Is your oral microbiome wrecking your endocrine health?

By Mark Burhenne, DDS

As a functional dentist, I’ve been coaching patients for years on the best ways to prevent and reverse oral disease. After all, the health of the mouth directly impacts and mirrors the health of your whole body!

In recent years, research on the oral microbiome has revealed just how important the optimal balance of bacteria is in your mouth. Not only can a dysbiosis of the oral microbiota lead to dental problems, like cavities and gum disease, but an imbalance of the oral microbiome is closely related to systemic diseases, too.

In particular, issues with oral bacteria can greatly impact the health of your endocrine system, from menopause to pregnancy outcomes to diabetes and beyond.

If you’re wondering why your endocrine health is still a problem, your oral microbiome might be the source of your concern. Let’s take a look.

 

What is the Oral Microbiome?

The oral microbiome (also called oral biome or oral microbiota) is basically what it sounds like: a community of bacteria that lives in your mouth. [1]

These bacteria live on all the surfaces within your oral cavity, like your teeth, gums, tongue, and the floor of your mouth.

Similar to the gut microbiome, the oral microbiome needs bacteria to be healthy. The microbial communities in the human mouth help to support the health of your mouth and entire body. Even “pathogenic” bacteria, known to cause disease, are generally present in certain amounts.

More than 700 species of bacteria have already been identified in the human oral microbiome. This collection of bacteria is second only to the gut microbiome for diversity and bacterial population. [2]

One major reason the oral microbiome is important is that it’s the largest “seeder” of bacteria to your gut—because you swallow 140 billion organisms per day! If your oral health is out of whack, it can affect your gut microbiome’s health, too. [3]

Why is this so important? Because if you want to live a healthy life and prevent or reverse disease, the root cause of your health problems must be addressed. For many people, this root cause lies with the oral microbiome… and they’re not even aware of it.

5 Ways Your Oral Health Affects Endocrine Health

It’s fairly well-established that your gut microbiome has an impact on endocrine health and disorders, like diabetes, adrenal fatigue or insufficiency, and even women’s health concerns. [4]

As it turns out, the same is true about your oral microbiome. A 2018 review of the current research explains how dysbiosis of the oral microbiome is related to: [5]

And it doesn’t stop there …

1. Diabetes

The most well-known endocrine disorder, diabetes, is understood to be preventable in many cases. It’s a disease that has “multiple etiologies,” or a wide range of factors that are known to increase your risk. One of these etiologies is the oral microbiome.

The link between periodontitis (gum disease) and diabetes is pretty clear—if you have gum disease, you are far more likely to suffer from diabetes (and vice versa). [6]

Patients with both uncontrolled diabetes and chronic gum disease have significantly dysbiotic oral microbiomes. [7] This means they test for high levels of pathogenic bacteria but have fewer species and communities of “commensal” bacteria (sometimes called “healthy” bacteria).

2. Menopause

As you can imagine, the oral microbiome changes throughout menopause (just like your gut microbiota). Post-menopausal women are also at a greater risk of a number of issues related to bacterial communities, such as estrogen deficiency, periodontitis, and overall chronic inflammation.

Alterations in the oral microbiome during menopause aren’t consistent so far in the available research we can access. However, here’s what we do know:

3. PCOS

Polycystic ovary syndrome, or PCOS, is an endocrine disorder responsible for more cases of infertility than any other single cause. It’s already linked to dysbiosis in the gut microbiome. [12, 13]

A small 2016 pilot study found that women with PCOS had fewer strains of Actinobacteria, a commensal family of bacteria, than healthy controls. [14] While this isn’t conclusive proof of anything quite yet, it’s possible that oral health plays an important role in the progression of PCOS.

4. Obesity

Nearly 40 percent of Americans were obese between 2015-2016, according to the CDC. Obesity, like many other endocrine diseases, is multifactorial (not just one trigger is to blame).

A fascinating study in 2009 examined over 500 samples of oral bacteria in men and women, a little over half of whom were known to be obese. [15] One bacterial strain, in particular, Selemonas noxia, was found in significantly higher concentrations in the obese subjects.

In fact, 98.4 percent of the subjects with obesity could be identified on paper by the presence of that bacteria alone, which was not present at those levels in any of the healthy weight subjects.

5. Pregnancy & Delivery Complications

Known as Adverse Pregnancy Outcomes, APOs, issues with pregnancy and delivery may also have their roots in a dysbiotic oral microbiome.

When I work with women working to conceive, I stress the importance of addressing dysbiosis and any signs of gingivitis or gum disease before conception if possible.

Dysbiosis of the oral microbiome has been associated with:

Is your oral microbiome dysbiotic?

There are a few tests that your dentist can administer to test your oral microbiome, but they’re not widely available yet.

The simplest way to identify a dysbiotic oral microbiome is to look for the signs:

All of these are, for the most part, preventable. If you’re experiencing them, something is out of order with your oral microbiome.

Another major hint that you have a dysbiotic oral biome is your diet. High-sugar/high-carb diets are the hardest on your oral microbiome, so if you regularly eat sugary, starchy, processed, and/or acidic foods, chances are that you might need to address your oral health.

How to Improve Oral Microbiome Health

There are a few different processes involved in bumping up your oral microbiome health: disorganizing existing bacteria, supporting/increasing commensal bacteria, and avoiding bacteria-killing habits.

To DISORGANIZE your oral bacteria:

To INCREASE your commensal bacteria:

To AVOID building up unhealthy oral bacteria or killing off the good stuff:

5 Amazing Health Benefits of Acupuncture (+ How It Works!)

You've probably heard of acupuncture, and maybe even some of the health benefits of acupuncture, before. But have you had any personal experience with it? I have, both as a patient and as a practitioner.

Acupuncture has been around for a very, very long time. You may be surprised to learn that this complimentary, or natural, therapy was actually pioneered well over 3,000 years ago by Chinese practitioners. Here in the U.S., however, we've only just caught onto this therapeutic technique of Traditional Chinese Medicine (TCM) within the last 40 years. With each year, it has become increasingly popular as people have learned more about the many health benefits of acupuncture.

You're probably wondering if acupuncture works, if it's been medically proven, or if it's just a “woo” thing that people believe in. And these are valid questions to ask, so let's get to the point. In this article, I’ll review how acupuncture differs from other types of therapies, how it helps with energy flow, and break down the various health benefits of acupuncture. So, let’s get started and learn all about acupuncture so you can decide if it’s a therapy that may be right for you.

 

What is Acupuncture?

As a practice of TCM, acupuncture is a coherent and independent system of thought and practice, based heavily on critical thinking, extensive clinical observation, research, and testing. It is rooted in philosophy and is logic-based.

Sadly because it’s so foreign to those practicing Western medicine, some see acupuncture, and TCM as a whole, as nothing more than hocus-pocus, or a placebo effect. [1]

The good news is, that couldn't be farther from the truth. First and foremost, acupuncture has been recognized by the World Health Organization (WHO) as an effective treatment.

Additionally, numerous scientific studies have also confirmed the many health benefits of acupuncture. [2] And just as with a TCM practitioner, many states require acupuncture practitioners to be licensed acupuncturists. This can be done through the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM). In some states, though, licensed naturopathic physicians can also sit for acupuncture boards.

How Does Acupuncture Work?

TCM is a philosophy that includes a variety of holistic therapies, such as acupuncture, herbs, tinctures, massage therapy, Qi gong, tai chi, etc., to balance the yin and yang. The concept of yin and yang is a construct of two polar compliments. These complementary opposites are used to describe how things function in relation to each other and the universe.

Acupuncture plays a big role in helping balance the yin and yang by using thin needles, inserting them into the skin to stimulate specific points in the body along a meridian. As an example, let’s say you were dealing with an intense headache. If you went to an acupuncturist, he or she would check your pulse, look at your tongue, and focus on certain acupuncture points called LI4 and LV3, also known as the "four gates." These points stimulate blood circulation, which is excellent for relieving headaches. [3]

Now, it’s important to note that many people who have never experienced acupuncture may be intimidated by the concept. It's been reported that over 20 percent of people have trypanophobia, or a fear of needles. [4] So, it would make sense that many people would be afraid to try it out. But what they don't realize is that the needles used in acupuncture are entirely different from commonly used medical needles.

Acupuncture needles are extremely thin, inserted into the skin, and are placed only in minimal strategic locations on the body to focus on your specific areas of concern.

Speaking of areas of concern and strategic locations, there are over 350 acupuncture points, which are associated with specific organs and organ systems. [5] These points are positioned over 14 meridians, or the energy highways of the body.

I've witnessed first-hand the healing effect acupuncture can have on the human body. Amazingly, people have noticed significant improvements in as little as 30 minutes! What improvements? Let’s take a look at some of the top health benefits of acupuncture.

The Top 5 Health Benefits of Acupuncture

Here are five common health benefits of acupuncture.

1. May help relieve urinary incontinence

Urinary incontinence occurs when urine unintentionally leaks from the urethra, which is known as a loss of bladder control. And there are many underlying causes. These include having a prolapsed uterus, pregnancy, childbirth, hysterectomy, enlarged prostate, neurological disorders, menopause, and changes with age due to the bladder muscles aging.

There are various types of urinary incontinence, too, ranging from stress, urge, overflow, functional, and mixed incontinence. Whatever the case may be, this can be rather uncomfortable and even embarrassing. If you've dealt with urinary incontinence, then you know that coughing, sneezing, certain physical activities, and even laughing can cause leakage.

Luckily, both research and clinical practice have shown that one of the major health benefits of acupuncture is that it can help relieve this condition.

Between 2013 and 2015, clinical trials involving 12 hospitals in China were randomly separated into two groups of 252 participants, totaling 504 patients. Each person was given 18 acupuncture sessions over a period of six weeks, explicitly targeting urinary incontinence.

Of the 504 women, ranging from 40-75 years, 482 completed the treatment. The results showed that treatment with acupuncture on the lumbosacral region (BL33 and BL35) resulted in less urine leakage and episodes of urinary incontinence. [6]

2. Supports healthy blood sugar levels

Another one of the big health benefits of acupuncture is its ability to support healthy blood sugar levels. In fact, acupuncture therapy is a common approach to treating diabetes in China. And many animal studies have shown that acupuncture may be a great complimentary treatment for diabetes.

In fact, a 2018 study showed that acupuncture increased insulin levels and improved glucose tolerance in animals. Furthermore, it lowered glucose each week during the study. [7]

Additionally, another study revealed that diabetic patients with neuropathy who took medications improved by about 37 percent. Meanwhile, those who took medications but also received acupuncture saw an incredible 90 percent improvement in neuropathy symptoms. [8]

3. Can improve asthma symptoms by up to 70 percent

According to the National Institutes of Health (NIH), acupuncture has been recognized as an acceptable alternative or adjunct treatment for many diseases, including asthma. [9]

Asthma affects over 300 million people around the world, and claims over 3,000 deaths per year. The WHO also recognizes asthma as one of the 40 diseases that would benefit from acupuncture.

One study conducted at the University of Vienna Department of Anesthesia and Intensive analyzed 17 patients with a history of asthma. The findings showed that over 70 percent of patients undergoing acupuncture treatment saw a vast improvement in their asthma symptoms in just 10 weeks. Additionally, they saw further improvement over the next six months. [10]

Another study followed 192 patients of varying ages suffering from bronchial asthma. All cases were treated with acupuncture by placing needles at the LU6 and LU10 points. Of all cases, 98.9 percent saw immediate results. Furthermore, the rate of clinical remission plus improvement was 76.5 percent. [11]

4. May boost mood and energy

Another one of the great health benefits of acupuncture is its ability to boost both mood and energy. As you may know, dealing with mood swings, anxiety, and depression can be crippling. Oftentimes, when the seasons shift, the weather changes from bright and sunny to cold and gloomy, a shift occurs in people's moods.

Aromatherapy, exercise, reducing stress, taking herbs, eating a well-balanced diet are all great starting points. Still, many studies have shown acupuncture can help tremendously with mood improvement.

Anxiety and depression are two of the most common psychiatric disorders. And they are more prevalent in women, especially those who are pregnant or postpartum. Six trials were conducted using all women from various backgrounds, all suffering from anxiety, depression, or both.

Of the six separate studies, five used acupuncture as the only treatment, while one used counseling and psychotherapy. The results showed a decrease in symptoms and improvement in mood in those who received acupuncture, especially in those who were pregnant. [12]

Another study was conducted on the effects of acupuncture and the regulation of the central autonomic network (CAN). This network is a necessary part of an internal regulation system in which the brain control responses that are essential for survival, such as pain, neuroendocrine, behavior responses, etc. [13]

This study showed that acupuncture treatment activated distinct brain regions in various diseases caused by an imbalance between the sympathetic and parasympathetic activities. It also alleviated autonomic (involuntary or unconscious) responses by modulating adaptive neurotransmitters in certain regions of the brain. [14, 15]

There’s also another element here that explains why energy improvement is one of the top health benefits of acupuncture. When you’re in a slump and feeling fatigued, you likely think of two things first: at how much sleep you’re getting and your diet. But what if your energy is still lagging, even if your diet and sleeping habits are well-rounded?

This is where balancing your Qi comes into play. Qi, according to TCM, is known as the vital life force, or source of energy that circulates within your body. Loosely translated, one of the first symptoms of an imbalanced Qi is lack of energy. A sufficient amount of Qi is needed to maintain the yin and yang in your body.

Acupuncture increases blood flow and energy flow by stimulating the meridians with the penetration of the needles. When blood flows properly, it transports oxygen and nutrients to organs, allowing them to function properly and boost your energy levels. [16, 17]

5. Helps improve sleep quality

When it comes to sleeplessness, you always want to get to the root cause. Now, there are essential oils that help promote sleep and relaxation, but if your body is off-balance, acupuncture might be something to consider. One of the great health benefits of acupuncture is that it will not only improve your sleep but also the quality of sleep you're getting.

In TCM, acupuncture commonly is used to treat insomnia. One study including 46 randomized trials and 3,811 patients compared acupuncture versus no treatment, and acupressure versus sham acupressure (a placebo effect).

The result showed acupuncture was superior compared to other treatments or placebos for improving sleep quality. Therefore it is shown as an effective treatment for sleep and those suffering from insomnia. [18, 19]

Other health benefits of acupuncture include, but are not limited to:

 

It's clear to see that acupuncture isn't just hocus-pocus, right? It's been proven through several studies and assessments that it aids in the healing process. Even in studies with placebo effects where both strategic needling and non-strategic needling took place, those with strategic needling along the meridians showed lasting relief. The philosophy here is to find the imbalance and, therefore, provide the solution, which is TCM—and its many practices—in a nutshell.

6 Amazing Arugula Benefits: Fight Obesity, Diabetes, and More!

As a doctor, many of my patients, friends, and family often ask for dietary advice. They simply want to know what I eat and which foods have the most nutritional content and health benefits. And I’m always happy to share my favorites, which include avocados, sweet potatoes, mangoes, almonds, figs, and more. Also making the list? Arugula! And there’s a special reason why: Arugula benefits are simply amazing.

Versatile and easy to add to many different foods, arugula is one of my top greens. As a result, I consume it on a regular basis—and recommend that others follow suit. But I’ve found that many people aren’t as familiar with arugula as they are other green leafy vegetables. So, let’s review what makes arugula so healthy, some of the top arugula benefits for your health and wellbeing, and some quick and easy ways you can add it to the foods you already know and love!

 

What Makes Arugula So Healthy?

Arugula is a green leafy cruciferous vegetable that’s high in nutrients. This is important to note because cruciferous vegetables are known to be excellent sources of vitamins A, C, and K. They also contain minerals such as folate and phytonutrients, which help fight inflammation and, as a result, help prevent harmful diseases.

Arugula also contains significant amounts of calcium, iron, potassium, and more, making it a truly powerful source of nutrition. As a result, it’s actually one of the top foods for detoxifying your liver.

In fact, studies have shown that isothiocyanates (small molecules derived from the glucosinolates, or sulfur-containing compounds, found in cruciferous vegetables) increase the detoxification of carcinogens in the body. [1]

But that’s not all cruciferous vegetables, such as arugula, do. Researchers have found that cruciferous vegetables are high in fiber, which is known to promote digestive wellness. And, interestingly, proper digestion is known to support your overall mood!

A 2018 study revealed there are 12 nutrients that help to prevent and even treat depressive disorders. These nutrients are: folate, iron, omega-3 fatty acids, magnesium, potassium, selenium, thiamine, vitamin A, vitamin B6, vitamin B12, vitamin C, and zinc.

It’s amazing how many of those nutrients are found in arugula and other cruciferous vegetables! In fact, the researchers noted that some of the highest scoring plant foods included cruciferous vegetables, and, specifically, leafy greens. [2]

Interestingly, when it comes to arugula, it’s quite easy to get more of it into your diet. You can eat it raw and simply add it into your salad or sandwich. But you can also sauté it lightly and add it on top of savory dishes, such as pizza or pasta.

Now that we’ve discussed the nutritional content of arugula, the benefits of cruciferous vegetables, and even how to get more arugula into your diet, let’s get a little more specific. Keep reading for information on the top arugula benefits!

 

 

6 Surprising Arugula Benefits

So, what are the benefits of eating arugula? Take a look at six of the most surprising arugula health benefits below.

1. Supports bone health

As I mentioned above, arugula is rich in vitamin K, with one cup containing 21.8 micrograms of vitamin K. But what you may not now is that vitamin K is incredibly important for your bone health. Why? Well, without vitamin K, your body can’t absorb calcium properly.

In fact, numerous studies have shown that vitamin K not only helps to increase bone mineral density in people with osteoporosis, but it also helps to reduce their fracture rates! [3] Moreover, additional studies have shown that vitamin K can be especially beneficial to postmenopausal women by providing significant improvements in their bone mineral density. [4]

So, thanks to its vast amounts of vitamin K, arugula benefits your bone health and may even help fight osteoporosis.

2. May contain anti-diabetic properties

When it comes to maintaining healthy blood sugar levels, it’s no surprise that eating plant-based foods is the key.

In fact, a 2019 meta-analysis of nine studies covering over 300,000 participants revealed that people who adhere to a plant-based diet have a 23 percent lower risk of developing diabetes than those who don’t. [5]

Additionally, plant-based diets have also been shown to reduce stress. A 2009 study showed that participants who reduced their animal-based food intake experience elevated moods and felt less stress and anxiety. [6]

Here’s where this all comes together: Because arugula is rich in alpha-lipoic acid (an antioxidant known to help lower glucose levels), one of the biggest arugula benefits is that it can actually help to counteract stress-induced changes in your blood sugar levels! How incredible is that? Studies have even shown that alpha-lipoic acid can benefit patients with diabetic neuropathy. [7]

Finally, a 2017 animal study revealed that arugula extract exhibited anti-diabetic activities in insulin-responsive cell lines. The researchers surmised that it may prove useful in treating type 2 diabetes. [8]

3. Fights dehydration

Dehydration is a natural occurrence that happens anytime your body uses or loses more water than it needs to function properly. If you’re able to replace these fluids, you will resolve the dehydration by becoming properly hydrated. But, if not, it can cause a myriad of concerns—from simply feeling a little “off” to constituting a medical emergency.

Contrary to popular belief, staying hydrated is about more than just drinking enough water. While I do recommend drinking half your body weight in ounces of water daily, I’ve also found that consuming hydrating foods is key as well. Luckily, one of the most interesting arugula benefits is its ability to promote hydration.

You may be surprised to learn that arugula is actually made up of about 90 percent water. This makes it a great hydrating food. Not only that, but studies have shown that simply adhering to a plant-based diet, which is high in nutrients, can also help ensure that you consume plenty of water-rich foods. [910] Sounds like a win-win, right?

4. Contains anti-inflammatory properties

We discussed above how the isothiocyanates in arugula have cancer-fighting properties. But did you know that they’re also known to fight inflammation?

A 2013 study revealed that these isothiocyanates contained potent anti-inflammatory activity and inhibited the pro-inflammatory enzymes and cytokines in animal models. [11]

Furthermore, researchers followed the eating habits of over 1,000 women in a 2014 study. They found that those who ate more cruciferous vegetables, such as arugula, had up to 24 percent less inflammation in their bodies than those who ate less cruciferous vegetables. [12]

Because inflammation is often a precursor to many of our chronic diseases today, this arugula benefit alone is a great reason to incorporate more of this health-promoting vegetable into your diet!

5. May help boost libido

Arugula has been used for its aphrodisiac properties for centuries. [13] Traditionally, arugula was believed to help rid the body of harmful toxins believed to lower libido. But that’s not all.

Due to its inflammation-fighting properties, arugula benefits not only whole-body health but also your libido.

Interestingly, numerous studies have linked inflammatory disorders with sexual dysfunction. [14, 15, 16, 17] But a 2013 study revealed that arugula extracts actually significantly increased testosterone levels and sperm activity in mice. Furthermore, the researchers found that the extract results in a significant decrease in sperm mortality and abnormalities. [18] As a result, the findings show that arugula benefits may include sexual function support.

6. Supports healthy weight management

Thanks to its high nutritious value and water content, arugula benefits extend to healthy weight management as well. As we’ve discussed, it’s also high in fiber, making it filling, which aids in satiety.

Interestingly, an analysis published in 2015 revealed that consuming a diet high in non-starchy vegetables, such as arugula and other cruciferous vegetables, is linked to higher satiety and less weight gain. [19]

Arugula is also notoriously low in calories, making this filling food a great option if you’re hungry but watching your food intake.

The Top 5 Traditional Chinese Medicine Herbs: What They Do and How They Work

You may be surprised to learn that more than one-third of all Americans regularly use complementary and alternative medicine as their preferred method of treatment. And it’s with good reason—even though it’s now called “complementary” and “alternative” treatment, the truth is that natural therapies have been used for thousands of years. This is especially true of Traditional Chinese Medicine, which has been practiced for over 2,000 years. [1]

Traditional Chinese Medicine is a holistic therapeutic practice based on ancient Chinese philosophy. It includes three different approaches: Traditional Chinese Medicine herbs, acupuncture, and tai chi. But, aside from its philosophical roots, how does Traditional Chinese Medicine differ from other natural therapies? Let’s take a look at what makes it unique and discuss the top Traditional Chinese Medicine herbs and the health benefits they offer.

What Is Traditional Chinese Medicine?

At its core, Traditional Chinese Medicine is based on the ancient Chinese philosophy that all humans are simply one part of the universe and, as a result, we are irrefutably connected to nature and subject to and/or affected by all its forces. Therefore, finding a balance with nature and the universe is seen to be key to obtaining optimal health. Accordingly, the goal of Traditional Chinese Medicine is to either maintain or restore optimal balance in each individual person. [2]

According to Traditional Chinese Medicine, to achieve optimal balance with nature and the universe, your Qi (also known as the vital life force or source of energy that circulates within your body) must be in balance. This means that all of your body’s internal organs must exist in harmony and support one another. Any imbalance to your Qi may result in illness.

Another element of Traditional Chinese Medicine is based on the belief that the body contains 12 meridians, or energy pathways. The main job of each meridian is to facilitate the flow of Qi, fluid, and even your blood throughout your body.

These meridians differ slightly from how we view organs in Western medicine. For example, the meridian for the lung is actually on your arm, not over your lungs. If you visit an acupuncturist for asthma, this is why he or she will likely use many points in your arm to move energy through the meridian.

Traditional Chinese Medicine practitioners also rely on the concept and yin and yang. Yin and yang are known as energies within your body that are completely opposite yet complement each other to result in balance. Examples include wet and dry or cold and heat. Think about it like this: You don’t want to be too hot or too cold, right? You want it “just right.” Like Qi, any imbalance between your yin and yang are believed to result in disease. [3]

When any imbalance occurs, the goal with Traditional Chinese Medicine is to regain that balance. And, according to the philosophy, this balance is obtained based on five elements, and everything in the universe can be attributed to one of these elements. They are: wood, fire, earth, metal, and water—each of which represent the stages of life and also explain how your body functions as one cohesive being. Think of each human as a unique blend of these elements.

Sound confusing? It can be! Luckily, there are many doctors and Traditional Chinese Medicine experts out there to assist you. For me, it took four years of study before I even started to grasp the subject. It’s not only a science, but an art, and it has been used successfully for thousands of years.

In general terms, in Western medicine, we diagnose a symptom or disease—much like an invader in the system that needs to be suppressed. In Traditional Chinese Medicine philosophy, practitioners diagnose the imbalance of energy, with the goal of rebalancing the natural flow of energy throughout your body.

Treatment is supportive, not suppressive. For example, a doctor who practices Traditional Chinese Medicine may tell you that you have “external wind-cold” or “internal wind-heat” and never diagnose the actual virus impacting your system! Why? Because it’s not needed to treat you. The philosophy is simple: Find the imbalance, find the solution! So, in this example, the treatment would require herbs and acupuncture points that balance the wind and cool the heat.

So, let’s take a closer look at how someone would diagnose using this philosophy.

 

 

The Traditional Chinese Medicine Diagnostic Process

While conventional practices and standard treatments take a reactive standpoint based on a diagnosis, Traditional Chinese Medicine is more proactive when it comes to health by determining the underlying imbalance. This is done by looking at your tongue, feeling your pulse, and considering your history and symptoms. The goal is to determine:

  1. Which meridians are affected.
  2. What elements are impacted and if they’re excess or deficient in the meridian.
  3. What the best treatment is, based on the imbalance (i.e., clearing wind or adding heat).

So, for example, let’s say you visit your typical doctor. After explaining your symptoms of heavy menstrual cycles, lack of sleep, and generalized worry, she diagnoses you with insomnia and anxiety and refer you to the gynecologist. She offers you an anti-depressant and a sleeping medication, and possibly refers you for a sleep study.

If you were to visit a Traditional Chinese Medicine doctor with the same symptoms, she may diagnose you with “Heart Fire” due to a bright red tip on your tongue and a strong pulse. “Heart Fire” is a diagnosis of excess, resulting in heat that causes inflammation, which impacts more than just one area of the body.

Often, someone with this diagnosis experiences insomnia, hot flashes, anxiety, racing heart rate, dry mouth, and generalized tension. To treat this condition, the doctor may use acupuncture points and herbs designed to clear heat from the heart meridian, therefore balancing all of your reported symptoms with the same treatment. Pretty neat, huh?

Below is a general diagram of the basic meridians of the body on the tongue. It is quite a bit more involved with this, but perhaps it will be fun to take a quick peek at your tongue.

Now let’s take a look at some of the top Traditional Chinese Medicine herbs that practitioners use to aid healing.

5 Top Traditional Chinese Medicine Herbs

Here are the top five Traditional Chinese Medicine herbs and their uses.

1. Astragalus

One of the most widely used of all Traditional Chinese Medicine herbs, astragalus is known to support kidney health, heart health, and even the immune system.

A 2014 review revealed that astragalus use significantly decreased not only the amount of protein in subjects’ urine (often associated with kidney disease), but also decreased both systolic and diastolic blood pressure. [4]

Interestingly, a 2016 study also revealed that astragalus increased the efficacy of platinum-based chemotherapy while also decreasing toxins derived from platinum in patients with non-small-cell lung cancer. [5]

2. Cinnamon

According to Traditional Chinese Medicine philosophy, pungent herbs and spices such as cinnamon promote the circulation of Qi and body fluids. Conversely, the sweetness of cinnamon can aid in detoxification. [6] But cinnamon is known to do even more.

One of cinnamon’s most beneficial health effects is its inflammation-fighting power. In a 2014 study, researchers tested the anti-inflammatory activities of 115 foods and found that cinnamon was one the most potent anti-inflammatory foods of all that were tested. [7]

Additionally, in a 2015 study, researchers surmised that cinnamon could be used as a potential treatment of age-related inflammatory conditions. [8]

3. Ginger

Ginger is considered to be one of the warming Traditional Chinese Medicine herbs, commonly used to treat colds. [9] But this powerful herb is also incredible versatile and has been shown to aid in the treatment of a variety of conditions.

For example, numerous studies have shown that ginger can help to prevent and relieve nausea and vomiting. [1011] And a 2013 study confirmed that ginger oil is effective in fighting nausea and even reduced the need for anti-nausea medications post-surgery. [12] In fact, sipping on ginger tea is a great way to aid in nausea relief.

In addition, ginger is often used for other ailments, including arthritis, migraines, and even hypertension. [13] And a 2015 study even found that ginger helped reduce fasting blood sugar in people with diabetes. [14]

Interestingly, ginger also shows promise as a therapeutic agent for asthma. A study showed that ginger has the ability to relax the smooth muscle in the airway, which may help provide quick relief to those experiencing asthma attacks. [15]

4. Licorice root

This Traditional Chinese Medicine herb has cooling properties and is believed to strengthen your Qi as well as aid in detoxification. It’s also believed to support your spleen and heart. [16] It’s commonly used internally for conditions such as Addison’s disease, asthma, bronchitis, coughs, peptic ulcer, and arthritis. [17]

Licorice root is also known to aid digestion. In fact, in a 2011 study, researchers found that taking licorice root daily significantly improved indigestion in participants after 15 days and 30 days. [18]

In addition, a 2010 study revealed that, due to its anti-microbial properties, licorice root was effective in treating both fungal and bacterial infections. [19]

5. Schisandra berry

Finally, the schisandra berry has been an important Traditional Chinese Medicine herb for centuries. It’s known as the “fruit of five tastes” in Traditional Chinese Medicine because it contains all five basic flavors: salty, bitter, sweet, sour, and spicy. [20]

Schisandra berry is one of several adaptogenic herbs, which are non-toxic plants that are commonly used in Traditional Chinese Medicine because of their ability to help the body manage mental and physical stress. Plus they help support the immune system.

According to a 2014 study, schisandra berry can actually benefit those with osteoporosis. Researchers found that the herb was able to significantly increase bone mineral density. [21] Moreover, studies have shown that this Traditional Chinese Medicine herb can benefit many areas of health—from aiding cognitive function to supporting adrenal health to even suppressing tumor growth, making it an incredible versatile natural treatment option.

Vagus Nerve Function: How It Calms You + 5 Ways to Stimulate It

How does a trip to vagus sound? No, I didn’t misspell it … I’m talking about your body’s vagus nerve—which you can view as the heart of your parasympathetic nervous system (the system responsible for helping you to de-stress and unwind after a fight-or-flight response). And since chronic stress is linked to so many of our modern illnesses and diseases, you can probably guess why you need to know about your vagus nerve function.

So, let’s take a closer look at the vagus nerve function and review what it does. I’ll also explain what happens when this nerve is stimulated and how that supports your body’s stress response and overall health.

 

All About the Vagus Nerve Function

So, what is the vagus nerve? The vagus nerve is one of the 12 cranial nerves in your body. It’s by far the longest and most complex cranial nerve, often referred to as the tenth cranial nerve. Now, it’s important to note that the vagus nerve is actually split into two nerves—one on each side of your body. It starts at your brain stem and runs down through your chest and into your abdomen.

Now, what does the vagus nerve do? In terms of vagus nerve function, this nerve is responsible for connecting your brainstem to the rest of your body, including your neck, heart, lungs, and abdomen. As such, it actually sends vital information about your major organs and body to your brain. It basically helps your brain to not only become aware of what’s happening in your body but also to monitor it.

Interestingly, the vagus nerve function also extends to being responsible for regulating your digestion, heart rate, respiratory rate, and even certain reflex actions (such as coughing, sneezing, swallowing, and even vomiting).

Due to its important role, this nerve is also involved in the “digest and rest” portion of your central nervous system, making it essential in controlling symptoms of anxiety, depression, insomnia, memory, and even poor attention. Now, when it comes to the vagus nerve, researchers pay close attention to its tone, also known as its level of activity or stimulation.

They’ve found that when vagus nerve function is suppressed, or the nerve has low tone (which is what happens during times of chronic stress), you tend to have more psychological concerns and mood disorders, such as depression, anxiety, and insomnia.

In addition, studies have shown that low vagal tone can result in digestive difficulties, inflammation, and even obesity! How? Well, one of the most critical functions of the vagus nerve is its ability to transmit hunger and satiety signals.

A2016 review stated that chronic consumption of high-calorie foods reduces the sensitivity of the neurons in the vagus nerve. The researchers revealed that this disruption to vagus nerve function can drive instances overeating and obesity.

Now, conversely, a stimulated vagus nerve (one that has high tone) has been shown to improve symptoms of anxiety disorders and inflammatory disorders, such as rheumatoid arthritis and diabetes. It also aids your digestion and absorption of nutrients, lowers risk of heart disease, aids in toxin removal, supports kidney function, and evens supports the mind-body connection!

In fact, a 2013 study revealed that greater vagal tone was linked to better physical and mental health. Additionally, studies have shown that stimulating the vagus nerve lowers inflammation by suppressing the production of proinflammatory cytokines (markers of internal inflammation).

Furthermore, studies have shown that vagus nerve stimulation is a promising ancillary treatment for previously treatment-resistant depression, PTSD, and inflammatory bowel disease! Researchers stated that there is evidence that this is linked to the beneficial effect that good gut bacteria have on the nerve.

As you can see, it’s important to have high vagal tone, but exactly how do you do that? Let’s take a closer look at natural ways you can stimulate the vagus nerve.

5 Natural Ways to Stimulate the Vagus Nerve

Traditionally, conventional medicine states that the vagus nerve must be stimulated electronically via a device inserted into your body. But it can actually be stimulated in a more natural, safer ways. Here are a few of the scientifically-proven natural ways you stimulate and help tone your vagus nerve.

1. Spend time meditating.

If you aren’t familiar with meditation, it’s the art and practice of training your mind to be aware and in the present moment. Interestingly, meditation has been shown to instantly calm both your body and mind. [7] And this is largely thanks to the vagus nerve.

According to the same 2013 study from above, practicing meditation resulted in greater vagal tone and increased positive emotions.

2. Get moving.

Believe it or not, simply just performing some light exercise can be enough to stimulate the vagus nerve.

A 2019 study revealed that moderate exercise actually activates the vagus nerve, which induces the release of dopamine and actually reduces systemic inflammation. Additionally, a 2012 study showed that yoga was able to correct underactivity of the parasympathetic nervous system due, in part, through stimulating the vagus nerve.

If you’re looking for tips on beneficial yoga moves, check out these yoga poses that also help promote digestion.

3. Take a cold shower.

While you may think of taking a cold shower as a stressful experience, research shows the opposite may be true.

According to a 2018 study, cold stimulation on your neck can actually strengthen vagal tone and ultimately lower heart rate. In addition, another study revealed that regularly exposing yourself to cold temperatures can stimulate the vagas nerve, which will help decrease the fight-or-flight response and activate parasympathetic activity.

Now, the idea of taking a cold shower probably isn’t very appealing. So, take a shower as you normally would and make the water colder for the last minute or two.

4. Try intermittent fasting.

Intermittent fasting is known to provide many health benefits, from improving your memory to fighting inflammation to supporting your body’s stress response. It’s even been shown to improve your resting heart rate and heart rate variability, which is an indicator of vagus nerve stimulation.

Accordingly, one animal study revealed that fasting activated the vagus nerve, which aids in the nervous system’s response to threating stimuli.

5. Sing or hum a tune.

Finally, if you’re looking for a simple way to simulate the vagus nerve, look no further than your own voice. That’s right—research has shown that simply singing or humming can simulate the vagus nerve and improve vagal tone. And this is possible because your vocal chords are actually connected to your vagus nerve!

To confirm this, researchers studied how singing impacts heart rate variability (an indicator of high vagal tone) and found that song structure, respiration, and heart rate were connected.

So, the next time you’re feeling stressed, begin singing or humming a favorite tune to help stimulate your vagus nerve and promote calmness.

What's So Sweet About Sweet Potatoes? 7 Nutritional Benefits of Sweet Potatoes

When it comes to plant-based complex carbohydrates, sweet potatoes are my go-to food! They’re filling with a slightly sweet flavor that I absolutely adore. But, it’s not just the taste I love—the many nutritional benefits of sweet potatoes are what truly make them one of my favorite foods. There’s nothing like eating a delicious meal and knowing that you’re providing your body with quality nutrients that support optimal health. Plus, it’s so easy to bake or roast a sweet potato or even add it to one of your favorite recipes, making it a really versatile food.

Let’s take a closer look at the many nutritional benefits of sweet potatoes as well as some of the many ways you can enjoy eating them! If they aren’t already, I’m sure sweet potatoes will become one of your favorite foods in no time!

 

7 Nutritional Benefits of Sweet Potatoes

The nutritional benefits of sweet potatoes stem from the fact that they’re loaded with many vitamins and minerals—from vitamins A and C to magnesium and potassium. They’re even rich in fiber and many health-promoting antioxidants. Here are seven of the amazing nutritional benefits of sweet potatoes, some of which may surprise you!

1. Help strengthen your immune system

Sweet potatoes are a great source of beta-carotene, an antioxidant known as a carotenoid that produces a red/orange pigment in certain plant-based foods. While beta-carotene is commonly associated with carrots, it actually exists in great abundance in sweet potatoes.

Amazingly, beta-carotene is a precursor for vitamin A, meaning your liver actually converts any beta-carotene you consume into this health-promoting vitamin. And, when this happens, it helps your body to both prevent and fight infections.

In fact, studies have shown that a vitamin A deficiency actually impairs your natural immunity by blocking the normal regeneration of your mucosal barriers. [1] This makes adequate beta-carotene consumption vital because mucosal barriers actually keep the bacteria and toxins in your environment from regularly entering into your body. So, anytime you have an inadequate intestinal mucosal barrier, it allows more microbes and toxins to enter your body, which can result in inflammation. [2]

Moreover, these barriers allow water, nutrients, and other health-promoting factors to enter into your body, keeping you healthy and your immune system strong.

2. Can help manage stress and anxiety

When it comes to the nutritional benefits of sweet potatoes, their ability to help manage stress and anxiety is one not to be missed. You see, one sweet potato contains 30 to 35 mg of magnesium.

Why does this matter? Well, magnesium is very involved in producing the very neurotransmitters that help to keep you calm. In addition, magnesium is also involved in producing cortisol, which is the hormone produced to help your body adapt during times of stress. So, when you aren’t getting enough magnesium, you’re at an increased risk of higher stress levels as well as more bouts of anxiety.

In fact, one animal study revealed that a magnesium deficiency could increase both anxiety and depression. [3] And a 2014 study revealed that lower levels of antioxidants were linked to symptoms of anxiety. [4]

Give their magnesium and antioxidant content, it’s easy to see how regularly consuming sweet potatoes could support your body’s stress response and help to fight anxiety.

3. Support digestion

Sweet potatoes are also a great source of soluble fiber, which supports a healthy gut.

As you now know, the state of your gut is linked to many other health conditions, making gut health critical for overall health. In fact, a 2018  study revealed that purple sweet potatoes actually act as a prebiotic by promoting the growth and development of healthy gut bacteria. [5]

Additionally, a 2020 study showed that the dietary fiber in sweet potatoes significantly increased the amount of Bifidobacterium and Lactobacillus (good bacteria) in the microbiome. These bacteria are known to improve digestion as well as absorption in the gastrointestinal tract. [6]

4. May help improve memory

Just as the antioxidant beta-carotene provides plant-based foods with a red or orange color, the antioxidant anthocyanin provides them with a purple color. But the difference here is that foods known to contain anthocyanin are typically referred to as “superfoods,” thanks to this antioxidant’s many health properties.

In fact, anthocyanin, which is famously found in high amounts in purple sweet potatoes, has been shown to enhance memory as well as boost focus in animal studies. [7] Furthermore, research has shown that consuming foods rich in anthocyanin boosts focus and attention in children.

According to a 2012 study, children aged 7 to 9 consumed either a control beverage (with no anthocyanin), a beverage containing a moderate amount of anthocyanin, or a beverage containing a fairly large amount of anthocyanin. The children were then asked to complete certain memory- and focus-related tasks. The researchers found that memory, attention, and focus were all significantly better in the children who consumed the anthocyanin beverage than those who drank the control beverage. [8]

5. Support eye health

When it comes to the nutritional benefits of sweet potatoes, we can’t ignore their ability to support eye health. And, once again, we can largely link this back to its vitamin A content and beta-carotene content.

Did you know that vitamin A has been shown to help soothe eye inflammation? One study followed 12 patients who had a type of eye inflammation known as superior limbic keratoconjunctivitis. The researchers found that using eye drops containing vitamin A were found to be an effective treatment in 10 of the 12 patients. [9]

Additionally, a 2019 study revealed that vitamin A consumption improved the quality of tears in patients with dry eye, exhibiting how helpful vitamin A can be for eye health. [10]

6. Contain anti-inflammatory properties

Sweet potatoes are also known to fight inflammation—once again due to its vitamin A and beta-carotene content. In fact, studies have shown that having adequate levels of vitamin A can actually help fight inflammation by keeping your immune system from overacting.

According to a 2017 review, both clinical trials and animal studies have shown that consuming carotenoids reduced systemic inflammation in young infants as well as neuroinflammation in people with brain injuries. [11]

Furthermore, the researchers stated that consuming vitamin A, in select cases, could improve inflammation. They also surmised that vitamin A’s positive effects on both the immune system and the integrity of epithelial tissue (the protective tissue surrounding your organs and blood vessels) are the main mechanisms in preventing disease.

7. Support healthy blood sugar levels

Finally, the last of the nutritional benefits of sweet potatoes is the ability to fight diabetes by supporting healthy blood sugar levels.

In 2008 study, researchers conducted a trial on 27 patients with type 2 diabetes. They found that consuming an extract of sweet potatoes improved the participants’ insulin sensitivity, fasting glucose, hemoglobin, and triglycerides. [12]

Also, a 2011 study revealed that consuming sweet potatoes helped to manage blood sugar levels, especially compared to white potatoes. The researchers stated that due to their ability to minimize post-meal blood sugar spikes, sweet potatoes could aid in managing type 2 diabetes. [13]
