Raymond Francis, M.Sc. was too weak to leave his bed. Or even lift his head from the pillow. His diagnosis: acute chemical hepatitis, chronic fatigue, multiple chemical sensitivities, and autoimmune syndrome. How did his prognosis shift from certain death to healthy recovery?

Francis explains his groundbreaking theory in this way: One disease, two causes of disease, and six pathways between health and disease. A graduate of MIT, Francis is a trained chemist and health educator recognized around the world as a leader in the emerging field of optimal health maintenance. He’s also the president of Beyond Health Corporation and the publisher of Beyond Health News. His book, Never Be Sick Again: Health is a Choice, Learn How to Choose It is the focus of today’s Conversations Live with Vicki St. Clair.
