Can I stop my Coumadin?

5. September 2010 William Davis (20)
Here I go again.

While I will try to keep this blog on topic, i.e., coronary heart disease prevention and reversal using nutritional and other natural strategies, I believe that a "critical mass" of frequently asked, though off topic, questions keep cropping up.

One such question revolves around Coumadin, or warfarin.

Somehow, my Nattokinase scam blog post draws traffic about Coumadin. I tried to make the point that a conventional blood thinning agent like Coumadin that undoubtedly has undesirable side-effects cannot be replaced by an agent that has an uncertain track record. In the case of nattokinase, no track record.

To illustrate how far wrong the "nattokinase as replacement for Coumadin" idea can go, here is a question from Anna:


I came across your blog while perusing.

I am a bit bummed because I have been on Coumadin (warfarin) for around 22 years since I was 6 years old. I have a mechanical heart valve (St. Jude's), as I have heart-related issues, including hypertrophic obstructive cardiomyopathy.

Well, it is just that the warfarin seems to interact with nearly everything. I feel like I can not get the nutrients my body requires. I desire to consume more raw foods and vegan foods, though I do not want anything to damage my heart valve or risk a stroke/heart attack or internal bleeding.

I have been underweight the majority of my life, malnourished , currently am still somewhat underweight, though enjoying food again, as I had what mimicked Crohn's Disease for several years (horrendous pain), from which I am in remission now. I was diagnosed with osteoporosis, which may or may not be caused from consuming warfarin.

Is it possible to get off of warfarin and effectively keep my blood thinned ? I currently take 1.5 mg to 2 mg dosage. Does the warfarin destroy Vitamin K and if so does that mean while on warfarin I never get the Vitamin K nutrients even if I did consume foods with it in it?

Thank you
Anna

No, sorry, Anna. Stopping Coumadin with your unique issues, i.e., a prosthetic mechanical heart valve (likely mitral, judging by your history of hypertrophic obstructive cardiomyopathy, in which the patterns of blood flow ejected from the heart disrupt the natural mitral valve function) and cardiomyopathy, can be fatal. Without blood thinning, the mechanical heart valve can trigger blood clot formation, since it is a foreign object implanted into the bloodstream.

There are no natural alternatives available with track records confident enough to bet your life on. Aspirin nor Plavix are blood thinners, but platelet inhibitors. These two agents, while they work for other forms of arterial (but not venous) blood clot inhibition, will not work for your unique situation.

Likewise, a purported oral lytic agent like nattokinase should not be substituted for Coumadin. Even if there was plausible science behind it, you should demand substantial evidence that it provides at least blood thinning equivalent to Coumadin. Should a blood clot, even a small one, form in or around the prosthetic valve, the valve can stop working within seconds. This can lead to death within minutes.

I believe it would be foolhardy to bet your life based on the marketing--let me repeat: MARKETING--of a "nutritional supplement" by supplement manufacturers eager to make a buck.

Nor are there any other nutritional supplements that can safely replace the Coumadin. I wish that were NOT true, as I am no stranger to the long-term dangers of Coumadin and I am a big believer, in general, in nutritional supplements. I am a BIGGER believer, however, in the truth. Weighing the options available to us today, there really is no rational choice but to remain on Coumadin.

By the way, I tell my patients to eat a substantial amount of green vegetables while they take Coumadin. I know that conventional advice is to reduce or eliminate green vegetables due to their content of Coumadin-antagonizing vitamin K. I think this is wrong, also. Green vegetables are the best foods on earth. They reduce risk for cancer, diabetes, bone disease, and coronary heart disease.

To obtain the benefits of green vegetables without mucking up your blood thinning (your "protime" or International Normalized Ratio, INR), I advise my patients who take Coumadin to eat green vegetables--but do so every day in relatively consistent quantities, so that the protime or INR is not disrupted and remains reasonably constant. It may mean that your total dose of Coumadin may be somewhat higher, e.g., 3 or 4 mg instead of 2 mg, but the dose is immaterial outside of blood thinning. That way, you obtain all the wonderful health benefits of green vegetables while maintaining fairly consistent blood thinning/protime/INR. Coumadin does not block all the health benefits of vegetables, only those related to vitamins K1 and K2.

With regards to protecting yourself from the osteoporosis promoting effects of Coumadin, I would be sure to follow a program of natural bone health, such as the one I discussed in Homegrown osteoporosis prevention and reversal. You will have to be extra careful, however, with the vitamin K2. Ideally, you have a doctor knowledgeable about vitamin K2 who can assist you in managing K2 intake while on Coumadin. This is something you can definitely NOT manage on your own. (I am a big believer in self-managed care, but this is way beyond the limit.)

Lastly, it is my belief that anyone with an inflammatory bowel condition, such as Crohn's disease or ulcerative colitis, should absolutely, positively, and meticulously AVOID WHEAT and all other gluten sources (such as rye, barley, and oats). Even if you test negative for celiac markers (e.g., anti-gliadin antibodies, emdomysium and transglutaminase antibodies), the enhanced intestinal permeability will allow wheat proteins, such as gluten, to gain ready entry into the bloodstream. Not to mention that wheat should have no place in the human diet anyway, in my view.

Homegrown osteoporosis prevention and reversal

1. September 2010 William Davis (58)
I don't like to stray too far off course from discussions of heart disease and related issues in this blog. But the question of bone health comes up so often that I thought I'd discuss the strategies available to everybody to stop, even reverse, osteoporosis.

Coronary atherosclerotic plaque and bone health are intimately interwoven. People who have coronary plaque usually have osteoporosis; people who have osteoporosis usually have coronary plaque. (The association is strongest in females.) The worse the osteoporosis, the greater the quantity of coronary plaque, and vice versa. The two seemingly unconnected conditions share common causes and thereby respond to similar treatments.

Incredibly, rarely will your doctor tell you about these strategies. Your doctor orders a bone density test, the value shows osteopenia or osteoporosis, and a drug like Fosamax or Boniva is prescribed. As many people are learning, drugs like this can be associated with severe side-effects, such as jaw necrosis (death of the jaw bone), a dangerous and disfiguring condition that leads to loss of teeth and disfigurement, followed by reconstructive surgery of the jaw and face. These are not trivial effects.

Note that drugs are approved by the FDA based on assessment of efficacy and safety, NOT proven equivalence or superiority to natural treatments.

In order of importance (greatest to least), here are strategies that I believe are important to regain or maintain bone health. Indeed, I have seen many women increase bone density using these strategies . . . without drugs of any sort.

1) Vitamin D restoration--Vitamin D is the most important control factor over bone calcium metabolism, as well as parathyroid function. As readers of this blog already know, gelcap forms of vitamin D work best, aiming for a 25-hydroxy vitamin level of 60-70 ng/ml. This usually requires 6000 units per day, though there is great individual variation in need.

2) Vitamin K2--If you lived in Japan, you would be prescribed vitamin K2. While it's odd that K2 is a "drug" in Japan, it means that it enjoys the validation required for approval through their FDA-equivalent. Prescription K2 (as MK-4 or menatetranone) at doses of 15,000-45,000 mcg per day (15-45 mg), improves bone architecture, even when administered by itself. However, K2 works best when part of a broader program of bone health. I advise 1000 mcg per day, preferably a mixture of the short-acting MK-4 and long-acting MK-7. (Emerging data measuring bone resorption markers suggest that lower doses may work nearly as well as the high-dose prescription.)

3) Magnesium--I generally advise supplementation with the well-absorbed forms, magnesium glycinate (400 mg twice per day) or magnesium malate (1200 mg twice per day). Because they are well-absorbed, they are least likely to lead to diarrhea (as magnesium oxide commonly does).

4) Alkaline potassium salts--Potassium as the bicarbonate or the citrate, i.e., alkalinizing forms, are wonderfully effective for preservation or reversal of bone density. Because potassium in large doses is potentially fatal, over-the-counter supplements contain only 99 mg potassium per capsule. I have patients take two capsules twice per day, provided kidney function is normal and there is no history of high potassium.

5) An alkalinizing diet--Animal products are acidic, vegetables and fruits are alkaline. Put them together and you should obtain a slightly net alkaline body pH that preserves bone health. Throw grains like wheat, carbonated soft drinks, or other acids into the mix and you shift the pH balance towards net acid. This powerfully erodes bone. Therefore, avoid grains and never consume carbonated soft drinks. (Readers of this blog know that "healthy, whole grains" should be included in the list of Scams of the Century, along with Bernie Madoff and mortgage-backed securities.)

6) Strength training--Bone density follows muscle mass. Restoring youthful muscle mass with strength training can increase bone density over time. The time and energy needs are modest, e.g., 20 minutes twice per week.

Note that calcium may or may not be on the list. If on the list at all, it is dead last. When vitamin D has been restored, intestinal absorption of calcium is as much as quadrupled. The era of force-feeding high-doses of calcium are long-gone. In fact, calcium supplementation in the age of vitamin D can lead to abnormal high calcium blood levels and increased heart attack risk.

These are benign and easily incorporated strategies. They are also inexpensive. I challenge any drug to match or exceed the benefits of this combination of strategies. Keep in mind that strategies like vitamin D restoration provide an extensive panel of health benefits that range far beyond bone health, an effect definitely NOT shared by prescription drugs.

Your enlarged aorta

27. August 2010 William Davis (19)
The thoracic aorta lives happily within the chest.

The aorta is the main artery of the body that emerges from the heart, located just under the sternum. It is the "tree trunk" from which all the major arteries branch off to the rest of the body: the arms, brain, abdominal organs, pelvis, and legs. The aorta receives the high-pressure blood ejected directly out of the heart muscle.

However, there are evil forces in the body that work to weaken the aorta. When the aorta is weakened, it enlarges. Enlarged aortas also tend to grow atherosclerotic plaque. Plaque in the aorta poses long-term risk for stroke and and mini-strokes ("transient ischemic attacks," or TIAs), due to fragmentation.

There are many enlarged aortas in this world. I see at least several every week. It is fairly common, particularly in people with high blood pressure and cholesterol abnormalities, as well as those who are overweight. Smokers get it really bad.

Conventional thinking is that, once an aorta enlarges, it will inevitably continue to enlarge at the average rate of 2.0 mm per year (resulting in 1.0 cm enlargement over 5 years). For this reason, conventional discussions on the topic of thoracic aortic aneurysms all say something like "Enlarged aortas should be monitored yearly. Surgical replacement should proceed when the aorta reaches a diameter of 5.5 cm."

This is because an aortic diameter of 5.5 cm is associated with much greater likelihood that the aorta will rupture (fatal within minutes) or the internal lining will tear, a "dissection." The surgery is a major undertaking that involves opening the chest and usually replacing the aortic valve and inserting a synthetic aorta. The procedure is high-risk, especially if any branch arteries are involved.

So putting a stop to any further aortic enlargement is a worthwhile goal. Unfortunately, conventional thought is that there is nothing you can do to stop the inevitable growth of the thoracic aorta.

Nonsense. There are a number of efforts you can make to halt further increase in aortic diameter. (My experience in this is anecdotal and unpublished, but now numbers several hundred patients.)

There are two categories of factors that cause the aorta to increase in diameter:

1) Internal pressure--Think of blood pressure as the internal inflating pressure on this "balloon." Keeping the "inflating pressure," i.e., blood pressure, low exerts substantial effect on slowing growth of aortic diameter. I aim for normal BP or lowish BP (less than 130/80, preferably 100/70).

2) Factors that weaken the aortic wall--Processes like inflammation, glycation, lipoprotein deposition, and nutritional deficiencies will serve to weaken the supportive tissue of the aorta. For that reason, correction of lipoprotein abnormalities (e.g., small LDL and lipoprotein(a)), reductions in carbohydrate intake and thereby blood glucose/glycation, and "normalization" of vitamin D, vitamin C supplementation (for collagen crosslinking), and omega-3 fatty acids all play a role.

To push even farther, there may be additional advantage to following strategies that impair the production and activity of a crucial enzyme that lives within the aortic wall: matrix metalloproteinase, or MMP. MMP degrades the collagen and other supportive tissues within the aorta, weakening it and permitting expansion. Blocking MMP may prove to be among the most powerful new strategies to halt aortic expansion.

Compounds that have potential MMP-inhibiting effects include:
--Vitamin D--A substantial effect
--Resveratrol--One of the polyphenols from red wine
--Doxycycline--This old antibiotic often used for acne treatment has, in preliminary studies, shown important MMP-blocking effects and slowed aortic expansion.

Anyway, there you have it. A bit complicated, but a "recipe" that has failed me only rarely.

Extreme carbohydrate intolerance

25. August 2010 William Davis (26)
Here's an interesting example of what you might call "extreme carbohydrate intolerance."

May is a 44-year woman who has now had her 7th stent placed in her coronary arteries. She lives on a diet dominated by breads, breakfast cereals, muffins, rice, corn products, along with some real foods.

Her conventional lipid panel and other lab values:

Total cholesterol 346 mg/dl
Triglycerides: 877 mg/dl
HDL cholesterol: 22 mg/dl
LDL cholesterol: incalculable
(Recall that LDL cholesterol is usually a calculated, not a measured value. The excessively high triglycerides make the standard calculation invalid--more invalid than usual.)

Fasting blood glucose: 210 mg/dl
HbA1c (a reflection of previous 60-90 days average glucose): 7.2% (desirable 4.5% or less)
ALT (a "liver enzyme"): 438 (about five-fold normal)


At 5 ft even and 138 lbs (BMI 27.0), May appears small. But the modest excess weight is all concentrated in her abdomen, i.e., in visceral fat.

By lipoprotein analysis via NMR (Liposcience), May's LDL particle number was 2912 nmol/L, or what I would call a "true" LDL of 291 mg/dl. (Drop the last digit.) Of the 2912 nmol/L LDL particles, 2678 nmol/L, or 92%, were small.

The bad news: This pattern of extremely high triglycerides, extremely high LDL particle number, low HDL, predominant small LDL, and diabetes poses high-risk for heart disease--no surprise. It earned her 7 stents so far. (Unfortunately, she has made no effort whatsoever to correct these patterns, despite repeated advice to do so.)

The good news: This collection is wonderfully responsive to diet. LDL particle number, small LDL, triglycerides, blood glucose, and HbA1c drop dramatically, while HDL increases. Heart disease will at least slow, if not stop.

It's amazing how far off human metabolism can go while indulging in carbohydrates, particularly a genetically carbohydrate-intolerance person. (Actually, I wouldn't be surprised if May's diet, as bad as it seems to you and me, still fits within the dictates of the USDA food pyramid.) The crucial step in diet to correct this smorgasbord of disaster is elimination of carbohydrates, especially that from wheat, cornstarch, and sugars.

What's for breakfast? Egg bake

20. August 2010 William Davis (42)
Heart Scan Blog reader and dietitian, Lisa Grudzielanek, provided this recipe in response to the post, What's for breakfast?

Lisa, by the way, is one of the rare dietitians who understands that organizations like the American Dietetic Association have made themselves irrelevant. She therefore advocates diet principles that work, not just echoing the idiocy that emanates from such organizations, often driven by economics more than science. Lisa works in the Milwaukee area and has proven a useful resource person for my patients who have required extra coaching in the Track Your Plaque diet principles.

Egg Bake
My favorite breakfast is what I call an "egg bake." Others may refer to it as a "quiche."

Take a variety of fresh vegetables. This time of year is great for farmers' markets.

I typically use fresh chopped organic spinach, bell peppers, red & white onions, scallions, broccoli, mushrooms, cherry tomatoes halved and, if desired, meat (nitrite-free ham or leftover chicken breasts).

1) Chop veggies and place in casserole dish.
2) Add meat and handful of cheese of your choice.
3) Scramble 8 eggs & little bit of milk & pepper.
4) Add to casserole dish and mix/coat veggies with egg mixture.
5) Put in oven at 450 degress for 30 minutes.

Yummy, ready to eat breakfast that is so easy for the work week.

What's for breakfast?

14. August 2010 William Davis (0)
If you eliminate wheat from breakfast and otherwise adhere to a low-carbohydrate dietary approach, what is there to eat for breakfast?

If you take out English muffins, bagels, all breakfast cereals, pancakes, waffles, and toast, what's left to eat?

Actually, there's plenty left to eat. It just may not look like the traditional American notion of "breakfast." (The traditional idea of breakfast was is, in part, due to the legacy of Dr. John Harvey Kellogg, who, in the latter part of the 19th century, ran a sanitarium in Battle Creek Michigan. He and his brother, Will Keith Kellogg, discovered the idea of turning grains into flakes, the birth of the breakfast cereal. Subscribe to the idea of breakfast cereal for breakfast and you subscribe to the ideas of a man who would administer four enemas for you today to cure your cancer or rheumatism.)

Here are a few ideas. By no means is this meant to be a comprehensive list, just a starting point for a few new breakfast food ideas.

--Eggs--Of course, eat the yolk. Eat three yolks. Scrambled, "fried," (not really deep-fried, of course), hard-boiled, poached, as an omelette. Add pesto, olive oil, vegetables, mushrooms, salsa.

--Ground flaxseed--As a hot cereal with your choice of water, milk (not my favorite because of insulin effects; the fat is immaterial), full-fat soy milk (yeah, yeah, I know), unsweetened almond milk. Add walnuts, blueberries, etc. Ground flaxseed is the only grain I know of that contains no digestible carbohydrates.

--Lunch and dinner--Yes, if you cannot have breakfast foods for breakfast, then have lunch and dinner, meaning incorporating foods you ordinarily regard as lunch and dinner foods into your day's first meal. This means salads, leftover chicken from last night, soup, raw vegetables dipped in hummus or guacamole, stir fry, etc.

--Cheese--For something quick, grab a chunk of gouda or emmentaler along with a handful of raw almonds, walnuts, or pecans. Because of the excess acidity of cheese (along with meats, among the most acidifying of foods), I usually try to include something like a raw pepper or avocado, foods that are net alkaline.

--Avocados--Cut in half, scoop out contents. They're quick and delicious, when available.

I hesitate to mention it, but I sometimes will have tofu, cubed and flavored with whatever is available--soy sauce, miso, pickled vegetables. My mother was Japanese, so I'm comfortable with this, though many people are not.

Anyway, that's a partial list that nonetheless can get you started on a wheat-free, low-carb breakfast.

If you are just starting out, you will notice a number of fundamental changes. You may first experience the characteristic "withdrawal" effect: mental fog and fatigue that lasts about a week. Energy then picks up, often substantially. This is followed by gradually reduced appetite: You will be far less hungry. You will require less food, less often, since appetite will be driven by physiologic need, not the appetite-stimulating properties of wheat (and cornstarch, high-fructose cornsyrup and sucrose).

By the way, do not skip breakfast unless it's part of an occasional fasting effort. Skip breakfast, wind down metabolism, get fat. I am impressed at how consistent skipping breakfast backfires in those who think that it helps you control weight.

I also welcome any suggestions on what you eat as part of your wheat-free, low-carb breakfast. (Thanks for the great suggestions on the last blog post, Anna.)

Wheat hip

10. August 2010 William Davis (39)
You've heard of wheat belly. How about wheat hip?

Recall that the innocent appearing wheat belly is actually a hotbed of inflammatory activity beneath the surface. The visceral fat of the wheat belly, i.e., fat kidneys, fat liver, fat intestines, fat pancreas, produces abnormal inflammatory signals, such as various interleukins, tumor necrosis factor, and leptin. These are the inflammatory signals that create insulin resistance and diabetes, heart disease, hypertension, and cancer.

These same inflammatory mediators are able to enter the joint spaces, such as those in your hips, knees, and hands. This leads to osteoarthritis, the exceptionally common form of arthritis that affects 1 in 7 Americans. In particular, the level of leptin in joints mirrors that in blood, a phenomenon that has been associated with joint destruction.

The previously widely-held notion that arthritis is simply a wear-and-tear phenomenon due to the mechanical stress of excess weight is proving to be an oversimplification. Arthritis is also part of the carbohydrate-driven, weight-increasing, inflammatory condition of insulin resistance or metabolic syndrome.

Throw into this cytokine storm the fact that glycation, i.e., glucose modification of proteins, also causes cartilage destruction. The cells of human cartilage lack the ability to divide, so the cartilage cells you had at age 18 are the cartilage cells that you will hopefully still have at age 80. However, high blood sugars (glucose) glycate the proteins in cartilage. (Wheat raises blood glucose higher than almost all other foods, higher than a Milky Way bar, higher than a Snickers bar.) The process is irreversible and cumulative. Because cartilage has next to no capacity for repair or regeneration, it becomes brittle. Over years, it essentially crumbles, leading to the "bone on bone" that prompts conversations about total hip and total knee replacement.

So that ciabatta or blueberry muffin in your mouth takes you a step or two closer to joint destruction via heightened inflammation arising from the visceral fat of the wheat belly, worsened by glycation of high blood sugars after carbohydrate consumption.

My solution: Lose the ciabatta.

Men's lingerie is on the second floor

7. August 2010 William Davis (33)
Consume wheat products, like poppyseed muffins, raisin bagels, and whole grain bread, and you trigger the 90- to 120-minute glucose-insulin cycle.

Blood glucose goes way up (more than almost any other known food), triggering insulin release from the pancreas. Glucose enters cells as a result, blood glucose plummets. You get hungry, shaky, and crabby, reach for another wheat or other sugar-generating food to start the roller coaster ride all over again.

Repetitive insulin triggering grows this thing I call a "wheat belly," the protuberant, hang-over-the-belt fat you see everywhere nowadays. Wheat belly fat is really visceral fat. Visceral fat means you have fat kidneys, fat intestines, fat pancreas, and fat liver, all causing the belly to protrude in the familiar way we've all come to recognize.

Visceral fat is special fat. Unlike the fat in the backside, thighs, or arms, visceral fat triggers inflammatory responses that are evident in such measures as tumor necrosis factor, interleukins, and leptin, as well as drops in the protective hormone, adiponectin.

Visceral fat also, oddly, triggers estrogen release. Estrogen triggers growth of breast tissue. That's why females with wheat bellies have up to four-fold (400%) greater likelihood of breast cancer.

Men also experience excess estrogen from the visceral fat wheat belly, causing "man boobs." This B-cup phenomenon means that inflammation is raging beneath the surface, all due to this thing you're wearing around your waist.

I wasn't aware until recently that male breast reduction surgery is a booming business growing at double-digit rates. So are special clothes to help men conceal their expansive breasts.

Perhaps the USDA is in cahoots with Playtex.

10,000 units of vitamin D

3. August 2010 William Davis (47)
Joanne started with a 25-hydroxy vitamin D level of 23 ng/ml--severe deficiency.

What made this starting value even worse was that it was drawn in August after a moderately sunny summer spent outdoors. (Last summer, not this summer.) It therefore represented her high for the year, since vitamin D levels trend lower as fall and winter set in. This suggests that her winter level was likely in the teens or even single digits. In addition, note that, at age 43, Joanne has lost much of her ability to activate vitamin D in the skin.

So I advised that she take 6000 units of an oil-based gelcap per day, a dose likely to generate the desired blood level, which I believe is 60-70 ng/ml.

Four months later, her 25-hydroxy vitamin D level: 39.9 ng/ml--still too low. So I advised her to increase her dose to 10,000 units per day. Several months later, her 25-hydroxy vitamin D level: 63.8 ng/ml--perfect.

However, on hearing that she was taking 10,000 units vitamin D per day, Joanne's primary care physician was shocked: "What? Stop that immediately! You're taking a toxic dose!" So Joanne called me to find out if this was true.

No, of course it's not true. It's not the dose that's toxic, but the blood level it generates. Although it varies, vitamin D toxicity, as evidenced by increased blood calcium levels, generally does not even begin to get underway until at least 120-130 ng/ml, perhaps higher. Rarely, a dose of 2000 units per day will generate a level this high. In others, it may require 24,000 or more units per day to generate such a high level.

So it's not the dose that's toxic, but the blood level of 25-hydroxy vitamin D it generates.

Provided you and/or your doctor are monitoring 25-hydroxy vitamin D blood levels, the dose is immaterial. It's the blood level you're interested in.

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?

Are endogenous nutritional supplements better?

4. May 2008 William Davis (6)
Just a muse.

Endogenous substances are those that are already contained within our bodies. They are part of basic human equipment.

Exogenous substances are those that come from outside of our bodies. This includes various substances in foods, drugs (most, though not all), and pesticides.


I often mull over all of the tools we use in the Track Your Plaque program to achieve control over this thing called coronary plaque. It struck me that just about all the supplements we use that seem to provide outsized benefits are all endogenous substances themselves:

--Omega-3 fatty acids from fish oil
--Vitamin D
--l-arginine
--Niacin (vitamin B3)

Many of the other substances, though not directly relevant to our plaque-control efforts, but are among the most effective nutritional supplements, also supplement endogenous levels: calcium pyruvate, creatine, acetylcarnitine, DHEA, testosterone, progesterone, growth hormone, pregnenolone, phenylalanine, tyrosine, melatonin, etc.

Curiously, most drugs are not meant to directly supplement endogenous levels, but are designed either to enhance or block an enzyme (e.g., acetylcholinesterase inhibitors that block breakdown of acetylcholine; HMG CoA reductase inhibitors to block cholesterol synthesis; angiotensin converting enzyme inhibitors to reduce blood pressure), to exert toxic effects on an organism (antibiotics, antivirals), or to exert an entirely unique effect that does not ordinarily occur in the human body (some anti-cancer drugs, for instance). (This is an admitted, vast over-simplification.)

That's not to say that any endogenous substance is desirable or safe when supplemented. Cortisol, thyroid hormone, and estrogens are three examples of endogenous substances that have downsides when administered at slightly more than physiologic concentrations.

Nonetheless, it makes me wonder if the world of endogenous substance supplementation has not been fully explored. Are there other endogenous substances that are as potent and wonderful, for instance, as vitamin D but not yet fully appreciated? I'm sure there are.

Vitamin D Newsletter reprinted

1. May 2008 William Davis (2)
Reprinted here is the unfailingly informative Vitamin D Newsletter from Dr. John Cannell. Although there's little here specifically about heart disease, there's so much great information about vitamin D that I thought most would still appreciate it.



The Vitamin D Newsletter

May, 2008

Yesterday's Washington Post article, Too-Good-To-Be-True Nutrient?, sums up the April 9th vitamin D symposium at UCSD in San Diego, which was nothing short of spectacular. Carole Baggerly outdid herself organizing it and explaining how she got involved. Make no mistake; Carole is both serious and energetic. She told about her efforts to introduce resolutions at upcoming meetings of various professional groups. Then she introduced the volunteers from the San Diego Black Nurses Association who made sure the conference went off without a hitch. Then Carole introduced the four speakers. The slides of each speaker are available at Grassroots Health.

Before I tell you the highlights of the conference, I'd like to tell you about another conference, this one in Germany, this May 17th and 18th. It is the Third International Symposium on Vitamin D Analogs in Cancer Prevention and Therapy. Readers know how I feel about giving analogs to vitamin D deficient patients instead of vitamin D but speakers include Michael Holick, Reinhold Veith, Bill Grant, Tai Chen, Heidi Cross, David Feldman, and Roger Bouillon, all of whom know the importance of the nutrient. Most of this conference is for scientists, not lay people. However, Michael Holick is the first speaker and if you have not heard his latest talk about vitamin D, it might be worth a trip to Germany.

The first San Diego speaker was Dr. William Grant. Since leaving NASA to begin a full-time career as a vitamin D researcher, Bill has published dozens of studies and has another dozen in the works. Using ecological studies (from Greek oikos, house + German -logie, study or studying your own house) of UVB irradiance and cancer, Bill reported that 15 cancers (colon, esophageal, gallbladder, gastric, pancreatic, rectal, small intestinal, bladder, kidney, prostate, breast, endometrial, ovarian, Hodgkin's lymphoma, and non-Hodgkin's lymphoma) are associated with lower UVB light. He concluded that 257,000 cancer deaths in 2007 in the USA were accounted for by inadequate vitamin D levels. Of course the problem with ecological studies is that it easy to be vitamin D deficient in Miami, all you have to do is listen to your doctor's advice and stay out of the sun. Recently, a group from the Arizona Cancer Center found almost 80% of Arizonians had levels below 30 ng/ml. So much for sunny spots.

Jacobs ET, et al. Vitamin D insufficiency in southern Arizona. Am J Clin Nutr. 2008 Mar;87(3):608-13.


The next speaker was Professor Cedric Garland. I found myself wondering how he did it. I became convinced that vitamin D prevents cancer five years ago. Cedric and his brother Frank and his colleague Ed Gorham knew it 30 years ago! I know what it is like to tell someone that vitamin D prevents cancer and see them think, "Here we go again, another miracle vitamin." I know what it is like to try and explain and watch people die unnecessarily. But I've only had that experience for five years. Cedric has dealt with that frustration for thirty years. Almost thirty years ago, Cedric and Frank Garland published evidence that vitamin D prevents cancer. In fact, it was Cedric's first publication. Thankfully, the paper was recently recognized as being so important that it was republished in 2006 by the International Journal of Epidemiology. You can read the entire paper for free by clicking on the second link below and then clicking on "free final text", courtesy of Oxford Journals.

Cedric began by showing the incidence of type-1 diabetes and multiple sclerosis by latitude. I had no idea that the latitudinal data was so strong for type 1 diabetes in children. This disease is almost nonexistent around the equator. Type-1 diabetes is but one of the three modern childhood epidemics caused by the sunlight-hating dermatologists, the other two, I think, are autism and asthma. Next he showed latitude and 25(OH)D levels, which reminded me to be suspicious of high levels, unless they use accurate methods of detecting 25(OH)D. Some methods used, even in this country, are over detecting vitamin D and telling patients their levels are above 50 ng/ml when they are, in reality, much lower. Cedric's data showed Thailand had mean levels of 70 ng/ml, which I doubt and suspect were due to inaccurate 25(OH)D tests. He then reviewed evidence of the 25(OH)D levels needed to prevent numerous cancers. The safest levels are somewhere above 50 ng/ml. Cedric spent most of his time presenting an entirely new theory of carcinogenesis, one dependent on vitamin D maintaining cellular junctions. I suspect this paper will also be reprinted in 20 years. The only disagreement I have is with his recommendation for cancer patients to start at fairly low doses. For reasons I recently explained, the risk benefit analysis indicates cancer patients should take 5,000 to 10,000 IU per day and they may have no time to lose. Why worry about the phantom of vitamin D toxicity if you may be dying of cancer? Just have your calcium checked along with frequent 25(OH)D levels. Get your levels up to 70-90 ng/ml if you have cancer.



Does vitamin D treat cancer?

The next speaker was Professor Bruce Hollis. He reviewed basic physiology of vitamin D and emphasized that the entire system is designed to deal with an excess not with an insufficiency of vitamin D. Numerous mechanisms are available in your body to prevent vitamin D toxicity but few are available to deal with insufficiency. Then he briefly mentioned one of the most important discoveries about vitamin D in the last few years, one where Professor Neil Binkley of the University of Wisconsin was senior author. (In the last four years, Professor Binkley has become a prolific vitamin D expert and I hope Carol Baggerly is able to get him to speak at some of the upcoming conferences she hopes to sponsor.) As I have pointed out before, Hollis and Binkley's crucial discovery was that the body doesn't start storing the parent compound, cholecalciferol, until 25(OH)D levels reach about 50 ng/ml. They showed, using basic steroid pharmacology, that 50 ng/ml should be considered the lower limit of adequate 25(OH)D levels.

Hollis BW, Wagner CL, Drezner MK, Binkley NC. Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-4.


Bruce kept the audience enthralled with a review of all the disease states that indicate 25(OH)D levels need to be much higher than they are now, that is, the multiple biomarkers that suggest the lower limit of 25(OH)D levels should be above 40 ng/ml and closer to 50 ng/ml. Then Professor Hollis spoke of his ongoing study in pregnant women and how he got approval to use 4,000 IU of vitamin D per day back in 2003, quite an accomplishment. He also reviewed another one of his research projects, one that answered an age old question, why is breast milk a poor source of vitamin D? How were prehistoric infants supposed to get their vitamin D, by lying out in the sun where saber tooth tigers would eat them? No, they were hidden in caves and had to have another source or the human race would have died out long ago because rickets destroys a woman's and infant's chance to live through childbirth due to rachitic deformations of the mother's pelvis. Carol Wagner and Bruce Hollis, together with their colleagues, answered that age old question, human breast milk is a poor vitamin D source because virtually all modern mothers are vitamin D deficient. That is, when pregnant women keep their levels where we think prehistoric human levels were, about 50 ng/ml, breast milk becomes a rich source of vitamin D. First Carol and Bruce gave 2,000 IU per day, then 4,000 IU per day and finally 6400 IU of D3 per day to lactating women. Only at 6400 of D3/day did the women maintain both their own 25(OH)D levels and the levels of their breast feeding babies above 50 ng/ml. On 6400 IU/day, the vitamin D activity of the breast milk went from about 80 to 800 IU/L. Quite a discovery, and another reason for all of us to keep our levels above 50 ng/ml.

Professor Robert Heaney went last, discussing 74 slides. So much of what we know about vitamin D today is due to Robert's unceasing dedication to vitamin D, the most recent example being his and Joanne Lappe's randomized controlled trial showing that increasing baseline levels from 29 to 38 ng/ml reduced the risk of getting cancer by around 70%. He again pointed out that the body does not begin to consistently store much vitamin D until your levels get to around 50 ng/ml. He also went through multiple biomarkers of vitamin D. That is, what level or intakes do you have to have to reduce the incidence of multiple diseases? He covered calcium absorption, osteoporosis, risk of falling, muscle function, death and disability of the aged, TB, influenza, cardiovascular disease, hypertension, diabetes, cancer, multiple sclerosis, and gum disease. How can one vitamin be involved in so many diseases? Simple said Dr. Heaney, "vitamin D is the key that unlocks the DNA library." He then reviewed toxicity and concluded there is no evidence that it occurs at levels below 200 ng/ml or with intakes (total) below 30,000 IU per day. Of course, we have no reason to think anyone needs 30,000 IU per day or levels of 200 ng/ml, which would be irresponsible. But someone with a serious cancer should consider getting their level up to 70-90 ng/ml and that may take 10,000 IU per day or even more in some people. As a rule of thumb, 1,000 IU will raise 25(OH)D levels by about 10 ng/ml.

Then Professor Heaney addressed a public health question. How much would we have to give all Americans to get 98% of people above 32 ng/ml without causing toxicity in anybody? The answer: 2,000 IU per day. Of course 32 ng/ml is not adequate but it would be a great first step. Furthermore, of the people left out, a high percentage would be African Americans. In fact, Dr. Talwar recently reported that 40% of African American women fail to achieve a level of 30 ng/ml even after taking 2,000 IU/day for a year.

Talwar SA, Aloia JF, Pollack S, Yeh JK. Dose response to vitamin D supplementation among postmenopausal African American women. Am J Clin Nutr. 2007 Dec;86(6):1657-62.


He also discussed his recent study giving healthy adults 100,000 IU as a single dose. If you start with a baseline level of 28 ng/ml and take 100,000 IU as a single dose, mean levels will remain above 32 ng/ml for two months. If you rely on such stoss doses, but you start with a lower level, or want your levels above 50 ng/ml, how often do you need to take 100,000 IU? We don't know the answer to the last question but we know that Grey et al gave 50,000 IU per week for four weeks then 50,000 per month for a year to 21 patients with hyperparathyroidism. Blood levels rose from a mean of 11 ng/ml at baseline to 30 ng/ml at one year and levels did not continue to rise after six months. Remember, that means half the patients had levels lower than 30 ng/ml at the end of the year. Also remember that the metabolic clearance (how quickly you use it up) might be higher in certain disease states.

Grey A, et al. Vitamin D repletion in patients with primary hyperparathyroidism and coexistent vitamin D insufficiency. J Clin Endocrinol Metab. 2005 Apr;90(4):2122-6.


That last point, metabolic clearance, is only one of a number of reasons that patients vary in their response to vitamin D. Remember, a surprising number of patients will tell their physician they are taking vitamin D when they are not, some will be taking preparations that have less in it than the label says, some will not absorb it, and some people weigh more than others. As Dr. Heaney points out, even if you know patients took 100,000 IU, great variably exists in individual response. At the end of two months some will have shown a minimal response and other much more. This is a field where little is known. Do different disease states use up vitamin D quickly? The answer is probably yes. Furthermore, variability also exists in how one metabolizes and catabolizes (breaks down) vitamin D. Also, what is the interactive effect of drugs that use the same liver enzymes for catabolism? We just don't know and that is why vitamin D blood testing is crucial. Remember, the only test to have is a 25-hydroxy-vitamin D. Do not let anyone get a 1,25-dihydroxy-vitamin D; it will not tell you if you are vitamin D deficient and is usually only indicated in evaluating high blood calcium.

As far as 25(OH)D levels go, many of you have written complaining about the high cost of a 25(OH)D levels at some labs. I've got some good news. For the next month, Life Extension Foundation is having a sale on their 25(OH)D blood tests, only $32.25, including the fee for drawing the blood. (No, we don't get funding from Life Extension, I wish we did.) Life Extension uses LabCorp, which, in turn, uses an accurate method to determine 25(OH)D levels, the DiaSorin Laiason method. The only problem is that DiaSorin, LabCorp, and Life Extension all say that 30 ng/ml is acceptable. It is not. Take enough vitamin D or get enough UVB radiation to get your levels above 50 ng/ml. To order the test, call Life Extension at 800 208-3444. Unfortunately, this offer is not available in New York, New Jersey or Rhode Island.

Also, Dr. James Dowd has written a fine book about vitamin D, The Vitamin D Cure. Get this, he is board certified in internal medicine, adult rheumatology, and pediatric rheumatology, an associate professor at Michigan State University, and runs his own Arthritis Institute and the Michigan Arthritis Research Center. He gives a formula for how much vitamin D you need but stresses the importance of testing to know for sure. He uses the formula of 2000 IU for every 100 pounds of body weight, which is as accurate an estimation as one can make without knowing baseline levels. Of course it depends on so many things, as Dr. Dowd points out, such as percentage body fat, latitude, skin type, sun exposure and age. He gives case after case examples of how vitamin D not just prevents disease, but seems to have a treatment effect. He also stresses three other things I've written about before, acid base balance, magnesium and potassium. If you can't get eat enough fruits and green leafy vegetables to obtain your potassium and magnesium and to get rid of low-grade chronic metabolic acidosis, then you should consider magnesium supplements and potassium bicarbonate supplements.

With these four experts and with this month's vitamin D news articles about breast cancer, brain function, artery blockage in the legs, soft skulls in babies, peripheral neuropathy in diabetics, childhood type-1 diabetes, colon cancer, and stress fractures and with the increasing number of scientists around the world jumping on the vitamin D express, why doesn't the government do something? What will it take? Like Carole says it will take a grassroots effort.

The first thing to do is tell your family and friends about vitamin D. Tell your doctor. Get your family's 25(OH)D tested, including your children. Once people begin to see it works, they will get their family and friends to take it. They will feel better and then the word will spread. All the government can do is make vitamin D illegal or limit the amount in each pill. The first is unlikely but not the second. With 5,000 IU capsules widely available, many people give no thought to taking one a day. But if the government limits the sale of anything over 400 IU and people had to take 12 of the 400 IU tablets, instead of one of the 5,000 IU, they might balk at so many pills. Before our officials in Washington take such a step, let's hope they read the Washington Post.

Biggest bang for your nutritional buck

29. April 2008 William Davis (13)
Judging by the conversations here, in the Track Your Plaque Forums, and elsewhere, it's clear that many people are searching for the perfect diet.

Should we reconsider the role of saturated fat? Are there fractions of fatty acids in saturated fat that are more or less harmful? How about the role of fats on cancer risk? How about the role of proteins like casein on cancer risk? Are there flavonoid sources, or combinations of flavonoids, that yield outsized health benefits? Is there a ceiling for omega-3 fatty acid supplementation? Is there a role for linolenic acid sources in cardiovascular disease prevention? And on and on.

All important issues, to be sure, ones that we've all zig-zagged through over the past 30 years.

I also see patients every day, however, who are not interested in micro-managing their diet. Their goals are less ambitious: lose 20 lbs, feel good, raise HDL, reduce triglycerides and small LDL, all while meeting all the other responsibilities in their lives, like children, spouses, maintaining a household and jobs.

So, if your interest is not to consider whether we should distinguish myristic acid sources from palmitic, or if epigallocatechin is better when combined with quercetin, then the biggest bang from your nutritional buck can come from one single strategy:

Eliminate wheat flour products

Secondarily, avoiding corn starch products and "goodies" (candy, fruit juices, fruit drinks, cookies, potato chips, etc.--you know what they are) is important, as well.

It means weighing your diet more heavily in favor of vegetables and fruits; lean meats; healthy oils; and raw nuts and seeds, all in unlimited quantities. Dairy products should be limited, however, because of sugar effects.

Of course, this advice clearly contradicts the pronouncements of the USDA Food Pyramid (6-8 servings of grains per day), the American Heart Association, and the diabetes-causing American Diabetes Association diabetic diets.

But, follow this approach, a diet strategy that appears too simple to be effective, and the majority of people lose dramatic amounts of weight, raise HDL, reduce triglycerides, reduce small LDL, reduce C-reactive protein and other inflammatory measures, reduce blood pressure, and raise self-esteem.

It's also a lot easier than it sounds (after habits are broken) because the appetite stimulating effect of wheat is removed. Many, if not most, people also experience increased energy, including elimination of the afternoon "slump," improved sleep, less mood swings, less intestinal problems.

It may not be perfect, but if your interest is to get the most with a modest amount of effort, it works like a charm for the majority of people.

Can skinny be fat?

29. April 2008 William Davis (6)
You're going to hate this.

Dr. Romero-Corral and colleagues from the Mayo Clinic presented an analysis of the National Institutes of Health-funded National Health and Nutrition Examination Survey (NHANES-3) at the recent American College of Cardiology meetings. (Science Daily also has some coverage on this report.)

Their analysis identified 2127 adults from the NHANES database who had normal body-mass indexes (BMI) between 18.5 and 24.9 units), average age 41 years old. When broken down by percent body fat (measured with bioimpedance, meaning a small electrical current is passed through the body, much like what the store-bought Tanita devices do), with normal-weight obesity defined as >20% body fat in males, >30% body fat in females, 55% of participants met criteria for designation as normal-weight obesity.

Compared to people with similar BMI's but who fell below these body fat percentage cut-offs, the normal-weight obese men had increased ratios of Apo B to Apo A1; were much more likely to have increased blood sugars or be diabetic; have higher C-reactive protein (CRP); were several-fold more likely to meet other criteria for diagnosis of metabolic syndrome; had lower HDL cholesterols; and had higher blood pressure. Women with normal-weight obesity were four-fold more likely to have coronary disease.

While preliminary, this suggests that a substantial number of people with apparently favorable body weights and BMIs are, in actuality, overweight when judged by metabolic parameters. This then probably leads to increased risk for heart disease. We can then fairly readily extrapolate the argument that a reduction in weight to even lower BMIs likely reduces or corrects these patterns.

This argument is similar to that proposed by several others, arguing that BMI is a flawed measure, since it does not incorporate muscle mass or skeletal factors ("big- or small-boned"). Instead, they have argued that waist circumference is preferable.

The normal-weight obesity syndrome was originally identified by Dr. Antonio de Lorenzo and colleagues at the University of Tor Vergata, Rome, Italy, and reported in Normal weight obese (NWO) women: an evaluation of a candidate new syndrome. Their studies of women with this "syndrome" have suggested that heightened measures of inflammation are present despite apparently normal body weight and BMIs. One such report, Normal-weight obese syndrome: early inflammation?, is available in full-text.

Is there a lesson to be learned for the Track Your Plaque program? I believe there is. I believe it means that, if you have any weight-sensitive parameter, such as low HDL, small LDL, high triglycerides, high CRP, high blood sugar, high blood pressure, etc., then further weight loss might be considered, even if BMI is around 25. Obviously, there is a rational limit to how far you can push this concept. (Anorexia is not good for you either.)

I find this a useful concept. It provides yet another potential strategy to pursue when the above patterns are encountered. Perhaps it's also a way to cap reliance on niacin, whose effects closely mimic that of weight loss.

Now that's a lot more preferable to more and more statin drug, isn't it?

Why do morphine-blocking drugs make you lose weight?

Why do morphine-blocking drugs make you lose weight?

10. November 2010 William Davis (24)
Naloxone (IV) and naltrexone (oral) are drugs that block the action of morphine.

If you were an inner city heroine addict and got knifed during a drug deal, you'd be dragged into the local emergency room. You're high, irrational, and combative. The ER staff restrain you, inject you with naloxone and you are instantly not high. Or, if you overdosed on morphine and stopped breathing, an injection of naloxone would reverse the effect immediately, making you sit bolt upright and wondering what the heck was going on.

So what do morphine-blocking drugs have to do with weight loss?

An odd series of clinical studies conducted over the past 40 years has demonstrated that foods can have opiate-like properties. Opiate blockers, like naloxone, can thereby block appetite. One such study demonstrated 28% reduction in caloric intake after naloxone administration. But opiate blocking drugs don't block desire for all foods, just some.

What food is known to be broken down into opiate-like polypeptides?

Wheat. On digestion in the gastrointestinal tract, wheat gluten is broken down into a collection of polypeptides that are released into the bloodstream. These gluten-derived polypeptides are able to cross the blood-brain barrier and enter the brain. Their binding to brain cells can be blocked by naloxone or naltrexone administration. These polypeptides have been named exorphins, since they exert morphine-like activity on the brain. While you may not be "high," many people experience a subtle reward, a low-grade pleasure or euphoria.

For the same reasons, 30% of people who stop consuming wheat experience withdrawal, i.e., sadness, mental fog, and fatigue.

Wouldn't you know that the pharmaceutical industry would eventually catch on? Drug company startup, Orexigen, will be making FDA application for its drug, Contrave, a combination of naltrexone and the antidepressant, buproprion. It is billed as a blocker of the "mesolimbic reward system" that enhances weight loss.

Step back a moment and think about this: We are urged by the USDA and other "official" sources of nutritional advice to eat more "healthy whole grains." Such advice creates a nation of obese Americans, many the unwitting victims of the new generation of exorphin-generating, high-yield dwarf mutant wheat. A desperate, obese public now turns to the drug industry to provide drugs that can turn off the addictive behavior of the USDA-endorsed food.

There is no question that wheat has addictive properties. You will soon be able to take a drug to block its effects. That way, the food industry profits, the drug industry profits, and you pay for it all.

    A doctor friend of mine was telling me about this, junkies hate it because it makes them instantly sober. Interesting that it would block the same receptors involved in wheat addiction.

    Thank you for explaining/exposing this.  For years I've wondered how food addictions work, especially wheat.  That our representative government is serving profit seeking corporate interests no longer surprises me though.

    Thank you for these interesting insights.  

    Now I also know why I couldn't just eat one cookie - - had to continue and eat the whole box.

    Now, without that first cookie, I totally don't care about them at all.

    BTW, naltrexone is also used to treat alcoholism in protocol known as The Sinclair Method.  You take the naltrexone an hour before drinking and then drink normally.  The naltrexone blocks the opoid receptors in the brain and the endorphins released by the drinking find no room at the inn.  Over time, the addiction is extinguished.

    I do not think I could have made up something like this! If I could I would be very rich, and maybe own a Big Pharma company or two.

    BTW, awhile ago, I read about a clinical study done in the UK. It had three groups of heron addicts - one group stayed on heroin, another was given methadone, the third was given a placebo (that they were told was methadone).

    Not surprisingly, the first group remained addicted to heroin, and the second group remained addicted to Methadone. The third group ALL got over their previous addiction to heroin, and with NO withdrawal symptoms, NONE, not one of them.

    Some commentators pointed out that The Heroin Establishment has a very large financial interest in keeping the story alive that heroin is hard to stop.

    I also know someone who was addicted to heroin. But, he realized that he was messing up his life (lost his wife, kids, etc). So, just stopped taking it - NO withdrawal issues, NONE.

    It's not clear to me how much of this is intentional, i.e., is wheat now a ubiquitous component of processed food precisely because of its addictive potential?

    Regardless, wheat stands apart from all other foods for this effect on humans.

    interesting!

    and to think, the Ornishes, Furhmans, and Campbells of the world would have us believe that meat is addictive. Ha!

    Naltrexone..really?  Do some research on this drug and you will find that used over a long period of time it will cause changes to the receptors so that we feel no euphoria ever!  Bad Bad news.

    Eating wheat bread by itself is not very addicting but if sugar is thrown in the mix, you can get a nice mood lift.  This is because sugar(along with the wheat) spike insulin which drives tryptophan into the brain, where it converts to serotonin, the feel good neurotransmitter.

    I may experiment.  I have some naltrexone that is about to expire.  I might give myself an injection and see if it makes me less interested in bread.  At the most I might eat two slices of whole wheat once or twice a week.  Would it work for other carbs like potatoes?

    HI, Kevin--

    I'm impressed that you've got naltrexone! Please let us know what becomes of the experiment.

    Wheat stands apart for this effect. The only other foods that have been shown to exert a morphine-like effect are dairy products ("caseomorphin"), though the potency is many times less than that exerted by wheat.

    I eliminated grains, switched to Almond milk, cut out coffee and all artificial sweeteners.

    I started LDN in June and have easily lost 23 pounds, a feat almost unheard of in a Hashimoto's patient.

    Just a small amount of some protein and veggies will satisfy me but so could a handful of unsalted nuts.
    My appetite is no longer an issue.
    I would say I don't really have an interest in food anymore.
    I no longer have any blood sugar swings but those disappeared when I eliminated grains. I just feel LDN was helping in the appetite area, now your post confirms what I had been feeling.

    Now that my thyroid medication has been switched ( Armour to Synthroid due to manufacturing issues) and adding Cytomel plus LDN, I feel better.

    I am waiting of lab results to see where my Vit. D level is ( was at 42 aiming for 60) and to see what impact 6 months of no grains has done to my cholesterol.
    I am hopeful!  And that's another thing about LDN, depression is a thing of the past.
      
    My holistic MD thinks because the dosage is so small, LDN is acting in a homeopathic manner.  
    Many Hashimoto's patients have to decrease the amount of hormone they take because of LDN's effect on the thyroid.  
    I should know if my thyroid is happier by the end of the month. It might even be too happy.

    Chet - you say wheat is not addicting. My experience is not proof but when I gave up wheat I had about 3 days of withdrawal symptoms.  I felt really terrible and I was still eating sugar and high carb foods. A few years later I gave up the sugars. Although it took a while to lose the cravings for sweets, I did not have a period of feeling ill like I did when I gave up wheat.  

    Giving up wheat eliminated my depression. The tiniest amount of accidental wheat causes my mood to drop for a few days.

    Wrong explanation. By antagonizing opioid receptors, naltrexone disrupts flow in reward circuit. Which we know is central to the development of addiction. Wheat or no wheat. The weight loss appears to be at least in part something else. In combination with buproprion (AKA Zyban, an effective quit smoking drug) it significantly reduces food intake (by blocking hunger signal and reducing cravings). Again, wheat or no wheat.

    I'm trying to understand trade-offs.  Since quitting meat my weight hasn't changed, my blood sugar has improved, and my LDL is worse.

  • Kevin

    11/12/2010 7:35:40 PM |

    I took a closer look.  It's naloxone, not naltrexone.  Very rarely I see a dog that's ingested opiates.  That's why I have it but as I said, the dozen vials have reached the expiration date.

    Sorry, completely off topic but did you see the article in HeartWire re reducing LDL even more.

    The diabetes guru Dr. Bernstein has written about low dose naltrexone therapy (LDN) to help diabetics lose weight.  Have you used LDN with your patients?  I understand that a low dose of naltrexone taken at night at first inhibits endorphin release and then stimulates it.  Presumably, increased endorphins eliminates the need for addictive foods and lowers inflammation.  Your thoughts?

    There is a Scientific American article that says negative emotions and pain-induced negative emotion are processed in the same brain areas so pain medication also relieves emotional pain.

    If wheat has opiate like effects, it might explain "emotional eating".
