Dr. Joseph Prendergast and l-arginine

In response to a discussion started by Track Your Plaque Member, Rich, on the Member Forum, I tracked down Dr. Joseph Prendergast, who had posted a video on his unique experiences, both personal and professional, with l-arginine.

Dr. Prendergast describes some of this in a brief webcast. Here, I quote Rich:

“This 90-second video by a Palo Alto physician (internal/endocrine, diabetes specialist) will totally blow your mind.

http://enews.endocrinemetabolic.com/2007/08/16-12-years.html

You will see in the link below that he reversed his personal atherosclerotic disease, diagnosed in abdominal aorta at age 37—completely reversed. He's now much older."

http://www.endocrinemetabolic.com/about/press/larginine.pdf



I contacted Dr. Prendergast to find out more.

Dr. Joseph Predergast is founder of the Endocrine Metabolic Medical Center in Palo Alto, California, focused on providing care for people with diabetes. In addition to the website, he provides Blogs and newsletters, though most of his conversation is about diabetes issues. Dr. Predergast’s website is located at http://www.endocrinemetabolic.com.

I asked Dr. Prendergast several questions about his l-arginine experience. His brief answers are below.



1) What dose of l-arginine have you employed in your patients and why this dose?

The dose is 3 - 6 grams as suggested by the Stanford Cardiovascular Research Department Chairman John Cooke. http://med.stanford.edu/profiles/John_Cooke/

2) I gather that you have preference for specific preparations of l-arginine. Can you say why some preparations seem superior to others in your experience?

I started with pharmaceutical l-arginine from the pharmacy. I gradually began to add components that would augment the power of the l-arginine and have gone through 12–15 different products. I have completely reversed my own very severe atherosclerosis discovered at age 37 and there has been less than 0.05% cardiovascular disease in my endocrine practice in almost 17 years. Both my exams were evaluated with CT technology. I am now using ProArgi9 Plus that includes several anti-aging components and will likely never switch. http://www.synergyworldwide.com/synergycorp/home.aspx

3) Are you employing any other unique practices in your patients to reduce cardiovascular events?

Withdrawing as many prescription drugs as possible.




Interesting. Of course, I also advocate l-arginine as a facilitator of atherosclerotic plaque regression, though I am not as ebullient about its use as Dr. Prendergast.

Instead, I see l-arginine as a method that yields forced normalization of “endothelial dysfunction,” the abnormal constriction and other effects that develop when abnormal lipoproteins and unhealthy food by-products are present in the circulation. Endothelial dysfunction is an inevitable accompaniment of plaque.

However, unlike Dr. Predergast’s experience, despite our use of doses higher than he uses, I have never seen plaque regression just using l-arginine alone. Nonetheless, it’s good to hear that others are seeing at least some positive effects.

By the way, we have also had some positive posts on our Forum about the ProArgi9 product he uses.

Dr. Dwight Lundell on omega-3s and CLA



An interview with Dr. Dwight Lundell, cardiac surgeon and author of the new book, "The Cure for Heart Disease."


Dr. Lundell comes to us with a unique pedigree. He is a cardiothoracic surgeon practicing in the Phoenix, Arizona, area. Despite having performed thousands of coronary bypass operations, including numerous "off-pump" procedures earning him a place in the Beating Heart Hall of Fame and a listing in Phoenix Magazine’s Top Doctors for 10 years, more recently Dr. Lundell has turned his attentions away from traditional surgical treatment and towards prevention of heart disease and.

In particular, Dr. Lundell is a vocal advocate for omega-3 fatty acids from fish oil and conjugated linoleic acid, or CLA.

When I heard about Dr. Lundell’s unique perspectives, I asked him if he’d like to tell us a little more about his ideas. Here follows a brief interview with Dr. Lundell.



You’re a vocal advocate of the role of omega-3 fatty acids from fish oil in heart disease prevention. Can you tell us how you use it?

In my book, I recommend 3 g of fish oil daily. This would normally yield about 1000 mg of EPA and DHA depending on the concentration of the supplement. This is approximately the dose that reduced sudden cardiac death by 50%, and all cause death, by 25% in patients with previous heart attack.

In patients with signs of chronic inflammation such as heart disease, obesity, arthritis, metabolic syndrome or depression or in those patients with elevation of CRP, I would recommend higher doses, 2000 to 3000 mg per day of EPA and DHA. The FDA has approved up to 3400 mg for treating patients with severely elevated triglycerides.

I personally take a 2000 mg EPA and DHA per day because I have calcium in my coronary arteries.




Of course, in the Track Your Plaque program we track coronary calcium scores. Do you track any measures of atherosclerosis in your patients to chart progression or regression?

Carotid ultrasound with measurement of IMT [intimal-medial thickness] has been shown to be a good surrogate marker for coronary disease, as has vascular reactivity in the arm. CT scanning with calcium scoring is a direct marker of coronary disease. CT does not differentiate between stable or unstable plaque but there is no good noninvasive way of doing this.

The dramatic value of CT scan calcium scoring is to demonstrate to people that they actually do have coronary disease and to motivate them to make the necessary lifestyle and nutritional changes to reduce it. CT scan with calcium scoring is a direct way to measure the progression or regression of coronary artery disease. If there is a choice between a direct measurement and indirect measurement, always choose the direct method.

Every patient treated with CLA in my clinic, experienced significant reductions in C-reactive protein. These patients were also on a weight-loss program, so I can't prove whether it was the CLA or the weight-loss that improved their inflammatory markers. In the animal model for arteriosclerosis, CLA has a dramatic effect of reducing and preventing plaque. This has not yet been proven in humans.

Normally, when people lose weight 20% or more of the loss is lean body mass (muscle) this lowers the metabolic rate and frustrates further weight-loss. My patient, from teenagers to retirees, lost no lean body mass and continued to have satisfactory weight-loss when CLA was used as part of the plan.



In reading your book, your use of conjugated linoleic acid (CLA) as a principal ingredient struck me. Can you elaborate on why you choose to have your patients take CLA?

My enthusiasm for CLA is based on:

1) Safety?this is of paramount importance. Animal toxicity studies have been done, as well as multiple parameters measured in human studies, both of these are well reviewed recently in the American Journal of Clinical Nutrition (2004:79(suppl)1132s). CLA, a naturally-occurring substance, is not toxic or harmful to animals or humans. The only negative report is by Riserus in Circulation (2002), where he found an elevated c- reactive protein; however, he used a preparation that is not commercially available and not found in nature as a single isomer.

2) Effectiveness?also critically important. A recent meta-analysis [a reanalysis of compiled data] in the American Journal of Clinical Nutrition (2007; 85:1203-1211) demonstrated the effectiveness of CLA in causing loss of body fat in humans. The study also reconfirmed the safety of CLA.

Since we now know that atherosclerosis is an inflammatory disorder, any strategy that reduces low-grade inflammation without significant side effects would seem to be beneficial in the treatment and prevention of atherosclerosis. CLA not only has antioxidant properties, but it modulates inflammatory cascade at multiple points. CLA reduces PGE2 (in much the same way as omega-3) CLA also has been shown to reduce IL-2, tumor necrosis factor-alpha and Cox–2. It reduces platelet deposition and macrophage accumulation in plaques. It also has some beneficial effect in the PPAR [peroxisome proliferator-activated receptors, important for lipid and inflammatory-mediator metabolism] area.

Part of the effect of CLA may be because it reduces fat mass and thus the amount of pro-inflammatory cytokines produced by fat cells.

I reiterate and fully admit that CLA has not been shown to have any effect on atherosclerosis in human beings. However, the results in the standard animal models for atherosclerosis (rabbits, hamsters,APO-E knockout mice) are very dramatic.

From all I know, it appears that the effective dose for weight loss and the animal studies in atherosclerosis would be equal to about 3 g of CLA per day. The anti-inflammatory properties of CLA seem to work better in the presence of adequate blood levels of omega-3.



I’m curious how and why a busy cardiothoracic surgeon would transform his practice so dramatically. Was there a specific event that triggered your change?

The transition from a very busy surgical practice to writing and speaking about the prevention of coronary disease has not been particularly easy, but it has been very interesting. I can't really point to any specific epiphany, it was a general feeling of frustration that we were not making any progress in curing heart disease, which is what I thought I was doing when I began my medical career.

Of course, I enjoyed the technical advances, the dramatic life-saving things that you do and I did on a daily basis. American medicine is spectacularly good at managing crises and spectacularly horrible at preventing those crises.

The lipid hypothesis is old and tired, even the most aggressive statin therapy reduces risk of heart attack by about 30% in a relatively small subset of people. It's interesting that we're now looking at statins as an anti-inflammatory agent.


Thanks, Dr. Lundell. We look forward to future conversations as your experience with CLA and heart disease prevention and reversal develops!

High-tech heart attack proofing


I was reminiscing the other day about what I was taught about heart disease in medical school some 20 years ago.

In the 1980s, the world was still (and remains) fascinated with this (then) novel "solution" to heart disease called coronary bypass surgery. As medical students, we all fought for a chance to watch a bypass operation being performed. And there was lots of opportunity. I was a medical student at St. Louis University School of Medicine, a center that boasted of a busy thoracic surgery service, performing up to 10 bypass operations every day.

Back then, coronary angioplasty was just a twinkle in Andreas Gruentzig's eye, still contemplating whether it was possible to put an inflatable device in the blockages of coronary arteries to re-establish blood flow. Risk detection for heart disease consisted of EKGs, screening for symptoms, detection of heart failure, and tests that are long forgotten in the dust bin of medical curiosities, tests like systolic-time intervals, phonocardiography (using amplified sound to detect abnormal heart sounds), and detailed physical examination. Treatment for heart attack involved nitroglycerin and extended bedrest. Bypass surgery would come after you recovered.

In other words, NONE of the tools we now use in the Track Your Plaque program for heart disease control and reversal were available just twenty years ago. There was no lipoprotein testing, no CT heart scans. Nobody recognized the power of omega-3 fatty acids (although epidemiologic observations were just beginning to suggest that eating fish might be the source of reduced risk for heart attack and cardiovascular death). Vitamin D? Why, that's in your milk so your babies don't get rickets.

So much of what we do today was not available then, nor were they even in the crystal ball of forward-looking people. I certainly had no idea whatsoever that I'd be talking and obsessing today about reversal of heart disease based on what I saw and learned back then.

Things have certainly come a long way and all for the better. The problem is that much of the world is stuck in 1985 and haven't yet heard that coronary disease is a manageable and reversible process. They've been sidetracked by the fiction propagated by the likes of Dr. Dean Ornish, the nonsense of low-fat diets aided and abetted by the food manufacturing industry and the USDA, the extravagant claims of some practitioners and the supplement industry. They haven't yet stumbled on the real-life experiences that are chronicled here in this Blog and the accompanying Track Your Plaque website.

Our program has been criticized for being too "high-tech," involving too many sophisticated measures like small LDL, lipoprotein(a) treatment, vitamin D blood levels. But when you see a woman reduce her heart scan score 63%, or a school principal's score plummet 51%, then that's reward in itself.

It's all about plaque

Just to keep my finger on the pulse of what is being said in the world of heart disease by the media, I subscribe to many publications.

Conversations abound about cholesterol, low-fat diets, now low-carb diets, not smoking, inflammation, etc. No doubt, these all have some importance in the conversation.

But the great majority of discussions fail to identify the one truly crucial factor to identify and track: coronary atherosclerotic plaque.

Sugar for breakfast

We were reviewing Stuart's diet because of his persistent small LDL, low HDL, modestly elevated triglycerides, and blood sugar of 107 mg/dl.

"I've changed my diet, doc. No kidding. We never fry our foods. No butter, no goodies. I don't know what else I can possibly do."

"Okay. Let's review your diet. What did you have for breakfast?"

"Orange juice, a big glass. Gotta get my potassium. Then cereal like Cheerios or Shredded Wheat, sometimes Kashi or Raisin Bran, always in skim milk. Gotta have my one slice of toast, no butter. I'll put some fruit preserves on it. You know, real fruit. Only whole wheat bread, never white. On Sundays, we always go out for pancakes, but now we order only whole wheat."

Many of us have gotten into a peculiar habit: Having what amounts to pure sugar for breakfast. Perhaps there's a little fiber thrown in with it, but many people indulge in breakfasts that are sugar and plenty of it. That's precisely what Stuart is doing: A breakfast that, while it doesn't contain a huge amount of sugar outside of the orange juice, is promptly converted to sugar. If we were to check his blood sugar just after his standard breakfast, it would rise substantially.

This pattern has become deeply ingrained into the American psyche. Some people will act like I've suggested we overthrow the government when I suggest that breakfast cereals need to be eliminated from their lives. We all share memories of Tony the Tiger, the leprechaun on Lucky Charms ("They're magically delicious!), reading the brightly colored boxes often including games and prizes. Breakfast cereals seem as American as apple pie. But the wheat and corn content ensures a big rise in blood sugar, the sort that create small LDL, low HDL, etc.--all the patterns Stuart is showing--and make us fat.

Orange juice? Too much sugar all at once. Get your potassium from whole vegetables and fruits, not from orange juice. (Bananas are another problem source of potassium for similar reasons despite being a whole fruit.)

Toast? Any diabetic who monitors their blood sugar after meals will tell you: Even one slice of bread, ANY bread, skyrockets blood sugar. Add the fruit preserves made with sugar syrup and it's doubly worse.

Pancakes? Even if made with plenty of fiber, blood sugars go absolutely berserk after a meal like this, especially if maple syrup is added.

In other words, the seemingly healthy breakfast Stuart eats guarantees that he fails to control all his patterns that contribute to his coronary plaque growth.

After I pointed out Stuart's dietary faux pas, he asked, "Then what the heck can I eat?"

"There's actually lots of good choices: Eggs (preferably free-range, if available, or the 'omega-3' enriched) or Egg Beaters; oat products, but true oat products like slow-cooked oatmeal, or the best of all, oat bran, used as a hot cereal; ground flaxseed as a hot cereal with added fruit, berries, nuts; a handful of raw almonds, walnuts, pecans; some cheese, preferably traditional fermented cheese and not processed; low-fat cottage cheese; low-fat yogurt that you flavor yourself with berries and nuts; raw seeds like sunflower and pumpkin.

"Try and save some of your dinner foods for breakfast. For instance, save some green peppers and onions from your salad and put it in your scrambled eggs along with some olive oil. Save some of the chicken and add it to your breakfast. Save some of the cooked vegetables and have them as they are. You'll be surprised how filling dinner foods can be when eaten for breakfast."

It's not that tough. But Stuart and many other people need to break the hold that the food manufacturers have created. If you're hoping to seize hold of your heart scan score, get rid of the sugar foods in your morning, even the ones cleverly disguised as healthy.

The Low-Carb Man

If ever there was an enthusiastic disciple of deceased Dr. Robert Atkins of Atkins' Diet fame, it's Mr. Jimmy Moore.








Jimmy tells the story of how he was transformed by the Atkins' approach, losing 180 lbs in the course of one year. He continues to develop this conversation, in many ways elaborating on the conversation in more sophisticated ways than even Atkins did in his lifetime.

Though we've agreed to disagree on some points of nutrition, Jimmy and I had a recent discussion about heart disease, the mis-guided ways of conventional cardiac care,and the evils of processed carbohydrates. We do differ on the role of saturated fat in heart disease and health, but beyond that difference I was impressed (reading his Blog and listening to his many webcasts) with his level of understanding of the issues. Jimmy is not some over-enthusiastic dieter. He has a grasp of the issues that exceeds that of 99% of my colleagues.

If you are interested in reading our discussion or just perusing a really fun, informative Blog/website, go to LivinLaVidaLowCarb.com. The interview is posted at:

Why average cholesterol values can be so bad

Jack had been told again and again that there was absolutely nothing wrong with his cholesterol panel. His numbers:

Total cholesterol 198 mg/dl

LDL cholesterol 119 mg/dl--actually below the national average (131 mg/dl).

HDL 48 mg/dl--actually above the average HDL for a male (42 mg/dl).

Triglycerides 153 ng/dl--right at the average.


So his primary care physician was totally stumped when Jack's heart scan revealed a score of 410.


Lipoprotein analysis (NMR) told an entirely different story:

LDL particle number 1880 nmol/l (take off the last digit to generate an approximate real LDL, i.e., 188 mg/dl).

Small LDL 95% of all LDL particles, a very severe pattern.

A severe excess of intermediate-density lipoprotein (218 nmol/l), suggesting that dietary fats are not cleared for 24 hours or so after a meal.

And those were just the major points. In other words, where conventional cholesterol values, or lipids, failed miserably, lipoprotein analysis can shine. The causes for Jack's high heart scan score become immediately apparent, even obvious. Jack's abnormalities are relatively easy to correct--but you have to know if they're present before they can be corrected. A shotgun statin drug approach could only hope to correct a portion of this pattern, but would unquestionably fail to fully correct the pattern.

As I've said before, standard cholesterol testing is a fool's game. You can squeeze a little bit of information out of them, but there's so much more information that can be easily obtained through lipoprotein testing like Jack had.

Cholesterol trumps heart scan?

Lela's heart scan score: 449--very high for a 49-year old, peri-menopausal woman. Her score placed her flat in the 99th percentile, or the worst 1% of women her age.

Lela first consulted her primary care physician. Her doctor looked at the result puzzled. "Now wait a minute. Your cholesterol numbers have been great." After a pause, her doctor (a woman) declared the heart scan wrong. "Tests aren't perfect. The heart scan is simply wrong. I'm going to believe the cholesterol numbers and there's no way you have heart disease."

Is that right? Can cholesterol numbers trump your heart scan score? Can the heart scan simply be wrong?

The answer is simple: NO.

The heart scan is not wrong. The heart scan is right. What is wrong with this picture is that standard cholesterol testing commonly and frequently fails to identify people at risk for heart disease.

What if this woman smoked? That wouldn't be revealed in her cholesterol panel. Or had high blood pressure, increased inflammatory responses like C-reactive protein, had increased small LDL or lipoprotein(a), was severely deficient in vitamin D? None of that would be revealed by cholesterol numbers.

So, no, the heart scan is not wrong. The cholesterol numbers are not wrong. The doctor's interpretation of the data is wrong.

Please do not allow false reassurances offered by those who do not understand the technology steer you wrong.

This woman proved to have an entire panel of hidden causes of her coronary plaque uncovered. No surprise.

Boycott LabCorp

Track Your Plaque Members have been following this conversation on the Track Your Plaque Forum.

A good number of people have had their blood drawn for NMR lipoprotein analysis through laboratories operated by the Laboratory Corporation of American, or LabCorp. When the results were returned, the very important page 2 of the report was withheld. Many of us have communicated with the company, only to be given some corporate-speak about internal policy.

I have personally expressed my dissatisfaction, my outrage, at this silly policy. Why would laboratory results that you or your insurance paid for be denied to you? It is my understanding that, on request, you are legally entitled to the information. The page 2 information is provided by the laboratory (Liposcience, Inc.) that actually performs the testing. LabCorp does nothing more than draw the blood, prepare the specimen, then convey and dilute the results that Liposcience reports to them.

My personal suspicion is that the LabCorp people do this to 1) make the results appear that they actually performed the tests and not farmed to an outside laboratory (Liposcience), and 2) not further confuse and befuddle the bungling primary care physician who barely understands cholesterol issues to begin with. "LDL, HDL, triglycerides . . . What now--a bunch of new information, bars even!?

To me, this LabCorp policy is criminal. In fact, I wonder if this has the substance to justify a class action lawsuit against LabCorp. I believe that we can easily make a case that crucial health information is being systematically denied to people.

If this has affected you, or if you share in the frustration of many people who have had watered down lipoprotein results provided, write to:


Ken Younts, VP of Sales at LabCorp. Yountsk@labcorp.com


Or, write to:

Thanks to the Track Your Plaque Members who have already participated in this campaign and written to the LabCorp people. And thanks to our Members who uncovered the contact information.

Until then, please BOYCOTT LABCORP LABORATORIES. Please do not use LabCorp Laboratories if you can avoid it. Simply ask the laboratory staff who operates the lab and they should tell you. It is your right to know.

Useless low-fat diets

If you would like to read an ironic testimonial to the futility of conventional low-fat diets, read:

Cutting Cholesterol, an Uphill Battle on the New York Times website at http://www.nytimes.com/2007/08/21/health/21brod.html?_r=2&adxnnl=1&oref=slogin&ref=health&adxnnlx=1187928650-f0mfyzGTFdsLmtInHcGPUw

In this story, author and columnist Jane Brody recounts her struggles with her cholesterol levels. She describes how she followed an increasingly strict low-saturated fat diet, hoping to reduce LDL cholesterol. But she saw the opposite occur: LDL climbed from an initial 134 to 171, a level that caused her doctor to prescribe a statin drug.

Yet she states that "About 85 percent of the cholesterol in your blood is made in your body. The remaining 15 percent comes from food. But by reducing dietary sources of saturated fats and cholesterol and increasing consumption of cholesterol-fighting foods and drink, you can usually lower the amount of harmful cholesterol in your blood."

Had Ms. Brody and her doctor been just a bit better informed and performed lipoprotein analysis instead, they would have seen some obvious phenomena:

--All the increase in LDL was in the fraction of small particles, the sort highly likely to cause heart attack.

--The conventional LDL that she quotes is a calculated value that miserably misrepresents the real LDL when actually measured. Her calculated LDL of 171 mg/dl, in fact, was probably more like 220 to 250 mg/dl--much higher than they think.


Of course, Ms. Brody turns to her conventionally-thinking physician who then predictably prescribes a statin drug.

Ms. Brody's well-articulated story achieves the ironic, unintended result of proving the idiocy of the conventional low-fat diet. The low-fat diet, as currently practiced by most people, raises LDL cholesterol and escalates risk for heart disease. In fact, Ms. Brody probably increased her risk far more than suggested by a 30 mg increase in LDL.

One of my favorite blogs, the Fanatic Cook, has a tremendously insightful post on Ms. Brody's misadventures.

If all she did was eliminate all wheat flour containing products and reduce the overall glycemic index of her diet, she would witness an enormous drop in LDL cholesterol, both calculated and measured.

I hope that Ms. Brody survives her diet mistakes and her doctor's ignorance.

Genetic vs. lifestyle small LDL

Let me explain what I mean by "genetic small LDL." I think it helps to illustrate with two common examples.

Ollie is 50 years old, 5 ft 10 inches tall, and weighs 253 lbs. BMI = 36.4 (obese). Starting lipoproteins (NMR):

LDL particle number 2310 nmol/L
Small LDL: 1893 nmol/L
(1893/2310 = 81.9% of total, a severe small LDL pattern)


Stan is 50 years old, also, 5 ft 10 inches tall, and weighs 148 lbs. BMI = 21.3. Starting lipoproteins:

LDL particle number 1424 nmol/L
Small LDL 1288 nmol/L
(1288/1424 = 90.4% of total, also severe)


Both Ollie and Stan go on the New Track Your Plaque diet and eliminate wheat, cornstarch, and sugars, while increasing oils, meats and fish, unlimited raw nuts, and vegetables. They add fish oil and vitamin D and achieve perfect levels of both. Six months later, Ollie has lost 55 lbs, Stan has lost 4 lbs. A second round of lipoproteins:

Ollie:

LDL particle number 1810 nmol/L
Small LDL: 193 nmol/L
(193/1810 = 10.6% of total)


Stan:

LDL particle number 1113 nmol/L
Small LDL 729 nmool/L
(729/1113 = 65.4% of total)


Ollie has reduced, nearly eliminated, small LDL through elimination of wheat, cornstarch, and sugars, along with weight loss, fish oil, and vitamin D.

Stan, beginning at a much more favorable weight, reduced both total and small LDL with the same efforts, but retains a substantial proportion (65.4%) of small LDL.

Stan's pattern is what I call "genetic small LDL." Of course, this is a presumptive designation, since we've not identified the specific gene(s) that allow this (e.g., gene for variants of cholesteryl ester transfer protein, hepatic lipase, lipoprotein lipase, and others). But it is such a sharp distinction that I am convinced that people like Stan have this persistent pattern as a genetically-determined trait.

Carbohydrate sins of the past

Fifty years ago, diabetes was a relatively uncommon disease. Today, the latest estimates are that 50% of Americans are now diabetic or pre-diabetic.

There are some obvious explanations: excess weight, inactivity, the proliferation of fructose in our diets. It is also my firm belief that the diets advocated by official agencies, like the USDA, the American Heart Association, the American Dietetic Association, and the American Diabetes Association, have also contributed with their advice to eat more “healthy whole grains.”

When I was a kid, I ate Lucky Charms® or Cocoa Puffs® for breakfast, carried Hoho’s® and Scooter Pies® in my lunchbox, along with a peanut butter sandwich on white bread. We ate TV dinners, biscuits, instant mashed potatoes for dinner. Back then, it was a matter of novelty, convenience, and, yes, taste.

What did we do to our pancreases eating such insulin-stimulating foods through childhood, teenage years, and into early adulthood? Did our eating habits as children and young adults create diabetes many years later? Could sugary breakfast cereals, snacks, and candy in virtually unlimited quantities have impaired our pancreas’ ability to produce insulin, leading to pre-diabetes and diabetes many years later?

A phenomenon called glucose toxicity underlies the development of diabetes and pre-diabetes. Glucose toxicity refers to the damaging effect that high blood sugars (glucose) have on the delicate beta cells of the pancreas, the cells that produce insulin. This damage isirreversible: once it occurs, it cannot be undone, and the beta cells stop producing insulin and die. The destructive effect of high glucose levels on pancreatic beta cells likely occurs through oxidative damage, with injury from toxic oxidative compounds like superoxide anion and peroxide. The pancreas is uniquely ill-equipped to resist oxidative injury, lacking little more than rudimentary anti-oxidative protection mechanisms.

Glucose toxicity that occurs over many years eventually leaves you with a pancreas that retains only 50% or less of its original insulin producing capacity. That’s when diabetes develops, when impaired pancreatic insulin production can no longer keep up with the demands put on it.

(Interesting but unanswered question: If oxidative injury leads to beta cell dysfunction and destruction, can antioxidants prevent such injury? Studies in cell preparations and animals suggest that anti-oxidative agents, such as astaxanthin and acetylcysteine, may block beta cell oxidative injury. However, no human studies have yet been performed. This may prove to be a fascinating area for future.)

Now that 50% of American have diabetes or pre-diabetes, how much should we blame on eating habits when we were younger? I would wager that eating habits of youth play a large part in determining potential for diabetes or pre-diabetes as an adult.

The lesson: Don’t allow children to repeat our mistakes. Letting them indulge in a lifestyle of soft drinks, candy, pretzels, and other processed junk carbohydrates has the potential to cause diabetes 20 or 30 years later, shortening their life by 10 years. Kids are not impervious to the effects of high sugar, including the cumulative damaging effects of glucose toxicity.

Saturated fat and large LDL

Here's a half-truth I often encounter in low-carb discussions:

Saturated fat increases large LDL particles


For those of you unfamiliar with the argument, I advocate a low-carbohydrate approach, specifically elimination of all wheat, cornstarch, and sugars, to reduce expression of the small LDL pattern (not to mention reduction of triglycerides, relief from acid reflux and irritable bowel, weight loss, various rashes, diabetes, etc). Small LDL particles have become the most common cause for heart disease in the U.S., exploding on the scene ever since agencies like the USDA and American Heart Association have been advising the public to increase consumption of "healthy whole grains."

This has led some to make the pronouncement that saturated fat increases large LDL, thereby representing a benign effect.

Is this true?

It is true, but only partly. Let me explain.

There are two general categories of factors causing small LDL particles: lifestyle (overweight, excess carbohydrates) and genetics (e.g., variants of the gene coding for cholesteryl-ester transfer protein, or CETP).

If small LDL is purely driven by excess carbohydrates, then adding saturated fat will reduce small LDL and increase large LDL.

If, on the other hand, your small LDL is genetically programmed, then saturated fat will increase small LDL. In other words, saturated fat tends to increase the dominant or genetically-determined form of LDL. If your dominant genetically-determined form is small, then saturated fat increases small LDL particles.

So to say that saturated fat increases large LDL is an oversimplification, one that can have dire consequences in the wrong situation.

Is glycemic index irrelevant?



University of Toronto nutrition scientist, Dr. David Jenkins, was the first to quantify the phenomenon of "glycemic index," describing how much blood sugar increased over 90 minutes compared to glucose. The graph is from their 1981 study, The glycemic index of foods: a physiologic basis for carbohydrate exchange. The research originated with an effort to characterize carbohydrates for diabetics to gain better control over blood sugar.

Since Dr. Jenkins’ original work, thousands of clinical studies have been performed by others exploring this concept. The food industry has also devoted plenty of effort exploiting it (e.g., low-glycemic index noodles, low-glycemic index cereals, etc.).

Most Americans are now familiar with the concept of glycemic index. You likely know that table sugar has a high glycemic index (60), increasing blood sugar to a similar degree as white bread (glycemic index 71). Oatmeal (slow-cooked) has a lower glycemic index (48), since it increases blood sugar less than white bread.

A number of studies have shown that when low glycemic index foods replace high glycemic index foods (e.g., whole wheat bread in place of cupcakes), people are healthier: less diabetes, less heart attack, less high blood pressure. Books have been written about glycemic index, touting its benefits for health and weight control. Health-conscious people will try to substitute low-glycemic index foods for high-glycemic index foods.

So what’s not to like here?

There are several fundamental flaws with the notion that low-glycemic index foods are good for you:

1) Check your blood sugar after a low-glycemic index food like oatmeal. Most non-diabetic adults will show blood sugars in the 140 to 200 mg/dl range. The more central (visceral) fat you have, the higher the value will be. In other words, an apparently “healthy” whole grain food like oatmeal can generate extravagantly high blood sugars. Repeated high blood sugars of 125 mg/dl or greater after eating increase heart disease risk by 50%.

2) Foods like whole wheat pasta have a low glycemic index because the blood sugar effect over the usual 90 minutes is increased to a lesser degree. The problem is that it remains increased for an extended period of up to several hours. In other words, the blood sugar-increasing effect of pasta, even whole grain, is long and sustained.

3) Low-glycemic index foods trigger other abnormalities, such as small LDL particles, triglycerides, and c-reactive protein (a measure of inflammation). While they are not as bad as high-glycemic index foods, they are still quite potent triggers.

Low-glycemic index foods trigger the very same responses as high-glycemic index foods—they’re just less bad. But less bad does not equate to good. Low-glycemic index foods cause weight gain, trigger appetite, increase blood pressure, and lead to the patterns that cause heart disease.

High-glycemic index foods are bad for you. This includes foods made with white flour (bagels, white bread, pretzels). Low-glycemic foods (whole grain bread, whole wheat crackers, whole wheat pasta) are less bad for you—but they are not necessarily good.

Don’t be falsely reassured by foods because they are billed as “low-glycemic index.” View low-glycemic index foods as indulgences, something you might have once in a while, since a slice of whole grain bread is really not that different from a icing-covered cupcake.

What Mr. Clinton did NOT do

You've likely already heard that former President Bill Clinton underwent a heart catheterization today during which one of the bypass grafts to his coronary arteries was found to be occluded. The original coronary artery was therefore stented.

Dr. Alan Schwartz, Mr. Clinton's cardiologist, announced to the gathered press that Mr. Clinton had followed a good diet, had adopted a regular exercise program, but that his condition is a "chronic disease" like hypertension that is not cured by these efforts.



Needing a stent just 6 years after four bypass grafts are inserted is awfully soon. I would propose that it has less to do with having a "chronic disease" and more to do with all the things that Mr. Clinton likely is NOT doing. (In addition to all the other things that Mr. Clinton did not do.) In other words, in the Track Your Plaque world, procedures are a rarity, heart attacks virtually unheard of. I would wager that Mr. Clinton has been doing none of the following:

--Taking fish oil. Or, if his doctor was "advanced" enough to have advised him to take fish oil, not taking enough.
--Vitamin D--Followers of the Heart Scan Blog already know that vitamin D is the most incredible health find of the last 50 years, including its effects on reducing heart disease risk. Unless Mr. Clinton runs naked in a tropical sun, he is vitamin D deficient. A typical dose for a man his size is 8000 units per day (gelcap only!).
--Eating a true heart healthy diet. I'll bet Mr. Clinton's doctor, trying to do the "right" thing, follows the prudent course of advising a "balanced diet" that is low in fat--you know, the diet that causes heart disease. Judging by Mr. Clinton's body shape (central body fat), it is a virtual certainty that he conceals a severe small LDL pattern, the sort that is worsened by grains, improved with their elimination.
--Making sure that hidden causes are addressed--In addition to the "hidden" small LDL, lipoprotein(a) is another biggie. Lp(a) tends to be the province of people with greater than average intelligence. I believe Mr. Clinton qualifies in this regard. I would not be at all surprised if Mr. Clinton conceals a substantial lipoprotein(a) pattern, worsened in the presence of small LDL.
--Controlling after-meal blood sugars--Postprandial (after-eating) blood sugars are a major trigger for atherosclerotic plaque growth. There are easy-to-follow methods to blunt the after-meal rise of blood sugar. (This will be the subject of an in-depth upcoming Track Your Plaque Special Report.)
--Thyroid normalization--It might be as simple as taking iodine; it might involve a little more effort, such as supplemental T3. Regardless, thyroid normalization is an easy means to substantially reduce coronary risk and slow or stop coronary plaque growth.


It's not that tough to take a few steps to avoid bypass surgery in the first place. Or, if you've already had a procedure, a few additional steps (of the sort your doctor will likely not tell you about) and you can make your first bypass your only bypass.

Magnesium and arrhythmia

Because magnesium is removed during municipal water treatment and is absent from most bottled water, deficiency of this crucial mineral is a growing problem.

Magnesium deficiency can manifest itself in a wide variety of ways, from muscle cramps (usually calves, toes, and fingers), erratic blood sugars, higher blood pressure, to heart rhythm problems. The abnormal heart rhythms that can arise due to magnesium deficiency include premature atrial contractions, premature ventricular contractions, multifocal atrial tachycardia, atrial fibrillation, and even ventricular tachycardia, fibrillation, and Torsade de Pointes (all potentially fatal). Magnesium is important!

Magnesium supplementation is therefore necessary for just about everybody to maintain normal tissue levels. (The exception is people with kidney disorders, who should not take magnesium without supervision, since they retain magnesium.)

Here is a Heart Scan Blog reader's dramatic rhythm-correcting response to magnesium supplementation:



Dr. Davis,

A few months ago, I contacted you inquiring if you had written any articles on arrhythmia. You were generous enough to answer and guide me to an LEF article you'd written in which you stressed fish oil and magnesium. I had been suffering with bad PVCs [premature ventricular contractions] for over 20 years, and they had gotten so bad recently that I was told my next options were ablation or pacemaker!

I was already on fish oil and had not seen any difference, and so I researched the magnesium you suggested more thoroughly and found a huge body of studies supportng its effect on arrhythmia. I also read many posts on heart forums with people having success with it. After getting advice from various bloggers, I tried magnesium taurate in the morning and Natural Calm (an ionized form of mag citrate) in the afternoon and evening. Within three days the PVCs were quite diminished and by 2 weeks totally gone! As long as I keep taking it, they never return---not even one irregular blip---even when I drink strong coffee! The magnesium also cleared up my restless leg syndrome, my eye twitching, and insomnia. (Apparently, I was the poster-girl for magnesium deficiency.)

I am so angry that after all these years of suffering, trying various medications, and seeing at least 4 different cardiologists that NOT ONE ever even mentioned trying magnesium. The generosity of the few minutes you took to answer my email and steer me in a helpful direction brought me total relief.

Thank you SO MUCH!

Warmly,
Catherine C.

Thinner by Thursday

You want to lose a few pounds . . . Okay, maybe 50 or 75.

Should you exercise? Lengthen you workout? Push the plate away, deny yourself seconds, use a smaller plate?

Of all the weight loss strategies I've tried in patients, there's only one that stands out as a means of obtaining immediate--meaning within 3 days--weight reduction.

Wheat elimination.

Omega-3 Index: 10% or greater?

We've previously considered the question:

What is an ideal level of omega-3 fatty acids in the blood?

Recall that omega-3 levels in red blood cells (RBCs), a measure called the "omega-3 index," have been associated with risk for sudden cardiac death:





In a recent analysis, 265 people experiencing sudden death during a heart attack (ventricular fibrillation, successfully resuscitated) showed an omega-3 index of 4.88%, while 185 people not experiencing sudden death during a heart attack showed an omega-3 index of 6.08%.

We have more ambitious goals than just avoiding sudden death, of course! How about the omega-3 index associated with reduced risk for heart attack? A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks, suggesting that even higher levels are necessary to prevent non-fatal events.

Most recently, another study comparing 50 people after heart attack with 50 controls showed that people with heart attack had an omega-3 index of 9.57% vs 11.81% in controls--even higher. (This study was in a Korean population with higher fish consumption. There was also a powerful contribution to risk from trans fat RBC levels.) The investigators concluded: "The area under the receiver operating characteristic curve of fatty acid profiles was larger than that for traditional risk factors, suggesting that fatty acid profiles make a higher contribution to the discrimination of MI cases from controls compared with modified Framingham risk factors."

The data suggest that, while an omega-3 index of 7.3% is associated with reduced risk for sudden cardiac death, a higher level of 10% or greater is associated with less risk for heart attack. Surprisingly, fish consumption and fish oil intake account for only 47% of the variation in omega-3 index.

I believe the emerging data are becoming increasingly clear: If you desire maximal control over heart health, know your omega-3 index and keep it 10% or higher.

Let's soak 'em with fish oil

If you don't think that charging drug prices for fish oil is wrong, take a look at a letter from an angry Heart Scan Blog reader:


Hello Dr. Davis,

My 44 year old brother had an MI [myocardial infarction, or heart attack] in June. He got pushed around due to "bad government insurance," a state-run program for the "uninsured": government pays 1/3, job pays 1/3, and individual pays 1/3.

What they didn't tell him is that there is no major medical coverage and little to no prescription coverage. We fought for 4 months to get him open heart surgery that the insurance was not going to pay for.

Now, with no assistance, terrible insurance, and no disability he has little to no income. He is a heavy equipment mechanic and is trying to be the "good American"-- take care of his bills, not file bankruptcy, etc.

Anyway, the doctors never seem to pay attention to what they prescribe. Lipitor was not working for him, due to side effects. Now they want to give him Zetia and Lovaza....Zetia at $114, and Lovoza is $169.85! Wow! For dead fish???? I think this is a little fishy! I looked up Lovaza, gee how nice, they will give you a $20 coupon....

Forget it, he can't afford this stuff. So I am enrolling in the Zetia program for him. And trying to get him OTC [over-the-counter] fish oil. The most prevalent fish oil around here (that I take myself is) Omega 3 Fish Oil that has EPA 410mg, DHA 274.

Thanks for your blog. It made me feel better that I wasn't the only one outraged by this stuff. I 've been a nurse for 20 years and it just never seems to get better. Thank you for your wisdom.

Sincerely JP, Tennessee



Had this reader not been aware that her brother could take fish oil as a nutritional supplement, he likely would have been denied the benefit of omega-3 fatty acids in slashing the risk for recurrent cardiovascular events. You and I can buy wonderfully safe and effective fish oil as a nutritional supplement, but there won't be a sexy drug representative to sell it, nor an expensive dinner and payment for a trip to Orlando to hear about it.
