Big Lessons the US Can Learn from a Country with One of the Fastest-Growing Lifespans
Big lessons the US can learn – When it comes to extending life, South Korea is outpacing the United States in ways that defy expectations. A recent report from the World Health Organization highlights a remarkable 7.94-year surge in life expectancy across the country from 2000 to 2021, placing it among the leaders in global longevity. For those seeking to maximize their healthspan, the practices of South Koreans offer a blueprint that American society might need to adopt more seriously. While the U.S. has slipped to the bottom of developed nations in terms of life expectancy, South Korea’s approach to nutrition, activity, and preventive care is redefining what it means to live well into old age.
The Power of Nutritional Strategy
During a visit to a South Korean school, journalist Kara Swisher observed a stark difference in what children were consuming. Rather than the typical American fare of processed snacks and sugary beverages, the lunches featured nutrient-rich options like lettuce wraps, radish-chive salads, and seasonal fruits. These choices are not random—they are the result of a structured policy. Each school employs a dedicated nutritionist, such as Yeonju Kim, to design meals that balance health and education, ensuring students receive essential nutrients without sacrificing taste.
“Children’s meals are an opportunity to instill lifelong habits,” said Yeonju Kim, a school nutritionist. “We aim to make healthy eating enjoyable and accessible.”
This system reflects a broader cultural emphasis on food as a tool for health. In contrast, the U.S. struggles with basic dietary compliance. A 2023 CDC study found that nearly half of children aged 1 to 5 fail to consume a daily vegetable, while a third skip fruit altogether. These patterns persist into adulthood, with a 2025 study revealing that almost half of American adults follow poor-quality diets. The American Heart Association’s primary diet score, which prioritizes whole grains, lean proteins, and minimal processing, is a benchmark for better health. Diets like MIND and Mediterranean—known for their protective effects against cognitive decline and extended lifespan—are rarely replicated in the U.S. without deliberate effort.
The challenge lies in habit formation. American parents often face the dilemma of feeding picky eaters, leading to reliance on convenience foods. In South Korea, however, the focus is on education and accessibility. By integrating nutrition into daily routines, children develop a preference for wholesome meals, which sets the stage for healthier adult habits. This proactive approach is not limited to schools; it extends to the broader societal mindset, where food is seen as a foundation for longevity rather than an afterthought.
Activity and Social Connection as Pillars of Health
Beyond diet, South Korea’s cultural commitment to activity and social engagement plays a critical role in extending life. Dr. Geon-Ha Kim, a neuroscientist at Ewha Womans University Medical Center, identified physical exercise, social interaction, and mentally stimulating activities as key factors in the longevity of “SuperAgers”—older adults who retain cognitive abilities typically seen in much younger individuals.
“The difference between those who age gracefully and others is often found in their daily routines,” Dr. Kim explained. “Movement, connection, and curiosity all contribute to resilience.”
These principles are embodied in the life of Park Mak-rye, a 79-year-old social media sensation known as “Korea Grandma.” Through her online content, she shares recipes, skincare routines, and exercise regimens that reflect a holistic view of health. Her regimen includes regular physical activity, social gatherings, and a diet rich in fermented foods and antioxidants, all of which align with South Korea’s traditional emphasis on balance and moderation.
Research underscores the value of these habits. A 2023 study linked regular exercise to a 40% reduction in early death risk, while social isolation was associated with a 32% increase. Even more intriguingly, a recent study suggests that engagement with arts and culture may slow the aging process. Park’s philosophy—“I’m with friends laughing all day. There’s no room for sickness”—captures the essence of a society that views health as a collective endeavor rather than an individual struggle.
Healthcare Systems and Preventive Care
One of the most striking contrasts between the U.S. and South Korea is their approach to healthcare. Hieun Shin, an AFP journalist covering life in South Korea, noted that the system prioritizes prevention over treatment. This mindset is evident in the frequency with which South Koreans consult healthcare professionals, whether for minor ailments like a cold or more serious conditions such as back pain. In the U.S., however, the financial incentives for doctors favor treatment over proactive care.
“Physicians are paid to fix problems after they arise, not to prevent them,” said Dr. Karen Studer, chair of the department of preventive medicine at Loma Linda University. “This creates a cycle where chronic diseases are treated rather than avoided.”
South Korea’s model includes regular health check-ups, early intervention, and a culture of wellness that encourages people to seek care before symptoms become severe. This system reduces the burden of chronic diseases, which are a leading cause of premature death in the U.S. The emphasis on prevention is not just about medical interventions but also about lifestyle education, fostering a population that is more aware of and invested in their long-term health.
For the U.S. to catch up, it must rethink its healthcare incentives and prioritize education. If American families can adopt the South Korean approach to school lunches and healthcare professionals can shift their focus from reactive treatment to preventive strategies, the impact could be profound. The data is clear: longevity is not just about genetics—it’s about choices made daily, from the food on the plate to the company around the table.
As the CNN Original Series “Kara Swisher Wants to Live Forever” continues to explore the science of aging, it’s evident that South Korea’s success is a combination of cultural values, policy decisions, and individual commitment. The lessons from this country are not just about what to eat or how to exercise—they’re about creating a society that values health as a shared goal. With the right mindset, the U.S. could turn these insights into a transformative strategy for extending not just life, but the quality of it.
