What is a gut microbiome and why should you care?

A microbiome is a community of more then 100 trillion microorganisms that live in our body. This is about 10 times more cells than the number of human cells in the body!

The human microbiome lives in many different parts of the body, including the skin, mouth, gut, vagina, and respiratory tract. It varies from person to person and from body site to body site.

Why is our microbiome important for us?

One of the key roles is that it helps to digest food, produce vitamins, protect against pathogens, and regulate the immune system. Disruption of the microbiome can cause a number of health conditions, including obesity, allergies, and some autoimmune diseases.

Research on the human microbiome is still in its early stages, but many of us have already experienced how microorganisms in our gut communicate with the rest of our body. Examples could be digestive issues as a response to stres. Have you ever felt butterflies in your stomach when being in love?

How can we get a healthy microbiome?

  • Eating a healthy diet: A diet rich in fruits, vegetables, and whole grains can help to promote the growth of beneficial bacteria in the gut.
  • Taking probiotics: Probiotics are live bacteria that can be taken as supplements or found in fermented foods such as yogurt and kefir. They can help to restore the balance of bacteria in the gut.
  • Avoiding antibiotics: Antibiotics can kill beneficial bacteria as well as harmful bacteria. When possible, it is best to avoid antibiotics unless they are absolutely necessary.
  • Managing stress: Stress can disrupt the microbiome. Finding healthy ways to manage stress, such as exercise and meditation, can help to keep the microbiome healthy.


  • Improved digestion: The microbiome helps to break down food and absorb nutrients.
  • Stronger immune system: The microbiome helps to protect the body against pathogens.
  • Reduced risk of allergies and asthma: The microbiome helps to regulate the immune system and may reduce the risk of allergies and asthma.
  • Improved mental health: The microbiome may play a role in mental health conditions such as depression and anxiety.
  • Protection against cancer: The microbiome may help to protect against cancer by suppressing the growth of tumor cells.


The human microbiome is a complex and fascinating system that is still being studied. However, we are beginning to understand the important role that it plays in human health. By taking steps to support a healthy microbiome, we can improve our overall health and well-being.
