Did you know your gut is one of the major secret players in how well your brain ages?
Through the gut brain axis, your gut microbiome influences your mental clarity, mood, resilience, and even how well your brain can form new cells (yes, really).
Here’s what the science shows:
• Diverse gut bacteria → more short chain fatty acids like butyrate → improved BDNF & neurogenesis in the hippocampus. MDPI+1
• Diets rich in prebiotic fiber & live cultures (probiotics) support beneficial bacteria and help reduce inflammation that can suppress BDNF. PMC+1
• What hurts: sugar, ultra processed foods, chronic gut imbalances or antibiotic overuse.
Simple wins:
• Add one prebiotic rich food daily (onions, garlic, chicory, oats)
• Try fermented foods (yogurt, sauerkraut, kimchi)
• Move & de stress — it all supports gut diversity and brain performance.
Let’s feed your gut so your brain can thrive.
