Dr. John H. Kellogg believed that a diet of fresh vegetables, fruits, grains, yogurt, nuts, cereals and fresh milk coupled with lots of physical exercise, sunshine and fresh air were the cornerstones for a healthy body. His gym introduced treadmills and standing bikes. He was also certain that tobacco caused cancer, penning his first book on the subject: “Tobaccoism or How Tobacco Kills.� Hardly news today, but he conceived these ideas 125 years ago while building his Battle Creek Sanitarium, known as the San, into the world's largest and most advanced hospital and health spa. Although his younger brother, Will K. Kellogg, built the Kellogg cereal empire, J.H. was equally successful as a prolific author—50 books, many of them leading medical texts--health and fitness guru, inventor, surgeon and philanthropist. The novel and 1994 movie "The Road to Wellville," starring Matthew Broderick, John Cusack and Sir Anthony Hopkins, were based on his story and ostensibly tell about the darker, more lurid and questionable sides of his health practices, albeit with a large dollop of fiction and patently ill-conceived humor.
