Cartoon humor: A Prescription for Health!

 

prescription-for-exercise-cropped

Hat tip to Tommy Wood MD, PhD for introducing me to this great cartoon.

So what would happen if your doctor prescribed this? Would you be shocked? Would you follow the advice? Sadly few doctors make such recommendations as explicitly as this cartoon and fewer patients follow the advice.

How important are the elements in this advice?

They are essential. We too often focus on dietary concerns at the expense of ignoring other important low hanging fruit. Early morning  outdoor exercise with exposure to natural light in a green space, even on a cloudy or rainy day, is essential for health. Why? There are many reasons. Click the link above to read fitness expert Darryl Edward’s discussion with references. In fact outdoor exercise in a greenspace is more beneficial than the same exercise indoors. The reasons are many, including but not limited to Vitamin D production.

Early daytime exposure to natural outdoor light helps to maintain our Circadian rhythm and align the biologic clock in all of our cells and organs with the central biological Circadian clock in our brain. Most folks do not know that we have a biologic clock deep within our brain and that all the organs and cells of our body also have clocks. They all need to be synchronized with each other and with the sun for optimal health. When they are not synchronized bad things happen. Night shift workers and other folks with disturbed sleep have higher rates of cancer , depressionhypertension, heart attack and stroke.

Maintaining our circadian rhythm is vital to achieving adequate high quality restorative sleep. In turn, obtaining adequate restorative sleep contributes to lower cardiovascular disease risk in addition to four traditional lifestyle risk factors.

Exposure to artificial light at night disrupts our circadian rhythm and impairs the onset of sleep.

In medical school I learned that our retina has two cell types, rods and cones. But advances in science have revealed a  third cell type called retinal ganglionic cells. 

These cells are  particularly sensitive to blue light and directly connected to our central biological clock . Exposure to artificial light, especially from TV screens, computers, cell phones and other electronic devices after sunset disrupts our sleep cycle and delays the onset of sleep. That is why wearing blue light filtering glasses in the evening helps many folks to improve their sleep quality and duration.

Sleep deprivation for even one night causes elevation in interleukin 6 levels the following day. Interleukin 6 suppresses immune function and excessive levels cause bone and tissue damage (especially cardiovascular). Sleep deprivation  increases  Stress hormones (cortisol, adrenalin), decreases prolactin and Growth hormone , and decreases the nightly production of ATP .

Melatonin , often called the sleep hormone, is produced most abundantly during restorative sleep and essential for tissue healing, immune function, cancer prevention, and defense against tissue oxidation. These are just a few of the roles melatonin and sleep cycles play in determining our health..

So exercise outdoors in a green space daily to help synchronize your biologic clock with the sun, dim the lights in the evening and if you must watch TV or work on electronic devices before bed wear Blue Light filter glasses .

Of course eating an abundance of colorful fresh organic vegetables and fruits, and practicing some stress reduction techniques every day are equally important and essential to health and functional status.

Finally, not mentioned in the cartoon above is another healthy lifestyle choice, intermittent fasting (IF). IF will be discussed in the next post.

Until then, sleep well, exercise regularly out doors in a green space environment, eat clean, learn and practice some regular stress reduction techniques and read the next post about IF.

Sugar Industry paid Harvard researchers to trash fat and exonerate sugar!

By now most of you have already heard about the study published in JAMA that reveals an unsavory historical scenario wherein the sugar industry  funded an academic review paper that diverted the medical community’s attention from sugar as a vector for disease and erroneously placed it on saturated fat and cholesterol consumption. You can read about it by clicking on the following link.

How the Sugar Industry Shifted Blame to Fat – The New York Times

Here is a quote from the above cited article in the NY times:

The internal sugar industry documents, recently discovered by a researcher at the University of California, San Francisco, and published Monday in JAMA Internal Medicine, suggest that five decades of research into the role of nutrition and heart disease, including many of today’s dietary recommendations, may have been largely shaped by the sugar industry.

Here is the abstract of the article published in JAMA (Journal of the American Medical Association).

Sugar Industry and Coronary Heart Disease Research:  A Historical Analysis of Internal Industry Documents | JAMA Internal Medicine | JAMA Network

Early warning signals of the coronary heart disease (CHD) risk of sugar (sucrose) emerged in the 1950s. We examined Sugar Research Foundation (SRF) internal documents, historical reports, and statements relevant to early debates about the dietary causes of CHD and assembled findings chronologically into a narrative case study. The SRF sponsored its first CHD research project in 1965, a literature review published in the New England Journal of Medicine, which singled out fat and cholesterol as the dietary causes of CHD and downplayed evidence that sucrose consumption was also a risk factor. The SRF set the review’s objective, contributed articles for inclusion, and received drafts. The SRF’s funding and role was not disclosed. Together with other recent analyses of sugar industry documents, our findings suggest the industry sponsored a research program in the 1960s and 1970s that successfully cast doubt about the hazards of sucrose while promoting fat as the dietary culprit in CHD. Policymaking committees should consider giving less weight to food industry–funded studies and include mechanistic and animal studies as well as studies appraising the effect of added sugars on multiple CHD biomarkers and disease development.

This disturbing conspiracy reveals yet another industry sponsored distortion of science which had great impact on the health of our nation. The impact is accelerating today as the epidemics of obesity and diabetes rage out of control. But sugar consumption has not just been tied to obesity, diabetes, heart attacks and strokes. Sugar added foods and beverages have likely contributed to dementia,  many forms of cancer and other chronic debilitating diseases. Sugar and refined carbohydrates mediate these effects by increasing systemic inflammation and contributing to insulin resistance. Inflammation and insulin resistance are pathways to many disease processes. Metabolic syndrome (pre-diabetes) is the hallmark combination of multiple abnormalities with insulin resistance as the underlying root cause. Prolonged insulin resistance leads to type 2 diabetes and contributes to heart attacks, strokes,  cancer and dementia. In fact dementia is often referred to as type 3 diabetes, mediated in large part by insulin resistance in the brain.

STATINS OF NO BENEFIT AGE 80 AND UP, even after a heart attack!

Finally IT HAS BEEN LOOKED AT AND TRUTHFULLY PUBLISHED, statin drugs for individuals 80 years of age and older  WITH DOCUMENTED HEART DISEASE SHOWS NO BENEFIT, EVEN AFTER A HEART ATTACK

Here is the abstract from the study

Statin Therapy and Mortality in Older Adults With CAD
Abstract
Objectives: To examine the effect of statins on long-term mortality in older adults hospitalized with coronary artery disease (CAD).
Design: Retrospective analysis.
Setting: University teaching hospital.
Participants: Individuals aged 80 and older (mean aged 85.2, 56% female) hospitalized from January 2006 to December 2010 with acute myocardial infarction (AMI), unstable angina pectoris, or chronic CAD and discharged alive (N = 1,262). Participants were divided into those who did (n = 913) and did not (n = 349) receive a discharge prescription for a statin.
Measurements: All-cause mortality over a median follow-up of 3.1 years.
Results: Participants treated with statins were more likely to be male, to have a primary diagnosis of AMI, to have traditional cardiovascular risk factors, and to receive other standard cardiovascular medications in addition to statins. In unadjusted analysis, statin therapy was associated with lower mortality (hazard ratio (HR) = 0.83, 95% confidence interval (CI) = 0.71–0.96). After adjustment for baseline differences between groups and propensity for receiving statin therapy, the effect of statins on mortality was no longer significant (HR = 0.88, 95% CI = 0.74–1.05). The association between statins and mortality was similar in participants aged 80 to 84 and those aged 85 and older.
Conclusion: In this cohort of older adults hospitalized with CAD, statin therapy had no significant effect on long-term survival after adjustment for between-group differences. These findings, although preliminary, call into question the benefit of statin therapy for secondary prevention in a real-world population of adults aged 80 and older and underscore the need for shared decision-making when prescribing statins in this age group.

In layman’s terms. This study compared patients aged 80 and older who were hospitalized with documented coronary artery disease and compared those sent home on statins and those sent home without a prescription for statins. There was no difference in death rates between the two groups. The use of statins in this situation (known heart disease) is referred to as secondary prophylaxis. Secondary prophylaxis would be expected to have greater risk reduction when compared to primary prophylaxis (no know heart disease).

I have advocated against the use of statins in primary prophylaxis. Statin Guidelines, one step forward, two steps backwards | Practical Evolutionary Health

The data in this study shows no protection from statins when used for secondary prophylaxis (higher risk group) for age 80 and above.

Why do our tax dollars continue to subsidize death, disability and disease?

Yesterday I posted a comment on Medscape after reading an article Longtime Dietary Fat Advice Unsupported by Data: Analysis . Medscape is a website with articles and news written for physicians and other health professionals. Anyone can access this information by creating a user name and password, there is no fee.

Here is my comment. It is long and technical. I will provide an explanation in lay terms after quoting myself.

Sugar, especially HFCS (high fructose corn syrup), used in so many foods is more inflammatory than saturated fat. Grass fed meat from ruminants has a fatty acid mix that is exactly the same as wild game, which we evolved to eat, along with tubers, green leafy vegetables, and fruit in season. Excess refined fructose intake AND use of modern refined “vegetable oils” along with non-healthy grains combine to cause excess caloric intake, NAFLD (non-alcoholic fatty liver disease), obesity, metabolic syndrome and CAD (coronary artery disease). N6 PUFA (omega six polyunsaturated fatty acids) are easily oxidized. N3 PUFA (omega 3 fatty acids) despite greater number of double bonds are protected from oxidation in cell and Lipoprotein membranes by plasmalogens as opposed to linoleic acid which is not easily  incorporated into plasmalogens. The PUFA in vegetable oils (linoleic acid) is the FA (fatty acid) that is oxidized on LDL particles and remnant particles, stimulating monocytes to transform to macrophages and then foam cells. The USDA, ADA and AHA have had it upside down for decades and they still fail to admit folly. We evolved for > 1 million years without grains and they have contributed to disease. Per calorie fresh vegetables have five times the amount of fiber compared to whole grains. We do not need grains and would be better without them. They contain anti-nutrients and wheat, hybridized in the 1980s to a storm resistant dwarf plant, now has 50 times more gluten/gliadin than the old wheat. This has generated more gluten intolerance and celiac. Our greatest nutritional threats to public health include refined sugar, carbohydrates predominantly from grains and refined vegetable oils. Vegetable oils are not healthy, we did not evolve to eat them. N3 FAs are anti-inflammatory but have been competing in our diets with a sea of inflammatory N6 PUFA from unnatural refined and easily oxidized “vegetable oils”. Even though PUFA can reduce LDL-C they wreak havoc by creating ox-LDL particles which initiate the cascade of atherosclerosis. Substituting SFA (saturated fatty acids) with PUFA results in increased levels of Lp(a) and oxLDL in humans, not a good thing. Close the feed lots, stop government subsidy of corn, wheat, dairy and soy, eat meat from grass fed ruminants, wild seafood, fresh organic vegetables and fruits in season. Nibble on tree nuts. Stop creating carcinogens with high dry heat cooking methods and we will watch obesity, insulin resistance, metabolic syndrome and atherosclerosis melt away.

That was my comment. Here is some explanation.

I have previously discussed the pro-inflammatory nature of refined “vegetable oils”. “Vegetable oils” are actually not from vegetables, they are from grains, seeds and legumes. The two major sources of excess omega six polyunsaturated fats in the American diet are corn oil and soy oil marketed by various brand names such as Wesson. They are major components of margarine and other butter substitutes and are present in most salad dressings. Most salad dressings sold in our supermarkets contain high levels of easily oxidized unhealthy refined “vegetable oils” and HFCS. The use of these salad dressings converts a healthy salad into a vector for disease.

The major source of caloric sweeteners in our food and beverages is high fructose corn syrup. Both corn (oil and sugar) and soy predominate our processed food supply because they are cheap. They are cheap because our tax dollars subsidize their production. This subsidy started during the Nixon administration. Once a food subsidy is put in place it is very difficult to eliminate, Big Agriculture provides a deep pocket for lobby money and our elected officials from the mid-west bread-basket respond to $$.

Another major source of disease causing elements in the standard American diet is highly refined flour from wheat. Doctors Davis and Perlmutter discuss the problems associated with wheat-flour foods in their books Wheat Belly and Grain Brain respectively. The production of wheat has also been subsidized since the Nixon administration.

Wheat is not what it used to be. A new dwarf hybrid wheat has predominated the US market since the 1980s. Bread and pasta are not what they used to be when great grand-mother made her own bread and pasta in the kitchen from coarsely ground whole flour. But even if we all went back to making our own whole-grain bread and pasta from locally ground pre-1980s wheat, bread, pasta and pastry would still present a health risk because of issues related to intestinal permeability, auto-immune disease (now epidemic in the USA), and the presence of nasty lectins and phytates (discussed in my manifesto and previous posts).

The Medscape comment quoted above describes  adverse consequences caused by replacing saturated fat in the diet with “vegetable oils”. This is a complex subject and I will try to be brief for now but promise to expand on this in a future post.

Many factors contribute to atherosclerosis, heart attack and stroke. Sedentary lifestyle, stress, inadequate restorative sleep, smoking and poor dietary choices top the list. These factors also contribute to obesity, diabetes, metabolic syndrome, insulin resistance and many cancers.

DIETARY FACTORS:

The combination of sugared foods and beverages (predominantly sweetened with HFCS), refined flour foods, and excess consumption of the PUFA in “vegetable oils” TOGETHER  contribute to the formation of plaque in the walls of our arteries (atherosclerosis).

How does this happen?

LDL (low density lipoprotein) is a particle that transports cholesterol and triglycerides through our blood to our organs. This particle is comprised of a core and a surrounding membrane.  Here is a picture.

LDL 2

The core contains cholesterol in a storage form (esters) and triglycerides. The outer membrane includes a large protein called apoprotein B-100, “free” cholesterol molecules and phospholipids. The phospholipids contain fatty acids, including PUFA.

LDL has been demonized as “the bad cholesterol” and that demonization has mislead the public.

hdl_ldl good guy bad guy

LDL is the major lipoprotein in our blood but there are others that have different names.

Cholesterol is cholesterol, whether it is carried in LDL or HDL. When carried in the core of a lipoprotein it is carried as a cholesterol ester. 80% of the cholesterol in an LDL particle is carried as an ester in the core. 20% is carried as “free” cholesterol on the outer surface or membrane.

LDLand cholesterol molecule

HDL (high density lipoprotein) is smaller and denser. HDL has been called “the good cholesterol”, another misnomer.

HDL particles, when they are functioning correctly can protect us from atherosclerosis but in patients with diabetes, obesity, and insulin resistance, HDL particles do not function well and in fact probably contribute to disease. (More about that in a future post)

But back to LDL.

Although the risk of cardiovascular disease is correlated with the amount of cholesterol carried by LDL in our blood (referred to as LDL-C), the total amount of cholesterol shuttled by LDL particles is much less relevant than one would be led to believe given the great use of statin drugs to lower LDL-C.

The short version is as follows.

Compared to LDL-C, a much better predictor of cardiovascular disease is the amount of “modified” LDL particles circulating in the blood. Oxidized LDL particles are one form of “modified LDL”. LDL can also  be modified by excess blood sugar levels (especially from HFCS). This modification is referred to as glycosylated or glycated LDL. In this latter form of modification, the major protein on the outer membrane of the LDL particle (apo B 100 in the picture above) becomes attached to a sugar and the result is an LDL particle that is not easily cleared by normal processes. The modified LDL is not “recognized” by the LDL receptors that act as entry points into our cells for proper processing. The result is that the glycated LDL particles circulate longer and are more likely to use up their anti-oxidants (Vitamin E and  Co-enzyme Q 10).

As a result glycated LDL are more likely to become oxidized. That is not good because oxidized LDL sets up a cascade of unhealthy events.

The portion of the LDL particle that becomes oxidized is the fat (fatty acid) from “vegetable oil”, specifically the fatty acid called linoleic acid. This fatty acid has two double bonds making it more likely to be oxidized than for example oleic acid, the major fatty acid in extra virgin olive oil which has only one double bond.

The double bonds between the carbons in the fatty acids are unstable and easily oxidized. The single bonds in saturated fat do not get oxidized.

All other things being equal (and you will see that they are not), the more double bonds in a fatty acid the greater chance for oxidation.

Here is a picture showing the linoleic acid, also called linoleate, on the outer membrane of the LDL particle.

LDL with linoleate

And here is a picture that shows the phospholipids that contain the linoleic acid.

LDL 3

Let’s say it again. The fatty acid found in “vegetable” oil, linoleic acid, is easily oxidized because it has two double bonds.

Saturated fats are not oxidized because they contain no double bonds.

The part of the LDL particle that becomes oxidized is the fatty acid that comes from “vegetable oils”.

A particular kind of immune cell (white blood cells called monocytes) have  special receptors for oxidized LDL particles. When ox-LDL are “seen” by these monocytes, the monocytes become transformed into macrophages. Macrophages are designed to destroy bacteria that invade our bodies. The oxidized LDL particles resemble the structures of invading bacteria. The macrophages, with very specialized receptors for oxidized LDL, “swallow” the LDL particles and release toxic chemicals to destroy “the invader”.  The macrophages then become “foam cells” in the walls of our arteries, initiating the creation of plaque. Here is a picture.

ldl_mechanisms oxidation in vessel wall

This picture depicts the oxidation occurring in the wall of the artery after LDL particles have penetrated the wall. However LDL particles can and do become oxidized while still circulating in the blood and these oxidized particles can stimulate monocytes to transform into macrophages and gobble up the oxidized or modified LDL while these particles are still circulating in the blood.

How and whether unmodified LDL particles cross the wall of arteries into the “sub-endothelial” area remains an unsolved complex issue. The picture above implies that LDL particles simply move across the endothelial cells that line the wall of the artery but that is a presumption.

Clearly, macrophages that have “swallowed” modified LDL particles have mechanisms to work their way between the junctions formed by adjacent endothelial cells.

This is an important distinction because many cardiologists believe that what drives atherosclerosis is a mass effect. The greater the number of LDL particles, the more likely they are to cross the endothelial barrier, get oxidized and retained and start the process of plaque formation. However the process is much more complex and not clearly understood.

We do not yet know or understand completely the factors that influence the permeability of the endothelium to Lipoprotein particles. We do know that modified (oxidized and glycated LDL) disrupt the protective surface of endothelial cells which is called the glyocalyx. Other factors that disrupt the glyocalyx include high blood sugars, dramatic fluctuations in blood pressure (too high or too low), oxidative stress, infections, and circulating endotoxin (which is governed by intestinal permeability).

It is clear from several studies that modified (oxidized) LDL as a single variable predicts cardiovascular disease and heart attacks with much greater accuracy than LDL-C (total cholesterol content of LDL particles). It is also clear that monocyte receptors are specific for modified LDL and that the  process that initiates the cascade of events that leads to plaque formation involves the interaction between modified lipoprotein particles and the immune system (monocytes).

Now here is another twist.

Omega 3 fatty acids in fish oil are considered “heart healthy”. They help prevent heart attacks and strokes. They also decrease inflammation throughout the body thereby producing many health benefits.

BUT OMEGA 3 FAT HAS MORE DOUBLE BONDS THAN OMEGA 6 FAT (LINOLEIC ACID) YET THEY HELP PROTECT THE HEART. HOW CAN THAT BE?

How do they avoid contributing to atherosclerosis? Are they not even more readily oxidized than linoleic acid?

The simple answer is no.

The major reason is that the omega three fatty acids are protected by “plasmalogens” which are important components of our LDL particle outer membranes. Plasmalogens are found in the membranes of lipoprotein particles and in the membranes of human cells. Because of their chemical structures, omega three fats are easily incorporated into plasmalogens which protect the double bonds of omega three fats from oxidation. Linoleic acid, the predominant component of “vegetable oils” is not easily incorporated into the protective arms of plasmalogens.

This selective protection is well described on pages 141-142 of  “The Fats of Life”, written by Dr. Glen Lawrence and published in paperback in 2013. (link below)

I asked Dr. Lawrence about this issue in an email and here was his response.

“The omega-3 fatty acids are preferentially incorporated into plasmalogens, which act as antioxidants due to the double bond adjacent to the ether linkage of these phospholipids. This structure would tend to scavenge free radicals or reactive oxygen species near the surface of the membrane, rather than allowing them to penetrate deeper in the membrane where the double bonds of PUFA are located. This makes any polyunsaturated fatty acids attached to the plasmalogens more resistant to oxidation than they would be in a regular phospholipid. See pp 141-142 of The Fats of Life. The shorter chain and less unsaturated linoleic acid does not tend to be incorporated into plasmalogens.”

In summary:

  1. “Vegetable oil” is actually not oil from vegetables but rather a highly processed and refined oil. This oil contains primarily the easily oxidized omega 6 PUFA (polyunsaturated fatty acid) linoleic acid. Oxidation can occur during manufacture,  before consumption while sitting in the bottle, but especially during high heat cooking (fried foods). Oxidation can also in your body as this fat circulates in your blood on the membrane of lipoprotein particles.
  2.  LDL particles are the major lipoprotein particles that shuttle cholesterol and fatty acids (in in the form of triglycerides) through our bodies in our bloodstream.
  3. Modified LDL particles (glycated and/or oxidized LDL) stimulate monocytes (immune cells) to transform into macrophages and gobble up the modified LDL. In addition, glycated LDL particles are more easily oxidized because they circulate longer in our blood.
  4. Macrophages become filled with modified LDL. These are called foam cells. Foam cells  initiate a cascade of events that lead to the formation of plaque in the walls of our arteries.
  5. The part of the LDL particle membrane that becomes oxidized is the phospholipid that contains linoleic acid which comes from “vegetable oils”
  6. High amounts of sugar, especially HFCS, and highly refined flour foods in our diets cause larger blood sugar fluctuations than whole foods and therefore contribute to the glycation of LDL particles. This glycation leads to more oxidation of LDL. In this manner HFCS and refined flour foods contribute to the process of atherosclerosis.
  7. High amounts of sugar, HFCS and refined flour foods also contribute to obesity, insulin resistance and diabetes which then increase the risk of heart attack and stroke.
  8. Several factors contribute to the disruption of the glycocalyx which is the protective surface of the endothelial cells that line our arteries. These include but are not limited to modified LDL, inflammation, high blood sugars, abnormal fluctuations in blood pressure, circulating endotoxin (associated with increased intestinal permeability), infections. Disruption of the glycocalyx contributes to the formation of plaque (atherosclerosis).
  9. Modified LDL particles might also migrate through the junctions that connect adjacent endothelial cells either inside macrophages or on their own. Many factors, known and unknown likely determine the susceptibility or permeability of these junctions to this migration.

These are the major points, but there is allot more to discuss. Substituting “vegetable oils” for saturated fat in our diets not only increases the amount of oxidized LDL but also increases a dangerous lipoprotein called Lp(a). On third of Americans have an amount of Lp(a) that is considered “high risk” for heart attack and stroke. More about that in a future post.

Then there is the process of an actual heart attack or stroke which involves disruption of plaque and the creation of a blood clot that ultimately disrupts the flow of blood and the death of heart or brain tissue. The susceptibility of plaque to disruption is a huge topic that involves high blood pressure, diabetes, insulin resistance, oxidative stress, inadequate sleep, and stress to name a few. So much more to discuss.

But getting back to the title of this post, why don’t you ask your elected representatives why our tax dollars continue to subsidize nutritional root causes of death, disability and disease?

Here are some links to papers and books that support the discussion above.

“Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present, the result being that he does not live in the present or the future, he lives as if he is never going to die, and dies having never really lived.”

Stress Reduction and Health

Mindfulness based stress reduction (MBSR) has been demonstrated to have beneficial effects relative to several physiologic measurements in humans. These include improved immune status, decreased inflammation as measured by blood tests, improved DNA repair (increased telomere length), and alterations in metabolic activity in areas of the brain that are viewed as beneficial relative to stress, anxiety and pain as measured by functional MRI scan of the brain (fMRI). Similarly other forms of meditation have been studied relative to cardiovascular risk in humans. The results indicate that stress reduction from meditation can decrease the “composite risk of death, heart attack and stroke” by 48% in patients who have experienced a previous heart attack. (1)

“A selected mind-body intervention, the TM program, significantly reduced risk for mortality, myocardial infarction, and stroke in coronary heart disease patients. These changes were associated with lower blood pressure and psychosocial stress factors. Therefore, this practice may be clinically useful in the secondary prevention of cardiovascular disease.”

This degree of protection exceeds the benefits of statin drugs in patients who have had a heart attack  and exceeds the risk reduction accomplished by cardiac rehabilitation exercise programs.

A review of studies on the effects of meditation on cardiovascular disease reported: (2)

Psychosocial stress is a nontraditional risk factor for cardiovascular morbidity and mortality that may respond to behavioral or psychosocial interventions. …. Randomized controlled trials, meta-analyses, and other controlled studies indicate this meditation technique reduces risk factors and can slow or reverse the progression of pathophysiological changes underlying cardiovascular disease. Studies with this technique have revealed reductions in blood pressure, carotid artery intima-media thickness, myocardial ischemia, left ventricular hypertrophy, mortality, and other relevant outcomes. The magnitudes of these effects compare favorably with those of conventional interventions for secondary prevention

Dr. Dean Ornish utilized both meditation and yoga training in his lifestyle intervention program along with moderate exercise, smoke cessation and elimination of junk food (low fat vegan diet). The results demonstrated reduced coronary artery plaque within 2 years. Although many have attributed this to the vegan low fat diet, I have suggested in the past that the beneficial results were accomplished by stress reduction, exercise, smoke cessation, and elimination of junk food (especially refined sugar, flour, trans-fats and refined vegetable oils)

Our culture is not attuned to the regular practice of meditation or yoga. When I recommend stress reduction with these techniques to my patients few pursue it despite providing them with detailed descriptions of the physical benefits demonstrated by medical studies. One does not need to become a Buddhist in order to benefit from the practice of meditation. In the early 1970s the first stress reduction clinic utilizing MBSR(Mindfulness Based Stress Reduction) and Yoga was established at the University of Massachusetts Medical Center by Jon Kabat Zinn PhD. Since then many studies have documented the benefits of stress reduction relative to cardiovascular disease, diabetes, hypertension, chronic pain management, depression and anxiety.

Patients who have experienced their first major depressive episode can reduce the risk of a subsequent major depressive episode by 50% simply practicing MBSR regularly.

Unlike drugs, angioplasty, coronary stents, surgery, and injections, meditation and yoga have no potential negative side effects or complications. They simply require time, practice and a modest amount of training. Inexpensive self-help books, CDs and on-line resources are available to get started. Measurable physiologic benefits are experienced within a few weeks. Blood pressure drops, stress hormones decrease, blood sugars come down, insulin sensitivity improves, immune cells work better, sleep improves, suffering from chronic pain decreases, and functional status improves. That’s a considerable amount of benefit achieved by simply sitting quietly and observing your breath as it moves in and out of your body.

Meditation and yoga are two ways to reduce stress. For a healthy life to achieve stress reduction we must examine many areas. What aspects of daily life can increase and decrease stress and our physiologic response to stress?

Important factors to consider include social isolation, physical and social contact with friends/family/pets, meaningful work, laughter and humor, time spent outdoors, exercise, proper sleep habits and exposure to natural rather than artificial light. These all play significant roles in governing our stress levels, physiologic response to stress and the attendant changes in health.

Social isolation is harmful while regular contact with family and friends is beneficial. Caring for a pet seems to reduce blood pressure and enhance longevity. Engaging in meaningful work for pay or as a volunteer is essential for health, longevity and happiness. Spending time outdoors regularly and cycling your daily activity with the sun (circadian rhythm normalization) are essential to health and stress reduction. Laughter and social interaction provide healing while rumination over problems causes illness. All of these aspects to healthy living deserve attention but if you are ill, overweight, suffer chronic pain, disability or substance abuse then meditation and yoga can have profoundly beneficial effects. When combined with a Paleolithic diet and adequate restorative sleep, stress reduction techniques provide a powerful healing pathway.

Below is a long list of links to articles related to stress reduction, meditation, and yoga in the areas of chronic pain, cardiovascular disease, cancer, pre-natal care, anxiety disorders, depression, insomnia, smoke cessation, burnout, immune function, inflammation, migraine, blood pressure control, traumatic brain injury and even psoriasis.

Amputations, Gangrene and Carbohydrates

As an anesthesiologist I have spent more than 60,000 hours in the operating room and cared for over 30,000 patients. I often observe the end-results of bad dietary advice. I am referring to the liberal carbohydrate allowance that the American Diabetes Association and other agencies offer diabetics.

Today was a particularly poignant day as I cared for two diabetics who required amputations for complications of diabetes type II. These complications could have likely been avoided if our supermarkets were not stocked with high carb nutritionally deplete “food” AND if the ADA, physicians and nutritionists counseled diabetics to significantly reduce their carbohydrate intake. Instead, the low fat narrative has so predominated our culture, that we have taken our eyes off of the major dietary threats during the past 40 years, excessive carbohydrates and especially refined carbohydrates.

The leading cause of amputations in modern society are the complications of diabetes including peripheral arterial disease (atherosclerosis in the arteries to our limbs) and peripheral neuropathy (loss of sensation in the feet and hands). The combination of these two, or just one alone can lead to non-healing wounds and ulcers in the feet, then chronic infections and ultimately gangrene. Futile efforts to restore circulation to the legs with vascular bypass surgeries or arterial stents usually just briefly delay the inevitable series of amputations that start in the toes and progress up the leg, step by step until only a stump is left above the level once occupied by the knee.

Gangrene is an ugly thing. During the Civil War the major cause was trauma. Today the major cause is diabetes and indirectly, excess carbohydrate consumption.

The visual experience of gangrene results in a visceral reaction, even after more than 30 years of observation. The knowledge that most of these complications could be avoided by simply eating whole fresh foods instead of crap in a bag or crap in a box is frustrating. The human suffering and economic costs (lost wages, disability, medical expenses) are staggering. Diabetes type II is largely a disease of lifestyle. The lifestyle elements involved include poor dietary habits, lack of exercise, inadequate sleep, and stress. All of these contribute and all are modifiable and avoidable.

Type II diabetes is arguably reversible early in the disease process. As it progresses a patient reaches an irreversible point of no return where the pancreas has been exhausted and the insulin producing cells are no longer efficient and effective. Equally important,  the cells in the rest of the body do not respond in a normal fashion to what little insulin is produced. But even at this stage carbohydrate restriction can mitigate complications if only healthy fresh whole-foods are consumed and modest exercise is practiced on a daily basis.

Other complications of diabetes including blindness, painful neuropathy, kidney failure requiring dialysis, heart attack and stroke all are arguably avoidable with a whole foods paleolithic carbohydrate restricted diet and modest amounts of regular exercise.

What a pity, what a shame, what a waste.

Below are some links and research articles to back up my statements.

Peace, health, and harmony.

Weight Gain, Another Reason to Avoid Statins

Published on line two days ago in advance of print publication, a new study demonstrates an association between statin use and increased caloric intake resulting in weight gain. (1)

A brief editorial (Written by Dr. Rita Redberg, on faculty at UCSF and editor of JAMA: INTERNAL MEDICINE). is worth quoting in entirety as it succinctly reviews many criticisms of statin overuse that I have discussed in previous posts here and here.

“There remains much controversy over the risks and benefits of statins for primary prevention. Besides the risks of muscle aches, diabetes, and cognitive dysfunction, I have observed over the years that for many patients, statins provide a false reassurance, as people seem to believe that statins can compensate for poor dietary choices and a sedentary life. In an elegantly performed analysis of NHANES data from 1999 to 2010, Sugiyama and colleagues have documented exactly such behavior. They found that compared with statin nonusers, statin users significantly increased their fat intake and calorie consumption, along with their BMI, in the last decade. This article raises concerns of a potential moral hazard of statin use, in addition to the already known adverse effects. Focusing on cholesterol levels can be distracting from the more beneficial focus on healthy lifestyle to reduce heart disease risk.” (2)

Of course association does not imply causation, but the editorial above suggests a plausible explanation for the relationship.

I have previously discussed how a carbohydrate restricted whole foods diet (here and here) results in superior weight loss, improved glucose control, reduced blood pressure, reduced triglycerides and improved HDL when compared to a low fat American Heart Association type diet. The former results in spontaneous reduction of caloric intake (improved satiety-no calorie counting required), the latter requires calorie counting in order to reduce caloric intake. The carbohydrate restricted approach does NOT result in increased net fat intake but because carbohydrates are reduced, fat as a % of total calories is increased. On average most studies in adults report a spontaneous reduction of about 400-600 calories per day when carbohydrates are significantly restricted.

A paleolithic diet that eliminates all processed foods, refined vegetable oils, grains, legumes and dairy but includes pastured grass-fed meat, wild seafood, free range poultry and eggs, organic fresh vegetables, fruit and nuts is typically low carbohydrate compared to the standard American diet (SAD). A paleolithic nutritional approach produces similar metabolic improvement within a few weeks. (3)
