Self-empowerment is coming!

I've discussed this before: The coming wave of self-empowerment in health. Health that is driven by you, not a hospital, not a doctor, not by procedures, but by information and access to tools that are powerful and effective.

The seeds are being planted right now and won't take full root for many years or decades. But it's going to happen.

I previously cited several broad trends that are examples of this emerging wave:

--The nutritional supplement movement. Contrary to the media's ill-informed bashing, nutritional supplements are getting better: improved quality, better substantiation of when/how to use them, new agents that appear rapidly, since introduction is not slowed by the molasses of the FDA.

--Medications moving to over-the-counter status. Health insurers are driving this one. OTC means not paid for by insurance. That also means access to you.

--What I call "retail imaging", i.e. screening ultrasound, heart scans, full body scans, etc. that are available in most states without a doctor's order.

--The Internet. The mind-boggling rapidity and depth of information available on the Internet today is fueling the self-empowerment movement by providing sophisticated information to health care consumers. Information here is uneven at present. But, as consumer sophistication increases and the system of checks and balances evolves, internet-driven information will be often superior to what you get from a doctor or other health professional.

--High-deductible health insurance plans. If health care consumers bear more and more of the costs of health care, they will seize greater responsibility for early identification and prevention and minimize long-term costs.

This trend does not mean treating your own infection, taking out your own gall bladder, repairing your own broken leg. It means that conventional routes of health delivery will recede into providing only catastrophic care.

It means that you and your family will take a larger role in learning how to eat and exercise properly, use foods to maintain and promote health (the "designer food" and "nutraceutical" movement), take supplements that have real benefits, use medications for treatment of many everyday ailments.

It also means seizing control of diseases that previously were only treated in hospitals, like coronary heart disease. This, of course, is where our program, Track Your Plaque, is an example of how you can have a powerful and effective role in your heart health. Track Your Plaque goes so far beyond the "eat low-fat, exercise, and know your numbers" media mantra that it's like comparing a brand-new Mercedes to a rusted, run-down '87 Ford Escort. There truly is no comparison. (Sorry if you're an Escort driver!) But you get the idea.

Another option for lipoprotein testing


For those of you who have been frustrated in trying to get your lipoprotein analysis performed, here's another option.

The Life Extension Foundation at www.lef.org provides access to the VAP test, or Vertical Auto Profiler. This is the lipoprotein test run by the Atherotech company in Birmingham, Alabama. The name refers to the method used, a form of centrifugation, or high-speed spinning of your blood (plasma) to separate the various components by density.

This is a fine technique that works well. Though our preferred method is NMR (www.Lipoprofile.com, Liposcience Inc.), the Atherotech VAP is a reasonable alternative.

If you go through the Life Extension process, they will direct you to blood draw sites in your area. They charge $185 for Life Extension members, $247 for non-members. (Membership in Life Extension costs $75.) Drawback: No billing for health insurance reimbursement.

A full description of the significance of lipoproteins can also be found in my article posted on-line at the www.lef.org website at http://www.lef.org/magazine/mag2006/may2006_report_heart_01.htm

Weight and lipoproteins

Tom, an accountant, came into the office eager to know what his 2nd heart scan score showed.

A year ago, Tom's view of himself as a healthy, middle-aged man was shattered when he found out his heart scan score: 1236. Tom had severe coronary plaque with a heart attack risk of 25% per year (without intensive preventive action).

In the way of lipoprotein abnormalities, he had several: low HDL, deficient large HDL, small LDL, high triglycerides, IDL (the after-eating inability to clear dietary fats), and a high blood sugar in the pre-diabetic range. In addition, Tom was hypertensive, with blood pressure so high it even landed him in the emergency room last winter.

In addition to our approach to correct all these patterns, Tom was urged to lose a significant quantity of weight. Starting at 225 lb., at 5 ft 7 inches, Tom was clearly at least 40 lbs over his ideal weight.

I stressed to Tom that the entire spectrum of causes of coronary plaque were weight-related. I likened his patterns to throwing gasoline on a fire: As weight increased, his lipoprotein and other abnormalties flared dramatically.

But each time Tom came back to the office over the ensuing year, he'd gained another 3 to 6 lbs. And each time he had an explanation. "My daughter just got married. I couldn't turn down wedding cake, now could I?" Or, I just survived another tax season. I was working day and night--no time for exercise!" "It's getting too hot to walk anymore."

Well, despite multiple treatments, Tom's repeat heart scan showed a score of 1677, a 35% increase. That's a dangerous rate of growth that virtually guarantees that plaque is building up momentum to "rupture", which results in heart attack.

I therefore stressed to Tom that weight loss was crucial. Control of coronary plaque was simply not going to occur without weight loss to our target. Alternatively, we could add several new prescription medicines and hope that they could achieve the same effect, though at a price (side-effects, expense).

I tell Tom's story to highlight again just how important weight loss can be for a number of lipoprotein abnormalities.

What measures specifically are sensitive to weight? They are:

--HDL cholesterol
--Triglycerides
--Small LDL
--VLDL
--Blood pressure
--Blood sugar and insulin
--C-reactive protein
--LDL

Weight exerts profound influence on these patterns. In Tom and people like him, weight can be a "make it or break it" issue.

If you, like Tom, have any of the above patterns, consider weight loss as a potent tool you can use to gain control of coronary plaque.

Variation in vitamin D requirements


For Track Your Plaque followers, you know we are very concerned about vitamin D blood levels. My prediction is that, in 10 years, vitamin D will be regarded as an important item on the list of coronary artery disease risk factors.

In our experience of trying to stop or reverse heart scan scores, restoration of vitamin D to a blood level of 50 ng/ml appears to have increased our success rate dramatically.

As we've talked about before, on the bell curve of vitamin D dosing in a northern climate, the majority of women require 2000 units per day, men require 3000 units per day to achieve a level of 50 ng. However, there are "outliers" on this bell curve, i.e., people who require much more or much less.

This week, I saw two people who were very instructive cases of extreme requirements on the high end of vitamin D dosing. Both started with unmeasurable blood levels, i.e., essentially zero ng/ml. On 5000 units of vitamin D per day, both raised their blood levels to around 17-18 ng/ml--in the range of severe deficiency (defined as <20 ng/ml). I advised both to increase their oral dose of vitamin D to 8000 units per day.

Notably, both people avoided sunlight and lived in Wisconsin, a terribly sun-deprived locale 10 months a year. Both were also substantially overweight (around 300 lbs each).

The vitamin D issue continues to be endlessly fascinating in all its nuances and twists.

Heart attacks in your own backyard

Two men from my community just died of heart attacks. Both were in their 40s.

What bothers me most about these all too frequent stories is that it is so preventable. You can bet that both had little or no symptoms prior to their deaths. You can also bet that they've had cholesterol panels taken by their doctors.

Followers of the Track Your Plaque program know that these are sure-fire paths to failure. The absence of heart disease symptoms should provide no reassurance whatsoever. High cholesterol, in-between cholesterol, low cholesterol--none are confident indicators in a specific individual.

Stress test? How about the patient I saw today who, until I met him, had been undergoing stress test after stress test, every year--all while the quantity of coronary plaque tripled. False reassurances provided by his cardiologist led him to believe that all was well--while this stack of oily rags was just waiting for the spark to ignite.

Too little time, too much money, too far away--there's a hundred excuses for not getting a heart scan. Or, you've had a heart scan and no one can tell you what to do about it. If you're reading this, however, you've found the most intensive source of information available on how your heart scan can serve as the start of a program of heart attack prevention for a life free of dangers.

It's not that tough. But it won't just go away on its own. I just have to look around me in my own community, watch the local news, talk to friends, and I'll heart about all the people just in my neighborhood who should be learning these lessons. I rant and rave about this but some people need to hear it from a friend, colleague, neighbor, rather than some crazy doctor bucking the standard line.

You, too, should be telling anyone who will listen about how heart disease can be identified and controlled.

Pilot lands safely after heart attack, then dies

That was the disturbing headline on a report from MSNBC, also reported nationally on all the major news networks.

The story goes on:

"A pilot suffering a heart attack made an emergency landing on a highway, saving his three passengers shortly before he died...He landed the single-engine Cessna 185 on Utah 30 near Park Valley and was taken to Bear River Hospital in Tremonton, where he died."

We track these sorts of stories and it's frightening just how common they are. A school bus driver recently had a heart attack while driving 30 children; the bus crashed but no one was hurt. A 52-year old commercial bus driver suffered a heart attack while transporting 49 conference attendees; the bus plunged 400 feet down a ravine. Remarkably, 17 passengers suffered only minor injuries and there were no deaths.

There have even been incidents where the pilot of a jet liner suffered a heart attack in-flight. In 2000, the 53-year old pilot of a Northwest Airlines DC-10 died while in-flight from a heart attack while landing in Minneapolis. The 290 passengers were landed safely by co-pilot.

Most incidents where the driver or pilot has been incapacitated or died resulted in the deaths of only a handful of people. No major catastrophe has yet occured. But--mark my words--it will. These incidents just happen too frequently.

Virtually all of these and similar incidents could have been prevented. If the FAA, for instance, would insist that all pilots have a simple CT heart scan, it would become immediately obvious which pilots should be grounded and who should fly. Similar requirements could easily be applied to persons in charge of the welfare of many people, most notably school bus drivers.

It's not that tough! The FAA currently requires stress testing and cholesterol testing. Well, guess what? Followers of the Track Your Plaque program know that these tests do not effectively identify the person at risk for heart attack in the majority of individuals. Just ask former President Bill Clinton how helpful his stress tests (five in a row!) were. Or how valuable his cholesterol monitoring was--all prior to his emergency bypass surgery.

Large new clinical study launched to study. . .niacin


Oxford University has issued a press release announcing plans for a new clinical trial to raise HDL cholesterol and reduce heart attack risk. 20,000 participants will be enrolled in this substantial effort. The agent? Niacin.

How is that new? Well, this time niacin comes with a new spin.

Dr. Jane Armitage, formerly with the Heart Protection Study that showed that simvastatin (Zocor) reduced heart attack risk regardless of starting LDL, is lead investigator. She hopes to prove that niacin raises HDL cholesterol and thereby reduces heart attack risk. But, this time, niacin will be combined with an inhibitor of prostaglandins that blocks the notorious "flushing" effect of niacin.

The majority of Track Your Plaque participants hoping to control or reverse coronary plaque take niacin. Recall that niacin (vitamin B3)is an extremely effect agent that raises HDL, dramatically reduces small LDL, shifts HDL particles into the effective large fraction, reduces triglycerides and triglyceride-containing particles like IDL and VLDL. Several studies have shown that niacin dramatically reduces heart attack. The HATS Study showed that niacin combined with Zocor yielded an 85-90% reduction in heart attack risk and achieved regression of coronary plaque in many participants.

In our experience, approximately 1 in 20 people will really struggle using niacin. Flushes for these occasional people will be difficult or even intolerable. Should Dr. Armitage's study demonstrate that this new combination agent does provide advantages in minimizing the hot flush effect, that will be a boon for the occasional Track Your Plaque participant who finds conventional niacin intolerable.

But you already have access to niacin, an agent with an impressive track record even without this new study. And you have a reasonably effective prostaglandin inhibitor, as well: aspirin. Good old aspirin is very useful, particularly in the first few months of your niacin initiation to blunt the flush.

Although this study is likely to further popularize niacin and allow its broader use, it's also a method for the drug companies to profit from an agent they know works but is cheap and available.

You don't have to wait. You already have niacin and aspirin available to you.

The dark side of CT heart scans

"I just got a heart scan!" declared Eric to his doctor. He handed the report to him.

"Oh my. Your score is 154." The doctor paused, then looked at Eric with a serious look on his face. "If we're going to understand whether or not you're in danger, you'll need a heart catheterization."


I've seen this happen countless times. How can I say this diplomatically? THIS IS WRONG!! In my view, it's absolutely criminal for this to happen. Physician ignorance, profiteering, whatever--it is wrong.

There's very few reasons why someone who has no symptoms should go directly to the cath lab for a procedure. (A rare exception might be an exceptional quantity of plaque in the left mainstem artery, e.g., >100. This is highly unusual.)

Even a nuclear stress test (e.g., thallium) at this level of scoring is only 10-15% likely to be abnormal. That means 85-90% likelihood of being normal. There's rare reasons to perform a heart catheterization in a person with no symptoms and an entirely normal stress test. The vast majority of people like Eric do not need a heart catheterization to discern risk.

If Eric's doctor had been up-to-date on the published literature on the prognostic value of heart scans, he could have advised Eric what the risks were--without a catheterization. Many doctors simply don't want to be bothered. Or, they opt for the more profitable method--a hospital procedure.

Always discuss your heart scan with your doctor--but be armed with information in case your doctor is uninformed or unscrupulous. Unfortunately, that's not uncommon. The Track Your Plaque program is your advocate, a source for unbiased information.

The dirty little secret about aneurysms

Jake had an abdominal aneurysm identified--by accident.

While getting a CT scan of his abdomen for unexplained abdominal pain, a 4.4 cm aneurysm was discovered. Jake's abdominal pain eventually passed without explanation, but he was left with this aneurysm.

Jake's primary care doctor referred him to a surgeon. "It's too small to require surgery right now. Wait a few years and it'll probably get bigger. When it gets to around 5.5 cm, that'll be the time to operate. Let's schedule an abdominal ultrasound or CT scan every 6 months."

Jake then got himself a heart scan. His high score of 879 then led him to my office. Lipoprotein testing, a stress test, correction of his lipoprotein patterns, changes in lifestyle followed. One year later, Jake's heart scan score was unchanged.

How about his abdominal aneurysm? 4.2 cm--a modest quantity of regression. When Jake's surgeon learned of the change, he just shrugged. "Okay, we'll just watch it from here."

Shockingly, the conversation surrounding aneurysms is just like the one Jake received: Let's just watch it grow until you need surgery.

If you've every seen anyone have abdominal aneurysm surgery, you know it is an awful, painful, barbaric process with high risk for major complications like kidney failure and loss of the legs. Waiting for an aneurysm to grow is a lousy solution. Surgeons point out that, although surgery is imperfect, it's better than the alternative: rupture, which is catastrophic with a 50% chance of dying.

But what about stopping the growth of the aneurysm? Or even reversing, or shrinking, it?

Surgeons say it can't be done. Yet we've done it--many times. And it's not that difficult.

The steps to take are very similar to that in the Track Your Plaque program for coronary plaque regression, with a few different strategies. Suppression of inflammation, for instance, plays a more important role and blood pressure must be abolutely normal, even during exercise.

More to come on this important topic in the future, including an upcoming Special Report on the www.cureality.com membership website.

Heart scan scores dropping like stones!!

I saw two instances of dramatic coronary plaque regression today.

John, a 53-years old mechanical lift operator, dropped his heart scan score from 479 to 323--a 32% regression of coronary plaque volume!

Eric, a 50-year consulting engineer, dropped his heart scan score from 668 to 580--a 13% reduction.

Both men did nothing special beyond the principles advocated in the Track Your Plaque program. Recall that, without preventive efforts, your heart scan score is expected to increase by 30% per year. Both men are well on their way to freedom from risk of coronary "events".

Two less people to feed the revenue-hungry hospital procedure system! We need many more like them.

Is there something fishy about fish oil?

To be sure, there's plenty of misinformation out there about fish oil. Take a look at the swill that passes for health information on Woman's Day: On Call with Dr. Sandy: Fish Oil and Mercury:



Reader Question: My doctor recommended that I take a fish oil supplement, but I'm concerned about mercury. Is there any way to tell which brands are lowest in mercury content?



On Call Response: When it comes to OTC supplements, the answer is no. Though most fish oil supplements sold by major brands are probably safe, there's really no way to tell what's in the bottle or how much mercury it might contain.




Perhaps Dr. Sandy should read the many independent analyses performed on nutritional supplement fish oil, including those at Consumer Lab and Consumer Report before she offers her blind criticisms.

Lovaza vs fish oil supplements?

Lovaza is the FDA-approved form of fish oil that is available only by prescription. It contains 842 mg of the omega-3 fatty acids, EPA and DHA, per capsule.

The FDA application for Lovaza is viewable here on the FDA website. Interestingly, while there is plenty of the usual regulatory gobbledy-gook about toxicology, dose escalation, and efficacy in the extensive documentation, there is little said about the issue of contamination.

In other words, critics of nutritional supplement fish oil harp on the possibility of contamination with mercury and pesticide residues, like dioxin and PCBs (polychlorinated biphenyls). Yet there is virtually nothing about these same issues in the FDA application for Lovaza.

Let's take a look at a sample over-the-counter fish oil product. Our friends at PharmaNutrients (a new Track Your Plaque partner for nutritional supplements) have a fish oil product called PharmaNutrients" Cardio. Here's an independent analysis of the Cardio product (per 1000 mg fish oil capsule):

EPA content: 566.1 mg
DHA content: 216.6 mg
(Total EPA + DHA 782.7 mg)

Cardio passed all tests for peroxides, PCBs, dioxin, furans, dioxin-like PCBs, and heavy metals (arsenic, cadmium, lead, mercury) using criteria at least 60% more stringent than European Commission (EC) standards (EC standard <2 picograms/gm for dioxins and furans, PharmaNutrients <1 picograms/gm; EC standard <10 picograms/gm for dioxin-like PCBs, PharmaNutrients <3 picograms/gm). PCBs levels in particular are less than 0.009 ppm, 90% below the industry-wide purity standard of 0.09 ppm. Likewise, mercury is >90% lower than European Commission standards.

In other words, this over-the-counter "pharmaceutical grade" fish oil has virtually nothing but omega-3 fatty acids.

Interestingly, the PharmaNutrients fish oil capsule also contains the third omega-3 fatty acid, docosapentaenoic acid (DPA), a neglected form that some authorities have proposed has superior cardiovascular protective properties over eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). If DPA is included in the analysis, PharmaNutrient's Cardio contains a total of 900 mg omega-3 fatty acids per capsule.

At some point, I'd like to see a head-to-head comparison not just on purity grounds, since I am convinced that high-quality products like Cardio can match or exceed the purity of prescription fish oil, but on efficacy in raising omega-3 blood levels, the omega-3 index. (The omega-3 index is a predictor of heart attack and sudden cardiac death--the higher, the better.) My prediction: High-quality fish oil supplements will match or exceed prescription fish oil.

More on blood sugar

Take any of the following foods:

One chicken breast
Quarter-pound ground beef
6 oz salmon steak
½ cup raw almonds
3 eggs scrambled in olive oil

How much is blood sugar increased by any item in the above list?

If you said virtually zero, you’re correct. Eat any of these foods, regardless of portion size, and blood sugar won’t change substantially. If you started with a blood sugar of, say, 90 mg/dl, 1-2 hours later it would be 90 mg/dl. It might go up or even down a few milligrams, but for all practical purposes it remains substantially unchanged.

How much is blood sugar increased by the foods in this list:

2 slices multigrain bread
1 whole wheat bagel
4 oz high-fiber breakfast cereal
2 whole grain pancakes, 2 oz maple syrup

The foods in this list are a different story from the first. Depending on your body weight, exercise habits, and other factors, a typical blood sugar response in an otherwise healthy non-diabetic person would be 120 mg/dl to 160 mg/dl. In someone with diabetes, it could easily exceed 200 mg/dl.

That isn’t good. Large blood sugar excursions to 140 mg/dl have been clearly associated with greater risk for heart attack, progression to diabetes, inflammatory responses, and other adverse health effects. In fact, blood sugars as low as 100 mg/dl after eating have been associated with increased cardiovascular risk.

Then why are the USDA, American Heart Association, the American Dietetic Association, and the American Diabetes Association telling us to eat more of the foods that shoot blood sugar up to such high levels? “Eat more healthy whole grains”?

To see how much the issue of exaggerated blood sugars after eating applies to you, a simple blood sugar check 1-2 hours after eating can show you. Either your doctor can have the test drawn or you can purchase your own inexpensive glucose meter (e.g., Walmart, Wagreens).

My prediction: You will be very surprised at blood sugar responses after common foods, including “healthy whole grains.” And, by the way, keeping blood sugar excursions to a minimum will facilitate weight loss.

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

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

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

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

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

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

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

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

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

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

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

Food sources of vitamin K2: Reprint

For some reason, my December, 2007, Heart Scan Blog post, Food sources of vitamin K2, has been receiving a lot of traffic.

I therefore reprint the vitamin K2 post below.





Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

The ideal source of K2 is natto, the unpalatable, gooey, slimy mass of fermented soybeans that Japanese eat and has been held responsible for substantial decreases in osteoporosis and bone fractures of aging. Natto has an ammonia-like bouquet, in addition to its phlegmy consistency that makes it virtually inedible to anyone but native Japanese.

I say that the conversation on vitamin K2 is emerging because of a number of uncertainties: What form of vitamin K2 is best (so-called MK-4 vs. MK7 vs. MK-9, all of which vary in structure and duration of action in human blood)? What dose is required for bone benefits vs. other benefits outside of bone health? Why would humans have developed a need for a nutrient that is created through fermentation with only small quantities in meats and other non-fermented foods?

Much of the developing research on vit K2 is coming from the laboratories of Drs. Vermeer, Geleijnse, and Schurgers at the University of Maastricht in the Netherlands, along with several laboratories in Japan, the champions of K2.

MK-7 and MK-8,9,10 come from bacterial fermentation, whether in natto, cheese, or in your intestinal tract; MK-4 is naturally synthesized by animals from vitamin K1. While natto is the richest source of the MK-7 form, egg yolks and fermented cheeses are the richest sources of the MK-4 form.

Chicken contains about 8 mcg MK-4 per 3 1/2 oz serving; beef contains about 1 mcg. Egg yolks contain 31 mcg MK-4 per 3 1/2 oz serving (app. 6 raw yolks). Hard cheeses contain about 5 mcg MK-4 per 3 1/2 oz serving, about 70 mcg of MK-8,9; soft cheeses contain about 30% less. Natto contains about 1000 mcg of MK-7, 84 mcg MK-8, and no MK-4 per 3 1/2 oz serving.















Feta cheese

Thanks to the research efforts of the Dutch and Japanese groups, several phenomena surrounding vitamin K2 are clear, even well-established fact:

--Vitamin K2 supplementation (via frequent natto consumption or pharmaceutical doses of K2) substantially improves bone health. While K2 by itself exerts significant bone density/strength increasing properties in dozens of studies, when combined with other bone health-promoting agents (e.g., vitamin D3, prescription drugs like Fosamax and calcitonin), an exaggerated synergy of bone health-promoting effects develop.



--The MK-4 form of vitamin K2 is short-lived, lasting only 3-4 hours in the body. The MK-7 form, in contrast, the form in natto, lasts several days. MK-7 and MK-8-10 are extremely well absorbed, virtually complete.

--Bone health benefits have been shown for both the MK-7 and MK-4 forms.

--Coumadin (warfarin) blocks all forms of vitamin K.





Interestingly, farm-raised meats and eggs do not differ from factory farm-raised foods in K2 content. (But please do not regard this as an endorsement of factory farm foods.)

Another interesting fact: Since mammals synthesize a small quantity of Vit K2 forms from vitamin K1, then eating lots of green vegetables should provide substrate for some quantity of K2 conversion. However, work by Schurgers et al have shown that K1 absorption is poor, no more than 10%, but increases significantly when vegetables are eaten in the presence of oils. (Thus arguing that oils are meant to be part of the human diet. Does your olive oil or oil-based salad dressing represent fulfillment of some subconscious biologic imperative?)

If we believe the data of the Rotterdam Heart Study, then a threshold of 32.7 micrograms of K2 from cheese yields the reduction in cardiovascular events and aortic calcification.

It's all very, very interesting. My prediction is that abnormal (pathologic) calcium deposition will prove to be a basic process that parallels atherosclerotic plaque growth, and that manipulation of phenomena that impact on calcium depostion also impact on atherosclerotic plaque growth. Vitamins D3 and K2 provide potential potent means of at least partially normalizing these processes.

As the data matures, I am going to enjoy my gouda, Emmenthaler, Gruyere, and feta cheeses, along with a few egg yolks. I'm going to be certain to include healthy oils like olive and canola with my vegetables.

Family lessons

Lou was recovering from his 3rd bypass operation. This third go-round left him weaker, slower, less quick on the rebound. In fact, he was lucky to have survived.

At 71 years old, Lou went a good 15 years since his second bypass, another 10 years prior to his first bypass at age 46.

In the days immediately following Lou's bypass, I had a chance to talk to his son, who stayed at his Dad's bedside while Lou struggled through post-op recovery.

"Did your Dad tell you about why this has happened, what caused his heart disease?" I asked.

"Sort of. He just said I should get checked," Lou's son, Aaron, replied.

"Did he mention the lipoprotein(a) pattern he has?"

"No. He never mentioned anything like that. He just said to get checked."

That's how it gets played out more often than not: Mom or Dad has a heart attack, stents, or (3rd) bypass, the children are told to get checked. Getting "checked" assumes that the doctor knows what to check for.

In Lou's case, the reason why he was in the hospital getting his 3rd (and final) bypass was lipoprotein(a), along with genetically-determined small LDL particles, low HDL, a postprandial (after-eating) disorder, hypertension, and borderline diabetes, not to mention vitamin D deficiency, omega-3 fatty acid deficiency, and marginal thyroid function. (Lou, a retired city employee, had showed only marginal interest in correcting these patterns. While he accepted medications, he proved unwilling to engage in the diet and nutritional supplement strategies required to correct his patterns.)

So Lou's 3rd bypass operation provided a moment of reflection for Aaron to ask: "Could I share the fate of my Dad?" With Lou's combination of genetic patterns, there was at least a 75% likelihood that he did. Sadly, going to his doctor would likely yield little more than a cholesterol panel, a question about smoking, and a prescription for Lipitor.

Just getting "checked" would be, more than likely, a recipe for disaster for Aaron: heart disease in his 40s or 50s. That's why you need to take control over this sad state of affairs and ask--no, insist--that an effort be made to determine whether you might share your parents' fate.

Look like Jimmy Stewart


"This diet works great," Don declared. "But I think I've lost too much weight."

At 67 years old and 5 ft. 11 inches, Don began the program weighing 228 lbs (BMI 31.9). Because of high triglycerides, high blood sugar, high c-reactive protein, and excessive small LDL, I instructed Don to eliminate all wheat products from his diet, along with cornstarch and sweets. His intake of lean meats, eggs, vegetables, oils, raw nuts, etc. was unlimited.

Don now weighed 194 lbs, down 34 lbs over 6 months (BMI 27.1). Triglycerides, blood sugar, blood pressure, and well-being had improved dramatically; small LDL, however, had dropped only 30%--still room for improvement.

"My friends say I'm too skinny. They ask if I have cancer!"

I've heard this many times: Someone loses weight in a relatively short period of time and friends and family tell you you're too skinny. "It must be cancer. Nobody loses weight like that."

Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man. But Americans have put on so much weight that the prevailing view of what constitutes "normal" weight has been revised upward. Normal is closer to what we see in old movies from the 1940s and '50s with people like Jimmy Stewart and Donna Reed. That's what we are supposed to look like.

So Don actually remains mildly overweight but is judged as "too skinny," or even cancer-ridden, by friends and family.

Ignore such comments. As you lose pounds and approach a truly desirable weight, realize that you are returning to the normal state, not the vision of "normal" now held by most Americans.

Getting vitamin D right

Vitamin D is, without a doubt, the most incredible "vitamin"/prohormone/neurosteroid I have ever encountered. Frankly, I don't know how we got anything accomplished in health pre-D.

Unfortunately, people I meet rarely take their vitamin D in a way that accomplishes full restoration of vitamin D blood levels. It really isn't that tough.

Here's a list of common tripping points with vitamin D:

"I take vitamin D: 1000 units a day."
This is probably the most common mistake I see: Taking a dose that is unlikely to yield a desirable blood level. (We use 60-70 ng/ml of 25-hydroxy vitamin D as our target.) Most men and women require 6000 units per day to achieve this level. There is substantial individual variation, however, with an occasional person needing much more, a rare person requiring as little as 1000 units.


"I bought some vitamin D on sale. They were white tablets."
Time and again, patients in my office who initially have had successful vitamin D replacement, despite being reminded that only oil-based forms should be taken, switch to tablets. While they initially showed a 25-hydroxy vitamin D blood level, for instance, of 67 ng/ml on 8000 units per day with an oil-based capsule, they switch to a tablet form and the next blood level is 25 ng/ml. In other words, tablets are very poorly or erratically absorbed.

I have had people use tablets successfully, however, by taking their vitamin D tablets with a teaspoon of oil, e.g., olive oil. Oil is necessary for full absorption.


"I'm going to Florida. I'll stop my vitamin D because I'm going to lay in the sun."
Wrong. 90% of adults over 40 years old have lost the majority of their ability to activate vitamin D in the skin. A typical response might be an increase in blood level from 25 to 35 ng/ml--a 10 ng increase with a dark brown tan.

There is an occasional person who, with sun exposure, increases blood levels substantially. This can occur in both fair-skinned and dark-skinned people, though I've never seen it happen in an African-American person. The occasional person who maintains the ability to convert vitamin D with sun exposure, or young people, should seasonally adjust their vitamin D dose, e.g., 6000 units winter, 3000 units summer, or some other regimen that maintains desirable blood levels. You can see that monitoring blood levels (we check levels every 6 months for the first 2 years) is crucial: You cannot know what your vitamin D needs are unless you assess 25-hydroxy vitamin D levels.


"I drink plenty of milk. I don't think I need to take vitamin D."
Oh, boy. This is so wrong on so many levels.

First of all, no adult should be drinking plenty of cow's milk. (A discussion for another day.) Second of all, cow's milk averages 70 units of vitamin D, often the D2 form (ergocalciferol), per 8 oz. Even if the FDA-mandated 100 units per day were present, an average adult dose of 6000 units would require 60 glasses of milk per day. Can you say "diarrhea"?

Likewise, other food sources of vitamin D, such as fish (300-400 units per serving) and egg yolks (20 units per yolk), are inadequate. This makes sense: Humans are not meant to obtain vitamin D from food, but from sun exposure over a large body surface area. And this is a phenomenon that is meant to occur only in the youthful, ensuring that nature takes its course and us older folks get old and make way for the young (i.e., unless we intervene by taking vitamin D supplements).


"My doctor said that my vitamin D blood level was fine. It was 32 ng/ml."

Let's face it: By necessity, your overworked primary care physician, who manages gout, hip arthritis, migraine headaches, stomach aches, prostate enlargement, H1N1, depression, etc., is an amateur at nearly everything, expert in nothing. Nobody can do it all and get it right. Likewise vitamin D. The uncertain primary care physician will simply follow the dictates of the laboratory form that specifies "30-100 ng/ml" as the "normal" or "reference range." Unfortunately, the laboratory often quotes population distributions of a lab measure, not an ideal or desirable level.

To illustrate the folly of population distributions of a measure, imagine you and I want to know what women weigh. We go to a local mall and weigh several thousand women. We tally up the results and find that women weigh 172 lbs +/- 25 lbs (the mean +/- 2 standard deviations). (That's true, by the way.) Is that desirable? Of course it isn't. Population average or population distribution does not necessarily mean ideal or desirable.


"My husband's doctor said he should take 4000 units per day. So I just take the same dose."
That would be fine if all adults required the same dose. However, individual needs can vary enormously. A dose that is grossly insufficient for one person may be excessive for another. Once again, vitamin D dose needs can be individualized by assessing 25-hydroxy vitamin levels in the blood.


"I don't need to take vitamin D. I already take fish oil."
I suspect this mistaken belief occurs either because people confuse fish oil with cod liver oil, which does contain some vitamin D. (Cod liver oil is not the best source of vitamin D, mostly because of the vitamin A content; also a discussion for another time), or because they've heard that eating fish provides vitamin D. However, fish oil capsules do not contain vitamin D unless it is added, in which case it should be prominently and explicitly stated on the label.


"I don't have to take vitamin D. It's summer."

For most people I know, if it's a bright, sunny July day, where are they likely to be? In an office, store, or home--NOT lying in the sun with a large body surface area exposed. Also, most people expose no more than 5-10% of surface area in public. I doubt you cut the grass in a bathing suit. Because of modern indoor lifestyles and fashion, the majority of adults need vitamin D supplementation year-round.


I advise everyone that gelcap vitamin D is preferable. Some, though not all, liquid drop forms have also worked. Take a dose that yields desirable blood levels. And blood levels of 25-hydroxy vitamin D are ideally checked every 6 months: in summer and in winter to provide feedback on how much sun activation of D you obtain.

If your doctor is unwilling or unable to perform vitamin D testing, fingerstick vitamin D test kits can be obtained from Track Your Plaque.

Jimmy Moore's thyroid adventure

My friend, Jimmy Moore of Living La Vida Low Carb, describes his thyroid experience here.

As Jimmy points out, he was looking for a way to jump-start a 50-lb weight loss. In my experience, low thyroid hormone levels ("hypothyroidism") are an exceptionally common cause for weight gain. Correcting even marginal hypothyroidism can facilitate weight loss, often resulting in 10 or more pounds of weight loss within the first month.

Unfortunately, Jimmy's thyroid hormone panel proved normal: TSH 1.3, thyroid hormones free T3 and free T4 in the mid- to upper-half of the reference range.

I say "unfortunately" because it is really an easy, inexpensive, and benign solution for losing weight. (I don't, of course, wish that Jimmy or anyone else develops a thyroid condition. But it really can provide gratifying weight loss results when thyroid function is low.) Jimmy might consider taking his oral temperature first thing in the morning as another means of assessing the adequacy of thyroid function.

Perhaps you will be luckier than Jimmy and have thyroid dysfunction that can be corrected and jump-start your weight loss program. Fingerstick thyroid test kits like the one Jimmy used are available here from Track Your Plaque.
