Krill oil: Do the math 21. mayo 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. mayo 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. noviembre 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. noviembre 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. octubre 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. octubre 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( All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in All in the family--What to do if there's heart disease in your family 3. April 2006 William Davis (0) What should you do if a close relative of yours is diagnosed with coronary disease?This question came up recently with a patient of mine. The patient--a strapping, 47 year old businessman who looked the absolute picture of health--was undergoing bypass surgery. Although I'd met him for the purposes of plaque reversal, he was already having symptoms and his stress test was flagrantly abnormal, all discovered after a heart scan score of 765. On the day after the patient's bypass, the patient's brother came to me. Understandably concerned about his own health, he asked what he should do. The answer: get a heart scan.Measure the disease with the easiest test available. If his heart scan score is zero, great--he's at exceptionally low (near zero) risk for heart attack. A modest program of long-term prevention is all that's necessary. What if his score is like his brother, should he get in line for his bypass? No, absolutely not! But he will need two things: 1) a stress test to ascertain whether or not he's safe (60% likelihood a stress test would be normal), and 2) an effort to determine how the heck he got so much plaque. (We favor lipoprotein testing, of course, for greatest diagnostic certainty.) Message: Learn from the lessons your own family provides. Don't let this valuable information go to waste.
