Kimchi

Overview
Kimchi is a Korean fermented vegetable dish that provides live probiotics, GABA, and postbiotic compounds supporting gut-brain axis communication and neurotransmitter balance.
Within the BRAIN Diet framework, fermented foods such as sauerkraut, kimchi, kefir, miso, and kombucha provide live microbes + postbiotic peptides; improved SCFA pools; vagal signaling [1][2].
Key Nutritional Highlights
- Kimchi and lacto-fermented vegetables deliver live lactic acid bacteria and organic acids [1]
- Fermented vegetables contribute postbiotic metabolites relevant to gut–brain axis modulation [2]
