Big Lessons the US Can Learn from a Country with One of the Fastest-Growing Lifespans

Big lessons the US can learn – In the quest for extended life, South Korea has emerged as a global standout. While the United States struggles with stagnant or declining life expectancy metrics, the Korean nation has seen a significant rise in average lifespan over the past two decades. This stark contrast offers a compelling case study for American health enthusiasts and policymakers. The CNN Original Series “Kara Swisher Wants to Live Forever” dives into the world of longevity, spotlighting strategies and habits that contribute to a healthier, longer life. The fifth episode, now available, explores how a culture that prioritizes wellness can inspire change in another.

School Lunches as a Health Foundation

South Korea’s approach to nutrition begins early. During a visit to a local school, journalist Kara Swisher observed students consuming meals that included lettuce wraps, radish-chive salad, and seasonal fruit. These choices, though unfamiliar to many American parents, reflect a deliberate effort to cultivate healthy eating habits. The government’s provision of free school lunches, designed by nutritionists like Yeonju Kim, ensures that children receive balanced meals while learning about food. “The lunch program isn’t just about feeding kids—it’s about teaching them what to eat,” Kim explained, emphasizing the dual purpose of these meals in fostering lifelong health.

Studies show that 80% of South Korean households prepare meals for their children, often with an eye on both taste and nutrition. This structure allows for consistent, healthy eating patterns. In contrast, American parents face greater challenges in ensuring their children meet daily fruit and vegetable requirements. A 2023 report by the US Centers for Disease Control and Prevention revealed that almost half of children aged 1 to 5 skip vegetables each day, and a third avoid fruits altogether. These habits often persist into adulthood, with nearly half of all American adults classified as having a subpar diet, according to a 2025 study.

Building Health Through Activity and Connection

South Korea’s focus on preventive care extends beyond food. Dr. Geon-Ha Kim, a neuroscientist at Ewha Womans University Medical Center, highlighted the role of physical activity, social engagement, and intellectual stimulation in maintaining cognitive vitality. These factors are particularly evident in the lives of “SuperAgers”—older adults who retain mental sharpness typically seen in younger individuals. “Regular movement and interaction are keys to preserving brain health,” Kim noted, underscoring the holistic approach to wellness.

One South Korean influencer, known as “Korea Grandma” on social media, exemplifies this philosophy. At 79, Park Mak-rye shares her routines online, from nutritious recipes to skincare regimens and exercise routines. Her dedication to daily activity and community engagement has become a model for others. “When I’m with friends laughing all day, there’s no room for sickness,” she said, capturing the essence of how social bonds and active lifestyles intertwine to support longevity.

Research reinforces these insights. A 2023 study linked consistent exercise to a 40% reduction in early mortality risks, while social isolation was associated with a 32% increase in the likelihood of premature death. Additionally, recent findings suggest that engaging with arts and culture may slow the aging process. These statistics paint a picture of a society that actively integrates health into daily life, rather than treating it as an afterthought.

Healthcare Systems in Focus

Comparing healthcare systems reveals another critical difference. South Korea’s model emphasizes early intervention, with regular check-ups and preventive measures becoming routine. Hieun Shin, a journalist with Agence France-Presse, explained that South Koreans often seek medical attention for minor ailments, such as a cold or backache, which fosters a culture of proactive care. “Prevention is woven into the fabric of healthcare here,” Shin remarked.

Conversely, the US system incentivizes treatment over prevention. Dr. Karen Studer, chair of the department of preventive medicine at Loma Linda University School of Medicine, noted that physicians are financially rewarded for diagnosing and treating diseases, not for addressing lifestyle factors. “A heart bypass surgery brings in thousands of dollars, but an office visit focused on diet and exercise earns much less,” Studer said. This structure can lead to a cycle where chronic conditions are managed rather than prevented.

The emphasis on early detection and routine care in South Korea aligns with its higher life expectancy rates. By prioritizing regular health assessments, the country addresses issues before they escalate. This approach also reduces long-term healthcare costs, creating a sustainable model that the US could adopt. As Swisher observed, “In South Korea, health isn’t just a goal—it’s a habit.”

Cooking, Culture, and Cognitive Health

The link between diet and cognitive function is a cornerstone of South Korean longevity strategies. Nutrient-rich meals, including those high in fruits, vegetables, and whole grains, are associated with lower risks of dementia and improved brain health. Diets like the Mediterranean and MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) have been shown to slow cognitive decline. These diets, often mirrored in South Korea’s traditional eating habits, highlight the importance of food in maintaining mental acuity.

Swisher’s visit to a school lunch program underscored how cultural norms shape health outcomes. The meals served are not just nutritious but also educational, teaching children about balanced eating from an early age. This early exposure likely contributes to the nation’s success in fostering healthier habits across generations. The contrast with American dietary patterns, where processed foods dominate, points to a need for systemic changes in how food is approached in schools and homes.

While the US faces challenges in curbing poor dietary habits, South Korea’s integration of health education into daily life offers a blueprint. By combining practical nourishment with cultural values, the country has created an environment where longevity is not just possible but expected. Swisher’s journey through this system reveals that the path to a longer life is often found in the small, consistent choices made each day.

As the world grapples with aging populations and rising healthcare costs, South Korea’s strategies provide a roadmap for improvement. From school lunches to preventive healthcare, the nation’s approach demonstrates that longevity is a product of collective effort and individual responsibility. By adopting these practices, the US could take significant steps toward reversing its trend of declining life expectancy and cultivating a healthier future for all.

“When I’m with friends laughing all day, there’s no room for sickness,” Park Mak-rye said, reflecting on how social connection supports her well-being.

The lessons from South Korea are clear: a focus on prevention, education, and community can transform health outcomes. As Swisher’s series illustrates, the journey to a longer life is not just about individual choices but about building a society that values and supports them. The US has much to learn from this model, and the first steps may start with rethinking how we approach food, exercise, and health in our daily lives.
