Welcome back to The WHOLEistic Psychology Podcast 🤍
This one is a real treat for me, because my guest today is one of my fabulous PhD supervisors, Professor Grant Schofield. Grant is one of New Zealand's best-known public health scientists, a researcher, and the co-founder and Chief Science Officer of PREKURE. He's also the author of five best-selling books, with his newest, Choose Your Hard, just out in the world.
Grant has spent his career asking the unpopular questions about how we eat, how we move, and what we've been told is "healthy", and then following the actual evidence wherever it leads. In this conversation we pull apart the food system most of us grew up inside: the food pyramid, the Health Star Rating, and the food rules that shaped a generation, and we look honestly at what all of that has done to our metabolic health and our minds.
Buckle up, because we cover a whole lot of ground - from the food pyramid to psychiatric medication, and from AI robots and metabolic psychiatry. We get into the science, but we also stay human.
It's a warm, honest, occasionally cheeky conversation with one of the people who has shaped how I think about food and the brain, and I can't wait for you to hear it.
In this episode, we explore:
✨ How the food pyramid came to be, who it really served, and why the advice so many of us grew up with was built on shaky ground
✨ The Health Star Rating decoded: how a chocolate drink, a Up & Go or a bowl of Coco Pops can score so well, and what the rating system genuinely can't see
✨ What "ultra-processed food" actually means, and why the level of processing may matter as much as the nutrients on the label
✨ The link between how we eat and how we feel, and what the research is showing us about food, metabolic health, and conditions like depression and anxiety
✨ The emerging world of metabolic psychiatry, including the early research on ketogenic approaches for serious mental illness, and how to hold that evidence honestly
✨ Where Grant thinks medicine gets it wrong on informed consent, SSRIs, and treating the body and mind as separate systems
✨ What Grant would change first if he had full power over the food environment tomorrow, and where he sees AI fitting into how we understand our food
✨ The heart of Choose Your Hard: why every path has a hard, and how choosing the right one changes everything
✨ A grounded, compassionate way to think about food and your mind that doesn't tip into fear, restriction, or shame
✨ A gentle note from me: we touch on mental health, antidepressants, and psychiatric treatment in this episode. Nothing here is medical advice, and it's never a reason to stop or change any medication on your own. Please take what's useful, leave what isn't, and be kind to yourself as you listen.
