Though it sounds odd, Bianca Hayes is dissecting the data to show how gut health affects mental well-being.
Often referred to as the “second brain,” the gut-brain axis, a sophisticated network of nerves, hormones, and biochemical signals directly connects with the brain. New studies point to a dysbiosis—an imbalance in gut flora—as a possible cause of mood disorders including anxiety and sadness.
About 90% of the body’s serotonin, a neurotransmitter vital for controlling mood, sleep, and hunger, Bianca says comes from the stomach. Poor food, persistent stress, or antibiotic abuse can all impact gut health and cause disruptions in serotonin synthesis, therefore affecting emotional and cognitive processes.
To support a healthy gut-brain connection, Bianca recommends:
- Prioritizing Probiotics & Prebiotics: Fermented foods (like yogurt, kimchi, and kefir) and fiber-rich plants (such as bananas, garlic, and oats) nourish beneficial gut bacteria.
- Reducing Inflammatory Foods: Processed sugars, artificial additives, and excessive alcohol can harm gut flora.
- Managing Stress: Chronic stress weakens the gut lining, so mindfulness practices and adequate sleep are essential.
Bianca’s observation? Usually, a happy gut corresponds with a happy mind. Taking care of your microbiome helps you invest in mental resilience rather than only improve digestion.
