The Sweaty Penguin

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.
