The gut-brain axis is two-way communication between the central nervous system (the nervous system of the brain and spinal cord) and the enteric nervous system (the nervous system in the gut). Have you ever had a ‘gut feeling’ or were in a stressful situation only to feel like someone punched you in the gut? These are perfect examples of this direct connection between the gut and brain.
The balance of bacteria in our gut, called the microbiota, directly impacts this gut-brain connection. Bacteria in our guts interact with cells in our intestinal nervous system, directly interacting and sending messages to our central nervous system in the brain. These bacteria also have the power to activate the vagus nerve, and chronic activation of the vagus nerve contributes to anxiety and depression. These bacteria can also influence the hypothalamic-pituitary-adrenal axis, which controls the body’s response to stress. Having the right balance of bacteria in your gut is crucial for harmony in mind and body.
To add to the guts impact, bacteria in the gut induce the production of serotonin. We make a whopping 95% of our serotonin in the gut! Serotonin is a good feeling neurotransmitter that helps us enjoy life. The balance of bacteria in our gut is impacted by stress, so if you’re stressed, your gut is more likely to be imbalanced, which affects brain health even more, and there goes your cycle.
So what do you do to build a healthy gut and promote mental and physical health? Check out these two main nutrient tips below.
Pack in the Prebiotic Fiber
Foods high in prebiotic fiber help feed good bacteria, helping them thrive. Research in The American Journal of Clinical Nutrition found that low fiber diets are directly linked to depression while high fiber diets may reduce symptoms of depression. Including high prebiotic fiber foods in your daily diet will help ensure you’re providing your gut with what it needs for optimal health. Check out the list below for some excellent sources of high prebiotic fiber foods.

Probiotics may reduce inflammation, anxiety, and stress. Healthy gut bacteria produce short-chain triglyceride butyrate, which is neuroprotective. This means butyrate help protect nerve cells against damage, promoting seamless functioning. Bacteria in the large intestine ferment fiber and produce these short-chain fatty acids. Ingesting probiotics may help replenish bacteria in your gut and encourage butyrate production. Regularly including foods with probiotics in your diet can help keep your gut bacteria balanced. Excellent sources of probiotics include:
- Yogurt with active cultures
