Overview
- The World Institute of Kimchi reported single-cell RNA sequencing data from a randomized 12-week trial in overweight adults.
- Participants received placebo, naturally fermented kimchi powder, or starter-cultured kimchi powder, with 13 individuals in each arm.
- Kimchi consumption strengthened antigen-presenting cell function and produced balanced differentiation of CD4+ T cells.
- Starter-cultured kimchi showed more pronounced signals for antigen recognition with greater suppression of unnecessary immune activity.
- The peer-reviewed paper appears in npj Science of Food, with authors noting the small cohort and cellular endpoints and outlining plans for broader studies and potential functional food and vaccine-related applications.
