Why not just get "perfect" lipids and call it a day?

5. September 2006 William Davis (0)

What if you achieved the Track Your Plaque lipid targets: LDL cholesterol 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl?

After all, these are pretty stringent standards. Compared to national guidelines (the ATP-III Guidelines of the National Cholesterol Educational Panel), the Track Your Plaque 60-60-60 goals are laughably ambitious. There's a lot of wisdom hidden in those numbers. The triglyceride level of 60, for instance, is a level at which triglycerides become essentially unavailable for formation of triglyceride-containing lipoprotein particles such as small LDL and VLDL.

If you get to the 60-60-60 target, isn't that good enough? What if you just held your values there and went about your business? Will coronary plaque stop growing and will your CT heart scan score stop increasing?

Sometimes it will. But, unfortunately, many times it will not. The experience generated through clinical trials bear this out. Studies like the St. Francis Heart Study and the BELLES Trial both showed that just reducing LDL cholesterol is insufficient to stop plaque growth. Beyond the Track Your Plaque experience, there's no clinical trial experience that shows whether the 60-60-60 approach does any better.

In our experience, achieving 60-60-60 is indeed better than just reducing LDL. That makes sense. Just raising HDL from the average of 42 mg/dl for a male, 52 mg/dl for a woman adds advantage. Compound this with triglyceride reduction from the plaque-creating equation, and you've doubled success.

But there's even more. What if you had hidden patterns not revealed by conventional lipids? How about lipoprotein(a)? Small LDL? Postprandial (after-eating) abnormalities? Hypertensive effects (more common than you think)!

In 2006, stopping the increase in your heart scan score is, for most of us, not just a matter of taking Lipitor or its equivalent and sitting back. For nearly all of us, stopping the progression of your score is a multi-faceted effort.

Hospitals: Then and Now

2. September 2006 William Davis (0)

It's 1920. The hospital in your city is a facility run by nuns or the church. It's a place for the very ill, often without hope of meaningful treatment, but nonetheless a place where surgeries take place, babies are born, the injured and chronically ill can find care. No one has health insurance and there's no Medicare. Everyone pays what they can. The hospital is accustomed to doling out plenty of care without compensation. For that reason, they welcome donations and sometimes will build new additions or other facilities in honor of a major donor.

Volunteeers are common, since the wards are understaffed and generally suffering from a shortage of trained nurses and personnel associated with the church. Drugs, such as they are, are often prepared from basic ingredients in the hospital pharmacy. Product representatives hawking medicines and devices are virtually unheard of.

Though their therapeutic tools are limited, the physicians are a proud group, dedicating their careers to healing. The majority of the medical staff volunteer large portions of their time to care for the poor who come to the hospital with very advanced stages of disease: metastatic tumors, advanced heart failure, debilitating strokes, overwhelming septicemia, etc.

Hospitals are usually governed by a board of clergy and physicians who make decisions on how to apply their limited resources and continually seek charitable donations.

Fast forward to present day: Hospitals are high-tech, professional facilities with lots of skilled people, complicated equipment,and capable of complex procedures. While they still house people with advanced illnesses, the floors are also filled with people with much earlier phases of disease. In general, they do a good job, with quality issues scrutinized by a number of official agencies to police practices, incidence of hospital-related infections, medication errors, care protocols, etc.

The hospital of 2006 is a more more effective place than the hospital of 1920. But its aims and operations are different, also. Though some churches are still involved in hospitals, more and more are owned by publicly-traded companies that answer to shareholders--shareholders who want share value to increase. Though donations are still sought, much of the revenues are obtained by concentrating on profitable, large-ticket procedures. More procedures are often generated by advertising.

Because they operate to generate profits, several hospitals in a single city or region compete with one another. The 21st century has therefore witnessed the phenomenon of hospital-owned physicians: more and more practicing physicians are employees of their hospital. That way, the physician brings all his patients and procedures to his hospital, not to a competitor. The top of the funnel is the primary care physician, who tends to see all disease when it first occurs. The primary care physician then sends the patient to the specialist, who is obliged (by contract) to perform his/her procedure in the hsopital paying their salary.

Representatives from companies manufacturing and selling expensive hospital equipment and drugs are everywhere, falling over themselves to gain attention of the physicians using their equipment and the hospital buyers who make purchasing decisions. Millions of dollars can be transacted with just one sale.

The number of volunteers has dwindled. The poor and uninsured are commonly diverted elsewhere, often to a government-funded, and often second-rate, institution. Hospitals measure success by comparing annual revenues and numbers of major procedures.

The hospital of 2006 is a vastly different place than 1920. If you're expecting charitable treatment, compassion, and selfless care, you're in the wrong century. In 2006, the hospital is a business. You don't expect charitable treatment at Wal-Mart or from your car dealer. Don't expect it from your hospital. They are businesses and you are a customer. Recognize this fact, lose the nostalgia for the hospitals of yesterday, and a lot more will become clear to you.

The dreaded small LDL particle

1. September 2006 William Davis (0)

Brian is a 59-year old landscape architect whose starting CT heart scan score was 276.

Brian's food choices at the start were deplorable: a pound of sausage per week, sometimes more; butter on anything and everything; up to two pounds of cheese per week; hot dogs; etc. His lipoproteins were accordingly just as miserable: low HDL, high triglycerides, excessive (postprandial, or after-eating) IDL. Small LDL was a particularly stand-out pattern, with 95% of all LDL particles in the small category.

Brian made a dramatic turnaround in lifestyle and corrected all of his patterns--except for small LDL. After one year, small LDL still occupied 95% of all LDL particles, even though the quantity of LDL had been reduced. In order to help convince Brian that correction of his small LDL was going to be necessary to achieve control oover coronary plaque, I suggested that he undergo another heart scan. His score: 435, or a 57% increase.

Each day that passes, I gain more and more respect for small LDL as a cause for coronary plaque growth. Conventional thought among lipid experts is that small LDL should no longer be a factor if total LDL (e.g., LDL particle number) is reduced. But our experience suggests otherwise: when small LDL persists, we tend to see continued, sometimes frightening, plaque growth.

I therefore asked Brian to intensify his efforts: additional weight loss off his somewhat prominent abdomen (since visceral fat increases small LDL), further reduce wheat products and processed carbohydrates, increase niacin (to 1500 mg per day), and use more raw almonds and oat bran.

Don't let small LDL get the best of you. It is a nasty, sometimes persistent abnormality that has impressive effects on plaque growth.

Winning Through Intimidation

31. August 2006 William Davis (0)

Do you remember the book, Winning Through Intimidation by author Robert J. Ringer?

In his 1984 bestseller, author Ringer details how to succeed in business by overwhelming clients and competition by appearing hugely successful and powerful. Rather than a business card, he'd hand out an elegant book to represent himself. He'd show up in a limousine to a meeting, even when he could barely afford it. He used these tactics, even when he was a small-fry, in commercial real estate and built a successful business following such techniques.

This reminds me a lot of what happens in conventional medical practice: The large and successful hospitals, filled with trained staff and technology, exude legitimacy and success. How can they possibly be wrong? Such overwhelming know-how and multiple levels of expertise mustbe right!

Let's be grateful that we do have access to such high-tech, capable care. Unfortunately, just as Mr. Ringer used deceptive practices to appear something he wasn't, this is also true in hospitals. Not all physicians have your best interests in mind. Their principal concern is how profitable your care can be for them--can you be persuaded to have your stent, bypass, etc.. After all, look around you: Aren't all this equipment and personnel impressive? Aren't you intimidated?

The patient that most recently drove home this issue for me recently was a smart and capable executive who came in for consultation. He had been told by his internist that a surgery (to replace his aorta, a HUGE procedure) was probably necessary. In my view, it was not--his process was simply not that far progressed. The risks for danger over the next several years was virtually nil. Unfortunately, this man, now confused and worried, sought an opinion from the chief of thoracic surgery (in the usual white coat and with professorial demeanor, I'm sure) in a major metropolitan hospital (in Chicago), who promptly rushed him off to the operating room.

The pathology report, cleverly not mentioned in any other of the hospital documentation, showed what I had suspected: this man had mild disease that wasn't even close to requiring surgery. But, with all that technology, $100,000 or so of costs, chief of surgery who looked the part, etc.--they must be right!

Robert Ringer's concepts only ring too true for hospitals and some of the unscrupulous physicians in practice. Don't allow yourself to be intimidated.

Can natural treatments "cure" or "treat" any disease?

30. August 2006 William Davis (0)

According to current FDA policy, the answer is a flat "NO!"

No natural treatment, whether it be fish oil (as a nutritional supplement), l-arginine, vitamin D, magnesium, various flavonoids like theaflavin or resveratrol, can be declared to treat or cure any disease. That's why you see the evasive and vague wording on nutritional supplements, nutraceuticals, and various foods, like "Supports heart health" or "Supports healthy cholesterol". Claiming, for instance, that taking 6000 mg per day of a standard OTC fish will reduce triglycerides and stating so on the label of a supplement is unlawful and prosecutable.

Think what you will of Mr. Kevin Trudeau (author of Natural Cures They Don't Want You to Know About"): visionary, consumer advocate, David vs. the Goliath of the FDA and "Big Pharma", or huckster, scam artist, and one-time felon. But Trudeau got it right on one important issue: The FDA dictates what claims can be made to treat disease. On one of his ubiquitous informercials, Trudeau states:

"...the way the system works today, you have the Food and Drug Administration—the FDA, and you have the drug industry. They really work in tandem. Unfortunately, there’s an unholy alliance there. People don’t know that the majority of commissioners of the FDA, which allegedly regulates the drug industry, and the food industry—Food and Drug Administration, the commissioners of the FDA—the majority of them—go to work directly for the drug companies upon leaving the FDA and are paid millions and millions and millions of dollars. Now in any other format, that would be called bribery; that would be called a conflict of interest; that would be called payoffs. That’s exactly what’s happening right now. So what has occurred is the Food and Drug Administration is really working in tandem with the drug industry to protect their profits. Example: The Food and Drug Administration says that only a drug can diagnose, prevent, or cure any disease."

He goes on to say that

"...the Food and Drug Administration says only a drug--nothing else--can cure, prevent, or diagnose a disease. Therefore the Food and Drug Administration continues to call more and more and more things diseases. Therefore they eliminate all-natural remedies. No one can say what a natural remedy can do if it’s been classified as a disease. So Attention Deficit Disorder is now a disease. Therefore only a drug can cure, prevent, or diagnose it. Cancer is a disease. Acid reflux is now a disease. Obesity is now a disease."

(PLEASE do not construe this as an endorsement of Mr. Trudeau's overall opinions. But I do think he's right on this one point.)

The stated purpose of this restrictive policy is to protect the public. Indeed, in years past before protective legislation, ineffective and even poisonous products were commonly sold as therapeutic treatments. (Remember cocaine and morphine in cold remedies? Lead and other toxic agents were also common.) Unfortunately, a huge gap has emerged as clinical data accumulates that support the efficacy of nutritional treatments and other non-traditional methods to treat or alleviate diseases. Any disease, or anything construed as disease as Trudeau points out, can onlybe treated by a drug.

In the FDA's defense, they have made slow progress in allowing "claims" of benefits for several supplements and food substances, such as the beta-glucan of oat products, soy protein, and most recently barley (for cholesterol reduction). The scrutiny is quite thorough and the wording of the policy is quite specific. Regarding oat products, for instance, the policy states:

"FDA concluded that the beta-glucan soluble fiber of whole oats is the primary component responsible for the total and LDL blood cholesterol-lowering effects of diets that contain these whole oat-containing foods at appropriate levels. This conclusion is based on review of scientific evidence indicating a relationship between the soluble fiber in these whole oat-containing foods and a reduction in the
risk of coronary heart disease.

Food products eligible to bear the health claim include oat bran and rolled oats, such as oatmeal, and whole oat flour...To qualify for the health claim, the whole oat-containing food must provide at least 0.75 grams of soluble fiber per
serving. The amount of soluble fiber needed for an effect on cholesterol levels is about 3 grams per day."

(Source: FDA Talk Paper which can be viewed in its entirety at http://www.fda.gov/bbs/topics/ANSWERS/ANS00782.html.)

In light of the boom in nutritional and non-traditional research that validate or refute efficacy, is such a policy still necessary? Or does it inhibit the open dissemination of information and result in a extraordinary monopolization of health treatment for the drug companies?

This debate will likely rage for the next two or more decades, particularly as drug companies are increasingly viewed as profit-seeking enterprises and more validation is gained by non-drug treatments.

For the moment, don't dismiss a "treatment" because it doesn't come by prescription. But don't reject a drugjust because it is a prescription. We need to strike a healthy, rational balance somewhere in between.

Can procedures alone keep you alive?

29. August 2006 William Davis (0)

My days in the hospital remind me of what heart disease can be like when no preventive efforts are taken--what it used to be like even with my patients before taking a vigorous approach to prevention (though over 12 years ago).

Several cardiologists in my hospital, for instance, express skepticism that heart disease prevention works at all. Yes, they know about the statin cholesterol drug trials. But they claim that, given their experience with the power of coronary disease to overpower an individual's control, statin drugs are just "fluff". Coronary disease is a powerful process that can only begin to be harnessed with major procedures, i.e., a mechanical approach.

So these cardiologists routinely have their patients in the hospital, often once a year, sometimes more, for heart catheterization and "fixing" whatever requires fixing: balloon angioplasty, stents, various forms of atherectomy. Year in, year out, these patients return for their "maintenance" procedures. Their cardiologists maintain that this approach works. The patients go on eating what they like, taking little or no nutritional supplements, and medications prescribed by their primary care physicians for blood pressure, etc. But no real effort towards heart disease prevention beyond these minimal steps.

Can this work? Very little at-home, preventive efforts, but periodic "maintenance" procedures?

It can, perhaps, for a relatively short time of a few years, maybe up to 10 years. But it crumbles after this. The disease eventaully overwhelms the cardiologist's ability to stent or balloon this or that, since it has progressed and plaque has growth diffusely the entire period that maintenance procedures have been performed. In addition, acute illness still occurs with some frequency--in other words, plaque rupture is not affected just because there's a stent in the artery upstream or downstream.

Not to mention this can be misery on you and your life, with risk incurred during each procedure. It's also terribly expensive, with hospitalization easily costing $25,000-$50,000 or more each time. (Compare that to a $250 or so CT heart scan.)

As people become more aware of the potential tools for prevention of heart disease, fewer are willing to submit to the archaic and barbaric practice of "maintenance" heart procedures in lieu of prevention. But it still goes on. If you, or anybody you know, are on this pointless and doomed path, find a new doctor.

Bloodletting, another antiquated health practice

Support your local hospital: HAVE A HEART ATTACK!

25. August 2006 William Davis (0)

I'm kidding, of course. But, in your hospital's secret agenda, that's not too far from the truth. Catastrophes lead to hospital procedures, which then yields major revenues.

Prevention, on the other hand, yields nothing for your hospital. No $8,000 to $12,000 for heart catheterization, several thousand more for a stent, $60,000-plus for a bypass, $25,000 or more for a defibrillator. In other words, prevention of heart attack and all its consequences deprive your hospital of a goldmine of revenue.

The doctors are all too often conspirators. I heard of yet another graphic example today. A man I didn't know called me out of the blue with a question. "I had a heart scan and I had a 'score' that I was told meant a moderate quantity of plaque in my arteries, a score of 157. My doctor said to ignore it. But I got another scan a year later and my score was 178. So I told this to my doctor and he said, 'Let's get you into the hospital. We'll set up a catheterization and then you'll get bypassed.' Of course, I was completely thrown off balance by this. Here I was thinking that the heart scan was showing that my prevention program needed improvement. But my doctor was talking about bypass surgery. Can you help? Does this sound right?"

No, this is absolutely not right. It's another tragedy like the many I hear about every day. Heart scans are, in fact, wonderfully helpful tools for prevention. This man was right: he felt great and the heart scan simply uncovered hidden plaque that should have triggered a conversation on how to prevent it from getting worse. But the doctor took it as a license to hustle the patient into the hospital. Ka-ching!

This sort of blatant money-generating behavior is far from rare. Don't become another victim of the cardiovascular money-making machine. Be alert, be skeptical, and question why. Of course, there are plenty of times when major heart procedures are necessary. But always insist on knowing the rationale behind such decisions, whether it's you or a loved one.

Hospitals contain experts in ILLNESS

25. August 2006 William Davis (0)

Hospitals contain many experts in sickness. This seems obvious. But walk down the hallways of any hospital, and you'll quickly be convinced that hospitals contain almost no experts in health.

People (hospital staff, that is, not the patients) in hospitals are especially good at identifying and treating disease. They lack knowledge of health.

If your nurse is 100 lbs overweight and struggles to walk down the hall because of arthritis in both knees, would you entrust her with health advice?

If your doctor sits down in the cafeteria and eats his lunch of a ham sandwich with cheese on a bun, fried onion rings, and a milkshake and pastry, can you believe that he/she possesses any insight into health and nutrition?

If your physical therapist or cardiac rehabilitation counselor struggles nearly as much as you while climbing a single flight of stairs, can you accept their advice on how to regain your stamina and use exerise to full health advantage?

The answer to all these questions is, of course, no. Hospital staff are generally expert at dressing surgical wounds, stopping bleeding, identifying infections, and providing the support services for surgical and diagnostic procedures. In contrast, they are generally miserable at conveying genuine health advice. They certainly fall short in being examples of health themselves.

To hospitals and their staff, health is a temporary situation that persists only until you become ill. Illness is an inevitability in the hospital staff mindset. Health is a temporary state in between illnesses.

We need to shake off this perverse mentality. Health is the state of life that should dominate our practices and philosophies. Illness via the occasional catastrophe, e.g., broken leg from skiing, car accident, etc., is the province of hospitals. We should gravitate towards this philosphy and away from the over-reliance on hospitals that has come to dominate our present perceptions of health. Hospitals are not glamorous. They are, for the most part, profit-seeking businesses intent on portraying themselves as champions of health.

When I walk down the halls of hospitals, I am shocked and ashamed at the extraordinary examples of ill-health presented by hospital staff. Yet they falsely paint themselves as experts in both illness and health. Don't believe it for a second.

Are there still unexplored causes of heart disease?

23. August 2006 William Davis (0)

I met a woman today. She had her first heart attack at age 37. She just had her 2nd heart attack this morning, at age 40.

Several issues are surprising about her story. First, she's pre-menopausal. Heart attacks before menopause are unusual. We'll occasionally see women have a heart attack before or during menopausal years only if they're heavy smokers and/or they have had diabetes (either type I or type II) for many years. But this young woman had neither. She is slender and has never smoked.

Even more surprising are her basic lipid values: LDL cholesterol 35 mg/dl, HDL 150 mg/dl, triglycerides 317 mg/dl. This is a very unusual pattern.

Unfortunately, this is all developing acutely in the hospital. (I've just met her today--she's not a Track Your Plaquer!) Lipoprotein analysis would be extremely interesting. In particular, I'd like to see whether she has any other markers besides elevated triglycerides of a "post-prandial" abnormality, i.e., persistence of abnormal particles after eating. The high triglycerides make this quite likely.

If this proves true, the omega-3 fatty acids from fish oil will be a lifesaving treatment for her, since they dramatically reduce both triglycerides as well as persistent postprandial particles like intermediate-density lipoprotein (IDL). (Track Your Plaque Members: See the Special Report on Postprandial Abnormalities on the present home page at www.cureality.com for a more in-depth discussion of this fascinating collection of patterns that is just started to be explored.)

In the real world, especially acute care medicine, there's always a kicker: she speaks no English. Unfortunately, communicating the intricacies of a powerful program like ours that aims to identify all causes of heart disease, then corrects then and aims for coronary plaque regression, is difficult if not impossible.

I also do occasionally worry that, given this woman's extraordinary risk at a young age, and overall very unusual lipid patterns (HDL 150?!), if there are causes presently beyond our reach. We have to make use of the tools available to us for now.

Everything causes heart attack!

22. August 2006 William Davis (1)

The media are presently gushing about a recent study that associates caffeine intake with heart attack.

CBS News: That cup of coffee you're craving might not be such a good idea. Research in the September issue of Epidemiology suggests coffee can trigger a heart attack within an hour in some people.

Some reporters and their quoted sources are musing about whether it's the caffeine, cream vs. other whiteners, time of day, interaction with other risk factors, etc.

My advice: Get a grip! How many relatively benign, every day factors in life can be blamed for dire health risks?

The problem with many of these studies is that they are cross-sectional. They do not enroll participants, then "treat" with coffee (or other substance in question) vs. placebo. In other words, it is not a randomized trial, the sort of trial necessary to prove a hypothesis. That's all that can be generated by a study like this one: a hypothesis.

Perhaps there's a bit of warning for the person with uncorrected lipids and lipoproteins, has no idea that they have extensive coronary plaque because they've never had a heart scan, and have a slovenly lifestyle. Maybe that person might have exaggerated risk from a cup of coffee.

But for us, involved and intensively addressing all causes of coronary plaque to the point of stabilizing or reducing it, coffee is likely a non-issue.

For the sake of convenience: Commercial sources of prebiotic fibers

3. May 2015 William Davis (0)

Our efforts to obtain prebiotic fibers/resistant starches, as discussed in the Cureality Digestive Health Track, to cultivate healthy bowel flora means recreating the eating behavior of primitive humans who dug in the dirt with sticks and bone fragments for underground roots and tubers, behaviors you can still observe in extant hunter-gatherer groups, such as the Hadza and Yanomamo. But, because this practice is inconvenient for us modern folk accustomed to sleek grocery stores, because many of us live in climates where the ground is frozen much of the year, and because we lack the wisdom passed from generation to generation that helps identify which roots and tubers are safe to eat and which are not, we rely on modern equivalents of primitive sources. Thus, green, unripe bananas, raw potatoes and other such fiber sources in the Cureality lifestyle.

There is therefore no need to purchase prebiotic fibers outside of your daily effort at including an unripe green banana, say, or inulin and fructooligosaccharides (FOS), or small servings of legumes as a means of cultivating healthy bowel flora. These are powerful strategies that change the number and species of bowel flora over time, thereby leading to beneficial health effects that include reduced blood sugar and blood pressure, reduction in triglycerides, reduced anxiety and improved sleep, and reduced colon cancer risk.

HOWEVER, convenience can be a struggle. Traveling by plane, for example, makes lugging around green bananas or raw potatoes inconvenient. Inulin and FOS already come as powders or capsules and they are among the options for a convenient, portable prebiotic fiber strategy. But there are others that can be purchased. This is a more costly way to get your prebiotic fibers and you do not need to purchase these products in order to succeed in your bowel flora management program. These products are therefore listed strictly as a strategy for convenience.

Most perspectives on the quality of human bowel flora composition suggest that diversity is an important feature, i.e., the greater the number of species, the better the health of the host. There may therefore be advantage in varying your prebiotic routine, e.g., green banana on Monday, inulin on Tuesday, PGX (below) on Wednesday, etc. Beyond providing convenience, these products may introduce an added level of diversity, as well.

Among the preparations available to us that can be used as prebiotic fibers:

PGX

While it is billed as a weight management and blood sugar-reducing product, the naturally occurring fiber--α-D-glucurono-α-D-manno-β-D-manno- β-D-gluco, α-L-gulurono-β-D mannurono, β-D-gluco-β- D-mannan--in PGX also exerts prebiotic effects (evidenced by increased fecal butyrate, the beneficial end-product of bacterial metabolism). PGX is available as capsules or granules. It also seems to exert prebiotic effects at lower doses than other prebiotic fibers. While I usually advise reaching 20 grams per day of fiber, PGX appears to exert substantial effects at a daily dose of half that quantity. As with all prebiotic fibers, it is best to build up slowly over weeks, e.g., start at 1.5 grams twice per day. It is also best taken in two or three divided doses. (Avoid the PGX bars, as they are too carb-rich for those of us trying to achieve ideal metaobolic health.)

Prebiotin

A combination of inulin and FOS available as powders and in portable Stick Pacs (2 gram and 4 gram packs). This preparation is quite costly, however, given the generally low cost of purchasing chicory inulin and FOS separately.

Acacia

Acacia fiber is another form of prebiotic fiber. RenewLife and NOW are two reputable brands.

Isomalto-oligosaccharides

This fiber is used in Quest bars and in Paleo Protein Bars. With Quest bars, choose the flavors without sucralose, since it has been associated with undesirable changes in bowel flora.

There you go. It means that there are fewer and fewer reasons to not purposefully cultivate healthy bowel flora and obtain all the wonderful health benefits of doing so, from reduced blood pressure, to reduced triglycerides, to deeper sleep.

Disclaimer: I am not compensated in any way by discussing these products.

How Not To Have An Autoimmune Condition

20. April 2015 William Davis (0)

Autoimmune conditions are becoming increasingly common. Estimates vary, but it appears that at least 8-9% of the population in North America and Western Europe have one of these conditions, with The American Autoimmune Related Diseases Association estimating that it’s even higher at 14% of the population.

The 200 or so autoimmune diseases that afflict modern people are conditions that involve an abnormal immune response directed against one or more organs of the body. If the misguided attack is against the thyroid gland, it can result in Hashimoto’s thyroiditis. If it is directed against pancreatic beta cells that produce insulin, it can result in type 1 diabetes or latent autoimmune diabetes of adults (LADA). If it involves tissue encasing joints (synovium) like the fingers or wrists, it can result in rheumatoid arthritis. It if involves the liver, it can result in autoimmune hepatitis, and so on. Nearly every organ of the body can be the target of such a misguided immune response.

While it requires a genetic predisposition towards autoimmunity that we have no control over (e.g., the HLA-B27 gene for ankylosing spondylitis), there are numerous environmental triggers of these diseases that we can do something about. Identifying and correcting these factors stacks the odds in your favor of reducing autoimmune inflammation, swelling, pain, organ dysfunction, and can even reverse an autoimmune condition altogether.

Among the most important factors to correct in order to minimize or reverse autoimmunity are:

Wheat and grain elimination

If you are reading this, you likely already know that the gliadin protein of wheat and related proteins in other grains (especially the secalin of rye, the hordein of barley, zein of corn, perhaps the avenin of oats) initiate the intestinal “leakiness” that begins the autoimmune process, an effect that occurs in over 90% of people who consume wheat and grains. The flood of foreign peptides/proteins, bacterial lipopolysaccharide, and grain proteins themselves cause immune responses to be launched against these foreign factors. If, for instance, an autoimmune response is triggered against wheat gliadin, the same antibodies can be aimed at the synapsin protein of the central nervous system/brain, resulting in dementia or cerebellar ataxia (destruction of the cerebellum resulting in incoordination and loss of bladder and bowel control). Wheat and grain elimination is by far the most important item on this list to reverse autoimmunity.

Correct vitamin D deficiency

It is clear that, across a spectrum of autoimmune diseases, vitamin D deficiency serves a permissive, not necessarily causative, role in allowing an autoimmune process to proceed. It is clear, for instance, that autoimmune conditions such as type 1 diabetes in children, rheumatoid arthritis, and Hashimoto’s thyroiditis are more common in those with low vitamin D status, much less common in those with higher vitamin D levels. For this and other reasons, I aim to achieve a blood level of 25-hydroxy vitamin D level of 60-70 ng/ml, a level that usually requires around 4000-8000 units per day of D3 (cholecalciferol) in gelcap or liquid form (never tablet due to poor or erratic absorption). In view of the serious nature of autoimmune diseases, it is well worth tracking occasional blood levels.

Supplement omega-3 fatty acids

While omega-3 fatty acids, EPA and DHA, from fish oil have proven only modestly helpful by themselves, when cast onto the background of wheat/grain elimination and vitamin D, omega-3 fatty acids compound anti-inflammatory benefits, such as those exerted via cyclooxygenase-2. This requires a daily EPA + DHA dose of around 3600 mg per day, divided in two. Don’t confuse EPA and DHA omega-3s with linolenic acid, another form of omega-3 obtained from meats, flaxseed, chia, and walnuts that does not not yield the same benefits. Nor can you use krill oil with its relatively trivial content of omega-3s.

Eliminate dairy

This is true in North America and most of Western Europe, less true in New Zealand and Australia. Autoimmunity can be triggered by the casein beta A1 form of casein widely expressed in dairy products, but not by casein beta A2 and other forms. Because it is so prevalent in North America and Western Europe, the most confident way to avoid this immunogenic form of casein is to avoid dairy altogether. You might be able to consume cheese, given the fermentation process that alters proteins and sugar, but that has not been fully explored.

Cultivate healthy bowel flora

People with autoimmune conditions have massively screwed up bowel flora with reduced species diversity and dominance of unhealthy species. We restore a healthier anti-inflammatory panel of bacterial species by “seeding” the colon with high-potency probiotics, then nourishing them with prebiotic fibers/resistant starches, a collection of strategies summarized in the Cureality Digestive Health discussions. People sometimes view bowel flora management as optional, just “fluff”–it is anything but. Properly managing bowel flora can be a make-it-or-break-it advantage; don’t neglect it.

There you go: a basic list to get started on if your interest is to begin a process of unraveling the processes of autoimmunity. In some conditions, such as rheumatoid arthritis and polymyalgia rheumatica, full recovery is possible. In other conditions, such as Hashimoto’s thyroiditis and the pancreatic beta cell destruction leading to type 1 diabetes, reversing the autoimmune inflammation does not restore organ function: hypothyroidism results after thyroiditis quiets down and type 1 diabetes and need for insulin persists after pancreatic beta cell damage. But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery

Five Powerful Ways to Reduce Blood Sugar

4. April 2015 William Davis (0)

Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess.

If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics.

Among the most powerful and effective strategies to reduce blood sugar:

1) Eat no wheat nor grains

Recall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.

2) Add no sugars, avoid high-fructose corn syrup

This should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.

3) Vitamin D

Because vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.

4) Restore bowel flora

As cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)

5) Exercise

Blood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.

Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health. This is our core mission in Cureality. A nice side benefit: information from Cureality is not accompanied by advertisements from Merck, Pfizer, Kelloggs, Kraft, or Cadbury Schweppes.

Cureality App Review: Breathe Sync

7. March 2015 William Davis (0)

Biofeedback is a wonderful, natural way to gain control over multiple physiological phenomena, a means of tapping into your body’s internal resources. You can, for instance, use biofeedback to reduce anxiety, heart rate, and blood pressure, and achieve a sense of well-being that does not involve drugs, side-effects, or even much cost.

Biofeedback simply means that you are tracking some observable physiologic phenomenon—heart rate, skin temperature, blood pressure—and trying to consciously access control over it. One very successful method is that of bringing the beat-to-beat variation in heart rate into synchrony with the respiratory cycle. In day-to-day life, the heart beat is usually completely out of sync with respiration. Bring it into synchrony and interesting things happen: you experience a feeling of peace and calm, while many healthy phenomena develop.

A company called HeartMath has applied this principle through their personal computer-driven device that plugs into the USB port of your computer and monitors your heart rate with a device clipped on your earlobe. You then regulate breathing and follow the instructions provided and feedback is obtained on whether you are achieving synchrony, or what they call “coherence.” As the user becomes more effective in achieving coherence over time, positive physiological and emotional effects develop. HeartMath has been shown, for instance, to reduce systolic and diastolic blood pressure, morning cortisol levels (a stress hormone), and helps people deal with chronic pain. Downside of the HeartMath process: a $249 price tag for the earlobe-USB device.

But this is the age of emerging smartphone apps, including those applied to health. Smartphone apps are perfect for health monitoring. They are especially changing how we engage in biofeedback. An app called Breathe Sync is available that tracks heart rate using the camera’s flash on the phone. By tracking heart rate and providing visual instruction on breathing pattern, the program generates a Wellness Quotient, WQ, similar to HeartMath’s coherence scoring system. Difference: Breathe Sync is portable and a heck of a lot less costly. I paid $9.99, more than I’ve paid for any other mainstream smartphone application, but a bargain compared to the HeartMath device cost.

One glitch is that you need to not be running any other programs in the background, such as your GPS, else you will have pauses in the Breathe Sync program, negating the value of your WQ. Beyond this, the app functions reliably and can help you achieve the health goals of biofeedback with so much less hassle and greater effectiveness than the older methods.

If you are looking for a biofeedback system that provides advantage in gaining control over metabolic health, while also providing a wonderful method of relaxation, Breathe Sync, I believe, is the go-to app right now.

How did Cureality get its start?

27. July 2014 William Davis (0)

In the Cureality program, we embrace information and strategies that empower you in health without drugs, without hospitals, without procedures. We convert your doctor from director of healthcare to your assistant in health. He or she is there when you need help, but you largely direct your own health future.

How did we gain the know-how, information, tools, even chutzpah to take on such an ambitious project?

It started around 10 years ago with the awkwardly named Track Your Plaque program. In fact, some of the current followers of the Cureality program are former Track Your Plaque members, having learned of the wonderful list of strategies that can be adopted to gain better control over, even reverse, coronary atherosclerotic plaque and risk for heart attack. They also learned that something special happens when you engage with other people with similar interests, all sharing ideas, insights, and resources to get the self-directed health job done. Over time, what started out as simply a source of better information for coronary health evolved into a self-directed coronary disease management program. We never set out to create something as wildly ambitious as a do-it-yourself-at-home coronary disease risk management program, but that is how it inadvertently turned out.

How we went from Information Provider to Health Empowerment Program

So we never intended to take on something so seemingly impossible as managing coronary risk on your own. But, because we armed people with such empowering, profound insights into better ways to manage their heart disease risk beyond “don’t smoke, cut saturated fat, be active, and take a statin drug”—the typical advice offered by doctors—they returned after an interaction with their doctors disappointed: doctors often declared such strategies unnecessary, or the doctor didn’t understand them—even when there were clear-cut clinical data already available to support their use. In other words, the patients—everyday people, not experts—knew more than their doctors.

This flip-flop in the balance of knowledge made for some very interesting stories, like “Harold” (not his real name) who, having survived a heart attack and received a stent, was told by his doctor to cut his fat intake, eat more whole grains, exercise, take aspirin and a beta blocker drug, and reduce his cholesterol values with a statin drug. Upon learning all the additional information from the Track Your Plaque program, Harold returned to his doctor and asked “I’m not so ready to just go along with this idea of ‘reducing cholesterol’ to address heart disease risk. Because my goal is to gain as much control over coronary disease as possible, maybe even reverse it, I’d like to address some additional issues that I believe may be important. I’d like to have my advanced lipoproteins drawn to measure the proportion of small LDL particles I have, whether I have lipoprotein(a), an omega-3 fatty acid index and 25-hydroxy vitamin D level, and a thyroid assessment. Oh, and I believe I should also have an assessment of my inflammation status, perhaps a c-reactive protein and phospholipase A2, and my blood sugar status measured with a fasting glucose, insulin, and hemoglobin A1c.” Harold’s doctor was dumbfounded and speechless. Rather than reveal his ignorance, his doctor advised Harold that none of that was necessary, sending him on his way and telling him that he was fine.

But this left Harold with a sour taste in his mouth, having engaged in many online discussions with people who had followed conventional advice that resulted in more heart attack, more heart procedures—the conventional answers simply did not work. He also discussed his situation with people who had successfully obtained the additional information he sought, added it to their program and enjoyed dramatically improved health, including freedom from more heart attacks, heart symptoms, and heart procedures, as well as improved overall health. So Harold found an easy way to obtain the testing on his own. Within a couple of weeks, he returned to his online community and shared all his information. Within moments, he was provided useful discussion to help him understand the values, all leading to changes in nutrition, nutritional supplement choices, how and where to get the simple tools necessary, such as iodine and vitamin D supplements. He even entered his data, choosing which values he was willing to share with others, which remained private, allowing him to compare his own follow-up values several months later. Engaged in this process, self-directed but collaborative, he witnessed marked transformations in his health. Not only did he never again—over several years—ever re-develop heart symptoms nor require any more trips back to the cath lab, he lost weight, reversed a pre-diabetic sugar profile, improved his cholesterol values without drugs, got rid of the acid reflux symptoms he endured for many years, dropped his blood pressure to normal, enjoyed better mood, energy, and sleep. Slender, healthier, all accomplished without his doctor.

Harold returned to his doctor for a routine follow-up. Slender, energetic, without complaints, on no drugs except the aspirin for his stent, the basic laboratory assessment his doctor ordered in front of him, his doctor admitted,” Well, I don’t know how you’re doing it, but these values look like a 20-year old substituted his blood for yours. They’re unbelievable. What drugs are you taking to do this?” “No drugs,” Harold replied, “I’m following a program to reverse heart disease, but it means doing some things that are different from conventional solutions.” His doctor closed their meeting with the signature response of doctors nationwide: “Well, I don’t understand what you are doing, but just keep doing it.”

Yes, Harold knew more about how to control heart disease than his doctor, more than his cardiologist. The cardiologist knew how to insert a stent or defibrillator. But deliver information that empowered Harold in all aspects of health from head to toe, while also dramatically reducing, perhaps eliminating, his coronary disease risk? As you now know, that is not what conventional healthcare does, nor is it interested in doing so, as it would relinquish control and threaten to cut off this hugely profitable revenue stream that drives “healthcare.”

Having managed to inadvertently create a self-directed coronary risk management program with such spectacular results and in probably one of the most difficult areas of all—heart disease—it became clear that a similar approach could be even more easily applied to many other areas of health, such as weight loss, bone health, cholesterol and blood pressure issues, diabetes and pre-diabetes, hormonal health, autoimmune conditions, and others. You can do it when empowered by safe, effective information, and supported by a community of sharing and collaboration. We don’t fire our doctors; they are there when we need them when, for instance, we get injured or catch pneumonia, or as an occasional resource. But doctors should no longer be able to get away with neglect, misinformation, or blindly directing you to the next revenue-generating procedure because you are empowered by the information and support you receive in Cureality.

As we get more effective in delivering this information and new tools to you, just imagine what we can accomplish in this new age of information and self-empowerment. The future for us is bright with ambitions for better interactive tools with Cureality expert staff, better ways to crowd source health answers, provide more engaging community conversation, all while the health insights that help accomplish our self-directed health goals get better and better. Each person that joins Cureality helps make this service more effective because your wisdom, insights, and experience are added to the collective knowledge. We are more powerful together than we are as individuals.

If you are already a Cureality Member, please add your comments and questions to the growing conversation. If you are not a Member, consider joining our discussions, as each new voice gets us closer and closer to better answers to take back control over health.

Power in Numbers

25. June 2014 William Davis (0)

In his book, The Wisdom of Crowds, author James Surowiecki begins with the story of an ox judging competition in which 800 people—not ox experts nor breeders, just ordinary people attending a county fair—were asked to guess the weight of the ox. The competition was conducted by a scientist, Francis Galton, who held a low opinion of the intelligence of the average person, remarking that “the stupidity and wrong-headedness of many men and women being so great as to be scarcely credible.” He hoped to prove, by examining the various guesses, that the average person had no idea of how to judge the real answer. After all participants casted their written votes, Galton tallied up the total and averaged the result: 1,197 pounds—just one pound off from the real weight of 1,198 pounds. Few individuals actually guessed the correct weight themselves but, when the opinions of many were combined, the result was near-perfect.

Crowds can also be a source of irrational behavior, panic, and stampede. Witness any modern football or soccer game, for instance, in which fights break out over an issue as minor as a disputed call or a heckle. Or go back through history to the countless events when mass hysteria ruled, such as the Salem Witch Trials or Orson Welles’ War of the Worlds radio broadcast.

Let’s put aside examples of mass emotional chaos of the sort that causes crowds to stampede store doors on Black Friday. Let’s focus instead on conscious, considered, thoughtful opinions. We all accept that there are as many opinions on issues as there are people, not uncommonly with widely divergent views. But can we, as Galton’s famous experiment did, combine the opinions of many and come away with some fruitful insight—the correct answer? Just as the people participating in Galton’s experiment were not experts, so Cureality participants—a crowd-sourced collection of opinions—are not experts. If we were to poll everyone to identify their area of expertise or experience, it would likely include finance, the retail industry, raising children, or teaching—but not health. Yes, we have experts curating the direction of content, but we also crowd-source collective opinion.

Right now, Cureality is based on existing science, the philosophy of self-directed health, combined with guidance and community to help the participant along in the sometimes complex world of health questions. But as our processes and procedures improve, can we—like Galton’s ox weight guessers—come away with coalescent wisdom, answers to our health questions, near-perfect solutions to health conditions that have eluded the “experts” for centuries?

I think that we can. No, I know that we can. We enter a new age in information and harness the power of the crowd-sourcing of solutions, even when no single individual has the complete answer herself.

What is Cureality all about?

27. May 2014 William Davis (1)

“Looking over your medical record, Nancy, I’m a bit concerned about your risk for osteoporosis and hip fracture. It looks like your mom had a hip fracture at age 67. Is that right? ”

“Yes, she did,” Nancy responded. “And her life was never quite the same for the 15 years she lived after that.

“You’re 53 year old. Bone thinning develops over many years. Let’s get you scheduled for a bone scan.”

Two weeks later:

“Your z-score is 1.5, Nancy. This means you’ve got a mild form of osteoporosis called ‘osteopenia.’ Here: This is a prescription for alendronate, what used to be called Fosamax.”

“Aren’t there side-effects with that drug? A friend of mine said that her mom had a leg fracture from it.”

“Well, yes. All prescription drugs have potential side-effects. They’re rare, but they can happen and we can’t predict it. Besides leg fracture, there’s something called jaw osteonecrosis in which the jawbone dies and has to be surgically replaced. But would you rather run the risk of a hip fracture?”

“Before we jump to drugs, aren’t there natural things I could do first?”

(Big sigh.) “You can take calcium, but that only helps a bit. You’ve got to make a choice: Take the drug or risk a hip fracture.”

“I’m going to explore some natural remedies on my own first.”

Nancy’s dialogue with her doctor is fictional but based on similar encounters that occur thousands of times every day nationwide. Identify a problem, prescribe a drug. Natural remedies? “They don’t work.” “I don’t know anything about that.” “None of that is proven.” “I only practice evidence-based medicine.” You’ve probably heard a few of these explanations yourself if you ever question the wisdom of conventional medical care.

Each of Nancy’s fictitious interactions were no more 10 minutes long. If she is like most people, she will have one or two such interactions over the course of a year, unless she develops some acute illness. So she’s got something like 20-30 minutes per year to compress all of her “health” advice into the time allotted. 20-30 minutes per year to discuss bone health, nutrition, blood sugar issues, cholesterol issues, blood pressure, female issues, and all the other facets of health. Perhaps she has developed some chronic gastrointestinal complaints, too, and an odd rash on her elbows, maybe headaches a few times per week that she didn’t have before. Regardless, she’s going to have to make do with those few minutes, likely receiving one or more prescriptions or imaging procedures for each.

Such is the nature of modern healthcare: Provide the minimum interaction, address only a few, perhaps no more than one, problem, then prescribe a drug. This is, more often than not, wrong. Plain wrong. Tragically, awfully, unethically, unnecessarily wrong.

Let’s pick up again with Nancy. Upon learning of her osteopenia and long-term risk for hip fractures of the sort that changed her mom’s life and health irretrievably, Nancy started searching for solutions. Not only did she discover that, yes, there are indeed a number of safe and effective ways to deal with osteopenia. She also learned that such strategies have even been examined in clinical trials, some of the strategies pitted head-to-head with drugs and performed on a par, sometimes better, than prescription drugs. She also found that there are online communities that she could join and discuss her health situation with people all sharing the same health interests. During one such interaction at the start of her effort, when she was still a bit unsure and tentative, a woman she didn’t know but who shared a similar interest in restoring bone health, commented to Nancy, “Don’t sweat it, Nancy. I was in your shoes a little over a year ago. I followed a program for bone health: vitamin D, vitamin K2, magnesium, I made sure that I included leafy green vegetables at least once or twice per day, and I added strength training for a few minutes twice per week. I started with osteoporosis. My most recent bone density test showed that I reversed it completely—it’s entirely normal! So hang in there and be sure to share your questions and concerns with us here.”

THAT is what Cureality is all about. Cureality fills the gap of knowledge in health that is not being provided in a few minute-long medical interaction. Cureality reveals the astounding amount of credible, safe, scientific information that allows you to participate, sometimes take over completely, various aspects of health. You don’t have to fire your doctor; these efforts supplement the information and advice you obtain (or don’t obtain) in the doctor’s office. While critics may sometimes say that this can be dangerous or that misdiagnoses and dangerous treatments might be risked, our experience is the exact opposite: People do better by taking the reins of health themselves, choosing to use the health care system for acute or catastrophic illness—but not necessarily for health.

Our fictional woman, Nancy, returns to her doctor one year later after undergoing a repeat bone scan. The doctor opened her chart, clearly expecting to scold her for her foolhardy and careless attitude. Instead, he was speechless. After a pause, he said, “I don’t know how you did it, but your bone density is now normal, the density of a healthy 30-year old woman. Just continue doing what you’re doing.” He closed the chart and walked out.

Yes: “Just continue what you are doing”—not “Please tell me what you did so that I might learn something new,” or “Where did you learn about such strategies? I knew nothing about this!” Just “do what you’re doing.” Too often, that is the response you get that defines what modern health care has become.

You don’t want that kind of health care. Sure, it’s reassuring to know that the doctor and hospital are there in case you injure yourself or develop pneumonia. But obtain day-to-day health advice of the sort that keeps you slender, keeps blood pressure normal, maintains normal insulin and blood pressure responses, helps keep bowel health ideal, can even be used to reverse conditions such as autoimmune joint pain, diabetes, osteoporosis, or skin rashes, while costing next to nothing and yielding health care benefits for you and your family in multiple areas of health? That is the kind of health care you want.

That’s why we developed Cureality.

Omega-3 fatty acids likely NOT associated with prostate cancer

18. July 2013 William Davis Omega-3 fatty acids (6)

A weakly constructed study was reported recently that purportedly associated higher levels of omega-3 fatty acid blood levels and prostate cancer. See this CBS News report, for instance.

Lipid and omega-3 fat expert, Dr. William Harris, posted this concise critique of the study, exposing some fundamental problems:

First, the reported EPA+DHA level in the plasma phospholipids in this study was 3.62% in the no-cancer control group, 3.66% in the total cancer group, 3.67% in the low grade cancer group, and 3.74% in the high-grade group. These differences between cases and controls are very small and would have no meaning clinically as they are within the normal variation. Based on experiments in our lab, the lowest quartile would correspond to an HS-Omega-3 Index of <3.16% and the highest to an Index of >4.77%). These values are obviously low, and virtually none of the subjects was in “danger” of having an HS-Omega-3 Index of >8%. So to conclude that regular consumption of 2 oily fish meals a week or taking fish oil supplements (both of which would result in an Index above the observed range) would increase risk for prostate cancer is extrapolating beyond the data.

This study did not test the question of whether giving fish oil supplements (or eating more oily fish) increased PC risk; it looked only a blood levels of omega-3 which are determined by intake, other dietary factors, metabolism and genetics.

The authors also failed to present the fuller story taught by the literature. The same team reported in 2010 that the use of fish oil supplements was not associated with any increased risk for prostate cancer. A 2010 meta-analysis of fish consumption and prostate cancer reported a reduction in late stage or fatal cancer among cohort studies, but no overall relationship between prostate cancer and fish intake. Terry et al. in 2001 reported higher fish intake was associated with lower risk for prostate cancer incidence and death, and Leitzmann et al. in 2004 reported similar findings. Higher intakes of canned, preserved fish were reported to be associated with reduced risk for prostate cancer. Epstein et al found that a higher omega-3 fatty acid intake predicted better survival for men who already had prostate cancer, and increased fish intake was associated with a 63% reduction in risk for aggressive prostate cancer in a case-control study by Fradet et al). So there is considerable evidence actually FAVORING an increase in fish intake for prostate cancer risk reduction.

Another piece of the picture is to compare prostate cancer rates in Japan vs the US. Here is a quote from the World Foundation of Urology:

"[Prostate cancer] incidence is really high in North America and Northern Europe (e.g., 63 X 100,000 white men and 102 X 100,000 Afro-Americans in the United States), but very low in Asia (e.g., 10 X 100,000 men in Japan).”

Since the Japanese typically eat about 8x more omega-3 fatty acids than Americans do and their
blood levels are twice as high, you’d think their prostate cancer risk would be much higher...
but the opposite is the case.

Omega-3 fatty acids are physiologically necessary, normalizing multiple metabolic phenomena including augmentation of parasympathetic tone, reductions of postprandial (after-meal) lipoprotein excursions, and endothelial function. It would indeed make no sense that nutrients that are necessary for life and health exert an adverse effect such as prostate cancer at such low blood levels. (Recall that an omega-3 RBC index of 6.0% or greater is associated with reduced potential for sudden cardiac death.)

I personally take 3600 mg per day of EPA + DHA in highly-purified, non-oxidized triglyceride form (Ascenta Nutrasea liquid) that yields an RBC omega-3 index of just over 10%, the level that I believe the overwhelming bulk of data suggest is the ideal level for humans.

Are statins and omega-3s incompatible?

18. June 2013 William Davis (4)

French researcher, Dr. Michel de Lorgeril, has been in the forefront of thinking and research into nutritional issues, including the Mediterranean Diet, the French Paradox, and the role of fat intake in cardiovascular health. In a recent review entitled Recent findings on the health effects of omega-3 fatty acids and statins, and their interactions: do statins inhibit omega-3?, he explores the question of whether statin drugs are, in effect, incompatible with omega-3 fatty acids.

Dr. Lorgeril makes several arguments:

1) Earlier studies, such as GISSI-Prevenzione, demonstrated reduction in cardiovascular events with omega-3 fatty acid supplementation, consistent with the biological and physiological benefits observed in animals, experimental preparations, and epidemiologic observations in free-living populations.

2) More recent studies (and meta-analyses) examining the effects of omega-3 fatty acids have failed to demonstrate cardiovascular benefit showing, at most, non-significant trends towards benefit.

He points out that the more recent studies were conducted post-GISSI and after agencies like the American Heart Association's advised people to consume more fish, which prompted broad increases in omega-3 intake. The populations studied therefore had increased intake of omega-3 fatty acids at the start of the studies, verified by higher levels of omega-3 RBC levels in participants.

In addition, he raises the provocative idea that the benefits of omega-3 fatty acids appear to be confined to those not taking statin agents, as suggested, for instance, in the Alpha Omega Trial. He speculates that the potential for statins to ablate the benefits of omega-3s (and vice versa) might be based on several phenomena:

--Statins increase arachidonic acid content of cell membranes, a potentially inflammatory omega-6 fatty acid that competes with omega-3 fatty acids. (Insulin provocation and greater linoleic acid/omega-6 oils do likewise.)
--Statins induce impaired mitochondrial function, while omega-3s improve mitochondrial function. (Impaired mitochondrial function is evidenced, for instance, by reduced coenzyme Q10 levels, with partial relief from muscle weakness and discomfort by supplementing coenzyme Q10.)
--Statins commonly provoke muscle weakness and discomfort which can, in turn, lead to reduced levels of physical activity and increased resistance to insulin. (Thus the recently reported increases in diabetes with statin drug use.)

Are the physiologic effects of omega-3 fatty acids, present and necessary for health, at odds with the non-physiologic effects of statin drugs?

I fear we don't have sufficient data to come to firm conclusions yet, but my perception is that the case against statins is building. Yes, they have benefits in specific subsets of people (none in others), but the notion that everybody needs a statin drug is, I believe, not only dead wrong, but may have effects that are distinctly negative. And I believe that the arguments in favor of omega-3 fatty acid supplementation, EPA and DHA (and perhaps DPA), make better sense.

DHA: the crucial omega-3

22. May 2013 William Davis (5)

Of the two omega-3 fatty acids that are best explored, EPA and DHA, it is likely DHA that exerts the most blood pressure- and heart rate-reducing effects. Here are the data of Mori et al in which 4000 mg of olive oil, purified EPA only, or purified DHA only were administered over 6 weeks:

□ indicates baseline SBP; ▪, postintervention SBP; ○, baseline DBP; •, postintervention DBP; ⋄, baseline HR; and ♦, postintervention HR.

In this group of 56 overweight men with normal starting blood pressures, only DHA reduced systolic BP by 5.8 mmHg, diastolic by 3.3 mmHg.

While each omega-3 fatty acid has important effects, it may be DHA that has an outsized benefit. So how can you get more DHA? Well, this observation from Schuchardt et al is important:

DHA in the triglyceride and phospholipid forms are 3-fold better absorbed, as compared to the ethyl ester form (compared by area-under-the-curve). In other words, fish oil that has been reconstituted to the naturally-occurring triglyceride form (i.e., the form found in fresh fish) provides 3-fold greater blood levels of DHA than the more common ethyl ester form found in most capsules. (The phospholipid form of DHA found in krill is also well-absorbed, but occurs in such small quantities that it is not a practical means of obtaining omega-3 fatty acids, putting aside the astaxanthin issue.)

So if the superior health effects of DHA are desired in a form that is absorbed, the ideal way to do this is either to eat fish or to supplement fish oil in the triglyceride, not ethyl ester, form. The most common and popular forms of fish oil sold are ethyl esters, including Sam's Club Triple-Strength, Costco, Nature Made, Nature's Bounty, as well as prescription Lovaza. (That's right: prescription fish oil, from this and several other perspectives, is an inferior product.)

What sources of triglyceride fish oil with greater DHA content/absorption are available to us? My favorites are, in this order:

Ascenta NutraSea
CEO and founder, Marc St. Onge, is a friend. Having visited his production facility in Nova Scotia, I was impressed with the meticulous methods of preparation. At every step of the way, every effort was made to limit any potential oxidation, including packaging in a vacuum environment. The Ascenta line of triglyceride fish oils are also richer in DHA content. Their NutraSea High DHA liquid, for instance, contains 500 mg EPA and 1000 mg DHA per teaspoon, a 1:2 EPA:DHA ratio, rather than the more typical 3:2 EPA:DHA ratio of ethyl ester forms.

Pharmax (now Seroyal) also has a fine product with a 1.4:1 EPA:DHA ratio.

Nordic Naturals has a fine liquid triglyceride product, though it is 2:1 EPA:DHA.

Why does wheat cause arthritis?

13. November 2010 William Davis (48)

Wheat causes arthritis.

Before you say "What the hell is he saying now?", let me connect the dots on how this ubiquitous dietary ingredient accelerates the path to arthritis in its many forms.

1) Wheat causes glycation--Glycation is glucose-modification of proteins in the body that occurs when blood glucose exceeds 100 mg/dl. Cartilage cells are especially susceptible to glycation. The cartilage cells you had at age 18 are the very same cartilage cells you have at age 60, since they lack the ability to reproduce and repair themselves. Proteins in cartilage are highly susceptible to glycation, which makes them stiff and brittle. Stiff, brittle cartilage loses its soft, elastic, lubricating function. Damaged cartilage cells don't regenerate nor produce more protective proteins. This allows destruction of cartilage tissue, inflammation, and, eventually, bone-on-bone arthritis.

Because wheat, even whole wheat, sends blood sugar higher than almost all other foods, from table sugar to Snickers bars, glycation occurs after each and every slice of toast, every whole wheat bagel, every pita wrap.

2) Wheat is acidifying--Humans are meant to consume a diet that is net alkaline. While hunter-gatherers who consume meat along with plentiful vegetables and fruits live a net alkaline diet (urine pH 7 to 9), modern humans who consume insufficient vegetables and too much grain (of which more than 90% is usually wheat) shift the body towards net acid (urine pH 5 to 7). Wheat is The Great Disrupter, upsetting the normal pH balance that causes loss of calcium from bones, resulting in decalcification, weakness, arthritis and osteoporotic fractures.

3) Wheat causes visceral fat--The extravagant glucose-insulin surges triggered by wheat leads to accumulation of visceral fat: wheat belly.

Visceral fat not only releases inflammatory mediators like tumor necrosis factor and various interleukins, but is also itself inflamed. The inflammatory hotbed of the wheat belly leads to inflammation of joint tissues. This is why overweight and obese wheat-consuming people have more arthritis than would be explained by the burden of excess weight: inflammation makes it worse. Conversely, weight loss leads to greater relief from arthritis pain and inflammation than would be explained by just lightening the physical load.

We need a name for this wheat effect. How about "bagel bones"?

Why do morphine-blocking drugs make you lose weight?

10. November 2010 William Davis (24)

Naloxone (IV) and naltrexone (oral) are drugs that block the action of morphine.

If you were an inner city heroine addict and got knifed during a drug deal, you'd be dragged into the local emergency room. You're high, irrational, and combative. The ER staff restrain you, inject you with naloxone and you are instantly not high. Or, if you overdosed on morphine and stopped breathing, an injection of naloxone would reverse the effect immediately, making you sit bolt upright and wondering what the heck was going on.

So what do morphine-blocking drugs have to do with weight loss?

An odd series of clinical studies conducted over the past 40 years has demonstrated that foods can have opiate-like properties. Opiate blockers, like naloxone, can thereby block appetite. One such study demonstrated 28% reduction in caloric intake after naloxone administration. But opiate blocking drugs don't block desire for all foods, just some.

What food is known to be broken down into opiate-like polypeptides?

Wheat. On digestion in the gastrointestinal tract, wheat gluten is broken down into a collection of polypeptides that are released into the bloodstream. These gluten-derived polypeptides are able to cross the blood-brain barrier and enter the brain. Their binding to brain cells can be blocked by naloxone or naltrexone administration. These polypeptides have been named exorphins, since they exert morphine-like activity on the brain. While you may not be "high," many people experience a subtle reward, a low-grade pleasure or euphoria.

For the same reasons, 30% of people who stop consuming wheat experience withdrawal, i.e., sadness, mental fog, and fatigue.

Wouldn't you know that the pharmaceutical industry would eventually catch on? Drug company startup, Orexigen, will be making FDA application for its drug, Contrave, a combination of naltrexone and the antidepressant, buproprion. It is billed as a blocker of the "mesolimbic reward system" that enhances weight loss.

Step back a moment and think about this: We are urged by the USDA and other "official" sources of nutritional advice to eat more "healthy whole grains." Such advice creates a nation of obese Americans, many the unwitting victims of the new generation of exorphin-generating, high-yield dwarf mutant wheat. A desperate, obese public now turns to the drug industry to provide drugs that can turn off the addictive behavior of the USDA-endorsed food.

There is no question that wheat has addictive properties. You will soon be able to take a drug to block its effects. That way, the food industry profits, the drug industry profits, and you pay for it all.

Heart scan tomfoolery 2

9. November 2010 William Davis (2)

In the last Heart Scan Blog post, I discussed the significance of the apparent discrepancy between Steve's heart scan score and volume score. This post addresses his second question, also a FAQ about heart scan scores.

Steve noted that his second scan compared to his first showed:

- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

So there are apparent divergences in behavior in the left main that increased and both LAD (left anterior descending) and LCX (left circumflex) that decreased.

The explanation is simple: When heart scans are "scored," they are viewed in horizontal "slices." When the heart is viewed as horizontal slices, the LAD and LCX originate from the common left main stem. In other words, it's like a tree with the left mainsteam representing the trunk, the LAD and LCX representing two main branches.

Plaque can form, obviously, in all three arteries, but it can do so by starting in the left main, for instance, and extending into either the LAD or LCX, or both. The left main plaque can therefore bridge any 2 or all 3 arteries.

When the plaque is "scored" by taking the computer mouse and circling the calcified plaque in question (to allow the computer program to generate the calcium score and volume score of that particular plaque), the plaque that may extend from left main into the LAD and/or LCX might be labeled "left main," or it might be labeled "LAD" or "LCX." There is no reliable way to "dissect" apart the plaque into the three arteries, since the plaque is coalescent and continuous. So the scoring technologist or physician simply arbitrarily declares the artery "LAD," for instance.

The problem comes when two different interpretation methods are used: Perhaps it's a new technologist or physician, or there was no attention paid to how the previous scan was read. One reader calls it "left main" and the next calls it "LCX."

So the apparent discrepancy has to do with flaws in the methods of segregating plaque location, as well as inattention to scoring techniques. The total score, however, remains unaffected.

Nonetheless, Steve has enjoyed a modest reduction in the score of the left main/LAD/LCX from his original 140.8 down to a second left main/LAD/LCX score of 126.9.

The right coronary artery (RCA), however, is not subject to this difficulty and Steve score shows a modest increase in score. (Why the divergent behavior between left main/LAD/LCX and RCA? There is no clear explanation for this, unfortunately.)

All in all, the news for Steve is good: He achieved these results on his own using nutritional techniques. Because he, in all practicality, stopped the progression of his heart scan score and avoided the "natural" rate of increase of 30% per year, all he needs to do is "tweak" his program a bit to achieve reversal, i.e., reduction of score.

Here's an image from another previous Heart Scan Blog post (about the relationship of osteoporosis and coronary disease) that shows such a plaque that starts in the left mainstem yet extends into both the LAD and LCX:

Heart scan tomfoolery

4. November 2010 William Davis (12)

Heart Scan Blog reader, Steve, sent these interesting questions about his heart scan experience. (I sometimes forget that this blog is called "The Heart Scan Blog" and was originally--several years ago--meant to discuss heart scans. It has evolved to become a much broader conversation.)

The answers are a bit lengthy, so I'll tackle Steve's questions in two parts, the second in another blog post.

Dr. Davis,

I had a heart scan last year. The score was 96. While not a horrible score, it
was a wake up call, and I changed my lifestyle.

I had another scan this year and the heart scan score went up to 105, but the
volume score went down from 141 to 136.

The report I received said this:

'The calcium volume score is less in the current study as compared with the
original or reference study. This is an excellent coronary result and indicates
that there has been a net decrease in coronary plaque burden. The current
prevention program is very effective and should be continued.'

This is all well and good, but I have two questions:

1. Am I really going in the right direction even though the heart scan score
went up 9%?

2. Here are results that make no sense to me:
- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

Why would there be so much variation from year to year, and why would the plaque
move from site to site?

Steve

Questions like Steve's come up with some frequency, so I thought it would be worthwhile to discuss in a blog post.

First of all, the conventional heart scan score, or "calcium score" or "Agatston score" (after Dr. Arthur Agatston, developer of the simple algorithm for calcium scoring, as well as South Beach Diet fame), is the product of the area of the plaque in a single CT "slice" image
multiplied by a density coefficient, i.e., a number ranging from 1 to 4 that grades the x-ray density of the plaque. (1 is least dense; 4 is most dense.) A density coefficient of 1 therefore signifies some calcium within plaque, with higher density coefficients signifying increasing calcium content and density. Incidentally, "soft" plaque, i.e., non-calcified, would fall in the less than 1 range, even the negative range (fatty tissue within plaque).

The volume, or "volumetric," score is the brainchild of Drs. Paulo Raggi and Traci Callister, who expressed concern that, if we cause plaque to shrink in volume, the density coefficient used to calculate the calcium score would increase (since they believed that calcium could not be reduced, contrary to our Track Your Plaque experience, thereby leading to misleading results. They therefore developed an algorithm that did not rely on density coefficients, but used the same two-dimensional area obtained in the standard heart scan score, but replaced the density coefficient with a (mathematically interpolated) vertical axis (z-axis) measure of plaque "height." This 3-dimensional volumetric value therefore provided a method to generate a measure of calcium volume. In their original publication, the volume score proved more reproducible than the standard calcium score. This way, any reduction in plaque volume would not be influenced by the misleading effects of calcium density, but reflect a real reduction in volume.

Callister and Raggi's study also highlighted that calcium scoring in any form is subject to variability. Back in 1998 (when their study was published), there was a bit more variation than today due to the image acquisition methods used. But, even today, there is about 9% variation in scoring even if performed repeatedly (with less percentage variation the higher the score).

Unfortunately, volume scoring never caught on and the calcium score has been the most commonly used value by most heart scan centers and in most clinical studies. And, in all practicality, the two values nearly always track together: When calcium score increases, volume score increases in tandem; when calcium score decreases, volume score decreases in tandem.

Steve is therefore an exception to the general observation that calcium score and volume score travel together. Steve's calcium score increased, while his volume score decreased. From the above discussion, you can surmise a few things about Steve's experience:"

1) In all likelihood, the changes in both calcium score and volume score could simply be due to variability, i.e., variation in the placement of his body on the scan table, variation in position of the heart, variation in data acquisition, etc. There is a high likelihood that neither value changed; both are essentially unchanged.

2) If the changes are not due to scan variability, but are real, then it could be that the calcified plaque is reduced in volume but increased in density. If true, this is probably still a favorable phenomenon, since plaque volume is a powerful predictor of coronary "events" and an increase in plaque density is likely a benign phenomenon. It would also raise questions about the adequacy of vitamin D and vitamin K2 status, both major control factors over calcium deposition and metabolism.

So, in all likelihood, Steve's apparent discrepant results are modest good news, especially since calcium scores can ordinarily be expected to increase at the rate of 30% per year if no action is taken. Experiencing no change in score, calcium or volumetric, carries a very excellent prognosis, with risk for heart attack approaching zero. (I'm impressed that Steve accomplished this on his own, something the majority of my colleagues haven't the least bit of interest doing.)

Part 2 of Steve's question will be tackled in a separate post.

Can I see your linea alba?

2. November 2010 William Davis (19)

As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba.

Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen.

It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors.

Can you see your linea alba?

Dwarf mutant wheat

31. October 2010 William Davis (13)

Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.

Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant.

Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to.

The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans.

Medical education in the days of Big Pharma

30. October 2010 William Davis (43)

I received this detailed email from an unexpected source: a 3rd-year medical student.

In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life.

Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat.

While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career.

Dr. Davis,

I am a 3rd year medical student at ________ University. I came across
your blog today, and I'm very glad I did. I appreciate the value of your time,
so I want to be as succinct as possible while still getting across what I'm
really thinking and feeling:

From what I gathered exploring your blog for a while this afternoon, the
wellness strategies you incorporate into your practice are some of the exact
things I want to do with my future patients. Personally, I strongly believe in
staying healthy by eating right, staying active, etc. For instance, I don't eat
grains or much in the way of starches and sugars. So I love the fact that you
are helping your patients make these powerful and foundational changes in their
lives.

As I'm sure was your experience, a full appreciation of nutrition and lifestyle
as a first-line health strategy is not something that was taught to me in
medical school. I came to school with this deep conviction already in my heart
and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss
as to how I'm going to be able to practice medicine the way I want to, which is
to incorporate these all-important principles into the care of my patients.

What I've come to understand about the medical field today is that the
information that exists is primarily subsidized by the pharmaceutical industry,
and dictated to medical professionals as "evidence-based" treatment guidelines
and recommendations by organizations with sincere and official sounding names
like American Heart Association and American Cancer Society. Add to that the
pressure of potential malpractice litigation and the complexities of the
insurance reimbursement game, and it seems to me like what you get is a bunch of
diagnostic and medication management algorithms that any half-trained monkey
could follow. In his sleep. Which I guess would be alright if at least they
weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma,
Food Inc, insurance conglomerates, and agri-politics (I think I just made that
word up.)

A lot of well-intentioned physicians are just parroting the party
line, as their patients dutifully and gratefully chomp down their statins and
diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes
education" programs with curriculum put together by drug companies? How is that
even legal? Massive corporations raking in massive profits that are dependent
on uncontrolled blood sugars telling people how to best control their blood
sugars?!

Anyway, forgive my rant. What I'm getting at is this: How can I practice
medicine, with the freedom to educate/coach/treat my patients with diet and
lifestyle changes to mitigate/reverse their chronic health conditions? Without
feeling like I automatically have to first and foremost prescribe the litany of
drugs dictated by "evidence-based" guidelines? Without excessive fear of
litigation or loss of credibility among my peers? Without having to lie through
my teeth to my patients, and tell them that eating low-fat and heart-healthy
whole grains is the best way (implication also being the only scientifically
proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?

I want my patients to have the full benefit of honest nutrition and lifestyle
information, and medications and surgery as necessary. I'm afraid that there
isn't room for this kind of holistic emphasis in the medical profession today.
Are there residencies that include this kind of training or at least respect
these "unconventional" philosophies? Are there clinics or practice groups that
would allow me to practice with this emphasis, or is there a bias against docs
who do not necessarily conform to the party position? Will I have no other
option but to go it alone under the auspices of my own shingle? How do you
handle these kinds of issues in your professional life?

Sincerely,
Theresa M.

A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets.

I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often.

The Great Low-Carb Connector

28. October 2010 William Davis (15)

The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.

Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:

My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!

This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”

Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible.

New Track Your Plaque record!

27. October 2010 William Davis (19)

The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score.

Well, the longstanding record was broken this week: 75% reduction in score.

At the start, Freddie has disastrous lipid values:

LDL cholesterol 263 mg/dl
HDL 26 mg/dl
Triglycerides 323 mg/dl
Total cholesterol 354 mg/dl

Lipoproteins (NMR) were worse:

LDL particle number 3360 nmol/L
Small LDL 2677 nmol/L

Heart scan score: 732

Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable.

Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me.

Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight.

43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction.

While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees.

The Anti-AGEing Diet

22. October 2010 William Davis (36)

Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck.

There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others.

One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)

There are two general ways to develop AGEs:

1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months.

A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation.

2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi.

The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation.

Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food.

If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy.

The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs.

A curious case of coronary plaque regression and progression

18. September 2006 William Davis (0)

John received a coronary stent in 2003 following a small heart attack. The artery causing the heart attack was a diagonal artery, a branch of the important left anterior descending coronary artery (in the front of the heart). His cardiologist at the time advised him, "Take Lipitor and we'll do stress tests every year. Come back if you have any more chest pain." That was the full extent of John's preventive care.

He came to me for a second opinion and, naturally, we enrolled him in our program. We began by obtaining a CT heart scan score, though we had to exclude the stented diagonal artery. His score: 471. At age 51 and physically active, John had 7 additional abnormal lipoprotein patterns identified. We counseled John on better approaches to food choices, his weight target, fish oil, and correction of all lipoprotein patterns.

Two years later, John's repeat heart scan score: 511 . John was initially disappointed with the increase. But a closer look yielded something entirely different: the right coronary artery and circumflex (no stents) showed 20-30% reduction in their scores. The increase in total score was entirely due to substantial increase in score just outside the stent, in the left anterior descending artery. In other words, all of the increase in score was due to growth of a plaque at the mouth of the stent in the diagonal artery.

This is curious: profound regression of plaque with a big drop in score in the "un-instrumented" arteries, but tremendous growth of plaque and an increase in score in the "instrumented", or stented, artery, all in the same person's heart.

I don't know how controllable this specific situation in the left anterior descending and stented diagonal will be, and I'm unaware of any specific strategies to impact on this situation. The whole world of tissue growth within or around stents is littered with high hopes followed by failures. The drug-coated stents have been the only partial solution to this problem, though that's precisely the sort of stent John received.

Is there a message here? The message I take from this is that you and I should work like mad to keep from receiving a stent. Once they're implanted, we have less control over our coronary future. We can indeed regress ("reverse") coronary plaque. But we may not be able to regress the sort of tissue that grows in response to a stent implantation.

When is a heart scan score of 400 better than 200?

13. September 2006 William Davis (0)

Imagine two people.

Tom is a 50-year old man. Tom's initial heart scan score is 500--a bad score that carries a 5% or more risk for heart attack per year.

Harry is also 50 years old. His heart scan score is 100--also a concerning score but not with the same dangers of Tom's much higher score.

Tom follows a powerful heart disease prevention program like the Track Your Plaque program. He achieves the 60:60:60 lipid targets; chooses healthy foods; takes fish oil; raises his blood vitamin D level to >50 ng/ml, etc. One year later, Tom's heart scan score is 400, a 20% reduction from his starting score.

Harry, on the other hand, doesn't understand the implications of his score. Neither does his doctor. He's casually provided a prescription for a cholesterol drug by his doctor but nothing else. One year later, Harry's heart scan score is 200, a doubling (100% increase) of the original score.

At this point, we're left with Tom having a score of 400, Harry with a score of 200. That is, Tom has twice the score, or 200 points higher, compared to Harry. Who's better off?

Tom is better off. Even though he has a significantly higher score, Tom's plaque is regressing. It is therefore quiescent with its components being extracted, inflammation subsiding, the artery is in a more relaxed state, etc.

Harry's plaque, in contrast, is active and growing: inflammatory cells are abundant and producing enzymes that degrade supportive tissue, excessive constrictive factors are constantly causing the artery to pinch partially closed, fatty materials are accumulating and triggering a cascade of abnormal responses.

This is therefore a peculiar situation in which a higher score is actually better than a lower score. It reflects the power of adhering to a preventive program. It also demonstrates how two scans are better than one because they show the rate of increase given a particular preventive approach.

Warning: Your cardiologist may be dangerous to your health!

12. September 2006 William Davis (1)

Warren had a moderately high LDL cholesterol for years and took a statin drug sporadically over the past 7 years. Finally retired from a successful real estate investment business, he had a CT heart scan to assess his heart disease status.

Warren's score: 49. At age 59, this put him in the lowest 25%, with an estimated heart attack risk of 1% per year or less--a relatively low risk. At this heart scan score, the likelihood of an abnormal stress test was less than 3%, or a 97% likelihood of a normal stress test. Most would argue that a stress test would be unproductive, given its low probability of yielding useful information. In other words, there would be a 97% probability of normal blood flow through Warren's coronary plaque, and less than 3% likelihood that a stent or bypass surgery would be necessary.

Warren was also without symptoms. He hiked and biked without any chest discomfort or breathlessness. A prevention program like Track Your Plaque to gain control over future coronary plaque growth was all that was necessary and Warren had high hopes for a life free of heart attack and major heart procedures.

Then why did he go through a heart catheterization?

Warren did indeed undergo a heart catheterization on the advice of his cardiologist. When I met Warren for another opinion, it became immediately obvious that the heart catheterization was completely unnecessary. Then why was this invasive procedure done? There can only be a few reasons:

--The cardiologist didn't truly understand the meaning of the heart scan score. "We need to do a 'real' test."

--The cardiologist was terrified of malpractice risk for underdiagnosing or undertreating any condition, no matter how mild.

--The cardiologist wanted to make more money. Talking about heart disease prevention is a money-saving, not a money-making, approach.

Regardless of which of the three motivations was at work here, they're all inexcusable. A disservice was done to this man: he had an unnecessary procedure, incurred some risk of complication in the process, and gained nothing.

An ignorant or profit-seeking cardiologist is worse than the unscrupulous car mechanic who, when presented with an unknowing car repair customer, proceeds to replace the carburetor and rebuild the engine when a simple 5-minute adjustment would have taken care of the problem.

I estimate that no more than 10% of my colleagues follow such practices, but it's often hard to know who is in that 10%. Ask pointed questions: Why is the catheterization necessary? What is the likelihood of finding information useful to my health? What are the alternatives? (By the way, the emerging CT coronary angiograms can be a useful alternative in some situations like this.)

I don’t have high blood pressure!

12. September 2006 William Davis (0)

Art undeniably had high blood pressure.

At age 53, he had all the “footprints” of high blood pressure that’d been present for at least several years: abnormal patterns by EKG, abnormally thick heart muscle, and an enlarged aorta by an echocardiogram. These sorts of changes require many years to develop. Art’s blood pressure was 140/85 sitting quietly in the office.

“That’s about what my primary care doc gets, too. Whenever it’s high, he takes it again after a few minutes and it always comes down.”

Art tried to persuade me that his blood pressure was high today only because of the traffic on the way into the office. When I dismissed this as a cause, he insisted that stress he’d been suffering because of his teenage son was the cause. “I just know I don’t have high blood pressure!”

Who’s right here? Well, Art is not here to defend himself. But one fact is crystal clear: you cannot develop complications of high blood pressure unless you truly have high blood pressure!

In other words, Art’s abnormal changes in heart structure (thickened heart muscle and enlarged aorta) are serious changes that develop only with years and years of sustained blood pressure at least as high as the one in the office. His blood pressure almost certainly ranged much higher at other times, particularly during stressful situations like waiting in the check-out line at the grocery store, watching a suspenseful TV show, petty irritations at his job, and on and on.

Blood pressure does not have to be high all the time to generate complications of high blood pressure. It can be sporadic, variable, even occasional. Clearly, sustained high blood pressure is the worst situation that creates adverse consequences more quickly. But blood pressure that wavers from low to high only some of the time can still, given sufficient time, cause the very same unwanted effects.

Control of blood pressure is crucial to your coronary plaque control program. Blood pressure may be boring: not as exotic, say, as lipoproteins, and not as fun as talking about nutritional supplements. But neglect blood pressure issues and you will not gain full control over coronary plaque growth—-your heart scan score will increase.

Watch for an upcoming Special Report on the Track Your Plaque Membership website, a full detailed discussion of how to recognize when blood pressure is an important issue, along with a full discussion of nutritional methods to reduce it, often sufficient to minimize or eliminate the need for medication.

Are there any alternatives to niacin?

10. September 2006 William Davis (0)

In the Track Your Plaque program, we tend to rely a great deal on niacin. When used properly, 90-95% of people will do just fine and achieve their lipid and lipoprotein goals with the help of niacin, along with their other efforts.

Unfortunately, around 5% of people simply can't take niacin without intolerable "hot flush" effects, or occasionally excessive skin sensitivity--itching, burning, etc.

Why does this happen? These 5% tend to be "rapid metabolizers" of niacin, i.e. they convert niacin (nicotinic acid, or vitamin B3) into a metabolite called nicotinuric acid. Nicotinuric acid is the compound responsible for the skin flush. Most people can slow or reduce the effects of nicotinuric acid by:

--Taking niacin with dinner, so that food slow tablet dissolution.

--Taking with plenty of water. Two 8-12 oz glasses usually eliminates the flush entirely in most people.

--Taking with an uncoated 325 mg tablet of aspirin in the first few weeks or months. Eventually, you will need to revert back to a better stomach tolerated dose of 81 mg, preferably enteric coated. But a full 325 mg uncoated can really help in the beginning, or when you have any niacin dose increases, e.g., 500 mg to 1000 mg.

But even with these very effective strategies, some people still struggle. That's when the question arises: Are there any alternatives to niacin?

Well, it depends on why niacin is being used. If you and your doctor are using niacin for:

Raising HDL--Then weight loss to your ideal weight; reduction of processed carbohydrates, especially wheat products; avoidance of hydrogenated ("trans") fats; a glass or two of red wine per day; dark chocolates (make sure first ingredient is chocolate or cocoa, not sugar), 40 gm per day; fish oil; exercise; other prescription agents (fibrates like Tricor; TZD agents for diabetes; cilostazol (Pletal)). Niacin is by far the most effective agent of all, but, if you're intolerant, raising HDL is still possible through a multi-faceted effort.

Reduction of small LDL--The list of effective strategies is the same as for raising HDL, but add raw almonds (1/4-1/2 cup per day), oat bran and other beta-glucan rich foods like oatmeal. Reduction of processed carbohydrates is especially important to reduce small LDL.

Reduction of Lipoprotein(a)--This is a tricky one. For men, testosterone and DHEA are effective alternatives; for women, estrogen and perhaps DHEA. Hormonal preparations of testosterone and estrogen are stricly prescription; DHEA is OTC. I have not seen the outsized benefits on lipoprotein(a) claimed by Rath et al by using high-dose vitamin C, lysine, and profile, unfortunately. We are clearly in need of better alternatives to treat this difficult and high-risk disorder.

Reduction of triglycerides/VLDL/IDL--I lump these three together since they all respond together. If you're niacin intolerant, maximixing your fish oil can be crucial for reduction of these patterns using doses above the usual starting 4000 mg per day (providing 1200 mg EPA+DHA). Reduction of processed carbohydrates, eimination of processed foods that contain high-fructose corn syrup, and weight loss to ideal weight are also very effective. "Soft" strategies with modest effects include green tea (>6 cups per day) or theaflavin 600-900 mg/day; raw nuts like almonds, walnuts, and pecans; exercise; soy protein.

Reduction of LDL--Lots of alternatives here including oat bran (3 tbsp per day), ground flaxseed (3 tbsp per day), soy protein (25 grams per day), Benecol butter substitute (for stanol esters), soluble fibers like pectin, psyllium, glucomannan; raw nuts like almonds, walnuts, and pecans.

In future, should torcetrapib become available (by prescription), this will add to our available tools for these areas when niacin can't be used. Until now, the alternatives to niacin depend on what you and your doctor are trying to achieve. In the vast majority of cases, HDL, small LDL, triglyceride, etc. goals for heart scan score control can be achieved, even when niacin is not well tolerated.

Is flaxseed oil a substitute for fish oil?

9. September 2006 William Davis (3)

This question comes up so frequently that it's worth going over.

Flaxseed oil is a wonderful oil rich in linolenic acid, which may provide health benefits all by itself. Some authorities have speculated that the substantial reduction in heart attack seen in the Lyon Heart Study, the study that demonstrated the healthy power of the Mediterranean diet, is due to linolenic acid.

Flaxseed oil is also rich in monounsaturates and low in saturates, both desirable qualities. Of course, I'm talking here about flaxseed oil, to be distinguished from flaxseed , which are the intact seeds. The seeds themselves also contain the same oils, but contain other components, specifically lignan, a plant fiber with suspected health benefits like reduction in cancer risk.

Despite all flaxseed oil's wonderful properties, it is definitely not a substitute for fish oil. Why do we use fish oil for our coronary plaque control program (trying to reduce your heart scan score)? Several reasons. Fish oil:

--Dramatically reduces triglycerides, usually by 50% or more.
--Dramatically reduces specific lipoprotein classes like VLDL
--Dramatatically reduces, often eliminates, abnormal postprandial (after-eating) lipoprotein patterns, like IDL (intermediate-density lipoprotein)
--Has been conclusively shown to reduce risk of heart attack and death from heart attack (GISSI Prevenzione Trial).
--Has been shwon to reduce risk of stroke.
--Modifies blood clotting parameters, particularly a 20% reduction in fibrinogen.

Flaxseed oil, or linolenic acid concentrate for that matter, do not accomplish any of these effects, all crucial if you are to gain control over your coronary plaque.

Flaxseed oil and flaxseed remain wonderful nutritional agents for their own reasons. But they will not substitute for fish oil in your program. Only fish oil--the real thing--does the job.

If you have coronary artery disease . . . do you know why?

9. September 2006 William Davis (0)

This conversation is aimed primarily at non-followers of the Track Your Plaque program, because if you were a follower, you’d already know the answer!

I saw a woman in the hospital today. She’d just survived her second heart attack one week earlier. At 51 years old, she was understandably shaken, perhaps terrified. She felt that her future was uncertain and, in fact, had discussed with her husband what he should do to prepare for a future without her.

One week earlier, she’d received three stents that successfully aborted her heart attack. But, as is always the case, the modest delays of ambulance transport, the emergency room preliminaries, then of mobilizing an available cardiologist and catheterization laboratory team, totaled nearly two hours before her stent procedure. Inevitably, a moderate amount of damage had been done to her heart.

Her first “event” had been very similar: very little warning, then 911 and the flurry of activity. Both times, the cardiologists (two different physicians) complimented the patient on her prompt action. Both also called her heart attacks “close calls”.

She defied the odds with two near-death events. So, when I met her a week after her last heart attack, I asked an obvious question: “Has anyone told you why you’re having these heart attacks?”

She looked completely puzzled at first. She then said, “No, not really. I just assumed it was genetic. My mother went through the same thing when she was my age. But she didn’t get as far as I have, since they didn’t have these procedures back then.”

To me, this seems inexcusable: This woman had experienced two brushes with death and no doctor had established a cause. Could this woman’s belief be true, that it’s just genetic?

While there are, indeed, genetic causes for heart disease, the vast majority of these genetic causes are 1) identifiable, and 2) correctable. Genetic does not necessarily mean hopeless. It just means that the usual equation of heart disease risk management (heart disease = LDL cholesterol = need for Lipitor) has limited value. It would be like giving penicillin to people for any and all infections. It will work occasionally, but it will fail miserably in a great many cases. Treating LDL cholesterol with statin drugs is just like that.

Perhaps this woman has lipoprotein(a), a serious genetic trait that predicts heart disease at a young age and is largely unaffected by statin drugs. Or, she may have a severe excess of small LDL, only partially suppressed by statins. If she has the combined pattern of lipoprotein(a) and small LDL, that means she has two statin-unresponsive and significant genetic traits. But they respond to niacin, specific nutritional strategies, and several other agents.

The message: If you have coronary disease, you need to insist on knowing why. “It’s genetic” is not an acceptable answer. “There’s no proof of any heart disease causes beyond cholesterol” is also nonsense. “Everyone gets heart disease, or “hardening of the arteries”, eventually. You just got it a little before everyone else” is also patently ridiculous.

Identifying the causes of your coronary disease (or coronary plaque if you’ve had a CT heart scan) is the first step in developing a program of treatment that provides you with control over this disease.

Have you tried inulin yet?

8. September 2006 William Davis (0)

If you haven't yet tried it to facilitate weight loss, it's really worth giving the new inulin-containing product, Fiber Choice "Weight Management", a try.

Recall (from a prior Heart Scan Blog) that inulin is a vegetable-based fiber found in celery, green peppers, etc. that, when exposed to water, expands to many times original volume. This simple phenomenon yields satiety--a feeling of fullness.

The manufacturer of the product has also added green tea, which has been shown in two small clinical studies to enhance weight loss, though by a different route.

We've been advising patients to chew two of the strawberry flavored tablets one hour before every meal (or with breakfast if you eat immediately in the morning). You'll be satisfied with less food and you'll experience less intense food cravings.

Though no one so far has achieved a huge drop in weight, it does seem to enhance a slow, gradual weight loss larger than achieved by diet and exercise alone. And it's very safe and inexpensive. If you give it a try to help you lose weight, let us know what kind of results you've obtained.

More on Vitamin D

If you haven't done so already, you should subscribe to Dr. John Cannell's free newsletter on vitamin D issues. His newest issue is available at:

A sign-up to subscribe is available on the same page.

I continue to be shocked and amazed at the prevalence and magnitude of vitamin D deficiency in the people I see every day. It's been a beautiful summer with very little rain. Most days have been in the 70-80 degree range--very comfortable to be outdoors in the sun and getting skin expoxure to activate vitamin D in the skin.

Yet, in the vast majority of people I see, summer blood levels of vitamin D are virtually indistinguishable from winter levels. Both hover around the 30 ng/ml range. Summer levels in Wisconsin people seem to be no more than 10 ng/ml higher than winter levels. This remains true even in people who spend a lot of their day outdoors gardening, walking, etc. wearing shorts and a short-sleeved shirt, i.e. with plenty of skin surface area exposed.

I'm at a loss to explain precisely why. Yes, it is Wisconsin. But a direct sun overhead, 75 degree day should be providing plenty of sun. My suspicious is that a combination of factors are at work: people are not spending as much time outdoors as they claim; they often seek shade; use sunscreen; and they're overweight. (Excess weight decreases vitamin D blood levels dramatically, yet another reason not to get fat!)
