Is flavour just a sensory experience? Or the secret key to eating for health? In this episode, Spencer Hyman, flavour expert and co-founder of Cocoa Runners, joins Professor Tim Spector, world-leading scientist in nutrition and gut health, to uncover how the food industry manipulates taste to make us overeat, and how rediscovering real flavour could transform our wellbeing.

Spencer reveals the fascinating science of flavour and why we “taste” with our noses, how chocolate became the world’s first hyper-palatable food, and why modern diets are full of fake flavours designed to make us eat faster. Tim explains how “big food” exploits the brain’s reward system to override fullness signals, creating products that keep us hooked - and what we can do to fight back.

For listeners curious about how to rebuild a healthy relationship with food, this episode includes a practical guide to retraining your taste buds. Spencer and Tim share tips on how to eat more slowly, savour each bite, and use flavour as a natural marker of nutrient-rich, satisfying foods.

Could learning the language of flavour be the most powerful way to eat better - without restriction?
