getting your level above 60 ng/ml, all you are doing is getting your levels into the mid to upper range of laboratory reference normals. Little or no risk.

What are the potential benefits? It probably depends on a number of things. Did your cancer cells retain the enzyme that activates vitamin D? Many do. Did your cancer cells retain the vitamin D receptor? Many do. If your cancer cells get more substrate [25(OH)D], will that substrate induce the cancer cells to make more vitamin D receptors or more of the activating enzyme? Some cancer cells do both. In practical terms, vitamin D is theoretically more likely to help your cancer the earlier you start taking it. However, no one knows. Certainly there is no reason, other than bad medicine, for cancer patients to die vitamin D deficient. Unfortunately, most do.

Plant AS, Tisman G. Frequency of combined deficiencies of vitamin D and holotranscobalamin in cancer patients. Nutr Cancer. 2006;56(2):143-8.

It is very important that readers understand I am not suggesting vitamin D cures cancer or that it replace standard cancer treatment. Oncologists perform miracles every day. Do what they say. The only exception is vitamin D. If your oncologist tells you not to take vitamin D, ask him three questions. 1) How do you convert ng/mls to nmol/Ls? How many IU in a nonogram? 3) How do you spell "cholecalciferol?" If he doesn't know how to measure it, weigh it, or spell it, chances are he doesn't know much about it.

All of the epidemiological and animal studies in the literature suggest cancer patients will prolong their lives if they take vitamin D. I can't find any studies that indicate otherwise. However, none of the suggestive studies are randomized controlled interventional trials; they are all epidemiological or animal studies, or, in the case of Vieth's, an open human study. However, if you have cancer, or your child does, do you want to wait the decades it will take for the American Cancer Society to fund randomized controlled trials using the proper dose of vitamin D? Chances are you, or your child, will not be around to see the results.

End-stage vitamin D deficiency

Let me paint a picture:

A 78-year old woman, tired and bent. She's lost an inch and a half of her original height because of collapse of several vertebra in her spine over the years, leaving her with a "dowager's hump," a stooped position that many older women assume with advanced osteoporosis. It's also left her with chronic back pain.


(Image courtesy of National Library of Medicine)

This poor woman also has arthritis in her knees, hips, and spine. All three locations add to her pain.

She also has hypertension, a high blood sugar approaching diabetes, and distortions of cholesterol values, including a low HDL and high triglycerides.

Look inside: On a simple x-ray, we see that the bones of her body are unusually transparent, with just a thin rim of bone at the outer edges, depleted of calcium. Weight-bearing bones like the spine, hips, and knees have eroded and collapsed.

On an echocardiogram of her heart (ultrasound), she has dense calcium surrounding her mitral valve ("mitral anular calcium"), a finding that rarely impairs the valve itself but is a marker for heightened potential for heart attack and other adverse events. Her aortic valve, another of the four heart valves, is also loaded with calcium. In the aortic valve, unlike the mitral valve, the collection of calcium makes the valve struggle to open, causing a murmur. The valve is rigid and can barely open to less than half of its original opening width.

If a heart scan were performed, we'd see the coronary calcification, along with calcification of the aorta, and the mitral and aortic valves.

Obviously, it's not a pretty picture. It is, however, a typical snapshot of an average 78-year old woman, or any other elderly man or woman, for that matter.

This collection of arthritis, osteoporosis, coronary and valve calcification, high blood pressure, abnormal cholesterol patterns, and pain is not unusual by any stretch. Perhaps you even recognize someone you know in this description. Perhaps it's you.

Look at this list again. Does it seem familiar? I'd say that the common factor that ties these seemingly unrelated conditions together is chronic and severe deficiency of vitamin D. Vitamin D deficiency leads to arthritis, osteoporosis, coronary and valve calcification, high blood pressure, abnormal cholesterol patterns, and pain.

Should we go so far as to proclaim that aging, or at least many of the undesirable phenomena of aging, are really just manifestations of vitamin D deficiency? I would propose that much of aging is really deficiency of vitamin D, chronic and severe, in its end stages.

My colleagues might propose a 30- or 40-year long randomized trial, one designed to test whether vitamin D or placebo makes any difference.

Can you wait?

"Instant" reversal with fasting?

Here's a fascinating e-mail we received recently. It came from a man in Hawaii who dropped his heart scan score a modest amount, but did it in two months using fasting. He also has the advantage of access to the Holistica Hawaii scan center with our friend, Dr. Roger White. His experience is so fascinating that we asked for his permission to reprint his story which he did enthusiastically.

So here is Don's story:


I am a 61 year old male with a history of heart disease in my family. My maternal grandfather, for instance, died at age 39 of a
heart attack and my mother died of a stroke. There are other instances in my family as well.

I, personally, before going to Holistica had had three heart procedures; one radio catheter ablation for WPW Syndrome, and two radio catheter ablations for atrial fibrilations. After suffering with WPW for over 30 years and A-Fibs for about a year, those issues seem to be behind me fortunately.

Three or four months back, however, I was suffering from shortness of breath and slight chest pains when doing the uphill part of a 5 mile walk that I do almost every day. My wife had had a coronary heart scan several years back at Holistica so that's how I knew about it.

I had a scan done on October 4th this year. The scan did show fairly
advanced plaque build up; my total coronary plague burden was
312.9. The day following the scan I felt absolutely terrible; lightheaded, weak, much like feeling you were at death's door.

I had read a book a number of years back about therapeutic fasting
(water only) called "Fasting and Eating for Health" by Dr. Joel
Furhman.


According to his book, one on the areas where he consistently has dramatic and quick results with fasting is with reducing arterial plaque. Based on how badly I was feeling at the time, I decided to start an immediate fast. Within just the first 24 hours, the relief was dramatic and amazing. I continued the water only fast for 3 weeks.

Yesterday, December 1st I went in for another cardio scan instead of the coronary angiogram that I had previously been scheduled for. I could tell they were a little confused why I was doing that but went ahead and did another coronary EBT scan.

When I went in for the doctor consultation, Dr. McGriff said, "OK, exactly what is it you've done since last time." In less than two months, my coronary plaque burden had dropped to 296.2. That's a 6% reduction in less than 2 months. Had I gone back in for the second scan right after my 3 week fast then it probably would have a 6%
reduction in less than a month.

Frankly, based on how good I've been feeling (I'm even thinking of
getting back into jogging instead of walking), I was surprised it was
only 6%. Based on the common experience, however, that it sometimes
takes a year or two to just stabilize your plaque increase, much less
actually start losing it, the doctor was truly startled and
surprised. He said he had never seen such a sudden reduction as that
before!

We are still going to proceed with the coronary angiogram and I
intend to apply what I find in your book but I thought you might be interested in these results since I've never heard or read of anyone actually measuring the effectiveness of a fast with before and after EBT Scans.

I admire your direction and work focusing on prevention instead of catastrophic management like most doctors. Dr. Fuhrman is very much the same with the greatest attention on prevention so if you haven't heard of his book you might be interested. Especially interesting regarding this particular issue is Chapter 5 entitled, "The Road Back to a Healthy Heart-the Natural Way."

I can personally verify everything he has said about the fasting procedure itself from start to finish. I consider his book the Bible about fasting. As I mentioned, given your similar direction in medicine, I thought I would bring my personal experience on the matter to your attention for your consideration. Maybe in a future edition of your book, you might want to include some information on fasting.

Anyhow, I hope you will find this helpful. Any other questions,
don't hesitate to e-mail back. Please keep up your good work and
thanks for what your doing!

Yours truly,

Isn't that great?

Now, in all honesty, a change of 6% could conceivably be within the margin of error for heart scanning. (Although several studies from a number of years ago suggested that variation in heart scan scoring was about 10%, sometimes more, in my experience, on EBT devices like the one Don used, variation is <5% at this score range.) Genuine regression would probably be better documented by yet another scan down the road. If the trend is consistent, then it is probably real.

Nonetheless, Don's story may support we've been saying for some time: Fasting is a rapid method to gain control over plaque--but I didn't know it might be that quick! Perhaps Don is a living example of what I've called "instant" heart disease reversal.

Don is potentially off to a good start. But, unless he can periodically repeat his fast, he will still have to engage in a program that allows continuing control over coronary plaque in between fasts. Also, fasting cannot address issues like vitamin D deficiency, lipoprotein(a), and any residual lipid/lipoprotein issues. But I am continually impressed with the power of fasting to "jump start" a program of heart disease reversal.

It would be a fascinating study to perform, with serial heart scans within brief periods of weeks or months to gauge rapid response. However, we need to keep in mind that as wonderful as heart scans are, they do involve modest radiation exposure.

It might be interesting in future to add a fasting "arm" to the virtual clinical trial. That might yield some great insights.

Study review: yet another Lipitor study

This continues a series I've begun recently that discusses studies that have emerged over the past 10 years relevant to heart scan scoring and reversal of coronary atherosclerotic plaque.

The St. Francis Heart Study from St. Francis Hospital, Roslyn, New York, was released in 2005. This was yet another study that set out to determine whether Lipitor exerted a slowing effect on coronary calcium scores. This time, Lipitor (atorvastatin), 20 mg per day, was combined with vitamin C 1 g daily, and vitamin E (alpha-tocopherol) 1,000 U daily, vs. placebo. A total of 1,005 asymptomatic men and women, age 50 to 70 years, with coronary calcium scores 80th percentile or higher for age and gender
participated in the study.

After four years, heart scan scores in the placebo group increased 73%, compared to 81% in the treatment group. Statistically, the cocktail of drug, vitamins C and E had no effect on heart scan scores.

Other findings included:

--Participants experiencing heart attack and other events during the study showed greater progression of scores than those not experiencing heart attack: score increase of 256 vs. increase of 120.

--While treatment did not reduce the number of heart attacks and events overall, participants with starting heart scan scores >400 did show a benefit: 8.7% with events on treatment (20 of 229) vs. 15.0% with placebo (36 of 240).

(Note what is missing from the treatment regimen: efforts to raise HDL (starting average HDL 51 mg/dl); reduce triglycerides (starting average 140 mg/dl); identify those whose LDL was false elevated by lipoprotein(a); omega-3 fatty acids from fish oil; correction of other factors like vitamin D deficiency.)


Are we pretty in agreement that just taking Lipitor and following an American Heart Association low-fat diet is an unsatisfactory answer to gain control over coronary plaque growth? No slowing of heart scan score growth seen in the St. Francis Heart Study and similar studies is consistent with the 25-30% reductions in heart attack witnessed in large clinical trials. Yes, heart attack and related events are reduced, but not eliminated--not even close.

And when you think about it, it should come as no surprise that the simple strategy studied in the St. Francis Heart Study failed to completely control plaque growth. Lipitor and statin drugs exert no effect on small LDL particles, barely raise HDL cholesterol at all, and have no effect on Lp(a), factors that increase heart scan scores substantially.

Though these discussions have frightened some people because of the suggestion that increasing heart scan scores are inevitable and unavoidable, they shouldn't. It really should not be at all shocking to learn that taking one drug all by itself should cure coronary heart disease.

Instead, findings like those of the St. Francis study should cause us to ask: What could be done better? How can we better impact on heart scan scores and how can we further reduce heart attack, particularly in people with higher heart scan scores?

My answer has been the Track Your Plaque program, a comprehensive effort to 1) address all causes of coronary plaque, and then 2) correct all the causes.
