National Nutrition Month Series #1: The Principles of the Longevity Diet
The Longevity Diet is more than a meal plan. It is a science-backed lifestyle rooted in over 25 years of research led by Dr. Valter Longo, Director of the Longevity Institute at USC and founder and scientific advisor of L-Nutra.
Inspired by the dietary patterns of the world’s longevity sites, regions with the highest population of healthy centenarians, this approach focuses on improving healthspan - not just adding years to life, but adding life to those years.
At its core, the Longevity Diet emphasizes:
• A daily intake of 55-65% carbohydrates, 30-35% healthy fats, and 10-11% protein.
• Abundant plant-based foods rich in fiber and phytonutrients.
• A mostly vegan pattern with fish consumed sparingly 2 to 3 times per week.
• Limited processed foods, added sugars, and unhealthy fats.
• Strategic fasting cycles to support cellular rejuvenation.
When paired with periodic fasting, these principles work together to support metabolic health, cellular health, and healthy aging.
