My life is easy

In the old days (the 1980s and 1990s), practicing cardiology was very physically and emotionally demanding. Since procedures dominated the practice and preventive strategies were limited, heart attacks were painfully common. It wasn't unusual to have to go to the hospital for a patient having a heart attack at 3 am several times a week.

Those were the old days. Nowadays, my life is easy. Heart attacks, for the most part, are a thing of the past in the group of people who follow the Track Your Plaque principles. I can't remember the last time I had a coronary emergency for someone following the program.

But I am reminded of what life used to be like for me when I occasionally have to live up to my hospital responsibilities and/or cover the practices of my colleagues. (Though I voice my views on prevention to my colleagues, the most I get is a odd look. When a colleague recently covered my practice for a weekend while I visited family out of town, he commented to me how quiet my practice was. I responded, "That's because my patients are essentially cured." "Oh, sure they are." He laughed. No registration that he had witnessed something that was genuine and different from his experience of day-to-day catastrophe among his own patients. None.)

I recently had to provide coverage for a colleague for a week while he took his family to Florida. During the 7 days, his patients experienced 4 heart attacks. That is, 4 heart attacks among patients under the care of a cardiologist.

If you want some proof of the power of prevention, watch your results and compare them to the "control" group of people around you: neighbors, colleagues, etc. Unfortunately, the word on prevention, particularly one as powerful as Track Your Plaque, is simply not as widespread as it should be. Instead, it's drowned out in the relentless flood of hospital marketing for glitzy hospital heart programs, the "ask your doctor about" ads for drugs like Plavix, which is little better than spit in preventing heart attacks (except in stented patients), and the media's fascinating with high-tech laser, transplant, robotic surgery, etc.

Prevention? That's not news. But it sure can make the slow but sure difference between life and death, having a heart attack or never having a heart attack.

My bread contains 900 mg omega-3

Phyllis is the survivor of a large heart attack (an "anterior" myocardial infarction involving the crucial front of the heart) several years ago. Excessive fatigue prompted a stress test, which showed poor blood flow in areas outside the heart attack zone. This prompted a heart catheterization, then a bypass operation one year ago.

FINALLY, Phyllis began to understand that her unhealthy lifestyle played a role in causing her heart disease. But lifestyle alone wasn't to blame. Along with being 70 lbs overweight and overindulging in unhealthy sweets every day, she also had lipoprotein(a), small LDL particles, and high triglycerides. The high triglycerides were also associated with its evil "friends," VLDL and IDL (post-prandial, or after-eating, particles).

When I met her, Phyllis' triglycerides typically ranged from 200-300 mg/dl . Fish oil was the first solution, since it is marvelously effective for reducing triglycerides, as well as VLDL and IDL. Her dose: 6000 mg of a standard 1000 mg capsule (6 capsules) to provide 1800 mg EPA + DHA, the effective omega-3 fatty acids.

But Phyllis is not terribly good at following advice. She likes to wander off and follow her own path. She noticed that the healthy bread sold at the grocery store and containing flaxseed boasted "900 mg of omega-3s per slice!". So she ate two slices of the flaxseed-containing bread per day and dropped the fish oil.

Guess what? Triglycerides promptly rebounded to 290 mg/dl, along with oodles of VLDL and IDL.

A more obvious example occurs in people with a disorder called "familial hypertriglyceridemia," or the inherited inability to clear triglycerides from the blood. These people have triglycerides of 800 mg/dl, 2000 mg/dl, or higher. Fish oil yields dramatic drops of hundreds, or even thousands of mg. Fish oil likely achieves this effect by activating the enzyme, lipoprotein lipase, that is responsible for clearing blood triglycerides. Flaxseed oil and other linolenic acid sources yield . . .nothing.

Don't get me wrong. Flaxseed is a great food. As the ground seed, it reduces LDL cholesterol, reduces blood sugar, provides fiber for colon health, and may even yield anti-cancer benefits. Flaxseed oil is a wonderful oil, rich in monounsaturates, low in saturates, and rich in linolenic acid, an oil fraction that may provides heart benefits a la Mediterranean diet.

But linolenic acid from flaxseed is not the same as EPA + DHA from fish oil. This is most graphically proven by the lack of any triglyceride-reducing effects of flaxseed preparations.

Enjoy your flaxseed oil and ground flaxseed--but don't stop your fish oil because of it. Heart disease and coronary plaque are serious business. You need serious tools to combat and control them. Fish oil is serious business for triglycerides. Flaxseed is not.

More Omnivore's Dilemma

Another irresistible quote from Michael Pollan’s book, The Omnivore’s Dilemma:

“In many ways breakfast cereal is the prototypical processed food: four cents’ worth of commodity corn (or some other equally cheap grain) transformed into four dollars’ worth of processed food. What an alchemy! Yet it is performed straightforwardly enough: by taking several of the output streams issuing from a wet mill (corn meal, corn starch, corn sweetener, as well as a handful of tinier chemical fractions) and then assembling them into an attractively novel form. Further value is added in the form of color and taste, then branding and packaging. Oh yes, and vitamins and minerals, which are added to give the product a sheen of healthfulness and to replace the nutrients that are lost whenever whole foods are processed. On the strength of this alchemy the cereals group generates higher profits for General Mills than any other division. Since the raw materials in processed foods are so abundant and cheap (ADM and Cargill will gladly sell them to all comers) protecting whatever is special about the value you add to them is imperative.”

A food manufacturer’s nightmare is when you and your family shop in the produce aisle in the grocery store. Produce is unmodified (aside from the pesticide and genetic-engineering issues), not added to, and therefore of no interest to the food manufacturer, since no additional profit can be squeezed out of it. If you pay 45 cents for a cucumber, there’s no room for a processor to multiply it’s return.

Vegetables and fruits have imperfections, no doubt, particularly pesticide residues and the “dumbing-down” of some foods to increase their desirability (e.g., green grapes, what I call “grape candy”). But vegetables and fruits are the closest you can get to foods that are essentially unmodified by a food manufacturer. Due to the absence of processing, they are not calorie-dense like a bag of chips; they include all the naturally-occurring healthy factors like flavonoids that food scientists have, thus far, struggled and failed to identify, quantify, and control; and they lack all the unhealthy additives that processed foods require for extended shelf life, palatability, and reconstitution (anti-separating agents, emulsifiers, sweeteners, etc.)

Vegetables, in particular, should be the cornerstone of your plaque control program. Not breakfast cereals, breads, bacon, sausage, mayonnaise, fruit drinks and soda, all the foods that worsen the causes of coronary plaque and raise your heart scan score.

If you would like to understand how the current perverted state of affairs in food have come about, Pollan’s book is must reading.

Pollan's The Omnivore's Dilemma


“ ‘You are what you eat’ is a truism hard to argue with, and yet it is, as a visit to a feedlot suggests, incomplete, for you are what what you eat eats, too. And what we are, or have become, is not just meat but number 2 corn and oil.”

Author Michael Pollan offers unique, enlightening, and entertaining insights into the food we eat in his new book, The Omnivore’s Dilemma: A natural history of four meals.

Pollan draws parallels between the dilemma of the primitive human living in the wild, having to stumble through the choices of animals and plants that could nourish or kill, and the ironically modern return of this phenomenon in present-day supermarkets. While the dangers of food choices aren’t as immediate as in the wild (eat the wrong mushroom or herb, for instance, and you die), they can nonetheless be life-threatening, or at least health-threatening. Hydrogenated oils, high-fructose corn syrup, carageenan, guar gum. . .“What is all this stuff anyway, and where in the world did it come from?”

Among the issues Pollan discusses is that of modern cattle raising practices: the rush to fatten a cow from an 80 lb calf to a 1200-pound, bloated cow over a period of 14 months. Nature created this animal to mature over a 4 to 5 year period through grazing, thus it’s beautifully “engineered” ruminant system that allows it to digest cellulose in grasses, a process that humans and other mammals are incapable of. The pressures to bring greater quantities of beef to market at a reduced price and make more money have resulted in a farming industry that encourages the incorporation of unnatural, often inhumane practices like corn feeding (rather than grass grazing), refeeding of bovine body parts (thus “mad cow disease”), and widespread and chronic administration of hormones and antibiotics.

(I can't help but think that the rapid and perverse fattening of cattle by industrial "farming" is paralleled by the fattening of the eating American. After all, we are the hapless recipients of this flood of cheap, unhealthy, plasticized food.)

The industrialization of food has de-personalized the act of eating. You no longer have any connection with the green pepper in your salad (unless you grew it yourself), nor do you have any appreciation for the suffering of the cow in your hamburger. Worse, the distortion of livestock raising practices has modified the food composition of meat. Range-fed animals, leaner and richer in omega-3 fatty acids, have been replaced by the marbled, saturated fat-rich modern grocery bought meats.

This is a theme that Pollan reiterates time and again: how food processing adds value to the manufacturer, often starting with a healthy ingredient but modifying it, adding ingredients, taking out others, until it’s something decidedly unhealthy. Yet the manufacturer will trumpet the fact that a healthy ingredient is included. Breakfast cereals are the most blatant example of this. What the heck are Cheerios but an over-processed attempt to make more money out of the simple oat?

Pollan’s eloquent and unique insights into food are definitely worth reading.

As always, per our Track Your Plaque policy, I recommend Mr. Pollan’s book strictly on its merits. We obtain no “cut”, commission, or other financial gain by recommending his book. Track Your Plaque members pay their modest membership fee for truth. They do not pay for us to advertise something that provides hidden advantage to us. We do not advertise, editorialize to steer you towards a specific product or service. What we say, we truly believe.

The most frequently asked question of all

The most frequently asked question on the Track Your Plaque website:

"Can you recommend a doctor in my area who can help me follow the Track Your Plaque program?"

This is a problem. Unfortunately, I wish I could tell everyone that we have hundreds or thousands of physicians nationwide who have been thoroughly educated and adhere to the principles I believe are crucial in heart disease:

1) Identify and quantify the amount of coronary atherosclerotic plaque present. In 2007, the best technique remains CT heart scans.

2) Identify all hidden causes of plaque. This includes Lp(a), post-prandial disorders, small LDL, and vitamin D deficiency.

3) Correct all patterns.


But we don't.

You'd think that this simple formula, as straightforward and rational as it sounds, would be easily followed by many if not most physicians. But Track Your Plaque followers know that it simply is not true. My colleagues, the cardiologists, are hell-bent on implanting the next new device, providing a lot more excitement to them as well as considerably more revenue.

The primary care physician is already swamped in a sea of new information, going from osteoporosis drugs, to arthritis, to gynecologic issues, to skin rashes and flu. Heart disease prevention? Oh yeah, that too. They can only dabble in heart disease prevention a la prescription for Lipitor. That's quick and easy.

Nonetheless, I believe we should work towards identifying the occasional physician who is indeed willing to help people follow a program like Track Your Plaque. As we grow, we will need to identify some mechanism of professional education and we will maintain a record of these practitioners. But right now, we're simply already stretched to the limit just doing what we are doing.

If you come across a physician who practices in this fashion and you've had a positive relationship, we'd like to hear about it.

Do stents kill?

There's apparently a lively conversation going on at the HeartHawk Blog (www.hearthawk.blogspot.com). Among the hot topics raised was just how bad it is to have a stent.

I think that my comments some time back may have started this controversy. I've lately noticed that having a stent screws up your heart scan scoring in the vicinity of the stent. I was referring to the fact that I've now seen several people in the Track Your Plaque program do everything right and then show what I call "regional reversal": unstented arteries show dramatic drops in score of 18-30%, but the artery with a stent shows significant increase in score.

This is consistent with what we observe in the world outside Track Your Plaque when stents are inserted. Someone will get a stent, for instance, in the left anterior descending artery. A year later, there will be a "new" plaque at the mouth of the stent or just beyond the far end. This is generally treated by inserting another stent. Use of a drug-coated stent seems to have no effect on this issue.

Now, my smart friends in the Track Your Plaque program would immediately ask, "Does this mean you continually end up chasing these plaques that arise as a result of stents? Do you create an endless loop of procedures?"

Thankfully, the majority of times you do not. Rarely, this does happen and can lead to need for bypass surgery to circumvent the response. But it is unusual. The tissue that grows above and below stents does seem to be unusually impervious to the preventive efforts we institute.

Perhaps there's some new supplement, medication, or other strategy that will address this curious new brand of plaque growth. Until then, you and I can only take advantage of what is known. If it's any consolation, the plaque that seems to grow because of a previously inserted stent seems to lack the plaque "rupture" capacity of "naturally-occuring" plaque. It is, indeed, somehow different. It is more benign, less likely to cause heart attack. It's always been my feeling that this tissue behaves more like the "scar" tissue that grows within stents, causing "re-stenosis", a more benign, less rupture-prone kind of tissue.

Dr. Reinhold Vieth on vitamin D

A Track Your Plaque member brough the following webcast to our attention:

Prospects for Vitamin D Nutrition
which can be found at http://tinyurl.com/f93vl

Despite the painfully dull title, the webcast is the best summary of data on the health benefits on vitamin D that I've seen. The presenter is Dr. Reinhold Vieth, who is among the handful of worldwide authorities on vitamin D. In 1999, Dr. Vieth authored the first review to concisely and persuasively argue that vitamin D nutrition was woefully neglected and that its potential for health was enormous.
(See Vieth R, Am J Clin Nutr 1999 May;69(5):842-856 at http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=10232622&query_hl=1&itool=pubmed_DocSum.)

I predict that, after viewing Dr. Vieth's hour-long discussion, you will be as convinced as I am that vitamin D is crucial for health. Unfortunately, Dr. Vieth doesn't delve into the conversation about the potential effects on heart disease, since his audience was primary interested in multiple sclerosis, a disease for which vitamin D replacement promises to have enormous possibilities. Even in 2007, the data suggesting that vitamin D has heart benefits is circumstantial. Nonetheless, from our experience, I am thoroughly convinced that, with replacement to blood levels of vitamin D to 50 ng/ml, heart scan scores drop more readily and faster.

If you view Dr. Vieth's wonderful webcast, keep in mind that when he discusses vitamin D blood levels, he's using units of nmol/l, rather than ng/ml. To convert nmol/l to ng/ml, divided by 2.5. For example, 125 nmol/l is the same as 50 ng/ml (125/2.5 = 50).

Vitamin D on Good Morning America


Positive comments about vitamin D made it to a discussion on Good Morning America today about the new and exciting developments in nutrition and "functional foods".

I'm thrilled that the media is conducting these conversations. It sure is making my job easier, not having to persuade patients that taking vitamin D is truly and hugely beneficial for health. I still have to struggle with my colleagues, who tell patients to stop the "poisonous" doses we use.

But I worry that many of the details behind vitamin D don't quite make it to the media conversation. These are crucial, make-it-or-break-it issues, such as:

--Vitamin D must be vitamin D3 or cholecalciferol, not D2 or ergocalciferol. D2 is virtually worthless. Little or none is converted to the active D3, despite the fact that D2 is the form often added to some foods.

--Vitamin D3 supplements must be oil-based capsules, or gelcaps. Tablets are so poorly or erratically absorbed that it's simply not worth the effort. (We get ours from the Vitamin Shoppe.)

--The dose should be sufficient to eliminate the phenemena of deficiency, which is around 50 ng/ml. I take 6000 units per day. Dr. John Cannell of www.vitamindcouncil.com takes 5000 units per day. I give my wife 2000 units per day (she's not as deficient as I was), each of my kids 1000 units per day, except for my 180 lb. 15 year old who takes 2000 units.

I fear that, when people hear that vitamin D packs fabulous effects for health, they will take a 400 unit tablet--nothing will happen. They will not obtain the benefits such as reduction of blood pressure and blood sugar; increased bone density, reduction of arthritis, dramatic reduction in risk for fractures; reduction in risk for colon, prostate, and breast cancer; reduction in risk for multiple sclerosis; reduction in inflammatory processes such as those evidenced by C-reactive protein; and facilitation of reduction of heart scan score.

Would you bet your life on chelation?


Hugh's heart scan score was 1751, an awful score. Recall that, at this level of scoring, Hugh's heart attack and death risk is 25% per year.

Obviously, serious efforts need to be taken. In this situation, much as I despise drug companies and what they represent and their heavy-handed ways, I'm more inclined to resort directly to prescription agents, as well as our nutritional supplements and other strategies. The price of dilly-dallying could be his death.

Hugh and his wife asked about chelation. Now, there are five studies I'm aware of that have tried to examine the value of chelation. None showed any measurable benefit, though all were rather weak in design and small in number of participants. One study, for instance, looked at whether anginal chest pains were provoked any later after chelation. Another looked at whether calf claudication, or calf cramping while walking due to artery blockages in the leg arteries, was delayed on treadmill testing after chelation. No benefit was observed: no delay in provocation of angina, no delay in provocation of claudication.

However, the adherents of chelation have been vehement enough that the NIH has funded a large, multi-center study to settle the question once and for all. Best I can tell, the study has not been contaminated by any drug company involvement. It is meant to be an unbiased, objective study of whether chelation has any value.

My personal experience in patients who underwent chelation is that, despite spending hundreds or thousands of dollars, plaque grew at the expected rate--no effect at all.

None of this constitutes proof of efficacy nor proof of lack of efficacy. We will need to await the NIH trial to have better information.

Should Hugh bet his life on chelation? I advised him strongly against it. At this point, the only reason I can see to pursue chelation would be faith--that is, expectation based not on fact, but on hope.

The powerful forces preserving the status quo


An interesting quote from the book, Critical Condition: How health care in American became big business--and bad medicine:


Politics and Profits

To protect its interests and expand its influence, the health care industrial complex has done what all successful special interests do: It's become a big donor and a high-powered lobby in Washington. In the last fifteen years, HMOs, insurers, pharmacuetical companies, hospital corporations, physicians, and other segments of the industry contributed $479 million to political campaigns--more than the energy industry ($315 million), commercial banks ($133 million), and big tobacco ($52 million). More telling is how much the health care industry spends on lobbying. It invests more than any other industry except one, according to the nonpartiisan Center for Responsive Politics. From 1997 to 2000, the most recent year for which complete data is available, the industry spent $734 million lobbying Congress and the executive branch. Only the finance, insurance, and real estate lobby exceeded that amount in the same period, with a ttoal of $823 million. In contrast, the defense industry spent $211 million--less than one-third of the health care expenditure.


These telling statistics indicate just how vigorously profit-seeking forces in heart care are trying to preserve the status quo. Hospitals want to protect their valuable procedure-driven enterprise, the pharmaceutical industry wants to protect its enormous though little-known niche of procedure-based medications (like $1200 a dose ReoPro), and the medical device industry wants to maintain the multi-billion dollar-generating machine aided and abetted by the FDA's 501k rule (that makes entry to market a breeze).

The current procedure based formula for heart disease profits so many and they are desperate to preserve it. Resistance to the deep-pocketed efforts of industry and hospitals will come from people like you and me, trying to propagate a better way.

Remember: hospital procedures for coronary disease represent the failure of prevention. They are not--any longer--successes in and of themselves.

Read a scathing insight into some of these practices by reading investigative journalists' Donald Barlett and James Steele's book, Critical Condition. I found their descriptions painfully accurate. (But don't get too angry! Remember: only optimists reverse their plaque! We need to turn the conversation in a positive direction, not just in this Blog or the Track Your Plaque website, but nationwide.)

One of the new missions for the www.cureality.com website is to help you understand just how powerful, insidious, shrewd, and pervasive the efforts to maintain the current system truly are.

Emmer, einkorn, and agribusiness

10,000 years ago, Neolithic humans did not obtain wheat products from the bagel shop, grocery store, or Krispy Kreme. They obtained wheat by locating a nearby wild-growing field of wild emmer or einkorn wheat grass, then harvesting it with their stone sickles.

Neolithic humans, such as the Natufians of the Fertile Crescent, carried their freshly-cut wheat home, then ground it by hand using homemade mortar and pestle. As yeast-raised bread was still some 5000 years in the future, emmer and einkorn wheat was not used to bake bread, but was consumed as a porridge in bowls. Einkorn has the simplest genetic code of 14 chromosomes, while emmer has 28 chromosomes.

A third variety of wheat appeared on the scene around 9000 years ago, a natural hybridization between emmer and goat grass, yielding the 42-chromosome Triticum aestivum species. Egyptians learned how to cause wheat to rise around 3000 BC, yielding bread, rather than the unleavened flatbreads of their predecessors.

From the original three basic varieties of wheat available to Neolithic man, over the past 30 years wheat has exploded to over 25,000 varieties. Where did the other 24,997+ strains come from?

In the 1980s, thousands of new wheat strains arose from hybridization experiments, many of them conducted in Mexico. Then, in the late 1980s, genetic engineering quietly got underway in which geneticists inserted or deleted single genes, mostly designed to generate specific characteristics, such as height, yield per acre, drought resistance, but especially resistance to various pesticides and weed killers. The fruits of these efforts were introduced into the market in 1994. Most of the genetically modified foods were thought to be only minor modifications of the unmodified original and thus no safety testing in animals or humans was conducted.

We now have many thousands of wheat strains that are different in important ways from original emmer, einkorn, and Triticum aestivum wheat. Interestingly, it has been suggested that einkorn wheat fails to provoke the same immune response characteristic of celiac disease provoked by modern wheat gluten, suggesting a different amino acid structure in gluten proteins. Another difference: Emmer wheat is up to 40% protein, compared to around 12% protein for modern wheat.

In other words, the wheat of earlier agricultural humans, including the wheat of Biblical times, is NOT the wheat of 2010. Modern wheat is quite a different thing with differing numbers of chromosomes, different genes due to human manipulation, varying gluten protein composition, perhaps other differences.

Somewhere in the shuffle and genetic sleight-of-hand that has occurred over the last 30 years, wheat changed. What might have been the "staff of life" has now become the cause of an incredible array of diseases of "wheat" intolerance.

Near-death experience with nattokinase

This is a true story that I personally witnessed.

A 60-some year old man heard that nattokinase "thinned the blood." So he had been taking it for the past 6 months.

One week before he came to see me, he abruptly became quite breathless. He was unable to walk more than 20 feet or bend over to tie his shoes due to the breathlessness.

He came to see me in the office. I was alarmed by how breathless he was without signs of heart failure or other obvious explanation. I sent him for an immediate CT pulmonary angiogram. Within 30 minutes, we had the diagnosis: a large "saddle" pulmonary embolus, meaning a large blood clot that straddled the right and left main pulmonary arteries. One wrong move and . . . bang! He would have been dead within a couple of minutes, since a large clot can completely occlude the large arteries feeding the lung, essentially corking any blood circuiting through the lungs and back to the left side of the heart. (Causing, incidentally, electromechanical dissociation, in which the heart keeps beating for a few minutes but no blood is being pumped. CPR can keep you alive for a few minutes, then it's over.)

When I advised the patient of the diagnosis (after initiating the REAL anticoagulants), he said, "But I was taking nattokinase!"

Exactly. Blood clots are no laughing matter. They are potentially fatal events. Betting your life on some company's advertisement is nothing short of foolish.

Anyone who reads The Heart Scan Blog knows that I am an avid supporter of nutritional supplements. I even write articles and consult for the supplement industry. But I truly despise hearing unfounded marketing claims that some supplement companies will make in the pursuit of a fast buck.

There is no doubt that we need better, safer methods to deal with dangerous blood clots, whether in the lung, pelvis, or other areas. But, before anyone takes a leap based on the extravagant marketing claims made by a supplement manufacturer, you want to be damn sure there are real data--not marketing claims, REAL data--before you use something like nattokinase in place of a proven therapy.

Don't confuse the very interesting, though unpalatable, natto with nattokinase. Natto contains vitamin K2 and some other interesting compounds, including nattokinase.

Blame the gluten?

Wheat is among the most destructive components of the human diet, a food that is responsible for inflammatory disease, diabetes, heart disease, several forms of intestinal diseases, schizophrenia, bipolar illness, ADHD, behavioral outbursts in autistic children . . . just to name a few.

But why?

Wheat is mostly carbohydrate. That explains its capacity to cause blood sugar to increase after eating, say, a turkey sandwich on whole wheat bread. The rapid release of sugars likely underlies its capacity to create visceral fat, what I call "wheat belly."

But neither the carbohydrate nor the other components, like bran and B vitamins, can explain all the other adverse health phenomena of wheat. So what is it in wheat that, for instance, worsens auditory hallucinations in paranoid schizophrenics? Is it the gluten?

First of all, what is gluten?

Gluten protein is the focus of most wheat research conducted by food manufacturers and food scientists, since it is the component of wheat that confers the unique properties of dough, allowing a pizza maker to roll and toss pizza crust in the air and mold it into shape. The distinctive “doughy” quality of the simple mix of wheat flour and water, unlike cornstarch or rice starch, for instance, properties that food scientists call “viscoelasticity” and “cohesiveness,” are due to the gluten. Wheat is mostly carbohydrate, but the 10-15% protein content is approximately 80% gluten. Wheat without gluten would lose its unique qualities that make it desirable to bakers and pizza makers. Gluten is also the component of wheat most confidently linked to immune diseases like celiac.

The structure of gluten proteins has proven frustratingly elusive to characterize, as it changes over time and varies from strain to strain. But an understanding of gluten structure may be part, perhaps most, of the answer to the question of why wheat provokes negative effects in humans.

The term “gluten” encompasses two primary families of proteins, the gliadins and the glutenens. The gliadins, one of the protein groups that trigger the immune response in celiac disease, has three subtypes: a/ß-gliadins, ?-gliadins, and ?-gliadins. The glutenins are repeating structures, or polymers, of more basic protein structures.

Beyond gluten, the other 20% or so of non-gluten proteins in wheat include albumins, prolamins, and globulins, each of which can also vary from strain to strain. In total, there are over 1000 other proteins that serve functions from protection of the grain from pathogens, to water resistance, to reproductive functions. There are agglutinins, peroxidases, a-amylases, serpins, and acyl CoA oxidases, not to mention five forms of glycerinaldehyde-3-phosphate dehydrogenases. I shouldn’t neglect to mention the globulins, ß-purothionin, puroindolines a and b, tritin, and starch synthases.

As if this protein/enzyme smorgasbord weren’t enough, food processors have also turned to fungal enzymes, such as cellulases, glucoamylases, xylanases, and ß-xylosidases to enhance leavening and texture. Many bakers also add soy flour to enhance mixing and whiteness, which introduces yet another collection of proteins and enzymes.

In short, wheat is not just a simple gluten protein with some starch and bran. It is a complex collection of biological material that varies according to its genetic code.

While wheat is primarily carbohydrate, it is also a mix of gluten protein which can vary in structure from strain to strain, as well as a highly variable mix of non-gluten proteins. Wheat has evolved naturally to only a modest degree, but it has changed dramatically under the influence of agricultural scientists. With human intervention, wheat strains are bred and genetically manipulated to obtain desirable characteristics, such as height (ranging from 18 inches to over 4 feet tall), “clinginess” of the seeds, yield per acre, and baking or viscoelastic properties of the dough. Various chemicals are also administered to fight off potential pathogens, such as fungi, and to activate the expression of protective enzymes within the wheat itself to “inoculate” itself against invading organisms.

From the original two strains of wheat consumed by Neolithic humans in the Fertile Crescent 9000 years ago (Emmer and Einkorn), we now have over 200,000 strains of wheat virtually all of which are the product of genetic manipulations that have modified the protein structure of wheat. The extraordinary complexity of wheat proteins have therefore created a huge black box of uncertainty in pinpointing which protein causes what.

But there's an easy cure for the uncertainty: Don't eat it.

Glycemic gobbledygook

The concept of glycemic index is meant to help determine what foods raise blood sugar a lot vs. what foods raise blood sugar a little. Dr. Jennie Brand-Miller's searchable database can be found here.

I have to admit that glycemic index provided me with a sense of false assurance for some years. It screwed up my health until I came to understand the issues a lot better.

For those of you just starting out in nutritional conversations, glycemic index (GI) represents a comparison of the blood glucose area-under-the-curve (AUC) over 2 hours after consuming 50 grams of the food in question compared to the AUC of glucose or white bread. Volunteers involved in developing these values are healthy people who are generally of normal weight.

Glucose, by definition, has a GI of 100. An equal quantity of sucrose (50% glucose, 50% fructose) has a GI of 60, lower than glucose. An equal quantity of whole wheat bread has a GI of 68-77 (Yes: The GI of whole wheat is higher than sucrose). Non-carbohydrate foods, such as eggs or avocado, have no GI since they do not impact on blood glucose.

Because the GI is also sensitive to how much carbohydrate is contained, the concept of Glycemic Load (GL) was introduced:

GL = (GI x amount of carbohydrate) / 100

GL is therefore the GI that incorporates the glycemic potential of the food of interest. GI does not vary with portion size; GL varies with portion size.

Let's take whole wheat pasta, a food regarded by most people as a healthy choice. Whole wheat pasta has a GI of 55--fairly low--and a GL of 29. A serving of 180 g (approximately 6 oz cooked) provides 50 g carbohydrates.

People who advocate that low-glycemic index foods would say that this is a desirable profile and should therefore replace high-glycemic index foods.

I say WRONG. First of all, most of us are not slender 20-somethings. We will therefore not show the same response as a young, slender person (like the GI volunteers), but will show exagerrated blood sugar responses. So this much low-glyemic index whole wheat pasta will typically yield a blood sugar of 120-200 mg/dl in non-diabetic people, high enough to trigger glycation. Sure, a high-glycemic index food, such as white flour birthday cake with plenty of sugary icing, might trigger a blood sugar of 140-250 mg/dl, much worse. But that doesn't make the lower blood sugar following pasta any less bad--it's still terrible.

Another issue: GI is assessed over a 2-hour timeline. What if blood sugar remains high in a sustained way, say, over 6 hours? That's precisely what whole wheat pasta will do: Keep blood sugar high for an extended period.

So not only does a low-glycemic index food like pasta increase blood sugar in most of us extravagantly, it does so in a sustained way.

Lastly, low-glycemic index pasta still triggers small LDL particles to an extreme degree, as I discussed in the previous Heart Scan Blog post, Small LDL: Complex vs. simple carbohydrates.

Don't be false reassured by the notion of low GI or GL. In fact, I'd go so far as to say that NO glycemic index is a GOOD glycemic index (or load). The foods we want to dominate our diet are the foods that aren't even listed in the GI database.

Man walks after removing wheat

No, this isn't some National Enquirer headline like "Woman delivers alien baby."

Tom is a 26-year old man with a complex medical condition, a malformation he was born with and has had reconstructed. Aside from this, he leads a normal life: works, is married, and is, in fact, quite intelligent.

He came to me for an opinion regarding his overall health. Tom was worried that his congenital condition would impair his long-term health and longevity prospects, so he wanted to optimize all other aspects of his health.

But, when I examined Tom, he could barely get himself up on the exam table without wincing in pain. When I asked him to walk, he hobbled a few steps, again clearly in pain. When I asked him what hurt, he said "everything." He said that all his joints hurt just to move.

He told me that his several doctors over the years didn't know why he was in such pain: It wasn't rheumatoid arthritis, gout, pseudogout, or any of the other inflammatory joint diseases that might account for virtually incapacitating this 26-year old man. Even the rheumatologists were stumped. It was also unrelated to his repaired congenital condition. So Tom went on with his life, barely able to even go for a walk with his wife without pain, slowing him down to the pace of an 80-year old.

So I suggested that he eliminate all wheat products. "I don't know for a fact whether it will work, Tom. But the only way to find out is to give it a try. Why not try a 4-week period of meticulously avoiding wheat? Nothing bad will come of it."

He and his wife look perplexed, but were so desperate for a solution that they agreed to give it a try.

Tom returned 6 weeks later. He walked into the room briskly, then bounded up on the exam table. He told me that, within days, all his joint pains had completely disappeared. He could walk, stretch, do all the normal physical things with none of the pain he had suffered previously.

Tom told me, "I didn't think it could be true. I thought it was just a coincidence. So I had a sandwich about 2 weeks into it. In about 5 minutes, I got about half my pains back."

Tom now remains wheat-free and pain-free, thankfully with no discernible joint impairment.

So, yes, Tom walked freely and without pain simply by eliminating wheat from his life.

Is it an immune phenomenon? Does wheat gluten trigger some inflammatory reaction in some people? There is surely something like this underlying experiences like Tom.

Wheat contains far more than gluten. Modern wheat is a collection of hundreds of different proteins, though gluten is the most plentiful, the one that confers the "viscoelasticity" of dough. But there's plenty more to wheat than gluten or celiac disease.

AGEing gracefully

Advanced Glycation End-products, or AGEs, have the potential to change our entire conversation about diet.

AGEs come from two principal sources:

1) Endogenous--Glucose-protein interactions that arise from high blood glucose levels

2) Exogenous--From diet

The first is sensitive to glucose levels: the higher the glucose level, the greater the AGE formation. The second depends on the quantity of AGE in the food consumed.

A compelling body of evidence points towards AGEs as an agent of aging, as well as kidney dysfunction, dementia, and atherosclerosis. Some of the observations made include:

--If AGEs are infused into an experimental animal, it develops atherosclerosis, kidney disease, and other "diseases of senescence" within weeks to months.

--In endothelial cells (cells lining arteries), AGE induces expression of adhesion molecules and inflammatory signals. In fibroblasts, AGE provokes collagen production. In smooth muscle cells, AGE triggers migration and proliferation. In monocytes and macrophages, AGEs induce chemotaxis and release of inflammation mediators. In short, AGEs have been implicated in just about every step leading to atherosclerosis.

--In humans, greater quantities of AGEs are present in diabetics, pre-diabetics and people with insulin resistance. We all know that these people develop atherosclerosis, kidney disease, cataracts, and other conditions at an accelerated rate.

--Foods containing greater quantities of AGEs cause endothelial dysfunction, i.e., artery constriction via blockade of nitric oxide and other mechanisms.

Short of taking agents that block AGE activity, how can you minimize the absorption or production of AGEs? There are two general strategies:

1) Keep blood glucose low--The Whitehall study demonstrated increased cardiovascular mortality with a postprandial (actually 2-hour post- 50-gram glucose challenge) blood sugar of 83 mg/dl. Lower blood glucose, less glycation. Less carbohydrates in the diet, the lower the blood sugar, the less the glycation. Studies like Whitehall demonstrate that glycation begins with glucose values within the normal range. Thus, aging occurs even with normal glucose levels. It occurs faster with higher glucose levels.

2) Choose and prepare foods with lower AGE content. Food content of AGEs is a major determinant of blood AGE levels. Fats and meats are the primary dietary source of AGEs, particularly if cooked at high temperature (broiling, frying). While this does not mean that meats and fats need to be avoided, it can mean that limiting serving size of meats and fats, while being selective in how they are prepared, are important. This can mean cutting your meats in thinner slices or smaller pieces to permit faster cooking, eating rare when possible (not poultry, of course), avoiding cooking with sauces that contain sugar (which enhances AGE formation). Is this an argument in favor of sashimi?

Minimizing exposure to AGEs, endogenous or exogenous, has the potential to slow the aging process, or at least to lessen the likelihood of many of the phenomena of aging.

More on this to come.

Small LDL: Simple vs. complex carbohydrates

Joseph is a whip-smart corporate attorney, but one who accepts advice at his own pace. He likes to explore and consider each step of the advice I give him.

Starting (NMR) lipoprotein panel on no treatment or diet change:

LDL particle number 2620 nmol/L (which I would equate to 262 mg/dl LDL cholesterol)
Small LDL 2331 nmol/L--representing 89% of LDL particle number, a severe dominance of small LDL

I advised him to eliminate wheat, cornstarch, and sugars, while limiting other carbohydrate sources, as well. Joseph didn't like this idea very much, concerned that it would be impractical, given his busy schedule. He also did a lot of reading of the sort that suggested that replacing white flour with whole grains provided health advantages. So that's what he did: Replaced all sugar and refined flour products with whole grains, but did not restrict his intake of grains.

Next lipoprotein panel with whole grains replacing white refined flour:

LDL particle number 2451 nmol/L
Small LDL 1998 nmol/L--representing 81.5% of LDL particle number.

In other words, replacing white flour products with whole grain products reduced small LDL by 14%--a modest improvement, but hardly great.

I explained to Joseph that any grain, complex, refined, or simple--will, just like other sugars and carbohydrates, still provoke small LDL. Given the severity of his patterns, I suggested trying again, this time with full elimination of grains.

Next lipoprotein panel with elimination of whole grains:

LDL particle number 1320 nmol/L
Small LDL 646 nmol/L
--48.9% of total LDL particle number, but a much lower absolute number, a reduction of 67.6%.

This is typical of the LDL responses I see with elimination of wheat products on the background of an overall carbohydrate restriction: Big drops in precisely measured LDL as LDL particle number (i.e., an actual count of LDL particles, not LDL cholesterol) and big drops in the number of small LDL particles.

You might say that wheat elimination and limitation of carbohydrate intake can yield statin-like values . . . without the statin.

Is Cocoa Puffs no longer heart healthy?

Until recently, Cocoa Puffs enjoyed the endorsement of the American Heart Association (AHA) as a heart-healthy food.

For a price, the AHA will allow food manufacturers to affix a heart "check mark" signifying endorsement by the AHA as conforming to some basic "heart healthy" requirements.

Odd thing: The list of breakfast cereals on the check mark program has shrunk dramatically. When I last posted about this, there were around 50-some breakfast cereals, from Cocoa Puffs to Frosted Mini Wheats. Now, the list has been trimmed down to 17:

Berry Burst Cheerios-Triple Berry
Cheerios
Cheerios Crunch
Honey Nut Cheerios
Kashi Heart to Heart Honey Toasted Oat Cereal
Kashi Heart to Heart Oat Flakes & Wild Blueberry Clusters
Kashi Heart to Heart Warm Cinnamon Oat Cereal
Multi Grain Cheerios
Oatmeal Crisp Crunchy Almond
Oatmeal Crisp Hearty Raisin
Quaker Cinnamon Life
Quaker Heart Health
Quaker Life
Quaker Life Maple & Brown Sugar
Quaker Oat Bran
Quaker Oatmeal Squares - Brown Sugar
Quaker Oatmeal Squares - Cinnamon


According to sales material targeted to food manufacturers, the American Heart Association boasts that "The American Heart Association’s heart-check mark is the most recognized and trusted food icon today . . . Eighty-three percent of consumers are aware of the heart-check mark. Sixty-six percent of primary grocery shoppers say the heart-check mark has a strong/moderate influence on their choices when shopping."

So, is Cocoa Puffs no longer heart healthy?

I suspect that agencies like the AHA, the USDA, the American Diabetes Association as starting to understand that they have blundered big time by pushing low-fat, having contributed to the nationwide epidemic of obesity and diabetes, and that it is time to quietly start backpedaling.

While it's a step in the right direction, judging from the above list of breakfast cereal "survivors" of the check mark program, the criteria may have been tightened . . . but not that much.

Fractures and vitamin D

This is a bit off topic, but it's such an interesting observation that I'd like to pass it on.

Over the past several years, there have been inevitable bone fractures: People slip on ice, for instance, and fracture a wrist or elbow. Or miss a step and fracture a foot, fall off a ladder and fracture a leg.

People will come to my office and tell me that their orthopedist commented that they healed faster than usual, often faster than anyone else they've seen before. My son was told this after he shattered his hand getting slammed against the boards in hockey; his orthopedist took the screws and cast off much sooner than usual since he judged that healing had occured early. (My son was taking 8000 units vitamin D in gelcap form; I also had him take 20,000 units for several days early after his injury to be absolutely sure he had sufficient levels.)

My suspicion is that people taking vitamin D sufficient to enjoy desirable blood levels (I aim for a 25-hydroxy vitamin D level of 60-70 ng/ml) heal fractures much faster, abbreviating healing time (crudely estimated) by at least 30%.

For any interested orthopedist, it would be an easy clinical study: Enroll people with traumatic fractures, randomize to vitamin D at, say, 10,000 units per day vs. placebo, watch who heals faster gauged by, for instance, x-ray. My prediction: Vitamin D will win hands down with faster healing and perhaps more assured fusion of the fracture site.

T3 for accelerating weight loss

Supplementation of the thyroid hormone, T3, is an underappreciated means to lose weight.

Thyroid health, in general, is extremely important for weight control, since even subtle low thyroid hormone levels can result in weight gain. The first step in achieving thyroid health is to be sure you are obtaining sufficient iodine. (See Iodine deficiency is real and Healthy people are the most iodine deficient) But, after iodine replacement has been undertaken, the next step is to consider your T3 status.

I've seen T3 ignite weight loss or boost someone out of a weight loss "plateau" many times.

Endocrinologists cringe at this notion of using T3. They claim that you will develop atrial fibrillation (an abnormal heart rhythm) and osteoporosis by doing this. I have yet to see this happen.

Adding T3 revs up metabolic rate at low doses. The idea is to push free T3 hormone levels to the upper limit of normal, but not to the hyperthyroid range. While an occasional person feels a little "hyper" like they've had a pot of coffee, most people just feel energized, clear-headed, and happier. And weight trends down much more readily.

Taking T3 by itself with no effort at weight loss generally yields only a modest weight reduction. However, T3 added to other weight reducing efforts, such as wheat elimination and exercise, accelerates the weight loss effect considerably. 5 lbs lost will likely be more like 8 to 10 lbs lost; 10 lbs lost will likely be more like 15 to 20 lbs, etc.

It's also my suspicion that more and more people are developing a selective impairment of T3, making it all the more important. I believe that you and I are being exposed to something (perchlorates, bisphenol A, perflurooctanoic acid, and others?) that may be impairing the 5'-deiodinase enzyme that converts the T4 thyroid hormone to the active T3. Relative lack of T3 leads to slowed metabolism, weight gain, and depressed mood. While avoiding or removing the toxin impairing 5'-deiodinase would be ideal, until we find out how to do this, taking T3 is a second best.

The tough part: Finding a prescriber for your T3.
