★A work by Ainoa Navarrete Pérez, a registered dietitian-nutritionist specializing in clinical nutrition, combining clinical practice with a doctoral research background in biomedicine, with a particular focus on neurodegenerative diseases such as multiple sclerosis.
★Blending the latest scientific evidence with real-world clinical experience, this book takes you through the true mechanisms of brain aging—from inflammation and oxidative stress to gut microbiota health—in a clear, rigorous, and accessible way.
★This book thoroughly deconstructs how diet influences cognitive function by modulating inflammatory responses, oxidative damage, and the balance of gut microbiota, and helps you fundamentally rebuild your relationship with food.

Time is unstoppable; but what time does to your brain is up to you.

What if brain aging depends not only on the passage of time, but also on how we live… and how we eat?

Memory loss, lack of concentration, and mental sluggishness are among the greatest fears associated with aging. We know that the brain inevitably ages, but current science shows that it does not age in the same way or at the same rate for everyone.

In this book, nutritionist Ainoa Navarrete invites us to understand what really happens in our brains as the years go by—and, more importantly, how much room we have to influence that process. Through a clear, rigorous, and approachable lens, the book bridges scientific evidence and clinical practice to explain how diet modulates key factors in cognitive decline, including inflammation, oxidative stress, and gut microbiota health.

Far from miracle promises or restrictive diets, you will find practical tools to build a sustainable eating pattern that protects your cognitive function over the long term and contributes to the prevention of neurodegenerative diseases. Because the goal is not to avoid aging, but to decide on what terms you want to age.

Ainoa Navarrete Pérez is a registered dietitian-nutritionist specializing in clinical nutrition. She graduated in Human Nutrition and Dietetics from the Autonomous University of Madrid and completed a Master's degree in Genetic, Nutritional and Environmental Factors in Growth and Development. She is currently pursuing her doctoral thesis in biomedicine at the University of Córdoba. Her professional career combines clinical practice with research, with a special interest in neurodegenerative diseases such as multiple sclerosis. She also serves as a teaching collaborator in the Master's program in Nutrition at the University of Córdoba, contributing to the training of new healthcare professionals. Her approach is based on personalized nutritional interventions and the rigorous application of scientific evidence, with the aim of promoting people's health and well-being through adapted and evidence-based nutrition.
