Renata Taylor-Byrne and Jim Byrne have outlined key research findings on the relationship between diet and exercise, on the one hand, and the intensity of anger, anxiety and depression emotions on the other. The book contains a list of foods that must be excluded to ensure optimal brain functioning and mood control. There is also a detailed consideration of a range of modern diets, with guidelines for developing a personalised diet; and the skills needed to change difficult dietary and exercise habits. There are six parts to this book: The first part deals with diet and nutrition and how they influence anxiety, anger and depression. The second part of the book deals with physical exercise and how it can affect these common emotional problems. The third part is a description of a 'stress and anxiety reduction' diet and offers guidelines for understanding different types of diets and their effects. The fourth part shows some of the key findings from the science of nutritional deficiency, and the role of inflammation in the creation of depression. The fifth part is a summing up of the key findings of the book, so that you can spot the most useful material that you can use for yourself - or for your clients, if you are a health-care or psychotherapeutic practitioner, counsellor or psychologist. And the sixth part is our attempt to coach you through the process of habit change; and to give you a map to guide you through the process of accessing, learning and applying the transformative information in this book.
