During the coronavirus pandemic, a global economic collapse, and increasingly frequent and severe droughts, what better time for southern African countries to see upticks in another disease: pellagra. Pellagra, a disease caused by chronic deficiencies in Vitamin B3 (niacin), is prevented with nothing more than a half-decent diet. So why is it still here in 2020? Today, we go on a journey through history to figure out what caused this vitamin deficiency disease to appear, why it still exists, and what we can do about it. With special guest Dr. Christopher Conz: Lecturer in African Environmental History at Tufts University.
