Fatal underdose

27. April 2008 William Davis (8)
Since vitamin D has been the topic of a fair amount of media coverage, I've received many questions about this fascinating "nutrient." A day doesn't go by without several nurses, friends, even fellow physicians stopping me to ask about vitamin D.

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

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

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

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

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

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



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

Members of Track Your Plaque: Watch for the 30-some page booklet, The Track Your Plaque Complete Handbook on Vitamin D and Heart Health, which will be released in the next day or two.

Is direct-to-consumer drug marketing a failure?

23. April 2008 William Davis (4)
According to the poll just completed by 80 participants on The Heart Scan Blog, 50% of respondents said they were less likely to take a drug after viewing an advertisement for it. A whopping 3 (4%) said that they would be more likely to take the drug after viewing an advertisement.

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

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

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

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

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

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

Cheerios and heart health

22. April 2008 William Davis (11)


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

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

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

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

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


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

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

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

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

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

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

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

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

The IF Life: Intermittent fasting

21. April 2008 William Davis (4)
There's a wonderful blog called The IF Life: Intermittent Fasting and Instant Freedom. It is written by personal trainer (and apparently former corporate bigshot), Mike O'Donnell.

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






Intermitent Fasting 101: How to Start, Part I

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

What is IF?

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


How do I begin to IF?

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

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

Daily Fasting (15-19 hours):

The Advantages are:

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


The Disadvantages are:

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


The advantages are:

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


Disadvantages:

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


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

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

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


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

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

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

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

Warfarin is scary stuff

19. April 2008 William Davis (16)
Gilbert is a 58-year old high school science teacher.

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

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

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

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

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

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

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

I fear that the culprit might be warfarin.

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

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

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

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

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

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

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

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

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

Lipoprotein(a) Research Foundation

16. April 2008 William Davis (18)
There is no longer any doubt that lipoprotein(a) is a major causal factor in heart disease:

Peltier M et al.Elevated serum lipoprotein(a) level is an independent marker of severity of thoracic aortic atherosclerosis.

Willeit J et al. Lipoprotein(a) and asymptomatic carotid artery disease. Evidence of a prominent role in the evolution of advanced carotid plaques: the Bruneck Study.




From just about any direction, Lp(a) has been conclusively associated with atherosclerotic disease. We have more than enough data proving association.

But there are two areas of desperate need:

1) Data on effective treatments.

2) Raising awareness of this widely unknown (among the public) and ignored (among health professionals) genetic condition.

Treatment remains a real struggle. In a recent detailed Track Your Plaque Special Report, Unique Treatment Strategies for Lipoprotein(a) Reduction, we summarized the treatment approaches that have some power to reduce Lp(a) and/or its potential for causing heart disease. But, even armed with an appreciation for the world's scientific literature on this genetic condition, full control remains difficult for many people.

Track Your Plaque's HeartHawk has Lp(a) and he has struggled with this pattern for the last several years. He details some of his thoughts in a recent blog post.

More research and clinical studies are required and we need it soon if we hope to gain better control over this genetic pattern that affects up to 20% of people with coronary or vascular disease. Much of the needed research is sophisticated, background work similar to that being done by Dr. Santico Marcovina at University of Washington, Dr. Angelo Scanu at the University of Chicago, and Dr. Sally McCormick in New Zealand.

However, much of the needed research also consists of brief clinical experiences that detail whether or not there is an effect of various potential agents. Larger experiences, for instance, with potential treatment agents such as various phospholipid fractions, acetylcysteine, antibiotic regimens, some hormonal treatments, etc. could be performed quickly and simply. These studies would not require the $20 or $30 million typically spent by a drug company for a study, nor the several hundred million dollars to gain FDA approval of a new agent. They would simply be examinations of existing agents. These studies still cost money, require expertise, staff, and equipment. But the cost is a tiny fraction of the drug industry's investment in research. But it also means that investment return is nil from a drug manufacturer's perspective. Yet there are literally dozens, perhaps hundreds, of agents that hold some promise but have not been thoroughly studied.

For instance, if a specific modification of the phosphatidylcholine molecule were to generate a substantial Lp(a) reducing effect, Merck, Pfizer, and AstraZeneca would yawn--it is non-patent protectable, cannot be protected from competitors through the costly FDA approval process, and therefore is simply not worth their investment--regardless of whether it works or not.

(This is yet another example of how the drug industry, as well as hospitals and many health professionals, have lost sight of their real mission: to alleviate disease, not to profit from sickness.)

HeartHawk and I have discussed on a number of occasions whether a Lipoprotein(a) Research Foundation should be formed, an organization that seeks to fund the smaller research efforts that may accelerate productive research in Lp(a) and perhaps yield useful strategies faster than hoping for somebody to simply stumble on a treatment, or wait for the drug industry to create a unique, patentable entity that returns billions.

I'd like to propose that our Track Your Plaque program begin to fund such an effort. But a lot more help will be needed, particularly to generate the money to fund genuine, high-quality research from high-quality researchers.

If any readers of the Heart Scan Blog have any thoughts or insights into this process of creating a foundation, we'd appreciate your input.

More on ASTEROID

16. April 2008 William Davis (3)
Since we are on the topic of the ASTEROID trial and rosuvastatin, I'd make one more point before I start to sound like I'm plugging this drug (which I definitely am not).

In an informative Roundtable Discussion (open to subscribers to the American Journal of Cardiology; sorry) amongst Dr. Steve Nissen, principal investigator behind ASTEROID; and Drs. Vincent Friedewald, Christie Ballantyne, P. Shah, and William Roberts, Dr. Nissen made some interesting comments:


Dr. Shah: In ASTEROID, was the magnitude of atheroma volume change seen across different levels of LDL-C and HDL-C?

Dr. Nissen: No. There was no plaque regression seen in the 17 persons with LDL-Cs >/= 100 mg/dl, and there was little change in persons with LDL-Cs of 70 to 100 mg/dl. Only in persons with LDLs less than or equal to 70 mg/dl was there significant regression. The study was not powered to look for an HDL-C(which increased by 14.7%)-raising effect.



Interesting. In other words, ASTEROID, in a fairly internally consistent way, suggests that the lower the LDL is reduced, the more likely plaque regression is obtained. This is consistent with the Track Your Plaque experience, in which we've advocated reducing (calculated) LDL cholesterol to 60 mg/dl for the past several years.

Unfortunately, the message that the ASTEROID Trial sponsors, AstraZeneca, as well as the roundtable discussion panel (later in the discussion) try to make is that there is something magical about Crestor, that it yields benefits superior to other statin agents or other means of reducing LDL.

I disagree with this message. In the Track Your Plaque experience, we do aim for a similar LDL target. But we also employ a number of other strategies. We have also succeeded in regressing plaque without use of any statin drugs (though, admittedly, many people do require statin drugs to obtain LDLs in this range). We also witness magnitudes of reversal that often far exceed that seen in ASTEROID.

The Rountable Discussion is unfortunately tainted, as is the ASTEROID Trial itself, with deep drug industry financial involvement of the Roundtable participants. In fact, the discussion begins with a listing of the financial disclosures of the participants, a listing that occupies a full column of a two-column page. The potential biases of the participants doesn't necessarily invalidate the arguments, but to me suggests that participants are more likely to argue in favor of the sponsor's drug, or that participants were chosen because of these biases.

Why bother to even mention the ASTEROID Trial in a venue (the Heart Scan Blog, that is) that purports to seek unvarnished, unbiased truth in coronary plaque reversal? Because useful information can sometimes be found in unlikely places. Just like the four-year old child who blurts out an unexpected pearl of wisdom, so it can happen with the gobbledy-gook that emerges from the drug industry.

Every once in a while, they are worth paying attention to.

LDL cholesterol, statins, and plaque regression

13. April 2008 William Davis (12)
The ASTEROID Trial reported in 2006 examined the effects of LDL cholesterol reduction using the statin drug, rosuvastatin (Crestor), with coronary atherosclerosis quantified and tracked with intracoronary ultrasound. The Track Your Plaque report, New study confirms: LDL of 60 mg reverses plaque, on the ASTEROID Trial provides commentary on the results.


Though I remain skeptical that a statin-only treatment strategy can reverse coronary plaque in the majority of people, I do believe that the AstraZeneca-sponsored ASTEROID Trial does add to the wisdom on heart disease management. More importantly, it has served to raise awareness among both the public and my physician colleagues that atherosclerosis is indeed a potentially reversible condition.


Specifically, the ASTEROID results confirm that, either directly or indirectly, LDL cholesterol reduction achieved with statin agents does correspond to increasing degrees of plaque reversal. The mean (calculated) LDL cholesterol achieved in ASTEROID was 60 mg/dl, the same as the Track Your Plaque suggested LDL target.

Though the ASTEROID Trial is not news, I stumbled on a chart posted on the ASTEROID Trial website that clearly highlights how a number of other studies beyond ASTEROID have fallen into this pattern:





The graph reveals a linear relationship: The greater the reduction in LDL cholesterol with statin drugs, the greater the plaque regression ("change in percent atheroma volume"). (Several other studies not included in the graph also cluster into the same linear relationship.)

I am no supporter of drug companies, nor a defender of their policies and practices. But I do believe that their data can serve to teach us a few lessons. For instance, here is an (cherry-picked, to be sure) example of intracoronary ultrasound cross-sectional images before and after two years of rosuvastatin, 40 mg daily:





The color-coded/outlined atherosclerotic coronary plaque is shown shrinking, while the "lumen," or the path for blood to flow, enlarges. The reduction in coronary plaque is irrefutable. (The small circle within the lumen with the white halo surrounding it is the ultrasound catheter.)

If you and I were to choose a single treatment approach to coronary disease reversal, then 40 mg of rosuvastatin is probably at the top of the list. However, in the Track Your Plaque program, we do not advocate a single treatment strategy. While the Crestor-only approach is relatively straightforward--one pill a day--few people, in my experience, can tolerate this dose for any length of time. Patients invariably have to stop the drug or reduce the dose severely due to muscle aches when I've had patients try it. Contrary to the ASTEROID results, in my experience the majority of people, perhaps all, eventually give up with this improbable "one-size-fits-all" scheme.

The Track Your Plaque approach, while more complicated and involves several nutritional supplements and strategies, in my view addresses more causes of coronary plaque, is better tolerated, and provides health benefits outside of just LDL cholesterol reduction. It also minimizes or eliminates the need for prescription medication.

When is a calorie not a calorie?

10. April 2008 William Davis (8)
One ounce of raw almonds (about 23 nuts) contains:


6 grams protein

14 grams fat

6 grams carbohydrate

3.5 grams fiber

For a total of 163 calories per ounce.


(From the USDA Nutrient Database)


Calorie content of foods is determined by summing up the calories from each constituent: 1 gram of fat = 9 calories; 1 gram protein = 4 calories; 1 gram carbohydrate = 4 calories. Calorie content can also be directly measured using a device called a burn calorimeter, in which the amount of energy released from a specific food is measured by literally burning it and gauging precisely how much energy is released.


The problem with both of these methods is that it is assumed that all foods are digested with equal efficiency. That is, it assumes that a potato chip is as readily digested and absorbed as energy from table sugar, a pretzel, oatmeal, a piece of steak, or a handful of nuts. In real life, of course this is not true. Different foods are absorbed with varying efficiency.

For a long time I've suspected that some foods are very inefficiently absorbed. I've particularly suspected that raw nuts are relatively poorly absorbed and thus yield only a fraction of the calories ingested.

Among the studies recently reported at the Federation of the Association of Societies for Experimental Biology (FASEB) meetings I attended in San Diego this past week were several devoted to almonds.

One study, to my surprise, documented this phenomenon. In Manipulation of lipid bioaccessibility of almonds influences postprandial lipemia in healthy human subjects, it was determined that, of 100 calories ingested from the fat fraction of almonds, only about half was actually absorbed. The remaining half passed out in the stool. (They did this by collecting stool samples and comparing the fat composition after eating the different almonds prepartions. This is not discussed in the limited text of the abstract.) In addition, postprandial (after-eating) surges in triglycerides were much less with whole almonds compared to the oil separated from the nut (i.e., broken down into almond oil + defatted almond flour). The researchers attributed the difference to the inhibitory effects of the almond nut's "food matrix," or the structural properties of chewed foods.

Add to this the fact that, of 6 grams of carbohydrate per ounce of whole almonds, 3.5 grams are indigestible fibers. This means that 6 - 3.5 = 2.5 grams of digestible carbohydrates are present per ounce (assuming 100% release).

If we follow the reasoning that only about half the fat fraction of almonds are absorbed, and assume that the protein and carbohydrate (minus the indigestible fibers) are absorbed efficiently (100%), then we would re-calculate the calorie content of almonds to be 97 calories per ounce, or 40% less than calories calculated by composition or measured with a calorimeter.

If we were to assume that protein and carbohydrates were, like fats, inefficiently absorbed because of the effects of the food matrix, then one ounce of almonds yields 88 calories per ounce, or 46% less. This is, in fact, a likely scenario, since the food matrix is largely created by the cell wall and should impede digestive access to fat, protein, and carbohydrate equally.

My point? Almonds and other nuts at first appear to be calorically dense due to fat composition. However, this simplistic view of nuts is misleading because of the confounding effects of the food matrix. Stated differently: Whole foods yield less calories. And, judging by the postprandial triglyceride effects: Whole foods yield less undesirable effects, such as postprandial rises in triglycerides.

Some other observations with almonds included:

The effect of almonds on plasma lipids in persons with prediabetes This study confirmed the LDL-reducing and modest HDL-raising effects of almonds.

Almonds (Amygdalus communis L.) as a possible source of prebiotic functional food This curious observation suggests that almonds modify the bacterial flora of the intestinal tract in a positive way (like the cultures in yogurts).

Coenzyme Q10 and statin drugs

23. July 2006 William Davis (0)
Although drug manufacturers claim that muscle side effects from statin drugs occurs in only around 2% or people or less, my experience is very different.

I see muscle weakness and achiness develop in the majority of people taking Lipitor, Crestor, Zocor, Vytorin, etc. I'd estimate that nearly 90% of people get these feelings sooner or later.

Thankfully, the majority of the time these feelings are annoyances and do not lead to any impairment. Full-blown muscle destruction is truly rare--I've seen it once in over 10 years and thousands of patients.

The higher the dose of statin drug and the longer you take it, the more likely you're going to have muscle aches.

I experienced a strange phemomenon myself today. I worked outdoors for about 4 hours, pulling weeds, digging in the dirt, spreading topsoil. (I have an area of overgrowth in the front yard.) Admittedly, I worked pretty hard and it was a warm, humid day.

I was sore, as you'd expect at age 49. But, much more than that, I was exhausted--my muscles ached and I had barely enough strength to get up the stairs.

Hoping for some relief, I took an extra dose of coenzyme Q10. I usually take 50-100 mg per day. Today, when I felt this overwhelming muscle fatigue, I took an additional 200 mg. Within 10 minutes, I felt a surge of energy. It was, in fact, a perceptible, quite dramatic feeling.

I am thoroughly convinced, through my own experiences on Lipitor (I have a high LDL particle number despite a healthy lifestyle, among other abnormalities), and the experiences of many other people, that coenzyme Q10 can be an extremely useful tool to minimize the muscle aches and weakness of the statin drugs.

If you do indeed need to take one of these agents, coenzyme Q10 is worth knowing about. Supplementing coenzyme Q10 has, for me, been a real lifesaver. For many people, LDL reduction is a crucial part of their heart scan score control program. In my experience, many of them would not be able to take the drug without eozyme Q10.

Blast your LDL with oat bran and almonds

21. July 2006 William Davis (1)
Nearly all of us can use an extra boost in reducing LDL cholesterol. We have a large number of people, in fact, who have reduced LDL into the Track Your Plaque range of 60 mg/dl or less without the use of statin cholesterol-reducing drugs.




Oat bran is among my favorite ways to reduce LDL. Three tablespoons per day is a really effective method to drop your LDL around 20 points. There's twice the beta glucan (soluble, or "viscous", fiber)in oat bran, as compared to the more popular oatmeal. Add oat bran to anything you can think of: yogurt, cottage cheese, vegetarian chili, oatmeal, top desserts with it, etc. Some people struggle to find oat bran in the grocery store. Most health food stores that sell bulk products will have oat bran, usually less than a $1 per pound. Many grocery stores will also have an oat bran hot cereal along with the Cream of Wheat and oatmeal. That's okay, provided the only ingredient is oat bran--no added sugars, etc.





Another dynamite method to reduce LDL 10-20 points is adding raw almonds to your daily food choices. One or two handfuls per day works great. We find it at Sam's Club for around $12.99 for a 3 lb. bag. The plentiful fibers and monounsaturates in almonds keep you full and satisified, take the edge off your sweet tooth, and even blunt the blood sugar rise caused by other foods.

Both these foods are also great ways to combat the metabolic syndrome. Since both fiber-rich oat bran and almonds slow the release of sugars into the blood, blood insulin level is also reduced. This results in a happy cascade of less small LDL, increased HDL, and a reduction in inflammation.

All these wonderful effects contribute to inching you closer to success: dropping your heart scan score.

Pre-diabetes with normal blood sugar

20. July 2006 William Davis (0)
We pay special attention to pre-diabetes, in all its varied manifestations, in the Track Your Plaque program. This is because these factors are potent instigators of coronary plaque growth.

Early in the Track Your Plaque program we ignored these measures. After all, this is a program for heart disease risk reduction, not for mangement of diabetes. But we saw explosive rates of plaque growth when pre-diabetic factors were not controlled--even when cholesterol and related factors were under excellent control.

It became increasingly clear that factors associated with pre-diabetes needed to be managed, as well. This includes small LDL, increased blood sugar, high blood pressure, increased inflammation (as CRP).

Many people, however, have normal blood sugars (100 mg/dl or less) with a high blood insulin level (>10 microunits/ml). (This blood test is available in most laboratories.) This means that they have early resistance to insulin. The pancreas, the source of insulin, responds to the body's unresponsiveness to insulin by increasing insulin production.

Increased blood insulin with normal blood sugar will drive production of higher triglycerides, a drop in HDL, creation of small LDL, and inflammation--and coronary plaque growth, as evidenced by increasing CT heart scan score.

Blood insulin levels can be very effectively dropped by weight loss; exercise; reduction of processed carbohydrates like breads, pretzels, and breakfast cereals; and increased raw nuts and oat products; and vitamin D replacement to normal levels. Drug manufacturers are desperately trying to make this a mandate for drug treatment (Actos, Avandia), but are encountering resistance, since most people without overt diabetes don't want to take diabetic medication (rightly so!).

You and your doctor should consider insulin as a factor to track, especially if you have small LDL, low HSL, or high triglycerides, or any of the other manifestations listed above.

Sometimes small LDL is the only abnormality

19. July 2006 William Davis (0)
Janet is a 58-year old schoolteacher. At 5 ft 3 inches and 104 lbs, she had barely an ounce of fat on her size-2 body. For years, Janet's primary care physician complimented her on her cholesterol numbers: LDL cholesterol values ranging from 100 to 130 mg/dl; HDL cholesterol of 50-53 mg/dl.

Yet she had coronary disease. Her heart scan score: 195.

Lipoprotein analysis uncovered a single cause: small LDL. 95% of all of Janet's LDL particles were in the small category. What was surprising was that this pattern occurred despite her slender build. Weight is a powerful influence on the small LDL pattern and the majority of people with it are overweight to some degree. But not Janet.

How did she get small LDL if she was already at or below her ideal weight? Genetics. Among the genetic patterns that can account for this pattern is a defect of an enzyme called cholesteryl-ester transfer protein, or CETP. This is the exact step, by the way, that is blocked by torcetrapib, the new agent slated for release sometime in future (The manufacturer, Pfizer, is apparently going to sell this agent only packaged in the same tablet as Lipitor. This has triggered an enormous amount of criticism against the company and they are, as a result discussing marketing torcetrapib separately.)

Also note that Janet had a severe excess of small LDL despite an HDL in the "favorable" range. (See my earlier conversation on this issue, The Myth of Small LDL at http://drprevention.blogspot.com/2006/06/myth-of-small-ldl.html.)

With Janet, weight loss to reduce small LDL was not an option. So we advised her to take fish oil, 4000 mg per day; niacin, 1000 mg per day; vitamin D, 2000 units per day; use abundant oat bran and raw almonds, both of which suppress small LDL. This regimen has--surprisingly--only partially suppressed her small LDL pattern by a repeat lipoprotein analysis we just performed. We're hoping this may do it, i.e., stop progression or reduce her heart scan score.

The lesson: Small LDL is a very potent pattern that can be responsible for heart disease, even if it occurs in isolation. And, contrary to conventional thinking, small LDL can occur as an independent abnormality, even when HDL is at favorable levels.

Report from Washington II

16. July 2006 William Davis (0)
Today's discussions at the Society for Cardiovascular Computed Tomography (SCCT) focused on atherosclerotic "plaque characterization".

As CT scanners get better and better at imaging the various components of plaque, some fascinating issues emerge:

--CT heart scans provide insights into what exactly is contained in an individual's atherosclerotic plaque that are not often provided even during heart catheterization. In other words, CT heart scanning is, in many instances, superior to heart catheterization, since it provides images of the artery wall, not just the internal contents.

--Progression (i.e., increase) in heart scan score is a powerful predicter of heart attack risk. Dr. Matthew Budoff of UCLA argued persuasively that the annual rate of increase in score is probably the most accurate measure of risk available, superior to cholesterol and calculated measures like the Framingham risk score.

--Coronary calcium scoring remains the best method to gauge total plaque throughout the entire coronary tree. In a person free of symptoms, the risk of a cardiac "event" (heart attack, death, procedures) is low and additional imaging (like CT angiography) is generally unnecessary.


Dr. Budoff, among the true thought leaders in CT heart scanning, also recounted his perspective on the history of heart scans. He noted that the questions asked through the years have evolved:




1995-2000 Should we do coronary calcium scans?

2000-2002 Do high or low risk patients benefit from coronary calcium scoring?

2003-2004 What is the better scanner, EBT or MDCT?

2006 How often should we perform coronary calcium imaging?


I believe that Dr. Budoff summarizes wonderfully where the Track Your Plaque programs fits into the overall scheme of things: Serial (repeated)CT heart scans to gauge progression or reversal is the wave of the future. We shouldn't just be interested in identifying persons at risk for heart attack. We should also be interested in showing the person at risk exactly how to reduce or eliminate that risk.

Report from Washington

14. July 2006 William Davis (0)




I'm presently attending the Society for Cardiovascular Computed Tomography meetings in Washington, DC, along with 500 of my colleagues. It's exciting to see how interest in CT scanning for heart disease has balloonned in the past couple of years.

Several trends are noticeable today, based on the content and tone of the discussions:

--CT scanning of the heart, and imaging in general, is just getting started. In other words, the capabilities for CT scanners and other devices to detect heart disease (coronary and otherwise) are where the gasoline engine was in the 19th century. Scanning is getting faster, easier, safer, and more precise. Just as few people in 1905 could have predicted that automobiles would be computer-enhanced, high-speed, ubiquitous devices with several per household, the potential for CT imaging for heart disease is truly in its infancy.

--CT coronary angiography (so-called "64-slice CT scans") are not screening tests for hidden coronary disease in people without symptoms. I was grateful that this point has been made and reiterated by several speakers, as this is consistent with our views. Simple CT heart scans for coronary calcium scoring, in contrast, are screening tests. When the radiation exposure of CT angiograms are reduced to tolerable levels, then they may be used as screening tests. We are probably 3-4 years away from this point.

--Both stress testing and heart catheterizations will be partially replaced by CT scanning. In particular, over the next decade, you will see a dramatic drop in unnecessary catheterizations, i.e,, far less people saying "I had a heart cath but they told me that it was normal."


There has been heavy focus on applications of CT scanning for acute settings, particularly the emergency room and hospitals.

What has surprised me is that there is virtually no conversation whatsoever about the preventive uses of CT heart scanning. So far, only Dr. Daniel Berman of UCLA has shown that he has "seen the light": CT scans are a crucial tool for identification of early coronary plaque, and this tells us whether prevention is necessary and with what intensity.

There has been, however, no discussion at all about quantification of plaque in a program of reversal. Perhaps that should come as no surprise, given the imaging-technology focus of this convention. For most of my colleagues, prevention is also not terribly interesting. Identification and treatment of acute disease like impending heart attack is.

Of course, applying the information from your CT heart scan to empower you in a program and reversal is what the Track Your Plaque program is all about. I hope you see the light. I admit that it's not always easy to follow what we are advocating here. Perhaps not too different than telling someone in his horse-drawn buggy that one day he'll be driving a sleek car with onboard computerized mapping, air-conditioning, and micro-chips to modulate engine performance. He's probably tell us we're nuts.

I'll continue to update if any news relevant to our interests crops up in these meetings.

What about the Track Your Plaque failures?

14. July 2006 William Davis (0)
I’d love to tell you that the Track Your Plaque program track record is of 100% success. It’s not.

It is very successful. But we’ve had some people who have failed and failed BIG. These are the people who've undergone bypass surgery, received one or more stents, or had heart attacks. Lesser failures are the people who’ve had large, undesirable increases in heart scan scores of >30% in one year. (The expected rate of increase in your heart scan score without preventive efforts is 30% per year, on average.)

What can we learn from those failures? There were several characteristics that stand out among this small group:

· Non-compliance--meaning they just didn’t stick with it. They started out right but then rapidly lost interest in maintaining all the pieces of the program and neglected their fish oil, niacin, gain weight, etc. Matthew did this and ended up with three stents to his left anterior descending. His slow start was due to skepticism that the program worked and just plain forgetfulness.

· Extreme stress--One of our earliest failures was a 38-year old man whose heart scan score doubled in one year, despite doing everything right. But three family members, all close to him, died within the space of six months, including his mother and a brother. I regard this as one of those instances in which we were powerless, unfortunately, though it is a graphic example of the power of unresolved stress and grief.

· Having a “better way”--These are the couple of people who were convinced that they had a better way to control their heart scan score. David firmly believed that his two dozen supplements and exercise program would drop his score. Instead, they permitted a 42% increase. Lee relied exclusively on chelation, along with several supplements of his own design. Lee had three-vessel bypass surgery.

· Starting too late--Gerome started with a score of 1179, but also was having chest pressure with emotional stress. His stress test was abnormal, with the entire upper half of his heart not receiving blood with exercise on a stress nuclear study (“anterior ischemia”). Gerome received four bypass grafts. Unfortunately, Gerome never really had a chance to engage in the Track Your Plaque program, since his health and safety were in jeopardy as soon as he started.

Have we had any big failures of people who did everything right, were compliant, were not subject to extreme stress (more than just job stress, or financial worries), didn’t neglect the basic requirements of the Track Your Plaque program, and had sufficient time (at least 6 months to 1 year)? No, thankfully, we have not.

No one who has stuck to the program has had a big failure.

Be smarter than your cardiologist

12. July 2006 William Davis (0)
“Do you need a stent?”

Sad to say, but that sentence condenses the wisdom of over 90% of practicing cardiologists.

Prevention of heart disease means take Lipitor or some other statin and cutting the saturated fat in your diet. That’s it. Maybe throw in exercise.

Regression of coronary plaque? That phrase has only entered the conversation since the AstraZeneca-supported trial of Crestor succeeded in achieving 8% regression of plaque (Track Your Plaque Members: See News) as demonstrated by intracoronary ultrasound.



In other words, in the minds of my colleagues, it can’t be true until a drug company tells them it’s true. It’s beyond me why this brainwashing of otherwise intelligent people has occurred, but it is blatantly evident in practice.

Fish oil is another example. The spectacular benefits of fish oil have been known for 20 years. But only recently has it become a “mainstream” practice to recommend fish oil, largely because a drug manufacturer has put a preparation through the rigors of FDA approval (Omacor) and is now marketing directly to physicians. All of a sudden, fish oil is a good thing? No, it’s just achieved legitimacy in the eyes of practitioners because it graces marketing literature.

If you’re reading this, you’re likely interested in coronary plaque regression using the only tool available for you to measure, track, and regress coronary plaque: CT heart scans. Intracoronary ultrasound will achieve the same goal, but it is an invasive procedure performed at heart catheterization, involves threading a wire and imaging probe all the way down the artery, involves real risk of tearing the inner lining of the artery, and is costly (around $14,000-$20,000 for the entire package). Do it every year? That’d be nuts.

If you’re thinking about coronary plaque regression, using fish oil, concerned about patterns like low HDL and small LDL, aware of the vitamin D deficiency issue as a coronary risk factor, etc., you are far more aware than the vast majority of practicing cardiologists. They are interested in what new brand of anti-coagulant to use during their heart catheterization (because the product representative gushes about the new agent—only $1200 a dose!). Or, they are interested in gaining the procedural skills to put in a new device like a biventricular pacemaker. Regress/reverse coronary plaque? What for?

You already know that a conversation about coronary plaque reversal will not be obtained in your cardiologist’s office. Your family practice doctor or internist? Fat chance! Knee arthritis, pap smears, pneumovax inoculations, sore throats, gout, back pain—they’re spread far too thin to know anything more than the most superficial amount about coronary plaque control. Most know nothing.

That’s where we come in. That’s our mission: Educate people about the extraordinary tools that you have available to you, all in the cause of control or reversal of coronary plaque.

Why am I here?

11. July 2006 William Davis (0)
Frank came to the office for an opinion, sent by his (proactive) family physician.

"I really don't know why I'm here, to be honest."

Two years earlier, Frank had a heart attack, survived and received two stents to his circumflex coronary artery. He now took Zocor and his LDL cholesterol was a reasonably favorable 89 mg, total cholesterol 183 mg.

"I walk with my wife every other day. I've been avoiding fish fries. You'll never see me eat fast food."

Frank was correct: If we were going to engage in the conventional approach to coronary disease, Frank was on the right track. We would have postponed his next heart attack or procedure by a couple of years. Stroke, aneurysm, and other atherosclerotic manifestations would be set back, likewise, a few years.

Would Frank have profound control over his disease? Absolutely not. In fact, his disease had probably advanced a huge amount just in the two years since his stents were placed and he was on his "prevention" program. Without his current effort, his coronary plaque would be expected to grow 30% per year. On Zocor and his modest lifestyle efforts, plaque growth was probably in the 14-28% per year range.

So I explained the unique Track Your Plaque approach to Frank. First, we start with a CT heart scan to establish where he was starting. Although he had two stents in his circumflex artery, we still had two other arteries (LAD, right coronary) to score and track.

We then attempt to identify all hidden causes of his heart disease and then correct them.

Of course, Frank had multiple hidden causes:

--HDL too low at 38 mg/dl
--Small LDL-severe, in fact, with 95% of all LDL particles in the small category
--Triglycerides too high
--Excesses of several triglyceride-containing particles (VLDL, IDL)
--Pre-diabetes--Frank had both a borderline high blood sugar and a high insulin level. This is a sure-fire stimulus to coronary plaque growth.
--A severe deficiency of vitamin D (<20 ng/ml)
--An excessivelyhigh blood pressure during exercise--With a blood pressure of 190/102 on the treadmill.

There were others(!), but that was the bulk of the causes behind Frank's coronary disease.

Once Frank recognized that there was indeed a huge panel of hidden causes for heart disease, not just too much fat in his diet and LDL cholesterol, he jumped into the program head first.

The message: The conventional approach is absurdly oversimplified, a certain path to failure for the majority of people. Even if you don't have known coronary disease like Frank, but just have a heart scan score >zero, the same principles apply to you.

Catheterization to “define coronary anatomy”

10. July 2006 William Davis (0)
Gary is an avid jogger. On an average day, he runs 5-6 miles at a good clip. On two occasions recently, however, Gary experienced an ache in his left shoulder at mile 4. It was a toothache-like feeling, but he kept on going without difficulty.

Gary also had a heart scan score of 370.

Upon hearing of Gary’s score and his shoulder sensation, the cardiologist who saw him advised a heart catheterization “to define coronary anatomy”. (This is a real incident.)


What exactly does that mean? Why would Gary’s cardiologist need to define it?

In my view, this is an absurd notion. No one needs to “define coronary anatomy”. This catch-all phrase is commonly used to justify heart procedures. I believe what the cardiologist is saying is that it’s the easiest (for the cardiologist) and perhaps most generously reimbursed method to determine whether Gary’s symptoms are warning of an impending heart attack or not.

The problem is that the question can also be answered quite well by doing a stress test. Though not perfect diagnostic tests, stress tests are useful when symptoms are present that are doubtful in nature. Gary’s left shoulder ache could have been related to his heart, but the likelihood was that it was not. A stress test would have answered the diagnostic question quite adequately.

Instead, this man was subjected to an invasive test that was likely unnecessary. This happens dozens, if not hundreds, of times per day just around here. Nationwide, it is an epidemic of malpractice.

There are, indeed, times when a person should proceed directly to a heart catheterization. This is commonly and appropriately performed when a person develops unstable heart symptoms, such as chest discomfort or breathlessness at rest while not doing anything physical, or if the frequency is increasing, or if a stress test shows an important abnormality. There is no question that heart procedures can be lifesaving at times.

The problem is that thousands of people every year are scared into these procedures inappropriately. Beware!

Fish oil: The natural triglyceride form is better

2. February 2011 William Davis (43)
If you have a choice, the triglyceride form of fish oil is preferable. The triglyceride form, i.e., 3 omega-3 fatty acids on a glycerol "backbone," is the form found in the body of fish that protects them from cold temperatures (i.e., they remain liquid at low ambient temperatures).

Most fish oils on the market are the ethyl ester form. This means that the omega-3 fatty acids have been removed from the glycerol backbone; the fatty acids are then reacted with ethanol to form the ethyl ester.

If the form is not specified on your fish oil bottle, it is likely ethyl ester, since the triglyceride form is more costly to process and most manufacturers therefore boast about it. Also, prescription Lovaza--nearly 20 times more costly than the most expensive fish oil triglyceride liquid on a milligram for milligram basis--is the ethyl ester form. That's not even factoring in reduced absorption of ethyl esters compared to triglyceride forms. Remember: FDA approval is not necessarily a stamp of superiority. It just means somebody had the money and ambition to pursue FDA approval. Period.

Taking any kind of fish oil, provided it is not overly oxidized (and thereby yields a smelly fish odor), is better than taking none at all. All fish oil will reduce triglycerides, accelerate clearance of postprandial (after-eating) lipoprotein byproducts of a meal (via activation of lipoprotein lipase), enhance endothelial responsiveness, reduce small LDL particles, and provide a physical stabilizing effect on atherosclerotic plaque.

But if you desire enhanced absorption and potentially lower dose to achieve equivalent RBC omega-3 levels, then triglyceride forms are better.

Here are cut-and-pasted abstracts of two of the studies comparing forms of fish oil.

Bioavailability of marine n-3 fatty acid formulations.

Dyerberg J, Madsen P, Moller JM et al. 
Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Copenhagen, Denmark.

Abstract

The use of marine n-3 polyunsaturated fatty acids (n-3 PUFA) as supplements has prompted the development of concentrated formulations to overcome compliance problems. The present study compares three concentrated preparations - ethyl esters, free fatty acids and re-esterified triglycerides - with placebo oil in a double-blinded design, and with fish body oil and cod liver oil in single-blinded arms. Seventy-two volunteers were given approximately 3.3g of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) daily for 2 weeks. Increases in absolute amounts of EPA and DHA in fasting serum triglycerides, cholesterol esters and phospholipids were examined. Bioavailability of EPA+DHA from re-esterified triglycerides was superior (124%) compared with natural fish oil, whereas the bioavailability from ethyl esters was inferior (73%). Free fatty acid bioavailability (91%) did not differ significantly from natural triglycerides. The stereochemistry of fatty acid in acylglycerols did not influence the bioavailability of EPA and DHA.

Abstract

There is a debate currently about whether different chemical forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are absorbed in an identical way. The objective of this study was to investigate the response of the omega-3 index, the percentage of EPA+DHA in red blood cell membranes, to supplementation with two different omega-3 fatty acid (n-3 FA) formulations in humans. The study was conducted as a double-blinded placebo-controlled trial. A total of 150 volunteers was randomly assigned to one of the three groups: (1) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as reesterified triacylglycerides (rTAG group); (2) corn oil (placebo group) or (3) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as ethyl ester (EE group). Volunteers consumed four gelatine-coated soft capsules daily over a period of six months. The omega-3 index was determined at baseline (t(0)) after three months (t(3)) and at the end of the intervention period (t(6)). The omega-3 index increased significantly in both groups treated with n-3 FAs from baseline to t(3) and t(6) (P < 0.001). The omega-3 index increased to a greater extent in the rTAG group than in the EE group (t(3): 186 versus 161% (P < 0.001); t(6): 197 versus 171% (P < 0.01)). Conclusion: A six-month supplementation of identical doses of EPA+DHA led to a faster and higher increase in the omega-3 index when consumed as triacylglycerides than when consumed as ethyl esters.

Diarrhea, asthma, arthritis--What is your wheat re-exposure syndrome?

30. January 2011 William Davis (52)
Have you experienced a wheat re-exposure syndrome?

As I recently discussed, gastrointestinal distress--cramps, gas, diarrhea--is the most common "syndrome" that results from re-exposure to wheat after a period of elimination.

Others experience asthma, sinus congestion and infections, mental "fogginess" and difficulty concentrating, or joint pains and/or overt swelling.

Still others say there is no such thing.

Let's take a poll and find out what readers say.

Marathoners, triathletes, and heart disease

30. January 2011 William Davis (0)
Curious thing: People with lipoprotein(a) gravitate towards elite levels of exercise.

I tell my lipoprotein(a) patients that, if they want to see a lot of other people with lipoprotein(a), go to a marathon or triathlon.

This effect applies more to males than to females, just as the fascination with numbers seems to be confined to men, too. That's why I've posted in past about the "prototypical" lipoprotein(a) male.

I believe this is a big part, perhaps the only, reason why there seems to be a modest increased risk for cardiovascular events despite high exercise levels in marathoners. It has nothing to do with the exercise itself; it has to do with the kind of people who choose to exercise at this level.

The best fish oil

29. January 2011 William Davis (30)
The best fish oils available are the liquid forms. Contrary to many people's expectations, the best liquid fish oils have no fishy odor or taste.

I use a lot of liquid fish oils because of the higher doses we use in the Track Your Plaque program, as well as our strategy of high-dose fish oil to reduce lipoprotein(a). Women, in particular, don't like taking the oodles of capsules required to achieve the higher doses we need. So the ladies really like the liquid forms.

The best liquid fish oils are non-fishy, highly-concentrated, and come in the better absorbed triglyceride form. Many capsules, including prescription Lovaza, are the less well-absorbed ethyl ester form. Several studies, such as this one, have now demonstrated that the naturally-occurring triglyceride form yields higher blood (RBC) levels of omega-3 fatty acids, likely due to more efficient digestion via pancreatic lipase.

While there are many good forms of fish oil and only a few bad, these are the best of the best:

Pharmax
The Pharmax Finest Pure Fish Oil with Essential Oil of Orange contains 1800 mg EPA + DHA per teaspoon. This is the preparation I've been taking.

Nordic Naturals
The Nordic Naturals lemon-flavored ProOmega Liquid contains 2752 mg EPA + DHA per teaspoon, the most concentrated of any fish oil I've seen.

(This list is not exclusive. These are just two brands I've used extensively with good results.)

These highly-concentrated, triglyceride forms are more expensive, due to their concentrated nature. 1 teaspoon Pharmax fish oil, for example, provides an equivalent quantity of omega-3 fatty acids as 6 standard fish oil capsules on a milligram for milligram basis, but more like 8 to 9 capsules when absorption efficiency is factored in. The triglyceride form is also more laborious to manufacture. On our Track Your Plaque Marketplace, our Pharmax 500 ml runs $58.95 list. (500 ml provides 100 teaspoons or 600-capsule equivalent.)

Note that, minus the protection of the capsule, liquid fish oils will oxidize if not refrigerated. So be sure to keep your liquid fish oil in the fridge.

What do Salmonella, E coli, and bread have in common?

28. January 2011 William Davis (22)
Say you happen to eat some chicken fingers contaminated with bacteria because the 19-year old kid behind the counter failed to wash his hands after using the toilet, or because the kitchen is poorly managed with unwashed counters and cutting boards, or because the food is undercooked. You get a bout of diarrhea and cramps, along with a desire to banish chicken from your life.

Here's yet another odd wheat phenomenon: About 30% of people who eliminate wheat from their lives experience an acute food poisoning-like effect on re-exposure. You've been wheat-free for, say, 6 months. You've lost 25 lbs from your wheat belly, you've regained energy, joints feel better. You go to an office party where they're serving some really yummy looking bruschetta. Surely a couple won't hurt! Within a hour, you're getting that awful rumbling and unease that precede the explosion.

The majority of people who experience a wheat re-exposure syndrome will have diarrhea and cramps that can last from hours to days, similar to food poisoning. (Why? Why would a common food trigger a food poisoning-like effect? It happens too fast to attribute to inflammation.) Others experience asthma attacks, joint pains that last 48 hours to a week, mental fogginess, emotional distress, even rage (in males).

Wheat re-exposure in the susceptible provides a tidy demonstration of the effects of this peculiar product of genetic research. So if you are wheat-free but entertain an occasional indulgence, don't be surprised if you have to make a beeline to the toilet.

The world of intermediate carbohydrates

28. January 2011 William Davis (0)
There are clear-cut bad carbohydrates: wheat, oats, cornstarch, and sucrose. (Fructose, too, but in a class of bad all its own.)

Wheat: The worst. Not only does wheat flour increase blood sugar higher than nearly all other carbohydrates, it invites celiac disease, neurologic impairment, mental and emotional effects, addictive (i.e., exorphin) effects, asthma, irritable bowel syndrome, acid reflux, sleepiness, sleep disruption, arthritis . . . just to name a few.

Oats: Yeah, yeah, I know: "Lowers cholesterol." But nobody told you that oats, including slow-cooked oatmeal, causes blood sugar to skyrocket.

Cornstarch: Like wheat, cornstarch flagrantly increases blood sugar.It also stimulates appetite. That's why food manufacturers put it in everything from soups to frozen dinners.

Sucrose: Not only does sucrose create a desire for more food, it is also 50% fructose, the peculiar sugar that makes us fat, increases small LDL particles, increases triglycerides, slows the metabolism of other foods, encourages diabetes, and causes more glycation than any other sugar.

But there are a large world of "other" natural carbohydrates that don't fall into the really bad category. This includes starchy beans like black, kidney, and pinto; rices such as white, brown, and wild; potatoes, including white, red, sweet, and yams; and fruits. It includes "alternative" grains like quinoa, spelt, triticale, amaranth, and barley.

For lack of a better term, I call these "intermediate" carbohydrates. They are not as bad as wheat, etc., but nor are they good. They will still increase blood glucose, small LDL, triglycerides, etc., just not as much as the worst carbohydrates.

The difference is relative. Say we compare the one-hour blood glucose effects of 1 cup of wheat flour product vs. one cup of quinoa. Typical blood sugar after wheat product: 180 mg/dl. Typical blood sugar after quinoa: 160 mg/dl--better but still pretty bad.

Some people are so carb-sensitive that they should avoid even these so-called intermediate carbohydrates. Others can have small indulgences, e.g., 1/2 cup, and not generate high blood sugars.

Heroin, Oxycontin, and a whole wheat bagel

25. January 2011 William Davis (27)
For a substantial proportion of people who remove wheat from their diet, there is a distinct and unpleasant withdrawal syndrome. Here are the comments of Heart Scan Blog reader, Scott, from Texas:

Hello Dr. Davis,

I've been experimenting with diet, converging upon a Paleo type diet, but I keep running into problems. I have isolated the problem to cutting out wheat.

Sugar, rice, fruit, corn, potatoes, etc. are relatively ok to add or remove from the diet, but cutting out wheat in particular brings on a moderate headache with heavy fatigue all day long. This resembles the wheat withdrawal symptoms I found on your blog. As I write this, I'm on day 8 of wheat-free. I consume a fair variety of meat and veggies each day with a moderate amount of white rice for carbs. Perhaps a bowl of corn flakes with milk and half a bar of dark chocolate a day. I've learned from experience over the past 5 months or so that none of these foods affect the withdrawal. It's purely wheat.

My question is, what is the range of times for withdrawal symptoms that you've heard from different people? Has there been anyone who never recovered from the wheat withdrawal symptoms even after many months?

It's very tough to get work done like this, and even though my body and head feel much healthier in general, my sinuses have cleared, don't have to take a big nap after I eat, etc., I don't want to go down a path where this is the way things are going to be forever. 


People who have never experienced wheat withdrawal pooh-pooh the effect. But, for about 30% of people, wheat withdrawal is a real, palpable, and sometimes incapacitating experience.

Beyond removing an exceptionally digestible carbohydrate that yields blood sugar rises higher than nearly any other known food (due to the unique amylopectin structure of wheat-derived carbohydrate), wheat withdrawal is a form of opiate withdrawal, somewhat like stopping heroin, Oxycontin, and other opiates. Stop eating whole wheat toast for breakfast, whole grain sandwiches for lunch, or whole grain pasta for dinner, and the flow of exorphins, i.e., exogenous morphine-like compounds, stops. You experience dysphoria (sadness, unhappiness), mental "fog," inability to concentrate, fatigue, and decreased capacity to exercise. It is milder than withdrawal from prescription opiates. Unlike withdrawal from more powerful opiates like heroine, there are, thankfully, no seizures or hallucinations. There are also no deaths.

In my experience, most people get through with wheat withdrawal in about 5 days. An occasional person will struggle for as long as 4 weeks. Thankfully for Scott, I've never seen it last longer than 4 weeks. (Interestingly, people who survive the withdrawal syndrome are often prone to a peculiar re-exposure phenomenon that I will discuss in future, i.e., they get sick upon re-exposure.)

The modern dwarf mutant variant of Triticum aestivum (that our USDA urges us to eat more of) contains greater proportions of gluten proteins compared to wheat pre-1970; glutens are the source of wheat-derived exorphins.

Incidentally, a drug company should be releasing a drug in the next year that will contain naltrexone, an oral opiate blocking drug, for a weight loss indication. They claim it is a blocker of the "mesolimbic reward system." I say it's a blocker of wheat exorphins.

The five most powerful heart disease prevention strategies

24. January 2011 William Davis (39)
You've seen such lists before: 5 steps to prevent heart disease or some such thing. These lists usually say things like "cut your saturated fat," eat a "balanced diet" (whatever the heck that means), exercise, and don't smoke.

I would offer a different list. You already know that smoking is a supremely idiotic habit, so I won't repeat that. Here are the 5 most important strategies I know of that help you prevent heart disease and heart attack:

1) Eliminate wheat from the diet--Provided you don't do something stupid, like allow M&M's, Coca Cola, and corn chips to dominate your diet, elimination of wheat is an enormously effective means to reduce small LDL particles, reduce triglycerides, increase HDL, reduce inflammatory measures like c-reactive protein, lose weight (inflammation-driving visceral fat), reduce blood sugar, and reduce blood pressure. I know of no other single dietary strategy that packs as much punch. This has become even more true over the past 20 years, ever since the dwarf variant of modern wheat has come to dominate.

2) Achieve a desirable 25-hydroxy vitamin D level--Contrary to the inane comments of the Institute of Medicine, vitamin D supplementation increases HDL, reduces small LDL, normalizes insulin and reduces blood sugar, reduces blood pressure, and exerts potent anti-inflammatory effects on c-reactive protein, matrix metalloproteinase, and other inflammmatory mediators. While we also have drugs that mimic some of these effects, vitamin D does so without side-effects.

3) Supplement omega-3 fatty acids from fish oil--Omega-3 fatty acids reduce triglycerides, accelerate postprandial (after-meal) clearance of lipoprotein byproducts like chylomicron remnants, and have a physical stabilizing effect on atherosclerotic plaque.

4) Normalize thyroid function--Start with obtaining sufficient iodine. Iodine is not optional; it is an essential trace mineral to maintain normal thyroid function, protect the thyroid from the hundreds of thyroid disrupters in our environment (e.g., perchlorates from fertilizer residues in produce), as well as other functions such as anti-bacterial effects. Thyroid dysfunction is epidemic; correction of subtle degrees of hypothyroidism reduces LDL, reduces triglycerides, reduces small LDL, facilitates weight loss, reduces blood pressure, normalizes endothelial responses, and reduces oxidized LDL particles.

5) Make exercise fun--Not just exercise for the sake of exercise, but physical activity or exercise for the sake of having a good time. It's the difference between resigning yourself to 30 minutes of torture and boredom on the treadmill versus engaging in an activity you enjoy and look forward to: go dancing, walk with a friend, organize a paintball tournament outdoors, Zumba class, plant a new garden, etc. It's a distinction that spells the difference between finding every excuse not to do it, compared to making time for it because you enjoy it.

Note what is not on the list: cut your fat, eat more "healthy whole grains," take a cholesterol drug, take aspirin. That's the list you'd follow if you feel your hospital needs your $100,000 contribution, otherwise known as coronary bypass surgery.

Topping up your vitamin D tank

22. January 2011 William Davis (17)
Now that my vitamin D replacement experience dates back nearly 5 years, I've been witnessing an unusual phenomenon:

The longer you take vitamin D, the less you need.

Let me explain. You take 10,000 units D3 in gelcap form. 25-hydroxy vitamin D levels, checked every 6 months, have remained consistently between 60 and 70 ng/ml. Three years into your vitamin D experience and 25-hydroxy vitamin D level rises to 98 ng/ml--an apparent need for less vitamin D.

So we cut your intake from 10,000 units per day to 8000 units per day. Another 25-hydroxy vitamin D level 6 months later: 94 ng/ml. We cut dose again to 6000 units, followed by another 25-hydroxy vitamin D level of 66 ng/ml.

This has now happened in approximately 20% of the people who have been taking vitamin D for 3 or more years. I know of no formal analysis of this effect, what I call the "topping up" phenomenon. Reasoned simply, it seems to me that, once your vitamin D "tank" is topped up (i.e., tissue stores have been replenished), it requires less to keep it full.

No one has experienced any adverse consequence of this topping up effect though it has potential for some people to develop toxic levels if 25-hydroxy vitamin D levels are not monitored long-term. In my office, I measure 25-hydroxy vitamin D levels every 6 months.

It means that long-term monitoring of 25-hydroxy vitamin D is crucial to maintain favorable and safe levels.

Thirteen catheterizations later

21. January 2011 William Davis (16)
When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

It started with chest pains at age 56, prompting her first heart catheterization that uncovered severe atherosclerotic blockages in all three coronary arteries. Her cardiologist advised a bypass operation.

Six months after the bypass operation, Janet was back with more chest pains, just as bad as before. Another heart catherization showed that two of the three bypass grafts had failed. The third bypass graft contained a severe blockage that required a stent, along with multiple stents in the two now unbypassed arteries.

In the ensuing 18 months, Janet returned for 8 additional catheterizations, each time leaving the hospital with one or more stents.

Janet's doctor was puzzled as to why her disease was progressing so aggressively despite Lipitor and the low-fat diet provided by the hospital dietitian. So he had Janet undergo lipoprotein testing (NMR):

LDL particle number: 3363 nmol/L
Small LDL particle number: 2865 nmol/L
HDL cholesterol: 32 mg/dl
Triglycerides: 344 mg/dl
Fasting blood glucose 118 mg/dl
HbA1c 5.8%

Unfortunately, Janet's doctor didn't understand what these values meant. He pretty much threw his arms up in frustration. That's when I met Janet.

From her lipoprotein panel and other values, it was clear to me that Janet was miserably carbohydrate-sensitive and carbohydrate-indulgent, as demonstrated by the extravagant quantity (2865 nmol/L) and proportion (2865/3363, or 85%) of small LDL, the form of LDL particles created by carbohydrate exposure. Janet struggled with depression over the years and had been using carbohydrate foods as "comfort" foods, often resorting to cookies, pies, cakes, breads, and other wheat-containing foods for emotional solace.

It took a bit of persuasion to convince Janet that it was low-fat, "healthy whole grains," as well as comfort foods, that had led her down this path. I also helped Janet correct her severe vitamin D deficiency, mild thyroid dysfunction, and lack of omega-3 fatty acids.

Since meeting Janet and instituting her new prevention program, she has undergone three additional catheterizations (performed by another cardiologist), all performed for chest pain symptoms that struck during periods of emotional stress. All showed . . . no significant blockage. (Apparently, the repeated "need" for stents triggered a Pavlovian response: chest pain = "need" for yet more stents.)

In short, correction of the causes of coronary atherosclerotic plaque--small LDL, vitamin D deficiency, omega-3 fatty acid deficiency, and thyroid dysfunction--and Janet's disease essentially ground to a halt.

Imagine, instead, that Janet had undergone 1) a heart scan to identify hidden coronary plaque 5-10 years before her first heart procedure, then 2) corrected the causes before they triggered symptoms and posed danger. She might have been spared an extraordinary amount of life crises, hospital procedures, expense (nearly $1 million), and emotional suffering.
