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?
Atkins Diet: Common errors

Atkins Diet: Common errors

No doubt: The diet approach advocated by the late Dr. Robert Atkins was a heck of a lot closer to an ideal diet than the knuckleheaded advice emitting from the USDA, American Heart Association, American Diabetes Association, and the Surgeon General's office.

But having just spent a week with Atkins low-carbers, here are some common errors that I see many make, errors that I believe have long-term health consequences, including impairment of weight loss.

Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods.

Consumption of cured meats--Cured, processed meats, such as sausage, hot dogs, salami, bologna, and bacon, have a color fixative called sodium nitrite, an additive that has been confidently linked to gastrointestinal cancers. Risk is likely dose-dependent: The more you ingest, the greater the long-term risk.

Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

Too many calories--While I agree that "a calorie is a calorie" and "calories in, calories out" are faulty concepts, I have anecdotally observed that long-time low-carbers often trend towards unlimited consumption of food, a phenomenon that seems to result in weight gain, especially in the sedentary. I wonder if this is a reflection of the insulinotropic action of dairy products and other proteins, compounded by the poor insulin responsiveness that develops with lack of physical activity. Factor into this conversation that lower calorie intake extends life, probably substantially (Sirt-2 activation and related phenomena, a la resveratrol). If lower calorie intake extends life, unlimited calorie intake likely shortens life.

Please don't hear this as low-carb bashing--it is not. It is a call to improve diets and not stumble into common traps that can impair heart health, weight loss, and longevity.

    Please could you provide links to the interventional controlled (not observational) studies that have shown a link between eating meat and cancer risk, that separate the effect from eating junk food, and the fact that vegetarians are more likely to eat healthily in general than meat eaters due to the widespread and incorrect belief that saturated fat is harmful to health.

    Also, could you explain lack of cancer in traditional tribal societies with a high meat intake? You would need to do this before stating that meat intake necessarily increases cancer risk.

    Hi doc,

    Great blog. How do you explain the Inuit, Masaai, Komi (Siberia), Native American and similar cultural groups whose diets seemed to subsist primarily on animal products? ie. including my ancestors.

    Perhaps its an emphasis on wild/grass-fed/raw dairy(or as close to) animal products as opposed to the grain-fed animal products which encompass the majority of the US that you need to be addressing?

    Thanks.

    Great diet, and yes, it seems that we should talk about healthy eating instead of weight loss or diets. Anyway the purpose of any diet is to move your eating habits to new healthy level.

    Thanks for sharing and possibility to comment! Welcome to visit Ideal Weight Blog to find some recipes and great articles! Thanks!

    Just on the nitrate/nitrite subject: as far as I know nitrate is a naturally occurring compound and the human exposure to it is mostly through  consumption of vegetables, and to a lesser extent water and other foods...

    I would say there are 3 primary pitfalls of low-carb dieting:

    1) Being too low in carbohydrates - being in ketosis is anti-metabolic and induces insulin resistance, and probably why Atkins suggested that his diet "tends to shut down the thyroid."  

    2) Too much protein - this strains the thyroid as well, and encourages gluconeogenesis, which is also problematic - especially when in ketosis and insulin resistance is extreme.  

    3) Extremely high in omega 6 polyunsaturated fat.  Eating a low carb diet with lots of pork fat, chicken skin, peanut butter, and nuts - the typical standbys of many low-carb dieters, provides an astronomical amount of omega 6.

    By my best guesses, I was consuming 15+ grams of omega 6 while on a low-carb diet.  I've since cut that back to less than 3 grams per day and the change has been dramatic.  Of course the 400 grams of carbs per day helps too.

    Dr. Davis,
    Thank you for this post.  I'm certainly culpable of the "common errors" you mention.  I find that making daily decisions on what to eat difficult. I want to eat healthy and have some variety. Here's the question.  What do you eat?  What did you have for breakfast this morning?  What did you eat last night?  What do you keep in the fridge and on the counter to make following your dictates easier.
    I don't want to over-think it but all this information is overwhelming.  I feel like a scientist and my body is the research subject.
    Thank you for your blog.  I've learned a lot but need some direct guidance.
    Sincerely,
    Dana Law

  • Tim

    Have you really read the meat leading to cancer literature carefully or do you just think it's like that? Others like Gary Taubes and Eades (who I really trust when it comes to research) have found no evidence that meat cause cancer.

    On sodium nitrate, I totally agree. I get so mad when I'm walking in the grocery stores. All meat has sodium nitrate added. Grrr.

    I share your thought about dairy. But do you really mean that butter triggers insulin spikes?

  • Daniel

    Most nitrite is form your own spit and originally ingested by eating vegetables.  

    I believe the epidemiological studies (which also typically find fat to have bad associations...) have more to do with a lack of fruits/vegetables/polyphenols than anything that is bad about meat.  

    Also, I don't think glycemic index or the insulinotropic nature of certain proteins matters one lick for people that are healthy.  I can eat a boiled potato for breakfast without my blood sugar breaking 100... I don't think diabetes is an overuse injury - more likely, it is cause by damage to the liver and then pancreas from PUFA and fructose overconsumption.  

    I think Matt Stone is correct about the top three problems with Atkins.

    If you're really concerned about your nitrite intake, watch your celery, arugula and spinach (and many other vegetables) consumption, too. Nitrites galore. Though it's not nitrites and nitrates in and of themselves that are linked to cancer, it's the nitrosamines that can form from them.

    Sodium nitrite isn't primarily a colour fixative, it's a an anti-bacterial agent. Meats cured with sodium chloride only have to be done quite carefully to avoid botulism. Nitrite has been used since the 16th century to preserve meat. Modern cured meats also add sodium ascorbate, and ascorbates have been shown to inhibit nitrosation reactions and thus the nitroamine level in these cured meats is usually at undetecable levels.

    Nitrites are produced in our mouths from bacterial reactions to the nitrates in food and water, and at least 70% of our dietary nitrite comes from this salivary nitrite (which came from our food and water). The nitrites and nitrates we then ingest are mostly either excreted fairly promptly or used to make nitric oxide. Human gastric secretions have a pH which isn't condusive to nitrosamine formation, and also include ascorbates which reduce nitrosamine formation, and keeping one's vitamin C at good levels will also have an effect. People with achlorhydria will obviously be more susceptible to nitrosamine formation. But interestingly, there are studies which now suggest that nitrite consumption is a good thing: http://www.ncbi.nlm.nih.gov/pubmed/20005970 - and branched-chain amino acids are also suggested as suppressing the effect of nitrosamines. However the amount of nitrosamines you get from smoking is definitely Not Good, and no amount of ascorbate will ameliorate it.

    So, a good intake of nitrates and nitrites primarily through vegetables, some fruit, and some cured meat is good: the vegetables and fruit contain ascorbates as does your body, and most of hte meat should have it added also, minimising the formation of nitrosamines, leaving your body to get on with making use of the nitr*tes to make needed nitric oxide. (Oral nitric oxide/arginine supplements are rubbish though - the studies showing their benefit used intravenous/injected supplement.)

    Personally, I'll take nitrites over botulism, thanks.

    Hmmm, I've never been on a cruise, but if I did go on one, I'll bet I'd have to eat somewhat differently than I do at home, regardless of the carb count.  Between not having access to the pastured bison and wild game, raw dairy, "backyard" eggs, and organic CSA produce subscription, and so on that make up most of my family's daily diet, and no access to a kitchen, my meals on a cruise would hardly be representative of my usual diet.  

    I'll bet LC cruisers are as prone to anyone when it comes to the excesses of endless supply of prepared foods on cruises, but I'm not sure we can assume that's the way they always eat.  Most people  eat somewhat differently on vacation, whether it's because they are on somewhat of a "diet vacation", or because they have to make the best of what's available.  When I was on vacation in Italy I had a gelato every day, but I certainly don't do that at home (it was a conscious decision to take a slight vacation from my diet and enjoy a local specialty for a limited time).  And I've been places where it was impossible to get eggs cooked in real butter instead of the ubiquitous "griddle grease" hydrogenated veggie oil, let alone pastured eggs and humanely produced bacon (seriously, we breakfasted at a tiny roadside diner outside Twenty-Nine Palms that had NO butter on the premises).  

    And not all LC eaters are following an Atkin's diet plan, though I understand the Atkins label has become be a generic term for LC eating.  I've read an Atkins book (as well as at least a half dozen other LC diet books).  I eat LC (& GF now) but I've never followed specifically an Atkin's diet plan, nor do I describe myself as at Atkin's dieter.

    I think the points you make point out that even on low carb, people can and do still rely on far too much industrial food.  It's convenient and it's everywhere (hard to avoid, esp when dining away from home).  Frankly, one of the reasons cruise vacations hold little appeal to me is the idea of having to nothing to eat all week but cr@p industrial food, no matter how talented the chefs may be at making it look and taste good.   I may be making a sweeping assumption, but somehow I don't imagine that cruise chefs are simmering their own bone broth stocks, curing charcuterie themselves, and making their own cheese (or even sourcing from small artisan vendors  very much).    I'd be extremely surprised if cruise ship food ingredients weren't offloaded from US Food tractor trailer trucks.  That's what I've seen at many land-based resorts.  When I travel,  as much as possible, I want to try the local traditional foods and specialties, prepared as authentically as possible.  That might mean eating more of something than usual (and less, too).

    Isn't it also an Atkins diet error that low-carb eaters tend to be on a constant and frantic quest for processed fake food items that are pretend substitutes for the food that got them in trouble in the first place?  And many of them have made Jimmy Moore, a huge hawker of low-carb substitutes and a less-than-successful low-carber, their role model.  

    I noticed on Swedish physician Dr. Andreas Eenfeldt's blog that his description of his experience on the cruise was that "[t]he big difference with Sweden is that many are fond of low-carb versions of traditional junk food, sugar, and so. Low carb cake, low carb icecream, low carb potato chips, diet sodas ... In my eyes seemed to just those participants who ate such did not have the same persuasive power of the diet. To put it nicely. Perhaps it was the roundest of them all, the man [Andrew DiMino -- Carbsmart.com?] who handed out the various "low carb" products that are advertising for his company. [Google translation]

    People I know who have been totally unsuccessful on Atkins have gleefully loaded up on "substitutes" that probably have derailed them.  And the Atkins company that sells this crap will forever keep the Atkins mantra from the gaining the credibility it probably deserves.

    Bill you said:

    "Excessive consumption of animal products--Non-restriction of fat often leads to over-reliance on animal products. Higher intakes of red meats (heme proteins?) have been strongly associated with increased risk for colon and other gastrointestinal tract cancers. It is not a fat issue; it is an animal product issue. We should consume less meat, more vegetables and other plant-sourced foods."

    I don't think this is true Bill. As far as I'm aware, there is no good evidence to support protein as cancer causing. Dr. Eades has debunked this on his blog.

    Ditto what Tim said. My understanding is that it's the whey in dairy that is insulinogenic (tho it's a bit like the glycemic index ... it depends on when and what you eat it with).

    Butter should not be as big a problem. One of my go-tos is ghee from grass-fed cows. The small amount of milk solids left in butter are removed when ghee is made.

    If you cut out animal protein, dairy, and carbs, there's not much left to eat.

    The protein sources favored by vegetarians, beans, rice, and grains, make blood sugar increase too much for people with diabetes.

    One can not live on tofu and fat alone, and anyway some people say too much soy is not good.

    I don't know why people have a prejudice against dairy. See this:

    http://care.diabetesjournals.org/content/29/7/1579.full

    If you have a diabetic tendency, it means your beta cells aren't producing enough insulin, so a food that helps them along is good.

    Too many calories on a high fat diet? Good luck keeping that up. I can't get 2000 most days. Too full.

    Why were there traditional societies that used dairy as a staple yet were free of CVD and diabetes, including the super long lived people on the border of Eastern Europe and Central Asia?

    Copy and paste the above argument for "eating too much meat."

    Low carb may not be for everyone, but the biggest problem with some low carbers is probably too much n-6 from processed meat. Lots of nuts aren't that good for you either.

It is not all about meqat meat meat or even high protein. And as much as I enjoy your blog- you still have a huge fear of fat. With Atkins I have improved my metabolic problems.

  • Helen

    3/18/2010 7:12:05 PM |

    I've been concerned to learn, here and elsewhere, that dairy products are insulinogenic, particularly since I can't seem to manage a reasonable diet without a fair amount of them.  (Nuts don't do well with me, soy is a no-go, I can only eat so much meat, my family has egg-allergy issues, and the fish that is non-contaminated, sustainably caught, not-BPA-canned, not-fed omega-6 and dioxin-laced stuff in a disgusting fish farm, is wicked expensive and logistically impossible to get fresh for my family more than once a week....)

    On the other hand, there are several dairy-reliant cultures that are quite long-lived and healthy, and dairy-consuming people in our own culture tend to be healthier than non-dairy eaters.  So maybe something mitigates the insulin question with dairy.  Just saying.

    In the end, you have to eat something, and sometimes reading this blog I feel I can't eat anything.  Like Dana Law, I'd like a better picture of what an ideal, or at least acceptable, day's or week's diet would look like from your point of view.

    I've followed Atkins for these last three years, losing 80lbs in the process, so am quite familiar with what's permitted and not.

    Atkins did not recommend consuming any milk, nor was much yogurt or cottage cheese permitted. Hard cheese, cream cheese and heavy cream are allowed, but the Atkins diet permits less than 2-3 oz per day.

    Butter is allowed liberally, but is 100% fat so can't be very insunlinotropic, if at all.

    Because I raise dairy goats, until three years ago, I drank goat milk freel.  Now I never drink it, though I do have a glass of very sour kefir now and then, after the probiotics have cultured most of the lactose into lactic acid.  The kefir I drink is very tart. Most people don't like it that sour. lol

    The "Atkins is High-Protein" myth is often bandied about by anti-low-carb groups. I track my daily intake on FitDay and it's usually about 15-18% protein, 65-70% fat, and 10-20% carbs... pretty much what Atkins recommended; even 20% protein is not especially high protein.

    My carbs come mostly from eggs, green vegetables, heavy cream for coffee, berries and other LC fruit, and certain nuts and seeds, like flax.  Peanut butter is very carby, and not freely allowed in Atkins.

    I recommend reading the old Atkins book to understand what his diet really contains. Read the 1972 version, as the newer books (after 1999) were changed by Atkins Nutritionals to allow low-carb junk food that they conveniently sell.

    I think that you should eat meat. I am a former vegetarian and I don't particularly like meat. Despite this, I do feel that humans are meant to be carnivorous. I just don't believe that piling your plate high with animal products several times per day is the ideal way to eat.

  • Haggus

    3/18/2010 9:58:20 PM |

    Dr. Davis, you sure it was "Atkins low-carbers" you were with?

    "Excessive consumption of animal products"

    At least with DANDR 2002, as you go up higher on the rungs, meat is replaced somewhat by veggies.  Personally, I eat around 200g of meat per day.  Of that, less than 90g is red meat (the rest is fish.)

    "Consumption of cured meat"

    I love bacon as much as the next guy, but in even Dr. Atkins stated in DANDR 20002 that one should "try to avoid meat and fish products cured with nitrates, which are known carcinogens."

    As for dairy, it's not taboo but still has to be fitted into the carbs you are allowed per day.

    This is the second blog post since the trip you have me scratching my head.  I hit your 60-60-60 markers using oat bran all the while being IGT and sporting an A1c of 4.8%.  (And before anyone asks, in DANDR 2002 Dr. Atkins mentions oat bran to bring down your cholesterol levels.)

    Try to do that for an extended period of time. I lasted about 2 weeks. Now I have a very small meaty breakfast, and a modest size meaty dinner, and I'm STUFFED. Been like this for years. Can't eat lunch-not hungry.

    You prefer plant foods which is great, but you're not in a carnivore's shoes. From our perspective, what you say is rather silly because many of us actually worry about not getting enough calories! Fat is filling. I'm a 6ft, 165 lb male and I can barely get 2000 calories I feel so full.

    Here's a good take on the conventional "wisdom" of nitrates: http://junkfoodscience.blogspot.com/2008/07/does-banning-hotdogs-and-bacon-make.html

    Matt:

    "Being too low in carbohydrates - being in ketosis is anti-metabolic and induces insulin resistance, and probably why Atkins suggested that his diet 'tends to shut down the thyroid.'"

    I generally find your thoughts to be spot-on, so there's no need to manipulate Atkins' quote to enhance your point.  What he said was that dieting in general tends to shut down the thyroid.

    "[P]rolonged dieting [including ‘this one’] tends to shut down thyroid function."

  • sonagi92

    3/18/2010 11:25:42 PM |

    I knew that dairy was insulinotropic, but like Emily, I was surprised to see butter on the list as butter is mostly fat, and clarified butter entirely fat.  As I understand, it is protein-rich foods like beef, chicken, and fish, that provoke unexpectedly high insulin responses, so I thought it was either the sugars or the protein in dairy, not the fat, that spiked a rise in blood sugar.  Is butter really insulinotropic like other dairy products containing lactose sugars and proteins?

  • sonagi92

    3/18/2010 11:39:43 PM |

    Another comment about dairy and weight gain:

    I have noticed that melted cheese in particular - a warm, creamy fat with some carbs and protein - is highly palatable.  Full-fat yogurt, whipped cream, and guacamole are similarly irresistible.  I could not consume more than a couple tablespoons of olive oil yet have no trouble gobbling down a few slices of cheese melted onto a piece of chicken or beef.  I'm trying to shave off 5 more pounds to reach my goal, so I've given up all dairy except for clarified butter, which I use to saute veggies.  Will see if this works.

Should slimness be a goal every low-carber can meet (apart from all the other health benefits)?

    How high is "too high?" I say this not to be a smart aleck or to overlook the wisdom in "you'll know it when you see it," but this is a bit too vague to be of much use.

    Clearly a largely plant-based diet supplemented with a decent amount of animal protein will trump loading up heavily on animal products to the exclusion of plant-based foods. But there's far too many vague generalizations being bandied about by so-called dietary experts these days and not a lot of concrete recommendations that can be tailored to fit a person's unique context.

    I would also like to see a typical day in the life of Dr. Davis.

    Anon-  Yes, they mean a % of total calories.  You can figure it this way:

    1g Protein = 4 cals
    1g Carb = 4 cals
    1g Fat = 9 cals

    So if a person eats 2000 cals/day and 18% was from protein, then that person ate approximately 360 cals of protein.  Divide 360 by 4 and you get 90 grams of protein.

    I agree that there are many low carbers who follow their eating plan less than optimally. I see them posting on the low carb forums I follow. But as one who was also on the cruise, I don't think you can really equate cruise eating with what people eat on a normal day-to-day basis!

    I had resolved to eat only "real food" on the cruise, as I almost always do at home, and I had resolved not to snack. And I was pretty good about my resolve. I didn't snack, ate only three meals a day, avoided the flour, sugar, even the sugar-free cheesecake and other things provided.

    But did I eat exactly the way I would eat at home? No, I didn't. I undoubtedly ate more than I would have eaten at home, and probably certainly more protein sources than I would have eaten at home. The last night of the cruise I even broke down and had one of the sugar-free margaritas, and I had a half glass of red wine at the comedy show.

    And I'm sure my PUFA intake was higher than I would normally like. We had no control over how foods were prepared in the kitchen after all, or very little.

    But this was 5 days out of my life, not a lifetime of eating. Smile I didn't gain any weight on the cruise and indeed have even hit a new low this week since being back. Overall I've lost more than 100 pounds.  

    I'm not convinced of the meat/cancer link either - though too much protein raises my blood sugar so I don't normal OD on protein much. I was never a vegetarian but often thought I could have gone that way as I'm not all that crazy about meat. But now I have an "It's them or me" attitude and look for meats I  enjoy better - just not too much.

    Apparently Matt Stone has challenged my son to try out a super-low-calorie, essentially fat-free diet, based on 1930s research by Evans and Strang, and I'm following his progress with interest. But at the moment it's not for me. I still love my butter and coconut oil.

    But we are all so different, and what works for one may not work well for another. But I wonder how many low carbers eat at home the same way they ate on the cruise?

    Anon said: "Whenever I read this sort of thing, I get confused. 15-18% of WHAT? the total calories? and if so then how do I translate that percentage into actual amounts (like grams or ounces?)"

    Percentages of my daily food intake. I used percentages because everyone has a different calorie ceiling where we stop losing weight. The ceiling calorie limit usually changes as you lose weight; but the percentage of Protein, Fat and Carbohydrates should remain the same.

    My daily calorie limit is now around 1500 calories; when I weighed 80 lbs more, it was closer to 2000 calories; and at 2000 calories back then I was losing 3-4 lbs a week.  Either way, the grams/oz of Potein/Fat/Carbs that I eat probably won't relate well to you; but percentages can and will.

    By the way, I use a food-tracking program called FitDay, that calculates your food entries into P/F/C, and into grams/oz and percentages, and also gives daily vitamin/mineral counts as well as for individual foods.  It's really quite interesting to compare the nutrition counts of different foods; that way you can see what's really worth eating.  Meat contains a lot more than just protein... it has a lot of essential vitamins and minerals, actually.

    FitDay is free online, but the purchased version is much more convenient; I paid $25 three years ago and consider the money well spent.

    You should track your own food intake to see for yourself what percentages your current diet contains... you might be surprised. Food tracking, whether through FitDay or some other program, is the single most useful thing that helps keep me on track.

    Re Anonymous and "percentages."  This drives me crazy too.  Without a total daily calorie count, percentages are meaningless.  So what if I eat "10%" carbs, if I am noshing on 6000 calories a day?

    To answer your question: yes, you do have to do some simple math.  First, figure out the number of calories in the given percentage, using a hypothetical total daily caloric intake.  40% of 2,000 calories, for example, would be 800 calories.  A carb has roughly 4-5 calories per gram, so that would equate to around 200 grams of carbs.  Protein is similar.  Fat, on the other hand, has 9 calories per gram.  So those 800 calories would be slightly less than 90 grams of fat.

    Once you start doing it, it gets easier.  Practice on food labels!

  • HSL

    3/19/2010 8:11:21 PM |

    Anon - most food values are given as a % of calories.  For example if you are eating 2000 calories/day of which 70% is fat, then you're eating about 155 gms of fat per day (2000 x 0.70 = 1400/9 = 155 gms). Fat has about 9 calories/gm; carbs & protein each have about 4 calories/gm.

    As for "...15 to 18% of what" that would depend on what you're eating.  Three ounces of white fish (raw) has about 16 gms of protein; 3 oz of beef chuck (raw) has about 28 gms of protein.

    That doesn't prove that calories in vs. calories out is faulty.  The calories in vs. calories out concept is simply the theory that you will lose weight if you eat below BMR, regardless of what foods you eat.  The Thermodynamics argument is misapplied to this concept, IMO.

    I was on the cruise and yes, many of the cruisers were overweight.  Some are just starting a low carb lifestyle, and some are not.  I personally have lost over 150 lbs on low carb and maintained that loss for nearly 2 years now.  I consider that a success, however, I am not thin by any means and am working on about 50 more lbs.  I took the advice from many of the speakers, Dr. Davis included, and have worked it into my daily routines.  As a registered nurse, I am aware of nutrition both mainstream and low carb.  I do my research.  I try to eat cleanly most of the time.  Life interferes sometimes, much as is does for anyone who is human and as I know it has for some of the individuals who were on the cruise.  I do believe individuals who are or have been morbidly obese are vastly different from your average American with 30 lbs to lose.  Everything happens on a grander scale.  We lose weight bigger and gain weight bigger.  All I know is I've lost 100+ lbs using the Standard American Diet--twice.  Within a year I gained it back--twice.  Finding a low carb diet has saved my life.  I eat in normal portion sizes, I maintain. Is it for everyone? No.  Is it the only way? No.  But it is one way that works for many people who really need it.

    Really? Strong association? If that's true, then how do you explain this?:

    Hilary, I have not formed an opinion one way or the other on this issue yet, but the study you cite was "Supported in part by the Cattlemen's Beef Board, through the National Cattlemen's Beef Association, and the National Pork Board."

    Re my question as to how to translate percentages of protein, fat and carbs into grams, I should've have asked my trusted friend "google" instead of taking up someone's time here. So please forgive me.

    But Thanks! to those who responded. Your explanations were very helpful.

    Meanwhile, I found a site which will do all that computation for me and thought I'd pass it on.

    Hi I was on the cruise and thoroughly enjoyed it. Sue, Yes I am overweight according to my BMI of 29, I was on the cruise the first year by the second i was 20 pound lighter by the time I got on this years cruise since last year I have lost 54 pound. Yes I am still as you say overweight but I am doing something about it. Sorry I wasn't "normal" for this year but I will be for next year. Snacks were handed out but the message was clear that these are treats and a preferable treat than something high carb and sugar loaded. There were new people there and others who have been doing it a while and of those we are all less than when we started. We had some excellent speakers i.e. Dana Carpender who spends her life educating us how to make foods using our own ingredients she even said you can put weight on eating low carb as we still can make the wrong choices. We all have the same problem with food do we not but we are prepared to be educated by the fabulous speakers who went to help us and gave their time freely to pass on their knowledge.

    A big big thank you to them and you Dr Davis

    Ailsa who came one the cruise all the way from the UK.

    I've been reading your blog for a couple years and really enjoy doing so. I think you've got it wrong on the Atkins diet, though. I don't know where you got your information and I'm pretty sure you didn't read the books. Milk and yogurt aren't on the "diet". Atkins also told you to not eat cured meats. As far as calories are concerned, Atkins also told people to not eat too much! So... I'm having a lot of difficulty with this article in particular & wanted to pipe up. I'll go back to readin' the rest of your blog now. Thanks for all your efforts in keeping this blog up and running. -- Mike

    Dr. Davis, have greatly enjoyed your insights on this blog over the year. Have had your book for a couple of years. Have noticed great benefits from your vitamin D recommendations. When is your updated Track Your Plaque book coming out? I thought it was coming out toward the end of last year? Any ETA on it? Very interested in seeing your recommendations as it relates to diet? Typical recommended breakfasts, lunchs, and dinners?

    This seems consistent with Ray Peat's advice as far as meat meat is concerned- he recommends balancing meat intake with gelatin so as to not get too much iron (hemeprotein afterall) as well as the fact that it has a less inflammatory amino acid profile (muscle is high in tryptophan and histidine wheras gelatin has no tryptophan and lots of glycine and proline...)

    Also he mentions that he always drinks coffee when he eats red meat so as to block iron overload even more!

    Of course he has no problems with milk, butter and cheese consumption but prefers the latter b/c curds have a better amino profile than whey.

    Over the years, I've looked closely at the studies associating red meat with colorectal cancer, and it appears to be impossible from them to separate the effects of modern meat production practices from that of the meat. In other words, it is as likely as not that what's wrong with the red meat is what we put into it, and how it is grown, versus any attribute of the meat itself.

    However, whatever the cause of the problem, it pays to at least limit consumption of red meat that you buy in a supermarket.

    Hi Dr Davis,

    Thanks for sharing your comments. I am a big Atkins Diet follower, and we all need to remind ourselves to keep the intake of "processed" meat & foods to a minimum. Vegetables are a good way to go! Thanks for providing us <a href ="http://atkinsdietinformation.blogspot.com>Atkins Diet</a> followers with such relevant and important information

    Cheers,

    I think it's bizarre to associate ANYONE'S eating habits on a cruise with what their day-to-day life is like.

    My normal food would not be available on a cruise: homemade yogurt and kefir made from fresh raw whole milk mixed with berries, pastured eggs with dark yellow yolks cooked in pastured butter, pastured meat, fresh organic fruits and vegetables, homemade chocolate made with coconut oil, cocoa, almonds and stevia... I don't see a cruise line providing food like this.

    So, I'd probably do sugar-free cheesecake too, or wind up overeating fresh fruit, just cause there'd not be any of my food there.

    When I travel, I do Wendy's burgers using the lettuce as a bun if hitting a drive-through or really crappy salad bars with not much beyond iceberg lettuce.

    Sometimes, you do the best you can with the circumstances... cause to eat really WELL, you pretty much need a kitchen.

    Really some truth to the fact that people from Mediterranean areas are seldom obese despite eating a very high fat diet? Did science get it all wrong before? Was there a national conspiracy to force people to eat boring, healthy foods? Thanks for your good suggestion.

    I haven't eaten meat or dairy in long time. Humans don't need meat or dairy. I think meat is disgusting and I'm glad I don't have to eat it. I've seen meat-eaters B-12 deficient, so this shows eating meat doesn't necessarily make someone sufficient in B-12. Methylcobalamin B-12 works great. Eating red meat apparently increases colon and breast cancer risk. I think meat was meant to be an option, just like grains or legumes. Humans were designed to survive on many different things. Plant foods are affordable and bearable for me - meat is not.

    Overconsumption of dairy products--Dairy products, especially milk, yogurt, cottage cheese, and butter, are potent insulinotropic foods, i.e., foods that trigger insulin release. There can be up to a tripling of insulin (area-under-the-curve) levels. This is not good in a world populated with tired, overworked pancreases, exhausted from a lifetime of high-carbohydrate eating.

    hey guys,
    you out there had some great conversations that help me learn a lot from your, atkins diet, "slow-burn" discussions, meat consumption and being vegetarian.

    Nice exchange of great ideas, keep going guys and thanks Dr. Davis.

    What do you make of this 'physiological insulin resistance' and its role in creeping weight gain on too low carb

    Hi, Lance--

    I've not heard this argument before. If you've got the references for the studies showing this effect, I'd be happy to take a look.

    In real life, I've not seen this play out. People who restrict carbs, lose visceral fat, drop HbA1c, glucose, and insulin. Maintaining the diet does not, over the years, allow recrudescence of the phenomena of insulin resistance.
