ZOE Science & Nutrition

Humans have been in love with chocolate for thousands of years. But not all chocolate is created equal, both in terms of health and taste. In this episode, chocolate expert Spencer Hyman and Professor Sarah Berry will take us on a trip into cacao. They’ll teach us what distinguishes good chocolate from bad chocolate and how we can beat our impulse to binge.

Spencer breaks down how to produce craft chocolate. In six steps he will show us how we get from bean to bar. Sarah shares research into the health benefits of chocolate with a focus on fibre, flavanols and theobromine. They will also look at the controversy around the association between chocolate and heart health.
