Dr. Laura: The Science of Eating a Rainbow

The colours that our foods employ are very functional and serve a purpose. Phytonutrients are vast and the last time I counted, there were over 5,000 known.

Allow me to introduce Dr. Deana Minich, MD. She has dedicated her career to express why, in scientific means, we should “eat” a rainbow. In the chart below she simplifies how different coloured foods serve our body.

What makes this even more interesting is that this chart also closely reflects the colours that relate to the energy centres of the body called chakras. This makes eating polyphenol rich foods easy to prescribe!

Eating a variety of vegetables and fruits is critical to good nutrition. Try 6 cups of vegetables a day and 1-3 cups of fruit per day. Choose foods for their vital nutrient function in ways that serve the needs of your body.

Plant Power!

Turns out, mother nature has packed a punch of power in the plant kingdom. Many plants contain one or more of these 5,000 nutritional perks that helps us:

  • Defend against pathogens, parasites, and predators.
  • Protect against chronic disease, including cardiovascular disease, neurodegeneration, and cancer.
  • Purify and renew the blood
  • Nourish
  • Cleanse body of toxins
  • Stimulate effects
  • Relaxing effects
  • Anti-inflammatory

So next time you are in the grocery store, hit the fresh produce aisle and think “Eat a Rainbow”! You just might find the gold that exists at the end of it…your good health.

Dr. Laura: Is Your Thyroid Tired ?

Perhaps your thyroid needs a check-up? It does if you feel sluggish, tired, constipated, have difficult concentration, and are a wee bit depressed.

Subclinical hypothyroidism is when a patient with sluggish digestion, cognition, fatigue and weight issues has a high TSH but normal T4. It is important to look at the reasons for the symptoms, which could have multiple causes, before reaching for the thyroid hormone replacement drug.

Don’t let the sunset on your thyroid…

What nutrients help the thyroid?

Nutrition is a factor. Consider levels of zinc, iodine, selenium and iron as they all play a role in thyroid function. B12 is also an important one to look at and easy to run the labs to determine its status.  Also the health of the gut microbiome and liver needs to be healthy as a large amount of the inactive T4 converts to the active T3 thyroid hormone in the liver and the gut. So many people have issues with the balance in their microbiome.  

Does stress play a role?

Another area of thyroid health to consider is the stress axis. This involves the hypothalamus, pituitary and adrenal, or HPA. Chronic long term stress can make it difficult for optimal thyroid function. In addition to mineral level attention, it is highly important to support the adrenals and provide opportunities for stress management.  

Are there natural thyroid medications?

Finally, there are other options to synthetic thyroid. Natural desiccated thyroid (NDT) may be something to consider if diet and lifestyle changes don’t break through the fog. NDT provides both T4 and T3, which is good if there is an issue with conversion.

How can a naturopathic doctor help?

Naturopathic doctors are medical trained and naturally focussed. They can run labs for the nutrient levels, thyroid stimulating hormone (TSH), T4, T3, and any antibodies to help rule out autoimmune thyroid disease. This helps determine what nutrients might be missing and what foods or nutraceutical dose to suggest and for how long. Naturopathic doctors with education in pharmaceuticals are able to prescribe natural desiccated thyroid. They are also very good at stress management and adrenal (HPA-axis) support with both nutrition, lifestyle and stress management programs.

Dr. Laura: Understand PMS

Premenstrual Syndrome, or PMS can come in a variety of patterns. A whirlwind of emotions, cravings and weight gain often come in tote with the monthly menstrual cycle. Better understand the impacts of the monthly swing in hormones and get the help you need to live a more balanced life.

PMS-A: Anxiety

Anxiety or irritability can come from estrogen excess or progesterone drops. This imbalance in the two major female hormones can make some feel like they want to crawl out of their own skin. Increased levels of estrogen in the second half of the period can allow adrenaline to build up and alter the serotonin balance. Natural treatment includes supportive measures for estrogen clearance, progesterone building herbs, regular moderate exercise, a healthy diet and stress management.

PMS-C: Carbohydrate Craving

Cravings for sweets and refined carbohydrates, feeling hangry, tired or having a headache all fall under the category of PMS-C. Abnormal variations in blood sugar may be a factor of magnesium levels – and this gives into the common cravings for chocolate as dark chocolate is high in magnesium. Noteworthy: a change in serotonin levels can also increase sugar cravings. Therefore, factors in insulin regulation are key and are a focus of treatment. Finally, herbal formulas are also available to reduce the satisfaction of sweets and crush the cravings.

PMS-D: Depression

In addition to anxiety, mood changes throughout the cycle can also lean towards depressive states. Symptoms that suggest the need to modify the stress response include crying, fatigue, headaches, feeling overwhelmed or out of control, and difficulty sleeping. Adaptogenic herbs may be helpful to support the stress response. Chinese formulas and botanical medicine formulas that include nerviness, anxiolytics and antidepressants can be very effective in PMS-D treatment. Certainly, nutraceuticals may also be helpful to modulate levels of serotonin, GABA, and dopamine and thyroid hormone levels should also be monitored, especially if the periods are heavy. Neurotransmitter hormones can be evaluated with take home urine tests called Organic Acid Tests (OATs).

PMS-H: Hyperhydration

Fluid retention is a common PMS complaint. Breast tenderness and distension, bloating, weight gain, swollen hands and feet can all be classified under PMS-H. An increase in circulating aldosterone levels is linked to decreased progesterone and magnesium with increased estrogen. Reduce salt and sodium intake (bread and cheese) and increase sources of potassium (bananas, baked potato with the skin, dandelion leaf tea). Treatment of Liver Qi stagnation with acupuncture and Chinese formulas are often very good at reducing PMS-H.

Naturally Navigate PMS

Naturally navigate your health with Dr. Laura M. Brown, ND

Naturopathic doctors can provide individualized treatment to manage hormones. The whole body is considered, the physical, emotional, cognitive and spiritual. When it comes to hormone balance, the naturopathic tool box is rich. Bring balance to your hormones and bring balance back into your life.

Start your evaluation on your own!

Start your evaluation on your own! Use Clue, the period and ovulation tracker, which is a free Ap for iPhone and Androids. Take note of your diet with the use of aps that help you track dietary, lifestyle and nutritional habits. Bring all this to your first appointment. You may also be a good candidate for a take home urine test. Stress and reproductive hormone can be assessed with an at home urine test, (DUTCH), available and interpreted with your naturopathic doctor.

Dr. Laura: Boost your energy

The energy powerhouses of cells are called mitochondria. These tiny organelles are derived solely from our mother’s DNA and are reposible for generating the energy our bodies need to run.

Mity Mitochondria

  • Make up about 10% of our body weight
  • 200-2000 per body cell
  • relies on the fats, carbohydrates and proteins we eat
  • loves to run on ketones
  • Needs nutrients like calcium, B vitamins, CoQ10, N-Acetyl-Cysteine, Magnesium, Alpha lipoid acid, lysine

Energy Drains

Fatigue comes from drains on the mitochondrial function. This can happen with any type of toxic burden:

  • long term nutrient deficiency
  • poor sleep habits
  • hormonal disruption
  • eating too much in general
  • eating too much sugar
  • excessive exercise
  • heavy metals
  • viruses and spirochetes (Lymes)
  • pesticides
  • plastics, PCB’s
  • drugs
  • mold

Signs of Mitochondrial Dysfunction

Unexplained fatigue, the need for more than 8 hours of sleep on an ongoing basis, poor exercise recovery, impaired sense of smell or taste, headaches, poor motivation, depression, anxiety, brain fog, forgetfulness, extra sensitive to light and noise – are all indicators of poor mitochondrial dysfunction. While other things may be at play like poor thyroid function, hypothalamus, pituitary or adrenal function, it is important to also consider the mitochondria.

Boost Your Energy

Support the mitochondria and reclaim your energy. An initial naturopathic appointment will start the process to understand the source of your energy drain. Together a same day plan could initiate the changes required to boost energy.

Dr. Laura on Potassium Levels

Potassium is a mineral that dissolves in water and carries and electrical charge. Easy to see how it can act as an electrolyte.

Nerve, muscle, and heart function all depend on the appropriate level of potassium.It is absorbed in the small intestine and excreted mostly in the urine, and some in the sweat and stool.

The kidney is the main regulator of potassium levels, so if it is healthy and you are getting regular food sources of it, there likely is no reason to be concerned about the levels of potassium in the body.

Potassium’s role in the body.

  • fluid and electrolyte balance
  • maintains nerve and muscle growth
  • balances pH (acid/base balance)
  • contributes to heart function
  • assists in the use of carbohydrates and proteins
  • interacts with blood pressure
  • supports healthy metabolism and blood sugar regulation.

 

Food sources of potassium

  • acorn squash
  • artichokes
  • bananas
  • citrus
  • dried fruits
  • dark leafy greens
  • dried beans
  • legumes
  • nuts
  • potatoes (white and sweet)
  • soy
  • tomatoes
  • cod
  • salmon

Low levels of potassium

Potassium deficiency, or hypokalemia may be noted by fatigue, weakness, muscle cramps, heart palpitations, cardiac arrhythmia’s, hypertension, and postural hypotension. Trouble is, low potassium looks very much like high potassium, however it is more likely to have low levels

Low serum potassium can be caused by inadequate dietary intake, certain drugs, dialysis, plasmapheresis, increased potassium entry into the cells, decreased potassium exit from cells, and increased losses in the urine, gastrointestinal tract, or sweat.

High levels of potassium

Hyperkalemia rarely produces physical symptoms. Excessive potassium can disturb heart and skeletal muscle function, cause nausea, fatigue, muscle aches and weakness and increased respiratory rate.

Some medications can lead to higher than normal potassium levels:  ACE (angiotensin-converting enzymes), some antibiotics, anticoagulants, ARBS (angiotensin-receptor blockers), beta-blockers, COX-2 inhibitors, cyclosporine, antifungals, NSAIDs (non-steroidal anti-inflammatory drugs- Advil, Motrin), and potassium sparing diuretics.

Fasting, high blood sugar, metabolic acidosis, kidney insufficiency are all contributors to high levels of potassium.

Measuring potassium

Unless there is a state of severe deficiency, it can be difficult to assess proper levels of potassium. Blood serum levels may be normal, while blood cellular levels deficient. Beyond this, levels in the muscles may not reflect either the levels of blood cell or serum.

So long as the kidneys are functioning well and no drugs (as mentioned above) interfere,  there is generally no need to worry about higher intakes of potassium, as it will be sufficiently excreted.

Dr. Laura: 5 ways to strengthen your immune system

Immune system need a boost? Support it with one or a combination of these top five natural ways. A strong immune system means less colds and flu, especially through this winter and early spring season.

As a start, be sure to wash your hands regularly with soap and water keep indoor humidity around 45-50%. Then, visit your naturopathic doctor to find what is the best combination of these five following things you need to strengthen your immune system.

1. Probiotics

2. Adaptogens

3. Medicinal Mushrooms

4. Vitamins

5. Minerals

 

Probiotics

We know that 70% of your immune system resides in the gastrointestinal tract, so it makes perfect sense to keep a healthy balance of your microflora. Research in probiotics is very active and there may be new strains available to help you balance yours.

Adaptogens

The adrenal glands are little hat like glands that sit atop the kidneys.  When you think of cold weather, think of hats and think of adrenal support. Resilience to stress can keep illness at bay but when we are constantly under stress at work, at home and toxins build up from pesticides, environmental factors, drugs, allergens – we need help. There are a number of adaptogenic herbs like holy basil, ashwagandha, ginsengs, liquorice, schisandra, codonopsis, astragalus and rhodiola that can be custom blended to support your needs.

Medicinal Mushrooms

Medicinal mushrooms can be an amazing support for the immune system. Helpful are hot water extracts of mushrooms like maitake (Grifola frondosa), reishi (Gandoderma lucidum), Cordyceps, shitake (Lentinus edodes), turkey tail (Coriolus versicolor), and sun mushroom (Agaricus blazei). It is possible to get these in different combinations and even in packets to make a “tea”.

Vitamins

Vitamin A, C, E top the list for immune support. Oranges, citrus and bell pepper provide Vitamin C.    The beta-carotene in orange and red vegetables will convert to Vitamin A in most people. Cod liver oil is a viable direct source of vitamin A.  Wheat germ oil and almonds pack a punch of vitamin E. There are formulas available that combine these vitamins with some minerals and they can often be a sure way of getting the support you need every day.

Minerals

Zinc, Selenium and Magnesium are truly critical for the immune system to function. A varied diet will often provide enough. Bone soup broths are a great, as are pumpkin seeds for the zinc, brazil nuts for the selenium and dark leafy greens for the magnesium.

Dr. Laura on Detoxification

Detoxification is a continual process. This happens at a cellular level throughout the body especially in the liver, kidney, lungs, skin, gastrointestinal tract and emotions.

Cellular toxins

When a cell encounters a toxin, be it too much sugar or alcohol, pesticides, BPA, lead, mercury, cadmium, arsenic, nickel, chemical flame retardants, phthalates, viruses, bacteria, fungi or parasites it mounts a cell danger response (CDR).  This load triggers a series of protective reactions that slows the transport of   goods across the cellular membrane. The membrane walls thicken just like our ancestors ravaged in war, built their walled cities for protection. This response to cellular danger is a fundamental component of innate immunity and can be helpful in times of distress.

Seasonal influence on detoxification

There comes a time when things must come and go from this walled city.  Seasonal influence provide an important basis for organ focus. For example, in the height of summer, the emotions, digestive and energy movement are most active. Autumn is more a time for the lungs and large intestine.  Winter brings the kidney and bladder centre stage. Finally in spring the liver and gallbladder are most ready to clear out the build up from the cold winter months.

Long term effects of toxic exposure

Long term toxic exposure with little support leads to chronic disease. This is when the cells continually want to keep their walls of protection. This is not healthy. Garbage builds up, and the inward flow of nutrients slow down. We also get this feeling after the long, cold winter months as we have hibernated inside, put the heat on and slowed our movement in and out of the house. It is always interesting what tends to happen at human levels of behaviour are also reflected at levels of cellular behaviour.

With this in mind, it might be proactive to think about more outside activities to keep your cells and energy from becoming too stagnant. The kidneys and urinary bladder are likely more open to accept attention in the winter time.  The urinary bladder is pretty straight forward in its function; eliminating water soluble waste that has been prepared by the supporting organs in the body. The kidneys themselves are responsible for blood filtration, mineral and acid base balance. They decide what gets filtered out and what gets recycled back into the body. In Chinese Medicine, the kidneys include the adrenals, our body’s organs that help us adapt to stress.  It is important through the winter months to also ensure the adrenal glands are well supported.

Near the end of one season and the beginning of another, during equinox, the need for the organs shift. So in late winter, early spring, the stage prepares for the kidneys, adrenals and bladder to fade and the liver and gallbladder begin to take centre stage. If the flow of energy through these organs is not smooth, it generally results in a lack of creativity and feelings of irritability and nagging frustration.

Organ System Screening

Electro dermal screening (EDS) can provide insight into the health of your detoxification organs. Much like an EKG on the heart or EEG on the brain, nervous system conductance related to each organ may be captured at peripheral points of the nervous system on the hands and feet. The onsite EDS equipment at Forward Health is German engineered, precise and needle free. 

Detoxification Plan

Together with sensitive body biofeedback from the EDS equipment and understanding what’s bothering you, Dr. Laura M. Brown, ND can create a clear detoxification plan to help you relax those walls you and your cells have built, and get the river of life flowing smoothly once again.

Dr. Laura: Cough and Cold Relief, Naturally.

Naturopathic medicine offers much in line with cough and cold relief. The common cold and sinusitis are classic respiratory tract illnesses.

Respiratory Tract

The respiratory tract can be affected by many different cold viruses which  cause coughs due to inflammation, pain, and irritating mucous. The typical respiratory virus lasts 7-10 days.

Prevention

  • wash hands
  • avoid cross contamination
  • strengthen immune

First line is prevention. Washing hands regularly with soap and water is key. Also keep unwashed hands away from common sites of viral and bacterial entry: the nose, eyes, ears and mouth. Medicinal mushrooms, herbal formulas geared to the immune system, garlic, vitamin C may all be used to help strengthen the immune system.

Early signs

At early signs of throat tickles or glandular reactions, there are homoepathics and essential oils, mineral and botanical sprays that can nip things before they take off. Wet socks can also be helpful to boost white blood cells.

Naturopathic Treatments for Cough and Cold

Relieve blocked sinuses

There are acupuncture points to help balance heat and cold in the body, as well as ones that activate and release the sinuses. Even a single treatment can provide significant relief. At home hydrotherapy is always useful. A nasal saline rinse, wet socks or steam inhalation can all help you breath and sleep better at night and breathe better through the day. Steam inhalation with essential oils of thyme, lavender or eucalyptus allows antimicrobials to come in direct contact with the respiratory tract mucosa and the heat will help loosen the mucous. Herbal remedies blended to suit the symptoms of the cold and cough are very helpful to reduce the severity and duration. They offer antimicrobial factors, reduce inflammation and soothe irritated tissues. Mucolytics are neutracueticals which help break up mucous. Dr. Laura will work with you to find the best combination of remedies for you.

Relieve cough

  • Herbal remedies to soothe and reduce inflammation of mucous membranes
  • Homeopathic remedies prescribed for the specific nature

As mentioned above, custom blended herbal and homeopathic remedies can reduce the intensity and duration of the respiratory virus. Often, in upper respiratory tract infections, it is the post nasal drip of mucous from the sinuses that produces the cough. In lower respiratory tract infections, there is also irritating mucous involved. In both cases, it is important to treat the mucous congestion as mentioned above and soothe the tissues.

Treat lingering cough

  • Nebulized Glutathione

Nebulized or inhaled glutathione may be helpful to nourish and restore respiratory tract tissue. It is useful in any trauma to respiratory tract including smoke and fume inhalation and treatment can reduce and even avoid the post viral cough. Glutathione offers antioxidant protection and immune support while avoiding influence on plasma levels.

Alterations in the levels of glutathione in the lung and alveoli are widely recognized in many inflammatory lung diseases. Glutathione in the lining fluid of the lower respiratory tract is the first line of defence against oxidative stress.

Dr. Laura: How does your thyroid function?

Feeling tired, loosing hair, bring fog, brittle nails, constipated,  periods heavy and cholesterol rising? Perhaps your thyroid is to blame.

What does thyroid hormone do?

Thyroid hormone keeps:

  • our metabolism humming
  • hair and skin smooth and silky
  • muscles and tendons well lubricated
  • mood bright
  • digestion moving along
  • brain firing on al cylinders
  • LDL cholesterol at healthy levels

How do you measure thyroid function?

General practitioners assess Thyroid Stimulating Hormone (TSH), and if it is out of range, T4 and T3 is measured. Sometimes an ultrasound is done to visualize the size and health of the gland, to assess nodules or help diagnose thyroid cancer.  Naturopathic doctors, functional medicine doctors and endocrinologists will be more likely the ones to run a full thyroid panel (freeT4, freeT3, TSH, TPO, Anti-Thyroglobulin and reverse T3).

How does the body naturally balance thyroid hormone?

T3 is the active hormone in the body and is made from T4. Although the T4 is made in the thyroid, conversion to T3 happens mostly in the liver and the gastrointestinal tract.   A normal functioning thyroid gland works with the hypothalamus in the brain using a negative feedback system to indicate when there is enough active thyroid hormone in the system.

How does the medical doctor balance thyroid?

Traditionally synthroid or levothyroxine is prescribed to treat inadequate levels of thyroid hormone and treatment is geared to reach a desired TSH level. Direct T3 therapy (Cytomel) is rarely prescribed due to lack of research and clinical experience. Typically the family doctor will  treat to normalize the TSH, but recent research, and numerous patient complaints may indicate that this is not enough.

More research is required to support T4 and T3 combination therapy, whether it is levothyroxine plus cytomel or natural desiccated thyroid, alone or in combination.

Research finds TSH monitoring is not enough to determine adequate thyroid functioning and some medical doctors agree a 4:1 ratio of T4:T3 predicts patient satisfaction and better health.

What does the naturopathic doctor do to balance the thyroid?

Naturopathic doctors seek to support the thyroid in making T4 and the body’s ability to convert the T4 to the active form of thyroid known as T3.   A naturopathic doctor offers support to people on pharmaceuticals like synthroid or levothyroxine, and is also able to additionally or solely prescribe advice for nutraceutical  support and natural desiccated thyroid.

A naturopathic doctor will:

  • look at the full thyroid panel
  • adrenal health
  • cholesterol panel
  • sex hormone health
  • the function of the liver
  • health of gastrointestinal tract,
  • nutrient balance of things like selenium, zinc, iron and iodine

How is cholesterol linked to thyroid function?

T3 levels are also inversely linked to LDL Cholesterol. When thyroid levels are low, LDL cellular reception is reduced, leaving more LDL in the blood stream.  Emerging research finds treatment with T4 alone (synthroid, levothyroxine) does not always correct the high levels of cholesterol induced by poor thyroid function. Rising levels of LDL cholesterol in peri-menopausal women with symptoms of fatigue should trigger an investigation into the balance of T4 and T3, not just TSH.

What drives T3 levels down?

  • Body shuttles T3 to reverse T3 in times of starvation and stress
  • Poor feedback function in the hypothalamus
  • Thyroiditis
  • High levels of natural and environmental estrogens
  • Epstein Barr Virus

T3 levels are increasingly challenged as xenoestrogens (environmental contaminants) rise in developed countries.  Peri-menopausal women also experience challenges. This is because estrogen (unopposed by progesterone as ovulation slows down), or estrogen mimickers like xenoestrogens (from plastics, pesticides and insecticides) have the ability to bind up Thyroid Binding Globulin and somehow affect the T4 to T3 conversion ratio. Some research points to Epstein Barr Virus impacting the genome and ultimately the function of the thyroid.
