The Link Between Gut Health and Mood

The old saying “trust your gut” may be more accurate than we realize. Research shows that gut health is closely connected to mental health. This is because the gut and brain communicate through what’s called the gut-brain axis.

Your digestive system is home to trillions of bacteria, known as the gut microbiome. These microbes help digest food, produce vitamins, and even influence mood by affecting neurotransmitters such as serotonin—the “feel-good” chemical. In fact, about 90% of serotonin is produced in the gut.

When the balance of good and bad bacteria is disrupted, it can contribute to issues like anxiety, depression, and poor focus. Processed foods, high sugar intake, and chronic stress can all harm gut health.

Supporting gut health doesn’t have to be complicated. Eating more fiber, fermented foods like yogurt or sauerkraut, and reducing processed foods can help restore balance. Probiotics and prebiotics may also support a healthier microbiome.

Taking care of your gut is not just about digestion—it’s about boosting mood, focus, and overall well-being.
