Eat for Life: Time Restricted Eating

What if there was one simple lifestyle change that could increase your lifespan? Researchers who study the science of longevity and disease prevention have found that there is indeed one simple lifestyle pattern that can decrease the risk of cancer, heart disease, obesity, diabetes and more: don’t eat at night. It turns out that our bodies are designed to process food better during the day, and when we eat at night, we rob our cells and organs of much-needed rest and repair. Studies show that while of course it matters what we eat, it also matters when we eat.

The human body evolved to eat during the daylight hours, when it’s safe to collect and prepare our food, and not to eat in the evening, when it’s dark and dangerous to be outside. Fifteen percent of the human genome works on a body clock, and about 50% of those genes are involved in the metabolism of food. We know the brain has a circadian rhythm, but so do the pancreas, intestines, liver and more.

Now with the advent of electricity and demanding work hours, we typically have our largest meal of the day in the evening and often snack after that. Our meal patterns are not in alignment with how we evolved to eat and can be detrimental to our metabolism and our cellular repair mechanisms. Does it really make sense to consume most of our calories within hours of going to sleep? It’s like showing up to a restaurant at closing time: the cooking staff will not be happy. Eating at night has been shown to raise blood sugar and insulin, increase inflammation, throw off hormones and decrease the important daily cellular clean-out called autophagy. Under these conditions the body can become fertile soil for disease.

As a naturopathic physician I regularly monitor these blood parameters and show people ways to lower their risk factors with lifestyle changes and natural medicines. One of those ways is to just change when you eat. Eating breakfast, lunch and dinner within the daytime hours, before 7 p.m., and allowing at least a 13-hour fast overnight is enough to show benefits. Some experts recommend extending that fasting window further by having a later breakfast and an earlier dinner if you can.

Time restricted eating has even been shown to reduce cancer rates. In one study, of 2,500 breast cancer survivors who tracked their food intake for seven years, a strong association was found to when they were eating. Women who had at least a 13-hour overnight fast had a 40% decrease in breast cancer recurrence and an over 15% decrease in all causes of mortality, regardless of whether they were overweight or not.

Other conditions that have been shown to improve from extended overnight fasting are gastric reflux, fatty liver, cardiovascular disease and diabetes. Weight loss with this mechanism alone is modest, but it can add up over time. In a famous study, two groups of mice were fed the same number of calories, but one group was fed only during the mice’s daytime and the other could graze all day and night. The mice in the Time Restricted Feeding group lost more weight than the other mice. In similar human trials, weight loss is more significant because without even trying, people will consume about 200 fewer calories per day when they stop nighttime snacking.

Time Restricted Eating is a simple lifestyle change that anyone can implement. Your body is designed to thrive in those conditions. Pregnant women and people with blood sugar issues, eating disorders or other health conditions would be wise to consult with their naturopathic physician or family doctor before making any dietary changes.

Finding Calm within the Storm

Life is full of twist and turns, good days and bad days, change and uncertainty. These are the things we cannot change. What we can change is how we deal with all the ups and downs of life. We can face our fears and work through them as best we can. We can call upon our highest thinking, and bring forth our deepest strength.  We can have hope that out of struggles, new and better ways of being will be discovered. As a naturopathic physician, I have studied psychology, various therapeutic modalities, attitudinal healing, a number of spiritual practices, and watched how thousands of my patients have risen to the challenges in their lives. From this experience, I offer you a seven step system for facing the difficult emotions of life. May it help you to navigate the storms of life to find a place of greater calm.

Step One: Pause and observe your mind and body. Just noticing your thoughts, feelings and body sensations in a curious way is the first step. Gently observe with non-judgmental inquiry. Just stopping, stepping back, and noticing that this train of thoughts and feelings is causing you stress allows you to separate from the process a little bit so you can look at it and question it. 

Step Two: Breathe. Bringing your mind’s focus to your breath helps to calm both the body and mind.  It’s amazing how just a few deep breaths can begin to shift fear, anger, anxiety and more. You may wish to try breathing in through the nose and out through the mouth, or even add a small sigh on the outbreath. Imagine the stress flowing out as your exhale. Feel your shoulders drop and feel your weight settle into your pelvis, legs and feet to help “ground” you. Apps like Insight Timer and Calm provide guided relaxation and breathing exercises to follow.

Step Three: Name the feeling. Often we get overwhelmed and just feel “stressed” in general. Here I invite you to be curious about what you are feeling in particular.  Is it grief, anxiety about the future, anger at someone, powerlessness, or fear of rejection? Try and mine down to what’s really going on and put a label to that particular pattern of body sensations, thoughts and feelings. Just naming and acknowledging the feeling is a step towards acceptance. And in the naming, we are again stepping back from the feeling to a place where we can work with it. 

Step Four: Self Compassion. Here is where we give ourselves the kindness and understanding that we often seek from outside ourselves. Dr. Kirsten Neff describes Self-Compassion Practice well in her TED talk, website and online guided exercises. You might say to yourself, “yes, of course you are feeling nervous about your health; how human is that? It’s so understandable.” Or you might say “how hard it is to feel so much uncertainty about the future or to adapt to so much change….” By leaning into the feelings instead of rejecting them, we are in a place to practice being with our feelings instead of wanting to escape, blame others, or act out in reflexive ways. 

When we are stressed and running on adrenalin, the survival part of the brain is activated and the frontal cortex, where more creative problem solving can be accessed, is shut down. We tend to react in patterns we developed as children: fight, flight, freeze or fawn.  The first four steps of this system are designed to calm the nervous system, balance the brain, and prepare us to move from reactivity to more helpful, resourceful ways of being.

Step Five: Question the thoughts that drive the feelings. Consider the possibility that behind every feeling is a thought. By identifying the thought, we can start to question it, and reframe it from a more adult, realistic, and resourceful mindset. Cognitive Behavioural Therapy (CBT) is the world’s most researched and successful therapy technique and it is a set of tools for dealing with life stresses in a better way. The website anxietycanada.com is an excellent way to learn about CBT and how it can help you deal better with day to day life. I love the list of questions under the section “Challenging Negative Thinking”, such as “Is this a hassle or a horror?”, “Am I confusing a possibility with a certainty?”, “Have I confused a thought with a fact?” and more.

Step Six: Affirm your strength.  A lot of anxiety is really a fear that you don’t have what it takes to deal with adversity: rejection, pain, death, humiliation, grief, change, etc. I invite you to think of examples of when you have been strong in the face of adversity before, and think of what you drew on in yourself. Or think of others who have found strength in times of trouble: people you know, your ancestors, or people around the world. By affirming your strength you can let go of trying to plan for every possible bad thing and how you would deal with it. You can simply trust that you will have the inner strength to face each challenge as it comes. You can focus more on the moment with self-talk like “Right here, right now, I am okay and I can deal with this moment”, “I am wise and strong”, “I am the source of the love and security I seek”. 

Step Seven: Let go and trust. It is often said that stress is the difference between expectations and reality. The outside world will always be full of challenges and changes. I humbly invite you to be open to the possibility that just maybe some meaning will come from these experience. Great growth rarely happens without great struggle.

These seven steps can be done in one minute or in a two-hour journaling session. They can be done alone or with a trusted person. You can reach out to me for a naturopathic consultation or to another counsellor. The more each of us can commit to staying grounded emotionally the more we can help uplift others. May you find your calm within the storm.

Buyer Beware of Chemicals in Your Home

There are an estimated 84,000 different chemicals in our environment and 700 new ones are released every year.  The majority of these have never been tested for safety.  Chemicals that are tested are done in isolation, yet in the real world are bodies are bombarded by hundreds of chemicals and it is the total toxic burden that overwhelms our body’s natural defences. These chemicals enter our bodies every day through food, water, air, health and beauty aids, furniture, clothing and more. Scientific evidence is pointing to chemical exposures as major contributors to cancer, reproductive problems, early puberty, autoimmune disease, Autism, Alzheimer’s disease, Parkinson’s disease and other neurological and metabolic disruptions.



Our bodies have not yet evolved the mechanisms to defend against the assault of modern chemicals. I had a patient who was a very tough military veteran.  He had survived the unimaginable and was quite psychologically resilient.  But the mosquito coils that he slept with for years in while posted in Germany emitted a potent neurotoxin intended to paralyze mosquitos.  Unfortunately the mosquito coils also poisoned his nervous system and was the likely cause of the rare neuro-muscular disorder he developed, and eventually succumbed to. As tough as he was as a person, his physical systems had never evolved the mechanisms to withstand these toxins.
Canadians spend 90% of their time inside, which means we spend most of our daily lives exposed to chemicals found in common household items and dust. We all have of toxins stored in our body and are passing them to our children. Babies are being born with chemicals in their system.  In a US study, there were an average of 287 chemicals detected in umbilical cord blood, 217 of which are toxic to the brain and nervous system.  At Simon Fraser University, research showed that those babies whose mother’s had the highest concentration of chemicals had a lower IQ at age five.



Some chemical exposure is beyond our control, but we can choose which chemicals are entering our homes through the products we buy. Environmental Defence, a Canadian organization that promotes environmental health, has created a list of the chemicals in consumer products that cause the worst damage to human health. These “Toxic Ten” include flame retardants, parabens, phthalates, petrolatum, silicone (the latter four are commonly found in over the counter skin and hair care products), and perfluorinated compounds (PFC, PFAS – found in water resistant products such as Scotchguard, Gore-tex, Teflon, raincoats, food wrappers, and microwave popcorn bags).



According to Health Canada, flame retardants are found in many consumer products including foam in mattresses, pillows and stuffed toys, in fabrics such as  clothing, tents, rugs, and upholstery, and other products like computers, plastics, paint, foam used in construction, glues and more. Health Canada states that the health effects of these chemicals may include effects on development, reproduction and increased risk of cancer. Research has shown that they are hormone disruptors, can alter thyroid function in pregnant women, and can cause neurodevelopmental problems in children (such as lowered IQ, Autism, and ADHD).



Parabens can easily be absorbed through the skin and are commonly found in lipstick and other make-up, skin care products and deodorant.  Parabens are strong estrogen mimickers, androgen (male hormone) disruptors, blockers of detoxifying agents in the body, and more. For instance, they are known to disrupt five out of the seven mechanisms cells use to protect themselves from breast cancer.
BPA’s are found in plastic food and water containers, tin / soda can lining, cash register receipts and more.  They are known hormone and immune system disruptors, and the newer BPA substitutes may be just as bad.  Consumers have demanded the reduction of BPA’s in food packaging and are buying metal water bottles instead of drinking from plastic water bottles.  Educated consumer using their buying power will be what moves our society from a toxic soup to a cleaner world.



These household toxins combine to create an unprecedented toxic burden to our bodies, and I haven’t even gotten started talking about pesticides in foods, chemicals in medicines, and the toxins we knowingly ingest in artificial sweeteners, cigarettes, alcohol and drugs. They all adds up.  But you can make a difference. Knowledge is power.



Naturopathic doctors help their patients to prevent and address disease by engaging them in strategies to remove stresses on the body, including the build-up of chemical toxins.  We can test you for toxic burden (“CORE” by Genova Diagnostics) and support you in a program to detoxify your home and your body. Next month we’ll talk about steps you can take to reduce your exposure to toxins in your home. Also check out the Toxic Ten Pocket Guide at environmentaldefence.ca.

Hope for Parkinson's Disease

Muhammad Ali and Michael J. Fox are famous people who have Parkinson’s disease, and one in 500 people in Canada will join their ranks. Parkinson’s disease (PD) is a degenerative neurological disease that slowly affects the ability to control movement.  Symptoms can include tremors, difficulty walking and speaking.  Early symptoms can include decreased thirst, loss of smell, constipation, anxiety and decreased arm swinging while walking. This condition was thought to be chronic and progressive and could only be managed with medications.  Now, with a deeper understanding of the factors that contribute to nerve cell damage, there are targeted strategies that can slow or even reverse the disease to some degree. Many of these principles are just smart preventative lifestyle strategies for all of us who want to protect our brains from degeneration.



Dr. Laurie Mischley is a naturopathic doctor who works with people with Parkinson’s disease in Seattle.  The average Parkinson’s patient has a symptom score of 500 at the time of diagnosis in a standardized test for Parkinson’s, and their score goes up by 38 points per year on average.  In contrast, Dr. Mischley’s patients have an average 200-300 point decrease in their score over one year of treatment.  Those numbers got my attention when she spoke at a recent brain health conference I attended.



Dr. Mischley is emphatic that Parkinson’s does not have to be a progressive, irreversible disease.  Progression can be slowed and sometimes reversed to a degree if we seek to understand what is stressing the neurons and remove those stresses while supporting optimal brain health with targeted lifestyle strategies and natural medicines.  Dr. Mischley says that by the time PD is diagnosed, the processes that created it have been in the works for twenty years or more.  Science has shown us that risk factors include drinking well water with high manganese or pesticide runoff, head trauma, heavy metal exposure (welders), dairy consumption, pesticide exposure, certain viral or fungal infections, intestinal microbiome imbalances, autoimmune processes, high iron, low B12, smoking, drinking and more.  If we can identify and target these neurological stress factors, we can improve brain health.



Lab tests can help us identify the stress factors associated with Parkinson’s disease.  These include inflammatory markers (CRP), blood sugar work up, iron, vitamin B12, food allergies, heavy metal testing, intestinal testing, brain auto-antibody testing, vitamin D, oxidative stress tests, (low) cholesterol, homocysteine, DHEA-S, thyroid function and more. Naturopathic physicians can order these types of lab tests and provide thorough analysis.



Dietary interventions include eating more plant-based foods, such as fruit, vegetables, nuts and seeds and healthy oils.  Fish and organic chicken are encouraged, while dairy, red meat, flour and sugar are discouraged. Exercise can play an important role in Parkinson’s treatment, and our local recreation centres are providing classes specifically for this condition. Natural medicines are also vital for creating an environment in the brain where the nerves can thrive. Coenzyme Q10 and fish oil are associated with better outcomes in PD.  Glutathione precursors provide protection against oxidative stress in the brain, which is critical for PD.  Targeting heavy metal elimination, autoimmune balancing, gut microbiome restoration, mitochondrial repair, and homocysteine-lowering are the types of individualized treatments on which naturopathic physicians can coach their patients.  Medications that promote dopamine are an important aspect of the management of PD, but knowing that you can also address the causative factors and take charge of the progression of this condition is empowering.

Understanding Food Allergies and Sensitivities

Have you noticed that more and more people are avoiding certain foods for health reasons?  It turns out that food allergies and intolerances are more common than we once thought. Identifying and eliminating food allergies can solve a broad range of health problems.  I have had hundreds of patients find that once they learn to eat a diet free of their triggering foods, they can get off prescription medications and enjoy much better health.  It turns out good scientific studies are backing up this treatment method.

The symptoms of food allergies can be obvious, such as when people have anaphylactic reactions to peanuts or shellfish.  These food allergies are usually easy to identify.  Other allergic reactions are much subtler and can be delayed, making it challenging to figure out which foods are causing symptoms.  For instance, acid reflux is commonly aggravated by eating certain foods, but the reaction may come the next day.  I have had many patients who determine that dairy causes their sinus congestion, but it may take two days for their sinus headache to set in.  Therefore, to identify most food allergies, careful testing and dietary experiments are necessary.  Food reactions can range from fatigue, depression, post nasal drip, ear infections, constipation, diarrhea, skin issues, headaches, joint pain and more.  In my twenty years of naturopathic medical practice, I have found that helping people eliminate food allergies has been one of the most successful interventions that we can make to help people feel better with less medication.   I am happy that medical science is confirming my clinical experience in several studies on food allergies.

Children who get ear infections often have food allergies that cause excess mucous in their middle ear, setting them up for infection.  A clinical study showed that 94% of ear infection prone children who avoided their food allergies had fewer ear infections.

Many factors can cause migraine headaches, and food allergies can be one of them.  In a study of chronic migraine sufferers who avoided food allergies, 85% became headache free.  In another study, patients with rheumatoid arthritis who avoided food triggers fared much better than the placebo group who ate normally.  In a follow-up study 10 years later, of the 100 rheumatoid arthritis patients who avoided food allergies, one-third were still well on a food allergy free diet alone, without medication, which is remarkable.

Irritable bowel syndrome is a condition I see frequently and know it to respond well to naturopathic treatments, including food allergy elimination.  In a study published in the Lancet medical journal, 14 out of the 21 patients with IBS who went on a hypoallergenic diet for one week became symptom-free.

Celiac disease is a special type of food intolerance where the immune system not only reacts to gluten, but it can send out anti-bodies that affect healthy tissue, like the intestinal lining, the brain, the thyroid and more.  Screening for this food reaction is available through an MD or an ND through blood testing, and a diagnosis can be confirmed by a biopsy taken by a specialist.  Anyone with digestive issues should be tested, but so should people with autoimmune, neurologic and psychiatric conditions. For people with Celiac disease, avoiding gluten containing food, such as wheat, can be life changing.  While true Celiac disease is uncommon, more people have non-celiac gluten intolerance or a simple wheat intolerance.  These people also fare better off wheat and / or gluten containing foods.

While it may take some careful testing and experimenting to figure out which foods are contributing to a health issue, it is certainly worth the additional effort.  When I coach my patients on how to avoid their food allergies and enjoy healthy alternatives, they are often thrilled that something so simple can make such a difference to their wellbeing.

Healing Concussion and Traumatic Brain Injury

The human brain is a remarkable feat of engineering.  But with the consistency of Jello, it is quite vulnerable to damage from injuries.  Every year about 200,000 Canadians suffer concussions.  Sports injuries and car accidents are two common causes of brain injuries, but for seniors, concussions are more likely to be caused by a fall.  The good news is that the brain can recover from minor concussions within a short time. But for multiple concussions or more traumatic brain injuries, the path to recovery can be long and winding.  Post-concussion syndrome can persist for years without the proper help.  Research is showing that there are many ways to enhance healing of the brain. No matter how long it’s been since the brain injury, it’s never too late to jump-start more repair of those delicate structures of the brain that run our mind and body.

Concussions are difficult to diagnose with imagine like an MRI or CT scan, and the symptoms of post-concussion syndrome can be easily attributed to other things.  I often ask my patients about concussions and sometimes find that they do indeed have symptoms of post-concussion syndrome such as:  fatigue, memory loss, cognitive issues, headache, depression, anxiety, irritability, sleep issues, sensitivity to light or sound, issues with sight or hearing, nausea, dizziness and more.

The best approach after a brain injury is to minimize the damage and promote brain healing as soon as possible.  To do that, we have to understand how the brain cells actually get damaged with brain injury.  Then we can use treatments that target those processes. Most medical professionals are not versed in strategies to address what’s really going on in concussion and brain injury, and so these processes are left to damage the brain especially in the critical first few days after concussion.  We need to institute neuroprotection strategies that promote healing, and it’s never too late to start.

Neural inflammation is a significant cause of loss of brain cells, and the connections between them, after head injury.  There are a number of natural products that help to regulate neural inflammation such as curcumin, the DHA portion of fish oil, and green tea. Aerobic exercise also has tremendous benefits to the brain.

We also want to decrease oxidative stress on the brain cells by ingesting higher amounts of anti-oxidant rich foods and medicines.  Berries are rich in antioxidants and Vitamins C and E can be helpful too.

The blood brain barrier (BBB) is intended to only allow certain things to enter the brain from the blood, but after brain injury, there can be a breach in this filtering system.  Toxins then can enter the brain and cause more damage.  Alpha lipoic acid is excellent for healing the BBB and is also an antioxidant.

Mitochondria are the furnaces of the cells, producing needed energy.  The brain cells are particularly dependent on mitochondria for energy. Brain injury can damage the mitochondria and especially lead to brain fog and fatigue.  To heal from brain injury, we need to ramp up the mitochondrial function by taking supplements such as coenzyme Q10, B vitamins as well as eating whole foods and exercising.

We want to stimulate that parts of the brain that can regenerate by enhancing neural stem cells. Humble nutrients like Vitamin D and melatonin can help accomplish these goals.

Promote the lymphatic drainage in the brain called glymphatics. Like a Zamboni clearing the effects of ice skating on an ice rink, the glymphatics of the brain clear away the normal waste products that build up in the brain daily.  This is even more important post brain injury. Sleep is the time when these mechanisms ramp up the most, so I help my concussion patients enhance their sleep.
The nerves of the brain are intimately linked to the chemistry of the digestive system.  Chemicals produced by the gut bugs, or intestinal microbiome, travel to the brain and influence mood, thinking and more.  Having a healthy digestive system will help brain function and naturopathic physicians are an excellent resource for tools to enhance gut health.

Other treatments for concussion are also getting much needed attention.

Brain training can help make new connections in the brain.

The ketogenic diet, while somewhat arduous, has been shown to help a number of brain diseases, including post-concussion syndrome.

Neurofeedback is a sort of visual gym for learning to retrain and re-pattern disrupted brain activity (and is available in Comox).

Functional Neurology practitioners can help target the part of the brain that is malfunctioning and provide specific stimulation to heal those parts.

Cold laser therapy to the skull has demonstrated benefits to many patients at a Toronto clinic and human clinical trials are underway.  This painless treatment has been shown in animal studies to enhance brain healing after traumatic brain injury.  I have treated over 1000 people for various health issues with laser therapy as it helps to gently but quickly regenerate damaged tissue throughout the body.

Reducing electromagnetic fields that may not affect people with healthy brains, but may be one more stress on an injured brain. Turning off wireless at night and removing cordless phones from the bedroom are a good way to start.

There is hope.  No matter how far out from a brain injury, there is always reason for hope.  With the right treatment, people can improve significantly even years after a brain injury if they are willing to invest in their brain health.

Bladder Infections in the Age of Antibiotic Resistance

Remember the days when you would go to the doctor and get an antibiotic for every sniffle and cough? Those days are over because overuse and overreliance on antibiotics have created bacteria which can no longer be killed by ordinary antibiotics.  Doctors are now rightly conflicted because the antibiotics they prescribe may kill most of the bacteria but leave the few that are resistant and allow those strains to proliferate.  Multiple antibiotic resistant strains of bacteria cause infections in one in 16 people admitted to hospitals in Canada and cost $250 million per year. The Public Health Agency of Canada estimates that by 2050, there will be 10 million deaths annually worldwide caused by antibiotic-resistant bacteria, overtaking diabetes and cancer combined. 

In my decades of  practicing as a naturopathic physician, I have seen an increasing rate of these tough infections in my patients.  In particular, I have seen many women, particularly older women, who’ve had multiple bladder infections in a year, and some even need to use very strong intravenous antibiotics to treat them. The naturopathic approach to treating recurrent UTIs goes beyond just killing the superficial bacteria.  It endeavors to change the environment that is allowing the bacteria to persist.  It is a multi-faceted approach that is an example of how naturopathic medicine can play a role in reducing antibiotic resistance by stopping these types of tough bugs in their tracks. 

UTIs are generally created by bacteria from the feces migrating up the urethra and taking hold in the bladder.  In tough recurrent cases, biofilms can form that harbor infection.  Biofilms are a slimy goop that protects the bacterial community from antibiotics and the body’s natural defenses. For my patients with recurrent UTIs, the first step is to make sure they understand how to practice good hygiene.  Then I teach them how to check their own urine at home with a dip stick that can show signs of infection.  I use herbs that help to reduce the adherence of the bacteria to the bladder wall.  These herbs essentially flush out the bacteria, unlike antibiotics which are trying to kill them. Thus, the bacteria don’t mutate to avoid the herbs the same way.  I also use antibacterial herbs to reduce the population.  Plus we look at ways to break down the biofilm to allow greater access to the bacteria.  Scientific studies have shown that there are herbs that can do just that.  For my older patients, we look at strengthening the tissues of the urethral opening by introducing a bit of estrogen locally.  Repeated antibiotic use in the past has usually disturbed the natural defences provided by the good bacteria in the body.  Studies show that oral use of certain probiotics bolsters the genital good bacteria colonies, which can then act as the first line of defense against migrating nasty bacteria and reduce the incidence of UTIs as effectively as daily use of an antibiotic. I also look at ways to enhance the immune system with lifestyle and natural medicines, so the body’s natural defences are in fighting shape.  This type of whole-body approach can be very successful at stopping the cycle of infection and thus reduces the use of antibiotics.  We all need to do our part to turn the tide on antibiotic resistance

Preventing Illness while Travelling

Even though we live in one of the most beautiful parts of the world, many people from the Comox Valley travel abroad for business or pleasure.  Part of preventative medicine is planning ahead for a safe trip and making good choices while overseas.  How far you need to go to ensure a healthy travels depends a lot on where you are going of course.  For travel in North America and Western Europe, some common sense is all you need. Pack a first aid kit, make sure you have adequate travel medical insurance, and practice good street smarts.  Taking a self defense course is a wise move for travelers, as criminals often lurk in highly touristy areas and count on tourists having their guard down.



If you are travelling further abroad to developing countries, the Centre for Disease Control and Prevention has a website where you can learn which immunizations are recommended or required for the areas you’ll be visiting.  Travel medical clinics are also a great source of information.  Updating your basic immunizations may not be a bad idea especially if you are travelling to areas where the population may be under-vaccinated.



Preventing food and water borne disease is important if you don’t want to spend your holiday on the toilet or worse.  People on stomach acid blocking medication for acid reflux or other stomach issues are especially prone to these types of infections because stomach acid is the first line of defense against ingested bugs.  Working with a naturopathic physician to find alternatives to acid blocking

 medications may be a wise choice if you want to stay healthy while travelling.  Taking probiotics prior to a vacation can also bolter your body’s defenses against food and water borne illness.   I encourage my patients to pick up some electrolyte powder and I write them a prescription for antibiotics ahead of time to tuck into their suitcase just in case they get a nasty case of traveler’s diarrhea.



Mosquitoes can be much more than just an annoyance as they can transmit disease.  There are at least 17 known mosquito borne infections including Lyme disease, Zika, Malaria, and Dengue Fever. It is a good idea to pay attention to whether or not mosquitoes are known to live in the areas where you’ll be travelling. Try to cover up and use insect repellents.  DEET is well known, but Picardin has some advantages.  You can even invest in special clothing that has insect repellent infused in the fabric.  Local work wear stores may carry these clothes.  Choosing air conditioned accommodation can help too.  Where malaria is a risk, there are medications that can be taken to prevent the disease from taking hold.



Sometimes people forget to pack their common sense when travelling abroad.  Remember to practice hand washing, safe sex, and street smarts.  The number one cause of death while travelling is motor vehicle accidents.  Mopeds are especially dangerous and some travel health insurance won’t cover injuries related to mopeds.  With a little prevention and travel savvy, you can enjoy your amazing adventures abroad and come home with great stories instead of ill health.

Every year about 200,000 Canadians suffer concussions.  Sports injuries and car accidents are two common causes of brain injuries, but for seniors, falls are a common cause.  The good news is that the brain can usually recover from minor concussions within a short time. But for multiple concussions or more traumatic brain injuries, the path to recovery can be long and winding.  Post-concussion syndrome can persist for years without the proper help.  Research is showing that there are many ways to enhance healing of the brain. No matter how long it’s been since a brain injury, it’s never too late to jump-start more repair of those delicate structures of the brain that run our mind and body.



The symptoms of post-concussion syndrome can include fatigue, memory loss, cognitive issues, headache, depression, anxiety, irritability, sleep issues, sensitivity to light or sound, issues with sight or hearing, nausea, dizziness and more.



The best approach after a brain injury is to minimize the damage and promote brain healing as soon as possible.  To do that, we have to understand how the brain cells actually get damaged with brain injury.   Then we can use treatments that target those processes. We need to institute neuroprotection strategies that promote healing, and it’s never too late to start.



There are about seven known mechanisms we can target to help heal a damaged brain.  Neural inflammation is a significant cause of loss of brain cells after head injury.  Oxidative stress on the brain cells damages delicate structures. The blood brain barrier (BBB) is intended to only allow certain things to enter the brain from the blood, but after brain injury, there can be a breach in this filtering system.  Toxins then can enter the brain and cause more damage.  Mitochondria are the furnaces of the nerve cells, producing needed energy.  After brain injury, the mitochondria can’t supply as much energy to the neurons. The brain’s natural healing may be compromised, so we want to stimulate the parts of the brain that can regenerate by enhancing neural stem cells. We need to promote the lymphatic drainage to clear away the normal waste products that build up in the brain daily.  The brain is intimately linked to the digestive system.  Having a healthy digestive system will help brain function.  Naturopathic physicians are trained in methods to address each of these seven mechanisms to enhance brain healing after concussion.



Other treatments for concussion are also getting much needed attention.  Brain training can help make new connections in the brain.  Neurofeedback is a sort of visual gym for learning to retrain and re-pattern disrupted brain activity (and is available in Comox). Functional Neurology practitioners can help target the part of the brain that is malfunctioning and provide specific stimulation to heal those parts.  Cold laser therapy to the skull has demonstrated benefits to many patients at a Toronto research clinic and human clinical trials are underway.  This painless treatment has been shown in animal studies to enhance brain healing after traumatic brain injury.


No matter how far out from a brain injury, there is always reason for hope.  With the right treatment, people can improve significantly even years after a brain injury if they are willing to invest in their brain health.
