Estrogens and CT heart scan scores

2. July 2007 William Davis (1)

A recent study from the Women's Health Initiative (WHI), the large study that originally showed no reduction in heart attack with use of estrogens in postmenopausal females, has just published a new study.

In this new effort, women who took Premarin (horse estogens) had up to 61% lower CT heart scan scores. This new study was confined to the women from the original WHI study who had entered the study between the ages of 50-59 years (average 55 years old), since this was the significant subgroup of women who actually showed a reduction in heart attack risk, whereas other groups showed no benefit or a slightly increased risk.

For a full discussion of this fascinating result, see the Track Your Plaque report, Can estrogen reduce CT heart scan scores? at http://cureality.com/library/fl_06-017estrogen.asp. (This report is open to both Track Your Plaque Members and non-Members.)

I truly wish that the issues surrounding female hormone replacement were clearer. This new perspective adds just another interesting twist on a strategy that too many people, in my view, dismissed too readily with the initial WHI results.

To add to an already confusing situation, the WHI study was sponsored by Wyeth Pharmaceuticals, the maker of Premarin, and many of the investigators participating in the study obtained financial compensation from Wyeth. On the one hand, we have to give credit to the company and the investigators for publishing the initial study that panned the effects of Premarin. On the other hand, it makes any positive data somewhat suspect, particularly since there is a far less costly and probably superior preparation called human estrogens.

Incidentally, Wyeth is also behind the maddening FDA petition to prevent "compounding" pharmacies from dispensing human hormones like estrogen unless made by a drug manufacturer. They hide behind claims of concerns over safety. Nonsense. This is pure profiteering and protection of their enormously profitable franchise and has nothing to do with public safety. If there were genuine concerns that the compounding pharmacies, around for decades with an excellent reputation, pose safety issues, why not just lobby for improved oversite?

If only we had data like WHI that used human estrogens and human progesterone. I suspect that we'd see bigger, better effects with less of the ill effects peculiar to the cross-species use of Premarin and the synethetic progestin, Provera.

The wheat-free life

30. June 2007 William Davis (10)

"There's nothing else I can do with my diet," declared Whitney, a 53-year old university faculty member.

"I don't eat meat. I never eat fried foods. I can't remember the last time I used butter. My idea of having a treat is a handful of blueberries. What else can I do?"

Whitney was clearly frustrated. With a CT heart scan score of 264, she was worried that trouble was just around the corner. Her lipoprotein panel had demonstrated a severe small LDL pattern, with 70% of all LDL particles in the small category. HDL was also low at 41 mg/dl.

"What did you eat for breakfast?" I asked.

"Same as always: Either Fiber One cereal or Shredded Wheat. No sugar, just skim milk. Sometimes I have some orange juice, fresh-squeezed of course."

"How about lunch?"

"If I brown-bag it, I'll usually have a reduced-fat turkey breast sandwich on whole grain bread. About once a week, I'll have a whole wheat bagel--no cream cheese, of course."

"Dinner?"

"Sometimes I have chicken--skinless--with a vegetable, corn, or salad. I love pasta, but I always use whole wheat."

"How about snacks?"

"I try not to snack. But, when I'm desperate, I usually grab some Triscuits or pretzels."

The problem with Whitney's diet was clear: Too many sugar-equivalents, otherwise known as wheat. I suggested that her diet was far too heavily laden with wheat products. She seemed skeptical. "But this is as low-fat as I can get! Now you're going to take away wheat?"

What happens when you eliminate wheat from your diet?

Several predictable, consistent changes can be observed:

--HDL cholesterol goes up.

--Triglycerides go down.

--Small LDL particles are reduced.

--LDL cholesterol drops (the amount dropped depends on the proportion of small LDL pattern)

--Blood sugar drops.

--Blood pressure drops.

--C-reactive protein (an index of imperceptible inflammation) drops.

In addition to these measurable changes, several perceptible improvements often develop: more energy, less afternoon "slump," better sleep, sometimes less rashes.

Since Whitney was skeptical, I suggested a simple 4 week "experiment": Eliminate wheat products entirely for 4 weeks and see for herself what happens. I also warned her that, while I believe that elimination of wheat is a great strategy, she could negate the benefits by indulging in candy, soft drinks, and other junk products. It would therefore be necessary to maintain an otherwise healthy diet.

So Whitney gave it a try for 4 weeks. To make up for the dropped calories, she increased her reliance on vegetables, fruits, lean proteins, nuts, seeds, and healthy oils.

After losing 6 lbs over the 4 weeks without otherwise trying, she was convinced. She was further convinced when we reassessed her laboratory work: HDL went up 10 mg/dl; triglycerides down 120 mg/dl; blood sugar dropped from 112 mg/dl (pre-diabetic) to 95 mg/dl (normal). Several months later, we checked her lipoproteins. Small LDL had dropped to around 30% of total LDL--a big improvement.

It's contrary to conventional wisdom. It's counter to the USDA Food Pyramid. It's certainly not what the American Heart Association says. It could potentially disrupt the economics and politics of the enormously powerful food industry.

But, more often than not, the results are impressive to phenomenal.

Death of a $7 billion industry

28. June 2007 William Davis (8)

Vitamin D has taken its place as a crucial ingredient for coronary plaque control and control of CT heart scan scores.

Vitamin D replacement is also crucial for bone health, particularly the prevention of osteoporosis. But conversations about vitamin D replacement to true healthy levels is notably absent from the conversation on treatment and prevention of osteoporosis. Yes, you will find a small dose of vitamin D in calcium tablets and in multivitamins. Those of us who check blood levels of 25-OH-vitamin D3 in patients will tell you: They don't work. These are unabsorbable forms of vitamin D and at trivial doses. There was an attempt to give this issue a little cursory attention when a small dose of vitamin D was added to Fosamax (Fosamax D).

There are an estimated 50 million Americans with various degrees of osteoporosis. It's numbers like this that make the drug manufacturers salivate. Osteoporosis treatment is also chronic. This is among the holy grails of the drug industry: developing agents for widespread ailments that require long-term treatment that extends over years. That's a lot more profitable than 10 days of antibiotics that are over and done with in one treament course.

The osteoporosis market now stands at $7 billion per year and is expected to grow 6-7% per year, according to industry analysts. Drugs like Fosamax, Evista, and Actonel will eventually be replaced by Boniva, Eclasta, and bazedoxifene, and later by AMG-172 and balicatib. Monthly costs for these drugs can be $70 or more per month, sometimes several hundred dollars. (Experience has shown that the introduction of new drugs does not necessarily mean that other drugs will drop in price.)

Here's a clinical trial I'd like to see performed: Vitamin D restored to healthy levels of 50-100 ng/ml over an extended period and compared to a group treated with placebo. My prediction is that there will be dramatic differences in bone density. (Small studies have been performed, but no large, long-term trials of the sort that would yield real firepower.) Or, how about vitamin D to true therapeutic levels over 5 years compared head-to-head with one of the drugs. My prediction: little difference.

Vitamin D also provides an enormous panel of health benefits beyond restoration of bone density, like rise in HDL, drop in triglycerides, facilitation of control over CT heart scan scores, drop in fracture risk, drop in blood pressure and C-reactive protein, reduction in risk for colon, prostate, and breast cancer. None of the drugs can hope to provide any of these effects, except a drop in fracture risk.

Vitamin D usually costs around $2 per month. I doubt that such trials will be performed. If I were a manufacturer of osteoporosis drugs and my career success was dependent on the increasing revenues of these drugs, I would be quaking in my shoes, hoping that the public does not learn what a powerful tool good old vitamin D is. But if you are an individual just looking for health tools, vitamin D is, in my view, amongst the most powerful natural, nutritional tools you have available with outsized health benefits.

Lose weight and HDL goes . . . down

27. June 2007 William Davis (2)

Steve started with a miserable HDL cholesterol of 27 mg/dl. As expected, the low HDL was associated with all its evil friends: small LDL, deficiency of healthy, large HDL, high triglycerides, VLDL, and a pre-diabetic blood sugar.

Steve committed to a strict diet of reduced processed carbohydrates like wheat products, reduced meat and saturated fats. He relied on vegetables, fruit, lean proteins, and healthy oils. Over a 6 month period, he lost an impressive 39 lbs. He proclaimed that he hadn't felt this good in 30 years.

We rechecked his HDL: 25 mg/dl.

"I don't get it!" Steve declared, understandably.

There's a curious phenomenon with HDL. If you lose weight, HDL goes up--but not right away. Steve had lost a substantial quantity of weight and was continuing to lose weight when the blood work was obtained. While HDL does indeed rise with weight loss, it doesn't do so immediately. In fact, in the first two or so months after significant weight lost, HDL goes down.

Why? I don't really have an explanation, but it is a very consistent effect.

Losing weight towards ideal weight is truly an effective strategy for raising HDL. But we need to be patient. If you've lost many pounds like Steve did, then waiting at least two months after weight has stabilized may be necessary to fully gauge the effect on raising HDL.

Addictive Foods

25. June 2007 William Davis (3)

Kraft Foods, Inc. is manufacturer of Kool Aid, Oscar Mayer, Kraft Macaroni and Cheese, Velveeta, Honey Maid Grahams, and hundreds of other processed food products. Post cereals also falls under the umbrella of Kraft with products like Raisin Bran, Post Toasties, and Fruity Pebbles. Annual revenues in 2006 for Kraft: $34.4 billion. A big operation with enormous influence over our eating habits.

Nabisco is manufacturer of Oreos, Ritz Crackers, Chips Ahoy and many others. Like Kraft/Post, it is also a big player.

While Nabisco was owned for several years by tobacco giant RJ Reynolds, in 2000 it was acquired by Philip Morris, another big tobacco manufacturer.

More recently in Spring, 2007, Philip Morris (now called Altria--you'd change your name, too, if it was synonymous with dirt) spun off its Kraft subsidiary for a big profit. However, the management structures remain intertwined.

In other words, despite the shuffling of shares, the two industries, big tobacco and big food, are in many respects one and the same.

Is it any surprise that the same industry that made billions of dollars pushing addictive nicotine products responsible for the deaths of hundreds of thousands of people is now intimately involved with addictive products produced and marketed by the processed food industry?

If you believe that food manufacturers are innocently and honestly conducting their businesses, simply think back to the testimony provided in front of Congress during the tobacco industry hearings. Broad deception, concealed truths, and outright lies were commonplace. There was no conscience involved. This was about money--and lots of it.

Why should the processed food industry, intimate with the tobacco industry, be any different?

If you want control over heart disease and your heart scan score, buy produce and buy local. Spend your time in the produce aisle, not the cereal or chip aisle. Unprocessed food, unadorned by bright labels, cartoon animals, American Heart Association endorsements, that's what we should seek.

Heart Scan Curiosities #7

25. June 2007 William Davis (1)

Here's a situation that crops up once in a while, occurring in perhaps 2% of heart scans.

The white within the circled area represents calcium, and thereby atherosclerotic plaque, situated immediately at the "mouth", or opening, of the the right coronary artery. What is somewhat unusual is that this plaque is not principally coronary, but aortic. That is, the plaque is mostly situated in the large vessel called the aorta. The three coronary arteries arise from the aorta.

In this instance, the aortic plaque involves the mouth of the right coronary artery. (In views not shown, the plaque also extends into the artery as well.) I call this a "double whammy" because the same plaque can post risk for heart attack and stroke.

Generally, aortic plaques pose risk for stroke. When aortic plaque fragments, little bits and pieces can travel upward to the brain and block an artery, thus a stroke.

In the coronaries, disrupted ("ruptured") plaques don't generally shower debris, but permit blood clot formation, resulting in heart attack.

This plaque, however, poses the theoretical risk of both heart attack and stroke because of its strategic location.

Should a plaque like this be handled any differently? I don't think so. But it does provide another reason to take atherosclerotic plaque in any artery seriously.

The nutrition counterculture

23. June 2007 William Davis (2)

When we look back over our American nutritional history over the last 50 years, it's hard not to come to the conclusion that much of the innovation in nutrition did not come from official agencies like the Food and Nutrition Board of the Institute of Medicine, the National Academy of Sciences, the FDA, the USDA, or the AMA.

Instead, it came from the popular culture. It came from bold, extravagant claims made by maverick figures like Ancel Keys, Nathan Pritikin, Dean Ornish, and Robert Atkins. Of course, some ideas have now fallen by the wayside, dismissed in a broad American "experiment" as ineffective, impractical, or kooky. But it permitted experimentation on an extraordinary scale with millions of people following a particular strategy at a time.

The advice of the official agencies tended to be reactionary. When nutritional deficiencies (remember those?) of the early 1900s were prevalent, they issued advice on food choices to help alleviate deficiencies. When deficiency transformed into excess after World War II, "smart" food choices from food groups and "sensible eating" became the theme.

Unfortunately, the advice was always adulterated by the enormous influence of various special interests, anxious to protect their national franchise. Powerful groups like the meat industry, wheat producers, and the dairy industry all made sure they had a big hand in crafting and influencing what was told to the American people.

The result: the advice offered by official groups has always represented the compromise of what some agency wished to convey to the people and the very powerful input of industry. What if the government decided to advise us what automobile to buy? Imagine the uproar in the auto industry when Washington tells us to buy Toyota for fuel economy and reliability. How long would that advice last?

That's why almost no knowledgeable adult follows the advice of the USDA, the National Academy of Sciences, or the Food Pyramid. I believe that we all intuitively recognize that the advice is watered-down, sometimes silly, sometimes downright unhealthy.

Nonetheless, the national experiment in diet that has taken place since 1950 has led to a collective wisdom of what is good and what is bad. The most productive conversations on nutrition therefore take place outside of the USDA and Washington. It occurs, instead, in places like bookstores, websites, and the media. Of course, there's lots of misinformation and profiteering in these sectors, as well. But like the enormous force unleashed by the collective wisdom of those contributing to the Wikipedia phemonenon, we've zig-zagged to something closer to the truth than ever uttered by an official agency.

Prescription vitamin D

23. June 2007 William Davis (32)

Niacin:

Over-the-counter: $2-5 per month
Prescription: $120 per month

Fish oil:

Over-the-counter: $3-6 per month
Prescription: $120 per month

Vitamin D:

Over-the-counter: $2 per month
Prescription: $70 per month

With vitamin D in particular, the prescription form is vastly inferior to the over-the-counter preparation. This is because the prescription form is ergocalciferol, or vitamin D2, not the effective human form, vitamin D3 or cholecalciferol.

When you're exposed to sun, what form of vitamin D is activated in the skin? It's all vitamin D3, no vitamin D2 whatsoever. Vitamin D3 is also far more effective than D2. People taking D3 (as long as it's oil-based) easily obtain healthy levels of vitamin D in the blood. People taking 50,000 units per day of D2 (the recommended quantity) remain miserably deficient, with minor increases in vitamin D blood levels. In short, D2 barely works at all. D3 works easily and effectively.

Moreover, D2 is the plant-based form. It is a form not found naturally in humans. D3 is the mammalian form, the same found in humans that exerts all its biologic benefits.

Then why is the prescription form of vitamin D2 (brand names Driscol and Calciferol) more expensive?

It's the same old pharmaceutical industry scam: Look for something patent protectable, regardless of whether it's superior to the non-patent protectable product, then sell it for exagerated profits. Though it is inferior and the science and clinical experience prove that it's inferior, you can still fool lots of people, including prescribing physicians. So what if you only make $50 or $100 million?

Don't fall for it. Prescription doesn't necessarily mean superior. In fact, the prescription form may be significantly inferior, as with vitamin D2. But the pharmaceutical industry carries such power and persuasion, who's going to know?

Nutrition activist Mike Adams

20. June 2007 William Davis (1)

I borrowed the above comic from the website of nutritionist, more properly nutrition activist and author, Mike Adams. His website, www.newstarget.com, was a pleasant surprise.

I was actually looking for some thoughts on pharmaceutical advertising and its pervasive and destructive effects and came across one of Adam's reports, Pharmaceutical television advertising is a grand hoax at http://www.newstarget.com/021526.html. The piece is a rant against the pharmaceutical industry's constant bombardment of the media, who have also been co-opted into their service, enticed by the enormous advertising revenues the drug industry brings.

But I was surprised to find an insightful, informative website on health issues, particularly healthy eating that rejects the manufactured food industry's intensive effort to persuade us to eat their products. While I don't agree with everything Adams has to say, his website provides some great food for thought. He also provides lots of downloadable information.

There's also some great laughs at his poke at the pharmaceutical industry with his Disease Mongering Engine at http://www.newstarget.com/disease-mongering-engine.asp, in which you get to create your own diseases. I got a real kick out of this.

CT scans and radiation exposure

19. June 2007 William Davis (8)

The NY Times ran an article called

With Rise in Radiation Exposure, Experts Urge Caution on Tests at

http://www.nytimes.com/2007/06/19/health/19cons.html?_r=1&adxnnl=1&oref=slogin&adxnnlx=1182254102-vQpytpx6W/Z9gvAaNPDZvA

“This is an absolutely sentinel event, a wake-up call,” said Dr. Fred A. Mettler Jr., principal investigator for the study, by the National Council on Radiation Protection. “Medical exposure now dwarfs that of all other sources.”

Where do CT heart scans fall?

Let's first take a look at exposure measured for different sorts of tests:

Typical effective radiation dose values

Computed tomography Milliseverts (mSv)

Head CT 1 – 2 mSv
Pelvis CT 3 – 4 mSv
Chest CT 5 – 7 mSv
Abdomen CT 5 – 7 mSv
Abdomen/pelvis CT 8 – 11 mSv
Coronary CT angiography 5 – 12 mSv

Non-CT Milliseverts (mSv)

Hand radiograph Less than 0.1 mSv
Chest radiograph Less than 0.1 mSv
Mammogram 0.3 – 0.6 mSv
Barium enema exam 3 – 6 mSv
Coronary angiogram 5 – 10 mSv
Sestamibi myocardial perfusion (per injection) 6 – 9 mSv
Thallium myocardial perfusion (per injection) 26 – 35 mSv

Source: Cynthia H. McCullough, Ph.D., Mayo Clinic, Rochester, MN

If you have a heart scan on an EBT device, then your exposure is 0.5-0.6 mSv, roughly the same as a mammogram or several standard chest x-rays.

A heart scan on a 16- or 64-slice multidetector device, your exposure is around 1.0-2.0 mSv, about the same as 2-3 mammograms, though dose can vary with this technology depending on how it is performed (gated to the EKG, device settings, etc.)

CT coronary angiography presents a different story. This is where radiation really escalates and puts the radiation exposure issue in the spotlight. As Dr. Cynthia McCullough's chart shows above, the radiation exposure with CT coronary angiograms is 5-12 mSv, the equivalent of 100 chest x-rays or 20 mammograms. Now that's a problem.

The exposure is about the same for a pelvic or abdominal CT. The problem is that some centers are using CT coronary angiograms as screening procedures and even advocating their use annually. This is where the alarm needs to be sounded. These tests, as wonderful as the information and image quality can be, are not screening tests. Just like a pelvic CT, they are diagnostic tests done for legimate medical questions. They are not screening tests to be applied broadly and used year after year.

Always be mindful of your radiation exposure, as the NY Times article rightly advises. However, don't be so frightened that you are kept from obtaining truly useful information from, for instance, a CT heart scan (not angiography) at a modest radiation cost.

Detail on radiation exposure with CT coronary angiograms on multidetector devices can be found at Hausleiter J, Meyer T, Hadamitzyky M et al. Radiation Dose Estimates From Cardiac Multislice Computed Tomography in Daily Practice: Impact of Different Scanning Protocols on Effective Dose Estimates. Circulation 2006;113:1305-1310, one of several studies on this issue.

Wheat belly

23. July 2007 William Davis (31)

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.

(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

If health won't motivate them, maybe money will

23. July 2007 William Davis (0)

As part of our ongoing effort to educate everyone about the value of heart scans and how they can serve to start a program of heart disease prevention (or elimination), we occasionally distribute press releases on one facet of this discussion or another.

Here's the one we released on our Cost Calculator, the one we developed that showed that $20 billion would be saved annually just by applying the program to men, ages 40-59.

Accurate Detection and Prevention of Heart Disease Can Reduce Healthcare Costs, According to New Cost Analysis

A new cost analysis developed by cardiologist Dr. William Davis and his colleagues suggests that healthcare costs can be reduced by billions of dollars with the application of a simple program for heart disease detection and prevention.

Milwaukee, WI (PRWEB) July 23, 2007 -- Billions of dollars in healthcare could be saved every year by applying a simple program of heart disease detection and prevention on a wide scale in the U.S., suggests a new cost analysis developed by cardiologist Dr. William Davis and colleagues. Davis and his colleagues are the developers of the Track Your Plaque program for heart disease detection and prevention.

In the next 24 hours, 10,000 major heart procedures will be performed in hospitals across the U.S. The tab for this bill will top $400 billion in 2007 alone, nearly twice the sum spent on the war on cancer.

As costs escalate at an alarming rate, tools for prevention of disease are also advancing. While drugs like Lipitor® make headlines and dominate direct-to-consumer TV ads, a quiet revolution is taking place among physicians and the public eager to find better answers, some of which also pose opportunities for stretching the healthcare dollar.

“We’re essentially throwing away billions of dollars each and every year by ignoring the savings power of preventive strategies for heart disease,” proclaims Davis, a Milwaukee cardiologist. Davis is author of several books on heart disease detection and prevention, has been a vocal advocate for preventive strategies and is founder of www.cureality.com.

Davis and his colleagues developed a cost model to predict how much money could be saved by the adoption of new preventive strategies on a broad scale in the U.S. “The cost savings are startling. If males in the 40–59-year-old age group, for instance, were to undergo a simple CT heart scan for early detection of coronary heart disease, followed by a purposeful yet focused program of prevention using widely available tools, our cost model shows that we would save the American public over $20 billion annually. Extending this calculation to the broader population would multiply savings several-fold.”

Heart care is already the single largest healthcare category in the U.S. As costs go up by double-digit percentages, fewer people can afford healthcare. Those who can afford it spend an increasingly greater portion of their disposable income to maintain it. The Agency for Healthcare Research and Quality predicts that, at the current rate of growth, healthcare costs will balloon to absorb 20 percent of American Gross Domestic Product (GDP), about $4 trillion, in the next 10 years.

Davis points out that reducing the annual U.S. expenditure for heart disease by 20 to 30 percent could save between $80 and $120 billion each year. That marginal savings exceeds the sum the U.S. spends on the domestic war on terror.

Davis and his group have dubbed the conventional procedure-based approach to heart disease management the “crash and repair model” because of its focus on urgent procedural intervention that takes place in hospitals.

The crash and repair model is costly. According to the American Heart Association, a heart catheterization (performed 3,553 times per day, seven days a week) costs an average of $24,893; a coronary bypass operation (performed 1,170 times every day, seven days a week) costs an average of $67,823 (hospital costs, 2004, the latest year for which data are available). These figures don’t incorporate long-term costs incurred in the years following the procedure or time lost from work.

The relatively high payment to physicians and hospitals for performing high-tech heart procedures provides a disincentive to redirect patients to a less costly prevention model. The exceptional costs of high-tech, high-ticket heart procedures would become increasingly unnecessary if better heart disease preventive practices were delivered on a broad scale. “Like seatbelts, preventive measures for heart disease are more cost effective and extract a far lower toll in human suffering than the ‘crash and repair’ approach. Our cost calculations bear out the enormous savings possible. In fact, all of the tools necessary to deliver a method of early heart disease detection and prevention are already available throughout the U.S. We’ve just got to encourage physicians and the public to take advantage of them.”

The cost calculator program can be found at http://cureality.com/library/fl_hh005bankrupt.asp on the cureality.com Web site.

Track Your Plaque is an informational and educational Web site devoted to showing people how CT heart scans can be used as a starting point for a program of heart disease prevention and reversal.

What role calcium supplements?

22. July 2007 William Davis (8)

A frequent question in the Track Your Plaque program is whether taking calcium supplements to reduce risk for osteoporosis adds to calcium in arteries and raises CT heart scan scores.

No, calcium supplementation does not add to coronary calcium. Thankfully, there is some wisdom to calcium metabolism. Calcium deposition or resorption is under independent local control in bone, as it is in the artery wall. Taking calcium has no effect on calcium deposition in your coronary arteries.

However, there's a lot more to it. Taking calcium has only a modest effect on bone health. Most women can only hope to slow or stop calcium loss from bone by taking calcium supplements. Calcium supplements do not increase bone calcium. The reason why calcium supplementation works at all is, when calcium is absorbed into the blood, it provides a feedback signal to the parathyroid gland to shut down parathyroid hormone production, the hormone responsible for extracting calcium from bone. But the calcium itself does not end up deposited in bone.

Likewise, calcium supplements have essentially no effect on the artery wall. But vitamin D controls calcium absorption and, curiously, appears to exert a dramatic effect on calcium depostion in coronary arteries. In fact, I would credit vitamin D as among the most important factors in regulating arterial health that I've encountered in a long time.

Thus, bone health and arterial health do indeed intersect via calcium, but not through calcium supplements. Instead, the control exerted by vitamin D connects the seemingly unconnected processes.

Vitamin K2 provides another unexpected juxtaposition of the two processes. Deficiency of K2, which is proving to be a lot more common than previously thought, permits an enzyme in bone to exert unrestrained calcium extraction. Deficiency of K2 in artery walls allow another enzyme to deposit calcium and grow plaque without restraint. Yet another intersection between bone health and coronary health that involves calcium, but as a passive participant.

Stay tuned for a comprehensive Track Your Plaque Special Report on these topics coming in the next couple of weeks. I'm very excited about the emerging appreciation of calcium as an active ingredient in plaque, not a dumb, passive marker as previously thought. Vitamins D3 and K2 are among the keys to this phenomenon.

"Heart scans" are not always heart scans

18. July 2007 William Davis (6)

Beware of the media reports now being issued that warn that "CT heart scans" pose a risk for cancer.

One report can be viewed at
http://www.webmd.com/cancer/news/20070717/ct-heart-scan-radiation-cancer-risk.

This was triggered by a Columbia University study of risk for cancer based on the dose of radiation used in CT coronary angiograms. Theoretically, exposure to the radiation dose of CT coronary angiography can raise risk for cancer by 1 in 143 women if radiated in their 20s just from that single exposure.

If you've been following the Track Your Plaque discussion, as well as my diatribes in the Heart Scan Blog, you know that the media got it all wrong. The "heart scans" they are referring to are not the same as the heart scans that we discuss for the Track Your Plaque program.

A conventional heart scan (of the sort we refer to) exposes the recipient to 4 chest x-rays of radiation if an EBT device is used, around 8-10 chest x-rays of radiation if a 64-slice CT scanner is used. For the quality of information we obtain from these screening heart scans, we feel that it's an acceptable exposure.

The "heart scan" this study and subsequent reports refer to is not truly a screening heart scan, but a CT coronary angiogram, or CTA. CTAs are performed on the same CT or EBT devices, but involve far more radiation. CTA exposes the recipient to about 100 chest x-rays of radiation on a 64-slice device (more or less, depending on the way it is performed.) Just a couple of years ago, some centers were performing CTA on 16-slice devices, a practice I and the Track Your Plaque program vocally opposed, since up to 400 chest-rays of radiation were required! I even called a number of centers advising them that they were putting the public in jeopardy. CTAs also require injection of x-ray dye, just like any conventional angiogram.

CTA on 64-slice CT scanners require the same radiation exposure as a conventional heart catheterization, an issue glossed over in most conversations. In other words, the test that many of my colleageus so casually recommend poses a similar risk.

The message: the test I advocate for screening for coronary heart disease is a CT or EBT heart scan, not a CT coronary angiogram. CTA is a useful test and will get better and better as the engineers discover ways to reduce radiation exposure. But, in 2007, CTA is a diagnostic device, not a screening device. If you require an abdominal CT scan because your doctor suspects pancreatic cancer, or a CT scan of the brain because you might have a life-threatening aneurysm causing double-vision or seizures, it would be silly to not undergo the scan because of long-term and theoretical cancer risk.

But undergoing a CT coronary angiogram for screening purposes is ridiculous with present technology. I've said it before and I will say it--shout it--again:

CT coronary angiograms are not screening procedures; they are diagnostic procedures that should be taken seriously and do indeed pose measurable risk for cancer, a risk that is presently unacceptable for a screening test.

You wouldn't undergo a mammogram to screen for breast cancer if it exposed you to 100 chest x-rays of radiation, would you? Screening tests should be safe, reliable, accurate, and inexpensive. CT coronary angiography is none of these things. Genuine heart scans--the kind the Track Your Plaque program talks about and relies on--is all of those things.

Heavy traffic and heart scans

17. July 2007 William Davis (4)

A German study just reported in Circulation showed a graded response of EBT heart scan scores and proximity to traffic.

Living 50 meters (around 150 feet) from traffic increased the likelihood of a higher coronary calcium score by 63% compared to those living 200 meters (around 600 feet or two football fields) away from traffic.

A sample news story can be found at http://healthday.com/Article.asp?AID=606431.

The German investigators speculated that either the heightened exposure to exhaust fumes and/or the increased stress triggered by the constant noise might be the culprits behind the phenomenon.

I think the study is interesting in a number of ways from the Track Your Plaque viewpoint:

--Sometimes, there are factors that extend beyond lipoproteins, vitamin D restoration, optimism vs. pessimism, etc. that influence heart scan scoring. Are these factors powerful enough to overcome the adverse effects of traffic or other environmental effects? Can your proximity to traffic make or break your heart scan score-controlling efforts? This remains to be established.

--How much of a role does the stress issue play? Is this just a variation of the optimism vs. pessimism theme? I know when I'm in traffic in a car or on a bicycle, it often feels like I am at the mercy of hordes of people in a hurry, the soccer Moms on cell phones, applying makeup and eating, the hormonal teenager, the occasional drunk. Living in the midst of it must be demoralizing, a sense that you are lost in a sea of uncaring humanity stripped of individuality. When I look outside my den window right now, I see the lawn that I cut and water and the flowers and evergreen trees I've planted over the years. It provides a sense of life, belonging, and earth. What if instead I saw anonymous cars buzzing by, dozens of unfamiliar faces every minute, none of which plays any palpable role in my life?

--This simple observation will add to the healthy-consciousness and Green movements, since it is just one more piece of evidence that congestion and urbanization do indeed take their toll. In an obtuse way, I think this is one step closer to increasing disillusionment over the "over-processing" of human experience: processed foods, depersonalization and alienation in neighborhoods and homes, the dissolution of the American family.

Lastly, notice how the conversation about CT (in this case, EBT) heart scanning has seamlessly worked its way into conversation? Just ten years ago, a long-winded explanation would have been required in press reports on just what CT heart scanning was. Now, the information is presented and--well, we all know what heart scanning is, right?

A small study but one that comes at an important time. Good things will come from this one study. It will work its way into discussions about where to locate schools, how to situate homes in relation to heavy traffic, it will help "legitimize" this wonderful tool called heart scanning. How many medical tests beyond blood work can be easily performed in 4500 study participants?

I always like to take some simple observation and see how it fits into developing trends. Few studies or other human-generated experiences by themselves change the world. Instead, it happens in little incremental bits and pieces.

Digging for the truth

15. July 2007 William Davis (9)

I remain continually amazed how difficult it can be to gain an understanding of what is true and what is not true. I am particularly worried about the messages provided by agencies that stand to make enormous gains by persuading us to believe their version of the "truth".

For a moment, let's strip away the charitable covers of some financially-motivated organizations and see what they really look like:

Hospitals: The dream of hospitals is to shift the proportion of patients towards those with the most profitable diseases in well-insured patients. Heart disease is among the best paying diseases. HOSPITALS WANT YOU TO HAVE HEART DISEASE.

Doctors: Many (though not all) want to deal with diseases that pay well. Implanting a stent can pay several thousand dollars. Putting in a defibrillator can likewise pay handsomely, even better than stents. DOCTORS WANT TO STEER YOU TOWARDS PROCEDURES THAT REIMBURSE GENEROUSLY. Talk is cheap and pays poorly. Heart scans? Useless, since they're cheap. CT angiography? Now we're talking! $1800 dollars is a lot more interesting than $200 or so for a simple heart scan. CT angiograms also lead to catheterization, stents, hospitalizations.

Drug manufacturers: The holy grail for drug manufacturers is a chronic condition that is present in large numbers of people. An antibiotic, for instance, is a drug manufacturers waste of time: Short courses of treatment in relatively few people. Cholesterol drugs, blood pressure drugs, drugs to modify personality or some aspect of behavior--these you take for years, decades, or a lifetime, and millions are persuaded they need them. DRUG COMPANIES WANT CHRONIC CONDITIONS (WHETHER OR NOT THEY'RE DISEASES) IN PEOPLE WHO SURVIVE FOR A LONG TIME, NOT SICK PEOPLE.

Supplement manufacturers: What don't we need in the eyes of sellers of nutritional supplement? While a program like Track Your Plaque makes liberal use of supplements in a focused and, I believe, rational way, supplement sellers want you to take dozens or preparations of dubious value: milk thistle, hawthorne, ribose, hoodia, silymarin, hydroxycitric acid . . . Unlike the larger ambitions and bigger money of the pharmaceutical industry, the supplement industry is often driven by the momentary craze and the quick payoff. THE SUPPLEMENT INDUSTRY IS LOOKING FOR SUCKERS.

Food manufacturers: The holy grail for the food industry are foods that have high markups, are convenient (e.g., eaten right out of the box or package), and are purchased repeatedly. Even better, if a health claim can be added, it can ride the current wave of the public's health consciousness. Thus, Cocoa Puffs can be labeled "Heart Healthy". How about foods that have addictive potential and virtually ensure repeat sales? Eat some and you want more within 2-4 hours! As nutritionist Marion Nestle says, the mantra of the foods industry is "Eat More". It is my firm conviction that the epidemic of obesity in the U.S. is not due to laziness, video games, and computers. It is the fault of food manufacturers. FOOD MANUFACTURERS WANT US FAT AND HUNGRY AND WANT US TO STAY THAT WAY. What pays better, a 110 lb vegetarian woman who shops at the farmer's market and buys locally produced foods, or the 260 lb glutenous and always-hungry woman who fills her supermarket shopping cart with 15 cents worth of flour and sugar priced at $4.59 (cleverly disguised as a healthy breakfast cereal), instant mixes, convenient meals, energy bars, and chips?

Government agencies: User fees for the FDA paid by drug companies have caused the FDA to be beholden to drug company pressures. The USDA, charged with crafting the food pyramid, was created to support the farm industry and distributors of their products, not to disseminate public health. The food pyramid is the watered down end result of food industry lobbying and threats, not the scientific advice of nutritionists. GOVERNMENT AGENCIES SERVE INDUSTRY FIRST, THE PUBLIC SECOND.

Health websites: Read popular websites like WebMD for information and the conversation quickly steers towards drugs. "Natural treatments for cholesterol" talks about reducing saturated fat and then gushes about the wonders of statin drugs. Guess where 80% of WebMD's revenues come from? Yup, the drug industry. The same goes for many magazines, TV shows, and other media. MEDIA IS OFTEN THE TOOL OF BIG INDUSTRY.

I'm sounding like a conspiracy theorist. I don't believe that I am, but I am skeptical of the messages we often receive from the media, advertisements, news reports, websites, etc. It's left to you and me to use our judgment and decide what is truth and what is someone's version of a message crafted towards their hidden agenda.

I am hoping that the real truth will grow through a wiki-like phenomena driven and supervised by a collective knowledge that we all contribute towards. That will happen, most likely, on the internet. Just as Wikipedia overtook the revered Encylopedia Britannica in the blink of an eye at far less cost yet with greater depth and equivalent accuracy, so will it happen in health information. I'm uncertain of the eventual form this health-wiki will take, but it will shatter many smug and deeply-entrenched powers that at present continue to profit from mis-information.

A new Track Your Plaque record: 63% reduction

14. July 2007 William Davis (3)

Stress can booby-trap the best efforts at reducing your CT heart scan score.

But Amy, our newest Track Your Plaque record holder, defied the effects of an overwhelmingly life stress to drop her heart scan score from 117 to 43--an amazing 63% reduction.

Amy beat our previous record holder, Neal, who achieved a 51% reduction. Though Neal had dropped his score from 339 to 161, a drop of 178 and more than Amy's 74 point drop, on a percentage basis Amy holds the record.

I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!

Amy's complete story can be found in our latest Track Your Plaque Newsletter to be released later this week, as well as an upcoming feature on the www.cureality.com website. (We've got to toot our horn about successes like this!)

The Ornish diet made me fat

13. July 2007 William Davis (16)

I got that kind of question today that tempts me to roll my eyes and say, "Not again!"

"If I want to reverse my heart scan score, should I do the Ornish diet?" You know, the one by Dr. Dean Ornish: Dr. Dean Ornish's Program for Reversal of Heart Disease.

I personally followed the Ornish program way back in the early 1990s. I reduced fat intake of all sorts to <10% of calories; eliminated all fish and meats, vegetable oils, and nuts; ate vegetables and fruits; and upped my reliance on whole grains. I used many of his recipes. I exercised by running 5 miles per day. (Far more than I do now!) I avoided sweets like candies and fruit juices.

What happened?

I gained 31 lbs, going from 155 to 186 lbs (I'm 5 ft 8 inches tall), my abdomen developed that loose, fleshy look, hanging over my beltline. My HDL plummeted to 28 mg/dl, triglycerides skyrocketed to 336 mg/dl, and I developed a severe small LDL pattern. I experienced a mental fogginess every afternoon. I felt tired and crabby much of the time. I sometimes struggled to suppress an irrational anger and frustration over the silliest things. I required huge amounts of coffee just to function day to day.

Hundreds of my patients suffered similar phenomena.

Few of us wear bell-bottomed jeans, tie-dyed t-shirts, or say "groovy". Rowan and Martin's Laugh-in is an "oldie", it's no longer cool to hold your index and middle fingers up in the "V" sign of peace. Even Ladybird Johnson has passed.

So should go the misadventures of the ultra low-fat diet, as articulated by Dr. Ornish. His day came and went. We learned from our mistakes. Now let's do something better.

Keep your eyes open for the New Track Your Plaque Diet.

Do lower heart scan scores grow faster?

11. July 2007 William Davis (0)

If Mary's heart scan score increases from 2 to 4 in one year, it represents a 100% increase in score.

If Jane's heart scan score increases from 1002 to 1004 over the same period, it represents <1% increase, even though the true growth is the same: 2 points.

This quirk of arithmetic needs to be factored in whenever you and your doctor try to puzzle out the meaning of an increasing CT heart scan score. Lower numbers, particularly those <100, can grow at seemingly much faster rates if viewed by percent per year increase. If no effort is taken to stop the growth in your coronary plaque, then scores of 10, 20, 30, or the like can easily grow 50-100% per year.

In contrast, scores of 1000, 1500, and 2000 tend to grow at "slower" rates of 20% or so per year without corrective efforts, even though the absolute growth may be substantial. (Obviously, this bit of confusion can be best eliminated by reducing your heart scan score, but it doesn't always work out that way.)

If we were all adept at advanced math, we should probably rely on logarithmic measures of plaque increase, rather than percent increase. Or, you can just keep in mind that the rate of plaque growth must always be viewed in the context of the absolute score.

Mr. Salazar: Check your Lp(a)

9. July 2007 William Davis (8)

Marathon star Alberto Salazar was just released from the hospital following a heart attack and a heart catheterization that led to a stent. The MSNBC version of the report can be viewed at http://www.msnbc.msn.com/id/19653682/.

At 48 years old and holder of several American records for marathon times, Salazar's story is eerily reminiscent of Jim Fixx, who died at age 52 after writing a bestselling book, The Complete Book of Running. Thankfully, Salazar's story has a happier ending.

Fixx died at a time when prevention of heart disease was quite primitive. Lipoprotein analysis was not broadly available to the public, CT heart scans had not yet been invented. Even statin drugs were just a gleam in the pharmaceutical industry's eye.

But not so with Salazar. This Cuban-born marathoner experienced his heart attack at at a time when enormously useful steps can be taken to 1) document the extent of disease with a CT heart scan (the presence of a stent just means that one artery can't be "scored"), and 2) identify the causes of his disease.

I suspect that the fact that yet another marathoner in the limelight will once again prompt the (likely non-sensical) conversation about long-distance running and the increased risk of heart disease. Unfortunately, I fear that the real cause will be left unidentfied and untreated: Lipoprotein(a), or Lp(a).

It's almost certain that Fixx had Lp(a), given the fact that his dad had a heart attack at age 35. Running simply postponed the untreated inevitable.

I hope Mr. Salazar is surrounded by doctors who have his true interests in mind (not just procedural excitement) and ask the crucial question: Why?

The answer is almost certain to be Lp(a).

Cureality | Real People Seeking Real Cures

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.

Amber’s Top 35 Health and Fitness Tips

7. November 2014 Amber B (0)

This year I joined the 35 club! And in honor of being fabulous and 35, I want to share 35 health and fitness tips with you!

1. Foam rolling is for everyone and should be done daily.
2. Cold showers are the best way to wake up and burn more body fat.
3. Stop locking your knees. This will lead to lower back pain.
4. Avoid eating gluten at all costs.
5. Breath deep so that you can feel the sides or your lower back expand.
6. Swing a kettlebell for a stronger and great looking backside.
7. Fat is where it’s at! Enjoy butter, ghee, coconut oil, palm oil, duck fat and many other fabulous saturated fats.
8. Don’t let your grip strength fade with age. Farmer carries, kettlebells and hanging from a bar will help with that.
9. Runners, keep your long runs slow and easy and keep your interval runs hard. Don’t fall in the chronic cardio range.
10. Drink high quality spring or reverse osmosis water.
11. Use high quality sea salt season food and as a mineral supplement.
12. Work your squat so that your butt can get down to the ground. Can you sit in this position? How long?
13. Lift heavy weights! We were made for manual work,. Simulate heavy labor in the weight room.
14. Meditate daily. If you don’t go within, you will go with out. We need quiet restorative time to balance the stress in our life.
15. Stand up and move for 10 minutes for every hour your sit at your computer.
16. Eat a variety of whole, real foods.
17. Sleep 7 to 9 hours every night.
18. Pull ups are my favorite exercise. Get a home pull up bar to practice.
19. Get out and spend a few minutes in nature. Appreciate the world around you while taking in fresh air and natural beauty.
20. We all need to pull more in our workouts. Add more pulling movements horizontally and vertically.
21. Surround yourself with health minded people.
22. Keep your room dark for deep sound sleep. A sleep mask is great for that!
23. Use chemical free cosmetics. Your skin is the largest organ of your body and all chemicals will absorb into your blood stream.
24. Unilateral movements will help improve symmetrical strength.
25. Become more playful. We take life too seriously, becoming stress and overwhelmed. How can you play, smile and laugh more often?
26. Choose foods that have one ingredient. Keep your diet simple and clean.
27. Keep your joints mobile as you age. Do exercises that take joints through a full range of motion.
28. Go to sleep no later than 10:30pm. This allows your body and brain to repair through the night.
29. Take care of your health and needs before others. This allows you to be the best spouse, parent, coworker, and person on the planet.
30. Always start your daily with a high fat, high protein meal. This will encourage less sugar cravings later in the day.
31. Approach the day with positive thinking! Stinkin’ thinkin’ only leads to more stress and frustration.
32. You are never “too old” to do something. Stay young at heart and keep fitness a priority as the years go by.
33. Dream big and go for it.
34. Lift weights 2 to 4 times every week. Strong is the new sexy.
35. Love. Love yourself unconditionally. Love your life and live it to the fullest. Love others compassionately.

To Change, You Need to Get Uncomfortable

25. September 2014 Amber B (0)

Sitting on the couch is comfortable. Going through the drive thru to pick up dinner is comfortable. But when you notice that you’re out-of-shape, tired, sick and your clothes no longer fit, you realize that what makes you comfortable is not in align with what would make you happy.

You want to see something different when you look in the mirror. You want to fit into a certain size of jeans or just experience your day with more energy and excitement. The current condition of your life causes you pain, be it physical, mental or emotional. To escape the pain you are feeling, you know that you need to make changes to your habits that keep you stuck in your current state. But why is it so hard to make the changes you know that will help you achieve what you want?

I want to lose weight but….

I want a six pack but…

I want more energy but….

The statement that follows the “but” is often a situation or habit you are comfortable with. You want to lose weight but don’t have time to cook healthy meals. So it’s much more comfortable to go through the drive thru instead of trying some new recipes. New habits often require a learning curve and a bit of extra time in the beginning. It also takes courage and energy to establish new routines or seek out help.

Setting out to achieve your goals requires change. Making changes to establish new habits that support your goals and dreams can be uncomfortable. Life, as you know it, will be different. Knowing that fact can be scary, but so can staying in your current condition. So I’m asking you to take a risk and get uncomfortable so that you can achieve your goals.

Realize that it takes 21 days to develop a new habit. I believe it takes triple that amount of time to really make a new habit stick for the long haul. So for 21 days, you’ll experience some discomfort while you make changes to your old routine and habits. Depending on what you are changing, discomfort could mean feeling tired, moody, or even withdrawal symptoms. However, the longer you stick to your new habits the less uncomfortable you start to feel. The first week is always the worst, but then it gets easier.

Making it through the uncomfortable times requires staying focused on your goals and not caving to your immediate feelings or desires. I encourage clients to focus on why their goals important to them. This reason or burning desire to change will help when old habits, cravings, or situations call you back to your old ways.
Use a tracking and a reward system to stay on track. Grab a calendar, journal or index card to check off or note your daily successes. Shoot for consistency and not perfection when trying to make changes. I encourage my clients to use the 90/10 principle of change and apply that to their goal tracking system. New clothes, a massage, or a day me-retreat are just a few examples of rewards you can use to sticking to your tracking system. Pick something that really gets you excited.

Getting support system in place can help you feel more comfortable with being uncomfortable. Hiring a coach, joining an online support group, or recruiting family and friends can be very helpful when making big changes. With a support system in place you are not alone in your discomfort. You’re network is there for you to reach out for help, knowledge, accountability or camaraderie when you feel frustrated and isolated.

I’ve helped hundreds of people change their bodies, health and lives of the eleven years I’ve worked as a trainer and coach. I know it’s hard, but I also know that if they can do it, so can you. You just need to step outside of your comfort zone and take a risk. Don’t let fear create uncomfortable feelings that keep you stuck in your old ways. Take that first step and enjoy the journey of reaching your goals and dreams.

The 3 Best Grain Free Food Swaps to Boost Fat Burning

25. September 2014 Lisa G (0)

You can join others enjoying substantial improvements in their health, energy and pant size by making a few key, delicious substitutions to your eating habits. This is possible with the Cureality nutrition approach, which rejects the idea that grains should form the cornerstone of the human diet.

Grain products, which are seeds of grasses, are incompatible with human digestion. Contrary to what we have been told for years, eating healthy whole grain is not the answer to whittle away our waists. Consumption of all grain-based carbohydrates results in increased production of the fat storage hormone insulin. Increased insulin levels create the perfect recipe for weight gain. By swapping out high carbohydrate grain foods that cause spikes in insulin with much lower carbohydrate foods, insulin release is subdued and allows the body to release fat.

1. Swap wheat-based flour with almond flour/meal

One of the most dubious grain offenders is modern wheat. Replace wheat flour with naturally wheat-free, lower carbohydrate almond flour.
Almond flour contains a mere 12 net carbs per cup (carbohydrate minus the fiber) with 50% more filling protein than all-purpose flour.
Almond flour and almond meal also offer vitamin E, an important antioxidant to support immune function.

2. Swap potatoes and rice for cauliflower

Replace high carb potatoes and pasta with vitamin C packed cauliflower, which has an inconsequential 3 carbs per cup.
Try this food swap: blend raw cauliflower in food processor to make “rice”. (A hand held grater can also be used). Sautee the “riced” cauliflower in olive or coconut oil for 5 minutes with seasoning to taste.
Another food swap: enjoy mashed cauliflower in place of potatoes. Cook cauliflower. Place in food processor with ½ a stick organic, grass-fed butter, ½ a package full-fat cream cheese and blend until smooth. Add optional minced garlic, chives or other herbs such as rosemary.

3. Swap pasta for shirataki noodles and zucchini

Swap out carb-rich white pasta containing 43 carbs per cup with Shirataki noodles that contain a few carbs per package. Shirataki noodles are made from konjac or yam root and are found in refrigerated section of supermarkets.
Another swap: zucchini contains about 4 carbs per cup. Make your own grain free, low-carb noodles from zucchini using a julienne peeler, mandolin or one of the various noodle tools on the market.

Not so fast. Don’t make this mistake when going gluten free!

25. September 2014 Lisa G (0)

Beginning last month, the Food and Drug Administration began implementing its definition of “gluten-free” on packaged food labels. The FDA determined that packaged food labeled gluten free (or similar claims such as "free of gluten") cannot contain more than 20 parts per million of gluten.

It has been years in the making for the FDA to define what “gluten free” means and hold food manufactures accountable, with respect to food labeling. However, the story does not end there.

Yes, finding gluten-free food, that is now properly labeled, has become easier. So much so the market for gluten-free foods tops $6 billion last year. However, finding truly healthy, commercially prepared, grain-free foods is still challenging.

A very common mistake made when jumping into the gluten-free lifestyle is piling everything labeled gluten-free in the shopping cart. We don’t want to replace a problem: wheat, with another problem: gluten free products.

Typically gluten free products are made with rice flour (and brown rice flour), tapioca starch, cornstarch, and potato flour. Of the few foods that raise blood sugar higher than wheat, these dried, powdered starches top the list.

They provide a large surface area for digestion, thereby leading to sky-high blood sugar and all the consequences such as diabetes, hypertension, cataracts, arthritis, and heart disease. These products should be consumed very rarely consumed, if at all. As Dr. Davis has stated, “100% gluten-free usually means 100% awful!”

There is an ugly side to the gluten-free boom taking place. The Cureality approach to wellness recommends selecting gluten-free products wisely. Do not making this misguided mistake and instead aim for elimination of ALL grains, as all seeds of grasses are related to wheat and therefore overlap in many effects.

3 Foods to Add to Your Next Grocery List

25. September 2014 Lisa G (0)

Looking for some new foods to add to your diet? Look no further. Reach for these three mealtime superstars to encourage a leaner, healthier body.

Microgreens

Microgreens are simply the shoots of salad greens and herbs that are harvested just after the first leaves have developed, or in about 2 weeks. Microgreen are not sprouts. Sprouts are germinated, in other words, sprouted seeds produced entirely in water. Microgreens are grown in soil, thereby absorbing the nutrients from the soil.

The nutritional profile of each microgreen depends greatly on the type of microgreen you are eating. Researchers found red cabbage microgreens had 40 times more vitamin E and six times more vitamin C than mature red cabbage. Cilantro microgreens had three times more beta-carotene than mature cilantro.

A few popular varieties of microgreens are arugula, kale, radish, pea, and watercress. Flavor can vary from mild to a more intense or spicy mix depending on the microgreens. They can be added to salads, soup, omelets, stir fry and in place of lettuce.

Cacao Powder

Cocoa and cacao are close enough in flavor not to make any difference. However, raw cacao powder has 3.6 times the antioxidant activity of roasted cocoa powder. In short, raw cacao powder is definitely the healthiest, most beneficial of the powders, followed by 100% unsweetened cocoa.

Cacao has more antioxidant flavonoids than blueberries, red wine and black and green teas. Cacao is one of the highest sources of magnesium, a great source of iron and vitamin C, as well as a good source of fiber for healthy bowel function.
Add cacao powder to milk for chocolate milk or real hot chocolate. Consider adding to coffee for a little mocha magic or sprinkle on berries and yogurt.

Shallots

Shallots have a better nutrition profile than onions. On a weight per weight basis, they have more anti-oxidants, minerals, and vitamins than onions. Shallots have a milder, less pungent taste than onions, so people who do not care for onions may enjoy shallots.

Like onions, sulfur compounds in shallot are necessary for liver detoxification pathways. The sulfur compound, allicin has been shown to be beneficial in reducing cholesterol. Allicin is also noted to have anti-bacterial, anti-viral, and anti-fungal activities.

Diced then up and add to salads, on top of a bun less hamburger, soups, stews, or sauces. Toss in an omelet or sauté to enhance a piece of chicken or steak, really the possibilities are endless.

3 Band Exercises for Great Glutes

15. August 2014 Amber B (0)

Bands and buns are a great combination. (When I talk about glutes or a butt, I use the word buns) When it comes to sculpting better buns, grab a band. Bands are great for home workouts, at gym or when you travel. Check out these 3 amazing exercises that will have your buns burning.

Band Step Out

Grab a band and place it under the arch of each foot. Then cross the band and rest your hands in your hip sockets. The exercise starts with your feet hip width apart and weight in the heels. Slightly bend the knees and step your right foot out to the side. Step back in so that your foot is back in the starting position. With each step, make sure your toes point straight ahead. The tighter you pull the band, the more resistance you will have. You will feel this exercise on the outside of your hips.

Start with one set of 15 repetitions with each foot. Work on increasing to 25 repetitions on each side and doing two to three sets.

Band Kick Back

This exercise is performed in the quadruped position with your knees under hips and hands under your shoulders. Take the loop end of the band and put it around your right foot and place the two handles or ends of the band under your hands. Without moving your body, kick your right leg straight back. Return to the starting quadruped position. Adjust the tension of the band to increase or decrease the difficulty of this exercise.

Start with one set of 10 repetitions with each foot. Work on increasing to 20 repetitions on each side and doing two to three sets.

Band Resisted Hip Bridge

Start lying on your back with feet hip distance apart and knees bent at about a 45-degree angle. Adjust your hips to a neutral position to alleviate any arching in your lower back. Place the band across your hipbones. Hold the band down with hands along the sides of your body. Contract your abs and squeeze your glutes to lift your hips up off the ground. Stop when your thighs, hips and stomach are in a straight line. Lower you hips back down to the ground.

Start with one set of 15 repetitions. Work on increasing to 25 repetitions and doing two to three. Another variation of this exercise is to hold the hip bridge position. Start with a 30 second hold and work up to holding for 60 seconds.

American Heart Association stamp of approval

2. June 2007 William Davis (8)

The American Heart Association (AHA) has a program called the Heart-Check Mark, an "approval" process that permits a food manufacturer to affix the AHA logo and stamp of approval on various food products.

A company simply makes application to the AHA. The application and product details are reviewed and then approved or turned down.

To date, 106 companies have obtained the AHA stamp of approval on 768 products. What kinds of products are on the approved list? Here's a sample:

--Honey Bunches of Oats

--Kellogg's Frosted Mini-Wheats

--Cocoa Puffs cereal

--Cookie Crisp cereal ("The great taste of chocolate chips in every bite!")

There are 764 others. If you doubt this, just go to the store and take a look at the product containers.

What the heck is going on here? Most of us with any judgment know that these products are pure sugar. They may contain "no more" than 15-40 grams sugar per sugar, but the principal products--corn, wheat, fructose--mean that these products are, in effect, nearly pure sugar. Yet they carry the AHA stamp of approval.

What do products like this cause? It's a long list but the major effects include:

--Obesity

--Diabetes

--Drop in HDL

--Rise in triglycerides

--Small LDL particles

--Heightened inflammation (i.e., C-reactive protein)

--Mental cloudiness

Need I go on? Why are products like these and many others deserving of the AHA heart-check approval? Because they lack high fat and saturated fat (3.0 grams, 1.0 grams respectively, by AHA criteria). In other words, just lacking these ingredients means that, to the AHA, they qualify as "heart healthy."

By that same line of reasoning, many candy bars are "heart healthy", as are many cookies and cupcakes.

What's the reason behind this extraordinary absurdity? Is the AHA stupid?

There may be many reasons, but one very suspicious fact becomes immediately obvious when you realize these endorsements product a substantial revenue source for the AHA, since companies must pay for the right to use the heart-check approval mark. Also, just look at the major contributors (millions of dollars) to the AHA: ConAgra, General Mills, Kraft, etc.) You get the picture.

Does this make the AHA evil? Not necessarily. But it seriously erodes credibility. it also should make you very leery of any advice that comes from such an agency that is reluctant to bite the food manufacturer hands that feed it.

In my view, we simply cannot rely on the AHA for genuine, unbiased heart health advice.

"Your heart scan score means nothing"

1. June 2007 William Davis (7)

Charles was visibly confused.

He'd gotten his CT heart scan after hearing one of the local scan center's ads on the radio. His score 2773, obviously in the 99th percentile for any age.

"Do you think the score means anything? My primary doctor said that it was meaningless because it was all in the deep wall of the artery. He said that it has nothing to do with risk for heart attack. As long as I feel good, he says don't do anything."

What exactly did his doctor mean, in the "deep wall of the artery"?

What the doctor is referring to is the fact that some people with a long history (many years) of diabetes or kidney failure (also for many years) tend to develop calcium deposits in the media, or muscular layer of arteries. The media is the tissue thin layer just below the intima, the most inner layer of arteries that we usually associate with atherosclerotic plaque and the layer that is most prone to calcium accumulation that we score on heart scans.

Aging, generally into your late 70s, 80s, and onwards, also increases the likelihood of medial calcification. Lastly, longstanding deficiency of vitamin D encourages medial calcification.

Is there any way to distinguish intimal vs medial calcification on a heart scan? No, there is not. Having read many thousands of CT heart scans, I can tell you that there is no practical way in 2007 to tell the difference.

Then how did this doctor "know" that Charles' calcium was "deep walled" or medial? Simple: He didn't. This was yet another example of ignorance based on old thinking. Unfortunately, he did Charles a serious disservice by dismissing his heart scan score that predicted a 25% per year risk for heart attack.

Interestingly, whether calcium is intimal as in atherosclerotic plaque, or medial, both are strongly associated with risk for heart attack. In other words, if calcium is confined to the intima, heart disease risk is present. If calcium is limited to the media, risk is still present.

In all practicality, the only difference we make of the intima vs. media argument (that is, when the distinction has been made by some other means like intracoronary ultrasound, the test that is truly necessary to distinguish the two patterns) is that medial calcification may be more powerfully related to vitamin D deficiency. Thus, someone with heavy medial calcification may require closer attention to maintaining a perfect year-round blood level of 25-OH-vitamin D3. But that's the only practical difference.

Vitamin D toxicity?

30. May 2007 William Davis (3)

"My primary care doctor said to stop the vitamin D because it's toxic. So I stopped it and I just take a multivitamin. He said that a multivitamin and two glasses of milk a day was all I needed."

So proclaimed Eleanor to me. This happens around once every week by doctors frightened of the vitamin D.

So I reminded Eleanor that, before starting vitamin D supplementation, her blood level of 25-OH-vitamin D3 had been 17 ng/ml--severe deficiency.

On 4000 units per day (oil-based gelcap), her blood level had been 37 ng/ml--still deficient, below the desirable range of 50-60 ng/ml. That's the dose Eleanor's doctor had declared "toxic."

When exactly does deficiency develop? There's not full agreement on this, but Dr. Michael Holick of Boston University, among the most experienced and insightful authorities on vitamin D, states that toxicity is more likely when blood levels exceed 150 ng/ml (Nutr Clin Pract. 2007 Jun;22(3):297-304).

In other words, Eleanor and her doctor should not be concerned with toxicity, but with the persistent levels of deficiency she is suffering.

Some authorities call the behavior of vitamin D "bi-phasic": Deficiency is toxic, excessive levels are toxic. We're really just trying to achieve a middle ground in vitamin D levels that are above deficiency but below toxicity.

In reality, deficiency is exceptionally common. In fact, it's the rule around here (northern U.S.), with >95% of everybody we check severely deficient in winter, mildly-moderately deficient in summer. Very few people approach normal levels year round without supplementation.

Toxicity, on the other hand, is exceedingly rare. I have seen it once in a woman who was taking a toxic dose of 50,000 units a day on the instructions of her (mis-guided) doctor. Thankfully, no ill-effects developed from this little "experiment."

So, it's not toxicity that is the overwhelmingly common worry, but deficiency, severe and sustained.

Non-profit hospitals

30. May 2007 William Davis (0)

Take a look at your local hospital and you're likely to notice several curious things:

1) It is likely non-profit, meaning it enjoys a non-profit status with the Internal Revenue Service and enjoys the tax benefits of not paying taxes on profits. This provides an advantage to tax-protected hospitals. 70% or more of hospitals in the U.S. are "non-profit."

2) Non-profit or no, many hospitals operate under the guise of a religious affiliation, e.g., St. Mary's Hospital, Trinity Hospital, All Saints', Jewish Hospital, etc.

3) Executives in non-profit hospitals can make capitalistic salaries. One CEO of a Milwaukee hospital took home $3.7 million dollars in salary last year. That's not including the very substantial perks and business interests in the spin-off businesses the hospital owns, including pharmacies, drug and medical device disitributors, even a venture capital division. "Non-profit" does not have to mean that executives within the operation can't benefit handsomely.

That same hospital system spends over $10 million dollars in a year in local marketing for TV ads, print advertising, etc. Ads are slick and professionally produced.

Make no bones about it: These are "non-profit" for tax purposes only . They are for-profit in every other sense of the phrase, including rich rewards for the insiders.

Guess how those fat executive salaries and large marketing budgets are paid for? That's right: the 12-inch incision in your chest; the four stents, defibrillator, and repeated nuclear stress tests; the revolving door of hospitalization after hospitalization that typifies the "heart patient" experience.

See the hospital for what it is: In the 21st century, it is no longer a charitable operation worthy of your volunteer time and donations. It is a business no different than Home Depot, IBM, or--Enron. Yes, they do perform needed services, as well. But the perverse equation that often determines who needs hospitalization and who doesn't, who needs a heart procedure and who doesn't, is not always based on necessity but on financial return. Just ask the CEO.

What's the best lipoprotein test?

29. May 2007 William Davis (5)

This is a frequent question from Track Your Plaque Members and others interested in improving their heart disease prevention program beyond that of simple-minded cholesterol testing.

I obtain lipoprotein testing every day on patients. I can tell you with the confidence of having done thousands of these tests that plain, old-fashioned cholesterol testing is like relying on riding a scooter to work compared to an 8-cylinder modern automobile. The scooter might get you there, but any rain, snow, or long distance to travel and you can just forget it.

All too often, lipoprotein testing uncovers abnormalities that standard cholesterol testing simply fails to uncover.

So, among the various lipoprotein tests available, which is best?

There are three commercial tests available today:

1) Gel electropheresis (GGE)--often known by its "brand" name as the Berkeley lipoprotein profile, after Berkeley HeartLabs. GGE uses a gel with an electric field applied to cause lipoproteins to migrate, based on particle size and charge.

2) Vertical auto-profile (VAP)--a form of centrifugation, or high-speed spinning of blood plasma to separate lipoprotein particles.

3) Nuclear magnetic resonance (NMR)--the idea of putting plasma in an NMR (also known as MRI) device to characterize blood proteins.

All three tests do an excellent job. All are competitively priced. All have validating data--lots of it--to justify their broad use (though health insurers, in their vast wisdom, would still have you believe that the tests are "experimental").

But is one better?

Having done many of all three (though least of VAP), I am partial to Liposcience's NMR. (By the way, I receive no fees from Liposcience to use their test, nor to promote it in any way.)

I believe NMR is superior in a few ways:

1) I believe that the LDL particle number is the best way to truly quantify LDL, better than apoprotein B and "direct" LDL.

2) It provides what I believe to be more accurate small LDL measures.

3) It provides intermediate-density lipoprotein (IDL), a post-prandial, or after-eating, measure not available on the other two.

Perhaps I'm biased because I use the NMR most frequently. But I've used it because I felt it yielded superior, more clinically believable, data.

In truth, all three laboratories do an excellent job and you'd be served fine by obtaining any of the three. But my heart goes to NMR.

Vitamin K2, aspirin, fish oil and blood thinning

27. May 2007 William Davis (12)

An interesting question came up from one of our Track Your Plaque Members on the Forum.

"I am now taking 9 mg of vitamin K1 and 1000 mcg of K2.

Does taking this supplement with this much K1 have a counteracting effect on the thinning/anticlotting properties of aspirin and fish oil that I also take?"

Great question (along with lots of other greater discussions we have on the Forum.)

The answer: Vitamin K should have no effect on the platelet-blocking effects of aspirin or fish oil. The majority of blood clot inhibiting effects of aspirin and fish oil arise from their ability to keep blood platelets from "clumping" (just like the TV commercials for Plavix).

Vitamin K, on the other hand, participates in the liver production of blood clotting factors (like II, VII, IX, and X, among others for you curious ones).

Thus, vitamin K-dependent clotting factors and platelet-blocking are two separate pathways to forming blood clots. Some of us refer to the difference as "red clots" from the vitamin K pathway and "white clots" from the platelet pathway, since they really do have this different physical appearance.

The vitamin K2 conversation, like that about vitamin D, is fascinating for its potential to provide the missing link between the tightly-tied fortunes of bone health and atherosclerosis. Why is someone with a high CT heart scan score far more likely to have osteoporosis? Vitamin D and K2 deficiency may provide the missing link for many people.

"Drug no cure for gluttony"

24. May 2007 William Davis (0)

That's the headline I'd like to see associated with rosiglitazone, brand name Avandia.

The recent negative press, whether deserved or not, surrounding the prescription drug rosiglitazone for pre-diabetes and diabetes highlights the fact that drugs never--never--substitute for what we can achieve with lifestyle changes.

Typically, rosiglitazone reduces blood sugar a few milligrams, reduces C-reactive protein, and very modestly reduces triglycerides and its associated evil lipoprotein friends. It also causes an average weight gain of 8 lb in the first year of use.

What will weight loss achieve, especially if accomplished through dramatic reduction or elimination of processed carbohydrates and wheat products, along with fish oil supplementation, vitamin D normalization, and exercise? Extraordinary benefits, far superior to what is achievable with this drug. In fact, while rosiglitazone is a Band-Aid for this process, the lifestyle changes can represent a cure in many or most instances.

It should come as no surprise that a drug that does nothing more than increase sensitivity to insulin cannot erase the devastating effects of an unhealthy life. Take rosiglitazone but neglect exercise, don't bother with vitamin D, indulge in pretzels and breakfast cereals, gain more weight . . . It serves the drug company's agenda better than it serves health.

Rosiglitazone not so rosy?

23. May 2007 William Davis (3)

Dr. Steve Nissen of the Cleveland Clinic published a study that suggests that the pre-diabetes and diabetes drug, rosiglitazone, may increase likelihood of heart attack by 43%.

I say "suggests" because the analysis was something called a "meta-analysis", a re-examination of data obtained by pooling unrelated studies and reanalyzing the data. Strengths of this sort of analysis: Sometimes trends that are not evident in smaller studies finally become evident in the larger numbers of participants obtained through pooling of data. Downside: Any statistician will tell you that a meta-analysis can only suggest an association, it cannot prove it.

Nonetheless, we are talking about people's lives. As they say, if you are taking this drug, also known by the brand name, Avandia, then talk to your doctor. I think that this is sound advice, as there are a number of factors to weigh in decision making. For instance, how far along the diabetic path are you? Have you had negative experiences with other agents?

It will, unfortunately, be months to years before confirmatory evidence on this question become available. In the meantime, Nissen will accuse the drug industry of pushing drugs through the FDA approval process without full safety data. GlaxoSmithKline, the manufacturer of Avandia, will counter with claims of weak data, the existing trials not confirming Nissen's findings, etc. We've seen it before.

My take on this is to step back and look at the broad picture. Do we need yet another reason to say that it's far better to maintain normal body weight, dramatically reduce reliance on processed carbohydrates and wheat, exercise, and following other insulin-sensitizing strategies, rather than rely on insulin-sensitizing drugs? (That's what rosiglitazone is supposed to do.) Metabolic syndrome, also known as pre-diabetes, or diabetes is present to various degrees in two thirds of all adults I meet. Nearly all of it is self-inflicted. Nearly all of it is curable with the above lifestyle strategies if undertaken early enough in the process.

A 190 lb, 5 foot 2 inch woman, or a 220 lb, 5 foot 10 inch man, both of whom are surprised that they have pre-diabetes really need to get a grip on reality and health. To me, it's no surprise that drugs do not reverse all the nasty manifestations of lifestyle gone berserk. It should also come as no surprise that the complex, chaotic physiologic mess created by metabolic syndrome and pre-diabetes is not perfectly managed by adding one drug.

The lipid distorting effects of weight loss

22. May 2007 William Davis (0)

Roger experienced a near-fatal heart attack 6 years ago. He survived thanks to the quick action of bystanders who initiated CPR and called 911. An emergency catheterization was performed and a stent implanted into the closed right coronary artery. But that's not why I tell Roger's story.

Since then, Roger has become comfortable with the idea that he has heart disease. His initial commitment to good nutrition and exercise has waned, as it often does in us distractable humans. So Roger gained about 30 lbs through a long winter, inactivity, eating frozen dinners, and the cookies and baked goodies his daughters made him.

As a result of the weight gain and inactivity, Roger's HDL dropped to 32 mg/dl, triglycerides rose to 211 mg/dl, blood sugar crept up into the pre-diabetic range of 116 mg/dl. Undoubtedly, small LDL was out of control beneath the surface. His tummy reflected the weight gain, flaccid and overhanging his belt.

I read Roger the riot act. I reminded him of what he had experienced and nearly didn't survive. Weight loss and a re-invigoration of his nutrition and exercise efforts was going to be crucial.

Roger listened and took it to heart. Over three months, he lost 24 lbs, a phenomenal result. However, his repeat lipid panel showed an HDL of 28 mg/dl, triglycerides 234 mg/dl, blood sugar unchanged.

"I don't get it! I lose all this weight and the number get worse?!" Roger was understandably upset after his enormous effort.

I told Roger that after a profound weight loss, lipids can go berserk for up to two months after weight has stabilized. Typically, HDL drops and triglycerides rise--the opposite of what we want. But wait another two or so months after weight has stabilized and the numbers begin to look beautiful.

Why does this crazy effect happen? I really don't know and I've never heard a satisfactory explanation for it. But it is very real and quite predictable.

The lesson: after a substantial weight loss, be patient. Check your lipid numbers too soon and you might be confused or disappointed. If you do check them, bear in mind that additional time may need to pass before you see the weight loss fully reflected.

Cholesterol reduction and wheat

22. May 2007 William Davis (0)

In my previous post, Identical twins and the explosive influence of weight , we witnessed an excellent example of the profound influence of food choices and weight control on lipoproteins. The heavier twin among these 35-year old male twins (Steve) had an LDL particle number over two-fold higher than his more slender counterpart (Alfred).

The heavier twin, Steve, got here through numerous and longstanding dietary excesses: fast foods, saturated fats, sweets, processed foods. The conventional answer to Steve's lipid dilemma would be to modestly reduce his reliance on saturated fat, exercise, and limit snacks.

How far would that get Steve? Not very far at all. With regards to his high LDL particle number of 2256 nmol/l (representing an "effective" LDL cholesterol of around 225 mg/dl), it would be reduced a little, perhaps 10%.

Notice, however, that 72% of all Steve's LDL particles are small (1639/2256). This is the pattern that responds dramatically to a sharp reduction in processed carbohydrates, especially wheat-containing products.

If Steve were to eliminate all wheat products--all breads, breakfast cereals, pretzels, cookies, cakes, pasta, crackers--LDL particle number will drop dramatically, perhaps 50%, often more depending on the magnitude of weight loss. Small LDL will respond most obviously and will be sharply reduced, perhaps disappear. Incidentally, these changes might not be well reflected by the conventional calculated LDL cholesterol, since small LDL particles are well-concealed by standard measures.

Reducing corn products, white and brown rice, and potatoes would also add to the effect. But, in 2007, wheat products represent 90% of the problem for the majority of people. Reducing or eliminating wheat therefore yields the biggest effect by a long shot.

Steve therefore represents an excellent example of how reducing processed carbohydrates, esp. wheat-containing products, can yield an unexpected and paradoxical reduction in LDL cholesterol as evidenced by the highly accurate LDL particle number (or apoprotein B). Reducing saturated fat sources also helps, but it certainly will not yield the kind of results most people need. You've got to be smarter than the simple-minded conventional advice.
