Categories: Health & Wellness
Publisher: Medinform Publishing

Companion volume to the bestselling Gut & Psychology Syndrome—the book that launched the GAPS diet—which has been translated into 22 languages and sold more than 300,000 copies.

Since the publication of the first GAPS book, Gut and Psychology Syndrome, in 2004, the GAPS concept has become a global phenomenon. People all over the world have been using the GAPS Nutritional Protocol for healing from physical and mental illnesses.

The first GAPS book focused on learning disabilities and mental illness. This new book, Gut and Physiology Syndrome, focuses on the rest of the human body and completes the GAPS concept. Allergies, autoimmune illness, digestive problems, neurological and endocrine problems, asthma, eczema, chronic fatigue syndrome and fibromyalgia, psoriasis and chronic cystitis, arthritis and many other chronic degenerative illnesses are covered. Dr. Campbell-McBride believes that the link between physical and mental health, the food and drink that we take, and the condition of our digestive system is absolute. The clinical experience of many holistic doctors supports this position.

Reviews and Praise

  • “Dr Natasha Campbell-McBride has written a very important book! Not only has she demonstrated the vital role of microbiome in all chronic disease, but she has given us a practical healing protocol on how to deal with the problem. Her views on autoimmune disease are deep and based in clinical experience.

    This book should be read by every person with a chronic degenerative disease and by every medical professional who works with these patients. I warmly recommend it!”–Professor Yehuda Shoenfeld MD, Zabludowicz  Center for Autoimmune Diseases, Chaim Sheba Medical Center, Israel

  • “Dr. Natasha has done it again! Gut and Physiology Syndrome takes an in-depth look at the underlying causes of today's health crisis--environmental and dietary poisons--and then provides a comprehensive plan for detoxification and nourishment to achieve the good health and clear mind that is the birth right of every adult and every child. Especially appreciated are suggestions for reviving our natural instincts for knowing what to eat for our own particular metabolism. Gut and Physiology Syndrome is an important contribution to our collective search for good health.”–Sally Fallon Morell, President of The Weston A. Price Foundation

  • “I recently had the opportunity to review Natasha Campbell-McBride's new book Gut and Physiology Syndrome.  Natasha has been a valued colleague and friend of mine for many years.  In fact, there are few other medical people who have had such a positive influence on my thinking and my practice of medicine as Natasha. Natasha is a creative thinker and a deep seeker for the truth wherever it may lie.  Natasha revolutionized the world of medicine with her original GAPS concepts and books.  She showed us in clear and practical terms that microbes are not our enemies and that learning to work with our internal microbiome is one of the keys to not only our own health, but the health and survival of our planet.

    The beauty of Natasha's work is that, unlike most, she takes this new understanding of our crucial relationship with the microbial world and put it into a doable, effective, action plan. Natasha's GAPS Diet has been a cornerstone of my medical work for the greater part of a decade. 

    With her new book, Natasha expands on her vision of the role of our microbiome in our entire physiology.  She continues to break new ground as she gently pushes us into a new more honest, realistic and ecological understanding of life. This work is a tremendous contribution towards remediating our current medical situation: one, in which our current medicine is largely another source of sickness and disease, to one, where we can begin to heal the tremendous suffering we are experiencing all around us. Please buy this book, think about what is being said and, if possible, put these ideas into action. Our world depends on it!”–Dr Thomas Cowan MD, author of Cancer & the New Biology of Water

  • “This book is a gem!  A wealth of information about the central role of the gut microbiome in maintaining the health of all the organs of our body. A central theme is that infectious disease only happens when our tissues are unhealthy, due to nutritional deficiencies and toxic chemical exposures, and infection is part of a repair mechanism to restore health. For example, fungi release nanoparticles that can absorb toxic metals and facilitate their removal from the body. This book will change your perspective on health and disease and teach you how to heal your body naturally.”–Dr Stephanie Seneff, PhD

  • “This book is a tour de force! A revelation! With chronic illness affecting over half the US population, with a new generation of children sicker and dying younger than their parents' generation—if this continues, we are facing the deterioration of our civilization and humanity. Dr Campbell-McBride reveals the damage is mostly self-inflicted!

    Dr Campbell-McBride does more than show us the causes of illnesses, she gives us practical ways of reversing (and preventing) the deterioration of health and offering us hope for true healing. This book should be required reading in every medical school.

    Established ways are slow to adapt and change. Therefore, it is up to the individual healthcare practitioner, the parent with a chronically ill child, or adult (seeking to reverse conditions they were told were incurable), the health-conscious consumer (wishing to optimize and preserve their well-being and that of their family) to read this book. Lives are at stake.”–Tedd Koren, DC, author of Cancer is Natural, So Is the Cure

  • “Well, Dr Natasha has done it again! This book abounds rational information and wisdom. Her explanation of the body's physiology is brilliant, yet easy to comprehend.

    Gut and Psychology Syndrome was a revelation to the world of autism and mental illness. Gut and Physiology Syndrome restores hope to all people suffering from chronic diseases and unexplained symptoms. I can't thank her enough!”–Beatrice Levinson, Traditional Naturopath, Certified GAPS Practitioner
