What if your lipoproteins are perfect?



Sandy is a 56-year old woman--fit, slender, physically active, with no bad habits. A retired teacher, she has time to devote to her health. She bikes several days per week, mountain bikes, walks, and takes fitness classes. In short, she's the picture of perfect health.

Her heart scan score was not terribly impressive: 41. However, at her age, this modest score placed her in the 77th percentile. This suggested a heart attack risk of around 2-3% per year.

So we measured Sandy's lipoproteins. They were shockingly normal. In fact, Sandy is among the very rare person with absolutely no small LDL particles. All other patterns were just as favorable, including an HDL in the 80s.

This may seem like good news, but I find it disturbing. People are often initially upset by seeing multiple abnormal lipoprotein patterns. But lipoprotein abnormalities are the tools that we use to gain control over coronary plaque.

So what do we do when there are no abnormalities?

There are several issues to consider:

1) Your heart scan score reflects the sum total of your life up until that point. What if you were 20 lbs heavier 10 years earlier and your lipoproteins were abnormal during that period? Or you smoked until age 45 and quit? As helpful as they are, lipoproteins and related patterns are only a snapshot in time, unlike the heart scan score.

2) You have a vitamin D deficiency. This is unusual as a sole cause of coronary plaque. Much more commonly, it is a co-conspirator.

3) The heart scan is wrong--highly unlikely. Heart scans are actually quite easy, straightforward tests. (The only time this tends to happen is when scoring that appears in the circumflex coronary artery is actually in the nearby mitral valve. This really occurs only when there's very minimal calcium in the valve.)

4) There's a yet unidentified source of risk. Probably very rare but conceivable. For instance, there's an emerging sense that phopholipid patterns may prove to be coronary risks. One clinically available measure that we've not found very useful is phospholipase A2, known by the proprietary name "PLAC" test. (See http://www.plactest.com for more information from the manufacturer/distributor of the test.) But there's probably lots of others that may prove useful in future.

How often does it happen that someone fails to show any identifiable source for their coronary plaque? I can count the number of instances on two fingers--very unusual. (Thank goodness!)

Sandy's case is therefore quite unique. How should we approach her coronary plaque? In this unusual circumstance, lacking a cause, we tend to introduce therapies that may regress plaque independent of any measurable lipoprotein parameters. But that's a whole new conversation.

Fly to India for a bypass operation?


In the June 19, 2006 issue of People Magazine, there's an article called "The Doctor is in . . .INDIA". The report talks about how, with health care costs in the U.S. spiralling out of control, more and more Americans are leaving the country to have their procedure performed.

They tell the story of Mr. Carlo Gislimberti of New Mexico and cite these numbers:

Heart Surgery
Cost in U.S.: $200,000

Cost in India: $10,000


Mr. Gislimberti opted to have his coronary bypass operation in India for cost reasons.

But the People magazine report left out one other option: The Track Your Plaque program: $39.00

Do your part to save ballooning health care costs: Engage in a truly powerful program of heart disease prevention like the Track Your Plaque program. The cost difference is laughably huge. And you won't require a 12-inch chest incision.

Follow conventional guidelines and guess what? You're going to have a heart attack. Follow the American Heart Association diet and you'll have heart disease.

Cut to the chase. The only program that is able to detect, track, and control coronary plaque better than any other process I know of is this program.

Note: I am not proposing that a heart disease prevention program like Track Your Plaque can replace a procedure like coronary bypass when a dangerous situation has developed. The Track Your Plaque program is designed to be implemented in the years before heart surgery is required. That's when you have the greatest control over your fate.

Surprise: Heart scan score reversal

Gene is a jovial, fun-loving railroad worker who didn't take anything too seriously--including his heart scan score of 767.

This score placed Gene solidly in the 99th percentile (in the worst 1%). It came as no surprise to Gene. After all, his father died at age 36 of a heart attack and Gene's brother died at 60 of a heart attack. So Gene took life as it came and long ago decided not to fret about his fate.

But Gene's wife prodded him and prodded him to get the heart scan. That's when I met him.

Of course, Gene had been prescribed Lipitor by his doctor for a somewhat high LDL cholesterol. Our assessment uncovered several additional patterns including lipoprotein (a), small LDL, a pre-diabetic tendency, and a severe deficiency of vitamin D.

At 224 lb and 5 ft 6 inches in height, I felt that Gene was at least 40 lbs overweight.

One year later and with reasonable correction of all his patterns except weight loss and Gene's heart scan score was 590--a reduction of 23%!

Gene was thrilled, as was I. But, frankly, I was also surprised. Dramatic regression of coronary plaque tends to not occur so readily as long as pre-diabetic patterns persist and weight is not controlled.

The lesson: Often the only way to tell if you've achieved control or regression of coronary plaque is to have another heart scan. The tremendous variation in human responses never ceases to amaze me.

Call me when you're having chest pain


I met a patient, Anna, yesterday. She was quite frustrated and frightened.

At age 50, Anna suffered a heart attack and received a stent to her left anterior descending coronary artery. What she found upsetting is that, because several members of her family had suffered heart attacks in their 40s (Dad--heart attack at age 45, paternal uncle--heart attack age 40, and even another uncle with heart attack in his late 20s), she had repeatedly asked her doctor whether she was okay.

She received the usual array of false assurances: "You're feeling fine, right? Then don't worry about it." "Look. Your cholesterol is in the normal range. Even your cholesterol/HDL ratio is fine." "Women don't get heart disease until later in life."

All proved absolutely false. As we talked, Anna exclaimed, "I think what I've been told all along is that we'll take you seriously when you finally have a heart attack!"

She's exactly right. The vast majority of times, heart disease is discovered by accident, usually because of an "event" like heart attack. This is like changing the oil in your car when it finally breaks down--it's too late.

CT heart scan, followed by lipoprotein testing and associated values, then correction of your specific causes. It's that simple.

Self-empowerment is coming!

I've discussed this before: The coming wave of self-empowerment in health. Health that is driven by you, not a hospital, not a doctor, not by procedures, but by information and access to tools that are powerful and effective.

The seeds are being planted right now and won't take full root for many years or decades. But it's going to happen.

I previously cited several broad trends that are examples of this emerging wave:

--The nutritional supplement movement. Contrary to the media's ill-informed bashing, nutritional supplements are getting better: improved quality, better substantiation of when/how to use them, new agents that appear rapidly, since introduction is not slowed by the molasses of the FDA.

--Medications moving to over-the-counter status. Health insurers are driving this one. OTC means not paid for by insurance. That also means access to you.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The mind-boggling rapidity and depth of information available on the Internet today is fueling the self-empowerment movement by providing sophisticated information to health care consumers. Information here is uneven at present. But, as consumer sophistication increases and the system of checks and balances evolves, internet-driven information will be often superior to what you get from a doctor or other health professional.

--High-deductible health insurance plans. If health care consumers bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention and minimize long-term costs.

This trend does not mean treating your own infection, taking out your own gall bladder, repairing your own broken leg. It means that conventional routes of health delivery will recede into providing only catastrophic care.

It means that you and your family will take a larger role in learning how to eat and exercise properly, use foods to maintain and promote health (the "designer food" and "nutraceutical" movement), take supplements that have real benefits, use medications for treatment of many everyday ailments.

It also means seizing control of diseases that previously were only treated in hospitals, like coronary heart disease. This, of course, is where our program, Track Your Plaque, is an example of how you can have a powerful and effective role in your heart health. Track Your Plaque goes so far beyond the "eat low-fat, exercise, and know your numbers" media mantra that it's like comparing a brand-new Mercedes to a rusted, run-down '87 Ford Escort. There truly is no comparison. (Sorry if you're an Escort driver!) But you get the idea.

Another option for lipoprotein testing


For those of you who have been frustrated in trying to get your lipoprotein analysis performed, here's another option.

The Life Extension Foundation at www.lef.org provides access to the VAP test, or Vertical Auto Profiler. This is the lipoprotein test run by the Atherotech company in Birmingham, Alabama. The name refers to the method used, a form of centrifugation, or high-speed spinning of your blood (plasma) to separate the various components by density.

This is a fine technique that works well. Though our preferred method is NMR (www.Lipoprofile.com, Liposcience Inc.), the Atherotech VAP is a reasonable alternative.

If you go through the Life Extension process, they will direct you to blood draw sites in your area. They charge $185 for Life Extension members, $247 for non-members. (Membership in Life Extension costs $75.) Drawback: No billing for health insurance reimbursement.

A full description of the significance of lipoproteins can also be found in my article posted on-line at the www.lef.org website at http://www.lef.org/magazine/mag2006/may2006_report_heart_01.htm

Weight and lipoproteins

Tom, an accountant, came into the office eager to know what his 2nd heart scan score showed.

A year ago, Tom's view of himself as a healthy, middle-aged man was shattered when he found out his heart scan score: 1236. Tom had severe coronary plaque with a heart attack risk of 25% per year (without intensive preventive action).

In the way of lipoprotein abnormalities, he had several: low HDL, deficient large HDL, small LDL, high triglycerides, IDL (the after-eating inability to clear dietary fats), and a high blood sugar in the pre-diabetic range. In addition, Tom was hypertensive, with blood pressure so high it even landed him in the emergency room last winter.

In addition to our approach to correct all these patterns, Tom was urged to lose a significant quantity of weight. Starting at 225 lb., at 5 ft 7 inches, Tom was clearly at least 40 lbs over his ideal weight.

I stressed to Tom that the entire spectrum of causes of coronary plaque were weight-related. I likened his patterns to throwing gasoline on a fire: As weight increased, his lipoprotein and other abnormalties flared dramatically.

But each time Tom came back to the office over the ensuing year, he'd gained another 3 to 6 lbs. And each time he had an explanation. "My daughter just got married. I couldn't turn down wedding cake, now could I?" Or, I just survived another tax season. I was working day and night--no time for exercise!" "It's getting too hot to walk anymore."

Well, despite multiple treatments, Tom's repeat heart scan showed a score of 1677, a 35% increase. That's a dangerous rate of growth that virtually guarantees that plaque is building up momentum to "rupture", which results in heart attack.

I therefore stressed to Tom that weight loss was crucial. Control of coronary plaque was simply not going to occur without weight loss to our target. Alternatively, we could add several new prescription medicines and hope that they could achieve the same effect, though at a price (side-effects, expense).

I tell Tom's story to highlight again just how important weight loss can be for a number of lipoprotein abnormalities.

What measures specifically are sensitive to weight? They are:

--HDL cholesterol
--Triglycerides
--Small LDL
--VLDL
--Blood pressure
--Blood sugar and insulin
--C-reactive protein
--LDL

Weight exerts profound influence on these patterns. In Tom and people like him, weight can be a "make it or break it" issue.

If you, like Tom, have any of the above patterns, consider weight loss as a potent tool you can use to gain control of coronary plaque.

Variation in vitamin D requirements


For Track Your Plaque followers, you know we are very concerned about vitamin D blood levels. My prediction is that, in 10 years, vitamin D will be regarded as an important item on the list of coronary artery disease risk factors.

In our experience of trying to stop or reverse heart scan scores, restoration of vitamin D to a blood level of 50 ng/ml appears to have increased our success rate dramatically.

As we've talked about before, on the bell curve of vitamin D dosing in a northern climate, the majority of women require 2000 units per day, men require 3000 units per day to achieve a level of 50 ng. However, there are "outliers" on this bell curve, i.e., people who require much more or much less.

This week, I saw two people who were very instructive cases of extreme requirements on the high end of vitamin D dosing. Both started with unmeasurable blood levels, i.e., essentially zero ng/ml. On 5000 units of vitamin D per day, both raised their blood levels to around 17-18 ng/ml--in the range of severe deficiency (defined as <20 ng/ml). I advised both to increase their oral dose of vitamin D to 8000 units per day.

Notably, both people avoided sunlight and lived in Wisconsin, a terribly sun-deprived locale 10 months a year. Both were also substantially overweight (around 300 lbs each).

The vitamin D issue continues to be endlessly fascinating in all its nuances and twists.

Heart attacks in your own backyard

Two men from my community just died of heart attacks. Both were in their 40s.

What bothers me most about these all too frequent stories is that it is so preventable. You can bet that both had little or no symptoms prior to their deaths. You can also bet that they've had cholesterol panels taken by their doctors.

Followers of the Track Your Plaque program know that these are sure-fire paths to failure. The absence of heart disease symptoms should provide no reassurance whatsoever. High cholesterol, in-between cholesterol, low cholesterol--none are confident indicators in a specific individual.

Stress test? How about the patient I saw today who, until I met him, had been undergoing stress test after stress test, every year--all while the quantity of coronary plaque tripled. False reassurances provided by his cardiologist led him to believe that all was well--while this stack of oily rags was just waiting for the spark to ignite.

Too little time, too much money, too far away--there's a hundred excuses for not getting a heart scan. Or, you've had a heart scan and no one can tell you what to do about it. If you're reading this, however, you've found the most intensive source of information available on how your heart scan can serve as the start of a program of heart attack prevention for a life free of dangers.

It's not that tough. But it won't just go away on its own. I just have to look around me in my own community, watch the local news, talk to friends, and I'll heart about all the people just in my neighborhood who should be learning these lessons. I rant and rave about this but some people need to hear it from a friend, colleague, neighbor, rather than some crazy doctor bucking the standard line.

You, too, should be telling anyone who will listen about how heart disease can be identified and controlled.

Pilot lands safely after heart attack, then dies

That was the disturbing headline on a report from MSNBC, also reported nationally on all the major news networks.

The story goes on:

"A pilot suffering a heart attack made an emergency landing on a highway, saving his three passengers shortly before he died...He landed the single-engine Cessna 185 on Utah 30 near Park Valley and was taken to Bear River Hospital in Tremonton, where he died."

We track these sorts of stories and it's frightening just how common they are. A school bus driver recently had a heart attack while driving 30 children; the bus crashed but no one was hurt. A 52-year old commercial bus driver suffered a heart attack while transporting 49 conference attendees; the bus plunged 400 feet down a ravine. Remarkably, 17 passengers suffered only minor injuries and there were no deaths.

There have even been incidents where the pilot of a jet liner suffered a heart attack in-flight. In 2000, the 53-year old pilot of a Northwest Airlines DC-10 died while in-flight from a heart attack while landing in Minneapolis. The 290 passengers were landed safely by co-pilot.

Most incidents where the driver or pilot has been incapacitated or died resulted in the deaths of only a handful of people. No major catastrophe has yet occured. But--mark my words--it will. These incidents just happen too frequently.

Virtually all of these and similar incidents could have been prevented. If the FAA, for instance, would insist that all pilots have a simple CT heart scan, it would become immediately obvious which pilots should be grounded and who should fly. Similar requirements could easily be applied to persons in charge of the welfare of many people, most notably school bus drivers.

It's not that tough! The FAA currently requires stress testing and cholesterol testing. Well, guess what? Followers of the Track Your Plaque program know that these tests do not effectively identify the person at risk for heart attack in the majority of individuals. Just ask former President Bill Clinton how helpful his stress tests (five in a row!) were. Or how valuable his cholesterol monitoring was--all prior to his emergency bypass surgery.

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.
Does fish oil cause blood thinning?

Does fish oil cause blood thinning?

Omega-3 fatty acids from fish oil have the capacity to "thin the blood." In reality, omega-3s exert a mild platelet-blocking effect (platelet activation and "clumping" are part of clot formation), while also inhibiting arachidonic acid formation and thromboxane.

But can fish oil cause excessive bleeding?

This question comes up frequently in the office, particularly when my colleagues see the doses of fish oil we use for cardiovascular protection. "Why so much fish oil? That's too much blood thinning!"

The most recent addition to the conversation comes from a Philadelphia experience reported in the American Journal of Cardiology:

Comparison of bleeding complications with omega-3 fatty acids + aspirin + clopidogrel--versus--aspirin + clopidogrel in patients with cardiovascular disease.(Watson et al; Am J Cardiol 2009 Oct 15;104(8):1052-4).

All 364 subjects in the study took aspirin and Plavix (a platelet-inhibiting drug), mostly for coronary disease. Mean dose aspirin = 161 mg/day; mean dose Plavix = 75 mg/day. 182 of the subjects were also taking fish oil, mean dose 3000 mg with unspecified omega-3 content.

During nearly 3 years of observation, there was no excess of bleeding events in the group taking fish oil. (In fact, the group not taking fish oil had more bleeding events, though the difference fell short of achieving statistical significance.) Thus, 3000 mg per day of fish oil appeared to exert no observable increase in risk for bleeding. This is consistent with several other studies, including that including Coumadin (warfarin), with no increased bleeding risk when fish oil is added.

Rather than causing blood thinning, I prefer to think that omega-3 fatty acids from fish oil restore protection from abnormal clotting. Taking omega-3 fatty acids from fish oil simply restores a normal level of omega-3 fatty acids in the blood sufficient to strike a healthy balance between blood "thinning" and healthy blood clotting.

    As a veterinarian I've dispensed fish oil capsules for several years.  Some owners give so many that the dogs smell 'fishy' when seen for routine care.  The owner doesn't smell it since they're with the dog a lot.  The coats are gorgeous, something that doesn't often happen in Wyoming at 7000ft altitude.

    Due to an afib episode a couple of years ago, I was taking 20 mg of warfarin per day, plus around 5000 mg of EPA+DHA, and never had bleeding issues.  

    My INR was always a stable 2.0.

    As I've not had an afib reoccurrence, I've replaced the 20mg coumadin with 325mg aspirin daily, and still take around 5000 mg EPA+DHA.  No bleeding issues with that combo either.

    Glad this topic came up.
    Over the last 5 years, I've had to periodically eliminate my fish oil intake as I would start to bruise badly. My internist said she has seen this occasionally with fish oil and called it "capillary fragility." I bruise easily anyway, but it would really get bad with fish oil. So there must be some quality in fish oil that influences this.

    Then about 6 months ago I started a strong supplement change to help with my low bone density--already taking magnesium and calcium but added:
    Boron, K2, silica,pomegrantate juice, and BIG increase in vitamin D.
    I also increased omegas to 3,000 a day which I was not able to tolerate before.

    It has been over 4 months since I have had ANY bruise---which is just unheard of for me. I usually have 3-4 different bruises on arms/legs. So something in these supplements  strengthened my capillaries I guess, and I can now take high fish oil doses!
    Anyone else had a bruising problem with fish oil?

    Hi, Catherine--

    Fascinating observation!

    I'll bet it has something to do with the vitamin D, more than anything else. Vitamin D seems to strengthen structural tissues in bones, muscle, heart valves, and perhaps capillaries and other small blood vessels.

    Several years ago I bruised easily for a while and attributed it to taking garlic supplements daily.  I started taking Vit C and the bruising stopped.  I don't think it had to do with fish oil (in my case); I don't think I was taking fish oil at the time.

    I too achieve rapid blood thinning when taking 2400mg of EPA/DHA per day. That's only 4 pharmaceutical grade capsules. Even after my vitamin d levels were normalized I still got bruising.

    I now take Vitamin K2 (MK-7 natto extract) twice a week and it's allowed me to bump my EPA/DHA up to 3600mg with no ill effects or bruising.

    It was either supplement or eat a lot of aged cheese, they both seemed to do the trick in my particular case.

    Thank you for sharing this study with us.  It helps clarify whether there is a risk for blood thinning from taking fish oils.  This information may help individuals who are taking blood thinning medications and considering adding fish oils to their daily diet.

    Catherine,

    Without a doubt, your cessation of bruising was due to vitamin k2. I routinely take nattokinase, large doses of fish oil, curcumin, and other blood thinning agents, and if I don't take vitamin K2, I will begin bruising. (I also take high doses of Vitamin D). When I take K2, I have absolutely no bruising.

    Vitamin K2 has many clinical trials showing that it helps endothelium  integrity and elasticity.

    Also, grapeseed extract and pine bark extract (specifically oligomeric proanthcyanins) has the same beneficial effect.

  • Catherine

    10/28/2009 4:41:41 PM |

    Daniel,

    That's really interesting! There is a lot of research on K2's effect on strengthening weak bones. Bone fractures go down considerably when high doses of K2 are used (Japan is using K2 as osteoporosis treatment) BUT studies show it needs to be in conjunction with adequate calcium and Vitamin D---they work synergistically for bone strength.  So it makes sense that K2 and D could do the same with strengthening fragile capillaries. I am also taking the M7 natto form.

  • Catherine

    10/29/2009 12:01:36 AM |

    Dave,

    Thanks for sharing your experience with this, you've really confirmed it now for me.  I can't believe I have suffered with this for most of my life with no answers (tried high dose Vit C, grape seed, etc) and now within months on K2, there's no bruising and I can tolerate fish oil. Hope my bones are responding this well!
    This blog is so helpful....
