Remember those “butterflies” you felt in your stomach before giving a big presentation? Or how you might trust your gut when making a decision? Increasingly, science says your brain and gut are in constant communication with each other. Researchers refer to this connection as the gut-brain axis, and it’s one of the most important junctures in your body.
In many ways, your gut and your brain are the best of friends. These organs work with each other to influence a variety of health components including mood, stress, digestion, cognitive function and immunity.
How? Well, your stomach houses trillions of bacteria that make up your gut microbiome. These bacteria are constantly communicating with your brain through your nervous and immune systems. They help produce neurotransmitters, chemical messengers that influence mood, digestion and how your body processes sensory information.
When your gut microbiome wobbles out of balance, the effects ripple throughout your entire body. Research shows that an unhealthy gut has been linked to anxiety, depression and a weakened immune system.
Luckily, supporting your gut health doesn’t require a complete lifestyle overhaul. Start by including more fiber-rich foods in your diet like fruits, vegetables and whole grains. These act as fuel for your good bacteria. To go the extra mile, add fermented foods that are high in probiotics like yogurt, kimchi or sauerkraut.
Beyond diet, prioritize seven to nine hours of sleep each night. Manage your stress as best as you can, and stay hydrated — it’s critical for proper digestion and a diverse microbiome. Lastly, get regular exercise. An active body means an active gut.
