The workshop covers the gut–brain axis as a bidirectional communication network linking the gut and brain through neural, hormonal, and immune pathways, with the vagus nerve acting as a key connection. It explains how the gut microbiome influences digestion, immunity, mood, and cognition through neurotransmitter production and inflammation regulation. The session highlights how stress, poor diet, and lifestyle factors can disrupt gut health, leading to dysbiosis and increased intestinal permeability. It also emphasizes restoring gut–brain balance through fiber-rich diets, fermented foods, and holistic lifestyle practices to support both physical and mental well-being.
