With Westernized diets contributing to rising chronic diseases, inflammatory conditions—linked to cancer and arthritis—are a growing concern. In South Korea, over 3 million people aged 60+ suffer from chronic inflammatory arthritis, highlighting the need for natural anti-inflammatory solutions.
The Rural Development Administration (RDA) of South Korea has discovered that the peel of the domestic purple potato variety ‘Jayoung’ possesses strong anti-inflammatory properties. In a key study, extracts from Jayoung potato peel inhibited PGE2 (Prostaglandin E2), a major inflammation and pain mediator, by more than 76%. This finding, patented in 2011 (Patent No. 10-2011-0049211), builds on earlier research (2009) showing that the flesh of colored potatoes suppresses prostate cancer cells.
Why This Matters for Agriculture & Health
Colored potatoes like Jayoung are not only rich in anthocyanins (potent antioxidants) but also offer:
- Better taste and texture (mild, less astringent, ideal for raw consumption or salads).
- Potential as a functional crop, increasing profitability for farmers.
- A sustainable use of peel, often discarded as waste.
Dr. Jincheol Jeong, Director of the Highland Agriculture Research Center at RDA, emphasized: “Since cancer progresses through inflammatory mechanisms, this research could extend into anti-cancer applications, making colored potatoes a staple health food.”
Global Trends Support Functional Potatoes
Recent studies reinforce the benefits of pigmented potatoes:
- A 2023 review in Food Chemistry found that purple potato anthocyanins reduce oxidative stress and inflammation.
- The global functional food market is projected to reach $275 billion by 2025 (Grand View Research), creating opportunities for bioactive crops like Jayoung.
The Jayoung purple potato peel is a high-value agricultural byproduct with proven anti-inflammatory effects. For farmers and agribusinesses, cultivating and promoting colored potatoes could open new markets in health foods, supplements, and natural remedies. For consumers, it’s a delicious way to combat inflammation naturally.
