Do "Heart Healthy" sterols cause heart disease?

The sterol question continues to pop up.

Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia?

Below, I've reprinted a previous Heart Scan Blog post on sterols.


Sterols should be outlawed

While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.


Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.




Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.




The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












HeartWise orange juice contains 1000 mg sterols per 8 oz serving.













Promise SuperShots contains 400 mg sterols per container.














Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.














MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.














Kardea olive oil has 500 mg sterols per 14 gram serving.










WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.

    Dr. Davis:

    The prostate supplement I give my husband has what is called Phytosterol Complex consisting of 400 mg free sterols and 180 mg of beta-sitosterol.

    I was under the impression for years that beta-sitosterol was good for the prostate.  

    Are these prostate supplements dangerous?

  • Dr. William Davis

    Hi, Steve--

    Benecol is okay, since it has stanol esters which do not enter the blood.

    Take Control is a sterol ester product.

    Kathy--

    Yes, these would fall under sterols.

    What I find baffling about sterols, and some cholesterol drugs too, is the fact the FDA approves them (or their labeling) on the basis they supposedly reduce heart disease, without... well, ever checking if they do in fact reduce heart disease. Zetia would be one example in the drug world.

    Wouldn't it be much nicer if they tested plaque reduction (calcium scoring or even carotid artery ultrasounds), instead of relying on a number that may not matter (cholesterol)?

    This would seem to be yet another case of franken-foods gone wrong.

    Ross's rule of thumb: if a product's packaging argues that it's an especially healthy food, it's probably not food at all.

    Celiac Disease Associated with Dilated Cardiomyopathy.

    South Med J. 2009 Sep 4;
    Authors: Lodha A, Haran M, Hollander G, Frankel R, Shani J

    Celiac disease is an intestinal disorder caused by an immunologic response to gluten, which results in diffuse damage to the proximal small intestinal mucosa with malabsorption of nutrients. An association between celiac disease and nonischemic dilated cardiomyopathy has been noted. Cardiomyopathy has been shown to improve in some patients on a gluten-free diet. We report a case of progressively worsening dilated cardiomyopathy in a patient with documented celiac disease.

    According to the American Heart Association, heart disease is the nation's single leading cause of death for both men and women. At least 58.8 million people in this country suffer from some form of heart disease.
    And on the whole, cardiovascular diseases (the combination of heart disease and stroke) kill some 950,000 Americans every year.
    Still, there are many misconceptions about heart disease: "The biggest misconception is that heart disease only happens to the elderly," said Elizabeth Schilling, CRNP with the Center for Preventive Cardiology Program at the University of Maryland Medical Center.
    In fact, according to the American Heart Association, almost 150,00 Americans killed by cardiovascular disease each year are under the age of 65. And one out of every 20 people below the age of 40 has heart disease.
    So, it is now a wise decision to keep a constant monitoring of your health. Why to take a chance if we have the option. I was in the similar misconception that heart disease are far away waiting for me to get aged. But to my surprise, I was found to be having a calcium deposit in my coronary arteries. I need to have my advance diagnostic scans due reassure whether something really deadly is waiting for me. Though it was some dreadful going on in my life, but I never felt any kind of discomfort in Elitehealth.com advanced diagnostic facility. They were having some of the latest diagnostic equipments and non invasive techniques which made me feel safe.

    I believe Elitehealth.com performs CAT scans for the heart, as posted on their website. I also believe Dr. Davis wrote that these are very high radiation tests, equal approximately to 100 Xrays, compared to the EBT tests that equal roughly 4 Xrays. Your choice....

    Does one need to worry about the sterols in nuts and oils? What levels are we talking about that should be avoided?

    Thanks

    Interesting comment about nuts. They are usually considered heart-healthy, but are they really?

    They are high in Omega 6s and sterols. Just because they can influence cholesterol in a positive way, doesn't mean they are good for you. I've wondered about that too.

  • Kismet

    9/16/2009 11:25:12 PM |

    Anonymous, yeah IIRC they are. Some observational trials clearly suggested that nuts in moderation decrease CVD risk.

    again IIRC.

  • trinkwasser

    10/2/2009 3:45:57 PM |

    I suspect another U curve, or J curve: possibly the small quantities of natural sterols in nuts are beneficial, which has led to their use in overdose quantities, which isn't (unless you're a shareholder in a foodlike substance manufacturing company - if they're cheap enough to manufacture that you can displace more expensive ingredients from your product, then mark up the price with a "heart healthy" tag you're on to a winner)

    Dr. Davis:

    Vitamin D is a steroid and chemically related to phytosterols. As a result it's my feeling that prolonged supplementation with vitamin D will cause atherosclerosis and promote coronary plaques like phytosterols.

    It's an established medical fact that high dose of vitamin D causes atherosclerosis but a small intake of it for many months may have the same effect since vitamin D like phytosterols and corticosteroids bioaccumulates in the body.

    After personally taking sarsaparilla and butcher's broom root (both rich in phytosterols) for a long time I had persistent low-grade fever. After reading that squalene inhibited the action of fat-soluble cancer-causing agents I thought it may bind phytosterols too. I tested it and after 2 weeks my fever disappeared. Upon discontinuation of squalene a few weeks later fever did not return.

    absolutely wrong i think if this were the case can u beleive Dr. william Davis , that almost all Countries including the stringent Canada is allowing Foods Fortified with plant sterols to be sold in retail chains , being a Doc . u shud be careful of scaring the people and hence depleting them of a cure for a Potential Fatal Heart Condition , here are some Conclusion of a study preformed recently :  Several experimental studies in normal and apolipoprotein-E-deficient mice in the study by Weingärtner et al. (6) indicated that the increase in serum plant sterol contents with diet-enriched plant sterol ester consumption worsens arterial function. Humans consuming a diet enriched with plant sterol esters had increased contents of plant sterols in serum and in atherosclerotic aortic valves. However, it remains open whether high plant sterol levels in aortic valves cause atherosclerosis. Even though excessively increased serum plant sterols in serum of sitosterolemic patients with mutated plant sterol metabolism can result in early atheromatosis, no consistent association is available with serum plant sterols and atheromatosis under normal conditions.

You've come a long way, baby

In 1945, the room-sized ENIAC vacuum tube computer was first turned on, women began to smoke openly in public, and a US postal stamp cost three cents. And this was the US government's advice on healthy eating:



 

 

 

 

 

 

 

 

 

 

 

 

 

Green and yellow vegetables; oranges, tomatoes, grapefruit; potatoes and other vegetables and fruits; followed by milk and milk products; meat, poultry, fish, or eggs; bread, flour, and cereals, butter and fortified margarine.

In 2011, the computing power of the ENIAC can be performed by a microchip a few millimeters in width, smoking is now banned in public places, and a first class postage stamp has increased in price by 1466%. And this is the new USDA Food Plate for Americans:



 

 

 

 

 

Have we made any progress over the past 65 years? We certainly have in computing power and awareness of the adverse effects of smoking. But have US government agencies like the USDA kept up with nutritional advice? Compare the 2011 Food Plate with the dietary advice of 1945.

It looks to me like the USDA has not only failed to keep up with the evolution of nutritional thought, but has regressed to something close to advising Americans to go out and buy stocks on the eve of the 1929 depression. Most of us discuss issues like the genetic distortions introduced into wheat, corn, and soy; the dangers of fructose; exogenous glycoxidation and lipoxidation products yielded via high-temperature cooking; organic, free-range meats and the dangers of factory farming, etc. None of this, of course, fits the agenda of the USDA.

My advice: The USDA should stay out of the business of offering nutritional advice. They are very bad at it. They also have too many hidden motives to be a reliable source of unbiased information.

 

 

Fasting with green tea

I've been playing around with brief (18-24 hour) fasts with the use of green tea. Of the several variations on fasting, such as juice "fasts,"  I've been most impressed with the green tea experience.

While the weight loss effects of daily green tea consumption are modest, there seems to be a specific satiety effect that has now been demonstrated in multiple studies, such as this and this. In other words, green tea, through an uncertain mechanism, reduces hunger. The effect is not just due to volume, since the effect cannot be reproduced with hot water alone.

I therefore wondered whether green tea might be a useful beverage to consume during a fast, as it might take the "edge" off of hunger. While hunger during a fast in the wheat-free is far less than wheat-consuming humans, there is indeed an occasional twinge of hunger felt.

So I tried it, brewing a fresh 6-8 oz cup evert two hours or so. I brewed a pot in the morning while at home, followed by brewing single cups using my tea infuser at the office. Whenever I began to experience a hunger pang, I brewed another cup and sipped it. I was pleasantly surprised that hunger was considerably reduced. I sailed through my last 18 hours, for instance, effortlessly. The process was actually quite pleasant.

I brew loose Chinese bancha, sencha, and chunmee teas and Japanese gyokuro tea. Gyokuro is my favorite, but also the most expensive. Bancha is more affordable and I've used that most frequently.

If anyone else gives this a try, please report back your experience.

Dreamfields pasta is wheat

An active question on the blogosphere and elsewhere is whether Dreamfields pasta is truly low-carb. Dr. Andreas Eenfeldt of Diet Doctor detailed his high blood glucose experience with it. Jimmy Moore of Livin' La Vida Low Carb had a similar experience, observing virtually no difference when compared to conventional pasta.

The Dreamfields people make the claim that "Dreamfields' patent-pending recipe and manufacturing process protects all but 5 grams of the carbohydrates per serving from being digested and therefore lessens post-meal blood glucose rise as compared to traditional pasta." They call the modified carbohydrates "protected" carbs.



In other words, they are making the claim that they've somehow modified the amylopectin A and amylose molecules in durum wheat flour to inhibit conversion to glucose.

I'd like to add something to the conversation: Dreamfields pasta is wheat. It is a graphic demonstration that, no matter how you cut it, press it, sauce it up, "protect" it, it's all the same thing: wheat. (It reminds me of a bad girlfriend I had in my 20s: She'd put on makeup, a pretty dress, I'd take her out someplace nice . . . She was still an annoying person who whined about everything.)

Wheat is more than a carbohydrate. It is also a collection of over 1000 proteins, including gliadins, glutens, and glutenins. Gliadins, for instance, are degraded to polypeptide exorphins that underlie the addictive potential of wheat, as well as its withdrawal phenomenon on halting consumption. Gliadin-derived exorphins are also the triggers of auditory hallucinations and paranoid delusions in schizophrenia, as well as behavioral outbursts in children with ADHD and autism.

Wheat is a source of lectins that have the curious effect of "unlocking" the proteins of the intestinal lining, the oddly-named "zonulin" proteins, that protect you from ingested foreign molecules. Ingest wheat lectins and all manner of foreign molecules gain entry into your bloodstream. Cholera works by a similar mechanism. (How about a love story: Bread in the time of cholera?)

Glutens, of course, are responsible for triggering celiac disease, the devastating small intestinal disease that now afflicts 3 million Americans, although 2.7 million don't even know it. Glutens are also responsible for neurologic conditions like cerebellar ataxia, peripheral neuropathy, and dementia ("gluten encephalopathy") and the skin condition, dermatitis herpetiformis.

Then there are the conditions for which the active wheat components have not been identified, including acid reflux, irritable bowel syndrome, asthma (excepting "bakers' asthma), rheumatoid arthritis, edema and fluid retention, and a long list of skin conditions from alopecia to gangrene.

My point: Yeah, Dreamfields pastas, from these instructive experiences, acts a lot like conventional durum wheat pasta. But, even if Dreamfields or somebody else perfects the low-carb aspect of it, it's still wheat. Modern wheat is the genetically tarted-up version of Triticum aestivum, the product of genetic shenanigans from the 1960s and 1970s.

Bet you can't fast

People who continue to consume the world's most destructive grain, i.e., wheat, can rarely endure fasting--not eating for an extended period--except by mustering up monumental willpower. That's because wheat is a powerful appetite stimulant through its 2-hour cycle of exaggerated glycemia followed by a glucose low, along with its addictive exorphin effect. Wheat elimination is therefore an important first step towards allowing you to consider fasting.

Why fast? I regard fasting as among the most underappreciated and underutilized strategies for health.

In its purest form, fasting means eating nothing while maintaining hydration with water alone. (Inadequate hydration is the most common reason for failing, often experienced as nausea or lightheadedness.) You can fast for as briefly as 15 hours or as long as several weeks (though I tell people that any more than 5 days and supervision is required, as electrolyte distortions like dangerously low magnesium levels can develop).

Among its many physiological benefits, fasting can:

  • Reduce blood pressure. The blood pressure reducing effect can be so substantial that I usually have people hold some blood pressure medications, especially ACE inhibitors and ARB agents, during the fast since blood pressure will drop to normal even without the drugs. (A fascinating phenomenon all by itself.)

  • Reduce visceral fat, i.e., the fat that releases inflammatory mediators and generates resistance to insulin.

  • Reduce inflammatory measures

  • Reduce liver output of VLDL that cascades into reduced small LDL, improved HDL "architecture," and improved insulin responsiveness. (The opposite of fasting is "grazing," the ridiculous strategy advocated by many dietitians to control weight. Grazing, or eating small meals every two hours, is incredibly destructive for the opposite reason: flagrant provocation of VLDL production.)

  • Accelerate weight loss. One pound per day is typical.


Beyond this, fasting also achieves unique subjective benefits, including reduced appetite upon resumption of eating. You will find that as single boiled egg or a few slices of cucumber, for example, rapidly generate a feeling of fullness and satisfaction. Most people also experience greater appreciation of food--the sensory experience of eating is heightened and your sense of texture, flavors, sweetness, sourness, etc. are magnified.

After decades of the sense-deadening effects of processed foods--over-sugared, over-salted, reheated, dehydrated then just-add-water foods--fasting reawakens your appreciation for simple, real food. On breaking one of my fasts, I had a slice of green pepper. Despite its simplicity, it was a veritable feast of flavors and textures. Just a few more bites and I was full and satisfied.

Once you've fasted, I believe that you will see why it is often practiced as part of religious ritual. It has an almost spiritual effect.

More on fasting to come . . .

Total cholesterol 220

Talking about total cholesterol is like wearing a tie-dyed t-shirt with the peace sign emblazoned on the front: So totally 60s and out of date.

But talk of total cholesterol somehow keeps on coming back. After I spend 45 minutes discussing a patient's lipoprotein patterns, for instance, they'll asking something like, "But what's my total cholesterol?"

To help put this ridiculous notion of total cholesterol to rest, let me paint several pictures of what total cholesterol can tell you. Let's start with a theoretical, but very common, total cholesterol value of 220 mg/dl. Recall that:

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

Note that LDL cholesterol is nearly always a calculated value. (Yes, your doctor has been treating a calculated, what I call "fictitious," value.)

Rearranging the equation:

Total cholesterol = LDL cholesterol + HDL cholesterol + Triglycerides/5

This relationship means that a great many variations are possible, all under total cholesterol = 220 mg/dl. For example:

LDL 95 mg/dl + HDL 105 mg/dl + Triglycerides 100 mg/dl

(a relatively low-risk pattern for heart disease)

LDL 160 mg/dl + HDL 50 mg/dl + Triglycerides 50 mg/dl

(an indeterminate risk pattern, potentially moderate risk)

LDL 120 mg/dl + HDL 30 mg/dl + Triglycerides 350 mg/dl

(a potentially high-risk pattern)

LDL 60 mg/dl + HDL 25 mg/dl + Triglycerides 675 mg/dl

(an indeterminate risk pattern)

 

That's just a sample of the incredible variation of patterns that can all fall under this simple observation, total cholesterol 220 mg/dl.

Total cholesterol is an outdated concept, one ready long ago for the junk heap of outdated ideas. It's time to throw total cholesterol out in the trash along with beliefs like high-fat intake causes diabetes, whole grains are healthy, and the tooth fairy will leave you money when you leave your molars under the pillow.

Scientists are freakin' liars

So says Tom Naughton, referring to the frequent misinterpretations or misrepresentations of data that characterize much medical research. Dr. Andreas Eenfeldt posted Tom Naughton's recent wonderfully engaging and hilarious talk from Jimmy Moore's Low-Carb Cruise on his Diet Doctor blog.

Comedian and blogger Tom Naughton, also the filmmaker of the movie Fat Head, has brought humor and personality into the low-carb movement. I told my wife to watch it and I could hear her laughing from 30 feet away while watching her laptop.

Dr. Eenfeldt is a sensation of sorts himself, making a big low-carb splash in Sweden. While I missed the cruise this year (due to time pressures), it's clear that Eenfeldt and Naughton have contributed substantially to helping people understand the nonsense that passes as dietary advice in the U.S. and the world.

I watched Naughton's talk while eating my three eggs scrambled with ricotta cheese. I almost spit my eggs out at the computer screen I was laughing so hard.

 

Tell me your wheat elimination story and receive a copy of my new book, Wheat Belly

I'm looking for interesting wheat-free experiences.

For the past year, I have been writing my new book, Wheat Belly . After many, many late nights and soccer games missed, it's now finished. The book will be out in fall, 2011, to be published by Rodale, the Prevention Magazine people.

Wheat Belly will provide, in excruciating detail, the discussion of how wheat was transformed from innocent wild grass to incredible genetically-altered Frankengrain and why it has become such a health nuisance.

I am looking for interesting stories of wheat elimination for the online and special editions of the book. If you have an interesting tale of wheat-elimination successes, woes, or drama, I'd like to hear about it. Even better, if you would agree to be interviewed by phone (not for live use, just for comments and detail), the editors at Rodale will help tell your story.

If we use your story, I will have a free copy of the new Wheat Belly sent to you when it becomes available.

Please post your story in the comments here. I will then need to obtain your contact info, which we will do privately.

 

Real men don't eat carbs

Real men don't eat carbs. At least they don't eat them without eventually paying the price.

How do carbohydrates, especially those contained in "healthy whole grains," impair maleness? Several ways:

--Consume carbohydrates, especially the exceptional glucose-increasing amylopectin A from wheat, and visceral fat grows. Visceral fat increases estrogen levels; estrogen, in effect, opposes the masculinizing effects of testosterone. Overweight males typically have low testosterone and high estrogen, a cause for depression, emotionality, weight gain, and low libido.

--Sugar-provoking carbohydrates like wheat cause visceral fat to accumulate which, in turn, triggers prolactin to be released. Increased prolactin in a male causes growth of breasts: "man boobs,""man cans," "moobs," etc. This is why male breast reduction surgery is booming at double-digit growth rates. In cities like LA, you can see billboards advertising male breast reduction surgery.

--Carbohydrates increase visceral fat that sets the stage for postprandial abnormalities, i.e., markedly increased and persistent lipoproteins, like chylomicron remnants and VLDL particles, that impair endothelial function literally within minutes to hours of ingestion. Impaired endothelial function underlies erectile dysfunction. This is why Internet spammers so enthusiastically send you offers for discounted Viagra.

--Carbohydrates increase blood sugar which provokes the process of glycation, glucose modification of proteins, that also contributes to endothelial dysfunction followed by erectile dysfunction.

Real men therefore avoid carbs.
