Gut Instinct: Understanding the Relationship Between the Gut Microbiome and the Brain

It seems like more and more people are talking about the importance of gut health. We are finally understanding the importance of gut health and how it impacts the rest of our body. Recent studies have shown that there is a strong connection between the two, indicating that the health of the gut can directly impact the health of the brain.


The gut, or gastrointestinal tract, is home to trillions of microorganisms, collectively known as the gut microbiome. These microorganisms play a crucial role in maintaining gut health by aiding in digestion, regulating the immune system, and producing vitamins and other essential nutrients.


Recent research has also revealed that the gut microbiome can communicate with the brain via the gut-brain axis. This connection involves a complex network of neurons, hormones, and immune cells that enable communication between the gut and the brain.

Studies have shown that changes in the gut microbiome can have a direct impact on brain function, including mood, behavior, and cognitive performance. For example, disruptions in the gut microbiome have been linked to conditions such as anxiety, depression, and even neurological disorders like Alzheimer’s disease.

One possible mechanism behind this connection is the production of neurotransmitters in the gut. Many of the same neurotransmitters that are produced in the brain, such as serotonin, dopamine, and GABA, are also produced in the gut. Changes in the gut microbiome can therefore affect the production of these neurotransmitters, which can in turn impact brain function and behavior. This makes sense, doesn’t it?


Additionally, the gut microbiome has been shown to play a role in the regulation of the immune system, which is closely linked to brain health. Research has shown that inflammation in the body, which can be caused by an imbalance in the gut microbiome, can lead to damage to the brain and cognitive decline.


What Can We Do?

Now that we know the importance of gut health, how can we improve our gut health and, by extension, our brain health?



Probiotics are beneficial microorganisms that live in the gut and can improve gut health in a number of ways. They help to maintain a healthy balance of bacteria in the gut, support immune function, and can even have an impact on mental health.

The gut is home to trillions of bacteria, both good and bad. When the balance of these bacteria is disrupted, it can lead to a number of health problems, including digestive issues, allergies, and autoimmune disorders. Probiotics help to maintain a healthy balance of bacteria by introducing more good bacteria into the gut.

In addition to supporting gut health, probiotics have also been shown to have a positive impact on immune function. They help to boost the immune system, making it more effective at fighting off harmful pathogens.

There is also increasing evidence that the gut-brain axis is a two-way street, meaning that the health of the gut can have an impact on mental health. Probiotics have been shown to have a positive impact on mood and cognitive function, potentially through their effects on the gut-brain axis.


Additional Strategies:

  1. Eat a healthy diet: A diet rich in whole foods, including plenty of fruits, vegetables, whole grains, and lean protein, can help to nourish the good bacteria in the gut and promote a healthy balance of bacteria.
  2. Avoid processed foods and sugar: Processed foods and sugar can disrupt the balance of bacteria in the gut, so it’s best to limit or avoid them as much as possible. There is also research showing the benefit of the keto diet on gut health, likely due to the decrease of inflammation on the keto diet.
  3. Consume fermented foods: Fermented foods, such as yogurt, kefir, sauerkraut, and kimchi, contain live cultures of beneficial bacteria that can help to improve the balance of bacteria in the gut.
  4. Manage stress: Stress can have a negative impact on the gut microbiome, so finding ways to manage stress, such as through exercise, meditation, or mindfulness, may be helpful.
  5. Avoid unnecessary antibiotics: Antibiotics can kill off both good and bad bacteria in the gut, so it’s important to avoid them unless they are truly necessary. It has been said that it can take a year for your gut to heal from just one 10 day prescription.
  6. Get enough sleep: Lack of sleep can disrupt the gut microbiome, so getting enough restful sleep each night is important for maintaining a healthy balance of bacteria in the gut.

These are just a few strategies that may help to balance your gut microbiome. It’s important to remember that everyone’s gut microbiome is unique, so what works for one person may not work for another. It may take some trial and error to find the right approach for you.


By taking steps to support our gut health, we can help to improve our brain function and overall well-being.


The connection between gut health and brain health is a complex and fascinating area of research. You do not have to have a degree to start doing your own research and taking your health into your own hands. Countless health concerns stem from poor gut health. If you take steps to focus on your gut health, you’ll be shocked at the improvements in your health as a whole – mood, weight, skin, immune, inflammation, hormone balance….so much more.



Ready to focus on your own gut health? I would love to share how I have been able to heal my own gut, which has resulted in less stress, bloat, weight loss, focus, and more. Fill out this short form here and I will be in touch!



As a mom who just went through two and a half years of cancer treatment with her child and is still very much in the trenches, I see you and I understand. We can not always pray away our anxiety. This is especially true when our anxiety is the result of serious trauma. During our daughter’s treatment, our youngest child was diagnosed with a life threatening form of epilepsy. His condition is on going and progressively gets worse. I have worked hard on ways to manage my anxiety and my response to stressful situations. The stressors in my life are not going away, so it has been imperative to find ways to manage my responses. After a few months of being intentional with a few supplements, I am happy to report that my depression has lifted and my stress response is drastically different. So much so that my husband and children are now taking the same supplement routine. Trauma like we have experienced affects the entire family. If you want more information on what we have changed for our mental health, FILL OUT THIS FORM and I will send you the information. Praying for my medical mamas, always.
