🧠 Your diet isn’t just about weight or energy, it literally builds your brain. From the membranes and neurotransmitters that shape focus and mood to the habits that slow cognitive ageing, what you eat today determines how you think tomorrow.
💬 “Science always reserves the right to change its mind, and it will. There’s an adage they tell medical students that fifty percent of what they teach in medical school is going to be wrong within the next decade… The point is, we have to stay humble and open-minded enough to evolve as the evidence does.” – Max Lugavere
Max Lugavere is a health and science journalist, filmmaker, and bestselling author focused on brain health and preventive nutrition. His books, Genius Foods, The Genius Life, and Genius Kitchen, translate research into everyday practice. He hosts The Genius Life podcast and created the documentary Little Empty Boxes, spotlighting cognitive decline and lifestyle factors. Max’s work bridges rigorous evidence with realistic habits people can adopt now.
In this conversation, Tim and Max explore:
➡︎ The Prevention Mindset: What’s changed between generations and why environmental toxins, air pollution (PM2.5), and solvents (e.g., TCE) matter.
➡︎ Food for Cognitive Health: How ultra-processed foods harm the brain, why sugary drinks hit hardest, and how eggs, greens, and quality meat supply choline for acetylcholine, lutein and zeaxanthin for cognitive ageing, and protein to steady mood, focus, and appetite.
➡︎ Creatine Beyond the Gym: Doses, sleep deprivation support, and a small pilot in Alzheimer’s showing cognitive and strength benefits.
➡︎ Fermented Foods for Gut-Brain: Stanford findings on inflammation and diversity; simple foods that work.
➡︎ Stress and Light Exposure: The overlooked daily habits that anchor circadian rhythm and reduce cognitive drag.
