Bait and switch 23. March 2008 William Davis (5) “When banks compete, you win.”The TV ad opens with a 60-something man sitting in his living room, talking to a three-piece suit-clad, 30-something banker. The older man is explaining to the dismayed younger man why he’s going to use Lending Tree loan service for a home loan.“But Dad, I’m you’re son!” the younger whines. Many of Lending Tree’s clients have collaborated in filing a multi-million dollar class action suit against the company, claiming “bait and switch” tactics. They claim that home buyers are lured by low interest rates or low closing costs on a home loan. Once the buyer concludes the hassle of filling out numerous forms, the suit accuses Lending Tree of making a switch to a costlier loan.Bait and switch is among the oldest con games around. If you’ve ever bought a car from a car dealer, chances are you’ve had your own little brush with this deception. The ad promises the SUV you’ve wanted for only $299 per month. Only, once you get there, the salesman informs you that only a limited number of special deals were available and they’ve run out. But he’s still got a really good deal right over here! Most of us recognize that we’ve been hookwinked. Yet we still go along and buy a car from the dealer. What if it’s not a sleazy salesman behind the pitch, but a physician. If it’s hard to resist the sales pitch at the car dealership, it can be near impossible to ignore the advice of your doctor. But the truth is often loud and clear: in many instances, it is a genuine, bona fide, and fully-certified scam. Among the most common bait-and-switch heart scams: Your cholesterol is high. The sequence of subsequent testing is well-rehearsed. “Gee, Bob, I’m worried about your risk for heart disease. Let’s schedule you for a nuclear stress test.” The stress test, like 20% or more of them, is “falsely positive,” meaning abnormal even though there’s nothing wrong with you. Another 30% are equivocal, not clearly abnormal but also not clearly normal. Now up to 50% of people tested “need” a heart catheterization in the hospital to clarify this frightening uncertainty. You might end up with a stent or two, even bypass surgery. Your simple $20 cholesterol panel has metamorphosed into $100,000 in hospital procedures. That familiar sequence is followed thousands of times, seven days a week, 365 days a year.There are times when these heart tests are valuable and provide meaningful answers. Then there's the other half of the time when they provide murky information that can be used for a practitioner's economic advantage.Copyright 2008 William Davis, MD Toggle navigation Home Blog Home Archive Join Now Log in NY Times Jane Brody misses the mark 9. October 2007 William Davis (6) NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper: "CT Scans of the Heart Come With Trade-Offs In her report, she says:Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent. This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like: --the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk ton glyphicon-comment">(18) Gwen was miserable and defeated. No wonder. After a bypass operation failed just 12 months earlier with closure of 3 out of 4 bypass grafts, she has since undergone 9 heart catheterization procedures and received umpteen stents. She presented to me for an opinion on why she had such aggressive coronary disease (despite Lipitor). No surprise, several new causes of heart disease were identified, including a very severe small LDL pattern: 100% of LDL particles were small. Given her stormy procedural history, I urged Gwen to immediately drop all processed carbohydrates from her diet, including any food made from wheat or corn starch. (She and her husband were shocked by this, by the way, since she'd been urged repeatedly to increase her whole grains by the hospital dietitians.) I also urged her to begin to lose the 30 lbs of weight that she'd gained following the hospital dietitians' advice. She also added fish oil at a higher-than-usual dose. I asked her to add niacin, among our most effective agents for reduction of small LDL particles, not to mention reduction of the likelihood of future cardiovascular events. Although I instructed Gwen on where and how to obtain niacin, she went to a health food store and bought "no-flush niacin," or inositol hexaniacinate. She was curious why she experienced none of the hot flush I told her about. When she came back to the office some weeks later to review her treatment program, she told me that chest pains had returned. On questioning her about what she had changed specifically, the problem became clear: She'd been taking no-flush niacin, rather than the Slo-Niacin I had recommended. What is no-flush niacin? It is inositol hexaniacinate, a molecule that indeed carries six niacin molecules attached to an inositol backbone. Unfortunately, it exerts virtually no effect in humans. It is a scam. Though I love nutritional supplements in general, it pains me to know that supplement distributors and health food stores persist in selling this outright scam product that not only fails to exert any of the benefits of real niacin, it also puts people like Gwen in real danger because of its failure to provide the effects she needed. So, if niacin saves lives, no-flush niacin in effect could kill you. Avoid this scam like the plague. No-flush niacin does not work. Period. Disclosure: I have no financial or other relationship with Upsher Smith, the manufacturer of Slo-Niacin. Copyright 2008 William Davis, MD Breakfast comments 19. March 2008 William Davis (7) I received some wonderful comments to the What's for breakfast blog post. Even though comments are viewable by clicking on them, I wanted to be sure these were readily visible, since they were so helpful and augmented the few suggestions I made. I'm impressed with the variety of foods people are willing to introduce into breakfast, particularly foods not traditionally thought to be part of standard American breakfast choices. I normally eat a handful of almonds, some raw cashews, and occasionally an orange for breakfast. I used to eat cheese with breakfast also, but found once I began eating cheese it was hard for me to stop at one or two pieces. AnonymousMy favorite breakfast is often left over Thai curry. I omit the rice. I also like making a thai omelet which is simply 2 eggs and some fish sauce and water and serving it with Sirachi sauce or Thai peanut sauce. It is street vendor food in Thailand I hear. Here's a recipe. I find left over dinners are quite wonderful for breakfast. You just have to get past this notion that you have to eat certain foods at certain times in the day. Where'd that idea come from anyway?ZuteI’ve tried eating oatmeal throughout my life, really wanting to like it. Until now the mere taste or smell of it made my stomach queasy. The key for me was toasting the oatmeal. Here’s what I generally do:For Steel-cut oatmeal with the taste and texture of rice pudding-In a frypan:Toss 1 TBS of butter or so into a hot pan.Add 1 cup of steel-cut oatmeal until toasted.--few minutesIn a saucepan:Boil 2-1/2 cups waterAdd 1 cinnamon stick (or equivalent)Add toasted Steel-cut oatmeal and cook for 15-20 minutes or soAdd 1-1/2 cups of low-fat milk, yogurt, or some combination, etc…-Optional- Wisk an egg yolk into the milk.-Optional- Add ¼ tsp salt.-Optional- 2 TBS honey or Brown sugar. I use one 1 TBS of each.Add some lemon or orange zestReturn to a boil for 10-15 minutes and then chill before eating. The oatmeal will congeal, resembling rice pudding.Sprinkle more cinnamon/sugar on topAdd what you like: raisins, nuts, etc...Use the cinnamon stick if you can, it really makes the difference. I’m constantly refining this recipe.AnonymousOnce I decided to give up my (former) love affair with breakfast cereals, I was in a quandary about what to do for breakfast. I don't have much time in the morning to get creative and don't have the inclination at that time of the day to do so either.I've settled on a routine of 2 hard-boiled (organic free-range) eggs (I boil them up a week in advance and leave them, shells-on, in the fridge), and a home-made protein-berry smoothie (frozen organic unsweetened berries, water-based).This 8 am combo is easy, fast and tasty (I vary the berries and sometimes add natural flavour extracts for variety). It keeps my blood sugar flat and me full until my 1pm lunchtime. And I don't miss the cereals one bit!AnonymousI met an out-of-town friend for breakfast the other morning at a French-style bakery cafe. I ordered the goat cheese and herb omelet, but said I didn't want the potatoes or bread with it. They offered extra fruit or a salad instead. I chose the salad, with olive oil and vinegar. My friend wondered how I could eat a salad so early. Why not?At home I usually eat 2 or 3 eggs over easy cooked in butter for breakfast most mornings and I am comfortably hungry for lunch about 3-4 hours later. But after my nicely filling cheese omelet and generous romaine salad (with a tiny bit of fruit - I ate the berries/melon and left the super-sweet pineapple), I wasn't hungry again until very late in the afternoon so had a small snack (cheese and half an apple) to hold me off and ate my next meal at dinner time. And it was a slow-developing comfortable hunger, not the powerful, "gotta eat something, anything" hunger that follows carb-heavy food.Breakfast food, indeed!AnnaYou are absolutely right - breakfast is the most difficult meal to change. When I gave up wheat, I started using brown rice or potatoes mixed with anything interesting - nuts or meat or veges. I have now learned that these carbs make my blood glucose skyrocket. I have dropped the rice and potatoes and my BG has dropped nicely.My favorite breakfast is sauteed veggies with some leftover meat or even an omelette. Soups are great in the AM. Nuts are for the days I am in a hurry.Would be a little easier if I were not dairy intolerant.AnneHere in South India,it is 'Idli' - steam-cooked Lentil-rice (predominantly lentil) droppings, and 'Dosa' - lentil-rice pancakes. We have altered it a bit by increasing lentil ratio and dropping the rice to a minimum. Tastes good and fills you nice, for 4-5 hours.NeeleshI have two or three eggs, usually scrambled, but sunny-side-up and over-easy get thrown in for variety. I cook them using butter made from grass-fed cows. I also make my scrambled eggs using whipping cream instead of the more typical water or milk. I'll put a spoonful of fresh-made salsa over the top for some zing, some sliced cheese on the side and a cup of whole, organic milk to drink.I'm completely sold on the "high-fat, moderate-protein, low-carb" diet and especially the admonition to start the day with a strong breakfast. My overall energy levels are fantastic, running performance is as good as high-school, and my belly hasn't looked this tight in decades.Ross What's for breakfast? 16. March 2008 William Davis (106) Breakfast, for some reason, seems to be the toughest meal of the day for many people. I think it's because the quest for sweet has dominated the American breakfast for so long, with its half-century legacy of cartoon character-festooned breakfast cereals; baked flour products like pancakes, waffles, and English muffins; more recently, "healthy" alternatives like bran muffins and oat waffles. This breakfast lifestyle has also contributed to the obesity and diabetes ("diabesity") epidemic. Breakfasts of wheat- or corn-based cereals, even those labeled "heart healthy," fruit, and whole grain breads are guaranteed paths to low HDL cholesterol, high triglycerides, flagrant small LDL, increased inflammatory responses, high blood pressure, and higher blood sugar. Such foods also make you tired, make your abdominal fat grow (wheat belly), and increase appetite so that you want more. So what can you eat for breakfast that doesn't provoke these patterns? I will never pretend to be terribly clever in creating meal menus, but I can tell you what has worked for me and many of my patients. Be warned: It may require you to suspend your previous notions of what "should" be included in a list of breakfast foods.Here are some examples that you may find helpful:--Raw nuts--one or several handfuls of raw almonds, walnuts, pecans, pistachios--Cheeses--the real, traditional sorts like gouda, goat, Swiss, edam, etc. (not Velveeta, Cheez Whiz, etc.)--Eggs, Egg Beaters--and "spice" them up with sun-dried tomatoes, salsa, olives, tapenades, olive oil, onions, green peppers, etc.--Yogurt (real, of course), cottage cheese--Ground flaxseed, oat bran--as hot cereals or added to yogurt, cottage, or other foods. Esp. helpful for reducing both total LDL and the proportion of small LDL.--Oatmeal--slow-cooked, not the instant nonsense.--Soups--great for winter.--Dinner foods--chicken, beef, fish, green beans, asparagus, tomatoes, etc., most easily added by saving left-overs from dinner. You'll be surprised how filling dinner foods eaten at breakfast can be. It's really not that tough. It just means selecting from an entirely different list of foods than you might be accustomed to. Copyright 2008 William Davis, MD The first lawsuit? 16. March 2008 William Davis (1) The closing arguments in actor John Ritter's wrongful death lawsuit are over and the two doctors charged with negligence cleared, five years after his death from a dissection (tear of the inner lining) of the thoracic aorta. The family sought $67 million in damages, claiming that the aortic dissection was misdiagnosed as a heart attack and that the enlarged aorta should have been reported to Mr. Ritter two years earlier during a full body scan. The AP story can be viewed at http://ap.google.com/article/ALeqM5gmv6HnJJPBee2gWgEYResT5m6YkAD8VDF9CO0 Well, perhaps this is the start of a trend. Up until now, it has been commonplace for doctors to ignore many of the important findings on heart scans, full body scans, and similar direct-to-the-public imaging services. For instance, similar to John Ritter's case, enlarged thoracic aortas are commonly ignored. I'd even say that as a rule they are ignored. I have seen many patients in consultation who have had large aortas identified on heart scans, yet nothing--not a thing--was done about it. While the doctors escaped a lawsuit this time, it might not happen a second time. I truly hope that Mr. Ritter's unfortunate experience and the consequent lawsuit do not trigger the usual defensive medicine response of resorting to major procedural "solide that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.TYP: 180 lbs of weight loss in your first year is absolutely astounding. I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently? How are your food choices today different from that first year? JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).There's a balance that people need to find for themselves and it's different for all of us. I am one of the unlucky people who has to keep his carbohydrate intake below 50g daily or I gain. It's just a fact of life that I've come to grips with and realize is a necessity in order to manage my weight for the rest of my life. But I wouldn't have it any other way!Exercise was indeed a part of my low-carb weight loss success in 2004 as I forced myself to do cardio every single day as a commitment to this journey. In hindsight, that was probably not the best thing for me to do since the body has a rather peculiar way of telling you it needs to wiggle and move spontaneously on its own rather than forcing the issue. But I consider the exercise I did to be such an integral part of my success that I dedicated an entire chapter of my book to the subject.Today, my daily cardio routine is out the window and I choose instead to engage in activities outside the gym that let me burn calories and have some fun in the process. I regularly play volleyball, basketball, and referee flag football at my church which all give me quite a workout. I'm very physically active and fit on my 6'3" body and just enjoy burning off all this excess energy that I have been given since losing nearly have my weight! I do want to get into a little more organized resistance training routine soon to try to shape and tone some areas of my body that still show signs of that 410-pound man I used to be (although the loose, hanging skin in my abdomen and inner thighs isn't going to get any better with exercise since the elasticity has been ruined from being stretched out so far). Here is a link to some posts and pictures I have written about this subject:http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.htmlAs for my food choices today compared to my weight loss year in 2004, they haven't really changed a whole lot. This was a lifestyle change in every sense of the phrase and I've learned to implement this way of eating into a permanent and healthy diet that I can and will gladly live with forever and ever amen. I probably eat more berries, melons, and nuts today than I did then, but otherwise it's the identical diet. TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years. Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins? JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone. Nope, I sure don't!Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.Anyone interested in doing the low-carb lifestyle and needs help finding which plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html). It's the perfect overview of low-carb living with a comparison and recap of the major plans.THANK YOU again for allowing me to share my story with you and your readers, Dr. Davis!

October 2007 William Davis (3) Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)Both are also meant to be repeated periodically when normal as a surveillance process.Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography. CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries. One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency. Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go. Dr. Susie Rockway on conjugated linoleic acid (CLA) 5. October 2007 William Davis (7) I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements. A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives. So I asked Dr. Rockway if she’d answer a few questions for us. TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic? Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!) I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction! Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health. I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently. So, how can you not be excited about this very bioactive molecule? TYP: What are your specific areas of interest in nutrition and health? Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health. As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should. Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there. Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at. Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research. TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts? Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood. So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure. TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years? Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short! We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education. Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition. See, it all comes back to CLA!TYP: Thanks, Susie!

Which is better? 4. October 2007 William Davis (12) If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:Lipitor or a combination of fish oil, vitamin D, and elimination of wheat? Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%. A combination of fish oil, vitamin D, and elimination of wheat: Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events. On this combination, however, you also:--Lose weight, often substantially. --Improve bone health, esp. osteoporosis and arthritis. --Reduce cancer risk from the vit D supplementation. --Reduce risk of stroke. --Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.--Reduce winter blues. --Experience more energy. --Obtain increased clarity of thought (from elimination of wheat). --Reduce blood pressure. Oh, and there's no muscle aches. Heart health for stupid people 4. October 2007 William Davis (3) I'm kidding.What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public. A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:Eat healthy--by eating a "balanced" diet low in saturated fatDon't smokeExerciseDon't ignore chest pain symptoms or breathlessnessKnow your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?How about some real heart healthy advice:Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice. Copyright 2007 William Davis, MD Money, money, money, money 3. October 2007 William Davis (3) I've been asked the question numerous times:Why aren't heart scans more popular? First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is: Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice? That's easy: There's no money in it.Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans. This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer. Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan. With heart scans, there simply is no big payoff. We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area. The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money. I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007. The many faces of LDL 3. October 2007 William Davis (13) Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:LDL cholesterol: 96 mg/dlThis value puts Ginnie's LDL in the most favorable 25% in the country.LDL particle number: 2140 nmol/lThis value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).In addition, over 90% of Ginnie's LDL particles fell into the small class.Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:Apoprotein B somewhere in the 120 to 140 mg/dl rangeDirect LDL 100-130 mg/dl range.In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.We will be working on some solutions in the coming months.Copyright 2007 William Davis, MD What does "Success" mean in the Track Your Plaque program? 2. October 2007 William Davis (11) Say you begin with a CT heart scan score of 400. You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns. One year later, you get another heart scan. What score would constitute "success"?With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed? For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack.

NY Times Jane Brody misses the mark 9. October 2007 William Davis (6) NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper: "CT Scans of the Heart Come With Trade-Offs In her report, she says:Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent. This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like: --the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk ton glyphicon-comment">(18)
Breakfast comments 19. March 2008 William Davis (7) I received some wonderful comments to the What's for breakfast blog post. Even though comments are viewable by clicking on them, I wanted to be sure these were readily visible, since they were so helpful and augmented the few suggestions I made. I'm impressed with the variety of foods people are willing to introduce into breakfast, particularly foods not traditionally thought to be part of standard American breakfast choices. I normally eat a handful of almonds, some raw cashews, and occasionally an orange for breakfast. I used to eat cheese with breakfast also, but found once I began eating cheese it was hard for me to stop at one or two pieces. AnonymousMy favorite breakfast is often left over Thai curry. I omit the rice. I also like making a thai omelet which is simply 2 eggs and some fish sauce and water and serving it with Sirachi sauce or Thai peanut sauce. It is street vendor food in Thailand I hear. Here's a recipe. I find left over dinners are quite wonderful for breakfast. You just have to get past this notion that you have to eat certain foods at certain times in the day. Where'd that idea come from anyway?ZuteI’ve tried eating oatmeal throughout my life, really wanting to like it. Until now the mere taste or smell of it made my stomach queasy. The key for me was toasting the oatmeal. Here’s what I generally do:For Steel-cut oatmeal with the taste and texture of rice pudding-In a frypan:Toss 1 TBS of butter or so into a hot pan.Add 1 cup of steel-cut oatmeal until toasted.--few minutesIn a saucepan:Boil 2-1/2 cups waterAdd 1 cinnamon stick (or equivalent)Add toasted Steel-cut oatmeal and cook for 15-20 minutes or soAdd 1-1/2 cups of low-fat milk, yogurt, or some combination, etc…-Optional- Wisk an egg yolk into the milk.-Optional- Add ¼ tsp salt.-Optional- 2 TBS honey or Brown sugar. I use one 1 TBS of each.Add some lemon or orange zestReturn to a boil for 10-15 minutes and then chill before eating. The oatmeal will congeal, resembling rice pudding.Sprinkle more cinnamon/sugar on topAdd what you like: raisins, nuts, etc...Use the cinnamon stick if you can, it really makes the difference. I’m constantly refining this recipe.AnonymousOnce I decided to give up my (former) love affair with breakfast cereals, I was in a quandary about what to do for breakfast. I don't have much time in the morning to get creative and don't have the inclination at that time of the day to do so either.I've settled on a routine of 2 hard-boiled (organic free-range) eggs (I boil them up a week in advance and leave them, shells-on, in the fridge), and a home-made protein-berry smoothie (frozen organic unsweetened berries, water-based).This 8 am combo is easy, fast and tasty (I vary the berries and sometimes add natural flavour extracts for variety). It keeps my blood sugar flat and me full until my 1pm lunchtime. And I don't miss the cereals one bit!AnonymousI met an out-of-town friend for breakfast the other morning at a French-style bakery cafe. I ordered the goat cheese and herb omelet, but said I didn't want the potatoes or bread with it. They offered extra fruit or a salad instead. I chose the salad, with olive oil and vinegar. My friend wondered how I could eat a salad so early. Why not?At home I usually eat 2 or 3 eggs over easy cooked in butter for breakfast most mornings and I am comfortably hungry for lunch about 3-4 hours later. But after my nicely filling cheese omelet and generous romaine salad (with a tiny bit of fruit - I ate the berries/melon and left the super-sweet pineapple), I wasn't hungry again until very late in the afternoon so had a small snack (cheese and half an apple) to hold me off and ate my next meal at dinner time. And it was a slow-developing comfortable hunger, not the powerful, "gotta eat something, anything" hunger that follows carb-heavy food.Breakfast food, indeed!AnnaYou are absolutely right - breakfast is the most difficult meal to change. When I gave up wheat, I started using brown rice or potatoes mixed with anything interesting - nuts or meat or veges. I have now learned that these carbs make my blood glucose skyrocket. I have dropped the rice and potatoes and my BG has dropped nicely.My favorite breakfast is sauteed veggies with some leftover meat or even an omelette. Soups are great in the AM. Nuts are for the days I am in a hurry.Would be a little easier if I were not dairy intolerant.AnneHere in South India,it is 'Idli' - steam-cooked Lentil-rice (predominantly lentil) droppings, and 'Dosa' - lentil-rice pancakes. We have altered it a bit by increasing lentil ratio and dropping the rice to a minimum. Tastes good and fills you nice, for 4-5 hours.NeeleshI have two or three eggs, usually scrambled, but sunny-side-up and over-easy get thrown in for variety. I cook them using butter made from grass-fed cows. I also make my scrambled eggs using whipping cream instead of the more typical water or milk. I'll put a spoonful of fresh-made salsa over the top for some zing, some sliced cheese on the side and a cup of whole, organic milk to drink.I'm completely sold on the "high-fat, moderate-protein, low-carb" diet and especially the admonition to start the day with a strong breakfast. My overall energy levels are fantastic, running performance is as good as high-school, and my belly hasn't looked this tight in decades.Ross
What's for breakfast? 16. March 2008 William Davis (106) Breakfast, for some reason, seems to be the toughest meal of the day for many people. I think it's because the quest for sweet has dominated the American breakfast for so long, with its half-century legacy of cartoon character-festooned breakfast cereals; baked flour products like pancakes, waffles, and English muffins; more recently, "healthy" alternatives like bran muffins and oat waffles. This breakfast lifestyle has also contributed to the obesity and diabetes ("diabesity") epidemic. Breakfasts of wheat- or corn-based cereals, even those labeled "heart healthy," fruit, and whole grain breads are guaranteed paths to low HDL cholesterol, high triglycerides, flagrant small LDL, increased inflammatory responses, high blood pressure, and higher blood sugar. Such foods also make you tired, make your abdominal fat grow (wheat belly), and increase appetite so that you want more. So what can you eat for breakfast that doesn't provoke these patterns? I will never pretend to be terribly clever in creating meal menus, but I can tell you what has worked for me and many of my patients. Be warned: It may require you to suspend your previous notions of what "should" be included in a list of breakfast foods.Here are some examples that you may find helpful:--Raw nuts--one or several handfuls of raw almonds, walnuts, pecans, pistachios--Cheeses--the real, traditional sorts like gouda, goat, Swiss, edam, etc. (not Velveeta, Cheez Whiz, etc.)--Eggs, Egg Beaters--and "spice" them up with sun-dried tomatoes, salsa, olives, tapenades, olive oil, onions, green peppers, etc.--Yogurt (real, of course), cottage cheese--Ground flaxseed, oat bran--as hot cereals or added to yogurt, cottage, or other foods. Esp. helpful for reducing both total LDL and the proportion of small LDL.--Oatmeal--slow-cooked, not the instant nonsense.--Soups--great for winter.--Dinner foods--chicken, beef, fish, green beans, asparagus, tomatoes, etc., most easily added by saving left-overs from dinner. You'll be surprised how filling dinner foods eaten at breakfast can be. It's really not that tough. It just means selecting from an entirely different list of foods than you might be accustomed to.

The first lawsuit? 16. March 2008 William Davis (1) The closing arguments in actor John Ritter's wrongful death lawsuit are over and the two doctors charged with negligence cleared, five years after his death from a dissection (tear of the inner lining) of the thoracic aorta. The family sought $67 million in damages, claiming that the aortic dissection was misdiagnosed as a heart attack and that the enlarged aorta should have been reported to Mr. Ritter two years earlier during a full body scan. The AP story can be viewed at http://ap.google.com/article/ALeqM5gmv6HnJJPBee2gWgEYResT5m6YkAD8VDF9CO0 Well, perhaps this is the start of a trend. Up until now, it has been commonplace for doctors to ignore many of the important findings on heart scans, full body scans, and similar direct-to-the-public imaging services. For instance, similar to John Ritter's case, enlarged thoracic aortas are commonly ignored. I'd even say that as a rule they are ignored. I have seen many patients in consultation who have had large aortas identified on heart scans, yet nothing--not a thing--was done about it. While the doctors escaped a lawsuit this time, it might not happen a second time. I truly hope that Mr. Ritter's unfortunate experience and the consequent lawsuit do not trigger the usual defensive medicine response of resorting to major procedural "solide that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.TYP: 180 lbs of weight loss in your first year is absolutely astounding. I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently? How are your food choices today different from that first year? JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).There's a balance that people need to find for themselves and it's different for all of us. I am one of the unlucky people who has to keep his carbohydrate intake below 50g daily or I gain. It's just a fact of life that I've come to grips with and realize is a necessity in order to manage my weight for the rest of my life. But I wouldn't have it any other way!Exercise was indeed a part of my low-carb weight loss success in 2004 as I forced myself to do cardio every single day as a commitment to this journey. In hindsight, that was probably not the best thing for me to do since the body has a rather peculiar way of telling you it needs to wiggle and move spontaneously on its own rather than forcing the issue. But I consider the exercise I did to be such an integral part of my success that I dedicated an entire chapter of my book to the subject.Today, my daily cardio routine is out the window and I choose instead to engage in activities outside the gym that let me burn calories and have some fun in the process. I regularly play volleyball, basketball, and referee flag football at my church which all give me quite a workout. I'm very physically active and fit on my 6'3" body and just enjoy burning off all this excess energy that I have been given since losing nearly have my weight! I do want to get into a little more organized resistance training routine soon to try to shape and tone some areas of my body that still show signs of that 410-pound man I used to be (although the loose, hanging skin in my abdomen and inner thighs isn't going to get any better with exercise since the elasticity has been ruined from being stretched out so far). Here is a link to some posts and pictures I have written about this subject:http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.htmlAs for my food choices today compared to my weight loss year in 2004, they haven't really changed a whole lot. This was a lifestyle change in every sense of the phrase and I've learned to implement this way of eating into a permanent and healthy diet that I can and will gladly live with forever and ever amen. I probably eat more berries, melons, and nuts today than I did then, but otherwise it's the identical diet. TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years. Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins? JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone. Nope, I sure don't!Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.Anyone interested in doing the low-carb lifestyle and needs help finding which plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html). It's the perfect overview of low-carb living with a comparison and recap of the major plans.THANK YOU again for allowing me to share my story with you and your readers, Dr. Davis!

Mammogram of the heart 6. October 2007 William Davis (3) Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)Both are also meant to be repeated periodically when normal as a surveillance process.Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography. CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries. One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency. Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.
Dr. Susie Rockway on conjugated linoleic acid (CLA) 5. October 2007 William Davis (7) I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements. A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives. So I asked Dr. Rockway if she’d answer a few questions for us. TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic? Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!) I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction! Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health. I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently. So, how can you not be excited about this very bioactive molecule? TYP: What are your specific areas of interest in nutrition and health? Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health. As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should. Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there. Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at. Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research. TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts? Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood. So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure. TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years? Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short! We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education. Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition. See, it all comes back to CLA!TYP: Thanks, Susie!

Which is better? 4. October 2007 William Davis (12) If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:Lipitor or a combination of fish oil, vitamin D, and elimination of wheat? Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%. A combination of fish oil, vitamin D, and elimination of wheat: Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events. On this combination, however, you also:--Lose weight, often substantially. --Improve bone health, esp. osteoporosis and arthritis. --Reduce cancer risk from the vit D supplementation. --Reduce risk of stroke. --Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.--Reduce winter blues. --Experience more energy. --Obtain increased clarity of thought (from elimination of wheat). --Reduce blood pressure. Oh, and there's no muscle aches.
Heart health for stupid people 4. October 2007 William Davis (3) I'm kidding.What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public. A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:Eat healthy--by eating a "balanced" diet low in saturated fatDon't smokeExerciseDon't ignore chest pain symptoms or breathlessnessKnow your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?How about some real heart healthy advice:Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice. Copyright 2007 William Davis, MD
Money, money, money, money 3. October 2007 William Davis (3) I've been asked the question numerous times:Why aren't heart scans more popular? First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is: Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice? That's easy: There's no money in it.Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans. This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer. Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan. With heart scans, there simply is no big payoff. We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area. The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, not your health interests. It's the same equation that drives food manufacturers to make more and more processed carbohydrate foods that they sell for substantial markups, not green peppers and cucumbers that make little money. I regard heart scans as among the greatest self-empowering tools in health ever conceived. It was that way in 1997; it remains that way in 2007.
The many faces of LDL 3. October 2007 William Davis (13) Ginnie came in for an opinion about her heart scan score of 393. At age 57, this put her in the 99th percentile, a high score.As usual, we did a lipoprotein analysis by NMR (Liposcience). Some numbers:LDL cholesterol: 96 mg/dlThis value puts Ginnie's LDL in the most favorable 25% in the country.LDL particle number: 2140 nmol/lThis value is in the worst 25% of the country and is the equivalent of an LDL cholesterol of 214 mg/dl (take off the zero).In addition, over 90% of Ginnie's LDL particles fell into the small class.Had we run some other values, how would they have turned out? These are my estimates (since we didn't actually run them in Ginnie), but having run side-by-side numbers in past, reasonable estimates would have put:Apoprotein B somewhere in the 120 to 140 mg/dl rangeDirect LDL 100-130 mg/dl range.In other words, conventional calculated LDL is the least reliable of all the ways of examining low-density lipoprotein.It can also go the other way: High calculated LDL, low LDL particle number or ApoB or direct LDL. And, indeed, these other measures have proven superior in their ability to predict "events" like heart attack over conventional calculated LDL.Unfortunately, relying on conventional LDL is like a broken speedometer on your car. You really can't gauge accurately how fast you're going; sometimes you could be way off. While insurance companies and many physicians still continue to balk at this argument, the data have already been generated that show that lipoprotein analysis (my bias is NMR) is not just superior, but enormously superior for accuracy and event prediction.In addition, lipoprotein analysis has proven a crucial tool that accounts for our extraordinary success in reducing and controlling CT heart scan scores in the Track Your Plaque program. I doubt that we could have achieved the same level of success using conventional lipids.I'm also aware of the logistical difficulties obtaining lipoprotein testing in a world enthusiastically supportive of hospital procedures and smugly ignorant of superior prevention tools like lipoprotein analysis. I've learned just how difficult it can be in our Track Your Plaque Member Forum; I've also learned about some strategies for obtaining these tests that I hadn't been aware of, thanks to the resourcefulness of our Members.We will be working on some solutions in the coming months.Copyright 2007 William Davis, MD
What does "Success" mean in the Track Your Plaque program? 2. October 2007 William Davis (11) Say you begin with a CT heart scan score of 400. You correct your lipoprotein pattterns, take fish oil, correct 25-OH-vitamin D3 to 50 ng/ml, correct your other hidden patterns, follow a diet suited to your patterns. One year later, you get another heart scan. What score would constitute "success"?With all of our recent talk about record-setting reductions in heart scan scores, is it really necessary to drop your score that much to succeed? For instance, is our latest record-setting 63% drop in score better than "only" a 10% drop in score? Both represent reversal of coronary plaque. Both signify huge reductions in risk for plaque rupture, or heart attack. You can read about how we view the various forms of success in the program by reading our latest Track Your Plaque Special Report, Winning Your Personal War with Heart Disease: The Track Your Plaque 5 Stages of Success.
