A doctor discusses the use of proper food instead of drugs to prevent and cure disease. -- Jacket. As a practicing physician for over fifty years, I have reached three basic conclusions as to the cause and cure of disease. This book is about those conclusions. The first is that the primary cause of disease is not germs. Rather, I believe that disease is caused by a toxemia which results in cellular impairment and breakdown, thus paving the way for the multiplication and onslaught of germs. My second conclusion is that in almost all cases the use of drugs in treating patients is harmful. Drugs often cause serious side effects, and sometimes even create new diseases. The dubious benefits they afford the patient are at best temporary. My third conclusion is that disease can be cured through the proper use of correct foods. This statement may sound deceptively simple, but I have arrived at it only after intensive study of a highly complex subject: colloid and endocrine chemistry. -- To the reader.
