In the Track Your Plaque program, we aim to stop or reduce your heart scan score.

Recall that, without any preventive efforts, heart scan scores can be expected to increase at the average rate of 30% per year (faster at lower scores, slower at higher scores by a quirk of arithmetic).

I am continually surprised at how often people--that is, people not in the Track Your Plaque program--are often content with what I term "deceleration," or the slowing of plaque growth. In truth, most people are content with deceleration of plaque growth because they simply don't know that plaque continues to grow.

For instance, the BELLES Trial (Beyond Endorsed Lipid Lowering with EBT Scanning (BELLES)), reported in 2005 showed that 650 women participants continued to increase heart scan scores 15% whether they took "high-intensity" statin therapy in the form of Lipitor 80 mg or "low-intensity" statin therapy as pravastatin 40 mg, even though the group taking Lipitor experienced twice the amount of LDL reduction. In other words, heart scan scores continued to increase at the same rate of 15% per year regardless of the intensity of LDL lowering by statin drug.

Another study reported in 2006, Effect of intensive versus standard lipid-lowering treatment with atorvastatin on the progression of calcified coronary atherosclerosis over 12 months: a multicenter, randomized, double-blind trial reported similar results. Of the 471 participants, those taking Lipitor 80 mg per day experienced 27% per year plaque growth (LDL cholesterol 87 mg/dl); those taking 10 mg Lipitor experienced 25% plaque growth (LDL 107 mg/dl). The intensity of statin therapy made no difference on the rate of plaque growth.

In other words, if we are content to sit back and take Lipitor or other statin drug, follow the conventional American Heart Association low-fat, low-cholesterol diet, we will experience somewhere between 15 to 27% annual plaque growth--year after year.

No wonder that conventional advice offered by your friendly neighborhood doctor will avoid (postpone?) only one heart attack in four.

Such is the nature of coronary plaque deceleration: growth is modestly slowed, but is not stopped. Nor is it reversed.

In the Track Your Plaque program, we grade deceleration of plaque growth into three distinct stages out of a total of five. (See Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.)

Why be satisfied with deceleration? Why not aim for a total stop to plaque growth? Why not aim for stage 5 of Track Your Plaque success: reversal?

(For followers of the Heart Scan Blog, below is a re-posting of a recent post. I've moved it up to make it accessible to a number of patients that I asked to look at this post for some conversation about the concept of wheat-free diets.)

TV ads, media conversations, magazine articles, even advice from the American Heart Association and USDA (a la Food Pyramid) all agree: eat more whole grains, get more fiber.

What happens when you follow this advice to add more and more whole grains to your diet? Look around you: People gain weight, they become pre-diabetic and diabetic. Lipids and lipoprotein patterns emerge: increased triglycerides and VLDL, reduced HDL, small LDL. Blood sugar goes up, inflammatory responses are ignited. You feel crumby, cancer risk is increased.

"Official" agencies have urged us to eat more grains, get more fiber and most Americans have complied. We now have a nationwide health disaster that will eventually lead to more people with coronary plaque, more heart disease, more heart attack, more heart procedures.

This is why I've been urging patients to go wheat-free. It has proven an extraordinarily and surprisingly effective strategy for:

1) rapid and profound weight loss
2) raising HDL and reducing triglycerides, VLDL, and small LDL
3) reducing blood sugars, pre-diabetes and diabetes

So here I (re-) post just a sampling of the comments sent by readers of the Heart Scan Blog who have given this idea a try.

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!!

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!

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.

Followers of the Track Your Plaque program know that we advocate periodic fasts to reduce heart disease risk.

I came across an interesting report form an abstract presented at last week's American Heart Association meetings in Orlando:

(Read the report at HeartWire. You will need to register or sign-in.)

In this study, the investigators tried to determine why members of the Church of Jesus Christ of Latter-Day Saints (LDS) tended to have reduced risk of heart disease compared to others in the area but not in the LDS faith. While the reduced risk of heart disease in LDS members had been traditionally attributed to the no smoking policy advocated by the Mormon church, the investigators suspected that there was more to the reduced risk.

Of 515 people interviewed, periodic fasting, whether for religious or other reasons, was found to distinguish people who were less likely to have coronary disease by conventional catheterization (59% vs. 67%). (Since the study was published in only abstract form, it's not clear why all these people underwent heart catheterization in the first place.)

Nonetheless, it's an interesting observation and one consistent with the benefits we see when someone fasts: reduced blood pressure, reduced inflammatory responses, improved lipids and lipoproteins, weight loss.

Fasting can be an especially effective method to gain control over heart disease and coronary plaque if rapid control is desired. In fact, I wonder if the normally year-long process of plaque control that I advocate can be much abbreviated. Fasting, I believe, is a crucial component of rapid control, what I've talked about in Instant Heart Disease Reversal

There's also additional thoughts on fasting in my Heart Scan Blog post, For rapid success, try the "fast" track.

Fasting is not something to fear. It can be an enlightening process that can serve to abruptly sever bad habits, perhaps even turn the clock back on prior dietary and lifestyle excesses. My favorite variation on fasting is to use soy milk (yes, yes, I know! I can already hear the the soy bashers screaming!) as a meal substitute. It is an easy, less dramatic way that still maintains most of the benefit of a full, water-only fast.

Why do stress tests so often fail to detect coronary atherosclerotic plaque? Why do even heart catheterizations--the "gold standard"--fail to disclose the full extent of plaque within the walls of coronary arteries?

We owe much of the explanation of these phenomena to Dr. Seymour Glagov, retired professor of pathology at the University of Chicago.

When studying the coronary arteries of people who died, he observed that people commonly had plenty of atherosclerotic plaque lining the artery wall, yet it did not necessarily impinge on the artery "lumen," or the internal path for blood to flow.

The only time the lumen became obstructed by plaque was when either 1) plaque grew to overwhelming levels and was severe and extensive, or 2) when a plaque had "ruptured," meaning its thin covering had been penetrated and eroded by the underlying plaque tissue like a volcano emerging from the surface and erupting.

This groundbreaking observation, now dubbed "the Glagov phenomenon," explains why someone can have a normal stress test on Tuesday but erupt a plaque on Wednesday.

The Glagov phenomenon also explains why heart scans can detect plaque when both stress tests and heart catheterizations fail to do so. Many physicians will then interpret this to mean that the heart scan was wrong. With the Glagov phenomenon in mind, you can see that the heart scan is not wrong, it is simply detecting coronary atherosclerotic plaque at a stage that is not yet detectable by the other methods.

In the illustration, you can see that the lumen of the vessel is maintained--despite the artery on the left having minimal plaque, the artery on the right containing moderate plaque. If either artery were examined by a test that relies on blood flow--stress test or heart catheterization--both would appear normal. But a test that examines the artery wall, such as a heart scan, would readily detect the artery on the right and probably even the artery on the left.

I am very grateful to Dr. Glagov and his insight into this important process. Otherwise, we might still be floundering around trying to understand the apparent discrepances between these tests that simply provide different perspectives on the same problem.

I dare you: Ask your doctor whether coronary heart disease can be reversed.

My prediction is that the answer will be a flat "NO." Or, something like "rarely, in extraordinary cases," kind of like spontaneous cure of cancer.

There are indeed discussions that have developed over the years in the conventional scientific and medical literature about reversal of heart disease, like Dean Ornish's Lifestyle Heart Trial, the REVERSAL Trial of atorvastatin (Lipitor) and the ASTEROID Trial of rosuvastatin (Crestor). Reversal of atherosclerotic plaque in these trials tends to be small in scale and sporadic.

Of course, the medical literature is swamped with studies that have nothing to do with reversal, like what stent is best, what platelet-inhibiting intravenous drug is best, when should angioplasty or stents be used and when, do implantable defibrillators save lives, improvements in coronary bypass techniques, etc. There are tens of thousands of these studies for every study that focuses on the question of atherosclerotic plaque reversal.

The concept of reversal of heart disease has simply not gained a foothold in the lexicon nor in the thinking of practicing physicians. Heart disease is a relentlessly, unavoidably, and helplessly progressive disease in their way of thinking. Perhaps we can reduce the likelihood of cardiovascular events like heart attack and death with statin drugs and beta blockers. But reverse heart disease ? In your dreams!

We need to change this mentality. Heart disease is a reversible phenomenon. Atherosclerosis in other territories like the carotid arteries is also a reversible pheneomenon. Rather than throwing medicines and (ineffective) diets at you (like the ridiculous American Heart Association program), what if your doctor set out from the start not just to reduce events, but to purposefully reduce your heart's plaque? While it might not succeed in everyone, it would certainly change the focus dramatically.

After all, isn't this the theme followed in cancer treatment? If you had a tumor, isn't cure the goal? Would we accept an oncologist's advice to simply reduce the likelihood of death from cancer but ignore the idea of ridding yourself completely of the disease? I don't think so.

Then why accept "event reduction" as a goal in heart disease? We shouldn't have to. Heart disease reversal--elimination--should be the goal.

Once upon a time, remember how medical information was mysterious, hospitals were places where frightening, inscrutable things happened, diseases were strange maladies that struck without reason, and obtaining information about health was like hunting for buried treasure? The full extent of many peoples' understanding of health came through relatively anemic sources like Readers' Digest. (Remember "I am Joe's Colon"?)

Compare this to what we have now. If I wanted to obtain information about ankylosing spondylitis (a rare genetic disease of the spine), a Google search yields 1.46 million citations. Not all the information, of course, is helpful or relevant, but there's certain to be a bounty of information that far exceeds what you could have uncovered 40 years ago.

Suppose you enter the search phrase "antithrombin III" into your Google search. Citations: over 900,000. (The number of search citations, in fact, exceeds the number of Americans with a deficiency of this blood clotting protein!)

The same is true with heart disease. There was a time, not more than 30-40 years ago, when information about the heart and heart disease was hard to come by. The most you would find were superficial discussions about heart attacks, what chest pain means, descriptions of bypass surgery. Ask your doctor, you'd likely receive a brief, cursory response about how you probably shouldn't worry it.

Even during medical school in the 1980s, I remember struggling to get answers to my questions from faculty during medical school and medical training. It was as if providing too much information would eliminate the advantage superiors wielded over trainees.

The same selfish sentiment, the "I know something you don't know" mentality reminiscent of a schoolboy's "naa na na naa naa!" unfortunately persists. But it is rapidly disintegrating. Soon it will join the junk heap of medical mis-information accumulated over the years (a big pile, to be sure). The internet and, I'll admit (grudgingly), the media, have been responsible for demystifying the formerly mysterious and indecipherable world of health.

You now have, at a moment's disposal, access to an extraordinary array and breadth of health information that was inconceivable just a few years ago.

Times are changing. Doctors no longer hold the monopoly over health information. The public--YOU--are rapidly becoming the arbiters of health, the informed consumers of a soon-to-be retail product called health care, and the increasingly savvy judges of what should join the mainstream path of health. It is all part of this wave of change that I've been advocating: the emerging concept of self-empowerment in healthcare.

Added to the junk heap of health-mistakes-of-years-past will be medical protectionism over health information, heart procedures, drug industry excesses, nutritional mis-information, among others. The demystification of health information will open the floodgates of individual insight into health. It delivers control over your own health destiny straight into your own lap.

Walking the supermarket aisles, you may have lately noticed that numerous new products are appearing sporting "omega-3s" on the label.

Some products simply contain alpha-linolenic acid, a tiny amount of which is converted to the biologically active omega-3s, EPA and DHA. Natural Ovens' Brainy Bagel, for instance, carries a claim of "620 omega-3."

I find this confusing and misleading, since people will often interpret such a claim to mean that it contains 620 of EPA and DHA, similar to two capsules of standard fish oil (1000 mg capsules). Of course, it does NOT. I find this especially troublesome when people will actually stop or reduce their fish oil, since they've been misled into thinking that products like this bread contain active omega-3 fatty acids that yield all the benefits of the "real stuff."

Other products actually contain the omega-3, DHA, though usually in small quantities. Breyer's Smart with DHA is an example, with 32 mg DHA per container.

I find products with actual DHA (from algae) a more credible claim. However, the Center for Science in the Public Interest (CSPI) has looked at the actual contents of DHA in some of these products and found some discrepancies, including amounts of DHA less than the labeled amount and claims of omega-3 wihtout specifying DHA vs. linolenic acid. (It's probably linolenic acid, if it's not specified.)

All in all, the addition of DHA to food products is a nice way to boost your intake of this healthy omega-3. However, keep in mind that these are processed, often highly processed, foods and you will likely pay a premium for the little boost. For now, stick to fish oil, the real thing.

For a brief summary of the CSPI report and a link to the Nutrition Action Newsletter, see Omega-3 Madness: Fish Oil or Snake Oil.

I'm sitting at dinner with two colleagues. One is a cardiology colleague, another an internist who, in addition to practicing general internal medicine, also takes heart disease prevention very seriously. He has, in fact, participated in the Track Your Plaque program and dropped his heart scan score substantially.

"Why don't we see you in the cath lab much?" my cardiology colleague asked me. He was puzzled, since he knew my background in cath lab work from years before, spending day and night doing procedure after procedure. He spends virtually all his days there.

"Well, my patients simply don't have events any more. Heart attacks and angina among people in my program are just about non-existent. They don't have symptoms and they don't have to go to the hospital. I can't remember the last time that I was woken up in the middle of the night for an urgent procedure for one of my patients."

The internist across the table smiled and expressed his agreement. "That's the same thing I'm seeing: No heart attacks, very few if any referrals to cardiologists for procedures. I remember when it was a several times a week thing. Now, almost never. "

Looking at my cardiology colleague, I saw the usual cardiologist reaction: Eyes searching left and right and behind us for something more interesting. Certainly, talking about a virtual cure for coronary heart disease was just too damn dull.

Such is the attitude of 98% of my colleagues: If it doesn't generate a revenue-producing procedure, why bother? Prevention is for general practitioners, the line of thinking goes. "And anyway, I'm too busy doing procedures! I don't ahve time to talk about prevention and health!" Of course, the poor general practitioner is already overloaded with caring for arthritis, flu, diabetes and all the new drugs for diabetes, headaches, vaccinations, diarrhea, and . . .oh, yes, heart disease prevention.

Are cardiologists the enemy? No, of course they are are not. But they often act like they are. Talking to cardiologists is like going to the car dealer with your checkbook out, pen in hand. The salesman gets to write the check himself and you just sign it. Talk to a cardiologist and more often than not you will end up with a heart procedure--whether or not you need it.

Unfortunately--tragically--they often forget what they are supposed to be doing: Taking care of a disease by preventing it. Putting in a defibrillator is not preventing a disease. Putting in three stents, laser angioplasty, and thrombectomy are not ways of preventing a disease.

I'm thankful for my internist friend who sees the light. Coronary heart disease is a an easily measurable, quantifiable, preventable, and REVERSIBLE process for many, if not most, people when provided the right tools. But don't ask your neighborhood cardiologists to give you those tools.

Was torcetrapib’s crash and burn fatal for this class of drug?

At the 2007 American Heart Association meetings in Orlando, Florida, Dr. Philip Barter of Sydney, Australia, presented an update of the ILLUMINATE drug trial for the once-promising drug, torcetrapib, the billion-dollar bet that Pfizer made on its first entry into the new drug class.

You may recall that the crash and burn of Pfizer’s torcetrapib in December 2006 made headlines and prompted enormous disappointment for many patients and doctors who had hoped for a new drug choice to raise HDL cholesterol. Pfizer executives (heads flew!) and investors were also disappointed, anticipating release of a drug that might have become the number one biggest selling drug in the world—ever, surpassing even Lipitor's® $13 billion annual sales.

Torcetrapib is the first among the “cholesteryl-ester transfer protein inhibitors,” or CETP-inhibitors, drugs that block the exchange of cholesterol and triglycerides between HDL and VLDL particles and prevent formation of the unwanted small LDL particles. Preliminary efforts suggested that effects were positively enormous.

However, the 15,000-participant trial was abruptly terminated after 550 days when an excess of deaths were identified among the group taking the experimental drug: 59 deaths in control group; 93 deaths in the torcetrapib group.

In addition, cardiovascular events were 24% greater in the torcetrapib group, numbering 373 compared to 464 in the no-torcetrapib group, including a substantially greater number of heart attacks and hospitalizations. Another surprise came in the way of cause of death among some of the torcetrapib patients, with an excess of deaths due to cancers (twice as many in the torcetrapib group), strokes, and infections.

Why the divergence: enormous improvements in cholesterol values, yet increase in adverse effects including more heart attack? Deeper digging by the principal investigators uncovered unexpected distortions of electrolytes like sodium and potassium. They then re-analyzed blood samples from participants on both sides of the trial and discovered that participants taking torcetrapib experienced significant rise in the blood pressure hormone, aldosterone. This, they surmised, also likely accounted for the 4 mmHg average rise in blood pressure among those taking the experimental drug. (This is the same pathway blocked by blood pressure drugs like ACE inhibitors lisinopril and enalapril, ARBs like losartan.)

Simultaneously (what a coincidence!) with the torcetrapib data, investigators at competing drug manufacturer, Merck, reported encouraging data with their version of CETP inhibitor, anacetrapib. In a phase II FDA trial of 589 patients, anacetrapib reduced LDL-C levels by up to 40% and increased HDL-C up to 139%.

Spokesman Daniel Bloomfield, M.D., of Merck Research Laboratories reported that "The favorable lipid effects seen in this study with multiple doses of anacetrapib were significant, and confirm the continued evaluation of the clinical benefits of CETP inhibitors in the treatment of dyslipidemia." Quick to distinguish this drug from torcetrapib’s track record of dangerous effects on blood pressure, he added that "the decreased LDL-C concentrations, increased HDL-C concentrations and no demonstrable increase in blood pressure seen with anacetrapib are particularly encouraging results of this study."

However, the data reported only an 8 week expereince. Given the experience with torcetrapib, longer term data will obviously be required to assess safety. After Pfizer spent over $1 billion and sacrificed lives to obtain this experience, Merck will need to tread carefully.

It will clearly be many years before we have a confident answer on whether the CETP-inhibitor class of drugs will be a safe choice for correction of cholesterol abnormalities, especially low HDL. Are we helpless until then?

Though CETP inhibitors offer the potential for a one-stop opportunity to raise HDL substantially, there are still many strategies available to raise HDL.

Strategies that raise HDL and are available today include:
• Weight loss—to your ideal weight. A very effective strategy.
• Reduction in processed carbohydrates—like breads, pasta, cookies, pretzels, etc. Note that very low-fat diets reduce HDL. Often a huge effect.
• Fish oil—A small effect, more dramatic when triglycerides are high.
• Niacin—Vitamin B3, the best we have at present. Doses of 500-1500 mg per day raise HDL 20–50%; work with your doctor if you are contemplating niacin. We use this agent everyday and have had great success; good hydration is key to minimize the annoying “hot-flush” effect.
• Dark chocolate—40 grams, or about 2 inches square, a delicious way to squeeze out a little rise in HDL.
• Alcoholic beverages—Red wines are almost certainly the preferred route, rich in flavonoids.
• Exercise—HDL-raising effects vary, but can sometimes be as much as 10–20 mg.
• Other drugs—Though not commonly used for this effect, drugs like pioglitazone (for diabetes and pre-diabetes); fibrates (Tricor® or fenofibrate; Lopid® or gemfibrozil); and Pletal® or cilostazol are occasionally prescribed.
• Vitamin D—You won’t find validation of this effect in any scientific study, but our emerging experience in our heart disease reversal program is suggesting that this neglected nutrient can exert powerful HDL-raising effects. In fact, supplementing vitamin D has made my life much easier.

And, last I checked, none of these HDL-raising strategies are ever fatal.

Joe, a machinist, was frightened and frustrated.

With a heart scan score of 1644 at age 61, his eyes bulged when I advised him that, if preventive efforts weren't instituted right away, his risk for heart attack was a high as 25% per year. Joe had "passed" a stress test, thus suggesting that, while coronary plaque was present--oodles of it, in fact--coronary blood flow was normal. Thus, there would be no benefit to inserting three stents, say, or a bypass operation.

(Illustration courtesy Wikipedia)

"I don't get it, doc. Why can't you just take it out? You know, like Roto-Rooter it out? Or give me something to dissolve it!"

Of course, if there were such a thing, I'd give it to him. But, of course, there is not. It doesn't mean that there haven't been efforts in this direction over the years. Among the various attempts made to "Roto-Rooter" atherosclerotic plaque have included:

Coronary endarterectomy
This is a drastic procedure rarely performed anymore but enjoyed some popularity in the 1980s and 1990s. Coronary endarterectomy was performed during coronary bypass surgery, but few thoracic surgeons performed it. Milwaukee's Dr. Dudley Johnson was the foremost practitioner of this procedure (retired a few years ago after his own bypass operation) with a mortality in excess of 25%. A very dangerous procedure, indeed. The technical hurdle, beyond the tedium and length of time required to remove plaque that had a tendency to fragment, was blood clot formation after tissue was exposed upon plaque removal. I saw many lengthy hospital stays and deaths following this procedure.

Coronary atherectomy
This is an angioplasty-type procedure that has gone through several variations over the years.

In the early 1990s, transluminal extraction atherectomy (TEC) was a technique involving low-rpm drill bits with a suction apparatus that was used to clear soft debris, usually from large coronary arteries or, more commonly, bypass grafts. Then came direction atherectomy, in which a steel housing contained a sharp drill bit that captured atherosclerotic plaque in an aperture along the housing length and stuffed it into a nosecone, retrieved once the device was removed.

Then came high-speed rotational atherectomy in which a diamond-tipped drill bit rotated up to 200,000 rpm and essentially pulverized plaque to flow downstream and, presumably, eventually captured by the liver for disposal. Rotational atherectomy is still in use on occasion. Laser angioplasty, usually using the excimer wavelength, vaporizes plaque. I did plenty of all of these back in the early and mid-1990s.

While all atherectomy procedures sound clever, they are all plagued by the same problem: vigorous return of plaque. Remove plaque, it grows back. There are few instances today in which atherectomy is still performed.

Chelation
This involves a metal-binding, or "chelating," agent like EDTA normally used in conventional practice for lead poisoning. Usually administered IV, some have also advocated oral use. People who use chelation also tend to believe in faith healing and other practices based on faith, not science. There is an international trial that is nearing completion that should provide the final word on whether there is any role to intravenous chelation.

There are numerous other oral treatments that claim a Roto-Rooter-like effect. Nattokinase, for example--an outright, unadulterated, and unqualified scam.

Unfortunately, the helpless, ignorant, and gullible are many. When frightened by the specter of heart disease, there are plenty of people who will willingly pay for the hope provided by clever ads, fast-talking salespeople, and unscrupulous practitioners.

So, Joe, there is no Roto-Rooter for coronary atherosclerotic plaque, at least one that is safe, doesn't involve a life-threatening effort, provides results that endure beyond a few months, and truly works.

The Track Your Plaque program may not be easy. There are obvious common hurdles to adhering to these concepts: obtaining lipoprotein testing, getting intelligent interepretation of the results, persuading your doctor to measure vitamin D blood levels, battling the onslaught of prevailing food propaganda that confuses and misleads. The Track Your Plaque program also requires time, at least a year.

But it's the best program there is. Do you know of anything better?

There is no longer any doubt that lipoprotein(a) is a major causal factor in heart disease:

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

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

But there are two areas of desperate need:

1) Data on effective treatments.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

One ounce of raw almonds (about 23 nuts) contains:

6 grams protein

14 grams fat

6 grams carbohydrate

3.5 grams fiber

For a total of 163 calories per ounce.

(From the USDA Nutrient Database)

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

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

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

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

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

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

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

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

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

Some other observations with almonds included:

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

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

An extraordinary thing happened about 2 1/2 years ago.

While we have been following the Track Your Plaque program for coronary plaque regression for nearly 10 years, about 2 1/2 years ago we witnessed an extraordinary surge in success--bigger, faster, and more frequent drops in heart scan scores.

Up until then, we did witness significant reversal of coronary plaque by heart scan scores. We were planning to publish the data to validate this approach, but then . . .

Heart scan scores starting dropping not just 2%, or 8% . . . but 24%, 30%, 50% and more. Why? I attribute the surge in success to the addition of vitamin D.

Unfortunately, it also meant that the preceding 8 or so years of data lacked experience with supplementing vitamin D. The hundreds of participants in the Track Your Plaque program had not, until then, included vitamin D in their program.

So I decided to start from scratch (from the standpoint of data collection, not for the participants). That also meant that the preceding years of experience went unreported, though even that data far exceeded the results of what is achieved in conventional heart disease prevention.

Thus, the data I presented at the Experimental Biology Proceedings (FASEB 2008) in San Diego this week included only experiences in the group of participants that included vitamin D in their program, with data collected until mid-2007. The number of experiences is therefore modest.

However, the Track Your Plaque experience, as reported, far exceeds any prior experience in coronary plaque regression.

The full abstract will be published in the Track Your Plaque website.

Many people complain about the size of fish oil capsules. Let's face it: They're usually big and kind of smelly.

Women in particular struggle with big capsules. This becomes a real problem when somebody requires high-dose fish oil for treatment of post-prandial (after-eating) abnormalities, high triglycerides, or lipoprotein(a), when 6 or more--occasionally up to the equivalent of 20--standard fish oil capsules are required.

I came across a small capsule alternative for people who struggle with the big capsules. It's a product called Learn from PharmaOmega, a source of super purified fish oil.

The Learn product is actually made for children, since omega-3 fatty acid supplementation has been linked with improved intellectual performance. But the small capsule size is convenient for women and other people who would like to avoid the big standard-sized capsules.

Each capsule is about 60% of the size of a standard fish oil capsule (the smaller capsule in the photo, next to a standard size fish oil capsule), yet contains 375 mg EPA + DHA per capsule, 25% more than standard capsules (which contain 300 mg per capsule). The ratio of of EPA:DHA is a little more heavily weighted towards EPA with a 5:2 ration, compared to 3:1 of standard capsules. The capsules are also faintly orange flavored and non-fishy.

Disclosure: I receive no compensation for discussing or promoting this product.

Jenny provided permission to reprint her very excellent introduction to low-carbohydrate eating for people with diabetes. You can also view the original version on her Diabetes 101 website.

Jenny is a stickler for monitoring the effects of blood sugar. We might take some lessons from her experiences for improving management of people with metabolic syndrome or borderline blood sugars. In other words, monitoring the blood sugar-raising effects of various foods and food portions can provide great feedback on what foods are preferable, what undesirable, given your physiology.

Even if you are not a diabetic, Jenny's discussion is must reading to gain a better understanding of food choices, particularly carbohydrates. Along with seizing control of health, she has also gained deep wisdom in how to best manage this disease and its physiology.

Introduction to low-carb nutrition for diabetics

It's carbohydrates that raise blood sugar.

Sugars and starches, not the fats that dietitians have been warning you about for so long. If you've been testing your blood sugar after meals, you've probably noticed that already and you are starting to understand why a healthy diabetes diet will have to be one that limits carbohydrates to an amount that doesn't push your blood sugar up over the level where you are damaging your body.

But if your previous experience with restricting carbohydrates involved doing a weight loss diet like Atkins or Protein Power, which worked well for you until you crashed off it entirely and gained back all the weight you'd lost, you may be hesitant to embark on another course of dieting that requires some carb restriction.

I've been there myself. I've done the extremely low carb diet Dr. Richard Bernstein recommends for months on end. I did Protein Power for 3 years. And I've gone on the "Eat all the carbs you didn't eat over the past three years all at once" diet, too. The following observations grew out of my 8 years of experience with learning how to make carb restriction work long-term.

Unlike much of what you've read before, there are no scholarly references for this section. It's based entirely on my own observations and the experience of many dozens of people who have participated in online discussion groups devoted to low carb dieting and diabetes.

Weight Loss Diets Usually Fail but Diabetes Diets Can't Afford To Fail

People who adopt a low carb diet to lose weight tend to start out with great enthusiasm, adapt extreme dieting strategies, swear they will never eat another piece of bread or french fry for the rest of their lives, lose some weight, stall out, burn out, and slink back to their old diets, where they gain back all the weight they lost and more.

This is not a surprise. People on any diet, including low calorie and low fat, do the same thing. The body is very resistant to weight loss and deeply buried instincts in our brains do everything they can to maintain our weights, no matter how unhealthy they might be.

But while this pattern of dieting may be tolerable for those who are dieting to shed a few pounds before their class reunion, it spells disaster for those who must change their diet in order to prevent the high blood sugars that result in amputation, blindness, kidney failure and heart attack death.

Low carbing for diabetes means low carbing for life, long after the thrill has worn off of eating that runny brie and steak. Despite the hype in the diet books, it is not easy, simple, and fun. I know only a handful of people who have been able to sustain a low carb lifestyle for more than five years. And that is after years of online participation in low carb groups.

What you'll find below is what I've found works for me. I used a low carb diet to control my blood sugar for more than five years and have gone through the whole cycle, from enthusiasm, to boredom, to burnout, to saying "To hell with it, we've all got to die some time!" to starting all over again determined to avoid the mistakes that sent me round the bend the first time.

How Many Grams of Carbs to Eat? As Many as Allow You to Reach Your Blood Sugar Targets

When people think about adopting a lower carb diet, their first question is almost always, "How many grams of carbs can I eat at each meal?" Most of the diet books will answer that question with a hard and fast number. Atkins, for example, tells you to start out with 20 grams a day. Protein Power starts you at 30 grams. And Dr. Bernstein suggests 6 grams for breakfast and snacks and 12 grams at lunch and dinner.

Adopting these very low carbohydrate limits will control your blood sugar very nicely. But over time, many people find that sticking to a diet this low in carbohydrate becomes impossible. That's why I'm going to ask you to throw away all those diet books and try a new approach to restricting carbs.

What you will do is to try the strategy used by the people from the alt.support-diabetes newsgroup who informally call themselves "The 5% Club" because their A1c test results fall in the 5% range which doctors consider normal: use your blood sugar meter after each meal to determine how many grams of carbs you can eat and still meet a healthy blood sugar target.

You will start out by measuring your blood sugar one and two hours after each meal. Write down what you ate and observe what it did to your blood sugar. If a meal allows you to reach your blood sugar targets, try eating it again on a different day and test it test again, possibly at a later time, to make sure that your good numbers weren't just a result of slow digestion.

If you end up too high after a meal, the next time you eat it, cut back on the portion size of the carbohydrate elements in the meal and test again. Do this until you can hit your targets, or flag the carbohydrate-containing foods in that meal as ones your body can't handle.

What you're doing here is creating what newsgroup activist Alan S. calls, "a low spike diet" rather than a low carb diet. He can achieve normal post meal blood sugars by eating as many as 30 or 40 grams of carbohydrates at a meal. Others will find that they need to eat a lot less than that amount to hit safe post-meal blood sugar targets.

Usually how much carbohydrate you can manage has something to do with your body size. The more you weigh, the less each gram of carbohydrate you eat will raise your blood sugar. Those of us whose weight is less than 150 lbs often find that we can eat between 12 and 20 grams of carbohydrate and still reach normal blood sugar targets without the help of medications, and that we can add perhaps another 10 or 20 grams more, with medications. People who are much heavier can often eat 30 or 40 grams per meal and still reach their blood sugar targets. In general, men can eat more carbohydrates and still reach their targets than can women, again, because of their larger body size.

How to Learn How Much Carbohydrate is in Your Food

To make this system work, it helps if you start to learn how many grams of carbohydrate are in the foods you eat. That way you won't have to test hundreds of foods once you've learned how a representative sample affect you.

The best way to learn how many grams of carbohydrates are in the different foods you eat is to read food labels carefully, invest in a nutritional guide like one of Connie Netzer's books of nutritional information, download nutrition software like LifeForm (http://www.lifeform.com) or use online calculators like Fit Day (http://www.fitday.com). Software and online sites will compute the amount of carbohydrates and other nutrients in your meal for you as long as you know the portion size.

Learn about Portion Sizes!
This brings up an important point: When you estimate how many grams of carbohydrate there are in a portion of food, it is very important to find out if the amount of food on your plate corresponds to the amount in the "one serving" listed on a label, in a book, or in your software.

The best way to do this is to invest in an electronic food scale and to weigh your foods for a few weeks until you get the hang of estimating portion size. You can get a good food scale at a gourmet kitchen shop for $25 to $40 dollars. This food scale may be the best nutritional investment you'll ever make.

Once you start using your scale, you will find that the muffin you bought at the coffee shop weighs 8 ounces, which is fully four times the 2 ounces that most food databases give as "one serving" of a muffin. When you read that a mythical 2 ounce portion of muffin contains 27 grams of carbohydrate you will realize why that 8 ounce coffee shop muffin with its 108 grams of carbohydrates sends your blood sugar into the psycho zone!

With ice cream, when you weigh your ice cream on a food scale, you'll quickly see that the "one portion" listed on the package turns out to be only a few teaspoons' worth. That bowl you've been considering as one portion of ice cream weighs in as four servings or 72 grams of carbohydrate and 600 calories, which may explain its damaging effect on both your blood sugar and your waistline.

This may sound like a lot of work, and when you first start, it is. But after you do it for a few weeks you'll find you have memorized the carbohydrate gram counts and the portion sizes for the foods you usually eat, and once you have tested your blood after eating these portion sizes, you won't have to test every time you eat a favorite meal, because you will know what it is going to do to your blood sugar.

Eating Away from Home

The biggest challenge you'll encounter as you start learning what you can eat will be eating away from home. You aren't going to be able to weigh restaurant foods nor can you look up the nutritional values of many restaurant offerings--though many of the common fast food outlets do provide nutritional information online--though often without listing portion sizes.

That makes it a very good idea to avoid starchy or sugary restaurant foods or, if you do eat them, to eat only a small portion of what you are offered. Measure your blood sugar an hour or two hours after eating if you aren't sure about how a restaurant food will affect you.

Fat and Carbs Eaten Together will Digest Slowly

Foods with a lot of fat in them take longer to digest than those without a lot of fat. This is why pizza and ice cream often give deceptively good readings on your meter. If you test a meal and see a reading that is too good to be true, be sure you test at 3 or four hours after eating.

The Truth About Pasta

Pasta was long recommended to people with diabetes as a food that would not raise blood sugar and you will still see it starring in many cookbooks and magazines intended for people with diabetes.

However, if you test pasta 4 or 5 hours after eating, you may get an unpleasant surprise. This is true with the so-called "low carb" pastas, too. These foods give you excellent readings at one and two hours because they are resistant to digestion so they don't turn into glucose right away. But five hours later, they do break down into glucose and when they do, the 52 grams of carbohydrates found in each 2 ounce serving of pasta will hit your blood stream with a nasty wallop. (Not to mention that you almost need a microscope to see a 2 ounce portion of pasta. Most people's idea of a portion of pasta is closer to 6 ounces--and 156 grams of carbohydrate!)

If you have pasta for dinner and don't see a peak 3 hours later, be sure to check your fasting blood sugar the next morning. You may see the blood sugar rise there, too.

Sugar Alcohol and "Sugar Free" Foods

The sugar alcohol used in so-called "sugar free" foods can also show up in your blood sugar an hour or two after you'd expect to see them, especially the maltitol used in "sugar-free" candy. At least half of the sugar in Maltitol does turn into glucose in your blood stream and it can raise your blood sugar, but the rise is delayed so you may miss it on testing. So if a "sugar free" food seems to be kind to your blood sugar, try testing it an hour or two after your first tests. Erythritol is the one sugar alcohol that usually does not show up in your blood sugar.

Dealing with Limited Blood Testing Supplies

In in ideal world, we'd all have all the testing supplies we needed to control our blood sugar, but in real life blood sugar test strips are very expensive and many insurers sharply limit the number of strips people with Type 2 diabetes can get each month.

Here are some strategies that can help you if your access to strips is limited.

If you only have 50 strips to get you through a month, plan out what you are going to test ahead of time. Pick one of your favorite meals, and test at 1 hour after eating the first time you eat it and 2 hours after eating the second. Do this with a couple different meals and see if there's a pattern as to when you see the highest reading--whether it is at one hour or two. Then choose another meal and test it at the time when you saw the highest reading in the earlier meal. If you ever get a surprisingly low reading, try testing an hour later or earlier, to make sure you aren't missing the peak.

Make the goal of your testing be learning how many grams of carbs you can tolerate in one meal. If you learn that 30 grams is your upper limit, use software and your scale to find portions of other foods that will also clock in at 30 grams or less. Test one or two of these, and if you see the result you expect, you don't have to test every time you eat these foods again.

Wal-mart sells a cheap and effective blood sugar meter with strips that cost one half as much as other vendors. Some drug stores also sell store brand meters with cheaper strips. If you need more strips, consider the $50 you pay for another 100 strips an investment in your health. It's far better to spend that $50 now, than to spend it on expensive doctor bills caused by complications you don't need to develop!

Keep the focus on Achieving your Blood Sugar Goals

By testing after meals, you'll learn how many grams of carbohydrate your own, unique, body can handle. And more importantly, you'll also be able to decide if you are going to be able to control through diet alone, of whether it is time to talk to your doctor about supplementing dietary control with drugs.

Many people are so excited to learn that they can achieve normal blood sugars by cutting way back on carbohydrates that they become zealots for low carb dieting. I've been there and I've done that. But it's important not to get too carried away with a "Carbs are Evil" mentality which makes it a matter of religious zeal never to let evil carbs cross your lips again. Like all conversions this one tends to fade out in time. And as we said at the start of this chapter, your ultimate goal is to maintain your blood sugar targets for the rest of your life. So the safest approach is to get the most blood sugar benefit you can out of restricting carbohydrates, but restrict them to a level you can maintain year in and year out.

Most importantly, I have learned it is best to treat carb restriction as a strategy, one of many, which used in combination with other strategies including medications if needed, can give you normal blood sugars, rather than the One and Only True Way. If you can be flexible and find more than one tool to help you meet your blood sugar targets, you are more likely to be able to maintain those excellent blood sugars for years to come.

Eliminate "Habit Carbs" and Concentrate on "Value Carbs"
When people think about restricting their carb intake they assume this means never eating any of their favorite foods again.

But for many of us, this doesn't have to be true. Why? Because a quick look at your daily carb intake will often reveal that the bulk of the carbohydrates you are eating are what I call "habit carbs." These are the carbs you eat without a second thought because they are there. Not because they taste good. Not because you couldn't live without them. Just because you're in the habit of eating them.

Here is a list of some prime "habit carbs."

Steam table mashed potatoes

Limp french fries

Squashy hamburger buns

Cardboard toast

Cold home fries

Stale boxed cookies

How many of these flavorless, starchy foods are you consuming everyday just because they're there? Probably more than you realize. So before you lift that fork-full to your mouth, ask yourself, "Is this food thrilling me?" If not, put it down. This should go a long way towards getting your carb intake down.

What I'd call "value carbs" are those carb-rich foods that really do mean something to you. I'm not going to lie to you. You are not going to be able to make them the mainstays of your diabetes diet. But by using the strategies describe below, you should be able to eat enough of these foods to keep yourself from feeling deprived--without destroying your health.

Don't Create "Forbidden Foods!"

If you are one of those people who could live happily on Purina People Chow, you can skip what follows. But if food has been important to you, and if you have hitherto had a long and emotionally satisfying relationship with food, or if, like me, baking from scratch was one of your favorite ways to show love and express creativity, restricting your carbohydrate input will mean that a whole lot of what you've been eating (and baking) up until now is suddenly, completely, off limits. I can't eat cake and get a healthy blood sugar level. Even with two different diabetes drugs in my system. I can't eat cake even with an insulin shot before I eat it. I love cake but there is no way I can eat more than a bite or two without seeing very high blood sugars and there is no way I can eat two bites of cake and be happy. The same goes for french fries and Thai noodles.

During the first enthusiastic weeks of exploring carb restriction most people deal with this kind of discovery by coming up with new recipes and finding new, delicious and healthy things they can substitute for old, high carb standards. They appreciate the way cutting way back on c All posts by william-davis

Self-directed health: At-home lab testing

29. March 2009 William Davis (20)

I have a prediction.

I predict that more and more healthcare can and will be obtained directly by the individual--without doctors, without hospitals, without the corrupt profit-at-any-costs modus operandi of the pharmaceutical industry. I predict that, given the right tools, Joe or Jane Q. Public will have the choice to manage his or her own health using tools that are directly accessible, tools that include direct-to-consumer medical imaging (CT scans, ultrasound, MRI, etc.), nutritional supplements (a loosely-defined term, to our advantage), and direct-to-consumer laboratory testing.

Done responsibly, self-directed healthcare is superior to healthcare from your doctor. While no one expects you to remove your own gallbladder, you can manage cholesterol, blood sugar issues, vitamin D, low thyroid, and others--better than your doctor.

As everyone becomes more comfortable with the notion of self-directed health, you will see new services appear that help individuals manage their health. You will see prices for direct-to-consumer medical imaging and lab testing drop due to competition, something that doesn't happen in current insurance-based healthcare delivery. People are being exposed to larger deductibles and/or draw money from a medical savings account and will seek more cost advantages. Such direct-to-consumer competitive pricing will meet those needs. Overall, the presently unsustainable cost of healthcare will decline.

To help accelerate the shift of human healthcare away from conventional paths and divert it towards the individual, we have launched a panel of direct-to-consumer at-home laboratory tests that we are making available on the Track Your Plaque website.

On your own (except in California, which requires a doctor's order or prescription; and NY, the only state in the nation that prohibits entirely), you can now test, in the comfort of your own home with no laboratory blood draw required, parameters including:

--Thyroid tests--Free T3, free T4, TSH
--Lipids
--C-reactive protein
--Vitamin D
--Testosterone
--Progesterone

and others.

As the technology improves, more tests will become available for testing at home. (Lipoproteins are not yet available, but will probably be available within the next few years. That would be an enormous boon to those of us interested in supercharged heart disease prevention and reversal.)

Anyone interested in our at-home testing can just go to the Track Your Plaque lab test Marketplace.

When I first began the Track Your Plaque program around 8 years ago, I saw it as a way for people to learn how to control or reverse coronary atherosclerotic plaque, and I'd hoped that physicians would begin to see the light and become patient advocates in this process. But I have lost hope that most of my colleagues are interested in becoming your advocate in health. They are too locked into the "call me when you hurt" mentality. I now see Track Your Plaque as a way for people to seize control over coronary plaque with minimal assistance from their doctors. Indeed, some of our Members have achieved reduction of their plaque in spite of their doctors.

This is just the tip of the iceberg of what's to come. Brace yourself for a cataclysmic shift in returning health to you and away from those who would profit from your misfortune.

Vitamin D for Peter, Paul, and Mary

27. March 2009 William Davis (15)

Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D.

It means that vitamin D deficiency sustained over many years in:

Peter yields prostate cancer

Paul yields coronary heart disease and diabetes

Mary yields osteoporosis and knee arthritis.

Same deficiency, different diseases.

VDR genotype-determined susceptibility to numerous conditions have been identified, including Graves' thyroiditis, osteoporosis and related bone demineralization diseases, prostate cancer (Fok1 ffI genotype), ovarian cancer, rheumatoid arthritis, breast cancer (Fok1 ff), birth weight of newborns, melanoma and non-melanoma skin cancers, insulin resistance and metabolic syndrome, susceptibility to type I diabetes, Crohn's disease, and neurological or musculoskeletal deterioration with aging that leads to falls, respiratory infections, kidney cancer, even periodontal disease.

Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.

Should we all run out and get our VDR genotypes assessed? So far the data have not progressed far enough to tell us. If, for instance, you prove to have the high-risk Fok1 ff genotype, would you do anything different? Would vitamin D supplementation be conducted any differently? I don't believe so.

Virtually all of us should be supplementing vitamin D at a dose that generates healthy blood levels, regardless of VDR genotype. For those of us following the Track Your Plaque program for coronary plaque control and reversal, that means maintaining serum 25-hydroxy vitamin D levels between 60-70 ng/ml.

As the fascinating research behind VDR genotype susceptibility to disease unfolds, perhaps it will suggest that specific genotypes be somehow managed differently. Until then, take your vitamin D.

Blowup at Milwaukee Heart Scan

26. March 2009 William Davis (20)

A local TV investigative news report just ran a critical report of the goings-on at Milwaukee Heart Scan:

Andy Smith went to Milwaukee Heart Scan. "It passed the smell test like a road kill skunk. I mean it was bad," Smith explained.

Our hidden cameras went inside the high pressure sales pitch. "On a good day I sell eight, nine, 10 people. On a bad day probably three," sales manager Angelo Callegari told us.

What the heck happened?

Let me tell you a story.

Back in 1996, I learned of a new technology called UltraFast CT scanning, or electron-beam tomography (EBT), a variation on the standard CT technology that permitted very rapid scanning, sufficiently rapid to allow visualization of the coronary arteries. Back then, only a few dozen devices had been established nationwide.

But the technology was so promising and the initial data so powerful that I lobbied several hospital systems in town to consider purchasing one of the $1.8 million devices. I was interested in applying this exciting technology for early detection of coronary heart disease in Milwaukee. While administrators from several hospitals listened, they quickly lost interest when they figured out that the scanner was primarily a tool for prevention, and would not be directly useful to increase revenue-generating hospital procedures.

I floundered about for a year, trying to drum up support for obtaining a scanner. The manufacturer of the device, Imatron, put me in touch with a couple from Indiana who were also interested in setting up a scanner and had actually obtained the investment capital to do it. We met and, over the next year, got Milwaukee Heart Scan up and running. I served as Medical Director (but never an investor or owner).

Milwaukee Heart Scan was busy from day one, performing EBT heart scans, as well as CT coronary angiograms as long ago as the late 1990s, virtual colonoscopies, and other imaging tests. We all spent a great deal of time educating the public and physicians on what this technology meant for detection and prevention of disease.

Despite the public's perception that the owners, Nancy and Steve Burlingame, were making a bundle of money, in reality they could barely pay their expenses. As price competition heated up in Milwaukee with the lower-cost competing multidetector scanners cropping up, the Burlingames often did not pay themselves.

My interest was to keep this device afloat. I therefore told the Burlingames that they should pay their bills first--their staff, overhead, the scanner costs, and pay themselves--and not worry about reimbursing me for the (very modest) heart scan interpretation fees. For several years, I read thousands of scans without any compensation. But that was okay with me--I just wanted to be sure this device remained available.

But in 2008, some business people from Chicago contacted Steve Burlingame with prospects of applying a contract model of long-term scanning to patients,i.e.,getting people to sign a several-year contract for discounted imaging. They proposed that Milwaukee Heart Scan offer heart scans for free to get people in the door.

What was peculiar about all this is that none of the four physicians on staff at Milwaukee Heart Scan had any knowledge of these discussions at all, including myself. Personally, I figured something was afoot when I came in to read scans in the summer of 2008. While, ordinarily, there is a single stack of scans to read from the preceding few days, this time there were numerous stacks of scans, hundreds of scans in all. Not a word had been said to me or my colleagues. I quickly figured out (thanks to the staff filling me in) that they had been offering scans for free. Not surprisingly, many people took them up on the offer.

Up until then, I had been readily willing to read heart scans without compensation, provided I could perform scan readings in a modest time commitment every week on the weeks it was my responsibility. But work several hours every day for free? Impossible.

My colleagues and I were deeply upset and concerned and insisted on a meeting with all the people involved, including the Burlingames, who had engineered this new sales program. We expressed serious reservations about what they were doing and insisted that they dramatically scale back the promises being made to people. I personally asked that they fire several of the people they had hired as sales people, given what we thought was unprofessional appearance and behavior.

The Burlingames and their new business partners essentially thumbed their noses at the physicians and ignored our advice. So, of the four physicians (one radiologist, three cardiologists), three of us resigned. (The one remaining cardiologist, I believe, didn't really understand what was going on.)

Apparently, after we left, the hard sales tactics continued. The news media got hold of the story through some understandably disgruntled people, and you know the rest.

The tragedy in all this is that, as wonderful as heart scans are, they don't make money for the people who invest in the technology. In the sad case of Milwaukee Heart Scan, it meant that my former friends, the Burlingames, turned to questionable tactics to make this technology pay.

Make no mistake: Heart scans remain a wonderful medical imaging modality. EBT, in particular, remains a fabulous technology that would--even today--remain the pre-eminent means to image coronary arteries, except that GE (who acquired Imatron some years ago) decided that a more direct path to bigger revenues was to purchase Imatron, then promptly scrap the entire operation, choosing to focus on multidetector technology exclusively.

Don't let the spotty past and petty ambitions cloud the fact that heart scans remain the best way to identify and track coronary plaque. Just don't get tempted by the offer of any free scans "without obligation."

Do you work for the pharmaceutical industry?

24. March 2009 William Davis (30)

In response to my post, Lovaza Rip-off, I received this angry comment:

Very high triglycerides, as you all know, is a very serious and life-threatening condition. Therefore, it is very important that any medication you take for treatment must be FDA proven and scientifically backed. This is true for a few reasons. First, there have been zero studies done to show the effects of Costco brand fish oil pills on patients with high triglycerides. So, you cannot assume, simply because the pills you are taking "claim" to have a certain amount of Omega 3 in the them, that they actually do (supplement labeling is self-submitted by the company, and not regulated by any external or 3rd party agency).

Secondly, the other components in fish oil, and maybe in Costco brand (no one knows because it isn't on the label) can actually inhibit the bioavailablity of Omega 3, most notably, Omega 6. And, nowhere on the Costco label does it tell you how much Omega 6 is in it. We also cannot underestimate the importance of purity with these compounds: a top selling brand of fish oil found stores like CVS was recently recalled because it was found to have large amounts of fire retardant in it! These supplements are NOT regulated by the FDA.

Thirdly, be careful when you compare costs. The cost of hospitalization due to acute pancreatitis (a risk of very high triglycerides) far outweighs the cost of taking Lovaza for even several years. If you have a real disease, you need a real drug. And, until Costco does a prospective long-term clinical trial to show that it lowers triglycerides, it should not be used in place of Lovaza.

Finally, I am a living example of how taking a high-potency supplement form of Omega 3 barely lowered my triglycerides, yet within 2 weeks of being on Lovaza there was a significant difference. I am now at my goal. So, before you knock a company, that, in my opinion, has saved my life, please do your research and do not mislead people into thinking that an Omega 3 is an Omega 3 is an Omega 3. If your insurance covers the most potent, the most pure, and the ONLY proven Omega 3 pill on the market, you should be thankful.

The comment was posted anonymously, so I don't know who it came from. But I can tell who I think it is: Someone who works for the drug industry.

This is a common phenomenon: Large corporations are fearful of the comments that are generated on internet conversations and other media. On the internet, there are actually people whose job it is to do "damage control." I suspect this came from one of them.

Why bother? Surely there are better things to do? Well, that's easy. There are billions of dollars at stake. Lovaza, in particular, is sold on the perception that it is somehow superior. If word gets out that maybe you can achieve the same results at a fraction of the cost . . .

Perhaps the "commenter" should also question whether omega-3 fatty acids can come from eating fish.

As part of my cardiology practice, I provide consultation on complex hyperlipidemias, or unusual lipid abnormalities. I have many patients with something called familial hypertriglyceridemia, a genetic condition that permits triglyceride levels of 500, 1000, even many thousands of mg/dl, levels that, as the anonymous commenter points out, can be dangerous.

I virtually never prescribe Lovaza for these people. In their treatment program, I use simple fish oil supplements, such as that from Costco, Sam's Club, or other retailers. I have not witnessed a single failure in treating these people and reducing triglycerides. People with lesser triglyceride abnormalities likewise respond very nicely to inexpensive fish oil that we can buy at the health food store. (I do rely on useful services like Consumer Reports and www.consumerlab.com to reassure us that no pesticide residues, mercury, or other contaminants are in the brands we use.) Excellent, high-quality fish oil supplements are sold by Carlson, Life Extension, Barlean's, even the Members' Mark brand from Sam's Club.

So, the notion that only prescription fish oil is capable of reducing triglycerides is, in a word, nonsense.

Take that back to your CEO.

Cholesterol effects of carbohydrates

24. March 2009 William Davis (31)

Let's take a hypothetical person, say, a 50-year old male. 5 ft 10 inches, 160 lbs, BMI 23.0. He's slender and in good health.

Our hypothetical man eats a simple diet of vegetables, some fruit, nuts, and meats but avoids processed industrial foods. By macronutrient composition, his diet is approximately 30% protein, 40-50% fat, 20-30% carbohydrate. His starting lipid panel:

Total cholesterol 149 mg/dl
LDL cholesterol 80 mg/dl
HDL 60 mg/dl
Triglycerides 45 mg/dl

His starting lipids are quite favorable (though I don't often see this kind of starting panel nowadays except in athletes). We begin here because this hypothetical man is going to serve as our test subject.

We ask our hypothetical man to load his diet up on "healthy whole grains." He complies by eating whole grain cereals for breakfast, whole wheat toast; sandwiches made with whole grain bread; dinners of whole wheat pasta; snacks of granola bars, whole wheat pretzels and crackers.

Three months later, his lipids show:

Total cholesterol 175 mg/dl
LDL cholesterol 130 mg/dl
HDL 45 mg/dl
Triglycerides 150 mg/dl

You can see that LDL cholesterol has increased, HDL has dropped, and triglycerides have increased. This wave of change is the hallmark of carbohydrate excess, but more specifically of overreliance on wheat products. Beyond his lipid panel, the man has gained 10 lbs, all concentrated in a soft roll around his abdomen, his blood sugar is now in the "borderline range" of between 110 and 126 mg/dl, i.e., pre-diabetic.

If we were to examine this man's advanced lipoproteins (e.g., NMR from Liposcience, or VAP from Atherotech), we would see that there has been an explosive increase in small LDL particles, along with a shift of large HDL to small, and the appearance of multiple abnormal classes of particles called VLDL and IDL (signalling abnormally slowed clearance of dietary by-products from the blood).

Familiar scenario? The "after-carbohydrate" situation is the rule among the people who I first meet who claim to be eating a "healthy" diet, though their patterns are usually much worse, with higher LDL, lower HDL, and much higher triglycerides, an exaggeration of our hypothetical man's abnormalities.

What if our hypothetical man now goes to his conventionally thinking (read "taught medicine by the pharmaceutical industry") physician? What will likely be the advice he receives? Reduce his saturated fat intake, eat plenty of healthy whole grains, take a statin drug.

Although my illustrative man is hypothetical, I've seen this scenario play out many thousands of times. It happens in real life all the time. It is predictable, it is highly manipulable. Sadly, it is rarely recognized for what it is: the result of excess carbohydrates, or what I call "Carbohydrate Intolerance Syndrome."

The misinterpretation of this condition has created 1) an epidemic of diabetes and pre-diabetes, 2) a nation of frustrated obese Americans, 3) a $27 billion per year statin industry, 4) another growth opportunity for the drug industry in diabetes drugs.

Wheat Belly Revisited

23. March 2009 William Davis (24)

Do you have a wheat belly?

When I first coined this phrase back in July, 2007, I had witnessed the phenomenal health effects of wheat elimination in several hundred patients.

In the nearly two years that have passed since my original post, I have witnessed hundreds more people who have done the same: eliminate pretzels, crackers, breads of all sorts, bagels, pasta, muffins, waffles, pancakes, etc.

If anything, I am convinced now more than ever that wheat is among the most destructive foods in the human diet. At least 70% of people who eliminate wheat from their diet obtain at least one, if not several, substantial health benefits.

Now, if I were trying to sell you something, say, an alternative to wheat, then you should be skeptical. If I tell you that drug or nutritional supplement X is great and you should take it, only to follow it with a sales pitch, you should be skeptical.

What am I selling? Nothing. I gain nothing by telling everyone to avoid wheat. In fact, I wish it wasn't true. Wheat foods taste good. Wheat flour makes great comfort foods. In years past, I spent many hours sitting at the bagel shop reviewing papers over a cup of coffee and a bagel. No longer.

So here, back by popular demand, the original Wheat Belly post:

Wheat Belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.

(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

Thank you, Crestor

20. March 2009 William Davis (9)

I'm sure everyone by now has seen the Crestor ads run by drugmaker, AstraZeneca. TV ads, magazine ads, and the Crestor website all echoing the same message:

"While I was busy building my life, something else was busy building in my arteries: dangerous plaque."

While previous drug trials with Mevacor, Pravachol, Zocor, and Lipitor have focused mostly on examining whether the drugs reduced incidence of cardiovascular events, Crestor studies have also focused on effects on atherosclerotic plaque volume. The best example is the ASTEROID trial that demonstrated approximately 7% reduction in plaque volume by intracoronary ultrasound.

So the AstraZeneca decision makers took the leap from cholesterol reduction to plaque reduction.

I'm sure this switch wasn't taken lightly, but was the topic of discussion at many meetings before the decision to make plaque reduction the focus of hundreds of millions of dollars of advertising. After all, billions of dollars are at stake in this bloated statin market.

Ordinarily, I couldn't care less about how the drug manufacturers conduct their advertising campaigns. But this one I paid attention to because the Crestor ads are helping fuel a new way of thinking about coronary heart disease: It's not about the cholesterol; it's about the atherosclerotic plaque that accumulates in arteries.

It's not cholesterol that grows, limits coronary blood flow, and causes angina. It's not cholesterol that "ruptures" its internal contents to the surface within the interior of the blood vessel and causes blood clot and heart attack. It's not cholesterol that fragments from the carotid arteries and showers debris to the brain, causing stroke. It's all plaque.

I took the same leap years ago, though not backed by hundreds of millions of dollars of marketing money. When I first called my book Track Your Plaque, some of the feedback I got from editors included comments like "I thought this was a book about teeth!" Even now, the word "plaque" in the book title and website is responsible for confusion.

But AstraZeneca is helping me clear up the confusion. As the word plaque gains hold in public consciousness, it will become increasingly clear that cholesterol reduction is not what we're after. We are looking for reduction of plaque.

If you are trying to develop an effective means to reduce or reverse coronary heart disease, then there are two simple equations to keep in mind:

Plaque = coronary heart disease

Cholesterol ? coronary heart disease

Plaque is the disease, cholesterol is not. Cholesterol is simply a crude risk for plaque.

While I'm no friend to the drug industry nor to AstraZeneca, some good will come of their efforts.

Supermarkets and buggy whips

17. March 2009 William Davis (17)

Will supermarkets eventually phase out, joining the history books as a phenomenon of the past? Or are supermarkets here to stay, an emblem of the industrialization of our food--easy access to foods that are convenient, suit the undiscriminating masses, stripped of nutritional value despite the prominent health claim on the package front?

Anna left an insightful comment on the last Heart Scan Blog post, Sterols should be outlawed, along with some useful advice on how to avoid this trap for poor health called a supermarket:

I rarely shop in regular supermarkets anymore (farm subscription for veggies, meat bought in bulk for the freezer, eggs from a local individual, fish from a fish market, freshly roasted coffee from a local coffee place, etc.). What little else I need comes from quirky Trader Joe's (dark chocolate!), the fish market, farmer's markets, a small natural foods store, or mail order.

When I do need to go into one of the many huge supermarkets near me, not being a regular shopper there, I never know where anything is, so I have to ramble a bit around the aisles before I find what I'm looking for (and I almost always can grab a hand basket, instead of a trolley cart).

It's almost like being on another planet! There's always so many new products (most of them I hesitate to even call food). It's really a shock to the senses now to see how much stuff supermarkets sell that I wouldn't even pick up to read the label, let alone put in a cart or want to taste. I'm not even tempted by 99% of the tasting samples handed out by the sweet senior ladies in at Costco anymore (only thing I remember tasting at Costco in at least 6 mos was the Kerrygold Irish cheese, because I know their cows have pasture access and it's real food).

What's really shocking to me is how large some sections of the markets have become in recent years. While Americans got larger, so did some sections of the supermarket (hint - good idea to limit the consumption of products from those areas). Meat and seafood counters have shrunk, though. Produce areas seem to be about the same size as always (but more of it is pre-prepped and RTE in packaging.

But the chilled juice section is h-u-g-e! And no, I don't think there is a Florida orange grove behind the cases. Come on, how much juice do people need? Juice glasses used to be teeny tiny, for a good reason. To me it looks like a long wall stocked full of sugar water. Avoiding that section will put a nice dent in the grocery expenses.

The yogurt case is also e-n-o-r-m-o-u-s! Your 115 yo Bulgarian "grandmother" wouldn't know what to make of all these "pseudo-yogurts"! Chock full of every possible variety, but very little fit to eat. The only yogurts I'll look at are made with plain whole milk, without added gums, emulsifiers, or non-fat milk solids, and live cultures (I mostly buy yogurt now and then to refresh my starter culture at home). I can flavor them at home if needed. The sterols are showing up in processed yogurts, too, along with patented new strains of probiotic cultures (I'll stick to my old fashioned, but time-proven homemade lacto-cultured veggies and yogurt instead).

I found the same "cooler spread" in the butter & "spread" section. The spread options were just grotesque sounding. Actually, the butter options weren't much better, as many were blended with other ingredients to increase spreadability, reduce calories or cholesterol/saturated fat, etc. A few plain butters were enhanced with "butter flavor" - say what? And on no package could it be determined if the butter came from cows that were naturally fed on pasture or on grain in confined pens.

Well said, Anna.

There's a huge supermarket about 1 mile away from my house similar to the one Anna describes with aisle after aisle of eye-catching cellophane-wrapped foods. I go there about every 3 or 4 months, and then I only go to get something I need in a pinch. Every time I go, I too am reminded just how many products there are that look more like junk food than real food.

But there's no real money in real food. Who gets rich off of selling green peppers, tomatoes, and eggs?

Supermarkets sell these modern industrial foods because people buy it: Look around you. You don't get to be a 250 lb 5 ft 2 inch-woman by eating too many cucumbers.

Like Anna, I drive an additional several miles to Trader Joes', buy at farmers' markets whenever possible, buy some odds and ends like wine and cheese and raw nuts at specialty stores. I grow my own basil in a big pot I keep in the kitchen and we are just about to start turning over the soil in the back yard for our vegetable garden. I don't need nor do I miss having the choice among 40 different chips, 25 brands of ready-made microwavable dinners, an entire aisle of breakfast cereasl (all of which are virtually the same with different names and labels), or 75 varieties of salad dressing.

The supermarket for me--and I hope for many of you--has become a place rarely frequented, and only for the odd forgotten item. Oh, I forgot the dog chewies the grocery does have--my dogs love them. So perhaps they are good for something after all.

Sterols should be outlawed

14. March 2009 William Davis (10)

While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.

Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.

Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.

The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:

Each Nature Valley Healthy Heart Bar contains 400 mg sterols.

HeartWise orange juice contains 1000 mg sterols per 8 oz serving.

Promise SuperShots contains 400 mg sterols per container.

Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.

MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.

Kardea olive oil has 500 mg sterols per 14 gram serving.

WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.

Texas state representative, Rene Oliveira, has introduced legislation that mandates heart scans for adults in the state of Texas.

Rep. Oliveira

A press release from the SHAPE Society ( Society for Heart Attack Prevention and Eradication) reads:

Assessment of heart attack risk on the basis of traditional risk factors alone such as high cholesterol and high blood pressure and so forth, while useful, misses many who are at high risk and also incorrectly flags some for high risk who are in fact at very low risk of near term heart attack; on the other hand detection of atherosclerosis by non-invasive imaging, as suggested by the SHAPE group, accurately identifies plaque and improves the ability to identify at-risk individuals who could benefit from aggressive preventive intervention while sparing low-risk subjects from unnecessary aggressive medical therapy," said Dr. P.K. Shah, Director of Cardiology at Cedars Sinai Heart Institute in Los Angeles, a leading member of the SHAPE Task Force who is also an active member of the American Heart Association. "Sadly, these vulnerable patients go undetected until struck by a heart attack, because insurance companies don't cover the newer heart attack screening imaging tests."

Rep. Oliveira, whose coronary disease was first uncovered by a heart scan and prompted a bypass operation, states:

"It is about time that we cover preventive screening for the number one killer in Texas, and take action to reduce healthcare costs through preventive healthcare. Right now, we are extending the lives of those who can afford the procedure while hundreds of thousands of Texans with hidden heart disease go undetected because of antiquated thinking. The time has come for this change."

Is this what we've come to? Since practicing physicians are either so entranced by the drug and procedural solutions to heart disease, do we need to resort to heart scan by legislation?

It does indeed appear that we've come to this point. Should this trend catch on, it will surely mean an upfront increase in healthcare costs to cover the expense of heart scans. But in the long run, it will mean reduction in healthcare costs--dramatic reduction--if heart scans prompt effective preventive action.
