Bosom buddies

9. October 2010 William Davis (22)
Male breast reduction surgery is a booming business. While most industries are in a downward tailspin, breast reduction surgery in men is growing at double-digit rates.

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

Exercise programs to reduce male breast size.

Liposuction--Not just for the belly!

Plastic surgery

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

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


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

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

So where does the excess estrogen come from?

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

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

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

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

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

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

Don't be a dipstick

3. October 2010 William Davis (32)
If I want to know how much oil is in my car's engine, I check the dipstick.

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

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

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

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

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

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

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

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

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

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

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

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

The ultimate insurance company cost savings

29. September 2010 William Davis (48)
I had a very disturbing conversation with a physician who is employed by an insurance company last week.

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

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

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

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

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

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

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

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

Salvation from halogenation

24. September 2010 William Davis (26)
Iodine is a halogen.

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

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

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

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

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

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

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

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

Lipitor-ologist

22. September 2010 William Davis (30)
One of the things I do in practice is consult in complex hyperlipidemias, the collection of lipoprotein disorders that usually, but not always, lead to atherosclerosis.

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

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

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

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

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

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

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

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

Robb Wolf's new Paleo Solution

20. September 2010 William Davis (16)
The Paleo Solution: The Original Human Diet


The Paleo Solution: The Original Human Diet

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

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

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

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

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

Human foie gras

18. September 2010 William Davis (10)
If you want to make foie gras, you feed ducks and geese copious quantities of grains, such as corn and wheat.

The carbohydrate-rich diet causes fat deposition in the liver via processes such as de novo lipogenesis, the conversion of carbohydrates to triglycerides. Ducks and geese are particularly good at this, since they store plentiful fats in the liver to draw from during sustained periods of not eating during annual migration.

Modern humans are trying awfully hard to create their own version of foie gras-yielding livers. While nobody is shoving a tube down our gullets, the modern lifestyle of grotesque carbohydrate overconsumption, like soft drinks, chips, pretzels, crackers, and--yes--"healthy whole grains" causes fat accumulation in the human liver.

Over the past few years, there has been an explosion of non-alcoholic fatty liver disease and non-alcoholic steatosis, two forms of liver disease that result from excess fat deposition. The situation gets so bad in some people that it progresses to cirrhosis, i.e., a hard, poorly-functioning liver that paints a very ugly health picture. The end-result is identical to that experienced by longstanding alcoholics.



While Hannibal Lecter might celebrate the proliferation of human fatty livers with a glass of claret, fatty liver disease is an entirely preventable condition. All it requires is not eating the foods that create it in the first place.

Let go of my love handles

14. September 2010 William Davis (44)
When is fat not just fat?

When it's visceral fat. Visceral fat is the fat that infiltrates the intestinal lining, the liver, kidneys, even your heart. It's the stuff of love handles, the flabby fat that hangs over your belt, or what I call "wheat belly."

Unlike visceral fat, the fat in your thighs or bottom is metabolically quiescent. Thigh and bottom fat may prevent you from fitting into your "skinny jeans," but its mainly a passive repository for excess calories.

Visceral fat, on the other hand, is metabolically active. It produces large quantities of inflammatory signals ("cytokines"), such as various interleukins, leptin, and tumor necrosis factor, that can trigger inflammatory responses in other parts of the body. Visceral fat also oddly fails to produce the protective cytokine, adiponectin, that protects us from diabetes, cancer, and heart disease.

Visceral fat also allows free fatty acids to leave and enter fat cells, resulting in a flood of fatty acids and triglycerides (= 3 fatty acids on a glycerol "backbone") in the bloodstream. This worsens insulin responses ("insulin resistance") and contributes to fatty liver. The situation is worsened when the very powerful process of de novo lipogenesis is triggered, the liver's conversion of sugar to triglycerides.

Visceral fat is also itself inflamed. Biopsies of visceral fat show plenty of inflammatory white blood cells (macrophages) infiltrating its structure.

So what causes visceral fat? Anything that triggers abnormal increases in blood glucose, followed by insulin, will cause visceral fat to grow.

It follows logically that foods that increase blood glucose the most will thereby trigger the greatest increase in visceral fat. Eggs don't lead to visceral fat, nor do salmon, olive oil, beef, broccoli, or almonds. But wheat, cornstarch, potato starch, rice starch, tapioca starch, and sugars will all trigger glucose-insulin that leads to visceral fat accumulation.

Fructose is also an extravagant trigger of visceral fat. Fructose is found in sucrose (50% fructose), high-fructose corn syrup, agave syrup, maple syrup, and honey.

Increased visceral fat can be suggested by increased waist circumference. The inflammatory hotbed created by excess visceral fat has therefore been associated with increased likelihood of heart attack, cardiovascular mortality, diabetes, cancer, and total mortality.

So I'm not so worried that you can't squeeze your bottom into your size 8 jeans. I am worried, however, when you need to let your belt out a notch . . . or two or three.

Surviving a widow maker

11. September 2010 William Davis (19)
Gwen came to me 5 years ago. In her late 60s, she'd been having feelings of chest pressure for the past 4 weeks with small physical efforts, such as climbing a flight of stairs or lifting her grandchildren.

She sat in my office, heaving small sobs, accompanied by her daughter.

Gwen had already undergone a heart catheterization at a hospital near home by a cardiologist who I knew to be honest and competent. She'd been told that she had a 90% stenosis ("blockage") of her proximal left anterior descending (LAD) coronary artery. He called it a "widow maker," since closure of the artery at this point can be fatal within minutes. He advised bypass surgery as soon as possible. Though a stent could be placed at this location, he felt that its proximity to the left main stem (i.e., the "trunk" that divides into the LAD and circumflex arteries) might be jeopardized by expanding a stent in this bulky plaque, what I felt was a reasonable concern.

I reviewed the images that she brought with her. Yes, indeed: a widow maker. The portion of the left ventricle (heart muscle) fed by the LAD was also impaired ("hypokinetic"), reflecting reduced flow through the artery.

I advised Gwen that her first cardiologist's advice was sound: This was a potentially dangerous and severe condition. Either a bypass or stent should be performed near-future, the less delay the better.

But Gwen and her daughter would have no talk of any more procedures. She'd come to me because she heard about the (then rudimentary) effort I'd been making at reversing coronary plaque. "I admire your commitment, Gwen, but I am concerned that there may not be sufficient time to implement a program of prevention or reversal. Prevention is very powerful, but very slow. When symptoms like yours are active, also, it can mean that we won't have full control over the plaque causing the symptoms. This risks closure of the vessel, since flow characteristics in the plaque are abnormal. I think that you should go through a stent or bypass. We can then start your prevention/reversal program once we know you're safe."

Gwen would still have none of it. I asked her to return in a few days after thinking it over. In the meantime, we drew her lipoprotein blood samples while she added fish oil, l-arginine (back then I used a lot of l-arginine for its endothelial health effects), and began the Track Your Plaque diet a la 2004. This was in addition to the aspirin, beta blocker, and statin prescribed by the first cardiologist.

Several days later, Gwen and her daughter returned, as committed as ever to not having a procedure and proceeding with our prevention/reversal efforts.

So off we went. I was nervous about Gwen's safety, but she had clearly made her mind made up. Gwen's lipoprotein analysis revealed a severe small LDL pattern along with markers for prediabetes (high insulin, high blood glucose, hypertension, along with the loose tummy of visceral fat). So I counseled her intensively in diet and added niacin.

Within 2 weeks, Gwen no longer had chest pain. Whether this was due to her efforts or to some resolution of an intraplaque phenomenon (e.g., resorption of internal plaque hemorrhage), I don't know. But her symptoms did not return.

As the program evolved, we added the new strategies along the way--vitamin D supplementation; elimination of all wheat along with other changes in diet; iodine and thyroid normalization; as well as discontinuing l-arginine after the initial two years. She also got rid of the statin drug after losing around 20 lbs on the diet.

It's now been six years with her "widow maker" and Gwen has been fine: no recurrence of her symptoms, all stress tests performed have been normal, reflecting normal blood flow in her coronary arteries.

Should ALL people with symptomatic widow makers undergo such an effort and avoid procedures? No, not yet. Prevention and reversal efforts are indeed powerful, but slow. Some people just may not have sufficient time to accomplish what Gwen did. The fact that Gwen showed evidence for reduced flow in the LAD worried me in particular. There is no question that mortality benefits for stenting or bypass of this location are not as large as previously thought (see here, for instance), but each case needs to be viewed individually, factoring in flow characteristics in the artery, appearance of "stability" or "instability" of the plaque itself, not to mention commitment of the person.

But it can be done.

Fred Hahn's Slow Burn

8. September 2010 William Davis (166)
I just had a workout with personal trainer and fitness expert, Fred Hahn. After a workout that quickly taught me that I had a lot to learn about exercise and strength training, Fred and I had a nice low-carbohydrate dinner at a Manhattan restaurant and shared ideas.

Fred is coauthor of Slow Burn Fitness Revolution: The slow motion exercise that will change your body in 30 minutes a week, written in collaboration with the Drs. Eades, Michael and Mary Dan. Fred also blogs here.

I had heard about Fred's "slow-burn" concept in past, but made little of it. I then met Fred on Jimmy Moore's low-carb cruise this past year, where I gave a talk on how carbohydrate-reduced diets reduce small LDL particles. Fred provided a group demonstration on his slow-burn techniques. I watched the demonstration, even tried it a few times back home in the gym, but never really applied them, losing patience most of the time and just going back to my usual routine.

Well, Fred showed me today how to do his slow-burn. In a nutshell, it is the slow, methodical use of weight resistance until the muscle is exhausted. It involves slow movement--e.g., 5 seconds for a lat pulldown from top to bottom--repeated until exhaustion using a weight that allows, perhaps, 6 repetitions over a 60-second effort.

I've been strength training since I was a teenager. I've seen lots of bad training techniques, injuries, and hocum when it comes to how to use resistance training techniques. But I believe that Fred Hahn's slow-burn technique really provides something unique that I hadn't experienced before.

For one, the burn is nothing like I've felt before. Two, there appears to be nearly zero risk for injury, since the usual momentum-driven, herky-jerky motion often employed with weight machines is entirely gone. Three, if what Fred is seeing is true--enhanced visceral (abdominal) fat loss, reduced blood glucose, increased HDL, decreased LDL/total cholesterol--then there's something really interesting going on here.

I also discovered that Fred is no ordinary personal trainer. He has insights into metabolism that I found truly impressive. After all, he's been hanging around with Mike Eades, who's a pretty sharp guy. What Mike Eades is to metabolic insights is what Fred Hahn is to exercise physiology.

I'm going to take Fred's slow burn training insights home with me. I'll let you know how it goes. Some aspects I'd like to explore: Will strength, muscle mass, and blood sugar responses change?



Fred Hahn's latest book, adapting slow burn techniques for kids.

Why haven't you heard about lipoprotein(a)?

1. July 2010 William Davis (26)
Lipoprotein(a), or Lp(a), is the combined product of a low-density lipoprotein (LDL) particle joined with the liver-produced protein, apoprotein(a).

Apoprotein(a)'s characteristics are genetically-determined: If your Mom gave the gene to you, you will have the same type of apoprotein(a) as she did. You will also share her risk for heart disease and stroke.

When apoprotein(a) joins with LDL, the combined Lp(a) particle is among the most aggressive known causes for coronary and carotid plaque. If apoprotein(a) joins with a small LDL, the Lp(a) particle that results is especially aggressive. This is the pattern I see, for instance, in people who have heart attacks or have high heart scan scores in their 40s or 50s.

Lp(a) is not rare. Estimates of incidence vary from population to population. In the population I see, who often come to me because they have positive heart scan scores or existing coronary disease (in other words, a "skewed" or "selected" population), approximately 30% express substantial blood levels of Lp(a).

Then why haven't you heard about Lp(a)? If it is an aggressive, perhaps the MOST aggressive known cause for heart disease and stroke, why isn't Lp(a)featured in news reports, Oprah, or The Health Channel?

Easy: Because the treatments are nutritional and inexpensive.

The expression of Lp(a), despite being a genetically-programmed characteristic, can be modified; it can be reduced. In fact, of the five people who have reduced their coronary calcium (heart scan) score the most in the Track Your Plaque program, four have Lp(a). While sometimes difficult to gain control over, people with Lp(a) represent some of the biggest success stories in the Track Your Plaque program.

Treatments for Lp(a) include (in order of my current preference):

1) High-dose fish oil--We currently use 6000 mg EPA + DHA per day
2) Niacin
3) DHEA
4) Thyroid normalization--especially T3

Hormonal strategies beyond DHEA can exert a small Lp(a)-reducing effect: testosterone for men, estrogens (human, no horse!) for women.

In other words, there is no high-ticket pharmaceutical treatment for Lp(a). All the treatments are either nutritional, like high-dose fish oil, or low-cost generic drugs, like liothyronine (T3) or Armour thyroid.

That is the sad state of affairs in healthcare today: If there is no money to be made by the pharmaceutical industry, then there are no sexy sales representatives to promote a new drug to the gullible practicing physician. Because most education for physicians is provided by the drug industry today, no drug marketing means no awareness of this aggressive cause for heart disease and stroke called Lp(a). (When a drug manufacturer finally releases a prescription agent effective for reducing Lp(a), such as eprotirome, then you'll see TV ads, magazine stories, and TV talk show discussions about the importance of Lp(a). That's how the world works.)

Now you know better.

How to have a heart attack in 10 easy steps

29. June 2010 William Davis (48)
If you would like to plan a heart attack in your future, here are some easy-to-follow steps to get you there in just a few short months or years:


1) Follow a low-fat diet.

2) Replace fat calories with "healthy whole grains" like whole wheat bread.

3) Eat "heart healthy" foods like heart healthy yogurt and breakfast cereals from the grocery store.

4) Use cholesterol-reducing plant sterols.

5) Take a multivitamin to obtain all the "necessary" nutrients.

6) Take the advice of your doctor who declares your heart "in great shape" based on your cholesterol values.

7) Take the advice of your cardiologist who declares your heart "like that of a 30-year old" based on a stress test.

8) Take a statin drug to reduce LDL and c-reactive protein while maintaining your low-fat diet.

9) Neglect sun exposure and vitamin D restoration.

10) Limit your salt intake while not supplementing iodine.



There you have it: An easy, 10-step process to do your part to help your local hospital add on its next $40 million heart care center.

If you would instead like to prevent a heart attack in your future, then you should consider not doing any of the above.

Kick inflammation in the butt

25. June 2010 William Davis (0)
C-reactive protein, or CRP, is a protein produced by the liver in response to inflammatory signals its receives. Thus, CRP has emerged as a popular measure to gauge the underlying inflammatory status of your body. Higher CRP levels (e.g., 3.0 mg/L or greater) are associated with increased risk of heart attack and other cardiovascular events.

The drug cartel have jumped on this with the assistance of Harvard cardiologist, Dr. Paul Ridker. Most physicians now regard increased CRP as a mandate to institute statin therapy, preferably at high doses based on such studies as The JUPITER Trial, in which rosuvastatin (Crestor), 20 mg per day, reduced CRP 37%.

I see this differently. Two strategies drop CRP dramatically, nearly to zero with rare exception: Vitamin D restoration and wheat elimination. Not 37%, but something close to 100%.

Yes, I know it sounds wacky. But it works almost without fail, provided the rest of your life is conducted in reasonably healthy fashion, i.e., you don't live on Coca Cola, weigh 80 lbs over ideal weight, and smoke.

How can something so easily reduced like CRP mean you "need" medication? Easy: Increased CRP means there are fundamental deficiencies and/or inflammation provoking foods in your diet. Correct neither and there is an apparent benefit to taking a statin drug.

Why not just correct the underlying causes?

Life without Lipitor

25. June 2010 William Davis (17)
One of the most common reasons people come to my office is to correct high cholesterol values without Lipitor. (Substitute "Lipitor" with Crestor, simvastatin, Vytorin, or any of the other cholesterol drugs; it's much the same.)

In the world of conventional healthcare, in which you are instructed to follow a diet that increases risk for heart disease and not advised to correct nutrient deficiencies like vitamin D and omega-3 fatty acids, then a drug like Lipitor may indeed provide benefit.

But when you are provided genuinely effective information on diet, along with correction of nutrient deficiencies, then the "need" and apparent benefits of Lipitor largely dissolve. While there are occasional genetic anomalies that can improve with use of Lipitor and other statins, many, perhaps most, people taking these drugs really would not have to if they were just provided the right information.

Anyone following the discussions on these pages knows that wheat elimination is probably one of the most powerful overall health strategies available. Wheat elimination reduces real measured LDL quite dramatically. Provided you limit other carbohydrates, such as those from fruits, as well, LDL can drop like a stone. That's not what your doctor tells you. This approach works because elimination of wheat and limiting other carbohydrates reduces small LDL. Small LDL particles are triggered by carbohydrates, especially wheat; reducing carbohydrates reduces small LDL. Conventional LDL of the sort obtained in your doctor's office will not show this, since it is a calculated value that appears to increase with reduced carbohydrates, a misleading result.

Throw vitamin D normalization and iodine + thyroid normalization into the mix (both are exceptionally common), and you have two additional potent means to reduce (measured) LDL. Not restricting fat but increasing healthy fat intake, such as the fats in lots of raw nuts, olive oil, and flaxseed oil reduce LDL.

While I still prescribe statins now and then, a growing number of people are succeeding without them.

(Note that by "measured" LDL I am referring to the "gold standard," LDL particle number by NMR provided by Liposcience. A second best is measured Apoprotein B available through most conventional labs.)

In search of wheat: Emmer

23. June 2010 William Davis (13)
While einkorn is a 14-chromosome ancient wheat (containing the so-called "A" genome), emmer is a 28-chromosome wheat (containing the "A" and "B" genomes, the "B" likely contributed by goat grass 9000 years ago).

Both einkorn and emmer originally grew wild in the Fertile Crescent, allowing Neolithic Natufians to harvest the wild grasses with stone sickles and grind the seeds into porridge.

Having tested einkorn with only a modest rise in blood sugar but without the gastrointestinal or neurological effects I experienced with conventional whole wheat bread, I next tested bread made with emmer grain.

The emmer grain was ground just like the other two grains, cardiac dietitian Margaret Pfeiffer doing all the work of grinding and baking. Margaret added nothing but water, yeast, and a little salt. The emmer rose a little more than einkorn, but not to the degree of conventional whole wheat.

I tested my blood sugar beforehand: 89 mg/dl. I then ate 4 oz of the emmer bread. It tasted very similar to conventional whole wheat, but not as nutty as einkorn. Also not as heavy as einkorn, only slightly heavier than conventional whole wheat.

One hour later, blood sugar: 147 mg/dl. I felt slightly queasy for about 2-3 hours, but that was the end of it. No abdominal cramps, no sleep disturbance or crazy dreams, no nausea, no change in ability to concentrate.

I asked four other wheat-sensitive people to try the emmer bread. Likewise, nobody reacted negatively (though nobody tested blood sugar).

So it seems to me, based on this small, unscientific experience, that ancient einkorn (A) and emmer (AB) wheat seem to act like carbohydrates, similar to, say, rice or quinoa, but lack many of the other adverse effects induced by conventional wheat.

Modern wheat , Triticum aestivum, contains variations on the "A," "B," and "D" genomes, the "D" contributed by hybridization with Triticum tauschii at about the same time that emmer wheat hybridization occurred. It is likely that proteins coded by the "D" genome are the source of most of the problems with wheat products: immune, neurologic, gastrointestinal destruction, airway inflammation (asthma), increase in appetite, etc. This is consistent with observations made in studies that attempt to pinpoint the gliadin proteins that trigger celiac, the area in which much of this research originates.

If I ever would like an indulgence of cookies or cupcakes, I think that I will order some more einkorn grain from Eli Rogosa.

In search of wheat: Another einkorn experience

23. June 2010 William Davis (6)
Lisa is a trained dietitian. Unlike many of her colleagues, she has "seen the light" and realized that the conventional advice that most dietitians are forced to dispense through hospitals, clinics, and other facilities is just plain wrong. 

I know Lisa personally and we've had some great conversations on diet and nutritional supplements. I told Lisa about my einkorn experience and how I witnessed a dramatic difference between bread made from einkorn wheat and that made from conventional whole wheat. So she decided to give it a try herself. 

Here's Lisa's experience:


This past Friday, June 18th, I conducted my "Einkorn Wheat Experiment".

7 am 
FBG [fasting blood glucose] 97 mg/dl

8 am-9 am 
1 hour high-intensity aerobic workout

10:05 am 
BG 99

10:05 am 
I embarked upon the journey of choking down, I mean enjoying, the hefty piece of Einkorn bread. Wow, was that bread dense!  It was a lot of work chewing. 

10:50 am 
(45 minutes after consumption, wanted to see what BG did a bit before the 1 hr mark)  BG 153

11:05 am 
1hr PP 120

11:35 am 
90 mins PP [postprandial] 113

12:05 pm 
2 hours PP  114 ... at this time I ate an egg & veggie omelet for lunch.

12:50 pm 
BG 100

Before dinner 5:10 pm 
BG 88

I was surprised with the BG of 153. However, it was good to see my insulin response is reactive and decreased BG 33 points in 15 minutes to end up with a BG of 120 1 hr after the bread.  

So, it appears my response is similar. A slight elevation of BG at the 1 hour mark, but not to the degree of conventional whole grain wheat bread.  

Of note, also, was the fact that I cannot remember the last time I ate a piece of wheat bread of this magnitude that did not make me bloated... not at all: No cramps, no brain fog, no headache and, did I mention not bloated?  

I believe you are on to something with tolerance of Einkorn wheat for those of us with wheat sensitivities, in addition to its apparent lower glycemic response.

Along with Lisa, I asked four other people with various acute intolerances (all gastrointestinal) to conventional wheat, i.e., people who experience undesirable effects from wheat within minutes to several hours, to eat the einkorn bread. None experienced their usual reactions.

Obviously, this does not constitute a clinical trial. Nonetheless, I find this a compelling observation: People like myself who generally experience distinct undesirable reactions to wheat did not experience these reactions with einkorn.

Note, however, that einkorn behaves like a carbohydrate. No different, say, from brown rice or quinoa. However, unlike modern whole wheat flour from Triticum aestivum,  in this little experience there were no immune reactions, no neurologic phenomena, no gastrointestinal distress--just the blood sugar consequences.

While this may not be true for all people consuming einkorn, it suggests that primordial einkorn wheat is quite different from modern conventional wheat for most people.

Increased blood calcium and vitamin D

21. June 2010 William Davis (50)
Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

Heart health consultation with Dr. Joe D. Goldstrich

20. June 2010 William Davis (3)
Cardiologist, nutritionist, and lipidologist, Dr. Joe D. Goldstrich, is a frequent contributor to the Track Your Plaque Forum, where we discuss the full range of issues relevant to coronary health and coronary plaque reversal.

I have come to value Dr. Goldstrich's unique insights, especially in nutrition. Formerly National Director of Education and Community Programs for the American Heart Association and a physician at the Pritikin Center, his dietary philosophy has evolved away from low-fat and towards a low-carbohydrate focus, much as we use in Track Your Plaque. Like TYP, Dr. Goldstrich is always searching for better answers to gain control over coronary health. His unique blend of ideas and background has helped us craft new ideas and strategies. Dr. Goldstrich has proven especially adept at understanding how to incorporate new findings from clinical studies in our framework of coronary atherosclerotic plaque management strategies.

Dr. Goldstrich is offering to share his expertise with our online community. If you would like a one-on-one phone consultation with Dr. Goldstrich, you can arrange to speak with him at his HealthyHeartConsultant.com website.

Wheat aftermath

16. June 2010 William Davis (18)
Following my 4 oz whole wheat misadventure that yielded the sky-high blood sugar of 167 mg/dl, compared to einkorn wheat's 110 mg/dl, I suffered through a 36-hour period of misery.

After I obtained the blood sugar of 167 mg/dl, I biked hard for one hour. This yielded a blood sugar back down in the 80s. I felt spacey in the ensuing few hours, as well as a little queasy. However, about 12 hours later, I awoke with overwhelming nausea along with that hypersalivating thing that happens just prior to vomiting. It did not come to that, but persisted all through the following day.

The next morning, I could barely concentrate. Trying to read a study (admittedly on the complex topic of agricultural genetics), I had to read each paragraph 4 or 5 times. Abdominal cramps and a bloated feeling also developed, though I was able to eat.

The 2nd night was filled with incredibly vivid dreams and intermittent sleeplessless. I awoke about 5 times through the night, but periods of sleep were filled with detailed, colorful dreams. I dreamt that a large corporation was secretly trying to gain control over the world's water supply, and I snuck onto a complex underwater vessel that was exploring and mapping the coastline of the Great Lakes in preparation. Weird.

I recognized these odd feelings as various facets of wheat intolerance, since they were all reminiscent of feelings I used to experience before I removed wheat from my diet. They were amplified and compressed, likely because I had been wheat-free for so long.

The odd thing is that, despite the modest blood sugar effect of my einkorn experience, none of the gastrointestinal or neurologic effects of wheat developed. So far, two other people with acute gastrointestinal wheat sensitivities have consumed our einkorn bread, also without reproduction of their usual symptoms.

Einkorn contains gluten, though the structure of the many gluten proteins of einkorn differs from that of the wheat bread I consumed, an example of modern Triticum aestivum. 14-chromosome einkorn carries what biologists call the "A" genome, while Triticum aestivum has the combines genomes of 3 plants, the combination of the A, B, and D genomes. It is the D genome that contains the genes coding for the most obnoxious, immunogenic forms of gluten.

So einkorn may not be entirely benign, but it is a good deal less obnoxious than modern Triticum aestivum.

I am awaiting the reports from a few other people on their experiences.

In search of wheat: Einkorn and blood sugar

14. June 2010 William Davis (32)
There are three basic aspects of wheat's adverse health effects: immune activation (e.g., celiac disease), neurologic implications (e.g., schizophrenia and ADHD), and blood sugar effects.

Among the questions I'd like answered is whether ancient wheat, such as the einkorn grain I obtained from Eli Rogosa, triggers blood sugar like modern wheat.

So I conducted a simple experiment on myself. On an empty stomach, I ate 4 oz of einkorn bread. On another occasion I ate 4 oz of bread that dietitian, Margaret Pfeiffer, made with whole wheat flour bought at the grocery store. Both flours were finely ground and nothing was added beyond water, yeast, olive oil, and a touch of salt.

Here's what happened:

Einkorn wheat bread:

Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 110 mg/dl

Conventional wheat bread
Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 167 mg/dl

The difference shocked me. I expected a difference between the two, but not that much.

After the conventional wheat, I also felt weird: a little queasy, some acid in the back of my throat, a little spacey. I biked for an hour solid to reduce my blood sugar back to its starting level.

I'm awaiting the experiences of others, but I'm tantalized by the possibility that, while einkorn is still a source of carbohydrates, perhaps it is one of an entirely different variety than modern Triticum aestivum wheat. The striking difference in blood sugar effects make me wonder if einkorn eaten in small quantities can keep us below the Advanced Glycation End-Product threshold.

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.

Garland CF, Garland FC. Do sunlight and vitamin D reduce the likelihood of colon cancer? Int J Epidemiol. 2006 Apr;35(2):217-20.


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?

Fatal underdose

27. April 2008 William Davis (8)
Since vitamin D has been the topic of a fair amount of media coverage, I've received many questions about this fascinating "nutrient." A day doesn't go by without several nurses, friends, even fellow physicians stopping me to ask about vitamin D.

When I inform them that the average dose for females in this region (upper Midwest) is 4000-5000 units per day, 5000-6000 units per day for males, they are all surprised. "Then why did they say just take your multivitamin every day, or just drink your milk on the news?"

Many people are even more surprised, sometimes completely turned off, when they hear that, to be truly confident of adequate vitamin D dosing, a blood level of 25(OH) vitamin D3 needs to be checked. Now we're talking real hassle!

But there is no other way to do it. In order to obtain the full potential benefits of vitamin D, such as reduction in blood sugar and sensitization to insulin, reduction in cancer risk (especially prostate, colon, and breast), reductions in blood pressure, increased bone density, not to mention markedly increasing the likelihood of stopping or reducing your heart scan score, then achieving a desirable blood level of 25(OH) vitamin D is necessary.

Checking a blood level of vitamin D is no more difficult than having a cholesterol test, unless, of course, your doctor balks at the idea. (Time for a new doctor if that occurs.)

All too often, someone will be convinced they are taking a sufficient dose of vitamin D of, say 2000 units per day, only to discover that their blood level of 25(OH) vitamin D is something like 17 ng/ml--severe deficiency, sufficient to leave them exposed to all the undesirable consequences of vitamin D deficiency. Even though 2000 units per day represents 500% of the Institute of Medicine's recommended Adequate Intake for adults, to those familiar with the Track Your Plaque program it likely sounds like a child's dose.

Many variables enter into the equation in your body that determines your need for vitamin D: body size (heavier or larger people need more, with obese people often requiring enormous doses); sex (men need more than women); age (aging results in dramatic loss of ability to activate vitamin D in the skin); race; skin color (darker skinned people require more). Trying to guess your need is a fool's game. It's also a game that can seriously compromise your health and your hopes of ever stopping or reducing your heart scan score.



The message is clear: You cannot guess what your vitamin D need is. You cannot properly judge your vitamin D requirement by your age, body size, sex, or any other characteristic. Having a tan or a lack of a tan is a lousy indicator, as well. A simple blood level of 25(OH) vitamin D is an absolute necessity to gauge your vitamin D status, both before starting and while on your supplement.

Members of Track Your Plaque: Watch for the 30-some page booklet, The Track Your Plaque Complete Handbook on Vitamin D and Heart Health, which will be released in the next day or two.

Is direct-to-consumer drug marketing a failure?

23. April 2008 William Davis (4)
According to the poll just completed by 80 participants on The Heart Scan Blog, 50% of respondents said they were less likely to take a drug after viewing an advertisement for it. A whopping 3 (4%) said that they would be more likely to take the drug after viewing an advertisement.

I find that interesting. If half the people responding are less likely to become customers of a drug company, then how does the drug industry justify running around-the-clock, every-few-minute ads? Spending by the drug industry for direct-to-consumer (DTC) advertising has ballooned over the past few years, and is now well over $30 billion dollars per year.

Unfortunately, despite the views of the highly-educated, curious, think-for-yourself, health information-seeking sorts of people who read this blog, drug companies still come out on top by DTC advertising. Estimates vary, with a 2006 U.S. Government Accountability Office study reporting that, for every $1 DTC advertising, sales are increased by $2.20. A 2000 Harvard study showed a higher return of $4.40 for every advertising dollar spent.

I'm sure the drug companies themselves have a very tight accounting handle on their own set of figures. We may not be terribly fond of these people and their often suspect tactics, but they're not stupid. They are certainly not stupid when it comes to making money.

Interestingly, 80% of the funds spent on DTC advertising focus on the 20 or so most popular drugs, all of which are used for treatment of chronic conditions like high cholesterol and high blood pressure, markets that are large and long-term. It pays very little to advertise drugs that may serve small markets for a short period. The implicit message is that this is not at all about informing the public. It is about advertising to grow revenues and profits--pure and simple.

It makes me wonder what the results of our poll would have been had we conducted it in 2000 before many people hadn't yet been brought to the brink of vomiting from the endless onslaught of commercial after commercial, complete with smarmy spokespeople (a la Lipitor's Dr. Robert Jarvik). What will it show in two years? Will the broader public join the more informed people who read this blog and become increasingly inured to the hard sell tactics?

For further discussion of this topic, click here for a reprint of an August, 2007 New England Journal of Medicine study, A Decade of Direct-to-Consumer Advertising of Prescription Drugs provides background, along with commentary on the impact of DTC drug marketing since the FDA allowed it 10 years ago. (Because it is a study and not an editorial, the editors fall short of making any recommendations for improvement or calling for a moratorium.)

Cheerios and heart health

22. April 2008 William Davis (11)


Anna responded to the Heart Scan Blog post, Can you say "sugar"? with the following wonderfully telling comment:

A measured bowl of Cheerios and a bit of milk (whole, because it's what I had), equal to 75 grams of carbohydrate, gave me the highest ever blood glucose reading from a food (not counting glucose solution from a Glucose Tolerance Test). I was attempting a "homemade" version of a 3 hr GTT before going to my doctor with my concerns about my BG.

My BG started to rise very fast within 15 minutes after eating the cereal, peaked at about 250 mg/dL at 45 minutes, then slowly dropped. By about 60-75 minutes, I experienced strong hunger and carb cravings as the BG began to slowly drop, and by about 2.5 hours after eating, my BG had suddenly dropped quite low (in the low 70s) and I had developed a nasty hypoglycemic feeling (shaky, irritable, craving sugary foods, headache, etc.).

It's hard for me to see "heart healthy" Cheerios (or any other highly processed breakfast cereal) as anything other than a bowl of pre-digested sugar that contributes to roller coaster blood glucose and insulin levels, which a great way to start anyone's day. Certainly, I don't do well with Cheerios because I clearly have a damaged glucose regulatory system (probably a diminished or absent first phase insulin response, but I can't imagine that it is doing any good for people with healthy glucose regulation, either.

I banned prepared cold cereals from our house. If my 9 yr old son gets cereal at all at home, it's whole groats (not even rolled or steel cut because those aren't truly "whole grain" anymore), soaked overnight in some water and a tsp of plain yogurt (soaking neutralizes phytates and reduces cooking time), then cooked about 8-10 minutes (water added as necessary). Sometimes I add a bit of quinoa or almond meal prior to soaking to boost the protein content a bit. I garnish with a pat of butter, some heavy cream, and a dusting of cinnamon. If I'm feeling *really* indulgent, I drizzle about 1 tsp of Grade B maple syrup on top (Grade B is stronger in flavor and so less can be used). I don't eat this cereal myself, and truthfully, I'd rather my son not, either, but he sometimes wants cereal. It's the least damaging compromise I can come up with that we can both live with.


I have also seen diabetic effects from Cheerios: rises in blood sugar, exagerration of small LDL, drops in HDL, rises in triglycerides. Yes, it may reduce LDL a small quantity, but so what?

The Cheerios "heart healthy" claim is based on a piece of research apparently performed by Dr. Donald Hunninghake at the University of Minnesota and reported in 1998:

A study conducted at the University of Minnesota Heart Disease Prevention Clinic and published as "Cholesterol-Lowering Benefits of a Whole Grain Oat Ready-to-Eat Cereal" in the May issue of the Nutrition in Clinical Care journal in 1998, showed that people can lower their blood cholesterol by an average of 3.8% over six weeks by enjoying 3 cups of cold cereal made with 100% whole grain oats everyday as part of the meals and snacks in a healthy lower-fat diet.

(Unfortunately, I could not locate the actual publication. It doesn't mean it doesn't exist; I just couldn't locate it. Perhaps it's in a small journal not entered into the online publication database.)

The purported effects of Cheerios should not be confused with that of actual, intact oat bran, as suggested by studies such as those of Brenda Davy et al, High-fiber oat cereal compared with wheat cereal consumption favorably alters LDL-cholesterol subclass and particle numbers in middle-aged and older men, in which significant reductions in LDL particle number and small LDL (NMR) were obtained. (This study was also supported by Quaker Oats.) Several studies have shown that oat bran does indeed reduce LDL cholesterol, sometimes as much as 30-50 mg/dl. Cheerios can not even come close to this.

If Cheerios were nothing more than finely pulverized oats, then perhaps it wouldn't be so bad. But add corn starch and sugar, and you have ingredients that have potential to distort LDL particle size and yield blood sugar-escalating effects like those described by Anna.

The gravity of perpetuating these myths is brought home by a testimonial posted on the website for Cheerios:

“I had unexpected open heart surgery a year ago. As I adopted heart health habits during my recovery, I realized that I should have been eating the Cheerios cereal I carried around in a plastic baggie so many years for my kids!”

The IF Life: Intermittent fasting

21. April 2008 William Davis (4)
There's a wonderful blog called The IF Life: Intermittent Fasting and Instant Freedom. It is written by personal trainer (and apparently former corporate bigshot), Mike O'Donnell.

Mike has a great take on brief, intermittent fasting that I found helpful and I believe you will also.






Intermitent Fasting 101: How to Start, Part I

The biggest question people have is how to effectively use IF (intermittent fasting) to achieve their goals and maximum results. These results and goals can vary by each person with fat loss, muscle gain, better health, improved performance in your sport of choice and more. With that comes the individuality of what is a person’s insulin resistance, current body composition (bodyfat%), daily lifestyle, eating habits, macronutrient ratios (carbs/protein/fat), type of exercise program, frequency and volume of training, recovery demands, and so forth. You are unlikely to find 2 people with the same set of parameters and same exact responses to an IF protocol. What does this mean? Well just that we need to start with a basic IF program, and then learn how to monitor results and adjust as we go. Even down the road things will change as you will improve health, lower insulin resistance and maybe change performance and recovery needs. So nothing is ever just one set way. Life is dynamic (always changing and evolving) and so should be the way we see our own journey for health and fitness.

What is IF?

For those that may not be familiar to the term, intermittent fasting is just taking times of fast (no food) and working them into your lifestyle. This can be either daily or a couple times a week (will get into that more below). Benefits include improving insulin resistance (which you will hear alot about as being the #1 key marker in so many health factors including weight loss, muscle gain, performance, recovery, anti-ageing and disease prevention) and giving the body a chance to do some internal cleaning (or housework), which can lead to improved immune function and overall health. If you want to see studies of all the benefits of IF/CR, please the resources page.


How do I begin to IF?

Is there only one set way in which to do IF? No. I could easily come up with 10 different IF protocols based on 10 people’s individual’s needs, lifestyle, exercise, goal, macronutrient ratios, and so forth. We will keep it simple and give the 2 most frequent and basic options.

Daily Fasting: Typically done every day and only giving the person a smaller eating window in which to get their calories. (for example, a 18hr daily fast would mean someone would only eat every day between the hours of Noon and 6pm). You will see varying times from 15-19 hours for daily fasting.
Fasting 1-3x a week: This could also be called alternate day fasting/calorie restriction (for those doing it every other day). This is just fasting of usually longer periods 18-24 hours but only 1-3x a week. Many variations to play with here.
“But which one is better and how to I do it now if I want…….”. Whoa, slow down. I know many have questions but let’s still try to keep this simple for now and expand into more specifics later. So far many people have experimented with both types of IF and have seen great results. But you also have to take into account all the other variables such as what is the person eating in that window? Is is junk food? Is it low carb? How many times a week are they doing it? Are they overweight and wanting just fat loss? Are they lower bodyfat but looking for improved performance and health? How many times a week are they exercising? What kind are they doing and what intensity? The list can go on and on, but let’s start to analyze the 2 types of IF and let you decide which one best suits your lifestyle.

Daily Fasting (15-19 hours):

The Advantages are:

--simple eating strategies for every day
--even people that may not eat 100% clean foods can see weight loss due to the smaller window and lower calorie total per day


The Disadvantages are:

--Can possibly lower metabolism if calories are too low for too long (not what you want if your #1 goal is weight loss)
--Not getting enough food in the smaller window may also lead to muscle loss for more active people (not good)
Fasting 1-3x a week:


The advantages are:

--Allows a person to make sure they are getting enough calories on the non-fasting days, and then just keeps to a simple small feed window (if any) on the IF days.
--Simple thinking for people who do not have experience in how to eat clean to eat one day, and then eat in a smaller window the following day (alternate day fasting/CR). This can achieve fat loss for people who are mostly overweight and may not be too active. (of course don’t get me wrong, that eating healthy is our main goal but this can be a good step for some people to start their weight loss jounrey and learn how to make better choices as they go)


Disadvantages:

--Doesn’t force a person to make better choices with their food (as one could probably eat junk one day, and then fast the next and still lose weight). Not something we want long term because this is not going to improve your other health markers (diseases prevention, insulin resistance) like a good IF program on healthy foods.


Again I can’t say it enough, as there are so many variables to play with in an IF program. Some people may say “well it didn’t work for me” or “I didn’t gain any muscle”. Well unless I know everything about what you do for exercise daily, your total calories, when you eat and your macronutrient ratios (protein/carbs/fats), I can’t even begin to help. IF is a simple tool to start with, but you have to take full responsibility for your own health and progress and learn when it is not working and when to change things up! Like I said, if it is NOT working then stop IF and rethink your attack plan (or get a professional to coach you on it).

So to sum up, here are some examples of what you can play with:

Daily Fasting of 15-19 hours. I would highly suggest that if you do this make sure you are recovering from your exercise and start only Mon-Fri and give yourself the weekends to eat all day (hopefully with healthy choices of course)


Fast 1-2x a week to start if you have never done any fasting or do not know how to eat healthy and control your macronutrients. Start with 1-2 days a week with fasts of 18-20 hours (I wouldn’t start with 24 hr fasts to begin as most people can not handle the hunger cravings and in turn will just end up eating all the wrong foods when they do eat) and say eat only from say 1pm-6pm for example. Drink lots of water (add lemon, your liver will appreciate it! and it will help with the hunger). For example, fast Wed and Sun (or whatever days fit into your schedule)

Or you can do a mixed approach and fast every other day for a small eating window. For example eat all day Mon, only 12-6pm on Tues, all day Wed, 12-6pm on Thurs, etc. Start with bigger eating windows and make them smaller as you get used to fasting. This approach may work for people who have alot of weight to lose and can not (I should really say “will not” as everything is a choice!) eat 100% healthy for the moment. This approach may not work for more advanced people who have a high activity level unless you are getting a ton of health calories in that fasting window.
“So What Do I Eat on the Fasting Days?”

That’s the best part, you should be able to eat unlimited healthy foods (healthy proteins, fats, veggies, fruit, nuts…see Paleo Diet in the resources page). If you are eating more processed foods, breads and other high calorie intakes then you may have to monitor and control portions. Please know this is NOT about chronic calorie restriction or starving yourself. When I do weeks of eating 1-7pm, I am eating a ton of protein and veggies (complex carbs pwo also). I am hardly starving myself. I am not taking in 4000 cal a day however, so my daily average of say 2200-2500 cal is still low compared to the alternative. If you want to lose weight of course you will need a calorie deficit to pull the “stored energy” out of fat cells. That is the advantage to eating “Paleo”, you can’t over eat on protein, healthy fats, fruits (in moderation) and veggies. If you are making bad choices or starving yourself on IF, you may lose the effectiveness or slow progress. All goes back to the fact that if it is not working, then change something up! (there is always something that can be changed…and food choices is the #1 place to start!) I don’t count calories, and by eating natural foods that have been around for 100s of years….I don’t need to! (eating healthy natural foods will not only help you lose weight but also improve your health and lower your risks of diseases….so eating for health should always be the #1 goal in any program)

Hopefully this will give a good overview while trying to keep it simple. Remember it’s your journey to take, measure progress and adjust things that are not working. Start with one approach, and modify it. Who knows, your approach may change every couple months and that is ok. Life is always changing and so should your approach to health and fitness (as the body always responds better to change than sticking with the same eating/exercise approach for a long period of time).

Warfarin is scary stuff

19. April 2008 William Davis (16)
Gilbert is a 58-year old high school science teacher.

When I first met Gil, he'd been having bouts of atrial fibrillation and had required various medications to suppress recurrences of the rhythm. However, because his rhythm proved somewhat difficult to control, his electrophysiologist (heart rhythm specialist) prescribed warfarin to reduce the risk of stroke. With atrial fibrillation, because of blood stagnation (in the left atrial appendage) in the heart, there is a stroke risk of approximately 8% per year. Warfarin reduces this risk substantially, to about 2%.

I met Gil because he had a cholesterol disorder. In my practice, the first step in gauging the implications of a lipid or lipoprotein disorder is to obtain a heart scan. If the heart scan score is zero, great. It means that we have plenty of time to treat the disorder since risk for cardiovascular events is near zero also; it means less intensive efforts less intensive efforts are necessary. But if the heart scan score is, say, 1200, then an aggressive approach in short order is required, since the risk for heart attack may as high as 20-25% per year, even in the absence of symptoms.

Gil's heart scan score: 787--high and posing a risk for heart attack of about 5-10% per year without preventive efforts. Gil did indeed prove to have a complex lipoprotein disorder, as well as high blood pressure, vitamin D deficiency, and several other potential contributors to coronary plaque.

Gil did just about everything right: He exercised, followed the recommended diet, achieved better than the Track Your Plaque 60-60-60, lost 18 lbs of abdominal fat.

Gil's rhythm stabilized for several months, only to have atrial fibrillation break through again. So Gil's electrophysiologist re-prescribed warfarin.

18 months later, Gil's 2nd heart scan score: 1410--a near doubling. Unsettling to Gil and to us, to say the least.

How can this happen in the face of perfect lipids/lipoproteins, correction of hidden causes like lipoprotein(a) and inflammation, along with a vigorous lifestyle effort?

I fear that the culprit might be warfarin.

Warfarin, better known by its brand name, Coumadin, may have some effects that intersect with the Track Your Plaque mission of reducing coronary plaque.

It is no secret that, beyond the obvious risk of bleeding from blood thinning, warfarin also may:

--Accelerate aortic valve calcification
--Accelerate calcification of the framework of the mitral valve (the mitral "anulus")
--Accelerate osteoporosis
--Induce an artificial situation of vitamins K1 and K2 deficiency.

The vitamin K1 deficiency is the route by which blood thinning is achieved. However, the K2 deficiency may have undesirable consequences, among which are the above list of various pathologic calcifications.

I therefore wonder if warfarin dramatically accelerated the coronary calcium that we track to gauge the progression of coronary atherosclerosis. One experience is hardly sufficient reason to sound the alarm. It is also difficult to pinpoint the cause of the explosive growth in Gil's coronary calcium specifically on warfarin.

That all said, I am quite certain it was the warfarin.

Unfortunately, some people are unavoidably committed to warfarin, such as those with specific genetic blood clotting disorders, prosthetic valves, prior deep vein thromboses and pulmonary emboli, etc.--serious reasons. Until an alternative emerges, warfarin remains a necessity for some people. (No, nattokinase is NOT an alternative, at least not one that would permit survival.)

My personal policy is that warfarin be used only when absolutely necessary and the gains markedly outweight the risks--including that of possible accelerated calcification of multiple sites.

Whether we will be able to get Gil off warfarin and potentially gain control over his coronary disease/plaque/calcium remains to be seen. I sure hope so.

Wheat-free 2007

1. January 2007 William Davis (4)

Long ago, most of us made the change of reducing saturated fat in our diet. Few people now rely on butter (despite the idiotic butter vs. margarine controversy), full-fat dairy products, fried foods, and greasy meats. That's a healthy change, since saturated fat has conclusively been tied to various cancers, high blood pressure, rise in LDL, and is calorie-dense.

But if there were just one change you were to make beyond a reduction in saturated fat, a change that would translate into dramatic health benefits, it would be a drastic reduction, even elimination, of wheat products.

People do indeed eat enormous quantities of wheat flour-containing products. U.S. per capita consumption of wheat flour was 110 pounds in the early 1970s, and rose to 141 pounds in 1991. It's even higher now. 20% or more of most people's caloric intake every day is provided by wheat flour products.

Wheat containing foods are tasty and convenient. Witness the popularity of bagel shops, the goodie counter at Starbuck's, the proliferation of crackers, breads, and breakfast cereals at the grocery store. Patients are horrified when I suggest that they find a substitute for the sandwiches they eat every day. Even Mom said they were okay!

You're unlikely to hear much about this from the popular press. The wheat industry is enormous and exerts extraordinary clout, just like the drug industry. Texas alone farms 6 million acres of wheat, yielding over $2 billion for the state's economy. The "wheat chain" is complex and far-reaching: growers, processors, food manufacturers, the transportation industry, retailers, chemical producers, and on and on. Wheat futures are traded on the Chicago Board of Trade. Wheat is a major export industry for the U.S.

Of course, these are not evil people, intent on corrupting your health. In fact, most of them are probably working under the perception that they are raising a healthy product. The point is that the notion that wheat is healthy is deeply entrenched in the minds and economy of the U.S. Don't expect to hear unbiased commentary on the health effects of wheat products from most media sources.

What can you expect if you sharply reduce or eliminate wheat? The majority of people:

--Feel like a cloud has been lifted from their thinking.
--Don't experience the afternoon blah or tired feeling after lunch.
--Lose weight, sometimes substantial quantities.
--Raise HDL.
--Reduce small LDL.
--Reduce triglycerides, particularly if they start >100 mg/dl.
--Reduce blood sugar.

The reduction in small LDL can be especially impressive.

For most people, reducing or eliminating wheat is a sacrifice, a major change in food choices and even a loss of convenience. But the health benefits for most people can be dramatic.

Is vitamin D a "vitamin"?

29. December 2006 William Davis (5)
Vitamins are crucial participants in the body's reactions and are obtainable from food. Vitamin C, for example, comes from citrus fruits and vegetables. Vitamin K comes from green vegetables. The B vitamins are found in meats, soy, dairy products, and grains. Vitamin A comes from carrots, squash, and other orange and green colored vegetables.

How about vitamin D? What foods contain vitamin D? The list includes:


Food International Units(IU) vitamin D per serving

Cod liver oil, 1 Tablespoon 1,360
Salmon, cooked, 3½ ounces 360
Mackerel, cooked, 3½ ounces 345
Tuna fish, canned in oil, 3 ounces 200
Sardines, canned in oil, drained, 1¾ ounces 250

Milk, nonfat, reduced fat, and whole, vitamin D fortified, 1 cup 98
Margarine, fortified, 1 Tablespoon 60
Pudding, prepared from mix and made with vitamin D fortified milk, ½ cup 50
Cheese, Swiss, 1 ounce 12

Ready-to-eat cereals fortified with 10% of the DV for vitamin D, ¾ cup to 1 cup servings (servings vary according to the brand) 40

Egg, 1 whole (vitamin D is found in egg yolk) 20
Liver, beef, cooked, 3½ ounces 15

(Modified from the Office of Dietary Supplements, National Institutes of Health)


You'll note that the only naturally-occurring food sources of vitamin D are the modest quantities in fish, egg yolks, and liver. All the other vitamin D-containing foods like cereal, milk, and other dairy products have vitamin D only because humans add it.

It takes me (personally) 6000 units of vitamin D per day to bring my blood level to an acceptable 50 ng/ml. To obtain this from eating salmon, I would have to eat 58 ounces, or 3 1/2 pounds of salmon--every day. Or, I could eat 30 cans of tuna fish.

If I didn't want to eat loads of fish every day, I could drink 60 glasses of milk every day. After I recovered from the diarrhea, my vitamin D might be adequate, provided the milk indeed contained the amount stated on the label (which it often does not when scrutinized by the USDA).

If vitamin D is a vitamin, how are humans supposed to get sufficient quantities? I don't know anybody who can eat 3 1/2 lbs of salmon per day, nor drink 60 glasses of milk per day. But aren't vitamins supposed to come from food?




The problem is that vitamin D is not really a vitamin, it's a hormone. If your thyroid hormone level was low, you'd gain 20, 30, or more pounds in weight, your blood pressure would skyrocket, you'd lose your hair, become constipated, develop blood clots, be terribly fatigued. In other words, you'd suffer profound changes. Likewise, if thyroid hormone levels are corrected by giving you thyroid hormone, you'd experience profound correction of these phenomena.

That's what I'm seeing with vitamin D: restoration of this hormone to normal blood levels (25-OH-vitamin D3 50 ng/ml) yields profound changes in the body.

If there's one thing that I've come across lately that packs extraordinary potential to help us in reducing heart scan scores, it's the vitamin--sorry, the hormone--cholecalciferol, or D3.

Heart scan curiosities 3

28. December 2006 William Davis (0)

Note the shape of the chest in this 64-year old man. The front of his chest (upper portion of scan) is concave. In other words, if you were looking at this man (shirtless, of course) face to face, his chest would bow inward, rather than the usual outward configuration. The official name for this is "pectus excavatum".





Compare this to the normal chest in the second image, in which the chest is convex. Face to face, the chest would bow slightly outward.















What does it matter? The pectus excavatum in and of itself has no importance, just a curiousity. (I personally find this surprising, given the fact that the heart actually appears squashed by the sternum, or chest wall.) However, it is commonly associated with a "floppy" mitral valve (also called mitral valve prolapse), a common congenital disorder of the mitral valve often accompanied by a slender build, loose joints, and even a nervous disposition. Occasionally, in its more severe forms, the aorta is also enlarged. (This man's aorta is not enlarged.)

So, while we can't actually visualize the mitral valve by a CT heart scan, we can surmise that he likely has a floppy mitral valve, is slender, is probably a nervous sort, and has long limbs with loose joints. He probably required braces as a child, since many people have a phenemenon of "crowded teeth". The roof of his mouth, or hard palate, probably unusually high up in the mouth. He probably has a "weak chin", meaning a less prominent protuberance of his chin. His fingers and toes are likely unusually long and slender.

It could mean that some attention and exploration of how floppy his mitral valve might be could be useful, e.g., an ultrasound or echocardiogram. He might even require oral antibiotics at the time of any oral or some gastrointestinal procedures, since floppy valve are more susceptible to blood infections when potentially "dirty" orifices are instrumented.

All that from a heart scan!

Gratitude

24. December 2006 William Davis (2)
The holidays and the end of the year may be a good time to reflect on how grateful we should be for having the freedom to discuss the ideas we share on this Blog, the Track Your Plaque website, online and offline.

Although I rant and rave against the status quo in heart disease, the shameful profiteering of my colleagues and hospitals, the cut-throat marketing practices of drug and device manufacturers, I am truly grateful that, in the U.S., I have the extraordinary freedom to say these things. You have the freedom to agree or disagree and none of us pays a price for truth.

I've been reflecting myself a great deal on this idea of happiness and gratitude being a critical component of coronary plaque regression and dropping your heart scan score. (See The Heart Scan Blog from earlier this week.) The more I think about this, the more I think that it is indeed true: Harboring anger and resentment, regrets, irritability, all those petty emotions that most of us know are not good for us, erode our chances for success in dropping your heart scan score.

We could rationalize it this way: Anger and other negative emotions are adrenaline-driven states, also characterized by activation of the "sympathetic" nervous system. (Despite its name, the sympathetic system is not sympathetic, as in compassionate; its the "fight-or-flight" activator that accelerates heart rate and blood pressure.)

Happiness, contentment, and gratitude are "parasympathetic" states characterized by slower heart rates, deeper respiration, greater variation in beat-to-beat heart rates (a powerful predictor for health and the basis for the HeartMath program of Lew Childre), lower blood pressure, and even a subtle change in brain waves. In other words, happiness is not just a mental and emotional state, it is a constellation of physical phenomena.

Even though I pick on Dr. Dean Ornish for his stubborn adherence to the outdated low-fat mantra, I do agree with him on the value of happiness. His book, Love and Survival, articulates this concept. Ornish has even said on several occasions that it wasn't the diet that was most important but the connection and warmth that was created by the comraderie created by participation in the Ornish Program group sessions.

I am personally grateful that the concepts I promote are gaining a following and that I can say so without fear of prosecution. I am grateful that Track Your Plaque followers are not just sharing our concepts, but obtaining genuine and powerful health advice that will help keep them home and healthy, away from hospitals, procedures, and the dangers of heart disease.

I hope you share in my gratitude and are thankful for all the truly wonderful things that surround us. I wish you all a wonderful holiday and long, healthy life filled with gratitude.

A Track Your Plaque failure

23. December 2006 William Davis (0)
We recently had a man suffer a heart attack after beginning the program. Let me tell you the details.

Jerry's heart scan score 781, age 53. Multiple lipoprotein abnormalities: HDL 32 mg/dl, triglycerides 279 mg/dl, nearly all of his LDL was in small particles with an "effective" LDL (LDL particle number), and very high IDL. So Jerry added fish oil 6000 mg per day, niacin, and vitamin D to the statin drug prescribed by his primary physician. Jerry added oat bran, ground flaxseed, and tried to eat fish at least once per week.

However, Jerry continued to smoke. He'd smoked for 40 years (!), up to 2 packs per day, and just reasoned that it was too late to quit. He also continued to indulge in the packaged, processed foods that were part of his convenience story business.

Jerry's stress test was normal--no chest pain, normal EKG, normal images of blood flow, though he was somewhat breathless, likely from his lung disease from smoking.

Two months into his program, he abruptly experienced severe crushing pain in his chest. Because he was traveling, he ended up in a small local hospital. A failed angioplasty led to urgent coronary bypass surgery.

Jerry's alive. Now he's a non-smoker. He's got the pursed lips and peculiar breathing pattern that smokers get, but he's breathing.

Lesson: In the face of the most powerful program for heart disease known, it can still be overpowered by Twinkies, Hoho's, pretzels, chips--and cigarettes.

The new year is approaching. Be grateful for another year of healthy life and commit to a new year of even greater health. If you're a smoker, there's no choice: you've got to quit.

Are you more like a dog or a rabbit?

Dr. William Roberts, editor of the American Journal of Cardiology and cardiovascular pathologist, is a perennial source of clever ideas on heart disease.
In a recent editorial, Dr. Roberts comments:








"Because humans get atherosclerosis, and atherosclerosis is a disease only of herbivorers, humans also must be herbivores. Most humans, of course, eat flesh, but that act does not make us carnivores. Carnivores and herbivores have different characteristics. (1) The teeth of carnivores are sharp; those of herbivores, flat (humans have some sharp teeth but most are flat for grinding the fruits, vegetables, and grains we are built to eat). (2) The intestinal tract of carnivores is short (about 3 times body length); that of herbivores, long (about 12 times body length). (Since I am 6 feet tall my intestinal tract should be about 60 feet long. As a consequence, if I eat bovine muscle [steak], it could take 5 days to course through those 20 yards.) (3) Body cooling for carnivores is done by panting because they have no ability to seat; although herbivores also can pant, they cool their bodies mainly by sweating. (4) Drinking fluids is by lapping them for the carnivore; it is by sipping them for the herbivore. (5) Vitamin C is made by the carnivore's own body; herbivores obtain their ascorbic acid only from their diet. Thus, although most human beings think we are carnivores or at least conduct their lives as if we were, basically humans are herbivores. If we could decrease our flesh intake to as few as 5 to 7 meals a week our health would improve substantially."



You can always count on Dr. Bill Roberts to come up with some clever observations.

I think he's right. Some of the most unhealthy people I've known have been serious meat eaters. Most of the vegetarians have been among the healthiest. (I say most because if a vegetarian still indulges in plenty of junk foods like chips, crackers, breakfast cereals, breads, etc., then they can be every bit as unhealthy as a meat eater.)

Should you become a vegetarian to gain control over coronary plaque and other aspects of health? I don't believe you have to. However, modern livestock raising practices have substantially modified the composition of meats. A steak in 2006, for instance, is not the same thing as a steak in 1896. The saturated and monounsaturated fat content are different, the pattern of fat "marbling" is different, the lean protein content is different. Meat is less healthy today than 100 years ago.

Take a lesson from Dr. Roberts' tongue-in-cheek but nonetheless provocative thoughts. Pardon me while I chew on some carrots.

Are happy people more likely to reduce heart scan scores?

18. December 2006 William Davis (0)
I was talking to Darryl, a patient today: 71 years old with a heart scan score of 378, as well as an enlarged aorta (4.5 cm).

We had identified numerous lipoprotein abnormalities 12 months ago and advised him on a program for correction. His patterns included small LDL, high triglycerides, sky-high IDL (VERY important when you have an enlarged aorta), and lipoprotein(a). Blood pressure was also high, another crucial fact to correct when the aorta is enlarged.

Anyway, Darryl corrected lipoproteins to perfection: basic lipids were substantially better than 60-60-60; lipoprotein(a) was reduced well into the desirable range; IDL was eliminated; blood pressure was 108/64. Repeat heart scan score: 354.

There's nothing spectacular about Darryl's story, except that, despite these issues, Darryl was a happy man. He smiled throughout our conversation. He has told me on several occasions how grateful he is for the life he has.

Darryl is not wealthy. He retired around 4 years ago and fills his day with helping his wife, walking outdoors, helping out at his church, and contributing to the care of his grandchildren. Through all this Darryl is incurably, unfailingly, and irrepressibly happy.

It made me think back through all the other people who've also had great succes in their Track Your Plaque program. It struck me that, for the most part, they too were a happy bunch: generally optimistic, happy, not overly stressed nor prone to extremely stressful responses to stressful situations. All seem to also be grateful for the good in their lives, though most had no more money than the average person and had their share of difficulties in life. In fact, I can only recall one person who reversed coronary plaque who was an angry, pessimistic personality. Just one.

Could it be that happy, optimistic people are more likely to reverse coronary plaque? It would, after all, be consistent with all the other observations that type A personalities have more heart attack, etc.

Anyway, this is just an informal observation but one that seems very consistent. Track your plaque--and be happy!

Don't overdo the vitamin D

17. December 2006 William Davis (1)
As time passes and I advise more and more people to supplement vitamin D, I gain increasing respect for this powerful "vitamin". I am convinced that vitamin D replacement is the reason for a recent surge in our success rates in dropping CT heart scan scores. I believe it is also explains the larger drops we've been witnessing lately--20-30%.

But vitamin D can be overdone, too. Too much of a good thing . . .

Despite being labeled a "vitamin", cholecalciferol is actually a hormone. Vitamins are obtained from food and you can thereby develop deficiencies because of poor intake. Deficiency of vitamin C, for instance, arises from a lack of vegetables and fruits.

Vitamin D, on the other hand, is nearly absent from food. The only naturally-occuring source is oily fish like salmon and sardines. Milk usually has a little (100 units per 8 oz) because milk producers have been required by law to put it there to reduce the incidence of childhood rickets.

A woman came to me with a heart scan score of nearly 3800, the highest score I've every seen in a woman. (Record for a male >8,000!) She was taking vitamin D by prescription from her family doctor but at a dose of 150,000 units per week, or approximately 21,000 units per day. This had gone on for about 3-4 years. This may explain her excessive coronary calcium score. Interestingly, she had virtually no lipoprotein abnormalities identified, which by itself is curious, since most people have some degree of abnormality like small LDL. Obviously, I asked her to stop the vitamin D.

Should you be afraid of vitamin D? Of course not. If your neighbor is an alcoholic and has advanced cirrhosis, does that mean you shouldn't have a glass or two of Merlot for health and enjoyment? It's a matter of quantity. Too little vitamin D and you encourage coronary plaque growth. Too much vitamin D and you trigger "pathologic calcification", or the deposition of calcium in inappropriate places and sometimes to extreme degrees, as in this unfortunate woman.

Ideally, you should have your doctor check your 25-OH-vitamin D3 blood levels twice a year in summar and in winter. We aim for a level of 50 ng/ml, the level at which the phenemena of deficiency dissipate.

"It must have been the statin"

13. December 2006 William Davis (0)
After four years of trying, Randy finally reduced her heart scan score. It not only dropped, it plummeted. After four previous scans that showed 25% or more increases, she'd finally dropped her score 23%. (I Blogged about Randy's case a few weeks ago.)

Randy also works for a cardiologist. When she told him that she had reversed her coronary plaque and reduced her heart scan score by 23%, he said, "It must have been the statin agent."

Randy was indeed on a statin drug at a low dose. But she also had taken great efforts in exercise, food choices, fish oil, and vitamin D. In fact, her score had progressed dramatically while she was taking the drug. Put simply, it was not the statin.

But that is the mindset of the conventionally thinking cardiologist. Stent, bypass, or statin drug--what else is there? Even with crystal clear evidence for coronary plaque regression, they refuse to acknowledge that tools that are not in their everyday consciousness could have achieved so spectacular a result.

Given a choice, 9 out of 10 cardiologists would rather put a stent in and walk away $2000 richer for an hour of work. Don't allow them to have this choice. Take control now.

Statin Drugs May Help the Healthy:
Cholesterol-Lowering Statin Drugs May Benefit People Without Heart Disease

That's the headline on WebMD, reporting the findings of a recent study published in the Archives of Internal Medicine. In reality, it wasn't really a study at all, but a re-analysis of previously published data, a so-called meta-analysis.

Nonetheless, the University of Toronto group re-analyzed the results of several studies, pooling data on 28,000 people, none of whom had known coronary disease. The results were similar to the results of the studies that were reported individually: a 29% reduction in heart attack and other "events" in people taking statin drugs.

What's surprising to me is this notion that statins, or any other treatment for that matter, prevent heart attack in people without heart disease. This is idiotic. Of course they had coronary heart disease. You can't have a heart attack in the absence of coronary disease. (There are very rare exceptions, like cocaine users, who experience coronary spasm from the drug).

What the study shows is that people with unrecognized heart disease experienced a reduction in heart attack. What it also means is that many, many people truly without heart disease were unnecessarily treated. As you'd predict, the drug manufacturers love this sort of broad, untargeted use of their drugs. It's an approach that brings in billions of dollars of revenues. The article on WebMD, in fact, was accompanied by three ads for various cholesterol drugs on this single page story.

What if only people with heart disease, as identified by CT heart scan scores, were treated? You would indeed witness an even larger reduction in heart attack risk, because the group receiving treatment both has the disease and is thereby at greater risk. Treatment should yield even greater risk reduction than treating broad groups who superficially appear to not have heart disease.

Ignore this nonsense about statin drugs reducing heart attack risk in people without heart disease. If you don't look for it, you won't know you have it. Once again, you can be lots smarter than the media. Get a heart scan and find out if your risk is worth reducing.
