Saturated Fat and Coronary Heart Disease, Part III: Cognitive Dissonance

"Die wahrheit triumphiert nie, ihre gegner sterben nur aus." -- Max Planck

(Truth never triumphs, its opponents just die out.)

In Part II of this series I wrote that this installment would be about the "best research" those supporting the saturated fat-cholesterol-heart disease link or "causal chain" might use (here's Part I). In the process of doing my homework for that post I came across something I think fits in here because I essentially want you to have some idea of what you'll be up against.

This supplemental entry began when I hit the blog of Dr. A (a reader & commenter here) in the UK: Livable Low Carb. I'll show you a couple of the graphs she posted in a moment, but for now, how about a quote from the British Heart Foundation website on Diet?

It is now universally recognised that a diet which is high in fat, particularly saturated fat, sodium and sugar and which is low in complex carbohydrates, fruit and vegetables increases the risk of chronic diseases – particularly cardiovascular disease (CVD) and cancer. These risks are outlined in the World Health Organization 2003 report Diet, nutrition and the prevention of chronic diseases. The more recent World Health Organization Global strategy on diet, physical activity and health emphasised further the need to improve diets in individuals and populations across the world.

The dietary changes which would help to reduce rates of coronary heart disease (CHD) in the UK population were detailed in the 1994 report of the Government's Committee on the Medical Aspects of Food and Nutrition Policy (COMA). This recommended a reduction in fat intake, particularly saturated fat intake, a reduction in sodium intake and an increase in fruit and vegetable and complex carbohydrate intake. In the 2003 report Salt and Health, the Scientific Advisory Committee on Nutrition (SACN) (which replaced COMA in 2000) repeated COMA’s guidance on salt intake in adults and introduced additional guidance on reducing salt intake in children. In 2005 the Government dietary objectives were reiterated in Choosing a Better Diet: a food and health action plan.

Research from the World Health Organization and others highlight the specific importance of low fruit and vegetable consumption as a cause of CHD. The World Health Report 2002 estimated that around 4% of all disease burden in developed countries was caused by low fruit and vegetable consumption, and that just under 30% of CHD and almost 20% of stroke in developed countries was due to fruit and vegetable consumption levels below 600g/day. The World Health Organization has yet to calculate the precise proportion of the disease burden due to high sodium intake or high saturated fat intake. [emphasis added]

I considered clipping some of that, but it would only serve to dilute what is clearly intended to be a VERY STRONG MESSAGE: reduce fat, especially saturated fat and eat more fruits & vegetables. But why? This is something I'll get into in much more depth in the final entry, but here's just a tidbit. When you really start digging into CVD stats it becomes clear that CVD deaths and CVD incidence are constantly conflated or at best conveniently left ambiguous. If a researcher wants to tell you that reducing saturated fat has been successful, he'll haul out CVD death stats and indeed, there has been a tremendous decrease in death from CVD over the past decades. But they'll rarely tell you in the same breath that the incidence of cardiovascular disease -- i.e., heart attacks and other CVD markers -- is pretty much as high as ever. So, is the reduction of death more likely a function of decreased saturated fat intake or more likely some other factor like improved urgent and emergency care in the face of a heart attack? As usual, a review of Occam's Razor seems appropriate.

So, now, here's a couple of Dr. A's graphs for saturated fat consumption and fruit & vegetable consumption trends since 1975.

Fruit & Vegetable Consumption

Oh, did I mention? This data comes from the very same website as the quote, above, the British Heart Foundation. You know what? I'm fairly confident that I could take any kid of normal mental function, explain the parameters including the distinction between CVD incidence and death, ask him or her about association and cause, and get the obvious conclusion: time to look elsewhere.

But kids are naturally honest about such things. For them, it'll be another 20 years before they are "fortunate" enough to get paid for lying and manipulating, which brings us to the second case study in cognitive dissonance. Let's begin with the names, 'cause I always name names.

These names, of course, are prominently displayed in large bold font right after the title of the study: Lipid levels in patients hospitalized with coronary artery disease: An analysis of 136,905 hospitalizations in Get With The Guidelines (PDF)

Amit Sachdeva, MD, Christopher P. Cannon, MD, Prakash C. Deedwania, MD, Kenneth A. LaBresh, MD, Sidney C. Smith, Jr, MD, David Dai, MS, Adrian Hernandez, MD, and Gregg C. Fonarow, MD.

Far less prominent, requiring a magnifying glass, are the financial disclosures.

  • Christopher P. Cannon, MD; grants: Accumetrics, AstraZeneca, Bristol-Myers Squibb, GlaxoSmithKline, Merck, Sanofi- Aventis, Schering Plough
  • Prakash C. Deedwania, MD; consultant of AstraZeneca and Pfizer
  • David Dai, PhD; employee of Duke Clinical Research Institute
  • Gregg C. Fonarow, MD; research from Pfizer and GlaxoSmithKline; consultant and honorarium from Abbott, AstraZeneca, GlaxoSmithKline, Merck, Pfizer, and Schering Plough; and chair of the Get With the Guidelines Steering Committee

No potential conflicts of interest there, eh? I guess that "disclosure" is the name of the game, now, and not the simple fact of the matter. Here's a novel idea: how about simply publishing and paying attention to studies where financial disclosures are unnecessary? Yea, yea, it's impractical and I also don't want to unfairly paint with too broad a brush. Moreover, I'm no Luddite when it comes to the great contributions over time of doctors, researchers, and yes: drug companies. But isn't this getting out of hand?

This was a captivating study to read for the cognitive dissonance, the subject of this entry. Remarkable to me is that I can detect no data manipulation or even evasion of data and facts (until the conclusion, which is an evasion to take your breath away). That's what's so interesting. It's all there. Everything is there to make the same childlike conclusion as we did up above: time to look elsewhere.

Here, let's take a look.

LDL Distribution
LDL Distribution

Now that's almost as perfect of a Bell Curve Distribution as you're ever going to see -- and I'd guess that if LDL levels actually ran to zero in people that you'd see an absolutely perfect distribution. I remind you: these are the LDL levels of 137,000 people admitted to a hospital with coronary artery disease. Let's imagine a scenario, for example, measuring blood alcohol content in people involved in automobile accidents. Would that be a Bell Curve, or, would you naturally expect that the higher the BAC, the more accidents (an ever increasing curve)? Now there you have a definite causal relationship and the data is going to show it unambiguously.

Now let's look at some quotes from the study (PDF).

  • Half the patients hospitalized with CAD had admission LDL <100 mg/dL, and LDL <70 mg/dL was observed in 17.6% of patients.
  • Less than one quarter of patients had an admission LDL >130 mg/dL.
  • There were 54.6% of patients hospitalized with CAD with admission HDL levels <40 mg/dL.
  • HDL ≥60 was observed in just 7.8% of patients.
  • Ideal levels (LDL <70 mg/dL and HDL ≥60 mg/dL) were observed in only 1.4% of patients hospitalized with CAD.
  • Among the 21.1% of patients receiving lipid-lowering medications before admission, LDL levels were modestly lower (94.3 ± 36.4 mg/dL) and HDL levels were similar to those not previously treated with lipid-lowering medications (39.6 ± 2.6 mg/dL).
  • Although high serum concentrations of LDL are a major risk factor for CHD, patients may present with CAD events despite LDL levels, which are not considered elevated and fall well within guideline-recommended targets. In the present study, almost half of patients hospitalized with CAD have admission LDL <100 mg/dL, and 17.6% of patients had LDL <70 mg/dL. Even when only patients without prior history of CHD, other atherosclerotic vascular disease, or diabetes were studied, 72.1% have admission LDL <130 mg/dL and 41.5% had LDL <100 mg/dL. Thus, a substantial proportion of patients present with their first or recurrent CHD events well within the current guideline-recommended targets for LDL.
  • Many of these patients presenting with CAD had HDL levels, which are associated with excess risk. High-density lipoprotein cholesterol is inversely related to the risk of CAD. Even modest increases are associated with lower risk for nonfatal MI or death from CHD. There were 54.6% of patients hospitalized with CAD with admission HDL <40 mg/dL. In addition, fewer than 10% of patients had HDL ≥60 mg/dL. Ideal levels (defined as LDL <70 mg/dL and HDL ≥60 mg/dL) were present in only 1.4% of patients hospitalized with CAD.

How about let's put this final quote in bold.

The present study demonstrates that among patients hospitalized with CAD, the admission lipid levels are below that of the general population.

And, so, what's the OBVIOUS conclusion from all these data points, observation and reasoning?

In a large cohort of patients hospitalized with CAD, almost half have admission LDL <100 mg/dL, whereas less than a quarter have LDL >130 mg/dL. The LDL levels <70 mg/dL are observed in only 17.6% of patients. Admission HDL levels are <40 mg/dL in 54.6% of patients hospitalized with CAD, whereas <10% of patients have admission HDL levels ≥60 mg/dL. Ideal lipid levels (LDL <70 mg/dL with HDL ≥60 mg/dL) are seen in only 1.4% of patients hospitalized with CAD. There were reductions in admission LDL and HDL levels over time. These findings provide insights into the lipid levels encountered in recent clinical practice for patients hospitalized with CAD. These findings may provide further support for recent guideline revisions with even lower LDL goals. They also may suggest a clinical need for developing effective treatments to raise antiatherogenic HDL. [emphasis added]

Shorter version: lower the cholesterol guidelines even more (and, hey, why not throw in a few billions of dollars more of statin Rx?), because heart attack victims already have average cholesterol levels less than the general population. OBVIOUSLY; more lower, please. And, while we're at it, let's come up with a few billion dollars market for meds to raise HDL.

Hey, maybe they could hire me to consult on that last point, since my HDL runs in the 130s and directly measured LDL in the 60s. Of course, that requires no meds, but only a diet of real foods high in natural, healthful saturated fat, plenty of animal protein, some veggies, fruits & nuts -- and occasional bouts with full fat, raw dairy.

So, no chance for me to cash in, I guess. I'll have to content myself with naming names of those who put their livelihoods above your health and are willing to engage in head-spinning cognitive dissonance to hold their lucrative positions of authority.

Naked Feet

Well I don't know about the GW overtones or global Kumbaya, but otherwise a good message. I go barefoot as often as possible, even out in public -- such as last night to the hotel room and back to the in-laws this morning. Coming up on 24 straight hours of barefoot.

Sous-Vide Supreme Maiden Voyage: Chicken

It might strike you as odd that with all the various beef and other fancy dishes I do -- putting such care into my sauces and such -- that after laying down $400 for a kitchen appliance I would choose chicken breasts as the first dish.

How often do I do chicken of any kind? Not very. And it's not that I don't like chicken -- I do -- it's just that I usually have something better in mind.

Back when I attended the Doctors Eades' presentation in San Francisco, Mike told me to pay particular attention to the chicken. I did, and here's what I wrote about it.

I must say that the chicken was probably the best in terms of improvement over any other cooking method. Mike had warned me about this before we even got started, and he was sure right. It's really difficult to describe, but it's tender, moist, and has a flavor as though it has been infused with a particularly concentrated chicken stock. And while the skin wasn't exactly crispy, it and the nice layer of fat were just delicious. I believe I'd buy a SousVide Supreme solely for the way it does chicken.

Well, now I can definitely say that it wasn't because it was prepared by Chef Blumenthal. You can do this at home with a Sous-Vide Supreme.

Vacuum Packed Chicken
Vacuum Packed Chicken

Very simple. A pinch of sea salt & slice of butter in each bag. I had a bit of difficulty getting the pump to get going sucking out the bag but by the third time had figured out the trick of moistening the rubber seal and things went easier.

Then it's into the water bath.

In the Sous Vide
In the Sous-Vide

One nice thing is how quickly the water heats up. Of course I began with hot tap water which certainly helps, but I think it was only at around 110 or so and it took only a few minutes to get to 146. And, as advertised, the unit keeps the temperature within 1/3 of one degree F. An hour is all it took to get done, though it's fine if you leave it in longer. That's another advantage, you can't overcook.

Conventional cooking is all about overcooking the outside just enough to get the inside done the way you want it, risking having the inside overdone (dry & stringy) or underdone (crunchy chicken). Here, all you need to do is make sure you leave it in for a minimum amount of time and it's perfectly moist, tender & delicious.

What I did here was to brush the skin with the butter and drippings from the bags and fire them under the broiler for a few minutes. Incidentally, there was only a small amount of moisture other than butter; i.e., the moisture was still inside the meat where it should be.

SANY0023
 

The funny thing is, that probably doesn't look particularly different or better than any nicely prepared chicken breast. In terms of moisture, texture and taste, however, it is totally superior to any chicken I've ever had. In fact, I've had chicken -- and turkey -- that looked fine but was so dry that it made me cough.

Yes, of course I did a sauce. I reduced a quart of quality organic chicken stock to about 1 cup, with 1/2 cube of butter, just a pinch or so of tarragon (less is more with that herb), a bay leaf, and about 3 tbsp of heavy cream. But, I served the sauce on the side so the chicken could be sampled all on its own.

There were four of us and everyone raved. Robert was demonstrating the tenderness by cutting his chicken with a spoon. Bea, uncharacteristically, brought up the sous-vide subject a couple of times today and is anxious for more. Julie did a wonderful salad with bacon bits. I'll put that up in a separate post over the weekend

I'll likely be blogging regularly about this cooking method. I want to try pork chops very soon. Scrambled eggs, too, and I'm looking forward to seeing if I can have perfect soft boiled eggs waiting for me in the morning. While I'm looking forward to doing steaks soon, what really excites me about this is doing other kinds of meat & fish -- far less expensive than grassfed beef -- and attaining a level of satisfaction that rivals your BBQ steak.

The four of us agreed last night that this dish rivaled the pleasure of a perfect medium rare steak. So if I start doing a lot more of this and a bit less grassfed beef I'll pay for the cost of it in no time.

Paleo Pussies

Well that was fun. And you know what? Life is just too fuckin' short to be a paleo pussy, a wimp...an intellectual masturbator in all of this.

No prisoners. No refuge. No quarter.

See, we're dealing with murderers, maimers and their accomplices in academia, research, the medical profession, the big food and drug industry, and of course the total fucking clueless morons in the news media, for whom I reserve special wrath because if they were doing their dammed jobs rather than deep throating big advertiser food & drug cock as much as they possibly can, I wouldn't have to be doing this shit essentially for free -- and as well, a lot of other people could be out Groking on and enjoying life instead of worrying whether they're hearts are going to explode because they didn't buy "cholesterol lowering" fucking Cheerios for Christ's sake.

...Yes, yes, I understand there are other bloggers and commenters out there who want to sit and have tea & crumpets and discuss it all nice and kind like. "Let's not be too threatening. We want to persuade them all."

Yea? Well, FUCK 'EM ALL!

That's what I say. You've got your approach, I've got mine. And as far as I'm concerned, yours has failed utterly and completely. Now it's time to name names, drag those names through the mud, ridicule those names, embarrass family members with the same name...all while having solid reasoning and evidence behind you. Reasoning like: given our evolution, it's highly unlikely that a fucking box of Cheerios is better for you than a steak, asshole. So, just go right on ahead, Mr. Research Fuckhead and keep "associating" meat & its natural fat with bad things. Just keep it up; and I'll keep it up.

I'm glad a guy like Dr. James Carlson isn't a pussy. How could he be, with a book title like this: Genocide: How Your Doctor's Dietary Ignorance Will Kill You!!!!. Do you think Dr. Jim is interested in sitting around for a mutual "stroke" with his enemies, the people killing the patients he has to fix?

Then there's Dr. Malcolm Kendrick. While not quite as rough, I can tell he wants to be. Here's some excerpts from the introduction to The Great Cholesterol Con. Notice the word "con." He's calling them criminals, which they are.

It has reached the point where I feel like shouting, 'Listen guys, I know you need to 'publish or perish,' and the more publicity you can achieve the bigger the next research budget. but you're scaring people half to death. No one knows what to do or what to believe any more. And by the way, your study was RUBBISH! Now go away, grow your beard, and do some proper boring research that no one can understand.'

But they won't. For it's so much more fun to appear on a news programme, talking earnestly about your discovery of the latest possible cause of heart attacks - a danger that the public absolutely, positively, must be warned about. Afterwards, you will probably be invited to lucrative speaking engagements at international cardiology conferences. Does a professorship beckon? 'Who, me? I really don't deserve it, but if you must...'

It's a shame. In a rational society, those sorts of people would be driven away, or, you know very well what... When you add in the element of state subsidy and laws that shield them from both liability and competition, you have insult on top of injury.

They're killing you, slapping you in the face, and laughing all the way to the bank. Continuing with Kendrick.

...And boy, is the cholesterol hypothesis wrong. To adapt a quote from Blackadder, 'It is wronger than a very wrong thing.' Yet it has mesmerised scientists, doctors and the general public for years, exuding a siren song that none can resist, dragging us all to our doom on the sharp rocks of illogicality.

And at whose expense and whose profit?

Yet I think we have been sold a pup. A rather large pup - more of a full-grown blue whale, in fact. But how can I convince you, my fellow jurors, of the truth? You have heard so much, read so much, listened to experts promoting the wonders of statins and ever-greater cholesterol lowering. Adverts bombard us every day with some new fabulous yoghurt, probiotic, margarine or milk drink assuring us that these things lower cholesterol, thus protecting your heart.

On the basis of this never-ending information, many of you will be convinced that you should take statins for the rest of your natural lifespan. Firstly, of course, you will be frightened into action by a blood test demonstrating that you - you sinner - have a raised cholesterol level ('Have you been eating hamburgers again? Have you?'). Everywhere you look, everybody is in agreement about the need to lower your cholesterol level. How can almost everybody be wrong?

In fact, almost everybody being wrong has been a quite normal phenomenon throughout human existence. So the fact that there are only a few dissenting voices out there shouldn't bother you unduly. And medical scientists (an oxymoron if ever there was one), have a long and distinguished history of grabbing entirely the wrong end of the stick, closing their eyes tightly shut, holding on grimly and refusing to listen to anybody else. Another leech anybody, or perhaps a radical mastectomy, or a tonsillectomy, or a removal of toxic colon? What about that old chestnut 'no bacteria can live in the human stomach'? And 'strict bed rest following a heart attack' - how many millions did that kill? [emphasis added]

I really don't think the calm, quiet, deliberate, polite approach accomplishes fuckall but perhaps a decent pension someday for an otherwise mundane life. And even if it did, I still wouldn't respect it. I respect maverick & bravado, risk, in-your-face determination. And besides, I smell a rat in these admonitions for calm deliberation. They're just 'fraidy cats that they're wrong, or they're afraid of offending, or they're afraid of one thing or another. There's a theme there: fear. So they're fuckin' sissies and too afraid to admit it. And it's so unnecessary because it's so irrational. We're RIGHT! No, not in every detail or nuance, but we have the principle foundation set in a Stone Age, and we're fuckin' right goddammit! And you know what I'm going to do about that? I'm going to ridicule the white coats who are wrong, and I'm going to do it with delight. And I'm going to keep doing it relentlessly, ruthlessly.

As I recently wrote in a comment, I won’t be satisfied until they start charging admission to take a piss on Keys’ grave.

More Kendrick.

I am not alone in my beliefs. There are many hundreds of doctors and researchers who agree that the cholesterol hypothesis is bunk. Many keep their counsel, others have been stomped into silence, but a few have had the guts to speak out. However, their voices, unlike those of the implacable medical 'statinators' are not supported by multibillion-dollar pharmaceutical budgets.

In a world dominated by PR-controlled spin, critics of the cholesterol hypothesis get very little airtime. If they did, this world would change, and I hope this book starts the process of change. Because, despite my apparent joviality, I am deadly serious in my belief that the misguided war against cholesterol, using statins, represents something very close to a crime against humanity. So close that you may not be able to spot the difference. [emphasis added]

So, yea, just go right on ahead trying to convince them with showers of daisies. You know what? I don't want 'em even if they can be convinced. I want the whole lot of 'em swept away, viciously, disgraced and left to starve on the streets with rotting sores.

Perhaps that'll illustrate for future generations that this is crucially important work calling for the utmost in honesty and integrity, and by utmost, I mean far in excess of normal or average.

11/24/09 Update: Shorter Brett Mattingly: "My pussy hurts!" From his Twitter feed, in reverse order.

@rnikoley But I know I'm wasting my breath. You keep your 'entertainment' and I'll keep informing.

@rnikoley feel the need to use 'fuck' repeatedly to get your point across, you've proven how childish you are.

@rnikoley Nutritionists, 'dieticians', etc, are idiots and murderers, but once you refer to people with similar views as 'pussies' and ...

@rnikoley Really, you abhor the values of other paleo bloggers who don't share your methodology? I don't disagree that conventional doctors

@rnikoley Respect for those less-informed or with differing views than yourself, for starters.

And, ladies & gents, @rnikoley has just lost my readership. Not that he cares, o'course. It's all about respect if you want progress, Rich.

See, here's the deal. Nobody has to read my blog or like it...though I am always reminded of the bit in Howard Stern's movie Private Parts where some radio network guy is talking to another about Stern's controversial show and it goes something like this, though I don't recall the specific details:

"Those who love him listen for an average of an hour a day."

"And those who hate him?"

"Two hours."

Apparently, Mattingly thinks I'm singling out him and others who advocate a more persuasive approach. Actually, I'm not, and this isn't the first time he's called me out. ...I couldn't give a flying fuck who Brett Mattingly is, what he does, how he approaches paleo or how he represents it to others. And I'd have never cared even if I had known who he was.

I would have never gone to his blog or called him out in a comment or forum elsewhere to say, "man, quit being a pussy." Moreover, I never call out or criticize other paleo / low-carb individuals or bloggers specifically by name on this blog. And in fact, I have pointed and do point to a lot of bloggers who don't share my style and will continue to do so.

But I also note that none of them come around here criticizing me or pathetically lying, implying that there's nothing BUT that. This blog has almost 2,500 posts, the vast majority rather calmly making some argument or observation. And many of them are specifically to assist people on the path.

If anyone doesn't like or can't tolerate my style, that is perfectly fine. but if you want to come around here or pollute my twitter feed with lies and implication that I am only a loose cannon, or "childish," or can't make a real argument with real data, then you can simply GO FUCK YOURSELF ALL THE DAY LONG AND INTO THE HOLIDAY, for all I care.

Tri-Tip & Kohlrabi

Just some quick Sunday morning Food Porn.

Tri Tip Kohlrabi
Tri-Tip & Kohlrabi Mash

I did the roast low & slow in the oven at 225, up to an internal temp of 125. Then a couple minutes per side under the broiler with butter rubbed on the outside. The sauce was 1 1/2 quarts of store bought beef stock with a half stick of butter, some sage, onion and celery, reduced to about 1 cup over a couple of hours.

My mom made the kohlrabi mash in the same manner you'd do potatoes. An excellent alternative.

Wanna Metal?

I'm up at the cabin in Arnold, CA, where Bea & I met my parents late yesterday afternoon after the easiest Friday afternoon drive out of the Bay Area I've had in years. Get this: usually it takes nearly 3:30 to get up here with rush traffic and I made it in 2:40.

My dad just posted this to Facebook. Yep, a touch of wettish snow last night, mostly gone now.

cabin
The Cabin

Anyway, I'm eating my mom's chicken pate with celery, drinking whiskey & soda, and Food, Inc. is downloaded to the Apple TV for viewing after dinner -- which will be low & slow tri-tip, a sauce reduction, kohlrabi and salad. Maybe I'll snap some pictures.

But this post is about entertainment; when I began streaming my iTunes to the Bose earlier, first song up just made me want to share. I'm not much of a metal enthusiast, and this song isn't really metal, but the band is.

Here's Metallica, Nothing Else Matters. Oh, and excuse the advert in the video. But, it was the best version.

Laf Laf Laf Laf Laf

Oh, this is just too delicious not to put up here (via Mike Eades' Twitter feed).

Climate sceptics claim leaked emails are evidence of collusion among scientists - Hundreds of emails and documents exchanged between world's leading climate scientists stolen by hackers and leaked online.

Yes, I've always been a "global warming denier," at least in the sense of it being anthropogenic (man made). I've always thought it the height of being Fooled by Randomness.

...That, and now, good evidence that grant whores and other self-serving lying criminal deadbeats willing to sacrifice their fellow man for their personal advancement really do exist.

A couple of choice quotes.

In one email, dated November 1999, one scientist wrote: "I've just completed Mike's Nature [the science journal] trick of adding in the real temps to each series for the last 20 years (ie, from 1981 onwards) and from 1961 for Keith's to hide the decline."

Of course, everyone "declines to comment." Well, Michael "Hockey Stick" Mann does, and he's really concerned about the truth.

Professor Michael Mann, director of Pennsylvania State University's Earth System Science Centre and a regular contributor to the popular climate science blog Real Climate, features in many of the email exchanges. He said: "I'm not going to comment on the content of illegally obtained emails. However, I will say this: both their theft and, I believe, any reproduction of the emails that were obtained on public websites, etc, constitutes serious criminal activity. I'm hoping the perpetrators and their facilitators will be tracked down and prosecuted to the fullest extent the law allows."

What this demonstrates, to me, is not wide conspiracy but a reflection of what happens when whole livelihoods are staked on a particular hypothesis being correct, something we see all the time in the Cholesterol Con.

I'm closing comments on this one. It's an aside and the last thing we need is a huge comment thread arguing AGW. I'm well aware that many in the paleo and evfit community clearly see what's driving bad dietary advice but seemingly don't see the same principles and dynamics at work elsewhere in the various "disasters" and "epidemics" engineered to scare the crap out of the general populace.

Saturated Fat and Coronary Heart Disease, Part II: The Paleo Principle

In Part I of this series I introduced you to Professor Rod Jackson, who has quite a strong view of the dangers of saturated fat from animal sources in the human diet. This series of posts is intended to examine his claims and, yes, ultimately call them into serious question if not discredit.

In this installment it is my intention to establish a foundation from which we can build. I find it particularly odd that so many of the studies I look at appear to have been done in a vacuum, with no reference to guiding principles; like, human evolution. When epidemiological associations suggest that some variable may be at the root of causing some problem, we ought to be highly suspicious of such associations when they contradict what we would infer from our evolutionary past. While that past is certainly not fully known and we'll probably be gaining knowledge about it for many decades, even centuries or millennia to come, what has been established is sufficient to constitute solid, established knowledge about how we evolved and what we ate that drove our evolution forward.

Against All Odds

Before we proceed, let's keep something in mind, which is this: we are talking about a species of hominid -- Homo sapiens -- that is the last and sole survivor of a long line of bi-pedal hominids going back six million years. As early as 50,000 years ago, there were still three species of humans (erectus, neanderthalensis, sapiens), living concurrently on Earth. Yet, we alone survived, and we did so without a shred of our modern medicine and conveniences. It was the logic of natural selection, chance, environmental upheavals such as floods, droughts, fires, ice ages and perhaps even predation that drove us forward -- that from three angles of varying degrees of niche exploitation (and many before that; evolutionary dead ends) to more generalist, one species came out on top in spite of huge odds against it.

Genetic analysis has now established that at one point the entire world population of our species was only 600 individuals. That is to say, the entire human genome comes from no more than 600 individuals, and this was after the great migration out of Africa, so at one point there must have been many thousands of H. sapiens. And yet, against all those odds, here we are, numbering in the billions.

And given all that, saturated fat -- the fat that makes up a large percentage of our own body fat and that of the animals -- the sort of fat your body will manufacture from excess carbohydrate in your body -- is, in the words of Dr. Jackson, "pure, natural poison?" Does that make any sense? Would that not be about the most surprising thing ever if it were even questionably true?

Imagining The Ridiculous

Suppose some zoologist were to claim that the natural, wild diet of some species of animal is killing them off early. Imagine an omnivorous animal like a bear, for instance. What if some researcher claimed that the super high-fat diet of salmon bellies and fatty skin was detrimental to their health?

What would you think about that? If you have any sense, you'd have to think it absurd. Catching those salmon that run upstream annually in the fall is how bears survive & thrive, packing on the mass they need for winter hibernation. They evolved as the prime animal to exploit that food resource.

But let's stop and think about animals in zoos, where they may be fed some combination of natural food and specially designed chow or other concoction. If you Google for "zoo diets," "animal nutrition," or similar terms, you quickly come to the realization that it's highly varied; lots goes into it and, guess what?

Every Species is Different

And just how do they know this? Well, obviously they have some knowledge about what these animals eat in the wild -- what they evolved to eat -- from observing them. It's not hard. Moreover, they observe their animals in captivity for signs that they're not thriving. And when they don't thrive, what's the first thing you think they'd consider? Would the zookeeper wonder if that saturated fat in the rump steak he's feeding the lions is the culprit, or, would he more likely think something essential was missing from the diet or in the captive environment? As we know, predators typically go for the rich, nutritionally dense organs first, then the meat -- probably the fattiest meat.

Is this difficult? Do you read about zoo animal epidemiology? How about long-term intervention studies employing diets of differing lion chow macro-nutrient composition to compare differences in thriving, disease, mortality? Would you expect to find zoos seeking grants and attempting to study the implications of the meat and fat consumption of a bengal tiger's sustenance and to affirm that the tiger's dry chow is heart healthy over his natural diet in his natural environment? No?

Lifespan! Lifespan!

But wait: zoo animals typically live far longer than their wild counterparts. A male lion in the wild only lives to about 10, but can exceed 20 years of age in a zoo. Perhaps wild ones aren't living long enough to die from all that meat & fat? Does that sound familiar? Well, it should, because that's one of the chief counter-arguments I see against an evolutionary or paleo human diet, even where there is agreement on dietary composition. What they're claiming is that paleolithic hunter-gatherers didn't live long enough to encounter those collection of diseases we tend to call "diseases of civilization."

It's a difficult argument to deal with because there is at least some surface logic to it; and, because it's true that H-Gs and animals in the wild live average shorter lives than those in the zoo of civilization or the zoos we erect for non-human animals. But in the end, we understand that when you remove most of the risks of living in the wild -- like newborn mortality, injury accidents, pathogens, predation, and so on -- that you increase greatly the chances of survival to ripe old ages. Zoos -- for both human and non-human animals -- have been very successful in that. They have been successful in increasing average lifespans. This is not the same as increasing absolute lifespans, and there exists plenty of documentation that hunter-gatherers lucky enough to escape all that brutal nature throws at them, when able to obtain adequate nutrition from a natural diet, are able to rival the advanced ages we find in the human and animal zoos.

Meat & Fat in the Diet

When you run the numbers, there's no other way we could have evolved our huge brains and small guts without a significant quantity of meat & fat in the evolutionary diet. Kleiber's Law dictates that virtually all animals possess a metabolic rate that scales to the ¾ power of the animal's mass. What this means is that animals of different species that weigh the same have the same overall metabolic rate.

You have the same metabolic rate as a chimpanzee that weighs the same as you. Moreover, your heart, lungs, liver, kidneys and so on (major energy expensive tissue) will have comparable metabolic rates. But, your brain will have 4-5 times the metabolic rate of the chimp, and his gut will have 4-5 times the metabolic rate as yours. There's the difference. Why?

Conclusions

There are really only two necessary.

  1. We evolved from primates.
  2. Accomplishing (1) required at first the scavenging of animal-derived protein and fat, which in-turn allowed the shrinking of guts and expanding of brains over six million years.

And, so, the battlefield lines have been drawn. Dr. Jackson asserts that saturated fat is a poison and the chief culprit that underlies heart disease, "the single biggest killer in the western world."

I'm saying that a food so critical and essential to our very unlikely evolution -- against all odds and against all other hominids -- is logically most likely to be extremely healthful. And even if it were not particularly healthful in relation to other nutrition -- no more and no less -- it would be quite illogically odd if it were actually bad for us a priori, which is to say on its face, in any context, even a natural diet of real whole foods.

In Part III I want to attempt to look at what Dr. Jackson and people like him might regard as the best evidence and science out there implicating saturated fat in the diet. If anyone can steer me to some studies they believe are thusly touted by the authorities, I would greatly appreciate it.

11/20/09 Addendum: Prior to publishing this post I was able to have a draft copy reviewed by Dr. Monica Hughes and Dr. Stephan Guyenet, both PhD biologists. Monica helped correct a few errors in my descriptions of our ancestors and Stephan signaled a quibble with the shrinking gut hypothesis, described as follows.

It doesn't specifically imply that we ate more animal foods, but simply that we ate more easily digestible, calorie-dense foods. That could also include cooked starchy tubers. In my opinion, increased animal foods, cooking and starchy tubers probably all contributed to the gut shrinkage. The degree to which each contributed is debatable.

Yes, I'd agree with that, though we would have had to be cooking first, as meat, marrow, brain and other fat can be consumed raw while starchy tubers cannot. And, as it turns out there is some controversy just now over when the advent of cooking actually happened. At any rate, even if you use the advent of H. erectus 1.8 million years ago, you'd still have to conclude that we got near that point through raw animal food for several million years, and which was sufficient to get us large enough brains to invent cooking.

A Fine Day In The Echo Chamber

The morning started off just right. Sunrise on the patio, a cup of coffee, then skipped the morning hour long walk because Bea was off in the morning and wanted to do it.

To top it off, a comment from reader Ian.

Richard, your blog is great and the effort you put into photographing your paleo lifestyle including recipes and cooking techniques is invaluable, as are your regular updates containing links to articles with new relevant information for those pursuing or curious about pursuing this lifestyle.

I’ve been reading it pretty frequently, sometimes multiple times per day just to flip through the old posts and drool over your delicious looking creations and soak up your thoughtful advice.

However, when it comes to your advocacy for the paleo diet, you’re doing yourself and others who are interested in it, and are ignorant of it, a great disservice. Arguing from a position of unchallengeable authority, or even just arrogance peppered with accusations and attempts at mockery is not only unpersuasive but totally alienating to anyone who doesn’t already share your point of view.

In other words, you sound like a shithead. Based on the rest of your blog, i think it’s pretty unlikely you actually are one, but at first glance at one of your forum posts, who would know?

Getting as close as possible to the truth on any subject that falls under scientific scrutiny is difficult, it requires dispassionately analyzing the evidence available and trying to come to the best objective conclusion, then sharing your analysis of the evidence and having it sanity-checked by others.

It’s not a rap battle or a comedy central roast. Calling a guy who has spent a decent portion of his life trying to educate people on nutrition and bring them away from processed foods and to whole natural foods a liar (”inconsistent, bordering on dishonest”) because he hasn’t been persuaded to your point of view on meats and fats yet is pretty uncalled for.

People who believe differently from you are not your enemy to be destroyed, but your ally to be persuaded, this is the only way meaningful knowledge can advance. Making an argument to someone requires having a sensitivity to their point of view, ie understanding what it is and how they established it if possible, and then building on it with a combination of persuasive rhetoric and dispassionate presentations of the evidence you feel supports your position.

Quips like “do the math” and “the religion of plant based dieting” do not serve this cause well. It also sets the tone for the participants and readers of your blog, the first comment was someone making a point about the perceived ecological impact of the meat industry to which someone responded just to call them a “lower case troll”. What the hell is a lower case troll? We’re really going to attack peoples conversational internet grammar because they have an environmental concern? That’s where unnecessary vitriol inevitably leads.

But don’t take my word for it, here’s an excellent and highly amusing video of Neil Tyson making a similar argument to Richard Dawkins.

Though my response didn't mention this (I thought about it later), Ian makes one point I have a certain sensitivity to: "It also sets the tone for the participants and readers of your blog." Yep, that's the risk and I must say that I generally don't like commenters slinging shit (either direction). That's my job. Call it inconsistent, or whatever, but the post is designed to -- as I've often said -- hit & run or slash & burn, then let's hammer it out in comments. Anyway, that's my goal: to use the posting to draw in the traffic, then let's have a decent discussion. And, yes, I don't always live up to that ideal myself.

Anyway, the day gets better. I headed off to the gym shortly after the above & had a really great workout. And then I get back from the gym and, low-&-behold, I've got another comment, this time from John.

Ian, you are absolutely correct about Richard. Having read this blog since before Richard started bowing to Art DeVany, I have noted that Richard’s personality at its core is that of a know-all asshole whose primary mission is to win a fight/argument, not necessarily find or promote truth. In other words, whatever Richard believes today is the Truth. The point of the blog is to satisfy Richard’s congenital need to express his rectitude. He is always “immovable”.

Like a blind pig, Richard’ has latched onto the Paleo thing. For the most part, I find his writing entertaining and often informative (I focus primarily on his cooking explorations), but always subject to scrutiny.

His and Jimmy Moore’s ilk consistently react to criticism the same way their targets do: name-calling and instant dismissal, with a dash of unsubstantiated counter-claim. The echo chamber is an easy/comfortable box in which to live. But that is part of the entertainment of the blog. It can be helpful to read things that often annoy me and keep me questioning and investigating, such as Richard’s comically authoritative perspective. It requires more than what Richard’s intellect possesses to argue his perspective dispassionately.

If you prefer more consistently moderate and accurate reading, read Art. Art’s writing reflects a deep and long-running interest in what makes for healthful living. Art also is an actual prototype for long-term health (as opposed to Richard’s born-again evangelism). Art’s ego is satisfied with considered thoughts and a focus on his own health and on sharing his experiences and observations without shrill ridicule.

If you primarily want entertainment, read Richard. But don’t expect any less lyprocrisy or hyperbole from him than from the people he ridicules.

So, there you have it. Right out in the open. Just taking one in the chin for Team Echo-Chamber.

I've always said -- ask my wife -- that I enjoy being loved & hated just about equally. It's far, far better than indifference, so I've got to give a warm thanks out to both Ian and John for helping to make it a great & effective day.

I think I'm right on track. For those who care to wonder why I engage in the style I do, it's really the only way I could. Entertainment? Yep, that's primarily it, for me -- the lifestyle has its own rewards and I don't need to be doing this to get all the rewards such lifestyle offers. Part of that entertainment is the inputs, i.e., the posts, all of the posts. The other part is the results we get to read about and the help other readers are more than willing to give.

It takes what it takes. But I'm sure both Ian and John spend far more time and effort promoting paleo in their own ways than I do, and I'm sure they've convinced a lot more people than I that a paleo path is a good one. Possibly -- I'd have to look -- but perhaps Ian & John are really the ones responsible for this.

Primal Chicken Pot Pie with Cauliflower Crust

The other day I happened to hit Kat's place, and then her blog, where I saw that she did a chicken pot pie, although she used standard pastry. I was thinking how much I always loved pot pies, and wouldn't it be great to make one. Then it dawned on me: cauliflower crust, just like for pizza. Click on the image to enlarge.

So, I used the original crust recipe almost exactly. However, now I have a food processor and so was able to really make the cauliflower into a mush. To the cup of cauliflower, cup of mozzarella cheese and an egg, I added about a tbsp each of almond meal and coconut flour.

As for the filling, I followed Kat's recipe with the following modifications:

  • Skinless boneless thighs instead of breasts
  • About a cup of organic free range chicken broth which I reduced to almost nothing
  • Organic heavy cream instead of whole milk
  • No flour for thickening (because of the cream)

So, as with the pizza crust where you have to cook it first, I greased the pie tins  with butter and then coated the insides with dough and popped 'em in the oven at 350. Oops. Within a few minutes, all the "dough" was sitting at the bottom of the tins. Cranked up the oven to 400 and let them cook a bit more to release moisture. Next time, I'm going to roll up my cauliflower mash in paper towels to get rid of moisture. Also, more almond meal, coconut flour and maybe some butter or lard will help. Another thing I could do is stack another tin on top to keep the dough in place while it sets up.

At any rate, I took them out after a few more minutes, the dough was still pliable, and so I added a few dashes of coconut flour and was able to get the dough to adhere to the sides of the tins using a fork. Then I added the filling and covered with the remaining raw dough, and then into the oven again at 350, probably 10 minutes or so.

Remove, melt butter on top, and fire under the broiler until well browned.

This was very exceedingly delicious. Definitely something I will do again and attempt to improve.
