Sylvia Zook
"A powerful motivator," especially associated with a lifetime of dealing with an undiagnosed, slow growing brain tumor. Yet able to work 60 hour weeks due to the lifestyle of Eatin' After Eden, Dr. Zook’s dynamic mission has inspired many with clinical practice, seminars, wellness conferences, lectures, newspaper columns, editor-in-chief and publisher of two  newsletters, with an e-zine newsletter, book, and website—all reaching out with her unconventional but sound scientific articles of how to and why.
With the encouragement and guidance of a leading nationally recognized specialist there, W. M Ringsdorf, DMD, at the University of Alabama Medical Center, Birmingham, AL, the student came to understand           doctors would have no time to do the research for her complicated, unresolved condition. She must begin this for which she ultimately included research for many others “falling through the cracks.” These long years of research  led her to the master gland, and to the OHSU University of Oregon medical school where a large adenoma was confirmed by a dynamic MRI in that department specializing in this condition.
Dr. Zook studied applied enzymes under Dr. Howard F. Loomis, Jr., a student of the noted authority and pioneer in enzyme research, Edward Howell (1898-1995). It was Dr. Howell who first recognized and delineated the supreme importance of food enzymes for human nutrition.
This practical approach to teaching, considers individual clients' nutritional needs rather than simply symptoms. She holds that health care practitioners imparting knowledge empower and motivate clients to profitably assume responsibility for their level of wellness, whether in restoration or maintenance of optimum wellness. After all, the Latin root of "doctor" (doctore') means "to teach." And for decades this researcher has been at the forefront of nutrition science, teaching support of the divinely designed human body’s continual effort, chiefly in avoiding and removing toxins, and in providing that which is vital for healing and maintaining optimum health, a lifestyle provided and designed by the Creator, and supported by sound science.

“Doing the most for the most,”Eatin’ After Eden is reaching round the world. Now in very active, advanced age, this resilient, persevering dynamo is being faithful to that calling, already in 8-10 countries rather than individual counseling only.

Ten years of higher education and almost 50 years of research and clinical practice have resulted in this educator's evidence-based, bioavailable personal "trial by fire" nutrition that has meant no colds or flu or other contagious conditions for more than 40 years for both she and her husband who died in an automobile accident in excellent health at age 90.

The productive lifestyle she writes about in Eatin' After Eden has enabled her to maintain the 60-hour workweeks for many decades and into advanced age. More than one physician has opined that the energizing, healing, detoxing plan for eating keeps her functioning remarkably above that of many half her age while she continues to work overtime with students, colleagues, and physicians, encouraging them to in turn teach others, after their own restoration. An amazing example is included in the introduction of her book, Eatin' After Eden.

One of the things many appreciate most about her mission is the integrity behind all that Dr. Zook gives. Her only reward is the beautiful fruit of extended, productive lives, personal and for countless others. (See Testimonies.)

As a result of her balanced teaching, “sidelined soldiers” are remarkably returned to work while others remain well and able bodied to do the work to which they are themselves called into old age. (See the example in Testimonies of a 95 year old with life extension of 15 years.)

Stay-at-home moms who are nourishing their families, and teaching them these nutritional principles, are able to convert conventional recipes for wholesome foods. Thus some congenital health issues may be avoided and genomes positively altered in these individuals and succeeding families.

"[T]he most" Dr. Zook reaches includes teachable medics who learn in studying this book and from her personal example, and benefit from this proven lifestyle. One dermatologist suffering from diabetes II and bi-pass surgery, remarked after reading it, "I knew there was something they weren't teaching us!"
