Condition Afflicts Millions: Do you have “YBS”?

12. May 2014 Lisa G Nutrition (0)
After one of the harshest winters, spring has finally arrived.  The welcomed warmer temperatures and longer daylight hours infuse us with a sense of renewal and new beginnings.   Low and behold we begin to come out of hibernation and start the mad dash to engage in positive lifestyle changes such as eating better, exercising, proper sleep and taking appropriate nutritional supplements.  But invariably, life happens.  

Yep, just when you were about to get started, it happens.  YBS sets in.   I see this “condition” all too often with clients attempting to enter or re-enter into any number of behavior changes.  I will go so far as to say we all have been afflicted at one point or another in our lives.  I call this condition Yeah But Syndrome, or “YBS”.    It is often paralyzing and prevents those afflicted from moving into action, instead remaining in a state of inertia.  

There are many symptoms of YBS but the following are some of the most common.  

• Yeah I planned to go to the gym today BUT, the kids needed a ride to practice.  
• Yeah I really want to eat better BUT I don’t have the time.   
• Yeah I didn’t plan to eat the cake BUT my husband wanted too, so I did also.   
• Yeah I really meant to go to the grocery shopping BUT I was too tired, so I hit the drive- thru.  
• Or this is a good one. Yeah I meant to start today BUT, I’ll start tomorrow.  

But tomorrow never comes.  You get the drift.  We can all come up with a million yeah buts, in other words, excuses.    The good news is the treatment for YBS is simple--just do it!  Take action.  The reality of today’s 24-7 planet is there will always be something.  The kids, work commitments, family obligations and various projects that need your attention will perpetually be present in some shape or form.  The difference to make the difference is to learn to dance in the rain, not wait for the rain to pass.  When will all the stars align so that your world will be “just right” to start?  If not NOW, WHEN will you begin?  

The key word here is begin.   Far too frequently, I coach clients that shoot themselves in the foot before they start.   Instead of consuming yourself with all the barriers to entry, select reasonable, low-hanging fruit that is “doable.”    The art of lifestyle change is to avoid all-or-nothing thinking and begin to appreciate what you CAN do, versus focusing energy on what you can’t do.  What is one action you can do TODAY to move toward your wellness goal(s)?  Start to focus on what you can do in the mist of your existing life demands. This mantra is a friendly reminder: BE-DO-HAVE.  Be committed.  Do what it takes.  And you will have results.  

Lastly, if you think removing cereal from your morning routine it is too difficult and you can’t do it. Guess what-- you’re likely right.   What you think is what you get!   But what if you think instead, “I can do this.  There are many truly healthy options for breakfast to replace cereal such as eggs and veggies that will help me look and feel my best.”  Then guess what--you will!  This simple change in mind-set can start a tidal wave of change and prevent you from abandoning ship when life tosses you into rough waters.  Ongoing support is hugely important to sustain lifestyle changes.  Join the conversations in the Cureality Forum to engage the support of health coaches and Cureality Members to stay on track. 

We Need More.....Kettlebell

8. May 2014 Amber B Exercise (0)
You either love them or you hate them.

When you are in love with kettlebells, like I am, you enjoy the multi-muscle group movements.  Kettlebell workouts are fluid, like a dance, putting together a chain of movements that leave your heart pounding and sweat pouring.  Yes, there’s some sneaky cardio component to a kettlebell workout.   A great blend of aerobic and anaerobic conditioning.

If you hate kettlebells it’s because kettlebell exercises keep you honest with proper exercise execution.  Form is imperative to moves like the kettlebell swing or the kettlebell snatch.  Do it incorrectly and you’ll be either sore or have bruised wrists the next day.  But this is no reason to shy away from the kettlebell.  You have way too much to gain from this odd looking piece of exercise equipment.  

You will get a mega -caloric burn.  The American council on Exercise states that the average kettlebell workout burns 20 calories per minute.  That’s 1200 calories in just one hour.   Kettlebell workouts utilize many muscle groups to give you an efficient, total body conditioning workout.  

If you’re looking for a toned back side get a kettlebell.  The classic kettlebell swing works all the posterior muscles like your glutes, hamstrings, and lower back.  But only if you use correct form.  Otherwise you'll find yourself with nagging back pain, instead of a better butt.  

Kettlebell exercises are functional movements that will allow you to play hard without getting injured.  If you are an athlete, a nature enthusiast, or just want to keep up with the kids then you need to give kettlebells a try.  During a workout, the exercises will target movements that will make getting up and down off the floor easier, as well as bending over to pick something up.

If you are interested in doing kettlebell workouts start with a coach or take class.  You can’t fake form with kettlebell exercises or you could end up hurt.  I’m not trying to scare anyone away because good form is easy to learn.   Your body will memorize the correct movement pattern and you’ll be on your way to a successful kettlebell workout.  

Thyroid and the gut: Hidden health partners

8. May 2014 Chris K Thyroid (0)
Though I have personally dealt with both auto-immune thyroiditis (Hashomoto’s) and several gut issues (wheat sensitivity, gastritis, etc.), it was not until recently that I discovered how close the thyroid and gut work together to keep you healthy – and how problems with one can affect the other along with your overall health.
 
Most of us understand that the primary function of the gut, that 25 to 30 feet of “tubing” that includes everything from your stomach to your large intestines, is to process the food we eat and allow the “good stuff” (essential nutrients) to pass into our blood stream while keeping the “bad stuff” (harmful proteins) out. However, it may surprise some that the gut also holds as much as 70% of all the immune tissue in the body.
 
Now, imagine all the health havoc that could ensue if, suddenly, the gut stopped doing its job – particularly if it failed to stop toxic proteins from entering the blood stream and then mounted an overzealous immune response against them.  Sometimes, those overzealous immune responses reach beyond their intended targets to attack otherwise healthy tissues and organs – like the thyroid gland.
 
Recent studies indicate that thyroid hormones play a significant role in maintaining gut integrity, preventing leaky gut that can, in some cases, lead to auto-immune attacks against the thyroid.  A properly functioning gut also aids the production of thyroid hormones by converting some of the inactive “T4” thyroid hormone into the functional “T3” hormone.  Failure to simultaneously maintain both a healthy gut and a healthy thyroid can create a vicious cycle leading to chronic health problems and declining vitality.
 
What it all means is that to enjoy optimal health, you must promote good thyroid health to promote good gut health and vice versa.  Unfortunately, traditional medicine tends to focus on one issue to the exclusion of others.  A typical endocrinologist may treat your under active thyroid without spending a moment to address underlying gut issues.  A gastroenterologist will work alleviate a gut problem but will rarely address a potential thyroid problem.
 
This illustrates, once again, how our bodies work as a system and why it is necessary to bridge the “healthcare gaps” in traditional medicine by becoming personally responsible for your health.  I encourage everyone to consult the Cureality Program Guide and online Cureality Diet and Thyroid Health Tracks to learn more about how to optimize both your gut and thyroid health on your journey to realizing complete, whole-body health.

Omega-3 fatty acids likely NOT associated with prostate cancer

18. July 2013 William Davis Omega-3 fatty acids (6)
A weakly constructed study was reported recently that purportedly associated higher levels of omega-3 fatty acid blood levels and prostate cancer. See this CBS News report, for instance.

Lipid and omega-3 fat expert, Dr. William Harris, posted this concise critique of the study, exposing some fundamental problems:

First, the reported EPA+DHA level in the plasma phospholipids in this study was 3.62% in the no-cancer control group, 3.66% in the total cancer group, 3.67% in the low grade cancer group, and 3.74% in the high-grade group. These differences between cases and controls are very small and would have no meaning clinically as they are within the normal variation. Based on experiments in our lab, the lowest quartile would correspond to an HS-Omega-3 Index of <3.16% and the highest to an Index of >4.77%). These values are obviously low, and virtually none of the subjects was in “danger” of having an HS-Omega-3 Index of >8%. So to conclude that regular consumption of 2 oily fish meals a week or taking fish oil supplements (both of which would result in an Index above the observed range) would increase risk for prostate cancer is extrapolating beyond the data.

This study did not test the question of whether giving fish oil supplements (or eating more oily fish) increased PC risk; it looked only a blood levels of omega-3 which are determined by intake, other dietary factors, metabolism and genetics.

The authors also failed to present the fuller story taught by the literature. The same team reported in 2010 that the use of fish oil supplements was not associated with any increased risk for prostate cancer. A 2010 meta-analysis of fish consumption and prostate cancer reported a reduction in late stage or fatal cancer among cohort studies, but no overall relationship between prostate cancer and fish intake. Terry et al. in 2001 reported higher fish intake was associated with lower risk for prostate cancer incidence and death, and Leitzmann et al. in 2004 reported similar findings. Higher intakes of canned, preserved fish were reported to be associated with reduced risk for prostate cancer. Epstein et al found that a higher omega-3 fatty acid intake predicted better survival for men who already had prostate cancer, and increased fish intake was associated with a 63% reduction in risk for aggressive prostate cancer in a case-control study by Fradet et al). So there is considerable evidence actually FAVORING an increase in fish intake for prostate cancer risk reduction.

Another piece of the picture is to compare prostate cancer rates in Japan vs the US. Here is a quote from the World Foundation of Urology:

"[Prostate cancer] incidence is really high in North America and Northern Europe (e.g., 63 X 100,000 white men and 102 X 100,000 Afro-Americans in the United States), but very low in Asia (e.g., 10 X 100,000 men in Japan).”

Since the Japanese typically eat about 8x more omega-3 fatty acids than Americans do and their
blood levels are twice as high, you’d think their prostate cancer risk would be much higher...
but the opposite is the case.

Omega-3 fatty acids are physiologically necessary, normalizing multiple metabolic phenomena including augmentation of parasympathetic tone, reductions of postprandial (after-meal) lipoprotein excursions, and endothelial function. It would indeed make no sense that nutrients that are necessary for life and health exert an adverse effect such as prostate cancer at such low blood levels. (Recall that an omega-3 RBC index of 6.0% or greater is associated with reduced potential for sudden cardiac death.)

I personally take 3600 mg per day of EPA + DHA in highly-purified, non-oxidized triglyceride form (Ascenta Nutrasea liquid) that yields an RBC omega-3 index of just over 10%, the level that I believe the overwhelming bulk of data suggest is the ideal level for humans.

Are statins and omega-3s incompatible?

18. June 2013 William Davis (4)
French researcher, Dr. Michel de Lorgeril, has been in the forefront of thinking and research into nutritional issues, including the Mediterranean Diet, the French Paradox, and the role of fat intake in cardiovascular health. In a recent review entitled Recent findings on the health effects of omega-3 fatty acids and statins, and their interactions: do statins inhibit omega-3?, he explores the question of whether statin drugs are, in effect, incompatible with omega-3 fatty acids.

Dr. Lorgeril makes several arguments:

1) Earlier studies, such as GISSI-Prevenzione, demonstrated reduction in cardiovascular events with omega-3 fatty acid supplementation, consistent with the biological and physiological benefits observed in animals, experimental preparations, and epidemiologic observations in free-living populations.

2) More recent studies (and meta-analyses) examining the effects of omega-3 fatty acids have failed to demonstrate cardiovascular benefit showing, at most, non-significant trends towards benefit.

He points out that the more recent studies were conducted post-GISSI and after agencies like the American Heart Association's advised people to consume more fish, which prompted broad increases in omega-3 intake. The populations studied therefore had increased intake of omega-3 fatty acids at the start of the studies, verified by higher levels of omega-3 RBC levels in participants.

In addition, he raises the provocative idea that the benefits of omega-3 fatty acids appear to be confined to those not taking statin agents, as suggested, for instance, in the Alpha Omega Trial. He speculates that the potential for statins to ablate the benefits of omega-3s (and vice versa) might be based on several phenomena:

--Statins increase arachidonic acid content of cell membranes, a potentially inflammatory omega-6 fatty acid that competes with omega-3 fatty acids. (Insulin provocation and greater linoleic acid/omega-6 oils do likewise.)
--Statins induce impaired mitochondrial function, while omega-3s improve mitochondrial function. (Impaired mitochondrial function is evidenced, for instance, by reduced coenzyme Q10 levels, with partial relief from muscle weakness and discomfort by supplementing coenzyme Q10.)
--Statins commonly provoke muscle weakness and discomfort which can, in turn, lead to reduced levels of physical activity and increased resistance to insulin. (Thus the recently reported increases in diabetes with statin drug use.)

Are the physiologic effects of omega-3 fatty acids, present and necessary for health, at odds with the non-physiologic effects of statin drugs?

I fear we don't have sufficient data to come to firm conclusions yet, but my perception is that the case against statins is building. Yes, they have benefits in specific subsets of people (none in others), but the notion that everybody needs a statin drug is, I believe, not only dead wrong, but may have effects that are distinctly negative. And I believe that the arguments in favor of omega-3 fatty acid supplementation, EPA and DHA (and perhaps DPA), make better sense.



DHA: the crucial omega-3

22. May 2013 William Davis (5)
Of the two omega-3 fatty acids that are best explored, EPA and DHA, it is likely DHA that exerts the most blood pressure- and heart rate-reducing effects. Here are the data of Mori et al in which 4000 mg of olive oil, purified EPA only, or purified DHA only were administered over 6 weeks:



□ indicates baseline SBP; ▪, postintervention SBP; ○, baseline DBP; •, postintervention DBP; ⋄, baseline HR; and ♦, postintervention HR.

In this group of 56 overweight men with normal starting blood pressures, only DHA reduced systolic BP by 5.8 mmHg, diastolic by 3.3 mmHg.

While each omega-3 fatty acid has important effects, it may be DHA that has an outsized benefit. So how can you get more DHA? Well, this observation from Schuchardt et al is important:

DHA in the triglyceride and phospholipid forms are 3-fold better absorbed, as compared to the ethyl ester form (compared by area-under-the-curve). In other words, fish oil that has been reconstituted to the naturally-occurring triglyceride form (i.e., the form found in fresh fish) provides 3-fold greater blood levels of DHA than the more common ethyl ester form found in most capsules. (The phospholipid form of DHA found in krill is also well-absorbed, but occurs in such small quantities that it is not a practical means of obtaining omega-3 fatty acids, putting aside the astaxanthin issue.)

So if the superior health effects of DHA are desired in a form that is absorbed, the ideal way to do this is either to eat fish or to supplement fish oil in the triglyceride, not ethyl ester, form. The most common and popular forms of fish oil sold are ethyl esters, including Sam's Club Triple-Strength, Costco, Nature Made, Nature's Bounty, as well as prescription Lovaza. (That's right: prescription fish oil, from this and several other perspectives, is an inferior product.)

What sources of triglyceride fish oil with greater DHA content/absorption are available to us? My favorites are, in this order:

Ascenta NutraSea
CEO and founder, Marc St. Onge, is a friend. Having visited his production facility in Nova Scotia, I was impressed with the meticulous methods of preparation. At every step of the way, every effort was made to limit any potential oxidation, including packaging in a vacuum environment. The Ascenta line of triglyceride fish oils are also richer in DHA content. Their NutraSea High DHA liquid, for instance, contains 500 mg EPA and 1000 mg DHA per teaspoon, a 1:2 EPA:DHA ratio, rather than the more typical 3:2 EPA:DHA ratio of ethyl ester forms.

Pharmax (now Seroyal) also has a fine product with a 1.4:1 EPA:DHA ratio.

Nordic Naturals has a fine liquid triglyceride product, though it is 2:1 EPA:DHA.





Krill oil: Do the math

21. May 2013 William Davis (0)
The manufacturers of krill oil claim that the phospholipid form of omega-3 fatty acids, EPA and DHA, enhance their absorption. There are indeed some data to that effect:


Here are some representative krill oil preparations available on the market:


MegaRed Krill Oil:
EPA 50 mg
DHA 24 mg
Total omega-3s (EPA + DHA + other forms) 90 mg
Price: $28.99 for 60 softgels

Source Naturals (a fine company otherwise, by the way):

EPA 150 mg
DHA 90 mg
Total omega-3 fatty acids 300 mg
Price: $24.99 for 60 softgels

Alright, let's do some simple math:

Average volume of blood in the human body (all components): 5000 cc
Percentage of red blood cells (RBCs) by volume: 45%
Total volume RBCs: 2250 cc
Percentage of total volume RBCs occupied by fatty acids:

What tests are MORE important than cholesterol?

12. May 2013 William Davis (8)
In the conventional practice of early heart disease prevention, cholesterol testing takes center stage. Rarely does it go any further, aside from questions about family history and obvious sources of modifiable risk such as smoking and sedentary lifestyle.

So standard practice is to usually look at your LDL cholesterol, the value that is calculated, not measured, then--almost without fail--prescribe a statin drug. While there are indeed useful values in the standard cholesterol panel--HDL cholesterol and triglycerides--they are typically ignored or prompt no specific action.

But a genuine effort at heart disease prevention should go farther than an assessment of calculated LDL cholesterol, as there are many ways that humans develop coronary atherosclerosis. Among the tests to consider in order to craft a truly effect heart disease prevention program are:

--Lipoprotein testing--Rather than using the amount of cholesterol in the various fractions of blood as a crude surrogate for lipoproteins in the bloodstream, why not measure lipoproteins themselves? These techniques have been around for over 20 years, but are simply not part of standard practice.

Lipoprotein testing especially allows you to understand what proportion of LDL particles are the truly unhealthy small LDL particles (that are oxidation- and glycation-prone). It also identifies whether or not you have lipoprotein(a), the heritable factor that confers superior survival capacity in a wild environment ("The Perfect Carnivore"), but makes the holder of this genetic pattern the least tolerant to the modern diet dominated by grains and sugars, devoid of fat and organ meats.

--25-hydroxy vitamin D--The data documenting the health power of vitamin D restoration continue to grow, with benefits on blood sugar and insulin, blood pressure, bone density, protection from winter "blues" (seasonal affective disorder), decrease in falls and fractures, decrease in cancer, decrease in cardiovascular events. I aim to keep 25-hydroxy vitamin D at a level of 60 to 70 ng/ml. This generally requires 4000-8000 units per day in gelcap form, at least for the first 3 or so years, after which there is a decrease in need. Daily supplementation is better than weekly, monthly, or other less-frequent regimens. The D3 (cholecalciferol) form is superior to the non-human D2 (ergocalciferol) form.

--Hemoglobin A1c (HbA1c)--HbA1c represents glycated hemoglobin, i.e., hemoglobin molecules within red blood cells that are irreversibly modified by glucose, or blood sugar. It therefore provides an index of endogenous glycation of all proteins of the body: proteins in the lenses of the eyes that lead to cataracts; proteins in the cartilage of the knees and hips that lead to brittle cartilage and arthritis; proteins in kidney tissue leading to kidney dysfunction.

HbA1c provides an incredibly clear snapshot of health: It reflects the amount of glycation you have been exposed to over the past 90 or so days. We therefore aim for an ideal level: 5.0% or less, the amount of "ambient" glycation that occurs just with living life. We reject the notion that a HbA1c level of 6.0% is acceptable just because you don't "need" diabetes medication, the thinking that drives conventional medical practice.

--RBC Omega-3 Index--The average American consumes very little omega-3 fatty acids, EPA and DHA, such that a typical omega-3 RBC Index, i.e., the proportion of fatty acids in the red blood cell occupied by omega-3 fatty acids, is around 2-3%, a level associated with increased potential for sudden cardiac death (death!). Levels of 6% or greater are associated with reduced potential for sudden cardiac death; 10% or greater are associated with reduced other cardiovascular events.

Evidence therefore suggests that an RBC Omega-3 Index of 10% or greater is desirable, a level generally achieved by obtaining 3000-3600 mg EPA + DHA per day (more or less, depending on the form consumed, an issue for future discussion).

--Thyroid testing (TSH, free T3, free T4)--Even subtle degrees of thyroid dysfunction can double, triple, even quadruple cardiovascular risk. TSH values, for instance, within the previously presumed "normal" range, pose increased risk for cardiovascular death; a TSH level of 4.0 mIU, for instance, is associated with more than double the relative risk of a level of 1.0.

Sad fact: the endocrinology community, not keeping abreast of the concerning issues coming from the toxicological community regarding perchlorates, polyfluorooctanoic acid and other fluorinated hydrocarbons, polybrominated diphenyl ethers (PDBEs), and other thyroid-toxic compounds, tend to ignore these issues, while the public is increasingly exposed to the increased cardiovascular risk of even modest degrees of thyroid dysfunction. Don't commit the same crime of ignorance: Thyroid dysfunction in this age of endocrine disruption can be crucial to cardiovascular and overall health.


All in all, there are a number of common blood tests that are relevant--no, crucial--for achieving heart health. Last on the list: standard cholesterol testing.

Cranberry Sauce

21. November 2012 William Davis (3)
Happy Thanksgiving 2012, everyone, from all the staff at Track Your Plaque!

Here’s a zesty version of traditional cranberry sauce, minus the sugar. The orange, cinnamon, and other spices, along with the crunch of walnuts, make this one of my favorite holiday side dishes.

There are 31.5 grams total “net” carbohydrates in this entire recipe, or 5.25 grams per serving (serves 6). To further reduce carbs, you can leave out the orange juice and, optionally, use more zest.

1 cup water
12 ounces fresh whole cranberries
Sweetener equivalent to 1 cup sugar (I used 6 tablespoons Truvía)
1 tablespoon orange zest + juice of half an orange
½ cup chopped walnuts
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
¼ teaspoon ground cloves

In small to medium saucepan, bring water to boil. Turn heat down and add cranberries. Cover and cook at low-heat for 10 minutes or until all cranberries have popped. Stir in sweetener. Remove from heat.

Stir in orange zest and juice, walnuts, cinnamon, nutmeg, and cloves.

Transfer mixture to bowl, cool, and serve.


Apple Cranberry Crumble

18. November 2012 William Davis (0)
Apple, cranberry, and cinnamon: the perfect combination of tastes and scents for winter holidays!

I took a bit of carbohydrate liberties with this recipe. The entire recipe yields a delicious cheesecake-like crumble with 59 “net” grams carbohydrates (total carbs – fiber); divided among 10 slices, that’s 5.9 grams net carbs per serving, a quantity most tolerate just fine. (To reduce carbohydrates, the molasses in the crumble is optional, reducing total carbohydrate by 11 grams.)

Other good choices for sweeteners include liquid stevia, stevia glycerite, powdered stevia (pure or inulin-based, not maltodextrin-based), Truvía, Swerve, and erythritol. And always taste your batter to test sweetness, since sweeteners vary in sweetness from brand to brand and your individual sensitivity to sweetness depends on how long you’ve been wheat-free. (The longer you’ve been wheat-free, the less sweetness you desire.)


Crust and crumble topping
3 cups almond meal
1 stick (8 tablespoons) butter, softened
1 cup xylitol (or other sweetener equivalent to 1 cup sugar)
1½ teaspoons ground cinnamon
1 tablespoon molasses
1½ teaspoons vanilla extract
Dash sea salt

Filling
16 ounces cream cheese, softened
2 large eggs
½ cup xylitol (or other sweetener equivalent to ½ cup sugar)
1 Granny Smith apple (or other variety)
1 teaspoon ground cinnamon
1 cup fresh cranberries

Preheat oven to 350° F.

In large bowl, combine almond meal, butter, sweetener, cinnamon, molasses, vanilla, and salt and mix.

Grease a 9½-inch tart or pie pan. Using approximately 1 cup of the almond meal mixture, form a thin bottom crust with your hands or spoon.

In another bowl, combine cream cheese, eggs, and sweetener and mix with spoon or mixer at low-speed. Pour into tart or pie pan.

Core apple and slice into very thin sections. Arrange in circles around the edge of the cream cheese mixture, working inwards. Distribute cranberries over top, then sprinkle cinnamon over entire mixture.

Gently layer remaining almond meal crumble evenly over top. Bake for 30 minutes or until topping lightly browned.

Boy, was I wrong!

1. August 2006 William Davis (0)
Around 10 years ago, I was talking to a balloon and stent manufacturer's representative, who was raving about some new device that was due for release to the market. Back then, the sky seemed the limit to cardiac device manufacturers, who were falling over themselves scrambling to design and market the next new device.

The angioplasty market then had ballooned (no pun intended) from nothing to a multi-billion dollar industry. Stents were just getting underway but clearly had potential for being at least as large.

But this was a time when preventive therapies were also beginning to get quite powerful. We had just gotten started doing CT heart scans and were excited about the possibilities, statin drugs were gaining evidence through clinical trials, and the power of many nutritional supplements was finally achieving validation. We were even learning the error of our prior low-fat ways.

So I broadly pronounced to the enthusiastic product representative, "In 10 years, balloons, angioplasty, and stents will occupy this little corner of cardiac care because prevention will have become so powerful. We won't talk about heart procedures. We'll talk about coronary plaque regression!"

I even advised the representative that he should consider a career change in anticipation of the coming wave of preventive strategies.

Was I ever wrong. Despite the power of heart disease prevention--which is indeed true--cardiac device and procedure technology has boomed, both in popularity as well as in revenue success. Device manufacturing and sales are hugely successful. Implanting devices into people is a hugely profitable enterprise.

Since my ill-timed comments to the salesman, Boston Scientific, a major manufacturer of stents and other cardiac devices, reported revenues of $6.2 billiondollars in 2005, a 12% increase over the prior year. Medtronic reported 2005 revenues of $11.3 billion, growing at 15% per year. Clearly, cardiac procedures are still quite popular--and profitable.

My timing was off, but not for long. The huge crest of change in preventive therapies is upon us. That's the premise behind the Track Your Plaque concept: heart disease prevention can't be found in a hospital, is not supported by cardiac device manufacturers, and is not being advocated by most cardiologists or primary care physicians. Yet the tools are getting better and better every day.

Those of you who succeed in halting or reducing your heart scan score are extremely unlikely to add to Boston Scientific's or Medtronic's revenues. Help me spread the word.

Don't forget how dangerous heart disease can be

29. July 2006 William Davis (0)
Sometimes it's easy to get smug when coronary plaque is a reversible process.

When you see people day in, day out, week in, week out, drop their heart scan scores, reversing what could be a dangerous disease, you can sometimes lose sight of just how dangerous coronary disease can be.

Whether I like it or not, I maintain a reasonably active role in hospitals out of necessity. I do need their services occasionally for people with advanced heart disease when I meet them (when regression is not the initial conversation for safety reasons), or valve disease is diagnosed, or someone shows up with congenital or heart muscle diseases. In other words, although we focus on coronary issues, there's more to heart disease than just coronary disease.

This unfortunate case just served to remind me how powerful coronary disease can be. Elizabeth, an active 67-year old, finally came to the hospital after suffering 6 months of chest pain and increasing breathlessness. She hated hospitals and hadn't seen a doctor in 30 years since she was successfully treated for cancer.

In those 30 years, she'd been quite active with family and a small business. But she also smoked 2 packs of cigarettes most of those years.

After she was admitted to the hospital, it became clear that Elizabeth had experienced one, if not several, heart attacks along the way. The entire front 2/3 of her heart was non-functional. If that wasn't bad enough, two of her heart valves were severely diseased and dysfunctional: Her aortic valve barely opened (aortic valve "stenosis", or stiffness) and the mitral valve leaked severely (mitral valve "insufficiency", or leakiness). All of this was confirmed with conventional testing in the hospital, including a heart catheterization.

Elizabeth ended up in emergency surgery--very unusual, by the way, for valve surgery of the sort she had--but died in the first few hours after her procedure. Her heart had simply been too damaged from her heart attacks, and the extraordinary stress of surgery that included two valves was too much. She died on the ventilator.

Coronary disease is a very serious matter. When I see cases like Elizabeth, it boosts my commitment to tell everyone that heart disease--when identified early enough--is a controllable, preventable, even reversible process. For poor Elizabeth, she was much too far down the path of severe, irreversible disease that control or reversal was simply not an option. She was in imminent danger of dying even upon arrival.

It's exciting yet sometimes frightening to know what you have in your hands: The means to control this monster called coronary disease. Use it wisely. But don't lose sight of what it can do it you permit it to grow, fester, and explode.

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.

To remind us what ideal body weight is: Watch an old movie!

26. July 2006 William Davis (0)
Jack was skeptical. At 273 lbs, 5 ft 11 inches, he felt that he was "just right".

"I feel fine. I don't see why you think I should lose weight," he declared. "In fact, when I lost 25 lbs a couple of years ago, everyone said I was too skinny!"

I showed Jack why: He had an HDL of 35 mg/dl, small LDL (over 90% of all LDL particles), an elevated blood sugar of 123 mg/dl (diabetes is officially 126 mg/dl or greater), high blood pressure, and increased inflammation (C-reactive protein). These were all manifestations that his body weight was too much for it to handle.




So I told Jack that we've all forgotten what ideal weight should look like. Our perception of "normal" has been so utterly and dramatically distorted by the appearance of our friends, family, co-workers, and other people around us that we've all lost a sense of what a desirable weight for health should be.




So I suggested to Jack that, if he wanted to rememember what ideal weight is and what people are supposed to look like, just watch old movies.

Old movies, like the 1942 production of Casablanca, or the 1952 production of Singin' in the Rain, show the body build that was prevalent in those days. Look at Humphrey Bogart or Gene Kelly--men with average builds, weighing 140-160 lbs--that's how humans were meant to look.

A report this morning on the Today Show showed the "after" photos of several people following bariatric (weight reduction) surgery. The "after" pictures, from the perspective of ideal weight and ideal health, remain hugely overweight.

We need to readjust our perceptions of weight. The average woman in the U.S. now weighs 172 lbs(!!!). Don't confuse average with desirable.

Diabetes is a choice you make

24. July 2006 William Davis (0)
Tim had heart disease identified as a young man. He had his first heart attack followed by a quadruple bypass surgery at age 38. Recurrent anginal chest pain and another small heart attack led to several stents over three procedures in the first four years after bypass.

Tim finally came to us, interested in improving his prevention program. You name it, he had it: small LDL, low HDL (28 mg/dl), lipoprotein(a), etc. The problem was that Tim was also clearly pre-diabetic. At 5 ft 10 inches, he weighed 272 lbs--easily 80 or more pounds overweight.

Tim was willing to make the medication and nutritional supplement changes to gain control over his seeminglly relentless disease. He even turned up his exercise program and lost 28 lbs in the beginning. But as time passed and no symptoms recurred, he became lax.

Tim regained all the weight he'd lost and some more. Now Tim was diabetic.

"I don't get it. I eat good foods that shouldn't raise my insulin. I almost never eat sweets."

I stressed to Tim that diabetes and pre-diabetes, while provoked acutely by sugar-equivalent foods (wheat products, breads, breakfast cereals, crackers, etc.), is caused chronically by excess weight. If Tim wants to regain control over his heart disease, he needed to lost the weight.

Unlike, say, leukemia, an unfortunate disease that has little to do with lifestyle choices, diabetes is a choice you make over 90% of the time. In other words, if you become diabetic (adult variety, not children's variety) as an adult, that's because you've chosen to follow that path. You've neglected physical activity, or indulged in too many calories or poor food choices, or simply allowed weight to balloon out of control.

But diabetes is also a path most people can choose not to take. And it is a painfully common choice: Nearly two-thirds of the adults in my office have patterns of pre-diabetes or diabetes when I first meet them.

Let me stress this: For the vast majority of adults, diabetes is a choice, not an inevitability.

I'll call the doctor when I feel bad!

Max just had his heart scan. He sat down with the x-ray technologist at the work console while she pointed out the white areas in his coronary arteries that represented plaque.

"It looks like you're going to have a fairly high score," the technologist commented. "The final report will be available after one of our cardiologists reviews your images."

Max shrugged. "Well, I don't feel anything. I'm always running around with work, with my kids, stuff like that. That's better than any stress test. I guess I'll worry about it if it starts to bother me."


You'd be surprised how common this view remains: If it's not bothering you, then just forget about it. It's easy to do, since you have no symptoms, nothing to impair your physical activities. But what are the potential consequences of ignoring your heart scan? Here's a few:

--Prevention and plaque reversal efforts are most effective the earlier you start. From a heart scan score viewpoint, the lower your starting score, the easier it is to gain control over it. More people will succeed in reducing their score when the starting score is lower.

--The role of prevention of heart disease instantly crystallizes when you know your score. Your LDL cholesterol of 142 mg/dl or HDL of 41 mg/dl no longer seem like just numbers of borderline signficance. Instead, they become useful tools to gain control over plaque. They cast your numbers in a new and clear light.

--Knowing your heart scan score today gives you a basis for comparison in future. Your score of, say 250, today, can be 220 in one year. Without your preventive efforts, it will be 30% higher: 325. That's a big difference!

--Sudden death or heart attack--can occur in up to 35-40% of people with hidden heart disease--without warning.

Don't even bother getting a heart scan if you're going to ignore it. I've said it before and I'll say it again: A heart scan is the most important health test you can get--but only if you do something about it.

Coenzyme Q10 and statin drugs

23. July 2006 William Davis (0)
Although drug manufacturers claim that muscle side effects from statin drugs occurs in only around 2% or people or less, my experience is very different.

I see muscle weakness and achiness develop in the majority of people taking Lipitor, Crestor, Zocor, Vytorin, etc. I'd estimate that nearly 90% of people get these feelings sooner or later.

Thankfully, the majority of the time these feelings are annoyances and do not lead to any impairment. Full-blown muscle destruction is truly rare--I've seen it once in over 10 years and thousands of patients.

The higher the dose of statin drug and the longer you take it, the more likely you're going to have muscle aches.

I experienced a strange phemomenon myself today. I worked outdoors for about 4 hours, pulling weeds, digging in the dirt, spreading topsoil. (I have an area of overgrowth in the front yard.) Admittedly, I worked pretty hard and it was a warm, humid day.

I was sore, as you'd expect at age 49. But, much more than that, I was exhausted--my muscles ached and I had barely enough strength to get up the stairs.

Hoping for some relief, I took an extra dose of coenzyme Q10. I usually take 50-100 mg per day. Today, when I felt this overwhelming muscle fatigue, I took an additional 200 mg. Within 10 minutes, I felt a surge of energy. It was, in fact, a perceptible, quite dramatic feeling.

I am thoroughly convinced, through my own experiences on Lipitor (I have a high LDL particle number despite a healthy lifestyle, among other abnormalities), and the experiences of many other people, that coenzyme Q10 can be an extremely useful tool to minimize the muscle aches and weakness of the statin drugs.

If you do indeed need to take one of these agents, coenzyme Q10 is worth knowing about. Supplementing coenzyme Q10 has, for me, been a real lifesaver. For many people, LDL reduction is a crucial part of their heart scan score control program. In my experience, many of them would not be able to take the drug without eozyme Q10.

Blast your LDL with oat bran and almonds

21. July 2006 William Davis (1)
Nearly all of us can use an extra boost in reducing LDL cholesterol. We have a large number of people, in fact, who have reduced LDL into the Track Your Plaque range of 60 mg/dl or less without the use of statin cholesterol-reducing drugs.




Oat bran is among my favorite ways to reduce LDL. Three tablespoons per day is a really effective method to drop your LDL around 20 points. There's twice the beta glucan (soluble, or "viscous", fiber)in oat bran, as compared to the more popular oatmeal. Add oat bran to anything you can think of: yogurt, cottage cheese, vegetarian chili, oatmeal, top desserts with it, etc. Some people struggle to find oat bran in the grocery store. Most health food stores that sell bulk products will have oat bran, usually less than a $1 per pound. Many grocery stores will also have an oat bran hot cereal along with the Cream of Wheat and oatmeal. That's okay, provided the only ingredient is oat bran--no added sugars, etc.





Another dynamite method to reduce LDL 10-20 points is adding raw almonds to your daily food choices. One or two handfuls per day works great. We find it at Sam's Club for around $12.99 for a 3 lb. bag. The plentiful fibers and monounsaturates in almonds keep you full and satisified, take the edge off your sweet tooth, and even blunt the blood sugar rise caused by other foods.

Both these foods are also great ways to combat the metabolic syndrome. Since both fiber-rich oat bran and almonds slow the release of sugars into the blood, blood insulin level is also reduced. This results in a happy cascade of less small LDL, increased HDL, and a reduction in inflammation.

All these wonderful effects contribute to inching you closer to success: dropping your heart scan score.

Pre-diabetes with normal blood sugar

20. July 2006 William Davis (0)
We pay special attention to pre-diabetes, in all its varied manifestations, in the Track Your Plaque program. This is because these factors are potent instigators of coronary plaque growth.

Early in the Track Your Plaque program we ignored these measures. After all, this is a program for heart disease risk reduction, not for mangement of diabetes. But we saw explosive rates of plaque growth when pre-diabetic factors were not controlled--even when cholesterol and related factors were under excellent control.

It became increasingly clear that factors associated with pre-diabetes needed to be managed, as well. This includes small LDL, increased blood sugar, high blood pressure, increased inflammation (as CRP).

Many people, however, have normal blood sugars (100 mg/dl or less) with a high blood insulin level (>10 microunits/ml). (This blood test is available in most laboratories.) This means that they have early resistance to insulin. The pancreas, the source of insulin, responds to the body's unresponsiveness to insulin by increasing insulin production.

Increased blood insulin with normal blood sugar will drive production of higher triglycerides, a drop in HDL, creation of small LDL, and inflammation--and coronary plaque growth, as evidenced by increasing CT heart scan score.

Blood insulin levels can be very effectively dropped by weight loss; exercise; reduction of processed carbohydrates like breads, pretzels, and breakfast cereals; and increased raw nuts and oat products; and vitamin D replacement to normal levels. Drug manufacturers are desperately trying to make this a mandate for drug treatment (Actos, Avandia), but are encountering resistance, since most people without overt diabetes don't want to take diabetic medication (rightly so!).

You and your doctor should consider insulin as a factor to track, especially if you have small LDL, low HSL, or high triglycerides, or any of the other manifestations listed above.

Sometimes small LDL is the only abnormality

19. July 2006 William Davis (0)
Janet is a 58-year old schoolteacher. At 5 ft 3 inches and 104 lbs, she had barely an ounce of fat on her size-2 body. For years, Janet's primary care physician complimented her on her cholesterol numbers: LDL cholesterol values ranging from 100 to 130 mg/dl; HDL cholesterol of 50-53 mg/dl.

Yet she had coronary disease. Her heart scan score: 195.

Lipoprotein analysis uncovered a single cause: small LDL. 95% of all of Janet's LDL particles were in the small category. What was surprising was that this pattern occurred despite her slender build. Weight is a powerful influence on the small LDL pattern and the majority of people with it are overweight to some degree. But not Janet.

How did she get small LDL if she was already at or below her ideal weight? Genetics. Among the genetic patterns that can account for this pattern is a defect of an enzyme called cholesteryl-ester transfer protein, or CETP. This is the exact step, by the way, that is blocked by torcetrapib, the new agent slated for release sometime in future (The manufacturer, Pfizer, is apparently going to sell this agent only packaged in the same tablet as Lipitor. This has triggered an enormous amount of criticism against the company and they are, as a result discussing marketing torcetrapib separately.)

Also note that Janet had a severe excess of small LDL despite an HDL in the "favorable" range. (See my earlier conversation on this issue, The Myth of Small LDL at http://drprevention.blogspot.com/2006/06/myth-of-small-ldl.html.)

With Janet, weight loss to reduce small LDL was not an option. So we advised her to take fish oil, 4000 mg per day; niacin, 1000 mg per day; vitamin D, 2000 units per day; use abundant oat bran and raw almonds, both of which suppress small LDL. This regimen has--surprisingly--only partially suppressed her small LDL pattern by a repeat lipoprotein analysis we just performed. We're hoping this may do it, i.e., stop progression or reduce her heart scan score.

The lesson: Small LDL is a very potent pattern that can be responsible for heart disease, even if it occurs in isolation. And, contrary to conventional thinking, small LDL can occur as an independent abnormality, even when HDL is at favorable levels.

American Heart Association stamp of approval

2. June 2007 William Davis (8)
The American Heart Association (AHA) has a program called the Heart-Check Mark, an "approval" process that permits a food manufacturer to affix the AHA logo and stamp of approval on various food products.

A company simply makes application to the AHA. The application and product details are reviewed and then approved or turned down.

To date, 106 companies have obtained the AHA stamp of approval on 768 products. What kinds of products are on the approved list? Here's a sample:

--Honey Bunches of Oats

--Kellogg's Frosted Mini-Wheats

--Cocoa Puffs cereal

--Cookie Crisp cereal ("The great taste of chocolate chips in every bite!")


There are 764 others. If you doubt this, just go to the store and take a look at the product containers.

What the heck is going on here? Most of us with any judgment know that these products are pure sugar. They may contain "no more" than 15-40 grams sugar per sugar, but the principal products--corn, wheat, fructose--mean that these products are, in effect, nearly pure sugar. Yet they carry the AHA stamp of approval.

What do products like this cause? It's a long list but the major effects include:

--Obesity

--Diabetes

--Drop in HDL

--Rise in triglycerides

--Small LDL particles

--Heightened inflammation (i.e., C-reactive protein)

--Mental cloudiness


Need I go on? Why are products like these and many others deserving of the AHA heart-check approval? Because they lack high fat and saturated fat (3.0 grams, 1.0 grams respectively, by AHA criteria). In other words, just lacking these ingredients means that, to the AHA, they qualify as "heart healthy."

By that same line of reasoning, many candy bars are "heart healthy", as are many cookies and cupcakes.

What's the reason behind this extraordinary absurdity? Is the AHA stupid?

There may be many reasons, but one very suspicious fact becomes immediately obvious when you realize these endorsements product a substantial revenue source for the AHA, since companies must pay for the right to use the heart-check approval mark. Also, just look at the major contributors (millions of dollars) to the AHA: ConAgra, General Mills, Kraft, etc.) You get the picture.

Does this make the AHA evil? Not necessarily. But it seriously erodes credibility. it also should make you very leery of any advice that comes from such an agency that is reluctant to bite the food manufacturer hands that feed it.

In my view, we simply cannot rely on the AHA for genuine, unbiased heart health advice.

"Your heart scan score means nothing"

1. June 2007 William Davis (7)
Charles was visibly confused.

He'd gotten his CT heart scan after hearing one of the local scan center's ads on the radio. His score 2773, obviously in the 99th percentile for any age.

"Do you think the score means anything? My primary doctor said that it was meaningless because it was all in the deep wall of the artery. He said that it has nothing to do with risk for heart attack. As long as I feel good, he says don't do anything."

What exactly did his doctor mean, in the "deep wall of the artery"?

What the doctor is referring to is the fact that some people with a long history (many years) of diabetes or kidney failure (also for many years) tend to develop calcium deposits in the media, or muscular layer of arteries. The media is the tissue thin layer just below the intima, the most inner layer of arteries that we usually associate with atherosclerotic plaque and the layer that is most prone to calcium accumulation that we score on heart scans.

Aging, generally into your late 70s, 80s, and onwards, also increases the likelihood of medial calcification. Lastly, longstanding deficiency of vitamin D encourages medial calcification.

Is there any way to distinguish intimal vs medial calcification on a heart scan? No, there is not. Having read many thousands of CT heart scans, I can tell you that there is no practical way in 2007 to tell the difference.

Then how did this doctor "know" that Charles' calcium was "deep walled" or medial? Simple: He didn't. This was yet another example of ignorance based on old thinking. Unfortunately, he did Charles a serious disservice by dismissing his heart scan score that predicted a 25% per year risk for heart attack.

Interestingly, whether calcium is intimal as in atherosclerotic plaque, or medial, both are strongly associated with risk for heart attack. In other words, if calcium is confined to the intima, heart disease risk is present. If calcium is limited to the media, risk is still present.

In all practicality, the only difference we make of the intima vs. media argument (that is, when the distinction has been made by some other means like intracoronary ultrasound, the test that is truly necessary to distinguish the two patterns) is that medial calcification may be more powerfully related to vitamin D deficiency. Thus, someone with heavy medial calcification may require closer attention to maintaining a perfect year-round blood level of 25-OH-vitamin D3. But that's the only practical difference.

Vitamin D toxicity?

30. May 2007 William Davis (3)
"My primary care doctor said to stop the vitamin D because it's toxic. So I stopped it and I just take a multivitamin. He said that a multivitamin and two glasses of milk a day was all I needed."

So proclaimed Eleanor to me. This happens around once every week by doctors frightened of the vitamin D.

So I reminded Eleanor that, before starting vitamin D supplementation, her blood level of 25-OH-vitamin D3 had been 17 ng/ml--severe deficiency.

On 4000 units per day (oil-based gelcap), her blood level had been 37 ng/ml--still deficient, below the desirable range of 50-60 ng/ml. That's the dose Eleanor's doctor had declared "toxic."

When exactly does deficiency develop? There's not full agreement on this, but Dr. Michael Holick of Boston University, among the most experienced and insightful authorities on vitamin D, states that toxicity is more likely when blood levels exceed 150 ng/ml (Nutr Clin Pract. 2007 Jun;22(3):297-304).

In other words, Eleanor and her doctor should not be concerned with toxicity, but with the persistent levels of deficiency she is suffering.

Some authorities call the behavior of vitamin D "bi-phasic": Deficiency is toxic, excessive levels are toxic. We're really just trying to achieve a middle ground in vitamin D levels that are above deficiency but below toxicity.

In reality, deficiency is exceptionally common. In fact, it's the rule around here (northern U.S.), with >95% of everybody we check severely deficient in winter, mildly-moderately deficient in summer. Very few people approach normal levels year round without supplementation.

Toxicity, on the other hand, is exceedingly rare. I have seen it once in a woman who was taking a toxic dose of 50,000 units a day on the instructions of her (mis-guided) doctor. Thankfully, no ill-effects developed from this little "experiment."

So, it's not toxicity that is the overwhelmingly common worry, but deficiency, severe and sustained.

Non-profit hospitals

30. May 2007 William Davis (0)
Take a look at your local hospital and you're likely to notice several curious things:

1) It is likely non-profit, meaning it enjoys a non-profit status with the Internal Revenue Service and enjoys the tax benefits of not paying taxes on profits. This provides an advantage to tax-protected hospitals. 70% or more of hospitals in the U.S. are "non-profit."

2) Non-profit or no, many hospitals operate under the guise of a religious affiliation, e.g., St. Mary's Hospital, Trinity Hospital, All Saints', Jewish Hospital, etc.

3) Executives in non-profit hospitals can make capitalistic salaries. One CEO of a Milwaukee hospital took home $3.7 million dollars in salary last year. That's not including the very substantial perks and business interests in the spin-off businesses the hospital owns, including pharmacies, drug and medical device disitributors, even a venture capital division. "Non-profit" does not have to mean that executives within the operation can't benefit handsomely.

That same hospital system spends over $10 million dollars in a year in local marketing for TV ads, print advertising, etc. Ads are slick and professionally produced.

Make no bones about it: These are "non-profit" for tax purposes only . They are for-profit in every other sense of the phrase, including rich rewards for the insiders.

Guess how those fat executive salaries and large marketing budgets are paid for? That's right: the 12-inch incision in your chest; the four stents, defibrillator, and repeated nuclear stress tests; the revolving door of hospitalization after hospitalization that typifies the "heart patient" experience.

See the hospital for what it is: In the 21st century, it is no longer a charitable operation worthy of your volunteer time and donations. It is a business no different than Home Depot, IBM, or--Enron. Yes, they do perform needed services, as well. But the perverse equation that often determines who needs hospitalization and who doesn't, who needs a heart procedure and who doesn't, is not always based on necessity but on financial return. Just ask the CEO.

What's the best lipoprotein test?

29. May 2007 William Davis (5)
This is a frequent question from Track Your Plaque Members and others interested in improving their heart disease prevention program beyond that of simple-minded cholesterol testing.

I obtain lipoprotein testing every day on patients. I can tell you with the confidence of having done thousands of these tests that plain, old-fashioned cholesterol testing is like relying on riding a scooter to work compared to an 8-cylinder modern automobile. The scooter might get you there, but any rain, snow, or long distance to travel and you can just forget it.

All too often, lipoprotein testing uncovers abnormalities that standard cholesterol testing simply fails to uncover.

So, among the various lipoprotein tests available, which is best?


There are three commercial tests available today:

1) Gel electropheresis (GGE)--often known by its "brand" name as the Berkeley lipoprotein profile, after Berkeley HeartLabs. GGE uses a gel with an electric field applied to cause lipoproteins to migrate, based on particle size and charge.

2) Vertical auto-profile (VAP)--a form of centrifugation, or high-speed spinning of blood plasma to separate lipoprotein particles.

3) Nuclear magnetic resonance (NMR)--the idea of putting plasma in an NMR (also known as MRI) device to characterize blood proteins.

All three tests do an excellent job. All are competitively priced. All have validating data--lots of it--to justify their broad use (though health insurers, in their vast wisdom, would still have you believe that the tests are "experimental").

But is one better?

Having done many of all three (though least of VAP), I am partial to Liposcience's NMR. (By the way, I receive no fees from Liposcience to use their test, nor to promote it in any way.)

I believe NMR is superior in a few ways:

1) I believe that the LDL particle number is the best way to truly quantify LDL, better than apoprotein B and "direct" LDL.

2) It provides what I believe to be more accurate small LDL measures.

3) It provides intermediate-density lipoprotein (IDL), a post-prandial, or after-eating, measure not available on the other two.

Perhaps I'm biased because I use the NMR most frequently. But I've used it because I felt it yielded superior, more clinically believable, data.

In truth, all three laboratories do an excellent job and you'd be served fine by obtaining any of the three. But my heart goes to NMR.

Vitamin K2, aspirin, fish oil and blood thinning

27. May 2007 William Davis (12)
An interesting question came up from one of our Track Your Plaque Members on the Forum.

"I am now taking 9 mg of vitamin K1 and 1000 mcg of K2.

Does taking this supplement with this much K1 have a counteracting effect on the thinning/anticlotting properties of aspirin and fish oil that I also take?"


Great question (along with lots of other greater discussions we have on the Forum.)

The answer: Vitamin K should have no effect on the platelet-blocking effects of aspirin or fish oil. The majority of blood clot inhibiting effects of aspirin and fish oil arise from their ability to keep blood platelets from "clumping" (just like the TV commercials for Plavix).

Vitamin K, on the other hand, participates in the liver production of blood clotting factors (like II, VII, IX, and X, among others for you curious ones).

Thus, vitamin K-dependent clotting factors and platelet-blocking are two separate pathways to forming blood clots. Some of us refer to the difference as "red clots" from the vitamin K pathway and "white clots" from the platelet pathway, since they really do have this different physical appearance.

The vitamin K2 conversation, like that about vitamin D, is fascinating for its potential to provide the missing link between the tightly-tied fortunes of bone health and atherosclerosis. Why is someone with a high CT heart scan score far more likely to have osteoporosis? Vitamin D and K2 deficiency may provide the missing link for many people.

"Drug no cure for gluttony"

24. May 2007 William Davis (0)
That's the headline I'd like to see associated with rosiglitazone, brand name Avandia.

The recent negative press, whether deserved or not, surrounding the prescription drug rosiglitazone for pre-diabetes and diabetes highlights the fact that drugs never--never--substitute for what we can achieve with lifestyle changes.

Typically, rosiglitazone reduces blood sugar a few milligrams, reduces C-reactive protein, and very modestly reduces triglycerides and its associated evil lipoprotein friends. It also causes an average weight gain of 8 lb in the first year of use.

What will weight loss achieve, especially if accomplished through dramatic reduction or elimination of processed carbohydrates and wheat products, along with fish oil supplementation, vitamin D normalization, and exercise? Extraordinary benefits, far superior to what is achievable with this drug. In fact, while rosiglitazone is a Band-Aid for this process, the lifestyle changes can represent a cure in many or most instances.

It should come as no surprise that a drug that does nothing more than increase sensitivity to insulin cannot erase the devastating effects of an unhealthy life. Take rosiglitazone but neglect exercise, don't bother with vitamin D, indulge in pretzels and breakfast cereals, gain more weight . . . It serves the drug company's agenda better than it serves health.

Rosiglitazone not so rosy?

23. May 2007 William Davis (3)
Dr. Steve Nissen of the Cleveland Clinic published a study that suggests that the pre-diabetes and diabetes drug, rosiglitazone, may increase likelihood of heart attack by 43%.

I say "suggests" because the analysis was something called a "meta-analysis", a re-examination of data obtained by pooling unrelated studies and reanalyzing the data. Strengths of this sort of analysis: Sometimes trends that are not evident in smaller studies finally become evident in the larger numbers of participants obtained through pooling of data. Downside: Any statistician will tell you that a meta-analysis can only suggest an association, it cannot prove it.

Nonetheless, we are talking about people's lives. As they say, if you are taking this drug, also known by the brand name, Avandia, then talk to your doctor. I think that this is sound advice, as there are a number of factors to weigh in decision making. For instance, how far along the diabetic path are you? Have you had negative experiences with other agents?

It will, unfortunately, be months to years before confirmatory evidence on this question become available. In the meantime, Nissen will accuse the drug industry of pushing drugs through the FDA approval process without full safety data. GlaxoSmithKline, the manufacturer of Avandia, will counter with claims of weak data, the existing trials not confirming Nissen's findings, etc. We've seen it before.

My take on this is to step back and look at the broad picture. Do we need yet another reason to say that it's far better to maintain normal body weight, dramatically reduce reliance on processed carbohydrates and wheat, exercise, and following other insulin-sensitizing strategies, rather than rely on insulin-sensitizing drugs? (That's what rosiglitazone is supposed to do.) Metabolic syndrome, also known as pre-diabetes, or diabetes is present to various degrees in two thirds of all adults I meet. Nearly all of it is self-inflicted. Nearly all of it is curable with the above lifestyle strategies if undertaken early enough in the process.

A 190 lb, 5 foot 2 inch woman, or a 220 lb, 5 foot 10 inch man, both of whom are surprised that they have pre-diabetes really need to get a grip on reality and health. To me, it's no surprise that drugs do not reverse all the nasty manifestations of lifestyle gone berserk. It should also come as no surprise that the complex, chaotic physiologic mess created by metabolic syndrome and pre-diabetes is not perfectly managed by adding one drug.

The lipid distorting effects of weight loss

22. May 2007 William Davis (0)
Roger experienced a near-fatal heart attack 6 years ago. He survived thanks to the quick action of bystanders who initiated CPR and called 911. An emergency catheterization was performed and a stent implanted into the closed right coronary artery. But that's not why I tell Roger's story.

Since then, Roger has become comfortable with the idea that he has heart disease. His initial commitment to good nutrition and exercise has waned, as it often does in us distractable humans. So Roger gained about 30 lbs through a long winter, inactivity, eating frozen dinners, and the cookies and baked goodies his daughters made him.

As a result of the weight gain and inactivity, Roger's HDL dropped to 32 mg/dl, triglycerides rose to 211 mg/dl, blood sugar crept up into the pre-diabetic range of 116 mg/dl. Undoubtedly, small LDL was out of control beneath the surface. His tummy reflected the weight gain, flaccid and overhanging his belt.

I read Roger the riot act. I reminded him of what he had experienced and nearly didn't survive. Weight loss and a re-invigoration of his nutrition and exercise efforts was going to be crucial.

Roger listened and took it to heart. Over three months, he lost 24 lbs, a phenomenal result. However, his repeat lipid panel showed an HDL of 28 mg/dl, triglycerides 234 mg/dl, blood sugar unchanged.

"I don't get it! I lose all this weight and the number get worse?!" Roger was understandably upset after his enormous effort.

I told Roger that after a profound weight loss, lipids can go berserk for up to two months after weight has stabilized. Typically, HDL drops and triglycerides rise--the opposite of what we want. But wait another two or so months after weight has stabilized and the numbers begin to look beautiful.

Why does this crazy effect happen? I really don't know and I've never heard a satisfactory explanation for it. But it is very real and quite predictable.

The lesson: after a substantial weight loss, be patient. Check your lipid numbers too soon and you might be confused or disappointed. If you do check them, bear in mind that additional time may need to pass before you see the weight loss fully reflected.

Cholesterol reduction and wheat

22. May 2007 William Davis (0)
In my previous post, Identical twins and the explosive influence of weight , we witnessed an excellent example of the profound influence of food choices and weight control on lipoproteins. The heavier twin among these 35-year old male twins (Steve) had an LDL particle number over two-fold higher than his more slender counterpart (Alfred).

The heavier twin, Steve, got here through numerous and longstanding dietary excesses: fast foods, saturated fats, sweets, processed foods. The conventional answer to Steve's lipid dilemma would be to modestly reduce his reliance on saturated fat, exercise, and limit snacks.

How far would that get Steve? Not very far at all. With regards to his high LDL particle number of 2256 nmol/l (representing an "effective" LDL cholesterol of around 225 mg/dl), it would be reduced a little, perhaps 10%.

Notice, however, that 72% of all Steve's LDL particles are small (1639/2256). This is the pattern that responds dramatically to a sharp reduction in processed carbohydrates, especially wheat-containing products.

If Steve were to eliminate all wheat products--all breads, breakfast cereals, pretzels, cookies, cakes, pasta, crackers--LDL particle number will drop dramatically, perhaps 50%, often more depending on the magnitude of weight loss. Small LDL will respond most obviously and will be sharply reduced, perhaps disappear. Incidentally, these changes might not be well reflected by the conventional calculated LDL cholesterol, since small LDL particles are well-concealed by standard measures.

Reducing corn products, white and brown rice, and potatoes would also add to the effect. But, in 2007, wheat products represent 90% of the problem for the majority of people. Reducing or eliminating wheat therefore yields the biggest effect by a long shot.

Steve therefore represents an excellent example of how reducing processed carbohydrates, esp. wheat-containing products, can yield an unexpected and paradoxical reduction in LDL cholesterol as evidenced by the highly accurate LDL particle number (or apoprotein B). Reducing saturated fat sources also helps, but it certainly will not yield the kind of results most people need. You've got to be smarter than the simple-minded conventional advice.
