Heart scan curiosities 1

27. November 2006 William Davis (3)
Heart scans often reveal more than coronary plaque. From time to time, I'll show some curious findings that people have displayed during routine heart scans.

This 65-year old man had a relatively low heart scan score of 73, but showed an impressive quantity of calcification of his pericardium, the usually soft-tissue sack that encases the heart. The calcified pericardium is the white arcs that surround the heart in the center of the image.



Thankfully, because he's without any symptoms of breathlessness, excessive fatigue, or leg swelling, he won't need to have it surgically corrected. When the pericardium becomes rigid and encircles the heart, it can literally squeeze the heart, a condition called "constrictive pericarditis". The surgery is pretty awful.

This man's calcified pericardium likely resulted from one or more viral infections over his lifetime.

Annual physical

26. November 2006 William Davis (0)
A judge who lives in my neighborhood was found dead in his bed this week from a heart attack. He was 49 years old. His teenage kids found him and performed CPR, but he was cold and long-gone by then.

A close friend of the judge told me that he'd passed an annual physical just weeks before.

This sort of tragedy shouldn't happen. It is easily--easily--preventable. Had this man undergone a heart scan, a score of at least 400 if not >1000 would have been uncovered, and appropriate preventive action could have been taken. The conversation could have centered around the strategies to correct the patterns that triggered his plaque and how he could reduce his score.

Of course, hospitals make use of stories like this to fuel fear that brings hordes to their wards for procedures. Would the judge have required a procedure to save his life, had his heart disease been diagnosed at his annual physical? Not necessarily. Hospitals and cardiologists would try to persuade you that procedures have an impact on mortality. This is simply not true. In fact, the mortality benefits of procedures are questionable except in the midst of acute illness (e.g., unstable chest pain symptoms or heart attack).

Don't be falsely reassured by passing a physical. A physical does nothing to screen you for heart disease. An EKG and stress test, if included, is a lame excuse for heart disease screening. Remember that a stress test is a test of coronary blood flow, not for the presence of coronary plaque. The unfortunate judge most likely had a 30% "blockage" that did not block flow, but ruptured and closed an artery off sometime in the night when he died. A stress test even on the day of his death would not have predicted this.

A CT heart scan would have uncovered it easily, unequivocally, safely.

A curious case of regression

25. November 2006 William Davis (0)
Randi came to me at age 43. Before I'd met her, she'd undergone two heart scans about one year apart. The initial score was 57--not terribly high, but very high for a 41-year old, pre-menopausal female. Recall that rarely do women have any heart scan score above zero before age 50. Randi's 2nd scan had yielded a score of 72, a 27% increase.

Randi even had her lipoproteins assessed and she had the dreaded Lp(a). So when I met her, we discussed the possible choices in Lp(a) treatment: niacin and estrogens as primary treatment, along with LDL reduction to rock-bottom numbers, along with adjunctive DHEA, almonds, ground flaxseed, and fish oil. Sandi was okay with the adjunctive treatments and was already slender and active (BMI <25), and did not show Lp(a)'s evil partner, small LDL. But Randi had no interest in estrogens, even bio-identical preparations, because of the usual uncertainties associated with estrogen replacement. She also proved to be one of the people truly intolerant to anything but the most minute dose of niacin, experiencing prolonged flushing and abdominal cramps with any dose >250 mg.

Randi even attempted a trial of the Mathias Rath concoction of high-dose vitamin C, lysine, and proline as treatment for Lp(a), but we saw no effect on Lp(a).

Unfortunately, this left Randi's Lp(a) essentially uncorrected. Another scan one year later: 90, another 25% increase. 18 months after that, another scan: 120, a 30% increase.

Now 47-years old, Randi had resigned herself to not being able to control her plaque. We'd run out of options. At that point, I'd started to have everyone's vitamin D blood level assessed and then replaced with vitamin D. I did this with Randi, too.

A year after her last scan, she underwent another. The score: 92, a 23% reduction--substantial reversal following a course of unrelenting progression.

Randi and I, of course, both rejoiced with this unexpected success. But it raised some interesting questions: How important is Lp(a) when vitamin D is normalized and small LDL is not a part of the picture? How consistent with regression be with this strategy over time? Would normalization of vitamin D have stopped plaque from becoming established in the first place?

I hope these issues will clarify over time. For now, I'm thrilled with Randi's success. She remains on her present, "incomplete", though successful program.

Note: I would not ordinarily advise a young woman to undergo serial heart scanning with this frequency. Randi had unusual access to a scan center through a relationship with the staff. I am nonetheless grateful for the lessons her experience have taught us.

Fortune teller

25. November 2006 William Davis (0)
Whenever your doctor uses your cholesterol values--total, LDL, HDL, triglycerides--to judge your heart disease risk, he/she is trying to act as your fortune teller.

In some states, fortune telling is illegal, a misdemeanor. The New York State lawbooks say:

A person is guilty of fortune telling when, for a fee or compensation which he directly or indirectly solicits or receives, he claims or pretends to tell fortunes, or holds himself out as being able, by claimed or pretended use of occult powers, to answer questions or give advice on personal matters or to exorcise, influence or affect evil spirits or curses; except that this section does not apply to a person who engages in the aforedescribed conduct as part of a show or exhibition solely for the purpose of entertainment or amusement.
(Source : Wikipedia)

Rather than occult powers, your physician claims to use "medical judgement" to tell your fortune. Except for that distinction, it might be construed as a misdemeanor.


Let's take three typical examples:

58-year old Laura has a high LDL of 195 mg/dl. Her HDL is 52 mg/dl, triglycerides 197 mg/dl. Does she have heart disease?

51-year old Jonathan has an LDL of 174 mg/dl, HDL 34 mg/dl, triglycerides 156 mg/dl. Does Jonathan have heart disease?

71-year old Marian has an LDL cholesterol of 135 mg/dl, HDL 84 mg/dl, triglycerides of 67 mg/dl.

None of the three have symptoms. They all feel well. Nobody is taking a statin cholesterol drug or other agent that would modify the numbers. Jonathan is around 30 lbs overweight. Nobody has an impressive family history of heart disease.

Can you tell who has heart disease and who doesn't? If you can, you're smarter than I am, because I certainly can't tell. But your doctor tries to divine your future by looking at these numbers.

Do they know something that we don't know? No. It's a crude odds game, a guessing game. A guessing game that frequently comes up on the losing end.

These are three real people. Laura, despite her high LDL, has no identifiable coronary heart disease. Jonathan has advanced coronary disease. These were his numbers just prior to his stent. Marian has a moderate quantity revealed by a CT heart scan score of 419.

Don't even try predicting your future from your cholesterol numbers--it simply can't be done. Every day, I see patients and physicians beating their heads over this dilemma. Telling your fortune using pretended occult powers is illegal. Telling your fortune using cholesterol numbers should be, too.

If you want to know if you have coronary plaque, that's the role of the CT heart scan. Plain and simple.

Heart scan score drops like a stone

23. November 2006 William Davis (2)
Matt was dumbfounded when he found out about his heart scan score of 317 in the summer of 2005.

Earlier that year he'd unintentionally lost 20 lbs. in the space of two months and was feeling awful. He was diagnosed with diabetes and put on several medications. He told me that the heart scan score was just adding insult to injury.

As you'd expect in someone with diabetes, Matt had a low HDL, increased triglycerides, and small LDL. Blood pressure and inflammation (C-reactive protein) were issues as well.

Matt's primary care physician had put him on a statin cholesterol drug as soon as he heard about Matt's heart scan score, so we kept this going. What Matt's primary care physician didn't know was that his "true" LDL had been much higher than the conventional calculated LDL had suggested, so the statin agent was a reasonable solution. (Matt was also not terribly motivated to make dramatic changes in lifestyle or food choices. The statin drug was a compromise.)

We added fish oil and vitamin D to his regimen. Though recent data have cast doubt on the value of treating homocysteine levels of around 12.5, Matt's much higher value of 28 was treated with vitamins B6, B12, and folic acid, with a resultant homocysteine of 7.6.

17 months into the Track Your Plaque approach, and Matt's repeat heart scan score: 244, a 23% reduction.

How's that for an early Christmas gift?

"You don't have a uterus. You don't need progesterone"

21. November 2006 William Davis (2)
I was talking with a hospital nurse recently who told me about her lack of energy, blue moods, and other assorted complaints. At age 49, she was exasperated. So I suggested that she ask her gynecologist about progesterone cream.

The gynecologist advised her, "You don't have a uterus. You don't need progesterone." He went on to explain that the only reason to take progesterone was to prevent uterine cancer caused by estrogen.

Then what about progesterone's weight loss benefits? It's effects on increased energy, improved mood, deeper sleep? These benefits, of course, have nothing to do with the uterus.

I've witnessed these benefits in women many times, both in the peri-menopausal period (which starts around your late 30's) and menopause.

Why talk about progesterone when our focus is heart disease and reduction of heart scan scores? Because if progesterone in a woman helps her feel better, more upbeat, and accelerates weight loss, she's more likely to succeed in her plaque-control program.

For additional comments on progesterone, read the Track Your Plaque interview with women's hormone expert, Dr. Nisha Jackson, Females, hormones, and weight control:
An interview with Dr. Nisha Jackson found at http://www.cureality.com/library/fl_04-008njacksonhormones.asp. Dr. Jackson also has a book available called "The Hormone Survival Guide to Perimenopause".







Or, read Dr. John Lee's pioneering books, What Your Doctor May Not Tell You About Menopause: The Breakthrough Book on Natural Hormone Balance and What Your Doctor May Not Tell You About Premenopause: Balance Your Hormones and Your Life from Thirty to Fifty . (An edition that combines the two books is available, also.)

Take a niacin "vacation"

20. November 2006 William Davis (2)
I've been seeing a curious niacin phenomenon that has not, to my knowledge, been reported anywhere in the medical literature.

People with lipoprotein(a), or Lp(a), are best treated with niacin, particularly given the relative lack of other effective therapies. I now have seen approximately 10 people with great initial responses to niacin, only to observe Lp(a) levels slowly drift back up to the starting level over a period of 2-3 years.

In other words, if starting Lp(a) is 200 nmol/l (approximately 80 mg/dl), drops to 70 nmol/l on niacin. Then, over 2-3 years of treatment, it drifts back to 200 nmol/l. Very frustrating.

Somehow, your body's Lp(a) manufacturing mechanism circumvents the niacin, sort of like antibiotic resistance (without the bacteria, of course).

My response to this, though untested, is to have people take an occasional "niacin vacation". I don't mean take a trip to the Bahamas while on niacin. I mean take 2 weeks off from niacin every three months or so. My hope is that the occasional vacation from niacin will allow the body to continue to respond and suppress "resistance". When resuming niacin, you may have to escalate the dose gradually to avoid re-provoking the "flush".

The same "resistance" seems to develop to testosterone in males: an initial drop followed by a gradual increase. Curiously, I've not seen this in females with estrogens, which seems to generate a durable Lp(a) suppressing effect. For this reason, an occasional testosterone "vacation" might also be considered.

So far, I've advised several people to try this. The long-term success or failure, however, is uncertain. I know of no other solutions, however.

If you have Lp(a) and are on long-term niacin, you should consider talking about this issue with your physician. Like many aspects of Lp(a), while fascinating in its complexity, much remains uncertain. Stay tuned.

When LDL is more than meets the eye

18. November 2006 William Davis (0)
Jerry wanted to know what to do with his LDL cholesterol of 112 mg/dl. "My doctor said that it's not high but it could be better."

So I asked him what the other numbers on his lipid panel showed. He pulled out the results:

LDL cholesterol 112 mg/dl

HDL 32 mg/dl

Triglycerides 159 mg/dl


I pointed out to Jerry that, given the low HDL and high triglycerides, his calculated LDL of 112 was likely inaccurate. In fact, if measured, LDL was probably more like 140-180 mg/dl. LDL particles were also virtually guaranteed to be small, since low HDL and small LDL usually go hand-in-hand (though small LDL can still occur with a good HDL).

So Jerry's LDL is really much higher than it appears. To prove it, Jerry will require an additional test, preferably one in which LDL is measured, such as LDL particle number (NMR), apoprotein B, or "direct" LDL.

It's really quite simple. Jerry likely has a high number of LDL particles that are too small. This pattern confers a three- to six-fold increased risk for heart disease.

Treatment requires more than just reducing LDL. Small LDL--an important component of this pattern, responds, for instance, to a reduction in processed carbohydrates like wheat products (breads, breakfast cereals, pretzels, etc.), NOT to a low-fat diet. Weight loss to ideal weight, especially loss of abdominal fat, will yield huge improvements in these numbers. Niacin may be a necessary component of Jerry's treatment program, since it increases LDL size and raises HDL.

For more discussion on measures superior to LDL cholesterol, see my upcoming editorial, Let Dr. Friedewald Lie in Peace (an expansion of a previous Heart Scan Blog). It will be posted on the Cardiologist on Call column on the Track Your Plaque website within the next week.)

Oil-based vitamin D

14. November 2006 William Davis (2)

As time passes, I gain greater and greater respect for the power of restoring vitamin D blood levels to normal, i.e. 50-70 ng/ml. Just yesterday, I saw several people with blood levels of <10 ng/ml--severe deficiency.

Vitamin D deficiency this severe poses long-term risk for osteoporosis, arthritis, colon cancer, prostate cancer, inflammatory diseases, diabetes, and heart disease. Vitamin D appears to make coronary plaque reversal--reduction of your heart scan score--easier and faster.

But it is important that you take the right kind of vitamin D. Several of the people I saw yesterday with vitamin D levels of somebody living in total darkness were taking vitamin D, but they were taking tablets. Tablets are the wrong form. Powder-based tablets, in my experience, yield little or no rise in blood levels. Some preparations generate a small rise but the dose required is huge.

If you're going to take vitamin D, take a preparation that yields genuine and substantial rises in blood levels. This requires an oil-based capsule. I commonly see blood levels of 25-OH-vitamin D3 rise from, say, 10 ng/dl to 60 ng/ml when oil-based capsules are taken.

The most common dose I prescribe to patients is 2000 units per day to females, 3000-4000 units per day to males in non-sun exposed months. Ideally, your dose is adjusted to blood levels.

The Vitamin Shoppe preparation pictured here is one I've used successfully and generates bona fide rises in blood levels. And it costs around $5. Just be sure the preparation you buy is oil-based.

For rapid success, try the "fast" track

14. November 2006 William Davis (1)
Have you tried fasting?

Before your eyes glaze over, let me tell you what I mean. I don't mean a water-only fast for two weeks while you drool over all the temptations around you and you feel sorry for yourself.

I also don't mean the juice fasts that some people use that turn into fruit juice fasts of pure sugar.

Here's another way to do it. Usually, 48 hours of doing this will yield several benefits:

--Weight loss of 1 lb. You will likely experience an even greater weight loss of 2-4 lbs, but much of this will be water loss.

--If you're like me and share a heightened sensitivity to sugars and carbohydrates (like wheat), you may find out just how awful you feel when you eat certain foods. Many people tell me they feel absolutely wonderful when they fast--clearer thinking, increased energy, improved mood. Not the constant gnawing urge to eat they expected.

--After your fast is over, you look back and realize just what large portions of food you were eating. You'll be content with smaller quantities--and enjoy it more.


The "fast" I've used successfully includes two foods:

1) Vegetable juices--that you either juice yourself or purchase. V8 or its equivalent works pretty well. Though purchased V8 is not the best, it's better than nothing and does work reasonably well. If you juice your own vegetable juices, watch out for the diarrhea if you're unaccustomed to vegetable juices. Four 8 oz glasses per day works well.

2) Soy milk--for a source of protein and modest quantity of sugar and fat. I like the Light Silk Soymilk (Vanilla) which contains 80 calories, 2 g fat (0.5 g monounsaturated), 7 g sugar, 6 g protein per 8 oz glass. Four 8 oz glasses of soymilk also work well. In my neighborhood, 8th Continent is another good choice.


Sip both of these throughout the day. Of course, drink water in unrestricted amounts.

What can you expect in your coronary plaque control/heart scan score reversal program? When the fast is over, a rise in HDL, reduction in small LDL, reduction in triglycerides, reduction in blood sugar and insulin, and a smaller tummy. This strategy can be useful to kick-start weight loss efforts or as a periodic way to maintain control over weight and lipid/lipoprotein patterns.

Fish oil: The natural triglyceride form is better

2. February 2011 William Davis (43)
If you have a choice, the triglyceride form of fish oil is preferable. The triglyceride form, i.e., 3 omega-3 fatty acids on a glycerol "backbone," is the form found in the body of fish that protects them from cold temperatures (i.e., they remain liquid at low ambient temperatures).

Most fish oils on the market are the ethyl ester form. This means that the omega-3 fatty acids have been removed from the glycerol backbone; the fatty acids are then reacted with ethanol to form the ethyl ester.

If the form is not specified on your fish oil bottle, it is likely ethyl ester, since the triglyceride form is more costly to process and most manufacturers therefore boast about it. Also, prescription Lovaza--nearly 20 times more costly than the most expensive fish oil triglyceride liquid on a milligram for milligram basis--is the ethyl ester form. That's not even factoring in reduced absorption of ethyl esters compared to triglyceride forms. Remember: FDA approval is not necessarily a stamp of superiority. It just means somebody had the money and ambition to pursue FDA approval. Period.

Taking any kind of fish oil, provided it is not overly oxidized (and thereby yields a smelly fish odor), is better than taking none at all. All fish oil will reduce triglycerides, accelerate clearance of postprandial (after-eating) lipoprotein byproducts of a meal (via activation of lipoprotein lipase), enhance endothelial responsiveness, reduce small LDL particles, and provide a physical stabilizing effect on atherosclerotic plaque.

But if you desire enhanced absorption and potentially lower dose to achieve equivalent RBC omega-3 levels, then triglyceride forms are better.

Here are cut-and-pasted abstracts of two of the studies comparing forms of fish oil.

Bioavailability of marine n-3 fatty acid formulations.

Dyerberg J, Madsen P, Moller JM et al. 
Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Copenhagen, Denmark.

Abstract

The use of marine n-3 polyunsaturated fatty acids (n-3 PUFA) as supplements has prompted the development of concentrated formulations to overcome compliance problems. The present study compares three concentrated preparations - ethyl esters, free fatty acids and re-esterified triglycerides - with placebo oil in a double-blinded design, and with fish body oil and cod liver oil in single-blinded arms. Seventy-two volunteers were given approximately 3.3g of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) daily for 2 weeks. Increases in absolute amounts of EPA and DHA in fasting serum triglycerides, cholesterol esters and phospholipids were examined. Bioavailability of EPA+DHA from re-esterified triglycerides was superior (124%) compared with natural fish oil, whereas the bioavailability from ethyl esters was inferior (73%). Free fatty acid bioavailability (91%) did not differ significantly from natural triglycerides. The stereochemistry of fatty acid in acylglycerols did not influence the bioavailability of EPA and DHA.

Enhanced increase of omega-3 index in response to long-term n-3 fatty acid supplementation from triacylglycerides versus ethyl esters.

Neubronner J, Schuchardt JP, Kressel G et al. 
Institute of Food Science and Human Nutrition, Leibniz Universität Hannover, Am Kleinen Felde 30, Hannover, Germany.

Abstract

There is a debate currently about whether different chemical forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are absorbed in an identical way. The objective of this study was to investigate the response of the omega-3 index, the percentage of EPA+DHA in red blood cell membranes, to supplementation with two different omega-3 fatty acid (n-3 FA) formulations in humans. The study was conducted as a double-blinded placebo-controlled trial. A total of 150 volunteers was randomly assigned to one of the three groups: (1) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as reesterified triacylglycerides (rTAG group); (2) corn oil (placebo group) or (3) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as ethyl ester (EE group). Volunteers consumed four gelatine-coated soft capsules daily over a period of six months. The omega-3 index was determined at baseline (t(0)) after three months (t(3)) and at the end of the intervention period (t(6)). The omega-3 index increased significantly in both groups treated with n-3 FAs from baseline to t(3) and t(6) (P < 0.001). The omega-3 index increased to a greater extent in the rTAG group than in the EE group (t(3): 186 versus 161% (P < 0.001); t(6): 197 versus 171% (P < 0.01)). Conclusion: A six-month supplementation of identical doses of EPA+DHA led to a faster and higher increase in the omega-3 index when consumed as triacylglycerides than when consumed as ethyl esters.

Diarrhea, asthma, arthritis--What is your wheat re-exposure syndrome?

30. January 2011 William Davis (52)
Have you experienced a wheat re-exposure syndrome?

As I recently discussed, gastrointestinal distress--cramps, gas, diarrhea--is the most common "syndrome" that results from re-exposure to wheat after a period of elimination.

Others experience asthma, sinus congestion and infections, mental "fogginess" and difficulty concentrating, or joint pains and/or overt swelling.

Still others say there is no such thing.

Let's take a poll and find out what readers say.

Marathoners, triathletes, and heart disease

30. January 2011 William Davis (0)
Curious thing: People with lipoprotein(a) gravitate towards elite levels of exercise.

I tell my lipoprotein(a) patients that, if they want to see a lot of other people with lipoprotein(a), go to a marathon or triathlon.

This effect applies more to males than to females, just as the fascination with numbers seems to be confined to men, too. That's why I've posted in past about the "prototypical" lipoprotein(a) male.

I believe this is a big part, perhaps the only, reason why there seems to be a modest increased risk for cardiovascular events despite high exercise levels in marathoners. It has nothing to do with the exercise itself; it has to do with the kind of people who choose to exercise at this level.

The best fish oil

29. January 2011 William Davis (30)
The best fish oils available are the liquid forms. Contrary to many people's expectations, the best liquid fish oils have no fishy odor or taste.

I use a lot of liquid fish oils because of the higher doses we use in the Track Your Plaque program, as well as our strategy of high-dose fish oil to reduce lipoprotein(a). Women, in particular, don't like taking the oodles of capsules required to achieve the higher doses we need. So the ladies really like the liquid forms.

The best liquid fish oils are non-fishy, highly-concentrated, and come in the better absorbed triglyceride form. Many capsules, including prescription Lovaza, are the less well-absorbed ethyl ester form. Several studies, such as this one, have now demonstrated that the naturally-occurring triglyceride form yields higher blood (RBC) levels of omega-3 fatty acids, likely due to more efficient digestion via pancreatic lipase.

While there are many good forms of fish oil and only a few bad, these are the best of the best:

Pharmax
The Pharmax Finest Pure Fish Oil with Essential Oil of Orange contains 1800 mg EPA + DHA per teaspoon. This is the preparation I've been taking.

Nordic Naturals
The Nordic Naturals lemon-flavored ProOmega Liquid contains 2752 mg EPA + DHA per teaspoon, the most concentrated of any fish oil I've seen.

(This list is not exclusive. These are just two brands I've used extensively with good results.)

These highly-concentrated, triglyceride forms are more expensive, due to their concentrated nature. 1 teaspoon Pharmax fish oil, for example, provides an equivalent quantity of omega-3 fatty acids as 6 standard fish oil capsules on a milligram for milligram basis, but more like 8 to 9 capsules when absorption efficiency is factored in. The triglyceride form is also more laborious to manufacture. On our Track Your Plaque Marketplace, our Pharmax 500 ml runs $58.95 list. (500 ml provides 100 teaspoons or 600-capsule equivalent.)

Note that, minus the protection of the capsule, liquid fish oils will oxidize if not refrigerated. So be sure to keep your liquid fish oil in the fridge.

What do Salmonella, E coli, and bread have in common?

28. January 2011 William Davis (22)
Say you happen to eat some chicken fingers contaminated with bacteria because the 19-year old kid behind the counter failed to wash his hands after using the toilet, or because the kitchen is poorly managed with unwashed counters and cutting boards, or because the food is undercooked. You get a bout of diarrhea and cramps, along with a desire to banish chicken from your life.

Here's yet another odd wheat phenomenon: About 30% of people who eliminate wheat from their lives experience an acute food poisoning-like effect on re-exposure. You've been wheat-free for, say, 6 months. You've lost 25 lbs from your wheat belly, you've regained energy, joints feel better. You go to an office party where they're serving some really yummy looking bruschetta. Surely a couple won't hurt! Within a hour, you're getting that awful rumbling and unease that precede the explosion.

The majority of people who experience a wheat re-exposure syndrome will have diarrhea and cramps that can last from hours to days, similar to food poisoning. (Why? Why would a common food trigger a food poisoning-like effect? It happens too fast to attribute to inflammation.) Others experience asthma attacks, joint pains that last 48 hours to a week, mental fogginess, emotional distress, even rage (in males).

Wheat re-exposure in the susceptible provides a tidy demonstration of the effects of this peculiar product of genetic research. So if you are wheat-free but entertain an occasional indulgence, don't be surprised if you have to make a beeline to the toilet.

The world of intermediate carbohydrates

28. January 2011 William Davis (0)
There are clear-cut bad carbohydrates: wheat, oats, cornstarch, and sucrose. (Fructose, too, but in a class of bad all its own.)

Wheat: The worst. Not only does wheat flour increase blood sugar higher than nearly all other carbohydrates, it invites celiac disease, neurologic impairment, mental and emotional effects, addictive (i.e., exorphin) effects, asthma, irritable bowel syndrome, acid reflux, sleepiness, sleep disruption, arthritis . . . just to name a few.

Oats: Yeah, yeah, I know: "Lowers cholesterol." But nobody told you that oats, including slow-cooked oatmeal, causes blood sugar to skyrocket.

Cornstarch: Like wheat, cornstarch flagrantly increases blood sugar.It also stimulates appetite. That's why food manufacturers put it in everything from soups to frozen dinners.

Sucrose: Not only does sucrose create a desire for more food, it is also 50% fructose, the peculiar sugar that makes us fat, increases small LDL particles, increases triglycerides, slows the metabolism of other foods, encourages diabetes, and causes more glycation than any other sugar.

But there are a large world of "other" natural carbohydrates that don't fall into the really bad category. This includes starchy beans like black, kidney, and pinto; rices such as white, brown, and wild; potatoes, including white, red, sweet, and yams; and fruits. It includes "alternative" grains like quinoa, spelt, triticale, amaranth, and barley.

For lack of a better term, I call these "intermediate" carbohydrates. They are not as bad as wheat, etc., but nor are they good. They will still increase blood glucose, small LDL, triglycerides, etc., just not as much as the worst carbohydrates.

The difference is relative. Say we compare the one-hour blood glucose effects of 1 cup of wheat flour product vs. one cup of quinoa. Typical blood sugar after wheat product: 180 mg/dl. Typical blood sugar after quinoa: 160 mg/dl--better but still pretty bad.

Some people are so carb-sensitive that they should avoid even these so-called intermediate carbohydrates. Others can have small indulgences, e.g., 1/2 cup, and not generate high blood sugars.

Heroin, Oxycontin, and a whole wheat bagel

25. January 2011 William Davis (27)
For a substantial proportion of people who remove wheat from their diet, there is a distinct and unpleasant withdrawal syndrome. Here are the comments of Heart Scan Blog reader, Scott, from Texas:

Hello Dr. Davis,

I've been experimenting with diet, converging upon a Paleo type diet, but I keep running into problems. I have isolated the problem to cutting out wheat.

Sugar, rice, fruit, corn, potatoes, etc. are relatively ok to add or remove from the diet, but cutting out wheat in particular brings on a moderate headache with heavy fatigue all day long. This resembles the wheat withdrawal symptoms I found on your blog. As I write this, I'm on day 8 of wheat-free. I consume a fair variety of meat and veggies each day with a moderate amount of white rice for carbs. Perhaps a bowl of corn flakes with milk and half a bar of dark chocolate a day. I've learned from experience over the past 5 months or so that none of these foods affect the withdrawal. It's purely wheat.

My question is, what is the range of times for withdrawal symptoms that you've heard from different people? Has there been anyone who never recovered from the wheat withdrawal symptoms even after many months?

It's very tough to get work done like this, and even though my body and head feel much healthier in general, my sinuses have cleared, don't have to take a big nap after I eat, etc., I don't want to go down a path where this is the way things are going to be forever. 


People who have never experienced wheat withdrawal pooh-pooh the effect. But, for about 30% of people, wheat withdrawal is a real, palpable, and sometimes incapacitating experience.

Beyond removing an exceptionally digestible carbohydrate that yields blood sugar rises higher than nearly any other known food (due to the unique amylopectin structure of wheat-derived carbohydrate), wheat withdrawal is a form of opiate withdrawal, somewhat like stopping heroin, Oxycontin, and other opiates. Stop eating whole wheat toast for breakfast, whole grain sandwiches for lunch, or whole grain pasta for dinner, and the flow of exorphins, i.e., exogenous morphine-like compounds, stops. You experience dysphoria (sadness, unhappiness), mental "fog," inability to concentrate, fatigue, and decreased capacity to exercise. It is milder than withdrawal from prescription opiates. Unlike withdrawal from more powerful opiates like heroine, there are, thankfully, no seizures or hallucinations. There are also no deaths.

In my experience, most people get through with wheat withdrawal in about 5 days. An occasional person will struggle for as long as 4 weeks. Thankfully for Scott, I've never seen it last longer than 4 weeks. (Interestingly, people who survive the withdrawal syndrome are often prone to a peculiar re-exposure phenomenon that I will discuss in future, i.e., they get sick upon re-exposure.)

The modern dwarf mutant variant of Triticum aestivum (that our USDA urges us to eat more of) contains greater proportions of gluten proteins compared to wheat pre-1970; glutens are the source of wheat-derived exorphins.

Incidentally, a drug company should be releasing a drug in the next year that will contain naltrexone, an oral opiate blocking drug, for a weight loss indication. They claim it is a blocker of the "mesolimbic reward system." I say it's a blocker of wheat exorphins.

The five most powerful heart disease prevention strategies

24. January 2011 William Davis (39)
You've seen such lists before: 5 steps to prevent heart disease or some such thing. These lists usually say things like "cut your saturated fat," eat a "balanced diet" (whatever the heck that means), exercise, and don't smoke.

I would offer a different list. You already know that smoking is a supremely idiotic habit, so I won't repeat that. Here are the 5 most important strategies I know of that help you prevent heart disease and heart attack:

1) Eliminate wheat from the diet--Provided you don't do something stupid, like allow M&M's, Coca Cola, and corn chips to dominate your diet, elimination of wheat is an enormously effective means to reduce small LDL particles, reduce triglycerides, increase HDL, reduce inflammatory measures like c-reactive protein, lose weight (inflammation-driving visceral fat), reduce blood sugar, and reduce blood pressure. I know of no other single dietary strategy that packs as much punch. This has become even more true over the past 20 years, ever since the dwarf variant of modern wheat has come to dominate.

2) Achieve a desirable 25-hydroxy vitamin D level--Contrary to the inane comments of the Institute of Medicine, vitamin D supplementation increases HDL, reduces small LDL, normalizes insulin and reduces blood sugar, reduces blood pressure, and exerts potent anti-inflammatory effects on c-reactive protein, matrix metalloproteinase, and other inflammmatory mediators. While we also have drugs that mimic some of these effects, vitamin D does so without side-effects.

3) Supplement omega-3 fatty acids from fish oil--Omega-3 fatty acids reduce triglycerides, accelerate postprandial (after-meal) clearance of lipoprotein byproducts like chylomicron remnants, and have a physical stabilizing effect on atherosclerotic plaque.

4) Normalize thyroid function--Start with obtaining sufficient iodine. Iodine is not optional; it is an essential trace mineral to maintain normal thyroid function, protect the thyroid from the hundreds of thyroid disrupters in our environment (e.g., perchlorates from fertilizer residues in produce), as well as other functions such as anti-bacterial effects. Thyroid dysfunction is epidemic; correction of subtle degrees of hypothyroidism reduces LDL, reduces triglycerides, reduces small LDL, facilitates weight loss, reduces blood pressure, normalizes endothelial responses, and reduces oxidized LDL particles.

5) Make exercise fun--Not just exercise for the sake of exercise, but physical activity or exercise for the sake of having a good time. It's the difference between resigning yourself to 30 minutes of torture and boredom on the treadmill versus engaging in an activity you enjoy and look forward to: go dancing, walk with a friend, organize a paintball tournament outdoors, Zumba class, plant a new garden, etc. It's a distinction that spells the difference between finding every excuse not to do it, compared to making time for it because you enjoy it.

Note what is not on the list: cut your fat, eat more "healthy whole grains," take a cholesterol drug, take aspirin. That's the list you'd follow if you feel your hospital needs your $100,000 contribution, otherwise known as coronary bypass surgery.

Topping up your vitamin D tank

22. January 2011 William Davis (17)
Now that my vitamin D replacement experience dates back nearly 5 years, I've been witnessing an unusual phenomenon:

The longer you take vitamin D, the less you need.

Let me explain. You take 10,000 units D3 in gelcap form. 25-hydroxy vitamin D levels, checked every 6 months, have remained consistently between 60 and 70 ng/ml. Three years into your vitamin D experience and 25-hydroxy vitamin D level rises to 98 ng/ml--an apparent need for less vitamin D.

So we cut your intake from 10,000 units per day to 8000 units per day. Another 25-hydroxy vitamin D level 6 months later: 94 ng/ml. We cut dose again to 6000 units, followed by another 25-hydroxy vitamin D level of 66 ng/ml.

This has now happened in approximately 20% of the people who have been taking vitamin D for 3 or more years. I know of no formal analysis of this effect, what I call the "topping up" phenomenon. Reasoned simply, it seems to me that, once your vitamin D "tank" is topped up (i.e., tissue stores have been replenished), it requires less to keep it full.

No one has experienced any adverse consequence of this topping up effect though it has potential for some people to develop toxic levels if 25-hydroxy vitamin D levels are not monitored long-term. In my office, I measure 25-hydroxy vitamin D levels every 6 months.

It means that long-term monitoring of 25-hydroxy vitamin D is crucial to maintain favorable and safe levels.

Thirteen catheterizations later

21. January 2011 William Davis (16)
When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

It started with chest pains at age 56, prompting her first heart catheterization that uncovered severe atherosclerotic blockages in all three coronary arteries. Her cardiologist advised a bypass operation.

Six months after the bypass operation, Janet was back with more chest pains, just as bad as before. Another heart catherization showed that two of the three bypass grafts had failed. The third bypass graft contained a severe blockage that required a stent, along with multiple stents in the two now unbypassed arteries.

In the ensuing 18 months, Janet returned for 8 additional catheterizations, each time leaving the hospital with one or more stents.

Janet's doctor was puzzled as to why her disease was progressing so aggressively despite Lipitor and the low-fat diet provided by the hospital dietitian. So he had Janet undergo lipoprotein testing (NMR):

LDL particle number: 3363 nmol/L
Small LDL particle number: 2865 nmol/L
HDL cholesterol: 32 mg/dl
Triglycerides: 344 mg/dl
Fasting blood glucose 118 mg/dl
HbA1c 5.8%

Unfortunately, Janet's doctor didn't understand what these values meant. He pretty much threw his arms up in frustration. That's when I met Janet.

From her lipoprotein panel and other values, it was clear to me that Janet was miserably carbohydrate-sensitive and carbohydrate-indulgent, as demonstrated by the extravagant quantity (2865 nmol/L) and proportion (2865/3363, or 85%) of small LDL, the form of LDL particles created by carbohydrate exposure. Janet struggled with depression over the years and had been using carbohydrate foods as "comfort" foods, often resorting to cookies, pies, cakes, breads, and other wheat-containing foods for emotional solace.

It took a bit of persuasion to convince Janet that it was low-fat, "healthy whole grains," as well as comfort foods, that had led her down this path. I also helped Janet correct her severe vitamin D deficiency, mild thyroid dysfunction, and lack of omega-3 fatty acids.

Since meeting Janet and instituting her new prevention program, she has undergone three additional catheterizations (performed by another cardiologist), all performed for chest pain symptoms that struck during periods of emotional stress. All showed . . . no significant blockage. (Apparently, the repeated "need" for stents triggered a Pavlovian response: chest pain = "need" for yet more stents.)

In short, correction of the causes of coronary atherosclerotic plaque--small LDL, vitamin D deficiency, omega-3 fatty acid deficiency, and thyroid dysfunction--and Janet's disease essentially ground to a halt.

Imagine, instead, that Janet had undergone 1) a heart scan to identify hidden coronary plaque 5-10 years before her first heart procedure, then 2) corrected the causes before they triggered symptoms and posed danger. She might have been spared an extraordinary amount of life crises, hospital procedures, expense (nearly $1 million), and emotional suffering.
