Summary
Dr Partha Nandi is a gastroenterologist who wants you to know that the key to preventing stroke, Alzheimer's and Parkinson's might not lie in the brain at all – it lies in the gut. He shares how inflammation in your gut today could be affecting your brain decades from now. And he reveals the five simple pillars that could help you protect your cognitive health for life.
In this episode:
- The gut-brain connection and why it matters for stroke, Alzheimer's and Parkinson's
- How inflammatory markers in the gut can predict Parkinson's
