News | Global Longevity Summit issues four principles for extending healthy life through science and culture
The first Global Longevity Summit was recently held in Kyotango, Japan. Scientists, clinicians, policymakers and community leaders from around the world proposed that integrating biology, lifestyle change and cultural practices can extend lifespan while maintaining health, independence and purpose in later life. The conference report was published in npj Aging.
The summit identified four pillars of healthy longevity: maintaining social connections, practicing gratitude, exercising regularly and following a diet based on plant protein and dietary fiber. The framework draws on Kyotango, where the high concentration of centenarians makes the region a real-world longevity laboratory.
Rapid population aging makes healthy lifespan a central issue
Longer lives and falling birth rates are rapidly changing population structures. Although people live longer, many experience chronic disease and declining function late in life. Ensuring that added years are healthy was the summit's central theme.
Japan is a prominent example: nearly one-third of its population is aged 65 or older. Kyotango's exceptional longevity provides a unique view of the biological factors, social structures and cultural habits associated with long life.
Molecular longevity science: epigenetic clocks, autophagy and the gut microbiome
Research teams presented leading findings at the molecular level.
Epigenetic aging: organs age at different rates, with limited but measurable lifestyle effects
Aging-biology pioneer Steve Horvath presented DNA-methylation-based "epigenetic clocks" used to estimate the biological age of organs. He noted:
Families of centenarians often show slower epigenetic aging
The cerebellum and retina age most slowly, while blood and bone age faster
Lifestyle affects biological age, but the effect is modest
Interventions such as Omega-3 produce measurable but small improvements
Obesity substantially accelerates liver aging
The "Hispanic health paradox" and low biological age among the Tsimane people of South America offer new population clues for aging research
Autophagy as a central cellular-maintenance mechanism: inhibiting Rubicon may extend lifespan
Tamotsu Yoshimori emphasized that autophagy is central to cellular homeostasis and recycling damaged components. Rubicon, a protein that increases with age, inhibits autophagy. Animal studies show that suppressing Rubicon may extend lifespan and improve neurological function.
Early areas of investigation include fermented-tea extracts and lifestyle interventions intended to promote autophagy, but all require rigorous validation. Rubicon's role in spreading aging signals through exosomes is also considered a potential breakthrough area.
Yoshimori has established a research company and the Japan Autophagy Consortium to help bring this research to the public.
Gut microbiota: centenarians have a microbiome that is not younger, but distinctive
Francis Chan focused on the gut microbiome, noting:
With age, microbial diversity falls, barrier function weakens and inflammation rises
Centenarians do not have a "young microbiome," but a structure with rarer, less common beneficial bacteria
Microbial imbalance early in life affects long-term health
A prebiotic-plus-probiotic (synbiotic) trial for long COVID showed potential to improve fatigue and cognitive symptoms
Microbiome aging can be monitored through diversity, population structure, metabolites and functional performance
From community to policy: building a sustainable "longevity society"
Another central theme was how social systems can help older adults remain connected, capable and purposeful.
The "Platinum Society" vision: turning aging from a burden into social capital
Tomoo Matsuda advocated a "Platinum Society" in which older adults are value creators rather than passive recipients of care. Successful community models included:
The "Exadon" program, combining exercise with taiko drumming rhythms
Multipurpose community centers promoting intergenerational interaction
Adapted living spaces that reduce fall risk and increase independence
The summit noted that evidence for many programs remains observational and more standardized evaluation frameworks are needed.
Rural aging: digital tools alongside traditional culture
Cases from rural Italy and Japan showed that population loss, knowledge gaps and limited services are common regional problems. Stefania Bandini said digital tools can identify vulnerabilities such as unsafe walking routes, excessive distance to healthcare facilities and inadequate care networks.
She emphasized that technology must be integrated with local culture and social structures to improve older people's well-being.
Four longevity principles: the summit's joint declaration
The final declaration identified four principles for healthy longevity:
Maintain strong social connections
Follow a diet centered on plant protein and dietary fiber
Build regular activity into daily life
Use gratitude and a sense of purpose (Ikigai) as a spiritual foundation
The declaration stated that healthy longevity depends on scientific evidence, cultural sensitivity and cross-disciplinary collaboration.
Global collaboration toward an extendable healthy lifespan
The summit stressed that extending healthy life is not the task of one field, but a coordinated effort spanning biological mechanisms, clinical translation, early intervention, community design and public policy.
The combination of global cooperation and cultural wisdom will shape whether people can truly live longer, healthier and more meaningful lives.
