Regain Your Health is an advance in food allergy studies on several levels. Not only does it contain brand new, previously unpublished information on how food reactions interfere with the blood flow, it has a detailed discussion of the benefits of fasting. The first part of the book describes the food and chemical allergy condition and reveals what the author has learned about blood flow involvement (which explains the wide variety of symptoms generally laid at the door of allergies). The second part is a program of recovery. Rather than just advising avoidance, it suggests a way to effectively alter the internal environment so that one is no longer susceptible to the foods one eats.
