Lessons from the 20-year statin experience 2. November 2011 William Davis (0) Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages. Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:
Small LDL particles and increased HbA1c--An evil duo 30. October 2011 William Davis (53) Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket. Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis. Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation. So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque. The key is therefore to tackle both small LDL particles and HbA1c.
Unforgiving small LDL particles 21. October 2011 William Davis (39) Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particles, carbohydrate reduction results in marked reduction in small LDL particle formation.So let's say you are doing great and you've slashed carbohydrates. Small LDL particles are now down to zero--no small LDL whatsoever. What LDL particles you have are the more benign large variety, say, 1200 nmol/L (LDL particle number), all large, none small. You are due for some more blood work on Thursday. On Tuesday, however, you have four crackers because, what the heck, you've been doing great, you've lost 43 pounds, and have been enjoying dramatic correction of your lipoprotein abnormalities.Your next lipoprotein panel: LDL particle number 1800 nmol/L, small LDL 700 nmo/L--substantially worse, with a major uptick in small LDL.That's how sensitive small LDL particles can be to carbohydrate intake. And the small LDL particles can last for up to several days, since small LDL particles are not just smaller in size, they also differ in conformation, making them unrecognizable by the normal liver receptor. The small LDL particles triggered by the 4 crackers therefore linger, outlasting the normal-conformation large LDL particles that are readily cleared by the liver. This phenomenon is responsible for great confusion when following lipoprotein panels, since a 98% perfect diet can yield dismaying results just from a minor indulgence. But, buried in this simple observation is the notion that small LDL particles are also extremely unforgiving, being triggered by the smallest carbohydrate indulgence, lasting longer and wreaking their atherosclerotic plaque havoc.
I eliminated wheat . . . and I didn't lose weight! 19. October 2011 William Davis (33) Elimination of wheat is a wonderfully effective way to lose weight. Because saying goodbye to wheat means removing the gliadin protein of wheat, the protein degraded to brain-active exorphins that stimulate appetite, calorie consumption is reduced, on average, 400 calories per day. It also means eliminating this source of high blood sugar and high blood insulin and the 90-minutes cycles of highs and lows that cause a cyclic need to eat more at the inevitable low. It means that the high blood sugar and insulin phenomena that trigger accumulation of visceral fat are now turned off. It may possibly also mean that wheat lectins no longer block the leptin receptor, undoing leptin resistance and allowing weight loss to proceed. And weight loss usually results effortlessly and rapidly.But not always. Why? Why are there people who, even after eliminating this appetite-stimulating, insulin-triggering, leptin-blocking food, still cannot lose weight? Or stall after an initial few pounds?There are a list of reasons, but here are the biggies:1) Too many carbohydrates--What if I eliminate wheat but replace those calories with gluten-free breads, muffins, and cookies? Then I've switched one glucose-insulin triggering food for another. This is among the reasons I condemn gluten-free foods made with rice starch, cornstarch, tapioca starch, and potato starch. Or perhaps there's too many potatoes, rices, and oats in your diet. While not as harmful as wheat, they still provoke phenomena that cause weight loss to stall. So cutting carbohydrates may become necessary, e.g., no more than 12-14 grams per meal.2) Fructose--Fructose has become ubiquitous and has even assumed some healthy-appearing forms. "Organic agave nectar" is, by far, the worst, followed by maple syrup, honey, high-fructose corn syrup, sucrose,and fruit--yes, in that order. They are all sources of fructose that causes insulin resistance, visceral fat accumulation or persistency, prolongation of clearing postprandial (after-meal) lipoproteins that antagonize insulin, and glycation. Lose the fructose sources--as much of it as possible. (Fruit should be eaten in very small portions.) Watch for stealth sources like low-fat salad dressings--you shouldn't be limiting your fat anyway!3) Thyroid dysfunction--A real biggie. Number one cause to consider for thyroid dysfunction: iodine deficiency. Yes, it's coming back in all its glory, just like the early 20th century before iodized salt made it to market shelves. Now, people are cutting back on iodized salt. Guess what's coming back? Iodine deficiency and even goiters. Yes, goiters, the disfiguring growths on the neck that you thought you'd only see in National Geographic pictures of malnourished native Africans. Number two: Exposure to factors that block the thyroid. This may include wheat, but certainly includes perchlorate residues (synthetic fertilizer residues) on produce, pesticides, herbicides, polyfluorooctanoic acid residues from non-stick cookware, polybrominated diphenyl ethers (flame retardants), and on and on. If you are iodine-deficient, it can even include goitrogenic iodine-blocking foods like broccoli, cauliflower, and soy. Thyroid status therefore needs to be assessed.4) Cortisol--Not so much excess cortisol as disruptions of circadian rhythm. Cortisol should surge in the morning, part of the process to arouse you from sleep, then decline to lower levels in the evening to allow normal recuperative sleep. But this natural circadian cycling is lost in many people represented, for instance, as a flip-flopping of the pattern with low levels in the morning (with morning fatigue) and high levels at bedtime (with insomnia), which can result in stalled weight loss or weight gain. Cortisol status therefore needs to be assessed, best accomplished with salivary cortisol assessment.5) Leptin resistance--People who are overweight develop an inappropriate resistance to the hormone, leptin, which can present difficulty in losing weight. This can be a substantial issue and is not always easy to overcome. It might mean assessing leptin levels or it might mean taking some steps to overcome leptin resistance.Okay, that's a lot. Next: More on how to know when thyroid dysfunction is to blame.
Do the math: 41.7 pounds per year 14. October 2011 William Davis (21) Consumers of wheat take in, on average, 400 calories more per day. Conversely, people who eliminate wheat consume, on average, 400 calories less per day.400 calories per day multiplied by 365 days per day equals 146,000 additional calories over the course of one year. 146,000 calories over a year equals 41.7 pounds gained per year. Over a decade, that's 417 pounds. Of course, few people actually gain this much weight over 10 years.But this is the battle most people who follow conventional advice to "cut your fat and eat more healthy whole grains" are fighting, the constant struggle to subdue the appetite-increasing effects of the gliadin protein of wheat, pushing your appetite buttons to consume more . . . and more, and more, fighting to minimize the impact.So, if you eat "healthy whole grains" and gain "only" 10 pounds this year, that's an incredible success, since it means that you have avoided gaining the additional 31.7 pounds that could have accumulated. It might mean having to skip meals despite your cravings, or exercising longer and harder, or sticking your finger down your throat.400 additional calories per day times 365 days per year times 300,000,000 people in the U.S. alone . . . that's a lot of dough. Is this entire scenario an accident?Or, of course, you could avoid the entire situation and kiss wheat goodbye . . . and lose 20, 30, or 130 pounds this year.
We got the drug industry we deserve 14. October 2011 William Davis (6) A biting commentary on just who is writing treatment guidelines for diabetes and cardiovascular disease was published in the British Medical Journal, summarized in theHeart.org's HeartWire here. "About half the experts serving on the committees that wrote national clinical guidelines for diabetes and hyperlipidemia over the past decade had potential financial conflicts of interest (COI), and about 4% had conflicts that were not disclosed."Five of the guidelines did not include a declaration of the panel members' conflicts of interest, but 138 of the 288 panel members (48%) reported conflicts of interest at the time of the publication of the guideline. Eight reported more than one conflict. Of those who declared conflicts, 93% reported receiving honoraria, speaker's fees, and/or other kinds of payments or stock ownership from drug manufacturers with an interest in diabetes or hyperlipidemia, and 7% reported receiving only research funding. Six panelists who declared conflicts were chairs of their committee."Of the 73 panelists who had a chance to declare a conflict of interest but declared none, eight had undeclared COI that the researchers identified by searching other sources. Among the 77 panel members who did not have an opportunity to publicly declare COI in the guidelines documents, four were found to have COI."The closing quote by Dr. Edwin Gale of the UK is priceless: "Legislation will not change the situation, for the smart money is always one step ahead. What is needed is a change of culture in which serving two masters becomes as socially unacceptable as smoking a cigarette. Until then, the drug industry will continue to model its behavior on that of its consumers, and we will continue to get the drug industry we deserve."It's like having Kellogg's tell us what to each for breakfast, or Toyota telling us what car to drive. The sway of the drug industry is huge. Even to this day, I observe colleagues kowtow to the sexy sales rep hawking her wares. But that's the least of it. Far worse, even the "experts" who we had trusted to have objectively reviewed the evidence to help the practitioner on Main Street appears to be little more than a hired lackey for Big Pharma, hoping for that extra few hundred thousand dollars.
Wheat "debate" on CBC 11. October 2011 William Davis (29) "Many Canadians plan warm buns, stuffing and pie for their Thanksgiving meals tonight. But I'll speak with a cardiologist who thinks we have no reason to be thankful for any food that contains wheat. William Davis says our daily bread is making us fat and sick."That's the introduction to my recent interview and debate on CBC, the Canadian public radio system, aired on the Canadian Thanksgiving. Arguing the other side was Dr. Susan Whiting, an academic nutritionist. (I use the word "arguing" loosely, since she hardly argued the issues, certainly hadn't read the book, but was content to echo the conventional line that whole grains are healthy and cutting out a food group is unhealthy.) I do have to give credit to the Canadian media, including the CBC, who have been hosting some rough-and-tumble discussions about the entire wheat question despite Canada being a world exporter of wheat. I recently participated in another debate with a PhD nutrition expert from Montreal who, in response to my assertion that the genetically-altered high-yield, semi-dwarf strains have changed the basic composition of wheat, argued that the creation of the 2-foot tall semi-dwarf strain was a convenience created so that farmers could see above their fields--no kidding. I stifled my laugh. (The semi-dwarf variants were actually created to compensate for the heavy seed head that develops with vigorous nitrate fertilization that buckles 4 1/2-foot tall wheat stalk, making harvesting and threshing impossible, a process farmers call "lodging." The 2-foot tall semi-dwarf thick, stocky stalk is strong enough to resist lodging.) In short, debating the nutrition "experts" on this question has been tantamount to arguing with a school age child on the finer points of quantum physics. There has not yet been any real objection raised on the basic arguments against modern genetically-altered wheat. Modern semi-dwarf wheat is, and remains, an incredibly bad creation of the genetics laboratories of the 1970s. It has no business on the shelves of your grocery store nor on the cupboards in your home.
Carrot Cake 5. October 2011 William Davis (14) This is among my favorite recipes from the Wheat Belly book. I reproduce it here for those of you who read the Kindle or audio version and therefore didn't get the recipes.I made this most recently this past weekend. It was gone very quickly, as even the 13-year old gobbled it up.(I reduced the sour cream in this version from 8 to 6 oz to reduce cooking time. Also, note that anyone trying to avoid dairy can substitute more coconut milk, i.e., the thicker variety, in equivalent quantities.)Makes 8-10 servings Ingredients:Cake:2 cups carrots, finely grated1 cup chopped pecans1 cup coconut flour1 tablespoon ground flaxseed2 teaspoons ground cinnamon1 teaspoon allspice1 teaspoon nutmeg1 teaspoon baking powder2 tablespoons freshly grated orange peelSweetener equivalent to ½ cup sugar (e.g., 4 tablespoons Truvia)½ teaspoon sea salt4 eggs1/2 cup butter or coconut oil, melted2 teaspoons vanilla extract½ cup coconut milk6 ounces sour creamIcing:8 ounces cream cheese or Neufchâtel cheese, softened1 teaspoon lemon juice1 tablespoon Truvía or 1/8 teaspoon stevia extract powder or ¼ cup SplendaPreheat oven to 325° degrees F. Grate carrots and set aside.Combine coconut flour, flaxseed, cinnamon, nutmeg, baking powder, orange peel, sweetener, and salt in large bowl and mix by hand.Put eggs, butter or coconut oil, vanilla coconut milk, and sour cream in mixing bowl; mix by hand.

Add lemon juice and sweetener and mix thoroughly. Spread on cake.
Why wheat makes you fat 1. October 2011 William Davis (32) How is it that a blueberry muffin or onion bagel can trigger weight gain? Why do people who exercise, soccer Moms, and other everyday people who cut their fat and eat more "healthy whole grains" get fatter and fatter? And why weight gain specifically in the abdomen, the deep visceral fat that I call a "wheat belly"?There are several fairly straightforward ways that wheat in all its varied forms--whole wheat bread, white bread, multigrain bread, sprouted bread, sourdough bread, pasta, noodles, bagels, ciabatta, pizza, etc. etc.--lead to substantial weight gain:High glucose and high insulin--This effect is not unique to wheat, but shared with other high-glycemic index foods (yes: whole wheat has a very high-glycemic index) like cornstarch and rice starch (yes, the stuff used to make gluten-free foods). The high-glycemic index means high blood glucose triggers high blood insulin. This occurs in 90- to 120-minute cycles. The high insulin that inevitably accompanies high blood sugar, over time and occurring repeatedly, induces insulin resistance in the tissues of the body. Insulin resistance causes fat accumulation, specifically in abdominal visceral fat, as well as diabetes and pre-diabetes. The more visceral fat you accumulate, the worse insulin resistance becomes; thus the vicious cycle ensues. Cycles of satiety and hunger--The 90- to 120-minute glucose/insulin cycle is concluded with a precipitous drop in blood sugar. This is the foggy, irritable, hungry hypoglycemia that occurs 2 hours after your breakfast cereal or English muffin. The hypoglyemia is remedied with another dose of carbohydrate, starting the cycle over again . . . and again, and again, and again. Gliadin proteins--The gliadin proteins unique to wheat, now increased in quantity and altered in amino acid structure from their non-genetically-altered predecessors, act as appetite stimulants. This is because gliadins are degraded to exorphins, morphine-like polypeptides that enter the brain. Exorphins can be blocked by opiate-blocking drugs like naltrexone. A drug company has filed an application with the FDA for a weight loss indication for naltrexone based on their clinical studies demonstrating 22 pounds weight loss after 6 months treatment. Overweight people given an opiate blocker reduce calorie intake 400 calories per day. But why? There's only one food that yields substantial quantities of opiate-like compounds in the bloodstream and brain: wheat gliadin. Leptin resistance--Though the data are preliminary, the lectin in wheat, wheat germ agglutinin, has the potential to block the leptin receptor. Leptin resistance is increasingly looking like a fundamental reason why people struggle to lose weight. This might explain why eliminating, say, 500 calories of wheat consumption per day yields 3500 calories of weight loss. And, as in many things wheat, the whole is greater than the sum of the parts. Despite all we know about this re-engineered thing called wheat, eliminating it yields health benefits, including weight loss, that seem to be larger than what you'd predict with knowledge of all its nasty little individual pieces.
Just who is "Real Facts 2000"? 29. September 2011 William Davis (38) This is an example of what seems to be developing over at Amazon.com, posted as a "book review": The author has no credentials, no credibility, just a small cult of terribly misinformed followers. Don't be fooled by the high volume screech against wheat and grains. Allegations of "secret ingredients in wheat" to make you eat more, or comparisons to cigerettes. Seriously?! For over 8000 years wheat has sustained and grown human kind, oh and it tastes good when mixed with a little water and yeast. Every nutritionist and serious medical professional will tell you that bread is the most economical and safe source of essential nutrients. In fact, bread is handed out in natural disasters because it sustains life without food safety issues or requiring refrigeration. And now, suddenly it will kill you. Comical! This book is such a bone headed, misinformed way to just scare people into not eating. As for secret ingredients, humm, apparently the author is ignorant of the food laws that regulate everything that goes into food and on food labels. Unlike some enforcement agencies, the FDA has some serious teeth behind its enforcement. As for frankenwheat, again seriously?! Wheat, due to its ubiquitous presence in the world is treated as sacrosant from any GMO research or development. If you need real, science based information on healthy eating, check out [...] and leave this book and its cult in the compound.If you recognize the wording and tone, you will readily recognize the footprints of the Wheat Lobby here. "Terribly misinformed followers"? . . . Hmmm. "Food laws"? I didn't realize that eating more "healthy whole grains" was a . . . law?Make no mistake: There are people and organizations who have a heavy stake in your continued consumption of the equivalent of 300 loaves of bread per year. There are people and organizations (read: pharmaceutical industry) who have a big stake on the "payoff" of your continued consumption of "healthy whole grains." This is not a book review; this is part of a concerted, organized campaign to discredit a message that needs to be heard. Anybody from the media listening?
How old are you? 17. October 2009 William Davis (21) George walks into my office. I ask him his age. "I'm 21 years old," he declares. Yet I look at George. He's got gray thinning hair, his posture is slumped forward rather than erect, the flesh on his upper arms hangs loosely, he's got wrinkles on his hands and face, brown spots on the back of his hands and arms. He looks more like 70 years old to me. "I don't think you're 21 years old. I think you're 70.""Prove it," he says.Okay. What now? Minus any formal identification like a driver's license, how do I prove that George is really 70-something and not 20-something? Not an easy thing, when you think about it. If George were a tree, I'd cut him down and count his rings. Is there such a phenomenon in humans? This is actually a fascinating area of research, looking for reliable biomarkers of aging. Among the most quantitative markers of aging is telomere length. Telomeres were once dismissed as nonsense sequences in DNA. However, more recent thought among geneticists is that telomeres shorten with aging and provide the body's cells a timeline of aging. This way, George's cells act like they are 70, not 13, and don't start producing gobs of growth hormone and testosterone in preparation for puberty. What can slow or stall the shortening of telomere length? There are two I'm aware of:1) Caloric deprivation--i.e., taking in fewer calories. This was among the theories explored by Dr. Roy Walford during his Biosphere2 experience, based on his work in mice that showed that caloric deprivation nearly doubled lifespan. 2) Vitamin D--Richards et al (2007) found that, the higher the vitamin D, the longer the telomere length. The highest vitamin D levels conferred a 5-year effective difference in telomere length. So, if I could look inside George's cells and count his telomeres, I could judge with confidence whether he was 21 or 70. Or, he could take vitamin D sufficient to increase blood levels to a healthy range and be more like 65.
No high blood pressure 14. October 2009 William Davis (20) Primitive cultures that were, until recently, unexposed to the modern world, reveal some important insights into blood pressure. The Yanomamo of South American, the Xingu Indians of Brazil, rural Kenyans, and the natives of Papua, New Guinea have average blood pressures of 103/63 mmHg. Even more incredibly, while 90% of modern Americans will develop high blood pressure as they age, the members of these primitive cultures do not develop age-related hypertension. What's the secret? Perhaps the full "secret" of their remarkably low blood pressure has not been fully unraveled, but several observations have emerged:--They are not exposed to modern processed foods like pretzels, crackers, and breakfast cereals. --Low-carbohydrate foods. Carbohydrates are largely the product of the food industry, convenience foods bought in stores. No such thing in the jungle. --Living outdoors, having to forage and hunt, walk to your destination, not drive or wait in line for food. --Outdoor lives, wearing little more than a few strands of clothing, exposes you to plentiful vitamin D activation from sunlight exposure.--Consuming wild game, rich in omega-3 fatty acids, enhances endothelial health and reduces blood pressure. --Wild plants, roots, and berries, as well as wild game, along the coast, are richer in iodine. The studies examining the habits of the Yanomamo and other primitive cultures focused principally on sodium intake. Indeed, the very low sodium intake of primitive cultures was associated with lower blood pressure--up to 6 mmHg reduction. But there's clearly more to learn than "cut your salt."
Name that food 13. October 2009 William Davis (30) What common food can:• Cause destructive intestinal damage that, if unrecognized, can lead to disability and death? • Increase blood sugar higher and faster than table sugar?• Trigger an autoimmune inflammatory condition in the thyroid (Hashimoto’s thyroiditis)? • Create intestinal bloating, cramps, and alternating diarrhea and constipation, often labeled irritable bowel syndrome? • Trigger schizophrenia in susceptible individuals? • Cause behavioral outbursts in children with autism?• Cause various inflammatory diseases such as rheumatoid arthritis, ulcerative colitis, dermatitis herpetiformis, systemic lupus, pancreatic destruction, and increase measures of inflammation like c-reactive protein?• Cause unexplained anemia, mood swings, fatigue, fibromyalgia, eczema, and osteoporosis?The food is wheat. Yes, the ubiquitous grain we are urged to eat more and more of by the USDA (8-11 servings per day, according to the USDA food pyramid), American Heart Association, American Dietetic Association, and the American Diabetes Association. Wheat is among the most destructive ingredients in the modern diet, worse than sugar, worse than high-fructose corn syrup, worse than any fat. What other common food can result in such an extensive list of diseases, even death?Celiac disease alone, a severe intestinal inflammatory condition from wheat gluten, affects an estimated 3 million Americans (Celiac Disease Foundation). The medical literature is filled with case reports of deaths from this disease, often after many years of struggle with incapacitating intestinal dysfunction and the sufferer's last days plagued by encephalopathy (brain inflammation). What happens when you remove wheat from the diet? The majority of people quickly shed 20-30 lbs in the first few weeks, selectively lost from the abdomen (what I call “wheat belly”); blood sugar plummets; triglycerides drop up to several hundred milligrams, HDL increases, LDL drops (yes, wheat elimination is a means of achieving marked reduction in LDL cholesterol, especially the small, heart disease-causing variety); c-reactive protein plummets. In addition to this, intestinal complaints improve or disappear, rashes improve, inflammatory conditions like rheumatoid arthritis improve, diabetes can improve or be cured, and behavioral disorders and mood improve.Along with the ill-fated low-fat dietary advice of the last 40 years, the advice to eat plenty of "healthy whole grains" is responsible for untold disease and suffering. Yes, if you start with a fast food and junk diet and replace some of the calories with whole grains, you will be better off. (That was the logic--the Nutritional Syllogism--of the studies that established the benefits of whole grains over processed, "white" grains.) But eliminate wheat grains and health takes a huge leap forward. And, no, there is no such thing as wheat deficiency--B vitamins, insoluble fiber, some protein--can easily be replaced by other foods.
Heart Defects Simplified 12. October 2009 William Davis (0) For as long as I've known him, echocardiography technologist, Ken Heiden, has had a deep fascination with congenital heart disease. Ken has just written a wonderful book on congenital heart disease called Heart Defects Simplified. While this is a bit off-topic for the Heart Scan Blog, I know that there is a serious lack of helpful information for people with congenital heart disease and parents of children with congenital heart defects. So I asked Ken to tell us something about his book. WD: I've reviewed your book and have been thoroughly impressed with the clarity and detail with which you handle a complicated topic. You somehow manage to make it easy to grasp, far more than any other resource I've used in past. Do you feel that your book serves a previously unmet need? KH: This book serves an unmet need in that it presents the complex subject of congenital heart defects in a simplified manner. Most books on this subject are anywhere from 300-1700 pages in length and tend to be written for doctors. Further, most of these books have very few diagrams, and they rely upon their explanations to describe these defects. Heart Defects Simplified is 104 pages in length, describes the most common defects, including surgical repairs, in a two-page format with full-color diagrams on the left and complete descriptions on the right of each chapter. The book is particularly written for sonographers, nurses and parents, but it is valuable for anyone interested in this subject. It is particularly useful in clinical situations because it is convenient to lay out at your side with a coil-bound format and durable pages. Further, there are appendixes which include "Surgical Procedures in Alphabetical Order," "Prevalence of Congenital Heart Disease," "Scanning Protocols for Echocardiographers," "Imaging Tips," a glossary and a worksheet for echocardiographers. WD: I know that many people with loved ones who have congenital heart defects, particularly parents of children with such conditions, are often kept in the dark about the details of the condition. Is your book suitable for the non-technical reader, such as parents? KH: This book is an excellent resource for parents. It is written in language that is understandable by parents as well as technologists and nurses. The full-color diagrams provide invaluable insight into this very complex world. Most importantly, this book attempts to make the subject of congenital heart defects accessible to anyone who wishes to comprehend this subject. WD: I understand that people with congenital heart defects and parents are active participants in online discussion groups. Will your book serve as a resource for people who participate in these groups? KH: This book is not only a resource for sonographers and parents, but the book is accompanied by a blog (HeartDefectsforEveryone.blogspot.com) that attempts to address many of the concerns commonly encountered with congenital heart defects. This blog is a work in progress, but I hope to provide a forum for parents, healthcare personnel, and others to share their questions and concerns about congenital heart disease.
My experience with the omega-3 index 8. October 2009 William Davis (23) I just got back my own results from the Gene Smart laboratory reporting my omega-3 index and omega-6:omega-3 ratio. My results:Omega-3 index: 8.2%Omega-6:omega-3 index: 3.2 to 1Not too bad, but not as good as I'd expected. Hmmm. Although the omega-3 index of 8.2% puts me in the lower risk category for sudden cardiac death, I was hoping for a level of 10% or slightly greater, the level that I believe is more likely to be related to plaque inactivation or reversal. I obtained this level of omega-3 averaging an intake of EPA and DHA of about 2500 mg per day. I was somewhat disappointed by the omega-6:omega-3 index. Although it's clearly better than the American average range of 20:1, it is short of the ideal of 2:1 or even 1:1. Since I purposely avoid omega-6-rich sources like corn oil, vegetable oils, sunflower or safflower oils, I wonder if I've overdone the nuts. The two ways to improve the omega-6:omega-3 ratio are to 1) decrease omega-6, or 2) increase omega-3. I'm going to do both. So I thought I was doing pretty well. But there's clearly room for improvement.Remember: If just reduction of cardiovascular risk is your interest, then a lackadaisical attitude towards these issues might work. But if your interest is elimination of risk and reversal of atherosclerotic plaque, then it pays to go the extra mile. In this case, knowing your omega-3 index and omega-6:omega-3 ratio might tighten up your program.
The Omega-3 Index: The higher, the better? 6. October 2009 William Davis (26) So you take a few fish oil capsules every day and eat fish once or twice a week. What is the blood and tissue level of omega-3 fatty acids generated by your habits? A number of variables enter into the equation. For instance, if you take fish oil capsules, what is the concentration of omega-3 fatty acids? How well are they absorbed? After absorption, how effectively are omega-3 fatty acids incorporated into cell membranes?Even if you take fish oil supplements, it is hard to know just how much you’ve increased blood levels. It is now possible to measure the amount of omega-3 fatty acids in your bloodstream, a value called the omega-3 index. Too little and you might still be at high risk for cardiovascular events. The Omega-3 index and sudden cardiac deathTwo large studies have demonstrated that higher omega-3 blood (the level in red blood cells, or RBCs) levels were associated with reduced likelihood of sudden cardiac death. The risk for sudden cardiac death was 10-fold higher for the lowest omega-3 RBC levels compared to the highest.Harris WS 2008; adapted from Siscovick DS et al 1995 and Albert CM et al 2002(The omega-3 Index was derived from whole blood omega-3 levels, which correlate with RBC omega-3 levels, and are thus “estimated.”)What’s the average omega-3 RBC level for Americans? Most Americans have omega-3 RBC levels in the 2.5-4.0% range, consistent with the tallest bars at the left and associated with greatest risk for sudden cardiac death. People with heart disease can have levels less than 1%. Some authorities propose that this new measure be called the omega-3 index. Subsequent studies have shown that the omega-3 index has greater power to discriminate who will have a heart attack or die from sudden cardiac death better than any other common laboratory measure of coronary risk, including LDL cholesterol, HDL cholesterol, triglycerides, total cholesterol to HDL ratio, homocysteine, and c-reactive protein.Just as hemoglobin A1c offers a 3-month look into blood glucose levels, the omega-3 index reflects your long-term omega-3 intake. The quantity of RBC omega-3s also closely parallels the quantity of omega-3s in heart tissues.What is an ideal omega-3 index?The above studies relating RBC omega-3 levels and sudden cardiac death suggest that a level of 6.3-7.3% is associated with far fewer fatal events?but events are not eliminated at this level. Is there even greater benefit with levels higher than 6.3-7.3%?A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks. This suggests that even higher levels are necessary to prevent non-fatal events. Should we target 10%? 12%? Maybe higher? Any higher and we are toeing the level achieved by the Inuits, the “Eskimoes” of Greenland, northern Canada and Alaska who have been observed to have a low rate of heart disease.What’s your omega-3 index?The appreciation of the importance of omega-3 fatty acids marks one of the greatest health revelations of the last 50 years. We can now measure it.The ability to measure the proportion of omega-3 fatty acids in red blood cells may provide yet another means for all of us to further reduce risk for cardiovascular events.If you are interested in knowing your omega-3 index, we are now making the fingerstick test kits available by going here.
Vitamin D increased my cholesterol 2. October 2009 William Davis (38) A friend told me this story. Her friend, Linda, had added vitamin D to her daily supplements. Because she'd had a vitamin D blood level of 22 ng/ml, she was taking 6000 units per day. However, Linda also had a high cholesterol value with a total cholesterol of 231 mg/dl. After several months on the vitamin D, she had another cholesterol panel. Total cholesterol: 256 mg/dl. "It must have been the vitamin D! So I stopped it right away." Is this true? Does vitamin D raise the level of blood cholesterol? Yes, it does. But it's a good thing. Let me explain. Followers of The Heart Scan Blog know that total cholesterol is really a mix of 3 other factors:Total cholesterol = LDL cholesterol + HDL cholesterol + triglycerides/5This is the Friedewald equation, still used today in over 95% of cholesterol panels. So, by the Friedewald equation, anything that increases LDL, HDL, or triglycerides will increase total cholesterol. One of the spectacular changes that develops over a year of taking vitamin D is that HDL cholesterol skyrockets. While sensitivity to this effect varies (probably on a genetic basis), HDL increases of 10, 20, even 30 mg/dl are common. A starting HDL, for instance, of 45 mg/dl can jump up to 65 or 70 mg/dl, though the effect requires up to a year, sometimes longer. Vitamin D can also reduce triglycerides, though the effect is relatively small, usually no more than 20 mg/dl or so. Likewise, the effect on LDL is minor, with a modest reduction in the small type of LDL. So the dominant effect of vitamin D from a cholesterol standpoint is a substantial increase in HDL. Looking at the equation, you can see that an increase in HDL is accompanied by a commensurate increase in total cholesterol. If HDL goes up 25 mg/dl, total cholesterol goes up 25 mg/dl. So Linda is absolutely correct: Vitamin D increases cholesterol--but it's a good thing that reduces risk for heart disease and is an important part of a coronary plaque-reversal program. This is yet another reason why I advocate elimination of total cholesterol on lipid panels. There is no useful information in the total cholersterol value, only the potential for misinformation.
Nutrtional ignorance is not unique to the U.S. 28. September 2009 William Davis (20) Heart Scan Blog reader from Australia, Michaela, also a mother of a son with a complex congenital heart defect, wrote this series of e-mails to me. (Published with Michaela's permission.) I've been reading the article, Valve disease and Vitamin D from April '07, by Dr William Davis. I'm hoping you may have some information on the topic. I'm hoping someone will have time to help me. I have been supplementing my 15 year old son with Vit D for 4 months but only 1000 (U) per day. I would like to increase the dosage but am not sure if I would do him more harm than good. I have been researching vitamins and supplements on the net for a few months and have been amazed at what I have found. I only wish I had done it years ago. My son has been let down by the Australian Medical Profession and it's a race against time now to keep him well and avoid a heart transplant. My son was born with aortic stenosis and had a valvotomy at 4 weeks of age. This damaged the aortic valve and he had a Ross Repair procedure at aged 3. This left him with a damaged heart muscle and leaking aortic & pulmonary valves. In May '08, his heart grew more enlarged, causing the mitral & tricuspid valves to also leak. I took him to Bangkok in Feb this year where he had 70 million of his own Adult Stem Cells directly injected into his heart muscle with the hope of strengthening the muscle and eventually valve replacement. My son has recovered from the surgery and is once again symptom-free, thanks to the wonderful advice followed by the Author & Cardiologist, Stephen T. Sinatra. I have followed his supplement regime and what a difference! Of course, this won't last while my son's valves continue to leak. My son has also developed secondary hyperparathyroidism, bone thinning and hypothyrodism. Vit D & Calcium have something to do with this I believe. My Australian Doctors have never made mention of any vitamins or supplements .... EVER! Transplant is all they will consider and we are not having it. If you have any info or links to any sites which may be useful to me, could you email them to me? I would be grateful for any help I could get. SincerelyMichaelaI responded to Michaela's e-mail:Hi, Michaela-- Vitamin D is extremely important. Sometimes, hyperparathyroidism and calcium derangements are caused by vitamin D deficiency. You might be able to get help with this from an endocrinologist, since they are the ones who deal with hyperparathyroidism. An endocrinologist might even be familiar with several recent studies that document this phenomenon:Vitamin D therapy in patients with primary hyperparathyroidism and hypovitaminosis DVitamin D deficiency and primary hyperparathyroidismAlso, see the discussions at www.vitamindcouncil.org from Dr. John Cannell.Because of the complexity of your son's health, it might be hazardous to stray too far away from conventional care though you and I know that there are limitations to that perspective. For that reason, I would urge you to press for answers from a knowledgeable endocrinologist. I hope you find the answers you need. William Davis, MDSeveral months later, Michaela provided this update:Hi Dr Davis, I wrote to you back in July regarding my 15 year old son's need for a Heart Transplant through a failed Ross Repair and the possible Vitamin D connection. You sent me some valuable links and I thank you again for that. I just wanted to let you know, I think you have given me the answers. I increased Lee's Vitamin D supplement to 6000U a day and, along with the recommended nutritional supplements of US Cardiologist Dr Stephen T Sinatra, there have been remarkable improvements! Lee also had 70 million of his own Adult Stem Cells injected into his heart in February. As we know, Stem Cell Therapy takes time and Lee was looking like time was quickly running out. I have removed him from the transplant list. He is now reading normal Kidney function, the BNP (Brain Natriuretic Peptide, a measure of heart failure] has dropped by 7000 and his liver size has reduced to where it no longer causes him discomfort. The liver tests show it's still affected but it's function is improving each month. His last Echo was in early July and there had been a reduction in the size of his heart, which is so important. To the Doc's, Lee can't get better, there is only transplant or death so you can imagine the surprise on their faces to see him looking and feeling so well with their tests to back it up. Still, even though it's staring them in the face, they don't want to know about it. They have no interest in what supplements he is on or Stem Cell therapy. God help their other patients. I view them in the waiting room and think of them as lambs to the slaughter. We are not spoiled for choice with Doc's here in Western Australia. I have to take what I can get and there is not many who would take on Lee's case. He was number 1 on the transplant list and a most urgent case. Not many were willing to even look at him with his cardiac history and all I had to help was the arrogant Doc's at the Advanced Heart Failure Unit. They were not at all interested in his secondary hyperparathyroidism. I suppose it didn't matter what else he had compared to his heart problems. Anyway, I'm writing to thank you. Lee would be transplanted or dead now if it wasn't for Dr's like you sharing their knowledge online. I wish I had researched things years ago, Lee might not have sunk so low if I had. I don't know if the transplant can be held off indefinitely, but like I tell Lee, "Stay well. There are amazing people out there doing amazing things, if you can just hang on. The miracle is around the corner." He's so well, you'd have to see him to believe it. But I have 7 kids and Lee is as physically active and as well as the other 6! For how long he can stay like this, I don't know but if his ejection fraction [a measure of left ventricular strength] can keep climbing and his body gets stronger, I have hope for another attempt at valve replacement. I'm still shocked and angry that nutritional supplements have never been mentioned in the 15 years I've been dealing with cardiologists. Surely they know about them. I have read through dozens of reports online of the benefits of them--Why haven't they?! Thank God for the online Doc's such as yourself, the valuable info would never make it out of a Doctor's office in Western Australia! I've had to leave my country for Stem Cell therapy and then implore overseas Doc's for advice and information. What does that say for the Australian Medical Profession? Not a lot! They put him in the position he is in yet don't want to help get him out. I'm so very grateful to you, thank you and God bless. Michaela Note: The above is not meant to be an implicit endorsement of stem cell therapy. This was just part of Michaela's story about her son.
Eat cranberries 24. September 2009 William Davis (17) Most people already know that cranberries are useful for preventing urinary tract infections. Cranberries can also be useful for preventing other sorts of infections, such as dental cavities and stomach ulcers because of cranberry's ability to block bacterial adhesion. Cranberries can also be a useful component of a heart healthy program. Several unique properties of cranberries contribute to various aspects of heart health:• Cranberries are a rich source of pectin--Pectin is a soluble fiber, the sort that binds bile acids in the intestinal tract and naturally reduces LDL cholesterol.• Cranberries are a rich source of polyphenols and flavonoids--Including the wonderfully fascinating anthocyanins, the flavonoids that confer the beautiful red color. Surprisingly, cranberries are richer in polyphenols and flavonoids than blueberries, strawberries, and grapes. Cranberry juice is also rich in these compounds. However, beware of cranberry juice "cocktail," which is diluted with other liquids such as high-fructose corn syrup. Like grapes, cranberries are a source of resveratrol, the polyphenol also found in red wines that some believe is responsible for reduced risk for heart disease and extending life. • Cranberries have high antioxidant activity--Cranberries are among the highest in antioxidant capacity against superoxide radicals, hydrogen peroxide, and hydroxyl radicals, oxidizing factors believed to underlie heart disease, cancer, and aging. Cranberries also reduce the oxidation of LDL cholesterol particles. • Cranberries block uric acid production--Cranberries have the unique ability to block the activity of an enzyme, xanthine oxidase, that converts xanthine to uric acid. Uric acid is believed to add to heart disease risk and is the factor responsible for gout. • Cranberries increase HDL cholesterol--Cranberry juice increases HDL by 3-4 mg/dl. Cranberries are only modest sources of sugars, with 7.19 grams “net” carbohydrates (total carbohydrates minus fiber content) per cup of whole raw cranberries. The best way to eat cranberries is to consume the real thing: eat the whole berry, as in sugar-free cranberry sauce or added to baked dishes like chicken. Second best are dried cranberries. However, be careful of the overly-sweetened dried cranberries that contain added sugar (for a total of 78 grams sugar per cup--far too much). Unsweetened dried cranberries can be purchased, or you can dry them yourself.Cranberry juice is another way to obtain the health benefits of cranberries; the unsweetened juice, while quite tart, is the best with 30.5 grams sugar per 8 oz--so don't drink more than 4 oz at a time. The more common cranberry juice “cocktails” are generally too sugary and/or too dilute for full health benefit. The cranberry harvest season in Wisconsin, Michigan, Oregon, Massachusetts, and New Jersey is just getting underway, so we should be seeing fresh cranberries on store shelves or farmers' markets any day now.
Procedures 'R Us 23. September 2009 William Davis (20) Kay came to the office for an opinion. Over the past 8 months, she'd received a stent to the left anterior descending coronary artery and, during a separate procedure, a stent to the left subclavian artery. "My cardiologist was very capable doing procedures. But when I asked, 'What do I do now?' he barely said a word and handed me a presciption for Crestor." This kind of incredible neglect is the norm: Write a prescription for statin drug, delegate dietary advice to the hospital dietitian who advocates a heart disease-causing low-fat diet, followed by hospital discharge. You are expected to report any recurrent symptoms (which are inevitable), at which point you might "qualify" for another procedure. It would be malpractice if it were not the prevailing standard in the community. Yes, the prevailing standard is neglect--neglect to identify, quantify, and correct all the identifiable causes of heart disease; neglect to discuss the nutritional methods that actually correct the abnormal patterns that cause heart disease; neglect to discuss nutritional supplements or medications beyond statins that further reduce heart disease risk and "need" for more procedures. In other words, the prevailing community standard is to stent, bypass, prescribe statin. It is not to understand why the disease occurred in the first place, correct the causes and minimize or eliminate any future danger or need for procedures. I see consultation after consultation involving stories just like Kay's. People are frightened and they sense intuitively that nobody raised the question of why they have a potentially fatal disease. Don't allow yourself to fall victim to this incredibly neglectful mode of practice, the one that has enriched hospitals, the drug industry, many cardiologists, but does little to address the actual disease.
