Are you hungry?

6. December 2011 William Davis (43)

Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

Chocolate . . . for adults only

30. November 2011 William Davis (22)

If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.

I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

19. November 2011 William Davis (29)

At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

14. November 2011 William Davis (73)

More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Lessons from the 20-year statin experience

2. November 2011 William Davis (0)

Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages.

Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:

Small LDL particles and increased HbA1c--An evil duo

30. October 2011 William Davis (53)

Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

Unforgiving small LDL particles

21. October 2011 William Davis (39)

Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.

A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.

In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particles, carbohydrate reduction results in marked reduction in small LDL particle formation.

So let's say you are doing great and you've slashed carbohydrates. Small LDL particles are now down to zero--no small LDL whatsoever. What LDL particles you have are the more benign large variety, say, 1200 nmol/L (LDL particle number), all large, none small. You are due for some more blood work on Thursday. On Tuesday, however, you have four crackers because, what the heck, you've been doing great, you've lost 43 pounds, and have been enjoying dramatic correction of your lipoprotein abnormalities.

Your next lipoprotein panel: LDL particle number 1800 nmol/L, small LDL 700 nmo/L--substantially worse, with a major uptick in small LDL.

That's how sensitive small LDL particles can be to carbohydrate intake. And the small LDL particles can last for up to several days, since small LDL particles are not just smaller in size, they also differ in conformation, making them unrecognizable by the normal liver receptor. The small LDL particles triggered by the 4 crackers therefore linger, outlasting the normal-conformation large LDL particles that are readily cleared by the liver.

This phenomenon is responsible for great confusion when following lipoprotein panels, since a 98% perfect diet can yield dismaying results just from a minor indulgence. But, buried in this simple observation is the notion that small LDL particles are also extremely unforgiving, being triggered by the smallest carbohydrate indulgence, lasting longer and wreaking their atherosclerotic plaque havoc.

I eliminated wheat . . . and I didn't lose weight!

19. October 2011 William Davis (33)

Elimination of wheat is a wonderfully effective way to lose weight. Because saying goodbye to wheat means removing the gliadin protein of wheat, the protein degraded to brain-active exorphins that stimulate appetite, calorie consumption is reduced, on average, 400 calories per day. It also means eliminating this source of high blood sugar and high blood insulin and the 90-minutes cycles of highs and lows that cause a cyclic need to eat more at the inevitable low. It means that the high blood sugar and insulin phenomena that trigger accumulation of visceral fat are now turned off. It may possibly also mean that wheat lectins no longer block the leptin receptor, undoing leptin resistance and allowing weight loss to proceed. And weight loss usually results effortlessly and rapidly.

But not always. Why? Why are there people who, even after eliminating this appetite-stimulating, insulin-triggering, leptin-blocking food, still cannot lose weight? Or stall after an initial few pounds?

There are a list of reasons, but here are the biggies:

1) Too many carbohydrates--What if I eliminate wheat but replace those calories with gluten-free breads, muffins, and cookies? Then I've switched one glucose-insulin triggering food for another. This is among the reasons I condemn gluten-free foods made with rice starch, cornstarch, tapioca starch, and potato starch. Or perhaps there's too many potatoes, rices, and oats in your diet. While not as harmful as wheat, they still provoke phenomena that cause weight loss to stall. So cutting carbohydrates may become necessary, e.g., no more than 12-14 grams per meal.

2) Fructose--Fructose has become ubiquitous and has even assumed some healthy-appearing forms. "Organic agave nectar" is, by far, the worst, followed by maple syrup, honey, high-fructose corn syrup, sucrose,and fruit--yes, in that order. They are all sources of fructose that causes insulin resistance, visceral fat accumulation or persistency, prolongation of clearing postprandial (after-meal) lipoproteins that antagonize insulin, and glycation. Lose the fructose sources--as much of it as possible. (Fruit should be eaten in very small portions.) Watch for stealth sources like low-fat salad dressings--you shouldn't be limiting your fat anyway!

3) Thyroid dysfunction--A real biggie. Number one cause to consider for thyroid dysfunction: iodine deficiency. Yes, it's coming back in all its glory, just like the early 20th century before iodized salt made it to market shelves. Now, people are cutting back on iodized salt. Guess what's coming back? Iodine deficiency and even goiters. Yes, goiters, the disfiguring growths on the neck that you thought you'd only see in National Geographic pictures of malnourished native Africans. Number two: Exposure to factors that block the thyroid. This may include wheat, but certainly includes perchlorate residues (synthetic fertilizer residues) on produce, pesticides, herbicides, polyfluorooctanoic acid residues from non-stick cookware, polybrominated diphenyl ethers (flame retardants), and on and on. If you are iodine-deficient, it can even include goitrogenic iodine-blocking foods like broccoli, cauliflower, and soy. Thyroid status therefore needs to be assessed.

4) Cortisol--Not so much excess cortisol as disruptions of circadian rhythm. Cortisol should surge in the morning, part of the process to arouse you from sleep, then decline to lower levels in the evening to allow normal recuperative sleep. But this natural circadian cycling is lost in many people represented, for instance, as a flip-flopping of the pattern with low levels in the morning (with morning fatigue) and high levels at bedtime (with insomnia), which can result in stalled weight loss or weight gain. Cortisol status therefore needs to be assessed, best accomplished with salivary cortisol assessment.

5) Leptin resistance--People who are overweight develop an inappropriate resistance to the hormone, leptin, which can present difficulty in losing weight. This can be a substantial issue and is not always easy to overcome. It might mean assessing leptin levels or it might mean taking some steps to overcome leptin resistance.

Okay, that's a lot. Next: More on how to know when thyroid dysfunction is to blame.

Do the math: 41.7 pounds per year

14. October 2011 William Davis (21)

Consumers of wheat take in, on average, 400 calories more per day. Conversely, people who eliminate wheat consume, on average, 400 calories less per day.

400 calories per day multiplied by 365 days per day equals 146,000 additional calories over the course of one year. 146,000 calories over a year equals 41.7 pounds gained per year. Over a decade, that's 417 pounds. Of course, few people actually gain this much weight over 10 years.

But this is the battle most people who follow conventional advice to "cut your fat and eat more healthy whole grains" are fighting, the constant struggle to subdue the appetite-increasing effects of the gliadin protein of wheat, pushing your appetite buttons to consume more . . . and more, and more, fighting to minimize the impact.

So, if you eat "healthy whole grains" and gain "only" 10 pounds this year, that's an incredible success, since it means that you have avoided gaining the additional 31.7 pounds that could have accumulated. It might mean having to skip meals despite your cravings, or exercising longer and harder, or sticking your finger down your throat.

400 additional calories per day times 365 days per year times 300,000,000 people in the U.S. alone . . . that's a lot of dough. Is this entire scenario an accident?

Or, of course, you could avoid the entire situation and kiss wheat goodbye . . . and lose 20, 30, or 130 pounds this year.

We got the drug industry we deserve

14. October 2011 William Davis (6)

A biting commentary on just who is writing treatment guidelines for diabetes and cardiovascular disease was published in the British Medical Journal, summarized in theHeart.org's HeartWire here.

"About half the experts serving on the committees that wrote national clinical guidelines for diabetes and hyperlipidemia over the past decade had potential financial conflicts of interest (COI), and about 4% had conflicts that were not disclosed.

"Five of the guidelines did not include a declaration of the panel members' conflicts of interest, but 138 of the 288 panel members (48%) reported conflicts of interest at the time of the publication of the guideline. Eight reported more than one conflict. Of those who declared conflicts, 93% reported receiving honoraria, speaker's fees, and/or other kinds of payments or stock ownership from drug manufacturers with an interest in diabetes or hyperlipidemia, and 7% reported receiving only research funding. Six panelists who declared conflicts were chairs of their committee.

"Of the 73 panelists who had a chance to declare a conflict of interest but declared none, eight had undeclared COI that the researchers identified by searching other sources. Among the 77 panel members who did not have an opportunity to publicly declare COI in the guidelines documents, four were found to have COI."

The closing quote by Dr. Edwin Gale of the UK is priceless:
"Legislation will not change the situation, for the smart money is always one step ahead. What is needed is a change of culture in which serving two masters becomes as socially unacceptable as smoking a cigarette. Until then, the drug industry will continue to model its behavior on that of its consumers, and we will continue to get the drug industry we deserve."

It's like having Kellogg's tell us what to each for breakfast, or Toyota telling us what car to drive. The sway of the drug industry is huge. Even to this day, I observe colleagues kowtow to the sexy sales rep hawking her wares. But that's the least of it. Far worse, even the "experts" who we had trusted to have objectively reviewed the evidence to help the practitioner on Main Street appears to be little more than a hired lackey for Big Pharma, hoping for that extra few hundred thousand dollars.

Green Tea Ginger Orange Bread

11. July 2012 William Davis (4)

How about all the health benefits of green tea in wheat-free bread form, spiced up with the magical combined flavors of ginger and orange?

Frequent consumption of green tea accelerates loss of visceral (“wheat belly”) fat, increases HDL and reduces triglycerides, reduces blood pressure, and may provide cardiovascular benefits that go beyond these markers such as reduction of oxidative stress. In this Green Tea Ginger Orange Bread, we don’t just drink the tea—we eat it! This provides an even more powerful dose of the green tea catechins believed to be responsible for the health benefits of green tea.

You can grind your own green tea from dried bulk leaves or it can be purchased pre-ground. I’ve used sencha and matcha green tea varieties with good results. The Teavana tea store sells a Sencha preground green tea that works well. If starting with bulk tea leaves, pulse in your food chopper, food processor, or coffee grinder (cleaned thoroughly first!) to generate green tea powder. You will need only a bit, as a little goes a long way.

The entire loaf contains 26 grams “net” carbohydrates; if cut into 10 slices, each slice therefore yields 2.6 grams net carbs, a perfectly tolerable amount.

Bread:
1¼ cup almond meal/flour
½ cup coconut flour
2 tablespoons ground golden flaxseed
1 teaspoon baking powder
Sweetener equivalent to 1 cup sugar
1 tablespoon ground green tea
1½ teaspoons ground ginger
1½ teaspoons ground allspice
1½ ground cinnamon
2 large eggs, separated
¼ teaspoon cream of tartar
1 tablespoon vanilla extract
1 teaspoon almond extract
Grated zest from 1 orange + 2 tablespoons squeezed juice
1/2 cup coconut milk

Frosting:
4 ounces cream cheese, room temperature
1 teaspoon fresh lemon juice
Sweetener equivalent to 1 tablespoon sugar

Preheat oven to 350° F. Grease a 9” x 5” bread pan.

In large bowl, combine almond meal/flour, coconut flour, flaxseed, baking powder, sweetener, green tea, ginger, allspice, and cinnamon and mix.

In small bowl, whip egg whites and cream of tartar until stiff peaks form. At low mixer speed, blend in egg yolks, vanilla extract, almond extract, orange zest and juice, and coconut milk.

Pour egg mixture into almond meal/flour mixture and mix by hand thoroughly.

Pour dough into bread pan and place in oven. Bake for 40 minutes or until toothpick withdraws dry. Remove and cool.

For frosting, combine cream cheese, lemon juice, and sweetener and mix. When cooled, spread frosting over top of bread.

Chocolate Bomb Bars

10. July 2012 William Davis (4)

These healthy bars will blast you with chocolate from several directions!

Look for cacao nibs in health food stores, Whole Foods Market, or at nuts.com. If unavailable, the bars are still delicious without them.

These bars contain around 4-5 grams "net" carbs per bar, well within the tolerance for most people.

Yields approximately 10 bars

1 cup ground almonds
2 tablespoons coconut flour
1 tablespoon unsweetened cocoa powder
1/2 cup cacao nibs
1/2 cup unsweetened shredded coconut
2 ounces 85-90% cocoa chocolate, finely chopped
3/4 cup raw pumpkin or sunflower seeds
Sweetener equivalent to 3/4 cup sugar
2 tablespoons almond butter
1/4 cup coconut milk
2 tablespoons coconut oil or cocoa butter (food grade)

Preheat oven to 200 degrees F. Lay sheet of parchment paper on large baking pan.

In large bowl, combine ground almonds, coconut flour, cocoa powder, cacao nibs, coconut, chocolate bits, pumpkin seeds, and sweetener (if dry) and mix.

In microwave-safe bowl or in small sauce pan, add almond butter, coconut milk, and coconut oil and sweetener (if liquid) and heat for 15 second increments in microwave until liquid, but not hot. If using stove, heat at low-heat enough to make liquid easily mixed, but not hot.

Pour liquid into dry almond mixture and mix together thoroughly. If too stiff, add water one tablespoon at at time until the consistency of thick dough.

Spoon out approximately 1 1/2-inch balls, shaping with the spoon and/or your hands into bar shapes.

Bake for 35 minutes. Remove and cool.

An iodine primer

10. July 2012 William Davis (7)

What if your diet is perfect--no wheat, no junk carbohydrates like that from corn or sugars, you are physically active--yet you fail to lose weight? Or you hit a plateau after an initial loss?

First think iodine.

Iodine is an essential nutrient. It is no more optional than, say, celebrating your wedding anniversary or obtaining vitamin C. If you forget to do something nice for your wife on your wedding anniversary, I would fear for your life. If you develop open sores all over your body and your joints fall apart, you could undergo extensive plastic surgery reconstruction and joint replacement . . . or you could just treat the scurvy causing it from lack of vitamin C.

Likewise iodine: If you have an iodine deficiency, you experience lower thyroid hormone production, since T3 and T4 thyroid hormones require iodine (the "3" and "4" refer to the number of iodine atoms per thyroid hormone molecule). This leads to lower energy (since the thyroid controls metabolic rate), cold hands and feet (since the thyroid is thermoregulatory, i.e., temperature regulating), and failed weight loss. So iodine deficiency is one of the items on the list of issues to consider if you eliminate wheat with its appetite-stimulating opiate, gliadin, and high-glycemic carbohydrate, amylopectin A, and limit other carbohydrates, yet still fail to lose weight. A perfect diet will not fully overcome the metabolism-limiting effects of an underactive thyroid.

Given sufficient time, an enlarged thyroid gland, or goiter, develops, signaling longstanding iodine deficiency. (The treatment? Iodine, of course, not thyroid removal, as many endocrinologists advocate.) Your risk for heart attack, by the way, in the presence of a goiter is increased several-fold. Goiters are becoming increasingly common and I see several each week in my office.

Iodine is found in the ocean and thereby anything that comes from the ocean, such as seafood and seaweed. Iodine also leaches into the soil but only does so coastally. It means that crops and livestock grown along the coasts have some quantity of iodine. Humans hunting and foraging along the coast will be sufficient in iodine, while populations migrating inland will not.

It also means that foods grown inland do not have iodine. This odd distribution for us land dwelling primates means that goiters are exceptionally common unless iodine is supplemented. Up to 25% of the population can develop goiters without iodine supplementation, a larger percentage experiencing lesser degrees of iodine deficiency without goiter.

In 1924, the FDA became aware of the studies that linked goiters to lack of iodine, reversed with iodine supplementation. That's why they passed a regulation encouraging salt manufacturers to add iodine, thought to be an easy and effective means for an uneducated, rural populace to obtain this essential nutrient. Their message: "Use more iodized salt. Keep your family goiter free!" That was actually the slogan on the Morton's iodized salt label, too.

It worked. The rampant goiters of the first half of the 20th century disappeared. Iodized salt was declared an incredible public health success story. Use more salt, use more salt.

You know the rest. Overuse of salt led to other issues, such as hypertension in genetically susceptible people, water retention, and other conditions of sodium overexposure. The FDA then advises Americans to slash their intake of sodium and salt . . . but make no mention of iodine.

So what recurs? Iodine deficiency and goiters. Sure, you eat seafood once or twice per week, maybe even have the nori (sheet seaweed) on your sushi once in a while . . . but that won't do it for most. Maybe you even sneak some iodized salt into your diet, but occasional use is insufficient, especially since the canister of iodized salt only contains iodine for around 4 weeks, given iodine's volatile nature. (Iodized salt did work when everybody in the house salted their food liberally and Mom had to buy a new canister every few weeks.)

Iodine deficiency is common and increasing in prevalence, given the widespread avoidance of iodized salt. So what happens when you become iodine deficient? Here's a partial list:

--Weight loss is stalled or you gain weight despite your efforts.
--Heart disease risk is escalated
--Total and LDL cholesterol and triglyceride values increase
--Risk of fibrocystic breast disease and possibly breast cancer increase (breast tissue concentrates iodine)
--Gingivitis and poor oral health increase (salivary glands concentrate iodine)

(Naturopathic doctor Lyn Patrick, ND, has written a very nice summary available here.)

So how do you ensure that you obtain sufficient iodine every day? You could, of course, eat something from the ocean every day, such as coastal populations such as the Japanese do. Or you could take an inexpensive iodine supplement. You can get iodine in a multivitamin, multimineral, or iodine drops, tablets, or capsules.

What is the dose? Here's where we get very iffy. We know that the Recommended Daily Allowance (RDA), the intake to not have a goiter, is 150 mcg per day for adults (220 mcg for pregnant females, 290 mcg for lactating females). Most supplements therefore contain this quantity.

But what if our question is what is the quantity of iodine required for ideal thyroid function and overall health? Ah, that's where the data are sketchy. We know, for instance, that the Japanese obtain somewhere between 3,500 and 13,000 mcg per day (varying widely due to different habits and locations). Are they healthier than us? Yes, quite a bit healthier, though there may be other effects to account for this, such as a culture of less sweet foods and more salty, less wheat consumption, etc. There are advocates in the U.S., such as Dr. David Brownstein in Michigan, who argues that some people benefit by taking doses in the 30,000 to 50,000 mcg per day range (monitored with urinary iodine levels).

As is often the case with nutrients, we lack data to help us decide where the truly ideal level of intake lies. So I have been using and advocating intakes of 500 to 1000 mcg per day from iodine capsules, tablets, or drops. A very easy way to get this dose of iodine is in the form of kelp tablets, i.e., dried seaweed, essentially mimicking the natural means of intake that also provides iodine in all its varied forms (iodide, sodium iodate, potassium iodide, potassium iodate, iodinated proteins, etc.) This has worked out well with no ill effects.

The only concern with iodine is in people with Hashimoto's thyroiditis or (rarely) an overactive thyroid nodule. Anyone with these conditions should only undertake iodine replacement carefully and under supervision (monitoring thyroid hormone levels).

Iodine is inexpensive, safe, and essential to health and weight management. If it were a drug, it would enjoy repeated expensive marketing and a price tag around $150 per month. But it is an essential nutrient that enjoys none of the attention-getting advantages of drugs, and therefore is unlikely to be mentioned by your doctor, yet carries great advantage for helping to maintain overall health.

Green coffee bean extract in AGF Factor I

Track Your Plaque's new and proprietary formulation, AGF Factor I, is designed to to support a program to achieve low levels of endogenous glycation.

Endogenous glycation, discussed at length in a recent Track Your Plaque Special Report, makes LDL particles (especially small LDL particles) more prone to oxidation and thereby more atherogenic, i.e., more likely to contribute to atherosclerotic plaque. Endogenous glycation also exerts unhealthy effects on long-lived proteins in the body, such as the proteins in the lenses of your eyes (cataracts), the lining of arteries (hypertension), and the cartilage cells of joints (brittle cartilage and arthritis).

Endogenous glycation is reduced by slashing carbohydrates in the diet, especially the most offensive carbohydrates of all, the amylopectin A of wheat, sucrose, high-fructose corn syrup and other fructose sources. Endogenous glycation can also be blocked by using blockers of the glycation reaction, such as benfotiamine (lipid-soluble thiamine), pyridoxal-5'-phosphate (a form of vitamin B6 with greater glycation blocking effect), and chlorogenic acid from green coffee beans, all components of AGF Factor I, which also contains Portulaca oleracea (Portusana), or purslane, for reduction of glucose.

Green coffee bean extract, and thereby chlorogenic acid, is receiving increased attention, most recently due to a study demonstrating substantial weight loss with 750-1050 mg green coffee bean extract, providing approximately 325-500 mg chlorogenic acid per day. Participants lost 15.4 pounds over 8 weeks at the higher dose (500 mg chlorogenic acid per day), while participants lost 8.8 pounds over 8 weeks at the lower dose (325 mg chlorogenic acid per day).

AGF Factor I was not formulated for weight loss but, taken twice or three times per day, does indeed mimic the dose of chlorogenic acid from green coffee bean extract used in the weight loss study. If you wish to take advantage of this application of chlorogenic acid/green coffee bean extract, while also maximizing protection from endogenous glycation, our AGF Factor I is one excellent choice to do so.

Lessons learned from the 2012 Low-carb Cruise

14. May 2012 William Davis (13)

I just returned from Jimmy Moore's Low-carb Cruise, a 7-day excursion to Jamaica, Grand Cayman Island, and Cozumel aboard the Carnival Magic. During our 7 wonderful days, a number of authors and experts spoke, each offering their unique perspective on the low-carb world. The focus was the science, experience, and practical application of low-carbohydrate diets.

The event kicked off with a roast by Tom Naughton of Fat Head fame, who entertained with his insightful low-carb humor and predictions of my demise at the hands of Monsanto!

Among the most important lessons provided:

Dr. Andreas Eenfeldt of the Diet Doctor blog discussed how Sweden is leading the world as the nation with the most vigorous low-carbohydrate following, witnessing incredible weight loss and reversal of carbohydrate-related diseases way ahead of the U.S. experience. I spent several hours with Dr. Eenfeldt who, besides being an engaging speaker, is a new father and an all-around gentleman. At 6 ft, 7 inches, he also towered high above all of us.

Dr. Eric Westman of Duke University and author of The New Atkins for a New You, debunked low-carbohydrate myths, such as "low-carb diets are high-protein diets that make your kidneys explode."

Dr. John Briffa, creator of the popular blog, Dr. John Briffa: A Good Look at Good Health, and author of the wonderfully straightforward primer to low-carbohydrate eating, Escape the Diet Trap, stressed the importance of never allowing hunger to rule behavior. Dr. Briffa's serious writing tone conceals an incredible charm and wit that took me by surprise, having spent several thoroughly engaging hours over breakfast, lunch, and dinner with him over the week.

Fred Hahn, exercise expert, founder of Serious Strength and author of Slow Burn Fitness Revolution and Strong Kids, Healthy Kids, debunked a number of trendy exercise methods, boiling many of the purported benefits of exercise down to that of increased strength.

Dr. Chris Masterjohn of The Daily Lipid and supporter of the Weston A. Price Foundation program, provided a comprehensive overview of the data that fails to link saturated fat with heart disease. He also helped me understand the analytical techniques used in studies of advanced glycation end-products.

Denise Minger, brilliant young usurper of China Study dogma and blogger at Raw Foods SOS, proved an engaging speaker and a truly real person (since some critics of her analyses have actually questioned whether there was even such a person!). She also proved every bit as likable as she seems in her captivating blog discussions.

Dr. Jeff Volek, prolific researcher from University of Connecticut, author of over 200 studies validating low-carbohydrate diet effects, and author of the recently released book with Dr. Stephen Phinney, The Art and Science of Low Carbohydrate Living, debunked myths behind carbohydrate dependence and "loading" by athletes. He also talked about how assessing blood ketones may be the gold standard method to ensure low-grade ketosis on a long-term low-carb effort.

Over a bottle of wine, Jimmy Moore and I reminisced over how his modest start with no experience in blogging or media has now ballooned to an audience of over 100,000 readers/viewers.

All in all, Jimmy's Low-carb Cruise experience was worth every minute, with many wonderful lessons and memories!

Chili Sesame Crackers

3. May 2012 William Davis (0)

Looking for something hot and crunchy?

These chili sesame crackers are perfect for dipping into hummus or salsa. As written, the recipe yields a moderately spicy cracker that you can modify readily by increasing or decreasing quantities of cayenne pepper and Tabasco sauce.

This recipe uses sesame seeds as the "flour." Either brown sesame seeds or the lighter version work, though the lighter seeds yield a slightly less bitter flavor with the spices.

For ease of baking, a shallow baking pan measuring 11 x 17 inches works best, as it allows the batter to fill the pan and spread to a cracker thickness. With a smaller pan, you may have to bake in two batches.

Makes approximately 30 chips

2 cups raw sesame seeds
1 cup shredded Parmesan cheese
2 tablespoons extra-virgin olive oil
1 tablespoon chili powder
½ teaspoon cayenne pepper
2 teaspoons onion powder
1 teaspoon garlic powder
1 teaspoon dry mustard
1 teaspoon sea salt
1 teaspoon Tabasco sauce
1¼ cups water

Preheat oven to 350º F.

In food chopper or food processor, grind 1¼ cups sesame seeds to fine meal. Remove and place in large bowl.

Place shredded Parmesan cheese in food chopper or food processor and pulse briefly until reduced to granular consistency. Add to sesame seed meal and mix. Stir in olive oil.

Add remaining (unground) sesame seeds, chili powder, cayenne pepper, onion and garlic powder, mustard, sea salt and mix thoroughly. Add Tabasco sauce and water and mix. Add additional water, if necessary, one tablespoon at a time, to obtain a consistency similar to pancake batter.

Pour mixture into baking pan and smooth to fill pan and obtain a thickness of a cracker. If too thick, remove some batter and re-smooth. Optionally, roll a clean cylindrical glass or bottle over top to smooth and yield a consistent thickness.

Bake for 30 minutes or until edges browned and center firm. If a dry, extra crunchy cracker is designed, bake an additional 10-15 minutes at 250 degrees F.

Remove and allow to cool. Cut with pizza cutter to desired size.

The standard cholesterol panel . . . dissected

18. April 2012 William Davis (0)

There are four values typically reported on any standard cholesterol panel:

Opiate of the masses

18. April 2012 William Davis (22)

Although it is a central premise of the whole Wheat Belly argument and the starting strategy in the New Track Your Plaque Diet, I fear that some people haven't fully gotten the message:

Modern wheat is an opiate.

And, of course, I don't mean that wheat is an opiate in the sense that you like it so much that you feel you are addicted. Wheat is truly addictive.

Wheat is addictive in the sense that it comes to dominate thoughts and behaviors. Wheat is addictive in the sense that, if you don't have any for several hours, you start to get nervous, foggy, tremulous, and start desperately seeking out another "hit" of crackers, bagels, or bread, even if it's the few stale 3-month old crackers at the bottom of the box. Wheat is addictive in the sense that there is a distinct withdrawal syndrome characterized by overwhelming fatigue, mental "fog," inability to exercise, even depression that lasts several days, occasionally several weeks. Wheat is addictive in the sense that the withdrawal process can be provoked by administering an opiate-blocking drug such as naloxone or naltrexone.

But the "high" of wheat is not like the high of heroine, morphine, or Oxycontin. This opiate, while it binds to the opiate receptors of the brain, doesn't make us high. It makes us hungry.

This is the effect exerted by gliadin, the protein in wheat that was inadvertently altered by geneticists in the 1970s during efforts to increase yield. Just a few shifts in amino acids and gliadin in modern high-yield, semi-dwarf wheat became a potent appetite stimulant.

Wheat stimulates appetite. Wheat stimulates calorie consumption: 440 more calories per day, 365 days per year, for every man, woman, and child. (440 calories per person per day is the average.) We experience this, sense the weight gain that is coming and we push our plate away, settle for smaller portions, increase exercise more and more . . . yet continue to gain, and gain, and gain. Ask your friends and neighbors who try to include more "healthy whole grains" in their diet. They exercise, eat a "well-balanced diet" . . . yet gained 10, 20, 30, 70 pounds over the past several years. Accuse your friends of drinking too much Coca Cola by the liter bottle, or being gluttonous at the all-you-can-eat buffet and you will likely receive a black eye. Many of these people are actually trying quite hard to control impulse, appetite, portion control, and weight, but are losing the battle with this appetite-stimulating opiate in wheat.

Ignorance of the gliadin effect of wheat is responsible for the idiocy that emits from the mouths of gastroenterologists like Dr. Peter Green of Columbia University who declares:

"We tell people we don't think a gluten-free diet is a very healthy diet . . . Gluten-free substitutes for food with gluten have added fat and sugar. Celiac patients often gain weight and their cholesterol levels go up. The bulk of the world is eating wheat. The bulk of people who are eating this are doing perfectly well unless they have celiac disease."

In the simple minded thinking of the gastroenterology and celiac world, if you don't have celiac disease, you should eat all the wheat you want . . . and never mind about the appetite-stimulating effects of gliadin, not to mention the intestinal disruption and leakiness generated by wheat lectins, or the high blood sugars and insulin of the amylopectin A of wheat, or the new allergies being generated by the new alpha amylases of modern wheat.

Jelly beans and ice cream

23. March 2012 William Davis (6)

What if I said: "Eliminate all wheat from your diet and replace it with all the jelly beans and ice cream you want."

That would be stupid, wouldn't it? Eliminate one rotten thing in diet--modern high-yield, semi-dwarf wheat products that stimulate appetite (via gliadin), send blood sugar through the roof (via amylopectin A), and disrupt the normal intestinal barriers to foreign substances (via the lectin, wheat germ agglutinin)--and replace it with something else that has its own set of problems, in this case sugary foods. How about a few other stupid replacements: Replace your drunken, foul-mouthed binges with wife beating? Replace cigarette smoking with excessive bourbon?

Sugary carbohydrate-rich foods like jelly beans and ice cream are not good for us because:

1) High blood sugar causes endogenous glycation, i.e, glucose modification of long-lived proteins in the body. Glycate the proteins in the lenses of your eyes, you get cataracts. Glycate cartilage proteins in the cartilage of your hips and knees, you get brittle cartilage that erodes and causes arthritis. Glycate structural proteins in your arteries and you get hypertension (stiff arteries) and atherosclerosis. Small LDL particles--the #1 cause of heart disease in the U.S. today--are both triggered by blood sugar rises and are 8-fold more prone to glycation (and thereby oxidation).

2) High blood sugar is inevitably accompanied by high blood insulin. Repetitive surges in insulin lead to <em>insulin resistance</em>, i.e., muscles, liver, and fat cells unresponsive to insulin. This forces your poor tired pancreas to produce even more insulin, which causes even more insulin resistance, and round and round in a vicious cycle. This leads to visceral fat accumulation (Jelly Bean Belly!), which is highly inflammatory, further worsening insulin resistance via various inflammatory mediators like tumor necrosis factor.

3) Sugary foods, i.e., sucrose- or high-fructose corn syrup-sweetened, are sources of fructose, a truly very, very bad sugar that is metabolized via a completely separate pathway from glucose. Fructose is 10-fold more likely to induce glycation of proteins than glucose. It also provokes a (delayed) rise in insulin resistance, accumulation of triglycerides, marked increase in formation of small LDL particles, and delayed postprandial (after-eating) clearance of the lipoprotein byproducts of meals, all of which leads to diabetes, hypertension, and atherosclerosis.

I think we can all agree that replacing wheat with jelly beans and ice cream is not a good solution. And, no, we shouldn't have drunken binges, wife beating, smoking or bourbon to excess. So why does the "gluten-free" community advocate replacing wheat with products made with:

rice starch, tapioca starch, potato starch, and cornstarch?

These powdered starches are among the few foods that increase blood sugar (and thereby provoke glycation and insulin) higher than even the amylopectin A of wheat! For instance, two slices of whole wheat bread typically increase blood sugar in a slender, non-diabetic person to around 170 mg/dl. Two slices of gluten-free, multigrain bread will increase blood sugar typically to 180-190 mg/dl.

The fatal flaw in thinking surrounding gluten-free junk carbohydrates is this: If a food lacks some undesirable ingredient, then it must be good. This is the same fatally flawed thinking that led people to believe, for instance, that Snack Well low-fat cookies were healthy: because they lacked fat. Or processed foods made with hydrogenated oils were healthy because they lacked saturated fat.

So gluten-free foods made with junk carbohydrates are good because they lack gluten? No. Gluten-free foods made with rice starch, tapioca starch, potato starch, and cornstarch are destructive foods that NOBODY should be eating.

This is why the recipes for muffins, cupcakes, cookies, etc. in this blog, the Track Your Plaque website, and the Track Your Plaque Cookbook are wheat- and gluten-free and free of gluten-free junk carbohydrates. And put that bottle of Jim Beam down!

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

28. January 2011 William Davis (22)

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

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

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

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

The world of intermediate carbohydrates

28. January 2011 William Davis (0)

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

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

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

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

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

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

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

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

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

Heroin, Oxycontin, and a whole wheat bagel

25. January 2011 William Davis (27)

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

Hello Dr. Davis,

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

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

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

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

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

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

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

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

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

The five most powerful heart disease prevention strategies

24. January 2011 William Davis (39)

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

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

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

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

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

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

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

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

Topping up your vitamin D tank

22. January 2011 William Davis (17)

Now that my vitamin D replacement experience dates back nearly 5 years, I've been witnessing an unusual phenomenon:

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

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

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

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

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

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

Thirteen catheterizations later

21. January 2011 William Davis (16)

When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

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

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

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

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

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

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

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

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

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

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

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

High blood pressure vanquished

19. January 2011 William Davis (28)

Heart Scan Blog reader, Eric, related his blood pressure success story to me:

I'm 34 and have been battling chronic hypertension (systolic 150-200, depending on my anxiety levels) even with multiple prescriptions for over a decade now. I've seen four different cardiologists, all stumped as to what is causing my hypertension. First, they suspected coarctation of my aorta [a constriction in the aorta], but an angiogram determined blood pressure readings were the same on both sides of the narrowing.

The second angiogram performed last year to determine if my coarct had worsened determined that it had not, but that my aorta had calcium build up. The cardiologist was stumped because he told me he hasn't seen calcium in a patient so young. Needless to say, this scared me to death, with my wife being pregnant with our first child. I asked if it could be reversed and he didn't know so he sent me to get a Berkeley lab.

The Berkeley came back with LDL 91, HDL 41, Triglycerides 73, CRP 4.1, vit D 26. The doctors weren't very knowledgeable about explaining to me what these meant and how I could correct the low vit D and high CRP. They told me to follow the low-fat diet recommended by Berkeley. Well I've already tried the DASH diet and didn't like how I felt or my energy levels, so I didn't transition.

I was at a loss until I encountered your blog and it was truly a gift. It was a refreshing feeling to meet a knowledgeable Dr. who knew what I was going through and seems to truly care about reversing calcium in the heart (something I never got from my any of my cardiologists). With your blog I have an appointment to get a heart scan here in CO and take that number along with my Berkeley results and join Track Your Plaque.

For the past 2 weeks I've been following your advice by taking a D3+K2 supplement with Omega3 Fish oil and avoiding all grain, wheat, sugar and I'm already down 4lbs to 223.5lbs at 6'5" tall and my blood pressure readings have been 128/54 and 129/60 the past 2 days! With your help I may not have the dark future my father had: dead at 48 with a massive heart attack.

Stay on the look out because I look forward to telling you how I'm one of your top calcium losers!

Eric, Colorado

Conventional medical care fails at so many levels for so many people. While Eric's doctors were busy contemplating the next angiogram, they were neglecting several crucial aspects of his health.

It's really not that tough. But it can mean doing the opposite of what conventional "wisdom" tell us.

DHEA and Lp(a)

16. January 2011 William Davis (25)

DHEA supplementation is among my favorite ways to deal with the often-difficult lipoprotein(a), Lp(a).

DHEA is a testosterone-like adrenal hormone that declines with age, such that a typical 70-year old has blood levels around 10% that of a youthful person. DHEA is responsible for physical vigor, strength, libido, and stamina. It also keeps a lid on Lp(a).

While the effect is modest, DHEA is among the most consistent for obtaining reductions in Lp(a). A typical response would be a drop in Lp(a) from 200 nmol/L to 180 nmol/L, or 50 mg/dl to 42 mg/dl--not big responses, but very consistent responses. While there are plenty of non-responders to, say, testosterone (males), DHEA somehow escapes this inconsistency.

Rarely will DHEA be sufficient as a sole treatment for increased Lp(a), however. It is more helpful as an adjunct, e.g., to high-dose fish oil (now our number one strategy for Lp(a) control in the Track Your Plaque program), or niacin.

Because the "usual" 50 mg dose makes a lot of people bossy and aggressive, I now advise people to start with 10 mg. We then increase gradually over time to higher doses, provided the edginess and bossiness don't creep out.

The data documenting the Lp(a)-reducing effect of DHEA are limited, such as this University of Pennsylvania study, but in my real life experience in over 300 people with Lp(a), I can tell you it works.

And don't be scared by the horror stories of 10+ years ago when DHEA was thought to be a "fountain of youth," prompting some to take megadose DHEA of 1000-3000 mg per day. Like any hormone taken in supraphysiologic doses, weird stuff happens. In the case of DHEA, people become hyperaggressive, women grow mustaches and develop deep voices. DHEA doses used for Lp(a) are physiologic doses within the range ordinarily experienced by youthful humans.

No more cookies

15. January 2011 William Davis (13)

Jeanne enjoyed her Christmas holidays. She especially liked sharing the cookies she made for her grandchildren, sneaking 2 or 3 every day over a couple of weeks. On top of this, she enjoyed the Christmas candy, egg nog, leftover stuffing and cranberry sauce, topped off with a night of nutritional debauchery on New Year's Eve.

Lipid panel in October:

Total cholesterol 146 mg/dl
LDL cholesterol 72 mg/dl
HDL cholesterol 64 mg/dl
Triglycerides 49 mg/dl

Lipid panel in early January:

Total cholesterol 229 mg/dl
LDL cholesterol 141 mg/dl
HDL cholesterol 59 mg/dl
Triglycerides 147 mg/dl

I call the holidays The Annual Wheat and Sugar Frenzy. It's the carbohydrates, especially those from products made of wheat and sucrose, that caused the marked shifts in Jeanne's lipid patterns. Let's take each parameter apart:

--Triglycerides go up due to de novo lipogenesis, liver conversion of carbohydrates into triglycerides. Triglycerides enter the bloodstream as VLDL particles which, in turn, interact with LDL and HDL.

--LDL goes up because carbohydrate exposure increases VLDL, followed by conversion to LDL. The triglyceride-rich LDL created is converted to small LDL particles. Had we measured small LDL changes in Jeanne, we likely would have measured something like an increase (by NMR) from 800 nmol/L to 1600 nmol/L, a carbohydrate effect.

--The increased VLDL also makes HDL triglyceride-rich, cause more rapid degradation of HDL particles. (It also makes them smaller, like LDL.) Given sufficient time (a few more months), HDL would drop into the 40's.

--Total cholesterol changes reflect the composite of the above numbers. (Total cholesterol = LDL cholesterol + HDL cholesterol + Trig/5) (Note that, as HDL drops, so will total cholesterol; that's why this value is worthless and should be ignored.)

So don't be surprised by the above distortions after a period of carbohydrate indulgence. Although your unwitting primary care doc will see such changes as opportunity for Lipitor, it is nothing more than the cascade of effects from a carbohydrate-driven distortion of lipoproteins.

How to become diabetic in 5 easy steps

14. January 2011 William Davis (35)

If you would like to become diabetic in as short a time as possible, or if you have someone you don't like--ex-spouse, nasty neighbor, cranky mother-in-law--whose health you'd like to booby trap, then here's an easy-to-follow 5-step plan to make you or your target diabetic.

1) Cut your fat and eat healthy, whole grains--Yes, reduce satiety-inducing foods and replace the calories with appetite-increasing foods, such as whole grain bread, that skyrocket blood sugar higher than a candy bar.

2) Consume one or more servings of juice or soda per day--The fructose from the sucrose or high-fructose corn syrup will grow visceral fat and cultivate resistance to insulin.

3) Follow the Institute of Medicine's advice on vitamin D--Take no more than 600 units vitamin D per day. This will allow abnormal levels of insulin resistance to persist, driving up blood sugar, grow visceral fat, and allow abnormal inflammatory phenomena to persist.

4) Have a bowl of oatmeal or oat cereal every morning--Because oat products skyrocket blood sugar, the repeated high sugars will damage the pancreatic beta cells ("glucose toxicity"), eventually impairing pancreatic insulin production. (Entice your target even further: "Would you like a little honey with your oatmeal?") To make your diabetes-creating breakfast concoction even more effective, make the oatmeal using bottled water. Many popular bottled waters, like Coca Cola's Dasani or Pepsi's Aquafina, are filtered waters. This means they are devoid of magnesium, a mineral important for regulating insulin responses.

5) Take a diuretic (like hydrochlorothiazide, or HCTZ) or beta blocker (like metoprolol or atenolol) for blood pressure--Likelihood of diabetes increases 30% with these common blood pressure agents.

There you have it! Perhaps we should assemble a convenient do-it-yourself-at-home diabetes kit to help, complete with several servings of whole grain bread, a big bottle of cranberry juice, some 600 unit vitamin D tablets, a container of Irish oatmeal, and some nice bottled water.

Heart disease reversal is getting easier and easier

28. April 2006 William Davis (0)

I've recently observed that more and more of our patients on the Track Your Plaque program seem to be stopping or reducing their heart scan scores. And they're doing it faster, in less time, and with larger drops in score.

I'm not entirely sure why the sudden surge in success. However, I do wonder if adding therapeutic levels of vitamin D--at least in our generally sun-deprived Wisconsin participants--is responsible. However, we've also gotten a lot smarter on how to correct the parameters that seems to have outsized effects on plaque growth, especially small LDL.

Yesterday alone, we had two people we added to our list of successes. One, an attorney, stopped his score in one year, with no change (compared to the expected increase of 30%). Another, a woman from the northeast, dropped her score 10% in one year. Her story is remarkable for beginning at a score >1000. In general, the higher your starting score, the longer it takes to stop or reduce it.

These are just two examples. It seems to be happening at an accelerating pace.

I can only hope that our surge in success (not 100%--yet!) will continue. But, every week, we're adding more and more people to our list of success stories.

A used car lot on every street corner

28. April 2006 William Davis (0)

Imagine that, every day, a parade of used-car salesmen knock on your front door to sell you a special "deal". Day in, day out they knock, expecting you to hear about their offers openly.

Is there any doubt about their intentions or motives? Of course not. They're just trying to profit from selling you a car.

That's how it is in a medical office nowadays. Drug representatives, 5, 6, or more each and every day, promoting drugs. Except that the profits from drugs are far greater than a used automobile, and there's a third party involved in the transaction: you.

Today, a pushy representative came to my office. My staff and I tried to tell him that I was not interested in speaking to him. But he proved such a nuisance that I finally came out to tell him that I objected to the idea of drug reps just hanging around trying to hawk their wares.

He blurted, "Doctor, do you have patients with angina? Our new drug, ranolazine, is perfect. Forget about nitroglycerin, beta blockers, and all that. Here's the latest study proving it's better." He tried to shove a reprint of the study at me.

Getting to the bottom line, I asked, "What does it cost the patient?"

"Well, the co-pay is between $40 and $60. We're not yet well covered by insurance, so it'll cost patients around $200 a month."

Need I say more? Here's a drug that does little more than help relieve anginal chest pains. It doesn't reverse coronary plaque. It won't avoid heart attack, death, or procedures. It just modestly cuts back on the frequency of chest pain. And all for the cost of a single heart scan--a heart scan that could have prevented the entire cascade of symptoms/procedures/medication/hospitalization etc.

Hospitals, drug companies, medical device manufacturers. They're all businesses that thrive on your doctor's failure to detect and control your coronary plaque. Sometimes, even your doctor is part of this conspiracy to squeeze dollars out of human disease. Don't fall for it.

Heart disease reversal at age 77

28. April 2006 William Davis (0)

I met Agnes 18 months ago after she underwent a heart scan that revealed a scary score of over 1100. Although in her mid-70s, this was still a very high score. (Recall that a score this high carries a risk for heart attack and death of 25% per year.) Poor Agnes was a wreck over this unexpected result. "I can't sleep, I can't stop thinking about it!"

She'd undergone the scan because her 44-year old son had a heart scan score of 2200! Unfortunately, he ended up with a bypass operation for very severe disease.

Despite having been seeing a cardiologist in Boston for the last 8 years for a murmur, we uncovered multiple hidden lipoprotein patterns, many of which she shared with her son. Her most notable abnormalities were a low HDL and small LDL. Nearly 100% of all LDL particles were, in fact, small. This pattern also caused her LDL cholesterol to be underestimated by over 40%.

18 months on the Track Your Plaque program and Agnes came into town to get a repeat scan. Her score was 10.2% lower. She'd learned to live with the idea that she had hidden heart disease missed by her doctor and cardiologist for many years. But knowledge of the substantial reversal she'd achieved in the 18 months on the program gave Agnes tremendous peace of mind.

Agnes left the office with a big smile.

If you need a reason to quit smoking...

26. April 2006 William Davis (0)

If you've read Track Your Plaque, you already know my feelings about smoking and coronary plaque. Smoke, and you will lose the battle for control over coronary plaque growth--it will grow and grow until catastrophe strikes.

Nonetheless, this is not sufficiently motivating for some people.

If you need more motivation to quit smoking, just take a look at your heart scan sometime, accompanied by either one of the doctors or technicians at the scan center you choose. After you've had an opportunity to look at your coronary arteries, take a look at the lungs. The heart is in the middle and the lungs are the two large black areas on either side of the heart. (They're not really black; that's just the way the images are color-coded.)

Smokers will see large cavities in their lungs--literally, half-inch to one-inch wide holes that contain only air. Many of them. These represent remnants of lung tissue, digested away and now useless from the damage incurred through smoking.

Non-smokers should see uniform lung tissue without such cavities.

What surprised me early on in my heart scan experience was how little smoking exposure was required to generate these cavities. A 40-year old, for instance, who smoked a half-pack per day for 10 years would have them. Heavier smokers, of course, showed far more extensive cavities.

Officially, these cavities are called "emphysematous blebs", meaning the scars of the lung disease, emphysema.

When I've pointed out these cavities or emphysematous blebs to patients, 9 out of 10 times they immediately become non-smokers. Commonly, they'd exclaim, "I had no idea I was really damaging my lungs!" Most admitted that they were awaiting some bona fide evidence that they were truly doing some harm to their bodies. Well, that's it.

Give it a try if you're struggling.

Vitamin D for winter blues?

25. April 2006 William Davis (0)

Winter is now over and spring is in the air, even in Wisconsin.

In this part of the country, winter blues are commonplace. Sometimes called Seasonal Affective Disorder (SAD) when it's severe enough to cause functional impairment, feelings of fatigue, lack of motivation, or the blues are very frequent when days are short and sunlight is in short supply.

I've been seeing many people in the last several weeks who were advised to add vitamin D to their program last fall. Christopher's experience was typical.

"You know, since you told me to take vitamin D, I didn't get sad and tired like I do every winter. This is the first time I can remember that happening. I didn't sleep as much and I didn't get that feeling of always being overwhelmed."

I've felt it myself this past winter. I think there's some real truth to this effect.

Dr. Bruce Hollis has published a small experience in treating people with SAD with vitamin D and showed measurable improvement in depression. (One recent study in older women failed to show any effect, however, when small doses of vitamin D of 800 units were administered. In my experience, this dose doesn't even come close to normalizing blood vitamin D levels.)

The best source for in-depth information on vitamin D is Dr. John Cannell's website, www.vitaminDcouncil.com. If you've read Dr. Cannell's discussion on the Track Your Plaque website, you know that he is an articulate spokesman for the benefits of vitamin D replacement. He also persuasively argues that vitamin D deficiency is rampant in northern climates and in people who don't get frequent sun exposure. Interestingly, we now have two studies of populations in Florida and one in Hawaii, both of which showed substantial percentages of people even in these tropical climates to be deficient in vitamin D (around 50% in Hawaii and 30% in Florida).

The dose we've used with much success is 2000 units per day in females, 3000 units per day in males. This yields normal blood levels of around 50 ng/dl in around 80-90% of people. Occasional people will require more, some less. The best way to do it is to check a baseline blood level and a level on therapy to determine the adequacy of your dose.

Dr. Cannell will tell you that it's very important to have your doctor check the right test: 25-OH-vitamin D3, not 1,25-diOH-vitamin D3. These are two very different tests of two different compounds.

In the Track Your Plaque program, we use vitamin D to reduce pre-diabetic tendencies, reduce blood pressure (vitamin D is an inhibitor of the pressure-raising hormone renin), shut down inflammation, and gain better control over coronary plaque (mechanism uncertain). In the process, you will sharply reduce risk of osteoporosis, colon and prostate cancer.

And maybe you'll be brighter when the winter blues come around again.

$4 per gallon gas is good for your health!

24. April 2006 William Davis (0)

Gasoline is now approaching $4 per gallon in some parts of the U.S. But there's a silver lining in this dark cloud. In fact, I see this as a positive for your health.

How can higher gas prices possbily be good for health?

Imagine this trend continues: Fuel prices climb higher and higher. Driving your car will become increasingly more costly. What will be the fall-out?

Well, there will be a number of implications. But among the developments will be a broad impetus towards rejecting fuel-based sources of transportation. This may come as a shock to you, but humans legs were meant for walking!

Remember way back when, Mom would say "We need some milk"? In 1953, you wouldn't get in your car and zip to and from the supermarket. Instead, you would walk a quarter-mile, half-mile or more to the store. And you would carry your bags back. You might walk a mile or two to school and back. In 2006, this seems incomprehensible.

Higher fuel prices will prompt a gradual return to 1953--As transportation costs climb, your town may try and make it easier to walk as an alternative means of getting places.
Imagine that it was easy to walk three blocks to the grocery store, produce stand, work or school, walk along pleasant paths on the weekend, stroll to the home of friends. Drive or walk? Leave the car in the garage and save you and your family hundreds of dollars a month in gas bills.

In a few years, given the current fuel cost trends, there won't be a choice. But it will be in your favor for health.

Another Ornish casualty

23. April 2006 William Davis (0)

Barry's lipoproteins were nearly all corrected to perfection: LDL 64 mg, HDL 57 mg, triglycerides 45 mg. He was approaching the Track Your Plaque goal of 60/60/60, the levels we find tip the scales heavily in your favor for achieving plaque reversal.

But one problem still prominently persisted: small LDL. Of Barry's 64 mg of total LSL, 90% of his LDL were small.

Barry was already on niacin (Slo-Niacin; Upsher Smith)1000 mg per day and fish oil, 4000 mg per day, both of which contribute to correction of this pattern. He had added occasional raw almonds and oat bran to his daily habits, both of which also help suppress small LDL. "I thought you told me that small LDL should go away if I did all this!" he lamented in frustration.

We probed Barry's diet choices more closely. "I eat really healthy foods, just like an Ornish program." Uh oh.

"What do you mean?" I asked.

"For breakfast, I have two slices of whole wheat toast--no butter or margarine, of course! I'll have Shredded Wheat with skim milk. That's it. My typical lunch is low-fat turkey--no mayonnaise!--on whole wheat. I'll add some low-fat whole wheat crackers or pretzels. That's pretty much my habit."

"How about dinner?"

"Dinner varies a lot. I'll usually have a low-fat meat like chicken or turkey, never beef, a vegetable, and a potato. I love rolls but I try to make them whole wheat. I don't use gravy. I love ice cream, so I've been having low-fat frozen yogurt instead. I guess that's about it."

Barry had indeed been counseled on how we approach nutrition. We, of course, do not endorse the low-fat approach of the Ornish program. Low saturated and hydrogenated fat, yes, but not the super-strict low-fat, "all fat is bad" approach of Dr. Dean Ornish.

Barry's diet is typical of someone on a low-fat restriction. When I asked him why he was eating this way, he admitted that he'd seen Dr. Ornish on a TV program in which he persuasively proclaimed that he reversed heart disease in his patients over the past nearly 20 years using this low-fat approach.

That explained it. Barry's nearly pure carbohydrate diet was triggering high blood sugar responses after meals, causing his insulin to skyrocket and magnifying the small LDL pattern.

I advised Barry to dramatically reduce his carbohydates like breads, pretzels, low-fat yogurt, crackers, etc. Instead, he could increase his lean proteins like eggs, egg whites, Egg Beaters, raw nuts and seeds, low-fat (yes, low-fat!) dairy products like yogurt and cottage cheese (both high protein), and healthy oils.

I've seen this happen with many people over the years: A severe low-fat restriction becomes a high-carbohydate diet. It's not uncommon for many people to have more than 70% of calories from carbohydrates on these programs.

The low-fat approach worked in the era of high-fat diets in the 1980s. In 2006, where convenience foods made with carbohydrates, especially wheat, predominate and pack 80% of supermarket shelves, low-fat is now a distorted nutritional mistake that leads to problems like Barry's uncontrolled small LDL, and often pre-diabetic or overt diabetes.

Should you take Plavix?

22. April 2006 William Davis (2)

A question I get fairly frequently nowadays is, "Should I take Plavix?"

For the few of you who've managed to miss the mass advertising campaign for this drug on TV, USA Today, etc., Plavix is a platelet-blocking drug, known chemically as clopidogrel, that "thins" the blood and helps prevent blood clot formation in coronary arteries and carotid arteries, thus potentially reducing heart attack and stroke risk.

What if you have a heart scan score of, say, 450--should you take Plavix?

In general, no. First of all, aspirin and Plavix (generally taken together, since the effect of Plavix is incremental to that of aspirin) only block blood clot formation. They have no effect whatsoever on the rate of plaque growth. Aspirin and Plavix will neither slow it or increase it.

What they do is when a plaque ruptures like a little volcano and exposes its internal contents (inflammatory cells, fat, etc.--like a raw wound), a blood clot forms on top of the ruptured surface. If the clot is big enough, it can occlude the vessel and causes heart attack. Or, if it's a carotid artery, debris from the clot can break off and find its way headward to the artery controlling your speech or memory center. Aspirin and Plavix simply help inhibit clot formation once a plaque ruptures. That's it.

Interestingly, if you view any of Sanofi Aventis' commercials for Plavix, you'd think they came up with a cure for heart disease. It ain't true.

When is Plavix helpful? It's clearly an advantage after someone receives a coronary stent, drug-coated or uncoated;, after coronary bypass, particularly if certain metal punch devices are used to create the grafts in the aorta; and during and after heart attack. These are all situations in which blood clot formation is a forceful process. Blocking it helps.

In general, in asymptomatic people with positive heart scan scores at any level, we do not recommend taking Plavix. The Plavix people are extremely aggressive pushing their drug (hang around any medical office and see!) and, I believe, have gone overboard in promoting its benefits. Rarely, in someone with a very high heart scan score, say 2000 or more, we'll use Plavix for a period of a few months until lipids/lipoproteins and other risk measures are addressed, just as an added safety measure. But, in general, the great majority of people with some heart scan score or another do not receive it and I don't believe that they should.

As always, look beyond the marketing. The purpose of marketing is to increase profits, not to educate.

Dr. Ornish goofed

21. April 2006 William Davis (1)

"I don't think I need the Track Your Plaque program. I've been doing the Ornish program, so I think that my plaque has already regressed."

So proclaimed Bruce, a recent patient I saw in consultation. Having suffered a heart attack three years earlier, he was thoroughly convinced that he was now cured following the Ornish program.

Indeed, back in the 1980s, many of us existed on greasy, high-fat diets of cheeseburgers, French fries, fried chicken, plenty of butter or margarine, mayonnaise, and the like.

Along came Dr. Dean Ornish, who wrote a book called "Dr. Dean Ornish's Program for Reversing Heart Disease: The Only System Scientifically Proven to Reverse Heart Disease Without Drugs or Surgery". This book struck a chord during this era and has been a hot-seller ever since it was published.

Does it work? In my experience, no, it does not.

Dr. Ornish claimed that sharply curtailing fat intake reverses heart disease. Closer to the truth is that, in people who start with high fat intakes, a low-fat restriction is indeed an improvement. This will lead to a modest improvement in blood flow in the coronary arteries due to a phenomenon called "endothelial dysfunction." This means that arteries will dilate modestly when specific changes are made. Thus, you will see minimal improvements in the measures he used (stress testing with nuclear imaging.)

What it does not mean is that plaque has regressed, certainly not "reversed".

In fact, our experience (over 10 years ago, when we first used the Ornish approach) was that the majaority of people did worse on this low-fat program: HDL dropped, triglycerides increased, blood sugar increased, inflammatory measures like C-reactive protein increased. Some people even magnified diabetic or pre-diabetic patterns.

It's almost certain that Bruce has not reversed his coronary plaque. In fact, I would bet that his plaque has grown substantially. Bruce started three years earlier from a diet high in unhealthy fats. If the expected rate of coronary plaque growth is 30% per year, perhaps he slowed it--to 20% or so. Since he didn't have a heart scan score at the time of his heart attack, we'll never know if he truly did reduce the quantity of coronary plaque he had.

But when I met him on his Ornish program, Bruce showed disturbing patterns that included an HDL cholesterol of 38 mg, 70% of all LDL particles were small, triglycerides measured 209 mg, and C-reactive protein was high at 2.8 mg/l. In other words, Bruce's plaque causes were far from corrected. Perhaps they were worse.

The Ornish program, despite it's ambitious claims, has outlived its usefulness. In 2006, it is an antiquated relic of a time past when lifestyle habits and technology were different.

Warning: This product may contain wheat!

20. April 2006 William Davis (0)

Jerry experienced a peculiar sensation in his chest one evening while watching TV with his wife and kids. He squirmed in his chair and experienced a little breathelessness. But he kept it to himself and didn't say anything to his wife.

Fortunately, the feeling passed. But it concerned Jerry enough that he called a local heart scan center and scheduled a CT heart scan.* Minutes later, Jerry had a heart scan score of 112. At 46 years old, this placed him in the 90th percentile compared to other men in his age group.

Jerry came to my office for consultation. Among the first steps we took was to perform lipoprotein testing. Jerry showed striking abnormalities that included an HDL cholesterol of 38 mg, triglycerides of 210 mg, an unimpressive LDL of 133 mg but comprised of 99% small LDL, and excessive IDL (meaning that he was unable to clear dietary fats after eating).

At 5 feet 10 inches, Jerry weighed 190 lbs. He showed a slight excess bulge at the tummy, but hardly obese.

Jerry's history was remarkable, however, for the amount of carbohydrates he ate. "I'm addicted to bread. I love it! If I smell a loaf of fresh baked bread, I sometimes eat the whole loaf!"

Jerry also admitted to over-indulging in bagels (whole wheat), pretzels, low-fat snack chips, Raisin Bran cereal, Cheerios, and noodles. In fact, many days he'd have 5 or 6 servings of any of these foods. He also complained of an extraordinary amount of bowel gas and cramping. "Sometimes, I'm afraid to go to a group function. I might embarass myself."

I suggested an experiment: For a 4 week period, completely eliminate wheat-containing products--breads, pretzels, breakfast cereals, pasta, etc. In their place, increase intake of protein foods like eggs, raw almonds and walnuts, low-fat yogurt, cottage cheese, chicken, fish, and use healthy oils (olive, canola, grapeseed, flaxseed) more liberally.

Just four weeks later, Jerry came to the office a new man: 8 lbs lighter, brighter, with bursts of energy he hadn't had in years. And no gas!

Lesson: Wheat-based carbohydrates can be the culprit behind many lipoprotein patterns, especially low HDL, high triglycerides, small LDL, and others. Wheat can also be responsible for a myriad of abdominal symptoms, even joint pains and rashes. In its most extreme form, it's called "celiac disease". But experiences like Jerry's are quite common--not as obvious and dramatic as full-blown celliac disease, but smouldering and destructive, nonetheless.

Track Your Plaque expert, Dr. Loren Cordain of Colorado State University, tells us that, in his reconstruction of the history of human illness, there was an extraodinary surge in disease just about the time when humans began cultivating wheat around 8000 B.C. (Track Your Plaque members: Read Dr. Cordain's fascinating interview at http://www.cureality.com/library/fl_04-005cordaininterview.asp.)

Do you need to eliminate wheat products entirely from your diet? It's something to think about, particularly if you share any of the difficulties that Jerry had.

*In general, I do not recommend heart scanning as a self-prescribed tool for chest pain or other symptoms. Symptoms should always be discussed with your doctor.
