Study highlights benefits of pork consumption for older adults in South Korea
· News-MedicalUsing data from more than 2,000 participants aged 65 years and older from the Korean National Health and Nutrition Examination Survey (2016-2020), the researchers compared the dietary habits and health indicators of pork consumers and nonconsumers. Findings showed that pork consumers showed beneficial relationships with:
- Greater intake of energy and nutrients such as protein, iron and B vitamins.
- Improved diet quality scores based on the Korean Healthy Eating Index, partially driven by a noted increase in total daily vegetable intakes.
- Higher handgrip strength, an accepted indicator of overall muscle strength and sarcopenia in older adults.
Pork's role as a carrier food to help meet the nutritional needs of older adults
Dr. Hae-Jeung Lee, senior author and professor at Gachon University in South KoreaOlder adults are particularly susceptible to nutritional deficits, which can impact their mobility and quality of life. This study demonstrates the role of pork as part of a balanced diet to help older adults meet their nutritional needs and maintain muscle strength."
The authors of this research suggest that pork intake may indirectly impact diet quality by acting as a carrier food, promoting higher consumption of other healthful components of the Korean diet (e.g., green vegetables). This is the third study to confirm pork's role as a carrier food in diets around the globe.1-3
Dr. Taylor C. Wallace, co-author, CEO of Think Healthy Group, LLC, and adjunct professor at George Washington University and Tufts University, noted that the Korean approach to pork consumption offers valuable insights for other countries aiming to improve the health of aging populations. "In South Korea, pork is often consumed as fresh, lean cuts rather than heavily processed forms, and it is traditionally paired with an abundance of nutrient-rich vegetables," he said. "This balance not only enhances diet quality but also delivers essential nutrients that older adults might otherwise lack, such as protein, iron and several key vitamins."
Integrating lean pork into a balanced, culturally relevant diet can address common nutritional deficiencies in older adults while supporting muscle health, and this approach not only respects diverse food traditions but also fosters healthier aging globally, explains Wallace.
A call for further research
The study emphasizes the importance of cultural context, as pork consumption patterns vary significantly worldwide. While the findings are specific to South Korea, they point to broader implications for aging populations globally. The authors advocate for clinical studies to confirm the benefits of pork consumption across different cultures and dietary contexts.
