Did you know your gut is often called your “second brain”? With roughly 100 million neurons, it communicates directly with your central nervous system through the gut-brain axis. This two-way connection means your gut health can influence your mood, focus, and even long-term brain health.
The key player is your gut microbiome, a community of trillions of microbes. These tiny organisms help digest food, produce mood-regulating neurotransmitters like serotonin, and even impact cognitive function. When this ecosystem is out of balance, it can contribute to anxiety, depression, and other mental health challenges. Emerging research also links gut health to neurodegenerative disorders such as Parkinson’s and Alzheimer’s, showing just how far-reaching the gut’s influence can be.
The good news? There are simple ways to support both your gut and your brain:
Your gut isn’t just about digestion - it’s central to your mental and neurological wellbeing. By feeding your microbiome with healthy foods and mindful habits, you’re giving both your brain and your body the support they need to thrive.
