## Resource

Your microbiome could be the missing link behind Parkinson's disease, chronic inflammation, sugar cravings, constipation, and more. In this fascinating episode of the Lisa Fischer Said Podcast, Lisa sits down with microbiome researcher and entrepreneur Martha Carlin to unpack the surprising connection between gut health, brain health, and chronic disease. After her husband was diagnosed with Parkinson's at just 44 years old, Martha began a decades-long journey into the science of the gut microbiome, probiotics, stool testing, and the toxic burden affecting modern health. They discuss the gut-brain axis, dopamine, constipation as an early warning sign of disease, probiotics, fecal transplants, red light therapy, sunlight exposure, and why your daily bowel habits may predict your long-term health. Martha also shares how dietary changes dramatically improved her husband's symptoms and how her research led to groundbreaking discoveries in microbiome science. 👉 Subscribe to the Lisa Fischer Said Podcast, join the newsletter at https://lisafischersaid.com/podcast/ , and follow @lisafischersaid for more.
