(Lack of ) Quality of nutritional supplements

In my last post, I blogged about how we must not confuse marketing with truth. They are often two different things.

A patient I saw today was absolutely convinced that his fish oil was the best available in the world: purer, uncontaminated by mercury or pesticides--"not like that other crap on the shelves." I asked him how he knew this. "They say so," he proudly declared.

Do you recognize this? He fell for the marketing. While there may be some truth in the manufacturer's claims, you can't believe it from the mouth of the manufacturer. True judgements about quality and purity have to come from an independent source like Consumer Reports, Consumer Lab, or the FDA.

But the FDA doesn't regulate the quality and purity of nutritional supplements. On the positive side, this has allowed supplement manufacturers to keep costs down, not having to navigate arcane and complex regulatory restrictions.

On the negative side, a fair number of supplement manufacturers get away with 1) producing supplements that fail to contain the stated amounts of ingredients, occasionally containing none of the essential ingredient(s), 2) contain contaminants like lead, and 3) make extravagant and often unfounded claims like "superior", "more effective", and "purer". (DHEA, for instance, is a particular landmine of poor quality. I recently suggested that a patient take DHEA; despite consistently taking 50 mg of a specific brand for several months, the blood level of DHEA-S didn't budge one bit--there was likely little or none in the capsule.)

The Fanatic Cook at http://fanaticcook.blogspot.com has posted some very insightful discussions on this issue and the proposed FDA regulations of supplements. They're worth perusing.

I really wish regulation weren't necessary and that the industry could have policed itself. But it clearly has failed and perhaps federal oversight is not such a bad thing, as long as the FDA regulations restrict themselves to oversight over quality and purity and not to efficacy. It's the efficacy regulation that could hogtie innovation in supplement development.

Marketing and truth are not the same

I often remind people: Don't confuse marketing with the truth.

Today, I spent a total of probably an hour and a half dissuading patients that some crazed piece of marketing trying to sell them something was not the same as truth.

I spent approximately 40 minutes alone with a woman who was absolutely convinced that:

--Nattokinase would cure her of all heart disease. It does not. Despite the promising health benefits of natto and vitamin K2 supplementation, nattokinase is a scam with no basis in science nor logic.

--Niacin destroys your liver and homeopathic remedies are superior. Quite simply, homeopathy = quackery. No rational thinking scientist endorses the utter nonsense practiced in this strange and outrageous set of practices that requires you to suspend all reason.

--Sufficient vitamin D is obtainable through a "potent" multivitamin. I know of no multivitamin preparation that even begins to provide the dose of vitamin D that is actually required by adults, nor is it absorbed since these D preparations are powder based.

--Fish oil will poison you with mercury. Accordingly, one brand of fish oil claims to be the only safe form. Those of you following these posts, or the reports of the USDA and FDA, as well as the reports of Consumer Reports and Consumer Lab (www.consumerlab.com) know that, unlike fish itself, there is no mercury in fish oil capsules.

--All coronary atherosclerotic heart disease is caused by heavy metal poisoning. Thus chelation with EDTA represents a cure for heart disease.


People are inundated with marketing that promise extravagant cures, remove need for any medication, make you smarter, sexier, thinner, and on and on.

If you see a TV ad for Ford that says they make the best cars in the U.S., do you immediately run out and put a For Sale sign on your GM car and buy a Ford? No, of course not. You recognize the ad for what it is: marketing. It may be true, but a TV commercial is not enough to convince you.

Then why would an ad promising extraordinary cures for cancer or heart disease convince you that this is true? It should not. Marketing ads should only serve to alert you to the possibility of value or benefit, but should never-- never--stand alone as proof. Take marketing for what it is: marketing of a product or service, not a scientific report, not a factual report, not news.

Marketing is advertising. Period.

More on erectile dysfunction

Several facts on erectile dysfunction and coronary plaque:


If you have erectile dysfunction, there's at least a 50% chance you also have coronary plaque.

If you have coronary plaque by a CT heart scan, there's a 50% chance you have erectile dysfunction.

If you have symptomatic coronary disease (chest pains, breathlessness, prior heart attack), there's a 90% chance you also have erectile dysfunction.


Coronary disease is characterized by a dysfunctional state of the "endothelium", or inner lining of the coronary arteries. Erectile dysfunction is characterized by dysfunction of the endothelium of the penile circulation. Same phenomenon, different territories. (There are other differences, of course, but the two conditions share this fundamental phenomenon.)


If you have any doubts about the physiologic effects of the supplement, l-arginine, just give it a try if you have erectile dysfunction. The erection enhancing effects alone should convince you that a genuine artery-dilating effect is exerted by this very powerful nutritional supplement.

If l-arginine fails by itself to restore full erectile capacity, there are additional strategies, both nutritional and medical, that you can consider.

Our newest Track Your Plaque Special Report on erectile dysfunction is coming out any day now.

High LDL cholesterol--only

As a sequel to my last post, just how often can we blame an isolated high LDL cholesterol as the cause of coronary plaque and a heart scan score?

In other words, how often does someone prove to have only LDL cholesterol as the cause of a heart scan score . . . and nothing else? No low HDL, small LDL, lipoprotein(a), a post-prandial (after-eating) intermediate-density lipoprotein, inflammatory responses, phospholipase A2, high triglycerides, vitamin D deficiency, etc.

Rarely. In fact, I can truly count the number of people who have only LDL cholesterol as their sole cause of coronary atherosclerotic plaque on one hand. It is really an infrequent situation.

Far more commonly, people have 5, 6, 7 or more reasons for coronary plaque.

Thus, the idea that a statin drug to reduce LDL will cure heart disease is completely folly. It does happen--but rarely. I think I've seen it happen twice. Much more commonly, a program that addresses all the causes of coronary plaque yields far superior benefits.

In my view, an effort to identify all the causes is relatively easy, makes far better sense, and provides you much greater assurance that you will succeed in conquering heart disease and removing its evil influence from your life.

Heart disease = statin deficiency

Judging from the conversations I hear from colleagues, what I hear from the media, and drug company advertising, you'd think that heart disease has one cause--a deficiency of statin drugs.

As their thinking goes, if you have coronary disease, you need a statin drug (Lipitor, Zocor, Crestor, pravachol, etc.). If you have progressive coronary disease, you need more statin drug. If you have a heart attack while on a statin drug, you need even more statin drug.

Some "experts" have even proposed that we do away with LDL cholesterol and we just give everybody a statin drug at high doses.

Does this make any sense to you?

Doesn't it make better sense that if someone has progressive heart disease or heart attack while on a statin drug, then target the other causes largely unaffected by a statin drug? Perhaps if LDL cholesterol remains high on the statin drug, then a higher dose is justified. But more often than not, it's not a high LDL on statin drugs that responsible, it's other causes. And there's many of them: low HDL, VLDL, IDL, Lp(a), deficiency of omega-3 fatty acids, inflammatory processes, vitamin D deficiency, among others. (An important exception to this is when the conventional calculated LDL substantially underestimates true LDL as measured by LDL particle number by NMR, apoprotein B, or 'direct' LDL.)

Imagine someone has pneumonia. After 2 weeks of antibiotics, they are only partly better. The solution: a higher dose of the same antibiotic--but never question if it was the right antibiotic in the first place. That's what is going on in heart disease.

The doctors have been brainwashed into believing this $22 billion dollar per year bit of propaganda. The drug companies actively try to recruit the public into believing the same. Don't fall for it.

The statin drugs do indeed have a role. But they are not the complete answer. More of the same when disease progresses makes no sense at all.

Fish oil and mercury

I often get questions about the mercury content in fish oil. I've even had patients come to the office saying their primary care doctor told them to stop fish oil to avoid mercury poisoning.

Manufacturers of fish oil also make claims that this product or that ("super-concentrated", "pharmaceutical grade", "purified", etc.) is purer or less contaminated than competitors' products. The manufacturers of the "drug" Omacor, or prescription fish oil, have added to the confusion by suggesting that their product is the most pure of all, since it is the most concentrated of any fish oil preparation (900 mg EPA+DHA per capsule). They claim that "OMACOR is naturally derived through a unique, patented process that creates a highly concentrated, highly purified prescription medicine. By prescribing OMACOR® (omega-3-acid ethyl esters), a prescription omega-3, your doctor is giving you a concentrated and reliable omega-3. Each OMACOR capsule contains 90% omega-3 acids (84% EPA/DHA*). Nonprescription omega-3 dietary supplements typically contain only 13%-63% EPA/DHA."

How much truth is there in these concerns?

Let's go to the data published by the USDA, FDA, and several independent studies. Let's add to that the independent (and therefore presumably unbiased) analyses provided by Consumer Reports and Consumer Labs (www.consumerlab.com). How much mercury has been found in fish oil supplements?

None.

This is different from the mercury content of whole fish that you eat. Predatory fish that are at the top of the food chain and consume other fish and thereby concentrate organic methyl mercury, the toxic form of mercury. Thus, shark, swordfish, and King mackerel are higher in mercury than sardines, herring, and salmon.

The mercury content of fish oil capsules have little to do with the method of processing and much more with the animal source of oil. Fish oil is generally obtained from sardines, salmon, and cod, all low in mercury. Fish oil capsules are not prepared from swordfish or shark.

Thus, concerns about mercury from fish oil--regardless of brand--are generally unfounded, according to the best information we have. Eating whole fish--now that's another story for another time. But you and I can take our fish oil to reduce triglycerides, VLDL, IDL, small LDL, and heart attack risk without worrying about mercury.

How much omega-3s are enough?

The basic dose we advocate for the Track Your Plaque program is 1200 mg per day of EPA + DHA, the essential omega-3 fatty acids.

1200 mg EPA+DHA is generally obtainable by taking 4 capsules of 1000 mg of fish oil, since the majority of preparations contain 180 mg EPA and 120 mg DHA per capsule.

But how will you know if a higher dose wouldn't be even better?

The principal parameter to look at is triglycerides. If triglycerides remain above 60 mg/dl, we usually consider increasing fish oil.

Another measure that's very important is intermediate-density lipoprotein, or IDL, also called "remnant lipoproteins" on a VAP panel. Persistence of any IDL or remnant lipoproteins is reason to consider more fish oil. Most commonly, if there is some persistence of either, we increase fish oil to 6000 mg per day of a standard preparation, or 1800 mg/day of EPA+DHA.

The only time we see persistence of IDL or remnant lipoproteins with this higher dose is when triglycerides are really high. If starting triglycerides are, for instance, 500 mg/dl, then even this higher dose may be insufficient. This is when more highly concentrated preparations of fish oil may be necessary, occasionally even the prescription form, Omacor. (We currently use Omacor only when high doses of EPA+DHA are required, most because of its outrageous cost. Two capsules per day costs around $120 per month; three capsules per day to provide 1800 mg/day of EPA+DHA costs $180 per month. I think this is outrageous and so we use it only when absolutely necessary.)

You might even argue that a higher dose of 1800 mg EPA+DHA, or 6000 mg of a standard capsule, might be preferable for more assured reduction of heart attack risk--even when triglycerides and IDL are perfectly under control. I wouldn't argue with you. But you won't observe any measurable feedback that tells you that a heightened effect is being obtained. I take that dose myself, in fact, despite the fact that elimination of wheat products and weight loss was sufficient to drop my triglycerides to the target level. I figure it's a small additional effort for added peace of mind.

Repentance for past sins

If you are new to the Track Your Plaque program and would like to jump start your effort, or if you are struggling with losing weight and excess weight is a part of the situation that created your CT heart scan score, then don't forget about fasting.

Fasting is the cessation of eating. However, recall from the Track Your Plaque Special Report, Fasting: Fast Track to Control Plaque at http://www.cureality.com/library/fl_04-012fasting.asp, there are many variations on fasting that permit some intake of healthy foods. (Thus, they are not, in the strict sense, "fasting". Accurate or no, there are variations that may be more palatable or do-able in the real world by real people.)

My personal favorite method to fast is to use a low-sugar, low-fat soy milk such as Light Silk, available at most major grocery stores. This high-protein, low-fat, low-sugar soy milk takes the edge off hunger and provides a minimal quantity of calories. A minimum of 72 hours is required for substantial results. (My one reservation about this brand of soy milk is that the Fanatic Cook claims that the manufacturer, Dean Foods, is a factory farm operation that abuses livestock--a discussion for another day.)

Fasting yields more than weight loss. It refreshes your appreciation for food. It reawakens you to the amount and quality of food you've been putting in your body. Fasting also allows you to recognize just how bad you might feel from the diet you were eating.

You also emerge from a fast with a reduced appetite and a renewed sense of appreciation for food. It makes the discipline of healthy eating a lot easier when you break your fast.

I tell people that fasting is not punishment. It is a form of enlightenment, of re-experiencing food and life. Fasting allows you to "catch up" on all the indiscretions you've been guilty of over the years.

It also provides enormous advantage in gaining control over coronary plaque.

A fanatic for Fanatic Cook

If you haven't already done so, I'd urge you to peruse the wonderfully insightful, sophisticated, and biting commentary provided by the Fanatic Cook Blog at http://fanaticcook.blogspot.com.

She (I assume it's a she) has been discussing the proposed Safe Food Act recently, an effort to address all the dangers in foods that have come to attention lately, like melamine in pet food and E. coli in bagged spinach. Her most recent post is:

Nebraska Farm Bureau Thinks Food Safety Act Bad Idea, the latest in a series of posts exploring this issue.

I'd like to know who the Fanatic Cook is, or "Bix" as she calls herself. (I assume it's a "she" but I don't really know that for a fact.) I've corresponded with her and she prefers to remain anonymous for unspecified reasons. I'd like to know who this person is both for a more secure sense of credibility, as well as I'd simply like to know who can write so intelligently and why. I suspect that she's a professional nutrition scientist or something along those lines, since the level of insight into many scientific issues is quite impressive. Her Blogs will make great material for a book, if compiled and organized. Watch out for this one.

Erectile dysfunction and coronary plaque

Erectile dysfunction (ED), previously known as "impotence," and coronary atherosclerotic plaque go hand in hand.

A recent study in men with advanced coronary disease showed that 93% experienced ED. The participants in the Track Your Plaque program, for the most part, do not have advanced coronary atherosclerosis, but have an earlier form detected by a CT heart scan.

What proportion of men with asymptomatic coronary plaque as measured by a CT heart scan have ED? Around 50%. In other words, it's not a rare occurrence.

The conversation about ED (and even its renaming from impotence) really gained momentum with the development of ED-drugs like Viagra and Cialis. The drugs are reasonably effective and safe. However, you will hear little about all the strategies that can either precede your need for these drugs and/or enhance your response to these drugs if the response is partial. That part of the conversation, of course, doesn't yield loads of drug company revenues.

One of the most helpful and specific nutritional supplements available that can partially restore the nitric oxide-deficiency of ED is l-arginine. L-arginine is the body's source of nitric oxide (NO), the master dilator (relaxing agent) for all arteries of the body. NO dilates penile arteries, it dilates coronary arteries. Lack of NO disables the penile capacity for erection and encourages growth of coronary atherosclerotic plaque. Track Your Plaque Members are already familiar with l-arginine as a facilitator of coronary plaque regression.

We will detail the supplements that you can use safely in your Track Your Plaque program to both enhance erectile function if you suffer ED, as well as impact positively on coronary health, in an upcoming and detailed Special Report on the www.cureality.com website.

Take a niacin "vacation"

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

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


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

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.

No flush = No effect



"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan


Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.
