Your gut does more than digest food — it may also play an important role in mood, memory, mental clarity, and overall brain health as you age.

The Second Brain is a practical and encouraging guide for older adults who want to understand the fascinating connection between gut health and cognitive wellbeing. Written in a clear, accessible style, this book explores the gut-brain axis, the microbiome, and the everyday habits that may influence how the body and brain communicate.

Inside, you'll discover how digestion, inflammation, stress, sleep, movement, and food choices can all affect the gut-brain connection. Rather than overwhelming readers with complex science, this book breaks the research down into simple, realistic strategies that can support better gut health, emotional balance, and long-term cognitive wellbeing.

This book will help you:

Understand the connection between gut health, mood, and brain function
Learn what the gut-brain axis is and why it matters after 60
Discover how the microbiome may influence mental clarity and emotional wellbeing
Explore gut-supportive foods and daily habits

Whether you want to feel clearer, support your mood, improve your daily habits, or better understand how your digestive health connects to brain health, The Second Brain gives you a calm, practical place to begin.

A clear and supportive guide for anyone ready to nourish the gut, support the mind, and age with greater confidence.
