"By emphasizing the whole-food, plant-based diet as mankind's natural food, the authors of this book have deepened our understanding and our belief. I am convinced that this book will bring closer the day when cancer specialists the world over will wake up and realize that a new, effective treatment against cancer now exists and is ready for use.”--John Kelly, MD, Dublin, Ireland, Author, Stop Feeding Your Cancer

“As a health and medical specialist, to me the 4Leaf Survey is a highly instructive and practical motivational tool, one I offer daily to most of my patients, from babies just starting solids--to the elderly. In my practice, I wouldn't be without it. The “4Leaf Guide to Vibrant Health” is therefore a must read.”--John Green, MD, family physician, Melbourne, Australia

“In addition to summarizing the primary health and environmental benefits of adopting a whole-food, plant-based diet, Dr. Graff and J. Morris Hicks include motivational case histories, access to valuable support resources and easy-to-understand tips and strategies.

“Even though it is not in my economic self-interest, I highly recommend the plan put forth in this amazing book to anyone who is interested in optimizing their own health, the health of our Earth, and the health of all the non-human species who share this beautiful blue and green planet with us. As an Interventional Radiologist who repairs damaged arteries with angioplasty and stents, I personally profit from the havoc that the modern industrial diet plays on our arteries and organs. If everyone were to eat this way, I would be out of a job! Fortunately, I have a lot of hobbies.” Ted D. Barnett, MD, Interventional Radiologist, Rochester, NY

“The thesis of this book is simple—and it provides solid, fact-based reasons for its conclusion: It is imperative for humans to get off the meat, egg and dairy drug. For me, these reasons also alluded to the petals of the four-leaf clover: faith, hope, love and luck. Lucky people will find this book--ethical and wise people will take its message seriously.”--Philip Wollen, Humanitarian Philanthropist, Former General Manager of Citicorp in Australia.
