WASHINGTON — We’re deep into cold and flu season, and you’re likely reaching for any immune-boosting foods you can find. Fermented foods have been part of traditional diets for centuries. Today, foods like yogurt, kefir, and kimchi are often associated with gut health, but their effects on the immune system are still being studied.
New research suggests that kimchi, a Korean fermented food, may affect the immune system in a more targeted way than previously understood. By examining immune cells at the single-cell level, scientists were able to observe how regular kimchi consumption influenced immune balance and activity. Here’s everything you need to know about the new findings.
New Study: How Kimchi Influences Immune Cells
This study focused on how specific immune cells respond to a kimchi-based dietary intervention. Researchers from the National Research Council of Science & Technology had their new findings published in the journal Science of Food in November 2025.
The goal was to understand how kimchi affects immune cell behavior at a cellular and genetic level. Here is what to know.
