A recent clinical feeding study conducted by South Dakota State University highlights the benefits of incorporating lean pork into plant-forward diets for aging adults. The study, known as PRODMED, sheds light on the nutritional advantages of combining pork with plant-based proteins like lentils and chickpeas, offering a balanced approach to healthy aging.
PRODMED Study Reveals Key Findings
The 18-week crossover randomized controlled trial compared diets focused on lean pork with those based on plant proteins. Despite both diets containing similar levels of protein, fiber, and macronutrients, the pork-centered meals showed significantly higher protein quality. The pork meals had a Digestible Indispensable Amino Acid Score of 122.7, compared to 82 for plant-based proteins. This difference underscores the superior quality of protein and amino acids in pork, which are especially important for older adults.
Higher Acceptability and Satisfaction with Pork-Based Meals
The PRODMED study also found that participants rated the pork-centered meals higher in terms of satisfaction, satiety, and willingness to continue the diet post-trial. In fact, twice as many participants expressed interest in continuing meals that combined pork and plants in their long-term diets. This indicates that the inclusion of pork not only supports health but also enhances the overall meal experience.
The Role of Flavor in Healthy Eating
Taste plays a pivotal role in food choices, according to the International Food Information Council (IFIC). The PRODMED study emphasized the importance of flavor, pairing pork with a variety of vegetables, grains, and global flavors to create meals that were both nutritious and appealing. Popular vegetables included carrots, broccoli, bell peppers, onions, green beans, and spinach, while grains like brown rice, quinoa, and whole wheat pasta were frequently used in the pork meals.
Pork’s Role in Modern, Plant-Forward Diets
The findings suggest that pork can complement plant-based diets rather than competing with them. Researchers believe pork’s familiar, well-accepted flavor adds a savory element to plant-forward meals, making them more enjoyable for older adults. The study demonstrated that a combination of pork and plants provides a balanced approach to healthy aging, supporting both nutritional needs and meal satisfaction.
A Transformative Moment for the Pork Industry
The results of the PRODMED study come at a time when the National Pork Board (NPB) is promoting a campaign to reposition pork as a versatile, flavorful, and nutritious component of modern diets. By emphasizing flavor and scientific rigor, the campaign aims to showcase how pork can be part of healthy, plant-forward lifestyles.
David Newman, Ph.D., senior vice president of market growth at NPB, expressed that the study brings clinical evidence to the campaign’s message, supporting the idea that pork can play a key role in today’s dietary trends while still offering exceptional taste and quality.
Practical Applications for Healthy Aging
One of the unique elements of the PRODMED study was its real-world approach. Meals were pre-portioned, ready-to-eat, and developed by chefs in collaboration with clinical researchers. This practical model can be replicated by healthcare professionals, long-term care facilities, and even home cooks to support healthy aging through high-quality protein.
Kristen Hicks-Roof, Ph.D., RDN, LDN, director of human nutrition at NPB, emphasized that the study provides a replicable model for promoting healthy aging. By incorporating flavorful, familiar meals like pork-based dishes into daily diets, older adults can enjoy better nutrition without sacrificing taste.
Conclusion
The PRODMED study highlights the benefits of combining lean pork with plant-based proteins for older adults, demonstrating that pork not only provides high-quality protein but also enhances the overall meal experience. With findings like these, the National Pork Board is reshaping how pork fits into modern, health-conscious diets, ensuring its place as a vital and flavorful part of the future of food.
