In search of wheat: We bake einkorn bread 12. June 2010 William Davis (6) With the assistance of dietitian and health educator, Margaret Pfeiffer,MS RD CD, author of Smart 4 Your Heart and very capable chef and breadmaker (previously, before she gave up wheat), we made a loaf of bread using Eli Rogosa's einkorn wheat. Recall that einkorn wheat is the primordial 14-chromosome wheat similar to the wild wheat harvested by Neolithic humans and eaten as porridge.The essential question: Has wheat always been bad for humans or have the thousands of hybridization experiments of the last 50 years changed the structure of gluten and other proteins in Triticum aestivum and turned the "staff of life" into poison? I turn to einkorn wheat, the "original" wheat unaltered by human manipulations, to figure this out. While einkorn wheat is still a source of carbohydrates, is it something we might indulge in once in a while without triggering the adverse phenomena associated with modern wheat? Here's what we did:This is the einkorn grain as we received it from Eli's farm. This was enough to make one loaf (approximately 3 cups). The einkorn grain is a dark golden color. I tried chewing them. They taste slightly nutty. They soften as they sit in your mouth.Here's Margaret putting the einkorn grain into the electric grinder.We tried to grind the grain by hand with mortar and pestle, but this proved far more laborious than I anticipated. After about 15 minutes of grinding, this is what I got:Barely 2 tablespoons. That's when Margaret fired up the electric grinder. (I can't imagine having to grind up enough flour by hand for an entire family. Perhaps that's why ancient cultures were thin despite eating wheat. They were just exhausted!)We added water, salt, and yeast, then put the mix into an electric breadmaker to knead the dough and keep it warm. We let the dough rise for 90 minutes, much longer than conventional dough. The einkorn dough "rose" very little. Margaret tells me that most dough made with conventional flour rises to double its size. The einkorn dough increased no more than 20-30%.The einkorn dough also distinctly smelled like peanut butter.After rising, we baked the dough at 350 degrees F for 30 minutes. This is the final product.Because I want to gauge health effects, not taste, the bread we made had no added sugar or anything else to modify taste or physiologic effect.On first tasting, the einkorn bread is mildly nutty and heavy. It had an unusual sour or astringent taste at the end, but overall tasted quite good. Next: What happens when we eat it? I'm going to give the einkorn bread (I've got to make some more) to people who experience acute reactions to conventional wheat and see if the einkorn does the same. I will also assess blood sugar effects since, after all, hybridizations or no, it is still a carbohydrate. Margaret Pfeiffer's book is available on Amazon:
Ezekiel said what? 10. June 2010 William Davis (24) Some people are reluctant to give up wheat because it is talked about in the Bible. But the wheat of the Bible is not the same as the wheat of today. (See In search of wheat and Emmer, einkorn and agribusiness.) Comparing einkorn to modern wheat, for example, means a difference of chromosome number (14 chromosomes in einkorn vs. 42 chromosomes in modern strains of Triticum aestivum), thousands of genes, and differing gluten content and structure. How about Ezekiel bread, the sprouted wheat bread that is purported to be based on a "recipe" articulated in the Bible? Despite the claims of lower glycemic index, we've had bad experiences with this product, with triggering of high blood sugars, small LDL, and triglycerides not much different from conventional bread. David Rostollan of Health for Life sent me this interesting perspective on Ezekiel bread from an article he wrote about wheat and the Bible. David argues that the entire concept of Ezekiel bread is based on a flawed interpretation. "I Want to Eat the Food in the Bible." Are you sure about that?Some people, still wanting to be faithful to the Bible, will discard the "no grain/wheat" message on the basis of biblical example. After all, God told Ezekiel to make bread, he gave the Israelites "bread from heaven," and then Jesus (who is called the "Bread of Life"!) multiplied bread, and even instituted the New Covenant with what? Bread and wine! If you're going to live the Bible, it seems that bread and/or wheat is going to play a part. But this is unnecessary. Sure, the Bible can and does tell us how to live, but this doesn't mean that everything in the Bible is meant to be copied verbatim. Applying the Bible to our lives requires wisdom, not a Xerox machine. The Bible was written in a historical context, and the setting happened to be an agricultural one. Because of this, the language used to describe blessing spoke of things like fields full of grain, or barns overflowing with wheat. Had the Bible been written in the context of a hunter-gatherer culture, the language describing blessing probably would have been about the abundance of wild game, or baskets full of vegetables. Whatever is most valuable in your time and in your culture is a blessing. God accommodated His message to the culture as it existed at the time. This is done throughout Scripture. There is a danger, then, in merely copying what the Bible says, instead of extracting the principles by which to live. Take the above example of Ezekiel, for instance. There's a whole product line in health food stores called "Ezekiel Bread" that supposedly copies the recipe given in Ezekiel 4:9. This is from the website: "Inspired by the Holy Scripture verse Ezekiel 4:9., 'Take also unto thee Wheat, and Barley, and beans, and lentils, and millet, and Spelt, and put them in one vessel, and make bread of it...'" Believing that this "recipe" has some kind of special power just because it's in the Bible is ridiculous. How ridiculous is it? I'll tell you in a moment, but first let me say that this is why it's so important not to confuse descriptives with prescriptives. Is the Bible telling a story, or is it telling us to do something? We would be well-advised not to confuse the two. In the case of the Ezekiel Bread, what is going on in the passage? There's a siege going on, with impending famine, and Ezekiel is consigned to eating what was considered back then to be some of the worst possible food. It was basically animal chow. But that's not the worst thing going on in this passage. Apparently, when the makers of Ezekiel Bread were gleaning their inspiration for the perfect recipe, they stopped shortof verse 12: "And thou shalt eat it as barley cakes, and thou shalt bake it with dung that cometh out of man, in their sight." Um...what? Well, there was a good reason for this. God was judging His people, and by polluting this really bad bread with dung (which was a violation of Mosaic law; Lev. 5:3), He was saying that they were no different from the unclean Gentiles. So why would we take this story and extrapolate a bread recipe from it? Beats me. If you were going to be consistent, though, here's what you'd have to end up with:Let that be a lesson to you. We don't just go and do everything that we see in the Bible.
Low-carb gynecologist 6. June 2010 William Davis (36) I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March. Dr. Fox is quiet and unassuming, but had incredible things to say about his experience with carbohydrate restriction in female infertility and pregnancy. While readers of The Heart Scan Blog already know that I advocate a diet free of wheat, cornstarch, and sugar for heart health and correction of multiple lipoprotein abnormalities, it was fascinating to hear how a similar approach seems to yield extraordinary benefits in this entirely unrelated area of female health. Obviously, female infertility and pregnancy are unrelated to heart health, but the extraordinary benefits witnessed by Dr. Fox in this area suggest that some fundamental lessons in human physiology can be learned. The results are so incredible that we are all sure to hear more about this approach as experience grows. So I tracked Dr. Fox down in his busy Jacksonville, Florida practice to fill us in on some details. WD: Dr. Fox, could you tell us something about yourself and what led you to use carbohydrate restriction in your female patients?MF: I have been in practice as a reproductive endocrinologist for 15 years. During that time, I have seen our specialty move from a broad based practice of reproductive endocrinology to a narrow IVF [in vitro fertilization] focus, with patients being pushed through IVF in a cookie-cutter fashion without any emphasis on non-medical therapy. Our focus has been to remain as a broad practice where we individualize care and attempt in every case to achieve pregnancy short of IVF. Five years ago, this continued quest for better care led us into the insulin resistance, low-carbohydrate metabolic world that has transformed our practice, although our practice offers all aspects of reproductive endocrinology including sub-specialized minimally invasive surgery, and all available infertility options.WD: I have been intrigued by your comments about improved fertility with the low-carb diet. Could you elaborate on this?MF: Yes, five years ago, as more information regarding Polycystic Ovarian Disease or Syndrome (PCOD/S) and its relationship to insulin resistance (high insulin levels) was emerging, we had a simple realization. As we've known for some time, insulin stimulates excess male hormone levels in the ovary, which disrupts ovulation and fertility. Then our job was to lower or virtually eliminate high insulin levels. Again, in simple fashion, we looked at physiology and realized that insulin is released only in response to dietary carbohydrates. Thus, elimination of carbohydrates should resolve the problem. This, in fact, is the effect that we have seen. In our previous approaches to PCOD, we utilized oral ovulation medicines generating pregnancy rates in the 40% range overall. Now, with the nutritional approach, for those patients that follow our recommendations, our pregnancy rates are over 90%! This has dramatically reduced the need for in vitro fertilization in these patients. To extend this idea further, we first started with relative low-carbohydrate diets, such as the South Beach diet, but quickly realized this didn't produce a metabolic effect. Over time, it has borne out that only the very low-carbohydrate diet (VLCD) approach produces significant metabolic change. Our impression then was that the current U.S. nutritional exposure probably increases insulin levels and that this has a detrimental effect on fertility. To counter this effect, we now recommend the VLCD to all fertility patients and their spouses. The pregnancy rates do seem much better overall, as well as seeing a reduction in miscarriage rates. For the first time at our national meeting last year, there were three articles that showed improved pregnancy rates in patients without PCOD or insulin resistance in IVF when Glucophage was used. This drug decreases insulin. This supports the idea that our entire population is subjected to fertility-reducing high-carbohydrate diet.WD: Do you see any other changes in these patients on the diet?MF: Yes. All metabolic parameters, as well as many common complaints, improve. Cholesterol and triglyceride levels improve, while "good" HDL cholesterol levels increase. Weight drops at a pace of 12 lbs per month very steadily and we have many many patients who have experienced 50lb wt loss. Blood pressure decreases steadily in these patients and we are often able to get them off of cholesterol and blood pressure medicines. Common symptoms such as anxiety, sleep disturbances, decreased energy, migraine headaches and depression all dramatically improve. Again we can often get patients off depression and migraine suppression medications. So this approach helps in a multitude of areas. This is your brain on wheat II 29. July 2010 William Davis (24) In the original Heart Scan Blog post, This is your brain on wheat, I discussed how opioid peptides (i.e., small proteins that act like opiates such as heroine or morphine) that result from digestion of wheat cause unique effects on the human brain, particularly addictive behaviors. I also briefly reviewed how elimination of wheat has been shown to reduce auditory hallucinations and other psychotic behaviors in a subset of people with paranoid schizophrenia. These two phenomena, addictions and schizophrenia, are most likely the result of exorphins that cross the blood-brain barrier. Exorphins--exogenous morphine-like compounds--can be blocked by opiate-blocking drugs like naloxone and naltrexone. Naloxone is used in hospitals to reverse morphine or heroine overdoses; naltrexone is being repackaged into a weight loss drug, since blocking wheat-derived exorphins reduces appetite. (Yes: The USDA tells us to eat more wheat, the drug industry sells us the antidote.) There's another way that wheat can affect the brain and nervous system: immune-activated damage. This is similar to the effect seen in celiac. There's even overlap with some of the antibody markers used to diagnose celiac, like the anti-gliadin antibodies and the anti-endomysium antibodies. The most common immune neurological syndrome consequent to wheat consumption is cerebellar ataxia, a condition in which an immune response causes damage to the Purkinje cells of the cerebellum, the portion of the brain responsible for balance and coordination. This results in stumbling, incoordination, incontinence, and eventually leads to reliance on a cane or walker and wearing a diaper. Average age of onset: 53 years. A shrunken, atrophied cerebellum can be seen on an MRI of the brain.Problem: Most people with central nervous system damage caused by wheat do not have any intestinal symptoms, like diarrhea and abdominal pain, the sort of symptoms usually associated with celiac disease. It means the first sign of wheat-induced brain damage may be bumping into walls and wetting your pants. There's no such thing as a "no-carb" diet 27. July 2010 William Davis (24) When I tell patients how I advise a wheat-free, cornstarch-free, sugar-free diet on the background of a low-carbohydrate diet, some people ask: "But can I live on a no-carb diet?"Well, there's no such thing as a "no-carb" diet. Low-carb, yes. No-carb, no.Here are the carbohydrate contents of various "low-carb" foods:Gouda cheese--3 oz contains 1.65 grams carbohydratesMozzarella cheese--1 cup contains 2.89 grams carbohydrates Walnuts--4 oz (56 nuts) contains 2.96 grams carbohydratesAlmonds--4 oz contains 1.38 grams carbohydratesSour cream--one-half cup contains 3.31 grams carbohydratesRed wine--3.5 oz glass contains 2.69 grams carbohydratesEggplant--1 cup cooked contains 8.33 grams carbohydratesGreen pepper--1 medium-sized raw contains 5.52 grams carbohydratesCucumber--1 medium contains 4.34 grams carbohydratesTomato--1 medium contains 4.82 grams carbohydrates (Nutrition data from USDA Nutrient Database)In other words, foods thought to be "low-carb" actually contain a modest quantity of carbohydrates. Such modest quantities of carbohydrates may not be enough to trip your blood sugar. But add up all the "low-carb" foods you consume over the course of a day and you can easily achieve 30 grams or more carbohydrates per day even without consuming any higher carbohydrate foods. Why doesn't your doctor try to CURE diabetes? 21. July 2010 William Davis (88) Imagine you have breast cancer. You go to your doctor and she says, "As your pain worsens, we'll help you with pain medication. We'll fit you with a special bra to accommodate the tumor as it grows. That's all we're going to do.""What?" you ask. "You mean just deal with the disease and its complications, but you're not going to help me get rid of it . . . cure it?" It would be incredibly shocking to receive such advice. Then why is that the sort of advice given when you are diagnosed with diabetes? Say you go to the doctor. Lab values show a fasting blood sugar of 156 mg/dl, HbA1c (a reflection of your previous 60 days average glucose) of 7.1%. Both values show clear-cut diabetes. Your doctor advises you to 1) start the drug metformin, then 2) talk to the diabetic teaching nurse or dietitian about an American Diabetes Association (ADA) diet. The ADA diet prescribed encourages you to increase carbohydrates and cut fats at each meal and maintain a consistent intake so that you don't experience hypoglycemic (low blood sugar) episodes. You follow the diet, which causes you to gain 10-15 lbs per year, increasing your "need" for diabetes medication. You doctor adds Actos, then Januvia, then injections of Byetta. Three years and 34 lbs later, you are not responding well to the drug combination with blood sugars rarely staying below 200 mg/dl. You've developed protein in your urine ("proteinuria"), lost 30% of your kidney function, and you are starting to lose sensation in your feet. So the doctor replaces some of your medication with several insulin injections per day. This formula is followed millions of times per year in the U.S. So where along the way did your doctor mention anything about a "cure"?Adult diabetes is the one chronic disease that nobody cares to cure. Treat it, maintain control over blood sugars, but cure it? Most physicians say it's impossible. The tragedy is that diabetes is a curable condition. I've seen it happen many times. Physicians dedicated to curing diabetes like low-carb expert, Dr. Mary Vernon, have cured it countless times. Dr. Eric Westman and colleagues have been building the case for the carbohydrate-restricted cure for diabetes with studies such as this. In this last study, of the 8 participants on insulin + medications at the start of the study, 5 no longer required medications at the close of the study--they were essentially non-diabetic. I tell patients that diabetes, in fact, is a disease you choose to have or not to have--provided you are provided the right diet and tools. Sadly, rarely are diabetics told about the right diet and tools. That's why Cadbury Schweppes has been a major contributor to the American Diabetes Association, as are other processed food manufacturers and the drug industry, all who stand to profit from maintaining the status quo. The cure? Eliminate or at least dramatically reduce carbohydrates, the foods that increase blood sugar. Note: If you have diabetes and you are taking any prescription agents, such as glyburide, glipizide, insulin, and some others, you will need to discuss how to manage your medications if you reduce carbohydrates. The problem is finding a doctor or other resource to help you do this. LDL pattern B 18. July 2010 William Davis (17) Here's a Q&A I stumbled on in the Forum of MedHelp, where people obtain answers from presumed health "experts." Question:My VAP test results in July 07 identified an LDL Pattern B. Overall results: Total 150 HDL 75 LDL 61 Trig 60 HDL-2 17 LP(a) 6.0 LDL Pattern B Medications: Lipitor 10mg Zetia 10mg Altace 10mg Atenolol 50mg Plavix 75mg Aspirin 81mg I had several heart attacks which resulted in CABG performed May 2000. I am a 53 year old white male , 6'1", 190 pounds, exercise every day, watch my diet and feel great. Everything looks OK except my LDL Pattern B. Is there any therapy to improve the Patten B? Answer from CCF, MD:Your results indicate an LDL pattern B, which generally indicates small atherogenic LDL particles which may cause increased risk for CAD. However, there are several problems with LDL patterning: 1) its unreliability (of LDL pattern testing ), 2) unclear clinical evidence regarding regarding the usefulness of LDL patterns and particle size. The majority of evidence regarding the progression of atherosclerosis is with LDL lowering and to an smaller extent HDL raising. All available clinical evidence shows that any particles in the VLDL, IDL, or LDL range are atherogenic, and there is no evidence that whether belonging to pattern A or B one is more atherogenic than others. Subclass studies have proliferated over the last few years, but many of these studies were funded or subsidized either by suppliers of the assays as a method to expand their use and move them into mainstream practice, or by pharmaceutical companies in an attempt to claim some advantage over other therapeutic agents. Thus, current data on LDL subclasses are at best incomplete and at worst misleading, suffering from publication bias, and now given the recent results of the Ensign et al. study, unreliable. Your LDL, and HDL are at goal. The Lpa level is still not clearly linked as a modifiable risk factor for CAD, although elevated levels are now know to be linked to stroke. Continue with your present treatments: aspirin, plavix, ateonol and altace are all essential medications. Wow. The extent of ignorance that pervades the ranks of my colleagues is frightening. Contrary to the response, LDL particle size assays are quite reliable and accurate. I've performed many thousands of lipoprotein assays and they yield reproducible and clinically believable results. For example, eliminate wheat, oats, cornstarch, and sugars and small LDL drops from 2400 nmol/L to 893 nmol/L (NMR)--huge drops. If repeated within a short period of time, the second measure will correspond quite closely. The data are also quite clear: Small LDL particles (i.e., "pattern B") are a potent predictor of cardiovascular events. What we lack are the treatment trials that show that reduction of small LDL results in reduced cardiovascular events. The reason for this is that small LDL research is not well-funded, since there is no prescription drug to treat small LDL, only nutritional means. Niacin (as Niaspan) is as close as it comes for a "drug" to reduce small LDL. But diet is far more effective. Given the questioner's fairly favorable BMI of 25.1 and his history of aggressive heart disease, it is virtually certain that he has what I call "genetic small LDL," i.e., small LDL that occur on a genetically-determined basis (likely due to variants of the cholesteryl-ester transfer protein, or CETP, or of hepatic lipase and others). Ignoring this man's small LDL will, without a doubt, consign him to a future of more heart attacks, stents, and bypass. Maybe by that time the data supporting the treatment of small LDL will become available. What increases blood sugar more than wheat? 15. July 2010 William Davis (38) Take a look at these glycemic indexes (GI):White bread 69Whole wheat bread 72Sucrose 59Mars bar 68White rice 72Brown rice 66I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:Kidney beans 29Chick peas 36Apple 39Ice cream 36Snickers Bar 40Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food. While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list. Take a look at this list:Cornflakes 80Rice cakes 80Rice Krispies 82Rice pasta, 92Instant potatoes 83Tapioca 81Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100. Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat. China fiction? 10. July 2010 William Davis (39) Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk. Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger. Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition. Her comments on the relationship of wheat to heart disease:Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease? Carbohydrate-LDL double whammy 9. July 2010 William Davis (14) Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles. The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall. --Small LDL particles are more adherent to glycosaminoglycans in the artery wall. --Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls. --Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL. --Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall. Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.) Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.) Here's a great demonstration of this phenomenon by Younis et al:"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference. Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation. So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal. To lose weight, prick your finger 8. July 2010 William Davis (45) We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day. So how can you stop triggering insulin?The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket. Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated. Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow. To do this, you will need:1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.) 2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece. 3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars. No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today. Iodine update 2. July 2010 William Davis (30) As the iodine experience grows, I've made several unique observations. Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.) Among the phenomena I've observed:1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development. 2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.3) Reversal of small goiters also occurs over about 6 months. 4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months. 5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet. 6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures. 7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L. Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females. All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are. << Older posts Newer posts >> Newer posts1 Near-death experience with nattokinase 16. May 2010 William Davis (22) This is a true story that I personally witnessed. A 60-some year old man heard that nattokinase "thinned the blood." So he had been taking it for the past 6 months. One week before he came to see me, he abruptly became quite breathless. He was unable to walk more than 20 feet or bend over to tie his shoes due to the breathlessness. He came to see me in the office. I was alarmed by how breathless he was without signs of heart failure or other obvious explanation. I sent him for an immediate CT pulmonary angiogram. Within 30 minutes, we had the diagnosis: a large "saddle" pulmonary embolus, meaning a large blood clot that straddled the right and left main pulmonary arteries. One wrong move and . . . bang! He would have been dead within a couple of minutes, since a large clot can completely occlude the large arteries feeding the lung, essentially corking any blood circuiting through the lungs and back to the left side of the heart. (Causing, incidentally, electromechanical dissociation, in which the heart keeps beating for a few minutes but no blood is being pumped. CPR can keep you alive for a few minutes, then it's over.) When I advised the patient of the diagnosis (after initiating the REAL anticoagulants), he said, "But I was taking nattokinase!" Exactly. Blood clots are no laughing matter. They are potentially fatal events. Betting your life on some company's advertisement is nothing short of foolish. Anyone who reads The Heart Scan Blog knows that I am an avid supporter of nutritional supplements. I even write articles and consult for the supplement industry. But I truly despise hearing unfounded marketing claims that some supplement companies will make in the pursuit of a fast buck. There is no doubt that we need better, safer methods to deal with dangerous blood clots, whether in the lung, pelvis, or other areas. But, before anyone takes a leap based on the extravagant marketing claims made by a supplement manufacturer, you want to be damn sure there are real data--not marketing claims, REAL data--before you use something like nattokinase in place of a proven therapy. Don't confuse the very interesting, though unpalatable, natto with nattokinase. Natto contains vitamin K2 and some other interesting compounds, including nattokinase. Blame the gluten? 14. May 2010 William Davis (17) Wheat is among the most destructive components of the human diet, a food that is responsible for inflammatory disease, diabetes, heart disease, several forms of intestinal diseases, schizophrenia, bipolar illness, ADHD, behavioral outbursts in autistic children . . . just to name a few. But why? Wheat is mostly carbohydrate. That explains its capacity to cause blood sugar to increase after eating, say, a turkey sandwich on whole wheat bread. The rapid release of sugars likely underlies its capacity to create visceral fat, what I call "wheat belly." But neither the carbohydrate nor the other components, like bran and B vitamins, can explain all the other adverse health phenomena of wheat. So what is it in wheat that, for instance, worsens auditory hallucinations in paranoid schizophrenics? Is it the gluten?First of all, what is gluten?Gluten protein is the focus of most wheat research conducted by food manufacturers and food scientists, since it is the component of wheat that confers the unique properties of dough, allowing a pizza maker to roll and toss pizza crust in the air and mold it into shape. The distinctive “doughy” quality of the simple mix of wheat flour and water, unlike cornstarch or rice starch, for instance, properties that food scientists call “viscoelasticity” and “cohesiveness,” are due to the gluten. Wheat is mostly carbohydrate, but the 10-15% protein content is approximately 80% gluten. Wheat without gluten would lose its unique qualities that make it desirable to bakers and pizza makers. Gluten is also the component of wheat most confidently linked to immune diseases like celiac. The structure of gluten proteins has proven frustratingly elusive to characterize, as it changes over time and varies from strain to strain. But an understanding of gluten structure may be part, perhaps most, of the answer to the question of why wheat provokes negative effects in humans. The term “gluten” encompasses two primary families of proteins, the gliadins and the glutenens. The gliadins, one of the protein groups that trigger the immune response in celiac disease, has three subtypes: a/ß-gliadins, ?-gliadins, and ?-gliadins. The glutenins are repeating structures, or polymers, of more basic protein structures. Beyond gluten, the other 20% or so of non-gluten proteins in wheat include albumins, prolamins, and globulins, each of which can also vary from strain to strain. In total, there are over 1000 other proteins that serve functions from protection of the grain from pathogens, to water resistance, to reproductive functions. There are agglutinins, peroxidases, a-amylases, serpins, and acyl CoA oxidases, not to mention five forms of glycerinaldehyde-3-phosphate dehydrogenases. I shouldn’t neglect to mention the globulins, ß-purothionin, puroindolines a and b, tritin, and starch synthases. As if this protein/enzyme smorgasbord weren’t enough, food processors have also turned to fungal enzymes, such as cellulases, glucoamylases, xylanases, and ß-xylosidases to enhance leavening and texture. Many bakers also add soy flour to enhance mixing and whiteness, which introduces yet another collection of proteins and enzymes.In short, wheat is not just a simple gluten protein with some starch and bran. It is a complex collection of biological material that varies according to its genetic code. While wheat is primarily carbohydrate, it is also a mix of gluten protein which can vary in structure from strain to strain, as well as a highly variable mix of non-gluten proteins. Wheat has evolved naturally to only a modest degree, but it has changed dramatically under the influence of agricultural scientists. With human intervention, wheat strains are bred and genetically manipulated to obtain desirable characteristics, such as height (ranging from 18 inches to over 4 feet tall), “clinginess” of the seeds, yield per acre, and baking or viscoelastic properties of the dough. Various chemicals are also administered to fight off potential pathogens, such as fungi, and to activate the expression of protective enzymes within the wheat itself to “inoculate” itself against invading organisms. From the original two strains of wheat consumed by Neolithic humans in the Fertile Crescent 9000 years ago (Emmer and Einkorn), we now have over 200,000 strains of wheat virtually all of which are the product of genetic manipulations that have modified the protein structure of wheat. The extraordinary complexity of wheat proteins have therefore created a huge black box of uncertainty in pinpointing which protein causes what. But there's an easy cure for the uncertainty: Don't eat it. Glycemic gobbledygook 13. May 2010 William Davis (14) The concept of glycemic index is meant to help determine what foods raise blood sugar a lot vs. what foods raise blood sugar a little. Dr. Jennie Brand-Miller's searchable database can be found here.I have to admit that glycemic index provided me with a sense of false assurance for some years. It screwed up my health until I came to understand the issues a lot better. For those of you just starting out in nutritional conversations, glycemic index (GI) represents a comparison of the blood glucose area-under-the-curve (AUC) over 2 hours after consuming 50 grams of the food in question compared to the AUC of glucose or white bread. Volunteers involved in developing these values are healthy people who are generally of normal weight. Glucose, by definition, has a GI of 100. An equal quantity of sucrose (50% glucose, 50% fructose) has a GI of 60, lower than glucose. An equal quantity of whole wheat bread has a GI of 68-77 (Yes: The GI of whole wheat is higher than sucrose). Non-carbohydrate foods, such as eggs or avocado, have no GI since they do not impact on blood glucose. Because the GI is also sensitive to how much carbohydrate is contained, the concept of Glycemic Load (GL) was introduced:GL = (GI x amount of carbohydrate) / 100GL is therefore the GI that incorporates the glycemic potential of the food of interest. GI does not vary with portion size; GL varies with portion size. Let's take whole wheat pasta, a food regarded by most people as a healthy choice. Whole wheat pasta has a GI of 55--fairly low--and a GL of 29. A serving of 180 g (approximately 6 oz cooked) provides 50 g carbohydrates. People who advocate that low-glycemic index foods would say that this is a desirable profile and should therefore replace high-glycemic index foods. I say WRONG. First of all, most of us are not slender 20-somethings. We will therefore not show the same response as a young, slender person (like the GI volunteers), but will show exagerrated blood sugar responses. So this much low-glyemic index whole wheat pasta will typically yield a blood sugar of 120-200 mg/dl in non-diabetic people, high enough to trigger glycation. Sure, a high-glycemic index food, such as white flour birthday cake with plenty of sugary icing, might trigger a blood sugar of 140-250 mg/dl, much worse. But that doesn't make the lower blood sugar following pasta any less bad--it's still terrible. Another issue: GI is assessed over a 2-hour timeline. What if blood sugar remains high in a sustained way, say, over 6 hours? That's precisely what whole wheat pasta will do: Keep blood sugar high for an extended period. So not only does a low-glycemic index food like pasta increase blood sugar in most of us extravagantly, it does so in a sustained way. Lastly, low-glycemic index pasta still triggers small LDL particles to an extreme degree, as I discussed in the previous Heart Scan Blog post, Small LDL: Complex vs. simple carbohydrates. Don't be false reassured by the notion of low GI or GL. In fact, I'd go so far as to say that NO glycemic index is a GOOD glycemic index (or load). The foods we want to dominate our diet are the foods that aren't even listed in the GI database. << Older posts Newer posts >> Newer posts12...232425262728293031...123124Older posts
There's no such thing as a "no-carb" diet 27. July 2010 William Davis (24) When I tell patients how I advise a wheat-free, cornstarch-free, sugar-free diet on the background of a low-carbohydrate diet, some people ask: "But can I live on a no-carb diet?"Well, there's no such thing as a "no-carb" diet. Low-carb, yes. No-carb, no.Here are the carbohydrate contents of various "low-carb" foods:Gouda cheese--3 oz contains 1.65 grams carbohydratesMozzarella cheese--1 cup contains 2.89 grams carbohydrates Walnuts--4 oz (56 nuts) contains 2.96 grams carbohydratesAlmonds--4 oz contains 1.38 grams carbohydratesSour cream--one-half cup contains 3.31 grams carbohydratesRed wine--3.5 oz glass contains 2.69 grams carbohydratesEggplant--1 cup cooked contains 8.33 grams carbohydratesGreen pepper--1 medium-sized raw contains 5.52 grams carbohydratesCucumber--1 medium contains 4.34 grams carbohydratesTomato--1 medium contains 4.82 grams carbohydrates (Nutrition data from USDA Nutrient Database)In other words, foods thought to be "low-carb" actually contain a modest quantity of carbohydrates. Such modest quantities of carbohydrates may not be enough to trip your blood sugar. But add up all the "low-carb" foods you consume over the course of a day and you can easily achieve 30 grams or more carbohydrates per day even without consuming any higher carbohydrate foods.
Why doesn't your doctor try to CURE diabetes? 21. July 2010 William Davis (88) Imagine you have breast cancer. You go to your doctor and she says, "As your pain worsens, we'll help you with pain medication. We'll fit you with a special bra to accommodate the tumor as it grows. That's all we're going to do.""What?" you ask. "You mean just deal with the disease and its complications, but you're not going to help me get rid of it . . . cure it?" It would be incredibly shocking to receive such advice. Then why is that the sort of advice given when you are diagnosed with diabetes? Say you go to the doctor. Lab values show a fasting blood sugar of 156 mg/dl, HbA1c (a reflection of your previous 60 days average glucose) of 7.1%. Both values show clear-cut diabetes. Your doctor advises you to 1) start the drug metformin, then 2) talk to the diabetic teaching nurse or dietitian about an American Diabetes Association (ADA) diet. The ADA diet prescribed encourages you to increase carbohydrates and cut fats at each meal and maintain a consistent intake so that you don't experience hypoglycemic (low blood sugar) episodes. You follow the diet, which causes you to gain 10-15 lbs per year, increasing your "need" for diabetes medication. You doctor adds Actos, then Januvia, then injections of Byetta. Three years and 34 lbs later, you are not responding well to the drug combination with blood sugars rarely staying below 200 mg/dl. You've developed protein in your urine ("proteinuria"), lost 30% of your kidney function, and you are starting to lose sensation in your feet. So the doctor replaces some of your medication with several insulin injections per day. This formula is followed millions of times per year in the U.S. So where along the way did your doctor mention anything about a "cure"?Adult diabetes is the one chronic disease that nobody cares to cure. Treat it, maintain control over blood sugars, but cure it? Most physicians say it's impossible. The tragedy is that diabetes is a curable condition. I've seen it happen many times. Physicians dedicated to curing diabetes like low-carb expert, Dr. Mary Vernon, have cured it countless times. Dr. Eric Westman and colleagues have been building the case for the carbohydrate-restricted cure for diabetes with studies such as this. In this last study, of the 8 participants on insulin + medications at the start of the study, 5 no longer required medications at the close of the study--they were essentially non-diabetic. I tell patients that diabetes, in fact, is a disease you choose to have or not to have--provided you are provided the right diet and tools. Sadly, rarely are diabetics told about the right diet and tools. That's why Cadbury Schweppes has been a major contributor to the American Diabetes Association, as are other processed food manufacturers and the drug industry, all who stand to profit from maintaining the status quo. The cure? Eliminate or at least dramatically reduce carbohydrates, the foods that increase blood sugar. Note: If you have diabetes and you are taking any prescription agents, such as glyburide, glipizide, insulin, and some others, you will need to discuss how to manage your medications if you reduce carbohydrates. The problem is finding a doctor or other resource to help you do this.
LDL pattern B 18. July 2010 William Davis (17) Here's a Q&A I stumbled on in the Forum of MedHelp, where people obtain answers from presumed health "experts." Question:My VAP test results in July 07 identified an LDL Pattern B. Overall results: Total 150 HDL 75 LDL 61 Trig 60 HDL-2 17 LP(a) 6.0 LDL Pattern B Medications: Lipitor 10mg Zetia 10mg Altace 10mg Atenolol 50mg Plavix 75mg Aspirin 81mg I had several heart attacks which resulted in CABG performed May 2000. I am a 53 year old white male , 6'1", 190 pounds, exercise every day, watch my diet and feel great. Everything looks OK except my LDL Pattern B. Is there any therapy to improve the Patten B? Answer from CCF, MD:Your results indicate an LDL pattern B, which generally indicates small atherogenic LDL particles which may cause increased risk for CAD. However, there are several problems with LDL patterning: 1) its unreliability (of LDL pattern testing ), 2) unclear clinical evidence regarding regarding the usefulness of LDL patterns and particle size. The majority of evidence regarding the progression of atherosclerosis is with LDL lowering and to an smaller extent HDL raising. All available clinical evidence shows that any particles in the VLDL, IDL, or LDL range are atherogenic, and there is no evidence that whether belonging to pattern A or B one is more atherogenic than others. Subclass studies have proliferated over the last few years, but many of these studies were funded or subsidized either by suppliers of the assays as a method to expand their use and move them into mainstream practice, or by pharmaceutical companies in an attempt to claim some advantage over other therapeutic agents. Thus, current data on LDL subclasses are at best incomplete and at worst misleading, suffering from publication bias, and now given the recent results of the Ensign et al. study, unreliable. Your LDL, and HDL are at goal. The Lpa level is still not clearly linked as a modifiable risk factor for CAD, although elevated levels are now know to be linked to stroke. Continue with your present treatments: aspirin, plavix, ateonol and altace are all essential medications. Wow. The extent of ignorance that pervades the ranks of my colleagues is frightening. Contrary to the response, LDL particle size assays are quite reliable and accurate. I've performed many thousands of lipoprotein assays and they yield reproducible and clinically believable results. For example, eliminate wheat, oats, cornstarch, and sugars and small LDL drops from 2400 nmol/L to 893 nmol/L (NMR)--huge drops. If repeated within a short period of time, the second measure will correspond quite closely. The data are also quite clear: Small LDL particles (i.e., "pattern B") are a potent predictor of cardiovascular events. What we lack are the treatment trials that show that reduction of small LDL results in reduced cardiovascular events. The reason for this is that small LDL research is not well-funded, since there is no prescription drug to treat small LDL, only nutritional means. Niacin (as Niaspan) is as close as it comes for a "drug" to reduce small LDL. But diet is far more effective. Given the questioner's fairly favorable BMI of 25.1 and his history of aggressive heart disease, it is virtually certain that he has what I call "genetic small LDL," i.e., small LDL that occur on a genetically-determined basis (likely due to variants of the cholesteryl-ester transfer protein, or CETP, or of hepatic lipase and others). Ignoring this man's small LDL will, without a doubt, consign him to a future of more heart attacks, stents, and bypass. Maybe by that time the data supporting the treatment of small LDL will become available.
What increases blood sugar more than wheat? 15. July 2010 William Davis (38) Take a look at these glycemic indexes (GI):White bread 69Whole wheat bread 72Sucrose 59Mars bar 68White rice 72Brown rice 66I've made issue in past of whole wheat's high GI--higher than white bread. Roughly in the same glycemic league as bread are shredded wheat cereal, brown rice, and a Mars candy bar.With few exceptions, wheat products have among the highest GIs compared to the majority of other foods. For instance:Kidney beans 29Chick peas 36Apple 39Ice cream 36Snickers Bar 40Yes, by the crazy logic of glycemic index, Snickers is a low-glycemic index food. While I do not believe that low GI makes a food good or desirable, since low GI foods still provoke high blood sugars, small LDL particles, trigger glycation, and other abnormal phenomena, they are clearly less obnoxious than the items in the first list. Take a look at this list:Cornflakes 80Rice cakes 80Rice Krispies 82Rice pasta, 92Instant potatoes 83Tapioca 81Starches that are dried and/or pulverized, such as cornstarch, potato starch, rice starch, and tapioca starch (cassava root) will increase blood sugar even more than wheat. Foods with these starches have GI's of 80-100. Cornstarch, potato starch, rice starch, and tapioca starch: Sound familiar? These are the main starches used in "gluten-free" foods. A hint of the high GI behavior of these dried starches is seen in the GI for cornflakes of 80.So remember: Wheat-free is not the same as gluten-free. Gluten-free identifies junk carbohydrates masquerading as healthy because they don't contain one unhealthy ingredient, i.e. wheat.
China fiction? 10. July 2010 William Davis (39) Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk. Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger. Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition. Her comments on the relationship of wheat to heart disease:Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease?
Carbohydrate-LDL double whammy 9. July 2010 William Davis (14) Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles. The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall. --Small LDL particles are more adherent to glycosaminoglycans in the artery wall. --Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls. --Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL. --Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall. Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.) Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.) Here's a great demonstration of this phenomenon by Younis et al:"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference. Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation. So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal.
To lose weight, prick your finger 8. July 2010 William Davis (45) We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day. So how can you stop triggering insulin?The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket. Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated. Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow. To do this, you will need:1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.) 2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece. 3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars. No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today.
Iodine update 2. July 2010 William Davis (30) As the iodine experience grows, I've made several unique observations. Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.) Among the phenomena I've observed:1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development. 2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.3) Reversal of small goiters also occurs over about 6 months. 4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months. 5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet. 6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures. 7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L. Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females. All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.
Near-death experience with nattokinase 16. May 2010 William Davis (22) This is a true story that I personally witnessed. A 60-some year old man heard that nattokinase "thinned the blood." So he had been taking it for the past 6 months. One week before he came to see me, he abruptly became quite breathless. He was unable to walk more than 20 feet or bend over to tie his shoes due to the breathlessness. He came to see me in the office. I was alarmed by how breathless he was without signs of heart failure or other obvious explanation. I sent him for an immediate CT pulmonary angiogram. Within 30 minutes, we had the diagnosis: a large "saddle" pulmonary embolus, meaning a large blood clot that straddled the right and left main pulmonary arteries. One wrong move and . . . bang! He would have been dead within a couple of minutes, since a large clot can completely occlude the large arteries feeding the lung, essentially corking any blood circuiting through the lungs and back to the left side of the heart. (Causing, incidentally, electromechanical dissociation, in which the heart keeps beating for a few minutes but no blood is being pumped. CPR can keep you alive for a few minutes, then it's over.) When I advised the patient of the diagnosis (after initiating the REAL anticoagulants), he said, "But I was taking nattokinase!" Exactly. Blood clots are no laughing matter. They are potentially fatal events. Betting your life on some company's advertisement is nothing short of foolish. Anyone who reads The Heart Scan Blog knows that I am an avid supporter of nutritional supplements. I even write articles and consult for the supplement industry. But I truly despise hearing unfounded marketing claims that some supplement companies will make in the pursuit of a fast buck. There is no doubt that we need better, safer methods to deal with dangerous blood clots, whether in the lung, pelvis, or other areas. But, before anyone takes a leap based on the extravagant marketing claims made by a supplement manufacturer, you want to be damn sure there are real data--not marketing claims, REAL data--before you use something like nattokinase in place of a proven therapy. Don't confuse the very interesting, though unpalatable, natto with nattokinase. Natto contains vitamin K2 and some other interesting compounds, including nattokinase.
Blame the gluten? 14. May 2010 William Davis (17) Wheat is among the most destructive components of the human diet, a food that is responsible for inflammatory disease, diabetes, heart disease, several forms of intestinal diseases, schizophrenia, bipolar illness, ADHD, behavioral outbursts in autistic children . . . just to name a few.

The extraordinary complexity of wheat proteins have therefore created a huge black box of uncertainty in pinpointing which protein causes what. But there's an easy cure for the uncertainty: Don't eat it.
Glycemic gobbledygook 13. May 2010 William Davis (14) The concept of glycemic index is meant to help determine what foods raise blood sugar a lot vs. what foods raise blood sugar a little. Dr. Jennie Brand-Miller's searchable database can be found here.I have to admit that glycemic index provided me with a sense of false assurance for some years. It screwed up my health until I came to understand the issues a lot better. For those of you just starting out in nutritional conversations, glycemic index (GI) represents a comparison of the blood glucose area-under-the-curve (AUC) over 2 hours after consuming 50 grams of the food in question compared to the AUC of glucose or white bread. Volunteers involved in developing these values are healthy people who are generally of normal weight. Glucose, by definition, has a GI of 100. An equal quantity of sucrose (50% glucose, 50% fructose) has a GI of 60, lower than glucose. An equal quantity of whole wheat bread has a GI of 68-77 (Yes: The GI of whole wheat is higher than sucrose). Non-carbohydrate foods, such as eggs or avocado, have no GI since they do not impact on blood glucose. Because the GI is also sensitive to how much carbohydrate is contained, the concept of Glycemic Load (GL) was introduced:GL = (GI x amount of carbohydrate) / 100GL is therefore the GI that incorporates the glycemic potential of the food of interest. GI does not vary with portion size; GL varies with portion size. Let's take whole wheat pasta, a food regarded by most people as a healthy choice. Whole wheat pasta has a GI of 55--fairly low--and a GL of 29. A serving of 180 g (approximately 6 oz cooked) provides 50 g carbohydrates. People who advocate that low-glycemic index foods would say that this is a desirable profile and should therefore replace high-glycemic index foods. I say WRONG. First of all, most of us are not slender 20-somethings. We will therefore not show the same response as a young, slender person (like the GI volunteers), but will show exagerrated blood sugar responses. So this much low-glyemic index whole wheat pasta will typically yield a blood sugar of 120-200 mg/dl in non-diabetic people, high enough to trigger glycation. Sure, a high-glycemic index food, such as white flour birthday cake with plenty of sugary icing, might trigger a blood sugar of 140-250 mg/dl, much worse. But that doesn't make the lower blood sugar following pasta any less bad--it's still terrible. Another issue: GI is assessed over a 2-hour timeline. What if blood sugar remains high in a sustained way, say, over 6 hours? That's precisely what whole wheat pasta will do: Keep blood sugar high for an extended period. So not only does a low-glycemic index food like pasta increase blood sugar in most of us extravagantly, it does so in a sustained way. Lastly, low-glycemic index pasta still triggers small LDL particles to an extreme degree, as I discussed in the previous Heart Scan Blog post, Small LDL: Complex vs. simple carbohydrates. Don't be false reassured by the notion of low GI or GL. In fact, I'd go so far as to say that NO glycemic index is a GOOD glycemic index (or load). The foods we want to dominate our diet are the foods that aren't even listed in the GI database.
