One of the most remarkable interactions that happens in our bodies is the brain–gut connection. The communication between these two vital organs can impact everything from our physical to mental/emotional health and our overall well-being. Today I am going to explain the science between the brain-gut connection in a digestible way (see what I did there) and how we can make conscious choices to help support the communication between the two to improve our health.

The Science Behind the Brain-Gut Connection:
Did you know that your gut is often referred to as your “second brain?” It’s true! Your gut has a community of neurons, known as the enteric nervous system (ENS) that communicates back and forth with your brain via your vagus nerve. This forms the intricate brain-gut axis.
The brain-gut axis influences so many of our bodily functions, from our digestion to our mood regulation, shaping our overall well-being. Here are some examples of this connection at work: have you ever felt a surge of anxiety before a big presentation and then experienced a tummy ache? Or have a “gut feeling” guiding your choices? That’s the brain and gut working together, translating emotions into physical sensations.
But, the impact of the brain-gut connection extends beyond momentary sensations. Recent studies have shown links between the brain-gut axis and various aspects of health, including mental well-being, immune function, and gastrointestinal disorders. Conditions like anxiety, depression, and irritable bowel syndrome (IBS) are now recognized as manifested disruptions of the intricate system that is the brain-gut axis.
Optimizing the Brain-Gut Connection to Promote Better Health
By now you’re probably like, “okay, I get it, this is important. But what do we do about it?” You’re in luck, optimizing the brain-gut connection to promote better health is just a matter of making conscious decisions around our diets and stress management.
Nurturing our gut microbiome (the diverse community of bacteria in our digestive tract) is step one. We want to incorporate gut-friendly foods rich in probiotics, prebiotics, and fiber to cultivate a flourishing ecosystem in our guts to support optimal digestion and immune function. Probiotics like kombucha, fermented vegetables (sauerkraut and kimchi), kefir and yogurt introduce live cultures into your gut, promoting diversity and resilience within the microbiome. Prebiotics are non-digestible fibers that serve as food for the beneficial bacteria in your gut, stimulating their growth and activity (think garlic, onions, leeks, and bananas). A diet rich in fiber is essential for gut health, it promotes regular bowel movements, supports digestion, and provides fuel for beneficial gut bacteria. Opting for foods like apples, berries, broccoli, spinach, oats, lentils, almonds and chia seeds will help increase your fiber intake. And bone broth, one of my favorite gut healing tools, is rich in collagen, amino acids and minerals. Bone broth helps to heal and seal the gut lining, preventing leaky gut syndrome and supports overall digestive health.
In addition to our diet, stress management plays a pivotal role in supporting a healthy brain-gut axis. Incorporating mindfulness practices such as mediation and deep breathing can soothe the nervous system, alleviating stress. Check out this blog post on additional mindfulness practices. Additionally, lifestyle factors like adequate sleep, regular exercise, and hydration also contribute to a healthy gut-brain axis.
Lastly, the Stress, Mood, and Metabolism functional medicine test could help to give you a better understanding of where you currently are and a roadmap to help you optimize your gut-brain connection. If you’re interested in lab testing please reach out to me, I’d love to help you understand where you’re at and help you to better optimize your brain-gut connection!
