The Importance of a Healthy Gut Microbiome

Updated: 5 days ago


Recently, there has been a lot of talk about optimizing gut health and the gut microbiome. But what exactly is the gut microbiome? And how do you support a healthy gut microbiome?


What is the Gut Microbiome?


The gut microbiome is a vast collection of different bacteria and other microscopic life forms that naturally live within our digestive system. There are trillions of these microbial organisms within us all that we can collectively call our gut microbiome, also known as our gut flora. In fact, there are more of these microbial cells in our bodies than we have human cells (40 trillion vs 30 trillion).

These microbes aren’t living here by random - we have evolved to have a mutually beneficial relationship with the microscopic organisms living in a healthy gut microbiome. These healthy gut flora directly impact our health, and when they fall out of balance, they can lead to various health complications.


The gut microbiome and health

Many people hear the word “bacteria” and automatically believe that they are unhealthy. However, this couldn’t be more false!


Much of the bacteria living within us is actually beneficial, whether it is by helping to prevent opportunistic infections and overgrowths or by breaking down and extracting nutrients from our food, or by producing vitamins and short-chain fatty acids for our bodies to use.


Think of the gut microbiome as a fingerprint; each of us has a uniquely composed microbiome. Science is now learning more about how these differences impact our health and our lives.


There are about one thousand different species of bacteria that live within our guts, each with a different role to play. Some species can benefit our health, while others can negatively impact our health.


The composition of the gut microbiome can impact many things, including:

  • Overall digestive health

  • Nutrient absorption

  • Ability to gain or lose weight

  • Immune function

  • Brain health and mood

  • Heart health

  • Blood sugar control and diabetes

  • Bone and joint health

  • Inflammation


An unhealthy microbiome marked by dysbiosis (imbalance) and high inflammation can contribute to:

  • Obesity

  • Autoimmune disorders

  • Cancer

  • Heart disease

  • Type 1 diabetes

  • Brain disorders (Alzheimer’s, dementia)

  • Infertility and complications in pregnancy

  • Mood disorders

  • Allergies and food sensitivities

  • Learning disabilities

  • Bone and joint deterioration

Gut microbiome testing with the GI-MAP

One of the best ways to assess the health of your gut microbiome is to utilize functional lab testing with the GI-MAP (Gastrointestinal Microbial Assay Plus) test. The GI-MAP is a comprehensive test that reveals your personal microbiome composition along with markers for inflammation, intestinal health, and immune function.

The analysis of your microbiome may also reveal pathogenic infection (bacteria, viruses, parasites), imbalances of bacteria (dysbiosis or overgrowths), and whether there are antibiotic-resistance genes present. Knowing the state of your digestive health is the first step to customizing a treatment protocol that will allow you to reach your health goals. Order a GI-MAP test with me to get started!


How to improve your gut microbiome

Taking care of your gut microbiome is of the utmost importance. There are many things you can do to ensure a healthy gut microbiome, including eating a healthy diet and reducing stress.


Healthy gut microbiome diet


Eating healthy is the first step to supporting your health and your gut microbiome. Consuming anti-inflammatory foods while cutting out inflammatory foods is the key to keeping your gut flora healthy.


Make sure to load up on fresh vegetables and fruits along with herbs and spices, which are packed with antioxidants and other gut-healing nutrients.


Probiotic-rich food can also help to populate your digestive tract with healthy bacteria:

  • Yogurt

  • Kombucha

  • Kefir

  • Sauerkraut

  • Fermented veggies


Also focus on consuming prebiotics, which are indigestible fibers that feed your healthy flora:

  • Garlic

  • Onions

  • Leeks

  • Tomatoes

  • Asparagus

  • Jerusalem artichokes


Inflammatory foods to limit or avoid include:

  • Refined vegetable oils (corn, canola, soybean)

  • Refined carbs and processed grains

  • Foods and beverages with added sugars

  • Unhealthy trans fats and hydrogenated oils

  • Processed foods

  • Foods/ingredients you are allergic or sensitive to

  • Unfiltered water


For more guided nutrition assistance, schedule an appointment with me to get individualized recommendations based on your GI-MAP test and health history.


Reduce stress to improve your microbiome

Chronic stress negatively impacts our health in many ways. Stress can impact every step of digestion and can potentially lead to dysbiosis and overgrowths within our gut microbiome. This can lead to digestive symptoms, decreased immune function, and increased inflammation throughout the body, which can result in further health complications down the line.


Some ways to tackle stress within your daily life include:

  • Making time for exercise/movement throughout the day

  • Meditation

  • Deep breathing exercises

  • Yoga and stretching

  • Prioritizing self-care

  • Getting enough good quality sleep

  • Setting boundaries and learning how to say “no”

  • Finding time for hobbies and relationships with friends and family


The bottom line

Maintaining a healthy gut microbiome is the key to long-lasting health. If you’ve heard the quote “all disease starts in the gut” - you now understand how and why.


Our gut microbiome is responsible for regulating or supporting many functions within our bodies, and keeping the good gut bugs in balance can help to prevent the development of chronic disease.


If you have symptoms of digestive distress, poor immunity, mood disorders, or just want to know more about the state of your digestive health and microbiome, order a GI-MAP test through me so I can help design your treatment protocol based on your individual results.
