SESSION ABSTRACT: Feed Your Brain: How Your Gut Shapes Memory, Mood, and Mental Sharpness
Dr Rye’s research examines the gut–brain axis as a critical driver of cognitive health, particularly in adults over 50. Emerging science shows that the gut microbiome plays a central role in regulating inflammation, neurotransmitter production, and neural signalling, directly influencing memory, mood, and resilience to cognitive decline. By focusing on diet, microbial diversity, and evidence-based lifestyle interventions, this work highlights how optimising gut health can help preserve brain function and support lifelong mental sharpness. The findings translate complex science into practical strategies that empower individuals to enhance cognitive vitality, sustain curiosity, and maintain meaningful engagement with the world as they age.
Dates: Tuesday 22nd September
Time & format: The workshop will start at 10am, with a coffee and tea break followed by a lively facilitated discussion to answer all your curious questions. The course will finish at 12pm each week.
Location: We are delighted to be hosting at The Common Room, 227 Heretaunga Street East, Hastings 4122
