If you'd like to reduce LDL cholesterol with nearly as much power as a statin drug, think thyroid.

When thyroid is corrected to ideal levels, LDL cholesterol drops 20, 30, 40 mg/dl or more, depending on how poor thyroid function and how high LDL are at the start. The poorer the thyroid function (the higher the TSH or the lower the T3 and T4) and the higher the LDL cholesterol, the more LDL drops with thyroid correction.

(For those of you minding LDL particle size, such as Track Your Plaque Members, the "dominant" LDL species will drop: If you are genetic small LDL, small LDL will drop. If you have mostly large LDL because of being wheat-free and sugar-free, then large LDL will drop.)

One of the problems is that many healthcare providers blindly follow what the laboratory says is "normal" or the "reference range," which is usually nothing more than a population average (actually the mean +/- 2 standard deviations, a common method of developing references ranges). In other words, a substantial degree of low thyroid function, or hypothyroidism, can be present when your doctor adheres to the reference range provided by the laboratory.

What does it mean to achieve ideal thyroid status? My list includes:

--Normal oral temperature of 97.3 F first upon arising. (The thyroid is the body's thermoregulatory organ.)
--TSH 1.0 mIU/L or less
--Free T3 upper half "normal" range
--Free T4 upper half "normal" range
--You feel good: mental clarity, energy, upbeat mood. You lose weight when you try.

Iodine replacement should be part of any thyroid health effort. Iodine is not an optional trace mineral, no more than vitamin C is optional (else your teeth fall out). The only dangers to iodine replacement are to those who have been starved of iodine for many years; increase iodine and the thyroid can over-respond. I've seen this happen in 2 of the last 300 people who have supplemented iodine.

In my view, neglecting T3 replacement is absurd. While it is not clear to me why many otherwise healthy people have low T3 at the low range of "normal" or even in the below-normal range, people feel better and have better health--faster weight loss, reduced LDL, reduced triglycerides, they are happier and enjoy more energy--when T3 is increased to the upper half of the reference range. (Crucial question: Why is the 5'-deiodinase enzyme that converts T4 to T3 inhibited, resulting in reduced free T3? What is in our diets or environment that is exerting this effect? I don't have answer, but we sorely need one.)

It pays to be a perfectionist when it comes to thyroid. Not only do you feel better, but LDL cholesterol can drop with a statin-like magnitude, but with none of the adverse effects.

If interested, Track Your Plaque offers fingerstick blood spot testing that you can perform in your own home. Each test kit will test for: TSH, free T3, free T4, along with a thyroid peroxidase antibody (a marker for Hashimoto's thyroiditis, an autoimmune inflammatory condition of the thyroid).

What do you think of these chains of logic?

Cyanide is a potent lethal poison; carbon monoxide is a less lethal poison.
Therefore: plenty of carbon monoxide is good.

Having uterine cancer is a bad thing. Having uterine fibroids is a less bad thing.
Therefore: plenty of uterine fibroids are good.

These are obvious examples of seriously flawed logic. Students of logic and philosophy will recognize the above erroneous sequences as examples of the twisted arguments often used to persuade an argumentative opponent of the logic of a premise. As long ago as 335 B.C., Greek philosopher, Aristotle, recognized the pitfalls of thinking in such arguments. You think we’d know better by now.

Try this one:

White enriched flour is a bad for health; whole grains are less bad for health.
Therefore: plenty of whole grains are good for health.

Ouch!

In the 1960s, we all ate hot dogs on white buns, white flour Wonder Bread® sandwiches, Mom made cookies and cupcakes with white flour. Then, during the 1970s and 1980s, clinical studies were performed demonstrating that whole wheat and whole grains reduced colon cancer, high blood pressure, diabetes, and heart disease compared to white flour. In other words, add back fiber and B vitamins and health benefits develop: No argument here.

Therefore: whole grains must be good for health. Further, lots of whole grains?unlimited quantities of whole grains many times per day, every day?must be even better. Even the USDA says so on their nutrition pyramid, with 8-11 servings of grains per day, 4 of which should be whole grains, at the widest portion of the pyramid.

But what happens when you follow this logic through and fill your diet with whole grains?

Look around you and it’s easy to see: Appetite increases, people become obese, blood sugar increases, diabetes develops, HDL cholesterol plummets, triglycerides skyrocket, inflammatory patterns (e.g., c-reactive protein, or CRP) increase, small LDL (the number one cause for heart disease in the obese U.S.!) shoots through the roof.

I would no more fill my diet with “healthy whole grains” than I would close my garage door with the car running.

Pomegranate juice, 8 oz:

Sugars, total 31.50 g

Sucrose 0.00 g

Glucose (dextrose) 15.64 g

Fructose 15.86 g

In your quest to increase the flavonoids in your diet, do you overexpose yourself to fructose?

Remember: Fructose increases LDL cholesterol, apoprotein B, small LDL, triglycerides, and substantially increases deposition of visceral fat (fructose belly?). How about a slice of whole grain bread with that glass of pomegranate juice? The Heart Association says it's all low-fat!

Another in a series of data extrapolations that attempt to predict long-term cancer risk from medical radiation exposure was published in the July 13, 2009 Archives of Internal Medicine, viewable here.

Over the years, I've fussed about the radiation dose used by some centers for CT heart scans. (Note: I'm talking about CT heart scans, not CT coronary angiograms, an entirely different test with different radiation exposure.) In the "old" days, when electron-beam devices (EBT) were the best on the block, the old single-slice CT scanners (the predecessor of the current 64-slice MDCT scanners) exposed patients to ungodly quantities of radiation, while the EBT devices required very small quantities (0.5 mSv or about the equivalent of 4 standard chest x-rays or one mammogram).

But CT technology has advanced considerably. While EBT has been phased out (although it was an exceptional technology, GE acquired the small California manufacturer, then promptly scrapped the operation; you can guess why), multi-detector CT (MDCT) technology has improved in speed, image quality, and radiation exposure.

While it has improved, radiation exposure still remains an issue. The authors of the study applied the scanning protocols used at three hospitals and those in several CT heart scan studies, then calculated radiation exposure. They found a more than ten-fold range of exposure, from 0.8 mSv to 10.5 mSv. (All scanners were MDCT, none EBT.)

That's precisely what I've been worrying about: In the rapid rush to develop new devices, radiation exposure has often been a neglected issue. While some scan centers do an excellent job and take steps to minimize exposure, others barely lift a finger and consequently expose their patients to unnecessary radiation.

However, it's not as bad as it sounds. For one, the study included 16-slice MDCT scanners, a scanner type that I warned people to not use because of radiation. On the current most popular 64-slice devices, much lower radiation exposure is possible, on the order of 0.8-1.2 mSv routinely--if the center takes the effort.

This study, while eye-opening, will achieve some good: CT heart scans are here to stay. But the day-to-day practice of heart scanning should be:

1) standardized
2) conducted with radiation exposure as low as possible, preferably <0.8 mSv

To read more about this issue, below I've reprinted a 2007 full Track Your Plaque Special Report, CT Heart Scans and Radiation: The Real Story.

CT heart scans and radiation: The real story

“My personal opinion is that many patients today who are receiving multiple CT scans may well be getting at least comparable doses to subjects that have now developed malignancies from x-ray radiation received in the 1930s and '40s. And, similar to those days when the doses were unknown, the dose that patients receive today over a course of years of multiple CT scans is also completely unknown . . .

“I recommend that all healthcare providers become familiar with the concept that 1 in 1000 CT studies of the chest, abdomen, or pelvis may result in cancer.”

Is this just hype to generate headlines? Or is the truth buried in the enormous marketing clout of the medical device industry, among which the imaging device manufacturers reign supreme?

It’s been over 110 years since radiation was first used for medical imaging. Over those years, it has had its share of misadventures.

In the 1930s and 1940s, before the dangers of radiation were recognized, shoe shoppers had shoes fitted using an x-ray device of the foot to assess fit. High doses of radiation were used to shrink enlarged tonsils and extinguish overactive thyroid glands. Attitudes towards radiation were so lax that doctors commonly permitted themselves to be exposed without protection day after day, year after year, until an unexpected rise in blood cancers like leukemia was observed. As recently as the 1970s and 1980s, cancers like Hodgkins’ disease were treated with high doses of radiation, also leading to radiation-induced diseases decades later.

Not all radiation is bad. Radiation can also be used as a therapeutic tool and even today remains a useful and reasonably effective method to reduce the size, sometimes eliminate, certain types of cancer. Forty percent of people with cancer now receive some form of radiation as part of their treatment (Ron E 2003).

Just how much does medical radiation add to our exposure?

Estimates vary, but most experts estimate that medical imaging provides approximately 15% of total lifetime exposure. In other words, radiation exposure from medical imaging is simply a small portion of total exposure that develops over the years of life. Exposure can be much higher, however, in a specific individual who undergoes repeated radiation imaging or treatment of one sort or another.

For all of us, exposure to medical radiation is part of lifetime exposure from multiple sources, added to the radiation we receive from the world around us. Just by living on earth, we are exposed to radiation from space and naturally-occurring radioactive compounds, and receive somewhere around 3.0 mSv per year (U.S. Nuclear Regulatory Commission). (Doses for radiation exposure are commonly expressed in milliSieverts, mSv, a measure that reflects whole-body radiation exposure.) People living in high-altitude locales like Colorado get exposed to an additional 30–50% ambient radiation (1.0–1.5 mSv more per year).

Much of the information on radiation exposure comes from studies like the Life Span Study that, since 1961, has tracked 120,000 Japanese exposed to radiation from the atomic bombs dropped in 1945 (Preston DL et al 2003). Although regarded as a high-dose exposure study for obvious reasons, there are actually thousands of people in this study who were exposed to lesser quantities of radiation (because of distance from the bomb sites) who still display a “dose-response” increased risk for cancer many years later in life. Radiation exposures of as little as 5–20 mSv showed a slight increase in lifetime risk.

Occupational and excessive medical exposure to radiation also provides a “laboratory” to examine radiation risk. Miners exposed to radon gas; patients exposed to the imaging agent, Thorotrast, containing radioactive isotope thorium dioxide and used as an x-ray contrast agent in the 1930s and 1940s and possesses the curious property of lingering in the body for over 30 years after administration; radium injections administered between 1945 and 1955 to treat diseases like ankylosing spondylitis and tuberculosis, all provide researchers an opportunity to study the long-term effects of various types of radiation exposure over many years (Harrison JD et al 2003).

The excess exposure of workers and several hundred thousand nearby residents to the Mayak nuclear plant in Russia has also revealed a “dose-response” relationship, with increasing exposure leading to more cancers, including leukemia and solid cancers of the bone, liver, and lung (Shilnikova NS et al 2003). Nuclear waste released into the Techa river between 1948 and 1956 contaminated drinking water used by over 100,000 Russians. A plant explosion in 1957 also released an excess of radiation into the atmosphere, yielding exposure via inhalation. Some sources estimate that at least 272,000 people have been affected by radiation from the Mayak plant. This unfortunate situation has, however, yielded plenty of data on radiation exposure and its long-term effects.

It’s also been known for several decades that people who receive therapeutic radiation for treatment of cancer, even with the reduced doses now employed, are subject to increased risk of a second cancer consequent to the radiation treatment.

From experiences like this, radiation experts estimate that an exposure of 10 mSv increases a population’s risk for cancer by 1 in 1000 (Semelka RC et al 2007).

This question was recently thrust into the spotlight with publication of a study from Columbia University in New York suggesting that a 20-year old woman would be exposed to a lifetime risk of cancer as high as 1 in 143 consequent to the radiation received during a CT coronary angiogram. (Important note: This was estimated risk from a CT coronary angiogram, not a simple heart scan that we advocate for the Track Your Plaque program.) The risk at the low end of the spectrum would be in an 80-year old man (because of the shorter period of time to develop cancer), with a risk of 1 in 5017. If “gating” to the EKG is added (which many scan centers do indeed perform nowadays), risk for a 60-year old woman is estimated at 1 in 715; risk for a 60-year old male, 1 in 1911 (Einstein AJ et al 2007). This study generated some criticism, since it did not directly involve human subjects, but used “phantoms” or x-ray dummies to simulate x-ray exposure. Nonetheless, the point was made: CT coronary angiograms in current practice do indeed expose the patient to substantial quantities of radiation, sufficient to pose a lifetime risk of cancer.

The media frenzy

The NY Times ran an article called With Rise in Radiation Exposure, Experts Urge Caution on Tests in which they stated:

"According to a new study, the per-capita dose of ionizing radiation from clinical imaging exams in the United States increased almost 600 percent from 1980 to 2006. In the past, natural background radiation was the leading source of human exposure; that has been displaced by diagnostic imaging procedures, the authors said."

“This is an absolutely sentinel event, a wake-up call,” said Dr. Fred A. Mettler Jr., principal investigator for the study, by the National Council on Radiation Protection. “Medical exposure now dwarfs that of all other sources.”

Radiation is a widely used imaging tool in medicine. Although CT scans of the brain, bones, chest, abdomen, and pelvis account for only 5% of all medical radiation procedures, they are responsible for nearly 50% of medical radiation used. It’s been known for years that increasing radiation exposure increases cancer risk over many years, but the boom of newer, faster devices that provide more detailed images has opened the floodgates to expanded use of CT scanners.

But before we join in the hysteria, let's first take a look at exposure measured for different sorts of tests:

Typical effective radiation dose values for common tests

Computed Tomography

Head CT 1 – 2 mSv
Pelvis CT 3 – 4 mSv
Chest CT 5 – 7 mSv
Abdomen CT 5 – 7 mSv
Abdomen/pelvis CT 8 – 11 mSv
Coronary CT angiography 5 – 12 mSv

Non-CT

Hand radiograph Less than 0.1 mSv
Chest radiograph Less than 0.1 mSv
Mammogram 0.3 – 0.6 mSv
Barium enema exam 3 – 6 mSv
Coronary angiogram 5 – 10 mSv
Sestamibi myocardial perfusion (per injection) 6 – 9 mSv
Thallium myocardial perfusion (per injection) 26 – 35 mSv

Source: Cynthia H. McCullough, Ph.D., Mayo Clinic, Rochester, MN

A plain, everyday chest x-ray, providing less than 0.1 mSv exposure, provides about the same quantity of radiation exposure as flying in an airplane for four hours, or the same amount of radiation from exposure to our surroundings for 11–12 days. Similar exposure arises from dental x-rays.

If you have a heart scan on an EBT device, then your exposure is 0.5-0.6 mSv, roughly the same as a mammogram or several standard chest x-rays.

With a heart scan on a 16- or 64-slice multidetector device, exposure is ideally around 1.0-2.0 mSv, about the same as 2-3 mammograms, though dose can vary with this technology depending on how it is performed (gated to the EKG, device settings, etc.)

CT coronary angiography presents a different story. This is where radiation really escalates and puts the radiation exposure issue in the spotlight. As Dr. Cynthia McCullough's chart shows above, the radiation exposure with CT coronary angiograms is 5-12 mSv, the equivalent of 100 or more chest x-rays or 20 mammograms. Now, that's a problem.

The exposure is about the same for a pelvic or abdominal CT. The problem is that some centers are using CT coronary angiograms as screening procedures and even advocating their use annually. This is where the alarm needs to be sounded. These tests, as wonderful as the information and image quality can be, are not screening tests. Just like a pelvic CT, they are diagnostic tests done for legitimate medical questions. They are not screening tests to be applied broadly and used year after year.

It’s also worth giving second thought to any full body scan you might be considering. These screening studies include scans of the chest, abdomen, and pelvis. These scans, performed for screening, expose the recipient to approximately 10 mSv of radiation (Radiological Society of North American, 2007). Debate continues on whether the radiation exposure is justified, given the generally asymptomatic people who generally undergo these tests.

Always be mindful of your radiation exposure, as the NY Times article rightly advises. However, don't be so frightened that you are kept from obtaining truly useful information from, for instance, a CT heart scan (not angiography) at a modest radiation cost.

Heart scans, CT coronary angiograms and the future

Unfortunately, practicing physicians and those involved in providing CT scans are generally unconcerned with radiation exposure. The majority, in fact, are entirely unaware of the dose of radiation required for most CT scan studies and unaware of the cancer risk involved. It is therefore up to the individual to insist on a discussion of the type of scanner being used, the radiation dose delivered (at least in general terms), the necessity of the test, alternative methods to obtain the same diagnostic information, all in the context of lifetime radiation exposure.

Our concerns about radiation exposure all boil down to concern over lifetime risk for cancer, a disease that strikes approximately 20% of all Americans. Many factors contribute to cancer risk, including obesity, excessive saturated fat intake, low fiber intake, lack of vitamin D, repeated sunburns, excessive alcohol use, smoking, exposure to pesticides and other organochemicals, asbestos and other industrial exposures, electromagnetic wave exposure, and genetics. Radiation is just one source of risk, though to some degree a controllable one.

Some people, on hearing this somewhat disturbing discussion, refuse to ever have another medical test requiring radiation. That’s the wrong attitude. It makes no more sense than wearing lead shielding on your body 24 hours a day to reduce exposure from the atmosphere. Taken in the larger context of life, radiation exposure is just one item on a list of potentially harmful factors.

It is, however, worth some effort to minimize radiation exposure over your lifetime, particularly before age 60, and by submitting to high-dose testing only when truly necessary, or when the potential benefits outweigh the risks. Thus, with heart scans and CT coronary angiography, some thought to the potential benefits of knowing your score or the information gained from the CT angiogram need to be considered before undergoing the test. Often the practical difficulty, of course, is that your risk for heart disease simply cannot be known until after the test.

In our view, in the vast majority of instances a simple CT heart scan can serve the simple but crucial role of quantifying risk for heart attack and atherosclerotic plaque. CT heart scans yield this information with less than a tenth of the radiation exposure of a CT coronary angiogram. In people without symptoms and a normal stress test, there is rarely a need for CT coronary angiography with present day levels of radiation exposure. Perhaps as technology advances and the radiation required to generate images is reduced, then we should reconsider.

Early experiences are suggesting that the newest 256-slice scanners, now being developed but not yet available, will cut the dose exposure of 64-slice CT angiograms in half (from 27.8 mSv to 14.1 mSv in a recent Japanese study). The 256-slice scanners will allow scanning that is faster over a larger area in a given period of time.

Thankfully, the scanner manufacturers are increasingly sensitive to the radiation issue and have been working on methods to reduce radiation exposure. However, it still remains substantial.

A carefully-conducted study by a collaborative research group at University of California-Berkeley has finally closed the lid on the fuss over fructose vs. glucose and its purported adverse effects.

The study is published in its entirety here.

Compared to glucose, fructose induced:

1) Four-fold greater intra-abdominal fat accumulation--3% increased intra-abdominal fat with glucose; 14.4% with fructose. (Intraabdominal fat is the variety that blocks insulin responses and causes diabetes and inflammation.)

2) 13.9% increase in LDL cholesterol but double the increase for Apoprotein B (an index of the number of LDL particles, similar to NMR LDL particle number).

3) 44.9% increase in small LDL, compared to 13.3% with glucose.

4) While glucose (curiously) reduced the net postprandial (after-eating) triglyceride response (area under the curve, AUC), fructose increased postprandial triglycerides 99.2%.

The authors propose that fructose specifically increases liver VLDL production, the lipoprotein particle that yields abnormal after-eating particles, increased LDL, and provides building blocks to manufacture small LDL particles. The authors also persuasively propose that fructose metabolism, unlike glucose, is not inhibited (via feedback loop) by energy intake, i.e., it's as if you are always starving.

Add to this the data that show that fructose increases uric acid (that causes gout and may act as a coronary risk factor), induces leptin resistance, causes metabolic syndrome (pre-diabetes), and increases appetite, and it is clear that fructose is yet another common food additive that, along with wheat, is likely a big part of the reason Americans are fat and diabetic.

Fructose is concentrated, of course, in high-fructose corn syrup, comprising anywhere from 42-90% of total weight. Fructose also composes 50% of sucrose (table sugar). Fructose also figures prominently in many fruits; among the worst culprits are raisins (30% fructose) and honey (41% fructose).

Also, beware of low-fat or non-fat salad dressings (rich with high-fructose corn syrup), ketchup, beer, fruit drinks, fruit juices, all of which are rich sources of this exceptionally fattening, metabolism-bypassing, LDL cholesterol/small LDL/ApoB increasing compound. Ironically, this means that many low-fat foods meant to reduce cholesterol actually increase it when they contain fructose in any form.

When you hear or say "fructose," run the other way, regardless of what the Corn Refiners Association says.

Matt came to me because his doctor couldn't reduce his LDL cholesterol.

His doctor had prescribed Zocor (simvastatin), Lipitor, Crestor, even pravastatin, all of which resulted in incapacitating muscle aches and weakness within a week of starting. No surprise, Matt had a jaundiced view of statin drugs.

We started out by characterizing his lipoprotein patterns:

--LDL 155 mg/dl

--72% of LDL was small LDL, a moderately severe pattern. (This means that small LDL comprised 112 mg/dl of the total 155 mg/dl LDL; large LDL comprised 43 mg/dl--small LDL was the problem.)

--HDL 42 mg/dl --Triglycerides 133 mg/dl

--No lipoprotein(a)

Beyond lipoproteins, Matt proved severely deficient in vitamin D with a starting level of 18 ng/ml.

Matt's doctor had advised that he avoid salt, as his blood pressure had been borderline high. His thyroid assessment disclosed a TSH of 3.89 mIU/ml with thyroid hormones free T3 and free T4 in the lower half of the normal range.

I therefore asked Matt to:

--Eliminate wheat, cornstarch, and sugars to reduce small LDL
--Add iodine
--Supplement 6000 units of an oil-based vitamin D preparation
--Take fish oil to provide at least 1800 mg EPA + DHA per day
--Take Armour Thyroid 1 grain per day

Several months later on this program, Matt had a repeat basic lipid panel:

--LDL 82 mg/dl--a 47% reduction

--HDL 52 mg/dl a 24% increase

--Triglycerides 60 mg/dl--a 55% decrease

In addition, vitamin D was 66 ng/ml, TSH was <1.0 mIU/ml with free T3 and free T4 in the upper half of the "reference range." Matt also felt great.

While the numbers could be slightly better, Matt had made tremendous progress towards achieving perfect values.

There you have it: Marked correction of cholesterol values, no statin drugs involved.

Even if you’re not interested in building big muscles like a bodybuilder, there are health benefits to increasing muscle mass: increased bone density, better balance, and fewer injuries. Greater muscle mass means higher metabolic rate, improved insulin responsiveness, lower blood sugar. The inevitable loss of muscle mass of aging can lead to frailty, an increasingly common situation for the elderly. Muscle loss be reversed, health improved as a result.

Since its introduction in 1994, creatine has exploded in popularity, particularly among bodybuilders and athletes interested in gaining muscle mass and strength. But creatine is not just for young weight lifters. If you are just interested in increasing muscle mass for its health benefits, then creatine is something to consider.

A study of creatine supplementation in men, average age 70 years, demonstrated that, when creatine was combined with strength training, it increased muscle mass 250% better than placebo (7.26 lb muscle vs 2.86 lb muscle), along with improved leg strength and endurance. The same group also demonstrated 3.2% increased bone density (measured using dual energy X-ray absorptiometry) after 12 weeks in participants taking creatine with strength training, while the control (no strength training, no creatine) group decreased by 1.0%.

Benefits are not confined to men. Similar results were observed in another study that included women (age 65 and older), with outcomes in females comparable to males. This is especially important for females, given the common development of osteopenia and osteoporosis in postmenopausal females.

Other studies have shown that benefits are maintained after stopping creatine supplementation.

The most popular form of creatine is the monohydrate, generally taken as a “loading” phase of 15-20 grams per day (generally split into 3-4 doses of 5 grams) for 5-7 days, followed by weeks to months of 2-5 grams per day.

An alternative form, polyethylene glycosylated creatine (PEG-creatine) provides similar effects at one-fourth to one-half the dose of creatine, i.e., 1.25-2.5 grams per day.

Despite previous concerns about kidney toxicity with prolonged use, another study showed that athletes taking creatine for up to 21 months have shown no adverse effects on kidney function, lipid (cholesterol) values, or other basic health measures.

Having healthy muscle mass doesn't make you bulge like a bodybuilder. With modest efforts at strength training, augmented with creatine supplementation, you have a wonderful tool to feel better, reduce injury, increase bone density, and combat abnormal insulin resistance, not to mention accelerate weight loss, since lean muscle mass consumes energy.

There has been a lot of debate over whether or not “bio-identical” hormones, i.e., hormones identical to the human form, are superior to non-human forms dispensed by the drug industry.

The FDA is currently taking steps to clamp down on availability of bioidentical hormones and their claims of superiority, despite a groundswell of grassroot support for them. The argument has pitted anti-aging practitioners and the public, as well as the likes of Oprah and Suzanne Somers, against Big Pharma and the FDA, the two forces trying to squash the bioidentical hormone movement.

Regardless of what heavy-handed approach the FDA takes, we already have access to hormones identical to the original human form. It requires no prescription and yields downstream hormones that the human body recognizes as human.

That "bioidentical" hormone is pregnenolone.

Pregnenolone is the first biochemical step in the conversion of dietary cholesterol (yes-cholesterol!) to numerous other hormones. Pregnenolone is the source of the hormones that lie at the center of the bioidentical hormone controversy: estrogens, progesterone, and testosterone. We therefore already have our own over-the-counter, non-prescription form of bioidentical hormones.

Supplemental pregnenolone increases estrogens (mildly), progesterone, and testosterone. Prenenonlone supplementation simply provide more of the basic substrate for hormone production. The increase in hormones is usually modest, not as vigorous as direct hormone replacement like, say, testosterone or progesterone topical creams. But pregnenolone can be useful when small to moderate increases are desired, such as for reduction of Lp(a). A theoretical downside is that pregnenonlone can also convert to cortisol, the adrenal gland hormone that regulates fluid and blood pressure. However, I've not seen any measurable increase in cortisol with low doses of pregnenonlone and limited data suggest that it does not. Pregnenolone also converts to the other adrenal gland hormone, DHEA; I call DHEA "the hormone of assertiveness," since some people who take too much pregnenolone (or direct DHEA) acquire excessive assertiveness.

The key to pregnenolone supplementation is to proceed gradually and begin with a small dose, e.g., 5 mg every morning. Hormonal assessment is best conducted periodically to assess the effects and to determine whether a dose adjustment is in order.

With the assistance of dietitian and health educator, Margaret Pfeiffer,MS RD CD, author of Smart 4 Your Heart and very capable chef and breadmaker (previously, before she gave up wheat), we made a loaf of bread using Eli Rogosa's einkorn wheat. Recall that einkorn wheat is the primordial 14-chromosome wheat similar to the wild wheat harvested by Neolithic humans and eaten as porridge.

The essential question: Has wheat always been bad for humans or have the thousands of hybridization experiments of the last 50 years changed the structure of gluten and other proteins in Triticum aestivum and turned the "staff of life" into poison? I turn to einkorn wheat, the "original" wheat unaltered by human manipulations, to figure this out. While einkorn wheat is still a source of carbohydrates, is it something we might indulge in once in a while without triggering the adverse phenomena associated with modern wheat?

Here's what we did:

This is the einkorn grain as we received it from Eli's farm. This was enough to make one loaf (approximately 3 cups).

The einkorn grain is a dark golden color. I tried chewing them. They taste slightly nutty. They soften as they sit in your mouth.

Here's Margaret putting the einkorn grain into the electric grinder.

We tried to grind the grain by hand with mortar and pestle, but this proved far more laborious than I anticipated. After about 15 minutes of grinding, this is what I got:

Barely 2 tablespoons. That's when Margaret fired up the electric grinder. (I can't imagine having to grind up enough flour by hand for an entire family. Perhaps that's why ancient cultures were thin despite eating wheat. They were just exhausted!)

We added water, salt, and yeast, then put the mix into an electric breadmaker to knead the dough and keep it warm.

We let the dough rise for 90 minutes, much longer than conventional dough. The einkorn dough "rose" very little. Margaret tells me that most dough made with conventional flour rises to double its size. The einkorn dough increased no more than 20-30%.

The einkorn dough also distinctly smelled like peanut butter.

After rising, we baked the dough at 350 degrees F for 30 minutes. This is the final product.

Because I want to gauge health effects, not taste, the bread we made had no added sugar or anything else to modify taste or physiologic effect.

On first tasting, the einkorn bread is mildly nutty and heavy. It had an unusual sour or astringent taste at the end, but overall tasted quite good.

Next: What happens when we eat it? I'm going to give the einkorn bread (I've got to make some more) to people who experience acute reactions to conventional wheat and see if the einkorn does the same. I will also assess blood sugar effects since, after all, hybridizations or no, it is still a carbohydrate.

Margaret Pfeiffer's book is available on Amazon:

Some people are reluctant to give up wheat because it is talked about in the Bible. But the wheat of the Bible is not the same as the wheat of today. (See In search of wheat and Emmer, einkorn and agribusiness.) Comparing einkorn to modern wheat, for example, means a difference of chromosome number (14 chromosomes in einkorn vs. 42 chromosomes in modern strains of Triticum aestivum), thousands of genes, and differing gluten content and structure.

How about Ezekiel bread, the sprouted wheat bread that is purported to be based on a "recipe" articulated in the Bible?

Despite the claims of lower glycemic index, we've had bad experiences with this product, with triggering of high blood sugars, small LDL, and triglycerides not much different from conventional bread.

David Rostollan of Health for Life sent me this interesting perspective on Ezekiel bread from an article he wrote about wheat and the Bible. David argues that the entire concept of Ezekiel bread is based on a flawed interpretation.

"I Want to Eat the Food in the Bible."

Are you sure about that?

Some people, still wanting to be faithful to the Bible, will discard the "no grain/wheat" message on the basis of biblical example. After all, God told Ezekiel to make bread, he gave the Israelites "bread from heaven," and then Jesus (who is called the "Bread of Life"!) multiplied bread, and even instituted the New Covenant with what? Bread and wine! If you're going to live the Bible, it seems that bread and/or wheat is going to play a part.

But this is unnecessary. Sure, the Bible can and does tell us how to live, but this doesn't mean that everything in the Bible is meant to be copied verbatim. Applying the Bible to our lives requires wisdom, not a Xerox machine.

The Bible was written in a historical context, and the setting happened to be an agricultural one. Because of this, the language used to describe blessing spoke of things like fields full of grain, or barns overflowing with wheat. Had the Bible been written in the context of a hunter-gatherer culture, the language describing blessing probably would have been about the abundance of wild game, or baskets full of vegetables. Whatever is most valuable in your time and in your culture is a blessing. God accommodated His message to the culture as it existed at the time. This is done throughout Scripture.

There is a danger, then, in merely copying what the Bible says, instead of extracting the principles by which to live. Take the above example of Ezekiel, for instance. There's a whole product line in health food stores called "Ezekiel Bread" that supposedly copies the recipe given in Ezekiel 4:9. This is from the website:

"Inspired by the Holy Scripture verse Ezekiel 4:9., 'Take also unto thee Wheat, and Barley, and beans, and lentils, and millet, and Spelt, and put them in one vessel, and make bread of it...'"

Believing that this "recipe" has some kind of special power just because it's in the Bible is ridiculous. How ridiculous is it? I'll tell you in a moment, but first let me say that this is why it's so important not to confuse descriptives with prescriptives. Is the Bible telling a story, or is it telling us to do something? We would be well-advised not to confuse the two.

In the case of the Ezekiel Bread, what is going on in the passage? There's a siege going on, with impending famine, and Ezekiel is consigned to eating what was considered back then to be some of the worst possible food. It was basically animal chow. But that's not the worst thing going on in this passage. Apparently, when the makers of Ezekiel Bread were gleaning their inspiration for the perfect recipe, they stopped short
of verse 12:

"And thou shalt eat it as barley cakes, and thou shalt bake it with dung that cometh out of man, in their sight."

Um...what? Well, there was a good reason for this. God was judging His people, and by polluting this really bad bread with dung (which was a violation of Mosaic law; Lev. 5:3), He was saying that they were no different from the unclean Gentiles.

So why would we take this story and extrapolate a bread recipe from it? Beats me. If you were going to be consistent, though, here's what you'd have to end up with:

Let that be a lesson to you. We don't just go and do everything that we see in the Bible.

I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March.

Dr. Fox is quiet and unassuming, but had incredible things to say about his experience with carbohydrate restriction in female infertility and pregnancy. While readers of The Heart Scan Blog already know that I advocate a diet free of wheat, cornstarch, and sugar for heart health and correction of multiple lipoprotein abnormalities, it was fascinating to hear how a similar approach seems to yield extraordinary benefits in this entirely unrelated area of female health. Obviously, female infertility and pregnancy are unrelated to heart health, but the extraordinary benefits witnessed by Dr. Fox in this area suggest that some fundamental lessons in human physiology can be learned. The results are so incredible that we are all sure to hear more about this approach as experience grows.

So I tracked Dr. Fox down in his busy Jacksonville, Florida practice to fill us in on some details.

WD: Dr. Fox, could you tell us something about yourself and what led you to use carbohydrate restriction in your female patients?

MF: I have been in practice as a reproductive endocrinologist for 15 years. During that time, I have seen our specialty move from a broad based practice of reproductive endocrinology to a narrow IVF [in vitro fertilization] focus, with patients being pushed through IVF in a cookie-cutter fashion without any emphasis on non-medical therapy.

Our focus has been to remain as a broad practice where we individualize care and attempt in every case to achieve pregnancy short of IVF. Five years ago, this continued quest for better care led us into the insulin resistance, low-carbohydrate metabolic world that has transformed our practice, although our practice offers all aspects of reproductive endocrinology including sub-specialized minimally invasive surgery, and all available infertility options.

WD: I have been intrigued by your comments about improved fertility with the low-carb diet. Could you elaborate on this?

MF: Yes, five years ago, as more information regarding Polycystic Ovarian Disease or Syndrome (PCOD/S) and its relationship to insulin resistance (high insulin levels) was emerging, we had a simple realization. As we've known for some time, insulin stimulates excess male hormone levels in the ovary, which disrupts ovulation and fertility. Then our job was to lower or virtually eliminate high insulin levels. Again, in simple fashion, we looked at physiology and realized that insulin is released only in response to dietary carbohydrates. Thus, elimination of carbohydrates should resolve the problem. This, in fact, is the effect that we have seen.

In our previous approaches to PCOD, we utilized oral ovulation medicines generating pregnancy rates in the 40% range overall. Now, with the nutritional approach, for those patients that follow our recommendations, our pregnancy rates are over 90%! This has dramatically reduced the need for in vitro fertilization in these patients.

To extend this idea further, we first started with relative low-carbohydrate diets, such as the South Beach diet, but quickly realized this didn't produce a metabolic effect. Over time, it has borne out that only the very low-carbohydrate diet (VLCD) approach produces significant metabolic change. Our impression then was that the current U.S. nutritional exposure probably increases insulin levels and that this has a detrimental effect on fertility.

To counter this effect, we now recommend the VLCD to all fertility patients and their spouses. The pregnancy rates do seem much better overall, as well as seeing a reduction in miscarriage rates. For the first time at our national meeting last year, there were three articles that showed improved pregnancy rates in patients without PCOD or insulin resistance in IVF when Glucophage was used. This drug decreases insulin. This supports the idea that our entire population is subjected to fertility-reducing high-carbohydrate diet.

WD: Do you see any other changes in these patients on the diet?

MF: Yes. All metabolic parameters, as well as many common complaints, improve. Cholesterol and triglyceride levels improve, while "good" HDL cholesterol levels increase. Weight drops at a pace of 12 lbs per month very steadily and we have many many patients who have experienced 50lb wt loss. Blood pressure decreases steadily in these patients and we are often able to get them off of cholesterol and blood pressure medicines. Common symptoms such as anxiety, sleep disturbances, decreased energy, migraine headaches and depression all dramatically improve. Again we can often get patients off depression and migraine suppression medications. So this approach helps in a multitude of areas.

WD: I was also interested in hearing more about your experience with morning sickness and the effects of a low-carb diet. Could you tell us more about this? Also, any thoughts on why this happens?

MF: As we continued to expand our thoughts about VLCD and fertility/pregnancy, we began to extend the nutritional approach into pregnancy. We know that pregnancy hormones dramatically worsen insulin resistance that is responsible for the condition, gestational diabetes. If insulin resistance is worsened, then reactive hypoglycemia is worsened. One of the biggest symptoms of hypoglycemia is nausea. So, in response to this, we have counseled our patients on the diet in pregnancy and have found a dramatic reduction in nausea. We recommend snacking every two hours in pregnancy.

The other "traditional" issue in pregnancy are cravings. These also likely stem from hypoglycemia. I have had many husbands tell us later that their wives, in contrast to friends etc, were calm and not moody or anxious during their pregnancies. Hypoglycemia probably is a serious issue for the fetus as well and may be the "signal" that turns on the insulin-resistant gene. Many theorists feel this might be an activated gene during the pregnancy.

WD: Do you use any unique approaches to the low-carbohydrate approach, e.g., inclusion of dairy, meal frequency, "induction" strategies (i.e., induction to the diet, not of labor!), etc.?

MF: Yes. As I'm sure everyone who works in the VLCD world does, we also have some tricks to make this work better. My biggest push, although hard to get patients to agree, is to see a counselor along with our follow-up in order to deal with "addictive behaviors" and "stress eating" that so many of our patients relate to us. Good stress management and cognitive behavioral therapy go a long way in helping this become a permanent change.

We also really push frequent calorie intake or "snacking." I think again that hypoglycemia produces an inborn drive to "cure" or "fix" starvation and leads to dramatic overeating. We have a short list of snacks that we recommend. The concept of hunger is offered as a failure of the program. We aim to eliminate hunger, as it represents hypoglycemia. The analogy I use is, if you drove your car until you ran out of gas before you ever sought to find gas, your life would be miserable. So it is the same with your metabolic engine: If you let it run out, the measures your system takes to fix it are very detrimental to life and certainly to nutritional health.

Our other big push is fat. People can wrap themselves around protein and vegetables, but they totally miss the high-fat (animal fat) part of the conversation. We have to really push that aspect. In regards to dairy, we allow for non-processed cheeses and minimal milk. An alternative is to mix about 4 oz whole milk with 4 oz of heavy whipping and 4 oz of water to create a "milk" with less sugar. Similarly, shakes and smoothies can be made with heavy whipping cream with pure whey protein powder added to create a liquid meal for those who "don't have time" to cook.

WD: Thanks, Dr. Fox. We look forward to hearing more about your approach in future.

Allow me to wear my Track Your Plaque hat for this post.

Mr. Richard Rawle is CEO of Utah company, Tosh, Inc. Mr. Rawle has been an avid follower of the Track Your Plaque program and has introduced the program to company employees. Here's what he has to say about the experience:

“Our company has been utilizing the principles of TYP [Track Your Plaque] for over a year and has experienced great results that have positively impacted the lives of our employees and our health care costs.

Since we began our wellness program, we have presented the TYP diet and lifestyle guidelines to all of our employees and their families. Although the overwhelming majority of our employees do not have cardiovascular issues, the preventative nature of TYP is too important not to be utilized. The TYP principles along with our increased focus on healthy living have already changed our group’s blood chemistry. HDL levels in particular have increased significantly and resulted in a large percentage of our employees having HDL levels of 60 or higher. Vitamin D levels have substantially increased and LDL levels have significantly decreased in the majority of our employees. Subsequently, in the 12 months just ended, our health care costs are some 35% less than other groups of comparable size and age.

I believe the TYP program has been an integral part of the success of our company's vast improvement in employee health/wellness, resulting in significant health care cost reductions."

Track Your Plaque saves lives. Track Your Plaque also saves money . . . lots of it. Despite the upfront costs of some additional blood testing and a heart scan, the dramatic reduction in need for medications, reduced heart attack, diabetes, and many other chronic conditions add up to a huge cost savings, much as Tosh, Inc. employees have enjoyed.

The Federal government has been looking towards large hospital systems to lead the way in healthcare delivery, systems that employ their physicians and possess economies of scale. But I say the answer to reducing healthcare costs will NEVER be found in hospital systems. Healthcare cost savings will be realized by delivering truly effective health solutions directly to people themselves, much as we do in Track Your Plaque.

Many people ask: "How can wheat be bad if it's in the Bible?"

Wheat is indeed mentioned many times in the Bible, sometimes literally as bread, sometimes metaphorically for times of plenty or freedom from starvation. Moses declared the Promised Land "a land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey" (Deuteronomy 8:8).

Wheat is a fixture of religious ceremony: sacramental bread in the Eucharist of the Christian church, the host of the Holy Communion in the Catholic church, matzoh for Jewish Passover, barbari and sangak are often part of Muslim ritual. Wheat products have played such roles for millenia.

So how can wheat be bad?

What we call wheat today is quite different from the wheat of Biblical times. Emmer and einkorn wheat were the original grains harvested from wild growths, then cultivated. Triticum aestivum, the natural hybrid of emmer and goatgrass, also entered the picture, gradually replacing emmer and einkorn.

The 25,000+ wheat strains now populating the farmlands of the world are considerably different from the bread wheat of Egyptians, different in gluten content, different in gluten structure, different in dozens of other non-gluten proteins, different in carbohydrate content. Modern wheat has been hybridized, introgressed, and back-bred to increase yield, make a shorter stalk in order to hold up to greater seed yield, along with many other characteristics. Much of the genetic work to create modern wheat strains are well-intended to feed the world, as well as to provide patent-protected seeds for agribusiness.

What is not clear to me is whether original emmer, einkorn, and Triticum aestivum share the adverse health effects of modern wheat.

Make no mistake about it: Modern wheat underlies an incredible range of modern illnesses. But do these primitive wheats, especially the granddaddy of them all, einkorn, also share these effects or is it a safe alternative--if you can get it?

I've ordered 2 lb of einkorn grain, unground, from Massachusetts organic farmer, Eli Rogosa, who obtained einkorn seed from the Golan Heights in the Middle East. We will be hand-grinding the wheat and making einkorn bread. We will eat it and see what happens.

Wheat starches are composed of polymers (repeating chains) of the sugar, glucose. 75% of wheat carbohydrate is the chain of branching glucose units, amylopectin, and 25% is the linear chain of glucose units, amylose.

Both amylopectin and amylose are digested by the salivary and stomach enzyme, amylase, in the human gastrointestinal tract. Amylopectin is more efficiently digested to glucose, while amylose is less efficiently digested, some of it making its way to the colon undigested.

Amylopectin is therefore the “complex carbohydrate” in wheat that is most closely linked to its blood sugar-increasing effect. But not all amylopectin is created equal. The structure of amylopectin varies depending on its source, differing in its branching structure and thereby efficiency of amylase accessibility.

Legumes like kidney beans contain amylopectin C, the least digestible—hence the gas characteristic of beans, since undigested amylopectin fragments make their way to the colon, whereupon colonic bacteria feast on the undigested starches and generate gas, making the sugars unavailable for you to absorb.

Amylopectin B is the form found in bananas and potatoes and, while more digestible than bean amylopectin C, still resists digestion to some degree.

The most digestible is amylopectin A, the form found in wheat. Because it is the most readily digested by amylase, it is the form that most enthusiastically increases blood sugar. This explains why, gram for gram, wheat increases blood sugar to a much greater degree than, say, chickpeas.

The amylopectin A of wheat products, “complex” or no, might be regarded as a super-carbohydrate, a form of highly digestible carbohydrate that is more efficiently converted to blood sugar than nearly all other carbohydrate foods.

10,000 years ago, Neolithic humans did not obtain wheat products from the bagel shop, grocery store, or Krispy Kreme. They obtained wheat by locating a nearby wild-growing field of wild emmer or einkorn wheat grass, then harvesting it with their stone sickles.

Neolithic humans, such as the Natufians of the Fertile Crescent, carried their freshly-cut wheat home, then ground it by hand using homemade mortar and pestle. As yeast-raised bread was still some 5000 years in the future, emmer and einkorn wheat was not used to bake bread, but was consumed as a porridge in bowls. Einkorn has the simplest genetic code of 14 chromosomes, while emmer has 28 chromosomes.

A third variety of wheat appeared on the scene around 9000 years ago, a natural hybridization between emmer and goat grass, yielding the 42-chromosome Triticum aestivum species. Egyptians learned how to cause wheat to rise around 3000 BC, yielding bread, rather than the unleavened flatbreads of their predecessors.

From the original three basic varieties of wheat available to Neolithic man, over the past 30 years wheat has exploded to over 25,000 varieties. Where did the other 24,997+ strains come from?

In the 1980s, thousands of new wheat strains arose from hybridization experiments, many of them conducted in Mexico. Then, in the late 1980s, genetic engineering quietly got underway in which geneticists inserted or deleted single genes, mostly designed to generate specific characteristics, such as height, yield per acre, drought resistance, but especially resistance to various pesticides and weed killers. The fruits of these efforts were introduced into the market in 1994. Most of the genetically modified foods were thought to be only minor modifications of the unmodified original and thus no safety testing in animals or humans was conducted.

We now have many thousands of wheat strains that are different in important ways from original emmer, einkorn, and Triticum aestivum wheat. Interestingly, it has been suggested that einkorn wheat fails to provoke the same immune response characteristic of celiac disease provoked by modern wheat gluten, suggesting a different amino acid structure in gluten proteins. Another difference: Emmer wheat is up to 40% protein, compared to around 12% protein for modern wheat.

In other words, the wheat of earlier agricultural humans, including the wheat of Biblical times, is NOT the wheat of 2010. Modern wheat is quite a different thing with differing numbers of chromosomes, different genes due to human manipulation, varying gluten protein composition, perhaps other differences.

Somewhere in the shuffle and genetic sleight-of-hand that has occurred over the last 30 years, wheat changed. What might have been the "staff of life" has now become the cause of an incredible array of diseases of "wheat" intolerance.

This is a true story that I personally witnessed.

A 60-some year old man heard that nattokinase "thinned the blood." So he had been taking it for the past 6 months.

One week before he came to see me, he abruptly became quite breathless. He was unable to walk more than 20 feet or bend over to tie his shoes due to the breathlessness.

He came to see me in the office. I was alarmed by how breathless he was without signs of heart failure or other obvious explanation. I sent him for an immediate CT pulmonary angiogram. Within 30 minutes, we had the diagnosis: a large "saddle" pulmonary embolus, meaning a large blood clot that straddled the right and left main pulmonary arteries. One wrong move and . . . bang! He would have been dead within a couple of minutes, since a large clot can completely occlude the large arteries feeding the lung, essentially corking any blood circuiting through the lungs and back to the left side of the heart. (Causing, incidentally, electromechanical dissociation, in which the heart keeps beating for a few minutes but no blood is being pumped. CPR can keep you alive for a few minutes, then it's over.)

When I advised the patient of the diagnosis (after initiating the REAL anticoagulants), he said, "But I was taking nattokinase!"

Exactly. Blood clots are no laughing matter. They are potentially fatal events. Betting your life on some company's advertisement is nothing short of foolish.

Anyone who reads The Heart Scan Blog knows that I am an avid supporter of nutritional supplements. I even write articles and consult for the supplement industry. But I truly despise hearing unfounded marketing claims that some supplement companies will make in the pursuit of a fast buck.

There is no doubt that we need better, safer methods to deal with dangerous blood clots, whether in the lung, pelvis, or other areas. But, before anyone takes a leap based on the extravagant marketing claims made by a supplement manufacturer, you want to be damn sure there are real data--not marketing claims, REAL data--before you use something like nattokinase in place of a proven therapy.

Don't confuse the very interesting, though unpalatable, natto with nattokinase. Natto contains vitamin K2 and some other interesting compounds, including nattokinase.

Wheat is among the most destructive components of the human diet, a food that is responsible for inflammatory disease, diabetes, heart disease, several forms of intestinal diseases, schizophrenia, bipolar illness, ADHD, behavioral outbursts in autistic children . . . just to name a few.

But why?

Wheat is mostly carbohydrate. That explains its capacity to cause blood sugar to increase after eating, say, a turkey sandwich on whole wheat bread. The rapid release of sugars likely underlies its capacity to create visceral fat, what I call "wheat belly."

But neither the carbohydrate nor the other components, like bran and B vitamins, can explain all the other adverse health phenomena of wheat. So what is it in wheat that, for instance, worsens auditory hallucinations in paranoid schizophrenics? Is it the gluten?

First of all, what is gluten?

Gluten protein is the focus of most wheat research conducted by food manufacturers and food scientists, since it is the component of wheat that confers the unique properties of dough, allowing a pizza maker to roll and toss pizza crust in the air and mold it into shape. The distinctive “doughy” quality of the simple mix of wheat flour and water, unlike cornstarch or rice starch, for instance, properties that food scientists call “viscoelasticity” and “cohesiveness,” are due to the gluten. Wheat is mostly carbohydrate, but the 10-15% protein content is approximately 80% gluten. Wheat without gluten would lose its unique qualities that make it desirable to bakers and pizza makers. Gluten is also the component of wheat most confidently linked to immune diseases like celiac.

The structure of gluten proteins has proven frustratingly elusive to characterize, as it changes over time and varies from strain to strain. But an understanding of gluten structure may be part, perhaps most, of the answer to the question of why wheat provokes negative effects in humans.

The term “gluten” encompasses two primary families of proteins, the gliadins and the glutenens. The gliadins, one of the protein groups that trigger the immune response in celiac disease, has three subtypes: a/ß-gliadins, ?-gliadins, and ?-gliadins. The glutenins are repeating structures, or polymers, of more basic protein structures.

Beyond gluten, the other 20% or so of non-gluten proteins in wheat include albumins, prolamins, and globulins, each of which can also vary from strain to strain. In total, there are over 1000 other proteins that serve functions from protection of the grain from pathogens, to water resistance, to reproductive functions. There are agglutinins, peroxidases, a-amylases, serpins, and acyl CoA oxidases, not to mention five forms of glycerinaldehyde-3-phosphate dehydrogenases. I shouldn’t neglect to mention the globulins, ß-purothionin, puroindolines a and b, tritin, and starch synthases.

As if this protein/enzyme smorgasbord weren’t enough, food processors have also turned to fungal enzymes, such as cellulases, glucoamylases, xylanases, and ß-xylosidases to enhance leavening and texture. Many bakers also add soy flour to enhance mixing and whiteness, which introduces yet another collection of proteins and enzymes.

In short, wheat is not just a simple gluten protein with some starch and bran. It is a complex collection of biological material that varies according to its genetic code.

While wheat is primarily carbohydrate, it is also a mix of gluten protein which can vary in structure from strain to strain, as well as a highly variable mix of non-gluten proteins. Wheat has evolved naturally to only a modest degree, but it has changed dramatically under the influence of agricultural scientists. With human intervention, wheat strains are bred and genetically manipulated to obtain desirable characteristics, such as height (ranging from 18 inches to over 4 feet tall), “clinginess” of the seeds, yield per acre, and baking or viscoelastic properties of the dough. Various chemicals are also administered to fight off potential pathogens, such as fungi, and to activate the expression of protective enzymes within the wheat itself to “inoculate” itself against invading organisms.

From the original two strains of wheat consumed by Neolithic humans in the Fertile Crescent 9000 years ago (Emmer and Einkorn), we now have over 200,000 strains of wheat virtually all of which are the product of genetic manipulations that have modified the protein structure of wheat. The extraordinary complexity of wheat proteins have therefore created a huge black box of uncertainty in pinpointing which protein causes what.

But there's an easy cure for the uncertainty: Don't eat it.

The concept of glycemic index is meant to help determine what foods raise blood sugar a lot vs. what foods raise blood sugar a little. Dr. Jennie Brand-Miller's searchable database can be found here.

I have to admit that glycemic index provided me with a sense of false assurance for some years. It screwed up my health until I came to understand the issues a lot better.

For those of you just starting out in nutritional conversations, glycemic index (GI) represents a comparison of the blood glucose area-under-the-curve (AUC) over 2 hours after consuming 50 grams of the food in question compared to the AUC of glucose or white bread. Volunteers involved in developing these values are healthy people who are generally of normal weight.

Glucose, by definition, has a GI of 100. An equal quantity of sucrose (50% glucose, 50% fructose) has a GI of 60, lower than glucose. An equal quantity of whole wheat bread has a GI of 68-77 (Yes: The GI of whole wheat is higher than sucrose). Non-carbohydrate foods, such as eggs or avocado, have no GI since they do not impact on blood glucose.

Because the GI is also sensitive to how much carbohydrate is contained, the concept of Glycemic Load (GL) was introduced:

GL = (GI x amount of carbohydrate) / 100

GL is therefore the GI that incorporates the glycemic potential of the food of interest. GI does not vary with portion size; GL varies with portion size.

Let's take whole wheat pasta, a food regarded by most people as a healthy choice. Whole wheat pasta has a GI of 55--fairly low--and a GL of 29. A serving of 180 g (approximately 6 oz cooked) provides 50 g carbohydrates.

People who advocate that low-glycemic index foods would say that this is a desirable profile and should therefore replace high-glycemic index foods.

I say WRONG. First of all, most of us are not slender 20-somethings. We will therefore not show the same response as a young, slender person (like the GI volunteers), but will show exagerrated blood sugar responses. So this much low-glyemic index whole wheat pasta will typically yield a blood sugar of 120-200 mg/dl in non-diabetic people, high enough to trigger glycation. Sure, a high-glycemic index food, such as white flour birthday cake with plenty of sugary icing, might trigger a blood sugar of 140-250 mg/dl, much worse. But that doesn't make the lower blood sugar following pasta any less bad--it's still terrible.

Another issue: GI is assessed over a 2-hour timeline. What if blood sugar remains high in a sustained way, say, over 6 hours? That's precisely what whole wheat pasta will do: Keep blood sugar high for an extended period.

So not only does a low-glycemic index food like pasta increase blood sugar in most of us extravagantly, it does so in a sustained way.

Lastly, low-glycemic index pasta still triggers small LDL particles to an extreme degree, as I discussed in the previous Heart Scan Blog post, Small LDL: Complex vs. simple carbohydrates.

Don't be false reassured by the notion of low GI or GL. In fact, I'd go so far as to say that NO glycemic index is a GOOD glycemic index (or load). The foods we want to dominate our diet are the foods that aren't even listed in the GI database.
