The Maverick M.D.

Dr. Nicholas Gonzalez and His Fight for a New Cancer Treatment

The Authorized Biography
By Mary Swander
When Nick Gonzalez was a medical student, he stood beside his father's deathbed and vowed that he would find a cure for cancer. Nick imagined his future as a researcher toiling away in a lab in Memorial Sloan Kettering, working on conventional approaches to the disease. Yet Gonzalez's life was anything but conventional. At the urging of Linus Pauling, he had already left an accomplished journalism career and entered Cornell Medical School.
Gonzalez's path took another turn when he met the controversial Dr. William Kelley, a dentist who, through an alternative nutritional approach, had arrested his own pancreatic cancer. Kelley had become infamous when he'd tried to help others.
The Maverick M.D. is the story of how Dr. Nick Gonzalez perfected the scientific theory behind Kelley's work and put the protocol into practice in New York City. Gonzalez drew courage from his Christian faith, from his Mexican-Italian-American family, and from key loved ones, colleagues and mentors. He spent years treating patients with the most serious conditions--from cancer to diabetes to lupus. But he wasn't satisfied as an outlier in the medical community. He wanted his work put to the test with a clinical trial.
This book portrays a man who fought for the acceptance of a nutritional cancer treatment in the halls of some of the most established U.S. medical institutions. Against intense opposition, Nick Gonzalez's determination held up until the end--a scientist who developed a therapy that saves lives and promotes the healing of the human mind, body and spirit.

Nutrition and The Autonomic Nervous System:

The Scientific Foundations of The Gonzalez Protocol


By Nicholas J. Gonzalez, MD


In this global award-winning book, Dr. Nicholas Gonzalez (developer of The Gonzalez Protocol® for the treatment of cancer and many other degenerative diseases) explains the importance of nutrition in maintaining and restoring the autonomic nervous system balance that is so crucial to good health. WINNER OF THE 2018 BOOK EXCELLENCE AWARD IN THE CATEGORY OF DIET & NUTRITION. 


Dr. Gonzalez describes how individual variation in nervous system function means that different individuals require different types of diets (ranging from largely raw food and vegetarian to diets high in fatty red meat, and every variation in between) in order to achieve good health.


Drawing upon more than twenty-five years of private practice in New York, and prior research by Drs. Pottenger, Gellhorn, and Kelley, he also explains why nutritional supplementation protocols similarly need to be individualized for optimal autonomic nervous system function.


While this book is not a how-to manual, reading it will help you better understand how to maintain or improve your own health or, if you are a health professional, to better assist your patients to remain healthy or recover from illness-without potentially harmful medications.

The Enzyme Treatment of Cancer and Its Scientific Basis

John Beard, D.Sc.; with a foreword by Nicholas J. Gonzalez, M.D.

Currently out of print.


Enzyme Treatment cover Dr. John Beard's study of the mammalian placenta led him to the conclusion that in its early incarnation, 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. In 1911, he published The Enzyme Treatment of Cancer to favorable reviews. Though in his lifetime the scientific community never embraced his ideas about cancer—he died in relative obscurity in 1924—in recent years, evidence from molecular biology and stem cell research increasingly confirms many of Dr. Beard’s fundamental precepts. This historic work is now available again, in a carefully recreated reproduction with a foreword by Dr. Gonzalez. Click here for more information …

“What Should I Eat?” Lecture Recording

 The world of diet and nutrition can be confusing, not only to lay people seeking a healthier way of life, but also to professionals trying to sort through a morass of sometimes contradictory information. Many nutritional experts propose a single “ideal” diet for everyone, though each of these experts may recommend a diet at odds with the others. Some believe all humans should follow a high meat, high animal fat diet; others, one emphasizing plant foods; still others, a more balanced “Mediterranean” type diet. Not only can these conflicting opinions lead to confusion among those trying to improve their health, many end up on a diet that just isn’t right for them. In this lecture, Dr. Gonzalez discussed the physiology and biochemistry of dietary individuality,  and made sense out of the confusion in the nutritional field and the contradictory statements of “experts.” He reviewed the work of such pioneers as Dr. Weston Price, who showed that traditional groups of humans thrived on many different types of diets; Dr. Francis Pottenger, who demonstrated the effect of nutrients on the nervous system; and Dr. William Donald Kelley, who synthesized the work of these researchers into a coherent plan of individualized dietary and supplement prescriptions. Please note: this product will not give specifics for the ideal diet for any individual, and is not meant to be used as a self-help guide. Length: 161 minutes.

“Different Diets for Different Types” Lecture Recording

Available on Amazon

Please note: this product will not give specifics for the ideal diet for any individual, and is not meant to be used as a self-help guide. Length: 4 hours.

“A Nutritional Approach to Cancer” Lecture Recording

Dr. Gonzalez also presented a number of case reports demonstrating the value of the therapy against both cancer and non-cancer illnesses.

Versions on audio CDs or DVDs are available through Fleetwood Onsite Conference Recording. Length: 5.5 hours.

“The Enzyme Therapy of Cancer” Seminar Recording

On April 18, 2009, Nicholas J. Gonzalez, MD spoke at a seminar sponsored by Nutri-Link LTD and held at the Royal Society of Medicine in London, England. Over several sessions totalling nearly seven hours, he discussed the scientific support for his approach to cancer and other degenerative diseases. He reviewed the history of the enzyme treatment of cancer, dating back to Dr. John Beard, the British embryologist who 100 years ago first suggested that the pancreatic enzyme trypsin represents the body’s main defense against cancer. A reference list and an excerpt (3.8 MB) are available.

Please note: because of problems in the recording process during the seminar, Session 1 has occasional defects in the sound as demonstrated in the excerpt. Session 1 also has some background noise (1.3 MB) due to microphone problems that were corrected after the first 15 minutes, and there are variations in volume at times in most of the lectures. However, the lectures are comprehensible throughout.

The lectures are only available as a download of five MP3 files representing five sessions. You may purchase the complete set, or you may purchase Session 1 and then return to purchase Sessions 2-5. Length: 6.5 hours.
