I would encourage everyone to watch this series of daily interviews and discussions on lifestyle and brain health. This was organized and produced by Mark Hyman MD, director of the Functional Medicine Clinic at Cleveland Clinic, well known author, speaker and physician, Discussions cover many topics including environmental toxins (such as heavy metals and Roundup), nutrition, exercise, sleep, stress reduction, gut bacteria, and more with specific reference to the effects on your brain and risk for dreaded conditions such as Alzheimer’s and other forms of dementia, Parkinson’s disease, multiple sclerosis, etc. These conditions can be prevented and when present, they can be treated with interventions not usually employed by modern medicine, unless you are fortunate enough to be working with a Functional Medicine practitioner.
You can sign up to receive a daily email with a link to the on-line video. Each video in the series is available for 24 hours starting at 3 PM PST, 6 PM EST.

Ever wonder why the public is so confused about nutrition recommendations? Just follow the money and you will understand that most of the professional societies that publish nutrition articles are funded by big food companies that are trying to sell more sugar, refined carbs and junk food. I recently read an excellent post about this topic here:
This theme is repeated by medical journals that are “The Official Journal of the Society of >>>>>>” Just fill in the blanks for just about any medical society. Funding comes from big pharmaceutical companies the same way that funding in the nutrition Journals comes from large (junk) “food” manufacturers.
Don’t get me wrong, there are plenty of very valuable, life-saving drugs out there.
But most chronic human disease in developed societies is generated by various combinations of poor nutrition, lack of exercise, disruption of circadian rhythm, inadequate restorative sleep, stress and lack of social support systems.
The obesity and diabetes epidemics continue to worsen yet the failed dietary advise of major health organizations is slow to respond to the data. Excess refined carbs (especially in the form of “food” made with flour) and added sugar (especially in the form of HFCS) are the major driving forces for obesity, diabetes and cardiovascular disease. Red meat is not the culprit, provided the meat is properly sourced (hormone and antibiotic free, grass fed) and cooked in a manner that does not create carcinogens and inflammatory mediators (cook with slow, low, moist heat, high temperature grilling and smoking cause problems, but that topic is for another post).
Americans consume an average 130 pounds per year of added sugar and 140 pounds per year of refined flour. Those are averages so there are many people who consume more. The added sugar is not the white stuff people put in their coffee. It comes in all sorts of forms but is found in energy drinks, soda, lattes and mochas, salad dressing, ketchup, canned soups, canned vegetables, white AND whole grain breads, pasta (even “whole grain”), crackers, breakfast cereal, just about any packaged food that has more than one ingredient on the label. These foods represent 70% of the American diet. The problems created by this situation are enormous and will bankrupt our “healthcare system”. This is a cultural and economic problem.
The solutions are simple but largely ignored in our society. We are creatures of habit and convenience.
Eat whole foods, nothing from a package that has more than one ingredient. Eat meat, seafood, poultry, fresh organic vegetables (6-9 servings per day), fresh organic fruits, and nuts. Meat should be hormone and antibiotic free (free range, grass fed). Seafood should be wild. Poultry should be free range and the eggs should come from free range chickens, ducks, geese.
Do not worry about eating fat as long as it comes from healthy animals and sources such as coconut oil, extra-virgin olive oil, avocado oil and clarified butter (ghee).
Do not use any “vegetable” oils (corn, soy, and other oils from grains or seeds) The vegetable oils are highly refined and inflammatory. They contain easily oxidized omega 6 fats that feed the production of inflammatory mediators in your body and create oxidized LDL leading to atherosclerosis.
Exercise daily, preferably outside in a green space. Twice per week spend 20-30 minutes doing resistance training (lift weights, work against the resistance of bands, use your own body weight doing pushups, pull-ups etc)
Reduce stress with mediation, yoga, tai chi, dancing, engaging in fun sports and social activities. Walk on the beach, by a lake, river or stream, in the woods, listen to music.
Get some sunshine regularly especially during the morning to get your circadian rhythm in order and to produce adequate amounts of vitamin D.
Spend time with family, friends and colleagues who are supportive and fun to be around.
Sleep in the dark.
Get at least 7 hours of sleep per night. Avoid TV, computer screens and other electronic devices for at least 2 hours before bedtime.
Unplug from the internet, email, etc on a regular basis.
We evolved as hunter-gatherers.

I have discussed the effects of nutrition, stress-reduction, sleep, and circadian rhythm on pain in previous posts . I have not yet discussed the theory of how chronic pain develops and persists. This post discusses some of the mechanisms involved in chronic pain as well as therapeutic approaches that have proven to be effective in addressing the root causes of chronic pain and suffering.
THE CENTRAL NERVOUS SYSTEM (BRAIN AND SPINAL CORD) CAN INDEPENDENTLY CAUSE PAIN AND OTHER PHYSICAL SYMPTOMS THROUGH THE DEVELOPMENT OF LEARNED NERVE PATHWAYS. THESE PATHWAYS INCLUDE CIRCUITS WITHIN THE BRAIN AND CIRCUITS CONNECTING THE SPINAL CORD TO VARIOUS PARTS OF THE BRAIN. THEY CAN PRODUCE PAIN EVEN IN THE ABSENCE OF ONGOING TISSUE DAMAGE.
THESE LEARNED NERVE PATHWAYS CAN DEVELOP AS A RESULT OF SEVERAL WEEKS OR MONTHS OF CONTINUOUS PAIN CAUSED BY AN INJURY OR DEGENERATIVE-INFLAMMATORY DISEASE. IF WE EXPERIENCE RELENTLESS PAINFUL IMPULSES COURSING THROUGH THE BODY THESE BOMBARD THE SPINAL CORD AND BRAIN WITH PAINFUL MESSAGES AND OUR BRAIN AND SPINAL CORD EXPERIENCE A CHANGE SIMILAR TO THE CHANGES THAT CAN OCCUR WITH PTSD CAUSED BY ONE OR MORE TRAUMATIC EVENTS.
THESE LEARNED NERVOUS SYSTEM PATHWAYS REPRESENT “NEUROPLASTICITY” MEANING CHANGES IN THE NERVOUS SYSTEM BROUGHT ABOUT BY EVENTS SUCH AS TRAUMA AND STRESS. THEY REPRESENT A “MEMORY” OF THE PAIN, TRAUMA AND STRESS IMPRINTED ON THE NERVOUS SYSTEM. THIS “MEMORY” INCLUDES NEWLY (AND OFTEN PERMANENTLY) FORMED CIRCUITS THAT OFTEN CONNECT VARIOUS PARTS OF THE BRAIN ASSOCIATED WITH PAIN, ANXIETY, DEPRESSION AND ANGER TO PARTS OF THE BRAIN AND SPINAL CORD THAT MEDIATE SENSATIONS OF LIGHT TOUCH AND PRESSURE. THESE CONNECTIONS PRODUCE “ALLODYNIA” WHICH IS A PAINFUL RESPONSE TO A STIMULUS WHICH IS USUALLY NOT PAINFUL. WE CAN ALSO EXPERIENCE “HYPERALGESIA” WHICH IS AN EXAGGERATED PAIN EXPERIENCE, OUT OF PROPORTION TO THE PAINFUL STIMULUS.
THE NERVOUS SYSTEM HAS A BUILT IN “MUFFLER” DESIGNED TO DAMPEN DOWN PAIN MESSAGES BUT IN CHRONIC PAIN THIS MUFFLER BECOMES AN AMPLIFIER THAT NOT ONLY AMPLIFIES THE TRANSMISSION OF PAIN BUT ALSO CONNECTS THIS AMPLIFIED PAIN SYSTEM TO PARTS OF THE BRAIN ASSOCIATED WITH ANXIETY, ANGER, AND DEPRESSION.
ONCE THESE CIRCUITS OR PATHWAYS ARE IN PLACE (“LEARNED”) THEY CAN NOT BE ELIMINATED (“UNLEARNED”). EFFECTIVE PAIN REDUCTION REQUIRES ACTIVATING ON A REGULAR BASIS ALTERNATIVE PATHWAYS THAT ALREADY EXIST SUCH AS THOSE ASSOCIATED WITH PLAY, MUSIC, DANCE, HUMOR, LAUGHING. ACTIVATING OTHER PATHWAYS CAN ALLOW THE PAIN PATHWAYS TO BE “TURNED OFF” OR MUFFLED. AS CHILDREN WE LEARN TO PLAY AND THOSE LEARNED PATHWAYS STAY WITH US FOR LIFE. WITH PRACTICE WE CAN REGULARLY ACTIVATE THOSE BRAIN PATHWAYS AND MAKE THEM AND OTHER PATHWAYS THE PREDOMINANT PATHWAYS OF OUR BRAIN ACTIVITY.
BUT BEFORE WE CAN UTILIZE THE PLEASANT ALREADY-LEARNED PATHWAYS IN THE BRAIN TO CIRCUMVENT THE PAINFUL-ANXIOUS PATHWAYS WE MUST FIRST DEAL WITH OUR ANGER. DEALING WITH OUR NATURAL AND JUSTIFIABLE ANGER REQUIRES FORGIVENESS. UNTIL THE ANGER IS RELEASED AND FORGIVENESS ACHIEVED WE CANNOT MAKE USE OF THE THERAPIES AND STRATEGIES AVAILABLE TO DECREASE AND MANAGE OUR PAIN. ANGER BLOCKS THE PATH TO HEALING AND PAIN REDUCTION.
The brain processes an emotional insult in exactly the same way that the brain processes a physical insult. Stressful life events and our emotional reactions to them may cause pain that is severe. This is why chronic pain becomes worse when we experience a stressful event. Vicious cycles develop as multiple circuits connecting pain pathways to areas of the brain associated with anxiety and depression become activated and stay activated.
COGNITIVE BEHAVIORAL THERAPY: Over the course of months and years, our reaction to chronic pain often includes repetitive negative thoughts. Cognitive behavioral therapy helps us learn techniques to avoid repetitive negative thoughts.
Mindfulness Based Stress Reduction is another technique that can help mitigate the suffering associated with pain. Mindful Meditation practiced 30 minutes per day produces measurable changes in brain activity that can be seen on Functional MRI scans of the brain within 90 days. These changes demonstrate decreased brain activity in areas associated with pain, depression, anxiety and anger. Scientific studies have also demonstrated that MBSR produces improved immune function, reduces blood pressure, reduces heart rate, improves sleep and provides other beneficial physiologic changes associated with healing and wellness. Yoga and meditation are essential components of an MBSR program.
SLEEP: Pain cannot be managed or successfully treated unless an individual gets 8-9 hours of restorative sleep per night. Sleep hygiene recommendations are an essential part of the path to wellness. Daily exposure to sunlight outdoors and restoring normal circadian rhythm are essential for pain management. Going to bed at the same time every evening and sticking to a regular schedule is the most important part of improving sleep. Daytime exposure to sunlight and dimming the lights in the evening are also required. Regular exercise (daily walking) is essential. Wearing blue-light blocking glasses for 2-3 hours before bedtime can facilitate sleep. When blue light wavelengths (light bulbs, computer screens, TV screens) hit the retina of the eye a message is immediately relayed to the “internal clock” of the brain that tells the brain there is still daylight. This inhibits the production of melatonin (the “sleep hormone”). Avoiding bright light (especially from TV or computer screens) for 2-3 hours before bedtime is important. If you must watch TV or work on the computer in the evening that blue light blocking glasses or goggles are a must. There are free software programs that will eliminate the blue light from your computer screen as an alternative to blue light blockers.
NUTRITION: Pain involves inflammatory pathways. An anti-inflammatory diet is essential for treating pain and providing the nutritional components necessary for healing tissue and establishing better brain chemistry. A Paleo Diet removes potential sources of inflammation from the diet. If a patient suffers from an auto-immune disorder the more restrictive Autoimmune Protocol version of the Paleo-diet can help put the disease into remission and decrease the inflammation associated with the auto-immune process.
OBESITY AND OVERWEIGHT: Extra fat around the belly and internal organs causes chronic inflammation throughout the body. The fat cells around internal organs and the immune cells that reside alongside the fat cells both produce a steady stream of chemicals that circulate throughout the body stimulating inflammation everywhere. These circulating chemicals are called cytokines and chemokines. Certain cytokines and chemokines cause fatigue, brain fog, and sensitize the nerves, increasing pain. They also interfere with sleep. Weight loss is an essential component to pain reduction for overweight and obese patients. The best nutritional approach to weight loss includes a Paleo Diet with carbohydrate restriction (low carbohydrate, high-healthy-fat whole food diet). Adding medically supervised intermittent fasting (such as an 18- 24 hour fast every 1-2 weeks, consuming only water for 18-24 hours) can also be effective especially combined with a carbohydrate restricted Paleo Diet and lifestyle.
Exercise and Physical Conditioning: Chronic pain causes sedentary behavior which results in physical de-conditioning. This process involves loss of muscle, decreased bone density, shortening of ligaments and tendons and shrinkage of the tissues that envelope muscle. This leads to more pain when physical activity is increased and a vicious cycle is created. This cycle must be broken with a graduated daily exercise and physical conditioning program. If you follow a medically prescribed exercise program you will not damage your body even though it may be painful during the first several days. Exercise also helps to convert the “amplifier” back to a “muffler” in the nervous system.

At age 46 I had a total hip arthroplasty (THA). Metal and plastic components replaced my hip joint (the stem, ball and socket of the hip). I am convinced that if I had adopted a Paleo lifestyle at age twenty instead of age 58 I would have not needed that surgery. But more about that another time.
On Monday I underwent a revision of that surgery to replace some components, scrape out bad bone, remove inflamed joint lining, flush out plastic debris, and place some bone grafts into areas where bone cysts had formed. The surgery was necessary because the plastic debris from my first artificial joint had stimulated my immune system in a way that caused my macrophages (white blood cells) and osteoclasts (a special kind of bone cell) to start destroying the bone around my hip socket. This process is called osteolysis.
Our immune cells evolved to destroy and consume bacteria and viruses, not plastic powder. So as the plastic liner of my hip prosthesis wore down, the plastic debris provided a constant source of inflammation, stimulating my immune system to get rid of a foreign invader. The bone around my prosthesis got caught in friendly fire. This problem does not seem to occur since a newer form of plastic, having only 10% the wear rate of the old plastic has been introduced. Time will tell if that proves to be true.
To prepare for surgery I reviewed my Paleo behavior with respect to diet, sleep, exercise, stress reduction and outdoor time. My exercise routine was already very reasonable. I had been strictly avoiding grains (except for occasional white rice) and legumes but did include some fermented dairy (kefir and cheese) and wine. So I eliminated all dairy and all alcohol. Sleep has always been an issue because as a physician I take call and sometimes work through the night with emergency cases.
My last call night was 3 weeks before surgery and I was up all night. The next day I flew to NJ for two important events (a reunion and a wedding) both of which were definitely not Paleo environments. A flight cancelation required more sleep deprivation in order to reach my first event on time. That sleep deprivation in combination with the changes in time zone disrupted my circadian rhythm so upon returning home two weeks before surgery I knew I had to play catch-up to be ready for surgery. I avoided alcohol except for a few drinks at my brother’s wedding and violated the wheat prohibition once with a piece of wedding cake.
When I returned to California I was 6 pounds heavier and jet lagged. I promptly got an upper respiratory infection (probably acquired on my flight home) which started in my throat and nose and went to my lungs.
So now I am jet-lagged and infected just two weeks from surgery. Not a good situation.
Thereafter I was strictly Paleo in diet, sleep, and stress reduction (yoga and meditation) but had to limit exercise to yoga and walking in order to fight the infection and prepare for surgery. I spent as much time walking outdoors as was feasible and focused on eight hours sleep each night. After one week I was beating the URI so I decided to do two 30 minute sessions of resistance training during the last week before surgery.
By the day of surgery the URI was completely cleared and I was down 6 pounds to my baseline.
I self administered my own pre-operative medication protocol (designed to mitigate post operative pain) and received a spinal anesthetic from my friend and colleague using a combination of local anesthetic and a small dose of spinal morphine. The latter can provide pain reduction for up to 24 hours after surgery.
So here is the amazing result.
5 hours after surgery I walked without pain using a walker bearing full weight on the surgical leg. I walked again that evening without pain. I knew this was the honeymoon period because the spinal morphine was still protecting me.
The next morning the honeymoon was over but I was still able to walk with full weight bearing without any pain medications and subsequently walked several times up and down the hospital halls during the first three post operative days. Although I had pain with movement I had no pain at rest.
On the day after surgery my CRP (C reactive protein) was 0.2 mg/dl. CRP is a measure of inflammation in the body. Normal range is zero to 0.5. I was elated. One day after a major traumatic event which typically initiates an inflammatory cascade, I did not have excess inflammation throughout my body as measured by CRP. My WBC (white blood cell count) was also normal.
A paleo lifestyle will not prevent pain after surgery but being in a low inflammatory state before surgery certainly helped with recovery.
My walking ability immediately after surgery and during the next three days astounded the physical therapists and nurses. They all stated I had set records.
My colleagues in the Anesthesia Department could not believe that I received no opiate or NSAID pain medications during my recovery. It is now five days since surgery. I have taken no opiate pain killers or NSAIDs except for low dose aspirin (starting yesterday) to help prevent blood clots
I avoided NSAIDs because NSAIDs increase intestinal permeability (which leads to an inflammatory response) and also because NSAIDs increase risk of cardiovascular events (heart attack, stroke, blood clots in the legs which can travel to the lungs and cause death in severe cases)
I can attribute my success to many factors including an excellent anesthetic, a great surgeon, an optimal pre-operative medication protocol, the superb nursing and therapy staffs and the Paleo lifestyle. In preparing for surgery I was able to make an effective come back from a stressful travel week, two successive nights of sleep deprivation and an upper respiratory infection only because of the Paleo approach.
As I walked my laps around the orthopedic unit I noticed that most patients spent the entire day in bed except for a few laps each day with PT. Many factors contribute to that problem. Our PT department is very aggressive but post operative pain, obesity, inflammatory diets and sedentary lifestyles all contribute to slow recovery. The hospital menu is highly inflammatory thick with processed-carbohydrates, pro-inflammatory grains, legumes, and refined vegetable oils, and yes, even some trans fats. A strictly Paleo menu would be very helpful. But most of those patients have been living the Standard American Lifestyle (inflammatory diet, chronic sleep deprivation, inadequate exercise, poor stress management, etc.) for a lifetime prior to surgery and it can take months to years of a Paleo lifestyle to mitigate a lifetime of self abuse. Even then some damage is permanent (like my hip).
I ate the hospital’s fresh fruit, vegetables and wild seafood, the rest was delivered from home by my loving spouse. Kathie is my anchor in the storm and my guiding light when I become lost. The importance of love and human physical contact is well recognized by the Paleo community so it is appropriate that I end with an expression of gratitude to Kathie and the host of friends who visited me during recovery. Hugs and kisses are as important as an anti-inflammatory diet.
Live clean and prosper.

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.
