In heart disease prevention, shoot for perfection

12. April 2006 William Davis (0)

It really struck me today that it's the people who've chosen to compromise their prevention program who end up with trouble--heart procedures, heart attack, even heart failure.

Take Bob, for example. Bob is 73 years old and had a bypass operation in 2000. The procedure went well and Bob enjoyed 6 years of seemingly trouble-free life. Bob had a seriously low HDL cholesterol for which he as taken a modest dose of niacin, but was unwilling to do much more. His HDL cholesterol was thererefore "stalled" at around 40 mg. (We aim for 60 mg or greater.) We talked repeatedly about the options for increasing HDL but Bob was content with his results. After all, since his bypass operation, he'd felt well and could do all he wanted without physical limitation.

But Bob underwent a stress test for surveillance purposes (which we routinely do 5 or more years after bypass surgery). The test was markedly abnormal with two major areas of poor blood flow to his heart (signalling potential heart attack in future). Bob ended up getting 5 stents to salvage two bypass grafts, both of which showed signs of substantial degeneration.

I've seen this scenario repeatedly: A person is unwilling to go the extra mile to obtain perfection in lipid/lipoprotein patterns, lifestyle changes, and taking the basic, required supplements. Compromises eventually catch up to you in the form of another heart attack, more procedures, heart failure, physical disability, even death.

The message: Don't draw compromises in heart disease prevention. Coronary plaque is a chronic process. It will take advantage of you if you ever let your guard down.

The epidemic of small LDL

11. April 2006 William Davis (0)

Of the patients I saw in my office yesterday, virtually EVERYONE had small LDL.

Small LDL is emerging as an extraordinarily prevalent lipoprotein pattern that drives coronary plaque growth. Previous estimates have put small LDL as affecting only 20-30% of people with coronary disease. However, in my experience in the last few years, I would estimate that greater than 80% of people with measurable coronary plaque have small LDL.

If you have a heart scan score >zero, chances are you have it, too.

I call small LDL a "modern" disease because it has skyrocketed in prevalence recently because of the great surge in inactivity in Americans.

When's the last time you walked to the grocery store and back, lugging two bags of groceries? How many years has it been since you've push-mowed your lawn? All the small conveniences of life have permeated further and further into our activities. Most of us spend the great majority of our day right where you are now--on your duff.

On the bright side, small LDL in most people is reducable by simply getting up and going. But the old teaching of 30 minutes of activity per day is now outdated. This was true when the other hours of your life included physical activities, like housework or a moderately active job. However, if the other 23 1/2 hours of your day are sedentary, then 30 minutes a day won't do it. An hour or more of activity, whether exercise or physical labor of some variety will get you better small LDL-suppressing results.

For most people with small LDL, fish oil and niacin are also necessary to fully suppress small LDL to the Track Your Plaque goal of <10 mg/dl.

A great discussion on vitamin D

10. April 2006 William Davis (0)

If you need better convincing that vitamin D is among the most underappreciated but crucial vitamins for health, see Russell Martin's review of vitamin D and its role in cancer prevention. You'll find it in March, 2006 Life Extension Magazine or their www.LEF.org website at:

http://search.lef.org/cgi-src-bin/MsmGo.exe?grab_id=0&page_id=1308&query=vitamin%20d&hiword=VITAM%20VITAMER%20VITAMERS%20VITAMI%20VITAMINA%20VITAMINAS%20VITAMINC%20VITAMIND%20VITAMINE%20VITAMINEN%20VITAMINES%20VITAMINIC%20VITAMINK%20VITAMINS%20d%20vitamin%20

Our preliminary experience over the past year suggests that vitamin D may be the crucial missing link in many people's plaque control program. We've had a handful of people who, despite an otherwise perfect program (LDL<60, HDL>60, etc.; vigorous exercise, healthy food selection, etc.--I mean perfect)continued to show plaque growth. The rate of growth was slower than the natural expected rate of 30% per year, but still frightening rates of 14-18% per year--until we added vitamin D. All of a sudden, we saw dramatic regression of 7-25% in 6 months to a year.

This does not mean that vitamin D all by itself regresses plaque. I believe it means that vitamin D exerts a "permissive" effect, allowing all the other treatments (fish oil, LDL reduction, HDL raising, correction of small LDL, etc.) to exert their full benefit. So please don't stop everything and just take D. This will not work. However, adding vitamin D to your program on top of the basic Track Your Plaque approach--that's the best way I know of.

MSNBC Report: We need more heart procedures!

10. April 2006 William Davis (0)

A recent headline from MSNBC by Robert Bazell reads:

NEW YORK - Angioplasty, bypass surgery and cholesterol-lowering medications are among the many interventions that have brought a sharp decrease in heart disease deaths in recent years. But, as Dr. Sharon Hayes of the Mayo Clinic points out, there is one big problem.

“The death rates in women have not declined as much as they have in men,” she says.

The piece goes on to suggest that women are getting short-ended in the diagnosis of heart symptoms and heart attack. The solution: More testing to assess the need for procedures like bypass.

This is typical of the device and medication-dominated media consciousness: More procedures, more medication, more devices. Who's paying for advertising, after all? The money at stake is huge. But is this what you want?

Don't be swayed by media reporters with limited understanding of the real issues (at best), consciousness of who's paying for advertising (at worst). Yes, heart disese is often underestimated or misdiagnosed in women. The answer is better detection earlier in life followed by efforts to halt the process--effective, safe treatments for people's benefit, not just profit.

What role cholesterol medication?

10. April 2006 William Davis (0)

A frequent conversation point among my patients, as well as participants in the www.cureality.com program, is "Are cholesterol medications really necessary?"

No, they are not. What IS necessary is to correct all manifest and hidden causes of coronary plaque. Among these causes, in my view, is LDL cholesterol of 60 mg/dl or greater. There are many other causes of coronary plaque--e.g., small LDL particles, unrecognized hypertension, Lp(a), hidden diabetic patterns, etc.--but reducing LDL to 60 mg is still an important part of a plaque-reversing effort.

Insofar as we wish to get LDL to this goal, the statin cholesterol drugs like Lipitor, Zocor, Crestor, etc. may play a role. However, they should only be considered after a full effort dietary program is pursued. Don't follow the American Heart Association's diet unless you want to fail. It's nonsense.

For a more detailed discussion of how to use nutrition and nutritional supplements to reduce LDL cholesterol, go to www.lef.org, the website for the Life Extension Foundation. I wrote an article for their magazine called "Cholesterol and Statin Drugs: Separating Hype from Reality". You'll find the article at http://search.lef.org/cgi-src-bin/MsmGo.exe?grab_id=0&page_id=1295&query=davis%20cholesterol%20natural&hiword=CHOLESTEROLA%20CHOLESTEROLS%20DAVI%20DAVID%20DAVIE%20DAVIES%20DAVIN%20DAVIO%20DAVISON%20DAVISS%20DAVIT%20NATURALBASED%20NATURALES%20NATURALIZED%20NATURALLY%20NATURALS%20NATURE%20NATURES%20cholesterol%20davis%20natural%20.)

Can your plaque-reversal efforts succeed without statin drugs? It depends on your causes. For instance, someone with small LDL and Lp(a) only may do great on our basic program and then add niacin. Unfortunately, another person with a starting LDL cholesterol of 240 mg/dl--sky high--will have more success with these drugs.

Believe me, I am no blind supporter of drug companies and their flagrantly profit-seeking practices which, in my view, are cut-throat, shoving anyone and anything out of their way to increase profits and market share. I share many of Dr. Dave Warnarowski's views on how vicious their tactics can be; see his recent Blog post at http://www.drdavesbest.com/blog/ called "I smell a rat".

Nonetheless, the deep and well-funded research of the pharmaceutical industry does yield some useful tools. You don't have to love the insect exterminator, but if your house is being eaten by termites, his services can be useful. Same thing with these drugs. Useful--not the complete answer, not even close, but nonetheless useful in the right situations. Sometimes antibiotics are necessary, even life saving. That's how cholesterol drugs are, too.

Take it all in the proper perspective. Your goal is not cholesterol reduction, per se, but plaque control, preferably reversal.

Supplement Mania!

9. April 2006 William Davis (3)

Ever hear of "polypharmacy"? That's when someone takes too many medicines. People will have lists of 15-20 prescription medicines, for instance, with crazy interactions and oodles of side-effects.

Well, how about "poly-supplments"? That's when someone takes a large number of nutritional supplements.

Let me tell you about a 45 year old man I met.

In an effort to rid himself of risk for heart disease that he felt was likely shared with his family (brother and father diagnosed with heart attacks in their late 40s), Steve followed a program of nutritional supplementation. You name it, he took it: hawthorne, anti-oxidant mixtures, vitamins C, E, B-complex, saw palmetto, 7-keto DHEA, velvet deer antler, gingko biloba, policosanol, chronium picolinate, green tea, pine bark extract, St. John's Wort, CoEnzyme Q10, papain and other digestive enzymes...He became a distributor for a nutritional supplement company to allow him to afford his own extraordinary program.

To satisfy himself that he had indeed "cured" himself of heart disease, he got himself a CT heart scan. His score: 470, in th 99th percentile. Steve's heart attack risk based on this score was around 10% per year. High risk, no question.

For weeks after his scan, Steve admitted walking around in a daze, not knowing what to do. Years of telling himself that he had effectively dealt with his heart disease risk, now all down the drain.

When we met, I persuaded him that to think that this collection of supplements would reverse heart disease was magical thinking. We trimmed his list down to the essentials and got him on the right track.

Heart disease is controllable and reversible, but not this way. Don't fool yourself into thinking that some collection of supplements will be enough to stamp out your heart disease risk. Just like taking an antibiotic when you don't have an infection achieves nothing, so does taking the wrong supplements.

What does heart scanning mean to you?

8. April 2006 William Davis (0)

CT heart scans can mean different things to different people.

What does a heart scan mean to you? There are several possibilities:

1) A way of reducing uncertainty in your future.

2) A tool to crystallize your commitment to health.

3) A device to help you track how successful your heart disease prevention program is.

4) A trick to get you in the hospital.

5) A moneymaking tool for unscrupulous physicians hoping to profit from "downstream" testing, particularly heart catheterizations.

Like anything, heart scans can be used for both good and evil. How can you be sure that your heart scan is put to proper use--for your benefit and not someone else's profit?

Simple: Get educated. Understand the issues, be armed with informed questions.

If, for instance, you're a 55-year old female with a heart scan score of 90, active without symptoms, and you're told to have a heart catheterization right off the bat---run the other way. This is bad advice. A heart procedure like catheterization at this score in an asymptomatic woman is very rarely necessary. That decision can only be made after a step-by-step series of decisions are made by a truly interested, unbiased party. (A stress test is almost always required in this situation before the decision can be made to proceed with a catheterization.)

Unfortunately, in 2006, getting unbiased advice from your doctor is still a struggle. That's why we started Track Your Plaque---unbiased information, uncolored by drug or device company support, with an interest in the truth.

Coronary disease is drying up!

7. April 2006 William Davis (1)

I had an interesting conversation with a device representative this morning. He was a sales representative for a major medical manufacturer of stents, defibrillators, and other such devices for heart disease.

Since I'm still involved with hospital heart care and cardiac catheterization laboratories, this representative asked me if I was interested in getting involved with some of the new cardiac devices making it to market over the next year or two. "The coronary market is drying up, what with coated stents and such. We've got to find new profit sources."

Well, doesn't that sum it up? If you haven't already had this epiphany, here it is:

HEART DISEASE IS A PROFITABLE BUSINESS!

Why else can hospitals afford billboards, $10 million dollar annual ad campaigns, etc.? They do it for PROFIT. Likewise, device and drug manufacturers see the tremendous profit in heart disease.

The representative's comments about the market "drying up" simply means that the use of coated stents has cut back on the need for repeat procedures. It does NOT mean that coronary disease is on the way out. On the contrary, for the people and institutions who stand to profit from heart care, there's lots of opportunity.

Track Your Plaque is trying to battle this trend. Heart disease should NOT be profitable. For the vast majority of us, it is a preventable process, much like house fires and dental cavities.

Mammogram for your heart

6. April 2006 William Davis (0)

With the booming popularity of "64-slice CT scans", there's a lot of mis-information about what these tests provide.

These tests are essentially heart scans with added x-ray dye injected to see the insides of the arteries. However, to accomplish this, a large quantity of radiation is required. In addition, the test is not quantitative, that is, it is not a precise measure that can be repeated year after year.

It is okay to have a 64-slice CT coronary angiogram. It is NOT okay to have one every year. That's too much radiation. However, a heart scan can be repeated every year, if necessary, to track progression or regression. Once stabilization (zero change) or reduction is achieved, then you're done (unless your life takes a major change, like a 20 lb weight gain).

The tried-and-true CT heart scan is the gold standard--easy, inexpensive, precise, and repeatable. Not true for 64-slice angiograms.

Is your doctor using "leeches"?

4. April 2006 William Davis (0)

What if you went to your doctor for a problem and he/she promptly placed leeches on your body?

Yeccchhhh! Would you go back? I'd bet that you'd run the other way as fast as your bleeding legs could take you. Outdated health practices like "bleeding" are outdated for good reason.

Then why would you allow your doctor to approach your heart disease prevention program by checking cholesterol and then waiting for symptoms to appear? That miserable approach leads to tragedy and death all too often--ask Bill Clinton! He might as well have had leeches!

Don't allow your doctor's ignorance or disinterest impede your prevention program. Get your coronary plaque measured, then attack it from all sides by knowing all causes, hidden and obvious. That's why Track Your Plaque is such an effective program.

I often wonder why more doctors aren't using this unbelievably powerful approach to deal with heart disease. But when I see colleagues implanting stents, defibrillators, and the like for many thousands of dollars per patient, the answers are obvious. Given a choice of a rational, effective program of prevention that pays the doctor a few hundred dollars for his time, versus $2000 to $10,000 for a procedure, you can see that the temptation is irresistible for many physicians.

One bite or many mouthfuls

6. January 2007 William Davis (0)

A reader brought this beautiful series of food photos to my attention:

http://www.wisegeek.com/what-does-200-calories-look-like.htm

It's simply a graphic display of what 200 calories of various foods look like. You'll note that vegetables and fruits permit large servings to yield 200 calories. Processed foods, on the other hand, require very little to tally up the same calorie load. In particularly, look how little in the way of wheat products are required to match that amount.

Heart scan curiosities #4

5. January 2007 William Davis (2)

Here's an interesting example of a 63-year old man with a heart scan score of 112. However, his aortic valve was also severely calcified (loaded with calcium). In other words, the normally flexible and mobile "leaflets" of the aortic valve were coated with calcium and other tissues that interfere with its free motion. The aortic valve is the starburst white in the center of the heart.

This is what the aortic valve should look like on a CT heart scan--you shouldn't see it at all.

The first man with the calcified valve will unfortunately require a new prosthetic aortic valve sometime in his future. This is usually determined with the help of an ultrasound, or echocardiogram, a better test for assessment of the aortic valve (though useless for detection of coronary plaque).

It's my suspicion that chronic and longstanding deficiency of vitamin D is among the factors that contribute to the abnormal deposition of calcium on the aortic valve. We desperately need more data on this. Nonetheless, perhaps this adds yet another reason to 1)get a CT heart scan, and 2) bring your vitamin D blood level to normal. (We aim for 50 ng/ml year round.)

Fish oil and the perverse logic of hospitals

4. January 2007 William Davis (6)

Hospitals are now starting to carry prescription fish oil, known as Omacor, on their formularies. It's used by some thoracic surgeons after bypass surgery, since fish oil has been shown to reduce the likelihood of atrial fibrillation (a common rhythm after heart surgery).

Why now? The data confirming the benefits of fish oil on atrial fibrillation has been available for several years.

It's now available in hospitals because it's FDA-approved. In other words, when fish oil was just a supplement, it was not available in most hospitals. Whenever I've tried to get fish oil for my patients while in hospital, you'd think I was trying to smuggle Osama Bin Laden into the place. The resistance was incredible.

Now that FDA-approved Omacor is available, costing $130 dollars per month for two capsules, $195 for the three capsule per day dose for after surgery, all of a sudden it becomes available. Why would this irrational state of affairs occur in hospitals?

Several reasons, most of which revolve around the great suspicion my colleagues have towards nutritional supplements. In addition, there's the litigation risk: If something has been approved by the FDA, their stamp of endorsement provides some layer of legal protection.

However, I regard those as pretty weak reasons. I am, indeed, grateful that fish oil is gaining a wider audience. But I think it's absurd that it requires a prescription to get it in many hospitals. Imagine, as the drug companies would love, vitamin C became a prescription agent. Instead of $3, it would cost far more. Does that make it better, safer, more effective?

Of course, no drug sales representative is promoting the nutritional supplement fish oil to physicians nor to hospitals. I now see people adding the extraordinary expense of prescription fish oil to their presription bills.

In my view, it's unnecessary, irrational, and driven more by politics and greed than actual need. Take a look at the website for Omacor (www.omacorrx.com). Among the claims:

"OMACOR is the only omega-3 that, along with diet, has been proven and approved to dramatically reduce very high triglycerides..."

This is a bald lie. Dozens of studies have used nutritional supplement fish oil and shown spectacular triglyceride-reducing effects.

Their argument against fish oil supplements:

"Dietary supplements are not FDA-approved for the treatment of any specific disease or medical condition. Get the Facts: nonprescription, dietary supplement omega-3 is not a substitute for prescription OMACOR."

Does that make any sense to you? Should you buy a GM car because only GM makes genuine GM cars? This is the silly logic being offered by these people to justify their ridiculous pricing.

How about: "The unique manufacturing process for OMACOR helps to eliminate worries about mercury and other pollution from the environment."

Funny...mercury in fish tends to be sequestered in the meat, not the oil. Independent reports by both Consumer Reports and Consumer Lab found no mercury, nor PCB's, in nutritional supplement fish oil. But just suggesting a difference without proving it may be enough to scare some people.

Just because something is used by a hospital does not make it better. The adoption of fish oil is hospitals is a good thing. Too bad it has to add to already bloated health care costs to enrich some drug manufacturer.

Repent for past sins

2. January 2007 William Davis (0)

If the food temptations of the holidays got the best of you, and you're now 5, 10, 15 lbs or more over your pre-holiday weight (our record is 18lbs!), then it's time for serious action.

One easy method to regain the control you may have lost is to pick some period, say, 3 days. During those three days, eat nothing but vegetables--no breads, meats, dairy products, certainly no cookies, cakes, pasta, etc., not even fruit. Follow this routine and weight drops rapidly. Vegetables are wonderful but sometimes boring, so use healthy condiments to spice them up: mustards (hot, brown, yellow, horseradish); healthy salad dressings, which are olive or canola oil-based; salsas, a fabulous garnish with no nutritional downside whatsoever; pesto; tapenades; horseradish added to other condiments or even by itself (wasabi).

Of course, fasting in one of its several variations is another rapid method to regain control. My favorite is to use soy milk in a modified fast, usually 4-6 glasses of a low-fat, low-sugar soy milk per day, along with plenty of water. (Please refer to the precautions detailed in the recent Track Your Plaque Special Report, Fasting: Fast Track to Control Plaque , particularly if you fast 5 days or longer or take blood pressure or diabetic medication.)

Of course, yo-yoing your weight--up during the holidays, down after their conclusion--is not good for you. It does raise the likelihood of diabetes, not to mention cultivate the patterns that contribute to coronary plaque growth, especially small LDL. But if temptation got out of control and you need to regain lost ground, these two strategies work fabulously well for most people.

If you've gained, say, 10 lbs during the holidays, but simply resume your usual habits, chances are you won't lose the weight. Year after year, this can add up to an enormous weight gain. The time to act is now. It's easier to lose the 10 lbs of weight you gained recently, rather than the 50 lbs you've stacked up over the past 5 years.

Wheat-free 2007

1. January 2007 William Davis (4)

Long ago, most of us made the change of reducing saturated fat in our diet. Few people now rely on butter (despite the idiotic butter vs. margarine controversy), full-fat dairy products, fried foods, and greasy meats. That's a healthy change, since saturated fat has conclusively been tied to various cancers, high blood pressure, rise in LDL, and is calorie-dense.

But if there were just one change you were to make beyond a reduction in saturated fat, a change that would translate into dramatic health benefits, it would be a drastic reduction, even elimination, of wheat products.

People do indeed eat enormous quantities of wheat flour-containing products. U.S. per capita consumption of wheat flour was 110 pounds in the early 1970s, and rose to 141 pounds in 1991. It's even higher now. 20% or more of most people's caloric intake every day is provided by wheat flour products.

Wheat containing foods are tasty and convenient. Witness the popularity of bagel shops, the goodie counter at Starbuck's, the proliferation of crackers, breads, and breakfast cereals at the grocery store. Patients are horrified when I suggest that they find a substitute for the sandwiches they eat every day. Even Mom said they were okay!

You're unlikely to hear much about this from the popular press. The wheat industry is enormous and exerts extraordinary clout, just like the drug industry. Texas alone farms 6 million acres of wheat, yielding over $2 billion for the state's economy. The "wheat chain" is complex and far-reaching: growers, processors, food manufacturers, the transportation industry, retailers, chemical producers, and on and on. Wheat futures are traded on the Chicago Board of Trade. Wheat is a major export industry for the U.S.

Of course, these are not evil people, intent on corrupting your health. In fact, most of them are probably working under the perception that they are raising a healthy product. The point is that the notion that wheat is healthy is deeply entrenched in the minds and economy of the U.S. Don't expect to hear unbiased commentary on the health effects of wheat products from most media sources.

What can you expect if you sharply reduce or eliminate wheat? The majority of people:

--Feel like a cloud has been lifted from their thinking.
--Don't experience the afternoon blah or tired feeling after lunch.
--Lose weight, sometimes substantial quantities.
--Raise HDL.
--Reduce small LDL.
--Reduce triglycerides, particularly if they start >100 mg/dl.
--Reduce blood sugar.

The reduction in small LDL can be especially impressive.

For most people, reducing or eliminating wheat is a sacrifice, a major change in food choices and even a loss of convenience. But the health benefits for most people can be dramatic.

Is vitamin D a "vitamin"?

29. December 2006 William Davis (5)

Vitamins are crucial participants in the body's reactions and are obtainable from food. Vitamin C, for example, comes from citrus fruits and vegetables. Vitamin K comes from green vegetables. The B vitamins are found in meats, soy, dairy products, and grains. Vitamin A comes from carrots, squash, and other orange and green colored vegetables.

How about vitamin D? What foods contain vitamin D? The list includes:

Food International Units(IU) vitamin D per serving

Cod liver oil, 1 Tablespoon 1,360
Salmon, cooked, 3½ ounces 360
Mackerel, cooked, 3½ ounces 345
Tuna fish, canned in oil, 3 ounces 200
Sardines, canned in oil, drained, 1¾ ounces 250

Milk, nonfat, reduced fat, and whole, vitamin D fortified, 1 cup 98
Margarine, fortified, 1 Tablespoon 60
Pudding, prepared from mix and made with vitamin D fortified milk, ½ cup 50
Cheese, Swiss, 1 ounce 12

Ready-to-eat cereals fortified with 10% of the DV for vitamin D, ¾ cup to 1 cup servings (servings vary according to the brand) 40

Egg, 1 whole (vitamin D is found in egg yolk) 20
Liver, beef, cooked, 3½ ounces 15

(Modified from the Office of Dietary Supplements, National Institutes of Health)

You'll note that the only naturally-occurring food sources of vitamin D are the modest quantities in fish, egg yolks, and liver. All the other vitamin D-containing foods like cereal, milk, and other dairy products have vitamin D only because humans add it.

It takes me (personally) 6000 units of vitamin D per day to bring my blood level to an acceptable 50 ng/ml. To obtain this from eating salmon, I would have to eat 58 ounces, or 3 1/2 pounds of salmon--every day. Or, I could eat 30 cans of tuna fish.

If I didn't want to eat loads of fish every day, I could drink 60 glasses of milk every day. After I recovered from the diarrhea, my vitamin D might be adequate, provided the milk indeed contained the amount stated on the label (which it often does not when scrutinized by the USDA).

If vitamin D is a vitamin, how are humans supposed to get sufficient quantities? I don't know anybody who can eat 3 1/2 lbs of salmon per day, nor drink 60 glasses of milk per day. But aren't vitamins supposed to come from food?

The problem is that vitamin D is not really a vitamin, it's a hormone. If your thyroid hormone level was low, you'd gain 20, 30, or more pounds in weight, your blood pressure would skyrocket, you'd lose your hair, become constipated, develop blood clots, be terribly fatigued. In other words, you'd suffer profound changes. Likewise, if thyroid hormone levels are corrected by giving you thyroid hormone, you'd experience profound correction of these phenomena.

That's what I'm seeing with vitamin D: restoration of this hormone to normal blood levels (25-OH-vitamin D3 50 ng/ml) yields profound changes in the body.

If there's one thing that I've come across lately that packs extraordinary potential to help us in reducing heart scan scores, it's the vitamin--sorry, the hormone--cholecalciferol, or D3.

Heart scan curiosities 3

28. December 2006 William Davis (0)

Note the shape of the chest in this 64-year old man. The front of his chest (upper portion of scan) is concave. In other words, if you were looking at this man (shirtless, of course) face to face, his chest would bow inward, rather than the usual outward configuration. The official name for this is "pectus excavatum".

Compare this to the normal chest in the second image, in which the chest is convex. Face to face, the chest would bow slightly outward.

What does it matter? The pectus excavatum in and of itself has no importance, just a curiousity. (I personally find this surprising, given the fact that the heart actually appears squashed by the sternum, or chest wall.) However, it is commonly associated with a "floppy" mitral valve (also called mitral valve prolapse), a common congenital disorder of the mitral valve often accompanied by a slender build, loose joints, and even a nervous disposition. Occasionally, in its more severe forms, the aorta is also enlarged. (This man's aorta is not enlarged.)

So, while we can't actually visualize the mitral valve by a CT heart scan, we can surmise that he likely has a floppy mitral valve, is slender, is probably a nervous sort, and has long limbs with loose joints. He probably required braces as a child, since many people have a phenemenon of "crowded teeth". The roof of his mouth, or hard palate, probably unusually high up in the mouth. He probably has a "weak chin", meaning a less prominent protuberance of his chin. His fingers and toes are likely unusually long and slender.

It could mean that some attention and exploration of how floppy his mitral valve might be could be useful, e.g., an ultrasound or echocardiogram. He might even require oral antibiotics at the time of any oral or some gastrointestinal procedures, since floppy valve are more susceptible to blood infections when potentially "dirty" orifices are instrumented.

All that from a heart scan!

Gratitude

24. December 2006 William Davis (2)

The holidays and the end of the year may be a good time to reflect on how grateful we should be for having the freedom to discuss the ideas we share on this Blog, the Track Your Plaque website, online and offline.

Although I rant and rave against the status quo in heart disease, the shameful profiteering of my colleagues and hospitals, the cut-throat marketing practices of drug and device manufacturers, I am truly grateful that, in the U.S., I have the extraordinary freedom to say these things. You have the freedom to agree or disagree and none of us pays a price for truth.

I've been reflecting myself a great deal on this idea of happiness and gratitude being a critical component of coronary plaque regression and dropping your heart scan score. (See The Heart Scan Blog from earlier this week.) The more I think about this, the more I think that it is indeed true: Harboring anger and resentment, regrets, irritability, all those petty emotions that most of us know are not good for us, erode our chances for success in dropping your heart scan score.

We could rationalize it this way: Anger and other negative emotions are adrenaline-driven states, also characterized by activation of the "sympathetic" nervous system. (Despite its name, the sympathetic system is not sympathetic, as in compassionate; its the "fight-or-flight" activator that accelerates heart rate and blood pressure.)

Happiness, contentment, and gratitude are "parasympathetic" states characterized by slower heart rates, deeper respiration, greater variation in beat-to-beat heart rates (a powerful predictor for health and the basis for the HeartMath program of Lew Childre), lower blood pressure, and even a subtle change in brain waves. In other words, happiness is not just a mental and emotional state, it is a constellation of physical phenomena.

Even though I pick on Dr. Dean Ornish for his stubborn adherence to the outdated low-fat mantra, I do agree with him on the value of happiness. His book, Love and Survival, articulates this concept. Ornish has even said on several occasions that it wasn't the diet that was most important but the connection and warmth that was created by the comraderie created by participation in the Ornish Program group sessions.

I am personally grateful that the concepts I promote are gaining a following and that I can say so without fear of prosecution. I am grateful that Track Your Plaque followers are not just sharing our concepts, but obtaining genuine and powerful health advice that will help keep them home and healthy, away from hospitals, procedures, and the dangers of heart disease.

I hope you share in my gratitude and are thankful for all the truly wonderful things that surround us. I wish you all a wonderful holiday and long, healthy life filled with gratitude.

A Track Your Plaque failure

23. December 2006 William Davis (0)

We recently had a man suffer a heart attack after beginning the program. Let me tell you the details.

Jerry's heart scan score 781, age 53. Multiple lipoprotein abnormalities: HDL 32 mg/dl, triglycerides 279 mg/dl, nearly all of his LDL was in small particles with an "effective" LDL (LDL particle number), and very high IDL. So Jerry added fish oil 6000 mg per day, niacin, and vitamin D to the statin drug prescribed by his primary physician. Jerry added oat bran, ground flaxseed, and tried to eat fish at least once per week.

However, Jerry continued to smoke. He'd smoked for 40 years (!), up to 2 packs per day, and just reasoned that it was too late to quit. He also continued to indulge in the packaged, processed foods that were part of his convenience story business.

Jerry's stress test was normal--no chest pain, normal EKG, normal images of blood flow, though he was somewhat breathless, likely from his lung disease from smoking.

Two months into his program, he abruptly experienced severe crushing pain in his chest. Because he was traveling, he ended up in a small local hospital. A failed angioplasty led to urgent coronary bypass surgery.

Jerry's alive. Now he's a non-smoker. He's got the pursed lips and peculiar breathing pattern that smokers get, but he's breathing.

Lesson: In the face of the most powerful program for heart disease known, it can still be overpowered by Twinkies, Hoho's, pretzels, chips--and cigarettes.

The new year is approaching. Be grateful for another year of healthy life and commit to a new year of even greater health. If you're a smoker, there's no choice: you've got to quit.

Are you more like a dog or a rabbit?

Dr. William Roberts, editor of the American Journal of Cardiology and cardiovascular pathologist, is a perennial source of clever ideas on heart disease.
In a recent editorial, Dr. Roberts comments:

"Because humans get atherosclerosis, and atherosclerosis is a disease only of herbivorers, humans also must be herbivores. Most humans, of course, eat flesh, but that act does not make us carnivores. Carnivores and herbivores have different characteristics. (1) The teeth of carnivores are sharp; those of herbivores, flat (humans have some sharp teeth but most are flat for grinding the fruits, vegetables, and grains we are built to eat). (2) The intestinal tract of carnivores is short (about 3 times body length); that of herbivores, long (about 12 times body length). (Since I am 6 feet tall my intestinal tract should be about 60 feet long. As a consequence, if I eat bovine muscle [steak], it could take 5 days to course through those 20 yards.) (3) Body cooling for carnivores is done by panting because they have no ability to seat; although herbivores also can pant, they cool their bodies mainly by sweating. (4) Drinking fluids is by lapping them for the carnivore; it is by sipping them for the herbivore. (5) Vitamin C is made by the carnivore's own body; herbivores obtain their ascorbic acid only from their diet. Thus, although most human beings think we are carnivores or at least conduct their lives as if we were, basically humans are herbivores. If we could decrease our flesh intake to as few as 5 to 7 meals a week our health would improve substantially."

You can always count on Dr. Bill Roberts to come up with some clever observations.

I think he's right. Some of the most unhealthy people I've known have been serious meat eaters. Most of the vegetarians have been among the healthiest. (I say most because if a vegetarian still indulges in plenty of junk foods like chips, crackers, breakfast cereals, breads, etc., then they can be every bit as unhealthy as a meat eater.)

Should you become a vegetarian to gain control over coronary plaque and other aspects of health? I don't believe you have to. However, modern livestock raising practices have substantially modified the composition of meats. A steak in 2006, for instance, is not the same thing as a steak in 1896. The saturated and monounsaturated fat content are different, the pattern of fat "marbling" is different, the lean protein content is different. Meat is less healthy today than 100 years ago.

Take a lesson from Dr. Roberts' tongue-in-cheek but nonetheless provocative thoughts. Pardon me while I chew on some carrots.

Fish oil: What's the difference?

10. December 2010 William Davis (27)

Ultra-purified, pharmaceutical grade, molecularly distilled. Over-the-counter vs. prescription. Gelcap, liquid, emulsion.

There's a mind-boggling variety of choices in fish oil today. A visit to any health food store, or any "big box" store for that matter, will yield at least several, if not dozens, of choices, all with varying and often extravagant claims of purity and potency.

So what's the real story?

Given the analyses conducted over the years, along with my experience with dozens of different preparations, I believe that several conclusions can be reached about fish oil:

Fish oil is free of contamination with mercury, dioxin, PCBs, or furans. To my knowledge, only one fish oil preparation has been found to have a slight excess of PCBs. (This is different from cod liver oil that has been found by one source to have a slight excess of PCBs.)

Oxidative breakdown products differ among the various brands. Consumer Lab (http://www.consumerlab.org/), for instance, has found that several widely available brands of fish oil contained excessive oxidative breakdown products (TOTOX). You can perform you own simple test of oxidative breakdown products: Sniff it. Your fish oil should pass the "sniff test." High quality fish oil should smell non-fishy to lightly fishy. Rancid fish oil with excessive quantities of oxidative breakdown products will smell nasty fishy.

FDA approval does not necessarily mean greater potency, purity, or effectiveness. It just means that somebody assembled the hundreds of millions of dollars to obtain FDA approval, followed by lots of marketing savvy to squash the competition.

This means that there are a number of excellent fish oil products available. My favorites are the liquid fish oils from Pharmax, Nordic Naturals, and Barleans. Capsules from Carlson, PharmaNutrients, and Fisol have also performed consistently. The "big box" capsules from Sam's Club and Costco have also performed well and are wonderfully affordable.

Wheat-free pie crust

9. December 2010 William Davis (17)

I've been working on wheat-free yet healthy recipes these past two months.

You can buy wheat-free, gluten-free foods at the store, of course. But the majority of these products are unhealthy because cornstarch, rice starch, potato starch, or tapioca starch are commonly used in place of wheat. Recall that these are among the few foods that increase blood glucose higher than even wheat.

Here's a simple recipe for wheat-free pie crust that works best for cheesecake, pumpkin pie, and cream pies, but not for berry or other fruit pies like apple.

You will need:
?
1½ cups ground pecans
6 tablespoons melted butter?or melted coconut oil
1 teaspoon vanilla extract?
2 teaspoons cinnamon
1 medium egg
2 tablespoons Truvia™ or ½ teaspoon stevia extract or ½ cup Splenda®

Mix all ingredients thoroughly in bowl. Pour mixture into pie pan and press onto bottom and sides.

Fill pie crust with desired filling. You can fill it with your favorite cheesecake recipe (e.g., Neufchatel or cream cheese, sour cream, eggs, vanilla, and stevia; add pumpkin for pumpkin cheesecake) and bake, usually at 350 degrees F for one hour.

Yes, the butter provokes insulin and artificial sweeteners can trigger appetite. But, for the holidays, a slice or two of pie made with this crust will not increase blood sugar nor trigger the uncontrolled impulse eating that wheat crust will trigger.

Have a cookie

Here's a great insight dating all the way back to 1966 from one of the early explorations in lipoproteins from the National Institutes of Health lab of Levy, Lees, and Fredrickson:

The nature of pre-beta (very low density) lipoproteins

The subject is a 19 year old female (among the total of 11 in the this small, diet-controlled study) who was first fed a low-carbohydrate (50 grams per day), low-cholesterol diet; followed by a high-carbohydrate (500 grams per day), low-fat (5 grams per day) diet.

To B or not to B

5. December 2010 William Davis (11)

Apoprotein B (apo B) is the principle protein that resides in LDL particles along with other proteins, phospholipids, triglycerides, and, of course, cholesterol.

There's a curious thing about apo B. Just like one child per family in China or one television per household in 1950s America, there is only one apo B for every LDL particle.

So measuring apo B, in effect, provides a virtual count of LDL particles. (Actually, VLDL particles, the first lipoprotein to emerge from the liver, also have one apo B per particle but LDL particles far outnumber VLDL particles.) While apo B structure can show limited structural variation from individual to individual, the effect on measured apo B is negligible.

One apo B per LDL particle . . . no more, no less. What about the other components of LDL particles?

The other components of LDL particles are a different story. Cholesterol and triglycerides in LDL particles vary substantially. Diet has profound effects on cholesterol and triglyceride content of LDL particles. A diet rich in carbohydrates, for instance, increases triglycerides in LDL particles while reducing cholesterol. This means that measuring cholesterol in the LDL fraction will be misleading, since cholesterol will be falsely low. LDL cholesterol is therefore a flawed means to assess the behavior and composition of LDL particles. In particular, when LDL particles become enriched in triglycerides, they go through a process that transforms them into small LDL particles, the variety most likely to cause atherosclerosis.

In other words, when the worst situation of all--an abnormal abundance of small LDL particles develops--it is usually not signalled by high LDL cholesterol.

Because apo B is not sensitive to the composition of LDL particles--high cholesterol, low cholesterol, high triglycerides, etc.--it is a superior method to characterize LDL particles. While apo B doesn't tell you whether LDL particles are big, small, or in between, it provides a count of particles that is far more helpful than measuring this deeply flawed thing called "LDL cholesterol."

(Even better: Count LDL particles and measure LDL size, since size gives us insight into sensitivity to oxidation, glycation, adhesiveness, ability to trigger inflammatory pathways via monocyte chemoattractant protein, various interleukins, tunor necrosis factor and others. This is why cholesterol panels should go the way of tie dye shirts and 8-track tapes: They are hopelessly, miserably, and irretrievably inaccurate. Cholesterol panels should be replaced by either apoprotein B or lipoprotein measures.)

Put lipstick on a dwarf

2. December 2010 William Davis (24)

Today, virtually all wheat products are produced from the Triticum aestivum dwarf mutant.

You might call it "multi-grain bread,""oat bread," or "flaxseed bread." You could call it "organic," "pesticide-free," "non-GMO," or "no preservatives." It might be shaped into a ciabatta, bruschetta, focaccia, or panini. It might be sourdough, unleavened, or sprouted. It could be brown, black, Pumpernickel, or white. It could be shaped into a roll, bun, bagel, pizza, loaf, pretzel, cracker, pancake, brioche, baguette, or pita. It could be matzah, challah, naan, or Communion wafers.

No matter what you call it, it's all the same. It's all from the dwarf mutant Triticum aestivum plant, the 18-inch tall product of hybridizations, backcrossings, and introgressions that emerged from genetics research during the 1960s and 70s.

According to Dr. Allan Fritz, Professor of Wheat Breeding at Kansas State University, and Dr. Gary Vocke at the USDA, over 99% of all wheat grown today is the dwarf variant of Triticum aestivum. (For you genetics types, Triticum aestivum is the hexaploid, i.e., 3 combined genomes, product of extensive hybridizations, while ancestral einkorn is a diploid, i.e., a single genome, grass. Hexaploid Triticum aestivum contains the especially hazardous "D" genome, the set of genes most commonly the recipient of genetic manipulations to modify the characteristics of flour, such as gluten content. Einkorn contains only the original "A" genome.)

No matter what you call it, add to it, how you shape it, etc., it's all the same. It's all the dwarf mutant product of tens of thousands of hybridizations.

You can put lipstick on a pig, but it's still a pig. By the way, lipstick may contain wheat.

What the Institute of Medicine SHOULD have said

1. December 2010 William Davis (47)

The news is full of comments, along with many attention-grabbing headlines, about the announcement from the Institute of Medicine that the new Recommended Daily Allowance (RDA) for vitamin D should be 600 units per day for adults.

What surprised me was the certainty with which some of the more outspoken committee members expressed with their view that 1) the desirable serum 25-hydroxy vitamin D level was only 20 ng/ml, and 2) that most Americans already obtain a sufficient quantity of vitamin D.

Here's what I believe the Institute of Medicine SHOULD have said:

Multiple lines of evidence suggest that there is a plausible biological basis for vitamin D's effects on cancer, inflammatory responses, bone health, and metabolic responses including insulin responsiveness and blood glucose. However, the full extent and magnitude of these responses has not yet been fully characterized.

Given the substantial observations reported in several large epidemiologic studies that show an inverse correlation between 25-hydroxy vitamin D levels and mortality, there is without question an association between vitamin D and mortality from cancer, cardiovascular disease, and all cause mortality. However, it has not been established that there are cause-effect relationships, as this cannot be established by epidemiologic study.

While the adverse health effects of 25-hydroxy vitamin D levels of less than 30 ng/ml have been established, the evidence supporting achieving higher 25-hydroxy vitamin D levels remains insufficient, limited to epidemiologic observations on cancer incidence. However, should 25-hydroxy vitamin D levels of greater than 30 ng/ml be shown to be desirable for ideal health, then vitamin D deficiency has potential to be the most widespread deficiency of the modern age.

Given the potential for vitamin D's impact on multiple facets of health, as suggested by preliminary epidemiologic and basic science data, we suggest that future research efforts be focused on establishing 1) the ideal level of 25-hydroxy vitamin D levels to achieve cancer-preventing, bone health-preserving or reversing, and cardiovascular health preventive benefits, 2) the racial and genetic (vitamin D receptor, VDR) variants that may account for varying effects in different populations, 3) whether vitamin D restoration has potential to exert not just health-preserving effects, but also treatment effects, specifically as adjunct to conventional cancer and osteoporosis therapies, and 4) how such vitamin D restoration is best achieved.

Until the above crucial issues are clarified, we advise Americans that vitamin D is a necessary and important nutrient for multiple facets of health but, given current evidence, are unable to specify a level of vitamin D intake that is likely to be safe, effective, and fully beneficial for all Americans.

Instead of a careful, science-minded conclusion that meets the painfully conservative demands of crafting broad public policy, the committee instead chose to dogmatically pull the discussion back to the 1990s, ignoring the flood of compelling evidence that suggests that vitamin D is among the most important public health issues of the age.

Believe it or not, this new, though anemic, RDA represents progress: It's a (small) step farther down the road towards broader recognition and acceptance that higher intakes (or skin exposures) to achieve higher vitamin D levels are good for health.

My view: Vitamin D remains among the most substantial, life-changing health issues of our age. Having restored 25-hydroxy vitamin D levels in over 1000 people, I have no doubt whatsoever that vitamin D achieves substantial benefits in health with virtually no downside, provided 25-hydroxy vitamin D levels are monitored.

Coronary calcium: Cause or effect?

28. November 2010 William Davis (25)

Here's an interesting observation made by a British research group.

We all know that coronary calcium, as measured by CT heart scans, are a surrogate measure of atherosclerotic plaque "burden," i.e., an indirect yardstick for coronary plaque. The greater the quantity of coronary calcium, the higher the heart scan "score," the greater the risk for heart attack and other unstable coronary syndromes that lead to stents, bypass, etc.

But can calcium also cause plaque to form or trigger processes that lead to plaque formation and/or instability?

Nadra et al show, in an in vitro preparation, that calcium phosphate crystals are actively incorporated into inflammatory macrophages, which then trigger a constellation of inflammatory cytokine release (tumor necrosis factor-alpha, interleukins), fundamental processes underlying atherosclerotic plaque formation and inflammation.

Here's the abstract of the study:
Proinflammatory Activation of Macrophages by Basic Calcium Phosphate Crystals via Protein Kinase C and MAP Kinase Pathways:

A Vicious Cycle of Inflammation and Arterial Calcification?

Basic calcium phosphate (BCP) crystal deposition underlies thedevelopment of arterial calcification. Inflammatory macrophagescolocalize with BCP deposits in developing atherosclerotic lesionsand in vitro can promote calcification through the release of TNF alpha. Here we have investigated whether BCP crystals can elicit a proinflammatory response from monocyte-macrophages.BCP microcrystals were internalized into vacuoles of human monocyte-derived macrophages in vitro. This was associated with secretion of proinflammatory cytokines (TNF, IL-1ß and IL-8) capable of activating cultured endothelial cells and promoting capture of flowing leukocytes under shear flow. Critical roles for PKC, ERK1/2, JNK, but not p38 intracellular signaling pathways were identified in the secretion of TNF alpha, with activation of ERK1/2 but not JNK being dependent on upstream activation of PKC. Using confocal microscopy and adenoviral transfection approaches, we determined a specific role for the PKC-alpha isozyme.

The response of macrophages to BCP crystals suggests that pathological calcification is not merely a passive consequence of chronic inflammatory disease but may lead to a positive feed-back loop of calcification and inflammation driving disease progression.

This observation adds support to the notion that increasing coronary calcium scores, i.e., increasing accumulation of calcium within plaque, suggests active plaque. As I say in Track Your Plaque, "growing plaque is active plaque." Active plaque means plaque that is actively growing, inflamed and infiltrated by inflammatory cells like macrophages, eroding its structural components, and prone to "rupture," i.e., cause heart attack. Someone whose first heart scan score is, say, 100, followed by another heart scan score two years later of 200 is exposed to sharply increasing risk for cardiovascular events which may, in part, be due to the plaque-stimulating effects of calcium.

Conversely, reducing coronary calcium scores removes a component of plaque that would otherwise fuel its growth. So, people like our Freddie, who reduced his heart scan score by 75%, can be expected to enjoy a dramatic reduction of risk for cardiovascular events.

Less calcium, less plaque to rupture, less risk.

Wheat one-liners

26. November 2010 William Davis (22)

If you're having difficulty convincing a loved one or someone else that wheat should be eliminated from the human diet, here are some useful one-liners to use:

Wheat makes your boobs big.
(This is true. Priceless for women to use on their husbands.)

Wheat causes dementia.
(And confirmed on examination of brain tissue at autopsy. Yes, autopsy.)

Wheat makes you look pregnant.
(The visceral fat of a wheat belly does a darn good imitation of a near-term infant.)

The first sign of wheat intolerance can be wetting your pants.
(Cerebellar ataxia, i.e., destruction and atrophy of the cerebellum, caused by wheat leads to loss of coordination and bladder control. Average age of onset: 53 years old.)

White flour bad, whole grain better; just as Marlboros are bad, Salems are better.
(The flawed syllogism that led to the "eat more healthy whole grain" colossal blunder.)

Wheat is the only food with its very own mortality rate.
(Celiac disease, osteoporotic hip fractures, and the neurologic diseases triggered by wheat can be fatal.)

"Wheat" is no longer wheat; it's the dwarf mutant that came from genetics research in the 1960s.
(Over 99% of all wheat today comes from the 18-inch tall dwarf mutant.)

Wheat increases blood sugar higher than nearly all other foods.
(Higher than Milky Way bars, higher than Snickers bars, higher than table sugar.)

There you have it: A full arsenal of one-liners to shoot at your husband, wife, or friend when they roll their eyes at your refusal to consume this thing called "wheat."

The happy homeotherm

24. November 2010 William Davis (14)

If you were a "cold blooded" poikilotherm unable to regulate internal body temperature, you would have to sun yourself on rocks to raise your body temperature, just like turtles and snakes. When it got cold, your metabolic rate would slow and you might burrow into the mud to hide.

You and I, however, are homeotherms, terrestrial animals able to regulate our own internal body temperature. Principal responsibility for keeping your body temperature regulated falls with the thyroid gland, your very own thermoregulatory "thermostat."

But internal body temperature, even in a homeotherm, varies with circadian rhythm: Highest temperature occurs in the early evening around 8 p.m.; the low temperature nadir occurs at around 4 a.m.

The notion that normal human temperature is 98.6 degrees Fahrenheit is a widely-held fiction, a legacy of the extraordinary experience of 19th century German physician, Carl Reinhold August Wunderlich, who claims to have measured temperatures of one million people using his crude, uncalibrated thermometer to obtain axillary (armpit) body temperatures.

Dr. Broda Barnes was a 20th century American proponent of using the nadir body temperature to gauge thyroid function. Like Wunderlich, Barnes also used axillary temperatures.

Modern temperature assessments have employed radiotransmitting thermistors that are swallowed, with temperatures tracked as the thermistor travels through the stomach, duodenum, small intestine, large intestine, rectum, then peek-a-boos back out. Such internal "core temperature" assessments have shown that:

--Axillary temperatures do not track with internal core temperatures very well, often veering off course due to external factors.
--Axillary temperatures are subject to ambient temperatures, such as room temperature, and are affected by clothing.
--Axillary temperatures are more susceptible to physical activity, e.g., increased with exercise or physical work.

Even right vs. left axillary temperatures have been shown to vary up to 2 degrees Fahrenheit.

Studies such as this demonstrate that normal oral temperature upon arising is around 97.2-97.3 degrees Fahrenheit. While we lack data correlating thyroid function with circadian temperature variation, the a.m. nadir does indeed, as Dr. Barnes originally suggested, seem to track thyroid status quite well: lower with hypothyroidism, higher with normal or hyperthyroidism.

I have been using 97.3 degrees F orally as the cutoff for confirming or uncovering thyroid dysfunction, particularly when symptoms or blood tests (TSH, free T3, free T4) are equivocal, a value that has held up well in the majority of cases. I find it helpful when, for instance, someone complains of cold hands and feet and has normal TSH (1.5 mIU/L or less in my view) but low free T3. An a.m. oral temperature of, say, 95.7 degrees F, suggests that there will be a favorable response to T3 supplementation. And it nearly always plays out that way.

Wouldn't it be interesting to know if there was insight into thyroid status provided by also examining the circadian behavior of temperature (e.g., height or timing of the peak)?

Statin buster?

19. November 2010 William Davis (20)

Merck recently reported preliminary results with its drug-in-development, anacetrapib.

After six months of treatment, participants showed:

LDL cholesterol was reduced from 81 mg/dl to 45 mg/dl in those taking anacetrapib, and from 82 mg/dl to 77 mg/dl in the placebo group.

HDL increased from 41 mg/dl to 101 mg/dl in the drug group, from 40 mg/dl to 46 mg/dl in those on placebo.

As you'd expect, the usual line-up of my colleagues gushed over the prospects of the drug, salivating over new speaking opportunities, handsomely-paid clinical "research" trials, and plenty of nice trips to exotic locales.

Anacetrapib is a cholesteryl-ester transfer protein inhibitor, or CETP inhibitor, much like its scrapped predecessor, torcetrapib . . . you know, the one that went down in flames in 2006 after 60% excess mortality occurred in people taking the drug compared to placebo. The hopes of many investors and Pfizer executives were dashed with torcetrapib's demise. The data on torcetrapib's lipid effects were as impressive as Merck's anacetrapib.

These drugs block the effects of the CETP enzyme, an enzyme with complex effects. Among CETP's effects: mediating the "heteroexchange" of triglycerides from triglyceride-rich VLDL particles that first emerge from the liver for cholesterol from LDL particles. This CETP-mediated process enriches LDL particles with triglycerides, which then make LDL a target for action by another enzyme, hepatic lipase, that removes triglycerides. This yields a several nanometer smaller LDL particle, now the number one most common cause of heart disease in the U.S., thanks to conventional advice to cut fat intake and increase consumption of "healthy whole grains."

With effects like this, anacetrapib, should it hold up under the scrutiny of FDA-required trials and not show the same mortality-increasing effects of torcetrapib, will be a huge blockbuster for Merck if release goes as scheduled in 2015. It will likely match or exceed sales of any statin drug. Statin drugs have achieved $27 billion annual sales, some of it deserved. Anacetrapib will likely handily match or exceed Lipitor's $12 billion annual revenue.

More than increasing HDL, CETP inhibition is really a strategy to reduce small LDL particles.

As with many drugs, there are natural means to achieve similar effects with none of the side-effects. In this case, similar effects to CETP inhibition, though with no risk of heightened mortality, is . . . elimination of wheat, in addition to an overall limitation of carbohydrate consumption. Not just low-carb, mind you, but wheat elimination on the background of low-carb. For instance, eliminate wheat products and limit daily carbohydrate intake to 50-100 grams per day, depending on your individual carbohydrate sensitivity, and small LDL drops 50-75%. HDL, too, will increase over time, not as vigorously as with a CETP inhibitor, but a healthy 20-30% increase, more with restoration of vitamin D.

Eliminating wheat and adjusting diet to ratchet down carbs is, of course, cheap, non-prescription, and can be self-administerd, criteria that leave the medical world indifferent. But it's a form of "CETP inhibition" that you can employ today with none of the worries of a new drug, especially one that might share effects with an agent with a dangerous track record.

Wheat-free and weight loss

13. October 2007 William Davis (14)

With a heart scan score of 1222, Leslie could be in deep trouble in short order.

At 64 years old, Leslie had gained nearly 40 lbs since she'd given up a lot of her activities caring for a husband who'd developed psychological difficulties and stopped contributing to the household duties. A tall woman at 5 ft 9 inches, she held her 202 lbs well, but her lipoprotein patterns were a disaster:

--LDL particle number 2482 nmol/l--an equivalent LDL cholesterol of 248 mg/dl (drop the last digit)
--HDL 38 mg/dl
--Triglycerides 241 mg/dl
--90% of LDL particles were small
--Lipoprotein(a) 240 nmol/l

Blood sugar was in the pre-diabetic range at 112 mg/dl, C-reactive protein was high at 3.0 mg/l, blood pressure was somewhat high at 140/84.

Now, with the exception of lipoprotein(a), these patterns are exquisitely weight-sensitive. A reduction in weight would yield effects superior to any medication I could give her.

Processed wheat products were a big problem for Leslie: whole wheat bread, pretzels for snacks, whole wheat pasta. Yes, they sound healthy, even endorsed by the American Heart Association, often bearing "heart healthy" labels on the packages. Don't you believe it.

In particular, Leslie had the number one cause for heart disease in America: small LDL particles, a pattern that is magnified 30-70% by wheat products. Endorsed by the Heart Association? (As I often tell people, if you want heart disease, follow the diet advocated by the American Heart Association.)

Leslie was skeptical, worried that she would be hungry all the time and would have virtually nothing left to eat. Instead, when she returned to the office three months later, she reported that eating was easy, finding healthy foods not containing wheat was easier than she thought, she felt great, finding more energy than she'd had in years.

She'd also shed 30 lbs.

Leslie's lipoprotein patterns also reflected the weight loss. She achieved her 60:60:60 Track Your Plaque lipid targets, small LDL shrunk dramatically, blood sugar and blood pressure were back in normal ranges.

I see results like Leslie's several times every week. For those of us with patterns like Leslie's, or just obesity that accumulates in the abdomen, going wheat-free is among the most powerful single strategies I know of.

If you need convincing, try an experiment. Eliminate--not reduce, but eliminate wheat products from your diet, whether or not the fancy label on the package says it's healthy, high in fiber, a "healthy low-fat snack", etc. This means no bread, pasta, crackers, cookies, breads, chips, pancakes, waffles, breading on chicken, rolls, bagels, cakes, breakfast cereal. I find elimination of wheat easier than just cutting back. I believe this is because wheat is powerfully addictive. It's very similar to telling an alcoholic that a drink now and then is okay--it just doesn't work. They need to be alcohol-free. Most of us need to be wheat-free, not just cut back.

You won't be hungry if you replace the lost calories with plenty of raw almonds, walnuts, pecans, sunflower and pumpkin seeds; more liberal use of healthy olive oil, canola oil and flaxseed oil; adding ground flaxseed and oat bran to yogurt, cottage cheese, etc.; and more lean proteins like lean beef, chicken, turkey, fish, and eggs.

The majority of people who go wheat-free lose weight, sometimes dramatically. Most people also feel better: more energy, more alert, better sleep, less mood swings. Time and again, people who try this will tell me that the daytime grogginess they've suffered and lived with for years, and would treat with loads of caffeine, is suddenly gone. They cruise through their day with extra energy.

Even without weight loss, going wheat-free usually raises HDL, reduces the dreaded small LDL dramtically. It also reduces triglycerides, blood sugar, C-reactive protein, blood pressure. Blood sugar control in diabetics is far easier, with less fluctuations and sharp rises in blood sugar.

Success at this also yields great advantage for your heart scan score control and reversal efforts.

Collective wisdom

12. October 2007 William Davis (5)

As public consciousness and knowledge about health issues grows, thanks to the internet and other media, I predict that:

1) Hospitals will recede into a role of acute and catastrophic care ONLY, dropping the charade of providing health, which they do NOT.

2) Doctors and other health professionals will begin to see themselves as providers of acute and catastrophic care, also. They will stop providing day to day care, such as treating high blood pressure, cholesterol, breast exams, and other preventive maintenance.

3) Instead, preventive care will be self-provided. The public will have acquired sufficient savvy and know-how to manage issues like blood pressure themselves. They will need the assistance of helpful information resources, web-based for the most part. Much preventive care can, in fact, be algorithm-driven, just like following a simple recipe.

All the worries about runaway health care costs will be much reduced, since excessive testing driven by liability worries will disappear, repeated office visits for day-to-day issues will go away. Yes, you will need a doctor and hospital for a broken leg, car accident, unexpected cancer, or non-compliance or neglect of prevention.

But osteoporosis, high blood pressure, nutrition, weight loss, hormone management, cholesterol issues, minor complaints will all be managed by people themselves with the assistance of web-based knowledge systems.

I already sense this sort of phenomeonon developing, though in its infancy, in venues like the Track Your Plaque Forum and other health portals, places where the information being discussed exceeds the quality of information you can obtain from your doctor. Over and over again, for instance, the sophistication and knowledge demonstrated by our Track Your Plaque Forum discussions shows that the public is capable of far more understanding of health issues than many previously believed. Most of our members could carry on a credible conversation with trained lipid experts. The knowledge base of our members exceeds that of 98% of most of my colleagues when it comes to heart scans, lipoproteins, and nutrition.

I am in awe of Wikipedia, the popular online encyclopedia. Five 20- and 30-somethings have created a knowledge base that has now eclipsed Encyclopedia Britannica in size and scope, with equivalent accuracy, and relatively little cost. I'd like to see the same phenomenon occur in health care information, helping to usurp the current paternalistic "I'll tell you what to do" model.

Success--Slow but sure

12. October 2007 William Davis (5)

John is a gentleman.

At age 76, he continues to teach at a local college. He's a delight to talk to, having written several scholarly books on religious topics. He's a fountain of knowledge on religious history and the roots of faith.

John is one of those incurably optimistic people, always greeting me with a smile and a warm handshake. I can't help but linger for a hour or so to talk with John, unfortunately disrupting my office schedule miserably.

John is another Track Your Plaque success story. Though he didn't set any records in reduction of his heart scan score, he did it simply by adhering to the program over a period of two years, succeeding slowly but surely.

John's first heart scan score: 1190, a score that carries as much as a 25% annual risk for heart attack. Among the list of causes was an LDL cholesterol in the 170 mg/dl range, along with an LDL particle number that verified the accuracy of LDL.

Among John's suggested treatments was a statin drug, since I was not confident he could reduce LDL with diet and nutritional modifications sufficiently to safely reduce both LDL and his risk for heart attack. But he proved terribly intolerant to any dose of any statin, with incapacitating and strange side-effects, like head-to-toe itching, abdominal cramps and diarrhea. It was clear: John needed to do the program without benefit of a statin drug.

I therefore asked John to maximize all efforts that reduce LDL, 70% of which were small LDL paricles despite his very slender build. He used oat bran and ground flaxseed daily, raw nuts, a soy protein smoothie every morning, and eliminated wheat and other high-glycemic index foods (including the Oreos he loved to snack on). Because the mis-adventures with statin drugs wasted nearly a year, I asked John to undergo another heart scan. Score 2: 1383, a 16% increase.

I asked John to keep on going. Thankfully, he did manage to tolerate fish oil, niacin (though it required over a year just to get to a 1000 mg per day dose), and vitamin D. With all these efforts, he did reduce LDL to the 80-90 mg/dl range. Of course, John's unflagging optimism was crucial. He did express his occasional anxiety over his heart scan score, but dealt with it in a logical, philosophical way. He understood that there was no role for prophylactic stents or bypass, and he accepted that much of his program rested on his ability to adhere to the strategies we advised.

Another year later, a 3rd heart scan: 1210, a 12% reduction.

I'm very proud of John and his success. When you think about it, he succeeded in conquering heart disease with some very simple tools, minus statin drugs. It can be done, but requires consistency and patience--and an optimistic outlook.

Vitamin D and octagenarians

10. October 2007 William Davis (28)

Roger practically bounced in his chair vibrating with energy.

"It must be the vitamin D! I haven't felt like this in years. I can work around the yard all day and still have energy left over."

At age 84, Roger started out with pretty good health, despite a prosthetic valve and bypass surgery 5 years earlier. He looked 74, perhaps younger.

I've seen this effect now in about 20 octagenarians. A Track Your Plaque Member mentioned this same effect in his father-in-law in a discussion in our Forum. Most are taking around 6000-8000 units per day (gelcap, of course). The average dose of vitamin D tends to be higher in this age group, since by age 80, you've essentially lost the capacity to convert 7-hydrocholesterol to active vitamin D3 in the skin. Most octagenarians start with 25-OH-vitamin D3 levels of 10 ng/ml or less--profound deficiency.

I believe the effect is real, having now witnessed it multiple times. Unfortunately, my observations are too informal to qualify as a study. (I wouldn't even know how to quantify this. I suppose some sort of muscle and coordination testing might yield quantifiable measures.) However, there are some data emerging that show less fractures, falls, improved coordination, and perhaps improved memory and mentation with vitamin D supplementation, though doses often used in studies tend to be lower than what we are using in practice.

I haven't been so excited about the effects of a nutritional supplement in a long time. Vitamin D continues to yield surprises every day in its array of positive and powerful effects.

Could we say that vitamin D restores youthfulness?

NY Times Jane Brody misses the mark

9. October 2007 William Davis (6)

NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper:

"CT Scans of the Heart Come With Trade-Offs

In her report, she says:

Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.

I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.

She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent.

This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like:

--the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.

--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors.

--There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham.

Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness.

If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.

"There must be a mistake"

9. October 2007 William Davis (2)

Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!)

You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to

http://www.cureality.com/library/fl_07-001nealt51.asp

Neal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results.

After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop."

The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment.

Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal.

I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal.

Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help."

Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them.

Should this happen to you, don't be surprised. Just bite your tongue, because you know better.

Jimmy Moore Interview: Is saturated fat the villain we thought?

7. October 2007 William Davis (45)

Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore.

On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment."

Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer.

But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts.

TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program.

I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?

JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.

While we do agree on probably 99% of the basic tenets of what I describe as
"livin' la vida low-carb," the issue of saturated fat to me is one where we
indeed do not. It's not a deal breaker regarding my support for what you do
just as I'm sure you would say the same regarding your backing of what I do. If
we all agreed on everything, then what a boring world this would be!

My thinking on saturated fat has evolved since I started eating this way nearly
four years ago. Like most people, I was terrified to eat ANY fat at all because
of the abject fear that people like Dr. Dean Ornish and other so-called health
"experts" instilled in me about how dangerously unhealthy it is to consume it.
This fat phobia is arguably the single biggest contributor to the ongoing
obesity crisis our world faces today.

With that said, you and I both know fat consumption is a part of a healthy
lifestyle. There are just too many benefits to the body that come from the
consumption of fats and even saturated fats such as coconut oil, butter, lard,
nuts, seeds, and animal fat when it is combined with a restricted carbohydrate
intake.

An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.

Here are the actual numbers from the study:

- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%
- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%
- Eating 3X the saturated fat cut the amount in the blood in half

In an interview I conducted at my blog with Dr. Volek last year (here's the
link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html),
he said the conventional wisdom regarding fat, especially saturate fat, is dead
wrong while the significance of carbs is all but ignored by those who claim to
understand the metabolic response mechanism.

Here's what Dr. Volek said in my interview:

"Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."

Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.

Here's what she said:

"Eating fat (whatever kind) does not make you fat. It does not increase blood
stream saturated fat. Eating carbs does make you fat. Eating carbs does put
saturated fat in your blood stream."

To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.

And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.

TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc.

Have you encountered any phenomena of low-fiber on your approach?

JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html).

Fiber consumption is another one of those issues that not everyone who advocates
a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet.
Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).

As for consuming the highly-touted "healthy whole grain" cereals that you
mentioned, what a travesty that would be for people trying to manage their
weight and health. While the cereal manufacturers have had a heyday in their
marketing efforts promoting their whole grain content, it's all just a big fat
ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!

Many of these "healthy" cereals contain as many carbohydrates in a single bowl
without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.

TYP: 180 lbs of weight loss in your first year is absolutely astounding.

I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently?
How are your food choices today different from that first year?

JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!

It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).

There's a balance that people need to find for themselves and it's different for
all of us. I am one of the unlucky people who has to keep his carbohydrate
intake below 50g daily or I gain. It's just a fact of life that I've come to
grips with and realize is a necessity in order to manage my weight for the rest
of my life. But I wouldn't have it any other way!

Exercise was indeed a part of my low-carb weight loss success in 2004 as I
forced myself to do cardio every single day as a commitment to this journey. In
hindsight, that was probably not the best thing for me to do since the body has
a rather peculiar way of telling you it needs to wiggle and move spontaneously
on its own rather than forcing the issue. But I consider the exercise I did to
be such an integral part of my success that I dedicated an entire chapter of my
book to the subject.

Today, my daily cardio routine is out the window and I choose instead to engage
in activities outside the gym that let me burn calories and have some fun in the
process. I regularly play volleyball, basketball, and referee flag football at
my church which all give me quite a workout. I'm very physically active and fit
on my 6'3" body and just enjoy burning off all this excess energy that I have
been given since losing nearly have my weight! I do want to get into a little
more organized resistance training routine soon to try to shape and tone some
areas of my body that still show signs of that 410-pound man I used to be
(although the loose, hanging skin in my abdomen and inner thighs isn't going to
get any better with exercise since the elasticity has been ruined from being
stretched out so far). Here is a link to some posts and pictures I have written
about this subject:
http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.html

As for my food choices today compared to my weight loss year in 2004, they
haven't really changed a whole lot. This was a lifestyle change in every sense
of the phrase and I've learned to implement this way of eating into a permanent
and healthy diet that I can and will gladly live with forever and ever amen. I
probably eat more berries, melons, and nuts today than I did then, but otherwise
it's the identical diet.

TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years.

Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins?

JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone.

Nope, I sure don't!

Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.

Anyone interested in doing the low-carb lifestyle and needs help finding which
plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html).
It's the perfect overview of low-carb living with a comparison and recap of the
major plans.

THANK YOU again for allowing me to share my story with you and your readers, Dr.
Davis!

TYP: And thanks to you, Jimmy!

Mammogram of the heart

6. October 2007 William Davis (3)

Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.

First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).

Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)

Both are also meant to be repeated periodically when normal as a surveillance process.

Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.

Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).

Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.

Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography.

CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries.

One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency.

Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.

Dr. Susie Rockway on conjugated linoleic acid (CLA)

5. October 2007 William Davis (7)

I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements.

A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives.

So I asked Dr. Rockway if she’d answer a few questions for us.

TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic?

Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!)

I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction!

Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health.

I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently.

So, how can you not be excited about this very bioactive molecule?

TYP: What are your specific areas of interest in nutrition and health?

Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health.

As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should.

Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there.

Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at.

Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research.

TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts?

Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.

When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood.

So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure.

TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years?

Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short!

We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!

One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education.

Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition.

See, it all comes back to CLA!

TYP: Thanks, Susie!

Which is better?

4. October 2007 William Davis (12)

If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:

Lipitor or a combination of fish oil, vitamin D, and elimination of wheat?

Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.

Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%.

A combination of fish oil, vitamin D, and elimination of wheat:

Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events.

On this combination, however, you also:

--Lose weight, often substantially.

--Improve bone health, esp. osteoporosis and arthritis.

--Reduce cancer risk from the vit D supplementation.

--Reduce risk of stroke.

--Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.

--Reduce winter blues.

--Experience more energy.

--Obtain increased clarity of thought (from elimination of wheat).

--Reduce blood pressure.

Oh, and there's no muscle aches.
