Seventy-five percent of Americans report they’re exposed to moderate or high levels of it. We encounter it nearly everywhere: in the office, at home, in traffic—even (maybe especially?) at school drop-off. And it can be toxic.

It’s stress.

Skyrocketing stress levels seem like a symptom of modern living. But the body’s stress response is actually quite old, rooted in a time when stressors tended to be life-threatening. Today, our stressors tend to be less serious. (No matter how harrowing your commute feels, you’re probably not spotting a saber-toothed tiger on the B train.) But the stress response, once triggered, is much the same.

And what a response it is. During a stressful event, an incredible sequence of hormonal, cardiovascular and other physiological changes occurs. Heart rate increases (you know that thudding sensation in your chest). Blood pressure elevates and energy stores are made available (the classic “fight or flight” mode). In the short term, this can be a good thing: it can help you nail that interview or deliver an extra compelling presentation. And—just like in ancient times—it can even ensure your survival when you’re faced with a serious threat.

But what happens if stressors keep popping up and those changes happen in the body over and over?

Stress that lasts for prolonged periods (aka chronic stress) can lead to diabetes, major depression and low immune function. And your heart can really pay the price.

How your heart is affected depends on many factors, including your sex. In one study, men showed more changes in blood pressure and heart rate in response to stress, while women exhibited decreased blood flow to the heart and an increase in the beginnings of blood clot formation.

Other research shows ongoing strife and failure to resolve negative emotions may lead to arrhythmias (irregular heartbeats) and even accelerate atherosclerosis (hardening and narrowing of arteries). And that’s just the beginning.

What stress can do to your heart

Increased blood pressure & higher risk of stroke

When the heart is exposed to elevated stress hormones like epinephrine for long periods, damage to the arteries and blood vessels can occur, along with increases in blood pressure and heart rate, as well as a higher risk of heart attack or stroke.

In one study of civil servants, those who believed stress impacted their health “a lot or extremely” had double the risk of heart attack compared to those who believed it didn’t.

Emotionally triggered cardiac events

Emotional triggers have been shown to precipitate cardiac events. The underlying source of stress can vary.

Grief

The risk of experiencing cardiovascular incidents may increase in the months following the death of a spouse.

Anxiety

Chronic work-related stresses like high demands or low salary can pose a two- to three-fold higher risk of cardiac events.

Anger

There is a higher rate of cardiovascular events in the two hours following angry outbursts.

Broken heart syndrome

A broken heart isn’t just a figure of speech. The intense grief or anger experienced by those suffering from heartbreak can cause a release of stress hormones that stuns the heart and impedes blood flow to the body, leading to “broken heart syndrome.” The hallmark of this condition is the heart assuming a bulging, balloon-like shape, and it can cause symptoms similar to a heart attack. But unlike a heart attack, broken heart syndrome is temporary with no evidence of blocked coronary arteries. A quick and full recovery usually follows.

What you can do about your stress

You can put the brakes on stress by tapping into your body’s relaxation response. Here’s how.

Breathe

Try meditation, yoga, tai chi or breathing exercises. Mindfulness allows you to experience calmness, focus, clarity and general mental well-being.

Sweat

Do some form of daily exercise. This releases mood-elevating endorphins and helps to “work off steam” when you’re feeling agitated or angry.

Eat

Eat more fruits and vegetables. The higher levels of vitamin C in citrus fruits and leafy greens help lower blood pressure and cortisol, a stress hormone.

Avoid

Avoid heart-harming behaviors like smoking, physical inactivity and alcohol consumption.

Discuss

Build a strong network of family and friends. Discussing problems and expressing feelings reduces conflict and the stress associated with it.

Enjoy

Make time for enjoyable activities daily. A lower perceived level of life enjoyment has been linked with higher risks of cardiovascular disease incidence and mortality, particularly in men.

Adapt

Botanical medicines categorized as “adaptogens” have been shown to improve the body’s response to and recovery from stress.

Eleuthero is one such adaptogen, with evidence pointing to its ability to help the body accommodate adverse physical conditions and improve mental performance.

Ashwagandha is a favorite adaptogen from the Ayurvedic tradition. In preliminary research, it has shown anti-stress effects.

Rhodiola rosea may improve physical performance and mitigate mental fatigue. Win-win.

Consult your health care practitioner before taking supplements to ensure they are right for you.

Canada now has more adults over 65 than it does children under 15. It’s never too early to learn how to age positively.

People are living longer, and living well. The face of aging in Canada is changing dramatically as life expectancy increases, with an average increase of five years between 1990 and 2012, according to World Health Organization statistics.

With the ongoing pursuit of knowledge to slow down the biological clock, several new insights have helped uncover the science behind aging and its related diseases, unlocking an array of exciting antiaging strategies.

What do free radicals have to do with it?

The secrets of true antiaging lie in the health of our cells. Several vital cellular elements are involved in aging that determine lifespan and longevity. Among the various theories put forth to explain the phenomenon of aging, the “free radical theory” has gained the most acceptance.

Free radicals damage cellular components and DNA, resulting in altered and compromised cell function. This process is continuous and increases with age, causing oxidative damage to tissues that leads to inflammation.

This cellular inflammation and dysfunction has been linked with cardiovascular diseases, cancer, diabetes, and neurological diseases. Antioxidants are said to deactivate or quench free radicals to neutralize them before they attack cells.

Recent research has shown that oxidative stress causes mutations in DNA, which further perpetuate a decline in cellular energy, and an ongoing production of free radicals. Natural antioxidants are proving to be powerful warriors in the fight against cellular aging.

What do telomeres have to do with it?

Telomere length is another intriguing concept that contributes to cellular health. A telomere is a repeating sequence of DNA that forms a protective cap at the end of a chromosome, much like the tags at the end of shoelaces.

Telomeres play a critical role in maintaining the integrity and stability of the genome, and telomere length is a unique marker of biological age. As each cell divides and replicates, the telomeres shorten. This process continues until the telomere runs out, rendering a poor state of cell health that eventually brings about dysfunction and cell death.

Cardiovascular morbidities, neurological disorders such as Alzheimer’s or Parkinson’s disease, and some cancers have been associated, in studies, with telomere shortening; this is further accelerated by oxidative stress and free-radical damage.

Nutrients that combat aging

Science is now revealing the remarkable capacity of certain nutrients to slow down biological aging, restore optimal cell health, and protect and promote telomere lengthening. Embrace healthy aging by incorporating the following 10 age-defying nutrients into your diet.

Omega-3 fatty acids

Multiple studies have shown the cardioprotective benefits associated with high intakes of marine omega-3 fatty acids. They exert lipid-lowering effects, reduce blood pressure, and resolve inflammation.

In a study of 608 cardiovascular patients followed over a five-year period, those with the highest intakes of DHA/EPA (docosahexaenoic acid/eicosapentaenoic acid) had the slowest rate of telomere shortening. Omega-3 fats may also play a role in activating telomerase, the enzyme responsible for reversing telomere shortening.

A recent clinical trial with 71 diabetic women showed that omega-3 fatty acids lower serum glycosylated hemoglobin levels (HbA1c)—the standard test for monitoring glucose control. The findings also showed an increase in antioxidant capacity, which reduces diabetic complications.

Resveratrol

Famous for its role in the so-called French paradox (French wine drinkers with a low incidence of heart disease despite a high-fat diet), resveratrol is a polyphenol found in grapes, other berries, and peanuts. Its mighty antioxidant activity not only scavenges free radicals, but also enhances the production of another powerful antioxidant, glutathione, which is said to facilitate detoxification.

A major constituent of red wine, resveratrol enhances pancreatic function and improves insulin sensitivity in lab studies. Its anti-inflammatory activity may also have applications as a topical cream to treat aging skin.

Turmeric

Curcumin, the most active constituent of turmeric, a herb used in spicy Indian cuisine, has been extensively studied for its benefits in fighting cancer and in relieving pain and inflammation associated with arthritis. In particular, curcumin enhances immune activity and protects brain mitochondria against oxidative stress and amyloid plaque formation associated with Alzheimer’s disease.

Coenzyme Q10 (CoQ10)

This antioxidant is vital for several functions in the body and is ubiquitous (used by every cell). CoQ10 is involved in producing cellular energy and protects mitochondria from damage. Its use in improving vascular function in heart disease is well known.

Its relevance in the health of hair provides a novel use for this nutrient due to its positive effects on the mature hair follicle. CoQ10 stimulates the production of hair keratin, which is an essential component for strong and healthy hair.

Alpha-lipoic acid (ALA)

ALA displays strong antioxidant activity, improves blood flow to nerves, and increases glucose uptake in cells, making it an effective antidiabetic agent. Several clinical trials have shown its use as an effective vasodilator for hypertensive individuals, with promising results in improving cardiac function and reducing atherosclerotic burden.

Vitamin D

In a study of 2,100 female twins, those with the highest vitamin D levels had the longest telomeres compared to those with low intakes and associated shorter telomeres. Declining vitamin D levels are also correlated with higher inflammatory markers—a double whammy that increases the risk for developing autoimmune diseases such as rheumatoid arthritis and multiple sclerosis.

The good news is that adequate vitamin D levels inhibit inflammation, thereby offering protection from many diseases.

Astragalus

Widely used as a qi-invigorating herb in Chinese medicine to alleviate fatigue and weakness, astragalus is also known for its antiviral actions. A compound using astragalus as a prime active ingredient has been shown in lab tests to boost the production of telomerase in cells, which allows dividing cells to replace lost bits of DNA, and even restore healthy cell division.

Folic acid

Telomere length is also influenced by processes called DNA integrity and methylation; both involve folate, and this association has been reported in men and women. Chronic stress is also linked to a lack of adequate methylation, which affects mood and energy, while low serotonin levels and depression also correlate with folate deficiency.

Low folate levels also lead to elevated homocysteine levels, which contribute to heart disease and Alzheimer’s. Supplement with folic acid if your folate levels are low.

Vitamin K

Most people aren’t getting enough of this nutrient, which is found in green leafy vegetables and natto (fermented Japanese soybeans). Vitamin K is known for its role in blood clotting, and studies are pointing out its significance in decreasing bone loss and fracture risk among postmenopausal women.

Calcification of arteries leading to cardiovascular disease and formation of varicose veins are also linked to inadequate vitamin K levels. New research is now illuminating the protective effects of this vitamin in prostate cancer.

L-taurine

Interleukin-6 (IL-6), an inflammatory cytokine strongly associated with age-related loss of strength and muscle mass, is exacerbated with free-radical formation, leading to joint pain. Exercise decreases inflammation, but for older individuals the ability to recover from exercise can be challenging, enhancing the inflammatory cascade. Taurine is an amino acid that acts as a powerful anti-inflammatory and reduces IL-6 production to enable proper recovery and sufficient energy for those who enjoy being active.

When you feel like you’re drowning in a bottomless sea of deadlines, expectations, and long to-do lists, do you reach for more caffeine or sugar-laden snacks to give you a lift? Read on to find much more effective solutions.

Do you feel like you’re drowning in a bottomless sea of deadlines, expectations, and long to-do lists? Are low energy and fatigue common complaints? And are you susceptible to negative moods including irritability or frustration under stress?

Temporary solutions

You should know that what you think will be the gratifying promise of energy from that mid-afternoon candy bar or third cup of coffee is really only a temporary solution to lagging energy or low mood.

Over time, excess caffeine and sugar-laden snacks coupled with stress and a sedentary lifestyle brew up the perfect storm, resulting in a cycle of fatigue, nutrient imbalances, and poor stress response.

Stress can be good

Stress affects everyone and is an inescapable part of life. The susceptibility to stress varies from person to person, as does the response to stress. Short bursts of stress to overcome lethargy or to enhance performance constitute a positive and healthy stress response.

Hans Selye, one of the pioneers of the modern study of stress, referred to this as “eustress,” describing it as a positive force to enhance adaptation mechanisms to stress, as well as to alert the body to make necessary lifestyle changes. This action-stimulating stress gives a hockey player the competitive edge or enables a singer to project enthusiastically, creating a sense of mastery and accomplishment.

Stress can be bad

On the flip side, stress is perceived as a negative experience when it fatigues the body, causes behavioural and physical problems, and contributes to chronic disease. This state of “distress” can produce overreaction, confusion, poor concentration, and anxiety. Neurons in the brain generally “talk” to each other, but during sustained stress over time, these neuronal processes are halted, affecting memory, ability to learn, and the stress response.

Physiologically, human beings are designed to respond to short-term emergencies. The “fight or flight” response initiated by the adrenal glands mobilizes adrenalin and cortisol to release blood sugar and increases blood pressure and heart rate for better oxygen perfusion to the muscles.

Once the crisis is over, the body activates immune responses and calming neurotransmitters to recover from the stress. Harmful effects occur when the stress response system remains in the “on position” chronically, leading to a host of stress-related diseases. Traffic jams, marital strife, financial woes, and other stressors can create an imbalance in homeostasis, the state in which the body maintains a particular balanced physiology.

Interestingly, for cognitively sophisticated humans, the stress-response can also be activated simply by thinking about a stressful situation. Based purely on anticipation, it’s possible to turn on a stress response as robust as if the event had actually occurred! Anticipatory stress can result in anxiety, paranoia, and even depression.

Understanding the physiology of ongoing stress

When stress is prolonged, the adrenal glands eventually become exhausted and depleted, and adrenal fatigue results. The excess cortisol that is released strains body parts and weakens the immune system, which can then cause blood sugar imbalances, insulin resistance, mood and sleep disturbances, chronic fatigue, high blood pressure, diabetes, frequent colds or infection, and weight gain.

Ongoing or excessive stress responses can eventually manifest as autoimmune disease, peptic ulcers, cardiovascular disease, or even cancer.

Workplace stress: increasing global concern

This physiological model of stress holds true in the modern workplace, where multiple pressures to perform, economic upheaval, layoffs, downsizing, pay cuts, and increased workloads along with job dissatisfaction or lack of support are all major sources of stress.

Tip

Work-related stress is defined by the World Health Organization as “the response people may have when presented with work demands and pressures that are not matched to their knowledge and abilities, and which challenge their ability to cope.”

In Canada, 62 percent of highly stressed workers identify work as their main source of stress. This growing concern is also reflected globally; Japan and China, where long working hours are expected, each have a word for death by overwork: karoshi and guolaosi, respectively.

Learning to adapt to stress

Developing the ability to predict stressors and build self-control by using effective communication, considered a form of emotional intelligence, minimizes stress. Emotional support through leisure time and social connections can also counteract some of the negative effects of stress.

Shatavari

Adaptogens

Natural substances known as adaptogens, used for centuries in Chinese and Ayurvedic medicine to promote a sense of well-being by regulating the adrenal stress response, may help reduce the intensity and negative impacts of stress.

Ashwagandha is an anti-inflammatory and calming tonic that is believed to protect against oxidative stress and prevent premature aging.

Rhodiola is an antianxiety adaptogen that is taken to help boost the immune system and improve mental and physical stamina.

Holy basil (or tulsi) may help promote longevity, relieve fatigue, and elevate mood.

Shatavari is referred to as the queen of herbs because of its traditional use for rejuvenating female hormonal health and normalizing sleep disturbances and insulin secretion.

Simple lifestyle strategies

Focus on these lifestyle factors to help boost resilience, well-being, and balance between work and family or personal life.

Eleuthero is used as a performance and focus enhancer to increase mental alertness and concentration.

Exercise increases endorphins (feel-good neurotransmitters) and helps shed daily tensions.

Good quality sleep helps improve mood and reduce stress.

Mindfulness practices such as meditation can restore calm and peace even after just a few minutes.

Spending time in nature helps buffer against stress and correlates with higher rates of happiness and cognitive performance.

Soluble or insoluble? Fibre of any type is not a glamorous topic, but lowly fibre is essential for gastrointestinal health, and it provides many other health benefits.

Often described as “roughage,” fibre was considered to be an inert part of food that simply passed through our intestinal tracts undigested, with little to offer in the way of nutrition. Over time, research has shown that fibre is an essential nutrient with widespread health benefits, making it a vital part of healthy eating. ?

What’s so great about fibre?

Many of us know fibre is important, but we may still be confused about exactly what it is and how it benefits us.

In the field of dietary research, several studies point to the intake of high fibre, particularly from whole grains, as an important dietary intervention for health maintenance. Whole grain foods are an excellent source of fibre, an indigestible carbohydrate, containing many bioactive compounds that offer protection from disease.

The fibre hypothesis

Interest in fibre’s health benefits began in the 1970s when physicians Burkitt and Trowell identified differences between disease patterns in Africa and the Western world. They observed that the Africans studied had a lower prevalence of heart disease, diabetes, and cancer than did Westerners. The researchers attributed this to the plant-based diet eaten by the African population, giving rise to the “fibre hypothesis” suggesting that whole grains, fruits, and vegetables provide fibre that is necessary for optimal health.

According to Canadian guidelines, healthy adults need 21 to 38 g of fibre daily. The average intake is currently about 14 g daily.

For improved health and digestion, both soluble and insoluble fibre should be consumed.

Soluble fibre

This type of fibre attracts water and turns to gel during digestion, which slows down the digestive process. This decreases the absorption of nutrients such as starch and sugar, resulting in lower cholesterol levels over time, as well as improved glucose tolerance.

Insoluble fibre

On the other hand, insoluble fibre gives stool its bulk and speeds its passage through the gut. Like a sponge, it absorbs many times its weight in water, swelling up and eliminating feces, thereby regulating bowel function.

Benefits of consuming fibre

Fibre-rich foods contain antioxidants, magnesium, selenium, vitamin E, and phytic acid, which help maintain glucose and insulin homeostasis, while also suppressing oxidative damage and reducing inflammation.

Recent research indicates that a generous intake of dietary fibre reduces the risk of developing

1. cardiovascular disease (CVD)
2. hypertension
3. stroke
4. diabetes
5. obesity
6. certain gastrointestinal disorders

Heart health

Multiple observational studies substantiate the protective effects of fibre on heart health. Seven cohort studies comprising over 158,000 individuals indicate that CVD prevalence is 29 percent lower in individuals with the highest intake of dietary fibre compared to those with the lowest intake.

Blood pressure

Studies on the effects of increasing oat fibre intake on blood pressure resulted in a modest to moderate reduction in systolic and diastolic blood pressure.

Stroke

Ischemic stroke has been shown to be reduced by 26 percent in other studies.

Hardening of the arteries

In one study of 229 postmenopausal women, six or more servings of whole grain products per week decreased coronary atherosclerotic progression, commonly called hardening of the arteries, by 40 percent.

Cholesterol levels

Soluble fibres have significant cholesterol-lowering effects, as shown in studies using psyllium or oat beta glucan, where LDL (“bad”) cholesterol is reduced without affecting HDL (“good”) cholesterol. In the small intestine, these fibres increase viscosity and bind bile acids, decreasing their absorption and reducing the amount of cholesterol available for LDL synthesis.

Metabolic syndrome

Elevated blood lipid levels along with high insulin levels, excess abdominal fat, and high blood pressure are a constellation of factors describing metabolic syndrome. This condition has been shown to improve when fibre intake is increased.

Diabetes

The incidence of diabetes continues to rise worldwide. A wealth of evidence links high fibre intake with reduced glucose and insulin responses and increased insulin sensitivity. Recently, the Finnish Diabetes Prevention Study reported a trial in which individuals with the highest level of fibre consumption had a 62 percent reduction in the progression from prediabetes to diabetes over a four-year period compared to those with the lowest fibre intake.

Furthermore, glycemic control has been shown to improve in diabetics, reducing the need for medication and insulin in these individuals. Findings from a systematic review indicated a 26 percent reduction in the development of type 2 diabetes among individuals consuming three to five servings of fibre daily.

Weight loss

Whole foods are digested more slowly, allowing for greater nutrient absorption, and make us feel full sooner than processed foods do. Given that approximately 80 percent of people with type 2 diabetes are obese, weight loss is a high priority for diabetes management. A large French cross-sectional study of 5,961 subjects revealed that low fibre intake was associated with elevated body mass index and higher waist-to-hip ratios.

Gastrointestinal health

Dietary fibres elicit a wide variety of actions in the gastrointestinal tract, which is also our largest immune organ. In the colon, fermentable fibres interact with gut flora to promote healthy bacteria such as lactobacilli and bifidobacteria. These generate short-chain fatty acids that stimulate the immune system, aid in digestion, and facilitate the absorption of nutrients.

Constipation, acid reflux, and hemorrhoids are commonly prevented and treated with high fibre intake. Evidence also supports a reduced risk for developing colorectal cancer when a high fibre diet is consumed. The protective effects are due to the ability of fibre to dilute fecal carcinogens and bind carcinogenic bile acids, allowing for their excretion.

It’s abundantly clear that fibre-rich foods have health-protective benefits. These foods often have a low fat content, are rich in micronutrients, and exert a significant impact on the prevention and treatment of various diseases.

Drink more water

For optimal health, we should consume at least 25 g of fibre daily. Of equal importance when consuming more fibre is to drink eight to 10 glasses of water per day, as fibre absorbs water. Increase fibre consumption gradually to avoid bloating and abdominal cramps.

Research confirms the benefits of fibre. Incorporating this simple nutrient into our diet is a simple way to maintain good health.

Benefits of whole grains

Whole grains consist of bran, germ, and endosperm components. Refined carbohydrates typically retain the endosperm, but remove other biologically active agents such as fibre, vitamins, minerals, antioxidants, plant compounds such as lignans and phytosterols, as well as the bran and germ. It is these components, however, that benefit health through their effects on glucose balance, lipid and lipoprotein reduction, endothelial function, and other mechanisms.

Testosterone does more for men than rev up their sex drive. It’s also an important hormone for cardiovascular health. Learn how to improve testosterone levels naturally.

Intriguing and often misunderstood, testosterone is primarily a male hormone with quite the personality. Associated with all that is stereotypically masculine, such as strength, muscular power, virility, dominance, and even aggression, it stands out as the hormone of sexual desire and motivation in men.

King of hormones

Sex

Known as the “king of hormones,” it is certainly the most important of the male hormones, called androgens, that create and support masculinity. Prior to birth, testosterone influences the sex of a baby, and its function peaks at puberty, during which male secondary sex characteristics develop.

Intellect

Moving beyond the sexual realm in adulthood, this hormone also governs intellect, thought patterns, self-confidence, assertiveness, and drive in men. It is necessary for the health of bones and muscle mass, proper immune function, elevated energy and mood, and several cognitive functions ranging from memory and attention to strategic planning.

Heart

Recent research is highlighting this powerful hormone as a significant factor in the health of the heart and blood vessels. Current evidence strongly suggests that testosterone exhibits many cardioprotective actions.

Low levels = cardiovascular disease?

Although the age-related decline of testosterone is well established among many male populations, there appears to be a link between low levels of this hormone and the onset or progression of cardiovascular disease in men. In recent findings, as many as one in four men found to have cardiovascular heart disease (CHD) have low serum levels of testosterone, a condition generally termed hypogonadism.

Testosterone is a male hormone produced from cholesterol and is abundant during adolescence, with levels declining after the age of 30. While the levels drop gradually (about 1 percent per year after age 30), a 2006 American study in the Journal of Clinical Endocrinology and Metabolism shows levels in men have been declining steadily over the past two decades. Of even greater significance is the steeper fall of the biologically active fraction of this hormone, which is the free testosterone known to modulate much of this hormone’s biological effects.

What’s the connection?

So how exactly does testosterone exert its numerous effects? Much like a “lock and key,” the hormone binds to receptor sites that exist all over the body. Interestingly, coronary vessels have the most testosterone receptors. And this is where many of the actions related to cardiovascular function are mediated by this hormone.

Coronary artery narrowing

Dilation of the vessels causing relaxation of the arterial wall, and therefore increased blood flow, is one such effect. Again in cases of coronary obstruction, a direct relationship between coronary artery narrowing and reduced testosterone levels has been shown. It should be noted that testosterone converts to estradiol that stimulates nitric oxide—also a potent vasodilator.

Increased arterial thickness

Testosterone deficiency appears to exacerbate risk factors for developing atherosclerosis and insulin resistance. In examining this relationship, an increase in total cholesterol and low-density lipoprotein, as well as rising blood pressure, increased thickness of the arterial wall, and an increase in the production of proinflammatory factors have been reported.

Endothelial damage leads to plaque buildup

Low serum testosterone is associated with high blood pressure in older men, as well as stiffness of the arteries, which subsequently leads to damage inside the blood vessel. This endothelial damage triggers inflammation in the vessels, eventually causing the buildup of plaques that, if unstable, can erupt at any time, resulting in a rather abrupt and unpleasant outcome.

Atherosclerosis is not typically a problem of cholesterol; rather, it is a problem of oxidative stress and inflammation. And so it comes as no surprise that certain inflammatory mediators are actually inhibited by testosterone.

Studies have also demonstrated that when men were treated with testosterone, all of the parameters mentioned above improved, suggesting the importance of this hormone in preserving cardiovascular health in men.

Body composition changes

Testosterone influences body composition in men, which is altered in the presence of low levels, resulting in increased waist circumference, central obesity, and waist-to-hip ratios, as well as a decrease in muscle mass.

Symptoms of low testosterone

So how does one determine if testosterone deficiency is a health concern? The following are among the most prevalent symptoms:

1. low energy or strength
2. decrease in sexual sensation and performance
3. depression and mood changes
4. lack of mental clarity and motivation
5. sleep disturbances
6. decreased axillary, facial, or pubic hair
7. weakness, increased fat, and decreased muscle mass
8. osteopenia or osteoporosis

Testing

Evaluation of total and free testosterone levels is the standard choice for screening for deficiency. This hormone typically demonstrates a circadian rhythm, so serum measurements are taken in the morning, depending on the man’s age. It is important to consult with a knowledgeable health practitioner for appropriate lab work and thorough assessment of other possible underlying conditions.

Testosterone is a multifaceted hormone that extends beyond its sexual attributes and is a broad-spectrum player necessary in several aspects of men’s health. It has been described by men’s health doctors as “jet fuel that keeps a man running” and is vital to a man’s sense of physical, emotional, and mental well-being. 

Improving testosterone levels naturally

Natural health strategies can improve testosterone levels and enhance cardiovascular health.

Foods

Increase protein intake and healthy fats from foods including

1. nuts
2. seeds
3. salmon
4. avocados

Get more zinc from foods such as

1. oysters
2. pumpkin seeds
3. legumes

Supplements

Crucial for heart health and normal lipid metabolism:

1. high quality omega-3 fatty acids
2. antioxidants such as vitamin C
3. fibre

Herbals

Botanicals that have traditionally been used to enhance sexual vitality, balance hormones, and improve circulation include

1. maca
2. hawthorn
3. Ginkgo biloba
4. horny goat weed
5. Tribulus terrestris
6. Ginseng is widely reputed for its antistress and adaptogenic properties, because stress stimulates cortisol production, which blocks the effects of testosterone.

Lifestyle

Of course, lifestyle factors such as adequate sleep and strength training exercises enhance heart health and boost testosterone levels naturally.

Type II Diabetes is a chronic disease with several complications, that has reached epidemic proportions. Improper and unhealthy dietary habits result in an overproduction of Insulin making cells resistant and incapable of regulating glucose levels effectively. This then leads to prediabetes, although millions of individuals are undiagnosed until serious symptoms and organ damage take place. The good news is that Naturopathic strategies are very effective at reversing and preventing Type II Diabetes and Insulin Resistance if diagnosed early. Addressing mineral deficiencies is a key factor, and the use of correct dietary therapy and botanicals are also important.

Up to half of all causes of infertility are related to the male partner. We explore the causes, diagnoses, and natural remedies to increase male fertility.

Reproduction and childbirth are important decisions for many couples, and having a baby can be a wonderful and fulfilling experience. But when conception and pregnancy don’t come easily, feelings of anxiety, distress, and frustration often arise. It is estimated that up to half of all cases of infertility are due to factors related to the male partner. Here are some possible causes and solutions.

Infertility is widespread

Globally, as many as 14 percent of couples are infertile, which is defined as the inability of a sexually active couple to get pregnant after one year of regular, unprotected intercourse.

While social factors (such as the increasing age at which people marry) are at play, environmental factors, such as pollution and environmental toxins are other influences behind the prevalence of couples facing infertility today. Thankfully, there are simple things men can do to help boost their fertility.

Diagnosis

When infertility is in question, how is it diagnosed? Getting a thorough reproductive checkup is always a good first step. Typically, a health care practitioner will begin with a medical history, including concerns such as past infections or sexually transmitted diseases, damage to the reproductive organs, medications, and exposure to toxins.

A physical exam and a semen analysis are also done to look for the number, movement, and shape of the sperm. A sperm count of approximately less than 20 million/mL usually confirms the diagnosis. An absence of sperm in the ejaculate, also known as azoospermia, occurs in approximately 10 percent of cases.

Other tests that may be done include a scrotal or transrectal ultrasound to assess any blockages in the sperm pathway, or blood tests to determine any hormonal deficiencies.

Causes and solutions

Many different conditions can lead to infertility—some that you may be able to address yourself, and some that require expert assessment and treatment.

Examples of infertility causes that need to be addressed by a qualified health care practitioner include

1. enlarged veins in the testes (varicocele)
2. genetic disorders
3. blockages in the passage of the sperm from the testes to the penis
4. sexually transmitted diseases
5. prostatitis (inflammation of the prostate)
6. mumps orchitis (inflamed testicles due to mumps)
7. hormone problems (see below)

Hormone problems

Hormones play a vital role in initiating and maintaining male reproductive function.

1. Testosterone is essential for the growth and division of germinal cells that form into healthy sperm; a deficiency of this hormone contributes to infertility.
2. The interplay of other hormones such as LH (luteinizing hormone) and FSH (follicle-stimulating hormone) comprise the delicate endocrine balance necessary for maturation of sperm cells.
3. The quality of semen is also associated with another hormone, known as inhibin B.
4. Research also identifies thyroid hormone receptors on the testes, suggesting the significant impact of this hormonal system on the male reproductive tract. An abnormal thyroid profile can affect semen quality and fertility by compromising testicular size, sperm motility, and ejaculate volume.

Oxidative stress

Male infertility is a complex process often diagnosed as “idiopathic” meaning that standard evaluations can’t determine a cause. Considerable evidence is now pointing toward oxidative stress as a factor in male infertility.

Oxygen is essential to sustain life, and as part of the normal metabolic process, sperm produce reactive oxygen species (ROS), which are necessary to maintain normal cell function. However, when ROS are present in excessive amounts, either due to increased generation or impaired clearance, they reduce sperm motility and cause extensive sperm DNA damage.

Seminal fluid contains the highest concentration of antioxidants of any human fluid. Antioxidants protect from damage caused by ROS, and several clinical trials support the use of antioxidant therapy such as vitamins C and E, zinc, coenzyme Q10, and carnitine to improve sperm parameters. Of course, always consult a health care practitioner before taking new supplements. Here are some examples of this recent research.

1. Vitamin C neutralizes free radicals, protecting against DNA damage. One 2006 study found that administering vitamin C daily for two months increased sperm count in men.
2. Coenzyme Q10 is an antioxidant that helps protect the sperm against oxidative damage and supports cellular bioenergetics by providing important fuel for sperm motility.
3. Carnitine is a key transporter molecule that also has antioxidant effects. Many studies have suggested that carnitine can help improve sperm concentration and motility (giving weak sperm a much-needed energy boost) and increase pregnancy rate.
4. Zinc plays a role in testicular development, sperm maturation, and production of testosterone. A 2008 study found that zinc supplementation improved sperm motility and prevented oxidative damage. Another study, this one from 2012, found that older men with higher dietary zinc intake produced sperm with less DNA damage.

Environmental toxins

Infertility in men is also influenced by occupational elements and environmental pollutants. Male reproductive function can be compromised by exposure to chemicals such as heavy metals, pesticides, and xenoestrogens.

Many toxic chemicals act as endocrine disruptors—interfering with hormonal processes—and subsequently impair sperm function. Bisphenol A (BPA) is an example of a compound that may impact male fertility. This widespread chemical can be found in plastic bottles and food containers, the lining of cans, thermal paper (receipts), medical equipment, and electronics.

Phthalates are another group of widely used substances (in soft plastics products such as shower curtains and skin care products) that have been shown to inhibit testosterone synthesis.

Limit your toxic load by avoiding the aforementioned products when possible or choosing nontoxic options. For instance, opt for organic to reduce your pesticide exposure, choose canned goods labelled with the words “BPA-free,” and look for “phthalate-free” on skin care products.

Lifestyle

Lifestyle factors play a pivotal role in the overall health and well-being of a man’s reproductive function.

1. Weight: Obese men are three times more likely to exhibit low sperm quality than men of a healthy weight. Overweight men, too, exhibit increased DNA damage to sperm.
2. Exercise: A healthy amount of exercise (at least three times a week for about an hour) is beneficial to improve all sperm parameters—but too much rigorous exercise may be detrimental.
3. Nutrition: Try to consume a diet rich in whole foods, fibre, folate, and lycopene-containing fruits and vegetables such as tomatoes and watermelon.
4. Smoking and drinking: Find support to help stop smoking, and limit your alcohol and caffeine consumption.
5. Stress: Also consider reducing your stress levels by engaging in mindfulness-based exercises or attending counselling.

A complementary approach

Addressing infertility can be a very stressful and complicated process. Working with a medical doctor, urologist, psychologist, or other qualified health professional is essential to address the various elements involved.

Naturopathic doctors are also well-trained in assessing and managing this condition and often conduct an environmental toxin assay or oxidative stress test, along with using botanicals and other natural medicines to address hormonal imbalances. Ultimately, knowledge and support are instrumental in successfully overcoming infertility.

Fact or fiction?

While the type of underwear men wear likely won’t make a difference to sperm count, there are a few surprising things that can—at least temporarily—reduce sperm count by overheating the testicles, including

1. frequent sauna and hot tub use
2. using a laptop computer for a prolonged period of time
3. cycling for a long duration

True personalized medicine is predictive, precise, preventive and participatory.  Genetic testing and nutrigenomics are the future of individualized healthcare.  The impact of diet, lifestyle, exercise and environment on an individual’s genetic makeup influences how the genes function and subsequently results in outcomes related to health or disease.

Genes are made up of DNA (deoxyribonucleic acid) providing two copies of each gene, one inherited from each parent.  DNA consists of nucleotides, 99% of which are identical between individuals, but the remaining 1% contain small variations known as SNPs (singl nucleotide polymorphisms). These genetic variations or SNPs can have profound effects on how genes function and in turn affect the biological pathway in which the gene is active.  Metabolic areas requiring intervention and support can then be identified to enhance a state of health.  This is a powerful advantage in assembling a naturopathic protocol that is truly customized to the individual.
