Dr. John Scharffenberg, a 101-year-old nutritionist and adjunct professor at Loma Linda University, continues to lead an active and independent life. Despite his family’s history of heart disease and Alzheimer’s, he attributes his longevity to specific lifestyle choices rather than genetics. He emphasizes that adhering to seven key habits can help prevent age-related diseases and promote a longer, healthier life.
1. Avoid Smoking
Dr. Scharffenberg has never smoked and strongly advises against it. He references the 1964 Surgeon General’s report, which highlighted the extensive health risks associated with tobacco use. Smoking remains a leading cause of preventable diseases and deaths worldwide, affecting nearly every organ in the body.
2. Reevaluate Alcohol Consumption
While some studies suggest moderate alcohol consumption may have health benefits, Dr. Scharffenberg points out that these are outweighed by the increased risk of cancer. He aligns with the World Health Organization’s stance that abstaining from alcohol is the safest choice for health.
3. Prioritize Regular Physical Activity
Emphasizing the importance of exercise, especially between the ages of 40 and 70, Dr. Scharffenberg believes physical activity is even more crucial than nutrition. He recommends activities like brisk walking and gardening, noting that regular movement can significantly reduce mortality rates.
4. Maintain Structured Eating Habits
To manage weight and overall health, Dr. Scharffenberg advises eating at set times and avoiding snacking. He believes that disciplined eating schedules help prevent overeating and contribute to better metabolic health.
5. Embrace a Plant-Based Diet
Advocating for a vegetarian lifestyle, Dr. Scharffenberg emphasizes the benefits of consuming a diet rich in plant-based foods. He suggests that such a diet can help prevent chronic diseases and promote overall well-being.
6. Foster Positive Relationships
Dr. Scharffenberg highlights the importance of social connections for mental and emotional health. Engaging in meaningful relationships and community activities can provide support, reduce stress, and enhance quality of life.
7. Cultivate a Positive Outlook
Maintaining an optimistic mindset is another cornerstone of Dr. Scharffenberg’s philosophy. He believes that a positive attitude can influence physical health and longevity, encouraging individuals to focus on the good and stay resilient in the face of challenges.
Dr. Scharffenberg’s life serves as a testament to the impact of intentional lifestyle choices. By adopting these seven habits, individuals can take proactive steps toward a longer, healthier life, demonstrating that longevity is influenced by more than just genetics.
