The case builds against wheat

Looking back over the past few posts I've made about the adverse health effects of wheat, I was surprised to see just how many people have posted descriptions of their dramatic experiences following this route.

While I've seen it in real life many times, it always helps to have corroboration from others. Here is what a number of Heart Scan Blog readers and commenters have said:

It's true! We've done it. My husband and I stopped eating all grains and sugar in February. At this point, we really don't miss them any more. It was a huge change, but it's worth the effort. I've lost over 20 pounds (10 to go)and my husband has lost 45 pounds (20 to go). On top of it, our body shapes have changed drastically. It is really amazing. I've got my waist back (and a whole wardrobe of clothes) - I'm thrilled.

I'm also very happy to be eating foods that I always loved like eggs, avocados, and meats - without feeling guilty that they're not good for me.

With the extremely hot weather this week in our area, we thought we'd "treat" ourselves to small ice cream cones. To our surprise, it wasn't that much of a treat. Didn't even taste as good as we'd anticipated. I know I would have been much more satisfied with a snack of smoked salmon with fresh dill, capers, chopped onion and drizzled with lemon juice.

Aside from weight changes, we both feel so much better in general - feel much more alert and move around with much greater flexibility, sleep well, never have any indigestion. We're really enjoying this. It's like feeling younger.

It's not a diet for us. This will be the way we eat from now on. Actually, we think our food has become more interesting and varied since giving up all the "white stuff". I guess we felt compelled to get a little more creative.

Eating out (or at other peoples' places) has probably been the hardest part of this adjustment. But now we're getting pretty comfortable saying what we won't eat. I'm starting to enjoy the reactions it produces.



Weight loss, increased energy, less abdominal bloating, better sleep--I've seen it many times, as well.

I was a victim of the '80s lowfat diet craze - doc told me I was obese, gave me the Standard American Diet and said to watch my fat (I'm not a big meat eater, didn't like mayo ... couldn't figure out where my fat was coming from! maybe the fries - I will admit I liked fries). I looked to the USDA food pyramid and to increase my fiber for the constipation I was experiencing. Bread with 3 grams of fiber wasn't good enough; I turned to Kashi cereals for 11 years. My constipation turned to steattorrhea and a celiac disease diagnosis! *No gut pains!* My PCP sent me to the gastroenterologist for a colonscopy because my ferritin was a 5 (20 is low range). Good thing I googled around and asked him to do an endoscopy or I'd be a zombie by now.

My symptoms were depression & anxiety, eczema, GERD, hypothyroidism, mild dizziness, tripping, Alzheimer's-like memory problems, insomnia, heart palpitations, fibromyalgia, worsening eyesight, mild cardiomyopathy, to name a few.

After six months gluten-free, I asked my gastroenterologist about feeling full early ... he said he didn't know what I was talking about! *shrug*

But *I* knew -- it was the gluten/starches! My satiety level has totally changed, and for the first time in my life I feel NORMAL!


Feeling satisfied with less is a prominent effect in my experience, too. You need to eat less, you're driven to snack less, less likely to give in to those evil little bedtime or middle-of-the-night impulses that make you feel ashamed and guilty.



An anonymous (female) commenter said:

My life changed when I cut not only all wheat, but all grains from my diet.

For the first time in my life, I was no longer hungry -no hunger pangs between meals; no overwhelming desire to snack. Now I eat at mealtimes without even thinking about food in between.

I've dropped 70 pounds, effortlessly, come off high blood pressure meds and control my blood sugar without medication.

I don't know whether it was just the elimination of grain, especially wheat, or whether it was a combination of grain elimnation along with a number of other changes, but I do know that mere reduction of grain consumption still left me hungry. It wasn't until I elimnated it that the overwhelming redution in appetite kicked in.

As a former wheat-addicted vegetarian, who thought she was eating healthily according to all the expert advice out there at the time, I can only shake my head at how mistaken I was.


That may be a record for me: 70 lbs!!


Stan said:

It's worth it and you won't look back!

Many things will improve, not just weight reduction: you will think clearer, your reflexes will improve, your breathing rate will go down, your blood pressure will normalize. You will never or rarely have a fever or viral infections like cold or flu. You will become more resistant to cold temperature and you will rarely feel tired, ever!

Whenever I go out to breakfast I look around and I am in shock at what people eat for breakfast. Big stack of pancakes, fruit, fruit juice syrup, just like you said. This is not breakfast, this is dessert ! It has the same sugar and nutrition as a birthday cake, would anyone think cake is ok for breakfast ? No, but that is exactly the equivalent of what they are eating. Somehow we have been duped to think this is ok. For me, I typically eat an omelette when I go out, low carb and no sugar. I dont eat wheat but invariably it comes with the meal and I try to tell the waitress no thanks, they are stunned. They try to push some other type of wheat or sugar product on me instead, finally I have to tell them I dont eat wheat and they are doubly stunned. They cant comprehend it. We have a long way to go in terms of re-education.

Yes. Don't be surprised at the incomprehension, the rolled eyes, even the anger that can sometimes result. Imagine that told you that the food you've come to rely on and love is killing you!


Anne said:

I was overweight by only about 15lbs and I was having pitting edema in my legs and shortness of breath. My cardiologist and I were discussing the possible need of an angiogram. I was three years out from heart bypass surgery.

Before we could schedule the procedure, I tested positive for gluten sensitivity through www.enterolab.com. I eliminated not only wheat but also barley and rye and oats(very contaminated with wheat) from my diet. Within a few weeks my edema was gone, my energy was up and I was no longer short of breath. I lost about 10 lbs. The main reason I gave up gluten was to see if I could stop the progression of my peripheral neuropathy. Getting off wheat and other gluten grains has given me back my life. I have been gluten free for 4 years and feel younger than I have in many years.

There are many gluten free processed foods, but I have found I feel my best when I stick with whole foods.



Ann has a different reason (gluten enteropathy, or celiac disease) for wanting to be wheat-free. But I've seen similar improvements that go beyond just relief of the symptoms attributable to the inflammatory intestinal effects of gluten elimination.

I have relatively successfully cut carbs and grains from my diet thus far.

Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

I have also been very surprised at the significant reduction in my appetite. I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too. But it has.

A few weeks ago, I attended a party catered by one of my favorite italian restaurants and got myself offtrack for two days. Then it took me a couple of days to get back on track because my appetite returned.

Check out Jimmy Moore's website for lots of ideas about variations of foods to try. The latest thing I picked up from Jimmy is the good old-fashioned hard boiled egg. Two or three eggs with some spicy hot sauce for breakfast and a handful of almonds mid-morning plus a couple glasses of water and I'm good for the morning no problem.

I find myself thinking about lunch not because I'm really hungry but out of habit.

The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.



Going wheat-free, along with a reduction in processed sugary foods like Hawaiian Punch, sodas, and candy, is the straightest, most direct path I know of to lose weight, obtain all the health benefits listed by our commenters, as well as achieve the lipoprotein corrections we seek, like reduction of small LDL particles and rise in HDL, in the Track Your Plaque program.

Cheers to flavonoids

The case in favor of healthful flavonoids seems to grow bit by bit.

Flavonoids such as procyanadins in wine and chocolate, catechins in tea, and those in walnuts, pomegranates, and pycnogenol (pine bark extract) are suspected to block oxidation of LDL (preventing its entry into plaque), normalize abnormal endothelial constriction, and yield platelet-blocking effects (preventing blood clots).

Dr. Roger Corder is a prolific author of many scientific papers detailing his research into the flavonoids of foods, but wine in particular. He summarizes his findings in a recent book, The Red Wine Diet. Contrary to the obvious vying-for-prime-time title, Dr. Corder's compilation is probably the best discussion of flavonoids in foods and wines that I've come across. Although it would have been more entertaining if peppered with more wit and humans interest, given the topic, its straightfoward, semi-academic telling of the story makes his points effectively.

Among the important observations Corder makes is that regions of the world with the greatest longevity also correspond to regions with the highest procyanidin flavonoids in their wines.




Regading the variable flavonoid content of various wines, he states:

Although differences in the amount of procyanidins in red wine clearly occur because of the grape variety and the vineyard environment, the winemaker holds the key to what ends up in the bottle. The most important aspect of the winemaking process for ensuring high procyanidins in red wines is the contact time between the liquid and the grape seeds during fermentation when the alcohol concentration reaches about 6 percent. Depending on the fermentation temperature, it may be two to three days or more before this extraction process starts. Grape skins float and seeds sink, so the number of times they are pushed down and stirred into the fermenting wine also increases extraction of procyanidins. Even so, extraction is a slow process and, after fermentation is complete, many red wines are left to macerate with their seeds and skins for days or even weeks in order to extract all the color, flavor, and tannins. Wines that have a contact time of less than seven days will have a relatively low level of procyanidins. Wines with a contact time of ten to fourteen days have decent levels, and those with contact times of three weeks or more have the highest.

He points out that deeply-colored reds are more likely to be richer in procyanidins; mass-produced wines that are usually "house-grade" served at bars and restaurants tend to be low. Some are close to zero.

Wines rich in procyanidins provide several-fold more, such that a single glass can provide the same purported health benefit as several glasses of a procyanidin-poor wine.

So how do various wines stack up in procyanidin content? Here's an abbreviated list from his book:

Australian--tend to be low, except for Australian Cabernet Sauvignon which is moderate.

Chile--only Cabernet Sauvignon stands out, then only moderate in content.

France--Where to start? The French, of course, are the perennial masters of wine, and prolonged contact with skins and seeds is usually taken for granted in many varieties of wine. Each wine region (French wines are generally designated by region, not by variety of grape) can also vary widely in flavonoid content. Nonetheless, Bordeaux rate moderately; Burgundy low to moderate (except the village of Pommard); Languedoc-Roussillon moderate to high (and many great bargains in my experience, since these producers live in the shadow of its norther Bordeaux neighbors); Rhone (Cote du Rhone) moderate to high, though beware of their powerful "barnyard" character upon opening; decanting is wise.

Italy--Much red Italian wine is made from the Sangiovese grape and called variously Chianti, Valpolicella, and "super-Tuscan" when blended with other varietals. Corder rates the southern Italian wines from Sicily, Sardinia, and the mainland as high in procyanidins; most northern varieties are moderate.

Spain--Moderate in general.

United States--Though his comments are disappointingly scanty on the U.S., he points out that Cabernet Sauvignon is the standout for procyanidin content. He mentions only the Napa/Sonoma regions, unfortunately. (I'd like to know how the San Diego-Temecula and Virginian wines fare, for instance.)

The winner in procyanidin content is a variety grown in the Gers region of southwest France, a region with superior longevity of its residents. The wines here are made with the tannat grape within the Madiran appellation; wines labeled "Madiran" must contain 40% or more tannat to be so labeled (such is a quirk of French wine regulation). However, among the producers Dr. Corder lists are Chateau de Sabazan, CHateau Saint-Go, Chateau du Bascou, Domaine Labranche Laffont, and Chateau d'Aydie. (A more complete can be found in his book.)

How does this all figure into the Track Your Plaque program? Can you succeed without red wine? Of course you can. I doubt you could do it, however, without some attention to flavonoid-rich food sources, whether they come from spinach, tea, chocolate, beets, pomegranates, or red wine.

Though my wife and I love wine, I confess that I've never personally drank or even seen a French Madiran wine. Any wine afficionados with some advice?

Wheat and the hunger factor

Low carbohydrate diets are becoming increasingly popular. In my experience, they also work exceptionally well.

However, I have observed a specific aspect of low-carb diets that deserves special attention: When wheat products in particular are eliminated, hunger plummets enormously.

It seems peculiar to wheat. Other high-glycemic index carbohydrates like a baked potato or white rice, for instance, don't seem to have the capacity to trigger appetite like a handful of pretzels or crackers can. There are exceptions: processed sweet drinks that contain high-fructose corn syrup can stimulate appetite, as do foods made with processed corn and corn starch.



However, wheat has grown to occupy an enormous part of diet, partly because of the "high-fiber" trickery that causes us to believe that wheat is healthy, but also, I'm convinced, because of wheat's hunger factor.


A reader of the The Heart Scan Blog recently made this comment:

I discovered this blog and Dr. Davis' TYP program at the beginning of September. I have relatively successfully cut carbs and grains from my diet thus far.

Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

I have also been very surprised at the significant reduction in my appetite. I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too. But it has.

A few weeks ago, I attended a party catered by one of my favorite Italian restaurants and got myself offtrack for two days. Then it took me a couple of days to get back on track because my appetite returned.

The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.



I, too, have personally experienced this effect. I also was skeptical. It made no sense. How can whole grain bread increase appetite? I don't know what it is about wheat products that make them especially powerful triggers of appetite. I think that it probably goes beyond glycemic index, perhaps some other component besides taste.

But if you want to seize control over appetite, elimination--not reduction--but elimination of wheat, as well as other processed carbohydrates, can really change the way you approach food. (Interestingly, The Wheat Foods Council estimates that the average American eats 144 lbs of wheat flour per year; they argue that it should be increased 210 lbs per year!)

Eliminating wheat products is also an effective tool in the Track Your Plaque program for raising HDL, reducing triglycerides, reducing small LDL, and reducing both blood sugar and blood pressure. And it can be among the most effective ways to control appetite, since eliminating wheat also eliminates its hunger factor.

Foods to consider to take up the calorie slack when eliminating wheat: cheese (fermented, of course, for vitamin K2 content); eggs, as our reader pointed out; other lean proteins like lean red meats, fish, chicken, turkey; more liberal use of healthy oils like olive and flaxseed; plenty of raw nuts and seeds; soy milk and tofu. Obviously, the center of your diet should remain vegetables.

Our friends at Liposcience

A number of Track Your Plaque Members are still outraged at LabCorp's failure to convey the results of page 2 of the NMR Lipoprofile, as provided by Liposcience, Inc., the testing laboratory that actually performs the test. We've gotten an audience at both Liposcience and LabCorp, though no real progress in obtaining this information has yet been made.

Anyway, that's not what I'd like to focus on. Despite the tremendous aggravation created by this incomprehensible glitch, NMR Lipoprofile remains, in my view, the best way to discover hidden sources of risk for heart disease and the most powerful way to develop a coronary plaque/heart scan score control program.

We could do without NMR, but I think that we'd pay a price in effectiveness. We'd be, in effect, driving blindly when it comes to certain lipoprotein patterns. Some abnormalities, like intermediate-density lipoprotein (IDL) and LDL particle number, are superior to similar measures (like apoprotein B and direct LDL) and yield priceless information that is simply not obtainable as reliably by any other method.

I've had my share of negative experiences with the marketing director and the staff at Liposcience, but it's the vision of company founder and inventor of the technology, biochemist Dr. James Otvos, that should continue to shine. Dr. Otvos' ingenious technology to fractionate plasma proteins has provided an advantage for coronary plaque reversal and reduction of CT heart scan scores that no other method can provide as well.

For a useful discussion on basic lipoprotein science, listen to the discussion provided by Dr. William Cromwell of Liposcience by clicking on the graphic below:

Condensed Taubes

For anyone looking for a quick glimpse at Gary Taubes' provocative arguments on the detrimental health effects of the current carbohydrate-crazed world, take a look at the CNN post of an interview of Taubes at CNN. (Thanks, Fanatic Cook, for pointing this out.)

In his book, Good Calories, Bad Calories, Taubes, a science reporter, manages to deftly and systematically disarticulate the entire argument for the low-fat approach to nutrition that has dominated conventional advice for the last 30+ years.

The book is impressively detailed and well-thought through. If you would like an introduction to the nutrition world according to Taubes, take a look at the CNN video, which permits him to provide a quick, condensed version of his ideas. Even when debating the issue with physicians, Taubes' arguments shine through as a voice of reason, cutting through the flabby and tired arguments that have been proven misguided by the experience of those around us.

Fast-forward information

The internet has accelerated the conversation in health . . . enormously.

The discussions we have in Blogs, places like the Track Your Plaque Forum, and websites have accelerated the exchange of information and ideas so much that it is making traditional "official" sources of information IRRELEVANT.

Dr. John Cannell's unfailingly interesting and insightful comments in his most recent Vitamin D Newsletter brought this issue to mind. In his discussion of the vitamin D needs of pregnant women and his frustration with the failure of the National Institute of Health to take action despite the evidence, he states:

Whenever you see a child with asthma, diabetes or autism, just think: American Medical Association, American Pediatric Association, Institute of Medicine, Centers for Disease Control, National Institutes of Health, or Food and Nutrition Board.

Dr. Cannell is upset with the misguided advice of these agencies for mothers and babies to totally avoid sun while failing to provide advice on vitamin D supplementation, a combination of unhealthy factors that will increase the incidence of both type I and II diabetes, childhood asthma, and perhaps even childhood autism.

But this got me thinking: Here we are listening to a very credible source in Dr. Cannell, who has proven a discriminating judge of the evidence, along with vitamin D experts like Tufts University's Dr. Michael Holick, who has written a book on vitamin D (The UV Advantage: The Medical Breakthrough that Shows How to Harness the Power of the Sun for Your Health) ; University of Toronto's Dr. Reinhold Vieth, whose wonderful webcast on vitamin D was certain to convince you of many aspects of this nutrient's vital importance in health (unfortunately, it must have been taken off the hosting server, since I can no longer locate it); among others.

We all have access to this information. They are providing discussions on the topic that have long ago made the comments of "official" agencies like the FDA or the Institute of Medicine's Food and Nutrition Board (charged with setting RDA's for vitamins) irrelevant. While information is conveyed at lightning speed through internet media sources, discussion boards, and chats, the committees of "experts" often sit on their hands, fearful of speaking out, often themselves unfamiliar with the scientific literature or the conversations being conducted, not uncommonly having hidden agendas of their own that might interfere with their impartiality.

Information on health (and other subjects, as well) is being conveyed to the interested public faster and faster. The FDA, the USDA, the Food and Nutrition Board, the American Heart Association are increasingly being viewed as behind the times. They often also provide tainted information. Among the most glaring examples of biased information is the Heart Association's endorsement of "heart healthy" products in its Heart Check Mark program, including Cocoa Puffs, Cookie Crisp cereal, and Berry Kix, pure unadulterated junk foods thinly veiled with the Heart Association stamp of approval. Or the American Diabetes Association failure to speak out on the increasing penetration of carbohydrate and sugary junk foods in the American diet, while maintaining relationships and funding from its number one financial contributor, Cadbury Schweppes, the number one candy, soft drink, and snack manufacturer in the world.

The collective knowledge we are gaining through our own efforts will supplant the mis-information provided by official agencies. Just as Wikipedia represents collective knowledge on a broad range of topics, such a collective wisdom will develop in health, as well.

America: The world’s diet laboratory

Low-fat, low-carb, high-protein, Pritikin, Ornish, Atkins, South Beach, Sonoma, Sugar-Busters, Weight Watchers, vegetarian . . . Have Americans tried them all?

We’ve witnessed the relative success of diet habits in selected regions world-wide: the longevity of the Japanese on a spare soy and fish-based diet; the reduced heart disease incidence of the French despite an indulgent food-centered culture; the extreme heart disease-free lives of the Cretan Greeks.

Contrast this with the startling failure of the American diet experiment: We’re all (speaking for the collective whole) fat, diabetic, and miserably mired in the diseases of obesity. We’ve experimented with every possible iteration of diet from grapefruit or cabbage only, to calorie deprivation (a al Weight Watchers), to restricting this or that element of diet. The “official” organizations have made their contributions, as well: the American Heart Association’s Therapeutic Lifestyle Changes (formerly Step I and II diets), a program eerily similar to what Americans are already eating and resulting in failure; the American Diabetes Association diet, incomprehensibly embracing carbohydrates when they are the root of the nutrition-habit-gone-wrong that caused the disease in the first place; the USDA and their Food Pyramid, encompassing a design that contains the germ of wisdom but is so heavily overweighted in grains that it is a sure-fire way to increase weight and heart disease were you to follow their recommendations.

What have we learned from our grand experiment, our nationwide misadventure in nutrition?

I believe that we’ve learned how not to eat: Processed snack foods, meals delivered in a fast-food setting with the offer to “super-size” your order, make-believe food ingested in your car eaten for the sake of staving off the inevitable hunger pangs. Few would argue that these are certain paths to obesity and poor health.

Certainly, if we’ve learned how not to eat, can we extrapolate just how to eat? And not just for weight loss, since most diets focus just on that, but on health, particularly heart health?

If Americans have so far failed to learn the lessons of the nutritional world, we certainly have not failed at talking about it. From books to blogs, websites, information gurus to infomercials, we certainly celebrate the capacity to share our experiences, our grief over our nutritional “misfortune,” despite a world of plenty.

Yet we swim in a sea of information. Can we sift through the chaff to discover the essential truth?

Let me articulate an extreme (extreme meaning closer to the truth, I hope) interpretation of nutritional wisdom:

--If it requires a label or nutritional analysis, reject it. The wondrous green pepper, or bottle of olive oil, for instance, require no such qualifications. Some exceptions: milk, yogurt, cottage cheese (unless, of course, you purchase straight from a local producer). I am always impressed with the contortions and frustrations people experience trying to decipher labels. Ironically, the healthiest foods don’t even require labels.

--If it is ingested in a rush, it’s likely to add to poor health. True food is meant to be consumed at leisure, not in haste to satisfy some irrational, unthinking impulse.

--Search for natural, whole foods. Natural, whole foods require no marketing. You pay a premium for a company to adorn a product with glitz, glamour, and appeal. Repackage Cocoa Puffs as chocolate flavored, round overly-processed wheat flour, sans marketing spin, and what is left? Processed foods are?intentionally?addictive. They are added to, modified, high-fructose corn syruped, etc. to increase desirability, but also create addiction. Eliminate them just as a smoker eliminates cigarettes.

--A corollary to the above issue: purchase foods that appear as if you had grown it or raised it yourself. If you were to grow corn in your backyard garden, you would eat it on the cob or some similar way. You would not grind it, pulverize, process it, nor serve it as cornstarch and add to a pile of chemicals to make breakfast cereal. Eat foods in their natural state, not the highly processed food-product that requires a colorful package and advertising to sell.

--Don’t keep bags of chips, boxes of breakfast cereal and crackers, frozen dinners, all “just in case.” Don’t allow yourself that opportunity because you will more than likely seize it. An alcoholic who keeps a secret bottle of gin hidden in the cabinet is well aware that it’s there and will eventually give in to impulse.

--When you eat meat, try to find free-range, organic products. Even better, purchase from a local producer who you trust.

--For anyone with patterns like low HDL, small LDL, high triglycerides, and blood sugar >100 mg/dl, following a diet that is as free of wheat products as possible will yield enormous benefits. Wheat is a part of all breads, virtually all breakfast cereals, pretzels, crackers, bagels, cookies, cupcakes, pancakes, waffles, etc. Going wheat-free is also a surprisingly effective weight loss strategy.

That’s just a few thoughts. The approach we use in the Track Your Plaque program helps achieve weight loss, but also helps correct lipoprotein patterns, often dramatically.

Many diets have failed to keep pace with the changing nutritional habits of Americans. In 1960, we ingested close to zero high-fructose corn syrup. We’re now approaching 80 lbs per year per American. Breakfast cereal in 1950 consisted of a handful of products, eaten intermittently; today, it is a staple with enough products to fill a modern supermarket’s entire aisle. Meats have changed, thanks to the factory farm phenomenon feeding its animals corn in inhumanely restricted conditions, a dietary shift for livestock that has modified the fat composition to something far different than 50 years ago, not to mention the antibiotics and other chemicals used to accelerate growth and fight off infection from the artificial, overcrowded conditions.

The American nutritional shift, along with rampant obesity, have also caused a relatively new cause of coronary heart disease to explode: small LDL particles. The contribution of small LDL has been enormously underestimated, since most physicians don’t know what it is, don’t know how to check for it, and don’t know what to do with it. Yet it has emerged as the number one cause for heart attack and heart disease nationwide.

Stay tuned for our rewritten New Track Your Plaque diet to be released as a Special Report on the www.cureality.com website in future.

Dr. Jarvik, is niacin as bad as it sounds?

A popular health newsletter, Everyday Health, carried this headline:

A Cholesterol-Busting Vitamin?

Did you know that niacin, one of the B vitamins, is also a potent cholesterol fighter?
Find out how niacin can help reduce choleseterol.


At doses way above the Recommended Dietary Allowance — say 1,000–2,500 mg a day (1–2.5 grams) — crystalline nicotinic acid acts as a drug instead of a vitamin. It can reduce total cholesterol levels by up to 25%, lowering LDL and raising HDL levels, and can rapidly lower the blood level of triglycerides. It does so by reducing the liver’s production of VLDL, which is ordinarily converted into LDL.


I'd agree with that, except that it is rare to require doses higher than 1000-1500 mg per day unless you are treating lipoprotein(a) and using niacin as a tool for dramatic drops in LDL. But for just raising HDL, shifting HDL into the healthy large class, reducing small LDL, and for reduction of heart attack risk, 1000-1500 mg is usually sufficient; taking more yields little or no further effect.

But after that positive comment comes this:

Niacin is safe — except in people with chronic liver disease or certain other conditions, including diabetes and peptic ulcer. . . However, it has numerous side effects. It can cause rashes and aggravate gout, diabetes, or peptic ulcers. Early in therapy, it can cause facial flushing for several minutes soon after a dose, although this response often stops after about two weeks of therapy and can be reduced by taking aspirin or ibuprofen half an hour before taking the niacin. A sustained-release preparation of niacin (Niaspan) appears to have fewer side effects, but may cause more liver function abnormalities, especially when combined with a statin.


Strange. After a headline clearly designed to pull readers in, clearly stating niacin's benefits, the article then proceeds to scare the pants off you with side-effects.

But look to the side and above the text: Ah . . . two prominent advertisements for Lipitor, complete with Dr. Robert Jarvik's photo. "I've studied the human heart for a lifetime. I trust Lipitor to keep my heart healthy."

Niacin bad. Lipitor good. Even celebrity doc says so. Sounds like bait and switch to me. "You could try niacin--if you dare. But you could also try Lipitor."

Who is Dr. Jarvik, anyway, that he serves as spokesman (or at least figurehead) for this $13 billion dollar a year drug? Of course, he is the 1982 inventor of the Jarvik artificial heart, surely an admirable accomplishment. But does that qualify him to speak about heart disease prevention and cholesterol drugs?

Jarvik has never--never--actually prescribed Lipitor, since he never completed any formal medical training beyond obtaining his Medical Doctor degree, nor has he ever had a license to practice medicine. He does, however, continue in his effort to provide artificial heart devices, principally for implantation as a "bridge" to transplantation, i.e., to sustain a patient temporarily who is dying of end-stage heart failure.

So where does his expertise in heart disease prevention come from? It's beyond me. Perhaps it was the thousands of dollars likely paid to him. That will make an "expert" out of just about anybody.

Robert Bazell, science reporter, for CNBC, made this report on the Jarvik-Lipitor connection in his March, 2007 report, Is this celebrity doctor's TV ad right for you?

Mr. Bazell writes:

On May 16, 1988, an editorial in the New York Times dubbed the artificial heart experiments, “The Dracula of Medical Technology.”

“The crude machines,” it continued, “with their noisy pumps, simply wore out the human body and spirit.”

Since then, in a series of start-up companies, Jarvik has continued his quest to make an artificial heart — as have several other firms. One competitor recently won FDA approval to sell its device for implantation in extreme emergencies.

Perhaps Jarvik’s chances of success with another artificial heart account for his willingness to serve as pitchman for Pfizer. I inquired, without success, to find the going rate for a semi- celebrity like Jarvik to appear in such ads. Thomaselli of Advertising Age said whatever it is, it is “infinitesimal” compared to Pfizer’s expenditures of $11 billion a year on advertising, much of it for Lipitor.

Why spend so much marketing Lipitor?

Because Lipitor is only one of six drugs in the class called statins that lower cholesterol. Many cardiologists say that for the vast majority of people any one of these drugs works just as well as the other. Two of them, Mevacor and Zocor, have already lost their patent protection so they cost pennies a day compared to $3 or more a day for Lipitor.

In 2010, when Lipitor loses its patent protection, it, too, will cost pennies a day, and Pfizer will no longer need Dr. Robert Jarvik.



So, is niacin so bad after all? Or is this Everyday Health report just another clever piece of advertising for Pfizer?

Is niacin as bad as it sounds?

It does so by reducing the liver’s production of VLDL, which is ordinarily converted into LDL.


I'd agree with that, except that it is rare to require doses higher than 1000-1500 mg per day unless you are treating lipoprotein(a) and using niacin as a tool for dramatic drops in LDL. But for just raising HDL, shifting HDL into the healthy large class, reducing small LDL, and for reduction of heart attack risk, 1000-1500 mg is usually sufficient; taking more yields little or no further effect.

But after that positive comment comes this:

Niacin is safe — except in people with chronic liver disease or certain other conditions, including diabetes and peptic ulcer. . . However, it has numerous side effects. It can cause rashes and aggravate gout, diabetes, or peptic ulcers. Early in therapy, it can cause facial flushing for several minutes soon after a dose, although this response often stops after about two weeks of therapy and can be reduced by taking aspirin or ibuprofen half an hour before taking the niacin. A sustained-release preparation of niacin (Niaspan) appears to have fewer side effects, but may cause more liver function abnormalities, especially when combined with a statin.


Strange. After a headline clearly designed to pull readers in, clearly stating niacin's benefits, the article then proceeds to share the pants off you with side-effects.

But look to the side and above the text: Ah . . . two prominent advertisements for Lipitor, complete with Dr. Robert Jarvik's photo. "I've studied the human heart for a lifetime. I trust Lipitor to keep my heart healthy."

Sounds like bait and switch to me. "You could try niacin--if you dare. But you could also try Lipitor."

Who is Dr. Jarvik, anyway, that he stands as the spokesman (or at least figurehead) for this $13 billion dollar a year drug. Of course, he is the 1982 inventor of the Jarvik artificial heart, surely an admirable accomplishment. But does that qualify him to speak about heart disease prevention and cholesterol drugs? Jarvik has, never actually prescribed Lipitor, since he never completed any formal medical training beyond obtaining his Medical Doctor degree, nor has he ever had a license to practice medicine. He does, however, continue in his effort to provide artificial heart devices, principally for implantation as a "bridge" to transplantation, i.e., to sustain a patient temporarily who is dying of end-stage heart failure.

So where does his expertise in heart disease prevention come from?

Omega-3 fatty acids: Frequency vs. quantity

I believe I have been observing an unexpected phenomenon: When it comes to fish oil and omega-3 fatty acids, the frequency of dosing may be as important, perhaps more important, than the actual dose.

First of all, why advocate omega-3 fatty acids from fish oil? There’s a list of lipid/lipoprotein reasons, including reduction of triglycerides and triglyceride-containing particles (VLDL, intermediate-density lipoproteins), reduction of small LDL, and increase in HDL. There’s also solid benefit in reduction of heart attack risk, reduction in death from heart attack, and reduction in stroke. There are also anti-inflammatory benefits and improvements in mood, reduction in depression.

Fish oil is a crucial ingredient in the Track Your Plaque program. I am honestly uncertain of just how much success we would give up if fish oil were NOT a part of the program, but I am unwilling to find out. The data are simply too compelling to not include omega-3 fatty acids from fish oil. Of course, supplementation of omega-3 fatty acids assumes greater importance in a modern world in which your food has become terribly depleted of the omega-3 fraction of oils. (Cultures that rely heavily on fish or wild game probably would not benefit to the same extent, since these foods contain omega-3 fatty acids.)

But I believe I have observed a curious effect over the past year or two. With the proliferation of many different preparations of fish oil that provide seemingly endless choices—low-potency fish oil, high-potency fish oil, paste forms of fish oil like Coromega, liquids such as Carlson’s, etc.¾I’ve observed that frequency of dosing may exert as much of an effect as the dose.

For example, someone might take the basic, low-potency preparation like Sam’s Club that contains 180 mg EPA and 120 mg DHA per capsule, four capsules per day. That yields a total of 1200 mg EPA and DHA per day. This is our minimum dose that provides the basic heart attack-reducing effect, though with modest effect on triglycerides and associated patterns.

Say someone switches to a high-potency preparation of 360 mg EPA and 240 mg DHA, providing a total of 600 mg omega-3 fatty acids per capsule, or twice the dose of the low-potency preparation. Would you expect double the effect?

Curiously, no. What I have observed, however, is that more frequent dosing may provide a larger effect. The least effective dosing is once per day; twice per day is far more effective. Three times per day¾though cumbersome¾provides even greater effect.

So, which is more important: dose or frequency?

I can’t say for certain, since my observations are informal and have not been obtained by a formal statistical analysis of our data. That will come with time.

For the present, suffice it to say that, if you are struggling with suppression of patterns like increased triglycerides, IDL, or low HDL, then at least twice- or three-times-per-day dosing might be worth considering, even before you increase the dose further.

Best: Greater dose, or higher-potency preparation, combined with higher frequency.

The “Heart Healthy” scam

Like many scams, this one follows a predictable formula.

It is a formula widely practiced among food manufacturers, ever since food products began to jockey for position based on nutritional composition and purported health benefits.

First, identify a component of food, such as wheat fiber or oat bran, that confers a health benefit. Then, validate the healthy effect in clinical studies. Wheat fiber, for instance, promotes bowel regularity and reduces the likelihood of colon cancer. Oat bran reduces blood cholesterol levels.

Second, commercialize food products that contain the purported healthy ingredient. Wheat bran becomes Shredded Wheat, Fiber One, and Raisin Bran cereals and an endless choice of “healthy” breads. Oat bran becomes Honey Bunches of Oats, Quaker’s Instant Oatmeal, and granola bars. Even if many unhealthy components are added, as long as the original healthy product is included, the manufacturer continues to lay claim to healthy effects.

Third, as long as the original healthy ingredient remains, get an agency like the American Heart Association to provide an endorsement: “American Heart Association Tested and Approved.”

The last step is the easiest: just pay for it, provided the product meets a set of requirements, no matter how lax.

You will find the American Heart Association certification on Quaker Instant Oatmeal Crunch Apples and Cinnamon. Each serving contains 39 grams carbohydrate, 16 grams sugar (approximately 4 teaspoons), and 2.5 grams fat of which 0.5 grams are saturated. Ingredients include sugar, corn syrup, flaked corn, and partially hydrogenated cottonseed oil. Curiously, of the 4 grams of fiber per serving, only 1 gram is the soluble variety, the sort that reduces cholesterol blood levels. (This relatively trivial quantity of soluble fiber is unlikely to impact significantly on cholesterol levels, since a minimum 3 grams of soluble fiber is the quantity required, as demonstrated in a number of clinical studies.) Nonetheless, this sugar product proudly wears the AHA endorsement.

Thus, a simple component of food that provides genuine benefit mushrooms into a cornucopia of new products with added ingredients: sugar, high fructose corn syrup, corn starch, carageenan, raisins, wheat flour, preservatives, hydrogenated oils, etc. What may have begun as a health benefit can quickly deteriorate into something that is patently unhealthy.

There’s a clever variation on this formula. Rather than developing products that include a healthy component, create products that simply lack an unhealthy ingredient, such as saturated or trans fats or sodium.

Thus, a ¾-cup serving of Cocoa Puffs cereal contains 120 calories, no fiber, 14 grams (3 ½ teaspoons) of sugar—but is low in fat and contains no saturated fat. Proudly displayed on the box front is an American Heart Association stamp of approval. It earned this stamp of approval because Cocoa Puffs was low in saturated, trans, and total fat and sodium. Likewise, Cookie Crisp cereal, featuring Chip the Wolf, a cartoon wolf in a red sweater (“The great taste of chocolate chip cookies and milk!”), has 160 calories, 26 grams carbohydrate and 19 grams (4½ teaspoons) of sugar per cup, and 0 grams fiber—but only 1.0 gram fat, none saturated, thus the AHA check mark. (Promise margarine, made with hydrogenated vegetable oil and therefore containing significant quantities of trans fats, was originally on the list, as well, but removed when the trans fat threshold was added to the AHA criteria.)

It is this phenomenon, the sleight of hand of taking a healthy component and tacking on a list of ingredients manageable only by food scientists, or asserting that a product is healthy just because it lacks a specific undesirable ingredient, that is a major factor in the extraordinary and unprecedented boom in obesity in the U.S. Imagine the chemical industry were permitted such latitude: “Our pesticide is deemed safe by the USDA because it contains no PCBs.” Such is the ill-conceived logic of the AHA Heart-Check program the "Heart Healthy" claims.

It’s best we keep in mind the observations of New York University nutritionist and author of the book, Food Politics, Marion Nestle, that “food companies—just like companies that sell cigarettes, pharmaceuticals, or any other commodity—routinely place the needs of stock holders over considerations of public health. Food companies will make and market any product that sells, regardless of its nutritional value or its effect on health. In this regard, food companies hardly differ from cigarette companies. They lobby Congress to eliminate regulations perceived as unfavorable; they press federal regulatory agencies not to enforce such regulations; and when they don’t like regulatory decisions, they file lawsuits. Like cigarette companies, food companies co-opt food and nutrition experts by supporting professional organizations and research, and they expand sales by marketing directly to children, members of minority groups, and people in develop countries—whether or not the products are likely to improve people’s diets.”

Qualms over just how heart-healthy their products are? Doubtful.

Exploitation of trust

Once upon a time, the tobacco industry was guilty of conducting a widespread, systematic, highly organized campaign to deliver their product to as much of the unsuspecting public as possible.

As clinical data mounted linking smoking and health problems like cancer and heart disease, tobacco producers labored fiercely to counter these claims despite darkening public sentiment. When individual company executives were questioned on why they continued to perpetuate the industry’s scandalous practices, the invariable justification offered was “Well, I had to pay my mortgage.” That tidy ends-justifies-the-means rationalization has a familiar ring when you examine the behavior of those in the heart "industry."

Things are not what they seem. The hospital, once an institution to serve the sick, a place for clergy, volunteers, and other altruists, has evolved into a business serving a thriving bottom line. You are the “product” they seek. The cardiologist, ostensibly in the service of alleviating heart disease, instead seeks to grow his checkbook by performing procedures that have nothing to do with lessening the burden of heart disease. He dives into the water to save drowning victim after drowning victim, but fails to simply toss in the life preserver that has been close at hand all along.

The woeful family practitioner, who is expected to bear undue responsibility for the broad spectrum of health, ignorantly permits heart disease to grow under his or her nose and, by default, allows heart disease to become the exclusive province of the proceduralist. Worse, the family practitioner or internist in the employ of the hospital (a situation that has quietly grown to encompass 80% of all primary care physicians) labors to fatten hospital business by directing patients into hospital services. The comparative lowly incomes of the primary care physician are substantially supplemented by participating in this huge revenue-generating machine called heart care.

The astounding grasp of the system has caused one of every 10 adults in the U.S. to have undergone a heart procedure. The lemming-like procession to the hospital creates a crowd mentality among some sectors of the frightened public. “My friends and neighbors have all had bypass operations. Sooner or later I guess it’s going to be my turn.”

Tragically, the system has grown through the exploitation of trust. The faith we have in doctors, hospitals, and the institutions and people associated with healthcare has been subverted into the service of profit. Many practitioners and institutions choose to operate under the guise of doing good, but instead capitalize on the public’s willingness to accept as fact the need for major heart procedures and all its associated costly trappings.

Bait and switch

"When banks compete, you win.”

The TV ad opens with a 60-something man sitting in his living room, talking to a three-piece suit-clad, 30-something banker. The older man is explaining to the dismayed younger man why he’s going to use Lending Tree loan service for a home loan.

“But Dad, I’m you’re son!” the younger whines.

Many of Lending Tree’s clients have collaborated in filing a multi-million dollar class action suit against the company, claiming “bait and switch” tactics. They claim that home buyers are lured by low interest rates or low closing costs on a home loan. Once the buyer concludes the hassle of filling out numerous forms, the suit accuses Lending Tree of making a switch to a costlier loan.

Bait and switch is among the oldest con games around. If you’ve ever bought a car from a car dealer, chances are you’ve had your own little brush with this deception. The ad promises the SUV you’ve wanted for only $299 per month. Only, once you get there, the salesman informs you that only a limited number of special deals were available and they’ve run out. But he’s still got a really good deal right over here!

Most of us recognize that we’ve been hookwinked. Yet we still go along and buy a car from the dealer.

What if it’s not a sleazy salesman behind the pitch, but a physician. If it’s hard to resist the sales pitch at the car dealership, it can be near impossible to ignore the advice of your doctor. But the truth is often loud and clear: in many instances, it is a genuine, bona fide, and fully-certified scam.

Among the most common bait-and-switch heart scams: Your cholesterol is high. The sequence of subsequent testing is well-rehearsed. “Gee, Bob, I’m worried about your risk for heart disease. Let’s schedule you for a nuclear stress test.”

The stress test, like 20% or more of them, is “falsely positive,” meaning abnormal even though there’s nothing wrong with you. Another 30% are equivocal, not clearly abnormal but also not clearly normal. Now up to 50% of people tested “need” a heart catheterization in the hospital to clarify this frightening uncertainty. You might end up with a stent or two, even bypass surgery. Your simple $20 cholesterol panel has metamorphosed into $100,000 in hospital procedures.

That familiar sequence is followed thousands of times, seven days a week, 365 days a year.

If a disease lacks a procedure . . . create one

Congestive heart failure is among the most common diagnoses in the hospital nowadays.

Congestive heart failure is the result of injury to the heart muscle such as that occurring during heart attack, viral infections of the heart (myocarditis), poorly controlled high blood pressure, and a smattering of other rare causes. Eight million Americans with congestive heart failure account for over one million hospital admissions annually (AHA Update, 2007). It has become so common, in fact, that it has ranked as number one cause for hospital admission for the last several years.

Heart failure is a frightening condition causing the sufferer to gasp for breath. Excess fluid accumulates in the lungs, amplifying the work of breathing and imparting a feeling of unease. Some heart failure sufferers struggle to the point of blacking out or requiring mechanical ventilation on a respirator.

There are a number of standard treatments for heart failure that usually rapidly rescue the patient from the brink of respiratory failure. These generally consist of intravenous diuretics that force the kidney to clear excess water rapidly, medications to increase heart muscle strength, and other treatments. It’s not uncommon for a heart failure patient to drop 10–20 lbs. in water weight with treatment. The treatments are quite effective for the majority of patients with rapid relief of the breathlessness generally obtained within hours.

However, the problem with congestive heart failure is not generally the rapidity or effectiveness of acutely providing relief, it is the chronic recurring nature of the disease. Someone can come to the hospital, obtain prompt treatment with relief of the breathlessness within 48–72 hours, only to return to the hospital in several weeks with a recurrence of the same process.

As common as congestive heart is in hospitals, it has also presented the perennial problem: how to convert this frequent reason for hospitalization into a profit opportunity. Some people who experience heart failure will undergo the usual sequence of heart procedures of heart catheterization, stents, bypass surgery, valve surgery, etc. But, because heart failure tends to be a repeatedly recurring event, even patients tire of the “need” for heart procedures. Then how can more heart failure occurrences be converted into profitable events?

A unique principle operates in the medical device market: If a disease lacks a procedure . . . create one.

Several problems are solved by such a principle. First, procedures are much more generously reimbursed by insurers than standard medical care without procedures. Two, the physician is provided an opportunity to also bill at a higher level. Third, patients often love the more dramatic, heroic nature of procedures, whether or not there is true benefit.

To the rescue of the poorly reimbursed area of congestive heart failure walks a Minnesota company called CHF Solutions, Inc., manufacturers of the Aquadex device.

Cost? $14,500 plus $900 per filter every time a patient gets one treatment. The Aquadex works by a decades-old process called ultrafiltration, used for many years but used principally for kidney failure not severe enough to require regular dialysis. New York cardiologist Howard Levin simply adapted the process, using smaller catheters inserted into the arm veins, in 2000. As in conventional ultrafiltration, blood is taken from the body from a catheter, passed through a filter that removes excess water, then returned to the body.

This is a serious effort. Dr. Levin raised $51 million in venture backing on top of $12 million seed capital. The device sailed through the Food & Drug Administration in June 2002, since it was labeled a newer form of ultrafiltration, thereby obtaining approval through the FDA’s 501k rule, a minor modification of existing technology. (Many truly technologically unique devices do come to market and therefore require the full process of FDA approval, a generally lengthy and costly process for devices. However, there’s another way: bill a device as “substantially equivalent” to an existing technology and the approval process is relatively quick and easy.)

In an industry publication, Cath Lab Digest, Dr. Levin was interviewed in February, 2003, and proclaimed, “We can treat many of the symptoms of heart failure, but we’re a long ways off from a cure. That’s why new technologies are so exciting, such as LVADs for the very sickest heart failure patients; biventricular pacing for the small subset of patients who seem to benefit from it; and simplified ultrafiltration such as the System 100 that can be applied to a broad range of congestive heart failure patients with fluid overload. “

What does this have to do with heart scans and heart disease reversal? Nothing-directly. I highlight this phenomenon because it caricatures how things work in medicine and health care in general, more so in cardiovascular diseases in which the profit motive is especially deeply ingrained. Focus on a need, then generate a profitable treatment for it. Profits are what drive growth, marketing, sales, and expansion into new revenue-generating niches.

Sadly, the reverse principle does not work: Replace profitable procedures with unprofitable strategies, regardless of their effectiveness. Replacing coronary angioplasty and coronary stent implantation, or bypass surgery, with intensive prevention efforts is no easy matter. Just witness the enormous resistance to the concept of early heart disease detection achieved with heart scans. A day doesn’t go by without a major media outlet bashing heart scans, or confusing them with CT coronary angiograms with claims of excessive radiation.

But the mounting volume of criticisms against heart scans also means that they are gaining some traction in mainstream thinking. But will there be a day when they replace the need for profitable procedures? I believe they will, when coupled with a powerful program of prevention, but don’t hold your breath.

Blood sugar lessons from a Type I diabetic

A friend of mine is a Type I, or childhood onset, diabetic. He's had it for nearly 50 years, since age 6. He's also in the health industry and is a good observer of detail.

He made the following interesting comments to me recently when talking about the effects of various foods on blood sugar:

"When I eat normally, like some vegetables or salad and meat, I dose up to 10 units of insulin to control my blood sugar.

"If I eat a turkey sandwich on two slices of whole wheat, I usually dose 15 units. The bread makes my blood sugar go to 300 if I don't.

"If I eat a Cousins's Sub [a local submarine sandwich chain], I dose 15 units. The bread really makes my blood sugar go up.

"I can only eat a Quarter Pound from McDonald's once a year, because it make my blood sugar go nuts. I dose 15-20 units before having it, and I feel like crap for two days afterwards.

"If I eat Mexican food, I have to dose 15-20 units. For some reason, it's gotten worse over the years, and I need to dose higher and higher.

"Chinese food is the absolute worst. I dose 20-25 units before eating Chinese. I'll often have to dose more afterwards, because my blood sugar goes so berserk."


Nothing beats the real-world observations on the impact of various foods on blood sugar than the observations of people with Type I diabetes. All the insulin they get is in a syringe. Dosing needs to match intake.

Personally, though I love the taste of Americanized Chinese food, I've always been suspicious of what exactly goes into these dishes. But I was unaware of the blood sugar implications.

The impact of Mexican I believe can be attributed to the cornstarch used in the tacos and tortillas, though I also wonder if there are other starches being snuck in, as well.

Lessons about omega-3s from Japan















Image courtesy of apc33.

Japan provides a useful "laboratory" for studying the effect of a culture that relies heavily on eating fish.

The JELIS Trial, the topic of a previous Heart Scan Blog post, showed that supplementation with the single omega-3 fatty acid, EPA, 1800 mg per day (the equivalent of 10 capsules of 'standard' fish oil that contains 180 mg per day of EPA, 120 mg of DHA) significantly reduced heart attack in a Japanese population. Interestingly, this benefit was additive to the already substantial intake of omega-3 fatty acids among the general Japanese population, a population with a fraction of the heart attacks found in western populations like the U.S. (approximately 3% over 5 years in Japanese compared to several-fold higher in a comparable American group).

While there may be genetic and other cultural and lifestyle reasons behind the dramatically reduced cardiovascular risk in Japanese, it is undeniably at least partially due to the increased intake of omega-3 fatty acids from fish. Incidentally, the purported benefits of omega-3 fatty acids provide a vigorous counter-argument to the idea that all humans should be vegetarians.

Anyway, if we were to take some lessons from the Japanese and their greater habitual intake of omega-3 fatty acids from fish, they might include:

--Rural and coastal Japanese are the sub-populations with the highest reliance on fish, about a quarter-pound a day. (Gives new meaning to the idea of a "Quarter Pounder," doesn't it?) This is at least five-times greater than the intake of an average American.

--Likewise, the blood level of omega-3s in the blood of Japanese is 5-fold higher than in Americans.

--The average intake of omega-3s (EPA + DHA) among a broadly-selected population of Japanese is 850 mg per day (320 mg EPA; 520 mg DHA). Intake ranges from 300 mg per day all the way up to 3100 mg per day.

--Greater omega-3 intake (EPA + DHA) is associated with lesser carotid intimal-medial thickness, an index of body-wide atherosclerosis.

--Japanese have far less heart attack and stroke despite greater prevalence of smoking (nearly half of Japanese) and drinking.

--Total fat intake (percent of calories) is nearly identical between Americans and Japanese. It's the proportion of fat calories from omega-3 that is greater, the proportion of omega-6 that is less in Japanese.


The Japanese eat their fish in ways that we do not: As sashimi (raw, as with sushi in its various forms like Nigiri and Chirashi); fried in tempura; shaved, dried fish sprinkled on about anything you can imagine (it's not as bad as it sounds); as a snack, as in dried cuttlefish (which you can purchase in packages as a portable, sweetened fish that you eat on-the-run--I know it sounds awful, but don't poke fun at it until you've tried it); in "soups" with soba noodles. Fish is commonly consumed with rice and soy sauce, as well as other soy-based foods, such as tofu, miso (soy bean paste), or natto. 


I believe that there are some lessons to take from the Japanese and their fish-consuming habits:

1) An omega-3 fatty acid intake of at least 1000 mg per day yields measurable cardiovascular benefits. 

2) Despite the fears over mercury and pesticide residues in fish, this seems to not have played out to be a real-life effect in the Japanese, who consume five-fold greater quantities of fish. 

3) My mother was right after all when she encouraged us to eat more fish. 


DIRECT Study result: Low-carb, Mediterranean diets win weight-loss battle

Drs. Iris Shai and colleagues released results of a new Israeli study, the Dietary Intervention Randomized Controlled Trial (DIRECT) Trial, that compared three different diet strategies. Of those tested, a low-carbohydrate diet was most successful at achieving weight loss.

You can find the full-text of the study on the New England Journal of Medicine website.

322 participants followed one of three diets over two year period. Compared head-to-head, the (mean) weight loss in each group was:

• 2.9 kg (6.4 lbs) for the low-fat group
• 4.4 kg (9.7 lbs) for the Mediterranean-diet group
• 4.7 kg (10.3 lbs) for the low-carbohydrate group

(Average age 52 years at start; average body-mass index, or BMI, 31.)

The conclusion was that the low-carb diet performed the best, with 60% greater weight loss, with the Mediterranean diet a close second.


The diets

The low-fat diet was based on the American Heart Association diet, with 30% of calories from fat (10% from saturated fat) and food choices weighted towards low-fat grains, vegetables, fruits, and legumes and limited additional fats, sweets, and high-fat snacks; calorie intake of 1500 kcal per day for women and 1800 kcal per day for men was encouraged.

The Mediterranean diet was a moderate-fat diet rich in vegetables, with reduced red meat, and poultry and fish replacing beef and lamb. Total calories from fat of 35% per day or less was the goal, with most fat calories from olive oil and a handful of nuts. Like the low-fat program, calories were limited to 1500 kcal per day for women, 1800 kcal per day for men.

The low-carbohydrate diet was patterned after the popular Atkins’ program, with 8% participants achieving the ketosis that Dr. Atkins’ advocated as evidence that a fat-burning metabolism was activated, rather than sugar-burning as fuel. For the 2-month “induction phase,” 20 grams of carbohydrates per day was set as the goal, followed by 120 grams per day once the weight goal was achieved. Unlike the other two diets, calories, protein and fat were unlimited.


Weight loss, lipids, inflammation

You can see from the weight loss graph that the low-carb approach exerted the most dramatic initial weight loss. Interestingly, much of the weight-loss benefit was lost as the carbohydrate intake increased, by study design, back to 120 mg per day. However, the other two diet approaches showed similar phenomena of “giving back” some of the initial weight loss.

The low-carbohydrate diet exerted the greatest change in cholesterol, or lipid, panels: increased HDL 8.4 mg/dl vs. 6.3 mg/dl on low-fat; the triglyceride response was the most dramatic, with a reduction of 23.7 mg/dl vs. 3.7 mg/dl on low-fat. Interestingly, the LDL cholesterol-reducing effect of all three diets was modest, with the most reduction achieved by the Mediteranean diet.

The inflammatory measure, C-reactive protein (CRP), was reduced most effectively by the low-carb and Mediterranean diets, least by the low-fat diet. HbA1c, a measure of long-term blood sugar, dropped significantly more on the low-carb diet.

When the final dietary composition was examined, interestingly, there really were only modest differences among the three diets, with 8% less calories from carbs, 8% greater calories from fat, comparing low-carb to low-fat, with Mediterranean intermediate.



Taken at face value, this useful exercise quite clearly shows that, from the perspective of weight loss and correction of metabolic parameters like triglycerides, HDL,CRP, and blood sugar, low-carbohydrate wins hands down, with Mediterranean diet a close second.

It also suggests that a return to a carbohydrate intake of 120 mg/day allows a partial return of initial weight lost, as well as deterioration of metabolic parameters after the initial positive changes.

Although the study has already received some criticism for such potential flaws as the modest number of Atkins’ followers achieving ketosis (8%), suggesting lax adherence, and the reintroduction of the 120 mg/day carbohydrate advice, I can suspect that these may have been compromises drawn to satisfy some Institutional Review Board. (Whenever a study is going to be conducted involving human subjects, a study needs to pass through the review of an Institutional Review Board, or IRB. IRB’s, while charged to protect human subjects from experimental abuses, also tend to be painfully conservative and will block a study or demand changes even if they are not dangerous, but just veer too far off the mainstream.)


However, several unanswered questions remain:

1) How would the diets have compared if the carbohydrate restriction were continued for a longer period, or even indefinitely? (The divergences would likely have been dramatic.)
2) Will low-carb exert the same cardiovascular event reduction that the Mediterranean approach has shown in the Lyon study and others?
3) Are there effects on health outside of the measures followed that differ among the three diets, such as cancer? (I doubt it, especially given the modest real differences over time. But this will be the objection raised by various "official" organizations.)


I would further propose that:

Low-fat diets are dead

The AHA will cling to their version of low-fat diet, based on difficulty in changing course for any large, consensus-driven organization, not to mention the substantial ($100’s of millions) revenues derived from endorsing low-fat manufactured products. The AHA will also point to the lack of difference in LDL cholesterol among the three, since they cannot get beyond the fact that there’s more to coronary risk—a lot more—than LDL.


Off-the-shelf diets achieve off-the-shelf results

If you just need a T-shirt, a medium might fit fine. But if you’d like a nicely fitting suit or dress, then tailoring to your individual proportions is needed. When aiming towards maximizing benefits on lipoproteins and coronary risk, none of these diets achieve the kinds of changes we often need for coronary plaque reversal, as in the Track Your Plaque program. That requires making dietary changes that exert maximal effects on lipoprotein patterns.

Do I sell heart scans?

I came across a criticism of the Track Your Plaque program recently that suggested that it was nothing more than a program to sell CT heart scans.

Huh?

I suppose if you say that the Track Your Plaque program is nothing more than a way to sell heart disease prevention, omega-3 fatty acids from fish oil, vitamin D, better nutrition, and better identification of causes of heart disease . . . well, I believe that would be true.

But is the program a "front" to sell heart scans?

No, it is not, nor has it ever been.

I've heard about these peculiar suspicions about the program before. Though I've never taken them seriously, let me clear up any lingering uncertainty:


--I have no relationship with any heart scan center, scanning facility, or hospital other than to interpret heart scans.

I do not own a scanner, I have no financial interest in a scanner or scanning center, nor have I ever had any interest. I also have no plans to do so in the future. Let business people in the imaging business do that. I want no part of it. I have seen what these people go through and, frankly, I want no part of it, nor do I want the appearance that I am advocating scans to make money. I'm accused of trying to make money from scans even when I do not have any financial interest!


--I do not sell heart scans or imaging packages, nor have I ever done so.

You can't buy a scan through Track Your Plaque, The Heart Scan Blog, or through me. To me, heart scans are simply a measuring tool to identify the extent of coronary plaque, as well as a tracking tool to follow its course. Without it, there would be no Track Your Plaque. But there is also no alternative. The closest alternative would be carotid intimal-medial thickness, a technique, while useful, is a distant second choice to indirectly gauge coronary plaque by examining the thickness of the carotid lining (not carotid plaque). Perhaps in 10 years, a better measure to gauge and track coronary plaque will emerge that has superior aspects over CT heart scanning. If reasonable, safe, accessible, and quantitative, then Track Your Plaque may adopt that technology as its measuring tool.

Track Your Plaque is not about heart scanning; Track Your Plaque is about measuring and tracking plaque that, in 2008, is still best accomplished with CT heart scans.


--I make loads of money from heart scans and Track Your Plaque.

Yeah, right.

Track Your Plaque is a volunteer venture for my team; none of us get paid a penny for doing all we do, including me. We charge a membership fee on the website (somewhere around $6-7 a month) to pay our expenses, such as code writing for our proprietary software (much of it remains under development), printing costs, modest legal costs, the costs of doing business (e.g., accountant). Despite the fact that Track Your Plaque and the Heart Scan Blog occupies a substantial part of the day of the Track Your Plaque team, none of us are reimbursed for our time. I do believe, however, that this concept is so enormously powerful that it will, someday, pay us all enough to allow us to devote more time and effort to it.

Personally, I can't wait to devote more time and effort to this concept that is simple, logical, and effective. More research is needed, more development is needed, more discussion is needed. Right now, it is all accomplished outside of our busy schedules, including my full-time cardiology practice. I continue to have 7 am procedures, middle-of-the-night calls, weekend hospital rounds and emergencies (though virtually none of these are the patients involved in prevention, but the "other" people: atrial fibrillation, elderly heart failure patients, rhythm disorders, cardiomyopathies, pulmonary hypertension, peripheral vascular disease, the non-compliant).


--The book, Track Your Plaque, is a gimmick to sell you a heart scan.

No, it's a program that relies on this technology. But there's no special deal, no discounts, no steering to heart scan centers that I have a special arrangement with. No such thing exists, nor has there ever been such an arrangement.


I've heard it all. Early on, when I was helping my friend, Steve Burlingame and his wife, Nancy, set up Milwaukee Heart Scan, I helped by providing medical oversite, education of physicians and public, and interpreting heart scans. After all, in the "early days," nobody knew anything about heart scans. It was a long, hard climb against ignorance, habit, entrenched thinking, stubbornness, and stupidity. I've been paid next to nothing for all this. I told Steve long ago that, given the extraordinary expenses of maintaining an independent scanning center, that he should first pay his expenses, pay his technologists, receptionists, and nurse, pay himself, then pay me for reading scans if he had any money left over. Most of the time, Steve had nothing left over and I was paid nothing.

So, while some of my colleagues were assuming that I was rolling in money from "promoting" heart scans, the reality was that I was doing nearly everything for free. (It certainly wasn't the high life I was living; I don't drive a Mercedes, take fancy vacations, none of that. In fact, I work about 51 weeks a year.)

Why do I do this if it doesn't yield a big flow of money? Because I believe in it as a superior path to the conventional. If I were simply interested in making more money--I wouldn't do it. I would simply do what all my cardiology colleagues are doing: more heart catheterizations, more angioplasties and stents, learning how to do carotid stents, iliac stents, peripheral angioplasty, renal stents, acquiring the skills to put in defibrillators, new device insertion like umbrellas in the interatrial septum, etc. There's plenty more money in that. It's also not that hard. I know, because that is my background: high-risk cardiac interventions. That's what I was trained to do, that's what I did from a number years, until I started to see that this was nothing more than "putting out fires" in people who became increasingly ill and reliant on bail-out procedures. It makes lots of money, but it is also fundamentally wrong.

So, no, I do not sell heart scans, nor is the Track Your Plaque program or The Heart Scan Blog meant to promote heart scans except as a tool for tracking this disease.

That's it, pure and simple.

Plaque is the new cholesterol

Which is more important: cholesterol or coronary plaque?

Ask what Dr. Michael Eades' calls "statinators," and you will likely receive a befuddled look. Or, you might receive comments like "Measuring plaque has never been shown to reduce mortality."

While risk factors for heart disease are important, no doubt (my office practice is about half lipid consultation and complex hyperlipidemia management), for many they have become an end in themselves. In other words, LDL cholesterol in particular dominates thinking so much that it has caused many to exclude the fact that plaque---coronary atherosclerotic plaque---is the disease itself.

Dozens of studies, from the St. Francis Heart Study to the 25,000-participant UCLA registry, to the recently-released MESA database (ethic differences, women, as well as superiority to carotid measures) have repeatedly shown that heart scan scores (coronary artery calcium scores) are superior to conventional risk factors (usually via the Framingham risk score) for predicting future heart attack and other events. And the differences are not minor incremental differences. The predictive power of plaque measurement via heart scanning is multiples better: 4 times, 10 times, 20 times or more in various subgroups.

Much of what we do in medicine is not based on long-term studies of outcome, pitting some diagnostic measure or treatment against placebo. It is already standard practice to measure plaque via heart catheterization, crudely via stress testing, and increasingly popular CT coronary angiography. None of these methods have been subjected to studies comparing testing vs. not testing in a large population, followed by some program of prevention to assess differences in mortality, heart attack, and other events.

Why should heart scan be held to such a standard?

Dr. Scott Grundy, lipid guru and one of the experts who sat on the Adult Treatment Panel-II for lipid management guidelines, recently stated [emphasis added]:

"Imaging has at least 3 virtues. It individualizes risk assessment beyond use of age, which is a less reliable surrogate for atherosclerosis burden; it provides an integrated assessment of the lifetime exposure to risk factors; and it identifies individuals who are susceptible to developing atherosclerosis beyond established risk factors. Also of importance, in the absence of detectable atherosclerosis, short-term risk appears to be very low."

Well said, and from a vocal statinator, to boot.

Sadly, Dr. Grundy goes on to say how plaque imaging can serve to better determine who will benefit from statin drug use.

Of course, you and I know that there is far more to reduction of cardiovascular risk applied to a framework of serial plaque quantification ("tracking plaque"!) than statin drugs. I doubt that a man as intelligent as Dr. Grundy truly believes this. I suspect that he is simply stating what he knows what will be published without resistance in the standard medical literature, trying to achieve a modest incremental success just by raising consciousness about heart scanning and plaque imaging: first things first.

Maybe next will be a plaque-tracking, or even a plaque-reducing, mainstream conversation, just like the one we've been conducting for the past four years.

Track Your Plaque success story blows it

Joe was a Track Your Plaque Success Story. With a starting heart scan score of 278, he dropped it 12 months later to 264, a 5% reduction. Though not a huge reduction, Joe's risk for a heart attack or other coronary event was virtually zero. I was very proud of Joe.

Among the culprit lipoprotein patterns that caused Joe's plaque was lipoprotein(a), or Lp(a). Niacin was therefore crucial to his program. It was among the principal reasons he dropped his heart scan score and reduced his risk for heart attack so dramatically.

Since he retired, Joe has been freewheeling around the country, traveling and having a great time. He consequently stopped thinking about his heart disease and Lp(a). He also tired of the occasional hot flushes he'd experienced with niacin. Though the flushes were promptly aborted by drinking two glasses of water, he simply didn't want to be bothered.

So when Joe saw this interesting and tantalizing "flush-free niacin" on the store shelf, he grabbed it.

Joe came back to the office. His blood pressure was 190/94, so high that he was having occasional chest pains from it (which can happen when something called "left ventricular diastolic dysfunction" develops from hypertension). His lipoprotein patterns were terrible, including a big upward jump in Lp(a) and drop in HDL. So I asked him to have another heart scan right away: Score 371, a 40% increase. In other words, his program went down the toilet.

Why?

Simple: Flush-free niacin. I've said it before (No flush = No effect and No flush niacin kills) and I'll say it again:

Flush-free or No-flush niacin is a complete, unadulterated, completely ineffective SCAM.

Flush-free or no-flush niacin is not a substitute for niacin. Joe is yet another example of how dangerous this scam can be. It turned one of our great success stories into a failure.

Please, please, please do not fall for this misleading and potentially dangerous scam product. While the product itself is not intrinsically dangerous, it denies you the benefits of the real thing: niacin.

Thankfully, the mistake in Joe's program was caught before a heart attack or other catastrophe. He did manage to pass a stress test, though with a flagrantly out-of-control blood pressure response. We'll get him back on track--but with niacin, the real thing.

Dr. Cannell comments on vitamin D lab tests

As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D.

Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here.

(I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.)


Does it matter what reference lab my doctor uses?

Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."

Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.

Demand for vitamin D tests soars as nutrient's potential benefits touted.

Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.



My doctor prescribed Drisdol, 50,000 IU per week. What is it?

Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.



What is the ideal level of 25(OH)D?

We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

I have advanced renal failure and I'm on dialysis, how much vitamin D should I take?

The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases.

When I asked my doctor for a 25(OH)D blood test, he just laughed and said it was all idiotic. What can I do?

Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.

Privileged information

In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit.

Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights.

But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.

Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly.

Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.

And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies.

Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few.

Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled.

Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets.

I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people.

Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.

But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on.

Dr. Jeffrey Dach on the Track Your Plaque program

Dr. Jeffrey Dach posted a great piece on his blog, Bioidentical Hormone Blog , about his perspective on the Track Your Plaque program.

It's worth reading even for those familiar with the program, just to see a slightly different perspective. He also included many great graphics to illustrate his points.

Vitamin D and programmed aging?

As we age, we lose the capacity to activate vitamin D in the skin.

Studies suggest that, between ages 20 and 70, there is a 75% reduction in the ability to activate vitamin D. The capacity of conversion from 25 (OH) vitamin D to 1,25 di(OH) vitamin D also diminishes.

From Holick, M. 2006

This would explain why 70-year olds come to the office, just back from the Caribbean sporting dark brown tans, are still deficient, often severely, in blood levels of vitamin D (25(OH) vitamin D). A tan does not equal vitamin D.

A practical way of looking at it is that anyone 40 years old or older has lost the majority of ability for vitamin D activation.

This often makes me wonder if the loss of vitamin D activating potential is nature's way to get rid of us. After all, after 40, we've pretty much had our opportunity to recreate and make our contribution to the species (at least in a primitive world in which humans evolved): we've exhausted our reproductive usefulness to the species.

Is the programmed decline of vitamin D skin activation a way to ensure that we develop diseases of senescence (aging)? The list of potential consequences of vitamin D deficiency includes: osteoporosis, poor balance and coordination, falls and fractures; cancer of the breast, bladder, colon, prostate, and blood; reductions in HDL, increases in triglycerides; increased inflammation (C-reactive protein, CRP); declining memory and mentation; coronary heart disease.

Isn't that also pretty much a list that describes aging?

A fascinating argument in support of this idea came from study from St Thomas’ Hospital and the London School of Medicine:

Higher serum vitamin D concentrations are associated with longer leukocyte telomere length in women

Telomeres are the "tails" of DNA that were formerly thought to be mistakes, just coding for nonsense. But more recent thinking has proposed that telomeres may provide a counting mechanism that shortens with aging and accelerates with stress and illness. This study suggests that both vitamin D and inflammation (CRP) impact telomere length: the lower the vitamin D, the shorter the telomere length, particularly when inflammation is greater.
















Data supporting vitamin D's effects on preventing or treating cancer, osteoporosis, lipid abnormalities, inflammation, cardiovascular disease, etc., is developing rapidly.

Now the big question: If declining vitamin D is nature's way of ensuring our decline and death, does maintaining higher vitamin D also maintain youthfulness?

I don't have an answer, but it's a really intriguing idea.

Synthroid, Armour Thyroid, and the battle for T3

In the last Heart Scan Blog post on thyroid issues, Is normal TSH too high?, the provocative findings of the the HUNT Study were discussed. The text of the study can be found at:

The association between TSH within the reference range and serum lipid concentrations in a population-based study. The HUNT Study

Hypothyroidism, or low thyroid that is signaled by high thyroid-stimulating hormone, TSH, is proving far more prevalent an issue than previously thought. While previous estimates put hypothyroidism as affecting only about 3% of younger populations, 10-20% of older populations (women more so), data like the HUNT Study suggest that, if lower and lower TSH levels (higher thyroid) are necessary for perfect heart health, then many more people stand to benefit than we used to think.

But another crucial issue in the world of hypothyroidism: Is T4 (thyroxine) enough? Or should we be supplementing T3 (triiodothyronine) along with T4?

Your friendly neighborhood primary care doctor or endocrinologist would likely argue vehemently that T4 (as Synthroid, Levoxyl, levothyroxine, and others) is adequate and not subject to the impurities and contaminants of natural thyroid extracts. They would also argue that T4 is effectively converted to T3 at the tissue level, and exogenous supplementation is unnecessary.

Others--most of all thyroid patients themselves, along with thyroid advocates like Mary Shomon and Janie Bowthorpe, along with some physicians--argue that supplementing T3 along with T4 can be very important. They argue that people feel better, have more physical energy, lose weight more effectively, and more completely resolve many of the phenomena of hypothryoidism with T3 added. There are also some data that argue the same.

Adding T3 to the mix may address the presumed poor conversion of T4 to T3 that is peculiar to some people. It may overcome the "reverse T3" phenomenon, the production of a useless look-alike T3 that occurs in some people. It may also (anecdotally) exert greater effects on some lipid/lipoprotein parameters, such as Lp(a).

My experiences adding T3 to T4 have been mixed: Some feel better, others do not. Some show objective improvements, others do not.

Nonetheless, hypothyroidism, or incompletely corrected hypothryoidism by way of inadequate T3, is an issue to consider in your plaque-control program.

More on this somewhat complex issue, along with practical solutions to consider, can be found on the Special Report to be released this week on the Track Your Plaque website.

Letter to New York Times

All right. I sent a Letter to the Editor to the New York Times. No word from them; it's no longer news.

So here is what I tried to convey.

While the authors overall did a credible job of talking to my colleagues and laying out the issues, they made the crucial and boneheaded mistake of confusing CT heart scans with CT coronary angiograms. Sadly, many people who may have been considering having a simple screening heart scan may be scared away by the confused authors, Alexn Berenson and Reed Abelson.

They do correctly point out that, while CT coronary angiograms are fascinating examples of technology and a way of visualizing coronary arteries, this test all too often is being subverted into the "let's make money from high-tech testing" medical model. It's also a test that frequently leads to the "real" test, heart catheterization, since the "time bomb" you have in your arteries might "need" a stent.

CT coronary angiograms are also virtually useless for purposes of tracking disease, since they are not longitudinally (along the length of the artery) quantitative, nor should anyone be exposed to this much radiation repeatedly.

A simple heart scan, on the hand, provides a longitudinal summation of coronary plaque volume. Radiation exposure is sufficiently low that repeated scanning can be performed for purposes of tracking . . .yes, track your plaque.

Poorly-informed reporters can do a lot of damage. As always, you and I must dig a little deeper for the truth.




Dear Editor,

Re: Weighing the Costs of a CT Scan’s Look Inside the Heart

The Times featured an article on June 29th that discussed rapidly expanding use of CT scans for the heart:
Weighing the Costs of a CT Scan’s Look Inside the Heart.

The authors, Alex Berenson and Reed Abelson, stated that CT heart scans “expose patients to large doses of radiation, equivalent to at least several hundred X-rays, creating a small but real cancer risk.”

I’d like to offer a clarification.

Though the authors discuss both CT heart scans and CT coronary angiograms, they confuse the two and use the terms interchangeably.

A heart scan is a simple screening test for coronary atherosclerotic plaque. It detects the presence of calcium in the heart’s arteries, provided as a “score.” (Because calcium occupies 20% of total plaque volume, knowing the amount of calcium tells you how much total coronary plaque is present by applying this simple proportion.) Just having a high score should not prompt heart procedures, since people undergoing simple screening heart scans are without symptoms. However, a stress test may yield some useful information.

On present-day CT devices, heart scans expose a patient to 0.4 mSv of radiation on an electron-beam, or EBT, device, and on up to 1.2 mSv on a 64-slice multi-detector, or MDCT, device, compared to 0.1 mSv during a standard chest x-ray. CT heart scans are therefore performed with about the same quantity of radiation as a mammogram done to screen women for breast cancer, or about the equivalent of four chest x-rays on an EBT scanner, up to 12 chest-xrays on a MDCT scanner.

CT coronary angiograms, while performed on the same devices as heart scans, require x-ray dye to fill the contours of the coronary arteries. It also requires up to several hundred times more radiation. While new engineering innovations are being introduced that promise to reduce this exposure, the current devices being used today do indeed require a radiation dose equivalent to 100 to 400 chest x-rays (usually in the range of 10-15 mSv), a value that equals or exceeds that obtained during a conventional heart catheterization.

While heart scans are most useful to detect and quantify plaque that can help determine the intensity of a heart disease prevention program, CT coronary angiograms are generally used as prelude to hospital procedures like catheterizations, stents and bypass surgery. That’s because they are performed to look for (or rule out) “severe” blockages.
CT heart scans and CT coronary angiography are therefore two different tests that yield two different kinds of information, and yield two entirely different levels of radiation exposure.

This confusion from a major and respected media outlet like the New York Times is unfortunate, because it could persuade millions of people who otherwise could benefit from simple heart scans to avoid them because of misleading information on radiation exposure of a different test.

Thank you.

Red yeast rice alert

While there have been some positive reports in the media lately about the cholesterol-reducing effects of red yeast rice, Consumer Lab has issued a very concerning report.

Because Consumer Lab is a subscription website (incidentally, the $20 per year membership fee is money well spent for insightful tests on many supplements, though new reports only come out a handful of times per year), I won't discuss the results of their red yeast rice in its entirety.

However, Consumer Lab testing uncovered several disturbing findings:

--The lovastatin content varied by a factor of 100, from 0.1 mg per tablet/capsule in one brand up to 10.6 mg in another brand. By FDA regulations, lovastatin is a drug and NO red yeast rice preparation is supposed to contain ANY lovastatin. Nonetheless, despite the marketing of supplement manufacturers, it is probably the lovastatin that is largely responsible for the LDL-reducing effect. The monacolins or mevinolins in red yeast rice add little, if any, further LDL-reducing effect.

--Several preparations contain a potential kidney toxin called citrinin. The Walgreen's product, specifically, contained substantial quantities of this toxin.



Interestingly, the FDA has taken repeated action against red yeast rice manufacturers and distributors because they continue to contain lovastatin. In the FDA's most recent action in August, 2007, for instance, Swanson's product and Sunburst Biorganics' Cholestrix, were both sent letters to stop selling their product because it contained lovastatin.

The Consumer Lab findings would explain the enormous variation in LDL-reducing effect of various red yeast rice products. In my experience, some work and reduce LDL 40 mg/dl or so, some fail to reduce LDL at all, others generate a modest effect, e.g., 5-10 mg/dl LDL reduction.

In effect, red yeast rice IS a statin drug, albeit a highly variable and weak one. Although readers of The Heart Scan Blog know that I am a big fan of nutritional supplements and self-empowerment in health, I am a bigger fan of truth. I despise B--- S---- of the sort that emits from some nutritional supplement manufacturers and drug companies.

I am puzzled by much of the public's readiness to embrace a statin drug if it comes from a supplement company while avoiding it if it comes from a drug manufacturer. Personally, I do not like the drug industry, their questionable (at best) ethics, their aggressive marketing tactics, their sleazy sales people.

But, in this instance, if a statin effect is desired, I'd reach for generic lovastatin before I purchased red yeast rice. The Consumer Lab report tells us that red yeast rice IS essentially a statin drug, an inconsistent one that often contains a potential toxin.

"Average amount of heart disease for age"

A 72-year old woman came to my office after a complicated hospital stay (unrelated to heart disease). She'd undergone a CT coronary angiogram and heart scan as part of a pre-operative evaluation prior to a surgery for a non-heart related condition.

The heart scan portion of the test (I was impressed they even did this) yielded a heart scan score of 212. The CT coronary angiogram portion of the test revealed a 50% blockage in one artery, a lesser blockage in one other artery.

The cardiologist consulting on the case advised her that the amount of coronary disease detected was insufficient to pose risk during her surgical procedure. He also advised her that she had "an average amount of disease for age." He thought that nothing further was necessary since she was "average."

Say what?  

What if I told you that you have an average amount of cancer for your age? After all, cancers become more common the older we get. Who would find that acceptable?

Then why should ANY amount of coronary atherosclerotic plaque be "acceptable for age"? Coronary plaque is a degenerative disease that poses risk for rupture. While it is indeed common, by no means should it be acceptable.

I would bet that this same cardiologist would be from the same school of thought that would be eager to advise heart catheterization, stent, and other procedures--revenue-generating procedures--should she have a heart attack appropriate for age.

I wish that I could tell you that this silly comment was provided by some peculiar, "everyone-knows-he's-crazy" doctor. But it was not. It was a solidly mainstream physician. He pooh-poohs nutrition, laughs when asked about nutritional supplements, thinks anyone complaining about symptoms less than a full-blown heart attack is a baby. He is respected by the primary care physicians, lectures on the advantages of prescription medications. In short, he is your typical conventional cardiologist.

This is the way they think. I know, because I was one of them. Thankfully, something banged me upside my head one day (my Mother's sudden cardiac death) and tipped me off to the painful irony of the conventional approach to heart disease.

There is NO amount of coronary disease appropriate for age. This notion is a remnant of the paternalistic, "I-know-better-than-you" attitude of the last century of medicine.

The 21st century promises a new age.

Quantum leaps

A reader of The Heart Scan Blog and member of the Track Your Plaque program posted this comment on The Heart.org:

*The facts speak for themselves.*

Dr. William Davis and Dr. William Blanchet, your patients thank you for the low cost PREVENTIVE care you prescribe. The published facts speak for themselves. It is indeed a sad state of affairs, that the larger cardiology community does not take the time to research the data and results you have been reporting. Unfortunately it is the patients who are the victims of the mainstream, inappropriate, treatment protocols, as evidenced with the ongoing high rate of CV death rate.

I am dumbfounded by the lack of open-minded inquisitive curiosity to thoroughly research your claims by many/most cardiologists. Understood, we are all busy, but that is no excuse to stick with practices that do not result in major breakthrough improvements in patient outcomes.

Then again, we are all humans, and when "we" are convinced that "our" approach is correct, "we" tend to conveniently ignore any evidence to the contrary. "We" like to believe "we" have been right all along.

A very insightful book, recently published, says it all in its title: "Mistakes were made (but not by me)."

From the intensity of the comments on this topic, it is clear that we are in the middle of a battlefield. It is to be hoped that the facts will become visible before too much smoke obscures the field, and before the patients are all dead.

George Orwell said it correctly, back in 1946:

“We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, imprudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality usually on a battlefield.”

And, after several posts that preventive care with EBT would be too costly.....

*Heroic*

Prevention is what matters, but it is not very heroic. A hospital that advertises the highest volumes in heart bypasses and other heart "repair" procedures, sounds to many like a go-to place when one gets into trouble with one's heart.

Cardiologists who perform impressive surgical procedures are heroes. Not unlike fire-fighters. We celebrate them (deservedly!) for rescues and life saving heroic actions.

We tend to not pay much attention to the folks that work hard to minimize risk of calamities in the first place.

Similarly, we recently learned that it is too costly to build schools that are earthquake resistant in China. Parents had to look at their children's bodies, crushed.

Is it too graphic to imagine 20,000 American bodies, who died of heart disease, piled up on a field?

What will it take before we make prevention our first priority?

The reader also tells me that, prompted by his father's death from heart attack while following conventional advice after heart catheterization, he has lost 50 lbs and corrected his lipid patterns on the Track Your Plaque program. The reader is currently struggling with full correction of his severe small LDL pattern and is following some of the advice we discussed on our webinar recently.

Another Heart Scan Blog reader, Stan the Heretic, posted this quote from scientist, Max Planck, in his comment:


"A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it." - M. Planck

(Max Planck was a German physicist who developed quantum theory, a disruptive set of ideas that supplanted other explanations of energy mechanics of the day.)


I fear that may prove to be the case for heart disease. The revenue-generating formula for heart disease management that dominates practice in cardiovascular medicine today is so deeply ingrained into the thinking and revenue expectations of practicing cardiologists that a preventive or reversal approach just won't cut it--even if it is vastly superior.

That's why it is important for you to take control yourself. You will be the one who obtains and applies the information that saves your life or the lives of those around you. It is, in all likelihood, NOT your doctor who will save your life, but YOU.

Body count

Imagine the following headline:

War in Iraq a growing success: 20,000 Americans now dead!


If a newspaper ran that headline, we would all be outraged, and rightly so. Deaths in war are a tragedy. They are not something we celebrate.

Then why do we hear hospitals boasting about the number of bypass operations performed every year, number of heart catheterizations performed, number of heart attacks treated?


"_______ Hospital breaks 1000-heart bypass per year milestone"

"We treat more heart attacks than other other hospital in the state!"

"More people come to ________ Hospital than any other in the region!"




I hear this stuff on the radio, on TV, see it in newspapers and magazines, even on highway billboards every single day in Milwaukee.

Heart procedures, like deaths in war, are casualties of health.

They are not successes (though, of course, you can have a "successful" bypass). I see most procedures as a failure of prevention.

Death from heart attack is a failure of prevention. Tim Russert's death was a (unnecessary) failure of prevention. But so are bypass surgery, stents, and the like.

Such is the perverse state of affairs in hospitals and health: They celebrate illness. They glamorize it with ads displaying high-tech equipment, efficient staff in scrubs, "caring and friendly staff." But it is illness they are celebrating. Why? Because it has become a business necessity, a necessary strategy to remain competitive and profitable in the business called "healthcare" that makes money from treating people. The biggest return is from major procedures like bypass operations.

Every success in prevention denies the hospital an $80,000+ opportunity. You'll never hear that advertised.

No flush = No effect



"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan


Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

The Track Your Plaque “Rule of 60”

The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.


HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.


Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.


Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil


The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.

The most important weight loss tool


Question: What is the most effective tool available to help you lose weight? 


A pedometer (walk 10,000 steps, etc.)?

A treadmill? 




A bicycle?






No. None of the above. 

The most important tool you can use to achieve weight loss is your glucose monitor:



Timing of blood sugars

Because different foods generate different blood sugar (glucose) responses, the timing of your blood sugar is an important factor to consider.

This question has come up a number of times. Commenters have asked whether the one-hour postprandial glucose is timed with the start of the meal or the conclusion of the meal.

In my view, if we simply ignored all aspects of meal composition, then blood glucose should be obtained one hour after the conclusion of a meal. This is because most mixed meals (i.e., mixed in composition among proteins, fats, and carbohydrates) yield peak blood glucose levels at 60-90 minutes after consumption. Timing blood glucose to 60 minutes after the conclusion of a meal puts the sample right about at the peak.

But this is an oversimplification. For instance, here is the blood glucose behavior after so-called "complex" carbohydrates wheat bread, rye bread, rye made with beta glucan, and whole wheat pasta (50 grams carbohydrates each) in slender, healthy volunteers, mean age 29 years:


From Juntunen et al 2002

Note that blood glucose peaks at 35 minutes postprandial. (To convert glucose in mmol/L to mg/dl, multiple by 18. Thus, whole wheat bread increased blood glucose from 94 mg/dl to 122 mg/dl. Also note the lower peak glucose for pasta, but sustained higher glucose levels hours later.)

In another study, older (mean age 64 years), overweight (BMI 27.9) females with diabetes were given 50 grams carbohydrate, 50 grams carbohydrate with olive oil, or 50 grams carbohydrate with butter:


From Thomsen et al 2003. Control meal of soup plus 50 g carbohydrates ({blacktriangledown}), the control meal plus 80 g olive oil ({circ}), and the control meal plus 100 g butter (•).

In this experience, note that postprandial glucose peaks 60-120 minutes after the meals (consumed within 10 minutes), delayed more when either oil is included. Blood glucose started at 144 mg/dl and peaked as high as 230 mg/dl with carbohydrates only; peaks were reduced (along with AUC) when oil was included. (Note the differential effect, olive oil vs. butter.)

These two sets of observations give you a range of blood glucose behavior. One side lesson: Carbohydrates should never consumed by themselves, else you will pay with a high blood sugar (not to mention the hypoglycemic response later for many).

Psssst . . . There's sugar in there

You non-diabetics who check your postprandial blood sugars already know: There are hidden sources of sugar in so many foods.

By now, everybody should know that foods like breakfast cereals, breads, bagels, pretzels, and crackers cause blood sugar to skyrocket after you eat them. But sometimes you eat something you thought was safe only to find you're showing blood sugars of 120, 130, 150+ mg/dl.

Where can you find such "stealth" sources of sugars that can screw up your postprandial blood sugars, small LDL, inflammation, blood pressure, and cause you to grow visceral fat? Here's a few:

Balsamic vinaigrette
Many commercially-prepared balsamic vinaigrettes, especially the "light" varieties, have 3 or more grams carbohydrates per tablespoon. Generous use of a sugar-added vinaigrette can therefore provide 12+ grams carbs. (Some, like Emeril's and Wish Bone, also contain high-fructose corn syrup.)

Hamburgers
I learned this lesson the hard way by taking my blood sugar after having a hamburger, turkey burger, or vegetarian burger (without bun): blood sugar would go way up. The effect is due to bread crumbs added to the meat or soy.

Tomato soup
If it were just tomatoes, it would still be somewhat high in sugars. But commercially-prepared tomato soup often contains added high-fructose corn syrup, sucrose, and wheat flour, bringing sugar totals to 12 to 20+ grams per half-cup. A typical 2-cup bowl of tomato soup can have upwards of 80 grams of sugar.

Granola
Sure, granola contains a lot of fiber. But most granolas come packed with sugars in various forms. One cup of Kellogg's Low-fat Granola with Raisins contains an incredible 72 grams (net) carbohydrates, of which 25 grams are sugar.


Given modern appetites and serving sizes, you can see that it is very easy to get carried away and, before you know it, get exposed to extraordinary amounts of sugar and carbohydrates eating foods you thought were healthy.

And don't be fooled by claims of "natural" sugar. Sugar is sugar--Just check your blood sugar and you'll see. So raw cane sugar, beet sugar, and brown sugar have the same impact as white table sugar. Honey, maple syrup, and agave? They're worse (due to fructose).

How low should blood sugar be?

What should your blood sugar (glucose) be after eating?

Take a look at the data from the Whitehall study reported in 2006. The Whitehall Study stands apart from other studies in that it was very large (over 18,000 participants) who were observed for an unusually long time (33 years). All participants were administered a 50 gram glucose "challenge" at the start with glucose levels checked after the glucose challenge.

Here's what they found:




From Brunner et al 2006.

You just THINK you're low-carb

Systematically checking postprandial (after-eating) blood sugars is providing some great insights into crafting a better diet for many people.

I last discussed the concept of postprandial glucose checks in To get low-carb right, you need to check blood sugars.

Here are some important lessons that many people--NON-diabetic people, most with normal blood glucoses or just mildly increased--are learning:

Oatmeal yields high blood sugars. Even if your fasting blood sugar is 90 mg/dl, a bowl of oatmeal with skim milk, walnuts, and some berries will yield blood sugars of 150-200 mg/dl in many people.

Cheerios yields shocking blood sugars. 200+ mg/dl is not uncommon in non-diabetics. (Diabetics have 250-350 mg/dl.)

Fruits like apples and bananas increase blood sugar to 130 mg/dl or higher.

Odd symptoms, such as mental "fog," fatigue, and a fullness in the head, are often attributable to high blood sugars.

A subset of people with lipoprotein(a) can have wildly increased blood sugars despite their slender build and high aerobic exercise habits.


Once you identify the high blood sugar problem, you can do something about it. The best place to start is to reduce or eliminate the sugar-provoking food.

The LDL-Fructose Disconnect

I believe that we can all agree that the commonly obtained Friedewald LDL cholesterol (what I call "fictitious" LDL cholesterol) is wildly inaccurate. 100%--yes, 100% inaccuracy--is not at all uncommon.

This flagrant inaccuracy, unacceptable in virtually every other discipline (imagine your airplane flight to New York lands in Pittsburgh--close enough, isn't it?), is highlighted in the University of California study by Stanhope et al I discussed previously.

32 participants consumed either a diet enriched with either fructose or glucose. Compared to the effect of glucose, after 10 weeks fructose:

Increased LDL cholesterol (calculated) by 7.6%

Increased Apoprotein B (a measure of the number of LDL particles) by 24%

Increased small dense LDL by 41%

Increased oxidized LDL by 12.6%



In other words, conventional calculated LDL substantially underestimates the undesirable effects of fructose. The divergence between calculated LDL and small LDL is especially dramatic. (By the way, this same divergence applies to the studies suggesting that calculated LDL cholesterol is reduced by low fat diets--While calculated LDL may indeed be reduced, small LDL goes way up, a striking divergence.)

This is yet another reason to not rely on this "fictitious" LDL cholesterol value that, inaccuracies notwithstanding, serves as the foundation for a $27 billion per year industry.

"I dream about bread"

Marion sat in my office, sobbing.

It had been 4 weeks since the last piece of bread, bagel, or bun had passed her lips.

"I can't do it! I just can't do it! I've tried to eliminate wheat, but it's making me crazy. I'm having dreams about bread!"

Yes, Timmy, such dark corners of human behavior are truly unveiled by removing wheat from the diet. (See the previous Heart Scan Blog post, Wheat withdrawal.)

This is a real phenomenon: Wheat is the crack cocaine of the masses. Maybe you don't exchange $100 bills in dark corners of an inner city crack house, but I'll bet you paid $3.99 for your latest fix of French bread.

Just in the last 2 weeks, people in my office who have eliminated wheat have experienced:

14 lbs weight loss in 14 days

Increased mental clarity, reduced moodiness, deeper sleep

70% reductions in small LDL

More than 300 mg/dl reductions in triglycerides

Relief from chronic scalp rash


I could go on.

All the while, the USDA, the American Heart Association, the American Diabetes Association, the American Dietetic Association, the Surgeon General's Office all advise you to eat more "healthy whole grains."

70% of people (NOT 100%, but the majority) will experience unexpected health benefits by eliminating this corrupt, unphysiologic product called wheat from their diet.

You won't know until you try.

Prototypical Lipoprotein(a)

Here's the prototypical male with lipoprotein(a):



Several features stand out in the majority of men with lipoprotein(a), Lp(a):

Slender--Sometimes absurdly so: BMIs of 21-23 are not uncommon. These are the people who claim they can't gain weight.

Intelligent--Above average to way above average intelligence is the rule.

Gravitate to technical work--Plenty of engineers, scientists, accountants, and other people who work with numbers and/or technical details are more likely to have Lp(a).

Enjoy high levels of aerobic performance--I tell my Lp(a) patients that, if they want to see a bunch of other people with Lp(a), go to a marathon or triathlon. They'll see plenty of people with the pattern among the aerobically-elite.

Are rabid fans of Star Trek.


Okay, I made the last one up. But the rest are uncannilly true, shared by the majority (though not all) men with Lp(a).

Why? I can only speculate that the gene(s) for Lp(a) are closely linked to gene(s) for intelligence of a quantitative kind and some factor that enhances aerobic performance or yields a desirable emotional state with exercise.

Oddly, the same patterns tend not to occur in women in Lp(a). I have yet to discern a personality or body configuration phenotype among the ladies.

Gastric emptying: When slower is better

When it comes to the Internet and Nascar, speed is good: The faster the better.

But when it comes to gastric emptying (the rate at which food passes from the stomach and into the duodenum and small intestine), slower can be better.

Slower transit time for foods passing through the stomach leads to lower blood sugar, lower blood glucose area under-the-curve (AUC), i.e., reduced blood glucose levels over time. Lower postprandial (after-eating) blood sugars can reduce cardiovascular risk. It can lead to a reduction in net calorie intake and weight loss.

Strategies that can slow gastric emptying include:

--Minimizing fluids during a meal--Drinking a lot of fluids, e.g., water, accelerates gastric emptying by approximately 20%.

--Cinnamon--While the full reason to explain Cassia cinnamon's blood glucose-reducing effect has not been completely worked out, part of the effect is likely to due slowed gastric emptying. Thus, a 1/4-2 teaspoons of cinnamon per day can reduce postprandial blood sugar peaks by 10-25 mg/dl.

--Vinegar--Two teaspoons of vinegar in its various forms slows gastric emptying. The effect is likely due to acetic acid, the compound shared by apple cider vinegar, white vinegar, red wine vinegar, Balsamic vinegar, and other varieties.

--Increased fat content--Fat is digested more slowly and slows gastric emptying time, compared to the rapid transit of carbohydrates.

Not everybody should slow gastric emptying. Diabetics with a condition called diabetic gastroparesis should not use these methods, as they can further slow the abnormal gastric emptying that develops as part of their disease, making a bad situation worse.

However, in the rest of us with normal gastric emptying time, a delay in gastric emptying can reduce blood sugar and induce satiety, effects that can work in your favor in reducing cardiovascular risk.
