The science of sugar – why we're hardwired to love it and what eating too much does to your brain

What are the evolutionary origins of sugar cravings? What makes something taste sweet? And what does too much sugar do to the brain? This week we talk to three experts and go on a deep dive into the science of sugar.

Featuring Stephen Wooding, assistant professor of anthropology and heritage studies at the University of California, Merced; Lina Begdache, assistant professor of nutrition at the Binghamton University, State University of New York and Kristine Nolin, associate professor of chemistry at the University of Richmond.

And after the Canadian government agreed in principle to pay CAN$40bn (US$32bn) over discrimination against First Nations children by the country’s child welfare system, we talk to Anne Levesque, assistant professor at the faculty of law at the University of Ottawa in Canada, about the long fight for justice. (From 29m20)

Plus, Veronika Meduna, science and health editor at The Conversation in New Zealand, recommends analysis of the recent Tonga volcano eruption. (From 45m45)
