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.

Firefighters Face Added Risk of Fatal Heart Attack

22. March 2007 William Davis (1)

Firefighters are twice as likely to die from a heart attack in the line of duty than are policemen, and three times more likely than EMTs.

That's among the headlines run today because of a report in the New England Journal of Medicine documenting a dramatically higher risk for heart attack for fire fighters putting out fires. The above headline is from an excellent report run on NPR radio. You can listen to the webcast at http://www.npr.org/templates/story/story.php?storyId=9047656.

The story sparked comments from experts insisting that all fire fighters should have physicals, should be in better physical condition, should be covered by health insurance (the NPR report said that 1 out of 4 fire fighters lack health insurance). Judging from the indisputable risk firefighters encounter, these are all good ideas.

But if you've been following my blog or the Track Your Plaque program, you know that physicals alone are hopeless exercises for identifying hidden heart disease. Among the solutions: identify whether or not heart disease is present in the first place--do a CT heart scan.

In fact, several local fire companies in my area have done just that: insisting that all firefighters undergo a heart scan. When groups of people like firefighters arrange for heart scans, they gain the advantage of doing so en masse, thereby allowing many scan centers to offer a dramatically reduced price to the city, town, or village that is paying for them. I've even seen many firefighters scanned at no cost.

It would also help to have health insurance, be physically fit, and have a stress test (an exception to my view that stress tests are also useless to screen asymptomatic people for heart disease). But a CT heart scan would settle the question quickly, easily, undeniably, and inexpensively.

Prophylactic bypass surgery?

20. March 2007 William Davis (0)

This question comes up around once a week:

My CT heart scan score is ____. Wouldn't I be better off just getting a bypass (or stent, etc.) and getting it over with? If I know that heart attack is in my future, why not just get it over with?

The most recent source of this question was the wife of a patient. Jack had a heart scan score of 92 in 2005. He made very little effort to correct his causes, permitting pre-diabetic patterns to persist, failed to correct vitamin D, etc. and a repeat heart scan score showed a dramatic rise to 264.

Jack's wife asked whether he should just have a bypass.

There are several problems with this line of reasoning:

1) Bypass surgery does not reduce the long term risk for heart attack.

2) The risk of bypass surgery often outweighs the risk of an asymptomatic heart scan score.

3) Bypass surgery is a temporary "fix," a fancy Band Aid for a disease that progresses after the procedure. One bypass typically prompts another, and another...

4) Bypassing arteries that have vigorous blood flow often causes the bypass graft to not "take" and close within the first few days.

Thankfully, nobody in his right mind has proposed that we perform prophylactic bypass operations.

Of course, hospitals and surgeons would jump at the chance to perform procedures in anybody with some threshhold heart scan score. It would double or triple their business overnight. At $70,000 or more per procedure, they would dance in glee. Of course, you and I would pay for their new burst of wealth by a sharp increase in our health insurance premiums. Not only that, the people who underwent the procedure would not benefit.

Lipitor 80 mg

20. March 2007 William Davis (4)

I'm seeing more and more people taking 80 mg of Lipitor per day. For the most part, these are people who come in for another opinion after a stent or heart attack and are prescribed the drug during their hospitalization.

This practice is based on the results of the PROVE IT-TIMI 22 (PRavastatin Or atorVastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction) trial, and the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, both reported in 2005. In the PROVE IT Trial, 4,000 people experiencing heart attacks were treated with Lipitor (atorvastatin), 80 mg, or Pravachol (pravastatin), 40 mg. There was a reduction in events like recurrent heart attack from 13.1% in the Pravachol group to 9.6% in the Lipitor group. In the REVERSAL Trial, the Lipitor group also showed no plaque growth compared to the Pravachol group, which did progress, with disease tracked by intracoronary ultrasound.

I believe that many of my colleagues took the bait. In a half-hearted effort to reduce events and trend towards better coronary plaque control, writing a prescription for 80 mg rather than a lower dose has become increasingly popular.

Some problems: Despite the favorable tolerance to high dose Lipitor in these trials, I don't know anybody who can tolerate 80 mg per day for more than a few months in real life. In my experience, people inevitably end up with intolerable muscle aches.

Also, I believe it is folly to believe that we can regress coronary plaque on a broad scale by just using one drug that addresses only a single cause (i.e., LDL cholesterol). Yes, drug companies would argue that the statin drugs are so wonderful because of their so-called "pleiotropic", or non-lipid, effects like reducing inflammation. I have seen regression of plaque once using Lipitor alone. We struggle to reduce coronary plaque using a multi-faceted approach. It is highly unlikely that Lipitor alone at a 80 mg dose will be sufficient in most people to regress plaque. How about lipoprotein(a)? Or vitamin D deficiency? Lipitor has no effect on these patterns and people do not regress just by taking statin agents.

Orlistat for weight loss

19. March 2007 William Davis (3)

In early February, the FDA approved orlistat, formerly known as prescription Xenical, for over-the-counter sale. Orlistat is a blocker of fat absorption.

The new OTC version will be called "Alli" (pronounced like "ally") and will come at a dose of 60 mg to be taken three times a day with meals. Prescription Xenical came as a 120 mg tablet. However, the company claims that the reduced dose sacrifices only 5% in reduced fat absorption, dropping from 30% with Xenical to 25% with Alli. It will cost in the neighborhood of $1 to $2 per day, or $30-60 per month, far less expensive than the $110-150 for the prescription form.

Does it work? Is it worth the money? Clinical trials document around 5-10 lbs lost over a 3 to 6 month period, 50% greater than using diet and exercise alone.

Our experience is that it works, though inconsistently. Results depend heavily on how reliant you are on fat calories. If you were to follow a low-fat diet while on the drug, you likely will lose little or no weight, since there's little fat absorption to block. However, I have witnessed more substantial weight loss of 10-20 lbs. in people who follow a higher fat intake in their diet, e.g., a traditional American diet. However, these people gain the weight back immediately because they've made no effort to modify food choices.

It is messy. Even though the clinical trials claims modest inconvenient effects like gas and greasy stools, I have found that it is, without fail, a very annoying product that results in crampiness and frequent messy stools in nearly everybody.

The company has created a glitzy website that you can view at www.myalli.com and promises to provide a personalized program and support for registrants when it is up and running by summer 2007.

I think that's a good idea, since the drug itself is no more than a temporary fix unless it's combined with long-term diet changes. However, the website, I believe, oversells the value of the drug with a drug company's usual over-the-top hints and innuendoes without actually coming out with straight pitches of the truth.

Beware of the vitamin D-blocking effect of Orlistat. The period of time you take it may be a time to resort to some modest sun exposure (10-15 minutes; be careful not to burn), rather than than oil-based vitamin D capsules, in order to avoid the inevitable vitamin D plunge in blood level.

I am not a fan of orlistat, having seen it tried many times with minimal success. However, it is another option for those who are really struggling. Personally, I would try fasting or some of the other strategies we've detailed on the www.cureality.com website before I resorted to orlistat.

Low HDL makes Dr. Friedewald a liar

17. March 2007 William Davis (5)

There's a $22 billion industry based on treating LDL cholesterol, a fictitious number.

LDL cholesterol is calculated from the following equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

So when your doctor tells you that your LDL cholesterol is X, 99% of the time it has been calculated. This is based on the empiric calculation developed by Dr. Friedwald in the 1960s. Back then, it was a reasonable solution, just like bacon and eggs was a reasonable breakfast and a '62 Rambler was a reasonable automobile.

One of the problems with Dr. Friedewald's calculation is that the lower HDL cholesterol, the less accurate LDL cholesterol becomes. If it were just a few points, so what? But what if it were commonly 50 to 100 mg/dl inaccurate? In other words, your doctor tells you that your LDL is 120 mg/dl, but the real number is somewhere between 170 and 220 mg/dl. Does this happen?

You bet it does. In my experience, it is an everyday event. In fact, I'm actually surprised when the Friedewald calculated LDL closely approximates true LDL--it's the exception.

Dr. Friedewald would likely have explained that, when applied to a large population of, say, 10,000 people, calculated LDL is a good representation of true LDL. However, just like saying that the average weight for an American woman is 176 lbs (that's true, by the way), does that mean if you weigh 125 lbs that you are "off" by 41 lbs? No, but it shows how you cannot apply the statistical observations made in large populations to a single individual.

The lower HDL goes, the more inaccurate LDL becomes. This would be acceptable if most HDLs still permitted reasonable estimation of LDL--but it does not. LDL begins to become significantly inaccurate with HDL below 60 mg/dl.

How to get around this antiquated formula? In order of most accurate to least accurate:

--LDL particle number (NMR)--the most accurate by far.

--Apoprotein B--available in most laboratories.

--"Direct" LDL

--Non-HDL--i.e., the calculation of total cholesterol minus HDL. But it's still a calculated with built-in flaws.

--LDL by Friedewald calculation.

My personal view: you need to get an NMR if you want to know what your LDL truly is. A month of Lipitor costs around $80-120. A basic NMR costs less than $90. It's a relative bargain.

Menopause unleashes lipoprotein(a)

16. March 2007 William Davis (0)

Faye was clearly frustrated.

At age 52, she was having chest pains every day. A CT heart scan showed a score of zero. A CT coronary angiogram showed no plaque whatsoever.

"Everything went downhill when my menopause started. I gained weight, I started to have chest pains, my blood pressure went up, my cholesterol shot up."

She saw three physicians, none of whom shed much light on the situation. They ran through the predictable sequence of (horse, not human) estrogens, anti-depressants, suggestions for psychological counseling.

But we checked Faye for lipoprotein(a), which she proved to have at a high level of 182 nmol/l. This explained a lot.

A curious and predictable set of phenomenon occur to females with Lp(a) proceeding through the menopause. As estrogen recedes:

--Lp(a) levels rise dramatically.

--Blood pressure goes up, sometimes creating severe hypertension by mid- to late-50s.

--Chest pain can develop, presumably due to "endothelial dysfunction" or "microvascular angina", both representing abnormal coronary artery constriction facilitated by worsening expression of Lp(a).

All too often, these phenomena get dismissed as simply part of the menopausal package, when they are, in fact, important facets of this very important genetic pattern that confers high risk for heart disease.

If any of this rings familiar for you or a loved one, think Lp(a). Though Faye hadn't yet developed any measurable coronary plaque by her CT heart scan score, it was likely on its way, given the surge in Lp(a) expression as menopause unfolded--unless its recognized and appropriate preventive action taken.

Vitamin D must be oil-based

15. March 2007 William Davis (0)

I've talked about this before, but I need to periodically remind everybody:
Vitamin D must be an oil-based capsule, a gel-cap, not a tablet.

Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago.

However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day.

She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.)

In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations.

You may have to look, but if you want to enjoy the extraordinary benefits of vitamin D replacement, it must be an oil-based capsule. Carlson's and Vitamin Shoppe have excellent prepartions. They raise blood levels substantially and consistently, and they're inexpensive. We pay $5.99 for a bottle of 120 capsules.

Vitamin D for $200?

13. March 2007 William Davis (2)

What if vitamin D cost $200 rather than $2?

In other words, what if cholecalciferol, or vitamin D3, was a patent-protectable agent that would sell for an extravagant price, just like a drug?

Vitamin D would be the hot topic. There would be TV ads run during Oprah, slick magazine two-page spreads with experts touting its outsized benefits, insurance companies would battle over how much your copay should be.

The manufacturer would host large fancy symposia to educate physicians on how wonderful vitamin D is for treatment of numerous conditions, complete with dinner, a show, and gifts. They would hire expert speakers to speak, scientists to have articles ghost-written, give out knick knacks with the brand label inscribed--just like Lipitor, Actos, Vytorin, ReoPro, Plavix . . .

After all, what other "drug" substantially increases bone density (up to 20% in adult females), enhances insulin responses 30% (equivalent to the TZD drugs, Actos and Avandia), and slashes colon cancer risk?

But it's not a drug. That is both vitamin D's strength and its weakness. It's a strong point because it's natural, phenomenally helpful across a variety of conditions, and inexpensive. It is also a weakness because, at $2 a month, no one is raking in the $12 billion annually that Pfizer makes for Lipitor that allows it to fund an enormous marketing campaign.

Vitamin D is a "discovery" of huge importance for health, including making reductions of CT heart scan scores far more likely for more people. And it comes without a prescription.

What's up with garlic?

13. March 2007 William Davis (0)

Fanatic Cook has posted an excellent summary on the recent negative attention cast on garlic preparations, at least for LDL cholesterol reduction.

Go to http://fanaticcook.blogspot.com to view.

I think Fanatic Cook is right--despite the lack of LDL reducing effects, it doesn't necessarily mean no benefit whatsoever. Anti-coagulation and anti-inflammatory effects, in particular, are well proven.

I do think, however, that it argues more in favor of sticking to whole cloves, rather than supplements. The benefits are also likely small. I would view garlic as a soft advantage for your plaque control program. You can do fine without it. You might do slightly better with it.

Drop the pretense

12. March 2007 William Davis (1)

Most hospitals maintain the "Saint _____" in their names, despite many having little or nothing to do with the church.

Out of 15 hospitals in my area, 13 are named after saints.

In my view, a more honest name would be something like "ABC Medical Enterprises, Inc." The profit motive, aggressive marketing tactics, and high CEO salaries would make better sense then. The trend to convert practicing physicians from professionals acting on behalf of patient welfare into paid employees would also be clearer.

Imagine Walmart were to change its name to "St. Mary's Emporium" Would it modify your perception of their business? I think it would. It would cause many people to believe that maybe their work was, at least in part, charitable and being done for the public welfare. But Walmart makes such pretense--they are in business for profit, just like all businesses.

It's time for the pretense to be dropped. Hospitals are cut-throat profit-seeking operations, operating under the guise of charitable, tax-free institutions. It's the farthest thing from the truth.
