Could a simple, all-natural, whole-foods diet - the same diet of our 19th century and previous ancestors - both prevent and treat age-related macular degeneration (AMD)?

Dr. Knobbe is a both an ophthalmologist and Associate Clinical Professor Emeritus, formerly of the University of Texas Southwestern Medical Center, and he has proffered a revolutionary hypothesis for the etiology (cause) of AMD, a hypothesis which holds that AMD is a disease both initiated and driven by man-made, processed, nutrient-deficient, and toxic food consumption.
