Dr. Kellogg was one of the first to recognize the importance the colon plays in maintaining our health. Irregularity is a guarantee that our system is heading for trouble. This book explores ways to keep regular and though written in 1916, it still has many excellent suggestions. If we would follow all the correct ways of diet and exercise, then the colon would have no problem performing the functions for which it was intended. John Harvey Kellogg was years ahead of his profession in many fields of medicine. This book will prove most interesting to see how he solved the problems at a time when most of the medical profession felt the colon to be a useless left-over appendage from prehistorc ancestors.
