Listen to a Podcast About Gut Health

Discover the gut-brain axis and the trillions of microbes shaping your health — probiotics, prebiotics, fermented foods, and emerging research linking gut flora to mood, immunity, and disease.

Approximately 70-80% of the body's immune cells reside in the gut-associated lymphoid tissue (GALT), making the digestive tract the largest immune organ in the body. Fermented foods like kimchi, kefir, and sauerkraut contain live probiotic bacteria, and a 2021 Stanford study published in Cell found that a 10-week high-fermented-food diet increased microbiome diversity and decreased 19 inflammatory markers. The vagus nerve, the longest cranial nerve connecting the gut to the brain, carries an estimated 80% of its signals upward (gut to brain) rather than downward, providing the biological basis for the "gut feeling" intuition and explaining why gastrointestinal distress often accompanies anxiety and stress.
