It doesn't matter what I eat!

"How are your food choices?" I asked.

"What does it matter, doc? I take Lipitor. Doesn't that take care of it? I eat what I want!"

So declared Matthew. What he "wanted" was pretty much the diet of a teenager: pizza, cheeseburgers, soft drinks, snacks. His "beer belly" (visceral fat) gave it away. So did his blood work that showed flagrant lipoprotein abnormalities--small LDL, an HDL of 37 mg, and a severe after-eating flood of fat represented by increased "intermediate-density lipoprotein" (IDL).

Like many people, Matthew had been persuaded (or chose to believe) that LDL cholesterol was the sole cause for heart disease. Lipitor was therefore was all he needed. It must be great--how else could they afford all those slick TV commercials?

Well, it is definitely not true. In fact, with the persistence of Matthew's abnormal lipoprotein patterns, we should expect his heart scan score to continue to grow by 30%--the very same rate of increase as if he were taking nothing.

Specifically, Lipitor and drugs like it do not:

--Raise HDL.

--Correct or reduce the proportion of small LDL.

--Block after-eating flood of fat, nor do they accelerate clearance of unhealthy fats persisting in the bloodstream after eating.


Yes, what you eat does have real consequences, even if you take a statin drugs. In fact, the foods you ingest have a remarkably rapid and dramatic effect on what your blood contains. Any diabetic who checks his/her blood sugar knows this. They eat a slice of whole wheat toast and watch their blood sugar skyrocket.

Mind what you eat. Make it enjoyable, of course. But drugs do not provide impunity.

People with higher scores need to try harder

Sam is a 69-year retired physician. He was thoroughly enjoying retirement: golf, travelling, going out to dinner two or three times a week, spending weekends with his grandchildren. His lifestyle tended towards overindulgence, but he managed to stay fit and trim. At 6 ft 1 inch, he weighed 194 lbs and could still run 3 miles without too much difficulty. Not as good as his marathon-running days, but still not too bad for 69.

Sam's heart scan score in 2003 was a concerning 1983--extensive plaque. His doctor wasn't much help in interpreting the scan and so Sam simply chose to ignore it.

A chance conversation with a physician friend 18 months later made Sam think that perhaps this shouldn't be ignored. That's when he came to my office.




I find that sometimes the best way to motivate someone to take action is to demonstrate just how fast plaque grows if action isn't taken. So I advised Sam to get another scan first, since 18 months had passed. His score: 2441, or a 23% increase.




Sam was now starting to catch on. We made several changes in his prevention program (starting from virtually nothing). He did undergo a stress nuclear (thallium type) of test, which he passed without difficulty--normal blood flow in all heart territories despite the extensive plaque.

But, for some reason, Sam simply allowed himself to drift back to old habits: poor choices in food, overindulging in hard liquor, missing his fish oil and other supplements, and his medication, sometimes up to several days a week.

Sam started having unusual feelings in his chest. He described a sort of nervousness along with skipped heart beats. So we repeated a stress test. This time, a large area of reduced blood flow in the front of his heart ("anterior left ventricle") was detected. Sam ended up receiving three stents in a difficult procedure.

The moral: If you're starting out with a lower heart scan score of, say, 100 or 200, maybe you'll get by without trying too hard--maybe. But if your score is higher, say, several hundred or in the thousands, you got to try harder.

You're starting later in the process. Your disease will allow you very little slack. Let your guard down and it will get you. Control over your plaque is, indeed, very possible--we do it all the time. Score reduction is also possible. But your effort must be more serious and consistent.

Money can't buy health

Fallen Enron CEO, Kenneth Lay, was pronounced dead early this a.m. after suffering a heart attack.

Mr. Lay apparently had no history of heart disease and there's been no indication that symptoms provided any warning. His death was therefore classified as "sudden cardiac death".


Yet here's a man previously worth hundreds of millions of dollars with access to any test or medical system he desired--many times over. Even more recently, with his wealth reduced following his legal troubles, he and his wife managed to put away $4 million dollars to ensure an income from the interest through annuities, untouchable by the courts.

Detecting Mr. Lay's heart disease would have cost him around a few hundred dollars or whatever it costs for a CT heart scan in his city. This would have alerted his (hopefully knowledgeable) doctor that he was a time-bomb. Pile on all the stress he'd been suffering, whether deserved or no, and the diagnosis would have required little thought.

Instead, Mr. Lay has joined the thousands of Americans who will die this year because of failing to get a simple, 30-second test that costs one-tenth the cost of a stress test. Mr. Lay wasn't as lucky as former President Bill Clinton, whose doctors likewise blundered their way through and missed obvious levels of heart disease.

All Mr. Lay needed was better information: get a heart scan, then follow a program of prevention like the Track Your Plaque program. You may not have hundreds of millions of dollars, but you have the information on how to not follow in Ken Lay's footsteps. Track Your Plaque--and stay alive.

What's important, what's not in your plaque-control program

Sometimes it's hard to know what is really important in your plaque-control or plaque-reducing efforts.

There are, indeed, crucial make-it-or-break-it factors that are necessary to gain control over plaque. If you hope to stack the odds of reducing your heart scan score as much as possible in your favor, then fish oil, vitamin D, 60-60-60 in the way of standard lipids, elimination of small LDL, etc. -- all the elements of the Track Your Plaque program--are necessary.

But there's lots of things that sidetrack people. I spend much of my day fielding questions from patients about all the things that either provide very little benefit for plaque control, or provide none at all.

Among the things that we have found to be too weak or useless for plaque control, or are "non-issues", include:

--Caffeine--Go ahead and enjoy a couple cups a day (though not a pot). The effect is too trivial to make much difference.

--Hawthorne--Yes, it may dilate coronary arteries modestly, but not enough to make any difference.

--Garlic--with the possible exception of a specific preparation called Aged Garlic Extract (an acqueous, non-oil-based, extract from Kyolic), garlic's effects are too tiny to help, e.g., drop in blood pressure 1-2 points. Use it, but don't expect much. Aged Garlic Extract may be an exception, in that a single study from UCLA suggested specific effects on slowing coronary plaque growth. We await more info on this.

--Anti-oxidants--There is no shortage of extravagant claims about the benefits of anti-oxidants. Unfortunately, there's very little human exerience with pine bark extract, pycnogenol, grapeseed extract, and so on. Is the purported benefit from anti-oxidation or through some other means, e.g., enhancement of nitric oxide synthase? No data.

--Policosanol--If you've followed the Track Your Plaque Special Reports, you already know what a disappointment this agent has been, despite the too-good-to-be-true clinical data. It doesn't work.

--"No-flush niacin"--Unfortunately, no flush, no effect. This high-priced supplement is still sold widely in the U.S. despite its complete lack of efficacy. It does not work in humans. (It works great in rats!)

Track Your Plaque continues to try to be the arbiter of truth in what works, what doesn't in truly stopping or reversing your coronary plaque. The proof positive? Stopping or dropping your heart scan score.

Protecting the right to use bio-identical hormones in your heart disease prevention program

If you've been following the Track Your Plaque program, you know that we are advocates of "bio-identical hormones", i.e., hormone replacement using forms that are identical to the naturally-occuring human form.

In other words, we find it criminal that pharmaceutical manufacturers continue to promote use of non-identical hormones despite a probable increased side-effect and complication profile (a la Premarin). This unhappy situation persists because bio-identical hormones cannot be patent protected, meaning profits cannot be protected. Synthetic hormones can be patented and profits protected, thus their popularity among drug companies.

If that's not bad enough, Wyeth Pharmaceuticals--maker of synthetic hormone preparations, Premarin and Prempro--has filed an FDA petition to disallow the use of bio-identical hormones as prepared and dispensed by "compounding pharmacies". These are specialty pharmacies that mix and dispense hormones like estrogens (human estradiol, estriol, and estrione) and testosterone. They do so only with a doctor's prescription. Most are members of the Professional Compounding Centers of America (www.pccarx.com), a professional organization devoted to promoting quality-control over compounding practices.

Compounding pharmacies are occasionally guilty of compounding some suspect preparations. Witness the Fentanyl lollipops of 2002 in which the pain medication, Fentanyl, was put into lollipops for patients with chronic pain. This posed obvious dangers to any children who unsuspectingly ate the lollipops.

But the majority of compounding pharmacies are not guilty of such exotic practices. Most are simply pharmacies who might, for instance, mix a specific dermatologic preparation according to the orders of a dermatologist. Likewise with bio-identical hormones.

We have extensive experience with such a pharmacy in Madison, Wisconsin, the Women's International Pharmacy. They have filled hundreds of hormone prescription for us. They are responsible in their dispensing practices, in our experience. In fact, they have been at least as good, if not better, than other pharmacies we've dealt with.

We believe in protecting our rights to prescribe and you to use the choice of hormone preparations you and your doctor desire. This should include bio-identical hormones. The transparent profit motive from Wyeth should raise the hairs on your neck.

If you would like to post your comment to the FDA, there's a little time left. The folks at Womens' International Pharmacy have made it easy by posting links on their website. Go to http://www.womensinternational.com and just follow the instructions.



Here's a sample of some of the objections citizens have raised to Wyeth's petition:


I have been taking bioidentical hormones for two years. Bioidentical Hormones have been a great relief to me without the risk. I consult with my Physician who prescribes bio-identical hormones specifically for me, and my pharmacist prepares them. Without this medication and I would not be able to sleep; I would not be able to work due to the constant hot flashes. Without this medication, I find that I have less tolerance and I am considerably disagreeable. I also have problem with my memory without them. I want the bioidentcial hormones for the health benefits they provide. I urge you to not be swayed by Wyeth's petition. The product Premarin made by Wyeth, is made from pregnant horses not natural sources. Wyeth's hormones have been shown to cause cancer. I would not expect my government and its officials to submit to the highly funded petitioning of a pharmaceutical company who product is threatened by bioidentcial hormones. I do not expect my government to approved Wyeth's petition and leave me no choice of bioidentcial hormones and only the choice of Wyeth's cancer causing drugs Preamrin and Prempro. I ask that the FDA reject Wyeth's petition Docket #2005P-0411.

Another petitioner writes:

As a woman I take exception to Wyeth accusing the Compounding Pharmacy industry of unsafe practices. As a citizen of the United States I expect the FDA to stand up for my rights and the rights of all women who have found or in the future may seek consistent, safe and effective treatment with bioidentical hormones. Eliminating options by bowing to a large pharmaceutical company like Wyeth is not in the public interest and would deprive hundreds of thousands of American women from access to bioidentical hormones. Synthetic hormone replacement has been proven unequivocally unsafe in a government sponsored study and should not be forced as the sole treatment option for women. I hereby request the FDA rule against Wyeth's request. The FDA should not close down the bioidentical option of healthcare. I welcome studies of bioidentical hormones even though they are already FDA-approved and have been working effectively for decades. We already have the proof - hundreds of thousands of women, who over the past two decades have chosen bioidentical hormones based on their physicians' assessments. They are living proof that bioidentical hormones are safer and more effective and reliable than synthetic hormone drugs.

A physician and user of bio-identical hormones writes:

Wyeth, the filer of this complaint, is trying to prevent women from being able to choose less expensive compounded options for hormone replacement. There is medical evidence that in modifying the structure of their drugs (such as Premarin and Prempro) so that they could be patented, they may have introduced factors that cause the health risks identified in the Women's Health Initiative. This complaint appears to be filed for commercial purposes because of the market share that has shifted from Wyeth's products to bio-identical products from compounding pharmacies. If the complaint were upheld, patients and their doctors would not have a choice in hormone treatments. Wythe's commercial strategy of trying to eliminate the 'competition' from compounding pharmacies is against the public interest and in the interest of its own corporate profits. Women and their doctors should be able to choose between patented formulations such as those offered by Wyeth, bioidentical formulas available from compounding pharmacies, and no hormone treatment. I have been taking bio-identical hormones for several years and have had excellent results in improving my symptoms. I have been unable to take other synthetic hormones in the past, and am very concerned that my best treatment option will be taken away.

If you get a 64-slice CT coronary angiogram

With new 64-slice CT scanners popping up everywhere nowadays, be sure to get your heart scan with it.

The new scanners do indeed provide wonderful images of the coronary arteries. But, say you have a 20% blockage in one artery by a coronary angiogram generated on one of these devices. What will you do in 1, 2, or 3 years when you want to know if you have progressed? Should you have the CT angiogram repeated?

Well, if you did you'll be exposed to a large dose of radiation--appropriate for a diagnostic test, but not for a screening test. The radiation exposure is not that different from undergoing a full conventional cardiac catheterization, or up to 100 chest x-rays.

"20% blockage" is also, contrary to popular opinion, not a quantitative measure. It is just an estimate of the diameter reduction at one spot. That number says nothing about the lengthwise extent of plaque. It also says nothing about the potential for "remodeling", the phenomenon of artery enlargement that occurs as plaque grows. In other words, if you had another CT coronary angiogram a year later and was told that your blockag was still 20%, in reality you could have had substantial plaque growth but it would not be reflected in that value.

People will come to me after having a CT angiogram for an opinion. Unfortunately, I send them back to their scan center to get a simple coronary calcium score. That measure is easy, quantitative, precise, and can be repeated yearly if necessary to track progression. (Track Your Plaque--I hope most of you get this by now.) Some physicians poke fun at the heart scan, or calcium, score--it's old, boring, only a measure of hard plaque. None of that's true. The coronary calcium score is a measure of total plaque (hard and soft). And when you are empowered to learn how to control and reduce your score, then it's the most exciting number in your entire health program!

Don't fall for the hype. If you go to a scan center and they insist on a 64-slice CT scanner, or if your doctor orders one, you should insist on getting a calcium score out of the test. Just ask. If they refuse, go somewhere else. Centers that refuse to generate a score have one thing on their mind: identifying people with severe blockages sufficient to obtain the downstream financial bonanza--angioplasty, stents, and bypass surgery.

If you have hypertension, think Lp(a)

Clair has coronary disease.

Clair first came to attention at age 57 when she suffered a large heart attack involving the front of her heart (the "anterior wall") two years ago. Her cardiologist implanted a drug-coated stent. Her doctors advised her to "cut the fat" in her diet, exercise, and take Lipitor.

One year later, she required a stent to another artery (circumflex). At this point, Clair was thoroughly demoralized and terrified for her future. Her first heart attack left her heart muscle with only 50% of normal strength.

She came to my office for another opinion. Of course, one of the first things we did was to identify all causes of her heart disease. No surprise, Clair had 7 new causes not previously identified, including low HDL (37 mg/dl), a severe small LDL particle pattern (75% of all particles were small), and Lp(a).

Her blood pressure was also 190/88, despite her relatively slender build and 3 medications that reduced blood pressure. That's a Lp(a) effect: Exagerrated coronary risk along with unexpected hypertension that often seems inappropriate.

In fact, I saw several patients just this week with lipoprotein(a), Lp(a), and exagerrated high blood pressure (hypertension). It's not that uncommon.

Though it has not been described in the medical literature, our experience is that hypertension is a prominent part of the entire Lp(a) "syndrome".

Lp(a) is responsible for much-increased potential for coronary disease (coronary plaque). It increases in importance as estrogen recedes in a woman (pre-menopause and menopause) and testosterone in a man, since both hormones powerful suppress Lp(a) expression (though why and how nobody knows).

I believe that Lp(a) is also responsible for hypertension that most commonly develops in a persons mid-50s and onwards, often with a vengeance. 3 or 4 anti-hypertensive medications and still not controlled.



Role of l-arginine

L-arginine may be more helpful in this situation than others. L-arginine, recall, is the supply for your body's nitric oxide, a powerful dilator of the body's arteries and thereby reduces blood pressure. We use 6000 mg twice a day, a large dose that requires use of powder preparations rather than capsules.

More reading about l-arginine and nitric oxide is available through Nobel laureate, Dr. Louis Ignarro's book, NO More Heart Disease : How Nitric Oxide Can Prevent--Even Reverse--Heart Disease and Stroke, available at Amazon.com ( http://www.amazon.com/gp/product/0312335814/104-1247258-6443909?v=glance&n=283155).




Will l-arginine truly reverse heart disease on its own? No, I don't believe so. Contrary to Dr. Ignarro's extravagant claims, I find l-arginine a facilitator of plaque regression, i.e, it helps other strategies achieve regression, but it does not achieve regression or reversal by itself. (Note that Dr. Ignarro is a lab researcher who studies rats and has never treated a human being.)

But l-arginine may have special application in the person with lp(a), particularly if hypertension is part of the syndrome.


Note: As always, please note that I talk frankly about l-arginine and other supplements and medications but have no hidden agenda: I am not selling anything, nor am I affiliated with any source/website/store etc. that sells these products. If I advocate something, I do so because I truly believe it, not because I'm trying to sell something. I make this point because so much nonsense is propagated in the media because of profit-motive. That's not true here.

Dr. Ornish: Get with the program!


In the era up until the 1980s, most Americans indulged in excessive quantities of saturated fats: fried chickem, spare ribs, French fries, gravy, bacon, Crisco, butter, etc.

Along came people like Nathan Pritikin and Dr. Dean Ornish, both of whom were vocal advocates of a low-fat nutritional approach. In their programs, fat composed no more than 10% of calories. This represented a dramatic improvement--at the time.


In 2006, a low-fat diet is a perversion of health. It means over-reliance on breads, breakfast cereals, pasta, crackers, cookies, pretzels, etc., the foods that pack supermarket shelves and that now constitute 70-80% of most Americans' diet.

Dr. Ornish still carries great name recognition. As a result, his outdated concepts still gain media attention. The June, 2006 issue of Reader's Digest, in their RDHealth column, carried an interview with Dr. Ornish in which he reiterates his fat-phobia.

However, on this occasion he takes a different tack. This time he rails against the "dangers" of fish oil and omega-3 fatty acids. "I've recently learned that omega-3s are a double-edged sword...In some cases, omega-3s could be fatal."

He goes on to say that, while he believes that fish oil may prevent heart attacks, it has fatal effect if you already have heart disease.

Does this make sense to you?

He's basing his views on a single, obscure study published in 2003 conducted in rural England that showed an increase in death and heart attack on fish oil. Most authorities have not taken these findings seriously, since they are wildly contrary to all other observations and because the study had some design flaws.

Despite the fact that this isolated study runs counter to all other, better-conducted studies seems not to matter to Dr. Ornish.

Clinging to the low-fat concept is like hoping 8-track tapes will make a comeback. It's not going to happen. We enjoyed the benefits while they lasted, appropriate for the era. But now, they're woefully outdated.

The overwhelming evidence is that fish oil provides tremendous benefits with little or no downside. In the Track Your Plaque program, fish oil remains a crucial supplement to gain control over your coronary plaque and stop or reduce your heart scan score. Ignore the doomsday preachings of Dr. Ornish.

(Watch for an article I wrote updating the benefits of fish oil for Life Extension magazine.)

The cholesterol fallacy

Evan spotted the kiosk set up in the middle of the local mall. "Free cholesterol screenings. Know your heart health!" the sign declared.

It was a free cholesterol screening being offered by a local hospital.

The friendly nurse behind the kiosk had Evan fill out a form, then pricked his finger. Five minutes later, she reported to him with a smile, "Sir, your cholesterol is 177--your heart's fine! We get concerned when cholesterol is over 200. So you're in a safe range."

What the nurse failed to recognize is that Evan's HDL was 30 mg, a low value that actually places him at high risk for heart disease. Low HDL also signifies high likelihood of the small LDL particle pattern, a marked predisposition towards pre-diabetes and diabetes, a probable over-reliance on processed carbohydrates in his diet, a dramatically increased probability of hidden inflammation (e.g., elevated C-reactive protein), increased tendency for high blood pressure. . .

In other words, Evan's "favorable" total cholesterol is, in truth, nonsense. It's misleading, falsely reassuring, and provided none of the insight that a real effort might have yielded. Like hippies, tie-dye, other relics of the 1960s, total cholesterol needs to be put to rest. It has served many people poorly and been responsible for countless deaths.

When you see a kiosk or other service like this, even if it's free, run the other way.

"Heart disease a growth business"





So announced a Boston newspaper recently, featuring a story about new heart program at a local hospital.

They were announcing how a hospital had entered the cardiovasculare procedure game and how it would boost their bottom line. The article discussed how the hospital administration was anticipating "a surge in patients from the baby boom generation."

To justify this new program, the article quoted an administrator from another hospital: "Cardiovascular issues is [sic] the number one cause people sought treatment at our hospital."

The hospital featured in the story had spent $13.5 million dollars to develop their program.

Do you think they'll make it back?

You bet they will--many times over. Hospitals are businesses, complete with a bottom line, an expectation of profit and an eye towards growth.

The hospitals in the city where I live (Milwaukee, Wisconsin) are, as in Boston and elsewhere, very aggressive--expanding into new territories, hiring new "salesmen" (physicians), all to capture more marketshare and produce more "product" (your coronary angioplasty, stent, bypass surgery, defibrillator, etc.).

The equation for hospital profits is tried and true. Ignore your heart disese risk and you can help your local hospital grow its business. Neglect to get your heart scan and you can help your hospital pay down its debt. Get a heart scan, then do nothing about it, and you may even justify a pay raise for the hospital administrators for record revenue growth and profit.

Hospitals are a growth business because of the failure of most people and their doctors to 1) identify hidden coronary disease (CT heart scan to obtain your heart scan score), then 2) seize control over it (the Track Your Plaque program or, at least, your doctor's guidance along with your efforts at prevention).

Unless you do so, you are highly likely to help your hospital boost its annual goal for procedures.

Rerun: To let low-carb right, you must check POSTPRANDIAL blood sugars

Checking postprandial (after-eating) blood sugars yields extraordinary advantage in creating better diets for many people.

This idea has proven so powerful that I am running a previous Heart Scan Blog post on this practice to bring any newcomers up-to-date on this powerful way to improve diet, lose weight, reduce small LDL, reduce triglycerides, and reduce blood pressure.



To get low-carb right, you need to check blood sugars

Reducing your carbohydrate exposure, particularly to wheat, cornstarch, and sucrose (table sugar), helps with weight loss; reduction of triglycerides, small LDL, and c-reactive protein; increases HDL; reduces blood pressure. There should be no remaining doubt on these effects.

However, I am going to propose that you cannot truly get your low-carb diet right without checking blood sugars. Let me explain.

Carbohydrates are the dominant driver of blood sugar (glucose) after eating. But it's clear that we also obtain some wonderfully healthy nutrients from carbohydrate sources: Think anthocyanins from blueberries and pomegranates, vitamin C from citrus, and soluble fiber from beans. There are many good things in carbohydrate foods.

How do we weigh the need to reduce carbohydrates with their benefits?

Blood sugar after eating ("postprandial") is the best index of carbohydrate metabolism we have (not fasting blood sugar). It also provides an indirect gauge of small LDL. Checking your blood sugar (glucose) has become an easy and relatively inexpensive tool that just about anybody can incorporate into health habits. More often than not, it can also provide you with some unexpected insights about your response to diet.

If you’re not a diabetic, why bother checking blood sugar? New studies have documented the increased likelihood of cardiovascular events with increased postprandial blood sugars well below the ranges regarded as diabetic. A blood sugar level of 140 mg/dl after a meal carries 30-60% increased (relative) risk for heart attack and other events. The increase in risk begins at even lower levels, perhaps 110 mg/dl or lower after-eating.

We use a one-hour after eating blood sugar to gauge the effects of a meal. If, for instance, your dinner of baked chicken, asparagus brushed with olive oil, sauteed mushrooms, mashed potatoes, and a piece of Italian bread yields a one-hour blood sugar of 155 mg/dl, you know that something is wrong. (This is far more common than most people think.)

Doing this myself, I have been shocked at the times I've had an unexpectedly high blood sugar from seemingly "safe' foods, or when a store- or restaurant-bought meal had some concealed source of sugar or carbohydrate. (I recently had a restaurant meal of a turkey burger with cheese, mixed salad with balsamic vinegar dressing, along with a few bites of my wife's veggie omelet. Blood sugar one hour later: 127 mg/dl. I believe sugar added to the salad dressing was the culprit.)

You can now purchase your own blood glucose monitor at stores like Walmart and Walgreens for $10-20. You will also need to purchase the fingerstick lancets and test strips; the test strips are the most costly part of the picture, usually running $0.50 to $1.00 per test strip. But since people without diabetes check their blood sugar only occasionally, the cost of the test strips is, over time, modest. I've had several devices over the years, but my current favorite for ease-of-use is the LifeScan OneTouch UltraMini that cost me $18.99 at Walgreens.

Checking after-meal blood sugars is, in my view, a powerful means of managing diet when reducing carbohydrate exposure is your goal. It provides immediate feedback on the carbohydrate aspect of your diet, allowing you to adjust and tweak carbohydrate intake to your individual metabolism.

LDL glycation

The proteins of the body are subject to the process of glycation, modification of protein structures by glucose (blood sugar). In the last Heart Scan Blog post, I discussed how glycated hemoglobin, available as a common test called HbA1c, can serve as a reflection of protein glycation (though it does not indicate actual Advanced Glycation End-products, or AGEs, just a surrogate indicator).

There is one very important protein that is subject to glycation: Apoprotein B.

Apoprotein B, or Apo B, is the principal protein of VLDL and LDL particles. Because there is one Apo B molecule per VLDL or LDL particle, Apo B can serve as a virtual VLDL/LDL particle count. The higher the Apo B, the greater the number of VLDL and LDL particles.

Because Apo B is a protein, it too is subject to the process of glycation. The interesting thing about the glycation of Apo B is that its "glycatability" depends on LDL particle size: The smaller the LDL particle, the more glycation-prone the Apo B contained within.

Younis et al have documented an extraordinary variation in glycatability between large and small LDL, with small LDL showing an 8-fold increased potential.

Think about it: Carbohydrates in the diet, such as wheat products and sugars, trigger formation of small LDL particles. Small LDL particles are then more glycation-prone by up to a factor of 8. Interestingly, HbA1c is tightly correlated with glycation of Apo B. Diabetics with high HbA1c, in particular, have the greatest quantity of glycated Apo B. They are also the group most likely to develop coronary atherosclerosis, as well as other consequences of excessive AGEs.

No matter how you spin it, the story of carbohydrates is getting uglier and uglier. Carbohydrates, such as those in your whole grain bagel, drive small LDL up, while making them prone to a glycating process that makes them more likely to contribute to formation of coronary atherosclerotic plaque.

High HbA1c: You're getting older . . . faster

Over the years, we all accumulate Advanced Glycation End-products, or AGEs.

AGEs are part of aging; they are part of human disease. AGEs are the result of modification of proteins by glucose. AGEs form the basis for many disease conditions.

Accumulated AGEs have been associated with aging, dementia, cataracts, osteoporosis, deafness, cancer, and atherosclerosis. Most of the complications of diabetes have been attributable to AGEs.

There's one readily available method to assess your recent AGE status: HbA1c.

Hemoglobin is the oxygen-carrying protein of red blood cells. Like other proteins, hemoglobin becomes glycated in the presence of glucose. Hemoglobin glycation increases linearly with glucose: The higher the serum or tissue glucose level, the more glycation of hemoglobin develops. Glycated hemoglobin is available as the common test, HbA1c.

Ideal HbA1c is 4.5% or less, i.e., 4.5% of hemoglobin molecules are glycated. Diabetics typically have HbA1c 7.0% or greater, not uncommonly greater than 10%.

In other words, repetitive and sustained high blood glucose leads to greater hemoglobin glycation, higher HbA1c, and indicates greater glycation of proteins in nerve cells, the lens of your eye, proteins lining arteries, and apoprotein B in LDL cholesterol particles.

If AGEs accumulate as a sign of aging, and high blood sugars lead to greater degrees of glycation, it only follows that higher HbA1c marks a tendency for accelerated aging and disease.

Indeed, that is what plays out in real life. People with diabetes, for instance, have kidney failure, heart disease, stroke, cataracts, etc. at a much higher rate than people without diabetes. People with pre-diabetes likewise.

The higher your HbA1c, the greater the degree of glycation of other proteins beyond hemoglobin, the faster you are aging and subject to all the phenomena that accompany aging. So that blood glucose of 175 mg/dl you experience after oatmeal is not a good idea. 

The lesson: Keep HbA1c really low. First, slash carbohydrates, the only foods that substantially increase blood glucose. Second, maintain ideal weight, since normal insulin responsiveness requires normal body weight. Third, stay physically active, since exercise and physical activity exerts a powerful glucose-reducing effect. Fourth, consider use of glucose-reducing supplements, an issue for another day.

While HbA1c cannot indicate cumulative AGE status, it can reflect your recent (preceding 60 to 90 days) exposure to this age-accelerating thing called glucose.

If your doctor refuses to accommodate your request for a HbA1c test, you can perform your own fingerstick test.

Slash carbs . . . What happens?

Cut the carbohydrates in your diet and what sorts of results can you expect?

Carbohydrate reduction results in:

Reduced small LDL--This effect is profound. Carbohydrates increase small LDL; reduction of carbohydrates reduce small LDL. People are often confused by this because the effect will not be evident in the crude, calculated (Friedewald) LDL that your doctor provides.

Increased HDL--The HDL-increasing effect of carbohydrate reduction may require 1-2 years. In fact, in the first 2 months, HDL will drop, only to be followed by a slow, gradual increase. This is the reason why, in a number of low-carb diet studies, HDL was shown to be reduced.--Had the timeline been longer, HDL would show a significant increase.

Decreased triglycerides--Like reduction of small LDL, the effect is substantial. Triglyceride reductions of several hundred milligrams are not at all uncommon. In people with familial hypertriglyceridemia with triglyceride levels in the thousands of milligrams per deciliter, triglyceride levels will plummet with carbohydrate restriction. (Ironically, conventional treatment for familial hypertriglyceridemia is fat restriction, a practice that can reduce triglycerides modestly in these people, but not anywhere near as effectively as carbohydrate restriction.) Triglyceride reduction is crucial, because triglycerides are required by the process to make small LDL--less triglycerides, less small LDL.

Decreased inflammation--This will be reflected in the crude surface marker, c-reactive protein--Yes, the test that the drug industry has tried to convince you to take statins drugs to reduce. In my view, it is an absurd notion that you need to take a drug like Crestor to reduce risk associated with increased CRP. If you want to reduce CRP to the floor, eliminate wheat and other junk carbohydrates. (You should also add vitamin D, another potent CRP-reducing strategy.)

Reduced blood pressure--Like HDL, blood pressure will respond over an extended period of months to years, not days or weeks. The blood pressure reduction will be proportion to the amount of reduction in your "wheat belly."

Reduced blood sugar--Whether you watch fasting blood sugar, postprandial (after-meal) blood sugars, or HbA1c, you will witness dramatic reductions by eliminating or reducing the foods that generate the high blood sugar responses in the first place. Diabetics, in particular, will see the biggest reductions, despite the fact that the American Diabetes Association persists in advising diabetics to eat all the carbohydrates they want. Reductions in postprandial (after-eating) blood sugars, in particular, will reduce the process of LDL glycation, the modification of LDL particles by glucose that makes them more plaque-causing.


You may notice that the above list corresponds to the list of common plagues targeted by the pharmaceutical industry: blood pressure, diabetes (diabetes being the growth industry of the 21st century), high cholesterol. In other words, high-carbohydrate, low-fat foods from the food industry create the list of problems; the pharmaceutical industry steps in to treat the consequences.

In the Track Your Plaque approach, we focus specifically on elimination of wheat, cornstarch, and sugars, the most offensive among the carbohydrates. The need to avoid other carbohydrates, e.g., barley, oats, quinoa, spelt, etc., depends on individual carbohydrate sensitivty, though I tend to suggest minimal exposure.

Normal fasting glucose with high HbA1c

Jonathan's fasting glucose: 85 mg/dl
His HbA1c: 6.7%

Jonathan's high HbA1c reflects blood glucose fluctuations over the preceding 60-90 days and can be used to calculate an estimated average glucose (eAG) with the following equation:

eAG = 28.7 X A1c – 46.7

(For glucose in mmol/L, the equation is eAG = 1.59 × A1C - 2.59)

Jonathan's HbA1c therefore equates to an eAG of 145.59 mg/dl--yet his fasting glucose value is 85 mg/dl. 

This is a common situation: Normal fasting glucose, high HbA1c. It comes from high postprandial glucose values, high values after meals. 

It suggests that, despite having normal glucose while fasting, Jonathan experiences high postprandial glucose values after many or most of his meals. After a breakfast of oatmeal, for instance, he likely has a blood glucose of 150 mg/dl or greater. After breakfast cereal, blood glucose likely exceeds 180 mg/dl. With two slices of whole wheat bread, glucose likewise likely runs 150-180 mg/dl. 

The best measure of all is a postprandial glucose one hour after the completion of a meal, a measure you can easily obtain yourself with a home glucose meter. Second best: fasting glucose with HbA1c.

Gain control over this phenomenon and you 1) reduce fasting blood sugar, 2) reduce expression of small LDL particles, and 3) lose weight.  

Can you handle fat?

No question: Low-carbohydrate diets generate improved postprandial lipoprotein responses.

Here's a graph from one of Jeff Volek's great studies:



Participants followed a low-carb diet of less than 50 g per day carbohydrate ("ketogenic") with 61% fat.   The curves were generated by administering a 123 g fat challenge with triglyceride levels assessed postprandially. The solid line represents the postprandial response at the start; dotted line after the 6-week low-carb effort.

Note that:

1) The postprandial triglyceride (area-under-the-curve) response was reduced by 29% in the low-carb diet.  That's a good thing.

2) The large fat challenge generated high triglycerides of greater than 160 mg/dl even in the low-carb group. That's a bad thing. 

In other words, low-carb improves postprandial responses substantially--but postprandial phenomena still occur. Postprandial triglycerides of 88 mg/dl or greater are associated with greater heart attack risk because they signify the presence of greater quantities of atherogenic (plaque-causing) postprandial lipoproteins.

A full discussion of these phenomena can be found in the Track Your Plaque Special Report, Postprandial Responses: The Storm After the Quiet!, part of a 3-part series on postprandial phenomena.

Statin stupid

If we followed the lead of the pharmaceutical industry and my cardiology colleagues, we would all subscribe to the "statins for all" philosophy. There is now $2 billion of clinical "research" to back up this "evidence-based" practice.

I do not endorse this "statins for all" philosophy. I believe it is a product of the raw profiteering of the pharmaceutical industry, who are adept at recruiting physicians to their cause.

But lost in the confusion of tainted studies and over-the-top media saturation is the fact that there are small groups of people who likely do obtain benefit from statin drugs. They would certainly benefit from better informed scrutiny of their lipoprotein and metabolic abnormalities. But treatment may involve statins.

This is entirely distinct from the "statins for all" argument, the simpleminded rule that primary care physicians and cardiologist are told to follow.

Groups who may indeed benefit from statin therapy include:

Homozygous or heterozygous familial hypercholesterolemia--Lacking a receptor for LDL particles, LDL piles up to very high levels in these people. LDLs of 300+ are common and lead to heart disease and stroke at relatively young ages.

Combined mixed hyperlipidemia--Among the one or more genetic defects underlying this condition involves excessive production of apoprotein B and VLDL particles. This leads to high risk for heart disease.

People unable to follow a diet to correct their lipid disorder--I have 80+-year old patients, for instance, who say, "I've eaten this way for 82 years. I'm not going to change now!" In the absence of diet and other efforts (e.g., omega-3 fatty acids from fish oil), drugs may be the answer.

In other words, of the $27 billion annual bill for statin drugs, perhaps a tiny fraction is truly necessary. The majority of people taking statin drugs would not really need them if they had the real answers. But don't let that confuse us: There are some people who do indeed benefit.

Butter and insulin

In a previous post, Atkins Diet: Common Errors, I commented on butter's unusual ability to provoke insulin responses. I offer this as a possible reason why, after a period of effective weight loss on a low-carbohydrate program, inclusion of some foods, such as butter, will trigger weight gain or stall weight loss efforts.

This develops because of butter's insulin-triggering effect, doubling or tripling insulin responses (postprandial area-under-the-curve). If insulin is triggered, fat gain follows.

Here's one such study documenting this effect: Distinctive postprandial modulation of ß cell function and insulin sensitivity by dietary fats: monounsaturated compared with saturated fatty acids

López et al 2008


From Lopez et al 2008. Mean (± SD) plasma glucose, insulin, triglyceride, and free fatty acid (FFA) concentrations during glucose and triglyceride tolerance test meal (GTTTM) with no fat (control), enriched in monounsaturated fatty acids (MUFAs) from refined olive oil (ROO meal), with added butter, with a mixture of vegetable and fish oils (VEFO) or with high-palmitic sunflower oil (HPSO). N = 14.

The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

Fat, in general, does not make you fat. But butter makes you fat.

Vitamin D as a cardiovascular risk factor gains ground

If you were reading The Heart Scan Blog back in 2007, or read my Life Extension article on vitamin D deficiency as a cardiovascular risk factor, you already knew that vitamin D deficiency is rampant and adds to cardiovascular risk.

Results of a study from the Intermountain Medical Center Heart Institute in Utah bolster the concept that vitamin D deficiency is a cardiovascular risk factor, vitamin D normalization/supplementation reduces cardiovascular risk.

Science Daily reported:

For the first study, researchers followed two groups of patients for an average of one year each. In the first study group, over 9,400 patients, mostly female, reported low initial vitamin D levels, and had at least one follow up exam during that time period. Researchers found that 47 percent of the patients who increased their levels of vitamin D between the two visits showed a reduced risk for cardiovascular disease.


In the second study, researchers placed over 31,000 patients into three categories based on their levels of vitamin D. The patients in each category who increased their vitamin D levels to 43 nanograms per milliliter of blood or higher had lower rates of death, diabetes, cardiovascular disease, myocardial infarction, heart failure, high blood pressure, depression, and kidney failure. Currently, a level of 30 nanograms per milliliter is considered "normal."


Over the past 4 years, people in our program have been enjoying the extravagant benefits of vitamin D restoration. Cardiovascular benefits are becoming better documented and the bone health, cancer-preventing, insulin-normalizing, mood-adjusting, and anti-inflammatory effects likewise.

Atkins Diet: Common errors

No doubt: The diet approach advocated by the late Dr. Robert Atkins was a heck of a lot closer to an ideal diet than the knuckleheaded advice emitting from the USDA, American Heart Association, American Diabetes Association, and the Surgeon General's office.

But having just spent a week with Atkins low-carbers, here are some common errors that I see many make, errors that I believe have long-term health consequences, including impairment of weight loss.

Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods.

Consumption of cured meats--Cured, processed meats, such as sausage, hot dogs, salami, bologna, and bacon, have a color fixative called sodium nitrite, an additive that has been confidently linked to gastrointestinal cancers. Risk is likely dose-dependent: The more you ingest, the greater the long-term risk.

Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

Too many calories--While I agree that "a calorie is a calorie" and "calories in, calories out" are faulty concepts, I have anecdotally observed that long-time low-carbers often trend towards unlimited consumption of food, a phenomenon that seems to result in weight gain, especially in the sedentary. I wonder if this is a reflection of the insulinotropic action of dairy products and other proteins, compounded by the poor insulin responsiveness that develops with lack of physical activity. Factor into this conversation that lower calorie intake extends life, probably substantially (Sirt-2 activation and related phenomena, a la resveratrol). If lower calorie intake extends life, unlimited calorie intake likely shortens life.

Please don't hear this as low-carb bashing--it is not. It is a call to improve diets and not stumble into common traps that can impair heart health, weight loss, and longevity.
