Who is Prof. Arnold Ehret?
Professor Arnold Ehret, revered as the father of naturopathy, is the most important pioneering researcher and author regarding the health and preservation of the human body. No other scientist, doctor, dietitian, or author has surpassed Ehret’s work concerning the cause and cure of chronic disease and human illness. Through years of research he rediscovered that the human body is an “air-gas engine” that is powered exclusively by oxygen, and that a diet consisting of starchless fruits and green-leafy vegetables (mucusless foods) is the only food fit to be eaten by humans. Among other important writings, Ehret produced a brilliant dietetic treatise entitled the Mucusless Diet Healing System/Rational Fasting which offers a methodical approach to eating that can be used regardless of age, gender, race, or sickness to achieve superior health.
