Your Brain on Food, Sleep & Stress: What Top Experts Want You to Know | Brain Health Masterclass

Your Brain on Food, Sleep & Stress: What Top Experts Want You to Know | Brain Health Masterclass

Author: Sarah Ann Macklin September 10, 2025 Duration: 1:22:49

We’re not taught how to protect our brains.

We’re not taught how food, sleep, and stress shape memory and mood.

We’re not taught why dementia is rising or that prevention starts decades earlier.

But we should be.


This week’s Brain Health Masterclass brings together leading neurologists, scientists, and longevity experts to explore what really keeps our minds sharp. From anxiety and PTSD to dementia, menopause, psychedelics, gut-brain connection, and even the oral microbiome, you’ll learn why your daily choices matter more than you think.


In this conversation, I’m joined by world-leading voices, including:

Dr. Lisa Feldman Barrett – neuroscientist redefining how emotions shape the brain

Dr. William Li – physician-scientist on food as medicine and brain regeneration

Dan Buettner – founder of the Blue Zones uncovering the world’s longest-lived communities

Dr. Sarah McKay – neuroscientist bringing clarity to women’s brain health

Dr. Chris Palmer – psychiatrist linking nutrition, metabolism, and mental health

Dr. Rick Doblin – pioneer in psychedelic research for trauma and healing

Dr. Katie Lee – oral microbiome researcher revealing surprising links to dementia

Drs. Ayesha & Dean Sherzai – neurologists on preventing Alzheimer’s with lifestyle


Together we explore:

- The Brain’s #1 Job (It’s Not What You Think)

- How gut health, diet, and even flossing impact dementia risk

- What Blue Zones teach us about friendship, purpose, and longevity

- The myths of menopause brain fog, and the resilience science reveals

- Can psychedelics safely rewire trauma circuits?

- Daily habits that protect memory, mood, and cognition


Love,

Sarah Ann 💛

The tone is refreshingly human-this isn't about perfection, but about finding a smarter, more integrated approach to everyday living.
