Medical Endorsements

T. Colin Campbell, PhD

Cornell University
U.S. Mastermind and Author of "The China Project"

“I have often told audiences around the U.S. that CHIP is the premier community based program in the country. I have observed the program first hand on several occasions and I could hardly be more positive. Every community in the country should know about the CHIP program and give it a try."

“This CHIP Program, to my way of thinking, can potentially affect the treatment of Western diseases in a more cost-effective and outcome-effective manner better than any other strategy I know.”

William P. Castelli, MD, NIH
Former Director – Framingham Heart Study

“I would like to take this opportunity to recommend Dr. Diehl (and the CHIP Program). Throughout his life, Dr. Diehl has been a keen worker on the health maintenance side of medicine. Through his writing, seminars, and programs, he has brought a very powerful message to all who would listen in how to use diet and exercise, reflection on the more important things in life, to prevent the number one killer in our society--atherosclerotic diseases--such as heart attacks, strokes, peripheral vascular diseases and cancers.”

“As Medical Director of the SwedishAmerican Health System's Center for Complementary Medicine and Clinical Professor of Medicine at University of Illinois College of Medicine-Rockford, I have personally witnessed the transformation CHIP participants experience in arresting, reversing, and preventing chronic Western diseases.
