The Track Your Plaque guide to getting grotesquely overweight

15. August 2006 William Davis (0)

If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

Your heart scan is just a "false positive"

15. August 2006 William Davis (0)

I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

What's better than a heart scan?

13. August 2006 William Davis (0)

Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Lipids are snapshots in time; heart scans are cumulative

12. August 2006 William Davis (0)

Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

11. August 2006 William Davis (0)

The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:

Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)

Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

What role DHEA?

9. August 2006 William Davis (2)

DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.

In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.

The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

Brainwashed!

9. August 2006 William Davis (0)

At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist.

"What hospital do you work at?" he asked.

This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time.

This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period.

Tense families, drama, high-tech...It all takes place in the hospital.

Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan.

We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.

In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes.

The Fanatic Cook: A fabulous Blog about food and nutrition

7. August 2006 William Davis (0)

I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:

The Fanatic Cook at http://fanaticcook.blogspot.com/

I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)

Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.

There's also oodles of recipes, all for the taking.

Eggs: Good, bad, or indifferent?

5. August 2006 William Davis (3)

Eggs have been in the center of the cholesterol controversy almost from the very start.

The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)

A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events.

This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously.

Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn.

A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)

Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate.

We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain.

The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.

Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out.

Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

Diabetes is Track Your Plaque's Kryptonite!

3. August 2006 William Davis (0)

If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes.

I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes.

Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss.

Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range.

Roy's repeat heart scan showed a score of 482--a tripling of his original score.

Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth.

Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know.

The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".)

Vitamin D and autism

17. August 2007 William Davis (1)

This has nothing to do with coronary plaque reversal, nor directly with the Track Your Plaque program, but I found Dr. John Cannell's discussion about the possible relationship between vitamin D and autism so compelling that I thought I just had to pass it on.

So, below are Dr. Cannell's latest thoughts. He takes some criticisms along with praise. I think we owe him a lot for continuing to doggedly promote the benefits of vitamin D.

Vitamin D Newsletter

August, 2007

Dear Dr. Cannell:

I saw an article from a Toronto newspaper about autism and vitamin D. I am currently searching for a vitamin D specialist in the Washington D.C. area to perform a medical work up on my daughter to look for vitamin D-related disorders. The reason I am in search of a vitamin D specialist is that I believe I have stumbled upon a complex relationship in my daughter involving her foot pain, vitamin D, and her autism.

In April 2006, a few weeks after my 3-year-old profoundly autistic daughter began refusing her daily PediaSure drink, she began having excruciating foot spasms lasting from 10-30 minutes at a time, several times a week. She would throw herself on the floor, curl her toes, slam her heels against the floor, and rub the tops of her feet against the carpet, all while screaming the entire time. These were horrible for her to endure, and horrible for my wife and myself to watch. This went on for a year.

From what I read, the symptom was perhaps like foot spasms associated with carpopedal syndrome or tetany. But her blood work did not support that at all. Calcium level was normal (10.2 mg/dL); 25-Hydroxy-vitamin D low (23.5 ng/ml); 1,25 dihydroxy-vitamin D normal (24.7). Despite some vitamin D deficiency, I was assured by medical professionals that nothing supported a vitamin D cause of these particular spasms, so vitamin D was dismissed. Because her calcium level was normal, they told me she did not have tetany, and vitamin D could not be the cause of the pain.

All medical consultants were stymied. I made another research effort and found a 2003 article on WebMD that stated vitamin D has been found to have some link to basic, unexplained muscle and bone pain. By chance, vitamin D was the next supplement we had at home to begin giving my daughter to treat her autism. So, in April 2007 we began giving my 4 year-old profoundly autistic daughter Vitamin D supplements. Her foot spasms which had plagued her for a year diminished within days and disappeared within three weeks. She has not had a spasm in over two months.

In addition, we noted clear improvements in her autistic condition which appear to be from the vitamin D supplements. Eye contact went from zero to fantastic. Her vocalizations increased markedly (still only babbling; she remains completely nonverbal). She appears even happier than previously (she has always been a somewhat happy child). (Please note that my wife and I have tried many dietary supplements over the past 1.5 years guided by a doctor and dietician who both specialize in autism. We honestly state that this is the only thing that has ever had a positive effect on my daughter. We have seen nothing else work.)

My daughter and vitamin D have a complicated relationship. By all counts, looking at her lab work and general condition, vitamin D should have played no role in those excruciating foot fits. And yet it is apparently exactly what is involved in them. And, my wife and I believe at the same time her autistic condition has improved from the vitamin D. The foot fits and her autism appear linked; it was not just a coincidence that this autistic child has those mysterious foot spasms, and the link appears to be vitamin D.

And so I wonder if this is just the tip of the iceberg, if perhaps there is more to know about my child's relationship with vitamin D and what that might mean for her autism. Does she have a specific vitamin D-related disorder? If so, might direct treatment of it also improve her autism further? These are the questions I would like to pose to a vitamin D specialist who could perform a medical work up on my daughter. Please let me know if you know of anyone in the Northern Virginia/Washington DC area. Also, where is the best place to get vitamin D? Thank you for your time.

Sincerely,
Paul, Washington, D.C.

Dear Paul:

I know of no such specialist in the Washington area, indeed no vitamin D/autism expert exists in the world. As far as a specific "vitamin D disorder," linking her spasms, autism, and vitamin D, the world's English language medical literature contains no description of such a disorder. From your daughter's case, it sounds as if PediaSure was her only regular source of vitamin D. If so, her spasms began two weeks after stopping the small amount of vitamin D contained in PediaSure. The spasms continued for a year, ending a few days after you started giving her vitamin D again, this time in the form of a supplement. Several weeks after restarting vitamin D, both you and your wife noticed an improvement in her autism. To my knowledge, this "case report" - your daughter's - is the first ever published.

As no medical literature has ever been published on any of this, all you can do is give her enough vitamin D to get her 25-hydroxy-vitamin D, known as 25(OH)D, into high normal ranges and then wait and hope. Vitamin D's extraordinary mass-action pharmacology implies that simply providing more substrate ([25(OH)D] will help children with low enzyme activity produce more activated vitamin D (calcitriol) in their brains. The vitamin D theory of autism is not simply that vitamin D deficiency in gestation or early childhood causes the disorder. Instead, the theory holds that a quantitative or qualitative abnormality exists in the enzyme system that activates vitamin D.

It could as simple as the normal variation in the enzyme, an enzyme whose activity would vary in a normal or Gaussian distribution, much like height. Some people are tall, some are short, most are in the middle. The same may be true of the enzyme that forms activated vitamin D (calcitriol), some children have a lot of enzyme and some only a little; most are in the middle. As the substrate [25(OH)D] the enzyme metabolizes fell over the last 20 years with sun-avoidance, more and more children on the low end of the enzyme curve are effected by marginally low 25(OH)D levels, explaining both its genetic basis and exploding incidence.

At this point, all your daughter needs is a physician willing to periodically measure her 25(OH)D. Then you can safely supplement your daughter with doses higher than the current Upper Limit for children (2,000 IU/day). You did not tell me your daughter's weight but, assuming she weighs about 30 pounds, even without 25(OH)D blood tests, you can safely give her 50 mcg/day which is 2,000 IU per day. In fact, the U.S. government says this dose is safe for children over the age of one. Life Extension Foundation sells 250 of the 1,000 IU capsules for about ten bucks with powdered vitamin D inside. The powder is tasteless and dissolves easily in juice. Bio Tech Pharmacal, of Fayetteville, Arkansas, told me they were going to be making a 1,000 IU capsule. Or you can get 1,000 IU capsules in a pharmacy or at Costco and crush them. A Canadian firm is now making vitamin D liquid, called Ddrops, with 1,000 IU per drop, but their mail order web site is not yet easily accessed. Beware of cod liver oil; do not use it because vitamin A inhibits the actions of activated vitamin D, and due to the potential for low-grade vitamin A toxicity.

Remember, more and more researchers now believe autism is a progressive, inflammatory, disorder. That is, the inflammation probably progressively destroys brain tissue as the child ages. As I said in my recent paper, I think there is a chance that vitamin D may have a treatment effect in young autistic children if given in adequate doses, due to its anti-inflammatory properties, and its ability to upregulate glutathione, the master antioxidant that also chelates (binds) and then helps excrete heavy metals like mercury. Unfortunately, I see no way, even if the vitamin D/autism theory turns out to be true, that vitamin D can regenerate brain tissue. However, if it stops the inflammation, and cell death, the brain could then begin to develop and learn. These are big ifs. However, you have nothing to lose by trying, the worst that will happen is that it will not help and vitamin D will be added to the long list of false-hope treatments.

Actually, there is a worse possibility. Say the parents of a three-year-old autistic child decide today that vitamin D is nonsense, another false hope, and that I'm a quack. They decide not to give vitamin D supplement their autistic child, who is probably - like your child - vitamin D deficient. Then, it turns out five years from now that scientific evidence shows vitamin D does indeed help. By that time, the child will be eight and will have suffered additional, irreparable, brain damage. In my mind, that is more tragic than another false hope.

Dear Dr. Cannell:

After that article appeared in the Toronto paper, I started my four-year-old son on 1,000 IU of vitamin D two weeks ago. So far the only thing I noticed is that after about ten days, he didn't seem so miserable. The thing that has always broken my heart is that look of sadness and suffering on his face. After about two weeks of vitamin D, I noticed he seemed less miserable. I wouldn't say he looks happy now but that look of misery seems to be gone. Will it come back? I'm not sure I can take it if it comes back. What else might happen? Also, last summer we noticed he seemed to get better, but then he got worse in the fall. We never thought about it until we read about vitamin D.

Susan, Toronto, Canada

Dear Susan:

I don't know. I think all parents have had their heart pierced by that look at one time or another. I would advise increasing the dose to 2,000 IU per day, making sure it is cholecalciferol and not ergocalciferol, and having your doctor order a 25(OH)D every two months to see if he needs higher doses. You want to get his blood level up to between 50 ng/ml and 80 ng/ml (In many countries outside of the USA, that would be reported as between 125 and 200 nmol/L.) and keep it there, summer and winter, and that may take more than 2,000 IU/day in the winter. If vitamin D has a treatment effect, it will take many months to see its full effect. As you noted, if the theory is correct, autistic children who spend time outdoors in the summer should show some seasonal improvements - if they don't wear sunblock and they expose enough of their skin to generate significant amounts of vitamin D.

Dear Dr. Cannell:

I resent you calling autism a tragedy. My son is not a tragedy and I'm glad he was born and is in our lives. He is our joy. Autism is not a tragedy.

Emma, London, England.

Dear Emma:

I'm glad he is your joy and I believe you. I'm new to the autism field and was not aware how much thought and speech control exists in the discussion of the disease. Nevertheless, I have a few politically incorrect questions. If autism is a joy, I assume you would like other parents to have an autistic child? If autism is such a joy, why is there a huge industry forming to prevent and treat it? At the risk of sounding insensitive - apparently one of the most serious charges leveled in the autism debate - autism is a tragedy. As I pointed out in my paper, research shows that having an autistic child, puts the family under more emotional stress than having a child with a fatal illness.

Dear Dr. Cannell:

Who are you to write an article on autism? You didn't even publish it in a medical journal. You are not with a university. You have not published very much. You have no expertise on autism. No autism experts support your theory. There is no evidence to support the theory. Shouldn't you leave this to experts before you give parents more false hopes?

Mary, Trenton, New Jersey.

Dear Mary:

You are right, I am a nobody; just ask my ex-wife. In the Toronto Globe, I explained why I have not yet submitted the paper. As far as giving false hopes, I've thought about that charge. Right now, regardless of what advocacy groups say, autism is rather hopeless. That is, no treatment, including vitamin D, has been shown to materially affect the clinical course of autism. As a psychiatrist, my observation is that people would rather live with a false hope than with no hope.

Furthermore, if autistic children began taking vitamin D, the worse that can happen is that a period of false hope will followed by dashed hopes and then parents will be back to hopelessness. In the meantime, they will have made their child vitamin D sufficient. Vitamin D deficiency is a serious problem in childhood.

The Telegraph, Why is Vitamin D So Vital?

As far as the theory having no support from experts, Dr. Richard Mills, research director of the National Autistic Society in England, was quoted in the Telegraph article on the autism/vitamin D theory: "There has been speculation in the past about autism being more common in high-latitude countries that get less sunlight and a tie-up with rickets has been suggested - observations which support the theory."

Finally, you said there is no evidence to support the theory. I assume you meant there is no proof. The first statement is absolutely false, the second absolutely true. As I detailed in my paper, there is a lot of evidence to support the theory. In fact, if anyone can come up with an autism fact, that the theory cannot explain, I'd like to know about it. Even the announcement of a link between television viewing and autism supports the theory. Furthermore, the TV/autism link is actually evidence of a treatment effect. That is, if autistic children who play outside in the sunshine more - watching less TV - have less severe illness, it may be due to the Sun-God, who bestows her precious gift of calcitriol into the brains of children playing outside in her sunlight but not into the brains of children watching TV inside in the darkness.
Natl Bur Econ Res Bull Aging Health. 2007 Winter;(18):2-3.

As far as proof the theory is true, there is, of course, none. In medicine, proof means randomized controlled human trials, the gold standard for proof. However, proof is the last step, not the first. First comes evidence, then comes a theory, then comes researchers disproving those theories. It works that way. Sometimes we never get to the last step, proof. For example, please point me to a single randomized controlled human trial proving cigarette smoking is dangerous? Instead, the convincing evidence of smoking's dangerousness lies in epidemiological studies, not randomized controlled trials. Proof, or disproof, of the autism vitamin D theory will take years, years during which young autistic brains will continue to suffer irreparable damage. Perhaps vitamin D' powerful anti-inflammatory actions will help prevent that damage, perhaps not.

It's something of a Pascal's wager, betting on vitamin D instead of the existence of God, risking your child's brain instead of eternal damnation. "If you believe vitamin D helps autism and turn out to be incorrect, you have lost nothing -- but if you don't believe in vitamin D and turn out to be incorrect, your child will suffer irreparable brain damage."

Michael Pollan Podcast

15. August 2007 William Davis (3)

I just found this great podcast of an April, 2006 National Public Radio (NPR) interview with Omnivore's Dilemma author, Michael Pollan:

Author Michael Pollan: 'The Omnivore's Dilemma'

available at http://www.npr.org/templates/story/story.php?storyId=5342514

The Science Friday segment is a great encapsulation of all the fascinating spins this wonderfully insightful author has on human eating habits and the developing distortions of food choices, much magnified by the food manufacturing industry.

One of my favorite comments from Pollan: "The USDA should be called "The Department of Corn," referring to the ubiquitous dissemination of corn products into livestock and human foods that has increasingly led to the enormous health problems we're all facing in 2007.

Are you addicted to fructose?

13. August 2007 William Davis (1)

Try a little experiment:

Side by side, try a yogurt made with fructose or high fructose corn syrup as one of the first ingredients on the label along with a yogurt made without fructose.

Yoplait and Dannon brands, for instance, fit the bill for fructose. Several brands do not use fructose products. Many of these are the unflavored or unsweetened versions. You may therefore have to add some blueberries, strawberries, or some other fruit for some flavor. ( I doubt that you would add high fructose corn syrup.) Add nuts, seeds, flaxseed, or oat bran to either.

Many people who do this will notice a peculiar effect: The fructose or high fructose corn syrup containing product is, to most, delicious. It also triggers a desire for more. You can't have just one--you've got to have another, or you've got to eat something else.

The non-fructose containing product is more likely to generate satiety, a feeling that you've had enough.

If you experience this effect, the solution is simple: avoid fructose and high fructose corn syrup. I believe that the most worrisome health effect of fructose is this hunger-increasing aspect, difficult to document, perhaps impossible to measure, but a great boon to the food industry who practice an "eat more" philosophy to increase revenues year after year.

Perhaps you will also see weight drop (since you will be more satisfied), see triglycerides drop (since fructose raises triglycerides), and maybe obtain all the downstream benefits of reduced triglycerides (higher HDL, less small LDL, less VLDL, more rapid clearance of post-prandial lipoproteins).

Most people who follow this idea gain better control over appetite, lose weight, and do better in health, including in their Track Your Plaque program.

Chicken Little

11. August 2007 William Davis (1)

Clinical studies can be designed in a number of ways. The ease and cost of these studies differ dramatically, as does the confidence of the findings.

The most confident way to design a clinical study is to tell neither the participants nor the investigator(s) what treatment is being offered, then to administer treatment or placebo. Neither the people doing the research nor the participants know what they are receiving. Of course, there needs to be some way to find out what was given at the end of the study in order to analyze the outcome.

This is called a “double-blind, placebo-controlled” clinical study. While not perfect since it tends to examine a treatment phenomenon in isolation (e.g., the effects of a single drug in a select group of people), it is the best sort of study design that is most likely to yield confident results, both negative and positive. This sort of design is followed, for instance, for most prescription drugs.

There are pitfalls in such studies, of course, and some have made headlines lately. For instance, beyond tending to examine single conditions in a select group of participants, a double-blind, placebo-controlled study can also fail to uncover rare effects. If a study contains 5000 participants, for instance, but a rare complication develops in 1 person out of 20,000, then it’s unlikely such an ill-effect will be observed until larger numbers of people are exposed to the agent.

Another pitfall (though not so much of study design, but of human greed) is that study outcomes that are not favorable can be suppressed by simply failing to publish the results. This has undoubtedly happened numerous times over the years. For this reason, a registry has been created for all human clinical trials as a means to enforce publication of outcomes, both favorable and unfavorable.

Despite its weaknesses, the double-blind, placebo-controlled study design remains the most confident way to show whether or not some treatment does indeed yield some effect. It is less prone to bias from either the participant or the investigator. Human nature being what it is, we tend to influence results just to suit our particular agenda or interests. An investigator who knows what you are given, drug or placebo, but owns lots of stock in the company, or is hoping for special favors from the pharmaceutical company sponsor, for instance, is likely to perceive events in a light favorable to the outcome of the study.

Now, most studies are not double-blind, placebo-controlled studies. These are notoriously difficult studies to engineer; raise lots of ethical questions (can you not treat a person with an aggressive cancer, for instance, and administer a placebo?); often require substantial numbers of participants (thousands), many of whom may insist on payment for devoting their time, bodies, and perhaps even encountering some risk; and are tremendously expensive, costing many tens of millions of dollars.

For this reason, many other study designs are often followed. They are cheaper, quicker, may not even require the active knowledge or participation of the group being studied. That’s not to say that the participants are being tricked. It may simply be something like trying to determine if there are more heart attacks in people who live in cities compared to rural areas by comparing death rates from heart attack from public records and population demographic data. Or, a nutritional study could be performed by asking people how many eggs they eat each week and then contacting them every month for 5 years to see if they’ve had a heart attack or other heart event. No treatment is introduced, no danger is added to a person’s established habits. Many epidemiologic studies are performed this way.

The problem is that these other sorts of study designs, because they generate less confident results, are not generally regarded as proof of anything. They can only suggest the possibility of an association, an hypothesis. For real proof to occur, a double-blind, placebo-controlled may need to follow. Alternatively, if an association suggested by a study of lesser design might, by reasons of a very powerful effect, be sufficient. But this is rare. Thalidomide and catastrophic birth defects are an example of an association between a drug and fetal limb malformation that was so clear-cut that no further investigation was required to establish a causative association. Of course, no one in their right mind would even suggest a blinded study.

Where am I going with this tedious rambling? Lately, the media has been making a big to-do about several studies, none of which are double-blind, placebo-controlled, but were cross-sectional sorts of observations, the sorts of studies which can only suggest an effect. This happened with Dr. Steve Nissen’s study of Avandia (rosiglitazone) for pre-diabetes and risk for heart attack and the recent study suggesting that cancer incidence is increased when LDL cholesterol is low. Both were observations that suggested such associations.

Now, those of you following the Heart Scan Blog or the www.cureality.com website know that we do not defend drug companies nor their drugs. In fact, we’ve openly and repeatedly criticized the drug industry for many of its practices. Drugs are, in my opinion, miserably overused and abused.

But, as always, I am in the pursuit of truth. Neither of these studies, in my view, justified the sort of media attention they received. They are hypothesis-generating efforts—that’s it. You might argue that the questions raised are so crucial that any incremental risk of a drug is simply not worth it.

Despite the over-reaction to these studies, good will come of the fuss. I do believe that heightened scrutiny of the drug industry will result. Many people will seek to avoid prescription drugs and opt for healthy changes in lifestyle, thus reducing exposure to costs and side-effects.

But beware of the media, acting as our Chicken Little, reporting on studies that prove nothing but only raise questions.

200 point drop in heart scan score

11. August 2007 William Davis (0)

Some of the math-savvy will have noticed that we often report drops in CT heart scan scores on a percentage basis. Unfortunately, it this were a competition (which, of course, it is not), this would be unfair.

A score of 50, for instance, that drops "only" 25 points would represent a 50% drop in score.

But someone with a score of 1050 who drops his or her score the same quantity, or 25, will have dropped their score less than 5%.

In other words, the magnitude of your starting score determines how large a percentage drop you achieve, even when the absolute, or real, quantity of plaque reversal is the same as someone who begins with a lower score.

I qualify this discussion in this vein because of Grady's story. Grady, a soon-to-retire attorney, started with a heart scan score of 1151. On the Track Your Plaque program, he saw his score drop nearly 200 points--200 points!

But, if we gauged Grady's success just on a percentage basis, he dropped his score only a measly 17% or so. (Imagine the headlines if this program were sponsored by a drug manufacturer. The Track Your Plaque program proudly has nothing to do with the drug industry.)

Of course, the Track Your Plaque program is not a competition. It is an effort to help everyone possible, the more the better. Even if Grady failed to set a new Track Your Plaque record gauged on a percentage basis, he will have achieved an extraordinary advantage in health: the virtual elimination of the dangers of heart disease.

With this drop in score, Grady's risk for heart attack plummets from a spine-chilling 25% per year to nearly zero. (I know of NO other program that can claim such a track record.)

Grady's full story will be reported in the August, 2007 Track Your Plaque newsletter.

How tough is the Track Your Plaque 60-60-60 target?

9. August 2007 William Davis (3)

One of the basic requirements that stack the odds in your favor of stopping or dropping your CT heart scan score is to achieve basic lipid targets of 60-60-60.

In other words, we generally see best results when LDL is reduced to 60 mg/dl, HDL raised to 60 mg/dl, triglycerides reduced to 60 mg/dl. Now, these are not absolute requirements. Someone can have a spectacular drop in heart scan score even with an HDL of 56, LDL of 71. But the "Rule of 60" provides a useful target that is easy to remember, packs real power, and is clearly beyond that achieved with conventional approaches.

People often ask, "Just how tough is it to get to these targets?"

It's really not that tough. Interestingly, whenever I tell my cardiologist or primary care colleagues that I advocate these 60-60-60 targets, they declare that it's tough, perhaps impossible, except for the most highly motivated.

I agree that it requires motivation. A cigarette-smoking, TV-addicted, 70-lb overweight, chip- and pretzel-eating couch potato is not going to achieve them.

On the other hand, you don't have to be a marathon running vegetarian to do it, either.

Most people, in fact, engaged in the Track Your Plaque program achieve the 60-60-60 targets---or exceed them. It's not uncommon, for instance, for HDL to skyrocket to 80 or 90 mg/dl with many of our strategies. (Of course, if your starting HDL is 20 or 25 mg/dl, 80 or 90 is not possible with current technology.)

But it certainly does require more than the "Take Lipitor and stick to your low-fat diet" approach that is the mantra repeated in the vast majority of medical offices across the U.S. For instance, reducing LDL to 60 mg/dl when starting at 170 mg/dl will require addition of oat bran and other soluble or viscous fibers; raw almonds and walnuts; perhaps the use of Benecol butter substitute; reduction or elimination of wheat products if small LDL comprises a substantial proportion of LDL particles. Reducing triglycerides requires the generous use of omega-3 fatty acids from fish oil. Attention to vitamin D must be a part of the effort.

So, yes, it is not as simple as the conventional approach. But the results are far superior in reducing or eliminating heart attack and in dropping your heart scan score.

But it can be done. We do it every day.

Vitamin D2 belongs in the garbage

8. August 2007 William Davis (15)

It happened yet again.

Mel came to the office. CT heart scan score: 799--quite high, enough to pose a real threat very soon. Thus, no time to lose in instituting an effective prevention program.

We do the usual--identify the six causes of coronary plaque; begin fish oil, show him how to correct his plaque causes. You've heard it before.

Vitamin D blood level in March: 17 ng/ml--severe deficiency.

Vitamin D replacement needs to be a part of his coronary plaque control program. So I suggested 6000 units per day of an oil-based preparation of vitamin D3 (cholecalciferol). Conveniently, there is a Vitamin Shoppe outlet across the street from my office. I just point and tell people to go across the street.

Mel did just that. However, he also informed his primary care physician about his vitamin D deficiency. His primary physician promptly told him he needed to take a prescription form of vitamin D and not to bother with just a supplement.

So Mel stopped his vitamin D capsules and started taking vitamin D prescription "medication." Mel figured, naturally, that if it requires a prescription, it must be better. Unfortunately, Mel and his doctor failed to pass the change in strategy onto us.

So, four months later, Mel got repeat vitamin D blood level: 19 ng/ml.

I've seen this too many times. The prescription form of vitamin D is nonsense. There's hardly any effect on blood levels of vitamin D3 at all. The body's conversion of this non-human form of D is extremely inefficient and therefore virtually useless. While it raises the blood level of vitamin D2 (ergocalciferol) and thereby total D (D3 + D2), there is negligible effect on the real human and active form, D3.

How and why this preparation got through the FDA process to obtain approval as a drug is beyond me, though I am not a defender of FDA practices and politics.

This notion that "if it's a prescription, it must be better" is a fiction perpetuated by the drug industry. The same principle gets tossed around with fish oil, hormones like estrogens and testosterone, and others. Often, the principal difference between prescription and non-prescription is patent protection. Patent protection provides profit protection. Selling a product without patent protection can be risky business. It's certainly less profitable.

As always, getting at the truth is sometimes the most difficult job of all. Prescription vitamin D belongs in the garbage. Vitamin D capsules (gelcaps) do the job and do it well, over and over, with reliable, consistent and substantial rises in blood levels of 25-OH-vitamin D3. I take 6000 units per day (3 2000 unit capsules) that cost me $5.99 for a bottle of 120 capsules, or about $4.50 a month.

And nobody--nobody--pays me to say this. I say it because I believe it's true.

Angioplasty vs. Track Your Plaque

5. August 2007 William Davis (10)

What does angioplasty have over the Track Your Plaque program?

Well, first of all, the Track Your Plaque program has a lot to boast about. What other approach can claim to have reduced heart disease 30, 40, 51, and now 63%? That's as close to a cure that's ever--EVER--been achieved. Statin drug manufacturers can talk about an occasional 1, 2, or 5% reversal. We're talking 10 times more.

The Track Your Plaque program also uses as little prescription medication as necessary. Fish oil, vitamin D, coenzyme Q10, niacin--some of the frequent tools used for plaque reversal in our program. Yes, we do use prescription medications, but only when there is truly a benefit and nutritional strategies have failed to achieve the goals we're seeking. We do not endorse shotgun prescription approaches conceived of by some marketing department at a pharmaceutical company.

So what possible advantage can coronary angioplasty have? Why don't more people embrace a program like Track Your Plaque that has already proven itself enormously effective?

Because angioplasty is easy. There's little worrying ahead of time. Just wait for the symptoms or other problem to appear, go to the hospital and get your procedure. You can live the free and easy life beforehand--no exercise, no diet efforts, no nutritional supplements. Just be sure to go to the hospital when suspicious symptoms strike. (Of course, you gamble that you survive the appearance of symptoms, a process 30-50% of people fail to survive.)

That means you can eat all you want, drink all you want, save the money you otherwise might have thrown away on supplements, pocket the monthly costs of an exercise club membership, etc. Go to the hospital when you experience the sensation of an anvil on your chest or of suffocation, let the emergency room do their thing, meet your cardiologist, go to the catheterization laboratory, get two or three stents, go home the next day!

Why bother with a prevention program, especially one that requires involvement, learning, and effort like Track Your Plaque?

Because it's your way to stack the odds enormously in your favor of 1) surviving the appearance of symptoms, 2) avoiding the prospect of heart procedures, which are not as clean and easy as they often seem, 3) have a longer lasting durability than a stent which could buy you a couple of years before your next procedure or heart catastrophe, and 4) it's the right thing to do for the sake of the huge societal cost of heart disease.

Many of you have the equivalent of a cure for heart disease at your fingertips. Unless you have a soft spot in your heart for hospitals, cardiologists, or the pharmaceutical or medical device industry, there isn't a choice.

Plaque is like money

3. August 2007 William Davis (0)

In case anyone missed this in the June, 2007 Track Your Plaque Newsletter, I'm again posting how we calculate the annual rate of score increase, should it occur.

For instance, say your score in January, 2005, is 100. In November, 2006, you undergo another scan and the score is 140. Obviously, your score has increased an undesirable 40%. But what is the annual rate of score increase, the amount of increase per year?

In this example, the annual rate of score increase is 19%--not anywhere near as bad as the 40% that can scare the heck out of you.

Obviously, the best rate of heart scan score increase is a negative number, i.e., a drop in score from, say 100, to 60. You might even eliminate the need for this calculation altogether if you drop your score.

Nonetheless, whenever there is a score increase over an uneven period of time, a fraction of year(s), this is the method we use to annualize the calculation. The equation we use is a modified form of the annual compound interest equation using continuous compounding, since that’s how coronary atherosclerotic plaque grows--just like money. The difference is, of course, is that while you might want more money, you certainly don't want more plaque.

You will need a calculator for this calculation, one with an exponential “y to the power x” function. For ease, calculate "1/t first, then use it as the “x” exponent on your y^x function and "(score 2 / score 1)" as the "y".

Annual rate of plaque growth (APG) = ( score 2 / score 1 ) ^1/t - 1

Multiply the result by 100 to yield a percent.

“Score 1” is your 1st heart scan score, “score 2” is your 2nd (or any subsequent heart scan score); “t” is the amount of time between the two scans expressed in years in decimal form. Time between scans should be expressed in years or fractions of years. To obtain the time interval in fractions of years, simply divide the number of months between scans by 12 (e.g., 18 months / 12 = 1.5 years ; 22 months / 12 = 1.83 years).

It’s not as tricky as it looks. For example, if your first heart scan score is 300 and your next scan 16 months later (or 16/12 = 1.33 years) is 372, then:

Annual rate of plaque growth (APG) = ( 372 / 300 ) ^1/1.33 - 1 = 0.175

Multiply 0.175 x 100 = 17.5% annual rate of plaque growth

Some scan centers will do the calculation for you as part of a repeat scan. However, the equation can be used if you're left on your own, or if you go to a different scan center. If this is too much effort, perhaps it's just another reason to add to the list of reasons to drop your heart scan score!

Triglycerides: What is normal?

1. August 2007 William Davis (2)

In The Track Your Plaque program, we advocate decreasing triglycerides to 60 mg/dl or less.

That's the level of triglycerides that minimize the presence of triglyceride-containing undesirable lipoproteins causing plaque, such as small LDL, VLDL, and the after-eating persistence of IDL (intermediate-density lipoprotein, a bad player). (The enzyme, cholesteryl-ester transfer protein, or CETP, is responsible for exchanging one triglyceride molecule for one cholesterol molecule between HDL and other lipoprotein particles. Thus, an excess of triglyceride availability permits CETP to operate unrestrained, creating more undesirable lipoproteins. This was the basis for Pfizer's now defunct CETP inhibitor, torcetrapib.)

Of course, this triglyceride target is far below that of the conventional guidelines. The Adult Treatment Panel-III of the National Cholesterol Education Panel suggests a triglyceride level of 150 mg/dl is okay.

In my view, a level of 150 mg/dl is highly abnormal, permitting the persistence of multiple lipoprotein particles and virtually guarantees plaque growth. In short, triglycerides of 150 are awful.

Curious thing: Successful participants in our program, i.e., people who achieve desirable weight, reduce processed carbohydrate junk foods and saturated fat sources, and aim for the 60-60-60 targets for conventional lipids, commonly end up with triglyceride levels of 25-50 mg/dl.

We have seen many people drop their heart scan scores just by achieving a triglyceride level of 60 mg/dl or less. So achieving a lower level below 60 is not necessarily a requirement for coronary plaque regression.

But it makes me wonder if a triglycere level of 30s or 40s is the level for perfect health. These are levels ordinarily regarded as impossibly low. When colleagues see the numbers we readily and routinely achieve, they declare that the numbers are spurious, temporary, or just flukes. "No way you can do that all the time!"

This level also seems to, in virtually all cases, eliminate the triglyceride-containing undesirable lipoproteins small LDL, IDL, etc., and allow full conversion of HDL into the healthy, large fraction.

Should we move the Track Your Plaque triglyceride target to below 45 mg/dl or even lower? I don't think so, but it makes me wonder.

Are happy people more likely to reduce heart scan scores?

18. December 2006 William Davis (0)

I was talking to Darryl, a patient today: 71 years old with a heart scan score of 378, as well as an enlarged aorta (4.5 cm).

We had identified numerous lipoprotein abnormalities 12 months ago and advised him on a program for correction. His patterns included small LDL, high triglycerides, sky-high IDL (VERY important when you have an enlarged aorta), and lipoprotein(a). Blood pressure was also high, another crucial fact to correct when the aorta is enlarged.

Anyway, Darryl corrected lipoproteins to perfection: basic lipids were substantially better than 60-60-60; lipoprotein(a) was reduced well into the desirable range; IDL was eliminated; blood pressure was 108/64. Repeat heart scan score: 354.

There's nothing spectacular about Darryl's story, except that, despite these issues, Darryl was a happy man. He smiled throughout our conversation. He has told me on several occasions how grateful he is for the life he has.

Darryl is not wealthy. He retired around 4 years ago and fills his day with helping his wife, walking outdoors, helping out at his church, and contributing to the care of his grandchildren. Through all this Darryl is incurably, unfailingly, and irrepressibly happy.

It made me think back through all the other people who've also had great succes in their Track Your Plaque program. It struck me that, for the most part, they too were a happy bunch: generally optimistic, happy, not overly stressed nor prone to extremely stressful responses to stressful situations. All seem to also be grateful for the good in their lives, though most had no more money than the average person and had their share of difficulties in life. In fact, I can only recall one person who reversed coronary plaque who was an angry, pessimistic personality. Just one.

Could it be that happy, optimistic people are more likely to reverse coronary plaque? It would, after all, be consistent with all the other observations that type A personalities have more heart attack, etc.

Anyway, this is just an informal observation but one that seems very consistent. Track your plaque--and be happy!

Don't overdo the vitamin D

17. December 2006 William Davis (1)

As time passes and I advise more and more people to supplement vitamin D, I gain increasing respect for this powerful "vitamin". I am convinced that vitamin D replacement is the reason for a recent surge in our success rates in dropping CT heart scan scores. I believe it is also explains the larger drops we've been witnessing lately--20-30%.

But vitamin D can be overdone, too. Too much of a good thing . . .

Despite being labeled a "vitamin", cholecalciferol is actually a hormone. Vitamins are obtained from food and you can thereby develop deficiencies because of poor intake. Deficiency of vitamin C, for instance, arises from a lack of vegetables and fruits.

Vitamin D, on the other hand, is nearly absent from food. The only naturally-occuring source is oily fish like salmon and sardines. Milk usually has a little (100 units per 8 oz) because milk producers have been required by law to put it there to reduce the incidence of childhood rickets.

A woman came to me with a heart scan score of nearly 3800, the highest score I've every seen in a woman. (Record for a male >8,000!) She was taking vitamin D by prescription from her family doctor but at a dose of 150,000 units per week, or approximately 21,000 units per day. This had gone on for about 3-4 years. This may explain her excessive coronary calcium score. Interestingly, she had virtually no lipoprotein abnormalities identified, which by itself is curious, since most people have some degree of abnormality like small LDL. Obviously, I asked her to stop the vitamin D.

Should you be afraid of vitamin D? Of course not. If your neighbor is an alcoholic and has advanced cirrhosis, does that mean you shouldn't have a glass or two of Merlot for health and enjoyment? It's a matter of quantity. Too little vitamin D and you encourage coronary plaque growth. Too much vitamin D and you trigger "pathologic calcification", or the deposition of calcium in inappropriate places and sometimes to extreme degrees, as in this unfortunate woman.

Ideally, you should have your doctor check your 25-OH-vitamin D3 blood levels twice a year in summar and in winter. We aim for a level of 50 ng/ml, the level at which the phenemena of deficiency dissipate.

"It must have been the statin"

13. December 2006 William Davis (0)

After four years of trying, Randy finally reduced her heart scan score. It not only dropped, it plummeted. After four previous scans that showed 25% or more increases, she'd finally dropped her score 23%. (I Blogged about Randy's case a few weeks ago.)

Randy also works for a cardiologist. When she told him that she had reversed her coronary plaque and reduced her heart scan score by 23%, he said, "It must have been the statin agent."

Randy was indeed on a statin drug at a low dose. But she also had taken great efforts in exercise, food choices, fish oil, and vitamin D. In fact, her score had progressed dramatically while she was taking the drug. Put simply, it was not the statin.

But that is the mindset of the conventionally thinking cardiologist. Stent, bypass, or statin drug--what else is there? Even with crystal clear evidence for coronary plaque regression, they refuse to acknowledge that tools that are not in their everyday consciousness could have achieved so spectacular a result.

Given a choice, 9 out of 10 cardiologists would rather put a stent in and walk away $2000 richer for an hour of work. Don't allow them to have this choice. Take control now.

Statin Drugs May Help the Healthy:
Cholesterol-Lowering Statin Drugs May Benefit People Without Heart Disease

That's the headline on WebMD, reporting the findings of a recent study published in the Archives of Internal Medicine. In reality, it wasn't really a study at all, but a re-analysis of previously published data, a so-called meta-analysis.

Nonetheless, the University of Toronto group re-analyzed the results of several studies, pooling data on 28,000 people, none of whom had known coronary disease. The results were similar to the results of the studies that were reported individually: a 29% reduction in heart attack and other "events" in people taking statin drugs.

What's surprising to me is this notion that statins, or any other treatment for that matter, prevent heart attack in people without heart disease. This is idiotic. Of course they had coronary heart disease. You can't have a heart attack in the absence of coronary disease. (There are very rare exceptions, like cocaine users, who experience coronary spasm from the drug).

What the study shows is that people with unrecognized heart disease experienced a reduction in heart attack. What it also means is that many, many people truly without heart disease were unnecessarily treated. As you'd predict, the drug manufacturers love this sort of broad, untargeted use of their drugs. It's an approach that brings in billions of dollars of revenues. The article on WebMD, in fact, was accompanied by three ads for various cholesterol drugs on this single page story.

What if only people with heart disease, as identified by CT heart scan scores, were treated? You would indeed witness an even larger reduction in heart attack risk, because the group receiving treatment both has the disease and is thereby at greater risk. Treatment should yield even greater risk reduction than treating broad groups who superficially appear to not have heart disease.

Ignore this nonsense about statin drugs reducing heart attack risk in people without heart disease. If you don't look for it, you won't know you have it. Once again, you can be lots smarter than the media. Get a heart scan and find out if your risk is worth reducing.

Heart attack guaranteed

10. December 2006 William Davis (0)

What if you knew for a fact that your risk for heart attack was 100% by, say, age 58? This is indeed true for many people, though at age 60, 65, 70--or 45.

In other words, unless something were done about the causes of heart disease, you would inevitably suffer a heart attack at 58.

What sort of action could you take at age 45?

Obviously, not smoking is an absolute requirement. Continue and you may as well start getting your affairs together.

How about exercising and eating a generally healthy diet? Will your risk be reduced to zero? No. It might be reduced 20-30%, depending on genetic factors.

How about a statin drug? Watch TV ads during Oprah, and you might think it's a cure. But in reality, while it is a financial bonanza for the drug manufacturers, it will reduce risk for heart attack by 30%.

(Note that risk reduction by following multiple strategies is not necessarily additive. In other words, if you have a healthy lifestyle and take a statin agent, is risk reduced 60% (30 + 30)? No, because the effects may overlap.)

So, eating healthy, exercising, and taking a statin drug might reduce risk 35-40%, maybe 50% in the best case scenario. Would you be satisfied? Most would not.

Add fish oil at a truly therapeutic dose. Risk reduction by itself: 28%.

Add niacin or other strategies for correction of your individual, specific causes of heart disease: Now we're up to 90% reduction.

Throw in a tracking process to prove whether or not atherosclerotic plaque has progressed or reversed. Now we're approaching 100% if plaque reverses. The only way I know how to track plaque is through CT heart scans. What other test is readily available to you with low radiation exposure, yet is relatively inexpensive and precise? It certainly is not stress testing, heart catheterization, CT angiograms, or other techniques. Cholesterol won't tell you. Besides CT heart scans, there's nothing else I know of.

Let's fact it: For many people, uncorrected risk for heart attack is truly 100% at some age. Take action while you can.

That, in a nutshell, is the Track Your Plaque program.

Heart scan curiosities 3

10. December 2006 William Davis (7)

This is a sample image from the heart scan of a 54-year old, 212 lb, 5 ft 2 inch woman. The heart is the whitish-gray in the center; lungs are the dark (air-filled) areas on either side of the heart. Note the massive amount of surrounding gray tissues that encircles the heart and lungs. This is fat. At this weight, the diameter of total fat exceeds the combined diameter of the heart and lungs. If we were to show the abdomen, there would be even more fat. (The image shows the body not well centered because the technologist centers the heart, since this is, after all, a heart scan.)

This is a 55-year old, 151 lb, 5 ft 4 inch woman. Note the contrast in the quantity of fat tissue surrounding the chest, a much more normal appearance. Note that this woman is still around 25 lb over ideal weight, but not to the extreme degree of the woman above.

Another curious observation: Note the more whitish streaking in the heavier woman's lungs. Heart scans are performed while holding a deep inspiration (a deep breath inwards), mostly to eliminate lung respiratory motion during image acquisition. Nonetheless, the heavier woman's lungs are not as fully expanded as the more slender woman. In other words, the heavier woman cannot inflate her lungs as effectively as the thinner woman. Ever notice how breathless heavy people are? Some of this effect is just being out of shape. But there's also the added effect of the abdominal fat exerting upwards compression on the lung tissues, and the constrictive effect of the encircling fat mass. At the beginning of inspiration, the chest fat exerts the resistance of inertia to inspiration that is absent, or less, in a slender person. With each breath, the heavy woman must move 50 lbs or so of surrounding fat mass just to inhale.

The heavier woman is, in effect, suffocating herself in fat.

The distortions to the human body incurred by extreme weight gain are both fascinating and shocking. I hope you're breathing easily.

The shameful "standard of care"

10. December 2006 William Davis (1)

John's initial heart scan four years ago showed a score of 329. His physician prescribed Zocor for a somewhat high LDL cholesterol.

One year later, John asked for another scan. His score: 385, a 17% increase. John exercised harder and cut his fat intake.

This past fall--3 years after his last scan--John had yet another heart scan. Score: 641, a 66% increase over the last scan, all the while on Zocor.

John sought an opinion from a reputable cardiologist. He concurred with the prescription of Zocor and advised annual stress tests. That's it.

Followers of the Track Your Plaque approach know that the expected uncorrected rate of increase in heart scan score is 30% per year. On Zocor or other cholesterol reducing statin agent, a common rate of growth is between 18-24% per year--better but not great. Plaque growth is certainly not stopped.

But that is the full extent of interest and responsibility of your cardiologist. Prescribe a statin drug, perform a stress test, and the full extent of his obligation has been fulfilled. In legal terms, your physician has met the prevailing
"standard of care". No more, no less.

In other words, the prevailing standard of care falls shamefully short of what is truly possible. For the majority of the motivated and interested, coronary plaque reversal--reduction of your heart scan score--should be the standard aimed for. It's not always achievable, but it is so vastly superior to the prescribe statin, wait for heart attack approach endorsed by most cardiologists.

Heart scan curiosities 2

9. December 2006 William Davis (2)

This is an example of a so-called "hiatal hernia", meaning the stomach has migrated through the diaphragmatic hiatus into the chest--the stomach is literally in the chest. This example is an unusually large one. Hiatal hernias can cause chest pain, indigestion, and a variety of other gastrointestinal complaints. Heart scans are reasonably useful to screen for this disorder, though very small ones could escape detection by this method.

Sometimes, you can actually hear the gurgling of stomach contents (the common "growling" stomach) by listening to the chest. Large ones like this actually crowd your heart (the gray structure above the circled hernia), irritating it and even causing abnormal rhythm disorders. The dense dark material within the hernia represents lunch.

I would not advocate CT heart scans as a principal method to make a diagnosis, but sometimes it just pops up during a heart scan and we pass it on to the person scanned.

Vitamin D: New Miracle Drug

6. December 2006 William Davis (0)

At the meetings of the American Society of Bone and Mineral Research, Dr. Bruce Troen of the University of Miami detailed his views on the extraordinary benefits of vitamin D replacement. He also talked about the enormous problem of unrecognized vitamin deficiency.

“There’s a huge epidemic of hypovitaminosis D, and the real key here is not just that it’ll benefit you from a bone and neuromuscular standpoint, but if you correct hypovitaminosis D and the corresponding secondary hyperparathyroidism, then you’re going to decrease prostate cancer, colon cancer—actually “up to 17 different cancers, breast cancer included.”

Unfortunately, Dr. Troen did not talk much about the heart benefits of vitamin D, likely since the data is scant, nearly non-existent. However, if the Track Your Plaque experience means anything, I predict that vitamin D replacement will become among the most powerful tools you can use to gain control over coronary plaque.

Read the text of a report from the Internal Medicine World Report to read more of Dr. Troen's comments.

Heart disease "reversal" by stress test

5. December 2006 William Davis (3)

Here's an interesting example of a 71-year old man who achieved "reversal" of an abnormality by a nuclear stress test.

This man underwent bypass surgery around 10 years ago, two stents three years ago. A nuclear stress test in April, 2005 showed an area of poor blood flow in the front of the heart. On the images, normal blood flow is shown by the yellow/orange areas. poor or absent blood flow is shown by the blue/purple areas within the white outline.

Now, I can tell you that this man is no paragon of health. He's only accepted limited changes in his otherwise conventional program--in other words, someone who I'd be shocked achieved true reversal of his heart disease. (I didn't have him undergo any CT heart scans because of the difficulties in scoring someone who has undergone bypass surgery and stents, and because of limited motivation. True plaque reversal is for the motivated.)This patient did, however, accept adding fish oil and niacin to his program.

Nonetheless, stress testing can be helpful as a "safety check". Here's the follow-up stress test:

You'll notice that the blue/purple areas of poor blood flow have just about disappeared. This occurred without procedures.

Does this represent "reversal"? No, it does not. It does represent reversal of this phenomenon of poor flow. It does not represent reversal of the plaque lining the artery wall. That's because improvement of flow, as in this man, can be achieved with relatively easy efforts, e.g., improvement in diet, statin drugs, blood pressure control, etc. True reversal or reduction of coronary plaque, however, is tougher.

If blood flow is improved, who cares whether plaque shrinks? Does it still matter? It does. That's because the "event" that gets us in trouble is not progressive reduction in blood flow, but "rupture" of a plaque. A reduction in plaque--genuine reversal--is what slashes risk of plaque rupture.
