Does Eating Fish Reduce Cancer Risk?

Most of us are aware by now of the cardiovascular benefits of having fish in the diet.  Eating omega-3-rich fish, like salmon, reduces blood pressure and fat accumulation in the arteries.  The recommendation from Heart associations is to consume at least two portions of oily fish per week.  Is there anything else that is healthy about eating fish?  Apparently there is.

Saint Luke’s Mid America Heart Institute in Kansas City conducted a review in 2014 of

red fish isolated on white background

Italian studies that strongly suggests that eating oily fish twice-per-week can also help to prevent the development of cancers of the breast, colon, intestine and esophagus.  The authors also emphasized the importance of how you prepare the fish for eating.  The low risk of developing the afore-mentioned cancers was only apparent when prepared using olive oil and wasn’t fried or preserved with salt.

This makes you wonder, of course, whether there were other factors involved besides the omega 3 in the fish itself creating the lower cancer risk.  This being said, the benefits of consuming fish are undeniable on the heart and circulation, and lowering the risk of cancer would certainly be a welcome perk.

Walking Is Better For Your Heart Than Running

Good news for all sedentary middle-aged people!  A recent study from the Mayo Medical School in Minnesota analyzed the effect of a three month interval-walking program on peak aerobic capacity (the amount of oxygen consumed per unit of work).  Compared to the non-training group, the training group – over three months – increased their peak aerobic capacity by an average of 28 percent.  The regimen involved five or more sets of three-minute, low-intensity walking alternated with three minutes of high-intensity walking cobblestone street walkfor an average of four days per week.

Running can also be good for you, but, as the scientists at the Lawrence Berkeley National Laboratory in California found out, although running reduced the risk of heart disease by 4.5 percent in individuals between 18 and 80 over a six-year period, walking reduced the risk of heart disease by 9.8 percent (almost double).  So it is safe to say that you “should walk, not run, when you cross the street”.  A walking interval-training program is apparently the way to go…so get going!

Why Should You Work Out In The Morning?

Testosterone burns fat, builds muscle and increases sex drive in men and women.  Testosterone, like most steroid hormones, has a daily rhythm – highest in the morning and decreasing over the day.  It has been suggested that our ability to perform follows the same trend i.e., testosterone levels can predict our physical performance over the day.  A team at Swansea University, lead by Professor Kilduff,  evaluated the effect of training in the morning on testosterone response throughout the day.

Using testosterone levels derived from saliva sampling, 18 semi-professional rugby Morning  exercise and black clockplayers were divided into three groups:  the control or resting group; the sprint group (5 x 40 meters) and weight-training (bench press and squat) group.  A follow-up saliva sample was taken before the players completed a performance test (back squat and bench press, 40m sprint and jump test).

The results showed the circadian decline in testosterone levels was negated by morning training.  In other words, working out (especially with weight training) in the morning  keeps the testosterone levels from dropping during the day and increases performance in power sports at least six hours after the initial workout.

If you recall in a previous blogs (2 and 3), I mentioned the reasons why maintaining testosterone levels is extremely important for men and women.  Here is a short list:  Increases bone density, decreases cholesterol, helps to prevent Alzheimer’s disease and dementia, prevents and treats depression, protects against cardiovascular disease, hypertension, excess body fat and arthritis, enhances memory and cognition, and protects against Diabetes, Insulin Resistance and Metabolic Syndrome.   Perhaps changing how and when we exercise may reduce our tendency to certain health conditions by maintaining optimal steroid hormone levels.

Force of Illness #3: Inflammation & Disease

The “Third Force of Illness” is Inflammation.  The inflammatory process is a natural body reaction to injury, infections, allergens, toxins, pollution, pesticides, food additives, drugs, cosmetics, chemicals, free radicals and oxidative stress.  The five associated signs that the process of inflammation is occurring are redness, swelling, heat, pain and loss of function.  The first three signs are the ones most often associated with inflammation – and we have all experienced it.  It is usually local and self-limited.  The body runs into trouble, however, when inflammation is excessive, chronic or systemic.

As strange as it sounds, the most common externally-generated cause of inflammation isBlue cold gel pack to kill the pain what happens in the digestive tract.  Even though we consider the “gut” is inside, it is actually “outside” us.  If we turned ourselves inside-out, the gut would be on the outside (like the skin).  The gastrointestinal tract is one of our primary defenses against invaders.   In many ways, it is an extension of the skin and similarly protective.  When the gut is inflamed, the inflammation process occurs in other areas of the body – like the covering of the bones and the walls of the arteries.  Any arthritis or arteriosclerosis has at its roots this inflammatory process.  As an interesting side-note, researchers are finding  that certain micro-organisms exist in the wall of diseased arteries.  We may find that cardiovascular disease may be linked to the presence of one or more of these organisms triggering the inflammatory response – just like Helicobacter pylori has been linked to the development of stomach ulcers.

In other words, gut function – especially an “inflamed” gut – affects other systems directly.  The digestive tract is a major regulator of the immune system.  Even though the source of the inflammation may be different, the end result is the same i.e., inflammation activates the immune system systemically.  Whether it starts in your pinky finger or your molar, inflammation puts your immune system on alert.  Reducing inflammation in the gut can, and does, have a modulating effect on the majority of disease processes that have an immune system component.

By far, the most common internally-triggered factors for chronic inflammation are free High resolution 3D human for anatomy,medicine and healthradicals and oxidative stress – which can be caused by anything that depletes the body of “antioxidants” e.g., overeating, obesity, chronic infections, toxins, and so on.  Please understand that free radicals are one of the naturally-occurring by-products of cellular metabolism.  Free radicals are kept from damaging tissue by “antioxidants” which neutralize them.   The problem results from an imbalance between free radical production and free radical neutralization.  Unadulterated colourful vegetables and fruits are perhaps the best way to get your daily dose of antioxidants e.g., vitamins A,D,E, K, C.  There are also certain supplements, like N.A.C., that increase other important antioxidants like glutathione.

Virtually all of us are antioxidant deficient, with inflamed digestive tracts and low-grade chronic inflammation.   This not only puts a heavy burden on the body, but it is my contention that it takes its toll on the Brain/Mind as well.  Much of the anxiety and depression experienced by our young people (which I consider epidemic) is directly related to poor diet and digestion.  An inflamed gut, most definitely can lead to an inflamed mind – and drugs are not the solution.  Mind what you eat, and eat for your mind.  Say “no” to your latte and say “hello” to you morning antioxidant smoothie!

The Second Force of Illness: Impaired Metabolism or Burnout

The First Force of Illness is inadequate digestion and absorption of foods (or “sludging” – as we mentioned in the previous blog) and endothelial dysfunction.  The Second Force of Illness is “burnout” due to impaired metabolic/cellular processes creating an overall lack of energy.  How many of you suffer from being “tired”.    Metabolism is the term used to describe the creation of usable energy from food – and fatigue is an indicator that you may have an impaired metabolic ability to generate this “food energy”. The main factors in impaired metabolism are:  insulin resistance, mitochondrial dysfunction and thyroid dysfunction.

A major player in “burnout” is glucose regulation and control.  There is a saying that you chargercan have “too much of a good thing” – and this applies to carbohydrates – especially glucose and sugars.  Insulin, secreted by the pancreas in response to carbohydrates in the blood, regulates the uptake of glucose into the cells.  In the current North American diet, insulin secretion is virtually constant due to the almost continual intake of sugar and carbohydrates.  The only thing the body can do is to continue to secrete insulin in the attempt to lower the blood sugar level.  The cells can only take in a certain amount of glucose at a time, so the cells, under the stress of too much insulin, will do the logical thing – change the receptors for insulin making them inactive.  The scientific term for this is Insulin Resistance.

When a cell is unresponsive to insulin, our cells become unable to get energy from the food we eat – despite the fact that we have eaten enough – and our insulin blood levels become chronically elevated.   We become tired and hungry.   The cells are crying out for energy and we crave the quickest energy source (sugar) – which only compounds the problem when we eat them.   For our ancestors, food availability was always in question, so the body adapted by being able to store away the energy that we didn’t immediately need in the moment for use later – as fat tissue.  In today’s society, however, food (especially carbohydrates) is plentiful for most of us, so the “rainy day” never comes – but we still eat as if it could.  This is the crux of our obesity epidemic.  .  High insulin levels in the blood and Insulin Resistance have not only been linked to obesity, but also to arteriosclerosis and heart disease, stroke, high blood pressure and diabetes.

Mitochondrial Dysfunction is the second major part of burnout. Mitochondria are the energy producers of the cell.  They do this by taking sugar, fatty acids or amino acids from your food and, in the presence of oxygen, burn them to create energy.  Mitochondrial dysfunction is caused by a number of factors.  Overproduction of free radicals (also known as “reactive oxygen species” or RburnoutOS) can cause mitochondrial damage.  This is why you take antioxidants like vitamin A and E.  Poisoning from heavy metals, petroleum products, pesticides and trans fats also contribute.  At the cellular level, we find mitochondrial damage or dysfunction occurring in almost every type of major illness e.g., heart disease, stroke, diabetes and cancer.

The third major factor in impaired metabolism is thyroid dysfunction.  The thyroid is like the gas pedal in your car and determines your rate of speed.  Too little thyroid hormone and your metabolism slows.  Too much and your metabolism “red-lines”.  A low-functioning thyroid – especially in women – is becoming the norm.  Symptoms of hypothyroid include:  being cold all the time, weight gain, constipation, oily skin, coarse hair, increased cholesterol and depression.  There are many possible causes which include allergic reactions (wheat allergy/celiac disease has a well-known association with autoimmune thyroid disease), toxins, infections, hormonal disturbances and low selenium or iodine levels.

In the next blog, we will explore the ways you can test for “sludge” and “burnout”.  Until then……

Testosterone Is Important To Heart Health: How to Raise It Naturally

In the last blog, I mentioned that my “patient” (myself) was experiencing uncharacteristic fatigue and lack of motivation.  The regular blood tests showed a normally-functioning thyroid, no anemia and blood sugar regulation within normal parameters.  The cholesterol level was slightly high but not significantly changed over the last few years.  The total testosterone was within the “normal” range, but the free or “active” testosterone was in the very low part of the range. Remember what I said about testosterone and heart disease?  The free or “active” form of Testosterone helps to protect a man’s heart and arteries.  Dr. Edward Lichten, M.D. in his “Textbook of Bio-Identical Hormones” states that “scientifically, vitamin D, human growth hormone, thyroxine (T4), and triiodothyronine (T3), DHEA, and testosterone in men and estradiol in women have strong cardio-protective or therapeutic applications”.

Man running in a gym on a treadmill concept for exercising, fitnWhat can a 58-year-old male do to increase his testosterone? Exercise – especially resistance training – tends to increase the testosterone level and the HDL.  Reducing fat mass increasing lean muscle mass also reduces the tendency of the body to convert testosterone to estrogen and decreases insulin resistance.  It is important for a man’s reproductive health that his body have the correct levels of Zinc, Vitamin E, and certain amino acids (like L-Citrulline and L-Arginine) vitamin C, B vitamins, and magnesium.  Certain herbs are reputed to raise the free testosterone level – in particular, Tribulus terrestris and Eurycoma longifolia.  Taking the natural precursors to testosterone production may increase levels e.g., DHEA, if it is available.  Reducing stress is very important because high levels of cortisol (produced when stressed) suppresses DHEA.   In general, I prefer patients to raise their testosterone levels through natural stimulation – rather than immediate testosterone replacement – if at all possible.  Read on as I make testosterone stimulation very personal….

In my case, Blood Spot testing (done by finger prick and is a combination of arterial and venous blood) had previously been done in 2012 and was repeated on the same day as the regular blood tests last month.  In 2012, the only parameter that was slightly below normal was the Testosterone level.  The current test showed a further 30% drop in testosterone and a 56.5% reduction in DHEAS values.  The current results show that there are four cardiovascular parameters that are now abnormal:  the triglycerides are elevated (20% more than 2012); the HDL or good cholesterol has decreased by 40%; the VLDL (the very bad LDL cholesterol) is elevated as is the insulin level.  In addition, the Vitamin D level is also severely low – which is surprising because I routinely take 2000 IU per day.

In a nutshell, it is my contention that most, if not all, of these cardiovascular-related changes are due to a less-than-optimal testosterone and vitamin D level .  Unless I take appropriate action, I will become insulin-resistant (Type 2 diabetic) and the mechanisms of arteriosclerosis will continue to increase.  Rather than immediately going for Bio-identical testosterone replacement, I will attempt to raise the testosterone level through exercise, stress reduction, weight reduction, nutrient supplementation and so on over the next few months and will report back to you when the tests are repeated in January 2015.
