The Microbiome-Wellness Connection

You must know by now that our bodies are home to trillions of microorganisms – bacteria, viruses and other microbes. Together they form what’s called the microbiome. From the perspective of a former microbiologist, it’s both a beautiful word and a spectacular concept.

Far from being simple passengers, these little guys form a complex community that is essential to our health, influencing everything from our digestive processes to our mental and dental health.

Microbes run the world, in nature and in each of us. Research is only beginning to understand the impact of the microbiome on wellness. The more we learn, the more we realize that nurturing our microbiome is key to maintaining optimal health.

What Is a Microbiome?

The microbiome includes all of the microorganisms living in and on our bodies:

• Bacteria – the most abundant and well-studied.
• Viruses – including bacteriophages that infect bacteria.
• Fungi – various species of yeast.
• Protozoans – single-celled organisms that can be commensal or parasitic.

The largest and most diverse populations are found in the gut, skin, mouth, respiratory tract, and urogenital system.

They influence many aspects of our health.

Digestive Health

The microbiome plays the most obvious role in our digestive system. Certain bacteria in our gut can break down complex carbohydrates, such as dietary fiber, that our bodies can’t digest on their own.

It also produces essential vitamins, particularly vitamin K and several B vitamins, which our bodies can’t synthesize on their own.

Immune Function

Our microbiome helps our immune system distinguish between harmful pathogens and beneficial or harmless microorganisms, and responds accordingly by producing compounds that help regulate our immune response.

The gut microbiome, in particular, is closely tied to immune function. Did you know your gut makes up the largest component of your immune system? An estimated 70-80% of our immune cells reside in the gut.

Additionally, beneficial microbes compete with potentially pathogenic organisms for resources and space, forming a first line of defense against infections.

Mental Health and Mood

The connection between the microbiome and mental health is often called the gut-brain axis.

Studies have shown that the composition of our gut microbiome can affect stress responses, anxiety levels, and even cognitive function.

Have you ever tried a diet with regular consumption of fermented foods? If so, you’ll probably have noticed a boost in energy and mood. It does, however, depend on what else you’re consuming.

Fun fact: The gut microbiome produces about 90% of the body’s serotonin, a key mood regulator.

Another fun fact: Research is currently exploring the link between the microbiome and neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Weight Management

Different compositions of gut bacteria are often associated with extreme weight issues, too much and too little. Our microbiome can influence how we store fat and may even impact our food cravings and appetite.

For example, we’ve learned that certain gut bacteria affect the production of hormones that regulate hunger and satiety. Understanding these connections more thoroughly could lead to new approaches to addressing both obesity and metabolic disorders.

Skin Health

The microbes on our skin form a protective barrier against potentially harmful organisms. They also help maintain the skin’s slightly acidic pH, which is inhospitable to many pathogens.

The skin microbiome also influences hydration levels and may affect skin conditions like acne, eczema, and psoriasis.

Dental Health

The oral microbiome plays an enormous role in dental health by maintaining a delicate balance in the mouth. It affects tooth decay, gum health, and overall oral hygiene.

Bacteria are responsible for protecting against harmful pathogens and maintaining proper pH levels. An imbalance in either or both can lead to issues like cavities and gum disease.

In addition, growing research suggests a substantial link between oral microbiome imbalance and chronic diseases like cardiovascular disease and diabetes. Understanding this complicated relationship will open a whole new level of dental care.

As research progresses, we’ll uncover even more ways our microbial community influences our well-being. One thing is already crystal clear: the microbial world demands our respect.

Supporting Your Microbiome

Several factors influence your microbiome balance, including diet, antibiotics, medications, stress, environment, and lifestyle choices.

It’s important to make mindful choices. Here are some great options.

• Consume probiotic-rich foods like yogurt, kefir, and sauerkraut.
• Eat prebiotic foods like garlic, onions, leeks and asparagus.
• Increase fiber intake through fruits, vegetables, and whole grains.
• Limit processed foods and artificial sweeteners.
• Practice stress management techniques.
• Maintain regular physical exercise.
• Prioritize quality sleep.

Good ideas in many respects, right?

It’s also crucial to avoid unnecessary antibiotics, only use them when prescribed and necessary, and complete the entire course when prescribed. If you are prescribed antibiotics, it becomes even more important to help repopulate a healthy microbiome by focusing on eating nutritious whole foods and getting plenty of fiber in your diet.

The future of microbiome research is exciting! Whatever it holds however, paying attention to these tiny guys now can yield big rewards for our current health.
