The Enzyme Treatment of Cancer and Its Scientific Basis

John Beard D.Sc.
Foreword by Nicholas J. Gonzalez MD
ISBN: 978-0982196526; available at Amazon

Dr. Beard’s examination of the placenta led him to conclude that in its early stages, this tissue behaves much as a cancerous tumor. He then proposed that pancreatic enzymes regulate placental development, and in turn represent the body’s main defense against cancer. Though in his lifetime the scientific community never embraced his ideas, modern research on stem cells increasingly confirms many of Dr. Beard’s theories. The reproduction with a foreword by Dr. Nicholas Gonzalez is now out of print, though you might find used copies at the above link on Amazon. Since the book was published in 1911, it is in the public domain and has been posted online. We cannot vouch for the completeness or accuracy of the posted version.

Nutrition and Physical Degeneration

Weston A. Price DDS
ISBN: 978-0916764203; available at Amazon.

In the 1920s, Dr. Weston Price and his wife traveled to 14 different countries and some of the most remote areas in the world investigating the health of the local populations. Those who followed traditional dietary practices had excellent dental structure and overall superb health. Those who adopted industrialized and processed foods such as white flour, white sugar, refined vegetable oils and canned goods, quickly developed dental problems and disease. This book includes hundreds of photos that document Dr. Price’s findings. Since few traditional cultures exist today, this carefully documented study is invaluable. Dr. Price’s terminology does not meet current standards of political correctness, but his respect and admiration for the traditional peoples of the world shine through.
