Quieting the insulin storm

The cycle of eating, satiety, and hunger is largely driven by insulin and blood sugar responses.

For instance, if I eat a bowl of Cheerios, my blood sugar will surge to 140 mg/dl or higher (how high depending on insulin sensitivity). The flood of sugar from this Frankenfood triggers the release of insulin; blood sugar then settles back down.

The decline in blood sugar back down to normal or below normal powerfully triggers hunger. Variable degrees of shakiness, mental fogginess, and irritability also commonly occur. Most people experience this to some extent; some experience an exagerrated version called "reactive hypoglycemmia" and can suffer peculiar personality changes, irrational and even violent behavior.

Foods made with wheat or cornstarch raise blood sugar higher and faster than table sugar. Accordingly, blood sugar and insulin swing more widely with these food: highs are higher, lows are lower. People who therefore follow the standard mantra of "eat plenty of healthy whole grains" therefore experience a 2-3 hour long cycle of eating, brief satiety, and recurrent hunger. Cravings for snacks, impulsive eating, and overeating all occur during the period when blood sugar has dropped and hunger is powerfully triggered.

Eliminating this up and down fluctuation is therefore key to regaining control over appetite, losing weight, reducing small LDL and triglycerides, reducing blood sugar, and putting out the fires of inflammatory responses.

You can accomplish this by:

1) Eliminating foods that trigger the exagerrated rises in blood sugar--Wheat, cornstarch, polished rices, white and red potatoes, and candy.

2) Adding a healthy oil to every meal--a strategy that prolongs satiety and helps suppress sugar-insulin fluctuations.

Scare tactics

"You're a walking time bomb."

"I can't be responsible for what happens to you."

"Your blockage is in the artery called the 'widow-maker.'"




Familiar lines? These are the well-rehearsed warnings commonly used by cardiologists to persuade a patient to undergo a procedure (heart catheterization and all that follow).

Something happens when you hear these words about your health. Most people's resolve to explore alternatives, get another opinion, think it over, promptly crumbles when they hear these words. These particular warnings have been time-tested and are surprisingly effective.

Unlike many other conditions, heart disease does indeed result in catastrophic events without warning. Unlike, say, cancer, heart disease can wreak damage suddenly. That's all true.

What bothers me is the vigor with which the opportunity for hospital procedures is pursued.

The thinking is that hospitals procedures = saving a life. In the vast majority of people, this is nonsense. Procedures like heart catheterization, stents, bypass, do save lives if someone is in the throes of a catastrophe. The problem is that most people who undergo procedures are not in the midst of catastrophe and have every hope of avoiding it altogether with some simple efforts towards prevention.

Imagine this conversation: "Yes, Mr. Smith, you do have heart disease, Even though you have no symptoms and your stress test is normal, I believe that we should 1) identify the causes of your heart disease, then 2) correct them. Of course, if you don't want to engage in this prevention process, then there may be a point at which heart procedures may be necessary. But I believe that you have great hopes of avoiding them and avoiding heart attack."

Self-Directed Testing

In the last Heart Scan Blog post, I listed the poll results on success vs. failure in trying to obtain requested blood work through doctors. The results of that informal poll revealed that a substantial number of people encounter resistance to one degree or another in trying to obtain blood tests.

But the world of self-directed testing is growing. In addition to your ability to circumvent your doctor by getting your own blood work done, you can now:

--Obtain many imaging tests on your own--Heart scans can be obtained without your doctor's involvement, for instance. The ultrasound screening services, like that offered by Lifeline, mobile services that provide carotid, abdominal aorta, and osteoporosis screening services; full body scans, and others.
--Identify and treat some conditions--Internet information has gotten quite powerful to assist individuals in recognizing when a condition might be present. (However, this is also a landmine for trouble if not properly used.)
--Genetic testing--While just in its infancy, direct-to-consumer genetic testing is now offered by two outfits that I'm aware of.
--Unusual laboratory tests--e.g., heavy metals, omega-3 fatty acid content, cancer markers.

One drawback to the emerging world of self-directed testing: There is no insurance coverage. However, this will become less and less of an issue as time passes, since it is clear that most Americans will need to bear a greater portion of healthcare costs in future, since some conventional services may even be rationed for cost containment; higher copays and the emergence of medical savings accounts, providing the individual with more control over how healthcare dollars are spent; competition in self-directed healthcare services, which will reduce costs. Imagine, for instance, several more direct-to-consumer services to obtain blood tests appear. They will need to compete on price and service.

While my colleagues are terrified of the potential for abuse of such tests, my reaction is the opposite: I am enormously excited by the potential for individuals to seize more and more control over their health.

Of course, with greater freedom comes greater responsibility. But the long-term net result will be, in my view, a healthier, more satisfied healthcare consumer with reduced healthcare costs.

Self-testing

Here are the results of the latest Heart Scan Blog poll (84 respondents):


When you ask your doctor to perform a specific blood test, does he/she:


Do it without question?
38 (44%)


Do it but express reservations?
25 (29%)


Do it very grudgingly?
13 (15%)


Refuse outright?
9 (10%)



I was encouraged that 44% of respondents are/were able to obtain the blood work they requested without resistance. Sadly, however, the majority do either encounter reluctance or outright resistance.

Why would your doctor impose barriers to your ability to obtain laboratory tests? Well, several potential reasons:

1) He/she feels that they are charged with your health safety, and you might be led down a misleading, potentially dangerous path.

2) He/she feels that the tests are truly unnecessary and that you will be wasting the money of the "system."

3) He/she doesn't understand the tests, or is unfamiliar with them.

4) He/she feels that the doctor should be in complete control, not you. How dare you try to usurp the doctor-as-dictator of your health!


In reality, number 1 is understandable but rarely occurs. I have indeed have had requests, though rare, for outrageously inappropriate tests for the issue at hand, usually due to a misinterpretation of some information by the patient.

I'm not sure how often number 2 truly is. For instance, it is not uncommon for the doctor to have an ownership stake in the laboratory. There are several large primary care groups in Milwaukee who are notorious over-users of laboratory tests, with extraordinary batteries of dozens of tests every few months on the flimsiest reasons , clearly motivated by . . . money. On the other hand, there are physicians who do consciously try and order tests rationally and cost-effectively. I suspect that this is a minority.

I feel quite confident that number 3--your doctor's ignorance--is probably the most common reason he/she is reluctant or refuses to allow you access to a test. Most respondents I suspect are referring to many of the tests that I have been advocating, such as lipoprotein testing, lipoprotein(a), and vitamin D blood levels. I am uncertain how any of these could be construed to be dangerous. But ignorance of the value of these tests is rampant and resistance is nearly always based on not having explored these issues and having no appreciation for their importance. Of course, the beleaguered primary care physician is, no surprise, inundated by so much information across such a wide range that he/she has become expert at nothing, barely able to even deliver the full scope of genuine up-to-date primary services any longer. My colleagues, the cardiologists. . . well, you know my feelings about their attitudes: If it doesn't make money, then why should I bother? Devote months or years studying something that doesn't ring the cash register?

I see this dilemma as yet more evidence of the growing disenchantment with the doctor-as-gatekeeper model, the centuries old paternalistic "I will tell you what to do and you will do it." It worked when the doctor was educated and had access to knowledge you could never realistically obtain because you couldn't read, or you were too poor to afford books and education, or because medical information was made privy only to select people.

It's not that way anymore: The information you have access to is the same information my colleagues and I have access to: a level playing field. Along with the changing rules of the game, the game itself must eventually change.

I believe that people should have access to self-testing. Indeed, there is a growing industry of direct-to-consumer laboratory testing, such as that offered by Life Extension and LabSafe . For the most part, these offer tests without potential insurance reimbursement.

But the landscape is changing: We are just beginning a new age of self-empowerment, self-directed healthcare.

Whenever I say this, some people are angered that the majority of people will be too lazy, stupid, or poor to join the movement. What I am not saying is that we should agitate to make the system a patient-only directed process and completely remove the doctor. What I am saying is that the patient should and will play an increasingly important role in determining the content and direction of his/her care, especially as the patient becomes far more knowledgeable about issues relevant to his/her health.


The new tools of health measurement

If there were a new mantra of the new science of insight into health and long life, it would be “measure, measure, and measure.”

Never before in history have we had access to the analytical, laboratory, imaging, quantifying health tools that we have today. We can locate, scan, measure, all down as far as the level of basic codons of the genetic sequence.

The health-inquiring public has so far been permitted just a tip-of-the-tongue taste of these quantitative phenomena in such things as cholesterol values (“know your numbers!”) and blood pressure. Women now discuss their bone density scores over coffee, men their PSAs (prostate specific antigen).

But a curious irony has emerged: Like early 20th century males uncomfortable with women battling for suffrage, healthcare professionals, themselves comfortable with measurements and numbers, are distinctly uncomfortable when some of the same information falls into the hands of the healthcare consumer.

These phenomena play out in especially dramatic fashion in the world of heart health. The public now has broad access (many without a doctor’s order) to an extraordinary array of health measurement tools that can potentially yield enormous benefits for prevention of the most common conditions, information that can be applied by tracking over time.

Measures like heart scan scores, vitamin D blood levels, lipoprotein(a)--measures that most doctors have little or no interest in obtaining, yet they serve crucial roles in maintaining and tracking your health.

The new paradigm is emerging: the tools are getting better and better, they are becoming more accessible.

Increasing sales, growing the business

I continue my portrayal of the fictional hospital, St. Matthews. Though fictional, it is based on real facts, figures, and situations.

Despite their success, administrators at St. Matthews’s Hospital continually fret over how to further expand their enterprise.

Market share can be increased, of course, by competing effectively with other hospitals, but that can be a tough arena. After all, St. Matthews’ competitors deliver pretty much the same services, and draw areas for patients overlap. The last thing the hospital wants is the appearance that heart care is a “cookie cutter” process, the same everywhere. In fact, this trend has hospital administrators wringing their hands. Two competing hospital systems in town recently launched multi-million dollar ad campaigns employing some of the same aggressive tactics St. Matthews’ marketers used successfully in past.

If St. Matthews is going to grow, new markets will need to be explored. What other strategies can a hospital system use to continue climbing the growth curve?

St. Matthews’ hospital administrators have drawn a number of lessons from other businesses. How about squeezing more procedures out of the population you already take care of? That’s an age-old rule of business: your easiest sales come from repeat customers. A former stent patient is going to “need” annual nuclear stress testing ($4000), more stents (about $25,000–39,000 per hospitalization), CT angiogram ($1800–2400), bypass surgery ($84,000), and so on. “Check-up” catheterizations, though clearly of little or not benefit to patients, are silently encouraged, yet another example of the bonanza of repeat procedures possible.

The lesson that “once a heart patient, always a heart patient” has been honed to an art form in business practices at St. Matthews and other hospitals like it. If you enter the system through your primary care physician or cardiologist, there’s an excellent chance you’ll end up with several procedures, diagnostic and therapeutic, over the ensuing years. Accordingly, St. Matthews provides a very attentive after-discharge follow-up program, complete with access to friendly people, phone centers, “support groups,” and even an occasional festive get-together, all in an effort to ensure future return to the system.

All in all, the St. Matthews Hospital System is a hugely successful operation. It provides jobs for thousands of area residents and provides high-tech, high-quality healthcare. Like any business—and no doubt about it, St. Matthews is a business with all the trappings of a profit-seeking enterprise—it grows to serve its own interests. The tobacco industry didn’t grow to its gargantuan proportions by doing good, but by selling a product to an unsuspecting public. So, too, hospitals.

Curiously, hospitals like St. Matthews continue to operate under the sheltered guise of not-for-profit institution with the associated tax benefits, ostensibly serving the public good. This means that all end-of-year excess revenues are re-invested and not distributed to investors. But non-profit does not mean that individuals within the system can’t benefit, and benefit handsomely. Under St. Matthews’ non-profit umbrella, many businesses thrive: 35 pharmacies, extended care facilities to provide care after hospital discharge, drug and medical device distributors, even a venture capital arm to fund new operations. The financial advantage conferred by “non-profit” status has permitted the hospital to compete with other, for-profit businesses, at a considerable advantage. For this reason, attempts have been made over the years to strip them of what some believe is an unfair advantage; all have failed.

While profits may not fall to the bottom line, money does indeed get paid out to many people along the way. Executives, for instance, pay themselves generous salaries and consulting fees, often from several of the entities in this complex business empire. Physicians are brought in as “consultants” or are awarded “directorships” for hundreds of thousands of dollars per year—Director of Research, Director of Cardiovascular Services, etc. Don’t forget the $3.7 million dollar annual salary paid to the CEO.

Hospitals and doctors have a vested interest in preserving this financial house of cards. They will fiercely battle anyone or anything that threatens the stream of cash. During a recent meeting of important doctors at St. Matthews Hospital, one cardiologist bravely voiced his concern that bypass surgery was performed too freely on too many patients in the hospital. The doctor was promptly and quietly asked to remove himself from the meeting. Several days later, he received a letter announcing his dismissal from the committee.

The silent conspiracy conducted by hospitals and cardiologists serves their own purposes better than the good of the public. Under the guise of good works, hospitals continue to promote strategies which are, for the most part, outdated, inefficient, inaccurate, and expensive. But that’s the rub. Expensive to you and your insurance company means more money for the recipient: your hospital and cardiologist, and the powers that support them. All this occurs while the real solutions that are of benefit to the public continue to be overlooked, hidden in the shadows.

Top Doctor

Dr. Robert Connors is the hospital’s most prized cardiologist.

Practically a fixture in the cath lab, he generates more revenues for the hospital than any of his colleagues. Last year alone, he performed over 1500 procedures, bringing in $18 million dollars to the cath lab, $27 million to the hospital. Dr. Connors is very good at what he does: 55-years old, he has been involved in high-tech heart care since the “early days,” 25 years ago, when hospital procedures really took off.

During his career, he has personally performed over 25,000 heart procedures and has built a reputation as a skilled operator of complex coronary procedures. Because of his skills, he enjoys a vigorous flow of referrals for procedures from dozens of primary care physicians. His skill has also earned him referrals from cardiologist colleagues who seek his abilities for difficult cases.

On any day, Dr. Connors typically schedules up to 12 procedures. His entire day is spent in the cath lab, usually from 7 am until 6 pm. He meets many patients for the first time on the catheterization laboratory table as staff shave their groin, preparing for the procedure. Much of the procedure itself is not even performed by Dr. Connors, but by one or another cardiologists-in-training, a “fellow,” or member of the fellowship the hospital proudly maintains as a clinical teaching institution. Nor will Dr. Connors talk to most patients at the close of the procedure. He leaves that to either the fellow or a nurse. Dr. Connors views himself as a procedural specialist, not someone who has to take care of patients. He gave up seeing patients in his office over 10 years ago.

Dr. Connors’ procedural enthusiasm gained him the attention of drug and medical device manufacturers. Because Dr. Connors lectures widely and advises colleagues, his comments can dramatically alter perceptions of the value of a technology. He has, on many occasions, catapulted an unpopular device to most-asked-for among colleagues, bringing millions in revenues to the manufacturer. One particularly lucrative arrangement he made around 10 years ago involved a “closure” device, a $400 single-use plug used to close the access site made during heart catheterizations. By swaying his colleagues at St. Matthews Hospital, 50 orders per day (one per procedure) tallied $20,000 every day, $7.1 million dollars per year for the manufacturer. Although he’d used other devices on the market, the 5,000 shares of stock he was offered encouraged him to issue glowing comments to colleagues on the superiority of this specific brand of closure device. Now over 90% of all catheterizations at St. Matthews conclude with the device manufactured by the company in which Dr. Connors maintains partial ownership.

Negative comments, on the other hand, topple other products when Dr. Connors sees fit to pan them. For this reason, device and drug manufacturers run straight to Dr. Connors to gain his good graces as soon as possible after a product is released into the market. Because the competition is just as likely to do the same, it has often come down to a bidding war, the company providing the most lucrative arrangement most likely to win.

Thus, Dr. Connors proudly boasts of how many times he has flown to Hawaii, Europe, and other exotic locations at industry expense. He also boasts of how, for $100,000 paid to him for a “consulting fee,” he can overturn the choice of products lining hospital shelves. As the hospital’s annual budget for coronary devices will top $84,000,000 this year, device manufacturers regard the sum paid Connors as a profitable investment.

Despite his lofty status in the hospital, Dr. Connors has long expressed a love-hate relationship with St. Matthews. While he enjoys his work and has made a more than comfortable income, he has long felt that the hospital administration didn’t truly appreciate his contributions. Five years ago, he therefore demanded that he be made “Director of Research.” After all, he had hired a nurse to help him coordinate enrollment of patients into several device trials brought to him by medical device manufacturers. When he encountered an initial lukewarm response from hospital administrators, he threatened to take his “business” elsewhere to a competing hospital. St. Matthews’ administrators gave in. They provided him with the title he wanted, along with $100,000 annual “stipend.”

True story, though names have been changed to protect the guilty.

Is Dr. Connors just an “outlier” among colleagues who toe a more conservative line? Or does his brand of commercial enterprise in hospital heart care represent the ideal that they seek, brazenly and ambitiously seeking to expand the procedural solution to heart disease to the exclusion of patient care and real human interaction?

Disease Engineering

Imagine you contract pneumonia.

You have a fever of 103, you’re coughing up thick, yellow sputum, breathing is getting difficult. You hobble to the doctor, who then fails to prescribe you antibiotics. You get some kind of explanation about unnecessary exposure to antibiotics to avoid creating resistant organisms, yadda yadda. So you make do with some Tylenol®, cough syrup, and resign yourself to a few lousy days of suffering.

Five days into your illness, you’ve not shown up for work, you’re having trouble breathing, and you’re getting delirious. An emergency trip to the hospital follows, where a bronchoscopy is performed (an imaging scope threaded down your airway) and organisms recovered for diagnosis. You’re put on a ventilator through a tube in your throat to support your breathing and treated with intravenous antibiotics. Delayed treatment permits infection to escape into the fluid around your lungs, creating an “empyema,” an extension of the infection that requires insertion of a tube into your chest through an incision to drain the infection. You require feeding through a tube in your nose, since the ventilator prevents you from eating through your mouth. After 10 days, several healing incisions, and a hospital bill totaling $75,000, you’re discharged only to be face eights weeks of rehabilitation because of the extreme toll your illness extracted. Your doctor also advises you that, given the damage incurred to your lungs and airways, you will be prone to more lung infections in the future, and similar situations could recur whenever a cold or virus comes long.

A disease treatable by taking a two week, $20 course of oral antibiotics at home has been converted into a lengthy hospital stay that generated extravagant professional fees, testing, and costly supportive care. You’ve lost several weeks of income. You’re weak and demoralized, frightened that the next flu or virus could mean another trip to the hospital.

Such a scenario would be unimaginable with a common infection like pneumonia, or it would be grounds for filing a malpractice lawsuit. But, as horrific as it sounds in another sphere of healthcare, it is, in effect, analogous to how heart disease is managed in current medical practice.

First, you’re permitted to develop the condition. It may require years of ignoring the telltale signs, it may require your unwitting participation in unhealthy lifestyle choices. Palliative treatments that slow, but don't stop, the progression of disease are prescribed like cholesterol drugs. The process then eventuates in some catastrophe like heart attack or similar unstable heart situation, at which point you no longer have a choice but to submit to major heart procedures. That’s when you receive your heart catheterization, coronary stents, bypass, defibrillators, etc. and you're proudly declared a "success" of medical technology.

Of course, none of these procedural treatments cures the disease, no more than a Band Aid® heals the gash in your leg. The conditions that were present that created your heart disease continue, allowing a progressive disease to worsen. At some point, you will need to return to the hospital for yet more procedures when trouble recurs, which it inevitably does.

A coronary bypass operation costs, on average $85, 653 (AHA 2008 Update; based on 2004 data). That doesn't include the $25,433 cost for the heart catheterization performed by a cardiologist to provide the surgical roadmap of your coronary arteries. If there are any complications of your procedure, then your hospital bill may total a substantially higher figure.

$85, 653 is just the upfront financial pay-off. Over the long run, your life is actually worth far more to the cardiovascular healthcare system because no heart procedure yields a permanent fix. In fact, repeated reliance on the system is the rule.

In fact, over 90% of people who enter the American cardiovascular healthcare system do so through a revolving door of multiple procedures over several years. It is truly a rare person, for instance, who undergoes a coronary bypass operation, never to be seen again the wards of the hospital because he remains healthy and free of catastrophe. A much more familiar scenario is the man or woman who undergoes two or three heart catheterizations, receives 3,4, or 6 stents, followed a few years later by a heart bypass, pacemaker, defibrillator, as well as the tests performed for catastrophe management, such as nuclear stress test, echocardiogram, laboratory blood analysis, and consultation with several specialists. Re-do bypass surgeries--a 2nd, 3rd, or 4th bypass--now comprise 25% of all bypass procedures.

The total revenue opportunity is many-fold higher than the initial 80-some thousand dollars, but instead totals hundreds of thousands of dollars per person.

What motivation can there possibly be to 1) identify coronary disease early, when in its asymptomatic stage, then 2) identify its causes, then 3) correct the causes, and finally 4) shut off the disease? You and I can accomplish this with a few hundred dollars of cost, perhaps a few thousand over many years (to cover costs of fish oil, vitamin D, niacin, and whatever else it takes to stop the expression of the disease). Nobody therefore profits substantially from your prevention effort--except you.

Then what if nobody told you that heart disease could be managed this way? That's what I mean by "disease engineering."

Dr. Steven Gundry on The Livin' La Vida Low-Carb Show

I stumbled on a great interview with cardiothoracic surgeon, Dr. Steven Gundry, on Jimmy Moore's Livin' La Vida Low-Carb Show. (Or, cut and paste: http://www.thelivinlowcarbshow.com/dr-steven-gundry-part-1-episode-179/)

Dr. Gundry has some fun ways of looking at eating and health. I found his comments on the activation of genes (discussed at a very light, non-scientific level) useful. He argues that when humans consume sugar-containing foods, the signal received by the body is that winter is approaching and it's time to build up fat stores in anticipation of the food shortages of cold weather. He finds parallels for this phenomenon in other species. Of course, for humans, winter (in the form of extended calorie deprivation) never comes. In fact, you might argue that, given our excessive reliance on grains, corn, and sugars, that we are, in effect, always in anticipation of a winter that never comes.

I've not read Dr. Gundry's books, but I found this light interview a lot of fun.

Does fish oil ADD to statin therapy?

Yet another patient came to my office today saying, "My primary doctor said that I should stop taking fish oil. He say's that I don't need it because I take Crestor."

The woman was in tears, confused and frightened over a potential disagreement between her doctors.

Is this true? If someone takes a statin drug, like Crestor, Lipitor, Zocor (simvastatin), pravachol, or lovastatin, they don't need to take anything else because the statin drug is so powerful that it eliminates risk?

No. Not even close to the truth.

First of all, let's accept that virtually the entire body of statin drug literature--hundreds of studies, billions of dollars spent--was paid for by the drug industry. It's no news that studies paid for by the sponsor are likely to favor the sponsor. Imagine Ford sponsored a study of Ford vs. GM cars vs. Toyota, paying $10 million to fund the effort. Guess who is likely to come out on top? "Studies show that Ford makes the best car in America." (Sorry, I don't mean to pick specifically on Ford. It's just a widely-recognized brand.)

So that means that the statin literature likely overestimates the benefit of statin drugs. Even so, it's clear from the hundreds of studies performed that the best we can hope for by taking statin drugs is a reduction of heart attack and death from heart attack of 30-35%--best case. That doesn't sound like elimination of risk to me.

What are the incremental benefits of adding omega-3 fatty acids from fish oil added to statins? The best data originate with the JELIS Trial (Effects of eicosapentaenoic acid on major coronary events in hypercholesterolaemic patients (JELIS): a randomised open-label, blinded endpoint analysis), in which 19,000 Japanese participants (who already have a high omega-3 intake from diet, usually ranging from 1800-3000 mg per day) experienced a 19% reduction (relative reduction) in cardiovascular events.

GISSI Prevenzione demonstrated a 28% reduction in heart attack, 45% reduction in death from heart attack with fish oil.

Omega-3 fatty acids from fish oil also:

--Reduce triglycerides dramatically
--Accelerate after-eating clearance of digestive by-products, i.e., they correct post-prandial abnormalities
--Modify the character (fragmentation potential, structural strength) of plaque
--Raise HDL modestly

If you buy your fish oil from Sam's Club, Costco, or other discounter, a healthy dose of fish oil might cost you $3 per month. Compare that to the $120 per month average cost of a statin agent. Why is there even a discussion over this?

Sadly, the doctor on Main Street, U.S.A, is the unwitting puppet of the pharmaceutical industry. The pretty drug company representative with nice legs and a cute smile promises lunch, dinner and . . who knows what else? Wink. The fifty-something, hairline-receding doctor can't resist. "Of course I'll prescribe your drug!"

Don't kid yourself: The drug industry knows precisely how to manipulate the behaviors of the deliverers of their products.

So, do statin drugs make omega-3 fatty acids from fish oil irrelevant? Absolutely not.

It's all about trying to inch closer and closer--not to reduction--but to elimination of risk for heart disease.

HDL: “H” is for “happy”

What role do emotions play in HDL cholesterol?

I’ve often observed a peculiar phenomenon: People who come to the office or hospital in the midst of a difficult emotional situation-e.g., stress at home, financial struggles, hospitalization (usually an unhappy occasion)- can show dramatic drops in HDL cholesterol. Not uncommonly, HDL drops 20 or more mg/dl.

Take Agnes’s case. Agnes had to go to the hospital for an elective procedure, one she’d been dreading for months. Previously, Agnes had been proud of the fact that she’d incrased HDL from 42 mg/dl range all the way up to 71 mg/dl. She accomplished this dramatic increase by eliminating wheat and cornstarch from her diet (which helped her lose 24 lbs), taking vitamin D and omega-3 fatty acids from fish oil, exercise, 2 oz of dark chocolate per day, and a glass of red wine with dinner.

Although I wouldn’t have bothered checking a cholesterol panel for such a procedure, the hospital had a checklist that included a cholesterol panel regardless of necessity. (Such checklists are common in hospitals, meant to ensure that certain basic issues are not overlooked.)

Agnes’ HDL: 29 mg/dl-a 42 mg drop.

Agnes will recover and her HDL will rebound, but the same effect can occur with other stressful situations, such as death in the family, financial worries, marital stress, etc., as well as physical illness.

Interestingly, the opposite may also hold true: Low HDL may increase risk for depression and stress. A study from Finland of 124 depressed persons, for instance, showed a 240% increased likelihood of depression in those with lower HDL cholesterols.

In other words, there seems to be a curious interdependence between HDL and emotions.

Why? Does it represent the indirect effect of adrenaline, cortisol, or other “stress hormones”? Do factors that relate to low HDL, such as unhealthy diet full of carbohydrates and physical inactivity, also tend to cultivate depression?

It certainly seems to be a chicken-egg situation, with one often leading to the other.

Moral of the story: Maintaining a sense of optimism and engaging in activities that bring you satisfaction and enjoyment can help raise HDL, as can strategies such as those followed by Agnes. Avoiding unnecessarily stressful situations can help. HDL is important, since higher levels are associated with much reduced risk for heart disease . . . and perhaps depression.
Fish oil: The natural triglyceride form is better

Fish oil: The natural triglyceride form is better

If you have a choice, the triglyceride form of fish oil is preferable. The triglyceride form, i.e., 3 omega-3 fatty acids on a glycerol "backbone," is the form found in the body of fish that protects them from cold temperatures (i.e., they remain liquid at low ambient temperatures).

Most fish oils on the market are the ethyl ester form. This means that the omega-3 fatty acids have been removed from the glycerol backbone; the fatty acids are then reacted with ethanol to form the ethyl ester.

If the form is not specified on your fish oil bottle, it is likely ethyl ester, since the triglyceride form is more costly to process and most manufacturers therefore boast about it. Also, prescription Lovaza--nearly 20 times more costly than the most expensive fish oil triglyceride liquid on a milligram for milligram basis--is the ethyl ester form. That's not even factoring in reduced absorption of ethyl esters compared to triglyceride forms. Remember: FDA approval is not necessarily a stamp of superiority. It just means somebody had the money and ambition to pursue FDA approval. Period.

Taking any kind of fish oil, provided it is not overly oxidized (and thereby yields a smelly fish odor), is better than taking none at all. All fish oil will reduce triglycerides, accelerate clearance of postprandial (after-eating) lipoprotein byproducts of a meal (via activation of lipoprotein lipase), enhance endothelial responsiveness, reduce small LDL particles, and provide a physical stabilizing effect on atherosclerotic plaque.

But if you desire enhanced absorption and potentially lower dose to achieve equivalent RBC omega-3 levels, then triglyceride forms are better.

Here are cut-and-pasted abstracts of two of the studies comparing forms of fish oil.

Bioavailability of marine n-3 fatty acid formulations.

Dyerberg J, Madsen P, Moller JM et al. 
Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Copenhagen, Denmark.

Abstract

The use of marine n-3 polyunsaturated fatty acids (n-3 PUFA) as supplements has prompted the development of concentrated formulations to overcome compliance problems. The present study compares three concentrated preparations - ethyl esters, free fatty acids and re-esterified triglycerides - with placebo oil in a double-blinded design, and with fish body oil and cod liver oil in single-blinded arms. Seventy-two volunteers were given approximately 3.3g of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) daily for 2 weeks. Increases in absolute amounts of EPA and DHA in fasting serum triglycerides, cholesterol esters and phospholipids were examined. Bioavailability of EPA+DHA from re-esterified triglycerides was superior (124%) compared with natural fish oil, whereas the bioavailability from ethyl esters was inferior (73%). Free fatty acid bioavailability (91%) did not differ significantly from natural triglycerides. The stereochemistry of fatty acid in acylglycerols did not influence the bioavailability of EPA and DHA.

Enhanced increase of omega-3 index in response to long-term n-3 fatty acid supplementation from triacylglycerides versus ethyl esters.

Abstract

There is a debate currently about whether different chemical forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are absorbed in an identical way. The objective of this study was to investigate the response of the omega-3 index, the percentage of EPA+DHA in red blood cell membranes, to supplementation with two different omega-3 fatty acid (n-3 FA) formulations in humans. The study was conducted as a double-blinded placebo-controlled trial. A total of 150 volunteers was randomly assigned to one of the three groups: (1) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as reesterified triacylglycerides (rTAG group); (2) corn oil (placebo group) or (3) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as ethyl ester (EE group). Volunteers consumed four gelatine-coated soft capsules daily over a period of six months. The omega-3 index was determined at baseline (t(0)) after three months (t(3)) and at the end of the intervention period (t(6)). The omega-3 index increased significantly in both groups treated with n-3 FAs from baseline to t(3) and t(6) (P < 0.001). The omega-3 index increased to a greater extent in the rTAG group than in the EE group (t(3): 186 versus 161% (P < 0.001); t(6): 197 versus 171% (P < 0.01)). Conclusion: A six-month supplementation of identical doses of EPA+DHA led to a faster and higher increase in the omega-3 index when consumed as triacylglycerides than when consumed as ethyl esters.

    Thank you for the heads up! Once I exhaust my fish oil, I will switch to the triglyceride form.

    I wanted to drop by and thank you for scaring the sh*t out of me regarding a high wheat carby diet and atenolol.

    My blood pressure seems to be genetic and quite stubborn, but since taking your advice (plus some supplements) I have been able to lower it from 150/100 to around 128/92 and going down.

    Something I have also noticed...my pulse used to be quite high all the time- Around 80-90 (I am 29). Now it is always in the 60s. Could this be due to the supplements? Or low carb? Is this healthy?

    Hi, Flavia--

    Those are all positive changes, including the drop in heart rate. It reflects a reduction in adrenaline. A reduction in heart rate is a powerful marker for overall health.

    Costco is the ethyl ester. It is a fine brand, just less well absorbed, of course.

    I have some vitamin D gelcaps and they smell like fish. Are these oxidized too?

  • Michael

    You say not "overly oxidized" at one point in the post.  

    I am generally concerned about the fish oil I buy being oxidized.  There is a brand of fermented fish oil which purports to avoid this problem of oxidation with storage.  

    Is it your position that concerns about oxidation are sometimes (or at least mine) are overblown?  Or that the oxidation that occurs with normal storage etc. is acceptable?

    Hi Dr Davis,

    If I eat high omega-3 wild salmon once a week, high omega-3 wild sardines once a week, grass pasture butter with 225mg of naturally occurring omega-3 per serving, and organic eggs that have a bit in there as well, do you think I am getting enough for a healthy ratio? I also take the Green Pastures FLCO and HVBO blend.

    I do not eat ANY vegetable oils, ever. I only use coconut oil and ghee to cook, so my O6 intake has got to be pretty low.

    What are your thoughts on being able to obtain adequate levels of healthy omega-3 from foods where it is naturally occurring?

    Thanks,

    Dr. Davis (or others): Based on what you say, since my fish oil brand is silent on what kind, I'm assuming it's the ethyl ester form.  But, I just wanted to check to see if anyone knows for sure: the brand I've been using is Carlson ("The Very Finest Fish Oil"), liquid form in a bottle - not the capsules.

    Dr. Davis,

    Can you comment on the recommended dose for an ApoE 3/4 like me?  I've been told by a BHL educator not take any, but I don't like the idea of that.  I was thinking I may try just 500-600mg/day.  Of course, I've been using Kirkland's which apparently is less bioavailable anyway...

    As a nutritionist who's worked in the fish oil industry for 20+ years, I may be able to add some insight.

    Yes, Triglyceride (TG) and Re-esterified triglyceride (rTG) forms are better absorbed than the Ethyl Ester form (EE). At least in the short term. And the Phospholipid (PL) form is roughly 50% better absorbed than rTG.

    Then why don't we all take PL form found in Krill oil? Well, there isnt much Omega-3 in Krill to begin with. And the PL-bound Krill Omega-3 are very temperature sensitive, so you won't see anyone concentrating it.

    BTW, the folks at Neptune Krill Oil have some unpublished data that shows the difference between TG and EE diminishes to insignificance over time.

    TG form is natural, no need for pre-conversion before absorption. That does not mean that your body won't use EE. It will. Just requires another step. It's just that TRUE natural TG is not very concentrated. Usually about 30% Omega-3 or so. Anything above 50% is likely to be EE. But most EU nations only allow TG form, so if you want a concentrated fish oil, you jack it up to 60 or 70% as EE and then re-esterify it. Additional process and can be done, but it will cost you. I'm currently working with some 90% rTG material. This raw material is 10 to 20X more expensive than what goes into Walmart brand fish oil.

    I'm guessing (but it's a good guess) but more than 95% of fish oil studies are done on EE form. So all the benefits you've read about don't go out the window if you are taking EE instead of TG. Forget Lovaza, next-gen EPA-based drugs like Epadel, Epanova and still-pending AMR-101 are all EE.

    Most fish oils, if not all, sold at retail stores are EE. Because it is cheaper. Specialty and online sources are your best bet for TG and rTG.  Go to 3rd party testing IFOS website and look under product type - it will tell you if it is EE or TG. http://www.ifosprogram.com/ifos/consumerreport.aspx

    Issues with the Dyerberg study: 1) 2 weeks is way too short a duration to figure this out. 2) they did not compare TG oil to a placebo (corn oil?). Instead, they compared it to EE. Comparison to placebo would have put things in perspective. The Neubronner paper addresses this issue.

    As I understand it, part of the tradeoff involves potency and how much EPA/DHA you can pack into a capsule. Ethyl esters are going to be more "compact" than trigylceride chains. I take Life Extension brand, and I honestly don't know which form it is. Perhaps it is the ester form. I get 3600 mg of combined Omega 3 activity from six capsules a day. If the trigyleride form would mean 10 or 12, I don't know that the trade is worth it in money or hassle. I know some of these other brands like Pharmax are supposed to be good, but I draw the line at doing "shots" of unencapsulated fish oil!

    As an aside, does anyone have any suggestions for me? I'm 40, pretty close to ideal weight, non diabetic and I still struggle with high TG, now 292 even with fish oil and 1 gram a day of IR niacin... Not a big wheat eater either although I do have a nasty breakfast cereal habit.

    "Just to check: Are triglyceride forms always in bottles? Or can we also get them in capsules?"

    To say it lightly, I prefer to get them off the back of my fish like wild caught salmon but especially with sardines like Ned referred to since the mercury content is extremely low to nonexistent.

    Also, it may be more beneficial consuming supplements naturally in whole foods, if you can get enough. That in itself is not an easy endeavor. Don't get me wrong, I do take my fish oil capsules especially when consuming high 6:3 ratio foods but am trying to incorporate more nutrient dense foods that contain known rich supplement content.

    It would be nice to see more research addressing synergistic effects of nutrients in foods like Dr. Price's findings regarding fermented cod liver oil and high vitamin butter oil.

    No, not even close.

    It also depends on why you take fish oil and/or obtain omega-3 fatty acids and whether or not you have coronary atherosclerotic plaque, among other things.

  • Jack

    2/3/2011 3:16:28 PM |

    The only brand of canned salmon/tuna and canned sardines I eat is from Wild Planet. I am not affiliated with them and this is not an advertisement, but they really seem to do the whole process perfectly. They also do not add any vegetable oil or water. They have very low mercury content and very high natural omega-3 content. The omega-3 in their tuna is even higher than the salmon. Also, they explain the importance of low mercury and how it all works.

    Have a look at their site:

    I often wonder if krill oil is an even more superior source of DHA and EPA simply because they come within the matrix of phospholipids. Phospholipids, of course, are what makes up our cell membranes, making krill oil extremely bio-available to the cells. I guess we will have to wait for tests to confirm.

    Dr. Davis:

    I'm curious to know where GNC's so-called "Triple Strength Fish Oil"
    product ranks. It comes in a softgel form, each capsule containing EPA+DHA strength of 900mg. It has only a slight hint of fishy-ness in taste. It's not clear to me from the bottle label whether it's in a triglyceride form. I'm not necessarily an advocate of GNC products which are not generally a bargain by any means, but have been satisfied with their quality.

    "struggle with high TG, now 292 even with fish oil and 1 gram a day of IR niacin... "

    1grm just is not high enough in my opinion.  I take 2grms of Now brand Niacin and had a 30% reduction in my Trigs. At C$7 for 100 x 500mg tablets it is a cheap treatment. somewhere between 2-3grms is the level required but you can check studies at www.lipidsonline.org.

    btw.  just wanted to announce that my latest HDL is 50 !  I started with a reading of 28 and had been on a low fat no meat diet for years. Added meat, reduced wheat and other grains over the last 6 months. I guess I am a convert.

    I'm also interested if Dr. Davis can comment here or in one of his articles about the proper dosing for Apo 3/4 people.

    I do notice that lowish doses (1 g or less) doesn't seem to affect my LDL much negatively. However, if I go high, say 3g EPA/DHA or so, then my LDL tends to rise... and it's not the particle size thing giving a false high reading, as it's measured by VAP.

    Somewhat oddly, I have noticed that the EE form causes this rise more often than the TG form, but that could be coincidence.

    And for those interested:

    Barleans (orange, low dose): TG
    (high dose): EE
    Minami (EE, except for MarineEPA)
    Nordic Naturals: rTG
    Meg3: Can be either, but unless specified, it's EE
    Epax: rTG
    Carlson has both forms, as mentioned here
    Coromega (rTG Epax oil (I think))
    Natural Factors: EE

    And pretty much all cheapo store brands are EE.

    Krill oil does absorb better than fish oil, as found in a recent study. However, it's like a 50% or so improvement only (at best), and due to price differences between fish/krill, it doesn't make much economical sense. If the esterified astaxanthin provides a specific benefit, then maybe it's worth it... but no data showing it's the EPA/DHA in krill.

    Bob Savage,

    I'm not aware of any third party tests that have been done.  I am certain that I am correct though because I write the spec sheets.

    A quick test to see whether an oil is EE or not is to put it on polystyrene (styrofoam) because EE will dissolve it but TG will not.  And before anyone gets nervous, this has nothing to do with how EE oils affect your body (unless you eat or are made of styrofoam that is).

    Hi readers.  With all this talk about O3 and fish oil I thought that I would chime in with my experience.  I had a heart attack about 1.5 years ago and got a stent placed in one of my arteries.

    Since then I have been taking Walmart fish oil because it was so cheap.  My chest pains gradually receded after my heart attack and I was doing really great for awhile.  I was actually working pretty hard, doing aerobics for about 30 minutes and lifting weights for about 20 minutes.  My weight on a low carb diet went from 305 to 260 so far.

    I have been on Plavix but my cardiologist told me I could back off from it slowly, so I started taking 6 capsules of Walmart fish oil, 400mg VE, 1000 mg VC, 325 mg aspirin, and only half a 75 mg Plavix.

    Then, I went to Walmart and got a new supply of fish oil.  Upon taking it I started to get pretty strong chest pains and had to stop working out.  I did not associate the problem with the fish oil though.

    One day I came to this blog and read about rancidity in fish oil.  I broke open one of the fish oil caps from Walmart and was overwhelmed by the spoiled fish smell.  I immediately stopped taking the oil and my chest pains gradually diminished.

    My question is whether I am likely right that it was the oxidized fish oil causing the chest pains?  This wasn't a very rigorously controlled experiment. I am not looking for an absolute answer but is it possible that rancid fish oil can cause chest pains?

    Personally, I don't put a lot of faith in studies done on mice. Their biological makeup is different than ours and these studies often give mice mega-doses of whatever they are testing for over very short periods of time, which could have adverse consequences for anyone. I like human trials better.
