What to eat: Part I

6. April 2010 William Davis (0)

I've spent a good number of Heart Scan Blog posts detailing what foods to limit or avoid.

The list of unquestionably bad foods to avoid include foods made of wheat, cornstarch, and sugars. Fructose is proving to be an exceptionally bad form of sugar, worse than any other. I've issued warnings about levels of carbohydrates that can be determined by postprandial testing.

In response to several requests to clarify what foods to eat, this post begins a series discussing what foods are good to eat.

I believe that a strong case can be made for eating vegetables in nearly all its varied forms, from cucumbers to peppers to leafy vegetables to eggplant to alliums like onions. The only form we avoid are red and white potatoes due to the blood sugar-increasing effects.

While this seems obvious, I am impressed how many people who follow low-carb diets find themselves following a high-animal product diet with vegetables as the sideline. It should be the other way around: A high vegetable diet with animal products as the sideline.

Vegetables are your principal source of:

1) Flavonoids and polyphenols--e.g., anthocyanins and catechins. All the recently appreciated effects of flavonoids and polyphenols highlight the wonderful effects of compounds originating in plant foods. This includes the anthocyanins and resveratrol in red wine; the catechins and epicatechins cocoa and green tea; the hydroxytyrosol, phenolic acid, and flavonoids of olive oil.

2) Fiber--Fiber is essentially a plant phenomenon, since there is virtually none in chicken, fish, and beef. The benefits of fiber are, I believe, undisputed. Neglecting fiber can, at the very least, lead to a nasty case of hemorrhoids. At the worst, it is related to various cancers, especially colon cancer.

3) Vitamin C--While vitamin C may be old and boring in light of new, exciting discoveries like flavonoids, neglect leads to bad things.

Vegetables are generally classified as carbohydrate foods, since they are low in protein and fat. But this is the source of carbohydrates you do not want to sacrifice in a low-carbohydrate diet. There's just too much good from vegetables.

Notice that I didn't say "fruits and vegetables." This is a fundamental mistake made by many: Oveconsumption of fruits. I've even seen people who follow an otherwise good diet develop diabetes--just from too much fruit.

Vegetables should be the cornerstone of the human diet. But I'll bet you knew that already.

Carbohydrates and LDL

4. April 2010 William Davis (16)

There's a curious and powerful relationship between carbohydrates and LDL particles. Understanding this relationship is crucial to gaining control over heart disease risk.

(Note that I did not say "LDL cholesterol"--This is what confuses people, the notion that cholesterol is used as a surrogate marker to quantify various lipoproteins, including low-density lipoproteins, LDL. I'm NOT interested in the cholesterol; I'm interested in the behavior of the low-density lipoprotein particle. There's a difference.)

Carbohydrates:

1) Increase triglycerides and very low-density lipoprotein particles (VLDL)
2) Triglyceride-rich VLDL interact with LDL particles, making them smaller. (A process mediated by several enzymes, such as cholesteryl-ester transfer protein.)
3) Smaller LDL particles are more oxidizable--Oxidized LDL particles are the sort that are taken up by inflammatory white blood cells residing in the artery wall and atherosclerotic plaque.
4) Smaller LDL particles are more glycatable--Glycation of LDL is an important phenomenon that makes the LDL particle more atherogenic (plaque-causing). Glycated LDLs are not recognized by the LDL receptor, causing them to persist in the bloodstream longer than non-glcyated LDL. Glycated LDL is therefore taken up by inflammatory white blood cells in plaque.

Of course, carbohydrates also make you fat, further fueling the fire of this sequence.

The key is to break this chain: Cut out the carbohydrates. Cut carbohydrates and VLDL and triglycerides drop (dramatically), VLDL are unavailable to transform large LDL into small LDL, small LDL is no longer available to become oxidized and glycated, blood sugar is reduced to allow less glycation. Voila: Less atherosclerotic plaque growth.

Yet the USDA, American Heart Association, and the Surgeon General's office all advise you to eat more carbohydrates. The American Diabetes Association tells you to eat 70 grams or so carbohydrates per meal. (Yes: Diabetes, the condition that is MOST susceptible to these carbohydrate effects.) Follow their advice and you gain weight; triglycerides and VLDL go up; calculated (Friedewald) LDL may or may not go up, but true measured LDL (NMR LDL particle number or apoprotein B) goes way up; small LDL is triggered . . . You know the rest.

The dance between carbohydrates and LDL particles requires the participation of both. Allow one partner to drop out of the dance and LDL particles will sit this dance out.

Strange but true: Part II

4. April 2010 William Davis (0)

Here's the second part of the Heart Scan Blog post I wrote a couple of years back describing the wacky origins of this thing that has so changed the face of heart care in the U.S., the cardiac catheterization.

Heart catheterization: Strange, but true

3. April 2010 William Davis (1)

It's a couple of years old, but this post from March, 2008, remains relevant.

It details the curious origins of heart catheterization, the procedure that has saved some lives, but also been responsible for the proliferation of unnecessary heart procedures.

The modern era of heart disease care was born from an accident, quirky personalities, and even a little daring.

The notion of heart catheterization to visualize the human heart began rather ignominiously in 1929 at the Auguste-Viktoria Hospital in Eberswalde, Germany, a technological backwater of the day. Inspired by descriptions of a French physician who inserted a tube into the jugular vein of a horse and felt transmitted heart impulses outside the body, Dr. Werner Forssmann, an eager 25-year old physician-in-training, was intent on proving that access to the human heart could be safely gained through a surface blood vessel. No one knew if passing a catheter into the human heart would be safe, or whether it would become tangled in the heart’s chambers and cause it to stop beating. On voicing his intentions, Forssmann was ordered by superiors not to proceed. But he was determined to settle the question, especially since his ambitions captured the interest of nurse Gerda Ditzen, who willingly even offered to become the first human subject of his little experiment.

Secretly gathering the necessary supplies, he made his first attempt in private. After applying a local anesthetic, he used a scalpel to make an incision in his left elbow. He then inserted a hollow tube, a catheter intended for the bladder, into the vein exposed under the skin. After passing the catheter 14 inches into his arm, however, he experienced cold feet and pulled it out.

One week later, Forssman regained his resolve and repeated the process. Nurse Ditzen begged to be the subject, but Forssmann, in order to allow himself to be the first subject, tricked her into being strapped down and proceeded to work on himself while she helplessly watched. After stanching the oozing blood from the wound, he threaded the catheter slowly and painfully into the cephalic vein, up through the bicep, past the shoulder and subclavian vein, then down towards the heart. He knew that simply nudging the rubber catheter forward would be sufficient to direct it to the heart, since all veins of the body lead there. With the catheter buried 25 inches into his body, Forssmann untied the fuming Ditzen. Both then ran to the hospital’s basement x-ray department and injected x-ray dye into the catheter, yielding an image of the right side of his heart, the first made in a living human.

Thus, the very first catheterization of the heart was performed.

An x-ray image was made to document the accomplishment. Upon hearing of the experiment, Forssmann was promptly fired by superiors for his brazen act of self-experimentation. Deflated, Forssmann abandoned his experimentation and went on to practice urology. He became a member of the Nazi party in World War II Germany and served in the German army. Though condemned as crazy by some, physicians in Europe and the U.S., after hearing of his experience, furthered the effort and continued to explore the potential of the technique. Forssmann himself was never invited to speak of his experiences outside of Germany, as he had been labeled a Nazi.

Many years after his furtive experiments, the once intrepid Dr. Forssmann was living a quiet life practicing small town medicine. He received an unexpected phone call informing him that he was one of three physicians chosen to receive the 1956 Nobel Prize for Medicine for his pioneering work performing the world’s first heart catheterization, along with Drs. André Cournand and Dickinson W. Richards, both of whom had furthered Forssmann’s early work. Forssmann remarked to a reporter that he felt like a village pastor who was made a cardinal.

Strange, but true.

Rerun: To let low-carb right, you must check POSTPRANDIAL blood sugars

2. April 2010 William Davis (12)

Checking postprandial (after-eating) blood sugars yields extraordinary advantage in creating better diets for many people.

This idea has proven so powerful that I am running a previous Heart Scan Blog post on this practice to bring any newcomers up-to-date on this powerful way to improve diet, lose weight, reduce small LDL, reduce triglycerides, and reduce blood pressure.

To get low-carb right, you need to check blood sugars

Reducing your carbohydrate exposure, particularly to wheat, cornstarch, and sucrose (table sugar), helps with weight loss; reduction of triglycerides, small LDL, and c-reactive protein; increases HDL; reduces blood pressure. There should be no remaining doubt on these effects.

However, I am going to propose that you cannot truly get your low-carb diet right without checking blood sugars. Let me explain.

Carbohydrates are the dominant driver of blood sugar (glucose) after eating. But it's clear that we also obtain some wonderfully healthy nutrients from carbohydrate sources: Think anthocyanins from blueberries and pomegranates, vitamin C from citrus, and soluble fiber from beans. There are many good things in carbohydrate foods.

How do we weigh the need to reduce carbohydrates with their benefits?

Blood sugar after eating ("postprandial") is the best index of carbohydrate metabolism we have (not fasting blood sugar). It also provides an indirect gauge of small LDL. Checking your blood sugar (glucose) has become an easy and relatively inexpensive tool that just about anybody can incorporate into health habits. More often than not, it can also provide you with some unexpected insights about your response to diet.

If you’re not a diabetic, why bother checking blood sugar? New studies have documented the increased likelihood of cardiovascular events with increased postprandial blood sugars well below the ranges regarded as diabetic. A blood sugar level of 140 mg/dl after a meal carries 30-60% increased (relative) risk for heart attack and other events. The increase in risk begins at even lower levels, perhaps 110 mg/dl or lower after-eating.

We use a one-hour after eating blood sugar to gauge the effects of a meal. If, for instance, your dinner of baked chicken, asparagus brushed with olive oil, sauteed mushrooms, mashed potatoes, and a piece of Italian bread yields a one-hour blood sugar of 155 mg/dl, you know that something is wrong. (This is far more common than most people think.)

Doing this myself, I have been shocked at the times I've had an unexpectedly high blood sugar from seemingly "safe' foods, or when a store- or restaurant-bought meal had some concealed source of sugar or carbohydrate. (I recently had a restaurant meal of a turkey burger with cheese, mixed salad with balsamic vinegar dressing, along with a few bites of my wife's veggie omelet. Blood sugar one hour later: 127 mg/dl. I believe sugar added to the salad dressing was the culprit.)

You can now purchase your own blood glucose monitor at stores like Walmart and Walgreens for $10-20. You will also need to purchase the fingerstick lancets and test strips; the test strips are the most costly part of the picture, usually running $0.50 to $1.00 per test strip. But since people without diabetes check their blood sugar only occasionally, the cost of the test strips is, over time, modest. I've had several devices over the years, but my current favorite for ease-of-use is the LifeScan OneTouch UltraMini that cost me $18.99 at Walgreens.

Checking after-meal blood sugars is, in my view, a powerful means of managing diet when reducing carbohydrate exposure is your goal. It provides immediate feedback on the carbohydrate aspect of your diet, allowing you to adjust and tweak carbohydrate intake to your individual metabolism.

LDL glycation

1. April 2010 William Davis (11)

The proteins of the body are subject to the process of glycation, modification of protein structures by glucose (blood sugar). In the last Heart Scan Blog post, I discussed how glycated hemoglobin, available as a common test called HbA1c, can serve as a reflection of protein glycation (though it does not indicate actual Advanced Glycation End-products, or AGEs, just a surrogate indicator).

There is one very important protein that is subject to glycation: Apoprotein B.

Apoprotein B, or Apo B, is the principal protein of VLDL and LDL particles. Because there is one Apo B molecule per VLDL or LDL particle, Apo B can serve as a virtual VLDL/LDL particle count. The higher the Apo B, the greater the number of VLDL and LDL particles.

Because Apo B is a protein, it too is subject to the process of glycation. The interesting thing about the glycation of Apo B is that its "glycatability" depends on LDL particle size: The smaller the LDL particle, the more glycation-prone the Apo B contained within.

Younis et al have documented an extraordinary variation in glycatability between large and small LDL, with small LDL showing an 8-fold increased potential.

Think about it: Carbohydrates in the diet, such as wheat products and sugars, trigger formation of small LDL particles. Small LDL particles are then more glycation-prone by up to a factor of 8. Interestingly, HbA1c is tightly correlated with glycation of Apo B. Diabetics with high HbA1c, in particular, have the greatest quantity of glycated Apo B. They are also the group most likely to develop coronary atherosclerosis, as well as other consequences of excessive AGEs.

No matter how you spin it, the story of carbohydrates is getting uglier and uglier. Carbohydrates, such as those in your whole grain bagel, drive small LDL up, while making them prone to a glycating process that makes them more likely to contribute to formation of coronary atherosclerotic plaque.

High HbA1c: You're getting older . . . faster

28. March 2010 William Davis (16)

Over the years, we all accumulate Advanced Glycation End-products, or AGEs.

AGEs are part of aging; they are part of human disease. AGEs are the result of modification of proteins by glucose. AGEs form the basis for many disease conditions.

Accumulated AGEs have been associated with aging, dementia, cataracts, osteoporosis, deafness, cancer, and atherosclerosis. Most of the complications of diabetes have been attributable to AGEs.

There's one readily available method to assess your recent AGE status: HbA1c.

Hemoglobin is the oxygen-carrying protein of red blood cells. Like other proteins, hemoglobin becomes glycated in the presence of glucose. Hemoglobin glycation increases linearly with glucose: The higher the serum or tissue glucose level, the more glycation of hemoglobin develops. Glycated hemoglobin is available as the common test, HbA1c.

Ideal HbA1c is 4.5% or less, i.e., 4.5% of hemoglobin molecules are glycated. Diabetics typically have HbA1c 7.0% or greater, not uncommonly greater than 10%.

In other words, repetitive and sustained high blood glucose leads to greater hemoglobin glycation, higher HbA1c, and indicates greater glycation of proteins in nerve cells, the lens of your eye, proteins lining arteries, and apoprotein B in LDL cholesterol particles.

If AGEs accumulate as a sign of aging, and high blood sugars lead to greater degrees of glycation, it only follows that higher HbA1c marks a tendency for accelerated aging and disease.

Indeed, that is what plays out in real life. People with diabetes, for instance, have kidney failure, heart disease, stroke, cataracts, etc. at a much higher rate than people without diabetes. People with pre-diabetes likewise.

The higher your HbA1c, the greater the degree of glycation of other proteins beyond hemoglobin, the faster you are aging and subject to all the phenomena that accompany aging. So that blood glucose of 175 mg/dl you experience after oatmeal is not a good idea.

The lesson: Keep HbA1c really low. First, slash carbohydrates, the only foods that substantially increase blood glucose. Second, maintain ideal weight, since normal insulin responsiveness requires normal body weight. Third, stay physically active, since exercise and physical activity exerts a powerful glucose-reducing effect. Fourth, consider use of glucose-reducing supplements, an issue for another day.

While HbA1c cannot indicate cumulative AGE status, it can reflect your recent (preceding 60 to 90 days) exposure to this age-accelerating thing called glucose.

If your doctor refuses to accommodate your request for a HbA1c test, you can perform your own fingerstick test.

Slash carbs . . . What happens?

26. March 2010 William Davis (20)

Cut the carbohydrates in your diet and what sorts of results can you expect?

Carbohydrate reduction results in:

Reduced small LDL--This effect is profound. Carbohydrates increase small LDL; reduction of carbohydrates reduce small LDL. People are often confused by this because the effect will not be evident in the crude, calculated (Friedewald) LDL that your doctor provides.

Increased HDL--The HDL-increasing effect of carbohydrate reduction may require 1-2 years. In fact, in the first 2 months, HDL will drop, only to be followed by a slow, gradual increase. This is the reason why, in a number of low-carb diet studies, HDL was shown to be reduced.--Had the timeline been longer, HDL would show a significant increase.

Decreased triglycerides--Like reduction of small LDL, the effect is substantial. Triglyceride reductions of several hundred milligrams are not at all uncommon. In people with familial hypertriglyceridemia with triglyceride levels in the thousands of milligrams per deciliter, triglyceride levels will plummet with carbohydrate restriction. (Ironically, conventional treatment for familial hypertriglyceridemia is fat restriction, a practice that can reduce triglycerides modestly in these people, but not anywhere near as effectively as carbohydrate restriction.) Triglyceride reduction is crucial, because triglycerides are required by the process to make small LDL--less triglycerides, less small LDL.

Decreased inflammation--This will be reflected in the crude surface marker, c-reactive protein--Yes, the test that the drug industry has tried to convince you to take statins drugs to reduce. In my view, it is an absurd notion that you need to take a drug like Crestor to reduce risk associated with increased CRP. If you want to reduce CRP to the floor, eliminate wheat and other junk carbohydrates. (You should also add vitamin D, another potent CRP-reducing strategy.)

Reduced blood pressure--Like HDL, blood pressure will respond over an extended period of months to years, not days or weeks. The blood pressure reduction will be proportion to the amount of reduction in your "wheat belly."

Reduced blood sugar--Whether you watch fasting blood sugar, postprandial (after-meal) blood sugars, or HbA1c, you will witness dramatic reductions by eliminating or reducing the foods that generate the high blood sugar responses in the first place. Diabetics, in particular, will see the biggest reductions, despite the fact that the American Diabetes Association persists in advising diabetics to eat all the carbohydrates they want. Reductions in postprandial (after-eating) blood sugars, in particular, will reduce the process of LDL glycation, the modification of LDL particles by glucose that makes them more plaque-causing.

You may notice that the above list corresponds to the list of common plagues targeted by the pharmaceutical industry: blood pressure, diabetes (diabetes being the growth industry of the 21st century), high cholesterol. In other words, high-carbohydrate, low-fat foods from the food industry create the list of problems; the pharmaceutical industry steps in to treat the consequences.

In the Track Your Plaque approach, we focus specifically on elimination of wheat, cornstarch, and sugars, the most offensive among the carbohydrates. The need to avoid other carbohydrates, e.g., barley, oats, quinoa, spelt, etc., depends on individual carbohydrate sensitivty, though I tend to suggest minimal exposure.

Normal fasting glucose with high HbA1c

23. March 2010 William Davis (24)

Jonathan's fasting glucose: 85 mg/dl

His HbA1c: 6.7%

Jonathan's high HbA1c reflects blood glucose fluctuations over the preceding 60-90 days and can be used to calculate an estimated average glucose (eAG) with the following equation:

eAG = 28.7 X A1c – 46.7

(For glucose in mmol/L, the equation is eAG = 1.59 × A1C - 2.59)

Jonathan's HbA1c therefore equates to an eAG of 145.59 mg/dl--yet his fasting glucose value is 85 mg/dl.

This is a common situation: Normal fasting glucose, high HbA1c. It comes from high postprandial glucose values, high values after meals.

It suggests that, despite having normal glucose while fasting, Jonathan experiences high postprandial glucose values after many or most of his meals. After a breakfast of oatmeal, for instance, he likely has a blood glucose of 150 mg/dl or greater. After breakfast cereal, blood glucose likely exceeds 180 mg/dl. With two slices of whole wheat bread, glucose likewise likely runs 150-180 mg/dl.

The best measure of all is a postprandial glucose one hour after the completion of a meal, a measure you can easily obtain yourself with a home glucose meter. Second best: fasting glucose with HbA1c.

Gain control over this phenomenon and you 1) reduce fasting blood sugar, 2) reduce expression of small LDL particles, and 3) lose weight.

Can you handle fat?

21. March 2010 William Davis (19)

No question: Low-carbohydrate diets generate improved postprandial lipoprotein responses.

Here's a graph from one of Jeff Volek's great studies:

Participants followed a low-carb diet of less than 50 g per day carbohydrate ("ketogenic") with 61% fat. The curves were generated by administering a 123 g fat challenge with triglyceride levels assessed postprandially. The solid line represents the postprandial response at the start; dotted line after the 6-week low-carb effort.

Note that:

1) The postprandial triglyceride (area-under-the-curve) response was reduced by 29% in the low-carb diet. That's a good thing.

2) The large fat challenge generated high triglycerides of greater than 160 mg/dl even in the low-carb group. That's a bad thing.

In other words, low-carb improves postprandial responses substantially--but postprandial phenomena still occur. Postprandial triglycerides of 88 mg/dl or greater are associated with greater heart attack risk because they signify the presence of greater quantities of atherogenic (plaque-causing) postprandial lipoproteins.

A full discussion of these phenomena can be found in the Track Your Plaque Special Report, Postprandial Responses: The Storm After the Quiet!, part of a 3-part series on postprandial phenomena.

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

5. September 2006 William Davis (0)

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

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

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

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

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

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

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

Hospitals: Then and Now

2. September 2006 William Davis (0)

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

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

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

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

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

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

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

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

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

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

The dreaded small LDL particle

1. September 2006 William Davis (0)

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

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

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

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

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

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

Winning Through Intimidation

31. August 2006 William Davis (0)

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

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

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

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

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

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

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

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

30. August 2006 William Davis (0)

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

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

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

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

He goes on to say that

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

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

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

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

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

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

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

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

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

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

Can procedures alone keep you alive?

29. August 2006 William Davis (0)

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

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

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

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

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

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

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

Bloodletting, another antiquated health practice

Support your local hospital: HAVE A HEART ATTACK!

25. August 2006 William Davis (0)

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

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

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

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

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

Hospitals contain experts in ILLNESS

25. August 2006 William Davis (0)

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

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

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

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

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

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

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

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

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

Are there still unexplored causes of heart disease?

23. August 2006 William Davis (0)

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

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

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

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

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

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

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

Everything causes heart attack!

22. August 2006 William Davis (1)

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

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

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

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

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

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

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