Glucomania

As I suggested in a previous Heart Scan Blog post, a glucose meter is your best tool to:

1) Lose weight
2) Cure diabetes
3) Reduce or eliminate small LDL particles
4) Achieve anti-aging or age-slowing effects


But it means getting hold of a glucose meter and applying it in a very different way.

Diabetics typically check fasting morning glucose and again several times during the day to assess medication effects. But you and I can measure blood glucose to assess the immediate effects of food choices--two very different approaches.

The concept is simple: Check a blood glucose just prior to a food or meal of interest, then one hour after finishing.

Let's take two hypothetical breakfasts. First, oatmeal, a so-called "low-glycemic index" food. Slow-cooked, stone ground oatmeal with skim milk, a handful of walnuts, just a few blueberries.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 175 mg/dl

I made those numbers up, but this is a fairly typical response for many adults. (This is why "low-glycemic index" is an absurd notion.) This kind of response causes 1) glycation, the adverse effects of glucose modification of proteins that leads to cataracts, kidney disease, cartilage damage and arthritis, atherosclerosis, skin wrinkles, etc., 2) high insulin response that cascades into fat deposition, especially visceral fat ("wheat belly"), and 3) glucotoxicity, i.e., direct damage to the pancreas that can, over years, lead to diabetes.

Next day, let's try a breakfast of 3-egg omelet made with green peppers, sundried tomatoes, and olive oil.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 93 mg/dl

This is a meal of virtually zero-glycemic index. This kind of response triggers none of the effects experienced following the oatmeal. Repeated over time and you fail to trigger glycation, you stop provoking insulin, and visceral fat mobilizes rather than accumulates: you lose weight, particularly around the middle.

We therefore aim to keep the one-hour blood glucose 100 mg/dl or less. If you start with a high fasting blood glucose of, say, 118 mg/dl, then we aim to keep the one-hour after-eating blood glucose no higher than the pre-meal.

It works. Plain and simple.

This makes the primary care docs crazy: "How dare you check your blood sugar! You're not diabetic." In truth, blood glucose meters are relatively simple devices to use. The test strips and lancets will cost a few bucks. (The meters themselves are either low-cost or free, just like Gillette sometimes sends you a beautiful new razor for free but expects you to buy the blades). These are direct-to-consumer products. While a prescription written by your doctor for a glucose meter and supplies helps insurance cover the costs, you can easily get these devices without a prescription. Some stores, like Target, keep their devices out on the shelves with the shampoo and bath soap.

Warning: Anyone taking diabetes drugs will have to consult with their doctors about the safety of such an approach. Because this approach can actually cure diabetes in some people, if you are taking some diabetes drugs, especially glyburide, glipidize, and glimepiride, you can experience dangerously low blood sugars, just as any non-diabetic taking these drugs would.

    Had a bowl of oatmeal less than one hour ago. Old-fashioned oats, artificial sweetener, cinnamon. Now I am wiped out. Tired, sleepy. I don't even need a glucose meter to tell me the oatmeal reeked havoc on my blood sugar.

    I always feel this way after eating certain carbs. Used to think old-fashioned oatmeal was okay. But it's just not. Not for me anyway. By the way, I'm hypoglycemic.

    Most drug stores including Walmart and Target carry a small disposable meter that looks like a 35mm film bottle.  Very cheap and includes 50 test strips.  Next cheapest I've found is the Walmart ReliOn Ultima meter which is around $9 and you buy the strips at the Pharmacy (only since people steal them) for around $39 for 100.  When I first started Primal, my sugar readings were all over the place and then within 3-4 months of eating low-carb my reading became really stable all day long.  I think I had to burn through my over abundant glycogen stores first (it was mostly causing high waking pre-breakfast readings).

    I'm going to try this with the BG meter we use for our diabetic cat. It measures in mmol/L and the recommended BG targets are 4.0-7.0 before meals/5.0-10.0 2hrs. after. (for humans)
    Is this similar to your recommendation of100 mg/d,l Dr Davis?

    Just a "heads up" for others.  I ordered the Walmart Relion BG meter ($9) and a supply of strips and lancets online only to have Walmart CANCEL the BG meter (no reason available) and send me the strips and lancets (which I will have to return as they are useless to me without the Relion BG meter).  Walmart's website still says the BG meters are "in stock" when clearly they are not and customer service had no explanation for that either.

    I'll visit your earlier post to find a comparable meter.

    Dr. Davis: "This is why low-glycemic index is an absurd notion."

    Does this mean the Dreamfields pasta claim of being low-carb is misleading, at best?

    I've been contemplating trying it, but fear it really isn't low carb.

    i am curious about the effect that the oatmeal that i sometimes eat would have on my blood glucose levels.

    i take 3 cups of raw oats, soak them in warm water with 8 tablespoons of raw whey and add 2 heaping tablespoons of organic buckwheat flour and let them soak for 24 hours. drain and rinse thoroughly. pour the oats into a baking casserole dish and add some coconut oil, blueberries, pure vanilla, cinnamon, buttermilk. bake at 350 for 40 minutes.

    the result is a very delicious and highly altered form of oats. the whey and buckwheat drastically reduce the phytic acid and 'ferment' or predigest the oats. when it's done, i just add a couple spoons of pasture butter and enjoy. i've noticed a significant change in texture as a result. the oats are no longer firm. they feel quite 'broken down' and they do not sit in my stomach like a brick.

    why go through all that trouble? well... you should taste it. it is quite the treat.

    Desia,

    I'm diabetic and from the UK where we measure blood glucose in mmol/L - to convert from mg/dl to mmol/L just divide by 18 - so 100 is 5.5. Multiply by 18 to convert your mmol/L to mg/dl.

    Oatmeal and other high-carb foods won't cause blood sugar spikes if you are lean, get regular exercise,  eat high-carb foods on a regular basis, and don't have health problems. All 4 of the above conditions must be met. In particular, you MUST exercise, though the exerciser doesn't have to be lengthy.

    I find keeping my bodyfat under 15% (I'm a 50 year-old male, women would have a higher percentage) and doing 5 to 10 minutes of one-legged squats, which gets my blood pumping and is much more convenient than running, is enough to keep my insulin sensitivity high enough to avoid blood sugar surges.

    Yesterday, for example, I had a single large meal in the late afternoon, due to being too busy to eat most of the day: a half can of salmon, a large salad, 300g (dry) of cooked oats mixed with about 6 grams of cinnamon all eaten within about 30 minutes. My blood sugar never exceeded 110 mg/dL during the subsequent 3 hours (I measured every 30 minutes) and eventually fell back to the normal level of about 85.

    When I experimented with a paleo diet for a while, my insulin sensitivity plummeted, so that when I broke the paleo regime temporarily and ate a mere 100g (dry) of cooked oats, my blood sugar skyrocketed to 195 mg/dL 30 minutes later. And note that those oats were eaten together with 2 eggs and some veggies, which would normally tend to mute the glycemic index as opposed to eating oats by themselves. Evidently, what happened while eating paleo is that my body's cells had down-regulated their insulin sensitivity. This makes sense, since there is no need for high insulin sensitivity when eating paleo, and the greater danger under these conditions is low blood sugar rather than high blood sugar. Only when glucose is abundant (regularly eating a high carb diet) does the body upregulate insulin sensitivity. But the upregulation won't occur if the body is fat or doesn't get regular exercise. And, of course, it obviously won't occur for someone with a "burned out" pancreas, such as Type II diabetics supposedly have.

    Has there been any studies citing any differences in regular oats versus soaking/sprouted oats? I wonder if the neutralizing of the phytic acid that helps in digestions would also help the way the body breaks down the oats and, therefore, insulin response.

    Jeff -

    I have used Dreamfields for about 6 months now.  They claim the carbs are "locked up" and can't be digested.  I have found they do not affect blood glucose like regular pasta would.

    However they are still wheat, which has it's own problems even if the special processing prevents blood glucose spikes. I still have it once or twice a month when the rest of my "non-low carb" family has pasta, but I know I have to quit wheat all together soon, just hard to do. For now it's the lesser of two evils.

    It's dangerous to talk about "curing" diabetes with a low-carb diet. Someone with type 2 who goes on a LC diet may be able to maintain normal blood sugar levels as long as s/he stays on the diet. But the diabetes is not cured. Returning to a standard American diet would result in high blood sugar again.

    A diabetes cure would mean you could eat cereal, skim milk, orange juice, toast, and jam and keep your blood sugar levels normal.

    The danger of telling someone he/she is cured is that the person will believe it, will return to a regular diet, and will stop testing, not realizing how high blood sugars are and will end up in a worse situation than he/she started with.

    I enjoy this blog, but I do frequently agree with those who say that the grandiose effects of eating grains that you present are often times found more common place in people with metabolic problems. For example, while I was in college, I had a dorm mate who read some random article about gluten and suddenly believed herself to be suffering from Celiac Disease. My friends and I labeled her an hypochondriac, going so far as feeding her a deadly, lethal oatmeal cookie (gasp!) which we passed off as consisting of "a grain-like substance produced from the dried roots of a Japanese plant." My dorm mate ate the cookie and low and behold - nothing. Weeks prior she claimed to have taken a few bites of Frosted Mini Wheats in the cafeteria and subsequently suffered a debilitating pain in her stomach. Moral of the story is that her fear of gluten and the pain she felt from consuming Frosted Mini Wheats were purely psychosomatic.

    I guess what I'm at getting at is you provide good information, but often times the entries you write are reminiscent of the blogs/journals/prose/essays written by individuals such as the Unibomber. In a half-serious, half-jocular manner, I always feel like one day I'll read/hear in the news, "Man opens [gun] fire within an oatmeal factory," and [to no one's surprise] it'll be you. I'm not accusing you of actually perpetuating such an act, but you write with such vigor about something like wheat/grains, and it gives off the "vibe" that you are harboring some hardcore resentment.

    Once again, I enjoy your overall blog, but your hasty generalizations and confusing cause-and-effect can be misleading and overly exaggerated.

    Hi, Steve--

    Actually, the same advice applies to all forms of diabetes. Type 1 and "intermediate" types, i.e., slender people with diabetes, LADA, etc., can still follow a similar program with equally extravagant results.

    However, the blood sugar tightrope is much more difficult to walk for these people and should be undertaken with the assistance of the (sadly, rare) assistance of a knowledgeable expert in doing so.

    As much as this wheat-free idea kills me, I'm going to try to at least quit my sweetened cereal habit each morning. My fasting sugar is good - 81, but my triglycerides are still monstrous at 292 even with niacin and fish oil. On a semi-related matter, I confirmed for myself that dry Vitamin D doesn't work. I've been using Life Extension brand cholecalciferol 5,000 units a day for months, and my levels barely rose - from 33 to 36. Got a shipment of the carlson oil caps and I'm going to try 8,000 and see where that leads.

    Hi,
    Thank you for this great post!  
    I was diagnosed borderline diabetic, glucose intolerant/insulin resistant over 10 years ago. I figured out that a glucose meter could really help improve my health so I used it faithfully for many years. Now the strips are very expensive so I have cut back. But I learned an incredible amount while  using the glucometer.
    This is a fabulous method, and I highly recommend it.

    Heart effect of Doc's recommendation is very important if you are not young. Human ageing is accompanied by histological (molecular and cellular) changes in the vascular smooth muscle cells of the artery wall. It means that over time formation of atheroscleroma (plaque) becomes easier to develop - even if it has not done so, yet.

    Technically the molecules that are big players in the pro-inflammatory cycle are MCP-1 (monocyte chemo-attractant protein 1), MMP-2 (matrix metallo-proteinase type-II) and TGF-B1 (transforming growth factor beta-1). With age these are found circulating in elevated amounts; even in individuals without clinical problems. In other words genetic expression of them is upregulated, and it appears that age induces this epigenetic activation even if there is no diagnosable pathology.

    Now, Doc's clinical instruction is to hold down the small LDL production and reign in circulating triglycerides. This is because those are what will provide the fodder for the pro-inflammatory molecules' loop of interaction to actually go on to "make" actual plaque.

    Blood sugar spikes, according to Doc, are apparently the stalking horse for setting up our aged vascular system for pathological problems. We are accustomed to think of blood sugar as only a diabetics dilema; and so, many non-diabetics mistake Doc's insistance as not applicable to them.

    And, to those readers who have their own method of carbohydrate consumption it would be instructive to learn if any have tested, and might share, your small LDL percentage (mine is unsatisfactory to me, based on Doc's recommended %). This can add some perspective to see if this blog's "glucomania" is somewhat overblown.

    It's for Dr. Davis and not me to say what this blog is about, but my impression is that the goal is not just reversing but also preventing heart disease in the first place (and also the other ailments mentioned in the current post).

    Many of the people on the blog are healthy and want to stay that way, as opposed to being sick and wanting to be cured. I think I am in the first category myself, though I'm still awaiting the results of blood tests to know for sure. Already, I have made the following changes in my life due to reading this blog:

    1) taking 2000 IU/day of vitamin D3 in gel capsule.
    2) vitamin D blood test after a few months of the D3 supplement regime.
    3) using the glucose monitor to learn about my response to carbs.
    4) getting a VAP test to learn if I have Lp(a) and also get my VLDL numbers.
    5) Hb1Ac test.

    I am quite grateful for Dr Davis for pushing me to making these changes, but I think the anti-grain/anti-oatmeal focus is misguided.

    There is an epidemic of obsesity and type II diabetes in Pacific Islanders who eat junk food nowadays, but who were formerly lean on their traditional paleo low-carb diet of fish and coconuts. So why don't they go back to the fish and coconuts? BECAUSE CARBS ARE TASTY AND LOW-CA Neal is our record holder, but others are obtaining 10, 18, 24, 30% drops in scores all the time. Many have done it without l-arginine.

    Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score.

    My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time.

    There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden.

Track Your Plaque and non-commercialism

If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site.

We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent.

That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products.

Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info?

Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage.

I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation.

I'd welcome any feedback either through this Blog or through the contact@cureality.com.

The nattokinase scam

A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase.

The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification.

Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts.

Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase.

Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."

Don't you believe it. This is patent nonsense. There are several problems with this rationale:

--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right.

--Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them.

The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?

Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.

Blood pressure with exercise

Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.

Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range.

We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high.

Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)

I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel).

Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping.

Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary.

The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.

Vitamin D2 vs. vitamin D3

An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.

Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.

The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.

However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.

Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.

D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond tase">2/11/2011 3:21:39 AM |

I recently bought a ReliOn micro glucometer from Walmart after reading your recommendations, Dr. Davis. I'm 31, in excellent health, eat low-grain/starch most of the time, frequent anaerobic and aerobic exercise. My fasting glucose seems to rest in the 70-90 range.

Recently I decided to measure my glucose response after eating oatmeal. I used organic instant rolled oats and soaked them > 1 day in water with salt and lime juice, WAPF-style. I made a huge bowl of oatmeal (about 20 fluid ounces) and added blueberries and an appropriately huge amount of butter before eating. One hour later I measured my blood glucose using 2 separate test strips. I got 79 and 78. This surprised me, and I thought I'd add my data point to the discussion here.

No doubt a high fat load slowss gastric emptying and helps minimize the spike in blood glucose. Perhaps my reading would have been higher 2 hours after the meal.
