Did you know your mind and gut are connected? Having “butterflies” in your stomach when you are nervous or having an upset stomach when you are stressed is proof that our brain and gut are talking to each other.
But How?
Your digestive tract contains about 100 million neurons, known as the enteric nervous system, earning it the nickname “second brain.” The vagus nerve connects the brain and gut, allowing two-way communication, known as the gut-brain axis. Your gut microbiota (trillions of microbes that live in your gut) also join the conversation by producing over 30 neurotransmitters, including about 95% of your body’s serotonin (your happy hormone), which influences mood and well-being.
Why does the connection matter?
So why does this connection matter? You might be surprised to know that most signals along the vagus nerve actually travel from your gut to your brain (not the other way around), meaning your gut can strongly influence your mood, stress levels, and overall mental well-being. When the balance of gut bacteria is disrupted, it can trigger immune overreactions, inflammation, and symptoms that affect both body and mind.
Happy Gut, Healthy You
What we eat is one of the fastest and easiest ways to influence the gut microbiota. By giving your gut microbiota the nutrition it needs to flourish, it will help take care of you.
While the research is still relatively in its infancy, there are a few things we can confidently recommend to promote digestive health:
- Getting adequate fibre. Health Canada states that women need 25 grams of fibre per day and men need 38 grams of fibre per day. Unfortunately, Canadians are only getting about half that much!
- Focusing on dietary variety – especially those plant-based foods
- Reducing excess intake of red & processed meats
- Reducing excess intake of ultra-processed foods that are often high in sugar and fat, and low in nutrients & fibre
- Studies have shown that psychologically based approaches lead to greater improvement in digestive symptoms compared with only conventional medical treatment.
- Techniques such as meditation, yoga, cognitive behavioral therapy, gut-directed relaxation training, and exercising are all proven therapies to help you better deal with stress levels and improve mood, and consequently symptoms of digestive discomfort.
- Include probiotics and fermented foods with live cultures to help support a healthy microbiome.
The Bottom Line
Your gut and brain are in constant conversation, shaping how you feel both physically and emotionally. By nourishing your gut with a balanced diet, supporting it with probiotics and healthy lifestyle habits, and managing stress through mind–body practices, you can strengthen this powerful connection. A healthy gut really can mean a healthier, happier you!
