Dr Karan Explores How Food Builds Your Brain: Cooking Special with The Brain Docs
Mar 30, 2026
Dean Sherzai, neurologist and brain health researcher, and Ayesha Sherzai, neurologist focused on nutrition and dementia prevention, lead a cook-along exploring how everyday food shapes brain, gut, and heart health. They build an anti-inflammatory curry, discuss fibre, omega-3s, gut–brain links, tofu and coffee myths, cooking techniques, and practical tips for flavor, texture, and freezing meals.

Episode notes
Color Diversity Means Different Gut Benefits
- 'Eat the rainbow' because different colors supply distinct polyphenols, fiber types, and carotenoids that act via diverse mechanisms. Variety feeds diverse microbiome functions.
- Ayesha Sherzai compares fiber types to vitamins: different fibers do different jobs for gut and brain health.
Test And Target Your Omega-3 Index
- Check your omega-3 index and supplement if you don't eat fatty fish. Aim for an omega-3 index of roughly 8–12%; below 6% associates with cognitive risk.
- Dean Sherzai recommends testing levels to guide DHA/EPA dosing, especially in early development and later-life prevention.
Small Early Hits Erode Brain Resilience Over Time
- Prevention builds resilience like pillars in a building; early small insults accumulate toward central failure decades later. Midlife habits compound into late-life cognition outcomes.
- Dean Sherzai uses the 30-million-pillar analogy to show why early lifestyle matters and why cumulative small harms matter.
