Episode notes
Peanuts Boost Brain Vascular Function
- Eating unsalted, skin-roasted peanuts (about 60 g/day) improved brain vascular function and memory in a 16-week Maastricht study.
- Gary Null highlights this as a simple dietary step to support cognition if not allergic.
Ultra-Processed Foods Alter Brain Structure
- A global study of 30,000 brain scans linked high ultra-processed food intake to alarming differences in brain structure.
- Gary Null warns ultra-processed foods (chips, sugary cereals, processed meats) harm brain health beyond metabolic disease.
Walk Daily To Slow Cognitive Decline
- Walk regularly: Harvard's report says ~5,000 steps/day can slow Alzheimer-related brain changes, and Gary recommends up to 15,000 steps.
- Prioritize brisk, continuous walking (power walking) over slow, sporadic movement.
