EXPLORE THE SCIENCE OF NUTRITION AND LONGEVITY WITH JAAN
At the Japanese Anti-Aging Nutrition Association (JAAN), we delve into the profound impact of nutrition on longevity, health, and microbiomes. Our mission is to foster collaboration and knowledge exchange among professionals, scientists, and experts from diverse fields to advance the understanding of how nutrition can promote a longer, healthier life.
WHY DO JAPANESE HAVE LONGER LIFESPAN
Discover the Power of Nutrition and Microbiota with JAAN.
Japan has one of the highest life expectancies in the world — and one key reason is its diet rich in fermented foods. These foods naturally produce bioactive compounds during fermentation that nourish and balance the gut microbiota, often called our "second brain". A healthy gut communicates with all organs in the body, supporting immune strength, energy levels, mental clarity, and graceful aging.
NUTRITION & THE GUT - THE KEY TO VITALITY
Emerging research highlights the central role of the gut microbiome in regulating immune function, metabolic processes, and even cognitive health. The gastrointestinal tract is not only responsible for nutrient absorption but also serves as a critical interface between diet and systemic health. Diets rich in fiber, polyphenols, and fermented foods have been shown to enhance microbial diversity, promote the production of short-chain fatty acids, and reduce inflammation—factors essential for maintaining homeostasis and vitality. Optimizing gut health through targeted nutrition is thus a foundational strategy for preventing chronic disease and promoting overall physiological resilience.
JAAN promotes research on the link between nutrition and gut health.
