Santa Claus is alive . . . and works for the drug industry 12. December 2008 William Davis (7) Maybe your teenagers no longer believe in Santa Claus, but I assure you: Not only is he alive, I believe that we have evidence that he works for the drug industry!Psshaww! you say. Yet another rant from that kook, Davis. Who can he pick on next? What other imagined "conspiracies" can he uncover?Let me recount the evidence and I'll let you decide how damning it all is:--Christmas is a culture of excess, overeating, celebration: Cookies, candy canes, pie, chocolate, egg nog, more cookies . . . A virtual wheat and sugar frenzy! --Wheat and sugars make us diabetic! --What does a diabetic look like? How about big protuberant abdomen, florid cheeks, baggy eyes (from sleep apnea)? The red outfit and beard is optional, of course. Could you think of a better representation of what happens to a person when they eat goodies all the time? I therefore submit that Santa Claus is at the root of a campaign to cultivate diabetes! Diabetes: a growth industry that is raking in billions of dollars for the drug companies! I'd bet that Mr. Claus would agree with the dietary advice dispensed by the folks at the American Diabetes Association website:A place to start is at about 45-60 grams of carbohydrate at a meal. You may need more or less carbohydrate at meals depending on how you manage your diabetes. Eat more carbohydrates, get fatter in the abdomen, require more medication to keep sugar low. Then start over: eat more carbohydrates, get fatter, more medicines. Kaching!"You may need more?" Personally, I'd be rendered comatose and helpless if I indulged in such carbohydrate gluttony. If Mr. Claus were, instead, interested in our health and keeping us non-diabetic, Christmas would be a time for pistachios, almonds, dark chocolates, and tea. You want health advice? Don't ask Santa Claus!
Another case of aortic valve disease reduced with vitamin D 12. December 2008 William Davis (8) I watched Seth's aortic valve deteriorate over a two year period. I was first consulted in 2004 to offer an opinion on Seth's heart scan score of 779 and flagrantly abnormal cholesterol patterns, including triglycerides in the 400 mg/dl range. But I heard a murmur, as well, a murmur of a leaky aortic valve, "aortic valve insufficiency." Over the next two years, I watched Seth's aortic valve worsen, going from mild leakiness to severe. In 2006-2007, I tiptoed into vitamin D replacement and asked Seth to add some vitamin D. Time passed and Seth's aortic valve got progressively worse. Over the past year, However, he's maintained a truly healthy level of vitamin D, with blood levels consistently in the 60-70 ng/ml range. While Seth's last echocardiogram showed a severely leaky aortic valve, the most recent echo showed mild leakiness ("mild aortic insufficiency")--a dramatic reduction. I continue to see this in many, though not all, patients with aortic valve disease. Though I've more frequently witnessed either stalled progression or reversal of aortic valve stenosis (stiffness), I've now seen a handful of people with aortic valve leakiness (insufficiency) also reverse. I've posted about this peculiar phenomenon previously:Aortic valve disease and vitamin DMore on aortic valve disease and vitamin D Prior to vitamin D, I had NEVER witnessed any aortic valve disease stop or reverse. A formal trial at some point would be invaluable.
Track Your Plaque Program Data Tracking Tools 7. December 2008 William Davis (3) At last: After talking about the new Track Your Plaque community tools for the last year, our data tracking software is now available!Track Your Plaque is, admittedly, somewhat data-intensive. The basic concept relies on the fact that we track heart scan scores, cholesterol values, lipoprotein values like percent small LDL and Lp(a), vitamin D blood levels, intake of omega-3 fatty acids, etc. Our new data tracking tools will help Members track their data over time. Even more interesting, you can allow other Members (not required) to view your data for comments and feedback. You can also view the program data of other Members (if they choose to make their data "public") to learn how they are going about stopping and reversing their coronary plaque. In other words, our graphic data tracking tools are yet another way we are using to acquire a collective wisdom on how to put a stop to coronary heart disease, heart attack, and perverse "let's make money with heart procedures" hospital solutions. One of the aspects that helps make this work is the sharing of data. So far, the people who have begun to enter their data have all made their information "public." It's not truly "public," but viewable only by other Track Your Plaque Members. Also, Members can, in effect, anonymize their data simply by using a nickname, e.g., heartprotection or hearthawk. The data tracking tools are in beta-test version, so there are bound to be a few glitches. But we're eager to hear from our Members' experiences on how to improve these tools. Report any problems or make your suggestions on the Track Your Plaque Member Forum--Technical Support.
Yet another reason to avoid fructose 6. December 2008 William Davis (5) Have you seen the Corn Refiners Association commercial campaigns to educate the American public on the safety of fructose? If you haven't, you can view these interesting specimens on You Tube:"Get the facts--You're in for a sweet surprise: Fructose is safe in moderation!"Two MomsTwo loversBeyond the fact that fructose stimulates liver production of glycerol, which thereby increases liver VLDL production and raises blood levels of triglycerides; likely stimulates appetite; increases cholesterol levels; fructose has also been clearly implicated in increasing blood levels of uric acid. Uric acid is the substance that, in some people, precipitates in joints and causes gout, the painful inflammatory arthritis that has been increasing in prevalence over the last four decades since the introduction of fructose in 1967. While blood levels of uric acid in the early part of the 20th century averaged 3.5 mg/dl, more recent population assessments have averaged 6.0 mg/dl or higher. (Non-human mammals who don't eat processed foods, drink fruit drinks or beer, and don't eat candy have uric acid levels of <2.0 mg/dl.)Uric acid is looking like it may prove to be an important risk factor for coronary disease and atherosclerotic plaque. It is no news that people with higher blood levels of uric acid are more likely to experience adverse cardiovascular events like heart attack. People with features of the metabolic syndrome also have higher uric acid blood levels; the more characteristics they have, the higher the uric acid level. However, the prevailing view has been that uric acid is simply an accompaniment of these processes, but not causal. However, more recent observations suggest that increased levels of uric acid may instead be a cause of metabolic syndrome and high blood pressure.Increased blood levels of uric acid have been shown to:--Increase blood pressure--Induce kidney damage (even in the absence of uric acid kidney stones)--Antagonize insulin responsesA diagnosis of gout is not required to experience all of the adverse phenomena associated with uric acid. (For not entirely clear reasons, some people, perhaps based on pH or other factors, are more prone to trigger crystallization of uric acid in joints, similar to the phenomena of sugar crystallization when making rock candy.) Which brings us back to fructose, a sweetener that clearly substantially increases uric acid levels. I suppose that the mothers and lovers in the Corn Refiners' commercials are right to a degree: Our kids will survive, as will you and I, despite increases in triglycerides, enhanced diabetic tendencies, amplified appetites, and increased uric acid due to fructose in our diet. We will also likely survive despite being 100 lbs overweight, partly due to the effects of fructose. But if long-term health is your desire for you and your family, fructose has no role whatsoever to play. Interestingly, the obviously expensive and slick ad campaigns from the Corn Refiners' videos have triggered some helpful video counterarguments:High-fructose corn syrupConspiracy for Fat AmericaHigh-fructose corn syrup truthA full discussion of uric acid, the scientific data behind uric acid as a coronary risk factor, and the nutritional means to reduce uric acid will be the topic of a thorough discussion in an upcoming Special Report on the Track Your Plaque website.
Free the Animal 4. December 2008 William Davis (10) Richard Nikoley from the Free the Animal Blog contributes this informative comment:'Bout 18 months ago, I was at 230 (5'10) and looked awful. I was on Omeprezole for years for gastric reflux, a variety of prescription meds since early 20s for seasonal sinus allergies, culminating finally in the daily, year round squirts of Flonase-esque sprays (the best for control without noticeable side-effects), and finally, Levothroid for about the last 7 years or so, as I had elevated TSH (around 9ish).My BP was regularly 145-160 / 95-110.I decided to get busy. I modified diet somewhat, cutting lots of junk carbs, and began working out -- brief, intense, heavy twice per week. BP began coming down immediately, such that within only a couple of weeks I was borderline rather than full blown high. Then after about six months, a year ago, I went to full blown low-carb, high fat, cutting out all grains, sugar, veg oils, etc, and replacing with animal fats, coconut, olive oil. You know the drill. Then, first of the year I felt great and simply stopped all meds, including the thyroid. I also began intermittent fasting, twice per week, and for a twist, I always do my weight lifting in some degree of fast, even as much as 30 hours.That's when the weight really started pouring off. Take a look:http://www.freetheanimal.com/root/2008/09/periodic-photo-progress-update.htmlhttp://www.freetheanimal.com/root/2008/08/faceoff.htmlIn July I figured it's about time for a physical. Here's the lipid panel, demonstrating am HDL of 106 and Try of 47, great ratios all around:http://www.freetheanimal.com/root/2008/07/lipid-pannel.htmlHowever, my TSH was even higher -- 16ish. It seems odd that I was able to lose 40-50 pounds of fat (10-15 pounds of lean gain for a 30 pound net loss at that time -- now an additional 10 pounds net loss).One disclosure is that I was drinking too much, almost daily, and quite a bit (gotta save some vices...). Anyway, I'm at the point now where I want to drill down. I know I need to see an endocrinologist and have T3 and T4 looked at, but in advance, I wanted to see if the recent changes I've made could make a difference:1. Stopped all alcohol.2. Stopped most dairy, except ghee and heavy cream, and cheese is now used as a "spice," i.e., tiny quantities -- no more milk.3. 6,000 IU Vit D per day.4. 3 grams salmon oil, 2 grams cod liver oil.5. Vit K2 Menatetrenone (MK-4) -- side story: getting off grains reversed gum disease for which I have had two surgeries, then supplementing the K2 DISSOLVED calculus on my teeth within days -- hygienist and dentist are dumbfounded. Stephan (Whole Health Source), who comments here, has an amazing series on K2.If you view his photos, you'll appreciate just how far he has come.Overall, Richard's program is wonderful and his pictures clearly display his success. However, Richard, thyroid function is indeed a problem, a problem that needs to be fixed ASAP. Remember, low thyroid function used to be diagnosed at autopsy at which time the coronary arteries and other arteries of the body were found to be packed solid with atherosclerotic plaque, even in young people. I'd recommend:1) Consider 200 mcg Iodine per day from kelp if you do not use iodized salt. 2) Seeing your doctor right away for thyroid replacement, hopefully with consideration of your T3 status. 3) A heart scan--Not to lead to procedures, but something for you to track over time as your program improves and thyroid function is restored.Beyond this, keep up the great work. Great blog, too!
Low Thyroid and Plaque 3. December 2008 Toggle navigation Home Blog Home Archive Join Now Log in What's that in your mouth? 7. January 2010 William Davis (17) Fat = triglyceridesIn other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.Thanks to cartoonist Eli Stein, who has generously allowed me to reprint his artwork on these pages. Mr. Stein has published his work in dozens of magazines and newspapers, including the Wall Street Journal, Barron's, and Good Housekeeping. More of his work can be found at Eli Stein Cartoons. De Novo Lipo-what? 5. January 2010 William Davis (16) Humans have limited capacity to store carbohydrates. Beyond the glucose and glycogen in our blood and tissues, we have relatively little carbohydrate to draw from in time of energy need. That's why long-distance runners and triathletes have to carry sugar sources to keep blood sugar from plummeting.Fat, of course, is different. We have virtually unlimited capacity to store energy as fat.Because we have limited carbohydrate storage capacity, what can the body do with the excessive quantities of carbohydrates that Americans ingest? What becomes of a bagel for breakfast, wheat crackers for snacks, a whole wheat sandwich for lunch, pretzels, and whole wheat pasta that many people eat every day, not to mention the chips, soft drinks, and juices?Excess carbohydrates are diverted to an interesting metabolic pathway called de novo lipogenesis (DNL). This refers to the liver's ability to make triglycerides from excessive carbohydrates in the diet. Triglycerides are packaged for release into the blood as VLDL. VLDL, in turn, interacts with other lipoproteins, creating small LDL particles, reduced HDL and smaller, less protective HDL. High VLDL will be measured on a standard cholesterol panel as higher triglycerides.A University of California (Berkeley, San Francisco) group has done much of the work describing DNL.A diet weighed towards carbohydrates, especially if 50% or greater calories are carbohydrate, is sufficient to provoke plenty of DNL, even in slender people. DNL is a big part of the reason why low-fat (and, thereby, high-carbohydrate) diets result in higher triglycerides. DNL really gets turned on many-fold if the carbohydrates are "simple," rather than "complex."Overweight people, however, can demonstrate five-fold greater DNL even with lesser quantities of carbohydrate intake (e.g., 40% fat, 46% carbohydrate, 14% protein):From Schwarz et al 2003. Mean (± SEM) fractional de novo lipogenesis in lean normoinsulinemic (NI), obese NI, and obese hyperinsulinemic (HI) subjects after 5 d of consuming a high-fat, low-carbohydrate diet and in different lean NI and obese HI subjects after 5 d of consuming a low-fat, high-carbohydrate diet. Values with different superscript letters are significantly different. Excessive carbohydrates, a la standard low-fat diets, are good for nobody. The concept of de novo lipogenesis fills in a theoretical hole that now explains why people who eat carbohydrates have higher triglycerides, VLDL, and, eventually, insulin resistance and diabetes. Gretchen's postprandial diet experiment II 3. January 2010 William Davis (37) I previously posted Gretchen's postprandial diet experiment, in which she consumed a low-fat diet for a day, followed by a low-carbohydrate diet for a day. Grethen monitored blood glucose and triglycerides with fingerstick checks. (Blood glucose can be checked on any widely available glucose monitor; triglycerides can be monitored with the Cardiochek device.)Let's now discuss what happened. On the low-carb, high-fat day, there was an initial surge in triglycerides to 250 mg/dl late morning, followed by a secondary peak several hours following dinner. Because fat is mostly triglycerides, Gretchen's high-fat (sausage, bacon, butter, whole-fat yogurt) breakfast provided a large quantity of triglycerides that needed to be absorbed. This generally occurs over approximately 6 hours, varying depending on body weight, how accustomed you are to fat, activity level during the day, the kind of fat in the meal. The high content of saturated fat in Gretchen's high-fat breakfast likely caused the somewhat slower drop in triglycerides over approximately 7 1/2 hours. As Gretchen herself had noted, triglycerides the following day were lower, a typical low-carb response. Blood sugar throughout showed only minor variation, with only small postprandial increases. Thus, Gretchen experienced what we'd expect with a low-carb, high-fat diet: an initial high surge in triglycerides, followed by a decline in fasting levels, while blood sugar shows a normal contour. Now, the more confusing low-fat experience: Blood glucose makes a striking peak at 200 mg/dl after the low-fat breakfast of pasta and rice, in contrast to the low-carb breakfast. Triglycerides behaved very differently from the low-carb experiment: While there was no initial postprandial surge, there was a late surge developing 6-24 hours later. The late surge continued into the next day, with fasting levels the following morning (210 mg/dl) exceeding the starting triglyceride level (60 mg/dl). The one potentially confusing aspect of all this is Gretchen's late rise in triglycerides on the low-fat diet. This phenomenon is due to something called de novo lipogenesis, or the liver's conversion of carbohydrates to triglycerides that occurs when an excessive carbohydrate load comes through diet. Because the human body cannot store anything beyond a minor quantity of carbohydrates (as glucose and glycogen), carbohydrates are converted to fats. Another factor causing the late triglyceride increase is insulin resistance, given the high blood sugar response. When insulin resistance is present, the activity of the enzyme, lipoprotein lipase, is reduced. Less lipoprotein lipase activity allows slower VLDL degradation, allowing VLDL (and thereby triglycerides contained in VLDL) to "stack up" in the blood. Thus, the higher triglycerides late after eating and into the next morning. One issue to be aware of: Acute responses can differ from chronic responses. In other words, had Gretchen had the luxury (and time and money) to conduct the experiment over, say, 4 weeks, rather than a single day, there would be somewhat different responses. The best data on this come from Dr. Jeff Volek of the University of Connecticut, in which 4 weeks of low-carbohydrate eating modify fasting and postprandial responses over time. Several conclusions can be made from Gretchen's experience:1) Low-carb, high-fat acutely generates extravagant postprandial triglyceride responses.2) Low-fat causes a late triglyceride surge and higher fasting triglycerides. 3) Low-fat leads to high blood sugars and, by implication, diabetes. Both the low-carb and the low-fat responses are undesirable, both leading to increased risk for heart disease. Which is worse? I believe that low-fat is more destructive, since it leads over time to both high triglycerides and diabetes, while low-carb/high-fat only leads to postprandial triglyceride surges, at least acutely. How to best balance the responses to reduce risk for heart disease? That's a discussion for future. Again, my thanks to Gretchen and the substantial amount of effort that went into generating these numbers. More of Gretchens' own writing can be found on her blogs:http://wildlyfluctuating.blogspot.com http://www.healthcentral.com/diabetes/c/5068 A wheat-free 2010 2. January 2010 William Davis (22) A Heart Scan Blog reader sent this fascinating description of his wheat-free adventure. Whenever I discuss this notion of going wheat-free and the incredible health effects that develop, I invariably receive comments or emails saying something like "I eat wheat and feel fine. That can't be true." The problem is that not everybody needs to go wheat-free. 20-30% of people can include wheat in their diet and suffer little more than weight gain, some not at all. But stories like Michael's (below) are commonplace in my experience. I've had many patients who, at first, refused to believe that wheat exposure might be the underlying cause for health struggles. But they finally give it a try and find that rashes, arthritis, acid reflux, irritable bowel symptoms, mood swings, anger, etc. are miraculously improved or gone. Anyway, hear what Michael has to tell us: Dr. Davis, I want to thank you. I was browsing the web a while back and happened to stumble upon your blog post about wheat belly. The first thing that caught my attention was that I thought you had somehow gotten a photograph of me. The young man you posted an image of looked exactly like me. So I read what you had to say. After reading, I thought "Four weeks isn’t so bad. I think I can handle this." It has now been nine weeks and all I can say is that I am completely amazed. Let me say first that twice in the past twenty years I have been tested for allergies. The first time I was tested I showed a slight reaction to Timothy Grass, but not enough to cause me any problems. The second testing I did not show a reaction to anything. So, I have always assumed that my chronic sinus problem were due to sensitivities to environmental pollutions. Now I am not so sure. I would like to list for you everything that has happened to me since I eliminated wheat from my diet. 1. I have lost a total of 12 pounds in the last 9 weeks.2. I have lost 1 ¼ inches of belly fat3. I have lost a tremendous amount of fat from my neck.4. My entire life I have had problems with oily hair. I could wash my hair and three hours later I looked as if I hadn’t washed in a week. Now my hair stays clean and soft for two to three days without shampoo.5. My hair was always flat and stringy. Now it has lots of body.6. I used to have thick layers of dry skin on my scalp. It would come loose in chunks as large as a fingernail. That dry scalp is gone.7. I used to have dry flaky skin that seemed to secrete oil. That no longer happens. My skin is now soft and smooth.8. I have lived with bad acne for at least 35 years. Now it is hard to find a pimple on my body.9. I have always had to fight dehydration. That is no longer a problem.10. I used to drink two large cups of coffee every morning just to be able to function. I now have enough energy that I have eliminated caffeine from my diet.11. I sleep more soundly than ever before and my dreams are clear and vivid.12. My thought processes are more active and clear than they have ever been. 13. My chronic sinus issue is now a thing of the past.14. I used to have problems with getting the “shakes” if I had gone more than a couple of hours without eating. It was as if I was suffering from low blood sugar. I would even be afraid that I would pass out. Now all I feel is hunger. I can go all day without eating and never feel in danger of losing consciousness. Today is Thursday. This past Monday my wife and I were eating out and I ordered a burger without a bun. What I didn’t realize was that the burger would arrive covered in onion rings. I knocked the mountain of onion rings onto the plate but there were still a couple that were embedded in the cheese. I decided, what the hell, a couple of onion rings shouldn’t make that much of a difference. I will not make that mistake again anytime soon. Within 30 minutes I felt like there was a steel spike going through my left eye socket. I don’t remember ever being in that much pain. My sinuses were exploding. This morning, as I write this, I still feel the vestiges of that pain. Just enough that I know it is there. But after two and a half days, I am at least able to function again. I owe you a debt of gratitude. You may have just saved my life. In the very least you have given me the means to improve my life in ways that I never thought possible. Thank you so much,Michael B.Now, if wheat exposure can do that in Michael, what damage can it do in other people? Personally, I previously experienced many of the same symptoms that Michael suffered, all gone with wheat elimination. My advice: If you have any inkling that you might have a wheat sensitivity, make a New Year's resolution to stay wheat-free for 4 weeks and see whether you can feel any difference. Not everybody will, but many will be telling us about the dramatic health turnarounds they experienced. Lipoprotein lipase and you 30. December 2009 William Davis (0) Lipoprotein lipase can make the difference between having heart disease and not having it. Having sky-high triglycerides or normal triglycerides. It can mean dinner hanging around for over 12 hours in the bloodstream, rather than the usual 4-6 hours. If you take niacin, you must exercise 30. December 2009 William Davis (23) We use a lot of niacin in the Track Your Plaque program. Niacin:--Increases HDL and shifts HDL towards the large, protective fraction--Reduces small LDL--In fact, niacin is the best treatment we have to reduce small LDL after wheat elimination and carbohydrate reduction.--Reduces fasting and postprandial (after-eating) triglycerides--Reduces heart attack risk by 20-28%--even as a sole agent. But . . . niacin also triggers higher blood sugar because it partially blocks the effects of insulin (insulin "resistance").While the net effect of niacin remains positive, the provocation of insulin resistance is not such a good thing. Can it be minimized or eliminated? Yes, through exercise. Here's one interesting observation in obese (BMI 34.0), sedentary men given placebo, exercise, niacin (1500 mg Niaspan, once per day), or niacin + exercise: From Plaisance et al 2008. Blood was drawn following a high-fat meal challenge. (Yes, a high-fat challenge, not a carbohydrate challenge. In this study, there were only 17 grams carbohydrates in the test meal, but 100 grams fat. More on this in future.) Exercise consisted of walking for 50 minutes at a moderate pace one hour prior to the meal challenge.You can see from the graph that exercise partially corrected the increased insulin level provoked by niacin. Judging from this and other studies, exercise can help minimize the insulin-blocking effects of niacin. It doesn't take much, just moderate exercise for at least 30 minutes. Adequate sleep can also help, since sleep deprivation is a potent trigger for insulin resistance, only worsened in the presence of niacin. Vitamin D supplementation to achieve desirable blood levels (which I define as 60-70 ng/ml) is also an effective means to minimize this effect. To track small LDL, track blood sugar 24. December 2009 William Davis (28) Here's a trick I learned after years of fussing over people's small LDL. To gain better control over small LDL, follow blood sugars (blood glucose). When you think about it, all the foods that trigger increases in blood sugar also trigger small LDL. Carbohydrates, in general, are the most potent triggers of small LDL. The most offensive among the carbohydrates: foods made with wheat. After wheat, there's foods made with cornstarch, sucrose (table sugar), and the broad categories of "other" carbohydrates, such as oats, barley, quinoa, sorghum, bulghur, etc. Assessing small LDL requires a full lipoprotein assessment in which small LDL particles are measured (NMR, VAP, GGE). Not the easiest thing to do in the comfort of your kitchen. However, you can easily and now cheaply check your blood sugar. Because blood sugar parallels small LDL, checking blood sugar can provide insight into how you respond to various foods and know whether glucose/small LDL have been triggered. Here's how I suggest patients to do it:1) Purchase an inexpensive blood glucose monitor at a discounter like Walmart or Walgreen's. You can buy them now for about $10. They're even sometimes free with promotional offers. You will also need to purchase lancets and test strips. 2) With a meal in question, check a blood sugar just prior to the meal, then again 60 minutes after finishing the meal. Say, for example, your pre-meal blood sugar is 102 mg/dl. You eat your meal, check it 60 minutes after finishing. Ideally, the postprandial (after-meal) blood sugar is no more than 102 mg/dl, i.e., no higher than pre-meal. Perhaps you're skeptical that oatmeal in skim milk with walnuts and raisins will do any damage. So you perform this routine with your breakfast. Blood sugar beforehand: 100 mg/dl. Blood sugar 1 hour post: 163 mg/dl--Uh oh, not good for you. And small LDL will be triggered. This approach is not perfect. It will not, for example, identify "stealth" triggers of blood sugar and small LDL like pasta, for the same reasons that pasta has a misleadingly low glycemic index: sugars are released slowly and not fully evident with the one-hour blood sugar. Nonetheless, for most foods and meals, tracking your one-hour postprandial blood sugar can provide important insight into your individual susceptibility to sugar and small LDL-triggering effects. C-reactive protein: Fiction from the drug industry? 21. December 2009 William Davis (0) C-reactive protein (CRP) is the liver product of inflammatory responses anywhere in the body. If there's an inflamed left knee, CRP will be increased. If viral bronchitis is making you cough, then CRP will be increased. The argument put forward by the drug industry is that, because CRP indicates underlying inflammation, very low-grade levels that can be measured in the absence of overt inflammation like the sore knee or bronchitis is associated with increased risk for cardiovascular events. There are now many studies that conclusively demonstrate that, the higher the CRP, the greater the cardiovascular risk. Naturally, any marker of risk is followed by the inevitable study: Do statin drugs reduce the excess cardiovascular risk of excessive CRP? And, yes, indeed they do. My statin-crazed colleagues rave about the so-called "pleiotropic," or non-lipid, effects of statins. CRP reduction and the reduction of risk associated with CRP result with statin treatment. But is life really statin vs. placebo, as most statin trials are constructed? Are there strategies that can outdo statins like Crestor for reduction of CRP? Watch your fish oil labels 17. December 2009 William Davis (36) A quick quiz: How much omega-3 fatty acids, EPA + DHA, are in each capsule of fish oil with the composition shown on the label below:If you said 1340 mg (894 mg + 446 mg), sorry, but you're wrong. There are 670 mg EPA + DHA per capsule. Did you notice that the composition, or "Supplement Facts," lists the contents of two capsules? Rather than the usual one capsule contents, this product label lists two capsules. I don't know why some manufacturers or distributors do this. However, I have seen many people tripped up by this kind of labeling, taking half the omega-3 fatty acids they thought they were taking. This can be important when you are trying to obtain a specific dose of EPA + DHA to reduce triglycerides, reduce Lp(a), control abnormal heart rhythms, reduce bipolar mood swings, or other important effects. I liken this to pulling up to a gas station where the sign says gasoline for $1.25. Wow! Can't beat that! You then find out that it's really $1.25 for a half-gallon, or $2.50 a gallon. In truth, the labeling is accurate; it's just very easy to not notice the two capsule composition. Why do I need a prescription for Olava? 16. December 2009 William Davis (0) Imagine this:What is OLAVA?Olava is prescription olive oil. It is the purest, highest concentration of olive oil available. Why Do I Need a Prescription for OLAVA?Studies show that olive oil contains essential fatty acids, "good" fats that:--Contain natural compounds your body needs for good health but can't produce on its own.--Has antioxidants that may provide protection from heart disease.So, it is common for people to ask why they need a prescription for OLAVA if it is made from a natural ingredient--olive oil. It's time to get the facts about OLAVA. Learn why OLAVA is different from olive oil you can buy at a store.
What's that in your mouth? 7. January 2010 William Davis (17) Fat = triglyceridesIn other words, eat fat, whether it's saturated, hydrogenated, polyunsaturated, or monounsaturated, and blood levels of triglycerides will go up over the next 6 hours. This remains true if there are carbohydrates in the meal, or if there are NO carbohydrates in the meal. It also remains true if you chronically consume fats.While fats are the primary determinant of postprandial (after-eating) triglycerides, carbohydrates are the primary determinant of fasting triglycerides.So, if your triglycerides are high on a fasting cholesterol (lipid) panel, it's most likely because you overconsume carbohydrates.Thanks to cartoonist Eli Stein, who has generously allowed me to reprint his artwork on these pages. Mr. Stein has published his work in dozens of magazines and newspapers, including the Wall Street Journal, Barron's, and Good Housekeeping. More of his work can be found at Eli Stein Cartoons.

High VLDL will be measured on a standard cholesterol panel as higher triglycerides.A University of California (Berkeley, San Francisco) group has done much of the work describing DNL.A diet weighed towards carbohydrates, especially if 50% or greater calories are carbohydrate, is sufficient to provoke plenty of DNL, even in slender people. DNL is a big part of the reason why low-fat (and, thereby, high-carbohydrate) diets result in higher triglycerides. DNL really gets turned on many-fold if the carbohydrates are "simple," rather than "complex."Overweight people, however, can demonstrate five-fold greater DNL even with lesser quantities of carbohydrate intake (e.g., 40% fat, 46% carbohydrate, 14% protein):From Schwarz et al 2003. Mean (± SEM) fractional de novo lipogenesis in lean normoinsulinemic (NI), obese NI, and obese hyperinsulinemic (HI) subjects after 5 d of consuming a high-fat, low-carbohydrate diet and in different lean NI and obese HI subjects after 5 d of consuming a low-fat, high-carbohydrate diet. Values with different superscript letters are significantly different. Excessive carbohydrates, a la standard low-fat diets, are good for nobody. The concept of de novo lipogenesis fills in a theoretical hole that now explains why people who eat carbohydrates have higher triglycerides, VLDL, and, eventually, insulin resistance and diabetes.
Gretchen's postprandial diet experiment II 3. January 2010 William Davis (37) I previously posted Gretchen's postprandial diet experiment, in which she consumed a low-fat diet for a day, followed by a low-carbohydrate diet for a day. Grethen monitored blood glucose and triglycerides with fingerstick checks. (Blood glucose can be checked on any widely available glucose monitor; triglycerides can be monitored with the Cardiochek device.)Let's now discuss what happened. On the low-carb, high-fat day, there was an initial surge in triglycerides to 250 mg/dl late morning, followed by a secondary peak several hours following dinner. Because fat is mostly triglycerides, Gretchen's high-fat (sausage, bacon, butter, whole-fat yogurt) breakfast provided a large quantity of triglycerides that needed to be absorbed. This generally occurs over approximately 6 hours, varying depending on body weight, how accustomed you are to fat, activity level during the day, the kind of fat in the meal. The high content of saturated fat in Gretchen's high-fat breakfast likely caused the somewhat slower drop in triglycerides over approximately 7 1/2 hours. As Gretchen herself had noted, triglycerides the following day were lower, a typical low-carb response. Blood sugar throughout showed only minor variation, with only small postprandial increases. Thus, Gretchen experienced what we'd expect with a low-carb, high-fat diet: an initial high surge in triglycerides, followed by a decline in fasting levels, while blood sugar shows a normal contour. Now, the more confusing low-fat experience: Blood glucose makes a striking peak at 200 mg/dl after the low-fat breakfast of pasta and rice, in contrast to the low-carb breakfast. Triglycerides behaved very differently from the low-carb experiment: While there was no initial postprandial surge, there was a late surge developing 6-24 hours later. The late surge continued into the next day, with fasting levels the following morning (210 mg/dl) exceeding the starting triglyceride level (60 mg/dl). The one potentially confusing aspect of all this is Gretchen's late rise in triglycerides on the low-fat diet. This phenomenon is due to something called de novo lipogenesis, or the liver's conversion of carbohydrates to triglycerides that occurs when an excessive carbohydrate load comes through diet. Because the human body cannot store anything beyond a minor quantity of carbohydrates (as glucose and glycogen), carbohydrates are converted to fats. Another factor causing the late triglyceride increase is insulin resistance, given the high blood sugar response. When insulin resistance is present, the activity of the enzyme, lipoprotein lipase, is reduced. Less lipoprotein lipase activity allows slower VLDL degradation, allowing VLDL (and thereby triglycerides contained in VLDL) to "stack up" in the blood. Thus, the higher triglycerides late after eating and into the next morning. One issue to be aware of: Acute responses can differ from chronic responses. In other words, had Gretchen had the luxury (and time and money) to conduct the experiment over, say, 4 weeks, rather than a single day, there would be somewhat different responses. The best data on this come from Dr. Jeff Volek of the University of Connecticut, in which 4 weeks of low-carbohydrate eating modify fasting and postprandial responses over time. Several conclusions can be made from Gretchen's experience:1) Low-carb, high-fat acutely generates extravagant postprandial triglyceride responses.2) Low-fat causes a late triglyceride surge and higher fasting triglycerides. 3) Low-fat leads to high blood sugars and, by implication, diabetes. Both the low-carb and the low-fat responses are undesirable, both leading to increased risk for heart disease. Which is worse? I believe that low-fat is more destructive, since it leads over time to both high triglycerides and diabetes, while low-carb/high-fat only leads to postprandial triglyceride surges, at least acutely. How to best balance the responses to reduce risk for heart disease? That's a discussion for future. Again, my thanks to Gretchen and the substantial amount of effort that went into generating these numbers.

A wheat-free 2010 2. January 2010 William Davis (22) A Heart Scan Blog reader sent this fascinating description of his wheat-free adventure. Whenever I discuss this notion of going wheat-free and the incredible health effects that develop, I invariably receive comments or emails saying something like "I eat wheat and feel fine. That can't be true." The problem is that not everybody needs to go wheat-free. 20-30% of people can include wheat in their diet and suffer little more than weight gain, some not at all. But stories like Michael's (below) are commonplace in my experience. I've had many patients who, at first, refused to believe that wheat exposure might be the underlying cause for health struggles. But they finally give it a try and find that rashes, arthritis, acid reflux, irritable bowel symptoms, mood swings, anger, etc. are miraculously improved or gone. Anyway, hear what Michael has to tell us: Dr. Davis, I want to thank you. I was browsing the web a while back and happened to stumble upon your blog post about wheat belly. The first thing that caught my attention was that I thought you had somehow gotten a photograph of me. The young man you posted an image of looked exactly like me. So I read what you had to say. After reading, I thought "Four weeks isn’t so bad. I think I can handle this." It has now been nine weeks and all I can say is that I am completely amazed. Let me say first that twice in the past twenty years I have been tested for allergies. The first time I was tested I showed a slight reaction to Timothy Grass, but not enough to cause me any problems. The second testing I did not show a reaction to anything. So, I have always assumed that my chronic sinus problem were due to sensitivities to environmental pollutions. Now I am not so sure. I would like to list for you everything that has happened to me since I eliminated wheat from my diet. 1. I have lost a total of 12 pounds in the last 9 weeks.2. I have lost 1 ¼ inches of belly fat3. I have lost a tremendous amount of fat from my neck.4. My entire life I have had problems with oily hair. I could wash my hair and three hours later I looked as if I hadn’t washed in a week. Now my hair stays clean and soft for two to three days without shampoo.5. My hair was always flat and stringy. Now it has lots of body.6. I used to have thick layers of dry skin on my scalp. It would come loose in chunks as large as a fingernail. That dry scalp is gone.7. I used to have dry flaky skin that seemed to secrete oil. That no longer happens. My skin is now soft and smooth.8. I have lived with bad acne for at least 35 years. Now it is hard to find a pimple on my body.9. I have always had to fight dehydration. That is no longer a problem.10. I used to drink two large cups of coffee every morning just to be able to function. I now have enough energy that I have eliminated caffeine from my diet.11. I sleep more soundly than ever before and my dreams are clear and vivid.12. My thought processes are more active and clear than they have ever been. 13. My chronic sinus issue is now a thing of the past.14. I used to have problems with getting the “shakes” if I had gone more than a couple of hours without eating. It was as if I was suffering from low blood sugar. I would even be afraid that I would pass out. Now all I feel is hunger. I can go all day without eating and never feel in danger of losing consciousness. Today is Thursday. This past Monday my wife and I were eating out and I ordered a burger without a bun. What I didn’t realize was that the burger would arrive covered in onion rings. I knocked the mountain of onion rings onto the plate but there were still a couple that were embedded in the cheese. I decided, what the hell, a couple of onion rings shouldn’t make that much of a difference. I will not make that mistake again anytime soon. Within 30 minutes I felt like there was a steel spike going through my left eye socket. I don’t remember ever being in that much pain. My sinuses were exploding. This morning, as I write this, I still feel the vestiges of that pain. Just enough that I know it is there. But after two and a half days, I am at least able to function again. I owe you a debt of gratitude. You may have just saved my life. In the very least you have given me the means to improve my life in ways that I never thought possible. Thank you so much,Michael B.Now, if wheat exposure can do that in Michael, what damage can it do in other people? Personally, I previously experienced many of the same symptoms that Michael suffered, all gone with wheat elimination. My advice: If you have any inkling that you might have a wheat sensitivity, make a New Year's resolution to stay wheat-free for 4 weeks and see whether you can feel any difference. Not everybody will, but many will be telling us about the dramatic health turnarounds they experienced.
Lipoprotein lipase and you 30. December 2009 William Davis (0) Lipoprotein lipase can make the difference between having heart disease and not having it. Having sky-high triglycerides or normal triglycerides. It can mean dinner hanging around for over 12 hours in the bloodstream, rather than the usual 4-6 hours.
If you take niacin, you must exercise 30. December 2009 William Davis (23) We use a lot of niacin in the Track Your Plaque program. Niacin:--Increases HDL and shifts HDL towards the large, protective fraction--Reduces small LDL--In fact, niacin is the best treatment we have to reduce small LDL after wheat elimination and carbohydrate reduction.--Reduces fasting and postprandial (after-eating) triglycerides--Reduces heart attack risk by 20-28%--even as a sole agent. But . . . niacin also triggers higher blood sugar because it partially blocks the effects of insulin (insulin "resistance").While the net effect of niacin remains positive, the provocation of insulin resistance is not such a good thing. Can it be minimized or eliminated? Yes, through exercise. Here's one interesting observation in obese (BMI 34.0), sedentary men given placebo, exercise, niacin (1500 mg Niaspan, once per day), or niacin + exercise: From Plaisance et al 2008. Blood was drawn following a high-fat meal challenge. (Yes, a high-fat challenge, not a carbohydrate challenge. In this study, there were only 17 grams carbohydrates in the test meal, but 100 grams fat. More on this in future.) Exercise consisted of walking for 50 minutes at a moderate pace one hour prior to the meal challenge.You can see from the graph that exercise partially corrected the increased insulin level provoked by niacin. Judging from this and other studies, exercise can help minimize the insulin-blocking effects of niacin. It doesn't take much, just moderate exercise for at least 30 minutes. Adequate sleep can also help, since sleep deprivation is a potent trigger for insulin resistance, only worsened in the presence of niacin. Vitamin D supplementation to achieve desirable blood levels (which I define as 60-70 ng/ml) is also an effective means to minimize this effect.
To track small LDL, track blood sugar 24. December 2009 William Davis (28) Here's a trick I learned after years of fussing over people's small LDL. To gain better control over small LDL, follow blood sugars (blood glucose). When you think about it, all the foods that trigger increases in blood sugar also trigger small LDL. Carbohydrates, in general, are the most potent triggers of small LDL. The most offensive among the carbohydrates: foods made with wheat. After wheat, there's foods made with cornstarch, sucrose (table sugar), and the broad categories of "other" carbohydrates, such as oats, barley, quinoa, sorghum, bulghur, etc. Assessing small LDL requires a full lipoprotein assessment in which small LDL particles are measured (NMR, VAP, GGE). Not the easiest thing to do in the comfort of your kitchen. However, you can easily and now cheaply check your blood sugar. Because blood sugar parallels small LDL, checking blood sugar can provide insight into how you respond to various foods and know whether glucose/small LDL have been triggered. Here's how I suggest patients to do it:1) Purchase an inexpensive blood glucose monitor at a discounter like Walmart or Walgreen's. You can buy them now for about $10. They're even sometimes free with promotional offers. You will also need to purchase lancets and test strips. 2) With a meal in question, check a blood sugar just prior to the meal, then again 60 minutes after finishing the meal. Say, for example, your pre-meal blood sugar is 102 mg/dl. You eat your meal, check it 60 minutes after finishing. Ideally, the postprandial (after-meal) blood sugar is no more than 102 mg/dl, i.e., no higher than pre-meal. Perhaps you're skeptical that oatmeal in skim milk with walnuts and raisins will do any damage. So you perform this routine with your breakfast. Blood sugar beforehand: 100 mg/dl. Blood sugar 1 hour post: 163 mg/dl--Uh oh, not good for you. And small LDL will be triggered. This approach is not perfect. It will not, for example, identify "stealth" triggers of blood sugar and small LDL like pasta, for the same reasons that pasta has a misleadingly low glycemic index: sugars are released slowly and not fully evident with the one-hour blood sugar. Nonetheless, for most foods and meals, tracking your one-hour postprandial blood sugar can provide important insight into your individual susceptibility to sugar and small LDL-triggering effects.
C-reactive protein: Fiction from the drug industry? 21. December 2009 William Davis (0) C-reactive protein (CRP) is the liver product of inflammatory responses anywhere in the body. If there's an inflamed left knee, CRP will be increased. If viral bronchitis is making you cough, then CRP will be increased. The argument put forward by the drug industry is that, because CRP indicates underlying inflammation, very low-grade levels that can be measured in the absence of overt inflammation like the sore knee or bronchitis is associated with increased risk for cardiovascular events. There are now many studies that conclusively demonstrate that, the higher the CRP, the greater the cardiovascular risk. Naturally, any marker of risk is followed by the inevitable study: Do statin drugs reduce the excess cardiovascular risk of excessive CRP? And, yes, indeed they do. My statin-crazed colleagues rave about the so-called "pleiotropic," or non-lipid, effects of statins. CRP reduction and the reduction of risk associated with CRP result with statin treatment. But is life really statin vs. placebo, as most statin trials are constructed? Are there strategies that can outdo statins like Crestor for reduction of CRP?
Watch your fish oil labels 17. December 2009 William Davis (36) A quick quiz: How much omega-3 fatty acids, EPA + DHA, are in each capsule of fish oil with the composition shown on the label below:If you said 1340 mg (894 mg + 446 mg), sorry, but you're wrong. There are 670 mg EPA + DHA per capsule. Did you notice that the composition, or "Supplement Facts," lists the contents of two capsules? Rather than the usual one capsule contents, this product label lists two capsules. I don't know why some manufacturers or distributors do this. However, I have seen many people tripped up by this kind of labeling, taking half the omega-3 fatty acids they thought they were taking. This can be important when you are trying to obtain a specific dose of EPA + DHA to reduce triglycerides, reduce Lp(a), control abnormal heart rhythms, reduce bipolar mood swings, or other important effects. I liken this to pulling up to a gas station where the sign says gasoline for $1.25. Wow! Can't beat that! You then find out that it's really $1.25 for a half-gallon, or $2.50 a gallon. In truth, the labeling is accurate; it's just very easy to not notice the two capsule composition.
Why do I need a prescription for Olava? 16. December 2009 William Davis (0) Imagine this:What is OLAVA?Olava is prescription olive oil. It is the purest, highest concentration of olive oil available. Why Do I Need a Prescription for OLAVA?Studies show that olive oil contains essential fatty acids, "good" fats that:--Contain natural compounds your body needs for good health but can't produce on its own.--Has antioxidants that may provide protection from heart disease.So, it is common for people to ask why they need a prescription for OLAVA if it is made from a natural ingredient--olive oil. It's time to get the facts about OLAVA. Learn why OLAVA is different from olive oil you can buy at a store.
