Krill oil: Do the math 21. May 2013 William Davis (0) 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 mgTotal omega-3s (EPA + DHA + other forms) 90 mgPrice: $28.99 for 60 softgelsSource Naturals (a fine company otherwise, by the way):EPA 150 mgDHA 90 mgTotal omega-3 fatty acids 300 mg Price: $24.99 for 60 softgelsAlright, let's do some simple math:Average volume of blood in the human body (all components): 5000 ccPercentage of red blood cells (RBCs) by volume: 45%Total volume RBCs: 2250 ccPercentage of total volume RBCs occupied by fatty acids:
What tests are MORE important than cholesterol? 12. May 2013 William Davis (8) 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.
Cranberry Sauce 21. November 2012 William Davis (3) 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 water12 ounces fresh whole cranberriesSweetener equivalent to 1 cup sugar (I used 6 tablespoons Truvía)1 tablespoon orange zest + juice of half an orange½ cup chopped walnuts1 teaspoon ground cinnamon½ teaspoon ground nutmeg¼ teaspoon ground clovesIn 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 Crumble 18. November 2012 William Davis (0) 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 topping3 cups almond meal1 stick (8 tablespoons) butter, softened 1 cup xylitol (or other sweetener equivalent to 1 cup sugar) 1½ teaspoons ground cinnamon1 tablespoon molasses1½ teaspoons vanilla extract Dash sea saltFilling16 ounces cream cheese, softened2 large eggs½ cup xylitol (or other sweetener equivalent to ½ cup sugar)1 Granny Smith apple (or other variety)1 teaspoon ground cinnamon1 cup fresh cranberriesPreheat 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 19. October 2012 William Davis (5) 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 biscuitsGravy:2 tablespoons extra-virgin olive oil1 pound loose sausage meat2½ cups beef broth¼ cup coconut flour½ cup coconut milk (canned variety)1 tablespoon onion powder1 teaspoon garlic powder½ teaspoon sea saltDash ground black pepperBiscuits:1 cup shredded cheddar (or other) cheese2 cups almond meal/flour¼ cup coconut flour¾ teaspoon baking soda½ teaspoon sea salt2 large eggs4 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.
The Perfect Carnivore 2. October 2012 William Davis (19) 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 infectionsIn 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. < Toggle navigation Home Blog Home Archive Join Now Log in Diabetes: Better than hedge funds 7. March 2011 William Davis (23) Diabetes is where the action is. While, for virtually all of history, type 2 diabetes was an uncommon condition of adults, the disease has spread so much to all levels of American society that even kids are now developing the adult form. Researchers from the Center for Disease Control and Prevention predict that, by 2050, one in three adults will be diabetic. The diabetes market is booming, handily surpassing growth of the oil industry, the housing market, even technology. It makes Bernie Madoff’s billions look like small potatoes. In health, few markets are growing as fast as diabetes—-not osteoporosis, not heart disease, not cancer. Americans are getting fat from carbohydrate consumption, becoming diabetic along with it. While kids hanging around the convenience store gulp down 26 teaspoons of sugar in 32-ounce sodas and 56-grams-of-sugar in 16-ounce frozen ices, health-minded adults are more likely eating two slices of 6-teaspoons sugar-equivalent “healthy whole grain” bread, wondering why last year’s jeans are too tight. The U.S. is not the only nation affected. Globally, 2.8% of the world’s population are diabetic, a number expected to double over the next 20 years. Pharmaceutical companies boast double-digit growth for diabetes drugs, growth rates that keep profit-hungry investors happy. Merck’s Januvia, for instance, introduced in 2006, recently catalogued 30% growth in sales, with annual sales approaching $1 billion. Recently FDA-approved Victoza, requiring once-a-day injection, is expected to reap $4 billion in sales per year for manufacturer Novo Nordisk. Such numbers can only warm a drug company CEO’s heart. Most diabetics don’t just take one medication, but several. A typical regimen for an adult diabetic after a couple of years of treatment and following the dietary advice of the American Diabetes Association includes metformin, Januvia, and Actos, a triple-drug treatment that costs around $420 per month. Two forms of insulin (slow- and fast-acting), along with two or three oral medications, is not at all uncommon. “Collateral” revenues from the other health conditions that develop from a diet rich in “healthy whole grains,” such as drugs for hypertension, drugs to slow the progression of kidney disease in diabetes, drugs for “high cholesterol,” and drugs for high triglycerides, and you have a pharmaceutical drug bonanza. You, too, would throw all-expenses-paid, fly-the-entire-sales-force-to-the-Caribbean sales meetings. The global diabetes market has already topped $25 billion and is growing at double-digit rates. Forget the Internet, gold stocks, or solar energy—-diabetes is where the money is. This fact has not been lost on the very market-savvy pharmaceutical industry. As with any successful business, they have devoted substantial resources to develop and grow this booming business. 270 lb man in diapers 5. March 2011 William Davis (20) Alex is a big guy: 6 ft 4 inches, 273 lbs. On 10,000 units per day of vitamin D in gelcap form, his 25-hydroxy vitamin D level was 38.4 ng/ml. One year earlier, his 25-hydroxy vitamin D level, prior to any vitamin D supplementation was 9.8 ng/ml. According to the latest assessment offered by the Institute of Medicine (IOM):Vitamin D need for a 13-month old infant: 600 units per dayVitamin D need for a 6 ft 4 in, 273 lb male: 600 units per dayI paint this picture to highlight some of the absurdity built into the smug assumptions of the IOM's report. It would be like trying to fit a large, full-grown man into the diapers of a 13-month old. Few nutrients or hormones (in fact, I can't think of a single one) are required in similar quantity by an infant or toddler and a full grown adult. However, according to the IOM's logic, their vitamin D needs are identical, regardless of age, body size, skin color, genetics, etc. One size fits all.Just as the original RDA assessment by the Institute of Medicine kept thinking about vitamin D somewhere in the Stone Age, so does this most recent assessment. 90% small LDL: Good news, bad news 4. March 2011 William Davis (11) Chris has 90% small LDL particles. On his (NMR) lipoprotein panel, of the total 2432 nmol/L LDL particles ("LDL particle number"), 2157 nmol/L are small, approximately 90% (2157/2432).Bad news: Having this severe excess of small LDL particles virtually guarantees heart attack and stroke in Chris' future.Good news: It means that Chris potentially has spectacular control over his lipoprotein and lipid values, achieving statin-like values without statin drugs.Typically, extravagant quantities of small LDL particles are accompanied by low HDL, high triglycerides, and pre-diabetes or diabetes. Chris' HDL is 26 mg/dl, triglycerides 204 mg/dl; HbA1c 5.9% (a reflection of prior 60-90 days average blood glucose; desirable 4.8% or less), fitting neatly into the expected pattern.Chris' pattern tells me several things:1) He overconsumes carbohydrates, since carbohydrates trigger this pattern.2) He likely has a genetic susceptibility to this effect (e.g., a variant of the gene for cholesteryl ester transfer protein, perhaps hepatic lipase). Only the most gluttonous and overweight carbohydrate consumers can generate this high a percentage small LDL without an underlying genetic susceptibility. 3) Provided he follows the diet advised, i.e., elimination of all wheat, cornstarch, oats, and sugars, he is likely to have an extavagant drop in LDL particle number. Should he achieve the goal I set of small LDL of 300 nmol/L or less, his LDL particle number will likely be around 500 nmol/L. This translates to an LDL cholesterol of 50 mg/dl . . . 50 mg/dl. In many people, this notion of taking statin drugs for "high cholesterol" is an absurd oversimplification. But it is a situation that, for many, is wonderfully controllable with the right diet. The American Heart Association has a PR problem 2. March 2011 William Davis (17) The results of the latest Heart Scan Blog poll are in. The poll was prompted by yet another observation that the American Heart Association diet is a destructive diet that, in this case, made a monkey fat. Because I am skeptical of "official" organizations that purport to provide health advice, particularly nutritional advice, I thought this poll might provide some interesting feedback. I asked:The American Heart Association is an organization that:The responses:Tries to maintain the procedural and medication status quo to benefit the medical system and pharmaceutical industry for money240 (64%)Doesn't know its ass from a hole in the ground121 (32%)Is generally helpful but is misguided in some of its advice79 (21%)Accomplishes tremendous good and you people are nuts6 (1%)Worrisome. Now, perhaps the people reading this blog are a skeptical bunch. Or perhaps they are better informed. Nonetheless, one thing is clear: The American Heart Association (and possibly other organizations like the American Diabetes Association and USDA) have a serious PR problem. They are facing an increasingly critical and skeptical public. Just telling people to "cut the fat and cholesterol" is beginning to fall on deaf ears. After all, the advice to cut fat, cut saturated fat, cut cholesterol and increase consumption of "healthy whole grains" in 1985 began the upward ascent of body weight and diabetes in the American public.Believe it or not, my vote would be for something between choices 1 and 3. I believe that the American Heart Association achieves a lot of good. But I also believe that there are forces within organizations that are there to serve their own agendas. In this case, I believe there is a substantial push to maintain the procedural and medication status quo, the "treatments" that generate the most generous revenues. I believe that I will forward these poll results to the marketing people at the American Heart Association. That'll be interesting! The formula for aortic valve disease? 28. February 2011 William Davis (60) I've discussed this question before:Can aortic valve stenosis be stopped or reversed using a regimen of nutritional supplements?I had a striking experience this past week. Don has coronary plaque and began the Track Your Plaque program. However, discovery of a murmur led to an echocardiogram that measured his effective aortic valve area at 1.5 cm2. (Normal is between 2.5-3.0 cm2.) Because of his aortic valve issue, I suggested that, in addition to the 10,000 units of vitamin D required to increase his 25-hydroxy vitamin D level to 70 ng/ml, he also add vitamin K2, 1000 mcg per day, along with elimination of all calcium supplements. (I asked Don to use a K2 supplement that contained both forms, short-acting MK-4 and long-acting MK-7.) One year later, another echocardiogram: aortic valve area 2.6 cm2--an incredible increase. This is not supposed to happen. By conventional thinking, aortic valve stenosis can only get worse, never get better. But I've now witnessed this in approximately 10% of the people with aortic valve stenosis. The majority just stop getting worse, an occasional person gets worse, while a few, like Don, get better. Aortic valve stenosis is to the aortic valve as degenerative arthritis is to your knees: A form of wear-and-tear that leads to progressive dysfunction. When the aortic valve becomes stiff enough (i.e., "stenotic"), then it leads to chest pains, lightheadedness or losing consciousness, heart failure, and, eventually, death. Bad problem. Aortic stenosis typically starts in your 50s with calcification of the valve, getting worse and worse until the calcium makes the valve "leaflets" unable to move. The treatment: a new valve, a major undertaking involving an open heart procedure. What if taking vitamins D and K2 and avoiding calcium do not just reverse or stop aortic valve stenosis once established, but prevents it in the first place? Tantalizing possibility.Pressures on my time being what they are, I've not had the freedom to put together a prospective study to further examine this fascinating question. But it is definitely worth pursuing. Blood glucose 160 26. February 2011 William Davis (28) What happens when blood glucose hits 160 mg/dl? A blood glucose at this level is typical after, say, a bowl of slow-cooked oatmeal with no added sugar, a small serving of Cheerios, or even an apple in the ultra carb-sensitive. Normal blood sugar with an empty stomach, i.e., fasting; high blood sugars after eating. Conventional wisdom is that a blood sugar of 160 mg/dl is okay, since your friendly primary care doctor says that any postprandial glucose of 200 mg/dl or less is fine because you don't "need" medication. But what sort of phenomena occur when blood sugars are in this range? Here's a list:--Glycation (i.e., glucose modification of proteins) of various tissues, including the lens of your eyes (cataracts), kidney tissue leading to kidney disease, skin leading to wrinkles, cartilage leading to stiffness, degeneration, and arthritis. --Glycation of LDL particles. Glycated LDL particles are more prone to oxidation. --VLDL and triglyceride production by the liver, i.e., de novo lipogenesis.--Small LDL particle formation--The increased VLDL/triglyceride production leads to the CETP-mediated reaction that creates small LDL particles which are, in turn, more glycation- and oxidation-prone. --Glucotoxicity--i.e., a direct toxic effect of high blood glucose. This is especially an issue for the vulnerable beta cells of the pancreas that produce insulin. Repeated glucotoxic poundings by high glucose levels lead to fewer functional beta cells. A blood glucose of 160 mg/dl is definitely not okay. While it is not an immediate threat to your health, repeated exposures will lead you down the same path that diabetics tread with all of its health problems. Indian buffet 24. February 2011 William Davis (56) 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 not supposed to happen. By conventional thinking, aortic valve stenosis can only get worse, never get better. But I've now witnessed this in approximately 10% of the people with aortic valve stenosis. The majority just stop getting worse, an occasional person gets worse, while a few, like Don, get better. Aortic valve stenosis is to the aortic valve as degenerative arthritis is to your knees: A form of wear-and-tear that leads to progressive dysfunction. When the aortic valve becomes stiff enough (i.e., "stenotic"), then it leads to chest pains, lightheadedness or losing consciousness, heart failure, and, eventually, death. Bad problem. Aortic stenosis typically starts in your 50s with calcification of the valve, getting worse and worse until the calcium makes the valve "leaflets" unable to move. The treatment: a new valve, a major undertaking involving an open heart procedure. What if taking vitamins D and K2 and avoiding calcium do not just reverse or stop aortic valve stenosis once established, but prevents it in the first place? Tantalizing possibility.Pressures on my time being what they are, I've not had the freedom to put together a prospective study to further examine this fascinating question. But it is definitely worth pursuing.
Blood glucose 160 26. February 2011 William Davis (28) What happens when blood glucose hits 160 mg/dl? A blood glucose at this level is typical after, say, a bowl of slow-cooked oatmeal with no added sugar, a small serving of Cheerios, or even an apple in the ultra carb-sensitive. Normal blood sugar with an empty stomach, i.e., fasting; high blood sugars after eating. Conventional wisdom is that a blood sugar of 160 mg/dl is okay, since your friendly primary care doctor says that any postprandial glucose of 200 mg/dl or less is fine because you don't "need" medication. But what sort of phenomena occur when blood sugars are in this range? Here's a list:--Glycation (i.e., glucose modification of proteins) of various tissues, including the lens of your eyes (cataracts), kidney tissue leading to kidney disease, skin leading to wrinkles, cartilage leading to stiffness, degeneration, and arthritis. --Glycation of LDL particles. Glycated LDL particles are more prone to oxidation. --VLDL and triglyceride production by the liver, i.e., de novo lipogenesis.--Small LDL particle formation--The increased VLDL/triglyceride production leads to the CETP-mediated reaction that creates small LDL particles which are, in turn, more glycation- and oxidation-prone. --Glucotoxicity--i.e., a direct toxic effect of high blood glucose. This is especially an issue for the vulnerable beta cells of the pancreas that produce insulin. Repeated glucotoxic poundings by high glucose levels lead to fewer functional beta cells. A blood glucose of 160 mg/dl is definitely not okay. While it is not an immediate threat to your health, repeated exposures will lead you down the same path that diabetics tread with all of its health problems.
Indian buffet 24. February 2011 William Davis (56) 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.
