The gut’s link to Parkinson’s — and more takeaways from this week’s “Healthful”

In a recent episode of “Healthful,” Norah O’Donnell explores the significant connection between gut health and brain function, featuring insights from Dr. Trisha Pasricha, a gastroenterologist and head of the Gut-Brain Institute. Dr. Pasricha discusses the “first-gut theory” of Parkinson’s disease, suggesting that early symptoms like constipation and REM sleep disorder may originate in the gut before affecting the brain. She also highlights the protective benefits of GLP-1 medications against certain cancers due to their anti-inflammatory properties. Additionally, Dr. Pasricha emphasizes the importance of fiber, noting that 95% of Americans fail to meet their daily fiber intake goals, which is crucial for heart and brain health. This conversation underscores the vital role of nutrition in disease prevention and overall well-being.
