New research 1 underscores the potential role of pork consumption in supporting dietary and muscle health in Korean older adults. Older adults are a nutritionally vulnerable population who often face unique challenges, including meeting daily protein and micronutrient requirements.
The study,* conducted through a collaborative partnership between researchers from Gachon University in South Korea, Tufts University, Think Healthy Group, LLC, and other leading institutions, suggests that pork consumption may be positively linked to nutrient intake, diet quality and handgrip strength—an indicator of overall muscle strength in older adults.
Using 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:
Pork’s Role as a Carrier Food to Help Meet the Nutritional Needs of Older Adults
“Older adults are particularly susceptible to nutritional deficits, which can impact their mobility and quality of life,” said Dr. Hae-Jeung Lee, senior author and professor at Gachon University in South Korea. “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.

About National Pork Board
The National Pork Board has responsibility for Pork Checkoff-funded research, promotion and consumer information projects and for communicating with pork producers and the public. The Pork Checkoff funds national and state programs in consumer education and marketing, retail and foodservice marketing, export market promotion, production improvement, science and technology, swine health, pork safety, and environmental management and sustainability. For the past half century, the U.S. pork industry has delivered on its commitment to sustainable production and has made significant strides in reducing the environmental impact of pig farming. Through a legislative national Pork Checkoff, pork producers invest $0.35 for each $100 value of hogs sold. Importers of pork products contribute a like amount, based on a formula. For information on Checkoff-funded programs, pork producers can call the Pork Checkoff Service Center at (800) 456-7675 or visit pork.org .
