South Koreans' longevity linked to diet and active lifestyle

South Korea is emerging as a model for longevity, with its citizens experiencing a significant increase in life expectancy. Between 2000 and 2021, life expectancy in South Korea grew by nearly eight years, according to the World Health Organization. This contrasts sharply with the United States, where life expectancy has stagnated, falling to the lower end among developed nations.

A cornerstone of this longevity appears to be diet. A journalist visiting a South Korean school noted the prevalence of vegetables like lettuce, radish salad, and kimchi, alongside seasonal fruits, in student lunches. School nutritionists emphasize that these meals are designed to be both nutritious and educational. This focus on vegetable and fruit consumption is a stark contrast to the U.S., where studies indicate a significant portion of children and adults do not consume enough produce daily.

If you want to live a long and healthy life, you'd better be in South Korea than in the United States.

Beyond diet, an active lifestyle plays a crucial role. Dr. Geon-Ha Kim, a neuroscientist, identifies physical activity, social engagement, and mentally stimulating activities as vital for "super-aging" individuals, those who maintain sharp cognitive function well into old age. Social media influencer Park Mak-Rye, known as "Korean Grandma," exemplifies this, sharing healthy recipes, skincare routines, and exercise tips at 79. Her active lifestyle and close friendships are cited as key to her well-being.

Regular physical activity that elevates heart rate is strongly linked to a reduced risk of premature death, potentially by as much as 40 percent. The combination of a nutrient-dense diet, consistent exercise, strong social bonds, and continuous mental engagement offers a comprehensive blueprint for a longer, healthier life, lessons that are increasingly relevant globally.

Among the most important lifestyle factors are physical activity, social contacts, and new, challenging activities.
