Gut Health, Mood & Cognitive Function
The Second Brain
Enhancing Cognitive Function Through Gut Health Strategies for Older Adults
A warm, practical guide to the gut-brain connection and how supporting gut health may help improve cognitive function, mood, and mental sharpness after 60.
About the Book
The Second Brain introduces readers to the powerful and increasingly important science of the gut-brain axis. Anne Fielding explains how the microbiome communicates with the central nervous system and why this connection matters for memory, cognition, mood, and overall mental wellbeing in later life.
This book helps readers understand the relationship between digestion, inflammation, emotional balance, and brain health in a way that feels clear rather than overwhelming. It then turns that science into practical action, showing how diet, movement, stress management, and supportive habits can help nurture a healthier gut and, in turn, a healthier mind.
Encouraging and accessible, The Second Brain is an excellent guide for older adults who want to understand the bigger picture of cognitive wellbeing and take practical steps toward feeling sharper and steadier.
