Lipoprotein testing

This is an update of a post I made about a year ago. However, I'm reposting it since the question comes up so often.


How can I get my lipoproteins tested?
This question came up on our recent online chat session and comes up frequently phone calls and e-mails.

If lipoprotein testing is the best way to uncover hidden causes of coronary heart disease, but your doctor is unable, unknowledgeable, or unwilling to help you, then what can you do?

There are several options:

1) Get the names of physicians who will obtain and interpret the test for you. That’s the best way. However, it is also the most difficult. Lipoprotein testing, despite over a decade of considerable scientific exploration and validation in thousands of research publications, still remains a sophisticated tool that only specialists in lipids will use. But this provides you with the best information on you’re your lipoproteins mean.
2) If you don’t have a doctor who can provide lipoprotein testing and interpretation, go to the websites for the three labs that actually perform the lipoprotein tests: www.liposcience.com (NMR); www.berkeleyheartlab.com (electropheresis or GGE); www.atherotech.com (ultracentrifugation). None of them will provide you with the names of actual physicians. They can provide you with the name of a local representative who will know (should know) which doctors in your area are well-acquainted with their technology. I prefer this route to just having a representative identify a laboratory in your area where the blood sample can be drawn, because you will still need a physician to interpret the results¾this is crucial. The test is of no use to you unless someone interprets it intelligently and understands the range of treatment possibilities available. Don’t be persuaded by your doctor if he/she agrees to have the blood drawn but has never seen the test before. This will be a waste of your time. That’s like hoping the kid next door can fix your car just because he says he fixed his Mom’s car once. Interpretation of lipoproteins takes time, education, and experience.

3) Seek out a lipidologist. Lipidologists are the new breed of physician who has sought out additional training and certification in lipid and lipoprotein disorders. Sometimes they’re listed in the yellow pages, or you can search online in your area. One drawback: Most lipidologists have been heavily brainwashed by the statin industry and tend to be heavy drug users.

4) Contact us. I frankly don’t like doing this because I feel that I can only provide limited information through this method and, frankly, it is very time consuming. I provide a written discussion of the implications and choices for treatment with the caveat to discuss them with your doctor, since I can’t provide medical advice without a formal medical relationship. We also charge $75 for the interpretation. But it’s better than nothing.

5) Make do with basic testing. Basic lipids along with a lipoprotein(a), C-reactive protein, fibrinogen, and homocysteine would provide a reasonable facsimile of lipoprotein testing. You’ll still lack small LDL and postprandial (after-eating) information, but you can still do reasonably well if you try to achieve the Track Your Plaque targets of 60-60-60. It’s sometimes a necessary compromise.

Our discussions on the Track Your Plaque Forum have impressed me with the difficulty many people encounter in getting lipoproteins drawn and interpreted. Some of our Members have been very resourceful identifying blood draw laboratories around the country, such as Lab Safe, that will at least provide the blood draw service.

I wish it was easier and we are working on some ideas to facilitate this nationwide. It will take time.

In 20 years, this will be a lot easier when doctors more commonly use lipoprotein testing. But for now, you can still obtain reasonably good results choosing one of the above alternatives.

Is it exercise or diet?

Wayne, a 61-year old retired school superintendent, had been an exercise fanatic all his adult life. If not running long distances and occasional marathons, he'd bike up to 70 miles a day. He did this year-round. In cold weather, he set his bicycle up on an indoor device and also ran on a treadmill and added weight training.

That's why it was kind of surprising that he sported a large belly. At 5 ft 8 inch and 190 lbs, that put his Body Mass Index (BMI) also high at 28.8 (desirable <25). You'd think that vigorous, almost extreme, exercise like this would guarantee a slender build.

Wayne also had lipoproteins to match: triglycerides 205 mg/dl, LDL 176 mg/dl but LDL particle number much higher at 2403 nmol/l (an effective LDL of 240 mg/dl); 75% of LDL particles were small.

I asked Wayne about his diet. "I eat healthy. Cheerios for breakfast usually. Some days I'll skip breakfast. Lunch is almost always a sandwich: tuna, turkey, something like that on whole wheat bread or a whole wheat bagel. Chips, too, but I guess that's not too healthy. Dinners vary and we eat pretty healthy. Almost never pizza or junk like that."

"Pasta?" I asked.

"Oh. sure. Two or three tiems a week. Always whole wheat. With a salad."

Wayne was well aware of the conventional advice for whole grains and, indeed, had been trying to increase his intake, particularly since his basic cholesterol numbers had been high in past. To his surprise, the more he tried at diet, the more LDL seemed to go up, as did triglycerides.

I see this situation every day: The obsession with processed carbohydrate foods, worsened by the message perpetuated by the American Heart Association, the USDA Food Pyramid, Kraft, Kelloggs, Post, etc. Eat more fiber, eat whole grains.

NY Times columnist, Jane Brody, chronicles her (embarassing) mis-adventure following the same mis-guided advice in Cutting Cholesterol, an Uphill Battle.

According to the USDA Food Pyramid, Wayne is not getting enough grains and whole grains, particularly since he is highly physically active. Consistent with the message given by the food industry: "Eat more!"

The food industry-supported Whole Grain Council advises:

Whole Grains at Every Meal
The US Dietary Guidelines recommend meeting the daily requirement by eating three "ounce-equivalents" of breads, rolls, cereals or other grain foods made with 100% whole grains. A slice of bread or a serving of breakfast cereal usually weighs about an ounce.

Want an easier way to think about it? Just look at your plate at each meal, and make sure you've included some source of whole grains. That's why our slogan is "Whole Grains at Every Meal."



By this scheme, if you are overweight, it's because you lack fiber and you're too inactive. "Get up and go!" It's not the diet, they say, it's you!

See through this for what it is: Nonsense. Wayne was overweight, packing 20 extra pounds in his abdomen from his over-dependence on processsed carbohydrates--"whole grains"--not from inactivity.

Instant heart disease reversal


What if reversal of heart disease--regression of coronary atherosclerotic plaque--were achievable instantly? Just add water and--voila!!

To my knowledge, it is not--yet. But I sometimes play with this idea in my head. I could imagine that such a program would consist of a few essential elements:

--A fast or semi-fast, or at least a very spare diet, over a period like 10 days to promote net catabolism. It is also supremely anti-inflammatory to restrict calories.

--High-dose vitamin D, e.g., 20,000 units per day of D3 to fully replenish depleted stores and achieve all the metabolism-correcting effects of D3 restoration.

--EPA + DHA at a higher than usual dose with frequent throughout-the-day dosing to encourage replacement of cellular lipid constituents with the more stable omega-3 fraction of fatty acids.

Beyond this, I'm uncertain. What role l-arginine, statins, niacin . . . conjugated linoleic acid? ApoA1 Milano infusions?

This is simply whimsical at this point. I don't know if such an approach would work. But if it did, you might imagine that it would offer an opportunity--for the properly motivated--as an alternative treatment for angina, advanced coronary disease, a means to pull someone back from the brink.

With the insights gained from our slow-but-powerful Track Your Plaque approach, perhaps we will also gain insights into how to accelerate such a process of reversal so that it is achievable in days, rather than months or years.

The small LDL epidemic

Ten years ago, small LDL was fairly common, affecting approximately 50% of the patients I'd see. For instance, an LDL particle number of 1800 nmol/l would be 40-50% small LDL in about half the people.

But in the last few years, I've witnessed an explosion in the proportion of people with small LDL, which now exceeds 80-90% of people. The people who show small LDL also show more severe patterns. 80-90% small LDL is not uncommon.

Why the surge in the small LDL pattern? Two reasons: 1) The extraordinary surge in excess weight and obesity, both of which favor formation of small LDL particles, and 2) over-reliance on processed carbohydrates, especially wheat-based convenience foods.

The constant media din that parrots such nonsense as the report on CNN Health website, Healthful Breakfast Tips to Keep You Fueled All Day, helps perpetuate this misguided advice. The dietitian they quote states:

"If you don't like what you're eating, you won't stick with it. If your choices aren't the most nutritious, small tweaks can make them more healthful. For example, if you have a sweet tooth in the morning, try a piece of nutty whole-grain bread spread with a tablespoon each of almond butter (it's slightly sweeter than peanut butter) and fruit preserves instead of eating foods that offer sweetness but little nutritional benefit, like doughnuts or muffins. If you enjoy egg dishes but don't have time to prepare your favorite before work, try microwaving an egg while toasting two slices whole wheat or rye (whole-grain) bread. Add a slice of low-fat cheese for a healthful breakfast sandwich that's ready in minutes. And don't overlook leftovers. If you feel like cold pizza (which contains antioxidant-filled tomato sauce, calcium-rich cheese, and lots of veggies), have it. It's a good breakfast that's better than no breakfast at all."

It sure sounds healthy, but it's same worn advice that has resulted in a nation drowning in obesity. The food choices advocated by this dietitian keep us fat. It also perpetuates this epidemic of small LDL particles.

If you have small LDL and its good friend, low HDL, it's time for elimination of wheat products, not some politically-correct silliness about increasing fiber by eating whole grains. Whole grains create small LDL! Or, I should say, what passes as whole grains on the supermarket shelves.

For some helpful commentary on this issue, see Fanatic Cook's latest post, Playing with Grains.

Mini-dose CTA?

I caught this little news report in the online edition of Canyon News , an LA paper, under the title Cedars-Sinai Develops Test to Prevent Heart Attacks .

They report that Dr. Daniel S. Berman M.D., chief of Cardiac Imaging and Nuclear Cardiology at Cedars-Sinai, reports that a new method of performing CT coronary angiography, "mini-dose CTA," has been developed that allows both coronary calcium scoring as well as CT coronary angiography (CTA) at a dose as low as 10% of standard dose. No technical details were provided.

Now, that may be worth knowing more about. If this is true, then CTA may indeed be useful as a "screening" procedure. However, we are going to need to know more: What devices are capable of doing this, what settings on the devices were used, etc. It does indeed come from a reputable source in Dr. Dan Berman, who is well known in nuclear cardiology circles.

We will try and dig for info. Stay tuned.

Wheat-free and weight loss

With a heart scan score of 1222, Leslie could be in deep trouble in short order.

At 64 years old, Leslie had gained nearly 40 lbs since she'd given up a lot of her activities caring for a husband who'd developed psychological difficulties and stopped contributing to the household duties. A tall woman at 5 ft 9 inches, she held her 202 lbs well, but her lipoprotein patterns were a disaster:

--LDL particle number 2482 nmol/l--an equivalent LDL cholesterol of 248 mg/dl (drop the last digit)
--HDL 38 mg/dl
--Triglycerides 241 mg/dl
--90% of LDL particles were small
--Lipoprotein(a) 240 nmol/l

Blood sugar was in the pre-diabetic range at 112 mg/dl, C-reactive protein was high at 3.0 mg/l, blood pressure was somewhat high at 140/84.

Now, with the exception of lipoprotein(a), these patterns are exquisitely weight-sensitive. A reduction in weight would yield effects superior to any medication I could give her.

Processed wheat products were a big problem for Leslie: whole wheat bread, pretzels for snacks, whole wheat pasta. Yes, they sound healthy, even endorsed by the American Heart Association, often bearing "heart healthy" labels on the packages. Don't you believe it.

In particular, Leslie had the number one cause for heart disease in America: small LDL particles, a pattern that is magnified 30-70% by wheat products. Endorsed by the Heart Association? (As I often tell people, if you want heart disease, follow the diet advocated by the American Heart Association.)

Leslie was skeptical, worried that she would be hungry all the time and would have virtually nothing left to eat. Instead, when she returned to the office three months later, she reported that eating was easy, finding healthy foods not containing wheat was easier than she thought, she felt great, finding more energy than she'd had in years.

She'd also shed 30 lbs.

Leslie's lipoprotein patterns also reflected the weight loss. She achieved her 60:60:60 Track Your Plaque lipid targets, small LDL shrunk dramatically, blood sugar and blood pressure were back in normal ranges.

I see results like Leslie's several times every week. For those of us with patterns like Leslie's, or just obesity that accumulates in the abdomen, going wheat-free is among the most powerful single strategies I know of.

If you need convincing, try an experiment. Eliminate--not reduce, but eliminate wheat products from your diet, whether or not the fancy label on the package says it's healthy, high in fiber, a "healthy low-fat snack", etc. This means no bread, pasta, crackers, cookies, breads, chips, pancakes, waffles, breading on chicken, rolls, bagels, cakes, breakfast cereal. I find elimination of wheat easier than just cutting back. I believe this is because wheat is powerfully addictive. It's very similar to telling an alcoholic that a drink now and then is okay--it just doesn't work. They need to be alcohol-free. Most of us need to be wheat-free, not just cut back.

You won't be hungry if you replace the lost calories with plenty of raw almonds, walnuts, pecans, sunflower and pumpkin seeds; more liberal use of healthy olive oil, canola oil and flaxseed oil; adding ground flaxseed and oat bran to yogurt, cottage cheese, etc.; and more lean proteins like lean beef, chicken, turkey, fish, and eggs.

The majority of people who go wheat-free lose weight, sometimes dramatically. Most people also feel better: more energy, more alert, better sleep, less mood swings. Time and again, people who try this will tell me that the daytime grogginess they've suffered and lived with for years, and would treat with loads of caffeine, is suddenly gone. They cruise through their day with extra energy.

Even without weight loss, going wheat-free usually raises HDL, reduces the dreaded small LDL dramtically. It also reduces triglycerides, blood sugar, C-reactive protein, blood pressure. Blood sugar control in diabetics is far easier, with less fluctuations and sharp rises in blood sugar.

Success at this also yields great advantage for your heart scan score control and reversal efforts.

Collective wisdom


As public consciousness and knowledge about health issues grows, thanks to the internet and other media, I predict that:

1) Hospitals will recede into a role of acute and catastrophic care ONLY, dropping the charade of providing health, which they do NOT.

2) Doctors and other health professionals will begin to see themselves as providers of acute and catastrophic care, also. They will stop providing day to day care, such as treating high blood pressure, cholesterol, breast exams, and other preventive maintenance.

3) Instead, preventive care will be self-provided. The public will have acquired sufficient savvy and know-how to manage issues like blood pressure themselves. They will need the assistance of helpful information resources, web-based for the most part. Much preventive care can, in fact, be algorithm-driven, just like following a simple recipe.

All the worries about runaway health care costs will be much reduced, since excessive testing driven by liability worries will disappear, repeated office visits for day-to-day issues will go away. Yes, you will need a doctor and hospital for a broken leg, car accident, unexpected cancer, or non-compliance or neglect of prevention.

But osteoporosis, high blood pressure, nutrition, weight loss, hormone management, cholesterol issues, minor complaints will all be managed by people themselves with the assistance of web-based knowledge systems.

I already sense this sort of phenomeonon developing, though in its infancy, in venues like the Track Your Plaque Forum and other health portals, places where the information being discussed exceeds the quality of information you can obtain from your doctor. Over and over again, for instance, the sophistication and knowledge demonstrated by our Track Your Plaque Forum discussions shows that the public is capable of far more understanding of health issues than many previously believed. Most of our members could carry on a credible conversation with trained lipid experts. The knowledge base of our members exceeds that of 98% of most of my colleagues when it comes to heart scans, lipoproteins, and nutrition.

I am in awe of Wikipedia, the popular online encyclopedia. Five 20- and 30-somethings have created a knowledge base that has now eclipsed Encyclopedia Britannica in size and scope, with equivalent accuracy, and relatively little cost. I'd like to see the same phenomenon occur in health care information, helping to usurp the current paternalistic "I'll tell you what to do" model.

Success--Slow but sure

John is a gentleman.

At age 76, he continues to teach at a local college. He's a delight to talk to, having written several scholarly books on religious topics. He's a fountain of knowledge on religious history and the roots of faith.

John is one of those incurably optimistic people, always greeting me with a smile and a warm handshake. I can't help but linger for a hour or so to talk with John, unfortunately disrupting my office schedule miserably.

John is another Track Your Plaque success story. Though he didn't set any records in reduction of his heart scan score, he did it simply by adhering to the program over a period of two years, succeeding slowly but surely.

John's first heart scan score: 1190, a score that carries as much as a 25% annual risk for heart attack. Among the list of causes was an LDL cholesterol in the 170 mg/dl range, along with an LDL particle number that verified the accuracy of LDL.

Among John's suggested treatments was a statin drug, since I was not confident he could reduce LDL with diet and nutritional modifications sufficiently to safely reduce both LDL and his risk for heart attack. But he proved terribly intolerant to any dose of any statin, with incapacitating and strange side-effects, like head-to-toe itching, abdominal cramps and diarrhea. It was clear: John needed to do the program without benefit of a statin drug.

I therefore asked John to maximize all efforts that reduce LDL, 70% of which were small LDL paricles despite his very slender build. He used oat bran and ground flaxseed daily, raw nuts, a soy protein smoothie every morning, and eliminated wheat and other high-glycemic index foods (including the Oreos he loved to snack on). Because the mis-adventures with statin drugs wasted nearly a year, I asked John to undergo another heart scan. Score 2: 1383, a 16% increase.

I asked John to keep on going. Thankfully, he did manage to tolerate fish oil, niacin (though it required over a year just to get to a 1000 mg per day dose), and vitamin D. With all these efforts, he did reduce LDL to the 80-90 mg/dl range. Of course, John's unflagging optimism was crucial. He did express his occasional anxiety over his heart scan score, but dealt with it in a logical, philosophical way. He understood that there was no role for prophylactic stents or bypass, and he accepted that much of his program rested on his ability to adhere to the strategies we advised.

Another year later, a 3rd heart scan: 1210, a 12% reduction.

I'm very proud of John and his success. When you think about it, he succeeded in conquering heart disease with some very simple tools, minus statin drugs. It can be done, but requires consistency and patience--and an optimistic outlook.

Vitamin D and octagenarians

Roger practically bounced in his chair vibrating with energy.

"It must be the vitamin D! I haven't felt like this in years. I can work around the yard all day and still have energy left over."

At age 84, Roger started out with pretty good health, despite a prosthetic valve and bypass surgery 5 years earlier. He looked 74, perhaps younger.

I've seen this effect now in about 20 octagenarians. A Track Your Plaque Member mentioned this same effect in his father-in-law in a discussion in our Forum. Most are taking around 6000-8000 units per day (gelcap, of course). The average dose of vitamin D tends to be higher in this age group, since by age 80, you've essentially lost the capacity to convert 7-hydrocholesterol to active vitamin D3 in the skin. Most octagenarians start with 25-OH-vitamin D3 levels of 10 ng/ml or less--profound deficiency.

I believe the effect is real, having now witnessed it multiple times. Unfortunately, my observations are too informal to qualify as a study. (I wouldn't even know how to quantify this. I suppose some sort of muscle and coordination testing might yield quantifiable measures.) However, there are some data emerging that show less fractures, falls, improved coordination, and perhaps improved memory and mentation with vitamin D supplementation, though doses often used in studies tend to be lower than what we are using in practice.

I haven't been so excited about the effects of a nutritional supplement in a long time. Vitamin D continues to yield surprises every day in its array of positive and powerful effects.

Could we say that vitamin D restores youthfulness?
Construct your glucose curve

Construct your glucose curve

In a previous Heart Scan Blog post, I discussed how to make use of postprandial (after-meal) blood sugars to reduce triglycerides, reduce small LDL, increase HDL, reduce blood pressure and inflammatory measures, and accelerate weight loss.

In that post, I suggested checking blood glucose one hour after finishing a meal. However, this is a bit of an oversimplification. Let me explain.

A number of factors influence the magnitude of blood glucose rise after a meal:

--Quantity of carbohydrates
--Digestibility of carbohydrates--The amylopectin A of wheat, for example, is among the most digestible of all, increasing blood sugar higher and faster.
--Fat and protein, both of which blunt the glucose rise (though only modestly).
--Inclusion of foods that slow gastric emptying, such as vinegar and fibers.
--Body weight, age, recent exercise

Just to name a few. Even if 10 people are fed identical meals, each person will have a somewhat different blood glucose pattern.

So it can be helpful to not just assume that 60 minutes will be your peak, but to establish your individual peak. It will vary from meal-to-meal, day-to-day, but you can get a pretty good sense of blood glucose behavior by constructing your own postprandial glucose curve.

Say I have a breakfast of oatmeal: slow-cooked, stoneground oatmeal with skim milk, a few walnuts, blueberries. Blood glucose prior: 95 mg/dl. Blood glucose one-hour postprandial: 160 mg/dl.

Rather than taking a one-hour blood glucose, let's instead take it every 15 minutes after you finish eating your oatmeal:


In this instance, the glucose peak occurred at 90-minutes after eating. 90-minute postprandial checks may therefore better reflect postprandial glucose peaks for this theoretical individual.

I previously picked 60-minutes postprandial to approximate the peak. You have the option of going a step better by, at least one time, performing your own every-15-minute glucose check to establish your own curve.

    There is evidence that alcohol decreases the blood glucose rise, which may explain in part why moderate drinkers have lower risk of heart attacks. Have you found this to be true?

    With all respects, Doctor Davis, but I am at a loss to understand your reasoning behind the suggestion of constructing a 2-hour curve with readings taken every 15 minutes. Invariably after eating, blood glucose level will rise and then fall over the two-hour period. I can control the severity of the "spike" by the type of food I consume. After eating however, I cannot control the shape of the curve without the intervention of medication or physical exercise. This is known. So what additional practical information is provided me from this exercise?

    Hi, Kurt--

    The effects of alcohol and alcoholic beverages are complex. The blood sugar effect is only a small part of the equation. Among the most consistent effects are reduced blood sugar with red wine, increased blood sugar with beer.

    I almost had a wheat relapse today, but what I realized is that I wanted the butter. So, I ate a small bite of organic butter.

    Carbohydrates don't screw up health in most people, but they have to be managed properly. Anonymous's glucose spike occurred because he/she surprised the body with a heavier carb load than it was adapted to. It takes a week or so for the body to upregulate insulin sensitivity and glycogen storage ability. Until that upregulation occurs, high carb intake will indeed cause glucose spikes.

    Here's my own anecdote. After switching to a paleo diet for a week, I then switched back to high-carb. Upon eating 200g (dry) of cooked oats, my glucose shot up to 195 mg/dL. A week later, I was able to eat the same 200g (dry) of cooked oats and glucose remained below 120 mg/dL. What happened is that my ability to process glucose downregulated when I switched to paleo, then upregulated after I switched back to high-carb. Both the down and upregulation take a few days. It is probably inadvisable to constantly switch between paleo and high-carb. If you plan to eat high-carb, then do so consistently, so that the body is always prepared for high glucose loads.

    My recent VAP blood tests, taken after resuming my usual high-carb regimen, show HDL=66 mg/dL, LDL=61, VLDL=12, Trig=45, Lp(a)=15, HDL-2=23 (most protective HDL greater than Lp(a), thus counteracting the latter), and type A LDL pattern (mostly large buoyant LDL). CRP was .16mg/L, which is very low. Laboratory measurement of fasting glucose was 85 mg/dL, versus 84 for Reli-On Confirm home glucose testing device measured that same morning (the Reli-On device thus appears to be accurate). These results hardly suggest that a high-carb diet necessarily screws up health.

    There is also plenty of other evidence that carbs are not unhealthy for people who are lean, get daily exercise, don't have an underlying illness, and eat mostly unrefined carbs. All sorts of primitive peoples (Kitavans, Tarahumara indians, Bantus,  traditional mediterranean people's, etc) eat high-carb diets and have very low incidence of diabetes, heart disease and other chronic illnesses due to diet (they may have chronic illnesses due to parasites).

    Depression a variable: Japan 2010 journal "Anti- Aging" showed affect on blood glucose in 5 hour glucose(75 grams) tolerance test on a clinic's depressed in-patient (woman age 36). The articles authors conclude a "very low saccharide diet" is better for the brain, which runs fine on ketones.

    Fasting blood sugar = 74
    30 min post glucose = 97
    1  hour  "    "     = 78
       (coincides with insulin peak)
    2 hour post glucose = 54
       (27% below fasting blood    
        sugar)
    3 hour post glucose = 99
       (insulin less than 1/2 of
        30 min. insulin & 1/3 of
         2 hour insulin)
    4 hour post glucose = 75
    5 hour "     "       = 80

    I have a big question here.
    I persoanlly have my peak at 30 minutes. So my question is:
    Is it a BG of 140-160 after 30 minutes if after 60 minutes it is under 100 too bad?

    @Might-o'chondri-AL: Can't understand the logic of low-carb for depressed people. High-carb boosts serotonin. The only reason I could think of prescribing low-carb for a depressed person is because they are overweight, and the excess weight is partly responsible for the depression (inability to move about and exercise due to morbid obesity, for example).

    revelo, thanks for some sanity.  Reading these blog posts and most of the comments that follow is depressing.  They would have everyone believe that their inability to handle carbs is representative of normal, healthy, individuals.

    Maybe they need to get healthy, and then they can actually eat whole-food sources of carbs and stop being so scared and go and live life.

    Hi Revelo,
    I've got nothing against carbs & am still learning (I eat carbs); your blood profile seems excellent enough to trade for.My thinking on your approach is: that you may find, like me in my 20/30/40s + years, care free
    carbohydrates are fine and by
    the time hit 60 there's the unforseen to adjust to. The famous quote is: "Old age ain't for sissys."
      
    So, back to Japan ....
    Psychiatric clinic tested 2,000;
    detailed one to show how variable blood sugar/insulin expression is in depression. They claim to have got her off meds and adressed low neuro-transmitters of depression; which clinically they say (depression) is common in metabolic syndrome.

    Their flow chart for seratonin is dietary amino acid L-tryptophan as substrate with folic acid, iron, niacin and enzyme tryptophan hydroxylase; yields, 5-HTP with vitamin B6 and enzyme 5-HTP decarboxylase; yields seratonin (which in it's own right is the substrate for
    magnesium and SAMe to make into melatonin). I'll skip their GABA and dopamine flow charts.

    This was a geriatric symposium paper, so focus was on brain down the line. Their pitch was for preventing cognitive decline;
    and that ketones protect the brain from Alzheimers and Parkinsons - just as ketones diets do help in
    epilesy and other mental disorders.

    They specify that in the brain beta-hydroxy-butyrate (ketone) ups utilization of circulating oxygen more, decreases CO2 in tissues from glucose "burning", and ketones make ATP more efficiently too. As for the mitochondria, they continue to get their essential glucose molecules from gluco-neogenesis.

    My impression is they're showing that in geriatrics the potential
    accumulation of what Doc's blog
    warned about, namely  A.G.E.s
    (advanced glycation endproducts)is a risk factor for Alzheimers, etc. The authors conclusion was the central nervous system used ketones just fine;and carbohydrates were not required for old people to have good levels of circulating blood sugar.

    Dr Davis: Two comments were made asking for your reasoning behind the suggestion for construction of a 2 hr curve. To me the comments are politely made. They are appropriate in my opinion and they deserve a response. It is obvious that you chose deliberately to ignore them.

    Your commentary is followed and I expect influences countless readers; some possibly obsessively, ie healthy individual who performed more the 75 glucose checks over a few days time.

    With your efforts to maintain this blog come added responsibilities to its readers which you currently are ignoring.

    Shame on you.

    Anonymous: Your response to this blog is somewhat emotional and critical. Perhaps you could be open to the idea that some people can consume a high, unrefined carbo diet and be healthy; others will suffer adverse effects on a high carbo diet and need a more protein based or mixed diet. For those individuals that are carbo sensitive, there is good dietary advise on the blog. I do not currently test my blood sugar. I do not want to become myopic about health; however,I don't judge others on this blog who want to pursue this strategy even if they are not insulin resistant, diabetic or pre-diabetic. Moreover, I may have to resort to using a monitor in the future. The blood sugar data from another "anonymous" is very interesting and certainly provides real data for determining his or her dietary choices. Please keep an open mind and avoid insulting comments like "shame on you" which add nothing to the dicussion and are meant to insult not to educate or enlighten others.

    DexCom 7 is a "continuous" bg monitor for home use. http://www.dexcom.com/products

    I have been eating Dr Fuhrman's diet and lately, typical meal contains 3-4 cups chopped leafy greens, 2/3 cups cooked beans, about 2/3 oz raw seeds/nuts, 200 grams starchy root veg, one piece of fruit (most often an apple).  Peak postprandial sugars for me come very close to one hour after end of meal and are in low 120's to high hundred teens, back to fasting by 90-120 minutes Usually 90 minutes).

    why do you think that post meal levels of 120 or 140 are "normal"? Simply because are the levels that people get when eat a lot of carbs in a meal.

    You body do not like this levels, that is why it try to put them down using insulin. Why is your body doing that if they are "normal levels"?

    If you check my levels in the 4 reply you could find that when you do not eat for longs periods of time your body try keep your sugar between 70 and 90. If you are relaxed the level could be in the 70 zone and if you do some exercise it will go to 90 zone. Why your body do no increase it to "normal levels" of 120-140? Probably because this levels are not "normal".

    So you have a high carb meal. Your body react to it trying to keep your sugar down, why?. Yes... your body is stupid and doesn't have a degree in nutrition so cannot understand the science behind this "normal levels".

    When you body finally got the 85 level your dietitian says that you need to have another high carb meal. So your levels return to 120-140, and you ignorant body starts to reduce this "normal level" to 70-85. When you got that level is time to have another high carb meal, and your ignorant body returns to do the same trick.

    Years of doing that and your body cannot maintain the true normal levels your doctor says that you need to do some exercise to well... reduce sugar levels! and of course still doing 5-6 small high carb meals a day.

    So now you need to run the New York City Marathon to get rid of all that carbs in all that meals your are eating during the day.

    Of course you need increase the carbs in these meals to have energy to do all that exercises. In one of those healthy marathons you also take a high carb drink to... well... you know.

    It doesn't work, you end eating more than before because your body needs more energy to run all that healthy marathons and you are all the day hungry.

    Later your unscientific and stupid  pancreas collapse and your doctor says that you need to maintain your 34646464 high carbs meals a day, but take some insulin to help your body to reduce all the sugars YOU ARE EATING EVERY 3 HOURS.

    Probably our pancreas simply commit suicide because is not able to understand our rock solid science.

    A couple of people have asked why construct your own glucose curve so I thought I'd throw out my thoughts on it.  Every person's glucose will peak at different points either due to slower stomach emptying or a slower absorbed carb or whatever. I have read that many people will peak at 75 minutes.  So if you are trying to get a real idea as to how your body reacts to glucose/insulin then you need to test frequently to find YOUR personal peak.  Then you will know when to test when you try new foods.  Is that others understanding too?

    This blog post is so full of Fear, Uncertainty, and Doubt.  People asking questions due to being scared by Dr. Davis' suggestion of "constructing your glucose curve", so they ask him questions in the comments, like what their "glucose curve" should look like.  People thinking now they better be jabbing themselves 15 times after a meal.  Thinking about a meal for hours after a meal.  Guilt for eating that meal.

    So Dr. Davis' response?  IGNORE THEM and put up a new blog post with MORE scare-mongering:


    Now you should fear the banana!
    http://www.heartscanblog.org/2011/02/american-heart-association-diet-makes.html

    "Would you like a banana?"


    What a joke.  Show us a single person who got fat off of bananas OR potatoes, or any whole food carbs.

    Hi Peter,
    Up-regulate is an action on a gene that makes it do more of what it's capable of doing. And down-regulate is when a gene is being acted on in a way that it will do less of what it's capable of doing.

    A gene can be overactive or underactive. Depending on the dynamic, of how a specific gene ideally should be doing, regulation up or down is desired.

    Hey there Dr Davis,

    Created my own glucose curve as part of my own research and actually got a bit of a scare!

    I was doing a high carb meal to try and demonstrate an early carb spike then drop.

    While I didn't get the response I was looking for I got something a bit scarier. A fasting glucose indicitive of pre-diabetes reading instead. I am amazed how one bad meal was able to send my sugar awol over night.

    Back onto low carbs for me.

    Thanks for helping open my eyes to my potential diabetes.

    Dr George
