Prof. Arnold Ehret was a German healer, dietitian, philosopher, teacher, visionary, and one of the first people to advocate fasting and a plant-based, mucus-free lifestyle as a healing therapy. For over 100 years, his written works and teachings have touched the lives of numerous health-seekers. Ehret's groundbreaking work shows that pus- and mucus-forming foods are not only unnatural for humans to eat, but the fundamental cause of human illness. He offers the most successful "system" for removing illness-causing residues from the body through fasting and a mucus-free diet. Today, Ehret's works are increasing in popularity as people learn of the healing power of plant-based diets and fasting. The world needs Ehret's work now more than ever. In an era where people consume genetically modified, mucus-forming frankenfoods daily, the simplicity and truthfulness of Ehret's teachings can transform humanity for the better!
