Add Boston Globe to the list of heart scan blunders

17. September 2008 William Davis (15)

Yet another piece of mass media misinformation hit the airwaves today. This time it's not from the New York Times or the LA Times, both of which have previously mangled the issues surrounding heart scans. This time it's from the Boston Globe.

In an article titled What is a calcium scan for heart disease, and who should undergo the test?, the report states:

". . . calcium scans may not be a good idea, or prove terribly useful, for most people. For one thing, the scans expose a patient to significant radiation - equivalent to roughly 50 chest X-rays" said Dr. Warren Manning, chief of noninvasive cardiac imaging at Beth Israel Deaconess Medical Center."

As many before him, Dr. Manning is confusing two tests: CT coronary angiography and CT heart scanning. Perhaps we can't blame him: This technology has had its weakest following in the northeast, for reasons not entirely clear to me. (In fact, Track Your Plaque followers have had the greatest struggle obtaining heart scans in that part of the country.) Nonetheless, you'd think he'd have his simple facts straight before talking to the press. Unfortunately, hospital public relations departments will usually just grab whoever they can willing to talk to the press--regardless of their expertise or lack of.

The story goes on to say:

. . ." it's not clear what to do with the results from a calcium scan. If you have diabetes, high cholesterol, high blood pressure, or a family history of heart disease, you already know - or should know - that you are at increased risk of heart problems and should lower these risk factors. So, a calcium scan provides little additional information," Manning said.

"Moreover, even a high score doesn't necessarily mean that the calcified plaque in your arteries is obstructing blood flow, said Dr. Adolph Hutter, a cardiologist at Massachusetts General Hospital."

"The vast majority of people with high calcium tests don't have obstructions and they do fine long-term. So you'd have to test lots and lots of people to prevent one heart attack or sudden death," said Manning.

And if you get a low calcium score, a sign of little or no calcification of plaques, that's not very useful, either, because it could be wrong, or it could be right but lull you into believing you do not have to exercise and watch your diet, cholesterol, and blood pressure levels. "You can still be at risk even if your calcium test is negative," Hutter said.

It is truly shocking how little many (not all, thank goodness) of my colleagues really know about 1) heart scans, 2) coronary disease prevention, and 3) prevention in general. These same "experts" likely advocate high-dose statin drugs and low-fat diets for people at risk. They likely refer patients to the American Heart Association for diet advice and themselves obtain a lot of information from the pharmaceutical industry. The notion of identification, tracking, and purposeful reversal of coronary plaque is entirely foreign to this bunch.

"The vast majority of people with high calcium tests don't have obstructions and they do fine long-term. So you'd have to test lots and lots of people to prevent one heart attack or sudden death." Well, take a look at a graph from a database of 25,000 people undergoing heart scans then observed for several years afterwards:

You can see quite clearly from the curves that heart scan scores very clearly predict your future (if no preventive action is taken). The higher the score, the greater the likelihood of heart attack and death. How much clearer can it get?

The most recent addition to this literature is the PREDICT study which concluded:

Hazard ratios relative to CACS [coronary artery calcium scores] in the range 0-10 Agatston units (AU) were: CACS 11-100 AU, 5.4 (P = 0.02); 101-400 AU 10.5 (P = 0.001); 401-1000 AU, 11.9 (P = 0.001), and >1000 AU, 19.8 (P < 0.001).

In other words, a heart scan score of >1000 is associated with a 20-fold increased risk of cardiovascular events (without preventive efforts). That kind of predictive power and quantitative confidence simply cannot be squeezed out of blood pressure and cholesterol values.

How about the 2008 University of California-Irvine study from the New England Journal of Medicine (do the northeast docs even pay attention to something that is published in their own neighborhood?) that reported:

There were 162 coronary events, of which 89 were major events (myocardial infarction or death from coronary heart disease). In comparison with participants with no coronary calcium, the adjusted risk of a coronary event was increased by a factor of 7.73 among participants with coronary calcium scores between 101 and 300 and by a factor of 9.67 among participants with scores above 300 (P<0.001 for both comparisons). Among the four racial and ethnic groups, a doubling of the calcium score increased the risk of a major coronary event by 15 to 35% and the risk of any coronary event by 18 to 39%.

How about the Prospective Army Coronary Calcium (PACC) project (men average age 43 years):

"In these men, coronary calcium was associated with an 11.8-fold increased risk for incident coronary heart disease (CHD) (p = 0.002) in a Cox model controlling for the Framingham risk score. Among those with coronary artery calcification, the risk of coronary events increased incrementally across tertiles of coronary calcium severity (hazard ratio 4.3 per tertile)."

Calcium score provided additional information even after factoring in the Framingham risk score.

That's just a sample of the studies. There are a number more.

Add to these conversations the fact that, unlike reducing blood pressure or LDL cholesterol, the heart scan score is a quantification of the disease itself. It can also be tracked over time to gauge the success or failure of prevention efforts. To believe that blood pressure reduction or LDL cholesterol reduction is sufficient to eliminate risk is something only a fool would believe.

Contary to the above statements, the data are clear:

--The higher the heart scan score, the greater the risk. This has been demonstrated beyond any shadow of a doubt in at least a dozen published studies. In fact, heart scan scores outshine lipid/cholesterol values several-fold.

--A person with a zero score has a nearly zero risk for cardiovascular events over a 5-year timeline.

--Heart scans are the only quantitative test available of coronary atherosclerotic plaque. This means that they can be repeated to gauge progression or regression. Cholesterol does not do that. Stress tests do not do that.

--Heart scans are not the same as CT coronary angiography.

--The lack of "need" for a procedure does not equate to the absence of disease.

The power of heart scans is that they can uncover evidence for coronary atherosclerotic plaque 10 years before a cardiac disaster strikes. Witness Tim Russert's heart scan score of 210 in 1998 at age 48. 10 years later, you know what happened.

Beware the camipaign of misinformation and ignorance that continues that is hell-bent on maintaining the procedural status quo or locking us into a "drugs for all" mentality.

What's worse than sugar?

16. September 2008 William Davis (11)

There are a number of ways to view the blood sugar-raising or insulin-provoking effect of foods.

One way is glycemic index (GI), simply a measure of how high blood sugar is raised by a standard quantity of a food compared to table sugar. Another is glycemic load (GL), a combination (multiplied) of glycemic index and carbohydrate content per serving.

Table sugar has a GI of 65, a GL of 65.

Obviously, table sugar is not good for you. The content of white table sugar in the American diet has exploded over the last 100 years, totaling over 150 lb per year for the average person. (Humans are not meant to consume any.)

What is the GI of Rice Krispies cereal, organic or not? GI = 82-- higher than table sugar. GL is 72, also higher than table sugar.

How about Corn Flakes? GI 81, GL 70--also both higher than sugar.

How about those rice cakes that many dieters will use to quell hunger? GI 78, GL 64.

How about Shredded Wheat cereal? GI 75, GL 62.

All of the above foods with GI's and GL's that match or exceed that of table sugar are made of wheat and cornstarch. Some, like Shredded Wheat cereal and rice cakes, don't even have any added sugar.

Stay clear of these foods if you have low HDL, high triglycerides, high blood sugar, or small LDL. Or, for that matter, if you are human.

Keep the eloquent words of New York University nutritionist, Marion Nestle, author of the book, Food Politics, in mind:

“Food companies—just like companies that sell cigarettes, pharmaceuticals, or any other commodity—routinely place the needs of stock holders over considerations of public health. Food companies will make and market any product that sells, regardless of its nutritional value or its effect on health. In this regard, food companies hardly differ from cigarette companies. They lobby Congress to eliminate regulations perceived as unfavorable; they press federal regulatory agencies not to enforce such regulations; and when they don’t like regulatory decisions, they file lawsuits. Like cigarette companies, food companies co-opt food and nutrition experts by supporting professional organizations and research, and they expand sales by marketing directly to children, members of minority groups, and people in develop countries—whether or not the products are likely to improve people’s diets.” ??

Are sterols the new trans fat?

13. September 2008 William Davis (16)

By now, I'm sure you're well-acquainted with the hydrogenated, trans fat issue.

Hydrogenation of polyunsaturated oils was a popular practice (and still is) since the 1960s, as food manufacturers sought a substitute for saturated fat. Bubbling high-pressure hydrogen through oils like cottonseed, soybean, and corn generates trans fatty acids. These man-made fatty acids, while safe in initial safety testing, proved to be among the biggest nutritional mistakes of the 20th century.

Trans fatty acids have been associated with increased LDL cholesterol, reduction in HDL, oxidative reactions, abnormal rigidity when incorporated into cell membranes, and cancer. Trans fats still dominate many processed foods like chips, cookies, non-dairy creamers, food mixes, and thousands of others. They're also found prominently in fast foods.

Fast forward to today, and most Americans have become aware of the dangers of trans fats and many try to avoid them.

But I worry there is yet another substance that has worked its way into the American processed food cornucopia that has some potential for repeating the trans fat debacle: sterol esters.

Sterols are naturally-occurring oils found in vegetables, nuts, and numerous other foods in small quantities. Most of us take in 200-400 milligrams per day just by eating plant-sourced foods.

Curiously, the chemical structure of sterols are very similar to human cholesterol (differing at one carbon atom). Sterols, by not fully understood means, block the intestinal absorption of cholesterol. Thus, sterol esters, as well as the similar stanol esters, have been used to reduce blood levels of total and LDL cholesterol.

So far, so good.

The initial commercial products, released in the late 1990s, were Take Control (sterol) and Benecol (stanol), both of which were marketed to reduce cholesterol when 2-3 tbsp are used daily, providing 3400 – 5100 mg of sterol or stanol esters, about 10- to 20-fold more than we normally obtain from foods. Several clinical trials have conclusively confirmed that these products reduce cholesterol levels.

They do indeed perform as advertised. Add either product to your daily diet and LDL cholesterol is reduced by about 10-15%. In fact, in the original Track Your Plaque book, these products were advocated as a supplemental means of reducing LDL when other methods fell short.

In 2008, there are now hundreds of products that have additional quantities of sterol esters in them, such as orange juice, mayonnaise, yogurt, breakfast cereals, even nutritional supplements. Most of these products proudly bear claims like "heart healthy." Stanol esters have not enjoyed the same widespread application. (I believe there may be patent issues or other considerations. However, it's the sterols that are the principal topic here, not stanols.)

Now, here's where it gets a bit tricky. There is a rare (1 per million) disease called sitosterolemia, a genetic disorder that permits the afflicted to absorb more than the usual quantity of sterols from the intestine. While you and I obtain some amount of sterols from plant-based foods, absorption is poor, and we absorb <10% of sterols ingested. However, people with sitosterolemia absorb sterols far more efficiently, resulting in high blood levels of sterols that result in coronary disease and aortic valve disease, with heart attacks occurring as young as late teens or 20s. Treatment to block sterol absorption are used to treat these people.

There are also a larger number, though still uncommon (1/500) of people who have only one of the two genes that young people with sitosterolemia have. These people may have an intermediate capacity for sterol absorption.

Okay, so what does this have to do with you? Well, if you and I now take in 10-20 times greater amounts of sterol esters, do our blood levels of sterols increase?

Several studies now suggest that, yes, sterol blood levels increase with sterol ingestion. One study from Finland, the STRIP Study, showed that children who had double usual sterol intake increased blood levels by around 50%.

Similarly, a Johns Hopkins study in adults with only one of the genes ("heterozygotes") for sitosterolemia increased sterol blood levels by between 54-116% by ingesting 2200 mg of sterols added per day, despite reduction of LDL cholesterol levels.

Even people with neither gene for sitosterol hyperabsorption can increase their blood levels of sterols. But the crucial question: Do the blood levels of sterols that occur in unaffected people or in heterozygotes increase the risk of coronary heart disease? The answer is not known.

Despite the several clinical trials performed with sterol esters, all of them have examined LDL and total cholesterol reduction as endpoints, not cardiovascular events. It is conceivable that, while sterol esters reduce cholesterol, risk for heart disease is increased due to higher blood levels of sterols.

The question is not settled. For now, it is just a suspicion. But that's enough for me to steer clear of processed foods supplemented with these uncertain sterol esters. My previous recommendations for sterol ester products will be removed with the next edition of Track Your Plaque. Until we have solid evidence that there are no adverse cardiovascular effects of sterol esters, in my view they should not be part of anyone's heart-disease prevention program.

(The same argument does not seem to apply to stanol esters, such as that contained in butter-substitute Benecol, since stanol esters are not absorbed at all and remain confined to the intestine.)

The Diabetes Gold Rush

11. September 2008 William Davis (9)

Lou came into the office. Clearly, his program had gone sour.

Lou had initially obtained wonderful control over his heart scan score of 1114, having reversed modestly in his first three years of effort through correction of his multiple causes (including low HDL, severe small LDL, Lp(a), and a diabetic tendency).

But Lou now came into the office red-faced and sporting a big bulging abdomen. Blood sugar? Now in the overtly diabetic range. Lou said that his primary care doctor had suggested that he start on three new medications (glucophage, injectable Byetta, and Actos) to control his blood sugar. His doctor also told him to increase his intake of fibers by eating more "healthy" breakfast cereals like Cheerios.

Lou had apparently done just that (added "healthy" fiber-rich foods) even before his doctor had suggested it. (Lou failed to remember the several conversations we'd had about healthy eating.) Unfortunately, Lou also failed to connect his increased intake of "healthy fiber-rich foods" and his growing abdominal girth (his "wheat belly").

Here's the dirty little secret: Much of the world wants you to be diabetic. It is the health gold rush of this century. "Go West, young man!"

To find out what I mean, you need only ask: Who profits when people become diabetic? That's easy:

The pharmaceutical industry--Diabetes is a booming growth industry, a source of tens of billions of dollars of revenue, poised for enormous growth as the population ages and gets fatter. It is common for a newly-diagnosed diabetic to be given new prescriptions for two or three drugs with a monthly cost of $300. Of course, the chronic nature of the disease make this far more profitable than, say, a two week course of antibiotics. Presently, 70 new drugs are under development.

Diabetes drug maker Novo Nordisk reported a 25% increase in revenues in 2007 from diabetic agents in the North American market, along with near $2 billion increase in profit for the year. Merck's recently-released DPP-4 inhibitor, Januvia, has already sold $668 million in 2007 and is growing rapidly.

The medical device and supply industry. Take a look at the Medtronic quarterly earnings report, detailing the breakdown of their record-setting quarterly revenue of $3.7 billion:

Diabetes revenue of $269 million grew 12 percent driven by sales
of consumables, the accessories required by insulin pump users, and
continuous glucose monitoring products. Revenue from international
sales grew 31 percent over the same quarter last year.

That's what I call a growth industry.

The processed food industry. The food industry is as big or bigger than the drug industry. ADM, Kraft, General Mills all have annual revenues in the $12-50 billion range. There are plenty of others.

When we're told, for instance, that Cheerios reduces cholesterol, we're not told that it skyrockets blood sugar or triggers small LDL. When we're sold whole wheat crackers, Cocoa Puffs (which the American Heart Asscociation says is heart-healthy), or granola bars, hunger is stimulated, impulse to eat more grows, blood sugar escalates, we get fat, we get diabetic. It's a simple formula.

So be aware that there is little incentive among corporate giants in the food, medical device, or drug industries to encourage behaviors that decrease the incidence of diabetes. In fact, there is enormous financial incentive to make sure that diabetes continues to grow at the startling rate it has over the last decade.

To be sure, the drug and medical device industry will also develop better tools to deal with diabetes and its complications. But the very best way to deal with diabetes is to not develop it in the first place.

What else is there?

7. September 2008 William Davis (11)

This question comes up frequently:

Aren't there any alternatives to heart scans performed on a CT or EBT device?

Yes, there are.

First of all, heart scans are performed best on an electron-beam CT device (EBT) or a 64-slice multi-detector CT (MDCT) device. (While they are also obtainable through less-than-64 slice CT devices (e.g., 16 slices and less), I would advise against it because of the excessive radiation exposure and poor accuracy.) CT heart scans are not to be confused with now more popular CT coronary angiograms, which are performed on the same devices but require intravenous x-ray dye and many times more radiation.(See CT scans and radiation exposure and Heart scan frustration.) Heart scans currently form the basis for the Track Your Plaque program, a program of tracking plaque in the hopes of stopping or reversing the otherwise inevitable 30% per year increase.

Let's confine our discussion to people without symptoms, meaning people like you and me sitting at home, not in an emergency room having chest pain or other similar acute symptomatic presentation.

Among the other ways to uncover hidden coronary plaque:

--Heart catheterization--to yield a coronary angiogram. Yes, this does tell us whether coronary plaque is present. However, it is invasive, expensive, and crude. (I've performed 5000 over my career; they are crude, though useful, tools in acute settings like unstable symptoms or heart attack, a different situation.) Coronary angiography is also non-quantitative. While they provide a value like "40% blockage mid-way in right coronary" or "90% blockage in left anterior descending" they do not provide a trackable lengthwise index of total plaque volume. Identifying severe blockages in people with symptoms leads to stents, bypass surgery and the like, but it is not practical nor of long-term usefulness in apparently, healthy people without symptoms.

--Carotid ultrasound--Here's is where a lot of confusion comes from. Standard carotid ultrasound (U/S) performed in virtually every hospital and many clinics will yield crude qualitative results, e.g., "16-49% stenosis (blockage) in right internal carotid artery". The crude value range is because much of carotid U/S is based on flow velocities, not just direct visualization of the plaque itself ("2-D imaging). However, if carotid stenosis of any degree is identified, the likelihood of silent coronary plaque is much greater.

Limitations: The qualitative, non-quantitative nature of carotid U/S make it difficult to follow long-term in a precise way. Also, this is carotid plaque, not coronary plaque. It makes it very difficult to follow carotid plaque as an indirect means of tracking coronary plaque. The two arterial territories, carotid and coronary, do not track together: there are divergences in many people, with carotid plaque absent in some people with advanced coronary plaque, carotid plaque more susceptible to different risk factors than coronary. So carotid U/S is helpful for its own purposes, but not terribly helpful for coronary tracking.

How about carotid intimal-medial thickness (CIMT) obtained also with carotid U/S? CIMT is a useful index of bodywide atherosclerosis. CIMT is simply a measure not of plaque (and is measured in regions of the carotid artery away from plaque), but of the thickness of the lining of the carotid arteries. Everybody has a measurable CIMT, but it thickens as atherosclerosis grows. CIMT is a radiation-free test that takes several minutes.

Limitations: Hardly anybody does it outside of research protocols. I know of no hospital or clinic in my area that performs CIMT, though it is slowly being adopted in some centers. It is also difficult to rely on repeated tests, because there is substantial variation when one technologist or another performs it. CIMT is also a flawed index of coronary plaque. When CIMT is compared to heart scan scores, CT coronary angiography, or conventional coronary angiography, CIMT correlates about 60-70% with the degree of coronary atherosclerosis.

CIMT is therefore a useful test for research, but a distant 2nd choice--if you can obtain it.

--Ankle-brachial index (ABI)--ABI is a crude measure, simply a comparison of the blood pressure (obtained with a blood pressure cuff) in the legs divided by blood pressure in the arms. The ratio is called ABI. Any ABI <1.0, meaning less pressure in the legs compared to the arms, is indirectly indicative of advanced coronary disease. ABI is, in fact, a very powerful predictor of cardiovascular events. If ABI is <1.0, your future risk for heart attack is very high, even in the absence of symptoms.

Limitations: The vast majority of people with heart disease, even those having undergone stents or bypass surgery, have normal ABI's. Virtually all people with high heart scan scores have normal ABI's. In other words, ABI is a measure of very advanced atherosclerosis only.

--Stress tests--I lump all stress tests together in their various forms, e.g., stress thallium, stress Cardiolite, stress Myoview, persantine/adenosine Cardiolite, dobutamine echocardiography, etc. Stress tests are tests of coronary blood flow, not of plaque. Stress tests are useful in people with symptoms, like chest pain or breathlessness, since stress tests are provocative tests that can help determine whether reduced coronary blood flow is the cause behind a symptom, or whether hiatal hernia, esophagitis, gallstones, pleurisy, musculoskeletal causes, or some other process is behind symptoms.

Limitations: Stress test are virtually useless in people without symptoms. This is why people like Tim Russert and Bill Clinton, both without symptoms, underwent several (Russert 3, Clinton 5) nuclear stress tests---all normal. You know what happened to them. Stress tests do not reliably uncover hidden coronary plaque in people without symptoms. Stress tests are, like coronary angiograms, non-quantitative. They are normal or abnormal.

Outside of experimental settings, that's it.

You can probably see why I advocate CT heart scans for tracking plaque. I do not advocate heart scans because I sell them (I don't), because scan centers pay me to say these things (they don't, and in fact my relationship with my usual heart scan centers has become deeply contentious, though I still endorse the technology). I say that heart scans are superior because they are, in 2008, the only way to 1) identify and 2) track coronary plaque that is easy, safe, low-radiation, and reasonably priced (<$200 in Milwaukee at 5 centers).

The need for a technology that allows tracking of plaque, not just initial identification, is also an important distinction. People who've had some measure of atherosclerosis all catch on to this eventually. "Can I reverse it?" is an inevitable question once the disease is identified in some way. So a tool for tracking over time to gauge the success or failure of a program of prevention can be assessed.

Perhaps in 10 years, another technology will emerge as the preferred means to do the same, but better. If that proves true, we will convert to that technology. But today heart scans performed on CT heart scans are the only rational way to both detect, then track, coronary atherosclerotic plaque.

Let's gamble with your health

5. September 2008 William Davis (4)

Let's play a game.

I'm going to list some lipid patterns and you tell me whether or not the person with these values has heart disease.

Patient 1

Total cholesterol 150 mg/dl
LDL cholesterol 75 mg/dl
HDL 50 mg/dl
Triglycerides 125 mg/dl

Patient 2

Total cholesterol 300 mg/dl
LDL cholesterol 200 mg/dl
HDL cholesterol 35 mg/dl
Triglycerides 325

Patient 3

Total cholesterol 300 mg/dl
LDL cholesterol 100 mg/dl
HDL cholesterol 25 mg/dl
Triglycerides 875 mg/dl

Let's say that any one of these profiles is yours. Should you be getting your affairs in order, preparing for your cardiac catastrophe? Should you demand a stress test from your doctor, hoping that it will shed some light on your dilemma? Should you go ahead and go to the all-you-can-eat rib restaurant, content that you will be attending your granddaughger's wedding in 2020 in full health?

If you can tell, you're a lot better at this than I am.

I provide consultation to other physicians and patients on complex hyperlipidemias in my area. In other words, if someone has a difficulty to manage lipid disorder, the doctor sends the patient to me.

Managing these wildly variable values is the easy part. Deciding whether or not heart disease is concealed within the patient . . . well, that's the hard part.

Let's take it a step further: Suppose all three profiles also have 50% of all LDL particles as the abnormal small particles. And they all have a lipoprotein(a) level of 50 mg/dl, an abnormally high level.

How about now: Can you tell whether any or all of these people have hidden heart disease?

What if they are 20 years old? Does that make a difference?

What if they are all females over 65 years--how about now?

If the only tool you have to divine the presence of hidden heart disease is a lipid panel, or even a lipoprotein panel, then the best you can manage is to hazard a guess based on statistical probability. You also assume that this "snapshot" represents the sorts of values someone has had for their entire lives. You cannot factor in the fact that the first person gained 60 lbs in the last three years since completing menopause. You can't factor in that patient 2 smoked two packs of cigarettes a day for 25 years, but quit 10 years ago.

It's also foolhardy to believe that every known cause of heart disease is currently identifiable and revealed by modern-day blood testing.

A heart scan is simply a means to quantify the sum-total of risk factors--causes--that have exerted an effect up until the moment of your scan. It will reveal the quantity of coronary atherosclerotic plaque present, regardless of whether you stopped smoking 20 years ago or lost 30 lbs last year.

For these reasons, nothing can replace the value of quantifying plaque: not cholesterol, not the Framingham risk calculation, not measures of small LDL or lipoprotein(a), not the presence or absence of symptoms. In 2008, the method of choice for measuring plaque remains a CT heart scan. Perhaps in 10 years it will be some other method.

As always, let me remind Heart Scan Blog viewers that I make this point NOT to sell heart scans, which I have no reason whatsoever to do. I say this because we require a tool to track this potentially fatal disease. We require a yardstick for tracking progression or regression. The only tool that suits these purposes in 2008 is a CT heart scan.

Who knows what

4. September 2008 William Davis (4)

You know that cynical old saying:

It’s not what you know, it’s who you know.

In other words, knowing the right person provides you strategic advantage in business, social advancement, etc.

In health, it was often true. Knowing who the better doctors were, for instance, in your city might provide you with access to better care.

Enter the Information Age. You now have access to medical information equal to that of your doctor. You now have access to patient discussions about doctors, their practices, their performance records. There is now a depth and breadth of information on health that was never available before.

I’d therefore turn the old saying into the new Health 2.0 version:

It’s not who you know, it’s what you know.

In health, information now reigns supreme, not knowing somebody else who has the right connections.

Positive: Everybody now theoretically has access to an equal amount of information, since you can access information on any topic just as easily as I can.

Negative: It puts more of the burden on you. If you screw up in health, perhaps you didn’t try to get the best information hard enough.

I love this new development, this emergence of empowerment in health. I call it self-directed health, the individual capacity to exert enormous influence over the quality of your healthcare.

This is obviously a work in progress. All the answers and tools for self-directed care, self-empowerment are not yet available, some haven’t even yet been imagined.

But they are coming.

“Too many false positives”

4. September 2008 William Davis (6)

“Do you really think I need a heart scan?” asked Terry.

“My doctor said that heart scans show too many false positives. He says that many people end up getting unnecessary heart catheterizations because of them.”

At age 56, Terry was becoming increasingly frightened. His father had suffered his first heart attack at age 53, Terry’s paternal uncle had a heart attack at age 56, his paternal grandfather a heart attack at age 50.

Is this true? Do heart scans yield too many false positives, meaning abnormal results when there really is no abnormality?

No, it is not. What Terry’s doctor is referring to is the fact that, in the decades-long process that leads to heart attack, heart scans have the ability to detect early phases of developing coronary atherosclerotic plaque.

Let’s take Terry’s case, for example. Given his family history, it is quite likely that he does indeed have coronary atherosclerotic plaque. Will it be detectable by performing a stress test? Probably not. In fact, Terry jogs and feels well while doing so. While a stress test abnormality that fails to reach conscious perception is possible, it’s fairly unlikely given his exercise routine.

Will Terry’s coronary atherosclerotic plaque be detectable by heart catheterization? Very likely. But why perform an invasive hospital procedure just as a screening test? Should a woman wishing to undergo a screening test for breast cancer undergo breast removal? Of course not.

Is waiting for symptoms a rational way to approach diagnosis of heart disease? Well, when symptoms appear, it means that coronary blood flow is reduced. Stents and bypass surgery may be indicated. The risk of heart attack and death skyrocket. Sudden death becomes a real possibility.

In the 30 or so years required to establish sufficient coronary plaque to permit the appearance of symptoms or the development of an abnormality detectable by stress testing, there were many years when the disease was early--too early to generate symptoms, too early to be detectable by stress testing.

That’s when heart scans uncover evidence for silent coronary atherosclerotic plaque.

Should we call this a “false positive” just because it doesn’t also correlate with “need” for a catheterization, stent, bypass operation or result in heart attack within the next few weeks?

The detection of early plaque is just that: early disease detection.

Imagine, for instance, that the breast cancer that will grow into a palpable nodule or mass detectable by mammogram is detectable by a special breast scan 15 years before it becomes a full-blown tumor, metastasizing to other organs. What if effective means to halt that earliest evidence of cancer could put a stop to this devastating disease decades ahead of danger? Is this a “false positive” too?

In my view, this is the knuckleheaded thinking of the conventional practitioner: “Don’t bother me until you’re really sick.” Prevention is a practice that has become fashionable only because of the push of the drug industry. Nutrition is an afterthought, a message conceived through consensus of “experts” with suspect motivations and allegiances.

So, no, heart scans do not uncover “false positives.” They uncover early disease--true positives--years before it is detectable by standard tests or by the appearance of catastrophe. But that is the whole point: Early detection means getting a head start on prevention.

Do heart scans lead to unnecessary heart catheterizations? Yes, sadly they do. But not because heart scans are false positive. It happens because of unscrupulous or ignorant cardiologists who use the information wrongly. In my view, heart scans should NEVER lead directly to heart catheterization in an asymptomatic patient. Heart scans, as helpful as they are, do not modify the standard reasons for performing heart procedures.

If a car mechanic is dishonest and fixes a carburetor that didn't need fixing, should we condemn all car mechanics? No, of course not. We only need to develop the means to weed out the bad apples. The same applies to heart scans.

Triglycerides divided by five

3. September 2008 William Davis (8)

Here's a bit of lipid tedium that might nonetheless help you one day decipher the meaning of shifts in your cholesterol panel.

Recall from prior discussions that conventional LDL cholesterol is a calculated value. Contrary to popular opinion, LDL is usually not measured, but calculated from the Friedewald equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

For the sake of simplicity, let's call total cholesterol TC; HDL cholesterol HDL, and triglycerides TG.

We've also talked in past how a low HDL makes calculated LDL inaccurate, sometimes wildly so. (See Low HDL makes Dr. Friedewald a liar.)

Here's yet another source of inaccuracy of the Friedewald-calculated LDL: any increase in triglycerides.

Let's say, for instance, that starting lipid panel shows:

TC 170 mg/dl
LDL 100 mg/dl
HDL 50 mg/dl
TG 100 mg/dl

You're advised to follow a standard low-fat, whole grain-rich diet advocated by "official" agencies (the diet I bash as knuckleheaded). Another panel a few months later shows:

TC 230 mg/dl
LDL 140 mg/dl
HDL 50 mg/dl
TG 200 mg/dl

(Obviously, I've oversimplified the response for the sake of argument. HDL would likely go down, LDL would change more depending on body weight, small LDL tendencies, and other factors. You'd also likely get fat.)

Now your doctor declares that your LDL has gone up and you "need" a statin agent.

Nonsense, absolute nonsense.

What has really happened is that the increased dietary intake of wheat and other "healthy whole-grain foods" has caused triglycerides to skyrocket. LDL increases, in turn, by a factor of TG/5, or 40 mg/dl. Thus, LDL has been inflated by the triglyceride-raising effect of whole grains.

This is yet another reason why the standard lipid panel, full of hazards and landmines, needs to be abandoned. But calculated LDL in particular is an exercise in frustration.

Though the example used is hypothetical, I've witnessed this effect thousands of times. I've also seen many people placed on statin drugs unnecessarily, due to the appearance of a high LDL cholesterol that really represented increased TG/5, usually induced by an excessive carbohydrate intake, including those commonly misrepresented as healthy such as whole grains.

Who reads The Heart Scan Blog?

2. September 2008 William Davis (0)

In the Heart Scan Blog, I am often guilty of speaking out loud of my varied thoughts on this crazy thing that we've created called the cardiovascular healthcare machine. But I discuss it in the context of asking "How could this be done better--better outcomes, more patient-friendly, more accessible . . . more do-it-yourself?

The last part is the part that throws most people. Do-it-yourself? My colleagues would claim I'm nuts, suggesting that coronary heart disease is something manageable by yourself. In the conventional pathway, after all, coronary disease is that unpredictable, poorly detected by standard tests, condition that then leads to heart catheterization, stents, bypass , and the like.

Several factors distinguish the readers of The Heart Scan Blog that surprised me:

--Nearly 60% are women
--There are a disproportionate number of Asian people. (Can someone explain this to me?)
--A great number have graduate degrees

I believe this tells me that The Heart Scan Blog appeals to a somewhat more sophisticated audience. This, to some degree, warms my heart, since it means that I've captured the attention of some people who may be more discriminating and thoughtful in their Internet surfing.

However, I also lament the fact that these conversations are not achieving the mainstream. After all,

Cureality | Real People Seeking Real Cures

Are Your Cosmetics Safe?

11. June 2014 Dawn D (0)

If you are reading The Cureality blog chances are you care about your health. You care about what you eat. You want to remain healthy, free of disease, feel good and possibly even want to look and feel as vibrant as you were when you were 20. Many of us think of food all day long. Many of us love to eat. We plant gardens so we know our food is free of pesticides and other toxic chemicals. Food can be a cause of disease and it can minimize our chances of disease. We try and take care of our insides but did you ever wonder what in the world you apply to your skin on a daily basis? What do these products contain and are they safe? Why are there more endocrine disorders popping up. Could it be that some of things we apply to our skin every single day may be harmful to our insides?

A portion of the skin health section of Cureality will take a look at skincare products and cosmetics. Are the products we apply to our skin gluten-free, paraben-free and free of other harsh chemicals that can cause skin irritations and possible other unwanted diseases. I came across Mirabella cosmetics and I wanted to learn more about this particular product line so I tracked down John Maly, founder and CEO of Mirabella Cosmetics. Mr. Maly was gracious enough to take time out and answer my questions.This is what Mr. Maly has to say about Mirabella:

DD: Tell us about some key features about Mirabella, gluten-free cosmetics. What made you get started in a gluten-free line?

JM: We didn't start as gluten-free. Over time we have continued to make our line more beautiful AND more healthy for women. First we began with a mineral foundation. Then as we introduced new products, we made sure they were as clean and healthy, while still being fashion forward. We saw the benefits to our clients to take out those ingredients that didn't help them look and feel their best such as glutens, parabens and talcs.

DD: Some cosmetic companies carry partially gluten-free cosmetics. Are all of Mirabella products gluten-free, paraben-free and talc-free?

JM: Everything is paraben-free and talc free. And our brand is all gluten-free except our Skin Tint Creme foundation. That is a product that women love and we just cannot make the formula without a wheat protein to perform as well...yet! We will continue to work on it!

DD: Are there other ingredients in cosmetics that women should be cautious of using if they have skin sensitivities or allergies?

JM: Some women are sensitive to fragrance as well.This is another thing that we avoid with our brand. The biggest ingredients that women find that helps with their skin health is mineral products. They are natural and very breathable on a woman's skin.

DD: I think your velvet lip pencils are by far the most extraordinary lip pencil on the market. What are some of your other standout products your customers love?

JM: Pure Press Mineral Foundation is still our #1product. But the fastest growing product is Magic Marker Eyeliner. It is easy to use, doesn't smudge and lasts all day.

DD: Anything new on the horizon for Mirabella that you can share with us?

JM: In August we launch CC crème. This product has all the good for you ingredients to help with Anti-Aging like avocado oil, argan oil and Acai (Assai) berry. Plus it is a mineral formula, gluten-free, and paraben-free. And it has an SPF of 20. One of the biggest issues that women have with aging is lips. That is why we put Litchi Chinesis Fruit Extract in our Colour Vinyl lipstick. Then in your favorite Velvet Lip Pencil, we put Pomegranate Extract, Vitamin C and E in to assist with in Anti-Aging.

DD: Is Mirabella only sold in the US or do you have international distribution as well.

JM: We are sold in Canada, Australia, Finland and Russia.

DD: Where can we purchase your cosmetics?

JM: Our products are available at www.mirabellabeauty.com and at over 1,500 of the finest salons and spas. Go to our salon locator to find a retailer near you.

Keeping Up with the Kids

5. June 2014 Amber B (0)

On Saturday my husband and I took our niece Anna out her annual birthday date. That date started with a trip to the Humboldt park playground. As with most kids, Anna ran straight to the spider-web jungle gym which I have to admit it looked pretty cool. Just before she began to climb up, she turned to look at me and said “Auntie Amber, climb up too!”

I was not wearing my playground apparel on Saturday. I had a cute pair of pink loafers on, skinny jeans, tank and a jean jacket. But it did look like fun so I decided to climb. No problems yet. I was good to go climbing around on the ropey, spider web apparatus. But of course, just climbing around was not enough. Anna suggested that we should race. Not just to the top, but to the top of the jungle gym over the side, across the rope bridge and down the slide. This is when my skill was put to the test.

As you could have guessed, Anna smoked me during our race. Not only that, but the jean jacket was off and I was working up a sweat. Was I getting a workout from my 9-year-old niece? I think so. But we both were having so much fun. We continued to climb up and down the fake rock wall, monkey bars and run around the playground. It was a blast.

But as I looked around the playground, I was the only adult climbing around the playground and playing. The other adults were sitting on park benches watching. One parent near by had to decline the request of a child they were with to join them on the playground equipment. I felt really good that I could be there with my niece running around, climbing and swinging.

Keeping up with our kids, grandkids, nieces and nephews is really important as we age. Otherwise we sit on the sidelines. How do you train for the playground? Get in the weight room. Lift heavy things, jump, pull yourself up, move side ways, and challenge your body to do movements beside sitting or standing. If it’s been awhile or you’re just not sure where to start then get a trainer and join some group workouts.

It’s time to get moving. Because it starts out at the playground now but soon it will be mud runs, Frisbee, triathlons and weekend football games. You need to keep up!

4 Tips to Boost Kids Veggie Intake

3. June 2014 Lisa G (0)

Vegetables are arguably the most important food group, the key to any healthy diet. They are one of the most nutrient dense food groups and serve the foundation to healthy meals and snacks. A frequent comment from people enjoying the Cureality way of eating is, “I am eating more vegetables than I ever have in my life!”

This is great because plentiful consumption is associated with decreased heart disease, reduced weight, lower blood pressure, glowing skin and decreased risk of some cancers. However, perhaps you’re reading this and feeling great that you eat your veggies but struggle to get your kids to do the same. If you are a parent, who is simply trying to provide nutritious options to your kids, give these tips a try.

1. Add cheese or butter to enhance flavor and increase the absorption of fat soluble vitamins A, D, E and K. Younger kids like to dip foods, so often pairing with a dip, such as hummus, can increase intake.

2. Try the “rule of 15” — putting a food on the table at least 15 times to see if a child will accept it. Don’t give up after a few attempts. This can indeed be frustrating, but have patience and continue to offer a small portion to expose children to veggies without forcing intake. Often parents feel like it’s their job to just make their children eat something. I suspect most children will always select apple pie over an apple. It is important to set the stage, at an early age, with what is offered. In addition, being a good food model is important. You can’t expect your child to try broccoli, if you make negative comments about its taste, texture or smell.

3. Once a food is accepted, parents should use “food bridges,” finding similarly colored or flavored foods to expand the variety of foods a child will eat. If a child likes pumpkin pie, for instance, try mashed sweet potatoes and then mashed carrots. If a child loves corn, try mixing in a few peas or carrots. Even if a child picks them out, the exposure to the new food is what counts.

4. Allow children to engage, as able. When grocery shopping or offering a snack, ask your child which option they would like to eat (e.g. ask which healthy foods they would prefer, blueberries or strawberries, cucumbers or carrots, etc.). When children are included in more food decisions it can decrease resistance. Include children in age appropriate preparation, as well, for example cutting produce, making a vegetable soup, or selecting produce at the grocery store.

When is the Best Time of Day to Workout?

2. June 2014 Amber B (0)

There are various theories about the best time of day to workout. At the personal training studio I own, training sessions start as early as 5:45am and the latest sessions start at 8pm. We have people that get up early and get their workout done first thing in the morning. We also have other people that get it done after work to release the stress of the day.

So which group is getting the better workout?

If you’re an early bird or have too many evening commitments then a morning workout is ideal for you. Here are some benefits to training in the morning.

1. Very few things can get in the way when you workout in the morning. (Except for the snooze button.) Later in the day extra phone calls, meetings and tasks can get in the way of getting your workout done.

2. After a strength or interval training session, your metabolism is elevated for hours after your workout. Enjoy these post exercise benefits while you are awake and active instead of when you are at rest.

3. Exercise will boost your energy. Use the momentum from a morning workout to arrive at work energized, present and focused instead of feeling sluggish because you just got out of bed.

4. Exercise on an empty stomach before breakfast is a great way to burn more body fat. Upon waking, the body is in a fasted state. Without ready available glucose in the bloodstream, the body is forced to use fat as an available fuel source for the workout.

However, some of us need our sleep or need to burn off the steam of a hectic workday. Here are some of the benefits of working out in the evening.

1. Getting enough sleep is crucial for health and recovery. If you have to skimp on regular sleep to get up for an early workout, the benefits of the workout start to diminish.

2. Instead of taking that stress of work home, you hit the gym after work. Even after the worst workdays, exercise will boost your mood. Friends and family will be grateful that you get your workouts (aka therapy session) completed.

3. Often people feel stronger when they workout in the evenings. When performing strength tests people tend to lift heavier during evening workouts. This could be due to the fact that they are more awake or that they have food fuel to utilize during their exercise session.

4. Research shows that you can build more muscle with evening workouts because cortisol levels are lowest in the evening. The result of this will be a higher testosterone to cortisol ratio leading to a less catabolic workout.

So which time of day comes out on top for the best workout time? In my opinion, it’s the time that you can do consistently. It’s the time that works best with your natural energy rhythms, work schedule, and family commitments.

Experiment working out at different times to see what works best for you. When you find the right fit, schedule your workouts on your calendar to build the exercise habit.

What is Cureality all about?

27. May 2014 William Davis (1)

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

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

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

Two weeks later:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

That’s why we developed Cureality.

How Can I Lose Weight Eating Fat?

26. May 2014 Lisa G Carbohydrates, Lipids, Nutrition (0)

For new comers to the Cureality nutrition approach, this question may invariably pop up. For many years, fats and oils, whether classified as good or bad, were demonized because they contain 9 calories per gram. Meaning, they contain more than twice the 4 calories per gram of carbohydrate or protein.

So this familiar logic stated, if you eat less fat, which by default meant more carbohydrate, you would eat fewer calories and lose weight. This misguided logic was based on the assumption that caloric density was the primary reason people either gained or lost weight. The result - obesity rates have climbed and low-fat diet recommendations have proven unsuccessful in thwarting the battle of the bulge.

Why? There are a multitude of reasons, as discussed in the Cureality Diet Track. The following two explanations are important to to avoid needlessly suffering on a low-fat diet.

1) Appetite satiation is drive by insulin response, not calorie density.

Meals that trigger a substantial insulin response trigger increased appetite and fat storage. Carbohydrates, such as whole grain bread, whole wheat waffles, and fruit juice trigger insulin release. Continuous insulin provocation equates to one heck of a time trying to lose weight, as insulin is a fat-storage hormone. In comparison, oils and fats are the least insulin provoking with protein a close second. Consuming adequate fat intake is essential to quench appetite and avoid the insulin surges and crashes that are the result of eating plenty of “healthy whole grains”.

2) Modern wheat increases appetite thereby increasing intake.

Portion control becomes a major challenge because the gliadin protein in modern wheat stimulates appetite to the tune of 400 calories more per day, 365 days per year. That’s a recipe for weight gain, not loss.

The Cureality nutrition approach encourages the generous use of healthy fats and oils to support healthy weight loss and cardiovascular health. These topics are discussed in much more detail in the Cureality Member Forum.

Drowning in a Sea of "Endocrine Disrupter Toxins"

20. May 2014 Chris K Drug advertising (1)

In my previous post I spoke about the close connection between gut health and thyroid health. Of course, as someone who lives with Hashimoto’s Thyroiditis I have a keen interest in anything related to the thyroid.

Just today, I came across an article revealing the 100 most-prescribed drugs in America and was stunned at what drug topped the list with more than 23 million prescriptions in 2013 – levothyroxine – the most commonly prescribed drug for treating hypothyroidism (but not necessarily the best in my opinion).

Some observers have warned about a pending epidemic of thyroid disorders. I believe the revelation of a thyroid drug as the most prescribed drug in America suggests that this epidemic is already a “fait accompli” (that’s French for the more colloquial expression “it’s a done deal!”).

I also believe it is due, in part, to the grim observations of experts like Dr. Davis who warn that we are literally “swimming in a sea” of endocrine disruptors, toxins that disrupt our hormonal glands such as the thyroid, adrenals, pancreas, ovaries, and testes. I would go farther to say we are drowning in that sea. Here are just a few examples of how ubiquitous and pervasive these toxins are.

Bisphenol A (BPA) in plastic containers has gotten a lot of bad press recently yet it still considered by the FDA to be safe in certain applications even though it has been shown to disrupt the sex glands and bind to thyroid receptors.

Triclosan is commonly used in hand-sanitizers and similar applications. Triclosan is known to decrease circulating levels of the thyroid hormone thyroxine (T4).

Polybrominated diphenyl ether (PBDE) is common used to make flame retardant clothing. PBDEs have been shown to disrupt both estrogen and thyroid hormones. The effects of PBDE exposure both in utero and shortly after birth can persist into adulthood.

Perfluorooctanoic acid (PFOA) in Teflon coated pots and pans and even microwave popcorn bags has been detected in the blood of more than 98% of the general US population. PFOA has implicated as both a carcinogen as well as an endocrine disruptor associated with thyroid disruption.

With all these “thyro-toxins” floating about it might not seem you like have a fighting chance to achieve thyroid health. But, the first step is to educate yourself - then take action. It is the essential sequence in what I call “Informed, Self-directed, Healthcare” (ISH).

Now that you have a better understanding of how to navigate the “thryo-toxin minefield” there are also positive steps you can take to stack the odds in favor of a healthy thyroid. If you participate in the Cureality program make certain to check out the Thyroid Health Track for a powerful list of proactive steps you can take.

Italian Food the Cureality Way

19. May 2014 Lisa G (0)

100% grain elimination is the theme that drives the Cureality nutrition approach. A common mistake made when eliminating grains is replacing wheat-based foods with gluten-free foods. Most gluten-free foods, as they are currently available in the supermarket, are made with rice starch, tapioca starch, cornstarch, and potato flour. These dried pulverized starches generate more insulin and blood sugar surges than wheat. Gluten-free foods made with these undesirable ingredients are free of the appetite stimulating gliadin protein and wheat germ agglutinin, a lectin protein unique to wheat that causes direct intestinal damage. However, at best they can be referred to as “less bad” or unwelcome additions to the diet. Increasing your intake of these junk carbohydrates is a recipe for weight gain, inflammation and sky high blood sugar.

When removing grains from the diet, the goal is to replace them with truly healthy alternatives that do not contribute to negative health consequences. There are several reasonable substitutions available that allow your favorite sauce and protein combos to shine in tasty pasta-like dishes. People following the Cureality nutrition approach frequently comment that they do not miss “real” pasta because of the available healthy replacements they have learned about and incorporated into their lifestyle.

Our nutritionist, Lisa G., is the champion at helping navigate this lifestyle. In this video, she demonstrates how to prepare spaghetti squash, which can be used to replace wheat-based pasta. In another video zucchini noodles are the star. Homemade meatballs, a zesty tomato sauce and zucchini “pasta” combine for a delicious meal. Who needs grains when you can enjoy meals that support increased energy and less joint pain?

Traveling, while being wheat-free and dairy-free. Can it be done?

16. May 2014 Dawn D Dairy products, Wheat-free (0)

Summer vacation is right around the corner. The temptation to deviate from your normal healthy eating habits may occur… but resist. So how in the world do you continue to eat The Cureality way when you're traveling internationally? Let me tell you how I do it. I would also like to add I am allergic to dairy and I avoid all wheat containing foods. This has been my way of life for years and actually is extremely simple for me to manage while away from my own kitchen.

I decided to pay Italy a visit. I knew I would be overwhelmed with wonderfully fresh smelling bakery, pasta, cheese, gelato, and pizza. All foods I either can't consume due to my dairy allergy or foods I choose to avoid because of their health effects.

I was correct in my food assessment: the grains, bakery, and gelato were in every nook and cranny I encountered. Food choices can be difficult while traveling but I ask numerous questions regarding ingredients and I am certainly not afraid to swap out french fries for grilled vegetables.

Here's what I did the first few days on vacation with my diet routine to minimize dietary booby traps:

Day 1:

Breakfast, Hmmmm….Italians like their bakery. WOW. Tough when most of the foods being served are grains and eggs with dairy mixed in. I had two hard boiled eggs, tomatoes, sausage and espresso.

Lunch: Arugula lettuce topped with a chicken breast, roasted peppers and tomatoes. A side of salmon and lots and lots of olive oil on top. Very tasty and filling with the olive oil.

Dinner: Hamburger (no bun) with tomato, mayo, lettuce topped with a mountain of sauteed spinach. Water and yes…Italian wine found it's place at the table.

Day 2:

Breakfast: I devoured two hard boiled eggs with lettuce, cucumbers, shredded carrots, tomato and pineapple slices. Two cafe Americanos and water.

Lunch: Lunch was spectacular: Beef tips, arugula, lettuce, shredded carrots, tomatoes, olive oil and raw salmon. Yes, I mixed it all together and it was fabulous. Plenty of water with the "frizzle."

Dinner: I'll be honest: I had a difficult time with this meal due to our location and choice of foods, but I managed. Another hamburger with no bun, salad with mixed vegetables, and a few potato wedges. Wine and water.

Day 3:

Breakfast: Hardboiled eggs were getting old. Nonetheless, I had two of them chopped with tomato. Deli meat--Italians love their deli meat as well. Cafe Americano and water.

Lunch: Seafood salad-shrimp, octopus and squid mixed with argulua, fresh tomatoes, cucumbers and olive oil. Water.

Dinner: One hefty salad with shrimp, pear slices, ginger, tomatoes, avocado and olive oil. Wine and water.

Day 4:
Breakfast: Scrabbled eggs/sauage and pineapple slices. Cafe Americano and plenty of water.

Lunch/Dinner: I had to combine these two meals today. I had a delicious meal of curried shrimp (I made sure there was no dairy in the curry sauce) and a very large plate of grilled vegetables. Wine and water.

My diet may not be the most lavish to some but I enjoy my choices. I'm confident I will have no troubles with the remainder of my vacation. I haven't eaten wheat for a number of years so I don't experience the craving for bakery, pasta, or pizza. Dairy, I simply have to avoid, because I truly experience ill-effects from consuming it. My experience with travel and food choices have always worked in my favor. Ask questions and resist putting on that 5-10 pounds of vacation weight.

Ciao-Ciao~
