Could Kimchi and Doenjang Be 'Ultra-Processed'? Debating UPF Standards

South Korea has no official definition for ultra-processed foods (UPFs), and applying the NOVA classification could controversially include traditional fermented foods like kimchi and doenjang. The NOVA system labels foods containing industrial ingredients not found in home kitchens—emulsifiers, artificial flavors, protein isolates—as UPFs. U.S. agencies are researching UPFs and FDA is working on legal definitions after studies linked UPF-heavy diets to overeating, weight gain, and higher dementia risk. Critics argue NOVA ignores nutritional composition: whole-grain breads or nutritious products could be misclassified if industrial additives are present. A Seoul National University–linked study found many Korean foods fall into an uncertain category under NOVA, suggesting Korea’s UPF energy share could range widely (21.5–38.1%). Experts recommend assessing individual foods’ nutritional profiles rather than blanket labeling; a Korea-specific nutrient-based criterion may be needed. (UPF: ultra-processed food)
