The abundance of food in the developed countries of the world has seemingly spawned an epidemic of disorders connected to the food. Extremes such as intensive concern about one's body image and total disregard for it have resulted in countries which contain enormous segments of the population who are either obese or bordering on anorexia nervosa. This book gathers state-of-the-art research from leading scientists throughout the world which offers important information on understanding the underlying causes and discovering the most effective treatments for eating disorders.
