An exercise in optimism

Followers of the Track Your Plaque program already know that maintaining an optimistic viewpoint is important in gaining control over coronary plaque.

In fact, I believe that, in many cases, a sense of optimism may make or break your CT heart scan score-reducing efforts. Pessimists rarely drop their score, while optimists do so all the time.

This week posed a challenge to my optimism. I spent the last week on jury duty hearing the details of a murder case. For four days, I listened to blow-by-blow testimony about the totally pointless, unprovoked death of a young man by a drug-dealing thug. Much of the witness testimony was from people who shared the hopeless, violent world of the defendant.

I was, however, completely impressed by the dedication of the prosecuting attorney, a 50-some year old man who was clearly deeply dedicated to his mission and didn't once provide any indication that he was grandstanding or looking for some personal glory. He was doing his job and trying to obtain justice for the fallen victim. I was equally impressed by the judge, who seemed unfazed by the events but carefully explained why the system worked the way it did. After the trial, he provided some further insights to us jury members and I saw him as a human being who, like the prosecutor, was trying to make a small contribution to making the world better.

Though many of the witnesses who testified against the defendant shared his world, I was impressed with their courage in coming forward. They face the threat of reprisals, I'm sure, for coming forward to the law and testifying against a known career criminal. Several of them said that they were not after any reward, but simply wished to do the right thing and provide testimony that proved damning against the defendant.

I acted as the jury foreman and I was proud of how the jury members listened carefully, asked intelligent and probing questions, and then helped us render a confident and expeditious sentence: guilty.

If anything, despite the tragic circumstances, I was much heartened at how all the participants in this process played their part and justice (at least in the legal sense) was served.

Let optimism prevail, even in dire circumstances.

No need to re-invent the wheel

I seem to be repeating myself lately, but I think this does bear repeating:

There's no need to re-invent the wheel when it comes to gaining control over your heart scan score.

The Track Your Plaque program is the most powerful approach known to help you gain control over your coronary atherosclerotic plaque and CT heart scan score, bar none. While 100% of people do not drop their score, more and more people every week are doing so. (One of the admitted weaknesses of the Track Your Plaque website is our failure to list more success stories; we're working on it.)

The basic program is quite simple:

--The Rule of 60 for lipids (LDL 60 mg/dl; HDL 60 mg/dl or greater; triglycerides 60 mg/dl or less)

--Identify hidden causes of plaque, esp. small LDL, Lp(a), and IDL, followed by specific corrective action

--Fish oil--minimum 1200 mg per day of EPA + DHA

--Normal vitamin D3 blood levels (We aim for 25-OH-vitamin D3 of 50-60 ng/ml)

--Normal blood sugar (<100 mg/dl)

--Normal blood pressure (<130/80)

--An optimistic attitude



Much of the other stuff--vitamin K, matrix metalloproteinase reducing strategies, flavonoid strategies, exercise-induced hypertension, etc.--are, for the majority, fluff. Their real role is in people who may have failed in stopping the rise of their heart scan score just doing the basics of the program.

If you neglect the basics, hoping to find some magic potion, I'm afraid the overwhelming likelihood is that you will fail. I've seen it happen time and again. Someone will come to my office with an extraordinary list of supplements--hawthorne, dozens of anti-oxidants, EDTA, concentrated flavonoid preparations, and on and on. Not only is it shockingly expensive to do this, it's also unnecessary and foolhardy. This kind of unfocused, hocus-pocus in the hopes of getting it right fail time after time.

The Track Your Plaque program, while not foolproof, is the best I know of. Stick to the basics and wander off when the basics fail. But there's extraordinary power in just achieving the basics.

Are we a front for drug companies?

I was shocked recently when someone accused me and the Track Your Plaque website of being nothing more than a front for the drug industry, that we are promoting concepts with the hidden pharmacuetical agenda behind us.

Don't make me laugh. How in the world that kind of impression could be gotten from either the Heart Scan Blog or the Track Your Plaque website is beyond me.

But I occasionally do need to state explicity: We do not promote drugs, neither this Blog nor the Track Your Plaque website has ever sought nor been backed by pharmaceutical money. The only money that supports this website is our own and that from paying Track Your Plaque members.

In fact, I am quite proud of the unbiased content and commentary on both venues. I challenge anyone to point out how and where there is any suggested relationship to a hidden source of commercial backing. I assure you, there is none.

If I say a drug is worth you and your doctor considering, then I say so with a true belief in it, not because somebody or some company paid me to say so. If I say a drug stinks, I believe that too. If we use a specific supplement in the program, it's because we believe it truly adds value to a plaque-reversal program. We receive no money from drug, supplement, or other commercial interests to promote their products. Period.

What is "normal"?

When it comes to laboratory values and medical testing, a common dilemma is knowing what is "normal." Let me explain.

First of all, when you receive a laboratory result for a test, a "reference range" or "normal range" is usually provided. Where did that range come from?

It varies from test to test. For instance, a low potassium is easy, because low potassium levels can lead to life threatening consequences, e.g., dangerous heart rhythms. High potassium likewise, because dangerous phenomena develop when potassium generally exceeds 5.5 mg/dl or so.

But what about something like HDL or LDL. Here's where confusion reigns. Often, "normal" is obtained by taking the average and saying that any value plus or minus two standard deviations (remember that painful class?) represents normal or reference range.

If that were true, what if we applied that principle to body weight. If we weighed several thousand adult women, the average would be in the neighborhood of 172 lbs (no kidding). Does that mean that 172 lbs plus or minus two standard deviations is normal? No, of course not.

There is therefore a distinction between "normal" and "desirable". For HDL cholesterol, your laboratory report might say that an HDL cholesterol of 40-60 mg/dl is normal. But is it desirable? I don't think so. The most frequent HDL level for a male with a heart attack is 42 mg/dl--hardly desirable.

Let's take triglycerides. The average triglyceride level in the U.S. is somewhere around 140 mg/dl. For those of us who do a lot of lipoprotein testing, we can tell you that triglycerides at this level, though generally regarded as being within the normal range, are associated with flagrant and obvious excesses of several abnormal lipoprotein particles that contribute to coronary plaque growth (VLDL and often IDL; small LDL; drop in HDL and shift towards small HDL).

So, always take the so-called "normal" or "reference" values on a lab report as crude guidelines that often have little or nothing to do with health or desirability. Unfortunately, many physicians are not aware of this and will declare any value within the normal or reference range as okay. An HDL of 40 mg is not okay. A triglyceride level of 140 mg is also not okay.

What is okay? What is desirable? That depends on the parameter being examined. From a basic lipid standpoint, of course, we regard desirable as 60-60-60. Desirability from a lipoprotein standpoint we will cover in a more thorough Track Your Plaque Special Report in future.

The wisdom of the masses

My sister sent me these quotes:



"We don't like their sound, and guitar music is on the way out."

Decca Recording Co. rejecting the Beatles, 1962


"Stocks have reached what looks like a permanently high plateau."

Irving Fisher, Professor of Economics, Yale University, 1929


"Airplanes are interesting toys but of no military value."

Marechal Ferdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, France


"Everything that can be invented has been invented."

Charles H. Duell, Commissioner, US Office of Patents, 1899



No doubt, conventional wisdom can often be laughably (tragically?) wrong. The problem is that, as absurd as all the above sentiments seem to us now and in retrospect, they represented the view of many people years ago. These views were held by many, including many people in positions of power and decision-making responsibility.

A more relevant but nonetheless laughable and widely held belief in 2007: coronary heart disease should be treated with hospital procedures.

Why is a disease that requires 30 years to develop treated only at the final moments with a procedure? Do you only change your car's oil when the engine is on its last legs? Or, do periodic, relatively effortless oil changes during the life of the car make better sense?

I witness just how brainwashed the public has become with this crazed notion when I meet someone socially at, say a fundraiser or cocktail party. When they ask what I do, I tell them I'm a cardiologist. The invariable response: "Oh, what hospital do you work out of?"

I tell them I don't, that I take care of the majority of heart disease right from the office. 99% of the time I get a puzzled look. If we had comic bubbles above our heads revealing our internal thoughts, it would read "Yeah, right. What a kook."

The notion that coronary heart disease is something that is manageable with simple tools for the majority of us in the early stages is entirely foreign to almost everybody. The hospitals and the medical industry have so succeeded in dazzling the public with images of staff in scrubs, rushing from emergency to emergency, lights flashing, scalpels flying. . . how can you possibly accomplish this at home or anywhere outside of the high-tech world of the hospital?

Well, I'm a cardiologist and I do it every day. We all need a figurative dose of electroshock therapy to shake ourselves of this crazy notion.

How important is l-arginine?

Perhaps more than any other supplement, l-arginine causes frustration and confusion. It’s difficult to find, sometimes quite expensive, and some preparations cause loose stools.

Just how necessary is it?

L-arginine, you’ll recall, is a source of nitric oxide, or NO. Though it’s the same stuff as in car exhaust, NO provides a critical signaling role in your body’s cells that regulate a multitude of functions. Among the important roles of NO is to powerfully dilate, or relax, arteries. A constant flow of NO is required for health, particularly since each molecule persists only a few seconds.

L-arginine is the body’s source of nitric oxide. In addition, a peculiar but very effective blocker of l-arginine called asymmetric dimethylarginine, or ASDM, has recently been discovered to prevent the production of NO. Varied conditions like hypertension, diabetes, high cholesterol, excessive saturated fat or processed carbohydrate intake all lead to heightened levels of ASDM, often several-fold greater levels, and thereby effectively blocking NO production.

The “Arginine Paradox” is the name that some researchers in this field have given to the unusual property of l-arginine supplementation to “overpower” the blocking effects of ASDM. This is somewhat unusual in biologic systems in that an agent that blocks a receptor cannot usually be outmuscled by providing excess material for a reaction. Kind of like hoping that your car runs faster simply by topping up the gas tank.

Concrete observable benefits have been made for l-arginine in clinical trials, such as arterial relaxation that results in arterial enlargement (which can actually be seen in the cath lab); anti-inflammatory effects; reduction of blood pressure; enhancement of insulin responses, etc. All of these effects can be connected to beneficial properties that may facilitate atherosclerotic plaque regression and, indeed, there are limited data to document that this is true.

Drug companies may be greedy, but they’re not stupid. They’ve been vigorously pursuing this line of research for some years, a research path that led inadvertently to the erectile dysfunction agent, sildenafil (Viagra), and all its subsequent competitors. (Erectile dysfunction is another expression of endothelial dysfunction, since male erections are driven by the ability to dilate penile arteries.) The wonderful properties of NO enhancement continue to occupy research labs around the world.

Wow. So what’s the reluctance? In the early years of the Track Your Plaque program (meaning just a short 7-8 years ago), I was thoroughly convinced that l-arginine was a crucial, necessary part of a plaque regression program. Without it, you would rarely succeed. With it, the odds were tipped in your favor.

However, something curious has emerged recently. I’ve seen more and more people dropping their heart scan scores. Not just a little bit, but a huge amount. Witness our most recent record holder, Neal, who dropped his score 51% in 15 months. Just five years ago, this magnitude of reversal was unimaginable. Granted, Neal is our record holder, but others are obtaining 10, 18, 24, 30% drops in scores all the time. Many have done it without l-arginine.

Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score.

My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time.

There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden.

Track Your Plaque and non-commercialism

If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site.

We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent.

That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products.

Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info?

Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage.

I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation.

I'd welcome any feedback either through this Blog or through the contact@cureality.com.

The nattokinase scam

A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase.

The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification.

Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts.

Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase.

Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."

Don't you believe it. This is patent nonsense. There are several problems with this rationale:

--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right.

--Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them.

The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?

Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.

Blood pressure with exercise

Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.

Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.

We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.

Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)

I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).

Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.

Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.

The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.

Vitamin D2 vs. vitamin D3

An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.

Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.

The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.

However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.

Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.

D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness.

25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.
American Heart Association diet makes a monkey out of you

American Heart Association diet makes a monkey out of you

Heart Scan Blog reader, Roger, brought this New York Times article to my attention.

In an effort to develop a better experimental model for obesity than mice, scientists have turned to monkeys and other primates. The emerging observations are eerily reminiscent of what you and I witness just by going to the local grocery store or fast food outlet:

"'It wasn’t until we added those carbs that we got all those other changes, including those changes in body fat,' said Anthony G. Comuzzie, who helped create an obese baboon colony at the Southwest National Primate Research Center in San Antonio."

"Fat Albert, one of her monkeys who she said was at one time the world’s heaviest rhesus, at 70 pounds, ate “nothing but American Heart Association-recommended diet,” she said."

Yes, indeed: The American Heart Association diet makes monkeys fat. Extrapolate this a little higher on the evolutionary ladder and guess what?

This is one of the many reasons why, when I have a patient who is counseled by the hospital dietitian on the American Heart Association diet, I advise them to 1) ignore everything the dietitian told them, and then 2) follow the wheat-free, cornstarch-free, sugar-free, whole food diet I advocate.

Not unexpectedly, much of this primate research is not being devoted to just manipulating diet to achieve weight loss and health, but to develop new drugs to "treat" obesity.

Would you like a banana?

    Back in 2004 I was seeing a Cardiologist because of AFib (since "cured" by an ablation).  The good Doctor wanted to put me on a Statin for reasons having to do with unexplained multiple "risk factors". Not being a big fan of legal drugs, I asked if I could try diet first. He said, "Sure, you can try the American Heart Association diet but...it never works".  Undaunted I tried it anyway and sure enough 3 months later I had gained 15 lbs and my LDL was even higher (I couldn't stop eating).  BTW, I quit the Statin 2 years ago and have been Paleo since. - Jay

    I think you are taking the article completely out of context. The monkeys were on the American Heart Association diet and then they added in high frutcose corn syrup. The monkeys got fatter because of the carbs from the corn syrup, not from the AHA diet. Personally I am paleo, but you are pulling a Glenn Beck here.

    The point is not whether HFCS or wheat was the cause, but rather that all simple and refined carbohydrates will create the pot belly that Shiva and most of Americans have.  The animal cruelty police should spend their efforts in Washington protesting the plethora of garbage advice that is forced on us by organizations like the AHA and cut their funding.  By doing so, it will have a significant positive impact and help reverse the upward trends of obesity, diabetes and heart disease that your tax dollars go to perpetuate.  The AHA is one of the most corrupt and lobbied groups by special interests agriculture, the same folks who bring you the refined carbs.  Once the agriculture industry checks clear in the AHA bank account, the AHA "heart Healthy" seal of approval is on the box.  If you bother to look most of the AHA "Heart Healthy" cereals have refined cereals grains and high fructose corn syrup.

    @Anonymous #2, the group on the HFCS drinks (among other things) and the group on the AHA diet were two different groups of monkeys:

    "Dr. Grove [of Oregon Health and Science University] and researchers at some other centers say the high-fructose corn syrup appears to accelerate the development of obesity and diabetes....

    “'It wasn’t until we added those carbs that we got all those other changes, including those changes in body fat', said Anthony G. Comuzzie, who helped create an obese baboon colony at the Southwest National Primate Research Center in San Antonio.

    "Still, about 40 percent do not put on a lot of weight.

    "Barbara C. Hansen of the University of South Florida said calories, but not high fat, were important. 'To suggest that humans and monkeys get fat because of a high-fat diet is not a good suggestion', she said.

    "Dr. Hansen, who has been doing research on obese monkeys for four decades, prefers animals that become naturally obese with age, just as many humans do. Fat Albert, one of her monkeys who she said was at one time the world’s heaviest rhesus, at 70 pounds, ate 'nothing but an American Heart Association-recommended diet', she said."

    The article goes on to refer to the first diet as "high fat," even though it's only 33% fat, and the way the article is written, it's hard to tell the groups apart.

    Take the banana; a banana a day for one year offers hormetic (small bit of bad does good) low dose radiation of +/- 3.6 milli-rems for the entire year. Low dose radiation boosts the cytokine activity of NK (Natural Killer), the tumor stopper. A chest x-ray doses out 10 milli-rems by comparison.

    Potassium Kiss, found in bannanas, is 0.0118% K40 isotope potassium. It emits mostly gamma radiation (when proton snags an extra electron) and some beta particles (when neutron mass spins off an electron and neutron becomes a proton); which are "slow" in collision with things, like a cell.

    To a recent "Anonymous":

    Dr Davis does have have an obligation to his readers. By convention, he is expected to explain himself and respond to polite and appropriate questions regarding his blog. That is why the interaction is provided, and he seems usually to encourage the dialogue. Dr Davis could have just as easily established this blog without the interactive feature. Currently, among usual glowing reader comments and often enlightening questions has come some criticism. His response to this criticism is what is currently lacking ... of course, this is only my opinion.

    By the way, I am not exactly sure what "entitled anonymous douchebags" have to do with anything.

    Fortunately, commentary on this excellent blog is for the most part constructive and informative. However a comment like this is frankly annoying because it’s mean-spirited, disingenuous, cowardly, and clearly not helpful. The poster is not obliged to read this blog, let alone dump on it like this anonymously!

    Interesting!  I have been advising a woman who works in a chimpanzee sanctuary in the North West.  There is one chimp who had blood sugars of 1000.  

    Sadly, they have put this chimp on Crystal Light and Tofu as a remedy.  

    Chimps share 99% DNA with humans.  We know that aspartame and soy are both dangerous to the human body.  

    The most interesting thing is, she rebelled when her goodies were taken away.  

    They too are addicts just like us.

    You're the only doctor I trust. The more i see the changes in my BP and overall health following your advice, plus the more I learn about what should first be done to treat hypertension, the more pissed off I get.
    What jerk puts a young woman on atenolol without even asking for some tests or if she eats too much salt or if she's wound high at the dr's office!!?? What the hell!?

    BTW, my blood pressure has dropped even more- an average of around 121/81- from 151/102. This is with 12mg of atenolol which I should hopefully kick to the curb soon Smile

    Hi Misty,
    Although chimps and humans share 96% identical proteins the implication of our intervention is complicated. Here's why.

    We actually have 40 million genome variables, including 500
    DNA repair/apoptosis pathway proteins. 5% of proteins show different splice variations; we have different arrangements of coding regions on the chromosomes we share.

    Chimps have 2.5 splice variations in places where humans only 1.5 gene splicing possibilities. 80 proteins we share similar gene intron segments for the chimp's intron is longer. Humans have more genetic activity post-translation to further modify events.

    Humans don't have Neu5Gc (N-glycolyl-neuraminic acid) which is a sialic acid binding immuno-
    globulin-like lectin (Siglec). This mediates molecules of sialic acid to perform differently. It directs what gets bound; the result is spleen macrophage response for chimps immune system works differently.

    The chimp ligand (thing that binds to something) processing mechanism extends to how they metabolize estrogen and phyto-estrogen iso-flavenoids (like soybeans contain). They pass both ligands, like wheat lectins, and estrogens more fully in their urine than humans do.

    For chimps a high fat diet causes less urinary excretion of estrogen, as well as less of the fragments of peptides from lectin ligands. To be precise high protein and high carbohydrate diets also diminish those metabolites % in chimp urine; just less so than high fat.

    Dr Davis,

    I have just found your blog because I have only recently begun searching for dietary info in order to guide me in rebuilding my skeletal muscle (and brain) after a so-far-11-month bout of severe adverse effects to a statin.  (When prescribed my readings were: Total Chol 297, HDL 117, LDL 165, triglycerides 73 – after 2 months of little exercise as the result of pneumonia and eye surgery.)

    The widespread acceptance of the "Paleo" diet interested me greatly, because I independently came to some of the same conclusions several years ago.  There is, however, a big Something that I don't understand and that I haven't seen addressed.  I hope you can – briefly, I know – educate me.  Why such severe restrictions on carbs when they were so important in our survival?

    The characterization of Paleo as high protein, high fat, low low carbs doesn't square with my college science courses and subsequent reading.  Early, early man would have grubbed around for whatever he could find, and, yes grubs would have been eaten were he lucky enough to find them, as well as other insects, wounded  small game, carrion, and fruit/berries/nuts.  Early man would also have discovered ROOTS and TUBERS very early on, and wild pea pods and the like, long, LONG before he was capable of running down game alone or in concert, or could even be sure of modest, reliable supplies of protein and fat.

    And once he was a hunter, then what?  Not much fat on wild monkeys and stressed hooved animals (lots of other predators were after them, too), and one had to live between those perhaps widely spaced hunts that were successful and had to be shared.  More ROOTS and TUBERS – because fruit alone tends to leave you hungry for more (the fructose), whereas a nice raw potato, a few carrots, could calm the gnawing in the stomach.

    Yes, I see that we now need considerable protein and a lot of fat (compared to current guidelines) because as we progressed  our expanded diet of increased amounts of protein and fat permitted our brains, especially, and our bodies to evolve to take advantage of such nutrients.  But I can't agree with the demonization of a large segment of our natural food supply.  Cut out grains.  I can see that.  But the sweet potato?  In the skin?  With generous amounts of butter gilding its fiber-rich goodness?

    Why?

    This may clarify, in their recent 2010 paper, M Konner and SB Eaton, estimate the ancestral diet (as % of daily energy) composed of
       35-40 acrbohydate,
       25-30 protein, and
       20-35 fat.
    They comment that the carbohydrate source for “hunter-gatherers” (HG) was from fruit, vegetables, and nuts, not from grains. They go on to say that the reduction of carbohydrates to extremely low levels is not consistent with the HG model, but neither is a high-carbohydrate, “meat as a condiment” type of diet.

    Konner and Eaton, both physicians, published their seminal paper on Paleolithic nutrition in 1985. The statistic above comes from their most recent paper of 2010. For those interested in how the popular interpretation of scientific research tends to “spin” the original detail, references to both their papers are below. Unfortunately, the 1985 article in the New England Journal of Medicine is restricted to paid subscribers only, while the recent invited article in Nutrition in Clinical Practice is available free online.

    There seem to be a few anonymous people making posts giving their opinion about how this blog should be run. Some of their assertions remind me of the entitlement mentality ruining this country.

    First, Dr. Davis is under no obligation to answer anyone's comments or questions.  How much do you pay to come here and read? I thought so.

    Second, when he chooses to respond, understand it is taking time out of his day that could go to his medical practice, (Real clients who pay for his services) his family, or without knowing the man personally, his hobbies or other interests.  How much time do you think it would take to write an answer to each person who poses a question in the response section on this blog?  Keep in mind how much slower writing is than speaking! It would take hours.

    Maybe it hasn't occurred to some of you that an answer to one person in the comments section won't be seen by very many people.  A much better use of his time is to write a short blog post at some time in the future that will be seen by many, and will be search-able, rather than answering the same question over and over again in the comments section.

    It's not all about you, people. Get a life.

    Worldinside, first, there's no one paleo diet. At certain times and places, like Cro-magnon Europe, the diet was nearly all meat. Paleolithic humans ate animals (snout to tail, not just muscle meat), fruit (in season), and, yes, tubers when they were available.

    Second, probably unlike Paleolithic humans, many readers of this blog don't have normal blood glucose reactions to carbohydrates. As you probably know, carbohydrate consumption spikes blood sugar even in normal, healthy people. In people with diabetes or metabolic syndrome, eating a tuber can cause BG levels that can lead to organ and tissue damage. Overconsumption of carbs over a month in such people can lead to high triglycerides as well--not to mention weight gain.

    While it's useful to look at how Paleolithic humans ate, we also need to look at medical science and keep our own individual quirks in mind. Humans need to eat protein. We also need to eat fat; we can't make essential fatty acids ourselves, and dietary fats have a unique ability to allow us to absorb vitamins A, D, E, and K. But there's no such thing as an essential carbohydrate (people who have hypoglycemia aside). Our liver can make blood glucose from protein. And just because something is natural and somebody else can eat loads of it, doesn't mean everybody can eat it.

    Assuming your goal is longevity and health in old age, it doesn't matter what our hunter-gatherer ancestors ate, because they didn't live much beyond age 70, which is quite young by modern standards. Living to 100 and being healthy in your 90's is very unnatural, so it follows that those of us who want to live that long should eat unnaturally. All the evidence I've see suggests that being lean and conditioned is the way to go, regardless of diet, but that a mostly vegetables diet is most conducive to longevity. Eating mostly grains is also okay. Eating high-fat or high-meat is NOT conducive to longevity.

    If you are not lean and conditioned, then first priority is to become lean and conditioned, and any diet which helps towards this primary goal is a good diet. Only after you become lean and conditioned do you really need to start worrying about diet.

    … as always such enlightening comments …

    In my neighborhood, it is generally accepted that the life expectancy at birth for preindustrial populations was 30-35 years. This was due not to the absence of older people but due to the extremely high infant and child mortality. Deaths overwhelmingly were due to infectious diseases that are now under control, more or less. With the longer average life spans came the advent of the diseases of civilization: atherosclerotic cardiovascular diseases, type 2 diabetes mellitus, chronic obstructive pulmonary disease, lung and colon cancers, essential hypertension, obesity, diverticulitis, and even dental carries. As of 2011, US life expectancy at birth is 78 years.

    For sure, aerobic fitness is essential to health and longevity in the modern world however, medical science has demonstrated that many of the diseases of civilization would be minimized with appropriate dietary modification. Yes, the same medical science that we are throwing rocks at in the current “cutesy” survey of the AHA offered in this blog session.

    One method of analysis in medical research is the examination of the Paleolithic diet supporting the discordance hypothesis that tries to explain that the mismatch in our modern diet from that what our genome has evolved is the cause of some chronic diseases. As an example, consider the modification of sodium intake. Studies of our ancestors diet estimates their sodium intake at about 800 mg/day, compared to a current adult average of 10,000 mg/day estimated by the WHO. Well-validated computer simulations predict that a reduction of 3000 mg/day (30%) in sodium intake would result in 40,000 to 90,000 fewer deaths from coronary heart and stroke each year in the US. On the other hand, moderate ethanol intake has been shown to reduce cardiovascular risk. Ethanol consumption was probably nonexistence before the invention of agriculture and not part of the paleo lifestyle.

    No one has all the answers but blindly following any particular lifestyle or lifestyle advocate will probably not get you to a healthy 9th decade or simply a healthy older life. However, with a little luck and the judicious adoption of demonstrated healthy habits in fitness, nutrition, and lifestyle we all may get there.

    I think the problem people have with The Heart Scan Blog is that they forget the doctor is referring to people who have metabolic problems. I've met many people who are fat and who eat potatoes and fruits yet keep their cals low and lose a ridiculous amount of weight. But at the same time I know people who, if they ate the same way, they would gain weight.

    In general, the info on this blog is really good. Sure there are times where it seems that the doctor has recanted his hate of weight so much that he begins going after the most random stuff (i.e.. butter), but realize that this is a blog and that - as mentioned previously - everyone is different.

    Closing anecdote: My grandfather is 94. He's incredibly healthy (runs a whole mango farm in Asia). His diet would be deemed bad by most of the people on this blog. He eats oatmeal topped with mangoes for breakfast, Hawaiian Bread with SPAM sandwich (because he's out on the farm), and he eats white rice for dinner. His cholesterol is perfectly fine. His heart is perfectly fine. In fact, the doctors are always amazed at how healthy it is.

    So it goes to show, it depends on YOU. Do your research, see what info is out there, don't rely entirely on any one source of info. So a doctor recommended you a diet you don't agree with? Guess what? Go see another doctor! Just be sure you aren't going from one doctor to another until you hear the answer you WANT to hear as opposed to the one you NEED to hear.

    Thank you to all the  Anonymousi, Lori and Revelo who replied to my question, especially the first responder.  I've downloaded the paper and am looking forward to reading it.  I was pleased to note that, as I believed, those early diets were pretty well balanced.

    And thanks, Lori and another, for pointing out that this site is intended largely for people with CVD and/or metabolic disorders.  (That explains the every 15 min BG readings!)

    I was not questioning because I was confused about which diet to follow, but rather, was confused by the way the term "Paleo" [diet] was being thrown around on this site by several commenters, as in "I've been Paleo for two months now and feel great.  No more carbs for me."  And I wondered if that was the site terminology for the diet plan envisioned by Dr Davis.

    Revelo, I don't think I agree with your statement, " Only after you become lean and conditioned do you really need to start worrying about diet."  First of all, unless you've a metabolic disorder I think you should be mindful rather than worrying about your diet.  Second, I'm inclined to believe that once you're conditioned that's when you can stop worrying, if you were so inclined.  You've cranked up the mitochondria and they're working away at increased effectiveness even while you're not working out.

    By the way, I used to love oatmeal in the morning.   Several years ago I started what turned out to be about two years of oatmeal for breakfast every single morning – with half and half or cream and brown sugar.  Then I stopped as suddenly as I had started.  I think my body needed something the oats supplied, and then it no longer did.  And I stayed slim all that time.  Now I don't touch fructose except in fresh fruit (Thank you, Dr Lustig), so no sugar either white or brown should I ever again get the oatmeal urge.

    To all the "anonymous" posters-

    After reading Dr. Davis' blog for some time now, I can assure you he will respond if the comment is worth his time.

    General bad mouthing is rampant on a blog and if he spent most of his time refuting narrow minded opinions he wouldn't have time to be a cardiologist or write. So chill out or go elsewhere.

    Also- his views aren't directed to just people with metabolic syndrome. It's for people who seem to be the American picture of "health" but are a ticking time bomb for diabetes, stroke, heart attack. His knowledge delves deeper than just a typical lipid panel (LDL, HDL, triglycerides).

    People should know what they speak of, before the pop of at the mouth about topics they aren't well suited to debate.

    Good post Dr. Davis.

    Some are not abreast of the science and how it is clinically relevant. A 33 year 14,000 patient study of Danes, published 18 Feb 2011 in Annals of Neurology, indicates Doc's insistance is well founded.

    (In case you wonder why neurologists' data are relevant it is because 87% of fatal strokes are ischemic strokes. Now on to the science reported.)

    Danes followed those with strokes over 33 years and found that NON-fasting triglyceride levels were more of an indicator than cholesterol level.
    Specificly: women and men with over 89 mg/dl NON-fasting triglycerides had 1.2 times more stroke risk.

    Doc's rants about blood sugar after eating, including butter induced spike, are in line with NON-fasting triglycerides being
    a risk factor. He does detail
    triglyrerides in other posts and goes into the VLDL mechanism too. My layman's focus on LDL & genetics overlooked what this blog clued me in to.

    Laboratory lipid blood work shows the fasting trigylceride number. Doc pushes home test of
    post-meal blood sugar since it is a surrogate of VLDL and NON-fasting triglycerides getting elevated (or not).

  • Might-o'chondri-AL

    2/24/2011 12:08:16 AM |

    Non-diabetics, like me, think blood sugar science is for the other guy. Doc seems to be trying to hammer it home that it is relevant to some more of us.

    Let's focus on coronary problems, like multi-vessel coronary disease, although it is all tied in to cardio-vascular "events". A meta-analysis of 20 studies covering 90,000 non-diabetics is worth summarizing.

    Over 12 years those 90,000 non-diabetics' heart risk (multi-vessel coronary artery disease) correlated exponentially with both fasting and post-meal blood glucose levels. This was irregardless of the person not meeting the diagnostic criteria for being diabetic; and irregardless of "normal" fasting blood sugar, or even signs of glucose intolerance. In other words, the +/- 2 hour span of blood sugar dynamic is connected to cardio-vascular events.

    (Multi-vessel coronary disease is when the left ventricle functions, but there is +/- 70% stenosis narrowing of blood vessel from plaque.)

    European Diabetes Epidemiology Group's 2003 "DECODE" research shows that the interplay  of blood sugar and cardio-vascular risk can start even in the "normal" blood sugar range. The risk progresses in a linear
    fashion, yet there is no specific point where can say individual has passed the point of no return into danger.

    Again, the DECODE data's
    significance is that post-prandial (after meal) glycemia, and to a lesser extent fasting blood sugar level, is relevant to cardio-vascular events even in some non-diabetics.

    Non-diabetics can still share some of the 30 risky genes with type II diabetics and yet not become diabetic. We don't know which of us has what of those allelo-morphs (a.k.a. allele; a DNA sequence on a chromosome).

    So, non-diabetics (specificly those with the alleles similar to diabetics) may have normal fasting &/or normal post-prandial blood sugar yet be at risk of a cardio-vascular event. Furthermore, non-diabetics with suspiciously elevated fasting blood sugar are thought to be manifesting one of those genetic SNPs (single nucleotide polymorphism, a.k.a. mutation).

    Clinically 35% of diabetics have cardio-vascular events and 5 years later 35% of those go on to have a fatal incident. In comparison 24% of non-diabetics have cardio-vascular events, yet 5 years later 33% of those who share the risky allele(s)go on to have a fatal incident. In other words, everybody who took a first "hit" has virtually the same chance of dying; speculation is the non-diabetics who go on to die share the dying
    diabetics risky allele(s).

    Discussing what (say) grand-dads
    eating habits is annecdotal; as is we non-diabetics assumption time won't alter things for us.
    Many of us do not share genes with any diabetic risk, so Doc's "gluco-phobia" is irrelevant. He obviously
    sees plenty, diabetic and non-diabetic, who come to him so they won't die unnecessarily.

    For you who may live long enough to see routine testing, or doing research, here is a list of the 10 alleles most associated with European ancestry adult onset diabetes relevant to what was discussed above.

    It bears mentioning that each may have up to 3 allele sub-variations for each risk
    gene. In no particular order, they are:
    FTO rs8050136, IGFBP2 rs4402960,
    CDKAL1 rs7754840, HHEX rs1111875,
    SVC30A8 rs13266634, PPARG
    rs1801282, KCNJ11 rs5219, TCF7L2
    rs7903146, CDKN2A/B rs10811661and rs93000039.

    Wow. I see I enter a fascinating conversation.

    In response to a question posed by Worldinside: The difficulty with carbohydrates differs substantially from person to person, based on 1) genetics, e.g., apo E2, 2) intensity of physical activity, 3) preceding lifelong carbohydrate exposure, 4) current weight and insulin sensitivity, 5) vitamin D status, 6) lectin content of consumed foods. There are other factors.

    Point: There cannot be a one-size-fits-all approach to diet. This is one of the main reasons I advocate postprandial glucose checks, a means to assess a specific individual's carbohydrate tolerance.

    And thank you, Eric and Terrence, for understanding that this is a blog and that I do my best to respond, given my time constraints. I've just finished a 10 hour day in the office, spent 2 hours starting in the early a.m. editing a new book (to be released by Rodale in fall). I now turn to website responsibilities until late tonite.
