Abstract：As global aging accelerates achieving healthy longevity has become a focal point of current research. This article aims
to review the impact of nutrition and lifestyle factors on healthy longevity with a focus on key elements such as dietary patterns
physical activity sleep smoking and alcohol consumption. Dietary patterns significantly influence healthy longevity. Traditional diets
in longevity regions—such as the Mediterranean Nordic and Okinawan diets—as well as modern healthy dietary patterns like the
DASH diet are associated with lower mortality rates and increased health spans. Plant-based diets in particular help maintain lower
lipid levels and improve cardio metabolic health and cognitive function. In terms of lifestyle adequate physical activity and high -
quality sleep are crucial for extending lifespan. There is a dose-response relationship between physical activity and all-cause mortality
with approximately seven hours of sleep being the optimal duration for longevity. Additionally Smoking significantly reduces healthy
life expectancy whereas the relationship between alcohol consumption and health exhibits a "J-shaped" curve although this remains a
subject of ongoing debate. Comprehensive interventions involving nutrition and lifestyle can significantly extend healthy life expectancy
by 8~ 10 years. Current studies are mostly based on Western populations lacking cross -cultural long -term cohort evidence and
evaluation methods rely on subjective reports. Future research should integrate digital technologies for precise monitoring optimize
multi-dimensional intervention strategies and focus on the applicability for populations experiencing functional decline in order to
promote the achievement of healthy aging goals.
