Wheat brain

30. mars 2011 William Davis (52)
Among the most common effects of wheat are those on the brain.

Consume wheat and susceptible individuals will experience a subtle euphoria. Others experience mental cloudiness or sleepiness. (This is what I personally get.)

It gets worse. Children with ADHD and autism have difficulty concentrating on a task and have behavioral outbursts after a cookie. Schizophrenics experience paranoid delusions, auditory hallucinations, and worsening of social detachment. People with bipolar disorder can have the manic phase triggered by a breadcrumb. All these effects are blocked by administering drugs that block the brain's opiate receptors. (This is why, by the way, a drug company is planning to release an oral agent, naltrexone, formerly administered to heroin addicts to help control addiction, for weight loss: block the euphoric effect, take away the temptation, lose weight.)

Here is Heart Scan Blog reader, Nicole's, mental fog story:

I have been grain-free (no gluten free grains either) for quite a long time (about a year and a half). Earlier this week, I decided to try white bread and pasta. The experiment only lasted two days. I had horrible terminal insomnia both nights, causing me on the second night to wake up at 2:30 am unable to get back to sleep at all. I felt drugged and in a mind-fog all the next day and even dozed off a few times! Luckily I had the day off work.

I had very bad forgetfulness also. I forgot that I left my bag and groceries at work, so I had to go back for them. Then I had to use my husband's keys to get in because I thought my keys were in my bag, but it turns out they were in my pocket. Then I got my bag, set the alarm, locked the door and then realized I forgot my groceries. So I had to re-open the door, unset the alarm, and go back for the groceries. Then I locked the door, forgetting to set the alarm, so I had to unlock it, open up and set the alarm. It was just ridiculous, I am NEVER like that!

In addition to the insomnia and forgetfulness, I also had horrible anxiety and paranoia, almost to the point of panic. Which I NEVER have, I am usually very easy-going, even-tempered, and worry-free. But this was horrible, I really was quite paranoid and anxious about everything. Weird!

And the worst, was that in just two days of eating wheat, I gained 4 lbs and 2% bodyfat!! It's two days wheat-free now, and it's finally going back down, but wow. Just two days of wheat-eating caused that much weight and fat gain!

Anyway, I've learned my lesson and will continue to avoid grains (including gluten free grains) entirely.

Eat more "healthy whole grains"? Modern dwarf Triticum aestivum, perverted even further by agricultural geneticists and modern agribusiness, subsidized by the U.S. government to permit $5 pizza, is better than any terrorist plot to discombobulate the health and performance of the American people.

The Westman Diet

27. mars 2011 William Davis (71)
Dr. Eric Westman has been a vocal proponent of carbohydrate restriction to gain control over diabetes, as have Drs. Richard Bernstein, Mary Vernon, Richard Feinman, and Jeff Volek.

Several studies over the years have demonstrated that reductions in carbohydrate content of the diet yield reductions in weight and HbA1c (glycated hemoglobin, a reflection of average blood glucose over the preceding 60-90 days).

Among the more important recent clinical studies is a small experience from Duke University's Dr. Eric Westman. In this study, obese type 2 diabetics reduced carbohydrate intake to 20 grams per day or less: no wheat, oats, cornstarch, or sugars. Participants ate nuts, cheese, meats, eggs, and non-starchy vegetables.

After 6 months, average weight loss was 24.4 lbs, BMI was reduced from 37.8 to 34.4. At the end of the study, 95% of participants on this severe carbohydrate restriction reduced or eliminated their diabetes medications.

That was only after 6 months. Note that the ending BMI was still quite well into the obese range. Imagine what another 6-12 months would do, or achieving BMI somewhere closer to ideal.

Curiously, this idea of severe low-carbohydrate restriction to cure or minimize diabetes is not new. Sir William Osler, one of the founders of Johns Hopkins Hospital and author of the longstanding authoritative text, Principles and Practice of Medicine, advocated an diet identical to Dr. Westman's diet. So did Dr. Frederick Banting, discoverer of the pancreatic extract, insulin, to treat childhood diabetics. Before insulin, Banting and his colleagues at the University of Toronto used carbohydrate elimination (less than 10 g per day) to prolong the lives of children with diabetes.

This lesson was also learned many times during war time, when staples like bread were unavailable. The Siege of Paris in 1870 yielded cures for diabetes in many (or at least they stopped passing urine that tasted--yes, tasted--sweet and attracted flies), only to have it recur after the siege was over.

These are lessons we will have to relearn. As long as the American Diabetes Association and most physicians continue to advocate a diet of reduced fat, increased carbohydrate that includes plenty of "healthy whole grains," diabetics will continue to be diabetics, taking their insulin and multiple medications while developing neuropathy (nervous system degeneration), nephropathy (kidney disease and failure), atherosclerosis and heart attack, cataracts, and die 8 to 10 years earlier than non-diabetics.

All the while, we've had the combined wisdom from antiquity onwards: Carbohydrates cause diabetes; elimination of carbohydrates cures diabetes.

(This applies, of course, only to adult overweight type 2 diabetics, not type 1 or some of the other variants.)

Handy dandy carb index

25. mars 2011 William Davis (21)
There are a number of ways to gauge your dietary carbohydrate exposure and its physiologic consequences.

One of my favorite ways is to do fingerstick blood sugars for a one-hour postprandial glucose. I like this because it provides real-time feedback on the glucose consequences of your last meal. This can pinpoint problem areas in your diet.

Another way is to measure small LDL particles. Because small LDL particles are created through a cascade that begins with carbohydrate consumption, measuring them provides an index of both carbohydrate exposure and sensitivity. Drawback: Getting access to the test.

For many people, the most practical and widely available gauge of carbohydrate intake and sensitivity is your hemoglobin A1c, or HbA1c.

HbA1c reflects the previous 60 to 90 days blood sugar fluctuations, since hemoglobin is irreversibly glycated by blood glucose. (Glycation is also the phenomenon responsible for formation of cataracts from glycation of lens proteins, kidney disease, arthritis from glycation of cartilage proteins, atherosclerosis from LDL glycation and components of the arterial wall, and many other conditions.)

HbA1c of a primitive hunter-gatherer foraging for leaves, roots, berries, and hunting for elk, ibex, wild boar, reptiles, and fish: 4.5% or less.

HbA1c of an average American: 5.2% (In the population I see, however, it is typically 5.6%, with many 6.0% and higher.)

HbA1c of diabetics: 6.5% or greater.

Don't be falsely reassured by not having a HbA1c that meets "official" criteria for diabetes. A HbA1c of 5.8%, for example, means that many of the complications suffered by diabetics--kidney disease, heightened risk for atherosclerosis, osteoarthritis, cataracts--are experienced at nearly the same rate as diabetics.

With our wheat-free, cornstarch-free, sugar-free diet, we have been aiming to reduce HbA1c to 4.8% or less, much as if you spent your days tracking wild boar.

Battery acid and oatmeal

23. mars 2011 William Davis (38)
Ever notice the warnings on your car's battery? "Danger: Sulfuric acid. Protective eyewear advised. Serious injury possible."

Sulfuric acid is among the most powerful and potentially harmful acids known. Get even a dilute quantity in your eyes and you will suffer serious burns and possibly loss of eyesight. Ingest it and you can sustain fatal injury to the mouth and esophagus. Sulfuric acid's potent tendency to react with other compounds is one of the reasons that it is used in industrial processes like petroleum refining. Sulfuric acid is also a component of the harsh atmosphere of Venus.

Know what food is the most potent source of sulfuric acid in the body? Oats.

Yes: Oatmeal, oat bran, and foods made from oats (you know what breakfast cereal I'm talking about) are the most potent sources of sulfuric acid in the human diet.

Why is this important? In the transition made by humans from net-alkaline hunter-gatherer diet to net-acid modern overloaded-with-grains diet, oats tip the scales heavily towards a drop in pH, i.e., more acidic.

The more acidic your diet, the more likely it is you develop osteoporosis and other bone diseases, oxalate kidney stones, and possibly other diseases.

Here's one reference for this effect.

What'll it be: Olive oil or bread?

21. mars 2011 William Davis (0)
We frequently discuss the advisability of consuming fats, carbohydrates, and various types within each category.

But what's the worst of all? Combining fats with carbohydrates.

Putting aside the wheat-is-worst form of carbohydrate issue and treating bread as a prototypical carbohydrate, let's play out a typical scenario, a make-believe feeding study in which a theoretical person is fed specific foods.

John is our test person, a 40-year old, 5 ft 10 inch, 210 lb, BMI 27.7 (roughly the mean for the U.S.) He starts with an average American diet of approximately 55% carbohydrates and 30% fat. Starting lipoproteins (NMR):

LDL particle number 1800 nmol/L
Small LDL 923 nmol/L


(The LDL particle number of 1800 nmol/L translates to measured LDL cholesterol of 180 mg/dl, i.e., drop last digit or divide by 10.)

Also, calculated LDL cholesterol is 167 mg/dl (yes, underestimating "true" measured LDL), HDL 42 mg/dl, triglycerides 170 mg/dl.

We feed him a diet increased in carbohydrates and reduced in fat, especially saturated fat, with more breakfast cereals, breads and other wheat products, pasta, fruit juices and fruit, and potatoes. After four weeks:

LDL particle number 2200 nmol/L
Small LDL 1378 nmol/L

Note that LDL particle number has increased by 400 nmol/L due entirely to the increase in small LDL particles triggered by carbohydrate consumption. Lipids show calculated LDL cholesterol 159 mg/dl--yes, a decrease, HDL 40 mg/dl, triglycerides 189 mg/dl. (At this point, if John's primary care doctor saw these numbers, he would congratulate John on reducing his LDL cholesterol and/or suggest a fibrate drug to reduce triglycerides.)

John takes a rest for four weeks during which his lipoproteins revert back to their starting values. We then repeat the process, this time replacing most carbohydrate calories with fats, weighed heavily in favor of saturated fats like fatty red meats, butter and other full-fat dairy products. After four weeks:

LDL particle number 2400 nmol/L


Let's

Chocolate peanut butter cup smoothie

19. mars 2011 William Davis (18)
Here's a simple recipe for chocolate peanut butter cup smoothie.

The coconut milk, nut butter, and flaxseed make this smoothie exceptionally filling. If you are a fan of cocoa flavonoids for reducing blood pressure, then this provides a wallop. Approximately 10% of cocoa by weight consists of the various cocoa flavonoids, like procyanidins (polymers of catechin and epicatechin) and quercetin, the components like responsible for many of the health benefits of cocoa.


Ingredients:
1/2 cup coconut milk
1 cup unsweetened almond milk
2 tablespoons cocoa powder (without alkali)
2 tablespoons shredded coconut (unsweetened)
1 tablespoon ground flaxseed
1 teaspoon almond extract
1 1/2 tablespoons natural peanut, almond, or sunflower seed butter
Non-nutritive sweetener to taste (stevia, Truvia, sucralose, xylitol, erythritol)
4 ice cubes

Combine ingredients in blender. Blend and serve.

If you plan to set any of the smoothie aside, then leave out the flaxseed, as it absorbs water and will expand and solidify if left to stand.

For an easy variation, try adding vanilla extract or 1/4 cup of sugar-free (sucralose) vanilla or coconut syrup from Torani or DaVinci and leave out the added sweetener.

The compromise I draw here is the use of non-nutritive sweeteners. Beware that they can increase appetite, since they likely trigger insulin release. However, this smoothie is so filling that I don't believe you will experience this effect with this recipe.

Letter from the insurance company

18. mars 2011 William Davis (24)
Claudia got this letter from her health insurance company:

Dear Ms. ------,

Based on a recent review of your cholesterol panel of January 12, 2011, we feel that you should strongly consider speaking to your doctor about cholesterol treatment.

Reducing cholesterol values to healthy levels has been shown to reduce heart attack risk . . .

Okay. So the health insurer wants Claudia to take a cholesterol drug in the hopes that it will reduce their exposure to the costs for her future heart catheterization, angioplasty and stent, or bypass surgery. This is understandable, given the extraordinary costs of such hospital services, typically running from $40,000 for a several hour-long outpatient catheterization procedure, to as much as $200,000 for a several day long stay for coronary bypass surgery.

So what's the problem?

Here are Claudia's most recent lipid values:

LDL cholesterol 196 mg/dl
HDL 88 mg/dl
Triglycerides 37 mg/dl
Total cholesterol 291 mg/dl

By the criteria followed by her health insurer, both total and LDL cholesterol are much too high. Note, of course, that LDL cholesterol was a calculated value, not measured.

Here are Claudia's lipoproteins, drawn simultaneously with her lipids:

LDL particle number 898 nmol/L
Small LDL particle number less than 90 nmol/L (Values less than 90 are not reported by Liposcience)

LDL particle number is, by far and away, the best measure of LDL particles, an actual count of particles, rather than a guesstimate of LDL particles gauged by measuring cholesterol in the low-density fraction of lipoproteins (i.e., LDL cholesterol). It is also measured and is highly reproducible.

To convert LDL particle number in nmol/L to an LDL cholesterol-like value in mg/dl, divide by ten (or just drop the last digit).

Claudia's measured LDL is therefore 89 mg/dl--54% lower than the crude calculated LDL suggests.

This is because virtually all of Claudia's LDL particles are large, with little or no small. This situation throws off the crude assumptions built into the LDL calculation, making it appear that she has very high LDL cholesterol.

Do you think that Big Pharma advertises this phenomenon?

Healthy smoothies

15. mars 2011 William Davis (51)
I've now seen several people who have either caused themselves to be diabetic or to have other phenomena associated with excessive consumption of carbohydrates, all by innocently indulging in a carbohydrate-packed smoothie every morning.

Kay, for instance, has a smoothie of a half-pint blueberries, a banana, a scoop of whey, low-fat yogurt, a cup of milk every morning. The rest of her diet was fairly healthy: salads with oil-based dressing for lunch, salmon and asparagus for dinner, only an occasional carbohydrate indulgence outside of her morning smoothie ritual. Yet she had a HbA1c (a reflection of prior 60 to 90 days average blood sugar) at the near-diabetic range of 5.9%.

The mistake most people make when making smoothies is relying too heavily on carbohydrates like fruit. A smoothie like the one made by Kay can easily top 50, 60, or 70 grams carbohydrates per serving, more than sufficient to send blood sugars up to 150 mg/dl or more.

So what can you put in your smoothie and not send you over the edge to diabetes, small LDL, and all the other undesirable phenomena of excessive carbohydrates? Here's a list:

--coconut milk, unsweetened almond milk. Less desirable: milk, full-fat soymilk
--ground flaxseed
--oils: flaxseed oil, coconut oil (melted), extra-light olive oil, walnut oil
--dried coconut
--extracts: vanilla, almond, coconut, cherry, hazelnut
--spices: cinnamon, nutmeg, ginger
--herbs: mint leaves, cilantro
--cocoa powder (unsweetened)
--nut or seed butters (peanut butter, almond butter, sunflower seed butter)
--tofu
--exotic ingredients (ingredients you wouldn't expect in a smoothie): spinach, kale, cucumber

How do you sweeten a smoothie? This is what trips up most people. If you resort to fruit like bananas, pineapple, or apple, you will readily send your blood sugar skyward. Honey, agave syrup, and sugar, of course, all increase blood sugar and/or have the adverse effects of fructose. Be careful of yogurt, also, for similar reasons.

Therefore, to sweeten your smoothie, consider:

--Small servings of berries, e.g., 8-10 blueberries, 2 strawberries, a few wedges of apple, half a kiwi
--Non-nutritive sweeteners like stevia, Truvia, sucralose, xylitol, erythritol. Also, sugar-free (sucralose-based) syrups like those from DaVinci and Torani are useful. (Just be aware that non-nutritive sweeteners can increase appetite--use sparingly.)

Also, note that, if you have divorced yourself from wheat, cornstarch, and sugars, your desire for sweet should be much reduced. Foods other people find just right will taste sickeningly sweet to you. You might therefore find that foods like peanut butter or coconut milk have a mild natural sweetness; added sweetness is only minimally necessary.

Coming next: I'll share a smoothie recipe or two of mine. Anyone want to share a recipe?

Insulin secretagogue

14. mars 2011 William Davis (34)
Dairy products have the peculiar property of triggering pancreatic release of insulin. The research group at Lund University in Sweden have contributed the most to documenting this phenomenon:




Mean (±SEM) incremental changes (?) in serum insulin in response to equal amounts of carbohydrate from a white-wheat-bread reference meal (x) and test meals of whey (?), milk (?), cheese (?), cod (?), gluten-low (?), and gluten-high (?) meals. From Nilsson 2004.

Note that it is the area under the curve (AUC), not the peak value, that assumes greatest importance.

Dairy products, especially milk, whey, and yogurt, are insulin secretagogues: they stimulate pancreatic release of insulin. The effect is likely due to amino acids and/or polypeptides in dairy products. (The effect is less prominent with cheese. Also see this study.)

By conventional wisdom, this may be a good thing, since the excess insulin will blunt the glucose rise after consumption. However, in my book, this is not such a good thing, since most of us have tired, beaten, overworked pancreatic beta cells from our decades of carbohydrate overconsumption. I fear that the effect of dairy products just take us a bit closer to beta cell failure: diabetes.

Good news: The effect is least with cheese.

Be gluten-free without "gluten-free"

9. mars 2011 William Davis (23)
While I've discussed this before, it is such a confusing issue that I'd like to discuss it again.

I advocate wheat elimination because consumption of products made from modern dwarf Triticum aestivum:

--Triggers formation of extravagant quantities of small LDL and LDL particle number (or apoprotein B)
--Triggers inflammatory phenomena like c-reactive protein, increases leptin resistance, and reduction of the protective adipocytokine, adiponectin.
--Encourages accumulation of deep visceral fat ("wheat belly") that is inflammatory and causes resistance to insulin
--Increases blood sugar more than nearly all other foods--higher than a Milky Way bar, higher than a Snickers bar, higher than table sugar.
--Is being linked to a growing number of immune-mediated diseases, including celiac disease (quadrupled over past 50 years), type 1 diabetes in children, and cerebellar ataxia and peripheral neuropathies.

This last group of wheat-related phenomena are primarily due to gluten, the collection of 50+ proteins found in each wheat plant. For this reason, people diagnosed with celiac disease are advised to eliminate gluten from wheat and other sources (barley, rye, triticale, bulgur) and to eat gluten-free foods.

Gluten-free has therefore come to be viewed as wheat-free and problem-free. It ain't so.

Among the few foods that increase blood glucose higher than wheat: cornstarch, rice starch, potato starch, and tapioca starch--Yup: the ingredients commonly used to replace wheat in gluten-free foods. They are also flagrant triggers of the small LDL pattern, along with increased triglycerides, reduced HDL, increased visceral fat, increased blood pressure. In short, gluten-free foods lack the immune and brain effects of wheat gluten, but still make you fat, hypertensive, and diabetic.

I tell patients to view gluten-free foods like jelly beans: Gluten-free pancakes, muffins, breads, etc. are indulgences, not healthy replacements for wheat. It's okay to have a few jelly beans now and then. But they should not be part of a frequent or daily routine. Same with gluten-free foods.

What role cholesterol medication?

10. April 2006 William Davis (0)
A frequent conversation point among my patients, as well as participants in the www.cureality.com program, is "Are cholesterol medications really necessary?"

No, they are not. What IS necessary is to correct all manifest and hidden causes of coronary plaque. Among these causes, in my view, is LDL cholesterol of 60 mg/dl or greater. There are many other causes of coronary plaque--e.g., small LDL particles, unrecognized hypertension, Lp(a), hidden diabetic patterns, etc.--but reducing LDL to 60 mg is still an important part of a plaque-reversing effort.

Insofar as we wish to get LDL to this goal, the statin cholesterol drugs like Lipitor, Zocor, Crestor, etc. may play a role. However, they should only be considered after a full effort dietary program is pursued. Don't follow the American Heart Association's diet unless you want to fail. It's nonsense.

For a more detailed discussion of how to use nutrition and nutritional supplements to reduce LDL cholesterol, go to www.lef.org, the website for the Life Extension Foundation. I wrote an article for their magazine called "Cholesterol and Statin Drugs: Separating Hype from Reality". You'll find the article at http://search.lef.org/cgi-src-bin/MsmGo.exe?grab_id=0&page_id=1295&query=davis%20cholesterol%20natural&hiword=CHOLESTEROLA%20CHOLESTEROLS%20DAVI%20DAVID%20DAVIE%20DAVIES%20DAVIN%20DAVIO%20DAVISON%20DAVISS%20DAVIT%20NATURALBASED%20NATURALES%20NATURALIZED%20NATURALLY%20NATURALS%20NATURE%20NATURES%20cholesterol%20davis%20natural%20.)

Can your plaque-reversal efforts succeed without statin drugs? It depends on your causes. For instance, someone with small LDL and Lp(a) only may do great on our basic program and then add niacin. Unfortunately, another person with a starting LDL cholesterol of 240 mg/dl--sky high--will have more success with these drugs.

Believe me, I am no blind supporter of drug companies and their flagrantly profit-seeking practices which, in my view, are cut-throat, shoving anyone and anything out of their way to increase profits and market share. I share many of Dr. Dave Warnarowski's views on how vicious their tactics can be; see his recent Blog post at http://www.drdavesbest.com/blog/ called "I smell a rat".

Nonetheless, the deep and well-funded research of the pharmaceutical industry does yield some useful tools. You don't have to love the insect exterminator, but if your house is being eaten by termites, his services can be useful. Same thing with these drugs. Useful--not the complete answer, not even close, but nonetheless useful in the right situations. Sometimes antibiotics are necessary, even life saving. That's how cholesterol drugs are, too.

Take it all in the proper perspective. Your goal is not cholesterol reduction, per se, but plaque control, preferably reversal.

Supplement Mania!

9. April 2006 William Davis (3)
Ever hear of "polypharmacy"? That's when someone takes too many medicines. People will have lists of 15-20 prescription medicines, for instance, with crazy interactions and oodles of side-effects.

Well, how about "poly-supplments"? That's when someone takes a large number of nutritional supplements.

Let me tell you about a 45 year old man I met.

In an effort to rid himself of risk for heart disease that he felt was likely shared with his family (brother and father diagnosed with heart attacks in their late 40s), Steve followed a program of nutritional supplementation. You name it, he took it: hawthorne, anti-oxidant mixtures, vitamins C, E, B-complex, saw palmetto, 7-keto DHEA, velvet deer antler, gingko biloba, policosanol, chronium picolinate, green tea, pine bark extract, St. John's Wort, CoEnzyme Q10, papain and other digestive enzymes...He became a distributor for a nutritional supplement company to allow him to afford his own extraordinary program.

To satisfy himself that he had indeed "cured" himself of heart disease, he got himself a CT heart scan. His score: 470, in th 99th percentile. Steve's heart attack risk based on this score was around 10% per year. High risk, no question.

For weeks after his scan, Steve admitted walking around in a daze, not knowing what to do. Years of telling himself that he had effectively dealt with his heart disease risk, now all down the drain.

When we met, I persuaded him that to think that this collection of supplements would reverse heart disease was magical thinking. We trimmed his list down to the essentials and got him on the right track.

Heart disease is controllable and reversible, but not this way. Don't fool yourself into thinking that some collection of supplements will be enough to stamp out your heart disease risk. Just like taking an antibiotic when you don't have an infection achieves nothing, so does taking the wrong supplements.

What does heart scanning mean to you?

8. April 2006 William Davis (0)
CT heart scans can mean different things to different people.


What does a heart scan mean to you? There are several possibilities:

1) A way of reducing uncertainty in your future.

2) A tool to crystallize your commitment to health.

3) A device to help you track how successful your heart disease prevention program is.

4) A trick to get you in the hospital.

5) A moneymaking tool for unscrupulous physicians hoping to profit from "downstream" testing, particularly heart catheterizations.


Like anything, heart scans can be used for both good and evil. How can you be sure that your heart scan is put to proper use--for your benefit and not someone else's profit?

Simple: Get educated. Understand the issues, be armed with informed questions.

If, for instance, you're a 55-year old female with a heart scan score of 90, active without symptoms, and you're told to have a heart catheterization right off the bat---run the other way. This is bad advice. A heart procedure like catheterization at this score in an asymptomatic woman is very rarely necessary. That decision can only be made after a step-by-step series of decisions are made by a truly interested, unbiased party. (A stress test is almost always required in this situation before the decision can be made to proceed with a catheterization.)

Unfortunately, in 2006, getting unbiased advice from your doctor is still a struggle. That's why we started Track Your Plaque---unbiased information, uncolored by drug or device company support, with an interest in the truth.

Coronary disease is drying up!

7. April 2006 William Davis (1)
I had an interesting conversation with a device representative this morning. He was a sales representative for a major medical manufacturer of stents, defibrillators, and other such devices for heart disease.

Since I'm still involved with hospital heart care and cardiac catheterization laboratories, this representative asked me if I was interested in getting involved with some of the new cardiac devices making it to market over the next year or two. "The coronary market is drying up, what with coated stents and such. We've got to find new profit sources."

Well, doesn't that sum it up? If you haven't already had this epiphany, here it is:

HEART DISEASE IS A PROFITABLE BUSINESS!

Why else can hospitals afford billboards, $10 million dollar annual ad campaigns, etc.? They do it for PROFIT. Likewise, device and drug manufacturers see the tremendous profit in heart disease.

The representative's comments about the market "drying up" simply means that the use of coated stents has cut back on the need for repeat procedures. It does NOT mean that coronary disease is on the way out. On the contrary, for the people and institutions who stand to profit from heart care, there's lots of opportunity.

Track Your Plaque is trying to battle this trend. Heart disease should NOT be profitable. For the vast majority of us, it is a preventable process, much like house fires and dental cavities.

Mammogram for your heart

6. April 2006 William Davis (0)
With the booming popularity of "64-slice CT scans", there's a lot of mis-information about what these tests provide.

These tests are essentially heart scans with added x-ray dye injected to see the insides of the arteries. However, to accomplish this, a large quantity of radiation is required. In addition, the test is not quantitative, that is, it is not a precise measure that can be repeated year after year.

It is okay to have a 64-slice CT coronary angiogram. It is NOT okay to have one every year. That's too much radiation. However, a heart scan can be repeated every year, if necessary, to track progression or regression. Once stabilization (zero change) or reduction is achieved, then you're done (unless your life takes a major change, like a 20 lb weight gain).

The tried-and-true CT heart scan is the gold standard--easy, inexpensive, precise, and repeatable. Not true for 64-slice angiograms.

Is your doctor using "leeches"?

4. April 2006 William Davis (0)
What if you went to your doctor for a problem and he/she promptly placed leeches on your body?

Yeccchhhh! Would you go back? I'd bet that you'd run the other way as fast as your bleeding legs could take you. Outdated health practices like "bleeding" are outdated for good reason.

Then why would you allow your doctor to approach your heart disease prevention program by checking cholesterol and then waiting for symptoms to appear? That miserable approach leads to tragedy and death all too often--ask Bill Clinton! He might as well have had leeches!

Don't allow your doctor's ignorance or disinterest impede your prevention program. Get your coronary plaque measured, then attack it from all sides by knowing all causes, hidden and obvious. That's why Track Your Plaque is such an effective program.

I often wonder why more doctors aren't using this unbelievably powerful approach to deal with heart disease. But when I see colleagues implanting stents, defibrillators, and the like for many thousands of dollars per patient, the answers are obvious. Given a choice of a rational, effective program of prevention that pays the doctor a few hundred dollars for his time, versus $2000 to $10,000 for a procedure, you can see that the temptation is irresistible for many physicians.

All in the family--What to do if there's heart disease in your family

3. April 2006 William Davis (0)
What should you do if a close relative of yours is diagnosed with coronary disease?
This question came up recently with a patient of mine. The patient--a strapping, 47 year old businessman who looked the absolute picture of health--was undergoing bypass surgery. Although I'd met him for the purposes of plaque reversal, he was already having symptoms and his stress test was flagrantly abnormal, all discovered after a heart scan score of 765. On the day after the patient's bypass, the patient's brother came to me. Understandably concerned about his own health, he asked what he should do. The answer: get a heart scan.
Measure the disease with the easiest test available. If his heart scan score is zero, great--he's at exceptionally low (near zero) risk for heart attack. A modest program of long-term prevention is all that's necessary. What if his score is like his brother, should he get in line for his bypass? No, absolutely not! But he will need two things: 1) a stress test to ascertain whether or not he's safe (60% likelihood a stress test would be normal), and 2) an effort to determine how the heck he got so much plaque. (We favor lipoprotein testing, of course, for greatest diagnostic certainty.)
Message: Learn from the lessons your own family provides. Don't let this valuable information go to waste.

Why does wheat cause arthritis?

13. November 2010 William Davis (48)
Wheat causes arthritis.

Before you say "What the hell is he saying now?", let me connect the dots on how this ubiquitous dietary ingredient accelerates the path to arthritis in its many forms.

1) Wheat causes glycation--Glycation is glucose-modification of proteins in the body that occurs when blood glucose exceeds 100 mg/dl. Cartilage cells are especially susceptible to glycation. The cartilage cells you had at age 18 are the very same cartilage cells you have at age 60, since they lack the ability to reproduce and repair themselves. Proteins in cartilage are highly susceptible to glycation, which makes them stiff and brittle. Stiff, brittle cartilage loses its soft, elastic, lubricating function. Damaged cartilage cells don't regenerate nor produce more protective proteins. This allows destruction of cartilage tissue, inflammation, and, eventually, bone-on-bone arthritis.

Because wheat, even whole wheat, sends blood sugar higher than almost all other foods, from table sugar to Snickers bars, glycation occurs after each and every slice of toast, every whole wheat bagel, every pita wrap.

2) Wheat is acidifying--Humans are meant to consume a diet that is net alkaline. While hunter-gatherers who consume meat along with plentiful vegetables and fruits live a net alkaline diet (urine pH 7 to 9), modern humans who consume insufficient vegetables and too much grain (of which more than 90% is usually wheat) shift the body towards net acid (urine pH 5 to 7). Wheat is The Great Disrupter, upsetting the normal pH balance that causes loss of calcium from bones, resulting in decalcification, weakness, arthritis and osteoporotic fractures.

3) Wheat causes visceral fat--The extravagant glucose-insulin surges triggered by wheat leads to accumulation of visceral fat: wheat belly.

Visceral fat not only releases inflammatory mediators like tumor necrosis factor and various interleukins, but is also itself inflamed. The inflammatory hotbed of the wheat belly leads to inflammation of joint tissues. This is why overweight and obese wheat-consuming people have more arthritis than would be explained by the burden of excess weight: inflammation makes it worse. Conversely, weight loss leads to greater relief from arthritis pain and inflammation than would be explained by just lightening the physical load.

We need a name for this wheat effect. How about "bagel bones"?

Why do morphine-blocking drugs make you lose weight?

10. November 2010 William Davis (24)
Naloxone (IV) and naltrexone (oral) are drugs that block the action of morphine.

If you were an inner city heroine addict and got knifed during a drug deal, you'd be dragged into the local emergency room. You're high, irrational, and combative. The ER staff restrain you, inject you with naloxone and you are instantly not high. Or, if you overdosed on morphine and stopped breathing, an injection of naloxone would reverse the effect immediately, making you sit bolt upright and wondering what the heck was going on.

So what do morphine-blocking drugs have to do with weight loss?

An odd series of clinical studies conducted over the past 40 years has demonstrated that foods can have opiate-like properties. Opiate blockers, like naloxone, can thereby block appetite. One such study demonstrated 28% reduction in caloric intake after naloxone administration. But opiate blocking drugs don't block desire for all foods, just some.

What food is known to be broken down into opiate-like polypeptides?

Wheat. On digestion in the gastrointestinal tract, wheat gluten is broken down into a collection of polypeptides that are released into the bloodstream. These gluten-derived polypeptides are able to cross the blood-brain barrier and enter the brain. Their binding to brain cells can be blocked by naloxone or naltrexone administration. These polypeptides have been named exorphins, since they exert morphine-like activity on the brain. While you may not be "high," many people experience a subtle reward, a low-grade pleasure or euphoria.

For the same reasons, 30% of people who stop consuming wheat experience withdrawal, i.e., sadness, mental fog, and fatigue.

Wouldn't you know that the pharmaceutical industry would eventually catch on? Drug company startup, Orexigen, will be making FDA application for its drug, Contrave, a combination of naltrexone and the antidepressant, buproprion. It is billed as a blocker of the "mesolimbic reward system" that enhances weight loss.

Step back a moment and think about this: We are urged by the USDA and other "official" sources of nutritional advice to eat more "healthy whole grains." Such advice creates a nation of obese Americans, many the unwitting victims of the new generation of exorphin-generating, high-yield dwarf mutant wheat. A desperate, obese public now turns to the drug industry to provide drugs that can turn off the addictive behavior of the USDA-endorsed food.

There is no question that wheat has addictive properties. You will soon be able to take a drug to block its effects. That way, the food industry profits, the drug industry profits, and you pay for it all.

Heart scan tomfoolery 2

9. November 2010 William Davis (2)
In the last Heart Scan Blog post, I discussed the significance of the apparent discrepancy between Steve's heart scan score and volume score. This post addresses his second question, also a FAQ about heart scan scores.

Steve noted that his second scan compared to his first showed:

- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

So there are apparent divergences in behavior in the left main that increased and both LAD (left anterior descending) and LCX (left circumflex) that decreased.

The explanation is simple: When heart scans are "scored," they are viewed in horizontal "slices." When the heart is viewed as horizontal slices, the LAD and LCX originate from the common left main stem. In other words, it's like a tree with the left mainsteam representing the trunk, the LAD and LCX representing two main branches.

Plaque can form, obviously, in all three arteries, but it can do so by starting in the left main, for instance, and extending into either the LAD or LCX, or both. The left main plaque can therefore bridge any 2 or all 3 arteries.

When the plaque is "scored" by taking the computer mouse and circling the calcified plaque in question (to allow the computer program to generate the calcium score and volume score of that particular plaque), the plaque that may extend from left main into the LAD and/or LCX might be labeled "left main," or it might be labeled "LAD" or "LCX." There is no reliable way to "dissect" apart the plaque into the three arteries, since the plaque is coalescent and continuous. So the scoring technologist or physician simply arbitrarily declares the artery "LAD," for instance.

The problem comes when two different interpretation methods are used: Perhaps it's a new technologist or physician, or there was no attention paid to how the previous scan was read. One reader calls it "left main" and the next calls it "LCX."

So the apparent discrepancy has to do with flaws in the methods of segregating plaque location, as well as inattention to scoring techniques. The total score, however, remains unaffected.

Nonetheless, Steve has enjoyed a modest reduction in the score of the left main/LAD/LCX from his original 140.8 down to a second left main/LAD/LCX score of 126.9.

The right coronary artery (RCA), however, is not subject to this difficulty and Steve score shows a modest increase in score. (Why the divergent behavior between left main/LAD/LCX and RCA? There is no clear explanation for this, unfortunately.)

All in all, the news for Steve is good: He achieved these results on his own using nutritional techniques. Because he, in all practicality, stopped the progression of his heart scan score and avoided the "natural" rate of increase of 30% per year, all he needs to do is "tweak" his program a bit to achieve reversal, i.e., reduction of score.


Here's an image from another previous Heart Scan Blog post (about the relationship of osteoporosis and coronary disease) that shows such a plaque that starts in the left mainstem yet extends into both the LAD and LCX:

Heart scan tomfoolery

4. November 2010 William Davis (12)
Heart Scan Blog reader, Steve, sent these interesting questions about his heart scan experience. (I sometimes forget that this blog is called "The Heart Scan Blog" and was originally--several years ago--meant to discuss heart scans. It has evolved to become a much broader conversation.)

The answers are a bit lengthy, so I'll tackle Steve's questions in two parts, the second in another blog post.

Dr. Davis,

I had a heart scan last year. The score was 96. While not a horrible score, it
was a wake up call, and I changed my lifestyle.

I had another scan this year and the heart scan score went up to 105, but the
volume score went down from 141 to 136.

The report I received said this:

'The calcium volume score is less in the current study as compared with the
original or reference study. This is an excellent coronary result and indicates
that there has been a net decrease in coronary plaque burden. The current
prevention program is very effective and should be continued.'

This is all well and good, but I have two questions:

1. Am I really going in the right direction even though the heart scan score
went up 9%?

2. Here are results that make no sense to me:
- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

Why would there be so much variation from year to year, and why would the plaque
move from site to site?

Steve

Questions like Steve's come up with some frequency, so I thought it would be worthwhile to discuss in a blog post.

First of all, the conventional heart scan score, or "calcium score" or "Agatston score" (after Dr. Arthur Agatston, developer of the simple algorithm for calcium scoring, as well as South Beach Diet fame), is the product of the area of the plaque in a single CT "slice" image
multiplied by a density coefficient, i.e., a number ranging from 1 to 4 that grades the x-ray density of the plaque. (1 is least dense; 4 is most dense.) A density coefficient of 1 therefore signifies some calcium within plaque, with higher density coefficients signifying increasing calcium content and density. Incidentally, "soft" plaque, i.e., non-calcified, would fall in the less than 1 range, even the negative range (fatty tissue within plaque).

The volume, or "volumetric," score is the brainchild of Drs. Paulo Raggi and Traci Callister, who expressed concern that, if we cause plaque to shrink in volume, the density coefficient used to calculate the calcium score would increase (since they believed that calcium could not be reduced, contrary to our Track Your Plaque experience, thereby leading to misleading results. They therefore developed an algorithm that did not rely on density coefficients, but used the same two-dimensional area obtained in the standard heart scan score, but replaced the density coefficient with a (mathematically interpolated) vertical axis (z-axis) measure of plaque "height." This 3-dimensional volumetric value therefore provided a method to generate a measure of calcium volume. In their original publication, the volume score proved more reproducible than the standard calcium score. This way, any reduction in plaque volume would not be influenced by the misleading effects of calcium density, but reflect a real reduction in volume.

Callister and Raggi's study also highlighted that calcium scoring in any form is subject to variability. Back in 1998 (when their study was published), there was a bit more variation than today due to the image acquisition methods used. But, even today, there is about 9% variation in scoring even if performed repeatedly (with less percentage variation the higher the score).

Unfortunately, volume scoring never caught on and the calcium score has been the most commonly used value by most heart scan centers and in most clinical studies. And, in all practicality, the two values nearly always track together: When calcium score increases, volume score increases in tandem; when calcium score decreases, volume score decreases in tandem.

Steve is therefore an exception to the general observation that calcium score and volume score travel together. Steve's calcium score increased, while his volume score decreased. From the above discussion, you can surmise a few things about Steve's experience:"

1) In all likelihood, the changes in both calcium score and volume score could simply be due to variability, i.e., variation in the placement of his body on the scan table, variation in position of the heart, variation in data acquisition, etc. There is a high likelihood that neither value changed; both are essentially unchanged.

2) If the changes are not due to scan variability, but are real, then it could be that the calcified plaque is reduced in volume but increased in density. If true, this is probably still a favorable phenomenon, since plaque volume is a powerful predictor of coronary "events" and an increase in plaque density is likely a benign phenomenon. It would also raise questions about the adequacy of vitamin D and vitamin K2 status, both major control factors over calcium deposition and metabolism.

So, in all likelihood, Steve's apparent discrepant results are modest good news, especially since calcium scores can ordinarily be expected to increase at the rate of 30% per year if no action is taken. Experiencing no change in score, calcium or volumetric, carries a very excellent prognosis, with risk for heart attack approaching zero. (I'm impressed that Steve accomplished this on his own, something the majority of my colleagues haven't the least bit of interest doing.)

Part 2 of Steve's question will be tackled in a separate post.

Can I see your linea alba?

2. November 2010 William Davis (19)
As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba.

Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen.

It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors.


Can you see your linea alba?

Dwarf mutant wheat

31. October 2010 William Davis (13)
Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.

Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant. 

Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to. 





The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans.

Medical education in the days of Big Pharma

30. October 2010 William Davis (43)
I received this detailed email from an unexpected source: a 3rd-year medical student.

In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life.

Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat.

While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career.


Dr. Davis,

I am a 3rd year medical student at ________ University. I came across
your blog today, and I'm very glad I did. I appreciate the value of your time,
so I want to be as succinct as possible while still getting across what I'm
really thinking and feeling:

From what I gathered exploring your blog for a while this afternoon, the
wellness strategies you incorporate into your practice are some of the exact
things I want to do with my future patients. Personally, I strongly believe in
staying healthy by eating right, staying active, etc. For instance, I don't eat
grains or much in the way of starches and sugars. So I love the fact that you
are helping your patients make these powerful and foundational changes in their
lives.

As I'm sure was your experience, a full appreciation of nutrition and lifestyle
as a first-line health strategy is not something that was taught to me in
medical school. I came to school with this deep conviction already in my heart
and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss
as to how I'm going to be able to practice medicine the way I want to, which is
to incorporate these all-important principles into the care of my patients.

What I've come to understand about the medical field today is that the
information that exists is primarily subsidized by the pharmaceutical industry,
and dictated to medical professionals as "evidence-based" treatment guidelines
and recommendations by organizations with sincere and official sounding names
like American Heart Association and American Cancer Society. Add to that the
pressure of potential malpractice litigation and the complexities of the
insurance reimbursement game, and it seems to me like what you get is a bunch of
diagnostic and medication management algorithms that any half-trained monkey
could follow. In his sleep. Which I guess would be alright if at least they
weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma,
Food Inc, insurance conglomerates, and agri-politics (I think I just made that
word up.)

A lot of well-intentioned physicians are just parroting the party
line, as their patients dutifully and gratefully chomp down their statins and
diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes
education" programs with curriculum put together by drug companies? How is that
even legal? Massive corporations raking in massive profits that are dependent
on uncontrolled blood sugars telling people how to best control their blood
sugars?!

Anyway, forgive my rant. What I'm getting at is this: How can I practice
medicine, with the freedom to educate/coach/treat my patients with diet and
lifestyle changes to mitigate/reverse their chronic health conditions? Without
feeling like I automatically have to first and foremost prescribe the litany of
drugs dictated by "evidence-based" guidelines? Without excessive fear of
litigation or loss of credibility among my peers? Without having to lie through
my teeth to my patients, and tell them that eating low-fat and heart-healthy
whole grains is the best way (implication also being the only scientifically
proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?

I want my patients to have the full benefit of honest nutrition and lifestyle
information, and medications and surgery as necessary. I'm afraid that there
isn't room for this kind of holistic emphasis in the medical profession today.
Are there residencies that include this kind of training or at least respect
these "unconventional" philosophies? Are there clinics or practice groups that
would allow me to practice with this emphasis, or is there a bias against docs
who do not necessarily conform to the party position? Will I have no other
option but to go it alone under the auspices of my own shingle? How do you
handle these kinds of issues in your professional life?

Sincerely,
Theresa M.


A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets.

I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often.

The Great Low-Carb Connector

28. October 2010 William Davis (15)
The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.

Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:

My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!

This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”

Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible.

New Track Your Plaque record!

27. October 2010 William Davis (19)
The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score.

Well, the longstanding record was broken this week: 75% reduction in score.

At the start, Freddie has disastrous lipid values:

LDL cholesterol 263 mg/dl
HDL 26 mg/dl
Triglycerides 323 mg/dl
Total cholesterol 354 mg/dl

Lipoproteins (NMR) were worse:

LDL particle number 3360 nmol/L
Small LDL 2677 nmol/L

Heart scan score: 732

Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable.

Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me.

Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight.

43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction.

While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees.

The Anti-AGEing Diet

22. October 2010 William Davis (36)
Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck.

There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others.

One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)

There are two general ways to develop AGEs:

1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months.

A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation.

2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi.

The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation.

Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food.

If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy.

The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs.
