REPLAY: Autoimmunity & the key role of the gut microbiome with Lisa Costa-Bir & Dr Brad Leech
from FX Medicine Podcast Central
Dr Brad Leech, Clinical Nutritionist and Herbalist joins fx Medicine by Bioceuticals ambassador Lisa Costa-Bir to unpack the intricacies of autoimmunity and the connection to the gut microbiome. Brad shares a wealth of clinical pearls for practitioners with autoimmune patients by unpacking the clinical relevance and meaning of functional gut testing markers as he examines how practitioners can use testing as a tool to identify inflammatory risk factors associated with autoimmunity and individualise treatment protocols for patients using diet, lifestyle, and supplemental support. Brad describes the clinical significance of establishing balance and healthy diversity within the gut using food as medicine, rather than focusing on elimination. Together, they also explore lifestyle factors that impact the gut microbiome, and how managing stress and using targeted supplementation to achieve a balanced gut microbiome can contribute to lowering autoimmunity risk factors in our patients.
