South Koreans experienced a significant increase in average height primarily due to improved nutrition and healthcare over the last century.
While genetics determine the potential height a person can reach during puberty, that potential was historically often stunted due to inadequate nutrition and poor health conditions. In the past 100 years, advancements in nutrition and healthcare have allowed individuals to reach their genetically predetermined height. South Korea provides a compelling example of this phenomenon.
Factors contributing to the increased height of South Koreans include:
- Improved Nutrition: Access to a more balanced and nutritious diet, especially during childhood and adolescence, has been critical. This includes increased protein and micronutrient intake.
- Better Healthcare: Enhanced access to healthcare services, including vaccinations and treatments for childhood illnesses, has reduced the impact of diseases that could stunt growth.
- Economic Development: South Korea's rapid economic growth has led to higher living standards, better sanitation, and overall improved environmental conditions, all contributing to better health and growth.
- Government Policies: Government initiatives focused on public health and nutrition have also played a significant role.
In essence, South Koreans' remarkable increase in height is a testament to the power of better nutrition, improved healthcare, and overall societal progress in allowing individuals to reach their full genetic potential for growth.
