How many ways can you disguise sugar?

28. July 2006 William Davis (0)
I came across this shockingly silly report on AOL, who obtained their info courtesy Health Magazine:

The Best New Healthy Foods for Busy People
from Health

The foods on their list:

Kettle Brand Bakes Hickory Honey BBQ--the healthy claim is based on the lack of trans-fatty acids and low-fat.










Post Healthy Classics Raisin Bran Cereal Bars, Cranberry--Likewise, low-fat, sweet, and addictive means healthy to these people.




Amy’s Mediterranean Pizza With Cornmeal Crust --Please!!



Horizon Organic Colby Cheese Sticks --Because it's made by cattle without use of growth hormone or antibiotics, they declare this healthy. I guess we can ignore the saturated fat content and high total fat content.

100% Whole Grain Chips Ahoy! Cookies --You mean we can add the bran back to wheat products and make it healthy?!


This kind of mass-market marketing trickery leaves me incredulous. Don't believe it for a moment. This is typical of the food industry: Take one aspect of nutrition that is truly healthy, such as high-fiber, or low-fat, or organic. Then add undesirable, unhealthy ingredients. The current fad is to add lots of sugar and or sugar-equivalents (usually flour and other wheat products). Because there's one healthy ingredient, they'll call the end-product healthy, too.

If you want to see what health looks like if you indulge in "healthy" products like this, just look up and down the grocery aisles at your neighborhood grocery store. You're likely to see the results: Gross obesity, diabetes, and arthritis.

You won't, of course, see the huge acceleration of growth in coronary plaque, but it's there, ticking away.

Let's gamble with your health

Let's gamble with your health

Let's play a game.

I'm going to list some lipid patterns and you tell me whether or not the person with these values has heart disease.

Patient 1

Total cholesterol 150 mg/dl
LDL cholesterol 75 mg/dl
HDL 50 mg/dl
Triglycerides 125 mg/dl


Patient 2

Total cholesterol 300 mg/dl
LDL cholesterol 200 mg/dl
HDL cholesterol 35 mg/dl
Triglycerides 325


Patient 3

Total cholesterol 300 mg/dl
LDL cholesterol 100 mg/dl
HDL cholesterol 25 mg/dl
Triglycerides 875 mg/dl



Let's say that any one of these profiles is yours. Should you be getting your affairs in order, preparing for your cardiac catastrophe? Should you demand a stress test from your doctor, hoping that it will shed some light on your dilemma? Should you go ahead and go to the all-you-can-eat rib restaurant, content that you will be attending your granddaughger's wedding in 2020 in full health?

If you can tell, you're a lot better at this than I am.

I provide consultation to other physicians and patients on complex hyperlipidemias in my area. In other words, if someone has a difficulty to manage lipid disorder, the doctor sends the patient to me.

Managing these wildly variable values is the easy part. Deciding whether or not heart disease is concealed within the patient . . . well, that's the hard part.

Let's take it a step further: Suppose all three profiles also have 50% of all LDL particles as the abnormal small particles. And they all have a lipoprotein(a) level of 50 mg/dl, an abnormally high level.

How about now: Can you tell whether any or all of these people have hidden heart disease?

What if they are 20 years old? Does that make a difference?

What if they are all females over 65 years--how about now?

If the only tool you have to divine the presence of hidden heart disease is a lipid panel, or even a lipoprotein panel, then the best you can manage is to hazard a guess based on statistical probability. You also assume that this "snapshot" represents the sorts of values someone has had for their entire lives. You cannot factor in the fact that the first person gained 60 lbs in the last three years since completing menopause. You can't factor in that patient 2 smoked two packs of cigarettes a day for 25 years, but quit 10 years ago.

It's also foolhardy to believe that every known cause of heart disease is currently identifiable and revealed by modern-day blood testing.

A heart scan is simply a means to quantify the sum-total of risk factors--causes--that have exerted an effect up until the moment of your scan. It will reveal the quantity of coronary atherosclerotic plaque present, regardless of whether you stopped smoking 20 years ago or lost 30 lbs last year.

For these reasons, nothing can replace the value of quantifying plaque: not cholesterol, not the Framingham risk calculation, not measures of small LDL or lipoprotein(a), not the presence or absence of symptoms. In 2008, the method of choice for measuring plaque remains a CT heart scan. Perhaps in 10 years it will be some other method.

As always, let me remind Heart Scan Blog viewers that I make this point NOT to sell heart scans, which I have no reason whatsoever to do. I say this because we require a tool to track this potentially fatal disease. We require a yardstick for tracking progression or regression. The only tool that suits these purposes in 2008 is a CT heart scan.

    An EBT heart scan is also acceptabte, or equivalent to a CT scan?

    So, Dr. Davis. Do you ever use carotid intimal medial thickness measurements in your practice? If so, how?  If not, why not?

    instead of having to be exposed to radiation of a heart scan why wouln't a carotid IMT study be enought to indicate CAD since a narrowing of the carotid would preesent a high probability of CAD?

    Well we are going to do the heart scan in Feb - thanks to your blog.
    Check this out, our local place that does it is offering a two for one price! So me and the hubby can both get it done. I am nervous a bit but ready to do it.

Cholesterol follies

Cholesterol follies

11. January 2008 William Davis (5)
Rudy is a 59-year old man. He's had three heart catheterizations, two of which resulted in stent implantations. Obviously, Rudy should be the beneciary of a prevention program.

His basic cholesterol values:

Total cholesterol 164 mg/dl--pretty good, it seems.

LDL cholesterol 111 mg/dl--Wow! Not too bad.

HDL cholesterol 23 mg/dl--Uh oh, that's not too good.

Triglycerides 148 mg/dl--By national (NCEP ATP-III) guidelines, triglycerides of 150 mg/dl and below fall within the desirable range.


So we're left with an apparently isolated low HDL cholesterol, nothing more. On the surface, it doesn't seem all that bad.

Of course, we need to keep in mind that this pattern landed Rudy in the hospital on several occasions and prompted several procedures.

Should we rely on these results? How about Rudy's lipoproteins?

Here they are (NMR; Liposcience):

LDL particle number 2139 nmol/l--Representing an effective LDL of 213--over 100 mg higher than the standard value (above) suggests.

Small LDL particles 2139 nmol/l--In other words, 100% of all Rudy's LDL particles are small. (Thus, weight-based measures of LDL cholesterol fail to tell us that he has too many small particles.)

Large HDL 0 (zero) mg/dl--Rudy has virtually no functional HDL particles.


If we had relied only on Rudy's standard cholesterol values, we would have focused on raising HDL. However, lipoprotein analysis uncovered a smorgasbord of additional severe patterns. The high LDL particle number comprised 100% of small particles is especially concerning.

Truly, conventional cholesterol testing is a fool's game, one that time and again fails to fully uncover or predict risk for heart disease. One look at Rudy's lipoproteins and it becomes immediately obvious: This man is at high risk for heart disease and the causes are clear.

Of course, many physicians and insurance companies argue that the added information provided by this portion of the lipoprotein test added around $70 more to the expense.

When you see results like this, is there even a choice?

    It's this type of analysis that's most instructive and most interesting. If I were 20 years younger reading this post, I'm confident I'd have avoided open    heart surgery I went through this past April.

    I couldn't find another place to give you general feedback, so it goes here:  thanks for what you do.  

    I've been an insulin dependent diabetic for 6 years now with a family history of CAD.  While I have moderately good scores (59 for HDL, triglycerides below 60), I've been concerned about getting a better picture.

    I had a CT Heart Scan Wednesday, which resulted in a wonderful 0 reading.  While I plan to push my family practitioner for NMR tests in the future, it's nice to get some validation now.  At $125, the price was a major bargain, as well.

    Again, thanks for sharing what you know.

    Well, then, more to come!

    Interestingly, given a LDL particle count of 2139, Rudy would have been better off with a LARGER standard LDL cholesterol value, as this would imply his particles were larger and hence less atherogenic.

    Yes, ironically.
