Excessive Heart Procedures Makes New York Times Headline

18. August 2006 William Davis (0)

One example of flagrant cardiac procedure excess has made New York Times headlines:


Heart Procedure Is Off the Charts in an Ohio City
The number of angioplasties performed in Elyria is so high that Medicare is starting to ask questions.

(The full article can be accessed through the New York Times website at http://www.nytimes.com/2006/08/18/business/18stent.html?pagewanted=2&ei=5094&en=b81be5f43f98a99b&hp&ex=1155960000&partner=homepage)



Cardiologists in little Elyria, Ohio, about a 30-minute drive west of Cleveland, do more coronary angioplasties and insert more stents than any other location in the U.S.--four times more than the national average, three times more than the Cleveland average. They perform even more than the recently-indicted cardiologist in Louisiana, who performed twice the national average of procedures.


The Times article, part of a series about financial incentives in medical care, provides a responsible and incredibly balanced report on the situation in Elyria. I have to give them credit, because from the eyes of a colleague (myself), this looks like blatant and extreme profiteering: "cathing for dollars".

I find it outrageous that this group of cardiologists claims that they have some special insight into heart care that justifies this extraordinary reliance on heart procedures. There's bound to be variation in practice patterns, but this is so outside the norm that I believe criminal behavior will be exposed. In fact, I believe that even the "norm", or average, rate of procedures is also excessive.

This is symptomatic of the perverse equation in heart disease care. If there's money to be made in major heart procedures, who wants to bother with prevention? Programs like the Track Your Plaque program present real potential to stop coronary heart disease in its tracks for many, if not most, participants--but don't expect to hear about it from your cardiologist. Don't expect to hear about it from the increasingly hospital-employed primary care physician.

Hopefully, media exposure like that in the New York Times is just the beginning of a public re-analysis of not only what's wrong with medicine today, but recognition of the tremendous power in preventive strategies when everyone stops being so enamored with hospital-based procedures. CT-based heart scanning that ignites your heart disease prevention program is your way to dodge the mainstream obsession with procedures.

More on "Bio-identical hormones" and Wyeth Pharmaceuticals

18. August 2006 William Davis (0)
In October 2005, Wyeth petitioned the FDA, requesting that it completely ban the bioidentical alternatives that women have been using in ever-increasing numbers to achieve optimal hormone balance. With bioidentical replacement therapy clearly reducing its market share, Wyeth asked the FDA to outlaw all compounded bioidentical hormone formulations that compete with its own discredited drugs. If Wyeth is successful, then menopausal women will have no choice other than to take potentially life-threatening hormone drugs or to forgo hormone replacement therapy altogether, thus enduring the physically and emotionally debilitating effects of menopause-induced hormone depletion.

For more commentary on Wyeth Pharmaceutical's outrageous and brazen petition to the FDA to bar prescription "bio-identical" hormones, i.e., hormones that are identical to natural human forms, read Life Extension's article, Health Freedom Under Attack!
Drugmaker Seeks to Deny Access to Bioidentical Hormones




This well-researched article is in the August, 2006 issue of Life Extension Magazine. The article can also be accessed online at http://www.lef.org/magazine/mag2006/aug2006_cover_attack_01.htm

or go to www.lef.org and click on the August, 2006 issue.

The author, Dave Tuttle, details the baseless arguments raised by Wyeth, a pathetic and amazingly selfish act in the name of protecting profits for Premarin, their prescription agent. It's bad enough to be selling this worthless drug. It's even worse--criminal, in my mind--to try to stamp out our right to have a physician write a prescription for a pharmacy to mix up hormones identical to that humans produce, individualized to our needs.

If you are as angry about this as I am, please go to the Life Extension online reprint that provides access to the International Academy of Compounding Pharmacists website to send the FDA an e-mail describing your opinion, or go to www.iacprx.org.

How accurate is LDL cholesterol?

17. August 2006 William Davis (0)
Watch TV and you'd get the impression that the world revolves around LDL cholesterol: Commercials for Lipitor, Zetia, Vytorin, etc., all drugs to reduce cholesterol (total and LDL). Your doctor looks first and often only at LDL cholesterol.

If there's so much attention paid to LDL, how accurate is it? 100%? 90%? 80%?

Well, it varies widely. Occasionally, it's truly accurate, but most of the time it's miserably inaccurate . Every single day, I see people with LDL cholesterols that underestimates true (measured) LDL by 40%, 50%, and even over 100%. In other words, LDL cholesterol might be 120 mg/dl by the conventional method, but the genuine measured value might be 160 mg/dl, or even 240 mg/dl. It can be that far off--and it's not rare.

The converse can occasionally be true, though rarely in my experience: that conventional LDL overestimates true LDL. I saw someone in the office today like this, with a conventional LDL of 142 mg/dl but a true measured LDL of 115 mg/dl. I may see one or two more people like this the rest of this year.




Why is LDL so inaccurate? Several reasons:

--LDL in most labs is calculated, not measured. The "Friedewald calculation" derives LDL by substracting HDL and triglycerides (divided by 5) from total cholesterol. The higher triglycerides are, especially above 150 mg/dl, the more inaccurate the calculation becomes. As HDL drops below 50 mg/dl, this also introduces greater and greater inaccuracy.

--LDL particles vary in size. A more accurate representation and measure of LDL's dangers are therefore found in measures of LDL particle number , rather than a weight-based measure or calculation. LDL particle number can be measure as just that, LDL particle number (NMR), or as apoprotein B, the protein in LDL that occurs one apoB per LDL.

I liken conventionally calculated LDL cholesterol to a broken speedometer. You simply won't have an accurate measure of how fast you're going, though you may have a ballpark sense. But try telling that to the state patrol.

Or, as a cardiologist colleague said to me in a similar conversation about LDL: "Well, it's better than nothing!"

The lesson: If you're interested in plaque control, and control or reduction of heart scan score, you need a measured LDL, preferably LDL particle number by NMR or an apoprotein B. Another option is "direct" LDL.

Green tea: friend or faux?

15. August 2006 William Davis (0)
The www.HealthCastle.com website is a helpful website on healthy eating that sends out a free newsletter. The content is all produced by licensed dietitions and nutritionists. Although I don't agree with everything said on the site, there's still some good information.

I'm a fan of green tea. Although I believe the effects are relatively modest (weight reduction, cholesterol reduction, anti-oxidation, etc., with theaflavin and/or green tea as a beverage,) they alerted me to the fact that the Lipton Green Tea product is one you should steer clear of. Here are their comments:



"More like Soft drink than Green Tea!With 200 calories, 13 teaspoons of added sugar and a long list of artificial ingredients, Lipton Iced Green Tea is more like a bottle of soft drink than tea, in our opinion."


The Lipton website lists the ingredients:

Water, high fructose corn syrup, citric acid, green tea, sodium hexametaphosphate, ascorbic acid (to protect flavor), honey, natural flavors, phosphoric acid, sodium benzoate (preserves freshness), potassium sorbate (preserves freshness), calcium disodium edta (to protect flavor), caramel color, tallow 5, blue1.

An 8 oz serving yields 21 grams of sugar. If you drink the full 20 oz. bottle (not hard to do!), that yields 52.5 grams of sugar! You will also notice that the second ingredient listed after water is high fructose corn syrup. This ingredient, you may recall, causes triglycerides to skyrocket, causes an insatiable sweet tooth, and is a probable contributor to obesity and diabetes.

In their defense, the Lipton people do also offer a sugar-free alternative without the excessive sweeteners and empty calories.

Do the Lipton products offer the same kind of benefits from green tea catechins (flavonoids) offered by freshly brewed teas? This product has not been formally tested by an independent lab to my knowledge, though, in general, commercially prepared and bottled teas tend to have dramatically less catechin/flavonoid content compared to brewed. (The USDA website provides access to an extraordinary collection of flavonoid food content at their USDA Database for the Flavonoid Content of Selected Foods - 2003. You'll find it at http://www.ars.usda.gov/Services/docs.htm?docid=6231.)

I think the HealthCastle people got it right: Brew your own, making sure to steep for at least 3 minutes. Alternatively, a green tea or theaflavin supplement provides many of the benefits. (Theaflavin has been used in trials at doses of 375 to 900 mg per day.) An in-depth report on green tea will be coming in a future Special Report on the www.cureality.com Membership website.

The Track Your Plaque guide to getting grotesquely overweight

15. August 2006 William Davis (0)
If you'd like to gain huge quantities of weight, here's a number of helpful tips:

1) Follow the advice of food manufacturers and eat the products they label "healthy", or "heart healthy", or "part of a nutritious breakfast" etc., like Shredded Wheat cereal, pretzels ("a low-fat snack"!), low- or non-fat salad dressings.

2) Cut your morning calorie intake by skipping breakfast.

3) Hang around with other heavy people. They will confirm that it's okay to be overweight.

4) Call walking your dog "exercise".

5) Get a sedentary desk job. Use your swivel desk chair to scoot about whenever possible, rather than getting up to do things.

6) Say "I've worked hard all week long. Weekends are for relaxing, not for physical activities. I deserve a rest."

7) Eat foods without thinking about it: Eat chips while watching football, eat while on the phone, daydream over the sink.

8) Eat to provide comfort when stressed.

9) Eat foods that have sentimental value, whether or not they're good for you: Freshly-baked cakes that remind you of Mom, Pop Tarts that you used to carry in your lunchbox when you were a kid, hot dogs just like Dad would buy at the baseball stadium.

10) Cut back on sleep and generate insatiable starch cravings.

11) Stack your shelves at home with great variety. That way, you'll always have something to suit your mood.

12) Say to your spouse: "It's none of your damn business what I eat! I'm a grown man/woman!" Prove it by over-indulging in obviously unhealthy foods.

13) Tell yourself that you're just too busy to pay attention to food choices. Just grab whatever you can out of a convenience store or vending machine.

See, it's easy! And that just a start.

Of course, I don't really want you to do any of these things. But if you see yourself in any of the above, and you're struggling with weight, you should seriously rethink your approach.

Your heart scan is just a "false positive"

15. August 2006 William Davis (0)
I've seen this happen many times. Despite the great media exposure and the growing acceptance of my colleagues, heart scans still trigger wrong advice. I had another example in the office today.

Henry got a CT heart scan in 2004. His score: 574. In his mid-50s, this placed him in the 90th percentile, with a heart attack risk of 4% per year. Henry was advised to see a cardiologist.

The cardiologist advised Henry, "Oh, that's just a 'false positive'. It's not true. You don't have any heart disease. Sometimes calcium just accumulates on the outside of the arteries and gives you these misleading tests. I wish they'd stop doing them." He then proceeded to advise Henry that he needed a nuclear stress test every two years ($4000 each time, by the way). No attempt was made to question why his heart scan score was high, since the entire process was outright dismissed as nonsense.

I'm still shocked when I hear this, despite having heard these inane responses for the past decade. Of course, Henry's heart scan was not a false positive, it was a completely true positive. I'm grateful that nothing bad happened to Henry through two years of negligence, though his heart scan score is likely around 970, given the expected, untreated rate of increase of 30%.

The cardiologist did a grave disservice to Henry: He misled him due to his ignorance and lack of understanding. I wish Henry had asked the cardiologist whether he had read any of the thousands of studies now available validating CT heart scans. I doubt he's bothered to read more than the title. The cardiologist is lucky (as is Henry) that nothing bad happened in those two years.

Do false positives occur as the cardiologist suggested? They do, but they're very rare. There's a rare phenomenon of "medial calcification" that occurs in smokers and others, but it is quite unusual. >99% of the time, coronary calcium means you have coronary plaque--even if the doctor is too poorly informed to recognize it.

What's better than a heart scan?

13. August 2006 William Davis (0)

Do you know what's better than a heart scan?

Two heart scans. No other method can provide better feedback on the results of your program.

Say you've made efforts to correct high LDL; lost weight to raise HDL and reduce small LDL; added soluble fibers, nuts, and dramatically reduced wheat products; take fish oil, vitamin D, and follow a flavonoid-rich diet. Has it worked?

After a year or so of your program, that's when another heart scan can give you invaluable feedback on whether it's been successful. I tell my patients that it's relatively easy to correct lipid and lipoprotein abnormalities. The difficult part is to know when it's good enough. Is your LDL of 67 mg/dl and HDL of 50 mg/dl good enough? Another heart scan score is the best way I know of to find out.

Variation in plaque growth differs hugely from one person to another, even at equivalent lipoprotein values. Why? Lots of reasons. Humans are inconsistent day to day. Lipoproteins, being a snapshot in time and not a cumulative value, change somewhat from day to day. There's also the possibility of unmeasured, unrecognized factors that influence coronary plaque growth. We may not be smart enough to identify these hidden factors yet. But your heart scan score will incorporate the effects of these hidden factors.

Ideally, we aim for zero growth in plaque (no change in score) or a reduction. But, particularly in the first year, 10% or less plaque growth is still a good result that predicts much reduced risk of heart attack. More than 20% per year and your program needs more work--or else you know what's ahead.

Lipids are snapshots in time; heart scans are cumulative

12. August 2006 William Davis (0)
Let me paint a picture. It's fictional, though a very real portrait of how things truly happen in life.

Michael is an unsuspecting 40-year old man. He hasn't undergone any testing: no heart scan, no lipids or lipoproteins. But we have x-ray vision, and we can see what's going on inside of him. (We can't, of course, but we're just pretending.) Average build, average lifestyle habits, nothing extraordinary about him. His lipids/lipoproteins at age 40:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

At age 40, with this panel, his heart scan score is 100. That's high for a 40-year old male.

Fast forward 10 years. Michael is now 50 years old. Michael prides himself on the fact that, over the past 10 years, he's felt fine, hasn't gained a single pound, and remains as active at 50 as he did in 40. In other words, nothing has changed except that he's 10 years older. His lipids and lipoproteins:

--LDL cholesterol 150 mg/dl
--HDL cholesterol 38 mg/dl
--Triglycerides 160 mg/dl
--Small LDL 70% of all LDL

Some of you might correctly point out that just simple aging can cause some deterioration in lipids and lipoproteins, but we're going to ignore these relatively modest issues for now.)

Lipids and lipoproteins are, therefore, unchanged. Michael's heart scan score: 1380, or an approximate 30% annual increase in score. (Since Michael didn't know about his score, he took no corrective/preventive action.)

My point: If we were to make our judgment about Michael's heart disease risk by looking at lipids or lipoproteins, they would'nt tell us where he stood with regards to heart disease risk. His lipids and lipoproteins were, in fact, the same at age 50 as they were at age 40. That's because measures of risk like this are snapshots in time.

In contrast, the heart scan score reflects the cumulative effects of life and lipids/lipoproteins up until the day you got your scan.

Which measure do you think is a better gauge of heart attack risk? I think the answer's obvious.

11. August 2006 William Davis (0)
The recognition of the metabolic syndrome as a distinct collection of factors that raise heart disease risk has been a great step forward in helping us understand many of the causes behind heart disease.

Curiously, there's not complete agreement on precisely how to define metabolic syndrome. The American Heart Association and the National Heart, Lung, and Blood Institute issued a concensus statement in 2005 that "defined" metabolic syndrome as anyone having any 3 of the 5 following signs:





Waist size 40 inches or greater in men; 35 inches or greater in women

Triglycerides 150 mg/dL or greater (or treatment for high triglycerides)

HDL-C <40 mg/dL in men; <50 mg/dL in women (or treatment for reduced HDL-C)

Blood Pressure >130 mmHg systolic; or >85 mmHg diastolic (or drug treatment for hypertension)

Glucose (fasting) >100 mg/dL (or drug treatment for elevated glucose)


Using this definition, it has become clear that meeting these criteria triple your risk of heart attack.

But can you have the risk of metabolic syndrome even without meeting the criteria? What if your waste size (male) is, 36 inches, not the 40 inches required to meet that criterion; and your triglycerides are 160, but you meet none of the other requirements?

In our experience, you certainly can carry the same risk. Why? The crude criteria developed for the primary practitioner tries to employ pedestrian, everyday measures.

We see people every day who do not meet the criteria of the metabolic syndrome yet have hidden factors that still confer the same risk. This includes small LDL; a lack of healthy large HDL despite a normal total HDL; postprandial IDL; exercise-induced high blood pressure; and inflammation. These are all associated with the metabolic syndrome, too, but they are not part of the standard definition.

I take issue in particular with the waist requirement. This one measure has, in fact, gotten lots of press lately. Some people have even claimed that waist size is the only requirement necessary to diagnose metabolic syndrome.

Our experience is that features of the metabolic syndrome can occur at any waist size, though it increases in likelihood and severity the larger the waist size. I have seen hundreds of instances in which waist size was 32-38 inches in a male, far less than 35 inches in a female, yet small LDL is wildly out of control, IDL is sky high, and C-reactive protein is markedly increased. These people obtain substantial risk from these patterns, though they don't meet the standard definition.

To me, having to meet the waist requirement for recogition of metabolic syndrome is like finally accepting that you have breast cancer when you feel the two-inch mass in your breast--it's too late.

Recognize that the standard definition when you seen it is a crude tool meant for broad consumption. You and I can do far better.

What role DHEA?

9. August 2006 William Davis (2)



DHEA, the adrenal gland hormone, has suffered its share of ups and downs over the years.

Initially, DHEA was held up as the fountain of youth with hopes of turning back the clock 20 years. Such extravagant dreams have not held up. But DHEA can still be helpful for your program.

All of us had oodles of DHEA in our bodies when we were in our 20s and 30s. Gradually diminishing levels usually reach nearly blood levels of around zero by age 70.



In our heart disease prevention program, of course, we aim to stop or reduce your CT heart scan score. Does DHEA reduce your score? No, it most certainly does not. But it can be helpful for gaining control over some of the causes behind coronary plaque.

For instance, DHEA can:

--Help reduce abdominal fat and increase muscle mass (slightly)
--Provide more physical stamina.
--Boost mood.
--It may modestly reduce some of the phenomena associated with the metabolic syndrome (high blood pressure, high blood sugar, high insulin, low HDL, small LDL, etc.)

In my experience, people who feel better do better on their overall program. If you're always tired and run down and run out of steam by 3 pm, I won't see you riding your bicycle outdoors or at the aerobics class. But if you're bursting with energy until you put your head on the pillow, you're more inclined to walk, bike, dance, play with the kids, dance, take Tai Chi, etc.

Some downsides to DHEA: Some people experience aggression. Backing off on the dose usually relieves it. Also, sleeplessness. Taking your DHEA in the morning usually fixes it.



The dose is best tailored to your age and blood levels. People less than 40 years old should not take DHEA. The older you are, the higher the dose, though we rarely ever have to exceed 50 mg per day. If you've never had a blood level and your doctor refuses to obtain one, 25 mg per day is a reasonable dose (10-15 mg in women 40-50 years old). It's always best to discuss your supplement use, particularly agents like DHEA, with your doctor.

Grasscutting, fertilizer, and healthcare

25. August 2009 William Davis (23)
A guy named Jeff, a 60-something, taciturn, "How 'bout dem Brewers?" kind of guy, cuts my grass.

Once a week, Jeff drives over his rust-rimmed 1994 Chevy pickup and trailer, unloads his ride mower, and cuts the grass. For his 40 minutes of work, I pay him $35.

For $35, all he does is cut the grass--no trimming, no picking up debris, no working in the garden, no fertilizing, no weeding. Just cutting the grass. Occasionally, Jeff has proven to be a useful resource for peculiar problems. Last year, I had a drainage problem that he helped solve and two years ago he helped diagnose a tree disease that was killing a tree in the backyard; it's now recovered.

To save money, and because I like to work in the yard, I do the rest. I trim the edges, I fertilize the grass, plant new flowers and trees, fix damaged areas, trim wild branches.

In my view, my relationship with Jeff, a limited, as-needed relationship, in which I ask him to help with specific issues but I manage the rest myself, is how I believe that healthcare should also be conducted.

Your doctor should be like Jeff: Perhaps not taciturn, but an as-needed resource available while you do much of the work.

My simple relationship with Jeff is, I believe, the healthcare model of the future. You manage your own cholesterol issues, your own basic thyroid issues, supplement and monitor your vitamin D levels, use diet to suit your needs, order blood tests when necessary, even obtain basic imaging tests like heart scans, carotid ultrasound, bone density testing. Your doctor is a resource, near by when and if you need him or her: guidance when needed, an occasional review of what you are doing, someone to consult when you fracture an ankle.

What your doctor is NOT is a paternal, "do what I say, I'm the doctor," or a "You need these tests whether you like it or not" holder of your health fate.

It is a model of healthcare that will evolve over the next 20-30 years, only in its infancy now.

While we started Track Your Plaque as just a resource for in-depth information on prevention and reversal of coronary heart disease, I now see it as something much greater: a prototype for the emerging concept of self-directed health.

Enough for now. I've got some tomatoes to pick.

Iodine deficiency is REAL

21. August 2009 William Davis (30)
Like many health-conscious people, Kurt avoids salt. In fact, he has assiduously avoided salt ever since his heart attack back in 1995.

Lately, Kurt had become tired, often for little or no reason. His thyroid panel:

TSH 4.2 mIU/L (0.27-4.20)
Free T3 1.74 pg/ml (2.50-4.30)
Free T4 1.05 ng/dl (0.9-1.7)

Kurt's TSH of 4.2 mIU/L is sufficient to increase LDL cholesterol by 20-30% and increase the (relative) risk for heart attack 3-fold.

Kurt's thyroid was also palpably enlarged. While it was just barely visible--just a minor bulge in the neck (in the shape of a bowtie), it could be clearly felt when I examined him.

I asked Kurt to add 500 mcg of iodine every day. Three months later, another thyroid panel showed:

TSH 0.14 mIU/L (0.27-4.20)
Free T3 2.50 pg/ml (2.50-4.30)
Free T4 1.1 ng/dl (0.9-1.7)

Kurt's thyroid function normalized to nearly ideal levels just with iodine replacement. (The free T3, while improved, remains low; an issue for another day!)

I see this response with some frequency: low-grade goiter and apparent hypothyroidism (low thyroid function) that responds, at least partially, to iodine replacement. In Kurt's case, iodine replacement alone normalized his thyroid measures completely.

With improved thyroid measures, Kurt also felt better with renewed energy and a 22 mg/dl reduction in LDL cholesterol.

Make no mistake: Iodine deficiency is real. While most of my colleagues have dismissed iodine deficiency as a relic of the early 20th century and third world countries, you can also find it in your neighborhood.

Fish oil for $780 per bottle

19. August 2009 William Davis (16)
At prevailing pharmacy prices, one capsule of prescription Lovaza fish oil costs $4.33 each.

Yes, you heard right: $4.33 per capsule.

What do you get for $4.33 per capsule? By omega-3 fatty acid content, you get 842 mg EPA + DHA per capsule.

I can also go to Sam's Club and buy a bottle of their Triple-Strength fish oil with 900 mg omega-3 fatty acids per capsule at $18.99 per bottle of 180 capsules. That comes to 10.5 cents per capsule. That puts the price of fish oil from Sam's Club at 97.6% less cost compared to Lovaza for an equivalent quantity of omega-3 fatty acids.

What if we repriced Sam's Club's Triple-Strength and brought it "in line" with what we pay for Lovaza? That would put the value of one bottle of Sam's Club Triple-Strength fish oil at $780 per bottle.

I take patients off Lovaza every chance I get.

Organic really IS better

16. August 2009 William Davis (18)
If you have any doubts about the value of organic foods vs. conventionally-grown foods, then take a look at the findings from a USDA--Yes, USDA--sponsored study.

In this study, the nutritional content of organic vs. conventionally-grown blueberries were compared. Ironically, these observations come from the USDA's Genetic Improvement of Fruits and Vegetables Laboratory of the Produce Quality and Safety Laboratory.

Their findings (all values expressed as weight per 100 grams fresh weight blueberries, or a bit less than 1/4 cup):


Total phenol content (e.g, flavonoids):

Organic: 319.3 mg
Conventional: 190.3 mg

Organic blueberries had 68% greater phenol content.


Total anthocyanins (an important class of flavonoids):

Organic: 131.2 mg
Conventional: 82.4 mg

Organic blueberries had 59% greater anthocyanin content.


Antioxidant capacity (ORAC):

Organic: 46.14 mg
Conventional: 30.8

Organic blueberries had 50% greater antioxidant capacity.


Flavonoids suspected to carry unusually potent health effects--malvidin, delphinidin, myricetin, and quercetin--were all contained in greater proportions in the organically-grown blueberries, also. These flavonoids are demonstrating pharmacologic-level health effects in preliminary studies.

Why a genetics laboratory? After all , the study findings came out heavily in favor of non-genetic, organic farming methods of growing produce. It certainly must have at least given pause to the vocal group within agriculture and the USDA that have long argued that organic produce is no different. I suspect that the laboratory will now try to recreate the nutritional value of organic through genetic manipulation of cultivars grown using conventional methods.

Regardless of the motivations behind the study, we see that there is no comparison: organic blueberries are superior in nutritional value to those grown with conventional pesticides and herbicides. While the study addressed only blueberries, the dramatic difference makes it likely that similar differences exist in other fruits and vegetables.

Coming on the Track Your Plaque website: An in-depth Special Report on the health effects of anthocyanins.

Do you really need calcium?

12. August 2009 William Davis (0)
Why are we advised to take calcium supplements?

Men and women are advised to take calcium because it has been shown to reduce blood pressure modestly. Women, in particular, can stall the deterioration of bone strength (mineralization) by taking calcium supplements, 1200-1300 mg per day, and eating calcium-rich foods like dairy products.

Is that all true?

It is true insofar as we remain vitamin D deficient. A funny thing happens when you fully replete vitamin D: Intestinal absorption of calcium as much as quadruples. That means your body will efficiently absorb the calcium in broccoli and spinach.

Is it still necessary to force-feed your body megadoses of calcium once vitamin D has been repleted? I don’t think so.

While the evidence is indirect, several observations point towards the lack of necessity of calcium once vitamin D is addressed.
For instance:

Women who take calcium, 1200 mg per day, with vitamin D, 800 units per day, double their five-year risk for heart attack, according to a New Zealand study.

Men who take calcium, 1200 mg per day, with vitamin D, 800 units per day, also may substantially increase heart attack risk.

Bone density increases more with vitamin D than with calcium. Calcium may not even be necessary to increase bone mineralization, since there are data to suggest that vitamin D can accomplish this by itself.

Calcium suppresses parathyroid hormone, PTH. That is, in fact, how calcium stalls (usually does not reverse) bone mineral loss-not by adding calcium to bone, but by suppressing PTH release. (PTH causes bone demineralization.) Vitamin D suppresses PTH to a far greater degree than calcium.

What is needed is a broad reconsideration of the advice everyone is getting to take calcium. In an age when more and more people are appreciating the power of vitamin D supplementation to achieve normal blood levels, there may be danger ahead for those who fail to address their calcium overdosing.

The case against vitamin D2

11. August 2009 William Davis (40)
Why would vitamin D be prescribed when vitamin D3 is available over-the-counter?

Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol):

--D3 is the human form; D2 is the non-human form found in plants.

--Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998).

--D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004).

--D2 has lower binding affinity for vitamin D-binding protein, compared to D3

--Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2.

--As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon (Harris SS et al 2002).




From Armas LA, Hollis BW, Heaney RP 2004


While there are dissenters on this view, the bulk of evidence suggests that D2 is an inferior form of D3.

Then why is D2 prescribed by many doctors when the natural, human, and superior D3 is available over-the-counter?

You already know the answer: Much of your doctor's education did not come from scientific lectures nor from reading scientific studies. It came from the pretty drug representative in the waiting room who hands the doctor reprints of the "studies" performed by the drug industry to support the use of their drugs. There is no such nutritional supplement representative in the waiting room. This preference for the "drug" D2 over the supplement D3 also stems from the inherent preference of physicians for things they can control, whether or not there is proof of superiority.

In my view, there is absolutely no reason to take vitamin D2 over D3 except to enrich the drug industry.

Honey: More fructose than high-fructose corn syrup

11. August 2009 William Davis (21)
Honey: It’s natural. Mom probably gave it to you, either straight or in tea for a sore throat when you were a kid. Even today, honey is touted as possessing almost supernatural qualities for promoting health.

Honey contains B vitamins, minerals, and a handful of antioxidants. It also contains . . . fructose. 60% of honey, in fact, is fructose.

While the average per capita intake of honey is only a modest 1.29 lb per year (National Honey Board; 2008) and therefore contributes only 0.77 lb of fructose per year, there are people who, believing honey to be healthy, use it to excess and use far more than 1.29 lb per year.

How does that compare to table sugar, or sucrose?

Sucrose is 50:50 glucose to fructose. How about high-fructose corn syrup, the sweetener found in virtually all processed foods that has replaced sucrose as the most common sweetener? Depending on the variety, high-fructose corn syrup is generally 42-55% fructose. Many of us (including me) believe that the proliferation of high-fructose corn syrup in processed foods is a big part of the reason Americans are fat and diabetic.

Yes: Judged by its fructose content, honey is worse than high-fructose corn syrup. It is also worse than sucrose.

It means that honey can also contribute to the adverse health effects of fructose, as detailed in this prior Heart Scan Blog post.

Sun, fish, and seaweed

8. August 2009 William Davis (9)
Extraordinary heart health springs from three basic sources in our environment:

Sun, fish, and seaweed.

Sun: Sunlight exposure is nature's intended source of vitamin D. Humans were meant to run naked, or at least scantily clad, in tropical or sub-tropical climates. The large surface area of skin ensured plenty of skin activation of vitamin D, along with long days of intense sun (unlike the seasonal variation of day length and less intense sun further north).

Fish: Fish are the principal source of omega-3 fatty acids, as are, to a lesser degree, wild land animals. Humans as hunter-gatherers tracked, captured, and slaughtered fish and wild game, eaten immediately, since there was no means of storage. Omega-3-rich game was the principal source of fat for primitive cultures.

Seaweed: Seaweed is the world’s most concentrated source of iodine. While seafood like fish and shellfish also contain iodine, seaweed contains, on average, a thousand-fold greater quantity. Seaweed, like plants found on land, are also rich in phytonutrients.

The healthiest cultures on earth follow this simple recipe for health. The unhealthiest population on earth-meaning Americans (i.e., without benefit of bail-out medications and procedures that keep us alive, or vaccinations that protect us from infectious diseases)--neglect all three. Witness the Okinawans, whose daily meals nearly always contain some form of fish and seaweed, and whose sub-tropical climate provides greater sun exposure. It is not unusual for Okinawans to live to 100 years of age, not as an exception, but the rule. Heart disease was virtually unknown except in 90-year olds and older-that is, until the recent adoption of Western practices like fast food and snacks.

It's pretty incredible when you think about it: Simple practices can markedly reduce your likelihood of heart attack and developing heart disease.

Perhaps you’d rather not run naked along a semi-tropical beach, spear fish, and gather seaweed. You could always do the modern equivalents and achieve similar benefits.

Fructose is a coronary risk factor

4. August 2009 William Davis (21)
As discussed in a previous Heart Scan Blog post, Say Goodbye to Fructose, a carefully-conducted University of California study demonstrated that, compared to glucose, fructose induces:

1) Four-fold greater intra-abdominal fat accumulation

2) 13.9% increase in LDL cholesterol, doubled Apoprotein B

3) 44.9% increase in small LDL, 3-fold more than glucose

4) Increased postprandial triglycerides 99.2%.


Other studies have shown that fructose:

--Increases uric acid--No longer is red meat the cause for increased uric acid; fructose has taken its place. Uric acid may act as an independent coronary risk factor and increases high blood pressure and kidney disease.

--Induces insulin resistance, the situation that creates diabetes

--Increases glycation (fructose linked to proteins) and protein cross-linking, processes that underlie atherosclerosis, liver disease, and cataracts.


Make no mistake: Fructose is a powerful coronary risk factor.
There is no doubt whatsoever that a diet rich in fructose from fruit drinks, honey, raisins and other dried fruit like cranberries, sucrose (table sugar), and high-fructose corn syrup is a high-risk path to heart disease.

Also note that many foods labeled "heart healthy" because of low-fat, low saturated fat, addition of sterol esters, or fiber, also contain fructose sources, especially high-fructose corn syrup.
