Vitamin D as a cardiovascular risk factor gains ground

If you were reading The Heart Scan Blog back in 2007, or read my Life Extension article on vitamin D deficiency as a cardiovascular risk factor, you already knew that vitamin D deficiency is rampant and adds to cardiovascular risk.

Results of a study from the Intermountain Medical Center Heart Institute in Utah bolster the concept that vitamin D deficiency is a cardiovascular risk factor, vitamin D normalization/supplementation reduces cardiovascular risk.

Science Daily reported:

For the first study, researchers followed two groups of patients for an average of one year each. In the first study group, over 9,400 patients, mostly female, reported low initial vitamin D levels, and had at least one follow up exam during that time period. Researchers found that 47 percent of the patients who increased their levels of vitamin D between the two visits showed a reduced risk for cardiovascular disease.


In the second study, researchers placed over 31,000 patients into three categories based on their levels of vitamin D. The patients in each category who increased their vitamin D levels to 43 nanograms per milliliter of blood or higher had lower rates of death, diabetes, cardiovascular disease, myocardial infarction, heart failure, high blood pressure, depression, and kidney failure. Currently, a level of 30 nanograms per milliliter is considered "normal."


Over the past 4 years, people in our program have been enjoying the extravagant benefits of vitamin D restoration. Cardiovascular benefits are becoming better documented and the bone health, cancer-preventing, insulin-normalizing, mood-adjusting, and anti-inflammatory effects likewise.

Dr. Dwight Lundell on omega-3s and CLA

Dr. Dwight Lundell on omega-3s and CLA



An interview with Dr. Dwight Lundell, cardiac surgeon and author of the new book, "The Cure for Heart Disease."


Dr. Lundell comes to us with a unique pedigree. He is a cardiothoracic surgeon practicing in the Phoenix, Arizona, area. Despite having performed thousands of coronary bypass operations, including numerous "off-pump" procedures earning him a place in the Beating Heart Hall of Fame and a listing in Phoenix Magazine’s Top Doctors for 10 years, more recently Dr. Lundell has turned his attentions away from traditional surgical treatment and towards prevention of heart disease and.

In particular, Dr. Lundell is a vocal advocate for omega-3 fatty acids from fish oil and conjugated linoleic acid, or CLA.

When I heard about Dr. Lundell’s unique perspectives, I asked him if he’d like to tell us a little more about his ideas. Here follows a brief interview with Dr. Lundell.



You’re a vocal advocate of the role of omega-3 fatty acids from fish oil in heart disease prevention. Can you tell us how you use it?

In my book, I recommend 3 g of fish oil daily. This would normally yield about 1000 mg of EPA and DHA depending on the concentration of the supplement. This is approximately the dose that reduced sudden cardiac death by 50%, and all cause death, by 25% in patients with previous heart attack.

In patients with signs of chronic inflammation such as heart disease, obesity, arthritis, metabolic syndrome or depression or in those patients with elevation of CRP, I would recommend higher doses, 2000 to 3000 mg per day of EPA and DHA. The FDA has approved up to 3400 mg for treating patients with severely elevated triglycerides.

I personally take a 2000 mg EPA and DHA per day because I have calcium in my coronary arteries.




Of course, in the Track Your Plaque program we track coronary calcium scores. Do you track any measures of atherosclerosis in your patients to chart progression or regression?

Carotid ultrasound with measurement of IMT [intimal-medial thickness] has been shown to be a good surrogate marker for coronary disease, as has vascular reactivity in the arm. CT scanning with calcium scoring is a direct marker of coronary disease. CT does not differentiate between stable or unstable plaque but there is no good noninvasive way of doing this.

The dramatic value of CT scan calcium scoring is to demonstrate to people that they actually do have coronary disease and to motivate them to make the necessary lifestyle and nutritional changes to reduce it. CT scan with calcium scoring is a direct way to measure the progression or regression of coronary artery disease. If there is a choice between a direct measurement and indirect measurement, always choose the direct method.

Every patient treated with CLA in my clinic, experienced significant reductions in C-reactive protein. These patients were also on a weight-loss program, so I can't prove whether it was the CLA or the weight-loss that improved their inflammatory markers. In the animal model for arteriosclerosis, CLA has a dramatic effect of reducing and preventing plaque. This has not yet been proven in humans.

Normally, when people lose weight 20% or more of the loss is lean body mass (muscle) this lowers the metabolic rate and frustrates further weight-loss. My patient, from teenagers to retirees, lost no lean body mass and continued to have satisfactory weight-loss when CLA was used as part of the plan.



In reading your book, your use of conjugated linoleic acid (CLA) as a principal ingredient struck me. Can you elaborate on why you choose to have your patients take CLA?

My enthusiasm for CLA is based on:

1) Safety?this is of paramount importance. Animal toxicity studies have been done, as well as multiple parameters measured in human studies, both of these are well reviewed recently in the American Journal of Clinical Nutrition (2004:79(suppl)1132s). CLA, a naturally-occurring substance, is not toxic or harmful to animals or humans. The only negative report is by Riserus in Circulation (2002), where he found an elevated c- reactive protein; however, he used a preparation that is not commercially available and not found in nature as a single isomer.

2) Effectiveness?also critically important. A recent meta-analysis [a reanalysis of compiled data] in the American Journal of Clinical Nutrition (2007; 85:1203-1211) demonstrated the effectiveness of CLA in causing loss of body fat in humans. The study also reconfirmed the safety of CLA.

Since we now know that atherosclerosis is an inflammatory disorder, any strategy that reduces low-grade inflammation without significant side effects would seem to be beneficial in the treatment and prevention of atherosclerosis. CLA not only has antioxidant properties, but it modulates inflammatory cascade at multiple points. CLA reduces PGE2 (in much the same way as omega-3) CLA also has been shown to reduce IL-2, tumor necrosis factor-alpha and Cox–2. It reduces platelet deposition and macrophage accumulation in plaques. It also has some beneficial effect in the PPAR [peroxisome proliferator-activated receptors, important for lipid and inflammatory-mediator metabolism] area.

Part of the effect of CLA may be because it reduces fat mass and thus the amount of pro-inflammatory cytokines produced by fat cells.

I reiterate and fully admit that CLA has not been shown to have any effect on atherosclerosis in human beings. However, the results in the standard animal models for atherosclerosis (rabbits, hamsters,APO-E knockout mice) are very dramatic.

From all I know, it appears that the effective dose for weight loss and the animal studies in atherosclerosis would be equal to about 3 g of CLA per day. The anti-inflammatory properties of CLA seem to work better in the presence of adequate blood levels of omega-3.



I’m curious how and why a busy cardiothoracic surgeon would transform his practice so dramatically. Was there a specific event that triggered your change?

The transition from a very busy surgical practice to writing and speaking about the prevention of coronary disease has not been particularly easy, but it has been very interesting. I can't really point to any specific epiphany, it was a general feeling of frustration that we were not making any progress in curing heart disease, which is what I thought I was doing when I began my medical career.

Of course, I enjoyed the technical advances, the dramatic life-saving things that you do and I did on a daily basis. American medicine is spectacularly good at managing crises and spectacularly horrible at preventing those crises.

The lipid hypothesis is old and tired, even the most aggressive statin therapy reduces risk of heart attack by about 30% in a relatively small subset of people. It's interesting that we're now looking at statins as an anti-inflammatory agent.


Thanks, Dr. Lundell. We look forward to future conversations as your experience with CLA and heart disease prevention and reversal develops!

    I was under the impression that CLAs only exist in animal products and that beef is particularly rich in CLAs.  I also understood that CLAs are a form of transfat, although perhaps a beneficial form, if there is such a thing.  Do you think that adding CLA is helpful for regression of plaque?  Does TYP recommend doing so?  If so, should the CLA be via a supplement and what dosage is typical?

  • Dr. Davis

    9/8/2007 1:07:00 AM |

    We are putting together a clinical trial to examine this issue. I don't have any preconceived notions over whether CLA will work or not. The animal data for reversal of atherosclerosis is fabulous, almost too good to believe.

    The human data on weight loss is, in aggregate, modestly promising. But will it reverse atherosclerosis in humans? We're going to try and find out.

  • Jill Doss

    6/5/2008 12:40:00 AM |

    It is my understanding that CLAs are a derivative of Parent Omega 6. I have read that the correct proportions are two parts omega 6 to one part omega 3.  This is referred to as Essential Fatty Acids (EFAs).  Lack of EFAs impede the use of oxygen and oxygenation is crucial to the miochondria of a cell.  I'm interested to see what your comments are on EFAs.

    @anon & David,

    I didn't read the whole report of the deliberations, but from reading the first one, several observations can be made:
    -Dr Lundell had retired from thoracic surgery at the time of the hearings.
    -The hearings concerned complaints about certain high risk surgeries done by Dr Lundell, as they are done by all thoracic surgeons.
    -None of this has anything to do with a nutritional approach to halting and reducing CVD.

Can I see your linea alba?

Can I see your linea alba?

As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba.

Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen.

It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors.

    I've been wheat/sugar/flour etc free for about 4 months and although I didn't want to drop weight, it just happened; fast. About a month ago I dropped the rest of the grains from my diet and even though my weight stayed the same, the small love handles I had-or extra fat around the waist- disappeared. It wasn't much to begin with, but it's pretty much gone.

    Your "ideal" weight should be what you weighed when you were 25 yrs old....+/- 10lbs, at the most.
    Women, post gravida, usually....usually...put on about 5-10 lbs after childbirth...that's reasonable...due to hormonal influences.
    But men, you should be at your 25 yr old weight
    Plus, that's when the human body fully matures in all neuromuscularoskeletal body areas.
    Makes sense to be that weight...unless you are eating grains!

    Dropping the wheat made a huge improvement on my lipid profile. The only draw back is that I was already pretty thin with 18% body fat, now I'm probably down to 8%. People have commented that I look "too" thin and my cheeks have kind of a sunken look.

    I weighed 60kg at 183cm when I was 25. I now weigh 74kg which is far more appropriate.

    It is also possible to be of "normal" weight and have very high body fat and very low muscle mass.

  • Dr. William Davis

    11/4/2010 12:14:03 PM |

    Also factor in relative muscle mass. I am a big believer of strength training, e.g., Fred Hahn's "slow-burn" techniques. Not only do you feel better, you enhance insulin responsiveness, increase HDL, reduce triglycerides, and increase bone density. However, this will increase the crude BMI measure, as well as body weight.

    It also heightens the likelihood of seeing your linea alba.

  • Sifter

    Oh, I don't know... I dated a few women who had the linea alba readily visible, and their diet was mostly junky microwavable frozen food dinners and fast food (when I didn't take them out, that is Smile
    I think the Linea alba being visible is simply a benefit of fewer caloris, not the makeup of those calories.

    This is extremely unlikely unless you are a world class endurance athlete. You are probably still 14-15% body fat. Even very thin people can have surprisingly high body fat levels.

    I have a friend who is an Australian  national-level middle-distance runner. He has 15% body fat.

    When you lose weight by caloric restriction (including LC diets) you will nearly always lose (a lot) of muscle as well as fat.

    The only way to prevent muscle loss and bulk up is to undertake a resistance training program. Without this protein is just broken down and excreted in the urine.

Slash carbs . . . What happens?

Slash carbs . . . What happens?

Cut the carbohydrates in your diet and what sorts of results can you expect?

Carbohydrate reduction results in:

Reduced small LDL--This effect is profound. Carbohydrates increase small LDL; reduction of carbohydrates reduce small LDL. People are often confused by this because the effect will not be evident in the crude, calculated (Friedewald) LDL that your doctor provides.

Increased HDL--The HDL-increasing effect of carbohydrate reduction may require 1-2 years. In fact, in the first 2 months, HDL will drop, only to be followed by a slow, gradual increase. This is the reason why, in a number of low-carb diet studies, HDL was shown to be reduced.--Had the timeline been longer, HDL would show a significant increase.

Decreased triglycerides--Like reduction of small LDL, the effect is substantial. Triglyceride reductions of several hundred milligrams are not at all uncommon. In people with familial hypertriglyceridemia with triglyceride levels in the thousands of milligrams per deciliter, triglyceride levels will plummet with carbohydrate restriction. (Ironically, conventional treatment for familial hypertriglyceridemia is fat restriction, a practice that can reduce triglycerides modestly in these people, but not anywhere near as effectively as carbohydrate restriction.) Triglyceride reduction is crucial, because triglycerides are required by the process to make small LDL--less triglycerides, less small LDL.

Decreased inflammation--This will be reflected in the crude surface marker, c-reactive protein--Yes, the test that the drug industry has tried to convince you to take statins drugs to reduce. In my view, it is an absurd notion that you need to take a drug like Crestor to reduce risk associated with increased CRP. If you want to reduce CRP to the floor, eliminate wheat and other junk carbohydrates. (You should also add vitamin D, another potent CRP-reducing strategy.)

Reduced blood pressure--Like HDL, blood pressure will respond over an extended period of months to years, not days or weeks. The blood pressure reduction will be proportion to the amount of reduction in your "wheat belly."

Reduced blood sugar--Whether you watch fasting blood sugar, postprandial (after-meal) blood sugars, or HbA1c, you will witness dramatic reductions by eliminating or reducing the foods that generate the high blood sugar responses in the first place. Diabetics, in particular, will see the biggest reductions, despite the fact that the American Diabetes Association persists in advising diabetics to eat all the carbohydrates they want. Reductions in postprandial (after-eating) blood sugars, in particular, will reduce the process of LDL glycation, the modification of LDL particles by glucose that makes them more plaque-causing.


You may notice that the above list corresponds to the list of common plagues targeted by the pharmaceutical industry: blood pressure, diabetes (diabetes being the growth industry of the 21st century), high cholesterol. In other words, high-carbohydrate, low-fat foods from the food industry create the list of problems; the pharmaceutical industry steps in to treat the consequences.

In the Track Your Plaque approach, we focus specifically on elimination of wheat, cornstarch, and sugars, the most offensive among the carbohydrates. The need to avoid other carbohydrates, e.g., barley, oats, quinoa, spelt, etc., depends on individual carbohydrate sensitivty, though I tend to suggest minimal exposure.

    I've eliminated almost all sugar, and all refined grains, but I still  eat brown rice, oatmeal, and whole spelt bread. On my recent VAP test, my triglycerides were 78, HDL was 63, and my LDL was Pattern A (large, buoyant LDL). Also, my Cardiac C Reactive Protein was .84. I'm concluding that some whole grains are appropriate for me, and I use the blood glucose monitor to monitor postprandial glucose.

    Dr. Davis, following your advice as well as several other clarion voices in the nutritional wilderness, over the last 9 months I went from:
    HbA1C 6.6, Fasting glucose 125mg/dl, BP135/85, LDL nearly 200, HDL below 30, body weight 245 (6ft tall, 40 in waist) on a mainly carb diet, to:

    HbA1C 5.5, Fasting glucose 105mg/dl, BP115/70, LDL nearly in 1/2, HDL above 65, body weight 204 (still 6ft tall, but a 33 in waist) on a very low carb diet.

    I've got 4 friends - all males in their 40s - who have also moved their personal numbers in these directions by greatly reducing carbs.  I'm trying to get my severely type II diabetic father to follow the same regimen, but his Medicare provided dietitian is fighting me every step of the way, with a diet based upon bread!  The struggle continues.

    In people with impaired glucose tolerance, slashing starch too may indeed be beneficial.  But is there any evidence that slashing starch benefits people who have a healthy liver and pancreas?  In such people, I suspect slashing starch is just treating numbers and has nothing to do with health.  Otherwise, how do you explain Kitava, Peru, and Asia?

  • jandro

    3/26/2010 8:25:13 PM |

    Sometimes I think that the results given with these studies are mostly due to the reduction of grains (lectins) and refined sugar and not carbohydrates themselves. I want to believe it is as simple as reducing carbohydrates but it doesn't explain how populations like Kuna and Kitava have good health markers even though they eat a high carb diet. Dr. WD, do you have any ideas related to this specific topic?

    Actually, in the study reviewed in the post below, a 2-week replacement of refined carbs and sugars with dietary fat (mostly saturated) and cholesterol, led to a significant increase in HDL (14 percent increase in HDL from baseline for men).

    http://healthcorrelator.blogspot.com/2010/02/want-to-improve-your-cholesterol.html

    That was two weeks only.

    In my own experience, higher consumption of saturated fat and dietary cholesterol has immediate effects on HDL, and those effects are especially strong with elimination of refined carbs and sugars.

    One thing I don't understand is if all these benefits are independent or if they are all linked to glucose level.
    If a particular carbohidrate causes little glucose spike will it still cause the other poblems?
    Or if carbohidrate intake is followed by intense physic actvity which seems to take BG down does it still causes all the other problems?

    Welcome to Low Carb Dr. Davis!  From now on, your life will never be the the same

    8-Smile

    In addition to what you have listed, which I can confirm in 100%, more beneficial effects will become apparent, such as:

    - self-healing of teeth with no need for dental intervention, and roughly twice as fast healing of broken bones.

    - healing of common cardiovascular diseases (arteriosclerosis, cardio myopathy and arrhythmia)

    - rapid self-healing of hepatic diseases (i.e post hep-C cirrhosis healed in 6 months),

    - improved kidney disease recovery (I heard of a patient  surviving on Optimal Diet without dialalysis with only 1/3 of 1 kidney left)

    - normalization of one's body weight (obese loose, underweight gain),

    - much stronger immune system (for instance, I never had a flu since yr 2000, before - twice a year)

    - stronger more benign reaction to stress, no more paralyzing panic, no more total body vascular contraction and probably related better resistance to cold temperature.  

    - no need to drink water frequently (fat metabolism releases water as an end product)

    - never feel hungry again, no need to snack, eating once or twice a day becomes the norm.   For me no breakfast, no supper, only lunch and dinner, typically.  

    - improved ability to hold breath longer when diving, generally we also naturally breath less frequently,

    - different (improved) mood, subtle changes in the way one thinks, solves problems and react to life events, as no doubts, you will find out...  8-Smile

    Daniel, I've tested my own blood glucose before and after meals and it's normal. However, I cut way back on all carbs a couple of months ago, and now eat around 47 grams of carbs per day. Results: I find that I don't need Sudafed or acid blockers at all now and I rarely take ibuprofin (an anti-inflammatory). The twinge in my shoulder and knee are gone. I've lost 10 pounds while working out *less.* I seldom get headaches, and when I do, they're mild. I also need a lot less sleep.

    Should anyone care for details, I've chronicled my experience in my blog.

    jandro - it is a very good question.  I wonder too but the studies I am reading (see for example Lancet. 1996 ) seem to indicate that carbohydrate reduction is beneficial in all cases, including healthy rural young populations.  

    I see it now in the same light as for example alcohol consumption: if you are healthy and young, a  harm may be minimal and some wine  (in moderation) may even provide you with some calories and micronutrients (i.e. resveratrol), but why bother consuming all that starchy and sugary plant food that we are not that well adapted for, that is useful only if we have nothing else to eat and that was probably meant for us only as a temporary food to get us over some rough periods of fauna decline.

      Since there is so little modern research done specifically on this subject we are still largely in the domain of hypotheses and theories. However not all that is speculative.  For example existing archaeological research does show us that paleolithic human diet consisted typically over 2/3 of meat!  We are talking about millions of years of human adaptation.

    Dr. Davis,  I forgot to add to my above list of benefits the following point:

    - reliable improvement (in almost every case) in treating the autoimmune diseases such as rheumatoid arthritis, asthma, eczema, psoriasis etc,

    - intestinal disease (Crohns, IBS , very high fat only!).  

    - Multiple sclerosis (not 100% especially if nerve damage is too advanced but improvement in most cases)

    There is a lot of patient cases (hundreds) of the above disease reported by Dr. Jan Kwasniewski, from his medical practice in the 1980-ties, described in his books, especially "Homo Optimus" and "Optimal Nutrition".  

    I think you will find those books extremely interesting, highly recommended.

    Um Heretic.. I think Dr. Davis has been low carb for quite a while now. No need to welcome him to something he's already quite familiar with Smile

    Stan, thanks for your response:

    I read the abstract of the study you link and don't see how it is related to what I mentioned. It is comparing a vegetarian population with one that eats around a pound of fish a day. Seriously, is there a question there as to which is healthier? I also don't think they are healthier primarily because they consume less carbohydrates, but rather because they consume a pound of fish a day compared to no animal fat/flesh in the other group.

    If you read my original post again you will notice I am not saying a vegetarian diet (in fact, I eat over a pound of meat a day), I am just questioning whether the true problem is carbohydrates or if it is lectins, assuming you have a generous amount of animal fat and protein. I personally eat around 20% carbs, mostly coming from tubers and squashes as I find fruits too sweet (I agree that fructose should be reduced). Generally eat one piece of fruit a day.

    I also don't see any evidence to your claim that humans are not adapted to plant foods. We are omnivores, and that's how we have succeeded. We are adapted to a diet similar to what equatorial hunter gatherers have, since we evolved in a similar environment. People bring many archeological references of sites located outside of Africa not realizing that the environment outside of Africa is nearly as new to us as grains are. Most HGs living in Africa have plant food present on their diet. The information you tell yourself claims 2/3 of our diet was meat, what happened to the other 1/3?

    And what if someone goes really lowcarb (mostly meat) and his LDL rises up to 500? No info on the the LDL size. The remaining bloodwork results are  really good. Is this something to be worried about?

    Hmm, well I eliminated wheat and all glutens from my diet in January 2009. I eliminated sugar at the same time. I also eliminated high Omega-6 vegetable oils. I basically eat low carb. I love to use coconut oil. Smile I've lost over 100 pounds.

    But my cholesterol just goes UP and UP! At least total and LDL - HDL remains in the 58-62 range and triglycerides remain in the 60-70 range. But Total cholesterol went from 229 6 months ago to 279 3 months ago, to 280 today, and LDL went from 165 6 months ago, to 190 3 months ago, to 206 today.

    And I can't understand why! Of course my doctor is rabid to put me on stations and crazy with me that I refuse, and looks at me cross-eyed when I request an NMR/VAP test for LDL particle size.

    But it still bothers me that it continues to go up and up and up, as I feel like I'm doing all I can to lower it. I was also diagnosed with Hashimoto's 6 months ago and put on 50 mcg of Levoxyl. Then three months ago it was upped to 75 mcg. Today it was upped to 88 mcg.

    Slashing carbs eliminating the bad stuff sure is not helping my total numbers, which means a huge argument with the doctor every visit, and I hate to argue. :-(

    I'm so glad I found this post!. I've had a group of clients take on paleo eating as a 6 week trial, doing so has naturally decreased their carbs. I had each person do before and after blood tests and I was concerned that 80% had a reduction in HDL. They also had reductions in Triglycerides and LDL and blood pressure and significant weight loss - but couldn't figure this one out. Thanks so much for keeping us informed of what goes on for your clients, so I know what is happening with mine is normal.

    By the way here are some of the results in people's own words
