Understanding the connection between your gut health and your brain health.
Have you ever experienced butterflies in your stomach or abdominal pain when you’re stressed? The answer is likely, yes, and it’s a direct result of the communication between our gut and our brain. But how do they connect? And what impact can it have on your health and wellbeing? Let’s find out!
Your gut — or digestive tract — is more complex than you think. Besides having many parts — the mouth, throat, esophagus, stomach, small and large intestines, rectum, and anus — it’s also home to our enteric nervous system (ENS). This is often referred to as our “second brain.”1 Our second brain communicates with the brain in our skull and can impact not only our physical health, but our mental health, too. In fact, the gut contains 90% of our body’s serotonin receptors. These receptors influence many of our biological and neurological processes like mood and appetite.2
Physically, your gut and brain are connected by the vagus nerve. This is one of 12 cranial nerves in the body that control anything from movement of muscles and glands to things like taste and smell. Some cranial nerves control one or the other, sensory or movement. The vagus nerve controls both, with one of its main functions being to send information from your gut to your brain. This pathway is called the gut-brain axis and it is how hormones and other neurotransmitters send messages chemically.3
While your second brain won’t help you write your next great best-seller, it will control things like your digestion. In fact, according to Jay Pasricha, MD, director of the Johns Hopkins Center for Neurogastroenterology, its main role is digestion, “from swallowing to the release of enzymes that break down food to the control of blood flow that helps with nutrient absorption to elimination.” It does this through the gut microbiome, a collection of bacteria, fungi, and viruses that live in your intestinal tract.
Like most things, bacteria can be good or bad. While your good bacteria work to control the bad bacteria, sometimes they can become imbalanced. This can happen when we’re stressed, sick, overweight, or maintaining a poor-quality diet. When our gut is imbalanced and inflamed for an extended period, it can put you at risk for certain physical and mental disorders, like:3
Besides adequate sleep and limiting your stress, one of the best ways to support a healthy gut is to maintain a good quality diet. This includes:2
Just remember it’s always best to check with your doctor before making diet changes if you have a diagnosed health condition.
