Indian buffet

24. February 2011 William Davis (56)
I took my family to a local all-you-can-eat Indian buffet. It was delicious.

I confined my food choices mostly to vegetables and soups. Within about 30 minutes, I started to get that odd buzz in my head that usually signals a high blood sugar.

When I got home, my fingerstick blood glucose: 173 mg/dl. Darn it! Must have been cornstarch or other sugars in the sauces.

I got on my supine stationary bike and pedaled for 40 minutes at a moderate pace while I played Modern Warfare on XBox. (A great way, by the way, to fit in some low- to moderate-intensity exercise while occupying your brain. My wife often has to yell at me to get off, it's so much fun.)

Blood glucose at the conclusion of exercise: 93 mg/dl-- a nice 80 mg/dl drop.

This is a useful strategy to use in a pinch when you've either been inadvertently exposed to more carbohydrate than you can tolerate, or if you'd like to blunt the adverse glucose effects of a bowl of ice cream or other carbohydrate indulgence.

Should we explore the idea of a "morning-after" pill, or actually a "meal-after" pill, a supplement pill or liquid that blunts or eliminates the blood glucose rise after a meal? I've considered such an idea, but have been fearful that people would start to use it habitually. Thoughts?

American Heart Association diet makes a monkey out of you

21. February 2011 William Davis (38)
Heart Scan Blog reader, Roger, brought this New York Times article to my attention.

In an effort to develop a better experimental model for obesity than mice, scientists have turned to monkeys and other primates. The emerging observations are eerily reminiscent of what you and I witness just by going to the local grocery store or fast food outlet:

"'It wasn’t until we added those carbs that we got all those other changes, including those changes in body fat,' said Anthony G. Comuzzie, who helped create an obese baboon colony at the Southwest National Primate Research Center in San Antonio."

"Fat Albert, one of her monkeys who she said was at one time the world’s heaviest rhesus, at 70 pounds, ate “nothing but American Heart Association-recommended diet,” she said."

Yes, indeed: The American Heart Association diet makes monkeys fat. Extrapolate this a little higher on the evolutionary ladder and guess what?

This is one of the many reasons why, when I have a patient who is counseled by the hospital dietitian on the American Heart Association diet, I advise them to 1) ignore everything the dietitian told them, and then 2) follow the wheat-free, cornstarch-free, sugar-free, whole food diet I advocate.

Not unexpectedly, much of this primate research is not being devoted to just manipulating diet to achieve weight loss and health, but to develop new drugs to "treat" obesity.

Construct your glucose curve

19. February 2011 William Davis (24)
In a previous Heart Scan Blog post, I discussed how to make use of postprandial (after-meal) blood sugars to reduce triglycerides, reduce small LDL, increase HDL, reduce blood pressure and inflammatory measures, and accelerate weight loss.

In that post, I suggested checking blood glucose one hour after finishing a meal. However, this is a bit of an oversimplification. Let me explain.

A number of factors influence the magnitude of blood glucose rise after a meal:

--Quantity of carbohydrates
--Digestibility of carbohydrates--The amylopectin A of wheat, for example, is among the most digestible of all, increasing blood sugar higher and faster.
--Fat and protein, both of which blunt the glucose rise (though only modestly).
--Inclusion of foods that slow gastric emptying, such as vinegar and fibers.
--Body weight, age, recent exercise

Just to name a few. Even if 10 people are fed identical meals, each person will have a somewhat different blood glucose pattern.

So it can be helpful to not just assume that 60 minutes will be your peak, but to establish your individual peak. It will vary from meal-to-meal, day-to-day, but you can get a pretty good sense of blood glucose behavior by constructing your own postprandial glucose curve.

Say I have a breakfast of oatmeal: slow-cooked, stoneground oatmeal with skim milk, a few walnuts, blueberries. Blood glucose prior: 95 mg/dl. Blood glucose one-hour postprandial: 160 mg/dl.

Rather than taking a one-hour blood glucose, let's instead take it every 15 minutes after you finish eating your oatmeal:


In this instance, the glucose peak occurred at 90-minutes after eating. 90-minute postprandial checks may therefore better reflect postprandial glucose peaks for this theoretical individual.

I previously picked 60-minutes postprandial to approximate the peak. You have the option of going a step better by, at least one time, performing your own every-15-minute glucose check to establish your own curve.

Why is type 1 diabetes on the rise?

16. February 2011 William Davis (43)
Type 1 diabetes, also called "childhood" or "insulin-dependent" diabetes, is on the rise.

Type 2 diabetes, or "adult," diabetes, is also sharply escalating. But the causes for this are easy-to-identify: overconsumption of carbohydrates and resultant weight gain/obesity, inactivity, as well as genetic predisposition. A formerly rare disease is rapidly becoming the scourge of the century, expected to affect 1 in 3 adults within the next several decades.

Type 1 diabetes, on the other hand, generally occurs in young children, not uncommonly age 3 or 4. Type 1 diabetes also shares a genetic basis to some degree. But the genetic predisposition should be a constant. Obviously, lifestyle issues cannot be blamed in young children.
Then why would type 1 diabetes be on the rise?

For instance, this study by Vehik et al from the University of Colorado documents the approximate 3% per year increase in incidence in children with type 1 diabetes between 1978 and 2004:


(From Vehik 2007)

(For an excellent discussion of the increase in type 1 diabetes in the 20th century, see this review.)

This is no small matter. Just ask any parent of a child diagnosed with type 1 diabetes who, after recovering from hearing the devastating diagnosis, then has to stick her child's fingers to check glucose several times per day, mind carefully what he or she eats or doesn't eat, watch carefully for signs of life-threatening hypoglycemic episodes, not to mention worry about her child's long-term health. Type 1 diabetes is a life-changing diagnosis for both child and parents.

Various explanations have been offered to account for this disturbing trend. Some attribute it to the increase in breast feeding since 1980 (highly unlikely), exposure to some unidentified virus, or other exposures.

I'd like to offer another explanation: wheat.

Lest you accuse me of becoming obsessed with this issue, let me point out the four observations that lead me to even consider such an association:

1) Children diagnosed with celiac disease, i.e., the immune disease of wheat gluten exposure, have 10-fold greater likelihood of developing type 1 diabetes.

2) Children diagnosed with type 1 diabetes are 10-fold more likely to have abnormal levels of antibodies (e.g., transglutaminase antibodies) to wheat gluten.

3) Experimental models, such as in these mice genetically susceptible to type 1 diabetes, showed a reduction of type 1 diabetes from 64% to 15% with avoidance of wheat.

4) The increase in type 1 diabetes corresponds to the introduction of new strains of wheat that resulted from the extensive genetics research and hybridizations carried out on this plant in the 1960s. In particular, unique protein antigens (immune-provoking sequences) were introduced with the dwarf variant attributable to alterations in the "D" genome of modern Triticum aestivum.

Proving the point is tough: Would you enroll your newborn in a study of wheat-containing diet versus no wheat, then watch for 10 years to see which group develops more type 1 diabetes? It is a doable study, just a logistical nightmare. Perhaps the point will be settled as more and more people catch onto the fact that modern wheat--or this thing we are being sold called "wheat"--is a corrupt and destructive "foodstuff" and eliminate it from their lives and the lives of their young children from birth onwards. Then a comparison of wheat-consuming versus non-wheat-consuming populations could be made. But it will be many years before this crucial question is settled.

Yet again, however, the footprints in the sand seem to lead back to wheat as potentially underlying an incredible amount of human illness and suffering. Yes, the stuff our USDA puts at the bottom, widest part of the food pyramid.

Apo E4 and sterols: Lethal combination?

11. February 2011 William Davis (24)
Phytosterols, or just "sterols" to its friends and neighbors, are a group of cholesterol-like compounds that are abundant in the plant world. Lately, however, sterols have proliferated in the processed food supply, thanks to the observation that sterols reduce LDL cholesterol when ingested by humans.

This must mean that sterols are good for you.

Uh oh. Wait a minute: There is a rare disease called sitosterolemia in which there is unimpeded intestinal absorption of all sterols ingested through diet. They must have really low LDL cholesterols! Nope. They develop coronary disease--heart attacks, angina, etc.--in their late teens and 20s. In other words, if sterols gain access to your bloodstream, they are bad. Very bad.

Conventional thinking is that only a modest quantity of dietary sterols gain access to the bloodstream. But there are two potentially fatal flaws in this overly simplistic line of thinking:

1) What happens when you load up your diet with "heart healthy" sterols, such as those in "heart healthy" margarines, mayonnaise, and yogurt, effectively increasing sterol intake 10-fold?

2) What happens in people with the genetic pattern, apo E4, that is carried by 25% of the general population that permits much greater intestinal absorption of sterols?

My prediction: Despite the fact that sterols reduce LDL, they may, in certain genetically-susceptible people, such as those with apo E4, increase risk for heart disease: heart unhealthy.

Here are two studies that suggest that greater sterol absorption in people without sitosterolemia are at higher risk for heart disease:

Alterations in cholesterol absorption/synthesis markers characterize Framingham offspring study participants with CHD

Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study

Glucomania

8. February 2011 William Davis (52)
As I suggested in a previous Heart Scan Blog post, a glucose meter is your best tool to:

1) Lose weight
2) Cure diabetes
3) Reduce or eliminate small LDL particles
4) Achieve anti-aging or age-slowing effects

But it means getting hold of a glucose meter and applying it in a very different way.

Diabetics typically check fasting morning glucose and again several times during the day to assess medication effects. But you and I can measure blood glucose to assess the immediate effects of food choices--two very different approaches.

The concept is simple: Check a blood glucose just prior to a food or meal of interest, then one hour after finishing.

Let's take two hypothetical breakfasts. First, oatmeal, a so-called "low-glycemic index" food. Slow-cooked, stone ground oatmeal with skim milk, a handful of walnuts, just a few blueberries.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 175 mg/dl

I made those numbers up, but this is a fairly typical response for many adults. (This is why "low-glycemic index" is an absurd notion.) This kind of response causes 1) glycation, the adverse effects of glucose modification of proteins that leads to cataracts, kidney disease, cartilage damage and arthritis, atherosclerosis, skin wrinkles, etc., 2) high insulin response that cascades into fat deposition, especially visceral fat ("wheat belly"), and 3) glucotoxicity, i.e., direct damage to the pancreas that can, over years, lead to diabetes.

Next day, let's try a breakfast of 3-egg omelet made with green peppers, sundried tomatoes, and olive oil.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 93 mg/dl

This is a meal of virtually zero-glycemic index. This kind of response triggers none of the effects experienced following the oatmeal. Repeated over time and you fail to trigger glycation, you stop provoking insulin, and visceral fat mobilizes rather than accumulates: you lose weight, particularly around the middle.

We therefore aim to keep the one-hour blood glucose 100 mg/dl or less. If you start with a high fasting blood glucose of, say, 118 mg/dl, then we aim to keep the one-hour after-eating blood glucose no higher than the pre-meal.

It works. Plain and simple.

This makes the primary care docs crazy: "How dare you check your blood sugar! You're not diabetic." In truth, blood glucose meters are relatively simple devices to use. The test strips and lancets will cost a few bucks. (The meters themselves are either low-cost or free, just like Gillette sometimes sends you a beautiful new razor for free but expects you to buy the blades). These are direct-to-consumer products. While a prescription written by your doctor for a glucose meter and supplies helps insurance cover the costs, you can easily get these devices without a prescription. Some stores, like Target, keep their devices out on the shelves with the shampoo and bath soap.

Warning: Anyone taking diabetes drugs will have to consult with their doctors about the safety of such an approach. Because this approach can actually cure diabetes in some people, if you are taking some diabetes drugs, especially glyburide, glipidize, and glimepiride, you can experience dangerously low blood sugars, just as any non-diabetic taking these drugs would.

Diarrhea, runny noses, and rage: Poll results

6. February 2011 William Davis (19)
Here are the results of the week-long poll asking the question:

Have you experienced a wheat re-exposure syndrome?
Yes, undesirable gastrointestinal effects 223 (41%)
Yes, asthma or sinus problems 51 (9%)

Yes, joint pains and/or swelling 85 (15%)

Yes, emotional or other nervous system effects 59 (10%)
No, nothing, nada  107 (19%)

No. Wheat is sacred and you're all nuts  13 (2%)


There are several interesting observations to make from this informal poll. First, as I have observed, the most common wheat re-exposure syndrome is gastrointestinal, usually involving cramps, diarrhea, and lame explanations to your dinner partner.

Second most common: joint pains and/or swelling.

Third: asthma or sinus congestion.

The incidence of emotional or nervous system effects surprised me a bit. I didn't expect 10% of people to share this effect. This is an effect I also experience personally, along with the gastrointestinal consequences.

To be sure, this is a skewed poll, since many people likely come to this blog in the first place because of such issues. But I was nonetheless impressed with the relatively modest proportion of people who did not share such a re-exposure syndrome: only 19%.

Beyond the interesting numbers provided by readers, a good many also provided some fascinating and graphic comments. Here's a sample:

Reflux -- starts a day later and goes for up to a week. And Bloat:2-5 inches on my waistline in a day, lasting up to three. Miserable. And why, having experienced this once, have I done it often enough to verify the connection with certainty? I am working on that one.

Wheat increased hunger with even with only a small amount. Crackers in soup was enough to set it off.

Also, when I was trying to get off wheat, I noticed that 2 eggs and 2 bacon and I could go 5 hours before hunger, or 2 eggs and 2 bacon and toast was good for three hours before hunger. That was the final step to giving up wheat. Now three years and 59 Kg [130 lbs!] loss later, there is no doubt in my mind that wheat is evil, and I do not regard it as suitable for human food. I speculate that it increases ghrelin or cortisol.

For me, in the two years since I began eating Gluten-Free (Low Carb for 6 years), the few times I've had re-exposure to wheat, I've experienced fast onset and intense abdominal pain (known exposure during the daytime) and heartburn, indigestion, intense nausea, and disrupted sleep (exposures during evening meal not discovered until the next day).

My husband wants to think he's fine with wheat (though I know that he has at least one gene that predisposes to celiac), but IMO, he isn't. He eats no wheat at home because that's the default, and he's OK with that. But if he goes out to dinner at a restaurant that serves "good" artisan bread, he will indulge in a few bites (he does restrict his carb intake, so it's still a limited amount). More often than not, he will sleep fitfully on those nights, snore more, and wake in the night with indigestion. He wants to bury his head in the sand and will only acknowledge the discomfort being due to eating too many carbs, not the wheat itself. I notice he sleeps fine if he eats a small amount of potato or rice. Go figure.

Our 12 yo son has been eating GF for two years also. About 6 months into GF, he unknowingly ate wheat a number of times (licorice candy laces at a friend's house), which resulted in outbreaks of canker sores in his mouth each time. He also exhibits mood and behavior changes when he eats wheat, which is what prompted me to test him for gluten intolerance in the first place.

Mark said:
If I go for 3-4 days without wheat, grains or sugar and then go out and binge on a pizza and ice cream or something like that I become explosive within 20 minutes to an hour. It's like a wheat and sugar rage.(I'm not saying this is an excuse for rage, I'm saying it has happened to me and I believe partly do to re-exposure) It seems the combination of the wheat plus sugar can be the worst.

I get red rashes around my neck sometimes right away and sometimes up to a day or later and sometimes get bad diarrhea. 
I think it can be almost dangerous to cut things like gluten and sugar suddenly out of the diet without being very serious about keeping them out. I have found it very hard to cut out wheat without binging on it later after 4 or 5 days. I don't believe that my symptoms are just psychological either.
I was also diagnosed with ADHD as a young kid and then rediagnosed with adult ADHD by 3 different doctors. I also have bouts of mania at times too. I am considering trying to go completely gluten/refined carbohydrate free to see if it helps with the symptoms and gives me some relief.

I have never been tested for celiac or gluten intolerance but I would like to be. I think it would help explain to my girlfriend, family and friends why I can't go out and eat pizza or have a beer or ice cream. Right now they all think I'm a hypochondriac. At times I have experienced an intense fatigue the next day like I can't wake up and also sharp pains in my body and headaches.

I ditched wheat a year ago after my wife was diagnosed celiac. I immediately experienced a number of health improvements (blood lipids, sleep, allergies, etc.).

Fast forward: We all suffered some inadvertent wheat exposure yesterday via some chocolate covered Brazil nuts (of all things). This accidental A-B-A experimental design resulted in the following:

1. My celiac wife experienced what she calls "the flip" within an hour of exposure (i.e., intense GI distress).
2. My five-year old son went to bed with some wicked reflux.
3. I woke up with some twinges in my lower back and an ache in my football-weary left shoulder. I was also complaining to my wife about fuzzy-headedness that refused to respond to caffeine or hydration. I could only describe it as "carb flu"...

And then I read your post!

Anne said:
Depression, agitation and brain fog if I get glutened. Some times this comes with abdominal pain and a rash on my back - I think it is dose dependent. Cross contamination with wheat is a big issue when eating out. Needless to say, I eat out infrequently and then try to stick with the restaurants that are the most aware of gluten issues.
Terrence said:
Several weeks ago, I started Robb Wolf's 30 day challenge.

The first two weeks were brutal - calling it a withdrawal flu was a massive understatement. So, I thought I would try some wheat and see what happened (could not be worse, I thought). Well, it was.

I still felt extremely crappy, but I was now MASSIVELY GASSY - AMAZINGLY GASSY, for about 48 hours - flatulence on wheels, in spades. I did not go out at all in those 48 hours - when the gas came on, it went out, LONG, and QUICKLY and LOUDLY.

I am easing back into wheat and grain free. I am gluten free today and tomorrow (Sunday and Monday). I expect to try a small amount of wheat on Thursday, then maybe a little more the following Thursday.

Donald said:
I have limited wheat consumption severely over the last 8 months. I have lost 120 pounds, no longer have bouts of illness, asthma, depression, or low energy. I also take vitamin D and other supplements that have helped (many are from your blog recommendations).

Last week I ate a small piece of cake and dessert pizza. Shortly thereafter I started sneezing, had a scratchy throat, and runny nose. I called off sick the next day for fear of being contagious. My symptoms subsided quickly and I am now attributing them to the processed flour eaten at my work luncheon. I think it was an allergic reaction since I recall having much more severe symptoms fairly regularly in my wheat eating days. Those were attributed to an "allergy" of unknown origin back then.

John said:
I suffered from Ankylosing Spondylitis, Iritis, Plantar Fasciits, etc for a number of years. I restricted carbs, especially wheat and I've been symptom free for the past two years now.
Lori said:
I found wheat to be one of the worst things for giving me gas bloating and acid reflux, and I'd had sinus and nasal congestion my whole life. When I ate that cookie, it just re-introduced old problems. I can occasionally eat a gluten-free, grainy goody at my party place without any side effects. I also have a little sprouted rice protein powder every day.

Another odd thing about wheat: it was hard for me to stop eating it once I started. I could go through a whole box of cookies in one sitting, even though I wasn't a binge eater. But I can have a couple of gluten-free cookies and stop.

Paul said:
Except for one slip up this recently past holiday season, I've been sugar-grain-starch free since July 2008. Mental fog was the most noticable re-exposure symptom I had.

My mom has had the worst acid-reflux for 40-plus years. It had become so bad that she was on three medications just to deal with the symptoms. After much training and coaxing, I finally got across to her  how to totally get off wheat. Not at all to my surprise, after being wheat free for a few weeks, she lost weight and her acid reflux was GONE!

But she had been addicted to wheat for so long, she relapsed, and the reflux fire soon returned. Wheat must be akin to heroin with some people. Even though they know it's very bad for them, they can't help themselves.

Onschedule said:
Re-exposure often leads to diarrhea for me, or such a heavy feeling of tiredness that all I can do is lay down and pass out. A local pizzeria makes a darn good pie, but since I started practicing wheat-avoidance, I can't keep my eyes open after eating there. I can't say for sure that it's the wheat causing it, but definitely something in the crust. Diarrhea, on the other hand, is definitely triggered by the wheat for me.

My mom complained of gastric reflux for years, but never filled the prescriptions that her doctors would give her. I suggested wheat-avoidance- gastric reflux disappeared within 3 days and hasn't returned (has been 6 months now). I've already commented elsewhere on this blog about how much weight and bloating she has lost...

Steve said:
Interesting that I should sit down, turn on my computer and find your poll. Having gone several weeks, maybe months, avoiding gluten, I took my daughter and her boyfriend out to eat because my wife has been working late at the office lately. Although I was thinking I would just eat my steak and chicken, I succumbed to the temptation of eating about a dozen greasy, breaded shrimp that my daughter and her boyfriend ordered. It's 1:39am and I still do not feel sleepy. My left nostril is completely blocked, my stomach feels bloated, really, really full and I've been burping. In your poll I checked sinus problems but could have chose gastrointestinal or nervous problems just as well. 
A few weeks ago my daughter brought home a pizza and, once again, despite my knowing that I shouldn't, I ate a couple of pieces. I was sick for two days. The pain in what I think was my transverse colon was so bad I thought I might have to go to ther emergency room. Before I ate the pizza I had never gone grain-free that long before. I did this after reading Robb Wolf's book. 
I AM CONVINCED. No more wheat for me! Please, Lord, give me strength.
LV said:
What don't I experience! I typically avoid wheat (and gluten for that matter) as I'm pretty sure it makes me sick, but when I slip (or someone else slips me some) I end up with massive amounts of joint swelling and tenderness, diarhea, cramping, gas, bloating and brain fog. I'm absolutely miserable. Just that alone is enough to keep me off gluten. I have RA, so if I have repeated exposures I'll have a flare which SUCKS!

The perfect Frankengrain

4. February 2011 William Davis (25)
Pretend I'm a mad food scientist. I'd like to create a food that:

1) Wreaks gastrointestinal havoc and cause intractable diarrhea, cramps, and anemia.
2) Kills some people who consume it after a long, painful course of illness.
3) Damages the brain and nervous system such that some people wet their pants, lose balance, and lose the ability to feel their feet and legs.
4) Brings out the mania of bipolar illness.
5) Amplifies auditory hallucinations in people with paranoid schizophrenia.
6) Makes people diabetic by increasing blood sugars.
7) Worsens arthritis, such as osteoarthritis and rheumatoid arthritis.
8) Triggers addictive eating behavior.
9) Punishes you with a withdrawal process if you try to remove it from your diet.

I will develop a strain that is exceptionally hardy and tolerates diverse conditions so that it can grow in just about any climate. It should also be an exceptionally high yield crop, so that I can sell it cheaply to the masses.

Now, if my evil scheme goes as planned, I will then persuade the USDA that not only is my food harmless, but it is good for health. If they really take the bait, they might even endorse it, create a diet program around it.

Dag nabit! Such a plan has already been implemented. Another evil food scientist already beat me to the punch. The food is called wheat.

Diabetes: A study in aging

3. February 2011 William Davis (0)
Diabetics experience long-term health difficulties, including atherosclerosis/heart attacks, peripheral vascular disease, hypertension, cataracts, kidney disease, neuropathies, male erectile dysfunction, osteoarthritis, and colorectal cancer. They also die, on average, 10 years earlier than non-diabetics.

In effect, diabetics compress their lives into a shorter period of time. They experience all the "complications" of aging at a younger age. People without diabetes, of course, can develop atherosclerosis, cataracts, kidney disease, etc., but they tend to do so later in life compared to diabetics.

One index of the rate of aging (but not chronologic age itself) is hemoglobin A1c, or HbA1c, a "moving average" of glycated hemoglobin, i.e., glucose-modified hemoglobin. Blood glucose glycates hemoglobin linearly and irreversibly; measuring HbA1c thereby provides an index of the last 60 or so days average blood glucose.

To put HbA1c values into perspective:

Average HbA1c of hunter-gatherers: 4.5%
Average HbA1c for Americans: 5.6%
American Diabetes Association definition of diabetes: 6.5% or greater
American Diabetes Association definition of adequate control of diabetes: 7.0% or less

Why do diabetics age faster? There are likely several reasons. One important reason is glycation, as indexed by HbA1c. Glycated proteins in the lens of the eye causes cataracts. Glycated proteins in cartilage leads to arthritis. Glycated LDL particles (apo B) leads to atherosclerosis. Glycated nerve cells causes neuropathy. And so on.

If glycation underlies many of the phenomena of aging, then we might surmise that:

1) The less you glycate, the slower you age.
2) The more you glycate, the faster you age.

Therefore, the higher the HbA1c, the faster you are aging.

What foods increase HbA1c? Carbohydrates. That bowl of slow-cooked, stone ground oatmeal? A one-hour after-eating blood sugar of 170 mg/dl is common. Your doctor says that's okay because it's below 200 mg/dl and you don't "need" medication yet.

"I gained 30 lbs from one cracker"

23. May 2008 William Davis (19)

Let me tell you a story, a tale of a woman who gained 30 lbs by eating one cracker.

At age 50, Claire's health was a disaster. Her initial lipoprotein patterns were a mess, including HDL 36 mg/dl, triglycerides 297 mg/dl, blood sugar 122 mg/dl (pre-diabetic range), blood pressure 155/99. Small LDL comprised over 90% of all LDL particles.

At 5 feet 3 inches, she weighed 210 lbs--90 lbs over her ideal weight. Her face was flushed and red, her eyes swollen and weighted down with bags, her eyes dull. While interested in hearing about how to improve her health, I would hardly call her enthusiastic.

We talked about how removing wheat products entirely from her diet could result in weight loss--enormous weight loss--yet with reduced appetite, increased energy, less daytime sleepiness and fogginess, improved sleep quality. Removing wheat would also allow substantial correction of her lipoprotein patterns with minimal medication.

At first, she seemed confused by this advice. After all, it ran directly opposite to what she'd been told by her family doctor, not to mention the advice from TV, food ads, and food packages.

To my surprise, Claire did it. She didn't return to the office for another 5 months. But she came in, a big beaming smile on her face.

Even at 167 lbs--still overweight--Claire looked great. She glowed. She'd already dropped nearly 2 1/2 inches from her waist. She felt lighter on her feet, discovered energy she thought she'd lost 10 years earlier. Her blood results matched, with dramatic shifts in each and every pattern.

I quizzed Claire on her diet, and she had indeed made substantial changes. In addition to eliminating all foods made of wheat flour, she also eliminated foods made with cornstarch, rice flour, snacks, and other sweets. She ate her fill of vegetables, fruits, raw nuts, lean meats, and healthy oils. She was less hungry while eating less. Even her husband, skeptical at first, joined Claire after the first two months and her initial 20 lbs of weight loss. He, too, was well on his way to dropping to ideal weight.

But a dinner party invitation came. In the few that Claire and her husband had gone to over the few months, she had religiously stuck to her program, choosing cheese, pickles, olives, vegetables that she dipped, but avoided the pretzels, breads, Doritos, potato chips, and others.

This time, a tray of whole wheat crackers was laid on the buffet table, covered with some sort of sweetened cheese. She had just one. She savored the taste that she'd missed. "Maybe one more. I'll be extra good this weekend,'" she told herself.

Now Claire was hungry. The bruschetta covered with tomatoes and mozzarella looked awfully good. "It's got some good things on it, too!" she thought. She had three.

The floodgates opened. I saw Claire three months later, weighing just shy of 200 lbs. "I almost cancelled this appointment," she whispered quietly, tears at the corner of her eyes. "I don't know what happened. I just lost control. After losing all that weight and feeling so good, I blew it!"

I've seen it before: Fabulous success eliminating the foods that created the situation--the insatiable appetite, the endless cycle of hunger, brief satiety, the rolling, rumbling hunger--followed by temptation, then disaster. The weight lost comes right back.

It's experiences like Claire's that have absolutely, positively convinced me: Wheat products are addictive. It's not true for everybody, but it's true for many people, certainly most people who have weight struggles. It triggers some sort of appetite button, a signal to eat more . . . and more, and more. Keep it up long enough, and you have drops in HDL, increases in triglycerides, upward jumps in blood sugar and blood pressure, diabetes, etc. It doesn't matter if it's whole grain, 7-grain, or 12-grain. Yes, the whole grains contain more fiber and more B vitamins. But they all share one characteristic: They trigger a desire for more.

So that's the story of how one whole wheat cracker caused one woman to gain 30 lbs.

California woman claims: My children are aliens!

Wheat-free is not gluten-free

Eliminate wheat from your diet and wonderful things happen:

--Lose 15-20 lbs, sometimes in the first 1-3 months. (More or less, depending on your prior dietary habits, weight, age, etc.)
--HDL cholesterol goes up, triglycerides go down
--Blood sugar drops
--Small LDL is reduced
--C-reactive protein is reduced
--Pre-diabetics often convert to non-diabetics
--Diabetics gain far better control over blood glucose. Some even become non-diabetic (as long as they maintain the wheat-free, low-glycemic index diet and weight control).
--You feel better: Less mental fogginess, more energy, better sleep.
--Appetite shrinks dramatically.


(Many diet programs makes lots of money promising similar results. Prescription medications like the pre-diabetes drugs, Actos and Avandia, and the fibrates, Tricor and Lopid, nearly--nearly--reproduce the effects of eliminating wheat. Of course, these medications do not lead to weight loss or make you feel better. In fact, Actos and Avandia usually trigger a weight gain of 8 lbs in the first year of use.)


All of these wonderful effects develop with elimination of wheat. . . unless you confuse wheat-free with gluten-free. There's a difference.

Remove wheat from your diet, but discover the world of gluten-free products made for people with celiac disease, or gluten enteropathy, and you can regain the weight and recreate many of the phenomena associated with wheat. I've talked about this in past, but it trips up so many people that it's worth talking about again.

The concept that I am advocating is really low-glycemic index (or low glycemic load, actually). Foods that trigger a substantial rise in blood sugar, whether immediate (like whole wheat crackers) or delayed (like whole wheat pasta) are the culprits. The same effects develop with candy, cookies, fruit drinks, pizza, chips, table sugar, and other junk foods.

However, I pick on wheat specifically because it so dominates the American diet. It has grown to fill so many processed food products. It is also a food ingredient that is falsely advertised as healthy. In reality, pretzels, whole wheat crackers, whole grain bread, high-fiber cereals, etc. exert the same effect on blood sugar as candy or white table sugar. They also generate all the "downstream" phenomena listed above.

But wheat is hardly the only food that makes us fat, diabetic, and unhealthy. This is true for foods made with cornstarch (taco shells, cornbread, tortillas, chips, breakfast cereals); rice flour, puffed rice, and polished rice; and potatoes, particularly pulverized potato starch (potato chips). There are others.

These are the gluten-free products that are marketed to the gluten enteropathy (celiac disease) market. Yes, you can make muffins with cornstarch and no wheat gluten, but is it good for you?

No. It is nearly as bad as wheat. It can still skyrocket blood sugar, drop HDL, raise triglycerides, create small LDL, heighten inflammation, etc.

Ground flaxseed, oat bran, barley, quinoa, are some of the alternatives that do not create these effects. But not the majority of gluten-free products on the market.




Ingredients: Potato starch, rice flour, modified corn starch, olive oil, yeast, vegetable protein(lupine), corn syrup, sugar, salt, hydroxypropyl methylcellulose, sodium bicarbonate, ammonium bicarbonate, diacetyltataric acid esters of mono- and diglycerides of edible fats, natural flavor.

". . . only naturally gluten-free and wheat-free ingredients and adhere to the strictest quality processes, testing every batch for gluten using the ELISA assay."

Death to chelation?

19. May 2008 William Davis (5)

Does chelation work?

It's a question I get asked fairly frequently. Although I have never performed chelation, IV or oral, and therefore have no direct experience, my concerns for this purported therapy have included:

1) The concept of extracting calcium from atherosclerotic plaque by removing it first from the blood is absurd. Early chelationists believed that this was the means by which EDTA might reverse coronary atherosclerosis. However, removing calcium from blood would more likely lead to osteoporosis or calcium extraction from bone, since bone is a more ready repository for calcium. Blood calcium levels are also tightly and narrowly controlled; any significant reduction in calcium ("hypocalcemia") can be life-threatening. And, indeed, there have been deaths from hypocalcemia in people receiving chelation.

More recently, chelationists have argued that removal of heavy metals like lead and mercury are responsible for the purported benefits of chelation. And, indeed, blood levels of these heavy metals can be reduced by chelation. That alone may be a benefit. But to then make the leap to say that it also regresses atherosclerotic plaque by the same mechanism has no basis in science.

2) Practitioners associated with chelation tend to be shady. I have seen homeopathic therapies (among THE most ridiculous of concepts), "energy balance" therapies, desiccated organ extracts ("applied kinesiology"), and a variety of other fringe treatments offered by practitioners offering chelation. This doesn't necessarily mean, of course, that chelation is also fringe or suspect, but it tends to be offered by practitioners who engage in generally unscientific, unfounded practices.


The few people I've seen go through multiple courses of chelation (usually 30 or so infusions) have shown no impact on heart scan scores or any other measure of heart disease.

In response to the many questions I receive on chelation, I had been answering that, if we would simply wait for the publication of the NIH-sponsored trial of IV chelation therapy, perhaps we'd know once and for all.

However, in a lengthy criticism, four expert authors argue that the TACT trial to assess chelation study is doomed to failure for an entire list of reasons and should therefore be abandoned. The discussion is available on Medscape Cardiology. (Free sign-in required.)



Why the NIH Trial to Assess Chelation Therapy (TACT) Should Be Abandoned
We investigated the social and the scientific histories of chelation therapy beginning in the 1950s. We examined TACT protocols and consent forms, which, in response to Freedom of Information Act (FOIA) requests, the NIH provided to us with curious redactions. We examined the existing RCTs and the numerous case series cited by the TACT protocols. We examined evidence for risks, including information that is not in the standard medical literature. We examined various hypotheses that advocates have offered to explain how chelation "works."

We present our findings in 4 parts. First, we provide a brief history of the use of disodium EDTA as a treatment for CAD. Next, we describe the origin and nature of the TACT. Next, we discuss the evidence for chelation as a treatment for CAD and for atherosclerosis in general, and place it in the context of other proposed treatments that have been ineffective after an initial period of enthusiasm. Finally, we discuss the risks. For each topic, we contrast our findings with relevant statements in the TACT literature, to the extent that such statements exist.


Among the highlights:

--Since the mid-1970s, court documents and newspapers have reported at least 30 deaths associated with IV disodium EDTA, most of it administered by ACAM members.

--Early chelation investigators had chosen the disodium salt of EDTA, reasoning that if it could remove calcium from atherosclerotic plaques, it might shrink them. That notion was soon demonstrated to be invalid. It has largely been replaced by a "toxic heavy metals" antioxidant hypothesis, which is based on the potential for metal ions to produce free radical damage. Chelationists now cite "removing heavy metals" as the basis for their claim that chelation is effective for approximately 70 conditions, ranging from schizophrenia and autism to cancer. This provides them with numerous reasons to ignore any trial that finds chelation ineffective for CAD.

--Biochemical literature, either not cited or misrepresented in the TACT protocols, has demonstrated that the heavy metals hypothesis is implausible. Antithetically, it also demonstrates that the chelation mixture used in the TACT has pro-oxidant effects in vitro.

--In our opinion, TACT literature -- including 2 versions of the protocol, the consent form, information posted on the NCCAM Web site, and 2 editorials co-authored by the PI -- has misrepresented chelation, its risks, and the facts of the study. It has exaggerated the value of supportive case series, not only by ignoring evidence of bias and incompetence, but by misrepresenting citations and reporting erroneous data. It has minimized the dangers, both by understatements and by omissions of specific, published complications. It has not acknowledged the deaths mentioned above. It has repeatedly conflated disodium EDTA and a different drug, calcium-sodium EDTA.

--The TACT includes nearly 100 "chelation site" co-investigators who, in our opinion, are unsuitable to care for human subjects or to report trial data. Most espouse implausible health claims while denigrating proven methods; several have been disciplined, for substandard practices, by state medical boards; several have been involved in insurance fraud; at least 3 are convicted felons. Several were members of the ACAM or GLACM IRBs mentioned above. Few appear to have real expertise, required by TACT literature, in treating patients with CAD or in conducting clinical trials. Most continue to promote chelation while the TACT is in progress, contrary to good science, to human studies ethics, and to US Federal Code.


While the criticism itself does not prove the point one way or another, as a clinical trial should, anyone contemplating chelation therapy would be well-advised to read the document first. Another reference: EDTA chelation therapy for cardiovascular disease: a systematic review.

American Diabetes Association

18. May 2008 William Davis (6)

These are actual quotes from the American Diabetes Association website:


Myth #2 (from list of Diabetes Myths): People with diabetes can't eat sweets or chocolate.
If eaten as part of a healthy meal plan, or combined with exercise, sweets and desserts can be eaten by people with diabetes. They are no more “off limits” to people with diabetes, than they are to people without diabetes.



Myth #5: If you have diabetes, you should only eat small amounts of starchy foods, such as bread, potatoes and pasta.
Starchy foods are part of a healthy meal plan. What is important is the portion size. Whole grain breads, cereals, pasta, rice and starchy vegetables like potatoes, yams, peas and corn can be included in your meals and snacks. The key is portions. For most people with diabetes, having 3-4 servings of carbohydrate-containing foods is about right. Whole grain starchy foods are also a good source of fiber, which helps keep your gut healthy.





How can I have sweets and still keep my blood glucose on target?
The key to keeping your blood glucose on target is to substitute small portions of sweets for other carb-containing foods in your meals and snacks. Carb-containing foods include bread, tortillas, rice, crackers, cereal, fruit, juice, milk, yogurt, potatoes, corn, and peas. For many people, having about 45 to 60 grams at meals is about right. Serving sizes make a difference. To include sweets in your meal, you can cut back on the other carb foods at the same meal.

For example, you’d like to have cookies with your lunch. Your lunch is a turkey sandwich with two slices of bread. Your first step is to identify the carb foods in your meal. Bread is a carb. You decide to swap two slices of bread for two slices of low-calorie bread and have the cookies -- it’s an even trade. Your total amount of carbohydrate remains the same for the meal.



Can I eat foods with sugar in them?
For almost every person with diabetes, the answer is yes! Eating a piece of cake made with sugar will raise your blood glucose level. So will eating corn on the cob, a tomato sandwich, or lima beans. The truth is that sugar has gotten a bad reputation. People with diabetes can and do eat sugar. In your body, it becomes glucose, but so do the other foods mentioned above. With sugary foods, the rule is moderation. Eat too much, and 1) you'll send your blood glucose level up higher than you expected; 2) you'll fill up but without the nutrients that come with vegetables and grains; and 3) you'll gain weight. So, don't pass up a slice of birthday cake. Instead, eat a little less bread or potato, and replace it with the cake. Taking a brisk walk to burn some calories is also always helpful.


Or take a look at the recipes for breads, muffins, cakes, pies, cookies, and pizza.


My point? As I often say, while the "official" organizations like the American Diabetes Association, the American heart Association, and the USDA dominate the message provided to mainstream Americans, to those of us who know better, they have become irrelevant. You can see how obviously boneheaded their advice is. I'd go so far as to say that, if you want diabetes, follow the American Diabetes Association diet. If you have diabetes, and you'd like to accelerate complications like kidney disease, heart disease, and neuropathy, then follow the American Diabetes Association diet.

I'm going to bet that American Diabetes Association sponsors like Lilly, Novo Nordisk, Merck, Pfizer, Abbott ($1 million or more annual contributions) and Cadbury Schweppes (3-year, multi-million dollar support for Weight Loss Matters program) will continue to charge full-speed ahead to maintain the status quo. Cadbury Schweppes are the proud makers of Dr. Pepper, Hawaiian Punch, Snapple, Motts' Apple Juice, and Hires Root Beer--you know, the foods and drinks that you can have as long as you adjust your insulin dose or talk to your doctor about adjusting your diabetes medications. And if you gain, say, 30 or 40 lbs eating these foods. . . well, we've got a treatment for that. Merck's Januvia , for instance, can help you out for only about $200 a month!

Looking at the facts this way, and it seems like some cheap conspiracy theory: They're all out to get us. Dispense information that virtually guarantees propagation of the disease, and all your friends and cronies profit. I don't know if it is or it isn't, but it sure smells like it sometimes.

A tan does not equal vitamin D

14. May 2008 William Davis (8)
The sun is getting stronger and the days are getting longer, even here in Wisconsin.

Some people are coming to the office with nice tans obtained by sunning themselves for several hours. Others have come back from winter getaways to Florida, Arizona, or the tropics, also sporting nice, dark tans.

Several people, in fact, were so confident that sunning themselves provided sufficient vitamin D that they reduced their usual dose. Some even stopped their vitamin D altogether.

But, when blood levels of 25(OH) vitamin D were checked, they were virtually all low, sometimes as low as <20 ng/ml. Yet all had nice tans.

Why does this happen? Why would people with dark tans remain deficient in vitamin D?

One big factor is age: Anyone over 40 years old is fooling themselves if they think that a tan ensures raising vitamin D levels to a desirable range. Also, the more you tan, the more melanin skin pigment accumulates, and the more vitamin D activation in the skin is blocked.

Weight is another factor: Heavier people need more vitamin D, sometimes three- or four-fold more than slender people.

Why does aging result in inefficient skin activation of vitamin D? It seems that, once we are beyond our reproductively useful years, this ticking clock of aging gets triggered. The older we get, the less activation of vitamin D occurs in our skin, the less of the youth-maintaining, disease-preventing benefits of vitamin D we obtain with sun exposure.

The message: Don't rely on a tan to gauge the adequacy of vitamin D. Maybe that works when you're 16 years old, but not at age 50 or 60. There's only one way to know your vitamin D status: a blood level of 25(OH) vitamin D.

Planned obsolence

12. May 2008 William Davis (1)
In the 1960s, you’d purchase a new car. If you changed the oil, adhered to the maintenance schedule—and were lucky—you might expect to get 100,000 miles out of your automobile. Only an occasional car made it beyond that odometer hurdle. Even if the engine made it past the 100,000 mile milestone, the automobile body would inevitably start to develop rusting decay at the edges of the fenders, signaling body rot that threatened to open gaping holes of metal.



Then along came Toyota and Honda, whose cars easily reached 100,000 miles and well beyond, reliably and with bodies intact. As this realization sunk into the American consciousness, many asked, “Why can’t American automakers accomplish the same sort of trouble-free longevity?” “Buy American” emerged as a mantra to preserve American jobs and prop up an economy vulnerable to the superior automotive products from Detroit’s competitors.

Of course, American automakers have since responded to the challenge posed by the Japanese auto industry and produced automobiles that essentially matched the reliability and longevity of Japanese cars. But, the great unanswered question remains: For years before the onslaught of Japanese competition, did Detroit quietly plot to maintain a policy of planned obsolescence that ensured Americans would have to scrap the old and buy a new car every few years whenever the odometer tipped over 100,000 miles?

We will never know. At worst, it may represent the behind-closed-doors, back-slapping sort of plotting that, for many years, maximized revenues, ensured shareholder returns, and secured executive paychecks. Or, perhaps it wasn’t some evil conspiracy but just complacency, a profitable position of comfort at that. There’s little incentive for industry insiders to reveal such self-incriminating information.

But the example set by the American auto industry presents an unusual learning opportunity for us, a chance to make some useful comparisons to the heart healthcare industry.

Is the American healthcare industry also guilty of practicing a policy of “planned obsolescence,” just like Detroit? The product that helplessly crumbles is, of course, not your rust-riddled automobile, but you.

When someone sees a primary care physician year after year, yet appears one morning in the emergency room, clutching his or her chest in agony from the closed coronary artery responsible for a life-threatening heart attack—prompting the flurry of activity that results in $100,000 in hospital procedures . . .

Perhaps “planned obsolescence” is not the perfect phrase to describe the situation, but the principle still applies: A failure to inform the patient that such an outcome was possible—no, probable—makes you wonder whether such an outcome was predictable and thereby preventable in the first place.

What should we do when planned obsolescence leads us down a path engineered by someone who has something, often substantial, to gain? Even if it's just complacency, or adhering to a beaten, ineffective status quo (can you say "low-fat diet?), it all points in the same direction.

You have a choice: Refuse to buy a 1962 Impala of health care, otherwise known as conventional heart disease management.

Melatonin for high blood pressure?

10. May 2008 William Davis (15)
Melatonin is fascinating stuff.

In addition to its use as a sleep aid, melatonin exerts possible effects on cardiovascular parameters, including anti-oxidative action on LDL, reduction in sympathetic (adrenaline-driven) tone, and reduction in blood pressure.

Several studies document the blood pressure-reducing effect of melatonin:

Daily nighttime melatonin reduces blood pressure in male patients with essential hypertension.

Melatonin reduces night blood pressure in patients with nocturnal hypertension.

Prolonged melatonin administration decreases nocturnal blood pressure in women.

Blood pressure-lowering effect of melatonin in type 1 diabetes.


But blood pressure may be increased when melatonin is added to nifedipine, a calcium channel blocker:

Cardiovascular effects of melatonin in hypertensive patients well controlled by nifedipine: a 24-hour study.


Effects on BP tend to be modest, on the order of 5-8 mmHg reduction in systolic, half that in diastolic.

But don't pooh-pooh such small reductions, however, as small reductions exert mani-fold larger reductions in cardiovascular events like heart attack and stroke. NIH-sponsored NHANES data (see JNC VII), for example, document a doubling of risk for each increment of BP of 20/10. The Camelot Study demonstrated a reduction in cardiovascular events from 23% in placebo subjects to 16.7% in subjects taking amlodipine (Norvasc) with a 5 mm reduction in systolic pressure, 2 mmHg drop in diastolic pressure. Small changes, big benefits.

Many people take melatonin at bedtime and are disappointed with the effects. However, a much better way is to take melatonin several hours before bedtime, e.g., take at 7 pm to fall asleep at 10 pm. Don't think of melatonin as a sleeping pill; think of it as a sleep hormone, something that simply prepares your body for sleep by slowing heart rate, reducing body temperature, and reducing blood pressure. (You may need to modify the interval between taking melatonin and sleep, since individual responsiveness varies quite a bit.)

I also favor the sustained-release preparations, e.g., 5 mg sustained-release. Immediate-release, while it exerts a more rapid onset of sleep, allows you to wake up prematurely, The sustained-release preparations last longer and allow longer sleep.

The dose varies with age, with 1 mg effective in people younger than 40 years, higher doses of 3, 5, even 10 or 12 mg in older people. Sustained-release preparations also should be taken in slightly higher doses.

The only side-effect I've seen with melatonin is vivid, colorful dreams. Perhaps that's a plus!

The forces that shape heatlh care

8. May 2008 William Davis (5)
Thinking about the programs for health care reform proposed by the three Presidential candidates highlights a distinct peculiarity of American style health care.

American health care is shaped to an unprecedented degree by five forces:

1) The drug industry

2) The health insurance industry

3) Hospitals

4) Fear of litigation

5) The uniquely American attitude of refusing compromise in access to health care services or products, regardless of the cost (for those who can afford health insurance)


All five of these unique forces have created this thing (monster?) we call health care. Remove or modify any one of these forces, and the health care landscape would look dramatically different.

The drug industry has recently been on the receiving end of plenty of negative press. This warms my bones. Decades of heavy-handed lobbying, sleazy marketing to physicians (all too willing to be wined and dined), and behind-the-scenes manipulation of clinical data are coming back to bite them. Sadly, the drug industry is so powerful that this bit of fuss is not likely to substantially change their ways.

I am thrilled that all three Presidential candidates agree that reimportation of drugs from outside the U.S. is a good idea. While the shrug of the shoulders federal and state attitude towards importation of drugs from Canada has not resulted in cost savings sufficient to impact on overall costs, it surely will lead to savings when practiced on a broad basis by pharmacies, distributors, and other bulk buyers of pharmaceuticals.

Senator Obama, in particular, has used strong language in his criticism of the health insurance industry, tough talk that is needed in an age in which insurance executives bring home salaries in the hundreds of millions of dollars and stock prices are climbing due to substantial profit gains within the industry, going against the grain of increasingly costly premiums. However, the Clinton experiment of federalizing health care during Bill Clinton's term that caused all the big boys to band together (most notably health insurance companies and drug industry) has tempered enthusiasm for attacking the insurance industry head-on. In both Democrats' health care reform proposals, the option of private insurance is preserved, as it is in the McCain proposal.

How about hospitals? Hospitals, though on a smaller scale than the nationwide reach of the drug and insurance industries, aim to maintain health service delivery in hospitals. For instance, the high-tech bypass service in the hospital gets plenty of local media coverage, as does the newest DaVinci robotic surgery, bariatric surgery, and other revenue-rich services. Many hospitals have forgotten that their mission is delivery of health, of which revenue creation and profiting from disease should only be part.

How big is fear of litigation? Estimates vary, but several have quoted numbers in the neighborhood of 20 to 30% of overall health care costs. At the street level from what I see, I'd say at least that much. Fear of litigation is rampant, often unrestrained, and sometimes leads to the craziest, illogical sequence of testing. Chest pain, for instance, no matter how trivial, will typically trigger around $5000 worth of testing (nuclear stress test, echocardiogram, laboratory work, etc.) Emergency room visit for a minor injury? CT scan of head, chest, abdomen. A formula to minimize this aspect of fear in health care delivery would generate enormous savings.

The last issue, the uncompromising nature of Americans in health--always wanting the latest new drug, new procedure, "best" surgeon--often simply causes the health care consumer to fall victim to marketing. If a hospital advertises the newest procedure, people want it regardless of whether it represents genuine improvement over the older procedure. The newest sleeping pill, antidepressant, antihypertensive, etc. replaces the old yet equivalent product, but at considerably greater cost.

I am optimistic that, regardless of which candidate gains the White House, that some reform is on the way. I do fear, however, that progress will be small and incremental, since major change of the sort that would slash hundreds of billions of dollars in costs would rouse the powers-that-be (drug industry, health insurers, etc.) to once again combine forces and combat the disruption of their franchise.

Until you and I see real change and cost savings coming through either legislation or free market advances, we need to continue to make full use of the self-empowering health information that we gain through venues like the web.

Lipoprotein(a): Surprising Poll Results

6. May 2008 William Davis (5)
No doubt, our little informal poll asking readers whether they have lipoprotein(a), is skewed towards people inclined to respond because they have this genetic trait.

Nonetheless, the response is telling. Of 82 respondents:

--40 (48%) said they did have Lp(a)

--16 (19%) said that they did not have Lp(a)

--26 (31%) said that they did not know whether or not they had Lp(a)


Though admittedly an informal analysis, I'd draw several conclusions from this simple "experiment".

One, while the proportion of people responding that they have Lp(a) may not be accurate, it is a prevalent genetic risk factor that, according to formal studies, is present in 17% of people with coronary or vascular disease, 11% of the broader population. This number may be even higher if the newer particle number assays (measurements) are used (with results expressed in nmol/L), since an occasional person with a "normal" Lp(a) in mg/dl (weight-based) will prove to have increased Lp(a) by nmol/L (particle number-based). (The reason for this phenomenon is not clear. It may be consequent to variation in apo(a) size, with larger apo(a) varieties of Lp(a) occasionally escaping detection .) As our little poll shows, plenty of people have Lp(a).

Two, readers of this blog tend to be highly motivated, sophisticated, and knowledgeable about health and heart disease. Yet a substantial portion--31%--did not know whether they have this crucial risk factor. That shouldn't be. The unnecessary difficulty of getting this simple blood test performed has been driven home to me repeatedly when I identify this factor in someone and then suggest that their grown children and parents, each of whom have a 50% chance of having Lp(a), be tested. It's not uncommon for a 35-year old son, for instance, to say that his doctor refused, claiming it is an unproven risk marker, or to simply say that he/she doesn't know what it is.

No doubt, just knowing whether you have Lp(a) or not is not the end of the story. Reducing Lp(a) and its associated co-factors is no easy matter. With several hundred patients in my practice with Lp(a), it occupies much of my time and energy. Sometimes it leads to enormous successes , but it can also pose a real challenge.

There should no longer be any doubt that Lp(a) is associated with significantly increased risk of cardiovascular disease. This has been demonstrated conclusively across dozens of studies. Risk from Lp(a) is over and above that posed by other risk factors; it also amplifies the risk posed by other factors, e.g., small LDL, inflammatory phenemena, homocysteine, total LDL, low HDL.

In the world of Lp(a), our two most desperate needs for the future are:

1) Better education of physicians and the public, and

2) More effective treatment options.

Thus, our reasons to form The Lipoprotein(a) Research Foundation. Steps to gain tax-exempt status are being pursued as we speak.

I can't help but wonder whether, like vitamin D, a solution is right beneath our noses. An investment in research to fund the trials to better explore both basic science as well as practical treatment options might yield an answer more readily than we think. Wouldn't that be great?
