Does staying up late make you fat?

3. March 2009 William Davis (5)

Lack of sleep makes you crabby.

But can staying up late make you fat? Or diabetic? Or increase heart disease risk?

Can forcing your body to ignore its evolutionarily-programmed day-night/sleep-wakefulness cycle also distort health, even when sleep is adequate?

Yet another study adds to the growing clinical literature documenting the lack of sleep, or, in this case, the "violation" of circadian rhythms that occurs with unpredictable or shifting sleep patterns.

In this small study of 10 men and women, forcing them to sleep on an unnatural 28-hour per "day" schedule, causing a dyssynchrony with natural day-night cycles, yielded increased glucose (blood sugar) levels, poor response to insulin, increased blood pressure. It also led to a decrease in leptin levels, a phenomenon that can trigger increased appetite.

Such circadian misalignment was meant to recreate the distorted day-night cycles of shift workers, a group that is unusually prone to diabetes and heart disease. This study further confirms that there are indeed unhealthy physiologic consequences of defying normal day-night sleep cycles.

This study suggests that, not only is sufficient sleep important for health, but the predictability and concordance with normal circadian cycles is also important.

Add to this previous studies demonstrating an association with sleep deprivation and low HDL/high triglycerides (Kaneita Y, et al 2008) and increased likelihood of having a positive heart scan (coronary calcium) score (King CR et al 2008), and it is increasingly clear that sleep is a crucial factor for overall health. It may even be a helpful strategy to control weight.

A full report on the importance of sleep is planned for the Track Your Plaque website.

Vitamin D Project: Grassroots Health

3. March 2009 William Davis (24)

Here's an interesting project a Track Your Plaque Member brought to my attention: Grassroots Health.

Carole Baggerly, Director of GrassrootsHealth, is a breast cancer survivor who has engineered an impressive project to collect and tabulate vitamin D blood levels in thousands, perhaps millions of people, over the next 5 years. Anyone can participate at a cost of $30 twice a year to get a vitamin D home test kit. (A fingerprick is required. I've tried the test kit--it's easy and painless to use.) They simply ask you to provide some basic health information that will be accumulated and analyzed.

Here's a graph they feature on their website showing the vitamin D blood levels distributed among the first 300 participants:

(Click to enlarge.)

Ms. Baggerly is apparently working with vitamin D pioneer, Dr. Reinhold Vieth, of the University of Toronto.

This sounds like a really great idea. Should you enroll, please come back here and let us know about your experience.

Statin Diary

1. March 2009 William Davis (17)

Here are a sampling of some of the comments I've received from people taking statin drugs:

Barkeater said:

On Lipitor since 1997, and pretty sure I had no side effects. Hey, I am a man, I don't complain.

Work has gotten real challenging (but they pay me well). At age 52, 2 years ago, I was fed up with working hard, cranky, and wanted to quit. Very low tolerance for frustration. A year ago, I hit a low spot again, but knowing that quitting was not an option, I started pestering my wife about things married people quarrel about other than money. No matter how great she was, every month or so I would get in a complete funk about it. Meanwhile, my brother had an MI, freaking me out, so at my doctor's suggestion I doubled the Lipitor dose (to 40 mg a day), bringing LDL below 100 and total chol. to 162 (40% below what God's original design of me produced). Plus, I ached a lot after exercise with severe "arthritis" in my hip, and these pains took days to go away, and still I got mad every few weeks at my wife and otherwise into a depressed funk (one morning I wrote an essay about suicide, which was much on my mind). Mood swings could be sudden.

She finally asked whether it might be the Lipitor, which I dismissed as very unlikely because I wanted to believe I was controlling my anger and depression better at that point (not really so) and besides everyone knows that statins have very few side effects. But, I did poke around a bit, and saw that kooky internet people seemed to have a lot of statin side effects, including depression. So, I thought I would quit, as an experiment. Like the JUPITER study, the results were so stunning I had to end the experiment in just 48 hours, except unlike JUPTIER, the clear result was that statins are nasty poisins that were ruining my life. I quickly concluded that no statin would again pass my lips. Depression, gone immediately (I am now 45 days off Lipitor). Relationship with wife, great (maybe "saved" is the word). Athletic performance, vastly better (adjusted for my modest natural abilities), with aches reduced vastly. Ability to withstand frustration, zoomed way way up. I feel totally different, and better; I think of my high cholesterol as my friend, protecting my from the abyss.

The other exciting thing is that I was depending on Lipitor to prevent heart disease, but I see now that it was only a raffle in which I had one ticket, with 75 or 100 other ticket holders in the NNT raffle (to prevent a survivable coronary in the next ten years, but not to prevent death -- that is not a prize in this raffle). There are obviously way better things I can do for prevention, at low cost and no negative side effects (plenty of positive ones, though).

I feel ten years younger. I refer to quitting Lipitor as my "miracle cure." I feel a moral obligation to warn others.

It was the craziest thing, my elbows felt like they needed to pop but couldn't. I was taking 20mgs of Zocor, and the first couple of months the elbows were fine, but one day I realized they hurt and wouldn't pop. I enjoy tennis and will occasionally shoot baskets with the boys - working elbows are a requirement for both sports. I told my doctor the problem and he said to stop taking Zocor, and after two weeks he will have me try a different statin. Avoiding Zocor brought relief. After a week of being statin free the elbows stopped aching.

I havn't gone back to my doctor to receive a prescription for that new statin. After learning more about heart disease prevention from this site and others, my starting LDL was low to begin with right around 80, and so decided to take a different natural approach to lower my LDL and more importantly for me raise HDL. I cleaned up my diet and began taking nutritional supplements. It worked, today cholesterol levels are great, and I have working elbows.

Tom said:

Two weeks after I started 10mg/day of Lipitor I developed tinnitus. I had never noticed a ringing in my ears before and now all of a sudden it was LOUD. After three months I saw my doctor for a cholesterol retest (it went way down) and complained of the tinnitus. He said he hadn't heard of this side effect, but I told him the web said 2% complain of it. He suggested I go to 5mg/day to see if it helped. I tried this for a few months, then went totally off for a few weeks, and the tinnitus got better, but never went away. I'm still on a 5mg dose after 9 months and I still have tinnitus. My fear is that the damage is done and the tinnitus will never go away.

I got sun sensitivity from taking Simvastatin. Wherever my skin is exposed to the sun, it turns red and starts itching intensely and my skin looks like giant hives. I have to wear long sleeves, gloves, turtlenecks, etc.

Jegan said:

I was on Lipitor, but as a result of a recent study, asked to go on Simvastatin. I too have never suffered tinnitus until taking statins. I perceive it most at night. It sounds either like a pure high pitched white noise, or often like being stuck in an aviary with a million high pitched birds. I did not suffer any pains, but I clearly am more forgetful. I also feel depressed, and really don;t care about anything... Paying bills, family, cleaning, you name it. Also, my rosacea seems to act up a lot more.

Terri SL said:

Statin side effects are, in my personal experience, vastly under-reported. What Dr. in practice takes the time to fill out FDA complaint forms or contacts independent researchers about a pts. side effects? What pt. even knows that they can do so, whether their Dr. wants them to or not? No surprise about that 80% if you've taken statins!

I've personally taken two different statins (Pravachol, Zocor/Vytorin) and developed horrendous muscle aches even while taking CoQ-10 200 mgs. daily in divided dose. I also experienced mental fuzziness, gait instability and near complete GI shutdown, when Dr. doubled statin dosage against my protests. Stop the drug = complete reversal within ~three days!

What seems to be consistent is the dosage of the statin... the higher the dose, or the more potent the statin (Lipitor, Crestor), the greater the chance of adverse side effects. The other consistency is that Drs. out there in practice are not recommending CoQ-10 to their patients on statins, or at least that has been my experience.

Am I advocating that everyone stop their statin drug? No, I am not.

What I am advocating is that statins be used carefully, after all efforts at correction of lipid/lipoprotein patterns have been made, with an assessment of true coronary risk (not such nonsense as the Framingham score). A more reasonable application of statin drug prescription would shrink the market from its current $27 billion to a tiny fraction of that.

These drugs can be useful but are miserably and tragically overused.

How apathy saved a life

28. February 2009 William Davis (7)

John from California left this comment recently on my Wacky statin effects post. He tells such a vivid, compelling story that I had to pass it on.

I started taking statins a couple of years ago. A friend told me that he heard that they caused Alzheimers-like symptoms. I didn't think that I exhibited any effects like that, so I pretty much ignored it, except to raise the issue with my doctor.

During the last two years, I gradually lost interest in pretty much everything. It wasn't that I was forgetful, I just didn't much care about anything. Didn't care about my hobbies, quit my job, only paid bills when I felt like it, left a rental property vacant for 1 1/2 years and other similar issues.

I am normally a pretty active person with lots of pursuits. When I spoke to my doctor about my 'lack of interest and motivation', she suggested putting me on testosterone and later a mood enhancer. (I'm 60 and I lost my wife to breast cancer about 3 years ago, so I guess the thinking was either that I was going through male menopause or just depressed over her passing.)

Although I never had the muscle aches or liver problems that are considered the side effects of statins, gradually I began to feel weaker (not uncommon at 60) and more lackadaisical in my approach to bills and responsibilities. I also began suffering continual intense tinnitus and insomnia. I became crankier and more vehement in my dealings with other people and dangerously aggressive while driving.

Oddly enough, my lack of concern with paying bills led to the pharmacist telling me that Blue Shield had canceled me. Although I could easily have called the doctor for a prescription for $5 statins through KMart, I just couldn't be bothered, so I discontinued my medication.

It's been about 2 1/2 weeks since my prescription ran out. Within 4 days I began feeling better and my thinking became clearer. I no longer have tinnitus, my good mood has returned and I actually accept life's small annoyances again. Finally, I feel better physically and am more motivated. (Unfortunately, now I have to clean up all the financial garbage I've accumulated in the last year or so.)

If you take statins and begin to suffer any of the symptoms that I've noted above. Tell your doctor to take you off for a month. If your symptoms improve, you'll know why.

Although I no longer have medical insurance, one requirement of the coverage was that my cholesterol be controllable with statins. I'd rather have a heart attack or stroke and die than to go back to being the useless walking zombie that I was.

Imagine the consequences of of everyone take a statin drug, even "putting it in the water," advocated by some of my colleagues.

Make no mistake about it: The widespread, indiscriminate use of statin drugs is not without profound implications for many people. The popular notion of "the more statin agent, the better" that has propagated, thanks to the billions of dollars spent on marketing and "research," will lead to more unfortunate experiences like John.

Statins are drugs with real effects and very real side-effects.

Wheat hell

27. February 2009 William Davis (17)

Can including wheat in your diet create hell on earth?

Was The Inferno nothing more than Danté’s prediction for the state of the U.S. diet circa 2009?

I’m kidding on The Inferno allusion, but the American diet nonetheless sure does create an inferno of unhealthy phenomena.

If we define hell on earth as constant, nagging pain and discomfort; energy depleted sufficient to impair daily function; chronic bloating and diarrhea; leg swelling, peculiar rashes; progression of a multitude of diseases ranging from annoying all the way to fatal . . . well, that’s a pretty bleak picture.

I have indeed witnessed it all. Inclusion of wheat products in the human diet in many (not all--I'd estimate 70% of people) yields devastating health effects. In a few, it shortens life. In the majority, it leads to a slow, miserable hell of inflammatory diseases like arthritis, coronary disease, and cancer.

I have also witnessed dramatic reversal of these phenomena with complete removal of wheat from the diet.

(For clarity, I am not only referring to gluten sensitivity, the immune reaction gone haywire that plagues people with celiac disease. Celiac disease is indeed another variety of wheat-induced hell on earth, but there’s far more to it than that.)

Among the effects I’ve seen with wheat removal:

--Increased clarity of thought—I can vouch for this effect personally. Focus, concentration, the capacity for prolonged application of effort is restored with elimination of wheat.

--ADHD—Marked improvement in attention deficit disorder can occur in children and adults with this focus-depriving condition. Elimination of sugars and cornstarch may be necessary for full effect. While it doesn’t seem to work in everybody, the effect is powerful enough?and the implications so profound?that it is worthy of consideration in any child with this condition.

--Improved bowel health?Many people plagued by chronic bloating, diarrhea, and urgency experience complete relief. In its most extreme form, it is expressed as celiac disease. But there are a larger number of people who do not have celiac who are plagued by this lesser form of intestinal intolerance.

--Weight loss?Patients have told me that they were actually frightened when they eliminated wheat, meaning weight dropped so rapidly that they thought something was wrong. Nothing is wrong. The weight loss simply represents the removal of this bizarre, unphysiologic trigger of appetite, blood sugar, insulin, and weight gain.

Relevant to heart health, wheat elimination effects include:

--LDL cholesterol reduction?Yes, I know that it’s not what the “official” agencies say. “Reduce fat, reduce saturated fat and cholesterol will drop.” That’s barely true; reductions of saturated fat reduce LDL cholesterol, but rarely more than 20 mg/dl. In contrast, elimination of wheat yields LDL reductions of 40, 50, even 100 mg/dl. And the type of LDL reduced is the small particle variety, the kind mostly likely to lead to heart disease. (Cutting fat generally reduces large LDL, the more benign form.)

--Triglyceride reduction?Triglyceride reductions of 50, 100, even 1000 mg/dl can be achieved with elimination of wheat (though elimination of cornstarch, sugars, and other processed carbohydrates may be necessary for full benefit).

--HDL increase?A variable response, but increase of 5-10 mg/dl are common.

--Reduced inflammation?This phenomenon expresses itself in a number of ways, including dramatic reductions of the common inflammatory marker, c-reactive protein. While the media focuses on the JUPITER trial of rosuvastatin’s (Crestor) ability to reduce CRP 50-60%, wheat elimination can easily match this?without drugs.

What's more, you just feel better. Less commonly, I've seen arthritis (both common osteoarthritis and rheumatoid arthritis), skin rashes, and sleep disorders improve. I've had pre-diabetics become non-pre-diabetics, diabetics become non-diabetics.

It's not so much whether that food is carbohydrate-rich or protein-rich. It really comes down to calories, a very simple message.'
— Dr. Frank Sacks

While some advocate the notion that only calories count and diet composition makes no difference, I offer this possibility: Whether or not weight is lost by diet, there can be enormous health effects independent of weight based on the composition of diet. Inclusion or exclusion of wheat is one such crucial factor.

Unique vitamin D observations

21. February 2009 William Davis (47)

It seems not a single day passes that I don’t learn something new about this unique hormone (mis)named “vitamin D.”

From its humble beginnings recognized only as the factor responsible for bone maturation (with deficiency leading to childhood rickets), vitamin D now commands a recognized role in almost every conceivable aspect of health and disease.

Among the unique observations I’ve made over the past several years, having corrected vitamin D in well over 1000 people:

--Ankylosing spondylitis—This fairly rare genetic disease programs a peculiar solidification of the spinal column that leads to disabling restriction of spinal mobility, accompanied by incapacitating pain. A physician came to my office after reading my Life Extension summary of vitamin D’s cardiovascular benefits, After reading it, he put himself on vitamin D 10,000 units per day and verified “therapeutic” levels with a blood test. He came to my office (he requested a consultation) and proudly showed me his near-normal spine flexibility that, until approximately 2 months earlier, had left him rigid and unable to even tie his shoes. He also reported that the chronic pain that had left him completely dependent on anti-inflammatory agents and narcotics was nearly entirely gone.

--Aortic valve disease—The list of people with either aortic valve stenosis (stiffness) or insufficiency (leakiness) that develops later in life (not congenitally deformed or bicuspid aortic valves) continues to grow. Not everyone responds, but some of the cases I’ve seen have been nothing short of miraculous. One man had severe aortic valve insufficiency (severe leakiness). After one year of vitamin D, 8000 units per day that yielded a blood level of 67 ng/ml, the insufficiency was down to a minimal level. Before vitamin D, I had never witnessed “spontaneous” reversal of aortic valve disease before.

--Chest pain—Not the chest pain of heart disease, but a chronic gnawing, toothache-like pain in the sternum that is relieved within days of initiating vitamin D. I don’t know precisely why this happens, but I speculate that, with vitamin D deficiency, there is disordered calcium metabolism, and perhaps the sternal pain represents cellular (osteoclastic) activity that is eroding sternal calcium for the purpose of maintaining blood calcium, since intestinal absorption of calcium is poor. Replace vitamin D and the abnormal calcium uptake ceases. Just my guess.

--Relief from claustrophobia—This one has me stumped. But one man’s vivid description of his previously terrifying experiences in elevators and other enclosed spaces, now entirely gone raises some fascinating questions. For instance, how much psychological disease is nothing more than the expression of disordered metabolism from vitamin D deficiency?

--Immunity from viral infections--I first learned of this association from Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com). Dr. Cannell recounts his experience with the 2006 flu epidemic in the hospital in northern California, where he is a psychiatrist charged with the health of 200 inpatients held in closed wards. While the flu spread like wildfire to the patients in all the other wards, the 200 patients in Dr. Cannell’s ward failed to contract a single episode of flu while taking 2000 units of vitamin D per day.

I was a little skeptical at first, having been disappointed by the failure of several nutritional agents like zinc, vitamin C (perhaps, at best, a minimal effect). Now, three years into my vitamin D experience, I am absolutely convinced that Dr. Cannells’ early observation was correct: Vitamin D enhances immunity enormously. Not only have I personally not had a virus in several years, the majority of my staff and patients have been happily free of viral infections. There have been a few, to be sure. But the usual winters of hacking, coughing, and sneezing in the office have become largely a memory. It is a rare person who comes to the office with viral symptoms.

With new lessons being learned every day, it is inevitable that other fascinating new vitamin D observations have yet to be made.

Dr. Michael Eades on the Paleolithic diet

18. February 2009 William Davis (16)

Dr. Michael Eades has posted an absolutely spectacular commentary on the Paleolithic diet concept:

Rapid health improvements with a Paleolithic diet

The post was prompted by publication of a study that tried to recreate a Paleolithic-like diet experience over a brief study period:

Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet.

Dr. Eades discussion is wonderfully insightful and comprehensive and there's little to say to improve on his discussion.

I'd make one small point: From what I see in my experience, the improvements in lipid patterns seen in the brief period of this study are very likely to have been primarily due to the removal of wheat. Followers of this blog know that wheat elimination is among the most powerful cholesterol-reducing strategies available.

What vitamin D form?

15. February 2009 William Davis (36)

In response to questions regarding why don't vitamin D tablets work, here are my observations.

When I first started correcting vitamin D levels around 3 1/2 years ago, people would begin with starting 25-hydroxy vitamin D blood levels of around 20 ng/ml.

Taking, say, 6000 units vitamin D as tablets over 3 months yielded blood levels of 24-30 ng/ml. Taking 6000 units in an oil-based form, and blood levels would commonly be 60-70 ng/ml.

In other words, tablets are very poorly absorbed. I also saw very erratic absorption with tablets, with tremendous variation in blood levels.

I witnessed this effect many times. I finally began telling patients to avoid the tablets altogether. It's simply not worth it. Taking dose X of tablets, you cannot predict what the blood level of vitamin D will be.

Now, you can sometimes make the tablets get absorbed by either taking with a teaspoon of oil (e.g., olive, flaxseed) or taking with an oil-rich meal. However, I am uncertain just how consistent the absorption is under these circumstances, not having done this enough times to know.

Oil-filled gelcaps are no more expensive than tablets (or perhaps a dollar more). Health food store employees and pharmacists don't know this. I have had many patients come to the office claiming they changed to tablets because that's all their health food store or pharmacy carried and the person behind the counter assured them it was the same. Blood level of vitamin D to confirm: right back down to the starting level or near it--little or no absorption.

The only way to know whether a preparation is absorbed is to check a blood level. But, in my experience, having checked vitamin D blood levels thousands of times, gelcaps never fail; tablets fail over 80% of the time.

Vitamin D for the pharmaceutically challenged

14. February 2009 William Davis (20)

Most Heart Scan Blog readers already know:

Your doctor has been brainwashed by the pharmaceutical industry.

Your doctor more than likely has spent the better part of his or her career in the Guantanamo Bay of healthcare, water-boarded by seductive sales representatives, enticed with promises of fame and riches, threatened with ostracism from the clubby internal halls of healthcare if--gasp!--he or she didn't subscribe to the "rule" that only drugs are good, anything else is bad.

The same FDA-approval-is-necessary-to-be-good brand of nonsense is gaining popularity among my colleagues who, having caught some mention (on the Today Show, Oprah, or similar source of medical information), hope to join the vitamin D hoopla.

People will proudly declare that they are taking a high dose of vitamin D: 50,000 units once per week.

No. They are taking a barely useful form: D2, ergocalciferol.

Studies examining the reliability of the D2 form differ:

There's the Heaney study suggesting that D2 is less effective than D3:
Vitamin D2 is much less effective than vitamin D3 in humans

Then there's the Holick study showing they are equivalent:
Vitamin D2 is as effective as vitamin D3 in maintaining circulating concentrations of 25-hydroxyvitamin D.

My experience is more in line with the Heaney study: Little or no real effect with D2.

One particularly illustrative case I witnessed was a woman who was mistakenly prescribed D2 at 50,000 units per day. She told me that she'd been taking it for a year. I fully expected to see clear-cut signs of toxicity (e.g., high blood calcium levels). Curiously, she showed no signs of toxicity. Nor did she show any vitamin D at all in her blood: 25-hydroxy D level of zero--literally zero.

I've witnessed similar phenomena several times: plenty of vitamin D2 . . . very little vitamin D in the blood.

All in all, I suppose that D2 is better than No-D at all. But you are far better off joining the ranks of the pharmaceutically challenged and go with the stuff that really works: D3.

D3, or cholecalciferol, yields confident increases in blood levels. It is inexpensive, safe, and an exact copy of the human form of vitamin D. (Of course, gelcap or drops only, NEVER tablets.)

There is absolute NO reason to take vitamin D2, the form that sometimes works, sometimes doesn't, the facsimile plant form issued by the drug industry.

Why don't stents prevent heart attack?

12. February 2009 William Davis (11)

No study has ever documented that stents prevent future heart attack. But, in day-to-day practice, stents are frequently implanted for just this reason.

A little clarification. Stents do prevent heart attack--if the heart attack is already underway, either as an "acute myocardial infarction" or "unstable angina."

In other words, a plaque in a coronary artery can rupture just like a little volcano. Rather than spewing lava, the underlying plaque contents--fibrous tissue, inflammatory cells, cholesterol crystals, fatty material, debris--are exposed to flowing blood and trigger spasm of the artery and blood clot formation. A ruptured plaque is typically found in people who go to the emergency room with severe chest pain or have difficulty breathing.

A heart catheterization is performed, a severe (e.g., 90-100%--completely closed) is found. A stent in this situation is of clear-cut benefit.

What is not clearly beneficial is someone with no symptoms, symptoms only with physical activity that has been present for at least several months, or someone with a high heart scan score and no symptoms. In these circumstances, stent implantation does not reduce risk for future heart attack.

Why?

Take a look at this angiogram of a right coronary artery. You can seen plaque all along the artery (represented by areas that appear pinched off. There are at least 4 visible.)

Putting one 15 millimeter stent in the artery will only affect the area of artery stented. (Stents vary in length, but typically are 12-18 millimeters in length.) The right coronary artery is about 10 times or more this length. There are also two other arteries of similar length. A stent at one location will do nothing to affect the potential for rupture in any of the other plaque-laden areas.

Say a stent is implanted in the "worst" blockage in this right coronary artery, the plaque located at around 9 o'clock. What about all the other plaques? They can still rupture.

Why not put in many stents, say, 4 or 5, and stent all the visible plaques?

Two reasons: 1) Plaque you can't even see on an angiogram can still rupture, and 2) it is very costly (easily $30,000 at the very least), 3) incurs greater procedural risk, and 4) messes up the artery for future procedures, since a steel-lined artery that develops more disease in future will be more difficult to re-implant stents, bypass, or perform other procedural manipulations.

The point: Putting in stents does not reduce potential for plaque rupture in the entire artery.

What can prevent plaque rupture? That's the whole point of following an effective prevention program: prevent plaque rupture.

(Of course, this discussion cannot encompass the wide variety of potential situations that may cause your doctor to individualize your approach. Nonetheless, when advised to have an elective heart procedure, a healthy dose of skepticism and is clearly a good practice.)

Butter: Just because it's low-carb doesn't mean it's good

21. October 2010 William Davis (59)

The diet I advocate in the Track Your Plaque program to gain control over the factors that lead us to coronary plaque and heart attack is a low-carbohydrate diet. We begin with elimination of wheat, cornstarch, oats, and sugars in the context of an overall carbohydrate-reduced diet. We refine the program by monitoring postprandial (after-meal) glucoses.

But not everything low-carb is good for you. Fried sausages, for instance, are exceptionally unhealthy, despite having little to no carbohydrates.

An emerging but potentially very powerful issue is that of Advanced Glycation End-products, or AGEs. There are two general varieties of AGEs: endogenous (formed within the body) and exogenous (formed in food that is consumed).

Endogenous AGEs form in the body as a result of high blood glucose, i.e., glycation. When exposed to any blood glucose level of 100 mg/dl or greater, some measure of glycation will develop due to a reaction between glucose and various proteins, e.g., proteins in the lens of the eye, forming cataracts over time.

Exogenous AGEs form in food, generally as a result of heating to high-temperature. (AGEs is really a catch-all term; there are actually a number of reactions that occur in foods, not all of them involving sugars. However, the "AGE" label is used to signify all the various related compounds. The values quoted here are from Dr. Helen Vlassara's Mt. Sinai Hospital laboratory; reference below.)

Beef cooked to high-temperature yields plentiful AGEs. One gram of roast beef, for instance, contains 306,238 units. This means that an 8-oz serving yields 13.8 million units AGEs. Compare this to a boiled egg with 573 units per gram, raw tomato with 234 units per gram.

Butter contains an impressive 264,873 units AGEs per gram, the highest content per gram in the entire list of 250 foods tested in the Mt. Sinai study. A couple pats of butter (10 g) therefore contains 2.64 million units. A stick of butter that you might add to cake batter to make a cake therefore yields 30 million units of AGEs.

So there's nothing wrong with the fat of butter. It's AGEs that appear to be responsible for the endothelial dysfunction/artery-constricting, insulin-blocking, oxidation and inflammation reactions that are triggered. Among all of our food choices, butter is among the worst from this viewpoint.

Throw in the peculiar "insulinotrophic" effect of butter, and you have potent distortion of metabolic pathways, courtesy of the butter on your lobster.

(AGE data from Goldberg 2004. In this analysis, carboxymethyllysine was the marker used for AGE content.)

Incidentally, the new Track Your Plaque diet will soon be released as chapter 9 of the new Track Your Plaque book on the website.

Einkorn now in Whole Foods

16. October 2010 William Davis (19)

I just saw this at Whole Foods: einkorn pasta.

In my einkorn bread experience (In search of wheat: We bake einkorn bread), I was spared the high blood glucose and neurologic and gastrointestinal effects of conventional whole wheat grain (dwarf Triticum aestivum). I shared the einkorn bread with four other people with histories of acute wheat sensitivities, only one of whom experienced a mild diffuse joint reaction, the other three not experiencing any symptoms.

Anyone wishing to try einkorn can now obtain commercial pasta from Jovial, an Italy-based manufacturer. It comes in spaghetti, linguine, rigatoni, fusilli, and penne rigate shapes.

Eli Rogosa, founder of The Heritage Wheat Conservancy, tells me that, in her experience, celiac suffers seem to not experience immunologic phenomena triggered by conventional wheat.

However, we've got to be careful here. The so-called ("diploid") "A" genome of einkorn shares many of the same genes as the ("hexaploid") "ABD" genomes of modern wheat, including overlap in the sequences coding for the 50-or so different glutens and glutenins. Most of the genes that code for the glutens that cause celiac and related illnesses reside in the "D" genome that are absent in the einkorn "A" genome. However, the "A" genome still codes for glutens. So there is potential for activating celiac disease in some people. Insufficient research has been devoted to this question. It is a question of extreme importance to people with celiac and other immune-mediated conditions, since re-exposure to the wrong form of gluten can increase risk of intestinal lymphoma 77-fold, as well as risk of other gastrointestinal cancers.

So einkorn should not be viewed as a cure-all for all things wheat, but as something to consider for a carbohydrate indulgence. Yes, indeed: It is a carbohydrate, with 61 grams ("net") carbs per 4 oz (uncooked) serving.

Should anyone give it a try, please be sure to report back your experience, especially if you have a history of wheat intolerance. If you have a glucose meter, pre- and 1-hour post values are the ones to measure to gauge the blood sugar effects of consumption. Because pasta tends to cause long sustained blood sugar rises, another value at 2-4 hours might be interesting.

Noodles without the headaches

14. October 2010 William Davis (26)

If you are looking for a wheat-free noodle or pasta, shirataki noodles are worth a try.

Shirataki noodles are low-carbohydrate (less than 3 g per 8 oz package) and, of course, do not trigger all the unhealthy effects of wheat--no blood sugar/insulin provocation, no addictive brain effects (exorphins), no gluten-mediated inflammatory effects.

(I advise avoiding gluten-free pasta alternatives made with rice flour and other common gluten alternatives, since they trigger blood sugar, small LDL, and growth of visceral fat just like wheat.)

I made a stir-fry using the shirataki-tofu noodles, shown below. (Tofu is added to make the noodles more noodly in consistency, as opposed to the chewier non-tofu variety.) The noodles were a lot like the ramen I used to eat as a kid. They were filling and tasted great in the sesame oil, soy sauce, tofu, and vegetables I used.

The noodles are easy to use. Just drain liquid out of package. (The noodles come in water.) Rinse in collander 30 seconds, then boil for 3 minutes. Add to your stir-fry or other dish. Some manufacturers, such as House Foods, also have angel hair and fettucine style noodles.

You're fried

13. October 2010 William Davis (26)

If I could invent a food that illustrates nearly all of the shortcomings of the American diet, it would be French fries, the familiar fixture of fast food.

What we have come to view as French fries contain just about every one of the unhealthy ingredients that lead us down the path of obesity, diabetes, heart disease, high blood pressure, etc.

Let's take them one by one:

Potato starch--Potato starch exerts an effect on blood sugar similar to that of table sugar, only worse. (Glycemic index french fries 75; glycemic index sucrose 65.)

Advanced Glycation End-products (AGEs)--AGEs form when proteins and fats are subjected to high temperature cooking; the longer the high temperature, the more the food reaction creating AGEs proceeds. AGEs are the likely culprit in roasted and fried foods that made it appear that saturated fats were bad, when it was really AGEs all along. AGEs have been shown to block insulin's effects, increase blood sugar, cause endothelial dysfunction and high blood pressure.

Acrylamides--Acrylamides, like AGEs, are created through high-temperature heating. French fries are unusually rich in AGEs. Brewed coffee also contains a small quantity, while French fries contain 82-fold greater quantities, among the highest of all known sources of acrylamides.

Oxidized oils--The amount of oxidized oils will depend on what sort of oil was used for frying. As more restaurants are trying to get away from hydrogenated oils, many are turning back to polyunsaturates. Others are turning to commercial-grade oils that contain both hydrogenated and polyunsaturates. If oils are permitted to oxidize, then they will trigger oxidative phenomena in your body upon consumptions, e.g., LDL oxidation (Staprans 1994).

In other words, the innocent appearing French fry unavoidably triggers oxidation, all the phenomena triggered by high blood glucose (high insulin, glycation, visceral fat accumulation), along with the cascade of effects arising from AGEs and acrylamides.

Top your French fries with some ketchup made with high-fructose corn syrup that exagerrates AGE formation, visceral fat, and distorts postprandial (after-eating) effects.

Is it any wonder that we've lost control over diet?

Bosom buddies

9. October 2010 William Davis (22)

Male breast reduction surgery is a booming business. While most industries are in a downward tailspin, breast reduction surgery in men is growing at double-digit rates.

Other efforts, some legitimate, some not, are also cropping up, all intended to help men deal with this embarassing problem:

Exercise programs to reduce male breast size.

Liposuction--Not just for the belly!

Plastic surgery

Gynexin--a supplement that purportedly reduces male breast size.

Conventional medical treatment also includes estrogen blocking drugs, the same ones used to treat breast cancer, drugs like tamoxifen. There's even clothing intended to make breasts less obvious.

While male breast enlargement--"gynecomastia"--can occasionally occur due to rare endocrinologic problems, such as high prolactin hormone levels (hyperprolactinemia) or somewhat more commonly as failed testosterone production (hypogonadism), the vast majority of men who suffer with this problem simply have high estrogen levels.

Makes sense: Women develop larger breasts during development mostly due to increased levels of estrogen. A parallel situation in men likewise stimulates breast tissue.

So where does the excess estrogen come from?

Visceral fat converts testosterone to estrogen. Men with excess visceral fat therefore develop low levels of testosterone and high levels of estrogen. Estrogen levels can, in fact, be substantially higher compared to slender males.

So what foods cause the accumulation of visceral fat and, thereby, increased estrogen and decreased testosterone?

Foods that increase blood glucose and insulin to the greatest degree are the foods that begin this cascade. The common foods that increase blood sugar the most? Here's a list, starting with most blood glucose-insulin provoke at the top, least at the bottom:

Gluten-free foods (dried, pulverized cornstarch, rice starch, potato starch, tapioca starch)
Whole wheat bread
Sucrose
Milky Way bars
Snickers bars

So the whole wheat sandwiches you've been eating increase blood sugar and insulin, leading to visceral fat. (And, yes, whole wheat bread increases blood sugar higher than Milky Way bars and Snickers bars.) The more visceral fat grows, the more resistant to the effects of insulin you become, further escalating blood sugar. Estrogen increases, testosterone drops, mammary gland tissue grows, normal male breasts grow to B- or C-cup size.

Yet again, an entire industry is growing from the unintended consequence of conventional advice. In this instance, the advice to "eat more healthy whole grains" leads to this booming industry of male breast reduction efforts from surgery to medications to clothing. The REAL solution: Eliminate the foods that start the process in the first place.

Don't be a dipstick

3. October 2010 William Davis (32)

If I want to know how much oil is in my car's engine, I check the dipstick.

The dipstick provides a gauge of the amount of oil in my engine. If the dipstick registers "full" because there an oil mark at one inch, I understand that there's more than one inch of oil in my engine. The dipstick provides an indirect gauge of the amount of oil in my engine.

That's what cholesterol was meant to provide: A gauge, a "dipstick," for the kind of lipoproteins (lipid-carrying proteins) in the bloodstream.

Lipoproteins are a collection of particles that are larger than a single cholesterol molecule but much smaller than a red blood cell. Lipoproteins consist of many components: various proteins, phospholipids, lots of triglycerides, as well as cholesterol. In the 1960s, methods to characterize lipoproteins were not widely available, so the cholesterol in lipoproteins were used as a "dipstick" to assess low-density lipoproteins ("LDL cholesterol") and high-density lipoproteins ("HDL cholesterol"). (Actually, even "LDL cholesterol" was not measured, but was derived from "total cholesterol," the quantity of cholesterol in all lipoprotein fractions.)

Some other component of lipoproteins could have been measured instead of cholesterol, such as apoprotein B, apoprotein C, or others, all meant to act as the "dipstick" for various lipoproteins.

Relying on cholesterol to characterize lipoproteins provides a misleading picture. Imagine watching cars go by at high speed while standing on the side of the highway. You want to count how many people--not cars, but people--go by in a given amount of time. Because you cannot make out the detail of each and every car whizzing by, you count the number of cars and assume that each car carries two people. Whether it's rush hour, Sunday morning, late evening, rainy, sunny, or snowing, you make the same assumption: two people per car.

That's what cholesterol does: It is assuming that each and every lipoprotein particle (car) carries the same amount of cholesterol (people).

But that may, obviously, not be true. A bus goes by carrying 25 people. Plenty of cars may carry just the driver. People carpooling may be in cars carrying 3 or 4 people. Assuming just 2 people per car can send your estimates way off course.

That is precisely what happens when your doctor tries to use conventional cholesterol values (total cholesterol, LDL cholesterol) to gauge the lipoproteins in your bloodstream. Measuring cholesterol can also provide the false impression that cholesterol is the cause of heart disease, even though it was originally meant to simply serve as a "dipstick."

What we need to do is to characterize lipoproteins themselves. We can distinguish them by size, number, density, charge, and the type and form of proteins contained within. It provides greater insight into the composition of lipoproteins in the blood. It provides greater insight into the causes underlying coronary atherosclerotic plaque. It can also tell us what dietary changes trigger different particle patterns and how to correct them.

Until you have a full lipoprotein analysis, you can never know for certain 1) if you will have heart disease in your future, or 2) how your heart disease was caused.

Unfortunately, the vast majority of doctors are perfectly content to just count cars going by and assume two people per car, i.e., confine assessment of your heart disease risk using cholesterol . . . just as drug industry marketing has instructed them.

It's not your job to educate your doctor. If he or she refuses to provide access to lipoprotein testing to better determine your heart disease risk, then consider going out on your own. Many of our Track Your Plaque program followers have obtained lipoprotein testing on their own through Direct Labs.

The ultimate insurance company cost savings

29. September 2010 William Davis (48)

I had a very disturbing conversation with a physician who is employed by an insurance company last week.

I admitted a patient in the hospital for very clear-cut reasons. She is one of my few non-compliant patients, doing none of the strategies I advocate--no fish oil, no vitamin D, no correction of her substantial lipoprotein abnormalities, not even medication. Much of this was because of difficult finances, some of it is because she is from the generation (she is in her late 70s) that tends to ignore preventive health, some of it is because she is a kind of happy-go-lucky personality. So her disease has been progressive and, now, life-threatening, including an abdominal aneurysm near-bursting in size (well above the 5.5 cm cutoff). The patient is also a sweet, cuddly grandmother. I have a hard time bullying nice little old ladies.

While she was in the hospital, the social worker told me that her case was being reviewed by her insurer and would likely be denied. Their medical officer wanted to speak to me.

So the medical officer called me and started asking pointed questions. "Why did you do that test? You know that she's not been compliant. Are you sure you want to do that? I don't think that's a good idea." In other words, this was not just a review of the case. This was an opportunity for the insurance company to intervene in the actual care of the patient.

Then the kicker: "Have you considered not doing anything and . . . just letting nature take its course?"

At first, I was stunned. "You mean let the patient die?"

Expressed in such blatant terms, while he was trying to be diplomatic, made him back down. "Well, uh, no, but she is a high-risk patient."

Anyway, this was the first instance I've encountered in which the insurance company is not just in the business of reviewing a case, but actually trying to intervene during the hospital stay, to the point of making the ultimate healthcare cost savings: Letting the patient die.

Unfortunately, never having had an experience like this before, I did not think to record the conversation or take notes. I am wondering if this is an issue to be taken up by the Insurance Board . . . or is this a taste of things to come as the health insurers fall under increasing pressure with the legislative changes underway?

Salvation from halogenation

24. September 2010 William Davis (26)

Iodine is a halogen.

On the periodic table of elements (remember the big chart of the elements in science class?), the ingenious table that lays out all known atomic elements, elements with similar characteristics are listed in the same column. The elegant genius of the periodic table has even allowed prediction of new, undiscovered elements that conform to the "laws" of atomic behavior.

Column 17 (also called "group VIIa") contains all the halogens, of which iodine is one member. Other halogens include fluorine, chlorine, and bromine.

Odd phenomenon in biologic systems: One halogen can often not be distinguished from another. Thus, a chlorinated compound can cleverly disguise itself as an iodinated compound, a brominated compound can mimic an iodinated compound, etc.

What this means in thyroid health is that, should sufficient iodine be lacking in the body, i.e., iodine deficiency, other halogens can gain entry into the thyroid gland.

While a polychlorinated biphenyl (PCB) molecule may be recognized as an iodinated compound, it certainly doesn't act like an iodinated compound once it's in the thyroid's cells and can disrupt thyroid function (Porterfield 1998). Another group of chlorine-containing compounds, perchlorates, that contaminate groundwater and are found as pesticide residues in produce, are extremely potent thyroid-blockers (Greer 2002). Likewise, bromine-containing compounds, such as polybrominated diphenyl ethers (PBDEs), widely used as flame retardants, also disrupt thyroid function (Zhou 2001). Perfluorooctanoic acid (PFOA), found in Teflon non-stick cookware and stain-resistant products, has been associated with thyroid dysfunction (Melzer 2010). PFOA, incidentally, can disrupt thyroid dysfunction that will not show up in the TSH test used by primary care physicians and endocrinologists to screen for thyroid dysfunction. (In fact, the presumed champions of thyroid health, the endocrinology community, have proven a miserable failure in translating and implementing the findings from toxicological science findings to that of preserving or restoring thyroid health. They have largely chosen to ignore it.)

We therefore navigate through a world teeming with halogenated thyroid blocking compounds. We should all therefore avoid such exposures as perchlorates in produce by rinsing thoroughly or purchasing organic, avoid non-stick cookware, avoid use or exposure to pesticides and herbicides.

Another crucial means to block the entry of various halogenated compounds into your vulnerable thyroid: Be sure you are getting sufficient iodine. While it doesn't make your thyroid impervious to injury, iodine circulating in the blood in sufficient quantities and residing in sufficient stores in the thyroid gland provides at least partial protection from the halogenated impostors in your life.

I make this point in the context of heart disease prevention, since even the most subtle degrees of thyroid dysfunction can easily double, triple, or quadruple heart disease risk. See related posts, Is normal TSH too high? and Thyroid perspective update.

Lipitor-ologist

22. September 2010 William Davis (30)

One of the things I do in practice is consult in complex hyperlipidemias, the collection of lipoprotein disorders that usually, but not always, lead to atherosclerosis.

First order of business: Make the diagnosis--familial combined hyperlipidemia, hypoalphalipoproteinemia, lipoprotein(a), familial heterozygous hypercholesterolemia, familial hypertriglyceridemia, hyperapoprotein B with metabolic syndrome, etc. These are the disorders that start with a genetic variant, e.g., a missing or dysfunctional enzyme or signal protein, such as lipoprotein lipase or apo C3.

I then ask: What can be done that is easy and safe and preferably related to diet and lifestyle?

By following an effective diet, many of these abnormalities can be dramatically corrected, sometimes completely. Familial hypertriglyceridemia, for instance, an inherited disorder of lipoprotein lipase in which triglyceride levels can exceed 1000 mg/dl, high enough to cause pancreatic damage, responds incredibly well to carbohydrate restriction and over-the-counter fish oil. I have a number of these people who enjoy triglyceride levels below 100 mg/dl--unheard of in conventionally treated people with this disorder.

Then why is it that, time after time, I see these people in consult, often as second or third opinions from lipidologists (presumed lipid specialists) or cardiologists, when the only solutions offered are 1) Lipitor or other statin drug, and 2) a low-fat diet? Occasionally, an aggressive lipidologist might offer niacin, a fibrate drug (Tricor or fenofibrate), or Lovaza (prescription fish oil).

Sadly, the world of lipid disorders has been reduced to prescribing a statin drug and little else, 9 times out of 10.

I don't mean to rant, but I continue to be shocked at the incredible influence the drug industry has over not just prescribing patterns, but thinking patterns. Perhaps I should say non-thinking patterns. The drugs make it too easy to feel like the doctor is doing something when, in truth, they are doing the minimum (at best) and missing an opportunity to provide true health-empowering advice that is far more likely to yield maximum control over these patterns with little to no medication.

All in all, I am grateful that there is a growing discipline of "lipidology," a specialty devoted to diagnosing and treating hyperlipidemias. Unfortunately, much of the education of the lipidologist is too heavily influenced by the pharmaceutical industry. Not surprisingly, the drug people favor "education" that highlights their high-revenue products.

Seeing a lipidologist is still better than seeing most primary care physicians or cardiologists. Just beware that you might be walking into the hands of someone who is simply the unwitting puppet of the pharmaceutical industry.

Robb Wolf's new Paleo Solution

20. September 2010 William Davis (16)

The Paleo Solution: The Original Human Diet

I have to say: I'm impressed. If you would like insight into why a "Paleo" nutritional approach works on a biochemical level--why you lose weight, burn fat, and gain overall better health--then Robb's book is worth devoting a few hours to, of not a reread or two.

Robb has a particular knack for organizing and presenting information in a way that makes it immediately accessible. You will gain an appreciation for how far American nutritional habits have veered off course.

Because Robb brings expertise from his academic biochemistry background, as well as personal trainer and educator running a successful gym in northern California, NorCal Strength and Conditioning, he delivers a book packed with information that is extremely easy to convert to immediate action in health and exercise. He seems to anticipate all the little problems and objections that people come up with along the way, dealing with them in his characteristic lighthearted way, providing practical, rational solutions.

Robb's book nicely complements what Dr. Loren Cordain has written in his The Paleo Diet: Lose Weight and Get Healthy by Eating the Food You Were Designed to Eat and The Paleo Diet for Athletes: A Nutritional Formula for Peak Athletic Performance. (My wife is now reading The Paleo Diet for Athletes and loves it. I'm going to add Robb's book to her reading list for her to read next.)

If nutrition has you stumped, if the USDA food pyramid still sounds like a reasonable path, or if you just would like to understand nutrition a little bitter, especially its biochemical ins and outs, Robb's book is a wonderful place to start.

Cholesterol effects of carbohydrates

24. March 2009 William Davis (31)

Let's take a hypothetical person, say, a 50-year old male. 5 ft 10 inches, 160 lbs, BMI 23.0. He's slender and in good health.

Our hypothetical man eats a simple diet of vegetables, some fruit, nuts, and meats but avoids processed industrial foods. By macronutrient composition, his diet is approximately 30% protein, 40-50% fat, 20-30% carbohydrate. His starting lipid panel:

Total cholesterol 149 mg/dl
LDL cholesterol 80 mg/dl
HDL 60 mg/dl
Triglycerides 45 mg/dl

His starting lipids are quite favorable (though I don't often see this kind of starting panel nowadays except in athletes). We begin here because this hypothetical man is going to serve as our test subject.

We ask our hypothetical man to load his diet up on "healthy whole grains." He complies by eating whole grain cereals for breakfast, whole wheat toast; sandwiches made with whole grain bread; dinners of whole wheat pasta; snacks of granola bars, whole wheat pretzels and crackers.

Three months later, his lipids show:

Total cholesterol 175 mg/dl
LDL cholesterol 130 mg/dl
HDL 45 mg/dl
Triglycerides 150 mg/dl

You can see that LDL cholesterol has increased, HDL has dropped, and triglycerides have increased. This wave of change is the hallmark of carbohydrate excess, but more specifically of overreliance on wheat products. Beyond his lipid panel, the man has gained 10 lbs, all concentrated in a soft roll around his abdomen, his blood sugar is now in the "borderline range" of between 110 and 126 mg/dl, i.e., pre-diabetic.

If we were to examine this man's advanced lipoproteins (e.g., NMR from Liposcience, or VAP from Atherotech), we would see that there has been an explosive increase in small LDL particles, along with a shift of large HDL to small, and the appearance of multiple abnormal classes of particles called VLDL and IDL (signalling abnormally slowed clearance of dietary by-products from the blood).

Familiar scenario? The "after-carbohydrate" situation is the rule among the people who I first meet who claim to be eating a "healthy" diet, though their patterns are usually much worse, with higher LDL, lower HDL, and much higher triglycerides, an exaggeration of our hypothetical man's abnormalities.

What if our hypothetical man now goes to his conventionally thinking (read "taught medicine by the pharmaceutical industry") physician? What will likely be the advice he receives? Reduce his saturated fat intake, eat plenty of healthy whole grains, take a statin drug.

Although my illustrative man is hypothetical, I've seen this scenario play out many thousands of times. It happens in real life all the time. It is predictable, it is highly manipulable. Sadly, it is rarely recognized for what it is: the result of excess carbohydrates, or what I call "Carbohydrate Intolerance Syndrome."

The misinterpretation of this condition has created 1) an epidemic of diabetes and pre-diabetes, 2) a nation of frustrated obese Americans, 3) a $27 billion per year statin industry, 4) another growth opportunity for the drug industry in diabetes drugs.

Wheat Belly Revisited

23. March 2009 William Davis (24)

Do you have a wheat belly?

When I first coined this phrase back in July, 2007, I had witnessed the phenomenal health effects of wheat elimination in several hundred patients.

In the nearly two years that have passed since my original post, I have witnessed hundreds more people who have done the same: eliminate pretzels, crackers, breads of all sorts, bagels, pasta, muffins, waffles, pancakes, etc.

If anything, I am convinced now more than ever that wheat is among the most destructive foods in the human diet. At least 70% of people who eliminate wheat from their diet obtain at least one, if not several, substantial health benefits.

Now, if I were trying to sell you something, say, an alternative to wheat, then you should be skeptical. If I tell you that drug or nutritional supplement X is great and you should take it, only to follow it with a sales pitch, you should be skeptical.

What am I selling? Nothing. I gain nothing by telling everyone to avoid wheat. In fact, I wish it wasn't true. Wheat foods taste good. Wheat flour makes great comfort foods. In years past, I spent many hours sitting at the bagel shop reviewing papers over a cup of coffee and a bagel. No longer.

So here, back by popular demand, the original Wheat Belly post:

Wheat Belly

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

How about "wheat belly"?

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

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

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

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

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

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

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

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

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

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

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

Thank you, Crestor

20. March 2009 William Davis (9)

I'm sure everyone by now has seen the Crestor ads run by drugmaker, AstraZeneca. TV ads, magazine ads, and the Crestor website all echoing the same message:

"While I was busy building my life, something else was busy building in my arteries: dangerous plaque."

While previous drug trials with Mevacor, Pravachol, Zocor, and Lipitor have focused mostly on examining whether the drugs reduced incidence of cardiovascular events, Crestor studies have also focused on effects on atherosclerotic plaque volume. The best example is the ASTEROID trial that demonstrated approximately 7% reduction in plaque volume by intracoronary ultrasound.

So the AstraZeneca decision makers took the leap from cholesterol reduction to plaque reduction.

I'm sure this switch wasn't taken lightly, but was the topic of discussion at many meetings before the decision to make plaque reduction the focus of hundreds of millions of dollars of advertising. After all, billions of dollars are at stake in this bloated statin market.

Ordinarily, I couldn't care less about how the drug manufacturers conduct their advertising campaigns. But this one I paid attention to because the Crestor ads are helping fuel a new way of thinking about coronary heart disease: It's not about the cholesterol; it's about the atherosclerotic plaque that accumulates in arteries.

It's not cholesterol that grows, limits coronary blood flow, and causes angina. It's not cholesterol that "ruptures" its internal contents to the surface within the interior of the blood vessel and causes blood clot and heart attack. It's not cholesterol that fragments from the carotid arteries and showers debris to the brain, causing stroke. It's all plaque.

I took the same leap years ago, though not backed by hundreds of millions of dollars of marketing money. When I first called my book Track Your Plaque, some of the feedback I got from editors included comments like "I thought this was a book about teeth!" Even now, the word "plaque" in the book title and website is responsible for confusion.

But AstraZeneca is helping me clear up the confusion. As the word plaque gains hold in public consciousness, it will become increasingly clear that cholesterol reduction is not what we're after. We are looking for reduction of plaque.

If you are trying to develop an effective means to reduce or reverse coronary heart disease, then there are two simple equations to keep in mind:

Plaque = coronary heart disease

Cholesterol ? coronary heart disease

Plaque is the disease, cholesterol is not. Cholesterol is simply a crude risk for plaque.

While I'm no friend to the drug industry nor to AstraZeneca, some good will come of their efforts.

Supermarkets and buggy whips

17. March 2009 William Davis (17)

Will supermarkets eventually phase out, joining the history books as a phenomenon of the past? Or are supermarkets here to stay, an emblem of the industrialization of our food--easy access to foods that are convenient, suit the undiscriminating masses, stripped of nutritional value despite the prominent health claim on the package front?

Anna left an insightful comment on the last Heart Scan Blog post, Sterols should be outlawed, along with some useful advice on how to avoid this trap for poor health called a supermarket:

I rarely shop in regular supermarkets anymore (farm subscription for veggies, meat bought in bulk for the freezer, eggs from a local individual, fish from a fish market, freshly roasted coffee from a local coffee place, etc.). What little else I need comes from quirky Trader Joe's (dark chocolate!), the fish market, farmer's markets, a small natural foods store, or mail order.

When I do need to go into one of the many huge supermarkets near me, not being a regular shopper there, I never know where anything is, so I have to ramble a bit around the aisles before I find what I'm looking for (and I almost always can grab a hand basket, instead of a trolley cart).

It's almost like being on another planet! There's always so many new products (most of them I hesitate to even call food). It's really a shock to the senses now to see how much stuff supermarkets sell that I wouldn't even pick up to read the label, let alone put in a cart or want to taste. I'm not even tempted by 99% of the tasting samples handed out by the sweet senior ladies in at Costco anymore (only thing I remember tasting at Costco in at least 6 mos was the Kerrygold Irish cheese, because I know their cows have pasture access and it's real food).

What's really shocking to me is how large some sections of the markets have become in recent years. While Americans got larger, so did some sections of the supermarket (hint - good idea to limit the consumption of products from those areas). Meat and seafood counters have shrunk, though. Produce areas seem to be about the same size as always (but more of it is pre-prepped and RTE in packaging.

But the chilled juice section is h-u-g-e! And no, I don't think there is a Florida orange grove behind the cases. Come on, how much juice do people need? Juice glasses used to be teeny tiny, for a good reason. To me it looks like a long wall stocked full of sugar water. Avoiding that section will put a nice dent in the grocery expenses.

The yogurt case is also e-n-o-r-m-o-u-s! Your 115 yo Bulgarian "grandmother" wouldn't know what to make of all these "pseudo-yogurts"! Chock full of every possible variety, but very little fit to eat. The only yogurts I'll look at are made with plain whole milk, without added gums, emulsifiers, or non-fat milk solids, and live cultures (I mostly buy yogurt now and then to refresh my starter culture at home). I can flavor them at home if needed. The sterols are showing up in processed yogurts, too, along with patented new strains of probiotic cultures (I'll stick to my old fashioned, but time-proven homemade lacto-cultured veggies and yogurt instead).

I found the same "cooler spread" in the butter & "spread" section. The spread options were just grotesque sounding. Actually, the butter options weren't much better, as many were blended with other ingredients to increase spreadability, reduce calories or cholesterol/saturated fat, etc. A few plain butters were enhanced with "butter flavor" - say what? And on no package could it be determined if the butter came from cows that were naturally fed on pasture or on grain in confined pens.

Well said, Anna.

There's a huge supermarket about 1 mile away from my house similar to the one Anna describes with aisle after aisle of eye-catching cellophane-wrapped foods. I go there about every 3 or 4 months, and then I only go to get something I need in a pinch. Every time I go, I too am reminded just how many products there are that look more like junk food than real food.

But there's no real money in real food. Who gets rich off of selling green peppers, tomatoes, and eggs?

Supermarkets sell these modern industrial foods because people buy it: Look around you. You don't get to be a 250 lb 5 ft 2 inch-woman by eating too many cucumbers.

Like Anna, I drive an additional several miles to Trader Joes', buy at farmers' markets whenever possible, buy some odds and ends like wine and cheese and raw nuts at specialty stores. I grow my own basil in a big pot I keep in the kitchen and we are just about to start turning over the soil in the back yard for our vegetable garden. I don't need nor do I miss having the choice among 40 different chips, 25 brands of ready-made microwavable dinners, an entire aisle of breakfast cereasl (all of which are virtually the same with different names and labels), or 75 varieties of salad dressing.

The supermarket for me--and I hope for many of you--has become a place rarely frequented, and only for the odd forgotten item. Oh, I forgot the dog chewies the grocery does have--my dogs love them. So perhaps they are good for something after all.

Sterols should be outlawed

14. March 2009 William Davis (10)

While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.

Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
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.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.

Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.

The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:

Each Nature Valley Healthy Heart Bar contains 400 mg sterols.

HeartWise orange juice contains 1000 mg sterols per 8 oz serving.

Promise SuperShots contains 400 mg sterols per container.

Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.

MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.

Kardea olive oil has 500 mg sterols per 14 gram serving.

WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.

Texas today, tomorrow . . . the world?

Texas state representative, Rene Oliveira, has introduced legislation that mandates heart scans for adults in the state of Texas.

Rep. Oliveira

A press release from the SHAPE Society ( Society for Heart Attack Prevention and Eradication) reads:

Assessment of heart attack risk on the basis of traditional risk factors alone such as high cholesterol and high blood pressure and so forth, while useful, misses many who are at high risk and also incorrectly flags some for high risk who are in fact at very low risk of near term heart attack; on the other hand detection of atherosclerosis by non-invasive imaging, as suggested by the SHAPE group, accurately identifies plaque and improves the ability to identify at-risk individuals who could benefit from aggressive preventive intervention while sparing low-risk subjects from unnecessary aggressive medical therapy," said Dr. P.K. Shah, Director of Cardiology at Cedars Sinai Heart Institute in Los Angeles, a leading member of the SHAPE Task Force who is also an active member of the American Heart Association. "Sadly, these vulnerable patients go undetected until struck by a heart attack, because insurance companies don't cover the newer heart attack screening imaging tests."

Rep. Oliveira, whose coronary disease was first uncovered by a heart scan and prompted a bypass operation, states:

"It is about time that we cover preventive screening for the number one killer in Texas, and take action to reduce healthcare costs through preventive healthcare. Right now, we are extending the lives of those who can afford the procedure while hundreds of thousands of Texans with hidden heart disease go undetected because of antiquated thinking. The time has come for this change."

Is this what we've come to? Since practicing physicians are either so entranced by the drug and procedural solutions to heart disease, do we need to resort to heart scan by legislation?

It does indeed appear that we've come to this point. Should this trend catch on, it will surely mean an upfront increase in healthcare costs to cover the expense of heart scans. But in the long run, it will mean reduction in healthcare costs--dramatic reduction--if heart scans prompt effective preventive action.

What your doctor doesn't know about heart disease

9. March 2009 William Davis (12)

What causes coronary heart disease or coronary atherosclerotic plaque, this thing that we track with heart scans?

Well, here are a few little-publicized facts about heart disease that you are unlikely to hear from your When's-the-next-stent? cardiologist or the What is there besides statins? primary care doctor.

(Since everybody knows that smoking is a modifiable risk for heart disease that can be readily identified, let's focus on the blood tests that reveal heart disease causes.)

What's the number one most common cause for heart disease?

Small LDL particles. The proliferation and popularity of the snack food/processed food culture, compounded with the "eat more healthy whole grain " propaganda has launched small LDL solidly to first place as the most common reason to have heart attacks, stents, and bypass. All that advice to increase your "healthy whole grain" intake? It increases heart attack risk.

What's the number one most aggressive cause for heart disease?

That's lipoprotein(a), or Lp(a). It's certainly not high cholesterol, though the drug industry loves that you think that. We could argue over whether smoking is more aggressive, but the two are pretty darned close. Combine the two--Lp(a) in a smoker--and the combination is an explosively powerful trigger for heart disease and stroke.

What's the number two cause for heart disease?

After small LDL comes low HDL cholesterol. Ask anyone who has had a heart attack: What was your cholesterol panel like? 9 out of 10 will say "My LDL cholesterol was 135 mg/dl" while knowing little or nothing about HDL, which is commonly in the 30-42 mg/dl range--sufficient to contribute to heart disease risk considerably.

Can "normal" thyroid hormone tests still contribute to heart disease?

Yes. Hypothyroidism is an exceptionally powerful risk factor for heart disease. Many people have been told that their thyroid tests are "normal," when in reality risk for heart disease may be as much as tripled from low thyroid with thyroid blood tests in the "normal" range.

Does a "balanced, healthy diet" prevent heart disease?

No, it does not. In fact, the modern notion of a "balanced, healthy diet" increases risk for heart disease. Of course, the dangers of such diets vary, depending on how you define it. If it's the diet advocated by the USDA Food Pyramid, then it is an enormously destructive diet that causes your health to careen towards both diabetes and heart disease. The American Heart Association TLC diet is little better.

Does eating fish twice a month reduce heart attack risk?

Yes, it does--but just barely. Unfortunately, large studies that show that eating fish as infrequently as twice per month reduce risk for dying from heart attack have led some authorities to suggest that's all you need to do. What they fail to understand is that the benefit is dose-dependent--the greater the intake of omega-3 fatty acids, the greater the benefit (within reason, of course). So, while the effect can be detected by eating fish twice per month, it doesn't mean that full benefits are achieved with this "dose." Full benefits are obtained by mimicking the omega-3 intake of the Japanese.

Do nutritional supplements reduce risk for heart attack?

If you are referring to vitamin D, then, yes, nutritional supplements reduce risk for heart attack . . . enormously. We need more data to validate this phenomenon, though epidemiologic observations strongly bear this out, including the Health Professionals Follow-up Study, the Framingham Heart Study and NHANES, all of which demonstrate a graded effect: the lower the vitamin D blood level, the greater the risk for heart attack.

Over the years, we've experienced more than our share of disappointments in nutritional supplements for heart disease, including vitamin E and B vitamins to reduce homocysteine. But I believe that nothing approaches the solid feel of vitamin D--no other nutritional supplement raises HDL, reduces triglycerides, reduces blood sugar, enhances insulin responses, reduces the inflammatory C-reactive protein, reduces blood pressure like vitamin D. Vitamin D is here to stay--and I'm very grateful.

And don't forget omega-3 fatty acids from fish oil, yet another supplement with unquestioned benefits for reduction of heart attack and death from heart attack.

Why didn't your doctor counsel you on the importance of these issues?

The primary reasons your doctor didn't tell you any of the above:

1) He/she has been persuaded that only drugs are of any real use in health. Nutritional supplements? Hah!

2) Neither the number one cause of heart disease in the U.S.--small LDL particles--nor the most aggressive cause for heart disease--Lp(a)--are corrected by patent-protectable, high profit pharmaceutical agents promoted to your doctor. Instead, these abnormalities can be corrected inexpensively, without prescription. That means no expensive commercials, no media spots, no write-ups in magazines.

3) Your doctor's business is to treat crisis: sore throat, broken ankle, lung tumor, heart attack. Prevent heart disease 10 or 20 years before it shows itself? Heck, no (unless the marketing pull of the drug industry is involved, of course).

It's best that you bear in mind: What your doctor doesn't know can kill you.

Thank you, Dr. Eades

6. March 2009 William Davis (7)

Thanks to some readers of The Heart Scan Blog, I've become acquainted with Dr. Michael Eades' wonderful blog, Health and Nutrition by Dr. Michael R. Eades, MD.

Dr. Eades is co-author (with his wife, Mary Dan Eades, MD) of Protein Power

In one of his conversations, I stumbled on this exchange between Dr. Eades and one of his readers:

Reader: Regarding EBT scans, I looked up the topic on Google and read an informative 5-page article: EBT (Ultrafast CT) Scans - Godsend, or Scam? Dr. Fogoros says that false positives (where the EBT shows the presence of calcium, but the patient has little coronary artery blockage) occur about 50 percent of the time. The next step, if the EBT is positive, is to do a heart catherterization to find out whether there actually is coronary artery blockage. So the odds are that I’d have to worry!

Dr. Michael Eades: The info you got from Google is one of the reasons one shouldn’t get medical information online. As far as I’m concerned the EBT is the BEST way to determine the presence of plaque. If you have a positive calcium score, you have plaque, and there’s an end on’t (as Samuel Johnson would say). Now you may have a low calcium score for your age or you may have a calcium score that doesn’t change, which means you have stable plaque, but if you have a positive calcium score, you have some amount of plaque in your coronary arteries.

And whoever says that the next step to take if you receive a positive calcium score is a coronary artery cath is a real moron. That’s probably the last thing you would want to do if you are asymptomatic. All the cath procedure does is shows whether or not you have a blockage - you can have huge amounts of plaque (which are a disaster waiting to happen) and have a normal cardiac cath.

If you want to get a little more information on the validity of EBT than what you find on Google, take a look at Dr. Davis’ blog or get a copy of his book: Track Your Plaque. I’m not crazy about all of Dr. Davis’ dietary recommendations because he comes to diet from a different perspective than I, but the EBT info in his book is terrific.

Cheers–

Dr. Eades "gets" it. He understands that quantification of coronary plaque is a tool for prevention, not something to be subverted into the service of procedures for the financial benefit of my colleagues.

And I think that he is absolutely correct on the diet discussed in Track Your Plaque--it's due for a revision. I wrote the book in 2003, while we were still locked into the low-fat mindset. Much has changed.

Since then, our enormous experience in metabolic manipulation and lipoprotein analysis has shown that there is a far better way to correct the causes of coronary plaque and seizing hold of heart scan scores. In particular, the explosion of small LDL has prompted major changes in the diet, specifically removal of wheat and cornstarch, the foods that trigger small LDL particles.

(I am still in the midst of negotiations for release of a bigger and better Track Your Plaque II. In the meantime, Track Your Plaque Members can refer to the New Track Your Plaque Diet, Parts I, II, and III.)

Can millet make you diabetic?

5. March 2009 William Davis (10)

If wheat is so bad, what about all the other grains?

First of all, I demonize wheat because of its top-of-the-list role in triggering:

--Appetite--Wheat increases hunger dramatically
--Insulin
--Blood sugar--Wheat is worse than table sugar in triggering a rapid, large rise in blood sugar
--Triglycerides
--Small LDL particles--the number one cause for heart disease in the U.S.
--Reduced HDL
--Diabetes
--Autoimmune diseases--Most notably celiac disease and thyroiditis.

Most other "healthy, whole grains" aren't quite as bad. It's a matter of degree.

Millet, quinoa, oats, sorghum, bulghur, spelt, barley, cornmeal--While they don't trigger appetite nor autoimmune diseases like wheat does (oat can in some people), they still pose a significant carbohydrate load sufficient to generate the other phenomena like excessive insulin and blood sugar responses. The grams of carbohydrate of these grains are virtually identical to wheat: 43.5 grams per 1/2 cup (uncooked). The exceptions are barley, which is especially loaded with carbohydrates: 104 grams per 1/2 cup, while oats are lower: 33 g per 1/2 cup.

It's all a matter of degree. Some people who are exceptionally carbohydrate-sensitive (like me) can have diabetic blood sugars with just slow-cooked oatmeal or quinoa. Others aren't quite so sensitive and can get away with eating them.

People with high blood sugars (100 mg/dl or greater) can be very sensitive to the blood sugar effects of these grain carbohydrates. The best marker of all are small LDL particles measured on a lipoprotein panel, such as NMR. Small LDL particles are exquisitely sensitive to your carbohydrate intake: small LDL gets worse with excessive sensitivity to grain carbohydrates, gets better with reduction or elimination.

Flagrant small LDL, in combination with low HDL, high triglycerides, and pre-diabetic or diabetic patterns all develop from carbohydrate indulgence, along with "wheat belly."

Don't believe it? The prove it to yourself: Go to Walmart and buy an inexpensive glucose meter and check your blood sugar one hour after eating. You can gauge the health of these foods by observing the blood sugar increases. (Small LDL closely parallels blood sugar rises.)

The grain that fails to trigger any of these abnormal patterns? Flaxseed. Flaxseed is entirely protein, fiber, and healthy oils, with virtually no digestible starches. In fact, flaxseed is one of the few foods that reduces the quantity of small LDL particles.

Are you a tree?

5. March 2009 William Davis (6)

I assume you answered no. Then why would you consider taking the plant form of vitamin D (ergocalciferol)? That's the prescription form of vitamin D, often dispensed as 50,000 unit tablets.

There's nothing wrong with plants. Some of my favorite foods are plants, full of nutritional value.

Then why shouldn't vitamin D2 from plants be every bit as good as the human form of vitamin D?

I believe the issue boils down to taking hormones from non-human sources. (Remember: Vitamin D is a hormone, a very powerful one at that.) Plants can be wonderful sources of flavonoids, fibers, protein, fats, vitamins, minerals, and other healthy components. But hormones?

There are other examples of non-human hormones being given to humans with undesirable or unpredictable effects:

--Xenoestrogens, phytoestrogens, and non-human mammalian estrogens--While non-human estrogens may partially mimic human estrogens, they can also block estrogen effects, or exert altogether novel effects. Non-human mammalian estrogens like Premarin can exert very peculiar (side-)effects, despite their role as prescription estrogen supplementation in humans.

--Progestins--The synthetic versions of human progesterone, like their non-human estrogen counterparts, exert weird effects that are a world apart from real progesterone.

--Sterols--Similar in structure to human cholesterol (while not a hormone, a building block for hormones), sterols have been used to reduce intestinal cholesterol absorption. However, if sterols are absorbed into the blood, they can enormously accelerate growth of atherosclerotic plaque.

--Anabolic steroids--These modifications of the testosterone molecule build muscle, but also cause liver cancer, kidney failure, violent behavior, suicide and homicidal behavior. That's not normal.

Outside of a pharmacologic effect (e.g., prednisone in place of human cortisol), there is no reason to take a non-human hormone in place of a human hormone. For that same reason, there is NO reason to take plant vitamin D2 (prescription or over-the-counter) in place of human vitamin D3.

If the non-human hormone is identical to the human form, then there is no difficulty. The best example of this are thyroid hormones from pigs. That's what Armour Thyroid is, a thyroid hormone replacement that works wonderfully well.

You will notice that virtually all of the examples of non-human hormones substituted for human hormones share one common motivation: profit. Synthetic or modified versions are more readily patent-protectable, unlike their natural counterparts which are not.

Vitamin D2 is an anemic facsimile of the real human hormone, vitamin D3 (cholecalciferol). Stay away from it.
