The microbiome plays a key role in the competency of our immune defence. Dr Kalish explores three key ways that the GI tract interacts with and controls the immune system, including the role of mucosal immunity, digestion, and absorption of nutrients and commensal bacteria. New research shows the severity of certain diseases correlates with dysbiotic states, and that poor microbiome balance invites more serious health outcomes. We’ll also look at the role of stress and GI health, and how secretory IgA relates to our first-line immune defence.
We know that the brain and the gut are intricately interrelated – indeed the gut is often referred to as our second brain. Exciting new developments in the arena of the gut-brain axis (GBA) – also referred to as the ‘psychobiome’ offers promise for many mental health disorders.
