The manufacturers of krill oil claim that the phospholipid form of omega-3 fatty acids, EPA and DHA, enhance their absorption. There are indeed some data to that effect:

Here are some representative krill oil preparations available on the market:

MegaRed Krill Oil:
EPA 50 mg
DHA 24 mg
Total omega-3s (EPA + DHA + other forms) 90 mg
Price: $28.99 for 60 softgels

Source Naturals (a fine company otherwise, by the way):

EPA 150 mg
DHA 90 mg
Total omega-3 fatty acids 300 mg
Price: $24.99 for 60 softgels

Alright, let's do some simple math:

Average volume of blood in the human body (all components): 5000 cc
Percentage of red blood cells (RBCs) by volume: 45%
Total volume RBCs: 2250 cc
Percentage of total volume RBCs occupied by fatty acids:

In the conventional practice of early heart disease prevention, cholesterol testing takes center stage. Rarely does it go any further, aside from questions about family history and obvious sources of modifiable risk such as smoking and sedentary lifestyle.

So standard practice is to usually look at your LDL cholesterol, the value that is calculated, not measured, then--almost without fail--prescribe a statin drug. While there are indeed useful values in the standard cholesterol panel--HDL cholesterol and triglycerides--they are typically ignored or prompt no specific action.

But a genuine effort at heart disease prevention should go farther than an assessment of calculated LDL cholesterol, as there are many ways that humans develop coronary atherosclerosis. Among the tests to consider in order to craft a truly effect heart disease prevention program are:

--Lipoprotein testing--Rather than using the amount of cholesterol in the various fractions of blood as a crude surrogate for lipoproteins in the bloodstream, why not measure lipoproteins themselves? These techniques have been around for over 20 years, but are simply not part of standard practice.

Lipoprotein testing especially allows you to understand what proportion of LDL particles are the truly unhealthy small LDL particles (that are oxidation- and glycation-prone). It also identifies whether or not you have lipoprotein(a), the heritable factor that confers superior survival capacity in a wild environment ("The Perfect Carnivore"), but makes the holder of this genetic pattern the least tolerant to the modern diet dominated by grains and sugars, devoid of fat and organ meats.

--25-hydroxy vitamin D--The data documenting the health power of vitamin D restoration continue to grow, with benefits on blood sugar and insulin, blood pressure, bone density, protection from winter "blues" (seasonal affective disorder), decrease in falls and fractures, decrease in cancer, decrease in cardiovascular events. I aim to keep 25-hydroxy vitamin D at a level of 60 to 70 ng/ml. This generally requires 4000-8000 units per day in gelcap form, at least for the first 3 or so years, after which there is a decrease in need. Daily supplementation is better than weekly, monthly, or other less-frequent regimens. The D3 (cholecalciferol) form is superior to the non-human D2 (ergocalciferol) form.

--Hemoglobin A1c (HbA1c)--HbA1c represents glycated hemoglobin, i.e., hemoglobin molecules within red blood cells that are irreversibly modified by glucose, or blood sugar. It therefore provides an index of endogenous glycation of all proteins of the body: proteins in the lenses of the eyes that lead to cataracts; proteins in the cartilage of the knees and hips that lead to brittle cartilage and arthritis; proteins in kidney tissue leading to kidney dysfunction.

HbA1c provides an incredibly clear snapshot of health: It reflects the amount of glycation you have been exposed to over the past 90 or so days. We therefore aim for an ideal level: 5.0% or less, the amount of "ambient" glycation that occurs just with living life. We reject the notion that a HbA1c level of 6.0% is acceptable just because you don't "need" diabetes medication, the thinking that drives conventional medical practice.

--RBC Omega-3 Index--The average American consumes very little omega-3 fatty acids, EPA and DHA, such that a typical omega-3 RBC Index, i.e., the proportion of fatty acids in the red blood cell occupied by omega-3 fatty acids, is around 2-3%, a level associated with increased potential for sudden cardiac death (death!). Levels of 6% or greater are associated with reduced potential for sudden cardiac death; 10% or greater are associated with reduced other cardiovascular events.

Evidence therefore suggests that an RBC Omega-3 Index of 10% or greater is desirable, a level generally achieved by obtaining 3000-3600 mg EPA + DHA per day (more or less, depending on the form consumed, an issue for future discussion).

--Thyroid testing (TSH, free T3, free T4)--Even subtle degrees of thyroid dysfunction can double, triple, even quadruple cardiovascular risk. TSH values, for instance, within the previously presumed "normal" range, pose increased risk for cardiovascular death; a TSH level of 4.0 mIU, for instance, is associated with more than double the relative risk of a level of 1.0.

Sad fact: the endocrinology community, not keeping abreast of the concerning issues coming from the toxicological community regarding perchlorates, polyfluorooctanoic acid and other fluorinated hydrocarbons, polybrominated diphenyl ethers (PDBEs), and other thyroid-toxic compounds, tend to ignore these issues, while the public is increasingly exposed to the increased cardiovascular risk of even modest degrees of thyroid dysfunction. Don't commit the same crime of ignorance: Thyroid dysfunction in this age of endocrine disruption can be crucial to cardiovascular and overall health.

All in all, there are a number of common blood tests that are relevant--no, crucial--for achieving heart health. Last on the list: standard cholesterol testing.

Happy Thanksgiving 2012, everyone, from all the staff at Track Your Plaque!

Here’s a zesty version of traditional cranberry sauce, minus the sugar. The orange, cinnamon, and other spices, along with the crunch of walnuts, make this one of my favorite holiday side dishes.

There are 31.5 grams total “net” carbohydrates in this entire recipe, or 5.25 grams per serving (serves 6). To further reduce carbs, you can leave out the orange juice and, optionally, use more zest.

1 cup water
12 ounces fresh whole cranberries
Sweetener equivalent to 1 cup sugar (I used 6 tablespoons Truvía)
1 tablespoon orange zest + juice of half an orange
½ cup chopped walnuts
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
¼ teaspoon ground cloves

In small to medium saucepan, bring water to boil. Turn heat down and add cranberries. Cover and cook at low-heat for 10 minutes or until all cranberries have popped. Stir in sweetener. Remove from heat.

Stir in orange zest and juice, walnuts, cinnamon, nutmeg, and cloves.

Transfer mixture to bowl, cool, and serve.

Apple, cranberry, and cinnamon: the perfect combination of tastes and scents for winter holidays!

I took a bit of carbohydrate liberties with this recipe. The entire recipe yields a delicious cheesecake-like crumble with 59 “net” grams carbohydrates (total carbs – fiber); divided among 10 slices, that’s 5.9 grams net carbs per serving, a quantity most tolerate just fine. (To reduce carbohydrates, the molasses in the crumble is optional, reducing total carbohydrate by 11 grams.)

Other good choices for sweeteners include liquid stevia, stevia glycerite, powdered stevia (pure or inulin-based, not maltodextrin-based), Truvía, Swerve, and erythritol. And always taste your batter to test sweetness, since sweeteners vary in sweetness from brand to brand and your individual sensitivity to sweetness depends on how long you’ve been wheat-free. (The longer you’ve been wheat-free, the less sweetness you desire.)

Crust and crumble topping
3 cups almond meal
1 stick (8 tablespoons) butter, softened
1 cup xylitol (or other sweetener equivalent to 1 cup sugar)
1½ teaspoons ground cinnamon
1 tablespoon molasses
1½ teaspoons vanilla extract
Dash sea salt

Filling
16 ounces cream cheese, softened
2 large eggs
½ cup xylitol (or other sweetener equivalent to ½ cup sugar)
1 Granny Smith apple (or other variety)
1 teaspoon ground cinnamon
1 cup fresh cranberries

Preheat oven to 350° F.

In large bowl, combine almond meal, butter, sweetener, cinnamon, molasses, vanilla, and salt and mix.

Grease a 9½-inch tart or pie pan. Using approximately 1 cup of the almond meal mixture, form a thin bottom crust with your hands or spoon.

In another bowl, combine cream cheese, eggs, and sweetener and mix with spoon or mixer at low-speed. Pour into tart or pie pan.

Core apple and slice into very thin sections. Arrange in circles around the edge of the cream cheese mixture, working inwards. Distribute cranberries over top, then sprinkle cinnamon over entire mixture.

Gently layer remaining almond meal crumble evenly over top. Bake for 30 minutes or until topping lightly browned.

Biscuits and gravy: the ultimate comfort food . . . one you thought you’d never have again!

The familiar dish of breakfast and holiday meals is recreated here with a delicious gravy that you can pour over piping hot biscuits. Because it contains no wheat or other unhealthy thickeners like cornstarch made with “junk” carbohydrates, there should be no blood sugar or insulin problems with this dish, nor joint pain, edema, acid reflux, mind “fog,” or dandruff—life is good without wheat!

While the gravy is also dairy-free for those with dairy intolerances, the biscuits are not, as there are cheese and butter in the biscuits, both of which are optional, e.g., leave out the cheese and replace butter with coconut or other oil.

Makes 10 biscuits

Gravy:
2 tablespoons extra-virgin olive oil
1 pound loose sausage meat
2½ cups beef broth
¼ cup coconut flour
½ cup coconut milk (canned variety)
1 tablespoon onion powder
1 teaspoon garlic powder
½ teaspoon sea salt
Dash ground black pepper

Biscuits:
1 cup shredded cheddar (or other) cheese
2 cups almond meal/flour
¼ cup coconut flour
¾ teaspoon baking soda
½ teaspoon sea salt
2 large eggs
4 ounces butter, melted (or other oil, e.g., extra-light olive, coconut, walnut)

To make gravy:
In large skillet, heat oil over medium heat. Sauté sausage, breaking up as it browns. Cook until thoroughly cooked and no longer pink.

Turn heat up to medium to high and pour in beef broth. Heat just short of boiling, then turn down to low heat. Stir in coconut flour, little by little, over 3-5 minutes; stop adding when gravy obtains desired thickness. Pour in coconut milk and stir in well. Add onion powder, garlic powder, salt, and pepper and simmer over low heat for 5 minutes. Add additional salt and pepper to taste. Remove from heat and set aside.

To make biscuits:
Preheat oven to 325° F.

In food chopper or processor, pulse shredded cheese to finer, granular consistency.

Pour cheese into large bowl, then add almond meal, coconut flour, baking soda, and salt and mix thoroughly. Add the eggs and butter or oil and mix thoroughly to yield thick dough.

Spoon out dough into 10 or so ¾-inch thick mounds onto a parchment paper-lined baking pan. Bake for 20 minutes or until lightly browned and toothpick withdraws dry.

Ladle gravy onto biscuits just before serving.

People who carry the gene for lipoprotein(a), Lp(a), tend to be:

--Intelligent--The bell curve of IQ is shifted rightward by a substantial margin.
--Athletic--With unusual capacity for long-endurance effort, thus the many marathoners, triathletes, and long-distance bikers with Lp(a).
--Tolerant to dehydration
--Tolerant to starvation
--Resistant to tropical infections

In other words, people with Lp(a) have an evolutionary survival advantage. More than other people, they make clever, capable hunters who can run for hours to chase down prey, not requiring food or water, and less likely to succumb to the infections of the wild. In a primitive setting, people with Lp(a) are survivors. Evolution has likely served to select Lp(a) people for their superior survival characteristics.

But wait a minute: Isn't Lp(a) a risk for heart attack and stroke? Don't we call Lp(a) "the most aggressive known cause for heart disease and stroke that nobody gives a damn about"?

Yes. So what allows this evolutionary advantage for survival to become a survival disadvantage?

Carbohydrates, especially those from grains and sugars. Let me explain.

More so than other people, Lp(a) people express the small LDL pattern readily when they consume carbohydrates such as those from "healthy whole grains." Recall that the gene for Lp(a) is really the gene for apoprotein(a), the protein that, once produced by the liver and released into the bloodstream, binds to an available LDL particle to create the combination Lp(a) molecule. If the LDL particle component of Lp(a) is small, it confers greater atherogenicity (greater plaque-causing potential). Thus, carbohydrate consumption makes Lp(a) a more aggressive cause for atherosclerotic plaque. The situation can be made worse by exposure to vegetable oils, such as those from sunflower or corn, which increases production of apo(a).

Also, more than other people, Lp(a) people tend to show diabetic tendencies with consumption of carbohydrates. Eat "healthy whole grains," for instance, or if a marathoner carb-loads, he/she will show diabetic-range blood sugars. I have seen long-distance runners or triathletes, for instance, have a 6 ounce container of sugary yogurt and have blood sugars of 200 mg/dl or higher. The extreme exercise provides no protection from the diabetic potential.

Because carbohydrates are so destructive to the Lp(a) type, it means that people with this pattern do best by 1) absolutely minimizing exposure to carbohydrates and vegetable oils, ideally grain-free and sugar-free, and 2) rely on a diet rich in fats and proteins.

The perfect diet for the Lp(a) type? It would be a diet of feasting on the spoils of the hunt, devouring the wild boar captured and slaughtered and eating the snout, hindquarters, spleen, kidneys, heart, and bone marrow, then eating mushrooms, leaves, nuts, coconut, berries, small rodents, reptiles, fish, birds, and insects when the hunt is unproductive.

Capable hunter, survivor, consumer of muscle and organ meats: I call people with Lp(a) "The Perfect Carnivores."

The NPR Health Blog contacted me, as they were interested in learning more about health strategies and tools that are being used by individuals without their doctors. The Track Your Plaque website and program came up in their quest, as it is the only program available for self-empowerment in heart disease.

Several Track Your Plaque Members spoke up to add their insights. The full text of the article can be viewed here.

How's Your Cholesterol? The Crowd Wants To Know
Mainstream medicine isn't in favor of self-analysis, or seeking advice from non-professionals, of course. And anyone who does so is running a risk.

But there are folks who want to change the course of their heart health with a combination of professional and peer support. Some are bent on tackling the plaque that forms in arteries that can lead to heart disease. They gather online at Track Your Plaque, or "TYP" to the initiates.

"We test, test, test ... and basically experiment on ourselves and have through trial and error came up with the TYP program, which is tailored to the individual," Patrick Theut, a veteran of the site who tells Shots he has watched his plaque slow, stop and regress.

The site was created in 2004 by Bill Davis, a preventive cardiologist in Milwaukee, Wisc. Davis is also the author of Wheat Belly: Lose the Wheat, Lose the Weight and Find Your Path Back to Health, which argues that wheat is addictive and bad for most people's health. Davis recommends eliminating wheat from the diet to most new members of Track Your Plaque.

"The heart is one of the hardest things to self-manage but when you let people take the reins of control, you get far better results and far fewer catastrophes like heart attacks," Davis tells Shots.

Doctors typically give patients diagnosed with heart disease two options: take cholesterol-lowering statin drugs, or make lifestyle changes, like diet. It's usually far easier for both parties — the doctor and the patient — to go with the drugs than manage the much more difficult lifestyle changes, Davis says.

"Doctors say take the Lipitor, cut the fat and call me if you have chest pain," he explains. "But that's an awful way to manage care."

TYP has members submit their scores from heart CT scans, cholesterol values, lipoproteins and other heart health factors to a panel of doctors, nutritionists and exercise specialists. Then they receive advice in the form of an individualized plaque-control program. But the online forum, where users share their results with other members and exchange tips, is where most of the TYP action happens.

The community currently has about 2,400 members who pay $39.95 for a quarterly membership, or $89.75 for a yearly membership. Davis says all proceeds go towards maintaining the website.

Ilaine Upton is a 60-year-old bankruptcy lawyer from Fairfax, Va., and a TYP member. At a friend's suggestion, Upton decided to get a heart CT scan in July. Her score was higher than it should have been (22 instead of 0), so she decided to get her blood lipids and cholesterol tested, too, and sent a sample off to MyMedLabs.com.

She learned that her LDL particle count was over 2,000 ("crazy high," she says), and she posted her results on TYP. Davis advised her that a low-carb diet would reduce it, so she decided to try it.

Since July, she says she has had "excellent results" with the program, and her LDL counts are coming down.

"It would be nice to have a [personal] physician involved in this, but [my insurer] Blue Cross won't pay if you are not symptomatic, and I am trying to prevent becoming symptomatic," says Upton. "I feel very empowered by this knowledge and the ability to take better control of my health by getting feedback on the decisions I make."

This is about as decadent as it gets around here!

Here’s a recreation of an old-fashioned coffee cake, a version with a delicious chewy-crunchy streusel topping.

I’ve specified xylitol as the sweetener in the topping, as it is the most compatible sweetener for the streusel “crumb” effect and browning.

Variations are easy. For example, for an apple pecan coffee cake, add a layer of finely-chopped or sliced apples to the cake batter and topping.

Additional potential carbohydrate exposure comes from the garbanzo bean flour and molasses. However, distributed into 10 slices, each slice provides 7.2 grams “net” carbs (total carbs minus fiber), a perfectly tolerable amount. Be careful not to exceed two slices!

Yield 10 slices

Cake:
2½ cups almond flour
½ cup garbanzo bean flour
1 tablespoon ground cinnamon
1 teaspoon baking soda
Sweetener equivalent to ¾ cup sugar
Dash sea salt

3 eggs separated
3/8 teaspoon cream of tartar
1 tablespoon vanilla extract
4 ounces butter, melted
Juice of ½ lemon

Topping:
½ cup almond flour
¼ cup pecans, finely chopped
1 tablespoon ground cinnamon
½ cup xylitol
1 tablespoon molasses
6 ounces butter, cut into ½-inch widths, at room temperature

Preheat oven to 325º F. Grease bread pan.

In bowl, combine almond flour, garbanzo flour, cinnamon, baking soda, sweetener, salt, and mix.

In small bowl, whip egg whites and cream of tartar until stiff peaks form. At low speed, blend in egg yolks, vanilla, melted butter, and lemon juice.

Pour liquid mixture into almond mixture and mix thoroughly. Pour into microwave-safe bread pan and microwave on high for 3 minutes. Remove and set aside.

To make topping, combine almond flour, pecans, cinnamon, xylitol, and molasses in small bowl and mix. Mix in butter

Spread topping on cake. Bake for 20 minutes or until toothpick withdraws dry.

If you miss peanut butter and jelly sandwiches, you’re going to absolutely love these peanut butter and jelly macaroons!

Not everybody loves the taste or texture of coconut. This issue is solved by the first step: toasting shredded coconut, then reducing them down to a granular consistency. This yields a macaroon consistency without the dominant coconut taste, replaced instead with the flavors of PB & J.

I’ve specified liquid stevia as the sweetener, but this is easily replaced by your choice of sweetener. Note that, regardless of which sweetener used, they vary in sweetness from brand to brand and the quantity required to equal the ½ cup of sugar equivalent can vary. It always helps to taste your batter and adjust sweetness.

Also, I used Swerve in this recipe, the erythritol-inulin mix that enhances texture, but its use is optional.

As written, each macaroon contains just over 3 grams “net” carbohydrates (total carbs minus fiber), meaning you can have several before doing any damage!

Makes 24 macaroons

3 cups shredded unsweetened coconut
2 tablespoons vanilla extract
1 teaspoon almond extract
¼ cup coconut flour
¼ cup dried unsweetened cherries (or other unsweetened berries)
2 tablespoons coconut oil
¼ cup natural peanut butter, room temperature
2 egg whites
½ teaspoon liquid stevia or sweetener equivalent to ½ cup sugar
2 tablespoons Swerve

Preheat oven to 300° F.

In large bowl, combine coconut, vanilla and almond extracts, and mix.

Spread mixture on baking sheet and bake for 10 minutes, stirring occasionally, until very lightly browned. Be careful not to burn. Remove and cool. (Leave oven at 300° F.)

When cooled, using food chopper, food processor, or coffee grinder, pulse coconut mixture until coconut reduced to consistency of coffee grounds. Pour back into bowl. Stir in coconut flour.

Place cherries or other berries in food chopper, food processor, or coffee grinder and pulse until reduced to small granules or paste. Remove with spatula and add to coconut mixture. Set aside.

Place egg whites in bowl and whip until frothy and stiff peaks form.

In small microwave-safe bowl, combine coconut oil and peanut butter and microwave in 10-second increments until warm (not hot) liquid. Stir in egg whites, followed by stevia and Swerve, and blend thoroughly.

Dispense dough onto a parchment paper-lined baking sheet using a 1 ½-inch cookie scooper or spoons.

Bake for 15 minutes or until lightly browned.

Why would I say such a thing? Well, a number of reasons. People with lipoprotein(a), or Lp(a), are, with only occasional exceptions:

--Very intelligent. I know many people with this genetic pattern with IQs of 130, 140, even 160+.
--Good at math--This is true more for the male expression of the pattern, only occasionally female. It means that men with Lp(a) gravitate towards careers in math, accounting, financial analysis, physics, and engineering.
--Athletic--Many are marathon runners, triathletes, long-distance bicyclists, and other endurance athletes. I tell my patients that, if they want to meet other people with Lp(a), go to a triathlon.
--Poor at hydrating. People with Lp(a) have a defective thirst mechanism and often go for many hours without drinking water. This is why many Lp(a) people experience the pain of kidney stones: Prolonged and repeated dehydration causes crystals to form in the kidneys, leading to stone formation over time.
--Tolerant to dehydration--Related to the previous item, people with Lp(a) can go for extended periods without even thinking about water.
--Tolerant to periods of food deprivation or starvation--More so than other people, those with Lp(a) are uncommonly tolerant to days without food, as would occur in a wild setting.

In short, people with Lp(a) are intelligent, athletic, with many other favorable characteristics that provide a survival advantage . . . in a primitive world.

So when did Lp(a) become a problem? When an individual with Lp(a) is exposed to carbohydrates, especially those from grains. When an evolutionarily-advantaged Lp(a) individual is exposed to carbohydrates, more than other people they develop:

--Excess quantities of small LDL particles--Recall that Lp(a) is a two-part molecule. One part: an apo(a) made by the liver. 2nd part: an LDL particle. When the LDL particle within the Lp(a) molecule is small, its overall behavior is worse or more atherogenic (plaque-causing).
--Hyperglycemia/hyperinsulinemia--which then leads to diabetes. Unlike non-Lp(a) people, these phenomena can develop with far less visceral fat. A Lp(a) male, for instance, standing 5 ft 10 inches tall and weighing 150 pounds, can have as much insulin resistance/hyperglycemia as a non-Lp(a) male of similar height weighing 50+ pounds more.

Key to gaining control over Lp(a) is strict carbohydrate limitation. Another way to look at this is to say that Lp(a) people do best with unlimited fat and protein intake.

I took my family to a local all-you-can-eat Indian buffet. It was delicious.

I confined my food choices mostly to vegetables and soups. Within about 30 minutes, I started to get that odd buzz in my head that usually signals a high blood sugar.

When I got home, my fingerstick blood glucose: 173 mg/dl. Darn it! Must have been cornstarch or other sugars in the sauces.

I got on my supine stationary bike and pedaled for 40 minutes at a moderate pace while I played Modern Warfare on XBox. (A great way, by the way, to fit in some low- to moderate-intensity exercise while occupying your brain. My wife often has to yell at me to get off, it's so much fun.)

Blood glucose at the conclusion of exercise: 93 mg/dl-- a nice 80 mg/dl drop.

This is a useful strategy to use in a pinch when you've either been inadvertently exposed to more carbohydrate than you can tolerate, or if you'd like to blunt the adverse glucose effects of a bowl of ice cream or other carbohydrate indulgence.

Should we explore the idea of a "morning-after" pill, or actually a "meal-after" pill, a supplement pill or liquid that blunts or eliminates the blood glucose rise after a meal? I've considered such an idea, but have been fearful that people would start to use it habitually. Thoughts?

Heart Scan Blog reader, Roger, brought this New York Times article to my attention.

In an effort to develop a better experimental model for obesity than mice, scientists have turned to monkeys and other primates. The emerging observations are eerily reminiscent of what you and I witness just by going to the local grocery store or fast food outlet:

"'It wasn’t until we added those carbs that we got all those other changes, including those changes in body fat,' said Anthony G. Comuzzie, who helped create an obese baboon colony at the Southwest National Primate Research Center in San Antonio."

"Fat Albert, one of her monkeys who she said was at one time the world’s heaviest rhesus, at 70 pounds, ate “nothing but American Heart Association-recommended diet,” she said."

Yes, indeed: The American Heart Association diet makes monkeys fat. Extrapolate this a little higher on the evolutionary ladder and guess what?

This is one of the many reasons why, when I have a patient who is counseled by the hospital dietitian on the American Heart Association diet, I advise them to 1) ignore everything the dietitian told them, and then 2) follow the wheat-free, cornstarch-free, sugar-free, whole food diet I advocate.

Not unexpectedly, much of this primate research is not being devoted to just manipulating diet to achieve weight loss and health, but to develop new drugs to "treat" obesity.

Would you like a banana?

In a previous Heart Scan Blog post, I discussed how to make use of postprandial (after-meal) blood sugars to reduce triglycerides, reduce small LDL, increase HDL, reduce blood pressure and inflammatory measures, and accelerate weight loss.

In that post, I suggested checking blood glucose one hour after finishing a meal. However, this is a bit of an oversimplification. Let me explain.

A number of factors influence the magnitude of blood glucose rise after a meal:

--Quantity of carbohydrates
--Digestibility of carbohydrates--The amylopectin A of wheat, for example, is among the most digestible of all, increasing blood sugar higher and faster.
--Fat and protein, both of which blunt the glucose rise (though only modestly).
--Inclusion of foods that slow gastric emptying, such as vinegar and fibers.
--Body weight, age, recent exercise

Just to name a few. Even if 10 people are fed identical meals, each person will have a somewhat different blood glucose pattern.

So it can be helpful to not just assume that 60 minutes will be your peak, but to establish your individual peak. It will vary from meal-to-meal, day-to-day, but you can get a pretty good sense of blood glucose behavior by constructing your own postprandial glucose curve.

Say I have a breakfast of oatmeal: slow-cooked, stoneground oatmeal with skim milk, a few walnuts, blueberries. Blood glucose prior: 95 mg/dl. Blood glucose one-hour postprandial: 160 mg/dl.

Rather than taking a one-hour blood glucose, let's instead take it every 15 minutes after you finish eating your oatmeal:

In this instance, the glucose peak occurred at 90-minutes after eating. 90-minute postprandial checks may therefore better reflect postprandial glucose peaks for this theoretical individual.

I previously picked 60-minutes postprandial to approximate the peak. You have the option of going a step better by, at least one time, performing your own every-15-minute glucose check to establish your own curve.

Type 1 diabetes, also called "childhood" or "insulin-dependent" diabetes, is on the rise.

Type 2 diabetes, or "adult," diabetes, is also sharply escalating. But the causes for this are easy-to-identify: overconsumption of carbohydrates and resultant weight gain/obesity, inactivity, as well as genetic predisposition. A formerly rare disease is rapidly becoming the scourge of the century, expected to affect 1 in 3 adults within the next several decades.

Type 1 diabetes, on the other hand, generally occurs in young children, not uncommonly age 3 or 4. Type 1 diabetes also shares a genetic basis to some degree. But the genetic predisposition should be a constant. Obviously, lifestyle issues cannot be blamed in young children.
Then why would type 1 diabetes be on the rise?

For instance, this study by Vehik et al from the University of Colorado documents the approximate 3% per year increase in incidence in children with type 1 diabetes between 1978 and 2004:

(From Vehik 2007)

(For an excellent discussion of the increase in type 1 diabetes in the 20th century, see this review.)

This is no small matter. Just ask any parent of a child diagnosed with type 1 diabetes who, after recovering from hearing the devastating diagnosis, then has to stick her child's fingers to check glucose several times per day, mind carefully what he or she eats or doesn't eat, watch carefully for signs of life-threatening hypoglycemic episodes, not to mention worry about her child's long-term health. Type 1 diabetes is a life-changing diagnosis for both child and parents.

Various explanations have been offered to account for this disturbing trend. Some attribute it to the increase in breast feeding since 1980 (highly unlikely), exposure to some unidentified virus, or other exposures.

I'd like to offer another explanation: wheat.

Lest you accuse me of becoming obsessed with this issue, let me point out the four observations that lead me to even consider such an association:

1) Children diagnosed with celiac disease, i.e., the immune disease of wheat gluten exposure, have 10-fold greater likelihood of developing type 1 diabetes.

2) Children diagnosed with type 1 diabetes are 10-fold more likely to have abnormal levels of antibodies (e.g., transglutaminase antibodies) to wheat gluten.

3) Experimental models, such as in these mice genetically susceptible to type 1 diabetes, showed a reduction of type 1 diabetes from 64% to 15% with avoidance of wheat.

4) The increase in type 1 diabetes corresponds to the introduction of new strains of wheat that resulted from the extensive genetics research and hybridizations carried out on this plant in the 1960s. In particular, unique protein antigens (immune-provoking sequences) were introduced with the dwarf variant attributable to alterations in the "D" genome of modern Triticum aestivum.

Proving the point is tough: Would you enroll your newborn in a study of wheat-containing diet versus no wheat, then watch for 10 years to see which group develops more type 1 diabetes? It is a doable study, just a logistical nightmare. Perhaps the point will be settled as more and more people catch onto the fact that modern wheat--or this thing we are being sold called "wheat"--is a corrupt and destructive "foodstuff" and eliminate it from their lives and the lives of their young children from birth onwards. Then a comparison of wheat-consuming versus non-wheat-consuming populations could be made. But it will be many years before this crucial question is settled.

Yet again, however, the footprints in the sand seem to lead back to wheat as potentially underlying an incredible amount of human illness and suffering. Yes, the stuff our USDA puts at the bottom, widest part of the food pyramid.

Phytosterols, or just "sterols" to its friends and neighbors, are a group of cholesterol-like compounds that are abundant in the plant world. Lately, however, sterols have proliferated in the processed food supply, thanks to the observation that sterols reduce LDL cholesterol when ingested by humans.

This must mean that sterols are good for you.

Uh oh. Wait a minute: There is a rare disease called sitosterolemia in which there is unimpeded intestinal absorption of all sterols ingested through diet. They must have really low LDL cholesterols! Nope. They develop coronary disease--heart attacks, angina, etc.--in their late teens and 20s. In other words, if sterols gain access to your bloodstream, they are bad. Very bad.

Conventional thinking is that only a modest quantity of dietary sterols gain access to the bloodstream. But there are two potentially fatal flaws in this overly simplistic line of thinking:

1) What happens when you load up your diet with "heart healthy" sterols, such as those in "heart healthy" margarines, mayonnaise, and yogurt, effectively increasing sterol intake 10-fold?

2) What happens in people with the genetic pattern, apo E4, that is carried by 25% of the general population that permits much greater intestinal absorption of sterols?

My prediction: Despite the fact that sterols reduce LDL, they may, in certain genetically-susceptible people, such as those with apo E4, increase risk for heart disease: heart unhealthy.

Here are two studies that suggest that greater sterol absorption in people without sitosterolemia are at higher risk for heart disease:

Alterations in cholesterol absorption/synthesis markers characterize Framingham offspring study participants with CHD

Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study

As I suggested in a previous Heart Scan Blog post, a glucose meter is your best tool to:

1) Lose weight
2) Cure diabetes
3) Reduce or eliminate small LDL particles
4) Achieve anti-aging or age-slowing effects

But it means getting hold of a glucose meter and applying it in a very different way.

Diabetics typically check fasting morning glucose and again several times during the day to assess medication effects. But you and I can measure blood glucose to assess the immediate effects of food choices--two very different approaches.

The concept is simple: Check a blood glucose just prior to a food or meal of interest, then one hour after finishing.

Let's take two hypothetical breakfasts. First, oatmeal, a so-called "low-glycemic index" food. Slow-cooked, stone ground oatmeal with skim milk, a handful of walnuts, just a few blueberries.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 175 mg/dl

I made those numbers up, but this is a fairly typical response for many adults. (This is why "low-glycemic index" is an absurd notion.) This kind of response causes 1) glycation, the adverse effects of glucose modification of proteins that leads to cataracts, kidney disease, cartilage damage and arthritis, atherosclerosis, skin wrinkles, etc., 2) high insulin response that cascades into fat deposition, especially visceral fat ("wheat belly"), and 3) glucotoxicity, i.e., direct damage to the pancreas that can, over years, lead to diabetes.

Next day, let's try a breakfast of 3-egg omelet made with green peppers, sundried tomatoes, and olive oil.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 93 mg/dl

This is a meal of virtually zero-glycemic index. This kind of response triggers none of the effects experienced following the oatmeal. Repeated over time and you fail to trigger glycation, you stop provoking insulin, and visceral fat mobilizes rather than accumulates: you lose weight, particularly around the middle.

We therefore aim to keep the one-hour blood glucose 100 mg/dl or less. If you start with a high fasting blood glucose of, say, 118 mg/dl, then we aim to keep the one-hour after-eating blood glucose no higher than the pre-meal.

It works. Plain and simple.

This makes the primary care docs crazy: "How dare you check your blood sugar! You're not diabetic." In truth, blood glucose meters are relatively simple devices to use. The test strips and lancets will cost a few bucks. (The meters themselves are either low-cost or free, just like Gillette sometimes sends you a beautiful new razor for free but expects you to buy the blades). These are direct-to-consumer products. While a prescription written by your doctor for a glucose meter and supplies helps insurance cover the costs, you can easily get these devices without a prescription. Some stores, like Target, keep their devices out on the shelves with the shampoo and bath soap.

Warning: Anyone taking diabetes drugs will have to consult with their doctors about the safety of such an approach. Because this approach can actually cure diabetes in some people, if you are taking some diabetes drugs, especially glyburide, glipidize, and glimepiride, you can experience dangerously low blood sugars, just as any non-diabetic taking these drugs would.

Here are the results of the week-long poll asking the question:

Have you experienced a wheat re-exposure syndrome?

Yes, undesirable gastrointestinal effects 223 (41%)
Yes, asthma or sinus problems 51 (9%)
Yes, joint pains and/or swelling 85 (15%)
Yes, emotional or other nervous system effects 59 (10%) No, nothing, nada 107 (19%)

No. Wheat is sacred and you're all nuts 13 (2%)

There are several interesting observations to make from this informal poll. First, as I have observed, the most common wheat re-exposure syndrome is gastrointestinal, usually involving cramps, diarrhea, and lame explanations to your dinner partner.

Second most common: joint pains and/or swelling.

Third: asthma or sinus congestion.

The incidence of emotional or nervous system effects surprised me a bit. I didn't expect 10% of people to share this effect. This is an effect I also experience personally, along with the gastrointestinal consequences.

To be sure, this is a skewed poll, since many people likely come to this blog in the first place because of such issues. But I was nonetheless impressed with the relatively modest proportion of people who did not share such a re-exposure syndrome: only 19%.

Beyond the interesting numbers provided by readers, a good many also provided some fascinating and graphic comments. Here's a sample:

Reflux -- starts a day later and goes for up to a week. And Bloat:2-5 inches on my waistline in a day, lasting up to three. Miserable. And why, having experienced this once, have I done it often enough to verify the connection with certainty? I am working on that one.

Wheat increased hunger with even with only a small amount. Crackers in soup was enough to set it off.

Also, when I was trying to get off wheat, I noticed that 2 eggs and 2 bacon and I could go 5 hours before hunger, or 2 eggs and 2 bacon and toast was good for three hours before hunger. That was the final step to giving up wheat. Now three years and 59 Kg [130 lbs!] loss later, there is no doubt in my mind that wheat is evil, and I do not regard it as suitable for human food. I speculate that it increases ghrelin or cortisol.

For me, in the two years since I began eating Gluten-Free (Low Carb for 6 years), the few times I've had re-exposure to wheat, I've experienced fast onset and intense abdominal pain (known exposure during the daytime) and heartburn, indigestion, intense nausea, and disrupted sleep (exposures during evening meal not discovered until the next day).

My husband wants to think he's fine with wheat (though I know that he has at least one gene that predisposes to celiac), but IMO, he isn't. He eats no wheat at home because that's the default, and he's OK with that. But if he goes out to dinner at a restaurant that serves "good" artisan bread, he will indulge in a few bites (he does restrict his carb intake, so it's still a limited amount). More often than not, he will sleep fitfully on those nights, snore more, and wake in the night with indigestion. He wants to bury his head in the sand and will only acknowledge the discomfort being due to eating too many carbs, not the wheat itself. I notice he sleeps fine if he eats a small amount of potato or rice. Go figure.

Our 12 yo son has been eating GF for two years also. About 6 months into GF, he unknowingly ate wheat a number of times (licorice candy laces at a friend's house), which resulted in outbreaks of canker sores in his mouth each time. He also exhibits mood and behavior changes when he eats wheat, which is what prompted me to test him for gluten intolerance in the first place.

Mark said:

If I go for 3-4 days without wheat, grains or sugar and then go out and binge on a pizza and ice cream or something like that I become explosive within 20 minutes to an hour. It's like a wheat and sugar rage.(I'm not saying this is an excuse for rage, I'm saying it has happened to me and I believe partly do to re-exposure) It seems the combination of the wheat plus sugar can be the worst.

I get red rashes around my neck sometimes right away and sometimes up to a day or later and sometimes get bad diarrhea.

I think it can be almost dangerous to cut things like gluten and sugar suddenly out of the diet without being very serious about keeping them out. I have found it very hard to cut out wheat without binging on it later after 4 or 5 days. I don't believe that my symptoms are just psychological either.

I was also diagnosed with ADHD as a young kid and then rediagnosed with adult ADHD by 3 different doctors. I also have bouts of mania at times too. I am considering trying to go completely gluten/refined carbohydrate free to see if it helps with the symptoms and gives me some relief.

I have never been tested for celiac or gluten intolerance but I would like to be. I think it would help explain to my girlfriend, family and friends why I can't go out and eat pizza or have a beer or ice cream. Right now they all think I'm a hypochondriac. At times I have experienced an intense fatigue the next day like I can't wake up and also sharp pains in my body and headaches.

I ditched wheat a year ago after my wife was diagnosed celiac. I immediately experienced a number of health improvements (blood lipids, sleep, allergies, etc.).

Fast forward: We all suffered some inadvertent wheat exposure yesterday via some chocolate covered Brazil nuts (of all things). This accidental A-B-A experimental design resulted in the following:

1. My celiac wife experienced what she calls "the flip" within an hour of exposure (i.e., intense GI distress).
2. My five-year old son went to bed with some wicked reflux.
3. I woke up with some twinges in my lower back and an ache in my football-weary left shoulder. I was also complaining to my wife about fuzzy-headedness that refused to respond to caffeine or hydration. I could only describe it as "carb flu"...

And then I read your post!

Anne said:

Depression, agitation and brain fog if I get glutened. Some times this comes with abdominal pain and a rash on my back - I think it is dose dependent. Cross contamination with wheat is a big issue when eating out. Needless to say, I eat out infrequently and then try to stick with the restaurants that are the most aware of gluten issues.

Terrence said:

Several weeks ago, I started Robb Wolf's 30 day challenge.

The first two weeks were brutal - calling it a withdrawal flu was a massive understatement. So, I thought I would try some wheat and see what happened (could not be worse, I thought). Well, it was.

I still felt extremely crappy, but I was now MASSIVELY GASSY - AMAZINGLY GASSY, for about 48 hours - flatulence on wheels, in spades. I did not go out at all in those 48 hours - when the gas came on, it went out, LONG, and QUICKLY and LOUDLY.

I am easing back into wheat and grain free. I am gluten free today and tomorrow (Sunday and Monday). I expect to try a small amount of wheat on Thursday, then maybe a little more the following Thursday.

Donald said:

I have limited wheat consumption severely over the last 8 months. I have lost 120 pounds, no longer have bouts of illness, asthma, depression, or low energy. I also take vitamin D and other supplements that have helped (many are from your blog recommendations).

Last week I ate a small piece of cake and dessert pizza. Shortly thereafter I started sneezing, had a scratchy throat, and runny nose. I called off sick the next day for fear of being contagious. My symptoms subsided quickly and I am now attributing them to the processed flour eaten at my work luncheon. I think it was an allergic reaction since I recall having much more severe symptoms fairly regularly in my wheat eating days. Those were attributed to an "allergy" of unknown origin back then.

John said:

I suffered from Ankylosing Spondylitis, Iritis, Plantar Fasciits, etc for a number of years. I restricted carbs, especially wheat and I've been symptom free for the past two years now.

Lori said:

I found wheat to be one of the worst things for giving me gas bloating and acid reflux, and I'd had sinus and nasal congestion my whole life. When I ate that cookie, it just re-introduced old problems. I can occasionally eat a gluten-free, grainy goody at my party place without any side effects. I also have a little sprouted rice protein powder every day.

Another odd thing about wheat: it was hard for me to stop eating it once I started. I could go through a whole box of cookies in one sitting, even though I wasn't a binge eater. But I can have a couple of gluten-free cookies and stop.

Paul said:

Except for one slip up this recently past holiday season, I've been sugar-grain-starch free since July 2008. Mental fog was the most noticable re-exposure symptom I had.

My mom has had the worst acid-reflux for 40-plus years. It had become so bad that she was on three medications just to deal with the symptoms. After much training and coaxing, I finally got across to her how to totally get off wheat. Not at all to my surprise, after being wheat free for a few weeks, she lost weight and her acid reflux was GONE!

But she had been addicted to wheat for so long, she relapsed, and the reflux fire soon returned. Wheat must be akin to heroin with some people. Even though they know it's very bad for them, they can't help themselves.

Onschedule said:

Re-exposure often leads to diarrhea for me, or such a heavy feeling of tiredness that all I can do is lay down and pass out. A local pizzeria makes a darn good pie, but since I started practicing wheat-avoidance, I can't keep my eyes open after eating there. I can't say for sure that it's the wheat causing it, but definitely something in the crust. Diarrhea, on the other hand, is definitely triggered by the wheat for me.

My mom complained of gastric reflux for years, but never filled the prescriptions that her doctors would give her. I suggested wheat-avoidance- gastric reflux disappeared within 3 days and hasn't returned (has been 6 months now). I've already commented elsewhere on this blog about how much weight and bloating she has lost...

Steve said:

Interesting that I should sit down, turn on my computer and find your poll. Having gone several weeks, maybe months, avoiding gluten, I took my daughter and her boyfriend out to eat because my wife has been working late at the office lately. Although I was thinking I would just eat my steak and chicken, I succumbed to the temptation of eating about a dozen greasy, breaded shrimp that my daughter and her boyfriend ordered. It's 1:39am and I still do not feel sleepy. My left nostril is completely blocked, my stomach feels bloated, really, really full and I've been burping. In your poll I checked sinus problems but could have chose gastrointestinal or nervous problems just as well.

A few weeks ago my daughter brought home a pizza and, once again, despite my knowing that I shouldn't, I ate a couple of pieces. I was sick for two days. The pain in what I think was my transverse colon was so bad I thought I might have to go to ther emergency room. Before I ate the pizza I had never gone grain-free that long before. I did this after reading Robb Wolf's book.

I AM CONVINCED. No more wheat for me! Please, Lord, give me strength.

LV said:

What don't I experience! I typically avoid wheat (and gluten for that matter) as I'm pretty sure it makes me sick, but when I slip (or someone else slips me some) I end up with massive amounts of joint swelling and tenderness, diarhea, cramping, gas, bloating and brain fog. I'm absolutely miserable. Just that alone is enough to keep me off gluten. I have RA, so if I have repeated exposures I'll have a flare which SUCKS!

A carpenter wouldn't build a house using just his bare hands. You shouldn't stumble your way through nutritional blunders without the proper tools to guide you.

Best tool to lose weight:

Best tool to cure diabetes:

Best tool to reduce small LDL particles:

Best tool for anti-aging:

Observing blood sugar excursions after eating is proving to be among the most powerful tools I have come across.

Pretend I'm a mad food scientist. I'd like to create a food that:

1) Wreaks gastrointestinal havoc and cause intractable diarrhea, cramps, and anemia.
2) Kills some people who consume it after a long, painful course of illness.
3) Damages the brain and nervous system such that some people wet their pants, lose balance, and lose the ability to feel their feet and legs.
4) Brings out the mania of bipolar illness.
5) Amplifies auditory hallucinations in people with paranoid schizophrenia.
6) Makes people diabetic by increasing blood sugars.
7) Worsens arthritis, such as osteoarthritis and rheumatoid arthritis.
8) Triggers addictive eating behavior.
9) Punishes you with a withdrawal process if you try to remove it from your diet.

I will develop a strain that is exceptionally hardy and tolerates diverse conditions so that it can grow in just about any climate. It should also be an exceptionally high yield crop, so that I can sell it cheaply to the masses.

Now, if my evil scheme goes as planned, I will then persuade the USDA that not only is my food harmless, but it is good for health. If they really take the bait, they might even endorse it, create a diet program around it.

Dag nabit! Such a plan has already been implemented. Another evil food scientist already beat me to the punch. The food is called wheat.

Diabetics experience long-term health difficulties, including atherosclerosis/heart attacks, peripheral vascular disease, hypertension, cataracts, kidney disease, neuropathies, male erectile dysfunction, osteoarthritis, and colorectal cancer. They also die, on average, 10 years earlier than non-diabetics.

In effect, diabetics compress their lives into a shorter period of time. They experience all the "complications" of aging at a younger age. People without diabetes, of course, can develop atherosclerosis, cataracts, kidney disease, etc., but they tend to do so later in life compared to diabetics.

One index of the rate of aging (but not chronologic age itself) is hemoglobin A1c, or HbA1c, a "moving average" of glycated hemoglobin, i.e., glucose-modified hemoglobin. Blood glucose glycates hemoglobin linearly and irreversibly; measuring HbA1c thereby provides an index of the last 60 or so days average blood glucose.

To put HbA1c values into perspective:

Average HbA1c of hunter-gatherers: 4.5%
Average HbA1c for Americans: 5.6%
American Diabetes Association definition of diabetes: 6.5% or greater
American Diabetes Association definition of adequate control of diabetes: 7.0% or less

Why do diabetics age faster? There are likely several reasons. One important reason is glycation, as indexed by HbA1c. Glycated proteins in the lens of the eye causes cataracts. Glycated proteins in cartilage leads to arthritis. Glycated LDL particles (apo B) leads to atherosclerosis. Glycated nerve cells causes neuropathy. And so on.

If glycation underlies many of the phenomena of aging, then we might surmise that:

1) The less you glycate, the slower you age.
2) The more you glycate, the faster you age.

Therefore, the higher the HbA1c, the faster you are aging.

What foods increase HbA1c? Carbohydrates. That bowl of slow-cooked, stone ground oatmeal? A one-hour after-eating blood sugar of 170 mg/dl is common. Your doctor says that's okay because it's below 200 mg/dl and you don't "need" medication yet.
