Meet the Doctor Who Turned 101 and Still Inspires the World to Live Better
— A Century of Wisdom from Dr. John Scharffenberg
A Life Rooted in Simplicity and Discipline
Dr. John Scharffenberg, born in 1923 in China, is a Harvard-trained physician and public health expert who has dedicated his life to understanding what truly contributes to long, meaningful living. Unlike many who chase health fads, he followed a simple, consistent lifestyle grounded in science, spirituality, and purpose. Now at 101, his way of living is a model of sustainable well-being.
No to Alcohol, Yes to Science
For decades, moderate alcohol consumption was thought to be heart-healthy. Dr. Scharffenberg disagreed—even before research confirmed that any level of alcohol increases the risk of cancer, liver damage, and cognitive decline. His complete avoidance of alcohol wasn’t fear-based—it was a calculated, educated choice, now supported by global health authorities.
Movement with Purpose
Dr. Scharffenberg didn’t depend on gym memberships or rigid fitness programs. Instead, he worked on a forested property—clearing land, planting trees, and maintaining a vast garden with thousands of strawberry plants. This consistent, natural activity aligns with studies showing that walking just two miles daily can nearly halve one’s risk of early death. His physical routine was practical, engaging, and life-affirming.
Intermittent Fasting, Done Simply
One of his long-standing practices was skipping dinner. This form of intermittent fasting gave his body extended periods of rest from digestion, promoting better metabolic health, blood sugar balance, and weight management. Unlike trendy fasting plans, his approach was consistent and gentle—integrated into his daily rhythm for decades.
The Plant-Based Power of the Adventist Diet
As a Seventh-day Adventist, Dr. Scharffenberg follows a predominantly plant-based diet—a lifestyle proven to promote longevity. His meals include wholesome, unprocessed foods such as mangoes, potatoes, legumes, and nuts. Not only is this diet nutritious, but it’s also flavorful and sustainable, avoiding extremes or deprivation.
Loma Linda, California—where he taught for many years—is one of the world’s five “Blue Zones,” regions known for their high concentrations of centenarians. His diet mirrors that of this long-living community.
Smart Sugar and Fat Choices
Dr. Scharffenberg avoids added sugars and saturated fats. Instead, he opts for natural sweetness from fruits and healthy fats from nuts and seeds. He uses creative alternatives like cashew cream in place of sugary desserts. His approach aligns with the American Heart Association’s recommendations and supports heart health without sacrificing taste.
Mental, Emotional, and Spiritual Health
Living well isn't just about diet and movement—it’s also about meaning. Dr. Scharffenberg continued teaching and mentoring well into his later years, maintaining mental sharpness and a sense of purpose. His faith, community ties, and service-driven life gave him emotional strength and spiritual peace—core elements of healthy aging.
