For the sake of convenience: Commercial sources of prebiotic fibers 3. May 2015 William Davis (0) Our efforts to obtain prebiotic fibers/resistant starches, as discussed in the Cureality Digestive Health Track, to cultivate healthy bowel flora means recreating the eating behavior of primitive humans who dug in the dirt with sticks and bone fragments for underground roots and tubers, behaviors you can still observe in extant hunter-gatherer groups, such as the Hadza and Yanomamo. But, because this practice is inconvenient for us modern folk accustomed to sleek grocery stores, because many of us live in climates where the ground is frozen much of the year, and because we lack the wisdom passed from generation to generation that helps identify which roots and tubers are safe to eat and which are not, we rely on modern equivalents of primitive sources. Thus, green, unripe bananas, raw potatoes and other such fiber sources in the Cureality lifestyle. There is therefore no need to purchase prebiotic fibers outside of your daily effort at including an unripe green banana, say, or inulin and fructooligosaccharides (FOS), or small servings of legumes as a means of cultivating healthy bowel flora. These are powerful strategies that change the number and species of bowel flora over time, thereby leading to beneficial health effects that include reduced blood sugar and blood pressure, reduction in triglycerides, reduced anxiety and improved sleep, and reduced colon cancer risk. HOWEVER, convenience can be a struggle. Traveling by plane, for example, makes lugging around green bananas or raw potatoes inconvenient. Inulin and FOS already come as powders or capsules and they are among the options for a convenient, portable prebiotic fiber strategy. But there are others that can be purchased. This is a more costly way to get your prebiotic fibers and you do not need to purchase these products in order to succeed in your bowel flora management program. These products are therefore listed strictly as a strategy for convenience. Most perspectives on the quality of human bowel flora composition suggest that diversity is an important feature, i.e., the greater the number of species, the better the health of the host. There may therefore be advantage in varying your prebiotic routine, e.g., green banana on Monday, inulin on Tuesday, PGX (below) on Wednesday, etc. Beyond providing convenience, these products may introduce an added level of diversity, as well. Among the preparations available to us that can be used as prebiotic fibers:PGXWhile it is billed as a weight management and blood sugar-reducing product, the naturally occurring fiber--α-D-glucurono-α-D-manno-β-D-manno- β-D-gluco, α-L-gulurono-β-D mannurono, β-D-gluco-β- D-mannan--in PGX also exerts prebiotic effects (evidenced by increased fecal butyrate, the beneficial end-product of bacterial metabolism). PGX is available as capsules or granules. It also seems to exert prebiotic effects at lower doses than other prebiotic fibers. While I usually advise reaching 20 grams per day of fiber, PGX appears to exert substantial effects at a daily dose of half that quantity. As with all prebiotic fibers, it is best to build up slowly over weeks, e.g., start at 1.5 grams twice per day. It is also best taken in two or three divided doses. (Avoid the PGX bars, as they are too carb-rich for those of us trying to achieve ideal metaobolic health.)PrebiotinA combination of inulin and FOS available as powders and in portable Stick Pacs (2 gram and 4 gram packs). This preparation is quite costly, however, given the generally low cost of purchasing chicory inulin and FOS separately. AcaciaAcacia fiber is another form of prebiotic fiber. RenewLife and NOW are two reputable brands. Isomalto-oligosaccharidesThis fiber is used in Quest bars and in Paleo Protein Bars. With Quest bars, choose the flavors without sucralose, since it has been associated with undesirable changes in bowel flora. There you go. It means that there are fewer and fewer reasons to not purposefully cultivate healthy bowel flora and obtain all the wonderful health benefits of doing so, from reduced blood pressure, to reduced triglycerides, to deeper sleep. Disclaimer: I am not compensated in any way by discussing these products.
How Not To Have An Autoimmune Condition 20. April 2015 William Davis (0) Autoimmune conditions are becoming increasingly common. Estimates vary, but it appears that at least 8-9% of the population in North America and Western Europe have one of these conditions, with The American Autoimmune Related Diseases Association estimating that it’s even higher at 14% of the population. The 200 or so autoimmune diseases that afflict modern people are conditions that involve an abnormal immune response directed against one or more organs of the body. If the misguided attack is against the thyroid gland, it can result in Hashimoto’s thyroiditis. If it is directed against pancreatic beta cells that produce insulin, it can result in type 1 diabetes or latent autoimmune diabetes of adults (LADA). If it involves tissue encasing joints (synovium) like the fingers or wrists, it can result in rheumatoid arthritis. It if involves the liver, it can result in autoimmune hepatitis, and so on. Nearly every organ of the body can be the target of such a misguided immune response. While it requires a genetic predisposition towards autoimmunity that we have no control over (e.g., the HLA-B27 gene for ankylosing spondylitis), there are numerous environmental triggers of these diseases that we can do something about. Identifying and correcting these factors stacks the odds in your favor of reducing autoimmune inflammation, swelling, pain, organ dysfunction, and can even reverse an autoimmune condition altogether.Among the most important factors to correct in order to minimize or reverse autoimmunity are:Wheat and grain eliminationIf you are reading this, you likely already know that the gliadin protein of wheat and related proteins in other grains (especially the secalin of rye, the hordein of barley, zein of corn, perhaps the avenin of oats) initiate the intestinal “leakiness” that begins the autoimmune process, an effect that occurs in over 90% of people who consume wheat and grains. The flood of foreign peptides/proteins, bacterial lipopolysaccharide, and grain proteins themselves cause immune responses to be launched against these foreign factors. If, for instance, an autoimmune response is triggered against wheat gliadin, the same antibodies can be aimed at the synapsin protein of the central nervous system/brain, resulting in dementia or cerebellar ataxia (destruction of the cerebellum resulting in incoordination and loss of bladder and bowel control). Wheat and grain elimination is by far the most important item on this list to reverse autoimmunity.Correct vitamin D deficiencyIt is clear that, across a spectrum of autoimmune diseases, vitamin D deficiency serves a permissive, not necessarily causative, role in allowing an autoimmune process to proceed. It is clear, for instance, that autoimmune conditions such as type 1 diabetes in children, rheumatoid arthritis, and Hashimoto’s thyroiditis are more common in those with low vitamin D status, much less common in those with higher vitamin D levels. For this and other reasons, I aim to achieve a blood level of 25-hydroxy vitamin D level of 60-70 ng/ml, a level that usually requires around 4000-8000 units per day of D3 (cholecalciferol) in gelcap or liquid form (never tablet due to poor or erratic absorption). In view of the serious nature of autoimmune diseases, it is well worth tracking occasional blood levels.Supplement omega-3 fatty acidsWhile omega-3 fatty acids, EPA and DHA, from fish oil have proven only modestly helpful by themselves, when cast onto the background of wheat/grain elimination and vitamin D, omega-3 fatty acids compound anti-inflammatory benefits, such as those exerted via cyclooxygenase-2. This requires a daily EPA + DHA dose of around 3600 mg per day, divided in two. Don’t confuse EPA and DHA omega-3s with linolenic acid, another form of omega-3 obtained from meats, flaxseed, chia, and walnuts that does not not yield the same benefits. Nor can you use krill oil with its relatively trivial content of omega-3s.Eliminate dairyThis is true in North America and most of Western Europe, less true in New Zealand and Australia. Autoimmunity can be triggered by the casein beta A1 form of casein widely expressed in dairy products, but not by casein beta A2 and other forms. Because it is so prevalent in North America and Western Europe, the most confident way to avoid this immunogenic form of casein is to avoid dairy altogether. You might be able to consume cheese, given the fermentation process that alters proteins and sugar, but that has not been fully explored.Cultivate healthy bowel floraPeople with autoimmune conditions have massively screwed up bowel flora with reduced species diversity and dominance of unhealthy species. We restore a healthier anti-inflammatory panel of bacterial species by “seeding” the colon with high-potency probiotics, then nourishing them with prebiotic fibers/resistant starches, a collection of strategies summarized in the Cureality Digestive Health discussions. People sometimes view bowel flora management as optional, just “fluff”–it is anything but. Properly managing bowel flora can be a make-it-or-break-it advantage; don’t neglect it.There you go: a basic list to get started on if your interest is to begin a process of unraveling the processes of autoimmunity. In some conditions, such as rheumatoid arthritis and polymyalgia rheumatica, full recovery is possible. In other conditions, such as Hashimoto’s thyroiditis and the pancreatic beta cell destruction leading to type 1 diabetes, reversing the autoimmune inflammation does not restore organ function: hypothyroidism results after thyroiditis quiets down and type 1 diabetes and need for insulin persists after pancreatic beta cell damage. But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery
Five Powerful Ways to Reduce Blood Sugar 4. April 2015 William Davis (0) Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess. If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics. Among the most powerful and effective strategies to reduce blood sugar:1) Eat no wheat nor grainsRecall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.2) Add no sugars, avoid high-fructose corn syrupThis should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.3) Vitamin DBecause vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.4) Restore bowel floraAs cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)5) ExerciseBlood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health. This is our core mission in Cureality. A nice side benefit: information from Cureality is not accompanied by advertisements from Merck, Pfizer, Kelloggs, Kraft, or Cadbury Schweppes.
Cureality App Review: Breathe Sync 7. March 2015 William Davis (0) Biofeedback is a wonderful, natural way to gain control over multiple physiological phenomen Don't overdo the vitamin D 17. December 2006 William Davis (1) As time passes and I advise more and more people to supplement vitamin D, I gain increasing respect for this powerful "vitamin". I am convinced that vitamin D replacement is the reason for a recent surge in our success rates in dropping CT heart scan scores. I believe it is also explains the larger drops we've been witnessing lately--20-30%. But vitamin D can be overdone, too. Too much of a good thing . . .Despite being labeled a "vitamin", cholecalciferol is actually a hormone. Vitamins are obtained from food and you can thereby develop deficiencies because of poor intake. Deficiency of vitamin C, for instance, arises from a lack of vegetables and fruits. Vitamin D, on the other hand, is nearly absent from food. The only naturally-occuring source is oily fish like salmon and sardines. Milk usually has a little (100 units per 8 oz) because milk producers have been required by law to put it there to reduce the incidence of childhood rickets. A woman came to me with a heart scan score of nearly 3800, the highest score I've every seen in a woman. (Record for a male >8,000!) She was taking vitamin D by prescription from her family doctor but at a dose of 150,000 units per week, or approximately 21,000 units per day. This had gone on for about 3-4 years. This may explain her excessive coronary calcium score. Interestingly, she had virtually no lipoprotein abnormalities identified, which by itself is curious, since most people have some degree of abnormality like small LDL. Obviously, I asked her to stop the vitamin D. Should you be afraid of vitamin D? Of course not. If your neighbor is an alcoholic and has advanced cirrhosis, does that mean you shouldn't have a glass or two of Merlot for health and enjoyment? It's a matter of quantity. Too little vitamin D and you encourage coronary plaque growth. Too much vitamin D and you trigger "pathologic calcification", or the deposition of calcium in inappropriate places and sometimes to extreme degrees, as in this unfortunate woman.Ideally, you should have your doctor check your 25-OH-vitamin D3 blood levels twice a year in summar and in winter. We aim for a level of 50 ng/ml, the level at which the phenemena of deficiency dissipate.
"It must have been the statin" 13. December 2006 William Davis (0) After four years of trying, Randy finally reduced her heart scan score. It not only dropped, it plummeted. After four previous scans that showed 25% or more increases, she'd finally dropped her score 23%. (I Blogged about Randy's case a few weeks ago.)Randy also works for a cardiologist. When she told him that she had reversed her coronary plaque and reduced her heart scan score by 23%, he said, "It must have been the statin agent."Randy was indeed on a statin drug at a low dose. But she also had taken great efforts in exercise, food choices, fish oil, and vitamin D. In fact, her score had progressed dramatically while she was taking the drug. Put simply, it was not the statin. But that is the mindset of the conventionally thinking cardiologist. Stent, bypass, or statin drug--what else is there? Even with crystal clear evidence for coronary plaque regression, they refuse to acknowledge that tools that are not in their everyday consciousness could have achieved so spectacular a result. Given a choice, 9 out of 10 cardiologists would rather put a stent in and walk away $2000 richer for an hour of work. Don't allow them to have this choice. Take control now.
12. December 2006 William Davis (0) Statin Drugs May Help the Healthy:Cholesterol-Lowering Statin Drugs May Benefit People Without Heart Disease That's the headline on WebMD, reporting the findings of a recent study published in the Archives of Internal Medicine. In reality, it wasn't really a study at all, but a re-analysis of previously published data, a so-called meta-analysis. Nonetheless, the University of Toronto group re-analyzed the results of several studies, pooling data on 28,000 people, none of whom had known coronary disease. The results were similar to the results of the studies that were reported individually: a 29% reduction in heart attack and other "events" in people taking statin drugs. What's surprising to me is this notion that statins, or any other treatment for that matter, prevent heart attack in people without heart disease. This is idiotic. Of course they had coronary heart disease. You can't have a heart attack in the absence of coronary disease. (There are very rare exceptions, like cocaine users, who experience coronary spasm from the drug). What the study shows is that people with unrecognized heart disease experienced a reduction in heart attack. What it also means is that many, many people truly without heart disease were unnecessarily treated. As you'd predict, the drug manufacturers love this sort of broad, untargeted use of their drugs. It's an approach that brings in billions of dollars of revenues. The article on WebMD, in fact, was accompanied by three ads for various cholesterol drugs on this single page story.What if only people with heart disease, as identified by CT heart scan scores, were treated? You would indeed witness an even larger reduction in heart attack risk, because the group receiving treatment both has the disease and is thereby at greater risk. Treatment should yield even greater risk reduction than treating broad groups who superficially appear to not have heart disease. Ignore this nonsense about statin drugs reducing heart attack risk in people without heart disease. If you don't look for it, you won't know you have it. Once again, you can be lots smarter than the media. Get a heart scan and find out if your risk is worth reducing.
Heart attack guaranteed 10. December 2006 William Davis (0) What if you knew for a fact that your risk for heart attack was 100% by, say, age 58? This is indeed true for many people, though at age 60, 65, 70--or 45.In other words, unless something were done about the causes of heart disease, you would inevitably suffer a heart attack at 58.What sort of action could you take at age 45?Obviously, not smoking is an absolute requirement. Continue and you may as well start getting your affairs together.How about exercising and eating a generally healthy diet? Will your risk be reduced to zero? No. It might be reduced 20-30%, depending on genetic factors.How about a statin drug? Watch TV ads during Oprah, and you might think it's a cure. But in reality, while it is a financial bonanza for the drug manufacturers, it will reduce risk for heart attack by 30%.(Note that risk reduction by following multiple strategies is not necessarily additive. In other words, if you have a healthy lifestyle and take a statin agent, is risk reduced 60% (30 + 30)? No, because the effects may overlap.)So, eating healthy, exercising, and taking a statin drug might reduce risk 35-40%, maybe 50% in the best case scenario. Would you be satisfied? Most would not.Add fish oil at a truly therapeutic dose. Risk reduction by itself: 28%.Add niacin or other strategies for correction of your individual, specific causes of heart disease: Now we're up to 90% reduction.Throw in a tracking process to prove whether or not atherosclerotic plaque has progressed or reversed. Now we're approaching 100% if plaque reverses. The only way I know how to track plaque is through CT heart scans. What other test is readily available to you with low radiation exposure, yet is relatively inexpensive and precise? It certainly is not stress testing, heart catheterization, CT angiograms, or other techniques. Cholesterol won't tell you. Besides CT heart scans, there's nothing else I know of.Let's fact it: For many people, uncorrected risk for heart attack is truly 100% at some age. Take action while you can.That, in a nutshell, is the Track Your Plaque program.
Heart scan curiosities 3 10. December 2006 William Davis (7) This is a sample image from the heart scan of a 54-year old, 212 lb, 5 ft 2 inch woman. The heart is the whitish-gray in the center; lungs are the dark (air-filled) areas on either side of the heart. Note the massive amount of surrounding gray tissues that encircles the heart and lungs. This is fat. At this weight, the diameter of total fat exceeds the combined diameter of the heart and lungs. If we were to show the abdomen, there would be even more fat. (The image shows the body not well centered because the technologist centers the heart, since this is, after all, a heart scan.)This is a 55-year old, 151 lb, 5 ft 4 inch woman. Note the contrast in the quantity of fat tissue surrounding the chest, a much more normal appearance. Note that this woman is still around 25 lb over ideal weight, but not to the extreme degree of the woman above.Another curious observation: Note the more whitish streaking in the heavier woman's lungs. Heart scans are performed while holding a deep inspiration (a deep breath inwards), mostly to eliminate lung respiratory motion during image acquisition. Nonetheless, the heavier woman's lungs are not as fully expanded as the more slender woman. In other words, the heavier woman cannot inflate her lungs as effectively as the thinner woman. Ever notice how breathless heavy people are? Some of this effect is just being out of shape. But there's also the added effect of the abdominal fat exerting upwards compression on the lung tissues, and the constrictive effect of the encircling fat mass. At the beginning of inspiration, the chest fat exerts the resistance of inertia to inspiration that is absent, or less, in a slender person. With each breath, the heavy woman must move 50 lbs or so of surrounding fat mass just to inhale. The heavier woman is, in effect, suffocating herself in fat. The distortions to the human body incurred by extreme weight gain are both fascinating and shocking. I hope you're breathing easily.
The shameful "standard of care" 10. December 2006 William Davis (1) John's initial heart scan four years ago showed a score of 329. His physician prescribed Zocor for a somewhat high LDL cholesterol. One year later, John asked for another scan. His score: 385, a 17% increase. John exercised harder and cut his fat intake. This past fall--3 years after his last scan--John had yet another heart scan. Score: 641, a 66% increase over the last scan, all the while on Zocor. John sought an opinion from a reputable cardiologist. He concurred with the prescription of Zocor and advised annual stress tests. That's it. Followers of the Track Your Plaque approach know that the expected uncorrected rate of increase in heart scan score is 30% per year. On Zocor or other cholesterol reducing statin agent, a common rate of growth is between 18-24% per year--better but not great. Plaque growth is certainly not stopped. But that is the full extent of interest and responsibility of your cardiologist. Prescribe a statin drug, perform a stress test, and the full extent of his obligation has been fulfilled. In legal terms, your physician has met the prevailing"standard of care". No more, no less.In other words, the prevailing standard of care falls shamefully short of what is truly possible. For the majority of the motivated and interested, coronary plaque reversal--reduction of your heart scan score--should be the standard aimed for. It's not always achievable, but it is so vastly superior to the prescribe statin, wait for heart attack approach endorsed by most cardiologists.
Heart scan curiosities 2 9. December 2006 William Davis (2) This is an example of a so-called "hiatal hernia", meaning the stomach has migrated through the diaphragmatic hiatus into the chest--the stomach is literally in the chest. This example is an unusually large one. Hiatal hernias can cause chest pain, indigestion, and a variety of other gastrointestinal complaints. Heart scans are reasonably useful to screen for this disorder, though very small ones could escape detection by this method. Sometimes, you can actually hear the gurgling of stomach contents (the common "growling" stomach) by listening to the chest. Large ones like this actually crowd your heart (the gray structure above the circled hernia), irritating it and even causing abnormal rhythm disorders. The dense dark material within the hernia represents lunch.I would not advocate CT heart scans as a principal method to make a diagnosis, but sometimes it just pops up during a heart scan and we pass it on to the person scanned.
Vitamin D: New Miracle Drug 6. December 2006 William Davis (0) At the meetings of the American Society of Bone and Mineral Research, Dr. Bruce Troen of the University of Miami detailed his views on the extraordinary benefits of vitamin D replacement. He also talked about the enormous problem of unrecognized vitamin deficiency.“There’s a huge epidemic of hypovitaminosis D, and the real key here is not just that it’ll benefit you from a bone and neuromuscular standpoint, but if you correct hypovitaminosis D and the corresponding secondary hyperparathyroidism, then you’re going to decrease prostate cancer, colon cancer—actually “up to 17 different cancers, breast cancer included.”Unfortunately, Dr. Troen did not talk much about the heart benefits of vitamin D, likely since the data is scant, nearly non-existent. However, if the Track Your Plaque experience means anything, I predict that vitamin D replacement will become among the most powerful tools you can use to gain control over coronary plaque. Read the text of a report from the Internal Medicine World Report to read more of Dr. Troen's comments. http://www.imwr.com/article.php?s=IMWR/2006/11&p=40
Heart disease "reversal" by stress test 5. December 2006 William Davis (3) Here's an interesting example of a 71-year old man who achieved "reversal" of an abnormality by a nuclear stress test. This man underwent bypass surgery around 10 years ago, two stents three years ago. A nuclear stress test in April, 2005 showed an area of poor blood flow in the front of the heart. On the images, normal blood flow is shown by the yellow/orange areas. poor or absent blood flow is shown by the blue/purple areas within the white outline. Now, I can tell you that this man is no paragon of health. He's only accepted limited changes in his otherwise conventional program--in other words, someone who I'd be shocked achieved true reversal of his heart disease. (I didn't have him undergo any CT heart scans because of the difficulties in scoring someone who has undergone bypass surgery and stents, and because of limited motivation. True plaque reversal is for the motivated.)This patient did, however, accept adding fish oil and niacin to his program.Nonetheless, stress testing can be helpful as a "safety check". Here's the follow-up stress test: You'll notice that the blue/purple areas of poor blood flow have just about disappeared. This occurred without procedures. Does this represent "reversal"? No, it does not. It does represent reversal of this phenomenon of poor flow. It does not represent reversal of the plaque lining the artery wall. That's because improvement of flow, as in this man, can be achieved with relatively easy efforts, e.g., improvement in diet, statin drugs, blood pressure control, etc. True reversal or reduction of coronary plaque, however, is tougher. If blood flow is improved, who cares whether plaque shrinks? Does it still matter? It does. That's because the "event" that gets us in trouble is not progressive reduction in blood flow, but "rupture" of a plaque. A reduction in plaque--genuine reversal--is what slashes risk of plaque rupture.
