SUGAR: Laurie Taylor explores the ways in which the sweet stuff has transformed our politics, health, history and even family relationships. He’s joined by Ulbe Bosma, Professor of International Comparative Social History at the Vrije Universiteit, Amsterdam, and author of a tour de force global history of sugar and its human costs, from its little-known origins as a luxury good in Asia to transatlantic slavery and the obesity pandemic.

Also, Imogen Bevan, Research Fellow in Anthropology at the University of Edinburgh, considers the bittersweet nature of sugar consumption and kinship in Scotland. During extensive fieldwork in primary schools, homes and community groups, she traced the values and meanings attributed to sugar – its role in cementing social bonding, marking out special occasions and offering rewards to children, in particular. Far from being a simple and pleasurable choice, she found it often had a fraught, morally ambivalent presence in family life.
