Dr. John Scharffenberg, a physician, nutritionist, and professor, built a long and influential career on the principles of preventative medicine and lifestyle-based health. Born in China in 1923 and later trained at Loma Linda and Harvard, he emerged as a leading voice in public health, advocating for simple yet powerful changes to extend both lifespan and healthspan. His personal example as a centenarian and his prolific work, including teaching and international lectures, underscored his core message: health is primarily determined by daily choices, not just genetics.
The Cornerstone of His Philosophy: Lifestyle Over Medicine
Throughout his decades-long career at Loma Linda University, Dr. Scharffenberg consistently argued that simple lifestyle habits could mitigate the risk of chronic diseases far more effectively than medication alone. He was a staunch proponent of the power of prevention, highlighting how daily activity and dietary choices directly influence health outcomes.
His advocacy emphasized several key pillars:
- Daily Movement: Scharffenberg believed that consistent, daily exercise was paramount to longevity, stating it was even more important than nutrition. He practiced what he preached, remaining active well into his second century with activities like gardening.
- Plant-Based Diet: Following his Seventh-Day Adventist faith, he became a lifelong vegetarian at age 20 and was a passionate advocate for plant-based nutrition. He championed the idea that a plant-based diet could reduce the risk of age-related illnesses, pointing to scientific recommendations and his own decades of research.
- Abstinence from Harmful Substances: He completely abstained from both tobacco and alcohol, framing them as lethal risk factors for cardiovascular disease and cancer. He often cited authoritative sources like the Surgeon General's report on tobacco and more recent studies on alcohol's risks.
